Description

Technical Field

[0001] The utility model belongs to the technical field of crawlers, and in particular relates to a triangular crawler machine base of a disk saw machine. Background Art

[0002] When cutting hard materials, such as stone used in mining, a cutting device with a circular blade is commonly used. Typical examples of such cutting devices include band saws, chainsaws, rope saws, and circular saws. Circular saws feature two independently driven circular saw blades that simultaneously cut the stone. These dual circular saws have a traveling mechanism that drives the saws along a path defined by a pre-set track, efficiently cutting the stone on both parallel sides.

[0003] In the prior art, a fixed walking speed is set to allow the circular saw to cut the stone forward at a uniform speed; however, for stone, the hardness of the stone itself may vary at different locations; if the hardest part is cut, the circular saw needs to walk slowly, so that the cutting time is longer; if the part with lower hardness is cut, the walking speed can be increased to improve the cutting efficiency; compared with uniform cutting, the walking speed is adaptively adjusted according to the change in stone hardness, which can reduce the waste of electricity and improve cutting efficiency. The current prior art generally installs a movable wheel group at the bottom of the disc machine, but the traditional wheel group has problems with flexibility and poor terrain adaptability. Utility Model Content

[0004] The utility model discloses a triangular crawler machine base of a disc saw machine, which mainly solves the problems of poor flexibility and terrain adaptability of a traditional disc saw machine's traveling mechanism.

[0005] To achieve the above object, the utility model provides a triangular crawler machine base for a disc saw, comprising a chassis, drive devices symmetrically provided at both ends of the chassis, crawler wheels provided at the power output end of the drive device, and the crawler wheels comprising:

[0006] A driving wheel connected to the driving device via a transmission device;

[0008] The crawler track is movably mounted on the outside of the driving wheel and the guide wheel. Compared with traditional wheels, the crawler track has a larger contact area with the ground and lower pressure. It can travel stably in complex terrain such as mud, gravel, and bumps, avoiding slipping or getting stuck. It is especially suitable for the use of disc saws in outdoor construction scenes.

[0009] Preferably, the outer surface of the track is provided with an anti-skid structure along the length direction of the track, and the inner side of the track is provided with a guide structure along the length direction, the guide structure includes two rows of symmetrically distributed guide teeth, wherein the distance between the two rows of guide teeth is greater than the thickness of the guide wheel, and the anti-skid structure includes two rows of symmetrically distributed anti-slip blocks, the anti-slip blocks are in the shape of a quadrangular pyramid, and the bottom edge of the quadrangular pyramid is in contact with the outer surface of the track. The two rows of guide teeth on the inner side of the track cooperate with the guide wheel to accurately control the direction of the track, prevent deviation or derailment, and maintain the accuracy of the driving trajectory even on inclined or rugged roads. The anti-slip blocks on the outer side of the track increase the friction with the ground, especially on wet or rough ground, which can improve the grip. At the same time, the anti-slip blocks themselves have wear-resistant properties, reducing wear on the track surface.

[0012] Preferably, a second axle is rotatably mounted at the second mounting hole, with a track roller positioned at each end. This triangular arrangement (the drive wheel, guide wheel, and track rollers form a triangular support) enhances overall structural stability, reduces wobbling during travel, and ensures precision during operation of the circular saw. Multiple track rollers (e.g., six) are evenly distributed on the inner sides of the crawler tracks on both sides. This design distributes the weight of the circular saw across the crawler tracks, preventing local overload and extending the track life.

[0013] Preferably, the drive device is disposed above the mounting seat, and the mounting seat is detachably connected to the chassis via a first fixing bolt, wherein a side surface of the mounting seat is provided with a reinforcing rib, and a side surface of the mounting seat is further provided with a reinforcing member, and the reinforcing member is fixedly connected to the mounting seat.

The drive device adopts two motors, and the output ends are arranged relatively parallel, which can provide bidirectional driving force. Even if a single motor fails, basic driving can be maintained, thereby improving equipment reliability; at the same time, the dual motors in parallel can output greater torque to adapt to heavy-load conditions.

[0015] The transmission device includes a gearbox and a transmission, which can adjust the speed and torque according to ground conditions and operating requirements (such as reducing speed and increasing torque when climbing), improving the equipment's adaptability to different scenarios.

[0016] Preferably, the number of the second axles is three, and the second axles are parallel to each other and spaced apart.

