Description

Technical Field

[0001] The utility model relates to the technical field of coal mine comprehensive mining, in particular to a flexible track used on a vertical cylinder of an underground hydraulic support. Background Art

[0002] The fully mechanized mining face in underground coal mines is the main place for coal mining. It has the characteristics of a large number of mining and transportation equipment, large volume, narrow space, constant deformation, high coal dust environment, and harsh working conditions. The fully mechanized mining face is also a frequent site for coal mine accidents. Accidents such as water seepage and gas explosions occur at fully mechanized mining faces at a much higher rate than at other places. Real-time inspection of the equipment environment of fully mechanized mining faces is an important means to ensure the normal operation of equipment and prevent major safety accidents. The use of inspection robots that walk along the tracks installed on the fully mechanized mining face to perform inspections is currently a key technology to replace manual work to complete high-intensity and high-risk inspection tasks and realize automated inspections of working faces.

[0003] The track on which the inspection robot walks is usually installed on the scraper conveyor, hydraulic support and other working equipment in the comprehensive mining working face. The structural forms of the track mainly include wire rope track, rigid track and flexible track. The flexible track includes a rigid track and a flexible connection mechanism connected between the rigid tracks, which is usually used in the installation environment where the track needs to be deformed. The inspection robot has poor stability when walking along the wire rope track and is prone to shaking when walking. The rigid track and the flexible track have better stability than the wire rope track. The inspection robot is more stable and reliable when walking along the rigid track and the flexible track. Due to frequent shifting and lifting of the frame, the hydraulic support has a deformation requirement for the track installed on it. Generally, a wire rope track or a flexible track is installed on the hydraulic support. For the flexible track installed on the underground hydraulic support, it is usually suspended on the underground hydraulic support by a chain. The connection between the track and the hydraulic support formed by the chain is a flexible connection. Therefore, when the inspection robot walks along the flexible track, the flexible track itself is prone to shaking relative to the hydraulic support, thereby affecting the stability of the inspection robot.

[0028] In order to more clearly demonstrate the purpose, technical solutions and advantages of the present invention, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0029] Example

[0030] like Figure 1 , 2As shown, the present embodiment is a flexible rail for underground hydraulic support cylinders, including an I-shaped rigid rail 1 and a flexible connection mechanism 2 connected between the I-shaped rigid rails 1. The I-shaped rigid rail 1 is a conventional I-shaped rail, which includes a vertical plate 11 and a lower horizontal plate 12 and an upper horizontal plate 13 fixedly mounted at both ends of the vertical plate 11 and parallel to the vertical plate 11. The I-shaped rigid rail 1 is detachably fixedly connected to the hydraulic support cylinder 600 through the hydraulic support connection mechanism 3. The hydraulic support is a device used to control the mine pressure of the coal mining working face on the underground comprehensive mining working face of a coal mine, and the hydraulic support cylinder is a mechanism in the hydraulic support used to adjust the support height and bear the load. Figure 2-4 As shown, the hydraulic support connection mechanism 3 includes a rail connection bracket 31 which is detachably fixedly connected to the vertical plate 11 of the I-shaped rigid rail 1 and a cylinder clamping sleeve which is detachably fixedly connected to the hydraulic support cylinder 600. The rail connection bracket 31 is fixedly connected to a cylinder clamping sleeve connecting plate 33 which is detachably fixedly connected to the cylinder clamping sleeve. A reinforcing rib plate 34 is fixedly connected between the rail connection bracket 31 and the cylinder clamping sleeve connecting plate 33. The cylinder clamping sleeve includes two detachable, matched, and fixedly connected cylinder clamping half sleeves 321. After the two cylinder clamping half sleeves 321 are docked, the hydraulic support cylinder 600 can be clamped and fixed between the two cylinder clamping half sleeves 321.

