Description

Technical Field

[0001] This invention relates to the field of modular housing hoisting technology, and more specifically, to an expandable mechanical hoisting device. Background Technology

[0002] A modular shelter is a protective, box-shaped work area constructed by organically combining various sturdy materials. Its volume is fixed or expandable. Modular shelters, both domestically and internationally, can be broadly categorized into expandable and non-expandable types. Expandable shelters can be further classified into pull-out and four-panel linkage types based on their structural design, while non-expandable shelters can be classified by size, such as four-meter and six-meter shelters.

[0003] Currently, most existing modular housing lifting equipment uses ropes and hooks to lift the top of the modular housing. The corner pieces of the top of the modular housing are secured by binding and shackles to carry out the lifting and transfer. This method is cumbersome and complicated to operate during lifting, requiring at least 3-4 people to work together. On the other hand, if a rope is not properly tied during the transfer operation, it will cause the entire lifting to sway. In short, this method is not simple and reliable. Summary of the Invention

[0004] The purpose of this invention is to provide an expandable mechanical hoisting device that solves the problems of existing hoisting technologies being cumbersome and complex to operate and having low stability.

[0005] The above-mentioned technical objective of this invention is achieved through the following technical solution: an expandable mechanical hoisting device, including a lifting ring, which is fixedly connected to a horizontal bar via a column, and both ends of the horizontal bar are provided with lugs; a connecting assembly, which is movably connected to the lower part of the horizontal bar via the lugs; and a linkage assembly, which consists of two sets, each set of linkage assemblies being rotatably disposed at both ends of the connecting assembly, with the power input ends of the two sets of linkage assemblies respectively rotatably connected to the two lugs, and the power output ends of the two sets of linkage assemblies being connected to clamping assemblies; wherein, the connecting assembly is used to cooperate with the linkage assembly and the lifting ring to bring the two clamping assemblies closer to or further apart.

[0006] The working principle of this technical solution is as follows: When in use, the crane hook is first used to hook the lifting ring to lift the entire device, and then it is lowered from top to bottom on both sides of the cabin, so that the cabin is located between the two clamping components. During this process, two workers need to pull the two sets of clamping components respectively to make them move away from each other until the clamping components completely wrap around the cabin and then release them. Then the lifting ring is lifted upward. As the crossbar gradually moves away from the connecting component, the connecting component and the linkage component interact with each other, driving the two clamping components to move closer to each other to clamp and fix the cabin, and finally lift it up.

[0007] In summary, the present invention has the following beneficial effects:

[0008] Compared with existing technologies, the scalable mechanical hoisting device of the present invention, through the coordinated arrangement of hoisting rings, crossbars, connecting components, linkage components and clamping components, requires only two workers to complete the hoisting of the cabin. It also eliminates the tedious and complicated rope binding work, thus avoiding various uncertainties caused by human error, such as the overall swaying of the hoisting due to improper binding of a rope. It simplifies the operation and improves the stability and reliability of the hoisting operation.

[0009] Furthermore, the connecting assembly includes a hanging rod, both ends of which are fixedly connected to connecting blocks. The connecting blocks have square holes opened laterally. The hanging rod is movably hung on the lugs at both ends of the crossbar through the square holes on the two connecting blocks. Both ends of the hanging rod are provided with connecting parts. Each set of connecting parts includes a fixing plate fixedly installed on the front and rear sides of the hanging rod. The linkage assembly is rotatably installed between the two fixing plates.

[0010] Furthermore, it also includes a protective component, which includes a limiting hook rotatably disposed on one side of the middle of the crossbar and a limiting pin fixedly disposed on one side of the middle of the hanging rod, and the limiting hook and the limiting pin cooperate with each other.

[0011] Furthermore, each of the linkage components includes a first connecting ear rotatably disposed between two fixed plates via a first pin. One end of the first connecting ear is connected to a second connecting ear via a second pin. The free end of the second connecting ear is rotatably connected to a support ear via a third pin. The clamping component is fixedly connected to the side of the first connecting ear away from the second connecting ear.

[0012] Furthermore, each clamping assembly includes a connecting plate fixedly connected to the first connecting ear, a long longitudinal rod fixedly provided on the side of the connecting plate away from the first connecting ear, and a square frame installed on one side of the long longitudinal rod.

