Technical Field
[0001] This utility model relates to the field of arched greenhouse lifting technology, specifically a crane for rapid assembly of arched greenhouses. Background Technology
[0002] Cranes for rapid assembly of arched greenhouses typically refer to specially designed or modified lifting equipment used for the efficient and rapid installation of arched greenhouse structures. They are easy to move and operate, enabling construction workers to install the greenhouse's arched supports, covering materials, and other components in a short time.
[0003] In existing technologies, the components are relatively large during the installation of arched greenhouses, making it inconvenient to move the entire device during lifting and hoisting, which can easily affect subsequent adjustments.
[0004] To overcome the above shortcomings, a prior art Chinese patent (publication number CN117842857B) discloses a prefabricated arched greenhouse installation lifting machinery for hoisting and laying the film of an arched greenhouse. It includes a support frame, a winch unit, a traction cableway, a trolley, and a sliding cableway, as well as a laying assembly and a connector. The connector is located below the trolley and has a first hydraulic cylinder between them. The laying assembly includes an unwinding motor and an inner support rod. The unwinding motor is fixed to the bottom of the connector, and the inner support rod is fixed to the output end of the unwinding motor. The outer wall of the inner support rod has multiple top rods evenly arranged circumferentially. One end of each top rod is hinged to the inner support rod, and a torsion spring is provided between them. The multiple top rods form a conical structure, and the large end of the conical structure is used to extend into the film roll to support it. The film is moved along the arched greenhouse by the trolley moving on the sliding cableway, and the unwinding of the film is achieved through the laying assembly.
[0005] Although the existing technology can overcome the shortcomings mentioned above, there are still other problems in its operation. For example, when the crane lifts a heavy arched greenhouse frame, the arched greenhouse frame is usually tubular. When the tubular arched greenhouse frame is lifted by the crane, it is more cumbersome to assemble the arched greenhouse frame on the lifting device. At the same time, the arched greenhouse frame is prone to swaying and shifting after assembly. Utility Model Content
[0006] The purpose of this utility model is to provide a crane for rapid assembly of arched greenhouses, in order to solve the problems mentioned in the background art, where the arched greenhouse frame is usually tubular, and the assembly of the arched greenhouse frame on the lifting device is cumbersome when the crane is lifting the heavy arched greenhouse frame. At the same time, the arched greenhouse frame is prone to swaying and shifting after assembly.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a crane for rapid assembly of arched greenhouses, comprising a vehicle body and a lifting platform mounted on the upper end of the vehicle body, wherein an operation compartment is provided at the upper end of the lifting platform, and a telescopic arm is provided on the outer side of the operation compartment; a connecting end is installed at the output end of the telescopic arm, and a first hydraulic telescopic rod is provided at the lower end of the connecting end, wherein a lifting end is provided at the lower output end of the first hydraulic telescopic rod, and a hoist is connected to the lower end of the lifting end; a rapid assembly mechanism is provided at the lower end of the hoist, and the arched greenhouse frame is rapidly assembled through the rapid assembly mechanism.
[0008] Furthermore, the lifting platform is rotatably connected to the control cabin, and the control cabin is equipped with control components.
[0009] Furthermore, the quick assembly mechanism is provided with a shrink chamber, and the end of the shrink chamber is fixedly installed on the outside of the lifting hook, and the lower end of the lifting hook is arc-shaped.
[0010] Furthermore, an inclined locking block is installed through the interior of the shrink chamber, and a lifting hook is installed through the middle of the inclined locking block. A locking spring is provided between the inclined locking block and the shrink chamber, and both the upper and lower sides of the inclined locking block are inclined.
[0011] Furthermore, a pressure plate is installed through the bottom of the lifting hook, and an adjusting positioning plate is rotatably installed inside the lifting hook. The adjusting positioning plates are staggered. The inner side of the adjusting positioning plate is connected to the pressure plate by a traction rope. A torsion spring is sleeved on the surface of the adjusting positioning plate, and the outer side of the torsion spring is fixedly installed on the outer side of the lifting hook.
[0012] Furthermore, the surface of the lifting platform is provided with an auxiliary support mechanism, and the auxiliary support mechanism is provided with a fixed horizontal plate. The fixed horizontal plate is connected to the lifting platform by mounting bolts, and a second hydraulic telescopic rod is provided at the middle end of the fixed horizontal plate. The fixed horizontal plate is provided with four sets. The output end of the second hydraulic telescopic rod is equipped with a sleeve, and an abutment seat is provided inside the sleeve. Both the abutment seat and the sleeve are cylindrical.
