Description

Technical Field

[0001] This invention relates to the field of mining machinery maintenance technology, and more specifically, to a fixing device for a mining car body. Background Technology

[0002] Heavy-duty mining cars have a strong load-bearing capacity and adaptability to various environments, making them an important transportation equipment for materials in open-pit mines. Over time, the repeated loading and unloading of minerals in heavy-duty mining cars causes significant wear and impact on the bottom of the buckets. This can lead to problems such as excessive wear, deformation, cracking, and damage, requiring regular welding repairs to ensure normal operation and extend the service life of the buckets.

[0003] Welding repairs of heavy-duty mining car boxes usually require the installation of supports to secure the boxes. However, due to the weight and size of heavy-duty mining car boxes, setting up supports is quite cumbersome. When fixing the heavy-duty mining car box to the supports, it is necessary to first place the heavy-duty mining car box on the supports and then fix it. This makes the installation and fixing of the heavy-duty mining car box quite complicated. At the same time, the heavy-duty mining car box may shift during the fixing process, affecting the fixation of the heavy-duty mining car box and delaying coal mining and transportation time. Summary of the Invention

[0004] The main objective of this invention is to provide a fixing device for a mine car body, so as to solve the problem of low efficiency in fixing the mine car body by operating external devices in related technologies.

[0005] To achieve the above objectives, the present invention provides a fixing device for a mine car body, characterized in that it comprises: a support assembly having a positioning groove, wherein a first reinforcing rib of the mine car body is located within the positioning groove; a first channel being disposed within the support assembly, with a first end extending to the groove wall of the positioning groove; a clamping assembly having a portion of its structure disposed within the first channel, and the remaining portion extending into the positioning groove, the clamping assembly being movably disposed and having a clamping position for clamping the first reinforcing rib and a disengaging position for releasing the first reinforcing rib; and a switching member being movably disposed within the positioning groove along the depth direction of the positioning groove, for cutting... The switching component has a second channel and a third channel, with the third channel located on the side of the second channel away from the positioning groove. The second or third channel is connected and cooperates with the first channel. A power source is also included, which is connected to the first channel through the second channel. When the first reinforcing rib presses against the switching component, the switching component moves to the position where the second channel connects to the first channel, and the power source drives the clamping assembly to move from the separation position to the clamping position through the first channel. When the first reinforcing rib leaves the positioning groove, the switching component moves to the position where the first channel connects to the third channel, and the first channel is connected to the outside of the fixing device of the mine car body through the third channel, so that the clamping assembly moves from the clamping position to the separation position.

[0006] Furthermore, the switching component includes a guide post, with both the second and third channels disposed on the guide post. The support assembly is provided with mounting holes, and the guide post is movably disposed within the mounting holes.

[0007] Furthermore, the fixing device for the mine car body also includes a first elastic element, which is disposed between the guide post and the bottom wall of the mounting hole. The first elastic element applies an elastic force toward the positioning groove to the guide post. And / or, the fixing device for the mine car body also includes a second elastic element, which is disposed between the side wall of the first channel near the positioning groove and the clamping assembly.

[0008] Furthermore, the support assembly is also provided with a fourth channel, which extends to the side wall of the support assembly. When the first reinforcing rib presses against the switching piece, the first channel connects with the fourth channel through the second channel.

[0009] Furthermore, the support component is provided with a fifth channel that is externally connected. The fifth channel and the fourth channel are spaced apart along the axis of the switching component. When the first reinforcing rib leaves the positioning groove, the first channel is connected to the fifth channel through the third channel.

[0010] Furthermore, the second channel is a first arc-shaped groove, and the third channel is a second arc-shaped groove. On the projection of the switching component along the axial direction, one end of the first arc-shaped groove and one end of the second arc-shaped groove coincide.

[0011] Furthermore, the fixing device of the mine car body also includes an anti-rotation structure, which is set between the guide post and the side wall of the mounting hole. The anti-rotation structure includes a limiting groove and a limiting block. The center line of the limiting groove is parallel to the axis of the guide post. The limiting block can move within the limiting groove. One of the limiting block and the limiting groove is set on the inner side wall of the mounting hole, and the other of the limiting block and the limiting groove is set on the outer side wall of the guide post.

[0012] Furthermore, the guide post includes a large-diameter post section and a small-diameter post section. The second channel and the third channel are both set on the small-diameter post section. The mounting hole includes a large-diameter hole section and a small-diameter hole section. The height of the large-diameter hole section is greater than the height of the large-diameter post section. The large-diameter post section is located inside the large-diameter hole section, and the small-diameter post section is located inside the small-diameter hole section. The small-diameter hole section is located between the large-diameter hole section and the positioning groove. A stepped surface is formed between the large-diameter hole section and the small-diameter hole section. The end of the large-diameter post section facing the small-diameter post section is limited and matched with the stepped surface.

