Description

Technical Field

[0001] The utility model belongs to the technical field of mine car insurance, in particular to a locking device for insurance facilities in an inclined tunnel. Background Art

[0002] The locking device for a tunnel safety facility is a critical piece of equipment in mine safety. It is primarily used to automatically or manually close mine tunnels in the event of an emergency (such as a gas explosion or fire), isolating the source of danger, preventing the spread of the accident, and ensuring the safety of miners. By monitoring the mine environment in real time, the device can quickly respond to danger and automatically trigger the locking device. With the advancement of automated and intelligent mining, traditional manual systems are gradually being replaced by intelligent locking devices with remote monitoring and adaptive capabilities. In the future, locking devices will become even more intelligent and integrated, further improving the efficiency of mine safety management.

[0003] Because underground trackways utilize numerous inclined tunnel safety devices to prevent vehicle runaway accidents, these devices are typically operated by pneumatically operated valves that are pushed open and closed by cylinders. The safety devices are opened in advance when a vehicle passes and then closed again afterward. Because the operating valves themselves lack pressure relief self-locking devices, there is a risk of air leakage at locations such as air duct interfaces. This creates a risk of the safety devices falling after they are opened, as their weight is greater than the cylinder thrust. Passing vehicles at this point could potentially cause a collision.

[0004] To this end, the utility model provides a locking device for an inclined lane safety facility. Utility Model Content

[0005] In order to make up for the shortcomings of the existing technology and solve the problem of falling risk caused by the deadweight being greater than the thrust of the cylinder, the utility model proposes a locking device for the inclined tunnel safety facility.

[0006] The technical solution adopted by the present invention to solve its technical problems is: the locking device of the inclined lane safety facility described in the present invention includes a second locking base, the bottom end of the second locking base is fixedly connected to the front and rear opposite fixing frames, the right side of the rear fixing frame is fixedly connected to a motor, a transmission assembly is provided on the left side of the motor, a limiting rod is provided at the front end of the transmission assembly, the limiting rod is rotatably connected to the fixing frame, a safety rod is fixedly connected to the outside of the limiting rod, a limiting assembly is provided on the left side of the safety rod, and a connecting assembly is provided on the left side of the limiting assembly.

[0007] Furthermore, the transmission assembly includes a worm, the motor output end is fixedly connected to the worm, the worm is rotatably connected to the rear fixed frame, the bottom end of the worm is meshed with a worm wheel, the worm wheel is rotatably connected to the fixed frame, and the fixed frame is rotatably connected to the limit rod.

[0008] Furthermore, the limiting assembly includes a card slot, and the left bottom end of the safety rod is provided with left and right opposite card slots, and the middle end inside the card slot is fixedly connected to the limiting block.

[0009] Furthermore, the connecting assembly includes a connecting seat, and the top of the connecting seat is fixedly connected with evenly distributed snap blocks, the snap blocks are snap-connected with the slots, and the snap blocks are snap-connected with the limit blocks.

[0010] Furthermore, a telescopic rod is fixedly connected to the left side of the connecting seat, a cylinder is provided on the outside of the middle end of the telescopic rod, and evenly distributed hydraulic rods are provided on the top of the cylinder. The top of the hydraulic rod is fixedly connected to the first locking base.

[0011] Furthermore, a rubber layer is provided on the inner side wall of the slot.

[0012] The beneficial effects of the utility model are as follows:

[0013] 1. The locking device for the inclined tunnel safety facility described in the utility model uses a worm to drive the worm wheel to rotate through a motor, and at the same time, the worm wheel drives the limit rod and the safety rod to rotate, so that the safety rod can rotate automatically. At the same time, the self-locking characteristics between the worm and the worm wheel can fix the angle of the safety rod, thereby preventing the weight of the safety rod from falling on the cylinder and the telescopic rod, and avoiding the risk of falling caused by the safety rod's own weight being greater than the cylinder thrust.

[0014] 2. The locking device for the inclined tunnel safety facility described in the utility model increases the connection stability between the telescopic rod and the safety rod by simultaneously engaging the engaging block on the connecting seat with the engaging slot and the limiting block, thereby avoiding the unstable connection between the connecting component and the limiting component. In addition, because the gravity of the safety rod is borne by the motor and the worm, there is only lateral stress between the connecting seat, the engaging block and the safety rod, the engaging slot and the limiting block, which will not affect other structures.
