Description

Technical Field

[0001] This utility model belongs to the field of monorail locomotive lifting equipment, and in particular relates to a mining monorail locomotive lifting device. Background Technology

[0002] In mining transportation, a combination of monorail and underground rail is often used for coal transport. Materials are loaded onto mining monorail locomotives and then lifted for transport using hoisting devices. Currently, the common practice is to directly fix the lifting chains to the locomotive, or to use two lifting chains distributed on both sides of the locomotive, with the ends of the two chains fixed together, and then lift the locomotive by using a lifting beam. If either of these methods is not securely fixed, the locomotive can easily detach from the lifting chains during the lifting process, affecting transportation efficiency and safety. Utility Model Content

[0024] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] As shown in the figure, a lifting device for a mining monorail crane includes a lifting beam 1. The bottom of the lifting beam 1 is provided with a first connecting seat 2 and a second connecting seat 3, which can move horizontally along the length of the lifting beam 1. The first connecting seat 2 contains two rotatable I-beams, each with a lifting chain 4 wound around it. The bottom of the second connecting seat 3 has connecting lugs 12 corresponding to each I-beam, and the end of each lifting chain 4 is hooked to the corresponding connecting lug 12. In this embodiment, two connecting seats are provided at the bottom of the lifting beam 1. The horizontal position of the lifting chain 4 is adjusted by adjusting the horizontal position of the two connecting seats. Simultaneously, the lifting chain 4 is designed with a retractable structure, which is more conducive to lifting and connecting the mining monorail crane. The lifting chain 4 passes through the bottom of the mining monorail crane and its end is connected to the connecting lug 12.

[0026] The lifting beam 1 is a tubular structure with an open bottom and sealed ends. Inside the lifting beam 1, along its length, are a bidirectional screw 5 and a guide rod 6. A first connecting seat 2 and a second connecting seat 3 are both connected between the bidirectional screw 5 and the guide rod 6. A first motor 10 is fixedly connected to one end of the lifting beam 1, and the output shaft of the first motor 10 is fixedly connected to one end of the bidirectional screw 5. In this embodiment, the other end of the bidirectional screw 5 is connected to the other end of the lifting beam 1 via a bearing. The guide rod 6 is fixed between the two ends. The first motor 10 drives the bidirectional screw 5 to rotate, thereby causing the first connecting seat 2 and the second connecting seat 3 to move towards or away from each other.

[0027] The first connecting seat 2 includes a first connecting block 201 and a connecting box 202 fixed to the bottom of the first connecting block 201. The first connecting block 201 is connected to the bidirectional screw 5 and the guide rod 6. The bottom of the connecting box 202 is open. Inside the connecting box 202, two connecting shafts 7 are arranged side by side, parallel to the lifting beam 1. Rotating wheels 8 are fixed to both connecting shafts 7. A belt 9 is connected between the two rotating wheels 8. A second motor 11 is fixed to one of the connecting shafts 7 on the outside of the connecting box 202. The output shaft of the second motor 11 is fixed to one end of the corresponding connecting shaft 7. An I-beam is fixed to the corresponding connecting shaft 7. In this embodiment, the other end of the connecting shaft 7 connected to the second motor 11 and both ends of the other connecting shaft 7 are connected to the connecting box 202 through bearings. Alternatively, a connecting shaft 7 can be horizontally installed within the connecting box 202, perpendicular to the lifting beam 1. A second motor 11 is located on the outer side of the connecting box 202 corresponding to the connecting shaft 7. The output shaft of the second motor 11 is fixedly connected to the connecting shaft 7. Two I-beams, arranged front and rear, are fixedly mounted on the connecting shaft 7. Both of these connecting shaft 7 configurations are acceptable. To ensure the I-beams are spaced apart and rotate synchronously, two I-beams are spaced apart in the horizontal direction perpendicular to the lifting beam 1. This ensures that the two lifting chains 4 are spaced a certain distance apart, allowing for a more stable lifting of the mining monorail locomotive when the two lifting chains 4 are used.

[0028] Multiple first reinforcing ribs 203 are provided between the top of the first connecting block 201 and the top of the connecting box 202.

[0029] The second connecting seat 3 includes a second connecting block 301 and a connecting frame 302 fixed to the bottom of the second connecting block 301. The second connecting block 301 is connected to the bidirectional screw 5 and the guide rod 6. The connecting frame 302 is an I-beam that is horizontal and perpendicular to the lifting beam 1. The connecting lug 12 is fixed to the bottom of the lower flange of the I-beam.

[0030] The connecting lug 12 is a U-bolt structure, and the top two ends of the connecting lug 12 pass through the lower flange of the I-beam and are screwed with double nuts 13.

[0031] Multiple second reinforcing ribs 303 are provided between the top of the second connecting block 301 and the connecting frame 302.

[0032] Multiple lifting lugs 101 are evenly fixed to the top of the lifting beam 1.

[0033] The end of the chain 4 is connected to a hook 401, which is hooked to the connecting lug 12.

[0034] The working process of this embodiment is as follows:

[0035] First, the first motor 10 drives the bidirectional screw 5 to rotate, thereby causing the first connecting seat 2 and the second connecting seat 3 to move in opposite directions. Then, the second motor 11 drives the connecting shaft 7 to rotate, thereby lowering the lifting chain 4. The lifting chain 4 is then passed through the bottom of the mining monorail crane and the hook 401 is connected to the connecting lug 12. The first motor 10 then moves the first connecting seat 2 and the second connecting seat 3 towards each other by a certain distance, and the second motor 11 tightens the excess lifting chain 4, so as to maximize the contact area between the lifting chain 4 and the mining monorail crane, ensuring that the mining monorail crane is more stable after lifting.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
