Abstract
The utility model discloses a kind of simple draw bench special, threaded push rod is connected with pedestal by screwed hole, two pull bars is machined with the second unthreaded hole, and pedestal is provided with the first unthreaded hole, the two is connected with connecting bolt respectively；High-strength bolt is connected with the screwed hole of workpiece surface by the 3rd unthreaded hole below pull bar.Advantage is only two pull bars, and every part can be dismantled, simple in construction, easy to maintenance；High strength exploitation workpiece and pull bar is used to bear pulling force, it is possible to the lower surface of protection workpiece.
Description
Technical field
This utility model relates to extracting tool field, particularly to a kind of for protecting the draw bench special of workpiece lower surface.
Background technology
Draw horse remove be applicable to rail truck maintenance, mechanical erection, mine are safeguarded, the support of architectural engineering and general weight rise
Rise outside decline is used, the round shape workpiece such as belt pulley in the most detachable various plant equipment, gear, bearing.Drawing of application at present
Horse it is generally required to be stuck in the lower surface of workpiece then by the countershaft transmission carrying out power of push rod thus by workpiece by the pulling claw of pull bar
Separate with axle.But after some workpiece is installed, its lower surface is work surface and don't can damage, at this moment this type workpiece
What dismounting just inconvenience use was traditional draw horse to carry out operating in order to avoid defective work piece lower surface.
Summary of the invention
The purpose of this utility model is to solve the above-mentioned deficiency drawing horse to exist, it is provided that one will not destroy workpiece lower surface
Simple draw bench special.
For achieving the above object, this utility model includes that push rod, pedestal, a pair pull bar, a pair connecting bolt and a pair are high
Strength bolts；Threaded push rod is connected with pedestal by screwed hole；Being machined with the second unthreaded hole on two pull bars, pedestal is provided with
First unthreaded hole, connects the two with connecting bolt respectively；High-strength bolt is by the 3rd unthreaded hole below pull bar and table on workpiece
The screwed hole in face connects.
Compared with drawing horse with tradition, the utility model has the advantage of:
1. the high-strength bolt being used for undertaking pulling force has positioning function, so this utility model only has two pull bars, often
A part can be dismantled, simple in construction, easy to maintenance；
2. the lower surface that tradition draws horse that pulling claw is stuck in workpiece operates, this utility model high strength exploitation work
Part and pull bar bear pulling force, it is possible to the lower surface of protection workpiece.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Fig. 2 is the cross section structure schematic diagram of pedestal of the present utility model.
Fig. 3 is the cross section structure schematic diagram of pull bar of the present utility model.
In figure: 1. push rod, 2. pedestal, 2-1. screwed hole, 3. connecting bolt, 4. pull bar, 5. high-strength bolt, 2-2. first
Unthreaded hole, 4-1. the second unthreaded hole, 4-2. the 3rd unthreaded hole.
Detailed description of the invention
As it is shown in figure 1, this utility model includes threaded push rod 1, pedestal 2, a pair pull bar 4, a pair connecting bolt 3 and
A pair high-strength bolt 5.Threaded push rod 1 is connected with pedestal 2 by screwed hole 2-1；As shown in Figure 2 and Figure 3, two pull bars
Being provided with the second unthreaded hole 4-1, pedestal 2 is provided with the first unthreaded hole 2-2, the two is connected with bolt 3 respectively, connecting bolt 3 herein
It is primarily subjected to shearing force；High-strength bolt 5 is connected with the screwed hole of workpiece surface by the 3rd unthreaded hole 4-2 below pull bar 4,
During work, high-strength bolt is primarily subjected to axial force.During operation, it is connected to workpiece with high-strength bolt 5 by the 3rd unthreaded hole 4-2
The screwed hole of upper surface, rotation push rod 1, until contacting with axle center below push rod 1, continues to rotate push rod 1, now high-strength bolt 5
Start to bear pulling force, until being separated from axle by workpiece.
