the drive division includes drive gear 4, rack 5 and bottom plate 6, drive gear 4 fixed connection is in center pin 14, center pin 14 rotate connect in ladder frame 1, the tip fixed connection of center pin 14 is in rocking handle 7, the lower extreme fixed connection of rack 5 in the upper surface of bottom plate 6, the lower surface of bottom plate 6 rotates respectively to be connected in a plurality of gyro wheels 15, bottom plate 6 sliding connection in spout 3, drive gear 4 mesh in rack 5 for drive bottom plate 6 for ladder frame 1 reciprocates.
The working process of the insulating step ladder for the power distribution room comprises the following steps:
when an operator needs to move the ladder frame 1, one hand holds the ladder frame 1, the other hand holds the rocking handle 7 and rocks the rocking handle 7 to drive the central shaft 14 and the driving gear 4 to rotate in the forward direction, so that the rack 5 is driven to move downwards relative to the ladder frame 1, and the bottom plate 6 is driven to slide downwards relative to the chute 3, so that the rollers 15 move to the position below the chute 3. The operator keeps the relative position of the rocking handle 7 and the ladder 1 unchanged, i.e. the relative position of the plurality of rollers 15 and the ladder 1 unchanged, so that the rollers 15 are always located below the runners 8, and then pushes the ladder 1 forward to the desired position. When the ladder frame 1 is moved to a desired position, the operator releases the rocking handle 7, the ladder frame 1, the driving gear 4 and the central shaft 14 slide down under the action of their own gravity, and at the same time, the plurality of rollers 15 return to the inside of the chute 3 again, and at the same time, because the rack 5 and the driving gear 4 are engaged with each other, the driving gear 4 and the central shaft 14 rotate in the opposite direction for the operator to rock the rocking handle 7 next time.
In the technical scheme of the utility model, when the ladder frame 1 moves to the required position, the plurality of rollers 15 are positioned in the sliding groove 3, the lower end surface of the sliding groove 3 is stably attached to the ground, and the stability of the whole ladder frame 1 is ensured when an operator stands on the pedal 2; meanwhile, when people need to move the ladder frame 1, the rocking handle 7 is shaken to enable the ladder frame 1 to rise relative to the ground by the height distance of the roller 15, and the ladder frame 1 can be moved by rolling the roller 15.
Specifically, the ladder frame 1 is fixedly provided with a reinforcing bar rod 16 for reinforcing the overall mechanical strength of the ladder frame 1.
As shown in fig. 1 and 2, in a specific embodiment, the driving portion further includes a slide rail 8, the slide rail 8 is fixedly mounted on the ladder rack 1, and the rack 5 is slidably connected to the slide rail 8.
In the above embodiment, specifically, the chute 3 extends in the vertical direction, and only through the sliding connection relationship between the bottom plate 6 and the chute 3, the rack 5 is constrained to slide in the vertical direction, that is, the rack 5 is prevented from deflecting in the horizontal direction; in the present embodiment, the slide rail 8 extends in the vertical direction, and the rack 5 is disposed between the slide rail 8 and the driving gear 4, so as to further avoid the rack 5 from deviating in the horizontal direction, and ensure the stable meshing relationship between the rack 5 and the driving gear 4.
As shown in fig. 1 and 2, in a specific embodiment, the ladder frame 1 is provided with a through hole 9, one end of the rocking handle 7 away from the central shaft 14 is connected to a tube 10, a limiting rod 11 is embedded in the tube 10, and the limiting rod 11 is inserted into the through hole 9 and is used for limiting the rotation of the driving gear 4, so that the rollers 15 are stabilized below the chute 3.
In this embodiment, it is concrete, when the operator needs to promote ladder frame 1 to required position, the operator rocks rocking handle 7, when a plurality of gyro wheels 15 relative movement to spout 3 below, bottom plate 6 is still in spout 3 time, body 10 corresponds to through-hole 9, at this moment peg graft gag lever post 11 in through-hole 9, rocking handle 7 just can not rotate, thereby drive gear 4 just can not rotate, thereby rack 5 just can not reciprocate, thereby a plurality of gyro wheels 15 just are restricted in spout 3 below, the operator is at the in-process that removes ladder frame 1, just need not hold rocking handle 7, so more make things convenient for the operator to remove ladder frame 1.
In the specific embodiment, the pedal further comprises a plurality of anti-slip pads, and each anti-slip pad is attached to the upper surface of one of the pedals 2.
In the embodiment, the non-slip mat is made of rubber, and on one hand, the rubber has insulating property; on the other hand, the surface of the rubber non-slip mat is easy to be processed into an uneven surface so as to increase the friction force when an operator steps on the mat.
In a specific embodiment, the ladder frame 1 is made of unsaturated polyester resin.
In the present embodiment, the ladder frame 1 is made of unsaturated polyester resin, so that the ladder frame 1 is light in weight and high in mechanical strength, and an operator can easily move the ladder frame 1. The central shaft 14 is made of stainless steel, and a bearing is arranged at the rotating connection position of the ladder frame 1 and the central shaft 14, so that the rotating stability of the central shaft 14 is ensured.
In the embodiment shown in fig. 2, the upper end of the rack 5 is fixedly connected to a stopper 12 for preventing the bottom plate 6 from being separated from the chute 3.
In this embodiment, specifically, when the driving gear 4 drives the rack 5 to move downward for a certain distance, the roller 15 moves to the lower side of the chute 3, and meanwhile, the stopper 12 abuts against the upper end of the slide rail 8, so as to prevent the rack 5 from continuing to move downward and prevent the bottom plate 6 from separating from the chute 3, thereby ensuring that the horizontal positions of the roller 15 and the ladder frame 1 are kept unchanged.
In a specific embodiment, the plurality of pedals 2 comprise a first pedal 2, a second pedal 2 and a third pedal 2, and the first pedal 2, the second pedal 2 and the third pedal 2 are sequentially spaced by 40 cm.
In the present embodiment, the vertical distance between adjacent steps 2 is kept at 40cm, matching the step height of a typical operator, and facilitating the ascending work of the operator.
In the embodiment shown in fig. 1, the ladder 1 is fixedly attached at its sides to handles 13.
In this embodiment, specifically, the operator can pull the ladder rack 1 forward by holding the handle 13.
The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
