[0002] In coal mining and other operations, hydraulic supports are crucial support equipment, and their hydraulic hoses are used to transport hydraulic oil and other working media. However, existing hydraulic hoses often come into direct contact with the structural components of the hydraulic supports during operation.

This not only affects production efficiency but may also cause safety accidents, and frequent replacement of hydraulic hoses increases maintenance costs.

[0003] Current protective measures on the market are ineffective and cannot effectively solve the problem of hydraulic hose wear. Therefore, there is an urgent need for a more efficient protective device. Utility Model Content

[0036] In coal mining, hydraulic supports are crucial support equipment used to support and protect the working face in the mine. Hydraulic supports contain hydraulic hoses used to transport hydraulic oil and other working media. However, due to frequent equipment movement, these hydraulic hoses often come into direct contact with the structural components of the supports, leading to hose wear and even damage. This is mainly manifested in scraping and squeezing of the hydraulic hoses, which not only affects the normal operation of the hydraulic system and reduces production efficiency but may also lead to equipment failure or safety accidents, increase maintenance costs, and pose safety hazards. Existing protective measures cannot effectively prevent direct contact between the hoses and structural components, causing these parts to wear down faster due to friction and squeezing.

[0037] In view of this, this application provides a convenient hydraulic support hose protection device, which effectively protects the hydraulic hose while providing multi-dimensional and flexible rotation and adjustment capabilities, ensuring that the hose can work flexibly and smoothly in different environments, solving the problem of wear and damage to the hydraulic hose caused by direct contact between the hose and the hydraulic support structural components, and extending the service life of the hydraulic hose.

[0038] Please refer to Figure 1 and Figure 2 , Figure 1 A schematic diagram of the structure of the portable hydraulic support hose protection device provided in some embodiments of this application when it is in the assembled state; Figure 2 This is a schematic diagram of the structure of the portable hydraulic support hose protection device provided in some embodiments of this application when it is in working condition.

[0039] This application provides a portable hydraulic support hose protection device, including at least one protective body 1. The protective body 1 includes a base 11, an angle adjusting member 12, and a hose fixing assembly 13. The base 11 is fixedly connected to the hydraulic support 2, and the base 11 encloses a rotating cavity. At least a portion of the angle adjusting member 12 is embedded inside the rotating cavity, and the angle adjusting member 12 is rotatably connected to the rotating cavity to adjust the installation position and angle of the hydraulic hose relative to the hydraulic support 2. The hose fixing assembly 13 is disposed on the side of the angle adjusting member 12 away from the base 11. The hose fixing assembly 13 includes at least two fixing members 131 and a locking part 132. Each fixing member 131 encloses a fixing cavity, which can circumferentially fix the hose. The locking part 132 is used to lock each fixing member 131.

[0040] The base 11 is used to fix the entire device to the structural components of the hydraulic support 2. The hose fixing assembly 13 and each fixing member 131 can easily place the hose when it is open, and when closed, each fixing member 131 cooperates to wrap the hydraulic hose and fix its position by locking member.

[0041] When installing the hose protection device: First, fix the base 11 to the target position of the hydraulic support 2 using bolts or other fasteners. Then, adjust the installation position and angle of the hydraulic hose relative to the hydraulic support 2 using the angle adjustment component 12, according to the position and direction of the hydraulic hose.

[0042] When fixing the hydraulic hose, open the fixing cavity of the fixing member 131, place the hydraulic hose in the fixing cavity, and finally use the locking part 132 to lock each fixing member 131 to fix the hydraulic hose.

[0043] The portable hydraulic support hose protection device provided in this application protects the hydraulic hose by installing a protective device between the hydraulic hose and the hydraulic support 2 structural component. The hose fixing component 13 effectively wraps the hydraulic hose, reducing wear. The angle adjustment component 12 provides multi-dimensional and flexible rotation and adjustment capabilities to ensure that the hose can work smoothly in different environments, thereby achieving the purpose of protection.

