Description

Technical Field

[0001] The utility model belongs to the technical field of ash discharge valve disassembly, and particularly relates to a tooling vehicle for disassembling ash discharge valves. Background Art

[0002] In cigarette factories, dust removal equipment primarily provides wind power for the corresponding rolling and packaging equipment and tobacco-making equipment. The dust collector is a fully automatic reverse pulse jet flat bag dust collector. After dust-laden air enters the dust collection chamber, dust adheres to the surface of the filter bags, where it accumulates and forms a dust layer. When the dust layer reaches a certain level, the pulse valves activate sequentially, and the nozzles sequentially spray the filter bags, causing the bags to rapidly expand and vibrate, releasing dust that falls into the hopper.

[0003] The ash discharge valve is installed below the hopper. The upper portion of the valve receives the falling ash and smoke. The rotating impeller not only conveys the material but also acts as a seal, preventing air from being drawn in through the discharge port during pneumatic conveying, ensuring proper discharge from the dust collector. As a special type of discharge equipment, the ash discharge valve plays a significant role in dust collection.

[0004] A malfunctioning ash discharge valve can cause the dust collector unit to stop operating, which in turn causes the winding or silk-making equipment to stop functioning, requiring a quick repair to ensure continued production. When a malfunctioning ash discharge valve requires complete replacement, the spare valve must first be brought to the site, the faulty valve removed, and the spare installed. Because the ash discharge valve is heavy and lacks a lifting assist device, disassembly and assembly requires the collaboration of four maintenance workers, a process that takes 40-50 minutes. Furthermore, the site is cramped, with a large number of maintenance personnel, and there is a certain risk of injury during disassembly.

[0005] The ash unloading valve special disassembly tooling trolley is mainly used for transporting, supporting and improving work efficiency during the disassembly and assembly process of the ash unloading valve, so that the ash unloading valve can be disassembled and assembled quickly and labor-savingly. Utility Model Content

[0012] Furthermore, the lifting mechanism includes a telescopic shaft, a support shaft horizontally arranged at the top end of the telescopic shaft, sprockets arranged at both ends of the support shaft, and a transmission belt arranged on the sprocket. The direction of the support shaft is parallel to the base beam, one end of the transmission belt is fixed to the base beam, and the other end of the transmission belt is fixed to the sinking plate after being wound around the sprocket; the lifting mechanism drives the telescopic shaft to rise and fall, so that the sprockets at both ends of the support shaft rise and fall synchronously, thereby causing the transmission belt to lift or lower the sinking plate.

[0013] Furthermore, it also includes a guide column and a guide assembly. The guide column is arranged on the frame. The guide column includes two columns and a crossbeam. The two guide assemblies are respectively slidably arranged on the two columns.

[0025] To more clearly illustrate the embodiments of the present invention and the technical solutions in the prior art, the following describes specific embodiments of the present invention with reference to the accompanying drawings. Obviously, the drawings described below are merely examples of the present invention. A person skilled in the art can, without inventive effort, derive other drawings and other embodiments from these drawings. Furthermore, design orientations only represent relative positional relationships between components, not absolute positional relationships.

[0026] The embodiment of the utility model provides a tooling vehicle for disassembling the ash discharge valve, see Figure 1 、 Figure 2 、 Figure 3 It mainly includes a frame 1, a lifting platform 2 for carrying an ash unloading valve, and a tool box 3. The frame 1 includes two parallel forks 11 and a base beam 13. The base beam 13 is placed horizontally in the middle of the two forks 11. The tool box 3 is mounted on the frame 1 on the rear side of the base beam 13. The lifting platform 2 is provided on the base beam 13. The lifting platform 2 is provided with a liftable fork arm 21 in front of the base beam 13, and the fork arm 21 is located between the two forks 11 when it drops to the lowest position.

[0027] In the present application, the lifting support of the ash unloading valve can be achieved by the fork arm 21. The lifting platform 2 may include two fork arms 21 arranged in parallel. A carrier plate 211 may be arranged between the two fork arms 21. The main support of the ash unloading valve can be provided by the fork arm, and the carrier plate 211 is used for stability support to prevent the ash unloading valve from tipping forward or falling.

[0028] For example, the length of the carrier plate 211 can be close to the length of the fork arm 21, so that the front end of the carrier plate 211 is flush with the fork arm 21. When the fork arm 21 supports the ash unloading valve, the carrier plate 211 can simultaneously support the ash unloading valve to fall stably on the lifting platform 2, and then rise and fall to assist in completing the disassembly operation.

