[0037] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0038] Please also read Figures 1 to 4 , the portable adjustment and installation device for double-wall corrugated pipes provided by the present invention is now described. The portable adjustment and installation device for double-wall corrugated pipes comprises an arc frame 1, a movable frame 2, an arc arm 3 and a pulling mechanism 4. The arc frame 1 is used to be mounted on the outside of the double-wall corrugated pipe, and the axial direction of the arc frame 1 is defined as the first direction; the movable frame 2 is arranged on one side of the arc frame 1 along the first direction, and the position of the movable frame 2 relative to the arc frame 1 has the freedom to be adjusted along the first direction; there are two arc arms 3, and the two arc arms 3 are relatively hingedly arranged on the movable frame 2, and the two arc arms 3 are used to be mounted on the outside of the double-wall corrugated pipe to be docked, and when the arc arm 3 is mounted on the outside of the double-wall corrugated pipe, the end of the arc arm 3 away from the movable frame 2 is located at the bottom of the double-wall corrugated pipe; the pulling mechanism 4 is installed on the arc frame 1, and is used to pull the arc arm 3 to move in the direction close to the arc frame 1.

[0039] The portable adjustment and installation device for double-walled corrugated pipes provided in this embodiment is compared with the prior art. The arc frame 1 is provided with a plurality of arc ribs with openings facing downwards. The plurality of arc ribs are arranged at intervals along the first direction and are arranged relative to the arc groove on the outer side of the double-walled corrugated pipe, so as to ensure the stability of the position of the arc frame 1 installed on the double-walled corrugated pipe. A mobile frame 2 is installed on one side of the arc frame 1 along the first direction, and two arc arms 3 are hingedly arranged on the mobile frame 2. One end of the arc arm 3 is hingedly arranged on the mobile frame 2, so that the arc arm 3 can be rotated to the bottom of the double-walled corrugated pipe, and the length of the arc arm 3 can be increased, thereby increasing the clamping length between the arc arm 3 and the double-walled corrugated pipe. In the present application, during on-site construction, the arc frame 1 can be installed to the end of the fixed double-walled corrugated pipe, and then the mobile frame 2 can be installed to the double-walled corrugated pipe to be docked. By flipping the arc arm 3, the arc arm 3 can be clamped to the inside of the arc groove on the double-walled corrugated pipe to be docked. The moving frame 2 is stably connected to the double-walled corrugated pipe, and then the pulling mechanism 4 is used to pull the two arc-shaped arms 3 on the moving frame 2 to move toward the arc-shaped frame 1. By hingedly mounting the arc-shaped arms 3 on the moving frame 2, the connection area between the arc-shaped arms 3 and the double-walled corrugated pipe can be effectively increased, the stability of the movement of the double-walled corrugated pipe during the docking process can be ensured, and the docking quality and efficiency can be improved.

[0040] Specifically, in this embodiment, an arc-shaped positioning portion that is compatible with the curvature of the arc-shaped arm 3 is provided at the bottom of the movable frame 2. When the movable frame 2 is installed on the double-wall corrugated pipe, it can be first installed in the groove on the outside of the double-wall corrugated pipe through the arc-shaped positioning portion, and then the arc-shaped arm 3 is flipped to the inside of the arc-shaped grooves on both sides of the double-wall corrugated pipe.

[0041] In some embodiments, the arc-shaped arm 3 may be Figure 1 , Figure 2 See also Figure 1 , Figure 2 , a connecting rod 31 is fixedly mounted on the arc-shaped arm 3, and the end of the connecting rod 31 is hingedly mounted on the mobile frame 2. A limiting rod 32 extending in the direction close to the mobile frame 2 is also arranged at the connection between the arc-shaped arm 3 and the connecting rod 31. The end of the limiting rod 32 can abut against the mobile frame 2, and a limiting piece 5 is also movably arranged on the mobile frame 2. The limiting piece 5 can slide out of the mobile frame 2 to limit the limiting rod 32 to swing in the direction away from the mobile frame 2. The connecting rod 31 is fixedly mounted on the top of the arc-shaped arm 3, and the other end of the connecting rod 31 is hingedly mounted on the mobile frame 2. The end of the arc-shaped arm 3 connected to the connecting rod 31 is extended in the direction close to the mobile frame 2. The limiting rod 32 and the arc-shaped arm 3 are arc structures with the same curvature. The end of the limiting rod 32 can abut against the mobile frame 2, and the two arc-shaped arms 3 can be limited to flip in a direction close to each other. When the ends of the two arc-shaped arms 3 are against the moving frame 2, there is an opening between the bottom ends of the two arc-shaped arms 3 for accommodating the double-walled corrugated pipe, so that when the moving frame 2 is placed, the two arc-shaped arms 3 can be first opened and then closed to the outside of the double-walled corrugated pipe under the guidance of the double-walled corrugated pipe, so that the moving frame 2 can be placed on the double-walled corrugated pipe.

