Description

Technical Field

[0001] The utility model belongs to the field of pipeline transportation, and in particular relates to a simple pipeline transportation trolley. Background Art

[0002] A pipe transport trolley is a tool used to carry and transport pipes. This trolley usually has two wheels and can be easily moved on flat ground.

[0003] At present, the carts we use during construction are as follows: Figure 4 As shown, the trolley has a U-shaped frame and a crossbeam, and pipe clamps are respectively arranged at both ends of the crossbeam. During use, the pipeline is lifted by a lifting device, and then the pipe clamps at both ends are used to clamp the two ends of the pipeline to prevent the pipeline from falling off.

[0004] However, the cart has the following shortcomings during use:

[0005] 1. Before transporting the pipeline, it is necessary to use lifting equipment to lift the pipeline. After transporting it to the designated location, it is necessary to use lifting equipment to unload the pipeline. The operation is cumbersome and affects the efficiency of pipeline transportation.

[0006] 2. When the lifting equipment is used to load and unload the pipeline, two groups of workers need to control both ends of the beam to keep the beam stable, which increases the use of labor and poses certain risks during the pipeline lifting process.

[0007] Therefore, we propose a simple pipeline transport trolley to solve the above problems. Utility Model Content

Wheels 22 are respectively installed on the front and rear sides of the U-shaped frame 21. The two support arms 1 are respectively welded on the left and right sides of the U-shaped frame 21. A battery is installed on the rear side of the U-shaped frame 21.

[0032] It also includes a reel-up unit and two sets of hangers for connecting the ends of the pipe.

[0033] The winding unit includes a motor 64 , two steel wire ropes 62 and two guide wheels 61 . The two guide wheels 61 are respectively fixedly mounted on the bottoms of the two support arms 1 .

[0034] The motor 64 is mounted on the top of the U-shaped frame 21, and a bearing and a double-groove reel 63 are mounted on its output shaft. The bearing is mounted on the U-shaped frame 21, and a battery is electrically connected to the motor 64, and the battery supplies power to the motor 64 to avoid being bound by wires.

[0035] One end of the steel wire rope 62 is connected to the double-groove winding wheel 63, and the other end thereof passes through the guide wheel 61 and is connected to the sling. By connecting the two slings to the two ends of the pipeline respectively, and controlling the motor 64 to rotate forward, the motor 64 drives the double-groove winding wheel 63 to rotate. During the rotation, the double-groove winding wheel 63 synchronously winds up the two steel wire ropes 62 respectively, and then under the action of the guide wheels 61 on both sides, the pipeline slowly rises and leaves the ground, so that workers can push the cart to transport the pipeline, thereby improving the transportation efficiency of the pipeline.

[0036] The specific structure of the sling in this embodiment is as follows: the sling includes an upper arc-shaped clamping plate 52 and a lower arc-shaped clamping plate 53. The upper surface of the upper arc-shaped clamping plate 52 is fixedly connected with a lifting ring 51 for connecting with the wire rope 62. The lower arc-shaped clamping plate 53 is located below the upper arc-shaped clamping plate 52. A high-strength screw 54 is arranged in a through hole opened at the end thereof. The top end of the high-strength screw 54 is fixedly connected with the upper arc-shaped clamping plate 52, and the bottom end thereof is threadedly connected with an adjusting nut 55. By turning the adjusting nut 55, the lower arc-shaped clamping plate 53 is moved upward, and then the pipe wall is clamped by the cooperation of the upper arc-shaped clamping plate 52 and the lower arc-shaped clamping plate 53.

[0037] When used specifically, the utility model is a simple pipeline transport trolley. First, the trolley is moved to the top of the pipeline, then the upper arc clamping plate 52 is brought into contact with the outer surface of the pipeline, the lower arc clamping plate 53 is brought into contact with the inner wall of the pipeline, and the adjusting nut 55 is screwed. The upper arc clamping plate 52 and the lower arc clamping plate 53 cooperate to clamp the pipeline wall, and then the above operation steps are repeated to clamp the other end of the pipeline with another hanger;

[0038] After the two hangers are connected to the two ends of the pipeline, the motor 64 is controlled to rotate forward, and the motor 64 drives the double-groove winding wheel 63 to rotate. During the rotation process, the double-groove winding wheel 63 synchronously winds up the two steel wire ropes 62 respectively, and then under the action of the wire wheels 61 on both sides, the pipeline slowly rises and leaves the ground. Finally, the workers push the cart to transport the pipeline.

[0044] It also includes a fixing nut 72, a T-shaped support leg 71 and a C-shaped slider. The C-shaped slider is slidably arranged in the inner cavity of the support arm 1. The upper end of the T-shaped support leg 71 passes through the notch 72 and is hinged to the C-shaped slider. By pulling the T-shaped support leg 71 out of the support arm 1, when the C-shaped slider moves to the position of the notch 72, the T-shaped support leg 71 is flipped so that the bottom end of the T-shaped support leg 71 contacts the ground.

[0045] The fixing nut 72 is threadedly connected to the external thread and contacts the T-shaped support leg 71. The fixing nut 72 is rotated to fix the T-shaped support leg 71, so that the two support arms 1 are supported by the two T-shaped support legs 71 to ensure the stability of the trolley during the loading and unloading of the pipeline.