[0013] Furthermore, the first reinforcing rib extends along the front-rear direction of the mine car body. The fixing device of the mine car body also includes a positioning member, which is set in a positioning groove. The positioning member is arranged opposite to the clamping assembly. When the clamping assembly is in the clamping position, the first reinforcing rib is clamped between the positioning member and the clamping assembly. The bottom of the mine car body is also provided with a second reinforcing rib connected to the first reinforcing rib. The second reinforcing rib extends along the left-right direction of the mine car body. There is an angle between the first reinforcing rib and the second reinforcing rib. The fixing device of the mine car body also includes an anti-detachment member, which extends along the front-rear direction of the mine car body. The anti-detachment member is hinged to the support assembly and hooked to the second reinforcing rib.

[0014] Furthermore, the fixing device of the mine car also includes a limiting member, which is spaced apart from the support component and located on the side of the support component, and the limiting member cooperates with the side wall of the mine car for limiting.

[0015] Furthermore, the fixing device for the mine car also includes a leveling component, which is spaced apart from the support component along the length of the mine car.

[0016] Furthermore, the fixing device of the mine car body also includes a base, on which a traveling mechanism is installed, and support components, limiting components and leveling components are all installed on the base.

[0017] According to the technical solution of this invention, the first reinforcing rib of the mine car body is located in a positioning groove, which is set on a support assembly. A first channel is provided within the support assembly, with its first end extending to the wall of the positioning groove. Part of the clamping assembly is located within the first channel, and another part is located within the positioning groove. The clamping assembly is movably configured; when in the clamping position, it clamps the first reinforcing rib; when in the disengaged position, it separates from the first reinforcing rib. A switching element is provided within the positioning groove, moving along the depth direction of the groove. The switching element has a second channel and a third channel, with the third channel located on the side of the second channel away from the positioning groove. The second or third channel communicates with and engages with the first channel. A power source communicates with the first channel through the second channel. When the first reinforcing rib presses against the switching element, the second channel communicates with the first channel, and the power source drives the clamping assembly from the disengaged position to the clamping position. When the first reinforcing rib leaves the positioning groove, the first channel moves to communicate with the third channel, which in turn communicates with the exterior of the mine car body's fixing device, and the clamping assembly moves from the clamping position to the disengaged position. With the above configuration, the mine car body is placed on the fixing device of the mine car body. The first reinforcing rib presses against the switching component, and the second channel of the switching component moves to connect with the first channel, allowing the power source to connect with the first channel. The power source then drives the clamping assembly from the separated position to the clamping position. That is, under the weight of the mine car body, the first reinforcing rib is clamped, fixing the mine car body to the fixing device. This avoids the need to operate external devices to fix the car body, making fixing the car body simpler and improving the efficiency of fixing the mine car body. When the mine car body separates from the fixing device, the first reinforcing rib separates from the clamping assembly. The clamping assembly moves along the depth direction of the positioning groove to the third channel, connecting with the first channel. The third channel connects to the outside of the fixing device, cutting off the connection between the power source and the clamping assembly. The power source no longer provides a driving function, and the clamping assembly can move to the separated position. Therefore, the technical solution of this application effectively solves the problem of low efficiency in fixing mine car bodies using external devices in related technologies.

[0034] like Figure 1 , Figures 3 to 5 as well as Figure 10As shown, in this embodiment, a fixing device for a mine car body includes: a support assembly 10, a first channel 20, a clamping assembly 30, a switching element 40, and a power source 50. The support assembly 10 is provided with a positioning groove 11, and the first reinforcing rib 2 of the mine car body 1 is located within the positioning groove 11. The first channel 20 is disposed within the support assembly 10, and its first end extends to the groove wall of the positioning groove 11. A portion of the clamping assembly 30 is disposed within the first channel 20, and the remaining portion extends into the positioning groove 11. The clamping assembly 30 is movably disposed and has a clamping position for clamping the first reinforcing rib 2 and a disengaging position for releasing the first reinforcing rib 2. The switching element 40 is movably disposed within the positioning groove 11 along its depth direction. The switching element 40 has a second channel 41 and a third channel 42, with the third channel 42 located on the side of the second channel 41 away from the positioning groove 11. The second channel 41 or the third channel 42 communicates and cooperates with the first channel 20. The power source 50 is connected to the first channel 20 via the second channel 41. When the first reinforcing rib 2 presses against the switching member 40, the switching member 40 moves to the position where the second channel 41 connects to the first channel 20, and the power source 50 drives the clamping assembly 30 from the separated position to the clamped position via the first channel 20. When the first reinforcing rib 2 leaves the positioning groove 11, the switching member 40 moves to the position where the first channel 20 connects to the third channel 42, and the first channel 20 connects to the outside of the fixing device of the mine car body via the third channel 42, so that the clamping assembly 30 moves from the clamped position to the separated position.

