Description

Technical Field

[0001] This invention relates to the field of hydraulic support repair device technology, and in particular to a hydraulic support top beam repair press. This press is mainly used to perform molding treatment on the side plates of the hydraulic support top beam to solve the deformation problem caused by wear and aging of the side plates of the hydraulic support top beam, thereby improving the repair efficiency and quality of the hydraulic support top beam. Background Technology

[0002] Hydraulic supports are hydraulic power devices that use liquid pressure to generate supporting force and automatically move to support and manage the roof. They are indispensable supporting equipment in fully mechanized coal mining. During coal mining, hydraulic supports effectively support the roof, prevent roof collapse, and ensure the safe operation of coal mining work. Their stability and reliability directly affect the production efficiency of the coal mine and the safety of the workers.

[0003] After a certain period of use, the top beam structure of a hydraulic support will experience wear and aging. Common aging phenomena include deformation of the hydraulic support top beam side plates due to severe compression, such as bending or twisting, which affects its normal support function. At the same time, paint peeling is also a common problem. Paint peeling can make the hydraulic support top beam side plates more susceptible to rust and corrosion, further reducing its service life and structural strength.

[0004] Traditional methods for repairing the side plates of hydraulic support beams have several shortcomings. Firstly, traditional presses, due to structural limitations, are unsuitable for pressing the side plates. These presses are typically located in fixed areas, making it difficult to move and adjust their positions flexibly according to actual repair needs. For some large hydraulic support beams, on-site repair is impossible, requiring disassembly and transport to a specialized workshop for fixed-point pressing. Secondly, some methods involve manual hammering of the side plates. This method is not only labor-intensive, requiring prolonged and strenuous hammering, but also inefficient. When pressing multiple deformed or cracked areas on the side plates, workers must cooperate to move the plates and perform multiple pressing operations, which is time-consuming and labor-intensive, severely impacting repair efficiency. Furthermore, the precision of manual hammering is difficult to guarantee, potentially leading to unsatisfactory pressing results and affecting the overall repair quality. Summary of the Invention

[0005] This invention provides a hydraulic support top beam repair press, which helps to solve the problem that some existing presses are located in fixed locations, making it difficult to overcome location limitations, resulting in time-consuming and labor-intensive repairs of the hydraulic support top beam side plates.

[0006] This invention is implemented as follows:

[0007] The hydraulic support top beam maintenance press includes a frame with a hoisting structure around it. At the bottom of the frame are horizontally spaced first and second pressure units. Each first pressure unit has a first rotary drive component, the output end of which is located at the bottom of the first pressure unit and is connected to several sets of pressure rollers spaced forward and backward. The pressure rollers within the same set form a clamping gap for holding the side plate of the hydraulic support top beam. The bottom of the second pressure unit has a fixed plate, with several forming blocks spaced apart on one side of the fixed plate. The tops of each forming block are connected by a linkage plate. The T-shaped structure has a lateral movement limiting structure between the linkage plate and the bottom housing of the second pressure unit. The top of the linkage plate extends into the interior of the second pressure unit. The second pressure unit is equipped with a second rotary drive component. The rotary output end of the second rotary drive component is connected to a transmission gear. An eccentrically mounted striking block is mounted on the transmission gear. The striking block is located on one side of the linkage plate. The second rotary drive component can drive the transmission gear to rotate and use the striking block to intermittently impact the linkage plate, so that the forming block can approach the fixed plate. This allows the fixed plate and the forming block to form a double-sided pressure shaping structure for the side plate of the hydraulic support top beam.

[0008] Based on the above technical solution, the frame includes a first support and a second support assembled from metal profiles, and the main structures of the first pressure unit and the second pressure unit are respectively connected to the bottom of the first support and the second support.

[0009] Based on the above technical solution, the first bracket and the second bracket are connected by a detachable structure.

[0010] Based on the above technical solution, handrails are connected to the outer walls of the first pressure unit and the second pressure unit.

[0011] Based on the above technical solution, the forming block is a vertically arranged strip block structure, and the corner of the forming block on the side of the feeding direction of the workpiece being clamped is a rounded corner structure.

[0012] Based on the above technical solution, the distance between the forming block and the fixing block gradually decreases from the feeding end to the discharging end of the clamped workpiece.

[0013] Based on the above technical solution, a buffer structure is provided between the striking block and the transmission gear, and the buffer direction is parallel to the movement direction of the forming block.

