Abstract
The utility model relates to a broken wire fall-preventing device for vertical transport vehicles, which is suitable for various vertical transport machines. When a steel cable is broken suddenly, the broken wire fall-preventing device for vertical transport vehicles can be supported by a pulley; with the help of a connecting rope, a triangular bracket, an extension spring, and a safety hook, the vertical transport machinery can be stopped sliding in order to avoid personal casualties and an economic losses. The utility model has the advantages of quick and reliable braking, convenient installation and maintenance, and low manufacture cost.
Description
The utility model relates to the safety guard that the disconnected rope of hanging scaffold falls that prevents of a kind of building and installation machinery, particularly gantry frame type gig.
In building and installation industry, the use of vertical transport machine is more extensive.Because this equipment lacks the failure-free anti-fall device, the high-altitude falling accident that causes the disconnected rope of hanging scaffold to cause happens occasionally.There are several shortcomings respectively in several disconnected rope anti-fall device that uses at present: at first, discharge when utilizing disconnected the rope and can cause hanging scaffold both sides ejection quarter butt to go deep in the frame structure, this structural impact power is big, support body is impaired serious, and when hanging scaffold Loaded goods centre-of gravity shift, the hanging scaffold of tenesmus can produce instantaneous rotation, cause latch to tilt and can not place abreast frame in horizontal support on, and lose anti-fall effect.The lever that affects by brute spring when another kind is disconnected rope is pressed into the contract piece makes the hanging scaffold braking, if this structure long-term use, guide rail will be out of shape, and its spacing is changed differ and loses anti-fall effect.The friction-type structure is because due to operating environment and the friction material, effect can degenerate gradually, loses anti-fall effect at last.These several complex structures are made difficulty, also are not easy to installation and maintenance, and cost is higher.
The purpose of this utility model provides a kind of simple in structure, and is easy to manufacture, do not damage support body and guide rail, the disconnected rope of vertical transport machine applied widely anti-fall device.
The purpose of this utility model realizes by following measure:
Be fixed with pulley at traditional hanging scaffold crossbeam middle part and prop up arm seat, fix a pulley support arm that can rotate around this pivot pin with pivot pin respectively at two ends, the left and right sides that pulley props up arm seat, the other end of this pulley support arm supports pulley with pivot pin fixed installation one, its outside be equipped with one with the U type shifting ring of this pulley coaxle.Steel rope will support pulley through two simultaneously.Two ends at the hanging scaffold crossbeam are fixed with the hook with safety tong bearing again respectively, and the top of each hook with safety tong bearing is fixed two can be around its fixing hook with safety tong of rotating of pivot pin, and two hook with safety tong back sides connect into a black box with two fixed links.Former support body inboard has only horizontal support and strengthens at its two ends.Three supporting legs of A-frame are captiveed joint with fixed link, and its top point is connected by steel rope with shifting ring; In addition, the top point of A-frame also is connected with extension spring, and the other end of spring is captiveed joint with the spring support plate that is fixed on hanging scaffold crossbeam two ends.In addition, the angle of inclination of a support arm limiting stopper with restriction pulley support arm is installed between pulley support arm and hanging scaffold crossbeam.
When vertical transport machine normal operation, owing to the effect of steel rope makes two to support pulleys and slope inwardly respectively, hook with safety tong is also inwardly drawn simultaneously respectively leave support body and support pulling force that pulley overcomes extension spring by connection cord and A-frame respectively, this moment sinking stage's elevation and subsidence freely.Steel rope supports the effect that pulley loses external force immediately in case broken, together with hook with safety tong under the effect of extension spring power; pull to support body; at this moment hook with safety tong hangs in the horizontal support of support body inboard firmly, and has stoped hanging scaffold to fall, and plays and resolves the rope protective effect.
The utility model compared with prior art has the following advantages:
This apparatus structure is simple, and braking is reliable, does not damage support body and guide rail, is not subjected to the restriction of support body and guide rail form, is widely used, and manufacture, installation, maintenance are convenient, and cost is low.
The drawing of accompanying drawing is described as follows:
Fig. 1 is a structural representation of the present utility model
Fig. 2 is the birds-eye view of Fig. 1
Below with reference to drawings and Examples the utility model is further described:
Referring to accompanying drawing 1, shown in 2, the disconnected rope of vertical transport machine put fall device mainly by hook with safety tong assembly, pulley support arm 11, support arm limiting stopper 12, support pulley 10, shifting ring 9, hanging scaffold and support body etc. and form, wherein, the hook with safety tong assembly is made up of hook with safety tong 1, fixed link 2, A-frame 3, extension spring 4, spring support plate 5 and hook with safety tong bearing 7.On the center of existing hanging scaffold crossbeam 15, be fixed with the pulley that is welded into steel plate and prop up arm seat 14, all using pivot pin 13 to fix one in its every side can be around the pulley support arm 11 of this pivot pin rotation, the other end of this pulley support arm 11 is installed one and is supported pulley 10, and a U type shifting ring 9 coaxial with this pulley 10 is equipped with in its outside.Connection cord 8 is connected with the A-frame 3 that is welded into round steel, fixed link 2 weld togethers at hook-type hook with safety tong 1 back side that three supporting legs of A-frame 3 and steel plate are made, hook with safety tong 1 usefulness pivot pin 6 are fixed on the hook with safety tong bearing 7 that is welded into steel plate and can rotate around pivot pin 6.Hook with safety tong bearing 7 is fixedly connected on the two ends of hanging scaffold crossbeam 15, and the spring support plate 5 of fixed length bar shaped is distinguished at its two ends again, and an end of spring support plate 5 is connected or clasp joint with extension spring 4, and the other end of extension spring 4 is connected with the intersection point of A-frame 3.
Behind disconnected rope, be fixed on the support arm limiting stopper 12 of the pulley support arm 14 of hanging scaffold crossbeam 15, to pulley support arm 11 support limit, make pulley support arm 11 and hanging scaffold crossbeam 15 angled, thereby also limited the angle of hook with safety tong 1 inclination support body 16.
When steel rope 17 makes the hanging scaffold normal operation by the pulling force that supports pulley 10 and overcome extension spring 4, pulley support arm 11 rotates to the center of pulley support arm 14 simultaneously, drive connection cord 8, A-frame 3, hook with safety tong 1 disengaging support body 16, sinking stage's elevation and subsidence freely at this moment.When steel rope 17 disconnects suddenly, support pulley 10 no external force effects, pulley support arm 11 rotates under the tension of extension spring 4, A-frame 3, hook with safety tong 1 are simultaneously to support body 16 motions, this moment, hook with safety tong 1 hung in the horizontal support of support body 16 inboards, and support body 16 inboards have only the horizontal support by certain distance.But for gaining in strength, two ends will be strengthened with angle steel.
