Specific implementation method
Below in conjunction with specific embodiment, the present invention is described in detail.Following examples will contribute to those skilled in the art and understand the present invention further, but not limit the present invention in any form.It should be pointed out that to those skilled in the art, without departing from the inventive concept of the premise, some distortion and improvement can also be made.These all belong to protection scope of the present invention.
Shown in Fig. 1 ~ Fig. 5, balancer weight retinue braking device provided by the present invention, comprise mechanical structure and electrical control two large divisions, mechanical structure portion comprises balancing weight 1 and braking brake mechanism, linked together by balancing weight and mounting box connecting bolt 7 and upper plate connecting bolt 8, become a whole machine balancing weight.Therefore the weight of balancer weight comprises standing part (Quick brake) and adjustable part (balancing weight).
Balancing weight 1 is the identical steel disc in cross section, by the combination of different-thickness, can make balancer weight quality step-less adjustment in the accuracy rating of 10g.Balancing weight cross section and fast braking braking mechanism match, and there is through hole corner, be connected easily or dismantle by bolt with braking brake mechanism.Configuration block 1 liang of opposite side is designed with groove, and steel wire 10 can be made to pass through and not produce interference.
Braking brake mechanism is made up of push-pull electromagnet 3, mounting box 2, wedge-shaped blocks 5 and push rod 4.Electromagnet 2, wedge-shaped blocks 5 and push rod 4 are arranged in mounting box 2.Mounting box 2 has electromagnet wire guide 12.Wedge-shaped blocks 5 is drilled with tapped hole, can fixes with the threaded stem of electromagnet 3, and require that adjustment is screwed into the degree of depth according to movement travel.Push rod 4 is arranged in spacing hole, makes one dimensional motion extruded cords 10 under the promotion on wedge-shaped blocks inclined-plane.Steel wire 10 is designed with corresponding threaded hole of steel 6, and it mainly contains two functions: one is lead by steel wire 10 in mechanism deploying process, to reduce rocking of balancer weight; Two is that fast braking brake relies on the friction between steel wire 10 and push rod 4 to realize Quick brake function.
