Abstract
Description
Technical Field
[0001] This utility model relates to the field of valve disassembly and assembly technology, and in particular to a valve disassembly and assembly fixture and fixture assembly. Background Technology
[0002] Large valves are bulky and heavy, posing significant challenges to transportation and disassembly in complex, space-constrained construction environments where large hoisting equipment cannot be used. Currently, traditional hoisting equipment or simple support fixtures are commonly used for hoisting large valves on and off machines, such as directly binding the valves with a crane and flexible slings. However, these existing technologies have significant drawbacks in practical applications: First, the flexible hoisting method, lacking rigid constraints, is susceptible to a pendulum effect due to inertia during horizontal movement, resulting in excessive valve sway (measured to ±15cm). This not only affects positioning accuracy but also poses serious safety hazards. Utility Model Content
[0003] The main purpose of this utility model is to propose a valve disassembly and assembly fixture, which aims to solve the safety hazards that exist when disassembling and assembling existing large valves.
[0004] To achieve the above objectives, this utility model proposes a valve disassembly and assembly fixture for assisting in the disassembly and assembly of a valve. The valve includes a housing and a valve body. The valve disassembly and assembly fixture includes a sliding assembly, which includes a slide rail and a slider configured to slide only in the vertical direction on the slide rail. The slide rail is detachably disposed on the side of the housing, and at least a portion of the slide rail protrudes from the housing in the vertical direction. The slider has a connecting portion on the side facing the housing, which is used for detachable connection with the valve body. The slider and the connecting portion are configured to drive the valve body to move in the vertical direction under the action of external force, so as to disassemble and assemble the valve body from the housing.
[0005] In one embodiment, the slide rail includes a first plate, a second plate, and a third plate connecting the first plate and the second plate, the third plate being disposed between the first plate and the second plate, and the first plate, the second plate, and the third plate forming two slide grooves opening to opposite sides.
[0006] In one embodiment, the slider is frame-shaped, and a pulley is provided on the inner wall surface of the slider corresponding to the bottom of the groove, and the pulley is slidably disposed in the groove.
[0007] In one embodiment, there are two pulleys, and the two pulleys are slidably disposed in the two grooves.
[0008] In one embodiment, a pawl is provided in the groove;
[0009] The slider is frame-shaped, and the inner side of the slider is provided with a ratchet that matches the pawl.
[0010] In one embodiment, the slider is further provided with a lifting part for connecting to external lifting equipment.
[0011] In one embodiment, there are two lifting units, which are spaced apart in the vertical direction.
[0012] In one embodiment, the number of sliding components is two sets, and the two sets of sliding components are disposed on opposite sides of the housing in the left-right direction.
[0013] In one embodiment, the housing is provided with buffer fasteners on opposite sides in the left-right direction, and the buffer fasteners are used to be detachably connected to the slide rail by fasteners.
[0014] This utility model also proposes a fixture assembly, including a trolley and a valve disassembly and assembly fixture as described in the above embodiments, wherein the trolley is used to cooperate with the valve disassembly and assembly fixture to transfer the valve.
[0015] The technical solution of this utility model allows users to assemble or disassemble the valve by first fixing the slide rail in the sliding assembly to one side of the valve housing, then installing the valve body on the connecting part of the slider. After that, external force can be applied to the slider or the valve body so that the valve body can move smoothly up and down under the sliding cooperation of the slider and the slide rail. This effectively prevents the valve body from pendulum-like movement during movement, which could lead to inaccurate alignment with the housing, and reduces safety hazards during installation.

[0027] Large valves are bulky and heavy, posing significant challenges to transportation and disassembly in complex, space-constrained construction environments where large hoisting equipment cannot be used. Currently, traditional hoisting equipment or simple support fixtures are commonly used for hoisting large valves on and off machines, such as directly binding the valves with a crane and flexible slings. However, these existing technologies have significant drawbacks in practical applications: First, the flexible hoisting method, lacking rigid constraints, is susceptible to a pendulum effect due to inertia during horizontal movement, resulting in excessive valve sway (measured to ±15cm). This not only affects positioning accuracy but also poses serious safety hazards.
