Description
Technical field
The present invention relates to elevator car safety technical fields, and in particular to a kind of elevator safety gear.
Background technique
Currently, elevator applications are more and more extensive, great convenience is brought to life, so the safety of elevator there must be guarantor
Barrier.When promptly falling occurs in elevator, excessive velocities, elevator governor detection can drive rapidly safety tongs gripping elevator after exceeding the speed limit
Guide rail.Existing safe wrench structure is all complex, and manufacturing cost is high.
Summary of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of structure is simply electric
Terraced safety tongs.
The purpose of the present invention can be achieved through the following technical solutions: a kind of elevator safety gear, two lateral edges of the elevator
Guide rail move vertically, the safety tongs includes the friction plate that every guide rail two sides are arranged in, solid with every piece of friction plate back side
Surely the wedge shaped pushing block connected, the push rod for pushing pushing block and the power unit for driving push rod movement, when needing to make
When dynamic, power unit pushes pushing block to move toward one another by push rod, so that friction plate tightly embraces guide rail, completes braking.
The top view cross section of the pushing block is in a rectangular trapezoid, and side corresponding to upper bottom edge is fixedly connected with friction plate, institute
Push rod is stated to be slidably connected with side corresponding to bevel edge.
Horizontally disposed sliding slot is equipped in the middle part of side corresponding to the bevel edge.
The push rod is in T shape, including two are mutually perpendicular to and horizontally disposed straight-bar, and wherein the both ends of No.1 straight-bar are set
There is the sliding block to match with sliding slot, and is slidably connected in the sliding slot of two pushing blocks, one end and the No.1 straight-bar of No. two straight-bars
Center is fixedly connected, and the other end is connect with power unit.Since pushing block is in a rectangular trapezoid, and sliding slot is set on bevel edge, so
When push rod pushes forward, sliding block is wanted to move inward along sliding slot, but since the length of No.1 straight-bar can not change, so two
Pushing block can only be close to each other, so that friction plate be pushed to hold guide rail tightly, plays braking action.
The power unit include driving motor, the horizontal direction being connect with driving motor main shaft rotation driving wheel, with
The driven wheel that driving wheel is connected by chain and two drive rods being fixedly connected with chain, the other end of every drive rod with
Push rod is fixedly connected.
The drive rod and the linear chain between driving wheel and driven wheel connect, and two drive rod difference
It is connect with two straightways of chain.
The drive rod is L-shaped, and wherein a line is fixedly connected with chain, and another a line is fixedly connected with push rod.
Compared with prior art, the beneficial effects of the present invention are embodied in:
(1) structure is simple, by the pushing block of wedge shape, so that friction plate tightly embraces guide rail, good braking effect；
(2) the power unit powerful selected, and cost is relatively low.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of friction plate of the invention, pushing block and push rod；
Fig. 2 is the structural schematic diagram of power unit of the present invention.
Wherein, 1 is friction plate, and 2 be pushing block, and 3 be sliding slot, and 4 be sliding block, and 5 be No.1 straight-bar, and 6 be No. two straight-bars, and 7 be electricity
Machine, 8 be driving wheel, and 9 be driven wheel, and 10 be chain, and 11 be drive rod.
Specific embodiment
It elaborates below to the embodiment of the present invention, the present embodiment carries out under the premise of the technical scheme of the present invention
Implement, the detailed implementation method and specific operation process are given, but protection scope of the present invention is not limited to following implementation
Example.
Embodiment 1
A kind of elevator safety gear connects including the friction plate of every guide rail two sides is arranged in, fixes with every piece of friction plate back side
The wedge shaped pushing block connect, the push rod for pushing pushing block and the power unit for driving push rod movement.
Wherein, the top view cross section of pushing block 2 is in a rectangular trapezoid, and side corresponding to upper bottom edge is fixedly connected with friction plate 1,
Push rod is slidably connected with side corresponding to bevel edge, and horizontally disposed sliding slot 3 is equipped in the middle part of side corresponding to pushing block bevel edge.It pushes away
Bar is in T shape, including two are mutually perpendicular to and horizontally disposed straight-bar, and wherein the both ends of No.1 straight-bar 5 are equipped with and 3 phase of sliding slot
The sliding block 4 matched, and be slidably connected in the sliding slot 3 of two pushing blocks 2, one end of No. two straight-bars 6 and the center of No.1 straight-bar 5 are fixed
Connection, the other end connect with power unit, and specific structure is set on bevel edge as shown in Figure 1, since pushing block 2 is in a rectangular trapezoid
Set sliding slot 3, so pushing forward when push rod, sliding block 4 is wanted to move inward along sliding slot 3, but due to the length of No.1 straight-bar 5 without
Method changes, so two pushing blocks 2 can only be close to each other, so that friction plate 1 be pushed to hold guide rail tightly, plays braking action.
The structure of power unit is as shown in Fig. 2, the horizontal direction rotation for including driving motor 7, connecting with 7 main shaft of driving motor
The driving wheel 8 turned, two drive rods for passing through the driven wheel 9 that connect of chain 10 with driving wheel 8 and being fixedly connected with chain 10
11, the other end of every drive rod 11 is fixedly connected with No. two straight-bars 6.
Drive rod 11 and the linear chain 10 between driving wheel 8 and driven wheel 9 connect, and two drive rods 11
It is connect respectively with two straightways of chain 10, in Fig. 2, when driving wheel rotates clockwise, chain 10 can also turn clockwise
Dynamic, so No. two straight-bars 6 that will push left side move downward, and No. two straight-bars 6 on the right move right.
Drive rod 11 is L-shaped, and wherein a line is fixedly connected with chain 10, and another a line is fixedly connected with No. two straight-bars 6.
