Specific embodiments

[0035] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model; obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0037] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "provided with", "sheathed / connected", "connected", etc. should be understood in a broad sense. For example, "connected" can be a wall-mounted connection, a detachable connection, or an integral connection, it can be a mechanical connection, an electrical connection, a direct connection, or an indirect connection through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0038] As shown in the figure, an embodiment of the present utility model provides a slope protection construction device 2 for performing slope protection construction on a slope 1 from the bottom of the slope 1, including a winch 3, a telescopic arm 24, a base 25, a counterweight 26, an operation platform 27, and a connecting part 28.

[0039] As shown in the figure, the telescopic arm 24 is composed of at least two connecting rods 243 sleeved together, such that relative movement can occur axially between adjacent two of the connecting rods 243. The telescopic arm 24 includes a first end 241 and a second end 242. The first end 241 is hinged to the base 25, such that the telescopic arm 24 can rotate in a vertical plane with the first end 241 as the rotation center. As an equivalent alternative to this embodiment, in other embodiments, the first end 241 can also be hinged to the body of the winch 3. The second end 242 is provided with the operation platform 27 through the connecting part 28. The second end 242 is a free end and has a telescopic degree of freedom along the axis direction of the telescopic arm 24. The telescopic arm 24 provides a length compensation function by extending or retracting the second end 242, which can not only push the operation platform 27 close to the slope 1 for normal construction operations, but also prevent the telescopic arm 24 from getting stuck on the surface of the slope 1 and being unable to rotate downward. The telescopic power of the telescopic arm 24 is provided by a hydraulic system, and the hydraulic system is controlled by a remote controller. The power for the telescopic arm 24 to rotate is provided by the winch 3.

[0040] As shown in the figure, the winch 3 is fixed on the base 25 and includes a steel wire rope 231, a driving device, a transmission assembly 233, a drum 234, and a brake 235. In this embodiment, the driving device uses a small motor 232. The transmission assembly 233 transmits the power provided by the motor 232 to the drum 234, such that the drum 234 rotates around its own axis. One end of the steel wire rope 231 is fixed on the surface of the drum 234, such that the drum 234 can rotate to wind up or release the steel wire rope 231. The other end of the steel wire rope 231 extends out of the winch 3 and is connected to the second end 242 of the telescopic arm 24. At any length position of the telescopic arm 24, the steel wire rope 231 is not lower than the telescopic arm 24. Preferably, the telescopic arm 24 and the steel wire rope 231 form an acute angle with the second end 242 as the vertex. The winch 3 is a common lifting or traction device, so the specific structure and transmission cooperation of the winch 3 are obvious to those skilled in the art, and will not be elaborated herein. As an equivalent replacement of this embodiment, in other embodiments: the driving device can be a hydraulic press; the traction member can be a chain, a high-strength rope, etc.

[0041] Specifically, as shown in the figure, taking the right side of the slope protection construction device 2 on the slope 1 as an example, when the reel 234 rotates clockwise, the steel wire rope 231 is bundled because it is wound around the surface of the reel 234. At this time, the steel wire rope 231 generates a traction force F on the second end 242. The traction force F can be decomposed into a first component force F1 parallel to the telescopic arm 24 and a second component force F2 perpendicular to the telescopic arm 24. The second component force F2 causes the second end 242 to perform a circular motion centered on the first end 241, manifested as the telescopic arm 24 swinging clockwise centered on the first end 241, thereby lifting the operation platform 27 to a higher position. It can be understood that the elevation angle of the telescopic arm 24 does not exceed 90°, otherwise overall instability will occur. When the reel 234 rotates counterclockwise, the steel wire rope 231 is released, and the traction force F of the steel wire rope 231 on the second end 242 is less than the gravity, at this time the telescopic arm 24 rotates counterclockwise centered on the first end 241, and lowers the operation platform 27 to a lower position. During the process of lowering the operation platform 27, the telescopic arm 24 needs to be appropriately retracted to prevent the second section from jamming on the surface of the slope 1. The brake 235 provided on the winch 3 controls the release speed of the steel wire rope 231 by generating a frictional effect on the reel 234 or the transmission assembly 233, so as to lower the operation platform 27 safely. Both the brake 235 and the motor 232 are controlled by a remote controller.

