The lifting assembly 2 adjusts the height of the construction basket to accommodate transitions between different construction locations, thereby better meeting the construction needs of various areas.

[0027] The support assembly 3 is disposed between the foundation base and the construction site, transferring the load downward to the construction site, thereby improving the stability of the entire device and preventing it from tipping over during construction, particularly when the construction basket is at a high height. Preferably, the support assemblies 3 are arranged in pairs symmetrically about the foundation base, with a set of support assemblies 3 being symmetrically disposed on either side of the foundation base.

[0031] Preferably, a door opening can be left at the side end of the protective frame 104, and the opening and closing door 105 can be embedded in the door opening using a rotating hinge to facilitate the opening and closing of the opening and closing door 105, thereby facilitating the construction workers to enter and exit the construction basket.

[0032] Please see the attached Figure 2The basic base includes a structural plate 101 and universal wheels 102 , and a plurality of universal wheels 102 are installed at intervals on the bottom surface of the structural plate 101 ; the lower end of the lifting assembly 2 is installed on the top surface of the structural plate 101 .

[0033] Preferably, the structural plate 101 can be made of a square steel frame and thick steel plates, which has high structural strength and strong load-bearing capacity to ensure the load-bearing capacity and stability of the entire device. If necessary, a counterweight block can be configured on the structural plate 101 to lower the center of gravity and further improve the stability of the entire device during use.

[0034] Preferably, the universal wheel 102 may be a universal wheel with a braking structure to ensure that the universal wheel can roll flexibly while being reliably braked at the construction position to avoid accidental slipping during the construction process.

[0035] Please see the attached Figure 3 The lifting assembly 2 includes a first connecting block 202, a scissor-type lifting frame 203, a second connecting block 204 and a lifting and moving mechanism; the upper end of the scissor-type lifting frame 203 is mounted on the bottom surface of the base plate 103 through a plurality of first connecting blocks 202, and the lower end of the scissor-type lifting frame 203 is mounted on the top surface of the structural plate 101 through a plurality of second connecting blocks 204, so that the construction basket can be lifted and lowered above the foundation base through the scissor-type lifting frame 203; the lifting and moving mechanism is connected to the bottom of the scissor-type lifting frame 203.

[0036] Preferably, two groups of scissor lifts 203 can be provided, or more than two groups can be provided depending on actual load requirements. The scissor lift 203 is composed of multiple X-shaped lifting frames that are rotatably connected. The top and bottom ends of the scissor lift 203 are fixedly mounted on the base plate 103 and the structural plate 101, respectively. The other top and bottom ends of the scissor lift 203 are slidably mounted on the base plate 103 and the structural plate 101, respectively, via slide rails and sliders, thereby meeting its lifting and folding requirements. The scissor lift 203 is a commonly used lifting control mechanism in the art, and its specific structure and operating principle will not be detailed here.

[0037] Preferably, the first connecting block 202 and the second connecting block 204 can adopt a U-shaped bracket structure, the first connecting block 202 is inverted and fixedly connected to the bottom surface of the base plate 103 through a horizontal section, and the top end of the scissor lift 203 is rotatably connected between the vertical sections of the first connecting block 202 through a rotating shaft; similarly, the horizontal section of the second connecting block 204 is fixedly connected to the top surface of the structural plate 101, and the bottom end of the scissor lift 203 is rotatably connected between the vertical sections of the second connecting block 204 through a rotating shaft, which facilitates the installation of the scissor lift 203 between the structural plate 101 and the base plate 103 and their relative rotation requirements.

[0038] The first connecting block 202 at the other end of the top of the scissor lift 203 is used as a slider, and a slide rail is installed at a corresponding position on the bottom surface of the base plate 103. The second connecting block 204 at the other end of the bottom of the scissor lift 203 is used as a slider, and a slide rail is installed at a corresponding position on the top surface of the structural plate 101, thereby realizing the expansion and folding of the scissor lift 203, and further realizing the lifting function of the construction basket.

[0039] Please see the attached Figure 3 The lifting and moving mechanism includes a connecting plate 205 and a moving rod 206. The connecting plate 205 is installed on the second connecting block 204 at the other end of the bottom of the scissor-type lifting frame 203. The moving rod 206 is movably inserted into the connecting plate 205. The moving rod 206 is arranged parallel to the top of the structural plate 101.

[0040] Preferably, two connecting plates 205 are provided, and a moving rod 206 vertically extends through the two connecting plates 205. The moving rod 206 can be a hydraulic rod or a pneumatic rod to achieve a push-pull motion, thereby driving the second connecting block 204 at the other end of the bottom of the scissor lift 203 to move horizontally, thereby achieving motion control of the scissor lift 203 and locking it at a specified height.

[0041] The movable rod 206 and the connecting plate 205 can also adopt a threaded rotation connection method based on motor drive or manual drive, or other existing connection methods can be adopted according to actual usage requirements, so that the horizontal movement and locking functions of the movable rod 206 can be realized. The relevant structures and their working processes will not be described here one by one.

[0042] Please see the attached Figure 3 The lifting assembly 2 also includes a lifting rod 207 and a spring sleeve 208; the fixed end of the lifting rod 207 is fixedly mounted on the top surface of the structural plate 101, and the telescopic end of the lifting rod 207 is fixedly mounted on the bottom surface of the base plate 103; the spring sleeve 208 is coaxially sleeved on the lifting rod 207, and the two ends of the spring sleeve 208 are respectively connected to the fixed end and the telescopic end of the lifting rod 207.

