Abstract
Description
Technical Field
[0001] This utility model relates to the field of engineering machinery technology, and in particular to a novel pipeline layout structure for the excavating end of an excavator loader. Background Technology
[0002] The statements in this section are merely background information relating to this disclosure and do not necessarily constitute prior art.
[0003] Many domestic manufacturers are currently engaged in the research and development of backhoe loaders. However, most manufacturers directly connect hoses to the multi-way valve when dealing with the pipeline layout of the excavator end. This structure leads to inconsistent hose lengths, further causing technical problems such as different turning radii during the left and right swing of the skid frame, and chaotic hose movement trajectories leading to wear. Once a hydraulic hose ruptures, it can cause property damage or even personal injury. Currently, the solution adopted by major manufacturers is to add cable chains or protective sleeves, but this method is very costly, and even after forcibly binding the pipeline, the problem of inconsistent hose movement trajectories cannot be solved, leading to excessive wear of the cable chains and increased maintenance costs in the later stages. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a novel pipeline layout structure for the excavator loader's excavation end. By cooperating with different valve plates of the excavator valve, the final effect is achieved, ensuring that the length of the hose leading from the excavator valve to the excavation end is consistent and the radius of rotation is consistent, thereby reducing the cost of later maintenance and upkeep.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A novel excavator loader excavator end pipeline layout structure includes an excavator multi-way valve (1) and a hose (2) connected to the excavator end, and also includes a steel pipe (3). One end of the steel pipe (3) is connected to the oil outlet of the excavator multi-way valve (1), and the other end extends to both sides of the excavator multi-way valve (1) to form symmetrical oil ports (4).
[0007] Furthermore, the symmetrical oil ports (4) are located in the same vertical plane and are symmetrically distributed with respect to the central axis of the excavation multi-way valve (1).
[0008] Furthermore, the steel pipe (3) includes a transverse pipe section (31) and a longitudinal pipe section (32). The transverse pipe section (31) is vertically connected to the excavation multi-way valve (1), and the longitudinal pipe section (32) extends horizontally to both sides to form symmetrical oil ports (4).
[0009] Furthermore, the hose (2) is detachably connected to the symmetrical oil port (4).
[0010] Furthermore, the symmetrical oil outlets (4) include the first to sixth oil outlets on the left and the seventh to twelfth oil outlets on the right; the first to sixth oil outlets and the seventh to twelfth oil outlets are all fixed together by steel pipe clamps (6).
[0011] Furthermore, cable tie clamps (5) are provided on both sides of the excavation multi-way valve (1), and the hose (2) is fixed to the sliding frame by the cable tie clamps (5).
[0012] Furthermore, the sliding frame includes an upper slide rail and a lower slide rail.
[0013] Compared with the prior art, the novel pipeline layout structure for the excavating end of an excavator loader provided by this utility model has the following beneficial effects:
[0014] 1. After the excavation multi-way valve is connected to the steel pipe leading to both sides of the excavation multi-way valve, the oil outlet of the steel pipe is on the same vertical line. This ensures that the hose length from the excavation valve to the excavation end is consistent, the turning bending radius is consistent, and the movement trajectory of the hose is consistent. Only one cable clamp needs to be added on both sides to ensure the regularity of the pipeline when the sliding frame slides.
[0015] 2. Without altering the existing stable hydraulic system, a simple change to the pipeline layout cleverly solves the common problems of competing vehicles on the same platform and of the same type. It also achieves control over pipeline movement without incurring higher costs, thus solving the problems of pipeline wear or drag chain sheath wear while ensuring the safety of personnel and property, achieving a win-win situation.

[0028] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0029] Example 1
[0030] In one typical embodiment of this application, a novel pipeline layout structure for the excavating end of an excavator loader is provided, such as... Figure 1-5As shown, the new excavator loader's excavation end piping layout includes an excavation multi-way valve (1) and a flexible hose (2) connected to the excavation end, as well as a steel pipe (3). One end of the steel pipe (3) is connected to the oil outlet of the excavation multi-way valve (1), and the other end extends to both sides of the excavation multi-way valve (1) to form symmetrical oil ports (4). Specifically, the inner diameter of the steel pipe (3) is 5mm. By setting the steel pipe, the length of the flexible hose leading from the excavation multi-way valve to the excavation end is consistent, solving the problems of different turning radii and chaotic movement trajectories caused by inconsistent hose lengths, thereby reducing hose wear and improving the safety and reliability of the equipment.
