And a pulley for mounting a steel wire rope is arranged on the counter-weight top beam.

The outer side of each counterweight longitudinal beam is provided with a guide piece matched with the counterweight guide rail.

The number of the guide pieces is at least 2.

Compared with the prior art, the utility model has the following advantages:

firstly, the bottom of the counterweight is provided with the buffer device, so that the buffer device does not need to be independently installed at the bottom of an elevator shaft, the construction time is reduced, the configured buffer can be assembled on a production field during counterweight production, the assembly quality is better guaranteed, and even if the buffer device is installed in the elevator shaft, the existing buffer device can still be used over against the buffer head.

The buffer device comprises a middle buffer and side buffers arranged on two sides of the middle buffer, and the side buffers can act on the buffer heads through the hinged sleeves only when the middle buffer contracts to a certain degree, so that the buffer device is prevented from touching the bottom.

Detailed Description

The utility model is described in detail below with reference to the figures and specific embodiments.

Example (b):

as shown in fig. 1 and 2, the present invention provides a counterweight structure having a buffering device, which includes a counterweight frame, counterweight blocks 3, and a buffering device installed at the bottom of the counterweight frame. The upper end of the counterweight frame is provided with a pulley 2 for installing a steel wire rope, the counterweight frame comprises two counterweight longitudinal beams 1 which are vertically placed, the two counterweight longitudinal beams 1 are used for fixing two ends of a plurality of counterweight blocks 3, and the outer side of each counterweight longitudinal beam 1 is provided with at least two guide pieces 4 for being matched with counterweight guide rails.

The bottom of two heavy longitudinal beams 1 is connected with heavy floorbar 5, buffer installs on heavy floorbar 5, buffer includes middle buffer 6 that is in the middle position of heavy floorbar 5 and two side buffers 7 that the symmetry set up in middle buffer 6 left and right sides (in this example, middle buffer 6 and side buffer 7 can adopt the cylinder, the hydro-cylinder, damping spring isotructure), the surface of middle buffer 6 is equipped with buffer nut 61, buffer nut 61 installs in the bottom to heavy floorbar 5, when middle buffer 6 receives the impact, buffer nut 61 acts on the lower surface to heavy floorbar 5, play main bearing effect, simultaneously in order to promote the impact resistance to heavy floorbar 5, be equipped with reinforcing ring 52 at the lower surface to heavy floorbar 5, be used for cooperating with buffer nut 61.

As shown in fig. 3, the upper end of the intermediate buffer 6 is inserted into the inside of the bottom counterweight block 3, and thus counterweight block through holes 31 are provided in the centers of the counterweight blocks 3 located at the lower part of the counterweight group.

The lower extreme of middle buffer 6 is equipped with protractile telescopic link 62, the surface cover of telescopic link 62 is equipped with hinge sleeve 8, hinge sleeve 8's both sides symmetry respectively are equipped with the hinge otic placode, two hinge otic placodes articulate respectively in the one end of side buffer 7, the other end of side buffer 7 is installed in the bottom both sides portion to heavy floorbar 5 through articulated seat 71, the equidistant two rows of mounting holes 51 that are equipped with in bottom to heavy floorbar 5, install in mounting hole 51 selectively through articulated seat 71, can realize hinge sleeve 8 and the adjustment to heavy floorbar 5 bottom distance, adopt clearance fit's relation between hinge sleeve 8 and the telescopic link 62, telescopic link 62 can freely slide in hinge sleeve 8.

The bottom of the telescopic rod 62 is provided with a buffer head 63, and when the telescopic rod 62 is contracted to a certain degree, the buffer head 63 upwards props against the lower surface of the hinge sleeve 8, so that the support of the side buffer 7 on the buffer head 63 is realized.

Under normal conditions, the telescopic rod 62 is in the state of stretching out, also has certain distance between articulated cover 8 and the buffering head 63, and only when telescopic rod 62 contracts to a certain extent, buffering head 63 just can move to the position of articulated cover 8, and side buffer 7 just can play a role.

In conclusion, the buffer device at the bottom of the shaft at the counterweight side is integrated in the counterweight, so that the use amount of the counterweight can be reduced, the installation time of the buffer device during field construction can be shortened, and the efficiency is improved.
