Abstract
Description
Technical Field
[0001] This utility model relates to the field of coal mine electromechanical equipment testing technology, and in particular to a coal mine electromechanical hoist testing device. Background Technology
[0002] Coal mine electromechanical hoists are core and critical equipment in coal mine production. They are mainly used for the vertical transportation of personnel, materials, and coal underground. Their operational stability and safety are directly related to the efficiency of coal mine production and the safety of workers.
[0003] The Chinese Patent Network discloses a coal mine hoist for preventing tipping, with publication number CN216038104U. Although this coal mine hoist for preventing tipping uses anti-loosening wheels under the baffle to limit and guide the steel cable on the outside of the guide roller to prevent accidental deviation and detachment of the steel cable, and when the coal moves up the mine shaft to a designated height at the shaft opening, the hydraulic rod pulls the steel cable to drive the coal container to unload in a designated direction, and when the hoist is powered off, the limiting strip on the outside of the rotating disc presses against the top of the limiting block in the opposite direction, thus preventing the hoist's rollers from reversing and causing operational accidents in the event of a power outage, the steel cable may still deviate or even detach during the long-term high-intensity operation of the coal mine hoist. If it is not detected and dealt with in time, it can easily lead to a major safety accident.
[0004] To address the aforementioned technical deficiencies, a solution is proposed. When the steel cable deviates, it will squeeze and touch one of the moving rods. At this time, the moving rod will move outward. When the contact plate of the moving rod contacts the contact switch, it will trigger the contact switch. The contact switch will send a signal to the controller, which will then activate the alarm installed in the control center of the coal mine electromechanical hoist. Therefore, this invention can immediately alert workers that the steel cable may have deviated, enabling workers to promptly inspect and handle the steel cable, thus preventing safety accidents. Utility Model Content
[0005] The purpose of this invention is to provide a testing device for coal mine electromechanical hoists to solve the problems mentioned above.
[0006] The objective of this utility model can be achieved through the following technical solution: a detection device for a coal mine electromechanical hoist, comprising: Install components; The installation assembly includes a connecting seat, and a U-shaped seat is fixed to the bottom of the connecting seat.

[0012] The beneficial effects of this utility model are: 1. When the steel cable deviates, it will squeeze and touch one of the moving rods. At this time, the moving rod will move outward. When the contact plate of the moving rod contacts the contact switch, it will trigger the contact switch. The contact switch will send a signal to the controller, and the controller will then activate the alarm installed in the control center of the coal mine electromechanical hoist. Therefore, this utility model can remind the staff that the steel cable may deviate in time, so that the staff can inspect and deal with the steel cable in time and avoid the occurrence of safety accidents. When the contact plate contacts the contact switch, the contact switch will retract accordingly to avoid excessive contact between the contact plate and the contact switch, which could cause damage due to excessive pressure. This ensures the working efficiency and service life of the contact switch. Furthermore, when the contact switch contacts the contact plate, under the action of the second spring, the telescopic rod and the moving plate drive the contact switch to make tight contact with the contact plate, thereby ensuring the triggering effect of the contact switch and thus ensuring the detection accuracy of the steel cable.
[0013] 2. By using tools to remove the fixing bolts, the fixing of the connecting seat and the coal mine electromechanical hoist can be released. Then, the connecting seat can be disassembled, and the connecting ring can be rotated to separate it from the outer wall of the threaded column, thereby releasing the fixing of the connecting seat and the inner ring seat. The connecting seat and the inner ring seat can then be disassembled and separated, which facilitates the cleaning and regular maintenance of the contact switch, ensuring the working efficiency and service life of the contact switch, and further ensuring the detection accuracy of the steel cable.
