Description

Technical Field

[0001] The utility model belongs to the field of vibratory hammers, and in particular relates to a vibratory hammer with adjustable clamping distance and angle. Background Art

[0002] Vibratory hammers are used to generate powerful excitation force to drive objects into the ground. They utilize an electric motor to drive paired eccentrics in opposite rotations, canceling out the lateral centrifugal forces while adding to the vertical centrifugal forces. The high-speed rotation of the eccentrics causes the gearbox to vibrate vertically, achieving the goal of driving piles. These hammers are widely used in foundation engineering.

[0003] However, the current vibratory hammer still has some shortcomings. The existing vibratory hammer has not yet fully considered the clamping structure. During the use of the vibratory hammer, if the vibratory hammer has not fully considered the clamping structure, the clamping position is single, which may cause great damage to the clamped workpiece, and the clamping may not be stable enough, which may cause loosening during the subsequent operation of the vibratory hammer, making it inconvenient for the staff to use the vibratory hammer.

[0028] like Figures 1 to 6 As shown, the vibratory hammer with adjustable clamping distance and angle of the utility model includes a hanger 1, a fixing plate 6 and a clamping assembly 9. An electric push rod 2 is provided below the hanger 1, and an adjusting assembly 3 is provided above the electric push rod 2. A universal joint 4 is provided at the bottom of the electric push rod 2, and a rotating assembly 5 is provided at the top of the universal joint 4.

[0029] Among them, the adjustment component 3 includes a fixed block 301, an arc track 302, a sliding card 303 and a rolling wheel 304, and the number of the fixed blocks 301 is three, the three fixed blocks 301 are welded to the bottom of the hanger 1, and the arc track 302 is welded between the fixed blocks 301, and the outer side of the arc track 302 is engaged and slidably connected with the sliding card 303, and the sliding card 303 is fixedly connected to the top of the electric push rod 2, and the inner surface of the arc track 302 is provided with a tooth surface, and the arc track 302 is engaged and rotatably connected with the rolling wheel 304 through the tooth surface, and the rolling wheel 304 is engaged and rotatably connected to the inner side of the sliding card 303.

[0030] In some embodiments, the rotating assembly 5 includes a fixed frame 501, a drive motor 502, a rotating member 503, a connecting rod 504, a bevel gear 505 and a rotation limiter 506, and the fixed frame 501 is fixedly connected to the bottom center of the electric push rod 2, and a drive motor 502 is provided on one side of the fixed frame 501, and the output shaft of the drive motor 502 is fixedly connected to the rotating member 503 through a coupling, one end of the rotating member 503 is rotatably connected to the inner wall of the fixed frame 501, and the end of the rotating member 503 is fixedly connected to the inner wall of the fixed frame 501. A connecting rod 504 is provided below the rotating member 503, and a bevel gear 505 is welded to the middle section of the rotating member 503 and the top of the connecting rod 504. The rotating member 503 and the connecting rod 504 are engaged and rotatably connected via the bevel gear 505. The bottom end of the connecting rod 504 is welded to the top center of the universal shaft 4, and a rotation limiter 506 is provided on the outside of the connecting rod 504. The rotation limiter 506 is welded to the bottom of the fixed frame 501, and the rotation limiter 506 is engaged and rotatably connected to the top of the universal shaft 4.

[0031] The specific operation is as follows: the staff uses the relative engagement and rotation between the rolling wheel 304 and the tooth surface opened on the inner surface of the curved track 302 to make the sliding card 303 engage and slide on the outer side of the curved track 302, thereby making the electric push rod 2 fixedly connected to the bottom of the sliding card 303 move its position. In addition, the staff can use the rotating assembly 5 to rotate the universal shaft 4 below, and use the driving motor 502 to drive the rotating member 503 to rotate on the inner side of the fixed frame 501, and under the meshing rotation of the bevel gear 505, the connecting rod 504 follows the rotation of the rotating member 503. Because the bottom end of the connecting rod 504 is welded to the top center of the universal shaft 4, as the connecting rod 504 rotates, the universal shaft 4 below it also rotates, and the rotation limiter 506 set on the outer side of the connecting rod 504 engages and rotates with the top of the universal shaft 4, thereby making the connection between the structures tight, which is convenient for the staff to use the vibrating hammer.

