Abstract
The speed limiter tensioning device of the elevator comprises a sliding guide sleeve, a tensioning slide block, a rotating shaft and a tensioning wheel, wherein the sliding guide sleeve extends in the vertical direction, the tensioning slide block is arranged in the sliding guide sleeve, one end of the rotating shaft is connected with the tensioning slide block, the tensioning wheel is sleeved on the rotating shaft, the tensioning slide block is matched with the sliding guide sleeve in a vertically sliding mode, the axial lead of the rotating shaft is parallel to the horizontal plane, a spring for providing vertical elastic force for the tensioning slide block is further arranged between the sliding guide sleeve and the tensioning slide block, the pressure between the tensioning wheel and a steel wire rope can be adjusted according to the tightness of a speed limiter steel wire rope through the compression of the spring, and the space is saved.
Description
Technical field
The utility model relates to a kind of velocity limiter swelling device that is used for elevator.
Background technology
In the prior art, the velocity limiter swelling device of elevator generally includes and is arranged on tensioner slide block that can vertically slide up and down in the sliding guide sleeve and the expansion tightening wheel that is fixed on the tensioner slide block, on the tensioner slide block, hang with weight, when moving, elevator provides downward pressure for swelling device, make winding that enough big friction be arranged between steel rope on the expansion tightening wheel and expansion tightening wheel, the linear velocity that guarantees steel rope and expansion tightening wheel with the tensioner speed limiter wire rope is in full accord, but because the quality of weight is a unmodified, can not regulate the size of pressure between expansion tightening wheel and the steel rope according to the degree of tightness of steel rope, and occupation space is big.
Summary of the invention
The purpose of this utility model provides the velocity limiter swelling device of size of pressure between a kind of scalable expansion tightening wheel and the steel rope and space-saving elevator.
To achieve the above object, the technical solution of the utility model is: a kind of velocity limiter swelling device of elevator, it comprises the sliding guide sleeve that vertically extends, be arranged on the tensioner slide block in the sliding guide sleeve, the turning cylinder that one end is connected with described tensioner slide block, be set in the expansion tightening wheel on the described turning cylinder, described tensioner slide block vertically slides up and down to match with described sliding guide sleeve, the axis parallel of described turning cylinder also is provided with the spring that promising tensioner slide block provides the vertical direction elastic force in horizontal surface between described sliding guide sleeve and the described tensioner slide block.
Be provided with the pressing plate that can vertically move in the described sliding guide sleeve, the upper end of described pressing plate and described spring is inconsistent.
Have screw on the described sliding guide sleeve, passed bolt in the described screw, an end and the described pressing plate of described bolt are inconsistent.
The utility model has the advantages that: owing between the top of described sliding guide sleeve and the described tensioner slide block spring that promising tensioner slide block provides the vertical direction elastic force is set also, compared with the prior art can regulate the size of pressure between expansion tightening wheel and the steel rope according to the degree of tightness of speed limiter wire rope, and save the space.

The specific embodiment
The velocity limiter swelling device of elevator as shown in Figures 1 and 2, it comprises the sliding guide sleeve 6 that vertically extends, be arranged on the tensioner slide block 4 in the sliding guide sleeve 6, the turning cylinder 5 that one end is connected with described tensioner slide block 4, be set in the expansion tightening wheel 3 on the described turning cylinder 5, described tensioner slide block 4 vertically slides up and down to match with described sliding guide sleeve 6, the axis parallel of described turning cylinder 5 is in horizontal surface, between described sliding guide sleeve 6 and the described tensioner slide block 4 spring 2 that promising tensioner slide block 4 provides the vertical direction elastic force is set also, steel rope 8 windings (as shown in Figure 2) on expansion tightening wheel 3 during the elevator operation, when the pulling force that makes progress of 8 pairs of expansion tightening wheels 3 of steel rope of motion becomes ambassador's expansion tightening wheel 3 and upwards slides, pressure reduces thereupon between expansion tightening wheel 3 and the steel rope 8, by driving also upward movement of tensioner slide block 4 with expansion tightening wheel 3 bonded assembly turning cylinders 5, thereby holddown spring 2 produces downward antagonistic force moves downward expansion tightening wheel 3, reaches the purpose of regulating pressure between expansion tightening wheel 3 and the steel rope 8.The pulling force that 8 pairs of expansion tightening wheels 3 of steel rope of motion make progress is big more, and the antagonistic force that expansion tightening wheel 3 is moved downward that spring 2 produces is also big more, thereby can regulate the size of pressure between expansion tightening wheel 3 and the steel rope 8 according to the degree of tightness of steel rope 8, and has saved the space.
Be provided with the pressing plate 1 that can vertically move in the described sliding guide sleeve 6, the upper end inconsistent (described upper end refers to the end away from tensioner slide block 4) of described pressing plate 1 and described spring 2.
Have screw on the described sliding guide sleeve 6, passed bolt 7 in the described screw, an end and the described pressing plate 1 of described bolt 7 are inconsistent, can regulate the degree that compresses that regulating spring 2 is come in the position of pressing plates 1 by bolt 7.
