Description
Technical field
The utility model relates to a kind of mining power shovel maintenance tool, particularly a kind of WK-4 type power shovel cart band-type brake bottom dowel pin extracting tool.
Background technology
Mining power shovel is mainly used in outdoor ore shipment aspect.Wherein, cart part undertakes scraper bowl lifting work, belongs to power shovel elevator system; Cart band-type brake belongs to power shovel lifting system brake device, acts frequently, and brake rubber block is easy to wear, often changes; Existing replacing brake rubber block mode need remove band-type brake bottom dowel pin, there is not easily detachable feature, embodies a concentrated expression of alignment pin present position narrow and small, and damper brake is due to tension set, and existing tool ejector is inconvenient, and there is the danger destroying other parts.
Utility model content
The purpose of this utility model is to provide a kind of WK-4 type power shovel cart band-type brake bottom dowel pin extracting tool, solve cart band-type brake bottom dowel pin present position narrow, not easily detachable problem, avoid conventional tool dismounting difficulty of knowing clearly, the hidden danger of other parts of destructible, realizes power shovel cart band-type brake brake rubber block and changes easy, quick.
In order to achieve the above object, the utility model provides a kind of WK-4 type power shovel cart band-type brake bottom dowel pin extracting tool, comprise tapered head spiral jackscrew and spiral jackscrew pedestal, described tapered head spiral jackscrew is made up of the hexagonal (hexagon)nut on anterior conical head, rear threads bar, threaded rod; Described spiral jackscrew base interior has blind screw hole, the screw thread of blind screw hole and the screw thread of rear threads bar suitable, outside is provided with spanner card rib.
Described spiral jackscrew pedestal outer shape is prismatic.Preferably six prisms.
Beneficial effect: solve cart band-type brake bottom dowel pin present position narrow, not easily detachable problem, also avoid conventional tool dismounting difficulty, the hidden danger of other parts of destructible, realizes power shovel cart band-type brake brake rubber block and change easy, quick.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of tapered head spiral jackscrew;
Fig. 2 is the sectional view of spiral jackscrew pedestal;
Fig. 3 is the axial view of spiral jackscrew pedestal;
Fig. 4 is position, band-type brake place schematic diagram;
Fig. 5 is utility model works view;
Wherein: the anterior conical head of 1-, 2-hexagonal (hexagon)nut, 3-rear threads bar, 4-blind screw hole, 5-secondary axle, 6-reduction box, the left brake rubber block of 7-band-type brake, the right brake rubber block of 8-band-type brake, 9-brake cylinder, 10-alignment pin, 11-band-type brake.
Detailed description of the invention
As shown in Figure 1, tapered head spiral jackscrew is made up of rear threads bar 3, hexagonal (hexagon)nut 2, anterior conical head 1, and spiral jackscrew base interior has a common blind screw hole 4, and there is spanner card rib outside; Rear threads bar 3 and blind screw hole 4 form threaded engagement, and hexagonal (hexagon)nut 2 is screwed on rear threads bar 3, and rear threads bar 3 screws in blind screw hole 4, by rotating hexagonal (hexagon)nut 2, increasing conical head jackscrew flight, completing axial thrust effect.
As shown in Figure 4, after WK-4C type power shovel cart band-type brake is positioned at the reduction box 6 of elevator system secondary axle 5, band-type brake left brake rubber block 8 bottom end is connected with brake cylinder 9, is fixed in bottom base bottom the right brake rubber block 7 of band-type brake by alignment pin 10.Cart braking procedure is by brake cylinder 9 action, drags the left brake rubber block 8 of band-type brake, makes left and right brake rubber block hold brake hub tightly simultaneously, forms the braking of secondary axle 5 circumference, realizes the braking of power shovel elevator system.
The brake rubber block of band-type brake belongs to consumable accessory, need often change.When changing brake rubber block, left and right brake rubber block must be dismantled nested; Need remove bottom dowel pin 10 when dismounting the right brake rubber block is nested, alignment pin 10 is band tapering articulation hole circular shaft pin, and pivot pin one end is spacing by the shaft shoulder, and the other end is spacing by bearing pin in articulation hole; Alignment pin circular cone articulation nose end is positioned at deceleration pusher side.
Alignment pin tradition dismounting mode utilizes the tool ejector such as ripping bar, tup, and because position is narrow, the nested tension force effect of brake rubber block, alignment pin is to not easily stressed, and dismounting is difficult, and easy damaged brake rubber block is nested.The utility model makes according to the feature invention that alignment pin present position is narrow.During use, regulate the helical pitch of tapered head spiral jackscrew, as Fig. 5, make the cone pinnacle of anterior conical head 1 in alignment pin locating and machining hole, spiral jackscrew pedestal leans on reduction box 6 shell, the spanner catching edge part blocking spiral jackscrew pedestal with spanner divides (conveniently spanner clamping, whole spiral jackscrew pedestal outer shape is all made prismatic, hexagon, is equivalent to a long hex nut greatly), be supported on installation horizontal plane, prevent from rotating; Block hexagonal (hexagon)nut 2 with another spanner to rotate, increase the helical pitch of rear threads bar 3, increase alignment pin axially loaded, make alignment pin axial displacement, when rear threads bar helical pitch reaches detent fit length, alignment pin departs from positioning pedestal, completes dismounting.
The utility model overcomes narrow, the not easily detachable difficulty of alignment pin position, solve the difficult problem that conventional tool not easily realizes, for maintenance band-type brake, change the brake rubber block saving plenty of time, realize WK-4 type power shovel elevator system long-period stable operation, and the utility model instrument can repeated multiple timesly use, simple to operate, safety.
