Description
Technical Field
[0001] The utility model relates to the technical field of coal mining equipment, in particular to an anti-slip device for a walking trolley of a self-shifting machine tail. Background Art
[0002] During the coal mining process, it is necessary to use a self-shifting machine tail to dock with a conveyor, and transport coal blocks outward. The self-shifting machine tail includes a machine tail support and a walking trolley. The walking trolley includes a wheel frame, and the wheel frame is movably arranged on the machine tail support through small wheels. The walking trolley is docked with the head of the conveyor. During the coal mining process, within a certain moving stroke, the walking trolley moves on the machine tail support following the head of the loader, and the machine tail support does not move. When the conveyor moves beyond a certain stroke, the moving range of the walking trolley on the machine tail support has reached the end. At this time, the self-shifting machine tail starts to move relative to the conveyor, and the walking trolley moves relative to the machine tail support and resets to the head of the moving range on the machine tail support, so as to follow the conveyor to slide to the end of the moving range again. When the walking trolley moves on the machine tail support, the movement following the head of the conveyor is unidirectional. If the walking trolley has a long-distance backward movement, and the backward movement direction is opposite to the movement direction of the head of the conveyor, it is easy to cause unstable equipment connection and even damage the equipment. Summary of the Utility Model
[0003] The technical problem to be solved by the utility model is, aiming at the above-mentioned existing technical deficiencies, to provide an anti-slip device for a walking trolley of a self-shifting machine tail, which is beneficial to maintaining the unidirectional movement of the walking trolley following the conveyor and improving the equipment stability.
[0004] The technical solution adopted by the utility model is: to provide an anti-slip device for a walking trolley of a self-shifting machine tail, which is used to be arranged on the machine tail support and the wheel frame; and includes:
[0005] An anti-slip rack, which is used to be arranged on the machine tail support. The anti-slip rack has a plurality of protruding parts arranged at intervals in an array. The protruding part has a guiding surface and a stop surface, and the guiding surface is inclined relative to the stop surface;
[0006] A mounting seat, which has a limiting hole and is used to be arranged on the wheel frame and slide on the machine tail support following the wheel frame;
[0007] A pin shaft, which is inserted and arranged on the mounting seat;
[0008] The anti-rolling member is rotatably arranged relative to the mounting seat. The anti-rolling member successively has an anti-rolling part, a clamping part and a connecting part along the sliding direction of the mounting seat. The upper part of the anti-rolling part has a sleeving hole which is rotatably sleeved on the pin shaft. The lower part of the anti-rolling part has a locking surface and a lifting surface. The locking surface is used for abutting against the anti-reverse surface. After the locking surface abuts against the anti-reverse surface, one side of the anti-rolling part abuts against the mounting seat. The lifting surface is used for slidingly abutting against the guiding surface. After the lifting surface slidingly abuts against the guiding surface, the anti-rolling member rotates and the anti-rolling part rotates to the upper side of the anti-rolling rack. The clamping part is located on one side of the anti-rolling part. The clamping part has a first positioning hole and a second positioning hole. After the locking surface abuts against the anti-reverse surface, the first positioning hole is opposite to the limiting hole in position. After the anti-rolling part rotates to the upper side of the anti-rolling rack, the second positioning hole is opposite to the limiting hole in position. The upper side of the connecting part has a connecting hole.
[0009] To further optimize this technical solution, the lifting surface is inclined relative to the locking surface.
[0010] To further optimize this technical solution, the mounting seat includes:
[0011] A mounting plate for being arranged on the wheel carrier;
[0012] Side plates, there are two side plates. The two side plates are arranged in parallel on one side of the mounting plate. The anti-rolling member is located between the two side plates. The pin shaft penetrates through the two side plates. The limiting hole is located on the side plate.
[0013] To further optimize this technical solution, it further includes:
[0014] A tension spring, which is frustum-shaped. The end with a larger diameter is arranged on one side of the side plate. The tension spring is located beside the limiting hole;
[0015] A tension plate arranged at the end with a smaller diameter of the tension spring;
[0016] A plug pin located inside the tension spring. One end of the plug pin is arranged on the tension plate, and the other end is used for penetrating through the limiting hole and then being inserted into the first positioning hole or the second positioning hole.
[0017] To further optimize this technical solution, the end with a larger diameter of the tension spring is located outside the limiting hole.
