Technical Field
[0001] The utility model relates to the field of electromechanical technology, in particular to an adjusting device for a slag retaining support. Background Art
[0002] The coal mine working face uses ZRL39600 / 25 / 40D rock retaining supports along the goaf. This set of rock retaining supports is arranged in the form of two frames, each consisting of three sections, with the functions of supporting the goaf, self-moving frames, and isolating the working space from the goaf. The rock retaining supports along the goaf are arranged behind the end supports, with one side close to the goaf and the other side close to the roadway. The two frames serve as anchor points for each other to achieve alternating self-movement of the supports.
[0003] During the operation, the roof of the goaf was broken and fell, resulting in the roof on the goaf side being higher than the roof on the roadway side. The actual maximum misalignment between the two slag retaining supports was 250mm, which often caused the tensioning jacks to be crushed during the lowering of the slag retaining supports, affecting the adjustment and support of the slag retaining supports, and further causing the deterioration of the roof of the goaf-retained roadway. Therefore, a slag retaining support adjustment device was proposed to address the above problems. Utility Model Content

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.
[0019] Specific examples are given below.
[0020] See also Figures 1 to 4 , a gangue retaining support adjustment device includes a connecting rod mechanism 1, the connecting rod mechanism 1 is arranged between the first ear seat 2 and the second ear seat 8, one end of the first ear seat 2 is plugged into and installed with a first rotating shaft 3, one end of the second ear seat 8 is centrally provided with a jack body 7, and a third rotating shaft 9 is plugged into and installed between the second ear seat 8 and the top of the jack body 7, one end of the bottom of the jack body 7 is installed with a connecting piston 6, and the bottom end of the connecting piston 6 is fixedly installed with a follower base 4 in the center, and the second rotating shaft 5 is plugged into and installed in the center of the end face of the follower base 4; the connecting rod mechanism 1 includes a rotating support 11 and an assembly ear plate 14, the rotating support 11 is arranged between the first ear seats 2, and the first rotating shaft 3 is plugged into and installed in the center of the end face of the rotating support 11, one end of the rotating support 11 is fixedly installed with an assembly ear plate 14 by welding, and one end of the assembly ear plate 14 is sleeved and installed on the outer side of the follower base 4, and both ends of the second rotating shaft 5 pass through the assembly ear plate 14;
[0021] The connecting rod mechanism 1 is used to conveniently connect and install the jack body 7 between the first ear seat 2 and the second ear seat 8. The rotating support 11 can be rotatably installed between the first ear seat 2 through the first rotating shaft 3. The assembly ear plate 14 can be rotatably installed on the outside of the follower base 4 through the second rotating shaft 5. The top end of the jack body 7 can be rotatably installed between the second ear seat 8 through the third rotating shaft 9. As the jack body 7 works, the position of the connecting piston 6 and the follower base 4 can be adjusted. At the top of the jack body 7, the angle with the second ear seat 8 is adjusted through the third rotating shaft 9. At the bottom of the jack body 7, the angle of the follower base 4, the connecting rod mechanism 1 and the first ear seat 2 are adjusted through the second rotating shaft 5 and the first rotating shaft 3, thereby changing the stroke.
[0022] The rotating support 11 has the same structural shape as the follower base 4, and the assembly ear plate 14 has the same structural shape as the first ear seat 2; this makes it easy to install the rotating support 11 between the first ear seats 2 and the assembly ear plate 14 on the outside of the follower base 4, thereby improving the ease of splicing and assembly and making it more convenient to use.
[0023] Both ends of the rotating support 11 are fitted with wear-resistant pads 12, and the center of one end surface of the rotating support 11 is fitted with a buffer pad 13; the provision of the wear-resistant pad 12 can improve the protection effect of the surface of the rotating support 11 and reduce wear; the provision of the buffer pad 13 can reduce the impact effect generated by the rotating support 11 when it collides;

When the second rotating shaft 5 rotates inside the transmission sleeve 15, the transmission sleeve 15 can protect the assembly ear plate 14.
[0025] During the operation of the slag retaining support, due to the different pressures on the left and right sides of the slag retaining support, the slag retaining support will have a lateral displacement to the side with smaller pressure, and deviate from the set travel route, or because the top of the slag retaining support on the goaf side is broken, the top coal is broken and falls during the process of lowering and pulling the support, resulting in an increase in the height of the tunnel; after the goaf side support is tightened, there is a height difference with the tunnel side support; when the height difference is greater than 200mm, the slag retaining support on the tunnel side will be unable to lower or pull the support or the pulling jack will be crushed. By setting a pulling jack connecting rod device, as the jack body 7 During operation, the position of the connecting piston 6 and the follower base 4 can be adjusted. At the top of the jack body 7, the angle with the second ear seat 8 is adjusted through the third rotating shaft 9. At the bottom of the jack body 7, the angle between the follower base 4 and the assembly ear plate 14 is adjusted through the second rotating shaft 5, and the rotating support 11 is adjusted to the angle with the first ear seat 2 through the first rotating shaft 3, thereby increasing the staggered height of the rock retaining bracket by about 250mm, and increasing the height difference of the rock retaining bracket from the original 250mm to 500mm, ensuring that the brackets serve as fulcrums for each other to achieve self-movement.
