[0002] Currently, when a mining vehicle is performing transportation operations, due to brake failure or the need to stop stably, tire chocks are required to brake the mining vehicle. Generally, the tire chocks are fixed to the frame of the mining vehicle through a chock mounting structure, and the tire chocks are removed when in use.

[0003] In the process of implementing the embodiments of the present disclosure, it is found that at least the following problems exist in the related art:

[0004] The traditional chock mounting structure includes a positioning base plate and a mounting rod parallel to the positioning base plate. The middle of the mounting rod is fixedly connected to the positioning base plate. During installation, the chock body needs to be sleeved on the mounting rod, and then a pin is inserted into the end of the mounting rod to limit the chock body to prevent the chock body from detaching from the mounting rod. The other end of the chock body is fixedly pressed on the positioning base plate through another pin, so as to stably fix the chock through two-point connection. However, the operation is complex during use. When installing and disassembling the tire chock, multiple pins need to be inserted and pulled out for installation or disassembly. The installation and disassembly steps are cumbersome, which is not convenient for the installation and disassembly of the tire chock.

[0029] It should be noted that, without conflict, the embodiments in the embodiments of the present disclosure and the features in the embodiments can be combined with each other.

[0030] Combined Figures 1-3 As shown, an installation structure of a mining vehicle tire block is provided in an embodiment of the present disclosure, including: a block installation base body 100, a first locking pin plate 300, a second locking pin plate 400, a pin rod 500, a limiting portion, and a block main body 600. The block installation base body 100 is used to be fixed on a vehicle body 200; the first locking pin plate 300 is vertically arranged on the block installation base body 100 and is provided with a first pin hole 301; the second locking pin plate 400 is vertically arranged on the block installation base body 100 and is provided with a second pin hole 401. The first locking pin plate 300 and the second locking pin plate 400 are arranged in parallel, and there is a fixed gap 101 between them; the pin rod 500 can be movably inserted into the first pin hole 301 and the second pin hole 401; the limiting portion is arranged on one side of the first locking pin plate 300 or the second locking pin plate 400 and is used to limit the pin rod 500.

[0031] The block main body 600 is provided with a fixing hole 601. The position of the fixing hole 601 can be set in the fixed gap 101 between the first locking pin plate 300 and the second locking pin plate 400, and the pin rod 500 can be inserted into the fixing hole 601 to fix the block main body 600.

[0032] Adopt the mine vehicle tire block installation structure provided by the embodiments of the present disclosure. The block installation base body 100 is fixedly installed on the vehicle body 200, so that the block main body 600 can be installed on the vehicle body 200 through the block installation base body 100. A first locking pin plate 300 and a second locking pin plate 400 are respectively vertically provided on the block installation base body 100, and the first locking pin plate 300 and the second locking pin plate 400 are arranged in parallel. There is a fixed gap 101 between the first locking pin plate 300 and the second locking pin plate 400, which can accommodate the position where the block main body 600 is provided with a fixing hole 601. When installing the block main body 600, the position where the block main body 600 is provided with the fixing hole 601 is placed between the fixed gaps 101. A first pin hole 301 is provided on the first locking pin plate 300, and a second pin hole 401 is provided on the second locking pin plate 400. The pin rod 500 can respectively penetrate and insert into the first pin hole 301 and the second pin hole 401, and the pin rod 500 completely penetrates the fixing hole 601 located in the fixed gap 101. By inserting the pin rod 500 into the fixing hole 601, the block main body 600 can be restricted and fixed, and the block main body 600 can be quickly connected and fixed to the block installation base body 100. When it is necessary to remove the block main body 600, the pin rod 500 is pulled out from the first locking pin plate 300, the second locking pin plate 400 and the fixing hole 601, and the block main body 600 can be completely removed. By inserting and pulling out a single pin rod 500, the installation and disassembly of the block main body 600 can be controlled, greatly reducing the installation steps of the block main body 600 and improving the convenience of use for users.

[0033] Optionally, the inner diameter of the fixing hole 601 is greater than or equal to twice the diameter of the pin rod 500. In this way, the pin rod 500 can be conveniently inserted quickly through the larger fixing hole 601, preventing the problem that it is inconvenient to insert the pin rod 500 into the fixing hole 601 due to the too small inner diameter of the fixing hole 601.