[0035] Applying the technical solution of this invention, the first reinforcing rib 2 of the mine car body 1 is located within the positioning groove 11, which is mounted on the support assembly 10. A first channel 20 is provided within the support assembly 10, with its first end extending to the wall of the positioning groove 11. A portion of the clamping assembly 30 is located within the first channel 20, and another portion is located within the positioning groove 11. The clamping assembly 30 is movably mounted; when in the clamping position, it clamps the first reinforcing rib 2; when in the disengaged position, it separates from the first reinforcing rib. A switching element 40 is provided within the positioning groove 11, moving along the depth direction of the positioning groove 11. The switching element 40 has a second channel 41 and a third channel 42, with the third channel 42 located on the side of the second channel 41 away from the positioning groove. The second channel 41 or the third channel 42 communicates and engages with the first channel 20. The power source communicates with the first channel 20 through the second channel 41. When the first reinforcing rib 2 presses against the switching piece 40, the second channel 41 connects with the first channel 20, and the power source 50 drives the clamping assembly 30 to move from the separated position to the clamping position. When the first reinforcing rib 2 leaves the positioning groove 11, the first channel 20 moves to connect with the third channel 42, and the first channel 20 connects with the outside of the fixing device of the mine car body, and the clamping assembly 30 moves from the clamping position to the separated position. With the above setup, the mine car 1 is placed on the fixing device of the mine car, the first reinforcing rib 2 presses against the switching piece 40, and the second channel 41 of the switching piece 40 moves to connect with the first channel 20, so that the power source 50 can connect with the first channel 20. Then the power source 50 can drive the clamping assembly 30 to move from the separated position to the clamping position, that is, the first reinforcing rib 2 is clamped under the action of the mine car's own weight. When fixing the mine car 1 to the fixing device of the mine car, it is avoided to operate the external device to fix the mine car 1, making the fixing of the mine car 1 simpler and improving the fixing efficiency of the mine car 1. When the mine car body 1 separates from the fixing device of the mine car body, the first reinforcing rib 2 separates from the clamping assembly 30. The clamping assembly 30 moves along the depth direction of the positioning groove 11 to the third channel 42, which connects with the first channel 20. The third channel 42 is connected to the outside of the fixing device of the mine car body, cutting off the connection between the power source 50 and the clamping assembly 30. The power source 50 no longer plays a driving role, and the clamping assembly 30 can move to the separation position. Therefore, the technical solution of this application effectively solves the problem of low efficiency in fixing the mine car body by operating the external device in the related technology.

[0036] It should be noted that the power source 50 is a hydraulic station, which outputs hydraulic oil. Of course, in other embodiments, the power source 50 can also be an air source, outputting compressed gas. The fourth channel 13 and the fifth channel 14 are both connected to the power source 50. The external connection of the third channel 42 to the fixing device of the mine car body means that the third channel 42 is connected to the power source, or it can be connected to the power source recovery device. A protective box for protecting the hydraulic station is welded onto the base. The protective box has a door; opening the door allows operation of the hydraulic station. The clamping assembly 30 having a separation position for releasing the first reinforcing rib 2 means that the clamping assembly is separated from the first reinforcing rib.

[0037] like Figures 3 to 5 As shown, in this embodiment, the switching component 40 includes a guide post 43. The second channel 41 and the third channel 42 are both disposed on the guide post 43. The support assembly 10 has a mounting hole 12, and the guide post 43 is movably disposed within the mounting hole 12. The guide post 43 can move within the mounting hole 12 along the depth direction of the positioning groove 11, thereby enabling the second channel 41 or the third channel 42 to connect with the first channel 20.

[0038] like Figures 3 to 5 As shown, in this embodiment, the fixing device for the mine car body further includes a first elastic element 60, which is disposed between the guide post 43 and the bottom wall of the mounting hole 12. The first elastic element 60 applies an elastic force toward the positioning groove 11 to the guide post 43. The fixing device for the mine car body also includes a second elastic element 70, which is disposed between the side wall of the first channel 20 near the positioning groove 11 and the clamping assembly 30. When the mine car body 1 is installed to the fixing device for the mine car body, the first reinforcing rib 2 compresses the guide post 43, and the guide post 43 compresses the first elastic element 60, thereby storing elastic potential energy inside the first elastic element 60. The clamping assembly 30 moves toward the center of the positioning groove 11, compressing the second elastic element 70, thereby storing elastic potential energy inside the second elastic element 70. When the mine car 1 is removed from the fixing device of the mine car, the first elastic member 60 can apply an elastic force to the guide post 43, causing the guide post 43 to move towards the top of the positioning groove 11, so that the third channel 42 can connect with the first channel 20, that is, the first channel 20 is connected to the outside of the fixing device of the mine car. The second elastic member 70 applies an elastic force away from the positioning groove 11 to the clamping assembly 30, and the clamping assembly 30 can move from the clamping position to the separation position.

