Embodiment
Supporting leg tester of the present invention, comprises bracing frame, and press mechanism is installed on bracing frame.Press mechanism is upwards connected with bracing frame.Bracing frame can hang on press mechanism supporting leg 19 tops, so that press mechanism applies downforce to supporting leg 19.The execution unit of press mechanism is connected with briquetting 12 downwards.Bracing frame is provided with vertical guiding mechanism, and guiding mechanism coordinates with briquetting 12, to 12 vertical guide effects of briquetting, guarantees that the useful effect of press mechanism applied pressure is on supporting leg 19, the working environment that test is realized closer to supporting leg 19.Can prevent to a certain extent supporting leg 19 lateral bendings simultaneously.
During detection, supporting leg 19 tops can be fixed on briquetting 12 by fixed pin 16, and the lower end of supporting leg 19 is firmly contacted with ground or support platform.Start press mechanism, press mechanism pressurizes to supporting leg 19 by briquetting 12, until supporting leg 19 during by compression failure, is recorded force value now, thereby can be obtained the actual bearing capacity of supporting leg.For realizing robotization control, described supporting leg tester can be equipped with one by console computer 24, so that staff carries out remote control and automatically manipulation, both can prevent from meeting accident in process of the test and accidentally injured staff, can accurately monitor whole process of the test again.
As shown in Figure 1 to Figure 3, support frame as described above can be connected and composed by guide upright post 15 and crossbeam 14.Guide upright post 15 is vertical guiding mechanism.Crossbeam 14 is connected with guide upright post 15.Press mechanism is connected and fixed by crossbeam 14 and bracing frame.Briquetting 12 is slidably matched with guide upright post 15, and guide upright post 15 play the guiding role to briquetting 12.A guide upright post 15 and a bracing frame that crossbeam 14 forms, when installing and using, the lower end of guide upright post 15 should be connected and fixed with ground, and crossbeam 14 should be fixed with wall connecting.
As shown in Figure 1 to Figure 3, bracing frame can comprise two guide upright posts 15, crossbeam 14 and a base 20.The bracing frame of this structure need not rely on body of wall while installing, and application is not subject to the restriction of using area, and fastness is better.
As shown in Figure 1, described press mechanism is the first hydraulic cylinder 13.The first hydraulic cylinder 13 is connected with bracing frame.The piston rod of the first hydraulic cylinder 13 is connected with briquetting 12 downwards.Described press mechanism can also be cylinder, linear electric motors or other actuating units that can exert pressure to briquetting 12.
For preventing that supporting leg 19 from lateral bending occurring in pressurized process, the authenticity that impact detects.As shown in Figures 1 to 3, on described briquetting 12, supporting leg clamp system is installed.Supporting leg clamp system can be connected and composed by fixed head 17 and driving mechanism, and driving mechanism is connected with briquetting 12.The execution unit of driving mechanism is connected with fixed head 17.Driving mechanism can drive the relative briquetting 12 of fixed head 17 to open or closure.Detect while preparing, when the relative briquetting 12 of fixed head 17 is opened, supporting leg 19 is put between briquetting 12 and fixed head 17; Afterwards, driving mechanism drives relative briquetting 12 closures of fixed head 17, and fixed head 17 coordinates clamping supporting leg 19 with briquetting 12.For more fastening clamping supporting leg 19, a set of clamp system can respectively be installed in the left and right sides of briquetting 12, and two clamp systems are symmetrical.Fixed head 17 can be to be fixedly connected with driving mechanism, can be also hinged.。As shown in Figure 4 and Figure 5, described driving mechanism is the second hydraulic cylinder 18 for the hinged scheme of fixed head 17 and driving mechanism.The second hydraulic cylinder 18 is hinged with briquetting 12, and its hinge axis is the first hinge axis 21; One end of the piston rod of the second hydraulic cylinder 18 and fixed head 17 is hinged, and its articulated axle is the second hinge axis 22; The middle part of fixed head 17 and briquetting 12 are hinged, and its hinge axis is the 3rd articulated axle 23.The piston rod of the second hydraulic cylinder 18 stretches can drive relative briquetting 12 swing opens of fixed head 17 or closure.The first hinge axis 21, the second hinge axis 22 are parallel with the 3rd articulated axle 23.As shown in Figure 4 and Figure 5, described fixed head 17 is provided with grasping teeth, so that firm grip supporting leg 19.
Due to the length difference of different model supporting leg, and the detection stroke of the briquetting 12 of described testing machine is fixed, therefore, for convenience of supporting leg 19 is installed in described testing machine and is detected, need following operation: first rotate supporting leg rocking bar 3 supporting leg 19 is shortened, after supporting leg 19 is fixing with briquetting 12, then rotates supporting leg rocking bar 3 supporting leg 19 is extended, so that the lower end of supporting leg 19 is stablized and contacted with ground or base 20.For automatically realizing said process, as shown in Fig. 6 to 8, on described briquetting 12, supporting leg driver is installed, supporting leg driver consists of detent mechanism and driver.Detent mechanism is connected with briquetting 12.The execution unit of detent mechanism is connected with driver, can drive driver near or away from supporting leg 19.The supporting leg rocking bar 3 that driver can be provided with supporting leg 19 is connected, and drives supporting leg rocking bar 3 to rotate, to realize elongating or shortening of supporting leg 19.Supporting leg driver improves the automaticity of described supporting leg tester, reduces manually-operated step.
As shown in Fig. 6 to 8, described detent mechanism can be connected and composed by lift beam 10, slide plate 6, slide rail 7, slide block 8 and cylinder 9.Lift beam 10 is installed on briquetting 12, slide rail 7 and cylinder 9 are installed on lift beam 10, the movable slide block 8 of installing on slide rail 7, slide block 8 is connected with slide plate 6, and slide plate 6 can move linearly along slide rail 7.The piston rod of cylinder 9 can be connected with slide plate 6 by cylinder jacking block 11; Installation of driver on slide plate 6.Briquetting 12 can drive detent mechanism synchronization lifting.Cylinder 9 can drive driver near or leave supporting leg rocking bar 3.Described detent mechanism can be also other existing mechanisms that drive driver to move, but its structure of detent mechanism as shown in Fig. 6 to 8 is the most succinct, and positioning precision is higher.
As shown in Fig. 6 to 8, described driver is motor 5.For convenience of motor 5 is connected with slide plate 6, mounted motor support 1 on slide plate 6.Described driver can be also oil motor.
For convenience of motor 5 is connected to cooperation with supporting leg rocking bar 3.As shown in Figure 6 to 8, on described motor 5, reductor 2 is installed, the input shaft of reductor 2 is connected with the output shaft of motor 5, and shaft coupling 4 is installed on the output shaft of reductor 2.It is more stable that reductor 2 can make supporting leg rocking bar 3 rotate.Reductor 2 and shaft coupling 4 can be installed rotation sensor, and when supporting leg 19 elongations drop to base 20, rotation sensor is to console computer 24 signals, and motor 5 quits work, and cylinder 9 drive motors 5 are separation with supporting leg rocking bar 3.Can sensor installation on the piston rod of the first hydraulic cylinder 13, when sensor detects, when the first hydraulic cylinder 13 reaches rated pressure to tested supporting leg 19, sensor is to pcs signal, and supporting leg 19 quits work.
The present invention not part of detailed description is known technology.
