Description

Technical Field

[0001] This invention relates to the field of water sprinkler vehicle pipeline technology, specifically to a simulation assembly tooling for a water sprinkler vehicle pipeline system and its assembly method. Background Technology

[0002] The sprinkler vehicle piping system simulation assembly fixture refers to a professional tool used to simulate and test the internal piping system of sprinkler vehicles. It consists of components such as pipes, valves, and pumps, and can reproduce the layout and working state of the vehicle's piping. This allows engineers to evaluate the performance, reliability, and safety of the piping system before vehicle assembly through the fixture's simulation test, ensuring that it operates normally in actual use and guaranteeing the quality and reliability of the sprinkler vehicle piping system. The piping system of a sprinkler truck consists of several pipes spliced ​​and welded together. These pipes are usually cylindrical, which results in a small contact area between the pipes and the processing platform. This makes them susceptible to slippage due to vibrations generated during processing and testing, requiring the pipes to be redeployed before processing or testing can continue. This, in turn, affects the smooth progress of pipe processing and testing. To address this, we propose a simulated assembly fixture and assembly method for the piping system of a sprinkler truck. Summary of the Invention

[0003] The purpose of this invention is to provide a simulation assembly tool for a water sprinkler vehicle pipeline system to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention is a simulation assembly tool for a sprinkler vehicle pipeline system, including a simulation mechanism for installing the pipeline system; The simulation mechanism includes a push rod, several fixed plates, and a lower groove plate; A connecting block is installed on the top output end of the push rod. The top of the connecting block is an arc surface. A side plate is installed on the back of the connecting block, and a side plate is installed on the front of the connecting block. The top right side of the side plate is rotatably connected to the top cover plate. Each of the fixed plates has a tray installed on its outer side wall, and a quick clamp is installed at the top center of the fixed plate. A circular arc plate is provided on the right side of the lower groove plate, and a circular arc plate is provided on the top of the circular arc plate. The side plate and the top cover plate are connected by a pin, and the side plate and the top cover plate are rotatably connected to each other by the pin.

[0005] Furthermore, the simulation mechanism includes a simulation component for placing several components of the piping system; A locking component is disposed on the left side of the simulation component, and the locking component is used to lock the top part of the pipe; A clamping assembly is disposed on top of the simulation assembly and is used to squeeze and position the pipe assembly; An auxiliary component is disposed at the center of the simulation component. The auxiliary component is used to press the pipe assembly from the center to prevent it from curling due to excessive length. The bottom outer wall of the clamping component and the auxiliary component abuts against the top outer wall of the simulation component.

[0006] Furthermore, the simulation component includes a device body, the top of which is equipped with a plurality of perforated plates, and the top of which is provided with a plurality of pipes. The two perforated plates on the left are larger than the two perforated plates on the right, and the top of each perforated plate has several cylindrical holes.

[0007] Furthermore, the locking assembly includes a push rod, which is located at the bottom center of the leftmost perforated plate. A connecting rod is installed at the center of the left outer wall of the top cover plate. A rectangular plate is provided at the top left of the connecting block. The side outer wall of the rectangular plate is installed on side plate one, and the front outer wall of the rectangular plate is installed on the back outer wall of side plate two. By providing a connecting piece on the outside of the push rod, it can be positioned to prevent the push rod from shifting during operation, which would cause the top-mounted connecting block, top cover plate and pipe to rub against each other. The outer wall of the connector sleeved on the outer side of the push rod is mounted on the outer wall of the device body.

