[0002] A hoisting device for aerial transport using a truck crane is a specially designed device that uses a truck crane as a carrier and, through a specific mechanical structure and control system, enables the transport of objects in the air. This device is mainly designed to compensate for the shortcomings of traditional truck cranes in aerial transport tasks and to expand the functional range of truck cranes.

[0003] In existing technologies, the common hoisting method is a combination of hooks and ropes, which can shorten hoisting time and improve work efficiency. At the same time, hooks and ropes are relatively simple to maintain and have high durability, which can reduce maintenance costs during long-term use.

[0004] However, in actual use, when the above-mentioned device is used to tie the workpiece together with a combination of hooks and ropes for hoisting, the workpiece is easily damaged due to the large squeezing force exerted by the ropes on it. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a hoisting device for aerial transport by a truck crane, which can effectively solve the problem that the existing technology uses a combination of hooks and ropes to tie the workpiece before hoisting, and the large squeezing force of the rope on the workpiece can easily lead to damage to the workpiece.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides a hoisting device for aerial transport by a truck crane, including a support plate. A drive motor is provided at the bottom of the support plate, and a fixing mechanism is provided at the output end of the drive motor. The fixing mechanism includes a drive gear fixedly mounted on the output shaft of the drive motor. The drive gear meshes with a first driven rack and a second driven rack. A second fixing plate is fixedly mounted at the lower end of the first driven rack, and a first fixing plate is fixedly mounted at the lower end of the second driven rack. The first fixing plate and the second fixing plate are engaged. An elastic mechanism is fixedly connected to the first fixing plate and the second fixing plate. A connecting member is provided at the top of the support plate.

[0008] Furthermore, the support plate has a first sliding groove and a second sliding groove inside. The first sliding groove is slidably connected to the first driven rack, and the second sliding groove is slidably connected to the second driven rack. The driving gear is rotatably installed inside the support plate.

[0009] Furthermore, the lower surface of the support plate is provided with a third sliding groove and a fourth sliding groove, the third sliding groove being slidably connected to the first fixed plate, and the fourth sliding groove being slidably connected to the second fixed plate.

[0010] Furthermore, the first fixing plate has a slot on the side near the second fixing plate, and the second fixing plate has a block on the side near the first fixing plate, the block engaging with the slot.

[0011] Furthermore, the elastic mechanism includes two sets of springs fixedly installed on the first fixed plate and the second fixed plate. The springs are fixedly installed on the support plate, and the springs are sleeved on the surface of the guide rods and slidably connected to the guide rods. One set of the guide rods is slidably connected to the first fixed plate, and the other set of the guide rods is slidably connected to the second fixed plate.

[0012] Furthermore, the lower surface of the support plate is provided with two sets of auxiliary sliding grooves, one set of which is slidably connected to a first fixing plate, and the other set of which is slidably connected to a second fixing plate.

[0015] Beneficial effects

[0016] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0017] I. This utility model drives the active gear to rotate via a drive motor, which in turn drives the first driven rack and the second driven rack to slide on the groove in the support plate. This allows the first fixed plate and the second fixed plate to approach and engage with each other precisely and stably, thereby achieving a firm clamping of the workpiece. Due to the self-locking property between the gear and the rack, the workpiece is effectively prevented from shaking or falling off during transportation, significantly improving the stability and safety of workpiece clamping.

[0018] Second, the elastic mechanism of this utility model provides a buffer effect for the first and second fixing plates, reducing the impact and vibration caused by workpiece clamping. At the same time, the shock-absorbing plates and anti-slip textures on the surfaces of the first and second fixing plates can absorb and disperse the impact force from the outside, preventing the workpiece from being damaged by vibration or impact during transportation.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] The present invention will be further described below with reference to the embodiments.

[0028] A lifting device for aerial transport by a truck crane, as shown in the attached figure. Figures 1-5The system includes a support plate 1, a drive motor 9 at its bottom, and a fixing mechanism at the output end of the drive motor 9. The fixing mechanism includes a drive gear 7 fixedly mounted on the output shaft of the drive motor 9. The drive gear 7 meshes with a first driven rack 8 and a second driven rack 10. A second fixing plate 4 is fixedly mounted at the lower end of the first driven rack 8, and a first fixing plate 3 is fixedly mounted at the lower end of the second driven rack 10. The support plate 1 has a first sliding groove 11 and a second sliding groove 12 inside. The first sliding groove 11 is slidably connected to the first driven rack 8, and the second sliding groove 12 is slidably connected to the second driven rack 10. The drive gear 7 is rotatably mounted on the support plate 1. Internally, when it is necessary to clamp and fix the workpiece, the output shaft of the drive motor 9 is controlled to rotate in the forward direction. The drive motor 9 drives the drive gear 7 to rotate through the output shaft. The drive gear 7 drives the first driven rack 8 and the second driven rack 10 to slide on the first slide groove 11 and the second slide groove 12 respectively through meshing. This causes the first fixing plate 3 and the second fixing plate 4 to move closer to each other. Due to the self-locking property between the gear and the rack, the clamping effect on the workpiece is effectively improved. Finally, the first fixing plate 3 and the second fixing plate 4 are engaged, thereby achieving the clamping and fixing of the workpiece. This effectively avoids the accident caused by the workpiece falling off due to the workpiece not being firmly fixed during transportation.

