Abstract

The utility model relates to a multi-stage elevating platform, which is provided with a bottom fixing frame, a middle multi-stage elevating frame and a top elevating frame. The utility model is characterized in that eight pulley wheels are respectively arranged on an every stage elevating frame of the middle multi-stage elevating frame; pulley wheels are also arranged on the lower end of the top elevating frame; the pulley wheels are divided into four groups according to an upper corresponding position and a lower corresponding position; a pulley groove of each group of the pulley wheels is past through by a wire rope; the upper end head of each of the wire ropes is past through a guide wheel and is wound on a winding mechanism of the top elevating frame; the lower end head of each of the wire ropes is connected with the bottom fixing frame. The utility model is widely used in loading and unloading of goods in various fields, and has the advantages of simple structure and low cost.

Description

The multistage lifting platform

The utility model relates to a kind of bay-lift of handling goods.

At present the bay-lift (machine) that cargo handing is used in the storehouse mostly is hydraulic hoist greatly, its complex structure, and the cost height repairs very complicatedly, and very heavy, more is not suitable for the use of transporting and raise of decorative craft of building goods.

The purpose of this utility model is to overcome the deficiency of above-mentioned prior art, and multistage lifting platform a kind of simple in structure, with low cost, applied widely is provided.

The purpose of this utility model realizes by following technical proposals:

The multistage lifting platform has the bottom fixed mount, the top crane of band tip platform, be located at the middle multi-stage crane between bottom fixed mount and the top crane, its technical scheme is that each grade crane in the middle multi-stage crane all is separately installed with eight pulleys, these eight pulleys be located at respectively described each grade crane inboard on, down, a left side, right, before, eight ends position, angle, back, the left side of inboard, crane lower end, top, right, before, four ends angle, back respectively is equipped with a pulley, crane upper end, top has track adjusting wheel, described each a grade crane and a crane left side, top, right, before, the pulley of back position is by last, following opposite position is divided into four groups, the race of every group of pulley passes a steel rope, the upper end of every steel rope passes on the hoisting mechanism on the tip platform that track adjusting wheel is wound in the top crane, and the lower end of every steel rope is connected with the bottom fixed mount respectively.

The utility model is because each grade crane in the middle multi-stage crane all is separately installed with eight pulleys, these eight pulleys be located at respectively described each grade crane inboard on, down, a left side, right, before, eight ends position, angle, back, the left side of inboard, crane lower end, top, right, before, four ends angle, back respectively is equipped with a pulley, crane upper end, top has track adjusting wheel, described each a grade crane and a crane left side, top, right, before, the pulley of back position is by last, following opposite position is divided into four groups, the race of every group of pulley passes a steel rope, the upper end of every steel rope passes on the hoisting mechanism on the tip platform that track adjusting wheel is wound in the top crane, and the lower end of every steel rope is connected with the bottom fixed mount respectively.Like this, it is simple in structure, has saved material, and is with low cost; It is stressed evenly simultaneously, steadily of centre of gravity, though weight is little, load-carrying capacity is strong, can be widely used in the cargo handing of various industries, for example the cargo handing in industry such as decorative craft of building, low layer elevator and warehouse.

The utility model is described in further detail below in conjunction with embodiment:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 be among Fig. 1 the middle multi-stage crane wherein the A of one-level crane to view.

Fig. 3 is along the part sectional view of B-B line among Fig. 2.

As Fig. 1, Fig. 2, shown in Figure 3, the utlity model has bottom fixed mount 8, band tip platform 2 top crane 5, be located at the individual pulley of middle multi-stage crane 1, winch 3,8n (n is the progression of middle multi-stage crane) between bottom fixed mount 8 and the top crane 57, four pulleys 7 ', track adjusting wheel 4, four steel ropes 6.The chassis 9 of bottom fixed mount 8 below it is affixed, and winch 3 is located on the platform 2 of top crane.Each grade crane 1a in bottom fixed mount 8, top crane 5 and the middle multi-stage crane 1 is the cuboid framework, and each framework is by four

Shape steel plate (or steel tubes) is column 1aa, and angle steel 1ab and this column 1aa welding are formed framework.Top crane 5 and each grade crane are to do to slide up and down in the next stage framework, and its sliding rail is 90 ° of end angles of four columns of next stage.Each grade crane 1a in the middle multi-stage crane is separately installed with eight pulleys 7, these eight pulleys 7 are located at eight ends of up, down, left, right, before and after position, angle of described each grade crane 1a inboard respectively, end angle, four of the left, right, front and rear of inboard, top crane 5 lower end respectively be equipped with a pulley 7 ', crane 5 upper ends in top have track adjusting wheel 4, and track adjusting wheel can be can be around the beaming roller of top crane rotation.Each pulley 7 (or pulley 7 ') be installed on the sheave shaft 10, being provided with antifriction-bearing box 12 between sheave shaft 10 and the pulley 7, sheave shaft 10 is by the column 1aa and the adapter plate 11 spacing supports of said frame, and adapter plate 11 is welded on the angle steel 1ab that forms said frame.The pulley of described each grade crane 1a and position, top crane 5 left, right, front and rear is divided into four groups by upper and lower opposite position, the race of every group of pulley passes a steel rope 6, the upper end of every steel rope 6 passes on the hoisting mechanism 3 on the tip platform that track adjusting wheel 4 is wound in the top crane, and the lower end of every steel rope 6 is connected with bottom fixed mount 8 respectively.
