Bridge construction device

Abstract

The invention discloses a bridge construction device comprising a clamping head, a base frame, a covering plate, two link mechanisms, a drive machine, two clamping and fixing claws, an iron attraction device and two fixed pieces. The clamping head is connected with a transport vehicle. The base frame is fixed to the left end of the clamping head and comprises a second empty cavity with a leftward port. A long strip groove is formed in the upper surface of the base frame. A first through cavity is formed in the portion, below the long strip groove, on the right side of the second empty cavity. A second through cavity in the vertical direction is formed in the portion, on the middle portion of the long strip groove, on the base frame. The covering plate is fixedly installed at the left end of the base frame and penetrates the second empty cavity rightwards. The iron attraction device is installed on the portion, on the right side of the first through cavity, on the upper surface of the base frame. The fixed pieces are fixed to the left side face of the covering plate. Pneumatic control is adopted for the device, operation is convenient and rapid, closing and locking of the clamping and fixing claws can be achieved through one drive machine, the manufacture cost is reduced, and meanwhile clamping is safe and reliable.

Description

technical field [0001] The invention relates to the field of bridges, in particular to bridge construction equipment. Background technique [0002] During the construction of the bridge, a large number of steel pipes are needed. Before, after or during the construction, the steel pipes often need to be transported. Nowadays, transport vehicles are usually used for transportation to effectively reduce manpower. The transport vehicles are handling the steel pipes When transporting, it needs to be clamped first. The traditional clamping device has a complex design structure, high manufacturing cost, and insufficient stability for clamping the steel tube. It is difficult to control the center of gravity of the steel tube. The risk of falling off in the clamping device. Therefore, there are certain safety hazards in the process of transporting the clamping device used by traditional transport vehicles, which will affect the progress of bridge construction.