[0029] In this application, the frame 1 is divided into the front and rear ends by the base beam 13. The front end is provided with a lifting platform 2 and the rear end is provided with a toolbox 3. When the lifting platform 2 is loaded with an ash unloading valve, the toolbox 3 at the rear end can effectively stabilize the balance of the entire vehicle based on the lever principle.

[0030] Exemplarily, the tool box 3 may be a box structure, located on the rear end structure of the frame 1, and may implement functions such as accommodating, storing, and placing, such as accommodating counterweights, storing tools, and placing tools.

[0031] In a specific embodiment, the toolbox 3 may include a placement platform on the top, a drawer 31 that is pulled out backward, and a storage cavity provided under the drawer 31. The storage cavity is provided with an opening and closing door 32 that opens backward. The drawer 31 is provided under the placement platform, and an armrest 7 is provided at the rear end of the placement platform.

[0032] Among them, the edge of the placement platform can be equipped with an anti-fall structure to prevent tools from rolling down; the drawer 31 can accommodate some commonly used tools (such as screwdrivers, small wrenches, small calipers, etc.), and the tools can be temporarily placed on the placement platform during operation; counterweights and other slightly larger tools (such as sockets, large calipers, large wrenches, electric screwdrivers, etc.) can be placed in the accommodating cavity, and tools that cannot be placed in the drawer 31 or cannot be put in can be accommodated in the accommodating cavity.

[0033] It can be understood that the counterweight can be a relatively regular structure, so that other tools can still be placed and stored in the accommodating cavity when the counterweight exists.

[0034] In the present application, a wheeled support leg is provided between the vehicle frame 1 and the ground to facilitate the operation of the work vehicle. The fork frame 11 is a hollow structure. A fixed wheel 12 can be embedded in the front end of the fork frame 11, and a swing wheel 33 can be provided at the rear end of the fork frame 11. In order to meet the swinging requirements of the swing wheel 33, a swinging notch can be provided at the rear end of the fork frame 11 to avoid the fork frame 11 interfering with the swing of the swing wheel 33.

[0035] In this application, the lifting platform 2 is set based on the position of the base beam 13, and its main function is to realize the lifting and lowering adjustment of the ash unloading valve so that the height of the ash unloading valve meets the installation requirements, so that the operator can quickly install it; during disassembly, the lifting platform 2 is used to support the ash unloading valve, and the height should also be adjusted to meet the support requirements before disassembly.

[0036] In the embodiment of the present application, the lifting platform 2 should at least include a lifting mechanism 5, and the height adjustment of the ash discharge valve can be achieved through the lifting mechanism 5 to meet the height adjustment requirements during actual installation and disassembly.

[0037] The lifting mechanism 5 can specifically be a controllable telescopic structure such as a hydraulic cylinder, an air cylinder, a telescopic motor, etc. In this application, the hydraulic cylinder is used as an example for explanation.

[0038] The lifting mechanism 5 can be vertically arranged on the base beam 13, and the base beam 13 can have a certain width, such as Figure 2As shown in , the lifting mechanism 5 can be arranged at a front position in the middle of the base beam 13. The fork arm 21 can be connected to the lifting end of the lifting mechanism 5 in a horizontal state, so that the lifting mechanism 5 drives the fork arm 21 to move up and down.

[0039] Due to the existence of the base beam 13 , the fork arm 21 may interfere with it when descending. The fork arm 21 can be extended forward so that the lifting position of the fork arm 21 is located in front of the base beam 13 and within the two fork frames 11 .

[0040] In the embodiment of the present application, a sinking plate 24 is provided to adjust the fixing position and the lifting position of the fork arm 21 , so that the fork arm 21 can be lifted and lowered in front of the base beam 13 and within the two fork frames 11 .

[0041] The direction of the sinking plate 24 can be parallel to the base beam 13 and be installed vertically. The upper end of the sinking plate 24 is connected to the lifting end of the lifting mechanism 5, and the lower end is connected to the fork arm 21. The lifting end and the fork arm 21 are respectively arranged on both sides of the sinking plate 24. On this basis, the sinking plate 24 can be vertically located in front of the base beam 13.

