Specific embodiment
Illustrate a specific embodiment of the invention below.
As shown in Figure 1 and Figure 2, mechanical Multipoint synchronous loading device includes several load(ing) points with hydraulic actuator
The hydraulic actuator of component, adjacent load point component is connected by threeway 12 with hydraulic oil pipe 13, hydraulic in the present embodiment to hold
Units use hydraulic cylinder 8, the inlet of adjacent hydraulic cylinder 8 pass through the second hydraulic oil pipe 132 connection threeway 12, each three
Logical 12 connect commonly through first hydraulic oil pipe 131, in the outlet of the inlet and hydraulic pump 16 of the first hydraulic oil pipe 131
Connection.In being also respectively connected to pressure gauge 14 and valve switch 15 on the first hydraulic oil pipe 131.
The specific structure of load(ing) point component is as follows:
Load(ing) point component includes chain 1, lever support 4, lever 5 and conduit 7, and lever support 4 and conduit 7 weld, lever 5
It is assembled with lever support 4 by lever support bolt 3, one end of lever 5 stretches out lever support 4 and passes through chain bolt 2 and chain
One end pin joint of item 1, the other end of lever 5 also stretch out lever support 4 and are socketed with thimble sliding block 11, open up on thimble sliding block 11
First for cooperating lever 5 is open.Thimble sliding block 11 and sliding block 10 pass through 9 pin joint of sliding block bolt, open up screw thread on sliding block 10
Hole is opened up for cooperating the second of thimble sliding block 11 to be open on sliding block 10, and the second opening makes sliding block 10 form U-shaped sliding block.Above-mentioned U
There is gap between shape sliding block and thimble sliding block 11.One end end of hydraulic actuator and screw hole, it is hydraulic to execute member
The other end of part protrudes into conduit 7.In being additionally provided with graduated scale 6 on lever 5.It can be along the notch of conduit 7 between above-mentioned hydraulic execution member
Make straight-line displacement.
Specific work process of the invention is as follows:
As shown in Figure 1 to Figure 3, according to the status requirement of carrier frame load(ing) point, each load(ing) point component is placed in carrier frame
The other end of the lower section of frame 17, each chain 1 is connect with the tooling of carrier frame 17, then that hydraulic cylinder 8 and first is hydraulic
Oil pipe 131 and the connection of the second hydraulic oil pipe 132, so that load(ing) point component be made to connect in place with carrier frame.
Needing load value to be offered according to each load(ing) point of the requirement of load working condition, i.e. the value of thrust of chain 1 is F1,
F2, F3... Fn (n is load(ing) point quantity).The pressure of series connection oil circuit can be set as P according to pressure gauge 14, and each hydraulic oil
The piston rod area of cylinder 8 is S, then hydraulic cylinder 8 is capable of providing thrust N (wherein N=P × S), due to lever chain end power
Arm is A, then according to lever principle, when thimble sliding block 11 is adjusted to corresponding arm of force value according to graduated scale 6 on lever 5
As shown in Figure 1 to Figure 3, it before each load, needs to level on the lever 5 in load(ing) point component, and thimble sliding block
11 are moved to the distance calculated, and hydraulic cylinder 8 is moved to U-shaped 10 lower section of sliding block along conduit 7, by one end spiral shell of hydraulic cylinder 8
Line portion is tightened with U-shaped sliding block 10.Since sliding block 10 and thimble sliding block 11 have a gap, sliding block 10 and thimble sliding block 11 it
Between rotated by sliding block bolt 9.Start hydraulic pump 16 slowly to pressurize, after pressure gauge 14 reaches specified numerical value P, closes valve switch
15, pressure keeps numerical value P in oil circuit, and the pulling force at chain 1 also reaches specified numerical value, and carrier frame 17 subjects test load,
And keep wanting seeking time simultaneously, after reaching specified time, hydraulic pump 16 is closed, valve switch 15 is slowly opened, is made first hydraulic
The pressure of hydraulic oil gradually decreases down zero in oil pipe 131 and the second hydraulic oil pipe 132, and single load operating condition terminates.When need into
When other load conditions of row, need to readjust thimble sliding block 11 relative to the position between lever 5.
The configuration of the present invention is simple, easy to use, operation are easy, and the loaded value of each load(ing) point can be disclosed not with load respectively
With being adjusted, effectively increase loading accuracy and working efficiency, while also reducing security risk so that investment and use at
This is lower.
Above description is explanation of the invention, is not intended to limit the invention, and limited range of the present invention is referring to right
It is required that the present invention can make any type of modification without prejudice to basic structure of the invention.
