Description

Technical Field

[0001] The utility model relates to the field of mining machinery and equipment, in particular to a narrow-track magnetic wedge device for mining. Background Art

[0002] In the process of coal mining and transportation, narrow-gauge railways are important channels for the transportation of mining vehicles. Due to the special characteristics of the coal mine environment, such as complex terrain, multiple route slopes, high humidity, and high dust, mining vehicles are prone to slide under their own gravity or external forces when parked, leading to safety accidents and seriously threatening the lives of miners. Therefore, how to effectively fix mining vehicles to prevent them from sliding has become an urgent problem to be solved in coal mine safety production.

[0003] Traditional methods of fixing mining vehicles usually rely on manual operation, such as using wooden wedges, stones and other objects to wedge the vehicle. These methods are not only cumbersome and inefficient, but also pose great safety hazards. For example, in an emergency, manual operation may not be able to quickly and effectively fix the mining vehicle. At the same time, during the wedging process, personnel need to be in close contact with the wheels and tracks, which can easily cause accidents such as squeezing and crushing. In addition, the existing wedging device has insufficient friction and adhesion between the wheels and tracks when wedging, resulting in poor fixing effect. Some wedging devices are prone to slipping off the track or overturning when subjected to external forces, and are not stable and safe. Utility Model Content

[0004] The utility model provides a narrow-gauge magnetic wedge device for mining, which aims to stably adsorb vehicles on the track through magnetic force, improve the safety of mining vehicles on coal mine narrow-gauge railways when they are parked, and prevent the vehicles from sliding by themselves.

[0005] To achieve its purpose, the utility model adopts the following technical solutions:

[0006] A narrow-gauge magnetic wedge device for mining comprises a herringbone-shaped wedge part, the wedge part comprises a steel core arranged inside the wedge part, and a plurality of magnets are symmetrically arranged inside the steel core; the bottom of the wedge part is symmetrically connected with flanges in the length direction, a connecting rod is vertically connected to the outer side of any flange, and a handle is connected to the free end of the connecting rod.

[0007] Preferably, the handle is tilted, and its angle with the horizontal direction is 30°-45°.

[0008] Preferably, a pull ring is connected to the free end of the handle.

[0009] Preferably, the outer wall of the pull ring is provided with an anti-slip tube.

[0010] Preferably, the arc of the outer wall of the wedge portion is the same as the arc of the wheel of the mining car.

[0011] Preferably, the outer surface of the wedge portion is subjected to a rubber vulcanization coating treatment.

[0012] Preferably, the magnet is recessed in the steel core, and the distance between the bottom of the magnet and the bottom of the steel core is 2-3 mm.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. The wedge device provided by the utility model adopts magnetic adsorption technology to fix the wedge device on the track, effectively preventing the mine car from slipping or overturning due to external force, and improving the safety of the operation. The setting of the handle can keep the operator's limbs and extremities in a safe position when wedging the car, avoiding the risk of squeezing and crushing fingers caused by close contact with the wheel, further ensuring the safety of the operator, and being easy to operate, greatly reducing the safety hazards and downtime during the operation, and improving the operation efficiency of the parking of coal mine narrow-gauge railway mining vehicles.

[0015] 2. The handle connected to the wedge part of the utility model conforms to the principle of ergonomics, making the process of operating the wedge device easy and stable. In addition, the retaining edge arranged at the bottom of the wedge part stably fixes the wedge device on the track, preventing the occurrence of left and right displacement, greatly simplifying the operation process and improving the working efficiency.

[0016] 3. A high-strength steel core is arranged inside the wedge part of the utility model, and the outer surface of the wedge part is treated with rubber vulcanization coating, which not only improves the friction adhesion and buffering performance between the wheels and rails, but also makes the device have excellent wear resistance and durability, and can adapt to the harsh working environment of coal mines. Moreover, the surface treated with rubber vulcanization coating can reduce the wear on the wheels and rails, extend the service life of the vehicle and rails, and reduce the maintenance cost.

[0023] The utility model is further described below in conjunction with the accompanying drawings:

[0024] like Figure 1-5 As shown, the utility model is a narrow-track magnetic wedge device for mining, including a herringbone-shaped wedge portion 3, the outer wall arc of the wedge portion 3 is the same as the arc of the wheel 7 of the mine car 6, and the outer surface of the wedge portion 3 is rubber-vulcanized and coated to provide better friction adhesion and buffering performance between the wheel 7 and the track 8, ensuring stable parking of the vehicle. The wedge portion 3 includes a high-strength steel core arranged inside it, and two strong magnets 5 are symmetrically arranged in the steel core. The magnets 5 are recessed in the steel core, and the distance between the bottom of the magnet 5 and the bottom of the steel core is 2mm, ensuring that the magnets 5 will not be damaged when subjected to force. The magnetic force generated by the magnets 5 firmly adsorbs the wedge device on the track 8 to prevent it from slipping or overturning due to external forces. The bottom of the wedge portion 3 is symmetrically connected to the ribs 4 in the length direction, and a connecting rod 2 is vertically connected to the outside of any rib 4. The free end of the connecting rod 2 is connected to a handle 1, which is made of aluminum alloy and is light and durable. The handle 1 is tilted, and its angle with the horizontal direction is 45°. The handle 1 conforms to the principle of ergonomics, which is convenient for the operator to hold and stably control the wedge device, and ensures that the operator's limbs and extremities are in a safe position when using it. The free end of the handle 1 is connected to a pull ring 10, and the outer wall of the pull ring 10 is covered with an anti-slip tube, which increases the stability of the operator when holding it and avoids sliding or falling out of the hand during operation.

[0025] When a wedge is needed, the operator holds the handle 1 and places the magnetic climbing wedge device stably on the track. At this time, the magnet in the steel core generates an adsorption force to quickly fix the wedge device on the track. To ensure that the mine car does not slide on its own, it is necessary to manually apply pressure between the wedge device and the wheel 7 so that the wedge part 3 is in close contact with the wheel 7 to enhance the wedge effect. The outer surface of the wedge part 3 is treated with rubber vulcanization and rubber coating, which can provide sufficient friction and caching performance to ensure stable parking of the vehicle. When the vehicle needs to be moved, the operator holds the handle 1 and gently lifts the wedge device to easily remove it from the track.
