Problems solved by technology
[0002] At present, the single-roller drive cannot generate enough traction to meet the power transmission requirements of traditional belt conveyors
Therefore, double-drum or multi-drum driving separately is a common solution, but due to manufacturing and installation errors and factors such as uneven force on the conveyor belt of each driving drum, the load power of the motor will be unbalanced, seriously unbalanced or even burnt out. Therefore, double-drum or The power balance of multi-roller drives is particularly important
In the prior art, the performance test of the drum needs to be carried out through the joint action of the belt conveyor frame, belt, load motor, hydraulic system, belt deviation correction system, and belt tensioning system, and it is impossible to perform a double-drum or multi-drum power balance test

Embodiment Construction
[0027] The technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0028] figure 1 Schematic representation of the traditional permanent magnet drum power balance test device structure diagram. Such as figure 1 As shown, the traditional permanent magnet drum power balance test device can only perform power balance test on one permanent magnet drum or motor. It is not possible to perform a double-drum or multi-drum power balance test, nor is it possible to perform an overload start.
[0029] In order to solve the te...

The invention relates to a power balance and overload starting test device for a permanent magnet roller. The power balance and overload starting test device comprises a support, a brake unit supported on the support and used for braking the permanent magnet roller, and an analysis control unit connected with the brake unit and used for driving the brake unit to act and obtaining and analyzing the working power of the permanent magnet roller. A plurality of supporting parts used for supporting the permanent magnet roller are arranged on the support, every two supporting parts form a group, and the two supporting parts in one group are symmetrically arranged; the brake unit comprises a brake and a support rod for supporting the brake; the brake comprises a brake head and a brake disc which are used for braking the permanent magnet roller. According to the test device, power balance and overload starting tests can be carried out at the same time; the test is efficient and rapid, the problem of long balance time in the prior art is solved, and the purposes of reducing loss and prolonging the service life of the roller and the conveying belt are achieved; and the support can realize multi-roller test, so that the batch processing capacity is stronger, and the test efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of electric drive systems, in particular to a permanent magnet drum power balance and overload starting test device. Background technique [0002] At present, the single-roller drive cannot generate enough traction to meet the power transmission requirements of traditional belt conveyors. Therefore, driving double or multiple pulleys separately is a common solution, but due to factors such as manufacturing and installation errors and uneven force on the conveyor belt of each driving pulley, the load power of the motor will be unbalanced, seriously unbalanced or even burnt out. The power balance of multi-roller drives is particularly important. In the prior art, the performance test of the drum needs to be carried out through the joint action of the belt conveyor frame, belt, load motor, hydraulic system, belt deviation correction system, and belt tensioning system, and the power balance test of double or mu...
