Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of ground rolling repair welding, and specifically relates to a ground rolling repair welding repair auxiliary bracket for mining. Background Art
[0002] The underground lifting and transportation operations in mines usually use winches or winches. During the operation, in order to prevent the wire ropes of the winches and winches from dragging on the ground and to ensure a certain tension, it is necessary to use multiple ground rollers on the transportation path to support and drive the wire ropes. Currently, the commonly used mining ground rollers are mostly made of cast iron, and are composed of a frame, a drum, an end cover, a bearing and a center shaft. The drum is fixed with end covers at both ends, the bearings are located in the end covers, and the center shaft is inserted in the bearings. The two ends of the center shaft are supported and fixed by the frame. When working, the rotation of the drum and the end cover is achieved through the cooperation of the center shaft and the bearing, thereby supporting the transmission of the wire rope.
[0003] In the long-term operation of the ground roller, due to the large force on the ground roller during transportation, the friction between the wire rope and the ground roller drum is large, which causes serious wear on the outer surface of the middle position of the ground roller drum. In traditional mine transportation production operations, ground rollers with severe drum wear are usually directly scrapped and replaced, resulting in serious waste of resources; in order to extend the service life of the ground roller and reduce the procurement cost of the ground roller, at present, for ground rollers where only the drum is worn and the other parts can be used normally, the worn parts of the drum are repaired by surfacing welding to repair the drum.
[0004] However, at present, the repair welding of the ground roller is usually carried out directly on the ground. Due to the lack of restriction on the rolling path of the ground roller, there is a problem that the ground roller is easy to deviate and is not convenient for welding during the repair welding process. In addition, due to the limited height of the end cover, the welding slag or other debris on the ground dropped during the repair welding process will adhere to the roller, affecting the normal progress of the repair welding operation, requiring frequent cleaning of the ground, and low repair welding efficiency.

[0026] At present, the repair welding of the floor roller 100 is usually carried out directly on the ground. Therefore, there is a problem that the floor roller 100 is easy to deviate during the repair welding of the floor roller 100, which is not convenient for welding. In addition, welding slag or other debris on the ground dropped during the repair welding process may adhere to the roller 101, affecting the normal progress of the repair welding operation, requiring frequent cleaning of the ground, and low repair welding efficiency.
[0027] In view of the above problems, the present application makes improvements and innovations and proposes the following embodiments.
[0028] In some embodiments, see Figure 1-Figure 4The present application provides a mine ground rolling repair welding auxiliary bracket, including a support frame 1, a bottom plate 2, a fixing block 3, a guide rod 4, a first guide plate 5, a second guide plate 6, and a positive and negative double-headed stud 7. The bottom plate 2 is horizontally fixedly installed on the support frame 1, and an avoidance groove 201 is opened at the middle position of the bottom plate 2. Two guide rods 4 are symmetrically installed at the left and right ends of the bottom plate 2 through the fixing block 3. The two ends of the two guide rods 4 are symmetrically arranged at the positions of the front and rear sides of the bottom plate 2. The first guide plate 5 and the second guide plate 6 are parallel to each other. When working, please refer to Figure 2 , Figure 3 , Figure 4 The roller 101 of the floor roller 100 to be repaired is horizontally placed on the top of the first guide plate 5 and the second guide plate 6, and the inner sides of the two end covers 102 of the floor roller 100 to be repaired are just in contact with the outer sides of the first guide plate 5 and the second guide plate 6 respectively.
[0029] In this way, the two ends of the roller 101 of the floor roller 100 to be repaired are supported by the symmetrically arranged first guide plate 5 and the second guide plate 6, and the first guide plate 5 and the second guide plate 6 limit the two end covers 102 of the floor roller 100. In the process of welding and repairing the rolling floor roller 100, the first guide plate 5 and the second guide plate 6 can limit and guide the rolling floor roller 100, so that the floor roller 100 can roll on the first guide plate 5 and the second guide plate 6 in a horizontal direction perpendicular to the axial direction of the floor roller 100. The ground roller 100 is prevented from deviating during the rolling process, so that it is convenient for the staff to perform surfacing welding repair on the roller 101 of the ground roller 100; in the specific operation, one person can roll the ground roller 100 and perform welding, or one person can be responsible for slowly rolling the ground roller 100 and the other person can be responsible for welding. However, since the first guide plate 5 and the second guide plate 6 can form a limiting and guiding effect on the ground roller 100, the ground roller 100 is prevented from deviating during the rolling process, and the quality of the repair welding of the ground roller 100 can be effectively guaranteed, and the efficiency of the repair welding can be improved.
