Description

Technical Field

[0001] The utility model relates to the technical field of geotextile production, in particular to a stretching device for geotextile production. Background Technique

[0002] Geotextiles are divided into woven geotextiles and non-woven filament geotextiles. Geotextiles have high strength. Since plastic fibers are used, they can maintain sufficient strength and elongation in both dry and wet states, and can be corrosion-resistant for a long time in soils and waters with different pH values. When producing geotextiles, in order to ensure that geotextiles have good tensile properties, it is necessary to conduct tensile tests on geotextiles.

[0003] At present, when conducting tensile tests on geotextiles after production, it is carried out manually, which not only has low efficiency but also consumes a lot of effort. Based on this, we propose an improvement to a stretching device for geotextile production. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a stretching device for geotextile production, which can effectively solve the technical problems in the background technique that when conducting tensile tests on geotextiles manually, the efficiency is low and it consumes a lot of effort.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A stretching device for geotextile production includes a vertical frame, two clamping mechanisms and a tensiometer. The two clamping mechanisms are respectively slidably and fixedly arranged on the vertical frame. The clamping mechanism includes a mounting frame. On both side plates of the mounting frame, cylinders are fixedly connected. The output ends of the two cylinders are fixedly connected with clamping plates. On the outer wall near the upper end of the vertical frame, a mounting seat and a driving block are respectively slidably arranged. The mounting seat and the driving block are connected by a tensiometer. In the middle of the front end of the vertical frame, a toothed plate is fixedly arranged. A gear is rotatably connected in the driving block, and the gear meshes with the toothed plate.

[0007] As a further scheme of the utility model, the biting surfaces of the two clamping plates are both made of an S-shaped structure, and the biting surfaces of the two clamping plates are arranged to match each other.

[0008] As a further scheme of the utility model, auxiliary rods are slidably sleeved on both side plates of the mounting frame, and one end of each auxiliary rod is fixedly connected to the outer wall of the clamping plate.

[0009] As a further scheme of the utility model, limiting grooves are opened on both sides of the vertical frame, and limiting rods are fixedly connected between the upper and lower inner walls of the two limiting grooves. The two side feet of the driving block are respectively slidably sleeved on the outer walls of the two limiting rods.

[0010] As a further solution of the present utility model, a chute is provided on the front end face of the vertical frame. A sliding rod is fixedly connected between the upper and lower inner walls of the chute. A slider is slidably sleeved on the outer wall of the sliding rod. The mounting seat is fixedly connected to the outer wall of the slider.

[0011] As a further solution of the present utility model, the upper mounting frame is fixedly connected to the lower end face of the mounting seat, and the lower mounting frame is fixedly connected to the base of the vertical frame.

[0012] As a further solution of the present utility model, a motor is fixedly provided on the outer wall of the driving block. The output end of the motor is fixedly connected to one end of the rotating shaft fixedly sleeved with the gear.

[0013] The beneficial effects of the present utility model are as follows:

[0014] By providing a vertical frame, a clamping mechanism, a mounting seat, a tensiometer, a driving block, a gear and a toothed plate structure, the geotextile can be fixed by the clamping mechanism, and then the gear rotates on the toothed plate, thereby driving the driving block to rise, and then driving the mounting seat to rise through the tensiometer, so as to stretch the geotextile through the clamping mechanisms at the upper and lower ends for testing. Compared with manual stretching, it is more labor-saving and has higher efficiency. And since the occluding surface of the clamping plate is wavy, it can not only ensure the occluding strength, but also effectively reduce the situation of fracture at the occluding part during the detection of the geotextile, improving the detection accuracy;

[0015] Driving the driving block to rise by the rotation of the gear can make the clamping mechanism smoother when stretching the geotextile, improving the accuracy of the detection result and having practicability. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0021] To make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation manners.

[0022] As Figures 1-4 shown, a stretching device for geotextile production includes a vertical frame 1, two clamping mechanisms 2 and a tensiometer 13. The two clamping mechanisms 2 are respectively slidably and fixedly arranged on the vertical frame 1. The clamping mechanism 2 includes a mounting frame 201. Cylinders 202 are fixedly connected to both side plate bodies of the mounting frame 201. Clamping plates 203 are fixedly connected to the output ends of the two cylinders 202. A mounting seat 6 and a driving block 10 are respectively slidably arranged on the outer wall of the vertical frame 1 near the upper end. The mounting seat 6 and the driving block 10 are connected by a tensiometer 13. A toothed plate 7 is fixedly arranged in the middle of the front end of the vertical frame 1. A gear 11 is rotatably connected in the driving block 10. The gear 11 meshes with the toothed plate 7.

[0023] In this embodiment, the occluding surfaces of the two clamping plates 203 are both made of an S-shaped structure, and the occluding surfaces of the two clamping plates 203 are arranged to match each other, improving the occluding stability and at the same time reducing the probability that the occluding part of the geotextile is broken.

[0024] In this embodiment, auxiliary rods 204 are slidably sleeved on both side plate bodies of the mounting frame 201. One end of the auxiliary rod 204 is fixedly connected to the outer wall of the clamping plate 203, and the force on the clamping plate 203 is loaded through the auxiliary rod 204.

[0025] In this embodiment, limiting grooves 8 are opened on both sides of the vertical frame 1. Limiting rods 9 are fixedly connected between the upper and lower inner walls of the two limiting grooves 8. The two side feet of the driving block 10 are respectively slidably sleeved on the outer walls of the two limiting rods 9, and the lifting movement of the driving block 10 is guided and limited through the limiting rods 9.

[0026] In this embodiment, a chute 3 is opened on the front end face of the vertical frame 1. A sliding rod 4 is fixedly connected between the upper and lower inner walls of the chute 3. A slider 5 is slidably sleeved on the outer wall of the sliding rod 4. The mounting seat 6 is fixedly connected to the outer wall of the slider 5. By sliding the slider 5 on the outer wall of the sliding rod 4, the lifting movement of the mounting seat 6 can be stabilized, avoiding side pull on the tensiometer 13 and affecting the detection result.

[0027] In this embodiment, the upper mounting frame 201 is fixedly connected to the lower end face of the mounting seat 6, and the lower mounting frame 201 is fixedly connected to the base of the vertical frame 1. When the upper clamping mechanism 2 is reset, only by reversing the gear 11, the upper clamping mechanism 2 can approach the lower clamping mechanism 2 under the action of gravity.

[0028] In this embodiment, a motor 12 is fixedly arranged on the outer wall of the driving block 10. The output end of the motor 12 is fixedly connected to one end of the rotating shaft of the fixedly sleeved gear 11, and the gear 11 is driven to rotate by the motor 12.

[0029] It should be noted that the present utility model is a stretching device for geotextile production. When in use, the two ends of the geotextile are first placed between the clamping plates 203, and then the clamping plates 203 are driven by the cylinder 202 to clamp and fix the geotextile. Then, the motor 12 is started to drive the gear 11 to rotate. Since the gear 11 meshes with the toothed plate 7, the driving block 10 can drive the mounting seat 6 to rise through the tensiometer 13, and further drive the clamping mechanism 2 located at the upper end to rise, so as to perform a stretching test on the geotextile, and the reading is recorded by the tensiometer 13, which is convenient and labor-saving.
