Description

Technical Field

[0001] This utility model belongs to the field of regulating valve maintenance technology, and specifically relates to a positioning plate for regulating valve maintenance. Background Technology

[0002] During long-term use, control valves may experience wear, paint peeling, deformation, or inherent impurities that are difficult to clean. Regular maintenance is required, so a positioning plate is needed to position and fix the control valve.

[0003] While existing positioning plates for regulating valve maintenance can meet the basic requirement of positioning and fixing the regulating valve, they only allow for suspended fixing of the regulating valve and lack auxiliary support structures during the loading and unloading processes. This means that workers need to take additional measures to support the regulating valve during loading and unloading, which causes considerable inconvenience to users and affects the overall efficiency of regulating valve maintenance.

[0004] For example, the utility model patent with announcement number CN221037895U discloses an auxiliary device for the maintenance of a regulating valve. In the technical solution of this patent document, the worker needs to move the regulating valve to be maintained between the clamping structures before the regulating valve can be positioned and fixed. After the maintenance of the regulating valve is completed, the worker needs to support and fix the regulating valve again before the positioning and fixing structure can be released to fix the regulating valve and unload it. Therefore, it will cause great inconvenience to the worker's operation, waste the worker's time, and affect the overall efficiency of the maintenance of the regulating valve. Utility Model Content

[0005] In view of this, this utility model addresses the shortcomings of the prior art by providing a positioning plate for the maintenance of control valves. It not only meets the basic requirement of positioning and fixing control valves, but also automatically supports and fixes control valves without requiring manual support from workers. This allows for quick and convenient loading and unloading of control valves, thereby avoiding any impact on the overall efficiency of the maintenance of control valves.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a positioning plate for maintenance of a regulating valve, including a base, a support cylinder vertically arranged at the bottom corner of the base, a support rod inserted into the support cylinder, a connecting bolt for screwing and fixing the support rod on the support cylinder, a plurality of connecting holes adapted to the connecting bolts vertically opened on the support rod, linear slides running in the left and right directions respectively arranged on the left and right sides of the top of the base, vertical plates respectively arranged on the slides of the two linear slides, a connecting shaft horizontally penetrating and rotatably arranged on the two vertical plates, positioning clamps respectively arranged on the inner ends of the two connecting shafts, a drive module for rotating the connecting shaft is also arranged on one of the vertical plates, and a telescopic push rod is vertically arranged on the top of the base, and a placement plate is also arranged on the output shaft of the telescopic push rod.

[0007] As a further improvement of this utility model, a connecting frame is provided on all four support rods, and the connecting bolts are hand-tightened bolts.

[0008] As a further improvement of this utility model, the top of the base is also provided with a guide tube located at the side end of the telescopic push rod, and the bottom of the placement plate is also provided with a guide plate that is plugged into and connected to the guide tube.

[0009] As a further improvement of this utility model, the top of the placement plate is provided with a receiving groove along the front-back direction, and a bidirectional screw is rotatably arranged in the receiving groove along the front-back direction. An adjustment motor for rotating the bidirectional screw is provided at the rear end of the placement plate. The two ends of the bidirectional screw are respectively screwed with mounting blocks that are slidably connected to the receiving groove. Fixing plates for clamping and fixing the front and rear ends of the regulating valve are conveniently provided on the two mounting blocks.

[0010] As a further improvement of this utility model, a first anti-slip pad is provided on the inner end of the positioning plate, and a second anti-slip pad is provided on the inner end of the fixing clamp. The first and second anti-slip pads provided on the inner sides of the positioning clamp and the fixing clamp effectively prevent the clamped regulating valve from sliding during maintenance, further improving safety.

[0011] As a further improvement of this utility model, the drive module includes a drive motor horizontally arranged on the outer side wall of the vertical plate, a drive gear is provided on the output shaft of the drive motor, and a driven gear meshing with the drive gear is provided on the connecting shaft. The drive motor is a servo motor.

[0012] As a further improvement of this utility model, an anti-slip seat is also provided at the bottom of the support rod. The support rod with the anti-slip seat not only enhances the stability of the equipment when standing, but also facilitates handling and carrying, making it very suitable for rapid on-site deployment.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] Firstly, the height of the entire device can be easily adjusted through the combination of the support cylinder, support rod, multiple connecting holes, and connecting bolts to adapt to the needs of different working environments. At the same time, the hand-tightening bolt design makes operation simpler and faster.

[0015] Secondly, a connecting frame was added between the four support rods, which not only increased the overall stability of the structure, but also allowed users to easily adjust the height of the four support rods synchronously.

[0016] Thirdly, by combining a linear slide table and a drive module (including a servo motor, a drive gear, and a driven gear), the two ends of the control valve can be precisely clamped and fixed, ensuring the positional accuracy required during maintenance.

[0017] Fourth, the bidirectional screw design on the placement plate allows users to adjust the distance between the two fixed clamps according to actual needs, thereby better adapting to different types or sizes of regulating valves; while the combination of the guide sleeve and the guide plate ensures the stability of the placement plate when moving up and down.

