Detailed Embodiment
[0035] Embodiment 1
[0036] As Figures 1 to 3 shown, this embodiment provides a rapid shaping and shearing device for asphalt small beams, including a base 1, a bearing mechanism, two groups of horizontal limiting mechanisms, two groups of blocking members, several groups of vertical limiting mechanisms 9, and a cutting mechanism 4.
[0037] The bearing mechanism includes: a first transmission component 2 disposed on the upper surface of the base 1, a bearing member 3 drivingly arranged on the first transmission component 2, and a placing member 6 disposed on the bearing member 3.
[0038] The first transmission component 2 includes a guide rail 21, a first screw rod 22 rotatably disposed inside the guide rail 21, a first chute 23 opened on the upper surface of the guide rail 21 and communicating with the inside of the guide rail 21, first slide rails 24 disposed on both sides of the first chute 23, and a first motor 25 disposed at one end of the guide rail 21. The driving end of the first motor 25 is drivingly connected to the first screw rod 22. The bottom end of the bearing member 3 penetrates through the first chute 23 and is drivingly connected to the first screw rod 22, and both sides of the bottom end of the bearing member 3 are slidably connected to the first slide rails 24. The first chute 23, the first slide rails 24 and the bottom end of the bearing member 3 form a cooperation to drive the bearing member 3 to move along the length direction of the guide rail 21. The bottom end of the bearing member 3 is threadedly connected to the first screw rod 22 through a connecting block. The first motor 25 drives the first screw rod 22 to rotate, drives the bearing member 3 to move along the length direction of the first screw rod 22, and adjusts the relative position between the bearing member 3 and the cutting mechanism 4.
[0039] The placing member 6 is used for placing the asphalt block 5, and the placing member 6 is fixed on the bearing member 3 by bolts. The top surface of the placing member 6 is provided with multiple groups of criss-cross cutting grooves. In this embodiment, as Figure 2 shown, the cutting grooves are provided with multiple groups of first cutting grooves 61 and second cutting grooves 62. Multiple groups of mutually parallel first cutting grooves 61 are arranged at intervals along the length direction of the top surface of the placing member 6. The second cutting grooves 62 are perpendicular to the first cutting grooves 61. The spacing between adjacent first cutting grooves 61 and between adjacent second cutting grooves 62 is different. The first cutting grooves 61 and second cutting grooves 62 with different spacings form asphalt beam forming areas with different size specifications on the top surface of the placing member 6.
[0040] In this embodiment, the two groups of barrier members are respectively defined as a first baffle 7 and a second baffle 8, and the first baffle 7 and the second baffle 8 are correspondingly arranged on one side of the placing member 6. As Figure 2 shown, the first baffle 7 abuts against the right side of the asphalt block 5, and the second baffle 8 abuts against the rear end face of the asphalt block 5. The first baffle 7 and the second baffle 8 support and limit the asphalt block 5 from two different directions. The first cutting grooves 61 and the second cutting grooves 62 respectively extend through the corresponding first baffle 7 and second baffle 8 at both ends, so that there are grooves on the first baffle 7 and the second baffle 8. When the cutting mechanism 4 cuts along the first cutting groove 61 or the second cutting groove 62, it can be moved out from the groove, and thus the first baffle 7 or the second baffle 8 will not interfere with the cutting mechanism 4.
[0041] The horizontal limiting mechanism includes: a horizontal transmission component, and a limiting component provided at the output end of the horizontal transmission component. The horizontal transmission component can be implemented by linear transmission methods such as nut-screw transmission, gear-rack, etc. The limiting component includes: a mounting plate, multiple groups of connecting rods connected to the mounting plate in an array, and a blocking member provided on each connecting rod. The blocking member is set as a baffle plate. In this example, Figure 2 taking the direction in
[0042] as an example, the two horizontal limiting mechanisms are respectively defined as the first horizontal limiting mechanism and the second horizontal limiting mechanism with the same structure. The first horizontal limiting mechanism abuts against the left side of the asphalt block 5, so that the left and right sides of the asphalt block 5 are clamped and fixed between the first horizontal limiting mechanism and the first baffle plate 7. The second horizontal limiting mechanism abuts against the front end face of the asphalt block 5, so that the front and rear ends of the asphalt block 5 are clamped and fixed between the second horizontal limiting mechanism and the second baffle plate 8. The structures of the first horizontal limiting mechanism and the second horizontal limiting mechanism are specifically described as follows:
[0043] The first horizontal limiting mechanism includes a plurality of third baffle plates 101 arranged at intervals, a first mounting rod 102 provided on the side of the third baffle plate 101 away from the placing member 6, and a first connecting rod 103 provided between the first mounting rod 102 and the third baffle plate 101. The first horizontal limiting mechanism further includes second supporting members 111 symmetrically provided on the bearing member 3, a fourth screw rod 112 rotatably provided between the second supporting members 111, second slide rails 113 provided at both ends of the fourth screw rod 112, a second transmission nut 114 threadedly connected to the fourth screw rod 112, and a connecting arm 115 provided on the upper surface of the second transmission nut 114. The connecting arm 115 is connected to the first mounting rod 102. One end of the fourth screw rod 112 penetrates through the first supporting end on one side and extends to the outside of the second supporting member 111. A second knob 116 is provided on the fourth screw rod 112 outside the second supporting member 111. By rotating the second knob 116, the fourth screw rod 112 is driven to rotate. Since the second transmission nut 114 is threadedly connected to the fourth screw rod 112 and is slidably connected to the second slide rail 113, the second transmission nut 114 is driven to move along the fourth screw rod 112 in the direction close to the first baffle plate 7, and then the connecting arm 115 and the third baffle plate 101 are driven to approach the first baffle plate 7.
