However, the utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to enable a more thorough and complete understanding of the disclosure of this utility model.

[0034] It should be noted that the terms "vertical," "horizontal," "up," "down," "left," "right," and similar expressions used in this article are for illustrative purposes only and do not represent the only possible implementation.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0036] like Figures 1 to 12 As shown, this application provides a fall prevention braking device for an inclined shaft transport vehicle, including an inclined shaft transport vehicle 100 and an inclined shaft track 200. The inclined shaft transport vehicle 100 slides on the inclined shaft track 200. It also includes a braking assembly 300 movably disposed inside the inclined shaft. The braking assembly 300 is located above the inclined shaft track 200 on the same vertical plane. The braking assembly 300 includes a three-level protective plate assembly 310 and a protective steel wire rope assembly 320.

[0037] The three-level protective plate assembly 310 includes a vertical protective frame 311, the top of which is movably connected to the top of the inner wall of the inclined shaft, and the lower end of the protective frame 311 is fixedly connected to the protective wire rope assembly 320. The protective frame 311 can be retracted to the top of the inner wall of the inclined shaft by a power component 330.

[0038] The protective wire rope assembly 320 is located on the protective frame 311 on one side of the upper inclined surface near the inclined shaft track 200.

[0039] It should be further explained that by adopting the braking assembly 300, the three-level protective plate assembly 310, and the protective wire rope assembly 320, the falling inclined shaft transport vehicle 100 can be protected by multiple levels, reducing injury and danger, and improving the safety of inclined shaft transportation.

[0040] Specifically, the three-level protective plate assembly 310 also includes protective clamps 312 symmetrically fixed on both sides of the protective frame 311, and a protective wire rope assembly 320 is disposed on the inner side of the two protective clamps 312.

[0041] It should be further explained that the protective clamp 312 can protect the inclined shaft transport vehicle 100 when it collides with the outer sides of the inclined shaft track 200, reducing the risk of the inclined shaft transport vehicle 100 slipping off the surface of the protective wire rope assembly 320 after colliding with it and continuing to collide with the outer sides of the inclined shaft track 200, thus playing a further protective and braking role.

[0042] Specifically, the protective wire rope assembly 320 is fixed to one side of the protective frame 311 by a connecting plate 323;

[0043] The protective wire rope assembly 320 includes a primary wire rope 321 and a secondary wire rope 322. The primary wire rope 321 and the secondary wire rope 322 are spaced apart. The primary wire rope 321 and the secondary wire rope 322 are both formed by a number of longitudinal and transverse wire ropes that are crisscrossed and fixed together. The upper and lower ends of the primary wire rope 321 and the secondary wire rope 322 are respectively fixed to the connecting plate 323.

[0044] It should be further explained that the inclined shaft transport vehicle 100 is protected by primary wire rope 321 and secondary wire rope 322, respectively.

[0045] Specifically, the number of longitudinal wire ropes used in the primary wire rope 321 is less than the number of longitudinal wire ropes used in the secondary wire rope 322, and the number of transverse wire ropes used in the primary wire rope 321 is less than the number of transverse wire ropes used in the secondary wire rope 322.

[0046] It needs to be further explained that, through the above structural design, the primary wire rope 321 first contacts the inclined shaft transport vehicle 100 and provides primary protection against it. The primary wire rope 321 deforms. If the primary wire rope 321 fails to block the movement, the inclined shaft transport vehicle 100 will continue to impact the secondary wire rope 322. The secondary wire rope 322 is denser than the primary wire rope 321, and has a better blocking effect, thus strengthening the blocking effect.

[0047] Specifically, the protective frame 311 has several horizontally arranged openings 3111.

[0048] Specifically, it also includes a stop assembly 400, which includes a stop plate 410 movably connected inside the inclined shaft track 200 and corresponding to the position of the protective frame 311. The stop plate 410 and the side of the protective frame 311 away from the protective wire rope assembly 320 are in contact. The stop plate 410 has a driving member 420, which is used to drive the stop plate 410 to rotate inside the inclined shaft track 200.

