Description
Technical Field
[0001] This utility model relates to the field of rail lifting equipment technology, and in particular to a novel rail lifting equipment. Background Technology
[0002] Lifting gear refers to the devices used in lifting machinery to lift heavy objects. The most commonly used lifting gear for lifting packaged items is hooks and slings. Other types include lifting rings, lifting suction cups, clamps, and forks, which are widely used in the lifting and hoisting industry. Among the commonly used lifting gear, specialized rigging such as hooks, wire ropes, and chains are essential.
[0003] Currently, most rail lifting devices on the market have an integrated structure between the bottom clamping hook and the lifting device. This integrated structure makes it difficult to disassemble the entire device. If the clamping hook is damaged during use, the entire lifting device needs to be replaced, which not only wastes resources but also increases the cost of use, resulting in poor overall practicality. Utility Model Content
[0004] This utility model addresses the shortcomings of existing technologies by providing the following technical solution:
[0005] A novel rail lifting device includes a lifting device frame, a slot opened on the top surface of the lifting device frame, and a guide seat slidably connected to the inner cavity of the slot.
[0006] The bottom of the guide seat is fixedly provided with a connecting seat, and the bottom of the connecting seat is provided with a snap-fit structure. A clamping hook is snap-fitted to the inner side of the bottom of the connecting seat, and a protrusion is fixedly provided on the side wall of the clamping hook. A hexagonal groove is provided in the middle of the top of the clamping hook. A strong spring is fixedly connected to the inner cavity of the top of the clamping hook, and a locking rod is fixedly connected to the other end of the strong spring. An auxiliary sliding plate is sleeved on the outer surface of one end of the locking rod.
[0007] Preferably, the engaging structure includes a slot, a locking hole, a guide post, and a groove. The slot is located at the bottom of the connector, and one end of the slot is connected to the locking hole. The guide post is provided in the inner cavity of the slot, and a groove is provided on the lower surface of the connector.
[0008] Preferably, a first rotating rod is rotatably connected to the top of the guide seat, and a second rotating rod is rotatably connected to the other end of the first rotating rod. A hanging seat is connected to the end of the second rotating rod away from the first rotating rod, and a third rotating rod is provided on one side of the bottom of the hanging seat. A fourth rotating rod is connected to the bottom of the third rotating rod.
[0009] Preferably, the slots are equidistantly distributed along the bottom of the connector, and the slots and the connector form an integrated structure.
[0010] Preferably, the outer diameter of the guide post is adapted to the inner diameter of the hexagonal groove, and the hexagonal groove and the clamping hook form an integrated structure.
[0011] Preferably, the clamping hooks are equidistantly distributed along the bottom of the connecting seat, and are obliquely symmetrically distributed along the lifting frame, with the orientations of the symmetrically arranged clamping hooks staggered.
[0012] Preferably, the locking rod is slidably connected to the clamping hook by a strong spring, and the outer diameter of the locking rod is adapted to the inner diameter of the lock hole.
[0013] As an improvement to the above technical solution, the connection seat, guide column, locking rod and strong spring are designed to facilitate quick assembly and disassembly of the clamping hook during subsequent use, so that the entire lifting device will not need to be replaced when a single clamping hook is damaged.
[0014] The beneficial effects of this utility model are:
[0015] 1. This utility model, through its connecting seat, clamping hook, protrusion, and locking rod, allows for quick assembly and disassembly of the clamping hook during subsequent use. When a single clamping hook is damaged, only that hook needs to be replaced, eliminating the need to replace the entire clamping hook. Furthermore, the modular structure makes the assembly and disassembly of the clamping hook more convenient and quick, resulting in higher overall practicality.
[0016] 2. The present invention, through the setting of protrusions, guide posts and hexagonal grooves, can provide a certain guiding effect when installing the clamping hook, so as to prevent the clamping hook from shifting during installation and affecting the stability of the subsequent installation effect. In addition, the setting of protrusions and guide posts can also serve the purpose of limiting, ensuring the stability of the clamping hook installation. Attached Figure Description

[0023] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.
[0024] Reference Figure 1-5 A novel rail lifting device includes a lifting device frame 1, a slot 2 opened on the top surface of the lifting device frame 1, and a guide seat 3 slidably connected to the inner cavity of the slot 2.
