Abstract
Description
Technical Field
[0001] This invention belongs to the field of forklift modification technology, and in particular relates to a universal mounting structure and method suitable for the multi-functional development of the rear of counterbalance forklifts. Background Technology
[0002] Counterbalance forklifts are widely used in factory cargo transfer, warehouse loading and unloading, and other operations. Some scenarios require the addition of extended functional components such as towing trailers, auxiliary load-bearing devices, and rear supports to the rear of the forklift. Currently, the industry standard for forklift rear modification is to weld extension brackets on-site. Specifically, after removing or retaining the original counterweight, a custom extension mechanism is directly welded to the counterweight mounting bracket at the rear of the forklift.
[0003] This traditional modification method has many drawbacks: First, the modification process is irreversible. The welded structure is rigidly connected to the frame, and to restore it to its original factory condition, it can only be cut and ground, which can easily damage the original vehicle body panels, cause frame deformation, and reduce the structural strength of the forklift. Second, it has poor versatility. Each set of welded brackets is only suitable for a single function. Changing the operating function requires cutting and welding new brackets again, resulting in a long modification cycle. Third, the modification cost is high. Each modification requires on-site measurement, custom processing, and welding correction, resulting in high consumption of labor and materials. Fourth, there is no unified standard for welding quality. Long-term heavy-duty operation can easily lead to weld cracking and bracket loosening, posing a safety hazard. Summary of the Invention
[0004] To at least partially solve the technical problems existing in the prior art, the present invention provides a universal mounting structure and method suitable for the multi-functional development of the rear of counterbalance forklifts.
[0005] This invention relates to a universal mounting structure for the multi-functional development of the rear of counterbalance forklifts. It is installed on the original counterweight mounting frame of the forklift and includes a multi-functional modified transition mounting body, a pin, a multi-functional modified base, a pin baffle, transition mounting body bolts, and pin baffle bolts. The multi-functional modified transition mounting body is detachably fixed to the original counterweight mounting frame of the forklift via the transition mounting body bolts. One end of the pin is fixed to the front end of the multi-functional modified base, and the other end of the pin can slide through the multi-functional modified transition mounting body. The pin baffle is located on the outside of the multi-functional modified transition mounting body, and the pin baffle bolt passes through the pin baffle and is detachably locked to the end of the pin, achieving axial positioning of the pin.
[0006] Furthermore, in the above-mentioned universal mounting structure applicable to the multi-functional development of the rear of counterbalance forklifts, the multi-functional modified transition mounting body includes two symmetrically arranged mounting reinforcement blocks and a connecting plate. The connecting plate is welded and fixed between the two mounting reinforcement blocks, so that the two mounting reinforcement blocks form an integral load-bearing structure. A pin hole for sliding through the middle of the mounting reinforcement block is provided.
[0007] Furthermore, in the aforementioned universal mounting structure applicable to the multi-functional development of the rear of counterbalance forklifts, bolt fixing holes are provided at the upper and lower ends of the two mounting reinforcement blocks, and the bolts of the transition mounting body are correspondingly inserted into the bolt fixing holes, thereby realizing the detachable and fastened connection between the multi-functional modified transition mounting body and the counterweight mounting frame.
[0008] Furthermore, in the aforementioned universal mounting structure applicable to the multi-functional development of the rear of counterbalance forklifts, the pin shaft and the front end of the multi-functional modified base are welded together as a single structure, and the pin shaft and the pin shaft hole of the multi-functional modified transition mounting body are clearance-fitted, allowing the multi-functional modified base to swing slightly relative to the multi-functional modified transition mounting body.
[0009] Furthermore, in the aforementioned universal mounting structure applicable to the multi-functional development of the rear of counterbalance forklifts, the transition mounting bolts are symmetrically arranged high-strength anti-loosening bolts, which evenly distribute the operating load at the rear.
[0010] Furthermore, in the aforementioned universal mounting structure applicable to the multi-functional development of the rear of counterbalance forklifts, the multi-functional modified base is a multi-functional extended mounting base, which can be adapted to install any one of the functional modules of traction, mounting, and auxiliary support.
[0011] The present invention provides a universal mounting method for the multi-functional development of the rear of a counterbalance forklift, comprising the following steps: S1. Remove the original counterweight of the counterbalance forklift, clean the mounting reference surface of the original counterweight mounting bracket, and ensure that the mounting surface is flat and free of impurities. S2. Place the multi-functional modified transition mount on the lower support plate of the original vehicle counterweight mounting frame, and align the rear side of the multi-functional modified transition mount with the mounting plate of the counterweight mounting frame. S3. Secure the multi-functional modified transition mounting body to the counterweight mounting frame by using multiple sets of transition mounting body bolts. S4. Align and install the multi-functional modified base with the pin fixed at the front end, so that the pin is inserted into the pin hole of the multi-functional modified transition mounting body to complete the hinge fit. S5. Fit the pin baffle onto the outer end of the pin, and lock the pin baffle with the pin baffle bolts to complete the overall structure assembly. S6. When it is necessary to restore the original vehicle condition, disassemble the pin baffle bolts, pin baffle, pull out the pin, remove the transition mounting bolts, remove the multi-functional modified transition mounting body, and reinstall the original vehicle counterweight to complete the restoration.
[0012] The universal mounting structure and method of the present invention, applicable to the multi-functional development of the rear of counterbalance forklifts, has the following advantages and beneficial effects: This invention uses bolts and pins for mechanical assembly, eliminating the need for welding, drilling, cutting, or other destructive processing on the original vehicle counterweight mounting frame. When no modification is required, all modified parts can be completely removed, and the original factory counterweight can be reinstalled to fully restore the forklift to its factory condition, effectively protecting the structural strength of the original vehicle frame and avoiding the problem of damage to the vehicle body caused by traditional welding modifications. The multi-functional modified transition mounting body is compatible with the original counterweight mounting frame of conventional counterbalance forklifts. Its standardized and universal structure eliminates the need for separate customization. The multi-functional modified base can be quickly replaced with different functional modules such as towing, loading, and auxiliary support. One forklift can be adapted to various rear-end operation conditions, greatly improving equipment utilization. The assembly process is standardized, requiring no professional welding equipment or welders. A single person can complete all disassembly and assembly procedures, significantly reducing modification time and enabling rapid response to temporary expansion needs.
[0013] The transition mounting body is formed by welding double reinforcing blocks and connecting plates, resulting in good overall load-bearing capacity. The bolts of the transition mounting body are symmetrically arranged to evenly distribute the load, and the pin shaft is axially limited by a baffle to prevent the pin shaft from moving and falling off, thus avoiding the safety hazards of weld cracking, loosening and failure of traditional welded brackets.

