Description

Technical Field

[0001] This utility model relates to a direct-drive transmission track mechanism for a wire saw, belonging to the field of wire saws. Background Technology

[0002] In engineering fields such as construction, mining, demolition, and rescue, wire saws are widely used as efficient cutting tools for cutting hard stone, concrete, and other solid materials. Traditional wire saws typically employ wheeled or rail-mounted mobile devices, which work well on flat ground. However, their mobility and adaptability are often limited in complex or uneven terrain, leading to reduced work efficiency or even malfunction.

[0003] In addition, existing wire saw machine transmission track mechanisms usually adopt an indirect drive method, that is, the motor transmits power to the drive wheel through a series of transmission components, thereby driving the track to move. However, this indirect drive method will result in increased energy loss and low transmission efficiency due to the setting of multiple transmission components. Furthermore, multiple transmission components will increase the difficulty and cost of equipment maintenance. When moving on complex terrain, it may cause poor contact between the track and the ground, which will affect the stability and passability of the equipment. Utility Model Content

The drive wheel drives the track to move in a cyclic motion along the support wheel and driven wheel, thereby realizing the movement of the wire saw.

[0006] Furthermore, the mobile device is also equipped with a track frame and support rollers. The support rollers are located on the opposite side of the support rollers and at the upper center of the track frame. The support rollers are evenly distributed below the track frame and spaced apart along the length of the track. The driven rollers are installed on the upper left side of the track frame.

[0007] Furthermore, the track frame is a frame structure, and the support rollers and driven rollers are mounted on the track frame by a detachable connection.

[0008] Furthermore, the track has several sets of inner teeth arranged side by side inside, with each set of inner teeth distributed at intervals along the width direction of the track.

[0009] Furthermore, the track has several sets of protrusions arranged side by side on its outer surface, with each set of protrusions spaced apart along the width of the track.

[0010] Furthermore, a cover plate is installed on the side of the reducer away from the drive wheel, and a bearing mounting seat is installed between the other side of the reducer and the drive wheel. The bearing mounting seat is connected to the reducer via a connecting flange.

[0011] Furthermore, bearings are respectively installed on the left and right sides of the bearing mounting base, and a spacer is provided between the two bearings. An end cap is also provided on the side of the bearing mounting base near the drive wheel.

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides a technical solution for a direct-drive transmission track mechanism for a wire saw: it includes: The mobile device 1 includes a track 11, a drive wheel 12, a driven wheel 13, and a support wheel 14. The drive wheel 12 is engaged with a groove on the inner side of the track 11, and the driven wheel 13 is provided on the opposite side of the drive wheel 12. The support wheels 14 are evenly distributed on the track 11. When the drive wheel 12 rotates, the track 11 is driven and performs a cyclical movement guided by the driven wheel 13 and the support wheel 14. The power unit 2 includes a motor 21 and a reducer 22. The motor 21 is connected to the reducer 22 via a connecting seat 23. The output power of the reducer 22 is connected to the drive wheel 12 via the reducer shaft 221. When the motor 21 outputs power, it is reduced in speed and increased in torque by the reducer 22, and then transmitted to the drive wheel 12 of the moving device 1. The drive wheel 12 drives the track 11 to move in a cycle along the support wheel 14 and the driven wheel 13, thereby realizing the movement of the wire saw.

[0020] To enhance the structural stability and support capacity of the track, the mobile device 1 is also provided with a track frame 15 and a support roller 16. The support roller 16 is located on the opposite side of the support roller 14 and at the center of the track frame 15. The support roller 14 is evenly distributed below the track frame 15 and is spaced apart along the length of the track 11. The driven wheel 13 is installed on the upper left of the track frame 15.

[0021] The combined use of the carrier roller 16 and the track roller 14 ensures the stability and reliability of the track 11 during operation, thereby improving the adaptability and passability of the equipment. The carrier roller 16 is located at the center above the track frame 15, which helps to balance the tension of the track 11, reduce the wear of the track 11, and extend the service life of the track 11.

[0022] To simplify the installation and maintenance process, the track frame 15 is a frame structure, and the support rollers 14 and driven rollers 13 are fixedly mounted on the track frame 15 by a detachable connection.

[0023] The track frame 15 with its frame structure provides support, while the detachable installation method simplifies the installation and maintenance process of the support rollers 14 and driven rollers 13, reduces maintenance time and costs, and improves the maintenance efficiency of the equipment. This design also facilitates the quick replacement of worn parts, reduces equipment downtime, and improves operational efficiency.

[0024] To enhance the traction and stability of the track, several sets of inner teeth are arranged side by side inside the track 11, with each set of inner teeth distributed at intervals along the width direction of the track 11.

[0025] To increase the friction between the track and the ground, several sets of protrusions are arranged side by side on the outside of the track 11, and the sets of protrusions are distributed at intervals along the width direction of the track 11.

