Description

Technical Field

[0001] This utility model relates to the field of pressure bearing capacity testing technology, specifically a pressure bearing capacity testing device for woven bags used in construction. Background Technology

[0002] In construction projects, woven bags are commonly used for packaging and transporting various building materials, such as cement, sand, gravel, and tile adhesive. Their pressure-bearing capacity directly affects the safety and stability of these building materials during storage, handling, and use.

[0003] Existing methods for testing the compressive strength of woven bags are simple to operate, involving continuously adding objects into the bag until it ruptures. This is inefficient, time-consuming, and labor-intensive, and cannot accurately simulate the complex stress state that woven bags experience under actual working conditions, resulting in significant discrepancies between the test results and the actual situation. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a device for testing the compressive strength of woven bags used in construction, which has the advantages of high accuracy and solves the problems mentioned in the background technology.

[0005] To achieve the aforementioned high accuracy, this utility model provides the following technical solution: a pressure-bearing capacity testing device for woven bags used in construction, comprising a base plate and a tensile testing mechanism, wherein support frames are installed on both sides of the upper end of the base plate, and a lifting plate is installed on the upper end of the tensile testing mechanism;

[0006] A clamping seat is provided in the middle of the inner side wall of the support frame. A first sliding groove is provided at the front of the upper end of the clamping seat. A double-headed motor is installed in the middle of the clamping seat. Both ends of the double-headed motor are equipped with forward and reverse lead screws through couplings. Lead screw slides are driven on the forward and reverse lead screws. The upper ends of the lead screw slides pass through the first sliding groove and are equipped with fixing blocks. An electric hydraulic cylinder is installed in the middle of the fixing blocks. A pressure plate is installed at the rear end of the electric hydraulic cylinders. A fixing seat is installed at the rear of the upper end of the clamping seat. An L-shaped groove is provided in the fixing seat.

[0007] As a further improvement of this utility model: a groove is provided on the upper part of the front wall of the fixing seat, and an anti-slip pad is provided on the inner wall of the groove. The anti-slip pad increases the friction between the woven bag and the groove, preventing the woven bag from slipping during tensile operations, improving stability, and ensuring the accuracy of tensile data.

[0008] As a further embodiment of this utility model: a drive motor is installed on the upper end of the right support frame, and a ball screw is installed on the lower end of the drive motor through a coupling. A right slider is installed on the ball screw. A second slide groove is provided in the middle of the right side wall of the right support frame. The right end of the slider passes through the second slide groove and is equipped with a lifting plate. The lower end of the lifting plate is connected to the tensile testing mechanism. When the drive motor is started, the drive motor drives the ball screw to rotate through the coupling, which drives the lifting plate to move upward. The tensile testing mechanism drives the woven bag to move upward to perform tensile strength testing.

[0009] As a further improvement of this utility model: a left slider is installed at the left end of the lifting plate, and a limiting post passes through the middle of the left slider. The limiting post limits the left slider, thereby improving the stability of the lifting plate.

[0010] As a further improvement of this utility model: a control panel is installed in the middle of the left side wall of the support frame. The control panel is electrically connected to the tensile testing mechanism, and the numerical value is displayed on the control panel, so as to show the maximum bearing capacity.

[0011] As a further improvement of this utility model, mounting plates are installed on the lower part of both sides of the base plate, and the device is fixed by the mounting plates, which improves stability.

[0012] As a further improvement of this utility model, two support plates are provided on the lower part of the inner sidewall of the two support frames, and objects are stored on the two support plates.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In this invention, a dual-head motor is started, which drives the forward and reverse lead screws to rotate via a coupling. This causes the two lead screw slides to move, adjusting the positions of the two pressure plates. An electric hydraulic cylinder is then started, causing the pressure plates to press the woven bag tightly. A drive motor is then started, which drives the ball screw to rotate via a coupling, causing the lifting plate to move upwards. A tensile testing mechanism then moves the woven bag upwards to perform tensile strength testing. This method is highly efficient, time-saving, labor-saving, highly accurate, and has minimal deviation. Attached Figure Description
