Description

Technical Field

[0001] This utility model relates to the field of geogrid tensile testing technology, specifically a geogrid tensile testing device. Background Technology

[0002] A patent document with publication number CN219224346U discloses an on-site pull-out testing device for existing geogrids. The device includes reinforcing bars that are threaded through a mandrel and locked to the upper end of the mandrel by a tool anchor. The mandrel is mounted on a support stool with a perforation in the middle. A reinforcing bar located at the lower end of the mandrel passes through the support stool, and its lower end is connected to a clamp. A filler layer is provided above the retaining wall components. The lower end of the geogrid is embedded in the retaining wall components and the filler layer, while the upper end of the geogrid extends beyond the filler layer. The support stool is positioned above the filler layer, and the clamp holds the geogrid. A displacement gauge is connected to the clamp via a displacement lead-out rod. This invention allows for on-site pull-out testing of existing geogrids after construction, obtaining accurate pull-out force and deformation data. It features convenient operation, a safe and reliable structure, and accurate test results.

[0003] During the test, the geogrid may generate debris due to its own material properties or impurities on its surface when it is under tensile stress. At the same time, dust, particles and other debris can easily accumulate on the test platform. Existing devices usually do not have dedicated cleaning components. If these debris accumulates for a long time, it may affect the installation accuracy of the specimen in subsequent tests and may also cause additional wear on the surface of the geogrid during the tensile process.

[0004] Therefore, this utility model proposes a geogrid tensile testing device to solve the above problems. Utility Model Content

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some embodiments of this utility model, not all embodiments, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. The technical solutions in the embodiments of this utility model will be clearly and completely described below.

[0020] Example 1: Please refer to Figures 1 to 2 A geogrid tensile testing device includes a base 1, a tensile device 2, and a wooden geogrid 3. The tensile device 2 is slidably engaged on the base 1, and the wooden geogrid 3 is disposed on the tensile device 2. The tensile device 2 is driven by a driving device. The base 1 is provided with a securing component 4, a sliding component 5, and a cleaning component 6. The securing component 4 is disposed on the tensile device 2, the sliding component 5 is disposed on one side end of the base 1, and the cleaning component 6 is disposed at the bottom end of the base 1.

[0021] The securing protrusions 401 in the securing component 4 are evenly distributed at the top of the tensioning device 2. A wood grid 3 is snapped onto the securing protrusion 401, and a securing seat 402 is fixedly provided on the side of the securing protrusion 401.

[0022] The top of the fastening protrusion 401 in the fastening component 402 is fitted and fixedly engaged with the fastening base 402 by a snap-fit ​​protrusion 403. The snap-fit ​​protrusion 403 is provided with a snap-fit ​​groove 404 and a snap-fit ​​hole 405. The snap-fit ​​groove 404 is snapped and fixedly engaged with the fastening base 402, and the snap-fit ​​hole 405 is snapped and fixedly engaged with the fastening protrusion 401.

[0023] In use, place the wood grid 3 on the tensioning device 2, aligning the edge of the wood grid 3 with the fixed protrusion 401. Then, align the locking hole 405 of the locking protrusion 403 with the fixed protrusion 401 and the locking groove 404 with the fixed seat 402 and press until the locking protrusion 403 is fully locked with the fixed seat 402 and the fixed protrusion 401. At this time, the wood grid 3 is firmly clamped. Start the drive device to drive the tensioning device 2 to slide on the base 1, and the tensile test can be carried out to prevent the wood grid 3 from slipping during the tension.

[0024] Example 2: Based on Example 1, please refer to... Figures 2 to 3 The lead screw 501 in the sliding assembly 5 is fixedly installed on one end of the base 1, and a sleeve ring 502 is slidably sleeved on the lead screw 501.

[0025] A fixing rod 503 is fixedly installed on the sleeve ring 502 in the sliding component 5, and a cleaning brush 504 is evenly arranged on the top end of the fixing rod 503.

[0026] During use, before or after the test, rotate the lead screw 501. The connecting ring 502 will slide along the lead screw 501 and drive the fixed rod 503 to move. The cleaning brush 504 at the top of the fixed rod 503 moves with it to clean the bottom of the wood grid 3, sweeping the dust, fine particles and other debris attached to the wood grid 3 to one side, ensuring that the test area is clean and providing convenience for subsequent test preparation or cleaning.

[0027] Example 3: Based on Example 2, please refer to... Figures 3 to 4 The cleaning cotton 601 in the cleaning component 6 is fixedly installed at the bottom end of the fixed rod 503. The cleaning cotton 601 is in close contact with the cleaning bucket 602, which is installed on the base 1.

[0028] In use, when the fixed rod 503 moves with the sleeve ring 502, the cleaning cotton 601 at its bottom moves synchronously. The cleaning cotton 601 contacts the surface of the cleaning bucket 602, further gathering the debris swept down by the cleaning brush 504 and moving it to the outside of the cleaning bucket 602. The cleaning cotton 601 pushes out the debris in the cleaning bucket 602, completing the collection of debris and achieving efficient cleaning of debris.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
