Description

Technical Field

[0001] This invention relates to the field of pipe pile mold production, and specifically to a positioning device and method for pipe pile molds. Background Technology

[0002] Pipe piles are prestressed concrete pipe piles, and pipe pile molds are the molds required for pipe pile production. See the appendix for the structure of pipe pile molds. Figure 1 and attached Figure 2 As shown, the pipe pile mold 1 mainly consists of two semi-circular cross-section semi-cover molds 11. The two semi-cover molds 11 are spliced ​​together to form a tube. Connecting blocks 12 are provided on both sides of the semi-cover molds 11. Bolts 14 are used to fix the two semi-cover molds 11 through the connecting blocks 12, thereby fixing the two semi-cover molds 11 together. One side of the connecting block 12 is used to cooperate with the other connecting block 12, and the other side plane can be called the mold closing positioning surface 13. When installing with bolts 14, the head of the bolt 14 abuts against the mold closing positioning surface 13. When the pipe pile mold 1 is transported on the chain conveyor line, it has running wheels 15. The running wheels 15 are sleeved on the two semi-cover molds 11. The running wheels and the chain conveyor line cooperate to play a transportation role.

[0003] Currently, the automation level of pipe pile production in workshops is low. Complex production processes such as stripping the edge of pipe pile molds and inserting the reinforcing bars into the molds are mostly completed manually. This results in problems such as high labor intensity, poor working environment, and high worker demands for on-site personnel. It is also difficult to accurately position the pipe pile molds during production, which affects both the processing quality of the pipe pile molds and the level of automation in the workshop, thus impacting production efficiency. Therefore, in order to create conditions for the automated production of pipe piles, how to accurately position the pipe pile molds on the conveyor line is an urgent problem to be solved. Summary of the Invention

[0004] In view of the shortcomings of the prior art described above, the technical problem to be solved by the present invention is to provide a positioning device and method for pipe pile molds, which can perform axial and circumferential positioning of pipe pile molds on the production line, with good positioning accuracy and flexible and reliable use.

[0005] To achieve the above objectives, the present invention provides a positioning device for a pipe pile mold, comprising a lifting support mechanism and a leveling mechanism. The lifting support mechanism includes a base, a lifting component, a top plate, a support wheel assembly, and a radial positioning component. The lifting component is mounted on the base, and the top plate is mounted on the lifting support mechanism. The support wheel assembly and the radial positioning component are both mounted on the top plate. The lifting component drives the top plate to move up and down relative to the base. The support wheel assembly includes multiple spaced and parallel support wheels. The radial positioning component includes multiple positioning clamps and a positioning drive unit for driving the positioning clamps to move. The positioning clamps are used to abut against the two end faces of the running wheels on the pipe pile mold. The leveling mechanism includes a base, a lifting component, a top frame, and a leveling support component. The lifting component is mounted on the base, and the top frame is mounted on the lifting component. The lifting component drives the top frame to move up and down perpendicular to the base. The leveling support component includes two support seats symmetrically mounted on the top frame, and the two support seats are used to support the pipe pile mold on the mold closing positioning surfaces on both sides, so that the pipe pile mold is in a horizontal state.

[0006] Furthermore, the support wheel assembly in the lifting support mechanism also includes return springs disposed at the front and rear ends of the support wheel.

[0007] Furthermore, the radial positioning component in the lifting support mechanism includes at least two positioning clamps, and the positioning drive unit can drive the two positioning clamps to move closer together or separate in the direction of the support wheel axis.

[0008] Furthermore, the positioning drive unit in the lifting support mechanism includes two clamping cylinders, and the piston rods of the two clamping cylinders are respectively connected to two positioning clamping blocks.

[0009] Furthermore, a lifting guide structure is provided between the top plate and the base.

[0010] Furthermore, the base of the lifting support mechanism includes a base plate, a frame mounted on the base plate, and a horizontal adjustment structure disposed between the base plate and the frame. The horizontal adjustment structure is used to adjust the horizontal position of the frame on the base plate, and the lifting assembly is mounted on the frame.

[0011] Furthermore, the horizontal adjustment structure includes a plurality of adjusting screws screwed at different positions around the frame, with the lower ends of the adjusting screws abutting against the base plate.

