[0002] A trolley is a device used for storing, handling, and transporting goods or items. It usually consists of a frame, wheels, brackets, casters, etc. In industrial production, trolleys are usually used to transport objects with relatively large weights. Existing trolleys usually move on tracks driven by electricity. However, when the mass of the object is relatively large, the large weight will make it difficult for the trolley to move. When the trolley needs to be moved over a short distance, the large weight will cause the trolley to have a large inertia, making it difficult to move over a short distance. Moreover, the inertia of the trolley itself will also have a certain impact on the positioning of the trolley.
[0003] Therefore, the utility model provides a trolley push-pull conveying device. Summary of the Utility Model

[0022] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0023] Please refer to Figures 1 to 6 , the present utility model provides a technical solution: a trolley push-pull conveying device, including a trolley track 2, on which a trolley 1 and two mounting frames 3 are installed. A fixing structure is installed on the mounting frame 3, which corresponds to the trolley track 2. A first hydraulic cylinder 4 is fixed on one side of the mounting frame 3, and the output end of the first hydraulic cylinder 4 is fixed with a push-pull plate 8. A connecting structure is installed between the push-pull plate 8 and the trolley 1. A limiting structure is installed on one side of the mounting frame 3, and the limiting structure includes a fixed frame 14 and a limit plate 12. A support frame 15 is installed on one side of the fixed frame 14, and the limit plate 12 corresponds to the push-pull plate 8.
[0024] In this embodiment, the fixing structure includes a plurality of second hydraulic cylinders 5, the output end of the second hydraulic cylinder 5 is fixed with a pressure plate 6, the pressure plate 6 is in contact with the trolley track 2, and a groove 7 is opened in the mounting frame 3, and the groove 7 corresponds to the pressure plate 6.
[0025] Specifically, when the device needs to be installed, the mounting frame 3 is installed on the trolley track 2, and then the second hydraulic cylinder 5 is started, so that the output end of the second hydraulic cylinder 5 drives the pressure plate 6 to move until the pressure plate 6 is in contact with the trolley track 2, so that the two pressure plates 6 are clamped on both sides of the trolley track 2, and the mounting frame 3 can be fixed, and thus the trolley 1 can be pushed and pulled by the first hydraulic cylinder 4.
[0026] The connecting structure includes a first connecting plate 9 and a second connecting plate 10. The first connecting plate 9 is fixedly connected to the push-pull plate 8, the second connecting plate 10 is fixedly connected to the trolley 1, and a plurality of fixed pins 11 are installed between the first connecting plate 9 and the second connecting plate 10. A plurality of through grooves are opened in both the first connecting plate 9 and the second connecting plate 10, and the through grooves correspond to the fixed pins 11.
[0027] Specifically, when the push-pull plate 8 needs to be connected to the trolley 1, the first connecting plate 9 and the second connecting plate 10 are aligned up and down, and then the fixed pin 11 is inserted into the through groove, so that the first connecting plate 9 and the second connecting plate 10 can be connected together, and thus the trolley 1 can be driven to move by the first hydraulic cylinder 4.
[0028] A plurality of limit rods 13 are installed between the fixed frame 14 and the limit plate 12. The two ends of the limit rods 13 are fixedly connected to the fixed frame 14 and the limit plate 12 respectively. The length of the limit rods 13 is the sum of the length of the mounting frame 3 and the length of the first hydraulic cylinder 4 when it is contracted. The bottom of the support frame 15 is in contact with the ground, and a triangular structure is formed between the support frame 15 and the fixed frame 14.
[0029] Specifically, the fixing frame 14 is placed on one side of the mounting frame 3, and the supporting frame 15 can also be fixed to the ground by bolts. At this time, the limit plate 12 is located on the side of the first hydraulic cylinder 4 close to the trolley 1. When the trolley 1 moves under the action of inertia, the limit plate 12 contacts the push-pull plate 8, thereby limiting the push-pull plate 8 to prevent the push-pull plate 8 from squeezing the first hydraulic cylinder 4 under the action of the trolley 1, thereby limiting the trolley 1 and preventing the trolley 1 from moving.
[0030] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