[0014] Based on the above technical solution, the surface of the pressure roller is provided with a frosted sleeve.

[0015] Based on the above technical solution, the surface of the pressure roller is provided with an anti-slip structure.

[0016] Compared with the prior art, the present invention has at least the following advantages:

[0017] 1. The hydraulic support top beam repair press of the present invention, through the setting of a movable frame and hoisting structure, can quickly transport the equipment to the location of the hydraulic support for on-site repair, eliminating the need to disassemble the top beam and transport it to a professional workshop, thus greatly saving repair time and labor costs. Simultaneously, the first and second pressure units work together to quickly and accurately press the side plates of the hydraulic support top beam, improving repair efficiency.

[0018] 2. Traditional maintenance methods require workers to perform a large amount of manual hammering and moving operations, resulting in high labor intensity. The press of this invention uses a mechanical drive system, with a first and second rotary drive component driving the pressure roller and the striking block respectively. This automates the forming process, overcoming the limitations of existing maintenance presses that rely on hydraulic cylinders and are restricted by the work environment. It also reduces manual operation and lowers the labor intensity for workers.

[0019] 3. The press of this invention, through precise structural design, such as the gradually decreasing spacing between the forming block and the fixing block, the frosted sleeve or anti-slip structure on the surface of the pressure roller, and the buffer structure between the striking block and the transmission gear, can ensure the stability and accuracy of the forming process, thereby improving the forming quality of the hydraulic support top beam side plate. Simultaneously, the double-sided pressure forming structure can perform all-around forming treatment on the hydraulic support top beam side plate, making the shape and size of the formed hydraulic support top beam side plate more in line with requirements, thus improving the overall performance and service life of the hydraulic support.

[0020] The frame in this invention features a split design and a detachable connection structure, making installation, commissioning, and maintenance of the equipment more convenient. During transportation, the first and second supports can be disassembled and separated, reducing the space occupied by the equipment and lowering transportation costs. Simultaneously, this design facilitates equipment repair and component replacement, improving maintainability. Attached Figure Description

Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

[0034] In the description of this invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0035] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0036] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0037] Example 1: Combination Figure 1-7 As shown in the figure, this embodiment discloses a hydraulic support top beam repair press, which aims to solve the problem that some existing presses have fixed processing locations, making it difficult to overcome location limitations, resulting in time-consuming and labor-intensive repairs of the hydraulic support top beam side plates. With the hydraulic support top beam repair press of this invention, efficient on-site pressing processing of hydraulic support top beam side plates can be achieved, reducing labor intensity and improving repair efficiency and quality.

[0038] Specifically, the hydraulic support top beam repair press in this embodiment includes a frame 100, which serves as the supporting structure for the entire equipment, providing a stable installation foundation for other components. Lifting lugs 400 are provided on both the left and right sides of the frame 100, serving as lifting structures to facilitate the lifting and movement of the equipment. This allows the equipment to be quickly transported to a designated location according to actual repair needs, breaking through the limitations of fixed processing locations inherent in traditional presses. At the bottom of the frame 100, a first pressure unit 200 and a second pressure unit 300 are provided, distributed laterally at intervals. These two pressure units work together to complete the pressing process for the side plate a of the hydraulic support top beam.

[0039] Furthermore, the frame 100 includes a first support 110 and a second support 120 assembled from metal profiles. Metal profiles offer advantages such as high strength, light weight, and ease of processing and assembly, ensuring the structural stability and reliability of the frame 100. The main structures of the first pressure unit 200 and the second pressure unit 300 are respectively connected to the bottom of the first support 110 and the second support 120. This split design facilitates equipment installation, debugging, and maintenance. Simultaneously, the first support 110 and the second support 120 are connected by a detachable structure, such as using bolts or snap-fit ​​connections. In this embodiment, a combination of a connecting seat and a pin is used. This detachable connection structure makes the equipment more convenient to transport and store, reducing the space occupied and lowering transportation costs.

[0040] The main structure of the first pressure unit 200 and the second pressure unit 300 is the same, both being box-type structures. This box-type structure is composed of two parts, front and rear, connected by bolts. This structure allows for changes in the width of the box-type structure according to processing requirements, facilitating the design and spacing adjustment of the pressure application structure at the bottom of the pressure unit.

