Description

A pipe wiring device

technical field

The invention relates to a wiring device, in particular to a pipeline wiring device

Background technique

At present, the cables used for electrical wiring generally need to use a cable puller during the cable wiring operation in the cable duct. The front end of the head of the cable puller has a buckle that can bind nylon wires. When carrying out cable wiring operations, first push the front end of the cable puller head from one end of the pipe to the other end of the cable conduit until the front of the cable puller head is exposed from the other end; tie the nylon wire to the cable puller head Pull the front buckle back to the source; after that, use the nylon wire in the tube to pull the cable that you want to pull and route. This operation generally requires a group of 2 people to work at both ends of the pipeline. The operation process of this method requires a total of 3 steps, including: the puller is pushed forward to pass through the pipeline; then a nylon wire is tied in front of the puller and then Pull back to make the nylon wire pass through the pipe; finally tie a cable in front of the nylon wire and pull it forward so that the cable goes through the pipe.

The disadvantage of this construction method is that the distance of each wiring is generally difficult to exceed 30 kilometers due to factors such as the hardness of the wire puller, the curvature of the pipe itself, the roundness of the pipe, and the unevenness of the indirect pipe. This operation is also related to the experience and skill familiarity of the staff. For example, if you want to pull a distance of 100 meters, you generally need to divide it into multiple relays. At the same time, you need to install more junction boxes (junction-box) at the opening of the pipeline relay. Since two people need to work together at one time, the labor cost relatively expensive. In addition, if the pipelines to be wired are located on a high ceiling, the difficulty of the operation will be greatly increased, and the required time and labor costs will also be relatively increased.

In recent years, there has been another kind of operating equipment, which uses a high-pressure (positive pressure) carbon dioxide gas as power to drive a bullet-like object into one end of the pipeline, and pulls a nylon wire behind the bullet at the same time. After the bullet passes through the pipeline, Use the nylon wire drawn from the rear to carry out subsequent wire pulling operations. This method can travel 30 meters to 40 meters at a time under better conditions. The operation process requires 2 steps, including: the bullet pulls the nylon wire forward; after pushing out the pipe, tie a cable to the front of the nylon wire Pull back so that the cable runs through the conduit.

However, the device has the following disadvantages:

One of its disadvantages is that bullets are generally made of relatively hard materials and require appropriate weight to obtain sufficient kinetic energy. A certain amount of gas and pressure must be stored before each shot. When the bullet is fired at the beginning, the kinetic energy of the bullet is sufficient. If the pipe is a straight line without bending, and the connection between the pipe and the pipe is smooth and flat, the bullet can move up to 40 meters. It often happens that the joints of the tubes are not smooth and flat. After the bullet is fired, its kinetic energy drops immediately and is trapped in the tube. Because the kinetic energy and gas are released after a single shot, the bullet is stuck in the tube. There is no kinetic energy to move forward, but the nylon rope pulled behind may continue to move forward due to inertia, causing the nylon wires to become tangled together, causing even greater trouble.

The second disadvantage is: high-pressure carbon dioxide gas is a special material, which is generally not easy to obtain, and the cost of equipment and materials and each supplementary filling is high; it needs to be installed in a heavy steel cylinder, which is inconvenient to fill and carry; it has potential danger, that is, the explosion of the steel cylinder Or when the bullet passes through the pipeline, the force cannot be controlled, the initial velocity of the bullet is too fast, and the nylon wire tied at the rear end may cut people); the gas stored in the steel cylinder is limited and cannot be supplied for a long time, and cannot be directly replenished at the general construction site gas.

In summary, the industry urgently needs to provide a pipeline routing device that can overcome the above-mentioned shortcomings.

The flap 22 is arranged around the periphery of the shuttle body 21, which enhances the airtight performance of the shuttle 20 and the pipeline on the one hand, and overcomes the situation that the pipeline is bent and the construction pipeline is not smooth on the other hand. There is at least one split slit (not shown) on the flap 22 to provide airtight and stable air flow, so that the shuttle is not easy to shake and spin when it advances in the pipeline. Depending on the type of pipe, there may be no splitting cracks. As for the number of groups of the flaps 22 and the number of the dividing slits arranged on the flaps 22, those skilled in the art can completely set and implement them according to the specific situation, and will not be described in detail here.

The flap 22 is made of a material with good elasticity and softness. In this embodiment, synthetic rubber or sponge material is used to provide good elasticity to overcome the bending of the pipeline and the unevenness of the construction pipeline.

The material of the shuttle body 21 is selected from materials with good elasticity and softness. In this embodiment, synthetic rubber or sponge is used to provide good elasticity, which can not only overcome the bending of the pipeline and the unevenness of the construction pipeline, but also improve the airtight performance.

The method for using the pipeline routing device includes the following steps: 1. First measure the length of the pipeline to be routed to ensure that the length of the pipeline is lower than the effective length. 2. Put the shuttle tied with the wire into the port (front port) of the construction pipeline, and connect the negative pressure generating device to the other end (end) of the construction pipeline. Start the negative pressure generating device to generate a suction force or a pulling force, so that the shuttle and the wire attached at the rear end are absorbed and passed through the pipeline to the negative pressure source outlet at the other end (end) of the pipeline. If there is no negative pressure suction, it may be that the pipe is blocked, or the pipe joint is not tight enough to create an airtight space. 3. Untie the wire on the shuttle, tie it to the end of the cable to be routed through the pipe, and pull the wire back along the pipe from the other end (end) to complete the pipe wiring. This method requires only one person to complete the work of pipeline wiring.

When it comes to corners, turn with ease while remaining airtight with no loss of pressure.

3. The exterior design of the shuttle itself has at least one set of soft flaps, and there is at least one split slit on the flaps. This design is to provide a more reliable airtight function for guiding the shuttle in the pipeline. The flaps and The slits have the effect of stabilizing the airflow, so that the guide shuttle itself is not easy to shake and spin when it advances in the pipeline.

4. Since the air-tight function of the shuttle is good, and the negative pressure source is stable and sustainable, the negative pressure power required during operation does not need to be too large. If a high-speed blower is used, only a small (light) blower can provide enough Power, so it is easy to carry, it can be regarded as a kind of personal power tool, especially suitable for engineering site operations.
