The bracket 3 and the pressure plate 1 can be connected together by multiple connecting bolts 2, and then the mounting beam 13 is inserted between the bracket 3 and the pressure plate 1. The mounting beam 13 is clamped between the bracket 3 and the pressure plate 1, thereby completing the installation of the device. The device can be installed on the mounting beam 13 at a suitable position of the cableway to ensure that the cableway wire rope 12 passes directly above the cable wheel 11. The cableway hoist load online detection device is suitable for various cableway transportation scenarios. The installation and operation of the device does not require large-scale modification of the existing cableway structure. It is easy to install and simple to operate.

The position of the adjustment seat 5 can be adjusted by loosening the fixing bolt 4 and then driving the fixing bolt 4 to move up and down in the strip hole. After the adjustment, tighten the fixing bolt 4 and install the data acquisition sensor 6 on the adjustment seat 5. Adjust the matching degree between the data acquisition sensor 6 and the adjustment seat 5, and fix it on the bracket 3 by the fixing bolt 4. The installation position of the adjustment seat 5 can be adjusted up and down to better adapt to different working environments and needs.

The data acquisition sensor 6 is connected to the multifunctional instrument 7 via a data line 14, and the real-time acquired data can be displayed and processed on the instrument.

The bracket 3 has an installation hole at the upper end, in which an installation column 15 is vertically fixedly installed, a moving hole is formed through the upper end of the installation column 15, a stepped conductive column 16 is vertically slidably installed in the movable hole, the lower end of the conductive column 16 is in contact with the output end of the data acquisition sensor 6, and a wheel fork 10 is fixedly installed at the upper end, a cable wheel 11 is rotatably installed on the wheel fork 10, and the wire rope 12 is in rolling contact with the cable wheel 11;

The device is installed on a mounting beam 13 at a suitable position of the cableway. The steel wire rope 12 moves through the cable pulley 11 on the device. When the sling mounted on the steel wire rope 12 passes through the device, under the action of gravity, the conductive column 16 is driven to move vertically downward and squeeze the output end of the data acquisition sensor 6. The data acquisition sensor 6 is responsible for real-time monitoring of the changes in the load of the cableway sling. The data acquisition sensor 6 transmits these data to the remote multifunctional instrument 7 for data analysis and processing;

The principle of the device is based on the measurement principle of pressure sensor and strain sensor, which can realize real-time monitoring and data analysis of the spreader load and automatic alarm of load overload. The alarm signal can be connected to the control system to realize the control of spreader overload and ropeway parking, effectively improving the safety of ropeway operation. In addition, the data acquisition sensor 6 signal can also be connected to PLC, data recorder, etc., for more in-depth data analysis and processing.

The mounting column 15 is symmetrically provided with strip-shaped key holes 17, and guide keys 9 are vertically slidably installed in the two key holes 17. The two guide keys 9 are fixedly connected to the conductive column 16. The guide keys 9 slide up and down in the key holes 17 to ensure that the cable wheel 11 and the fork 10 combination maintain a fixed angle, and there will be no deflection or shaking when the fork 10 is raised and lowered.

The lower end of the mounting column 15 is provided with an annular thread groove connected with the moving hole, and an adjusting sleeve 8 is threadedly inserted in the thread groove. A support block 18 is fixedly installed at the lower end of the adjusting sleeve 8. The conducting column 16 is composed of a first moving column 1601 with a larger diameter and a second moving column 1602 with a smaller diameter. The first moving column 1601 is slidably installed in the moving hole, and the lower end of the second moving column 1602 contacts the output end of the data acquisition sensor 6.

When the adjustment sleeve 8 is used, when the wheel fork 10 is subjected to increased gravity, the moving length of the conductive column 16 will be larger. Under the action of the adjustment sleeve 8, after the conductive column 16 moves a moving distance, the lower end of the first moving column 1601 on the conductive column 16 will contact the support block 18, thereby limiting the conductive column 16 from continuing to move, which can ensure that the data acquisition sensor 6 is not damaged in the case of over-range.

