Due to their advantages such as large conveying capacity, simple structure, convenient maintenance, low cost, and strong versatility, they are widely used in industries and fields such as metallurgy, coal, and transportation.

[0003] In existing technologies, remote speed control usually uses frequency converters to change the speed of the motor to achieve remote speed control. However, the motor and the conveyor belt are usually rigidly connected, which results in a large impact during speed control, causing impact damage to the motor and the conveyor belt.

[0004] Therefore, a remote speed control device for multi-machine power balancing belt conveyors is needed to solve the above problems. Utility Model Content

[0014] Furthermore, a clutch assembly is provided between the conductor disk and the permanent disk. The clutch assembly includes a central shaft bolted to the side of the conductor disk, a sleeve sleeved to the outside of the central shaft, the sleeve bolted to the side of the center of the permanent disk, and a friction plate assembly provided between the central shaft and the sleeve.

[0015] Furthermore, the friction plate assembly abuts against the spring on one side, the other end of the spring abuts against the side of the central shaft, and the end of the sleeve near the central shaft is bolted to a retaining ring.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0029] like Figures 1-4 As shown, this utility model provides a remote speed control device for multi-machine power balancing belt conveyors, including a moving component 1 and a connecting component 2, wherein a clutch component 3 is provided in the connecting component 2.

[0030] The connecting component 2 includes a conductor disk 19 and a permanent disk 24, which are coaxially arranged. The moving component 1 controls the distance between the conductor disk 19 and the permanent disk 24.

[0031] The connecting component 2 is equipped with a clutch component 3, which is used to achieve a fixed connection between the conductor disk 19 and the permanent disk 24.

[0032] See Figure 2 The moving component 1 includes a base plate 11, with two slide rails 12 symmetrically arranged on the upper side of the base plate 11. Each slide rail 12 is provided with two sliders 13, and a slide plate 14 is provided on the slider 13. A drive motor 15 is fixedly installed on the slide plate 14. The drive motor 15 is used to drive the conveyor to rotate.

[0033] A servo motor 16 is fixedly mounted on the base plate 11. The servo motor 16 is connected to the lead screw 18 through the coupling 17. The lead screw 18 is threadedly connected to the lower side of the slide plate 14. The servo motor 16 drives the lead screw 18 to rotate through the coupling 17. The lead screw 18 drives the slide plate 14 to move along the slide rail 12, which is used to control the position of the drive motor 15.

[0034] See Figure 2 and Figure 3 The shaft of the drive motor 15 is fixedly connected to the conductor disk 19. A first end cover 191 is provided in the middle of the conductor disk 19 and is threadedly connected to the shaft. The first end cover 191 is used to fix the shaft and the conductor disk 19 axially. The conductor disk 19 and the shaft are circumferentially fixed by a key.

[0035] The connecting assembly 2 includes a permanent disk 24 arranged coaxially with the conductor disk 19. The permanent disk 24 is coaxially connected to the output shaft 21. The output shaft 21 is rotatably connected to the support plate 23 via the bearing seat 22. The support plate 23 is used to fix the output shaft 21 and the permanent disk 24. The output shaft 21 is used to drive the conveyor belt to rotate.

[0036] The end of the output shaft 21 is threadedly connected to the second end cover 25, which is located on the inner side of the permanent disk 24. A key bar is provided between the permanent disk 24 and the output shaft 21. The second end cover 25 is used to achieve axial fixation between the permanent disk 24 and the output shaft 21, and the key bar is used to achieve circumferential fixation between the permanent disk 24 and the output shaft 21.

[0037] See Figure 3 and Figure 4 A clutch assembly 3 is provided between the conductor disk 19 and the permanent disk 24. The clutch assembly 3 includes a central shaft 31 bolted to the side of the conductor disk 19, a sleeve 32 sleeved on the outside of the central shaft 31, and the sleeve 32 bolted to the side of the center of the permanent disk 24. A friction plate group 34 is provided between the central shaft 31 and the sleeve 32.

[0038] The friction plate assembly 34 abuts against the spring 33 on one side, and the other end of the spring 33 abuts against the side of the central shaft 31. The end of the sleeve 32 near the central shaft 31 is bolted to the retaining ring 321. The retaining ring 321 is used to hold the friction plate assembly 34 inside the sleeve 32. The spring 33 is used to compress the friction plate assembly 34 to achieve circumferential fixation between the central shaft 31 and the sleeve 32.

[0039] See Figure 4 The friction plate assembly 34 includes multiple alternating first friction plates 341 and second friction plates 342. The end of the spring 33 abuts against the first friction plate 341. Multiple inner sliders 3411 are evenly distributed on the inner side of the first friction plate 341. The inner sliders 3411 are slidably connected in the outer groove 311 outside the central shaft 31. The inner sliders 3411 and the outer groove 311 achieve circumferential fixation of the first friction plate 341 and the central shaft 31.

[0040] Multiple outer sliders 3421 are provided on the outer side of the second friction plate 342. The outer sliders 3421 are slidably connected in the inner sliding groove 322 axially provided on the inner side of the sleeve 32. The inner sliding groove 322 and the outer sliders 3421 realize the circumferential fixation of the sleeve 32 and the second friction plate 342.

[0041] See Figure 4 There are four inner sliders 3411, four outer slides 311, four inner slides 322, and four outer sliders 3421.

[0042] During operation, the initial state is that the conductor disk 19 and the permanent magnet disk 24 are disengaged. At this time, the sleeve 32 is at the rightmost end of the central shaft 31, and the spring 33 is disengaged from the friction plate assembly 34. There is no pressure between the first friction plate 341 and the second friction plate 342 in the friction plate assembly 34, and the first friction plate 341 and the second friction plate 342 can rotate relative to each other. The central shaft 31 and the sleeve 32 are also rotatable.

[0043] During operation, the drive motor 15 rotates, which in turn drives the conductor disk 19 to rotate. At this time, the conductor disk 19 does not drive the permanent disk 24 to rotate.

[0044] When speed change is required, the servo motor 16 drives the lead screw 18 to rotate. The lead screw 18 drives the slide plate 14, drive motor 15 and conductor disk 19 to approach the permanent disk 24. At this time, the conductor disk 19 drives the permanent disk 24 to rotate, and the permanent disk 24 drives the output shaft 21 to rotate.

[0045] The closer the conductor disk 19 and the permanent disk 24 are, the higher the rotational speed of the permanent disk 24 driven by the conductor disk 19.

[0046] When the conductor disk 19 and the permanent disk 24 overlap, the spring 33 is pressed against the friction plate group 34. At this time, the first friction plate 341 and the second friction plate 342 in the friction plate group 34 are circumferentially fixed. At this time, the central shaft 31 and the sleeve 32 are circumferentially fixed. Thus, the conductor disk 19 and the permanent disk 24 are circumferentially fixed, realizing stable power transmission between the conductor disk 19 and the permanent disk 24.

[0047] This invention enables a soft connection between the conductor disk 19 and the permanent disk 24, achieving stepless speed regulation of power and rotational speed, and reducing and buffering the impact caused by speed changes between the conductor disk 19 and the permanent disk 24. Simultaneously, the clutch assembly 3 is used to achieve a stable connection between the conductor disk 19 and the permanent disk 24, thereby ensuring stable power output from the output shaft 21.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
