Description

Technical Field

[0001] The utility model relates to the technical field of mining installation equipment, in particular to a protective device for a race car in an inclined shaft. Background Art

[0002] Inclined shaft runaway protection devices are used to prevent runaway accidents during inclined shaft hoisting, ensuring the safety of workers. They also protect mine cars from damaging equipment such as railings during high-speed lowering. Inclined shaft runaway protection devices typically involve the coordinated operation of position sensors, control boxes, and railings. When a mine car is traveling at normal speed, the railings are open, allowing the car to pass. If a mine car runs away due to a broken rope, unhooking, or other reasons, the railings quickly close, intercepting the car and preventing it from continuing to slide down and causing an accident.

[0003] For example, the inclined shaft runaway car protection device disclosed in the existing patent announcement number CN205769328U includes a monitoring area and a transmission execution area arranged in the coal mine inclined shaft. The monitoring area is located on the upper end plane of the coal mine inclined shaft, and the transmission execution area is located at the lower end of the coal mine inclined shaft. An operating console, a PLC controller and a rotary encoder are provided in the monitoring area, and a position sensor, an electromagnetic starter, a car block and a mounting frame are provided in the transmission execution area. If the runaway car occurs due to rope breakage, unhooking, etc., a buffer can be used to achieve effective interception. When the mine car is not working, the inclined shaft runaway car protection device is in a locked state.

[0004] The above device can protect the runaway car in the inclined shaft when in use, but the connection between adjacent rope pulleys is loose, its protection stability effect still needs to be improved, and the adjacent adjustment is relatively inconvenient, and its practicality still needs to be improved. In response to the above problems, a device for protecting the runaway car in the inclined shaft is proposed. Utility Model Content

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] See also Figure 1-Figure 5 In this embodiment, a protection device for a car in an inclined shaft includes a retractable winch 1 installed in the inclined shaft and a pressure plate buffer 7 installed on both sides of the track;

[0031] It also includes a positioning slot steel frame 3 installed in the inclined shaft, a vehicle blocking structure 5 is provided at the bottom of the positioning slot steel frame 3, a retractable wire rope 2 is installed on the retractable winch 1, and a pulley 4 for the retractable wire rope 2 to pass through is installed at the bottom of the positioning slot steel frame 3;

[0032] The vehicle blocking structure 5 includes a mounting rod 501 and a vehicle blocking fence 502 connected to the bottom of the mounting rod 501. The mounting rod 501 is connected to the retractable wire rope 2. A plurality of protective tubes 503 are provided on one side of the vehicle blocking fence 502. The vehicle blocking fence 502 is provided with a fixed pressure plate 506 for fixing the protective tubes 503. The vehicle blocking fence 502 is connected to a fixing piece for fixing the fixed pressure plate 506.

[0033] After the barrier 502 is lifted into place, the distance from the track surface is greater than the height of the object passing through;

[0034] Two sets of connecting chains 505 are connected between adjacent protective tubes 503. Buffer steel wire ropes 6 pass through the protective tubes 503. Both ends of the buffer steel wire ropes 6 are connected to the pressure plate buffers 7. The buffer steel wire ropes 6 can be pressed and installed on the bottom of the pressure plate buffer 7.

[0035] When the mine car runs to the designated position, the retractable winch 1 adjusts the retractable wire rope 2 to reel in the wire, and the adjustable car-blocking structure 5 is raised (opened). After the mine car passes and reaches the set position, the car-blocking structure 5 falls (closes). When the mine car encounters situations such as running away, slipping, tripping, and rope breaking, the device can reliably intercept the mine car to avoid accidents.

[0036] The buffer steel wire rope 6 serves as an auxiliary fixing and reinforcing structure. By closely cooperating with the car barrier 502, it ensures that the sports car can be fixed when it is impacted, preventing it from crossing the car barrier 502. It can also achieve a certain buffering effect, reducing the impact of the sports car when it is impacted, and the protective tube 503 can partially protect the buffer steel wire rope 6, reducing the wear of the buffer steel wire rope 6 during the protection of the sports car.

[0037] like Figure 1 As shown, one side of the retractable winch 1 is provided with a control box 11 and an audible and visual alarm 12 installed in the inclined shaft; the control box 11 and the audible and visual alarm 12 are installed in a place without dripping water.

[0038] The fixing parts include fixing bolts, and the vehicle barrier 502 is provided with screw holes that cooperate with the fixing bolts, and both ends of the fixed pressure plate 506 are provided with through holes that cooperate with the fixing bolts; the fixing bolts can be used to fix the position of the fixed pressure plate 506. In actual use, the number and installation position of the fixed pressure plate 506 can be adjusted according to the number and installation position of the protective tubes 503 to facilitate the installation of the protective tubes 503; the position of the protective tube 503 is adjustable, and the layout position of the protective tube 503 and the buffer wire rope 6 can be adjusted according to the layout of the mine car to further enhance the protection effect.

[0039] One side of the bottom of the vehicle barrier 502 is connected to a pull ring 507 to facilitate subsequent dragging of the vehicle barrier 502.

[0040] The protective tube 503 is connected to a hanging ring 504; multiple protective tubes 503 can be connected by a connecting chain 505. When the vehicle barrier 502 is not in use, the retractable wire rope 2 can also be connected to the hanging ring 504, thereby improving the applicability of the device.

[0041] like Figure 1 and Figure 4 As shown, a winch drum 9 is installed at one end of the track, and a mine car cable 8 connected to the mine car is wound around the winch drum 9. The shaft end of the winch drum 9 is connected to the drum central axis 901. One end of the drum central axis 901 is provided with a mine intrinsically safe position sensor 902. The end of the drum central axis 901 away from the mine intrinsically safe position sensor 902 is provided with a mine intrinsically safe shaft encoding sensor 903.

[0042] The intrinsically safe shaft encoding sensor 903 for mining can be used to detect the lifting and lowering distance of the mine car. The intrinsically safe position sensor 902 for mining is an existing counting sensor. The sensors are used side by side in a group of two with a spacing (center to center) of no more than 22 mm. They are fixed on the static seat of the reducer output shaft, and the magnet is attached to the drum center axis 901. The distance between the front end face of the sensor and the magnet is approximately 3 to 4 mm. After the sensor wiring is completed, the operating box 10 is powered on and the magnet is aligned with the sensor probe. The indicator light at the sensor output end will light up. If it does not light up, please check whether the polarity of the magnet is correct.

[0043] An operation box 10 is provided on one side of the winch drum 9; the operation box 10 is installed in a place where there is no dripping water.

[0044] The bottom of the pressure plate buffer 7 is crimped to a fixed steel wire rope 701 , and the fixed steel wire rope 701 is connected to a plurality of rope clips.

[0045] The working principle of the utility model is as follows: when the winch is operating normally and the mine car reaches the set position, the car blocking structure 5 rises (opens); after the mine car passes and reaches the set position, the car blocking structure 5 falls (closes). When the mine car encounters situations such as running away, slipping, tripping, and rope breaking, the device can reliably intercept the mine car to avoid accidents.

[0046] This device can be installed and used in all single-track or double-track lifting and transportation inclined tunnels with an inclination angle of less than 30° in coal mines, metal mines, non-metallic mines, etc., to ensure the safety of inclined tunnel lifting and prevent various runaway accidents.