[0034] Such as Figure 3As shown, optionally, the limiting part includes: an anti-drop rod 501 and a limiting baffle 102. The anti-drop rod 501 is arranged at one end of the latch rod 500; the limiting baffle 102 is arranged on one side of the first lock plate 300 or the second lock plate 400, and the limiting baffle 102 is provided with a through slot 103 that can accommodate the anti-drop rod 501 and the latch rod 500 to pass through. In this way, the anti-dropout rod 501 is set at one end of the latch rod 500. When the latch rod 500 is inserted or pulled out on the first lock pin plate 300 and the second lock pin plate 400, the latch rod 500 and the anti-dropout rod 501 can pass through the through slot 103 on the limiting baffle 102. The anti-dropout rod 501 on the latch rod 500 can only pass through the through slot 103. The other positions of the limiting baffle 102 will limit the movement of the anti-dropout rod 501. The through slot 103 on the limiting baffle 102 allows the anti-dropout rod 501 to pass through only when it is rotated to the through slot 103, thereby limiting the anti-dropout rod 501 and the latch rod 500 from slipping out of the first lock pin plate 300 and the second lock pin plate 400.

[0035] Optionally, the anti-dropout rod 501 is arranged at one end of the latch rod 500 close to the limit baffle 102. In this way, the anti-dropout rod 501 can be positioned by the limit baffle 102 to prevent the anti-dropout rod 501 from being separated from the first lock plate 300 and the second lock plate 400. When the anti-dropout rod 501 needs to be pulled out, the anti-dropout rod 501 can be removed by aligning the anti-dropout rod 501 with the through slot 103 on the limit baffle 102.

[0036] Optionally, the first latch hole 301 and the second latch hole 401 are circular hole structures, and the latch rod 500 is a circular rod structure. In this way, the circular latch rod 500 can be more flexible to rotate after being inserted into the first latch hole 301 and the second latch hole 401, and the anti-drop rod 501 can better drive the latch rod 500 to rotate, so that the anti-drop rod 501 is adjusted to align with the through slot 103, and the insertion and removal of the latch rod 500 are convenient.

[0037] Optionally, the anti-dropout rod 501 is a rod-shaped structure, which is vertically arranged between the latch rod 500. In this way, the anti-dropout rod 501 is a rod-shaped structure, which is convenient for swinging the anti-dropout rod 501, aligning the anti-dropout rod 501 with the through slot 103, and the anti-dropout rod 501 passes through the through slot 103 on the limit baffle 102, making it easier to pull out and insert the latch rod 500.

[0038] Optionally, the diameter of the anti-dropout rod 501 is smaller than or equal to the diameter of the latch rod 500. In this way, the diameter of the anti-dropout rod 501 is smaller than or equal to the diameter of the latch rod 500, so that the anti-dropout rod 501 can pass through the through slot 103 more easily, and the latch rod 500 can be used to lock or unlock the mask block body 600 more quickly.

[0039] like Figures 2-3As shown, optionally, the through slot 103 is a strip-shaped structure with an opening on one side of the limit baffle 102. When the anti-disengagement rod 501 rotates to be parallel to the through slot 103 of the strip-shaped structure, the anti-disengagement rod 501 can pass through the through slot 103. In this way, the through slot 103 is a strip-shaped structure with an opening on one side, and the anti-disengagement rod 501 is arranged at the end of the bolt rod 500. The through slot 103 can accommodate the bolt rod 500 to pass through. The anti-disengagement rod 501 can only pass through the through slot 103 of the strip-shaped structure. Adjust the anti-disengagement rod 501 to rotate around the bolt rod 500 so that the anti-disengagement rod 501 and the through slot 103 of the strip-shaped structure are in a parallel state, and the anti-disengagement rod 501 coincides with the through slot 103 of the strip-shaped structure. The anti-disengagement rod 501 can pass through the limit baffle 102 through the through slot 103. Only when the anti-disengagement rod 501 is rotated to a proper position can the bolt rod 500 be inserted or withdrawn, thereby preventing the bolt rod 500 from disengaging from the first locking plate 300 and the second locking plate 400 during vehicle operation and better maintaining the locking state of the mask body 600.

