Abstract

The utility model discloses a lifting block of an attached type lifting scaffold. The lifting block comprises an upper lifting block and a lower lifting block which are in mirror symmetry. The upper lifting block is a square frame enclosed by two horizontal square rods and two vertical square rods which are vertically connected end to end. A plurality of forward holes are distributed in the front side of one vertical square rod at equal intervals. A plurality of lateral holes are distributed in the lateral side of the other vertical square rod at equal intervals. The forward holes are vertical to the lateral holes. A pair of lifting lugs distributed at interval is disposed in the middle of one of the horizontal square rods. The lifting block is simple in structure, convenient and practical.

Description

Attachment type raise scaffold lift block

Technical field

The utility model relates to the scaffold of building field, is specifically related to a kind of attachment type raise scaffold lift block.

Background technology

Along with the develop rapidly of Building Trade in China, highrise building and super highrise building are more and more, adhesion type lifting scaffold is as a kind of auxiliary construction equipment of highrise building and super highrise building external wall construction, compared with the scaffold of transmission, obtained technically very large change: 1, needn't translation frame; 2, exempted frequent dismounting operation, because for climbing frame, it is complete that once assembling just can be used construction afterwards always; 3, be not subject to the restriction of depth of building; 4, manpower and material have been saved greatly; 5, safety factor has had improvement; Based on above these advantages, swift and violent development and popularization on current market, are obtained.

But, the main electric block that relies on that climbs of adhesion type lifting scaffold provides power at present, electric block one end need to be fixed on attachment type raise scaffold, the electric block other end is walked around attachment type raise scaffold and is connected with the lifting bearing being contained on exterior wall, conventionally workman chooses electric block by experience fixed point and electric block are wound around route, this is attachment type raise scaffold dismounting inconvenience not only, affect construction speed, also increased in addition the unstability of attachment type raise scaffold.

Utility model content

The defect existing for above-mentioned prior art, the purpose of this utility model is to provide a kind of attachment type raise scaffold lift block that can improve working security.

For achieving the above object, the technical solution of the utility model is: attachment type raise scaffold lift block, comprise that mirror image is to being much of lift block and lower lift block, upper lift block is the quadra that is vertically connected and surrounds with two vertical square bar head and the tail by two horizontal square bars, wherein a positive equal intervals of vertical square bar is furnished with some forwards hole, the vertical square bar of another root side equal intervals is furnished with some side down holes, forward hole is vertical with side down hole, and wherein the middle part of a horizontal square bar is provided with a pair of lifting otic placode spaced apart.

Compared with prior art, the utility model has the advantage of: lift block comprises that mirror image is to being much of lift block and lower lift block, upper lift block is by forward hole, side down hole is connected with attachment type raise scaffold upper bolt, lower lift block is by forward hole, side down hole is connected with attachment type raise scaffold lower bolt, convenient disassembly, and link position all meets construction reference, no longer rely on workman's experience, when use, electric block chain one end connects the lifting otic placode of upper lift block, other end connecting steel wire ropes one end, the wire rope other end is walked around the lifting otic placode of lower lift block, being fixed on building fixed end promotes on bearing, electric block electric machine rotation afterwards, rise by chain-driving attachment type raise scaffold, simple in structure, processing ease, dismounting electric block is convenient, safety and stability.

Further, also comprise two bracing diagonals and two reinforcement straight-bars, described bracing diagonal from described in be provided with the horizontal square bar middle part that promotes otic placode and extend to the horizontal square bar of another root and vertical square bar junction, described reinforcement straight-bar from described in be provided with the horizontal square bar middle part that promotes otic placode and extend perpendicularly to the horizontal square bar of another root middle part, the supporting capacity that improves lift block, makes lift block more stable.

Further, described lifting otic placode thickness is 16mm, and two gaps that promote between otic placodes are 45mm, conveniently between two lifting otic placodes, pulley is installed, laborsaving and reduce friction.

Further, promoting angle between otic placode and horizontal square bar is 145 °.

Brief description of the drawings

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:

Fig. 1 is the upper lift block front view of the utility model attachment type raise scaffold lift block embodiment;

Fig. 2 is the upper lift block left view of the utility model attachment type raise scaffold lift block embodiment;

Fig. 3 is the lower lift block front view of the utility model attachment type raise scaffold lift block embodiment.

Detailed description of the invention

As shown in Figure 1, attachment type raise scaffold lift block, comprise that mirror image is to being much of lift block and lower lift block, the upper lift block upper horizontal square bar 11 of serving as reasons, lower horizontal square bar 12, the quadra that left vertically square bar 21 is vertically connected and surrounds with right vertically square bar 22 head and the tail, a described left side, the right vertically long 650mm of square bar, cross section is the square of 60*60mm, the wherein positive upper forward hole that is furnished with four diameter 18mm with the interval of 200mm of left vertically square bar 21, on right vertically square bar 22 sides, be furnished with the side down hole of four diameter 18mm with the interval of 200mm, forward hole is vertical with side down hole, the middle part of its square bar 11 above the average is provided with left lifting otic placode 31 spaced apart, right lifting otic placode 32, also comprise left bracing diagonal 41, right bracing diagonal 42, left reinforcement straight-bar and right reinforcement straight-bar, left bracing diagonal 41 extends to lower horizontal square bar 12 and left vertically square bar 21 junctions from upper horizontal square bar 11 middle parts, right bracing diagonal 42 extends to lower horizontal square bar 12 and right vertically square bar 21 junctions from upper horizontal square bar 11 middle parts, described reinforcement straight-bar extends perpendicularly to lower horizontal square bar 12 middle parts from upper horizontal square bar 11 middle parts, improve the supporting capacity of lift block, make lift block more stable, left lifting otic placode, right lifting otic placode thickness is 16mm, two gaps that promote between otic placode are 45mm, conveniently between two lifting otic placodes, pulley is installed.

Promoting as shown in Figure 2 angle between otic placode and horizontal square bar is 145 °.

As shown in Figure 3, lower lift block and upper lift block mirror image symmetry, both are in difference, are furnished with the side down hole of four diameter 18mm on left vertically square bar 21 sides of lower lift block with the interval of 200mm, the positive upper forward hole that is furnished with four diameter 18mm with the interval of 200mm of right vertically square bar 22.
