Description

Technical Field

[0001] This utility model belongs to the field of well chute ranging technology, specifically relating to a radar ranging auxiliary device. Background Technology

[0002] Previously, measuring the depth of a chute involved multiple people extending a steel pipe horizontally into the chute opening. A limiting hole was set at the top of the pipe, through which a steel wire rope was threaded. The other end of the pipe was then weighed down with stones or other heavy objects. This process was fraught with safety risks and inaccurate measurements. With daily use, the steel wire rope often got stuck at the limiting hole, preventing it from reaching the deepest part of the chute and leading to inaccurate results. Furthermore, getting stuck also caused wear and tear and rope breakage. Replacing the rope required multiple people working together, and the process of moving the steel pipe out of the chute opening also posed safety risks. Accidents of people falling into chutes occur frequently both domestically and internationally. Most chutes are over 100 meters deep, and once someone falls in, there is virtually no chance of survival. Utility Model Content

[0003] The purpose of this invention is to provide a radar ranging auxiliary device to solve the problems of safety risks and inaccurate measurements in the original well chute measuring method.

[0004] The technical solution of this utility model is as follows: a radar ranging auxiliary device, including a base plate and an L-shaped measuring tube. A base column is provided on the base plate, and the upper end of the base column is rotatably connected to the vertical section of the measuring tube. A wire rope winch is provided on the measuring tube. A first measuring crossbar is passed through the straight section of the measuring tube. Pulley devices are provided on the upper and lower sides of the measuring tube respectively. The wire rope winch is connected to the first measuring crossbar through a wire rope passing through the pulley device on the upper side of the measuring tube. A radar fixing device is provided at the end of the first measuring crossbar. A measuring radar transmitter is provided at the bottom of the radar fixing device. A power distribution box is provided on the base column. The power distribution box is electrically connected to the measuring radar transmitter through a cable passing through the pulley device on the lower side of the measuring tube. A data receiving display is provided inside the power distribution box.

[0005] As a further improvement of this utility model, a limiting post is provided at the upper end of the base column, the limiting post passes through the vertical section of the measuring tube, a limiting hole disc is provided at the connection between the base column and the limiting post, and a limiting pin is provided on the outer side of the vertical section of the measuring tube, the limiting pin and the limiting hole disc are matched and engaged.

[0006] As a further improvement of this utility model, a counterweight is provided on the base plate.

[0008] As a further improvement of this utility model, a limiting hole is provided on the second measuring crossbar.

[0009] The beneficial effects of this utility model are as follows: The installation of this utility model only requires the drilling rig to drill a hole of about 1 meter in the safe area of ​​the wellhead, and then insert this utility model into the hole and bury it. At the same time, the measuring tube of this utility model has a rotation function. After measuring the depth of the wellhead, the entire facility can be rotated to a safe area to achieve the purpose of setting up the measuring device and ensuring safe production.

[0010] This invention facilitates the improvement of accuracy in vertical depth measurement data for open-pit mine ore passes. Utilizing the principle of radar ultrasonic ranging, it enhances the accuracy of measurement results. Furthermore, it addresses safety issues during ore pass measurements by maintaining a safe distance of at least 5 meters between the measuring personnel and the ore pass opening, ensuring their safety. Finally, it resolves the problem of small-sized mine shaft filling equipment affecting the installation of measuring facilities. By incorporating rotating elements such as pulleys, the entire device can be rotated to a safe area for rope replacement, eliminating the risk of rope breakage due to wire jamming and the difficulty of rope replacement.

