[0022] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Reference Figure 1-4 A device for testing the crack resistance of a ring-shaped concrete pole includes a base plate 1. One end of the base plate 1 is provided with a plurality of support frames 2. The plurality of support frames 2 are arranged in a straight line and are used to support and place a ring-shaped concrete pole 13. The bottoms of the plurality of support frames 2 are each equipped with a power wheel 3, which is used to drive the ring-shaped concrete pole 13 to rotate. The tops of the plurality of support frames 2 are each provided with a horizontal cross bar 4. A cross beam 5 is detachably fixed between every two cross bars 4. The cross beam 5 is provided with a waist-shaped hole 6. The waist-shaped hole 6 is matched with a plurality of detection mechanisms. The detection mechanisms are used to detect the concrete strength of the ring-shaped concrete pole 13.

[0025] As a technical optimization solution of the present invention, two rotating seats 7 are rotatably provided at the bottom of the support frame 2, and the two ends of the power wheel 3 are detachably fixedly connected to the two rotating seats 7, so that the power wheel 3 can be detached and replaced.

[0026] As a technical optimization solution of the present invention, a motor 8 is fixed on the upper side of the base plate 1. A power shaft 9 is coaxially fixed to the motor 8. The power shaft 9 can be detachably fixedly connected to the rotating base 7. A connecting rod 10 can be detachably fixed between two opposing rotating bases 7. Under the action of the connecting rods 10, the motor 8 is started, and the motor 8 can drive the coaxially aligned power wheels 3 to rotate precisely.

[0027] As a technical optimization solution of the present invention, a disc 11 is coaxially fixed to the power shaft 9 . The disc 11 is used to abut against the edge of the annular concrete pole 13 to limit the annular concrete pole 13 .

[0028] As a technical optimization solution of the present invention, the support frame 2 is provided with an arc-shaped frame, the power wheel 3 is arranged at the bottom of the arc-shaped frame, and both ends of the arc-shaped frame are detachable and rotatable and are provided with side wheels 12. Several arc-shaped frames are used to support and place annular concrete poles 13, that is, several arc-shaped frames can be matched with the annular concrete poles 13, and the annular concrete poles 13 can be restricted to be placed in several arc-shaped frames, and the corresponding power wheels 3 and side wheels 12 can enclose the annular concrete poles 13, which have the effect of supporting and abutting against the annular concrete poles 13.

[0029] For the above examples, those skilled in the art should know that when implementing the above technical solution, the power wheel 3 and the side wheel 12 can be set with a variety of radius specifications, so as to meet the support and abutment restrictions of the annular concrete poles 13 with a variety of radius specifications.

[0030] As a technical optimization solution of the present invention, the support frame 2 is symmetrically fixed with two vertically arranged straight rods 14. One end of the cross bar 4 corresponding to the upper part of the support frame 2 is rotatably connected to one of the straight rods 14, and the other end is detachably fixedly connected to another straight rod 14. The cross bar 4 can be rotated to a vertical state, leaving a gap between the two straight rods 14, which facilitates the placement of the annular concrete pole 13 on the support frame 2. At the same time, the cross bar 4 can be rotated to a horizontal state, and one end of it is fixed to a straight rod 14 to achieve a lateral support effect.

[0031] For the above example, those skilled in the art should know that when implementing the above technical solution, the straight pole 14 can be set to a retractable setting to facilitate the adjustment of various heights, provide sufficient space for the placement of the annular concrete pole 13, and meet the placement of annular concrete poles 13 with various radius specifications.

[0032] As a technical optimization solution of the present invention, the detection mechanism includes a cylindrical frame 15, a rebound hammer 16 is slidably installed inside the cylindrical frame 15, a cylinder 17 is vertically fixed on the top of the cylindrical frame 15, the telescopic end of the cylinder 17 is fixedly connected to the bottom of the rebound hammer 16, a circular block 18 is fixed to the bottom of the cylindrical frame 15, the impact rod of the rebound hammer 16 passes through the circular block 18, the circular block 18 is inserted into and slidably matched with the waist-shaped hole 6, and one end of the circular block 18 is threadedly connected to a rotating block 19 for fastening the cylindrical frame 15 to the beam 5.