[0042] Preferably, in this embodiment, a guide wheel is rotatably provided at the bottom end of the arc-shaped arm 3 for abutting against the outer side of the double-wall corrugated pipe.

[0043] Specifically, in this embodiment, a limiting piece 5 is slidably arranged on the mobile frame 2, and the inner side surface of the limiting piece 5 is an arc-shaped structure adapted to the outer side surface of the limiting rod 32. When the limiting piece 5 slides out of the mobile frame 2, it can abut against the outer side surface of the limiting rod 32, so that the arc-shaped arm 3 can be limited inside the groove outside the double-wall corrugated pipe. The stability of the position of the arc-shaped arm 3 inside the groove is improved during the pulling process.

[0044] Preferably, in this embodiment, when the limiting piece 5 moves outward from the mobile frame 2, the limiting piece 5 can abut against the outside of the limiting rod 32, and at the same time push the limiting rod 32 to swing in the direction close to the double-walled corrugated pipe, so that the arc-shaped arm 3 can effectively fit the outside of the double-walled corrugated pipe, and in this embodiment, a chamfer is provided on the inner side of the arc-shaped arm 3 to facilitate sliding into the inside of the groove of the double-walled corrugated pipe, so as to ensure the stability of the position of the arc-shaped arm 3 inside the groove outside the double-walled corrugated pipe. In this way, the stability of the moving position of the double-walled corrugated pipe during the pulling process is ensured, and the docking accuracy is ensured.

[0045] In some embodiments, the above-mentioned limit plate 5 can be used as follows Figure 1 , Figure 2 See also Figure 1 , Figure 2 , a pushing assembly 51 for pushing the limiting piece 5 to slide out of the moving frame 2 is provided on the moving frame 2, and the pushing assembly 51 includes a gear 511 and a pushing rod 512. The gear 511 is rotatably arranged on the moving frame 2, and the limiting piece 5 is provided with teeth that mesh with the gear 511; the pushing rod 512 is slidably arranged on the moving frame 2, and the pushing rod 512 is meshed with the gear 511. Gears 511 are rotatably arranged on both sides of the arc-shaped arm 3 provided on the moving frame 2, the limiting piece 5 is located below the gear 511, and the outer side surface of the limiting piece 5 is provided with teeth that mesh with the gear 511. And the gears 511 on both sides are meshed with the pushing rod 512, and the pushing rod 512 is slidably arranged on the moving frame 2 in the vertical direction. When in use, the pushing rod 512 can be pushed up and down to drive the gear 511 to rotate. When the gear 511 rotates, the limiting piece 5 can be driven to move on the moving frame 2. The structure is simple and the operation is convenient. By setting the limiting piece 5, the movable frame 2 can be clamped and fixed on the double-wall corrugated pipe through the arc arms 3 on both sides.

[0046] Preferably, in this embodiment, a cross bar is fixedly connected between the push rods 512 corresponding to the two gears 511, and the push rods 512 on both sides can be driven to move together synchronously by pushing the cross bar up and down.

[0047] In some embodiments, the push rod 512 may be Figure 2 See the structure shown. Figure 2, a screw 513 is rotatably provided at the end of the push rod 512, and a threaded sleeve 514 threadedly connected to the screw 513 is fixedly installed on the mobile frame 2. A crossbar is fixedly connected to the top of the two push rods 512, and a screw 513 is rotatably provided on the crossbar. A top beam is fixedly installed on the top of the mobile frame 2, and a threaded sleeve 514 threadedly connected to the screw 513 is fixedly installed on the top beam. During on-site construction, when the mobile frame 2 is placed on the double-walled corrugated pipe and the arc-shaped arms 3 on both sides of the mobile frame 2 are clamped on the outside of the double-walled corrugated pipe, the screw 513 can be rotated to drive the limit plate 5 to slide out from the outside of the mobile frame 2 and push the arc-shaped arms 3 to clamp on the outside of the double-walled corrugated pipe, thereby ensuring the stability of the connection between the double-walled corrugated pipe and the mobile frame 2, thereby facilitating the pulling of the double-walled corrugated pipe in the later stage.

