[0033] Other objects and advantages of the present invention will become clear by explaining the preferred embodiments of the present application below.

[0034] like Figures 1 to 16 As shown, an automatic cutting device for precast concrete components includes: a frame 1, on which a rotatable cutting blade 2 is mounted, the central axis of rotation of the cutting blade 2 being horizontally arranged, and the cutting blade 2 being used to cut the blank of the precast concrete component to the required length. The configuration of the cutting blade 2 is prior art and will not be described in detail here.

[0035] The frame 1 has four traveling units 3 on its lower side for supporting it, located near the four corners of the frame. Each traveling unit 3 has a first state where it moves the frame 1 in a forward-backward direction, and a second state where it moves the frame 1 in a left-right direction. During the cutting of a concrete blank, after one cut is completed, the traveling unit 3 moves the equipment to the next cutting position. After completing the cutting of one concrete blank, the traveling unit 3 is adjusted to the second state, allowing the equipment to cross over the next concrete blank and move onto the top of it.

[0036] The walking unit 3 has a wheel body 33 composed of a first walking wheel 6 and a second walking wheel 7; the first walking wheel 6 and the second walking wheel 7 are coaxially arranged; the steering drive unit 4 is used to drive the walking unit to switch between a first state and a second state; wherein, in the first state, the outer contours of the first walking wheel 6 and the second walking wheel 7 form a complete circular structure, making the device suitable for walking on flat ground; in the second state, the outer contours of the first walking wheel 6 and the second walking wheel 7 form a plurality of evenly arranged notches, allowing the device to cross over a cut precast concrete component blank to an adjacent blank.

[0037] In one possible implementation, such as Figure 2 As shown, the steering drive unit 4 includes a steering drive element 401, a steering drive wheel 402, a steering drive belt 403, and a steering driven wheel 404; the steering drive element 401 is fixedly connected to the frame 1, the output end of the steering drive element 401 is fixedly connected to the steering drive wheel 402, and the steering drive wheel 402 and the steering driven wheel 404 are connected by the steering drive belt 403; the steering driven wheel 404 is connected to the walking unit 3 and is used to drive the walking unit 3 to switch the walking direction.

[0038] In this embodiment, a steering drive unit 4 is provided on the left and right sides of the frame 1, respectively, to drive the walking units 3 on both sides to switch the direction of travel.

[0039] The steering drive unit 4 can also be implemented using gears, pulleys, or other equivalent mechanical transmission mechanisms.

[0040] In one possible implementation, the walking unit 3 includes a column 31 and a steering sleeve 32. The column 31 is fixedly connected to the frame 1 and is vertically arranged. The steering sleeve 32 is rotatably connected to the column 31. The outer contour of the column 31 is provided with a shoulder 311, and the upper end of the steering sleeve 32 abuts against the shoulder 311 to support the frame 1.

[0041] The steering driven wheel 404 is fixedly connected to the steering sleeve 32 and is used to drive the steering sleeve 32 to rotate around the column 31 to realize the steering of the walking unit 3.

[0042] In one possible implementation, the lower end of the steering sleeve 32 is provided with an axle 322, which extends in the horizontal direction; one end of the axle 322 is fixedly connected to the steering sleeve 32; and the first traveling wheel 6 is rotatably connected to the axle 322.

[0043] In one possible implementation, a walking drive unit 5 is also included; the walking drive unit 5 includes a walking drive element 501, a walking drive gear 502, a walking driven gear 503, and a transmission sleeve 504; the walking driven gear 503 is fixedly connected to the first walking wheel 6 through the transmission sleeve 504; a support frame 321 is fixed on the steering sleeve 32, and the walking drive element 501 is fixedly connected to the support frame 321; the output end of the walking drive element 501 is fixedly connected to the walking drive gear 502, and the walking drive gear 502 meshes with the walking driven gear 503 to drive the first walking wheel 6 to rotate around the wheel axle 322.

[0044] In one possible implementation, the first walking wheel 6 is connected to the second walking wheel 7 via a first one-way transmission assembly 91 and a shift fork 10, and is used to drive the second walking wheel 7 to rotate synchronously with the first walking wheel 6 when walking.