[0025] A connecting seat 4 is fixedly provided at the bottom of the guide seat 3, and a locking structure is provided at the bottom of the connecting seat 4. The locking structure includes a slot 5, a locking hole 6, a guide post 7 and a groove 8. The slot 5 is provided at the bottom of the connecting seat 4, and one end of the slot 5 is connected to the locking hole 6. The inner cavity of the slot 5 is provided with the guide post 7. The lower surface of the connecting seat 4 is provided with a groove 8. A clamping hook 9 is engaged and connected to the inner side of the bottom of the connecting seat 4, and a protrusion 10 is fixedly provided on the side wall of the clamping hook 9. A hexagonal groove 11 is provided at the middle of the top of the clamping hook 9. A strong spring 12 is fixedly connected to the inner cavity of the top of the clamping hook 9, and a locking rod 13 is fixedly connected to the other end of the strong spring 12. An auxiliary sliding plate 14 is sleeved on the outer surface of one end of the locking rod 13.
[0026] In this embodiment, when it is necessary to disassemble and replace the clamping hook 9, the locking rod 13 is squeezed. At this time, the locking rod 13 will move inward towards the clamping hook 9 under the action of external force. Then, as the locking rod 13 retracts, it will drive the auxiliary slide plate 14 to move synchronously, thereby improving the stability of the locking rod 13 during the lateral retraction process. As the locking rod 13 retracts, the strong spring 12 will also deform and generate a reverse force. When the locking rod 13 is fully retracted to the inside of the clamping hook 9, one end of the locking rod 13 will separate from the lock hole 6. Then, the clamping hook 9 can be disengaged from the bottom of the connecting seat 4 by longitudinally moving it, which facilitates the subsequent disassembly of the clamping hook 9. Conversely, to install the clamping hook 9, the locking rod 13 is squeezed in advance to retract to the inside of the top of the clamping hook 9. The clamping hook 9 is pushed longitudinally to engage with the slot 5 at the bottom of the connecting seat 4, thus achieving initial connection between the two. At the same time, as the clamping hook 9 engages with the connecting seat 4, the symmetrically arranged protrusions 10 on its side wall are engaged with the inside of the groove 8, thus providing guidance for the engagement. Subsequently, when the clamping hook 9 is fully engaged with the inside of the slot 5, the hexagonal groove 11 engages with the guide post 7, further providing guidance for the engagement of the clamping hook 9. Meanwhile, the locking rod 13 moves to one side of the lock hole 6, and under the reverse force generated by the deformation of the strong spring 12, one end of the locking rod 13 can be re-input into the inside of the lock hole 6, thereby achieving the positioning of the clamping hook 9 and ensuring its stability in subsequent use.
[0027] In this utility model, the top end of the guide seat 3 is rotatably connected to a first rotating rod 15, and the other end of the first rotating rod 15 is rotatably connected to a second rotating rod 16. The end of the second rotating rod 16 away from the first rotating rod 15 is connected to a hanging seat 17, and a third rotating rod 18 is provided on one side of the bottom of the hanging seat 17. The bottom of the third rotating rod 18 is connected to a fourth rotating rod 19.
[0028] In this embodiment, under the action of external force, the lifting seat 17 will move longitudinally. At this time, the longitudinal movement of the lifting seat 17 will drive the second rotating rod 16 and the third rotating rod 18, which are rotatably connected to one side of the bearing seat, to rotate. Since the other ends of the second rotating rod 16 and the third rotating rod 18 are rotatably connected to the first rotating rod 15 and the fourth rotating rod 19, respectively, the first rotating rod 15 and the fourth rotating rod 19 will also rotate as the second rotating rod 16 and the third rotating rod 18 move. This will push the guide seat 3, which is fixedly connected to its bottom, so that the guide seat 3 can slide inside the slot 2, realizing the opposite movement of the connecting seats 4. It is worth noting that since there are four connecting seats 4, and the four connecting seats 4 are arranged in pairs, and each pair of connecting seats 4 moves in opposite directions, the movement of the connecting seats 4 will drive the clamping hooks 9 at their bottom to move in opposite directions as well, so that the rail structure can be clamped and lifted.
[0029] In this utility model, the slots 5 are evenly distributed along the bottom of the connecting seat 4, and the slots 5 and the connecting seat 4 form an integrated structure.
[0030] In this embodiment, the size of the slot 5 is adapted to the size of the clamping hook 9, so when one end of the clamping hook 9 is inserted into the inside of the slot 5, it is convenient to realize the initial connection between the clamping hook 9 and the connecting seat 4.
[0031] In this utility model, the outer diameter of the guide post 7 is adapted to the inner diameter of the hexagonal groove 11, and the hexagonal groove 11 and the clamping hook 9 form an integrated structure.
[0032] In this embodiment, since the size of the guide post 7 is compatible with the size of the hexagonal slot 11, the guide post 7 can be used to guide the device when the two are engaged.
[0033] In this utility model, the clamping hooks 9 are equidistantly distributed along the bottom of the connecting seat 4, and the clamping hooks 9 are obliquely symmetrically distributed along the lifting frame 1, and the orientations of the symmetrically arranged clamping hooks 9 are staggered.
[0034] In this embodiment, as the connecting seat 4 moves, the clamping hook 9 detachably connected to its bottom also moves laterally. Since the clamping hooks 9 equidistantly distributed at the bottom of the connecting seats 4 on both sides are staggered and the connecting seats 4 on both sides move towards each other, the clamping hooks 9 can move towards each other as the connecting seats 4 move towards each other, which facilitates the subsequent clamping of the rail.
[0035] In this utility model, the locking rod 13 is slidably connected to the clamping hook 9 by a strong spring 12, and the outer diameter of the locking rod 13 is adapted to the inner diameter of the lock hole 6.
[0036] In this embodiment, the reverse force generated by the deformation of the strong spring 12 will push the locking rod 13, thereby inputting one end of the locking rod 13 into the inside of the lock hole 6, which facilitates the subsequent positioning of the clamping hook 9.
[0037] The usage and working principle of this new type of rail lifting device are as follows: During use, the lifting base 17 moves longitudinally under the action of external force. This longitudinal movement of the lifting base 17 causes the second rotating rod 16 and the third rotating rod 18, which are rotatably connected to one side of the lifting base via bearing seats, to rotate accordingly. Since the other ends of the second rotating rod 16 and the third rotating rod 18 are rotatably connected to the first rotating rod 15 and the fourth rotating rod 19, respectively, the movement of the second rotating rod 16 and the third rotating rod 18 causes the first rotating rod 15 and the fourth rotating rod 19 to rotate as well. This, in turn, pushes the guide seat 3 fixedly connected to its bottom, thereby guiding the guide... The connecting seat 3 slides inside the slot 2, enabling the connecting seats 4 to move in opposite directions. Since there are four connecting seats 4, arranged in pairs, and each pair moves in opposite directions, the movement of the connecting seats 4 will cause the clamping hooks 9 at their bottoms to also move in opposite directions, thus allowing for the clamping and lifting of the rail structure. When it is necessary to disassemble or replace the clamping hooks 9, the locking rod 13 is pressed. Under the action of external force, the locking rod 13 will move inward towards the clamping hooks 9. Then, as the locking rod 13 retracts, it will cause the auxiliary sliding plate 14 to move synchronously, thereby raising the locking rod 13. The stability during the lateral retraction process is ensured, and the strong spring 12 also deforms and generates a reverse force as the locking rod 13 retracts. When the locking rod 13 is fully retracted to the inside of the clamping hook 9, one end of the locking rod 13 will separate from the lock hole 6. Then, the clamping hook 9 can be moved longitudinally to disengage it from the bottom of the connecting seat 4, facilitating subsequent disassembly of the clamping hook 9. Conversely, to install the clamping hook 9, the locking rod 13 is pre-pressed to retract to the inside of the top of the clamping hook 9. Then, the clamping hook 9 is pushed longitudinally to engage with the slot 5 at the bottom of the connecting seat 4, achieving initial connection between the two. At the same time, as the clamping hook 13 retracts to the inside of the lock hole 6, the locking rod 13 will be fully retracted to the inside of the lock hole 6. Then, the clamping hook 9 will be pushed longitudinally to engage with the slot 5 at the bottom of the connecting seat 4, achieving initial connection between the two. When the hook 9 engages with the connecting seat 4, the symmetrically arranged protrusions 10 on its side wall are engaged inside the groove 8, thus providing guidance for the engagement. Subsequently, when the hook 9 is fully engaged inside the slot 5, the hexagonal groove 11 engages with the guide post 7, further guiding the engagement of the hook 9. At the same time, the locking rod 13 moves to one side of the lock hole 6, and under the reverse force generated by the deformation of the strong spring 12, one end of the locking rod 13 can be re-input into the inside of the lock hole 6, thereby achieving the positioning of the hook 9 and ensuring its stability in subsequent use.
[0038] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