[0030] In addition, in the present embodiment, the support frame 1 and the bottom plate 2 are provided to place the floor roller 100 to be repaired at a certain height from the ground, and the avoidance groove 201 is opened at the middle position of the bottom plate 2, so that the welding slag dropped during the repair welding process can fall on the bottom plate 2 or the ground to stay away from the floor roller 100, and the small amount of welding slag dropped on the bottom plate 2 can be cleaned to the ground through the avoidance groove 201, so that the repair welding environment of the floor roller 100 can be kept clean, and the welding slag or other debris during the repair welding process can be avoided from adhering to the drum 101 of the floor roller 100 to interfere with the repair welding operation. There is no need to frequently clean the ground, which is convenient for ensuring the normal progress of the repair welding operation, and can effectively ensure the repair welding quality and improve the repair welding efficiency.
[0031] In the utility model, the first guide plate 5 and the second guide plate 6 can slide forward and backward along the axial direction of the guide rod 4, a double-ended stud 7 with positive and negative threads is horizontally installed between the first guide plate 5 and the second guide plate 6, a hexagonal nut 701 is arranged at the middle position of the double-ended stud 7, the first guide plate 5 and the second guide plate 6 are symmetrically installed on the threaded sections at both ends of the double-ended stud 7, and the length direction of the double-ended stud 7 with positive and negative threads is parallel to the axial direction of the two guide rods 4.
[0032] In this way, by limiting the first guide plate 5 and the second guide plate 6 through the two guide rods 4 and rotating the positive and negative thread stud 7 through the hexagonal nut 701, the horizontal spacing between the first guide plate 5 and the second guide plate 6 can be adjusted, so that the ground roller 100 of different specifications and lengths can be supported and placed by the auxiliary bracket for welding and repairing the ground roller for mining. It has good adaptability to the length of the ground roller 100 and can meet the needs of welding and repairing ground rollers 100 of various specifications and lengths. There is no need to produce matching auxiliary brackets for each length of the ground roller 100, saving manufacturing costs. In this embodiment, an avoidance groove 201 is opened at the middle position of the bottom plate 2 to facilitate the use of a wrench to rotate the hexagonal nut 701 on the positive and negative thread stud 7, thereby providing operating space for the staff, and the operation is convenient and easy to use.
[0033] In some embodiments, see Figure 3 The horizontal height of the upper end surface of the first guide plate 5 and the second guide plate 6 is higher than the horizontal height of the fixing block 3, the guide rod 4, and the positive and negative thread studs 7, so as to ensure that the lower surface of the roller 101 of the floor roller 100 is always at a certain distance from the bottom plate 2, the fixing block 3, the guide rod 4, the positive and negative thread studs 7 and other components during the repair welding process, thereby effectively avoiding welding slag or other debris from adhering to the roller 101 of the floor roller 100 during the repair welding process, facilitating the normal progress of the repair welding operation, and effectively ensuring the repair welding quality and improving the repair welding efficiency.
[0034] In some embodiments, see Figure 3 The installation height of the guide rod 4 and the positive and negative thread studs 7 is lower than the height of the lowest point of the end cover 102 of the ground roller 100, so as to avoid the interference of the guide rod 4 and the positive and negative thread studs 7 on the rolling of the ground roller 100 during the repair welding process, which can effectively ensure the normal progress of the repair welding operation to ensure the quality of the repair welding.
[0035] In some embodiments, see Figure 1-Figure 4, the fixing block 3 is detachably provided with a locking bolt 8 which vertically penetrates the guide rod 4, the fixing block 3 and the bottom plate 2, so that the two guide rods 4 can be installed by the locking bolt 8; specifically, when assembling the auxiliary bracket for ground rolling welding repair of the mine or replacing the positive and negative thread stud 7, the first guide plate 5 and the second guide plate 6 are first symmetrically installed on the threaded sections at both ends of the positive and negative thread stud 7, and then the two guide rods 4 are passed through the first guide plate 5, the second guide plate 6 and the fixing block 3, and then the two guide rods 4 are fixed to the fixing block 3 by the locking bolt 8. On the one hand, it is convenient for the assembly of the auxiliary bracket and the replacement of the positive and negative thread stud 7, and on the other hand, it can ensure the stability of the guide rod 4 in the process of adjusting the spacing between the first guide plate 5 and the second guide plate 6.
[0036] In specific applications, the locking bolt 8 can also be installed by horizontally penetrating the guide rod 4 and the fixing block 3 at the same time, or by other methods that facilitate the disassembly and assembly of the guide rod 4.
[0037] In some embodiments, see Figure 1-Figure 4 Limit blocks 9 are fixedly installed on the left and right ends of the first guide plate 5 and the second guide plate 6, so that the position of the ground roller 100 on the first guide plate 5 and the second guide plate 6 can be limited by the limit blocks 9, so as to prevent the ground roller 100 from falling off the first guide plate 5 and the second guide plate 6 during the rolling welding repair process, or destroying the balance of the auxiliary bracket and causing safety accidents.
[0038] Finally, it should be noted that although the embodiments of the utility model have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the utility model. Ordinary technicians in the field can make changes, modifications, substitutions and variations to the above embodiments within the scope of the utility model, which should all be included in the scope of protection of this application.
