Description

Technical Field

[0001] This invention belongs to the field of municipal water supply and drainage pipeline construction technology, specifically involving a hoisting device for auxiliary installation of rubber rings in reinforced concrete drainage pipes. Background Technology

[0002] The installation of reinforced concrete drainage pipes is a core process in the construction of municipal drainage networks. Before construction, surveying and setting out, excavation of the foundation pit, and leveling and compaction of the base are completed, along with proper foundation bedding. Upon arrival, pipe materials must be inspected for appearance, strength, and dimensions, and damaged or cracked components are removed. A crane is used in conjunction with manual labor to lower the pipes, ensuring precise alignment according to the design slope and axis, and controlling the elevation and centerline deviation of the pipe sections. Pipe joints are sealed using flexible joints filled with sealing material to prevent leakage. During installation, the pipe slope and straightness are continuously corrected to ensure smooth drainage without backflow. After the pipes are in place, joint curing, layered backfilling and compaction of the foundation pit are carried out, and a water tightness test is conducted simultaneously to verify the pipe's seepage prevention and drainage performance. The entire process must strictly adhere to construction specifications to ensure the drainage pipe structure is stable, has good sealing performance, and meets the long-term discharge requirements of municipal stormwater and sewage.

[0003] Currently, the installation of reinforced concrete drainage pipes generally adopts the method of direct lifting by crane and manual assistance in positioning. The rubber ring is manually inserted into the groove at the end of the pipe, and then the pipe is connected and tightened to complete the sealing installation. This method has the following disadvantages: the rubber ring is prone to misalignment, twisting, and falling off; the lifting and installation are not synchronized; the pipe connection accuracy is poor; the safety risk is high; and the compression of the rubber ring cannot be controlled. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a hoisting device for auxiliary installation of rubber rings in reinforced concrete drainage pipes.

[0005] The technical solution adopted to solve the above technical problems is: to provide a hoisting device for auxiliary installation of rubber rings of reinforced concrete drainage pipes in this embodiment, including a hoisting drive device, a steel cable assembly is provided on the hoisting drive device, a steel cable connecting assembly is installed at one end of the steel cable assembly, and a rotary joint is fixedly connected to the bottom of the steel cable connecting assembly.

[0006] The bottom of the rotary joint is equipped with a mounting bracket opening and closing mechanism. The rotary joint is used to rotate and fine-tune the mounting bracket opening and closing mechanism. A pressing connection mechanism is slidably connected to one side of the mounting bracket opening and closing mechanism, and a guide transmission mechanism is fixedly connected to one side of the pressing connection mechanism.

[0007] The outer wall of the guide transmission mechanism is slidably connected to a collar mechanism, and a rubber ring is fitted onto the outer wall of the collar mechanism. The collar mechanism is used for pre-installing the rubber ring. The interior of the mounting opening and closing mechanism is provided with a concrete pipe, and a concrete support strip is provided at the bottom of the concrete pipe. The concrete support strip is used for supporting and positioning the concrete pipe.

[0008] Furthermore, the mounting bracket opening and closing mechanism includes a U-shaped support plate fixedly connected to the bottom of the rotary joint. A fixed shaft is fixedly connected between the two sides of the inner wall of the U-shaped support plate. Two opening and closing claws are rotatably connected to the fixed shaft. A hydraulic control component is installed at the bottom center of the U-shaped support plate. Hydraulic rods are fixedly and rotatably connected to both the front and rear sides of the bottom center of the U-shaped support plate. Multiple anti-slip pads are fixedly connected to both sides of the inner wall of the two opening and closing claws.

[0009] The above technical solution controls the extension and retraction of two hydraulic rods through a hydraulic control component, thereby pulling or pushing two opening and closing claws to rotate around a fixed shaft, realizing the opening and closing of the two opening and closing claws. At the same time, multiple anti-slip pads can prevent the concrete pipe from shifting during clamping, increasing friction while also preventing damage to the concrete pipe from hard contact.

[0010] Furthermore, a limiting sleeve corresponding to the pressing connection mechanism is fixedly connected to one side of the U-shaped support plate, and a through hole corresponding to the pressing connection mechanism is opened therein, and the output end of the hydraulic rod is rotatably connected to the opening and closing claw.

