Description

Technical Field

[0001] The present application relates to the technical field of drainage pipe docking installation, and in particular to an urban drainage pipe docking maintenance auxiliary device. Background Art

[0002] Drainage pipes refer to the system of pipes and ancillary facilities that collect and discharge sewage, wastewater, and rainwater. These include main pipes, branch pipes, and pipes leading to treatment plants. Regardless of whether they are located on streets or elsewhere, any pipe that serves a drainage function should be counted as a drainage pipe. With the development of cities and the rapid development of drainage projects, the use of urban drainage pipes has become increasingly common. During the installation process, auxiliary docking devices are often required to assist workers in docking and installing the pipes.

[0003] For example, in the existing Chinese patent with publication number CN214723843U, a municipal drainage pipe bellows electric hydraulic connection auxiliary frame is disclosed, which includes a main frame, a sliding frame and a driving device. The main frame is a square frame structure with an internal movable space so that the sliding frame and the driving device can be installed in the main frame; the sliding frame is arranged inside the main frame and is slidably connected to the main frame, and the sliding frame slides along the setting direction of the main frame; the driving device is arranged between the main frame and the sliding frame, and the driving device is used to drive the sliding frame to slide in the main frame. Through the above-mentioned existing technology, when the bellows are docked, the bellows are clamped on the main frame and the sliding frame respectively, and the ends of the two bellows are clamped in the first clamping ring and the second clamping ring respectively. Through the driving device, the sliding frame is driven to slide and translate from the first side of the main frame to the second side of the sliding frame, driving one of the bellows to dock with the other bellows clamped on the main frame, thereby completing automated docking.

[0004] However, the above-mentioned prior art has the following technical defects:

[0005] 1. The first clamping ring and the second clamping ring in the above-mentioned prior art are both semicircular in design, and the pipe is driven by respectively clamping the first clamping ring and the second clamping ring on the upper side of two different pipes; in the actual pipeline laying process, the lower side of the pipe is usually in contact with the ground, and the first clamping ring and the second clamping ring are only semicircular rings clamped on the upper side of the pipe, and the force points are uneven. When the pipe is driven, the lower side of the pipe collides with the ground, which will generate a large friction force, easily causing damage to the pipe, and problems such as gaps and cracks at the docking end, and thus making it impossible to achieve a good docking.

[0006] Second, since pipelines are usually laid underground, dust, stones and other debris are very likely to be present at the joints of the pipelines during the process of driving the pipelines to connect. If they are not cleaned during the installation, gaps will exist at the joints of the two pipelines, affecting the sealing and normal use of the pipelines, reducing the service life of the pipelines and increasing the maintenance costs of the pipelines.

[0007] Based on this, on the basis of the existing municipal drainage pipe bellows electric hydraulic connection auxiliary frame, in order to overcome the above technical defects, there is still room for improvement. Summary of the Invention

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. First, turn the rocker to adjust the synchronous sliding adjustment spacing of the two clamping mechanisms, and adjust the two clamping mechanisms to the upper position of the two drainage pipes close to the pipe interface. By turning the adjustment wheel in the adjustment assembly, the rectangular telescopic column can be driven to extend downward, which will synchronously drive the clamping assembly to move downward. After the movement drops to a certain distance, the round rod in the driver will conflict with the drainage pipe to drive the arc-shaped claw rod to clamp on the outer wall of the drainage pipe.

[0023] 2. Then, the rocker is rotated again to continue to control the reduction of the distance between the two clamping mechanisms. The arc-shaped claw rod can be used to drive the two drainage pipes to be brought closer to each other to achieve the docking effect. In the process of controlling the reduction of the distance between the two clamping mechanisms to dock the pipes, the cleaning mechanism operates. With the cooperation of the long rack and the transmission gear, the bidirectional screw can be driven to rotate to continuously transport the gas in the arc-shaped long box to the arc-shaped exhaust pipe, and then discharged through the exhaust valve distributed on the arc-shaped exhaust pipe, thereby forming a flowing airflow on the outer wall of the drainage pipe. The continuously ejected gas can clean the outer wall of the docking interface at the smaller diameter end of the drainage pipe. At the same time, as the gas flows, the dust, stones and other impurities in the inner wall of the docking interface at the larger diameter end of the drainage pipe can continue to be cleaned.