[0039] Specifically, in this embodiment, the first elastic element 60 is a first spring, and the second elastic element 70 is a second spring; alternatively, the materials of the first elastic element 60 and the second elastic element 70 can be other elastic substances. The external connection between the first channel 20 and the fixing device of the mine car body means that the first channel 20 is connected to the power source through the fifth channel 14, or it can be connected to the power source recovery device.

[0040] like Figure 3 and Figure 5 As shown, in this embodiment, the support component 10 is further provided with a fourth channel 13, which extends to the side wall of the support component 10. When the first reinforcing rib 2 presses against the switching member 40, the first channel 20 communicates with the fourth channel 13 through the second channel 41. The fourth channel 13 enables the power source 50 to communicate with the clamping component 30 through the fourth channel 13, the second channel 41, and the first channel 20 when the mine car 1 is installed on the fixing device of the mine car 1, thereby driving the clamping component 30 to move from the separated position to the clamping position.

[0041] like Figure 5 As shown, in this embodiment, the support component 10 is provided with an externally connected fifth channel 14. The fifth channel 14 and the fourth channel 13 are spaced apart along the axial direction of the switching component 40. When the first reinforcing rib 2 leaves the positioning groove 11, the first channel 20 is connected to the fifth channel 14 through the third channel 42. When the mine car 1 is separated from the fixing device of the mine car 1, the guide post 43 moves towards the positioning groove 11 under the action of the first elastic member 60, so that the third channel 42 and the fifth channel 14 can be connected, and then the first channel 20 can be connected to the fifth channel 14. The power source no longer drives the clamping component 30, and the clamping component 30 can move from the clamping position to the separation position. The fifth channel 14 and the fourth channel 13 are spaced apart, which can prevent the power source 50 from being connected to the fourth channel 13 and the fifth channel 14 at the same time, thus affecting the normal operation of the fixing device of the mine car 1.

[0042] Preferably, in this embodiment, both the fourth channel 13 and the fifth channel 14 extend along the length of the mine car 1, and their axes are coaxial. This facilitates the connection of the first channel 20, the second channel 41, and the fourth channel 13, or the first channel 20, the third channel 42, and the fifth channel 14, when the guide post 43 moves. The first channel 20 includes a first pipe section extending along the width of the mine car 1, a second pipe section extending along the depth of the positioning groove 11, and a third pipe section extending along the width of the mine car 1. The second pipe section is disposed between the first and third pipe sections and communicates with them. The distance between the third pipe section and the opening of the positioning groove 11 is less than the distance between the first pipe section and the opening of the positioning groove 11. The second elastic member 70 is disposed between the limiting plate and the side wall of the third pipe section near the positioning groove 11.

[0043] like Figures 3 to 5As shown, in this embodiment, the second channel 41 is a first arc-shaped groove 411, and the third channel 42 is a second arc-shaped groove 421. On the projection along the axis of the switching member 40, one end of the first arc-shaped groove 411 and one end of the second arc-shaped groove 421 coincide. The first arc-shaped groove 411 allows the power source 50 to flow more smoothly within the second channel 41, and the second arc-shaped groove 421 allows the power source 50 to flow more smoothly within the third channel 42. The arrangement of the first arc-shaped groove 411 and the second arc-shaped groove 421 also makes the arrangement of the fourth channel 13 and the fifth channel 14 on the support assembly 10 more reasonable. On the projection of the switching component 40 along the axial direction, one end of the first arc groove 411 and one end of the second arc groove 421 coincide, so that when the guide post 43 moves along the depth direction of the positioning groove 11, the first arc groove 411 and the second arc groove 421 can be connected to the first channel 20 respectively, making the structure of the guide post 43 more reasonable and the overall structure of the fixing device of the mine car body simpler.

[0044] like Figures 3 to 5 As shown, in this embodiment, the fixing device of the mine car body further includes an anti-rotation structure 80. The anti-rotation structure 80 is disposed between the guide post 43 and the side wall of the mounting hole 12. The anti-rotation structure 80 includes a limiting groove 81 and a limiting block 82. The center line of the limiting groove 81 is parallel to the axis of the guide post 43. The limiting block 82 can move within the limiting groove 81. One of the limiting block 82 and the limiting groove 81 is disposed on the inner side wall of the mounting hole 12, and the other of the limiting block 82 and the limiting groove 81 is disposed on the outer side wall of the guide post 43. The limiting block 82 and the limiting groove 81 can prevent the guide post 43 from rotating during movement, thereby preventing the rotation of the guide post 43 from causing changes in the position of the first channel 20 and the second channel 41, affecting the connection between the first channel 20 and the second channel 41 or the connection between the first channel 20 and the third channel 42. The limiting block 82 can move within the limiting groove 81, that is, the limiting block 82 and the limiting groove 81 will not interfere with the movement of the guide post 43.

