[0051] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0052] Example 1

[0053] like Figure 1 , Figure 2 As shown, this embodiment discloses a vertical jacking device, which includes: a screw machine 1, a pipe jacking machine 2, a first position monitoring component 3, a second position monitoring component 4, a controller 5, a first driving mechanism 6 and a jack 7;

[0054] The internal machine system 21 of the pipe jacking machine 2 and the outer shell 22 of the pipe jacking machine 2 are fixedly connected by a detachable connection method; specifically, the detachable connection method between the internal machine system 21 of the pipe jacking machine 2 and the outer shell 22 of the pipe jacking machine 2 includes: pin connection or bolt connection.

[0055] The cylinder wall of the jack 7 is fixedly connected to the housing 22 of the pipe jacking machine 2;

[0056] The piston rod of the jack 7 is fixedly connected to the internal machine system 21 of the pipe jacking machine 2;

[0057] Specifically, the jack 7 applies pressure to the inner machine of the pipe jacking machine 2 to ensure that the inner machine system 21 of the pipe jacking machine 2 and the outer shell 22 of the pipe jacking machine 2 are closely connected.

[0058] The controller 5 is electrically connected to the first position monitoring component 3, the second position monitoring component 4 and the first driving mechanism 6 respectively;

[0059] The screw machine 1 is used to transport the soil upward to the soil box in the cavity of the pipe jacking machine 2; specifically, when the pipe is pushed downward, the cutter disc of the inner machine stirs the soil to loosen it, and then the screw machine 1 is used to transport the soil upward to the soil box, and then the soil box is lifted by a crane to transport the soil out.

[0060] The first position monitoring component 3 is used to collect first position information and send the first position information to the controller 5; specifically, the first position information represents the position information of the pipe jacking machine when it is jacking downward;

[0061] The second position monitoring component 4 is used to collect second position information and send the second position information to the controller 5; specifically, the second position information represents the position information of the internal machine system of the pipe jacking machine moving upward;

[0062] The controller 5 is used to determine whether the first position information reaches a first preset threshold value, and if so, generates a first trigger instruction; the first trigger instruction is used to trigger the first driving mechanism 6 to separate the internal machine system 21 of the pipe jacking machine 2 from the outer shell 22 of the pipe jacking machine 2;

[0063] The first trigger instruction is also used to trigger the contraction of the jack 7 to drive the internal machine system 21 of the pipe jacking machine 2 and the cutter head assembly 23 of the pipe jacking machine 2 to move upward;

[0064] The first trigger instruction is also used to trigger the screw machine 1 to stop working;

[0065] Specifically, when the pipe jacking machine 2 is pushed downward, the first position monitoring component 3 collects the position information of the pipe jacking machine 2 and sends the position information to the controller 5. When the controller 5 determines that the position information reaches a preset threshold, it indicates that the downward pushing of the pipe jacking is completed, and then generates a trigger instruction to trigger the first driving mechanism 6 to separate the internal machine system 21 of the pipe jacking machine 2 and the outer shell 22 of the pipe jacking machine 2, and the trigger jack 7 contracts to drive the internal machine system 21 of the pipe jacking machine 2 and the cutter disc assembly 23 of the pipe jacking machine 2 to move upward. In addition, the trigger instruction also triggers the screw machine 1 to stop working.

[0066] The controller 5 is further configured to receive and determine whether the second position information reaches a second preset threshold, and if so, generate a second trigger instruction;

[0067] The second trigger instruction is also used to trigger the jack 7 to stop contracting.

[0068] Specifically, when the internal machine system 21 of the pipe jacking machine 2 and the cutter disc assembly 23 of the pipe jacking machine 2 move upward, the second position monitoring assembly 4 collects the position information of the internal machine system 21 of the pipe jacking machine 2 moving upward, and sends the position information to the controller 5. When the controller 5 determines that the position information reaches a preset threshold, it generates a trigger instruction to trigger the jack 7 to stop contracting, so that the internal machine system 21 of the pipe jacking machine 2 stops moving upward.

[0069] This example discloses a vertical jacking device, which is provided with a pipe jacking machine 2, a screw machine 1, a first position monitoring component 3, a second position monitoring component 4, a controller 5, a first driving mechanism 6 and a jack 7. Through the cooperation of various components, the vertical jacking operation of the pipe jacking is realized.

[0070] like Figure 3 , Figure 4 , Figure 5 As shown, in an operative manner, the cutter disc assembly 23 of the pipe jacking machine 2 includes: a first cutter disc 231, a plurality of second cutter discs 232 and a second driving mechanism 233;

[0071] The first cutter disc and each of the second cutter discs are fixedly mounted on the bottom end surface of the internal machine system;

[0072] The surface of each second cutter disc is arranged above the surface of the first cutter disc; the distance between the surface of the second cutter disc and the surface of the first cutter disc is within a preset range; specifically, the distance between the surface of the second cutter disc and the surface of the first cutter disc can be 5cm-15cm, and can generally be set to 10cm.

[0073] The second driving mechanism 233 is electrically connected to the controller 5;

[0074] The second blade disc comprises a spoke shaft; in particular, the second blade disc may comprise one spoke shaft.

[0075] The first trigger instruction is also used to trigger the second drive mechanism 233 to rotate each of the second blade discs 232 around the center of the second blade disc 232 so as to point the spoke axis to the center of the blade disc assembly 23. Specifically, the first trigger instruction is used to trigger the second drive mechanism 233 to rotate each of the second blade discs 232 around the center of the second blade disc 232 so as to point the spoke axis to the center of the blade disc assembly 23 before the internal machine system is separated from the housing.

