Description

Technical Field

[0002] At present, there are two situations for the anti-collision measures of traditional construction elevators: No corresponding anti-collision measures are adopted, and hard steel pipes are welded and fixed to the construction elevator cage. If relevant anti-collision measures are not adopted, the following problems will occur: Cage instability: At present, the transportation equipment for transporting materials in the project is mostly bucket trucks and electric dump trucks. If the operator makes a mistake in the process of transporting materials, it will cause the material transportation equipment to move forward or backward, which is easy to cause the cage to become unstable, thus causing safety accidents;

[0003] If the hard steel pipe is welded to the cage of the construction elevator, the following problems will occur: (1) Inconvenient operation: The welding of the hard steel pipe to the cage limits the range of movement of the steel pipe, causing obstacles when transporting large materials and affecting the normal operation of the construction elevator;

[0004] (2) Non-standardization affects the appearance: Steel pipe welding often uses on-site cost materials for welding and fixing, which has a very poor appearance;

[0005] (3) Welding with the ladder cage makes it inconvenient to dismantle and replace: When the steel pipe is welded to the ladder cage, if the steel pipe needs to be replaced due to deformation, contamination, etc., the steel pipe must be cut and re-welded, which requires high skills of the operator.

[0059] In an embodiment of the present invention, the buffer column 402 is made of rubber material, so that when the protective plate 401 contacts the ground, it can buffer the force acting on the protective plate 401 to a certain extent. The piston column 404 is slidably connected to the threaded column 405 to perform piston movement. The outer spring 407 and the buffer column 402 perform buffering synchronously. The piston column 404 and the threaded column 405 play a guiding role in the buffering process of the spring 407 to prevent the spring 407 from deforming and affecting the buffering effect. An adjusting plate 406 is fixed to the upper end of the spring 407, and the lower end of the spring 407 is fixedly connected to the piston column 404. The adjusting plate 406 is threadedly matched with the threaded column 405. 406 is adjusted in the position of the threaded column 405 to adjust the tightness of the spring 407, thereby adjusting the buffering force of the spring 407, which can be adjusted according to the load in the construction elevator cage 200. A fixed plate 408 is provided at the upper end of the threaded column 405, and buffer structures are provided at the four corners of the upper surface of the fixed plate 408. The size of the buffer structure below the fixed plate 408 is 1.5-2 times that of the buffer structure provided on the upper surface of the fixed plate 408. A small-sized buffer structure is provided on the fixed plate 408, which increases the buffering force of the protective component 400 and improves the protective performance. When the construction elevator falls rapidly, it can provide certain protection and improve safety.

[0060] In an embodiment of the present invention, an electric hoist 101 is provided at the upper end of the interior of the elevator shaft 100, and a hook connection is provided between the electric hoist 101 and the construction elevator cage 200, so that the construction elevator cage 200 is hoisted in the elevator shaft 100, and side panels 201 and mounting plates 203 are welded on both sides of the upper end of the construction elevator cage 200, and pulleys 202 are connected to the internal screws of the side panels 201, and guide wheels 204 are provided on the inner side of the mounting plate 203, and the guide wheels 204 penetrate the construction elevator cage 200 and are slidably connected to the elevator shaft 100, and the guide wheels 204 move on the inner surface of the elevator shaft 100 frame through the pulleys 202 on both sides of the elevator shaft 100 frame, and the electric hoist 101 controls the construction elevator cage 200 to move synchronously when lifting and lowering, thereby avoiding position displacement of the construction elevator cage 200.