[0012] Furthermore, the support seat in the leveling mechanism is provided with a first support surface parallel to the base, and the first support surface is used to support the mold closing and positioning surface of the pipe pile mold.

[0013] Furthermore, the top frame is also provided with a leveling working surface parallel to the base, and the leveling support assembly also includes an adjustment drive mechanism. The support seat is installed on the leveling working surface and can move on the leveling working surface. The adjustment drive mechanism can drive the support seat to move closer or further apart, and can lock the position of the support seat.

[0014] The present invention also provides a positioning method for a pipe pile mold using the above-mentioned positioning device, for positioning a pipe pile mold on a conveyor line, wherein the pipe pile mold has running wheels and a mold closing positioning surface, and includes the following steps:

[0015] Axial positioning of the pipe pile mold: The lifting support mechanism is activated, the lifting component raises the top plate, and the support wheel set supports the underside of the running wheel of the pipe pile mold; then the radial positioning component works, the positioning drive unit drives the positioning clamping block to abut against the two end faces of the running wheel, and axially positions the pipe pile mold.

[0016] Pipe pile mold horizontal positioning calibration: When the leveling mechanism is activated, the lifting component raises the top frame. The support seat on one side of the leveling support component first contacts the downward-facing mold closing positioning surface of the pipe pile mold, causing the pipe pile mold to rotate circumferentially on the support wheel until the downward-facing mold closing positioning surface on the other side also contacts the support seat on the other side, thus completing the horizontal positioning calibration of the pipe pile mold.

[0017] As described above, the positioning device and method of the present invention have the following beneficial effects:

[0018] By setting up a lifting support mechanism and a leveling mechanism, the pipe pile mold is supported and axially positioned by the lifting support mechanism, and the pipe pile mold can rotate circumferentially. Then, the leveling mechanism is used to calibrate the horizontal positioning of the pipe pile mold. This effectively achieves axial and circumferential positioning and leveling of the pipe pile mold on the conveyor line, solving the need for precise positioning of pipe pile molds in automated factory production. It provides a guarantee for the implementation of projects such as removing edge threads from the pipe mold and inserting cage reinforcement into the mold. Moreover, it is flexible and convenient to use and can be adapted to the working needs of pipe pile molds with different radius sizes. Attached Figure Description

[0079] See Figures 1 to 9 This invention provides a positioning device for a pipe pile mold 1, which can be installed on the chain conveyor line of the pipe pile mold 1 to position the pipe pile mold 1. The positioning device of this invention includes a lifting support mechanism and a leveling mechanism. The lifting support mechanism includes a base 6, a lifting assembly, a top plate 8, a support wheel set 9, and a radial positioning assembly 10. The lifting assembly is mounted on the base 6, the top plate 8 is mounted on the lifting support mechanism, and the support wheel set 9 and the radial positioning assembly 10 are both mounted on the top plate 8. The lifting assembly drives the top plate 8 to move up and down relative to the base 6. The support wheel set 9 includes multiple spaced and parallel support wheels 91. The radial positioning assembly 10 includes multiple positioning clamps 101 and a positioning drive unit that drives the positioning clamps 101 to move. The positioning clamp 101 is used to abut against the two ends of the running wheel 15 on the pipe pile mold 1 to position the pipe pile mold 1 axially; the leveling mechanism includes a base 2, a lifting assembly 3, a top frame 4, and a leveling support assembly 5. The lifting assembly 3 is set on the base 2, and the top frame 4 is set on the lifting assembly 3. The lifting assembly 3 drives the top frame 4 to make a lifting movement perpendicular to the base 2. The leveling support assembly 5 includes two support seats 51 symmetrically set on the top frame 4. The two support seats 51 are used to support the mold closing positioning surface 13 on both sides of the pipe pile mold 1 respectively so that the pipe pile mold 1 is in a horizontal state.

