Description

Technical Field

[0001] The utility model relates to the technical field of coal mine electromechanical transportation, in particular to a connection structure. Background Art

[0002] Coal mine electromechanical transportation plays an important role in coal mine safety. It can improve production efficiency, ensure production safety, improve equipment operation and maintenance efficiency, and reduce transportation costs. The crawler transport frame is one of the common equipment for safe transportation in coal mines. When transporting over long distances, it is often necessary to connect and assemble multiple sets of transport frames. How to avoid the impact of the terrain of the coal mine environment on the assembly connection, and how to quickly realize the rapid disassembly and assembly between two sets of transport frames are currently problems that need to be solved urgently.

[0003] After searching, the announcement number CN218808792U discloses a coal mine electromechanical transport connection structure, including a No. 1 transport frame and a No. 2 transport frame, the No. 1 transport frame is provided with a No. 1 conveyor belt on the upper end, the No. 2 transport frame is provided with a No. 2 conveyor belt on the upper end, the front right and rear right parts of the No. 1 transport frame and the front left and rear left parts of the No. 2 transport frame are fixedly connected with fixed blocks, the middle of the right ends of the two fixed blocks on the left side and the middle of the left ends of the two fixed blocks on the right side are provided with positioning grooves, the front right and rear right parts of the No. 1 transport frame and the front left and rear left parts of the No. 2 transport frame are provided with card slots. The coal mine electromechanical transport connection structure described in this utility model can enable the two coal mine electromechanical transport equipment to be positioned on the same horizontal line and preliminarily connected during the connection process, avoid the displacement during the connection process that affects the transportation of the coal mine, and improve the overall connection stability.

[0004] The above-mentioned electromechanical transportation connection structure for coal mines uses the positioning block to be inserted into the positioning groove to complete the preliminary installation of the No. 1 transport frame and the No. 2 transport frame, and then rotates the handle in sequence to drive the screw to rotate to complete the fixing of the No. 1 transport frame and the No. 2 transport frame. This design requires rotating the handle in sequence to complete the tightening, which will make the overall disassembly and assembly process time-consuming. At the same time, the No. 1 transport frame and the No. 2 transport frame need to maintain a horizontal state when the positioning block and the positioning groove are connected. However, due to the uneven terrain of the coal mine environment, there will often be an angle deviation between the positioning block and the positioning groove, which will cause the No. 1 transport frame and the No. 2 transport frame to be unable to be connected and assembled in a non-horizontal state.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

This design solves the problem that the existing technology requires the rotation of the rotary rod in sequence to complete the tightening, which makes the overall disassembly and assembly process time-consuming. At the same time, the No. 1 transport frame and the No. 2 transport frame need to maintain a horizontal state when the positioning block and the positioning groove are engaged. However, due to the uneven terrain of the coal mine environment, there is often an angle deviation between the positioning block and the positioning groove, which leads to the problem that the No. 1 transport frame and the No. 2 transport frame cannot be connected and assembled in a non-horizontal state.

[0026] See also Figure 4 and Figure 5The first connecting component 3 also includes a rail groove 311, which is opened on the side of the first side seat 31. The first connecting component 3 also includes a forward and reverse motor 32, which is fixedly installed on the outside of the first side seat 31. The output end of the forward and reverse motor 32 is fixedly connected to the bidirectional threaded rod 321. The bidirectional threaded rod 321 is rotated and connected to the rail groove 311 through the forward and reverse motor 32. The first connecting component 3 also includes two groups of slides 33 symmetrically threadedly connected to the opposite threads on both sides of the bidirectional threaded rod 321. Each slide 33 is fixedly connected to each conical seat 34. The first connecting component 3 also includes an anti-slip pad 34 1. The anti-slip pad 341 is annular and fixedly connected to the outside of the conical seat 34. By starting the forward and reverse motor 32, the bidirectional threaded rod 321 is driven to rotate, so that the sliding seat 33 threadedly connected to the opposite threads on both sides of the bidirectional threaded rod 321 moves synchronously backward until the conical seat 34 is engaged with the bearing 43. The above can complete the assembly connection of the first transport mechanism 1 and the second transport mechanism 2 through the first connecting component 3 and the second connecting component 4. In this design, the anti-slip pad 341 is provided on the outside of the conical seat 34 and the anti-slip ring pad 431 is provided on the inside of the bearing 43 to increase the contact friction between the two.

[0027] See also Figure 4 The first connecting component 3 also includes a limit seat 35. Two sets of limit seats 35 are symmetrically fixedly connected in the rail groove 311. The limit seat 35 can prevent the slide 33 from falling off when moving inward on the outside of the bidirectional threaded rod 321.

[0028] See also Figure 5 The second connecting component 4 also includes a side support 42, which is symmetrically fixedly connected to the side of the second side seat 41. The side support 42 is fixedly connected to the outer ring of the bearing 43, and the inner ring of the bearing 43 is fixedly connected to the anti-slip ring pad 431.

[0029] See also Figure 6 An auxiliary delivery component 5 is provided on the top of the first side seat 31 and the second side seat 41. The auxiliary delivery component 5 includes an upper top seat 51. The two groups of upper top seats 51 are fixedly connected to the top of the first side seat 31 and the second side seat 41 respectively. The connection between the two can be completed by aligning the inner ring of the bearing 43 with the conical seat 34 and through the forward and reverse motor 32.

[0030] See also Figure 6 The auxiliary transport component 5 also includes a rotating column 521, which is rotatably connected to the slot on the top of the upper seat 51. The auxiliary transport component 5 also includes a roller 52, which is fixedly connected to the outside of the rotating column 521. By providing an upper seat 51 on the top of the first side seat 31 and the top of the second side seat 41, and providing a rotatable rotating column 521 and a roller 52 on the top of the upper seat 51, the transportation of objects can be prevented from being stuck in the gap after the first transport mechanism 1 and the second transport mechanism 2 are connected.

[0031] The working principle and use process of this utility model are as follows:

[0032] After aligning the orientations of the second connecting assembly 4 on the side of the first transport mechanism 1 with the first connecting assembly 3 on the side of the second transport mechanism 2, align the conical seat 34 with the bearing 43, then start the forward and reverse motor 32 to drive the bidirectional threaded rod 321 to rotate, thereby causing the sliding seat 33 threadedly connected to the opposite threads on both sides of the bidirectional threaded rod 321 to move synchronously in the opposite directions until the conical seat 34 is engaged with the bearing 43, thus completing the connection and assembly work between the first transport mechanism 1 and the second transport mechanism 2;

[0033] Similarly, starting the forward and reverse motor 32 in reverse direction can complete the separation of the first transport mechanism 1 and the second transport mechanism 2;

[0034] Since the conical seat 34 is clamped on the bearing 43 and can rotate with the inner ring of the bearing 43, the first transport mechanism 1 and the second transport mechanism 2 can be tilted at a certain relative angle after being firmly connected by the first connecting assembly 3 and the second connecting assembly 4, thereby improving the applicability of the entire device in the uneven terrain environment of the coal mine.

[0035] When an object is transported between the first transport mechanism 1 and the second transport mechanism 2 and passes through the gap at the connection between the first transport mechanism 1 and the second transport mechanism 2, the rotating column 521 and the roller 52 located on the top of the upper top seat 51 will rotate when they contact the object. This design can make the overall transportation process smoother.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
