Description

Technical Field

[0001] This application relates to the field of pipeline hoisting technology, and in particular to a gas pipeline hoisting construction device. Background Technology

[0002] Currently, natural gas is generally supplied via pipeline transportation. Natural gas pipeline transportation has advantages such as low transportation costs, small land occupation, and fast construction. When maintaining gas pipelines, hoisting equipment is used to lower the pipelines into the excavated trenches.

[0003] In the prior art, such as Chinese Patent No. CN222665124U, a municipal gas pipeline hoisting and construction device is disclosed. In the above technical solution, the clamping rod is retracted into the ring frame to release and hold the hoisted pipeline. However, even with the ring frame, the size of the ring frame is still larger than the diameter of the pipeline, which may still cause spatial interference in areas with narrow trenches, affecting its use.

[0004] Based on this, this application proposes a gas pipeline hoisting and construction device. Utility Model Content

[0005] The purpose of this application is to provide a gas pipeline hoisting and construction device to solve the problems mentioned in the background art.

[0006] The technical solution of this application embodiment is:

[0007] This application provides a gas pipeline hoisting and construction device, which includes a crossbeam and a pipeline body, and further includes:

[0008] The lifting component is slidably connected inside the crossbeam. A cavity is provided on the lower surface of the lifting component. An electric push rod is fixedly connected to one inner wall of the cavity. A push block is fixedly connected to the output end of the electric push rod.

[0009] A fixing block is fixedly connected to the inner wall of the cavity. Two through holes are opened on the lower surface of the fixing block. A first sleeve and a second sleeve are fixedly connected to the inner walls of the two through holes respectively. A sliding plate is slidably connected to the inner walls of the first sleeve and the second sleeve.

[0010] Two pressure rods are slidably connected to the upper surfaces of two corresponding slide plates, and suction cups are fixedly connected to the bottom ends of both pressure rods.

[0011] In one embodiment of this application, a trapezoidal block is fixedly connected to the top of one of the pressure rods, a connecting rod is fixedly connected to one side of the trapezoidal block, and one end of the connecting rod is fixedly connected to the top of the other pressure rod.

[0012] In one embodiment of this application, springs are fitted onto the surfaces of both pressure rods, the top ends of the two springs are fixedly connected to the inner top walls of the first sleeve and the second sleeve, respectively, and the bottom ends of the two springs are fixedly connected to the upper surfaces of the corresponding two slide plates.

[0013] In one embodiment of this application, a screw is rotatably connected to the inner wall of the crossbeam, the lifting component is threadedly connected to the surface of the screw, a driving component is fixedly installed on one side of the crossbeam, and the output end of the driving component is fixedly connected to one end of the screw.

[0014] In one embodiment of this application, a clearance groove is provided on one side of the crossbeam, the surface of the lifting component is slidably connected to the inside of the clearance groove, and two lifting lugs are fixedly connected to the upper surface of the crossbeam, with the same sling fixedly installed on the two lifting lugs.

[0015] In one embodiment of this application, the driving component is a motor.

[0016] Compared with the prior art, the embodiments of this application have at least the following beneficial effects:

[0017] 1. In this embodiment, the drive unit rotates the screw, causing the lifting component to slide along the crossbeam. The horizontal position of the lifting component is adjusted so that it aligns with the center of the pipe and is inserted into the pipe body, thus enabling the pipe body to be lifted. This avoids the installation in the ditch being affected by the lifting device (such as the ring frame in the prior art) being larger than the pipe body.

[0018] 2. In this embodiment, an electric push rod is provided in the cavity on the lower surface of the lifting component. Activating the electric push rod pushes the push block. The push block squeezes the trapezoidal block, which, through the connecting rod, drives the two pressure rods to move downwards synchronously, causing the suction cup to contact the pipe surface and form a negative pressure adsorption. The spring contracts under pressure, providing cushioning and ensuring a tight fit between the suction cup and the pipe, enhancing the fixing effect. Attached Figure Description

[0025] The embodiments of this application are described in detail below, and the technical solutions in the embodiments of this application are clearly and completely described. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the embodiments of this application.

