Description
Technical field
The utility model relates to a kind of fixture of construction implement, particularly belongs to a kind of fall protection equipment that is applicable to attachment type raise scaffold.
Background technology
Attachment type raise scaffold, as a kind of advanced auxiliary construction device high-rise, construction of super highrise building, the application on the building site is more and more universal.Compare with traditional console mode scaffold, overhanging scaffold, it is little that it has an area occupied, advantages such as economical with materials.But because its application time is shorter, product is still perfect not to the utmost, and at present there is safety defect in various degree in design in the product of using, and wherein Zui Da potential safety hazard is the support body problem of falling; Though occurred multiple fall arrest utensil at present, still there are many incomplete places at design aspect, simple and crude as structure, delay of response, even malfunctioning, failure phenomenon can take place, serious harm constructor's life security.
The utility model content
The purpose of this utility model is to provide a kind of novel attaching scaffold multi-functional anti-drop device, to reach the purpose that property easy to use, safe is good, stability is high.
The multi-functional anti-drop device of attaching scaffold provided by the utility model comprises safety dropping prevent mechanism and scaffold guide rail, it is characterized in that, the scaffold guide rail body has back-up block towards a side of safety dropping prevent mechanism, by vertical, equidistantly arrangement in order; Described safety dropping prevent mechanism comprises supportive body, synchronizing wheel, speed differential brake and manually shores; The speed differential brake comprises brake axle, quiet fluted disc and active toothed disk; Screw thread is arranged on the brake axle, and an end is provided with shoulder block; Quiet fluted disc is sleeved on the position of close shoulder block on the brake axle, is matched in clearance between centre bore and the brake axle; The centre bore of active toothed disk has screw thread, with the threaded engagement on the brake axle; Corresponding radial tooth and teeth groove are arranged on quiet fluted disc and the active toothed disk card in opposite directions; Synchronizing wheel is a gear, fixedlys connected with the brake axle of speed differential brake, and its tooth pitch is corresponding with the spacing of scaffold guide rail upper support piece; Manually shore by spring action and be close to the scaffold guide rail.
The multi-functional anti-drop device of attaching scaffold provided by the utility model, in use, safety dropping prevent mechanism is fixed on the outer side elevation of building by supportive body, wherein, synchronizing wheel rotates along with the lifting of main frame guide rail, and the speed differential brake is by the decrease speed of synchronizing wheel monitoring main frame guide rail.Manually shore and depend on swing in real time when the scaffold guide rail rises, when the stop motion of scaffold guide rail or when descending, manually shore the back-up block below that is stuck in the scaffold guide rail, restriction scaffold guide rail moves downward, and with the support body weight transmitting to building; When emergency situations produces, when the effect of manually shoring was lost efficacy, the decrease speed of scaffold guide rail increased, and synchronizing wheel drives the brake axle fast rotational of speed differential brake, active toothed disk is because of the effect of inertia rotation that lags behind, and produce relative motion between the brake axle, because of threaded function near quiet fluted disc and being engaged with, abut against on the shoulder block of brake axle, all rotations stop, synchronizing wheel is braked, the gear teeth of synchronizing wheel are stuck between the back-up block, thereby make the scaffold guide rail stop to descend.This shows the good effect that the utlity model has multiple anti-fall measure, be quick on the draw, security performance is good, stability is high.
Description of drawings
Accompanying drawing partly discloses specific embodiment of the utility model, wherein,
Fig. 1, the utility model elevation;
Fig. 2, the utility model right side view;
Fig. 3, the safety dropping prevent mechanism structural representation;
Fig. 4, synchronizing wheel and speed differential brake assembling schematic diagram.
The specific embodiment
As shown in Figure 1 and Figure 2, the multi-functional anti-drop device of attaching scaffold provided by the utility model comprises safety dropping prevent mechanism and scaffold guide rail 1, and described safety dropping prevent mechanism comprises supportive body 4, synchronizing wheel 7, speed differential brake 9 and manually shores 2.Safety dropping prevent mechanism is fixed on the outer side elevation of building by supportive body.Have leading arm 5 on the safety dropping prevent mechanism, the anti-tip wheel 6 that fits together with leading arm is stuck in the I shape steel tank of scaffold guide rail 1, and the direction so that fixedly the scaffold guide rail moves also can prevent that the scaffold guide rail breaks away from the restriction of safety dropping prevent mechanism simultaneously.
As shown in Figure 3, synchronizing wheel 7 is a gear, and its tooth pitch is corresponding with the distance between the scaffold guide rail adjacent supports piece, and the two formation is similar to the cooperation of wheel and rack.Manually shore and under the effect of spring 8, be close to the scaffold guide rail, when rising, depends on the scaffold guide rail swing in real time, when the stop motion of scaffold guide rail or decline, manually shore and be stuck in the back-up block below, and support body weight is delivered on the building by the scaffold guide rail, play support, anti-fall effect.
As shown in Figure 4, synchronizing wheel 7 is fixedlyed connected with the brake axle 9-1 of speed differential brake; Described speed differential brake has screw thread on its brake axle, and quiet fluted disc 9-2 is fixed on the safety dropping prevent mechanism main body, is in the transfixion state, is matched in clearance between its centre bore and the brake axle.Active toothed disk 9-3 by thread set on brake axle.Have spacing between quiet fluted disc and the active toothed disk and keep spring 9-4.When brake axle normally rotates, because spacing keeps the effect of spring, can not mesh because there being spacing between quiet fluted disc and the active toothed disk; When brake axle accelerates to rotate suddenly, active toothed disk moves to quiet fluted disc under the effect of inertia and screw thread, overcome the elastic force that spacing keeps spring, with quiet fluted disc engagement, and because the existence of shoulder block, active toothed disk compresses quiet fluted disc, thereby the brake axle rotation is stopped, synchronizing wheel also thereby stop rotation, its gear teeth are stuck between the back-up block, and then the scaffold guide rail is stopped falling.
In addition, as shown in Figure 1 and Figure 2, supportive body 4 is provided with suspension ring 3, as with power hoisting device or the loop chain part that is connected with building.
