Abstract
Description
Technical Field
[0001] This utility model relates to the field of forklift technology, and in particular to an installation mechanism for built-in wiring on a forklift and a hose pulley assembly. Background Technology
[0002] As the logistics industry continues to demand more from forklifts for multi-scenario and multi-functional applications, masts are no longer limited to being equipped with three or four valve hose pulley assemblies. For attachments with three or more actions, solenoid valves need to be configured on the attachments to achieve hydraulic circuit switching; for the requirement of forklift monitoring camera functionality, the forklift's own power supply is needed to ensure long-term endurance.
[0003] Both of these functions require guiding electrical wires from the vehicle body through the mast piping to the front of the fork carriage. While attachments and cameras are mounted on the fork carriage, the fork carriage is constantly moving. This causes the wires to easily become damaged or detached during frequent lifting and lowering of the forklift mast, resulting in a shorter lifespan. Furthermore, conventional wiring for attachments with solenoid valves is often externally mounted, severely obstructing the field of vision. Therefore, this invention proposes a forklift-mounted wiring installation mechanism with a rationally arranged electrical circuit and a three-stage fully free-flowing hose pulley system. Utility Model Content
[0004] The main objective of this utility model is to provide a forklift mounting mechanism for built-in wiring that offers good visibility, low cost, easy installation, and requires no modification to the original structural components, as well as a three-stage fully free hose pulley system.
[0005] To achieve the above objectives, this utility model proposes a mounting mechanism for built-in wiring on a forklift. The mounting mechanism is disposed on a mast assembly, which includes an outer mast, a middle mast, an inner mast, and a fork carriage. The fixing assembly includes a first pipe clamp support plate disposed on the outer gantry and an electric wire pulley bracket disposed on the middle gantry; The wiring system includes an electrical conduit fixed to the first pipe clamp support plate by a wire clamp, the electrical conduit being mounted on the first partition joint of the electrical pulley bracket and the fork carriage, one end of the electrical conduit being directly connected to the vehicle body power supply through a second rubber plug on the first partition joint, and the other end of the electrical conduit being connected to an attachment solenoid valve or a fork monitoring camera.
[0006] Furthermore, one end of the electrical conduit is inserted into the first rubber plug on the lower four-way bend assembly and is secured by a strap to the second pipe clamp support plate on the inner frame.
[0007] Furthermore, the electrical conduit is fixed to the third clamp support plate on the fork carriage by a dual-purpose pipe clamp.
[0008] Furthermore, the conduit is equipped with a wire locking plate, which is connected to the hanging plate on the lower four-way bend assembly by a tension spring.
[0009] Furthermore, the fixing assembly also includes a small pipe clamp and a large pipe clamp fixedly held on the first pipe clamp support plate, and a first pulley bracket and a second pulley bracket that are sequentially arranged on the middle gantry of the wire pulley bracket.
[0010] This utility model also proposes a three-stage fully free hose pulley system, including a mounting mechanism for the built-in wiring on a forklift, and further including... The hose system, which passes through the installation mechanism, includes a first high-pressure hose and a second high-pressure hose arranged in parallel. The first high-pressure hose is connected at both ends to a multi-way valve in the vehicle body and an upper four-way bend assembly located on the inner mast, respectively. The second high-pressure hose is connected at both ends to a multi-way valve in the vehicle body and a lower four-way bend assembly located on the inner mast, respectively.
[0011] Furthermore, the first high-pressure hose is fixedly clamped to the large hose by a small hose clamp and is slidably connected to the first pulley bracket; The second high-pressure hose is fixedly clamped to the first hose clamp support plate by the large hose clamp; the second high-pressure hose passes through the second pulley bracket provided on the first pulley bracket.
[0012] Furthermore, the hose system also includes a second hose assembly that passes sequentially through a second hose clamp support plate on the inner mast and a small hose clamp fixedly held on the second hose clamp support plate, and the second hose assembly is also fixed to the front cylinder pulley bracket on the front lifting cylinder.
[0013] Furthermore, the second hose assembly includes a first front cylinder hose and a second front cylinder hose symmetrically arranged. The two ends of the first front cylinder hose are respectively connected to the upper four-way bend assembly and the first partition joint on the fork carriage. The two ends of the second front cylinder hose are respectively connected to the lower four-way bend assembly and the second partition joint on the fork carriage. The first partition joint and the second partition joint are symmetrically arranged about the fork carriage.
