Description
Technical Field
The utility model relates to the technical field of machine manufacturing, in particular to a winding mechanism for an overhead conveying lifting belt.
Background
The vehicle body welding conveying device is an important component of a welding production line. According to the relative position of the conveying line and the vehicle body part, the conveying line is divided into an overhead conveying line and a bottom conveying line. Overhead transfer chain adopts the overhead transport structure, and the hoist exists the risk that drops, has the strict demand to the overhead steel of factory building simultaneously, so the application is relatively less.
However, most parts of the air conveying structure are placed in the air, which is favorable for the process layout of a production workshop, so that the air conveying structure is indispensable for places with specific requirements on the field layout.
Besides basic functions such as conveying, the air conveying mechanism has safety performance which is a key of air conveying equipment. In the conveying mechanism, the lifting device is generally provided with a lifting belt, the lifting belt is made of polyurethane, steel wires are embedded into the polyurethane material of the lifting belt for enhancing the mechanical strength of the lifting belt, so that the lifting weight of the lifting belt can be increased by times, and the lifting device is the most typical safety measure of the manufacturing process of the lifting mechanism.
In the past elevating gear to the installation of lifting belt, can be at the one end drilling of belt, fasten on belt winding shaft with screw and clamp plate, and the drilling can make the embedded steel wire fracture of belt, has very big potential safety hazard, and only compress tightly with the clamp plate if not drilling installation, the belt can skid when promoting and drop, causes bigger incident.
Disclosure of Invention
The utility model aims to solve the defects in the prior art and provides a winding mechanism for an overhead conveying lifting belt.
In order to achieve the above purpose, the present utility model adopts the following technical scheme: a winding mechanism for conveying lifting belts in the air comprises a lifting belt (1), a belt winding shaft (2), a welding bracket (3), four belt guide wheels (4), a lifting driving mechanism (5), a coupler (6), a belt winding shaft large shaft (7) and a belt winding shaft small shaft (8);

FIG. 2 is an enlarged view of an internal cross section of the present utility model;
fig. 3 is a structural view of a belt winding shaft.
Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.
Referring to fig. 1-3, a winding mechanism for conveying lifting belts in the air comprises a lifting belt 1, a belt winding shaft 2, a welding bracket 3, a belt guide wheel 4, a lifting driving mechanism 5, a coupler 6, a belt winding shaft large shaft 7 and a belt winding shaft small shaft 8.
The middle section of the lifting belt 1 is lapped on a small belt winding shaft 8, is overlapped into a double layer, is wound around a large belt winding shaft 7 for one circle, and then two ends of the refreshing belt respectively go to the belt guide wheels 4 and drop into lifting points of a lifting appliance after reversing; the belt winding shaft 2 is connected with the lifting driving mechanism 5 through a coupler 6; the belt winding shaft, the belt guide wheel and the lifting driving mechanism are arranged on a 3-welding bracket through auxiliary parts (as shown in figure 1).
The middle section of the lifting belt is wound on the belt winding shaft, two ends of the lifting belt hang down through two belt guide wheels and serve as two lifting points for fixing fixtures, the lifting driving mechanism is connected with the belt winding shaft through a coupler, the driving torque enables the belt winding shaft to rotate, and therefore the lifting points connected with the two ends of the lifting belt lift up and down in the same part, and the lifting purpose is achieved. The lifting driving mechanism, the belt winding shaft and the belt guide wheel are arranged on the welding bracket through auxiliary parts.
Preferably, the structure of the belt winding shaft comprises a large shaft and a small shaft, one belt is lapped on the small shaft to form a double layer, the double layer belt is folded to form the double layer belt, the large shaft is wound at the same time, after one winding, two ends of the belt respectively go to two guide wheels, and the direction of the belt is changed through the two guide wheels to form two hanging points downwards at the same time (as shown in figure 2).
Preferably, if the lifting driving mechanism outputs in double shafts, two belt winding shafts can be driven, and the two belts synchronously lift up and down at four lifting points through four guide wheels, so that the lifting mechanism lifts up the crane piece more balanced, and the lifting weight can be larger (as shown in fig. 1).
Working principle: the lifting driving mechanism drives the belt winding shaft to rotate so as to pull the belt winding turntable, and at the moment, the belt end head rises at the synchronous lifting point; when the lifting driving mechanism commutates, the wound belt is slowly uncoiled from the winding shaft, and the hanging point of the end head of the belt descends synchronously; the winding and installation of the belt ensures that the integrity of the belt is not damaged by processing, and the strength is ensured. Meanwhile, a winding shaft winds a belt, two hanging points are released and tightened, the risk that the belt and the frame fall off is eliminated, and the lifting performance of a single belt is multiplied.
The foregoing is only a preferred embodiment of the present utility model, but the scope of the present utility model is not limited thereto, and any person skilled in the art, who is within the scope of the present utility model, should make equivalent substitutions or modifications according to the technical scheme of the present utility model and the inventive concept thereof, and should be covered by the scope of the present utility model.
