Description

Technical Field

[0001] This utility model relates to the field of vehicle frames, and in particular to a frame structure and a mining car. Background Technology

[0002] Mining dump trucks are crucial transportation tools in mining and mountainous areas, operating in extremely harsh environments with rugged, steep, and sandy roads. In such conditions, the structural strength of the vehicle's frame directly determines its service life and operational safety and reliability. Currently, mining dump truck frames on the market primarily employ two design methods: integral casting and single-plate box-type welding. Because of their integrated fixing method, the splicing points are complex, and the weld lines are dense, resulting in high subsequent inspection and maintenance costs.

[0003] Currently, Chinese invention patent CN210363517U, published on April 21, 2020, proposes a hydraulic cylinder support and a wide-body dump truck. The hydraulic cylinder support, made of steel plate, includes a base plate and side plates welded to the two long sides of the base plate and perpendicular to it. The two side plates are parallel to each other. The base plate is a bent plate with an upward arch in the middle. Each side plate has mounting holes in the middle for fixing the lower support of the hydraulic cylinder. Support mounting holes are located at both ends of the base plate. In use, the bending moment stress borne by the load is converted into compressive stress, forming an "arch bridge" structure that supports the entire hydraulic cylinder support.

[0004] Regarding the aforementioned technologies, the hydraulic cylinder support is designed for small-tonnage mining vehicles. This hydraulic cylinder support undergoes deformation to a certain extent during operation. However, in larger-tonnage mining vehicles, the loading and unloading of materials generates a large amount of bumping and impact forces on the hydraulic cylinder support, which can easily cause deformation of the hydraulic cylinder support, resulting in overall displacement of the bottom end of the hydraulic cylinder and affecting its normal use. Utility Model Content

[0005] In order to improve the overall strength of the test bench and thus enhance its impact resistance under load, this utility model provides a test bench structure and a mining car.

[0006] In a first aspect, this utility model provides a platform structure, which adopts the following technical solution:

[0007] A platform structure includes a cylinder bracket, the cylinder bracket including a first top plate, a first vertical plate and a first bottom plate;

[0008] Two first upright plates are fixedly connected to the first base plate. The first upright plate extends a buffer portion along the length direction of the first upright plate, and the middle part of the buffer portion extends a protrusion in the opposite direction of the installation direction of the first upright plate.

[0009] The protrusion is used to fix the mounting base, and the mounting base is used to fix the hydraulic cylinder.

[0010] The two first top plates are respectively located at both ends of the protrusion. The first top plate includes a connecting portion, and an extension portion extends from one end of the connecting portion near the protrusion.

[0011] The connecting part is fixedly connected to the buffer part, and the extension part is bent upward and laid on the side of the protrusion.

[0012] By adopting the above technical solution, the two first upright plates fix the mounting base, and the bottom end of the mounting base can be placed on the first base plate, realizing the mounting base is fixedly installed using the first upright plates at both ends and the first base plate at the bottom; most mine car cargo boxes use a hydraulic cylinder, and the other end of the cargo box is hinged to the frame at two points. With the addition of the hydraulic cylinder, a three-point support is formed. When the hydraulic cylinder is under force, the first upright plate receives the impact load. Since the first upright plate is a single long plate, it can evenly distribute the load, making the stress distribution more uniform. Specifically, the mechanical analysis shows that the impact loads received by the protrusion from multiple directions are transmitted to the connecting part of the first top plate through the extension. At the same time, the protrusion transmits most of the impact load to the long sides of the first upright plates at both ends of the protrusion. With the connection and cooperation between the long sides and the connecting part, the stress on the long side of the first upright plate is distributed evenly. The uniform distribution and higher strength reduce the possibility of excessive local stress caused by impact loads, thereby improving the overall impact resistance. Simultaneously, the extension of the first top plate is welded to the protrusion of the first vertical plate to form a transition section, which effectively absorbs both vertical and longitudinal loads of the first vertical plate. Furthermore, the extension fixes the inclined sides at both ends to the first vertical plate, creating an effective tension connection and enhancing the first vertical plate's resistance to load impacts in the vehicle's travel direction. Additionally, the first bottom plate provides further effective support to the first vertical plate in both the vertical and travel directions, forming a stable box structure among the first vertical plate, first bottom plate, and first top plate. This improves the overall rigidity of the cylinder bracket, enhances its impact load resistance, and ultimately increases the strength of the platform.

[0013] Optionally, the side of the protrusion is set at a certain angle to the top of the protrusion, and the part where the side of the protrusion meets the top of the buffer is set in an arc shape.

[0014] By adopting the above technical solution, the sides of the protrusion are inclined, so that the extension fits with the protrusion, which can enhance the shear resistance and adapt to the force in different directions; the arc transition structure can effectively reduce stress concentration at the corner and extend fatigue life; at the same time, the first top plate and the first vertical plate are fixedly connected along the length direction, and the arc transition section makes the stress distribution more uniform. The first top plate can evenly distribute the lateral (length direction) impact load on the first vertical plate to the first top plate, which further improves the overall rigidity of the cylinder bracket and the ability to resist impact loads.

