　　2、 Installation of 2JPB-7.5 ore winch

　　Due to frequent relocation during on-site use of the rake winch, concrete foundations are generally not poured. Practice has proven that the quality of temporary installation directly affects the efficiency and lifespan of the winch. The user department must not take this lightly.

　　The commonly used temporary installation methods can be summarized as follows:,

　　When the roof of the mining area is low, it is simple and easy to fix the winch with wooden pillars; When the roof of the mining area is high, wooden pillars are still used, although it is unsafe. For this purpose, it can be fixed by tightening the rear of the winch base with a steel wire rope. But both methods have their shortcomings. The former has certain limitations in use due to the height of the roof. The latter has two difficult to overcome problems: 1. If there is a high accumulation of minerals in front of the winch or the position of the guide pulley is too high, the winch will bounce and cause damage to the equipment during use. The base is easily damaged by steel wire ropes.

　　Based on the appeal reasons, the screw support fixation method can be considered

　　3、 Structure of 2JPB-7.5 ore winch

　　The 2JPB-7.5 ore winch consists of a reduction device, a main drum, an auxiliary drum, a control device, a steel rope guide device, and an electric motor. These components are installed inside and outside the shell, which is a component with good rigidity, providing protection, support, and bearing all loads. It is fixed on the root slide connected to the foundation with bolts. The double drum winch has a main drum (installed on the right side, close to the motor) and a secondary drum (installed on the left side). The three drum winch has one main drum (installed in the middle) and two auxiliary drums (installed on the left and right). The three drum winch can also be equipped with two main drums (installed on the right and middle sides) and one auxiliary drum (installed on the left side), each of which has a corresponding control device and a steel rope guide device.
