[0023] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical solutions in the utility model will be described clearly and completely below in combination with the drawings in the specific embodiments. Obviously, the embodiments described below are only some of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the patent, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the patent.

[0024] In a typical embodiment of the utility model, as shown in Figs. 1-2 A self-propelled large-diameter raiseboring machine special track chassis is provided, comprising: a chassis frame 1, a track assembly 2 and a leg assembly, the track assembly 2 is detachably mounted on both sides of the chassis frame 1, and the leg assembly is fixedly installed at the corners of both ends of the chassis frame 1.

[0025] The chassis frame 1 is cut and assembled and welded from sheet metal, and each assembled component is provided with holes according to design requirements, leaving a pipe-laying and wiring channel for hydraulic pipes and electric wires and cables, and some holes are used as welding process holes to facilitate welding between each connecting part.

[0026] As shown in Fig. 2 The chassis frame 1 is composed of a chassis main body and a track mounting support 3, specifically, the chassis main body is in the shape of an I-beam, including a vertical beam and two horizontal beams, the two horizontal beams are fixedly arranged at both ends of the vertical beam, and one mounting hole is arranged at each corner of both ends of the chassis main body for mounting the leg assembly, the track mounting support 3 is fixedly arranged on the side walls of both sides of the vertical beam of the chassis main body by welding, bolt connection or one-piece forming, for mounting the track assembly 2, the track mounting support 3 is an inverted L-shaped structure, including a horizontal plane and a vertical plane perpendicular to each other, the horizontal plane is above the vertical plane, and a plurality of bolt holes are arranged on the horizontal plane and the vertical plane to connect the track assembly 2 by bolt connection, the two perpendicular connecting surfaces increase the contact area and the connection points, effectively improving the connection stability and firmness between the track assembly 2 and the chassis main body.

[0027] As shown in Fig. 1As shown, the crawler assembly 2 is a crawler walking structure. The crawler assembly 2 includes a walking crawler and a hydraulic walking motor, and the hydraulic motor drives the crawler assembly 2 to work, thereby realizing crawler walking. The crawler assembly 2 has a large transmission ratio range, compact structure, high working efficiency, strong reliability, small size, balanced operation, and low noise. It also has the characteristics of multi-level protection, long service life, and large output torque. It can effectively carry the whole machine to walk on flat ground and up and down gentle slopes. Compared with the tire walking structure, it has stronger adaptability.

[0028] Since the chassis body is in an I-shape, when the crawler assembly 2 is installed on both sides of the chassis body, the width of the chassis body can be maintained without increasing the overall dimensions (width), thereby ensuring that the overall width of the shaft drill meets the requirements for traveling in underground mine tunnels.

[0029] The leg assembly includes four legs 4. There are four mounting holes at the corners of both ends of the chassis body. A leg 4 is installed in each mounting hole. The legs 4 are vertically arranged to support the chassis frame 1 as a whole. The legs 4 are structures such as hydraulic jacks and hydraulic cylinders. The four legs can adjust the telescopic length of each leg 4 individually, or any two legs 4 can be combined to adjust the telescopic length together. When working, the legs 4 are supported on the working plane. By adjusting the telescopic length of the specified leg 4, the overall height of the chassis frame 1 is lifted and its levelness is adjusted, thereby lifting the overall height of the drilling rig and adjusting the levelness of the drilling rig, and maintaining the balance and stability of the drilling rig when it is working.

[0030] like Fig. 2 As shown, an installation groove 9 is provided on the upper surface of the vertical beam of the chassis body. The installation groove 9 is a rectangular recessed structure. The installation groove 9 is close to the working end of the chassis body (that is, one end for installing the drilling rig; the other end of the chassis body is the control end for installing structures such as the power unit). A pitching unit articulated support 6 is fixed to the side wall or bottom plate of the installation groove 9 by welding or the like. The setting of the installation groove 9 makes the pitching unit articulated support 6 sink downward, and the pitching unit articulated support 6 is lower than the upper surface of the chassis body for connecting the pitching unit 7. The pitching unit 7 is used to connect with the drilling rig. The setting of the pitching unit articulated support 6 reduces the space occupied by the pitching unit 7 on the upper surface of the chassis body, so as to reduce the height of the main module when the machine is folded. While ensuring that the overall height of the shaft drilling rig meets the requirements of walking in the underground mine tunnel, it can also adaptably increase the specifications of the main module (excavation diameter of more than 3 meters) to improve its walking ability, without the need for repeated disassembly, transportation, and reassembly, thereby reducing costs.

[0031] It is understandable that the pitch unit 7 is a hydraulic telescopic structure such as a hydraulic cylinder, a hydraulic jack, etc., which can be selected according to actual needs, and no excessive restrictions are made here.

[0032] The working end face of the chassis body is fixed with a propulsion system assembly hinged support 5 by welding or the like, for connecting a base connecting plate of the propulsion system assembly of the drilling machine, and is connected with the propulsion system assembly of the drilling machine through the base connecting plate, and is used in cooperation with the pitching unit 7, and can be used for the stand-by machine and the receiver of the main machine module.

[0033] The control end of the chassis body is provided with a power unit assembly mounting area, which is provided with a plurality of rows of bolt connecting holes, and supports and connects the power unit assembly in a seat type structure, can effectively bear the overall weight of the power unit assembly, and the connection mode of multiple rows of bolts ensures the stability of the connection with the power unit assembly.

[0034] As shown in Fig. 2 The upper surface of the vertical beam of the chassis body is also fixed with a plurality of groups of inclined support assembly hinged supports 8, which are arranged at intervals along the length direction of the chassis body, and the inclined support assembly hinged supports 8 are located on the side away from the propulsion system assembly hinged support 5 of the pitching unit hinged support 6, and in this embodiment, two groups are provided, each containing two oppositely arranged inclined support assembly hinged supports 8, for connection with the inclined support assembly, which is a telescopic adjustable inclined rod structure, and is used for connection with the propulsion system assembly to support the propulsion system assembly when inclined hole excavation is performed, to ensure the stability of the propulsion system assembly and realize multi-angle adjustment of the inclination of the propulsion system assembly.

[0035] In this embodiment, a plurality of groups of inclined support assembly hinged supports 8 are arranged at intervals along the length direction of the chassis body, for adjusting the connection position of the inclined support assembly with the chassis body, to meet the demand for large-angle adjustment of the propulsion system assembly, and when small-angle adjustment is required, only the length of the inclined support assembly needs to be adjusted, the angle adjustment range is wider, and the adaptability is stronger.

[0036] The self-propelled large-diameter raise borer special track chassis in this embodiment adopts intensive and compact design, greatly increases the working capacity and automation degree of the drilling machine without increasing the external dimensions (height and width), realizes the self-propelled moving and transfer function of the raise borer, does not need any disassembly, reassembly, traction and towing, and the whole raise borer can reach the construction position automatically, and can directly start construction; after the construction is completed, it can automatically move to the next construction position, and the labor is freed from heavy physical labor, greatly improving the automation degree of the drilling machine.
