Description
Technical field
The utility model relates to a kind of building construction hoist safety and steady device, belongs to building construction hoist safety protection equipment field.
Background technology
At present, the elevator of construction machine in the prior art generally all is equipped with safety gear; These safety gears are wedge formula and the eccentric wheel type clamping mechanisms by the control of traction insurance steel cable, and this mechanism will utilize steel rope twice, and its conservative factor is just smaller; And the traction insurance steel cable need be debugged installation; Its debugging operations is difficulty quite, takes a lot of work, and is time-consuming; Have again this steel rope because of long term exposure outside, very easily corrosion and losing efficacy also has the friction force that tightly relies on track simple in structure that wedge is taken up; Grip track; Have only elevator to tilt this moment and wedge could be effectively when sensitive, and not steady, facts have proved; There is defective in above-mentioned safety gear, poor safety performance.
The utility model content
The utility model is exactly the shortcoming to prior art, designs a kind of sensitivity, failure-free building construction hoist safety and steady device.
A kind of building construction hoist safety and steady device of the utility model, the technical scheme of employing is:
A kind of building construction hoist safety and steady device comprises suspension ring, and suspension ring internal fixation roller and channel-section steel are provided with the skewback that can slide on the channel-section steel, and suspension ring are fixed on the elevator craning cage, it is characterized in that:
At the cage top jacking system is set, jacking system comprises lever, support, pull bar, shadoof and extension spring, and lever is fixed on the cage top through support; The fulcrum place captive joint pull bar of lever, an end of lever connects skewback through shadoof, and the other end is provided with hook; The head of hook is higher than lever, and end is fixed on the reel of cage, and the end of hook also is provided with extension spring; It is terminal that one end of extension spring is fixed in hook, and the other end is fixed in the cage top.
During use, the head of pull bar connects steel rope, and lever head has a down dip under the action of gravity of self and skewback, until skewback in the channel-section steel bottom; Lever tail does not contact in hook, and when safety failures such as disconnected rope took place, like the wire cable rupture of cage, whole cage glided; Reel is under the effect of self gravitation and extension spring, and is descending with respect to cage, makes hook act on lever tail; Steel rope pull-up under the effect of stay cord simultaneously, lever head was forced and lifted this moment, under the effect of shadoof, skewback was lifted; Make it grip track, prevent that cage from continuing drop, held stationary.
The shadoof bottom is provided with retracing spring, and retracing spring is fixed in suspension ring, and during safe condition, shadoof shrinks, and makes skewback in the channel-section steel bottom.
The lever head midway location is provided with spring, and spring one end is fixed in the lever head midway location, and the other end is fixed in the cage top, helps lifting of lever head.
The advantage of a kind of building construction hoist safety and steady device of the utility model is:
Reasonable in design, workable, control is convenient, and safety and steady property is high, the material-saving that saves time, cost is low, high efficiency.
Description of drawings
The structural representation of a kind of building construction hoist safety and steady device of Fig. 1 the utility model;
The structural representation that the storage rope roll of Fig. 2, a kind of building construction hoist safety and steady device of the utility model and cage are fixing;
Fig. 3, a kind of building construction hoist safety and steady device of the utility model, the structural representation of embodiment 2.
The specific embodiment
A kind of building construction hoist safety and steady device of the utility model, the specific embodiment is:
A kind of building construction hoist safety and steady device, suspension ring 1 are fixed on the elevator craning cage 17, and suspension ring 1 internal fixation roller 2 and channel-section steel 5 is provided with the skewback 2 that can slide on the channel-section steel 5.
At cage 17 tops jacking system is set, jacking system comprises lever 8, support 11, pull bar 10, shadoof 7 and extension spring 16, and shadoof 7 bottoms are provided with retracing spring 3; Retracing spring 3 is fixed on the suspension ring 1, and lever 8 is fixed on cage 17 tops through support 11, the fulcrum place captive joint pull bar 10 of lever 8; One end of lever 8 connects skewback 4 through shadoof 7, and the other end is provided with hook 13, and the head of hook 13 is higher than lever 8; End is fixed on the reel 14 of cage 17, and the end of hook 13 also is provided with extension spring 16, and an end of extension spring 16 is fixed in hook 13 ends; The other end is fixed in cage 17 tops; Roll up simple 14 bottoms draw ring 15 is set, the anchor shaft 18 that draw ring 15 set inside can be up and down, anchor shaft 18 connects cage 17 tops.
Under the normal circumstances, anchor shaft 18 is in draw ring 15 bottoms, and during safety misadventures such as the rope that takes place to break, cage 17 descends, and reel 14 makes the hook 13 that is fixed in reel 14 descend along with cage 17 under extension spring 16 effects, links up with 13 and acts on lever 8 afterbodys, held stationary.
