Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering construction technology, specifically to a pipeline handling device for water conservancy engineering construction. Background Technology

[0002] Water conservancy engineering construction is a highly specialized and important field. It refers to the entire process of transforming the blueprints of water conservancy engineering projects into physical structures according to design drawings and specifications. During construction, pipelines need to be laid to transport liquids.

[0003] For example, the patent application number published on the China Patent Network is 202322713262.X, and the patent title is: A pipe handling device for water conservancy projects, including a flat plate; a fixing mechanism installed on the top of the flat plate; and a support plate disposed under the flat plate; wherein, two sets of lifting mechanisms are installed on the top of the support plate for adjusting the height of the flat plate. The pipe handling device for water conservancy projects provided by this utility model uses a fixing mechanism, in which a bidirectional screw and a threaded block move, to allow two clamping plates to move relative to each other, so that multiple sets of clamping plates can fix the beginning, middle, and end of the pipe respectively, improving the fixing effect and increasing stability. The lifting mechanism, in which gears engage with the toothed grooves on the lifting rod, allows the platform to be adjusted up and down, enabling the pipe to be adjusted to a suitable height for easy handling by workers.

[0004] However, existing handling equipment requires additional hoisting to transport the pipeline to the surface of the equipment. The pipeline hoisting process takes a lot of time and effort, and the frequent use of cranes will lead to a significant increase in the handling cost of the tank.

[0005] Therefore, it is necessary to redesign and modify the pipeline handling equipment used in water conservancy project construction. Utility Model Content

[0006] To address the problems mentioned in the background art, the purpose of this utility model is to provide a pipeline handling device for water conservancy engineering construction, which has the advantage of improving handling efficiency. It solves the problems of existing handling devices requiring additional hoisting to transport pipelines to the surface of the device, which consumes a lot of time and effort during pipeline handling, and the frequent use of cranes leading to a significant increase in the handling cost of the tank.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a pipeline handling device for water conservancy engineering construction, comprising a frame; The front and back of the frame are movably connected to hooks via pins. A pipe workpiece is provided on the left side of the frame. The hook extends to the bottom of the pipe workpiece on the side away from the frame. The hook can swing around the pin as an axis to lift the pipe workpiece. A transmission structure is provided at the bottom of the frame, which can control the swing angle of the hook.

[0008] As a preferred embodiment of this utility model, the transmission structure includes a connecting plate disposed at the bottom of the frame, a push rod fixedly connected to the left end of the connecting plate, the two ends of the push rod extending to the bottom of two hooks respectively, and an adjustment structure disposed on the right side of the frame, the adjustment structure being able to control the vertical lifting and lowering of the connecting plate.

[0009] As a preferred embodiment of this utility model, the right side of the adjustment structure is fixedly connected to a connecting frame on the right side of the frame. A screw is movably connected inside the connecting frame via a bearing. A connecting plate is sleeved on the surface of the screw and threadedly connected to the screw. The top end of the screw passes through the connecting frame and extends to the top of the connecting frame. A rotating wheel located at the top of the connecting frame is fixedly connected to the surface of the screw.

[0010] As a preferred embodiment of this invention, both ends of the push rod are fitted with rubber sleeves, the outer surface of which contacts the bottom of the hook, and the rubber sleeves are elastic.

[0011] As a preferred embodiment of this utility model, a crossbeam is fixedly connected inside the frame, and a guide rod is fixedly connected to the bottom of the crossbeam. The side of the guide rod away from the crossbeam passes through a connecting plate and is slidably connected to the connecting plate.

[0012] As a preferred embodiment of this utility model, a limiting plate is fixedly connected to the top of the connecting plate. The side of the limiting plate away from the connecting plate can penetrate the frame and extend to the top of the frame. The limiting plate can block the pipe workpiece rolling on the hook surface.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model adopts a hook that is movably connected to the frame by a pin shaft and sets up a transmission structure to control its swing angle, thereby realizing the active opening and closing of the hook. This allows the device to directly lift or lower the pipe workpiece from the bottom by swinging the hook, without the need for additional equipment such as cranes for clamping. This fundamentally solves the problems of time-consuming, labor-intensive and costly traditional handling methods and significantly improves the efficiency of pipe handling.

[0014] 2. This utility model effectively converts the single vertical lifting motion into the rotational swing of the hook by setting up a transmission structure consisting of a connecting plate and a push rod, and connecting it with an adjustment structure that can control the vertical lifting and lowering of the connecting plate.

[0015] 3. This utility model uses a screw as the core component of the adjustment structure. Operators can easily control the lifting height of the connecting plate by simply rotating the wheel. The screw drive has a self-locking function and can be locked at any position.

[0016] 4. This utility model uses elastic rubber sleeves at both ends of the push rod to buffer and increase friction when it contacts the bottom of the hook. This not only reduces wear and noise caused by hard contact between metal parts, but also provides more stable friction.

[0017] 5. This utility model provides precise guidance and limiting for the vertical lifting and lowering of the connecting plate by setting a guiding mechanism composed of a crossbeam and a guide rod. The guide rod passes through the connecting plate and is slidably connected to it, which effectively prevents the connecting plate from deflecting or jamming during the lifting and lowering process, and ensures the smoothness of the entire transmission action and the structural stability.

[0018] 6. This utility model provides a limiting plate at the top that rises and falls synchronously with the connecting plate, allowing it to extend above the frame. When the pipe is lifted onto the frame, the limiting plate acts as a stop that moves in conjunction with the hook state, reducing the impact force generated when the pipe workpiece rolls.

