Abstract
Description
Technical Field
[0001] This utility model relates to the field of transfer and lifting equipment technology, specifically to a flange valve body lifting fixture. Background Technology
[0002] Flanged ball valves consist of components such as the valve body and valve cover. During the production process, the valve body needs to be transported from the warehouse to the production workshop for assembly. Since the flange valve body lacks a dedicated lifting mechanism, it has traditionally been manually moved onto a transfer trolley during transport. This manual handling method is labor-intensive for large-volume transfers. Some technologies utilize lifting lugs on the flange valve body, employing electric hoists for lifting and transport. While this method effectively reduces labor intensity, the efficiency of lug installation and removal is low, negatively impacting production efficiency. Furthermore, because the lifting lugs are typically not centered on the flange valve body, it can only be lifted at an angle, which doesn't guarantee a stable landing on the transfer trolley and can easily lead to scratches on the outer surface of the valve body.
[0003] Therefore, it is necessary to develop and design a tooling for lifting flange valve bodies in order to reduce the labor force of workers, while ensuring the efficiency of transfer and lifting and the quality of production. Utility Model Content
[0004] In view of this, the purpose of this utility model is to provide a flange valve body lifting fixture. By adopting this lifting fixture, it is possible to reduce the labor force of workers, and at the same time, it is possible to ensure the efficiency of transfer and lifting and the quality of production.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a flange valve body lifting fixture, comprising: a base plate and a clamping mechanism disposed on the base plate for clamping the flange portion of the flange valve body in conjunction with the base plate, wherein at least two sets of the clamping mechanism are disposed along the circumference of the base plate, and a lifting part is disposed at the center of the base plate.
[0006] Furthermore, the clamping mechanism includes a base fixed on the substrate and a clamping block that can be driven to rotate and locked on the base. The clamping block has a first locking position, and when the clamping block is in the first locking position, a clamping space adapted to the flange thickness of the flange valve body is formed between the clamping block and the substrate.
[0007] Furthermore, the clamping block also has a second locking position, and when the clamping block is in the second locking position, the clamping block can avoid the flange part of the flange valve body to complete the picking and placing operation.
[0008] Furthermore, the base includes a limiting cylinder fixed to the edge of the substrate, the bottom of which is lower than the bottom surface of the substrate and is used to form a radial limit on the flange portion of the flange valve body.
[0009] Furthermore, a rotating rod is rotatably installed in the limiting cylinder, with both ends of the rotating rod passing through the upper and lower ends of the limiting cylinder respectively. The clamping block is fixed to the bottom of the rotating rod, and a position locking plate is fixed to the top of the limiting cylinder. The position locking plate is provided with a first position locking hole and a second position locking hole. A toggle plate is fixed to the top of the rotating rod, and a spring locking pin mechanism is provided on the toggle plate. The spring locking pin of the spring locking pin mechanism can be selectively inserted into the first position locking hole or the second position locking hole.
[0010] Furthermore, the rotating rod can float up and down relative to the limiting cylinder. A spring seat is fixed on the upper part of the rotating rod, and a compression spring is provided in the limiting cylinder. One end of the compression spring abuts against the spring seat, and the other end of the compression spring abuts against the bottom of the limiting cylinder.
[0011] Furthermore, the substrate is a circular plate, and the edge of the substrate extends radially outward to form a support ear, and the limiting cylinder is fixed on the support ear.
[0012] Furthermore, the clamping mechanism is evenly distributed in three groups along the circumference of the substrate.
[0013] Furthermore, the substrate is a circular plate, and an annular anti-scratch plate is fixedly provided at the bottom of the substrate.
[0014] Furthermore, the substrate is an aluminum plate, and weight-reduction holes are provided on the substrate.
[0015] Compared with the prior art, the present invention has at least the following beneficial effects:
[0016] By using the flange valve body lifting fixture provided by this utility model, stable and reliable lifting of the flange valve body can be achieved, which can reduce the labor of workers. This lifting fixture uses a clamping mechanism in conjunction with a base plate to clamp the flange part of the flange valve body. Compared with the installation lugs, the disassembly and assembly efficiency is high, which helps to ensure the lifting efficiency of transfer and hoisting. Since the lifting part is set at the center of the base plate, the flange valve body can be lifted vertically and stably during hoisting, which helps to ensure the stability when falling, and reduces the risk of scratching the flange valve body, thereby ensuring production quality.

