Abstract
Description
Technical Field
[0001] The utility model relates to the field of coal mine gas control, in particular to a sliding rod device for prediction and forecast drilling in coal mine construction. Background Technique
[0002] When carrying out prediction and forecast work in coal mines, a pneumatic coal drill is usually used in cooperation with a drill bit with a diameter of 42 mm to construct prediction and forecast drill holes. At present, when constructing drill holes, usually two workers lift the pneumatic coal drill together and push the drill hole at the same time to drill the hole. Therefore, during the operation of prediction and forecast drill holes, the whole process depends on the physical strength of the workers for support. Since workers need to continuously construct multiple drill holes, the labor intensity of the workers is high and the physical strength is consumed a lot. As time goes by, the efficiency of constructing drill holes will also decrease, which not only increases the work intensity of the staff, but also has certain potential safety hazards, which is rather inconvenient. Content of the Utility Model
[0003] The purpose of the utility model is to provide a sliding rod device for prediction and forecast drilling in coal mine construction in view of the deficiencies and defects in the prior art. This device uses a steel pipe as the track for the pneumatic coal drill to move forward or backward, and adjusts the position and height of the pneumatic coal drill through an iron chain to adjust the azimuth and inclination angle of the drill hole, so that the pneumatic coal drill can slide back and forth on the steel pipe by manual pushing. When workers construct drill holes, they only need to push the pneumatic coal drill forward or backward, thus eliminating the need for manual lifting of the pneumatic coal drill, saving physical strength, reducing labor intensity, and the device is simple to process, can use the existing raw materials in the mine, does not require additional purchase, and can be processed by itself, with the characteristics of simple operation, convenient use, and no increase in too many processes.
[0004] To achieve the above object, the utility model adopts the following technical solutions: A sliding rod device for prediction and forecast drilling in coal mine construction, which includes an iron chain 2, a track steel pipe 3, a connecting rotating shaft 4, and a pneumatic coal drill 5. The two ends of the track steel pipe 3 are welded to the lower end of the iron chain 2. The upper part of the iron chain 2 is arranged on a support frame 1, and a connecting rotating shaft 4 is slidably connected to the track steel pipe 3, and the pneumatic coal drill 5 is movably connected to the connecting rotating shaft 4.
[0005] Further, one end of the iron chain 2 is welded to the track steel pipe 3, and a hook 201 is provided at the other end of the iron chain 2.
[0006] Further, the track steel pipe 3 is a steel pipe with a diameter of six points and a length of two meters.
[0007] After adopting the above technical solution, the beneficial effects of the utility model are as follows: The device uses steel pipes as the tracks for the forward or backward movement of the pneumatic coal drill, and adjusts the position and height of the pneumatic coal drill through iron chains to adjust the azimuth and inclination angle of the drill hole, so that the pneumatic coal drill can be pushed manually and slide back and forth on the steel pipes. When workers are constructing the drill hole, they only need to push the pneumatic coal drill forward or backward, thus eliminating the need for manual lifting of the pneumatic coal drill, saving physical strength, reducing labor intensity, and the device is simple to process, can utilize the existing raw materials in the mine, does not require additional purchase, and can be processed independently, with the characteristics of simple operation, convenient use, and no increase in too many processes.

[0012] Explanation of the reference numerals: support frame 1, iron chain 2, track steel pipe 3, connecting rotating shaft 4, pneumatic coal drill 5, I-beam 101, hook 201. Detailed Description of the Preferred Embodiment
[0013] Referring to Figures 1 - 3 As shown, the technical solution adopted in this specific embodiment is as follows: It includes an iron chain 2, a track steel pipe 3, a connecting rotating shaft 4, and a pneumatic coal drill 5. The two ends of the track steel pipe 3 are welded to the lower end of the iron chain 2. The upper part of the iron chain 2 is arranged on the support frame 1, and a connecting rotating shaft 4 is slidably connected to the track steel pipe 3, and the pneumatic coal drill 5 is movably connected to the connecting rotating shaft 4.
[0014] More specifically, one end of the iron chain 2 is welded to the track steel pipe 3, and a hook 201 is provided at the other end of the iron chain 2. By adjusting the position of the hook 201 hanging on the iron ring of the iron chain 2, the hanging height of the iron chain 2 is adjusted.
[0015] More specifically, the track steel pipe 3 uses a steel pipe with a diameter of six points and a length of two meters. The steel pipe has better wear resistance and support strength.
[0016] Working principle of the utility model: When it is necessary to drill prediction and forecasting holes underground during construction, the staff can first hang the track steel pipe 3 on the I-beam 101 of the support frame 1 at different front and rear positions through the iron chain 2. The staff can change the hanging position of the iron chain 2, and thus the azimuth of the drill hole. They can also hang the hook 201 at the movable end of the iron chain 2 at different positions of the iron ring of the iron chain 2 to adjust the angle of the drill hole. Then, connect the connecting rotating shaft 4 to the pneumatic coal drill 5 and install the connecting rotating shaft 4 on the track steel pipe 3. Then, re-check the azimuth and angle of the drill hole again. During construction, two workers hold the handle of the pneumatic coal drill 5 tightly, one on the left and the other on the right, and jointly push the pneumatic coal drill 5 to drill along the steel pipe track 3; when the drill rod completely enters the coal body, the worker retreats the pneumatic coal drill 5 to the starting position, adds the drill rod, and drills again until the specified depth is reached. When withdrawing the drill, the worker pulls the pneumatic coal drill 5 to retreat along the steel pipe track 3 and withdraws the drill rod until the drill rod is completely withdrawn, and a drill hole construction is completed. Repeat in sequence to complete the prediction and forecasting drill hole operation for coal mine construction. Among them, U-shaped steel can also be used as the support on the support frame 1.
[0017] The above is only used to illustrate the technical solution of the utility model and not to limit it. Any other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solution of the utility model, as long as they do not depart from the spirit and scope of the technical solution of the utility model, shall be covered by the scope of the claims of the utility model.
