Description

[0002] Cutters are installed on the cutter head of the shield machine. During the working process, the cutters will be worn in different types and degrees due to impact and friction. Detecting the wear of the cutters and judging whether they can continue to be used play an important role in the operation of the shield machine.

[0003] The existing shield machine cutter head detection device has the advantage of being able to detect horizontally. It solves the problem that the original tool wear detection device cannot move and is inconvenient for detection. However, after the device is installed and fixed, it can only detect horizontally and cannot move in multiple directions comprehensively to detect cutters at different positions. Moreover, since the detection surface of the cutter is often not a plane, accurate data cannot be obtained by detecting in a single direction. Therefore, improvements are made for the above problems.

The vertical movement device is located on the outside. A rope is connected to the vertical movement device, and one end of the rope is connected to the bracket. An L-shaped connecting plate is connected to the side of the support plate close to the vertical movement device. A first elastic telescopic rod is arranged on the top of the L-shaped connecting plate. A telescopic device is connected to one side of the horizontal movement device, and a detection probe is installed on the telescopic device;

[0007] A conversion device is also arranged on the support plate for adjusting the position of the rack;

[0008] Among them, the vertical movement device includes two support blocks arranged at the top of one end of the support plate. A rotating bearing is rotatably installed between the two support blocks. A second gear and a pulley are fixedly sleeved on the rotating bearing. A driving plate is also arranged at one end of the support plate. A screw rod is installed on the driving plate, and the screw rod passes through the middle of the rotating bearing and meshes with the rotating bearing.

[0009] As a further solution of the present invention: the first elastic telescopic rod and the vertical moving device are on the same horizontal plane.

[0010] As a further solution of the present invention: the horizontal moving device includes a sliding plate, the sliding plate is slidably arranged on the support plate, a motor is fixedly arranged on the sliding plate, two output ends of the motor are respectively connected with a first gear and a telescopic device, a conical rubber block is connected to one side of the sliding plate close to the vertical moving device, a telescopic rod is arranged below one side of the sliding plate close to the telescopic device, the other end of the telescopic rod is connected with a pushing block, and the bottom end of the pushing block abuts against the conversion device.

[0011] As a further solution of the present invention: the rack is located below the first gear, and the first gear meshes with the rack.

[0012] As a further solution of the present invention: a clamping plate is arranged on the output end of the first elastic telescopic rod, and the clamping plate and the second gear are at the same height.

[0013] As a further solution of the present invention: the telescopic device includes an electric telescopic rod, the output end of the electric telescopic rod is connected with an inclined rod, a detection probe is arranged at the top end of the inclined rod, and a protrusion is rotatably installed on the cylindrical surface of the output end of the electric telescopic rod.

[0014] As a further solution of the present invention: the conversion device includes a flat plate, the flat plate is connected to the bottom surface of the support plate, a positioning block is slidably arranged in the middle of the flat plate, a second elastic telescopic rod is installed on the flat plate, and one end of the second elastic telescopic rod is connected with the positioning block, a conical block is arranged at the top end of the positioning block, an inclined surface is arranged on the top surface of the conical block, the inclined surface contacts with the rack, and a moving long plate is connected to one end of the positioning block far away from the second elastic telescopic rod, and the moving long plate abuts against the pushing block.

[0015] The beneficial effects of the present invention:

[0016] In the present invention, the electric telescopic rod controls the engagement state of the second gear through the protrusion, and the motor drives the first gear to move on the rack to control the relative movement of the conical rubber block with respect to the driving plate. The conical rubber block cooperates with the gravity of the support plate itself, so that the driving plate can be controlled to move in different directions to drive the screw rod to rotate in different directions. Finally, the rope arranged on the pulley can be contracted or released to adjust the height of the detection probe, avoiding the problem that the detection device cannot move in multiple directions to detect tools at different positions.

[0017] In the electric telescopic rod of the present invention, the setting of controlling the up-and-down movement of the rack through the protrusion enables the electric telescopic rod to drive the protrusion to squeeze the push block, driving the moving long plate to move towards the elastic telescopic rod and squeezing the positioning block, causing the conical block to move towards the elastic telescopic rod. The movement of the conical block drives the rack to move downward and disengage from the first gear. Subsequently, the motor drives the electric telescopic rod to rotate, driving the inclined rod to rotate and changing the inclination angle and the local vertical position of the detection probe, avoiding the problem that the detection surface of the tool is often not flat and accurate data cannot be obtained through single-direction detection.

[0018] In the present invention, the electric telescopic rod is provided with a setting for changing its state by squeezing different components through the protrusion. By squeezing the push block through the protrusion, the position of the electric telescopic rod will not be changed during the rotation of the inclined rod driven by the motor. By squeezing the clamping plate through the protrusion, the motor drives the first gear to move on the rack, driving the driving plate to move and thereby controlling the telescopic release of the rope. One motor cooperates with different telescopic states of the electric telescopic rod to control the change of the horizontal and vertical heights and the adjustment of the inclination angle of the detection probe.

