Description

Technical Field

[0001] This invention relates to the field of civil engineering technology, specifically to a lifting-type aerial work platform suitable for steel structure construction. Background Technology

[0002] In the construction of multi-story and high-rise steel structures, commonly used welding, bolting, and other construction equipment and consumables need to be stored and transferred via high-altitude equipment platforms that accompany each floor. As the construction floors rise, these platforms require vertical transportation using tower cranes, which takes up a significant amount of time and significantly impacts the construction progress. Furthermore, the platforms are heavy, and improper material storage management can lead to uneven stress on the lifting points during hoisting, causing deformation and weld fatigue. This results in significant structural safety hazards and high risks for personnel working at heights.

[0003] To solve the above problems, in application number... CN202210540424.1 The patent discloses a "high-altitude top-lifting self-elevating integrated intelligent toolbox and its construction method". It has a first lifting device and a second lifting device on both sides of the bottom of the box where personnel work. The electric screw in the first lifting device extends vertically relative to the steel beam and abuts against the crossbeam at the bottom of the box to lift the box to the elevation of the steel beam of the next floor. Then, the telescopic outriggers in the first and second lifting devices extend horizontally and vertically and are placed on the steel beam of the next floor, thereby completing the climbing of one layer of steel beams and reducing the risk of personnel working at height.

[0004] However, the existing toolkit for improving performance has the following safety risks:

[0005] Firstly, existing lifting toolboxes rely solely on the bottom electric lead screw to support the box during the climbing process, which can lead to unreliability due to pressure on the bottom electric lead screw.

[0006] Secondly, the existing lifting toolboxes rely solely on a power unit to remain fixed, and this single power structure also affects the reliability of the lifting toolboxes.

[0007] Therefore, improving the reliability of high-altitude lifting toolboxes is a problem that needs to be solved in this field. Summary of the Invention

[0008] In view of the technical problem of low reliability of existing lifting toolboxes, the purpose of this invention is to provide a lifting-type aerial work platform suitable for steel structure construction, which can solve the technical problems of existing lifting toolboxes, improve the reliability of aerial work platforms, and effectively overcome the problems existing in the prior art.

[0009] To achieve the above objectives, the present invention provides a lifting-type aerial work platform suitable for steel structure construction, comprising a housing, a first lifting device, and a second lifting device; the first lifting device is disposed on the top of the housing and moves vertically relative to the housing, and a first telescopic rod that cooperates with a steel beam is disposed on the top of the first lifting device; the second lifting device comprises two sets of lifting components, which are disposed opposite to each other on both sides of the housing and can move parallel to the side wall of the housing, and a second telescopic rod that cooperates with a steel beam is disposed opposite to each other on the two sets of lifting components.

[0010] Furthermore, the box body is composed of a structural frame and several panels, which are attached to the structural frame to form the entire box body structure.

[0011] Furthermore, the structural frame is a three-dimensional structure composed of several central columns, several corner columns, and several horizontal columns spliced ​​together; the top of the several central columns is provided with mounting holes and the interior is a hollow structure.

[0012] Furthermore, the first lifting device includes several sets of first lifting components; the several sets of first lifting components are arranged opposite each other on the top of the box, and each set of first lifting components is connected by a first longitudinal beam to form an integral structure.

[0013] Furthermore, the first lifting assembly includes a first crossbeam, a first drive motor, a plurality of first lead screws, and a plurality of first lead screw jacks;

[0014] The first crossbeam is positioned opposite to the top of the box, and the interior of the first crossbeam is a hollow structure for installing the first telescopic rod; the first drive motor is mounted on the first crossbeam and drives the first telescopic rod connected inside the first crossbeam, and the first drive motor can drive the first telescopic rod inside the first crossbeam to extend and retract along both ends of the first crossbeam respectively.

[0015] One end of the first lead screw is installed in the mounting hole of the central column, and the other end is connected to the first crossbeam. The first lead screw jack is connected to the first lead screw, and the first lead screw can be driven to extend and retract within the central column.

