The construction elevator balance weight falling protector has simple and reasonable structure, is safe and reliable, solves the hidden trouble that the disadvantage of the balance weight of the prior balance weight elevator brings worry for users for a long time, and guarantees the safe production.
Description
Technical field
The utility model belongs to construction machine, specifically a kind of high-building construction elevator counterweight safety anti-falling device that is used for.
Background technology
Construction elevator has become the important means of building operation vertical transport, plays an important role aspect the safe construction guaranteeing.At present, construction elevator is divided into two kinds of forms in manufacturing and construction use, and a kind of is the band counterweight elevator; Another kind is that non-counterweight elevator, band counterweight elevator are original design, the elevator of long-term use; Non-counterweight elevator is the kind reinstated of new design in recent years, also be because the band counterweight elevator is not in place in the design of counterweight safety system, exist design defect to grow up, both compare, potential safety hazard and accident that the latter has avoided counterweight to overstep the limit and fall, but in actual use, the former mechanical abrasion is little, little power consumption, life-span height, belong to energy-saving equipment, therefore, to its well designed, to transform the counterweight safety system just very necessary, after solving this type of problem, should be to advocate the environment-friendly type equipment that uses.
In actual use, the safety misadventure that counterweight is overstepped the limit, blocks, fallen usually takes place in the band counterweight elevator, major safety risks have been become, there are many band counterweight elevators in my unit, before 2006, phenomenon derailed and that block takes place repeatedly, counterweight is fallen and is taken place thereupon, though owing to do not cause personnel casualty accidents by sheer good luck, every generation direct economic loss once is all very big.For this reason, the root of thoroughly eradicating potential safety hazard is a major issue anxious to be solved.
Summary of the invention
The purpose of this utility model is to have hidden danger for eliminating the above construction elevator counterweight, provides a kind of simple and reasonable, in case the counterweight wire rope breaking.Prevent that counterweight from falling, the construction elevator counterweight safety anti-falling device of safety assurance is provided.
The technical solution of the utility model is: a kind of construction elevator counterweight safety anti-falling device is characterized in that: comprise bolts and nuts, anti-fall hook, the steel rope collar and extension spring that the bolt of the free bearing that is welded on the counterweight, band andgudgeon axle usefulness and nut, connecting panel, short hinge are used; The lower end of described connecting panel is connected with free bearing by the bolt and the nut of band andgudgeon axle usefulness; Be provided with hinge axis hole in the middle of the connecting panel, and be connected with anti-fall hook by short hinge bolt and nut; Have a hole to be used for adorning the steel rope collar at the hook place of anti-fall hook, described steel wire loop ring set is on the pulling steel rope of counterweight; Extension spring is contained on anti-fall hook and the counterweight, and anti-fall hook is pulled to construction elevator support one side all the time; Both sides are welded with two and are used for placing restrictions on anti-fall hook amplitude of fluctuation buting iron on described connecting panel top.In the hook groove of described falling protector hook, also be provided with at least one horizontal iron wire.
A kind of construction elevator counterweight safety anti-falling device that the utility model provides, simple and reasonable, safe and reliable, solve existing counterweight elevator counterweight drawback and caused puzzlement hidden danger to the user for a long time, safety in production is guaranteed.
Description of drawings
Fig. 1 is the scheme drawing on the utility model installation elevator counterweight.
The specific embodiment
Describe the utility model in detail below in conjunction with accompanying drawing.
Shown in Figure 1, the scheme drawing on the utility model installation elevator counterweight.A kind of construction elevator counterweight safety anti-falling device is characterized in that: comprise bolts and nuts 4, anti-fall hook 5, the steel rope collar 6 and extension spring 7 that the bolt of the free bearing 1 that is welded on the counterweight, band andgudgeon axle usefulness and nut 2, connecting panel 3, short hinge are used; The lower end of described connecting panel 3 is connected with free bearing 1 by the bolt and the nut 2 of band andgudgeon axle usefulness; Be provided with hinge axis hole in the middle of the connecting panel, and be connected with anti-fall hook 5 by short hinge bolt and nut 4; Have a hole to be used for adorning the steel rope collar 6 at the hook place of anti-fall hook 5, described steel wire loop ring set is on the pulling steel rope of counterweight; Extension spring 7 is contained on anti-fall hook 5 and the counterweight, and anti-fall hook is pulled to construction elevator support one side all the time; Both sides are welded with two and are used for placing restrictions on anti-fall hook 5 amplitude of fluctuation buting iron on described connecting panel 3 tops.In the hook groove of described falling protector hook, also be provided with the horizontal iron wire 8 in four roads, as the anti-impact force effect.
In case when the utility model was broken and caused that counterweight is fallen at construction elevator counterweight steel rope, hook linked with steel rope, hook saves with elevator standard rapidly under the effect of spring and is affiliated to, and counterweight is affiliated to safely on the construction elevator support.
Because the weight of counterweight is very big, falling protector must play a role in the moment of wire cable rupture, otherwise, just lost function behind the generation acceleration/accel, big too even if play a role to integrally-built destructiveness, therefore, anti-fall hook is adopted the prefastening springing.
Because the web member of elevator standard joint, the right side are directly right tiltedly, direction differs, more complicated, in order to play due effect when hook plays a role, hook must possess the function of the oneself's adjustment that swings, and therefore, the hook body of linking up with is adopted the design of universal-joint.
Because mass when having an effect, has certain impulsive force,, in the hook groove of falling protector hook, the horizontal galvanized wire in 4 roads is set, as the anti-impact force effect in order to reduce owing to the damage of impulsive force to the standard knot web member.