[0048] In some embodiments, the pulling mechanism 4 can be used as follows: Figure 1 , Figure 3 See also Figure 1 , Figure 3 The pulling mechanism 4 includes a pulling rod 41, a hooking rod 42 and a limiting member 43. The pulling rod 41 is installed on the arc frame 1, and the position of the pulling rod 41 on the arc frame 1 has the freedom to be adjusted along the axial direction of the arc frame 1; one end of the hooking rod 42 is hingedly arranged on the pulling rod 41, and an arc groove for accommodating the hooking rod 42 is arranged on the arc arm 3; the limiting member 43 is threadedly connected with the pulling rod 41, and the limiting member 43 can abut against the side wall of the arc arm 3. The pulling rod 41 is installed on the outside of the arc frame 1, and the length direction of the pulling rod 41 is arranged along the first direction, and the position of the pulling rod 41 on the arc frame 1 has the freedom to be adjusted along the first direction. The hooking rod 42 is hingedly arranged at one end of the pulling rod 41 close to the moving frame 2, and the hooking rod 42 has the freedom to swing along the pitch angle on the arc frame 1. When the moving frame 2 and the arc frame 1 are respectively installed on two double-walled corrugated pipes to be connected, the hooking rod 42 can be swung to the inside of the arc groove on the arc arm 3, thereby realizing the connection between the arc arm 3 and the arc frame 1. Then, the arc arm 3 can be driven to move toward the arc frame 1 by moving the pulling rod 41, thereby pulling the double-walled corrugated pipe to be connected to move.

[0049] Specifically, in this embodiment, a connection portion is provided protruding outward from the middle of the arc-shaped arm 3, an arc groove is located on the connection portion, and a limit member 43 is threadedly connected to the pull rod 41, the limit member 43 is a nut, and the limit member 43 is used to abut against the side of the connection portion away from the arc frame 1, so that when the pull rod 41 moves, the arc-shaped arm 3 can be pulled to move together. At the same time, during the on-site construction process, when there is a deviation in the displacement of the two arc-shaped arms 3, causing the double-walled corrugated pipe to tilt during the docking process, the position of the nut on the single pull rod 41 can be adjusted to achieve fine adjustment of the position of the single-side arc-shaped arm 3. This ensures that the two arc-shaped arms 3 can move synchronously and ensures the coaxiality between the two double-walled corrugated pipes to be docked, thereby ensuring the docking accuracy between the two double-walled corrugated pipes.

[0050] Preferably, in this embodiment, by hingedly setting the hanging rod 42 on the pulling rod 41, on the one hand, it is convenient to separately install the arc frame 1 and the movable frame 2 on two corresponding double-wall corrugated pipes, and at the same time, the relative positions of the two arc arms 3 can be fine-tuned to ensure the docking accuracy.

[0051] In some embodiments, the arc frame 1 can be used as follows Figure 1 , Figure 3 See also Figure 1 , Figure 3 The arc frame 1 is provided with a pulling assembly 44 for driving the pulling rod 41 to move in a direction away from the moving frame 2. The pulling assembly 44 includes a moving block 441, a swinging rod 442, a supporting rod 443 and an anti-reverse assembly 45. There are two moving blocks 441, two moving blocks 441 are installed on the arc frame 1 at intervals along the first direction, and the two moving blocks 441 are slidably installed on the arc frame 1 along the first direction. The pulling rod 41 is installed on the moving block 441 on the side away from the moving frame 2; one end of the swinging rod 442 is hinged on one of the moving blocks 441; one end of the supporting rod 443 is hinged on the two moving blocks 441 with the swinging rod 442, and the other end is hinged on the middle part of the swinging rod 442; the anti-reverse assembly 45 is installed between the arc frame 1 and the moving block 441, and is used to limit the moving block 441 to move in a direction close to the moving frame 2. Long grooves for installing the moving block 441 are fixedly installed on both sides of the arc frame 1, and long round through holes are arranged along the first direction in the length direction on the side walls of the long grooves. Sliding rods slidably arranged inside the long round through holes are respectively arranged at both ends of the moving block 441, so that the moving block 441 can slide on the arc frame 1.

[0052] Specifically, in this embodiment, one end of the swing rod 442 is hingedly arranged on the moving block 441 on the side close to the moving frame 2, and the swing rod 442 is tilted from bottom to top in the direction away from the moving frame 2. The support rod 443 is hingedly arranged on the moving block 441 on the side away from the moving frame 2, and the support rod 443 is hingedly connected to the middle part of the swing rod 442. The support rod 443 is tilted from bottom to top in the direction close to the moving frame 2. In addition, an anti-reverse component 45 for placing the moving block 441 in the direction close to the moving frame 2 is also installed between the arc frame 1 and the moving block 441. Through the setting of the anti-reverse component 45, the moving block 441 can only move in the direction away from the moving frame 2. During on-site construction, the operator can press the swing rod 442 downward to move the moving block 441 on the side away from the moving frame 2 in the direction away from the moving frame 2, thereby pulling the pulling rod 41 to move, thereby pulling the double-wall corrugated pipe to be docked to move. Subsequently, when the swing rod 442 swings upward, it can drive the moving block 441 close to the side of the moving frame 2 to move away from the moving frame 2, so that the pulling rod 41 can be moved by operating the support rod 443 to swing, which is easy to operate and facilitates the docking of the double-wall corrugated pipe.