[0011] The above technical solution allows for the limiting installation of the clamping connection mechanism via a limiting sleeve. When the clamping connection mechanism and the guiding transmission mechanism are no longer needed, they can be disassembled.

[0012] Furthermore, the clamping connection mechanism includes an L-shaped connecting frame, with multiple limiting pins installed on one side of the L-shaped connecting frame, and a connecting circular plate fixedly connected to the bottom of the other side of the L-shaped connecting frame. A fixed circular sleeve is fixedly connected to the outer wall of the connecting circular plate, and multiple pressure springs are provided on the outer wall of the fixed circular sleeve. A movable circular sleeve is fixedly connected between the other ends of the multiple pressure springs, and an integrated compression ring is fixedly connected to one side of the movable circular sleeve.

[0013] Through the above technical solution, the overall guiding and transmitting mechanism is connected by a clamping connection mechanism. At the same time, when the concrete pipe is pushed in the future, the hoisting drive device drives the mounting opening and closing mechanism, the clamping connection mechanism and the guiding and transmitting mechanism to move. At this time, the clamping connection mechanism and the guiding and transmitting mechanism continue to go deeper until the integrated extrusion ring on one side of the movable sleeve begins to squeeze the rubber ring and compress multiple pressure springs. Under the thrust generated by the multiple pressure springs, the rubber ring is squeezed to the outer wall of the top of the concrete pipe, thus achieving precise installation of the rubber ring.

[0014] Furthermore, the outer walls of the fixed sleeve and the movable sleeve are respectively fixedly connected with a plurality of protective sleeves and sliding ears corresponding to the pressure springs. The movable sleeve is sleeved on the outer wall of the fixed sleeve, and the cross-section of one side of the integrated extrusion ring is a beveled structure.

[0015] Through the above technical solution, the protective sleeve can protect the pressure spring, the sliding ear and the movable round sleeve are fixedly connected to transmit the elastic force of multiple pressure springs, and the inclined structure of the integrated extrusion ring is used to fit the inclined surface of the rubber ring, thereby achieving precise installation.

[0016] Furthermore, the guiding and transmitting mechanism includes an extension sleeve, the other end of which is fixedly connected to a hollow guide cone. The inner wall of the hollow guide cone is fixedly connected to a plurality of built-in mounting shells. The inner walls of the plurality of built-in mounting shells are all fixedly connected to positioning springs. The other ends of the plurality of positioning springs are all fixedly connected to sliding limiting shells. The outer walls of the plurality of sliding limiting shells are all fixedly connected to roller assemblies.

[0017] Through the above technical solution, when hoisting concrete pipes, the moving guide transmission mechanism inserts the hollow guide cone into the interior of the concrete pipe through its arc surface. Precise positioning is achieved under the arc surface structure. As it goes deeper, multiple roller assemblies will contact the inner wall of the concrete pipe and begin to squeeze the roller assemblies, thereby compressing the positioning springs. After all three roller assemblies have entered the interior of the concrete pipe, under the action of multiple positioning springs, when connecting two concrete pipes in the subsequent process, the hollow guide cone in the guide transmission mechanism extends from the inner wall of one concrete pipe into the other concrete pipe, thereby achieving precise positioning.

[0018] Furthermore, the hollow guide cone has multiple through holes corresponding to the roller assembly, and the number of roller assemblies and through holes is three.

[0019] Through the above technical solution, the three roller assemblies can achieve precise positioning of the hollow guide cone, so that the center line of the hollow guide cone coincides with the center line of the concrete pipe.

[0020] Furthermore, the ring mechanism includes a sliding bracket slidably connected to the outer wall of the extension sleeve, and a guide sleeve is fixedly connected to the outer wall of the sliding bracket, one side of which has an arc-shaped structure.

[0021] With the above technical solution, when hoisting the concrete pipe, the ferrule mechanism is slid to the side close to the hollow guide cone, and then the rubber ring is taken out and first fitted onto one side of the ferrule mechanism. Then, the rubber ring is smoothly fitted onto the outer wall of the guide sleeve by the arc surface of the guide sleeve. Subsequently, the ferrule mechanism is slid to the other side of the extension sleeve. When installing the rubber ring later, the rubber ring can be installed by squeezing the rubber ring with an integrated extrusion ring.

