push mobile device

Abstract

The invention provides a floor push moving device, which comprises a guide rail (30), a driving trolley (10) and a driven trolley (20), wherein the driving trolley (10) is arranged on the guide rail (30); the driven trolley (20) is arranged on the guide rail (30) and is positioned behind the driving trolley (10); and at least one pair of driven trolley middle wheels is arranged between the driving trolley (10) and the driven trolley (20) and is close to driven trolley front wheels (21) or driven trolley rear wheels (22). According to the floor push moving device, the phenomenon of deviation between a roller and the guide rail caused by eccentricity due to instable center of gravity of the driven trolley can be avoided, so that the driven trolley and the guide rail are kept in linear contact with each other, the driven trolley is prevented from being derailed, and the stability and the safety of the floor push moving device are greatly improved.

Description

technical field [0001] The invention relates to assembly equipment for industrial assembly lines, in particular to a ground pushing mobile device. Background technique [0002] Such as figure 1 with figure 2 As shown, two trolleys (i.e., an active trolley 10' and a driven trolley 20') are generally used on the ground push line 30' to support the object 40' to be transported, so as to realize the automatic movement of the object 40' to be transported and improve Productivity. The existing active trolley 10' and the driven trolley 20' all adopt a single-sided two-wheel structure, and the roller 11' is supported by two deep groove ball bearings. [0003] see in conjunction image 3 Shown, existing push dolly is used for non-special-shaped (object to be transported 40 ' center of gravity all can be placed on active dolly 10 ', the central position of driven dolly 20 ') lighter object is applicable. But for the boom structure of the pump truck, on the one hand, the boom str...

Problems solved by technology

But for the boom structure of the pump truck, on the one hand, the boom structure of the pump truck belongs to a large and irregular shape (the front and rear centers of gravity of the object 40' to be transported cannot be placed at the center of the active trolley 10' and the driven trolley 20' at the same time. ) class, on the other hand, the boom assembly is also a unilateral special-shaped combination, that is to say, no matter how you adjust it, it is impossible to fix the center of gravity G1' and G2' of the front and rear installation of the boom assembly on the active trolley 10' and the driven trolley 20' center position

[0004] Therefore, for large and special-shaped parts such as the boom assembly, due to the uneven distribution of its own gravity, its center of gravity on the driven trolley cannot be at the center of the driven trolley, and the force on the driven trolley is unbalanced.

During the transportation process, since the center of gravity of the large and special-shaped parts is not at the center of the driven trolley, the driven trolley is easy to travel eccentrically, which causes serious wear between the roller and the guide rail, and eventually leads to failure of the roller bearing, which cannot normally support the roller. In addition, the eccentric The front wheel of the driven trolley is in point contact with the guide rail, and the reaction area of ​​the guide rail to the roller is small, which leads to the failure of the roller and the derailment of the driven trolley, damage to the objects to be transported and the trolley, and even serious casualties to the operators. security incident
