Description

Technical Field

[0001] This utility model relates to the field of cutter head installation technology, and specifically to a cutter head tool mounting device. Background Technology

[0002] With the rapid development of urban transportation, railways, highways, water conservancy, and municipal engineering projects both domestically and internationally, the market and application of tunneling machinery are becoming increasingly widespread. Tunnel boring machines (TBMs) are comprehensive equipment used for continuous operation, including mechanical rock breaking, muck removal, and support. The TBM cutterhead is the tunneling system, with dozens or even hundreds of cutters arranged at spatial angles to achieve the equipment's tunneling function. Since the cutters have a uniform shape, post-welding machining is difficult; therefore, they are usually machined before welding and then welded onto the cutterhead. The cutter arrangement on the cutterhead includes both surface and circumferential directions. The cutter surface is arc-shaped, and even on complex cutterheads, cutters with different functions may have different heights, making it difficult to level the cutter height. The current method involves marking lines around the cutters for positioning welding. However, due to manufacturing errors and overall post-welding errors in the cutter holder welded components, the distance between cutters also needs to be marked individually on the cutter holder surface next to the welded position. This results in time-consuming, slow, and low-accuracy riveting and positioning.

[0003] In summary, there is an urgent need to provide a tool holder for a cutter head to solve the problems existing in the prior art. Utility Model Content

[0024] Example See Figure 1 This embodiment provides a cutter head tool mounting device, including a rotary lifting system 1, a tool mounting arm assembly 2, a counterweight arm assembly 3, and a tool die 4; the rotary lifting system 1 is connected to the cutter head 5; the tool mounting arm assembly 2 is connected to the rotary lifting system 1; the counterweight arm assembly 3 is connected to the rotary lifting system 1, and the counterweight arm assembly 3 and the tool mounting arm assembly 2 are arranged in opposite directions; the tool die 4 is mounted on the tool mounting arm assembly 2 and is used to inspect and position the tool 5.1.

[0025] The cutter head mounting device provided in this embodiment realizes the height adjustment and 360° rotation of the cutter arm assembly 2 and the counterweight arm assembly 3 through the rotary lifting system 1, thereby realizing the height adjustment and 360° rotation of the die 4, which meets the inspection and positioning of the cutter 5.1 at different positions, improves the positioning efficiency and positioning accuracy, and realizes the rapid positioning and riveting of the cutter 5.1.

[0026] See Figure 2 and Figure 3 The rotary lifting system 1 includes a base 1.1, a lifting mechanism, and a rotary mechanism. The base 1.1 is mounted on the center of the cutter head 5 via a mounting plate 1.2. The lifting mechanism is connected to the base 1.1, and the rotary mechanism is connected to the lifting mechanism. The cutter arm assembly 2 and the counterweight arm assembly 3 are respectively connected to the rotary mechanism. The rotary mechanism and the lifting mechanism enable the cutter arm assembly 2 and the counterweight arm assembly 3 to rotate and lift 360°.

[0027] In this embodiment, the base 1.1 includes a base plate and a support column, with the base plate disposed at the bottom end of the support column; the base plate is detachably connected to the mounting plate 1.2 by bolts, and the mounting plate 1.2 is detachably connected to the center of the cutter head 5 by bolts; a leveling component 6 is provided between the mounting plate 1.2 and the cutter head 5, and the leveling component 6 is preferably a leveling bolt, which is used to level the device by adjusting the extension length of the leveling bolt.

[0028] In this embodiment, see Figure 3 The lifting mechanism includes a sliding sleeve 1.3, a connecting plate 1.4, and a screw 1.5; the sliding sleeve 1.3 is sleeved on the support column of the base 1.1 and slidably connected to the support column; the connecting plate 1.4 is fixedly connected to the top end of the sliding sleeve 1.3. The screw 1.5 is rotatably connected to the support column of the base 1.1; specifically, a limiting plate is provided at the top of the support column, and an annular groove is provided at the bottom of the screw 1.5. The limiting plate is embedded in the annular groove, and the screw 1.5 can rotate circumferentially relative to the limiting plate along the annular groove. At the same time, the limiting plate restricts the movement of the screw 1.5 along its axial direction. The screw 1.5 is threadedly connected to the connecting plate 1.4. By rotating the screw 1.5, the connecting plate 1.4 causes the sliding sleeve 1.3 to move up and down, which in turn drives the rotary mechanism connected to the sliding sleeve 1.3 and the tool mounting arm assembly 2 and counterweight arm assembly 3 connected to the rotary mechanism to rise and fall, thereby realizing the height adjustment of the die 4. (See [reference]) Figure 4 .

[0029] Preferably, in this embodiment, the lifting mechanism further includes a limiting component 1.6, which is preferably a limiting pin. The limiting pin is inserted into the corresponding through holes on the support column and the sliding sleeve 1.3 to limit the rising height of the sliding sleeve 1.3 and prevent the connecting plate 1.4 from unscrewing the screw 1.5. At the same time, the limiting pin can also limit the relative rotation between the sliding sleeve 1.3 and the support column.

