Description

Technical Field

[0001] The invention relates to the technical field of rock stratum pre-splitting, and in particular to a hard rock stratum pre-splitting auxiliary crushing device and method. Background Art

[0002] Hard rock formations are usually difficult to crush or excavate directly on a large scale. Pre-splitting forms a regular network of cracks in the rock formation, which reduces the overall strength of the rock and makes subsequent crushing operations easier, making pre-splitting auxiliary crushing devices indispensable.

[0003] During operation, the existing pre-splitting auxiliary crushing device can only perform pre-splitting treatment on the rock formation by drilling holes. However, since the rock formation is relatively hard, after enough holes are drilled, the surface of the rock formation is still in a hard state, which requires drilling more holes again to make the rock formation between the holes become soft. The current pre-splitting auxiliary crushing device has low working efficiency, and a lot of time and cost are consumed in drilling holes, which is not conducive to the long-term construction period.

When the bevel gear 582 is meshed with the bevel teeth 452, the magnetic disk 421 will be magnetically connected to the magnetic attraction plate 583 to ensure that no separation will occur during the rotation process.

[0045] A protective cover 47 is provided on the outer surface of the drill bit 46, and a saw tooth 471 is provided at one end of the protective cover 47.

During the drilling process, the lower bottom surface of the collecting tube 48 will continuously approach the rock formation until the lower bottom surface of the collecting tube 48 contacts the surface of the rock formation. Then the staff needs to stop the drill bit 46 to prevent the drilling from being too deep and affecting the service life of the drill bit 46.

[0047] Specifically, the electric push rod C24 is used to make the drilling component 4 and the striking component 5 approach each other horizontally, and the electric push rod A52 is used to adjust the vertical position of the main plate 58, so that the bevel gear 582 is meshed with the bevel gear 452, and the electric push rod B43 and the electric push rod A52 are synchronously extended and retracted at the same frequency, and the tip of the drill bit 46 and the bottom of the striking plate 56 are in contact with the surface of the rock formation, and the main motor 44 is started. The main motor 44 will drive the drill bit 46 to rotate, and also drive the bevel gear 582 to rotate. The rotation of the bevel gear 582 will drive the spur gear 581 to rotate, and the rotation of the spur gear 581 will cause the half gear 57 to rotate, and the half gear The rotation of 57 will drive the upper connecting plate 55 to move upward. When the drill bit 46 is always in a rotating state, since the half gear 57 has only half a circle of teeth, the tooth plate 551 and the upper connecting plate 55 will only move upward a certain distance during the upward movement, and then move downward due to gravity, so that the knocking plate 56 hits the surface of the rock formation and uses the knocking to pre-crack the surface of the rock formation. In other words, when the drill bit 46 is used to pre-crack the rock formation by drilling holes, the knocking plate 56 can also knock the surface of the rock formation to pre-crack it, thereby improving the looseness between each borehole, making it easier to conduct subsequent construction, and indirectly improving the overall work efficiency and work quality.

[0048] In order to solve the technical problem of how to cool the drill bit 46, as Figure 2 , Figure 8 and Fig. 9 As shown, the following preferred technical solutions are provided:

A magnetic lifting plate 5623 is provided between the external plate 5621 and the side plate 5622. A control valve is provided on the outer surface of the external plate 5621. When the control valve is opened, water is added between the external plate 5621 and the side plate 5622. The water source is located at the upper end of the magnetic lifting plate 5623.

[0050] A slide groove 5624 is provided on one side of the side plate 5622, and a built-in rod 5625 is provided inside the slide groove 5624 for sliding. The built-in rod 5625 is magnetically connected to the magnetic lifting plate 5623, and a steel rod 5626 is provided at the lower end of the built-in rod 5625.

During the working process, the drill bit 46 and the protective cover 47 will be located in the protective groove 561, and the water sprayed from the nozzle 5628 will spray onto the surface of the protective cover 47, and the water will flow along the protective cover 47 to the drill bit 46 and the drill hole to cool the drill bit 46.

[0051] The support member 1 includes a support plate 11, a support seat 12 arranged at both ends of the support plate 11, a built-in groove is opened on the upper surface of the support plate 11, a telescopic rod 13 and a built-in block 14 are arranged inside the built-in groove, one end of the telescopic rod 13 is connected to the inner wall of the built-in groove, and the other end of the telescopic rod 13 is connected to the built-in block 14, a groove tube 15 is arranged at the upper end of the built-in block 14, a pad 16 is arranged at the upper end of the groove tube 15, a support column 17 is arranged at the upper end of the pad 16, and a connecting block 18 is arranged at the upper end of the support column 17. Two groups of support members 1 are provided, and the cross beam 2 is arranged between the two groups of support members 1. Through the telescopic rod 13, the built-in block 14 can be moved in the built-in groove, thereby driving the groove tube 15 to move, thereby driving the support column 17 and the cross beam 2 to move.

[0052] Specifically, during the working process, the steel rod 5626 will first contact the rock formation, and the rock formation will exert a reaction force, thereby causing the steel rod 5626 to move upward, and then causing the built-in rod 5625 to move upward. Since the built-in rod 5625 is magnetically connected to the magnetic lifting plate 5623, it can also drive the magnetic lifting plate 5623 to move upward. Before working, water is added between the external plate 5621 and the side plate 5622 in advance. When the magnetic lifting plate 5623 moves upward, the water will be squeezed, and the water will be squeezed into the drain pipe 5627, and finally sprayed from the nozzle 5628 to the surface of the protective cover 47. The water will flow along the protective cover 47 to the drill bit 46 and the drill hole, thereby cooling the drill bit 46 and increasing the service life of the drill bit 46.

[0053] The present invention also provides a technical solution, a method for implementing a hard rock pre-splitting auxiliary crushing device, comprising the following steps:

[0054] S1: Place the whole above the rock formation that needs to be pre-cracked, and determine whether to use the striking component 5 according to the needs. If the striking component 5 is not used, directly start the main motor 44, the main motor 44 will drive the drill bit 46 to rotate, and then extend the electric push rod B43 to complete the pre-crack of the rock formation;

[0055] S2: When the striking component 5 is needed, the electric push rod C24 is used to make the drilling component 4 and the striking component 5 approach each other horizontally, and the electric push rod A52 is used to adjust the vertical position of the main plate 58 so that the bevel gear 582 is meshed with the bevel gear 452;

[0056] S3: The electric push rod B43 and the electric push rod A52 are extended and retracted synchronously and at the same frequency, and the tip of the drill bit 46 and the bottom of the knocking plate 56 are in contact with the surface of the rock formation. The main motor 44 is started, and the main motor 44 drives the drill bit 46 to rotate, and also drives the bevel gear 582 to rotate. The rotation of the bevel gear 582 drives the spur gear 581 to rotate. The rotation of the spur gear 581 causes the half gear 57 to rotate. The rotation of the half gear 57 drives the upper connecting plate 55 to move upward.

[0057] S4: When the drill bit 46 is in a rotating state, since the half gear 57 has only half a circle of teeth, the tooth plate 551 and the upper connecting plate 55 will only move upward for a certain distance during the upward movement, and then move downward due to gravity, so that the knocking plate 56 hits the surface of the rock formation, and the rock formation surface is knocked and pre-cracked by knocking.
