Abstract
Description
Technical Field
[0001] This invention relates to the technical field of intelligent assembly of butterfly valves, and more specifically, to a device for semi-automatic assembly and debugging of large-size butterfly valves. Background Technology
[0002] Large-diameter butterfly valves, with nominal diameters ranging from DN500 to DN1200 and weights from 280 to 1620 kg, have the valve body, butterfly plate, upper and lower valve stems, and worm gear assembly accounting for most of their weight. This makes them difficult to install and debug. Currently, many valve manufacturers lack the equipment to assist in the assembly and debugging of large-diameter butterfly valves when mass-producing them. This makes installation difficult for workers, which can easily lead to worker injuries. Mass production also results in long production cycles and low production efficiency.
[0003] Existing technology discloses a biaxial positioner for assembling main valve components, including a tilting mechanism, a rotating mechanism mounted on the tilting mechanism, and a rotating tooling fixture mounted on the rotating mechanism. The rotation axis of the rotating mechanism is perpendicular to the rotation axis of the tooling fixture. The tilting mechanism and the rotating mechanism rotate together, and the arrangement of their perpendicular rotation axes facilitates the adjustment of various end faces of the main valve component. This solution achieves the assembly effect of the main valve in different positions using a positioner, exhibiting a high degree of intelligence, reducing labor intensity, and improving production efficiency.
[0004] However, in large-diameter butterfly valves, aligning the butterfly plate hole with the valve body hole is difficult, requiring a considerable amount of time. The butterfly plate and valve body are connected by two valve stems, and the butterfly plate itself weighs several hundred kilograms. Aligning it with the valve body through-hole requires a lengthy adjustment period before the valve stem can be inserted, resulting in low production efficiency. Furthermore, after assembly, large-diameter butterfly valves require no-load opening and closing verification and adjustment. However, most equipment lacks a testing function, leading to direct pressure testing after assembly and a low yield rate. This can also result in undetected problems until they are discovered at the customer's site, causing delays in the project. Therefore, existing technologies present technical challenges in the installation and commissioning of large-diameter butterfly valves. Summary of the Invention
[0005] The purpose of this invention is to overcome the shortcomings of existing technologies in terms of the difficulty of installing and debugging large-diameter butterfly valves, and to provide a semi-automatic device for assembling and debugging large-specification butterfly valves.
[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:
[0007] A semi-automatic assembly and debugging device for large-size butterfly valves includes a turntable mechanism for fixing the butterfly plate, a lifting and flipping mechanism for fitting the valve body onto the outer ring of the butterfly plate and capable of lifting, lowering, and flipping the valve body, a first propulsion mechanism and a second propulsion mechanism respectively disposed on both sides of the lifting and flipping mechanism for fixing the valve stem, and a debugging transmission mechanism disposed above the lifting and flipping mechanism for debugging the butterfly valve. The first propulsion mechanism and the second propulsion mechanism can move relative to the lifting and flipping mechanism to install the valve stem onto the valve body and the butterfly plate.
[0008] This invention discloses a semi-automatic assembly and debugging device for large-diameter butterfly valves. After the turntable mechanism fixes the butterfly plate, the valve body is fixed on the lifting and tilting mechanism and fitted onto the outer ring of the butterfly plate, ensuring that the butterfly plate and the through holes on both sides of the valve body are coaxially aligned. The valve stem is then fixed to the first and second propulsion mechanisms on both sides of the lifting and tilting mechanism. The first and second propulsion mechanisms are controlled to move from both sides towards the lifting and tilting mechanism, allowing the valve stem to insert into the through holes of the valve body and the butterfly plate, thus completing the assembly of the main valve. The lifting and tilting mechanism is then controlled to first raise and lower the valve body a certain distance before tilting it, bringing the debugging end of the butterfly valve close to the debugging transmission mechanism at the top of the lifting and tilting mechanism for debugging. This completes the automatic opening and closing debugging and verification of the butterfly valve. This invention utilizes the coordinated operation of multiple mechanisms to achieve automatic assembly and debugging of large-diameter butterfly valves, reducing manual operation and labor intensity, increasing product qualification rate, and shortening the product assembly and debugging cycle. It effectively solves the technical problem of difficult installation and debugging of large-diameter butterfly valves in the prior art.
