As shown in Figure 3 and Figure 4, preferably, described inspection platform body also is provided with jacking system.Described jacking system is made of at least one variable-frequency motor 9, at least one interlock round bar 11, at least one first rope sheave 10, at least one second rope sheave 21 and two steel ropes 17 at least.9 of described variable-frequency motors are fixed on the connecting panel 6 of a side, and described variable-frequency electric arbor one end passes connecting panel 6 and is connected with the first rope sheave 10, and the other end connects into rigidity with an end of interlock round bar 11.Described interlock round bar 11 other ends pass side connecting plate 6, and are connected with the second rope sheave 21.Described two steel rope 17 upper ends are respectively around at the first rope sheave 10 and the second rope sheave 21 upper-level thresholds and fixing, and circular hole that the fag end axle 18 of platform 1 both sides is provided with and fixing is passed respectively in the lower end.Not during the use and maintenance platform, variable-frequency motor 9 backward rotation, the first rope sheave 10 and the second rope sheave 21 are packed up steel rope 17 simultaneously, and pulling platform 1 upward movement makes that inspection platform is folding to be packed up; During usage platform, variable-frequency motor 9 forward rotation, folding suspension rod opens under the Action of Gravity Field of platform 1, and variable-frequency motor 9 is controlled the descending speed of platform 1 by control steel rope 17.Preferably, described variable-frequency motor is also with auto-lock function, can automatically not descend after platform is packed up.
Such as Fig. 4 and Fig. 8, shown in Figure 9, preferably, the front side of described flexible inspection platform body or rear side (installation side of disconnected plate 6, guide rail 7) also are provided with movable railing 22.Described movable railing 22 is made of at least two anchor shaft 22-1, at least one the first movable railing 22-2, at least one the second movable railing 22-4, at least one threaded line pipe 22-3 and two bearing pin 22-5 at least.The anchor shaft 22-1 of described the first movable railing 22-2 one end and cross bar 4 one ends are hinged by bearing pin 22-5.The other end of described the first movable railing 22-2 also is provided with boss.One end anchor shaft 22-1 of described the second movable railing 22-4 one end and offside cross bar 4 are hinged by bearing pin 22-5.And the other end of described the second movable railing 22-4 has been attacked outside thread and has been served as with threaded line pipe 22-3 and be threaded.Described threaded line pipe 22-3 is pre-large post-small tubular, and large open end is attacked the negative thread that cooperates with the second movable railing 22-4 outside thread in the cylinder; After the boss socket of the small end of described threaded line pipe 22-3 and the first movable railing 22-2, connect into rigidity with the second movable railing 22-4 by helicitic texture.When platform 1 drops to assigned address, by turning on threaded line pipe 22-3, the first movable railing 22-2 and the second movable railing 22-4 are disconnected, remove its safeguard function, this moment, the operating personnel can climb up platform 1 smoothly.Before the operation, the first movable railing 22-2 is reconnected into rigidity with the second movable railing 22-4, recover its safeguard function.When leaving platform 1, operating process is the contrary operation process of climbing up platform.
The operating process of Foldable overhaul platform of the present invention is:
When using this Foldable overhaul platform, after the operating personnel enters sedan-chair top, and cage top overhauling is gone upward to the assigned address on hoistway top.The operating personnel is installed in the control button of the platform lifting device of sedan-chair top electric box by startup, make variable-frequency motor 9 forwards that are installed on the inspection platform and put down platform.After the Awaiting Overhaul platform was finished and opened, the operating personnel removed the threaded line pipe 22-3 on the movable railing 22, and movable rail is disconnected; The operating personnel climbs up inspection platform 1.
Before the operation, the operating personnel needs first movable rail 22 to be recovered safeguard function, and then elevator can normally move.
During operation, if the operating personnel need traveling overhaul platform to opposite side (as originally at host computer side, need move to control housing, velocity limiter then) operation, the operating personnel can be by being installed in the unlock button of the electromagnetic locking device on the inspection platform, make band bearing roller 8 recover to roll, can move to target side this moment with platform.After roller moved to target side, electromagnetic locking device can automatically recover lock-out state, and locking strip bearing roller again.
After the operation, before the operating personnel leaves inspection platform, first overhauling elevator to be up to the position of hoistway top appointment, dismantle again movable railing 22; After leaving inspection platform and entering into sedan-chair top, the operating personnel locks movable railing 22 again, and packs up inspection platform by the push button control jacking system of sedan-chair top electric box.
The above is preferred embodiment of the present invention only, and protection scope of the present invention is not limited to this, anyly all belongs within the protection domain of the present invention based on the equivalent transformation on the technical solution of the present invention.
