Description

Technical Field

[0001] The utility model relates to the technical field of mine stone cutters, in particular to a high-flexibility mine stone cutter.

Background Art

[0002] A mine stone cutter, also known as a sawing machine or a stone cutting machine, is a device for directly mining stones on barren mountains, which is used to replace the extensive mining method combining traditional fire burning and blasting, reduce the damage to the mountain body, and greatly improve the utilization rate of stones. The mine stone cutter can directly cut square materials or plates on the mine, save resources and reduce environmental damage, having both economic benefits and social benefits.

[0003] For example, as Figure 1 shown, the prior art CN104071538B discloses a carrying mechanism, including a chassis 201, a first transverse moving wheel 202, and a second transverse moving wheel 203; the first transverse moving wheel 202 is the driving end, the second transverse moving wheel 203 is the driven end, and the driving shaft of the first transverse moving wheel 202 and the driven shaft of the second transverse moving wheel 203 are fixedly connected through a connecting flange 204. Since the working environment of the mine stone cutter is harsh and the walking road track is mostly rough and uneven, bumps and vibrations are inevitable. However, the connecting flange 204 rigidly connects the driving shaft and the driven shaft. After long-term operation, the driving shaft and the driven shaft are prone to dislocation, not on the same axis, resulting in imbalance of the driving shaft and the driven shaft and having the risk of fracture.

[0004] In view of this, this case conducts in-depth research on the above problems, and thus this case is generated.

Content of the Utility Model

[0005] The utility model aims to solve the technical problem that the driving shaft and the driven shaft of the mine stone cutter in the prior art are rigidly connected and are prone to dislocation and fracture, and provides a high-flexibility mine stone cutter, which uses a double-row chain device to connect the driving shaft and the driven shaft together, improves flexibility and reduces rigidity while ensuring connection stability, the driving shaft and the driven shaft are not easy to break, and thus the service life is improved.

[0006] The utility model is realized as follows: a high-flexibility mine stone cutter, including a driving walking device and a driven walking device, the driving walking device includes a driving shaft, and the driven walking device includes a driven shaft; the driving shaft and the driven shaft are connected through a double-row chain device.

[0007] Furthermore, the double-row chain device includes a first chain, a second chain, a driving sprocket, and a driven sprocket; the first chain and the second chain are fixedly connected side by side, the driving sprocket is sleeved outside the driving shaft, the first chain is chain-drivenly connected with the driving sprocket, the driven sprocket is sleeved outside the driven shaft, and the second chain is chain-drivenly connected with the driven sprocket.

[0008] Further, a first through hole and a second through hole which are communicated are formed in the driving sprocket. The aperture of the first through hole is smaller than that of the second through hole and a first step is formed. A first limiting step is formed on the outer surface of the driving shaft. The first through hole of the driving sprocket is sleeved outside the driving shaft and abuts against the first limiting step. The double-row chain device further includes a coupling lock plate which is installed in the second through hole and abuts against the first step, and also includes a locking screw for locking the coupling lock plate to the driving shaft.

[0009] Further, a first limiting protrusion is fixedly arranged outside the driving shaft, and a first limiting groove matched with the first limiting protrusion is formed on the inner wall of the first through hole.

[0010] Further, a second limiting step is formed on the outer surface of the driven shaft. The driven sprocket is sleeved outside the driven shaft and abuts against the second limiting step. A second limiting protrusion is arranged on the connecting surface between the driven shaft and the driven sprocket, and a second limiting groove matched with the second limiting protrusion is formed on the inner wall of the driven sprocket.

[0011] Further, a dust cover for sealing the double-row chain device is further included.

[0012] The advantages of the utility model are as follows:

[0013] 1. The rock cutting machine of the utility model uses a double-row chain device to connect the driving shaft and the driven shaft together. This flexible connection method allows the driving shaft and the driven shaft not to be on the same axis, improves the flexibility and reduces the rigidity while ensuring the connection stability, making the driving shaft and the driven shaft not easy to break, and thus improving the service life.