[0008] Furthermore, a rectangular protrusion is installed at the bottom center of the connecting rod. Hollow protrusions are provided on both the front and back sides of the rectangular protrusion. The right outer walls of both hollow protrusions are installed on the left outer wall of the rectangular plate. The two hollow protrusions are mirror images of each other with the rectangular protrusion as the center. The interiors of both hollow protrusions are hollow. A trapezoidal slider is slidably connected to the inner wall of each hollow protrusion. A pull rod is installed at the center of the trapezoidal slider. The sides of the two trapezoidal sliders that are close to each other extend through to the center of the rectangular protrusion. The front and back sides of the pull rod extend outward through the hollow protrusion and are slidably connected. Springs are sleeved on the outer sides of the outer walls of both pull rods. By providing an annular opening at the end of the pull rod, it is convenient for the operator to control the displacement of the pull rod and the trapezoidal slider by pulling the annular opening at the end of the pull rod. The hollow protrusion's inner wall is flexibly connected to the trapezoidal slider via a spring, and the pull rod is adapted to the size of the hole through which the hollow protrusion and rectangular protrusion are penetrated.

[0009] Furthermore, the clamping assembly includes a U-shaped push plate, which is disposed at the top center of the tray one. Several trays one are disposed near the pipe flange. The outer side wall of the U-shaped push plate contacts the pipe flange. The center of the U-shaped push plate on the side away from the pipe is mounted on the coupling at the bottom output end of the quick clamp one. The silicone setting of the clamping block can absorb the downward pressing pressure of the quick clamp two, preventing the quick clamp two from having excessive downward pressure and causing damage to the pipe. The clamping assembly includes several trays 2. The bolts of the tray 1 and the fixing plate pass through the cylindrical holes of the perforated plate and extend downward. The fixing plate and the tray 1 are locked to the perforated plate by bolts and threads.

[0010] Furthermore, several of the aforementioned tray boxes 2 are disposed on the side of the outer wall of the pipe. A quick clamp 2 is installed at the top center of the tray box 2, and a clamping block is installed on the coupling at the bottom output end of the quick clamp 2. By setting tray box 1 and tray box 2 to be locked to the perforated plate with bolts, it is convenient for the staff to flexibly adjust the position of tray box 1 and tray box 2 according to the opening on the perforated plate and the layout of the pipe. The bottom outer wall of the clamping block contacts the top outer wall of the pipe. The clamping block is shaped like a frustum and is made of silicone.

[0011] Furthermore, the auxiliary component includes an upper groove plate, which is located at the center of one side of the arc plate and the second arc plate, and is positioned on top of the lower groove plate. The lower groove plate is installed on the top left outer wall of the second perforated plate from the right. A lead screw is rotatably connected to the center of the front of the first and second arc plates, and an arc plate is rotatably connected to the center of the back of the first and second arc plates. Both the lead screw and the slide rail pass through the upper groove plate. The lead screw is threaded to the upper groove plate, and the slide rail is slidably connected to the upper groove plate. A knob is installed at the center of the top of the lead screw. By setting two support rods, additional support force can be provided to the second arc plate from the right side, ensuring that the first and second arc plates are on the same horizontal line. Among them, support rods are installed on the front and back of the left outer wall of the second arc plate. The two support rods are mirrored with the second arc plate as the center. The bottom outer wall of the support rod is installed on the top outer wall of the second perforated plate from the right.

[0012] The present invention has the following beneficial effects: (1) The present invention sets a locking component, specifically placing the pipe on the arc surface of the top of the connecting block, then rotating the top cover plate to align the rectangular protrusion with the hollow protrusion, and then releasing the pull rod so that the spring resets and inserts it into the rectangular protrusion. In this way, the pipe can be fixed on the arc surface of the connecting block, preventing the pipe from sliding due to vibration generated during processing and testing, and ensuring that the processing and testing of the pipe can be carried out smoothly.

[0013] (2) The present invention sets up a clamping assembly, specifically by using bolts to lock the fixing plate, tray one and tray two on the perforated plate, so that quick clamp one is aligned with the pipe flange and quick clamp two is aligned with the top outer wall of the pipe. Then, several quick clamps one and quick clamp two are pulled on one side, so that the U-shaped push plate and clamping block squeeze the pipe. In this way, the splicing between several pipes can be quickly positioned, which makes it convenient for workers to flexibly adjust the layout of several pipes. It is convenient for workers to determine the optimal pipe layout of the sprinkler vehicle pipe system through testing, and ensures the reliability of the pipe system in actual use.