[0042] like Figure 1 As shown, the upper end of the sinking plate 24 is connected to the lifting end of the lifting mechanism 5 , and the fork arm 21 is fixed to the front side of the lower end of the sinking plate 24 .

[0043] The stroke of the lifting mechanism 5 is fixed (limited). When the stroke is insufficient, the lowest position of the fork arm 21 can be extended to within the two fork frames 11 by adjusting the height of the sinking plate 24 itself.

[0044] When the sinking plate 24 descends, the fork arm 21 at the lower end of the sinking plate 24 first descends to between the two fork frames 11. If the vertical height of the sinking plate 24 itself is increased, the fork arm 21 at the lower end of the sinking plate 24 can be completely sunk within the two fork frames 11 while the height position of the upper end of the sinking plate 24 remains unchanged, so that the upper surface of the fork arm 21 is flush with the upper surface of the fork frame 11.

[0045] In actual implementation, the height of the sinking plate 24 is adapted to the height of the fork frame 11, and can be carried out when the fork arm 21 is lowered to the lowest position; the vertical height of the sinking plate 24 is at least the same as the structural height (or thickness) of the fork frame 11 to ensure that the fork arm 21 located at the lower end of the sinking plate 24 can be sunk between the two fork frames 11; preferably, the upper surface of the fork arm 21 can be flush with the upper surface of the fork frame 11; of course, if the height of the sinking plate 24 is continued to be increased, the fork arm 21 can be completely sunk below the upper surface of the fork frame 11.

[0046] It is understandable that the heights of the sinking plate 24 and the fork frame 11 refer to the dimensional data of their own structures, not the height data from the ground.

[0047] By adjusting the height of the sinking plate 24 to adapt to the extreme stroke of the lifting mechanism 5, the normal state and the operating state of the fork arm 21 can be defined. The normal state can be that the fork arm 21 sinks below or is flush with the fork frame 11; the operating state can be that the fork arm 21 rises above the fork frame 11, and the rising height can be adjusted according to actual needs.

[0048] Based on the above embodiment, it is difficult to place the sinking plate 24 in front of the base beam 13 to achieve lifting and lowering by relying solely on a single plate-like structure of the sinking plate 24. A corresponding structure can be set on the lifting mechanism 5 to adjust the position of the lifting end of the lifting mechanism 5 so that it can be located in front of the base beam 13 and directly or indirectly fixed to the sinking plate 24.

[0049] In the aforementioned embodiment, it has been clarified that the lifting mechanism 5 can be positioned in the middle and forward position of the base beam 13. However, simply positioning it in the forward position does not ensure that the lifting end of the lifting mechanism 5 is positioned in front of the base beam 13. Therefore, the lifting end can be adjusted to be positioned in front of the base beam 13 by changing the direction of the force.

[0050] In a specific embodiment, the lifting mechanism 5 may include a telescopic shaft 51, a support shaft 53 horizontally arranged at the top of the telescopic shaft 51, sprockets 52 arranged at both ends of the support shaft 53, and a transmission belt 54 arranged on the sprocket 52. The direction of the support shaft 53 is parallel to the base beam 13, one end of the transmission belt 54 is fixed to the base beam 13, and the other end of the transmission belt 54 is wound around the sprocket 52 and then fixed to the sinking plate 24; the lifting mechanism 5 drives the telescopic shaft 51 to rise and fall, so that the sprockets 52 at both ends of the support shaft 53 rise and fall synchronously, thereby causing the transmission belt 54 to lift or lower the sinking plate 24.

[0051] In this application, a sprocket 52 is mounted on the telescopic shaft 51, and the direction of the force is converted through a transmission belt 54 so that the lifting end of the lifting mechanism 5 is located in front of the base beam 13; the original external force application form of lifting / raising the sinking plate 24 is changed to the current external force application form of pulling / lifting the sinking plate 24.

[0052] It can be understood that the lifting mechanism 5 is arranged in the front, and the transmission belt 54 can be suspended in front of the paper base beam 13 through the expansion support of the sprocket 52, and fixed to the sinking plate 24; Figure 2 As shown in the figure, the dotted line shows the boundary of the base beam 13, and the transmission belt 54 is located in front of the base beam 13; continuing to increase the size of the sprocket 52 can extend the transmission belt 54 forward, farther away from the boundary of the base beam 13, thereby meeting the lifting requirements of the sinking plate 24.

