BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric vehicle stop installed and used in a parking lot, an entrance of a public facility or the like, and more particularly to a geared wire load reducing device used for its operation.

[0002]

2. Description of the Related Art A vehicular stop that prevents the entry of a vehicle by the upward movement of an elevating pole and makes this possible by its submergence has been proposed, for example, by Japanese Patent Application No. 5-248725 of the present applicant.

[0003] According to this, a plurality of car stops that allow the lifting pole housed in the buried case for underground mounting to be raised and lowered freely by the lifting means interposed therebetween, for example, a plurality of these car stops. It is configured to be configured as a plurality of interlocking electric car stops including a motor stop actuating device that simultaneously operates the car stop elevating means.

The elevating means is, for example, one for rotating one chain sprocket by a pair of upper and lower chain sprockets and a rotating chain wound around them and connected to an elevating pole, or a winding shaft and the winding. By means of a winding wire that can be wound around a shaft and is also connected to an elevating pole, a rotating force such as one for rotating the winding shaft is used, and the operating means is, for example, a motor-driven rotating chain or a geared wire. (Drive wire) and a chain sprocket that is installed at the tip of the rotating shaft protruding outside the embedded case for transmitting the rotational force of the chain sprocket, the winding shaft, etc., and meshes with the rotating chain or geared wire. It is configured such that the elevating means is operated simultaneously by gears and gears.

[0005]

In order to put such a plurality of interlocking electric bogies into practical use, for example, the operating means is a combination of geared wires and gears, among others, for installation and maintenance. Simple and easy.

That is, since the geared wire is made up of a series of members and rotates back and forth bidirectionally and is flexible to a certain extent, it is installed by itself outside the embedding case of underground installation, while it is installed above the ground. It is easy to arrange it so that it bends upward with respect to the motor side that should be installed, and because it is a series, it can be attached and detached at the time of installation and maintenance by inserting and withdrawing it into the protective pipe Because it is.

However, when the actuating means including the geared wire and the gear wheel is used, the gear teeth of the geared wire are relatively easily damaged. That is, since the geared wire is formed by helically winding and fixing gear teeth around the outer circumference of the wire, for example, when there is a factor that impedes the rotation of the gear gear side, the gear teeth of the geared wire are excessively large. This is because a load is applied, especially when it is necessary to operate each elevating means of the plurality of car stop units, or when there is a circumstance where the operation of the elevating means is not performed smoothly in any of the car stop units. The likelihood of missing gear teeth increases.

The present invention has been made in view of the above circumstances, and a problem to be solved by the present invention is to provide a load to a geared wire in an electric vehicle stop using a geared wire and a gear gear meshing with the geared wire as the operating means. It is an object of the present invention to provide a geared wire load reducing device for an electric vehicle stop that reduces gear teeth as much as possible to prevent gear tooth loss.

[0009]

According to the present invention, in accordance with the above-mentioned problems, the gearing is caused by a malfunction of the elevating means due to the deflection or deviation of the elevating pole expected when the elevating pole is moved up and down with respect to the embedded case. In order to reduce the load on the wire, or to reduce the load on the geared wire due to the frictional resistance caused by the contact and sliding contact of the lifting pole with the embedded case, ensure that the lifting pole goes up and down vertically. In addition, the guide roller is used to prevent frictional resistance, and the weight of the lifting pole is used to reduce and reduce the load applied to the geared wire, especially when the protrusion rises.

The gears 36 are rotated at the same time, and the geared wires 37 are rotated forward and backward by the motor 40 to rotate the gears 36 and operate the elevating means 27 simultaneously.

As a result, in the present example, the lifting poles 5 of the bollard stop units B, which are installed in the ground and are arranged in three rows, are provided.
In the same way, the projecting ascent and the descent descending and descending are performed in conjunction with each other, and the projecting ascent prevents the vehicle from entering, and the immersing descent makes this possible.

At this time, in the electric car stop A of this embodiment, a guide roller 12 is provided between the embedding case 1 of each car stop unit B and the lifting pole 5 to guide the lifting / lowering of the lifting pole 5. There is.

The guide roller 12 of this embodiment is installed at a plurality of positions in the outer circumferential direction of the elevating pole 5 so that the inner wall of the embedding case 1 serves as a guide wall, and is placed between the embedding case 1 and the elevating pole 5. It is provided as an intermediary.

That is, each embedding case 1 of the present example is a rectangular or rectangular hollow with a flange 2 protruding from the upper end and made hollow with a thick steel bottom, and a circular through hole 4 is provided therethrough. The top plate 3 made of cast aluminum is detachably fastened with bolts (not shown), while the lifting pole 5 is
It is in the form of a large-diameter cylindrical hollow pipe with an upper end closed and a lower end opened, in which a cap 6 made of aluminum casting is fitted and fixed to the upper end.

In this embodiment, the guide roller 12 uses the inner walls of the rectangular or rectangular embedding case 1 as the guide walls, and the lower peripheral wall of each elevating pole 5 is 90 ° in the outer peripheral direction.
It is assumed that it is installed in four places for each and that it is installed in a total of eight places, each of which has two stages above and below.

