Description

Technical Field

[0001] The utility model relates to the technical field of monorail cranes, in particular to a light mobile monorail crane towing device. Background Art

[0002] Monorail cranes are a new type of underground coal mine transportation equipment and have been widely used in coal mines. Monorail crane beams are generally I-shaped steel with webs and flanges. Monorail crane beams can extend from the wellhead to multiple production work faces underground, and materials are transported by electric locomotives and diesel monorail cranes. At present, due to the need to classify and stack materials, materials can only be transported to the material yard by electric locomotives and diesel monorail cranes for classification and stacking, and then transported to the working face. However, the monorail crane transportation equipment is lagging behind, and sometimes multiple units share a monorail crane transport vehicle; and the monorail crane transport vehicle needs regular inspection and maintenance, and the monorail crane operator must be certified to work. In the absence of a transport vehicle or a professional operator, the monorail crane and the rail beam can only be idle, so that when the working face needs materials, they can only be transported manually, and the material yard and the working face are usually nearly 200 meters apart. Long-distance transportation will cause high labor intensity for personnel, which not only reduces the work progress, but also affects transportation safety. Utility Model Content

[0003] The technical problem to be solved by the utility model is how to reduce the labor intensity of personnel and ensure transportation safety.

Two groups of carrying plates are cross-hinged to form a roughly X-shaped structure. Rollers are arranged on the opposite sides of the top of each group of carrying plates, and limit blocks are arranged on the opposite sides of the carrying plates between the rollers and the carrying plates. A locking structure is arranged between the bottoms of the two groups of carrying plates. When the two groups of limit blocks are abutted, the rollers do not fit the belly plate of the monorail crane. When the locking structure is locked, the spacing between the rollers is smaller than the width of the flange plate.

[0006] The towing device is not only simple and light in structure and easy to install, but can also be hung and taken at any time. After the transportation work is completed, the locking structure can be opened and the towing device can be removed from the monorail crane by gently lifting it without affecting the operation of the monorail crane equipment. It can also transport goods within 100 kilograms, replacing manual handling procedures, thereby reducing labor intensity and ensuring transportation safety. At the same time, it also reduces the number of people required to transport materials, thereby reducing manpower and increasing efficiency, and improving work efficiency.

[0020] See also Figure 1 The present embodiment discloses a light mobile monorail crane towing device, comprising a carrying plate 1, a fixing pin 2, a roller 3, a limit block 4, a locking structure 5, a connecting rod 6, a shackle 7 and a pull rod 8. The cross-sectional shape of the carrying plate 1 is roughly Z-shaped, and two groups of carrying plates 1 are cross-hinged to form a roughly X-shaped structure. Specifically, the two groups of carrying plates 1 are hinged by the fixing pin 2 so that they can rotate along the hinge; rollers 3 are arranged on the opposite sides of the top of each group of carrying plates 1, and each roller 3 is respectively arranged on the flange plates 92 on both sides of the web 91 of the monorail crane 9, so as to realize the rolling of the rollers 3 on the monorail crane 9; in the present embodiment, the rollers 3 are made of bearings, and the bearing specifications are 6206-2RS, with an inner diameter of 30mm and an outer diameter of 60mm.

[0021] A limiting block 4 is symmetrically welded on the opposite side of the pallet board 1 between the roller 3 and the pallet board 1 at the hinge, and a locking structure 5 is arranged between the bottoms of the two groups of pallet boards 1. A connecting rod 6 is also hinged at the bottom of the pallet board 1, and a shackle 7 for lifting materials is connected between the two connecting rods 6. The pull rod 8 is used to pull the pallet board 1, so that the roller 3 on the top of the pallet board 1 rolls on the monorail crane 9.

[0022] When the two sets of limit blocks 4 are in contact, the roller 3 does not fit the web 91 of the monorail crane 9, which facilitates the rolling of the roller 3 on the monorail crane 9 and prevents the two rollers 3 from abutting and getting stuck on the web 91; when the locking structure 5 is locked, the distance between the rollers 3 is smaller than the width of the flange plate 91, preventing the roller 3 from falling off the monorail crane 9.

[0023] Furthermore, the locking structure 5 includes a bolt 51 and a locking nut 52. The screw rod 51 passes through the two groups of pallet boards 1 and is threadedly connected with the locking nut 52. The locking nut 52 is fixed on one group of pallet boards 1. Specifically, by rotating the screw rod 51 and threading the locking nut 52, the distance between the two ends of the bottom of the pallet board 1 is limited, and then the distance between the two ends of the top of the pallet board 1 is limited, so as to prevent the roller 3 from falling off the monorail 9, and when encountering the situation of misalignment of the track seam, it can ensure its smooth passage.

[0024] Furthermore, one end of the pull rod 8 is provided with a hook portion 81 capable of hooking the pallet 1 .

[0025] The working principle of this embodiment is:

[0026] First, turn the bolt 51 to disengage the bolt 51 from the locking nut 52, then pull apart the two sets of consignment rods 1, place the roller 3 on the flange plates 92 on both sides of the web 91, and then hang the material 10 on the shackle 7. Under the influence of gravity, the two ends of the bottom of the consignment rod 1 will automatically approach each other to achieve self-locking. At the same time, the two sets of limit blocks 4 abut against each other, so that the roller 3 does not fit the web 91 of the monorail crane 9, which facilitates the rolling of the roller 3 on the monorail crane 9; then turn the bolt 51 and the locking nut 52 to thread and lock them for protection and fixation, and then hook the consignment plate 1 through the hook portion 81 of the pull rod 8, and finally pull the pull rod 8 to carry out the towing work.

[0027] In this embodiment, the towing device structure is not only simple and light, easy to install, and can be hung at any time. After the transportation work is completed, the locking structure 5 can be opened and the towing device can be gently lifted to remove it from the monorail crane 9 without affecting the operation of the monorail crane equipment; and it can transport goods within 100 kilograms, replacing the manual handling process, thereby reducing the labor intensity of personnel, and eliminating the related risks caused by close contact between personnel and materials, ensuring transportation safety, and reducing the corresponding personnel for transporting materials, achieving the goal of reducing manpower and increasing efficiency, and improving work efficiency.
