DETAILED DESCRIPTION

[0021] Example 1: Reference Figure 1 , including a right clamping ear 1, a top clamping plate 2, a front clamping arm 3, and a rear clamping arm 4. The top clamping plate 2 is a gantry-shaped structure, and a support shaft 5 is arranged between the two ends of the top clamping plate 2. The front clamping arm 3 and the rear clamping arm 4 are symmetrically distributed front and back to form a left clamping ear 6, and a connecting plate 7 is connected between the top end of the front clamping arm 3 and the top end of the rear clamping arm 4, and a limiting plate 8 is connected between the lower end of the front clamping arm 3 and the lower end of the rear clamping arm 4. The right clamping ear 1, the front clamping arm 3, and the rear clamping arm 4 are respectively movably mounted on the support shaft 5, and the right clamping ear 1 is located between the front clamping arm 3 and the rear clamping arm 4. The top clamping plate 2 is connected to the drop hammer height frame through a steel strand, and the top of the right clamping ear 1 and the connecting plate 7 are respectively passed through a steel strand lifting device, and the lower part of the right clamping ear 1 and the lower part of the left clamping ear 6 cooperate with each other to be hooked on the top hook of the heavy hammer, and the upper weight of the right clamping ear 1 and the left clamping ear 6 is greater than the weight of the lower part thereof.

[0022] Mounting through holes 9 are respectively provided on both sides of the top of the top clamping plate 2, a first connecting through hole 10 is provided on the connecting plate 7, and a second connecting through hole 11 is provided on the top of the right clamping ear 1. The mounting through hole 9, the first connecting through hole 10 and the second connecting through hole 11 are respectively used to connect the steel strands.

[0023] When in use, the top clamp plate 2 is connected to the drop hammer height frame (not shown) of the guide hammer frame through the installation through hole 9 and the steel strand, and the right clamp ear 1 and the left clamp ear 6 are respectively connected to the lifting device (not shown) through the steel strand, and the steel strand of the lifting device falls to place the left clamp ear 6 and the right clamp ear 1 to the horizontal position of the weight hammer top hook. Since the upper weight of the right clamp ear 1 and the left clamp ear 6 is greater than the weight of the lower part, the steel strand connecting the lifting device is in a relaxed state, and the upper part of the left clamp ear 6 and the upper part of the right clamp ear 1 move away from each other and open under the action of gravity, so that the lower part of the left clamp ear 6 and the lower part of the right clamp ear 1 move away from each other and open. After the left clamp ear 6 and the right clamp ear 1 are placed in the horizontal position of the weight hammer top hook, the steel strand of the left clamp ear 6 and the right clamp ear 1 is lifted. At this time, due to the lifting and tightening of the steel strand, the lower part of the left clamp ear 6 and the lower part of the right clamp ear 1 are closed together under the action of the angle and force. After the upper and lower parts of the left and right clamping ears 6 are clamped and closed, the bottom end of the right clamping ear 1 is clamped into the bottom end of the front clamping arm 3 and the bottom end of the rear clamping arm 4, and the bottom end of the right clamping ear 1 is against the limit plate 8, so that the bottom end of the right clamping ear 1 is clamped into the bottom end of the front clamping arm 3 and the rear clamping arm 4, which can improve the reliability of the closure of the right and left clamping ears 1 and 6. After rising to a certain height of the hammer drop, the steel strand connected to the top clamping plate 2 can realize arbitrary control of the hammer drop height. After fixing the hammer drop height, the left and right clamping ears 6 and 1 are dropped. At this time, the steel strand connecting the left and right clamping ears 6 and 1 is in a relaxed state, and the angle between the left and right clamping ears 6 and 1 becomes larger. The heavy hammer automatically disengages from the heavy hammer top hook under the action of gravity, providing effective hammering. The whole process is semi-automated, which greatly improves the detection efficiency and reduces the risk of the detection process.

[0024] Example 2: Reference Figures 2 to 6 The difference between this embodiment and the first embodiment is that the inner sides of the upper parts of the right clamping ear 1 and the left clamping ear 6 are respectively inwardly concave arc shapes, and a locking structure 12 is provided in the top clamping plate 2. The locking structure 12 is respectively connected to the upper part of the left clamping ear 6 and the upper part of the right clamping ear 1, and a decoupling spring 13 is connected between the upper part of the left clamping ear 6 and the upper part of the right clamping ear 1, and the decoupling spring 13 is located above the locking structure 12.

[0025] The locking structure 12 includes a mounting plate 14, a movable plate 15, a left connecting rod 16, a right connecting rod 17, a locking rod 18, and a locking groove 19. The mounting plate 14 is fixed in the top clamping plate 2. A vertically distributed slide groove 20 is provided on the mounting plate 14. The movable plate 15 is movably arranged on the slide groove 20. The left connecting rod 16 and the right connecting rod 17 are symmetrically distributed with each other, and one end of the left connecting rod 16 is hinged to the movable plate 15, and the other end of the left connecting rod 16 is hinged to the left clamping ear 6. One end of the right connecting rod 17 is hinged to the movable plate 15, and the other end of the right connecting rod 17 is hinged to the right clamping ear 1. The locking rod 18 is movably arranged on the movable plate 15, and the locking groove 19 is fixed on the mounting plate 14, and the locking groove 19 is located on the movement trajectory of the locking rod 18.

[0026] A mounting seat 21 is provided on the mounting plate 14 , and the locking rod 18 is connected to the mounting seat 21 via a telescopic rod 22 , and a locking spring 23 is sleeved on the telescopic rod 22 .

[0027] Both ends of the chute 20 are closed.

[0028] The notch of the locking groove 19 is in a slope shape.

[0029] When the left clamping ear 6 and the right clamping ear 1 are closed, the left connecting rod 16 and the right connecting rod 17 interact with each other to push the movable plate 15 up along the sliding groove 20. When the locking rod 18 rises with the movable plate 15 to the position of the locking groove 19, the outer end of the locking rod 18 slides from the sloped notch into the locking groove 19 (such as Figure 5 The locking spring 23 is pressed against the locking bar 18 and the locking bar 18 is pressed against the locking bar 19, thereby releasing the locking bar 18 and releasing the locking bar 18.