[0024] 3. When the drainage pipe is connected and the gripping effect of the arc-shaped claw rod on the drainage pipe needs to be released, the releasing round rod can be rotated ninety degrees to drive the round wheel protrusion to align with the convex sliding hole. At this time, the round push rod is no longer restricted by the limiting groove and can slide in the driving rack. Under the action of the reset spring, the driving rack can slide downward for a distance to retract the round push rod into the driving rack. When the driving rack slides downward, it can drive the two arc-shaped claw rods to expand outward to initially release the gripping effect on the drainage pipe, and then cooperate with the rotation of the adjusting wheel to drive the rectangular telescopic column to move upward and reset. As the rectangular telescopic column continues to rise, the driving rack is gradually reset under the action of the reset spring and drives the arc-shaped claw rod to fully expand and reset, thereby completely releasing the gripping effect on the drainage pipe.

A dovetail slot 612 for the sliding installation of the dovetail long strip 74 is provided on the clamping seat 61. When the driving rack 71 is forced to slide upward, the arc-shaped claw rod 62 can be driven to rotate downward under the action of the two control gears 64, that is, the grasping effect is achieved. When the driving rack 71 is forced to slide downward, the arc-shaped claw rod 62 can be driven to rotate upward under the action of the two control gears 64, that is, the effect of releasing the grasping is achieved.

[0051] When the cam 72 is in the closed position, the locking cam 72 is in the closed position, and the locking cam 72 is in the closed position, so that the cam 72 can slide smoothly, and the cam 72 can slide smoothly, and the cam 72 can slide smoothly. When the lower end of the circular rod 73 is subjected to a force, that is, when the lower end of the circular rod 73 contacts the outer wall of the drainage pipe 11, the circular rod 73 is restricted and cannot slide upward, so it can push the driving rack 71 to rise together, and under the action of the control gear 64, it drives the two arc-shaped claw rods 62 to rotate downward to grab and fix the drainage pipe 11; when an external force drives the circular wheel protrusion 75 to rotate it ninety degrees, the circular wheel protrusion 75 will align with the convex sliding hole 713. Since the circular hole 712, the limiting groove 711 and the convex sliding hole 713 are interconnected, when the lower end of the circular rod 73 is subjected to a force, it can extend into the driving rack 71. The release member 8 is provided on the driving rack 71 and can drive the circular wheel protrusion 75, which can release the gripping force of the arc-shaped claw rod 62.

[0052] Reference Figure 10 and Figure 11The figure shows the structure of the release member 8 in this embodiment. The release member 8 includes a limit seat 81, a return spring 82, a magnet 83 and a release rod 84; the limit seat 81 is fixedly installed at the lower end of the dovetail strip 74, one end of the return spring 82 is fixedly installed on the limit seat 81, and the other end extends upward into the clamping seat 61, and the return spring 82 always has a driving force to push the limit seat 81 downward, that is, the driving force to push the drive rack 71 downward; the clamping seat 61 is provided with a spring receiving groove 613 for the return spring 82 to be inserted and installed, the magnet 83 is arranged in the limit groove 711, and the release rod 84 is inserted in the convex sliding hole 713 and fixedly connected to the round wheel protrusion 75. When the docking of the drainage pipe 11 is completed and the gripping and fixing force of the arc-shaped claw rod 62 on the drainage pipe 11 needs to be released, the driving release rod 84 is rotated ninety degrees, that is, the driving wheel protrusion 75 and the round abutment rod 73 are rotated ninety degrees. At this time, the wheel protrusion 75 will be aligned with the convex sliding hole 713, and the wheel protrusion 75 and the round abutment rod 73 can slide freely in the driving rack 71. Under the action of the reset spring 82, the driving rack 71 slides downward for a distance, so that the lower end of the driving rack 71 contacts the outer wall of the drainage pipe 11, and the round abutment rod 73 will be retracted into the driving rack 71.

