Description

Technical Field

[0001] The utility model relates to the technical field of measurement, in particular to a measurement device for underground mining. Background Art

[0002] During the process of underground mining, it is necessary to measure the depth of some medium-depth holes. The traditional measurement method is to insert a wire into the bottom of the medium-depth hole and then pull out the wire to measure the length of the wire or use a tape measure to reach the bottom of the hole for measurement. There are practical problems such as large depth measurement errors, low measurement efficiency, and inconvenient carrying with this measurement method.

[0003] In order to improve the measurement efficiency and simplify the measurement steps, some designs will synchronously insert a tape measure into the medium-depth hole through a special measurement device. By reading the scale on the tape measure, the depth of the medium-depth hole can be understood. Through the above measurement method, there is no need to take out the wire, and the depth of the medium-depth hole can be obtained after the measurement, which improves the underground measurement efficiency to a certain extent.

[0004] However, in the process of measurement through the above technical solution, it is necessary to fix the measurement device to the tape measure. During the process of the tape measure moving synchronously with the measurement device and inserting into the medium-depth hole, it continuously rubs against the inner wall of the medium-depth hole. The surface of the tape measure is prone to wear during frequent measurements, affecting the measurement life. At the same time, through the above measurement method, it is necessary to insert the tape measure into the medium-depth hole. For the measurement of deeper medium-depth holes, there are still many inconveniences. Summary of the Utility Model

Detailed implementation manners

[0023] To make the above objects, features and advantages of the present utility model more obvious and understandable, the following will describe in detail the specific implementation manners of the present utility model with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific implementations disclosed below.

[0024] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there can also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation manner.

[0025] Referring to the attached Figure 1 - attached Figure 5 , a measurement device for underground mining, includes a storage device and a measurement device. The storage device is composed of a support plate 1, a bottom plate 4, a pulley 11 and a push-pull rod 12. The measurement device is composed of a plurality of measurement rods 7 and an elastic cord 8. The support plate 1 is provided with storage holes 2 for placing the measurement rods 7. The storage holes 2 can be a plurality of arranged in an array. The bottom plate 4 is provided with fixing holes 5, and ground nails 6 are installed in the fixing holes 5. The entire storage device can be fixed through the ground nails 6. The roller 3 is arranged on the bottom plate 4 through a support frame 9. The elastic cord 8 is wound around the roller 3. A return device 10 is arranged inside the roller 3, and the measurement rods 7 can be tightened during measurement.

[0026] The return device 10 here can select a common torsion spring to control the roller 3 to be in a normally wound state, and ensure that the elastic cord 8 is in a normally taut state during the measurement process.

[0027] Wherein the bottom end of the measurement rod 7 is the flat end 702 of the measurement rod, and the upper end is the protruding end 703 of the measurement rod. The two measurement rods 7 are inserted into each other to form a plug-in structure 705. The insertion method can be snap connection or screw connection.

[0028] In order to make the measuring rod 7 more accurate and stable during measurement, an elastic cord 8 is inserted through the inside of the measuring rod 7. A side opening 701 is provided on the side of the measuring rod 7 to facilitate the insertion of the elastic cord 8. Both sides of the side opening 701 extend inwards and outwards respectively to form staggered protective parts 704, effectively preventing the elastic cord 8 from escaping during the measurement process.

[0029] Finally, it should be noted that the lengths of the measuring rods 7 here are the same. The length can be obtained by calculating the number of measuring rods 7 multiplied by the unit length. At the same time, during the measurement process, the elastic cord 8 needs to be kept in a taut state. The measuring personnel sleeved the measuring rod 7 outside the elastic cord 8 and accurately docked two adjacent measuring rods 7. At this time, multiple measuring rods 7 form a relatively stable whole to complete the measurement of the depth of the medium-depth hole.

[0030] When the present utility model is in use, the entire storage device is transported to the measurement location. The ground nail 6 is taken out to fix the bottom plate 4. The measuring rod 7 is taken out and passed through the elastic cord 8. The end of the elastic cord 8 is fixed at the flat end 702 of the first measuring rod. The second measuring rod is taken out and passed through the elastic cord 8 and sleeved with the first measuring rod. The first measuring rod is inserted into the well. Then, the next measuring rod is continuously connected until the end of the first measuring rod touches the bottom of the hole. Through the storage hole 2 on the support plate 1, it can be quickly known how many measuring rods 7 are used. By measuring the size of the last measuring rod exposed, the depth of the well can be obtained. After the measurement, the measuring rod 7 is taken off and inserted into the storage hole 2. The storage device is provided with rollers for convenient transportation.

[0031] In this article, the mine survey is described by taking the medium-depth hole in the mine as an example, but in actual use, it includes but is not limited to the medium-depth hole.

[0032] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
