Description

Technical Field

[0001] This utility model relates to the field of tunnel boring machine cutterhead ring technology, and in particular to testing equipment for the inner ring production line of tunnel boring machine cutterhead ring. Background Technology

[0002] Subway and railway tunnels are mostly excavated using tunnel boring machines (TBMs), whose safety and speed advantages are becoming increasingly widespread. The cutterhead is the "teeth" of the TBM, breaking through hard rock and complex strata by rolling cutter blocks. Its lifespan is characterized by wear, requiring testing of the wear degree of the inner ring of the cutterhead.

[0003] Existing technologies, such as the shield machine cutter wear detection device disclosed in announcement number CN217156334U, include a cutter and a working platform. The cutter shaft is perpendicular to the platform, with one end clamped to the platform fixture and the other end connected to a drive motor. The platform is equipped with a detection table that can move left and right. A vertical lifting rod on the platform is equipped with a detection component, which can detect 360 degrees. The adjustable distance and height are adapted to different cutters, and the wear can be observed accurately and quickly.

[0004] However, this technical solution has the following problems in practical use: The fixture is used to hold the hob. One end of the cutter shaft is firmly clamped inside the fixture, while the other end is tightly connected to the drive motor, which is fixedly mounted on the surface of the work platform, effectively driving the hob to rotate stably. However, due to the lack of a structure to drive the rotation of the hob after clamping, the inspection unit can only perform eye-level inspection. If the size of the hob exceeds the camera's capture range, a blind spot will be created, affecting the comprehensiveness of the inspection. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the existing technology lacks a structure to drive the rotation of the roller cutter after clamping, and the detection unit can only perform horizontal inspection. If the size of the roller cutter exceeds the camera's capture range, a blind spot will be generated, affecting the comprehensiveness of the inspection. Therefore, this invention proposes an inspection device for the inner ring production line of the roller cutter ring of a tunnel boring machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: The testing equipment for the inner ring production line of the cutter head of a tunnel boring machine includes a base and a testing unit fixedly installed on the top of the base. A pair of concave seats are fixedly installed on the top of the base. A motor and a support rod are vertically slidably arranged on opposite sides of the two concave seats. The output end of the motor and the opposite side of the support rod are fixedly connected to the same fixed seat. A pair of fixed clamping blocks and moving clamping blocks for clamping the cutter head are provided on the fixed seat. The equipment also includes: A lifting assembly is mounted on the concave seat and is used to drive the second motor and the support rod to lift.

[0007] Preferably, a vertical plate is fixedly connected to the top of the fixed base, a cylinder is fixedly connected to the vertical plate, the two moving clamps are fixedly connected to the same transmission rod, and the transmission rod and the output end of the cylinder are fixedly connected.

[0008] Preferably, a connecting block is fixedly connected to the fixed base, and the connecting block and the fixed clamping block are fixedly connected.

[0009] Preferably, the lifting assembly includes: A lifting screw is rotatably connected to one of the concave seats; Motor 1 is fixedly connected to the top of the concave seat and is used to drive the lifting screw to rotate. A threaded block, one of which is threadedly connected to the lifting screw, and a second motor is fixedly connected to the threaded block.

[0010] Preferably, the lifting assembly further includes: A sliding opening is formed on the concave seat, and the threaded block and the sliding opening are vertically slidably connected; A slide rod is fixedly connected to another concave seat, and another threaded block is vertically slidably connected to the slide rod, while the support rod and the threaded block are rotatably connected.

[0011] Preferably, the fixed base has a limiting opening to facilitate the horizontal sliding of the transmission rod, and the transmission rod is U-shaped.

