Description

Technical Field

[0001] This invention relates to the field of pile driver technology, and in particular to a composite guide rail structure for a photovoltaic pile driver. Background Technology

[0002] A photovoltaic (PV) piling machine is a type of piling machine that plays a crucial role in the construction of photovoltaic power plants. Its main function is to fix photovoltaic panels to the ground through piling, achieving a stable, safe, and secure result. During piling, the PV piling machine needs to be able to lift the piling structure and control its lifting height. Existing PV piling machines generally use a chain mounted on a single guide rail to drive the piling structure's lifting and lowering. However, this method requires a long guide rail, occupies a large space, and is inconvenient for transportation. Summary of the Invention

[0003] This invention provides a composite guide rail structure for photovoltaic pile drivers, which at least solves some of the problems existing in the prior art.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] A composite guide rail structure for a photovoltaic pile driver includes an outer slide rail, a middle slide rail, and an inner slide rail. The middle slide rail is slidably installed inside the outer slide rail, and the inner slide rail is slidably installed inside the middle slide rail. A follower frame is slidably installed on the inner slide rail, and a transmission structure is provided on the middle slide rail. When the inner slide rail moves on the middle slide rail, the transmission structure can drive the follower frame to move on the inner slide rail.

[0006] Preferably, a first hydraulic cylinder is hinged to the outer slide rail, and the end of the first hydraulic cylinder away from the outer slide rail is hinged to the middle slide rail. A second hydraulic cylinder is hinged to the middle slide rail, and the end of the second hydraulic cylinder away from the middle slide rail is hinged to the inner slide rail.

[0007] Preferably, the middle slide includes a connecting seat and two U-shaped rails. The connecting seat includes a connecting plate and a U-shaped sleeve fixed on the connecting plate. The U-shaped sleeve is fixed on the top outer wall of the two rails. A mounting seat is fixed on one side of the connecting plate between the two rails. The cylinder body of the second hydraulic cylinder is hinged to the mounting seat at one end near the piston rod.

[0008] Preferably, the piston rod of the second hydraulic cylinder is hinged to the first support fixed to the inner side of the top of the inner slide.

[0009] Preferably, the transmission structure includes a first transmission bar and a second transmission bar. One end of the first transmission bar is connected to the follower frame, and the other end of the first transmission bar passes around the first steering wheel on the first support and is connected to the connecting seat. One end of the second transmission bar is connected to the follower frame, and the other end of the second transmission bar passes around the second steering wheel rotatably mounted at the bottom of the inner slide and is connected to the mounting seat.

[0010] Preferably, the mounting base includes a back plate bolted to the connecting plate and two limiting plates fixed on the back plate. The limiting plates are provided with hinge shaft grooves, and a detachable limiting block is provided on one side of the hinge shaft groove.

[0011] Preferably, a U-shaped locking block is fixed on the back plate to limit the range of motion of the piston rod of the second hydraulic cylinder.

[0012] Preferably, guide blocks are fixed on both sides of the follower frame, the guide blocks can slide inside the inner slide, and a liner is fixed on the guide blocks.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] 1. By setting an outer slide rail, an inner slide rail, and a middle slide rail, and setting a transmission structure on the middle slide rail, when the inner slide rail is driven to move on the middle slide rail, the follower frame can move on the inner slide rail, thus facilitating the adjustment of the height position of the follower frame; by designing the middle slide rail as a structure with two rails fixedly connected, the second hydraulic cylinder can be set between the two rails, so that the second hydraulic cylinder is located inside the middle slide rail, making the structure compact and occupying less external space;

[0015] 2. The cylinder body of the second hydraulic cylinder is hinged to the mounting base at one end near the piston rod. This achieves the hinge connection between the cylinder body and piston rod of the second hydraulic cylinder and the middle slide and the inner slide, respectively, while minimizing the distance between the two hinge shafts. This greatly reduces the vibration of the second hydraulic cylinder during pile driving and extends its service life. Attached Figure Description

