Problems solved by technology

Its disadvantages are: when the empty car is started, because each roller is in contact with the belt, the frictional resistance is large, resulting in a large starting current; The number of transfers of the belt conveyor is large, and multiple belt conveyors need to be linked to work. Due to the long chain start time and cumbersome operation, in the actual work process, the belt conveyor will not stop for 24 hours when the operation is intermittent, so there is a long time for the belt conveyor. Running in no-load state, all the rollers and belts always rub against each other, which increases the wear of belts and rollers and reduces the service life

[0023] refer to figure 1 , image 3 Make the invention. The energy-saving belt conveyor with automatic adjustment of idler height includes frame 1, motor 2, belt 5, driving wheel 3, driven wheel 4, load-bearing bracket 7 and idler 6, motor 2 is fixed on frame 1, frame 1 The two ends of the belt are respectively provided with a driving wheel 3 and a driven wheel 4, the motor 2 is connected with the driving wheel 3, and the two ends of the belt 5 for transporting materials are set on the driving wheel 3 and the driven wheel 4, and the driving wheel 3 and the driven wheel 4 The frame 1 between is provided with a plurality of load-bearing brackets 7, and each load-bearing bracket 7 is provided with a roller 6, and it is characterized in that: a lifting device 8 is set on the frame 1 at a distance of 2 load-bearing brackets 7, The top of each lifting device 8 is connected with the corresponding load-bearing bracket 7, and the lifting range of the lifting device 8 is to ensure tha...

Embodiment 3

[0026] As an improvement, the lifting device 8 can be a pneumatic lifting device. The pneumatic lifting device consists of a cylinder, a piston head, an air pump and a control box. The air pump and the control box are all arranged on the frame. The bottom is fixed on the frame by bolts, the air pump is connected to the cylinder through the corresponding pipeline, the control box is connected to the air pump, the piston head of the cylinder is on the bottom of the corresponding load-bearing bracket, and the maximum extension distance of the piston head ensures two lifts The lifting height of the lowest point in the middle of the belt between the devices shall prevail within the range of 5-50 mm. In the no-load state, the control box controls the air pump to operate the cylinder, so that the piston head extends to the maximum height; when there is a load, the control box controls the air pump to operate the cylinder, so that the piston head retracts to the minimum to ensure that ...

Abstract

The invention discloses an energy-saving belt conveyor with automatic adjustment of the height of the supporting roller, which comprises a frame, a motor, a belt, a driving wheel, a driven wheel, a load-bearing bracket and a supporting roller, and the two ends of the frame are respectively provided with a driving wheel and a driven wheel for transporting materials. The two ends of the belt are sleeved on the driving wheel and the driven wheel, and a plurality of load-bearing brackets are arranged on the frame between the driving wheel and the driven wheel, and each load-bearing bracket is equipped with idlers, which is characterized in that: A lifting device is installed on the frame at a distance of 1-3 load-bearing brackets. The upper part of each lifting device is connected to the corresponding load-bearing bracket. The lifting height shall prevail within the range of 5-50 mm. The energy-saving belt conveyor with automatic adjustment of the height of the idler rollers has only a few idler rollers running in contact with the belt under no-load conditions, which reduces the wear of the idler rollers and the belt, prolongs the service life of the belt, saves energy and reduces consumption, and reduces operating costs.

Description

technical field [0001] The invention relates to an improvement of a belt conveyor, in particular to an energy-saving belt conveyor with automatic height adjustment of supporting rollers, which is suitable for material transportation in industries such as metallurgy, ports, mines, and coal. Background technique [0002] The current material belt conveyors are all designed according to the national standard TD75, DTⅡ and DTⅡA standards, including the frame, motor, belt, driving wheel, driven wheel, load-bearing bracket and idler roller. The motor is fixed on the frame.
