Description

Technical Field

[0001] The present application relates to the technical field of petrochemical construction equipment, and more specifically, to a pipeline hoisting device for petrochemical construction. Background Art

[0002] Petroleum refers to a mixture of gaseous, liquid and solid hydrocarbons. It is a viscous, dark brown liquid with a natural appearance. It is called the "blood of industry". Petroleum has been widely used in all walks of life. Therefore, it is becoming increasingly important for the construction of petrochemical industry. Among them, when transporting petroleum, most of the ways of transporting petroleum are through laying petroleum pipelines. When laying petroleum pipelines, pipeline hoisting devices are used to facilitate the erection of pipelines. Chinese patent No. CN214243452U discloses a petroleum pipeline hoisting device, including The base, the left and right sides of the bottom end of the mounting frame are slidably connected with a left clamping jaw and a right clamping jaw, the bottom end of the turntable is fixedly connected with a rotating shaft and the rotating shaft passes through the shell and contacts with the base, the lower part of the rotating shaft is fixedly connected with a driven gear, a first motor is provided on the right side of the rotating shaft, the output end of the first motor is fixedly connected with a driving gear and the driving gear and the driven gear are meshed and connected, an elliptical wheel is provided inside the mounting frame and the short side of the elliptical wheel is in contact with the push block, the inner sides of the left and right clamping jaws are provided with clamping plates, the outer sides of the left and right clamping jaws are provided with a second motor, and a lead screw is provided between the second motor and the clamping plate. In view of the disclosed technology, the existing pipeline lifting device used in petrochemical construction, when the oil pipeline is erected, due to the certain weight of the oil pipeline, it is necessary to use the lifting device to move it to the installation point, and at the same time lift the oil pipeline to cooperate with the installation and fixing work of the pipeline. However, when installing a shorter oil pipeline, if a large lifting device is used, the large lifting device will be relatively wasteful during the lifting, which will increase the cost of oil pipeline installation. Therefore, there is an urgent need for a lifting device with a simple structure, easy to use, and capable of conveniently lifting short oil pipelines.

[0003] The document with the prior art publication number CN 220555615 U provides a pipeline hoisting device for petrochemical construction. The device uses the cooperation of the moving wheels to move the connecting frame to the top of the oil pipeline. Through the control of the control panel, the dual-axis motor drives the connecting rods at both ends to rotate, and then the connecting rods drive the line rollers on the rotating rods to rotate. The pull rope ends of the line rollers are connected to electric clamps through connecting rings and connecting plates. At this time, the pull ropes of the line rollers can drive the position of the electric clamps to descend, and then the electric clamps clamp and fix the surface of the oil pipeline. The two electric clamps can clamp the oil pipeline more firmly. Then the output end of the dual-axis motor is reversed. Similarly, by driving the electric clamps to rise, the oil pipeline can be hoisted to a suitable height. Then, through the moving wheels, the device drives the hoisted oil pipeline to move to a suitable position; so that the device can conveniently hoist short pipelines. The hoisting device has a simple structure and reduces the installation cost of the oil pipeline compared with hoisting with large hoisting equipment.

[0004] Although the above-mentioned prior art solution can achieve the relevant beneficial effects through the structure of the prior art, it still has the following defects: the device cannot adjust the distance between the two electric clamps during use, which results in the inability to adjust the distance between the two electric clamps. Therefore, the distance cannot be adjusted according to the length of the pipeline during use, which is inconvenient to store. At the same time, after the electric clamps clamp the pipeline and lack the necessary fixation after the pull rope is used, the pipeline will shake during movement.

[0005] In view of this, we propose a pipeline lifting device for petrochemical construction. Utility Model Content

[0006] 1. Technical problems to be solved

[0007] The purpose of this application is to provide a pipeline lifting device for petrochemical construction, which solves the technical problems in the above-mentioned background technology, realizes the ability to adjust the spacing of the pipeline clamps, facilitates adjustment according to the length of the pipeline, and facilitates storage after use, while avoiding the shaking of the pipeline after clamping.