[0053] The driving rack 71 slides downward for a distance, initially driving the arc-shaped claw rods 62 to rotate and expand outward, that is, the arc-shaped claw rods 62 no longer clamp the drainage pipe 11, and cooperates with the rotation of the adjustment wheel 57 to drive the rectangular telescopic column 32 to rise. The return spring 82 continuously drives the driving rack 71 downward until it returns to its initial position. When the driving rack 71 returns to its initial position, it simultaneously drives the two arc-shaped claw rods 62 to expand outward and return to their initial positions, thereby releasing the arc-shaped claw rods 62 from gripping the drainage pipe 11. At the same time, as the rectangular telescopic column 32 rises away from the drainage pipe 11, the round wheel protrusion 75, the round abutment rod 73, and the release rod 84 slide downward and return to their original position under the action of gravity. The round wheel protrusion 75 returns to the limit groove 711. Since the protrusion of the round wheel protrusion 75 is made of metal, the magnet block 83 drives the round wheel protrusion 75 to rotate 90 degrees to return to its original position. That is, the limit groove 711 once again forms a restriction on the round abutment rod 73 through the round wheel protrusion 75 to return to its original state.

[0054] Reference Figure 12As shown, in the process of laying the drainage pipe 11 to laying the pipe groove 101, the docking end of the drainage pipe 11 is prone to fall and there are dust, stones and other debris. If it is not cleaned, it will affect the docking sealing of the drainage pipe 11 and affect normal use. The cleaning mechanism 4 includes an arc-shaped long box 41, a one-way air inlet valve 42, an upper one-way air outlet valve 43, a lower one-way air outlet valve 44, an arc-shaped exhaust pipe 45, an exhaust valve 46, a connecting valve 47, a telescopic hose 48, a telescopic long tube 49 and a transmission component 9; the arc-shaped long box 41 is fixedly mounted on the outside of the rectangular long column 31 The two one-way air inlet valves 42 are respectively arranged at the upper and lower ends of the arc-shaped long box 41, the upper one-way air outlet valve 43 and the lower one-way air outlet valve 44 are symmetrically installed on the outer wall of the arc-shaped long box 41, and the two arc-shaped exhaust pipes 45 are respectively fixedly installed on the outside of the two arc-shaped claw rods 62. In this embodiment, preferably, nineteen exhaust valves 46 are equidistantly arranged on the arc-shaped exhaust pipe 45, and the connecting valve 47 is provided on the arc-shaped exhaust pipe 45. One end of the telescopic hose 48 and the telescopic long tube 49 are connected to the connecting valve 47, and the other end is connected to the upper one-way air outlet valve 43 and the lower one-way air outlet valve 44 respectively.

[0055] The transmission assembly 9 is arranged on the arc-shaped long box 41 and the stabilization auxiliary frame 20, and is used to compress the air in the arc-shaped long box 41 and simultaneously form a negative pressure, and then suck the outside air into the arc-shaped long box 41 through the one-way air inlet valve 42, and the squeezed air will be discharged into the arc-shaped exhaust pipe 45 through the upper one-way air outlet valve 43 and the lower one-way air outlet valve 44, and finally ejected through multiple exhaust valves 46 to form a flowing airflow on the outer surface of the drainage pipe 11, and the air is blown toward the drainage pipe 11 with a larger diameter at the docking end. During the air blowing process, the outer wall of the drainage pipe 11 with a smaller diameter at the docking end can be cleaned, and the continued flow of gas can simultaneously clean the dust, stones and other debris in the inner wall of the drainage pipe 11 with a larger diameter at the docking end, so that the inner wall and the outer wall of the docking end of the two drainage pipes 11 are in a clean state, respectively, to better assist the operator in docking the drainage pipe 11.

