Embodiment Construction
[0015] The preferred embodiments of the present invention will be described in detail below in conjunction with the drawings.
[0016] Such as figure 1 , 2 As shown, the synchronous braking system of the suspended excavator includes two brake discs 13 and two oil cylinders 25. The front of the brake disc 13 is a friction surface, and the back is attached to and fixedly connected to the inner end surface of the inner sleeve 12. The outer sleeve 11 is sleeved on the outer sleeve of the inner sleeve 12, and the inner sleeve 12 and the outer sleeve 11 can face each other. slide. The outer sleeve 11 is fixed on the connecting frame 26, and the outer end surface of the inner sleeve 12 is fixedly connected to the pull rod 21. The pull rod 21 is sleeved with a compression spring 14 which is compressed between the inner sleeve 12 and the outer sleeve 11. . The pull rod 21 is connected by a lever 23, a connecting rod 24 and a piston rod 27 of the cylinder 25. The lever 23 is provided wi...

The invention discloses a synchronous braking system for a suspended type digger, which comprises two brake discs and two cylinders, wherein the front side of each brake disc is a friction surface, and the back side of each brake disc is supported against a pressure spring and is connected with a pull rod; the friction surfaces of the two brake discs are arranged relatively; and the other end of the pull rod is connected with a piston rod of the cylinder. During use, the system is fixedly connected with a chassis of the digger, and the two brake discs are arranged on the two sides of an I-beamguide rail; when the digger digs, the brake discs make the friction surfaces compress the I-beam guide rail under the pressure action of the pressure spring; the friction force between a brake disc of a brake on the digger and the I-beam guide rail overcomes the counter acting force generated when a main body of the digger digs and prevents the main body of the digger from moving; and when the digger needs to move, the pull rods of the brake discs are pulled by operating a travel hydraulic motor and synchronously providing hydraulic oil for the cylinder, and the pressure of the pressure spring is overcome to make the brake discs loosened; therefore, the digger can move back and forth and is used quite conveniently.
Description
Technical field [0001] The invention relates to a suspension excavator, in particular to a synchronous braking system of the suspension excavator. Background technique [0002] In the construction process of deep foundation pneumatic caisson, unmanned remote control hydraulic excavator is generally used for excavation. The machine is installed in a closed pneumatic caisson. Through the monitoring system installed in the machine and the caisson, the operator is remotely controlled in the ground control room The system controls the excavator in the caisson. Due to the limited working space in the caisson, it is best to use a suspended excavator. The main body of the excavator is suspended on the I-steel rail on the top plate through movable guide wheels. Driven by the driving device, the excavator can follow the I-steel rail. Move back and forth, while the working arm of the excavator stretches out to dig the ground. [0003] However, because the suspended excavator is suspended on...