[0009] Furthermore, the turntable mechanism includes a fixed base, a rotating disk rotatably mounted on top of the fixed base, and several support columns located on the upper edge of the rotating disk. A positioning seat for fixing the butterfly plate is provided on the top of the rotating disk. The support columns on the upper edge of the rotating disk allow for control of the rotating disk's rotation, facilitating manual adjustment of the butterfly plate's direction. The positioning seat is used to fix the butterfly plate, ensuring its stable fixation to the rotating disk.
[0010] Furthermore, the lifting and tilting mechanism includes a frame, a guide seat vertically slidably mounted on the frame, a first driving device mounted on the frame for driving the guide seat to slide, a tilting base plate rotatably connected to the guide seat for fixing the valve body, and a second driving device mounted on the frame for driving the tilting base plate to rotate. The tilting base plate has a mounting hole that allows the rotating disk to pass through. The first driving device controls the tilting base plate to descend, causing the rotating disk to pass through the mounting hole, and then the valve body is mounted on the tilting base plate, so that the valve body is fitted onto the outer ring of the butterfly valve. The second driving device controls the tilting base plate to rotate, which facilitates technicians to inspect the installation status on both sides of the valve body and promptly detect any problems with the butterfly valve installation.
[0011] Furthermore, the first driving device includes two sets of lead screws respectively vertically rotatably mounted on both sides of the frame, a main shaft rotatably mounted on the fixed base, and a drive motor mounted on the frame for driving the main shaft to rotate. The bottom of the lead screw and both ends of the main shaft are provided with helical gears that can mesh with each other. The guide seat is threadedly connected to the lead screw. Rotating the main shaft on the fixed base helps stabilize the rotation of the main shaft and can stably and synchronously drive the lead screws on both sides to rotate.
[0012] Furthermore, the first propulsion mechanism includes a first movable base, a movable base slidably disposed on the first movable base, a sixth driving device disposed on the movable base and used to drive the movable base to slide, a lift disposed on the movable base, and a V-block disposed on the lift and used to fix the valve stem. The lift can push the V-block to move vertically up and down, and the moving direction of the movable base is perpendicular to the rotation axis of the flip-up base plate. The valve stem is placed on the V-block and fixed, and the sixth driving device drives the movable base to slide on the first movable base to realize the automatic propulsion of the valve stem; the lift is used to adjust the height of the valve stem to realize the adjustment of the axial height of the valve stem.
[0013] Furthermore, the first propulsion mechanism is equipped with a radial drilling machine mechanism, which includes a drill column vertically mounted on the movable base, a rotating frame rotatably mounted on the drill column, a gearbox located at the end of the rotating frame, a drill bit movably mounted at the bottom of the gearbox, a seventh drive device located inside the gearbox for driving the drill bit to rotate, and a handwheel located in the gearbox for controlling the vertical movement of the drill bit. By manually operating the rotating frame to rotate relative to the drill column, the gearbox at the end of the rotating frame can be adjusted to be above the butterfly valve. The seventh drive device drives the drill bit to rotate, and the drilling operation is achieved by operating the handwheel to make the drill bit vertically downward.
[0014] Furthermore, the second propulsion mechanism includes a second movable base, a support seat slidably mounted on the second movable base, an eighth driving device mounted on the support seat for driving the support seat to slide, a telescopic frame vertically mounted on the support seat, a ninth driving device mounted on the support seat for driving the telescopic frame to extend and retract, a guardrail base plate mounted on top of the telescopic frame, and a V-block mounted on the guardrail base plate for fixing the valve stem. A fence is provided around the guardrail base plate, and the moving direction of the support seat is parallel to the moving direction of the movable base. The valve stem is placed and fixed on the V-block, and the eighth driving device drives the support seat to slide on the second movable base, achieving automatic propulsion of the valve stem. The ninth driving device drives the telescopic frame to extend and retract vertically to adjust the height of the valve stem, achieving axial height adjustment. The fence around the guardrail base plate facilitates the inspection and adjustment of the valve installation by personnel as the guardrail base plate rises and falls.
[0015] Furthermore, the telescopic frame includes several sets of vertically arranged cross units. Each cross unit includes two sets of load-bearing arms centrally rotatably connected. The ends of the two sets of load-bearing arms between the several sets of cross units are rotatably connected. The bottom end of one set of load-bearing arms in the lowest cross unit is rotatably connected to the support base, and the bottom end of the other set of load-bearing arms is slidably connected to the support base. The ninth driving device is a hydraulic cylinder. The body of the hydraulic cylinder is rotatably connected to the support base, and the push rod of the hydraulic cylinder is rotatably connected to any set of load-bearing arms in the second set of cross units from bottom to top. Because the body of the hydraulic cylinder is rotatably connected to the support base, and the push rod of the hydraulic cylinder is rotatably connected to any set of load-bearing arms in the second set of cross units from bottom to top, and the bottom end of one set of load-bearing arms in the lowest cross unit is rotatably connected to the support base, and the bottom end of the other set of load-bearing arms is slidably connected to the support base, the telescopic frame can be driven to extend or retract when the hydraulic cylinder extends or retracts its push rod, thus realizing the raising and lowering of the guardrail base plate.