[0018] To further optimize this technical solution, it further includes:
[0019] A positioning seat arranged at the upper end of the mounting seat;
[0020] The spring plate has one end disposed on the positioning seat and the other end acting on the upper end of the clamping portion. After the clamping portion rotates to the upper side of the anti-slip rack, the other end of the spring plate abuts against the upper end of the clamping portion.
[0021] The beneficial effects of the present utility model are as follows:
[0022] 1. The anti-slip rack is fixedly disposed on the tailstock support, and the anti-slip member is disposed on the wheel support. The anti-slip member is in one-way sliding fit with the anti-slip rack, which can prevent the wheel support (i.e., the walking trolley) from retreating. When the wheel support slides unidirectionally along with the transfer machine, the lifting surface of the anti-slip portion is in sliding abutment with the guiding surface of the anti-slip rack, and the anti-slip portion is lifted over the protruding portion of the anti-slip rack; when the wheel support makes a retreating movement, the locking surface of the anti-slip portion abuts against the anti-retreat surface of the anti-slip rack and cannot continue to retreat, effectively preventing the wheel support from making a long-distance retreat and realizing unidirectional sliding along with the transfer machine.
[0023] 2. The first positioning hole and the second positioning hole are both opposite to the position of the limiting hole. After the first positioning hole and the limiting hole are opposite, they can be locked by inserting a pin to keep the anti-slip portion in a vertical state, with the locking surface and the anti-retreat surface opposite and in abutment; after the anti-slip member rotates, the anti-slip portion rotates to the upper side of the anti-slip rack. At this time, the wheel support can slide freely back and forth. At the same time, the second positioning hole is opposite to the limiting hole, and a pin can be inserted for locking to keep the anti-slip portion in a state of being separated from the anti-slip rack, facilitating the movement and reset of the wheel support.
[0024] 3. The connection hole on the connecting portion can be used to connect with a rope. The rope can extend to the hands of the operator, facilitating the rotation of the anti-slip member by pulling the rope, enabling the anti-slip portion to rotate to the upper side of the anti-slip rack, making the application of force more convenient, and the rope can extend far away.

[0034] The present utility model will be further described in detail below with reference to the accompanying drawings and specific implementation manners
[0035] For the sake of simplicity of the drawings, only the parts related to the utility model are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, for the sake of simplicity and easy understanding of the drawings, in some figures, parts with the same structure or function are only schematically shown for one of them, or only one of them is marked. In this article, "one" not only means "only this one", but also can mean "more than one" situation, and "several" includes "two" and "more than two"
[0036] In this article, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations
[0037] In addition, in the description of this application, the terms "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance. The description of the front and rear directions is only for example and for easy understanding, and does not have the meaning of defining the coal mining advancing direction
[0038] Such as Figures 1-8As shown in the figure, the anti-slip device for the traveling trolley of the self-propelled shearer tail includes: an anti-slip rack 3, which is used to be arranged on the shearer tail support 1. The anti-slip rack 3 has a number of protruding parts 301 arranged in an interval array. The protruding part 301 has a guiding surface 3011 and a anti-retreat surface 3012, and the guiding surface 3011 is inclined relative to the anti-retreat surface 3012; a mounting seat 4, which has a limiting hole 4021, and the mounting seat 4 is used to be arranged on the wheel frame 2 and slide on the shearer tail support 1 following the wheel frame 2; a pin shaft 5, which is inserted into the mounting seat 4; an anti-slip member 6, which is rotatably arranged relative to the mounting seat 4. The anti-slip member 6 successively has an anti-slip part 601, a clamping part 602 and a connecting part 603 along the sliding direction of the mounting seat 4; the upper part of the anti-slip part 601 has a sleeving hole 6011, and the sleeving hole 6011 is rotatably sleeved on the pin shaft 5. The lower part of the anti-slip part 601 has a locking surface 6012 and a lifting surface 6013. The locking surface 6012 is used to abut against the anti-retreat surface 3012. After the locking surface 6012 abuts against the anti-retreat surface 3012, one side of the anti-slip part 601 abuts against the mounting seat 4; the lifting surface 6013 is used to slidably abut against the guiding surface 3011. After the lifting surface 6013 slidably abuts against the guiding surface 3011, the anti-slip member 6 rotates, and the anti-slip part 601 rotates to the upper side of the anti-slip rack 3; the clamping part 602 is located on one side of the anti-slip part 601. The clamping part 602 has a first positioning hole 6021 and a second positioning hole 6022. After the locking surface 6012 abuts against the anti-retreat surface 3012, the first positioning hole 6021 is opposite to the limiting hole 4021 in position; after the anti-slip part 601 rotates to the upper side of the anti-slip rack 3, the second positioning hole 6022 is opposite to the limiting hole 4021 in position; the upper side of the connecting part 603 has a connecting hole 6031.
