[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model is described below with reference to specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are merely exemplary and not intended to limit the scope of the present utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0028] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0029] Traditional mast hydraulic circuit layouts are typically diagonal or transverse, which can easily obstruct the driver's view during operation. This is especially true when the mast is raised to a certain height, which can seriously affect the driver's handling of goods and may even lead to safety accidents, impacting the user experience and hindering the promotion and application of the aforementioned mast hydraulic circuit layouts on forklifts.
[0030] To solve the above technical problems, such as Figures 1 to 7 As shown, a wide-view mast hydraulic circuit structure mainly consists of multiple hydraulic pipes 1 and mounting components 2 for installing the hydraulic pipes 1. In order to increase the visible field of view of the mast, in this embodiment, the multiple hydraulic pipes 1 are arranged in a straight line along the longitudinal direction of the mast, minimizing the obstruction of the hydraulic pipes 1 in the width direction of the forklift. That is, when viewed from the front or rear of the forklift, only the cross-section of a single hydraulic pipe 1 can be seen, thereby widening the field of view of the forklift mast and reducing the obstruction of the driver's vision. Specifically, to fix the installation position of the oil pipe 1 and prevent it from shifting or shaking during use, the installation assembly 2 in this embodiment mainly consists of a mounting bracket 2-1, a mounting pulley 2-2, and a mounting shaft 2-3. The mounting shaft 2-3 can be fixedly installed on the mounting bracket 2-1 by welding or other means. The mounting pulley 2-2 is then installed on the mounting shaft 2-3. A locking limiter 2-5 is installed on the mounting shaft 2-3 outside the mounting pulley 2-2 to limit its displacement. The locking limiter 2-5 is a simple, economical, and practical locking nut. The locking nut secures the mounting pulley 2-2 to the mounting shaft 2-3, preventing it from sliding in the axial direction of the mounting shaft 2-3, thereby ensuring the installation position of the oil pipe 1. The mounting shaft 2-3 can be a pin, and correspondingly, the center of the mounting pulley 2-2 has a pin hole for the pin to pass through. To further prevent the axial movement of the aforementioned installation pulley 2-2 during operation, thereby ensuring the fixation of the installation position of the aforementioned oil pipe 1, in this embodiment, a retaining ring 2-4 is installed between the aforementioned installation pulley 2-2 and the locking limit member 2-5.
[0031] Multiple oil pipes 1 are mounted on an inlet mounting plate 4 at one end and an outlet mounting plate 5 at the other end. The inlet mounting plate 4 is used to fix the forklift to the outer mast, and the outlet mounting plate 5 is used to fix the forklift to the inner mast and moves up and down with the inner mast. Both the inlet mounting plate 4 and the outlet mounting plate 5 are also equipped with partition joints 6 for connecting and communicating with the oil pipes 1. In this embodiment, the oil pipe inlets are uniformly arranged close to the oil outlet side of the multi-way valve, thereby shortening the length of the partition joints 6 between the oil pipes 1 and the multi-way valve outlets. The oil pipe outlets are uniformly arranged on the opposite side of the multi-way valve outlet. The inlet mounting plate 4 is fixed to the front side of the outer mast crossbeam and remains stationary; the outlet mounting plate 5 is fixed to the inner mast and moves up and down with the inner mast. Throughout the process, the oil pipes 1 remain arranged in a straight line along the longitudinal direction of the mast, minimizing obstruction of the oil pipes 1 in the width direction of the forklift and enhancing the user experience. The aforementioned baffle joint 6 is adjustable, allowing for adjustment of the pre-tension of the oil pipe 1. After a period of use, if the oil pipe 1 becomes stretched, its length can be fine-tuned by adjusting the installation position of the baffle joint to prevent it from becoming too long and slipping out of the installation pulley 2-2. If the oil pipe 1 remains too long even when the baffle joint is adjusted to its limit, it indicates severe deformation, significantly reducing its pressure resistance and posing a safety hazard, necessitating replacement of the oil pipe 1. The baffle joint 6 avoids complex piping designs caused by limitations in oil port location, reducing both design and installation difficulty.
[0032] In this embodiment, there are two mounting pulleys 2-2, which are installed along the length of the mounting frame 2-1. The mounting frame 2-1 has two pulley mounting positions 2-1-1 for mounting the pulleys 2-2. The two mounting pulleys 2-2 guide the oil pipe 1, preventing the oil pipe 1 from becoming tangled during its up-and-down movement. The mounting frame 2-1 is L-shaped, and the two pulley mounting positions 2-1-1 are spaced apart to form a viewing window 2-1-2. Compared to a flat mounting frame, the viewing window 2-1-2 of the mounting frame 2-1 in this embodiment provides the operator with a wider field of vision, thereby further ensuring the safety of the forklift during operation. The aforementioned installation pulley 2-2 forms an installation groove 2-2-1. A limiting position is formed between the top of the aforementioned mounting bracket 2-1 and the aforementioned installation groove 2-2-1. This limiting position guides the aforementioned oil pipe 1 and prevents the oil pipe 1 from misaligning, thus protecting the oil pipe 1. If the aforementioned mounting bracket 2-1 did not have the top plate structure in this embodiment, once the aforementioned oil pipe 1 is stretched under external force, it is very easy for it to slip out of the aforementioned installation groove 2-2-1. During this process, if the gantry is still in the lifting state, it may cause compression of the oil pipe 1, leading to the oil pipe 1 breaking and causing danger.
[0033] The number and dimensions of the aforementioned mounting grooves 2-2-1 are matched with the number and dimensions of the aforementioned oil pipes 1. The purpose is to embed the oil pipes 1 within the mounting grooves 2-2-1, thereby organizing and guiding the oil pipes 1 and preventing misalignment during their vertical movement. The aforementioned mounting pulleys 2-2 are made of Teflon (or similar) material, possessing high lubricity, eliminating the need for bearings, reducing processing and installation difficulty, and their excellent corrosion and wear resistance reduces subsequent maintenance costs.
[0034] To further organize the aforementioned oil pipes 1, pipe clamps 3 are installed on multiple oil pipes 1 in this embodiment. Similarly, the pipe clamps 3 are arranged in a straight line, primarily to avoid obstructing the forklift's view. The pipe clamps 3 also secure the oil pipes, preventing displacement or loosening due to vibration or external forces during operation, thus ensuring the stability of the oil pipes 1. The straight-line design of the pipe clamps 3 facilitates installation and adjustment, allowing for quick securing of multiple oil pipes 1, and enabling rapid disassembly when maintenance or replacement of the oil pipes 1 is required. The pipe clamps 3 have multiple clamp holes 3-1 that fit the oil pipes 1, through which the oil pipes 1 pass.
[0035] This embodiment presents a wide-view mast hydraulic circuit structure. This ingenious structure arranges multiple hydraulic pipes 1 in a straight line along the longitudinal direction of the mast, i.e., the front-to-back direction of the forklift (the position of the forklift's forks is the front, and vice versa). This minimizes the obstruction of the hydraulic pipes 1 in the width direction of the forklift. That is, only the cross-section of a single hydraulic pipe 1 can be seen from the front or rear of the forklift. This widens the field of vision of the forklift mast, reduces obstruction to the driver's view, improves the safety and efficiency of operation, enhances the user experience, and is conducive to the promotion and application of the above-mentioned wide-view mast hydraulic circuit structure in the field of forklift technology.
[0036] The wide-view mast hydraulic circuit structure described in the above embodiments can be applied to, but is not limited to, forklifts.
[0037] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention; therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
