Abstract
The invention discloses a displacement restrictor of roof caving resistance for various lifting systems, comprising a contact component, a protective cover, a fixing seat, a balancing lever, a steel wire rope and a heavy hammer; the contact component is fixed inside the protective cover which is fixedly arranged on the fixing seat; one side of the contact component is provided with a rotating rod which extends out of the protective cover and the rotating rod is fixed with the balancing lever; the heavy hammer is hung beneath the balancing lever through the steel wire rope. The device is simple in structure, practical, and convenient in installation and adjustment.
Description
Technical field
The present invention relates to a kind of control setup that all kinds of jacking systems promote the limit that is used for, refer to a kind of roof failure preventing position limiter especially.
Background technology
In all kinds of jacking systems, roof fall accident takes place in weight sometimes in lifting process, therefore generally all needs to install limiting device on the equipment girder steel.Traditional limiting device generally is by manually controlling, and takes place out of controlly sometimes, causes equipment damage and personal injury accident.
Summary of the invention
Accident occurs for fear of limiting device when out of control, cause equipment damage and personal injury, the invention provides a kind of roof failure preventing position limiter, personal safety is guaranteed in the safety when its purpose is the use of raising equipment.
A kind of roof failure preventing position limiter provided by the invention is made up of contactless switch parts, protective cover, permanent seat, weighted lever, weight, steel rope, and described contactless switch parts are fixed in the protective cover, and protective cover is fixedly installed on the permanent seat; One side of contactless switch parts is provided with bull stick, and it is outer fastening with weighted lever that this bull stick stretches out protective cover, and described weight hangs on below the weighted lever by steel rope.
Be connected with twine guide plate on the described weight, the twine guide plate edge is provided with guide hole.
Described permanent seat and weighted lever are fixedly installed on the equipment girder steel.
Use when of the present invention, when the weight lifting process reached constrain height, weight was drawn over to one's side a basket shake-up weight, acts on the contactless switch parts by weighted lever, makes device powers down, avoids causing roof fall accident.
Advantage of the present invention is: simple in structure, practicality is installed easy to adjust.
Description of drawings
Fig. 1 is the structural representation of roof failure preventing position limiter of the present invention.
Fig. 2 is the birds-eye view of Fig. 1.
Among the figure: 1. contactless switch parts, 2. protective cover, 3. permanent seat, 4. weighted lever, 5. bull stick, 6. steel rope, 7. weight, 8. twine guide plate is 9. hung steel rope, 10. equipment girder steel, 11. conductor rope supports, 12. conductor rope covers, 13. draw over to one's side basket
The specific embodiment
Fig. 1, Fig. 2 are the structural representations of roof failure preventing position limiter embodiment.The contactless switch parts 1 of roof failure preventing position limiter are fixed in the protective cover 2, one side of contactless switch parts 1 is provided with bull stick 5, this bull stick 5 stretches out protective cover 2 outer and weighted levers 4 fastening (weight is welded on the lever on the weighted lever), and weight 7 hangs on weighted lever 4 belows by steel rope 6; Twine guide plate 8 is housed on the weight 7, and the twine guide plate edge is provided with guide hole.
Roof failure preventing position limiter of the present invention is installed in equipment usually and hangs near the steel rope 9.What the lower end of hanging steel rope 9 was hung with the carrying weight draws over to one's side basket 13, and these both sides of drawing over to one's side basket are provided with conductor rope support 11, and the conductor rope support is provided with conductor rope cover 12, and this conductor rope cover 12 is corresponding with the guide hole at twine guide plate 8 edges; The lower end of hanging steel rope 9 is passed conductor rope cover 12 and is drawn over to one's side baskets 13 and be connected.
During installation, the contactless switch parts 1 of roof failure preventing position limiter are fixed in the protective cover 2, stretch out protective cover 2 outer bull sticks 5 by the contactless switch parts and use screw in compression with weighted lever 4, then that steel rope 6 upper ends and weighted lever 4 are fixing, steel rope 6 lower ends and weight 7 are fixing.Permanent seat 3 related protective covers 2, weighted lever 4 together are fixedly installed in (as shown in Figure 1) on the equipment girder steel 10, the lower end of hanging steel rope 9 guide hole from twine guide plate 7 edges is passed, make steel rope 6 be adjusted to hang steel rope 9 parallel and guarantee to hang steel rope 9 be pass from guide hole center, twine guide plate 7 edge after, with the lower end of hanging steel rope 9 with draw over to one's side basket 13 frames on conductor rope on the conductor rope support 11 overlap 12 and be connected and get final product.
When using jacking equipment to promote weight; weight on the roof failure preventing position limiter 7 is hung on setting height; what carry weight draws over to one's side basket 13 in lifting process; when the conductor rope support 11 on drawing over to one's side basket 13 is collided with the twine guide plate 8 of weight 7; the steel rope 6 that hangs weight is lax, and the weighted lever 4 of steel rope 6 upper ends promptly is rotated down on bull stick 5, touches contactless switch parts 1; make the device power supply (DPS) outage, reach the preventive device purpose.
