Specific implementation mode
One embodiment of the utility model is described further below in conjunction with the accompanying drawings.
A kind of urgent complemental brake system for JD-2.5 car haulers as shown in Figure 1, including winch base 1, system
Driving wheel 2, brake arm 4, spring cavity 21, electro hydraulicthruster 17 and manual brake 10, braked wheel 2 are located at winch base 1
Top, 2 both sides of braked wheel are equipped with brake shoes 3, and brake shoes 3 is connect with brake arm 4, and brake arm 4 is equipped with the first axis pin 5, braking
4 both sides of arm are respectively connected with a block pressur plate 7 by the first axis pin 5, and 4 upper end of brake arm is connected with rear plug 6, and 6 right end of rear plug connects
It is connected to U-shaped lower plug 9,9 middle part of U-shaped lower plug is equipped with the second axis pin 8, and the medium position of two block pressur plates 7 is located at the second axis pin 8
Top, U-shaped 9 lower end of lower plug are connected with pull rod group, and pull rod group includes upper connecting rod 15, lower pull rod 27, adjusting nut 18, nut 13
With two pieces of chucks 19,15 both ends of upper connecting rod are screw thread, and lower 27 upper end of pull rod is screw thread, and lower end is step, upper connecting rod 15 with it is U-shaped
Lower plug 9 is connected by nut 13, upper and lower pull rod（15、27）It is connected by nut 13 and adjusting nut 18, lower 27 lower end of pull rod
It is connected with fork set 22, fork set 22 is equipped with third axis pin 23, and two pieces of chucks 19 are located on lower pull rod 27 and are located at adjusting nut 18
Between third axis pin 23, buffer spring 20 is equipped between two pieces of chucks 19, fork set 22 passes through third axis pin with manual brake 10
23 connections；1 side of winch base is equipped with support base 26, and electro hydraulicthruster 17 is arranged by pusher base 24 in support base
On 26, the push rod on electro hydraulicthruster 17 is connect with the right end of two block pressur plates 7；Spring cavity 21 is set by spring cavity pedestal 25
It sets on support base 26 and between electro hydraulicthruster 17 and winch base 1, compressed spring 16 is equipped in spring cavity 21,
It is connected with spring pull rod 14 in compressed spring 16, sets that there are one both ends to be rectangular pressure among circle among two block pressur plates 7
Block 12, briquetting 12 are equipped with through-hole, and spring pull rod 14 connect with briquetting 12 and locked by locking nut 11.
In normal operation, winch motor and electro hydraulicthruster 17 are in energized state, and power hydraulic pressure pushes
Device 17 is released push rod by thrust, and the pressing plate 7 being attached thereto is moved upwards using 5 center of the first axis pin as basic point, under disengaging is U-shaped
The second axis pin 8 on plug 9, while pressing plate 7 drives spring pull rod 14 to move upwards, compressed spring 14 is in and is further compressed
State.Since pressing plate 7 has been detached from 8 a distance of the second axis pin at this time, manual brake 10 is in and both may be used at this moment
Declutch but can brake state, do not influenced by electro hydraulicthruster 17 and pressing plate 7.
When winch overloads, power-off or other reasons all can be by the magnetic starters that mine side is installed when electric current being caused to increase
Current limliting thermorelay device makes winch motor and 17 motor of electro hydraulicthruster power off, at this time 17 thrust of electro hydraulicthruster
It disappears, and compressed spring 16 had been constantly in compressed state in the past, under the brake force of compressed spring 16, spring was forced to draw
Bar 14 moves downward, while being moved downward with dynamic pressure plate 7, and pressing plate 7 drives U-shaped lower plug 9 downward while oppressing the second axis pin 8
Movement, and upper connecting rod 15 and lower pull rod 27 is driven to move downward, compressed simultaneously in buffer spring 20,19 lower face of chuck makes
Fork set 22 rotates down.Since manual brake 10 and fork set 22 are fixedly linked by third axis pin 23, so can be with third pin
23 center of axis rotates down for basic point, can regard manual brake 10 as and also make brake braking maneuver, to play emergency braking
Purpose.
After 17 normal power-up of winch motor and electro hydraulicthruster, 17 push rod of electro hydraulicthruster boosts, pressing plate 7
It is detached from the second axis pin 8, and due to the effect of ratchet in winch hand brake system, manual brake 10 brakes shape still in brake
State needs manually above to push away manual brake 10 at this time if wanting to make niggerhead normal rotation（It declutches）, braked wheel 2 could take off
From 3 strap of the brake of brake shoes, the safety coefficient of winch is improved again in this way.