[0013] Furthermore, two long horizontal bars are installed through the inner side of the square frame, and a telescopic rod is slidably installed inside each long horizontal bar, with a tripod fixed at both ends of the telescopic rod.

[0014] Furthermore, a limit plate is fixedly installed on the lower end of both the square frame and the triangular frame near the connecting plate.

[0015] Furthermore, a handle is fixedly installed on the long crossbar.

[0016] Furthermore, two second reinforcing rods are symmetrically and fixedly installed on both sides of the connecting plate and the square frame.

[0017] Furthermore, two first reinforcing rods are symmetrically and fixedly installed on both sides of the lifting ring and the crossbar. Attached Figure Description

[0028] The following is in conjunction with the appendix Figure 1 —9. The present invention will be described in further detail.

[0029] like Figure 1 , Figure 5 and Figure 7As shown in the figure, this embodiment of the invention proposes an expandable mechanical hoisting device, including a lifting ring 1, which is fixedly connected to a crossbar 4 via a column 2, with lugs 10 at both ends of the crossbar 4; a connecting assembly, which is movably connected to the lower part of the crossbar 4 via the lugs 10; and a linkage assembly, which consists of two sets, each set rotatably disposed at both ends of the connecting assembly. The power input ends of the two sets of linkage assemblies are rotatably connected to the two lugs 10, and the power output ends of the two sets of linkage assemblies are each connected to a clamping assembly. The connecting assembly is used to cooperate with the linkage assembly and the lifting ring 1 to bring the two clamping assemblies closer together or further apart.

[0030] The specific workflow is as follows: First, use the crane hook to hook the lifting ring 1 to lift the entire device. Then, lower it from top to bottom on both sides of the cabin, so that the cabin is located between the two clamping components. During this process, two workers need to pull the two sets of clamping components to move them away from each other until the clamping components completely wrap around the cabin and then release them. Then, lift the lifting ring 1 upward. As the crossbar 4 gradually moves away from the connecting component, the connecting component and the linkage component interact with each other, driving the two clamping components to move closer to each other to clamp and fix the cabin, and finally lift it up.

[0031] In this embodiment, by setting up the lifting ring 1, crossbar 4, connecting components, linkage components and clamping components to work together, only two workers are needed to complete the hoisting of the cabin. Moreover, the tedious and complicated rope binding work is eliminated, which avoids the uncertainty of human error such as the overall swaying of the hoisting due to a rope not being properly bound. This simplifies the operation and improves the stability and reliability of the hoisting operation.

[0032] In actual use, in order to further improve the overall stability of the device, two first reinforcing rods 3 can be symmetrically and fixedly installed on both sides of the lifting ring 1 and between the crossbar 4.

[0033] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, according to another embodiment of the present invention, an expandable mechanical hoisting device is provided, wherein the connecting assembly includes a hanging rod 5, both ends of which are fixedly connected to connecting blocks 9. The connecting blocks 9 are laterally provided with square holes. The hanging rod 5 is movably hung on the lugs 10 at both ends of the crossbar 4 through the square holes on the two connecting blocks 9. Both ends of the hanging rod 5 are provided with connecting parts. Each set of connecting parts includes a fixing plate 15 fixedly disposed on the front and rear sides of the hanging rod 5. The linkage assembly is rotatably disposed between the two fixing plates 15.

[0034] This solution achieves the transmission connection between the crossbar and the linkage assembly by setting up the hanging rod 5, the connecting block 9, the fixing plate 15, and the two lugs 10 of the crossbar 4 to cooperate with each other.

[0035] like Figure 1 , Figure 4 , Figure 7 and Figure 9 As shown, according to another embodiment of the present invention, an expandable mechanical hoisting device further includes a protective component, the protective component including a limiting hook 22 rotatably disposed on one side of the middle portion of the crossbar 4 and a limiting pin 23 fixedly disposed on one side of the middle portion of the hanging rod 5, wherein the limiting hook 22 and the limiting pin 23 cooperate with each other.

[0036] This solution uses a combination of limit hook 22 and limit pin 23 to limit the closest distance between the two clamping components, thereby protecting the sidewall of the enemy cabin.

