Description

Technical Field

[0001] The utility model relates to a guardrail, in particular to a flip-foldable cage top guardrail, which belongs to the technical field of construction hoisting and transporting machinery. Background Art

[0002] The cage top guardrail of a construction elevator is an indispensable safety protection device for operators to operate on the cage top during the use of the construction elevator, especially during maintenance work.

[0003] At present, most of the cage top guardrails of construction elevators on the market adopt bolt connections between sheet units. Then, the whole cage top guardrail is inserted into the corresponding position on the cage top of the hoist, and then bolted and locked. The installation is relatively cumbersome, as Figure 1 shown.

[0004] During the transportation process of the whole machine shipment and the disassembly, assembly and transfer, if the cage top guardrail is not disassembled, the overall height of the hoist cage will exceed the limit, which is restricted by relevant transportation regulations. Therefore, the cage top guardrail must be disassembled, which brings certain troubles to the disassembly and assembly operations of the construction elevator, and at the same time, it is easy to cause mistakes such as missing shipment and missing parts, increasing the installation cost.

[0005] Therefore, a flip-foldable cage top guardrail has been developed, which avoids the trouble of disassembling the cage top guardrail from the cage structure during the shipment and the disassembly, assembly and transportation of the construction elevator, and greatly improves the disassembly and assembly efficiency. Content of the Utility Model

[0006] The purpose of the utility model is to overcome the above-mentioned deficiencies existing in the prior art, and to provide a flip-foldable cage top guardrail with reasonable structural design, safety and reliability, and convenient installation and disassembly.

[0007] The technical solution adopted by the utility model to solve the above problems is: the flip-foldable cage top guardrail includes a left sheet unit, a rear sheet unit, a right sheet unit and a front sheet unit, and is characterized in that: it further includes connecting ear plates, pin shaft one, flip connecting ear plates, hinge ear plate one, pin shaft two and hinge ear plate two. The left sheet unit is hinged to the front sheet unit and the rear sheet unit by pin shaft two. A hinge ear plate one is welded on the left sheet unit, and hinge ear plate two is welded on the front sheet unit and the rear sheet unit; the left sheet unit and the right sheet unit are hinged to the cage top of the hoist by pin shaft one. Flip connecting ear plates are welded at the bottom positions of the left sheet unit and the right sheet unit, and connecting ear plates are welded at the corresponding positions on the cage top of the hoist.

[0008] As a preference, the front sheet unit and the rear sheet unit of the utility model can respectively rotate around the pin shaft two for folding.

[0009] As a preference, the left sheet unit and the right sheet unit of the utility model are respectively flipped through the pin shaft one.

[0010] Preferably, the front sheet unit, the rear sheet unit and the right sheet unit of the present utility model are fastened and connected by bolts.

[0011] Compared with the prior art, the present utility model has the following advantages and effects: The overall structure is reasonably designed, safe and reliable. The front sheet unit and the rear sheet unit can be respectively rotated around the pin shaft II for folding; the left sheet unit and the right sheet unit are respectively flipped through the pin shaft I, and there is no need to disassemble from the cage structure during transportation, which improves the assembly and disassembly efficiency and meets the use requirements.

[0020] The present utility model will be further described in detail below with reference to the drawings and through embodiments. The following embodiments are explanations of the present utility model, and the present utility model is not limited to the following embodiments.

[0021] Embodiment

[0022] See Figures 3 to 7, the flip-folded cage top guardrail in this embodiment mainly includes a left sheet unit 1, a rear sheet unit 2, a right sheet unit 3, and a front sheet unit 4. The left sheet unit 1 is hinged to the front sheet unit 4 and the rear sheet unit 2 by a second pin 9. An ear plate one 8 is welded on the left sheet unit 1, and ear plates two 10 are welded on the front sheet unit 4 and the rear sheet unit 2; the front sheet unit 4 and the rear sheet unit 2 can rotate around the second pin 9 respectively for folding, as shown in Figure 6 horizontal folding F1 in

[0023] In this embodiment, the front sheet unit 4 and the rear sheet unit 2 are fixedly connected to the right sheet unit 3 by bolts.

[0024] In this embodiment, the left sheet unit 1 and the right sheet unit 3 are hinged to the cage top of the suspension cage by a first pin 6. At the bottom positions of the left sheet unit 1 and the right sheet unit 3, flip connection ear plates 7 are welded, and connection ear plates 5 are welded at the corresponding positions on the cage top; the left sheet unit 1 and the right sheet unit 3 are flipped respectively through the pin 6, as shown in Figure 7 vertical folding F2 in
