Background
The lift is as present material loading and unloading transport operation an indispensable instrument, to improving commodity circulation operating efficiency more and more important, and especially small-size hand lift is in improving single operating efficiency aspect, more and more being regarded as. Because the lift can lead to the lift platform to take place the slope because of the action of gravity of material in the use, hinder the flat smooth and easy rising of lift, increased the danger that takes place the incident when the operation simultaneously, so carry out the skew correction to lift platform, prevent that it from taking place the slope, it is very important to improve operating efficiency and operation security.
The anti-deflection modes of the lifting platforms with various structural forms are different, the traditional lifting platform of the lifter adopts a linear guide rail sliding block form as a sliding block form, and the lifting platform is fixed by the contact of the linear guide rail sliding block and a sliding rail to prevent the platform from deflecting; the lifting platform adopts a form that a hydraulic cylinder is matched with a chain wheel and a chain, and the lifting platform is matched with a lifting oil cylinder to prevent the platform from deflecting; the lifting platform adopts a form that a pulley is matched with a hand winch, and the lifting platform adopts the pulley to be arranged on the inner side of the slideway to be fixed so as to prevent the platform from deflecting. The various anti-deflection modes have the problems of unsmooth lifting of the platform, overlarge weight of the sliding block, inconvenience in installation and the like.
Aiming at the problems of the traditional elevator deflection prevention mode, the deflection prevention device has the advantages of simple structure, convenience in disassembly and assembly, light weight, small sliding blocking force and the like. At present, the use of elevators at home and abroad is developed towards civilization, miniaturization, lightweight and convenience, the reliable operation of an elevator lifting platform is ensured, and the inclination prevention and correction of the elevator lifting platform are very important.
Disclosure of Invention
The invention provides an anti-deflection device applied to a lifting platform of a small hand-operated lifter, which is used for realizing deflection correction of the lifting platform under unbalanced acting force when goods are loaded for operation and ensuring that the lifting platform slides smoothly according to a straight line to prevent the lifting platform from deflecting; it mainly comprises: an external guiding device [11] and a skew correction device [10 ].
The external guide device is composed of a guide wheel connecting fixing plate [1], an adjusting bolt [7] and a guide wheel [6 ]. The external guide part is fixed on the deflection correction part fixing frame through a connecting fixing plate by bolts and nuts, and the guide wheel is contacted with a main beam support of the elevator and is matched with the power of the lifting platform to roll on a sliding rail outside the main beam support.
The deflection correcting device consists of a correcting spring piece [8], a fixing bolt [9] and a spring fixing support [5 ]. The correction spring piece is an arched reed made of carbon steel with high elastic strength and fixed on the spring fixing support, the support is fixed on the lifting platform and slides along with the platform, when the lifting platform is inclined, the inclination correction is carried out by the rollers with front and rear staggered central axes installed in the staggered holes on the inner side and the external guide device, the correction spring piece plays a certain auxiliary correction role, and after the inclined load of the lifting platform is unloaded, the lifting platform can realize automatic correction under the device.
The invention can achieve the following obvious effects for preventing the long-falling platform from deflecting during operation:
