Problems solved by technology

[0002] As a general technology, bolted connection is widely used in engineering and mechanical fields, and the maintenance degree of bolted connection fastening state is affected by external vibration and its own shear force. In severe cases, it can lead to bolt slipping and falling off. So that the overturning accident of equipment instability occurs
The installation height of the construction elevator is raised by connecting the standard sections with high-strength bolts. Since the installation height of the construction elevator is generally nearly 100 meters high, each standard section is connected by four bolts, and the tightness of the connecting bolts is inspected and monitored. It is manual monitoring, which is time-consuming and labor-intensive, difficult to put in place, and the inspection safety risk is relatively high; due to the certain vibration during the operation of the construction elevator, it directly affects the long-term maintenance of the bolt fastening standard value, and when the bolt fastening standard value is not reached , it is easy to increase the degree of bolt loosening
Once loosened, the shear force generated by the bolts and the connecting parts exceeds the limit, which will directly cause the elevator to become unstable and overturn
This kind of elevator instability and overturning accidents caused by the loosening of the standard section bolts of the elevator has occurred many times in China in recent years, and the accidents have caused heavy casualties and great economic losses.
[0003] Aiming at the deficiency of existing elevator bolt loosening monitoring technology and the insufficient intrinsic safety technology of elevators, the present invention proposes an anti-overturning safety monitoring control device and method for construction elevators

Embodiment 1

[0042] refer to Figure 1~3 As shown, the high-definition camera device 1 is installed in the cage 5 of the construction hoist through a steel bracket 103, and the high-definition camera 102 faces the high-strength bolt 2 on the standard section 3 of the construction hoist, so as to facilitate taking pictures of the high-strength bolt 2 in the working state; the high-definition camera device 1 With the construction elevator running up and down, the working status of all high-strength bolts 2 on the standard section 3 of the construction elevator can be photographed clearly.

Embodiment 2

[0044] refer to figure 2 As shown, the high-definition camera device 1 transmits the information received by the high-definition camera device 1 to the intelligent processing and display device 8 through the picture transmission device 7 for analysis and processing and then feeds it back to the screen display device. When the high-strength bolts loosen, the intelligent alarm 901 sends an alarm and the alarm display lamp 903 flickers at the same time, and the intelligent stopper 902 stops the cage 5 of the construction elevator.

Embodiment 3

[0046] refer to Figure 4 As shown, the intelligent processing and display device 8 is composed of four parts: a picture memory 801 , an intelligent processor 802 , an intelligent manager 803 and a high-definition display device 804 . The picture transmission device 7 transmits the pictures taken by the high-definition camera device 1 to the intelligent manager 803, thereby screening the pictures of the working state of the bolts taken by the high-definition camera device 1, and automatically deleting the blurred and unrecognizable pictures, so as to ensure that the pictures taken All are clear high-quality pictures; the intelligent manager 803 transmits the processed pictures to the intelligent processor 802, compares them with a group of pictures stored in the picture memory 801 under the normal working state of a group of bolts, and analyzes the difference, Transmission to the high-definition display device 804.

Abstract

The invention discloses an anti-overturning safety monitoring control device for a construction hoist. The device comprises high-definition shooting devices, high-strength bolts, a construction hoiststandard knot, a construction hoist operation room, cages, an outer fence, a picture transmission device, an intelligent processing and display device, an intelligent alarming and stopping device, anoperation table, a safety falling prevention device, an upper limiter, a lower limiter and a power switch; and the high-definition shooting devices are arranged on the inner sides of the cages of theconstruction hoist and shoot the working states of all the high-strength bolts on the construction hoist standard knot along with ascending of the cages. The anti-overturning safety monitoring controldevice for the construction hoist is reasonable in structural design, the high-definition shooting devices work up and down along with the construction hoist, the working states of the plurality of bolts can be shot by one machine, shot images are clearer, real-time monitoring is achieved, the high quality of the shot images is guaranteed, and the service cycle of the high-definition shooting devices is prolonged.
