Specific embodiment
Below in conjunction with attached drawing and technical solution, a specific embodiment of the invention is further illustrated.
A kind of a kind of snap-gauge turnover mechanism that the overturning for snap-gauge proposes, specific implementation method are as follows：
The snap-gauge turnover mechanism is made of five parts：First is that spring equalizing device, operator when for saving overturning
Power；Second is that guiding device 9, for guide steel wire rope 7 motion profile and prevent falling off for wirerope 7；Third is that bidirectional slide wheel
Group 10, for determining the specific motion profile in 7 use process of wirerope；Fourth is that snap-gauge lock 11, for determining that snap-gauge is overturn
Suspended position afterwards；Fifth is that bracket 12, for spring equalizing device to be mounted on main body frame.The specific structure is shown in FIG. 3.
Spring equalizing device by shell 1, mounting base 2, wind spring 3, cone pulley 4, adjust worm screw 5, latch 6, wirerope 7, hang
Hook 8 forms；Its principle is to reach operation object without weight or lower weight state.Specific structure is such as
Shown in Fig. 1 and Fig. 2.
The application method of snap-gauge turnover mechanism：
(a), bracket 12 is installed on main body frame, and the mounting base 2 of spring equalizing device is mounted on bracket 12, is passed through
Suspension hook 8 is connect with snap-gauge, will be in spring equalizing device according to the installation site of the overturning route determination bidirectional slide wheel group 10 of snap-gauge
Wirerope 7 be installed in bidirectional slide wheel group 10, after wirerope 7 installs, guiding device 9 is installed in mounting base 2, is passed through
Trace simulation is overturn, determines the position after snap-gauge is hung up, for installing snap-gauge lock 11.
(b), the adjusting worm screw 5 on adjustment spring balancing device, makes the equilibrant force of spring equalizing device reach zone of reasonableness.
When clockwise adjust, counterpoise increases, otherwise counterpoise is then reduced.With the elongation and shortening of wind spring 3, pulling force
Constantly changing, spring equalizing device is balanced using this principle to by the own wt of operation object, makes to be operated
Object reaches without weight or lower weight state.
(c), it when unloading operates object from spring equalizing device, needs first to pull out 6 pull rod of latch, rotates clockwise 30 °,
It puts back in card slot, after cone pulley 4 is lockked, then removal operation object, it is quickly withdrawn to prevent Condition of Sudden Unloading suspension hook 8 and hurts sb.'s feelings and damage work
Tool.Particular condition in use is as shown in Figure 4.
Points for attention in use process are as follows：
(a), it when dismantling spring equalizing device, needs first to adjust worm screw 5 and rotates counterclockwise, wind spring 3 is made to be completely in pine
Other work can be carried out when relaxation state.
(b), safety inspection periodically should be carried out to spring equalizing device.
(c), when spring equalizing device is laid up for a long time, off-load to save, guarded against damp, in case wind spring 3 gets rusty.
Working efficiency calculates：
Known snap-gauge length 1500mm, weight G are 10.5Kg, i.e. 105N, and the maximum pull of spring equalizing device adjusts model
15-22Kg is enclosed, choosing maximum pull in use is 20Kg, i.e. 200N；The length of pulling force and the wirerope of stretching 7 is at line
Property direct ratio, 7 maximal tensility 1500mm of wirerope.
1, before using snap-gauge turnover mechanism of the invention
When angle is 45 degree,
F1·L1=GL2
F1× 1565=105 × 720
F1=48.3N
When angle is 90 degree,
F2·L1=GL2
F2× 1565=105 × 815
F2=54.7N
2, after using snap-gauge turnover mechanism of the invention
When angle is 45 degree,
F1·L1+FBullet·LBullet=GL2
F’1=12.8N
When angle is 90 degree,
F2·L1+FBullet·LBullet=GL2
F’2==27.1N
Wherein：
F1Before using snap-gauge of the invention to overturn structure, the power of operator's application when angle is 45 °；
F2Before using snap-gauge of the invention to overturn structure, the power of operator's application when angle is 90 °；
