Technical Field

[0001] The utility model relates to the technical field of production line transfer equipment, and particularly relates to a trolley for transferring a transmission shaft. Background Art

[0002] For commercial vehicle enterprises with mixed-flow production of multiple varieties and small batches, due to the diversity of their own products, a variety of transmission shafts are required. Commercial vehicle transmission shafts are relatively heavy, and it is difficult to move multiple assembled transmission shafts manually. Using a forklift for transfer may cause logistics chaos and reduce the economy of short-distance in-line transportation.

[0003] In the prior art, a braking cable transfer trolley with the patent number CN210707551U includes a bottom bracket, longitudinal beams on both sides, and a top cross beam. The bottom ends of the longitudinal beams are fixedly connected to the sides of the bottom bracket. The number of longitudinal beams on each side is more than two and they are arranged in parallel. The cross beam is located directly above the center line of the bottom bracket and is parallel to the sides of the bottom bracket. The top ends of the longitudinal beams are fixedly connected to the cross beam, forming an angle between the longitudinal beams and the bottom bracket; wheels are provided at the four corners of the lower part of the bottom bracket; at least one "L"-shaped bent supporting rod is provided on each longitudinal beam. The short side of the supporting rod is fixed on the longitudinal beam and the long side is arranged towards the outside of the longitudinal beam. The supporting rods at the same height on one side together form a set of supporting components for placing the braking cable. The transfer trolley of the utility model has a greater load-bearing capacity, is convenient to use and has a higher transfer efficiency, which is beneficial to improving work efficiency and saving labor costs.

[0035] When manufacturing this trolley for transporting a transmission shaft, the four load-bearing units 2 are arranged at intervals along the vehicle length direction on the transfer trolley 1. There is an interval between adjacent load-bearing units 2. The middle interval has a first set distance, and the intervals on both sides have a second set distance. There is a length difference between the first set distance and the second set distance. The load-bearing unit 2 is used to support the transmission shaft. Since there is a length difference between the first set distance and the second set distance, two, three or four adjacent load-bearing units 2 can be selected to support the transmission shaft according to actual needs, which can better match the lengths of different types of transmission shafts, solving the problem in the prior art that the load-bearing structure composed of longitudinal beams and cross beams in the transfer trolley is equally spaced, making it difficult to meet the lengths of different types of transmission shafts. When the transmission shaft exceeds the distance between two load-bearing structures by too much, the load-bearing effect of the transfer trolley may be reduced due to force, resulting in problems affecting the transfer stability.

[0036] As Figure 1 shown, in some alternative embodiments, the transfer trolley 1 includes:

[0048] A supporting structure 23 is arranged on the support diagonal rod 22 and is used to cooperate with the support diagonal rod 22 to support the transmission shaft.

[0049] In this embodiment, the structure of the bearing unit 2 is specifically described. The bearing unit 2 includes a support cross rod 21, a supporting structure 23 and two support diagonal rods 22.

The supporting structure 23 is arranged on the support diagonal rod 22 and is used to cooperate with the support diagonal rod 22 to support the transmission shaft. The structure is simple and convenient to be installed on the transfer trolley 1.

[0050] As Figure 1 shown, in some alternative embodiments, the supporting structure 23 includes a plurality of supporting rods 231 arranged at intervals along the length direction of the support diagonal rod 22. The length direction of the supporting rod 231 faces upward and is used to form a supporting angle for clamping the transmission shaft with the support diagonal rod 22.

[0051] In this embodiment, the specific structure of the supporting structure 23 is described. The supporting structure 23 includes a plurality of supporting rods 231 arranged at intervals along the length direction of the support diagonal rod 22. The length direction of the supporting rod 231 faces upward and is used to form a supporting angle for clamping the transmission shaft with the support diagonal rod 22. The structure is simple, convenient to manufacture and install, and can transport multiple transmission shafts at the same time, improving the transfer efficiency.

[0052] As Figure 1 shown, in some alternative embodiments, the supporting structure 23 includes four supporting rods 231 arranged at intervals along the length direction of the support diagonal rod 22. The lowermost supporting rod 231 is connected to the transfer trolley 1.

[0053] In this embodiment, the specific number of the supporting rods 231 is described. The supporting structure 23 includes four supporting rods 231 arranged at intervals along the length direction of the support diagonal rod 22. The lowermost supporting rod 231 is connected to the transfer trolley 1, and multiple transmission shafts can be transported at the same time, improving the transfer efficiency.

[0054] As Figure 1 shown, in some alternative embodiments, the angle of the supporting angle formed by the supporting rod 231 and the support diagonal rod 22 for clamping the transmission shaft is 70°.

[0055] In this embodiment, the supporting rod 231 and the supporting diagonal rod 22 form a supporting angle for clamping the transmission shaft of 70°, which has good clamping stability and can accommodate transmission shafts of most diameters, improving the applicability of the trolley for transporting transmission shafts.

[0056] As Figure 1 shown, in some alternative embodiments, a connecting cross beam 3 is provided between adjacent bearing units 2, and both ends of the connecting cross beam 3 are respectively connected to the middle parts of the supporting cross bars 21 in the adjacent bearing units 2.

[0057] In this embodiment, a connecting cross beam 3 is provided between adjacent bearing units 2, and both ends of the connecting cross beam 3 are respectively connected to the middle parts of the supporting cross bars 21 in the adjacent bearing units 2, connecting all the bearing units 2, improving the stability of the bearing units 2, and further improving the safety during the transportation process.

[0060] As Figure 1 shown, in some alternative embodiments, the second set distance is greater than the first set distance.

[0061] In this embodiment, the second set distance is greater than the first set distance, making the distance between the two middle bearing units 2 smaller, setting the main load-bearing point of the trolley for transporting the transmission shaft at the center, and making the force more secure.

[0062] In summary, when manufacturing the trolley for transporting the transmission shaft, four bearing units 2 are arranged at intervals along the vehicle length direction on the transfer trolley 1, there are interval areas between adjacent bearing units 2, the middle interval area has a first set distance, the interval areas on both sides have a second set distance, there is a length difference between the first set distance and the second set distance, and the bearing unit 2 is used to support the transmission shaft. Due to the length difference between the first set distance and the second set distance, two, three or four adjacent bearing units 2 can be selected to support the transmission shaft according to actual needs, which can better match the lengths of different types of transmission shafts, solving the problem in the prior art that the bearing structure composed of longitudinal beams and cross beams in the transfer trolley is equidistantly arranged, making it difficult to meet the lengths of different types of transmission shafts. When the transmission shaft exceeds the distance between two bearing structures too much, the bearing effect of the transfer trolley may be reduced due to force reasons, and there is a problem affecting the transfer stability.
