Description
Technical field
The utility model belongs to the construction equipment field, relates to a kind ofly making the lifting that stage rope suspension centre easy on and off moves or the movable suspension centre clamp of suspension hanging scaffold.
Background technology
In towering structure (like chimney) construction; The normal bench board that uses a kind of with the suspension of chain block cooperation steel rope; Be commonly called as " hanging scaffold "; Its work characteristics is that the vertical shifting scope is big and move frequently, and it is time-consuming all to require great effort when moving suspension centre whenever, meets also to cause falling or collapsing of hanging scaffold accidentally easily.In chimney turns over mold technique construction, winding tower is arranged in the chimney, steel rope still can depend on winding tower and progressively up or down get point of suspension and move; And when adopting the technology construction of climbing form, no winding tower in the chimney, steel rope do not have and depend on; Needing bench board or framing member with the chimney top is suspension centre; Then the total body overhang of stage rope is long, need take a lift when hanging scaffold will go up and down whenever to go up to the chimney top to go to move its suspension centre, if because of extraordinary circumstances; Then can only walk cat ladder when elevator can't be gone up to the chimney top, this obviously is not satisfy working security and convenience requirement.
Summary of the invention
It is a kind of flexible that the purpose of the utility model is to provide, and can freely adjust height, ability fast lifting hanging scaffold, and guarantee the solid and reliable lifting of suspension centre or the movable suspension centre clamp of suspension hanging scaffold.
Technical scheme below its technical matters that solves the utility model adopts:
Promote or hang the movable suspension centre clamp of hanging scaffold, it is characterized in that: include housing, housing is divided into upper shell and lower house; Clamping between the two has clamp, and described clamp is divided into two groups and is provided with up and down, above one group include clamp left wing and right pellet; Below one group comprise left pellet and clamp right flank, wherein, clamp left wing is shaped as rectangle; Its right hand edge is the tooth bar of arc, and the right of clamp left wing is equipped with right pellet, and the left hand edge of right pellet is a linear gear rack; Described left pellet is welded on the lower house, and its right hand edge is a linear gear rack, and the right of left pellet is provided with the clamp right flank, and the clamp right flank also is a rectangle, and its left hand edge is an arc-shaped rack; The slit of the confession steel wire penetrating that is on the same straight line is left in the described centre of two groups of clamps up and down; Described clamp left wing and clamp right flank tail end are equipped with locking rope; Locking rope is connected with suspension hook; The tail end of clamp left wing and clamp right flank also is equipped with the rope that gets loose, and the rope that gets loose can drive clamp left wing when promoting and the clamp right flank is rotated.
In such scheme, described surface of shell shape is the identical Pear-Shaped of size up and down, and both through bolted connection together.
In such scheme, described clamp left wing and right pellet pass through bolted connection on upper shell.
In such scheme, described clamp right flank is passed through bolted connection on lower house.
The principle of the utility model device is: adopt clamp structure that this device is fixed on the steel rope; When the rope that gets loose was promoted, clamp left wing clockwise rotated, and the clamp right flank rotates counterclockwise; Make the slit between clamp left wing and right pellet, clamp right flank and the left pellet increase; The friction force of clamp and steel rope reduces, and this device can carry out the position adjustment up and down along steel rope, guarantees the alerting ability of suspension centre height and position.
When the rope that gets loose was not promoted, clamp left wing and clamp right flank can not be rotated in the opposite direction, rely on the weight of hoist ceiling crane self, with steel rope and clamp locking, the purpose that reaches the safety suspension or promote.
The main beneficial effect of the utility model is:
1, individual small and exquisite, safe in utilization, light.
2, can relaxedly and rapidly unclamp, can rely on hanging scaffold deadweight auto lock.
3, improve the suspension centre moving velocity, reduced artificial labour intensity.
4, to adopt common sheet material be main material to device of the present invention, has light, economic, practical characteristics, is easy to promote.
