Abstract
The utility model relates to an oil refill device for a corrugation expander, which comprises a force bearing beam. Two lifting holes are symmetrically arranged on the force bearing beam, a lead screw penetrates respectively through each lifting hole, an upper nut is installed on the lead screw of one side of the force bearing beam, the lead screw of the other side of the force bearing beam is provided with a connecting structure for fixing with an end cover of the corrugation expander. The oil refill device for the corrugation expander utilizes the nuts and the lead screws to lift the corrugation expander, meets the requirement for oil refill operation, not only has simple structure, is convenient to use, but also greatly enhances reliability and use safety.
Description
Technical field
The utility model relates to electric power special tool field, particularly a kind of recharging oil device that is used for bellow expander.
Background technology
The patent No. is that the Chinese patent of ZL200820139123.3 discloses a kind of corrugated metal expander repairing special tool, form by support, rising dish etc., stent support is on the base of corrugated metal expander, the rising dish is provided with rocking handle, card wheel and rising wick, raising, rope one end is connected with rocking handle, the other end is connected with the upper end cover of corrugated metal expander, and support and rising dish are bolted to connection.By shaking rocking handle, roll the rising wick, and then lifting expander upper end cover, and fixing with the card wheel.It is complicated operation, a large amount of manpowers of needs and equipment, ineffective problem that this scheme has solved corrugated metal expander repairing.But this mode complex structure, the parts that need are a lot, and the reliability of serving mode, safety are not high.
The utility model content
The purpose of this utility model provides a kind of recharging oil device that is used for bellow expander, in order to solve the problem of existing repairing tool construction complexity, poor reliability.
For achieving the above object, scheme of the present utility model is: a kind of recharging oil device that is used for bellow expander, comprise a bearing beam, symmetry offers two and promotes the hole on the bearing beam, each promotes Kong Zhongjun and is equipped with screw mandrel, be equipped with upper nut on the screw mandrel of described bearing beam one side, the screw mandrel of bearing beam opposite side is provided with and is used for being fixedly coupled structure with the bellow expander end cap.
Adopt repairing instrument of the present utility model, utilize nut and screw mandrel bont to promote bellow expander, meet the requirement of repairing operation, not only simple in structure, easy to use, and also reliability and safety in utilization have also improved greatly.
Further, described connection structure comprises and bellow expander end cap negative thread bonded assembly screw mandrel one end, and on lower nuts.Described lifting hole is vertical slotted hole.Be provided with pad between described screw mandrel and the upper nut.Described bearing beam is an angle bar.The fuel filler pipe that described bearing beam is provided with oil hole on the corresponding bellow expander end cap passes the hole.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
The utility model is described in more detail below in conjunction with accompanying drawing.
Bellow expander as shown in Figure 1 and repairing instrument thereof, the repairing instrument comprises a bearing beam, bearing beam can be channel-section steel or angle bar, adopt angle bar 4 herein, with 4 in angle bar on expander shell 6, symmetry offers the slotted hole 8 of two long 10cm on the angle bar 4, vertically wear a screw mandrel 1 in each slotted hole 8, screw mandrel 1 lower end fixedly is screwed onto on the bellow expander end cap 5 by a lower nuts, also be equipped with upper nut 2 on the screw mandrel 1, upper nut 2 is positioned at angle bar 4 upsides, is provided with pad 3 between nut 2 and the angle bar 4.The fuel filler pipe that angle bar 4 central authorities have oil hole on the corresponding end cap 5 passes the hole.
During use, fix angle bar 4, two screw mandrels 1 are passed from slotted hole 8, adjust the position, lower end and expander end cap 5 are spirally connected and tighten, with spanner dextrorotation turn nut 2, nut 2 is extruding angle bar 4 downwards, but since 4 in angle bar on expander shell 6, can not move down, so screw mandrel 1 meeting upward movement, and drive the fixing expander lifting in its lower end.Rise to the appropriate location, the fuel filler pipe that fuel filler pipe is passed angle bar 4 central authorities passes the hole and connects oil hole 7 on the end cap 5, can carry out repairing work.The meaning that slotted hole 8 is set is, can make this instrument be fit to the bellow expander of multiple model.
