CN-111731870-B - Sprocket adjusting device of double-bucket reclaimer

Abstract

The application discloses a chain wheel adjusting device of a double-bucket reclaimer, which comprises a chain wheel and a chain wheel base, wherein the chain wheel base is connected to a main support of a girder through a positive and negative screw rod. According to the chain wheel adjusting device of the double-bucket reclaimer, the fixed position and the structure of the chain wheel adjusting device of the double-bucket reclaimer are changed, the stress mode of the chain wheel base is changed, and the stress moment is reduced, so that the acting force of a welding point is reduced, the situation that the chain wheel base is pulled apart is reduced, the service life of equipment is prolonged, meanwhile, the front and back wire pipe fitting is more stable and convenient than the original screw rod nut in the aspect of adjusting the chain wheel, the production efficiency of the double-bucket reclaimer is improved, and the production is ensured.

Description

Sprocket adjusting device of double-bucket reclaimer Technical Field The application relates to the field of reclaimer equipment, in particular to a chain wheel adjusting device of a double-bucket reclaimer. Background The bucket wheel mechanism of the double-bucket reclaimer is driven by a chain transmission. The adjusting chain wheel is an indispensable part of the mechanism and is mainly used for adjusting the length of a chain to play a role in tensioning. As shown in fig. 1, the double-bucket reclaimer comprises a bucket wheel body 7, a transmission chain 5, a chain wheel 1, a chain wheel base 2, and a support 4 transversely manufactured on a girder 6 (a horizontal platform welded on the girder for supporting in general), wherein the chain wheel base 2 is fixed on the horizontal platform by a screw rod 8 and is adjusted by the screw rod 8 and a screw cap 9, but the chain wheel adjusting device is often cracked. Disclosure of Invention Aiming at the defects in the prior art, the application aims to provide a chain wheel adjusting device of a double-bucket reclaimer. In order to achieve the above purpose, the application provides a chain wheel adjusting device of a double-bucket reclaimer, which adopts the following technical scheme: the utility model provides a double-bucket reclaimer sprocket adjusting device, includes sprocket and sprocket base, the sprocket base passes through positive and negative silk lead screw to be connected on the main support of girder. Further, one end of the front and back screw rod is welded on one corner of the chain wheel base, and the other end of the front and back screw rod is welded on the main support of the girder. As another embodiment of the application, the main support is connected with a support, and the sprocket base and the support are connected through a positive and negative screw rod. Further, one end of the front and back screw rod is welded on one corner of the chain wheel base, and the other end of the front and back screw rod is welded on the support. Preferably, the stand is welded to the main support. Preferably, the support is made of iron plates. Compared with the prior art, the chain wheel adjusting device of the double-bucket reclaimer has the following effects: (1) According to the research on the stress structural form of the adjusting device, the fixed position and the structure of the chain wheel adjusting device of the double-bucket reclaimer are changed, the improved base is arranged on the main support of the double-bucket reclaimer along the stress direction, the stress mode of the chain wheel base is changed, and the stress moment is reduced, so that the acting force of a welding point is reduced, the occurrence of the situation that the chain wheel base is pulled apart is reduced, and the service life of equipment is prolonged; (2) The base is connected to the chain wheel and the support extending from the girder of the double-bucket reclaimer by the positive and negative screw rod, so that the base is reinforced, the platform deformation accident is prevented, meanwhile, the positive and negative screw pipe fitting is more stable and convenient in adjusting the chain wheel compared with the original screw rod and nut, the production efficiency of the double-bucket reclaimer is improved, the production is ensured, the adjustment is faster and more convenient, and the overhaul workload caused by the inconvenience of adjusting the chain wheel is reduced.
