Description

Technical Field

[0001] The present invention is a method for preventing collision of a construction elevator car, belonging to the field of construction. Background Art

[0002] Construction elevators are mainly used in various high-rise and super high-rise buildings in cities. They are construction machinery for carrying people and goods that are often used in construction. Since construction elevators are used frequently, ensuring the safe use of elevators is particularly important. Especially for the cage door on the side facing the air during operation, the connection method between the cage door and the car is that there are hanging door rollers above the car door, and they are hung on the car door guide rail through the hanging door rollers, resulting in poor anti-collision ability and often having potential safety hazards of falling people and falling objects. In recent years, electric transport vehicles have become popular. When transporting labor carts (push carts, electric vehicles, etc.) through the elevator car, it is easy to occur the phenomenon that the vehicle runs out of control and collides with the elevator car door, which may lead to potential safety hazards during construction and even cause accidents. Therefore, it is necessary to take measures to solve the problems that the construction vehicle often slides when parked in the elevator, resulting in the construction vehicle hitting the elevator door, and the construction vehicle falling from the elevator, thus causing accidents.

Description of the Drawings

[0021] By reading the detailed description of the non-restrictive embodiments with reference to the following drawings, other features, purposes, and advantages of the present invention will become more obvious:

[0022] Figure 1 It is a schematic structural diagram of a method for preventing collision of a construction elevator car of the present invention;

[0023] Figure 2 It is a schematic structural diagram of a method for preventing collision of a construction elevator car of the present invention.

[0024] In the figure: Specific implementation manner

[0025] To make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0026] Please refer to Figure 1 and Figure 2 , the present invention provides a technical solution for preventing collision of a construction elevator car: including:

[0027] The tread is a longitudinally arranged multi-faceted conveyor belt, designed for circular motion to adapt to the multi-wheel tires of the construction vehicle 2 to ensure stable transmission. In one embodiment, the tread adopts an existing escalator track. Among them, the tread is arranged in the adjustment area B inside the elevator car 1 to facilitate the rear wheels of the construction vehicle 2 to be engaged with the adjustment area B. The tread is driven by a motor to circulate, and the motor is controlled by a control panel 5 inside the elevator car 1 to open and close. After the construction vehicle 2 enters the elevator car 1, the control panel 5 turns on the motor, and the tread drives the construction vehicle 2 into the inner side of the elevator car 1.

[0028] The anti-collision component 3 includes a base 31, a fender 32, and a footrest 33. The base 31 is fixed on the side wall of the elevator car 1, located at the lower half of the elevator car 1; the fender 32 is hinged on the base 31 and is used to block the door inside the elevator car 1; the footrest 33 is hinged at the end of the fender 32 and can support on the ground of the elevator car 1 after being unfolded to enhance stability. Further, the hinged end of the footrest 33 and the fender 32 is semi-circular, and the fender 32 is correspondingly provided with a semi-circular hinge seat. In this way, when the footrest 33 is stressed, it can prevent the footrest 33 from rotating excessively, resulting in the fender 32 falling to the ground. Preferably, the hinge point between the base 31 and the fender 32 has damping, so that when the fender 32 stands up naturally, it will not rotate from the base 31 and needs to be manually turned.

[0029] The infrared switch 4 is arranged behind the anti-collision component 3 and is used to detect whether the construction vehicle 2 has crossed the front area 1 to assist manual judgment whether the fender 32 will collide with the construction vehicle 2 after falling.

[0030] The signal lamp 6 is strip-shaped and is arranged in the front area 1 inside the elevator car 1 for easy observation by construction workers. It is electrically connected to the infrared switch 4. In one embodiment, when the infrared switch 4 detects that the construction vehicle 2 has crossed the front area 1, the green light will be lit, and the fender 32 will be manually lowered to block the construction vehicle 2.

[0031] A method for preventing collision of a construction elevator car 1 includes the following steps:

[0032] Step 1: Divide the inside of the elevator car 1 into 3 placement areas, including the front area 1, the adjustment area B, and the rear area C; among them, the front area 1 is horizontally placed inside the door of the elevator car 1; the adjustment area B and the rear area C are vertically placed inside the door of the elevator car 1; position the 2 front wheels of the construction vehicle 2 in the front area 1, one rear wheel in the rear area C, and the other rear wheel in the adjustment area B; further, the front area 1, the adjustment area B, and the rear area C are all circled by different colored marking lines.

[0033] Step 2: Replace the tires of the construction vehicle 2 with multi-wheel treaded tires, and the tread path is arranged in the adjustment area B, so that the rear wheel positioned in the adjustment area B is engaged with the adjustment area B;

[0034] Step 3: Install a control panel 5 inside the elevator car 1 for opening and closing the motor; based on Step 1, when the construction vehicle 2 enters the elevator car 1, the motor is turned on by the control panel 5, and the tread path drives the construction vehicle 2 into the inner side of the elevator car 1;

[0035] Step 4: Lower the anti-collision component 3 to block the construction vehicle 2 according to the indication of the signal lamp 6.

[0036] Embodiment 1

[0037] Equipment preparation:

[0038] Tread path: Adopt a vertically arranged multi-sided conveyor belt, equipped with a motor drive system.

[0039] Anti-collision component 3: Includes a base 31, an anti-collision bar 32, and a footrest 33. The base 31 is fixed on the side wall of the elevator car 1, the anti-collision bar 32 is hinged on the base 31, and the footrest 33 is hinged at the end of the anti-collision bar 32.

[0040] Infrared switch 4: Installed behind the anti-collision component 3 for detecting whether the construction vehicle 2 exceeds the front area 1.

[0041] Signal lamp 6: Designed in a strip shape, installed at the position of the front area 1, and electrically connected to the infrared switch 4.

[0042] Control panel 5: Set at a convenient operation position inside the elevator car 1 for opening and closing the motor.

[0043] Construction vehicle 2 preparation:

[0044] Replace the tires of the construction vehicle 2 with multi-wheel treaded tires to ensure that the contact surface between the tires and the tread path is matched and can be engaged.

[0045] III. Implementation steps

[0046] Area division inside the elevator car 1:

[0047] Divide the inside of the elevator car 1 into the front area 1, the adjustment area B, and the rear area C.

[0048] The front area 1 is horizontally placed inside the door of the elevator car 1, and the width of the front area 1 is close to the width of the elevator car 1.

[0049] The adjustment area B and the rear area C are vertically placed inside the door of the elevator car 1. The width of the adjustment area B is greater than the width of the rear wheels of the construction vehicle 2, and the width of the rear area C accounts for about half of the width of the elevator car 1.

[0050] Start the track conveyor system:

[0051] The construction vehicle 2 enters the elevator car 1. After the rear wheels of the construction vehicle 2 fall on the track, the operator turns on the motor through the control panel 5.

[0052] The track starts to move in a cycle, driving the construction vehicle 2 to slowly move inward to the elevator car 1 until the front wheels of the construction vehicle 2 enter the front area 1.

[0053] Operate the anti-collision component 3:

[0054] After the front wheels of the construction vehicle 2 enter the front area 1, the infrared switch 4 detects the position of the construction vehicle 2.

[0055] If the construction vehicle 2 does not exceed the front area 1, the signal lamp 6 lights up green, indicating that the anti-collision component 3 can be lowered.

[0056] The operator manually lowers the anti-collision component 3 so that the anti-collision bar 32 and the footrest 33 block the construction vehicle 2 to prevent the construction vehicle 2 from colliding with the car wall during the movement inside the elevator car 1.
