Description

Technical Field

[0001] The utility model relates to the technical field of construction elevators, in particular to a protective structure of a construction elevator. Background Art

[0002] Construction elevators are installed with a gap between floors. If someone accidentally misses a step, they could fall, posing a safety hazard. Construction carts transporting materials are inconvenient to get on and off the elevator, and a mistaken opening or closing the door could result in someone being ejected. Summary of the Invention

[0003] The utility model provides a protective structure for a construction elevator in order to overcome the deficiencies of the prior art.

[0004] To achieve the above-mentioned purpose, a protective structure of a construction elevator is designed, comprising a car, wherein the exit of the car is provided with elevator door 1 and elevator door 2, elevator door 1 is arranged on the outside of elevator door 2, elevator door 1 comprises upper sliding door 1, flap, and cylinder 1, flap is arranged below upper sliding door 1, one end of the flap is hinged to the bottom outside of the car, protective plates are provided on both sides of the flap, cylinder 1 is transversely arranged on the side of the car, cylinder 1 is connected to both sides of the protective plate through rope 1, cylinder 1 is connected to the bottom of upper sliding door 1 by turning through pulley group through rope 2, elevator door 2 comprises upper sliding door 2 and cylinder 2, cylinder 2 is transversely arranged above the car, cylinder 2 is connected to the bottom of upper sliding door 2 by turning through fixed pulley 1 through rope 3.

[0005] The pulley group includes fixed pulley 2, fixed pulley 3, and fixed pulley 4. Fixed pulley 2 is arranged on the rear side of cylinder 1, fixed pulley 3 is arranged above fixed pulley 2, and fixed pulley 4 is arranged on the front side of fixed pulley 3 close to the side of elevator door 1.

[0006] The side wall of the car is a double-layer baffle structure including an inner baffle and an outer baffle. The cylinder 1 and the pulley assembly are arranged between the double-layer baffles. When the protective plate is folded up, it is stored between the double-layer baffles.

[0007] Both sides of the upper sliding door 1 and the upper sliding door 2 are connected to the side walls of the car through sliding rails. The sliding rails of the upper sliding door 1 are installed on the inner side of the outer baffle, and the sliding rails of the upper sliding door 2 are installed on the inner side of the inner baffle.

[0008] Compared with the prior art, the utility model has a flap that flips outwards and serves as a bottom plate to overlap the floor, making it easy for the construction trolley to enter and exit the elevator. By arranging elevator door one and elevator door two and driving them through a cylinder, the elevator door two can be opened only after the elevator door one is fully opened, thereby preventing accidents caused by misoperation of the construction trolley when the flap is opened.

DETAILED DESCRIPTION

[0013] The present invention will be further described below with reference to the accompanying drawings.

[0014] like Figure 1-Figure 3 As shown, the exit of the car 1 is provided with an elevator door 1 2 and an elevator door 2 3. The elevator door 1 2 is arranged on the outside of the elevator door 2 3. The elevator door 1 2 includes an upper sliding door 1 2-1, a flap 2-2, and a cylinder 1 2-3. The flap 2-2 is arranged below the upper sliding door 1 2-1. One end of the flap 2-2 is hinged to the outside of the bottom of the car 1. Protective plates 2-9 are provided on both sides of the flap 2-2. The cylinder 1 2-3 is arranged horizontally on the side of the car 1. The cylinder 1 2-3 is connected to both sides of the protective plate 2-9 through a rope 1 2-4. The cylinder 1 2-3 is connected to the bottom of the upper sliding door 2-1 through the turning of the pulley group through the rope 2 2-5. The elevator door 2 3 includes an upper sliding door 2 3-1 and a cylinder 2 3-2. The cylinder 2 3-2 is arranged horizontally above the car 1. The cylinder 2 3-2 is connected to the bottom of the upper sliding door 2 3-1 through the turning of the fixed pulley 1 3-4 through the rope 3 3-3.

[0015] The pulley group includes fixed pulley 2-6, fixed pulley 3 2-7, and fixed pulley 4 2-8. Fixed pulley 2-6 is arranged on the rear side of cylinder 1 2-3, fixed pulley 3 2-7 is arranged above fixed pulley 2-6, and fixed pulley 4 2-8 is arranged on the front side of fixed pulley 3 2-7 close to the side of elevator door 1 2.

[0016] The side wall 4 of the car 1 is a double-layer baffle structure including an inner baffle 4-1 and an outer baffle 4-2. The cylinder 2-3 and the pulley group are arranged between the double-layer baffles, and the protective plate 2-9 is stored between the double-layer baffles when it is folded up.

[0017] The two sides of the upper sliding door 1 2-1 and the upper sliding door 2 3-1 are connected to the side wall 4 of the car through the sliding rails 4-3. The sliding rails 4-3 of the upper sliding door 1 2-1 are installed on the inner side of the outer baffle 4-2, and the sliding rails 4-3 of the upper sliding door 2 3-1 are installed on the inner side of the inner baffle 4-1.

[0018] To open the elevator door, the cylinder 2-3 is first activated to move forward. Rope 2-4 lowers flap 2-2. Simultaneously, rope 2-5, passing through the pulley block, pulls upward along rail 4-3, pulling upper sliding door 2-1, opening elevator door 2. Cylinder 3-2 then drives rope 3-3 backward, opening elevator door 2-3. This allows personnel and construction vehicles to enter and exit the elevator. To close the elevator door, cylinder 3-2 closes door 2-3. Cylinder 2-3 then moves backward, retracting flap 2-2, lowering upper sliding door 2-1, and closing elevator door 2. Door 2 can be opened only after door 2 is fully open, preventing accidents caused by construction vehicles operating while flap 2-2 is open. When flap 2-2 is opened, it serves as a step, and protective plate 2-9 acts as a handrail, preventing personnel from falling through the gap between the elevator car 1 and the floor, or from the sides, ensuring safer entry and exit for personnel and vehicles.

[0019] Cylinder 1 (2-3) can be a slider-type cylinder to facilitate connecting rope 1 (2-4) and rope 2 (2-5) from two directions. Cylinder 2 (3-3) can be a linear cylinder. The sidewall 4 of car 1 features a double-layer structure to enhance protection. A construction vehicle colliding with the sidewall 4 of the construction elevator is less likely to damage both layers. The operating mechanism of door 1 (2) is housed between inner and outer baffles (4-1, 4-2), while the operating mechanism of door 2 (3) can be located within car 1, preventing interference between the operating mechanisms of the two doors.
