An anti-rolling device for battery cars used in shield tunneling

Abstract

The invention discloses an anti-rolling device for battery cars used in shield tunneling construction, and belongs to the field of subway shield tunneling construction. An anti-rolling device for battery cars used in shield tunneling construction, comprising a track, a feeding car is arranged above the track, a screw groove is opened on the outer wall on the left side of the fixing plate, a screw rod is arranged in the screw groove, and the outer wall of the screw rod is symmetrically sleeved front and back There are two supporting feet, the front and rear ends of the fixed plate are provided with a limit slot, the inner wall on the right side of the limit slot is provided with a placement slot, the adjustment component is arranged in the placement slot, the movement plate is provided in the limit slot, and the bottom surface of the outer end of the movement plate is provided. There is an auxiliary clamping component. By setting the support feet, when the feeding car stops, the screw rod is rotated by turning the hand, so that the screw rod drives the threaded support feet to move. Since the outer wall of the screw rod is provided with external threads that rotate in the opposite direction, The two supporting feet are moved to both sides, so that the ends of the supporting feet are pressed against the inner wall of the track to generate frictional force, so that the stopped feeding cart can be kept stable and avoid slipping.

Description

technical field [0001] The invention relates to the field of subway shield construction, and more specifically relates to an anti-rolling device for battery cars used in shield construction. Background technique [0002] Subway shield tunneling is an important construction technology in urban subway construction, and it is a construction method for digging tunnels underground. It uses the subway shield machine to excavate underground, while preventing the soft ground excavation surface from collapsing or maintaining the stability of the excavation surface, while safely performing tunnel excavation and lining operations inside the machine. The construction process needs to excavate a shaft or a foundation pit at one end of a certain section of the tunnel, hoist the subway shield machine into the installation, and the subway shield machine starts to excavate from the wall opening of the shaft or foundation pit and advances along the designed hole line until To reach the end o...

Problems solved by technology

In subway shield construction, transportation in the tunnel is a very important link in the overall construction. During shield construction, the transportation in the tunnel mainly relies on battery locomotives as power to carry muck trucks, slurry cars, segment cars, etc. in the tunnel. In the process of shield excavation, when it is necessary to load the feed truck with soil and other materials, when the feed truck is located on the slope, due to the relatively simple structure of the existing feed truck, when the feed truck is on the slope, there will be In the case of a slipping car, the slipping car will cause harm to the equipment and personnel in the construction below. At the same time, because the existing feeding car is not convenient to control the weight of the material, the problem of overloading the feeding car will occur, which further increases the possibility of rolling away;

[0003] In the track anti-rolling car device in the existing patent technology, for example CN211281027U, the left and right double clamp arms are used to lock the vehicle under braking. The vehicle under braking is locked on the track, but the above-mentioned device can only perform single friction braking on the track, and its locking ability is limited. Immediately canceled, so that when the power of the transport vehicle is not fully utilized, it is still prone to a short-term car slipping phenomenon in the initial stage
