Abstract
The utility model relates to a strong wheel pulling device, which consists of a shelf bracket, force claws, a lead screw and a pressing lever, wherein the force claw is connected to each corner of the shelf bracket; a central hole is formed in the center of the shelf bracket; the lead screw is arranged in the central hole; internal threads which are matched with external threads of the lead screw are formed in the central hole; and the pressing lever is arranged on the top of the lead screw. The strong wheel pulling device is small in volume, can be used at any maintenance place, and operated in places of which the operating areas are less than 2 meter<2>, and is convenient to use and easy to operate; and the strong wheel pulling device is operated by two persons, and the output force is about 5 T, so most of wheel type parts of which the diameters are more than 300 millimeters and less than 550 millimeters can be pulled out.
Description
Technical field
The utility model belongs to the flight-line maintenance technical field, relates in particular to a kind of pulley extractor.
Background technology
All exist large-scale rotary machine in industrial and mining enterprises and flight-line maintenance industry, all exist the wheeled parts that all size varies in size in the rotary machine, such as belt phoresys wheel, connects wheel, gear, bearing etc.And these wheeled parts are in maintenance process, and a little bit smaller service worker can use some simple, light small-sized pulley extractors to pull out according to field condition; So large-scale wheeled parts have just bothered a little, and particularly diameter is greater than the parts of 300mm, want to pull out must employ hydraulic press and pull out, but hydraulic press are bulky, is difficult for moving, and is difficult to arrive the working site, is unfavorable for maintenance.
The utility model content
The utility model problem to be solved provides the powerful pulley extractor that a kind of body is less, power output is big.
Adopt following technical scheme in order to solve the problems of the technologies described above: a kind of powerful pulley extractor; Form by A-frame, power pawl, leading screw and pressure thick stick; All joining on each angle of A-frame has a power pawl, and the A-frame center is provided with centre bore, and leading screw is arranged in the centre bore; The internal thread that matches with the leading screw external screw thread is arranged in the centre bore, and the leading screw top is provided with the pressure thick stick.
The pawl of said power pawl lower end colludes the plane and is provided with anti-expansion screw.
The utility model volume is little, can arrive any maintenance place, and work area is only just enough put to good use less than 2m2; Easy to use, be easy to just can go up hand operated; By 2 people's operations, power output has more than the 5T, can pull out most diameters greater than 300mm, less than the wheeled parts of 550mm.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
As shown in Figure 1, a kind of powerful pulley extractor is made up of A-frame 1, power pawl 2, leading screw 5 and pressure thick stick 6; All join on each angle of A-frame 1 a power pawl 2 is arranged; The pawl of power pawl 2 lower ends colludes the plane and is provided with anti-expansion screw 3, and A-frame 1 center is provided with centre bore 4, and leading screw 5 is arranged in the centre bore 4; The internal thread that matches with leading screw 5 external screw threads is arranged in the centre bore 4, and leading screw 5 tops are provided with presses thick stick 6.
