Description

Technical Field

[0001] This application relates to the field of engineering machinery technology, specifically to an integrated hydraulic pipeline layout device for the telescopic boom of engineering equipment. Background Technology

[0002] In the field of engineering equipment, telescopic booms, as core operating components, are widely used in various types of equipment such as cranes, excavators, and aerial work platforms. They mainly achieve diverse operational needs through the nested telescopic and luffing movements of multiple boom sections, in conjunction with end-effector hydraulic tools (such as hydraulic hammers, grab buckets, and work platforms). The precise execution of this series of movements relies on multiple hydraulic lines laid inside the telescopic boom.

[0003] In existing technologies, the hydraulic lines inside telescopic booms are mostly designed with a decentralized, independent layout, meaning that each line is directly laid on its corresponding area on the boom without a unified constraint structure. However, during the operation of engineering equipment, the boom inevitably vibrates, and the multiple boom sections will generate relative displacement during telescopic movement. This makes it easy for continuous friction and motion interference to occur between the decentralized hydraulic lines and the inner wall of the boom, as well as between the lines themselves.

[0004] Under prolonged operating conditions, the outer protective layer of hydraulic pipelines will gradually thin and even break due to friction and wear, leading to damage and rupture of the pipeline itself and ultimately causing hydraulic oil leakage. This not only causes malfunctions such as pressure imbalance and operation interruption in the equipment's hydraulic system, increasing equipment maintenance costs and downtime, but also pollutes the working environment due to hydraulic oil leakage, failing to meet relevant environmental protection requirements. Furthermore, it poses a potential risk of safety accidents, seriously affecting the operational reliability and safety of engineering equipment.

[0005] Therefore, this application provides an integrated hydraulic pipeline layout device for the telescopic boom of engineering equipment to solve the above-mentioned problems. Utility Model Content

[0006] This application provides an integrated hydraulic pipeline layout device for the telescopic boom of engineering equipment, aiming to solve the problems mentioned in the background art, such as the existing hydraulic pipelines being scattered and independently arranged, which are prone to frictional interference caused by equipment vibration and boom telescopic movement, resulting in wear and rupture of the outer layer of the pipelines, leading to hydraulic oil leakage, and thus causing equipment failure and environmental pollution.

[0007] To achieve the above objectives, this application provides the following technical solution: a hydraulic pipeline integrated layout device for a telescopic boom of engineering equipment, comprising a fixed base fixedly installed at the root of the telescopic boom or a non-moving end of a boom section, and a movable plate hinged to the fixed base. The other end of the fixed base is provided with a fixing member for locking the movable end of the movable plate. Multiple sets of partitions located between the movable plate and the fixed base are used to space the hydraulic pipes. Each partition includes an arc-shaped clamping plate fixed to one end of the movable plate opposite to the fixed base, which adapts to the curvature of the outer wall of the hydraulic pipe. Opening the movable plate allows the hydraulic pipe to be placed into the arc-shaped clamping plate on the fixed base. Closing the movable plate locks the movable end of the movable plate, causing the arc-shaped clamping plate on the fixed base to engage the hydraulic pipe. Combined with the equally spaced partitions, this achieves the equally spaced arrangement and position locking of the hydraulic pipes.

[0008] Preferably, to facilitate the arrangement of the separators, the fixing base has a "U"-shaped structure. This simplifies the installation and arrangement process of the separators, improves the ease of installation and the standardization of their layout, and reduces the overall assembly difficulty of the device.

[0009] Preferably, to give the arc-shaped clamping plate a certain degree of elasticity, the arc-shaped clamping plate is provided with a hollow groove. This gives the arc-shaped clamping plate elasticity, adapting to the clamping requirements of hydraulic pipes of different diameters, while improving the clamping buffer effect and avoiding hard compression damage to the outer wall of the hydraulic pipe.

[0010] Preferably, to avoid hard friction between the arc-shaped clamping plate and the hydraulic pipe: an elastic pad, which is a silicone rubber pad, is fixedly connected to the inner side of the arc-shaped clamping plate. This elastic pad design isolates the arc-shaped clamping plate from hard contact with the hydraulic pipe, alleviates frictional damage caused by vibration, further protects the outer protective structure of the hydraulic pipe, and extends the service life of the hydraulic pipe.

[0011] Preferably, the fixing component includes an L-shaped locking plate fixedly connected to the movable end of the movable plate and a slot formed on the fixed seat for fitting the L-shaped locking plate. This enables quick locking and fixing of the movable end of the movable plate to the fixed seat, improves the convenience of opening and closing the movable plate, ensures the stability of the movable plate after locking, and prevents the hydraulic pipe from loosening.

[0012] Preferably, a shock-absorbing pad is fixedly connected to the end of the fixed base away from the movable plate. This reduces the vibration force transmitted from the engineering equipment to the fixed base, reduces the impact of vibration on the hydraulic pipes and the overall device, reduces frictional losses in the pipeline caused by vibration, and improves the operational stability of the device.

[0013] This application uses multiple sets of equally spaced separators to arrange hydraulic pipes in an orderly manner, avoiding messy shaking and friction interference, improving the installation stability of hydraulic pipes, reducing the risk of pipe wear and breakage, and ensuring reliable equipment operation and environmental safety.