[0008] 2. Technical solution

[0009] The technical solution of the present application provides a pipeline hoisting device for petrochemical construction, including a pipeline clamp, and also includes two gantries, fixed rollers at the bottom of the two gantries, multiple first telescopic rods fixed between the two gantries, and a second telescopic rod vertically fixed to each of the two gantries. The pipeline clamp is fixed on the second telescopic rod, and a telescopically adjustable lifting mechanism is fixed between the two gantries, and the lifting mechanism drives the second telescopic rod to extend and retract.

[0010] By adopting the above technical solution, the lifting mechanism drives the extension and retraction of the second telescopic rod, which in turn drives the pipe clamp to be raised and lowered. Under the action of the second telescopic rod, the shaking of the pipe after lifting is avoided. The two gantries are fixedly connected by multiple first telescopic rods. The first telescopic rods and the lifting mechanism are extended and retracted in the same direction. At this time, the distance between the two pipe clamps can be adjusted according to the length of the pipe. After use, the two gantries can be slid relative to each other to reduce the overall volume for easy storage.

One end of the first sleeve is fixed to the gantry on one side, and one end of the first insertion rod is fixed to the gantry on the other side.

[0012] By adopting the above technical solution, the first insertion rod is slidably inserted into the first sleeve to adjust the distance between the two gantries, and the locking screw is fixed after being abutted against the first insertion rod.

[0013] As an optional solution to the technical solution of the present application document, the lifting mechanism includes multiple ear plates, two reels, a telescopic shaft, a servo motor, a worm, a worm gear and a cable. Ear plates are fixedly installed on both sides of the gantry, a reel is rotatably arranged between the two ear plates, a telescopic shaft is fixed between the two reels, the servo motor is fixed on one side of the ear plate, the output shaft of the servo motor is coaxially fixed with the worm, and the worm gear is coaxially fixed with one side of the reel and engages with the worm.

The servo motor drives the worm to rotate, the worm drives the worm wheel to rotate, and the worm wheel drives the reel on one side to rotate. The reel drives the reel on the other side to rotate synchronously in the same direction through the telescopic shaft. One end of the cable is fixed to the reel, and the other end is fixed to the second telescopic rod, so that the pipe clamp can be raised and lowered by winding the cable around or releasing the cable on the reel.

[0015] As an optional solution of the technical solution of this application document, the telescopic shaft includes a third sleeve and a third insertion rod slidably inserted into the third sleeve, and the third insertion rod is an angular rod.

[0016] By adopting the above technical solution, one end of the third sleeve is coaxially fixed on the reel on one side, and the third insertion rod is fixed on the reel shaft on the other side. In addition, through the ridge rod structure design of the third insertion rod, the telescopic shaft can be adjusted by sliding the third insertion rod in the third sleeve, thereby realizing the telescopic adjustment of the telescopic shaft and ensuring normal transmission.

[0018] By adopting the above technical solution, the cable passes through the gantry and the second sleeve and is fixed to the upper end of the second insertion rod. The ridged rod structure of the second insertion rod can prevent the second insertion rod from rotating within the second sleeve.

[0026] The present application is further described in detail below with reference to the accompanying drawings.

[0027] A pipeline hoisting device for petrochemical construction includes a pipeline clamp 3, two gantries 1, fixed rollers 11 at the bottom of the two gantries 1, multiple first telescopic rods 2 fixed between the two gantries 1, second telescopic rods 4 vertically fixed to both gantries 1, the pipeline clamp 3 fixed to the second telescopic rod 4, and a telescopically adjustable lifting mechanism 5 fixed between the two gantries 1, which drives the second telescopic rod 4 to extend and retract.

[0028] Reference Figure 1-Figure 3 , a rib 12 is fixed on the right-angle side of the gantry 1 to improve the supporting strength of the gantry 1, and the second telescopic rod 4 is driven to extend and retract through the lifting mechanism 5, which in turn drives the pipe clamp 3 to be raised and lowered. Under the action of the second telescopic rod 4, the shaking of the pipe after lifting is avoided at the same time. The two gantries 1 are fixedly connected by multiple first telescopic rods 2. Through the same-direction telescopic adjustment of the first telescopic rods 2 and the lifting mechanism 5, the distance between the two pipe clamps 3 can be adjusted according to the length of the pipe. After use, the two gantries 1 can be slid relative to each other to reduce the overall volume for easy storage.