[0022] Furthermore, the top of the concrete support strip has a concave arc-shaped structure.

[0023] With the above technical solution, during construction, the foundation pit is dug, and concrete support strips are placed at equal intervals inside the foundation pit according to the length of the concrete pipe, and the concrete support strips are embedded in the bottom of the foundation pit. The concave structure can fit the surface of the concrete pipe better.

[0024] The beneficial effects of the present invention are as follows: (1) The present invention, through the design of the pressing connection mechanism and the ring mechanism, realizes the prefabrication and installation of the rubber ring, and automatically realizes the installation and fixation of the rubber ring during the subsequent hoisting and fitting of the concrete pipe. The present invention also realizes the precise push-in installation by designing the guide sleeve, multiple pressure springs, movable sleeve and integrated extrusion ring to squeeze the rubber ring, thus ensuring the sealing quality; (2) The present invention, through the design of the pressing connection mechanism and the guide transmission mechanism, moves the guide transmission mechanism when hoisting the concrete pipe. The hollow guide cone is inserted into the interior of the concrete pipe through the arc surface, and precise positioning is achieved under the arc surface structure. As it goes deeper, multiple roller components will contact the inner wall of the concrete pipe and begin to squeeze the roller components and then compress the positioning spring. Until all three roller components have entered the interior of the concrete pipe, under the action of multiple positioning springs, when fitting two concrete pipes in the subsequent process, the hollow guide cone in the guide transmission mechanism extends from the inner wall of one concrete pipe into the other concrete pipe, thus realizing precise positioning.

[0037] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0038] like Figures 1-3 As shown, the lifting device for installing rubber rings of reinforced concrete drainage pipes in this embodiment includes a lifting drive device 1, a steel cable assembly 2 is provided on the lifting drive device 1, a steel cable connecting assembly 3 is installed at one end of the steel cable assembly 2, and a rotary joint 4 is fixedly connected to the bottom of the steel cable connecting assembly 3.

[0039] like Figures 1-5As shown, a mounting bracket opening and closing mechanism 5 is installed at the bottom of the rotary joint 4. The rotary joint 4 is used to rotate and fine-tune the mounting bracket opening and closing mechanism 5. The mounting bracket opening and closing mechanism 5 includes a U-shaped support plate 501 fixedly connected to the bottom of the rotary joint 4. A fixed shaft 502 is fixedly connected between the two sides of the inner wall of the U-shaped support plate 501. Two opening and closing grippers 503 are rotatably connected to the fixed shaft 502. A hydraulic control component 504 is installed at the bottom center of the U-shaped support plate 501. Hydraulic rods 505 are fixedly and rotatably connected to the front and rear sides of the bottom center of the U-shaped support plate 501. Multiple anti-slip pads 506 are fixedly connected to the inner walls of the two opening and closing grippers 503. The hydraulic control component 504 controls the two hydraulic rods 505. The telescopic mechanism pulls or pushes the two opening and closing claws 503 to rotate around the fixed shaft 502, thereby opening and closing the two opening and closing claws 503. At the same time, multiple anti-slip pads 506 can prevent the concrete pipe 10 from shifting during clamping, improve friction, and avoid damage to the concrete pipe 10 from hard contact. A limiting sleeve corresponding to the clamping connection mechanism 6 is fixedly connected to one side of the U-shaped support plate 501, and a through hole corresponding to the clamping connection mechanism 6 is opened. The output end of the hydraulic rod 505 is rotatably connected to the opening and closing claws 503. The limiting sleeve can realize the limiting installation of the clamping connection mechanism 6. When the clamping connection mechanism 6 and the guide transmission mechanism 7 are not needed, they can be disassembled.

