Summary of the invention
The purpose of this utility model is to provide a kind of valve tower maintenance special operation platform device, and it can improve the efficient of service work personnel operation on the valve tower application of crossing, and then improves the availability factor of direct current, and reduces the risk of valve tower height idle job.
The technical solution of the utility model is: valve tower maintenance special operation platform device is comprised of guide rail and job platform; Guide rail is comprised of two symmetrically arranged supervisors, cushion block and aluminum corner brace, and supervisor is fixed on cushion block, and cushion block is connected with aluminum corner brace; Job platform is comprised of main wheel assembly, panel and support, wheel assembly, the main wheel assembly is arranged at the two ends of panel and support, be connected with support by the wheel carrier in the main wheel assembly, be connected with the wheel assembly on the panel bottom bracket, on the main wheel assembly, brake gear is housed.
The main wheel assembly is configured to by wheel, wheel shaft and bearing arrangement, brake gear and wheel, wheel is contained on wheel shaft by bearing arrangement, wheel shaft is fixed on wheel carrier, brake gear is fixed on wheel carrier, brake gear connects the butterfly screw rod by brake shoes and consists of, and guide post is arranged at the top of brake gear on wheel carrier.
The wheel assembly is comprised of wheel carrier and wheel, and wheel carrier is fixed on an end of support, and wheel is fixed on wheel carrier.
The bolt that is used for fixing cushion block of the supervisor termination of guide rail protrudes upward bolt head, as the spacer pin of wheel.
The job platform of the present utility model brake gear that roller arranges that horizontally slips, the assurance personnel do not horizontally slip during operation on job platform; Be provided with spacer pin on guide rail, in case job platform pushes through the position.Application by it improves the efficient of service work personnel operation on the valve tower, and then improves the availability factor of direct current, and reduces the risk of valve tower height idle job.Job platform and guide rail are used in conjunction with, and not only can save strength but also avoid personnel to place job platform collision equipment.Be issued to safe, reliable, easy to carry, easy to use effect in the prerequisite that satisfies requirements.