[0015] Optionally, two mounting seats are provided. Each mounting seat includes a base body, side uprights, a fourth top plate, and a fourth bottom plate. The base body has mounting openings. The two side uprights are fixedly installed at opposite ends of the base body. The fourth top plate is installed at the top of the base body, and the fourth bottom plate is installed at the bottom of the base body. The two mounting seats are arranged opposite each other, and the hydraulic cylinder is installed through the two opposite mounting openings. The mounting seats are fixedly connected to the adjacent first uprights through the side uprights by bolts.

[0016] By adopting the above technical solution, the two mounting seats are rotated and fixed to the bottom of the hydraulic cylinder through the mounting port, allowing the hydraulic cylinder to rotate at a certain angle; the fourth top plate rests on the top of the first vertical plate, and the fourth bottom plate abuts against the top of the first bottom plate. At the same time, multiple bolts are used to fix the side vertical plate to the first vertical plate, thereby forming a stable box structure. This makes the mounting seat and the adjacent first vertical plate and first bottom plate form a stable whole. The first vertical plate can effectively pull and fix the side vertical plate, and the first vertical plate can stably support the fourth top plate, which greatly improves the installation strength of the mounting seat, reduces the possibility of deformation or cracking of the hydraulic cylinder bracket, and enables it to withstand load impacts from multiple directions.

[0017] Optionally, the cylinder bracket further includes a plurality of first stiffening plates and a plurality of second stiffening plates;

[0018] The two sides of the first stiffening plate are respectively fixedly connected to one of the first upright plates, and the bottom end of the first stiffening plate is fixedly connected to the first base plate.

[0019] The second stiffening plate is fixedly connected to both the first vertical plate and the first top plate.

[0020] By adopting the above technical solution, the first stiffening plate fixes and connects the first upright plates at both ends, and at the same time, the bottom of the first stiffening plate is fixed to the first base plate. A stable support structure is formed between the first stiffening plate, the first upright plate and the first base plate at one corner of the first stiffening plate, which further improves the deformation resistance of the first upright plate. The second stiffening plate fixes and connects the first top plate and the first upright plate, which improves the connection strength of the long side of the first upright plate and the first top plate.

[0021] Optionally, the cylinder bracket further includes a mounting bracket, which includes a fixing plate, a support plate, and a connecting plate;

[0022] At least one of the support plates has its first end fixedly connected to the fixing plate, and at least one of the support plates has its second end fixedly connected to the connecting plate. The connecting plate is fixedly connected to the side end of the frame. The fixing plate has a welding port, and the fixing plate is fixedly connected to the upper end of the frame through the welding port. The bottom end of the first base plate is fixedly connected to the fixing plate.

[0023] By adopting the above technical solution, the mounting bracket supports the first base plate, and the fixing plate is fixedly connected to the first base plate, which can be fixed with bolts. The fixing plate supports the bottom of the first base plate, improving the vertical support capacity of the first base plate. Using bolts to fix the fixing plate to the first base plate reduces the possibility of lateral or longitudinal displacement of the first base plate. The surfaces of the first base plate and the fixing plate can rub against each other, thereby offsetting some of the shear stress. This allows the cylinder bracket to withstand greater longitudinal or lateral impact loads, as well as tensile forces on the first base plate. The fixing plate effectively supports the first base plate, improving its support capacity, and thus enhancing the support capacity of the first base plate for the long side of the first vertical plate. Further improvements are made to reduce the possibility of bending deformation of the first upright plate. Multiple welding joints are provided on the fixing plate, and a part of the fixing plate is welded to the frame through these joints, which improves the stability of the fixing plate. The bottom end of the other part of the fixing plate is fixedly connected to the support plate. Multiple support plates support the fixing plate, further improving its support capacity and allowing the bottom of the first base plate to have a larger bearing area, thus improving the support effect. The support plate is fixedly connected to the side of the frame through the connecting plate, which can be fixed by welding. By using the mutual fixing of the top and side surfaces of the frame, the shear stress between the fixed connections is greatly reduced to a certain extent, which can achieve effective support in the vertical direction while providing longitudinal and transverse tension support.

[0024] Optionally, the platform structure further includes a platform bracket and a support;

[0025] One end of the first upright plate is fixedly connected to multiple platform brackets, and the two ends of the vehicle frame are fixedly mounted with brackets.

[0026] The platform bracket includes a second top plate and a second vertical plate. The two ends of the second top plate are bent inward to form a bent portion. At least one of the second vertical plates is fixedly installed at the bottom end of the second top plate, and the second vertical plate is fixedly connected to the bent portion.