[0041] The first pressure unit 200 is equipped with a first rotary drive component 210, which is the power source for the entire first pressure unit 200. In this embodiment, a motor is used. It should be noted that... Figure 1 To clearly demonstrate the overall structure, only the motor output end is shown; the main structure of the motor is not shown. This structure is existing technology, and its specific structure and working principle will not be elaborated here. Those skilled in the art can select and implement it from existing technologies based on actual operating conditions. The rotation output end of the first rotary drive component 210 is located at the bottom of the first pressure unit 200 and is driven by several sets of pressure rollers 220 spaced apart front and rear. The pressure rollers 220 and the first rotary drive component 210 are driven by a gear set. This is existing technology, and its specific structure and working principle will not be elaborated here. Those skilled in the art can select and implement it from existing technologies based on actual operating conditions. The pressure rollers 220 in the same group form a clamping gap for holding the hydraulic support top beam side plate a. That is, two pressure rollers 220 in the same group are spaced apart front and rear, and the gap between them forms the clamping gap for the workpiece to pass through. When the first rotary drive component 210 works, it drives the pressure rollers 220 to rotate. The pressure rollers 220 apply pressure to the hydraulic support top beam side plate a through the clamping gap, achieving the initial pressing and fixing effect. In addition, the rotation of the pressure roller 220 can also drive the entire device to slide relative to the side plate a of the hydraulic support top beam. This replaces the material feeding action of controlling the hydraulic support top beam during traditional maintenance, and transforms it into the activity of the processing device. The dynamic and static objects of the two processing methods change, so the handling and movement of workpieces can be reduced, and maintenance operations can be flexibly carried out in a variety of scenarios.

[0042] Combination Figure 3 As shown, the second pressure unit 300 has a fixing plate 320 at its bottom. The fixing plate 320 serves as a reference surface for the forming process, providing stable support for the side plate a of the hydraulic support top beam. Five forming blocks 330 are spaced apart on one side of the fixing plate 320, as shown... Figure 5 As shown, the tops of each molding block 330 are connected by a linkage plate 340, which has a "T"-shaped structure. This "T"-shaped linkage plate 340 can effectively transmit power, ensuring that each molding block 330 moves synchronously. Combined with... Figure 6 As shown, a lateral movement limiting structure is provided between the linkage plate 340 and the bottom housing of the second pressure unit 300. Specifically, the bottom housing of the second pressure unit 300 has a sliding groove, and the top of the linkage plate 340 is engaged in the sliding groove. This can restrict the movement direction of the linkage plate 340, so that it can only reciprocate back and forth in the horizontal direction. Figure 3 , 5 (The middle part moves up and down) to ensure the stability and accuracy of the molding process.

[0043] Combination Figure 5 As shown, the rotation output end of the second rotary drive 310 (also a motor) is connected to a first gear 350. The first gear 350 meshes with two second gears 360, and each of the second gears 360 meshes with a third gear 370. Figure 7 The third gear 370 serves as the transmission gear, and an eccentrically mounted striking block 371 is provided on it. The striking block 371 is a circular block structure, with its outer side wall extending radially outward from the third gear 370. When the striking block 371 rotates to the far end of the third gear 370, it can strike and compress the linkage plate 340, causing the linkage plate 340 to drive the forming block 330 towards the fixed plate 320, thus completing the forming action. It should be noted that each gear is pivotally connected to the main body of the second pressure unit via its own axial central shaft.

[0044] In this embodiment, the forming block 330 is a single-sided connecting transmission structure. In other embodiments, the forming block 330 may also be provided with transmission structures on both sides of its long side, so as to improve its forming strength by using double-sided transmission.

[0045] Furthermore, in combination Figure 6 As shown, the molding block 330 is a vertically arranged strip-shaped block structure. This structure can better adapt to the shape and size of the side plate a of the hydraulic support top beam, providing a uniform pressure distribution. (Reference) Figure 5 As shown, the corner of the molding block 330 on the side opposite to the feeding direction of the clamped workpiece has a rounded corner structure. Figure 5The material feeding direction of the workpiece is from right to left (this feeding direction is controlled by the rotation direction of the pressure roller 220). The inner corner of the forming block 330 near the right side has a rounded corner structure. The rounded corner structure can reduce the friction between the forming block 330 and the hydraulic support top beam side plate a, avoid scratching or damaging the hydraulic support top beam side plate a during the forming process, and also facilitate the smooth feeding and discharging of the hydraulic support top beam side plate a.