[0039] During use, the anti-slip rack 3 is fixedly arranged on the tail support 1, and the anti-slip member 6 is arranged on the wheel support 2. The anti-slip member 6 slides back and forth on the tail support 1 following the wheel support 2. Taking the walking trolley following the transfer machine and sliding backward unidirectionally as an example, in the anti-slip rack 3, the guiding surface 3011 is located on the front side of the anti-retreat surface 3012. The anti-retreat surface 3012 is perpendicular to the side wall of the tail support 1, and the guiding surface 3011 is inclined. In the anti-slip member 6, from front to back are the connecting portion 603, the clamping portion 602, and the anti-slip portion 601. One end face of the anti-slip portion 601 close to the mounting seat 4 is used to prevent the anti-slip member 6 from rotating clockwise. When the wheel support 2 gradually slides backward following the head of the transfer machine, the lifting surface 6013 of the anti-slip portion 601 abuts against the guiding surface 3011 of the anti-slip rack 3. The lifting surface 6013 is lifted by the guiding surface 3011, and the anti-slip portion 601 rotates to the upper side of the anti-slip rack 3, crosses a convex portion 301 from the upper side, and then the anti-slip portion 601 rotates clockwise and falls beside the convex portion 301, realizing gradual sliding backward. The anti-slip member 6 can rotate clockwise naturally by its own weight. The upper side of the rear anti-slip portion 601 is rotatably sleeved with the pin shaft 5. The clamping portion 602 and the connecting portion 603 are both located on the front side of the anti-slip portion 601. Under its own weight, the anti-slip member 6 can rotate clockwise and fall around the pin shaft 5. When the wheel support 2 moves backward (i.e., slides forward), the locking surface 6012 abuts against the anti-retreat surface 3012, and the rear side of the anti-slip portion 601 abuts against the mounting seat 4. The anti-slip member 6 cannot continue to rotate clockwise, and the locking surface 6012 and the anti-retreat surface 3012 remain in an abutting state, realizing anti-backward movement. When the wheel support 2 moves backward to the end of the movable range, the self-propelled tail of the shearer moves backward as a whole, the transfer machine does not move, and the wheel support 2 (i.e., the walking trolley) needs to move forward relative to the tail support 1. At this time, manually rotate the anti-slip member 6 counterclockwise, the anti-slip portion 601 rotates above the anti-slip rack 3, and the second positioning hole 6022 and the limiting hole 4021 are opposite. Fix the anti-slip member 6 by inserting a pin into the limiting hole 4021 and the second positioning hole 6022. At this time, the wheel support 2 can freely move backward (i.e., move forward). Finally, the self-propelled tail of the shearer completes the overall backward movement, and the wheel support 2 moves to the starting position of the movable range, and then can continue to slide backward following the transfer machine.
[0040] If it is necessary to lock the hanging state of the anti-slip member 6, the first positioning hole 6021 and the limiting hole 4021 are opposite, the locking surface 6012 and the anti-retreat surface 3012 are opposite and in abutting contact. At this time, insert a pin into the limiting hole 4021 and the first positioning hole 6021.
[0041] The anti-slip member 6 is generally in a horizontally placed "Z" shape. The upper part of the connecting portion 603 can be higher than the anti-slip portion 601 and the clamping portion 602. The connecting hole 6031 can be connected to a rope, which is convenient to pull the anti-slip member 6 to rotate counterclockwise through telescopic pulling, so that the anti-slip portion 601 rotates to the upper side of the anti-slip rack 3, facilitating the overall backward reset of the wheel support 2.
[0042] Further, the lifting surface 6013 is inclined relative to the locking surface 6012.