[0012] Compared with the prior art, the advantages of this utility model are as follows: This invention, through the arrangement of components such as a lifting assembly and a second motor, enables the first motor to drive the lifting screw to rotate, and the threaded block to drive the fixed seat and the hob to rise and fall, precisely matching the detection height of the detection unit. After the detection unit is started, when multi-angle detection is required, the second motor can be started to drive the fixed seat and the clamped workpiece to rotate smoothly around the axis of the support rod to complete the detection, effectively improving the comprehensiveness of the detection, reducing blind spots, and providing more complete detection coverage and more reliable results for the hob.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figures 1-3 The inspection equipment for the inner ring production line of the tunnel boring machine cutterhead includes a base 1 and an inspection unit 2 fixedly installed on top of the base 1. The inspection unit 2 includes components such as a camera and an LED light source, which are existing mature technologies and will not be described in detail here. A pair of concave seats 3 are fixedly installed on the top of the base 1. A motor 41 and a support rod 42 are vertically slidably arranged on opposite sides of the two concave seats 3. The support rod 42 cooperates with the motor 41 to jointly support the fixed seat 4 and provide solid support at the other end of the fixed seat 4, effectively balancing the load of the motor 41, preventing deformation or vibration caused by the cantilever structure, and enhancing the rigidity and stability of the overall structure. The output end of the motor 41 and the opposite side of the support rod 42 are fixedly connected to the same fixed seat 4. The motor 41 provides rotational power to the fixed seat 4, enabling the fixed seat 4 to achieve precise positioning at any angle, thereby meeting the inspection requirements of the workpiece in different positions. The fixed base 4 is equipped with a pair of fixed clamping blocks 6 and movable clamping blocks 7 for holding the hob. The movable clamping block 7 cooperates with the fixed clamping block 6 to clamp and release the hob. The movement is flexible and can respond quickly under the drive of the cylinder 72, achieving reliable clamping and rapid release. It also includes; The lifting assembly is mounted on the concave seat 3 and is used to drive the motor 41 and the support rod 42 to lift.

[0017] A vertical plate 71 is fixedly connected to the top of the fixed base 4, and a cylinder 72 is fixedly connected to the vertical plate 71. Two movable clamping blocks 7 are fixedly connected to the same transmission rod 73, and the output end of the transmission rod 73 and the cylinder 72 are fixedly connected.

[0018] A connecting block 5 is fixedly connected to the fixed base 4, and the connecting block 5 and the fixed clamping block 6 are fixedly connected.

[0019] Reference Figures 1-2 The lifting assembly includes: a lifting screw 31, a motor 32, and a threaded block 33.

[0020] A lifting screw 31 is rotatably connected to one of the concave seats 3; a motor 32 is fixedly connected to the top of the concave seat 3, and the motor 32 drives the lifting screw 31 to rotate; the motor 32 driving the lifting screw 31 to rotate enables automated and precise control of the lifting height of the clamped and fixed hobbing cutter. A threaded block 33 is threadedly connected to the lifting screw 31, and a second motor 41 is fixedly connected to the threaded block 33.

[0021] Reference Figures 1-2 The lifting assembly also includes: slide 34 and slide bar 35.

[0022] The sliding opening 34 is formed on the concave seat 3, and the threaded block 33 and the sliding opening 34 are vertically slidably connected; the setting of the sliding opening 34 ensures that the threaded block 33 can move stably vertically in the axial direction of the lifting screw 31. The slide rod 35 is fixedly connected to another concave seat 3, and another threaded block 33 and the slide rod 35 are vertically slidably connected, and the support rod 42 and the threaded block 33 are rotatably connected.

[0023] The fixed base 4 has a limiting opening 74 to facilitate the horizontal sliding of the transmission rod 73, which is U-shaped. The limiting opening 74 ensures the stable horizontal movement of the transmission rod 73; the U-shaped design of the transmission rod 73 is to avoid obstructing the installation of the hob.

[0024] The functional principle of this utility model can be explained through the following operation methods: Place the inner ring workpiece of the tunnel boring machine cutter head on the fixed seat 4 (connecting motor 2 41 and support rod 42), so that one side of the workpiece is in contact with the fixed clamping block 6 (fixed to the fixed seat 4 by the connecting block 5). Clamping and fixing: Activate the cylinder 72 on the vertical plate 71 (top of the fixed base 4), and its output end pushes the U-shaped transmission rod 73. The transmission rod 73 slides horizontally along the limiting port 74 of the fixed base 4, driving the two moving clamping blocks 7 to move closer to the fixed clamping block 6 until the workpiece is clamped. Height adjustment: Start the motor 32 on the concave seat 3 (top of base 1) to drive the lifting screw 31 to rotate. The threaded block 33 connected to the motor 41 slides vertically along the slide 34. The threaded block 33 connected to the support rod 42 slides synchronously along the slide rod 35, driving the fixed seat 4 and the workpiece to rise and fall until they are adapted to the detection height of the detection unit 2 (top of base 1). Inspection operation: The inspection unit 2 starts the inspection. If multi-angle inspection is required, the motor 41 is started to drive the fixed base 4 and the workpiece to rotate around the axis of the support rod 42 to complete the full inspection. After the inspection is completed, the cylinder 72 is reversed to release the workpiece and remove the inner ring of the tool ring that has been inspected.
