Description

Technical Field

[0001] This utility model belongs to the field of car wash machine technology, and specifically relates to a monitoring device for the lifting belt of the roller brush on a car wash machine. Background Technology

[0002] Car wash machines use roller brushes to clean the surface of vehicles through mechanical friction and washing, requiring them to move up and down repeatedly during the cleaning process. Currently, when belt lifts are used to raise the roller brushes, there are issues that cannot be effectively monitored if the lift malfunctions, such as belt jamming, obstruction of the roller brush's movement, or a rapid descent of the brush. This poses certain safety hazards to both the equipment and the vehicles being washed. Utility Model Content

[0003] The purpose of this utility model is to provide a monitoring device for the lifting belt of the roller brush on a car wash machine.

[0004] This utility model is achieved through the following measures: a monitoring device for the lifting belt of the upper roller brush of a car wash machine, including a gantry frame, an upper roller brush that moves up and down along the gantry frame, and a belt lifting machine that drives the upper roller brush to move up and down. The belt lifting machine is characterized in that two belt lifting machines are provided and symmetrically arranged on both sides above the gantry frame, and a monitoring component is provided on the gantry frame and on the outside of the upper belt. The monitoring component includes a retractor with a tape wound around it, a guide pulley between the retractor and the belt, and the end of the tape passing over the guide pulley and being fixedly connected to the movable end of the belt. It also includes sensors for monitoring the extension length and speed of the belt conveyor, which transmit monitoring signals to the controller of the car wash machine. The controller receives the sensor signals, compares them with thresholds, and controls the start and stop of the belt lift.

[0005] The sensor is an encoder, and the encoder shaft is fixedly connected to the retractor's roller or drive shaft.

[0006] The sensor is a photoelectric sensor, which is fixed below the tape and located between the guide roller and the take-up unit. The side of the tape facing the photoelectric sensor has a mark that matches the photoelectric sensor.

[0007] The markings are generally reflective or fluorescent.

[0008] It also includes a locking component for the tape.

[0009] The locking assembly includes a telescopic rod, the housing of which is connected to the gantry frame, and the push rod of the telescopic rod is equipped with a pressure roller, which is located above the guide wheel and can squeeze the tape onto the guide wheel; The controller receives the signal from the sensor and compares it with a threshold value to control the telescopic rod to start and compress the tape. The telescopic rod can be an electric actuator or a hydraulic rod.

[0010] The retractor can also be a retractor with a locking structure, such as a seat belt retractor, which is existing technology and will not be described in detail here.

[0011] Two monitoring components are symmetrically arranged.

[0012] Working principle: The end of the belt roll is fixedly connected to the movable end of the belt, allowing it to move up and down synchronously with the belt. The belt roll is pulled out and retracted simultaneously with the roller brush belt. The sensor transmits the belt extension and retraction length and speed to the controller in real time via voltage signals. The controller controls the start and stop of the belt lift and the telescopic rod through preset thresholds or programs.

[0013] The beneficial effects of the technical solution provided by this utility model embodiment are: the status of the roller brush lifting belt on the car wash machine can be monitored in real time to ensure the normal operation of the lifting machine; a locking component is also provided to lock and protect the upper roller brush when its movement speed decreases.
