Detailed Implementation This application provides a maintenance device for a vertical slide gate valve, which includes at least a moving carrier 1, a guiding mechanism 3, and a translation mechanism 2. The guiding mechanism 3 is located on one side of the slide gate valve and is used to guide the moving carrier 1 to move to a predetermined position close to the slide gate valve. The translation mechanism 2 is movably located on the moving carrier 1 and is used to support and fix the slide gate valve cover, and can drive the slide gate valve cover to open or close.

[0015] One embodiment of this application provides a maintenance device for a vertical slide gate valve, comprising a mobile carrier, a guiding mechanism, and a translation mechanism. The mobile carrier can move within the equipment site, and the guiding mechanism guides the mobile carrier to a predetermined position close to the slide gate valve. The translation mechanism on the mobile carrier carries and fixes the slide gate valve cover, and the translation mechanism drives the slide gate valve cover to translate, thereby opening or closing the slide gate valve cover. This application can avoid the bump damage caused by manual lifting of the valve core and solve the problem of difficulty in manually positioning the valve core when using a crane, thus greatly improving the maintenance efficiency of the slide gate valve core.

[0016] Specifically, this application provides a translation mechanism for the maintenance of a vertical slide gate valve. The translation mechanism 2 includes a slide rail 21 mounted on a mobile carrier 1, and a translation fixture 23 slidably mounted on the slide rail 21 via a slider 22. The translation fixture 23 is used to support and fix the slide gate valve cover, and can drive the slide gate valve cover to slide along the slide rail 21. This vertical slide gate valve maintenance mechanism utilizes the large-scale movement of the mobile carrier within the equipment site and uses a linear slide rail to achieve manual translation of the valve body fixture, thereby opening and closing the valve cover. This enables the installation and maintenance of the entire slide gate valve body, avoiding damage caused by manual lifting of the valve core, and solving the problem of difficulty in manually positioning the valve core during crane lifting. This significantly improves the maintenance efficiency of the slide gate valve core.

[0017] Furthermore, the mobile carrier 1 is provided with at least two parallel slide rails 21; each slide rail 21 is provided with at least two sliders 22 spaced apart. This design can improve movement stability, increase positioning accuracy, and facilitate operation.

[0018] In a preferred embodiment of this application, a height adjustment structure 24 for adjusting the height of the translation tooling 23 is provided between the translation tooling 23 and the slider 22. Specifically, the height adjustment structure 24 includes an adjustment seat 241, a connecting seat 243, a connecting member 244, and an adjustment screw 245; the adjustment seat 241 is disposed on the slider 22 and has a vertical waist-shaped groove 242 thereon; the connecting seat 243 is disposed on the translation tooling 23 and is located on one side of the adjustment seat 241; the connecting member 244 passes through the waist-shaped groove 242 and is connected to the connecting seat 243; the adjustment screw 245 is threadedly connected to the connecting seat 243 and its end abuts against the adjustment seat 241. The connector can be a screw or other fastener, which connects the adjusting seat and the connecting seat, forming a connection between the translation tooling and the slider. Due to the presence of the slot, there is a vertical adjustment margin between the two. By adjusting the adjusting screw, the height difference between the adjusting seat and the connecting seat can be adjusted, thereby adjusting the overall height of the translation tooling. This design allows for fine-tuning, increases the applicability of the product, improves the accuracy of valve cover installation and positioning, and improves the maintenance efficiency of the slide valve core.

[0019] More preferably, the adjusting seat 241 has at least two parallel waist-shaped grooves 242, and each of the at least two waist-shaped grooves 242 is connected to the connecting seat 243 via a connecting member 244. This design improves installation stability. Specifically, this application has a height adjustment structure installed between each slider and translation tooling, which can adjust and correct the overall height and the height in each direction in a timely manner, improving maintenance stability.

[0020] As a further preferred embodiment of this application, a positioning structure 25 for locking the position of the translation tool 23 is provided between the translation tool 23 and the moving carrier 1. Specifically, the positioning structure 25 includes a locking hole 251 on the moving carrier 1, a positioning hole 252 on the translation tool 23, and a positioning pin 253. When the positioning hole 252 on the translation tool 23 slides to the locking hole 251 on the moving carrier 1, the positioning pin 253 passes through the locking hole 251 and the positioning hole 252 to restrict the movement of the translation tool 23 relative to the moving carrier 1. This design allows the translation tool to be fixed in time after the valve cover of the slide gate valve is opened, facilitating maintenance and inspection and avoiding damage caused by manual lifting of the valve core.

