Abstract
A pin shaft pulling-out device comprises a jacking tool and a connecting piece, wherein the jacking tool is connected with the connecting piece through a high-strength bolt, and the connecting piece is fixed on a pin shaft to be dismounted through the high-strength bolt; the cross-section of the jacking tool is of a T-shaped structure, two ends of a horizontal plane of the jacking tool are respectively connected with a jack, the connecting piece is a welding assembly and comprises a bottom plate and two main plates, the two main plates are welded on the bottom plate in parallel and vertically, a threaded hole is formed in the middle of the bottom plate, and a connecting hole is formed in the upper portion of each main plate. The device can not damage the part which is buried underground and can be used for continuing to remove the old part, namely the protective removing part, in the pulling-out process of the pin shaft, and has the advantages of simple structure, convenient use and low manufacturing cost.
Description
Technical field：
The utility model belongs to a kind of equipment Removal equipment, more particularly to a kind of bearing pin extracting apparatus.
Background technology：
In production line overhaul, transformation process, because the time is short, task weight, Party A typically can select to leave to be embedded in underground
The part (protective demolition) that reuses can be continued, change aerial part equipment (destructiveness is removed), and this two parts is often by bearing pin
Connection, so how to extract the bearing pin and turn into the key of engineering success or failure not injury protection does not remove part.
The content of the invention：
The purpose of this utility model, which is that, overcomes above-mentioned the deficiencies in the prior art, and provides a kind of bearing pin and extract
Device, it will not damage in the withdrawal process of bearing pin being embedded in underground and can continue the part i.e. protective demolition portion that reuses using the device
Point, and simple in construction, easy to use, low manufacture cost.
As above conceive, the technical solution of the utility model is：A kind of bearing pin extracting apparatus, it is characterised in that：By top tool and
Connector is formed, and top tool is connected with connector by high-strength bolt, and connector is fixed on bearing pin to be torn open by high-strength bolt；Institute
The section for stating top tool is " T " shape structure, and on top, the horizontal plane both ends of tool are connected to jack, and the connector is a weldering
Assembly, including one piece of bottom plate and two pieces of mainboards are connect, two pieces of mainboards are parallel and are vertically welded in substrate, are formed among bottom plate
Screwed hole, mainboard top are formed with connecting hole.
Thickness δ=50mm of above-mentioned bottom plate.
Side plate is connected between the two sides of above-mentioned two pieces of mainboards.
The utility model has the following advantages and good effect：
1st, the utility model raw material scene is readily obtained, and is made simply, conveniently；
2nd, stress relief hole when the utility model needs to process bearing pin when in use carries out tapping, then with high-strength bolt
II is connected, and can so avoid destroying bearing pin.Simultaneously as bearing pin and connector are screwed connections, so direction can
Arbitrarily to adjust；
3rd, the utility model top tool is connected with connector using high-strength bolt I, can be had rotation, can thus be kept away
Exempt to cause extraction bearing pin to there is card to relate to phenomenon because jack strength is uneven.
Brief description of the drawings：
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of top tool；
Fig. 3 is the structural representation of connector.
Embodiment：
As shown in the figure：A kind of bearing pin extracting apparatus, it is made up of top tool 1 and connector 2, top tool and connector pass through high-strength spiral shell
Bolt 8 is connected, and connector is fixed on bearing pin 10 to be torn open by high-strength bolt 9.The section of the top tool is " T " shape structure, is being pushed up
The horizontal plane both ends of tool have set up jack 3 respectively, and the connector is one and welds assembly, including one piece of bottom plate 4 and two
Block mainboard 5, two pieces of mainboards are welded on substrate, and screwed hole 6 is formed among bottom plate, and mainboard top is formed with connecting hole 7.Two pieces of masters
Side plate 11 is connected between the both sides of plate, mainly plays reinforcement effect, the A/F of connector is thick with steel plate selected by top tool 1
Degree matching.Thickness δ=50mm of above-mentioned bottom plate.
Application method of the present utility model is：
1st, mantle fiber is carried out using the stress relief hole removed when being processed among bearing pin, screw thread specification will be with high-strength bolt 9
It is identical；
2nd, connector is fixed on above bearing pin to be torn open using high-strength bolt 9；
3rd, top tool is connected with connector high-strength bolt 8；
4th, jack is set up using top tool both sides to carry out extracting bearing pin work.
