Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water conservancy engineering equipment, in particular to a maintenance device for flood control and slope protection blocks. Background Art
[0002] Existing bank slope protection blocks are mostly solid hollow bricks that are attached to each other. When individual bricks are damaged or need to be replaced for other daily maintenance, since the adjacent bricks are very close to each other, a shovel is needed to pry the brick out in the gap between them, which can easily damage the adjacent bricks.
[0003] Hexagonal hollow slope protection bricks are one of the commonly used slope protection blocks. When replacing this shape of blocks, the bricks can be pried out from the internal opening due to the relatively large center opening. However, the hexagonal hollow slope protection bricks are also embedded in each other. If they are pried out from the internal opening, the adjacent bricks will still be squeezed and damaged when only one side is under force.
[0004] To this end, the present application designs a maintenance device for flood control and slope protection blocks of hexagonal hollow slope protection bricks, which can evenly stress all surfaces during the prying process to solve the above-mentioned problems. Utility Model Content

[0007] A central threaded shaft is erected in the center of the hexagonal hollow slope protection brick, and a hook rod which can slide up and down is arranged on the central threaded shaft. The hook rod is fixed by a locking device, and the lower end of the hook rod is placed under the hexagonal hollow slope protection brick. The hexagonal hollow slope protection brick can be lifted by lifting the central threaded shaft.
[0008] Furthermore, in order to better implement the present invention, a handle is welded to the top of the central threaded shaft, and a first locking nut, a sliding ring, a second locking nut, a locking plate and a third locking nut are sequentially arranged below the handle.
[0009] Furthermore, in order to better implement the utility model, a plurality of hook rods are hinged on the sliding ring, and a portion of the bottom of the hook rods is bent upward.
[0010] Furthermore, in order to better implement the utility model, three or six hook rods are provided.
[0011] Furthermore, in order to better implement the present invention, the clamping plate is a circular plate slidably connected to the central threaded shaft, and the outer edge of the clamping plate abuts against the hook rod by screwing the third locking nut upward.
[0012] Furthermore, in order to better implement the present invention, the top tightening plate can be hollowed out, and the hollowed-out part is convenient for inserting a pliers tool to tighten the third locking nut at the bottom.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.
[0021] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.
[0022] Figure 1-Figure 3This is a specific embodiment of the utility model, which is a maintenance device for flood control slope protection blocks, which is used for hexagonal hollow slope protection bricks 2 that are tightly laid on the slope protection ground 1. A central threaded shaft 3 is erected in the center of the hexagonal hollow slope protection brick 2, and a hook rod 305 that can slide up and down is provided on the central threaded shaft 3. The hook rod 305 is fixed by a locking device, and the lower end of the hook rod 305 is placed under the hexagonal hollow slope protection brick 2. By lifting the central threaded shaft 3, the hexagonal hollow slope protection brick 2 can be lifted.
[0023] A handle 301 is welded to the top of the central threaded shaft 3, and a first locking nut 302, a sliding ring 304, a second locking nut 303, a top plate 306 and a third locking nut 307 are sequentially arranged below the handle 301. A plurality of hook rods 305 are hinged on the sliding ring 304, and a portion of the bottom of the hook rod 305 is bent upward. Three or six hook rods 305 are arranged. The top plate 306 is a circular plate slidably connected to the central threaded shaft 3. When the third locking nut 307 is screwed upward, the outer edge of the top plate 306 abuts against the hook rod 305. The top plate 306 can be hollowed out, and the hollowed-out part is convenient for inserting a pliers tool to screw the third locking nut 307 at the bottom.
[0024] The specific usage of this embodiment is as follows:
[0025] Determine the hexagonal hollow slope protection brick 2 to be replaced, dig a hole 101 on the inner bottom edge of the brick with a small shovel, then erect the device of this embodiment at the center of the brick, slide the sliding ring 304 downward, so that the bottom of the hook rod 305 extends into the hollow 101, then tighten the first locking nut 302 and the second locking nut 303 to fix the sliding ring 304, and then tighten the third locking nut 307. The third locking nut 307 drives the top plate 306 to move upward until the outer edge of the top plate 306 presses the hook rod 305. At this time, the handle 301 can be directly pulled upward. In this way, the current hexagonal hollow slope protection brick 2 can be pulled out vertically upward under the condition of uniform force on multiple sides, which can avoid damaging the surrounding hexagonal hollow slope protection bricks 2.
[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