[0076] Specifically, when the pipe jacking machine 2 is pushed downward, the first position monitoring component 3 collects the position information of the pipe jacking machine 2 and sends the position information to the controller 5. When the controller 5 determines that the position information reaches a preset threshold, it indicates that the downward pushing of the pipe jacking is completed, and then generates a trigger instruction to trigger the second drive mechanism 233 to rotate each of the second cutter discs 232 around the center of the second cutter disc 232, and the spoke axes of all the second cutter discs 232 point to the center of the cutter disc assembly 23.

[0077] In this solution, by providing a first cutter disc 231, a plurality of second cutter discs 232 and a second drive mechanism 233 in the cutter disc assembly 23 of the pipe jacking machine 2, when the pipe jacking is completely pushed downward, the controller 5 generates a first trigger instruction to trigger the second drive mechanism 233 to rotate each of the second cutter discs 232 around the center of the second cutter disc 232, and the spoke axes of all the second cutter discs 232 point to the center of the cutter disc assembly 23, thereby ensuring the effect of the cutter discs cutting the soil while preventing the subsequent crane from touching the outer shell 22 of the pipe jacking machine 2 when taking out the internal machine system 21 of the pipe jacking machine 2 and the cutter disc assembly 23 of the pipe jacking machine 2 from the cavity of the pipe jacking machine 2.

[0078] In one practicable manner, the vertical jacking device further comprises a pipe segment 8;

[0079] One end of the jack 7 is fixedly connected to the pipe section 8 .

[0080] In this solution, one end of the jack 7 is fixedly connected to the pipe section 8, thereby ensuring the verticality of the jack 7, thereby ensuring that when the jack 7 is compressed, the internal machine system 21 of the pipe jacking machine 2 and the cutter head assembly 23 of the pipe jacking machine 2 move upward.

[0081] In an practicable manner, the vertical jacking device further includes a water-stopping cloth 9;

[0082] The water stop cloth 9 is arranged between the outer shell 22 of the pipe jacking machine 2 and the internal machine system 21 of the pipe jacking machine 2 .

[0083] In this solution, a water stop cloth 9 is provided between the outer shell 22 of the pipe jacking machine 2 and the internal machine system 21 of the pipe jacking machine 2, so that when the mud is injected into the front of the head of the pipe jacking machine 2, the mud is prevented from flowing into the internal space cavity of the pipe jacking machine 2. Specifically, the timing of injecting mud into the front of the head of the pipe jacking machine 2 is when the internal machine system 21 of the pipe jacking machine 2 and the cutter head assembly 23 of the pipe jacking machine 2 move upward.

[0084] like Figure 6 As shown, in one practicable manner, the vertical jacking device further includes a guide tube 10;

[0085] The conduit 10 is used for concrete pouring.

[0086] In this solution, when the internal machine system 21 of the pipe jacking machine 2 moves upward to the preset position, the guide tube 10 is installed for concrete pouring. The guide tube 10 can penetrate into the mud below from the gap of the first cutter disc 231. In order to ensure pressure balance, mud of the same nature can be injected into the guide tube 10 before lowering the guide tube 10. Pour the concrete bottom seal under the head of the pipe jacking machine 2. During pouring, the pouring amount is strictly controlled to prevent the cutter disc assembly 23 and the internal machine system 21 from sinking into the concrete. At the same time, the concrete wraps part of the outer shell 22 of the pipe jacking machine 2. After pouring, the guide tube 10 is removed and the concrete is cured. During the curing process, the cutter disc assembly 23 can be opened intermittently so that the cutter disc rotates at a lower speed, thereby preventing the concrete from bonding the cutter disc assembly 23 to the concrete bottom seal below.

[0087] like Figure 7 As shown, in one practicable manner, the vertical jacking device further includes a crane 11;

[0088] The crane 11 is used to take out the internal machine system 21 of the pipe jacking machine 2 and the cutter head assembly 23 of the pipe jacking machine 2 from the cavity of the pipe jacking machine 2 .

[0089] Specifically, after the concrete reaches the curing strength, the mud between the internal machine system 21 of the pipe jacking machine 2 and the bottom cover is drained, the jack 7 and the water-stop cloth 9 are removed, and the internal machine system 21 of the pipe jacking machine 2 and the cutter head assembly 23 of the pipe jacking machine 2 are taken out from the cavity of the pipe jacking machine 2 using the crane 11.

[0090] Example 2

[0091] like Figure 8 As shown, this embodiment discloses a vertical jacking construction method, which is implemented by using the vertical jacking device in Example 1. The construction method includes:

[0093] Step S102, the controller determines whether the first position information reaches a first preset threshold, and if so, executes step S103;

[0094] Step S103, generating a first trigger instruction;

[0095] The first trigger instruction is used to trigger the first driving mechanism to separate the internal machine system of the pipe jacking machine from the outer shell of the pipe jacking machine;

[0096] The first trigger instruction is also used to trigger the contraction of the jack to drive the internal machine system of the pipe jacking machine and the cutter head assembly of the pipe jacking machine to move upward;

[0097] The first trigger instruction is also used to trigger the screw machine to stop working;

[0098] Step S104, the second position monitoring component collects second position information and sends the second position information to the controller; the second position information represents the position information of the internal machine system of the pipe jacking machine moving upward;

[0099] Step S105, the controller determines whether the second position information reaches a second preset threshold, and if so, executes step S106;

[0100] Step S106, generating a second trigger instruction; the second trigger instruction is also used to trigger the jack 7 to stop contracting.
