Description

Technical Field

[0001] This utility model relates to the field of climbing scaffolding, and more specifically, to a climbing scaffolding used in construction site work. Background Technology

[0002] Climbing scaffolding, also known as lifting scaffolding, is a newly developed scaffolding system mainly used in high-rise buildings. It can ascend or descend along the building, offering significant advantages in high-rise construction. Patent publication number CN220768760U discloses a climbing scaffolding system, including a base. The base has two mounting cavities on its inner sides, each containing a length adjustment component. These components are connected to movable seats, which are located on both sides of the base. Two guide rails are slidably mounted on both ends of a first guide rail. One end of a telescopic rod is fixedly connected to both sides of the bottom of the second guide rail. The first telescopic rod is fixedly mounted on both sides of the top of the movable seat. A movable platform is installed inside the first guide rail, with a movable groove at its bottom containing a moving component. This system addresses the problem of currently used climbing scaffolding systems on construction sites, which can only move vertically upwards or downwards. This necessitates workers walking back and forth between the corresponding height positions on the climbing scaffolding when working at different locations at the same height, increasing their safety.

[0003] In existing technologies, the climbing scaffold is deployed horizontally by unfolding from both sides, which facilitates construction work at different positions at the same height. However, due to this deployment method, the components used for bottom support also unfold. Although this provides a certain level of support strength, the overall deployment process occupies too much space and increases the ground area occupied. During construction, some sites may be restricted, preventing the climbing scaffold from being deployed laterally. This increases the limitations of the device's use. Furthermore, the hydraulic rods used for lifting are exposed to the external environment for extended periods. Poor construction conditions cause a large amount of debris and dust to adhere to their surface, affecting the smoothness of their extension and retraction and reducing user comfort. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a climbing frame for construction site construction. It can realize the horizontal deployment of the platform by lifting on the construction site without occupying too much ground space, thereby improving the overall space utilization of the device and its practicality. In addition, the hydraulic lifting rod can be protected throughout the lifting process to prevent excessive dust and debris from adhering to its surface, thus improving the service life of the device.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A climbing scaffold for construction site use includes a base, a hydraulic lifting rod fixedly mounted on the top of the base, a main platform fixedly mounted on the top of the hydraulic lifting rod, and auxiliary platforms slidably mounted on the left and right sides of the main platform. The hydraulic lifting rod includes an outer rod and an inner rod, a protective cover fixedly mounted on the outer wall of the upper end of the inner rod, a motor mounting bracket fixedly mounted on the front of the protective cover, a lifting assembly fixedly mounted inside the motor mounting bracket, several mounting brackets fixedly mounted on the outer wall of the protective cover, and an oil plug detachably mounted on the outer side of the top of the protective cover.

[0009] Furthermore, the side of the sub-platform is provided with a fitting groove, the shape of which is adapted to the shape of the main platform.

[0010] Furthermore, a connecting seat is fixedly installed at the bottom of the sub-platform, and reinforcing ribs are fixedly installed on both the left and right sides of the connecting seat, with the top ends of the two reinforcing ribs fixedly installed on the bottom surface of the sub-platform.

[0011] Furthermore, the lifting assembly includes a dual-head motor, with worm gears fixedly installed at both outer ends of the dual-head motor.

[0016] 3. Beneficial effects

[0017] Compared with existing technologies, the advantages of this utility model are:

[0018] (1) This solution utilizes the lifting component and the connecting seat to effectively use the lifting mechanism to achieve the horizontal deployment of the sub-platform in the space above the base. The ground area occupied by the base remains unchanged, allowing the equipment to be deployed horizontally in some limited spaces, thus improving its practicality. Secondly, the use of reinforcing ribs can effectively ensure the connection strength between the sub-platform and the connecting seat, and also improve the support performance.

[0019] (2) This solution utilizes a protective cover to effectively protect the internal lifting rod as the hydraulic lifting rod rises and falls, preventing it from contacting the external environment and ensuring surface cleanliness. Furthermore, the oil injection groove, in conjunction with the annular groove, can be used to quickly lubricate the internal lifting rod of the hydraulic lifting rod, further ensuring its smoothness during lifting and falling and improving the service life of the device.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] Example 1:

[0030] Please see Figure 1-4 A climbing scaffold for construction site use includes a base 1, a hydraulic lifting rod 2 fixedly installed at the top of the base 1, a main platform 3 fixedly installed at the top of the hydraulic lifting rod 2, and auxiliary platforms 4 slidably installed on the left and right sides of the main platform 3, the hydraulic lifting rod 2 including an outer rod and an inner rod, a protective cover 5 fixedly installed on the outer wall of the upper end of the inner rod, a motor mounting bracket 6 fixedly installed on the front of the protective cover 5, a lifting assembly 7 fixedly installed inside the motor mounting bracket 6, a plurality of mounting brackets 8 fixedly installed on the outer wall of the protective cover 5, and an oil plug 9 detachably installed on the outer side of the top of the protective cover 5;

[0031] It should be noted that the main platform 3 and the secondary platform 4 in this application are the same components as those in the prior art documents. The related mobile working platforms set inside and the guardrail structures set outside are consistent with those in the prior art documents. The fact that the secondary platform 4 and the main platform 3 can slide against each other in this application is also based on the prior art documents. Therefore, this application will not elaborate on the existing mature technology.

