Description

Technical Field

[0001] The utility model relates to the field of logistics sorting, in particular to a weighing trolley which is easy to maintain. Background Art

[0002] The automatic baggage sorting system for civil aviation logistics currently has various forms such as push plate sorting machine, cam sorting machine, tilt tray sorting machine, cross belt sorting machine, etc. The tilt tray sorting machine can not only handle the sorting of conventional baggage, but also be compatible with the sorting of some special-shaped items, and has stronger adaptability;

[0003] The tilting tray sorting machine is widely used in the logistics industry. For example, the packages are sorted according to their weight. Before sorting, the cart carrying the packages is weighed on the conveying system. When it reaches the specified position, the tipping mechanism turns the tilting tray over. However, the existing tilting tray weighing carts on the market have complex structures, and are very troublesome to install and maintain. Utility Model Content

[0004] The utility model aims to provide a weighing trolley which is easy to maintain, thereby solving the problem that the weighing trolley of a turnover machine in the prior art has a complicated structure and is very troublesome to install and maintain.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a weighing trolley that is easy to maintain, comprising a bottom plate, a fixing frame is fixedly connected to the upper end of the bottom plate, a supporting frame is fixedly connected to the upper end of the fixing frame, walking wheels are installed at the four outer ends of the bottom plate, and limiting wheels are installed at the upper two ends of the bottom plate, and the walking wheels and the limiting wheels can rotate independently;

[0006] Slide grooves are provided at both ends of the support frame, and a first fixing pin is movably connected inside the slide groove.

[0007] As a further description of the above technical solution: a weighing release is movably connected to the first fixing pin, and a second fixing pin is arranged through the top of the supporting frame.

[0008] As a further description of the above technical solution: a slot is provided inside the weighing release, and the second fixing pin is movably connected inside the slot.

[0009] As a further description of the above technical solution: both ends of the weighing release are rotatably connected with homing wheels.

[0010] As a further description of the above technical solution: the upper end of the weighing release is fixedly connected to a connecting plate, and the upper end of the connecting plate is fixedly connected to a plastic disk.

[0011] The utility model has the following beneficial effects:

[0012] 1. Compared with the prior art, this weighing trolley that is easy to maintain is provided with a weighing release at the connection between the upper and lower parts. The weighing release can realize the release function of the upper and lower parts of the trolley. In the actual weighing process, the return wheels on both sides of the trolley lift the upper part of the trolley as a whole. At this time, the fixing pin of the weighing platform is in a suspended state, and the overall weight of the upper part is pressed on the weighing platform, while the mechanism of the lower part and the upper part are no longer in contact, so that the weighing platform only obtains the weight of the mechanical mechanism of the upper part. After the weight of the upper mechanical structure itself is reset to zero, the weight of each package itself is obtained. Compared with the traditional trolley structure, the structure of this patent is simpler and more convenient to install and maintain.

[0013] Additional aspects and advantages of the present invention will be given in part in the following description, and in part will become apparent from the following description, or will be learned through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0020] Reference Figure 1-2The utility model provides an embodiment of a weighing trolley that is easy to maintain, including a bottom plate 8, a fixing frame 5 is fixedly connected to the upper end of the bottom plate 8, a support frame 6 is fixedly connected to the upper end of the fixing frame 5, and the entire device can be stably supported by the fixing frame 5 and the support frame 6. The four outer ends of the bottom plate 8 are all equipped with running wheels 9, and the upper two ends of the bottom plate 8 are equipped with limiting wheels 10, and the running wheels 9 and the limiting wheels 10 can rotate independently. The lower part of the vehicle is composed of a running chain bottom plate 8, a running wheel 9 and a limiting wheel 10. The chain is fixed on the bottom plate 8, driving the four running wheels 9 to move horizontally, and the two limiting wheels 10 play the role of limiting on the track;

[0021] Both ends of the support frame 6 are provided with a slide groove 4, and a first fixing pin 7 is movably connected inside the slide groove 4. By setting the slide groove 4, the first fixing pin 7 can be moved inside the slide groove 4. When the weighing release 2 is driven to rise, the first fixing pin 7 can move inside the slide groove 4, making it suspended;

[0022] The first fixed pin 7 is movably connected with a weighing release 2, and a second fixed pin 13 is provided on the top of the support frame 6. A slot 12 is provided inside the weighing release 2, and the second fixed pin 13 is movably connected inside the slot 12. The correspondence between the second fixed pin 13 and the slot 12 also enables the weighing release 2 to move on the second fixed pin 13 during movement. The two ends of the weighing release 2 are rotatably connected with return wheels 3, and the upper part of the trolley is lifted as a whole by the return wheels 3 on both sides of the trolley. At this time, the fixed pin of the weighing platform is in a suspended state, and the overall weight of the upper part is pressed on the weighing platform, while the lower part mechanism and the upper part are no longer in contact, so that the weighing platform only obtains the weight of the upper mechanical mechanism. After the weight of the upper mechanical structure itself is reset to zero, the weight of each package itself is obtained;

[0023] The upper end of the weighing release 2 is fixedly connected with a connecting plate 11, and the upper end of the connecting plate 11 is fixedly connected with a plastic plate 1, and the plastic plate 1 can support the package for weighing.

[0024] Working principle: When the device is in use, the trolley installation structure is designed to be divided into two parts, the lower part is composed of a running chain bottom plate 8, a travel wheel 9 and a limit wheel 10. The chain is fixed on the bottom plate 8, driving the four travel wheels 9 to move horizontally. The two limit wheels 10 play the role of limiting the position on the track. The upper part is assembled with the weighing release 2 structure, the plastic plate 1 and the lower hem track. When the trolley runs to the weighing section, the return wheels 3 on both sides of the trolley are used to lift the upper part of the trolley as a whole. At this time, the fixing pin of the weighing platform is in a suspended state, and the overall weight of the upper part is pressed on the weighing platform, while the lower part of the mechanism and the upper part are no longer in contact, so that the weighing platform only obtains the weight of the upper mechanical mechanism. After the weight of the upper mechanical structure itself is reset to zero, the weight of each package itself is obtained.

[0025] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
