Description
Technical Field
The utility model relates to a portal frame technical field specifically is a folding portal frame.
Background
The portal frame is according to well, daily production needs haulage equipment of little mill (company), warehouse shipment, lift by crane the needs of maintenance heavy equipment and material transportation, the novel small-size jack-up portal frame of developing, to electromechanical device installation, maintenance engineering's portal frame, the portal frame needs often to change different workplaces, and all limited place to some height and width, it just can carry to dismantle repeatedly and install the portal frame, and so comparatively troublesome, and consume time, and the portal frame after the dismantlement needs the supplementary transport of vehicle, so also influence work efficiency, a folding portal frame has been proposed for this, in order to solve the above-mentioned technical problem who proposes.
SUMMERY OF THE UTILITY MODEL
The utility model provides a folding portal frame is in order to solve above-mentioned traditional portal frame of proposing and get into some narrow places and need dismantle the installation repeatedly and just can carry, and also comparatively troublesome problem during the portal frame transport.
The utility model provides a folding portal frame, including landing leg, guide rail, its characterized in that, the first universal wheel of bottom surface fixedly connected with of landing leg, the lateral surface fixedly connected with second universal wheel of landing leg, damping spring has been cup jointed to the bottom of second universal wheel, damping spring is located the inside of landing leg, the guide rail rotates the top of connecting at the landing leg, the guide rail is provided with the rotatory hinge of landing leg with the junction of landing leg, the middle section of guide rail is rotated and is provided with the rotatory hinge of guide rail, the below of the rotatory hinge of guide rail is pegged graft and is had the guide rail bolt, the both ends are all pegged graft and have the landing leg bolt about the guide rail, the other end and the landing leg of landing leg bolt are peg.
Furthermore, the guide rail is divided into two sections, and the two sections of guide rails are rotatably connected through a guide rail rotating hinge.
Furthermore, the guide rail bolts are respectively inserted on the two sections of guide rails.
Furthermore, the number of the second universal wheels is at least three, and the three second universal wheels are distributed in a triangular shape.
A folding portal frame has the following beneficial effects:
through two sections rotatable guide rails and rotatable landing legs, when the portal frame is used, only fixed bolts are required to be detached, then the portal frame can be folded, the trouble of detachment and installation is omitted, the second universal wheels on the side faces of the landing legs can directly push the portal frame away through the second universal wheels after the portal frame is folded, and the trouble of auxiliary carrying of vehicles is omitted.
Drawings
Fig. 1 is a schematic perspective view of the present invention.
Fig. 2 is a schematic front structural view of the present invention.
Fig. 3 is a partially enlarged view of a portion a of fig. 2 according to the present invention.
Fig. 4 is a schematic structural view after the folding of the present invention.
In FIGS. 1-4: the device comprises 1-supporting legs, 2-guide rails, 3-guide rail rotating hinges, 4-guide rail bolts, 5-supporting leg bolts, 6-first universal wheels, 7-second universal wheels, 8-damping springs and 9-supporting leg rotating hinges.
Detailed Description
Please refer to fig. 1 to 4:
the utility model provides a foldable portal frame, which comprises a supporting leg 1 and a guide rail 2, wherein the bottom surface of the supporting leg 1 is fixedly connected with a first universal wheel 6, the outer side surface of the supporting leg 1 is fixedly connected with a second universal wheel 7, the bottom of the second universal wheel 7 is sleeved with a damping spring 8, and the damping spring 8 is positioned inside the supporting leg 1; specifically, the first universal wheel 6 can conveniently move the portal frame when the portal frame works, the second universal wheels 7 distributed in a triangular shape can spread the portal frame after the portal frame is folded, then the portal frame can be directly pushed away through the second universal wheels 7, and the damping springs 8 at the bottoms of the second universal wheels 7 can reduce the impact of the portal frame on the second universal wheels 7 when the portal frame is spread, so that the service life of the second universal wheels 7 is prolonged, as shown in fig. 4;
the guide rail 2 is rotatably connected above the supporting leg 1, a supporting leg rotating hinge 9 is rotatably arranged at the connecting part of the guide rail 2 and the supporting leg 1, a guide rail rotating hinge 3 is rotatably arranged at the middle section of the guide rail 2, a guide rail bolt 4 is inserted below the guide rail rotating hinge 3, supporting leg bolts 5 are inserted at the left end and the right end of the guide rail 2, and the other end of each supporting leg bolt 5 is inserted with the supporting leg 1; specifically, the leg rotating hinge 9 can enable the guide rail 2 and the leg 1 to rotate, the leg bolt 5 can fix the guide rail 2 and the leg 1 to prevent rotation, the guide rail rotating hinge 3 can enable the two sections of guide rails 2 to rotate, and the guide rail bolt 4 can fix the two sections of guide rails 2 to prevent rotation.
To sum up, when the portal frame needs to be folded: guide rail bolt 4, landing leg bolt 5 are taken out from landing leg 1, guide rail 2 respectively earlier, then can rotate each other between guide rail 2, the landing leg 1 to can fold the portal frame, the portal frame after folding can push to the flattening, second universal wheel 7 alright as the removal gyro wheel that supports, as shown in figure 4, only need promote the portal frame and remove alright easily carry the portal frame afterwards.