[0016] Furthermore, the second lifting assembly includes a second crossbeam, a second drive motor, a hydraulic cylinder, and a slide bar;

[0017] One end of the slide rod is fixed to the housing, and the other end passes through the second crossbeam and is fixed to the housing. The hydraulic cylinder is mounted on the housing, and the piston rod inside the hydraulic cylinder drives the second crossbeam, causing the second crossbeam to move up and down along the slide rod. The interior of the second crossbeam is a hollow structure for mounting the second telescopic rod. The second drive motor is mounted on the second crossbeam and drives the second telescopic rod inside the second crossbeam.

[0030] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below with reference to specific illustrations.

[0031] In view of the technical problem of low reliability of existing lifting toolboxes, this invention provides a lifting-type aerial work platform suitable for steel structure construction, which can solve the technical problems of existing lifting toolboxes and improve the reliability of aerial work platforms.

[0032] The present invention provides a lifting-type aerial work platform suitable for steel structure construction, see [link to relevant documentation]. Figure 1 It includes a housing 1, a first lifting device and a second lifting device.

[0033] The container 1 is equipped with an entrance and exit, and the interior is the work space for staff. Staff can enter and exit the container 1 through the entrance and exit, and high-altitude operations can be achieved by lifting the container 1.

[0034] Box 1 is composed of a structural frame and a panel. The panel is placed on the structural frame to form the entire box.

[0035] See Figure 2 The structural frame consists of four central columns 15, four corner columns 16, and several horizontal columns 14 spliced ​​together. The top of the four central columns 15 is provided with mounting holes, and the central columns 15 are hollow structures for connection with the first lifting device.

[0036] The structure of housing 1 is well known to those skilled in the art, and will not be described in detail here.

[0037] The first lifting device is located on the top of the housing 1 and includes several sets of first lifting components 2. The several sets of first lifting components 2 are arranged opposite to each other on the top of the housing 1 and can lift and support the housing 1.

[0038] Furthermore, each first lifting assembly 2 includes a first crossbeam 21, a first telescopic rod 22, a first drive motor 23, a plurality of first lead screws 24, and a plurality of first lead screw jacks 25.

[0039] The first crossbeams 21 are positioned opposite each other on the top of the box body 1. The two first crossbeams 21 are connected by the first longitudinal beam 26 to form a whole, which can ensure the stability of the structure.

[0040] Each first crossbeam 21 has a hollow interior structure, which is used to house the first telescopic rod 22. The first telescopic rod 22 is placed inside the first crossbeam 21 and works in conjunction with the first drive motor 23. The first drive motor 23 is mounted on the first crossbeam 21 and drives the first telescopic rod 22 connected inside the first crossbeam 21. The first drive motor 23 can drive the first telescopic rod 22 inside the first crossbeam 21 to extend and retract along both ends of the first crossbeam 21.

[0041] When in operation, the first drive motor 23 can drive the first telescopic rod 22 to extend outward synchronously through both ends of the first crossbeam 21, forming an extension section of the first crossbeam 21, which can be mounted on the steel beam; conversely, the first drive motor 23 can drive the first telescopic rod 22 to retract inward synchronously through both ends of the first crossbeam 21, detaching from the steel beam.

[0042] The two ends of the first crossbeam 21 are connected to the box body 1 through the first screw rod 24. Several first screw rods 24 are located on the top of the box body 1 and are distributed on both sides of the box body 1. One end of the first screw rod 24 is connected to the central column 15, and the other end is connected to the first crossbeam 21.

[0043] A number of first screw jacks 25 are connected to drive first screws 24. The first screw jacks 25 can drive the first screws 24 to extend and retract relative to the central column 15, thereby adjusting the height of the first crossbeam 21.

[0044] Specifically, when the first telescopic rod 22 detaches from the steel beam, the first lead screw 24 extends and retracts under the drive of the first lead screw jack 25, which can adjust the vertical distance between the first crossbeam 21 and the first telescopic rod 22 relative to the box body 1.

