Description

Technical Field

[0001] The utility model relates to the technical field of wire saw machines, in particular to a crawler type mine wire saw machine. Background Art

[0002] Mining wire saws are widely used in mining. Based on advanced sawing technology, they use a high-speed rotating wire rope to cut hard materials such as stone. Existing mining wire saws primarily consist of a drive unit, diamond beaded rope (or wire rope), a track system, a guide mechanism, and a control system. The drive unit provides high-speed rotational power to the diamond beaded rope, allowing it to cut along the guide mechanism mounted on the track. By precisely controlling cutting parameters (such as rotation speed and feed rate), mining wire saws achieve efficient and precise cutting.

[0003] Existing mining wire saws are all track-type wire saws. After the wire saw completes cutting a certain area, it must be hoisted from its original working position to a new one using lifting equipment. Before moving to the new working position, it takes a long time to lay the track smoothly. However, track splicing and laying is a physically demanding task, requiring at least two workers to lift the track. Furthermore, when cutting large areas continuously, the worker must constantly monitor the cutting progress and splice the track. This is time-consuming and labor-intensive, resulting in low production efficiency and numerous inconveniences for the user. Utility Model Content

[0004] In response to the above problems, the purpose of this utility model is to provide a crawler-type mining wire saw machine to solve the problems of the existing mining wire saw machine that requires frequent track splicing during large-area continuous cutting, which leads to time-consuming and labor-intensive, low production efficiency and inconvenience in use.

[0005] The utility model is achieved in this way:

[0006] A crawler type mining rope saw machine comprises a machine body and a machine head. A crawler walking device is provided at the bottom of the machine body. The machine head comprises a slewing device which is rotatably connected to the machine body. The slewing device comprises a slewing frame which is slidably connected to a lifting frame. A rope saw cutting device is provided on the lifting frame.

[0007] Furthermore, there are two crawler walking devices, which are symmetrically arranged on both sides of the fuselage.

[0008] Furthermore, the crawler walking device also includes a walking motor, which is fixed on the machine body. The output shaft of the walking motor is fixedly connected to the driving wheel. A plurality of supporting wheels are rotatably provided on the top of the support frame, and a plurality of supporting rollers are rotatably provided on the bottom of the support frame. The supporting wheels and the supporting rollers are all engaged and connected with the crawler track.

[0009] Furthermore, a U-shaped slide rail with an opening facing downward is fixedly provided on the top of the support frame, a nut is fixedly connected to one end of the U-shaped slide rail, a slider is slidingly passed through the U-shaped slide rail, a connecting frame is fixed to one end of the slider, the guide wheel is rotatably set on the connecting frame, and a screw is connected to the other end of the slider, which is passed through the nut and threadedly connected to it.

[0010] Furthermore, the rotating device includes a rotating reducer fixedly arranged at one end of the fuselage, and the output end of the rotating reducer is fixedly connected to the rotating frame.

[0011] Furthermore, the slewing frame includes a shaft sleeve and a rotating bracket. One end of the shaft sleeve is coaxially inserted into the slewing support of the slewing reducer, and the other end is fixedly connected to the rotating bracket. The rotating bracket is a C-shaped frame structure. Two sliding sleeves are vertically provided on the rotating bracket. A telescopic rod is also provided on the rotating bracket. The telescopic rod is arranged parallel to the two sliding sleeves.

[0014] Furthermore, it also includes a controller, which is connected to the crawler walking device, the rotating device, and the rope saw cutting device by signal.

[0015] The beneficial effects of the utility model are:

[0016] This new crawler-type mining wire saw machine can be used for continuous cutting of large areas simply by moving the crawler track, eliminating the need for manual track assembly. This saves time and effort, and improves cutting efficiency. Furthermore, when relocating within a site, the crawler track can now be used to move the machine freely, rather than requiring a crane or other lifting tool.

[0030] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] like Figures 1 to 7 The figure shows a crawler-type mining wire saw machine of the present invention, which includes a body 1 and a head 2. A crawler walking device 3 is provided at the bottom of the body 1. The head 2 includes a rotating device 21, which is rotatably connected to the body 1. The rotating device 21 includes a rotating frame 211, and a lifting frame 22 is slidably connected to the rotating frame 211. The lifting frame 22 is provided with a wire saw cutting device 23.

