The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in detail.
The utility model proposes at the safety precautions of vertical transport systems, and what relate to is the rail clamping device of emergency braking under the accident conditions.Rail clamping device is installed in the cage top, moves up and down with cage; During normal the operation, lifting rope tension force overcomes gripping power and does not brake; Initiation that lifting rope is disrumpent feelings clamps braking, and light requirement electrical signal conduction system does not rely on mechanical drive to realize clamping braking merely, does not need the driving of manpower, electric power or hydraulic power; Clamp in time reliable, cage to fall distance very short; Lifting rope recovers tension force can remove the clamping braking, does not need complicated brake off program.
As Figure 1-3, the support 1 that the lower end of rail clamping device is and the cage welding is fixed, the upper end is connected with lifting rope, and present embodiment is to be connected with lifting rope by pulley assembly, might not be confined to this kind form in actual applications certainly.Support 1 top is provided with spring perch 4, is provided with spring 9 in the spring perch 4, and the upper end of spring 9 is provided with gland 10, and the upper end of gland 10 is provided with regulating sleeve 6, and the outside of spring perch 4 upper end glands is provided with nut 5.A vertical pull bar 11 passes the spring 9 in the spring perch, the pull bar upper end can be designed to multi-form according to the type of attachment of lifting rope, pull bar 11 bottoms flexibly connect by standard attaching parts 13 with an end that is arranged on the horizontal lever 2 in the support 1, the other end of lever 2 connects two slide blocks 8 that are arranged in the baffle plate 12 by connecting rod 14, and baffle plate 12 is fixed on support 1 two ends by standard fasteners 3.Two groups of levers 2 about being provided with in the support 1, every group of lever all connects two slide blocks that are arranged in the baffle plate by connecting rod, forms the left-right symmetric structure.The outside of every slide block 8 is provided with wedge shape orienting lug 7, and lever 2 middle parts are provided with bearing pin, and lever rotates in perpendicular along the middle part bearing pin, thereby drives slide block 8 up-and-down movement in the inner chamber of wedge shape orienting lug 7 and baffle plate 12 formation; The vertical track 15 of jacking system passes two gaps between the slide block.The face that wedge shape orienting lug 7 contacts with slide block 8 is intilted inclined-plane from bottom to top; Two slide blocks 8 are during along wedge shape orienting lug 7 upward movements, and the horizontal throw between them reduces gradually, thereby clamps vertical track 15; Two slide blocks 8 are when wedge shape orienting lug 7 moves downward, and the horizontal throw between them increases gradually, discharges vertical track 15.Slide block 8 is provided with the laciniation that is used to increase friction force with the surface that vertical track 15 contacts.
In the present embodiment, the specific implementation form of two groups of lever constructions can be referring to Fig. 4, with the pull bar bonded assembly partly be single structure, with connecting rod and slide block bonded assembly partly be the double joint structure, connect by bearing pin between two parts, thereby realization drives the version of two slide block up-and-down movements simultaneously.
As shown in Figure 5, when vertically transport systems normally moves, lifting rope tension force and rail clamping device and cage are dead-weight balanced, spring force approximates the difference of lifting rope tension force and pull bar deadweight, spring is compressed by the degree of depth, spring length is determined draw rod positions, and draw rod positions is determined the angle of lever 2, and the lever angle determines the slide position by connecting rod.At this moment, homonymy two slide blocks 8 spacings should be greater than track 15 thickness, and arbitrary slide block and track all keep necessary gap.
As shown in Figure 6, when vertically the lifting rope of transport systems is disrumpent feelings, state of equilibrium during normal the operation is broken, and lifting rope tension force disappears, the weightless drop of whole moment of rail clamping device and cage, the abrupt release of spring section pressure, the drive pull bar moves down, and pull bar moves down and drives lever 2 rotations, and the lever rotation makes on the slide block 8 through the connecting rod transmission and moves, move on the slide block homonymy two slide block spacings are reduced, contact with track 15.At this moment, spring also leaves enough pressure, and this pressure conducts to slide block through pull bar, lever and connecting rod, form certain pressure at slide block and interorbital, pressure produces force of sliding friction, and friction force is far longer than rail clamping device and cage deadweight, makes cage stop rapidly falling.Because the time compole of rail clamping device reaction is short, the drag friction power of generation is bigger, can guarantee falling apart from less of cage, i.e. braking is reliable rapidly.
After lifting rope was repaired, system turned round again, made lifting rope recover tension force, and lifting rope tension force is compressed spring again, and pull bar is up, the lever rotation, and slide block moves down, and final slide block de-orbits the state of equilibrium when system recovery normally moves, state promptly shown in Figure 5.
Obviously, those skilled in the art can carry out various changes and modification to the utility model and not break away from spirit and scope of the present utility model.Like this, if of the present utility model these are revised and modification belongs within the scope of the utility model claim and equivalent technology thereof, then the utility model also is intended to comprise these changes and modification interior.
