TECHNICAL FIELD
[0001] The utility model belongs to elevator technical field, concretely relates to a counterweight frame convenient to installation. BACKGROUND
[0002] The counterweight is a component of the elevator traction system, which functions to reduce the power of the traction motor and the torque on the traction wheel and worm gear. However, the counterweight block is installed in the counterweight frame, and the counterweight frame is composed of an upper beam, a lower beam and side beams. The beams used in the existing counterweight frame are heavy structural steels such as I-beams, H-beams, channel steels, angle steels and square tubes. In order to ensure the strength of the counterweight frame, the thickness of the structural steels is usually large, which makes transportation and installation inconvenient and increases the cost. The beams in the counterweight frame are fixed by welding and form an integral structure, which cannot be replaced locally. During annual inspection and maintenance, if local defects are found, the entire counterweight frame needs to be replaced, which is high in cost, long in cycle, inflexible and inconvenient. SUMMARY

[0005] The end of the mounting frame facing the moving frame is provided with a slope.
[0006] A plurality of counterweight blocks are arranged side by side in the moving frame.
[0007] A plurality of bearing frames corresponding to the plurality of counterweight blocks are installed in the moving frame, the plurality of bearing frames are arranged side by side, and the counterweight blocks are located on the bearing frames.
[0008] A sliding wheel is installed at the bottom of the bearing frame, the sliding wheel is arranged to roll in the moving frame, one side of the moving frame provided with the connecting frame is provided with a limiting plate, and the bearing frame is fixedly connected with the limiting plate through bolts.
[0009] The mounting frame is provided with a limiting groove matched with the roller.
[0010] Compared with the prior art, the utility model has the following beneficial effects:
[0011] The utility model relates to a counterweight frame convenient to install, when installing counterweight blocks, the counterweight block is placed on the movable frame, then the movable frame is pushed to the elevator mouth, the elevator car is moved to the appropriate position and leaks the mounting frame, then the movable frame is pushed to the mounting frame, so that the movable frame is placed in the mounting frame, and locking and fixing are carried out through the bolt, the counterweight block is installed through the push -and -pull mode, and convenient replacement and installation are realized.
