Description

Technical Field

[0001] The utility model relates to the technical field of construction elevators, in particular to an anti-falling safety detection device for elevators. Background Art

[0002] A construction elevator is composed of a car, a drive mechanism, a standard section, a wall attachment, a chassis, a fence, an electrical system and other parts. It is a manned and cargo-carrying construction machinery frequently used in construction. Due to its unique box structure, it is both comfortable and safe to ride. Construction elevators are usually used in conjunction with tower cranes on construction sites, with a general load capacity of 0.3-3.6 tons. During assembly and use, they must be equipped with anti-fall safety detection devices to improve the safe use of the elevator.

[0003] With respect to the above-mentioned related technologies, the inventor believes that the following defects exist: most existing elevators are driven by a driving device, and the elevator is driven up and down by multiple ropes fixed on the output shaft of the driving device. During this process, if one of the ropes breaks, the load on the remaining ropes will increase, thereby increasing the probability of the remaining ropes breaking, thereby increasing the probability of accidents. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a lift anti-falling safety detection device.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: an elevator anti-fall safety detection device, including a base, two guide rails are symmetrically arranged on the upper surface of the base, a car is slidably arranged on the side walls of the two guide rails close to each other, a support plate is fixedly arranged on the upper surfaces of the two guide rails, a plurality of suspension ropes are arranged on the upper surface of the car, a driving device is fixedly arranged on the upper surface of the support plate, the other ends of the plurality of suspension ropes pass through the support plate and are interconnected with the driving device, and a monitoring device is arranged on the car.

[0006] By adopting the above technical solution, when the staff needs to use the elevator, the staff needs to start the driving device, so that the suspension rope moves up and down under the action of the driving device, so that the car slides up and down under the action of the suspension rope. In this process, when one of the suspension ropes breaks, the monitoring device detects that the suspension rope has broken. Subsequently, the staff is warned. At this time, the staff repairs the suspension rope, thereby reducing the probability of the remaining suspension ropes breaking when one of the suspension ropes breaks, thereby reducing the probability of safety accidents.

[0007] Furthermore, a plurality of slide grooves are arranged in an array on the upper surface of the car, and a limit groove is arranged on the inner wall of the slide groove. The monitoring device includes a plurality of slide rods slidably arranged in the plurality of slide grooves, a plurality of limit blocks slidably arranged in the plurality of limit grooves, and a plurality of control buttons fixedly arranged on the bottom walls of the plurality of slide grooves, a plurality of the limit blocks are respectively fixed to the adjacent slide rods, and a plurality of the ends of the suspension ropes away from the driving device are respectively fixed to the upper surfaces of the plurality of slide rods.

[0008] By adopting the above technical solution, when the elevator is working normally, the slide bar slides upward under the action of the suspension rope. During this process, the limit block limits the slide bar, so that the upper surface of the slide bar is always flush with the upper surface of the car. At this time, if one of the suspension ropes breaks, the slide bar interacts downward under the action of gravity, and then the limit block slides downward under the action of the slide bar, so that the slide bar gradually approaches and finally presses against the control button, so that the control button triggers the alarm device to alarm.

[0009] Furthermore, first springs are fixedly disposed on the bottom surfaces of the plurality of limit blocks, and the other ends of the plurality of first springs are fixedly disposed on the inner bottom wall of the limit groove.

[0010] By adopting the above technical solution, when one of the suspension ropes breaks, the limit block interacts downward under the action of the first spring. During this process, the difficulty of the slide bar sliding downward is reduced, thereby reducing the probability of the slide bar getting stuck.

[0011] Furthermore, a blocking plate is slidably arranged on the inner wall of the slide groove, a second spring is fixedly arranged on the bottom surface of the blocking plate, and the other end of the second spring is fixedly arranged on the inner bottom wall of the slide groove.

[0012] By adopting the above technical solution, when the sliding rod slides downward, the bottom surface of the sliding rod abuts against the upper surface of the blocking plate, and then the blocking plate slides downward under the action of the sliding rod, so that the group baffle plate triggers the control button. During this process, the second spring buffers the blocking plate, thereby reducing the probability of the blocking plate triggering the control button and causing damage to the control button.

[0013] Furthermore, an alarm device is fixedly mounted on the inner top wall of the car, and the plurality of control buttons are electrically connected to the alarm device.

[0014] By adopting the above technical solution, the alarm device warns the people in the car and those who are about to use the car, thereby reducing the probability that someone will still use the car when one of the suspension ropes breaks, thereby reducing the probability of causing casualties.

[0015] Furthermore, a hanging ring is fixedly provided on the upper surface of each of the plurality of sliding rods, a buckle is fixedly provided on one end of each of the plurality of suspension ropes away from the driving device, and the plurality of buckles cooperate with the plurality of hanging rings respectively.

[0016] By adopting the above technical solution, the buckle and the hanging ring improve the connection strength between the suspension rope and the slide bar. In addition, it also reduces the difficulty of the staff in repairing the suspension rope.

[0017] In summary, the utility model has the following beneficial effects:

[0018] 1. In this application, when the staff needs to use the elevator, the staff needs to start the driving device, so that the ropes move up and down under the action of the driving device, so that the car slides up and down under the action of the ropes. During this process, when one of the ropes breaks, the monitoring device detects that the rope has broken. Then, the staff is warned. At this time, the staff repairs the ropes, thereby reducing the probability of the remaining ropes breaking when one of the ropes breaks, thereby reducing the probability of a safety accident.

[0019] 2. In this application, when the elevator is working normally, the slide bar slides upward under the action of the suspension rope. During this process, the limit block limits the slide bar, so that the upper surface of the slide bar is always flush with the upper surface of the car. At this time, if one of the suspension ropes breaks, the slide bar interacts downward under the action of gravity, and then the limit block slides downward under the action of the slide bar, so that the slide bar gradually approaches and finally presses against the control button, so that the control button triggers the alarm device to alarm;

[0020] 3. In the present application, when one of the suspension ropes breaks, the limit block interacts downward under the action of the first spring. During this process, the difficulty of the slide bar sliding downward is reduced, thereby reducing the probability of the slide bar getting stuck. BRIEF DESCRIPTION OF THE DRAWINGS
