Embodiment Construction

[0020] The technical scheme of the present invention will be further described below in conjunction with the accompanying drawings, but the required protection scope is not limited to the description;

[0021] As shown in Figure 1-2, the three-column gantry support climbing device provided by the present invention includes a mounting frame 8. The mounting frame 8 is an equilateral triangle and each end point is fixed with a lifting mechanism. Ten bytes 9 are connected, and a servo motor 10 is installed at one end of the ten bytes 9, and a drive shaft 7 is hinged on the other three end faces, and the other end of the drive shaft 7 is hinged with the input end of the lifting mechanism; The mechanism includes a reversing reducer 5, and the output end of the reversing reducer 5 is connected to two coaxially arranged sprockets 4.

[0022] Both sides of the upper end of the housing 51 of the reversing speed reducer 5 are hinged with a support link 2, the top of the support link 2 is...

Abstract

The invention discloses a three-upright-post portal support frame climbing device, which comprises an installing frame, wherein the installing frame is in a regular triangle shape, in addition, each end point of the installing frame is respectively and fixedly connected with a lifting mechanism, the middle part of the installing frame is fixedly connected with a cross joint, one end of the cross joint is provided with a servo motor, each of the other three end surfaces is respectively hinged to a transmission shaft, the other end of each transmission shaft is hinged to the input end of the lifting mechanism, the lifting mechanism comprises a reversing speed reducer, and the output end of the reversing speed reducer is connected with two chain wheels in coaxial arrangement. The three-upright-post portal support frame climbing device is matched with three groups of chains arranged on a portal frame to be used, the impact generated by sudden starting and sudden stopping of an ordinary ascending and descending machine can be effectively absorbed, the three-upright-post portal support frame climbing device is particularly applicable to the ascending and descending transfer operation of precision equipment or instruments, and the equipment or instruments cannot be damaged.

Description

technical field [0001] The invention relates to a lifting device, in particular to a climbing mechanism in the lifting device, in particular to a climbing device for a three-column gantry support. Background technique [0002] The lifting device is a common device for lifting or lowering objects. It can be realized by placing or fixing the object to be lifted on the fixed plate in the lifting device, and then driving the fixed plate to climb through the climbing mechanism in the lifting device. Object lifting, lifting devices are used in many fields, such as in the field of car maintenance, it is often necessary to use a lifting device to jack up the car and then check the chassis of the car; another example is a forklift, the front fork of which is mainly a lifting device, It is used to lift heavy objects for transportation or placement; there is also a wire rope-driven elevator, which mainly uses a wire rope to transfer the delivery platform connected to its end to achieve...