[0028] It is worth mentioning that large valves generally include a mounting base and a valve body. The mounting base is mainly a seat that is installed on the workbench or work surface and is used to install the valve body. The mounting base can be shell-shaped or frame-shaped. There are no major restrictions on this. For ease of explanation, the following description will use the shell as the mounting base.
[0029] This utility model proposes a valve disassembly and assembly fixture, which is mainly used for auxiliary installation of large valve equipment.
[0030] Please see Figures 1 to 4 In one embodiment of this utility model, the valve disassembly and assembly fixture is used to assist in the disassembly and assembly of a valve. The valve includes a housing and a valve body 9. The valve disassembly and assembly fixture includes a sliding assembly S. The sliding assembly S includes a slide rail 3 and a slider 4 configured to slide only in the vertical direction on the slide rail 3. The slide rail 3 is detachably disposed on the side of the housing, and at least a portion of the slide rail 3 protrudes from the housing in the vertical direction. The slider 4 has a connecting part 7 on the side facing the housing. The connecting part 7 is used to detachably connect with the valve body 9. The slider 4 and the connecting part 7 are configured to drive the valve body 9 to move in the vertical direction under the action of external force, so as to disassemble and assemble the valve body 9 from the housing.
[0031] The technical solution of this utility model utilizes a sliding assembly S to install the valve body 9 of the valve into the housing. In this embodiment, the sliding assembly S includes a slide rail 3 and a slider 4 configured to slide only in the vertical direction on the slide rail 3. It should be noted that one of the slider 4 and the slide rail 3 has a limiting protrusion, and the other has a limiting groove. The limiting protrusion and the limiting groove are compatible, allowing the slider 4 to slide vertically relative to the slide rail 3, but restricting its rotation relative to the slide rail 3. For example, at least one groove can be provided on the slide rail 3, and at least one protrusion can be provided on the slider 4 corresponding to the groove to achieve the aforementioned function of the slider 4. In this embodiment, the slide rail 3 needs to be detachably installed on the side of the housing. The detachable method can utilize high-strength bolts, or it can utilize snap-fit components that are easy to install and remove while also possessing high strength; no further limitations are imposed on this. It should be noted that in this embodiment, at least a portion of the slide rail 3 protrudes from the outer casing in the vertical direction, that is, at least a portion of the slide rail 3 protrudes from the end of the outer casing in the upward or downward direction. The slider 4 can slide on the portion of the slide rail 3 that protrudes from the outer casing. After the slide rail 3 is fixedly installed to one side of the outer casing, the user can also use a detachable method to fix the valve body 9 and the connecting part 7 of the slider 4. In this embodiment, the connecting part 7 can be the part of the slider 4 that protrudes towards the outer casing. It is mainly used for fixing the valve body 9. The specific shape design of the connecting part 7 can be adapted to the shape of the valve body 9. Therefore, the specific shape of the connecting part 7 is not limited. After the valve body 9 is connected to the slider 4 through the connecting part 7, the user can push the valve body 9 or the slider 4 upward or downward manually or using a hoisting tool or a lifting tool. That is, in the scenario where the user applies external force, the object of the applied external force can be the valve body 9, the slider 4, or both the valve body 9 and the slider 4. The direction of movement of the valve body 9 depends on the direction of the external force. When the slider 4 and / or valve body 9 move under the influence of an external force, the movement trajectory of the valve body 9 will be relatively stable in the vertical direction with the cooperation of the slider 4 and the slide rail 3. There will be no pendulum-like movement during the movement of the valve body 9, allowing it to move more accurately to the top or bottom of the housing via the sliding assembly S before being fixed in place. This design allows users to first fix the slide rail 3 in the sliding assembly S to one side of the valve housing when assembling or disassembling the valve, then install the valve body 9 on the connecting part 7 of the slider 4. Afterwards, an external force can be applied to the slider 4 or valve body 9, causing the valve body 9 to move smoothly in the vertical direction under the sliding cooperation of the slider 4 and the slide rail 3. This effectively prevents the valve body 9 from pendulum-like movement that could lead to inaccurate alignment with the housing, and reduces potential safety hazards during installation.
