Specific embodiment

The technical solution of the patent is explained in further detail With reference to embodiment：

Embodiment 1

Referring to Fig. 1, a kind of construction lifting device, including braced frame 1, bottom is fixedly installed in braced frame 1 Motor housing 15, motor housing 15 is interior to be equipped with clockwise and anticlockwise motor 18, and level is fixedly installed with level board 12, positive and negative rotation in braced frame 1 The output shaft coaxial surface of motor 18, which is arranged, is fixed with master gear I17, the two sides master gear I17 rotary type set there are two be symmetrical arranged Driven shaft I16 and driven shaft II19, driven shaft I16 and the surface driven shaft II19 are respectively arranged to be fixed with and nibble with master gear I17 Close the pinion I14 and pinion II20 of connection；Starting clockwise and anticlockwise motor 18 can drive master gear I17 to rotate, master gear I17 band The dynamic pinion I14 and pinion II20 for being engaged with connection is rotated.

Driven shaft I16 and driven shaft II19, which is arranged, is fixed with winding wheel 13, when pinion I14 and pinion II20 is rotated When, driven shaft I16 and driven shaft II19 are rotated with it and are rotate in same direction, and then two winding wheels 13 is driven to rotate.

Horizontal in braced frame 1 to be equipped with lifting basket 6, lifting 6 side wall of basket is fixedly installed with extension board 9, the braced frame 1 Lateral wall is equipped with pulley II7 and pulley III11, and 1 inner sidewall of braced frame is equipped with pulley I2, pulley I2, pulley II7 and pulley Wirerope 10 is wound on III11,10 lower end of wirerope is wound around on winding wheel 13, and 10 lower end of wirerope is fixedly installed with link block 5,5 lower end of link block is connected with the lifting rope 25 being fixed on extension board 9.

The rotation of winding wheel 13 carries out winding to wirerope 10, and wirerope 10 pulls lifting rope 25, Jin Ershi by link block 5 Now lifting basket 6 is promoted, and then realizes the elevated height to the construction material placed in lifting basket 6.And control positive and negative rotation Motor 18 inverts, then realizes that winding wheel 13 sets putting for wirerope 10, and then realizes the decline effect of lifting basket 6, passes through control The positive and negative rotation of clockwise and anticlockwise motor 18, which can be realized, carries out lift action to lifting basket 6, simple to operate, using two winding wheels 13 wirerope 10 carry out winding, and the stationarity that lifting basket 6 is gone up and down greatly improves.

Embodiment 2

On the basis of embodiment 1, as shown in Figure 1-3, in addition, 1 inner sidewall level of braced frame is fixedly installed with postive stop baffle 3, it is vertically fixed the guide post 4 through extension board 9 between postive stop baffle 3 and fixed block 28, it is solid that upper end is arranged in guide post 4 It is scheduled on the limit spring 8 of 3 bottom surface of postive stop baffle, further, upper voussoir 23 is vertical corresponding with lower wedge block 21, under upper voussoir 23 Bottom surface is wedge surface, and the upper surface of lower wedge block 21 is wedge surface, several are uniformly fixedly installed on level board 12 and is being located at lifting basket 6 just The buffering elastic spring coil 24 of lower section；When accident, which occurs, for lifting basket 6 drops, the upper voussoir 23 on basket 6 is gone up and down as lifting basket 6 is downward Mobile, upper voussoir 23 impacts lower wedge block 21 vertically, and the wedge surface of upper voussoir 23 and lower wedge block 21 squeezes sliding, such as Fig. 2 institute Show, lower wedge block 21 is slided together with sliding block 22 into sliding cavity 27,26 deformation of reset spring compression；When upper voussoir 23 is moved to hyposphene When 21 lower section of block, buffering elastic spring coil 24 is shortened by the compressional deformation of lifting basket 6, and in the elastic recovery masterpiece of reset spring 26 Under, reset spring 26 pushes sliding block 22 together with lower wedge block 21 to close lifting 6 one Slideslip of basket, as shown in figure 3, hyposphene at this time The one side of the non-wedge surface of block 21 and upper voussoir 23 abuts under the upward elastic force of buffering elastic spring coil 24, realizes the slow of lifting basket 6 Fixed function after punching effectively prevents the rigid shock after lifting basket 6 drops, and substantially increases the lifting lifting transport of basket 6 and builds Build the safety of material.

Embodiment 3

On the basis of embodiment 2, as shown in Figs 1-4, in addition, 1 inner sidewall level of braced frame is fixedly installed with postive stop baffle 3, it is vertically fixed the guide post 4 through extension board 9 between postive stop baffle 3 and fixed block 28, it is solid that upper end is arranged in guide post 4 It is scheduled on the limit spring 8 of 3 bottom surface of postive stop baffle, link block 5 is located at right above extension board 9, and the quantity of lifting rope 25 is two, and is closed It is symmetrical arranged in wirerope 10, the vertical activity of wirerope 10 runs through postive stop baffle 3；In the lifting process of lifting basket 6, extension board 9 slide up and down along guide post 4, play the role of being vertically directed well, avoid lifting basket 6 and lateral offset shaking occurs, Improve stability；The setting of limit spring 8 can play the buffer function to extension board 9, and maloperation is avoided to cause to go up and down 6 mistake of basket Big lifting height is caused to 3 greater impact of postive stop baffle；The symmetrical lifting rope 25 of two be arranged on each extension board 9 to rise The stress for dropping basket 6 is more uniform, further improves the consistent level of lifting process.

In conclusion the braced frame 1, motor housing 15 and clockwise and anticlockwise motor 18 etc. in the present apparatus are prior art means Direct application, and the connection structure of the components such as fixed block 28, upper voussoir 23 and lower wedge block 21 in the technical program and position Relationship is innovative point of the invention, and structure of the invention is ingenious, and design is reasonable, through the vertical corresponding upper voussoir 23 of setting under Voussoir 21 is realized to the buffering fixed function when going up and down basket 6 and surprisingly dropping, and is avoided it from being impacted by increasing, is substantially increased peace Quan Xing；Two 13 pairs of winding wheel of wirerope 10 carries out winding simultaneously, is drawn by 25 pairs of lifting baskets 6 of lifting rope, is effectively mentioned The high smoothness of lifting 6 lifting process of basket, ensure that the steady lifting of construction material.
