Description

Spring reel with cable travel monitoring function Technical Field The utility model relates to the technical field of spring reels, in particular to a spring reel with a power stroke monitoring function. Background The spring winding drum is applied to the field of power supply of engineering vehicles. The spring reel is usually arranged at a high position near the vehicle and is approximately above the engineering vehicle and is responsible for the winding and unwinding functions of the power supply cable of the engineering vehicle. The similar products of the spring winding drum generally have no functions of detecting, forecasting and alarming the length of the cable, a driver of the engineering vehicle needs to control the vehicle and observe the situation that the cable of the spring winding drum is pulled when the engineering vehicle advances and retreats, so that the attention of the driver is intangibly increased, the engineering vehicle cannot be controlled in a carefree way, and if the driver is slightly careless or careless, the cable of the spring winding drum is possibly pulled by the vehicle, so that the engineering vehicle is out of charge, stopped and even a safety accident is caused. Therefore, there is a need to provide a spring reel with cable travel monitoring to solve the above-mentioned problems. Disclosure of utility model The utility model aims to provide a spring winding drum with a cable travel monitoring function, which solves the problem that the existing spring winding drum does not have the functions of cable length detection, prediction and alarm. The utility model provides a spring winding drum with a cable stroke monitoring function, which comprises a base, a driving device, a spring winding drum, a transformation ratio chain, a horizontal lead screw, a guide rail device, a wire arranging device, an electric cabinet and a mechanical multi-circle absolute value encoder, wherein the spring winding drum is rotatably arranged on the base through a rotating shaft, the driving device is connected with the rotating shaft of the spring winding drum, the guide rail device is arranged on one side of the spring winding drum, the wire arranging device is slidingly connected above the guide rail device, the horizontal lead screw is rotatably arranged below the guide rail device through the rotating shaft, the rotating shaft of the spring winding drum is in transmission connection with the rotating shaft of the horizontal lead screw through the transformation ratio chain, a cable part is wound on the spring winding drum and penetrates through the wire arranging device, the electric cabinet is arranged at one end of the spring winding drum, a controller and a signal forwarding device on the side of the spring winding drum, which is connected with the controller are arranged in the electric cabinet, the mechanical multi-circle absolute value encoder is arranged on the rotating shaft of the horizontal lead screw, the mechanical multi-circle absolute value encoder is connected with the controller in the electric cabinet, the signal forwarding device on the side of the engineering vehicle is connected with the signal forwarding device in the engineering vehicle, and the signal forwarding device on the vehicle communication system on the vehicle side is connected with the vehicle.
