Description
Technical field
The present invention relates to the safety protection equipment fields of elevating mechanism.
Background technique
Currently, elevating mechanism in the prior art has very much, such as cylinder, hydraulic cylinder, electric pushrod, crank connecting link, intersection
Arm etc. usually only relies on resistance of the elevating mechanism from stopping when and comes to mesh after object is given rise to designated position
The height of mark object is locked, and can not be locked to elevating mechanism there is no special safety prevention measure, so that mesh
Mark object may be damaged because falling suddenly, stability and along with a degree of security risk, and then to elevating mechanism and
Safety brings strong influence.
Specifically, as shown in fig. 7, by taking transposition arm 1 as an example, usually it is arranged one between interior scissor arms and outer scissor arms
Hydraulic cylinder 11, flexible by hydraulic cylinder 11 lift or transfer object to control transposition arm 1, once at this point, hydraulic station or liquid
Pressure pipe road is broken down, and object will directly drop, and causes tremendous influence, in this regard, it is anti-how to carry out safety to elevating mechanism
Pendant becomes those skilled in the art's technical problem urgently to be resolved.

Specific embodiment
As shown in figs. 1-7, the elevating mechanism (as transposition arm 1) has driving assembly (as hydraulic cylinder to the present invention
11), the safety lock 25 includes pedestal 251, the body of rod 252, lockable mechanism and tripping-gear, the bottom end of the pedestal 251 and drive
The bottom end of dynamic component is connected, and the top of the body of rod 252 is connected with the top of driving assembly, i.e., is locked in safety hydraulic
The side of cylinder, and the both ends of safety lock and the both ends of hydraulic cylinder are connected on identical position with identical connection type, institute
It is parallel with pedestal 251 and be threaded through the top of pedestal 251 to state the body of rod 252;
The top of the pedestal 251 is also fixedly connected with the container 250 of the body of rod 252 described in empty set, 252 two sidewalls of the body of rod
On be evenly equipped with several latches 2520;
The lockable mechanism includes tension spring 2531 and a pair of of lock pin 2532, a pair of of lock pin 2532 be divided into the two sides of the body of rod 252 and
In container 250, the root of a pair of of lock pin 2532 is articulated in container 250 and end is against the two of the body of rod 252 respectively
In gap between the adjacent latch 2520 of side, the back of the container 250 offers a pair of of rear arc through-hole, the lock pin
Be fixedly connected with spring stack 2533 on 2532 side end face, the spring stack 2533 be slidably connected in rear arc through-hole and
It extend out to outside container 250, the both ends of the tension spring 2531 are respectively fixedly connected with two spring stacks 2533;So that without external force shadow
When ringing, a pair of of lock pin is held by tension spring always, and withstands the body of rod with latch cooperation, is maintained at lockup state, is prevented body of rod downlink
It bounces back into pedestal;
The front of the container 250 offers a pair of of front arc through-hole, and the lock pin 2532 is backwards to the end face of spring stack 2533
On be fixedly connected with guide post 2534, the guide post 2534 is slidably connected in front arc through-hole and extend out to container 250
Outside;
The tripping-gear includes handle 2541, connecting rod 2542, jacking block 2543, sliding rail 2544 and a pair of of guide wheel 2545, the hand
The middle part of handle 2541 is hinged on the bottom end of pedestal 251, the top of the hinged handle 2541 in the bottom end of the connecting rod 2542, described
Sliding rail 2544 is fixedly connected on outside container 250 and between two guide posts 2534, and the jacking block 2543 is in up-small and down-big
Trapezoidal, the jacking block 2543 is slidably connected on sliding rail 2544 and hinged with the top of connecting rod 2542, a pair of guide wheel 2545
It is respectively hinged on the end that a pair of of guide post 2534 is extend out to outside container 250 and a pair of of guide wheel 2545 fits in top respectively
The two sides of block 2543.In this way, when operator's rotational handle makes jacking block uplink, it can be under the influence of jacking block trapezium structure
The spacing of a pair of of guide wheel is set constantly to become larger, so that a pair of of lock pin overcomes tension spring active force to strut outward, with the card on the body of rod
Tooth separation, allows the body of rod and pedestal relative motion, is in releasing orientation.Hereafter, handle is inverted, so that jacking block downlink, that is, may make
A pair of of lock pin is tightened under the action of tension spring and withstands the body of rod with latch cooperation, and lockup state is maintained at.
In this way, safety lock can be realized between lockup state and releasing orientation by the simple operations of operator in this case
Be switched fast, when safety lock is in releasing orientation, lifting assembly can be freely lifted, thus it is convenient, efficiently make height
Adjustment;And when safety lock is in lockup state, the body of rod will be unable to downlink, finish to effectively prevent device height adjusting
Occur the problem of unexpected downlink afterwards, the stable operation of mechanism be effectively ensured, has improved safety of the lifting assembly after rise,
Play the role of security protection.
In addition, the safety lock in the present invention can be also directly installed in conventional elevator structure, it can be independent to also have
Installation, is easy to the advantages that marketing at wide adaptation range.
The sliding rail 2544 is parallel to the body of rod 252 and is arranged, and the hinge joint of the handle 2541 and pedestal 251, which is in, to be slided
In plane where 2544 center line of rail, also it is fixedly connected on the pedestal 251 close to switch 2510, it is described close to switch
2510 in the plane where 2544 center line of sliding rail.Both in this way, connecting rod, handle are turned on straight line, i.e.,
When being in the plane where center line of guide rail, make its turn to work as operator's rotational handle for the dead point of handle rotation
When moving to dead point, a pair of of lock pin may make to be maintained at releasing orientation, so that operation difficulty be greatly reduced, ensure that equipment operation
Stability.At the same time, signal can also be passed to control centre close to switch, so that lifting assembly is allowed to go up and down, thus
It ensure that the safety of equipment operation.
The lock pin 2532 is hinged by shaft with container 250, the circle where the center line of the front arc through-hole
The axle center of the heart and shaft overlaps, and the axle center in the center of circle and shaft where the center line of the rear arc through-hole overlaps.Even if
The movement for obtaining lock pin, spring stack and guide post is more stable, smooth.
