78 drive rods 1 being fixedly connected move.
When driving motor 73 damages, the driving motor 73 is in and state is freely rotated, at this moment using being fixed on carriage 8
On guide seat 5 drive rod 1 is acted on by guide wheel 11, drive connecting rod 78 and Mobile base 75 to move, at this time 77 tooth of gear
Row 76 is in passive movement state.
The driving motor 73 drives drive rod 1 to move horizontally, and is not only limited to the structure of 77 tooth row 76 of gear, also wraps
Include a variety of implementations.
As shown in Fig. 2, the guide seat 5 has upper oblique boot segment 51, vertical boot segment 52 and oblique boot segment 53, institute
It states vertical boot segment 52 to be fixed on the doorframe of 8 switch gate side of carriage, upper oblique 51 lower end of boot segment and vertical boot segment
52 are connected, and upper oblique 51 upper end of boot segment, which is tilted towards in the middle part of carriage 8, to be extended；53 upper end of oblique boot segment and vertical guidance
Section 52 is connected, and oblique 53 lower end of the boot segment inclination is towards extending in the middle part of carriage 8, the upper oblique boot segment 51, vertical boot segment
52 and oblique boot segment 53 with carriage 8 move up and down and respectively with guide wheel 11 rolling support.
If driving motor 73 is unable to drive drive rod 1 and moves horizontally, when lift car 8 moves across driving from top to bottom
When bar 1, oblique boot segment 53 can occur to roll with the guide wheel 11 on drive rod 1 first to be supported, under the drive of guide wheel 11,
Drive rod 1 can be moved towards 8 switch gate side of carriage；When guide wheel 11 rolls on vertical boot segment 52, the drive rod 1 is arrived
Up to most inboard position, 2 full retraction of protective layer is got up at this time；Upper tiltedly draw when guide wheel 11 is entered by vertical boot segment 52
When leading section 51, under the action of counter weight construction 6, the drive rod 1 slowly reaches outermost locations, and all protective layers 2 will at this time
Can be fully open, to achieve the effect that protection.When lift car 8 moves across drive rod 8 from the bottom up, upper oblique boot segment
51, which can occur rolling with the guide wheel 11 on drive rod 1 first, supports, and under the drive of guide wheel 11, drive rod 1 can be towards carriage 8
The movement of switch gate side；When guide wheel 11 rolls on vertical boot segment 52, the drive rod 1 reaches most inboard position, this
When 2 full retraction of protective layer is got up；When guide wheel 11 enters oblique boot segment 53 by vertical boot segment 52, in counterweight
Under the action of structure 6, the drive rod 1 slowly reaches outermost locations, and all protective layers 2 will be fully open at this time, thus
Achieve the effect that protection.
Preferably, the counter weight construction 6 includes drawstring 61, fixed pulley 62 and pouring weight 63；Described 61 one end of drawstring is connected to
The side of drive rod 1,61 other end of drawstring are connected with pouring weight 63 later around fixed pulley 62；1 two sides pair of drive rod
Ground setting two is claimed to assemble weight structure 6；In this way, resetting drive rod 1 by the gravity of pouring weight 63.
