Description

Technical Field

[0001] The present invention relates to the technical field of excavation equipment, and particularly to a full-section excavation equipment based on earthmoving machinery and hydraulic machinery. Background Art

[0002] The full-section excavation method, also known as the full-section tunneling method, is a construction method in which the roadway (tunnel) is excavated in accordance with the designed excavation section and excavated in place at one time. In the process of excavation, a combined excavation equipment is required for better excavation efficiency.

[0003] The existing excavation equipment has the following problems in actual application:

[0004] 1. During the excavation of the tunnel by the existing excavation equipment, although it is possible to rely on manual spraying of water towards the excavation end face to wash away the soil layer inside the tunnel for subsequent excavation operations, it is very easy to cause incomplete spraying during manual spraying, thus having limitations.

[0005] 2. During the excavation of the tunnel by the existing excavation equipment, due to its cooperative excavation method using hydraulic machinery and earthmoving machinery, it is unable to quickly collect and preprocess the slurry generated during excavation during the excavation operation, which will affect the subsequent excavation efficiency of the tunnel.

[0006] In view of this, research and improvement are carried out on the existing structure and deficiencies to provide a full-section excavation equipment based on earthmoving machinery and hydraulic machinery. Summary of the Invention

[0007] The present invention provides a full-section excavation equipment based on earthmoving machinery and hydraulic machinery, which solves the problem that during the excavation of the tunnel by the existing excavation equipment, due to its cooperative excavation method using hydraulic machinery and earthmoving machinery, it is unable to quickly collect and preprocess the slurry generated during excavation during the excavation operation, which will affect the subsequent excavation efficiency of the tunnel.

[0008] The present invention provides the purpose and efficacy of the full-section excavation equipment based on earthmoving machinery and hydraulic machinery, specifically including: a base and a motor A. The main body of the base is a tubular structure, and a transfer box is installed at the left end of the base for transferring soil. A driver is also installed inside the base. A transmission shaft is installed on the left side of the driver, and the transmission shaft installed on the left side of the driver passes through the transfer box to the left and protrudes from the transfer box. The motor A is used to drive the roller to rotate, and a protective net is wound around the outside of the roller. The other end of the protective net is connected to the adjacent protective plate. A pump body is installed inside the base, and an extraction pipe is installed inside the pump body. The left side of the extraction pipe is communicated with the transfer box.

[0009] Further, spray holes are arranged in a circular array on the left side of the water collecting base. The spray holes opened in the water collecting base are used for spraying water. A pump water tank is installed on the right side of the driver. The pump water tank is communicated with the water collecting base through a hose, and a pump is also installed on the right side of the pump water tank.

[0010] Further, a cutter head is installed on the transmission shaft installed on the left side of the driver. The cutter head is located on the left side of the transfer box. The cutter head is of a hollow internal structure, and feed pipes are installed in a circular array inside the cutter head. The feed pipes are communicated with the transfer box.

[0011] Further, the hydraulic push rod B and the support plate together form a lifting structure. A bracket is installed on the side of the support plate far from the hydraulic push rod B through a spring, and a pressure sensor is installed on the side of the support plate close to the bracket. The pressure sensor is electrically connected to the hydraulic push rod B.

[0012] Further, the pump is used for pumping air. An air extraction pipe is installed at the top of the pump. The air extraction pipe is communicated with the transfer box. The pump and the air extraction pipe together form an extraction structure. Hydraulic push rods B are installed in a circular array on the outer peripheral surface of the driver, and a support plate is installed on the side of the hydraulic push rod B far from the driver.

[0013] Further, a protective plate is fixedly connected to the side of the bracket far from the support plate. The protective plate is of a hollow arc-shaped structure and is of a one-way opening structure. Rollers are also installed inside the protective plate, and a motor A is installed on the outside of the protective plate.

