Abstract
Description
Technical Field
[0001] This utility model relates to the field of heavy machinery and equipment technology, and in particular to a fork structure for a tracked transport vehicle and the tracked transport vehicle itself. Background Technology
[0002] Tracked transport vehicles are a common type of heavy-duty tracked special mining vehicle. They are widely used in the relocation of heavy semi-continuous, continuous, and intermittent process equipment (such as semi-mobile crushing stations and belt conveyor drive stations) in large open-pit mines.
[0003] Existing tracked transport vehicles such as Figure 1 As shown, it generally includes a main frame, a self-loading hopper, a hopper hydraulic cylinder, a connecting arm, and a front-loading bucket located at the end of the connecting arm. The front-loading bucket is detachably connected to the connecting arm (a schematic diagram of the tracked transport vehicle after the front-loading bucket is removed from the connecting arm is shown in the figure). Figure 2 As shown), the front loading hopper is used to load and unload materials into the self-loading hopper.
[0004] Current tracked transport vehicles only have one working mode, which is to load and transfer materials through the hopper; however, with the diversification of material types and the increasing demand for work efficiency, the market is now in need of a tracked transport vehicle with multiple functions, such as a multi-functional tracked transport vehicle that can load materials through the hopper and pick up goods through the forks.
[0005] In existing technologies, if it is desired to use a hopper to transfer loose materials and a forklift to transfer large, whole materials, separate tracked transport vehicles operating independently of the hopper and forklifts operating independently of the forks are required. This approach results in high construction costs and reduced work efficiency. Therefore, improving the versatility of tracked transport vehicles—that is, enabling a single tracked transport vehicle to switch between hopper loading and forklift loading—to reduce construction costs and improve work efficiency, is a pressing technical problem that needs to be solved.

[0041] In the following description, embodiments of the present invention will be illustrated with reference to the accompanying drawings. In the drawings, the same reference numerals denote the same or similar parts.
[0042] Figure 7 This is a schematic diagram of the fork structure for a tracked transport vehicle according to an embodiment of this application, as shown below. Figure 7 As shown, the fork structure may specifically include a fork support and a fork body.
[0043] The fork support is used to connect to the connecting arms 130 on both sides of the hopper 110 of the tracked transport vehicle 100. The fork support includes a support body 210 and a connecting lug 212. The connecting lug 212 is fixedly connected to the support body 210 and is located on the side of the support body 210 closer to the hopper 110. The fork body includes two parallel fork arms 221. The two fork arms 221 are located on the side of the fork support away from the hopper 110, and one end of the two fork arms 221 is connected to the fork support.
[0044] like Figure 3 and Figure 5 As shown, the side of the support body 210 closest to the hopper 110 can be understood as the right side of the support body 210, and the side of the fork support away from the hopper 110 can be understood as the left side of the fork support. At this time, the two fork arms 221 have a gap in the width direction of the tracked transport vehicle 100, which can be understood as... Figure 4 and Figure 6 The direction perpendicular to the plane of the paper. In the above embodiment, the two fork arms 221 have the same structure and dimensions, and the right ends of both fork arms 221 are connected to the fork support. Specifically, the two fork arms 221 are symmetrical about the front and rear with respect to the center plane of the tracked transport vehicle 100.
[0045] The fork support bracket and connecting arm 130 in this application are detachably connected, thereby realizing a detachable connection between the fork structure and the tracked transport vehicle 100. That is, when the fork structure and the connecting arm 130 of the tracked transport vehicle 100 are connected, the tracked transport vehicle 100 can pick up goods based on the forks, and its working mode is equivalent to that of a forklift; while when the fork structure and the connecting arm 130 of the tracked transport vehicle 100 are separated, the tracked transport vehicle 100 can only load goods through the hopper 110.