[0040] Optionally, the through slot 103, the first pin hole 301, and the second pin hole 401 are located on the same straight line, and the opening of the through slot 103 is located on the side edge of the limit baffle 102. In this way, when the first pin hole 301 and the second pin hole 401 are on the same straight line as the through slot 103, the bolt rod 500 can be inserted and withdrawn without obstruction. The opening of the through slot 103 penetrates the limit baffle 102 and can completely accommodate the anti-disengagement rod 501 to pass through the through slot 103, so that the length of the anti-disengagement rod 501 will not be limited by the length of the through slot 103, and the longer anti-disengagement rod 501 is convenient for grasping during operation.

[0041] Optionally, the mask mounting base 100 is vertically fixed to the side of the vehicle body 200, and the through slot 103 of the strip-shaped structure is horizontally arranged. In this way, the mask mounting base 100 is vertically fixedly connected to the vehicle body 200, which is convenient for installing the mask body 600 on the vehicle body 200. The through slot 103 of the strip-shaped structure is horizontally arranged, and the installation direction of the mask mounting base 100 and the through slot 103 of the strip-shaped structure are perpendicular. Under the action of gravity, the anti-disengagement rod 501 will always be in a vertically downward state, and the position between the anti-disengagement rod 501 and the through slot 103 can be kept staggered without force. The limit baffle 102 can be used to block the displacement of the anti-disengagement rod 501, and the bolt rod 500 can be better locked by limiting the anti-disengagement rod 501.

[0042] Optionally, an elastic reset structure can also be provided on the anti-detachment rod 501 so that its extending direction can be offset from the direction of the through groove 103 of the strip structure when no external force is applied. In this way, when an external force is applied to the anti-detachment rod 501 to align the anti-detachment rod 501 with the opening of the through groove 103, the anti-detachment rod 501 can pass through the through groove 103. Among them, the elastic reset structure can be a torsion spring or other structures. The specific setting method and structure are well-known technologies to those skilled in the art and will not be elaborated here.

[0043] As Figure 3 shown, optionally, the anti-detachment rod 501 is formed by extending and bending one end of the plug pin rod 500, and the anti-detachment rod 501 is perpendicular to the plug pin rod 500. In this way, the anti-detachment rod 501 and the plug pin rod 500 are integrally formed, and the anti-detachment rod 501 is formed by extending and bending one end of the plug pin rod 500, which facilitates the production of the plug pin rod 500 and the anti-detachment rod 501, and the overall strength is higher. The diameters of the anti-detachment rod 501 and the plug pin rod 500 can be the same, which is convenient for the anti-detachment rod 501 to pass through the through groove 103. The anti-detachment rod 501 and the plug pin rod 500 are in a vertical rod-shaped structure, so that the anti-detachment rod 501 can always be vertically downward under the action of gravity. By setting the direction of the through groove 103 to the horizontal direction, the opening direction of the through groove 103 will be offset from the pointing direction of the anti-detachment rod 501. Using the blocking of the anti-detachment rod 501 by the limit baffle 102 can prevent the plug pin rod 500 from being pulled out. When the plug pin rod 500 needs to be pulled out, swing the anti-detachment rod 501 to align with the opening of the through groove 103, and the anti-detachment rod 501 can pass through the through groove 103, so that the plug pin rod 500 can be pulled out.

[0044] As Figure 2 shown, optionally, the first lock pin plate 300 and the second lock pin plate 400 are arranged at a position near the upper part of the side surface of the mask mounting base 100, and a bending portion 700 for clamping the mask body 600 is provided at the position of the lower side edge of this side surface. In this way, by providing the bending portion 700 on one side of the mask mounting base 100, the bending portion 700 can fix the mask body 600. The bending portion 700 is arranged at the lower part of the mask mounting base 100 away from the first lock pin plate 300 and the second lock pin plate 400. One end of the mask body 600 can be first clamped on the bending portion 700, and the other end is then fixed by inserting the plug pin rod 500 on the first lock pin plate 300 and the second lock pin plate 400. By fixing both ends of the mask body 600 respectively, the mask body 600 is firmly connected to the mask mounting base 100, preventing the mask body 600 from swinging too much on the mask mounting base 100 and causing damage or abnormal noise. And the mask body 600 is inserted into the bending portion 700, and the connection between the mask body 600 and the bending portion 700 is simple, which is convenient for installation and disassembly.

