DETAILED DESCRIPTION
[0022] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.
[0023] In the present disclosure, unless otherwise specified, the directional words such as "up", "down", "left", "right", etc. used to indicate the direction or position relationship are only for the convenience of describing the present disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, and a specific directional structure and operation. Therefore, it cannot be understood as a limitation of the present disclosure. The terms "inside" and "outside" refer to the inside and outside of the corresponding structural contour.
[0024] In addition, "up and down direction" can be seen Figure 1 In the vertical direction shown. In addition, it should be noted that the terms used, such as "first" and "second", are used to distinguish one element from another and do not have order or importance. In addition, in the description with reference to the drawings, the same number in different drawings represents the same element.
[0025] It should also be noted that, in the description of this disclosure, unless otherwise expressly specified or limited, the terms "disposed," "connected," "connected," and "installed" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integral connections; and they may refer to direct connections or indirect connections via an intermediary. Those skilled in the art will understand the specific meanings of these terms in this disclosure based on specific circumstances.
[0026] refer to Figures 1 to 2 Direction, the first aspect of the present disclosure provides a heavy vehicle shunting machine reducer brake, including a brake body 10, a cover plate 20, a travel stop 30, a sleeve 40, a first sealing structure 50 and an induction switch 60. The cover plate 20 covers the upper end opening of the brake body 10, and a through hole 21 is formed on the cover plate 20 that penetrates along its own thickness direction. The travel stop 30 is connected to the brake body 10 and is inserted into the through hole 21. The sleeve 40 is detachably connected to the cover plate 20 and is sleeved on the outer periphery of the travel stop 30. The first sealing structure 50 is arranged between the inner wall of the sleeve 40 and the outer wall of the travel stop 30, and respectively abuts against the inner wall of the sleeve 40 and the outer wall of the travel stop 30; the induction switch 60 is arranged opposite to the travel stop 30, and the travel stop 30 can move in the up and down directions driven by the brake body 10 to approach or move away from the induction switch 60.
[0027] Through the above technical scheme, on the one hand, the first sealing structure 50 arranged between the outer wall of the travel stop iron 30 and the inner wall of the sleeve 40 can achieve a good sealing effect, thereby reducing or avoiding oil leakage from the gap between the travel stop iron 30 and the sleeve 40. Under the cooperation of the sleeve 40 and the travel stop iron 30, at the same time, the setting of the sleeve 40 can also limit the range of movement of the first sealing structure 50 in the sleeve 40, thereby reducing or avoiding the wear of the first sealing structure 50 during the up and down movement of the travel stop iron 30; on the other hand, since the connection between the first sealing structure 50 and the travel stop iron 30 is located inside the sleeve 40, the sleeve 40 can shield smoke and dust, thereby preventing smoke and dust from directly passing through the gap between the first sealing structure 50 and the travel stop iron 30 into the interior of the brake body 10, causing equipment failure, so as to reduce the failure rate of the heavy vehicle shunting machine reducer brake and improve the service life of the heavy vehicle shunting machine reducer brake.
[0028] In addition, when the travel stop 30 moves up and down with the brake body 10, the distance between the end of the travel stop 30 close to the induction switch 60 and the induction switch 60 can be changed, thereby realizing the confirmation of the switch state of the heavy vehicle shunting machine reducer brake.
[0029] In order to facilitate the connection between the cover plate 20 and the brake body 10, as shown in FIG. Figure 1 、 Figure 2 As shown, a mounting hole 22 may be formed on the cover plate 20 , and the mounting hole 22 may be matched with an assembly hole preset on the brake body 10 by a fastening screw, thereby achieving locking and fixing of the cover plate 20 .
[0030] The above-mentioned induction switch 60 can also be connected to the remote terminal signal by wired or wireless means. In this way, the induction switch 60 can transmit the switch status of the heavy vehicle shunting machine reducer brake to the operator to realize the implementation monitoring of the heavy vehicle shunting machine reducer brake status.
