An automatic reset device for a caisson transport pusher

Abstract

The invention discloses an automatic resetting device for a caisson launching push instrument, belonging to the field of caisson launching equipment. The automatic resetting device comprises a pushing rail clamping body, wherein an ear plate is arranged on one side of the pushing rail clamping body, a slideway is arranged at the bottom of the pushing rail clamping body, and racks are arranged in the slideway. The automatic resetting device further comprises an arc-shaped bent plate arranged on the pushing rail clamping body, plain shafts arranged on the tail end of the racks, and reset springs arranged on the plain shafts, wherein two bottom supporting plates are arranged at the bottom of the pushing rail clamping body, the slideway is arranged between the two bottom supporting plates, the racks are arranged on the bottom supporting plates on the two sides of the slideway, one ends of the plain shafts are fixedly arranged on the tail ends of the racks, and the other ends of the plain shafts are fixedly arranged on the arc-shaped bent plate. According to the automatic resetting device, people does not need to hold the racks for inserting when the push instrument is in working, so that the labor force is saved and the safety is ensured; the pushing of the racks to be inserted in the push instrument is controlled by the rear springs, the sizes are fixed, the strokes of the racks on the two sides are uniform, and the stress inside the slidway of the rail clamping device is guaranteed to be balanced; and the labor participation is avoided in pushing operation, continuous working can be achieved and the efficiency can be improved.

Description

technical field [0001] The invention relates to an automatic reset device for a caisson transport pusher, which belongs to the field of caisson transport equipment. Background technique [0002] The racks on both sides of the rail gripper of the existing caisson transporting trolley are manually operated, and the worker's sense of responsibility and operating skills have a great impact on the use of the equipment. Often, the length of the two racks is different when inserted. The size of the contact surface with the internal slideway is quite different, which leads to the failure of the rail clamp and even damage to the rail clamp, which seriously affects the construction efficiency and construction quality. Contents of the invention [0003] Aiming at the above-mentioned problems in the prior art, the present invention provides an automatic reset device for the caisson delivery pusher, which reduces irregular operations by personnel and avoids abnormal wear or even damage...
