Description

Technical Field

[0001] The utility model relates to a support structure, and particularly to a support structure for water conservancy and hydropower projects. Background Art

[0002] During the construction of water conservancy and hydropower projects, it is necessary to position the laid pipelines through brackets. The Chinese patent with the application number CN202320209945.9 provides a solution called a support frame for water conservancy and hydropower construction. When adjusting the height, by removing the fixing bolts in the first threaded hole and the second threaded hole, and then driving the threaded rod to rotate by driving the rotating motor, the lifting plate can move up and down, so as to adjust the height. After the height adjustment is completed, the fixing bolts are fixed in the first threaded hole and the corresponding second threaded hole; and two clamping plates are driven to move by several electric push rods, so as to position the pipeline located between the two clamping plates; this solution can not only support and position the pipeline, but also adjust the support height according to actual needs, thus improving the applicability; however, on the one hand, when adjusting the height of this solution, it is necessary to align the first threaded hole and the second threaded hole for use, and the second threaded hole is arranged on the side of the lifting plate, and the lifting plate is located inside the base, making it inconvenient to view the second threaded hole, thus increasing the difficulty of aligning the first threaded hole and the second threaded hole; on the other hand, the lifting plate and the clamping plate are respectively driven to move by the rotating motor and the electric push rod, which results in that when using this solution, not only the motor but also the electric push rod need to be installed, which increases the manufacturing cost, and also needs to be powered on for use, reducing the convenience during use.

[0046] The number of the locking mechanisms 55 is two, and the two locking mechanisms 55 have the same structure and are symmetrically arranged with each other. Specifically, during use, by rotating the locking screws 16 of the two locking mechanisms 55, the two locking heads 13 are driven to move in opposite directions by the rotation of the two locking screws 16, so that the inner walls of the respective locking heads 13 are in contact with and tightly press against the outer wall of the worm 9, thereby preventing the worm 9 from rotating, and thus achieving locking.

[0047] The preferred specific embodiments of the present utility model have been described in detail above. It should be understood that those of ordinary skill in the art can make many modifications and variations based on the concept of the present utility model without creative labor. Therefore, all technical solutions that can be obtained by those skilled in the art in the technical field of the present application based on the concept of the present utility model through logical analysis, reasoning or limited experiments on the basis of the prior art should be within the protection scope determined by the claims.
