Description

Technical Field

[0001] This utility model relates to the technical field of hydraulic construction lifting platforms, specifically to a foldable hydraulic construction lifting platform. Background Technology

[0002] In the construction of water conservancy projects, foldable hydraulic construction lifting platforms play a vital role. From the construction and maintenance of dams to the dredging and regulation of river channels, and the installation and maintenance of hydropower stations, many construction stages rely on the assistance of lifting platforms. For example, when carrying out anti-seepage treatment and crack repair work on the surface of the dam, construction workers need to use lifting platforms to reach the corresponding height and carry out construction operations accurately. This not only improves construction efficiency but also reduces the risks of working at height, enabling water conservancy projects to proceed more efficiently and safely.

[0003] Traditional lifting platforms typically have fixed guardrails, which cannot be folded and stored when the platform is idle or being transported, further increasing the space occupied by the equipment. The installation and dismantling of these fixed guardrails require a lot of tools and manpower, making the operation process cumbersome, time-consuming, and labor-intensive, which not only delays the construction period but also increases labor costs. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a foldable hydraulic construction lifting platform, which can effectively solve the problem that the guardrails of the existing lifting platform cannot be folded and stored, resulting in the equipment being idle or occupying a lot of space during transportation.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] This utility model provides a foldable hydraulic construction lifting platform, including a lifting platform body;

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0022] The present invention will be further described below with reference to the embodiments.

[0023] Example: Refer to Figures 1 to 4 A foldable hydraulic construction lifting platform, including the lifting platform body 1;

[0024] Two folding mechanisms are provided, each including a guardrail folding assembly 2 and a limiting assembly 3. The guardrail folding assembly 2 includes a fixed post 21 fixedly connected to the upper surface of the lifting platform body 1. The side wall of the fixed post 21 is provided with two limiting holes 22 and 23. A bearing plate 24 is fixedly connected to the upper surface of the lifting platform body 1. A rotating shaft 25 is provided above the lifting platform body 1. The rotating shaft 25 passes through and is rotatably connected to the side wall of the fixed plate. A rotating post 26 is fixedly connected to the side end of the rotating shaft 25. The upper end face of the rotating post 26 is fixedly connected to the guardrail body 27. The rotating post 26 is close to the fixed plate. A limit pin 28 is fixedly connected to one side wall of the column 21. A turntable 29 is fixedly connected to the end of the rotating shaft 25 away from the rotating column 26, which facilitates operation by the staff. The two limit pins 28 are respectively matched with two first limit holes 22 and second limit holes 23. The two first limit holes 22 and second limit holes 23 are equidistant from the axis of the rotating column 26. The rotating column 26, the rotating shaft 25 and the turntable 29 are all concentrically arranged. The sum of the heights of the two guardrail bodies 27 is less than the width of the upper surface of the lifting platform body 1, which allows the folding function of the guardrail body 27 to be used normally.

[0025] The limiting component 3 includes a fixed plate 31 fixedly connected to the side wall of the fixed column 21, a rotating sleeve 32 rotatably sleeved on the outside of the rotating column 26 via a bearing, a guide plate 33 fixedly connected to the side wall of the rotating sleeve 32, two guide rods 34 fixedly connected to the side wall of the fixed plate 31 near the guide plate 33, the guide plate 33 slidably sleeved on the two guide rods 34, and two springs 35 fixedly connected between the guide plate 33 and the fixed plate 31, the two springs 35 respectively sleeved on the two guide rods 34.

[0026] The working principle of this utility model is as follows: At the construction site of a water conservancy project, the lifting platform body 1 is placed in a suitable position to ensure that the bottom of the platform is in stable contact with the ground. When the lifting platform needs to be used for work, the operator holds the turntable 29 and applies a pulling force to it, so that the rotating column 26 separates from the fixed column 21, and the limiting pin 28 also disengages from the restriction of multiple limiting holes. Then, the turntable 29 is rotated according to the unfolding direction of the guardrail body 27. The turntable 29 drives the rotating shaft 25 to rotate, and the rotating shaft 25 in turn drives the rotating column 26 to rotate around its axis. When the rotating column 26 rotates to a suitable angle, so that the limiting pin 28 is aligned with the first limiting hole 22, under the action of the spring 35, the limiting pin 28 is inserted into the first limiting hole 22, fixing the guardrail body 27 in the unfolded state. At this time, the guardrail body 27 provides safety protection for the construction personnel.

[0027] When construction is completed or the lifting platform needs to be transported, the operator holds the turntable 29 and pulls it again to disengage the limit pin 28 from the first limit hole 22. Then, the turntable 29 is rotated in the opposite direction, and the rotating column 26 drives the guardrail body 27 to rotate. When the rotating column 26 rotates until the limit pin 28 is aligned with the second limit hole 23, the turntable 29 is released. The elastic force of the spring 35 will drive the rotating column 26 to move towards the fixed column 21, thereby allowing the limit pin 28 to insert into the second limit hole 23, completing the folding of the guardrail body 27 and fixing the folded guardrail body 27. At this time, the sum of the heights of the two guardrail bodies 27 is less than the width of the upper surface of the lifting platform body 1, which facilitates transportation and storage.

[0028] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