[0017] Preferably, the guide teeth are in the shape of a quadrangular pyramid, the bottom surface of the quadrangular pyramid is connected to the inner side surface of the crawler track, and the guide wheel is rotatably arranged between the two rows of guide teeth.

[0018] The technical solution provided by the utility model has at least the following technical effects:

[0019] To enhance stability, the drive wheels are symmetrically located at each end of the chassis, bolted to the chassis via mounting brackets. Ribs on the side of the mounting brackets enhance structural rigidity.

This design balances torque output and prevents single-sided track slippage. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Example 1:

[0031] Please refer to Figure 1 as well as Figure 2 , Figure 1 This is a schematic diagram of the overall structure of Example 1 of the utility model. Figure 2 This is embodiment 1 of the utility model Figure 1 A partial enlarged schematic diagram of A; This embodiment provides a triangular crawler machine base, including a chassis 10, a driving device 20 is symmetrically provided at both ends of the chassis 10, and a crawler wheel is provided at the power output end of the driving device 20, and the crawler wheel includes:

[0032] A driving wheel 32, wherein the driving wheel 32 is connected to the driving device 20 via a transmission device;

[0033] A support frame 31 is fixedly connected to the chassis 10, wherein a rotation groove is opened on the inner side of the support frame 31, and guide wheels 34 are rotatably provided at both ends of the support frame 31;

[0034] The crawler belt 30 is movably mounted on the outside of the driving wheel 32 and the guide wheel 34 .

[0035] Please refer to Figure 3 , Figure 3 This is a structural diagram of the track wheel of an embodiment of the present utility model. The outer side of the track 30 is provided with anti-slip blocks 38 distributed in an array along the length direction of the track 30. The anti-slip blocks 38 on the outer side of the track 30 increase the friction with the ground, especially on wet or rough ground, which can improve the grip. At the same time, the anti-slip blocks 38 themselves have wear-resistant properties, which reduce the surface wear of the track 30.

[0036] Please refer to Figure 4 , Figure 4 This is a partial enlarged schematic diagram of the track wheel of Example 1 of the present utility model. Two rows of guide teeth 37 are linearly distributed along the length direction on the inner side of the track 30. The distance between the two rows of guide teeth 37 is greater than the thickness of the guide wheel 34. In this embodiment, the spacing between the two rows of guide teeth 37 arranged on the inner side of the track 30 is greater than the thickness of the guide wheel 34, so that the guide wheel 34 is embedded between the teeth, thereby limiting the lateral displacement of the track 30.

[0037] The support frame 31 is provided with a plurality of mounting holes, including a first mounting hole and a second mounting hole.

[0038] A first axle 33 is disposed at the center of the guide wheel 34 , and the first axle 33 is rotatably connected to the support frame 31 through a first mounting hole.

[0039] A second axle 35 is rotatably mounted at the second mounting hole, and a supporting wheel 36 is respectively provided at both ends of the second axle 35 .

[0040] The driving device 20 is arranged above the mounting seat 24, and the mounting seat 24 is detachably connected to the chassis 10 through a first fixing bolt 23, wherein a reinforcing rib 25 is provided on the side of the mounting seat 24, and a reinforcing rib 25 is provided on the side of the mounting seat 24. The support frame 31 is fixedly connected to the chassis 10, which enhances the deformation resistance of the overall structure, avoids loosening of components due to vibration, and ensures safety.

[0041] In this embodiment, the driving wheel 32 is connected to the driving shaft 321 via a second fixing bolt 322 .

[0042] The drive device 20 includes two motors, the output ends of the two motors are arranged relative to each other and in parallel, and the output ends of the motors are connected to a transmission device through a coupling 21. The transmission device includes a gearbox and a transmission 22. The transmission 22 is connected to the drive wheel 32 through a drive shaft 321. The drive wheel 32 is connected to the dual motors through the transmission 22. The torque and speed can be adjusted according to the working conditions (such as low speed and high torque to adapt to heavy-load cutting). Combined with the high friction of the crawler 30, power waste is avoided and traction efficiency is improved. The drive device 20 uses two motors with relatively parallel output ends, which can provide bidirectional driving force. Even if a single motor fails, basic driving can be maintained, thereby improving equipment reliability; at the same time, the dual motors in parallel can output greater torque to adapt to heavy-load conditions.

[0043] In this embodiment, there are four motors in total, which correspond to four track wheels respectively, and each motor provides power for one track wheel.