[0027] One of the bends of the second top plate is fixedly connected to the first upright plate, and the other bend of the second upright plate is fixedly connected to the bracket.

[0028] By adopting the above technical solution, the bracket and platform support are fixedly connected. The platform support then provides longitudinal (vehicle length direction) support for the first upright plate. Multiple rows of platform supports further enhance the longitudinal support strength of the first upright plate. Currently, during loading and unloading or when the vehicle is in a lifted cargo box state, the hydraulic cylinder support bears primarily longitudinal impact forces. By effectively supporting the first upright plate longitudinally using platform supports and brackets, the support effect and tensile and compressive strength are further improved, reducing the possibility of deformation and cracking of the hydraulic cylinder support and extending its service life. This ensures that the hydraulic cylinder support effectively supports the cylinder throughout the vehicle's lifespan, reducing maintenance costs. The spacing between multiple platform supports can be adjusted according to the location of other components mounted on top of the platform support. The installation position of the platform support between the first upright plate and the bracket can be adjusted according to assembly requirements, improving the installation flexibility of the platform support.

[0029] Optionally, the bracket includes a third upright plate, a third top plate, a bent plate, and a third stiffening plate. Two of the third upright plates are fixedly installed at the bottom end of the third top plate, and at least one of the third stiffening plates is simultaneously fixedly connected to both the third upright plate and the third top plate. The first end of the bent plate is simultaneously fixedly connected to both the third upright plate and the third top plate, and the second end of the bent plate is simultaneously fixedly connected to both of the third upright plates. The bent plate is also fixedly connected to the vehicle frame. One of the third upright plates is fixedly connected to the bent portion.

[0030] By adopting the above technical solution, the third upright plate is used to bear the load impact transmitted from the platform bracket. The stable box structure formed by the third upright plate, the third top plate, and the third stiffening plate can effectively improve the overall strength of the platform and its impact resistance, thereby providing more effective longitudinal support for the cylinder bracket. One end of the bent plate is fixed to the frame, and the other end can be further fixed to the frame using a mounting bracket. The bent plate can effectively fix and support the third upright plate, and at the same time, it can also be fixed to the third top plate, providing tension to the third top plate and improving the overall bending resistance of the platform. The platform and multiple platform brackets form a support platform, which is set at both ends of the frame. After installing other accessories on the support platforms at both ends, the strength between the platform bracket and the platform can be further improved to a certain extent, further improving the support effect for the cylinder bracket. At the same time, when the cylinder bracket is subjected to the impact force from top to bottom in the vertical direction, the platform bracket and the platform have a certain load after installing other accessories, thereby improving the impact resistance of the cylinder bracket.

[0031] Optionally, the first top plate has multiple openings; the fixing plate has multiple threaded holes, and a portion of the threaded holes are located below the openings.

[0032] By adopting the above technical solution, an installation opening is made on the first top plate, which makes it easier to pass through the opening and fix the first bottom plate and the fixed plate with bolts, thus improving the fixing effect. Without the opening, the first bottom plate and the fixed plate can only be fixed with bolts to the part of the fixed plate that extends relative to the frame, which is not a good fixing effect. Adding the opening allows more bolts to be fixed between the first bottom plate and the fixed plate, further improving the strength of the cylinder bracket.

[0033] Optionally, the cylinder bracket further includes a fourth rib plate, which is fixedly connected to the first vertical plate, the first top plate, and the first bottom plate, and is located below the mounting opening.

[0034] By adopting the above technical solution, the cylinder bracket at the mounting port is fixed by the fourth stiffening plate. After the mounting port is opened, the strength of the extension is improved. At the same time, the overall strength is further improved by fixing mounting bolts on both sides of the fourth stiffening plate.

[0035] Optionally, two mounting seats are provided. Each mounting seat includes a base body, side uprights, a fourth top plate, and a fourth bottom plate. The base body has mounting openings. The two side uprights are fixedly installed at opposite ends of the base body. The fourth top plate is installed at the top of the base body, and the fourth bottom plate is installed at the bottom of the base body. The two mounting seats are arranged opposite each other, and the hydraulic cylinder is installed through the two opposite mounting openings. The mounting seats are fixedly connected to the adjacent first uprights through the side uprights.

[0036] By adopting the above technical solution, the two mounting seats are rotated and fixed to the bottom of the hydraulic cylinder through the mounting port, allowing the hydraulic cylinder to rotate at a certain angle; the fourth top plate rests on the top of the first vertical plate, and the fourth bottom plate abuts against the top of the first bottom plate. At the same time, multiple bolts are used to fix the side vertical plate to the first vertical plate, thereby forming a stable box structure. This makes the mounting seat and the adjacent first vertical plate and first bottom plate form a stable whole. The first vertical plate can effectively pull and fix the side vertical plate, and the first vertical plate can stably support the fourth top plate, which greatly improves the installation strength of the mounting seat, reduces the possibility of deformation or cracking of the hydraulic cylinder bracket, and enables it to withstand load impacts from multiple directions.