[0029] In the above technical solution, the lower surface of the support plate 1 is provided with a third sliding groove 17 and a fourth sliding groove 18. The third sliding groove 17 is slidably connected to the first fixed plate 3, and the fourth sliding groove 18 is slidably connected to the second fixed plate 4. When it is necessary to unload the workpiece, the output shaft of the drive motor 9 is controlled to rotate in the opposite direction, so that the first fixed plate 3 slides stably along the third sliding groove 17 and in the opposite direction to the second fixed plate 4. At the same time, the second fixed plate 4 slides along the fourth sliding groove 18 and in the opposite direction to the first fixed plate 3, thereby realizing the stable unloading of the workpiece.

[0030] Furthermore, the first fixing plate 3 and the second fixing plate 4 are interlocked. The first fixing plate 3 has a slot 6 on the side near the second fixing plate 4, and the second fixing plate 4 has a block 5 on the side near the first fixing plate 3. The block 5 is interlocked with the slot 6. When the first fixing plate 3 and the second fixing plate 4 approach each other, the block 5 on the first fixing plate 3 will enter the slot 6. The interlocking of the first fixing plate 3 and the second fixing plate 4 can ensure a stable connection between the two parts, so that the workpiece can be better fixed, and at the same time improve the work efficiency to a certain extent.

[0031] The first fixed plate 3 and the second fixed plate 4 are fixedly connected by an elastic mechanism. The elastic mechanism includes two sets of springs 15 fixedly installed on the first fixed plate 3 and the second fixed plate 4. The springs 15 are fixedly installed on the support plate 1. The springs 15 are sleeved on the surface of the guide rods 16, and the springs 15 and the guide rods 16 are slidably connected. One set of guide rods 16 is slidably connected to the first fixed plate 3, and the other set of guide rods 16 is slidably connected to the second fixed plate 4. Two sets of auxiliary sliding grooves 14 are opened on the lower surface of the support plate 1. One set of auxiliary sliding grooves 14 is slidably connected to the first fixed plate 3, and the other set of auxiliary sliding grooves 14 is slidably connected to the second fixed plate 4. The guide rod 16 passes through the first fixed plate 3 and the second fixed plate 4, and both ends of the guide rod 16 are fixedly installed on the support plate 1. During the clamping and fixing of the workpiece by the fixing mechanism, the first fixed plate 3 and the second fixed plate 4 slide on the auxiliary slide groove 14. The guide rod 16 is used to provide a specific movement path for the first fixed plate 3 and the second fixed plate 4 to avoid derailment, thereby increasing the stability of the device. At the same time, the spring 15 provides a buffering effect when the first fixed plate 3 and the second fixed plate 4 approach each other, reducing the impact force and vibration caused by workpiece clamping, thereby protecting the workpiece and the fixed plate from damage.

[0032] In addition, a connector 2 is provided at the top of the support plate 1, and shock-absorbing plates 19 are provided on the surfaces of the first fixed plate 3 and the second fixed plate 4. The upper surface of the shock-absorbing plate 19 is provided with anti-slip texture 21, and the surfaces of the first fixed plate 3 and the second fixed plate 4 are provided with reinforcing arc-shaped strips 20. The connector 2 is used to connect the ropes on the crane body to realize the transportation of the workpiece. During the crane transportation of the workpiece, due to the weight of the workpiece and the dynamic changes during transportation, a large vibration and impact force will be generated. The shock-absorbing plate 19 can absorb and disperse the impact force from the outside through its elastic deformation ability. The anti-slip texture 21 effectively increases the contact area and friction coefficient between the workpiece and the shock-absorbing plate 19, thereby preventing the workpiece from sliding or shifting. This not only improves the stability of transportation but also ensures the safety of the workpiece during transportation. The reinforcing arc-shaped strip 20 further protects and fixes the workpiece to prevent damage during transportation.

[0033] Working principle: When it is necessary to clamp and fix the workpiece, the drive motor 9 drives the drive gear 7 to rotate, which in turn drives the first driven rack 8 and the second driven rack 10 to slide on the first slide groove 11 and the second slide groove 12 in the support plate 1, respectively. This causes the first fixing plate 3 and the second fixing plate 4 to move closer to each other and engage, thereby clamping and fixing the workpiece. At the same time, the spring 15 and the guide rod 16 provide buffer and stable movement path for the first fixing plate 3 and the second fixing plate 4, increasing the stability of the device. During transportation, the shock absorber 19 and the anti-slip texture 21 absorb the impact force and prevent the workpiece from sliding. The reinforced arc belt 20 further protects the workpiece. When unloading, the reverse drive motor 9 separates the first fixing plate 3 and the second fixing plate 4, achieving stable unloading.

[0034] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