[0056] Reference Figure 12 and Figure 13As shown, the structure of the transmission assembly 9 in this embodiment is schematically shown. The transmission assembly 9 includes an elongated rack 91, a rubber block 92, a bidirectional screw 93 and a transmission gear 94; one end of the elongated rack 91 is fixedly mounted on the rectangular middle block 21, and the other end passes through the travel slider 23 and is fixedly connected to the inner wall of the stabilizing auxiliary frame 20. A travel hole 233 is provided on the travel slider 23 for the elongated rack 91 to penetrate. The rubber block 92 is slidably set in the arc-shaped long box 41, and one end of the bidirectional screw 93 is rotatably set in the inner cavity of the arc-shaped long box 41. The bottom, the other end penetrates the rubber block 92 and the arc-shaped long box 41 and extends upward. The rubber block 92 is penetrated by a screw rod through-hole 921 that is adapted to and penetrates the bidirectional screw rod 93. The bidirectional screw rod 93 rotates under the force and cooperates with the screw rod through-hole 921 to drive the rubber block 92 to slide back and forth in the arc-shaped long box 41; the arc-shaped long box 41 is provided with an extension hole 411 for the bidirectional screw rod 93 to penetrate and extend out. The transmission gear 94 is fixedly mounted on the protruding end of the bidirectional screw rod 93 and meshes with the long rack 91.

[0057] After the clamping assembly 6 grabs and fixes the drainage pipe 11, the rocker 29 is rotated to drive the travel slider 23 and the clamping mechanism 3 installed under the travel slider 23 to slide, driving the travel slider 23 to reduce the distance between the two travel sliders and grab the fixed drainage pipe 11 through the clamping mechanism 3 to achieve the purpose of driving the two drainage pipes 11 to move closer to each other for docking; and in the process of sliding of the travel slider 23, under the action of the long rack 91 and the transmission gear 94, the bidirectional screw rod 93 can be driven to rotate, that is, the rubber block 92 is automatically driven to slide back and forth up and down in the arc-shaped long box 41 to squeeze the air in the arc-shaped long box 41 to discharge, while forming a negative pressure in the arc-shaped long box 41, and continuously sucking the outside air into the arc-shaped long box 41 through the two one-way air inlet valves 42, so as to continuously discharge the air to the arc exhaust pipe 45, and discharge the gas through multiple exhaust valves 46 to achieve the effect of cleaning the docking point of the two drainage pipes 11.

[0058] The implementation principle of this embodiment is:

[0059] (1) Adjusting the spacing: First, place the stabilizing auxiliary frame 20 above the joint of the two sections of drainage pipes 11 that need to be connected, and turn the rocker 29 to drive the travel slider 23 to slide, so as to adjust it to a position suitable for the clamping assembly 6 to grab and fix the drainage pipe 11.

[0060] (2) Grasping and fixing: After adjusting the position of the travel slider 23, rotate the adjusting wheel 57 to synchronously drive the two rectangular telescopic columns 32 to drive the clamping assembly 6 to move downward. After the round abutment rod 73 contacts the outer wall of the drainage pipe 11, the two arc-shaped claw rods 62 can be driven to rotate downward to achieve the effect of grasping and fixing the drainage pipe 11.

[0061] (3) Docking and cleaning: After the two sections of the drainage pipes 11 are grasped and fixed, the rocker 29 is rotated again to continue to reduce the distance between the two sliding blocks 23 to drive the two drainage pipes 11 to move closer to each other for docking; in this process, through the cooperation of the long rack 91 and the transmission gear 94, the bidirectional screw rod 93 is driven to rotate and drive the rubber block 92 to slide back and forth in the arc-shaped long box 41, so as to continuously discharge air into the arc-shaped exhaust pipe 45, and the gas is discharged through multiple exhaust valves 46 to achieve the effect of cleaning the docking point of the two drainage pipes 11.

[0062] (4) Release the fixation: After the drainage pipe 11 is connected, the release rod 84 is rotated to drive the round wheel protrusion 75 and the round support rod 73 to rotate ninety degrees, so that the round wheel protrusion 75 is aligned with the convex sliding hole 713. Under the drive of the reset spring 82, the arc claw rod 62 is initially released to release the gripping force of the drainage pipe 11, and then the rectangular telescopic column 32 is driven to rise in conjunction with the rotation of the adjustment wheel 57. The reset spring 82 continuously drives the driving rack 71 to slide down until it returns to its initial position. When the driving rack 71 returns to its initial position, it simultaneously drives the two arc claw rods 62 to expand outward and return to their initial position, thereby completely releasing the gripping effect of the arc claw rod 62 on the drainage pipe 11.

[0063] The embodiments of this specific implementation method are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
