Description

Technical Field

[0001] This invention relates to the field of MPP cable protection pipe technology, specifically to a mobile device for MPP cable protection pipes. Background Technology

[0002] MPP (modified polypropylene) cable protection pipe is a type of plastic pipe made from modified polypropylene as the main raw material through extrusion molding. It is divided into ordinary type and reinforced type. This pipe has the characteristics of high temperature resistance, external pressure resistance and good insulation performance. In practical applications, MPP pipes are usually buried underground, and pipelines are laid through trenchless technology to cross obstacles such as roads and buildings. Compared with the traditional trenching and burying method, it has the advantages of high construction efficiency and less environmental impact. In storage and construction sites, multiple MPP pipes usually need to be stacked and stored, and pipe supports or special stacking racks are often used for stacking to reduce the space occupied.

[0003] The existing MPP pipe moving device has a fundamental contradiction between stacking height and material retrieval convenience. To improve the efficiency of a single transport, the number of stacking layers needs to be increased. However, after stacking at a high level, it is difficult for operators to directly take the upper layer of pipes. The lower layer of pipes can only be taken out after all the upper layers have been unloaded, which makes the unloading operation extremely cumbersome. At the same time, the device movement, roller locking and material retrieval preparation need to be operated separately, and it is impossible to complete the transition to the unloading state at the same time as stopping and fixing, which seriously affects the efficiency of on-site construction. Summary of the Invention

[0004] The purpose of this invention is to provide an MPP cable protection pipe moving device to solve the problems mentioned in the background art, such as the difficulty in retrieving upper-layer pipes from high-rise stacks, and the need to manually lock and stop the vehicle when retrieving the pipes, which is quite cumbersome.

[0005] To achieve the above objectives, the present invention provides the following technical solution: An MPP cable protection pipe moving device includes a mounting plate. A housing is fixedly connected to the upper end of the mounting plate, and two mounting posts are fixedly connected to the upper end of the mounting plate. A storage shell is fixedly connected to the upper end of the two mounting posts. Multiple storage slots are provided inside the storage shells, and placement shells are slidably connected to each of the multiple storage slots. An expansion mechanism is provided on both sides of the housing. The expansion mechanism consists of multiple moving slots, multiple moving blocks, two moving rods, and two folding rods. The multiple moving slots are each located at one end of the housing and the storage shell. The multiple moving blocks are slidably connected to the multiple moving slots and fixedly connected to one end of each of the multiple placement shells. Two moving rods are fixedly connected to one end of each of the multiple moving blocks. One end of each of the two folding rods is rotatably connected to one end of each of the two moving rods via a pivot. A pulling and fixing mechanism is provided on one side of the mounting plate, which is used to pull the two folding rods downwards and fix them in place.

[0006] Furthermore, the pulling and fixing mechanism consists of a pull rod, a fixing block, a free block, a fixing shell, two mounting shells, a pull rod, two snap-fit ​​springs, two positioning blocks, and two positioning slots. The pull rod is fixedly connected to one end of the two folding rod shafts. The fixing block is fixedly connected to the outer surface of the pull rod. The free block is slidably connected to the outer surface of the pull rod. The fixing shell is fixedly connected to one end of the mounting plate. The two mounting shells are respectively fixedly connected to both ends of the fixing shell. The two positioning slots are respectively opened at both ends of the two fixing shells. The two snap-fit ​​springs are respectively fixedly connected to one inner wall of the two mounting shells. The two positioning blocks are respectively fixedly connected to one end of the two snap-fit ​​springs.

[0007] Furthermore, it also includes two sets of moving mechanisms. Each set of moving mechanisms consists of a moving frame, rollers, spline grooves, spline blocks, a diverter rod, a diverter pipe, and a diverter plate. The moving frame is fixedly connected to the lower end of the mounting plate. The rollers are rotatably connected to the lower end of the moving frame via a rotating rod. The spline groove is fixedly connected to one end of the rotating rod. The diverter pipe is fixedly connected to the lower end of the mounting plate. The diverter plate is slidably connected inside the diverter pipe. The diverter rod is fixedly connected to one end of the diverter plate. The spline block is fixedly connected to one end of the diverter rod, and the spline block is engaged with the spline groove.

