Background technology:
At present, the drg that present existing mine hoist adopts adopts the radially version of band-type brake more, and heavy volume is big, commonality is poor.Its inertia is big, the slow motion adjustability is poor, complex structure, can't realize and exchange that maintenance is adjusted inconvenient general.
Summary of the invention:
In order to overcome the deficiencies in the prior art, the utility model provides a kind of novel gig special-purpose disc-brake, produces lock torque by adopting clamping elevation scheme Moving plate, realizes the braking of gig.
For achieving the above object, the utility model adopts following technical scheme:
The special-purpose disc-brake of this novel gig is made up of brake shoe, disk spring, hydraulic package, shell liner and braking body; Its braking body is structure in the form of a ring, and an end is equipped with shell liner in the braking body, and shell liner is connected by bolt with brake shoe; The other end is equipped with brake cylinder in the braking body, and the brake cylinder housing is built-in with the hydraulic oil pipeline, and the brake cylinder ring is built-in with piston, and the hydraulic oil pipeline is communicated with oil pocket; Piston is connected by seal ring with brake cylinder; Piston is captiveed joint by fastening bolt with the cylindrical shell of shell liner; The outer end face of brake cylinder compresses with disk spring and is connected, and the other end and the oil cylinder cover of brake cylinder are tightly connected, and the brake cylinder ring is outer captives joint with adjustment nut, adjustment nut and the screwed connection of braking body; And fix by lock screw; Pressing plate on the shell liner is fixed together itself and brake shoe by bolt.
The special-purpose disc-brake of this novel gig, its shell liner is connected to form by cylindrical shell and guide, and cylindrical shell is built-in with disk spring, cylindrical shell cylindrical and the interior sliding block joint of braking body, cylindrical shell is captiveed joint by pressing plate with brake shoe.
The special-purpose disc-brake of this novel gig, its oil cylinder cover cylindrical one end is equipped with the pipeline opening of hydraulic oil, and the turnover of pressure oil is a passage; Hydraulic oil pipeline on its oil cylinder cover end face aligns by the seal ring captive joint with the hydraulic oil pipeline of brake cylinder end face, and in addition, the oil pocket outside is provided with seepage oil passage, collects presumable oil impregnate specially.
Owing to adopt aforesaid technical scheme, the utlity model has following preceence:
The special-purpose disc-brake of this novel gig is the execution unit of brake system, adopts oil pressure to open oil cylinder mechanism, and disk spring compression cylinder mechanism realizes, the size of braking force determine reduce in oil pressure what; Its effect is to guarantee gig when needs slow down or stop, and brake equipment acts on brake disc with braking force, gig is steadily slowed down or stops; Have that volume is little, in light weight, inertia is little, action is fast, adjustable type is good, reliability is high, highly versatile, simple in structure, the maintenance levelling is convenient.
Description of drawings:
The special-purpose dish type brake structural of the novel gig of Fig. 1 scheme drawing.
Shown in Fig. 1: the 1-brake shoe; The 2-shell liner; 3-brakes body; The 4-brake cylinder; The 5-piston; The 6-fastening bolt; The 7-seal ring; The 8-oil cylinder cover; The 9-adjustment nut; The 10-lock screw; The 11-disk spring; The 12-pressing plate; 13-hydraulic oil pipeline; 14-pressure hydraulic fluid port; 15-seepage hydraulic fluid port; The 16-oil pocket.
The specific embodiment:
As shown in fig. 1: the special-purpose disc-brake of this novel gig; Having brake shoe, disk spring, hydraulic package, shell liner and braking body forms; Its braking body (3) is structure in the form of a ring, and an end is equipped with shell liner (3) in the braking body, and shell liner (2) is connected by bolt with brake shoe (1); The other end is equipped with brake cylinder (4) in the braking body, and the brake cylinder housing is built-in with hydraulic oil pipeline (13), and the brake cylinder ring is built-in with piston (5), piston and brake cylinder decomposition pressure oil pocket (16), and the hydraulic oil pipeline is communicated with oil pocket; Piston is connected by seal ring (7) with brake cylinder; Piston is captiveed joint by fastening bolt (6) with the cylindrical shell of shell liner; The outer end face of brake cylinder compresses with disk spring (11) and is connected, and the other end of brake cylinder and oil cylinder cover (8) are tightly connected, and the brake cylinder cylindrical is captiveed joint with adjustment nut (9), adjustment nut and the screwed connection of braking body; And it is fixing by lock screw (10); Pressing plate on the shell liner (12) is fixed together itself and brake shoe by bolt.
The special-purpose disc-brake of this novel gig, its shell liner is connected and composed by cylindrical shell and guide, and cylindrical shell is built-in with disk spring, cylindrical shell cylindrical and the interior sliding block joint of braking body, cylindrical shell is captiveed joint by pressing plate with brake shoe.
The special-purpose disc-brake of this novel gig, its brake cylinder is structure in the form of a ring, and an end is equipped with the hydraulic oil pipeline in the brake cylinder housing, and its oil cylinder cover cylindrical one end is equipped with the pressure hydraulic fluid port (14) of hydraulic oil, and the other end is equipped with the seepage hydraulic fluid port (15) of hydraulic oil; Hydraulic oil pipeline on its oil cylinder cover end face aligns by the seal ring captive joint with the hydraulic oil pipeline of brake cylinder end face.
During installation, these parts have several independent disc-brakes to be fixed in couples on the support with bolt, produce lock torque by adopting clamping elevation scheme Moving plate, realize the braking of gig.
During work, disk spring provides braking force, provides high pressure oil to realize declutching by Hydraulic Station.When the high pressure oil that transports from Hydraulic Station entered oil pocket, piston just drove brake shoe and leaves brake disc, and disk spring is to compression, and brake shoe and brake disc have just had the gap, and drg just is in the state of declutching.When the high pressure oil pressure of oil pocket slowly reduces, under the spring force effect of disk spring, the brake shoe close and applying to brake disc gradually, when oil pressure is reduced to minimum, the positive pressure that acts on the brake disc reaches maxim, brake shoe and brake disc are exactly the braking force of gig work with the frictional force that produces, and gig will be in the braking mode of normal operation.