[0014] (3) The present invention sets up an auxiliary component, specifically by rotating the knob clockwise to rotate the lead screw, so that the lead screw can drive the upper groove plate to move through the threaded connection between the lead screw and the upper groove plate, so that the upper groove plate moves downward along the slide rail and finally converges with the lower groove plate at the bottom. In this way, the end of the pipe can be fixed at the center of the groove of the lower groove plate and the upper groove plate, preventing the end of the pipe with a longer size from warping, thereby avoiding the shaking caused by the warping of the end, and ensuring that the processing and testing of the pipe can be carried out smoothly.

[0021] The simulation mechanism 1 includes a simulation component 11, which is used to place several components of the piping system; Locking component 12 is located to the left of simulation component 11 and is used to lock the top part of the pipe; Clamping assembly 13 is disposed on top of simulation assembly 11 and is used to squeeze and position the pipe assembly. The auxiliary component 14 is located at the center of the simulation component 11. The auxiliary component 14 is used to press the pipe assembly from the center to prevent it from curling due to excessive length. The bottom outer wall of the clamping component 13 and the auxiliary component 14 abuts against the top outer wall of the simulation component 11.

[0022] The simulation component 11 includes a device body 111. Several perforated plates 112 are installed on the top of the device body 111, and several pipes 113 are provided on the top of the perforated plates 112. The two perforated plates 112 on the left are larger than the two perforated plates 112 on the right, and several cylindrical holes are opened on the top of the perforated plates 112.

[0023] The locking assembly 12 includes a push rod 121, which is located at the bottom center of the leftmost perforated plate 112. A connecting rod 1251 is installed at the center of the left outer wall of the top cover plate 124. A rectangular plate 1261 is provided on the top left side of the connecting block 122. The side outer wall of the rectangular plate 1261 is installed on the first side plate 1231, and the front outer wall of the rectangular plate 1261 is installed on the back outer wall of the second side plate 1232. The outer wall of the connector sleeved on the outside of the push rod 121 is installed on the outer wall of the device body 111.

[0024] A rectangular protrusion 1252 is installed at the bottom center of the connecting rod 1251. Hollow protrusions 1262 are provided on both the front and back of the rectangular protrusion 1252. The right outer walls of the two hollow protrusions 1262 are installed on the left outer wall of the rectangular plate 1261. The two hollow protrusions 1262 are mirror images of the rectangular protrusion 1252. The interiors of the two hollow protrusions 1262 are hollow. A trapezoidal slider 127 is slidably connected to the inner wall of the hollow protrusion 1262. A pull rod 128 is installed at the center of the trapezoidal slider 127. The sides of the two trapezoidal sliders 127 that are close to each other extend through to the center of the rectangular protrusion 1252. The front and back of the pull rod 128 extend outward through the hollow protrusion 1262 and are slidably connected. Springs are fitted on the outer sides of the outer walls of the pipes. By setting the locking assembly 12, the pipe 113 is placed on the arc surface of the top of the connecting block 122. Then, the top cover plate 124 is rotated to align the rectangular protrusion 1252 with the hollow protrusion 1262. Then, the pull rod 128 is released and inserted into the rectangular protrusion 1252 under the action of the spring's reset. This fixes the pipe 113 on the arc surface of the connecting block 122, preventing the pipe 113 from sliding due to vibrations generated during processing and testing, and ensuring that the processing and testing of the pipe 113 can be carried out smoothly. The inner wall of the hollow protrusion 1262 is flexibly connected to the trapezoidal slider 127 by a spring. The size of the pull rod 128 is compatible with the size of the hole through which the hollow protrusion 1262 and the rectangular protrusion 1252 are penetrated.