[0043] During use, the lifting surface 6013 is inclined relative to the locking surface 6012. When the anti-slip portion 601 is in the vertical state, the locking surface 6012 is vertical, the lifting surface 6013 is inclined relative to the vertical direction, the wheel carrier 2 moves backward, and the lifting surface 6013 slidably abuts against the guiding surface 3011, facilitating the lifting of the anti-slip portion 601 above the anti-slip rack 3.
[0044] Further, the mounting seat 4 includes: a mounting plate 401 for being arranged on the wheel carrier 2; two side plates 402 which are arranged in parallel on one side of the mounting plate 401. The anti-slip member 6 is located between the two side plates 402. The pin shaft 5 penetrates through the two side plates 402, and the limiting holes 4021 are located on the side plates 402.
[0045] During use, the anti-slip portion 601 approaches the mounting plate 401 of the mounting seat 4. When the locking surface 6012 abuts against the anti-retreat surface 3012, the rear side of the anti-slip portion 601 abuts against the front side surface of the mounting plate 401, restricting the clockwise rotation of the anti-slip member 6. Limiting holes 4021 can be provided on both of the two side plates 402, and the through setting is more convenient for the insertion connection of the pins.
[0046] Further, it further includes: a tension spring 7 which is frustum-shaped, and the larger-diameter end is arranged on one side of the side plate 402. The tension spring 7 is located beside the limiting hole 4021; a pull plate 8 arranged at the smaller-diameter end of the tension spring 7; a plug pin 9 located inside the tension spring 7. One end of the plug pin 9 is arranged on the pull plate 8, and the other end is used for inserting into the first positioning hole 6021 or the second positioning hole 6022 after penetrating through the limiting hole 4021.
[0047] The larger-diameter end of the tension spring 7 is located outside the limiting hole 4021.
[0048] During use, the tension spring 7 can position the plug pin 9 (i.e., the pin when the positioning hole and the limiting hole 4021 are inserted), prevent the loss of the plug pin 9, and can maintain the inserted state at the same time. The tension spring 7 is fixedly arranged on one side plate 402 and is opposite to the position of the limiting hole 4021. When it is necessary to use the plug pin 9 to insert and connect the side plate 402 and the clamping portion 602, the plug pin 9 is made to penetrate through the limiting hole 4021 and the first positioning hole 6021 or the second positioning hole 6022. At this time, the tension spring 7 applies a thrust to the plug pin 9 to maintain the inserted state of the plug pin 9 and prevent it from sliding out automatically.
[0049] When the bolt 9 does not need to be inserted into the limit hole 4021, pull the pull plate 8 outward. The tension spring 7 becomes longer. The end of the bolt 9 disengages from the limit hole 4021 and deviates in the axial direction of the limit hole 4021. The end of the bolt 9 abuts against the upper area of the side plate 402, and the tension spring 7 applies a force to make the bolt 9 abut against the side plate 402. The bolt 9 can abut against the limit plate between the larger diameter end of the tension spring 7 and the limit hole 4021. To more stably disengage from the limit hole 4021, after stretching the tension spring 7, the distance between the coils of the tension spring 7 becomes larger, so that the bolt 9 obliquely penetrates out of the tension spring 7 and abuts against the side surface of the side plate 402 outside the tension spring 7.
[0050] Further, it further includes: a positioning seat 10 provided at the upper end of the mounting seat 4; a spring piece 11, one end of which is provided on the positioning seat 10 and the other end acts on the upper end of the clamping portion 602. After the clamping portion 602 rotates to the upper side of the anti-slip rack 3, the other end of the spring piece 11 abuts against the upper end of the clamping portion 602.
[0051] During use, the positioning seat 10 can be inserted or welded to the upper end of the mounting seat 4. The spring piece 11 can be a "V" - shaped structure. One side is inserted and fixed on the positioning seat 10, and the other side is close to or abuts against the upper end of the anti - slip portion 601 and / or the clamping portion 602. When the wheel carrier 2 moves backward and the anti - slip member 6 is lifted by the guiding surface 3011, the upper end of the clamping portion 602 abuts against the spring piece 11 and compresses the spring piece 11 to store energy. When the anti - slip portion 601 naturally falls clockwise after passing over the convex portion 301, the spring piece 11 is released and actively pushes the anti - slip portion 601 to fall, increasing the probability of the anti - slip member 6 falling and reducing the problem that the anti - slip member 6 cannot quickly rotate and fall between the convex portions 301 due to frictional resistance and other reasons.
