Description

Technical Field

[0001] This utility model belongs to the field of pipeline laying, specifically relating to an auxiliary device for water supply and drainage construction. Background Technology

[0002] During drainage construction, pipe laying is required first. Since water supply and drainage pipes are generally heavy, a crane is needed to move them to the pipe pit during laying. The existing method is to use steel ropes to tie the pipes, then lift them for transport, and finally remove the steel ropes. Although this method can move the water supply and drainage pipes to facilitate later pipe laying, the steel ropes used to tie and fix the pipes before transport and the need to manually untie them when they reach the vicinity of the pit are time-consuming, labor-intensive, and reduce the labor intensity and efficiency of workers. Moreover, the steel ropes are prone to slipping on the pipes and may cause tilting when the pipes are lifted, posing a certain danger.

[0003] Therefore, an auxiliary device for laying underground water supply and drainage pipelines (application number: CN202421212127.5) has been proposed in the prior art. Although the auxiliary device in the above patent can stably clamp the pipeline and cooperate with equipment such as cranes or hoists to lift and transport the pipeline, when the pipeline is assembled, since the clamping plate clamps and fixes the pipeline, it is impossible to manually push the pipeline to move along the pipeline axis between the clamping plates. Therefore, when the two pipelines are brought close together for docking, there are mainly two methods: one is to lift the pipeline close to the other pipeline with a crane, but it is not easy to accurately control the displacement of the pipeline being lifted and transported by the crane, which can easily cause excessive collision between the two pipelines; the other method is to lift the pipeline to the required position, put the pipeline down, and then manually move the two pipelines close together for docking. However, since the pipeline is heavy, it is difficult to manually move and dock. Therefore, the prior art has the problem of not being able to lift the pipeline and accurately dock it. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an auxiliary equipment for water supply and drainage construction, which solves the problem that it is inconvenient to hoist pipes and make precise pipe connections in the existing technology.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A water supply and drainage construction auxiliary device, including a hoisting plate;

[0007] A pair of symmetrically placed lifting rings are fixedly installed on the lifting plate;

[0008] A pair of parallel sliding bars are provided below the lifting plate. The two sliding bars are in the same horizontal plane. An adjustment mechanism is provided on the lifting plate to drive the two sliding bars to move closer or further apart.

[0009] The lower end of each slider is rotatably connected to multiple vertically placed pivots, which are evenly distributed along the axis of the slider.

[0010] Each rotating shaft is fixedly fitted with a pair of symmetrically placed frustums. The frustums are coaxial with the corresponding rotating shafts. The two frustums are fixed to each other, and the diameter of the two frustums at the ends that are closer to each other is smaller than the diameter of the two frustums at the ends that are farther from each other.

[0011] Each slide bar is equipped with a locking mechanism, which can be used to lock the rotation of each shaft on the slide bar.

[0012] The principle and effect of the above technical solution are as follows:

[0013] During hoisting, two sliding bars are placed on either side of the pipe to be hoisted. The rotation of the shaft is locked by a locking mechanism, and the two sliding bars are driven to move closer together by an adjusting mechanism, so that the peripheral walls of the two truncated cones on each shaft are pressed against the peripheral wall of the pipe, thereby clamping and fixing the pipe. When the pipe is hoisted to the position where it needs to be connected, the locking mechanism releases the lock on the rotation of the shaft. At this time, the pipe is still hoisted between the two truncated cones, but since the shaft can rotate freely, the hoisted pipe can be manually pushed along the axis of the sliding bars to move the pipes closer together for splicing and installation. There is no need for a crane to hoist the two pipes closer together for connection. This achieves stable clamping and hoisting of the pipe, while selectively releasing the lock on the rotation of the shaft to allow manual pushing of the pipe along its own axis, thus facilitating precise connection and installation of the two pipes.

