Abstract

The invention discloses a counterweight safety clamp device, which comprises a counterweight frame, a counterweight safety clamp and a lower beam, wherein the counterweight safety clamp is arranged on the lower side of the counterweight frame; the lower beam is connected with the counterweight frame through a supporting part; and a bottom guide shoe is arranged on the lower side of the lower beam. In the technical scheme, the lower beam is arranged on the counterweight safety clamp device and connected with the counterweight frame through the supporting part and the bottom guide shoe is arranged on the lower beam, so that the counterweight safety clamp device has high structural rigidity and is stable and reliable and the supporting part can bear major acting force when a counterweight is collided with a buffer. The counterweight safety clamp device can be applied to high-speed or large-tonnage elevators.

Description

The counterweight safety device
Technical field
The present invention relates to a kind of counterweight safety device that is used for elevator.
Background technology
Most of generally speaking elevator is counterweight safety not to be set, and the counterweight safety operated by rotary motion perhaps can be provided with counterweight safety in cab under the unsettled situation of pit.
Counterweight safety is the protection of implementing under the situation of the up appearance hypervelocity of protection Elevator weight sensor; if elevator cage is at top layer; general counterweight can be at pit; if under the situation that hypervelocity is rushed to summit, counterweight can be broken through buffering spacing (the GB regulation is 150-400mm) and buffering stroke (it is different that the different bufferings of energy disperser form specification).During the up hypervelocity of car, it is out of control that the speed monitoring original paper can detect the speed of up car, its lower limit is 115% of a rated speed of lift, the upper limit is that (governor tripping speed of counterweight safety should be higher than the governor tripping speed of car safety for the responsiveness of counterweight safety velocity limiter, but must not be higher than 10%), counterweight safety can clamp guide rail and make the car stop, or makes its speed be reduced to the scope of design of counterweight buffer at least.Counterweight safety is when making sky car stop, and its deceleration/decel must not be greater than 1gn.
Elevator guide shoe one has 4, and each two up and down, be stuck on the track, play the cab fixation.Leading has shoe guide (nylon material) in the boots, contact with three on guide rail, has oil box to lubricate guide rail outward.The bottom of general counterweight system is led boots and is directly installed under the counterweight safety arm length, poor rigidity, instability.
Summary of the invention
For overcoming above-mentioned shortcoming, the object of the present invention is to provide a kind of counterweight safety device that is used for elevator.
In order to reach above purpose, the technical solution used in the present invention is: a kind of counterweight safety device, comprise counterweight frame, be installed in the counterweight safety of counterweight frame downside, it also comprises the underbeam that is connected with counterweight frame by strut member, and the downside of underbeam is equipped with the bottom and leads boots.
Preferably, underbeam is a H-girder.
Further, counterweight safety is connected with speed limiter wire rope by a draw bar assembly.
A nearlyer step ground is equipped with the buffering base under the underbeam.
Preferably, the bottom is led boots and is led boots for rolling.
Owing to adopted technique scheme, counterweight safety device of the present invention increases underbeam, and underbeam is connected by strut member with counterweight frame, and the bottom is led boots and is installed on the underbeam, such structural rigidity is strong, reliable and stable, and strut member can bear main application force when the counterweight collision bumper.This counterweight safety device can be used at a high speed or the large-tonnage elevator.
Description of drawings
Accompanying drawing 1 is the front view of counterweight safety device of the present invention;
Accompanying drawing 2 is the left view of counterweight safety device of the present invention;
Accompanying drawing 3 is the section drawing of counterweight safety device of the present invention.
Number in the figure is:
1, counterweight frame; 2, strut member; 3, counterweight safety; 4, draw bar assembly; 5, underbeam; 6, boots are led in the bottom; 7, buffering base.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is described in detail, thereby protection scope of the present invention is made more explicit defining so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that.
With reference to accompanying drawing 1 to accompanying drawing 3, the counterweight safety device in the present embodiment, a kind of counterweight safety device, it comprises counterweight frame 1, counterweight safety 3 and underbeam 5.Counterweight frame 1 is connected by strut member 2 with underbeam 5.Counterweight safety 3 is installed in counterweight frame 1 time, and counterweight safety 3 is hinged with draw bar assembly 4, and is connected with speed limiter wire rope by draw bar assembly 4.When elevator normally moved, draw bar assembly 4 was positioned at the B1 position, and safety tongs is not worked; When operation exception appears in elevator, velocity limiter work by steel rope pulling draw bar assembly 4, makes draw bar assembly 4 be positioned at the B2 position, is clamped on the guide rail thereby drive counterweight safety 3, and elevator is shut down.
The bottom is led boots 6 and is installed in below the underbeam 5, elevator guide shoe divides to roll leads boots and sliding guide shoe, rolling is led boots and is stuck on the guide rail with 3 or 6 wheels, generally be used for speed at the elevator more than 2 meters, sliding guide shoe is that a chute is stuck on the track, generally be used for speed at the elevator below 2 meters, the bottom in the present embodiment is led boots 6 and is led boots for rolling.
Energy disperser breaks down or accident plays the effect of buffering when squatting the end at elevator, and oleo gear is owing to adapt to various speed tonnage demands and use commonplacely, and spring bumper is used for slower elevators.On underbeam 5 of the present invention the buffering base is installed, when the counterweight collision took place, the people of alleviating in elevator or the elevator avoided direct bump thereby buffering base 7 and energy disperser collide.
Theory and practice all proves, identical sectional area and the steel pipe of equal length and H-girder, the anti-bending strength of H-girder is good because sectional area when identical double-tee bending resistant section coefficient bigger than the bending resistant section coefficient of steel pipe.Consider that underbeam 5 will bear certain application force, so underbeam 5 preferred H-girders when the counterweight collision took place.Among the embodiment as shown in Figure 3, strut member 2 is selected steel pipe for use, both can reach the requirement of strength of support, again saving in material; Between heavy 1, all be locked by screw between strut member 2 and the underbeam 5, this connection mode is simple in structure, but not unique.Buffering base 7 is installed in the bottom surface of H-girder, and the position of corresponding each buffering base 7 is equipped with two strut members 2 in the H-girder bottom surface, and like this, strut member 2 can bear main application force when the counterweight collision bumper.
Above embodiment only is explanation technical conceive of the present invention and characteristics; its purpose is to allow the people that is familiar with this technology understand content of the present invention and is implemented; can not limit protection scope of the present invention with this; all equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