[0037] Secondly, this utility model provides a mining car, which adopts the following technical solution:

[0038] A mining car includes a platform structure as described in the first aspect, and a frame, wherein the cylinder bracket is fixedly mounted on the frame, and the brackets are respectively fixedly mounted at both ends of the frame, and the brackets are fixedly connected to the adjacent cylinder brackets through the platform bracket.

[0039] By adopting the above technical solution, the bracket and platform support provide fixed support for the cylinder bracket, thereby improving the overall strength of the cylinder bracket and extending its service life.

[0040] In summary, this utility model has at least one of the following beneficial technical effects:

[0041] 1. The mine car cargo box is stably installed by combining the mounting base with the first vertical plate and the first bottom plate, forming a stable box structure. A single hydraulic cylinder and two hinged points to the frame constitute a three-point support, ensuring stability under hydraulic cylinder load. The first vertical plate evenly distributes the load, optimizing stress distribution; the welded transition section between it and the first top plate effectively absorbs loads from all directions. The extension section enhances the impact resistance of the first vertical plate, and the first bottom plate provides additional support, jointly improving structural rigidity and impact resistance, and enhancing the strength and reliability of the frame.

[0042] 2. The mounting bracket provides stable support to the first base plate via a fixing plate, which is bolted together to enhance the vertical support and resistance to lateral and longitudinal displacement of the first base plate. The fixing plate is connected to the frame through multiple welded joints and further reinforced by support plates, improving the overall structural stability and load-bearing capacity. This design not only reduces the risk of deformation of the first base plate and the first upright plate but also effectively offsets shear stress, enabling the cylinder bracket to withstand greater impact loads and tensile forces, achieving comprehensive support in the longitudinal, lateral, and vertical directions.

[0043] 3. The two mounting seats achieve rotational fixation of the bottom end of the hydraulic cylinder through the mounting port, forming a stable box structure with the first vertical plate and the bottom plate, which enhances the overall stability and multi-directional load bearing capacity, while reducing the risk of deformation.

[0058] Example 1:

[0059] This utility model discloses a stand structure. (Refer to...) Figures 1 to 8 A frame structure mainly includes a cylinder bracket 100, which includes a first top plate 101, a first vertical plate 102, and a first bottom plate 103. Two first vertical plates 102 are fixedly connected to the first bottom plate 103. A buffer portion 122 extends from the first vertical plate 102 along its length. A protrusion 104 extends from the middle portion of the buffer portion 122 in the opposite direction to the installation direction of the first vertical plate 102. The protrusion 104 is used to fix a mounting base 400, which fixes the cylinder. The two first top plates 101 are located at both ends of the protrusion 104. The first top plate 101 includes a connecting portion 121. An extension portion 105 extends from the end of the connecting portion 121 near the protrusion 104. The connecting portion 121 is fixedly connected to the buffer portion 122. The extension portion 105 is bent upward and laid on the side of the protrusion 104.

[0060] Two first upright plates 102 fix the mounting base 400. The bottom end of the mounting base 400 can be placed on the first base plate 103, so that the mounting base 400 can be fixedly installed by the first upright plates 102 at both ends and the first base plate 103 at the bottom. Most mine car cargo boxes use a hydraulic cylinder. The other end of the cargo box is hinged to the frame 700 at two points. With the addition of the hydraulic cylinder, a three-point support is formed. When the hydraulic cylinder is under force, the first upright plate 102 receives the impact load. Since the first upright plate 102 is a whole long plate, the first upright plate 102 can evenly distribute the load, making the stress distribution more uniform.

[0061] The specific mechanical analysis shows that the impact loads received by the protrusion 104 from multiple directions are transmitted to the connecting part 121 of the first top plate 101 through the extension part 105. At the same time, the protrusion 104 transmits most of the impact loads to the buffer parts 122 of the first vertical plate 102 at both ends of the protrusion 104. With the connection and cooperation between the buffer part 122 and the connecting part 121, the stress distribution of the buffer part 122 of the first vertical plate 102 is uniform and the strength is higher, thereby reducing the possibility of excessive local stress caused by impact loads and improving the overall impact resistance. Therefore, it can be used for mine cars with larger tonnages and is not prone to deformation or cracking. Meanwhile, the extension 105 of the first top plate 101 is welded to the protrusion 104 of the first vertical plate 102 to form a transition section, which can absorb both vertical loads and loads along the length of the first vertical plate 102. At the same time, the extension 105 fixes the first vertical plates 102 at both ends, forming an effective connection and improving the ability of the first vertical plate 102 to withstand load impacts in the driving direction of the frame 700. Meanwhile, the first bottom plate 103 can further provide effective support for the first vertical plate 102 in the vertical and driving directions, so that the first vertical plate 102, the first bottom plate 103, and the first top plate 101 form a stable box structure, which improves the overall rigidity of the cylinder bracket 100, enhances the cylinder bracket 100's resistance to impact loads, and thus improves the strength of the bracket 300.

