The upper end of the sling chair is fixed with a rope holder, the steel wire rope is arranged on the top of the tunnel through a fixed pulley, and the driving wheel provides power for the circulation of the steel wire rope. When the mine cableway passenger device is in operation, the in-mine staff sits on the sling chair, the steel wire rope is driven by the driving wheel to drive the sling chair to go up or down (since the air intake inclined shaft has a significant slope, and the passenger device runs along the slope, the steel wire rope generally runs downward in the downhill direction, and upward in the uphill direction), and the rope holder passes above the fixed pulley without colliding with the fixed pulley. However, in the case of reverse rotation or rope breakage of the mine cableway passenger device, the steel wire rope and the sling chair rapidly slide down the in-mine inclined shaft under the action of the fixed pulley and gravity, resulting in a safety accident and a great safety hazard.

[0024] The technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only some embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0025] As shown in Figs. 1-3 The utility model discloses an air intake inclined shaft anti-sliding transportation system of overhead passenger conveying device, including: the steel wire rope 10 of setting along the air intake inclined shaft trend, the chair of being fixed on the steel wire rope 10 through the cable gripper, a plurality of anti-skid unit of being evenly spaced and being set along the air intake inclined shaft, wherein:

[0026] The steel wire rope 10 is wound on a driving wheel and a tail wheel, the driving wheel is installed at the entrance of the air intake inclined shaft, and the tail wheel is located at the bottom of the air intake inclined shaft; the driving wheel is used to make the steel wire rope 10 circulate by friction with the steel wire rope 10.

[0027] Each of the anti-slip units comprises a bearing crossbeam 11, a bearing column 12, a fixed pulley 13, an anti-slip horizontal rod 14 and an anti-slip baffle 15, wherein the bearing crossbeam 11 is arranged close to the top of the air intake inclined shaft and perpendicular to the air intake inclined shaft, and the two ends of the bearing crossbeam 11 are fixed on the two sides of the air intake inclined shaft; the bearing column 12 is located below the bearing crossbeam 11, and the upper end of the bearing column 12 is fixedly connected with the bearing crossbeam 11; the fixed pulley 13 is rotatably connected with the lower end of the bearing column 12; and the fixed pulley 13 is used to bear the steel wire rope 10.

[0028] The anti-slip horizontal rod 14 is horizontally arranged between the bearing crossbeam 11 and the fixed pulley 13, and is fixedly connected with the bearing column 12; and one side of the anti-slip horizontal rod 14, on which the steel wire rope 10 goes up, is a cut-off surface.

[0029] The upper end of the anti-slip baffle 15 is hingedly connected with the cut-off surface of the anti-slip horizontal rod 14, and the lower end of the anti-slip baffle 15 is used to rotate the anti-slip baffle 15 at the hinged point when the gripper goes up along the steel wire rope 10, so as to ensure smooth going up of the gripper; and when the gripper goes up due to reverse rotation or rope breakage, the anti-slip baffle 15 blocks the gripper from going down under the drive of the steel wire rope 10, so as to avoid the chair and the gripper from going down due to gravity.

[0030] When the coal mine operation is performed, the steel wire rope 10 drives the chair to normally go up, the gripper pushes the anti-slip baffle 15 to rotate at the hinged point when passing above the fixed pulley 13, so as to smoothly pass above the fixed pulley 13, and the lower end of the anti-slip baffle 15 is rotated back to the initial position (generally vertically downward) under the action of gravity after the gripper passes; when the mine overhead passenger device fails and the steel wire rope 10 drives the chair to go down during the going up process, the anti-slip baffle 15 cannot reversely rotate due to the obstruction of the anti-slip horizontal rod 14, so that the gripper is prevented from continuously going down when passing above the fixed pulley 13, thereby playing a function of preventing the chair from flying.

[0031] In some examples, the distance between the lower end of the anti-slip baffle 15 and the upper edge of the fixed pulley 13 is less than the diameter of the gripper, so that the anti-slip baffle 15 can block the gripper, and the gripper is prevented from passing through the gap between the lower end of the anti-slip baffle 15 and the upper edge of the fixed pulley 13.

