Description

Technical Field

[0001] This utility model relates to an anti-winding device, specifically an anti-winding device for a coal drill. Background Technology

[0002] As an important tool for supporting the sidewalls of coal mine tunneling faces, pneumatic coal drills are used frequently. Improper operation during drilling can easily lead to accidents such as hand entanglement and water pipe entanglement causing injury, posing a high safety risk. In order to ensure the safety of personnel during anchoring operations and improve construction conditions, there is an urgent need for a pneumatic coal drill anti-entanglement device. Utility Model Content

[0003] To address the problems existing in the prior art, this utility model provides an anti-winding device for a pneumatic coal drill, comprising: a base and a stop bar. The base is installed on the housing on one side of the pneumatic coal drill spindle, and the end of the stop bar is fixed on the base, so that the stop bar is located on one side of the spindle. The stop bar and the spindle are spaced apart. The stop bar locks the water inlet of the water hyacinth, preventing it from rotating and winding with the drill rod on the spindle, thus solving the above problems.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: an anti-winding device for a pneumatic coal drill, comprising: a base and a stop bar. The base is installed on the housing on one side of the pneumatic coal drill spindle, and the end of the stop bar is fixed on the base so that the stop bar is located on one side of the spindle. The stop bar and the spindle are spaced apart. The stop bar locks the water inlet of the water hyacinth, preventing it from rotating and winding with the drill rod on the spindle.

[0005] Furthermore, the extension height of the stop lever is greater than the extension height of the main shaft.

[0006] Furthermore, the base is fixed to the housing of the coal drill by bolts.

[0007] Furthermore, the base is provided with through holes for mounting bolts.

[0008] Furthermore, the housing of the coal drill is provided with through holes or threaded holes for mounting bolts.

[0009] Furthermore, the base and the stop bar are connected by a threaded structure.

[0010] Furthermore, one end of the stop bar is welded to the base.

[0011] The beneficial effects of this utility model are as follows: When used in conjunction with a pneumatic coal drill, the water inlet of the water hyacinth is locked by a stop bar, so the user does not need to hold the water pipe during drilling, preventing the water pipe from rotating and getting tangled with the drill rod. It can adapt to various pneumatic coal drills underground, effectively improving construction safety. The device has a simple structure, is easy to use and manufacture, is safe and reliable, easy to operate, and has a high cost-performance ratio. It achieves the expected results and meets the usage requirements. It is recommended to promote its use. Attached Figure Description

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit its scope.

[0015] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention.

[0016] like Figure 1 As shown, an anti-winding device for a pneumatic coal drill includes: a base 1 and a stop bar 2. The base 1 is installed on a housing 4 on one side of the pneumatic coal drill spindle 3. The end of the stop bar 2 is fixed on the base 1, so that the stop bar 2 is located on one side of the spindle 3. The stop bar 2 and the spindle 3 are spaced apart. The stop bar 2 locks the water inlet of the water hyacinth, preventing it from rotating and winding with the drill rod on the spindle 3.

[0017] The extension height of the stop bar 2 is greater than that of the spindle 3, effectively preventing the water pipe from contacting the drill rod and solving the problem of entanglement between them.

[0018] The base 1 and the housing 4 of the coal drill are fixed together by bolts. That is, the base 1 is provided with through holes for mounting bolts, and the housing 4 of the coal drill is provided with through holes or threaded holes for mounting bolts. When the housing 4 of the coal drill is provided with through holes for mounting bolts, the bolts used for mounting need to have mounting nuts. When the housing 4 of the coal drill is provided with threaded holes for mounting bolts, the bolts do not need to have mounting nuts, and the mounting bolts are directly installed in the threaded holes.

[0019] The base 1 and the stop bar 2 are connected by a threaded structure or one end of the stop bar 2 is directly welded to the base 1.

[0020] The base 1 and the stop bar 2 are connected by a threaded structure: the base 1 is provided with a threaded hole for installing the stop bar 2, and the end of the stop bar 2 connected to the base 1 is provided with an external thread. The stop bar 2 is directly screwed onto the base 1. This detachable connection method makes it convenient to repair and replace in case of failure.

[0021] A coal drill anti-winding device can be made from waste materials when used in mining areas, which has good economic benefits. The stop bar 2 can be made from waste steel bar segments, and the base 1 can be made from waste steel plates. The steel plates are drilled with matching mounting holes, and the steel bar segments are fixed to the steel plates by welding. The device is simple to modify, easy to use, cost-effective, and saves costs.

[0022] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