[0062] Reference Figure 2 In some embodiments, the side of the protrusion 104 is set at a certain angle to the top of the protrusion 104, and the part where the side of the protrusion 104 meets the top of the buffer 122 is set in an arc shape.

[0063] The protrusion 104 has an inclined side, which allows the extension 105 to fit snugly against the protrusion 104, enhancing its shear resistance and adapting to forces in different directions. The arc-shaped transition structure effectively reduces stress concentration at corners and extends fatigue life. Meanwhile, the first top plate 101 and the first vertical plate 102 are fixedly connected along the length direction. The arc-shaped transition section makes the stress distribution more uniform. The first top plate 101 can evenly distribute the lateral (length direction of the frame 700) impact load on the first vertical plate 102 to the first top plate 101, further improving the overall rigidity of the cylinder bracket 100 and enhancing its resistance to impact loads.

[0064] In some embodiments, the side of the protrusion 104 and the top of the protrusion 104 are set at a certain angle. This angle can be selected in the range of 120° to 160°. For example, a preferred angle can be 140°. Within this angle range, the extension 105 and the protrusion 104 can have good mechanical properties, which can better transfer the load to the adjacent components, thereby improving the strength of the cylinder bracket 100.

[0065] In some embodiments, the width of the first top plate 101 along the vehicle's driving direction is greater than the distance between the two relative first upright plates 102, and the protruding long side of the first top plate 101 relative to the first upright plate 102 forms a welding angle with the first upright plate 102. This facilitates welding of the first top plate 101 and also provides a connecting effect on the long side of the first upright plate 102. The length of the protruding portion 104 of the first upright plate 102 is less than the length of one end of the long side of the first upright plate 102. By connecting the long side of the first upright plate 102 through the first top plate 101, the supporting capacity of the first upright plate 102 is improved, while reducing the possibility of deformation of the long side of the first upright plate 102.

[0066] Reference Figure 4 and Figure 5 In some embodiments, the cylinder bracket 100 further includes multiple first stiffening plates 106 and multiple second stiffening plates 107; the two sides of the first stiffening plate 106 are respectively fixedly connected to a first upright plate 102, and the bottom end of the first stiffening plate 106 is fixedly connected to a first base plate 103; the second stiffening plate 107 is fixedly connected to both the first upright plate 102 and the first top plate 101. The first stiffening plate 106 fixes and pulls the first upright plates 102 at both ends, and at the same time, the bottom of the first stiffening plate 106 is fixed to the first base plate 103. A stable support structure is formed between the first stiffening plate 106, the first upright plate 102 and the first base plate 103 at one corner of the first stiffening plate 106, further improving the deformation resistance of the first upright plate 102; the second stiffening plate 107 fixes the first top plate 101 and the first upright plate 102, improving the connection strength of the long side portion of the first upright plate 102 and the first top plate 101.

[0067] Reference Figure 5 In some embodiments, an opening 601 is provided in the middle of the first stiffening plate 106, and the two sides formed by the opening 601 of the first stiffening plate 106 are set at a certain angle to the first upright plate 102. The opening 601 facilitates the installation of the mounting base 400, does not affect the rotation range of the tool for fixing the bolts when fixing the mounting base 400; while ensuring installation strength, it saves some material usage and reduces the burden on the overall weight of the cylinder bracket 100.

[0068] Reference Figures 1 to 4 In some embodiments, the cylinder bracket 100 further includes a mounting bracket 110, which includes a fixing plate 111, a plurality of support plates 112, and a connecting plate 114; the first end of the support plate 112 is fixedly connected to the fixing plate 111, the second end of the support plate 112 is fixedly connected to the connecting plate 114, and the connecting plate 114 is fixedly connected to the side end of the frame 700; a welding port 113 is provided on the fixing plate 111, and the fixing plate 111 is fixedly connected to the upper end of the frame 700 through the welding port 113; the bottom end of the first base plate 103 is fixedly connected to the fixing plate 111.

[0069] The mounting bracket 110 supports the first base plate 103 and is fixedly connected to the first base plate 103 by a fixing plate 111, which can be fixed by bolts. The fixing plate 111 supports the bottom of the first base plate 103, improving the vertical support capacity of the first base plate 103. By fixing the fixing plate 111 to the first base plate 103 with bolts, the possibility of lateral or longitudinal displacement of the first base plate 103 is reduced. The surfaces of the first base plate 103 and the fixing plate 111 can rub against each other, thereby offsetting some of the shear stress. This allows the cylinder bracket 100 to withstand greater longitudinal or lateral impact loads and tensile forces on the first base plate 103.

