Description

Technical Field

[0001] The utility model belongs to the technical field of the installation of hydraulic pipelines of coal mine hydraulic supports, and particularly relates to a standardized and easily replaceable pipe row assembly structure for hydraulic supports. Background Art

[0002] As the roof support of the coal mining face, hydraulic supports are widely equipped in coal mining and excavation in China. Since the original hydraulic supports need to perform actions such as support, moving the support, and pulling in the underground, a large number of working cylinders are installed on the hydraulic supports, and the transportation of emulsion to each working cylinder is realized through hydraulic hoses. However, the inner wall of the hydraulic hose is rough and pitted, with a large flow resistance, which will cause a large kinetic energy loss. In addition, the hoses are often stacked and fixed in welded pipe clamps on the hydraulic supports. When the hydraulic supports move, serious friction will occur between the hydraulic hoses, between the hoses and the structural members, and between the hoses and the pipe clamps, resulting in a sharp reduction in the service life of the hydraulic hoses. Coupled with the current policy support, a large number of high-performance and high-end hydraulic supports are iteratively equipped. In these hydraulic supports, stainless steel hard pipes are used to replace the hydraulic hoses for connection on the surface of large structural members. The inner wall of the stainless steel hard pipe is smooth, with a small flow resistance and small kinetic energy loss. In addition, the corrosion resistance of the stainless steel material is extremely high.

[0003] At present, the stainless steel hard pipes in the industry are fixed by two-piece pipe clamps processed by an integrated machine. The lower pipe clamp body is directly welded and fixed on the surface of the structural member. However, the parts processed by this integrated machine are all non-standard parts, which cannot realize product standardization and affect many aspects such as stocking, inventory management, and production assembly. Moreover, in this structure, the lower pipe clamp body is directly welded on the surface of the structural member, without adjustability, and has very high requirements for assembly accuracy and operation accuracy, which affects work efficiency. In addition, the upper pipe clamp body of this structure acts as a cover plate, and a single cover plate is shared by multiple pipes. Once the pipe row needs to be replaced underground, the entire set of stainless steel hard pipes needs to be removed, seriously affecting disassembly, installation, and maintenance. Summary of the Utility Model

[0004] In order to solve the above technical problems existing in the prior art, the utility model provides a standardized and easily replaceable pipe row assembly structure for hydraulic supports, which has a simple structure, is easy to assemble and disassemble, is safe and reliable, and is convenient for maintenance.

[0005] In order to solve the above technical problems, the utility model adopts the following technical scheme: A standardized and easily replaceable pipe row assembly structure for hydraulic supports, including a strip-shaped through-groove base arranged horizontally in the left-right direction. A plurality of T-shaped nuts are arranged in the strip-shaped through-groove base along the length direction. A plurality of pipe clamp assemblies are arranged on the top of the strip-shaped through-groove base along the length direction. Each pipe clamp assembly is sequentially provided with a plurality of groups of single-hole clamping assemblies along the height direction. All groups of single-hole clamping assemblies of the same pipe clamp assembly are connected in series by two vertically penetrating long screws. The lower end of each long screw is threadedly connected to a T-shaped nut.

[0006] The strip-shaped through-groove base includes a rectangular chute that is open from left to right inside, and a long hole that is equal in length to the rectangular chute and communicates with it is provided at the top of the strip-shaped through-groove base. The width of the rectangular chute is greater than the width of the long hole.

[0007] The T-shaped nut includes a disk seat and an internal thread sleeve integrally provided on the top of the disk seat. The outer diameter of the internal thread sleeve is smaller than the outer diameter of the disk seat. A rectangular plane is milled on the lower part of the outer circle of the internal thread sleeve. The lower side of the rectangular plane is in contact with the top surface of the disk seat. The distance from the center of the rectangular plane along the radial direction of the internal thread sleeve to the outer circle of the internal thread sleeve is equal to the width of the long hole. The height of the rectangular plane is greater than or equal to the height of the long hole. The disk seat is located inside the rectangular chute, and the rectangular plane of the internal thread sleeve fits against the front side or the rear side of the long hole.

