Description

Technical Field

[0001] The utility model belongs to the technical field of mining rock mining machinery and equipment, in particular to a marble mining track rock saw based on an excavator. Background Art

[0002] In infrastructure construction such as foundation pit excavation, tunnel excavation, mining, rock cutting and development operations, there are many rock geology that need to be excavated. The various types of excavators used in the mining process are drill bits for drilling and splitting or cooperate with excavators with special hammers to crack rocks. It is an ideal non-explosive excavation equipment, which greatly improves work efficiency. These excavators are widely used in infrastructure construction, mining and rock excavation because of their mature and reliable technical structure, flexible and convenient movement, many manufacturers and large equipment holdings; using existing drill bits for drilling and splitting or special hammers In the expansion rock cutting method, during construction, the excavator's boom is pressed down to achieve the overall swing and lifting movement of the drill bit or hammer to split or expand the rock. To this end, it is necessary to continuously swing the boom and flip the drill bit or hammer to achieve cutting within a certain angle range. The boom of the excavator equipment has a large supporting force during the operation. The drill bit or hammer will produce huge vibrations during the splitting and cutting operation, which will cause the entire excavator to shake to a certain extent, which is not conducive to the sawing operation, and will cause the excavator's boom to bend and break the rock. Therefore, there is an urgent need for a device that can change the main structure of the sawing and cutting, and avoid the vibration of the excavator's boom during the rock mining and cutting operation. It is very necessary to make overall improvements to the existing equipment of this type. Utility Model Content

A transmission connecting rod 414 is arranged on the outer side of the vertical swing support frame 411, and one end of the transmission connecting rod 414 is rotatably connected to the lower swing support pin 413, and the other end of the transmission connecting rod 414 is rotatably connected to the side wall of the excavator swing arm 101.When the guide rail 1 rotates in a large range in the vertical direction through the excavator's boom (excavator swing arm 101), the vertical swing oil cylinder 410 is suspended and moved to the marble block cutting position through the horse-drawn head 5, and the vertical swing oil cylinder 410 pushes the horse-drawn head 5 through the vertical swing support frame 411, and the horse-drawn head 5 drives the guide rail 1 to rotate in the vertical direction through the angle adjustment pin 50. The transmission connecting rod 414 can prevent the guide rail 1 from swinging back and forth during the rotation process, so that the rotation angle of the guide rail 1 can be quickly adjusted, and then the guide rail 1 can be further accurately adjusted in the vertical direction through the horizontal swing assembly 40, so that the guide rail 1 rotates to the required horizontal angle state. ;

[0040] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
