Description

Technical Field

[0001] This application relates to the field of coal mine transportation technology, and in particular to a multi-functional shovel and fork mechanism for an explosion-proof diesel loader in underground coal mines. Background Technology

[0002] The underground coal mine working environment is characterized by confined space, diverse material types (such as bulk coal, support steel sheds, and equipment parts), high dust concentration, and the need to meet explosion-proof requirements. As a core material transport equipment underground, the operational flexibility and adaptability of the front-end shovel mechanism directly determine the overall shoveling and transport efficiency. In actual production, underground operations need to simultaneously complete tasks such as bulk coal loading, transporting structural support components, and transferring faulty equipment, requiring different shoveling angles, shovel spacing, and shoveling heights.

[0003] In existing technologies, the fork mechanisms of explosion-proof diesel loaders in underground coal mines mostly adopt fixed spacing and single-dimensional adjustment. Specifically, some mechanisms rely solely on the loader's own hydraulic arm for longitudinal lifting, but the lateral spacing of the forks is fixed. When facing support steel sheds or coal boxes of different widths, it is necessary to stop the machine and replace the special fork assembly. Furthermore, the connecting rotating parts generally adopt a simple hinge structure, which lacks stability in coordination with the loader's fixed rotating shaft and rotating push rod. During operation, the rotation is prone to jamming due to coal dust accumulation, making it impossible to smoothly complete the continuous action of tilting and lifting for transport.

[0004] Therefore, it is necessary to improve one or more of the problems existing in the above-mentioned related technical solutions.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0010] In one possible implementation, the longitudinal adjustment assembly further includes a limiting rod that passes through both ends of the concave slide rail and is used to limit the sliding stroke of the slide plate.

[0011] In one possible implementation, the longitudinal adjustment assembly further includes a protective plate and a protective cover; the protective plate is fixedly connected to the top surface of the slide plate and the fourth connecting plate, and slidably connected to the first slide rail member, and the protective cover covers the third push rod.

[0012] In one possible implementation, the lateral adjustment assembly includes: a first mounting plate, a first connecting plate, an adjustment part, a first push rod, and a second push rod; The first mounting plate is fixedly connected to the slide plate; there are two first connecting plates, which are respectively fixedly connected to both sides of the first mounting plate; The adjustment part includes a first connecting shaft and a second connecting shaft. One end of the first connecting shaft and the second connecting shaft are respectively fixedly connected to the inner side of the two first connecting plates, and the other end is fixedly connected to the first mounting plate. The shovel fork assembly consists of two parts, which are slidably mounted on the first connecting shaft and the second connecting shaft, respectively. The first push rod and the second push rod are respectively mounted on the two first connecting plates, and their output ends are respectively fixedly connected to the two shovel fork assemblies. They are used to control the two shovel fork assemblies to slide on the first connecting shaft and the second connecting shaft by pushing out or retracting the first push rod and the second push rod.

[0013] In one possible implementation, the first connecting shaft and the second connecting shaft are fixedly connected to the first connecting plate and the first mounting plate via a connecting block; The lateral adjustment assembly further includes a second connecting plate, which is fixedly mounted on the first mounting plate and fixedly connected to the connecting block.

Through the cooperation of the rotating shaft connection of the rotating component with the fixed rotating shaft of the loader, and the push rod connection with the rotating push rod of the loader, stable rotation is achieved around the fixed rotating shaft as the rotation center. This drives the shovel and fork assembly to flexibly complete the core actions of flipping and scooping materials and lifting and transporting materials, solving the problems of rotational jamming and limited working angle in traditional shovel and fork mechanisms. Furthermore, the adjustment part on the front of the adjustment component allows direct longitudinal and / or lateral position adjustment of the shovel and fork assembly, adapting to bulk coal blocks of different stacking heights and regular materials of different widths in underground coal mines, eliminating the need for frequent replacement of dedicated shovel and transport components.

[0020] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, they are provided to make this application more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0021] Furthermore, the accompanying drawings are merely illustrative of this application and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and therefore, repeated descriptions of them will be omitted.