[0032] like Figures 2 to 4 As shown, a crawler track 3 is provided at the bottom of the fuselage 1. There are two crawler track 3, which are symmetrically arranged on both sides of the fuselage 1. A first protective cover 4 is provided above the crawler track 3. A plurality of lifting lugs 41 are fixedly provided on one side of the first protective cover 4. The lifting lugs 41 are fastened to the corresponding sides of the fuselage 1 via bolts (not shown in the figure). A second protective cover 11 is also provided on the fuselage 1. Cable brackets 12 are fixedly connected to both sides of the second protective cover 11. Preferably, the two cable brackets 12 are symmetrically arranged on both sides of the fuselage 1 for hanging external power cables and control cables to prevent them from being pressed by the crawler track 3. In addition, a door 13 is hinged at one end of the fuselage 1, so that the components inside the fuselage 1 can be inspected and repaired by closing the door 13.

[0033] Each crawler walking device 3 includes a support frame 31, one side of which is fixedly connected to the corresponding side of the fuselage 1. A drive wheel 32 and a guide wheel 33 are rotatably connected at each end of the support frame 31. Tracks 34 are sheathed around the outsides of the drive wheels 32 and guide wheels 33, and the tracks 34 are meshed with the drive wheels 32 and guide wheels 33. A U-shaped rail 35 with a downward-facing opening is also fixedly provided at the top of the support frame 31. A nut 351 is fixedly connected to one end of the U-shaped rail 35. A slider 352 is slidably inserted into the U-shaped rail 35. A connecting frame 353 is fixed to one end of the slider 352. The guide wheel 33 is rotatably mounted on the connecting frame 353. A screw 354 is connected to the other end of the slider 352. The screw 354 is inserted into the nut 351 and threadedly connected thereto. Each crawler walking device 3 also includes a walking motor 36, which is fixed on the fuselage 1. The output shaft of the walking motor 36 is fixedly connected to the driving wheel 32. A plurality of supporting wheels 37 are rotatably provided on the top of the support frame 31, and a plurality of supporting rollers 38 are rotatably provided on the bottom of the support frame 31. The supporting wheels 37 and the supporting rollers 38 are all engaged and connected with the crawler 34.

[0034] During operation, the travel motor 36 is started, and the output shaft of the travel motor 36 rotates, driving the drive wheel 32 fixedly connected thereto. The rotation of the drive wheel 32 then synchronously rotates the crawler track 34, the guide wheel 33, the supporting roller 37, and the supporting roller 38. The screw 354 is rotated to move the slider 352 within the U-shaped slide rail 35, thereby moving the connecting frame 353 fixedly connected to the slider 352, and further moving the guide wheel 33 on the connecting frame 353. In this way, the relative position between the guide wheel 33 and the drive wheel 32 can be freely adjusted according to the tightness of the crawler track 34, thereby tightening the crawler track 34.

[0035] like Figure 3 and Figure 5 As shown, the machine head 2 includes a rotating device 21, which is rotationally connected to the machine body 1. The rotating device 21 includes a rotating frame 211 and a rotating reducer 212 fixedly arranged at one end of the machine body 1, and the output end of the rotating reducer 212 is fixedly connected to the rotating frame 211. Among them, the rotating reducer 212 is a mature product currently sold on the market. It is a mechanical device that converts the movement of the input shaft into the rotation and deceleration of the output shaft. Its specific model is not limited here. The rotating reducer 212 uses a slewing bearing (commonly known as a turntable) as the reducer follower, which can achieve unlimited circular rotation and deceleration. Its specific working principle and structure will not be repeated here.

[0036] The slewing frame 211 includes a sleeve 2111 and a rotating bracket 2112. One end of the sleeve 2111 is coaxially fixedly inserted into the slewing bearing (not shown) of the slewing reducer 212, and the other end is fixedly connected to the rotating bracket 2112. The rotating bracket 2112 has a C-shaped frame structure. Two sliding sleeves 2113 are vertically mounted on the rotating bracket 2112. The rotating bracket 2112 is also provided with a telescopic rod 2114, which is arranged parallel to the two sliding sleeves 2113. The fixed end of the telescopic rod 2114 is fixedly connected to the rotating bracket 2112, and the movable end of the telescopic rod 2114 is fixedly connected to the lifting frame 22. The telescopic rod 2114 can be any of an electric telescopic rod 2114, a hydraulic cylinder, or a pneumatic cylinder, without limitation herein, and all fall within the scope of protection of the present utility model. Preferably, in this embodiment, a hydraulic cylinder is selected, and a hydraulic station (not shown in the figure) is provided on the machine head 2. The hydraulic station is mainly composed of key components such as a hydraulic pump, an oil tank, a hydraulic cylinder, a control valve and a control system. These components work together to provide power and control for the hydraulic cylinder, thereby controlling the extension and retraction of the hydraulic cylinder.

