Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, specifically to a field welding repair device for diaphragm accumulators. Background Technology

[0002] Diaphragm accumulators isolate high-pressure gas from hydraulic oil through an elastic diaphragm, and store and release energy by utilizing the compressibility of gas, thereby achieving pressure compensation, buffering and energy recovery in hydraulic systems. They consist of a diaphragm, a housing and an interface.

[0003] A search revealed a utility model patent with Chinese patent publication number CN222596419U, which discloses a diaphragm-type accumulator, relating to the field of accumulators. The accumulator includes a container body, an air intake channel at the top of the container body, and a protective nut threaded onto the outer ring of the top of the air intake channel. An installation sleeve is threaded onto the inside of the air intake channel, and a threaded block is threaded onto the inside of the installation sleeve. The threaded block has a notch inside, and a short rod is movably installed inside the notch. A sealing block is fixedly connected to the lower end of the short rod.

[0004] As mentioned above, the casing of the accumulator needs to withstand a high-pressure environment, and it is inevitable that it will be damaged as the usage time increases. The accumulator is large in size and heavy in weight, and the transportation and downtime costs are high. Therefore, the cost of returning to the factory for repair is high. Therefore, a field welding repair device for diaphragm accumulator is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a field welding repair device for diaphragm accumulators to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a field welding repair device for a diaphragm accumulator, comprising a workbench, welding equipment fixedly installed on the top outer wall of the workbench, the welding equipment including a welding machine, a welding torch and a grounding clamp, a positioning assembly installed on the top of the workbench, the positioning assembly including an electric telescopic rod fixedly installed on the top outer wall of the workbench, a horizontally set limiting frame fixedly connected to the output end of the electric telescopic rod, a sliding groove opened on both sides of the top outer wall of the workbench, a movable frame slidably inserted into each of the two sliding grooves, a vertically set lead screw rotatably connected inside each of the two movable frames, a horizontally set support cover threaded onto the outside of each of the two lead screws, and a V-shaped limiting groove opened on the bottom outer wall of the support cover, two vertically set guide rods fixedly connected inside each of the two movable frames, and the support cover slidably fitted onto the outside of the two guide rods in the corresponding movable frames.

[0007] As a further preferred embodiment of this technical solution, a horizontally arranged lead screw is rotatably connected inside the limiting frame. An abutment plate is threaded onto the outside of the lead screw, and the lower half of the abutment plate is in contact with the inner wall of the limiting frame. A stabilizing rod is fixedly connected to each of the four corners of the bottom outer wall of the limiting frame, and the four stabilizing rods are slidably inserted into the inside of the worktable.

[0008] This device can stably restrict the position of different accumulator models and quickly adjust the housing to face different positions towards the operator. Combined with welding equipment, it enables rapid repair of the accumulator, allowing for quick deployment. Place the diaphragm accumulator on top of the abutment plate, then activate the electric telescopic rod to drive the limiting frame upwards. The limiting frame moves the abutment plate and accumulator closer to the support cover. Since the diameters of the accumulator ends differ, to better accommodate accumulator ends of different diameters, one support cover that cannot contact the accumulator end can be adjusted according to the actual situation. If the position of other operating parts of the accumulator changes, use the handle to drive the screw two to rotate. The screw two will then drive the abutment plate to slide along the limiting frame, causing the accumulator restricted by the support cover to begin rotating, with the damaged area facing the operator.

[0009] As a further preferred embodiment of this technical solution, the bottom of the workbench is provided with a number of equally spaced insertion holes, and two adjacent insertion holes are slidably connected to the same limiting pin, and the limiting pin is slidably connected inside the moving frame.

[0010] As a further preferred embodiment of this technical solution, each of the four support columns at the bottom of the workbench is equipped with a support assembly, the support assembly including rollers mounted on the outer wall of the bottom of the support column.

[0011] As a further preferred embodiment of this technical solution, a horizontally arranged extension plate is fixedly connected to the outside of the workbench support column, and a vertically arranged screw is threadedly connected inside the extension plate.

[0012] The rollers ensure that the device can be moved easily. After the movement is complete, the screw is driven to rotate along the extension plate, and its end position will be able to fit with the ground. The four screws can be adjusted individually, so that the device can adapt to different ground conditions and will not shake.

[0013] As a further preferred embodiment of this technical solution, several sliding rollers are installed in the V-shaped grooves of the support cover.

[0014] As a further preferred embodiment of this technical solution, the thread helix angle of the external thread of the lead screw is less than the equivalent friction angle.

[0015] This utility model provides a field welding repair device for diaphragm accumulators, which has the following beneficial effects:

[0016] (1) By setting a positioning component, this utility model can stably restrict the position of different types of accumulators and quickly adjust the different positions of the shell to face the operator. With the help of welding equipment, the accumulator can be quickly repaired and put into use. Place the diaphragm accumulator on the top of the abutment plate, then start the electric telescopic rod to drive the limit frame to move upward. The limit frame drives the abutment plate and the accumulator to move closer to the support cover. Since the diameter of the accumulator end is different, in order to make the support cover better fit the accumulator end with different diameters, the support cover that cannot contact the accumulator end can be adjusted according to the actual situation. If the position of other operating parts of the accumulator changes, use the handle to drive the screw two to rotate. The screw two can drive the abutment plate to slide along the limit frame. The accumulator restricted by the support cover will start to rotate, and the damaged position will also face the operator.

