Embodiment 1

[0043] Embodiment one: if figure 1 As shown, a hanging basket safety lock detection system includes a first crossbeam 1 and a second crossbeam 2 arranged up and down, a vertical beam 3 connecting the first crossbeam 1 and the second crossbeam 1, a shaft connected to the vertical beam 3 and subjected to The platform 4 that can be rotated between the first crossbeam 1 and the second crossbeam 3 at its axis joint when the force is the center point, the suspension mechanism 5 that suspends the platform 4 and can make the platform 4 rotate or fall, the central processing unit 6, the installation The safety lock fixing mechanism 7 on the platform 4 and the stay-wire displacement sensor 8 installed on the first beam, the central processing unit 6 are respectively connected with the stay-wire displacement sensor 8 and the suspension mechanism 5, and the platform 4 is fixedly provided with an upwardly extending The first steel wire rope 9, the stay wire 81 of the stay wire displacement...

Embodiment 2

[0052] Embodiment 2: This embodiment is based on Embodiment 1. Central processing unit 6 also comprises 485 communication modules, and the circuit diagram of 485 communication modules is as Figure 10 As shown, the single-chip control module 61 is connected with the upper computer through the 485 communication module, and the qualified performance parameters of the safety lock are stored in the upper computer, and the single-chip control module transmits the performance parameters of the safety lock to be tested to the upper computer through the 485 communication module, and the upper computer The performance parameters of the safety lock to be tested are compared with the qualified performance parameters to determine whether the safety lock to be tested is qualified and save the corresponding data, thereby increasing the storage capacity and operability of the detection system.

Embodiment 3

[0053] Embodiment three: present embodiment is on the basis of embodiment one and embodiment two, and central processing unit also comprises buzzer circuit module, and the circuit diagram of buzzer circuit module is as Figure 11 As shown in the figure, when the platform is adjusted to a horizontal state, the buzzer circuit module emits a prompt sound.

[0054] According to the provisions of the national standard GB19155-2003 "Basket for Working at Heights", the swing arm type anti-tilt safety lock is required. When the vertical inclination angle of the suspended platform is not greater than 8°, it can be automatically locked and stop running. In the free fall detection, the suspension platform should stop running within the braking distance of no more than 100mm, so when the measured lock rope distance (that is, within 100mm, and the lock rope angle is within 8°), the quality of the safety lock can be considered to be up to standard. In all the above-mentioned embodiments, th...

Abstract

The invention discloses a detection system and detection method for a safety lock of a hanging basket. A platform is in shaft connection with a vertical beam and can move between a first cross beam and a second cross beam with the shaft connection point as a central circle point when stressed, a suspension mechanism suspends the platform and can enable the platform to rotate or drop down, a stay cable type displacement sensor is installed on the first cross beam, and a stay cable of the stay cable type displacement sensor is fixedly connected with a first steel wire rope. When the platform is located at the horizontal position, a connection line of the stay cable of the stay cable type displacement sensor and the first steel wire rope is perpendicular to the platform, a safety steel wire rope penetrates through the safety lock to be detected, the stay cable type displacement sensor transmits data to a central processing unit, the central processing unit processes the received data, and the decline vertical distance and inclination angle when the platform rotates from the horizontal state to the state when the safety steel wire rope is tightly locked by the safety lock are obtained. The detection system and detection method for the safety lock of the hanging basket have the advantages that the performance of the safety lock can be detected automatically, the automatic operation method is adopted, the operation method is simple, and detection efficiency and detection accuracy are high.

Description

technical field [0001] The invention relates to a hanging basket safety lock detection technology, in particular to a hanging basket safety lock detection system and detection method. Background technique [0002] With the rapid development of my country's construction industry, aerial work gondolas are widely used in various construction projects. According to the national mandatory standard GB19155-2003 "Basket for Height Operation", the safety lock means that when the sliding speed of the suspension platform reaches the speed of the lock rope or the inclination angle of the suspension platform reaches the angle of the lock rope, the safety wire rope can be automatically locked. A device that stops a suspended platform from sliding or tilting. As a necessary device to ensure the safety of the hanging platform, the safety lock's performance is particularly important. There are few systems specially designed for the detection of safety locks. The existing safety lock detec...
