[0031] The base 1 includes a base 101 and a supporting seat 102 movably arranged on the top of the base 101. The supporting seat 102 can be placed on the top of the base 101 and moved up and down mainly relying on the jacking device 103, the guide rod 101-1 and the guide kit 102-1. Specifically, as shown in the figure, Figures 1-2 ​As shown, the jacking device 103 is connected between the supporting seat 102 and the base 101, which can adopt any device or kit that can provide jacking force and lift the supporting seat 102, such as a hydraulic drive device 303, a pneumatic cylinder, etc. In the embodiment, the jacking device 103 adopts a hydraulic rod, one end of which is installed on the base 101, and the other end is installed on the guide sleeve 102-1 of the supporting seat 102. In the embodiment, two guide rods 101-1 are arranged on the base 101, and accordingly, two sets of guide sleeves 102-1 are arranged on the supporting seat 102, which are sleeved on the guide rods 101-1 to enable the supporting seat 102 to be guided and limited by the guide rods 101-1 to move up and down in the vertical direction. In the embodiment, the guide sleeve 102-1 used is a guide sleeve rod structure, which has an inner cavity in which the guide rod 101-1 on the base 101 can be received.

[0032] As shown, Figures 1-2 The support column 2 is vertically arranged on the supporting seat 102. In the embodiment, since the guide sleeve 102-1 adopts the guide sleeve rod structure, the support column 2 is fixedly installed on the guide sleeve rod. This structure enables the support column 2 to have a larger contact area with the supporting seat 102, thereby enhancing the connection firmness between the support column 2 and the supporting seat 102. Figures 1-2 As shown,

[0033] As shown, Figures 1-2 The hoisting device 3 comprises an extension frame 301, a hoisting cable 302, and a drive device 303. One end of the extension frame 301 is movably connected with the support column 2, and the other end is provided with a first guide pulley 304. The movable connection of the extension frame 301 only needs to ensure that the extension frame 301 can rotate axially around the movable mounting point, and thus any structure can be used, such as a hinge connection structure. In the embodiment, the axis of the axial rotation is parallel to the central axis of the support column 2. The drive device 303 is arranged on the base 1, and in the embodiment, the drive device 303 is installed on the supporting seat 102. One end of the hoisting cable 302 is wound around the receiving disc of the drive device 303, and the other end passes through a second guide pulley 305 arranged on the support column 2 and the first guide pulley 304 in sequence to form a hoisting fixed part 302a, which can be sleeved on the ALC panel to form a relative fixation with the panel.

[0034] The use process of the ALC panel adjustable hoisting device in the embodiment is as follows:

[0035] Firstly, after placing the adjustable hoisting device of ALC plate to the designated position, the jacking device 103 is started to drive the supporting seat 102 to lift, and then drive the supporting column 2 to lift, until the top of the supporting column 2 closely abuts against the ceiling of the construction site. At this time, the base 101 and the top of the supporting column 2 respectively abut against the ground and the ceiling of the construction site, achieving the fixation of the whole adjustable hoisting device of ALC plate, avoiding the subsequent side turning and other situations in the vertical work of ALC plate.

[0043] Embodiment 2:

[0044] The difference between the ALC plate adjustable hoisting device in this embodiment and the embodiment 1 is that, as shown in Figures 1-2 As shown, the bottom of the support seat 102 is provided with four groups of first universal wheel kits 102-3. As shown in Figure 2 As shown, when the jacking device 103 is retracted, the support seat 102 is closely combined with the base 101, and finally the first universal wheel kit 102-3 supports the ALC plate adjustable hoisting device as a whole.

[0045] In the vertical work of the ALC plate, due to the influence of factors such as the area of the construction site, there is a situation that the plate transverse storage position is far away from the final installation point of the plate, therefore, under the structure in this embodiment, the ALC plate adjustable hoisting device carries out the initial vertical work of the plate, without lifting the support seat 102 and the support column 2 thereon through the jacking device 103, keeping the first universal wheel kit 102-3 on the ground, that is, keeping the ALC plate adjustable hoisting device in a state capable of displacement, then fixing the hoisting fixed part 302a and the ALC plate, preliminarily lifting the plate to make it suspended, and then the construction personnel cooperate to push the ALC plate and the ALC plate adjustable hoisting device to the vicinity of the installation point of the ALC plate, and finally starting the jacking device 103 to fix the ALC plate adjustable hoisting device and carry out the subsequent vertical work.

[0046] Preferably, as Figures 1-2As shown, the base 1 also comprises a locking set 104 arranged on the base 101 and the supporting seat 102, which is used to lock the relative position of the supporting seat 102 and the base 101 when the supporting seat 102 is close to the base 101.

[0047] The locking set 104 can adopt any component or set that can realize the position locking of the base 101 and the supporting seat 102, for example, a plate with a bolt hole is arranged on the sidewall of the base 101, and a bolt hole is arranged on the sidewall of the supporting seat 102, when the two are close to each other, the two sets of bolt holes are aligned, and the bolt can be inserted to ensure the relative position between the base 101 and the supporting seat 102.

[0050] In the vertical process of the ALC plate, it needs to be kept in an inclined state for a long time, and the inclination angle will change gradually according to the progress of the vertical work, so that the plate may be dragged on the ground during the vertical process; at the same time, when the ALC plate adjustable hoisting device adjusts the position of the plate, the plate may be excessively displaced due to its own inertia and finally collide with the surrounding structure. The above situations may cause damage to the ALC plate, especially the lack of corners and angles.

[0051] ​​And in the setting has the bearing car A, the construction personnel can control the bearing car A to cooperate to erect the work through the cart handle A04, to solve the above problem. Specifically, the second universal wheel assembly A02 in the bearing car A can provide support on the ground on the one hand, on the other hand also makes the bearing plate A01 can rotate around the second universal wheel assembly A02, so the board placed on the bearing car A can adjust the inclination of the bearing car A when the inclination angle changes, guarantee the bearing plate A01 can always support the bottom of the board and the board side A03 can support the sidewall of the board. Further not only avoid the board vertical and the situation of dragging the ground during the process of adjusting the position, but also make the board not easy to shake left and right after being supported, thereby reducing the collision with other structures and other situations, reducing the possibility of damage to the board.

[0052] Finally, it should be noted that: the above implementation cases are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing implementation cases, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing implementation cases, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the implementation cases of the present application.
