Abstract
A pusher comprises a main body and a connector adapting to the main body, wherein the main body comprises a handle, a pushing mechanism, a straight rod and a positioning mechanism; the straight rod is transversely arranged on the main body in a penetrating manner; the pushing mechanism is movably connected with the straight rod and can be controlled to push the straight rod to move forward; the positioning mechanism is movably connected with the straight rod to lock or unlock the position of the straight rod; a notch matched with the connector is formed in the front end of the main body. A pushing plate is driven by pressing a pushing handle on the main body to move in the length direction of the straight rod; under the action of a friction (the friction is larger than a pressure exerted by the positioning mechanism), the straight rod is driven to move forward; the pusher can be used for pushing a pull rod during maintenance of a compressor, and is simple, convenient, time-saving and labor-saving in operation.
Description
Technical field
The present invention relates to compressor maintenance tool field, particularly a kind of pusher.
Background technology
Piston type ammonia refrigerating compressor generally includes following components:
A. motion parts: comprise bent axle, connecting rod, piston etc.;

The specific embodiment
Below the invention will be further described by the specific embodiment.
With reference to Fig. 1, Fig. 2, a kind of pusher, comprise main body 1 and adaptive joint 2 with it, main body 1 comprises one handle 11, a pushing mechanism, a straight-bar 12 and a location mechanism. be formed through a thrust zone 13 about main body 1 middle part, main body 1 front end also offers the breach 14 suitable with joint.Handle 11 is positioned at this thrust zone 13 belows, and straight-bar 12 is horizontally through this thrust zone 13.Straight-bar 12 cross sections are that hexagon and its front end are provided with round end section 15, and the rear end is provided with hand and grabs section 16.Be positioned at thrust zone 13 both sides in main body 1 and also be respectively equipped with the reinforcement 17 that distributes along straight-bar 12 length directions, be used for strengthening the intensity of main body 1.
Pushing mechanism comprises a pushing handle 21, a push pedal 22 and one first elastic component 23.Push pedal 22, pushing handle 21 tops and the first elastic component 23 are positioned at this thrust zone 13, and this pushing handle 21 is rotationally connected with main body 1 by a rotating shaft 24, and rotating shaft 23 is positioned at these thrust zone 13 belows and position, handle 11 boundary.This push pedal 22 is sheathed on the straight-bar 12 and with pushing handle 21 tops and is flexibly connected, and this first elastic component 23 also is sheathed on the straight-bar 12 and opens and peaks between push pedal 22 and the main body 1.With reference to Fig. 3, Fig. 4, when controlling pushing handle 21 relative handle 11 action, push pedal 22 is driven moves along straight-bar 12 length directions, and under the effect of frictional force (this frictional force is greater than the detent mechanism applied pressure), driving straight-bar 12 moves forward, when stop operation, push pedal 22 is return under the effect of the first elastic component 23, and the position of straight-bar 12 remains unchanged under the effect of detent mechanism.
Detent mechanism is used for the position of locking or release straight-bar 12, comprise a pressing plate 31, one second elastic component 32 and a fixed leg 33, fixed leg 33 is fixed in main body 1 rear end, pressing plate 31 is arranged on the straight-bar 12 and an end and 33 flexible connections of this fixed leg, 32 of the second elastic components peak at and order about pressing plate 31 inclinations between pressing plate 31 and the main body 1, produce pressure by the 31 pairs of straight-bars of pressing plate 12 that tilt and lock straight-bar 12 positions, with reference to Fig. 5, when pressing these pressing plate 31 other ends and make pressing plate 31 and straight-bar 12 vertical, the pressure of 31 pairs of straight-bars 12 of pressing plate disappears, thereby release straight-bar 12, the hand that can hold straight-bar 12 this moment are grabbed section 16 straight-bar are pulled out.
Joint 2 one ends are provided with two sections screwed pipes 3 that radius is different, and the other end is provided with the connecting portion 4 suitable with main body breach 14, main body breach 14 are set for trapezoidal, and these corresponding connecting portion 4 cross sections also are trapezoidal, and connecting portion 4 bottoms also are provided with limiting section 41.
When the present invention can be used for the auxiliary repair compressor, connect to promote the pull bar in the compressor, observe the valve block trend when being used for dress suction valve chip and valve seat, or check whether pull bar is flexible, or whether normally put in place during dress cylinder pressure lid.This pull bar is connected with oil connection or the chock plug of outside, adopts aforesaid impeller operated step as follows:
1) oil connection or chock plug are pulled down, replaced joint oil connection or chock plug to be connected with pull bar;
2) the pusher front end is docked with joint so that the pole front end buckles in the joint;
3) pull the pressure pushing handle so that straight-bar moves forward with hand, repeat to pull and press for several times;
4) according to the needs of maintenance step, press pressing plate, this moment, straight-bar was rebounded under the pull bar effect;
5) repeating step 3) and 4) repeatedly advance or rebound with pusher of the present invention, in order to allow the required step of maintenance personal's observe and decide, as observe cylinder jacket and whether match with the pull bar of main frame, whether the little push rod of cylinder is flexible, also have suction valve chip whether to move up and down etc., judge the maintenance step of concrete needs according to actual conditions.
During such as overhaul, mainly be that cylinder cap is taken apart, crankcase cover is taken apart, cylinder jacket and piston are taken apart, the related pull bar of oil pipe oil circuit and oil cylinder place position checks (being comprised of oily piston, spring and pull bar in the oil cylinder), that is to say that maintenance need to be torn valve seat, valve block, cylinder, connecting rod, piston open each time.Some type need to be torn cylinder cap open and spur valve group.Indispensable effect when at this moment pull bar just plays assembling.
Adopt pusher of the present invention to cooperate maintenance to compare with tradition and can save time about one hour, save time and laborsaving.
Above-mentioned only is a specific embodiment of the present invention, but design concept of the present invention is not limited to this, allly utilizes this design that the present invention is carried out the change of unsubstantiality, all should belong to the behavior of invading protection domain of the present invention.