[0037] like Figure 6 and Figure 7 As shown, a lifting frame 22 is slidably connected to a rotating frame 211. Two sliding rods 221 are vertically mounted on the lifting frame 22. The two sliding rods 221 slide through two sliding sleeves 2113, respectively. A drive motor 222 is fixedly mounted on the lifting frame 22, with the output shaft of the drive motor 222 extending vertically downward. A wire saw cutting device 23 is mounted on the lifting frame 22. The wire saw cutting device 23 includes a main pulley 231 rotatably mounted at the bottom of the lifting frame 22. The main pulley 231 is fixedly connected to the output shaft of the drive motor 222. Two auxiliary wheels 232 are also rotatably mounted on the lifting frame 22. The two auxiliary wheels 232 are symmetrically arranged on either side of the main pulley 231 and serve as guides for the wire saw. A wire saw (not shown) is wound around the main pulley 231, the two auxiliary wheels 232, and the stone to be cut (not shown).

[0038] During operation, the slewing reducer 212 is activated, and the slewing bearing on the slewing reducer 212 drives the shaft sleeve 2111 and the rotating bracket 2112 to rotate synchronously, so that the slewing frame 211 and the machine head 2 are horizontal, vertical, or tilted. The telescopic rod 2114 is extended and retracted, thereby driving the lifting frame 22 and the wire saw cutting device 23 to slide back and forth along the sliding sleeve 2113. The drive motor 222 is activated, and the output shaft of the drive motor 222 rotates, driving the main pulley 231, which in turn drives the wire saw wrapped around the stone to be cut and the auxiliary pulley 232, thereby cutting the stone.

[0039] like Figure 1As shown, the head 2 is covered with a third protective cover 24 to protect the drive motor 222 and telescopic rod 2114 housed therein. A controller 5 is also included, which is signal-connected to the crawler travel device 3, the slewing device 21, and the wire rope saw cutting device 23. The controller 5 is located near the crawler-type mining wire rope saw machine. Specifically, the controller 5 includes a display screen 51 and operating buttons 52. In this embodiment, a PLC controller 5 is used. The operating buttons 52 can control the start and stop of the crawler travel device 3, the start and stop and slew angle of the slewing reducer 212 in the slewing device 21, and the start and stop of the drive motor 222 in the wire rope saw cutting device 23, as needed. The specific circuit connections and configurations are known in the art and fall outside the scope of this invention, and will not be detailed here.

[0040] When the crawler-type mining wire saw machine of the present invention needs to cut stone, the travel motor 36 is started, and the travel motor 36 rotates to drive the crawler travel device 3 to a specified position, and the rotary reducer 212 is started to drive the rotary frame 211 to rotate to a predetermined angle. The rotary frame 211 rotates to drive the lifting frame 22 and the wire saw cutting device 23 arranged thereon to rotate synchronously to a predetermined angle. The wire saw cutting device 23 can be horizontal, vertical or inclined. Then, the telescopic rod 2114 is started, and the telescopic rod 2114 is extended and retracted to drive the lifting frame 22 and the wire saw cutting device 23 arranged thereon to move to a specified height. Finally, the wire saw is wound around the main wheel disc 231, the auxiliary wheel 232 and the stone to be cut, and the drive motor 222 is started. The output shaft of the drive motor 222 rotates to drive the main wheel disc 231 to rotate, and then drives the wire saw wound around the stone to be cut, the main wheel disc 231 and the auxiliary wheel 232 to rotate, so as to cut the stone to be cut. As the stone cutting progresses, the position of the crawler walking device 3 is adjusted to achieve large-scale continuous cutting, eliminating the need for manual track splicing, saving time and effort and improving production efficiency. In addition, when transferring internally, the equipment, which previously could only be lifted by a crane or other lifting tools, can now be moved freely by the crawler walking device 3, which is convenient and fast.

[0041] Although the present invention discloses preferred specific embodiments to achieve the above-mentioned objectives, it is not intended to limit the structural features of the present invention. Any person skilled in the art should know that within the technical spirit of the present invention, any easily conceivable changes or modifications are possible and are all covered by the scope of the patent application of the present invention.