[0045] Specifically, in this embodiment, the limiting block 82 is disposed on the outer wall of the large-diameter column section 431, and the limiting groove 81 is disposed on the inner wall of the large-diameter hole section 121. In the projection along the axial direction of the switching member 40, one end of the first arc-shaped groove 411, one end of the second arc-shaped groove 421, and the limiting block 82 coincide. The projections of one end of the first arc-shaped groove 411, one end of the second arc-shaped groove 421, and the limiting block 82 onto a plane perpendicular to the axis of the switching member have overlapping portions.

[0046] like Figures 3 to 5As shown, in this embodiment, the guide post 43 includes a large-diameter post section 431 and a small-diameter post section 432. The second channel 41 and the third channel 42 are both disposed on the small-diameter post section 432. The mounting hole 12 includes a large-diameter hole section 121 and a small-diameter hole section 122. The height of the large-diameter hole section 121 is greater than the height of the large-diameter post section 431. The large-diameter post section 431 is located inside the large-diameter hole section 121, and the small-diameter post section 432 is located inside the small-diameter hole section 122. The small-diameter hole section 122 is located between the large-diameter hole section 121 and the positioning groove 11. A stepped surface 90 is formed between the large-diameter hole section 121 and the small-diameter hole section 122. The end of the large-diameter post section 431 facing the small-diameter post section 432 is limited and fitted with the stepped surface 90. The large-diameter column segment 431 and the large-diameter hole segment 121 cooperate, as do the small-diameter column segment 432 and the small-diameter hole segment 122. This allows the guide post 43 to move more smoothly within the mounting hole 12, and also enables the stepped surface 90 to limit the movement of the large-diameter column segment 431, preventing the guide post 43 from detaching from the mounting hole 12 under the elastic force of the first elastic element 60. The height of the large-diameter hole segment 121 is greater than the height of the large-diameter column segment 431, and the large-diameter column segment 431 is located within the large-diameter hole segment 121. This arrangement allows the large-diameter column segment 431 to move within the large-diameter hole segment 121, thereby enabling the guide post 43 to move.

[0047] like Figures 8 to 10 As shown, in this embodiment, the first reinforcing rib 2 extends along the front-rear direction of the mine car body 1. The fixing device of the mine car body also includes a positioning member 100, which is disposed in the positioning groove 11. The positioning member 100 is disposed opposite to the clamping assembly 30. When the clamping assembly 30 is in the clamping position, the first reinforcing rib 2 is clamped between the positioning member 100 and the clamping assembly 30. The bottom of the mine car body 1 is also provided with a second reinforcing rib 3 connected to the first reinforcing rib 2. The second reinforcing rib 3 extends along the left-right direction of the mine car body 1. There is an angle between the first reinforcing rib 2 and the second reinforcing rib 3. The fixing device of the mine car body also includes an anti-detachment member 110, which extends along the front-rear direction of the mine car body 1. The anti-detachment member 110 is hinged to the support assembly 10 and hooked to the second reinforcing rib 3. With the combined action of the positioning component 100 and the clamping assembly 30, the first reinforcing rib 2 is clamped more stably, thereby securing the mine car 1 more securely. The anti-detachment component 110 and the second reinforcing rib 3 are hooked together, making the position of the mine car 1 more stable after it is placed on the support assembly 10. The first reinforcing rib 2 and the second reinforcing rib 3 have an included angle, allowing the positioning component 100, the clamping assembly 30, and the anti-detachment component 110 to fix the mine car 1 in different directions, thus improving the fixing effect of the mine car 1.

[0048] Specifically, the first reinforcing rib 2 includes multiple ribs spaced apart along the left-right direction of the mine car body; the positioning groove 11 includes multiple ribs, each corresponding to one of the first reinforcing ribs 2; the clamping assembly 30 includes multiple ribs, with at least one clamping assembly 30 in each positioning groove 11; and the positioning element 100 includes multiple ribs, with at least one clamping assembly 30 in each positioning groove 11, each corresponding to one of the positioning elements 100. In this embodiment, the first reinforcing ribs 2 and the second reinforcing ribs 3 are arranged perpendicularly, which gives the mine car body 1 better structural strength. Under the combined action of the clamping ribs and the positioning elements, the mine car body is less prone to shaking and deviating from its original position during maintenance.