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Example 1

[0027] like Figures 1 to 7 As shown in Embodiment 1 of the present invention, a composite guide rail structure for a photovoltaic pile driver includes an outer slide rail 1, a middle slide rail 2, and an inner slide rail 3. The outer slide rail 1 is hinged to a frame 23, and a tracked chassis 22 is provided at the bottom of the frame 23. The outer slide rail 1 can rotate from a horizontal state to a vertical state under the action of a hydraulic cylinder. The middle slide rail 2 is slidably installed inside the outer slide rail 1, and the inner slide rail 3 is slidably installed inside the middle slide rail 2. Therefore, when the outer slide rail 1 rotates, it can rotate the middle slide rail 2 and the inner slide rail 3 together. A follower frame 4 is slidably installed on the inner slide rail 3, and the follower frame 4 can move on the inner slide rail 3. A pile driving structure 24 is installed on the follower frame 4. By driving the middle slide rail 2 to move along the outer slide rail 1, the inner slide rail 3 is driven to move on the middle slide rail 2, thereby realizing the lifting and lowering of the inner slide rail 3. The middle slide rail 2 is also equipped with a transmission structure. The function of the transmission structure is to realize the linkage between the follower frame 4 and the inner slide rail 3. When the inner slide rail 3 moves on the middle slide rail 2, the transmission structure can drive the follower frame 4 to move on the inner slide rail 3, adjust the height of the follower frame 4, and thus control the lifting and lowering of the piling structure 24.

[0028] First, to drive the middle slide rail 2 to move on the outer slide rail 1, the present invention has a hinged seat fixed on the outer slide rail 1, and a first hydraulic cylinder 5 is hinged to the hinged seat. The end of the first hydraulic cylinder 5 away from the hinged seat is hinged to the middle slide rail 2, and the axis of the first hydraulic cylinder 5 is parallel to the direction of movement of the middle slide rail 2 on the outer slide rail 1. This allows the first hydraulic cylinder 5 to be relatively close to the middle slide rail 2 and the outer slide rail 1, saving space. To drive the inner slide rail 3 to move on the middle slide rail 2, the present invention has a second hydraulic cylinder 6 hinged to the inner side of the middle slide rail 2, and the end of the second hydraulic cylinder 6 away from the middle slide rail 2 is hinged to the inner slide rail 3. Figure 2 As shown, the second hydraulic cylinder 6 is located inside the middle slide rail 2, which saves space occupied by the second hydraulic cylinder 6 and makes the structure of the entire composite guide rail more compact.

[0029] In this invention, the outer slide rail 1, the middle slide rail 2, and the inner slide rail 3 have similar structures, each including two U-shaped tracks 7. The track 7 of the outer slide rail 1 is fitted outside the track 7 of the middle slide rail 2, and the track 7 of the middle slide rail 2 is fitted outside the inner slide rail 3. The two tracks 7 of the outer slide rail 1 are fixedly connected to each other by connecting plates, while the tops of the two tracks 7 of the middle slide rail 2 are fixed to connecting seats 8. Figure 7 and Figure 8 As shown, the connecting seat 8 includes a connecting plate 81 and a U-shaped sleeve 82. The U-shaped sleeve 82 is fixed to the connecting plate 81, and the top outer walls of the two rails 7 are welded to the U-shaped sleeve 82. A mounting seat 9 is fixed to one side of the connecting plate 81 between the two rails 7, and the end of the cylinder body of the second hydraulic cylinder 6 near the piston rod 10 is hinged to the mounting seat 9. Figure 2 As shown, the piston rod 10 of the second hydraulic cylinder 6 is hinged to the first support 11 fixed to the inner side of the top of the inner slide rail 3. The maximum distance between the hinge axis on the cylinder body of the second hydraulic cylinder 6 and the hinge axis on the piston rod 10 is approximately the stroke length of the piston rod 10. Compared to the scheme where the bottom of the cylinder body of the second hydraulic cylinder 6 is hinged to the middle slide rail 2, the shorter distance between the two sets of hinge axes significantly reduces the vibration amplitude of the second hydraulic cylinder 6 when the piling structure 24 is working, greatly improving the service life of the second hydraulic cylinder 6 and reducing the occurrence of failures.

