Problems solved by technology

However, processing the sliding beam still increases the construction volume of the project, and when the stopper falls into the groove, it will cause the rail clamp to jump, making the sliding process not stable enough

Abstract

The invention relates to a self-adaptive steel channel rail clamping device. The self-adaptive steel channel rail clamping device comprises a pushing oil cylinder, counter-force frames, a pushing seat, tail seal plates, fixed bolts, compressed springs, wedge-shaped blocks, wedge block support plates, wedge block seats, a long pin and a hinge pin. The two sides of the pushing seat are each connected with one counter-force frame. The counter-force frames are each connected with one wedge block seat. The wedge-shaped blocks are embedded into dovetail grooves in the bottom ends of the wedge block seats. The fixed bolts penetrate through tail seams to be connected with the wedge-shaped blocks. The compressed springs are arranged between the fixed bolts and the wedge-shaped blocks. The wedge block support plates are connected with the bottom ends of the wedge block seats to be used for supporting the wedge-shaped blocks. The tail seal plates are connected with the tails of the wedge block seats to seal the dovetail grooves. A piston rod of the pushing oil cylinder is connected with the pushing seat. The self-adaptive steel channel rail clamping device has the characteristics of being low in system cost, good in moving stability, high in automation degree, simple to operate, good in clamping effect and the like.

Description

technical field [0001] The invention belongs to the technical field of rail clamping devices for hydraulic jacking and sliding construction, in particular to a rail clamping device, in particular to a self-locking channel steel rail clamping device. Background technique [0002] At present, with the rapid growth of my country's economy and the vigorous development of infrastructure construction, construction projects of large-space and long-span structures are increasing, and the installation of some large components puts forward higher requirements for construction technology. In the face of large grid and truss structures, the traditional high-altitude hoisting technology not only has a large construction area, high construction costs, and a long construction period, but also cannot meet the requirements of installation accuracy. Therefore, the construction technology of block assembly and cumulative slippage is gradually being promoted and used. [0003] Hydraulic jackin...
