Abstract
The utility model relates to an anti-falling freight elevator with a machine room. The anti-falling freight elevator comprises a passenger car, a driving device and an anti-falling device, wherein the driving device is used for driving a car to move upward and downward, and the anti-falling device is arranged on the side wall of the car. The anti-falling device comprises a clamping part arranged on the side wall of the car, and an overspeed governor arranged in an elevator passageway and connected with the clamping part in a linkage manner, the clamping part comprises a chute, and two clamping blocks arranged in the chute in a sliding way, and the clamping blocks are connected with the overspeed governor in the linkage manner. The anti-falling freight elevator has a simple structure, when the car is out of control and falls down, the overspeed of the anti-falling freight elevator triggers the overspeed governor to work so as to enable steel wires to stop moving, a lifting arm is enabled to lift the clamping blocks, and the clamping blocks clamp a guide rail so as to prevent an elevator from continuously falling down. The anti-falling freight elevator is provided with higher sensibility and safety.

Background technology
Along with economic development, life and work rhythm is accelerated, and elevator more and more is widely used in the skyscraper, and the elevator safety problem also more and more causes people's attention.Existing elevator car safety complex structure, the triggering that makes its safety device is complicated also, therefore can't start timely and effectively the installation anti-fall device when elevator is out of control, has buried potential safety hazard for the operation of elevator.
Summary of the invention
The utility model purpose provides a kind of anti-fall machine room Cargo Lift that has.
In order to achieve the above object, the technical scheme that the utility model adopts is: a kind of anti-fall machine room Cargo Lift that has, it comprises the elevator car, be used for to drive the actuating device of car up-and-down movement, the anti-fall device on being arranged on the sidewall of car, the velocity limiter that described anti-fall device comprises the clamping section that is fixedly installed on the car side wall, be arranged in the access to elevators and link and be connected with the clamping section, described clamping section comprises chute, two clamps that are slidingly arranged in the chute, and described clamp and velocity limiter are connected.
Described velocity limiter is the friction-type centrifugal velocity limiter, it comprises frame, steel rope, the lift arm that is fixedly connected with steel rope, be rotatably connected on the rope sheave on the frame, the slipper that rotates and be connected and be positioned at rope sheave top with described frame, be provided with the block that agrees with mutually with slipper one end on the described rope sheave end face, described rope sheave outer ring evenly is provided with the cambered surface of a plurality of projections, the other end of described slipper is rotationally connected and roller, described roller is connected with described rope sheave friction of rolling, and described lift arm one end and the steel rope other end that is fixedly connected is connected with the clamp bottom.
Described chute comprises a left side half groove and right half groove of symmetrical setting, and a described left side half groove and right half groove are echelon form, and two described clamps are two symmetrical right-angled trapezium pieces that are arranged in the chute.
Two described clamps are provided with for the striped that increases friction on the relative side.
Owing to adopt technique scheme, the utlity model has following advantage: the utility model is simple in structure, when car tenesmus out of control, its excessive velocities can trigger velocity limiter work and make the steel rope stop motion, and then lift arm is promoted clamp, thereby described clamp clamping guide-rail prevents elevator and continues tenesmus that the utility model sensitivity is higher, has higher safety.

The specific embodiment
Below in conjunction with accompanying drawing, the preferred specific embodiment of the utility model is described.
This is anti-fall a machine room Cargo Lift, and it comprises elevator car 3, be used for driving the actuating device 2 of car 3 up-and-down movements, the anti-fall device 4 on being arranged on the sidewall of car 3.
The velocity limiter 42 that described anti-fall device 4 comprises the clamping section 41 that is fixedly installed on car 3 sidewalls, be arranged in the access to elevators and link and be connected with clamping section 41.
Described clamping section 41 comprises chute 411, two clamps 412 that are slidingly arranged in the chute 411, and described clamp 412 is connected with velocity limiter 42.Described chute 411 comprises a left side half groove 413 and right half groove 414 of symmetrical setting, and a described left side half groove 413 is echelon form with right half groove 414, and two described clamps 412 are two symmetrical right-angled trapezium pieces that are arranged in the chute 411.Two described clamps 412 are provided with for the striped that increases friction on the relative side.
Described velocity limiter 42 is the friction-type centrifugal velocity limiter, it comprises the frame 422 that is fixed in the access to elevators, the lift arm 428 that is fixedly connected with steel rope 424, be rotatably connected on the rope sheave 421 on the frame 422, the steel rope 424 of winding on rope sheave 421, the slipper 423 that rotates and be connected and be positioned at rope sheave 421 tops with described frame 422, be provided with the block 425 that agrees with mutually with slipper 423 1 ends on described rope sheave 421 end faces, described rope sheave 421 outer rings evenly are provided with the cambered surface 426 of a plurality of projections, the other end of described slipper 423 is rotationally connected and roller 427, described roller 427 is connected with described rope sheave 421 friction of rollings, and described lift arm 428 1 ends and steel rope 424 other end that is fixedly connected is connected with clamp 412 bottoms.
When car 3 tenesmus out of control, its excessive velocities causes rope sheave 421 rotating speeds too fast, slipper 423 amplitudes of fluctuation increase, slipper 423 can be pushed against rope sheave 421 is stopped operating, because friction, also stop motion of steel rope 424 on the rope sheave 421, and then lift arm 428 is promoted clamp 412, thereby preventing elevator, described clamp 412 clamping guide-rails 5 continue tenesmus.