[0042] To prevent the winch 3 from tipping over under the load, a fixing member is required to fix the base 25 on a flat ground. In this embodiment, a counterweight balance method is adopted to fix the base 25, that is: the counterweight 26 is arranged on the base 25 and on the side of the winch 3 away from the operation platform 27. Specifically, the counterweight 26 is made of concrete material, the length and width of the counterweight 26 are both 1.0 m, and the height is 0.2 m, so as to be stacked in the vertical direction according to the specific engineering situation. In other embodiments, the counterweight 26 can also be a thick steel plate. The counterweight 26 is preferably made of conventional building materials that can be obtained locally, and the volume and quantity are adjusted according to the specific engineering situation.

[0043] As shown in the figure, the connecting part 28 includes a truss 281 and at least one hydraulic rod 282. The truss 281 is a rigid space structure composed of several first steel members, hinged to the second end 242 of the telescopic arm 24 at point A on one side, and fixedly connected to the bottom or side of the operation platform 27 on the other side. One end of the hydraulic rod 282 is hinged to the telescopic arm 24 at point B, and the other end is hinged to the truss 281 at point C. The second end 242 of the telescopic arm 24, the hydraulic rod 282, and the truss 281 form a stable triangular structure with points A, B, and C as vertices. When the working angle of the telescopic arm 24 changes, the hydraulic rod 282 can adjust the operation platform 27 to a horizontal state by telescoping.

[0044] For the convenience of the following description, the direction along the height change of the surface of the slope 1 is defined as the longitudinal direction, and the direction along the horizontal extension is defined as the transverse direction. Since the telescopic arm 24 can only rotate in the vertical plane, the operation platform 27 can only be adjusted in height along the longitudinal direction of the slope 1 and cannot move along the transverse direction of the slope 1. To solve the above technical problem, as shown in the figure, the present embodiment also provides a slope protection construction system, which is composed of several groups of the slope protection construction devices 2 described above, arranged at intervals along the transverse direction of the slope 1, and an extension platform 3 is also connected between adjacent two groups of the operation platforms 27 to support the construction personnel to construct at any position in the transverse direction of the slope 1.

[0045] As shown in the figure, the extension platform 3 is a rigid plate-like structure composed of several second steel members spliced together. In the present embodiment, the second steel members are square steel pipes 31. Both ends of the extension platform 3 are respectively connected to the corresponding operation platform 27 through bolt assemblies. In other embodiments, the extension platform 3 and the operation platform 27 can also be detachably connected by mechanisms such as buckles and pins. For the construction system, the distance between adjacent two groups of the slope protection construction devices 2 along the transverse direction of the slope 1 is not greater than 10 m to prevent the extension platform 3 from breaking during loading due to excessive span.

[0046] As shown in the figure, when the distance between adjacent two groups of the operation platforms 27 is between 5 m and 10 m, several support rods 32 are further arranged at the bottom of the extension platform 3 to reinforce the extension platform 3. The support rods 32 are made of profiled steel materials. The support rods 32 are erected between adjacent two groups of operation platforms 27, and both ends are detachably connected to the operation platform 27 respectively. In the present embodiment, the specific connection method is bolt connection.

[0047] In summary, the slope protection construction device 2 provided by the embodiment of the present invention is assembled on a flat ground by simple devices or components such as the winch 3, the telescopic arm 24, the base 25, the counterweight 26, the operating platform 27 and the connecting part 28. It has a simple structure, occupies a small space, is easy to disassemble and transport, and has a high turnover efficiency. It not only meets the needs of carrying out slope protection construction on a narrow slope 1 grading platform, but also saves construction equipment costs to a large extent. Secondly, the winch 3 drives the telescopic arm 24 to rotate to a suitable working elevation angle, and cooperates with the length compensation function of the telescopic arm 24 itself to accurately position the operating platform 27 to any height on the surface of the slope 1, thereby realizing slope protection construction from the bottom of the slope 1. It is easy to operate and improves construction flexibility and construction accuracy. The slope protection construction system provided by the embodiment of the present invention adds a detachable expansion platform 3 between two adjacent groups of operating platforms 27, and when the span is large, additional support rods 32 are set up for reinforcement, supporting construction personnel to carry out construction at any position in the horizontal direction of the slope 1, and achieving full coverage of the construction working surface with a simple but stable structure.

[0048] The above description is merely a preferred specific implementation method of the present utility model and does not limit the patent scope of the present utility model. Any technical equivalent transformation made using the contents of the present utility model specification falls within the protection scope of the present utility model.
