Description

Technical Field

[0001] This utility model relates to the field of building construction platform technology, and more specifically to an adjustable building construction platform. Background Technology

[0002] A lifting platform is a type of lifting machinery that vertically transports people or goods. It also refers to equipment used for vertical transport in logistics systems such as factories and automated warehouses. In addition to transporting goods at different heights, it is also widely used for high-altitude installation, maintenance, and other operations. In construction sites or building decoration work, lifting construction platforms are often needed in places where it is not possible to directly work on the top of a building or at a high altitude. They are used to vertically transport people or goods or to perform high-altitude operations.

[0003] A search revealed an existing patent (publication number: CN218346736U) that discloses a height-adjustable building construction platform. During use, a drive motor rotates a threaded rod, enabling the workbench to move vertically up and down. A drive assembly simultaneously rotates two first screws, facilitating height adjustment. Once adjusted, the first motor drives two second screws via a first belt and two first pulleys, extending the threaded plate into the building. A steel wire rope then secures the threaded plate to the building, enhancing stability and allowing workers to walk directly from the threaded plate into the building. This facilitates the transport of vehicles, etc. The structure is simple and very convenient to use. However, the inventors discovered the following problems with the existing technology during the development of this utility model: In the above-mentioned construction platform, the workbench is threaded onto the surface of the threaded rod. During the lifting and lowering process of the construction platform, since the threaded rod is directly connected to the drive motor, if a power outage occurs during the lifting and lowering process, the drive motor will lose power. If the drive motor lacks a self-locking effect or the self-locking effect of the drive motor is not timely, the construction platform will fall. This poses a certain safety hazard during use. On the other hand, when workers are working on the surface of the workbench, the side closer to the building is easily affected by dust generated from the construction on the building surface, which can obstruct the view and hinder the safe construction of workers working at height.

[0004] In view of this, this utility model proposes a height-adjustable building construction platform to solve this problem. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an adjustable building construction platform to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: an adjustable building construction platform, including a base, with movable wheels provided on the bottom side of the base, a lifting platform provided above the base, and a lifting drive assembly provided between the base and the lifting platform, with an inlet and outlet on the surface of the lifting platform, and protective doors hinged to the inlet and outlet on the surface of the lifting platform, and dust protection components and extension components respectively provided on the surface of the lifting platform corresponding to the inlet and outlet.

[0007] The lifting drive assembly includes two rectangular sleeves symmetrically fixedly installed on the upper surface of the base. A lifting column is slidably connected to the top of the rectangular sleeves, and a lifting screw is rotatably connected to the inner bottom wall of the two rectangular sleeves. The threads of the two lifting screws are opposite in direction. The lifting column is threadedly connected to the surface of the lifting screw. A drive box is fixedly installed on the surface of the base. A lifting motor is fixedly installed on the surface of the drive box. A transmission rod is rotatably connected to the surface of the drive box. The end of the transmission rod extends into the interior of the rectangular sleeve and is connected to the lifting screw via a bevel gear. The output shaft of the lifting motor extends into the interior of the drive box and is fixedly installed with a worm gear. A worm wheel is fixedly installed on the surface of the transmission rod, and the worm gear meshes with the worm wheel.

[0008] The dust suppression and protection component includes two connecting pipes fixedly installed on the surface of the lifting platform. The two connecting pipes are symmetrically arranged on the left and right sides of the front of the lifting platform. The bottom end of the connecting pipe is fitted with a connector, which is connected to an external water pipe. The surface of the connecting pipe is provided with water spray holes.

[0009] Furthermore, four limiting sleeves are fixedly installed on the surface of the base in a rectangular array. The top of the limiting sleeve is slidably connected to a limiting slide rod, and the top of the limiting slide rod is fixed to the bottom of the lifting platform. By setting the limiting sleeves and limiting slide rods, the movement path of the lifting platform can be restricted, thereby improving the stability of the lifting platform's lifting and moving.

[0010] Furthermore, the base has two symmetrically threaded adjusting screws on its surface. Each adjusting screw has an anti-slip support plate rotatably connected to its bottom end, and a limit rod is fixedly installed on the top of the anti-slip support plate, with the limit rod slidably connected to the base. When used by construction personnel, by setting the adjusting screws and anti-slip support plates, the base can be pushed to the construction area using the moving wheels. Rotating the adjusting screws allows the anti-slip support plates to contact the ground, improving the stability of the base and reducing the likelihood of slippage.

