[0029] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0030] like Figures 1-3As shown, a high-strength mining cab includes a body 1, which is formed by a frame and skin. A base plate 2 and a reinforcing mechanism mounted on the base plate 2 are provided on the outer wall of the body 1. The reinforcing mechanism includes a reinforcing plate 31, a shock-absorbing spring 32, and a diagonal brace 33. The reinforcing plate 31 is inverted L-shaped, with its horizontal end located above the body 1 and its vertical end located behind the body 1. The base plate 2 on the outer wall of the body 1 effectively improves the strength of the body 1. Furthermore, under the support of the base plate 2, the reinforcing mechanism can be in a predetermined working state, thus reliably strengthening the overall strength of the body 1. Specifically, when a rolling stone falls from above the body 1, the horizontal end of the reinforcing plate 31 will bend, and the metal of the reinforcing plate 31 itself will... The combination of the toughness and the compression and rebound of the shock-absorbing springs buffers the falling stones, preventing direct hard collisions between the stones and the top of the main body 1, thus avoiding damage to the main body 1. When the stones fall obliquely towards the front of the main body 1, the impact of the stones on the vertical end of the reinforcing plate 31 causes the equally tough inclined support 33 to undergo elastic deformation, thus buffering the impact. Because the inclined support 33 is obliquely positioned, the vertical end of the reinforcing plate 31 can deform more easily when impacted, thereby achieving buffering. The probability of impact on the vertical end of the reinforcing plate 31 and the energy after impact are both less than those on the horizontal end of the reinforcing plate 31. Thus, by using the inclined support 33 to support the vertical end of the reinforcing plate 31, the overall connection strength can be improved to a certain extent.

[0031] The shock-absorbing spring 32 is disposed between the horizontal end of the reinforcing plate 31 and the base plate 2. Multiple limiting blocks 34 are provided on the reinforcing plate 31 and on the outside of the shock-absorbing spring 32. The height of the limiting blocks 34 is greater than the length of the shock-absorbing spring 32 after it is fully compressed. The limiting blocks 34 are used to limit the horizontal end of the reinforcing plate 31 to prevent the horizontal end of the reinforcing plate 31 from bending too much and breaking.

[0032] One end of the diagonal brace 33 is fixedly connected to the base plate 2, and the other end of the diagonal brace 33 abuts against the vertical end of the reinforcing plate 31;

[0033] The horizontal end of the reinforcing plate 31 and the vertical end of the reinforcing plate 31 are provided with several connecting seats 4 for fixing and connecting the reinforcing plate 31 and the base plate 2. By connecting the reinforcing plate 31 and the base plate 2 through multiple spaced connecting seats 4, it is ensured that both the horizontal and vertical ends of the reinforcing plate 31 can rotate and deform around the area formed by the connecting seats 4, thereby reliably buffering the impact of rolling stones and improving the overall strength and safety protection capability of the body 1.

[0034] The height of the limiting block 34 increases from the front to the rear of the body 1. In this way, after the bending amplitude of the horizontal end of the reinforcing plate 31 reaches the limit value, the limiting blocks 34 at different positions can contact the top of the base plate 2, thereby simultaneously realizing the limiting function.

[0035] The height of one end of the inclined support 33 is greater than the height of the other end of the inclined support 33. That is, the inclined support 33 is inclined downward toward the rear side of the main body 1, so that when it is hit downward toward the front side of the main body 1, it can avoid vertical impact and promote the deformation of the inclined support 33 to provide cushioning.

[0036] The base plate 2 is fixedly provided with a plurality of pads 35 corresponding one-to-one with a plurality of diagonal braces 33. One end of each diagonal brace 33 is welded to a pad 35, and the other end of each diagonal brace 33 is attached to a reinforcing plate 31. The pads 35 are used to install the diagonal braces 33, thereby improving the installation firmness of the diagonal braces 33.

[0037] The connecting seat 4 includes a connecting block 41 and a pressure rod 42. One end of the connecting block 41 is fixedly connected to the base plate 2, and the other end of the connecting block 41 supports the reinforcing plate 31.

[0038] The pressure rod 42 has a T-shaped cross-section. The horizontal end of the pressure rod 42 presses against the outer wall of the reinforcing plate 31, and the vertical end of the pressure rod 42 passes through the reinforcing plate 31, the connecting block 41, and the base plate 2 in sequence. The pressure rod 42 and the connecting block 41 are interference-fitted. Through the interference fit between the pressure rod 42 and the connecting block 41, the other end of the reinforcing plate 31 and the connecting block 41 are tightly fitted together. Then, one end of the connecting block 41 is fixedly connected to the base plate 2, thereby achieving a reliable connection between the base plate 2, the connecting block 41, and the reinforcing plate 31, ensuring that the reinforcing plate 31 can only bend and will not have overall displacement in the horizontal or vertical directions. The T-shaped cross-section of the pressure rod 42 can better lock the connecting block 41 and the reinforcing plate 31.

[0039] The reinforcing plate 31 has a first through hole 310, the connecting block 41 has a second through hole 410, and the base plate 2 has a third through hole 20. The first through hole 310, the second through hole 410, and the third through hole 20 are coaxially arranged, and the pressure rod 42 passes through the first through hole 310, the second through hole 410, and the third through hole 20 in sequence. The arrangement of the first through hole 310, the second through hole 410, and the third through hole 20 ensures that the pressure rod 42 can reliably pass through the reinforcing plate 31, the connecting block 41, and the base plate 2, and can achieve an interference fit with the connecting block 41, ultimately achieving a secure installation of the reinforcing plate 31.

[0040] The inner diameter of the first through hole 310 and the inner diameter of the third through hole 20 are the same and larger than the outer diameter of the vertical end of the pressure rod 42, while the inner diameter of the second through hole 410 is smaller than the outer diameter of the vertical end of the pressure rod 42.

[0041] The vertical end of the pressure rod 42 extends to the outside of the third through hole 20, and the portion of the vertical end of the pressure rod 42 located outside the third through hole 20 is connected to the substrate 2 by electric welding. Extending the vertical end of the pressure rod 42 to the outside of the third through hole 20 facilitates welding operations, ensures a firm connection between the vertical end of the pressure rod 42 and the substrate 2, and thus ensures the reliable tensioning effect of the pressure rod 42 on the reinforcing plate 31.

[0042] Both ends of the connecting block 41 are provided with retaining rings 412 that serve as limiting devices. A pair of retaining rings 412 are respectively connected to the base plate 2 and the reinforcing plate 31. The retaining rings 412 are fixedly connected to the reinforcing plate 31 and the base plate 2, which can prevent the connecting block 41 from shifting to a certain extent and enhance the connection strength of the connecting block 41 to the reinforcing plate 31 and the base plate 2.

[0043] A method for producing a high-strength mining cab includes the following steps:

[0044] S1. The substrate 2 is welded to the outer wall of the body 1 by pressure welding, and sealant is applied to the periphery of the substrate 2.

[0045] S2. Mark the mounting positions of the connecting block 41 and the pad 35 on the substrate 2, and then weld the connecting block 41 and the pad 35 to the corresponding marked points.

[0046] S3. The moving reinforcing plate 31 aligns the first through hole 310 with the second through hole 410 and hammers in the pressure rod 42 to achieve the initial fixation of the reinforcing plate 31;

[0047] S4. Weld the pressure bar 42 extending to the outside of the third perforation 20 to the base plate 2 to achieve complete fixation of the reinforcing plate 31.

[0048] The above production method can effectively enhance the strength, robustness, and protective properties of the main body 1, prevent the main body 1 from collapsing, and ensure personnel safety.

[0049] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
