Description

Weighbridge cover hoisting vehicle

Technical Field

The utility model relates to a lifting vehicle, in particular to a weighbridge cover lifting vehicle.

Background Art

The current method of threshing and re-drying is that workers sort tobacco leaves and put them into iron tobacco boxes, and then pull the tobacco boxes full of tobacco leaves to the compactor. There is a floor scale under the compactor. The tobacco boxes full of tobacco leaves need to be weighed first, and the tobacco leaves are compacted after the weight of the tobacco boxes meets the requirements by adding or removing tobacco leaves. During the operation, since there are a lot of fragments in the tobacco leaves, these fragments will fall into the floor scale, causing the scale frame to get stuck. This causes inaccurate weighing of the floor scale. Therefore, maintenance personnel are required to clean and maintain the floor scale regularly.

When cleaning and maintaining the scale, it is necessary to contact a forklift across departments first, and it takes a long time to connect with the personnel at all levels. When using a forklift to lift the scale cover, skilled maintenance personnel are required to bundle and install the lifting steel rope and adjust the force balance. After the scale is cleaned and maintained, due to the small distance between the scale cover and the surrounding area of the foundation pit, the forklift operator needs to repeatedly align the cover before the cover can be placed on the scale frame in the foundation pit. The lifting process requires the cooperation of a forklift, the lifting accuracy is poor, the operation is cumbersome, and the maintenance efficiency is low. In addition, there is cross-operation between people and vehicles during the process, which poses certain safety hazards.

DETAILED DESCRIPTION

The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be interpreted as limiting the present invention.

An embodiment of the utility model: as shown in Figure 1, a floor scale cover lifting vehicle includes a frame 1, and a universal walking wheel 6 is respectively arranged on the four corners of the bottom surface of the frame 1. A lifting structure is arranged in the middle of the frame 1, and a seat plate 7 is fixedly arranged at the bottom of the lifting structure, and a floor scale cover connecting bolt 5 is arranged on the seat plate 7.

The universal wheel 6 is used to facilitate the movement of the frame 1, the seat plate 7 is used to connect the weighbridge cover plate 10, and the lifting structure is used to lift or lower the weighbridge cover plate 10. The utility model only needs one person to operate, which saves time and effort, effectively improves the cleaning efficiency, and has a high safety factor.

In a specific embodiment, the frame 1 is welded from square steel, and the frame 1 is specifically welded from four square steels into a rectangular parallelepiped structure. A support beam 11 is welded in the middle of the frame 1, and the support beam 11 is parallel to the wide side of the frame 1. The length of the frame 1 should be greater than the width of the floor scale so that the frame 1 can span across the floor scale. It can be understood by those skilled in the art that in addition to being welded from square steel, the frame 1 can also be made of other materials, such as angle iron, aluminum alloy, etc., as long as it can bear the weight of the floor scale cover plate 10 without deformation.

A first through hole is formed in the middle of the support beam 11 in the vertical direction, and the lifting structure is installed on the first through hole. The support beam 11 can improve the overall structural strength of the frame 1 on the one hand, and is used to install the lifting structure on the other hand.

Furthermore, the lifting structure includes an adjusting nut 8 and a lifting screw 9. The lower end of the lifting screw 9 is welded and fixed to the center position of the top surface of the seat plate 7. The lifting screw 9 is plugged into and slidably connected to the first through hole. The adjusting nut 8 is threadedly connected to the lifting screw 9. The adjusting nut 8 is located above the support beam 11.

When the seat plate 7 is connected to the weighbridge cover plate 10, the weighbridge cover plate 10 can be raised and lowered by rotating the adjusting nut 8. The adjusting nut 8 can be rotated using a wrench, an electric tool, or a pneumatic tool. It should be noted that this embodiment only provides a preferred solution for a lifting structure, and the lifting structure can also be replaced by other devices that can achieve push-pull, such as a cylinder, a hydraulic cylinder, or an electric push-pull rod.

Furthermore, a guide support 2 is welded and fixed to one side of the support beam 11. The guide support 2 is horizontally arranged and parallel to the long side of the frame 1. A guide hole is opened at the end of the guide support 2. A guide rod 3 is slidably installed in the guide hole. The lower end of the guide rod 3 is welded and fixed to the top surface of the seat plate 7.

By providing the guide support 2 and the guide rod 3, the seat plate 7 can be prevented from rotating, and the seat plate 7 and the weighbridge cover plate 10 can be quickly aligned and connected to improve work efficiency.

Furthermore, a second through hole is respectively opened on the four corners of the base plate 7, and four threaded holes are opened on the floor scale cover plate 10. The four second through holes are opposite to the four threaded holes, and the floor scale cover plate connecting bolts 5 are installed on the four second through holes. The floor scale cover plate connecting bolts 5 are threadedly connected to the floor scale cover plate 10 through the threaded holes.

Preferably, a mounting seat 12 is welded in the middle of one of the long sides of the frame 1, a pull rod 4 is rotatably mounted on the mounting seat 12, and a handle 13 is mounted on the end of the pull rod 4. The setting of the pull rod 4 and the handle 13 facilitates the staff to move the frame 1.

The method of using the utility model is as follows: when in use, the frame 1 is moved to the middle of the weighbridge cover plate 10, and the adjusting nut 8 is turned to drive the lifting screw 9 and the seat plate 7 to move downward until they contact the weighbridge cover plate 10, and then the position of the frame 1 is adjusted to align the four second through holes on the seat plate 7 with the four threaded holes on the weighbridge cover plate 10, and then the weighbridge cover plate connecting bolts 5 are used to connect and tighten. By turning the adjusting nut 8, the lifting screw 9, the seat plate 7 and the weighbridge cover plate 10 are driven to move upward and away from the weighbridge to a certain height. In this process, the guide rod 3 on the seat plate 7 cooperates with the guide support 2 to achieve the purpose of limiting the rotation of the weighbridge cover plate 10. The frame 1 and the weighbridge cover plate 10 are moved together to the outside of the weighbridge by the handle 13 and the pull rod 4, and the weighbridge cover plate 10 is removed. After the maintenance is completed, the weighbridge cover plate 10 can be put in place in reverse order according to the above steps.

The above describes in detail the structure, features and effects of the utility model based on the embodiments shown in the drawings. The above is only a preferred embodiment of the utility model, but the utility model is not limited to the scope of implementation shown in the drawings. Any changes made in accordance with the concept of the utility model, or modified into equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the description and the drawings, should be within the protection scope of the utility model.