[0014] This application utilizes an elastic pad design to isolate the rigid contact between the curved plate and the hydraulic pipe, mitigating frictional damage caused by vibration, further protecting the outer protective structure of the hydraulic pipe, and extending the service life of the hydraulic pipe.

[0017] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0018] This embodiment provides an integrated hydraulic pipeline layout device for a telescopic boom of engineering equipment, such as... Figure 1-3As shown, the integrated arrangement device includes a fixed base 1 fixedly installed at the root of the telescopic boom or a non-moving end of a boom section, and a movable plate 2 hinged to the fixed base 1. The other end of the fixed base 1 is provided with a fixing member 3 for locking the movable end of the movable plate 2. Multiple sets of separators 4 are located between the movable plate 2 and the fixed base 1 for arranging hydraulic pipes at intervals. Each separator 4 includes an arc-shaped clamping plate 41 fixed to one end of the movable plate 2 opposite to the fixed base 1 to adapt to the curvature of the outer wall of the hydraulic pipe. The multiple sets of separators 4, arranged at equal intervals, can arrange the hydraulic pipes in an orderly manner, avoiding disorderly movement and friction interference, improving the installation stability of the hydraulic pipes, reducing the risk of pipe wear and breakage, and ensuring reliable equipment operation and environmental safety. Opening the movable plate 2 allows the hydraulic pipe to be placed into the arc-shaped clamping plate 41 on the fixed base 1. After closing the movable plate 2, the movable end of the movable plate 2 is locked by the fixing piece 3, so that the movable plate 2 and the corresponding arc-shaped clamping plate 41 on the fixed base 1 engage the hydraulic pipe. With the help of the equally spaced separators 4, the hydraulic pipe is arranged at equal intervals and its position is locked.

[0019] To facilitate the placement of the partition element 4, the fixing base 1 has a "U"-shaped structure. This simplifies the installation and placement process of the partition element 4, improves the ease of installation and the standardization of its arrangement, and reduces the overall assembly difficulty of the device. The U-shaped structure of the fixing base 1 provides a stable mounting carrier and arrangement space for the partition element 4 through its opening and internal space, making it easy to quickly fix the partition element 4 at the corresponding positions on the fixing base 1 at preset intervals without the need for additional installation structures.

[0020] To give the arc-shaped clamping plate 41 a certain degree of elasticity, a perforated groove 411 is provided on the arc-shaped clamping plate 41. This gives the arc-shaped clamping plate 41 elasticity, adapting to the clamping requirements of hydraulic pipes of different diameters, while improving the clamping buffer effect and avoiding hard compression damage to the outer wall of the hydraulic pipe. The perforated groove 411 can weaken the rigidity of the arc-shaped clamping plate 41 itself, allowing it to slightly expand and contract according to the diameter of the hydraulic pipe when clamping it, achieving a tight clamping while retaining a certain elastic margin.

[0021] To prevent hard friction between the arc-shaped clamping plate 41 and the hydraulic pipe, an elastic pad 42, made of silicone rubber, is fixedly connected to the inner side of the arc-shaped clamping plate 41. This isolates the arc-shaped clamping plate 41 from hard contact with the hydraulic pipe, alleviates frictional damage caused by vibration, further protects the outer protective structure of the hydraulic pipe, and extends the service life of the hydraulic pipe. The elastic pad 42 is in direct contact with the outer wall of the hydraulic pipe. When the equipment vibrates or the boom extends or retracts, causing relative movement, the elastic pad 42 absorbs the impact force through its own elastic deformation, preventing direct hard friction between the arc-shaped clamping plate 41 and the hydraulic pipe.

[0022] The fixing component 3 includes an L-plate 31 fixedly connected to the movable end of the movable plate 2 and a slot 32 formed on the fixing base 1 for fitting the L-plate 31. This allows for quick snap-fit ​​fixing of the movable end of the movable plate 2 to the fixing base 1, improving the ease of opening and closing the movable plate 2, ensuring the stability of the movable plate 2 after locking, and preventing the hydraulic pipe from loosening. After closing the movable plate 2, the L-plate 31 is snapped into the slot 32. Through the snap-fit ​​engagement between the L-plate 31 and the slot 32, the movable end of the movable plate 2 is quickly fixed to the fixing base 1.

[0023] A vibration damping pad 11 is fixedly connected to the end of the fixed base 1 away from the movable plate 2. This damping pad reduces the vibration force transmitted from the engineering equipment to the fixed base 1, decreases the impact of vibration on the hydraulic pipes and the overall device, reduces frictional losses in the pipelines caused by vibration, and improves the operational stability of the device. The vibration damping pad 11 is located between the fixed base 1 and the engineering equipment. When the equipment vibrates, the damping pad 11 absorbs vibration energy through the buffering properties of its material, blocking the transmission of vibration force to the fixed base 1 and the internal hydraulic pipes.

[0024] It should be noted that many of the standard parts used in this application are available on the market, while non-standard parts can be specially customized. The connection method used in this application is also a very common method in the mechanical field, and will not be described in detail here.

[0025] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
