Double-bucket reclaimer chain wheel adjusting device

Abstract

The application discloses a double-bucket reclaimer chain wheel adjusting device, which comprises a chain wheel and a chain wheel base, and the chain wheel base is connected to the main support of a girder through a forward and reverse screw rod. The double-bucket reclaimer chain wheel adjusting device changes the fixed position and structure of the double-bucket reclaimer chain wheel adjusting device, changes the stress mode of the chain wheel base, reduces the stress moment, thereby reducing the acting force of the welding point, reducing the occurrence of the chain wheel base being pulled apart, prolonging the service life of the equipment, and the forward and reverse screw pipe is more stable and convenient than the original screw rod nut in adjusting the chain wheel, the production efficiency of the double-bucket reclaimer is improved, and the production is ensured.

Description

Technical Field

[0001] This application relates to the field of material handling equipment, specifically to a sprocket adjustment device for a double bucket reclaimer. Background Technology

[0002] The bucket wheel mechanism of a double bucket reclaimer typically uses chain drive. Adjusting the sprocket is an essential part of this mechanism, primarily used to adjust the chain length and provide tension. For example... Figure 1 As shown, the double bucket reclaimer includes: bucket wheel body 7, transmission chain 5, sprocket 1 and sprocket base 2, and also includes a support 4 transversely made on the main beam 6 (generally a horizontal platform welded on the main beam for support). The sprocket base 2 is fixed to the horizontal platform by a screw 8 and is adjusted by the screw 8 and nut 9. However, the sprocket adjustment device often cracks. Summary of the Invention

[0003] In view of the above-mentioned shortcomings of the existing technology, the purpose of this application is to provide a sprocket adjustment device for a double bucket reclaimer.

[0004] To achieve the above objectives, this application provides a sprocket adjustment device for a double bucket reclaimer, which adopts the following technical solution:

[0005] A sprocket adjustment device for a double bucket reclaimer includes a sprocket and a sprocket base, wherein the sprocket base is connected to the main support of the main beam via positive and negative screws.

[0006] Furthermore, one end of the positive and negative lead screw is welded to one corner of the sprocket base, and the other end is welded to the main support of the beam.

[0007] In another embodiment of this application, a support is connected to the main support, and the sprocket base and the support are connected by a positive and negative screw rod.

[0008] Furthermore, one end of the positive and negative lead screw is welded to one corner of the sprocket base, and the other end is welded to the support.

[0009] Preferably, the support is welded to the main support.

[0010] Preferably, the support is made of iron plate.

[0011] Compared with the prior art, the sprocket adjustment device for the double bucket reclaimer of this application has the following advantages:

[0012] (1) From the perspective of the force structure of the adjustment device, by changing the fixed position and structure of the sprocket adjustment device of the double bucket reclaimer, the improved base is on the main support of the double bucket reclaimer along the force direction, which changes the force distribution mode of the sprocket base, reduces the force torque, thereby reducing the force of the welding point, reducing the occurrence of the sprocket base being pulled apart, and increasing the service life of the equipment.

[0013] (2) The base is connected to the sprocket and the support extending from the main beam of the double bucket reclaimer by using the positive and negative screws. This not only strengthens the base and prevents platform deformation accidents, but also makes adjusting the sprocket more stable and convenient than the original screw nut. This improves the production efficiency of the double bucket reclaimer, ensures production, and makes adjustment faster and more convenient, reducing the maintenance workload caused by the inconvenience of sprocket adjustment.
