The column that described lifting table comprises rectangular flat and is connected with described rectangular flat both sides, this column is provided with steel rope set collar.
Described safety protection mechanism comprises upper and lower two fixed pulleys and steel rope, and described steel rope is fixed on described steel rope set collar.
Contribution of the present utility model is, it efficiently solves existing scissor-type lifting platform platform, less stable, and the problem such as cargo capacity is little, and solved common cargo lift and be subject to the problem that affects of object size and weight restriction, there is following beneficial effect:
The utility model adopts the hydraulic elevating platform assembly of framed structure; not only convenient and swift finishing the work; be not subject to the restriction of the factors such as space; greatly increase work efficiency; be applicable to very much the vertical carrying of large scale object and special object; and there is load limitation device and infrared ray safety protection structure, and can guarantee goods and the people safety at working process, very practical.
[accompanying drawing explanation]
Fig. 1 is front schematic view of the present utility model.
Fig. 2 is the A portion enlarged diagram of Fig. 1.
[specific embodiment]
As shown in Figure 1, the utility model elevating platform assembly comprises framed structure, lifting table, steel rope 3, hydraulic gear 5, electric control system 6 and safety protection mechanism.Framed structure comprises left side column 11 and two, right side column 12, in left side column 11 and two column 12 upper ends, be provided with crossbeam 13, left side column 11, two, right side column 12 and crossbeam 13 are welded as a whole, and left side column 11, two, right side column 12 and crossbeam 13 are selected metal channel-section steel or I-beam section material.Column 11 tops, left side are provided with fixed pulley 41, and its underpart is provided with 42, two right side column 12 tops of fixed pulley and is respectively equipped with two fixed pulleys 44,45.
As shown in Figure 1, lifting table is as the carrier of goods, it comprises rectangular flat 22 and two of left and right column 21, two columns in rectangular flat 22 and left and right 21 are conventional metallic material, these two columns 21 and rectangular flat 22 both sides weld togethers, be provided with two reinforced ribs in column 21 both sides, and this reinforced rib upper end is welded on column 21 tops, reinforced rib lower end and rectangular flat 22 weld, and reinforced rib further plays the effect of reinforcing this lifting table.On column 21, be provided with steel rope set collar 211.Hydraulic gear 5 is known hydraulic gear, on the operating mechanism top of hydraulic gear 5, is provided with fixed pulley 43, and the fixed pulley 43 in the Hydraulic Cylinder operating mechanism of hydraulic gear 5 inside does straight line up-and-down movement.Electric control system 6 is known electric cabinet, controls lifting table rising, declines and stops etc.
As shown in Figure 1, article two, steel rope 3 lower ends are fixed on the left side of right side column 12 bottoms adjacent with left side column 11, this connecting portion is also provided with load limitation device 8, when load excessive, load limitation device 8 sends signal to electric control system 6, electric control system 6 sends danger signal, makes device out of service.Article two, a steel rope in steel rope 3 is walked around fixed pulley 43, fixed pulley 42, fixed pulley 41, fixed pulley 44 and is fixedly connected with the bottom of the left side column 21 in lifting table, and another steel rope is walked around fixed pulley 43, fixed pulley 42, fixed pulley 41, fixed pulley 44 and fixed pulley 45 and is fixedly connected with the bottom of the right side column 21 in lifting table.
