Technical Field

[0001] The utility model relates to the technical field of concrete pole production, in particular to a multi-point strength detection device for a concrete pole. Background Art

[0002] At present, after the production of each batch of concrete pole products is completed, its quality needs to be tested, which is mainly to check the flatness and strength of the pole surface. When testing the strength of concrete poles, the hydraulic press is mainly used to drive the extrusion block to extrude the pole surface to realize the pressure detection process, so that the strength of the pole surface can be monitored to determine whether it is qualified. However, the existing strength detection device only detects a certain position of the pole, and rarely detects multiple positions on the pole surface. For example, patent CN210198688U-a stability detection device for reinforced concrete pole production only performs strength detection on a certain position point of the pole, and it is difficult to fully detect the strength of the pole because there may be contingency. One of the positions on the pole surface is qualified, but the positions in other areas may have weak strength. This causes errors in the detection process of the pole strength.

[0016] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0017] like Figure 1 As shown, a multi-point strength detection device for a concrete pole comprises a base 1 arranged on the bottom surface, the top of the base 1 is fixedly connected to the bottom of a lifting platform 3 through a hydraulic cylinder 2, the top surface of the lifting platform 3 is provided with an arc groove 4, the inner side of the arc groove 4 is hinged with a plurality of fixed pulleys 5 that cooperate with the surface of the pole, the top surface of the lifting platform 3 is slidably matched with the bottom of a reaction frame 6, the top of the reaction frame 6 is connected to an extrusion block 8 through a connecting rod 7, a plurality of support rods 9 that cooperate with the surface of the pole are vertically fixed on the surface of the base 1, and the top of the support rod 9 passes through the surface of the arc groove 4 and slidably cooperates with it.

[0018] Preferably, the top surface of the support rod 9 is a curved surface structure that matches the surface of the electric pole. After such a design, the contact between the electric pole and the support rod 9 becomes stable and is not easily displaced.

[0019] Preferably, a slide rail 10 is provided on the top surface of the lifting platform 3, and a slide groove 11 is provided on the bottom side of the reaction frame 6, and the slide rail 10 and the slide groove 11 are slidably matched. Through the cooperation between the slide rail 10 and the slide groove 11, the reaction frame 6 can slide smoothly on the top surface of the lifting platform 3.

[0020] Preferably, the reaction frame 6 is a U-shaped frame structure, and its bottom is also fixedly connected to the top of the U-shaped reinforcement frame 6.1, and the U-shaped reinforcement frame 6.1 is slidably matched with the outer side of the lifting platform 3. During the detection process, in the vertical direction, there is a tendency for the bottom side of the reaction frame 6 and the top surface of the lifting platform 3 to separate from each other, and the binding force between the slide groove 11 and the slide rail 10 alone may cause the problem of being torn or pulled apart, so the bottom of the reaction frame 6 is slidably connected to the lifting platform 3 through the U-shaped reinforcement frame 6.1, which can further enhance the binding force between the reaction frame 6 and the lifting platform 3 in the vertical direction, and at the same time does not affect the horizontal sliding process between the reaction frame 6 and the lifting platform 3.

[0021] Preferably, the fixed pulley 5 is hingedly arranged on the inner side of the arc surface groove 4 through a wheel frame 5.1.

[0022] Preferably, the base 1 is a rectangular plate-shaped structure, and each of its four corners is provided with a hydraulic cylinder 2. After such a design, the four hydraulic cylinders 2 work together to make the applied force more balanced.

[0023] The working principle of this embodiment is as follows:

[0024] like Figure 2 and 3 As shown, the concrete pole to be inspected is placed on the fixed pulley 5 in the arc groove 4 through the hanger (at this time, the lifting platform 3 is at a higher position, and the fixed pulley 5 protrudes from the top of the support rod 9). Due to the rotation characteristics of the fixed pulley 5, the friction of the pole rotation can be reduced, and it can be directly rotated manually, and then the reaction frame 6 is pushed to slide along the lifting platform 3 to the area to be inspected. At this time, the hydraulic cylinder 2 contracts, thereby pulling the lifting platform 3 downward. When the top of the support rod 9 protrudes from the fixed pulley 5, the pole contacts the top of the support rod 9 and stays at this position (as shown in FIG. Figure 4 As shown in FIG. 1 , during the downward movement of the lifting platform 3, the reaction frame 6 and the extrusion block 8 on the top thereof move downward together. When the lifting platform 3 continues to move downward, when the extrusion block 8 contacts the surface of the pole (as shown in FIG. 1 ), the reaction frame 6 and the extrusion block 8 on the top thereof move downward together. Figure 5As shown in the figure, under the pulling force of the hydraulic cylinder 2 on the lifting platform, the support rod 9 and the reaction frame 6, the extrusion block 8 generates pressure on the surface of the pole, and the power of the hydraulic cylinder 2 is adjusted to enable it to generate different pulling forces. Different pulling forces of the hydraulic cylinder 2 correspond to different pressures generated by the extrusion block 8 on the surface of the pole, thereby performing a pressure test on the pole, and testing the lowest pressure that can cause damage to the surface of the pole, so that the strength of the pole in this area can be judged; after completing the pressure detection process of this site, the hydraulic cylinder 2 is extended to push the lifting platform 3 upward, and when the fixed pulley 5 protrudes from the top of the support rod 9, the pole can be manually rotated so that the extrusion block 8 is aligned with other sites of the pole, and then the hydraulic cylinder 2 is contracted, and the above pressure detection process is repeated to obtain the strength of another site in the area. Strength; after completing the pressure detection process of the site in the area, the hydraulic cylinder 2 extends and pushes the lifting platform 3 to move upward. When the fixed pulley 5 protrudes from the top of the support rod 9, the reaction frame 6 is pushed to slide along the lifting platform 3 to another area to be detected. The hydraulic cylinder 2 contracts and repeats the above pressure detection process to obtain the strength of a point in another detection area. Similarly, after the hydraulic cylinder 2 extends, it pushes the lifting platform 3 to move upward. When the fixed pulley 5 protrudes from the top of the support rod 9, the pole can be manually rotated so that the extrusion block 8 is aligned with other sites of the pole. Then the hydraulic cylinder 2 contracts and repeats the above pressure detection process to obtain the strength of another point in the area; after completing the detection of multiple sites in all areas to be detected, the average value of the strength of each site can be obtained, and this average value is the strength value of the entire pole.
