Technical Field

The utility model relates to a supporting tool, especially a portable supporting tool for supporting large-scale marine low-speed diesel engine spare part.

Background

After several large parts of the marine low-speed diesel engine are manufactured, the parts need to be temporarily placed in a certain place, and a specific supporting tool needs to be used for supporting in the placing process. And these supporting tools are frequently moved in position according to the size and place of the components.

In the prior art, a columnar iron heading is used as a supporting tool to support large parts. In order to realize that this iron heading can remove, two lugs have been fixed in the symmetry welding on the lateral wall of iron heading, have the through-hole on this lug. When the iron heading needs to be moved, the lifting lug is lifted by the lifting equipment so as to pull the iron heading, and the iron heading is lifted and pulled to a required position by the lifting equipment.

The iron heading in the prior art has the following problems:

the heading weight of the iron used as a supporting tool is often large, and the iron is difficult to move and position.

Moving the iron heading by adopting a travelling crane or a forklift, and adjusting the position of the iron heading one by one, thereby wasting a lot of time and occupying the use of the travelling crane and the forklift.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome exist not enough among the above-mentioned prior art, provide a portable supporting tool to solve the inconvenient problem of removing of supporting tool among the prior art. Utilize the utility model discloses a portable supporting tool can change the position of supporting tool as required at any time, need not to use hoisting equipment again and hangs and draw the location to it.

The technical scheme of the utility model:

a movable supporting tool comprises a cylindrical iron heading, wherein two lifting lugs are symmetrically arranged on the side wall of the iron heading, the top end of the iron heading is a support platform, a sleeper is placed on the support platform, the bottom end of the iron heading is a seat plate, the outer diameter of the seat plate is larger than that of the iron heading, four large rib plates are symmetrically arranged at the included angle between the seat plate and the outer wall of the iron heading, the total weight of the iron heading, the support platform and the sleeper is G1, the movable supporting tool is characterized in that a fixed support is arranged on the side wall of the iron heading between every two adjacent large rib plates, one end of the fixed support is fixed on the outer wall of the iron heading, the other end of the fixed support is provided with a through hole, a movable part is arranged in the through hole and comprises a long rod bolt, one end of the long rod bolt is provided with an external thread, a foot rest is fixed on a screw cap at the other end of the long rod bolt, one end of the long, the lower extreme of this nut is close to in the upper surface of fixed bolster, the foot rest on install the truckle, stock bolt go up the cover and have a spring, the elastic modulus of this spring is E, the upper end of this spring leans on the fixed bolster, the lower extreme leans on the spiral shell lid, the bedplate that iron was upset when shown truckle lands is apart from ground height to be L, satisfies the formula:

e is more than G1, the weight of the object placed on the sleeper is G2, and the formula is satisfied: g1+ G2 > E × L.

The fixed support at the upper end of the spring is provided with a first spring retainer ring, and the foot rest at the lower end of the spring is provided with a second spring retainer ring.

The technical advantages of the utility model:

the utility model provides a portable supporting tool installs four movable truckles all around at the base of an iron heading to fix on the truckle support of iron heading side by spring and hex bolts. When the iron holder is in a free state, since the elastic force of the spring is greater than the weight of the iron holder itself, the iron holder lands on the ground by four casters and supports the body to be freely movable. On the contrary, when the iron upset supports the heavy object, the bottom surface of the iron upset is grounded to play a supporting role. If the conventional support needs to be lifted by a crane or moved by a forklift when moving, a large amount of manpower and material resources are wasted. The design solves the problem that the work efficiency is improved only by manual pushing. The device is suitable for placing a plurality of parts when the low-speed diesel engine is assembled and disassembled, and has simple structure and wide application range.

Detailed Description

The structure and application of a large mobile support tool of the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments, but the scope of the invention is not limited thereto.

Referring to fig. 2 and 3, fig. 2 is a top view of a mobile supporting tool of the present invention.

Fig. 3 is a front view of a portable support tool of the present invention. As can be seen from the figure, the utility model discloses a portable supporting tool, including circular shape tube-shape iron upset 1, the symmetry is equipped with two lugs 11 on this iron upset 1's the lateral wall, is equipped with the hole that can wear to erect equipment wire rope on the lug 11, and hoisting equipment can hang through lug 11 on this supporting tool and draw its to the construction site, comes to support large-scale spare part temporarily. The top end of the iron heading 1 is provided with a support table 3, and a sleeper 4 is placed on the support table 3. The large-scale parts are not directly placed on the upper surface of the iron heading 1, but are supported after being cushioned by the sleepers 4 on the pallet 3.

The bottom end of the iron heading 1 is a seat plate 13, and the seat plate 13 is contacted with the ground when in use. The outer diameter of the seat plate 13 is larger than that of the iron heading 1, four large rib plates 14 are symmetrically arranged at the included angle between the seat plate 13 and the outer wall of the iron heading 1, and the total weight of the iron heading 1, the saddle 3 and the sleeper 4 is G1.

The utility model is an improvement on the original supporting tool, a fixed bracket 12 is arranged on the side wall of the iron pier 1 between every two adjacent large rib plates 14 of the original supporting tool, a small rib plate 15 is arranged at the included angle between the fixed bracket 12 and the outer wall of the iron pier 1, one end of the fixed bracket 12 is welded on the outer wall of the iron heading 1, the other end is provided with a through hole which is communicated up and down, a moving component 2 is arranged in the through hole, the moving component 2 comprises a long rod bolt 21, one end of the long rod bolt 21 is provided with an external thread, a foot rest 24 is fixed on a screw cap at the other end, the long rod bolt 21 is sleeved with a spring 23, one end of the long rod bolt 21 provided with external threads can pass through a through hole on the fixing support 12, a nut 22 is screwed on a screw rod of the long rod bolt 21 which penetrates out of the fixing support 12, the lower end of the nut 22 abuts against the upper surface of the fixed bracket 12 by means of a standard washer.
