Description

Technical Field

[0002] Although my country's expressway construction started relatively late, it has developed rapidly overall. As of the end of 2019, the total mileage of highways nationwide reached 5.0125 million kilometers, of which 149,600 kilometers were expressways. This indicates that as my country's total highway mileage gradually increases, future expressways will move towards informationization, intelligence, and mechanization.

[0030] like Figure 5 、 6As shown, the mobile device 2 includes an upper mobile frame 201, a second stepper motor 202, a gear 203, a gear bar 204, two guide rails 205, a mobile platform 206, a power supply system mounting plate 207, and a lower mobile frame 208; the mobile device 2 is connected to the tail end of the truck 6 sideboard, the two guide rails 205 are fixedly connected to the middle of the bottom of the upper mobile frame 201 and the right side of the bottom of the lower mobile frame 208, the gear bar 204 is fixedly connected to the middle of the bottom of the lower mobile frame (208), the upper and lower ends of the mobile platform 206 are slidably connected to the upper mobile frame 201 and the lower mobile frame 208 respectively, the gear 203 is connected to the output end of the second stepper motor 202, the gear 203 is meshed with the gear bar 204 for transmission, and the power supply system mounting plate 207 is connected to the mobile platform 206.

However, the control system is not completely limited to this control logic. The company's technical personnel can make corresponding changes to the specific technical solutions based on this.

[0034] like Figure 5 As shown, the lighting warning system 5 includes a left lighting warning light 501 and a right lighting warning light 502. The left lighting warning light 501 and the right lighting warning light 502 are respectively connected to the left and right ends of the mobile device, and are used to provide road warnings and night lighting when the isolation cone automatic retraction device is working.

[0035] The placement process of the isolation cone: set the isolation cone to be placed diagonally on the left or right, the mobile platform 206 starts to reset, the second stepper motor 202 rotates and drives the gear 203, thereby causing the gear 203 to move on the gear bar 204, and further drives the mobile platform 206 to drag the power supply system installation plate 207 and the lifting device 1 to move to the right or left end of the mobile device 2 and trigger the limit sensor, and the mobile platform 206 is reset. Combined with different diagonal placement lengths and isolation cone placement spacing requirements, the system calculates the arc of each rotation of the stepper motor 109; then, the isolation cone is placed diagonally on the left or right, and the system starts the stepper motor 109 to rotate downward according to the input diagonal length and diagonal isolation cone spacing. The stepper motor 109 drives the synchronous wheel 112 to rotate, and the synchronous wheel 112 drives the active wheel 102 to rotate through the synchronous belt 113. The active wheel 102 drives the driven wheel 106 to do a circular motion through the belt 110, so that the manipulator 111 and the magnetic ring connector 105 are reset to the initial position of clamping the isolation cone under the rotation of the belt 110, at which time the stepper motor 109 stops rotating and the manipulator 111 opens; the operator places the isolation cone within the clamping range of the manipulator 111, and the manipulator 111 automatically closes when it senses that the isolation cone is within the clamping range, and at this time the stepper motor 109 is triggered to rotate downward again. After a series of transmissions, the manipulator 111 holding the isolation cone reaches the initial position of placing the isolation cone on the road surface, and triggers the cone release signal to control the manipulator 111 to release the isolation cone and trigger the moving device to rotate in an arc according to different isolation cone placement requirements, thereby completing the diagonal placement of one isolation cone, and the manipulator 111 rotates to the next work position through the belt 110, and repeats this cycle until the mobile platform 206 triggers the limit sensor at the leftmost or right end of the moving device 2, thereby completing the automatic left or right diagonal placement of the isolation cone.

[0036] The folding process of the isolation cone: When folding the isolation cone, the manipulator 111 is rotated and reset to the initial position of the folded isolation cone through the belt 110 and the manipulator 111 is opened. The car backs up, and the moving device 2 moves the lifting device 1 to the range of the manipulator 111 clamping the isolation cone. When the manipulator 111 senses that the isolation cone is within the clamping range, it automatically closes and clamps the isolation cone. The system triggers the stepper motor 109 to rotate upward, and brings the manipulator 111 clamping the isolation cone to the corresponding position on the truck 6 through the belt 110, triggering the manipulator 111 to release the isolation cone. The operator removes the isolation cone from the manipulator 111, thereby completing the folding of one isolation cone. The manipulator 111 rotates to the next work position through the belt 110, and the cycle continues.

[0037] The present invention adopts PLC and combines it with mechanical vision to control the mechanical structure to meet the designed action, realize the automatic placement and folding operation of isolation cones at any position on the highway, and can complete the diagonal placement and folding operation of isolation cones, which can meet the placement of any distance and any isolation cones. The centralized control and distributed management methods are adopted to better cooperate with the mechanical structure and electric control. The automatic isolation cone retraction and extension equipment also includes a video recording system to further ensure the safety of the work and smooth communication. The present invention provides an automatic isolation cone retraction and extension equipment, which can automatically place and fold isolation cones of any material during the maintenance and road closure process of the highway. It can be quickly and conveniently installed on a truck to realize the placement and folding of isolation cones.