Each guide roller 12 uses a U-shaped frame 13 and a roller unit in which a pair of rollers 14 are rotatably fixed to the frame 13 so that the tip ends thereof project from the frame 13. 5 is installed by being screwed and fastened to the receiving frame 15 which is welded and fixed at a predetermined position of 5.

By interposing this guide roller 12,
When the hoisting and lowering pole 5 goes up and down, it prevents its deflection and deviation and makes it as vertical as possible to ensure hoisting without friction resistance.
By eliminating the cause of the rotation failure of the gear gear 36 side due to the malfunction of the elevating means 27 and friction, the load on the geared wire 37 meshing therewith is eliminated and reduced, and the gear tooth is prevented from being damaged.

Further, in the electric bobbin A of this embodiment, the balancer means 16 for canceling the lifting load of the lifting pole 5 as much as possible is installed together with the guide roller 12 for eliminating and reducing the load on the geared wire 37. There is.

The balancer means 16 of this embodiment comprises a guide pipe 18 which is erected on the bottom wall of the embedding case 1, a pair of suspension wheels 20 which are bulged on both sides of the upper end of the guide pipe 18, and the guide pipe. A weight balancer 22 is provided by inserting the guide pipe 18 through a central through hole so that 18 serves as a vertical movement guide, and both ends are fixed to the weight balancer 22 and supported by the pair of suspension wheels 20 in a wound manner. Inside the hollow portion of the guide pipe 18 so that the hanging wire 23 is suspended from the upper end of the elevating pole 5 and the intermediate portion in the longitudinal direction of the hanging wire 23 can be pushed down to the lower end or downward. And a projecting rod 24 inserted into and disposed in.

In the balancer means 16 of this embodiment, the guide pipe 18 is erected so that the lower end of the guide pipe 18 is screwed to the bottom wall of the embedding case 1 and is directed upward to the relatively short guide post 17. By fitting, it stands upright at the central position of the bottom wall of the embedded case 1.

In order to extend the pair of suspension wheels 20 to the guide pipe 18, a suspension vehicle unit 19 in which the pair of suspension vehicles 20 are pivotally fixed is used, and a cylindrical fitting portion 21 provided below the suspension vehicle unit 19 is mounted on the guide pipe 18. It is carried out by fittingly fitting the upper end to the upper end of the guide post 17 and projecting the guide post 17 at both ends in view of the relative positional relationship between the pair of suspension wheels 20 and the cylindrical fitting portion 21 in the suspension vehicle unit 19.

The weight balancer 16 has a weight equivalent to the weight of the lifting pole 5 in this embodiment, has the central through hole for inserting the guide pipe 18 in the center, and has a thickness smaller than the inner diameter of the lifting pole 5. It has a cylindrical shape.

The suspension wire 23 having both ends fixed to the weight balancer 22 is made to have a length corresponding to the amount of lifting and lowering of the lifting pole 5, so that the pair of suspension vehicles 20 can be connected to each other.
The hanging wire 23 is supported in a hooked manner by the protruding rod 24 of the lifting pole 5 and the lifting wire of the lifting pole 5 is pushed down by the protruding rod 24 of the lifting pole 5 so that the weight balancer 22 can lift the lifting load of the lifting pole 5. We try to offset as much as possible.

The hanging fixing of the projecting rod 24 to the elevating pole 5 is as follows.
In this example, the cap 6 is fitted and fixed to the bracket 9 that is welded and installed inside the vicinity of the upper end of the elevating pole 5, and the female screw portion 1 below the screw block 10 for fixing the cap 6.
1 is carried out by screwing the male screw portion 25 at the upper end of the protruding rod 24. Further, the pushing down of the suspension wire 23 by the protruding rod 24 ensures the reliability of the pressing and the suspension wire 23.

By canceling the lifting load of the lifting pole 5 of the weight balancer 22, the factor that prevents the rotation of the gear gear 36 side due to the lifting load of the lifting pole 5 is eliminated, and the geared wire 3 that meshes with this is eliminated.
The load on 7 is eliminated and mitigated, and the loss of gear teeth is prevented.

The electric car stop A of this embodiment, which is provided with the guide roller 12 and the balancer means 16, is suitable for gearing because the elevator poles 5 of the triple-unit car stop unit B are simultaneously moved in and out. Wire 37 for each lifting means 2
Even if it is used as the actuating means 32 of No. 7, the elevating poles 5 can be made smoother and lighter in weight, so that the load on the geared wire 37 can be reduced as much as possible and structurally against the load. By using the relatively weak geared wire 37, it is possible to provide a plurality of interlocking car stops with its durability ensured in practical use.

Reference numeral 1 denotes a motor-side gear gear that connects the geared wire 37 and the motor 40.

Although the illustrated example is as described above, the elevating means 27 for rotating the take-up shaft of the take-up wire is used, and this is connected at each gear box part for maintenance of the geared wire. In this way, the guide roller is installed on the side of the embedded case, and the side wall of the lifting pole is interposed between them so that the balancer means is installed in place of the guide roller. The balancer means is constructed such that the weight balancer fits the lifting pole, the suspension wire is fixed to the projecting rod, the embedding case and the lifting pole are both cylindrical or rectangular or rectangular.
