Description

TECHNICAL FIELD

[0001] The present application relates to the field of disassembling tools, in particular to a high-adaptability diaphragm valve auxiliary disassembling equipment and disassembling method. BACKGROUND

[0002] The diaphragm valve is a special form of shut-off valve, and the core design thereof isolates the inner cavity of the valve body from the driving part through a flexible diaphragm to achieve sealing and corrosion prevention. The valve body and the valve cover are usually connected by bolts and nuts. When the diaphragm valve is disassembled, a wrench is needed to disassemble the nuts. When the nuts on the valve body are rusted or damaged, it is difficult for the ordinary wrench to disassemble the bolts.

[0003] Therefore, the Chinese patent application with the publication number CN118990400A discloses a self-adaptive force control wrench and a method for disassembling damaged bolts and nuts by using the wrench. The auxiliary plate is welded on the damaged nut, and then through the cooperative action of the movable rod (first clamping part) and the adjustable ring-shaped clamping block (second clamping part), the round head of the damaged bolt or the square head of the nut can be strongly clamped, and stronger clamping force can be provided, thereby achieving efficient disassembly.

Moreover, for the severely damaged nuts, the auxiliary plate needs to be welded on the nut, which is relatively cumbersome. Furthermore, since the nuts usually have a rust layer, the welding quality will be seriously affected during the welding process.

DETAILED DESCRIPTION

[0036] In order to further understand the features, technical means and specific purposes and functions achieved by the present application, the present application will be described in further detail below in conjunction with the drawings and specific embodiments.

[0037] REFERENCE Figures 1-4 The application discloses a high-adaptability diaphragm valve auxiliary dismounting equipment, which comprises a rack 1, wherein the rack 1 is provided with an axis extending in a vertical direction, and the rack 1 is provided with at least three adjusting rods 11 distributed in a circular array along the axis in a direction perpendicular to the axis; the adjusting rod 11 is provided with a hinged seat 12 at one end close to the axis, the hinged seat 12 is provided with a guide rod 121 in sliding cooperation with the adjusting rod 11, the hinged seat 12 is hinged with a clamping part 122 for clamping a bolt, and the hinged seat 12 is provided with a first elastic member 123 connected with the adjusting rod 11, wherein the first elastic member 123 is used for driving the guide rod 121 to slide when being stretched and contracted; and the rack 1 is provided with an adjusting mechanism 2 used for controlling the adjusting rod 11 to move in a direction perpendicular to the axis of the rack 1.

[0038] The application realizes the functions of adapting to the size of the bolt and disassembling by the rack 1, the adjusting rod 11, the hinged seat 12 and the adjusting mechanism 2, and the self-adapting and close-fitting effect according to the damage condition of the bolt is achieved by the cooperation of the adjusting rod 11 and the hinged seat 12. In the disassembling process of the diaphragm valve, a large number of bolts are involved in the disassembling of the valve cover. The bolt has a plurality of abutting surfaces, and the clamping portion 122 has a clamping surface for abutting with the abutting surface. By utilizing the telescopic and rotatable characteristics of the guide rod 121 and the hinged seat 12, the clamping portion 122 can be fitted to the abutting surface of different angles, so that the disassembling can be carried out even if the bolt is locally damaged, thereby improving the disassembling portability of the diaphragm valve. The problem that the traditional adjustable wrench cannot accurately fit the locally deformed or damaged bolt is solved. The side of the clamping portion 122 away from the hinged seat 12 is provided with a rubber pad, and after the rubber pad abuts against the bolt, the friction between the clamping portion 122 and the abutting surface is improved by the rubber pad, thereby improving the disassembling stability. In the working state, the operator first moves the clamping portion 122 of the rack 1 to the bolt to be disassembled, and makes the axis of the rack 1 close to the axis of the bolt. Then the adjusting mechanism 2 is used to control the plurality of adjusting rods 11 to move towards the axis of the rack 1 until the plurality of clamping portions 122 abut against the bolt. Then the operator rotates the rack 1, drives the adjusting rod 11 and the clamping portion 122 to rotate by the rack 1, and then pushes the bolt to rotate, thereby disassembling the bolt.

[0039] Referring to Figures 5-7 The rack 1 is provided with a mounting seat 21; each adjusting rod 11 is provided with two transmission rods 22, and adjacent adjusting rods 11 are transmissionally connected through the transmission rods 22; the mounting seat 21 is provided with a linear driver 211 for driving the transmission rod 22 to move, and when one of the adjusting rods 11 moves, the remaining adjusting rods 11 are driven to move through the transmission rod 22.