[0022] This example embodiment first provides a multi-functional shovel and fork mechanism for an explosion-proof diesel loader in underground coal mines. (Reference) Figure 1 As shown, the multi-functional shovel and fork mechanism for the explosion-proof diesel loader in the coal mine includes an adjustment component 100, a connecting rotation component 200, and a shovel and fork assembly 300.

[0023] The connecting rotating assembly 200 has a rotating shaft connecting part and a push rod connecting part on the rear side, which are respectively connected to the fixed rotating shaft and the rotating push rod at the front end of the underground explosion-proof diesel loader in the coal mine, and are used to rotate around the fixed rotating shaft as the rotation center when the rotating push rod is pushed out or retracted. The adjustment assembly 100 is connected at its rear to the side of the connecting rotation assembly 200 away from the explosion-proof diesel loader in the coal mine, and has an adjustment part at its front for adjusting the longitudinal and / or lateral position of the adjustment part; The fork assembly 300 is connected to the adjustment unit and is used for longitudinal and / or lateral position adjustment via the adjustment unit.

[0024] The aforementioned multi-functional shovel and fork mechanism for explosion-proof diesel loaders in underground coal mines can efficiently adapt to the complex material handling needs of underground coal mines by relying on the synergistic effect of the connecting rotating component 200, the adjusting component 100, and the shovel and fork assembly 300. Specifically, the connecting rotating component 200, with the fixed hook 230 as its rotation center, can smoothly achieve the core actions of "shovel and fork assembly 300 tilting downwards to scoop up materials" and "lifting upwards to transport materials" through the linkage of the third mounting plate 220 and the loader's rotating push rod, solving the problems of rotational jamming and poor operational continuity in traditional shovel and fork mechanisms. At the same time, the longitudinal adjustment component 120 drives the slide plate 122 to slide in the concave slide rail through the third push rod 121, which can drive the lateral adjustment component 110 and the shovel fork component 300 to move up and down or back and forth as a whole, adapting to bulk coal blocks and stacking equipment accessories with different stacking heights; the lateral adjustment component 110, with the independent control of the first push rod 114 and the second push rod 116, allows the two shovel fork components 300 to flexibly adjust the spacing along the first connecting shaft 113 and the second connecting shaft 115, which can accurately match materials of different widths such as supporting steel sheds and coal boxes, without the need for frequent replacement of special shovel fork parts.

[0025] In one embodiment, the adjustment component 100 includes a lateral adjustment component 110 and a longitudinal adjustment component 120; The lateral adjustment component 110 is connected to the connecting rotation component 200 via the longitudinal adjustment component 120, and the adjustment part is located on the lateral adjustment component 110; wherein, the longitudinal adjustment component 120 is used to adjust the longitudinal position of the lateral adjustment component 110, and the lateral adjustment component 110 is used to adjust the lateral position of the adjustment part.

[0026] It should be noted that the layered connection structure of the lateral adjustment component 110 and the longitudinal adjustment component 120 enables multi-dimensional position adjustment of the shovel fork assembly 300. The longitudinal adjustment component 120 can drive the lateral adjustment component 110 to move vertically or horizontally, while the lateral adjustment component 110 directly controls the left-right spacing adjustment of the shovel fork assembly 300 through its adjustment part. The coordinated operation of these two components allows the shovel fork assembly 300 to adapt to the shoveling and transporting needs of materials with different stacking heights and widths in underground coal mines, such as coal blocks, support steel sheds, and equipment accessories. This solves the problem of traditional shovel fork mechanisms only being able to adjust in one direction and having poor adaptability. Simultaneously, the adjustment part is integrated into the lateral adjustment component 110, ensuring that the adjustment action is accurately transmitted to the shovel fork assembly 300, avoiding deviation or jamming during adjustment. This ensures the comprehensiveness of the adjustment range while reducing the load on individual components through component separation.

[0027] In one embodiment, the longitudinal adjustment assembly 120 includes: a first slide rail 124, a second slide rail 125, a third push rod 121, a slide plate 122, and a fourth connecting plate 128; The first slide rail 124 is fixedly connected to the front side of the connecting rotation assembly 200 via the second slide rail 125, forming a concave slide rail; One end of the slide plate 122 is slidably disposed in the concave slide rail, and the other end is fixedly connected to the lateral adjustment component 110; The output end of the third push rod 121 is fixedly connected to the lateral adjustment assembly 110 through the fourth connecting plate 128.