[0016] Furthermore, the debugging transmission mechanism includes a debugging base mounted on the top of the frame, a front-to-back moving plate slidably mounted on the debugging base, a third driving device mounted on the debugging base for driving the front-to-back moving plate to slide, a left-to-right moving plate slidably mounted on the front-to-back moving plate, a fourth driving device mounted on the front-to-back moving plate for driving the left-to-right moving plate to slide, a synchronous wheel rotatably mounted on the left-to-right moving plate near the flipping base plate, and a fifth driving device mounted on the left-to-right moving plate for driving the synchronous wheel to rotate. The moving direction of the front-to-back moving plate is parallel to the rotation axis of the flipping base plate, and the moving direction of the left-to-right moving plate is perpendicular to the moving direction of the front-to-back moving plate. Since the moving direction of the front-to-back moving plate is parallel to the rotation axis of the flipping base plate, and the moving direction of the left-to-right moving plate is perpendicular to the moving direction of the front-to-back moving plate, the left-to-right moving plate and the front-to-back moving plate can cooperate to adjust the position of the synchronous wheel in the plane, install the synchronous belt between the synchronous wheel and the input end of the butterfly valve, and the fifth driving device serves as the power input source for the butterfly valve, realizing multiple opening and closing debugging of the butterfly valve.
[0017] Furthermore, it also includes an overhead crane mechanism, comprising several sets of columns arranged on both sides of the frame, front and rear guide rails respectively mounted on the two rows of columns, left and right guide rails slidably mounted on the guide rails on both sides, a crane slidably mounted on the left and right guide rails, and a tenth drive device mounted on the left and right guide rails for driving the crane to slide. The left and right guide rails are parallel to the rotation axis of the flipping base plate and perpendicular to the front and rear guide rails. Because the left and right guide rails are parallel to the rotation axis of the flipping base plate and perpendicular to the front and rear guide rails, the crane can move to any position above the frame to lift heavy objects. This not only allows for the hoisting of components above the frame to assist technicians in installing butterfly valves, but also allows for the hoisting of assembled finished products away from the frame, reducing the labor intensity of workers.
[0018] Compared with the prior art, the beneficial effects of the present invention are:

By utilizing the coordinated operation of a turntable mechanism, a lifting and tilting mechanism, a first propulsion mechanism, a second propulsion mechanism, and a debugging transmission mechanism, the device achieves automatic assembly and debugging of large-diameter butterfly valves, reduces manual operation and alleviates the labor intensity of workers, increases the product qualification rate, and shortens the product assembly and debugging cycle. It effectively solves the technical problem of difficulty in installing and debugging large-diameter butterfly valves in the prior art. Attached Figure Description

[0033] like Figures 1 to 4The image shows a first embodiment of a semi-automatic assembly and debugging device for large-size butterfly valves according to the present invention.
[0034] A semi-automatic assembly and debugging device for large-size butterfly valves includes a turntable mechanism 1 for fixing a butterfly plate a, a lifting and tilting mechanism 2 for fitting a valve body b onto the outer ring of the butterfly plate a and for lifting, tilting, and rotating the valve body b, a first pushing mechanism 3 and a second pushing mechanism 4 respectively located on both sides of the lifting and tilting mechanism 2 for fixing a valve stem c, and a debugging transmission mechanism 5 located above the lifting and tilting mechanism 2 for debugging the butterfly valve. The first pushing mechanism 3 and the second pushing mechanism 4 can move relative to the lifting and tilting mechanism 2 to install the valve stem c onto the valve body b and the butterfly plate a. The turntable mechanism 1 includes a fixed base 11, a rotating disk 12 rotatably mounted on top of the fixed base 11, and several support columns 13 located on the upper edge of the rotating disk 12. The top of the rotating disk 12 is provided with a positioning seat 14 for fixing the butterfly plate a. The lifting and tilting mechanism 2 includes a frame 21, a guide seat 22 vertically slidably mounted on the frame 21, a first driving device 23 mounted on the frame 21 for driving the guide seat 22 to slide, a tilting base plate 24 rotatably connected to the guide seat 22 for fixing the valve body b, and a second driving device 25 mounted on the frame 21 for driving the tilting base plate 24 to rotate. The tilting base plate 24 has a mounting hole 241 for accommodating the rotating disk 12. The first driving device 23 includes two sets of lead screws 231 vertically rotatably mounted on both sides of the frame 21, a main shaft 232 rotatably mounted on the fixed base 11, and a drive motor 233 mounted on the frame 21 for driving the main shaft 232 to rotate. The bottom of the lead screw 231 and the two ends of the main shaft 232 are provided with helical gears 234 that can mesh with each other. The guide seat 22 is threadedly connected to the lead screw 231.
