Description

Technical field:

[0002] The utility model relates to a crawler type rope saw machine. Background technology:

[0004] The wire saw machine is a device for cutting mines, rough materials, curved plates, large stone slabs, thick concrete, irregular concrete reinforcement, etc. The wire saw machine needs to be moved during operation. At present, in order to facilitate the movement of the wire saw machine, a walking guide rail is usually laid on the site, and a walking wheel that can move on the walking guide rail is set at the bottom of the wire saw machine. For example, a wire saw machine for marble mining is disclosed in Chinese Patent Publication No. CN206416337U. However, this method of moving the wire saw machine through a guide rail has the following shortcomings:

[0005] (1) Before each operation, it takes a lot of time to lay the guide rails, then hoist the wire saw machine onto the guide rails, and finally adjust the position of the wire saw machine on the guide rails. The whole process takes a long time to adjust.

[0006] (2) When it is necessary to change the site for cutting at a short distance, it is still necessary to repeatedly lay the guide rails and hoist the wire saw machine, which makes the entire wire saw machine change site more troublesome.

[0007] Based on the above shortcomings, if the wire saw machine can have its own walking function without the help of guide rails, it will greatly improve the mobility of the wire saw machine and reduce the adjustment time before work. In view of this, this case was born. Utility model content:

[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0030] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0031] like Figures 1 to 8 As shown, the utility model is a crawler type wire saw machine, comprising a wire saw machine body 1, wherein a crawler wheel 2 for walking is arranged at both the left and right ends of the lower part of the wire saw machine body 1, and the crawler wheels 2 at the left and right ends of the lower part of the wire saw machine body 1 are respectively driven to rotate by a power assembly 3, that is, the two crawler wheels 2 are driven to rotate by different power assemblies 3. When working, each crawler wheel 2 is driven to rotate by the power assembly 3, and the walking function of the crawler wheel 2 is used to realize that the whole wire saw machine has the ability to walk autonomously, which is convenient to move and has good flexibility. When working, there is no need to spend a lot of time in advance to lay tracks, and the adjustment time of the wire saw machine before subsequent work is greatly reduced, and it is also convenient to change the site.

[0032] In this embodiment, the track wheel 2 includes a laterally arranged track bracket 4, and a track driving wheel 5 and a track guide wheel are respectively installed at the front and rear ends of the track bracket 4. A ring-shaped track 7 is wound between the track driving wheel 5 and the track guide wheel 6. The central axis of the track driving wheel 5 is connected to the power component, and the power component drives the track to rotate through the track driving wheel, and the track guide wheel guides the rotation of the track; a plurality of track bearing wheels 8 are arranged at intervals from front to back at the bottom of the track bracket 4, and the track bearing wheels 8 are in contact with the track 7. The plurality of track bearing wheels 8 are located between the track driving wheel 5 and the track guide wheel 6, and play a supporting role for the entire track wheel.

[0033] In this embodiment, a frame connecting plate 9 is fixed to the inner end of the crawler bracket 4, and the frame connecting plate 9 is connected to the frame side of the rope saw machine body 1 through fasteners to achieve the connection between the crawler wheel and the rope saw machine body.

[0034] In this embodiment, the power components of the two track wheels are completely identical in structure. Specifically, the power component 3 includes a power motor 10 arranged at the bottom of the frame of the rope saw machine body 1. The output shaft of the power motor 10 is connected to a reducer 11. The output shaft of the reducer 11 is connected to a transmission shaft 12. The transmission shaft 12 penetrates the frame of the rope saw machine body 1 laterally outward. The outer end of the transmission shaft 12 is connected to a planetary reducer 14 through a coupling 13. The track drive wheel 5 is locked on the rotating end of the planetary reducer 14, that is, the input shaft on the planetary reducer is the central axis of the track drive wheel. When working, the power motor is started, and the power output by the power motor is transmitted to the track drive wheel through the reducer, the transmission shaft, the coupling, and the planetary reducer in sequence, so that the track drive wheel rotates; and the track drive wheel drives the track to rotate.