[0019] In the present invention, the front end of the conical rubber block can enter the small hole on the driving plate, increasing the effective contact area between the conical rubber block and the driving plate, and enabling the conical rubber block to better regulate the movement state of the driving plate.

A vertical moving device 5 is fixedly arranged on the upper surface of the support plate 2 near one end of the support 1. A rope 6 is connected to the vertical moving device 5. The other end of the rope 6 is arranged on the connecting block at the top end of the support 1 beside the vertical moving device 5. The main part of the rope 6 is vertically arranged.

[0033] Further, as Figure 2As shown in the figure, an L-shaped connecting plate is fixedly connected to one side of the support plate 2 close to the vertical moving device 5. A first elastic telescopic rod 7 is arranged at the top of the L-shaped connecting plate. The first elastic telescopic rod 7 is located beside the vertical moving device 5 and they are on the same horizontal plane. The above-mentioned telescopic device 8 is fixedly connected to one side of the horizontal moving device 4 close to the first elastic telescopic rod 7. A detection probe 9 is installed on the output end of the telescopic device 8. The detection range of the detection probe 9 can be further expanded through the telescopic device 8. During the specific detection process, the detection probe 9 is used to detect the wear of the shield machine cutter, and the detection result is displayed through an external display.

[0034] Furthermore, a conversion device 100 is also arranged on the support plate 2 for adjusting the position of the rack 3.

[0035] Even further, as Figure 2 shown, the above-mentioned horizontal moving device 4 includes a slide plate 41, a motor 42, a first gear 43, a conical rubber block 44, a telescopic rod 45 and a push block 46; wherein the slide plate 41 is slidably arranged in the third chute of the support plate 2, and the slide plate 41 can move horizontally in the third chute of the support plate 2; and a motor 42 is fixedly arranged on the slide plate 41. The motor 42 is a double-shaft motor, and two output ends of the motor 42 are respectively connected to a first gear 43 and a telescopic device 8. The first gear 43 can be engaged with the rack 3 located below it; a first mounting plate is connected to one side of the slide plate 41 close to the vertical moving device 5, and a conical rubber block 44 is connected to the top of the first mounting plate. The conical rubber block 44 is arranged horizontally, and the output end of the conical rubber block 44 is a cone, which can be deformed when being extruded during the specific movement process; a telescopic rod 45 is arranged below one side of the slide plate 41 close to the telescopic device 8, and the telescopic rod 45 is arranged horizontally, with one end arranged at the side end of the slide plate 41 far from the first gear 43 and the other end connected to a push block 46. The bottom end of the push block 46 always abuts against the conversion device 100.

[0036] Even further, as Figure 2 、 Figure 6 and Figure 7 shown, the above-mentioned vertical moving device 5 includes a second gear 51, a pulley 52, a screw rod 53 and a driving plate 54; wherein two support blocks are arranged at the top of one end of the support plate 2. A rotating bearing is rotatably installed between the two support blocks, and a second gear 51 and a pulley 52 are fixedly sleeved on the rotating bearing. Among them, the pulley 52 is located at the end far from the horizontal moving device 4, and the pulley 52 is fixedly connected to the second gear 51. A driving plate 54 is arranged at one end of the third chute of the above-mentioned support plate 2. A screw rod 53 is installed on the driving plate 54, and the screw rod 53 passes through the middle of the rotating bearing and meshes with the rotating bearing. By moving the screw rod 53, the second gear 51 and the pulley 52 are driven to rotate synchronously. At the same time, a small hole for the conical rubber block 44 to enter is arranged on the driving plate 54 to facilitate the stable application of thrust.

[0037] Further, as shown in Figure 2 As shown, a clamping plate 71 is provided at the output end of the first elastic telescopic rod 7. The clamping plate 71 is at the same height as the second gear 51 and can collide with the second gear 51 to engage the rotation of the second gear 51. The first elastic telescopic rod 7 always has a driving force to drive the clamping plate 71 to move towards the second gear 51 during the specific movement process.

[0038] Further, as shown in Figure 2 As shown, the above-mentioned telescopic device 8 includes an electric telescopic rod 81, a protrusion 82 and an inclined rod 83. The electric telescopic rod 81 horizontally penetrates through the second mounting plate on the sliding plate 41 and is connected to an output end of the motor 42. The output end of the electric telescopic rod 81 is connected to the inclined rod 83. A detection probe 9 is provided at the top of the inclined rod 83. Further, the protrusion 82 is nested on the cylindrical surface of the output end of the electric telescopic rod 81 through a rotating bearing. The protrusion 82 has a certain weight itself, which makes the protrusion 82 always maintain a vertical state during the rotation of the electric telescopic rod 81. The protrusion 82 can move between the clamping plate 71 and the rack 3 during the specific movement process, and under the drive of the electric telescopic rod 81, it can push the clamping plate 71 to disengage the second gear 51 from the clamping of the clamping plate 71, and can also reversely squeeze the push block 46 to move the moving long plate 105 towards the first gear 43. Further, the inclined rod 83 is inclined compared to the electric telescopic rod 81, which can not only further expand the detection range of the detection probe 9 but also change the inclination angle of the detection probe 9.

