Embodiment 1

[0081] Such as figure 1 As shown, it is a schematic flowchart of a method for detecting the braking capability of a brake provided by Embodiment 1 of the present invention. The method can be as follows.

[0082] Step 101: Detect the state information of the brake.

[0083] Wherein, the state information of the brake includes static characteristic information of the brake and dynamic characteristic information of the brake.

[0084] In step 101, because the brake safety detection system in the crane includes two parts: one part is the brake detection circuit, which is responsible for detecting the status information of the brake; , Send an alarm to protect the safety of the crane work.

[0085] The brake detection circuit is responsible for two aspects of detection: on the one hand, it detects the brake debugging status, that is, the static characteristic information of the brake; on the other hand, it detects the state information of the brake during braking, that is, the d...

Abstract

The invention discloses a method and device for detecting the braking capability of a brake. The method comprises the step of detecting the state information of the brake, the step of determining the braking capability of the brake according to the state information and the step of executing a braking protection strategy when the braking capability of the brake is lower than the set theoretical braking capability. The situation that the braking capability of the brake is lower than the set theoretical braking capability is found in time by detecting the state information of the brake, the protection measure is taken for the situation, and therefore the safety accidents caused by sudden failure of the brake or the insufficient braking capability are prevented, the problems that the brake cannot be braked due to reduction of the braking capability, the glide hook phenomenon in the engineering field happens, the construction safety is seriously affected, and the construction safety coefficient is reduced are solved, and the safety performance of construction is improved.

Description

technical field [0001] The invention relates to the technical field of construction machinery control, in particular to a method and equipment for detecting the braking capacity of a brake. Background technique [0002] In the current hoisting equipment (such as: tower crane), the brake of the hoisting mechanism has braking ability. When the braking ability of the brake reaches the set braking requirement, the hoisting mechanism will operate in a safe work in the state. [0003] However, with the increase of the working time of the hoisting equipment or the influence of other reasons (for example: the brake adjustment is not in place, or the brake pads are too worn), there is a decline in the braking capacity during the working process of the hoisting mechanism. The reduction of braking capacity in this way makes the brake unable to hold the brake, and then the "hook sliding phenomenon" in the engineering field occurs, which seriously affects the construction safety and red...