[0032] The side of the auxiliary platform 4 is provided with a fitting groove 401, the shape of which is adapted to the shape of the main platform 3. A connecting seat 402 is fixedly installed at the bottom of the auxiliary platform 4. Reinforcing ribs 403 are fixedly installed on both the left and right sides of the connecting seat 402. The tops of the two reinforcing ribs 403 are fixedly installed on the bottom surface of the auxiliary platform 4. The lifting assembly 7 includes a dual-head motor 701. Worms 702 are fixedly installed at both outer ends of the dual-head motor 701. A worm wheel 703 is meshed on the surface of the worm wheel 702. A screw 704 is fixedly installed on the top surface of the worm wheel 703. A transmission block 705 is meshed on the surface of the screw 704. A cylinder 706 is integrally formed on the side of the transmission block 705. A connecting rod frame 707 is rotatably installed inside the cylinder 706. The upper and lower ends of the screw 704 are rotatably installed inside the mounting frame 8. The top of the connecting rod frame 707 and the connecting seat 402 are rotatably connected to each other.

[0033] Specifically, the worm gear 702 and worm wheel 703 can achieve a self-locking function through their own characteristics, preventing them from shifting and causing the secondary platform 4 to shift and slide on the left and right sides of the main platform 3. Secondly, the mounting bracket 8 can limit the rotation of the screw 704 to ensure stable transmission between it and the transmission block 705. The mutual rotational connection of the cylinder 706, the connecting rod frame 707, and the connecting seat 402, combined with the linkage principle, allows the lifting and lowering of the transmission block 705 to be converted into the horizontal movement of the secondary platform 4, without occupying extra horizontal space. Finally, the reinforcing rib 403 strengthens the connection stability and support of the secondary platform 4 and the bottom of the connecting seat 402, ensuring construction safety.

[0034] The top of the protective cover 5 is provided with a fixing groove 501, the bottom of the protective cover 5 is provided with a sleeve groove 502, the middle of the fixing groove 501 is provided with an annular groove 504, one side of the annular groove 504 is provided with an oil filling groove 503 inside the protective cover 5, the outer end of the oil filling groove 503 is adapted to the shape of the oil plug 9, and the sleeve groove 502 is movably sleeved on the surface of the outer rod.

[0035] Specifically, the outer rod of the hydraulic lifting rod 2 is movably connected to the sleeve groove 502 so that it does not affect its own lifting and lowering along with the inner rod. In this process, the surface of the inner rod and the corresponding sliding connection between the inner and outer rods are effectively protected, ensuring the cleanliness of the surface of the inner rod of the hydraulic lifting rod 2. Finally, the oil injection groove 503 and the annular groove 504 allow lubricating oil to directly enter the surface of the inner rod, achieving targeted and effective lubrication. This ensures the smooth operation of the overall lifting and lowering of the hydraulic lifting rod 2 and prevents the main platform 3 from jerking, which would affect its use.

[0036] The working principle of this utility model is as follows: The hydraulic lifting rod 2 is activated, causing the main platform 3 to move upward as a whole. The inner rod of the hydraulic lifting rod 2 moves upward along with the lifting assembly 7 via the protective cover 5. When the auxiliary platform 4 needs to be unfolded at the same height, the dual-head motor 701 is activated, causing the worm gear 702 to rotate. This, in conjunction with the worm wheel 703, causes the screw 704 to rotate, driving the transmission block 705 to move upward. At this time, the cylinder 706, through the connecting rod frame 707 and the connecting seat 402, unfolds the auxiliary platform 4 from the outside of the main platform 3 until it reaches the appropriate position. Then, the dual-head motor 701 is turned off. During the process, the protective cover 5 protects the sliding part and the inner rod of the hydraulic lifting rod 2 throughout. When lubrication is required, the oil plug 9 is removed and lubricating oil is injected. The oil enters the interior of the annular groove 504 through the oil injection groove 503, surrounding the edge of the inner rod to complete the lubrication of the hydraulic lifting rod 2.

[0037] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
