Description

Anti-falling device for feeder trolley Technical Field The utility model relates to the technical field of feeding processing, in particular to a feeder trolley anti-falling device. Background The feeder is adopted in workshop processing to carry out feeding operation, and the existing feeder is a pushing structure formed by a feeding trolley and a hydraulic cylinder, and the hydraulic cylinder is utilized to drive the trolley to reciprocate, so that the feeding operation is completed by pushing materials into the rotary kiln. Because the flexible end of pneumatic cylinder is connected with the round pin axle that adopts between the feed dolly, in the use, the round pin axle is the risk that exists probably taking place to drop, this just can lead to the feed dolly to slide into in the rotary kiln along the pay-off passageway, not only causes feeding equipment to damage, also influences the processing condition of follow-up material, and for this reason, design a device that effectively prevents the feed dolly from taking place the condition of falling. Disclosure of utility model According to the technical problems, the utility model provides the anti-falling device for the feeder trolley, the problem of whether the feeding trolley is loose in connection or not is monitored through the position sensor additionally arranged at the joint of the hydraulic cylinder and the feeding trolley, and the feeding trolley is pulled when the steel wire rope is positioned and loosened through the designed tensioning assembly, so that the feeding trolley is prevented from falling into the rotary kiln. In order to achieve the above purpose, the technical scheme of the utility model is as follows: The feeder trolley anti-falling device is characterized by comprising a pulley, a steel wire rope, a position sensor and a tensioning assembly, wherein the tensioning assembly is arranged on a bottom plate, the steel wire rope is arranged in the tensioning assembly, one end of the steel wire rope extends out of the tensioning assembly and is sequentially connected with the pulley and a feeding trolley, the steel wire rope is fixedly connected with the feeding trolley, the feeding trolley is arranged in a feeding channel, the rear side of the feeding trolley is connected with the telescopic end of a hydraulic cylinder, the position sensor is arranged at the joint of the feeding trolley and the telescopic end of the hydraulic cylinder, The tensioning assembly comprises a winding box, a winding roll, a coil spring and a limiting compression part, wherein the winding roll is arranged on a central column arranged in the winding box, the winding roll is provided with the coil spring, one end of the coil spring is connected in a clamping groove arranged on the central column, the other end of the coil spring is connected in the clamping groove arranged on the winding roll, the limiting compression part is arranged at the outlet of the winding box, The limit pressing part is composed of an electric push rod and a limit pressing plate, the electric push rod is fixedly arranged at the outlet of the coiling box through a mounting plate, the telescopic end of the electric push rod stretches into the outlet of the coiling box and is connected with the limit pressing plate, Preferably, the inner side surface of the limiting pressing plate is provided with a plurality of tooth blocks, so that the limiting pressing plate is more stable when limiting and pressing the steel wire rope. Further, a feeding port is arranged above the feeding channel and used for feeding materials into the feeding channel. Further, the hydraulic cylinder is installed on the support frame, and the pulley is installed on the support frame. Further, electric putter and position sensor all are connected with outside controller electricity, monitor through position sensor and whether take place not hard up between feed dolly and the flexible end department of pneumatic cylinder, signal transmission to controller, control electric putter start up and realize spacing clamp plate compress tightly wire rope and accomplish the spacing to wire rope.
