Description

Technical Field

[0001] The present invention relates to the technical field of shield engineering machinery component machining, and in particular to shield engineering machinery component machining equipment. Background Art

[0002] A tunnel boring machine, also known as a tunnel boring machine, is a large-scale mechanical equipment used to excavate tunnels in underground projects. It can work in various geological conditions, including soft soil, hard rock, etc., and can effectively control surface subsidence. The shield machine consists of multiple key components, each of which plays a specific role to ensure the normal operation and safety of the machine.

[0003] The cutting head is the front-end component of the shield machine, which is responsible for directly cutting or crushing rocks and soil. The cutting head is equipped with different types of cutting tools, such as hobs, scrapers, tooth cutters, etc., to adapt to different geological conditions. The hob is the key component of the cutting head for crushing rocks. The hob will roll with the rotation of the cutting head and crush the rock in front through its huge pressure and rotational motion. A cutter ring is installed on the periphery of the hob. The hob ring is a vital component of the shield machine, and its performance directly affects the efficiency and cost of the entire tunnel excavation process. Due to the harsh working environment of the hob ring, its surface often produces some wear, dents or cracks. In order to maintain the normal use of the hob ring, it is necessary to perform grinding and maintenance processing on the hob ring.

[0004] There are many types of existing hob cutter ring grinding and maintenance processing equipment, including CNC grinders, tool grinders and grinding wheel dressers. Although these processing equipment can grind and maintain hob cutter rings well, they can generally only complete the grinding of one set of cutter rings at a time, and the work efficiency needs to be improved. At the same time, hob cutter rings are large parts, and the grinding tools used are small, so the friction contact area between the tool and the hob cutter ring is small. Using small tools to process large hob cutter rings requires further improvement in work efficiency. At the same time, the existing processing equipment requires secondary processing and separation of coolant and grinding chips, and the working steps are relatively cumbersome and inconvenient to use.

DETAILED DESCRIPTION

[0033] The embodiments of the present invention are described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered by the claims.

[0034] See Figure 1 and Figure 9 A shield engineering machinery component machining equipment includes a shell 1, a main beam 3 is fixedly connected between the left and right side walls of the shell 1, a vertical plate 7 is fixedly connected to the upper middle side of the main beam 3, and a grinding mechanism 2 for grinding two sets of knife rings is commonly provided on the left and right sides and on the vertical plate 7. A cooling mechanism 4 for cooling the knife ring grinding is provided on the upper end of the vertical plate 7.

[0035] See Figure 1 、 Figure 2 、 Figure 5 、 Figure 8 and Figure 9The grinding mechanism 2 includes a rotating shaft 24 rotatably connected to the vertical plate 7, and the front end of the rotating shaft 24 is detachably fixedly connected to the special-shaped grinding roller 22. The outer contour of the special-shaped grinding roller 22 fits the outer contour of the knife ring. The left and right sides of the special-shaped grinding roller 22 are jointly provided with a clamping assembly 21 for clamping the two sets of knife rings. The clamping assembly 21 includes a round seat 212 movably arranged on the left and right sides of the vertical plate 7. A plurality of guide grooves 2121 are equidistantly provided on the circumference of the front side wall of the round seat 212. A stop seat 213 is slidably connected in the guide groove 2121. The outer end of the stop seat 213 contacts the inner ring wall of the knife ring. The rear sides of the left and right round seats 212 are jointly provided with a driving assembly 23 for controlling the synchronous rotation of the two and the special-shaped grinding roller 22.

[0036] During specific operation, the special-shaped grinding roller 22 is driven to rotate by rotating shaft 1 24, and the special-shaped grinding roller 22 grinds the outer surfaces of the two sets of knife rings synchronously, and the knife rings are fixed by the respective support seats 213 on the same round seat 212. During specific use, the special-shaped grinding roller 22 that matches the outer contour of the actual knife ring is selected in a targeted manner.