[0025] The clamping assembly 13 includes a U-shaped push plate 134, which is located at the top center of tray 132. Several trays 132 are located near the flange of pipe 113. The outer side wall of the U-shaped push plate 134 contacts the flange of pipe 113. The center of the side of the U-shaped push plate 134 away from pipe 113 is mounted on the coupling at the bottom output end of quick clamp 133. The clamping assembly 13 includes several trays 2 135. The bolts of tray 132 and fixing plate 131 pass through the cylindrical hole of perforated plate 112 and extend downward. Fixing plate 131 and tray 132 are threadedly locked to perforated plate 112 with bolts.

[0026] Several trays 135 are installed on the side of the outer wall of pipe 113. A quick clamp 136 is installed at the top center of tray 135. A clamping block 137 is installed on the coupling at the bottom output end of quick clamp 136. The fixing plate 131, tray 132, and tray 135 are locked to the perforated plate 112 with bolts, so that quick clamp 133 is aligned with the flange of pipe 113, and quick clamp 136 is aligned with the top outer wall of pipe 113. Then, several quick clamps 133 and quick clamps are pulled from one side. The U-shaped push plate 134 and clamping block 137 compress the pipe 113, which allows for quick positioning of the splicing between several pipes 113. This facilitates flexible adjustment of the layout of several pipes 113 by the staff, and makes it easier for the staff to determine the optimal pipe layout of the sprinkler vehicle pipe system through testing, ensuring the reliability of the pipe system in actual use. The bottom outer wall of the clamping block 137 contacts the top outer wall of the pipe 113. The clamping block 137 is shaped like a frustum and is made of silicone.

[0027] The auxiliary component 14 includes an upper groove plate 143, which is located at the center of one side of the arc plate 1421 and the arc plate 2 1422. The upper groove plate 143 is located on top of the lower groove plate 141, which is installed on the top left outer wall of the second perforated plate 112 from the right. A lead screw 1441 is rotatably connected to the front center of the arc plate 1421 and the arc plate 2 1422, and an arc plate 2 1422 is rotatably connected to the back center of the arc plate 1421 and the arc plate 2 1422. The lead screw 1441 and the slide rail 1442 both pass through the upper groove plate 143. The lead screw 1441 is threaded to the upper groove plate 143, and the slide rail 1442 is slidably connected to the upper groove plate 143. A knob 145 is installed at the top center of the lead screw 1441. Rotating the knob 145 clockwise... 45. Rotate the lead screw 1441, causing it to move through the threaded connection with the upper groove plate 143. This causes the upper groove plate 143 to move downward along the slide rail 1442 and eventually converge with the lower groove plate 141 at the bottom. This fixes the end of the pipe 113 at the center of the groove between the lower groove plate 141 and the upper groove plate 143, preventing the ends of longer pipes from warping and avoiding shaking caused by end warping. This ensures that the processing and testing of the pipe 113 can be carried out smoothly. Support rods 146 are installed on the front and back of the left outer wall of the arc plate 2 1422. The two support rods 146 are mirror images of the arc plate 2 1422. The bottom outer wall of the support rods 146 is installed on the top outer wall of the second perforated plate 112 from the right.

