Detailed Description
Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention. It should be noted that in the description of the present invention, the terms "front", "back", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate directions or positional relationships based on those shown in the drawings, which are merely for convenience of description, but do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. It should also be noted that, unless expressly stated or limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly and include, for example, fixed or removable connections or integral connections; can be mechanically or electrically connected; either directly or indirectly through intervening media, or through both elements. The specific meaning of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
A herringbone ladder capable of lifting goods is formed by hinging a pair of ladder frames 1, and each ladder frame 1 is provided with two upright posts and a plurality of ladder boards 12 positioned between the two upright posts, as shown in figure 1. A rope 13 is connected between the pair of ladder frames 1 in order to form a stable structure of a triangle.
Referring to fig. 1, 2 and 3, the vertical rods at two sides of the ladder rack 1 are groove-shaped vertical rods 11 with outward notches, and a folding goods shelf 2 is arranged on one ladder rack 1. In order to reduce the weight, in the present embodiment, the material of the groove-shaped vertical rod 11 is aluminum alloy.
The folding shelf 2 comprises a pallet 21, a stay 24 and a pair of slide bars 22, wherein the pair of slide bars 22 are respectively hinged on both sides of the pallet 21. One end of the stay bar 24 is hinged with the slide bar 22 and the other end is detachably connected with the pallet 21. Specifically, in the present embodiment, a pin is provided on a side surface of the pallet 21, a fork structure is provided on the other end of the stay 24, and the stay 24 and the pallet 21 are detachably connected by the fork structure and the pin. When the goods 4 need to be lifted, the fork-shaped structure of the support rods 24 is abutted against the pin shafts, so that the goods plate 21, the support rods 24 and the slide rods 22 form a stable triangular support structure which can enable the goods plate 21 to keep a horizontal support state. As shown in fig. 4, when the goods 4 do not need to be lifted, the fork-shaped structure is separated from the pin shaft, so that the goods plate 21 and the support rods 24 can be folded, and the use space of the herringbone ladder is not occupied.
The sliding rod 22 is positioned in a notch of the groove-shaped upright 11 and can move up and down along the groove-shaped upright 11. In order to reduce the frictional resistance, the slide bar 22 is provided at both ends with rollers 23, which rollers 23 can roll in the notches of the channel uprights 11. A chain block 3 is arranged at the hinged position of the pair of ladder frames 1, the chain block 3 is provided with a fixing hole, and the fixing hole is coaxially connected with the hinged shaft of the pair of ladder frames 1. The chain block 3 has a zipper 31 and a drag chain 32, wherein the drag chain 32 is connected to the folding pallet 2.
The chain block 3 is also called a chain block, and the chain block 3 is a manual hoisting cargo which is simple to use and convenient to carry. The chain block 3 uses the principle of wheel shafts, thereby playing a role of saving labor. The chain block 3 is internally provided with a ratchet mechanism which can realize self-locking. The zipper 31 is positively pulled to lift the goods 4 by the drag chain 32, and is reversely pulled to lower the goods 4 by the drag chain 32.
In operation, the pallet 21 is first supported by the support rods 24 to form a pallet, and the goods 4 are then placed on the pallet 21. Finally, the zipper 31 is pulled to pull the goods shelf to rise along the groove-shaped upright rod 11, so that the goods 4 are lifted. When unloading, the slide fastener 31 is pulled in the reverse direction to lower the load 4. Because chain block 3 has the effect of provincial power, constructor can accomplish the lift of goods 4 on ground. Like this, constructor need not carry 4 ladders of goods, has not only alleviateed constructor's burden, has still avoided the potential safety hazard.
The details of which are not described in the prior art. Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