[0008] Furthermore, a piston housing is fixedly connected to one end of the diverter tube, a lower pressure plate is slidably connected inside the piston housing, a lower pressure rod is fixedly connected to the upper end of the lower pressure plate, and an assembly plate is fixedly connected to the upper end of the lower pressure rod and the lower end of the lower pull rod.

[0009] Furthermore, a return spring is fixedly connected to the near end of the mounting plate and the assembly plate, and a foot pedal ring is fixedly connected to the lower end of the assembly plate.

[0010] Furthermore, it also includes two sets of support mechanisms. Each set of support mechanisms consists of a placement groove, two pull grooves, two moving columns, two support blocks, two push-pull flexible shafts, a moving plate, a magnetic plate, and a support column. The two pull grooves are located at the lower end of the storage shell and the lower inner wall of the outer shell. The placement groove is located at one end of the mounting plate. The two moving columns are fixedly connected to the lower end of one of the placement shells. The two support blocks are respectively fixedly connected to one end of the two moving columns. The two push-pull flexible shafts are respectively fixedly connected to one end of the two support blocks. The moving plate is fixedly connected to one end of the two push-pull flexible shafts. The support column is fixedly connected to one end of the moving plate. The magnetic plate is fixedly connected to one end of the mounting plate, and the magnetic plate is magnetically connected to the support column.

[0011] Furthermore, both the fixed block and the free block are trapezoidal, and the fixed block and the free block abut against the two positioning blocks.

[0012] Furthermore, telescopic rods are fixedly connected to the inner walls of one side of each of the two mounting shells, and the two snap-fit ​​springs are respectively sleeved on the circumferential surfaces of the two telescopic rods.

[0013] The technical solution provided by this invention has the following advantages compared with the known prior art: 1. This device stores MPP pipes by stacking multiple placement shells. When retrieving a pipe, pulling down the pull rod drives two folding rods to move to both ends via a rotating shaft, causing the moving blocks to slide. The moving blocks push each placement shell to unfold to both sides through the moving slots, exposing pipes of any height for direct retrieval. When pulled down, the fixed block passes through the positioning block and presses it into the placement shell. After passing through, the positioning block resets under the action of a spring, locking between the fixed block and the pull rod in the unfolded state. When resetting, pulling down again causes the free block to pass through the positioning block and be pressed in. Then, pushing up the pull rod causes the fixed block and free block to rise and disengage. The folding rod retracts, causing the placement shells to retract to the storage state, facilitating stacking and storage and preventing damage from stacking.

[0014] 2. The device supports and moves the mounting plate via rollers under the moving frame. When retrieving the pipe, the user must first step on the foot pedal ring to lower it, causing the assembly plate and pull rod to descend. The movement of the pull rod triggers a series of transmissions, unfolding the placement shell to facilitate the retrieval of the internal pipe. Simultaneously, the descent of the assembly plate moves the pressure rod and pressure plate downward, squeezing the liquid in the piston shell through the diversion pipe. This pushes the two diversion plates to move in opposite directions, thereby causing the diversion rod and spline block to move synchronously. The spline block then engages in the spline groove, locking the rollers and preventing the device from shaking. This design achieves simultaneous unfolding of the placement shell and locking of the rollers through a single foot pedal action, making it convenient to operate and highly stable.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0019] The present invention will be further described below with reference to embodiments.