[0045] The number of first screw jacks 25 is not limited here. They can correspond to the number of first screws 24 and drive and control each first screw 24 independently. Alternatively, several motors can be linked through a commutator to control several first screw jacks 25. The specific number can be determined according to the actual situation.

[0046] The second lifting device includes two sets of second lifting components 3, which are symmetrically arranged on both sides of the box body 1. Each set of second lifting components 3 includes a second crossbeam 31, a second telescopic rod 32, a second drive motor 33, a hydraulic cylinder 35, a slide bar 36, and an anti-fall component.

[0047] Furthermore, the slide rods 36 are arranged opposite each other on both sides of the housing 1, with one end fixed to the housing 1 and the other end passing through the opening on the second crossbeam 31 and fixed to the housing 1. The second crossbeam 31 can move along the slide rods 36 on both sides.

[0048] The hydraulic cylinder 35 is mounted on the housing 1. The piston rod 34 inside the hydraulic cylinder 35 drives the second crossbeam 31 to move up and down along the slide rod 36, thereby adjusting the height of the second crossbeam 31 on the slide rod 36.

[0049] The second crossbeam 31 has a hollow interior structure, which is used to house the second telescopic rod 32. The second telescopic rod 32 is placed inside the second crossbeam 31 and works in conjunction with the second drive motor 33. The second drive motor 33 is mounted on the second crossbeam 31 and drives the second telescopic rod 32 connected inside the second crossbeam 31. The second drive motor 33 can drive the second telescopic rod 32 inside the second crossbeam 31 to extend and retract along both ends of the second crossbeam 31.

[0050] When in operation, the second drive motor 33 can drive the second telescopic rod 32 to extend outward synchronously through both ends of the second crossbeam 31, forming an extension section of the second crossbeam 31, which can be mounted on the steel beam; conversely, the second drive motor 33 can drive the second telescopic rod 32 to retract inward synchronously through both ends of the second crossbeam 31, detaching from the steel beam.

[0051] In addition, after the crossbeam is erected on the steel beam, a fall protection component is installed to ensure the stability of the crossbeam on the steel beam. The fall protection component includes a mounting base, a fall protection plate 11, a third drive motor 12, a spring plate, and a steel wire rope 13.

[0052] The fall arrestor plate 11 is mounted on the mounting base, and the steel wire rope 13 is respectively mounted on both ends of the fall arrestor plate 11 and connected to the third drive motor 12. By rotating the third drive motor 12, the steel wire rope 13 can be wound and unwound, thereby extending and retracting the fall arrestor plate 11.

[0053] A spring is positioned between the mounting base and the fall arrestor plate 11. When the wire rope 13 contracts the fall arrestor plate 11, the fall arrestor plate 11 exerts a force on the spring plate. When the wire rope 13 relaxes, due to the restoring force of the spring plate, the fall arrestor plate 11 will pop out and press on the second crossbeam 31, thus limiting the movement of the second crossbeam 31.

[0054] Furthermore, the above solution is achieved by using... Figure 2 The hydraulic power of the hydraulic cylinder drives the second crossbeam 31 and the second telescopic rod 32 to move up and down along the slide rod 36. This solution, in addition to hydraulic drive, also provides a power drive solution to ensure greater stability of the device. Therefore, this second lifting assembly 3 also includes an electric drive assembly. See [link to documentation]. Figure 3 The electric drive assembly includes a second lead screw 37 and a second lead screw jack 38.

[0055] The second lead screw 37 is disposed opposite to the two sides of the housing. One end of the lead screw is connected to the corner of the top of the housing 1, and the other end passes through the second crossbeam 31 and is connected to the corner of the bottom of the housing 1. The second lead screw jack 38 is disposed on the second crossbeam 31 and is connected to the second crossbeam 31.

[0056] The second screw jack 38 can move axially a certain distance along the second screw 37, and during the movement, it drives the second crossbeam 31 to rise and fall along the second screw 37 to adjust the vertical distance of the second crossbeam 31 relative to the housing 1.

[0057] The specific control structure is not limited in this scheme; it can be controlled electrically or hydraulically, depending on the actual situation.