[0040] The mounting seat 21, the linear driver 211 and the transmission rod 22 realize the function of driving the plurality of adjusting rods 11 to move, the linear driver 211 can drive the plurality of adjusting rods 11 to synchronously extend and retract through the connection of the transmission rod 22, thereby quickly adjusting the positions of the plurality of clamping portions 122, and the bolt can be accurately positioned on the axis of the rack 1, thereby improving the stability of the torque transmission. The linear driver 211 is preferably a micro electric push rod, and the rack 1 is provided with a controller for human-computer interaction, and the linear driver 211 is electrically connected with the controller. In the working state, the operator first moves the rack 1 to the bolt to be disassembled, and then sends a signal to the linear driver 211 through the controller, and the linear driver 211 drives the transmission rod 22 to move after receiving the signal, and the transmission rod 22 drives the adjusting rod 11 to move, and adjacent adjusting rods 11 are transmissionally connected through the transmission rod 22, so that the plurality of adjusting rods 11 can be synchronously driven to move along the radial direction of the axis at the same time, thereby performing the subsequent disassembling work.

[0041] Referring toFigures 5-7 The first sliding groove 212 is vertically arranged on the mounting base 21 and extends along the axis direction of the rack 1; the extension rod 111 is arranged on the adjusting rod 11, and the second sliding groove 1111 is arranged on the extension rod 111 and extends along a direction perpendicular to the extension direction of the adjusting rod 11; the convex shaft 221 and the sliding block 222 are arranged at the two ends of the transmission rod 22, the convex shaft 221 is in sliding fit with the first sliding groove 212, and the sliding block 222 is in sliding fit with the second sliding groove 1111.

[0042] The first sliding groove 212, the second sliding groove 1111, the convex shaft 221 and the sliding block 222 are used to guide the movement of the transmission rod 22, so that the multiple adjusting rods 11 are synchronously moved by the transmission rod 22. The sliding block 222 is a square sliding block 222, the end of the transmission rod 22, where the convex shaft 221 is arranged, is provided with an upward extending flange, and the driving end of the linear driver 211 is connected with the flange of the transmission rod 22. The extension rod 111 is fixedly connected with the adjusting rod 11. When the linear driver 211 drives the movement of the transmission rod 22, the movement direction of the transmission rod 22 is guided by the cooperation between the convex shaft 221 on the transmission rod 22 and the first sliding groove 212, and at the same time, the transmission rod 22 pushes the extension rod 111, and then pushes the adjusting rod 11 to move, and the sliding block 222 of the transmission rod 22 slides along the second sliding groove 1111. The transmission rod 22 is guided by the first sliding groove 212 and the second sliding groove 1111, so that the transmission rod 22 can stably push the adjusting rod 11 to move, and two transmission rods 22 are slidably connected on each extension rod 111, and the adjacent two transmission rods 22 are driven to move by the same linear driver 211, so that the transmission system drives the multiple adjusting rods 11 to synchronously move.

[0043] Referring to Figure 3 and Figure 8 The clamping part 122 is provided with a locking mechanism 3 for limiting the rotation of the clamping part 122, the locking mechanism 3 comprises a tension spring 31, a lock column 32 and a lifting assembly 33 for controlling the lifting of the lock column 32; the two ends of the tension spring 31 are respectively hinged to the clamping part 122 and the hinged seat 12; the lock column 32 is arranged on the clamping part 122 and can be lifted, and the hinged seat 12 is provided with a lock groove 124 matched with the lock column 32, and when the lock column 32 is matched with the lock groove 124, the rotation of the clamping part 122 is limited.

[0044] The present application realizes the function of the fixed clamping part 122 through the tension spring 31, the lock post 32 and the lifting assembly 33. Four tension springs 31 are arranged on each clamping part 122, and the four tension springs 31 are distributed on both sides of the clamping part 122 in pairs. In the initial state, the clamping part 122 is in the balanced state under the elastic force of the tension spring 31, and the normal line of the clamping surface of the clamping part 122 is parallel to the extension direction of the adjusting rod 11. In the working state, the operator first controls the synchronous movement of the plurality of adjusting rods 11 towards the direction close to the axis of the rack 1 through the adjusting mechanism 2, until the clamping block abuts against the abutting surface. In this process, if there is an included angle between the clamping surface of the clamping block and the abutting surface, the clamping block will tilt under the pressure, the clamping part 122 rotates relative to the hinged seat 12, until the clamping surface of the clamping part 122 abuts against the abutting surface.