[0017] (2) By setting up a support component, the roller can ensure that the device can be moved easily. After the movement is completed, the screw is driven to rotate along the extension plate, and its end position can be in contact with the ground. The four screws can be adjusted separately so that the device can adapt to different ground conditions and will not shake. Attached Figure Description

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] This utility model provides a technical solution: such as Figure 2 , Figure 3 and Figure 4 As shown, in this embodiment, a field welding repair device for a diaphragm accumulator includes a workbench 1. Welding equipment, including a welding machine, a welding torch, and a grounding clamp, is fixedly installed on the top outer wall of the workbench 1. A positioning assembly 2 is installed on the top of the workbench 1. The positioning assembly 2 includes an electric telescopic rod 207 fixedly installed on the top outer wall of the workbench 1. A horizontally positioned limiting frame 208 is fixedly connected to the output end of the electric telescopic rod 207. A sliding groove 201 is provided on both sides of the top outer wall of the workbench 1. A movable frame 202 is slidably inserted into each of the two sliding grooves 201. A vertically positioned lead screw 203 is rotatably connected inside each of the two movable frames 202. A horizontally positioned support cover 205 is threaded onto the outside of each of the two lead screws 203. The bottom outer wall of the support cover 205 has a V-shaped opening. The limiting groove is fixedly connected to two vertically arranged guide rods 204 inside each of the two moving frames 202. The support cover 205 is slidably sleeved on the outside of the two guide rods 204 inside the corresponding moving frame 202. The diaphragm accumulator is placed on the top of the abutment plate 211. Then, the electric telescopic rod 207 is started to drive the limiting frame 208 to move upward. The limiting frame 208 drives the abutment plate 211 and the accumulator to move closer to the support cover 205. Since the diameter of the accumulator end is different, in order to make the support cover 205 better fit the accumulator end with different diameters, the support cover 205 that cannot contact the accumulator end can be adjusted according to the actual situation. The screw 203 is rotated by the knob, and the support cover 205 is driven by the screw 203 to move downward along the guide rod 204, thereby completing the fixation.

[0025] The limiting frame 208 is internally connected to a horizontally arranged lead screw 210. The lead screw 210 is externally threaded with an abutment plate 211, and the lower half of the abutment plate 211 is in contact with the inner wall of the limiting frame 208. Each of the four corners of the bottom outer wall of the limiting frame 208 is fixedly connected to a stabilizing rod 209, and the four stabilizing rods 209 are slidably inserted into the workbench 1. If the position of other operating parts of the accumulator changes, the lead screw 210 can be rotated by using the handle. The lead screw 210 can then drive the abutment plate 211 to slide along the limiting frame 208. The accumulator, which is restricted by the support cover 205, will then start to rotate, and the injured area will face the worker.

[0026] The bottom of the workbench 1 has several equally spaced insertion holes 212. Two adjacent insertion holes 212 are slidably connected to the same limiting pin 213, and the limiting pin 213 is slidably connected inside the moving frame 202. If the accumulator is large, the limiting pin 213 can be pulled out from inside the insertion hole 212, and the moving frame 202 can slide inside the slide groove 201. After the adjustment is completed, the moving frame 202 can be fixed again by using the limiting pin 213.

[0027] like Figure 1 and Figure 2 As shown, each of the four support columns at the bottom of the workbench 1 is equipped with a support assembly 3, and the support assembly 3 includes a roller 301 installed on the outer wall of the bottom of the support column.

[0028] The workbench 1 has a horizontally fixed extension plate 302 externally connected to the support column, and a vertically fixed screw 303 is internally threaded to the extension plate 302.

[0029] The rollers 301 ensure that the device can be moved easily. After the movement is completed, the screws 303 are driven to rotate along the extension plate 302, and their ends can be in contact with the ground. The four screws 303 can be adjusted individually so that the device can adapt to different ground conditions and will not shake.

[0030] like Figure 4 As shown, several sliding rollers 206 are installed in the V-shaped groove of the support cover 205, which helps to reduce the friction between the accumulator end and the support cover 205, thereby ensuring that the adjustment process is easy enough.

[0031] like Figure 4 As shown, the thread helix angle of the external thread of the lead screw 203 is less than the equivalent friction angle, giving it a self-locking property, thereby ensuring that the position of the support cover 205 will not change arbitrarily due to external forces.

[0032] This utility model provides an on-site welding repair device for diaphragm accumulators, the specific working principle of which is as follows:

[0033] When the device is in operation, place the diaphragm accumulator on top of the abutment plate 211. Then, activate the electric telescopic rod 207 to drive the limiting frame 208 upward. The limiting frame 208 moves the abutment plate 211 and the accumulator closer to the support cover 205. Since the diameters of the accumulator ends are different, in order to better adapt the support cover 205 to the accumulator ends of different diameters, one of the support covers 205 that cannot contact the accumulator ends can be adjusted according to the actual situation. By rotating the knob to drive the lead screw 203, the support cover 205 will be driven by the lead screw 203 to move downward along the guide rod 204, thereby completing the fixation. If the accumulator model is large, pull the limiting pin 213 out of the insertion hole 212. The movable frame 202 can slide inside the slide groove 201. After adjustment, the movable frame 202 can be fixed again by the limit pin 213. If the position of other operating parts of the accumulator changes, the screw 210 can be rotated by the handle. The screw 210 can drive the abutment plate 211 to slide along the limit frame 208. The accumulator restricted by the support cover 205 will start to rotate, and the injured position will face the worker. The roller 301 can ensure that the device can be moved easily. After the movement is completed, the screw 303 is driven to rotate along the extension plate 302. Its end position can be in contact with the ground, and the four screws 303 can be adjusted separately so that the device can adapt to different ground conditions and will not shake.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