[0040] like Figures 1-9As shown, a clamping connection mechanism 6 is slidably connected to one side of the mounting opening and closing mechanism 5. The clamping connection mechanism 6 includes an L-shaped connecting frame 601. Multiple limit pins 602 are installed on one side of the L-shaped connecting frame 601. A connecting circular plate 603 is fixedly connected to the bottom of the other side of the L-shaped connecting frame 601. A fixing circular sleeve 604 is fixedly connected to the outer wall of the connecting circular plate 603. Multiple pressure springs 605 are provided on the outer wall of the fixing circular sleeve 604. A movable circular sleeve 606 is fixedly connected between the other ends of the multiple pressure springs 605. An integrated compression ring 607 is fixedly connected to one side of the movable circular sleeve 606. The clamping connection mechanism 6 connects to the overall guide transmission mechanism 7. At the same time, when the concrete pipe 10 is subsequently pushed, the mounting opening and closing mechanism 5, the clamping connection mechanism 6, and the guide transmission mechanism 7 are moved by the hoisting drive device 1. At this time, the clamping connection mechanism... The guide transmission mechanism 6 and 7 continue to penetrate until the integrated compression ring 607 on one side of the movable sleeve 606 begins to compress the rubber ring 9 and compress multiple pressure springs 605. Under the thrust generated by the multiple pressure springs 605, the rubber ring 9 is squeezed to the outer wall of the top of the concrete pipe 10, achieving precise installation of the rubber ring 9. The outer walls of the fixed sleeve 604 and the movable sleeve 606 are respectively fixedly connected with multiple protective sleeves and sliding ears corresponding to the pressure springs 605. The movable sleeve 606 is fitted onto the outer wall of the fixed sleeve 604. The cross-section of one side of the integrated compression ring 607 is a beveled structure. The protective sleeve can protect the pressure springs 605. The sliding ear and the movable sleeve 606 are fixedly connected to transmit the elastic force of the multiple pressure springs 605. The beveled structure of the integrated compression ring 607 is used to fit the bevel of the rubber ring 9, thereby achieving precise installation.

[0041] like Figures 1-10As shown, a guide transmission mechanism 7 is fixedly connected to one side of the clamping connection mechanism 6. The guide transmission mechanism 7 includes an extension sleeve 701, and a hollow guide cone 702 is fixedly connected to the other end of the extension sleeve 701. Multiple built-in mounting shells 703 are fixedly connected to the inner wall of the hollow guide cone 702. Positioning springs 704 are fixedly connected to the inner walls of the multiple built-in mounting shells 703. Sliding limit shells 705 are fixedly connected to the other ends of the multiple positioning springs 704. Roller assemblies 706 are fixedly connected to the outer walls of the multiple sliding limit shells 705. When hoisting the concrete pipe 10, the guide transmission mechanism 7 is moved and inserted into the interior of the concrete pipe 10 through the arc surface of the hollow guide cone 702. Precise positioning is achieved under the arc surface structure. As it goes deeper, multiple roller assemblies 706... The roller assembly 706 will contact the inner wall of the concrete pipe 10 and begin to squeeze the roller assembly 706, thereby compressing the positioning spring 704. After all three roller assemblies 706 have entered the interior of the concrete pipe 10, under the action of multiple positioning springs 704, when two concrete pipes 10 are subsequently connected, the hollow guide cone 702 in the guide transmission mechanism 7 extends from the inner wall of one concrete pipe 10 into another concrete pipe 10, thereby achieving precise positioning. The hollow guide cone 702 has multiple through holes corresponding to the roller assembly 706, and the number of roller assemblies 706 and through holes is three. The three roller assemblies 706 can achieve precise positioning of the hollow guide cone 702, so that the center line of the hollow guide cone 702 coincides with the center line of the concrete pipe 10.

[0042] like Figures 1-11 As shown, a collar mechanism 8 is slidably connected to the outer wall of the guide transmission mechanism 7. The collar mechanism 8 includes a sliding bracket 81 slidably connected to the outer wall of the extension sleeve 701. A guide sleeve 82 is fixedly connected to the outer wall of the sliding bracket 81. One side of the guide sleeve 82 has an arc-shaped structure. When hoisting the concrete pipe 10, the collar mechanism 8 is slid to the side close to the hollow guide cone 702. Then, the rubber ring 9 is taken out and first fitted onto one side of the collar mechanism 8. Then, the rubber ring 9 is smoothly fitted onto the outer wall of the guide sleeve 82 through the arc surface of the guide sleeve 82. Subsequently, the collar mechanism 8 is slid to the other side of the extension sleeve 701. When installing the rubber ring 9 later, the rubber ring 9 is then... Installation can be achieved by extruding the rubber ring 9 through the integrated extrusion ring 607. The outer wall of the ring mechanism 8 is fitted with the rubber ring 9. The ring mechanism 8 is used for pre-installation of the rubber ring 9. The inside of the mounting opening and closing mechanism 5 is equipped with a concrete pipe 10. The bottom of the concrete pipe 10 is equipped with a concrete support strip 11. The concrete support strip 11 is used to support and position the concrete pipe 10. The top of the concrete support strip 11 is a concave arc structure. During construction, the foundation pit is dug, and the concrete support strips 11 are evenly spaced inside the foundation pit according to the length of the concrete pipe 10, so that the concrete support strips 11 are embedded in the bottom of the foundation pit. The concave structure can fit the surface of the concrete pipe 10 more closely.