[0015] 3. By installing a coupling lock plate in the second through hole and locking it with a locking screw, the coupling lock plate and the first limiting step cooperate to axially limit the driving sprocket to prevent sliding. By designing the cooperation of the first limiting protrusion and the first limiting groove, it is ensured that the driving sprocket and the driving shaft can rotate synchronously to avoid relative rotation.

It is only for the convenience of describing these embodiments and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. In addition, terms such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first", "second", etc. may explicitly or implicitly include one or more of such features.

[0033] Please refer to Figures 2 to 10 As shown, the present utility model provides a highly flexible mine stone cutter 100, which includes a driving traveling device 1 and a driven traveling device 2. The driving traveling device 1 includes a driving shaft 11, and the driven traveling device 2 includes a driven shaft 21; the driving shaft 11 and the driven shaft 21 are connected by a double-row chain device 3.

[0034] In the highly flexible mine stone cutter 100 of the present utility model, the driving shaft 11 and the driven shaft 21 are connected together by the double-row chain device 3. This flexible connection method allows the driving shaft 11 and the driven shaft 21 not to be on the same axis, improving flexibility and reducing rigidity while ensuring connection stability, reducing the impact of bumpy roads on the driving shaft 11 and the driven shaft 21, making the driving shaft 11 and the driven shaft 21 not easily break, and thus increasing the service life.

[0035] Preferably, the double-row chain device 3 includes a first chain 31, a second chain 32, a driving sprocket 33, and a driven sprocket 34; the first chain 31 and the second chain 32 are fixedly connected in parallel. The driving sprocket 33 is sleeved outside the driving shaft 11, the first chain 31 is in chain drive connection with the driving sprocket 33, the driven sprocket 34 is sleeved outside the driven shaft 21, and the second chain 32 is in chain drive connection with the driven sprocket 34. Chain teeth that cooperate with the first chain 31 and the second chain 32 are formed outside both the driving sprocket 33 and the driven sprocket 34; the double-row chain formed by the first chain 31 and the second chain 32 is a prior art and will not be elaborated here. The connection methods of the first chain 31 with the driving sprocket 33 and the second chain 32 with the driven sprocket 34 both use chain drive. There will be no elastic sliding or slipping between the chain and the sprocket, which is efficient and reliable and can work under harsh environmental conditions such as high temperature and oil contamination.

[0036] During operation, the driving shaft 11 drives the driving sprocket 33 to rotate. The driving sprocket 33 drives the driven shaft 21 to rotate synchronously through a double-row chain composed of a first chain 31 and a second chain 32. The connection mode of the double-row chain allows slight misalignment and torsion to occur when the driving shaft 11 and the driven shaft 21 rotate, improving the connection flexibility between the driving shaft 11 and the driven shaft 21 and reducing the connection rigidity.

[0037] Preferably, a first through hole 331 and a second through hole 332 communicating with each other are formed in the driving sprocket 33.

The first through hole 331 of the driving sprocket 33 is sleeved on the driving shaft 11 and abuts against the first limiting step 12; the double-row chain device 3 further includes a coupling lock piece 35. The coupling lock piece 35 is installed in the second through hole 332 and abuts against the first step 333, and further includes a locking screw 36 for locking the coupling lock piece 35 to the driving shaft 11. By installing the coupling lock piece 35 in the second through hole 332 and cooperating with the locking screw 36 to lock, the coupling lock piece 35 and the first limiting step 12 cooperate to axially limit the driving sprocket 33 to prevent sliding.

[0038] Preferably, a first limiting protrusion 13 is fixedly provided on the outer surface of the driving shaft 11, and a first limiting groove 334 mating with the first limiting protrusion 13 is formed on the inner wall of the first through hole 331.

[0039] Preferably, a second limiting step 22 is formed on the outer surface of the driven shaft 21. The driven sprocket 34 is sleeved on the driven shaft 21 and abuts against the second limiting step 22. A second limiting protrusion 23 is provided on the connection surface between the driven shaft 21 and the driven sprocket 34, and a second limiting groove 341 mating with the second limiting protrusion 23 is formed on the inner wall of the driven sprocket 34. By designing the cooperation between the second limiting protrusion 23 and the second limiting groove 341, it is ensured that the driven sprocket 34 and the driven shaft 21 can rotate synchronously and relative rotation is avoided.