[0046] Figure 1 The diagram shows the structure of a prior art tracked transporter 100, which can only load goods through the hopper 110. To fix the fork structure of this application to the connecting arm 130, the front bucket 120 needs to be detached from the connecting arm 130 first. Then, the connecting lugs of the fork bracket are fixed to the end of the connecting arm 130 using screws or bolts, thus achieving the connection between the fork structure and the tracked transporter 100. A schematic diagram of the fork structure fixed to the tracked transporter 100 is shown below. Figures 3 to 6 As shown; in this state, the tracked transporter 100 can pick up goods using its forks.
[0047] For example, the connecting lug 212 on the fork support is fixedly connected to the left end of the connecting arm 130, while the right end of the connecting arm 130 is hinged to the bottom of the hopper 110 and the end of the cylinder rod of the hopper hydraulic cylinder. Therefore, as the cylinder rod of the hopper hydraulic cylinder extends and retracts, the fork structure can rise or fall with the rotation of the connecting arm 130. Figure 5 and Figure 6 When the cylinder rod of the hydraulic cylinder retracts to its original position, the fork structure descends to its lowest position; for example... Figure 3 and Figure 4 When the cylinder rod of the hydraulic cylinder is fully extended, the fork structure rises to its highest position. In this embodiment, the fork structure is raised and lowered by the hopper hydraulic cylinder, and the hopper hydraulic cylinder used to drive the connecting arm can be further driven by the control handle of the tracked transport vehicle 100.
[0048] In one embodiment, there are two connecting ear plates 212, which are arranged parallel to each other and spaced apart. Each connecting ear plate 212 is detachably connected to the corresponding connecting arm 130. Figure 8As shown, two connecting lugs are located at both ends of the support body 210, and the two connecting lugs 212 have a symmetrical front-to-back structure. Specifically, each connecting lug is provided with multiple bolt fixing holes, and the bolt fixing holes on the connecting lugs correspond to the bolt fixing holes on the ends of the connecting arms 130. In this embodiment, the bolt fixing holes on the connecting arms 130 are specifically located at the ends of the connecting arms 130, and each connecting lug 212 is detachably connected to the end of the corresponding connecting arm 130 away from the hopper hydraulic cylinder 140. It is understood that setting the connecting lugs 212 to be detachably connected to the ends of the connecting arms 130 is only one example. In some other embodiments, the bolt fixing holes on the connecting arms 130 may also be located in the middle of the connecting arms 130, in which case each connecting lug 212 is detachably connected to the middle of the connecting arms 130.
[0049] In some embodiments, the spacing between the two fork arms 221 can be adjusted based on the width of the cargo; in this embodiment, a guide assembly is provided between the fork arms 221 and the fork support, the guide assembly allowing the fork arms 221 to move along the width direction of the fork support. The width direction of the fork support can be understood as... Figure 4 and Figure 6 The direction perpendicular to the paper surface; in this implementation, the sliding fork arm 221 can adjust the spacing between the fork arms 221, thereby adapting to picking up goods of different sizes.
[0050] For example, the guiding component includes a guide groove 222 and a guide rail 211. One of the guide groove 222 and the guide rail 211 is disposed at the top of the end of the fork arm 221 for connection with the fork support, and the other of the guide groove 222 and the guide rail 211 is disposed at the top of the support body 210. In this embodiment, the fork arm 221 and the fork support are guided by a guide rail and guide groove structure. It is understood that the movement of the fork arm 221 relative to the fork support based on the guide rail and guide groove structure is only one example. In some other embodiments, the guiding component may be other structures besides the guide rail and guide groove structure, such as a pulley and slide rail structure.
[0051] For example, the guide groove 222 is located on the fork arm 221, the guide rail 211 is located on the fork body, and the guide rail 211 is located on top of the connecting lug 212. Figure 8 As shown, when the guide rail 211 is located on the fork body, the guide rail 211 is specifically located on the top of the connecting lug plate; in the width direction of the tracked transport vehicle, the size of the guide rail 211 can be the same as the size of the fork support. In addition, besides setting the guide rail 211 on the fork support and setting the guide groove 222 on the fork arm 221, the guide rail 211 can also be set on the fork arm 221, and the guide groove 222 can be set on the fork support.
