[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0023] Please refer to Figures 1-4The utility model provides the following technical scheme: A single -end wheel type rock drill, including frame 1, the inside of frame 1 is rotatively connected with chain 2 through chain wheel, the front end of frame 1 is installed with servo motor 3, the output shaft of servo motor 3 is connected with chain wheel, the surface of chain 2 is installed with fixed plate 4, the top of fixed plate 4 is installed with drive motor 5, the output shaft of drive motor 5 is installed with rock drill rod 6, the top of frame 1 is installed with the guide sleeve of rock drill rod 6, the bottom of frame 1 is installed with butt joint plate 7,

[0024] The front and rear ends of frame 1 are installed with fixed block 8, the surface of fixed block 8 is connected with guide rod 10, one end of guide rod 10 is connected with limit block 11, the surface of guide rod 10 is sleeved with spring 12, the other end of guide rod 10 is connected with buffer plate 9.

[0025] Specific use, single -end wheel type rock drill mainly by frame 1, chain 2, servo motor 3, fixed plate 4, drive motor 5 and rock drill rod 6 etc. component constitutes.In use, the rock drill needs to be installed on the wheel type walking mechanism.Wheel type walking mechanism starts, drives single -end wheel type rock drill to be close to rock, then, servo motor 3 starts work, and its output shaft will drive chain wheel to rotate, and chain wheel will in turn drive chain 2 to rotate.The rotation of chain 2 will drive fixed plate 4 to move, and the movement of fixed plate 4 will drive drive motor 5 to move together.Drive motor 5 works, will drive rock drill rod 6 to rotate, simultaneously, the advance of fixed plate 4 will push rock drill rod 6 to advance, thereby realizes the drilling operation to rock.

[0026] Preferably: limit block 11 is integrally connected with guide rod 10, limit block 11 and guide rod 10 are " T " shape.Guide rod 10 is longitudinally connected with three equally spaced distances.Buffer plate 9 can be connected with fixed block 8 through guide rod 10 and spring 12 and form elastic extension.

[0027] Specific use, in the movement of fixed plate 4, because there is spacing between chain 2 and chain wheel, will produce moving inertia, this makes fixed plate 4 extremely easy to impact with frame 1.When impact occurs, fixed plate 4 will contact with buffer plate 9, then drive guide rod 10 to move, and simultaneously extrude spring 12, make it shrink.Immediately, the reverse force of spring 12 can effectively buffer this moving inertia.Through this buffering mechanism, can efficiently absorb the impact force, avoid the deformation of frame 1 because of impact, thereby guarantee the stable operation of single -end wheel type rock drill, prolong the service life of equipment, and significantly improve work efficiency.

[0028] Preferably: the side wall of frame 1 is installed with support plate 13, and the side wall of frame 1 is provided with laser lamp 14.The surface of the mounting ear of laser lamp 14 is connected with bolt 15.Laser lamp 14 can be detachably fixedly connected with support plate 13 through bolt 15.

[0029] In specific use, the laser lamp 14 is fixed on the support plate 13 through the bolt 15, and then the laser lamp 14 is turned on, and the light emitted by the laser lamp 14 irradiates on the rock surface, thereby providing a clear and intuitive positioning guide for the drilling position of the rock drilling rod 6. In this way, the positioning of the drilling position in the rock drilling operation is significantly improved, the repeated operation or drilling failure caused by the positioning deviation is reduced, the rock drilling efficiency and operation quality are effectively improved, and the construction cost and time loss are reduced.

[0030] The working implementation principle is as follows: first, the laser lamp 14 is stably fixed on the support plate 13 through the bolt 15. After the laser lamp 14 is turned on, the light emitted by the laser lamp 14 accurately irradiates on the rock surface, thereby providing a clear and intuitive positioning guide for the drilling position of the rock drilling rod 6, and ensuring the accuracy of the rock drilling operation.

[0031] Then, the single-head wheeled rock drill slowly approaches the rock by means of the wheeled walking mechanism. At this time, the servo motor 3 is started to work, the output shaft of the servo motor 3 drives the chain wheel to rotate, and then the chain wheel drives the chain 2 to rotate. The rotation of the chain 2 drives the fixed plate 4 to move, and the movement of the fixed plate 4 drives the driving motor 5 to move together. When the driving motor 5 works, the rock drilling rod 6 rotates, and at the same time, the forward movement of the fixed plate 4 drives the rock drilling rod 6 to move forward, thereby realizing the drilling operation on the rock.

[0032] However, in the process that the fixed plate 4 moves from the left side of the rack 1 to the right side, due to the spacing between the chain 2 and the chain wheel, the moving inertia is generated, which causes the fixed plate 4 to be easily impacted when approaching the right side of the rack 1. When the impact occurs, the fixed plate 4 is in contact with the buffer plate 9, drives the guide rod 10 to move, and at the same time, extrudes the spring 12 to make it contract. Then, the reverse force generated by the spring 12 can effectively buffer the moving inertia, and through this buffering mechanism, the impact force can be efficiently absorbed, the rack 1 is prevented from being deformed due to the impact, thereby ensuring the stable operation of the single-head wheeled rock drill, prolonging the service life of the equipment, and significantly improving the working efficiency.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present application, and is not used to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacements for some technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