[0014] Each locking mechanism includes multiple gears. In any locking mechanism, the number of gears and the corresponding rotating shafts on the slide bar are equal and correspond one-to-one. The gears are fixedly sleeved on the corresponding rotating shafts. Each slide bar is fixedly equipped with a mounting rail. Each mounting rail is slidably connected with a rack placed in the same axis as the slide bar. Each rack meshes with each gear on the corresponding slide bar side.

[0015] Each locking mechanism also includes a pair of symmetrically placed hydraulic cylinders. The hydraulic cylinders are placed coaxially with the rack. The hydraulic cylinders are fixedly connected to the mounting rail through a fixing block. Limit blocks are fixed on the piston rods of the two hydraulic cylinders, and the rack is located between the two limit blocks.

[0016] The upper end of the rack is provided with a slot, which is placed coaxially with the rack and passes through both ends of the rack. The lower end of the mounting rail is slidably engaged in the slot.

[0017] The adjustment mechanism includes a pair of fixed bars fixed to the lower end of the lifting plate. The fixed bars are placed coaxially with the slide bars. The two slide bars are located between the two fixed bars. A pair of symmetrically placed slide rods are fixed between the two fixed bars. The two slide rods are located at the two ends of the slide bars respectively. A pair of first sliders are slidably sleeved on each slide rod. The two first sliders on any slide rod are fixed to the two slide bars respectively.

[0018] The adjustment mechanism also includes a pair of screws located between the two fixed bars. The screws are placed coaxially with the slide bar. The ends of the two screws that are far apart from each other are rotatably connected to the corresponding fixed bars. Each screw is fitted with a threaded second slider, which is fixed to the corresponding slide bar.

[0019] The two screws are placed on the same axis and the screw threads are in opposite directions. A dual-axis rotating motor is installed between the two screws. The two output ends of the dual-axis rotating motor are connected to the two screws respectively. The dual-axis rotating motor is fixedly connected to the lower end of the lifting plate.

[0020] The explanations of the nouns, conjunctions, or adjectives used in the above technical solutions are as follows:

[0021] Fixed connection: refers to a connection method in which two or more components are tightly connected together by welding, gluing or other methods, and cannot be easily separated.

[0022] Threaded connection: A method of connecting two parts together using a threaded structure. Threaded connections provide a strong connection and are relatively easy to disassemble and reconnect.

[0023] The beneficial effects of this utility model are:

[0024] 1. During hoisting, the two sliding bars are placed on both sides of the pipe to be hoisted. The rotation of the shaft is locked by the locking mechanism, and the two sliding bars are driven to move closer to each other by the adjusting mechanism, so that the peripheral walls of the two truncated cones on each shaft are pressed and contacted with the peripheral wall of the pipe, thereby achieving clamping and fixing of the pipe. Moreover, the method of setting two truncated cones on each shaft can be applied to the clamping and hoisting operations of various pipes with different diameters.

[0025] When the pipes are hoisted to the required position and the two pipes need to be connected, the locking mechanism only needs to release the lock on the rotating shaft. At this time, the pipes are still hoisted between the two truncated cones, but the rotating shaft can rotate freely. The hoisted pipes can be pushed manually along the axis of the sliding bar. There is no need for the crane to hoist the two pipes to move closer to each other for connection. This achieves stable clamping and hoisting of the pipes, while selectively releasing the lock on the rotating shaft to allow manual pushing of the pipes along their own axis, thus facilitating precise connection and installation of the two pipes.