[0037] See Figure 1 、 Figure 6 、 Figure 7 The cooling mechanism 4 includes a movable rod 42 that slides forward and backward and passes through the upper end of the vertical plate 7. The front end of the movable rod 42 is fixedly connected to a two-way electric push rod 47. The left and right output ends of the two-way electric push rod 47 are fixedly connected to a mounting plate 44. A number of nozzles 45 spraying downward are fixedly connected to the mounting plate 44 at equal intervals. The common pipeline of the several nozzles 45 is connected to the liquid distribution pipe 43. The middle pipeline of the liquid distribution pipe 43 is connected to a liquid inlet pipe 46. The liquid inlet pipe 46 is connected to an external coolant delivery system (the external coolant delivery system is not shown in the figure).

The cooling mechanism 4 also includes a separation component 41 arranged on the lower side of the main beam 3 for separating grinding chips and coolant.

[0038] During specific operation, the coolant is transported to the liquid inlet pipe 46 through the external coolant delivery system, and the coolant is transported to each nozzle 45 by the liquid distribution pipe 43. The nozzle 45 sprays the coolant onto the contact position between the special-shaped grinding roller 22 and the cutter ring. When the type of the special-shaped grinding roller 22 and the cutter ring changes, the position of the contact gap between the two will also change. The bidirectional electric push rod 47 changes the left and right position of the nozzle 45 to adapt to the change in the position of the contact gap between the special-shaped grinding roller 22 and the cutter ring.

[0039] See Figure 2 、 Figure 3 and Figure 4, the inner end of each of the said seats 213 is commonly provided with a tightening component 214 for controlling its movement along the guide groove 2121; the tightening component 214 includes a mounting column 2122 fixedly connected to the center of the round seat 212, and a turntable 2141 is rotatably connected to the mounting column 2122, and a vortex track 2143 is integrally fixedly connected to the front side of the turntable 2141, and the vortex track 2143 is meshed with a meshing block 2142 corresponding to the guide groove 2121 on the one-to-one basis. The meshing block 2142 is fixedly connected to the seat 213 in a one-to-one correspondence, and a bevel gear ring 2146 is fixedly connected to the rear side of the turntable 2141. The outer periphery of the bevel gear ring 2146 is meshed with a bevel gear 1 2144, and the bevel gear 1 2144 is fixedly connected to the output end of the motor 1 2145, and the motor 1 2145 is fixedly connected to the rear wall of the round seat 212.

[0040] During specific operation, the motor 2145 drives the bevel gear 2144 to rotate and control the bevel gear ring 2146 to rotate, and the bevel gear ring 2146 drives the turntable 2141 to rotate. The vortex track 2143 on the turntable 2141 controls each engaging block 2142 to synchronously drive each retaining seat 213 to move along the guide groove 2121, and the retaining seat 213 supports and locks the inner ring wall of the cutter ring.

[0041] See Figure 1 and Figure 2 The upper and lower sides of the round seats 212 on the left and right sides are jointly provided with a close component 211 for controlling the two to approach or move away from the special-shaped grinding roller 22; the close component 211 includes a movable ring seat 2112 rotatably connected to the outer periphery of the left and right round seats 212, and the upper sides of the movable ring seats 2112 on the left and right sides are symmetrically threadedly connected to the bidirectional screw rod 2111, and the bidirectional screw rod 2111 is rotatably connected between the left and right walls of the shell 1, and the lower sides of the movable ring seats 2112 on the left and right sides are slidably connected to the guide rod 2113, and the guide rod 2113 is fixedly connected between the left and right walls of the shell 1. One end of the bidirectional screw rod 2111 extends to the outside of the shell 1 and is fixedly connected to the output end of the motor 2 5.

[0042] During specific operation, the bidirectional screw rod 2111 is controlled to rotate by the motor 25, and the bidirectional screw rod 2111 drives the movable ring seats 2112 on the left and right sides to move in opposite directions, and the round seat 212 is driven to move by the movable ring seat 2112, and the round seat 212 drives the cutter ring to approach the special-shaped grinding roller 22, which can ensure that different types of cutter rings are in full contact with the special-shaped grinding roller 22 to ensure the grinding effect. When the cutter ring is away from the special-shaped grinding roller 22, the special-shaped grinding roller 22 does not interfere with the disassembly and assembly of the cutter ring.

