Embodiment 1
[0041] Such as Figure 1 to Figure 3As shown, a backing plate hoisting unit illustrated in this example is used for hoisting a backing plate with a hoisting hole, and the hoisting hole vertically runs through the upper and lower surfaces of the backing plate in the thickness direction; the backing plate hoisting unit includes a support frame 1, an upper suspender , Lower davit and locking part 4, the upper davit is suspended and supported on the support frame 1, the upper end of the lower davit is detachably connected with the lower end of the upper davit, thereby forming an upper and lower structure, which is convenient for the separation of the upper davit and the lower davit connect with;
[0042] The upper hanging column includes an upper outer tube 23 and an upper inner shaft 21 arranged coaxially, there is a gap between the upper outer tube 23 and the upper inner shaft 21, and the upper inner shaft 21 can rotate and axially rotate relative to the upper outer tube 23. mo...
other Embodiment approach
[0060] In other embodiments, the linkage 39 may not be provided, and a spring is arranged on the guide rod 38, and the spring is pressed between the upper outer tube 23 and the inner side of the compression block 37. After being restrained, the pressing block 37 is reset outward by a spring.
[0061] see Figure 4 and Figure 6As shown, the third driving mechanism is installed on the upper outer tube 23, including a support base 31, a second cylinder 32, a second rotating arm 35, a second support arm 34 and a second connecting arm 33, and the support base 31 is installed on the upper outer tube. On the pipe 23, the second cylinder 32 and the second support arm 34 are installed on the support base 31, the first end of the second arm 35 is connected to the expansion sleeve 36 in rotation, and the middle part of the second arm 35 is supported on the second support. arm 34, and is connected with the second supporting arm 34 in rotation, the second end of the second rotating arm ...
Embodiment 2
[0063] In this example, the function of synchronous lifting of the inner shaft and the outer tube is added on the basis of the first example, and the rest of the structure is the same as that of the first example.
[0064] Such as Figure 13 to Figure 15 As shown, since the outer tube and the inner shaft are to be lifted and lowered synchronously, the mounting base 61 is supported on the driving device 7 that drives the lifting base 66 up and down, and the upper end of the upper outer tube 23 is fixed with a connecting base 71, and the lifting base 66 is connected to the Seat 71 is all connected with described driving device 7, specifically, lifting seat 66 is supported on the driving device 7 by connecting seat 71; Supported on the connecting seat 71, it can be raised and lowered relative to the connecting seat 71, so that the lifting seat 66 is driven up and down by the second driving mechanism, that is, the lifting of the inner shaft is realized; the driving device 7 drives...

Abstract
The invention belongs to the technical field of auxiliary construction facilities, and relates to a backing plate hoisting unit, which includes a support frame, an upper suspension column, a lower suspension column and a locking piece; the upper suspension column is connected to the support frame, and the lower suspension column is detachably connected to the upper suspension column; The upper hanging column includes an upper outer tube and an upper inner shaft arranged coaxially. The upper inner shaft can rotate and move axially relative to the upper outer tube. The lower hanging column includes a lower outer tube and a lower inner shaft that can be lifted; the upper outer tube and the lower The outer tube is detachably connected, and the upper inner shaft and the lower inner shaft are detachably connected through a thread structure; the support frame is provided with a second drive mechanism for driving the inner shaft to rise and fall relative to the outer tube; the locking piece is connected to the lower end of the lower outer tube , and rotationally fit; a conversion structure is provided between the lower end of the lower inner shaft and the locking piece, which converts the lifting movement of the lower inner shaft into the rotational movement of the locking piece. The invention divides the hanging column into upper and lower parts. Before laying, the lower hanging column is pierced in a stack of backing plates. When laying, the upper hanging column is directly connected with the lower hanging column to realize quick connection.
Description
technical field [0001] The invention belongs to the technical field of auxiliary construction facilities, and in particular relates to a backing plate hoisting unit. Background technique [0002] The high-strength composite backing plate is a kind of plate used for quickly building platforms or passages. It can provide a strong, durable and flat "ground" in a short time, which can meet the traffic and stability of heavy equipment and be used for ground protection. It is suitable for special and complex ground conditions, such as beach, swamp, tundra, inland grassland, Gobi desert, etc. [0003] At present, in the on-site construction of backing boards, various equipment such as cranes, forklifts, loaders, and a large number of operators are usually required to cooperate with the construction to realize the unloading of backing boards, transfer to the laying site, lifting a single backing board to the laying position, Manual alignment, laying flat, moving to find the correct...