[0032] In one embodiment, the slide rail 3 includes a first plate 31, a second plate 32, and a third plate 33 connecting the first plate 31 and the second plate 32. The third plate 33 is disposed between the first plate 31 and the second plate 32. The first plate 31, the second plate 32, and the third plate 33 form two grooves 34 opening to opposite sides. To enable the slider 4 to move more smoothly up and down along the slide rail 3 and to avoid rotation relative to the slide rail 3, for example, Figure 1 As shown, in this embodiment, the slide rail 3 includes a first plate 31, a second plate 32, and a third plate 33. The first plate 31 and the second plate 32 are arranged opposite to each other, while the third plate 33 is disposed between them and connected to them respectively. The first plate 31, the second plate 32, and the third plate 33 form two sliding grooves 34 that open to opposite sides, meaning that the slide rail 3 has an "I"-shaped cross-section in the horizontal direction. This arrangement of the slide rail 3 creates at least one limiting groove as described in the above embodiment. In this embodiment, the limiting groove is a sliding groove 34, and there are two sliding grooves 34. In this embodiment, the slide rail 3 can be partially embedded in one or both of the two sliding grooves 34; this is not strictly limited. In this embodiment, by setting the slide rail 3 in this way, not only can the structural strength of the slide rail 3 itself be effectively improved, but the rotation of the slider 4 relative to the slide rail 3 can also be effectively prevented. This allows the slider 4 to drive the valve body 9 to slide in the up and down direction more stably through the slide rail 3 without rotation, thereby enabling the valve body 9 to be more accurately aligned and connected with the outer shell.
[0033] In one embodiment, the slider 4 is frame-shaped, and a pulley 8 is provided on the inner wall surface of the slider 4 corresponding to the bottom of the groove 34. The pulley 8 is slidably disposed within the groove 34. To enable the slider 4 to better cooperate with the slide rail 3, for example, Figure 1 , Figure 2 as well as Figure 3 As shown, in this embodiment, the slider 4 is directly frame-shaped and fits directly onto the outer periphery of the slide rail 3. To reduce friction between the slider 4 and the slide rail 3 when sliding, a pulley 8 is provided on the inner side of the slider 4, that is, on the inner wall of the groove bottom of the slide groove 34. The pulley 8 is rotatably disposed inside the slider 4, meaning it can directly act on the bottom of the groove 34 and roll into contact with it. This configuration not only strengthens the connection between the slider 4 and the slide rail 3, but also reduces friction with the slide rail 3 through the pulley 8, allowing the slider 4 to slide more smoothly through the slide rail 3. This enables the slider 4 to better cooperate with the slide rail 3 to move the valve body 9 in the vertical direction.
[0034] In one embodiment, there are two pulleys 8, each slidably disposed within a separate groove 34. Since there are two grooves 34, to make the sliding effect between the slider 4 and the slide rail 3 smoother, in this embodiment, two pulleys 8 are used, each disposed within a separate groove 34, meaning the two pulleys 8 are respectively disposed on opposite inner wall surfaces of the slider 4. This arrangement further strengthens the sliding connection between the slider 4 and the slide rail 3.
[0035] In one embodiment, a pawl is provided within the slide groove 34; the slider 4 is frame-shaped, and a ratchet is provided on the inner side of the slider 4 corresponding to the pawl. To ensure the overall safety of the slider 4 in case of accidental action, a ratchet is added to the slider 4 in this embodiment, and a pawl (not shown in the figure) is provided on the inner wall of the slide rail 3, that is, a ratchet is provided within the slide groove 34 of the slide rail 3. This arrangement can prevent the equipment from falling accidentally due to operational errors or sudden situations. This mechanism provides an additional locking function in the slide rail 3 system. When the slider 4 is out of control, the ratchet and pawl can automatically intervene, enhancing the stability and reliability of the system, and is especially suitable for the installation and disassembly of precision equipment.