[0053] Exemplarily, the transmission belt 54 can be a chain, the sprocket 52 is provided with gear teeth, the chain is engaged on it, and the sprocket 52 is rotationally connected to the bracket shaft 53; when the telescopic shaft 51 rises / falls, the sprocket 52 rotates synchronously, causing the length of the chain on the right side of the sprocket 52 to change, thereby realizing the raising / lowering drive of the sinking plate 24.

[0054] For example, the front end of the chain is fixed to the base beam 13, the chain is wound on the sprocket 52, and its end can be fixed to the sinking plate 24. The end of the chain is the lifting end of the lifting mechanism 5; the length of the chain matches the vertical dimension of the sinking plate 24. When the telescopic shaft 51 is fully retracted, the fork arm 21 drops to the lowest position, that is, the fork arm 21 is flush with the fork frame 11.

[0055] In this application, a bracket shaft 53 is provided at the upper end of the telescopic shaft 51, and two sprockets 52 are set up at both ends of the bracket shaft 53. The sinking plate 24 is evenly lifted / lowered through a double transmission belt 54. On this basis, the lifting and lowering trajectory of the sinking plate 24 should also be restricted to make the lifting and lowering position of the sinking plate 24 stable, thereby ensuring the lifting and lowering stability of the fork arm 21.

[0056] In the embodiment of the present application, a guide column 4 may be provided on the vehicle frame 1 to limit and guide the lifting trajectory of the sinking plate 24 so that it can be lifted and lowered stably.

[0057] As an embodiment, two guide columns 4 can be provided on the vehicle frame 1 , and a slidable guide assembly 23 can be provided on the guide columns 4 . The sinking plate 24 is fixed to the guide assembly 23 , and the guide columns 4 can ensure the descending stability of the sinking plate 24 .

[0058] In this case, the guide column 4 can be specifically arranged on the base beam 13, and the two guide columns 4 are respectively located on both sides of the lifting mechanism 5. The guide assembly 23 should have a certain length, one end is slidably connected to the guide column 4, and the other end is fixed to the inner side surface of the sinking plate 24, and the fixed position is relatively high; and the fork arm 21 is fixed to the outer side of the sinking plate 24, and is in a horizontal state forward.

[0059] As another embodiment, the guide column 4 can be a frame structure, including two columns and a crossbeam. The crossbeam is fixed to the upper ends of the two columns to stabilize the overall structure of the guide column 4 and ensure the structural stability of the individual columns. A guide assembly 23 is provided on each column, and the ends of the sinking plate 24 are respectively fixed to the two guide assemblies 23. When the sinking plate 24 is hoisted or lowered, it always moves along the direction of the columns.

[0060] As a preferred embodiment, a hanging beam 22 can be provided on the sinking plate 24, the transmission belt 54 is fixedly connected to the hanging beam 22, and the sinking plate 24 is fixedly connected under the hanging beam 22, and the guide assembly 23 can be fixedly connected to the hanging beam 22 and / or the sinking plate 24.

[0061] Exemplarily, the hanging beam 22 is fixed to the top of the sinking plate 24 , the transmission belt 54 is fixed to the hanging beam 22 , and both ends of the hanging beam 22 are fixed to the two guide assemblies 23 respectively.

[0062] Available, see Figure 2 The guide column 4 can be arranged on the fork frame 11, the length of the hanging beam 22 spans the two fork frames 11, the two ends of the hanging beam 22 are respectively fixed to the guide components 23 on the two guide columns 4, and the sinking plate 24 is located in the middle of the hanging beam 22 and is equipped with the fork arm 21.

[0063] It should be clear that the length of the sinking plate 24 should still be limited to the distance between the two fork frames 11 , that is, the length of the sinking plate 24 is less than the distance between the two fork frames 11 .

[0064] Of course, the upper length of the sinking plate 24 can be greater than the lower length, so that the lower length of the sinking plate 24 is still limited between the two forks 11, and the upper length is the same as the length of the hanging beam 22. At this time, the guide assembly 23 can be fixedly connected to the sinking plate 24.

[0065] Based on the above embodiment, the carrier plate 211 can be disposed based on the sinking plate 24 , and the carrier plate 211 can be located between the two fork arms 21 .

