Technical Field

[0001] The utility model belongs to the technical field of conveyor lines, and in particular relates to a five-carriage group for a suspension conveyor line. Background Art

[0002] In industrial production, in order to realize the automatic transportation of materials, suspension conveyor lines are widely used. Suspension conveyor lines transport materials by hanging in the air, do not occupy ground space, can be flexibly arranged according to the production process, and are suitable for multi-storey factories and environments with limited space. The existing suspension conveyor line trolley group is limited by the length and load of a single vehicle. It is suitable for workpieces with a length of less than 1.5 meters and a load of less than 200KG, and cannot transport workpieces with a length of 2 meters and a weight of 300KG.

[0003] Therefore, the above problems need to be solved urgently. Utility Model Content

[0004] Purpose of the utility model: In order to overcome the above shortcomings, the utility model provides a five-trolley group for a suspended conveyor line, which meets the transportation needs of long workpieces, saves modification costs, increases the conveying load of the trolley group, and improves the adaptability of the conveyor line.

[0005] Technical solution: In order to achieve the above-mentioned purpose, the utility model provides a five-car group for a suspended conveyor line, including a front car group and a rear car group. A load-bearing beam is provided on the lower side of the front car group and the rear car group, and the front car group and the rear car group are respectively hinged at both ends of the load-bearing beam. The front car group includes a first front car and a second front car. A front crossbeam is provided on the lower side of the first front car and the second front car. The two ends of the front crossbeam are respectively hinged to the first front car and the second front car, and the front crossbeam is hinged to the load-bearing beam. The rear car group includes a first rear car, a second rear car, and a third rear car. A first rear crossbeam is provided on the lower side of the first rear car and the second rear car, and the two ends of the first rear crossbeam are respectively hinged to the first rear car and the second rear car. The second rear crossbeam is hinged to one end of the first rear crossbeam away from the first rear car, and the third rear car is arranged on the upper side of one end of the second rear crossbeam away from the first rear crossbeam, and the third rear car is hinged to the second rear crossbeam. During use of the utility model, a long workpiece is suspended on the lower side of the load-bearing beam, and a driving belt drives the front car group and the rear car group to move along the conveying track. The utility model lengthens the overall length of the trolley group, so that the lower side of the trolley group can be mounted with long workpieces without interference. And the added third rear car can increase the load of the trolley group and improve the mounting capacity. In the process of cornering transportation, since the front car group and the rear car group are respectively hinged with the load-bearing beam, the front car group first enters the curve to turn, and the rear car group is still in the straight section. The front car group and the drive belt are separated, and the drive belt drives the rear car group to move, and the rear car group pushes the front car group to move through the curve. When the front car group exits the curve and enters the straight section, the rear car group enters the curve. At this time, the drive belt drives the front car group to move, and the front car group drives the rear car group out of the curve. When the rear car group is in the curve, the hinged first rear beam and the second rear beam rotate as the curve proceeds, and the third rear car is prevented from derailing. The utility model has a simple structure and can meet the transportation needs of long workpieces without making major changes to the original suspension conveyor line, saving the transformation cost, and improving the transportation load of the trolley group and the adaptability of the suspension conveyor line.

[0006] Furthermore, in the above-mentioned five-car group for the suspended conveyor line, the first front car, the second front car, the first rear car, and the second rear car have the same structure, and the first front car includes a car body, and load-bearing wheels arranged on both sides of the car body, and the load-bearing wheels are arranged in pairs on both sides of the car body. A driving block is arranged on the upper side of the car body, and an accumulation wheel is arranged on the lower side of the car body, and the driving block and the accumulation wheel are connected by a connecting shaft. The connecting shaft is arranged through the car body, and the connecting shaft is located at the upper and lower ends of the car body and is provided with springs. During transportation, the driving block and the driving belt abut against each other, and friction occurs between the driving belt and the driving block, and the driving belt drives the driving block to move. When stopping, the accumulation wheel moves downward, and the driving block and the driving belt are disengaged.

[0007] Furthermore, in the above-mentioned five-cart group for the suspension conveyor line, the third rear car includes a rear car frame. The rear car frame is provided with rear load-bearing wheels in pairs on both sides. The rear car frame is provided with a stacking needle on the side away from the second rear car, and the stacking needle and the stacking wheel are arranged on the same vertical plane. The rear load-bearing wheel moves along the conveying track, and the third rear car provides a bearing capacity to increase the load conveyed by the car group. When the front and rear car groups come into contact, the stacking needle squeezes the stacking wheel to move downward, and the drive block and the drive belt are separated.

[0008] Furthermore, in the above-mentioned five-car group for the hanging conveyor line, the cross section of the accumulation needle is L-shaped, the vertical end of the accumulation needle is connected to the rear frame, and the vertex of the horizontal end of the accumulation needle is lower than the vertex of the accumulation wheel provided on the first front car. A guide portion is provided at the horizontal end of the accumulation needle. The guide portion is conical. The guide portion guides the accumulation needle to squeeze the accumulation wheel and move downward.

[0009] Furthermore, in the above-mentioned five-car group for the suspension conveyor line, a gap is provided between the first rear cross beam and the second rear cross beam. An end plate is provided at one end of the second rear cross beam close to the first rear cross beam. Connecting arms are provided at the upper and lower ends of the end plate, respectively. A connecting rod is provided at one end of the first rear cross beam close to the second rear cross beam, the connecting rod vertically passes through the first rear cross beam, and the upper and lower ends of the connecting rod respectively pass through the through holes provided in the connecting arm.

[0010] Furthermore, in the above-mentioned five-carriage group for the suspension conveyor line, in order to be able to suspend meter-long workpieces, the distance between the end of the front beam away from the second rear beam and the end of the second rear beam away from the front beam is greater than 2 meters.

[0011] It can be seen from the above technical scheme that the utility model has the following beneficial effects: the utility model uses a five-trolley group for the suspended conveyor line, which has a simple structure and can meet the conveying needs of long workpieces without making major changes to the original suspended conveyor line, thus saving the cost of transformation, and increasing the conveying load of the trolley group, thereby improving the adaptability of the conveyor line.

In order to hang a 2-meter-long workpiece, the end of the front beam 13 away from the second rear beam 25 is more than 2 meters away from the end of the second rear beam 25 away from the front beam 13.

[0019] During use of the utility model, the long workpiece is suspended on the lower side of the load-bearing beam 3, and the driving belt drives the front car group 1 and the rear car group 2 to move along the conveying track. The utility model adds a third rear car 23, lengthens the overall length of the trolley group, and enables the lower side of the trolley group to mount the long workpiece without interference. And the added third rear car 23 can increase the load of the trolley group and improve the mounting capacity. During the cornering transportation process, the front car group 1 first enters the curve to turn. Since the front car group 1 and the rear car group 2 are respectively hinged to the load-bearing beam 3, the rear car group 2 is still in the straight section, the front car group 1 is separated from the driving belt, the driving belt drives the rear car group 2 to move, and the rear car group 2 pushes the front car group 1 to move through the curve. When the front car group 1 exits the curve and enters the straight section, the rear car group 2 enters the curve. At this time, the driving belt drives the front car group 1 to move, and the front car group 1 drives the rear car group 2 out of the curve. When the rear vehicle group 2 is in a bend, the second rear cross beam 25 to which the third rear vehicle 23 is hinged is hinged to the first rear cross beam 24, and the first rear cross beam 24 and the second rear cross beam 25 rotate as the bend is made to avoid derailment.