[0021] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 4 As shown, the present invention provides a pipeline handling device for water conservancy engineering construction, including a frame 1; The front and back of the frame 1 are movably connected to hooks 2 via pins. A pipe workpiece 3 is provided on the left side of the frame 1. The side of the hook 2 away from the frame 1 extends to the bottom of the pipe workpiece 3. The hook 2 can swing around the pin as the axis and lift the pipe workpiece 3. A transmission structure is provided at the bottom of the frame 1. The transmission structure can control the swing angle of the hook 2.

[0023] refer to Figure 3 The transmission structure includes a connecting plate 4 located at the bottom of the frame 1. A push rod 5 is fixedly connected to the left end of the connecting plate 4. Both ends of the push rod 5 extend to the bottom of two hooks 2 respectively. An adjustment structure is provided on the right side of the frame 1. The adjustment structure can control the vertical lifting and lowering of the connecting plate 4.

[0024] As a technical optimization of this utility model, by setting a transmission structure consisting of a connecting plate 4 and a push rod 5, and connecting an adjustment structure that can control the vertical lifting and lowering of the connecting plate 4, the single vertical lifting motion is effectively converted into the rotational swing of the hook 2.

[0025] refer to Figure 2 The right side of the adjustment structure is fixedly connected to the connecting frame 6 on the right side of the frame 1. The inside of the connecting frame 6 is movably connected to the screw 7 through the bearing. The connecting plate 4 is sleeved on the surface of the screw 7 and threadedly connected to the screw 7. The top end of the screw 7 passes through the connecting frame 6 and extends to the top of the connecting frame 6. The surface of the screw 7 is fixedly connected to the wheel 8 located at the top of the connecting frame 6.

[0026] As a technical optimization of this utility model, by using screw 7 as the core component of the adjustment structure, the operator can easily control the lifting height of the connecting plate 4 by simply rotating the wheel 8. The screw 7 transmission has a self-locking function and can be locked at any position.

[0027] refer to Figure 1 Both ends of the push rod 5 are fitted with rubber sleeves 9, the outer surface of the rubber sleeves 9 is in contact with the bottom of the hook 2, and the rubber sleeves 9 are elastic.

[0028] As a technical optimization of this utility model, by sleeved with elastic rubber sleeves 9 at both ends of the push rod 5, it plays a role in buffering and increasing friction when it contacts the bottom of the hook 2. This not only reduces wear and noise caused by hard contact between metal parts, but also provides more stable friction.

[0029] refer to Figure 3 A crossbeam 10 is fixedly connected inside the frame 1. A guide rod 11 is fixedly connected to the bottom of the crossbeam 10. The side of the guide rod 11 away from the crossbeam 10 passes through the connecting plate 4 and is slidably connected to the connecting plate 4.

[0030] As a technical optimization of this utility model, a guiding mechanism consisting of a crossbeam 10 and a guide rod 11 is set up. The guide rod 11 passes through the connecting plate 4 and is slidably connected to it, providing precise guidance and limiting for the vertical lifting and lowering of the connecting plate 4. This effectively prevents the connecting plate 4 from deflecting or getting stuck during the lifting and lowering process, ensuring the smoothness of the entire transmission action and the stability of the structure.

[0031] refer to Figure 4 A limiting plate 12 is fixedly connected to the top of the connecting plate 4. The side of the limiting plate 12 away from the connecting plate 4 can penetrate the frame 1 and extend to the top of the frame 1. The limiting plate 12 can block the pipe workpiece 3 rolling on the surface of the hook 2.

[0032] As a technical optimization of this utility model, a limiting plate 12 is set at the top that is raised and lowered synchronously with the connecting plate 4, so that it can extend above the frame 1. When the pipe is lifted onto the frame 1, the limiting plate 12 acts as a stop that can be linked with the state of the hook 2, reducing the impact force generated when the pipe workpiece 3 rolls.

[0033] The working principle and usage process of this utility model are as follows: The operator pushes the frame 1 to the side of the pipe, so that the hook 2 is located on one side of the pipe workpiece 3. Then, the operator rotates the right-side rotating wheel 8 clockwise, which drives the connecting plate 4 to descend through the screw 7, thereby driving the push rod 5 to descend. At this time, the hook 2 loses its bottom support and swings downward with its pin as the axis, so that its front end can smoothly extend into the bottom of the pipe. Then, the operator rotates the rotating wheel 8 counterclockwise, and the connecting plate 4 rises under the drive of the screw 7, pushing the push rod 5 upward to lift the tails of the two hooks 2. The front ends of the hooks 2 swing upward, thereby lifting the pipe off the ground. During this process, the limiting plate 12, which is fixed to the connecting plate 4, rises synchronously to block the pipe on the frame 1 laterally. After the pipe workpiece 3 is lifted and stabilized, it slides on the inclined surface of the hook 2 and moves to the top of the frame 1. When the pipe workpiece 3 contacts the limiting plate 12, the loading operation can be repeated, and then the entire device can be moved for transportation.

[0034] In summary, this pipeline handling device for water conservancy construction utilizes a hook 2 that is movably connected to the frame 1 via a pin, and a transmission structure controls its swing angle. This enables the hook 2 to actively open and close, allowing the device to directly lift or lower the pipeline workpiece 3 from the bottom through the swing of the hook 2, without the need for additional equipment such as cranes for clamping. This fundamentally solves the problems of time-consuming, labor-intensive, and costly traditional handling methods, and significantly improves the efficiency of pipeline handling.