[0020] A moving device for MPP cable protection pipes, such as Figures 1-7As shown, the system includes a mounting plate 101, with a housing 1 fixedly connected to its upper end. Two mounting posts 108 are also fixedly connected to the upper end of the mounting plate 101. A storage shell 102 is fixedly connected to the upper end of each of the two mounting posts 108. Multiple storage slots are provided inside the storage shell 102, and a placement shell 107 is slidably connected to each of these slots. Extension mechanisms are provided on both sides of the housing 1. These extension mechanisms consist of multiple moving slots 103, multiple moving blocks 104, two moving rods 105, and two folding rods 106. The multiple moving slots 103... 3 are all opened at one end of the outer shell 1 and the storage shell 102. Multiple moving blocks 104 are slidably connected in multiple moving slots 103 respectively, and multiple moving blocks 104 are fixedly connected to one end of multiple placement shells 107 respectively. Two moving rods 105 are fixedly connected to one end of multiple moving blocks 104. One end of each of the two folding rods 106 is rotatably connected to one end of the two moving rods 105 through a rotating shaft. A pulling and fixing mechanism is provided on one side of the mounting plate 101. The pulling and fixing mechanism is used to pull the two folding rods 106 down and fix them. The pulling and fixing mechanism consists of a pull rod 2, a fixing block 201, a free block 202, a fixing shell 203, two mounting shells 204, a pull rod 205, two snap-fit ​​springs 209, two positioning blocks 210, and two positioning grooves 211. The pull rod 2 is fixedly connected to one end of the rotating shaft of the two folding rods 106. The fixing block 201 is fixedly connected to the outer surface of the pull rod 205. The free block 202 is slidably connected to the outer surface of the pull rod 205. The fixing shell 203 is fixedly connected to one end of the mounting plate 101. The two mounting shells 204 are respectively fixedly connected to both ends of the fixing shell 203. The two positioning grooves 211 are respectively opened at both ends of the two fixing shells 203. The two snap-fit ​​springs 209 are respectively fixedly connected to one side of the inner wall of the two mounting shells 204. The two positioning blocks 210 are respectively fixedly connected to one end of the two snap-fit ​​springs 209.

[0021] In a specific embodiment of the present invention, MPP tubes can be placed and stored using multiple placement shells 107. When it is necessary to retrieve an MPP tube, the pull rod 2 can be pulled down, and two folding rods 106 can be moved to opposite ends via a rotating shaft. As the two folding rods 106 move to opposite ends, multiple moving blocks 104 can be moved to opposite ends synchronously via a rotating shaft. As the moving blocks 104 move, multiple placement shells 107 can be moved to opposite ends via multiple moving slots 103. At this time, the MPP tubes in the multiple placement shells 107 can be easily retrieved, and MPP tubes of any height can be selected at will, improving the convenience of retrieval. When the pull rod 2 is pulled, it causes the pull rod 205 to slide within the fixed housing 203. As the pull rod 205 descends, it simultaneously moves the fixed block 201 and the free block 202. When the fixed block 201 passes the fixed housing 203, it contacts the two positioning blocks 210 and abuts them, then retracts into the two housings 204. After the fixed block 201 passes the two positioning blocks 210, the two positioning blocks 210 contact the two free blocks 202, pushing them a certain distance towards the upper end of the pull rod 205 and stopping. At this point, the elastic expansion of the two snap-fit ​​springs 209 allows the two positioning blocks 210 to spring back and return to their initial positions. The two positioning blocks 210 then snap into the fixed block 201 and... The pull rod 205 is positioned in the middle, which fixes the position of the pull rod 2, thereby maintaining the unfolded state of the placement shell 107. This facilitates the removal of the pipes inside the placement shell 107. When resetting is required, the pull rod 205 can be pulled down again, causing the two free blocks 202 to pass through the two positioning blocks 210. Then, the pull rod 2 is pushed up again, causing the fixed block 201 and the free block 202 to move upward and disengage from the positioning block 210. Moving the pull rod 2 upward will reset the pipes. At this time, the two folding rods 106 will move synchronously towards each other, pulling multiple moving blocks 104 and multiple placement shells 107 back to the original position of the storage shell 102. This facilitates the storage and handling of MPP pipes, preventing excessive accumulation of MPP pipes that could lead to damage.

[0022] Preferably, the detailed description of the movement trajectory of the free block 202 is as follows: When pulled down for the first time, the fixed block 201 and the free block 202 move down with the pull rod 205. The fixed block 201 presses the positioning block 210 into the housing 204 and passes through. The positioning block 210 is reset and popped out under the action of the snap-fit ​​spring 209. Then the free block 202 contacts the positioning block 210. Because the positioning block 210 blocks it, the free block 202 cannot continue to move down, while the pull rod 205 continues to move down, causing the free block 202 to slide upward relative to the pull rod 205 to the limit position. At this time, the positioning block 210 is stuck between the fixed block 201 and the free block 202, preventing the pull rod 205 from moving up, thus achieving locking. When pulled down for the second time, the pull rod 205 moves down again, and the free block 202 slides down relative to the pull rod 205 to another limit position due to the obstruction of the positioning block 210, completely passing the positioning block 210; at this time, the push-pull lever 2 moves up, the fixed block 201 and the free block 202 move up, pressing the positioning block 210 in again and passing through, and then the positioning block 210 resets, realizing unlocking.