[0045] In one possible implementation, the first traveling wheel 6 includes a first wheel disc 61 and a plurality of first arc-shaped support portions 63 evenly arranged on the outer side of the first wheel disc 61; the first wheel disc 61 is provided with a first inner hole portion 62; the first one-way transmission assembly 91 includes a transmission plate 901, four locking pins 902 and four elastic elements 903; the outer contour of the transmission plate 901 is provided with four wedge-shaped surfaces and countersunk holes 9015 corresponding to the wedge-shaped surfaces.

[0046] The four wedge-shaped surfaces include a first wedge-shaped surface 9011, a second wedge-shaped surface 9012, a third wedge-shaped surface 9013, and a fourth wedge-shaped surface 9014 sequentially arranged on the outer contour of the transmission plate 901; the four locking pins 902 include a first locking pin 9021 corresponding to the first wedge-shaped surface 9011, a second locking pin 9022 corresponding to the second wedge-shaped surface 9012, a third locking pin 9023 corresponding to the third wedge-shaped surface 9013, and a fourth locking pin 9014 corresponding to the fourth wedge-shaped surface 9014. Four locking pins 9024; the radially outer ends of the first wedge-shaped surface 9011 and the third wedge-shaped surface 9013 are located on the counterclockwise side of their radially inner ends; the radially outer ends of the second wedge-shaped surface 9012 and the fourth wedge-shaped surface 9014 are located on the clockwise side of their radially inner ends; one end of the elastic element 903 is connected to the countersunk hole portion 9015, and the other end is connected to the corresponding locking pin 902, for providing an elastic force to slide the locking pin 902 toward the side where the corresponding wedge-shaped surface is located.

[0047] The shift fork 10 includes a sleeve portion 101 and a first arc-shaped actuating portion 102 and a second arc-shaped actuating portion 103 symmetrically disposed on the outer contour of the sleeve portion 101. The radially outer end of the first arc-shaped actuating portion 102 is located between the first wedge surface 9011 and the second wedge surface 9012, and extends to the clockwise and counterclockwise sides respectively. The radially outer end of the second arc-shaped actuating portion 103 is located between the third wedge surface 9013 and the fourth wedge surface 9014, and extends to the clockwise and counterclockwise sides respectively. The second traveling wheel 7 is fixedly connected to the shift fork 10, for example, by means of screws. The first wheel 61 sequentially drives the second traveling wheel 7 to rotate through the locking pin 902 in the first one-way transmission assembly 91, the transmission plate 901, and the shift fork 10.

[0048] The principle is as follows: When the first traveling wheel 6 rotates clockwise, the first wheel disc 61 rotates clockwise, and the first locking pin 9021 wedges into the gap between the first wedge surface 9011 and the first inner hole 62 of the first wheel disc 61. The third locking pin 9023 wedges into the gap between the third wedge surface 9013 and the first inner hole 62. Through the transmission disc 84, the first arc-shaped actuating part 102 and the second arc-shaped actuating part 103 of the shift fork 10 rotate, further driving the second traveling wheel 7 to rotate. At this time, the second locking pin 9022 and the fourth locking pin 9024 move away from the corresponding wedge surfaces. When the first traveling wheel 6 rotates counterclockwise, the second locking pin 9022 and the fourth locking pin 9024 play a transmission role, while the first locking pin 9021 and the third locking pin 9023 move away from the corresponding wedge surfaces.

[0049] However, when the shift fork 10 moves actively, with Figure 9 and Figure 14 Taking the clockwise direction as an example, the first arc-shaped actuating part 102 of the shift fork 10 pushes the first locking pin 9021 to move clockwise, compressing the elastic element 903, thereby preventing the first locking pin 9021 from wedging into the gap between the first wedge surface 9011 and the first inner hole 62. The third locking pin 9023 is in the same state as the first locking pin 9021. At this time, the second locking pin 9022 is in a state away from the second wedge surface 9012, and the fourth locking pin 9024 is in a state away from the fourth wedge surface 9014.