[0028] It should be noted that one end of the second slide rail 125 is fixed to the connecting rotating assembly 200, and the other end is connected to the first slide rail 124. This ensures the connection strength between the concave slide rail and the connecting rotating assembly 200, preventing the concave slide rail from loosening when bearing the weight of the lateral adjustment assembly 110. The sliding cooperation between the slide plate 122 and the concave slide rail provides a stable track for the longitudinal movement of the lateral adjustment assembly 110. The concave structure can limit the vertical offset of the slide plate 122, ensuring accurate movement direction. The third push rod 121 is connected to the lateral adjustment assembly 110 through the fourth connecting plate 128, rather than directly. This is because the fourth connecting plate 128 can increase the thrust application area, preventing the output end of the third push rod 121 from being damaged due to excessive local force. At the same time, it allows the thrust to be evenly transmitted to the lateral adjustment assembly 110, preventing the lateral adjustment assembly 110 from tilting due to uneven force.

[0029] Furthermore, the longitudinal adjustment assembly 120 also includes a limiting rod 126, which passes through both ends of the concave slide rail and is used to limit the sliding stroke of the slide plate 122.

[0030] It should be noted that the limiting rod 126 passes through both ends of the concave slide rail, limiting the maximum sliding boundary of the slide plate 122. When the slide plate 122 moves to the end of the concave slide rail with the extension and retraction of the third push rod 121, it will be blocked by the limiting rod 126 to prevent the slide plate 122 from sliding out of the concave slide rail and causing the longitudinal adjustment component 120 to fail.

[0031] Optionally, the longitudinal adjustment assembly 120 further includes a protective plate 123 on a protective cover 127; the protective plate 123 is fixedly connected to the top surface of the slide plate 122 and the fourth connecting plate 128, and is slidably connected to the first slide rail 124, and the protective cover 127 covers the third push rod 121.

[0032] It should be noted that when the slide plate 122 slides in the concave slide rail, the protective plate 123 will move synchronously, always covering the top opening of the concave slide rail, preventing coal dust and gravel from falling into the slide rail from the mine, and avoiding blockage of the sliding gap, which would cause the slide plate 122 to jam. The protective cover 127 covers the third push rod 121, which can isolate the push rod piston rod and seals from the corrosion of coal dust, and at the same time prevent gravel from hitting the push rod body during operation, thus avoiding failures such as seal failure and piston rod deformation.

[0033] In one embodiment, the lateral adjustment assembly 110 includes: a first mounting plate 117, a first connecting plate 111, an adjustment part, a first push rod 114, and a second push rod 116; The first mounting plate 117 is fixedly connected to the slide plate 122; there are two first connecting plates 111, which are fixedly connected to both sides of the first mounting plate 117 respectively. The adjustment part includes a first connecting shaft 113 and a second connecting shaft 115. One end of the first connecting shaft 113 and the second connecting shaft 115 are respectively fixedly connected to the inner side of the two first connecting plates 111, and the other end is fixedly connected to the first mounting plate 117. There are two shovel fork assemblies 300, which are respectively slidably mounted on the first connecting shaft 113 and the second connecting shaft 115; The first push rod 114 and the second push rod 116 are respectively disposed on the two first connecting plates 111, and their output ends are respectively fixedly connected to the two shovel fork assemblies 300. They are used to control the two shovel fork assemblies 300 to slide on the first connecting shaft 113 and the second connecting shaft 115 by pushing out or retracting the first push rod 114 and the second push rod 116.

[0034] It should be noted that the first mounting plate 117 is the basic load-bearing component of the lateral adjustment assembly 110. By fixing it to the sliding plate 122, it enables the linkage between the lateral adjustment assembly 110 and the longitudinal adjustment assembly 120. The two symmetrically arranged first connecting plates 111 provide end fixing points for the first connecting shaft 113 and the second connecting shaft 115, and also provide mounting carriers for the first push rod 114 and the second push rod 116, ensuring the structural symmetry and force balance of the lateral adjustment assembly 110. The parallel arrangement of the first connecting shaft 113 and the second connecting shaft 115... The structure provides a stable sliding track for the shovel fork assembly 300, restricting the shovel fork assembly 300 to move only laterally, thus avoiding front-to-back offset during adjustment. The independent control design of the first push rod 114 and the second push rod 116 enables flexible adjustment of the two shovel fork assemblies 300. They can be extended or retracted simultaneously to maintain a constant distance, or one of them can be adjusted individually to increase or decrease the distance. For example, when moving a wide support steel beam, the two push rods can be controlled to extend synchronously to increase the distance, and when moving a narrow coal box, the push rods can be controlled to retract to decrease the distance, making it highly adaptable.