[0035] In this embodiment, the power motor adopts a variable frequency motor.

[0036] In this embodiment, in order to prevent the upper end of the crawler track from being too long and thus bending downward, a support wheel 15 for supporting the crawler track is provided at the top of the crawler track bracket 4.

[0037] In this embodiment, a tension adjustment assembly 16 is provided inside the rear end of the track bracket 4, and the tension adjustment assembly 16 is used to adjust the position of the track guide wheel forward and backward to achieve tension adjustment of the track. Specifically: the tension adjustment assembly 16 includes an adjustment cylinder 17 and an adjustment frame 18 arranged in sequence from front to back, and the adjustment frame 18 is in a horizontal U-shape. The two sides of the adjustment frame 18 are respectively slidably matched with the transverse slide groove 19 of the inner wall of the rear end of the track bracket 4, and the track guide wheel 6 is installed on the inner side of the adjustment frame 18. The adjustment frame 18 moves synchronously with the track guide wheel 6; the adjustment cylinder 17 is arranged horizontally, and the end of the piston rod of the adjustment cylinder 17 is connected to the adjustment frame 18. When working, the adjustment cylinder piston rod is extended and retracted to drive the adjustment frame to move forward and backward, thereby achieving tension adjustment of the track.

[0038] In this embodiment, a support plate 20 is provided inside the crawler support 4, and a support sleeve 21 is provided on the support plate 20. The cylinder seat of the adjusting oil cylinder 17 slides through the support sleeve 21 in the transverse direction, and a return spring 22 that expands and contracts in the transverse direction is abutted between the support sleeve 21 and the rear end of the adjusting oil cylinder 17. The return spring 22 is sleeved on the outer side of the cylinder body of the adjusting oil cylinder 17. Since the adjustment oil cylinder, the adjustment frame and the crawler guide wheel form a whole, during the operation of the crawler wheel, when the crawler wheel rolls over a stone or a pit on the ground, the crawler guide wheel will move forward, and the crawler guide wheel drives the adjustment frame and the adjustment oil cylinder to move, and the return spring is compressed by the adjustment oil cylinder; when the crawler wheel returns to normal (on a plane) to operate, the return spring uses elastic force to push the adjustment oil cylinder, the adjustment frame and the crawler guide wheel to reset; at the same time, the return spring can play a proper buffering effect on the movement of the crawler guide wheel.

[0039] In this embodiment, in order to improve the protection effect, the upper end cover of the track wheel is provided with a track protection cover 23. Specifically, a plurality of protection cover fixing rods 24 are fixed to the outer end of the track bracket 4 (the end away from the wire saw machine body), and the plurality of protection cover fixing rods 24 are partially spaced apart in the lateral direction, and the protection cover fixing rods 24 are arranged longitudinally, and the end of the protection cover fixing rod 24 away from the wire saw machine body 1 is fixedly connected to the track protection cover 23, so as to play a fixing effect.

[0040] In another embodiment, the wire rope saw machine body may also be provided with an angle sensor, which is electrically connected to the power motors of the two track wheels through the control unit. The angle sensor is used to detect the left and right swing angles of the wire rope saw machine when it moves. When the angle sensor detects that the wire rope saw machine swings to the left or right, the control unit controls the power motors of the two track wheels to form differential rotation, so that the two track wheels rotate differentially during the driving process, thereby making the entire wire rope saw machine move in the opposite direction of the swing, realizing the swing adjustment, and ensuring that the wire rope saw machine moves in a straight line.

[0041] If the present invention discloses or involves components or structures that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connection using bolts or screws), and can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the mutual fixed connection can also be replaced by an integrated structure (for example, manufactured by one-piece molding using a casting process) (except where it is obviously impossible to use an one-piece molding process).

[0042] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in the above utility model include states or shapes that are approximate, similar or close thereto.

[0043] Any component provided by the utility model can be assembled from multiple separate components, or can be a separate component manufactured by an integrated molding process.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for protection of the utility model.