[0044] The cutting mechanism 4 includes a frame 41 disposed on the upper surface of the base 1, a second transmission assembly disposed at the bottom end of the frame 41, a lifting member 42 driven by the second transmission assembly at the output end, a rotating member 43 disposed at the output end of the lifting member 42, and a cutting wheel assembly 44 disposed at the output end of the rotating member 43. The lifting member 42 drives the cutting wheel assembly 44 to reciprocate up and down to approach or move away from the asphalt block 5. The lifting member 42 is implemented by an electric telescopic member or the like. The second transmission assembly drives the cutting wheel assembly 44 to move along the length direction of the first cutting groove 61 to cut the asphalt block 5. The rotating member 43 can be a motor to drive the cutting wheel assembly 44 to rotate by °. After the cutting wheel assembly 44 rotates by °, the first transmission assembly 2 drives the carrier 3 to move, so that the cutting wheel assembly 44 cuts the asphalt block 5 along the length direction of the second cutting groove 62. The cutting wheel assembly 44 is composed of a housing, a cutting wheel, a motor, etc. The cutting wheel is rotatably disposed in the housing and is driven by the motor to rotate. This is prior art and will not be described in detail here.
[0045] The second transmission assembly includes: first support members 45 symmetrically disposed at the bottom end of the frame 41, a second screw rod 46 rotatably disposed between the two first support members 45, a second motor 47 disposed on one of the first support members 45, a second sliding groove 48 opened on the frame 41 between the two first support members 45, and a first transmission nut 49 drivingly disposed on the second screw rod 46. The bottom end of the first transmission nut 49 is connected to the top end of the lifting member 42. A slider 410 slidably connected to the second sliding groove 48 is disposed at the top end of the first transmission nut 49. The second motor 47 drives the second screw rod 46 to rotate, driving the first transmission nut 49 to reciprocate along the second screw rod 46, driving the cutting wheel assembly 44 to reciprocate. The slider 410 cooperates with the second sliding groove 48 to make the movement of the first transmission nut 49 more stable.
[0046] The vertical limiting mechanism 9 includes a cross plate 91 disposed on the upper surface of the third baffle 101 or the first baffle 7, an annular sliding rail 92 disposed on the cross plate 91, a third screw rod 93 disposed in the annular sliding rail 92, a pressing block 94 disposed below the cross plate 91, and a first knob 95 rotatably disposed on the annular sliding rail 92. The bottom end of the third screw rod 93 penetrates through the cross plate 91 and is fixedly connected to the pressing block 94. The top end of the third screw rod 93 penetrates through the annular sliding rail 92 and is threadedly connected to the first knob 95. An annular sliding groove matching the annular sliding rail 92 is opened in the first knob 95 to make the first knob 95 rotate stably on the annular sliding rail 92. The third screw rod 93 is also threadedly connected to the cross plate 91. By rotating the first knob 95, the vertical position of the third screw rod 93 is driven to press the upper surface of the asphalt block 5 to prevent the asphalt block 5 from displacing vertically during cutting.
[0047] A length measuring tool 13 is arranged at an interval between the upper surface of the carrier 3 and the placing member 6, and a width measuring tool 14 is arranged at the bottom end on the measuring side of the length measuring tool 13. The length measuring tool 13 and the width measuring tool 14 are perpendicular to each other. The cut asphalt beam is directly detected at the length measuring tool 13 and the width measuring tool 14 to check whether the cut length and width are qualified, without the need for staff to carry it to the detection place for detection, and the practicability is better.
