[0024] Please refer to Figures 1 to 2 The simple and rapid braking tunnel cloth hanging trolley device shown in an embodiment of the application comprises a trolley body 10, moving wheels 20 and a braking assembly 30. An operation table is formed on the trolley body 10. A plurality of moving wheels 20 are arranged at the bottom of the trolley body 10.

[0025] The brake assembly 30 comprises a brake member 31 movably connected to the trolley body 10 and located at one side of the moving direction of the moving wheels 20, and a locking member 32 inserted into the trolley body 10, the brake member 31 has a first position abutting the moving wheels 20 and the ground to lock the moving wheels 20, and a second position away from the moving wheels 20 and the ground to unlock the moving wheels 20, and the locking member 32 is configured to lock the brake member 31 when the brake member 31 is in the first position and the second position respectively.

[0026] In an embodiment, an L-shaped movable slot 11 is provided through the trolley body 10, one end of the brake member 31 is movably connected in the L-shaped movable slot 11, and the two ends of the L-shaped movable slot 11 are configured as the first position and the second position respectively. The L-shaped movable slot 11 is horizontally arranged at one side of the moving direction of the moving wheels 20, and the second position is higher than the first position, and the brake member 31 rotates by 90° in the process of moving from the first position to the second position, so that the brake member 31 is suspended in the horizontal direction in front of the moving wheels 20 in the moving direction when unlocked, avoiding the brake member 31 from colliding with the ground and affecting the movement of the trolley.

[0027] In an embodiment, the brake member 31 is a triangular plate, and the brake surface abutting the moving wheels 20 is configured as a circular arc surface matching the shape of the moving wheels 20, so that the contact area between the brake member 31 and the moving wheels 20 is larger and the braking effect is better, and the actuating surface abutting the ground is a plane, which is convenient for abutting the ground and beneficial to braking.

[0028] In an embodiment, the locking member 32 is a locking rod, locking holes are provided at the two ends close to the L-shaped movable slot 11, and the locking rod is inserted into the locking holes to clamp the brake member 31 at the two ends of the L-shaped movable slot 11. The locking rod is a steel bar, which is inserted and pulled out to unlock and lock the brake member 31, and pins are installed at the two ends of the steel bar for fixation to prevent the steel bar from falling off, which is easier to operate and has higher locking effect.

[0029] In an embodiment, the brake member 31 comprises a brake end and a connecting end, a connecting slot is formed through the connecting end, and the connecting slot is movably connected with the L-shaped movable slot 11. In this way, the brake member 31 wraps the end of the trolley body 10 in the middle, and in the braking process, the connecting end on both sides of the end of the trolley body 10 of the brake member 31 abuts against the locking rod, improving the strength of the locking member 32 and the stability of braking.

[0030] In an embodiment, the moving wheels 20 are provided with four groups, and the brake members 31 are provided with four groups and arranged at one side away from the trolley body 10 of the moving wheels 20. By arranging the brake members 31 on the outside of the moving wheels 20, the brake members 31 can provide stable braking effect in the advancing or retreating direction of the moving wheels 20.

[0031] In an embodiment, the trolley body 10 comprises a trolley frame and a plurality of support plates arranged on the trolley frame, the plurality of support plates are arranged in a stepped manner on both sides of the trolley frame to form an operation table. The top of the trolley frame is provided with a convex support plate. The convex support plate and the support plates together form an operation table conforming to the shape of the tunnel, which facilitates the cloth hanging construction of the construction personnel.

[0032] The application sets the brake assembly on one side of the moving direction of the moving wheel. When the brake is applied, the brake member is moved to the first position, and the brake member is in contact with the ground and the moving wheel to limit the rotation of the moving wheel. Then, the position of the brake member is locked by the locking member, thereby realizing the braking of the trolley body. When the brake is unlocked, the brake member is moved to the second position, and the brake member is away from the ground and the moving wheel, thereby facilitating the movement of the trolley. The brake member is locked at the second position by the locking member, thereby avoiding the interference of the brake member with the normal movement of the trolley. The structure is simple and convenient to operate, and solves the problem that the dust in the tunnel affects the traditional trolley oil pressure brake system.
