Description

Technical Field

[0001] The invention belongs to the technical field of underground continuous wall construction devices, and specifically discloses an adjustable energy storage trimming square hammer. Background Art

[0002] In recent years, with the expansion of cities, more and more urban subways have been built. Underground continuous walls are an important protective structure for subway stations and are widely used. At present, the construction method of first drilling holes and then trimming and grooving is adopted in hard rock areas in China.

[0003] The hole drilling method is generally the same as the bridge pile foundation drilling method, which includes bored pile drilling, rotary drilling and other methods, all of which require mud wall protection.

[0004] After the hole is formed, trimming and grooving require a square trimming hammer. Traditional fixed-shape trimming hammers have the following disadvantages:

[0005] 1. The square hammer has a fixed shape and can only be used to modify continuous walls of fixed width. Even if all four sides have crushing teeth, it can only be used to modify continuous walls of two widths, which has poor adaptability.

[0006] 2. When hammering down and trimming in the retaining mud of the continuous wall, the machine can only rely on the free fall acceleration in the mud, but the mud resistance is large, the speed is slow when hammering the rock mass, the hammering force is small, and the efficiency is low. The disadvantage of low efficiency is particularly obvious in hard rock;

[0007] 3. A greater hammering force can only be obtained by increasing the weight of the hammer body. The increase in the weight of the hammer body is bound to increase costs and make transportation difficult. The power of the hoist for lifting the square hammer must also be increased accordingly, resulting in high energy consumption, which is not conducive to energy conservation and emission reduction.

The end of the transmission spiral piece sliding plate 4.16.1 is hinged with the mounting hole, and the clamping plate 4.16.3 is clamped on the limiting protrusion. The transmission spiral piece sliding plate 4.16.1 and the transmission spiral piece transmission plate 4.16.2 are in contact with the transmission screw rod sliding surface 4.6.1 and the transmission screw rod transmission surface 4.6.2 respectively; the transmission spiral piece spring piece 4.17 is located on the outer side of the transmission spiral piece 4.16, with the first end fixed in the mounting hole and the second end abutting against the outer side of the transmission spiral piece sliding plate 4.16.1.

[0040] like Figure 7 , Figure 8 , Fig.10 and Fig.12As shown in the figure, taking the bottom edge of the inclined blade 4.1 tilted to the left and the serration direction of the transmission screw rod 4.6 as an example, when the square hammer is lifted, the square hammer exerts an upward force on the mud, and the mud exerts a downward reaction force on the inclined blade 4.1, so that the inclined blade 4.1 rotates clockwise, driving the inertial flywheel 4.2 and the transmission screw rod 4.6 to rotate clockwise, the serrations of the transmission screw rod 4.6 are engaged with the connection angle of the transmission spiral piece sliding plate 4.16.1 and the transmission spiral piece transmission plate 4.16.2, the transmission spiral piece transmission plate 4.16.2 exerts force on the transmission spiral piece transmission plate 4.16.2, driving the transmission inner ring 4.15 to rotate clockwise, and the clockwise rotating transmission inner ring 4.15 tightens the spiral energy storage spring piece 4.14, so that the spiral energy storage spring piece 4.14 is in a tensioned state. When the square hammer is lifted up and strikes down, the inclined blade 4.1 loses the reaction force of the mud and gradually stops rotating. When the inclined blade 4.1 stops rotating, the serrations of the transmission screw rod 4.6 no longer have a binding force on the spiral energy storage spring piece 4.14, and the spiral energy storage spring piece 4.14 in a tensioned state will begin to rebound, driving the transmission inner ring 4.15 to rotate counterclockwise. The connection angle of the transmission spiral piece sliding plate 4.16.1 and the transmission spiral piece transmission plate 4.16.2 applies a counterclockwise thrust to the serrations of the transmission screw rod 4.6, so that the transmission screw rod 4.6 drives the inertia flywheel 4.2 and the inclined blade 4.1 to rotate counterclockwise, cut the mud, and apply a downward force to the hammer body, thereby accelerating the square hammer. After the spiral energy storage spring 4.14 completely releases its elastic force, the inclined blade 4.1 and the inertia flywheel 4.2 will continue to rotate counterclockwise under the action of inertia, continuously exerting downward force on the other hammer body and continuously accelerating. At this time, the spiral rod sliding surface 4.6.1 of the counterclockwise rotating transmission spiral rod 4.6 presses the transmission spiral piece 4.16 into the transmission inner ring 4.15, so that the meshing between the transmission spiral rod 4.6 and the transmission inner ring 4.15 is released, and the transmission spiral rod 4.6 idles, thereby avoiding the reverse tension of the spiral energy storage spring 4.14.

[0041] Furthermore, the inclined blade 4.1 is a downwardly concave arc-shaped blade so as to obtain a greater reaction force.
