DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments only represent some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without any creative effort belong to the scope of protection of the present application.

[0021] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0022] The corresponding technical terms in the embodiments will be described as follows:

[0023] Mine closure, also known as mine closure or mine closure, refers to the process of completely closing a mine (including mine area, pit head or open pit) after mining ends, and performing safety treatment and environmental protection according to regulations. This process involves the closure of the mine, the removal of equipment, the abandonment of facilities, and other treatments to ensure that the mine will not harm the environment and personnel after closure, while reasonably utilizing and protecting mineral resources.

[0024] A winch, also known as a hoist, is a type of lifting machine that is mainly composed of a drum, steel wire rope, and other components. It uses the drum to wind up or pull down the steel wire rope or chain to lift or pull heavy objects vertically, horizontally, or at an angle. Winches can be classified into three types: hand-operated, electric, and hydraulic, with electric winches being the most common.

[0025] The role of winches: Winches play an important role in many fields, which can be seen in the following aspects:

[0026] Lifting and moving goods: The main function of a winch is to lift and move goods. In construction sites, it is often used to lift building materials, decoration materials, tools, etc.; in ports, it is used to unload, load, and transport containers; in coal mines, it is used to lift coal and transport equipment. In addition, in stage performances, winches are also used to lift devices, sound, and lighting equipment.

[0027] Improving work efficiency: The use of winches can greatly improve work efficiency, reduce labor costs, and reduce labor intensity. Through mechanized operation, winches can quickly and accurately complete the lifting and moving tasks of heavy objects, thereby saving a lot of manpower and time.

[0028] Ensuring the safety of goods: Winches can maintain the stability and safety of goods during lifting and moving. Through reasonable structural design and precise control systems, winches can ensure that goods do not slip or tilt during lifting and moving, thereby avoiding accidents.

[0029] Strong adaptability: Winches have strong adaptability and can be applied to different environments and occasions. Whether in a small space or in a complex environment, winches can perform their lifting and pulling functions. In addition, winches can be customized and modified according to user needs.

[0030] A hydraulic rod is a device that uses hydraulic principles to complete mechanical movements, also known as a support rod, hydraulic cylinder, or hydraulic jack. Its basic working principle is that under the action of a liquid medium, by changing the volume of some devices, a pressure difference is generated, thereby pushing the piston to move and achieving the work of the rod. Specifically, when hydraulic oil is pressurized by a hydraulic pump, it will flow into the hydraulic cylinder or hydraulic motor along the pipeline, pushing the piston or vane to move. The movement of the piston or vane will convert hydraulic energy into mechanical energy, thereby driving or controlling the load. Hydraulic rods are widely used in engineering machinery, aerospace, marine engineering, port machinery, automobile industry, machine tool industry, metallurgical industry, and other fields.

[0031] Hydraulic rods offer advantages such as simple structure, high reliability, and smooth, adjustable movement. Their elastic force can be adjusted by setting different nitrogen pressures or piston rod diameters. Compared to mechanical springs, hydraulic rods have a near-linear elastic curve, resulting in superior performance and adaptability in many applications.

[0032] Furthermore, hydraulic rods can be customized and modified to meet the needs of different users. For example, a protective sleeve can be added to the outside of the hydraulic rod to protect it from dust and moisture corrosion, thereby extending its service life.

[0033] In summary, hydraulic rods are powerful and versatile transmission devices that play an important role in various fields.

[0034] A water pump, also known as a pumping machine, is a mechanical device used to extract liquids (mainly water) and transport them to another location. It uses power generated by an electric motor or other power source to draw liquid from a low point or container through a mechanical structure (such as an impeller or piston) and transport it along pipelines to the desired location.

[0035] Water pumps are widely used in various fields such as agricultural irrigation, urban water supply, industrial drainage, fire fighting, and ship drainage. Their main function is to solve the problem of liquid transportation, especially when it is necessary to lift liquid from a low place to a high place, where the role of water pumps is particularly prominent.

[0036] Depending on their working principle and structure, water pumps can be classified into various types, such as centrifugal pumps, axial flow pumps, mixed flow pumps, piston pumps, and screw pumps. Different types of water pumps also differ in performance, applications, and price. Users can choose the appropriate type of water pump based on their actual needs.

[0037] In general, water pumps are an important liquid transportation device. Their emergence has greatly improved the efficiency and convenience of liquid transportation, bringing great convenience to people's production and life.

[0047] Further, the clamping assembly comprises a fixed frame 21 fixedly connected to the beam of the supporting plate 20, a hydraulic rod 22 horizontally connected to the fixed frame 21, and a clamping piece 23 connected to the extension end of the hydraulic rod 22, wherein the clamping piece 23 is arc-shaped and matched with the sliding rod.

[0048] By controlling the synchronous extension and retraction of the two hydraulic rods 22, the extension end of the hydraulic rod 22 drives the clamping pieces 23 to approach each other towards the sliding rod 9, thereby clamping and fixing the sliding rod 9.
