Description

Technical Field

[0001] The utility model relates to the application field of hydraulic rods, and in particular to a hydraulic telescopic times recording structure. Background Art

[0002] The number of times the hydraulic rod is extended and retracted is the test data of the hydraulic rod fatigue test, which is usually tested 6 times per minute. In actual use, the number of times the hydraulic rod is extended and retracted is also used as a reference value for the hydraulic rod. It can be used to record the number of times the hydraulic rod itself is used, and can also indirectly record the number of production operations.

[0003] The simplest way to record the number of times is to contact a push switch during reciprocating extension and retraction. Each time the push switch is pressed, it is counted once. This technology is also very mature; but this method must reach the position of the push switch to count successfully. If the extension stroke cannot meet the demand, it cannot be counted. Therefore, if a distance switch is selected as the detection component, the distance sensor is used to sense the change to trigger the switch to change the working state, and the detection is more flexible.

[0004] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a hydraulic telescopic times recording structure.

[0011] Furthermore, the anti-slip pad is made of rubber or hard cotton with a rough surface.

[0012] Preferably, the receiver is mainly composed of a housing, a main control microcontroller chip and a chip power supply. It records the number of level changes of the distance switch and uses the rising edge as the acquisition condition of the main control microcontroller chip, that is, each rising edge count can be completed every time the distance switch changes its switch state. This is a commonly used mature electronic technology.

DETAILED DESCRIPTION

[0021] like Figure 1 to Figure 4 As shown, the utility model is a hydraulic telescopic times recording structure, including a distance switch 1, which is an existing product, usually composed of a distance sensor, a controller and a switch. When the distance sensor detects that the distance reaches a threshold, it will change the switch state. It also includes a mounting structure 2 and a detection structure 3. The detection structure 3 is arranged on the mounting structure 2, and the distance switch 1 is installed on the detection structure 3. The detection structure 3 includes a fixed structure 4, a wireless recorder 5 and a mechanical recorder 6. The fixed structure 4 is arranged on the mounting structure 2, the wireless recorder 5 is arranged on the fixed structure 4 and adopts a contactless method for counting, and the mechanical recorder 6 is arranged on the fixed structure 4 and adopts a contact method for counting.

[0022] The fixed structure 4 includes a fixed frame 7, a support rod 8, a support plate 9 and a placement frame 10. The fixed frame 7 is arranged on the mounting structure 2, the support rod 8 is arranged on the fixed frame 7, the support plate 9 is arranged on multiple groups of support rods 8, and the placement frame 10 is arranged on the support plate 9; there are two groups of placement frames 10, and multiple groups of limit grooves 11 are arranged on the placement frame 10 to facilitate the placement of items.

[0023] The wireless recorder 5 includes a fixed clip 12 and a receiver 13. The fixed clip 12 is arranged on the fixed frame 7. There are multiple groups of fixed clips 12. The distance switch 1 is engaged with the multiple groups of fixed clips 12. The receiver 13 is placed in one group of placement frames 10 and is electrically connected to the distance switch 1; the mechanical recorder 6 includes a push switch 14 and a counting display 15. The push switch 14 is installed on the fixed frame 7. The counting display 15 is placed in another group of placement frames 10 and is electrically connected to the push switch 14. When pressed once, the counting display increases by one. It is an existing product and you can directly choose a product of suitable size.

[0024] The mounting structure 2 includes mounting rings 16 and anti-skid pads 17. Two groups of mounting rings 16 are symmetrically arranged. One group of mounting rings 16 is installed on the fixing frame 7, and the other group of mounting rings 16 is installed on one group of mounting rings 16. Two groups of anti-skid pads 17 are arranged on the mounting rings 16 respectively; the anti-skid pads 17 are made of rubber or hard cotton with a rough surface to play an anti-skid role.

[0025] During specific use: place the mounting ring 16 against the outer tube of the hydraulic rod from both sides, assemble the two sets of mounting rings 16, place the anti-skid pad 17 close to the outer tube of the hydraulic rod, and install the external structure on the hydraulic rod output rod. It should be noted that the external structure must ensure that it can contact the push switch 14 and can cover the detection range of the distance switch 1. When the external structure squeezes the push switch 14 under the extension and contraction of the hydraulic rod, the counting display 15 counts up once. After the distance switch 1 detects that the distance has changed and exceeds the threshold, it will also change the switch state and send the signal to the receiver 13 for counting once.

This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