[0070] The fixing plate 111 effectively supports the first base plate 103, improving the support capacity of the first base plate 103. This further enhances the support capacity of the first base plate 103 for the long side of the first upright plate 102, reducing the possibility of bending deformation of the first upright plate 102. The fixing plate 111 has multiple welding joints 113, which are used to weld a portion of the fixing plate 111 to the frame 700, improving the stability of the fixing plate 111.

[0071] The bottom end of another part of the fixed plate 111 is fixedly connected to the support plate 112. Multiple support plates 112 support the fixed plate 111, further improving the support capacity of the fixed plate 111. This allows the bottom of the first base plate 103 to have a larger bearing area, improving the support effect. By using the mutual fixing of the top and side surfaces of the frame 700, the shear stress between the fixed connections is greatly reduced to a certain extent. This enables effective support in the vertical direction while providing longitudinal and transverse tension support.

[0072] In some embodiments, friction surfaces are provided on the two surfaces of the fixing plate 111 and the first base plate 103 that come into contact with each other. By utilizing the friction surfaces, after the fixing plate 111 and the first base plate 103 are fixed, when they receive longitudinal or transverse loads, they can first consume part of the load energy through friction, reduce the shear stress on the fixing bolts, extend the service life of the fixing bolts, and thus extend the service life of the cylinder bracket 100.

[0073] In some embodiments, the first top plate 101 has a plurality of openings 108; the fixing plate 111 has a plurality of threaded holes 500, and some of the threaded holes 500 are located below the openings 108. The installation opening 402 on the first top plate 101 allows for easier passage through the openings 108, enabling bolts to be used to fix the first bottom plate 103 and the fixing plate 111, improving the fixing effect. Without the openings 108, the first bottom plate 103 and the fixing plate 111 can only be fixed by bolts to a portion of the fixing plate 111 extending relative to the frame 700, resulting in poor fixing. The addition of the openings 108 allows for the fixing of more bolts between the first bottom plate 103 and the fixing plate 111, further improving the overall strength of the cylinder bracket 100.

[0074] Reference Figure 2 In some embodiments, the thickness of the first upright plate 102 is greater than the thickness of the first top plate 101; the thickness of the first stiffening plate 106 is greater than the thickness of the first bottom plate 103; the thickness of the first bottom plate 103 is greater than the thickness of the second stiffening plate 107; and the thickness of the fixing plate 111 is greater than the thickness of the support plate 112.

[0075] The first upright plate 102 has a larger thickness, enabling it to bear a greater load in the vertical direction. Simultaneously, both longitudinal and lateral loads on the first upright plate 102 are first transferred to it. Therefore, the larger thickness of the first upright plate 102 provides better load-bearing capacity. Meanwhile, the first top plate 101 and the first bottom plate 103 have a smaller thickness than the first upright plate 102, which, to a certain extent, provides better load-bearing capacity while stabilizing and reinforcing the first upright plate 102. This also saves material costs, reduces the overall weight of the cylinder bracket 100, and improves fuel economy for the entire vehicle. The fixing plate 111 has a greater thickness than the support plate 112, giving it greater support capacity. This allows for better welding of the weld joint 113 and allows for longer bolts mounted on the fixing plate 111, thereby reducing shear stress and improving fixing strength.

[0076] Reference Figure 2 In some embodiments, a clearance opening 602 is provided on the first base plate 103, and the clearance opening 602 is located below the mounting base 400. By providing the clearance opening 602, the mounting base 400 can be equipped with various models of hydraulic cylinders. When using a larger model of hydraulic cylinder, the bottom edge of the cylinder will generate a swing amplitude range during the swinging process. By using the clearance opening 602, the possibility of the first base plate 103 obstructing the bottom of the cylinder is reduced, and some materials can be saved, reducing the overall weight of the hydraulic cylinder bracket 100.

[0077] Reference Figures 1 to 4 In some embodiments, the platform structure further includes a platform bracket 200 and a support 300;

[0078] One end of the first upright plate 102 is fixedly connected to multiple platform brackets 200, and the two ends of the frame 700 are fixedly mounted with brackets 300. The platform brackets 200 include a second top plate 201 and a second upright plate 202. The two ends of the second top plate 201 are bent inward to form bent portions 203. At least one second upright plate 202 is fixedly installed at the bottom end of the second top plate 201. The sides of both ends of the second upright plate 202 are fixedly connected to the bent portions 203 of the second top plate 201. One bent portion 203 of the second top plate 201 is fixedly connected to the first upright plate 102, and the other bent portion 203 of the second upright plate 202 is fixedly connected to the bracket 300. Multiple platform brackets 200 are provided between the cylinder bracket 100 and the bracket 300, and the spacing between the multiple platform brackets 200 can be adjusted by adjusting the mounting holes between the bracket 300 and the first upright plate 102 to achieve the spacing between two adjacent platform brackets 200.