[0039] Further, as shown in Figure 3 and Figure 4 As shown, the above-mentioned conversion device 100 includes a flat plate 101, a positioning block 102, a second elastic telescopic rod 103, a tapered block 104 and a moving long plate 105.

A fourth chute is provided in the middle of the flat plate 101. A positioning block 102 is vertically arranged inside the fourth chute. The positioning block 102 can horizontally move in the fourth chute of the flat plate 101. Further, as shown in Figure 5 As shown, a second elastic telescopic rod 103 is installed on the flat plate 101. The second elastic telescopic rod 103 is horizontally arranged, and the other end of the second elastic telescopic rod 103 is connected to the positioning block 102. The second elastic telescopic rod 103 always has a driving force to drive the positioning block 102 to move towards the moving long plate 105. A tapered block 104 is provided at the top of the positioning block 102. An inclined surface is provided on the top surface of the tapered block 104. The inclined surface of the tapered block 104 is always in contact with the rack 3 above it, playing a role in supporting and positioning the rack 3. One end of the positioning block 102 away from the second elastic telescopic rod 103 is connected to a horizontal connecting block, and the other end of the horizontal connecting block is connected to a moving long plate 105. The moving long plate 105 is vertically located on the side of the support plate 2 away from the positioning rack 3 and is always in close contact with the bottom end of the push block 46.

[0040] Working principle of the present invention:

[0041] In the specific detection process, the motor 42 drives the first gear 43 to move on the rack 3, which can adjust the horizontal position of the detection probe 9; when it is necessary to change the tilt angle of the detection probe 9 or the local vertical position, the electric telescopic rod 81 contracts, and then drives the protrusion 82 to squeeze the push block 46. The push block 46 squeezes the moving long plate 105 to move towards the second elastic telescopic rod 103, squeezing the second elastic telescopic rod 103 to move. The movement of the moving long plate 105 drives the positioning block 102 and the tapered block 104 to move towards the second elastic telescopic rod 103 together. The movement of the tapered block 104 drives the rack 3 to move downward and disengage from the first gear 43 (as Figure 5 shown); then the motor 42 drives the electric telescopic rod 81 to rotate, driving the inclined rod 83 to rotate to change the tilt angle of the detection probe 9 and the local vertical position; by changing the tilt angle of the detection probe 9, the detection probe 9 can better fit the curved surface of the detection tool, avoiding the problem that the detection surface of the tool is often not a plane, and accurate data cannot be obtained by single-direction detection;

[0042] When the detection probe 9 needs to be lifted, the motor 42 drives the first gear 43 to move on the rack 3 until it moves to a position where the tapered rubber block 44 is close to the small hole on the driving plate 54 (as Figure 6 shown). At this time, the protrusion 82 is located between the engaging plate 71 and the driving plate 54; the motor 42 drives the first gear 43 to continue moving on the rack 3 towards the second gear 51, pushing the front end of the tapered rubber block 44 into the small hole provided on the driving plate 54; then the electric telescopic rod 81 drives the protrusion 82 to push the engaging plate 71 to move it away from the second gear 51, and the second gear 51 disengages from the engagement with the engaging plate 71 (as Figure 7 shown); the motor 42 drives the first gear 43 to continue moving on the rack 3 towards the second gear 51, pushing the tapered rubber block 44 to move. Affected by the larger tapered bottom surface of the output end of the tapered rubber block 44, the tapered rubber block 44 drives the driving plate 54 to move to drive the screw rod 53 to move. The movement of the screw rod 53 drives the pulley 52 to rotate, and the pulley 52 rotates to wind the rope 6, causing the support plate 2 to move upward as a whole on the bracket 1; after the support plate 2 has moved upward, the electric telescopic rod 81 drives the protrusion 82 to disengage from the engaging plate 71, causing the engaging plate 71 to reset. Under the action of the first elastic telescopic rod 7, the second gear 51 is re-engaged by the engaging plate 71; the lifting operation of the detection probe 9 ends;

[0043] When the detection probe 9 needs to be lowered, at Figure 7In the state of , the electric telescopic rod 81 drives the protrusion 82 to disengage the second gear 51 from the engaging plate 71, and the motor 42 drives the first gear 43 to move in the opposite direction of the second gear 51 on the rack 3. Affected by the self-gravity of the support plate 2, the pulley 52 rotates to release the rope 6, the screw rod 53 moves in the reverse direction, and the driving plate 54 moves together with the conical rubber block 44, and the support plate 2 moves downward as a whole on the bracket 1; the front end of the conical rubber block 44 can enter the small hole on the driving plate 54, which increases the effective contact area between the conical rubber block 44 and the driving plate 54, and the conical rubber block 44 can better control the moving state of the driving plate 54.

[0044] The above has described an embodiment of the present invention in detail, but the content described is only a preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention shall still fall within the scope covered by the patent of the present invention.