[0044] Each track wheel is driven by an independent motor, which can adjust the driving force of each wheel in real time according to the terrain (such as uneven roads, slopes, etc.), avoiding the power waste caused by unilateral slippage in traditional centralized drive and improving the passability on complex terrain.

[0045] The transmission device includes a gearbox and a transmission 22, which can adjust the speed and torque according to ground conditions and working requirements (such as reducing speed and increasing torque when climbing), thereby improving the adaptability of the equipment to different scenarios.

[0046] There are three second axles 35 , and the second axles 35 are arranged in parallel and at intervals.

[0047] The motion logic of this embodiment during operation is as follows:

[0048] Driving stage: the motor drives the driving wheel 32 to rotate, and the guide teeth 37 engage to drive the crawler 30 forward, and the supporting wheels 36 roll and support under the crawler 30.

[0049] Steering stage: the single-side motor slows down or reverses, the drive wheel 32 differentially rotates the crawler 30 to turn, and the guide wheel 34 assists in steering through the lateral force of the flange and the guide teeth 37.

[0050] Example 2:

[0051] Please Figure 5 , Figure 5 The schematic diagram of the structure of embodiment 2 of the present utility model, in this embodiment, a plurality of fixing holes are provided on the chassis 10, and the disc saw is fixedly connected to the chassis 10 through the fixing holes, thereby driving the movement of the disc saw through the track wheels.

[0052] The contact area between the crawler 30 and the ground is much larger than that of the wheel structure, which can greatly reduce the pressure on the ground (such as mud, sand and other soft ground), prevent the equipment from getting stuck, and is suitable for moving the disc saw on complex terrain such as unhardened construction sites, mountains or wetlands.

[0053] The anti-slip block 38 on the outside of the crawler track 30 increases the friction with the ground, and cooperates with the meshing structure of the inner guide teeth 37 and the guide wheel 34 to maintain a stable driving force even in wet, gravel or sloped scenes to avoid slipping (as mentioned in Example 1, the wear-resistant characteristics of the anti-slip block 38 reduce power waste).

[0054] The crawler 30 distributes the weight of the disc saw 40 to the entire contact surface of the crawler 30 through the supporting wheels 36, avoiding excessive force on a single point, and is suitable for bearing the heavy body of the disc saw 40 and the dynamic load during cutting.

[0055] In this embodiment, the crawler track 30 is made of rubber. The elastic structure of the crawler track 30 and the rolling support of the supporting wheel 36 can absorb bumps during driving, reduce equipment vibration, protect the internal precision components of the disc saw 40 (such as the cutting motor and control system), and at the same time improve the accuracy of the cutting operation (avoiding incision deviation due to vibration).

[0056] In this embodiment, four motors independently drive four track wheels, and the driving force of each wheel can be adjusted in real time through the electronic control system (such as deceleration or reversal of a single-side track 30), achieving small radius steering or even on-the-spot steering to adapt to narrow construction spaces.

[0057] The gearbox 22 in the drive device 20 can adjust the speed and torque according to the working requirements (such as reducing the speed and increasing the torque when climbing a slope), and cooperate with the high friction of the crawler 30 to avoid power waste and improve the heavy-load starting and continuous operation capabilities.

[0058] In this embodiment, the anti-sliding block 38, guide teeth 37 and drive wheel 32 of the crawler track 30 are all made of wear-resistant materials (such as high-strength rubber) to reduce wear during long-term driving; the rotating structure design of the supporting wheel 36 and the guide wheel 34 (such as mounting holes and wheel axles) is convenient for lubrication and replacement, reducing maintenance frequency.

[0059] In independent motor drive mode, if a single motor or track wheel fails, the other track wheels can still maintain basic movement of the equipment (dual motor redundancy design), improving construction continuity and reducing downtime losses.

[0060] The large ground contact area of ​​the crawler 30 can serve as a temporary support platform for the disc saw 40, especially when performing vertical cutting or tilting operations. By adjusting the support force of each crawler wheel (such as dynamically distributing torque), the machine body is kept balanced to avoid the risk of tipping.

[0061] When the disc saw 40 is cutting heavy materials (such as concrete and stone), the load on the machine body increases significantly. The strong traction and stability of the crawler 30 can ensure that the equipment moves smoothly under load without frequent stops to adjust the position.

[0062] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