[0045] Optionally, the block body 600 includes: a triangular frame and connecting crossbars. There are three triangular frames, and the three triangular frames are equally spaced and parallelly distributed on the same straight line, and the fixing holes 601 are provided on the triangular frames; there are also three connecting crossbars, and each connecting crossbar connects a corresponding vertex angle of the three triangular frames at the same time. In this way, the three triangular frames form a triangular prism structure through the connecting crossbars. The block body 600 in the shape of a triangular prism can be placed between the angle formed by the wheel and the bottom surface, increasing the contact area between the block body 600 and the tire, enhancing the stability of the block body 600 during use. The block body 600 being in the shape of a triangular prism can increase the load-bearing capacity of the block body 600 itself. The three triangular frames are arranged at a fixed distance and parallelly, and the three triangular frames can provide a stable supporting force for the block body 600, enabling the block body 600 to achieve a more stable supporting effect. The fixing holes 601 are provided on the triangular frames. After placing the triangular frames with the fixing holes 601 in the fixing gap 101, the pin rod is inserted into the fixing holes 601 to fixedly install the block body 600. The three connecting crossbars can stably connect the three triangular frames to form a stable whole.

[0046] Optionally, the width of the fixing gap 101 between the first locking plate 300 and the second locking plate 400 is greater than twice the width of the triangular frame. In this way, in the case of placing a single block body 600, the middle triangular frame on the single block body 600 can be snapped into the fixing gap 101. When two block bodies 600 need to be placed, the two block bodies 600 can be arranged side by side, and two adjacent triangular frames on the two block bodies 600 can be simultaneously snapped into the fixing gap 101, realizing the simultaneous fixation of the two block bodies 600 on the block mounting base 100. Through different placement methods, the installation of one block body 600 or the installation of two block bodies 600 can be achieved.

[0047] Optionally, the block body 600 further includes: a cover plate. The cover plate covers the outside of the three connecting crossbars. In this way, covering the outside of the three connecting crossbars with the cover plate can increase the contact surface of the block body 600, increase the contact area between the tire and the block body 600, and make the contact between the block body 600 and the tire closer. Covering the three connecting crossbars with the cover plate can also increase the stability between the three connecting crossbars, making the block body 600 more firm and stable.

[0048] Optionally, the cover plate is provided with anti-slip patterns. In this way, during use, the anti-slip patterns on the cover plate can increase the friction between the cover plate and the tire, enabling the block body 600 to more stably support the tire.

[0049] Optionally, the mask block mounting base 100 is of a rectangular structure. The first locking pin plate 300 and the second locking pin plate 400 are perpendicularly fixed to one side of the surface of the mask block mounting base 100. The bending portion 700 is formed by bending outward from the other side of the mask block mounting base 100. The bending direction of the bending portion 700 faces the side where the first locking pin plate 300 and the second locking pin plate 400 are provided. In this way, the bending portion 700 is integrally bent and formed with the mask block mounting base 100, which can increase the firmness between the bending portion 700 and the mask block mounting base 100 and can reduce the subsequent processing of the bending portion 700. The first locking pin plate 300 and the second locking pin plate 400 are welded and fixed to the mask block mounting base 100 and are arranged opposite to the bending portion 700, so as to respectively fix both ends of the mask block main body 600, thereby increasing the stability of the installation and connection of the mask block main body 600.

[0050] Optionally, there are vacancies on the covering plate to expose part of the connecting cross bar. In this way, one end of the bending portion 700 can extend into the vacancy on the covering plate, which is convenient for partially clamping the connecting cross bar into the bending portion 700, so that the bending portion 700 stably clamps the connecting cross bar.

