The meshing of the motor 10 and the first gear 9 and the second gear 42 can achieve the purpose of changing the orientation of the prohibition card. The moving component includes a hydraulic cylinder 35. The hydraulic cylinder 35 is fixedly installed on the mounting seat 3, and one end of the hydraulic cylinder 35 is fixed with a rack. A cradle 34, one end of the mounting base 3 is provided with a cradle 39 connected by a shaft, one end of the cradle 39 is fixedly connected with two sets of third gears 40, the third gears 40 mesh with the rack frame 34, and the other end of the cradle 39 is hinged with a support block 38. When the hydraulic cylinder 35 is in the forward push state, one end of the hydraulic cylinder 35 stretches forward to drive the rack frame 34 to move forward. At this time, the third gear 40 meshing with the rack frame 34 rotates clockwise and drives the cradle 39 clockwise. Rotation, through the engagement of a cradle 39 rotatable relative to the mounting base 3 and the support block 38 provided at one end and the rack frame 34 with the third gear 40, the electric telescopic rod 41 can be moved to the horizontal while driving The prohibition card body 15 fixedly connected with the electric telescopic rod 41 is reset to give a prohibition warning.

When the hydraulic cylinder 35 retreats, one end of the hydraulic cylinder 35 moves backward to drive the rack frame 34 to move backward. At this time, the third gear 40 meshing with the rack frame 34 rotates counterclockwise, and at the same time drives the cradle 39 to rotate counterclockwise, which can realize electric power The retraction of the telescopic rod 41 drives the forbidden card body 15 fixedly connected with the electric telescopic rod 41 to retract simultaneously. One end of the support block 38 is provided with a dovetail block 37, and the dovetail block 37 is slidably clamped in the dovetail groove 18 opened at the bottom of the electric telescopic rod 41. Through the cooperation of a group of dovetail grooves 18 and the dovetail block 37, the cradle 39 can be moved clockwise.

The bottom of the lifting assembly is provided with a limiting assembly; when using the lifting assembly, hold the handle 13 and turn the sleeve 26 clockwise. Since the twist block 6 needs to slide in the helical twist groove 24, the telescopic column 25 will move upward at this time. When the torsion block 6 slides to the other end of the torsion groove 24, the lifting height reaches the maximum, and after the lifting request is completed, the position of the lifting assembly is locked by the limit assembly.

As shown in FIGS. 2 , 4 and 5 , the limiting assembly includes a ratchet 16 arranged at the bottom of the sleeve 26 and a base 5 . The base 5 is provided with an L-shaped slider 21 , and both sides of the L-shaped slider 21 are fixedly connected There is a set of T-shaped blocks 29, two sets of T-shaped grooves 33 are opened in the base 5, and the two sets of T-shaped blocks 29 are respectively slidably clamped in the two sets of T-shaped grooves 33. It can achieve the effect that the L-shaped slider 21 is not easily deflected when sliding in the base 5 .

One end of the L-shaped slider 21 is provided with a mounting hole 28, and a spring 20 is fixed in the mounting hole 28, so that the wedge block 27 can be automatically retracted when the lifting assembly lifts the mounting seat 3, and one end of the spring 20 is provided with a wedge block 27, The wedge-shaped block 27 is clamped on the ratchet wheel 16, and the wedge-shaped block 27 ensures that the ratchet wheel 16 cannot rotate counterclockwise. When the lifting assembly is used, the limit assembly must be used to fix the height of the lifting assembly; The sleeve 26 rotates clockwise, which drives the ratchet wheel 16 at the bottom to rotate clockwise. It can be known from the matching relationship between the ratchet wheel 16 and the wedge block 27 that the wedge block 27 will automatically retreat at this time.

When the telescopic column 25 needs to be retracted, the L-shaped slider 21 needs to be lifted upwards, so that the T-shaped blocks 29 on both sides of the L-shaped slider 21 slide up in the T-shaped groove 33 where they are located, and drive the wedge-shaped block 27 to disengage from the ratchet wheel. 16, the ratchet 16 and the sleeve 26 will rotate counterclockwise under the gravity of the upper part, and the telescopic column 25 and the upper mounting seat 3 will fall down until the telescopic column 25 returns to its original height before being lifted.

As shown in FIG. 4 and FIG. 5 , the limiter assembly further includes a connecting plate 23 . The connecting plate 23 is provided with a chute 22 . The existence of the chute 22 ensures that the connecting plate 23 drives the L-shaped slider 21 to rise. One end of the base 5 is provided with a support shaft 32, the support shaft 32 is slidably clamped in the chute 22, and one end of the connecting plate 23 is sleeved on the mounting shaft 31 on the L-shaped slider 21, and the connecting plate 23 The other end is provided with a pedal 2; the staff can step on the pedal 2 to realize the rise of the L-shaped slider 21, and press the pedal 2, at this time, the connecting plate 23 rotates counterclockwise, and at the same time the connecting plate 23 will move to the L-shaped along the chute 22. One side of the slider 21 slides a certain distance, and the counterclockwise rotation of the connecting plate 23 will drive the L-shaped slider 21 to rise.

As shown in FIG. 1 and FIG. 4 , the base 5 is provided with an installation cylinder 4 , the sleeve 26 is penetrated in the installation cylinder 4 , four sets of installation ribs 1 are fixedly connected on both sides of the base 5 , and the installation ribs 1 are provided with holes. The base 5 can be installed on the ground through the holes opened by the installation ribs 1 .

As shown in Figure 1 and Figure 2, it is characterized in that: the bottom of the base 5 is provided with a moving frame 17, the base 5 is fixedly installed on the moving frame 17 through multiple sets of bolts, and the bottom of the moving frame 17 is provided with four groups of universal wheels. When the prohibition card is moved, the device can be easily moved by installing the prohibition card on the moving frame 17, thereby realizing the purpose of saving manpower and improving work efficiency.

The specific usage mode and function of this embodiment:

Before using the forbidden card, firstly install the base 5. When it is necessary to adjust the working height of the forbidden card and the electric telescopic rod 41, turn the handle 13 to make the sleeve 26 rotate clockwise in the outer cylinder 4, and then make the telescopic The column 25 rises. When the working height needs to be reset, step on the pedal 2 to make the L-shaped slider 21 rise, drive the wedge-shaped block 27 to disengage from the cooperation with the ratchet 16, release the rotation limit of the sleeve 26, and let the telescopic column 25 above the The parts are reset in the vertical direction under the action of their own gravity;

After completing the adjustment of the working height, the hydraulic cylinder 35 is pushed forward to drive the rack frame 34 forward, and then the cradle 39 on the mounting base 3 is rotated clockwise, so that the electric telescopic rod 41 and the top-fixed prohibition card body 15 Lower it to complete the prohibition warning operation. When it is necessary to suspend the prohibition warning operation, make the hydraulic cylinder 35 move back. Similarly, the prohibition card body 15 and the electric telescopic rod 41 can be lifted upward, and the electric telescopic rod 41 can be lifted upward. At the same time, it can be shortened, so that the device can adapt to a narrower working environment;

When multiple roads need to be warned, the motor 10 can be driven to drive the first gear 9 fixed at the end of its output shaft to rotate, so that the mounting base 3 rotates around the axis of the connecting shaft with the telescopic column 25, thereby changing the prohibition sign The orientation of the main body 15 achieves the effect of warning multiple roads.

The basic principles and main features and advantages of the present invention have been shown and described above, and it will be apparent to those skilled in the art that the present invention is not limited to the details of the above-described exemplary embodiments.