A rotating hole is provided on the bracket 3, a threaded rod 19 is rotatably mounted on the bracket 3, a moving block 20 is threadedly sleeved on the threaded rod 19, one end of the threaded rod 19 passes through the rotating hole and is fixedly mounted with an adjusting block 21, a support rod 22 is rotatably mounted on the lower surface of the adjusting seat 5, a positioning groove is provided on the upper surface of the moving block 20, and the lower end of the support rod 22 is inserted into the positioning groove;

After the position of the adjusting seat 5 is adjusted, the adjusting block 21 can be rotated to drive the threaded rod 19 to rotate, and then the threaded rod 19 can be used to drive the moving block 20 to move horizontally on the bracket 3. During the movement of the moving block 20, the support rod 22 is rotated to align one end of the support rod 22 with the positioning groove until the moving block 20 inserts one end of the support rod 22 into the positioning groove. In this way, when the adjusting seat 5 is subjected to excessive vertical downward force, the adjusting seat 5 is prevented from moving under the restriction of the moving block 20 and the support rod 22.

An oil chamber 23 is provided in the mounting column 15, and the oil chamber 23 is filled with lubricating oil. An oil filling pipe 24 is fixedly installed on the side of the mounting column 15. An oil filling hole connected to the oil filling pipe 24 is provided on the inner wall of the oil chamber 23. A sealing plug 25 is inserted at one end of the oil filling pipe 24. A plurality of oil inlet holes connected to the oil chamber 23 are provided on the inner wall of the movable hole.

Lubricating oil can be injected into the oil chamber 23 through the oil filling pipe 24. The lubricating oil in the oil chamber 23 can penetrate into the inner wall of the movable hole and the surface of the conductive column 16 through the oil inlet hole, thereby reducing the friction between the surface of the conductive column 16 and the inner wall of the movable hole, and avoiding the accuracy of real-time load detection being affected by the large friction between the surface of the conductive column 16 and the inner wall of the movable hole.

A plurality of arc-shaped installation grooves are provided on the inner wall of the movable hole, each of which is connected to the plurality of oil inlet holes. A movable plate 26 is slidably installed in the arc-shaped installation groove. A spring rod 27 is symmetrically fixedly installed at the lower end of the movable plate 26. The lower ends of the two spring rods 27 are fixedly connected to the inner wall of the arc-shaped installation groove. A blocking block 28 is fixedly installed at the upper end of the movable plate 26. The blocking block 28 is inserted into the oil inlet hole. The movable plate 26 contacts the conductive column 16.

The blocking block 28 is inserted into the oil inlet hole under the action of the spring rod 27 and the movable plate 26, thereby blocking the oil inlet hole. At this time, the lubricating oil in the oil chamber 23 cannot pass through the oil inlet hole. During the movement of the conductive column 16, the friction between the conductive column 16 and the movable plate 26 will be smaller than the elastic force of the spring rod 27, and relative sliding will occur at this time. As the device is used for a long time, a small amount of dust will enter between the conductive column 16 and the mounting hole, so that the friction between the conductive column 16 and the movable plate 26 will increase until the friction force The elastic force of the spring rod 27 is greater than that of the spring rod 27. Then, under the action of friction, the movable plate 26 will be driven to move vertically downward, the spring rod 27 is compressed, and at the same time, the blocking block 28 moves vertically downward to open the oil inlet hole. At this time, the lubricating oil in the oil chamber 23 will penetrate through the oil inlet hole and penetrate between the inner wall of the mounting hole and the surface of the conductive column 16. At the same time, the friction between the conductive column 16 and the movable plate 26 is reduced. Under the action of the elastic force of the spring rod 27, the movable plate 26 moves vertically upward, and drives the blocking block 28 to be inserted into the oil inlet hole to block the oil inlet hole.

In the present invention, when the sling mounted on the wire rope 12 passes through the device, under the action of gravity, the conductive column 16 will be driven to move vertically downward and squeeze the output end of the data acquisition sensor 6. The data acquisition sensor 6 is responsible for real-time monitoring of changes in the load of the cableway sling. The data acquisition sensor 6 transmits these data to the remote multi-functional instrument 7 for data analysis and processing. It can perform online real-time and accurate monitoring of the load of the cableway sling, and can realize automatic alarm for load overload. The alarm signal can be connected to the control system to realize control such as sling overload and cableway parking, thereby effectively improving the safety of cableway operation.
