Description

Technical Field

[0001] This utility model relates to the field of construction platform technology, specifically to a safe construction platform for building engineering. Background Technology

[0002] During construction, when it is necessary to carry out work at heights, a lifting construction platform is usually used to facilitate the operation of workers at heights. The standing area on the lifting construction platform is fixed, and the range of operation for construction workers is limited. Construction workers are often limited by the area of ​​the platform and need to move around to reach the construction position. Therefore, casters are installed on the base of the construction platform to facilitate movement.

[0003] However, while the casters make it convenient to move the construction site, they also pose a risk of the platform shifting when workers walk on it. Although the casters have a self-locking mechanism, the friction is not high enough because the casters are in line contact with the ground, so it is still not safe enough. Therefore, we propose a safe construction platform.

[0004] The information disclosed in the background section is only intended to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0005] The purpose of this invention is to provide a safety platform that automatically makes surface contact with the ground when construction workers are lifting and lowering the platform, thereby increasing friction and preventing the construction platform from moving when users walk on it, thus solving the above-mentioned shortcomings in the technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a construction safety platform, comprising a lifting platform of a scissor lift construction platform, two sets of scissor lift structures, a base, self-locking moving wheels, and a hydraulic cylinder. The moving wheels are installed around the outer wall of the base. The scissor lift structure consists of multiple scissor lifts, with the uppermost scissor lift rotatably connected to the bottom of the lifting platform. The output end and tail of the hydraulic cylinder are rotatably mounted with connecting rods, and both connecting rods are rotatably connected to the two sets of scissor lift structures. The base has a vertical through hole, and a ground contact element is slidably connected within the through hole. A spring is fixedly installed on the top of the ground contact element, and an mounting plate is fixedly installed on the top of the spring. Connecting shafts are fixedly installed on both sides of the mounting plate. The connecting shafts simultaneously pass through the two lowest scissor lifts in an adjacent set of scissor lift structures and are rotatably connected to the scissor lifts. The end of the connecting shaft is fixedly connected to the inner wall of the base, and the ends of the two lowest scissor lifts of the scissor lift structure are in contact with the top surface of the ground contact element.

[0007] Preferably, the ground contact component includes a contact plate that contacts the ground and two guide plates fixedly connected to the top of the contact plate. There is a sliding gap between the two guide plates. The connecting shaft passes through the sliding gap and does not contact the guide plates. Both the guide plates and the contact plates are slidably connected to the through hole.

[0008] Preferably, the bottom of the lifting platform has a downward-opening receiving cavity, the height of the ground contact member is greater than the height of the base, and when the bottom surface of the contact plate is higher than the bottom surface of the base, the top of the guide plate is located inside the receiving cavity.

[0009] Preferably, when the hydraulic cylinder output shaft is in its longest extension state, the bottom surface of the contact plate is higher than the bottom surface of the base; when the hydraulic cylinder output shaft is in its shortest extension state, the top surface of the guide plate is higher than the bottom surface of the base.

[0010] Preferably, when the output shaft of the hydraulic cylinder is in its longest extended state, the hydraulic cylinder does not contact the mounting plate.

[0011] Preferably, the bottom surface of the contact plate has anti-slip texture.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0013] 1. When the lifting platform is driven to rise by the scissor lift structure, the ground contact component will be driven to slide downward in the base at the same time. When the ground contact component comes into contact with the ground, it generates surface friction. Compared with the line friction generated by the moving wheels in the existing technology, it can generate greater friction force, which can prevent the platform from moving when construction workers walk on the lifting platform and provide safety.

[0014] 2. When the lifting platform is raised, the ground contact component automatically lifts the base to generate friction with the ground, thus automatically increasing the friction without additional control. This ensures that high friction will be automatically generated in dangerous environments such as working at heights, thus enhancing the safety of construction workers.

[0015] 3. When the lifting platform descends to a certain height, the spring gradually drives the ground contact component to retract into the base, and the ground contact component no longer generates friction with the ground, thus realizing the function of automatic reset.

[0023] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0025] This utility model provides, for example Figure 1-4The diagram illustrates a construction safety platform, comprising a scissor lift platform 1, two sets of scissor structures 2, a base 3, self-locking casters 4, and a hydraulic cylinder 5. The casters 4 are mounted around the outer wall of the base 3. The bottom of the lift platform 1 has a downward-opening receiving cavity 12. The scissor structure 2 consists of multiple scissor rods 2a, with the uppermost scissor rod 2a rotatably connected to the bottom of the lift platform 1. Connecting rods 6 are rotatably mounted at both the output end and the tail of the hydraulic cylinder 5. Both connecting rods 6 are rotatably connected to the two sets of scissor structures 2. The base 3 has a vertical through hole 7, within which a ground contact element 8 is slidably connected. The ground contact element 8 includes a contact plate 8a that contacts the ground and two guide plates 8b fixedly connected to the top of the contact plate 8a. The bottom surface of the contact plate 8a has anti-slip textures. The height of the ground contact 8 is greater than the height of the base 3. When the bottom surface of the contact plate 8a is higher than the bottom surface of the base 3, the top of the guide plate 8b is located in the receiving cavity 12. There is a sliding gap 8c between the two guide plates 8b. A spring 9 is fixedly installed on the top of the contact plate 8a. A mounting plate 10 is fixedly installed on the top of the spring 9. A connecting shaft 11 is fixedly installed on both sides of the mounting plate 10. The connecting shaft 11 passes through the two lowest scissor bars 2a in an adjacent set of scissor structures 2 and is rotatably connected to the scissor bars 2a. The connecting shaft 11 passes through the sliding gap 8c and does not contact the guide plate 8b. The guide plate 8b and the contact plate 8a are slidably connected to the through hole 7. The end of the connecting shaft 11 is fixedly connected to the inner wall of the base 3. The ends of the two lowest scissor bars 2a in the scissor structure 2 are in contact with the top surface of the ground contact 8.

[0026] Initial state: The user moves the platform to the construction position that needs to be raised and lowered using the caster 4. At this time, the output shaft of the hydraulic cylinder 5 is in its longest extension state. The hydraulic cylinder 5 is not in contact with the mounting plate 10, and the top of the guide plate 8b is inside the receiving cavity 12, while the bottom surface of the contact plate 8a is above the bottom surface of the base 3.

[0027] Preparation stage: The user drives the output shaft of hydraulic cylinder 5 to shorten, and the output shaft of hydraulic cylinder 5 drives the scissor structure 2 to extend. At this time, the uppermost scissor bar 2a of the scissor structure 2 drives the lifting platform 1 to rise, and the lowermost scissor bar 2a end contacts the top surface of the contact plate 8a and rotates around the connecting shaft 11, thereby pressing the contact plate 8a downward. The contact plate 8a drives the guide plate 8b to slide downward in the through hole 7. When the contact plate 8a extends out of the base 3 and contacts the ground, the output shaft of hydraulic cylinder 5 stops shortening. At this time, the contact plate 8a makes surface contact with the ground. Compared with the line contact between the moving wheel 4 and the ground after self-locking, the friction generated is greater. There is no need to worry about the moving wheel 4 driving the lifting platform 1 to move during operation. The staff goes to the lifting platform 1 to prepare.

[0028] During use: The operator can continue to drive the output shaft of hydraulic cylinder 5 to shorten so that the lifting platform 1 can be raised. Alternatively, the output shaft of hydraulic cylinder 5 can be extended midway to lower the height, thus ensuring safe construction on the lifting platform 1.