[0014] Further, the pump pumps liquid through an extraction pipe. A motor B is installed inside the base, and a separation tank is also installed inside the base. A sieve box is installed inside the separation tank. The sieve box is connected to the transmission shaft installed at the top of the motor B. The top of the extraction pipe is installed with a supply pipe for supplying sediment. A soil extraction pipe is installed on the outside of the separation tank. The soil extraction pipe is located inside the sieve box and is used for extracting soil. A drain pipe is installed on the right side of the separation tank for draining water.

[0015] Further, hydraulic push rods A are installed in a circular array inside the cutter head. A cutting knife is installed on the left side of the hydraulic push rod A. The hydraulic push rod A and the cutting knife together form an excavation structure. A water collecting base is fixedly connected to the left side of the cutter head. The water collecting base is of a circular structure.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. When excavation is required, the hydraulic push rod B installed outside the drive can be pre-activated to push the protective plate outward using the pallet and the bracket, and the outward expansion of the protective plate contacts and supports the inner wall of the base. A pressure sensor is also provided on the pallet. When the base and the protective plate are overly squeezed, the pressure sensor installed inside the pallet will detect the change in the pressure data and synchronously activate the hydraulic push rod B to continue pushing the protective plate outward for support operations, thereby achieving the purpose of protecting the components inside the base from damage.

[0018] 2. When the protective plate expands outward, the motor A installed outside the protective plate can be synchronously activated to unwind the protective net wound around the roller, and the expansion of the protective plate and the protective net completes a more comprehensive support effect for the base, thereby preventing the problem of collapse inside the tunnel or damage to the device caused by foreign objects falling.

[0019] 3. By activating the motor B installed in the base to drive the rotation of the sieve box until the water in the slurry in the sieve box can be stored inside the separation tank using centrifugal force, and then connecting the soil extraction pipe to an external extraction pump to discharge the dehydrated soil, and synchronously opening the valve installed in the drain pipe to discharge the water in the separation tank. Separating the water flow and the soil and other excavation materials through the soil extraction pipe and the drain pipe can effectively reduce the subsequent labor intensity, thereby achieving the purpose of improving the excavation efficiency.

[0037] Wherein, a cutter head 3 is installed on the transmission shaft installed on the left side of the driver 9. The cutter head 3 is located on the left side of the transfer box 2. The cutter head 3 is a hollow structure inside, and a feeding pipe 4 is installed in an annular array inside the cutter head 3. The feeding pipe 4 communicates with the transfer box 2. A hydraulic push rod A 5 is installed in an annular array inside the cutter head 3. A cutting knife 6 is installed on the left side of the hydraulic push rod A 5. The hydraulic push rod A 5 and the cutting knife 6 together form an excavation structure. The left side of the cutter head 3 is fixedly connected with a water collecting seat 7. The water collecting seat 7 is a ring structure. By starting the motor B 24 installed in the base 1 to drive the sieve box 25 to rotate until the water in the slurry in the sieve box 25 can be stored inside the separation tank 23 by centrifugal force for storage, and then by connecting the soil extraction pipe 27 to an external extraction pump to discharge the dehydrated soil, and simultaneously opening the valve installed in the drain pipe 28 to discharge the water in the separation tank 23. Separating the water flow and excavation materials such as soil through the soil extraction pipe 27 and the drain pipe 28 can effectively reduce the subsequent labor intensity, thereby achieving the purpose of improving the excavation efficiency.

[0038] Among them, spray holes 8 are arranged in a circular array on the left side of the water collecting base 7. The spray holes 8 opened in the water collecting base 7 are used for spraying water. A pump water tank 10 is installed on the right side of the driver 9. The pump water tank 10 is communicated with the water collecting base 7 through a hose. A pump 11 is also installed on the right side of the pump water tank 10. The pump 11 is used for pumping air. An air extraction pipe 12 is installed at the top of the pump 11. The air extraction pipe 12 is communicated with the transfer box 2. The pump 11 and the air extraction pipe 12 together form an extraction structure. Hydraulic push rods B13 are installed in a circular array on the outer peripheral surface of the driver 9. A support plate 14 is installed on the side of the hydraulic push rod B13 far from the driver 9.