[0008] Each group of single-hole clamping components includes an upper cover plate and a lower support plate that are identical in structure and symmetrically arranged up and down. In the middle of the bottom surface of the upper cover plate, there is an upper semi-circular hole that is open at the bottom and open from front to back. In the middle of the top surface of the lower support plate, there is a lower semi-circular hole that is open at the top and open from front to back. The upper semi-circular hole and the lower semi-circular hole correspond up and down to form a pipe-clamping hole. On the left and right sides of the upper semi-circular hole of the upper cover plate, there is a through-up-and-down upper T-shaped hole respectively. The thicker section of the upper T-shaped hole is above the thinner section. On the left and right sides of the lower semi-circular hole of the lower support plate, there is a through-up-and-down lower T-shaped hole respectively. The thicker section of the lower T-shaped hole is below the thinner section. The upper T-shaped holes and the lower T-shaped holes on the left and right sides are all corresponding and penetrating up and down; a long screw passes through all the upper T-shaped holes and the lower T-shaped holes and is threadedly connected to the internal thread sleeve at the lower end. The upper part of the internal thread sleeve extends into the thicker section of the lower T-shaped hole of the lowermost lower support plate.

[0009] A backing plate that sleeves on two long screws is provided on the top surface of the upper cover plate of the uppermost group of single-hole clamping components.

[0010] With the above technical solution, the specific use process of the present utility model is as follows: First, weld and fix the strip-shaped through-groove base on the outer surface of the hydraulic support structure member. Then, slide several T-shaped nuts into one end port inside the strip-shaped through-groove base. The disc seat of the T-shaped nut slides in the rectangular chute, and the rectangular plane of the inner-thread sleeve slides along the front or rear side of the long hole. Then, put the thicker section of the lower T-shaped hole of the lower support plate onto the upper section of the inner-thread sleeve protruding from the strip-shaped through-groove base. Then, place a stainless steel hard pipe into the lower semi-circular hole of the lower support plate. Next, install a cover plate on the lower support plate. The upper semi-circular hole of the upper cover plate is sleeved onto the upper semi-circle of the stainless steel hard pipe. Then, continue to install multiple groups of single-hole clamping components on it according to the actual situation, and insert each stainless steel hard pipe into the pipe-clamping hole of each group of single-hole clamping components correspondingly. Then, place a backing plate on the top surface of the upper cover plate at the topmost layer. Then, pass a long screw through the backing plate and several groups of single-hole clamping components. The lower end of the long screw penetrates into the inside of the T-shaped nut and is slightly screwed into the T-shaped nut. Move the entire pipe clamp assembly and the T-shaped nut left and right on the strip-shaped through-groove base, and finally tighten the long screw to achieve the assembly and fixation of the pipe row. Install and fix other pipe clamp components to the strip-shaped through-groove base according to the above operation process.

[0011] In the present utility model, an upper T-shaped hole is opened on the upper cover plate, and a lower T-shaped hole is provided on the lower support plate. That is to say, the structures of the upper cover plate and the lower support plate are the same, and the upper cover plate and the lower support plate can be used interchangeably. Especially when the lower support plate at the lowermost layer is assembled with the T-shaped nut, it is convenient for workers to operate on site. Therefore, the upper cover plate and the lower support plate can be produced as standard parts.

[0012] A rectangular plane is milled on the lower part of the outer circle of the inner-thread sleeve of the T-shaped nut to fit with the rectangular plane of the inner-thread sleeve and the front or rear side of the long hole. When rotating the long screw, it can ensure that the T-shaped nut does not rotate, ensuring the reliability of the installation connection.

[0013] In summary, the assembly structure form of the present utility model is reasonably developed. The structures of the strip-shaped through-groove base and the T-shaped nut enable the stainless steel hard pipe row to have adjustability, reducing the installation difficulty. At the same time, the split design of the single-hole clamping component realizes standardized production, can be stocked in large quantities, and has a single model, which is convenient for inventory management. In addition, the split single-hole clamping component is also more convenient for maintenance, disassembly and assembly underground, and there is no need to disassemble the entire pipe row, improving the work efficiency and construction safety.