[0031] In order to further avoid the situation in which the first sealing structure 50 is synchronously moved and thus wear of the first sealing structure 50 is caused during the up and down movement of the travel stop iron 30, in an exemplary embodiment provided in the present disclosure, as Figure 1 As shown, a first sealing ring groove 43 circumferentially arranged on the inner wall of the sleeve 40 can be formed. The first sealing structure 50 includes a first sealing ring 51, which is embedded in the first sealing ring groove 43 and sleeved on the outer circumference of the travel stop 30. Thus, after the first sealing ring 51 is embedded in the first sealing ring groove 43, the first sealing ring groove 43 can position and limit the first sealing ring 51, so that during the upward and downward movement of the travel stop 30, the first sealing ring 51 and the sleeve 40 are always in a relatively fixed state, thereby improving the stability of the fit between the first sealing ring 51 and the inner wall of the sleeve 40.
[0032] Alternatively, in another exemplary embodiment provided in the present disclosure, the above-mentioned first sealing ring groove 43 can also be formed on the outer peripheral surface of the travel stop iron 30. In this way, after the first sealing ring 51 is embedded in the first sealing ring groove 43, the first sealing ring groove 43 can play a role in positioning and limiting the first sealing ring 51, so that when the travel stop iron 30 moves up and down, the first sealing ring 51 and the travel stop iron 30 are in a relatively fixed state, thereby improving the stability of the cooperation between the first sealing ring 51 and the travel stop iron 30.
[0033] In order to further improve the sealing effect of the brake, further, such as Figure 1As shown, the inner wall of the sleeve 40 may also be formed with a second sealing ring groove 44 arranged around its own circumference. The second sealing ring groove 44 and the first sealing ring groove 43 are spaced apart in the vertical direction. The first sealing structure 50 includes a second sealing ring 52, which is embedded in the second sealing ring groove 44 and sleeved on the outer circumference of the travel stop 30. In this way, the cooperation between the first sealing ring 51 and the first sealing ring groove 43, and the cooperation between the second sealing ring 52 and the second sealing ring groove 44, can form a double seal between the travel stop 30 and the sleeve 40, further reducing the possibility of oil leakage from the gap between the travel stop 30 and the sleeve 40.
[0034] In order to improve the sealing performance between the travel stop 30 and the cover plate 20, the heavy vehicle shunting machine reducer brake provided in the present invention can also include a third sealing ring. For the embodiment in which the sleeve 40 and the cover plate 20 are connected through the first external thread 41 and the first internal thread 210, the third sealing ring can be connected between the first external thread 41 and the first internal thread 210.
[0035] The first sealing ring 51 , the second sealing ring 52 and the third sealing ring may all be made of rubber. Rubber has good high temperature resistance and wear resistance and has a longer service life.
[0036] The present disclosure does not limit the specific connection method between the sleeve 40 and the cover plate 20. For example, in an exemplary embodiment provided in the present disclosure, Figure 1 、 Figure 2 As shown, a first external thread 41 is formed on the outer wall of the end of the sleeve 40 near the cover plate 20 and arranged around the sleeve 40's circumference. A first internal thread 210 is formed on the wall of the through hole 21. The sleeve 40 and the cover plate 20 are threadedly connected via the first external thread 41 and the first internal thread 210. In this way, a detachable connection between the sleeve 40 and the cover plate 20 can be achieved by twisting the sleeve 40 or the cover plate 20, facilitating assembly and disassembly operations by operators. Furthermore, the threaded connection between the first external thread 41 and the first internal thread 210 can further reduce the gap between the outer wall of the sleeve 40 and the through hole 21 of the cover plate 20, thereby reducing oil leakage through the gap.
[0037] Alternatively, in another exemplary embodiment provided by the present disclosure, the sleeve 40 may also be connected in the through hole 21 by snapping.
