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 Special purpose tools for oil compensation of ripple glaze metal expansion device, by support, rising dish etc., formed, stent support is on the base of corrugated metal expander, 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 rising wick, and then lifting expander upper end cover, and fixing with card wheel.It is complicated operation that this scheme has solved tools for oil compensation of ripple glaze metal expansion device, need a large amount of people's force-summing devices, ineffective problem.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 object of this invention is to provide the recharging oil device for bellow expander, in order to solve the problem of existing oil compensating tool complex structure, poor reliability.
For achieving the above object, the solution of the present invention is: for the recharging oil device of bellow expander, comprise a bearing beam, on bearing beam, symmetry offers two lifting holes, in each lifting hole, be all equipped with screw mandrel, on the screw mandrel of described bearing beam one side, be equipped with upper nut, the screw mandrel of bearing beam opposite side be provided with for the fixing connection structure of bellow expander end cap.
Adopt oil compensating tool of the present invention, utilize nut and screw rod lifting device 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 the screw mandrel one end being connected with bellow expander end cap negative thread, and on lower nuts.Described lifting hole is longitudinal slotted hole.Between described screw mandrel and upper nut, be provided with pad.Described bearing beam is an angle bar.Described bearing beam is provided with the fuel filler pipe of oil hole on corresponding bellow expander end cap through hole.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
specific embodiment party
Below in conjunction with accompanying drawing, the present invention will be further described in detail.
Bellow expander as shown in Figure 1 and oil compensating tool thereof, oil compensating tool comprises a bearing beam, bearing beam can be channel-section steel or angle bar, adopt angle bar 4 herein, by 4, angle bar on expander shell 6, the symmetrical slotted hole 8 that offers two long 10cm on angle bar 4, in each slotted hole 8, vertically wear a screw mandrel 1, screw mandrel 1 lower end is fixedly screwed onto on bellow expander end cap 5 by a lower nuts, on screw mandrel 1, be also equipped with upper nut 2, upper nut 2 is positioned at angle bar 4 upsides, between nut 2 and angle bar 4, is provided with pad 3.Angle bar 4 central authorities have the fuel filler pipe of oil hole on corresponding end cap 5 through hole.
During use, fix angle bar 4, two screw mandrels 1 are passed from slotted hole 8, adjust 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 because 4, angle bar is on expander shell 6, can not move down, so screw mandrel 1 meeting upward movement, and drive the fixing expander in its lower end to promote.Rise to appropriate location, the fuel filler pipe that fuel filler pipe is passed to angle bar 4 central authorities connects the oil hole 7 on end cap 5 through hole, can carry out repairing work.The meaning that slotted hole 8 is set is, can make this instrument be applicable to the bellow expander of Multiple Type.