[0045] With reference to Figure 8 and Figure 9 The lifting assembly 33 comprises an adjusting block 331 and a connecting rod 332; the adjusting block 331 is hinged on the clamping part 122; the two ends of the connecting rod 332 are respectively hinged with the lock post 32 and the adjusting block 331; the clamping part 122 is provided with a locking assembly 34 for fixing the adjusting block 331, when the lock post 32 is inserted and matched with the lock slot 124, the locking assembly 34 limits the movement of the adjusting block 331.

[0046] The application achieves the function of controlling the plug-in cooperation of the lock post 32 and the lock slot 124 through the adjusting block 331, the connecting rod 332 and the locking assembly 34, and limits the movement of the adjusting block 331 through the locking assembly 34, so as to maintain the state of the lock post 32. The lock post 32 is provided with a plurality of convex strips made of rubber, and the lock slot 124 is provided with grooves matched with the convex strips. The extension direction of the convex strips is parallel to the axis of the lock post 32, and the plurality of convex strips are distributed in a circular array along the axis of the lock post 32. The convex strips and the grooves are one-to-one corresponding, and the number of the convex strips and the grooves is sufficient, so that the adjusting precision is sufficient, and after adjusting the angle of the clamping part 122, the clamping part 122 can be locked smoothly. The adjusting block 331 is connected with a knob 333 for the operator to grasp, and the clamping part 122 is provided with a cylindrical through hole for guiding the lifting of the lock post 32. The operator controls the movement of the plurality of adjusting rods 11 through the adjusting mechanism 2 until the clamping surfaces of the plurality of clamping parts 122 respectively abut against the plurality of abutting surfaces of the nut. However, some nuts may have serious local damage, which causes the clamping surface of part of the clamping parts 122 to be unable to abut against the corresponding abutting surface no matter how the angle is adjusted. When disassembling, at least three clamping surfaces need to be closely attached to the corresponding abutting surfaces to provide sufficient torque, and through the design of the lock post 32 and the lock slot 124, the adjusting flexibility of the clamping part 122 is further improved, thereby improving the applicability of the disassembling equipment. At this time, the operator grasps and presses the knob 333 downward, the knob 333 drives the adjusting block 331 to rotate, the adjusting block 331 pushes the lock post 32 downward through the connecting rod 332, until the bottom end of the lock post 32 enters the lock slot 124 and is plug-in matched with the lock slot 124, and through the arrangement of the convex strips and the grooves, the lock post 32 can be relatively smoothly inserted into the lock slot 124. When the lock post 32 has a rotating tendency, the convex strips are deformed under stress, and then the cooperation of the convex strips and the grooves increases the friction force when the lock post 32 rotates, so as to limit the sliding of the lock post 32 and the movement of the adjusting block 331. When the clamping part 122 abuts against the surface of the damaged bolt, the rotating angle of the clamping part 122 can be adjusted by changing the relative position of the contact surface and the surface of the bolt, so that the clamping part 122 can be smoothly inserted into the lock slot 124 when abutting against the surface of the bolt. Figures 8-10 The locking assembly 34 comprises a support 341, a clamping block 342 and a second elastic member 343; the support 341 is installed on the clamping part 122; the clamping block 342 is slidingly installed on the support 341; and the two ends of the second elastic member 343 are respectively connected with the clamping block 342 and the support 341.

[0047] The application realizes the function of limiting the movement of the adjusting block 331 through the support 341, the clamping block 342 and the second elastic member 343, thereby achieving the effect of fixing the adjusting block 331 and the lock column 32. An arc surface is formed on the clamping block 342, and a containing groove for containing the clamping block 342 is formed on the support 341. When the operator presses the knob 333, the knob 333 drives the adjusting block 331 to rotate, and the adjusting block 331 pushes the lock column 32 to move downward through the connecting rod 332. When the adjusting block 331 contacts the arc surface of the clamping block 342, the clamping block 342 is extruded, and the second elastic member 343 is contracted under the pressure. The clamping block 342 is contracted into the containing groove. When the adjusting block 331 completely passes through the clamping block 342, the lock column 32 is inserted and matched with the lock groove 124. At the same time, the clamping block 342 is stretched out of the containing groove under the elastic force of the second elastic member 343, and the bottom surface of the clamping block 342 abuts against the top surface of the adjusting block 331. The movement of the adjusting block 331 is limited through the clamping block 342, thereby limiting the movement of the lock column 32. The rotation of the clamping part 122 is limited through the friction force between the groove wall of the lock groove 124 and the lock column 32, thereby maintaining the state of the clamping part 122.

