Detailed implementation manners

[0023] This application provides a slag baffle device for a rock drilling jumbo, which is used to be installed on the rock drilling jumbo. The rock drilling jumbo includes a jumbo body, and also includes a drill rod movably installed on the jumbo body. The drill rod is an important tool for connecting the drill bit. The drill rod is used to transmit force and protect the operator from harm. The jumbo body and the drill rod of the rock drilling jumbo are well-known technologies in the art. For example, the jumbo body is provided with a driving mechanism for driving the drill rod to move back and forth, and the specific structure of the rock drilling jumbo will not be further described herein.

[0024] The slag baffle device for a rock drilling jumbo provided by this application is hereinafter simply referred to as the slag baffle device. Please refer to Figure 5 , the slag baffle device includes a base 100, a fastening screw 200 and a slag baffle plate 300, Figure 1 and Figure 2 shows the specific structure of the base 100, Figure 3 and Figure 4 shows the specific structure of the slag baffle plate 300.

[0025] Please refer to Figure 1 and Figure 2, the base 100 is provided with a plate portion 110, and the opposite ends of the plate portion 110 are bent to respectively form bent portions 120. In some embodiments, the cross-section of the bent portion 120 in the width direction is U-shaped. The plate portion 110 is installed on the trolley body. At this time, the slag blocking device is located in front of the drill rod of the rock drilling jumbo, realizing the assembly operation of the base 100 on the rock drilling jumbo. When drilling operations are carried out, the base 100 is located between the drill rod and the rock wall. In some embodiments, the plate portion 110 is provided with threaded holes 112, and the plate portion 110 is detachably connected to the trolley body through the threaded holes 112 in cooperation with bolts, facilitating the disassembly and replacement of the slag blocking device. In this application, the number of fastening screws 200 is multiple, and the multiple fastening screws 200 are respectively threadedly connected to the two bent portions 120, and the bent portions 120 cooperate with the fastening screws 200 to realize the assembly of the slag blocking disc 300 on the base 100.

[0026] Please refer to Figure 1 , in order not to obstruct the normal operation of the drill rod, the plate portion 110 of the base 100 is provided with a first avoidance hole 111, and the drill rod can pass through the first avoidance hole 111 of the plate portion 110 of the base 100, so that the base 100 does not obstruct the movement trajectory of the drill rod through the first avoidance hole 111.

[0027] Please refer to Figure 5 , the number of slag blocking discs 300 is two, and the slag blocking discs 300 are slidably assembled between the bent portions 120 at both ends of the plate portion 110. The two slag blocking discs 300 extend into the two bent portions 120 of the base 100 from left to right, and the slag blocking discs 300 are pressed on the base 100 through the fastening screws 200; when the fastening screws 200 are separated from the slag blocking discs 300, the slag blocking discs 300 can be pulled out along the bent portions 120. Please refer to Figure 3 and Figure 4 , the slag blocking disc 300 is provided with a disc body 310 and an elastic plate 320. The elastic plate 320 made of elastic material has elasticity, and the elastic plate 320 is stacked on the disc body 310. In some embodiments, the elastic plate 320 is detachably installed on the disc body 310. For example Figure 4 as shown, the elastic plate 320 and the disc body 310 are connected by screws 322. By replacing the elastic plate 320, the requirement for the number of disc bodies 310 is reduced, and the operation and maintenance cost of the slag blocking device is reduced.

[0028] Also in order not to obstruct the movement trajectory of the drill rod during drilling operations, both the slag blocking disc 300 and the elastic plate 320 are designed with avoidance holes. Under the condition that the slag blocking disc 300 has been installed on the base 100, a second avoidance hole 311 is jointly formed by the disc bodies 310 of the two slag blocking discs 300, and a third avoidance hole 321 is jointly formed by the elastic plates 320 of the two slag blocking discs 300. In the best implementation scheme, the structures of the two slag blocking discs 300 are the same, and the two slag blocking discs 300 are presented asFigure 5 In the symmetric arrangement case, half of the second avoidance hole 311 is located at the edge of one disc body 310, and the other half is located at the edge of the other disc body 310. Similarly, half of the third avoidance hole 321 is located at the edge of one elastic plate 320, and the other half is located at the edge of the other elastic plate 320. Specifically, please refer to Figure 5 , in this solution, the relative distribution and relative size of the second avoidance hole 311 and the third avoidance hole 321 are defined. The third avoidance hole 321 is within the projection area of the second avoidance hole 311 along the thickness direction of the slag retaining disc 300. Generally speaking, the second avoidance hole 311 is larger and the third avoidance hole 321 is smaller, so that the disc body 310 of the slag retaining disc 300 is far enough away from the movement track of the drill pipe, and the elastic plate 320 of the slag retaining disc 300 is as close as possible to the movement track of the drill pipe. Combining with the elastic performance of the elastic plate 320, it will not damage the drill pipe, and the elastic plate 320 can also block the rocks that directly impact the manipulator, drill pipe library and the auxiliary equipment of the drill pipe library near the drill pipe during the drilling operation as much as possible, reducing problems such as slag stones entering the drill rod library and causing gear jams, and improving the service life of the manipulator, drill pipe library and the auxiliary equipment of the drill pipe library.

[0029] On the other hand, by improving the impact of the rocks ejected during the drilling operation on the equipment, the flushing times of the drill pipe library with high-pressure water due to slag stone impact can be reduced, saving the comprehensive cost of rock drilling and perforation while reducing equipment wear.

[0030] In addition, the solution of the present application realizes the quick replacement of the slag retaining disc 300, so that the elastic plate 320 can be quickly replaced on the base 100, reducing the disassembly and assembly time of the elastic plate 320, and having great advantages in operation efficiency.

[0031] In some embodiments, the elastic plate 320 is made of rubber.

[0032] In some embodiments, in order to facilitate the pulling of the slag retaining disc 300 between the two bending parts 120, please refer to Figure 3 and Figure 4 , a handle 312 is connected to one end of the disc body 310, and the handle 312 is relatively far away from the second avoidance hole 311.

[0033] In some embodiments, the fastening screw 200 is in direct contact with the disc body 310, and the fastening screw 200 presses the disc body 310 against the base 100. As Figure 3 shown, the length and width of the elastic plate 320 are respectively smaller than the length and width of the disc body 310, and the contour of the elastic plate 320 is within the distribution range of the disc body 310.

[0034] In some embodiments, please refer to Figure 5, the shape of the third avoidance hole 321 corresponds to the circular cross-section of the drill pipe, and the third avoidance hole 321 is a circular hole.

[0035] In some embodiments, please refer to Figure 5 , the second avoidance hole 311 is a square hole. At this time, the side length of the square hole is greater than the diameter of the circular hole, meeting the set condition that the third avoidance hole 321 is within the projection area of the second avoidance hole 311 along the thickness direction of the slag retaining plate 300.

[0036] In some embodiments, the diameter of the circular hole is smaller than the outer diameter of the drill pipe. When the drill pipe moves back and forth, the drill pipe will squeeze the elastic plate 320, and by reducing the size of the third avoidance hole 321, the protection effect of the solution of the present application on the rock ejected during the drilling operation is further improved.

Therefore, the appended claims are intended to be construed to include the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.

[0038] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention is also intended to include these modifications and variations.
