Description

A steel-plastic geogrid testing fixture Technical Field

[0001] This utility model relates to the field of testing technology, specifically a steel-plastic geogrid testing fixture. Background Technology

[0002] Steel-plastic geogrid, also known as steel-plastic composite geogrid, is a geosynthetic material. It is made of high-strength steel wire (or other fibers) that have undergone special treatment, combined with polyethylene (PE) or polypropylene (PP) and other additives, and extruded to form a composite high-strength tensile strip with a rough embossed surface, forming a high-strength reinforced geotextile strip.

[0003] Before use, steel-plastic geogrids need to undergo a pull-out test to check their performance. However, in the existing technology, the two ends of the steel-plastic geogrid cannot be clamped and moved smoothly during the testing process, resulting in inaccurate monitoring data.

[0004] Therefore, a steel-plastic geogrid testing fixture was designed based on the above technical issues. Summary of the Invention

[0005] To address the problem that existing technologies cannot stably clamp and move both ends of a steel-plastic geogrid during testing, this invention proposes a testing fixture for steel-plastic geogrids.

[0006] The technical solution adopted by this utility model to solve its technical problem is a steel-plastic geogrid testing fixture, including a fixture platform. Two testing components are symmetrically arranged on the fixture platform. The testing components include a clamping component and a stabilizing component located at the bottom of the clamping component. The clamping component includes a base plate and a clamping mechanism located on the base plate. A connecting member is provided at the bottom of the base plate and is connected to the testing machine. The stabilizing component includes a slide table located at the bottom of the base plate, and a slider that slides in accordance with the slide table is provided at the bottom of the base plate.

[0007] Preferably, the clamping mechanism includes a back plate and a clamping plate disposed on the base plate, and a telescopic cylinder is provided above the clamping plate. The telescopic cylinder is connected to the back plate and drives the clamping plate to move up and down.

[0008] Working principle: The steel-plastic geogrid is clamped by a clamping mechanism. Specifically, the steel-plastic geogrid is placed on the base plate and the clamping plate is moved downward by the telescopic cylinder, thus clamping the steel-plastic geogrid. After clamping, the connector is connected to the testing machine for testing. During the testing process, because a sliding table with a matching slider is provided at the bottom of the base plate, the sliding is more stable while maintaining clamping during the test.

[0009] Preferably, the telescopic cylinder comprises three sets, which are respectively arranged on the two sides and the middle of the clamping plate, so that the clamping force can be more balanced.

[0010] Preferably, a centering component is provided between the two test components. The centering component includes a center plate on the fixture platform, a rotating plate on the center plate, the rotating plate being a rectangular plate, the rotating plate and the center plate being connected by a pivot shaft, and centering tie rods on both sides of the rotating plate. The two tie rods are respectively connected to the middle position of the inner side of the two base plates. The two base plates are connected by the centering component, which makes the force more uniform during the test and the test results more accurate.

[0011] Preferably, the slide table includes two sets of slide grooves, which are respectively arranged on both sides of the base plate, and two sliders are corresponding to each slide groove, making it more stable.

[0012] Preferably, the connector includes a connecting block disposed at the bottom of the base plate, the connecting block being connected to a connecting rod, the connecting rod extending to the outside of the fixture platform, and the connecting rod being provided with a connecting buckle for connection to the testing machine.

[0013] Preferably, the connecting rod is cylindrical, and a support frame is fitted in the middle of the connecting rod to prevent the test results from being affected by the weight of the connecting rod itself when the connecting rod is long.

[0014] The advantages of this utility model are:

[0015] 1. During the testing process, the present invention enables the smooth clamping and movement of both ends of the steel-plastic geogrid through the setting of the sliding table and slider, thereby increasing the accuracy of the monitoring data. At the same time, the connection with the testing machine through the connector increases the flexibility of use of this application, and it can be used for multiple machines.

[0016] 2. The present invention provides a centering component between the two test components. The centering component includes a center plate on a fixture platform, a rotating plate on the center plate, the rotating plate being a rectangular plate, the rotating plate and the center plate being connected by a pivot shaft, and centering tie rods on both sides of the rotating plate. The two tie rods are respectively connected to the middle position of the inner side of the two base plates. The two base plates are connected by the centering component, which makes the force more uniform during the test and the test results more accurate.

[0017] 3. The connecting rod of this utility model is cylindrical, and a support frame is sleeved in the middle part of the connecting rod to prevent the test results from being affected by the weight of the connecting rod itself when the connecting rod is long. Attached Figure Description