Detailed Implementation

[0024] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0025] like Figure 1 As shown, a positioning plate for maintenance of a regulating valve includes a base 101. A support cylinder 102 is vertically arranged at the bottom corner of the base 101. A support rod 103 is inserted into the support cylinder 102. A connecting bolt 104 for screwing and fixing the support rod 103 is screwed onto the support cylinder 102. The support rod 103 has multiple vertically formed connecting holes 105 that are adapted to the connecting bolts 104. Straight lines running in the left and right directions are respectively arranged on the left and right sides of the top of the base 101. The slide table 106 has two linear slide tables 106, each with a vertical plate 107 on its slide base. A connecting shaft 108 is horizontally threaded through and rotatably mounted on each of the two vertical plates 107. Positioning clamps 109 are mounted on the inner ends of the two connecting shafts 108. A drive module for rotating the connecting shaft 108 is also mounted on one of the vertical plates 107. A telescopic push rod 110 is vertically mounted on the top of the base 101, and a placement plate 111 is mounted on the output shaft of the telescopic push rod 110. The connecting bolts 104 are hand-tightening bolts.

[0026] like Figure 1 , 3 As shown, the drive module includes a drive motor 401 horizontally disposed on the outer side wall of the vertical plate 107. A drive gear 402 is disposed on the output shaft of the drive motor 401, and a driven gear 403 meshing with the drive gear 402 is disposed on the connecting shaft 108. The drive motor 401 is a servo motor.

[0027] like Figure 1 As shown, the top of the base 101 is also provided with a guide tube 113 located at the side end of the telescopic push rod 110, and the bottom of the placement plate 111 is also provided with a guide plate 114 that is inserted and connected to the guide tube 113. Through the insertion and cooperation of the guide tube 113 and the guide plate 114, the placement plate 111 can move vertically smoothly, avoiding the telescopic push rod 110 from being easily deformed and damaged by non-vertical forces.

[0028] The user can first separate the connecting bolt 104 from the corresponding connecting hole 105 to release the fixation of the connection between the support cylinder 102 and the support rod 103. Then, the extension and retraction of the support rod 103 in the support leg can be adjusted so that the connecting bolt 104 corresponds to the new connecting hole 105, and the connecting bolt 104 can be reconnected to the new connecting hole 105. In this way, the support height of the base 101 can be adjusted, so that the overall height of the device can more conveniently meet the needs of the workers.

[0029] Afterwards, simply place the regulating valve that needs maintenance onto the placement plate 111. Then, the telescopic push rod 110 can be used to push the placement plate 111 and the regulating valve upwards, moving the regulating valve between the two positioning clamps 109. Then, the linear slides 106 on both sides can be used to drive the two positioning clamps 109 closer together, clamping and fixing the left and right ends of the regulating valve. Then, the telescopic push rod 110 can be used to move the placement plate 111 downwards, and the regulating valve can then be maintained. Furthermore, the drive motor 401 can be started, and the regulating valve can be rotated and adjusted through the drive gear 402 and the driven gear 403, in cooperation with the connecting shafts 108 on both sides and the positioning clamps 109, thus more fully meeting the needs of regulating valve maintenance.

[0030] After the control valve is inspected, the placement plate 111 is moved back below the control valve by the telescopic push rod 110. Then, the positioning clamps 109 on both sides can be moved away from each other by the linear slides 106 on both sides, releasing the clamp on the control valve. The control valve can then be removed from the placement plate 111. Therefore, the technical solution of this application allows workers to quickly and conveniently load and unload control valves, thus better meeting the needs of workers.

[0031] According to another embodiment of the present invention, such as Figure 4 As shown, a connecting frame 112 is provided on all four support rods 103. The connection frame 112 on all four support rods 103 increases the stability of the overall structure and also allows workers to easily adjust the height of the four support rods 103 synchronously.

[0032] According to another embodiment of the present invention, such as Figure 2 As shown, the top of the placement plate 111 is provided with a receiving groove 201 along the front-back direction. A bidirectional screw 202 is rotatably arranged in the receiving groove 201 along the front-back direction. An adjusting motor 203 for rotating the bidirectional screw 202 is provided at the rear end of the placement plate 111. The two ends of the bidirectional screw 202 are respectively screwed with mounting blocks 204 that are slidably connected to the receiving groove 201. Fixing clamps 205 for clamping and fixing the front and rear ends of the regulating valve are conveniently provided on the two mounting blocks 204.

[0033] After the regulating valve is placed on the placement plate 111, the bidirectional screw 202 can be driven to rotate by the adjusting motor 203, so that the two fixed clamping plates 205 can move relative to each other, thereby clamping or releasing the regulating valve. This effectively prevents the regulating valve from easily shifting during the vertical movement of the placement plate 111, and makes it convenient to release the fixing of the regulating valve.

[0034] According to another embodiment of the present invention, such as Figure 1 , 2 As shown, a first anti-slip pad 301 is provided on the inner end of the positioning plate, and a second anti-slip pad 302 is provided on the inner end of the fixing clamp 205. The first anti-slip pad 301 and the second anti-slip pad 302 provided on the inner sides of the positioning clamp 109 and the fixing clamp 205 effectively prevent the clamped regulating valve from sliding during maintenance, further improving safety.

[0035] According to another embodiment of the present invention, such as Figure 4 As shown, an anti-slip seat 115 is also provided at the bottom of the support rod 103. The anti-slip seat 115 can enhance the stability of the equipment when it is standing and prevent the device from easily shifting during operation.

[0036] The above are preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