[0061] In the embodiment of the present invention, two hanging rings 302 are installed on the inner side of the construction elevator cage 200, and the hanging ring 302 is bolted to the construction elevator cage 200 through the mounting block 301. The hook portion of the movable hook 303 passes through the hanging ring 302, one end of the anti-slip sheet 304 is screwed to the movable hook 303, and the other end is arranged on the inner side of the hook portion of the movable hook 303, and a connecting ring 305 is arranged between the rear end of the sliding hook and the wire rope 306, and the connecting ring 305 is screwed to the movable hook 303, and the connecting ring 305 is a closed ring design, and the wire rope 306 passes through the connecting ring 305, and the wire rope 306 is closed, and is pre-set according to the width of the construction elevator cage 200. First, during the production process, a closed structure is formed directly with the connecting ring 305. When in use, two hanging rings 302 are set on both sides of the construction elevator cage 200, and the wire rope 306 is hooked on the hanging ring 302 through the movable hook 303. The anti-slip piece 304 on the inner side of the movable hook 303 is used to prevent the movable hook 303 from being unhooked due to shaking. When material transportation equipment such as a bucket truck for transporting materials enters the construction elevator cage 200, the operator only needs to hang the movable hook 303 in the hanging ring 302 reserved on the other side of the elevator cage, and block the wire rope 306 between the elevator door and the bucket truck, so as to prevent the transportation equipment from becoming unstable and hitting the elevator cage door due to elevator shaking or operator error.

[0062] In an embodiment of the present invention, the braking module 501 is used to brake the elevator when an emergency situation is detected;

[0063] The monitoring module 502 is used to monitor the elevator operation status in real time, including speed and position information;

[0064] The alarm module 503 is used to send out sound and light alarms during emergency braking or collision avoidance to alert passengers and operators;

[0065] The communication module 504 is used to realize information transmission between the electric hoist 101, the anti-collision component 300 and the protection component 400, including wired connection and wireless connection.

[0066] In the embodiment of the present invention, the braking module 501 further includes receiving the elevator operation status signal of the monitoring module 502;

[0067] Determine whether the elevator is in an emergency state, that is, whether the elevator is hit, the initial position of the bucket car in the elevator is offset, etc. If so, control the electric hoist 101 to brake through the anti-collision control unit 5023;

[0068] If the elevator is in a non-emergency state, continue to receive elevator operation data from the monitoring module 502;

[0069] When the monitoring module 502 detects a collision, the elevator is controlled to slow down or stop.

[0070] In the embodiment of the present invention, the monitoring module 502 includes an information collection unit 5021, an anti-collision judgment unit and an anti-collision control unit 5023;

[0071] The information collection unit 5021 uses a tension sensor, a pressure sensor and a GPS locator to collect information about the tension of the steel wire rope 306, the load of the construction elevator cage 200 and the position of the transport bucket truck in the construction elevator cage 200;

[0072] The impact judgment unit 5022 performs impact judgment on the data collected from the information collection unit 5021, and compares the real-time data with the threshold value by presetting the data threshold value in the brake module 501. When the threshold value is exceeded, it is a collision state. If the data exceeds the threshold value too much, such as when the threshold tension value is 5N and the real-time data is 8N, it means that the construction elevator cage 200 is subjected to a strong impact, causing the wire rope 306 to be in a tight state, then the brake module 501 is used to control the electric hoist 101 for emergency braking. If the control is out of control, the impact force of the landing is monitored by the bottom protection component 400 to reduce the damage. The spring 407 uses a coil spring 407, a butterfly spring 407, an air spring 407 and other springs 407 with good buffering force to buffer the impact force of the elevator descent;

[0073] The anti-collision control unit 5023 is used to send a signal to the anti-collision controller when the collision judgment unit 5022 determines that there is a collision. After receiving the signal, the anti-collision controller will immediately analyze and process it, determine the location of the collision, and issue a warning signal according to the preset safety logic.

[0079] S4, the staff in the construction elevator cage 200 will handle it in time until the monitored data returns to normal and the alarm module 503 stops the alarm. If it is in the alarm state for a long time, for example, when the alarm duration preset in the braking module 501 reaches 3 minutes and the alarm has not stopped, the external staff will go to the construction elevator cage 200 where the collision occurred according to the location information and handle the construction elevator cage 200.
