Description

Car top sliding guardrail for elevator Technical Field The utility model relates to the technical field of elevators, in particular to a car top sliding guardrail for an elevator. Background Conventionally, a car roof guardrail for protecting the safety of maintenance personnel is installed on the car roof of an elevator. The car roof guardrail is generally designed into a three-side guardrail structure, and the guardrail is not arranged on one side of the hoistway wall with a door opening, so that maintenance personnel can conveniently enter and exit the car roof. However, when the distance between the outer edge of the car roof and the hoistway wall on the landing door side exceeds 0.30 meters, it is often necessary to install a protective net within the hoistway that covers the entire hoistway to prevent maintenance personnel from accidentally falling. But this protection network not only installs loaded down with trivial details, wastes time and energy, and increases maintenance cost. Disclosure of utility model Aiming at the technical problems, the utility model aims to provide the car top sliding guardrail for the elevator, which can realize four-side protection on the car top of the elevator so as to effectively protect maintenance personnel, is convenient to get in and out of the car top, has simple structural design, is convenient to install, effectively meets the actual use requirement of the elevator, and has strong practicability. The technical scheme of the utility model is realized by that the car top sliding guardrail for the elevator comprises three-side guardrails and an in-out guardrail; the three-sided guardrail is provided with an open end extending along the transverse direction; The inlet and outlet guard rail is arranged in the open end of the three-surface guard rail and comprises a chute, a sliding rod, a limit switch and a locking assembly; the two groups of sliding grooves are oppositely arranged at intervals in the transverse direction and extend along the up-down direction, and an inlet and outlet passage is formed between the two groups of sliding grooves; The sliding rods of the groups are connected with the sliding grooves on the two sides in an up-down sliding way, and have blocking positions for preventing the passage of the passage and access positions for allowing the passage of the passage; The locking component is arranged corresponding to each group of sliding rods and is used for locking or unlocking the sliding rods at the interception position; The limit switch is arranged corresponding to at least one group of slide bars, the slide bars are in contact with the limit switch in the interception position, and the slide bars are far away from the limit switch in the in-out position. Furthermore, the in-out guardrails comprise cross beams, and a plurality of groups of cross beams are arranged between each group of sliding grooves and the three-surface guardrails in parallel up and down. Furthermore, the first end of the cross beam is welded and fixed with the sliding groove, the second end of the cross beam is welded with a connecting plate, and the connecting plate is fastened and connected with the three-surface guardrails through a bolt assembly.
