Description
Technical Field
The utility model relates to a push bench pushes away hydro-cylinder frame clamping device relates to fields such as track traffic, tunnel engineering technique.
Background
Along with the urbanization construction process is constantly accelerated, city utility tunnel construction, the pipe pushing jack construction is generally applied to work under the narrow and small space in underground, has space utilization height, construction safety, short, the expense low grade advantage of cycle. The advancing work of the push bench is realized by the propelling action of the oil cylinder, the push iron, the pipe piece and the shield body are pushed to excavate, and then the residue soil is conveyed out of the starting well by the trolley. Whether the stability of the propulsion oil cylinder directly influences the progress of the whole project or not is judged, the existing propulsion oil cylinder adopts a fixing mode that a clamping block is additionally arranged outside an oil cylinder frame, and the influence of deviation caused by loose clamping easily occurs under the long-distance construction of a push bench.
Disclosure of Invention
The utility model aims to solve the technical problem that the skew phenomenon defect of the propulsion cylinder because of the not tight production of clamping to prior art exists provides a push bench pushes away oil cylinder frame clamping device.
In order to solve the technical problem, the utility model provides a push bench cylinder frame clamping device, which comprises a frame body, a cylinder, a positioning block, a clamping block and a locking pad, wherein the frame body is integrally in a U-shaped structure, and the cylinder is arranged on the frame body; the clamping block is internally provided with a locking pad, one side of the locking pad is contacted with the oil cylinder, and the other side of the locking pad is combined and tightly connected through a bolt and a nut; the contact surface of the clamping block and the oil cylinder is provided with an oil skid-proof pad; the oil cylinder is fixed on the frame body by the three-jaw clamping mechanism on the front panel and the rear panel and pushes the push bench to work.
The positioning blocks are welded on the front panel and the rear panel of the frame body.
The frame body is made of 40mm thick steel plates through welding.
The positioning block is made of a steel plate with the thickness of 40mm, and a threaded hole is drilled in the positioning block.
The anti-loosening pad is made of rubber, and a gap between the clamping block and the oil cylinder is made up.
Has the advantages that: the utility model discloses ensure the stability of propulsion process in the pipe pushing jack work progress, improve the efficiency of construction, it is showing the effect to have on solving propulsion cylinder skew phenomenon, the utility model relates to a simple structure, the equipment is convenient, can the propulsive stability of effective control hydro-cylinder, has improved the work efficiency of pipe pushing jack.
Drawings
Fig. 1 is a schematic structural view of the present invention;
fig. 2 is a schematic structural view of the three-jaw structure of the present invention.
In the figure: the oil cylinder locking device comprises a frame body 1, an oil cylinder 2, a positioning block 3, a clamping block 4, a bolt and nut combination 5 and a locking pad 6.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and examples.
The utility model provides a push bench push oil cylinder frame clamping device, which comprises a frame body 1, an oil cylinder 2, a positioning block 3, a clamping block 4 and a locking pad 6, wherein the whole frame body 1 is of a U-shaped structure, and the oil cylinder 2 is arranged on the frame body 1; the clamping block 4 is internally provided with a locking pad 6, one side of the locking pad is in contact with the oil cylinder 2, the other side of the locking pad is in compression connection through a bolt and nut combination 5, the bolt and nut combination 5 plays a role in fixing the oil cylinder through a positioning block and the clamping block, and a nut plays a role in locking; the contact surface of the clamping block 4 and the oil cylinder 2 is provided with an oil-adding anti-slip pad; the oil cylinder 2 is fixed on the frame body 1 by the three-jaw clamping mechanism on the front panel and the rear panel, and the oil cylinder 2 pushes the lower push bench to work; the relative effort is the biggest between hydro-cylinder 2 and the support body 1 this moment, the effect that the clamping device can effectually play to relax.
The positioning blocks 3 are welded on the front panel and the rear panel of the frame body 1.
The frame body 1 is made of 40mm thick steel plates through welding, oil cylinder mounting holes are punched, and stability test is well carried out; the bearing function is mainly played, the gravity action of the oil cylinder is borne, and the stability of the whole system is kept.
The positioning block 3 is made of a steel plate with the thickness of 40mm, and a threaded hole is drilled in the positioning block 3.
The anti-loosening pad 6 is made of rubber, so that a gap between the clamping block and the oil cylinder is made up, and contact friction is increased.
Because the anti-loosening pad 6 is padded, the friction force between the oil cylinder 2 and the clamping block 4 is greatly improved. The anti-loosening pad is added, so that the sliding or deviation phenomenon can be effectively solved.
The utility model discloses ensure the stability of propulsion process in the pipe pushing jack work progress, improve the efficiency of construction, it is showing the effect to have on solving propulsion cylinder skew phenomenon, the utility model relates to a simple structure, the equipment is convenient, can the propulsive stability of effective control hydro-cylinder, has improved the work efficiency of pipe pushing jack.
The above embodiments of the present invention are merely examples, not the only ones, and all changes within the scope of the present invention or the same range of the present invention are all surrounded by the present invention.
