Description

Technical Field

[0001] The utility model specifically relates to an adjustable drive installation device for an end-driven belt conveyor. Background Technique

[0002] Currently, the common drive methods for belt conveyors are intermediate drive and lower-end drive. For intermediate drive, the drive rollers are arranged in the middle position of the conveyor belt, and there are adjusting rollers for adjusting the deviation of the conveyor belt at both the upper and lower ends. For end drive, the drive rollers are installed at the upper or lower end of the conveyor, and there is a drive roller and a tensioning roller at the upper and lower ends respectively. The intermediate drive method has a complex equipment structure and a large volume, and is suitable for some larger conveying equipment. End drive has a simple structure and a compact volume, and is a common drive arrangement method at present.

[0003] For the drive rollers of existing conveyor end drives, deep groove ball bearings, tapered roller bearings, and spherical roller bearings are generally selected for installing bearings. These bearings cannot withstand large deflection angles. If the conveyor belt runs off track during normal operation, the drive rollers cannot adjust the deviation of the conveyor belt, and the installation accuracy requirements are relatively high during installation. If the bearings at both ends of the drive roller are not concentric, the bearings are easily worn. In addition, the current common transmission methods between the drive roller and the power equipment are belt drive or coupling drive. When the position of the drive roller changes, it is necessary to stop the machine to realign the transmission method, and the use effect is not good. Therefore, we propose an adjustable drive installation device for an end-driven belt conveyor. Content of the Utility Model

[0004] The purpose of the utility model is to provide an adjustable drive installation device for an end-driven belt conveyor, so as to solve the problems in the existing end-driven conveyor, that is, the drive rollers cannot adjust the deviation of the conveyor belt, the bearings at both ends of the drive roller are not concentric, the bearings are easily worn, and in addition, when the transmission method is misaligned, it is necessary to stop the machine for adjustment.

[0005] To achieve the above purpose, the utility model provides the following technical solution: an adjustable drive installation device for an end-driven belt conveyor, including:

[0006] A frame profile, on one side of which there is a movable mounting plate;

[0007] A bearing mounting block, which is fixed to the mounting plate through a detachable component;

[0008] A pillow block spherical roller bearing is arranged on one side of the bearing mounting block, and a connecting bolt matching with the bearing mounting block is arranged on the inner edge of the pillow block spherical roller bearing, and an outer spherical roller bearing is arranged inside the pillow block spherical roller bearing;

[0009] The conveyor drive roller is arranged on the other side of the bearing mounting block, and both ends of the conveyor drive roller are respectively matched with the spherical roller bearings with housings.

[0010] Preferably, the detachable component includes an upper clamping block and a lower clamping block. The upper clamping block is fixed to the top end of the mounting plate, and the lower clamping block is arranged at the lower end of one side wall of the mounting plate. The upper and lower surfaces of the bearing mounting block are respectively provided with connecting feet that are matched with the upper clamping block and the lower clamping block, and fixing bolts are arranged inside the connecting feet.

[0011] Preferably, the lower clamping block is in an "L" shape, and the lower clamping block is detachably connected to the mounting plate.

[0012] Preferably, a guiding bolt is arranged on the upper clamping block, and a first guiding chute corresponding to the guiding bolt is opened at the top end of the frame profile.

[0013] Preferably, an adjusting chute is opened on one side wall of the frame profile, a second slider is arranged inside the adjusting chute, and an adjusting bolt for pressing and fixing the mounting plate and the frame profile in cooperation with the second slider is arranged inside the mounting plate.

[0014] Preferably, six adjusting bolts are arranged.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] By arranging a mounting plate, spherical roller bearings with housings, spherical roller bearings and a bearing mounting block, this patent avoids the problem that traditional bearings cannot bear large deflection angles and cannot achieve real-time adjustment well. The device is easy to operate. By selecting spherical roller bearings that can bear large deflection angles, even when the two-side bearings are not concentric after adjustment at both ends of the conveyor drive roller, normal operation can still be achieved, reducing wear. In addition, through the connection and installation with multiple bolts, it is also convenient for disassembly and maintenance in the later stage, and the operation is simple. In addition, the connection with the external drive motor is changed to a universal joint coupling drive to ensure that the alignment of the drive mode can be carried out without stopping the machine.

