In the above counterweight support without welding, the first adapter plate is perpendicular to the base plate, the first adapter plate is perpendicular to the support arm, and the second adapter plate is perpendicular to the guide rail mounting plate.

In the above counterweight support without welding, an arc surface is provided at a joint of the base plate, the first adapter plate, and the support arm.

In the counterweight support without welding, an inclined plane is arranged on a side wall of the first adapter plate away from the support arm.

Compared with the prior art, the utility model can be processed and assembled in a workshop, and when the elevator is installed in an elevator installation site, the welding is not needed again, so that the installation of the counterweight support is simpler; the utility model discloses a split type structure has two pieces of bending, and two are bent and pass through bolted connection between the piece, make every be close to the intensity of heavy support, the steady quality. Furthermore, because the utility model discloses a bolted connection becomes whole, can not destroy metal surface coating, makes to be difficult to rust to heavy support, and life is longer. The utility model discloses a split type structure will the utility model discloses install behind the elevator shaft wall, be used for on the guide rail mounting panel and connect the hole site to heavy guide rail adjustable, guarantee the guide rail fixed orifices and align with the mounting hole to heavy guide rail. The support arm can guarantee that the counterweight support has higher bending strength, so that the counterweight guide rail is better supported. The cambered surface is used for eliminating stress and preventing the counterweight support from generating stress cracking at the cambered surface of the counterweight support. The utility model discloses a two pieces of bending are before bending (the exhibition flat state of the piece of bending promptly), one is the rectangle, and one is right trapezoid, and the shape is all more regular, is convenient for arrange the version unloading on the steel sheet, and the unloading waste material is few, and the effective utilization rate of steel sheet is high, can save material cost.

Therefore, the utility model has the advantages of the installation degree of difficulty is less, stable in quality and life are longer.
