Description of the embodiments

The following detailed description of the embodiments of the present utility model is provided with reference to the accompanying drawings, so that the technical scheme of the present utility model is easier to understand and grasp, and the protection scope of the present utility model is defined more clearly.

The designer aims at a plurality of defects in the existing workpiece transferring and transporting process, when products are diverted and transported across areas, the products are required to be diverted after being lifted by means of a crane or a forklift, and the risks of damage to the products and injury to personnel are high. Therefore, the carrying device for heavy-load trans-regional connection is innovatively designed, is widely suitable for transferring in a factory workshop of a high-capacity gas cylinder, and solves the problems of product direction adjustment and trans-regional carrying in a region.

As shown in fig. 1 to 3, the carrying device for heavy-load cross-region connection is formed by assembling a V-roller conveying line 1, a 90-degree end point rotating mechanism 2, a positioning mechanism 4 and a travelling mechanism 3, wherein the travelling mechanism 3 is provided with a linear ground rail 31, a frame 32, a travelling motor 33 and a plurality of groups of travelling wheels 34 and is integrally connected with a part of the positioning mechanism. The linear ground rail 31 is arranged across regions, and is actually a straight rail passing through each region (A, B … … in fig. 1); the carriage 32 is driven by a travel motor 33 to slide along the linear rail 31 and is controlled to stop and locked by a positioning mechanism. The end point 90 DEG rotating mechanism 2 is provided with a fixed rotating shaft 21 and a rotating motor 22 which are integrated at one end of a frame 32, a quarter-arc rotating guide rail 23 which is distributed in each area, and a carrier 24 which is bridged on the fixed rotating shaft, the rotating guide rail and the frame at two ends. The carriage 24 is driven by the rotating motor 22 to rotate along the fixed rotating shaft 21, and is stopped at a first position W1 which is collinear with the parallel rail of the frame 32 and a second position W2 which is perpendicular to the frame; in particular, the carrier 24 still provides support at the second position W2 by providing a rail or bracket that maintains it in a horizontal position. The V-roller conveyor line 1 is formed by connecting a conveyor motor 11, a chain 12 and a plurality of sets of transmission rollers 13 based on a carrier 24, and the workpieces borne on the transmission rollers 13 are carried in a linear movement manner under the drive of the conveyor motor.

As is evident from the device infrastructure outlined above, as several major components of the device, V-roller conveyor lines are carried on travelling mechanisms, mainly for carrying the work pieces and for providing power for the linear movement carrying of the work pieces by means of distributed drive rollers. On the other hand, the walking mechanism is matched with the positioning mechanism, so that the function of carrying the workpiece across the region is realized. These two-part components and the functions they perform are relatively common and are not the focus of the claimed utility model. Besides, the end point 90-degree rotating mechanism is integrated by virtue of a frame, and the rotating guide rail of the end point 90-degree rotating mechanism is matched with the rotating guide rail of the end point 90-degree rotating mechanism to effectively connect the main components of the two parts of the starting mechanism and the V-shaped roller conveying line, which are related to workpiece steering and carrying, and endow the workpiece with the capability of adjusting the direction under the state of static load, so that the production management purposes of feeding and transregional transfer of a logistics line can be met.

From a further refinement, in the V-roller conveyor line, any one set of the driving rollers 13 is composed of a sprocket 131, a pair of conical wheels 132, and a conveyor shaft 133 integrally penetrating therethrough. The conveying rotating shaft 133 is fixedly assembled on the shaft seat, the slope surfaces of the conical wheels 132 are opposite, and the surfaces of the workpieces are tangent to the slope surfaces. All the chain wheels 131 are connected with the conveying motor 11 through the chain 12, and driven to synchronously rotate and stop. As shown in fig. 2, the paired conical wheels are adapted to bear gas cylinder workpieces with diameters below 7 tons and corresponding pipe diameters, and the point of contact of the workpieces with larger pipe diameters is slightly higher, and the point of contact of the workpieces with smaller pipe diameters is slightly lower. On the other hand, the length of the carrier 24 is sufficient to accommodate workpieces up to 12.5 meters.

The positioning mechanism 4 is provided with a matched electric cylinder 41 and a positioning hole 42; the linear ground rail is provided with positioning holes on the ground of each area, which correspond to the electric cylinders attached to the frame, so that the driving mechanism can be locked after reaching the designated positions of each area, and displacement is prevented in the process of turning the workpiece. Furthermore, positioning holes are distributed in the external object flow line and the receiving positions of all areas and correspond to the electric cylinders attached to the carrier, so that the carrier is locked, and the workpiece is transplanted linearly better.

The walking motor, the rotating motor and the conveying motor can be connected into the PLC controller through buses and are controlled to be started and stopped, limit switches and rigid stop components which are connected into the PLC controller through signals are distributed along the linear ground rail and the periphery of the fixed rotating shaft so as to ensure the accuracy of workpiece steering and operation in place,

in the operation process of the carrying device, when a product is input from the outside through a material flow line, the travelling mechanism moves and is positioned at the appointed position of the area A, the V-shaped roller conveying line is driven to rotate to a second position to be in track connection with the material, and after the workpiece is in place, the workpiece is rotated and reset to the first position to be in track connection with the frame; realizing workpiece feeding and 90-degree arrangement direction change. When the vehicle needs to be carried across the region, the electric cylinder attached to the vehicle frame is driven to be pulled out of the positioning hole, then the vehicle frame moves along the linear rail through the travelling wheel under the driving of the travelling motor, and after the vehicle frame reaches the designated position of the next region B, the electric cylinder is controlled to be reinserted into the positioning hole. And then the carrier is controlled to rotate as required, so that the workpiece can be guided into the area through the V-shaped roller conveying line.

In summary, the solution introduction and the embodiment detailed description of the utility model for the device designed for transporting heavy and long products in a limited space area can be seen, and the solution has substantial characteristics and improvements: the method realizes the problems of product direction adjustment and trans-regional transportation in the region, has better carrying engagement, and simultaneously suppresses the problems of product lifting risks and site limitation.

In addition to the above embodiments, other embodiments of the present utility model are possible, and all technical solutions formed by equivalent substitution or equivalent transformation are within the scope of the present utility model as claimed.