[0011] Furthermore, the extension assembly includes a storage slot inside the inlet / outlet, an extension pedal is slidably connected inside the storage slot, a servo motor is fixedly installed on the back of the lifting platform, the output shaft of the servo motor extends into the storage slot and is fixedly installed with a drive screw, and the extension pedal is threadedly connected to the surface of the drive screw; by setting the extension pedal, when workers are working on the surface of the lifting platform, the servo motor drives the drive screw to rotate, which allows the extension pedal to extend to the outside and be erected on the surface of the external structure, facilitating personnel to walk between the lifting platform and the external building and to carry tools.

[0012] Furthermore, a ladder is fixedly installed at the bottom of the lifting platform, and the ladder corresponds to the position of the entrance and exit; when construction personnel use it, the workers can climb onto the lifting platform via the ladder, making operation convenient.

[0013] Furthermore, a controller is fixedly installed on the inner wall of the lifting platform; the operator connects the controller to the external mains power and uses the controller to control the entire device.

[0014] Furthermore, the surface of the lifting platform is provided with a pin rod, and the surface of the protective door is provided with a pin hole. The pin rod is adapted to the pin hole, and the surface of the lifting platform is provided with a return spring that drives the pin rod to abut against the inside of the pin hole. When the operator uses the platform, the elastic force of the return spring is used to insert the pin rod into the pin hole, keeping the protective door locked. The protective door can improve the safety of the operator when on the surface of the lifting platform.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1. This utility model allows workers to stand on the surface of a lifting platform. A lifting drive assembly is installed, using a lifting motor to drive a worm gear, which in turn drives a worm wheel and transmission rod. Under the transmission of bevel gears, the lifting screw rotates, driving the lifting column to move within a rectangular sleeve, thus adjusting the height of the lifting platform. During this process, the self-locking effect of the worm gear and worm wheel provides fall protection in the event of a power outage, improving the safety of workers performing work at height. Furthermore, during construction, the connector is connected to an external water supply, allowing water to spray from the nozzles through a connecting pipe, effectively reducing dust generated during construction on the building surface, maintaining clear visibility for workers, and further ensuring their safety.

[0017] 2. This utility model, by setting a limiting sleeve and a limiting slide rod, can restrict the movement path of the lifting platform, thereby improving the stability of the lifting platform's lifting and moving movement; by setting an adjusting screw and an anti-slip support plate, after the base is pushed to the construction area using the moving wheels, rotating the adjusting screw and using the anti-slip support plate to contact the ground can improve the stability of the base and reduce the possibility of the base sliding; by setting an extension pedal, when workers are working on the surface of the lifting platform, the servo motor drives the drive screw to rotate, allowing the extension pedal to extend to the outside and be erected on the surface of the external structure, facilitating personnel movement and tool handling; by using the elastic force of the return spring, the pin is inserted into the pin hole, keeping the protective door locked, thereby improving the safety of the operator.

[0024] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The adjustable building construction platform involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] Reference Figure 1-5 This utility model provides an adjustable building construction platform, including a base 1, and a set of casters 2 on the bottom side of the base 1.

[0026] The base 1 has two adjusting screws 15 symmetrically threaded on its surface. The bottom of each adjusting screw 15 is rotatably connected to an anti-slip support plate 16, and a limit rod 17 is fixedly installed on the top of the anti-slip support plate 16. The limit rod 17 is slidably connected to the base 1.

[0027] When used by construction workers, by setting the adjusting screw 15 and the anti-slip support plate 16, the base 1 is pushed to the construction area by the moving wheel 2. By rotating the adjusting screw 15, the anti-slip support plate 16 is brought into contact with the ground, which can improve the stability of the base 1 and reduce the slippage of the base 1.

[0028] A lifting platform 3 is provided above the base 1, and a lifting drive assembly is provided between the base 1 and the lifting platform 3. An inlet and outlet are provided on the surface of the lifting platform 3.

[0029] A human ladder 21 is fixedly installed at the bottom of the lifting platform 3, and the position of the human ladder 21 corresponds to that of the entrance and exit.

[0030] When used by construction workers, they can easily climb onto the lifting platform 3 via the human ladder 21.

