Abstract
The utility model relates to a drill tower security facility, in particular to a falling resistant device of a drill tower elevator. The falling resistant device of the drill tower elevator comprises two sets of lever-type wedge block falling resistant mechanisms symmetrically arranged on two sides of an elevator compartment. Each lever-type wedge block falling resistant mechanism comprises a rigidity rod, the middle of the rigidity rod is hinged with the top of the compartment, one end of the rigidity rod is connected with an elevator steel cable, the other end of the rigidity rod is hinged with a vertical draw rod, and a restoring spring is sleeved on the external diameter of the vertical draw rod. A big-end-down wedge block is arranged at the tail end of the draw rod, the outer vertical face of the wedge block is attached closely to an elevator guide rail, the inner vertical face of the wedge block is slidably matched with a fixing block, and the fixing block is fixed on the lateral face of compartment. The drill tower elevator utilizes the falling resistant device matched with the wedge block, and the wedge block is utilized to be matched with the fixing block of the elevator compartment to produce friction with the guide rail, thereby realizing a movement. Under a condition that the compartment is not pulled by a steel wire rope, the more the elevator moves downwards, the tighter the wedge-shaped face is matched, and the friction between the wedge block and the guide rail is larger, thereby realizing a brake.
Description
[technical field]
The utility model relates to a kind of boring tower security facility, is specifically related to a kind of boring tower elevator falling proof device.
[background technology]
The jacking system that the tradition boring tower is disposed mainly is divided into two kinds.First kind is original hand pulling type jacking system, and this device at first will solve the counterweight problem, secondly is to lean on staff's stay cord could realize lifting action, uses time-consuming, effort, and brake gear operates cumbersome, and is handling not strong.Second kind is that Motorized lift device is the boring tower elevator, the control handle of this jacking system is to adopt the mode that line control is arranged, be that jacking system will be with the upper and lower motion of live wire in the process of work, owing to lack safety protection device, in case wirerope fracture, boring tower the staff just be in peril of one's life, so there is big potential safety hazard in this Motorized lift device.
[utility model content]
Technical problem to be solved in the utility model is to provide a kind of boring tower elevator falling proof device, and anti-fall dependable performance has improved boring tower staff's personal safety greatly.
The technical solution of the utility model is: boring tower elevator falling proof device, comprise that two covers are symmetricly set in the lever voussoir anti-falling mechanism of lift car both sides, described lever voussoir anti-falling mechanism comprises a rigid rod, described rigid rod middle part is hinged with described car top, described rigid rod one end is connected with elevator wire rope, and it is hinged that the other end and external diameter are with the vertical connecting rod of retracing spring; Described pull bar end is provided with a wedge type block that is up-narrow and down-wide shape, and the outer facade of described wedge type block is close to cage guide, facade and a positioning block bearing fit in the described wedge type block, and described locating piece is fixed in described car side.
Characteristics of the present utility model are: the falling proof device that the boring tower elevator adopts wedge to cooperate, utilize wedge to cooperate to produce friction between the locating piece of lift car and guide rail and realize action; At steel rope car is not had under the situation of pulling force, elevator moves downward more, and lozenges cooperates tight more, and the friction force between wedge and guide rail is big more, realizes brake.The falling proof device of this structure is reliable, and is simple in structure, improved staff's personal safety widely.
[description of drawings]
The utility model will be further described in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 be among Fig. 1 A to constructional drawing.
Among the figure: 1. rigid rod; 2.D shape button; 3. vertical connecting rod; 4. spring; 5. otic placode; 6. car; 7. wedge; 8. elevator roller; 9. locating piece; 10. brake band.
[specific embodiment]
Referring to Fig. 1, Fig. 2, boring tower elevator falling proof device, comprise that two covers are symmetricly set in the lever voussoir anti-falling mechanism of lift car both sides, described lever voussoir anti-falling mechanism comprises rigid rod 1, rigid rod 1 middle part and car 6 tops are hinged, rigid rod 1 one ends are connected with elevator wire rope by D shape button 2, and it is hinged that the other end and external diameter are with the vertical connecting rod 3 of retracing spring 4; Vertical connecting rod 3 ends are provided with a wedge type block 7 that is up-narrow and down-wide shape, and wedge type block 7 outer facades are close to cage guide, and facades and have locating piece 9 bearing fits of inclined surface in the wedge type block 7, and locating piece 9 is fixed in car 6 sides.
Be connected with brake band 10 between wedge type block 7 and the otic placode 5.
Concrete principle of work: elevator roller 8 is stuck in the track, and elevator roller 8 is connected with car 6 by otic placode 5, and the steel rope of pulling elevator and two D shape buttons 2 are fixing, realizes rising and descending thereby drive whole elevator.When elevator rises, carry on the steel rope, drive two D shapes and unload 2 button upward movements, rigid rod 1 is detained 2 coupling end upward movements with D shape, according to lever principle, the other end of rigid rod 1 drives pull bar 3 and moves down, pull bar 3 and wedge 7 spin by screw thread, and spring 4 is housed on the external diameter of pull bar 3, and this process medi-spring 4 is in compressive state, do not contact between wedge 7 and the track, thereby realize the elevator vertical motion.
When steel rope was transferred, because elevator itself and people's weight, rigid rod 1 and D shape were detained 2 coupling ends and still are in and carry the position, do not contact between wedge 7 and the track, thus the realization down maneuver.
When detaining 2 bonded assembly steel ropes and disconnect suddenly with D shape, anti-drop system starts, be specially: elevator loses pulling force upwards, and spring 4 loses balancing force upwards suddenly owing to be in compressive state in the process that rises before always, spring 4 can flick immediately, pull bar 31 is being with on the wedge 7 is moved, when the inclined-plane and the inclined-plane of locating piece 9 of wedge 7, when brake band 10 all contacts with guide pass, under the cooperation on two inclined-planes, elevator is realized brake function by locked.
Although illustrated and described embodiment of the present utility model, for the ordinary skill in the art, be appreciated that under the situation that does not break away from principle of the present utility model and spirit and can carry out multiple variation, modification, replacement and modification to these embodiment, scope of the present utility model is limited by claims and equivalent thereof.
