Detailed description of the invention
Attached drawing is used to provide further understanding of the present invention, and constitutes part of specification, with reality of the invention
It applies example to be used to explain the present invention together, not be construed as limiting the invention.In the accompanying drawings:
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is the A of Fig. 1 to enlarged structure schematic diagram.
Mark component: 12 first screw rod of handle, 3 fixed link, 45 second screw rod of threaded sleeve, 6 cushion block, 7 first platform
8 11 horizontal conveyor bar of fixed plate 9 second platform board, 10 hydraulic hand-pump of plate, 12 cart.
Specific embodiment
Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.
Extra-high-voltage alternating current transformer oil-immersed pump replaces specific purpose tool, as Figure 1-Figure 2, including cart 12, cart 12
A hydraulic hand-pump 10 is installed in top two sides respectively, and the fixing end of hydraulic hand-pump 10 is connect with cart 12, hydraulic hand-pump
Platform is lifted in 10 lift side connection, and the platform of lifting includes the second platform board 9, and the two sides of the second platform board 9 are connected and fixed
Plate 8, the side of fixed plate 8 connect the first platform board 7, and 9 place plane of the second platform board is lower than 7 place plane of the first platform board,
First platform board 7 of 9 two sides of the second platform board cooperates with two hydraulic hand-pumps 10 respectively, and the two sides of cart 12 are respectively mounted several
Auxiliary stabilizing device, the auxiliary stabilizing device include threaded sleeve 4, and threaded sleeve 4 is tool internal thread tubular structure, spiral shell
The outside of line casing 4 is connect with the side of cart 12, and threaded sleeve 4 is connected through a screw thread the first screw rod 2, the first screw rod 2 it is upper
Cushion block 6 is installed in end connection handle 1, the lower end of the first screw rod 2, and cushion block 6 can cooperate with ground.
The present invention increases several auxiliary stabilizing devices in the two sides of cart 12, replaces position when cart 12 reaches target oil-immersed pump
When being replaced, the first screw rod 2 of auxiliary stabilizing device can be moved down by way of swing handle 1 by operator,
To drive cushion block 6 to resist bottom surface with certain pressure, the wheel of cart 12 is made to be detached from ground, to avoid cart 12 latent in replacement
It is slided during oil pump, improves extra-high-voltage alternating current transformer oil-immersed pump replacement specific purpose tool when carrying out oil-immersed pump replacement
Stability.
The scope of application, specific implementation selection and feasibility analysis: we are made the sample of actual fabrication with Figure of description
For drawing, the ratio of all parts and fit system are implemented in attached drawing to specifications, and the connection is strength adhesive company
It connects, weld, riveting, the common connection type such as flanged joint, integrated molding formula connection, it can be according to actually connecting when actual fabrication
Intensity is connect to need without the creative thickness and intensity for selecting corresponding connection type, tie point.
The lower end of first screw rod 2 is connected and fixed bar 3, and the lower end of fixed link 3 connects the second screw rod 5, the second screw rod 5
Lower end connects cushion block 6, and the second screw rod 5 can be threadedly coupled with threaded sleeve 4.
We have found in actual use, if being combined as the stabilization of cart 12 using threaded sleeve 4 and the first screw rod 2 merely
Device, needing to rotate the first screw rod 2 when in use, much circle can allow cushion block 6 to resist ground, and in order to solve this point, we contract
Short first screw rod 2 of crude oil increases fixed link 3 in 2 lower end of the first screw rod, fixed link 3 can 4 inside of threaded sleeve freely
Sliding, from the adjustment length that can shorten the first screw rod 2 when needing cushion block 6 resisting ground, keeps fixed link 3 direct
6 fast approaching of cushion block resists the position of bottom surface when by sliding in threaded sleeve 4, and then user makes the first screw rod 2 manually
It is threadedly coupled with threaded sleeve 4, in the way of the first screw rod 2 of rotation, is lifted auxiliary stabilizing device by cart 12, avoids pushing away
Vehicle 12 generates sliding when replacing oil-immersed pump.When needing 12 position of mobile handcart, the first screw rod 2 and threaded sleeve 4 can be made
Threaded connection state is released, pulls the first screw rod 2 to be threadedly coupled the second screw rod 5 with threaded sleeve 4 then up, to avoid
Cushion block 6 and ground face contact interfere the sliding of cart 12 on the ground.
Horizontal conveyor bar 11, the both ends difference of horizontal conveyor bar 11 are connected between the handle of described two hydraulic hand-pumps 10
It is connect with the handle of two hydraulic hand-pumps 10.
Horizontal conveyor bar 11 of the invention can be convenient operator's manual operation once can be with the hand-hydraulic of Yadong two
The handle of pump 10 is improved to two hydraulic hand-pumps 10 so that two hydraulic hand-pumps 10 be enable to be adjusted in synchronism lift side
Operating efficiency.
