Description

Technical Field

[0001] The utility model relates to the technical field of shaft car stops, and particularly relates to a movable car stop device for underground mine shafts. Background Art

[0002] A shaft refers to a roadway for discharging ore from top to bottom by its own weight, and it is widely used in mines developed by adits or vertical shafts. A grizzly is installed at the shaft mouth, which is used to screen the ore entering the shaft to prevent oversized ore from entering the shaft and causing blockage, and at the same time, it can also prevent mine workers or equipment from accidentally falling into the shaft and causing danger.

[0003] Due to the large size of the shaft grizzly, the phenomenon of the shaft grizzly jamming the tires of the load-haul-dump (LHD) vehicle will occur during the ore dumping process, which is extremely dangerous. The previous solution was to set a corresponding car stop for the LHD vehicle at the ore dumping port of the shaft. The car stop is used to block the tires of the LHD vehicle to prevent the phenomenon of the shaft grizzly jamming the tires. Generally, the car stop is completely fixed at the ore dumping port and is not easy to be disassembled. When the shaft is blocked, it is difficult to quickly disassemble the car stop, which seriously hinders the work of solving the blockage.

[0004] The Chinese utility model patent with the patent application number CN202223500738.3 records a movable car stop device for underground mine shafts. Through two set positioning grooves, the positioning grooves are fixedly connected to the rocks on both sides of the ore dumping port of the shaft, and the car stop is fixed to the positioning grooves through locking parts, which can not only realize the stable fixation of the car stop to prevent the car stop from being knocked away, but also realize the detachable installation of the car stop, which is convenient for quickly transferring the car stop when it is not needed, thus further saving resources. However, when the above car stop device is impacted by the wheels of the LHD vehicle, the impact force is mainly borne by the positioning grooves, the baffle and the bolts, which easily causes the baffle and the bolts to deform and brings difficulties to the subsequent disassembly of the two, and then leads to the car stop cannot be quickly disassembled, reducing the convenience and practicality of the car stop. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a movable car stop device for underground mine shafts to solve the problem that in the existing car stop device, after being impacted by the loading vehicle, the detachable connecting parts bear a large impact force and are prone to deformation, which further leads to difficult disassembly of the connecting parts, and then the car stop cannot be quickly disassembled, reducing the convenience and practicality of the car stop as mentioned in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical scheme: A movable car stop device for underground mine shafts includes two fixed channel steels, and also includes two support components symmetrically hinged in the notches of the two fixed channel steels. A car stop is detachably connected to the two support components, and also includes a pre-buried fixing component and a connecting component;

[0007] The connecting component is used to detachably and fixedly connect two support components and a pre-embedded fixing component together to improve the impact resistance.

[0008] The support component includes a fixing plate, the fixing plate is hinged in the notch of the fixed channel steel, and the car stop is detachably connected to the front surface of the fixing plate.

[0009] Preferably, the support component further includes a plurality of right-angled trapezoidal support plates fixedly connected to the front surface of the fixing plate at equal intervals in the horizontal direction. The car stop is detachably and fixedly connected to the inclined waist surface of the support plate. The support component further includes a plurality of triangular support angle steels fixedly connected to the back surface of the support plate at equal intervals in the horizontal direction. The advantage of such a setting is that, through the cooperation of the support angle steel, the fixing plate and the right-angled trapezoidal support plate, reliable support can be provided for the car stop, effectively preventing the wheels of the forklift from getting too close to the chute grizzly and being stuck by the sieve holes, and preventing the hinge joint between the fixing plate and the fixed channel steel from being deformed due to excessive impact when the car stop is impacted, ensuring that the car stop can be smoothly and quickly disassembled when needed, and effectively improving the convenience and practicality of the car stop device.

[0010] Preferably, the pre-embedded fixing component includes a fixing bar pre-embedded in the soil or rock layer. The fixing bar is located directly below the support plate. A plurality of insertion rods are fixedly connected to the bottom of the fixing bar in sequence from left to right. The plurality of support plates are detachably and fixedly connected to the fixing bar through the connecting component. The advantage of such a setting is that by detachably and fixedly connecting the support plate and the fixing bar pre-embedded in the soil or rock layer, the support strength of the car stop can be further improved, the impact force on the hinge joint between the fixing plate and the fixed channel steel can be further reduced, ensuring that the car stop can be smoothly and quickly disassembled when needed, and further improving the convenience and practicality of the car stop device.

[0011] Preferably, the pre-embedded fixing component further includes two groups of hook bars symmetrically fixedly connected to the front and back sides of the insertion rods. The number of each group of hook bars is several and they are fixedly connected to the side of the insertion rod at equal intervals from top to bottom. The included angle between the hook bar and the insertion rod is less than ninety degrees. The advantage of such a setting is that it can improve the connection strength and stability of the fixing bar in the soil or rock layer, thereby reliably providing reliable support for the car stop and effectively improving the reliability of the device.

[0012] Preferably, the connecting component includes a through cavity formed in the left side surface of the support plate. A limiting rod is movably inserted into the bottom wall of the through cavity. A cross plate is fixedly connected between the tops of the plurality of limiting rods. The connecting component further includes a plurality of limiting holes formed at equal intervals from left to right on the top of the fixing strip. The bottom ends of the plurality of limiting rods respectively penetrate through the bottom of the plurality of support plates and are respectively movably inserted into the plurality of limiting holes. The cross plate is fixedly connected to the top of the fixing strip through a first bolt. The advantage of such a setting is that by movably inserting the plurality of limiting rods penetrating through the bottom of the support plate into the plurality of limiting holes on the top of the fixing strip, it is ensured that the plurality of support plates can be more firmly connected to the fixing strip, ensuring the connection strength between the embedded fixing component and the support component, and improving the support strength and stability of the car bumper.

In the present utility model, through the provided two groups of hook rods, the connection strength and stability of the fixing strip in the soil or rock layer can be improved, so as to reliably provide reliable support for the car bumper, effectively improving the reliability of the device.
