Abstract
The utility model discloses an embedded wheel puller, which comprises a screw. The embedded wheel puller is characterized in that the embedded wheel puller also includes an arc-shaped cluck; external threads are formed on the screw wall; a round hole is disposed at the top end of the screw rod; a threaded hole with internal threads is disposed on the arc-shaped chuck; the screw rod is mounted in the threaded hole through the threads and can extend to the arc-shaped chuck; an opening is formed on the non-arc-shaped surface of the arc-shaped chuck; and a round hole is formed on the outer side of the arc-shaped surface of the arc-shaped chuck. The embedded wheel puller solves the problems of the prior wheel puller, such as complex structure, complex use, low work efficiency, and the possible damage to the edge of a stroke wheel. The contact area between the wheel puller and the brim of the stroke wheel of the motor is increased so as to reduce the pressure on the force-bearing point. Through thread transmission, the embedded wheel puller can stably detach the stroke wheel of the motor by one man without the need of a hydraulic jack, and has the advantages of convenient operation and high work efficiency.
Description
Technical field
The utility model relates to a kind of device of the strokes per minute wheel of choosing, and particularly relates to a kind of embedded pulley extractor.
Background technology
In normal machine driving; many power sections are arranged by the transmission of strokes per minute wheel; particularly at large-scale oil pump; water pump; in the machineries such as oil pumper; when changing the machine work mode, will pull up motor strokes per minute wheel; in addition in the pumpingh well working equipment; because breaking down, the strokes per minute wheel also needs the strokes per minute wheel is transferred to from machine shaft; existing pulley extractor is that two pawls or three-pawl type are fixed; the center is that leading screw is shored; the precession leading screw; extract the strokes per minute wheel, there is following shortcoming in this pulley extractor: 1; motor is worked in the open, exposes to the weather to drench with rain; cause motor wheel shaft rust dead; pulley extractor pulling claw and motor strokes per minute wheel tread are long-pending less in addition, have increased the pressure of stress point, therefore motor strokes per minute wheel rim often occurs and are pulled off; phenomenons such as the pulley extractor pulling claw comes off; strokes per minute wheel is damaged scrap, and change strokes per minute wheel inefficiency and cause long downtimes stopping production, increased entreprise cost.The pulling claw that falls down sometimes in operating process simultaneously even can injure the staff exists bigger potential safety hazard.2, when motor strokes per minute wheel and motor gap were too small, pulley extractor can't use.3, pulley extractor is provided with hydraulic jack, complex structure, and inefficiency if there is not hydraulic jack, can't be extracted the strokes per minute wheel again.
The utility model content
In order to solve pulley extractor complex structure in the prior art, use loaded down with trivial detailsly, inefficiency damages the problem at strokes per minute wheel edge easily, and it is a kind of simple in structure, easy to use that the utility model provides, and can not cause the embedded pulley extractor of strokes per minute wheel damage of edges.
In order to achieve the above object, technical solution adopted in the utility model is:
A kind of embedded pulley extractor, comprise leading screw, it is characterized in that: also comprise the circular arc chuck, described screw mandrel wall is provided with external screw thread, is provided with screwed hole on the circular arc chuck, is provided with internal thread in the screwed hole, screw mandrel is installed in the screwed hole by threaded engagement, and can stretch in the circular arc chuck, the non-arcwall face of described circular arc chuck is provided with opening, is provided with circular hole in the circular arc chuck arcwall face outside.
Aforesaid a kind of embedded pulley extractor is characterized in that: the perforate direction of described circular hole parallels with the opening direction of circular arc chuck.
Aforesaid a kind of embedded pulley extractor is characterized in that: be provided with circular hole in the circular arc chuck arcwall face right-hand member outside.
Aforesaid a kind of embedded pulley extractor is characterized in that: described leading screw top is provided with circular hole.
The beneficial effects of the utility model are: the utility model has changed the pulling claw of pulley extractor into chuck, increased the contact area of pulley extractor and motor strokes per minute wheel rim, reduced the pressure of stress point, exerted pressure, motor strokes per minute wheel is steadily unloaded by the screw thread transmission, in production application, guaranteed not damage strokes per minute wheel wheel edge, strokes per minute wheel serviceability rate reaches 100%, can not cause personnel's damage because of the landing of pulling claw simultaneously, safe and reliable, long service life.And the utility model is simple in structure, and is easy to operate, need not use hydraulic jack to finish field-strip, can people's complete operation, and working strength is little.High efficiency.The utility model, also can use when too small in motor strokes per minute wheel and motor gap in addition, and the scope of application is big.
Description of drawings
Fig. 1 is a front view of the present utility model;
Fig. 2 is a vertical view of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As depicted in figs. 1 and 2, a kind of embedded pulley extractor comprises leading screw 1 and circular arc chuck 2, and the circular arc of circular arc chuck 2 can be half cycle type or big half cycle type.Screw mandrel 1 wall is provided with external screw thread, and leading screw 1 top is provided with circular hole 7, is provided with perforate on circular arc chuck 2, and the center line that is provided with screwed hole 3, two holes at the top of perforate is relative.Be provided with internal thread in the screwed hole 3, the external screw thread of the internal thread of screwed hole 3 and leading screw 1 is suitable, leading screw 1 is installed in the screwed hole 3 by threaded engagement, and can stretch in the circular arc chuck 2, the non-arcwall face of described circular arc chuck 2 is provided with opening 4, be provided with circular hole 6, more convenient like this operating personnel's rotational circle arc chuck 2 in the circular arc chuck 2 arcwall faces 5 right-hand members outside.The perforate direction of described circular hole 6 parallels with opening 4 directions of circular arc chuck 2.
During use, the circular arc chuck 2 of inserted type pulley extractor is blocked the strokes per minute wheel, and make leading screw 1 inside rotation extend into circular arc chuck 2, leading screw 1 is withstood the motor reel core, use two poles to insert respectively in circular hole 6 and the circular hole 7, left hand utilizes pole to prop up circular hole 7, the right hand utilizes the pole circular hole 6 that turns clockwise, can drive the rotation of circular arc chuck 2 like this, the strokes per minute wheel can be rotated on the screw mandrel 1 of embedded pulley extractor from motor rotary shaft by rotation, after strokes per minute wheel extracted, be rotated counterclockwise again the strokes per minute wheel is taken out from screw mandrel 1.
Show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