[0050] Therefore, the first one-way transmission assembly 91 can only perform one-way transmission from the outer first inner hole portion 62 to the inner shift fork 10, while the shift fork 10 cannot transmit to the first inner hole portion 62.

[0051] The second one-way transmission assembly 92 has the same structure as the first one-way transmission assembly 91 and is symmetrically arranged on both sides of the shift fork 10. In the second one-way transmission assembly 92, the transmission disc 84 sequentially drives the second traveling wheel 7 to rotate through the locking pin 902, the transmission plate 901, and the shift fork 10 in the second one-way transmission assembly 92.

[0052] In one possible implementation, an adjustment unit 8 is also included, which includes a fixed bevel gear 81, a movable bevel gear 82, a drive shaft 83, and a drive disk 84; the fixed bevel gear 81 is fixed to the lower end of the column 31; the movable bevel gear 82 meshes with the fixed bevel gear 81; the drive shaft 83 passes through the inner hole of the axle 322; one end of the drive shaft 83 is fixedly connected to the movable bevel gear 82, and the other end of the drive shaft 83 is fixedly connected to the drive disk 84; the drive disk 84 is connected to the second traveling wheel 7 via a second one-way transmission assembly 92.

[0053] The principle is as follows: when the steering drive unit 4 drives the walking unit 3 to turn, the steering driven wheel 404 drives the steering sleeve 32 to rotate, and the steering sleeve 32 further drives the wheel axle 322 to rotate around the steering sleeve 32. The transmission shaft 83 of the adjustment unit 8 is located in the inner hole of the wheel axle 322 and rotates around the steering sleeve 32 together with the wheel axle 322. The fixed bevel gear 81 is fixedly connected to the column 31. When the column 31 is fixed, the fixed bevel gear 81 remains stationary. The movable bevel gear 82 rotates around the column 31 and the steering sleeve 32 together with the transmission shaft 83. The movable bevel gear 82 and the fixed bevel gear 81 remain meshed. While the movable bevel gear 82 performs planetary motion around the fixed bevel gear 81, the movable bevel gear 82 drives the transmission shaft 83 and the transmission disc 84 to rotate around the wheel axle 322. The second inner hole 841 of the transmission disk 84 further drives the shift fork 10 and the second traveling wheel 7 to rotate through the second one-way transmission assembly 92. The second traveling wheel 7 rotates relative to the first traveling wheel 6, and the outer contours of the first traveling wheel 6 and the second traveling wheel 7 form a plurality of evenly arranged notch structures.

[0054] The above describes the process of walking unit 3 switching from the first state to the second state. The process of walking unit 3 switching back from the second state to the first state is the reverse of the above process and will not be described again.

[0055] In one possible implementation, the gear ratio of the fixed bevel gear 81 and the movable bevel gear 82 is 1:2. The first traveling wheel 6 includes four first arc-shaped support portions 63, each occupying 45° in the circumferential direction. The second traveling wheel 7 includes a support ring 71 and four second arc-shaped support portions 72 evenly distributed around the support ring 71, each occupying 45° in the circumferential direction. During the state switching process, the movable bevel gear 82 rotates 90° around the fixed bevel gear 81. The aforementioned gear ratio allows the second traveling wheel 7 to rotate 45° relative to the first traveling wheel 6. Thus, in the first state, the first traveling wheel 6 and the second traveling wheel 7 form a complete circular outer contour. In the second state, the first traveling wheel 6 and the second traveling wheel 7 overlap in the circumferential direction, forming four notch structures 34.

[0056] In addition, multiple lifting hydraulic cylinders can be installed on the frame 1. The cylinder barrel of the lifting hydraulic cylinder is fixedly connected to the frame 1, and the piston rod of the lifting hydraulic cylinder extends downward to the lower side of the frame 1. This is used to lift the frame 1 during the state switching process, so that each walking unit 3 is separated from the ground, which is beneficial for the state switching of the walking unit 3.

[0057] The apparatus of this application has been described in detail with reference to the preferred technical solutions. However, it should be noted that, without departing from the spirit of this application, those skilled in the art can make any modifications, alterations, and variations based on the above disclosure. This application includes the above-described specific embodiments and any equivalent forms thereof.