[0035] In this embodiment, as Figures 1 to 2 As shown, after the turntable mechanism 1 fixes the butterfly plate a, the valve body b is fixed on the lifting and tilting mechanism 2 and the valve body b is fitted onto the outer ring of the butterfly plate a, so that the through holes on both sides of the butterfly plate a and the valve body b are coaxially aligned. Then, the valve stem c is fixed on the first pushing mechanism 3 and the second pushing mechanism 4 on both sides of the lifting and tilting mechanism 2. The first pushing mechanism 3 and the second pushing mechanism 4 are controlled to move from both sides and approach the lifting and tilting mechanism 2 so that the valve stem c is inserted into the through holes of the valve body b and the butterfly plate a, thus completing the assembly of the main valve. Then, the lifting and tilting mechanism 2 is controlled to first lift the valve body b a certain distance and then tilt the valve body b, so that the debugging end of the butterfly valve is close to the debugging transmission mechanism 5 at the top of the lifting and tilting mechanism 2 for debugging. This completes the automatic opening and closing debugging and verification of the butterfly valve. This invention utilizes the coordinated operation of multiple mechanisms to realize the automatic assembly and debugging of large-diameter butterfly valves, reduce manual operation and reduce the labor intensity of workers, increase the product qualification rate, and shorten the product assembly and debugging cycle. It effectively solves the technical problem of the difficulty in installing and debugging large-diameter butterfly valves in the prior art.
[0036] In this embodiment, as Figure 3 As shown, the support column 13 on the upper edge of the rotating disk 12 can support the butterfly plate a and allow the rotating disk 12 to be rotated manually, making it easy to manually adjust the direction of the butterfly plate a. The positioning seat 14 is used to fix the butterfly plate a, so that the butterfly plate a is stably fixed to the rotating disk 12.
[0037] In this embodiment, as Figure 4 As shown, the first driving device 23 controls the flip base plate 24 to descend so that the rotating disk 12 passes through the mounting hole 241, and then installs the valve body b on the flip base plate 24, so that the valve body b is fitted around the outer ring of the butterfly plate a. The second driving device 25 controls the flip base plate 24 to rotate, which makes it easier for technicians to check the installation status on both sides of the valve body b and to promptly detect any problems with the butterfly valve installation.
[0038] In this embodiment, as Figure 4 As shown, the spindle 232 is rotatably mounted on the fixed base 11. The fixed base 11 can help stabilize the rotation of the spindle 232 and stably and synchronously drive the lead screws 231 on both sides to rotate.

The telescopic frame 44 includes several sets of vertically arranged cross units 441. Each cross unit 441 includes two sets of load-bearing arms 442 that are centrally rotatably connected. The ends of the two sets of load-bearing arms 442 between the several sets of cross units 441 are rotatably connected.

A fence 47 is provided on the guardrail base plate 46 to facilitate the inspection and debugging of the valve by the staff as the guardrail base plate 46 rises and falls.
[0045] In this embodiment, as Figure 7 As shown, since the main body of the hydraulic cylinder is rotatably connected to the support base 42, the push rod of the hydraulic cylinder is rotatably connected to any one set of bearing arms 442 of the second set of cross units 441 from bottom to top, and the bottom end of one set of bearing arms 442 of the lowest cross unit 441 is rotatably connected to the support base 42, and the bottom end of the other set of bearing arms 442 is slidably connected to the support base 42, when the hydraulic cylinder extends or retracts the push rod, it can drive the telescopic frame 44 to extend and retract, thereby realizing the lifting and lowering of the guardrail base plate 46.
[0046] Example 3
[0047] like Figures 8 to 9 The image shows a third embodiment of a semi-automatic assembly and debugging device for large-size butterfly valves according to the present invention.