[0043] Preferably, the lifting rod 207 can be a two-section splice rod. The two sections, namely the fixed end and the telescopic end, can slide relative to each other to extend or shorten during the lifting of the construction basket. Damage to the scissor lift 203 could cause the construction basket to fall. This would cause the two sections of the splice rod to slide and shorten. The relative movement of the fixed and telescopic ends compresses the spring sleeve 208, which then uses the elastic force generated by the deformation of the spring sleeve 208 to cushion the fall, reducing the speed and impact of the fall and improving the safety of the construction basket.

[0044] Please see the attached Figure 3The lifting assembly 2 also includes a fixed plate 201, the top surface of the fixed plate 201 is fitted and connected to the bottom surface of the base plate 103, the upper end of the scissor-type lifting frame 203 is mounted on the bottom surface of the fixed plate 201 through a plurality of first connecting blocks 202; the telescopic end of the lifting rod 207 is fixedly mounted on the bottom surface of the fixed plate 201.

[0045] The fixed plate 201 is in surface contact with the bottom plate 103, which can greatly improve the support stability of the lifting assembly 2 on the construction basket, and also facilitate the installation and arrangement of the first connecting block 202 at the top of each group of scissor-type lifting frames 203 and the telescopic end of the lifting rod 207.

[0046] Please see the attached Figure 4 The support assembly 3 includes a mounting plate 301, a rotating shaft 302, a rotating sleeve 303 and a supporting mechanism; a pair of mounting plates 301 are fixedly mounted on the side walls of the structural plate 101, and the rotating shaft 302 is vertically fixedly connected between a pair of parallel mounting plates 301 to form a group of mounting seats; several groups of mounting seats are respectively installed on the side walls of the structural plate 101 at intervals, and several rotating sleeves 303 are respectively installed on the supporting mechanism at intervals, and several rotating sleeves 303 are respectively correspondingly sleeved on the rotating shafts 302 of several groups of mounting seats, so that a pair of supporting mechanisms can be rotatably arranged on both sides of the structural plate 101.

[0047] Preferably, the mounting plate 301 , the rotating shaft 302 , and the rotating sleeve 303 can all be made of high-strength materials such as steel to avoid deformation and damage after being subjected to force.

[0048] When the support mechanism rotates, the rotating sleeve 303 rotates relative to the rotating shaft 302, the mounting plate 301, and the structural plate 101, enabling the support structure to be installed and rotated on the structural plate 101. When the support mechanism is rotated horizontally, it is separated from the construction site, without affecting the flexible movement of the entire device via the universal wheels 102. When the support mechanism is rotated vertically, it can be used to support the construction site, improving the stability of the foundation and effectively preventing the entire device from tipping over.

[0049] Please see the attached Figure 4 Each group of the supporting mechanisms includes a telescopic plate 304 and a support rod 305; the fixed end of the telescopic plate 304 is fixedly connected to multiple rotating sleeves 303 located on the same side of the structural plate 101, and a plurality of support rods 305 are arranged at intervals at the telescopic end of the telescopic plate 304. The ends of the plurality of support rods 305 away from the telescopic plate 304 can be supported on the construction site below the side of the structural plate 101.

[0050] Preferably, the telescopic plate 304 comprises a hollow, bottom-open fixed plate made of steel and a solid, movable plate inserted into the hollow fixed plate. The solid, movable plate and the hollow fixed plate are connected by pneumatic or hydraulic telescopic rods. The solid, movable plate can be telescoped and raised relative to the hollow fixed plate by varying air or oil pressure. The width of the telescopic plate 304 can be aligned with the width of the structural plate 101 to enhance support. Since the telescopic rods 304 are elongated, an appropriate number of pneumatic or hydraulic telescopic rods can be spaced according to their width to ensure the smooth movement of the solid, movable plate.

[0051] Preferably, the support rods 305 can be made of square steel pipes, and the support rods 305 are symmetrically installed at both ends of the bottom of the solid movable plate. The number of support rods 305 can also be appropriately increased according to support requirements to ensure support stability.

[0052] The end of the support rod 305 away from the telescopic plate 304 is provided with an anti-skid pad (not shown in the figure), so that the end of the support rod 305 away from the telescopic plate 304 abuts against the construction site through the anti-skid pad.

[0053] Preferably, the anti-slip pad can be made of rubber material, which can increase the friction between the support rod 305 and the construction site, and further improve the supporting effect.

[0054] Please see the attached Figure 1 To the attached Figure 4 , the usage method and working principle of the utility model are:

[0055] Move the entire device to the construction location, lock the universal wheels 102, open the door 105, and the construction workers can enter the construction basket. The bottom plate 103 provides support and construction space for the construction workers, and the protective frame 104 provides safety protection for the construction workers.

[0056] Rotate the telescopic plate 304 to rotate the rotating sleeve 303 relative to the rotating shaft 302, rotate the telescopic plate 304 to a vertical state, and at the same time extend the telescopic end of the telescopic plate 304 downward so that the bottom of the support rod 305 is supported on the ground through the anti-slip pad, thereby improving the setting stability of the entire device through the four support rods 305 on both sides of the structural plate 101.

[0057] The scissor lift 203 can be expanded or retracted by pushing or pulling the movable rod 206 , so that the height of the construction basket can be adjusted by expanding or retracting the scissor lift 203 to meet construction requirements at different heights.

[0058] After one construction is completed, the vehicle can be moved to the next construction location via the universal wheels 102 and the above-mentioned actions can be repeated to continue the construction work.

[0059] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