[0031] In the flexible track for underground hydraulic support cylinders of the present embodiment, the I-shaped rigid track 1 constituting the flexible track is detachably fixedly connected to the hydraulic support cylinder 600 through the hydraulic support connection mechanism 3, and the hydraulic support connection mechanism 3 comprises a track connection bracket 31 and a cylinder clamping sleeve fixedly connected to the track connection bracket 31 through the cylinder clamping sleeve connection plate 33, wherein the track connection bracket 31 is detachably fixedly connected to the vertical plate 11 of the I-shaped rigid track 1, and the cylinder clamping sleeve is detachably fixedly connected to the hydraulic support cylinder 600, thereby forming a rigid connection between the flexible track and the hydraulic support cylinder 600. Compared with the flexible track that is suspended on the hydraulic support by a chain and forms a flexible connection with the hydraulic support, the flexible track for underground hydraulic support cylinders of the present embodiment, which forms a rigid connection with the hydraulic support cylinder 600, is not easy to shake relative to the hydraulic support when the inspection robot walks along the track, and the inspection robot runs more stably and reliably when walking along the flexible track of the present embodiment.

[0032] In order to enhance the stability of the connection between the I-shaped rigid rail 1 and the hydraulic support cylinder 600, further, the rail connecting bracket 31, the cylinder clamping half sleeve 321, the cylinder clamping sleeve connecting plate 33, and the reinforcing rib plate 34 constituting the hydraulic support connection mechanism 3 are all rigid parts.

[0033] Further, such as Figure 1 , 4As shown, each cylinder clamping half sleeve 321 includes a semicircular section with a semicircular cross section, and the curvature of the semicircle matches the curvature of the cross section of the hydraulic support cylinder 600. After the two cylinder clamping half sleeves 321 are butted, the hydraulic support cylinder 600 is clamped and fixed between the semicircular sections of the cylinder clamping half sleeves 321. Furthermore, the two cylinder clamping half sleeves 321 are detachably fixedly connected by bolts passing through the ear plates thereof.

[0034] In order to enhance the clamping and fixing effect of the cylinder clamping half sleeve 321 on the hydraulic support cylinder 600, further, as Figure 1 , 4 As shown, each of the vertical cylinder clamping half sleeves 321 includes a vertical cylinder clamping half sleeve side plate 3211 and a vertical cylinder clamping half sleeve top plate 3212 which are vertically fixedly connected, the vertical cylinder clamping half sleeve side plate 3211 can contact the curved surface of the hydraulic support vertical cylinder 600, and the vertical cylinder clamping half sleeve top plate 3212 can contact the flat surface of the hydraulic support vertical cylinder 600. Further, the semicircular section of the vertical cylinder clamping half sleeve 321 is formed on the vertical cylinder clamping half sleeve side plate 3211.

[0035] like Figure 1 , 4 As shown, in order to make the connection more secure, further, the track connection bracket 31 is detachably fixedly connected to the vertical cylinder clamping half set top plate 3212. As for the specific structure of the hydraulic support connection mechanism 3, further, as Figure 2-4 As shown, the track connection bracket 31 is perpendicular to the vertical cylinder clamping sleeve connection plate 33. Further, the vertical cylinder clamping sleeve connection plate 33 is detachably fixedly connected to one of the two vertical cylinder clamping half sleeves 321.

[0036] Regarding the specific structure of the flexible connection mechanism 2, further, as Figure 5-7 As shown, the flexible connection mechanism 2 includes a cover plate 21 fixedly connected to the I-shaped rigid track 1, a telescopic shield 22 connected between the two cover plates 21, and a telescopic rod 23 installed in the telescopic shield 22, one end of the telescopic shield 22 is fixedly connected to one cover plate 21, and the other end is fixedly connected to the other cover plate 21, one end of the telescopic rod 23 is connected to one cover plate 21 through a universal joint 24, and the other end is connected to the other cover plate 21 through a universal joint 24. In this embodiment, the telescopic rod 23 can adopt a conventional telescopic rod structure, which is composed of a plurality of rods that are sleeved and slidably connected. The flexible connection mechanism 2 of this embodiment can achieve bending deformation and telescopic deformation by setting the telescopic shield 22, the telescopic rod 23, and the universal joint 24. When the hydraulic support for installing the flexible track is moved or lifted, the entire flexible track can be bent and telescopically deformed through the flexible connection mechanism 2 along with the moving and lifting of the hydraulic support.