[0080] During operation, the positioning device of this invention is used to accurately position the pipe pile mold 1 on the chain conveyor line. The pipe pile mold 1 is conveyed in a flat position on the conveyor line. The positioning method includes axial positioning and horizontal positioning calibration of the pipe pile mold 1. Axial positioning of the pipe pile mold 1: The lifting support mechanism is activated, the lifting component raises the top plate 8, and the support wheel group 9 supports the underside of the running wheel 15 of the pipe pile mold 1. Then, the radial positioning component 10 is activated, and the positioning drive unit drives the positioning clamp 101 to abut against the two end faces of the running wheel 15, thereby positioning the pipe pile mold 1 axially. Positioning is correct; Horizontal positioning calibration of pipe pile mold 1: The leveling mechanism operates, the lifting component 3 lifts the top frame 4, and the support seat 51 on one side of the leveling support component 5 first contacts the downward-facing mold closing positioning surface 13 on one side of the pipe pile mold 1, causing the pipe pile mold 1 to rotate circumferentially on the support wheel 91 until the downward-facing mold closing positioning surface 13 on the other side also contacts the support seat 51 on the other side. The two support seats 51 are at the same height during operation, so that the mold closing positioning surfaces 13 on both sides of the pipe pile mold 1 reach a horizontal state, completing the horizontal positioning calibration of the pipe pile mold 1.

[0081] The positioning device of the present invention can position the pipe pile mold 1 in the axial and circumferential directions, complete the horizontal calibration, and achieve complete positioning of the posture of the pipe pile mold 1, thus providing a guarantee for the implementation of subsequent projects such as removing edge wires and inserting cage reinforcement.

[0082] See Figures 3 to 9 The positioning device of the present invention will be further described below with reference to a specific embodiment:

[0083] In this embodiment, see Figure 2 and Figure 9 With the circumferential direction of the support wheel 91 as the Y-axis, the linear lifting motion of the top plate 8 relative to the base 6 is in the Z-axis direction. The two support wheels 91 are arranged in the X-axis, and the plane containing their axes is perpendicular to the Z-axis, meaning the two support wheels 91 are at the same height, with the X, Y, and Z axes perpendicular to each other. When the support is below the running wheel 15, the supporting force of the two support wheels 91 on the running wheel 15 is symmetrical, resulting in more stable support. Of course, in other embodiments, the two support wheels 91 are not at the same height. The top plate 8 serves as the installation reference for the support wheel assembly 9 and the radial positioning component 10, etc. Its upper end is flat, which can be used to assist in adjusting the lifting support mechanism to maintain a horizontal state during position adjustment. During operation, the top plate 8 remains horizontal. Of course, there may be two or more support wheels 91.

[0084] In this embodiment, see Figure 2 and Figure 9As a preferred design, the support wheel assembly 9 in the lifting support mechanism also includes return springs 93 located at both ends of the support wheel 91. The support wheel 91 is mounted in the wheel seat 92, and the return springs 93 are located between the wheel seat 92 and the end face of the support wheel 91. When the running wheel 15 is clamped by the radial positioning assembly 10, the running wheel 15 may experience a small axial displacement on the support wheel 91. The return springs 93 allow the support wheel 91 to move axially with the running wheel 15, reducing wear between the support wheel 91 and the running wheel 15. After the running wheel 15 is disengaged, the support wheel 91 can return to its original position under the action of the return springs 93.

[0085] In this embodiment, see Figure 2 and Figure 9 As a preferred design, the lifting support mechanism has two positioning clamps 101 arranged along the Y-direction. The positioning drive unit can drive the two positioning clamps 101 to move closer together or separate along the axis of the support wheel 91. When they move closer together, the two positioning clamps 101 abut against the two end faces of the running wheel 15, respectively, restricting the axial position of the running wheel 15 and the pipe pile mold 1, thus achieving axial positioning. When they separate, they move away from the two end faces of the running wheel 15, releasing the axial positioning. Preferably, the two positioning clamps 101 are kept facing each other, that is, they are located on a straight line in the Y-direction, which provides a better clamping and positioning effect on the running wheel 15. Preferably, the two positioning clamps 101 are located between the two support wheels 91, but they can also be located on the outside of the two support wheels 91. Of course, in other embodiments, the number of positioning clamps 101 can be increased.

[0086] In this embodiment, see Figure 2 and Figure 9 As a preferred design, the positioning drive unit in the lifting support mechanism includes two clamping cylinders 102, and the piston rods of the two clamping cylinders 102 are respectively connected to two positioning clamping blocks 101. The piston rods of the clamping cylinders 102 move along the Y-axis, and the extension and retraction of the piston rods drives the positioning clamping blocks 101 to move linearly along the Y-axis. The clamping cylinders 102 can be electric cylinders, pneumatic cylinders, or hydraulic cylinders. Of course, in other embodiments, the positioning drive unit can also adopt other suitable drive structures.