[0029] The first telescopic rod 2 includes a first sleeve 21, a first insertion rod 22 slidably inserted in the first sleeve 21, and a locking screw 23 threadedly connected to the first sleeve 21 and abutting against the first insertion rod 22. One end of the first sleeve 21 is fixed to the gantry 1 on one side, and one end of the first insertion rod 22 is fixed to the gantry 1 on the other side.

[0030] Reference Figure 1 and Figure 2 The first rod 22 is slidably inserted into the first sleeve 21 to adjust the distance between the two gantries 1, and the locking screw 23 is fixed after being abutted against the first rod 22.

[0031] The lifting mechanism 5 includes multiple ear plates 57, two reels 55, a telescopic shaft 54, a servo motor 51, a worm 52, a worm gear 53 and a cable 56. Ear plates 57 are fixedly installed on both sides of the gantry 1. A reel 55 is rotatably set between the two ear plates 57. The telescopic shaft 54 ​​is fixed between the two reels 55. The servo motor 51 is fixed on one side of the ear plate 57. The output shaft of the servo motor 51 is coaxially fixed with the worm 52. The worm gear 53 is coaxially fixed with one side of the reel 55 and engages with the worm 52.

[0032] Reference Figure 1-Figure 3Both axial ends of the reel 55 are rotatably arranged between the two ear plates 57 through bearings. The two reels 55 are connected by a telescopic shaft 54. The servo motor 51 drives the worm 52 to rotate, and the worm 52 drives the worm gear 53 to rotate. The worm gear 53 drives the reel 55 on one side to rotate. The reel 55 drives the reel 55 on the other side to rotate synchronously in the same direction through the telescopic shaft 54. One end of the cable 56 is fixed to the reel 55, and the other end is fixed to the second telescopic rod 4. The cable 56 is wound around or released by the reel 55 to realize the lifting and lowering of the pipe clamp 3.

[0033] The telescopic shaft 54 ​​includes a third sleeve 541 and a third insertion rod 542 slidably inserted into the third sleeve 541 . The third insertion rod 542 is a rectangular rod.

[0034] One end of the third sleeve 541 is coaxially fixed to the reel 55 on one side, and the third insertion rod 542 is fixed to the shaft of the reel 55 on the other side. The third insertion rod 542 is designed with a rectangular rod structure, so that the third insertion rod 542 can be adjusted by sliding the third insertion rod 542 in the third sleeve 541 to achieve telescopic adjustment of the telescopic shaft 54 ​​and ensure normal transmission.

[0035] The second telescopic rod 4 includes a second sleeve 41 and a second insertion rod 42 slidably inserted into the second sleeve 41 . The second insertion rod 42 is an angular rod, and the pipe clamp 3 is fixed on the second insertion rod 42 .

[0036] Reference Figure 3 After the cable 56 passes through the gantry 1 and the second sleeve 41 and is fixed to the upper end of the second insertion rod 42, the ridged rod structure of the second insertion rod 42 can prevent the second insertion rod 42 from rotating in the second sleeve 41. Therefore, when the pipe clamp 3 is raised or lowered, under the action of the second telescopic rod 4, the problem of the lifted pipe and the pipe clamp 3 shaking between the gantry 1 can be avoided.

[0037] Working principle: The distance between the two gantries 1 is adjusted according to the length of the pipeline, so that the first insertion rod 22 is slidably inserted in the first sleeve 21 and then fixed by the locking screw 23. The servo motor 51 drives the worm 52 to rotate forward, and the worm 52 drives the worm wheel 53 to rotate clockwise and release the cable 56. The second insertion rod 42 extends downward and clamps the pipeline through the pipeline clamp 3. Then the servo motor 51 drives the worm 52 to rotate in the opposite direction, and the worm 52 drives the worm wheel 53 to rotate counterclockwise and wind the cable 56, so that the second insertion rod 42 retracts into the second sleeve 41 to lift the pipeline clamp 3 and the pipeline.
