Description

Technical Field

[0001] The utility model belongs to the technical field of cableway safety detection, and particularly relates to a bracket cable-falling detection device. Background Art

[0002] The bracket cable-off detection system is one of the necessary safety monitoring systems for the cableway. The cable-off detection can ensure that the cableway stops immediately after the cable is off to prevent the accident from expanding, which has caused accidents such as the bracket being pulled and deformed, and the carrying cable being scrapped. The bracket cable-off detection system is installed on the cable-supporting pulley frame on the inlet and outlet rope side of the cableway bracket. After the carrying cable is out of the wheel groove, the U-shaped needle will be broken by the door frame. The U-shaped needle is connected to the U-shaped needle seat. The U-shaped needle seat feeds back the breakage of the U-shaped needle to the control system, and the cableway stops running. The role of the U-shaped needle is particularly important and directly participates in the safe operation control of the cableway.

[0003] However, the existing U-shaped needle holder adopts a separate connection control system for detection. When used for cable detachment detection of multiple stents, one stent needs to be equipped with a separate wire. 50 stents require as many as 50 detection wires, which not only puts a burden on the stent's load-bearing capacity and makes laying difficult, but also greatly increases the cost. Utility Model Content

[0004] In order to make up for the deficiencies of the prior art, the utility model provides a support cable-loosening detection device which can greatly reduce the number of detection lines, reduce costs, and quickly determine the cable-loosening position.

[0005] The utility model is realized through the following technical solutions:

[0006] A device for detecting a detached cable of a support comprises a U-shaped needle holder, on which a U-shaped needle is mounted, and is characterized in that: the U-shaped needle holder comprises a patch holder, in which a dial integrator is arranged, the dial integrator comprises a circuit board, patch resistors are arranged on the front and back sides of the circuit board respectively, a dial switch is arranged across the patch resistor on the front side of the circuit board, a terminal is mounted on the back side of the circuit board, and the U-shaped needle is fixed in the terminal and connected to the dial integrator.

[0007] A cutting groove is arranged at one end of the terminal connected to the circuit board, and clamping wheels for fixing the U-shaped needle are arranged on both sides of the patch seat.

[0008] The dialing integrator is provided with a sealing cover fixed on the patch seat.

[0009] A sealing ring is arranged between the sealing cover and the patch seat.

[0010] The beneficial effects of the utility model are as follows: by adopting single-line detection, all U-shaped needle seats can be connected in series by one line, which greatly reduces the number of detection lines and reduces the cost. Moreover, by setting the bracket position through the dial code integration, the cable detachment position can be quickly and accurately determined after the U-shaped needle breaks.

DETAILED DESCRIPTION

[0021] The accompanying drawings are a specific embodiment of the utility model. This embodiment includes a U-shaped needle holder 1, on which a U-shaped needle 2 is installed, the U-shaped needle holder 1 includes a patch holder 3, a dial integrator 4 is arranged in the patch holder 3, the dial integrator 4 includes a circuit board 5, and patch resistors 6 are arranged on the front and back of the circuit board 5, respectively. A dial switch 7 is arranged across the patch resistor 6 on the front of the circuit board 5, and a terminal 8 is installed on the back of the circuit board 5. The U-shaped needle 2 is fixed in the terminal 8 and connected to the dial integrator 4. A cutting groove 9 is provided at one end of the terminal 8 connected to the circuit board 5, and clamping wheels 10 for fixing the U-shaped needle 2 are provided on both sides of the patch holder 3. A sealing cover 11 fixed on the patch holder 3 is provided on the outside of the dial integrator 4. A sealing ring 12 is provided between the sealing cover 11 and the patch holder 3.

[0022] The present practical bracket cable detachment detection device is adopted, and the clamping wheel 10 is an externally threaded hand wheel, which is rotated to compress the U-shaped needle 2 inward. The code integrator 4 includes a circuit board 5, a code switch 7, a chip resistor 6 and a terminal 8. The code switch 7 is an on-off switch, and the chip resistor 6 is placed on the front and back sides of the circuit board 5. The code switch 7 straddles the chip resistor 6 on the front side to short-circuit and disconnect the chip resistor 6. The terminal 8 is a hollow cylinder, and a groove 9 is provided at one end of the terminal 8 connected to the circuit board 5. The clamping wheel 10 squeezes the terminal 8 on one side of the groove 9 to fix the U-shaped needle 2 in the terminal 8. The code integrator 4 is connected to the PLC control system to facilitate the calculation and display of the bracket position.

[0023] The method of use is as follows: the patch seat 3 is installed on the bracket base (each existing bracket is equipped with a base) by bolts. Insert the U-shaped needle 2 into the front hole of the terminal 8, fix the U-shaped needle 2 in the terminal 8 by tightening the clamping wheel 10, and connect the U-shaped needle 2 to the dial switch 7 on the circuit board 5 through the terminal 8. Install the assembled detection device on the base of the first bracket, turn the dial switch 7 to the open position, and so on, and continue to install the detection device of the subsequent bracket. Different resistance settings are achieved by different combinations of the dial switch 7, and the resistance settings of the detection devices on the same bracket are the same. In the initial circuit, the resistance of the U-shaped needle 2 is close to zero, and the overall resistance is mainly the line resistance. Taking the line of 2000 meters as an example, the resistance is 80 ohms. After the cable is removed, the U-shaped needle 2 breaks, and the resistance on the dial integrator 4 is connected in series in the circuit. The current calculation formula is that the current is equal to the voltage divided by the resistance. The changed resistance value can be obtained according to the current change, and the correspondingly set dial integrator 4 can be obtained according to the resistance value, and then the bracket position is determined.

[0024] The DIP switch 7 is turned on and off, and the resistance value is set to determine the position of the switch. When the U-shaped needle 2 is disconnected, the line resistance changes, thereby determining the position of the bracket. Since the resistance value of the DIP switch 7 of each bracket is different, the position is unique. There are no multiple brackets disconnected at the same time. This situation occurs due to irresistible external forces, earthquakes and other natural disasters. At this time, there is no need to start the cableway and it cannot be used.