[0058] The following example illustrates the working process of this utility model in a specific application. It should be noted that the content described here is only a specific application example of this solution and does not constitute a limitation on this solution.

[0059] See Figure 4 In operation, the second crossbeam 31 is located at the bottom of the slide bar 36, and the second telescopic rod 32 extends under the drive of the second drive motor 33. The machine room is erected on the Nth layer steel beam 41 through the second telescopic rod 32. At the same time, the steel wire rope 13 is released, allowing the anti-fall plate 11 to be ejected and pressed on the upper surface of the second crossbeam 31 to limit its movement.

[0060] The first lead screw 24 is fully retracted into the middle column 15 under the drive of the first lead screw lifting motor 25, and the first telescopic rod 22 is fully retracted into the first crossbeam 21 under the drive of the first drive motor 23.

[0061] When the machine room is being raised, the first lead screw 24, driven by the first lead screw lifting motor 25, extends out of the middle column 15 and drives the first crossbeam 21 to rise to the top elevation of the steel beam 42 on the N+1 floor. Then, the first drive motor 23 drives the first telescopic rod 22 to extend out of the first crossbeam 21 and be erected on the steel beam 42 on the N+1 floor.

[0062] Then the second drive motor 33 drives the second telescopic rod 32 to retract completely into the second crossbeam 31, and then the third drive motor retracts the anti-fall plate 11 inward to prevent it from blocking the crossbeam 31 from moving upward.

[0063] The second crossbeam 31 moves upward along the slide bar 36 driven by the hydraulic cylinder 35 until it is at the top of the slide bar 36. At this point, the second crossbeam is above the elevation of the N+1 layer steel beam 42. Then, the second telescopic rod 32 extends, and the second crossbeam 31 moves downward along the slide bar 36. The second telescopic rod 32 contacts the N+1 layer steel beam 42 and is mounted on the N+1 layer steel beam 42. The first telescopic rod 22 disengages from the N layer steel beam 41 and is retracted into the first crossbeam 21.

[0064] Finally, the second crossbeam 31 continues to move downward along the slide bar 36, while the box 1 moves upward in the opposite direction, until the second crossbeam 31 is located at the bottom of the slide bar 36, and the anti-fall plate 11 extends outward to press against the upper surface of the side wall crossbeam 31. At this point, the platform completes one climb.

[0065] The above-described lifting-type aerial work platform, suitable for steel structure construction, has the following advantages over existing aerial lifting toolboxes:

[0066] (1) The lifting-type high-altitude work room is a mechanized transformation and upgrade of the traditional high-altitude equipment platform. It can achieve stable self-climbing through its own mechanical power device. Compared with the current equipment platform that requires tower crane to transfer it layer by layer, it does not require tower crane time and can improve the efficiency of on-site steel structure construction.

[0067] (2) The climbing mechanism of the high-altitude work room adopts the lifting force method. Two sets of lifting devices are added to the equipment platform: the top lifting device and the side wall lifting device, which realizes the self-climbing of the whole process lifting method, solves the problem of the stability of the thin rod under pressure in the traditional climbing process, and greatly improves the safety performance of the work room.

[0068] (3) The side wall lifting device in this scheme is either hydraulically driven or electrically driven. The hydraulically driven method has the characteristics of strong stability and strong waterproofness, while the electrically driven method has the characteristics of lower cost and simple structure.

[0069] (4) In addition, this solution proposes a side beam anti-fall device that can be driven by a motor, so that the side beam does not rely solely on the power device to remain fixed during operation.

[0070] (5) The high-altitude work room serves as a transfer station for commonly used construction equipment and consumables, which facilitates the standardized management of construction equipment and materials on site. At the same time, its semi-enclosed compartment space is not affected by the high-altitude climate environment, forming a safe house for high-altitude workers.

[0071] In summary, this platform features light weight, does not rely on tower cranes or personnel for high-altitude assistance, and achieves stable self-climbing through its own power unit, thus realizing the goal of safe, reliable, fast, and convenient platform self-climbing.

[0072] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