Detailed Implementation
[0023] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that the illustrations provided in the following embodiments are only for illustrating the basic concept of this utility model. Unless otherwise specified, the following embodiments and features in the embodiments can be combined with each other.
[0024] Please see Figures 1-4This embodiment discloses a flange valve body lifting fixture, including: a base plate 1 and a clamping mechanism 2 disposed on the base plate 1 for clamping the flange portion 401 of the flange valve body 4. At least two sets of clamping mechanisms 2 are configured along the circumference of the base plate 1, and a lifting part 3 is disposed at the center of the base plate 1. Specifically, in use, the base plate 1 is attached to the top surface of the flange portion 401 of the flange valve body 4, and then the flange portion 401 is clamped by the clamping mechanism 2. The stability of clamping the flange valve body 4 can be ensured by providing at least two sets of clamping mechanisms 2. The structure of the clamping mechanism 2 is not limited here, as long as it can ensure stable clamping of the flange valve body 4. It can be understood that the flange portion 401 of the flange valve body 4 refers to the flange flange disc of the flange valve body 4. The lifting part 3 here adopts a lifting ring; of course, in other embodiments, the lifting part 3 can also adopt a hook or other structure. By adopting the flange valve body lifting fixture in the above structure, the flange valve body 4 can be lifted stably and reliably, which can reduce the labor force of workers, especially for large-scale lifting. The lifting fixture uses the clamping mechanism 2 in conjunction with the base plate to clamp the flange part 401 of the flange valve body 4. Compared with the installation lugs, the disassembly and assembly efficiency is high, which helps to ensure the lifting efficiency of transfer and lifting. Since the lifting part 3 is set at the center of the base plate 1, the flange valve body 4 can be lifted vertically and stably during lifting, which helps to ensure the stability when falling, reduces the risk of scratching the flange valve body 4, and thus ensures production quality.
[0025] In this embodiment, the clamping mechanism 2 includes a base 201 fixed on the base plate 1 and a clamping block 202 that can be driven to rotate and locked onto the base 201. The clamping block 202 has a first locking position, and when the clamping block 202 is in the first locking position, a clamping space adapted to the thickness of the flange portion 401 of the flange valve body 4 is formed between the clamping block 202 and the base plate 1. Here, "adapted" usually means that the height of the clamping space is equal to the thickness of the flange portion 401. Here, it is preferable to manually drive the clamping block 202 to rotate. By using the rotatable clamping block 202, the installation of the clamping mechanism 2 can be completed quickly. In use, when the clamping block 202 is rotated to the first locking position and locked, the flange portion 401 can be stably clamped. The clamping mechanism 2 in this structural design has a simple structure, reliable clamping of the flange valve body 4, and high installation efficiency of the lifting fixture during use.
[0026] In this embodiment, the clamping block 202 also has a second locking position. When the clamping block 202 is in the second locking position, it can avoid the flange portion 401 of the flange valve body 4 to complete the pick-and-place operation. The second locking position helps to further improve the efficiency of the lifting fixture's assembly and disassembly, while also reducing the risk of collisions and further improving production quality. Specifically, during use, rotating and fixing the clamping block 202 in the second locking position can prevent collisions between the clamping block 202 and the flange portion 401 of the flange valve body 4 due to displacement during installation or disassembly.
[0027] In this embodiment, the base 201 includes a limiting cylinder 201a fixed to the edge of the substrate 201. The bottom of the limiting cylinder 201a is lower than the bottom surface of the substrate 1 and is used to form a radial limiting of the flange portion 401 of the flange valve body 4. Specifically, the limiting cylinder 201a is welded and fixed to the substrate 201. The limiting cylinder 201a with a cylindrical structure forms a radial limiting of the flange portion 401, which can further improve the clamping stability of the flange valve body 4 and reduce the risk of the flange valve body 4 shaking.
