Description

Technical Field

[0001] The utility model belongs to the technical field of load-bearing frames, and in particular relates to a coal mine electromechanical transport load-bearing frame. Background Art

[0002] Coal mine electromechanical transportation device refers to a device that uses motor cables to transport coal in the mine. It can transport coal in the mine along the track to the outside of the mine, reducing manual handling and improving work efficiency. When transporting coal, most of the coal is stored in storage baskets. Since the storage baskets occupy a large area when laid flat, a load-bearing frame is required to store multiple storage baskets in a centralized manner.

[0003] Although there are many kinds of load-bearing frames at present, there are still some problems. For example, most of the current load-bearing frames are assembled structures, that is, a load-bearing frame mother body is composed of a plurality of load-bearing frame sub-bodies. In the process of assembly, most of them are connected and locked by screws. When locking, the screws need to pass through the through holes set between the two adjacent frames first. There is generally a certain gap between the through hole and the screw, and they cannot fit tightly. Therefore, after the assembly is completed, due to the existence of the gap between the screw and the through hole, when the frame is subjected to a large external force, the screw may be offset, which will cause the frame to be partially dislocated, and then the overall bearing capacity of the frame is greatly reduced, posing a huge safety hazard. Utility Model Content

The abutment plate is fixed to one end of the guide rod located outside the docking rod, and the abutment plate abuts against the inner wall of the through hole on the load-bearing frame sub-body.

[0010] Preferably, a slide groove is provided through the linkage seat, and the slide groove is an arc-shaped structure.

It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0025] The present invention provides a coal mine electromechanical transport load frame, such as Figure 1-5 As shown, it comprises: a load-bearing frame sub-body 1, a connecting and locking mechanism 2 and an abutting and filling mechanism 3;

[0026] A through hole is provided on the load frame sub-body 1, and the connecting and locking mechanism 2 is docked in the through hole of the load frame sub-body 1, and two adjacent load frame sub-bodies 1 are assembled and combined through the connecting and locking mechanism 2 to form an integral structure;

[0027] The connection and locking mechanism 2 includes a docking rod 21, a chuck 22, a locking screw 23, and a nut 24. The docking rod 21 is connected to the through-holes of two adjacent load frame sub-bodies 1. The chuck 22 is fixed to one end of the docking rod 21 and abuts against one of the load frame sub-bodies 1. The locking screw 23 is slidably connected to the axis of the docking rod 21. The nut 24 is screwed onto the locking screw 23 and abuts against the other load frame sub-body 1.

[0028] A cylindrical mounting cavity is provided inside the docking rod 21. The abutment filling mechanism 3 includes an abutment plate 31 and a guide rod 32. The guide rod 32 is radially slidably connected to the docking rod 21 and is partially located in the mounting cavity of the docking rod 21. The abutment plate 31 is fixed to one end of the guide rod 32 located outside the docking rod 21 and abuts against the inner wall of the through hole in the load-carrying frame sub-body 1.

[0029] The abutting filling mechanism 3 further includes a docking plate 33 and a linkage seat 34. The docking plate 33 is fixed to the other end of the guide rod 32 and is located in the internal cavity of the docking rod 21. The linkage seat 34 is fixed to the side of the docking plate 33 away from the guide rod 32.

[0030] A slide groove 35 is provided through the linkage seat 34, and the slide groove 35 has an arc-shaped structure. A protrusion 36 is fixed on the side wall of the locking screw 23, located inside the installation cavity of the docking rod 21, and a linkage rod 37 is provided on the protrusion 36, which slides and is engaged in the slide groove 35.

[0031] It should be noted that, due to the existence of gaps between the screws and the through holes during the assembly of the existing load-bearing frame, when the frame is subjected to a large external force, the screws may be offset, which may cause partial dislocation of the frame, thereby greatly reducing the overall load-bearing capacity of the frame, and posing a great safety hazard. In order to solve this problem, a connecting locking mechanism 2 and an abutting filling mechanism 3 are provided in the present solution. The two adjacent load-bearing frame sub-bodies 1 are limited by the docking rod 21 in the connecting locking mechanism 2, and at the same time, the nut 24 is screwed and docked with the locking screw 23, thereby forming a locking structure to quickly connect and lock the two adjacent load-bearing frame sub-bodies 1 to form an integral structure, and when locked, the locking screw 23 The internal thread of the nut 24 is linked and slides in the docking rod 21, and drives the linkage rod 37 in the abutment filling mechanism 3 to move synchronously, so that the linkage rod 37 slides in the slide groove 35, and at the same time, the docking plate 33 is pushed to move through the limiting effect of the slide groove 35, and then the abutment plate 31 is driven to move through the guide rod 32, so that the abutment plate 31 abuts on the inner wall of the through hole of the load-bearing frame sub-body 1, thereby achieving the filling effect of the gap between the docking rod 21 and the inner wall of the through hole, and effectively avoiding the existence of the gap. When the frame is subjected to a large external force, the two adjacent load-bearing frame sub-bodies 1 may be offset, which will cause the problem of local misalignment of the frame, thereby effectively improving the overall stability and structural strength of the load-bearing frame.

[0032] Specifically, in this embodiment, the present scheme mainly includes a load-bearing frame sub-body 1, a connecting locking mechanism 2, an abutting filling mechanism 3, a limit plate 4, a reset spring 5 and a pull ring 6. When in use, the locking screw 23 is pulled by the pull ring 6 to make the abutting plate 31 fit with the outer wall of the docking rod 21, and then the docking rod 21 is docked as a whole in the through hole between the two adjacent load-bearing frame sub-bodies 1. At this time, the pull ring 6 is released, and under the elastic force of the reset spring 5, the locking screw 23 slides and drives the abutting plate 31 to fit with the through hole. The inner wall abuts, and then the nut 24 is screwed onto the locking screw 23 until the nut 24 abuts and is locked with the load-bearing frame sub-body 1, and in the process of screwing, the locking screw 23 is linked with the inner thread of the nut 24 and slides in the docking rod 21. At this time, the linkage rod 37 slides synchronously in the slide groove 35, and the docking plate 33 is pushed to move by the limiting effect of the slide groove 35, and then the abutment plate 31 is driven to move by the guide rod 32, so that the abutment plate 31 is firmly abutted against the inner wall of the through hole of the load-bearing frame sub-body 1.

The plurality of abutment plates 31 are provided at equal angles and are combined together to form a cylindrical structure.

[0034] In this embodiment, the provision of a plurality of abutment plates 31 effectively improves the firmness and stability of the connection and locking between two adjacent load-carrying frame sub-bodies 1 .

[0035] In a further preferred embodiment of the present invention, Figure 1-5 As shown, a limit plate 4 is fixed on the locking screw 23, and a return spring 5 is sleeved on the outside of the locking screw 23. One end of the return spring 5 abuts against the limit plate 4, and the other end abuts against the bottom end of the installation cavity of the docking rod 21.

[0036] In this embodiment, the locking screw 23 can be quickly reset by the reset spring 5 and drive the abutment plate 31 to move in conjunction.

[0037] In a further preferred embodiment of the present invention, Figure 1-5 As shown, the length of the locking screw 23 is greater than the docking rod 21 , and a pull ring 6 is fixed to the end of the locking screw 23 away from the nut 24 .