[0030] like Figure 6As shown, to facilitate the installation and disassembly of the second hydraulic cylinder 6, the mounting base 9 designed in this invention includes a back plate 15 bolted to the connecting plate 81 and two limiting plates 16 welded to the back plate 15. Each limiting plate 16 has a hinge shaft groove 17, allowing the hinge shaft on the cylinder body of the second hydraulic cylinder 6 to be inserted into the groove from one side. Then, a limiting block 18 is bolted to the limiting plate 16 to block the hinge shaft and prevent it from detaching from the hinge shaft groove 17. To further enhance safety, a U-shaped locking block 19 is welded to the back plate 15. The piston rod 10 of the second hydraulic cylinder 6 can pass through the middle of the U-shaped locking block 19, which restricts the horizontal movement of the second hydraulic cylinder 6 and prevents it from detaching from the mounting base 9.

[0031] With the above configuration, when the first hydraulic cylinder 5 is working, it can drive the middle slide rail 2 to extend out of the outer slide rail 1, and when the second hydraulic cylinder 6 is working, it can drive the inner slide rail 3 to extend out of the middle slide rail 2. In order to allow the follower frame 4 to move in the inner slide rail 3, thereby controlling the height of the piling structure 24. The transmission structure designed in this invention includes a first transmission bar and a second transmission bar. One end of the first transmission bar is hinged to the top of the follower frame 4, and the other end of the first transmission bar passes over the first steering wheel 12 on the first support 11 and is hinged to the connecting seat 8. One end of the second transmission bar is hinged to the bottom of the follower frame 4, and the other end of the second transmission bar passes over the second steering wheel 14, which is rotatably mounted on the second support 13 at the bottom of the inner slide rail 3, and is hinged to the mounting seat 9. Thus, when the inner slide rail 3 extends from the middle slide rail 2, the distance between the first steering wheel 12 and the connecting seat 8 increases, thereby driving the first transmission bar on the inner slide rail 3 to move upward, pulling the follower frame 4 upward. Conversely, when the inner slide rail 3 retracts into the middle slide rail 2, the distance between the second steering wheel 14 and the mounting seat 9 increases, thereby driving the second transmission bar on the inner slide rail 3 to move downward, pulling the follower frame 4 downward. Therefore, the extension and retraction of the second hydraulic cylinder 6 can drive the follower frame 4 to rise and fall. The distance the follower frame 4 moves is twice the extension and retraction distance of the second hydraulic cylinder 6.

[0032] The first and second transmission bars can be ropes or chains, and the first steering wheel 12 and the second steering wheel 14 can be pulleys or sprockets, depending on the type of the first and second transmission bars.

[0033] In operation, activating the first hydraulic cylinder 5 raises the middle slide rail 2, the inner slide rail 3, and the follower frame 4 together. Activating the second hydraulic cylinder 6 causes the inner slide rail 3 to extend from the middle slide rail 2, increasing the distance between the first steering wheel 12 and the connecting seat 8. This allows the first transmission bar to pull the follower frame 4 upwards along the inner slide rail 3. Conversely, when the inner slide rail 3 retracts into the middle slide rail 2, the follower frame 4 descends along the inner slide rail 3, thus controlling the lifting and lowering of the follower frame 4.

[0034] Example 2

[0035] Based on Example 1, since the cross-sections of the two tracks 7 of the inner slide 3 are U-shaped, such as Figure 5 As shown, the present invention has guide blocks 20 fixed on both sides of the follower frame 4, and the guide blocks 20 can slide inside the track 7 of the inner slide 3. In order to reduce the frictional loss between the guide blocks 20 and the inner slide 3, wear-resistant liner plates 21 are fixed on the guide blocks 20.

[0036] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit and essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0037] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