[0026] This application provides an improved gas pipeline hoisting and construction device. The technical solution of this application embodiment is as follows:

[0027] like Figures 1-3 As shown, this embodiment proposes a gas pipeline hoisting construction device. The hoisting construction device includes a crossbeam 1 and a pipeline body 4. The crossbeam 1 serves as the main support structure of the device, bearing the weight of the hoisting components 5 and the pipeline body 4 to ensure overall stability. The hoisting construction device also includes:

[0028] The lifting component 5 is slidably connected inside the crossbeam 1. A cavity 6 is formed on the lower surface of the lifting component 5. An electric push rod 7 is fixedly connected to one inner wall of the cavity 6. A push block 8 is fixedly connected to the output end of the electric push rod 7. The electric push rod 7 provides power to push the trapezoidal block 13 to control the lifting and lowering of the suction cup 20. The fixing block 9 is fixedly connected to the inner wall of the cavity 6. Two through holes are formed on the lower surface of the fixing block 9. A first sleeve 15 and a second sleeve 16 are fixedly connected to the inner walls of the two through holes, respectively. A sliding plate 17 is slidably connected to the inner walls of the first sleeve 15 and the second sleeve 16. The first sleeve 15 and the second sleeve 16 support the pressure rod 18 and the spring 19 to ensure the stable adsorption and rebound of the suction cup 20. The fixing block 9 is made of high-strength cast iron or aluminum alloy. Self-lubricating copper sleeves or PTFE bushings can be embedded in the inner walls of the first sleeve 15 and the second sleeve 16 to reduce the frictional resistance of the pressure rod 18.

[0029] Two pressure rods 18 are slidably connected to the upper surfaces of the corresponding two slide plates 17. The bottom ends of the two pressure rods 18 are fixedly connected to suction cups 20. The pressure rods 18 transmit thrust, so that the suction cups 20 are tightly attached to the surface of the pipe. The suction cups 20 provide negative pressure adsorption force to fix the pipe.

[0030] Among them, the electric actuator can be the existing DYTP type electro-hydraulic actuator or the BTDT series explosion-proof electric actuator.

[0031] like Figure 3 As shown, in one embodiment, a trapezoidal block 13 is fixedly connected to the top of one of the pressure rods 18, a connecting rod 14 is fixedly connected to one side of the trapezoidal block 13, and one end of the connecting rod 14 is fixedly connected to the top of the other pressure rod 18.

[0032] It is understandable that springs 19 are fitted on the surfaces of both pressure rods 18. The springs 19 provide a rebound force when the suction cup 20 is disengaged from the pipe, which helps the pressure rods 18 to reset. The top ends of the two springs 19 are fixedly connected to the inner top walls of the first sleeve 15 and the second sleeve 16, respectively, and the bottom ends of the two springs 19 are fixedly connected to the upper surfaces of the corresponding two slide plates 17, respectively.

[0033] like Figure 2 and Figure 3 As shown, in one embodiment, a screw 11 is rotatably connected to the inner wall of the crossbeam 1, and a lifting component 5 is threadedly connected to the surface of the screw 11. A driving component 12 is fixedly installed on one side of the crossbeam 1, and the output end of the driving component 12 is fixedly connected to one end of the screw 11.

[0034] In one implementation method, the driving component 12 in this embodiment is a motor.

[0035] In one embodiment, a clearance groove 10 is provided on one side of the crossbeam 1, and the surface of the lifting component 5 is slidably connected to the inside of the clearance groove 10. Two lifting lugs 2 are fixedly connected to the upper surface of the crossbeam 1, and the same sling 3 (such as a wire rope sling) is fixedly installed on the two lifting lugs 2.

[0036] The usage process of this embodiment will be further explained below.

[0037] First, when in use, with the help of a pipe hoisting machine or crane, the entire device is hoisted above the pipe body 4 using the lifting lugs 2 and slings 3 on the crossbeam 1. The drive unit 12 is started, which drives the screw 11 to rotate, causing the hoisting component 5 to slide along the crossbeam 1. The horizontal position of the hoisting component 5 is adjusted so that it is aligned with the center of the pipe and inserted into the pipe body 4, thereby allowing the pipe body 4 to be hoisted.

[0038] Next, an electric push rod 7 is installed in the cavity 6 on the lower surface of the lifting component 5. The electric push rod 7 is activated to push the push block 8. The push block 8 squeezes the trapezoidal block 13, which drives the two pressure rods 18 to move downward synchronously through the connecting rod 14, so that the suction cup 20 contacts the pipe surface and forms a negative pressure adsorption. The spring 19 is compressed and contracts, providing cushioning and ensuring that the suction cup 20 fits tightly with the pipe, enhancing the fixing effect.

[0039] Finally, after adsorption and fixation, the crossbeam 1 is lifted by the sling 3, the pipe is lifted and moved to the target position, the drive component 12 can readjust the position of the lifting component 5, and move it out from the inside of the pipe body 4. After reaching the target position, the electric push rod 7 retracts, the push block 8 releases the pressure on the trapezoidal block 13, the spring 19 rebounds, pushing the slide plate 17 and the pressure rod 18 to move upward, the suction cup 20 disengages from the pipe, and the release is completed.

[0040] The technical means disclosed in the embodiments of this application are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in the embodiments of this application are common knowledge to those skilled in the art.
