Description

Technical Field

[0001] The utility model relates to the technical field of hoisting and installation construction in various construction projects, and particularly relates to a simple corrugated guardrail installation trolley. Background Art

[0002] The installation of traditional corrugated guardrail plates is mostly manual. Workers need to hold the corrugated guardrail plates by hand for operation. Since the corrugated guardrail plates are long and heavy, a large number of workers are required. Moreover, as the physical strength is consumed, the installation progress decreases. Not only is the efficiency low, but also the corrugated guardrail plates are likely to fall due to severe physical consumption during the construction process, which is likely to cause potential safety hazards. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a simple, efficient and safe simple corrugated guardrail installation trolley.

[0004] To solve the above problems, a simple corrugated guardrail installation trolley of the utility model is characterized in that: the installation trolley is composed of two symmetric single-body devices on the left and right. Each single-body device includes a walking system and a horizontal steel frame and a vertical steel frame which are connected together and placed on the walking system; a hook is arranged at one end of the horizontal steel frame, and a handrail is arranged at the other end.

[0005] The horizontal steel frame is perpendicular to the vertical steel frame and is connected together by a diagonal brace I.

[0006] The walking system is composed of an axle and wheels installed at both ends of the axle; the axle is perpendicular to the vertical steel frame and is connected together by a diagonal brace II.

[0007] The horizontal steel frame is perpendicular to the handrail, and the handrail is parallel to the axle.

[0008] The ratio of the distance from the hook to the connection of the horizontal steel frame and the vertical steel frame to the distance from the connection of the horizontal steel frame and the vertical steel frame to the handrail is 1:6.

[0009] The utility model has the following advantages compared with the prior art:

[0010] 1. By using the lever principle, the utility model makes it easier and more labor-saving to lift heavy objects such as guardrail plates.

[0011] 2. The utility model uses a hook to lift the corrugated guardrail plate. Workers control the hook through the horizontal steel frame, and the workers do not directly contact the corrugated guardrail plate, reducing the risk of the corrugated guardrail plate falling and injuring construction workers and reducing potential safety hazards during operation.

[0012] 3. The lower part of the utility model adopts a wheel walking system, which is convenient for horizontal transportation of corrugated guardrail plates over a slightly longer distance and saves labor.

[0013] 4. This utility model is made of steel pipes and small wheels, with simple production, low cost and good safety, and is suitable for the installation operation of corrugated guardrails. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The following further describes in detail the specific embodiments of the present utility model in conjunction with the drawings.

[0018] As Figures 1 - 2 shown, a simple corrugated guardrail installation trolley is composed of two symmetric single devices on the left and right. Each single device includes a traveling system and a horizontal steel frame 1 and a vertical steel frame 2 connected together on the traveling system. A hook 7 is provided at one end of the horizontal steel frame 1, and a handrail 8 is provided at the other end.

[0019] Among them: The horizontal steel frame 1 is perpendicular to the vertical steel frame 2 and is connected together by a diagonal brace Ⅰ 3. It uses the lever principle to save effort and reduce the working load.

[0020] The traveling system is composed of an axle 4 and wheels 6 installed at both ends of the axle 4; the axle 4 is perpendicular to the vertical steel frame 2 and is connected together by a diagonal brace Ⅱ 5. Using the traveling system is convenient for the horizontal transportation of corrugated guardrails and saves physical strength.

[0021] The horizontal steel frame 1 is perpendicular to the handrail 8, and the handrail 8 is parallel to the axle 4.

[0022] The ratio of the distance from the hook 7 to the connection of the horizontal steel frame 1 and the vertical steel frame 2 to the distance from the connection of the horizontal steel frame 1 and the vertical steel frame 2 to the handrail 8 is 1:6.

[0023] Both the horizontal steel frame 1 and the vertical steel frame 2 are made of φ50*6mm steel pipes; the traveling system can use finished wheels; the diagonal brace Ⅰ 3, the diagonal brace Ⅱ 5 and the handrail 8 are all made of φ42*4 steel pipes. Welding connections are used between the various connectors.

[0024] When in use, push the trolley of the utility model to both sides of the corrugated guardrail plate. Pass the lifting hook 7 through the anti-theft bolt holes on both sides of the corrugated guardrail plate. Two people on the left and right sides control the corrugated guardrail plate to the installation position through the handrail 8, and use the remaining anti-theft bolt holes of the corrugated guardrail plate to fix and install with bolts. After the fixed installation is stable, remove the lifting hook, and the construction is completed.