[0024] Please refer to Figures 1-5 , the present utility model provides a technical solution: an adjustable drive installation device for an end-driven belt conveyor, including:

[0025] Frame profile 1, with a movable mounting plate 2 provided on one side of the frame profile 1, facilitating the later adjustment and movement of the position of the pillow block spherical roller bearing 5 to reduce eccentric wear;

[0026] Bearing mounting block 6, fixed to the mounting plate 2 through a detachable component;

[0027] Pillow block spherical roller bearing 5, provided on one side of the bearing mounting block 6, and a connecting bolt matching with the bearing mounting block 6 is provided on the inner edge of the pillow block spherical roller bearing 5. The inner side of the pillow block spherical roller bearing 5 has a spherical roller bearing, facilitating the bearing of a large deflection angle and ensuring the normal rotation of the conveyor drive roller 7;

[0028] Conveyor drive roller 7, provided on the other side of the bearing mounting block 6, and both ends of the conveyor drive roller 7 are respectively matched with the pillow block spherical roller bearing 5, facilitating the normal operation of the conveyor drive roller 7.

[0029] In this embodiment, preferably, the detachable component includes an upper clamp block 3 and a lower clamp block 4. The upper clamp block 3 is fixed to the top end of the mounting plate 2, the lower clamp block 4 is provided at the lower end of one side wall of the mounting plate 2, and connecting feet 601 matching with the upper clamp block 3 and the lower clamp block 4 are respectively provided on the upper and lower surfaces of the bearing mounting block 6. A fixing bolt is provided inside the connecting feet 601, facilitating the installation and fixation of the bearing mounting block 6.

[0030] In this embodiment, preferably, the lower clamp block 4 is in an "L" shape, and the lower clamp block 4 is detachably connected to the mounting plate 2, facilitating later disassembly and maintenance.

[0031] In this embodiment, preferably, a guiding bolt 301 is provided on the upper clamping block 3, and a first guiding sliding groove corresponding to the guiding bolt 301 is formed at the top end of the frame profile 1, facilitating the movement of the upper clamping block 3 and the mounting plate 2 along the frame profile 1.

[0032] In this embodiment, preferably, an adjusting sliding groove 101 is formed on one side wall of the frame profile 1. A second sliding block is arranged inside the adjusting sliding groove 101. An adjusting bolt 201 which is matched with the second sliding block to press and fix the mounting plate 2 to the frame profile 1 is arranged inside the mounting plate 2, facilitating the adjustment of the position of the mounting plate 2, so as to drive the conveyor driving roller 7 to slide up and down by sliding the mounting plate 2, and realizing the deviation adjustment of the conveyor belt on the conveyor driving roller 7.

[0033] In this embodiment, preferably, six adjusting bolts 201 are provided, facilitating connection and fixation.

[0034] The working principle and usage process of the present utility model: During use, the upper clamping block 3, the lower clamping block 4 and the bearing mounting block 6 form a C-shaped clamping bracket. The spherical roller bearing with housing 5 is fixed to the bearing mounting block 6 through a connecting bolt. The upper clamping block 3 and the lower clamping block 4 are fixed to the mounting plate 2. The mounting plate 2 is slidably mounted on the frame profile 1. Steps are designed at both ends of the conveyor driving roller 7, and the axial displacement of the conveyor driving roller 7 is restricted by abutting against the bearing mounting block 6 through the steps. The two ends of the conveyor driving roller 7 are matched with the spherical roller bearings inside the spherical roller bearing with housing 5, realizing the synchronous rotation of the bearing and the shaft. The mounting plate 2 can slide up and down on the frame profile 1, and the deviation adjustment of the conveyor belt at the ends of the conveyor driving roller 7 is realized by driving the conveyor driving roller 7 to slide up and down by sliding the mounting plate 2. Since the bearing adopts a spherical roller bearing capable of bearing large deflection angles, different distance adjustments at both ends of the conveyor driving roller 7 will not affect the service life of the bearing. In addition, the transmission mode between the conveyor driving roller 7 and the external driving motor is replaced with a universal joint coupling (not shown in the figure). Therefore, after the positions at both ends of the conveyor driving roller 7 are adjusted, it is not necessary to stop the machine to align the transmission mode again, realizing the real-time operation adjustment of the conveyor belt deviation.

[0035] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
