Description

Technical Field

[0001] This utility model relates to the field of disassembly and assembly equipment technology, and in particular to a vertical disassembly and assembly equipment for hydraulic support columns. Background Technology

[0002] As the core load-bearing component of the hydraulic support in a fully mechanized coal mining face, the hydraulic support column is subjected to harsh working conditions of high pressure, strong impact, and high dust for a long time. It is prone to failures such as seal failure and cylinder wear, and needs to be disassembled and repaired regularly to ensure the safety of fully mechanized mining operations.

[0003] Current column dismantling and assembly equipment in the industry has some drawbacks: traditional horizontal equipment requires the column to be placed horizontally, which not only occupies a lot of space and is cumbersome to operate, but also easily causes internal impurities to flow and contaminate the parts; although vertical devices improve the space problem, they lack an effective protective structure, and small fragments generated during dismantling can easily fly out and injure people, and are not easy to clean. Secondly, the positioning and clamping mechanisms are mostly fixed in size, making it difficult to adapt to columns of different diameters, requiring frequent clamp replacements, which seriously affects dismantling efficiency. Therefore, in order to address the above problems, a hydraulic support column vertical dismantling and assembly equipment is proposed. Utility Model Content

[0004] To overcome the problems existing in related technologies, this utility model provides a vertical disassembly and assembly device for hydraulic support columns. The transparent cover can effectively block small fragments from splashing during disassembly operations, and the annular airbag at the bottom of the transparent cover can prevent fragments from splashing out from the gap between the transparent cover and the column, and can also form a certain sealing effect on the disassembly area, reducing the leakage of hydraulic oil, dust and other substances.

[0005] To achieve the above objectives, this utility model provides a hydraulic support column vertical assembly and disassembly device, including an L-shaped frame, on which a liftable mounting plate is mounted, and on the mounting plate a rotating component for driving the column components to rotate, and further comprising: A blocking member connected to the rotating member, the blocking member having a liftable stop bar; The transparent cover is connected to the second telescopic component. The transparent cover is raised and lowered through the second telescopic component so that small fragments generated during the disassembly of the column can be blocked from splashing out when the column is disassembled. The bottom of the transparent cover is provided with an annular airbag. The airbag can be inflated by an external inflation device and expand towards the center of the transparent cover, so that the inner ring of the airbag fits the outer wall of the column with different diameters.

[0006] Preferably, the airbag is connected to an air delivery hose, and the upper end face of the airbag is also provided with a delivery groove, and the bottom end of the delivery groove is provided with a guide hole.

[0007] Preferably, the second telescopic member includes: A surrounding panel is attached to the outside of the vertical frame of the L-shaped frame, and the surrounding panel is connected to the transparent cover; The second telescopic rod is installed on the transverse frame of the L-shaped frame, and the top end of the second telescopic rod is connected to the enclosure panel.

[0008] Preferably, the inner wall of the enclosure is fixed with guide strips, and the vertical frame outer wall of the L-shaped frame is provided with guide grooves.

[0009] Preferably, the rotating member includes: The motor is mounted on the mounting plate; A screwdriver head is installed at the bottom end of the motor shaft.

[0010] Preferably, the blocking member includes: A protruding plate is vertically fixed to the bottom shaft of the motor; The first telescopic rod is installed through the convex plate, and the stop bar is installed at the bottom end of the first telescopic rod; A protrusion is fixed to the outside of the screw head, and the stop bar passes through the protrusion.

[0011] The technical solution provided by this utility model can include the following beneficial effects: 1. In this example, the transparent cover can effectively block small fragments from splashing during disassembly, ensuring the personal safety of the operators without affecting their observation of the disassembly process and avoiding operational errors caused by obstructed vision. 2. In this example, the annular airbag at the bottom of the transparent cover can be inflated by an external inflation device to fit the outer wall of columns of different diameters. On the one hand, it further prevents fragments from splashing out from the gap between the transparent cover and the column. On the other hand, it can form a certain sealing effect on the disassembly area, reduce the leakage of hydraulic oil, dust and other substances, and improve the working environment. 3. In this example, when the stop bar in the blocking component is used in conjunction with the auxiliary plate, it can handle the ends of columns with special specifications or severe surface wear that need to be disassembled. By selecting a matching auxiliary plate and utilizing the torque transmitted by the stop bar, the disassembly of non-standard column components can be achieved, breaking through the size limitations of traditional screwdrivers and further expanding the applicability of the equipment.

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model 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 this utility model, and not all of them. All other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. The preferred embodiments of this utility model will now be described in more detail with reference to the accompanying drawings. Although preferred embodiments of this utility model are shown in the drawings, it should be understood that this utility model can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to make this utility model more thorough and complete, and to fully convey the scope of this utility model to those skilled in the art.

