Abstract
The utility model discloses a special pulling device used in equipment installation and maintenance works, which comprises guide screws, a base, a pulling apparatus and a jack; wherein the base and the pulling apparatus are connected as a whole by two guide screws, the jack is horizontally arranged on the base, and the surface of the jack is in contact with the pivot bracket surface of the component to be pulled. The pulling device consists of two half parts which are symmetrical and are tightly fixed by two butted bolts, and the middle part is provided with stair round orifice in which sleeve gaskets are arranged. According to the characteristics of object to be pulled, by choosing an appropriate jack, a sleeve gasket with proper specification and guide screws with proper length, the pulling device can satisfy the requirements of disassembling the interference-fit elements such as upper bearings, coupling and the like on common shaft diameter. Practices prove show that the pulling device has the advantages of simple structure, convenient assembly and disassembly, high safety and reliability, and strong practicability, and is capable of greatly shortening the man-hour for examining and fixing the equipment and improving work efficiency, so the special pulling device can be widely used in equipment installation and maintenance works.
Description
Technical field
The utility model relate to a kind of having of on rotary machine equipment, using pull bearing, to the detaching device of parts such as wheel, impeller, specifically be a kind ofly to utilize the special use of jack work to pull device.
Background technology
At present, the medium-sized rotary machine equipment of domestic many enterprises is when repairing, need to change some parts, as bearing, to wheel, impeller etc., bearing, wheel is belonged to interference fit with the connection of rotating shaft, remove very difficulty, remove with common device for drawing die, the maintainer is very hard, and damages device for drawing die easily, and work brings very big inconvenience to repair and maintenance.
Summary of the invention
The utility model is at the problem that exists in the above equipment repair dismounting, development and design also provides a kind of simple in structure, easy to operate special use to pull device, the special use that can be used as the rotary machine maintenance pulls device, for the quick field-strip equipment of repair and maintenance personnel provides reliable assurance.
The technical scheme that its technical problem that solves the utility model adopts is:
This special use pulls device, comprises leading screw, base, dismounting apparatus and jack.Described base is connected one with dismounting apparatus by two rhizoid thick sticks, and jack is flat on the base, and the jack end face contacts with the spindle nose surface of drawing part.
Described dismounting apparatus is the two halves of symmetry, docks fastening one by two bolts, and there is the ladder circular hole at the middle part, is provided with spacer in the ladder circular hole.
Described base is fixedlyed connected by four nuts at two rhizoid thick sticks and its two ends with dismounting apparatus.
According to by being pulled features of the object, rationally select jack, spacer specification and leading screw length for use, can satisfy general diameter of axle upper bearing (metal), to the dismounting of interference fit parts such as wheel.
Facts have proved that the utility model is simple in structure, easy to loading and unloading, safe and reliable, practical, can shorten man-hour of repair apparatus greatly, increase work efficiency, can extensive use in equipment installation and maintenance engineering.
Description of drawings
Fig. 1 is a front view of the present utility model;
Fig. 2 is a left view of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
As shown in the figure, this special use pulls device and by two rhizoid thick sticks 3, four nuts 6 oval-shaped base 7 and dismounting apparatus 1 is linked into an integrated entity, and places jack 5 on the base 7, can constitute this special use and pull device.
The dismounting apparatus 1 of this device is the two halves of symmetry, to clamping solid one, regulates the specification of spacer 8 and the length of leading screw 3 according to the size reasonable of part 2 or axle 4 diameters by two bolts, can satisfy
The following diameter of axle upper bearing (metal) of 120mm, to the dismounting of interference fit parts such as wheel.
Pull the bearing of interference fit on the dismounting diameter of axle, during to parts such as wheels, on 7 of jack 5 bottom surfaces placement bases, jack 5 end faces are contacted with spindle nose 4 surfaces of drawing part 2, the back side that the dismounting apparatus 1 and the spacer 8 of symmetrical halves is enclosed within the part that draws again, with the fastening one of bolt and nut, adjust jack 5 and put in place, can pull the required part that pulls on the diameter of axle.
Consider the particularity of some part installation sites, can select for use according to actual conditions to add long lead screw.