[0026] 2. This application, through the coordinated arrangement of mounting rails, gears, racks, hydraulic cylinders, and limit blocks, can selectively lock or release each rotating shaft on either side synchronously. Attached Figure Description

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0034] This combination Figures 1 to 5This describes an embodiment of an auxiliary equipment for water supply and drainage construction. Specifically, the auxiliary equipment is constructed as a split structure, comprising components such as a lifting plate 100, sliding bars 200, an adjusting mechanism 300, a rotating shaft 400, a frustum 500, and a locking mechanism 600. During lifting, the two sliding bars 200 are placed on either side of the pipe to be lifted. The locking mechanism 600 locks the rotation of the rotating shaft 400, and the adjusting mechanism 300 drives the two sliding bars 200 to move closer together, so that the peripheral walls of the two frustums 500 on each rotating shaft 400 are pressed against the peripheral wall of the pipe, thereby achieving clamping and fixing of the pipe. When the pipe is lifted to a position close to the pipe... When two pipes need to be connected at the required installation location, the locking mechanism 600 only needs to release the lock on the rotation of the rotating shaft 400. At this time, the pipes are still suspended between the two truncated cones 500. However, since the rotating shaft 400 can rotate freely at this time, the suspended pipes can be manually pushed to move along the axis of the slide bar 200, so that the pipes are close to each other for splicing and installation. There is no need for a crane to lift and move the two pipes close to each other for connection. This achieves stable clamping and lifting of the pipes, while selectively releasing the lock on the rotation of the rotating shaft 400 to push the pipes to move along their own axis, avoiding excessive collision between the pipes during splicing and installation.

[0035] Please refer to Figures 1 to 5 A water supply and drainage construction auxiliary equipment, including a hoisting plate 100;

[0036] A pair of symmetrically placed lifting rings 101 are fixedly installed on the lifting plate 100;

[0037] Below the lifting plate 100, there is a pair of parallel sliding bars 200. The two sliding bars 200 are in the same horizontal plane. The lifting plate 100 is provided with an adjustment mechanism 300, which is used to drive the two sliding bars 200 to move closer or further apart.

[0038] The lower end of the slide bar 200 is rotatably connected to multiple vertically placed rotating shafts 400, and the multiple rotating shafts 400 are evenly distributed along the axis of the slide bar 200.

[0039] A pair of symmetrically placed frustums 500 are fixedly sleeved on each of the rotating shafts 400. The frustums 500 are placed coaxially with the corresponding rotating shafts 400. The two frustums 500 are fitted and fixed together, and the diameter of the two frustums 500 approaching each other is smaller than the diameter of the two frustums 500 away from each other.

[0040] Each slide bar 200 is equipped with a locking mechanism 600, which can be used to lock the rotation of each rotating shaft 400 on the slide bar 200;

[0041] When hoisting and transporting pipelines, use existing equipment such as cranes, and hook the crane hook onto the lifting ring 101;

[0042] During hoisting, the two sliding bars 200 are placed on both sides of the pipe to be hoisted. The rotation of the rotating shaft 400 is locked by the locking mechanism 600. Then, the hoisting plate 100 is moved up and down so that the mating surfaces of the two truncated cones 500 on each rotating shaft 400 are flush with the axis of the pipe to be hoisted. Then, the two sliding bars 200 are driven to move closer to each other by the adjusting mechanism 300. The sliding bars 200 drive the rotating shaft 400 and the truncated cones 500 so that the peripheral walls of the two truncated cones 500 on each rotating shaft 400 are pressed and contacted with the peripheral wall of the pipe, thereby achieving the clamping and fixing of the pipe.

[0043] Once the pipe is hoisted to the position close to the required docking location and the pipe is coaxially aligned with the pipe to be docked, the locking mechanism 600 only needs to release the lock on the rotating shaft 400. At this time, the pipe is still hoisted between the two truncated cones 500. However, since the rotating shaft 400 can rotate freely at this time, the hoisted pipe can be manually pushed to move along the axis of the slide bar 200, so that the pipes are close to each other for splicing and installation. There is no need for the crane to hoist the two pipes close to each other for docking. This achieves stable clamping and hoisting of the pipe, while selectively releasing the lock on the rotating shaft 400 to move the pipe along its own axis, so as to facilitate precise docking and installation of the two pipes and avoid excessive collision between the pipes when splicing and installing by hoisting with a crane.