[0032] In some examples, the anti-slip baffle 15 is a plate-shaped structure. Figs. 1-3, the stop surface of the anti-sliding horizontal rod 14 is also hingedly connected with a protection plate 17, which is arranged side by side with the anti-sliding baffle 15 and close to the main body of the cable gripper. When the cable gripper goes up along the steel wire rope 10, the protection plate 17 rotates at its hinged point and ensures smooth going up of the cable gripper. When the cable gripper reverses or breaks due to a fault during the going up process, the main body of the cable gripper is stopped by the protection plate 17 when it goes down under the drive of the steel wire rope 10.

[0033] In some examples, when the impact force of the chairlift is too large, the lower part of the anti-sliding baffle 15 may be deformed and unable to block the cable gripper. Therefore, with reference to Fig. 2 and Fig. 3 , the lower end of the anti-sliding baffle 15 is extended downward until it is below the fixed pulley 13. In this case, the lower end of the anti-sliding baffle 15 may affect the normal movement of the steel wire rope 10, so a receiving groove 16 for the steel wire rope 10 to pass through is formed below the anti-sliding baffle 15 to avoid the influence of the anti-sliding baffle 15 on the steel wire rope 10.

[0034] When the anti-sliding baffle 15 is impacted by the cable gripper, the lower end of the anti-sliding baffle 15 contacts the fixed pulley 13, which supports the lower end of the anti-sliding baffle 15 and buffers the impact force of the anti-sliding baffle 15, thereby improving reliability.

[0035] In some examples, because the contact area between the lower end of the anti-sliding baffle 15 and the fixed pulley 13 is too small, and the upper end of the anti-sliding baffle 15 is only hingedly connected with the anti-sliding horizontal rod 14, the reliability may gradually decrease with long-term use. Therefore, in order to increase the reliability of the anti-sliding baffle 15, with reference to Fig. 1 and Fig. 3 , a stop block 18 is fixed below the anti-sliding horizontal rod 14 and closely arranged on the side of the anti-sliding baffle 15. When the anti-sliding baffle 15 is impacted by the chairlift, the stop block 18 can buffer part of the impact force of the anti-sliding baffle 15, reduce the load on the anti-sliding baffle 15, prevent deformation of the middle part of the anti-sliding baffle 15, and prolong the service life of the anti-sliding baffle 15. Similarly, when the width of the stop block 18 is greater than that of the anti-sliding baffle 15 (not shown in the figure), the stop block 18 can also block the protection plate 17.

[0036] In some examples, the anti-sliding horizontal rod 14 is prone to loosening and deformation during long-term use, so with reference to Figs. 1-2In order to enhance the stability of the anti-sliding horizontal rod 14, the oblique support rod 19 is arranged between the anti-sliding horizontal rod 14 and the bearing column 12, the upper end of the support rod 19 is fixedly connected with the bearing column 12, and the lower end of the support rod 19 is fixedly connected with the anti-sliding horizontal rod 14, that is, the support rod 19, the anti-sliding horizontal rod 14 and the bearing column 12 form a right triangle, and the stability of the triangle itself makes the connection between the anti-sliding horizontal rod 14 and the bearing column 12 more stable.

[0037] In some examples, due to the connection between the anti-sliding baffle 15 and the anti-sliding horizontal rod 14 through the hinge, in the long-term working process, under the influence of factors such as wear and tear, mine moisture environment and the like, the anti-sliding baffle 15 becomes not flexible, thereby affecting the reset of the anti-sliding baffle 15. Moreover, the self-gravity of the anti-sliding baffle 15 is small, and the anti-sliding baffle 15 may not reset completely or in time. In order to avoid the above situation, with reference to Figs. 1-3 A counterweight 20 is arranged on the side of the anti-sliding baffle 15 away from the stopper 18, so as to increase the self-gravity of the anti-sliding baffle 15 and strengthen the reset ability of the anti-sliding baffle 15.

Moreover, the self-gravity of the anti-sliding baffle 15 is small, and the anti-sliding baffle 15 may not reset completely or in time. In order to avoid the above situation, with reference to
