Abstract
The invention discloses a safety tongs linkage mechanism for an elevator. The elevator comprises a cabin and a cabin guide rail, wherein a speed limiter is arranged above the cabin; and the speed limiter is connected with the cabin through a speed limiter rope. The safety tongs linkage mechanism is characterized by comprising a pivot rod which is connected with a cabin pivot; a brake device which is pressed against the cabin guide rail is respectively arranged at two ends of the pivot rod; a first connecting rod vertical to the pivot rod is arranged in the middle of the pivot rod; and the first connecting rod is connected with two ends of the speed limiter rope. The safety tongs linkage mechanism realizes the brake function by using the speed-limiting function of the speed limiter after the brake device with a simple structure is annularly connected with the speed limiter rope, and has the advantages of simple structure, low cost, safety, reliability and the like.
Description
Technical field
The present invention relates to a kind of safety tongs interlinked mechanism that is used for elevator.
Background technology
As everyone knows, hoist ropes formula elevator comprises car and car guide rail, and car can move up and down along car guide rail.The situations such as suspension apparatus appearance fracture that do not prevent elevator cause the car hypervelocity to fall, and elevator also is equipped with emergency braking apparatus.Emergency braking apparatus generally comprises velocity limiter and safety tongs.Velocity limiter is normally to utilize action of centrifugal force, when rotating speed surpassed default value, velocity limiter can be braked the governor rope of walking around velocity limiter, and governor rope then starts safety tongs, make it rapidly lift car to be braked on car guide rail, thus assurance personnel and device security.Traditional safety tongs comprises polytypes such as hydraulic braking, electrodynamic braking or aerobraking.There is general defective in it, i.e. installation is complicated, reliability is low.Therefore the building industry sign JG-1996 of China is forbidden these brake mode.What generally all adopt at present is the mode of physics braking.As disclosing a kind of type mechanism of carving in the Chinese patent 02260471.5, brake in the mode of mechanical braking.But all structure is complicated usually for common being seen physics stop mechanism at present, and part is many, and the cost of therefore making and installing is higher.
Summary of the invention
The invention provides a kind of solution of the above problems, a kind of simple in structure, safe and practical safety tongs interlinked mechanism is provided.
Technical scheme of the present invention provides a kind of safety tongs interlinked mechanism that is used for elevator, described elevator comprises car and car guide rail, described car top also is provided with velocity limiter, described velocity limiter is connected with described car by governor rope, it is characterized in that: it comprises the pivoting lever with described car pivotal joint, described pivoting lever two ends be provided with described car guide rail against brake equipment, described pivoting lever middle part is provided with the head rod perpendicular to described pivoting lever, and described head rod is connected with the two ends of described governor rope.
Preferably, described pivoting lever two ends are provided with second pipe link perpendicular to described pivoting lever, and described second pipe link and described brake equipment flexibly connect.
Preferably, described brake equipment comprises that the vertical section is first slipper of U-shaped, described car guide rail inlay card is in the U-lag of described first slipper, also be movably set with second slipper of strip shape between the sidewall of the U-lag of described first slipper and the described car guide rail, described second slipper is provided with the bevelled groove, described first slipper is provided with the bolt that at least one passes described groove, described second slipper and the described second pipe link pivotal joint.
Preferably, described head rod is provided with brake-applying handle upwards.
Safety tongs interlinked mechanism of the present invention links to each other with the governor rope annular by a brake equipment simple in structure, utilizes the function of the speed limit function realization braking of velocity limiter.Have simple in structure, cost is low and advantage such as safe and reliable.
Description of drawings
Fig. 1 is the structural representation of safety tongs interlinked mechanism of the present invention.
The specific embodiment
Below the specific embodiment of the present invention is described in further detail.
As shown in Figure 1, safety tongs interlinked mechanism of the present invention comprises and the pivoting lever 10 of car (not shown) pivotal joint that pivoting lever 10 two ends are provided with second pipe link 12 perpendicular with the axis of pivoting lever 10.Second pipe link 12 is connected with brake equipment 14.Brake equipment 14 comprises that the vertical section is that first slipper, 16, the first slipper 16 of U-shaped wrap up car guide rail (not shown).Also be provided with second slipper 18 in the U-lag of first slipper 16.Second slipper 18 is strip shapes, it and second pipe link, 12 pivotal joints.Being provided with 20, two bolts 22 of a bevelled groove in the middle of second slipper 18 passes groove 20 second slipper 18 is connected on first slipper 16.Car guide rail is stuck between the sidewall and second slipper 18 of U-lag of first slipper 16, and groove 20 is upwards drawn close to car guide rail gradually.Pivoting lever 10 middle parts also are provided with the head rod 24 perpendicular with the axis of pivoting lever 10.Head rod 24 all is connected with the two ends of governor rope 26, and governor rope 26 is circularized.Also be provided with on the head rod 24 upwards and perpendicular to the brake-applying handle 28 of head rod 24.
The elevator that uses safety tongs interlinked mechanism of the present invention in use, velocity limiter is fixed on the top of elevator, governor rope 26 is walked around velocity limiter, forms an annular, its two ends link to each other with head rod 24 respectively.When elevator normally moved, slipper drove the governor rope 26 speed operation identical with lift car.In case phenomenons such as out of control occur moving, when causing the lift car hypervelocity to glide, velocity limiter is at first braked governor rope 26, the governor rope 26 of head rod 24 tops and head rod 24 formation is relatively moved, thereby upwards spur head rod 24.Head rod 24 drives pivoting lever 10 and rotates, and upwards carries second slipper 18 thereby drive second pipe link 12, second slipper 18 is made progress along groove 20 directions move relative to first slipper 16.Therefore gap smaller between the inwall of first slipper 16 and second slipper 18 can push car guide rail, thereby rubs the car stop with its generation.Equally, upwards spurring brake-applying handle 28 also can be with the car stop.
Above embodiment only is the present invention's a kind of embodiment wherein, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to claim of the present invention.Should be pointed out that for the person of ordinary skill of the art without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