[0087] In this embodiment, see Figure 2 and Figure 9 As a preferred design, a lifting guide structure is provided between the top plate 8 and the base 6. The lifting guide structure includes a guide rod 64 fixed to the top plate 8 and a guide sleeve 65 fixed to the base 6. The guide rod 64 is located in the guide sleeve 65. The lifting guide structure ensures the stability of the top plate 8 during the lifting process and ensures that the raised top plate 8 is in a horizontal position.

[0088] In this embodiment, see Figure 2 and Figure 9The lifting assembly includes a lifting cylinder 7, with a lifting rod mounted in the base 6. The piston rod of the lifting cylinder is along the Z-axis and connected to the lower end of the top plate 8. The lifting cylinder 7 can be an electric cylinder, a pneumatic cylinder, or a hydraulic cylinder. The extension and retraction of the lifting cylinder 7 drives the top plate 8 to move stably in a linear motion along the Z-axis. Of course, in other embodiments, the lifting assembly can also employ other suitable mechanisms.

[0089] In this embodiment, see Figure 2 and Figure 9 As a preferred design, the base 6 of the lifting support mechanism includes a base plate 61, a frame 62 mounted on the base plate 61, and a horizontal adjustment structure disposed between the base plate 61 and the frame 62. The horizontal adjustment structure is used to adjust the horizontal position of the frame 62 on the base plate 61, and the lifting cylinder 7 is mounted on the frame 62. The horizontal adjustment structure includes multiple adjusting screws 63 screwed to different positions around the frame 62. The adjusting screws can be directly screwed into the frame 62, or screwed into nuts fixed to the frame 62. The lower end of the adjusting screw 63 rests against the base plate 61, and preferably, a recess is provided on the base plate 61 for limiting the position of the adjusting screw 63. When placing the lifting support mechanism, the base plate 61 is placed on the corresponding area of ​​the ground. Since the ground may be uneven, the adjusting screws 63 at different positions can be used to ensure the horizontal position of the frame 62, thereby ensuring that the frame 62 and the top plate 8 are horizontal during operation. Of course, in other embodiments, the horizontal adjustment structure may also employ other suitable structures.

[0090] In this embodiment, see Figure 4 and Figure 7 As a preferred design, in the leveling mechanism, the support base 51 is provided with a first support surface 511 parallel to the base 2. The first support surface 511 is used to support the mold closing positioning surface 13 of the pipe pile mold 1. Through the contact between the surfaces, the mold closing positioning surface 13 of the pipe pile mold 1 can be better supported and positioned, and the horizontal positioning calibration effect of the pipe pile mold 1 is better.

[0091] In this embodiment, see Figure 4 and Figure 7As a preferred design, in the leveling mechanism, the support base 51 is further provided with a second support surface 512 parallel to the leveling working surface 41, and the second support surface 512 and the first support surface 511 are located at different heights. Specifically, in this embodiment, the second support surface 512 is located outside the first support surface 511 and is higher than the first support surface 511. This method can adapt to the positioning and leveling of pipe pile molds 1 with different radii. Preferably, the upper end of the support base 51 has a detachable support head 513, and both the second support surface 512 and the first support surface 511 are provided on the support head 513. This allows for the replacement of the support head 513 to meet the needs of pipe pile molds 1 of different specifications.

[0092] In this embodiment, see Figure 4 and Figure 7 As a preferred design, in the leveling mechanism, the top frame 4 also has a leveling working surface 41 parallel to the base 2. The leveling support assembly 5 also includes an adjustment drive mechanism. The support seat 51 is installed on the leveling working surface 41 and can move on the leveling working surface 41, that is, its movement direction is parallel to the leveling working surface 41. The adjustment drive mechanism can drive the support seat 51 to move closer or further apart, and can lock the position of the support seat 51. Preferably, the support seat 51 is installed on the top frame 4 in a linear movement manner, and a linear guide mechanism is provided between the support seat 51 and the top frame 4. The linear guide mechanism includes a linear slide rail 44 installed on the top frame 4. With the movement direction of the support seat 51 as the left and right direction, the linear slide rail 44 extends in the left and right direction. The support seat 51 is installed on the linear slide rail 44 and can slide stably along the linear slide rail 44. In this embodiment, preferably, the adjustment drive mechanism includes two push cylinders 52, respectively connected to the outer sides of the two support seats 51, which can stably drive the support seats 51 to move linearly. The push cylinders 52 can be hydraulic cylinders, electric cylinders, or pneumatic cylinders. Of course, the adjustment drive mechanism can also use other suitable drive components. By using the adjustment drive mechanism to drive the two support seats 51 to move, the distance between the two support seats 51 can be flexibly adjusted, thereby meeting the needs of pipe pile molds 1 with different radii.

