Description

Technical Field

[0001] This utility model relates to the field of anti-slip support device for tunnel lining trolley, and more specifically, to an anti-slip support device for tunnel lining trolley. Background Technology

[0002] In conventional methods of fixing secondary lining trolleys in tunnels, they are typically secured by inclined support legs. This involves creating a depression by breaking through the existing inverted arch road surface, placing the support legs into the depression, or directly driving reinforcing bars into the inverted arch road surface so that the bottom of the support legs and the reinforcing bars bear linear stress. For example, in traditional technology, a safety-type inclined shaft lining trolley disclosed in Chinese utility model patent CN203248167U has diagonal braces at intervals at the front end of the trolley gantry, with the upper end hinged to the trolley gantry and the lower end secured in a ground-level pit. While this type of support structure is suitable for tunnels with gentle slopes, it is insufficient in inclined shaft tunnels with steep slopes, leading to instability and significant safety hazards.

[0003] Furthermore, based on existing technology patents, such as the authorized publication number CN222823250U, this utility model provides an anti-slip support device for a secondary lining trolley in an inclined shaft tunnel, including an anti-slip support base plate, a hinge seat, and a support member. The anti-slip support base plate includes a bottom surface and a top surface arranged opposite to each other, and barbs are evenly arranged on the bottom surface of the anti-slip support base plate. The hinge seat is fixed to the top surface of the anti-slip support base plate. The support member includes a first end and a second end arranged opposite to each other. The first end of the support member is used to connect a secondary lining trolley in an inclined shaft tunnel, and the second end of the support member is connected to the hinge seat so as to be rotatably connected to the anti-slip support base plate plate via the hinge seat, which can improve the stability of the secondary lining trolley support.

[0004] In the aforementioned prior art, a barb structure is provided on the lower surface of the anti-slip support base plate. This base plate is a square plate structure with numerous barbs on the bottom. Due to the dense barbs, when tilted for support, the large number of barbs makes it difficult to stably insert into the ground for support, and the plate is prone to sliding. Furthermore, the support rods are connected by threads, resulting in poor stability of the support structure after adjustment. Utility Model Content