[0049] Preferably, the clamping assembly 30 includes a limiting plate, a first clamping post, and a first connecting rod connected between the limiting plate and the first clamping post. Part of the first connecting rod is located within the first channel 20, part within the support assembly 10, and another part within the positioning groove 11. The limiting plate is disposed within the first channel 20 and engages with the side wall of the first channel 20 near the positioning groove 11. A second elastic element 70 is disposed between the limiting plate and the side wall of the first channel 20 near the positioning groove 11, and is sleeved on the outer surface of the first connecting rod. The positioning element 100 includes a second connecting rod and a second clamping post connected to the second connecting rod. The second clamping post is disposed at one end of the second connecting rod facing the clamping assembly 30, and the other end of the second connecting rod is connected to the side wall of the positioning groove 11. The second clamping column has an installation space. The positioning component 100 also includes a connecting column, which is set in the installation space and connected to the second connecting rod. The second clamping column is rotatably set on the connecting column, which facilitates the entry and exit of the first reinforcing rib from the positioning groove. The second clamping column includes at least two, and the two second clamping columns are symmetrically arranged on both sides of the connecting column with the second connecting rod as the axis.

[0050] It should be noted that, except for the limiting plate, the clamping assembly 30 can be the same as the positioning component 100. This makes the manufacturing cost of the clamping assembly 30 and the positioning component 100 lower, improves their versatility, and facilitates the entry and exit of the first reinforcing rib from the positioning groove.

[0051] In this embodiment, the anti-detachment component 110 includes an anti-detachment hook, and a magnet is embedded in the end of the anti-detachment hook facing the mine car body 1, so that the anti-detachment component 110 can fit more stably with the mine car body 1. The support assembly 10 includes a support base and a mounting base. The mounting base is fixedly mounted on the base 140, and the support base and the mounting base are hinged together. The positioning groove 11, the first channel 20, the clamping assembly 30, the switching component 40, the first elastic component 60, the fourth channel 13, and the fifth channel 14 are all provided on the support base. The anti-detachment component 110 is hinged to the side of the support base facing the leveling assembly 130.

[0052] like Figure 1, Figure 2 , Figure 6 , Figure 7 as well as Figure 9 As shown, in this embodiment, the fixing device for the mine car body further includes a limiting member 120. The limiting member 120 is spaced apart from the support assembly 10 and located on the side of the support assembly 10. The limiting member 120 engages with the side wall of the mine car body 1 for limiting. The limiting member 120 can limit the side wall of the mine car body 1, thereby making the position of the mine car body 1 more stable after it is placed on the support assembly 10.

[0053] Specifically, the limiting member 120 includes at least two, and multiple limiting members 120 are symmetrically arranged on both sides of the support assembly 10, with the same number of limiting members on both sides of the support assembly 10. The limiting member 120 includes a limiting seat, a sixth channel disposed in the limiting seat, a drive column, and a push rod. The push rod is located in the sixth channel, and the other part of the push rod extends out of the limiting seat toward the center line of the left and right sides of the mine car 1. The drive column is movably disposed on the limiting seat along the depth direction of the positioning groove 11. The sixth channel is disposed between the drive column and the push rod, and the sixth channel is filled with a drive source. The mine car 1 squeezes the drive column, and the drive column squeezes the drive source located in the sixth channel. The drive source drives the push rod to extend toward the side wall of the mine car 1 and cooperate with the side wall of the mine car 1 to push against it.

[0054] It should be noted that the limiting component 120 also includes a receiving space disposed within the limiting seat and a third elastic component connecting the bottom of the receiving space and the drive column. The drive column portion is disposed within the receiving space, which is also filled with a drive source. The drive source can be gas or hydraulic oil. A fourth elastic component is disposed between the side wall of the sixth channel facing the mine car 1 and the push rod, so that after the mine car 1 separates from the drive column, the push rod can move towards the interior of the limiting seat under the action of the fourth elastic component. The fourth elastic component is a fourth spring. There are multiple push rods and multiple fourth elastic components, each corresponding to a push rod. The multiple push rods are spaced apart along the front-rear direction of the mine car 1. A seventh channel is also disposed within the limiting seat, and each push rod communicates with the seventh channel.

