Description

Technical field

[0001] The utility model relates to the technical field of mine stone cutters, in particular to a traveling mechanism of a mine stone cutter. [Background Technology]

[0002] A mining stone cutter, also known as a stone saw or stone cutting machine, is used to directly mine stone from barren mountains. It replaces the traditional extensive mining method of burning and blasting, reducing damage to the mountain and significantly improving stone utilization. A mining stone cutter can also cut square materials or slabs directly from the mine, saving resources and reducing environmental damage, resulting in both economic and social benefits.

[0003] For example, the prior art CN104071538B discloses a transport mechanism comprising a chassis, lateral moving wheels that move in the lateral direction, longitudinal moving wheels that move in the longitudinal direction, and two power devices that drive the lateral moving wheels and longitudinal moving wheels. Due to the dangerous working environment of the mine stone cutter, the road surface track is mostly rugged and uneven. After long-term operation, the lateral moving wheels and longitudinal moving wheels are often severely worn and need to be replaced frequently. Figure 1 As shown, both the lateral moving wheel and the longitudinal moving wheel adopt an integrated running wheel 200, which is sleeved on the output shaft 201 and locked with a screw 202. The carrying mechanism using the integrated running wheel 200 has the following technical defects:

[0004] 1. Once the integrated travel wheel is worn out, the entire wheel must be replaced, resulting in high replacement costs.

[0005] 2. The integrated travel wheel is sleeved on the outside of the output shaft through multiple bearings and other components. The mining stone cutter generates a large amount of lime impurities during cutting. The connection between the integrated travel wheel and the output shaft is contaminated with a large amount of lime, which reduces the lubricity and tightens the connection strength, making it inconvenient to remove the integrated travel wheel from the output shaft. Moreover, after replacing the new integrated travel wheel, it is necessary to readjust and clean the bearings and other components, and recalibrate the installation accuracy between the integrated travel wheel and the output shaft. Therefore, there are defects such as large replacement workload and low replacement efficiency.

[0006] In view of this, this case conducted an in-depth study on the above issues, which led to the emergence of this case. [Utility Model Content]

Therefore, the features defined as "first", "second" and the like can explicitly or implicitly include one or more of the features.

[0036] Figure 2 A carrying mechanism of a mine stone cutting machine is shown, which comprises a chassis 100 and a plurality of traveling mechanisms 101 mounted on the chassis, and the plurality of traveling mechanisms 101 drive the mine stone cutting machine to travel transversely or longitudinally respectively.

[0037] Please refer to Figures 3 to 10 The utility model provides a kind of traveling mechanism 101 of mine stone cutting machine, including gear shaft 1 and split traveling wheel 2 of sleeve setting in gear shaft 1 outer.

[0038] The traveling mechanism of the mining stone cutting machine of the present invention uses a split traveling wheel 2. After being damaged after long-term use, the split traveling wheel 2 does not need to be completely replaced, which saves costs. When replacing, the split traveling wheel 2 and the gear shaft 1 do not need to be disassembled, and there will be no inconvenience in disassembly due to contamination with lime. There is no need to recalibrate the accuracy, and the replacement speed is fast and the efficiency is high.

[0039] Preferably, the split travel wheel 2 includes a positioning sleeve 3 and a wheel body 4. A limiting step 11 is formed on the outer surface of the gear shaft 1. The positioning sleeve 3 is sleeved onto the outer surface of the gear shaft 1 and abuts against the limiting step 11. A connecting collar 31 is formed on the outer surface of the positioning sleeve 3. The wheel body 4 is sleeved onto the outer surface of the positioning sleeve 3 and secured to the connecting collar 31 via multiple hub screws 5. This design of the split travel wheel 2 allows only the wheel body 4 to be replaced, not the positioning sleeve 3, reducing replacement costs. The limiting step 11 on the outer surface of the gear shaft 1 ensures a consistent installation position between the split travel wheel 2 and the gear shaft 1, eliminating the need for recalibration of installation accuracy after replacement, reducing workload and increasing replacement efficiency. The connecting collar 31 is added to the outer surface of the positioning sleeve 3, with an outer diameter larger than that of the positioning sleeve 3. This increases the contact area between the positioning sleeve 3 and the wheel body 4, helping to enhance the stability of the connection between the positioning sleeve 3 and the wheel body 4. The wheel body 4 is locked on the connecting convex ring 31 by using a plurality of wheel hub screws 5. When replacing, the wheel body 4 can be removed by simply loosening the plurality of wheel hub screws 5. The wheel body 4 is easy to disassemble and install.

[0041] Preferably, as attached Figures 7-8 As shown, the wheel body 4 includes a main ring 41, a first wing ring 42, and a second wing ring 43. The first wing ring 42 is fixedly connected to the end of the main ring 41 facing the positioning sleeve 3, and the second wing ring 43 is fixedly connected to the end of the main ring 41 away from the positioning sleeve 3. The first wing ring 42, the main ring 41, and the second wing ring 43 are surrounded by a wheel body guide groove 44 for matching the wheel body 4 with the ground guide rail. The main ring 41, the first wing ring 42, and the second wing ring 43 are connected in a Y-shape, which reduces the material consumption of the wheel body 4 while ensuring the structural strength of the wheel body 4. The first wing ring 42 and the second wing ring 43 are connected to the main ring 41 at a certain inclination angle, which can increase the wrapping area of ​​the wheel body 4 on the ground guide rail, making the rolling smoother and more stable, and also reducing the probability of derailment.

[0042] Preferably, as shown in the accompanying drawings, the hub screw 5 is a tapered hub screw 5, which comprises a bolt segment 51, a tapered segment 52 and a screw rod segment 53 in sequence; the main body ring 41 is formed with a plurality of screw holes 45 matched with the tapered hub screw 5; the screw hole 45 comprises a bevel segment 451 and a cylindrical segment 452. Figures 8-9 The use of the tapered hub screw 5 has better fixing effect, can ensure that the wheel main body 4 remains stable under high-speed operation or bumpy road conditions, and reduces loosening caused by vibration or impact; the use of the tapered hub screw 5 can reduce the error during installation, and through the cooperation of the tapered segment 52 and the bevel segment 451, the tapered segment 52 plays a guiding role, so that the hub screw 5 can be more accurately installed to the correct position, avoiding safety hazards caused by improper installation.

[0043] Preferably, the split walking wheel 2 further comprises a locking component 6; the locking component 6 is threadedly connected with the gear shaft 1 and locked at the end of the positioning sleeve 3 away from the limiting step 11. The locking component 6 is used to firmly lock the positioning sleeve 3 on the gear shaft 1.

[0044] Preferably, in order to increase the locking stability, the locking component 6 comprises a first circular nut 61, a stop washer 62 and a second circular nut 63 arranged in sequence. The gear shaft 1 is formed with a second groove 13 on the outer surface at the connection with the locking component 6, and the inner wall of the stop washer 62 is formed with a clamping block 621 matched with the second groove 13.

[0045] Preferably, the gear shaft 1 is further sleeved with a floating oil seal 7, which plays a sealing role and avoids the entry of lime impurities into the walking mechanism 101.

[0046] Preferably, as shown in the accompanying drawings, the floating oil seal 7 is formed with at least one limiting groove 71 on the side facing the positioning sleeve 3, and the positioning sleeve 3 is formed with a limiting protrusion (not shown) fitted into the limiting groove 71 on the side facing the floating oil seal 7.