[0031] A controller 22 is fixedly installed on the inner wall of the lifting platform 3.

[0032] After moving to the construction area, the staff connected the controller 22 to the external mains power and used the controller 22 to control the entire device.

[0033] The surface of the lifting platform 3 is hinged with a protective door 4 corresponding to the inlet and outlet.

[0034] The surface of the lifting platform 3 is provided with a pin rod 23, and the surface of the protective door 4 is provided with a pin hole, and the pin rod 23 is adapted to the pin hole.

[0035] The surface of the lifting platform 3 is provided with a return spring 27 that abuts against the inside of the drive pin rod 23 and the pin hole.

[0036] When in use by staff, the spring force of the return spring 27 is used to insert the pin rod 23 into the pin hole, keeping the protective door 4 locked. The protective door 4 can improve the safety of the operator when on the surface of the lifting platform 3.

[0037] The surface of the lifting platform 3 is equipped with dust protection components and extension components corresponding to the inlet and outlet.

[0038] The lifting drive assembly includes two rectangular sleeves 5 symmetrically fixedly mounted on the upper surface of the base 1. A lifting column 6 is slidably connected to the top of the rectangular sleeve 5, and a lifting screw 7 is rotatably connected to the inner bottom wall of the two rectangular sleeves 5.

A drive box 8 is fixedly mounted on the surface of the base 1. A lifting motor 9 is fixedly mounted on the surface of the drive box 8. A transmission rod 18 is rotatably connected to the surface of the drive box 8. The end of the transmission rod 18 extends into the interior of the rectangular sleeve 5 and is connected to the lifting screw 7 via a bevel gear. The output shaft of the lifting motor 9 extends into the interior of the drive box 8 and is fixedly mounted with a worm gear 19. A worm wheel 20 is fixedly mounted on the surface of the transmission rod 18, and the worm gear 19 meshes with the worm wheel 20.

[0039] Workers stand on the surface of the lifting platform 3. Through the lifting drive assembly, the lifting motor 9 drives the worm gear 19 to rotate, which in turn drives the worm wheel 20 and the transmission rod 18 to rotate. Under the transmission action of the bevel gear, the lifting screw 7 can be driven to rotate, which in turn drives the lifting column 6 to move inside the rectangular sleeve 5 to adjust the height of the lifting platform 3. During this process, the self-locking effect of the worm gear 19 and the worm wheel 20 can protect the lifting platform 3 from falling in the event of an accidental power failure, thereby improving the safety of operators working at height.

The bottom end of the connecting pipe 24 is fitted with a connector 25, which is connected to an external water pipe. The surface of the connecting pipe 24 is provided with water spray holes 26.

[0041] During construction, workers connect connector 25 to an external water supply, allowing water to be sprayed from nozzle 26 through connecting pipe 24. This achieves the purpose of dust suppression for construction work on building surfaces, maintains clear visibility for workers at the lifting platform 3 position, and further ensures the safety of workers during construction.

[0042] The surface of the base 1 is fixedly equipped with four limiting sleeves 13 in a rectangular array. The top of the limiting sleeves 13 is slidably connected to the limiting slide rods 14, and the top of the limiting slide rods 14 is fixed to the bottom of the lifting platform 3.

[0043] By setting the limiting sleeve 13 and the limiting slide bar 14, the movement path of the lifting platform 3 can be restricted, thereby improving the stability of the lifting and moving of the lifting platform 3.

[0044] The extension assembly includes a storage slot inside the inlet and outlet, an extension pedal 10 is slidably connected inside the storage slot, a servo motor 11 is fixedly installed on the back of the lifting platform 3, the output shaft of the servo motor 11 extends into the storage slot and a drive screw 12 is fixedly installed thereon, and the extension pedal 10 is threadedly connected to the surface of the drive screw 12.

[0045] By setting up an extension pedal 10, when workers are working on the surface of the lifting platform 3, the servo motor 11 drives the drive screw 12 to rotate, which allows the extension pedal 10 to extend to the outside and be erected on the surface of the external structure, making it convenient for personnel to walk between the lifting platform 3 and the external building and to carry tools.

[0046] Finally, it should be noted that the accompanying drawings of the embodiments disclosed in this utility model only involve the structures involved in the embodiments disclosed in this utility model.