[0043] The working principle of this embodiment is as follows: During construction, a foundation pit is dug, and concrete support strips 11 are placed at equal intervals inside the foundation pit according to the length of the concrete pipe 10. The hoisting drive device 1 moves to the top of the foundation pit and lifts the concrete pipe 10 placed on the side. During the hoisting process, the hoisting drive device 1 rotates to the side, and the steel cable assembly 2 releases the steel cable connection assembly 3, the rotary joint 4 and the mounting opening and closing mechanism 5 to descend. At the same time, the hydraulic control assembly 504 controls the two hydraulic rods 505 to start retracting, thereby pulling the two opening and closing claws 503 to rotate around the fixed shaft 502 to open. After reaching the front end of the concrete pipe 10, the collar mechanism 8 is slid to the side close to the hollow guide cone 702. Then, the rubber ring 9 is taken out and first fitted onto one side of the collar mechanism 8. Then, the rubber ring 9 is flatly fitted onto the outer wall of the guide sleeve 82 through the arc surface of the guide sleeve 82. Then, the collar mechanism 8 is slid to the other side of the extension sleeve 701.

[0044] The moving guide transmission mechanism 7 inserts into the interior of the concrete pipe 10 through the arc surface of the hollow guide cone 702. Precise positioning is achieved under the arc surface structure. As multiple roller assemblies 706 extend, they contact the inner wall of the concrete pipe 10 and begin to compress the roller assemblies 706, thereby compressing the positioning springs 704. Once all three roller assemblies 706 are inside the concrete pipe 10, positioning is achieved under the action of the multiple positioning springs 704, and the mechanism continues to penetrate to the appropriate position. The hydraulic control component 504 controls two hydraulic rods 505 to extend, which in turn pushes two opening and closing claws 503 to close, tightly gripping the concrete pipe 10. Driven by the steel cable assembly 2, the concrete pipe 10 is lifted, then rotated to directly above the pit before descending, precisely placing the concrete pipe 10 on the concrete support bar 11. Simultaneously, the tail end of the concrete pipe 10 is fitted onto the top end of another concrete pipe 10. Then, the two opening and closing claws 503 open, allowing the mechanism to proceed. The hoisting drive device 1 drives the mounting frame opening and closing mechanism 5, the pressing and connecting mechanism 6, and the guiding and transmitting mechanism 7 to move. At this time, the pressing and connecting mechanism 6 and the guiding and transmitting mechanism 7 continue to move deeper until the integrated extrusion ring 607 on one side of the movable circular sleeve 606 begins to extrude the rubber ring 9 and compress multiple pressure springs 605. Under the thrust generated by the multiple pressure springs 605, the rubber ring 9 is extruded to the outer wall of the top of the concrete pipe 10, achieving precise installation of the rubber ring 9. At the same time, when the connecting circular plate 603 is extruded to the sliding bracket 81, the concrete pipe 10 begins to slide a small distance on the concrete support strip 11 through the sliding bracket 81, thereby enabling the concrete pipe 10 to be precisely extruded and connected to the previous concrete pipe 10. During the process of the two concrete pipes 10 being connected, the hollow guide cone 702 in the guiding and transmitting mechanism 7 extends from the inner wall of one concrete pipe 10 into the other concrete pipe 10, thereby achieving precise positioning.

[0045] Similarly, by repeating the above steps, the installation of concrete pipe 10 can be continuously achieved.

[0046] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