[0023] Please refer to the details. Figure 1-7It also includes two sets of moving mechanisms. Each set of moving mechanisms consists of a moving frame 3, a roller 301, a spline groove 309, a spline block 308, a diverter rod 307, a diverter pipe 305, and a diverter plate 306. The moving frame 3 is fixedly connected to the lower end of the mounting plate 101. The roller 301 is rotatably connected to the lower end of the moving frame 3 via a rotating rod. The spline groove 309 is fixedly connected to one end of the rotating rod. The diverter pipe 305 is fixedly connected to the lower end of the mounting plate 101. The diverter plate 306 is slidably connected inside the diverter pipe 305. The diverter rod 307 is fixedly connected to one end of the diverter plate 306. The spline block 308 is fixedly connected to one end of the diverter rod 307, and the spline block 308 is engaged with the spline groove 309. One end of the diverter pipe 305 is fixedly connected to a piston housing 303, and a lower pressure plate 304 is slidably connected inside the piston housing 303. A lower pressure rod 302 is fixedly connected to the upper end of the lower pressure plate 304, and an assembly plate 206 is fixedly connected to the upper end of the lower pressure rod 302 and the lower end of the pull rod 205. A return spring 207 is fixedly connected to the near end of the mounting plate 101 and the assembly plate 206, and a foot pedal ring 208 is fixedly connected to the lower end of the assembly plate 206.

[0024] In this embodiment: the mounting plate 101 can be supported and moved by multiple rollers 301 below the movable frame 3. When it is necessary to remove the pipe, the rollers 301 need to be locked first to ensure sufficient stability during removal. Then, the foot pedal ring 208 can be stepped on to move it downwards, and the assembly plate 206 and the pull rod 205 can be pulled down. At this time, the movement of the pull rod 205 will drive a series of workpieces to move, unfolding the placement shell 107 and removing the pipe inside. On the other hand, the descent of the assembly plate 206 will simultaneously drive the pressure rod 302 and... The lower pressure plate 304 descends synchronously, squeezing the liquid inside the piston housing 303 outward through the two diversion pipes 305, and pressing the two diversion plates 306 to move in opposite directions. At this time, the two diversion rods 307 and the two spline blocks 308 also move synchronously, causing the spline blocks 308 to engage with the spline groove 309, locking the spline groove 309 and the roller 301, thereby preventing the roller 301 from rotating and improving the stability of the device. The assembly plate 206 can be pulled back by the return spring 207. After the operator finishes picking up the material and releases the downward pressure on the foot pedal ring 208, the return spring... 207 retracts, pulling the assembly plate 206 upward, thereby simultaneously driving the pull rod 205 and the pressure rod 302 upward; the upward movement of the pull rod 205 causes the pull rod 2 and the folding rod 106 to retract, and then through the moving rod 105 and the moving block 104, the placement shells 107 of each layer slide horizontally towards the center along the moving groove 103, and finally all retract and stack inside the storage shell 102; at the same time, the upward movement of the pressure rod 302 causes the pressure plate 304 to slide upward inside the piston shell 303, so that the previously squeezed liquid flows back to the piston shell 303, and during the liquid return process, the diverter plate 306 Under negative pressure, the device moves towards the center, causing the diverter rod 307 and spline block 308 to slide towards the center simultaneously, so that the spline block 308 exits from the spline groove 309, releasing the lock on the roller 301. During the retraction of the placement shell 107, the moving column 401 fixed at its lower end moves inward accordingly, and the moving plate 404 is pulled upward along the magnetic suction plate 406 by the push-pull flexible shaft 403 and finally retracts horizontally into the placement groove 4. At the same time, the support column 405 is lifted off the ground and retracted. At this point, all components of the entire device are smoothly reset to the initial storage state, ready for the next transportation and material retrieval.

