Description

Technical Field

[0001] The invention relates to accessories for power forklifts, and in particular to a scale body structure of a weighing and metering forklift scale dedicated to power forklifts, which is applied to occasions such as logistics, warehousing, and factories where precise weighing and metering are required for transportation and stacking. Background Art

[0002] As we all know, accurate weighing and measurement are often required in logistics, warehousing, factories and other places where there is handling and stacking. The current measurement method is to use a forklift to transport the goods to the scale for weighing and measurement, and then use a forklift to transport the goods to the storage shelves or designated areas or to load them into the logistics vehicle. Summary of the invention

[0003] The purpose of the present invention is to design a weighing and metering forklift scale body structure specially used for power forklifts. The scale is installed on the forks of the power forklift and directly weighs and measures the goods without using a forklift to transport the goods to the scale for weighing and measuring. The structure is simple, the operation is convenient, the operation is stable, the weighing is fast and convenient, and the metering is accurate. It can meet the requirements of double fork handling and stacking metering under normal circumstances, and also meet the accuracy of single fork working independently.

[0004] The technical solution of the present invention is: the scale body structure of the weighing and metering forklift scale comprises a rear mounting plate, a front mounting plate, a joint bearing, a tension sensor, a bearing screw, a bearing fixing block, a side fixed strain beam, a lower fixing block of a fork frame and an upper fixing block of a fork frame, four side fixed strain beams are symmetrically installed at the upper and lower parts of the two side edges of the spaced and mutually parallel rear mounting plates and the front mounting plates respectively through beam fixing screws, the bearing fixing block is installed on the front mounting plate through screws, the bearing fixing block is located between the rear mounting plate and the front mounting plate and embedded in the side fixed strain beam, fixing screws are installed through the upper parts of the rear mounting plate and the front mounting plate, joint bearings are installed on the fixing screws between the rear mounting plate and the front mounting plate, the tension sensor is suspended on the joint bearing, the bottom of the tension sensor is connected to the bearing screw through a nut, the bearing screw is installed on the bearing fixing block, the upper fixing block of the fork frame and the lower fixing block of the fork frame are installed through locking screws at the upper and lower parts of the rear mounting plate, and the whole constitutes the scale body structure of the weighing and metering forklift scale specially used for power forklifts.

[0005] Furthermore, a scale body positioning lock is installed on the top of the upper fixing block of the fork frame.

[0006] Furthermore, two fork lateral fixing blocks are installed on the front mounting plate at intervals beside the side fixed strain beam by means of mounting screws.

[0007] Furthermore, a fork locking nut and a fork locking screw are installed on the front mounting plate.

[0008] The present invention has the following advantages:

[0009] 1. Install fixing screws through the upper part of the rear mounting plate and the front mounting plate, install spherical bearings on the fixing screws between the rear mounting plate and the front mounting plate, and install the tension sensor on the spherical bearing in a suspended manner. Since most of the rear part of the fixing screw is still in the hole opened in the front mounting plate and there is a certain gap between the hole of the mounting plate and the rear part of the screw, when the load of the forklift exceeds the design load during use, the rear part of the fixing screw contacts the inner wall of the hole of the front mounting plate to play an overload protection function.

[0010] 2. The scale body of this application adopts a split structure and is installed between each fork and the fork frame. It can be installed without other auxiliary equipment and is easy to install.

[0011] 3. Each scale body adopts independent tension sensor for measurement, which can not only meet the measurement of double forks carrying and stacking at the same time under normal circumstances, but also meet the accuracy of single fork working independently under special circumstances.

[0012] 4. The single tension sensor is used in combination with four side-fixed strain beams. During operation, the single tension sensor only reads the downward tension, and the forces in other directions are eliminated by the joint bearings on the upper part of the tension sensor. The side-fixed strain beams not only serve to fix the front and rear mounting plates in the front, rear, left and right directions, but also participate in the strain when subjected to forces in the up and down directions, without affecting the normal measurement of the single tension sensor, thereby ensuring the accuracy of the measurement.

[0013] 5. Due to the different fork installation opening sizes used by different power forklift manufacturers, two fork lateral fixing blocks and fork locking screws on the upper part of the front mounting plate are designed on the front mounting plate. The two fork lateral fixing blocks are used to fix the fork in the left and right directions, and the fork locking screws are used to fix the fork in the front and back directions, ensuring the universality of the opening sizes of forks of different brands and ensuring the stability of the fork fixation, thereby ensuring the measurement accuracy.

[0014] 6. All parts of the scale body are precision-machined and assembled with screws. No electric welding process is used during the assembly process, thus ensuring the precision and consistency of the dimensions and eliminating other problems such as scale body structure deformation, dimensional inconsistency, etc. caused by electric welding.

[0015] 7. Two side fixed strain beams are installed on both sides of the front and rear mounting plates to solve the problem of inconsistent weight of the goods placed on the front and rear forks.

[0016] 8. The front mounting plate and the rear mounting plate are connected by four side fixed strain beams. When the front mounting plate is subjected to a certain weight, the four side fixed strain beams also produce a certain downward bending deformation and play a role in fixing the left and right front and back.

[0017] 9. When the fork is subjected to force, it is not subjected to a vertical downward force, but a forward pulling force from the upper part of the fork and a backward pressure from the root of the fork. Therefore, the connection between the four side fixed strain beams and the front and rear mounting plates adopts a concave-convex fit to eliminate the friction between the side fixed strain beams and the mounting surfaces of the front and rear mounting plates. The force-bearing method is unique. BRIEF DESCRIPTION OF THE DRAWINGS
