Detailed Description

In order that the above-recited objects, features and advantages of embodiments of the present invention can be more clearly understood, a further detailed description of embodiments of the present invention will be rendered by reference to the appended drawings and detailed description thereof. It should be noted that, in the case of no conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application, however, embodiments of the invention may be practiced otherwise than as described herein, and therefore the scope of the present application is not limited to the specific embodiments disclosed below.

In one embodiment according to the present invention, as shown in fig. 1, 2 and 6, the bolter 100 includes a carriage 110 and a drill box assembly 120. Specifically, the drill box assembly 120 is movably disposed on the carriage 110, and the drill box assembly 120 is capable of moving relative to the carriage 110. Further, as shown in fig. 1, 2 and 3, the carriage 110 includes a mounting plate 111 and at least three first guide rails 112. At least three first guide rails 112 are each connected to the mounting plate 111. The main function of the mounting plate 111 is to connect at least three first guide rails 112 together. Optionally, the first guide rail 112 is detachably connected with the mounting plate 111 by means of clamping or bolts, so that the assembly and disassembly are convenient, and the maintenance or replacement of parts is facilitated; alternatively, the first guide rail 112 and the mounting plate 111 are relatively fixed by welding, and the processing mode is simple; or, the first guide rail 112 and the mounting plate 111 are of an integrated structure, so that compared with a post-processing mode, the structure has the advantages of good mechanical property and high connection strength, and is beneficial to reducing the number of parts and improving the assembly efficiency.

It should be noted that the cross-sectional shape of the first rail 112 may be circular, square, triangular, oval, etc. Alternatively, the cross-sectional shape of the first rail 112 is circular, i.e., the first rail 112 is a cylindrical rail. By setting the cross-sectional shape of the first rail 112 to be circular, on the one hand, it is easy to process relative to other cross-sectional shapes; on the other hand, when the first rail 112 undergoes a minute deformation by a bending load, it is not easy to be jammed. Alternatively, the cross-sectional shape of the first guide rail 112 is square, and the first guide rail 112 has higher structural strength and is not easy to deform compared with the design mode that the cross-sectional shape is circular.

Further, the centerlines of the at least three first rails 112 are parallel to each other and are not coplanar. Of the at least three first rails 112, the center lines of each two first rails 112 are on one plane, and the at least two planes do not coincide. In other words, the center lines of every two first rails 112 define a plane, and at least two planes are not coplanar. By providing at least three first guide rails 112, the space layout is planned more scientifically and reasonably. In addition, the design can make the process of moving the drill box assembly 120 relative to the sliding frame 110 smoother.

Further, as shown in fig. 1 and 3, the drill box assembly 120 is sleeved on at least three first guide rails 112. The drill box assembly 120 moves relative to the carriage 110 along the centerline of the first rail 112. Optionally, the drill box assembly 120 is used to mount drill pipe. During the process of moving the drill box assembly 120 relative to the carriage 110, the drill rod can also move back and forth relative to the carriage 110, so as to achieve the purposes of drilling and punching. The drill box assembly 120 is loaded and driven in operation and is not balanced in force. The bolter 100 of the invention adopts at least three first guide rails 112 with the central lines parallel to each other but not in the same plane, can reduce the bending load born by the first guide rails 112, has more reasonable load born by the first guide rails 112, and is beneficial to prolonging the service lives of the guide rails and equipment.

It should be noted that the number of the first guide rails 112 is at least three, that is, the number of the first guide rails 112 may be three or more. The first guide rails 112 are flexibly arranged according to actual requirements, so long as the central lines of the plurality of first guide rails 112 are ensured to be parallel to each other but not to be in the same plane.

In the technical scheme defined by the invention, one guide rail or two guide rails in the traditional structure are changed into at least three first guide rails 112 with the central lines parallel to each other but not in the same plane, so that the space layout is planned more scientifically and reasonably; in the second aspect, the bending load borne by the first guide rail 112 can be reduced, the load borne by the first guide rail 112 is more reasonable, and the service life of the guide rail and the equipment is prolonged; in a third aspect, the movement of the drill box assembly 120 relative to the carriage 110 may be made smoother.

In one embodiment according to the present invention, as shown in fig. 1 and 3, the drill box assembly 120 includes a drill box 121. Specifically, the drill box 121 moves relative to the carriage 110 along the centerline of the first rail 112. Optionally, the drill box 121 is used to mount drill rods.

Further, the drill box 121 has oppositely disposed first and second sides 1211, 1212. At least two first rails 112 are provided on the first side 1211 and at least one first rail 112 is provided on the second side 1212. By planning the spatial layout of the first guide rails 112, it is ensured that the center lines of the plurality of first guide rails 112 are parallel to each other but not in the same plane. This design reduces the bending load on the first rail 112, and the load on the first rail 112 is more reasonable, which is beneficial to improving the service life of the rail and the equipment.

Alternatively, the number of first guide rails 112 is three. The centerlines of the three first rails 112 are parallel to each other and are not coplanar. Two of the first guide rails 112 are disposed on a first side 1211 of the drill box 121 and the other first guide rail 112 is disposed on a second side 1212 of the drill box 121.

Further, as shown in fig. 1 and 3, the drill box 121 includes a first side wall 1213 at a first side 1211 and a second side wall 1214 at a second side 1212.