[0013] Furthermore, a protective partition is fixedly installed at the lower end of the fixed cross plate, and the protective partition is located outside the abutment seat and the sleeve. The protective partition is U-shaped. A limiting groove is opened on the inner side of the sleeve, and the limiting groove is elongated. A movable plate is fixedly installed on the inner side of the abutment seat, and the movable plate is slidably connected to the limiting groove. A damper is provided at the upper end of the movable plate, and the upper end of the damper is fixedly installed at the bottom of the vehicle body.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. When assembling the arched greenhouse frame, align the arc of the bottom of the lifting hook with the arched greenhouse frame. At this time, start the hoist to lift and drive the lifting hook to rise. At this time, the lower end of the arched greenhouse frame contacts the inclined locking block inside the lifting hook, which can quickly block the movement. The long lifting hook can make the tubular arched greenhouse frame be assembled quickly.
[0016] Furthermore, during use, the vehicle body can drive the entire crane to move. After the vehicle body moves to the appropriate position, it can be controlled through the control room at the top of the lifting platform. When the first hydraulic telescopic rod is activated, the lifting end can drive the hoist to adjust the height. The lifting hook at the bottom of the hoist can suspend the arched greenhouse frame, achieving the effect of convenient hoisting of the arched greenhouse frame.
[0017] Furthermore, during hoisting, the arched greenhouse frame presses down on the pressure plate under its own weight, causing the pressure plate to move downwards. The positioning plate is then pulled by the traction rope. By adjusting the rotation of the positioning plate, the arched greenhouse frame can be positioned. The staggered arrangement of the positioning plates prevents the arched greenhouse frame from swaying during hoisting, improves the stability of the crane hoisting, and allows for rapid assembly of the arched greenhouse frame.
[0018] 2. The fixed cross plate is installed on the surface of the lifting platform on the vehicle body by mounting bolts. When the crane body moves to the position where it needs to be assembled, the four sets of auxiliary support mechanisms can provide support according to the actual situation, further ensuring the lifting stability of the crane. The protective partition is set to cover the outside of the sleeve, protect the auxiliary support mechanism, and improve the service life of the crane. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Example 1: As Figures 1-4 The technical solution shown is a crane for rapid assembly of arched greenhouses. To solve the problem of inconvenient lifting operations, it discloses: a vehicle body 1 and a lifting platform 2 installed on the upper part of the vehicle body 1. The upper part of the lifting platform 2 is provided with a control compartment 3, and a telescopic arm 4 is provided on the outside of the control compartment 3. A connecting end 5 is installed at the output end of the telescopic arm 4, and a first hydraulic telescopic rod 6 is provided at the lower end of the connecting end 5. A lifting end 7 is provided at the lower output end of the first hydraulic telescopic rod 6, and a lifting device 8 is connected to the lower end of the lifting end 7. A rapid assembly mechanism is provided at the lower end of the lifting device 8, enabling rapid assembly of the arched greenhouse frame. The lifting platform 2 and the control compartment 3 are rotatably connected, and the control compartment 3 contains control components. The rapid assembly mechanism includes a retraction compartment 1. 9. The end of the retraction chamber 19 is fixedly installed on the outside of the lifting hook 15, and the lower end of the lifting hook 15 is arc-shaped. An inclined locking block 21 is installed through the inside of the retraction chamber 19, and the middle end of the inclined locking block 21 is installed through the lifting hook 15. A locking spring 22 is provided between the inclined locking block 21 and the retraction chamber 19. The upper and lower sides of the inclined locking block 21 are inclined. A pressure plate 20 is installed through the bottom of the lifting hook 15, and an adjusting positioning plate 23 is rotatably installed inside the lifting hook 15. The adjusting positioning plates 23 are staggered. The inner side of the adjusting positioning plate 23 is connected to the pressure plate 20 by a traction rope. A torsion spring 24 is sleeved on the surface of the adjusting positioning plate 23, and the outer side of the torsion spring 24 is fixedly installed on the outer side of the lifting hook 15.
