Description

TECHNICAL FIELD

[0001] The present application relates to the field of construction safety auxiliary tools, in particular to an intelligent alarm anti-falling safety rope device. BACKGROUND

[0002] Construction safety is the cornerstone of the construction industry and the premise of all work of construction enterprises. Safety production must be put into practice, which puts forward requirements for construction personnel, construction management departments and safety production equipment. First of all, the construction personnel themselves, at present, part of the construction personnel's safety awareness is still not enough, and they often operate non-standardly for the purpose of convenience in the construction process, and do not pay attention to their own life safety, which also hides quality hazards for civil construction projects. Secondly, for construction personnel working in dangerous conditions such as high altitude and outside, their safety needs more protection from construction units. Insufficient safety measures, unstable safety equipment, insufficient safety awareness, and non-implementation of safety education are important reasons for the violation of construction personnel's operation. Of course, safety production equipment is the most closely watched and valued. The existing safety rope, anti-falling device and other safety protection equipment have defects. Although they can guarantee the safety of the operator to a certain extent, they cannot solve the problems of real-time warning and monitoring in the production and construction process, timely rescue and signal transmission after an accident. Therefore, attention must be paid to safety production and the standard operation of construction personnel must be ensured, which also provides a practical guarantee for improving the economic and social benefits of civil construction. Construction safety protection is a long-term work with high technical requirements. Construction personnel, construction management departments, safety production equipment and even relevant regulatory departments must work together to ensure the quality of the project and the safety of people's lives and property.

[0003] In the construction safety protection, safety rope and anti-falling device are usually used to protect the safety of construction personnel. The commonly used matching facilities have defects such as complicated structure, incomplete design, single function, low fine level and inconvenient management. Common anti-falling devices include wooden tankway type anti-falling device, metal tankway type anti-falling device and steel wire rope braking type anti-falling device. Among them, the braking force of the wooden tankway type anti-falling device is difficult to meet the design requirements, and the maintenance workload is large, so its use is limited. The metal tankway type anti-falling device uses steel rail tankway as the supporting element of the anti-falling device, and brakes the falling cage on the steel rail tankway. In addition to the difficulty in meeting the design requirements of the braking force, the installation of the facility is also inconvenient, and the construction space is occupied. The steel wire rope braking type anti-falling device also has the shortcomings of being unable to transmit signals and real-time warning in time. SUMMARY

[0006] (2) Technical scheme

[0007] In view of the above technical problems, the application is solved by the following technical scheme:

[0008] An intelligent alarm anti-falling safety rope device includes a safety belt part, the safety belt includes a polyethylene safety belt, and a transverse constraint is formed at the chest, waist, and hip, and each side of the body has a safety belt, which is crossed and constrained behind the back after passing over the shoulder, and a D-shaped ring is arranged at the crossing, and the safety belt is extended downward as a leg binding belt, and the safety belts on both sides, the chest, the waist, and the leg binding part are all provided with length adjusting buckles, and a signal transmission device is arranged at the front shoulder part of the safety belt, and circuit closing switches are arranged at the waist and the two leg binding parts and are connected in series with the signal transmission device.

[0009] As a preferred, a specially modified sliding rheostat, a signal transmitter, and a bulb are connected in series in the circuit, and when the three switches are closed, a path is formed and a signal that the safety belt is correctly worn is sent to the main control room.

[0010] The application can ensure that the correct wearing signal of the safety belt is transmitted to the main control room in time after the construction personnel correctly wear the safety belt, and the specially designed rheostat and signal transmitter are used to monitor the correct wearing of the construction personnel in real time.

[0011] An intelligent alarm anti-falling safety rope device includes an anti-falling device main part, four metal claws are arranged around the upper part of the anti-falling device main part, one end of the metal claw is hinged to the anti-falling device body, the other end is connected to the anti-falling device body by means of a spring and a metal rod, a flat opening with a suitable size is formed at the end of the metal rod connected with the claw, so that the claw can move freely with the rod when the claw is activated, a metal ring is arranged around the outside of the claw to limit the displacement of the claw, four single-dimensional movable metal rods are arranged around the inside of the metal ring, the metal rods have good conductivity and are assisted by springs to reset, the lower part of the anti-falling device main part is sleeved into the shell of the device, and the displacement of the anti-falling device is limited to ensure that the safety rope can be freely rotated with the anti-falling device main part when the safety rope is retracted or released.

[0012] When the safety rope is slowly pulled out, the anti-falling device main part rotates freely, and the construction proceeds normally; when the safety rope is quickly pulled out due to an accident, the rope drives the anti-falling device main part to rotate quickly, the metal claws on the upper part of the main body immediately expand outward due to the centrifugal force, the displacement of the metal claws is limited by the metal ring around the periphery, the anti-falling device main part is controlled to stop rotating, the sliding of the safety rope is terminated, and the safety of the construction personnel is ensured.

[0013] The application can real-time alert the construction personnel to operate safely in a small range, and timely limit the abnormal displacement of the safety rope in the construction process, so as to avoid safety accidents caused by illegal operation.

[0015] As preferred, the signal alarm device is further provided with an alert lamp and an alarm, which are used to real-time remind the construction personnel to pay attention to safe operation. When the construction personnel moves quickly, the upper pawl of the fall arrestor will be in brief contact with the movable metal rod in the inner ring of the metal ring. The metal rod has good conductivity, and the circuit is connected instantaneously, so that the alert lamp flashes briefly and the alarm beeps briefly.

[0016] In the application, the alert lamp and the alarm are connected in series in the circuit, so that the fall arrestor can real-time remind the construction personnel to slow down and reduce the range, and the effect of safe operation is achieved.

[0017] As preferred, the signal alarm device is provided with a photoresistor and a signal transmitter, which are connected in series with the alert lamp and the alarm as described above, and the photoresistor is connected in parallel with the alert lamp. When the construction personnel has an accident, the safety rope is quickly pulled out, the main body of the fall arrestor is rotated, the pawl is expanded outward, and the displacement of the pawl is limited by the metal rod, so that the pawl is immediately locked. The locking process of the pawl is not brief, so that the circuit connected by the metal rod is kept open for a long time, the alarm beeps for a long time, the alert lamp is on for a long time, the resistance value of the photoresistor decreases rapidly, and the signal transmitter immediately sends an accident alarm signal to the main control room of the construction unit.

[0018] In the application, the photoresistor and the signal transmitter are installed in the signal alarm device, so that the remote monitoring of the construction management department is realized, and the rescue work can be arranged in the first time.

[0019] As preferred, the lower part of the shell of the intelligent alarm fall arrest safety rope device is detachable, and a hidden shaft is arranged at the bottom of the main body of the fall arrestor, so that the safety rope can be recovered in the reverse direction. Due to the arc design of the pawl of the fall arrestor and the inner side of the metal ring, the safety rope will not be locked when it is recovered in the reverse direction.

[0020] In the application, the arc design of the pawl of the fall arrestor ensures that the safety rope will not be locked in the reverse direction, and the safety rope can be recovered conveniently.

[0021] As preferred, a spring-pressed rope fixing rod is arranged in the main shaft of the fall arrestor. After the spring-pressed section is pressed downward, the rope sleeve is sleeved, and after the spring-pressed section is released, the rope sleeve is limited in the main shaft of the fall arrestor.

[0022] In the application, the spring-pressed rope fixing rod arranged in the main shaft of the fall arrestor makes the replacement of the safety rope convenient and fast, and the rope sleeve is fixed, so that the rope end is not easy to slide.
