[0002] The statements herein only provide the background art related to the present invention and do not necessarily constitute the prior art.

[0003] The rail-holding car arrester is a safety device used in the mine transportation system, and its purpose is to quickly stop the mine car in case of emergency and prevent the mine car from sliding out of control.

[0004] The current rail-holding car arrester usually consists of a pawl, a driving mechanism for controlling the opening and closing of the pawl, and a spring buffer mechanism for alleviating the impact when the pawl is impacted by the mine car. Due to the complex working environment in the mine tunnel, various sundries will fall. In order to prevent the sundries from falling into the rail-holding car arrester and affecting its normal operation, generally, the exposed part at the top of the rail-holding car arrester is covered with a steel plate. However, due to the movement requirement of the pawl, there is still an opening at the pawl, and there is still a situation where impurities enter the inside of the rail-holding car arrester. At the same time, since the lower part of the rail-holding car arrester is buried below the ground, it is difficult for maintenance personnel to clean and maintain the impurities that enter its interior. Content of the Utility Model

[0005] The purpose of the utility model is to provide a mine car blocking device aiming at the above deficiencies at present, so as to achieve the purpose of convenient cleaning and maintenance.

[0010] The limiting component is composed of two guiding plates, and the pushing plate is located between the two guiding plates.

[0011] Furthermore, the impurity collection mechanism includes an outer box. A lifting groove is provided at the top of the outer box. An inner box capable of moving up and down is movably arranged in the lifting groove of the outer box. A slag collection groove is provided at the top of the inner box. A feeding hole communicating with the slag collection groove is provided on one side of the inner box close to the impurity discharging mechanism. Through holes are provided on both the bottom box and the outer box. When the inner box moves to the lower limit position, the through hole communicates with the feeding hole.

[0012] The impurity collection mechanism further includes a box cover, and the box cover is detachably arranged on the top of the outer box.

[0013] Furthermore, a cover plate is rotatably arranged at the feeding hole of the inner box through a torsion spring. When the inner box moves to the lower limit position and the torsion spring is in a natural state, one side of the cover plate is located in the sunk groove of the bottom box.

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figures 1-7 , the present utility model discloses a mine car arrester device, including a rail-clamping car arrester 1. An impurity discharging mechanism 2 is arranged at the bottom of the rail-clamping car arrester 1, and impurity collecting mechanisms 3 are arranged on both sides in the length direction of the impurity discharging mechanism 2; the impurity discharging mechanism 2 includes a bottom box 21 arranged at the bottom of the rail-clamping car arrester 1. A sunken groove is opened at the top of the bottom box 21, and two pushing mechanisms 22 are symmetrically arranged in the sunken groove of the bottom box 21 for pushing the impurities in the sunken groove to one side of the two impurity collecting mechanisms 3 respectively.

[0028] In the present utility model, by arranging the impurity discharging mechanism 2 at the bottom of the rail-clamping car arrester 1, the impurities falling into it can be regularly pushed out, and collected by the impurity collecting mechanisms 3 arranged on both sides of the impurity discharging mechanism 2, so that the user only needs to regularly clean the impurities in the impurity collecting mechanisms 3, achieving the purpose of convenient cleaning and maintenance.

[0029] In one embodiment, the pushing mechanism 22 includes a telescopic component 221, and a pushing plate 222 driven by the telescopic component 221 to move towards and away from one side of the impurity collecting mechanism 3 is arranged on one side of the telescopic component 221 close to the adjacent impurity collecting mechanism 3;

[0030] The push plate 222 is composed of a vertical section driven by the telescopic component 221 and an inclined section arranged at the top of the vertical section. An inclined surface for guiding the impurities at the top to slide towards the impurity collection mechanism 3 is arranged on the inclined section.

[0031] With such a design, when the push plate 222 is pushed by the telescopic component 221, the impurities falling onto the push plate 222 can slide along the inclined surface into the pushing area of the push plate 222, ensuring that as many of the fallen impurities as possible can be pushed by the push plate 222.

