Background

A typical transport device in a photovoltaic solar module transport apparatus is a synchronous belt transport. The speed reducer drives the synchronous belt to drive the synchronous belt to run, and the synchronous belt transmits the battery assembly to a required station. The traditional synchronous belt transmission is mostly composed of two groups of same aluminum alloy sections, belt wheel support plates, synchronous belt wheel sets, synchronous belts and the like. The aluminum alloy section bar is arranged on the machine body to form a transmission plane. The belt wheel support plate is provided with a belt seat bearing, the belt seat bearing is connected with a synchronous pulley set, and the synchronous pulley set is arranged on the support plate. The driving synchronous belt pulley support plate and the driven synchronous belt pulley are respectively arranged on the support plate. The synchronous belt is sleeved on the driving synchronous belt wheel and the driven synchronous belt wheel.

The first conventional tensioning mode is as follows: and tensioning the synchronous belt by using a tensioning wheel. Need add a set of take-up pulley and press on the tight limit of hold-in range, press through the area tension of adjusting the take-up pulley, make the work that the hold-in range can be stable, this kind of tensioning mode need be equipped with a set of take-up pulley group alone. The synchronous belt tensioning device has the advantages of being complex in structure, time-consuming to install, high in cost and inconvenient to align and maintain, particularly, the tensioning wheel presses the synchronous belt with certain tension for a long time, abrasion of the synchronous belt is accelerated, and fatigue strength of the synchronous belt is improved.

The second conventional tensioning mode: the tensioning of the synchronous belt is realized by adjusting the distance of the driven synchronous pulley support plate. An aluminum alloy plate or a steel plate with the thickness of 8 mm-10 mm is used as a synchronous belt pulley support plate, and a belt seat bearing and a positioning block are arranged on the synchronous belt pulley support plate through a series of processing. The supporting plate and the tensioning supporting block are respectively arranged on the aluminum alloy section, the tensioning bolt is screwed into the screw hole of the positioning block, the positioning block is limited by the bolt head, the supporting plate can be displaced by screwing and adjusting the tensioning bolt, so that the driven synchronous belt wheel is displaced along with the supporting plate, the distance between the two groups of synchronous belt wheels is adjusted, and the synchronous belt meets the requirement on belt tension.

The synchronous pulley support plate with the structure has the advantages of large thickness, heavy weight, high raw material consumption, high processing procedures and high manufacturing cost. The installation is loaded down with trivial details, and adjustment, dismantlement, maintenance etc. are inconvenient, and installation stability is poor.