[0066] In the embodiment of the present application, on the basis of setting the guide column 4 to limit the lifting trajectory of the sinking plate 24, the outward expansion effect of the sprocket 52 on the transmission belt 54 can be ignored, but the normal driving requirements of the sprocket 52 should be maintained; the lifting position of the sinking plate 24 can be adjusted by adjusting the setting position of the guide column 4, so that the sinking plate 24 is located in front of the base beam 13, rather than relying solely on the size of the sprocket 52. In this case, the matching relationship between the sprocket 52 and the chain can be equivalently replaced, such as a pulley, a steel rope, etc.; at the same time, the installation posture of the lifting mechanism 5 is not strictly required to be in a vertical state, and it is sufficient to be able to pull the sinking plate 24. When lowering, it can be automatically reset by the cooperation of gravity.

[0067] In the embodiment of the present application, the guide assembly 23 is arranged based on the guide column 4, and its purpose is to ensure that the running position of the sinking plate 24 is stable without shaking or offset. Therefore, the guide assembly 23 can be a simple matching relationship between the aperture and the column. Of course, in order to reduce friction, the aperture can be polished smooth, and rollers can be configured to facilitate sliding; the guide assembly 23 can also be a matching relationship between the roller and the column; of course, at least two guide assemblies 23 are required to determine the running trajectory of the sinking plate 24. In the embodiment of the present application, two guide assemblies 23 are set as an example for illustration and explanation.

[0068] In a specific embodiment, the guide column 4 can be a cylindrical structure, and the guide assembly 23 can include an outer shell and a set of guide wheels 6 symmetrically arranged in the outer shell. The guide wheels 6 are provided with arc-shaped grooves 61. The grooves 61 are annular on the guide wheels 6 and are opened in the middle of the guide wheels 6. The distance between the two grooves 61 is the same as the diameter of the column, so that the guide column 4 can be just located between the two guide wheels 6 and is clamped by the two oppositely arranged grooves 61. Figure 3 As shown in .

[0069] In this application, when the guide assembly 23 is combined with structures other than the guide column 4, it is in a fixed form, can be detachable, and can be fixed based on the outer shell; the sinking plate 24 and / or the hanging beam 22 are fixed to the outer shell of the guide assembly 23.

[0070] With the structural coordination of the guide assembly 23 and the guide column 4, the hanging beam 22 is horizontally placed above the fork frame 11, and the end of the chain is fixed thereto, so the fork arm 21 cannot be directly lowered to a position flush with the fork frame 11. Therefore, the fork arm 21 is carried by the lower end of the sinking plate 24, and it can be extended between the two fork frames 11 to reach the preferred position flush with the fork frame 11.

[0071] When using the work vehicle of this application:

[0072] During the installation of the ash unloading valve, the ash unloading valve is placed on the fork arm 21, and the work vehicle is pushed to the vicinity of the installation position. The hydraulic cylinder is manually pressurized, and the piston (telescopic shaft) of the hydraulic cylinder rises, driving the sprocket chain mechanism fixed on the top of the piston to move. The sprocket rotates counterclockwise to drive the chain to move counterclockwise. The chain drives the fork arm to rise along the guide column through the guide assembly, and the fork arm 21 drives the ash unloading valve to rise. During this process, the carrier plate 211 supports the stability of the ash unloading valve. After the ash unloading valve reaches the installation height, stop the manual pressurization of the hydraulic cylinder, and send the ash unloading valve to the installation position for installation. After the installation is completed, remove the work vehicle and manually depressurize the hydraulic cylinder. The piston of the hydraulic cylinder falls back, and the fork arm 21 and the carrier plate 211 return to normal state.

[0073] During the disassembly of the ash unloading valve, the work vehicle is pushed to the vicinity of the disassembly position, and the hydraulic cylinder is manually pressurized. The piston of the hydraulic cylinder rises, driving the sprocket chain mechanism fixed on the top of the piston to move. The sprocket rotates counterclockwise, driving the chain to move counterclockwise. The chain drives the fork arm to rise upward along the guide column through the guide assembly. The fork arm and the carrier plate rise synchronously. After reaching the support position of the ash unloading valve, the manual pressurization of the hydraulic cylinder is stopped, and the work vehicle is sent to the support position for support. After the disassembly is completed, the work vehicle is removed and the hydraulic cylinder is manually depressurized. The piston of the hydraulic cylinder falls back, driving the fork arm 21 and the carrier plate 211 to fall synchronously, so that the ash unloading valve on it falls to the ground.