[0038] In the present disclosure, to facilitate the movement of the travel stop 30 within the sleeve 40, the distance between the outer wall of the travel stop 30 and the inner wall of the sleeve 40 is 0.05 mm to 0.1 mm. Thus, when the distance between the outer wall of the travel stop 30 and the inner wall of the sleeve 40 is 0.05 mm to 0.1 mm, friction or interference between the travel stop 30 and the inner wall of the sleeve 40 during its vertical movement is avoided, while the gap between the two is minimized, thereby reducing oil leakage through the gap and improving the sealing performance of the brake of the heavy vehicle shunting machine reducer.
[0039] In addition, the end of the travel stop 30 close to the brake body 10 can also be connected to the brake body 10 in a detachable manner. For example, optionally, the heavy vehicle shunting machine reducer brake further includes a fastener 70, such as Figure 1 、 Figure 2 As shown, the travel stop 30 includes a mounting plate 31 and a connecting post 32 that are interconnected. A first fastening hole 310 is formed in the mounting plate 31, and a second fastening hole is formed in the brake body 10. Fasteners 70 are sequentially inserted through and locked into the first and second fastening holes 310. Fasteners 70 secure the mounting plate 31 to the brake body 10, thereby securing the connecting post 32 to the brake body 10. If the travel stop 30 malfunctions or becomes damaged, the two can be separated by tightening the fasteners 70. Only the travel stop 30 needs to be replaced, thus reducing repair and maintenance costs.
[0040] In another exemplary embodiment provided in the present disclosure, the connection between the travel stop 30 and the brake body 10 can also be achieved by welding, so that the two have a higher connection strength, avoiding loosening between the travel stop 30 and the brake body 10 when the brake body 10 drives the travel stop 30 to move up and down.
[0041] Likewise, in order to facilitate inspection and maintenance of the inductive switch 60 , in the present disclosure, the inductive switch 60 is detachably connected to the sleeve 40 .
[0042] The present disclosure does not limit the specific detachable connection method between the induction switch 60 and the sleeve 40. Figure 1 、 Figure 2As shown, in an exemplary embodiment provided by the present disclosure, the sleeve 40 can be connected to the inductive switch 60 by means of a thread. Specifically, a second external thread 42 can be formed on the outer wall of the sleeve 40 at the end away from the cover plate 20. The inductive switch 60 includes an inductive body 61 and a protective cover 62 disposed around the outer periphery of the inductive body 61. The protective cover 62 has an opening facing the sleeve 40. A second internal thread 620 can be formed on the inner wall of the protective cover 62. The sleeve 40 and the protective cover 62 are threadedly connected by the second external thread 42 and the second internal thread 620. In this way, the sleeve 40 and the protective cover 62 can be connected and removed by screwing the sleeve 40 or the protective cover 62, with minimal modification to the overall structure of the sleeve 40.
[0043] Alternatively, the sleeve 40 and the inductive switch 60 may be connected by any other means such as snap connection, magnetic connection, etc., which will not be elaborated in this disclosure.
[0044] Optionally, the induction switch 60 is a proximity switch. When the proximity switch detects that the travel stop 30 is close to or away from a certain degree, the switch information of the brake of the heavy vehicle shunting machine reducer can be judged.
[0045] Alternatively, in other embodiments provided in the present disclosure, the above-mentioned induction switch 60 can also be a distance sensor. In this way, the distance sensor can determine the switch status information of the heavy vehicle shunting machine reducer brake by detecting the specific position to which the travel stop 30 rises or falls.
[0046] The second aspect of the present disclosure provides a heavy vehicle shunting machine, comprising a plurality of the above-mentioned heavy vehicle shunting machine reducer brakes. The above-mentioned heavy vehicle shunting machine has all the beneficial effects of the above-mentioned reducer brakes, which are not described in this disclosure.
[0047] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings. However, the present disclosure is not limited to the specific details of the above embodiments. Within the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the scope of protection of the present disclosure.
[0048] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any appropriate manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.
[0049] In addition, the various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
