Abstract
The utility model provides a pre -buried stand tensioning device of highway, characterized by comprises roof, support column, lifting hook and chain block, the roof be a circular steel sheet, arrange according to equilateral triangle at its bottom surface edge to set up three U type connecting piece, a connecting hole has been opened down to the opening of this U type connecting piece among them, the support column be the steel pipe, it has the connecting hole to open at its top, three spinal branchs are in the charge of and are inserted respectively in the three U type connecting piece to bolt pass between them for the connecting hole fixed the articulating U type connecting piece with the support column of nut be in the same place, the lifting hook set up in the center of roof bottom surface, chain block hangs on the lifting hook. Adopt the utility model discloses small -size traffic facilities maintenance operation speed can be improved, electric power reduce cost is removed from, moreover easy operation, convenience, safety.
Description
Technical field
The utility model relates to highway facilities more exchange device, especially a kind of highway preburied column draw-off gear, is particularly suitable for the preburied column use that destroyed changed by highway.
Background technology
In speedway routine servicing process, must change in time, with the enforcement safety of the integrality and passing vehicle that ensure means of transportation the means of transportation (as column etc.) that traffic accident destroys.In existing technology, pile-driving and-pulling machine is generally used to carry out operation to pre-buried column.But for the speedway be open to traffic, pile-driving and-pulling machine directly cannot arrive accident point, can only by vehicle transport to accident road surface, but the manpower and materials that such operating type consumption is a large amount of, add maintenance cost, and efficiency is low, expection requirement cannot be reached.In addition, the road area shared by large-scale pile-driving and-pulling machine is comparatively large, has a strong impact on traffic, there is again larger potential safety hazard.This weak point existed in existing means of transportation just.
Summary of the invention
The purpose of this utility model is to overcome the problems referred to above that prior art exists, provide a kind of efficiency high, carry and a kind of highway preburied column draw-off gear easy to use.
To achieve these goals, the technical scheme that the utility model adopts is:
A kind of highway preburied column draw-off gear, it is characterized in that by top board, support column, suspension hook and Chain block composition, described top board is one block of circular steel plate, in its bottom edge, three U-shaped connectors are set by equilateral triangle layout, this U-shaped connector opening down, have a connecting hole therebetween, described support column is steel pipe, connecting hole is had at its top, three support columns are inserted in three U-shaped connectors respectively, with a bolt through both connecting hole nut fixing by U-shaped connector and support column hinged, described suspension hook is arranged at the center of top board bottom surface, Chain block hangs on suspension hook.
Technique scheme can take the following measure perfect further;
1. the top board described in preferably adopts Q325 steel plate to make, to ensure the intensity of top board.
2. the top board described in diameter 200 millimeters, thickness be 10 millimeters proper.
3. the support column described in is 40 millimeters to adopt diameter, length be the coating steel pipe of 2500 millimeters as well.
The utility model uses like this; Close track, road surface one during use, according to the stud damaged, install this column draw-off gear, operating personnel adjusts the height of three support columns, is finally gone to fulfil assignment by operation Chain block by constructor.
The beneficial effects of the utility model
1. can improve small-sized means of transportation maintenance activity speed, simple, convenient, safety.
2. remove mechanical generation driving force from, by manual operation, reduce costs.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, structure of the present utility model is further described.
Fig. 1 is a kind of front view of highway preburied column draw-off gear.
Fig. 2 is the upward view removing Chain block 4 in Fig. 1.
Detailed description of the invention
See figures.1.and.2, a kind of highway preburied column draw-off gear, it is characterized in that by top board 1, support column 2, suspension hook 3 and Chain block 4 form, described top board 1 is one block of circular steel plate, diameter 200 millimeters, thickness is 10 millimeters, make with Q325 steel plate, three U-shaped connectors 5 are welded with by equilateral triangle layout in top board 1 bottom edge, this U-shaped connector 5 opening down, have a connecting hole therebetween, described support column 2 is 40 millimeters with diameter, length is that the coating steel pipe of 2500 millimeters is made, connecting hole is had at its top, three support columns 2 are inserted in three U-shaped connectors 4 respectively, fixing that both are hinged through the connecting hole nut of U-shaped connector and support column 2 by a bolt, suspension hook 3 is welded in the center of top board 1 bottom surface, Chain block 4 hangs on suspension hook 3.
