[0002] Tracks are arranged inside the container, and a load is carried on a rail trolley to facilitate the loading, unloading and transfer of the load. Generally, the trolley is equipped with rollers or tires and needs to be braked after arriving at the position. It is quite common to rely on means such as brakes and brakes. However, for very valuable loads, relying on the current braking methods is not reliable enough. Therefore, it is very necessary to design a mechanism for reliable positioning after a trolley limiting mechanism. Summary of the Utility Model

[0003] The technical problem solved by the utility model is to limit the trolley with a load in the container, prevent the trolley from being unstably limited during transportation, and ensure the safety of load transportation.

[0004] To solve the above problems, the technical solution adopted by the utility model is:

[0005] A trolley limiting mechanism in a container is used to limit the trolley on the guide rail inside the container. It is characterized in that: there is at least one trolley in a single container. The trolley limiting mechanism includes a front limiting component and a rear limiting component, which are staggered from the trolley tires in the transverse direction, that is, the front limiting component and the rear limiting component are not in the tire traveling direction, and the guide rail has a groove, and the trolley tires roll in the groove; the front limiting component at least includes a front bracket component fixed on the container and a front limiting shaft fixedly connected to the chassis of the trolley. The front bracket component includes a front bracket, a first rotating shaft and a first rotating shaft support fixed at the bottom of the container. A first shaft hole matching the front limiting shaft and a second shaft hole matching the first rotating shaft are opened on the front bracket. When the front bracket rotates around the first rotating shaft to the vertical direction, the front limiting shaft is inserted into the first shaft hole, and the front bracket component prevents the trolley from moving forward. When the front bracket lies down, the whole front bracket is located below the chassis of the trolley and does not prevent the trolley from being pushed; the rear limiting component includes a rear support component, a pull rod component and a pull rod seat fixed on the chassis of the trolley. The rear support component includes a second rotating shaft support and a second rotating shaft fixed at the bottom of the container. When the pull rod component rotates around the second rotating shaft to the laid-down position, the whole of it is located below the chassis of the trolley and does not prevent the trolley from being pushed. When the trolley abuts against the front bracket component, the pull rod component is engaged with the pull rod seat, thereby restricting the trolley from retreating, and finally completing the limiting of the trolley. In addition, since the front part of the trolley is inserted into the first shaft hole, the rear part is in a tensioned state, and the wheels are trapped in the guide rail groove, the trolley can be prevented from tipping over.

[0006] Preferably, the front bracket is formed by welding a bottom plate, two side plates and a baffle, and its material is stainless steel; further, the front limit assembly further includes an anti-collision gasket, which is fixed on the front bracket assembly and made of rubber, playing a buffering role when the trolley leans against the front limit assembly.

[0007] Preferably, the pull rod assembly includes a pull rod, a fastening nut and a stop rod, and the stop rod is processed by milling and flattening one side of a round steel rod; further, the pull rod seat is formed by welding a connecting plate and two support plates, and a break hole is provided on the support plate; when the trolley is pushed in place, the pull rod assembly is lifted, the stop rod is hung into the break hole, and by tightening the fastening nut, the trolley is limited on the guide rail.

[0008] The beneficial effects brought by the present utility model are as follows: 1) The trolley limit mechanism includes a front limit assembly and a rear limit assembly, which limit the trolley in the front and rear directions; 2) By inserting the front part of the trolley into the first shaft hole, the rear part is in a tensioned state, and the wheels are trapped in the guide rail groove. Therefore, it can also prevent the trolley from tipping over; 3) When the front bracket and the pull rod assembly are turned over and laid down, it does not prevent the trolley from being freely pushed. After reaching the position, it can be turned over to the working position to limit the trolley. Description of the Drawings

When the trolley abuts against the front support assembly (10), the pull rod assembly (21) engages with the pull rod seat (22) to limit the backward movement of the trolley (3), and finally the limit of the trolley is completed.

[0022] Preferably, as Figure 5 and Figure 6 shown in the figure, the front support (10.1) is welded by a bottom plate (10.1.3), two side plates (10.1.2), and a baffle plate (10.1.1), and its material is stainless steel; further, as Figure 4 shown in the figure, the front limit assembly (4.1) further includes an anti-collision gasket (12), which is fixed on the front support assembly (10), and its material is rubber, which plays a buffering role when the trolley abuts against the front limit assembly (4.1).

[0023] Preferably, as Figure 8 and Figure 9 shown in the figure, the pull rod assembly (21) includes a pull rod (21.1), a fastening nut (21.2), and a stop rod (21.3), and the stop rod (21.3) is processed by milling one side of a round steel bar; further, as Figure 10 and Figure 11 shown in the figure, the pull rod seat (22) is welded by a connecting plate (22.2) and two support plates (22.1), and a break hole (300) is provided on the support plate; after the trolley (3) is pushed in place, the pull rod assembly (21) is lifted, the stop rod (21.3) is hung into the break hole (300), and the trolley is limited on the guide rail by tightening the fastening nut.

[0024] The beneficial effects brought by the present utility model are as follows: 1) The trolley limit mechanism includes a front limit assembly and a rear limit assembly, which limit the trolley in the front and rear directions; 2) By inserting the front part of the trolley into the first shaft hole, the rear part is in a tightened state, and the wheels are trapped in the guide rail groove. Therefore, it can also prevent the trolley from tipping over; 3) When the front support and the pull rod assembly are turned over and laid down, they do not hinder the free pushing of the trolley. After reaching the position, they can be turned over to the working position to limit the trolley.

[0025] The present utility model is not limited to the above embodiments. Any design method or design idea pointed out by the present utility model shall be considered within the protection scope of the present utility model.