[0046] The spacing between the forming block 330 and the fixing block gradually decreases from the feeding end to the discharging end of the clamped workpiece. This design meets the process requirements of forming. At the feeding end, the spacing is larger, which facilitates the smooth entry of the hydraulic support top beam side plate. As forming progresses, the spacing gradually decreases, applying gradually increasing pressure to the hydraulic support top beam side plate, causing it to gradually deform to achieve the required shape and size, thus improving the quality and effect of forming.

[0047] Handrails 500 are connected to the outer walls of the first pressure unit 200 and the second pressure unit 300. The handrails 500 provide support for workers when moving or operating the equipment, and facilitate pulling during adjustments to the machining position of the device and the side plate a of the hydraulic support top beam. This improves the safety and convenience of equipment use. Workers can control the direction and speed of the equipment's movement by holding the handrails 500, preventing accidents such as collisions or tipping during movement.

[0048] During the specific implementation process, the on-site personnel observe and judge the wear degree of the side plate a of the hydraulic support top beam to be repaired. During the repair, the entire hydraulic support top beam is disassembled and placed on a flat ground with the bottom surface facing up. At this time, the side plate a of the hydraulic support top beam is vertically distributed upwards. Using hoisting equipment, the hydraulic support top beam maintenance press in this embodiment is lifted above the side plate a of the hydraulic support top beam. The operator uses the handrail 500 to adjust the position and angle so that the feeding end of the clamping gap between the pressure rollers 220 is aligned with the edge of the side plate a of the hydraulic support top beam. The first rotary drive 210 and the second rotary drive 310 are started. First, the rotation of the pressure rollers 220 will press the side plate a of the hydraulic support top beam from the inside and outside. Under the influence of friction, the device moves relative to the side plate a of the hydraulic support top beam. During the movement, the pressure rollers 220 perform preliminary pressing treatment on the pressing area. As the side plate a of the hydraulic support top beam enters the gap between the fixed plate 320 and the pressing block 330, the fixed plate 320 is located on one side of the side plate a of the hydraulic support top beam and acts as a reference support structure. The pressing block 330 on the other side is subjected to the force of the third gear 370 driving the striking block 371 to rotate, intermittently performing fine pressing treatment on the side plate a of the hydraulic support top beam, and the pressing strength gradually increases.

[0049] Example 2: Based on Example 1, combined with Figure 8As shown, in this embodiment, a buffer structure is provided between the striking block 371 and the transmission gear, with the buffer direction parallel to the movement direction of the forming block 330. Specifically, the third gear 370 is provided with a sliding cavity 372, the length direction of which is parallel to the radial direction of the third gear 370. The striking block 371 and the third gear 370 are movably connected. An inverted "T"-shaped slide rod 373 is fixedly connected to the bottom of the striking block 371. The outer contour of the slide rod 373 fits the inner contour of the sliding cavity 372. The top of the sliding cavity 372 has a suitable space for the slide rod 373 to move laterally. A return spring 374 abuts against the inner wall of the sliding cavity 372. The return spring 374 can drive the striking block 371 to move radially outward relative to the third gear 370. During the intermittent impact of the striking block 371 on the linkage plate 340, the buffer structure can absorb part of the impact force, reduce the damage to the various components of the equipment, and extend the service life of the equipment. Meanwhile, the buffer structure can make the molding process more stable, avoiding excessive squeezing or damage to the hydraulic support top beam side plate a caused by excessive impact force, thus improving the accuracy and quality of molding.

[0050] Example 3: Based on Example 1, combined with Figure 9 As shown, in this embodiment, the surface of the pressure roller 220 is provided with a frosted sleeve 221. The frosted sleeve 221 can increase the friction between the pressure roller 220 and the hydraulic support top beam side plate a. When the pressure roller 220 rolls on the surface of the hydraulic support top beam side plate a, it simultaneously polishes the surface of the hydraulic support top beam side plate a, so that the old paint or impurities on the hydraulic support top beam side plate a can be removed, preparing for subsequent recoating of anti-rust paint.

[0051] Example 4: Based on Example 1, combined with Figure 10 As shown in this embodiment, the surface of the pressure roller 220 is provided with an anti-slip structure, specifically an anti-slip groove 222, which can increase the friction between the pressure roller 220 and the hydraulic support top beam side plate a, prevent the hydraulic support top beam side plate a from sliding during the pressing process, and ensure the stability and accuracy of the pressing.

[0052] It should be noted that the axial length of the pressure roller 220 is designed and manufactured according to actual operational requirements.

[0053] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