[0052] Figure 8 This is a schematic diagram of the fork support structure according to an embodiment of this application, as shown below. Figure 8 As shown, the support body 210 can specifically be a rectangular plate. The guide rail 211 and the connecting ear plate 212 are located on the same side of the rectangular plate, and the top of the guide rail 211 is flush with the top of the rectangular plate. In this embodiment, both the connecting ear plate 212 and the guide rail 211 are located on the right side of the rectangular plate. At this time, the two connecting ear plates 212 are located at both ends of the rectangular plate, and both connecting ear plates 212 are located below the guide rail 211. Further, the guide rail 211 includes a top plate 211-1, a bottom plate 211-2, and two right-angled trapezoidal side plates 211-3. The top plate 211-1 and the bottom plate 211-2 are parallel and spaced apart. The two right-angled trapezoidal side plates 211-3 are located at both ends of the top plate 211-1, and both ends of the top plate 211-1 and the bottom plate 211-2 are connected to the two right-angled trapezoidal side plates 211-3 respectively. Figure 8 As shown, in the width direction of the tracked transport vehicle 100, the bottom plate 211-2 and top plate 211-1 of the guide rail 211 have the same dimensions, and the dimensions of the bottom plate 211-2 and top plate 211-1 are also the same as the width direction dimensions of the support body 210; the top and bottom ends of the right-angled trapezoidal side plate 211-3 are connected to the ends of the top plate 211-1 and the bottom plate 211-2 respectively, and the right-angled side of the right-angled trapezoidal side plate 211-3 is connected to the support body 210.
[0053] In some embodiments of this utility model, the top plate 211-1 has a vertically bent edge 211-4 extending toward the bottom plate 211-2 on the side away from the rectangular plate. For example... Figure 8 As shown, the right side of the top plate 211-1 is provided with a vertically bent plate that bends downwards. This vertically bent plate can improve the support strength of the guide rail 211 and can better guide the guide when it cooperates with the guide groove 222.
[0054] Furthermore, the bottom end of the fork arm 221 is flush with the bottom end of the rectangular plate, the guide groove 222 is inverted U-shaped, and one side wall of the inverted U-shaped guide groove 222 is in contact with the rectangular plate, while the other side wall of the inverted U-shaped guide groove 222 is in contact with the vertical bending edge 211-4. For example... Figure 9 As shown, the inverted U-shaped guide groove is located at the right end of the fork arm 221. The inverted U-shaped guide groove cooperates with the guide rail 211 on the fork support, so that the fork arm 221 can move along the fork support to adjust the distance between the two fork arms 221.
[0055] Additionally, the fork structure may include a fork arm positioning component 223, which is used to position the forks relative to the fork support. After adjusting the distance between the two fork arms 221 to a suitable size, the fork arms 221 can be further fixed by the fork arm positioning component 223 to prevent the fork arms 221 from sliding relative to the support body 210 during operation. For example, the fork arm positioning component 223 may specifically be a bolt; that is, the right side wall of the U-shaped guide groove 222 of the fork arm 221 is provided with bolt mounting holes, thus fixing the fork arm 221 to the fork support is achieved by using bolts.
[0056] Accordingly, the present invention also provides a tracked transport vehicle, the tracked transport vehicle including the fork structure for tracked transport vehicles as described in any of the above embodiments.
[0057] The fork structure and tracked transport vehicle disclosed in the above embodiments of the present invention have a simple overall structure, are easy to manufacture and install; since they can realize the loading and transportation of goods based on the hopper, and can also realize the picking and transportation of goods based on the forks, the practicality and versatility of the vehicle are improved; compared with other tracked transport vehicles that require two independent tracked transport vehicles to complete the loading of materials in the hopper and the picking of goods with the forks, this tracked transport vehicle reduces the operating cost and improves the working efficiency.
[0058] In this invention, features described and / or illustrated for one embodiment may be used in the same or similar manner in one or more other embodiments, and / or combined with or in place of features of other embodiments.
[0059] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. For those skilled in the art, various modifications and variations can be made to the embodiments of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