[0033] For the above example, those skilled in the art should know that when implementing the above technical solution, the basic principle of the rebound tester 16 is to use a spring to drive a heavy hammer, and the heavy hammer hits the impact rod in vertical contact with the concrete surface with constant kinetic energy, causing the local concrete to deform and absorb part of the energy, and the other part of the energy is converted into the rebound kinetic energy of the heavy hammer. When the rebound kinetic energy is completely converted into potential energy, the heavy hammer rebounds to the maximum distance, and the instrument displays the maximum rebound distance of the heavy hammer in the name of the rebound value (the ratio of the maximum rebound distance to the initial length of the spring), thereby achieving the effect of detecting the strength of the concrete.

[0034] For the above example, those skilled in the art should know that when implementing the above technical solution, the device is not limited to setting up a rebound hammer 16 for quality inspection, and ultrasonic equipment can also be set to perform strength inspection on the annular concrete pole 13.

[0035] In the present invention, the working principle of the device is as follows:

[0036] The completed annular concrete pole 13 is hoisted by an existing crane and placed on a plurality of support frames 2, i.e., a plurality of support frames 2 arranged in a straight line. The plurality of support frames 2 are pre-installed with motors 8 and a plurality of connecting rods 10. The plurality of support frames 2 provide stable support for the annular concrete pole 13. The crossbars 4 on the plurality of support frames 2 are then rotated to a horizontal state, and one end of the crossbar 4 is fixed to the corresponding straight rod 14 to achieve a lateral support effect. After completing the above operation, a crossbeam 5 is installed and fixed between every two crossbars 4. Then, according to the needs, the required number of detection mechanisms are installed on the waist-shaped hole 6 of the beam 5, and the detection operation can be carried out, that is, the cylinders 17 of several detection mechanisms are started, and the cylinders 17 push the corresponding rebound hammers 16 downwards, and the rebound hammers 16 slide along the cylindrical frame 15. The impact rod of the rebound hammer 16 finally passes through the circular ring block 18 and is squeezed into contact with the surface of the annular concrete pole 13. The impact rod is compressed and contracted, and then the cylinder 17 drives the rebound hammer 16 to reset, and the impact rod is reset, that is, the strength test of the surface of the annular concrete pole 13 is achieved. During the test, the setting of several detection mechanisms can realize the detection of multiple points, which is convenient for the comparison of data later and effectively improves the work efficiency. At the same time, after completing a test, the motor 8 can be started, and the motor 8 drives several power wheels 3 to rotate accurately, thereby driving the annular concrete pole 13 to rotate accurately and rotate the set angle. After that, the strength test can be carried out again. Through multiple rotation operations, the annular concrete pole 13 can be tested in a circumferential manner, achieving a convenient and comprehensive detection effect.

[0037] When multiple support frames 2 are provided, multiple connecting rods 10 or multiple crossbeams 5 can connect the multiple support frames 2, further achieving a stable connection of the multiple support frames 2, that is, forming the multiple support frames 2 into a whole. At the same time, the required number of support frames 2 and corresponding crossbeams 5 can be provided according to the length of the annular concrete pole 13, effectively meeting the support placement and subsequent testing requirements of annular concrete poles 13 of various lengths.

[0038] When installing the detection mechanism, insert the circular ring block 18 corresponding to the cylindrical frame 15 into the waist-shaped hole 6, then slide it to the set position, and then align the circular ring block 18 from the bottom of the beam 5 and rotate and screw it into the rotating block 19 to fasten the cylindrical frame 15 to the beam 5, thereby completing the installation of the detection mechanism.

[0039] When the motor 8 is started, it first drives the power shaft 9 to rotate, and the power shaft 9 drives the corresponding rotating seat 7 to rotate, and then drives the corresponding power wheel 3 to rotate, thereby driving the corresponding connecting rod 10 to rotate in turn, and other coaxial corresponding power wheels 3 to rotate, and finally realizes the rotation adjustment of the annular concrete pole 13.

[0040] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