[0093] In this embodiment, see Figure 4 and Figure 6As a preferred design, the lifting assembly 3 includes a fork frame 31 and a lifting drive unit. The fork frame 31 includes a first fork 311 and a second fork 312. The middle parts of the first fork 311 and the second fork 312 are hinged by a middle hinge pin 313 to form an X shape. The lower end of the first fork 311 is hinged to a hinge seat 23 on the base 2 by a lower hinge pin 315, and its upper end is mounted on the top frame 4. The upper end can move linearly relative to the top frame 4, and the direction of movement is parallel to the base 2. The upper end of the second fork 312 is hinged to an upper hinge pin 43 on the top frame 4 by a hinge hole 314, and its lower end is mounted on the base 2 and can move linearly relative to the base 2, and the direction of movement is parallel to the base 2. The lifting drive unit includes a lifting drive cylinder 32, which can be a hydraulic cylinder, an electric cylinder, or a pneumatic cylinder. It is mounted on the base 2 and connected to the upper end of the second fork 312 to drive the lower end of the second fork 312 to move linearly. During operation, the extension and retraction of the lifting drive cylinder 32 drives the lower end of the second fork 312 to move linearly, thereby causing the fork frame 31 to close or open, and thus driving the top frame 4 to rise or fall. Of course, the lifting drive cylinder 32 can also be connected to the upper end of the first fork 311 to drive the upper and lower ends of the first fork 311 to move linearly. At the same time, the lifting drive unit can also adopt other existing suitable drive structures.

[0094] In this embodiment, see Figure 4 , Figure 5 , Figure 6 and Figure 7Furthermore, the top frame 4 is provided with an upper straight slide groove 42, the upper end of the first fork 311 is provided with an upper roller 316 located in the upper straight slide groove 42, the base 2 is provided with a lower straight slide groove 21, and the lower end of the second fork 312 is provided with a lower roller 317 located in the lower straight slide groove 21. The upper straight slide groove 42 and the lower straight slide groove 21 are parallel in length direction and are both parallel to the base 2 and the leveling working surface 41. During the lifting process, the upper end of the first fork 311 rolls in the upper straight slide groove 42 through the upper roller 316 to achieve linear movement, and the lower end of the second fork 312 rolls in the lower straight slide groove 21 through the lower roller 317 to achieve linear movement. In this way, the friction is small, the movement of the fork-shaped frame 31 is stable, and the top frame 4 can be lifted and lowered stably without deflection during the lifting process. The installation method of the upper end of the first fork 311 to the top frame 4 and the installation method of the lower end of the second fork 312 to the base 2 can also adopt other forms. For example, the upper end of the first fork 311 can be hinged to a sliding sleeve, which is sleeved on the sliding rod on the top frame 4. In this embodiment, the structures of the first fork 311 and the second fork 312 are similar, both adopting the form of combined rods, mainly consisting of two side fork plates and multiple connecting rods connecting the two side fork plates. This structure is more stable and can provide greater support force. Of course, the first fork 311 and the second fork 312 can also be formed by a single rod. Of course, in other embodiments, the lifting assembly 3 can also adopt other suitable structures and be driven by a vertical cylinder.

[0095] In this embodiment, see Figure 4 and Figure 5 As a preferred design, the base 2 is equipped with a leveling mechanism, which is used to adjust the horizontal state of the base 2 when it is placed. Specifically, the leveling mechanism includes multiple leveling components 22 arranged around the base 2. The leveling components 22 include anchor bolts 221 vertically screwed into the base 2 and support plates 22 fixed to the bottom of the anchor bolts 221. In use, the base 2 is placed in the working area by the support plates 22 of the leveling components 22 around it. Then, by adjusting the vertical position of the anchor bolts 221 in the corresponding leveling components 22, the base 2 is adjusted to be in a horizontal state, which makes it more flexible and adaptable.

