Further, the both ends of the length direction of counterweight unit all are connected with the fixed plate, and the area of fixed plate is greater than the cross sectional area of tip, is provided with the fixed orifices on the fixed plate, and the fixed orifices passes through the screw connection on the side wall. The strength of the counterweight assembly is improved, the connection firmness is improved, and the structure of the support is stabilized.

Furthermore, a fixing hole is formed in the bottom surface of the counterweight component in a penetrating mode, and the fixing hole is fixedly connected with the ground of the pit through a penetrating fixing screw. The counterweight component is firmly fixed on the ground, plays a role in stabilizing, and has higher requirement on supporting strength due to the bottom of the connecting guide rail.

Furthermore, the inner side of the buffer fixing seat is fixedly welded with a fixing nut, a screw hole of the fixing nut corresponds to the connecting hole, and the fixing nut is connected with the edge of the buffer base in contact through welding.

Compared with the prior art, the utility model, have following advantage and effect: the device is a positioning and fixing structure used for installing the counterweight buffer and related components in an elevator pit, can save installation time, can calculate the required length after measuring the width of a well and the pit, can determine the pre-alignment positions of the guide rail and the buffer base, can position again without installation, improves installation efficiency, reduces installation and positioning time, improves elevator installation efficiency, and reduces labor intensity.
