Abstract
The invention relates to an oil supplementing device for a bellows expander, which comprises a bearing beam. The bearing beam is symmetrically provided with two lifting holes. Screw rods are respectively inserted in each lifting hole. The screw rod at one side of the bearing beam is provided with an upper nut, and the screw rod at the other side of the bearing beam is provided with a connection structure for being fixed with an end cover of the bellows expander. After an oil supplementing tool is adopted, the bellows expander is lifted through a nut and screw lifting device and the requirements of the oil supplementing operation are met. Not only does the oil supplementing device have simple structure and is convenient to use, but also the reliability and the using safety are also greatly improved.
Description
Technical field
The present invention relates to electric power special tool field, especially for the recharging oil device of 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, rising wick 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.
Summary of the invention
The purpose of this invention is to provide the 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, the solution of the present invention is: the 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 invention, 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 a structural representation of the present invention.
Concrete enforcement side
The present invention will be further described in 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.