[0037] like Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, according to another embodiment of the present invention, an expandable mechanical hoisting device is provided, wherein each set of the linkage components includes a first connecting ear 14 rotatably disposed between two fixed plates 15 via a first pin 13, one end of the first connecting ear 14 is connected to a second connecting ear 12 via a second pin, and the free end of the second connecting ear 12 is rotatably connected to a support ear 10 via a third pin 11, wherein the clamping component is fixedly connected to the side of the first connecting ear 14 away from the second connecting ear 12.

[0038] This solution involves setting up a first connecting ear 14, a second connecting ear 12, a first pin 13, a second pin, and a third pin 11 to work together to drive the two clamping components via the crossbar 4.

[0039] like Figure 1 and Figure 3 As shown, according to another embodiment of the present invention, an expandable mechanical hoisting device is provided, wherein each set of clamping assemblies includes a connecting plate 6 fixedly connected to a first connecting ear 14, a long longitudinal rod 21 fixedly disposed on the side of the connecting plate 6 away from the first connecting ear 14, and a square frame 19 mounted on one side of the long longitudinal rod 21.

[0040] This scheme uses a long longitudinal bar 21, a square frame 19, a connecting plate 6, and a first connecting lug 14 to work together to clamp the container and thus complete the hoisting operation.

[0041] In actual use, to improve the flexibility of hoisting operations, two long horizontal bars 18 can be installed through the inner side of the square frame 19. A telescopic bar 17 is slidably installed inside each long horizontal bar 18, and a triangular frame 16 is fixedly installed at both ends of the telescopic bar 17. Then, a limiting plate 8 is fixedly installed on the side of the lower end of the square frame 19 and the triangular frame 16 near the connecting plate 6. At the same time, a rubber pad can be installed on the top of the limiting plate 8, and the limiting plate 8 supports the bottom of the cabin, making the overall reliability of the hoisting operation higher. During hoisting, the telescopic bar 17 can be stretched or contracted according to the actual length of the cabin, and the telescopic bar 17 can be limited by means of pins, etc., to accommodate cabins of different lengths. To facilitate workers to pull the square frame 19, a handle 7 can be fixedly installed on the long horizontal bar 18. To further improve the stability between the square frame 19 and the connecting plate 6, two second reinforcing bars 20 can be symmetrically and fixedly installed on both sides of the connecting plate 6 and between the square frame 19.

[0042] In summary, the detailed working process of this invention is as follows:

[0043] 1. For example Figure 1 and Figure 3 As shown, firstly, the crane hook is used to hook the lifting ring 1 to lift the entire device, and then it is lowered from top to bottom to both sides of the container. During this process, two workers simultaneously pull the handles 7 on the two long horizontal bars 18 to move the two square frames 19 away from each other until the container is completely enclosed. Then, the handles 7 are pushed to bring the two square frames 19 closer together, while ensuring that the limiting plate 8 can support the bottom of the container. The rubber pad on the top of the limiting plate 8 can improve the enclosure of the container. Then, the crane pulls the rope upward, causing the lifting ring 1 and the horizontal bar 4 to move upward. Figure 2 and Figure 8 As shown, as the crossbar 4 moves upward away from the hanging bar 5, the left support lug 10 starts to drive the left second connecting lug 12 to pull the first connecting lug 14 to rotate counterclockwise. Similarly, the right support lug 10 drives the right second connecting lug 12 to pull the first connecting lug 14 to rotate clockwise. The square frames 19 on both sides thus gain the force to move closer to each other, and then cooperate with the bottom limiting plate 8 to clamp the container tightly. The whole process is convenient to operate, highly stable, simple and reliable.

[0044] 2. Setting limit hooks 22 and limit pins 23 at the middle of the crossbar 4 and hanging rod 5 respectively can limit the closest distance between the two square frames 19, preventing the side walls of the container from being excessively clamped and damaged. Figure 1 , Figure 4 , Figure 7 and Figure 9As shown, by controlling the distance between the limit pin 23 and the limit hook 22, the maximum distance between the crossbar 4 and the hanging rod 5 can be controlled. Once this distance is exceeded, the limit hook 22 and the limit pin 23 will begin to assist in controlling the hanging rod 5, so as to prevent the two square frames 19 from getting too close and damaging the side wall of the container.

[0045] It should be noted that the specification attached to this application... Figure 1 —9 To make the comparison clearer, the maximum (minimum) distance between the two square frames 19 is exaggerated, and does not represent the actual working situation.

[0046] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
