Description
Technical Field
The utility model relates to a double ladder field, concretely relates to double ladder by oneself.
Background
In indoor engineering construction such as power wiring installation, a herringbone ladder is one of common tools. The existing herringbone ladder comprises a fixed type herringbone ladder and a foldable herringbone ladder. However, when the existing various herringbone ladders need to be moved again in the actual use process, the herringbone ladders can only be taken down from the ladder and then are taken up to the next position to continue the operation. Therefore, the reciprocating movement wastes time and labor, and the working efficiency is seriously reduced. The existing movable herringbone ladder has the problems of complex structure, high manufacturing cost, inconvenient use and the like, and is not widely used.
Disclosure of Invention
The utility model discloses the technical problem that will solve is: provides a self-propelled herringbone ladder with simple structure, low cost and convenient use.
The technical solution of the utility model is that: the self-propelled double ladder comprises a left ladder frame and a right ladder frame, wherein walking wheels are arranged on two sides of the bottom of the left ladder frame and the bottom of the right ladder frame, a connecting rod is hinged to a position, close to the top, of each side frame of one ladder frame, the free end of each connecting rod is hinged to a support rod device, each support rod device comprises a hand-held rod, a connecting rod and two support rods, the two support rods are arranged on two sides of the double ladder respectively and are hinged to the corresponding connecting rod respectively, the top ends of the support rods are higher than the top of the double ladder, the bottom ends of the support rods are in contact with the ground, the hand-held rods are connected between the top ends of the two support rods, and the connecting rods are connected between the bottom ends of the.
The technical effects of the utility model are that: it has simple structure, low cost and convenient to use's advantage, when using the ladder, can stand alone on the ladder and need not just go up the process that the walking wheel was accomplished to the cooperation of vaulting pole and removed the ladder with earth.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
As shown in figure 1, the self-propelled herringbone ladder comprises a left ladder frame 1 and a right ladder frame 2, wherein the left ladder frame 1 and the right ladder frame 2 are connected at the top through hinges, the left ladder frame 1 and the right ladder frame 2 can be folded and can be locked in an opening state through a locking device after being opened, it is characterized in that the two sides of the bottom of the left ladder frame 1 and the right ladder frame 2 are both provided with walking wheels 3, one ladder frame is respectively hinged with a connecting rod 5 at the position of the two side frames 4 near the top, the free end of the connecting rod 5 is hinged with a support rod device, this vaulting pole device includes hand-held rod 6, connecting rod 7 and two vaulting poles 8, and two vaulting poles 8 set up respectively in the both sides of double ladder and articulated with a connecting rod 5 respectively, and the top of vaulting pole 8 exceeds the top of double ladder, and the bottom and the ground contact of vaulting pole 8, hand-held rod 6 are connected between the top of two vaulting poles 8, and connecting rod 7 is connected between the bottom of two vaulting poles 8.
The bottom end of the stay bar 8 is sleeved with a rubber sleeve 9. The rubber sleeve 9 can increase the friction force with the ground.
When the herringbone ladder is in an open state, a person can operate the strut device by standing on the ladder, and the herringbone ladder can be supported on the ground by the strut device through swinging to move back and forth.
Claims (2)