[0017] like Figures 1 to 5 As shown, the universal mounting structure of the present invention, applicable to the multi-functional development of the rear of a counterbalance forklift, is installed on the original counterweight mounting bracket 100 of the forklift. It includes a multi-functional modified transition mounting body 1, a pin 2, a multi-functional modified base 3, a pin baffle 4, a transition mounting body bolt 5, and a pin baffle bolt 6. The multi-functional modified transition mounting body 1 is detachably fixed to the original counterweight mounting bracket 100 of the forklift via the transition mounting body bolt 5. One end of the pin 2 is fixed to the front end of the multi-functional modified base 3, and the other end of the pin 2 can slide through the multi-functional modified transition mounting body 1. The pin baffle 4 is located on the outside of the multi-functional modified transition mounting body 1. The pin baffle bolt 6 passes through the pin baffle 4 and is detachably locked to the end of the pin 2 to achieve axial limiting of the pin 2.
[0018] Furthermore, in the above-mentioned universal mounting structure applicable to the multi-functional development of the rear of counterbalance forklifts, the multi-functional modified transition mounting body 1 includes two symmetrically arranged mounting reinforcement blocks 11 and a connecting plate 12.

It can be adapted to different functional modules such as traction seats, mounting frames, and auxiliary supports according to different operational needs. The front end of the multi-functional modified base 3 is a flat docking structure, and the whole has a high strength load-bearing capacity, which can meet the heavy-load operation needs of the rear of the forklift.

S3. Secure the multi-functional modified transition mounting body 1 to the counterweight mounting frame 100 by multiple sets of transition mounting body bolts 5. S4. Align and install the multi-functional modified base 3 with the pin 2 fixed at the front end, so that the pin 2 passes into the pin hole 13 of the multi-functional modified transition mounting body 1 to complete the hinge fit. S5. Fit the pin baffle 4 onto the outer end of the pin 2, and lock the pin baffle 4 with the pin baffle bolt 6 to complete the overall structure assembly. S6. When it is necessary to restore the original vehicle condition, disassemble the pin baffle bolt 6, pin baffle 4, pull out the pin 2, remove the transition mounting bolt 5, remove the multi-functional modified transition mounting body 1, and reinstall the original vehicle counterweight to complete the restoration.
