Four corners between bottom plate and top plate pass through longitudinal oil cylinder connection, the both ends of cross link be inserted into respectively top plate and
In rod slide slot on bottom plate, the pulley 24 of connecting rod two end is located in corresponding pulley embedding slot.
The center position of bottom plate and top plate is equipped with longitudinal oil cylinder.
Lifting device is installed on the top surface of traveling control vehicle 1, and lifting device assembles on same vertical plane in the present embodiment
Two groups, lifting device by bottom plate each other with top plate is detachable is fixedly connected.When operating environment needs further rising height
When, multiple groups lifting device can be assembled.
As shown in figure 3, operation post 3 includes operation plate 31 and slip ring 32, if the lateral margin of operation plate surrounding is disposed with
Dry rectangular recess in the horizontal direction, the height of rectangular recess are less than the outer diameter of slip ring, and the top surface of operation plate corresponds to rectangle
Slip ring mounting groove is provided at groove location, slip ring 32 is plugged in mounting groove.
Operation post is installed on the top surface of lifting device, installs decelerating motor 4 at the end face center position of operation plate 31, subtracts
The output shaft of speed motor is upward.
As shown in figure 4, the bottom stage of vertical supporting bar 5 is connected with adjustable plate 51 in parallel, adjustable plate is uniformly distributed along its length
There is row's circular hole.
In conjunction with shown in Fig. 1, Fig. 5 and Fig. 6, the lower end of vertical supporting bar 5 and the output axis connection of decelerating motor.Longitudinal bracing
The top of bar is fixedly connected with transverse support bar 6, and the end of transverse support bar is equipped with lateral oil cylinder 7, the piston of lateral oil cylinder
Bar is located on the extended line of transverse support bar 6, and the outer end face of piston rod is connected with protection fixed pulley, the upside of piston rod outer end section
Protection fixed pulley and fixed pulley are separately installed with downside.
The downside of 6 outer end of transverse support bar section is axially fixed the fixed pulley conllinear with fixed pulley on piston rod.
The both ends of life bar 9 are symmetrically provided with two groups of through-holes, and the both ends section of life bar 9 is symmetrically fixed with stop collar 91, two limits
Life bar upper sleeve through between the ring of position has sliding retaining ring 92.Two groups of through-holes at life bar both ends are coated with two lifting steel wires respectively
Rope 93.
The both ends of connecting steel wire ropes 62 are respectively connected with hook, and the circular hole for being hung on adjustable plate 51 of one end connects steel wire
Rope successively winds fixed pulley, and the hook of the other end catches on the lifting wirerope of life bar.
One end is fixedly connected with life bar both ends after the protection winding protection fixed pulley 71 of wirerope 72, and the other end passes through piston rod
Clump weight 8 is connected after the through-hole in middle position.
Safety rope 911 is equipped in the sliding retaining ring 92 of life bar 9, the both ends of safety rope are respectively connected with hook, and one end connects
Safety hook 912 is connect, safety hook is lock on the slip ring 32 of operation post 3, and the other end of safety rope connects safety buckle 913,
The safety belt of high altitude operation personnel is buckled on sliding retaining ring, while safety buckle locks high altitude operation personnel.
Configuration hydraulic station gives each oil cylinder fuel feeding on traveling control vehicle 1, and the piston rod of each oil cylinder is made to execute expanding-contracting action.
The working principle of the present embodiment falling proof device is as follows:
First high altitude operation personnel by the back belt type safety belt hanging buckle of wearing on sliding retaining ring 92, while by safety rope one
The safety hook 912 at end carries out hanging buckle, the safety rope other end according to the embedded slip ring 32 that high altitude operation environmental selection is suitble to
Safety buckle 913 lock high altitude operation personnel safety belt.
The operator of traveling control vehicle 1 controls longitudinal hydraulic pump 24 by hydraulic station 11 and works, and lifting device 2 rises top
Operation post 3 is risen, and then drives life bar 9 and hanging buckle to rise to suitable high-altitude in the high altitude operation personnel on sliding retaining ring 92 and makees
Industry position.
The both ends of connecting steel wire ropes 62 are separately connected adjustable plate 51 and life bar 9, when solving high altitude operation person works
Existing falling risk, protection 72 both ends of wirerope are fixedly connected with clump weight 8 and life bar respectively.When connecting steel wire ropes 62 are anticipated
When outer fracture, life bar 9 falls, drive protection wirerope 82 tighten because protection wirerope length much smaller than life bar with
Height between ground is fallen so that life bar is vacantly unlikely, is further improved so that clump weight is blocked by piston rod
Safety.
After the safety belt of high altitude operation personnel itself is surprisingly broken, safety rope 911 is in embedded slip ring 32, sliding button
It is tightened between the high altitude operation personnel that ring 92 and safety buckle 913 connect, so that it is unlikely below workbench to be suspended on operating personnel
It falls, plays the role of auxiliary safety belt.
By the different circular holes on adjustable plate 51, operating personnel can realize height on operation post 3 and finely tune, and improve
The practicability of device.
Decelerating motor 4 and vertical supporting bar 5 are rotatablely connected, and vertical supporting bar drives transverse support bar 6, transverse hydraulic cylinder 7
It is rotated within the scope of 360 ° with piston rod around decelerating motor, transverse hydraulic cylinder controls the diameter of the adjustable work of stretching of piston rod
To coverage area, the practicability of further lifting device.
The utility model is locked by wirerope, protection wirerope and safety rope, avoids high altitude operation personnel
Because the fall event occurred when wire cable rupture, protection wire cable rupture or safe fracture of rope, triple safeguard procedures mention significantly
The high safety of device, ensure that the safety of high altitude operation personnel.
