Description

Technical Field

[0001] This utility model relates to the field of permeability testing technology, and mainly to a support mechanism for the plate removal of a permeability testing instrument. Background Technology

[0002] The impermeability of concrete (test block) refers to the ability of the materials used in a structure to resist the penetration of water or other liquid (light oil, heavy oil) media under pressure. It is an important indicator for evaluating the quality and durability of concrete, and it is also a mandatory inspection indicator for the strict quality control of concrete by various engineering quality supervision stations.

[0003] To improve the efficiency of test block testing, a number of permeability testing instruments have emerged on the consumer market. These instruments can perform multiple permeability tests simultaneously without interference and offer convenient sample block handling. The instrument includes a frame with multiple support plates inside. Each support plate is equipped with multiple permeability testing components for testing the sample blocks. Adjacent support plates are locked and unlocked via a self-locking device (the sliding plate moves horizontally relative to the support plate via the movement of a cylinder piston, thus locking or unlocking the locking pins). A synchronous lifting drive device separates the upper support plate from the lower support plate or lifts it synchronously. This mechanism features a simple structure, convenient transportation, easy maintenance, and high safety, significantly improving work efficiency.

[0004] The inventors of this application discovered at least the following problems during the implementation of the aforementioned antipermeability device:

[0005] The aforementioned permeability tester typically has a long drawing plate, so a support plate is installed at the end furthest from the cylinder. The other end of the drawing plate rests on the support plate. After prolonged use, the middle part of the long drawing plate may sink or bend, which will affect the use of the drawing plate and prevent the self-locking device from locking and unlocking, thus affecting the use of the entire machine. Utility Model Content

[0007] To achieve the above objectives, this utility model employs the following technical solution:

[0008] A support mechanism for a permeability tester's pull plate includes a frame with multiple support plates inside. Several sets of permeability testing devices are arranged between adjacent support plates. Adjacent support plates are connected by a self-locking device. The self-locking device includes a driving device, a pin, and a pull plate. The pin is disposed in the support plate, and the pull plate is disposed at the bottom of the support plate and connected to the output shaft of the driving device. The pin cooperates with the pull plate on the next support plate. A guide support is provided on the pin, and the pull plate is located on the guide support.

[0009] Furthermore, based on the above solution, the guide support is a plate-shaped structure, and a sliding groove is provided on the guide support, allowing the pull plate to move on the sliding groove.

[0010] Furthermore, based on the above solution, the guide support is provided with an installation groove, which is open at one end and sealed at the other end.

[0011] Furthermore, based on the above solution, steps are provided on both sides of the pin, and the guide support is inserted into the pin through the opening end of the mounting groove and is located on the steps.

[0028] Please refer to the following for details. Figure 1-5 A support mechanism for a permeability tester plate 6 includes a frame 1, with two sets of symmetrical columns 13 in the frame 1. Multiple support plates 2 are installed inside the frame 1, and the multiple support plates 2 are sequentially fitted onto the columns 13. Several sets of permeability test devices 3 are arranged between adjacent support plates 2. A synchronous lifting drive device 4 is installed at the bottom of the frame 1. The synchronous lifting drive device 4 is connected to the support plate 2 located on the first layer through a screw 14. The columns 13, screw 14 and synchronous lifting drive device 4 (synchronous belt structure) are prior art, so they will not be described in detail in this application.

[0029] Furthermore, adjacent support plates 2 are connected by a self-locking device, which includes a drive device 4, a pin 5, and a drawer plate 6. The pin 5 is disposed in the support plate 2, and the drawer plate 6 is disposed at the bottom of the support plate 2 and connected to the output shaft of the drive device 4. The pin 5 cooperates with the drawer plate 6 on the next support plate 2. The pin 5 is provided with a guide support 7, and the drawer plate 6 is located on the guide support 7. Under the action of the drive device 4, the drawer plate 6 can be pushed to make horizontal reciprocating motion relative to the support plate 2, thereby achieving the purpose of driving the lock groove to lock or release the pin 5.

[0030] Specifically, the upper end of the pin 5 is provided with a receiving cavity and the lower end is provided with a plug. Openings are provided on both sides of the receiving cavity. The plug of the upper pin 5 can be inserted into the receiving cavity of the lower pin 5 and exposed through the opening. The draw plate 6 is provided with a locking groove. The draw plate 6 is driven by the driving device 4 to move horizontally back and forth on the guide support 7 relative to the support plate 2, thereby achieving the purpose of driving the locking groove to lock or release the plug.

[0031] In this embodiment, the drive device 4 is preferably a cylinder. Of course, the drive device 4 can also be an electric push rod or a hydraulic cylinder.

[0032] Furthermore, the guide support 7 is a plate-shaped structure, and a groove 8 is provided on the guide support 7. The pull plate 6 is located in the groove 8 and can move on the groove 8.

[0033] Furthermore, the guide support 7 is provided with an installation groove 9, which is open at one end and closed at the other end, so that the guide support 7 can be inserted into the pin 5.

[0034] Furthermore, steps 10 are provided on both sides of the pin 5, and the guide support 7 is inserted into the pin 5 through the opening end of the mounting groove 9 and is located on the steps 10.

[0035] In this embodiment, in order to ensure the stability of the guide support 7, it can be welded to the step 10.

[0036] Furthermore, a mounting plate 11 is provided at the bottom of the support plate 2, and a drive device 4 is provided on the mounting plate 11. A linkage plate 12 is provided on the output shaft of the drive device 4, and drawer plates 6 are connected to both sides of the linkage plate 12. When the output shaft of the drive device 4 is extended or retracted through the linkage plate 12, it can drive the drawer plates 6 on both sides to move synchronously.

[0037] Furthermore, the width of the slide 8 is greater than the width of the draw plate 6, which facilitates the movement of the draw plate 6.

[0038] Furthermore, the guide support 7 is spaced out on the pins 5, that is, there is a guide support 7 on every other pin 5, so that the supporting force on the drawer plate 6 is more uniform.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