[0025] Please refer to the details. Figure 1-7It also includes two sets of support mechanisms. Each set of support mechanisms consists of a placement groove 4, two pull grooves 407, two moving columns 401, two support blocks 402, two push-pull flexible shafts 403, a moving plate 404, a magnetic suction plate 406, and a support column 405. The two pull grooves 407 are opened at the lower end of the storage shell 102 and the lower inner wall of the outer shell 1. The placement groove 4 is opened at one end of the mounting plate 101. The two moving columns 401 are fixedly connected to the lower end of one of the placement shells 107. The two support blocks 402 are respectively fixedly connected to one end of the two moving columns 401. The two push-pull flexible shafts 403 are respectively fixedly connected to one end of the two support blocks 402. The moving plate 404 is fixedly connected to one end of the two push-pull flexible shafts 403. The support column 405 is fixedly connected to one end of the moving plate 404. The magnetic suction plate 406 is fixedly connected to one end of the mounting plate 101, and the magnetic suction plate 406 is magnetically connected to the support column 405.

[0026] In this embodiment: when one of the placement shells 107 moves, it can drive the two moving columns 401 to move synchronously through the two pull grooves 407, thereby driving the two support blocks 402, the two push-pull flexible shafts 403, the moving plate 404, and the support column 405 to move synchronously. After the moving plate 404 completely leaves the placement groove 4, the influence of gravity will cause the moving plate 404 to be perpendicular to and attached to one end of the magnetic suction plate 406. Since the moving plate 404 and the magnetic suction plate 406 are magnetically connected, the continuous movement of the support block 402 will cause the moving plate 404 to slide down along the magnetic suction plate 406, and cause the push-pull flexible shaft 403 to bend. After the placement shell 107 is completely moved, the two moving columns 401 can move synchronously through the two pull grooves 407, thereby driving the two support blocks 402, the two push-pull flexible shafts 403, the two push-pull flexible shafts 403, and the two moving columns 402 can move synchronously through the two pull grooves 407, thereby driving the two moving columns 402, the two moving columns 402, the two moving columns 403, the two moving columns 404, and the two moving columns 405 can move synchronously through the two pull grooves 407, thereby driving the two moving columns 402, the two moving columns 404, and the two moving columns 405 can move synchronously through the two pull grooves 407, thereby driving the two moving columns 404, the two moving columns 405, and the two moving columns 406 can move synchronously through the two pull grooves 407, thereby driving the two moving columns 405, the two moving columns 406, and the two moving columns 405 can move synchronously through the two pull grooves 407, thereby driving the two moving columns 405 After the entire device is moved to the outside of the storage shell 102, the support column 405 will also move down to the same height as the roller 301 to prevent the center of gravity from shifting outward due to the outward movement of the placement shell 107, thus improving the placement stability of the device. When the placement shell 107 is retracted, the moving plate 404 will retract along the rounded corner of one end of the magnetic suction plate 406 into the placement groove 4. It should be noted that the push-pull flexible shaft 403 has the characteristics of bidirectional push-pull transmission and arbitrary bending, which makes it convenient for the support block 402 to push the moving plate 404 to move through the push-pull flexible shaft 403. When the moving plate 404 is attached to the magnetic suction plate 406, the push-pull flexible shaft 403 can be in a bent shape, which makes it convenient to continue to push or pull the moving plate 404.