[0026] The raised portion increases the friction between the track 11 and the ground, improves the traction and stability of the track 11, and effectively prevents the track from slipping. This design enables the track 11 to maintain good grip on various terrains, improving the passability and stability of the equipment.

[0027] To improve the stability and reliability of power transmission, a cover plate 26 is installed on the side of the reducer 22 away from the drive wheel 12, and a bearing mounting seat 25 is installed between the other side of the reducer 22 and the drive wheel 12. The bearing mounting seat 25 is connected to the reducer 22 through a connecting flange 24.

[0028] The design of the cover plate 26 and the bearing mounting seat 25 improves the stability and reliability of power transmission, ensures the correct positioning and stable operation of the reducer 22, reduces the impact of vibration and shock on the power unit 2, and also helps to protect the reducer 22 from external impacts and damage, thus improving the durability of the equipment.

[0029] To ensure stable support and precise positioning of the reducer shaft, bearings 251 are installed on the left and right sides of the bearing mounting base 25, and a spacer 252 is provided between the two bearings 251. An end cover 253 is also provided on the side of the bearing mounting base 25 near the drive wheel 12.

[0030] The end cap 253 further restricts axial movement, improves the stability and reliability of the power unit 2, and helps prevent dust and impurities from entering the bearing mounting seat 25, protecting the bearing 251 from contamination and extending the service life of the bearing 251.

[0031] To reduce axial movement, the drive wheel 12 is sleeved on the reducer shaft 221. The reducer shaft 221 passes through the end cover 253 and is supported by the bearing 251. An elastic retaining ring 27 for the shaft is also provided between the end cover 253 and the drive wheel 12.

[0032] This design ensures the continuity and stability of power transmission, improves transmission efficiency and equipment performance. The shaft elastic retaining ring 27 is used to limit the axial movement of the lip seal inside the equipment, ensuring good sealing performance. The bearing 251 relies on the end cover 253 to limit its axial movement, preventing relative displacement caused by vibration or impact, and improving the stability and reliability of the transmission system.

[0033] To provide more precise speed control, the motor 21 is a brushless DC motor or an AC servo motor, and the reducer 22 is a worm gear reducer.

[0034] Among them, brushless DC motors or AC servo motors can provide more precise speed control, while worm gear reducers can achieve high torque output and compact design. This combination not only improves transmission efficiency but also reduces energy consumption, improving the energy efficiency and operating performance of the equipment. The selection of equipment in power unit 2 enables the wire saw to maintain efficient and stable operation under various working conditions, improving operating efficiency and equipment adaptability.

[0035] Example 1: like Figure 1 As shown, the mobile device 1 of this application is located on the left and right sides of the bottom of the wire saw, and the power device 2 is located inside the wire saw. In the direct drive transmission track mechanism of the wire saw of this application, the coordinated work of the power device 2 and the mobile device 1 is the key to achieving efficient operation of the equipment.

[0036] First, the motor 21 serves as a power source, outputting power and transmitting it to the reducer 22. The gear system inside the reducer 22 reduces and increases the torque of the power. Through adjustment, the power meets the working requirements of the drive wheel 12. The processed power is transmitted to the bearing mounting seat 25 through the reducer shaft 221, and supported by the bearing 251 inside it to ensure smooth and efficient power transmission.

[0037] The bearing mounting seat 25 is connected to the reducer 22 via the connecting flange 24, ensuring the stability and precise alignment of the reducer 22. The end cover 253 and the shaft elastic retaining ring 27 further ensure the axial stability of the reducer shaft 221 and prevent it from shifting during operation.

[0038] Finally, power is transmitted to the drive wheel 12, and through the engagement of the drive wheel 12 with the track 11, the track 11 is driven to move along the path guided by the support roller 14 and the driven wheel 13.

[0039] The cyclic movement of the track 11 in this application enables the wire saw to move stably on various terrains while performing efficient cutting operations; the support rollers 14 are evenly distributed under the track frame 15, providing necessary support and reducing the contact pressure between the track and the ground, thereby improving the passability and stability of the equipment; the driven rollers 13 and the support rollers 16 are located at the upper left and upper center of the track frame 15, respectively, guiding the movement direction of the track 11 and assisting in tensioning, and ensuring the correct movement and stable operation of the track 11 during the movement process.

[0040] This application employs a tracked mobile device 1, which enables the wire saw to move stably in complex or uneven terrain conditions, providing better ground adhesion and stability. This design is particularly suitable for operating on irregular ground, improving the applicability and flexibility of the equipment.

[0041] This application adopts a direct-drive power unit 2, which directly drives the drive wheel 12 by outputting the power from the motor 21 and processing it through the reducer 22. This eliminates the multi-stage transmission components in the traditional indirect drive method, significantly reduces energy loss, and improves transmission efficiency. This design not only improves the cutting efficiency of the wire saw, but also successfully reduces energy consumption, maintenance difficulty, and cost.