[0030] See Figure 3 The rotary mechanism includes one or two or more mounting seats 1.7 arranged sequentially along the height direction of the support column of the base 1.1. In this embodiment, there are two sets of mounting seats 1.7, which are located at the two ends of the sliding sleeve 1.3 respectively. The mounting seats 1.7 are rotatably connected to the support column of the base 1.1 through self-aligning bearings. The tool arm assembly 2 and the counterweight arm assembly 3 are respectively connected to the mounting seats 1.7 to achieve 360° rotation.

[0031] See Figure 5 In this embodiment, the tool mounting arm assembly 2 includes one or more tool mounting arms 2.1 connected radially along the cutter disc 5 and a die mounting plate 2.2. The tool mounting arm 2.1 is connected to the mounting base 1.7. The die mounting plate 2.2 is connected to the tool mounting arm 2.1. The die 4 is mounted on the die mounting plate 2.2. To ensure accurate positioning of the die 4, multiple mounting holes are provided at equal intervals on the die mounting plate 2.2. The die 4 is connected to the mounting holes by bolts.

[0032] See Figure 6 The counterweight arm assembly 3 includes one set of counterweight arms 3.1 or two or more sets of counterweight arms 3.1 connected radially along the cutter head 5. The counterweight arms 3.1 are connected to the mounting base 1.7, and the counterweight arms 3.1 and the cutter arm 2.1 are arranged in opposite directions. The counterweight arm assembly 3 and the cutter arm assembly 2 are used together to ensure that the center of gravity of the device remains balanced during use and to prevent the device from tipping over during use.

[0033] In this embodiment, when the cutter head diameter is <10m, one assembled cutter arm 2.1 is provided to make it easier to use; at the same time, a set of counterweight arms 3.1 used in conjunction with the assembled cutter arm 2.1 is also provided; when the cutter head diameter is >10m, two assembled cutter arms 2.1 are provided, and two sets of counterweight arms 3.1 used in conjunction with the assembled cutter arm 2.1 are also provided.

[0034] See Figure 1 In this embodiment, a sliding block 3.2 is provided on the counterweight arm 3.1. Because the diameter of the cutter head is different, the installation position of the die 4 on the die mounting plate 2.2 is also different. At this time, the sliding block 3.2 can be finely adjusted to achieve the leveling of the device.

[0035] See Figure 1In this embodiment, the die 4 is an inverted L-shape. The detection surface of the die 4 includes a flat surface and an arc surface, which match the trajectory points of the cutting tool. The detection surface of the die 4 is provided with toothed grooves (with equal tooth spacing), which match the tip of the cutting tool 5.1. The positioning detection of the cutting tool 5.1 is achieved by confirming whether the tip of the cutting tool 5.1 is embedded in the toothed groove. The size and specifications of the die 4 can be set according to actual needs.

[0036] See Figure 2 and Figure 5 In this embodiment, a leveling detection component is also included. The leveling detection component includes a level 7 (using a cross bubble level) and a leveling detection plate 8. The level 7 is mounted on the mounting base 1.7 of the rotary lifting system 1. The leveling detection plate 8 is mounted on the tool mounting arm 2.1 of the tool mounting arm assembly 2. Preferably, multiple leveling detection plates 8 are provided on the tool mounting arm 2.1. When the device is leveled, the levelness of at least 3 leveling detection plates 8 is <0.5mm.

[0037] In practical applications: First, based on the diameter of the cutter head 5 and the specifications of the die 4, determine the quantity of the mounting arm 2.1 and the counterweight arm 3.1, and assemble them with the rotary lifting system 1. After installing the mounting arm 2.1 (with the die mounting plate 2.2 installed on it) and the counterweight arm 3.1, install the corresponding die 4 according to the theoretical position. Install the device at the center of the cutter holder via the mounting plate 1.2, and level the device using the leveling bolts. Observe the level 7 to ensure vertical and horizontal balance, and at the same time, ensure that the levelness of at least 3 leveling test plates 8 is <0.5mm. After leveling, fix the mounting plate 1.2 to the cutter holder, see [reference]. Figure 7 ; Next, place tool 5.1 according to its riveting position on the tool holder, and adjust the height of the die 4 by adjusting screw 1.5 to match the theoretical height of tool 5.1; the die 4 is used to verify the precise position of tool 5.1. (See [link to documentation]). Figure 8 and Figure 9 ; Then, the horizontal angle of the die 4 is adjusted by a rotary mechanism, and the remaining cutters 5.1 are inspected and riveted in sequence; the angled cutters are inspected through the arc surface of the die 4, see [link to relevant documentation]. Figure 10 and Figure 11 ; Finally, complete the riveting of all the cutting tools 5.1 in sequence.

[0038] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
