Description

Technical Field

[0002] Firefighting pipes are pipe systems specially used to transport firefighting water or other fire extinguishing agents. They provide the water source required for firefighting when a fire occurs, ensuring the normal operation of firefighting facilities. Temporary firefighting pipes are pipe systems temporarily set up to meet firefighting needs in specific situations. They are usually used at construction sites. During the installation of temporary firefighting pipes, installers need to carry the firefighting pipes through a scissor-type lift to the corresponding position of the pipe support and then push the pipes into the pipe support. Manual operation is slow, especially for heavy or large pipes. It often takes a long time to transport and install them, affecting the overall construction progress. There are certain safety hazards when manually pushing the pipes.

[0045] Working principle: First, control the conveyor vehicle 1 to move to the corresponding position, and then the operator enters the working platform 3. After controlling the scissor lift platform 2 to drive the operator to rise to the corresponding position for installing the fire-fighting pipe, control the crane body 4 to drive the lifting frame 5 to descend to the ground, and then place the temporary fire-fighting pipe to be installed on the position corresponding to the friction conveyor roller 606 in the lifting frame 5. After the pipe is placed, control the No. 1 electric cylinder 617 to start. The driving end of the No. 1 electric cylinder 617 drives the sliding protrusions 602 at both ends to move under the guidance of the guide frame 601 through the connecting plate 616, as shown in FIG. Figure 4As shown, the sliding protrusion 602 pushes the lifting protrusion 603 to rise under the guidance of the guide frame 601. The lifting protrusion 603 drives the fixed frame 604 and the friction conveying roller 606 to rise synchronously, and at the same time drives the flip rod 607 to flip around the rotation connection with the limit block 609, so that the No. 1 ball 618 fits the outer wall of the fire protection pipe. At this time, the friction conveying roller 606 cooperates with the two No. 1 balls 618 to clamp the outer wall of the fire protection pipe. When the flip rod 607 flips, the No. 1 return spring 611 is stretched. Figure 7 As shown, the connecting plate 616 drives the lifting plate 701 to descend under the guidance of the guide rail 712 through the connecting rod 713 during the movement, and the lifting plate 701 drives the corresponding No. 1 limit frame 703 and No. 2 limit frame 704 to rotate in the opposite direction on the guide wheel 710 and the arc groove 711 on the guide bracket 702 through four driving rods 709. Under the action of the No. 2 return spring 708, the plug 705 and the fixing block 706, the No. 2 ball 707 is always in contact with the outer wall of the fire pipe. The fire pipe is limited by the rotation of the No. 1 limit frame 703 and the No. 2 limit frame 704, and then the crane body 4 is controlled to drive the lifting frame 5 and the fire pipe to rise to the position corresponding to the pipe bracket. The operator adjusts the pipe conveying direction according to the installation direction of the fire pipe, as shown in FIG. Fig.10 As shown, the No. 2 electric cylinder 809 is controlled. The No. 2 electric cylinder 809 drives the friction transmission frame 806 to slide on the rotating shaft 802 through the lifting rod 807, and is tightly fitted with the conical friction blocks 805 corresponding to the No. 1 bevel gear 803 and the No. 2 bevel gear 804, respectively. When the friction transmission frame 806 is tightly fitted with the conical friction blocks 805 corresponding to the No. 1 bevel gear 803, the No. 3 bevel gear 811 rotates clockwise through the No. 1 bevel gear 803 to drive the rotating shaft 802 to rotate clockwise, as shown in FIG. Figure 5 As shown, the rotating shaft 802 rotates clockwise through the first bevel gear 614 and the second bevel gear 615 to drive the transmission shaft 612 to rotate clockwise, and the right transmission shaft 612 drives the right transmission shaft 612 to rotate synchronously clockwise through the synchronous wheel transmission group. The two transmission shafts 612 respectively drive the corresponding rotating shafts 605 to rotate synchronously clockwise through the synchronous wheel transmission group. When the rotating shaft 605 rotates, the friction conveying roller 606 is driven to rotate synchronously. When the friction conveying roller 606 rotates clockwise, the fire-fighting pipeline is transported to the right. When the friction transmission frame 806 is tightly fitted with the corresponding conical friction block 805 on the No. 2 bevel gear 804, the No. 3 bevel gear 811 rotates clockwise through the No. 2 bevel gear 804 to drive the rotating shaft 802 to rotate counterclockwise, and according to the same steps as above, the friction conveying roller 606 is driven to rotate counterclockwise. At this time, the fire-fighting pipe is transported to the left. After the conveying direction is adjusted, the driving end of the control motor 812 drives the driving shaft 810 to rotate clockwise. After the fire-fighting pipe enters the corresponding pipe bracket, it is adjusted and installed by the operator.

Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
