Ballastless track base plate post-cast strip breaking device, system and method

Abstract

The invention discloses a ballastless track base plate post-cast strip breaking device, system and method, and relates to the technical field of concrete breaking equipment. The device comprises a lateral locking mechanism which is fixed on a rack. The rack is also fixedly provided with a guide shaft, and the rack is further provided with a driving mechanism which slides along the guide shaft anda lifting mechanism which enables the driving mechanism to move up and down. The output end of the driving mechanism is provided with a hollow shaft, and the input end of the hollow shaft is is connected with a rotary joint; and the output end of the hollow shaft is further fixedly provided with a high-pressure spray head, wherein the high-pressure spray head communicates with the interior of thehollow shaft. According to the ballastless track base plate post-cast strip breaking device, system and method, a post-cast strip can be broken without using an oppositely-cover plate, and during theconstruction, a reinforcement cage structure can be maximally retained, so that a concrete structure is removed without damaging reinforcing steel bar, and accordingly the breaking speed of the post-cast strip is improved by 20 times-50 times.

Description

technical field [0001] The invention relates to the technical field of concrete demolition equipment, in particular to a demolition device, a demolition system and a demolition method for a post-cast belt of a ballastless track base plate. Background technique [0002] Since the ballastless track on the bridge was laid on the Beijing-Tianjin Intercity Railway, because of its stability and comfort during high-speed operation, it has been successively laid on the Beijing-Shanghai High-speed Railway, Beijing-Wuhan High-speed Railway, Shanghai-Hangzhou Passenger Dedicated Line, and Nanjing-Hangzhou Passenger Dedicated Line , Hebang Passenger Dedicated Line, etc., have been widely used. The ballastless track system on the bridge is composed of steel rails, fasteners, track plates, mortar adjustment layers, base plates, two cloth and one film sliding layers, high-strength extruded plastic plates, and lateral stops. Friction plates, End thorns and transition plates. [0003] In o...

AI Technical Summary

Problems solved by technology

Although the thorough repair method of removing the board can completely repair the fractured cracks of the post-cast belt and restore it to the original construction state, but this repair method has complicated procedures, great impact on traffic and long repair construction time. It takes 90 days to complete the single-line repair construction. 1 skylight period, 18 skylight periods are required to complete the double-track construction, which takes a long time; while the reinforcement repair method of the cross-connection side width of the base plate is relatively simple, and the damage to the main structure of the existing track is small, and the interference to the traffic is also small. Smaller, its disadvantage is that pouring a large area of ​​integral concrete will produce shrinkage cracks, and the contact between the old and new concrete surfaces will also cause cracks. 10 skylight periods