[0032] In one embodiment, a limiting component 23 for guiding the movement of impurities during the impurity pushing process is further arranged in the sunken groove of the bottom box 21;

[0033] The limiting component 23 is composed of two guiding plates 231, and the push plate 222 is located between the two guiding plates 231.

[0034] With such a design, the area between the two guiding plates 231 and the push plate 222 is the impurity pushing area. During equipment installation, the impurity pushing area is set below the pawl of the rail-mounted car arrester 1, so that the impurities falling from this place can all be in the pushing area of the push plate 222, thereby further ensuring that all the fallen impurities are pushed into the impurity collection mechanism 3.

[0035] In specific implementation, the telescopic component 221 can be selected as a pneumatic telescopic push rod, and is pneumatically driven together with the rail-mounted car arrester 1.

[0036] In one embodiment, the impurity collection mechanism 3 includes an outer box 31. A lifting groove is opened at the top of the outer box 31. An inner box 32 capable of moving up and down is movably arranged in the lifting groove of the outer box 31. A slag collection groove is opened at the top of the inner box 32. A feeding hole communicating with the slag collection groove is opened on the side of the inner box 32 close to the impurity discharging mechanism 2. Through holes are opened on both the bottom box 21 and the outer box 31. When the inner box 32 moves to the lower limit position, the through holes are communicated with the feeding hole;

[0037] The impurity collection mechanism 3 further includes a box cover 33, and the box cover 33 is detachably arranged on the top of the outer box 31.

[0038] With such a design, the impurities pushed out by the push plate 222 sequentially pass through the through holes and the feeding hole and enter the slag collection groove of the inner box 32 for collection. Maintenance personnel only need to regularly open the box cover 33, pull out the inner box 32 from the outer box 31, and clean the internal impurities.

[0039] In specific implementation, in order to facilitate the extraction of the inner box 32, a handle is arranged on the inner box 32.

[0040] In one embodiment, a cover plate 34 is rotatably arranged at the feeding hole of the inner box 32 through a torsion spring. When the inner box 32 moves to the lower limit position and the torsion spring is in a natural state, one side of the cover plate 34 is located in the sunken groove of the bottom box 21;

[0041] A spring bolt 35 is provided on the side of the cover plate 34 away from the rotating shaft. A slot for the spring bolt 35 to insert is formed on the inner box 32. When the cover plate 34 is completely located in the feeding hole, one end of the spring bolt 35 is inserted into the slot. An L-shaped top block 36 for ejecting the spring bolt 35 out of the slot when the inner box 32 moves to the lower limit position is provided on the outer box 31. A guide groove for the L-shaped top block 36 to move into is formed on the inner box 32.

[0042] With such a design, when the cover plate 34 rotates completely into the feeding hole, one end of the spring bolt 35 is inserted into the slot, restricting the cover plate 34 from resetting under the action of the torsion spring, which is convenient for maintenance personnel to place the inner box 32 into the outer box 31. During the placement process, the position of the guide groove is aligned with the L-shaped top block 36, so that after the inner box 32 moves to the lower limit position, the L-shaped top block 36 is inserted into the slot, ejecting the spring bolt 35 out of the slot. At this time, the cover plate 34 rotates into the sinking groove of the bottom box 21 under the action of the torsion spring, no longer blocking the feeding hole, enabling impurities to enter the inner box 32 for collection normally. When the inner box 32 is taken out, the cover plate 34 flips towards the feeding hole under the abutting action of the outer box 31 until the spring bolt 35 is inserted into the slot again, thereby avoiding the impurities collected inside from falling out during the process of taking out the inner box 32.

[0043] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present invention, the directional indications are only used to explain the relative positional relationship and movement conditions between components in a certain specific posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly.

[0044] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.

[0045] In addition, "a plurality" means more than two.

[0046] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
