Abstract
Description
Technical Field
[0001] This utility model relates to the field of mining equipment technology, and in particular to a buffer deceleration device for mining locomotives. Background Technology
[0002] Mining cars are important assets for mining companies. When a mining car exits the cage at the secondary shaft entrance, a pusher is used to push it out onto a rocking platform on the other side. Due to the height difference between the rocking platform and the track at the exit end, as well as the slope of the track itself, the mining car will move along the track to the yard by its own potential energy after exiting the cage. However, because the pusher has a large pushing force, the impact force between mining cars is also large, which can easily damage the car bumper and cause economic losses. Utility Model Content
[0003] To address the aforementioned technical problems, this utility model provides a buffer deceleration device for mining locomotives.
[0004] To achieve the above objectives, the technical solution of this utility model is as follows:
[0005] A buffer reduction device for mining locomotives, comprising:
[0006] The base plate is fixedly installed on one side of the track;
[0007] Several spring cavities are vertically arranged on the base plate, and springs are installed inside them;
[0008] The pressure rod is fitted into the spring cavity at its bottom and contacts the spring.
[0009] The fixing plate is horizontally fixed to the top of the pressure bar and corresponds to the position of the wheel axle of the mining locomotive.
[0010] The top of the spring cavity is provided with a spring cavity cover, and the spring cavity cover is provided with a through hole for mounting the pressure rod.
[0011] The upper surface of the fixing plate is provided with a rubber buffer surface.
[0012] The base plate is provided with a tightening seat, which has a vertical screw hole. The fixing plate is provided with mounting holes corresponding to the tightening seat. Bolts pass through the mounting holes and are installed on the screw holes of the tightening seat.
[0013] The end of the pressure rod installed inside the spring cavity has a ball-shaped structure.
[0014] The beneficial effects of this utility model are:
[0015] 1. This utility model can flexibly impede and buffer the collision force of mine cars, allowing them to slow down gradually and reducing the possibility of damage. The buffer device is made of flexible materials, extending the formation and time of the collision force release, reducing collision displacement, and preventing derailment and overturning. Furthermore, this utility model is ingeniously designed, simple in structure, and easy to manufacture, making it highly valuable for widespread application.
[0016] 2. This invention uses four springs and corresponding pressure rods to buffer the impact force from the mine car. Considering the limited force reduction of the springs, multiple devices can be arranged along the route as needed. To prevent damage to the mine car from excessive impact force, the impact surface between this invention and the mine car is made of rubber. Considering the need for spring replacement, this invention uses a spring cavity to fix the springs for easy replacement.
[0017] 3. This utility model uses anchor bolts to fix it in the middle of the track. Considering that manual pushing is required in actual production, this device can use bolts to press down the fixing plate.
[0018] 4. The spring described in this utility model, as the main buffer element, can undergo elastic deformation when subjected to external impact, absorbing and dispersing energy, thereby slowing down the mine car. The spring has a suitable elastic coefficient to ensure good buffering effect under different impact forces. The rubber buffer surface, located at the position in direct contact with the mine car, is a replaceable component. The rubber material has good flexibility and wear resistance, which can better protect the mine car and prevent damage to its surface during collisions. At the same time, the rubber buffer surface will deform to a certain extent when compressed, further enhancing the buffering effect. The spring cavity is used to house the spring, providing a stable working space for the spring and preventing the spring from shifting or twisting during force application. The inner wall of the spring cavity is smooth to reduce friction between the spring and the cavity wall, improving the service life of the spring. The spring cavity cover is installed at the opening of the spring cavity, serving to seal and fix the spring. It can prevent dust, debris, etc. from entering the spring cavity and affecting the normal operation of the spring. The tightening seat, used in conjunction with other components, achieves fixation and height adjustment of the entire device through the connection of bolts to the tightening seat. The tightening seat possesses sufficient strength and stability to withstand significant tensile and compressive forces. The pressure rod utilizes a ball-head spring design, with the ball head contacting one end of the spring. This design ensures that when pressure is applied, the force is evenly distributed to the spring, preventing excessive localized stress and damage. Simultaneously, the ball-head structure helps prevent the device's fixing plate from tipping over during impact, ensuring the stability of the cushioning effect. The fixing plate secures the rubber cushioning surface, facilitating its replacement and repositioning, and is connected to the base plate via the pressure rod. Bolts and other fasteners connect the tightening seat to other components, allowing for height adjustment. Tightening or loosening the bolts changes the height of the compression device. Other fasteners secure the connections between components, ensuring the overall stability of the device. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.
[0027] like Figures 1 to 4 As shown, a buffer deceleration device for a mining locomotive includes: a base plate 1, fixedly installed on one side of the track; several spring cavities 2, vertically arranged on the base plate 1, each containing a spring 9; a pressure rod 5, fitted at the bottom within the spring cavities 2 and in contact with the springs 9; and a fixing plate 6, horizontally fixed to the top of the pressure rod 5 and corresponding to the wheel axle position of the mining locomotive. A spring cavity cover 3 is provided on the top of each spring cavity 2, and the spring cavity cover 3 has a through hole for mounting the pressure rod 5. A rubber buffer surface 7 is provided on the upper surface of the fixing plate 6. A tightening seat 4 is provided on the base plate 1, and the tightening seat 4 has a vertical screw hole. The fixing plate 6 has mounting holes corresponding to the tightening seat 4, and bolts 8 pass through the mounting holes and are mounted on the screw holes of the tightening seat 4. One end of the pressure rod 5 installed within the spring cavity 2 has a ball-shaped structure.
[0028] like Figure 4 and Figure 5 As shown, in use, the mine car is pushed by the pusher and impacts the device, where the spring compression generates a counterforce to slow down the mine car. After the impact, the mine car axle rubs against the rubber buffer surface 7. The mine car (A) is pushed out by the pusher and impacts the rubber buffer surface 7, where the spring 9 is compressed to generate a reaction force to slow down the mine car. Considering that the device fixing plate 6 may overturn during the impact, the compression spring device is designed with a ball head shape, and sufficient clearance is left between the compression rod 5 and the spring cavity cover 3 to prevent damage to the device.
[0029] Since manual pushing of mine carts is required during mining operations, this invention provides a compression device to prevent the device from contacting the mine carts during manual pushing, such as... Figure 2 , Figure 5 As shown, when manual pushing is required, bolts 8 and tightening seat 4 are used to press the device tight. Since the bolts will protrude from the base plate 1 when tightening, a pit needs to be dug under the tightening seat 4 during installation.
[0030] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
