Abstract
The utility model provides a hydraulic drop-proofing system for climbing formwork composed of two mechanical instantaneous action drop-proofing devices which can be operated along the guide rail and guarantee that the system does not fall down. The hydraulic drop-proofing system for climbing formwork comprises two drop-proofing devices and a hydraulic jack. Two drop-proofing devices are held with one upwards and one downwards and are adhered to the guide rail and are fixedly connected by the hydraulic jack. The guide rail is provided with a guide rail bayonet at regular distance. The drop-proofing device comprises a casing a wedge and an elastic device which are arranged in the casing. The wedge is rotatably connected with the casing by the wedge pin shaft. The elastic device is elastically against the lower part of the wedge. The drop-proofing system is safe and has simple structure and can provide dual safe protection.
Description
Technical field
The utility model is the security system that is applied in the hydraulic climbing formwork system of the realm of building construction, especially a kind of mechanical braking formula security system that can play the fall arrest effect.
Background technology
In building trade, safety device is a kind of commonly used and practical equipment.Because the usually operation aloft of this equipment, thereby its safety in utilization just seems particularly important.The electronic integral hoisting scaffold of extensive use in high-building construction at present, the anti-drop system in its Lifting and lowering for scaffold have polytypes such as the single direction ratchet of employing formula, two-way ratchet friction-type, clamp-type, the anti-faller of FSZ-1 type and pulley type catching device.But generally there are defectives such as complex structure or security performance be bad in above-mentioned anti-drop system.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of anti-drop system that is used for the hydraulic climbing formwork system safe and simple in structure.
Anti-drop system is the operating mechanism of hydraulic climbing formwork system, and it climbs and the safety guard of duration of work especially, and safety is its life.In order to solve the problems of the technologies described above, the utility model has adopted following technical proposals: this anti-drop system is made up of the catching device of two mechanical type snap actions.
This anti-drop system key mechanism that realization is climbed as the hydraulic climbing formwork system possesses following function:
1, one-way movement, the anti-drop system freely-movable that can make progress is so that creeping formwork rises smoothly;
2, adhere to continuously, anti-drop system is all the time attached on the guide rail;
3, dual security protection, whole anti-drop system is made up of two catching devices, forms dual security protection;
4, guarantee that hydraulic jack is in the axially loaded state all the time;
5, there is the checkout gear that reflects the safety dropping prevent mechanism duty in attachment state feedback, for control system provides information needed in the anti-drop system;
6, device is reasonable, compliance is strong, simple to operate, easy to maintenance, safe and reliable, light and handy.
Description of drawings
Fig. 1 is the structural representation of anti-drop system of the present utility model.
Fig. 2 is the internal construction schematic diagram of catching device shown in Figure 1.
Fig. 3 is the shell vertical view of catching device.
The specific embodiment
As shown in Figure 1: anti-drop system of the present utility model comprises two catching devices 1 and a hydraulic jack 2, these two catching devices 1 bond attached on the guide rail 3, and by hydraulic jack 2 connections, described guide rail 3 is being provided with guide rail bayonet socket 31 every certain distance, thereby forms a cover anti-drop system.In order to realize that hydraulic jack is in the axially loaded state all the time, catching device adopts bearing pin 4 to connect with hydraulic jack.Last lower bearing pin is in quadrature, and catching device and hydraulic jack have just realized comprehensive hingedly like this, have guaranteed that hydraulic jack is in the axially loaded state all the time.As shown in Figure 2: described catching device 1 comprises: housing 11, and be located at voussoir 12, spring leaf 13 in the housing 11, be located at the outer spring base 14 of housing.Described voussoir 12 is rotatably connected by voussoir bearing pin 15 and housing 11, and an end of described spring leaf 13 is installed on the spring base 14, and the other end resilient abutment of described spring leaf is in the below of described voussoir.As shown in Figure 3, an end of described catching device 1 is provided with the guide groove 16 that is used to bond guide rail 3, and the shape of described guide groove matches with the guide rail shape, also is provided with travel switch 17 on the voussoir 12 of described catching device 1.
The operating principle of catching device is: before hydraulic climbing formwork climbs, the catching device up and down of anti-drop system all bonds on guide rail, and be seated on the guide rail bayonet socket by voussoir, prevent that hydraulic climbing formwork from falling downwards, as shown in Figure 2, when hydraulic climbing formwork climbs, cylinder is stretched on hydraulic pressure a thousand pieces of gold top, last catching device rises with hydraulic climbing formwork behind the stroke because the catching device constrained motion has one-way (downwards), therefore on catching device can not hinder hydraulic jack and stretch cylinder.But go up the spring of catching device in this course, make its voussoir be close to guide rail all the time upwards.Electromagnetic valve is under the domination of the control system of climbing synchronously, make the hydraulic oil commutation, hydraulic jack synthlipsis cylinder, last catching device is seated in (as shown in Figure 3) on the guide rail bayonet socket by voussoir, and assurance hydraulic climbing formwork system does not fall, and rests on the new high degree after climbing, following catching device then moves upward under the traction of hydraulic jack, behind the stroke, its voussoir is close to guide pass and is seated on the guide rail bayonet socket under spring action.Electromagnetic valve makes the hydraulic oil commutation under the domination of the control system of climbing synchronously.The hydraulic climbing formwork system enters the next one and climbs in the stroke.In the process of climbing, play a role all the time, guarantee that hydraulic climbing formwork is in a safe condition always with the inactive state anti-drop system.On the voussoir of catching device travel switch is installed, can reflects the duty of catching device, travel switch can in time provide the signal of catching device duty for control system.
