Description

Technical Field

[0001] The utility model belongs to the technical field of mine vehicle stabilization, and particularly relates to a mine vehicle stabilization anti-return device. Background Art

[0002] During mining operations, heavy lifting operations underground often require the use of a stabilizing mechanism. Because mine stabilizing mechanisms often lift heavy equipment or objects, the winch is subject to significant tension. Currently, electronic brakes are used to apply braking force by pressing friction plates against the brake surface. However, when subjected to high forces, electronic brakes are slow to stop. Repeated braking causes wear between the friction plates and the brake wheel, reducing braking effectiveness. This can cause the stabilizing mechanism's gears to reverse due to the pull of the winch, creating the risk of dropping the object. Summary of the Invention

[0003] In view of the above problems, the purpose of the present utility model is to provide a mine stabilizer and anti-return device to solve the problem that the current electronic brake is used to brake by driving the friction plate to press the surface of the brake wheel. When the force is large, the electronic brake stops slowly, and the friction plate and the brake wheel are repeatedly braked and worn, the braking effect decreases, and the stabilizer gear may be reversed due to the tension of the rope, which may cause the heavy objects to fall.

[0004] The transmission gear of the present invention is a gear selected from the group consisting of a gearbox and a gear train, and a gearbox is connected along the transmission gear of the present invention to form a gear train with a gearbox and a gearbox for transmitting the rotation of the transmission gear.

[0005] The beneficial effect of the utility model is that when the lever is turned upward, the lever drives the check hook to engage the outer side of the stabilizing gear. Under the engagement restriction of the check hook, the stabilizing gear cannot be reversed by the pulling force of the rope. Therefore, when lifting heavy objects, it is only necessary to engage the check hook into the outer side of the stabilizing gear to quickly stop the reverse rotation, thereby avoiding the risk of the heavy object falling due to the reverse rotation of the stabilizing gear.

[0006] In order to provide support for the handle;

[0007] As a further improvement of the above technical solution: a support block is provided in the middle of the side of the handle close to the stable frame, and the lower side of the support block is in contact with the upper side of the stable frame.

[0008] The beneficial effect of this improvement is that a support block is provided, and when the check hook is stuck on the stabilizing gear, the support block can provide support for the lever, thereby preventing the stabilizing gear from being too strong and causing the lever to break.

[0009] In order to facilitate the clamping of the check hook into the outside of the stabilizing gear or the detachment of the stabilizing gear;

[0010] As a further improvement of the above technical solution: a connecting rod is provided between the handles, one end of the connecting rod passes through the handle and is provided with a rotating sleeve for rotation, a hydraulic telescopic rod is provided on the side of the rotating sleeve close to the stabilizing gear, and the hydraulic telescopic rod is rotatably connected to the support seat.

[0011] The beneficial effect of this improvement is that the rotating sleeve is pulled by the output end of the hydraulic telescopic rod, the rotating sleeve drives the connecting rod, and the connecting rod drives the lever, thereby making it easy to clamp the check hook into the outside of the stabilizing gear or disengage the stabilizing gear.

[0012] In order to release the connection between the output end of the hydraulic telescopic rod and the rotating sleeve;

[0013] As a further improvement of the above technical solution: the output end of the hydraulic telescopic rod is plugged into the rotating sleeve, and a pin is provided on the upper side of the rotating sleeve, and the pin passes through the rotating sleeve and the output end of the hydraulic telescopic rod to the lower side.

[0014] The beneficial effect of this improvement is that the output end of the hydraulic telescopic rod is plugged into the rotating sleeve, and a pin is set to pass through the rotating sleeve and the output end of the hydraulic telescopic rod to the lower side to release the connection between the output end of the hydraulic telescopic rod and the rotating sleeve.

[0015] In order to facilitate the disassembly and replacement of the check hook;

[0016] As a further improvement of the above technical solution: the check hook includes a hook body, hook teeth and a connecting groove, the upper side of the hook body is provided with a connecting groove, the inner side of the connecting groove is threaded with a bolt, and the bolt passes through the hook body and is threadedly connected to the handle.

[0017] The beneficial effect of this improvement is that bolts are provided to fix the hook body and the lever, making it easy to disassemble and replace the check hook.

[0018] In order to facilitate the quick alignment of the hook teeth and their insertion into the gear groove of the stabilizing gear;

[0019] As a further improvement of the above technical solution: the hook teeth are hinged to the hook body, and the hook body and the hook teeth rotate slightly.

[0020] The beneficial effect of this improvement is that it is not easy for the check hook to accurately clamp the stabilizing gear when it contacts the stabilizing gear. The hook teeth are hinged to the hook body. The hook body and the hook teeth rotate slightly. When they contact the outside of the stabilizing gear, the hook teeth can move slightly according to the position of the gear groove of the stabilizing gear, which makes it easy for the hook teeth to quickly align and clamp into the gear groove of the stabilizing gear.

[0021] In order to facilitate the quick removal of the anti-return mechanism from the stable frame;

[0022] As a further improvement of the above technical solution: a clamping groove is provided on the side of the stable frame corresponding to the rotating seat, a clamping block is provided inside the clamping groove for plugging and clamping, and the clamping block is fixedly connected to the rotating seat.

[0023] The beneficial effect of this improvement is that the provision of a clamping block for plugging and clamping with the clamping slot facilitates quick disassembly of the anti-return mechanism from the vehicle stabilizing frame.

[0024] The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art. BRIEF DESCRIPTION OF THE DRAWINGS