[0044] Furthermore, this application, by setting two truncated cones 500 on each rotating shaft 400, can be applied to clamping and hoisting operations of various pipes with different diameters.

[0045] To facilitate synchronous locking of each rotating shaft 400 on the slide bar 200, each locking mechanism 600 includes multiple gears 601. The number of gears 601 in any locking mechanism 600 is equal to the number of rotating shafts 400 on the corresponding slide bar 200, and they correspond one-to-one. Each gear 601 is fixedly sleeved on the corresponding rotating shaft 400. Each slide bar 200 is fixedly equipped with a mounting rail 602, and each mounting rail 602 is slidably connected to a rack 603 placed coaxially with the slide bar 200. Each rack 603 meshes with each gear 601 on the corresponding side of the slide bar 200. By locking the rack 603 through sliding, the rack 603 locks each gear 601 on the corresponding side, thereby achieving synchronous locking of each rotating shaft 400 on the slide bar 200.

[0046] To facilitate locking the rack 603, the locking mechanism 600 also includes a pair of symmetrically placed hydraulic cylinders 604. The hydraulic cylinders 604 are coaxially placed with the rack 603 and are fixedly connected to the mounting rail 602 via fixing blocks. Limit blocks 605 are fixed on the piston rods of both hydraulic cylinders 604, and the rack 603 is located between the two limit blocks 605. When the two limit blocks 605 are driven by the two hydraulic cylinders 604 to approach the rack 603, and when the two limit blocks 605 abut against both ends of the rack 603, the rack 603 can be locked. When the limit blocks 605 are driven away from the rack 603, the rack 603 can slide along the mounting rail 602.

[0047] Each rack 603 has a slot 6031 at its upper end. The slots 6031 are placed coaxially with the rack 603 and pass through both ends of the rack 603. The lower ends of the mounting rails 602 are slidably engaged in the slots 6031. The matching arrangement of the slots 6031 and the mounting rails 602 improves the guiding nature of the rack 603's movement and also improves the stability of the connection between the mounting rails 602 and the rack 603.

[0048] To improve the guiding performance of the two slide bars 200 during movement, the adjustment mechanism 300 includes a pair of fixing bars 301 fixed to the lower end of the lifting plate 100. The fixing bars 301 are placed coaxially with the slide bars 200, and the two slide bars 200 are located between the two fixing bars 301. A pair of symmetrically placed slide rods 302 are fixed between the two fixing bars 301. The two slide rods 302 are located at both ends of the slide bars 200, and a pair of first sliders 303 are slidably sleeved on each slide rod 302. The two first sliders 303 on any slide rod 302 are fixed to the two slide bars 200 respectively. The guiding performance of the slide bars 200 during movement is improved by setting up the slide rods 302 and the first sliders 303.

[0049] The adjusting mechanism 300 also includes a pair of screws 304 located between the two fixed bars 301. The screws 304 are coaxially placed with the slide bar 302. The ends of the two screws 304 that are far apart from each other are rotatably connected to the corresponding fixed bars 301. Each screw 304 is fitted with a threaded second slider 305. The second slider 305 is fixed to the corresponding slide bar 200. Due to the arrangement of the slide bar 302 and the first slider 303, when the screw 304 is rotated, the screw 304 drives the second slider 305 to perform threaded transmission, which in turn drives the slide bar 200 to move.

[0050] To facilitate the rotation of the two screws 304 and control the two sliders 200 to move closer or further apart, the two screws 304 are placed coaxially with opposite thread directions. A dual-axis rotating motor 306 is provided between the two screws 304, with its two output ends connected to the two screws 304 respectively. The dual-axis rotating motor 306 is fixedly connected to the lower end of the lifting plate 100. When the dual-axis rotating motor 306 is turned on, it can synchronously drive the two screws 304 to rotate, and since the thread directions of the two screws 304 are opposite, it can drive the two second sliders 305 to move closer or further apart.