[0051] As Figure 2 shown, optionally, there are two bending portions 700. In this way, both sides of one end of the mask block main body 600 can be fixed by the two bending portions 700. There is a fixed gap 101 in the middle of the upper first locking pin plate 300 and the second locking pin plate 400. The two bending portions 700 and the fixed gap 101 form a triangular distribution state on the mask block mounting base 100. Through the fixation between the two bending portions 700 and the fixed gap 101, the mask block main body 600 can be stably fixed on the mask block mounting base 100.

[0052] As Figure 2 shown, optionally, the bending portion 700 is a structure with an opening facing the direction of the insertion pin 500. In this way, through the opening of the bending portion 700, the mask block main body 600 can be conveniently inserted quickly. After insertion, the mask block main body 600 can be directly swung to the fixed gap 101, and the insertion pin 500 fixes the mask block main body 600 on the mask block mounting base 100, which is convenient for the installation and disassembly of the mask block main body 600 while ensuring the connection stability.

[0053] Optionally, the bending of the bending portion 700 is an arc structure, and the connecting cross bar is a cylindrical structure. In this way, when the mask block body 600 needs to be installed, the connecting cross bar on the mask block body 600 is inserted into the bending portion 700, and the mask block body 600 can be swung with the bending portion 700 as the center through the connecting cross bar, and the other end of the mask block body 600 is swung to a position where it is inserted into the first locking plate 300 and the second locking plate 400 to fix the mask block body 600. When the mask block body 600 needs to be removed, the mask block body 600 is swung with the bending portion 700 as the center through the connecting cross bar. Swing, the mask block body 600 gets rid of the first lock pin plate 300 and the second lock pin plate 400, and then the connecting cross bar is removed from the bending portion 700, and the mask block body 600 can be removed. The installation and disassembly of the mask block body 600 require the connecting cross bar to rotate in the bending portion 700. The inwardly bent portion of the bending portion 700 is set to an arc structure, and the connecting cross bar is set to a cylindrical shape, so that the connecting cross bar can rotate smoothly in the bending portion 700, reducing the interference of the bending portion 700 on the swing of the connecting cross bar.

[0054] Optionally, the length of the bending portion 700 is less than the distance between two adjacent triangular frames. In this way, the bending portion 700 can be arranged between two adjacent triangular frames, so as to facilitate the connecting crossbar to be completely immersed in the bending portion 700, and prevent the triangular frames from hindering the connecting crossbar from being completely extended into the bending portion 700, thereby increasing the stability of the connection between the bending portion 700 and the connecting crossbar.

[0055] When a cover plate is provided, the length of the bent portion 700 is smaller than the width of the gap on the cover plate. In this way, the bent portion 700 can be completely inserted into the gap on the cover plate, and the connecting cross bar on the cover plate is clamped on the bent portion 700, so that the mask block body 600 and the bent portion 700 are tightly clamped.

[0056] like Figures 1-2 As shown, optionally, an anti-lost chain 502 is connected between the mask block mounting base 100 and the latch rod 500. In this way, by connecting the anti-lost chain 502 between the mask block mounting base 100 and the latch rod 500, the latch rod 500 can be connected to the mask block mounting base 100 to prevent the latch rod 500 from being lost after being pulled out.

[0057] like Figures 1-2 As shown, optionally, a plurality of through holes 800 are provided on the mask block mounting base 100, and the plurality of through holes 800 are located on the same straight line. In this way, by providing a row of parallel through holes 800 on the mask block mounting base 100, the mask block mounting base 100 can be selectively connected to the vehicle body 200 through a plurality of through holes 800, and the position of the mask block mounting base 100 on the vehicle body 200 can be controlled, so that the mask block mounting base 100 can be conveniently installed on the vehicle body 200 without interfering with other components of the vehicle body 200.

[0058] Optionally, when the mask mounting base 100 is vertically mounted on the side of the vehicle body 200, the plurality of through holes 800 are located on the same vertical line. In this way, the vehicle body 200 can be selectively connected to the through holes 800 on the mask mounting base 100. The plurality of through holes 800 on the mask mounting base 100 are vertically arranged, and the heights between the through holes 800 are different. By selecting through holes 800 with different heights to connect to the vehicle body 200, the height of the mask mounting base 100 mounted on the vehicle body can be controlled.
