Description

Technical field:

[0001] The utility model relates to the technical field of in-pit drilling equipment, in particular to a winch protection device based on in-pit drilling. Background technology:

[0002] Tunnel drilling is the application of ground drilling technology to drilling operations in tunnels. Its main purposes are: to explore the structure of the surrounding rock, reveal the occurrence of the ore body, detect groundwater and gas in advance in mining tunnels, discover blind ore bodies, replace certain exploration tunnels or guide the direction of tunnel excavation. During specific operations, it is necessary to cooperate with the winch to lift the core tube. When the core is extracted, mud and oil will be discharged, causing environmental pollution at the construction site. At the same time, the mud sticks to the wire rope. The mud is drawn into the rotating drum of the winch along with the wire rope, causing the winch to wear out and the wire rope to break easily. Once the wire rope breaks, if the winch does not stop working in time, the wire rope will be thrown out, which is easy to cause injury accidents and pose a major safety hazard. Utility model content:

[0003] The utility model aims to provide a winch protection device based on pit drilling to solve the technical problem in the prior art that mud contaminates the steel wire rope during tunnel drilling winch operation, causing the steel wire rope to easily wear and break, posing a safety hazard.

[0004] The content of the utility model: It includes a winch, wherein a protective cover is provided on the outer cover of the drum of the winch, wherein the protective cover is used to prevent the steel wire rope of the winch from being thrown out when it breaks, and a steel wire rope cleaning assembly is installed on the protective cover, wherein the steel wire rope cleaning assembly is used to clean mud on the steel wire rope.

[0005] Furthermore, a connecting shaft is horizontally connected to the frame of the winch, a sleeve is mounted on the connecting shaft, and limit disks are installed at both ends of the sleeve. The wire rope passes under the sleeve and is connected to the movable pulley upward.

[0006] Furthermore, a bearing is installed outside the sleeve.

[0007] Furthermore, the wire rope cleaning assembly includes a cleaning pipe, which is vertically mounted on the wire rope, the cleaning pipe is connected to the protective cover, a compressed air pipeline is connected to the cleaning pipe, an air valve is installed on the compressed air pipeline, and the compressed air pipeline is used to blow away the mud on the wire rope.

[0008] Furthermore, a ring plate is installed at the bottom of the cleaning pipe, the inner hole of the ring plate is clearance-matched with the steel wire rope, and a sewage pipe is connected to the ring plate obliquely downward.

[0009] Furthermore, an annular groove is provided on the annular plate, and the annular groove is connected to the sewage pipe.

[0010] The beneficial effects of the utility model are as follows: the utility model has a simple structure, and a pneumatic blowing mud cleaning device is designed on the wire rope of the winch, which can clean the mud on the wire rope in time, avoid the wire rope driving the mud into the drum, reduce the friction of the wire rope, and increase the service life of the wire rope. At the same time, a protective cover is designed on the winch drum to effectively prevent the wire rope from being thrown out and injuring people when it breaks, thereby avoiding the occurrence of safety accidents.

[0013] Figure 3 for Figure 2 A schematic diagram of the enlarged structure of part A;

[0014] Figure 4 This is the installation structure of the compressed air pipeline of the utility model;

[0015] In the figure, winch 1, wire rope 2, frame 3, connecting shaft 4, limit plate 5, sleeve 6, bearing 7, cleaning pipe 8, compressed air pipeline 9, sewage pipe 10, annular groove 11, protective cover 12, ring plate 13, movable pulley 14. Specific implementation method:

[0016] like Figure 1 As shown, it includes a winch 1, and a protective cover 12 is provided on the outer cover of the drum of the winch 1. The protective cover 12 is used to prevent the wire rope 2 of the winch 1 from being thrown out when it breaks. A wire rope cleaning assembly is installed on the protective cover 12, and the wire rope cleaning assembly is used to clean the mud on the wire rope 2.

[0017] like Figure 2 As shown, a connecting shaft 4 is horizontally connected to the frame 3 of the winch 1, a sleeve 6 is mounted on the connecting shaft 4, and limit plates 5 are installed at both ends of the sleeve 6. The wire rope 2 passes through the bottom of the sleeve 6 and is upwardly connected to the movable pulley 14; in order to further reduce the friction of the wire rope 2, a bearing 7 is installed outside the sleeve 6.

[0018] like Figure 3 and Figure 4As shown, the wire rope cleaning assembly includes a cleaning pipe 8, which is vertically sleeved on the wire rope 2, and the cleaning pipe 8 is connected to the protective cover 12. A compressed air pipeline 9 is connected to the cleaning pipe 8, and an air valve is installed on the compressed air pipeline 9. The compressed air pipeline 9 is used to blow away the mud on the wire rope 2; an annular plate 13 is installed at the bottom of the cleaning pipe 8, and the inner hole of the annular plate 13 is clearance-fitted with the wire rope 2, and a sewage pipe 10 is connected to the annular plate 13 obliquely downward; an annular groove 11 is opened on the annular plate 13, and the annular groove 11 is connected to the sewage pipe 10.

[0019] like Figures 1 to 4 As shown, when the winch 1 is hoisting the drilling core tube, it is inevitable that magma and the like will stick to the wire rope 2. The air valve is opened to allow the compressed air pipeline 9 to blow the wire rope 2, and the mud is blown down and splashed on the inner wall of the cleaning tube 8. The mud flows into the annular groove 11 due to its own gravity and is discharged through the sewage pipe 10. If the wire rope 2 breaks after a long period of use, due to the obstruction of the protective cover 12, even if the winch 1 is not stopped in time, the wire rope 2 will not be thrown out and cause an injury accident.

[0020] The above are only preferred examples of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