[0043] See Figure 5 and Figure 8The driving assembly 23 includes a bevel gear disc 231 fixedly connected to the center of the rear side of the round seat 212, the periphery of the bevel gear disc 231 is meshed with a bevel gear 232, the center of the bevel gear 232 is fixedly connected to a connecting sleeve 235, the connecting sleeve 235 is rotatably connected to the support plate 233, and the support plate 233 is fixedly connected to the rear wall of the round seat 212. The centers of the connecting sleeves 235 on the left and right sides slide together and are limitedly connected to the limiting sliding shaft 234, and the limiting sliding shaft 234 is rotatably connected between the left and right walls of the shell 1. One end of the limiting sliding shaft 234 extends to the outside of the shell 1 and is fixedly connected to the output end of the motor three 6. The motor three 6 is fixedly connected to the outside of the shell 1. The limiting sliding shaft 234 is fixedly connected to the position of the vertical plate 7 corresponding to the limiting sliding shaft 234. The front side of the bevel gear three 236 is meshed with the bevel gear four 25, and the bevel gear four 25 is fixedly connected to the rotating shaft 1 24.

[0044] During specific operation, the limiting sliding shaft 234 is controlled to rotate by the motor three 6, and the limiting sliding shaft 234 controls the connecting sleeve 235 to drive the bevel gear two 232 to rotate, and the bevel gear two 232 drives the bevel gear disk 231 to rotate, and the rotation of the bevel gear disk 231 drives the knife ring to rotate, thereby changing the grinding position of the knife ring. At the same time, the limiting sliding shaft 234 drives the bevel gear three 236 to rotate and control the rotation of the bevel gear four 25, and the bevel gear four 25 drives the rotating shaft one 24 to control the rotation of the special-shaped grinding roller 22, thereby completing the grinding work.

[0045] See Figure 5 and Figure 8 The diameter of the bevel gear 231 is much larger than the diameter of the bevel gear 232. The diameters of the bevel gear 232, the bevel gear 3 236 and the bevel gear 4 25 are the same. The installation directions of the bevel gear 232 and the bevel gear 3 236 are opposite. The diameters of the bevel gear 5 4155 and the bevel gear 6 486 are the same and smaller than the diameter of the bevel gear 4 25.

[0046] During specific operation, the transmission ratio of bevel gear 232 and bevel gear disc 231 is relatively small, which can make the knife ring produce a smaller rotation speed to ensure the grinding effect. Bevel gear 232, bevel gear 3 236 and bevel gear 4 25 are on the same axis, with the same diameter and consistent transmission effect. Bevel gear 232 and bevel gear 3 236 are installed oppositely, which can make the knife ring and the special-shaped grinding roller 22 produce opposite rotation, which is beneficial to grinding. Bevel gear 5 4155 and bevel gear 6 486 have smaller diameters, which can avoid interfering with the rotation of bevel gear 4 25.

[0047] See Figure 7The reciprocating moving component 48 includes a mounting seat 484 fixedly connected to the rear end of the movable rod 42, and a section of the movable rod 42 between the mounting seat 484 and the vertical plate 7 is sleeved with a spring 485. A contact wheel 481 is rotatably connected in the mounting seat 484, and a cam 482 is rollingly connected to the rear side of the contact wheel 481. The lower side of the cam 482 is fixedly connected to a rotating shaft three 483, and the rotating shaft three 483 is rotatably connected to the rear side of the vertical plate 7 through a fixed block. The lower end of the rotating shaft three 483 is fixedly connected to a bevel gear six 486, and the bevel gear six 486 is meshed with the bevel gear three 236.

[0048] During specific operation, bevel gear three 236 drives bevel gear six 486 to rotate, and bevel gear six 486 drives shaft three 483 to control the rotation of cam 482, and spring 485 keeps the contact wheel 481 and cam 482 in close contact. When the cam 482 changes its contact position with the contact wheel 481, the movable rod 42 is controlled to move back and forth, and the movable rod 42 drives the nozzle 45 to change the front and rear spray positions, ensuring the uniformity of the spray in the front and rear directions, ensuring that the contact position between the special-shaped grinding roller 22 and the knife ring is fully cooled, and can also adapt to the grinding of knife rings with varying thicknesses.