[0036] In one embodiment, the slider 4 is further provided with a lifting part 5, which is used to connect with external lifting equipment. To facilitate the lifting and installation of the valve body 9 using external lifting equipment, such as... Figure 2 As shown, in this embodiment, a lifting part 5 is provided on the slider 4. The lifting part 5 can be provided on other outer surfaces besides those where the connecting part 7 is provided, preferably on the opposite side surface to where the connecting part 7 is provided. This arrangement facilitates the connection of external lifting equipment to the lifting part 5 via flexible slings. In this embodiment, the lifting part 5 can be a lifting ring or a lifting hook, without much limitation. Furthermore, the lifting part 5 can be integrally formed with the slider 4, again without much limitation.
[0037] In one embodiment, there are two lifting sections 5, which are spaced apart vertically. To ensure a smoother lifting connection between the external lifting equipment and the valve body 9 via the slider 4 through the lifting sections 5, as follows... Figure 2 As shown, in this embodiment, there are two lifting parts 5. The two lifting parts 5 are arranged at intervals along the vertical direction on the slider 4. This arrangement is intended to strengthen the lifting connection between the lifting equipment and the slider 4 via the flexible sling, and to prevent axial displacement of the lifting equipment when using the flexible sling to lift and connect the slider 4 and the valve body 9 due to the increase in the number of lifting parts 5. This allows the lifting equipment to more stably lift the slider 4 and the valve body 9 via the two lifting parts 5.
[0038] In one embodiment, there are two sets of sliding components S, which are located on opposite sides of the housing in the left-right direction. To enable the valve assembly / disassembly fixture to more smoothly assemble and disassemble the valve, in this embodiment, the number of sliding components S is set to two sets, with the two sets of sliding components S respectively located on the left and right sides of the housing. This arrangement not only strengthens the pendulum restraint force of the sliding components S on the valve body 9, but also improves the accuracy of the sliding components S in assembling and disassembling the valve.
[0039] In one embodiment, the outer casing is provided with buffer fasteners 6 on opposite sides along the left-right direction. The buffer fasteners 6 are detachably connected to the slide rail 3 via fasteners. To further improve the stability of the valve assembly / disassembly fixture, such as... Figure 4 As shown, in this embodiment, buffer fasteners 6 are provided on the left and right sides of the outer casing. These buffer fasteners 6 can reduce the impact of the slide rail 3 in the sliding assembly S on the outer casing, thereby indirectly improving the stability of the valve assembly and disassembly fixture. The buffer fasteners 6 can be rubber pads or silicone pads, and there are no particular limitations on this. The buffer fasteners 6 can be fixed between the slide rail 3 and the outer casing when they are fixedly connected, or they can be set between them by adhesive bonding. Again, there are no particular limitations on this.
[0040] This utility model also proposes a jig assembly, which includes a trolley 2 and a valve disassembly and assembly jig. The specific structure of the valve disassembly and assembly jig is as described in the above embodiments. Since this jig assembly adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here. The trolley 2 can be used for transporting the valve body 9 during disassembly or assembly. For example, when the valve body 9 needs to be installed on the housing, the user can use the trolley 2 to move the valve body 9 to the bottom of the housing, and then use tools to fix the valve body 9 to the connection part 7 of the slide rail 3, and then align it with the housing by hoisting. As another example, when the valve body 9 needs to be removed from the housing, the user can place the trolley 2 under the valve body 9, and then lower the valve body 9 onto the trolley 2 via the slider 4, and then disassemble the connection between the slider 4 and the valve body 9. After disassembly, the trolley 2 is used to transport the valve body 9 to a predetermined location.
[0041] In all the above embodiments, the slide rail 3 and the slider 4 are made of high-strength steel or alloy materials or other high-strength metal materials. No further limitations are imposed on this.
[0042] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made under the technical concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