[0053] In some embodiments, the anti-reverse component 45 can be used as follows: Figure 3 , Figure 4 See also Figure 3 , Figure 4 The anti-reverse assembly 45 includes a tooth plate 451, a limit plate 452 and an elastic member 453. The tooth plate 451 is fixedly mounted on the outer side of the arc frame 1, and the length direction of the tooth plate 451 is arranged along the first direction; the limit plate 452 is hingedly arranged on the side of the moving block 441 close to the moving frame 2, and the other end of the limit plate 452 is overlapped on the tooth plate 451, and the tooth plate 451 is provided with teeth for limiting the limit plate 452 to move in the direction close to the moving frame 2; the elastic member 453 is installed between the limit plate 452 and the moving block 441, and is used to push the limit plate 452 against the teeth. The tooth plates 451 are fixedly mounted on both sides of the arc frame 1, and the tooth plates 451 are fixedly mounted on the outer side of the arc frame 1. Limiting plates 452 are installed on both the upper and lower sides of the tooth plate 451. The middle part of the limiting plate 452 is hingedly arranged on the moving block 441, and the limiting plate 452 is tilted in the direction away from the tooth plate 451 and away from the moving frame 2. When the moving block 441 moves in the direction away from the moving frame 2, the contact end of the limiting plate 452 and the tooth plate 451 swings upward so that the moving block 441 can move in the direction away from the moving frame 2. When the moving block 441 moves in the direction close to the moving frame 2, the limiting plate 452 will press downward against the tooth plate 451, and at the same time, the limiting of the teeth on the tooth plate 451 can effectively prevent the moving block 441 from moving in the direction close to the moving block 441.

[0054] Specifically, in this embodiment, the elastic member 453 is a spring, both ends of which are respectively against the limit plate 452 and the moving block 441 , and the hinge axis of the limit plate 452 on the moving block 441 is located between the elastic member 453 and the tooth plate 451 .

[0055] Preferably, in this embodiment, the side surfaces of the teeth on the limiting plate 452 are inclined with chamfers that match the limiting plate 452 , so that the end of the limiting plate 452 can slide between the two teeth to play a limiting role.

[0056] Specifically, in this embodiment, when the moving block 441 is adjusted to the initial state, the limiting plate 452 can be pressed to disengage the limiting plate 452 from the tooth plate 451, thereby pushing the moving block 441 to move toward the moving frame 2, which is easy to operate and simple to use.

[0057] In some embodiments, the support rod 443 may be Figure 4 See the structure shown. Figure 4 , a mounting shaft 444 for connecting the support rod 443 is installed on the swing rod 442, and a hook body for hanging on the mounting shaft 444 is arranged at the end of the support rod 443, and the mounting shaft 444 is rotatably arranged inside the hook body. A mounting shaft 444 is installed in the middle of the swing rod 442, and the hook body on the support rod 443 can be hung on the mounting shaft 444 by adjusting the angle of the swing rod 442 and the support rod 443, so as to realize the connection between the swing rod 442 and the support rod 443. At the same time, when the two moving blocks 441 are reset, the support rod 443 can be removed from the swing rod 442, and each moving block 441 can be moved separately, so as to facilitate the adjustment of the moving block 441 to move to the initial state.

[0058] Specifically, in this embodiment, the two arc-shaped arms 3 correspond to two pull rods 41, and the two pull rods 41 are respectively connected to two swing rods 442. The two swing rods 442 can be pressed at the same time to drive the two arc-shaped arms 3 to move at the same time. When the moving direction of the double-walled corrugated pipe to be connected is inclined, the swing rod 442 on one side can be pressed to adjust the inclination angle of the double-walled corrugated pipe and align the double-walled corrugated pipe.

[0059] In some embodiments, the arc frame 1 can be used as follows Figure 1 See the structure shown. Figure 1, the top of the arc frame 1 is also provided with a crossbeam 6 for fixing to the ground, and the arc frame 1 is slidably arranged on the crossbeam 6 in the vertical direction. A crossbeam 6 is installed on the top of the arc frame 1, and the crossbeam 6 is used to overlap the top of the groove for installing the double-wall corrugated pipe. During on-site construction, the crossbeam 6 is first placed on the ground, and then the arc frame 1 is lowered to the double-wall corrugated pipe, and when the arc frame 1 is fixed to the double-wall corrugated pipe, the crossbeam 6 can be fixed to the ground, thereby enhancing the stability of the position of the arc frame 1. During on-site construction, the arc frame 1 can be installed on the double-wall corrugated pipe that has been installed in place, and the mobile frame 2 can be installed on the double-wall corrugated pipe that needs to be newly installed.