[0021] Specifically, this application provides a guiding mechanism for the maintenance of a vertical slide gate valve. The guiding mechanism 3 includes a guide wheel assembly 30 fixedly disposed on one side of the slide gate valve. When the moving carrier 1 moves to contact the guide wheel assembly 30, the guide wheel assembly 30 limits the movement of the moving carrier 1, thereby guiding the moving carrier 1 to a predetermined position close to the slide gate valve. This patent is used for the maintenance of vertical slide gate valves. By utilizing the precise guidance of the guide wheel assembly, the moving carrier is moved to the predetermined maintenance position, facilitating subsequent installation and maintenance of the slide gate valve body. This application can avoid the bump damage caused by manual lifting of the valve core and solve the problem of difficulty in manually positioning the valve core during crane lifting, thus greatly improving the maintenance efficiency of the slide gate valve core.

[0022] Furthermore, there are two sets of guide wheel assemblies 30, which are arranged opposite to each other, forming a guide channel 34 that allows the mobile vehicle 1 to pass through. This design can guide the movement direction of the mobile vehicle, accurately enter the positioning and maintenance area, increase positioning accuracy, and facilitate subsequent maintenance operations of the slide gate valve core.

[0023] More preferably, the mobile carrier 1 is provided with a guide plate 35 for contacting the guide wheel assembly 30. The guide plate 35 cooperates with the guide wheel assembly 30 to limit the movement direction of the mobile carrier 1. Specifically, two guide plates 35 are provided on opposite sides of the mobile carrier 1. When the mobile carrier 1 enters the guide channel 34, the two guide plates 35 can cooperate with the two sets of guide wheel assemblies 30 respectively. This design improves the stability of guidance. By using the precise guidance of the guide wheel assembly and the guide plate, the mobile carrier is pre-positioned and locked onto the base frame of the coating equipment.

[0024] As a further preferred embodiment of this application, the mobile carrier 1 has forward-protruding guide portions 11 on both sides of its front end. The distance between the front ends of the two guide portions 11 is smaller than the distance between their rear ends, which is used to guide the mobile carrier 1 into the guide channel 34. This design facilitates the entry of the mobile carrier into the guide channel and greatly improves the maintenance efficiency of the slide gate valve core.

[0025] Furthermore, the guide wheel assembly 30 includes a fixing frame 31 for fixing, a guide wheel frame 32 disposed on the fixing frame 31, and a plurality of guide wheel members 33 rotatably disposed on the guide wheel frame 32, the guide wheel members 33 being in contact with the moving carrier 1. Specifically, the guide wheel frame 32 is provided with a guide wheel groove 320 extending in a horizontal direction, and a plurality of guide wheel members 33 are rotatably disposed in sequence within the guide wheel groove 320, with the rims of the plurality of guide wheel members 33 positioned outside the guide wheel groove 320 to contact the moving carrier 1. The moving carrier is moved to a predetermined position by the cooperation of the guide wheel members and the guide plate. In use, the guide wheel fixing frame needs to be fixed to the base frame of the coating equipment, and then the guide wheel assembly is installed on the fixing frame.

[0026] As a further preferred embodiment of this application, a spacing adjustment structure 36 for adjusting the distance between the fixed frame 31 and the guide wheel frame 32 is provided. Specifically, the spacing adjustment structure 36 includes a connecting screw 361 that passes through the fixed frame 31 and is threadedly connected to the guide wheel frame 32, and a pressing screw 362 that is threadedly connected to the fixed frame 31 and whose end presses against the guide wheel frame 32. This design allows for fine-tuning of the distance to a suitable range, enabling corresponding adjustments to the guide channel width and increasing product applicability.

[0027] Furthermore, the translation fixture 23 is constructed from square steel to form a square frame. The top and / or sides of the translation fixture 23 are provided with mounting seats 26 for supporting and fixing the slide gate valve cover. The translation fixture is mainly made of square tubing welded to steel plates. Two positions on the slide gate valve cover are fixed to the mounting seats with screws, and then the entire translation fixture is fixed to the linear slider with screws via connecting seats.

[0028] Furthermore, the mobile carrier 1 is equipped with a fixing component 12 for securing itself after entering the predetermined position, and is fitted with swivel casters 13 at the bottom. The mobile carrier is constructed entirely of square tubing welded to steel plates, with swivel casters at the bottom for overall movement of the trolley. Guide plates are welded to both sides for pre-positioning during valve cover installation. After the mobile carrier is positioned with screws, the fixing component is fixed to the base frame of the coating equipment to prevent the trolley from shifting during maintenance of the slide gate valve body. A linear guide rail is installed at the top for opening and closing the valve cover, thereby maintaining the slide gate valve core.

[0029] The working principle of this application is as follows: The mechanism uses casters to drive a mobile carrier to flexibly move to the working position in the equipment area. Then, using the precise guidance of the guide wheel assembly and guide plate, the fixing components firmly lock the tool trolley onto the base frame of the coating equipment. Next, the translation fixture is positioned on the slide gate valve cover and secured with screws. Subsequently, the valve body is manually moved back and forth via a linear slide rail, opening and closing the valve cover, thus completing the installation and maintenance of the entire slide gate valve body.

[0030] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