[0014] Furthermore, the front cylinder pulley bracket is equipped with a hose protective cover.
[0015] The beneficial effects of this utility model's three-stage fully free-flowing hose pulley system with built-in electrical conduit are as follows: This utility model, through the coordinated arrangement of electrical conduits and hoses, not only avoids obstructing additional visibility but also provides better protection for the conduits and circuits, making them less prone to damage and greatly improving product quality. It also enhances the aesthetics of the gantry frame, ensuring the safety and reliability of the required oil and electrical circuits for the attachments. This reduces adverse effects such as damage or breakage of hoses and electrical wires caused by haphazard or improper installation, while also minimizing malfunctions caused by mutual interference between the oil conduits and wiring, thus extending the overall lifespan of the device.
[0016] In this invention, all oil line hoses and wiring are fixed by standardized components such as brackets and clamps, and their routing is clear, allowing for quick location of problems during later maintenance. Simultaneously, the use of components such as rubber plugs ensures the sealing of wiring connections and facilitates disassembly and replacement of wiring, thereby improving work efficiency.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0023] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0024] Example 1 Reference Figures 1-2 This is the first embodiment of the present invention. This embodiment provides an installation mechanism for built-in wiring on a forklift. The installation mechanism is disposed on a mast assembly, which includes an outer mast 1, a middle mast 2, an inner mast 3, and a fork carriage 4. It includes a fixing component, including a first pipe clamp support plate 11 disposed on the outer mast 1 and an electrical wire pulley bracket 17 disposed on the middle mast 2, for wiring and fixing the hoses and wires on the mast assembly, ensuring that their respective oil circuits are independent and coordinated, realizing coordinated operation of the device while effectively avoiding mutual interference of oil circuits, improving the stability and safety of the device; and; The wiring system includes an electrical conduit 10 fixedly clamped to the first pipe clamp support plate 11 by a wire clamp 14. The electrical conduit 10 is mounted on the electrical pulley bracket 17 and the first partition joint 31 on the fork carriage 4, allowing the electrical conduit 10 to move with the mast assembly without being damaged by the mast's movement. Simultaneously, the electrical conduit 10 does not separately occupy the mast's field of vision. Therefore, without additional obstruction of the field of vision, the system enables the three-level fully free mast forklift to be equipped with solenoid valve attachments and a fork monitoring camera. One end of the electrical conduit 10 passes through the first partition joint 31. The second rubber plug 32 is directly connected to the vehicle's power supply, and the other end of the electrical conduit 10 is connected to the attachment solenoid valve or the fork monitoring camera, thus effectively adapting to forklift scenarios that require frequent lifting and lowering and have functional expansion needs; for example, in large warehouses, when forklifts are stacking goods on high shelves, the stacking accuracy of the goods can be observed through the connected monitoring camera; when loading and unloading irregular goods in ports or factories, special attachments can be connected externally, and the attachment solenoid valve can be used to control the attachment's action to achieve stable clamping and handling of goods; in addition, the orderly pipeline design is also suitable for use in environments with complex working conditions such as dust and slight bumps, which can reduce the impact of harsh environments on the pipeline.
[0025] Example 2 Reference Figures 1-3 This is the second embodiment of the present utility model. The difference between this embodiment and the first embodiment is that the electrical conduit 10 also passes through the first rubber plug 18 provided on the lower four-way bend assembly 20 and is constrained to the second pipe clamp support plate 25 by the binding strap 33. The electrical conduit 10 is fixed to the third clamp support plate 27 by the dual-purpose pipe clamp 28. While ensuring that the electrical conduit 10 adapts to the expansion and contraction of the gantry in sync with the hose, the stability of the line is strengthened by multiple fixings of the rubber plug, the strapping 33 and the dual-purpose pipe clamp 28 to avoid shaking and wear. The conduit 10 is equipped with a wire locking plate 22, which is connected to the hanging plate on the lower four-way bend assembly 20 by a tension spring 21. The tension spring 21 provides a buffer margin for the conduit 10, so that even if the wire has poor elasticity, it can protect the wire from being pulled off when the gantry is raised quickly, thereby improving the safety of the device and extending its service life.
