Description

Technical Field

[0001] The utility model relates to the technical field of car stoppers, in particular to a monorail crane car stopper. Background Art

[0002] The small trailer that fixes cables and pipelines on the monorail crane in the auxiliary tunnel of the mining working face is easy to slide out of the slot from the monorail crane during the movement of the equipment train, which can easily cause accidents. Therefore, there are usually car stoppers at both ends of the monorail crane. When the trailer wheel slides to the end of the monorail crane, the car stopper can generate resistance to the trailer wheel to prevent the trailer from sliding out of the slot from the monorail crane.

[0003] However, the existing monorail crane car arrester is usually fixed with bolts, which makes the installation cumbersome and affects the installation efficiency, and is inconvenient for subsequent regular maintenance. In this regard, we propose a monorail crane car arrester to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a monorail crane car arrester to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a monorail crane car stopper, comprising:

[0006] A monorail crane is provided with a car stopper body, and a door-type mounting bracket is fixedly welded on the bottom wall of the car stopper body, and the door-type mounting bracket is engaged with the monorail crane. A fixing seat is fixedly welded at the end of the monorail crane, and a bidirectional screw rod is rotatably installed on the fixing seat. Guide rods are fixedly welded on both side walls of the fixing seat, and two movable plates are threadedly connected to the two movable plates, and the two movable plates are respectively slidably connected to the two guide rods through the through holes. A plurality of plug-in rods are fixedly welded on the opposite side walls of the two movable plates, and a plurality of through grooves compatible with the plug-in rods are provided on both side walls of the door-type mounting bracket, and a plurality of slots compatible with the plug-in rods are provided on the monorail crane.

[0007] Preferably, a plurality of positioning columns are fixedly welded on the monorail ceiling wall, a plurality of positioning slots are opened on the door-shaped mounting frame, and the positioning columns are adapted to the positioning slots.

[0008] Preferably, a through opening is opened on the fixing seat, and the bidirectional screw rod is fixedly installed with a limiting wheel on the surface of the inner cavity of the through opening, a stud is threadedly connected on the front side wall of the fixing seat, and a locking block is rotatably installed on one end of the stud close to the limiting wheel, and a guide column is fixedly welded on the locking block.

[0009] Preferably, a handwheel is fixedly mounted on one end of the bidirectional screw.

[0010] Preferably, the pressing surfaces of the limiting wheel and the locking block are both provided with anti-slip grooves.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] When the utility model is in use, the door-type mounting frame is positioned and placed on the monorail crane through the plug-in cooperation of the positioning column and the positioning groove, and then the hand wheel is turned forward to make the bidirectional screw rod rotate forward, thereby driving the two movable plates to move toward each other, driving the multiple plug-in rods to pass through the multiple through grooves and insert into the multiple slots respectively, thereby achieving the door-type mounting frame to be fixed on the monorail crane. When disassembling, it is only necessary to rotate the hand wheel in the reverse direction to make the multiple plug-in rods disengage from the through grooves, thereby achieving the rapid disassembly and assembly of the car blocker body, simple and convenient operation, and convenient subsequent regular maintenance;

[0013] The utility model discloses that after the car arrester body is installed, the stud can be moved backward on the fixing seat by rotating the stud forward, driving the locking block to press the limiting wheel, thereby locking the limiting wheel, avoiding the two-way screw rod from being easily loosened, which would cause the problem of loosening of the connecting rod. The provided positioning column and the positioning groove are plugged in and matched with each other, not only making it easy to position the door-type mounting frame when it is installed, but also strengthening the firmness of the connection between the door-type mounting frame and the monorail crane, so that when the car arrester body is subjected to lateral impact force, the door-type mounting frame will not deviate from the monorail crane, thereby improving the safety of use.

The positioning columns 11 are adapted to the positioning grooves 12. By plugging and fitting the positioning columns 11 and the positioning grooves 12, it is not only convenient to position the door-type mounting frame 3 when it is installed, but also the firmness of the connection between the door-type mounting frame 3 and the monorail crane 1 can be enhanced, so that when the car stopper body 2 is subjected to lateral impact force, the door-type mounting frame 3 will not deviate from the monorail crane 1, thereby improving the safety of use.

[0023] The fixing seat 4 is provided with a through opening 13, and the bidirectional screw rod 5 is fixedly installed with a limiting wheel 14 on the surface of the inner cavity of the through opening 13. A stud 15 is threadedly connected to the front side wall of the fixing seat 4, and a locking block 16 is rotatably installed on one end of the stud 15 close to the limiting wheel 14. A guide column 17 is fixedly welded on the locking block 16. When the stud 15 is rotated forward, the stud 15 can be moved backward on the fixing seat 4, driving the locking block 16 to press the limiting wheel 14, thereby locking the limiting wheel 14 to prevent the bidirectional screw rod 5 from loosening easily and causing the problem of loosening of the connecting rod 8.

[0025] The pressing surfaces of the limiting wheel 14 and the locking block 16 are both provided with anti-skid grooves, which can increase the friction force when the locking block 16 and the limiting wheel 14 are pressed together, thereby improving the anti-skid effect.

[0026] Working principle: When the utility model is in use, the door-type mounting frame 3 is positioned and placed on the monorail crane 1 through the plug-in cooperation of the positioning column 11 and the positioning groove 12, and then the hand wheel 18 is turned forward to make the bidirectional screw rod 5 rotate forward, thereby driving the two moving plates 7 to move toward each other, driving the multiple plug-in rods 8 to pass through the multiple through grooves 9 and insert into the multiple slots 10, so as to fix the door-type mounting frame 3 on the monorail crane 1. When disassembling, it is only necessary to rotate the hand wheel 18 in the reverse direction to make the multiple plug-in rods 8 disengage from the through grooves 9, thereby realizing the rapid disassembly and assembly of the car blocker body 2, which is simple and convenient to operate and convenient for subsequent regular maintenance After the car arrester body 2 is installed, the stud 15 can be rotated forward to move backward on the fixing seat 4, driving the locking block 16 to press the limiting wheel 14, thereby locking the limiting wheel 14, avoiding the two-way screw rod 5 from loosening easily and causing the plug-in rod 8 to loosen. The provided positioning column 11 is plugged into the positioning groove 12, which not only facilitates the positioning of the door-type mounting frame 3 during installation, but also strengthens the firmness of the connection between the door-type mounting frame 3 and the monorail crane 1, so that when the car arrester body 2 is subjected to lateral impact force, the door-type mounting frame 3 will not deviate from the monorail crane 1, thereby improving the safety of use.