[0049] Further details need to be provided: the drive unit 420 adopts an electric telescopic rod, one end of which is hinged to the ground inside the inclined shaft track 200, and the other end of which is hinged to the side of the baffle plate 410; through the design of the baffle assembly 400, the stability of the protective frame 311 can be enhanced, thereby further preventing the inclined shaft transport vehicle 100 from falling and avoiding dangerous situations.

[0050] Specifically, it also includes a receiving groove 500 adapted to the braking assembly 300, which is opened on the top surface of the inner wall of the inclined shaft. The receiving groove 500 is used to store the braking assembly 300, and the power component 330 is located inside the receiving groove 500.

[0051] It should be further explained that: the power component 330 adopts an electric telescopic rod, one end of which is hinged inside the receiving groove 500, and the other end of which is hinged to a connector, which is fixedly connected to the protective frame 311.

[0052] Specifically, it also includes a linkage component 600, which includes an elastic telescopic member 610 fixed to one side of the upper end of the protective frame 311. A pressure sensor 620 is fixed to the top of the inner wall of the receiving groove 500 through a support plate. The elastic telescopic member 610 and the pressure sensor 620 are in contact with each other. The pressure sensor 620 and the driving member 420 are electrically connected.

[0053] It needs to be further explained that as the protective frame 311 falls and gradually becomes vertical, the elastic telescopic component 610 and the pressure sensor 620 come into contact. The pressure sensor 620 receives the pressure and then transmits the signal to the drive component 420. After receiving the signal, the drive component 420 drives the baffle plate 410 to flip, so that the baffle plate 410 can block the protective frame 311 and enhance the stability of the protective frame 311, thereby further blocking the falling inclined shaft transport vehicle 100.

[0054] Specifically, the elastic telescopic member 610 includes a sleeve 611 fixed on the protective frame 311, and an inner rod 612 is slidably sleeved on the other end of the sleeve 611. A spring 613 is between the inner rod 612 and the sleeve 611. The inner rod 612 and the pressure sensor 620 are in active contact.

[0055] Further details need to be provided: Through the above structural design, the spring 613 can reset the inner rod 612. In actual use, the inner rod 612 transmits force to the pressure sensor 620, and the pressure sensor 620 also transmits force back to the inner rod 612. After being subjected to force, the inner rod 612 transmits force to the spring 613, which compresses. As the inner rod 612 gradually separates from the pressure sensor 620, the spring 613 can reset the inner rod 612. In addition, the end of the inner rod 612 near the pressure sensor 620 is round.

[0056] In actual use, when the inclined shaft transport vehicle 100 falls down the inclined shaft, the electric telescopic rod of the power component 330 is activated. The free end of the electric telescopic rod extends and pushes the protective frame 311 to rotate at a suitable angle. One end of the protective frame 311 moves out of the receiving groove 500. As the protective frame 311 rotates to a vertical state, the inner rod 612 of the elastic telescopic component 610 on the protective frame 311 continuously contacts the pressure sensor 620. The pressure sensor 620 receives the pressure and transmits the pressure signal to the drive component 420. When the pressure is greater than the set value, the free end of the electric telescopic rod of the drive component 420 pushes the baffle plate 410 to rotate. The baffle plate 410 and the side of the protective frame 311 come into contact.

[0057] When the inclined shaft transport vehicle 100 impacts the braking assembly 300, it will first contact and impact the primary wire rope 321, then impact the secondary wire rope 322 and the protective frame 311, providing tertiary braking protection. In addition, the protective clamp 312 can protect the inclined shaft transport vehicle 100 when it impacts the outer sides of the inclined shaft track 200, reducing the risk of the inclined shaft transport vehicle 100 slipping off the surface of the protective wire rope assembly 320 after impacting the protective wire rope assembly 320 and continuing to impact the outer sides of the inclined shaft track 200, thus achieving a further protective braking effect.

[0058] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. For those skilled in the art, various modifications and variations are possible with this utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