[0028] In this embodiment, a rotating rod 203 is rotatably mounted in the limiting cylinder 201a. The two ends of the rotating rod 203 pass through the upper and lower ends of the limiting cylinder 201a, respectively. A clamping block 202 is fixed to the bottom of the rotating rod 203. A position locking plate 201b is fixed to the top of the limiting cylinder 201a. The position locking plate 201b has a first position locking hole 201b1 and a second position locking hole 201b2. A toggle plate 204 is fixed to the top of the rotating rod 203. A spring locking pin mechanism 205 is provided on the toggle plate 204. The spring locking pin 205a of the spring locking pin mechanism 205 can be selectively inserted into either the first position locking hole 201b1 or the second position locking hole 201b2. Specifically, the clamping block 202 is welded to the rotating rod 203; the position locking plate 201b is welded to the limiting cylinder 201a; and the toggle plate 204 is welded to the rotating rod 203. The spring locking pin mechanism 205 adopts an existing spring locking pin structure, which will not be described in detail here. It is understood that the first position locking hole 201b1 and the second position locking hole 201b2 correspond to the first locking position and the second locking position of the clamping block 202, respectively. In specific use, when the spring locking pin 205a is inserted into the first position locking hole 201b1, the clamping block 202 is locked in the first locking position, and the clamping block 202 and the base plate 1 clamp the flange portion 401. When the spring locking pin 205a is inserted into the second position locking hole 201b2, the clamping block 202 is locked in the second locking position, and the clamping block 202 can avoid the flange portion 401 to complete the installation or disassembly operation. The structure used in this design can reliably lock the clamping block 202 in the first and second locking positions. At the same time, the structure is simple and reliable, and the operation is highly convenient.
[0029] In this embodiment, the rotating rod 203 can float up and down relative to the limiting cylinder 201a. A spring seat 203a is fixedly provided on the upper part of the rotating rod 203, and a compression spring 206 is provided in the limiting cylinder 201a. One end of the compression spring 206 abuts against the spring seat 203a, and the other end of the compression spring 206 abuts against the bottom of the limiting cylinder 201a. Specifically, the spring seat 203a is welded and fixed to the upper part of the rotating rod 203. It can be understood that the limiting cylinder 201a has a hollow inner cavity, the compression spring 206 is disposed in the hollow inner cavity, and the spring seat 203a can follow the rotating rod 203. The rotating rod 203 slides within the limiting cylinder 201a. By setting the rotating rod 203 to be able to float up and down, the risk of jamming of the rotating rod 203, clamping block 202, and position locking plate 201b can be reduced. At the same time, the floating gap (the vertical floating distance of the rotating rod 203 is preferably set between 1.0-3.0mm) is conducive to compensating for the thickness error of the flange portion 401 of the flange valve body 4, so that the clamping block 202 can be smoothly rotated to the bottom surface of the flange portion 401. The compression spring 206 can make the clamping block 202 fit against the bottom surface of the flange portion 401, improving the hoisting stability.
[0030] In this embodiment, the substrate 1 is a circular plate, and the edge of the substrate 1 extends radially outward to form a support ear 101. The limiting cylinder 201a is fixed on the support ear 101. Specifically, the limiting cylinder 201a is welded and fixed on the support ear 101. The support ear 101 facilitates the installation of the limiting cylinder 201a, helps to ensure the overall lightweight design of the substrate 1, and reduces the amount of material used in the substrate 1. At the same time, the circular plate structure can ensure a large-area fit between the substrate 1 and the top surface of the flange 401, resulting in good structural reliability and durability.
[0031] In this embodiment, the clamping mechanism 2 is evenly distributed in three groups along the circumference of the substrate 1. The three groups provide good clamping stability for the flange valve body 4.
[0032] In this embodiment, the substrate 1 is a circular plate, and an annular anti-scratching plate 102 is fixedly provided at the bottom of the substrate; specifically, the annular anti-scratching plate 102 is made of nylon. By providing the annular anti-scratching plate 102, scratches between the substrate 1 and the flange 401 contact surface can be avoided, thereby further ensuring production quality, and the circular plate has good structural strength. More specifically, an annular groove is provided on the bottom surface of the substrate 1, and the annular anti-scratching plate 102 is fixed in the annular groove by adhesive bonding, which effectively ensures the installation stability of the annular anti-scratching plate 102 and the durability of the overall structure.
[0033] In this embodiment, the substrate 1 is an aluminum plate, and two weight-reduction holes 103 are provided on the substrate 1. By using an aluminum plate and providing weight-reduction holes 103, the overall structure is effectively made lightweight, which helps to further reduce labor intensity.
[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
