Specific implementation mode
The present invention is described further below in conjunction with attached drawing：
The present invention includes brake unit and connecting rod operating mechanism 1, and brake wheel and clamp arm 2 are provided in brake unit, brake
Wheel, which is fixedly mounted on, to be needed on the brake axle 7 braked, the clamp arm 2 altogether there are two, two clamp arm 2 are hinged and connected to form one
Circular ring structure with opening, the inside of clamp arm 2 are fixed with brake rubber block 3, and when brake, two clamp arm 2 are in connecting rod operating mechanism 1
Brake wheel locking is realized the braking to brake wheel, that is, realizes the braking to pumping unit from outside under driving.It is existing skill above
Common structure in art, details are not described herein.
The brake wheel is divided into 4 two parts of inner ring 5 and outer ring, and outer ring 4 is sleeved on inner ring 5 and can be around the axis of inner ring 5
Rotation, inner ring 5 is fixedly mounted on brake axle 7, and the edge of 5 side of inner ring is equipped with gear 9, the inside of outer ring 4 be provided with
The gear teeth 6 of gear engagement.Under braking state, the rotary shaft of gear 9 is turned by spanner or other tools to drive gear 9 to revolve
Turn, the outer ring 4 of brake wheel is fixed under the constraint of clamp arm 2, and the inner ring 5 of brake wheel rotates under the driving of gear 9, gear
It is rotated together around the axis of brake axle 7 with inner ring 5 while 9 rotation, the inner ring 5 of rotation drives brake axle 7 to rotate, and then realizes
Adjustment to shutdown of pumping machine posture provides a great convenience for the maintenance and inspection of pumping unit.
The side of the inner ring 5 is additionally provided with the two-way check component for blocking gear 9.The two-way check component
Including a shifting block 11 and two struts 8, shifting block 11 and strut 8 are hinged on the inner ring 5, and two struts 8 are symmetrically set
It sets in the both sides of shifting block 11, the free end of two struts 8 keeps close to shifting block 11 under the action of spring 10 respectively
Movement tendency, when shifting block 11 is placed in the middle, the free end of two struts 8 is against the side of a tooth of the gear 9, at this time gear
9 is rotatable, can be by the 8 fragmented gear 9 of strut of corresponding side, to release corresponding strut 8 to tooth after shifting block 11 is turned to side
The inhibition of 9 rotation of wheel.
Two-way check component can make the inner ring 5 of brake wheel and outer ring 4 keep opposing stationary in brake process, in guarantee
Circle 5 and outer ring 4 are checked simultaneously, to ensure the validity of braking.Meanwhile shutdown pose adjustment after brake process
In the process, two-way check component can prevent rotation gear 9 reversion (and no matter gear 9 rotate clockwise or counterclockwise revolve
Turn, all have anti-reverse effect), to ensure the controllability of the rotation of inner ring 5 during shutting down pose adjustment, it is further ensured that
Safe operation.
It is both provided with wavelike structure on the outside of the inside of the clamp arm 2, the both sides of brake rubber block 3 and brake wheel, is stopped
The wavelike structure of 3 both sides of railway carriage is matched with the wavelike structure on clamp arm 2 and brake wheel respectively.After 2 locking of clamp arm, mutual
Face of two couple matched with wavelike structure is bonded to each other, and brake drag compared with prior art greatly increases, meanwhile, even if folder
Arm 2 will not all be occurred to beat by pico- expansion outward after the reaction force of brake wheel as long as the range of expansion is in the reasonable scope
Sliding phenomenon, therefore, wavelike structure can not only ensure the validity of braking, and it is possible to prevente effectively from occur " to slip after brake
Vehicle " phenomenon produces the technology effect of simplified brake device structure to eliminate the braking safety device in existing brake gear
Fruit.
The brake rubber block 3 is made of rubber material, of low cost, and it is convenient to replace.
The wave at the wavelike structure edge is by the 12 end to end spelling of radian and the arc section of radius all same
At, if two endpoints connection of arc section 12 is surrounded arch with straightway, the ratio between the bowed height and chord length are not more than
1:6.These technical characteristics constrain the shape of the wave in wavelike structure, and reason is：When above-mentioned ratio mistake
When big, wavelike structure is excessively prominent, and machinery is vibrated big when can cause to lead to the problem of long braking time and brake, and right
The size of wavelike structure, which carries out limitation, can effectively solve both of these problems.
