DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, purposes and effects realized by the utility model easy to understand, the utility model is further described in combination with specific implementation manners.

[0022] Please refer to Figures 1 to 3 The utility model provides a technical scheme: wood pile nondestructive testing equipment based on ultrasonic waves, including walking base plate 1 and four sound wave mechanisms 2, the bottom of walking base plate 1 is provided with walking wheel, the structure of sound wave mechanism 2 adopts the structure in the patent literature mentioned in background art, and up and down sliding base 3 is arranged on walking base plate 1, and four sound wave mechanisms 2 are arranged in the circumferential ring around up and down sliding base 3.

[0023] In the technical solution, the upper and lower sliding seats 3 are provided with short connecting arms 4 forming a cross on the outer side walls of the upper and lower sliding seats 3, that is, there are four short connecting arms 4, and the four short connecting arms 4 are located on the side lines of the cross. The sound wave mechanism 2 is fixedly provided with a base 21, which supports other components of the sound wave mechanism 2. One side of the base 21 is fixedly connected with a connecting beam 5 having one end rotatably connected with the short connecting arm 4. The rotating axis of the connecting beam 5 and the short connecting arm 4 is vertically arranged. When the connecting beam 5 rotates, the sound wave mechanism 2 connected with the connecting beam 5 can be switched between two positions above and outside the walking base 1. When the sound wave mechanism 2 is located beside the walking base 1, the non-destructive ultrasonic detection can be performed. When the sound wave mechanism 2 is located above the walking base 1, the walking base 1 can stably walk, and the space occupied by the whole device is greatly reduced. When the upper and lower sliding seats 3 move up and down, the four sound wave mechanisms 2 move up and down, and thus the drill pins on the sound wave mechanisms 2 move up and down.

[0024] The top of the walking base 1 is fixedly connected with two guide columns 11. The upper and lower sliding seats 3 are provided with guide sleeves 31 close to the two sides and in sliding fit with the guide columns 11. The upper end surface of the walking base 1 is fixedly connected with a driving motor 7. The output shaft of the driving motor 7 is fixedly connected with a transmission screw 71 in screw fit with the upper and lower sliding seats 3. When the transmission screw 71 rotates, the driving force is used to control the up and down movement of the upper and lower sliding seats 3. The driving motor 7 provides the driving force for the rotation of the transmission screw 71.

[0025] In the technical solution, the control mechanism 6 is arranged on the front and rear sides of the upper and lower sliding seats 3. The control mechanism 6 has the function of synchronously and oppositely rotating the two connecting beams 5 adjacent to the control mechanism 6. This arrangement does not need manual control of the swinging of the connecting beams 5.

[0026] Specifically, the control mechanism 6 includes telescopic rods 61 and connecting rods 62. One end of the telescopic rod 61 is fixedly connected with one side of the upper and lower sliding seats 3, and the action ends of the telescopic rod 61 are hingedly connected with one side of the adjacent connecting beams 5 through the two connecting rods 62. The telescopic rod 61 can be an electric push rod structure. When the telescopic rod 61 acts, the two connecting beams 5 on the two sides of the telescopic rod 61 are pushed to swing oppositely through the two connecting rods 62.

[0027] Further, the opposite sides of the two connecting beams 5 adjacent to the telescopic rod 61 are fixedly connected with limit stakes 9. This arrangement makes the free ends of the limit stakes 9 on the two connecting beams 5 abut when the two connecting beams 5 swing oppositely to the limit position, thereby improving the stability of the two connecting beams 5 after the opposite movement to the limit position. The free end of the limit stake 9 is bonded with a buffer rubber pad 91. The buffer rubber pad 91 can reduce the impact force when the two connecting beams 5 oppositely move to the limit position, and can effectively avoid the impact on the sound wave mechanism 2.

[0028] In addition, the upper end surface of the walking base plate 1 is provided with two protective covers 8 close to the front and rear ends, which are in sliding fit with the walking base plate 1 and have openings on the side facing the control mechanism 6. When the sound wave mechanism 2 is located directly above the walking base plate 1, the protective cover 8 is controlled to slide to a certain distance in the direction of the up-down sliding seat 3, at which time the two sound wave mechanisms 2 are located in the protective cover 8, thereby having the advantage of surrounding protection for the sound wave mechanism 2.

[0029] Among them, the two sides of the protective cover 8 are welded with sliding blocks 81, and the upper end surface of the walking base plate 1 is provided with sliding grooves 12 in sliding fit with the sliding blocks 81. In use, the walking base plate 1 is connected with a screw rod, which is in penetrating and screwing fit with the protective cover 8, so that the movement of the protective cover 8 can be controlled by controlling the rotation of the screw rod.

[0030] Working principle: When nondestructive testing, the four connecting beams 5 form a cross state, at which time the sound wave mechanism 2 is located outside the walking base plate 1, the driving motor 7 is started to control the rotation of the transmission screw 71 to control the up-down movement of the up-down sliding seat 3, thereby driving the overall up-down movement of the four sound wave mechanisms 2. When the detection is completed and the device needs to be shifted, the telescopic rod 61 is controlled to be elongated, and the moving end of the telescopic rod 61 drives the opposite movement of the adjacent two connecting beams 5 through the two connecting rods 62, and the corresponding sound wave mechanism 2 is translated to the upper side of the walking base plate 1, then the protective cover 8 is controlled to slide in the direction of the up-down sliding seat 3, and the protective cover 8 covers the outside of the sound wave mechanism 2, thereby the device can be moved smoothly.

[0031] In addition, it should be understood that although the present specification is described in terms of embodiments, not every embodiment contains only one independent technical solution, and the description of the specification is only for the sake of clarity, and those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be combined appropriately to form other embodiments that those skilled in the art can understand.
