Description

Technical Field

[0001] This utility model relates to the field of construction hoist technology, and in particular to a construction hoist cage. Background Technology

[0002] Traditional construction hoist cages consist of a cage body, cage doors at both ends of the cage body, and a gantry crane that drives the cage doors to open and close. The cage body includes a frame, a top plate on top of the frame, and side plates on both sides of the frame. Traditional construction hoist cages have the following defects: Rainwater intrusion: There is no protective structure at the top, and rainwater can easily splash into the cage as it rises and falls, affecting operational safety; Door derailment risk: The cage doors are exposed to the outside and are prone to derailment and jamming due to external impacts; Exposed chain hazard: The gantry crane drive chain is exposed, posing a risk of injury to personnel or trapping debris. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a construction hoist cage that reduces rainwater splashing into the cage, reduces the risk of cage door derailment, and reduces the safety risk of cage door chain.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a construction hoist cage, including a cage body, a cage door, and a cage door operator for driving the opening and closing of the cage door. The top of the cage body is provided with inclined protective plates around its perimeter. The cage door is located inside the corresponding protective plates, and the chain of the cage door operator is located inside the protective plates. The principle of this utility model is as follows: the inclined protective plates around the top allow rainwater to be thrown outwards along the slope, reducing rainwater splashing into the cage; the inclined protective plates form a buffer slope, decomposing the impact force of falling objects into a horizontal component, reducing direct damage to the top plate; the cage door is located inside the protective plates, which act as a physical barrier to block external impacts and prevent the cage door from derailing; the chain is located inside the protective plates, reducing the risk of exposure.

[0005] As an improvement, the cage body includes a frame, a top plate on top of the frame, columns at the entrance of the frame, and side plates on both sides of the frame. A bending plate is provided between the tops of two adjacent columns, and the bending plate is connected to the top plate.

[0006] As an improvement, the guard plate includes a first guard plate located at both ends of the cage and a second guard plate located on both sides of the cage, the cage door is located inside the first guard plate, and the chain of the cage door motor is located inside the second guard plate.

[0007] As an improvement, an obstacle hole is formed between the first guard plate and the bending plate to allow the cage door to pass through. The two ends of the first guard plate are respectively connected to the columns on both sides, and the lower end of the second guard plate is connected to the top plate.

[0008] As an improvement, the first guard plate is Z-shaped, and the second guard plate includes a second inclined plate, a first bent portion located at the upper end of the second inclined plate and bent inward, and a second bent portion located at the lower end of the second inclined plate and bent inward, wherein the second bent portion is connected to the top plate.

[0009] As an improvement, the chain of the hoisting cage is located on the inner side below the second guard plate, the chain of the hoisting cage is located behind the column, and the chain of the hoisting cage is located on the outer side of the side plate.

[0010] As an improvement, an inspection window is provided on the top plate, and a ladder is provided on the inner side of the cage body corresponding to the inspection window.

[0011] The beneficial effects of this utility model compared with the prior art are:

[0012] The top is equipped with inclined guardrails around the perimeter, which throw rainwater outwards along the slope, reducing rainwater splashing into the cage. The inclined guardrails form a buffer slope, which decomposes the impact force of falling objects into a horizontal component, reducing direct damage to the top plate. The cage door is located inside the guardrails, which act as a physical barrier to block external impacts and prevent the cage door from derailing. The chain is located inside the guardrails, reducing the risk of exposure. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] like Figures 1 to 5As shown, a construction hoist cage includes a cage body, a cage door, and a cage door operator for opening and closing the cage door. The cage door operator includes a motor, an output shaft, and a chain 7. The motor drives the chain 7 through the output shaft, and the chain 7 drives the cage door to open and close. The cage body includes a frame, a top plate 4 on top of the frame, columns 6 on both sides of the frame door, and side plates 3 on both sides of the frame. A bent plate 7 is provided between the tops of two adjacent columns 6, and the bent plate 7 is connected to the top plate 4. An inspection window is provided on the top plate 4, and a ladder is provided on the inner side of the cage body corresponding to the inspection window. The top of the cage body is provided with inclined protective plates around its perimeter. The protective plates include first protective plates 1 located at both ends of the cage and second protective plates 2 located on both sides of the cage. The cage door is located inside the first protective plate 1. An obstacle hole is formed between the first protective plate 1 and the bending plate 7 for the cage door 8 to pass through.
