Description

Technical Field

[0001] The invention relates to the technical field of working platforms, and in particular to an electric safety working platform with a stable mechanical structure. Background Art

[0002] In power construction, construction workers often encounter situations where they need to work at heights, but usually the construction sites and safety measures are leaky. For example, the existing steel box girders are only connected by high-strength bolts through the gusset plates. When workers work under such conditions, they only wear conventional high-altitude work safety ropes, which cannot guarantee the safety of construction workers. Falling deaths often occur, and it is inconvenient to hang the safety rope. During the work process, workers need to move the safety rope when transferring work positions, and the walking efficiency is very low. Therefore, the maintenance lifting platforms commonly used in power inspections are mostly scissor lifts. At present, the operation and maintenance methods of power communication equipment are not only using paper maintenance work orders for any In addition to the traditional operation and maintenance methods of dispatching services and checking equipment detailed information on paper materials, with the rapid development of RFID tag identification technology, the operation and maintenance of power communication equipment has begun to use RFID identification tag technology, which solves the problems of low work efficiency, large workload and easy errors caused by the traditional operation and maintenance method that requires manual viewing of paper materials to view the information of the maintenance equipment and manual recording of the on-site information of the maintenance equipment. However, before going to the on-site maintenance, the on-site operation and maintenance personnel need to download all maintenance tasks from the operation and maintenance main station in advance via USB or WIFI. After the maintenance is completed, the maintenance results also need to be imported into the operation and maintenance main station via USB or WIFI.

[0003] During the safety inspection and maintenance of power facilities by staff, the existing lifting platforms mainly require the maintenance staff to find a way to climb up by themselves, and the inspection platform usually has no fence, so the safety and convenience are poor. At the same time, during the use of the device, in order to facilitate the use of the device, it is usually necessary to adjust the orientation and height of the device, which makes the device prone to shaking when the orientation and height are adjusted, reducing the stability of the device when in use. Summary of the invention

[0004] 1. Technical issues to be solved

[0005] In view of the deficiencies in the prior art, the present invention provides an electric power safety work platform with a stable mechanical structure. The telescopic climbing ladder is pulled downward so that the telescopic climbing ladder can extend from the interior of the electric power installation work platform through the limit sliding hole and fit into the fixed balance support base. The limit blocking block can block the limit sliding hole to fix the telescopic climbing ladder. The staff can use the telescopic climbing ladder to climb up onto the electric power installation work platform to carry out electric power maintenance. After the staff climbs onto the surface of the electric power installation work platform, the sliding of the telescopic climbing ladder is utilized so that the staff can hold the handle and pull the telescopic climbing ladder upward. Through the continuous upward movement of the telescopic climbing ladder, the rubber filling pad can extend into the interior of the limit sliding hole to fix the telescopic climbing ladder, so that the telescopic climbing ladder and the protective metal rod structure can provide all-round protection for the staff on the electric power installation work platform, thereby improving the safety of the device when in use. The lifting fixed seat can drive the support rod to rotate. Since the support rod is connected to the sliding groove on the upper surface of the fixed balancing support base, the support rod can drive the limiting ball to slide inside the sliding groove when rotating, so that the position of the power installation work platform can be limited when adjusting the orientation, so that the power installation work platform is not easy to shake. When the power installation work platform is moving, the power installation work platform can drive the second support installation frame plate to move. When the second support installation frame plate moves upward, the support balance cross plate can be used to cross and vertically support the second support installation frame plate by utilizing the movement of the support balance cross plate. At the same time, the telescopic rod can be further extended and retracted under the influence of the movement of the second support installation frame plate, so that it can provide doubly support for the power installation work platform, making the height of the power installation work platform more stable when adjusted, etc., solving the problems of low safety and poor stability during orientation and height adjustment.