[0016] The technical solutions of the embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0017] See Figures 1-5As shown, this utility model provides a hydraulic support column vertical disassembly and assembly device, including an L-shaped frame 1. The L-shaped frame 1 is welded from high-strength alloy steel. Its horizontal frame body serves as the equipment base, and adjustable anchor bolts are provided at the bottom to calibrate the equipment's level and enhance its placement stability. The vertical frame body is a vertical load-bearing structure. Clamping components can also be installed on the horizontal frame body to clamp the lower end of the column to be disassembled. A vertical first telescopic component 2 is installed on the vertical frame body of the L-shaped frame 1. The first telescopic component 2 is a hydraulic cylinder, and an mounting plate 3 is installed at the bottom end of the first telescopic component 2. A rotating mechanism for driving the column components to rotate is installed on the mounting plate 3. The moving part 4 also includes a blocking part 5, a transparent cover 6, and a second telescopic part 7. The blocking part 5 is connected to the rotating part 4 and has a liftable stop bar 53. The transparent cover 6 is made of polycarbonate sheet and has the characteristics of high strength, impact resistance and good light transmission. The transparent cover 6 is raised and lowered through the second telescopic part 7 so as to prevent small fragments generated during the disassembly of the column from splashing out when the column is disassembled. The bottom of the transparent cover 6 is provided with an annular airbag 61. After the airbag 61 is inflated by an external inflation device, it can expand towards the center of the transparent cover 6, so that the inner ring of the airbag 61 fits the outer wall of the column with different diameters.

[0018] Among them, see Figure 1 and Figure 2 As shown, the rotating component 4 includes a motor 41 and a screw head 42. The motor 41 is mounted on the mounting plate 3. The screw head 42 is made of high-hardness alloy material and is mounted on the bottom shaft end of the motor 41. The screw head 42 is used to engage with the column component to be disassembled. The motor 41 drives the screw head 42 to rotate in order to disassemble the column component.

[0019] See Figure 5 As shown, an air supply hose 62 is connected to the airbag 61. The end of the air supply hose 62 away from the airbag 61 is connected to an external inflation device. The airbag 61 is also equipped with an exhaust pipe, on which an electric control valve is installed. The upper surface of the airbag 61 is also equipped with a guide groove 63. The bottom of the guide groove 63 is provided with a guide hole 64 that penetrates the airbag 61. The guide hole 64 is used to drain the liquid or impurities that fall onto the airbag 61. The airbag 61 is made of a soft material that is wear-resistant and impact-resistant. During the production of the airbag 61, the guide groove 63 and the guide hole 64 are integrally formed.

[0020] Furthermore, the airbag 61 can create a certain sealing effect on the disassembly area, reducing leakage of hydraulic oil, dust, etc., and improving the working environment.

[0021] Secondly, during the disassembly process, hydraulic oil, rust, and small fragments are blocked and fall onto the airbag 61. After being blown away, they can be collected from the guide groove 63 and then fall down through the guide hole 64 for collection, which can reduce the amount of cleaning work.

[0022] See Figure 5As shown, the second telescopic component 7 includes a surrounding plate 71 and a second telescopic rod 72. The surrounding plate 71 surrounds the vertical frame of the L-shaped frame 1 and is connected to the transparent cover 6. The second telescopic rod 72 is a hydraulic rod or an electric telescopic rod. The second telescopic rod 72 is installed on the horizontal frame of the L-shaped frame 1, and the top end of the second telescopic rod 72 is connected to the surrounding plate 71. A guide strip 73 is fixed on the inner wall of the surrounding plate 71. A guide groove is provided on the outer wall of the vertical frame of the L-shaped frame 1. When the second telescopic rod 72 is activated, the surrounding plate 71 can be raised and lowered, which in turn raises and lowers the transparent cover 6. During disassembly, the transparent cover 6 can block the periphery of the disassembly end, effectively preventing small fragments from splashing and improving the disassembly and installation.

[0023] See Figure 5 As shown, the blocking component 5 includes a protruding plate 51 and a first telescopic rod 52. The first telescopic rod 52 is an electric telescopic rod. The protruding plate 51 is vertically fixed on the bottom shaft of the motor 41. The first telescopic rod 52 is installed through the protruding plate 51, and the stop rod 53 is installed at the bottom end of the first telescopic rod 52. A protrusion 54 is fixed on the outside of the screwing head 42, and the stop rod 53 passes through the protrusion 54. When facing the end of the column to be disassembled with special specifications or severe surface wear, which causes the screwing head 42 to fail to form an effective engagement, a matching auxiliary plate can be selected according to the size of the column end. The auxiliary plate is made of high-strength plastic, with a positioning hole in the middle that matches the shape of the column end, and evenly distributed around the perimeter with the stop rod 53. For the corresponding perforation 3, during operation, the auxiliary plate is fitted and attached to the end of the column to be disassembled. The controller drives the first telescopic rod 52 to extend, so that the bottom end of the stop rod 53 passes through the protrusion 54 and the perforation on the auxiliary plate. At this time, the motor 41 is started to drive the screw head 42 to rotate, so that the stop rod 53 drives the auxiliary plate to rotate synchronously. The friction and torque generated by the tight fit between the auxiliary plate and the end of the column are used to realize the disassembly operation of columns of special specifications. This breaks through the size limitation of the traditional screw head 42. Through the flexible adaptation of the auxiliary plate and the transmission action of the stop rod 53, the device can deal with column parts with a wider diameter range and more complex surface conditions, improving the versatility of the equipment and the efficiency of operation.
