Description
Technical field:
The utility model relates to a kind of instrument, particularly relates to the total limit switch special tool of a kind of building hoist, belongs to safe construction accessory appliances technical field.
Background technology:
In recent years, along with the continuous increase of building height, the demand of the building hoist that antenna height is large is also in continuous increase.In recent years, building hoist has roof fall accident to occur more, the generation of the safe and effective prevention roof fall accident of total limit switch energy, but total limit-switch positions many places are in car 2.3 meters of eminences, go to draw limit switch according to normal person's height, cannot timely and effectively operate.Building hoist can carry 10 people by the cage of load-carrying 1t at every turn and calculate, if contingency has an accident, that will be heavy losses, so very important absolutely.
Utility model content:
Technical problem to be solved in the utility model is: overcome prior art building hoist operating personal in work progress and cannot get at the problem of total limit switch, there is provided a kind of building hoist total limit switch special tool, be connected with cylinder lever connecting rod by hook ring, under emergency rating, operating personal hook ring is left behind total limit switch in time, guarantees the safety of building hoist.
The technical scheme that the utility model is taked for technical solution problem is:
The total limit switch special tool of a kind of building hoist, comprises hook ring, cylinder lever connecting rod and holds hook, and described hook ring and cylinder lever connecting rod hook together with weld together or screwed connection with holding; Described hook skin of holding is provided with insulation skid resistant course.
The diameter of described hook ring is 3cm, and the length of described cylinder lever connecting rod is 45 ~ 55cm.
Described shape of holding hook, for annular or for hook-type or be " U " font, conveniently grips and hangs.
Positive beneficial effect of the present utility model is as follows:
1, the distance between total limit switch and operating personal effectively shortens by the utility model, solves the problem that operating personal reaches total limit switch, guarantees the safety of building hoist.
2, by the utility model can elevator generation electrical accident always upstream or downstream time effectively cut off total limit switch, ensure the safe in operation of elevator.
3, the utility model is simple to operate, decreasing operating personal under emergency rating and leaves behind time of total limit switch, providing guarantee to processing in time during building hoist et out of order.
4, the utility model structure is simple, economic and practical, and practicality is stronger.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention:
Below in conjunction with the drawings and specific embodiments, the utility model is further explained and illustrate:
See Fig. 1, the total limit switch special tool of a kind of building hoist, comprises hook ring 1, cylinder lever connecting rod 2 and holds hook 3, hook ring 1 and cylinder lever connecting rod 2 with hold together with hook 3 weld together or screwed connection; Hook 3 skin that is in one's hands is provided with insulation skid resistant course 4.
Wherein: the diameter of hook ring 1 is 3cm, the length of cylinder lever connecting rod 2 is 45 ~ 55cm; The shape of holding hook 3, for annular or for hook-type or be " U " font, conveniently grips and hangs.
The utility model is simple to operate, decreases operating personal under emergency rating and leaves behind time of total limit switch, providing guarantee, having ensured the safe in operation of elevator to processing in time during building hoist et out of order.