[0096] In this invention, the lifting mechanism and the leveling mechanism can be separate structures or an integral structure. When setting up the positioning device to position the pipe pile mold 1, multiple lifting support mechanisms and leveling mechanisms can be set according to the length of the pipe pile mold 1, see [reference]. Figure 9 In this embodiment, two lifting support mechanisms and two leveling mechanisms are provided. One lifting support mechanism and one leveling mechanism form a group and work together. They are set at different positions of the pipe pile mold 1. Of course, the number and arrangement of the lifting support mechanism and the leveling mechanism can also be other.

[0097] The positioning device used in this embodiment facilitates the positioning of the pipe pile mold in the chain conveyor line, specifically including the following steps:

[0098] S1. Install both the lifting support mechanism and the leveling mechanism at the chain conveyor line, and position them below the pipe pile mold 1 on the chain conveyor line; adjust the positions of the lifting support mechanism and the leveling mechanism so that the axis of the support wheel 91 is along the axis of the pipe pile mold 1, and the two support wheels 91 are located below the running wheel 15 on the pipe pile mold 1. The symmetrical center line of the two support seats of the leveling mechanism is along the axis of the pipe pile mold 1, and the first support surface is in a horizontal state. At this time, the height of the first support surface 511 on the two support seats 51 is the same.

[0099] S2. After the pipe pile mold 1 is conveyed above the lifting support mechanism and the leveling mechanism on the chain conveyor line, it stops. The pipe pile mold 1 is located between the two support wheels 91 and between the two support seats. At this time, without any deviation, the axis of the pipe pile mold 1 is along the axis of the support wheel 91, which makes it convenient for the support wheel 91 to support the running wheel 15. At the same time, the axis of the pipe pile mold 1 will be perpendicular to the symmetrical center line of the two support seats and located between the two support seats.

[0100] S3. The pipe pile mold 1 is axially positioned, and the lifting support mechanism is activated. The lifting assembly raises the top plate 8, and the two support wheels 91 of the support wheel group 9 support the lower ends of the running wheels 15 of the pipe pile mold 1, raising the pipe pile mold 1 away from the chain conveyor line. Then, the radial positioning assembly 10 operates, and the positioning drive unit drives the two positioning clamps 101 to move closer together, respectively abutting against the front and rear end faces of the running wheels 15, thus axially positioning the pipe pile mold 1. Furthermore, the use of two support wheels 91 can support pipe pile molds 1 with different radius sizes.

[0101] S4. Horizontal positioning and calibration of pipe pile mold 1. The leveling mechanism operates, and the lifting assembly raises the top frame. (See below) Figure 8 The first support surface 511 of the support seat 51 on one side of the leveling support assembly first contacts the downward-facing mold closing positioning surface 13 of the pipe pile mold 1, causing the pipe pile mold 1 to rotate circumferentially on the support wheel 91 until the downward-facing mold closing positioning surface 13 on the other side also contacts and fits against the first support surface 511 on the other side, thus completing the horizontal alignment of the pipe pile mold 1. Since the pipe pile mold 1 is located on the two support wheels 91 of the lifting support mechanism at this time, the pipe pile mold 1 can rotate smoothly on the two support wheels 91, and its axial position can also be guaranteed during the rotation.

[0102] After axial and circumferential positioning is completed, other equipment on the pipe pile mold 1 production line can automatically operate the pipe pile mold 1. After the operation is completed, the top frame 4 and the leveling support assembly 5 on it in the leveling mechanism descend and detach from the pipe pile mold 1. Then, the radial positioning assembly 10 in the lifting support mechanism releases the running wheel 15, and finally drives the top plate 8 to descend, lowering the pipe pile mold 1 onto the chain conveyor line.

[0103] The positioning device and method for the pipe pile mold of the present invention have the following technical effects:

[0104] It can effectively achieve axial and circumferential positioning and leveling of the pipe pile mold 1 on the conveyor line, solve the need for precise positioning of the pipe pile mold 1 in the automated production of the factory, provide a guarantee for the implementation of projects such as pipe mold edge stripping and cage reinforcement insertion, and is flexible and convenient to use, and can be adapted to the working needs of pipe pile mold 1 with different radius sizes.

[0105] In summary, this invention effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0106] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
