Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy pipeline hoisting, in particular to a pipeline positioning grab hook for water conservancy projects. Background Art

[0002] During the laying of water conservancy pipelines, lifting equipment is often used to lift the pipelines. After placing them in the laying position, the pipelines are connected and installed.

[0003] When existing lifting equipment is used to suspend pipelines, they are mostly tied and fixed with suspension cloth belts. The tying and untying process is troublesome, and the fixation is not strong enough. Especially when suspending longer pipelines, even if the belt is tied in the middle of the pipeline, it is easy to cause the pipeline to slip. Therefore, we propose a pipeline positioning hook for water conservancy projects. Utility Model Content

[0012] As a preferred solution of the pipeline positioning grab hook for water conservancy projects described in the utility model, the grab plate is provided with an anti-slip pad that fits the pipeline.

[0013] As an optimal solution of the pipe positioning grab hook for water conservancy projects described in the utility model, the placement component includes a protruding rod arranged on the grab plate, a screw rod vertically passes through the protruding rod, a support block is provided at the bottom of the screw rod, and a hand wheel is provided at the top of the screw rod.

[0014] As a preferred solution of the pipeline positioning grab hook for water conservancy projects described in the utility model, the protruding rod is welded to the grab plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The distance between the front and rear grab plates can be adjusted according to the length of the pipe, and then the grab plates are driven to rotate by the reduction motor to stably clamp the pipe around the pipe, so that the subsequent connection of the lifting equipment's hook to the lifting ring is more stable during lifting. Compared with the belt method, clamping and loosening are more convenient, and even longer pipes can be stably grasped.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] As mentioned in the background art, conventional lifting equipment often uses suspension straps to tie and secure pipes during installation. This is cumbersome to tie and release, and the fixation is not strong enough. Especially when installing long pipes, even if the strap is tied in the middle of the pipe, it can easily cause the pipe to slip. The present utility model provides a pipe positioning hook for use in water conservancy projects. Example

[0023] Reference Figure 1 A pipe positioning grab hook for water conservancy projects includes a pipe 1 and a top frame 2. A lifting ring 3 is provided on the top of the top frame 2. The hook of the lifting equipment is connected to the lifting ring 3 to lift the top frame 2.

[0024] Mounting blocks 4 are provided at both ends of the bottom of the top frame 2, and distance adjustment components are provided on the mounting blocks 4 on both sides;

[0025] The front and rear ends of the distance adjustment components on both sides are provided with reduction motors 5, so that the distance between the reduction motors 5 at the front and rear ends can be adjusted. The output shaft of the reduction motor 5 is provided with an arc-shaped grab plate 6, and the grab plate 6 is closely connected to the pipe 1. The reduction motor 5 is used to drive the grab plate 6 to rotate;

[0026] The grab plates 6 are all provided with placement components.

[0027] The distance adjustment component includes two electric telescopic rods 7 with the same structure. The two electric telescopic rods 7 are respectively arranged at the front and rear ends of the mounting block 4, and a connecting block 8 is provided on the output end of the two electric telescopic rods 7. Among them, the front and rear reduction motors 5 are respectively arranged on the front and rear connection blocks 8. The electric telescopic rods 7 are operated to extend and retract according to the length of the pipeline 1, so that the distance between the front and rear grab plates 6 is changed, and then the grab plates 6 are driven to rotate by the reduction motor 5, so that the pipeline 1 can be stably clamped at all sides. The electrical components in the article are all powered and controlled by existing technologies.

[0028] An outer rod 9 is provided on the grab plates 6 at both ends of the front side, and an inner rod 10 is provided on the grab plates 6 at both ends of the rear side, which is slidably connected to the inner wall of the outer rod 9, so that the front and rear grab plates 6 on the same side can rotate synchronously and can also be supported when adjusting the distance, thereby improving the service life.

[0029] An anti-slip pad is provided on the gripping plate 6 and fits the pipe 1 to improve the stability of the clamping. Example

[0030] Reference Figure 1The placement component includes a protruding rod 11 arranged on the grab plate 6, a screw rod 12 vertically penetrates the protruding rod 11, a support block 13 is provided at the bottom of the screw rod 12, and a hand wheel 14 is provided on the top of the screw rod 12. In order to improve the structural strength, the protruding rod 11 is welded to the grab plate 6. When the positioning grab hook is not in use, the screw rod 12 is rotated by the hand wheel 14 so that the support block 13 contacts the ground, supporting each grab plate 6, which can be placed stably and is highly practical.

[0031] The rest of the structure is the same as that of Example 1.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