[0031] Specifically, such as Figure 2 The symmetrical oil ports (4) are located in the same vertical plane and are symmetrically distributed with respect to the central axis of the excavation multi-way valve (1). The design of the symmetrical oil ports ensures that the hose has the same radius of rotation during the left and right swing of the sliding frame, further guaranteeing the stability and consistency of the hose movement.
[0032] Specifically, such as Figure 2-5 The steel pipe (3) includes a transverse pipe section (31) and a longitudinal pipe section (32). The transverse pipe section (31) is vertically connected to the excavation multi-way valve (1), and the longitudinal pipe section (32) extends horizontally to both sides to form symmetrical oil ports (4). The steel pipe includes a transverse pipe section and a longitudinal pipe section, which has a compact structure, is easy to install and maintain, and improves the overall aesthetics of the equipment.
[0033] The symmetrical oil outlets (4) include the first to the sixth oil outlets on the left and the seventh to the twelfth oil outlets on the right. The first to the sixth oil outlets and the seventh to the twelfth oil outlets are all fixed together by steel pipe clamps (6). The vertical distance between two adjacent oil outlets from the first to the sixth oil outlet is 33mm.
[0034] The excavation multi-way valve (1) includes the first valve to the eighth valve arranged from right to left. The first valve and the eighth valve are connected by a support leg and are not connected to the steel pipe. The second valve to the seventh valve are all led out of the oil port through the steel pipe (3).
[0035] Specifically, such as Figure 1 The hose (2) is detachably connected to the symmetrical oil ports (4). The detachable connection between the hose and the symmetrical oil ports facilitates replacement and maintenance, reducing the cost of later maintenance and upkeep.
[0036] The excavator multi-way valve (1) is equipped with cable clamps (5) on both sides. The hose (2) is fixed to the sliding frame through the cable clamps (5). The hose (2) maintains a consistent trajectory when sliding with the sliding frame. The cable clamps on both sides of the excavator multi-way valve can effectively fix the hose and prevent it from shaking or falling off during operation, further improving the safety and stability of the equipment.
[0037] like Figure 6 The sliding frame includes an upper sliding rail and a lower sliding rail, and the sliding frame can slide left and right through the upper and lower sliding rails.
[0038] like Figure 7 The working principle of this utility model is as follows:
[0039] During operation, hydraulic oil flows from the excavation multi-way valve, guided by steel pipes, and flows evenly from symmetrical oil ports to the hose. Because the symmetrical oil ports are located in the same vertical plane and symmetrically distributed with respect to the central axis of the excavation multi-way valve, the hose has the same radius of rotation during the left-right swing of the sliding frame, ensuring the stability and consistency of the hose's movement. Simultaneously, the hose is fixed to the sliding frame by cable clamps, effectively preventing the hose from shaking or falling off during operation, further improving the safety and stability of the equipment. The overall structure is compact and rationally designed, not only solving the problems of inconsistent hose lengths leading to different radii of rotation and chaotic movement trajectories in existing technologies, but also reducing subsequent maintenance costs.
[0040] The new excavator loader's excavating end pipeline layout structure provided by the utility model increases the steel pipe so that the oil outlets are all on the same vertical line. This ensures that the hose length from the excavator valve to the excavating end is consistent and the turning radius is consistent. The hose will not be worn due to random movement when the skid frame slides. Compared with competing vehicles, it is cheaper and more affordable to add protective sleeves and drag chains. Later maintenance is more convenient and cheaper.
[0041] In the description of this specification, the terms "connection", "installation", "fixing", "setting", etc. are interpreted in a broad sense. For example, "connection" can be a fixed connection or an indirect connection through an intermediate component without affecting the relationship between components and the technical effect. It can also be an integral connection or a partial connection. In such cases, those skilled in the art can understand the specific meaning of the above terms in this utility model or utility model according to the specific circumstances.
[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