[0079] The bracket 300 is fixedly connected to the platform bracket 200, and the platform bracket 200 supports the first upright plate 102 longitudinally (in the direction of vehicle length). Multiple rows of platform brackets 200 further support the first upright plate 102, improving its longitudinal support strength. Currently, when loading and unloading goods or during vehicle movement with the cargo box lifted, the load borne by the cylinder bracket 100 is primarily longitudinal impact force. By utilizing the platform bracket 200 and bracket 300 to effectively support the first upright plate 102 longitudinally, the longitudinal strength is further improved. The improved support effect and tensile and compressive strength reduce the possibility of deformation and cracking of the cylinder bracket 100, extending its service life. This ensures that the cylinder bracket 100 can effectively support the cylinder throughout the vehicle's service life, reducing maintenance costs. The spacing between the multiple platform brackets 200 can be adjusted according to the location of other accessories installed above the platform bracket 200. The installation position of the platform bracket 200 between the first upright plate 102 and the bracket 300 can be adjusted according to assembly requirements, improving the installation flexibility of the platform bracket 200.

[0080] Reference Figure 4 In some embodiments, the bracket 300 includes a third upright plate 301, a third top plate 302, a bent plate 303, and a third stiffening plate 304. Two third upright plates 301 are fixedly installed at the bottom end of the third top plate 302, and at least one third stiffening plate 304 is simultaneously fixedly connected to both the third upright plate 301 and the third top plate 302. The first end of the bent plate 303 is simultaneously fixedly connected to both the third upright plate 301 and the third top plate 302, and the second end of the bent plate 303 is simultaneously fixedly connected to both third upright plates 301. The bent plate 303 is also connected to the frame. 700 is fixedly connected; one of the third upright plates 301 is fixedly connected to the bent part 203 of the second top plate 201; the bent plate 303 is fixedly connected to the gantry and the oil spring seat of the frame 700 by bolts, which improves the stress state of the support 300, reduces the possibility of failure or damage caused by excessive shear force on a single set of bolts, improves the structural stability and reliability, makes the later inspection, maintenance and disassembly of the frame more convenient, thereby reducing the maintenance cost of the frame 700, improving the flexibility of the frame 700 and enhancing the product competitiveness.

[0081] The third upright plate 301 absorbs the impact load transmitted from the platform bracket 200. The stable box structure formed by the third upright plate 301, the third top plate 302, and the third stiffening plate 304 can effectively improve the overall strength of the platform structure and its impact resistance, thereby providing more effective longitudinal support for the cylinder bracket 100. One end of the bent plate 303 is fixed to the frame 700, and the other end can be further fixed to the frame 700 using a mounting bracket. The bent plate 303 can effectively fix and support the third upright plate 301, and at the same time, the bent plate 303 can also be fixed to the third top plate 302 and pulled together, improving the overall bending resistance of the platform structure.

[0082] The bracket and multiple platform brackets 200 surround each other to form a support platform. The support platforms are positioned opposite each other at both ends of the frame 700. After installing other accessories on the support platforms at both ends, the strength between the platform brackets 200 and the bracket 300 can be further improved to a certain extent, and the support effect on the cylinder bracket 100 can be further improved. At the same time, when the cylinder bracket 100 is subjected to the impact force from top to bottom in the vertical direction, the platform brackets 200 and the bracket 300 have a certain load after installing other accessories, which can improve the impact resistance of the cylinder bracket 100.

[0083] Reference Figure 6 In some embodiments, the first upright plate 102 has multiple mounting openings 402; the fixing plate 111 has multiple threaded holes 500, and some of the threaded holes 500 are located below the mounting openings 402. The mounting openings 402 on the first upright plate 102 facilitate the bolting of the first base plate 103 and the fixing plate 111, improving the fixing effect. Without the mounting openings 402, the first base plate 103 and the fixing plate 111 can only be fixed with bolts to a portion of the fixing plate 111 extending relative to the frame 700, resulting in poor fixing. The addition of mounting openings 402 allows for the fixing of more bolts between the first base plate 103 and the fixing plate 111, further improving the overall strength of the cylinder bracket 100.

[0084] Reference Figure 5 In some embodiments, the cylinder bracket 100 further includes a fourth stiffening plate 603, which is fixedly connected to the first upright plate 102, the first top plate 101, and the first bottom plate 103. This fixed connection can be achieved through welding, and the fourth stiffening plate 603 is located below the mounting opening 402. The fourth stiffening plate 603 secures the cylinder bracket 100 at the mounting opening 402. The opening 402 enhances the strength of the extension 105, and the presence of mounting bolts on both sides of the fourth stiffening plate 603 further improves the overall strength.

