Specific embodiment
The following further describes the present invention with reference to the drawings:
The composition of brake apparatus.
As shown in Figure 2, brake block 2 is made of wedge-shaped friction block 21, latch segment 22, friction plate 23.
As shown in Figure 3, accumulator 3 is made of accumulator extrusome 31, accumulator cylinder 32 and compressed spring 33.
As shown in Figure 4, trigger device 4 is by master control wirerope 41, buffering tension spring 42, wirerope connecting plate 43, sub-control steel
Cord 44, leading block 45 form.
Before brake apparatus installation, lifting means should be placed in a support platform, and boom hoist cable is in certain
Relaxed state in range.
The assembly of accumulator 3.
Compressed spring 33 is placed among accumulator extrusome 31 and accumulator cylinder 32 and is compressed, by locking ear 34
Accumulator extrusome 31 and accumulator cylinder 32 are locked with bolt, are combined into an entirety.
The installation of brake apparatus.
Brake apparatus pedestal 1 is fixed by bolts on lifting means.
Friction plate 23 is screwed on wedge-shaped friction block 21, latch segment 22 is fixed by bolts to brake apparatus base
On seat 1, wedge-shaped friction block 21 is connect with accumulator 3.
Accumulator cylinder 32 is fixed on latch segment 22 using articulated manner, 31 one end of accumulator extrusome and wedge shape are rubbed
Cleaning block 21 is articulated and connected, and the other end and trigger device 4 connect；After completing above-mentioned connection, the bolt locked on ear 34 is unloaded,
Accumulator extrusome 31 pops up, will be in the wedge-shaped friction block 21 that be attached thereto press to guide rail.
The sub-control wirerope 44 connecting with 31 one end of accumulator extrusome is passed through into wirerope connecting plate 43 and buffering tension spring
42 connect with master control wirerope 41, and 41 other end of master control wirerope is connected with chain sling.
The two states of brake apparatus.
After completing above-mentioned installation, loose boom hoist cable is tensed, be connected to master control wirerope 41 on chain sling by
Pulling force, each sub-control wirerope 44 being attached thereto while under tension, the accumulator extrusome 31 being connected with sub-control wirerope 44
Drive the wedge-shaped friction block 21 being attached thereto mobile, friction plate 23 thereon is separated with lifting means guide rail, final wedge shape friction
Block 21 is bonded with latch segment 22.This is the releasing state of brake apparatus.
In lifting means operational process, hoist ropes break, the master control wirerope 41 being connected on chain sling loses drawing
Power, the sub-control wirerope 44 being attached thereto while losing pulling force, force signal is passed to accumulator 3, in the effect of accumulator 3
Under, compressed spring 33 releases stress, and accumulator extrusome 31 is ejected, and the wedge-shaped friction block 21 being attached thereto is driven to set to promotion
Standby guide rail direction is mobile, and the friction plate 23 being fixed on wedge-shaped friction block 21 is expressed on lifting means guide rail, wedge shape friction
Friction plate 23 and lifting means guide rail on block 21 generate frictional force, in the case where lifting means is in disconnected rope free falling body state, wedge
Shape friction block 21 under two hinge joints effect of accumulator 3 with 22 relative motion of latch segment, in very short time, wedge-shaped friction block
21 are expressed between latch segment 22 and lifting means guide rail, since the material composition of friction plate 23 makes friction plate 23 and lifting means
The frictional force that guide rail is formed is very big, and under lifting means gravity, wedge-shaped friction block 21 and lifting means are formed and self-locking will be mentioned
Rise equipment braking.This is the on-position of brake apparatus.