[0039] Among them, the hydraulic push rod B13 and the support plate 14 together form a lifting structure. A bracket 16 is installed on the side of the support plate 14 far from the hydraulic push rod B13 through a spring. A pressure sensor 15 is installed on the side of the support plate 14 close to the bracket 16. The pressure sensor 15 is electrically connected to the hydraulic push rod B13.

A motor A19 is installed on the outer side of the protective plate 17. When excavation is required, the hydraulic push rod B13 installed outside the driver 9 can be started in advance to use the support plate 14 and the bracket 16 to push the protective plate 17 outward, and the outward expansion of the protective plate 17 is in contact with the inner wall of the base 1 for support. A pressure sensor 15 is also provided on the support plate 14. The setting of the pressure sensor 15 can detect the change of the pressure data when the base 1 and the protective plate 17 are overly squeezed, and synchronously start the hydraulic push rod B13 to continue to push the protective plate 17 outward for support operation, thereby achieving the purpose of protecting the components inside the base 1 from damage.

[0040] During use: First, when full-face three-dimensional combined excavation operation of the tunnel is required, the base 1 and its internal components can be placed inside the tunnel to be excavated through a special machine, and the side with the cutter head 3 installed is placed facing the direction to be excavated.

[0041] Then, when tunnel excavation work is required, the hydraulic push rod A5 installed in the cutter head 3 can be started to push the cutter 6 outward, and the cutter 6 moves outward to protrude from the cutter head 3 and contact the tunnel. Then, the driver 9 installed in the base 1 is started to drive the rotation of the cutter head 3, and the cutter head 3 drives the cutter 6 to rotate for automated three-dimensional combined excavation, thereby achieving the purpose of improving the excavation efficiency;

[0042] During the excavation process, the pump water tank 10 installed on one side of the driver 9 can be connected to an external water source, and the pump water tank 10 is started synchronously to supply liquid through a hose into the inside of the water collecting seat 7 installed outside the cutter head 3. And when the liquid enters the inside of the water collecting seat 7, the water flow will be quickly sprayed onto the tunnel excavation surface through the spray holes 8 opened on the outside of the water collecting seat 7 to accelerate the excavation efficiency, thereby achieving the purpose of using earthmoving machinery and hydraulic machinery for excavation;

The pressure sensor 15 can detect the change of the pressure data when the base 1 and the protective plate 17 are overly squeezed, and the hydraulic push rod B13 is started synchronously to continue to push the protective plate 17 outward for support operation, thereby achieving the purpose of protecting the components inside the base 1 from damage;

[0044] When the protective plate 17 expands outward, the motor A19 installed outside the protective plate 17 can be started synchronously to unwind the protective net 20 wound around the roller 18, and the expansion of the protective plate 17 and the protective net 20 has completed a more comprehensive support effect on the base 1, thereby achieving the purpose of preventing the occurrence of problems such as tunnel collapse or foreign object falling and damaging the device;

[0045] As the cutter head 3 advances, the slurry generated during excavation will enter the inside of the transfer box 2 through the feed pipe 4 installed in the cutter head 3. The pump 11 installed outside the pump water tank 10 is started synchronously to evacuate the inside of the transfer box 2 through the air extraction pipe 12 to accelerate the entry of the slurry into the inside of the transfer box 2. At this time, the pump body 21 installed in the base 1 is started synchronously to quickly extract the slurry in the transfer box 2 through the extraction pipe 22 and supply it to the sieve box 25 through the supply pipe 26;

[0046] At this time, start the motor B24 installed in the base 1 to drive the sieve box 25 to rotate until the moisture in the mud in the sieve box 25 can be stored inside the separation tank 23 by centrifugal force. Then, connect the soil suction pipe 27 to an external extraction pump to discharge the dehydrated soil, and simultaneously open the valve installed in the drain pipe 28 to discharge the moisture in the separation tank 23. Separating the water flow from the excavated materials such as soil through the soil suction pipe 27 and the drain pipe 28 can effectively reduce the subsequent labor intensity, thereby achieving the purpose of improving the excavation efficiency.