[0027] Preferably, the operating sequence of the magnetic plate 406 and the movable plate 404 is further explained as follows: When one of the placement shells 107 moves outward, the movable column 401 drives the support block 402 and the push-pull flexible shaft 403 to move outward, thereby pulling the movable plate 404 to slide outward along the placement groove 4. When the center of gravity of the movable plate 404 is completely out of the support range of the placement groove 4, under the action of gravity, the movable plate 404 flips downward around the connection point between its rear end and the push-pull flexible shaft 403 until it adheres to the magnetic plate 406 fixedly installed at one end of the mounting plate 101. The magnetic plate 406 is made of permanent magnet material, and its magnetic force is sufficient to overcome the gravity of the movable plate 404 and the slight reaction force of the push-pull flexible shaft 403, ensuring that the movable plate 404 is stably attracted and will not be suspended or shaken. As the placement shell 107 continues to move outward, the push-pull flexible shaft 403 bends, and the support column 405 moves down with the moving plate 404 to the same height as the roller 301, providing auxiliary support. When the placement shell 107 is retracted, the push-pull flexible shaft 403 pulls the moving plate 404, causing it to overcome the magnetic force of the magnetic suction plate 406 and detach. The plate then slides upward along the guide radius of the magnetic suction plate 406 surface, finally retracting horizontally into the placement slot 4. The support column 405 is then lifted off the ground and retracted. The magnetic force of the magnetic suction plate 406 is designed to ensure both stable adsorption during deployment and smooth detachment during retrieval. Furthermore, the magnetic force of the magnetic plate 406 is designed to match the weight of the moving plate 404 and the bending resistance of the push-pull flexible shaft 403, ensuring that the moving plate 404 can be stably attracted in the unfolded state, and can be smoothly pulled away by the push-pull flexible shaft 403 when it is retrieved.

[0028] Preferably, the upper inner wall of the mounting groove 4 is provided with a rectangular groove, which is not shown in the figure. The edge of the groove is provided with a guide chamfer or a rounded transition to ensure that the moving plate 404 will not be stuck by the groove wall during the sliding process.

[0029] Please refer to the details. Figure 1-7 Both the fixed block 201 and the free block 202 are trapezoidal, and the fixed block 201 and the free block 202 abut against the two positioning blocks 210. Telescopic rods are fixedly connected to the inner walls of one side of the two mounting shells 204, and two snap-fit ​​springs 209 are respectively sleeved on the circumferential surfaces of the two telescopic rods.

[0030] In this embodiment: the trapezoidal shape of the fixed block 201 and the free block 202 facilitates the contact and stability of the fixed block 201, the free block 202 and the positioning block 210, and the telescopic rod can prevent damage caused by the bending deformation of the snap-fit ​​spring 209.

[0031] Working principle: MPP tubes can be placed and stored through multiple placement shells 107. When it is necessary to retrieve the MPP tube, the pull rod 2 can be pulled down, and the two folding rods 106 can be moved to opposite ends through the pivot. When the two folding rods 106 move to opposite ends, multiple moving blocks 104 can be moved to opposite ends synchronously through the pivot. As the moving blocks 104 move, multiple moving slots 103 can move multiple placement shells 107 to opposite ends. At this time, the MPP tubes in the multiple placement shells 107 can be easily retrieved, and MPP tubes of any height can be selected at will, improving the convenience of retrieval. When the pull rod 2 is pulled, it causes the pull rod 205 to slide within the fixed housing 203. As the pull rod 205 descends, it simultaneously moves the fixed block 201 and the free block 202. When the fixed block 201 passes the fixed housing 203, it contacts the two positioning blocks 210 and abuts them, then retracts into the two housings 204. After the fixed block 201 passes the two positioning blocks 210, the two positioning blocks 210 contact the two free blocks 202, pushing them a certain distance towards the upper end of the pull rod 205 and stopping. At this point, the elastic expansion of the two snap-fit ​​springs 209 allows the two positioning blocks 210 to spring back and return to their initial positions. The two positioning blocks 210 then snap into the fixed block 201 and... The pull rod 205 is positioned in the middle, which fixes the position of the pull rod 2, thereby maintaining the unfolded state of the placement shell 107. This facilitates the removal of the pipes inside the placement shell 107. When resetting is required, the pull rod 205 can be pulled down again, causing the two free blocks 202 to pass through the two positioning blocks 210. Then, the pull rod 2 is pushed up again, causing the fixed block 201 and the free block 202 to move upward and disengage from the positioning block 210. Moving the pull rod 2 upward will reset the pipes. At this time, the two folding rods 106 will move synchronously towards each other, pulling multiple moving blocks 104 and multiple placement shells 107 back to the original position of the storage shell 102. This facilitates the storage and handling of MPP pipes, preventing excessive accumulation of MPP pipes that could lead to damage.
