The utility model comprises the following steps:

the utility model aims to provide a clamping device for a cement electric pole tensile test.

The utility model comprises the following steps: the utility model provides a cement pole clamping device for tensile test, includes the test bench be provided with a pair of anchor clamps on the test bench the outside of anchor clamps is provided with the hydro-cylinder, hydro-cylinder fixed mounting is in on the test bench install the channel steel on the piston rod of hydro-cylinder, the outer end of channel steel with the outer wall fixed connection of anchor clamps, anchor clamps are used for pressing from both sides tight experimental cement pole.

Further, the clamp is semicircular, brackets are arranged at two ends of the clamp, and the brackets are arranged on the test bed.

Further, a rubber pad is mounted on the inner surface of the clamp.

Further, reinforcing ribs are arranged on two sides of the groove-shaped steel, and the outer ends of the reinforcing ribs are fixedly connected with the clamp.

Further, a placement guide plate is mounted on the test stand.

Further, a supporting swing arm is hinged to the test bed, and a semicircular supporting clamping groove is arranged at the outer end of the supporting swing arm.

Further, a supporting roller is arranged on the lower bottom surface of the supporting swing arm.

Furthermore, a countersunk hole is formed in the test bed, and a reinforcing nail is arranged in the countersunk hole.

The utility model has the beneficial effects that: the clamp is driven by the oil cylinder to clamp the bottom of the cement electric pole, so that accuracy of data obtained by a test is ensured, test workload is reduced, and test cost investment is reduced.

Description of the drawings:

FIG. 1 is a front view of the present utility model;

FIG. 2 is a top view of the utility model;

FIG. 3 is a schematic cross-sectional view of section A-A of FIG. 1;

in the figure, 1 test bench, 2 anchor clamps, 3 hydro-cylinders, 4 groove type steel, 5 brackets, 6 strengthening rib, 7 place guide board, 8 support swing arm, 9 support draw-in groove, 10 support gyro wheel.

The specific embodiment is as follows:

for a clearer understanding of technical features, objects, and effects of the present utility model, a specific embodiment of the present utility model will be described with reference to the accompanying drawings:

please refer to fig. 1 to 3, a clamping device for cement pole tensile test, which comprises a test bench 1, wherein a pair of clamps 2 are arranged on the test bench 1, an oil cylinder 3 is arranged on the outer side of each clamp 2, the oil cylinder 3 is fixedly arranged on the test bench 1, a groove-shaped steel 4 is arranged on a piston rod of the oil cylinder 3, the outer end of the groove-shaped steel 4 is fixedly connected with the outer wall of each clamp 2, each clamp 2 is used for clamping a cement pole, each clamp 2 is in a semicircular shape, brackets 5 are arranged at two ends of each clamp 2, each bracket 5 is arranged on the test bench 1, rubber pads are arranged on the inner surfaces of the clamps 2, reinforcing ribs 6 are arranged on two sides of each groove-shaped steel 4, and the outer ends of the reinforcing ribs 6 are fixedly connected with the clamps 2.

Specifically, the cement electric pole to be subjected to tensile test is effectively clamped through the pair of clamps 2, so that the accuracy of experimental data acquisition is guaranteed, the working strength in the test process is reduced, and the test cost input is reduced.

In the in-service use, at first use fork truck to lift and place between a pair of anchor clamps 2 with cement pole for test, bracket 5 holds the pole, and semi-circular anchor clamps 2 firmly tighten it under hydro-cylinder 3's effect, and the rubber pad prevents anchor clamps 2 and pole hard contact to the protection pole surface is not destroyed in tensile test.