Detailed Implementation

[0015] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0016] like Figures 1-2As shown, a radar ranging auxiliary device includes a base plate 1 and an L-shaped measuring tube 4. A base column 2 is provided on the base plate 1, and the upper end of the base column 2 is rotatably connected to the vertical section of the measuring tube 4. A wire rope winch 3 is provided on the measuring tube 4. A first measuring crossbar 41 is inserted through the straight section of the measuring tube 4. Pulley devices 5 are provided on the upper and lower sides of the measuring tube 4, respectively. The wire rope winch 3 is connected to the first measuring crossbar 41 by passing through the pulley device 5 on the upper side of the measuring tube 4 with a wire rope 32. A radar fixing device 6 is provided at the end of the first measuring crossbar 41. A measuring radar transmitter 61 is provided at the bottom of the radar fixing device 6. A power distribution box 7 is provided on the base column 2. The power distribution box 7 is electrically connected to the measuring radar transmitter 61 by passing through the pulley device 5 on the lower side of the measuring tube 4 with a cable 71. A data receiving display 72 is provided inside the power distribution box 7.

[0017] A limiting post 8 is provided at the upper end of the base column 2, and the limiting post 8 passes through the vertical section of the measuring tube 4. A limiting hole disc 81 is provided at the connection between the base column 2 and the limiting post 8. A limiting pin 82 is provided on the outer side of the vertical section of the measuring tube 4, and the limiting pin 82 is matched and engaged with the limiting hole disc 81. A counterweight block 11 is provided on the base plate 1. A second measuring crossbar 43 is provided between the first measuring crossbar 41 and the bend of the measuring tube 4. A limiting hole 42 is provided on the second measuring crossbar 43.

[0018] The design principle of this utility model is as follows: Multiple pulley devices 5 ensure the smooth operation of the measuring wire rope 32 and cable 71; the reasonable combination of the wire rope winch 3, wire rope 32, pulley devices 5, and first and second measuring crossbars 41 and 43 of different lengths with the measuring tube 4 increases the measuring distance and further enables the first measuring crossbar 41 to extend and retract forward; the entire device is disassembled into a base plate 1, counterweight 11, wire rope winch 3, measuring tube 4, first measuring crossbar 41, second measuring crossbar 43, measuring radar transmitter 61, and data receiver display 72, etc., allowing for easy disassembly and relocation, adaptability to local conditions, and reuse; the use of radar ultrasonic ranging principle improves the accuracy of measurement results, providing data support for production organization.

[0019] Place this utility model 5 meters away from the wellhead to be measured, and add a counterweight 11 to the base plate 1 to ensure the stability of the entire device. When measurement is required, rotate the measuring tube 4 to the center point of the wellhead, and insert the limiting pin 82 into the limiting hole disc 81. The starting position of the wire rope 32 is fixed by the wire rope fixing knob 31 on the wire rope winch 3. The two wire ropes 32 at both ends of the first measuring crossbar 41 and the wire rope 32 on the wire rope winch 3 form a closed circle. By rotating the wire rope winch 3 in both directions, the first measuring crossbar 41 can be extended and retracted in the measuring tube 4. Rotating the wire rope winch 3 extends the first measuring crossbar 41 until the measuring radar transmitter 61 is close to the center of the wellhead. Open the power distribution box 7, press the measurement button, and the cable 71 drives the measuring radar transmitter 61 into the well. Record the measurement data displayed on the data receiving display 72, and close the power distribution box 7. Rotate the wire rope winch 3 to retract the first measuring crossbar 41 and open the limiting pin 82. Rotate the measuring tube 4 to the safe area and insert the limiting pin 82, thus completing one measurement operation. When the actual measuring distance is insufficient, a second measuring crossbar 43 is set between the bend of the first measuring crossbar 41 and the measuring tube 4. The limiting hole 42 is an anti-disengagement hole with a pin. The connection of the second measuring crossbar 43 inside the measuring tube 4 is fixed through the limiting hole 42, thereby increasing the measuring distance and meeting the needs of longer measuring distances.

[0020] This utility model has been put into use in the No. 2 ore pass of a mining company in Gansu Province. During use, it has effectively improved the accuracy of ore pass depth measurement results, reduced the safety risks caused by the measurement personnel being close to the wellhead during the measurement process, and greatly shortened the time for measuring ore pass depth due to its simple operation.