[0028] In use, firstly, several pipes 113 are placed on the four perforated plates 112 on the top of the device body 111. Then, the arrangement of the pipes 113 is adjusted according to the design plan so that the layout of the pipes 113 conforms to the design plan. Then, the knob 145 is turned, causing the knob 145 to drive the lead screw 1441 installed at the bottom to rotate. This causes the lead screw 1441 to move vertically through the internal thread of the upper groove plate 143. When moving, the upper groove plate 143 slides downward along the slide rail 1442 and, with the cooperation of the lower groove plate 141, moves the pipes 113. 3. Position and clamp the pipe, then pull the lever 128 outward to lock the hollow protrusion 1262 and the rectangular protrusion 1252 into contact. Then open the top cover plate 124 and place the vertically arranged pipe 113 on the curved surface of the connecting block 122. Then rotate the top cover plate 124 to make the rectangular protrusion 1252 and the hollow protrusion 1262 on the same horizontal line. Then release the lever 128 so that the spring drives the lever 128 to reset and insert it into the rectangular protrusion 1252, so that the rectangular protrusion 1252 and the hollow protrusion 1262 are locked together again to prevent the pipe 113 from slipping off accidentally. Finally, the fixing plate 131, tray one 132, and tray two 135 are locked to the top of the perforated plate 112 with bolts, allowing the flange of the pipe 113 to be inserted into tray one 132, and aligning the output end of quick clamp one 133 with the flange of the pipe 113, so that the pipe 113 is inserted into the arc groove of tray two 135, and aligning the bottom output end of quick clamp two 136 with the center of the top of the pipe 113. Then, several quick clamps one 133 and quick clamp two 136 are pulled in sequence, causing the output end of quick clamp one 133 to push the U-shaped push plate 134 to move, and through the U-shaped push plate 134 and... The tray 132 clamps the flange of the pipe 113. When the quick clamp 136 is pulled, the quick clamp 136 will press the pipe 113 through the clamping block 137 at the bottom, thus initially positioning the pipe 113. Then, the layout of the pipe 113 is tested to confirm the safety and reliability of the layout in actual use. Then, the layout of the pipe 113 is adjusted in a timely manner based on the test data. After the layout adjustment is completed, several pipes 113 are welded together using welding tools. Then, the welded pipes 113 are removed and several components of the simulation mechanism 1 are disassembled in sequence.

9. An assembly method for a water sprinkler vehicle piping system simulation assembly fixture, employing the water sprinkler vehicle piping system simulation assembly fixture as described in claim 8, characterized in that: The assembly method includes the following steps: Step 1: Place several pipes (113) on the four perforated plates (112) on the top of the device body (111), and then adjust the arrangement of the pipes (113) according to the design plan so that the layout of the several pipes (113) conforms to the design plan. Step 2: Rotate the knob (145) to drive the lead screw (1441) installed at the bottom to rotate, and then drive the lead screw (1441) to make vertical displacement in the vertical direction through the internal thread of the upper groove plate (143). When the upper groove plate (143) moves, it will slide down along the slide rail (1442) and, with the cooperation of the lower groove plate (141), position and clamp the pipe (113). Step 3: Pull the lever (128) outward to lock the hollow protrusion (1262) and the rectangular protrusion (1252) into contact. Then open the top cover (124) and place the vertically positioned pipe (113) on the curved surface of the connecting block (122). Then rotate the top cover (124) to make the rectangular protrusion (1252) and the hollow protrusion (1262) on the same horizontal line. Then release the lever (128) so that the spring drives the lever (128) to reset and insert it into the rectangular protrusion (1252) so that the rectangular protrusion (1252) and the hollow protrusion (1262) are locked together again to prevent the pipe (113) from slipping off accidentally. Step 4: Secure the fixing plate (131), tray one (132), and tray two (135) to the top of the perforated plate (112) using bolts. Insert the flange of the pipe (113) into tray one (132) and align the output end of quick clamp one (133) with the flange of the pipe (113). Insert the pipe (113) into the arc groove of tray two (135), and align the bottom output end of quick clamp two (136) with the center of the top of the pipe (113). Pull several quick clamps (133) and quick clamps (136) in sequence to make the output end of quick clamp (133) push the U-shaped push plate (134) to move, and clamp the flange of the pipe (113) through the U-shaped push plate (134) and the tray (132). When quick clamp (136) is pulled, quick clamp (136) will press the pipe (113) through the clamping block (137) at the bottom, so as to perform preliminary positioning of the pipe (113). Step 5: Test the layout of the pipes (113) to confirm the safety and reliability of the layout in actual use. Then, adjust the layout of the pipes (113) in a timely manner based on the test data. After the layout adjustment is completed, use welding tools to weld several pipes (113) together. Then, take out the welded pipes (113) and dismantle several components of the simulation mechanism (1) in sequence.