[0049] See Figure 1 、 Figure 2 、 Figure 5 and Figure 8 The separation assembly 41 includes a separation bucket 412 hinged on the lower side of the main beam 3, the separation bucket 412 is tilted forward, the separation bucket 412 is hollow inside, and a filtrate plate 411 is installed on the upper opening of the separation bucket 412, the lower end of the separation bucket 412 is fixedly connected to a chip collection bucket 413, a pipe on one side wall of the lower end of the separation bucket 412 is connected to a liquid outlet pipe 414, and a vibration component 415 for controlling its vibration is provided at the bottom of the separation bucket 412; the vibration component 415 includes a fixed block rotatably connected to the rear side of the vertical plate 7 The upper end of the rotating shaft 4151 is fixedly connected to the bevel gear 5 4155, and the bevel gear 5 4155 is meshed with the bevel gear 3 236. The lower end of the rotating shaft 4151 is fixedly connected to the short swing plate 4152, and the end of the short swing plate 4152 away from the rotating shaft 2 4151 is hinged with a connecting arm 4153, and the end of the connecting arm 4153 away from the short swing plate 4152 is hinged to the mounting block 4154 through a sphere, and the mounting block 4154 is fixedly connected to the bottom of the separation bucket 412.

[0050] During specific operation, the grinding chips and coolant will fall directly onto the filtrate plate 411. There are a large number of holes on the filtrate plate 411. Part of the coolant will directly enter the separation bucket 412 through the holes, and the grinding chips will slide along the filtrate plate 411 into the chip collecting bucket 413, and the bevel gear three 236 will drive the bevel gear five 4155 to rotate. The bevel gear five 4155 will drive the rotating shaft two 4151 to rotate and control the short swing plate 4152 to drive the connecting arm 4153 to reciprocate and pull the separation bucket 412 around the main beam 3 to rotate at a small angle, so as to achieve a vibration effect. Under the action of vibration, the grinding chips can move downward quickly, and the coolant mixed in it will also be fully separated out and enter the separation bucket 412, thereby improving the collection effect of the coolant. The collected coolant is discharged by the liquid outlet pipe 414, and the collected coolant can be cooled and recycled again (the specific cooling method can be air cooling).

[0051] When in use: S1: Place the two sets of cutter rings on the left and right side clamping assemblies 21 respectively, and use motor 2145 to drive bevel gear 2144 to rotate and control the bevel gear ring 2146 to rotate, and the bevel gear ring 2146 drives the turntable 2141 to rotate, and the vortex track 2143 on the turntable 2141 controls each meshing block 2142 to synchronously drive each stop 213 to move along the guide groove 2121, and the stop 213 supports and locks the inner ring wall of the cutter ring. Before locking, use a spirit level to coplanarly position the special-shaped grinding roller 22 and the cutter ring.

[0052] S2: Motor 2 5 is used to control the rotation of the bidirectional screw rod 2111, which drives the movable ring seats 2112 on the left and right sides to move in opposite directions, and the movable ring seat 2112 drives the round seat 212 to move, and the round seat 212 drives the knife ring to approach the special-shaped grinding roller 22 until the knife ring and the special-shaped grinding roller 22 are fully fitted. At the same time, the limiting sliding shaft 234 is controlled to rotate by motor 3 6, and the limiting sliding shaft 234 controls the connecting sleeve 235 to drive the bevel gear 2 232 to rotate, and the bevel gear 232 drives the bevel gear disk to rotate, and the bevel gear disk 231 rotates to drive the knife ring to rotate, and the limiting sliding shaft 234 simultaneously drives the bevel gear 3 236 to rotate and control the bevel gear 4 25 to rotate, and the bevel gear 4 25 drives the rotating shaft 1 24 to control the special-shaped grinding roller 22 to rotate for grinding.

[0053] S3: The coolant is delivered to the liquid inlet pipe 46 through the external coolant delivery system, and the coolant is delivered to each nozzle 45 by the liquid distribution pipe 43. The nozzle 45 sprays the coolant to the contact position between the special-shaped grinding roller 22 and the cutter ring. The left and right positions of the nozzle 45 are changed by the bidirectional electric push rod 47 to adapt to the position change of the contact gap between the special-shaped grinding roller 22 and the cutter ring. The bevel gear three 236 drives the bevel gear six 486 to rotate, and the bevel gear six 486 drives the rotating shaft three 483 to control the rotation of the cam 482.
