Abstract
The utility model provides a scaffold fall protector disposed on a scaffold wall-attached device. The fall protector is composed of matching stair rods between a cam mechanism and a body guide of a scaffold body. The cam mechanism comprises a cam and a torsion spring. The stair rods are in rack structure. The cam is disposed at the end of a wall-attached support of the wall-attached device and is in contact fit with the stair rods. One end of the torsion spring is connected with the cam, and the other end of the torsion spring is connected with the wall-attached support. The scaffold fall protector has the advantages that the fall protector in the cam mechanism structure is simple in structure and low in production cost; operating stability of a scaffold is guaranteed; When a scaffold body falls, the eccentric cam is locked between the stair rods by the scaffold body increasing in speed; and accordingly, fall-protecting stop of the scaffold body is achieved and construction safety of the scaffold body is ensured.
Description
Technical field
The utility model belongs to the scaffold field, especially relates to a kind of anti-drop device of scaffold.
Background technology
In the construction of highrise building outrigger, commonly used to climbing type scaffold (abbreviation climbing frame).Because climbing frame is applied to highrise building, so that its practicality and safety just seem is particularly important, present climbing frame wire rope in the process that promotes can accident come off, and has great potential safety hazard, threatens construction worker's life security.
Summary of the invention
Problem to be solved in the utility model provides a kind of scaffold anti-drop device.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of scaffold anti-drop device, described anti-drop device are to be cooperated with terraced bar between the scaffold support body guide rail by cam mechanism to form.
Described cam mechanism is arranged on the scaffold wall-attaching equipment, is made up of cam and torsion spring, and described cam is arranged on the attached wall bearing end of described wall-attaching equipment, and described torsion spring one end is connected with described cam and the other end is connected with described attached wall bearing.
Described terraced bar is rack structure.
Described cam cooperatively interacts with described terraced bar and contacts.By the torsion spring fixed angle cam that sets, when cam rocks because contacting with terraced bar, under the effect of torsion spring, reset, and the damping that utilizes torsion spring to reset, cam can freely reset between terraced bar when reaching operate as normal, when meeting accident because of terraced bar by speed greater than the cam reset speed, cause the cam card to be parked between the terraced bar, reach anti-fall stop effect.
Further, described cam is disc cam.
Further, described cam is the swing type eccentric cam.
Further, 90 ° of angles of described torsion spring two ends one-tenth.
Advantage and the good effect that the utlity model has are: owing to adopt technique scheme, anti-drop device adopts cam mechanism simple in structure, and cost of manufacture is cheap; Guaranteed the stability of scaffold work, when support body fell, eccentric cam increased by card by support body speed and is parked between the terraced bar, realized that support body is anti-fall only to stop, and had guaranteed the support body construction safety.

The specific embodiment
The utility model is a kind of anti-drop device of scaffold.Scaffold as shown in Figure 1 and Figure 2 is welded to form by web member (cross bar 9 and brace 5) by guide rail 6 and vertical rod 10; described guide rail 6 is connected and fixed by steady pin with wall-attaching equipment; anti-drop device is arranged on the described wall-attaching equipment 11, and described anti-drop device and anti-dumping guiding device form safety system.Scaffold is divided into joint 1, standard knot 1, standard knot 23 and saves 4 down, and the described 4 bottoms welding of joint down is as the double flute steel on chassis.As shown in Figure 3, Figure 4, anti-drop device adopts the swing type eccentric cam, and cam is provided with torsion spring mechanism.
Scaffold main frame of the present utility model adopts the integral type design, and main frame is welded to form by web member by support body guide rail and outer support body vertical rod.Guide rail adopts two 6.3# channel-section steels, and not only having ensured the main frame bulk strength but also can be the support body lifting provides track.As shown in Figure 2, being provided with the D30 round steel every 150mm between the guide rail makes anti-fall terraced bar 8 and shores a little, can guarantee that support body is anti-fall only stops distance control in 80mm, on guide rail, be provided with simultaneously the pinned hole 7 of D32mm every 450mm, D31 steady pin by modifier treatment can be connected and fixed support body and wall-attaching equipment, guarantee effectively being passed in the building structure of support body load, it is fixing safe and reliable to guarantee that support body adheres to.Joint bottom welding 10# double flute steel transmits deadweight and the working load of whole frame body as the chassis of main frame under the main frame.The suspension hook junction plate adopts " worker " font steel plate to fasten the double flute steel of bottom, bears power whole on the chassis, has guaranteed the stability of support body rigidity, intensity and lifting.
As Fig. 5, shown in Figure 6, YK-1 type anti-drop device is by being set directly at safe anti-drop device on the wall-attaching equipment.All dispose an anti-drop device on each wall-attaching equipment, anti-drop device adopts the swing type eccentric cam, by and the support body guide rail between anti-fall terraced bar contact activation anti-drop device, cam is arranged on the attached wall bearing end of described wall-attaching equipment, and contacts with described terraced bar.Described torsion spring one end is connected with described cam and the other end is connected with described attached wall bearing 12, realizes the swing of cam by the reciprocal damped motion of torsion spring.
The course of work of the present utility model: under the nominal situation, the reset response of torsion spring can freely swing eccentric cam between the Track ladder bar; When support body fell, because support body speed increases, eccentric cam can't reset and is parked between the anti-fall terraced bar by card, thereby realizing that support body is anti-fall only stops, and guarantees the support body construction safety.
More than an embodiment of the present utility model is had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the present utility model.