[0029] In use, the crane is moved by the vehicle body 1. After the vehicle body 1 is moved to the appropriate position, it is controlled by the control cabin 3 at the top of the lifting platform 2. The operator controls the crane from inside the control cabin 3. The control cabin 3 controls the telescopic boom 4 for adjustment through the internal control components. When the telescopic boom 4 is adjusted, the front end of the telescopic boom 4 is connected to the first hydraulic telescopic rod 6 via the connecting end 5. When the first hydraulic telescopic rod 6 is activated, it can drive the hoist 8 to adjust its height through the lifting end 7. The lifting hook 15 at the bottom of the hoist 8 can suspend the arched greenhouse frame, achieving the effect of convenient hoisting of the arched greenhouse frame. When assembling the arched greenhouse frame, the arc of the bottom of the lifting hook 15 is aligned with the arched greenhouse frame. At this time, the hoist 8 is activated to lift and drive the lifting hook 15 to rise. At this time, the lower end of the arched greenhouse frame contacts the inclined locking block 21 inside the lifting hook 15. The inclined locking block 21, in its inclined state, is squeezed outward by the arched greenhouse frame. Pushing the retractable shrink chamber 19 inside until the arched greenhouse frame falls into the lifting hook 15, the locking spring 22 pushes the tilting locking block 21 into the lifting hook 15 for quick locking. The long lifting hook 15 allows the tubular arched greenhouse frame to be quickly assembled. When the tubular arched greenhouse frame falls into the lifting hook 15, the frame presses down on the pressure plate 20 under its own weight, causing the pressure plate 20 to move downwards and pull the adjusting positioning plate 23 through the traction rope. By adjusting the rotation of the adjusting positioning plate 23, the arched greenhouse frame can be rotated and positioned. The staggered arrangement of the adjusting positioning plates 23 prevents the arched greenhouse frame from swaying during hoisting, improving the stability of the crane hoisting. The arched greenhouse frame is assembled quickly. When it is necessary to remove the arched greenhouse frame, it falls to the ground and stops applying pressure to the pressure plate 20. Conversely, the frame moves upwards and detaches through the tilted part at the lower end of the tilting locking block 21, making detachment convenient.
[0030] Example 2: Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7The technical solution shown, based on Embodiment 1, discloses the following to address the issue of poor stability: An auxiliary support mechanism is provided on the surface of the lifting platform 2, and the auxiliary support mechanism includes a fixed horizontal plate 9. The fixed horizontal plate 9 is connected to the lifting platform 2 via mounting bolts 10. A second hydraulic telescopic rod 11 is provided at the middle end of the fixed horizontal plate 9, and four sets of fixed horizontal plates 9 are provided. A sleeve 13 is installed at the output end of the second hydraulic telescopic rod 11, and an abutment seat 14 is fitted inside the sleeve 13. The abutment seat 14 and the sleeve... All 13 are cylindrical. A protective partition 12 is fixedly installed at the lower end of the fixed horizontal plate 9. The protective partition 12 is located outside the abutment seat 14 and the sleeve 13. The protective partition 12 is U-shaped. A limiting groove 16 is opened on the inner side of the sleeve 13. The limiting groove 16 is long and narrow. A movable plate 17 is fixedly installed on the inner side of the abutment seat 14. The movable plate 17 is slidably connected to the limiting groove 16. A damper 18 is provided at the upper end of the movable plate 17. The upper end of the damper 18 is fixedly installed at the bottom of the vehicle body 1.
[0031] The fixed horizontal plate 9 is installed on the surface of the lifting platform 2 on the vehicle body 1 by mounting bolts 10. When the vehicle body 1 of the crane moves to the position where it needs to be assembled, the second hydraulic telescopic rod 11 inside the fixed horizontal plate 9 is activated. The output end of the second hydraulic telescopic rod 11 presses down the sleeve 13. The sleeve 13 drives the internal abutment seat 14 to descend and contact the ground. When the abutment seat 14 is pressed down, the moving plate 17 slides along the limit groove 16, and the damper 18 retracts, thereby achieving the effect of pressing down on the ground. With the setting of four sets of auxiliary support mechanisms, support can be provided according to the actual situation, further ensuring the lifting stability of the crane. With the setting of the protective partition 12, the outside of the sleeve 13 is covered, protecting the auxiliary support mechanism and improving the service life of the crane.
[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
