Specific embodiment
Below with reference to examples and drawings, the present invention is described in further detail, but embodiments of the present invention are not
It is limited to this.
Embodiment 1:
In the present embodiment, a kind of push action test device of subway electric hook, including pedestal 1, setting are on pedestal 1 and for mentioning
For the driving structure of driving force, with the drive mechanism of driving structure transmission connection and setting on pedestal 1 and for being slidably installed
The guide frame of subway electric hook 16 is provided with the subway electric hook connection for connecting with subway electric hook 16 on the drive mechanism
Structure 13 is provided with pressure sensor 12 between the drive mechanism and subway electric hook connection structure 13.The ground ferroelectricity
Hook connects structure 13 is detachably connected with subway electric hook 16, for example, by using being threadedly coupled, snapping connection, can guarantee to test with this
When, the stability between subway electric hook connection structure 13 and subway electric hook 16, additionally it is possible to quickly be dismantled.In the present embodiment,
The common knowledge and customary means for being detachably connected as those skilled in the art, those skilled in the art are according to we
The content that case is recorded can be realized said effect, not repeat herein the specific structure and working principle that are detachably connected.
Other components are installed and supported as installation foundation using pedestal 1, and are easy to implement whole shifting
It is dynamic.Subway electric hook 16 is slidably mounted on guide frame, subway electric hook connection structure 13 is connect with subway electric hook 16, utilizes biography
The power that driving structure exports is transferred to subway electric hook connection structure 13 by dynamic structure, and drives subway electric hook 16 being oriented to this
It is slided in structure, to simulate the movement for pushing subway electric hook 16.
As shown in figure 3, several docking needles 162 are provided on the subway electric hook 16, when test, by pairs of subway
Electric hook 16 is mounted on two push action test devices, makes the docking needle 162 on two pairs of subway electric hooks 16 is opposite to set
It sets, is utilized respectively two push action test devices and two pairs of subway electric hooks 16 is pushed to move toward one another, to simulate subway
The movement that electric hook 16 docks.The stress of docking needle 162 can be detected during docking using pressure sensor 12, is changed
The direction of driving structure output power makes two drive mechanisms pull two subway electric hooks 16 backwards to moving respectively, utilizes pressure
The detection docking needle 162 of sensor 12 suffered pulling force when being detached from, the product quality of subway electric hook 16 is judged according to the data detected.
This programme has the advantages that structure is simple, easy to use, relative to transmission means, can quickly be realized, and
And the influence by place, environment is smaller, does not need the devices such as big, the practical hitch at high cost of volume and is tested, energy
Enough costs for reducing experiment test.
In the present embodiment, to the customary means of the field technical staff that bases on practicality of pressure sensor 12, art technology
The content that personnel record according to this programme selects suitable pressure sensor 12 to can be realized said effect, does not pass herein to pressure
Specific structure, model and the working principle of sensor 12 are defined and repeat.
Embodiment 2:
As shown in fig. 6, on the basis of the above embodiments, in the present embodiment, the guide frame includes two parallel to each other
Guide rail 17 and the guiderail base 18 at 17 both ends of guide rail is set, the subway electric hook 16 is slidably connected with guide rail 17.
Guide rail 17 is supported using guiderail base 18, two guiderail bases 18 is utilized respectively and supports a guide rail 17,
The stability and rigidity that can be improved guide rail 17 avoid in mobile overall structure or experimentation, and guide rail 17 bends
It deforms and reduces own form precision or measuring accuracy.Using guiderail base 18 can also the movement of ferroelectricity hook 16 over the ground play limit
The effect of position avoids subway electric hook 16 during moving towards because of displacement to control the displacement of subway electric hook 16
Amount control is bad and causes to dock the damage of needle 162.Subway electric hook 16 is limited using two guide rails 17 parallel to each other with guide rail
17 be the rotational freedom of axis, so as to enhance stability and position precision when the installation of subway electric hook 16, movement, from