[0037] In order to enhance the adaptability of the flexible track to the walking of the inspection robot, further, such as Figure 5 , 6 As shown, the telescopic shield 22 is formed with a telescopic shield lower horizontal portion 221, a telescopic shield vertical portion 222 connected to the telescopic shield lower horizontal portion 221, and a telescopic shield upper horizontal portion 223 connected to the telescopic shield vertical portion 222. The telescopic shield lower horizontal portion 221 is connected between the upper surfaces of the lower horizontal plate 12 of the I-shaped rigid track 1, the telescopic shield vertical portion 222 is connected between the side surfaces of the vertical plates 11 of the I-shaped rigid track 1, and the telescopic shield upper horizontal portion 223 is connected between the lower surfaces of the upper horizontal plates 13 of the I-shaped rigid track 1. Conventional inspection robots generally have driving wheels that can move along the track and load-bearing wheels that bear the weight of the inspection robot. When the inspection robot is installed on the flexible track of this embodiment, the driving wheels and load-bearing wheels of the inspection robot can move along the side surface of the vertical plate 11 of the I-shaped rigid track 1 and the vertical portion 222 of the telescopic shield of the flexible connection mechanism 2, and can also move along the upper surface of the lower cross plate 12 of the I-shaped rigid track 1 and the lower horizontal portion 221 of the telescopic shield of the flexible connection mechanism 2. In addition, they can also move along the lower surface of the upper cross plate 13 of the I-shaped rigid track 1 and the upper horizontal portion 223 of the telescopic shield of the flexible connection mechanism 2.

[0038] Furthermore, in order to enhance the deformation ability and flexibility of the flexible connection mechanism 2, as Figure 8 As shown, a total of six telescopic rods 23 are provided which are parallel to each other. Each telescopic rod 23 is connected to the cover plate 21 via a universal joint 24 installed at both ends. The axes of the two telescopic rods 23 located at the top are in the same horizontal plane, the axes of the two telescopic rods 23 located at the bottom are in the same horizontal plane, and the axes of the two telescopic rods 23 located in the middle are in the same vertical plane.

[0039] In order to enable the flexible connection mechanism 2 to better bear the weight of the inspection robot when the inspection robot passes through the flexible connection mechanism 2, further, as Figure 8 , 9 As shown, the telescopic rod 23 is sleeved with a plurality of parallel supporting partitions 25, and the supporting partition 25 is formed with a lower horizontal portion 251 of the supporting partition, a vertical portion 252 of the supporting partition connected to the lower horizontal portion 251 of the supporting partition, and an upper horizontal portion 253 of the supporting partition connected to the vertical portion 252 of the supporting partition. The lower horizontal portion 251 of the supporting partition can contact with the lower horizontal portion 221 of the telescopic shield, the vertical portion 252 of the supporting partition can contact with the vertical portion 222 of the telescopic shield, and the horizontal portion 253 of the supporting partition can contact with the upper horizontal portion 223 of the telescopic shield.

[0040] When installing the flexible track for the underground hydraulic support cylinder of this embodiment, the track connecting bracket 31 of the hydraulic support connecting mechanism 3 is connected to one of the cylinder clamping half sleeves 321 of the cylinder clamping sleeve through the cylinder clamping sleeve connecting plate 33, and then the track connecting bracket 31 is fixed to the vertical plate 11 of the I-shaped rigid track 1 of the flexible track, and then the two cylinder clamping half sleeves 321 are spliced ​​and fixed, and the hydraulic support cylinder 600 is clamped and fixed between the two spliced ​​cylinder clamping half sleeves 321, and then the flexible track for the underground hydraulic support cylinder of this embodiment is fixedly installed on the hydraulic support cylinder 600 through the hydraulic support connecting mechanism 3. When the inspection robot walks along the flexible track of this embodiment to perform inspection tasks, its driving wheels and load-bearing wheels can walk along the side surfaces of the vertical plate 11 of the I-shaped rigid track 1 and the vertical portion 222 of the telescopic shield of the flexible connection mechanism 2, and can also walk along the upper surface of the lower cross plate 12 of the I-shaped rigid track 1 and the lower horizontal portion 221 of the telescopic shield of the flexible connection mechanism 2.
