Trackless counter weight assembly and trackless lift car

Abstract

The invention discloses a trackless counter weight assembly and a trackless lift car. The trackless counter weight assembly comprises a counter weight housing assembly, wherein a guide rod used for guiding is respectively arranged at the two sides of the counter weight housing assembly, and a plurality of guide sleeve assemblies which are in a sliding fit with the guide rods are arranged on the side wall of an elevator. The trackless lift car comprises a lift car assembly, wherein the guide rod used for guiding is respectively arranged at the two sides of the lift car assembly, and a plurality of guide sleeve assemblies which are in a sliding fit with the guide rods are arranged on the side wall of the elevator. By adopting the trackless counter weight assembly and the trackless lift car in the technical scheme in the invention, a counter weight assembly and a lift car move up and down along a straight lie by utilizing the sliding fit between the guide rods and the guide sleeve assemblies, each guide rod is short, the processing process is simple, and linear error is small, thus bump and noise produced during the process that the counter weight assembly and the lift car are lifted as a track is long and joints are excessive can be avoided, the trackless counter weight assembly and the trackless lift car are convenient to transport and mount, components such as a special track, track support, special track pressure guide plate and the like can be saved, and the product cost can be reduced.

Description

technical field [0001] The invention relates to a vertical elevator, in particular to a counterweight device and a car of the vertical elevator. Background technique [0002] At present, in the elevator industry, in order to solve the problem of the elevator car running up and down and the counterweight, many manufacturers have installed counterweight guide shoes on both sides of the counterweight frame assembly and the car, and installed guide rails on the shaft wall of the elevator. The shoe runs up and down along the guide rail. This kind of counterweight device and car needs special rails, track bottom codes, track brackets, special rail pressure guide plates, rail pressure guide plate fastening bolts, counterweight guide shoes, counterweight connecting plates and connecting bolts, etc., and the parts are complex and numerous. , and in order to make the track slide better, it is necessary to install multiple lubricating oil cups, and add lubricating oil for the track to...

Problems solved by technology

In addition, due to the long track, it brings certain difficulties to transportation and installation. At the same time, the long track and many joints make it difficult to correct the distortion caused by the correction. The processing technology is complicated, the cost is high, the accuracy is difficult to guarantee, and the joints are also easy. Bumps and noises caused by bumps due to unevenness