[0085] Reference Figure 6 In some embodiments, two mounting bases 400 are provided. Each mounting base 400 includes a base body 401, side uprights 403, a fourth top plate 404, and a fourth bottom plate 405. The base body 401 has mounting openings 402. The two side uprights 403 are fixedly mounted at both ends of the base body 401. The fourth top plate 404 is mounted at the top of the base body 401, and the fourth bottom plate 405 is mounted at the bottom of the base body 401. The two mounting bases 400 are arranged opposite to each other, and the hydraulic cylinder is mounted through the two opposite mounting openings 402. The mounting base 400 is fixedly connected to the adjacent first upright plate 102 through the side uprights 403.

[0086] Two mounting bases 400 are rotated and fixed to the bottom of the cylinder through mounting ports 402, allowing the cylinder to rotate at a certain angle. The fourth top plate 404 rests on the top of the first vertical plate 102, and the fourth bottom plate 405 abuts against the top of the first bottom plate 103. At the same time, multiple bolts are used to fix the side vertical plate 403 to the first vertical plate 102, thereby forming a stable box structure. This makes the mounting base 400 and the adjacent first vertical plate 102 and first bottom plate 103 form a stable whole. The first vertical plate 102 can effectively pull and fix the side vertical plate 403 and can stably support the fourth top plate 404, which greatly improves the installation strength of the mounting base 400, reduces the possibility of deformation or cracking of the cylinder bracket 100, and enables it to withstand load impacts from multiple directions.

[0087] Reference Figure 5 In some embodiments, the first upright plate 102 is provided with threaded holes 500 for fixing the first upright plate 102 to the mounting base 400 by bolts; the threaded holes 500 on the first upright plate 102 and the threaded holes 500 on the fixing plate 111 are both rectangular or elongated adjustable threaded holes 500. This allows for a certain degree of overall adjustment of the position of the cylinder bracket 100 in the vehicle width direction. When the cylinder bracket 100 shifts in the vehicle width direction (lateral), the position of the adjusting bolts in the bolt holes can be adjusted to correspondingly shift the cylinder bracket 100 in the vehicle width direction of the frame 700, restoring the bottom of the cylinder to its initial position. This reduces the need to replace the entire cylinder bracket 100, lowers maintenance costs, and improves flexibility.

[0088] In some embodiments, the cylinder bracket 100, platform bracket 200, and bracket 300 are all provided with multiple through holes. On one side of the frame 700, the platform bracket 200 and bracket 300 form an installation platform. The through holes provide the necessary conditions for the assembly of other vehicle accessories. At the same time, the arc-shaped through hole structure can effectively disperse local stress and avoid stress concentration. Furthermore, by rationally designing the size and distribution of the through holes, the self-weight can be reduced to the maximum extent while ensuring the strength and rigidity of the structure itself.

[0089] The implementation principle of a stand structure according to an embodiment of this utility model is as follows:

[0090] The mine car cargo box, combined with the mounting base 400, the first vertical plate 102, and the first bottom plate 103, forms a stable box structure. It utilizes a single hydraulic cylinder and two-point hinges to the frame 700 to achieve three-point support, ensuring stability under stress. The first vertical plate 102 optimizes stress distribution, and the welded transition section between it and the first top plate 101 absorbs loads from all directions. The extension 105 and the first bottom plate 103 together enhance impact resistance and structural rigidity, improving the strength and reliability of the structure 300. The mounting bracket 110 provides stable support to the first bottom plate 103 via the fixing plate 111. Bolted connections enhance vertical support and displacement resistance, and multiple welded joints 113 and support plates 112 further reinforce the structure, effectively reducing deformation risk and offsetting shear stress. This allows the hydraulic cylinder bracket 100 to withstand greater impact loads and tensile forces, achieving comprehensive support. For minor deformations, adjusting the assembly gap restores the position of the mounting base 400, reducing the impact on the hydraulic cylinder, thereby lowering costs and extending service life. The overall design improves structural stability and flexibility in dealing with practical problems, and enhances the overall strength and reliability of the test bench structure.

[0091] Example 2:

[0092] This utility model discloses a mining car. (Refer to...) Figure 1 A mining car mainly includes a frame structure as described in Embodiment 1, and includes a frame 700, a cylinder bracket 100 fixedly installed on the frame 700, and brackets 300 fixedly installed at both ends of the frame 700. The brackets 300 and the adjacent cylinder brackets 100 are fixedly connected through a platform bracket 200.

[0093] The bracket 300 and platform bracket 200 provide fixed support for the cylinder bracket 100, improving the overall strength of the cylinder bracket 100 and thus extending its service life; this also extends the service life of the entire vehicle. Therefore, the mining car can reduce maintenance frequency and costs while ensuring efficient operation, improving economic efficiency. In the face of minor deformation, the mounting seat 400 can be restored to its original position by adjusting the assembly clearance. This not only reduces the impact on the cylinder but also simplifies the maintenance process, lowers technical requirements, facilitates rapid on-site problem handling, and improves work efficiency.

[0094] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
