[0033] The present invention will be further described in detail below in conjunction with specific implementation methods to better reflect the advantages of the present invention.

[0034] In the embodiment of the utility model, the motor and hydraulic press necessary for the operation of the high-pressure jet grouting equipment are also included to enable the drill rod 2 to move up and down and to achieve the conventional setting of cement filling. The structure of the utility model is only an improved structure in the high-pressure jet grouting equipment, and the driving mode is not limited;

[0035] Example 1: Figure 1-Figure 3 As shown, a low-cost vibration-reducing high-pressure rotary jet pile equipment comprises a machine body 1, a drill rod 2 and a drill bit 3. The machine body 1 is composed of a pile frame 11 and a base 12. A retractable support member 14 is provided on the base 12. The base 12 is hollow inside and is provided with a connecting member for linking the drill bit 3 and the support member 14. The drill bit 3 is provided with a toggle member that triggers the connecting member when moving up and down to make the support member 14 retractable.

[0036] In one implementation, the drill rod 2 is movably connected to the upper part of the pile frame 11, the drill bit 3 is connected to the lower end of the drill rod 2, and a nozzle 21 is provided on one side of the drill rod 2 close to the drill bit 3;

[0037] Optionally, the above-mentioned movable connection is one of the movable connections in the prior art, such as a threaded connection;

[0038] Optionally, the connection between the drill bit 3 and the lower end of the drill rod 2 may be a fixed connection;

[0039] In one implementation, Figure 3-Figure 7 As shown, the above-mentioned connecting member includes a connecting plate 121 arranged inside the base 12, and the connecting plate 121 is slidably connected to the side wall inside the base 12 up and down, and the support member 14 includes a supporting tube 142 fixed to the bottom surface of the base 12, and a moving rod 141 passing through the supporting tube 142 and connected to the connecting plate 121; the upper and lower parts of the side wall inside the base 12 are both provided with grooves 122, and the groove 122 is provided with a block 123 for locking the connecting plate 121, and the block 123 is connected to the bottom surface of the groove 122 through a first spring.

[0040] The above-mentioned definition of the support member 14 can utilize the up and down movement of the drill bit 3 to push the connecting plate 121, so that the moving rod 141 and the supporting tube 142 can be extended during the operation of the high-pressure rotary jet pile, avoiding the use of an electric telescopic rod, thereby reducing the equipment manufacturing or installation cost. When the operation is completed, the upward movement of the drill bit 3 can push the connecting plate to drive the moving rod 141 to move upward, so that the operation of the drill bit 3 is associated with the extension and contraction of the support member, thereby increasing the convenience of use.

[0041] Furthermore, the toggle member is an end edge 31 disposed on the upper portion of the drill bit 3 for pushing the connecting plate 121 to move, and a torsion spring shaft rotatably connected to the drill bit 3 is disposed on the end edge 31 .

[0042] For example, the connecting plate 121 can be replaced by a connecting strip or other component capable of achieving a connecting function, and the specific shape is not limited, for example Figure 5 The connecting plate 121 shown;

[0043] In one implementation, the connecting plate 121 is slidably connected to the side wall inside the base 12 by means of a sliding groove and a sliding rail;

[0044] The above-mentioned slide groove and slide rail are only a specific way to realize the up and down sliding of the connecting plate 121 and the side wall inside the base 12. The connection plate 121 can also be connected to the top surface of the base 12 by a spring.

[0045] In one implementation, the bottom of the base 12 is provided with a crawler system 13, and the crawler system 13 is commercially available using existing technology; the crawler system 13 is only one implementation, and any device that enables the device to move can be used, such as tires;

[0046] The working method of the above equipment is:

[0047] Open the device (specifically, the driving device of the opening device, such as a hydraulic press that enables the drill rod 2 to move up and down and the existing equipment for cement filling), move the drill rod 2 downward, and during the downward movement of the drill rod 2, the end edge 31 of the drill bit 3 pushes the connecting plate 121 to move downward, and when the connecting plate 121 moves down to the block 123 located at the bottom, the block 123 clamps the connecting plate 121, and at this time, the moving rod 141 extends out of the support tube 142 for support, and during the continued downward movement of the drill bit 3, the end edge 31, under the action of the torsion spring, flips the angle to allow the drill bit 3 to continue to move downward; similarly, during the upward movement of the drill rod 2, the end edge 31 pushes the connecting plate 121 to move upward, and the upper block 123 clamps the connecting plate 121, and the end edge 31, under the action of the torsion spring, flips the angle to allow the drill bit 3 to continue to move upward; the telescopic support 14 is associated with the drill rod 2.

[0048] Embodiment 2: This embodiment is basically the same as Embodiment 1, except that;

[0049] In one implementation, a box body 15 for the drill bit 3 to pass through is fixed on the base 12, and the box body 15 is connected to the inside of the base 12;

[0050] The setting of the above-mentioned box body can facilitate the isolation and placement of the drill bit, avoiding the possibility of cement in the drill bit contaminating the surrounding area due to exposure to the environment; therefore, as long as the box body plays a barrier role, it can be realized, and there is no limitation on the specific shape of the box body, such as a rectangle.

[0051] Embodiment 3: This embodiment is basically the same as Embodiment 1, except that;

[0052] For example, Figure 8 As shown, a stabilizing rod 143 is provided on the moving rod 141, the upper end of the stabilizing rod 143 is rotatably connected to the moving rod 141, the lower part of the stabilizing rod 143 is connected to the moving rod 141 through a second spring, and the width of the stabilizing rod 143 is equal to four fifths of the distance between the moving rod 141 and the inner wall of the support tube 142.

[0053] Exemplarily, the width of the stabilizing rod 143 only needs to be smaller than the distance between the moving rod 141 and the inner wall of the supporting tube 142, for example, three fifths;

[0054] In another implementation, the second spring may be replaced by other elastic members, such as an elastic airbag;

[0055] In another implementation, the second spring may be replaced by a connecting rope, one end of which is connected to the inner wall of the support tube 142, and the other end of which is connected to the middle of the stabilizing rod 143;

[0056] The working method of this embodiment is the same as that of the first embodiment. When the moving rod 141 extends out of the support tube 142, the stabilizing rod is stretched out under the action of the second spring, thereby increasing the stability of the moving rod 141 and enhancing the vibration reduction effect on the machine body 1.

[0057] Embodiment 4: This embodiment is basically the same as Embodiment 1, except that;

[0058] Optionally, a rubber pad is provided on the box body 15 through which the drill bit 3 passes; the rubber pad is commercially available;

[0059] The rubber pad is provided to address the problem that the area of ​​the box body 15 through which the drill bit 3 passes is prone to vibration, thereby further enhancing the vibration reduction effect of the equipment and thereby increasing the service life of the equipment.

[0060] Embodiment 5: This embodiment is basically the same as Embodiment 1, except that;

[0061] Optionally, a rubber cushion is provided at the connection between the base 12 and the support member 14; the rubber cushion is commercially available;

[0062] The rubber cushion is set to address the problem of vibration at the connection between the base 12 and the support 14, so as to further enhance the vibration reduction effect of the equipment and thus increase the service life of the equipment.

[0063] The above only makes specific arrangements for two areas that are prone to collision and vibration. Rubber pads may also be arranged at other places of the device to improve the vibration reduction effect of the device, which will not be elaborated in this embodiment.