[0055] In this embodiment, the push rod includes two parts. The third elastic element is a third spring, which allows the drive column to extend out of the limiting seat under the action of the third elastic element after the mine car body 1 separates from the drive column. This facilitates the limiting element 120 to limit the mine car body 1 when it is placed again. Specifically, the limiting element also includes a connecting seat, which is fixedly connected to the base. The limiting seat is hinged to the connecting seat, which allows the push rod to fit more stably against the side wall of the mine car body 1 when the mine car body 1 presses against the drive column. The hinge between the limiting seat and the connecting seat also allows the limiting seat to swing around the axis hinged to the connecting seat when the mine car body 1 presses against the drive column. This allows the push rod to swing towards the side wall of the mine car body 1, thereby providing a more effective pushing effect on the side wall of the mine car body 1. The bottom of the limiting seat is also provided with an injection port, which communicates with the receiving space to allow the drive source to enter the receiving space, the sixth channel, and the seventh channel. The inlet diameter is smaller than the accommodating space diameter to prevent the third elastic element from falling off. In the direction from the support assembly to the leveling assembly, the distance between the connecting seat and the base gradually decreases, and consequently the distance between the limiting seat and the base gradually decreases, allowing the limiting element to better fit against the side wall of the mine car.

[0056] like Figure 1 As shown, in this embodiment, the fixing device for the mine car body further includes a leveling component 130. The leveling component 130 and the support component 10 are spaced apart along the length of the mine car body 1. The leveling component 130 and the support component 10 can support the mine car body 1. The leveling component 130 can adjust the horizontal state of the mine car body 1, which facilitates the maintenance of the mine car body 1.

[0057] Specifically, the leveling component can easily level the welded surfaces of the mine car body, improving welding efficiency and avoiding delays in coal mining and transportation.

[0058] Preferably, the leveling assembly 130 includes multiple components, which are spaced apart along the length of the mine car body 1. Each leveling assembly 130 includes a driving component, a supporting component, and a guiding component. The first end of the driving component is hinged to a base, and the second end of the driving component is hinged to the supporting component. The supporting component has an mounting groove on its side facing the mine car body 1, and a first reinforcing rib 2 is inserted into the mounting groove and engages with it for positioning.

[0059] Specifically, the driving component is a hydraulic cylinder, and multiple hydraulic cylinders are spaced apart along the width direction of the mine car body 1. The supporting component includes a supporting plate, with a mounting groove located on the side of the supporting plate away from the base. The guiding component includes a guide cylinder and a sliding cylinder, and multiple guiding components are spaced apart along the width direction of the mine car body 1. The sliding cylinder is partially nested within the guide cylinder and connected to the supporting plate. The hydraulic cylinder drives the supporting plate to move horizontally, and the guide cylinder and sliding cylinder provide guidance for the movement of the supporting plate. In the direction from the supporting component to the leveling component, the distance between the centerline of the guide cylinder and the supporting component 10 gradually increases, and the outer shape of the sliding cylinder fits against the inner wall of the guide cylinder. This allows the guide cylinder and sliding cylinder to more effectively guide the supporting plate to be level. Both the driving component and the guiding component include multiple components spaced apart along the left and right directions of the mine car body 1. This allows the driving component to also provide support for the supporting plate, distributing the weight of the mine car body and avoiding concentrated stress that could affect the normal use of the driving component and the guiding component.

[0060] It should be noted that a reinforcing plate is also provided between the guide cylinder and the base, which makes the force on the guide cylinder more even and prevents deformation during use. The guide cylinder is arc-shaped with a rectangular cross-section. The axis of the guide cylinder is coaxial with the hinge axis of the support base and the mounting base. This makes the overall force on the fixing device of the mine car 1 more reasonable when the leveling assembly adjusts the position of the mine car 1, and also allows the sliding cylinder to rotate around the hinge axis of the support base and the mounting base, thereby enabling rapid leveling of the mine car 1. The sliding cylinder includes multiple nested sliding cylinders with different external dimensions but the same wall thickness, which gives the guide component better structural strength.

[0061] like Figure 1 As shown, in this embodiment, the fixing device for the mine car body further includes a base 140, on which a traveling mechanism 141 is provided. The support assembly 10, the limiting member 120, and the leveling assembly 130 are all disposed on the base 140. The base 140 makes the positions of the support assembly 10, the limiting member 120, and the leveling assembly 130 more stable. The traveling mechanism 141 allows the fixing device for the mine car body to be moved to more positions, improving the versatility of the fixing device for the mine car body.

[0062] Specifically, the walking mechanism 141 includes multiple AGV steering wheels. In this embodiment, there are four AGV steering wheels, located at the four corners of the bottom of the base 140, allowing the base 140 to move freely in all directions. Preferably, the fixing device for the mine car body further includes a pulling member. The pulling member includes a connecting plate and a protruding edge connected to the connecting plate. The protruding edge extends towards the mine car body and hooks with the second reinforcing rib 3 to prevent the mine car body from falling off. Multiple pulling members are provided, spaced apart along the left-right direction of the mine car body 1 on the side of the support base away from the leveling component 130. The connecting plate is hinged to the side of the support base away from the leveling component 130.

