Description

Movable railway platform protection device Technical Field The utility model relates to the technical field of platform protection devices, in particular to a movable railway platform protection device. Background In modern railway transportation, a railway platform safety device is an important facility for ensuring the safety of passengers and maintaining the order of a platform, and aims to prevent accidents and improve the safety of the platform, wherein fixed guardrails are adopted to realize the functions of isolation and protection. In the use process of the platform protector, the traditional platform protector mostly adopts the fixed guardrail, the design of the traditional guardrail is often heavy, not only occupies larger space, but also is unfavorable for the overall beauty and space utilization of the platform, and when the platform needs to be extended or stored, the operation process is complex and time-consuming. Therefore, to the inconvenient problem of realizing convenient extension and accomodating to the guardrail, can design a portable railway platform protector, when platform protector is in the in-process of using, the balancing weight drives the loading board and falls when the upper end of limiting plate, and then can reach the purpose of convenient extension guardrail, simultaneously, through ingenious gear drive and spring return mechanism, realized convenient extension and accomodating of guardrail, effectively improved railway platform's security and convenience. Disclosure of utility model In order to overcome the platform protector in the in-process of using, traditional fixed guardrail is when needs extend or accomodate, and operation process is complicated and consuming time, and this greatly reduced platform's availability factor, especially in the peak period, the extension of guardrail and the speed of accomodating directly influence passenger's traffic flow degree of getting on or off, need improve, and then inconvenient to realize convenient extension and the problem of accomodating to the guardrail. The technical scheme includes that the movable railway platform protecting device comprises a movable guardrail, a cavity, a rolling shaft, a protective net, a movable column, an inner cavity, a driving shaft, rotating gears, lifting toothed plates, driving gears, driven gears, transmission toothed chains, driven shafts, rotating wheels, reset springs, limiting plates, bearing plates and balancing weights, wherein the cavity is formed in the side wall of the right end of the movable guardrail, the rolling shaft is rotatably arranged in the cavity, the movable column is arranged on the right side of the movable guardrail, the protective net is wound on the side wall of the rolling shaft, the inner cavity is formed in the movable column, the driving shaft is rotatably arranged in the inner cavity, the driving gears are fixedly arranged on the side wall of the driving shaft, the driven shafts are rotatably arranged on the bottom wall of the movable column, driven gears are fixedly arranged on the side wall of the driven shaft, the transmission toothed chains are fixedly arranged in the inner cavity, two groups of the rotating wheels are fixedly arranged at two ends of the driven shafts, the lifting toothed plates are fixedly arranged in the inner cavity, the rotating gears are fixedly arranged on the side wall of the driving shaft, the bearing plates are fixedly arranged at the upper ends of the guide toothed plates, the balancing weights are fixedly arranged above the bearing plates, a plurality of groups of reset springs are arranged in the inner cavity, and the limiting plates are fixedly arranged in the inner cavity. Preferably, when the platform protector is in the in-process of using, at first, make the balancing weight realize the unblock state when extending the guardrail, at this moment, the bottom of balancing weight and the top of loading board are contradicted and are extruded, and, under the action of gravity of balancing weight, can drive loading board and lift pinion rack and descend the motion, in this process, multiunit reset spring receives tensile then takes place deformation, for follow-up reset motion holds the power, when lift pinion rack carries out continuously and descends, because lift pinion rack and rotation gear engagement, lift pinion rack then can drive rotation gear and driving shaft realization rotation, the driving gear then can drive the rotation of transmission pinion rack, the transmission pinion rack then can drive the driven shaft realization rotation through the driven gear, then can drive both ends rotation wheel realization, thereby can drive the spliced pole and carry out steady removal to the right side, in this process, the spliced pole then can pull protection network one end realization effect, when the balancing weight drives the loading board and falls to the upper end of limiting plate, owing to lift pinion rack and rotation ge
