Abstract
The utility model discloses an anti-falling device of a lift type scaffold. The anti-falling device of the lift type scaffold cooperates with a lifting system, an anti-falling suspender system and a scaffold box to work together, and the scaffold box is provided with an operating rod, a drive rod, a jaw, a spring device, anti-falling wheels and skewed slots. By utilizing lever drive, at the moment of falling, the anti-falling wheels move along the skewed slots to hold an anti-falling suspender, so that accidents of injury to people due to rope breakage and object falling can be prevented effectively. The anti-falling device of the lift type scaffold is simple in structure and convenient to use and can be widely applied to construction scaffolds.
Description
Technical field
The utility model relates to the apparatus field of the raise scaffold that uses in a kind of building operations, specifically a kind of raise scaffold anti-drop device.
Background technology
At present, the scaffold that uses in high-building construction comprises that scaffold casing, motor, wire rope, pulley, lifting object consist of, pulley is fixed on the lifting suspension rod of scaffold casing, wire rope is walked around pulley, and an end is connected with lifting object, and the other end is on Electrical machinery cylinder.Although this scaffold is general; but there is unsafe factor; because when support body climbs operation; lack sensitivity, reliably directly protection prevents the device that lifting object falls; so lifting object tenesmus casualty accident often occurs; when motor was broken wire rope, this harm was larger especially, lacked the safety in utilization guarantee.
Summary of the invention
The purpose of this utility model is to provide a kind of can prevent that lifting object tenesmus from hurting sb.'s feelings, using the safe scaffold with anti-drop device.
For reaching above purpose, the technical scheme that the utility model adopts is: a kind of raise scaffold anti-drop device, cooperate jacking system, anti-fall boom system, the scaffold casing, the lifting suspension rod that the suspension hook of jacking system hooks the scaffold casing works together, gripper shoe at the scaffold casing is fixed with drive link, end at drive link is connected with action bars, one end of action bars is connecting the suspension hook of lifting gear, the other end at drive link withstands jaw, a side pressure system of withstanding at the quilt of jaw a spring assembly, the other end of jaw is set to rectangular slot, two anti-fall wheels stem for stem in the groove, the anti-fall wheel in the skewed slot that is enclosed within respectively gripper shoe.Described two skewed slots are symmetrical, and its lower end skewed slot length of side distance is the length of jaw rectangular slot, and upper end skewed slot limit short distance is the suspension rod width of anti-fall boom system.The suspension rod of described anti-fall boom system is located at two anti-fall centres of taking turns of scaffold casing, and the suspension rod of anti-fall boom system is fixed on wall.
The beneficial effects of the utility model are: compare with the scaffold of present use, because having increased anti-fall the wheel at skewed slot moves, become the chock shape with anti-fall suspension rod, has boosting function, guarantee anti-fall take turns and suspension rod between non-slip, can effectively prevent the generation of rope-breaking article pendant casualty accident, and simple in structure, easy to use, can be widely used in scaffold for building.
Description of drawings
Fig. 1 is the utility model structural plan schematic diagram.
The specific embodiment
For further the utility model being described in detail, be described by reference to the accompanying drawings embodiment, protection domain of the present utility model is not limited only to following instance, and all contents identical with the technical solution of the utility model or that be equal to all fall into the protection domain of the utility model.
With reference to accompanying drawing 1, a kind of raise scaffold anti-drop device, cooperate jacking system, anti-fall boom system, the scaffold casing, the lifting suspension rod 3 that the suspension hook 1 of jacking system hooks scaffold casing 2 works together, gripper shoe 12 at scaffold casing 2 is fixed with drive link 4, end at drive link 4 is connected with action bars 5, one end of action bars 5 is connecting the suspension hook 1 of lifting gear, the other end at drive link 4 withstands jaw 6, a side pressure system of being withstood at jaw 6 spring assembly 7, the other end of jaw 6 is set to rectangular slot 8, in the groove 8 stem for stem two anti-fallly take turns 9, anti-fallly take turns 9 and be enclosed within respectively in the skewed slot 10 of gripper shoe 12.Described two skewed slots 10 are symmetrical, and its lower end skewed slot 10 length of sides distance is the length of jaw rectangular slot 6, and skewed slot 10 limit short distances in upper end are suspension rod 11 width of anti-fall boom system.The suspension rod 11 of described anti-fall boom system is located at two anti-fall 9 the centres of taking turns of scaffold casing 2, and the suspension rod 11 of anti-fall boom system is fixed on wall.。
When suspension hook 1 chain occurs in lifting broke, the deadweight of action bars 4 made drive link 5 other end perks, removed the pressure to jaw 6.At this moment, jaw 6 is subject to the spring thrust of spring assembly 7, drives anti-fall 9 skewed slots 10 along gripper shoe 3 of taking turns and rises, embrace anti-fall suspension rod 11, since anti-fall take turns 9 with anti-fall suspension rod 11 between formation chock angle, scaffold casing 2 is not dropped, guarantee that scaffold casing 2 is in a safe condition.
Claims (3)
1. raise scaffold anti-drop device, cooperate jacking system, anti-fall boom system, the scaffold casing, the lifting suspension rod that the suspension hook of jacking system hooks the scaffold casing works together, it is characterized in that being fixed with drive link in the gripper shoe of scaffold casing, end at drive link is connected with action bars, one end of action bars is connecting the suspension hook of lifting gear, the other end at drive link withstands jaw, a side pressure system of withstanding at the quilt of jaw a spring assembly, the other end of jaw is set to rectangular slot, two anti-fall wheels stem for stem in the groove, the anti-fall wheel in the skewed slot that is enclosed within respectively gripper shoe.
2. a kind of raise scaffold anti-drop device according to claim 1 is characterized in that described two skewed slots for symmetrical, and its lower end skewed slot length of side distance is the length of jaw rectangular slot, and upper end skewed slot limit short distance is the suspension rod width of anti-fall boom system.
3. a kind of raise scaffold anti-drop device according to claim 1 it is characterized in that the suspension rod of described anti-fall boom system is located at two anti-fall centres of taking turns of scaffold casing, and the suspension rod of anti-fall boom system is fixed on wall.
