Abstract
The utility model is related to a kind of centrifugal stoppers for balancer, including driven shaft, brake rotor, bearing block and brake arm, one end of the driven shaft is connected by sunk screw with brake rotor, bearing block is installed by screw on the outside of the brake rotor, one end that mounting hole on the bearing block passes through the pivotal mounting connection brake arm, the brake arm is the arcuate structure on the outside of brake rotor, the other end of the brake arm is connected by extension spring with brake rotor, it is equipped with boss in the outside that the brake arm is connected with bearing block, by the boss braking is contacted with brake ring inner bore of part.The utility model novel in structural design, by the way that centrifugal stopping assembly being arranged on driven shaft, under the influence of centrifugal force, by the leverage of the boss and brake ring endoporus of brake arm, realize the stopping of hoisting mechanism, it avoids the rapid increase of suspension hook from bringing injury to personnel, improves the security performance of balancer.
Description
Technical field
The utility model is related to a kind of stoppers, specifically a kind of centrifugal stopper for balancer, belong to
Hanging device technical field.
Background technology
Balancer is a kind of auxiliary tool of the hanging larger production operation equipment of weight.It continues for being engaged on production line
Property, repetitive operation personnel use, for hanging, concentrate, carry and remove tool.It is easily operated pneumatic, electrical and liquid
Pressure tool；Band safety device, can avoid suspension object fall and can manual locking suspended matter device.But it is operating
When balancer, when suspension hook is in lower position, at this time in the case where non-loaded or load is smaller with suspension hook at present under balancer
If pinning " rising " button for a long time not close, the lower suspension hook in lower end can constantly accelerate to move upwards（3~5m/s）, high speed
The lower suspension hook risen is possible to bring injury and damage to operating personnel and surrounding people and article.
Utility model content
Technical problem to be solved in the utility model is, the shortcomings that for the above prior art, proposes a kind of for putting down
The centrifugal stopper of weighing apparatus, by the improvement to its structure, when the lower suspension hook of balancer runs up speed in 3~5m/s
When range, lower suspension hook can stop moving upwards moment, quickly move the injury brought to personnel upwards to avoid gib head.
In order to solve the above technical problems, the utility model provides a kind of centrifugal stopper for balancer, including
One end of driven shaft, brake rotor, bearing block and brake arm, the driven shaft passes through sunk screw and brake rotor phase
Even, bearing block is installed by screw on the outside of the brake rotor, the mounting hole on the bearing block passes through pivotal mounting company
One end of the brake arm is connect, the brake arm is the arcuate structure on the outside of brake rotor, and the other end of the brake arm is logical
Overstretching spring is connected with brake rotor, boss is equipped in the outside that the brake arm is connected with bearing block, by described convex
Platform contacts braking with brake ring inner bore of part.
The technical solution that the utility model further limits is：It is previously described for the centrifugal stopper of balancer, in order to
Ensure that the rotation of pivot and brake arm is good, neck bush, the brake arm and axis are equipped between the pivot and bearing block
It holds and is equipped with washer between block.
Further, the centrifugal stopper of balancer, one end of the brake arm connection extension spring are previously described for
Equipped with multiple spring mounting and adjustings hole, by adjusting the installation site of extension spring, to change brake arm at various speeds
Skidding effect.
The utility model has the beneficial effects that：The utility model novel in structural design is centrifuged by being arranged on driven shaft
Formula stops assembly, under the influence of centrifugal force, by the leverage of the boss and brake ring endoporus of brake arm, realizes hoisting mechanism
Stopping, avoiding the rapid increase of suspension hook from bringing injury to personnel, improve the security performance of balancer.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model.
Fig. 2 is the side schematic view of Fig. 1.
Specific implementation mode
Embodiment 1
A kind of centrifugal stopper for balancer provided in this embodiment, structure is as depicted in figs. 1 and 2, including from
One end of moving axis 6, brake rotor 1, bearing block 2 and brake arm 3, driven shaft is connected by sunk screw 7 with brake rotor,
Bearing block 2 is installed by screw 9 on the outside of brake rotor, the mounting hole on bearing block passes through pivotal mounting connection brake arm
One end is equipped with neck bush 4 between pivot and bearing block, washer 8 is equipped between brake arm and bearing block；Brake arm is around brake
The other end of arcuate structure on the outside of vehicle rotor, brake arm is connected by extension spring 10 with brake rotor, in brake arm and axis
It holds the connected outside of block and is equipped with boss, braking is contacted with brake ring inner bore of part 11 by boss；Brake arm connection stretches bullet
One end of spring is equipped with multiple spring mounting and adjustings hole.
When the present embodiment operates, driven shaft 6 receives the torque around axial line, entire centrifugal stopper assembly component around
Axial line rotates, and is now in work state（Linear velocity≤3m/s）.When entire centrifugal stopper assembly component turns around axial line
For moving-wire speed in 3~5m/s, brake arm 3 generates centrifugation, brake around the axial line of part pivot 5 under the influence of centrifugal force
3 the top boss of arm contacts with the endoporus of brake ring and generates leverage, so that entire centrifugal stopper is stopped operating, simultaneously
Also hoisting mechanism is made to move upwards stopping.Pass through the pulling force adjustment to 10 part of extension spring, thus it is possible to vary produced by brake arm 3
Centrifugal force size, and control its linear velocity and generate centrifugal action in 3~5m/s.
In addition to the implementation, the utility model can also have other embodiment.It is all to use equivalent replacement or equivalent change
The technical solution to be formed is changed, the protection domain of the requires of the utility model is all fallen within.