[0035] Optionally, the first push rod 114, the second push rod 116 and the third push rod 121 can be explosion-proof hydraulic push rods or explosion-proof pneumatic push rods, and also have a dustproof sealing design.

[0036] Furthermore, the first connecting shaft 113 and the second connecting shaft 115 are fixedly connected to the first connecting plate 111 and the first mounting plate 117 via a connecting block; The lateral adjustment assembly 110 further includes a second connecting plate 112, which is fixedly mounted on the first mounting plate 117 and fixedly connected to the connecting block.

[0037] It should be noted that the connecting blocks are designed to enhance the connection strength between the first connecting shaft 113, the second connecting shaft 115 and the first connecting plate 111 and the first mounting plate 117, improve the stability of the first connecting shaft 113 and the second connecting shaft 115, and ensure that the shaft does not wobble when the fork assembly 300 slides. Furthermore, the lateral adjustment assembly 110 also includes a first connecting frame 118, which is fixedly connected to the slide plate 122 and to the bottom surface of the first mounting plate 117.

[0038] It should be noted that, due to the setting of the first connecting frame 118, the top surface of the first mounting plate 117 needs to bear the weight of the first connecting plate 111, the adjustment part, the shovel fork assembly 300 and the material. After long-term use, it is prone to downward bending and deformation. The first connecting frame 118 provides upward support from the bottom surface, which can offset part of the load pressure and further improve the connection strength between the lateral adjustment assembly 110 and the longitudinal adjustment assembly 120, so that the lateral adjustment assembly 110 moves more synchronously with the slide plate 122 and reduces relative swaying.

[0039] Optionally, the first mounting plate 117 is fixedly connected to the slide plate 122 via the third connecting plate 119.

[0040] In one embodiment, the connecting rotation assembly 200 includes: a second mounting plate 210, a third mounting plate 220, a rotating shaft connecting portion, and a fourth mounting plate 250; The second mounting plate 210 is a U-shaped plate, and the fourth mounting plate 250 is fixedly connected to the lower part of the back of the second mounting plate 210, with its top flush with the U-shaped recess of the second mounting plate 210. There are four third mounting plates 220, which are fixedly connected to the second mounting plate 210 and the fourth mounting plate 250. Two opposite third mounting plates 220 have corresponding rotating shaft connection holes 221, which constitute the push rod connection part. The push rod connection part is used to be rotatably connected to the output end of the front rotating push rod of the coal mine explosion-proof diesel loader. The shaft connection part is a fixed hook 230, which is fixed to the top of the fourth mounting plate 250 and is used to connect with the fixed shaft at the front end of the underground explosion-proof diesel loader.

[0041] It should be noted that the U-shaped recess can accommodate the upper part of the fourth mounting plate 250, ensuring the fit between the fourth mounting plate 250 and the second mounting plate 210. At the same time, the two side plates of the U-shaped structure can enhance the overall bending resistance and withstand the impact force during the operation of the shovel fork mechanism. The grouping of the four third mounting plates 220, with each pair forming a push rod connection part, can form a stable rotatable connection with the output end of the front rotating push rod of the shovel.

[0042] Optionally, the connecting rotation assembly 200 further includes: a bottom support 240, which is fixedly disposed at the bottom of the second mounting plate 210, for supporting the fourth mounting plate 250 and the adjustment assembly 100.

[0043] It should be noted that the bottom support 240 is fixed to the bottom of the second mounting plate 210, providing bottom support for the fourth mounting plate 250. At the same time, the bottom support 240 can also improve the overall stability of the connecting rotating assembly 200, preventing it from swaying left and right during rotation.