[0063] It should be noted that the fixing device of the mine car has a first working state in which the side of the mine car containing the goods is located away from the base, and a second working state in which the side of the mine car containing the goods faces the base. A third reinforcing rib is also provided on the mine car, which is arranged around the side wall of the mine car. The mine car includes a holding section and an extension section connected to the holding section. The holding section is located at the rear of the mine car, and the extension section is also located at the rear of the mine car. The side of the support assembly facing the leveling assembly abuts against the side wall of the holding section, making the position of the mine car more stable.

[0064] like Figure 8 As shown, in this embodiment, when the fixing device of the mine car body is in the first working state, the anti-detachment component 110 hooks and engages with the second reinforcing rib 3, the first reinforcing rib 2 of the mine car body 1 is located in the positioning groove 11, the support assembly 10, the leveling assembly 130, and the anti-detachment component 110 are in contact with the mine car body 1, the opening of the mine car body faces away from the base, and the distance between the top of the mine car body and the base gradually decreases. Specifically, the working process of fixing the mine car body 1 to the fixing device of the mine car body is as follows:

[0065] 1. The first reinforcing rib 2 presses the guide post 43, and the guide post 43 moves away from the positioning groove 11. The second channel 41, the fourth channel 13, and the first channel 20 are connected. The power source enters the first channel 20, and the first clamping post moves towards the first reinforcing rib 2, and together with the positioning member 100, clamps the first reinforcing rib 2.

[0066] 2. The first reinforcing rib 2 contacts the mounting groove, and the driving component drives the support plate to move along the center line of the guide cylinder, so that the distance between the support plate and the base gradually increases until the horizontal position of the mine car body is adjusted.

[0067] 3. The anti-detachment component 110 is hooked onto the second reinforcing rib 3 to prevent the mine car body 1 from falling off.

[0068] When the fixing device of the mine car body is in the first working state, the process of disassembling the mine car body 1 from the fixing device is as follows:

[0069] 1. The anti-detachment component 110 separates from the second reinforcing rib 3;

[0070] 2. The first reinforcing rib 2 no longer presses against the guide post 43. Under the action of the first elastic member 60, the guide post 43 moves toward the direction close to the positioning groove 11. Under the action of the second elastic member 70, the first clamping post moves toward the first channel 20 and separates from the first reinforcing rib 2.

[0071] 3. The first channel 20, the third channel 42, and the fifth channel 14 are connected. The hydraulic oil leaves from the fifth channel 14 and flows back to the hydraulic station.

[0072] 4. The first reinforcing rib 2 detaches from the mounting groove, and the driving component drives the support plate to move along the centerline of the guide cylinder.

[0073] This gradually reduces the distance between the support plate and the base.

[0074] like Figure 9 As shown, in this embodiment, when the fixing device of the mine car body is in the second working state, the pulling member hooks and engages with the second reinforcing rib 3, and the support assembly 10, the leveling assembly 130, and the anti-detachment member 110 contact the mine car body 1. The opening of the mine car body 1 faces the base. The specific working process of fixing the mine car body 1 to the fixing device of the mine car body is as follows:

[0075] 1. The pulling component is hooked onto the second reinforcing rib 3 to prevent the mine car body 1 from falling off;

[0076] 2. The side wall of the mine car 1 presses the drive column, and the drive column moves away from the mine car 1. The drive source is pressed in the accommodating space, the sixth channel and the seventh channel. The push rod extends towards the side wall of the mine car 1 and pushes the mine car 1 to make the mine car 1 centered, thereby fixing the mine car 1.

[0077] 3. When the mine car body 1 comes into contact with the support plate, the driving component drives the support plate to move along the center line of the guide cylinder, so that the distance between the support plate and the base gradually increases until the horizontal position of the mine car body 1 is adjusted.

[0078] When the fixing device of the mine car is in the second working state, the process of disassembling the mine car from the fixing device is as follows:

[0079] 1. The pull member separates from the second reinforcing rib 3;

[0080] 2. The side wall of the mine car body 1 no longer presses against the drive column, the drive column no longer presses against the drive source in the accommodating space, the sixth channel and the seventh channel, the drive column moves toward the mine car body 1 under the action of the third elastic element, and the push rod moves away from the mine car body 1 under the action of the fourth elastic element, and separates from the mine car body 1.

[0081] 3. The mine car body 1 is separated from the fixed device of the mine car body, and the driving component drives the support plate to move along the center line of the guide cylinder, so that the distance between the support plate and the base gradually decreases.

[0082] It should be noted that, Figure 8 and Figure 9 The front, back, left, and right in the text refer to the front, back, left, and right sides of the mine car.

[0083] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0084] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0085] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0086] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
