[0022] The utility model is further described in detail below in conjunction with the embodiments.

[0023] An alarm type large mine car material box shock absorbing device, such as Figure 1 , including a main body 7, a fixing seat 4 arranged at the periphery of the main body 7, a proximity switch 5 installed on the upper end surface of the main body 7, and an alarm device 6 electrically connected to the proximity switch 5 through a wire. The main body 7 is installed on the upper end surface of the large mining car frame through the fixing seat 4.

[0024] The main body 7 includes three layers of wear-resistant plates, a rubber pad 2 arranged between the upper and middle wear-resistant plates, and a spring group 3 ( Figure 1 The dotted circle in the middle is the spring group 3), the fixing seat 4 is located on the lower wear-resistant plate, and the proximity switch 5 is located on the side wall of the upper wear-resistant plate.

[0025] The wear-resistant plate is a manganese steel plate 1, and its thickness is 4~6mm, and it can also be other thicknesses, which are selected according to specific circumstances.

[0026] The thickness of the rubber pad 2 is 12-20 mm, preferably 15 mm, and the thickness of the rubber pad 2 is greater than the length of the spring group 3, and the length of the spring group 3 is preferably 5-8 mm. Figure 2 shown.

[0027] exist Figure 1 , Figure 2 In the embodiment, the fixing seat 4 is located at the four corners of the lower manganese steel plate 1 in the main body 7. The fixing seat 4 is trapezoidal, with a waist-shaped hole in the center, and is connected to the upper end surface of the large mining car frame by M14 bolts. The proximity switch 5 is a KSC02 proximity switch, and the alarm device 6 is a buzzer, which is sensitive and has a good alarm effect.

[0028] In order to improve the use effect of the spring group 3, the patent also improves the spring group 3, such as Figure 4 It is shown that the spring group 3 includes a plurality of coil springs 31, connecting plates 32 arranged at the upper and lower ends of the coil spring 31, and a telescopic column 33 located between the upper and lower connecting plates 32. The connecting plate 32 is used to be installed between two adjacent layers of wear-resistant plates, and the two adjacent connecting plates 32 on the left and right can also be connected together. The telescopic column 33 is a sleeve-type telescopic column made of metal material, and the overall structure is thin at the top and thick at the bottom, and the upper sleeve is inserted into the lower sleeve. The telescopic range of the telescopic column 33 is between the elastic extremes of the coil spring 31, which can protect the coil spring 31 from irreversible elastic deformation. The telescopic column 33 welded at the center of the connecting plate 32 can also make the coil spring 31 deform along the axial direction, try to avoid spring dislocation, and improve the telescopic effect of the spring.

[0029] The rubber pad 2 and spring group 3 of the device can effectively play a shock-absorbing role. Since the KSC02 type proximity switch is installed on the upper end face of the device, when the rubber pad 2 and spring group 3 of the device are aged and cannot play a shock-absorbing role, the proximity switch 5 triggers an alarm and reminds you to replace them, thereby avoiding deformation and damage of the frame and the material box.

[0030] The overall installation effect is as follows Figure 3As shown, the device acts as a buffer between the material box and the frame of the mine car, reducing deformation and damage caused by collision between the material box and the frame. Because it is installed below the material box, about 6 meters from the ground, the unique alarm device 6 can reduce the daily inspection of the staff on duty and avoid the occurrence of high-altitude falling accidents.