[0048] With reference to Figure 1 , Figure 2 and Figure 11 : The mounting ring 4 is arranged on the frame 1, and the handle 41 for gripping is arranged on the mounting ring 4.

[0049] The mounting ring 4 and the handle 41 facilitate the rotation of the frame 1 and the adjusting rod 11 by the operator, thereby facilitating the disassembly and assembly of the bolt by the operator, and improving the disassembly and assembly portability of the diaphragm valve. When the nut is disassembled and assembled, the operator moves the equipment to the nut to be disassembled and assembled, and then controls the plurality of clamping parts 122 to cooperate with the nut through the adjusting mechanism 2. Then the operator holds the handle 41 and rotates the mounting ring 4, thereby driving the frame 1 and the adjusting rod 11 to rotate through the mounting ring 4, rotating the nut through the clamping part 122 at the end of the adjusting rod 11, and efficiently disassembling and assembling the nut.

[0050] With reference to Figure 1 and Figure 2 : The elastic telescopic rod 42 and the connecting block 43 are arranged on the frame 1; the elastic telescopic rod 42 comprises a main rod 421 and a secondary rod 422, the main rod 421 is connected with the frame 1 through the connecting block 43, and the secondary rod 422 is connected with the mounting ring 4; the mounting ring 4 is in sliding cooperation with the connecting block 43.

[0051] The elastic telescopic block and the connecting block 43 realize the function of guiding the installation ring 4. The main rod 421 has a closed cavity, and the closed cavity is filled with high-pressure gas, and the auxiliary rod 422 is provided with a piston for compressing high-pressure gas near one end of the main rod 421. The elastic telescopic rod 42 plays the role of a gas spring. The main rod 421 and the auxiliary rod 422 are in a circular arc shape, and the connecting block 43 is in a cylindrical shape. The connecting block 43 is provided with at least three, and a plurality of connecting blocks 43 are distributed in a circular array along the axis of the installation ring 4. The installation ring 4 is guided to rotate through the sliding fit of the plurality of connecting blocks 43 and the installation ring 4. The installation ring 4 is provided with a push block 44 for connecting with the auxiliary rod 422. After the clamping part 122 cooperates with the bolt, the operator rotates the handle 41 to drive the installation ring 4 to rotate. At this time, the installation ring 4 drives the auxiliary rod 422 to shrink, and then the pressure is transmitted to the rack 1 through the elastic telescopic rod 42 to drive the rack 1 to rotate. During the rotation process, the operator can judge the rotation torque by the shrinkage of the elastic telescopic rod 42, so as to avoid that the bolt is damaged due to bearing too large torque.

[0052] With reference to Figure 1 The rack 1 is provided with a support 5, and the support 5 is provided with a vibration motor 51.

[0053] The support 5 and the vibration motor 51 realize the function of providing high-frequency short-pulse vibration, and then the vibration achieves the effect of destroying the rust layer structure and eliminating the mechanical engagement stress between threads, so as to improve the disassembly efficiency by loosening the bonding surface. At the same time, the vibration can eliminate the engagement stress, so as to reduce the torque required for rotating the bolt, and further avoid the damage of the bolt due to too high torque.

[0054] With reference to Figures 1-4 A high-adaptability diaphragm valve auxiliary disassembly method comprises the following steps:

[0055] S1, moving the equipment to the bolt to be disassembled, and placing the bolt between the plurality of clamping parts 122;

[0056] S2, controlling the adjusting rod 11 to move towards the bolt through the adjusting mechanism 2, until at least three clamping parts 122 abut against the bolt;

[0057] S3, rotating the rack 1, the rack 1 drives the adjusting rod 11 and the clamping part 122 to rotate, the clamping part 122 drives the bolt to rotate, and the disassembly action is performed.

[0058] The above embodiments only express one or several embodiments of the present application, the description is more specific and detailed, but it cannot be understood as the limitation of the scope of the present application. It should be noted that for ordinary skilled in the art, without departing from the concept of the present application, several modifications and improvements can be made, which belong to the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
