Description

Technical Field

[0001] The utility model relates to the field of combined rope saw machines, in particular to a driven wheel group of the combined rope saw machine which is easy to maintain. Background Art

[0002] The combined rope saw machine is large in size, with an overall size of up to 12m*6m*6.5m. Its large parts such as columns and wheel groups weigh more than several tons. In order to eliminate the problem of rope length deviation in the combined rope saw machine, the driven wheel group of the combined rope saw machine consists of a group of driven wheels installed on a through shaft. In addition, due to the large width of the driven wheel body and the large number of saw ropes loaded, the installation and matching of the driven wheel and the guide wheel shaft will be more difficult, and the load borne by the bearing will increase significantly, resulting in a certain limitation on the life of the driven wheel. The combined rope saw machine is generally After working for about 10,000 hours, the driven wheel or the driven wheel bearing needs to be replaced. When replacing, the entire wheel assembly needs to be removed from the assembly saw machine, and then the damaged driven wheel or driven wheel bearing needs to be taken out from the equipment, replaced and then reinstalled on the equipment, which ultimately leads to many replacement (maintenance) processes and a long time. During this period, the combination wire saw machine cannot work because the entire combination wire saw machine is disassembled, affecting normal production. In addition, when the combination wire saw machine is reassembled, its assembly accuracy must be guaranteed, which is difficult and greatly wastes manpower and material resources.

[0003] The prior art CN202311847670.2 discloses a multi-strand diamond wire saw guide wheel structure, including a guide wheel shaft inserted into the guide wheel body, with both ends of the guide wheel shaft supported by a guide wheel seat; two bearing seats are respectively installed on the end holes at both ends of the guide wheel body, and a bearing sleeve is provided between the bearing and the guide wheel shaft, which is axially positioned on the guide wheel shaft by a set screw; the outer circle of the bearing sleeve is tightly matched with the inner hole of the bearing, and the inner and outer ends of the inner ring of the bearing are respectively positioned by the bearing sleeve shoulder and locked by the locking nut; the outer circle of the bearing is tightly matched with the inner hole of the bearing seat, and the inner and outer ends of the outer ring of the bearing are respectively positioned by the inner hole stop of the bearing seat and pressed by the bearing cover. Although the invention ensures the installation accuracy by controlling the axial position of the bearing sleeve so that the bearing sleeve shoulder and the inner hole stop shoulder of the bearing seat are coplanar, the following problems still exist:

[0004] 1. Although the invention ensures good installation accuracy, it does not fundamentally simplify the replacement process of the driven wheel set. During maintenance, the entire wheel set needs to be disassembled, the damaged parts need to be separated and then replaced one by one. This process is complicated and time-consuming, affecting maintenance efficiency.

[0005] 2. Due to the large weight and volume of the driven wheel assembly, as well as its fixing method in the gang saw machine, the disassembly process is not only time-consuming and labor-intensive, but also requires the assistance of professional lifting equipment, which further increases the complexity and cost of maintenance. Utility Model Content

[0006] In view of this, the purpose of the utility model is to provide a driven wheel group for a combined rope saw machine that is easy to maintain. The driven wheel group can be clamped separately by the mounting seat and kept suspended horizontally, and it can still maintain balance even when the bearing seat is removed, thereby realizing the rapid disassembly, assembly and replacement of the transmission wheel on the driven wheel group, greatly simplifying the replacement process, reducing the complexity of maintenance, reducing dependence on professional lifting equipment, simplifying the maintenance process, and saving time and cost.

[0007] The technical solution adopted by the utility model to solve its technical problems is:

[0046] The working principle and use method of a driven wheel group of a combined wire saw machine that is easy to maintain in this embodiment:

[0047] The present embodiment provides a driven wheel assembly of a combined wire saw machine that is easy to maintain. The driven wheel assembly 2 is fixed to the main body 1 through the mounting seats 3 and the bearing seats 4 at both ends. The structural design of the main body 1 includes a main mounting frame 11 and a transition mounting frame 12. The transition mounting frame 12 is a detachable connecting component that allows quick adjustment and maintenance operations. The mounting seat 3 and the locking pressure block 32 are designed to ensure that the driven wheel is firmly clamped, so that the driven wheel assembly 2 can still be kept horizontally suspended after the bearing seat 4 is removed without the assistance of lifting equipment, thereby realizing the rapid disassembly and replacement of the transmission wheel on the driven wheel assembly 2, simplifying the maintenance process, saving time and cost; the groove 311 of the seat body 31 cooperates with the locking pressure block 32 to The rotating shaft 21 at the end of the driven wheel group 2 is clamped and fixed, and a limiting screw 321 is arranged on the circumferential surface of the locking pressure block 32 to cooperate with the limiting groove 211 on the rotating shaft 21 to realize the limiting fixation of the rotating shaft 21 and ensure the stable operation of the driven wheel group 2. A through hole 51 and an adjustment tightening screw 52 are arranged on the cover plate 5 of the mounting seat 3 away from the transmission wheel end, which allows fine-tuning of the axial position of the rotating shaft 21, facilitates precise adjustment on site, and improves maintenance efficiency; the size design of the transition mounting frame 12 ensures sufficient space to accommodate the disassembly of the driven wheel, avoids space limitations, optimizes the operating environment during maintenance, improves the flexibility of maintenance, makes maintenance work smoother, and speeds up the overall maintenance process.

[0048] When in use, first assemble the main mounting frame 11 and the transition mounting frame 12 of the main body 1 to ensure that the two are stably connected through the designed detachable connection point; then fix the seat body 31 of the mounting seat 3 on the mounting plate 111 through a nut, then install the bearing seat 4 corresponding to the mounting seat 3 on the specified position of the transition mounting frame 12 and fix it through a nut, and then use the lifting equipment to lift the assembled driven wheel group 2, and clamp the rotating shaft 21 at one end of the driven wheel group 2 between the groove 311 and the locking block 32, and insert the other end into the sleeve 41 of the bearing seat 4, and then use the limiting screw 321 and the limiting groove 211, as well as the limiting rod 411 and the positioning groove to limit the rotating shaft 21 on the mounting seat 3 and the bearing seat 4 respectively. To prevent the rotating shaft 21 from deflecting, the axial position of the rotating shaft 21 is adjusted by the cooperation of the tightening screw 52 and the adjusting bolt, so that the driven wheel group 2 can accurately correspond to the driving wheel group of the combined rope saw machine, and finally the locking pressure block 32 is completely tightened to complete the installation of the driven wheel group 2. When the transmission wheel needs to be replaced, the connecting nut between the transition mounting frame 12 and the main mounting frame 11 is removed, so that the bearing seat 4 is pulled out axially along the rotating shaft 21 along the transition mounting frame 12. At this time, the driven wheel group 2 can still remain horizontally suspended with the support of the mounting seat 3. The transmission wheel to be replaced is taken out from one end of the bearing seat 4 and replaced. After the replacement is completed, the bearing seat 4 and the transition mounting frame 12 are installed back to their original positions, thereby completing the replacement of the transmission wheel.
