Abstract
The utility model provides an elevator speed limiting device, comprising a rope wheel wound with a wire rope, a rope-pressing frame, and a rope-pressing block; the rope-pressing block is arranged on the rope-pressing frame through a rotary shaft; the rope wheel is arranged on a rope wheel shaft; two ends of the rope wheel shaft are arranged on a frame; the rope-pressing block matches the wire rope; the frame comprises two side plates; each side plate is fixed on a soleplate base by a bolt; two ends of the two side plates are respectively connected by a pin shaft; the pin shaft arranged on the left end of the two side plates are provided with the rope-pressing frame; the front surface and the back surface of the two side plates are arranged on one end of the pin shaft and are both symmetrically provided with a regulating bolt; two regulating bolts extend outward and pass through the side plates; the bolt heads respectively prop against the front end surface and the back end surface of the rope-pressing frame. The utility model aims at providing an elevator speed limiting device of reliable performances, being capable of limiting the speed of elevator declining at a super speed by electric signals or in a mechanical way.
Description
Technical field
The utility model relates to the safety device that a kind of elevator works when the irregular operating state, specifically relate to a kind of elevator governor of hypervelocity when preventing that elevator from descending.
Technical background
When the running velocity of elevator decline surpasses command speed; or during the traction steel wire fracture of rope of elevator; just need safety device in time system to be protected; to prevent unexpected the generation; existing velocity limiter normally utilizes rope sheave to rotate the centnifugal force that produces; by outage; mechanical brake device makes on its guide rail that rests on elevator the elevator brake that hypervelocity descends; but adopt thin plate to make the support of U type mostly owing to be used for the support of part such as supporting rope wheel shaft in the mechanical brake device; cause the rigidity of support relatively poor; rope guarding plate in the mechanical brake device does not have accurate location vertically and can not adjust; when the mechanical brake device of elevator governor carries out glancing impact; cause the support distortion that is distorted sometimes; while does not have accurate location vertically owing to rope guarding plate and can not adjust; rope guarding plate can't accurately be clamped steel rope; cause steel rope between rope sheave and rope guarding plate, to deviate from; not only fail to clamp steel rope; and can cause elevator governor to damage; especially stayed potential safety hazard for the higher elevator of speed, and to the normal operation of equipment.
The utility model content
The purpose of this utility model provides a kind of dependable performance, can carry out the elevator governor of electric signal and mechanical speed limit to the elevator that hypervelocity descends.
Elevator governor of the present utility model, comprise support, be wound with the rope sheave of steel rope, press rope support, cord-pressing block, cord-pressing block adopts rotating shaft to be installed in and presses on the rope support, described rope sheave is installed on the sheave shaft, the two ends of sheave shaft are rack-mount, described cord-pressing block matches with described steel rope, described support is made up of two side plates, two side plates are fixed on the bottom block in parallel to each other, the both sides of two side plates adopt bearing pin to link to each other respectively, the bearing pin that is positioned at two side plate left sides is equipped with described pressure rope support, an end of bearing pin was provided with a trimming screw separately symmetrically on the left of two side plate outsides were positioned at, two trimming screws are from passing side plate outside to inside, its screw head withstand on respectively press rope support before, on latter two end face.
Elevator governor of the present utility model, wherein each described side plate is the L type, the thickness of side plate is 4～10mm.
Elevator governor of the present utility model, the two ends of wherein said bearing pin adopt nut to be fixed on the described side plate.
The advantage of elevator governor of the present utility model is: its support comprises two side plates, each side plate adopts respectively and is bolted on the bottom block, the both sides of two side plates adopt bearing pin to link to each other respectively, improved the rigidity of support, the possibility that is distorted when having reduced support force and is out of shape, the bearing pin that is positioned at two side plate left sides simultaneously is equipped with the pressure rope support, the screw head of two trimming screws pass side plate withstand on respectively press rope support before, on the back both ends of the surface, can accurately locate along the axial position of rotating shaft cord-pressing block, make cord-pressing block can accurately clamp steel rope, avoid steel rope between rope sheave and cord-pressing block, to deviate from, so elevator governor dependable performance of the present utility model can be carried out electric signal and mechanical speed limit to the elevator that hypervelocity descends.
Below in conjunction with accompanying drawing elevator governor of the present utility model is described in further detail.
Description of drawings
Fig. 1 is the main pseudosection of the structural representation of elevator governor of the present utility model;
Fig. 2 is the lateral plan of Fig. 1.
The specific embodiment
By Fig. 1 and Fig. 2 as can be seen, elevator governor of the present utility model, comprise support, be wound with steel rope 1 rope sheave 2, press rope support 3, cord-pressing block 4, cord-pressing block 4 adopts rotating shaft 5 to be installed in and presses on the rope support 3, described rope sheave 2 is installed on the sheave shaft 6, the two ends of sheave shaft 6 are installed in rotation on the support, described cord-pressing block 4 and described rope sheave 2 and on steel rope 1 match, described support is made up of two side plates 7, two described side plates 7 are the L type, the thickness of side plate 7 is 6mm, also can be 4～10mm.Two side plates 7 adopt bolt to be fixed in parallel to each other on the bottom block 8, and the both sides of two side plates 7 adopt bearing pin 9 to link to each other respectively, and the two ends of described bearing pin 9 adopt nut to be fixed on the described side plate 7.The bearing pin 9 that is positioned at two side plate 7 left sides is equipped with described pressure rope support 3, an end of bearing pin 9 was provided with a trimming screw 10 separately symmetrically on the left of two side plate 7 outsides were positioned at, the screw head of two trimming screws 10 withstands on respectively on former and later two end faces of pressing rope support 3 from passing side plate 7 outside to inside.
Elevator governor of the present utility model is to elevator brake the time, adopting bearing pin 9 respectively because of the two ends of two side plates 7 links to each other, improved the rigidity of support, the possibility that is distorted when having reduced support force and is out of shape, be provided with a trimming screw 10 separately symmetrically on the side plate 7 of an end of bearing pin 9 on the left of two side plate 7 outsides are positioned at simultaneously, the screw head of two trimming screws 10 pass side plate withstand on respectively press rope support 3 before, on the back both ends of the surface, can accurately locate along rotating shaft 5 axial positions cord-pressing block 4, make cord-pressing block 4 can accurately clamp steel rope 1, avoid steel rope 1 between rope sheave 2 and cord-pressing block 4, to deviate from, so elevator governor dependable performance of the present utility model, can carry out electric signal and mechanical speed limit to the elevator that hypervelocity descends, elevator brake is made on its guide rail that rests on elevator.
Embodiment recited above is described preferred implementation of the present utility model, is not that design of the present utility model and scope are limited.The content that the utility model is asked for protection all is documented in claims.