[0026] Example 3 Reference Figures 1-3 This is the third embodiment of the present invention. This embodiment provides a three-stage fully free hose pulley system, including an installation mechanism for the built-in wiring on a forklift. The fixing components also include a small pipe clamp 13 and a large pipe clamp 12 fixedly held on the first pipe clamp support plate 11, and a first pulley bracket 15 and a second pulley bracket 16 sequentially arranged on the middle mast 2 for the wire pulley bracket 17. This embodiment also includes... The hose system, through the installation mechanism, includes a first high-pressure hose 8 and a second high-pressure hose 9 arranged in parallel. The two ends of the first high-pressure hose 8 are respectively connected to the multi-way valve of the vehicle body and the upper four-way bend assembly 19 located on the inner mast 3; the two ends of the second high-pressure hose 9 are respectively connected to the multi-way valve of the vehicle body and the lower four-way bend assembly 20 located on the inner mast 3, forming a closed-loop transmission path of multi-way valve-hose-bend assembly-cylinder.
[0027] The first high-pressure hose 8 is fixedly clamped to the large hose 12 by the small hose clamp 13 and is slidably connected to the first pulley bracket 15. The first pulley bracket 15 is provided with 5 sets of pulleys. The first high-pressure hose 8 rotates by rolling friction with the pulleys. The second high-pressure hose 9 is fixedly clamped to the first hose clamp support plate 11 by the large hose clamp 12. The layered and graded clamping effectively avoids mutual interference between hoses, improves stability, and also ensures the flexibility of the hose as it moves up and down with the gantry. The second high-pressure hose 9 passes through the second pulley bracket 16 located on the first pulley bracket 15. The second pulley bracket 16 is equipped with 4 sets of pulleys. The second high-pressure hose 9 rotates by rolling friction with the pulleys. At this time, the first high-pressure hose 8 and the second high-pressure hose 9 are stacked in parallel and do not interfere with each other.
[0028] In the first high-pressure hose 8, the oil circuit is arranged as follows: multi-way valve → first high-pressure hose 8 → small hose clamp 13 → first hose clamp support plate 11 → large hose clamp 12 → first pulley bracket 15 → upper four-way bend assembly 19. In the second high-pressure hose 9, the oil circuit is arranged as follows: multi-way valve → second high-pressure hose 9 → large hose clamp 12 → first hose clamp support plate 11 → second pulley bracket 16 → lower four-way bend assembly 20.
[0029] Example 4 Reference Figures 1-3 This is the fourth embodiment of the present utility model. The difference between this embodiment and the third embodiment is that the hose system also includes a second hose assembly that passes through the second hose clamp support plate 25 on the inner gantry 3 in sequence and the small hose clamp 13 fixedly clamped on the second hose clamp support plate 25. The second hose assembly is also fixed to the front cylinder pulley bracket 24 on the front lifting cylinder 5. The front cylinder pulley bracket 24 is provided with 4 sets of pulleys. The second hose assembly includes a first front cylinder hose 26 and a second front cylinder hose 29 arranged symmetrically. The two ends of the first front cylinder hose 26 are respectively connected to the upper four-way bend assembly 19 and the first partition joint 31 on the fork carriage 4. The two ends of the second front cylinder hose 29 are respectively connected to the lower four-way bend assembly 20 and the second partition joint 30 on the fork carriage 4. The first partition joint 31 and the second partition joint 30 are arranged symmetrically about the fork carriage 4. In the first front cylinder hose 26, the oil passage route is as follows: upper four-way bend assembly 19 → first front cylinder hose 26 → small pipe clamp 13 → front cylinder pulley bracket 24 → second partition joint 30. In the second front cylinder hose 29, the oil passage route is as follows: lower four-way bend assembly 20 → second front cylinder hose 29 → small pipe clamp 13 → front cylinder pulley bracket 24 → first partition joint 31.
[0030] The front cylinder pulley bracket 24 is equipped with a hose protective cover 23, which effectively prevents the hose or electrical conduit 10 from coming off the front cylinder pulley bracket 24 when it rubs against the pulley, thus improving the safety and stability of the device.
[0031] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