[0032] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 and Figure 6 As shown, the fixed plate 6 is fixedly connected to the bottom of the universal joint 4, and a limiting block 7 is fixedly connected to one side of the bottom of the fixed plate 6, and a blocking block 8 is fixedly connected to the other side of the bottom of the fixed plate 6, and a clamping assembly 9 is set below the fixed plate 6.

[0033] The clamping assembly 9 includes a small motor 901, a limiting screw rod 902, a sprocket 903, a transmission chain 904, a locking slider 905 and a clamping block 906. The small motor 901 is arranged on one side of the fixed plate 6, and the output shaft of the small motor 901 is fixedly connected to the limiting screw rod 902 through a coupling, and there are two limiting screw rods 902. The outer walls of the ends of the two limiting screw rods 902 are welded with sprockets 903, and the outer sides of the sprockets 903 are rotatably connected to the transmission chain 904. The limiting screw rod 902 is rotatably connected to the inside of the fixed plate 6, and the outer sides of the limiting screw rod 902 are rotatably connected to the locking slider 905, and the bottom of the locking slider 905 is welded with a clamping block 906, and the clamping block 906 is in contact with the side of the blocking block 8.

[0034] After the staff adjusts the position and angle of the clamping assembly 9, the clamping assembly 9 is used to clamp the workpiece, and the small motor 901 is used to drive the limiting screw rod 902 to rotate. Under the transmission action of the sprocket 903 and the transmission chain 904, the two limiting screw rods 902 rotate synchronously inside the fixed plate 6, so that the engaging slider 905 rotatingly connected to the outer side of the limiting screw rod 902 gradually engages and slides with the fixed plate 6, thereby driving the clamping block 906 welded on the bottom of the engaging slider 905 to move. As the clamping block 906 moves, the workpiece is gradually firmly limited between the clamping block 906 and the limiting block 7. The structure is simple, which is convenient for the staff to use the vibration hammer.

[0035] according to Figures 1-6 In the structure shown in FIG, during the use of the vibratory hammer, first, the staff utilizes the relative engagement and rotation between the rolling wheel 304 and the tooth surface provided on the inner surface of the arc track 302, so that the sliding clamp 303 engages and slides on the outer side of the arc track 302, thereby causing the electric push rod 2 fixedly connected to the bottom of the sliding clamp 303 to move in position;

[0036] The staff can use the rotating assembly 5 to rotate the universal shaft 4 below, and use the driving motor 502 to drive the rotating part 503 to rotate inside the fixed frame 501. Under the meshing rotation of the bevel gear 505, the connecting rod 504 is rotated along with the rotating part 503. Because the bottom end of the connecting rod 504 is welded to the top center of the universal shaft 4, as the connecting rod 504 rotates, the universal shaft 4 below it also rotates. The rotation limiter 506 provided on the outside of the connecting rod 504 is engaged and rotatably connected with the top of the universal shaft 4, thereby ensuring a tight connection between the structures.

[0037] After the staff adjusts the position and angle of the clamping assembly 9, the clamping assembly 9 is used to clamp the workpiece, and the small motor 901 is used to drive the limiting screw rod 902 to rotate. Under the transmission action of the sprocket 903 and the transmission chain 904, the two limiting screw rods 902 rotate synchronously inside the fixed plate 6, so that the engaging slider 905 rotatably connected to the outer side of the limiting screw rod 902 gradually engages and slides with the fixed plate 6, thereby driving the clamping block 906 welded on the bottom of the engaging slider 905 to move. As the clamping block 906 moves, the workpiece is gradually firmly limited between the clamping block 906 and the limiting block 7, which is convenient for the staff to operate.

[0038] The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for specific applications.
