AI Technical Summary
Traditional forklift counterweight calibration equipment has poor applicability and is prone to wheel deformation. It cannot adapt to counterweights of different sizes, and the weight acting on the wheels causes difficulty in movement or imbalance.
A forklift counterweight weight verification device was designed. It adopts a bidirectional threaded rod to adjust the support distance, and is equipped with casters and a hydraulic cylinder support structure. By adjusting the support distance and the caster storage groove design of the support plate, it can accommodate counterweights of different sizes and prevent the weight from acting directly on the casters.
This improves the applicability of the equipment, prevents wheel deformation, and ensures normal equipment movement and calibration accuracy.

Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of weighing equipment, and specifically relates to a forklift counterweight weight verification device. Background Technology
[0002] Counterweights are often called balance blocks or weights in industrial product design. They are used in many products.
[0003] Currently, counterweights used on forklifts, in order to ensure the balance of the forklift's weight, require weight verification after leaving the factory. Traditionally, counterweight weight verification involves lifting the counterweight with a forklift and transporting it to a weighbridge for weighing. While this achieves the purpose of weighing verification, it is quite cumbersome. Another method is to use a manual forklift with built-in weighing verification. The two arms of the manual forklift are inserted into the two lifting slots at the bottom of the counterweight, and the arms are raised to verify the counterweight. Although this method is convenient, it still has some problems. For example, the distance between the two arms of a traditional manual forklift is fixed and cannot be adjusted, while the distance between the two lifting slots at the bottom varies for different sizes of counterweights, thus reducing its applicability. In addition, when a traditional manual forklift lifts the counterweight, the weight of the counterweight ultimately acts on the forklift's wheels. However, the weight of the counterweight is extremely heavy, and the weight acting on the wheel mounting brackets can easily cause deformation of the wheel mounting brackets, making it difficult for the manual forklift to move or causing imbalance. Utility Model Content
[0004] The purpose of this utility model is to provide a forklift counterweight weight verification device, which has the advantages of strong applicability and protection against pressure damage.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a forklift counterweight weight verification device, including a mounting base, a bracket symmetrically arranged on one side of the mounting base, a hydraulic cylinder embedded in the center of the bracket, a support plate fixedly connected to the output end of the hydraulic cylinder, a contact plate provided on the top of the support plate, weight sensors symmetrically assembled between the support plate and the contact plate, a bidirectional threaded rod rotatably connected inside the mounting base, a connecting block fixedly connected to the bracket symmetrically threaded on the surface of the bidirectional threaded rod, an annular protrusion symmetrically bolted to the bottom of the support plate, a universal wheel assembled at the bottom of the annular protrusion, a storage groove for cooperating with the universal wheel on the bracket, and a support protrusion symmetrically fixedly connected to the bottom of the bracket.
[0006] The above technical solution is as follows: This utility model incorporates a bidirectional threaded rod inside the mounting base, which, in conjunction with a connecting block, allows for adjustment of the distance between the two supports when the bidirectional threaded rod is rotated. This adjustment controls the position of the contact plate on the support, enabling the insertion and lifting of counterweight blocks at different distances, thus improving applicability. An annular protrusion with casters mounted on it is installed at the bottom of the support plate. When not in use, the casters pass through a storage groove and contact the bottom surface of the support. When weight verification is required, the support plate is lifted by a hydraulic cylinder, causing the casters to retract into the storage groove. The support protrusion then supports the support, preventing weight from acting on the casters and ensuring normal equipment operation.
[0007] The present invention is further configured such that a push handle is fitted on the top of the mounting base, and a protective sleeve is fixedly fitted onto the handle end of the push handle.
[0008] The above technical solution facilitates the movement of the device by staff.
[0009] The present invention is further configured such that a display screen is installed inside the push handle, and the display screen is used in conjunction with a weight sensor.
[0010] The above technical solution facilitates the display of weight sensor data by the device.
[0011] The present invention is further configured such that sliding blocks are fitted at the top and bottom of the connecting block, and a sliding groove is provided inside the mounting base to slide and connect with the sliding blocks.
[0012] The above technical solution facilitates the sliding and limiting of the connecting block.
[0013] The present invention is further configured such that a plurality of limiting slide rods are fixedly connected to the bottom of the contact plate, and the limiting slide rods are slidably connected to the support plate.
[0014] The above technical solution is adopted to limit the up and down movement of the contact plate.
[0015] The present invention is further configured such that a plurality of limiting guide rods are equidistantly mounted on the bottom of the support plate, and the limiting guide rods are slidably connected to the bracket.
[0016] The above technical solution is adopted to limit the vertical movement of the support plate.
[0017] The present invention is further configured such that one end of the bidirectional threaded rod extends through to the outside of the mounting base and is fixedly sleeved with a rotating disk.
[0018] The above technical solution facilitates the rotation of the bidirectional threaded rod by the staff.
[0019] In summary, this utility model has the following beneficial effects:
[0020] 1. This utility model has a bidirectional threaded rod designed inside the mounting base. When used with the connecting block, the distance between the two brackets can be adjusted when the bidirectional threaded rod is rotated, thereby adjusting the position of the contact plate on the bracket. This allows the counterweight block to be inserted and lifted into the lifting slot at different distances, improving applicability.
[0021] 2. This utility model features an annular protrusion at the bottom of the support plate, with casters mounted on the protrusion. When not in use, the casters pass through a storage groove and contact the bottom surface of the bracket. When weight verification is required, the support plate is lifted by a hydraulic cylinder, causing the casters to be stored inside the storage groove. This allows the support protrusion to support the bracket, preventing the weight from acting on the casters and ensuring the normal operation of the equipment. Attached Figure Description
