Description
Technical Field
[0001] The utility model relates to the technical field of monorail cranes, in particular to a device for reducing the ineffective height of a monorail crane. Background Art
[0002] The monorail crane locomotive runs on a suspended monorail system and has high maneuverability and flexibility, and can adapt to the complex and changing underground environment. Although the monorail crane locomotive is relatively small in size, it has a large carrying capacity and can meet the transportation needs of heavy equipment in industrial fields such as coal mines.
[0003] At present, monorail cranes are commonly used as transportation tools in coal-producing tunnels in coal mining areas, including battery monorail cranes, diesel monorail cranes, and pneumatic monorail cranes to transport materials.
[0004] This technical solution still has at least the following drawbacks: During transportation, due to the limited height of the roadway, the monorail crane drags objects on the ground, posing a safety hazard. To eliminate this safety hazard, the lifting height of objects needs to be researched and resolved. Therefore, we propose a device to reduce the ineffective height of the monorail crane. Utility Model Content
[0005] The purpose of the utility model is to provide a device for reducing the ineffective height of a monorail crane, which solves the problem in the background art that during transportation, due to the limited height of the tunnel, the monorail crane drags on the ground when lifting objects, posing a safety hazard.
[0006] To achieve the above-mentioned purpose, the present utility model provides the following technical solutions: a device for reducing the invalid height of a monorail crane, comprising an H-beam main body, a saddle beam main body provided at the upper end of the H-beam main body, a track provided at the middle part of the upper end of the saddle beam main body, auxiliary beams provided on both sides of the saddle beam main body, a hanging point provided on the outer side of the auxiliary beam, an arc groove provided at the lower end of the auxiliary beam, strip grooves provided on both sides of the H-beam main body, a fixing strip provided in the inner cavity of the strip groove, and a screw rod provided in the inner cavity of the strip groove.
[0007] By adopting the above technical solution, the saddle-shaped saddle beam body is set on the H-beam body, and the two ends of the saddle beam body are tilted up, so that the height of the lifting point is increased, and then the height of the suspended object from the ground is increased. When adjustment is needed according to the application scenario, the screw rod is rotated, and the screw rod cooperates with the screw rod sleeve to drive the fixed bar to move outward, and the fixed bar drives the ball head to follow the movement. The ball head lifts the arc groove, and then lifts the auxiliary beam, so that the auxiliary beam rotates upward, and then the lifting point can be adaptively adjusted according to the application scenario, thereby protecting the safety of personnel and equipment and effectively avoiding accidents.
[0008] Optionally, a ball head is fixedly mounted on the upper end of the fixing bar, and the upper end of the ball head fits into the upper end of the inner cavity of the arc-shaped groove.
[0009] By adopting the above technical solution and arranging the ball head, the contact between the fixing strip and the arc groove can be made smooth.
[0010] Optionally, a screw sleeve is fixedly installed on the lower end of the fixing bar, and the screw rod is threadedly connected to the screw sleeve.
[0011] By adopting the above technical solution, the screw rod and the screw rod sleeve cooperate to drive the fixing bar to move, thereby adjusting the auxiliary beam.
[0012] Optionally, one end of the screw rod is rotatably connected to the inner cavity of the strip groove through a bearing.
[0013] By adopting the above technical solution, the stability of the screw rod rotation is ensured, thereby facilitating the rotation of the screw rod.
[0014] Optionally, the upper end of the auxiliary beam is rotatably connected to the upper end of the saddle beam body via a hinge.
[0015] By adopting the above technical solution and setting the hinge, the auxiliary beam can be easily rotated, thereby ensuring the stability of the auxiliary beam and the safety of the lifting.
[0016] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0017] The technical solution of the present application is to set up an H-beam main body, a saddle beam main body, a lifting point, a fixing bar, a ball head and a hinge. The saddle-shaped saddle beam main body set on the H-beam main body and the tilted structure at both ends of the saddle beam main body can increase the height of the lifting point and thus increase the height of the lifted object from the ground. The screw rod can also be rotated, and the screw rod cooperates with the screw rod sleeve to drive the fixing bar to move outward, and the fixing bar drives the ball head to follow the movement. The ball head lifts the arc groove and then lifts the auxiliary beam, causing the auxiliary beam to rotate upward. The lifting point can then be adaptively adjusted according to the application scenario, thereby protecting the safety of personnel and equipment and effectively avoiding accidents.