[0044] In one specific embodiment, the angle adjustment component 12 includes a rotating body 121 and a connecting rod 122. The connecting rod 122 is fixedly connected to the rotating body 121 on the side opposite to the base 11. At least a portion of the rotating body 121 is rotatably connected to the rotating cavity. The two ends of the connecting rod along the first direction X are respectively fixedly connected to the rotating body 121 and the hose fixing assembly 13.

[0045] Rotating body 121 can be Figure 1 The rotating body 121 is rotatably connected to the rotating cavity, which is a spherical cavity, a hemispherical cavity, an elliptical spherical cavity, etc., and the spherical cavity is a spherical cavity, a hemispherical cavity, an elliptical spherical cavity, etc.

[0046] The connecting rod 122 provides support and connects to the rotating body 121 to facilitate adjustment of the installation angle of the hose fixing assembly 13. The rotating body 121 provides flexible rotation in multiple directions, enabling the device to adapt to different working conditions. The spherical universal joint seat is fixed on the base 11 to support the spherical universal joint.

[0047] The connecting rod 122 can be a cylindrical rod, a square rod, or a frame structure. One end of the rod is fixedly connected to the rotating body 121, and the other end is fixedly connected to the hose fixing assembly 13. The connecting rod 122 can drive the hose fixing assembly 13 to move synchronously, so as to adjust the position and angle of the hose fixing assembly 13.

[0048] Thus, by rotating the hose fixing assembly 13 and / or the angle adjusting member 12, the angle adjusting member 12 can adjust the angle of the hose fixing assembly 13 through the rotational connection between the rotating body 121 and the rotating cavity, thereby adapting to different working conditions, avoiding contact between the hydraulic hose and the hydraulic support 2, and preventing wear of the hydraulic hose.

[0049] In one specific embodiment, the hose fixing assembly 13 includes at least two fixing members 131 distributed circumferentially. Each fixing member 131 has a locking structure and an inner cavity. All the locking structures are engaged and positioned so that all the inner cavities form a fixing cavity.

[0050] The fastener 131 can be half, one-third, or one-quarter of the original size. All fasteners 131 are circumferentially assembled to form the hose fixing assembly 13. The inner cavity of the fastener 131 can be semi-circular or fan-shaped. The inner cavities of all fasteners 131 cooperate to form a fixing cavity. The various locking structures cooperate to position the entire inner cavity to form a fixing cavity, thereby forming a structure for circumferentially fixing the hydraulic hose. This achieves local structural protection of the outer circumferential surface of the hydraulic hose.

[0051] like Figure 2 and Figure 3 As shown. The hose fixing assembly 13 includes a first fixing member and a second fixing member, which are distributed along a first direction X. The first fixing member has a first inner cavity and a first locking structure on its outer wall. The second fixing member has a second inner cavity and a second locking structure on its outer wall. The first locking structure and the second locking structure cooperate to form a fixing cavity that wraps around the hydraulic hose. The locking member 134 then locks and fixes the first locking structure and the second locking structure.

[0052] Furthermore, the hose fixing assembly 13 includes a first fixing member and a second fixing member distributed along the second direction Y. The first fixing member has a first inner cavity inside and a first locking structure on its outer wall. The second fixing member has a second inner cavity inside and a second locking structure on its outer wall. The first locking structure and the second locking structure cooperate to form a fixing cavity between the first inner cavity and the second inner cavity for fixing the hydraulic hose. The first fixing member and the second fixing member can be opened to facilitate the removal of the hydraulic hose.

[0053] In this embodiment, the first fixing member and the second fixing member of the hose fixing assembly 13 are distributed along the second direction Y, which intersects with the first direction X.

[0054] For example Figure 2 For example, the first direction can be the vertical direction, and the second direction can be the direction that forms an angle with the vertical direction, such as the horizontal direction. The first and second fixing parts cooperate to form a protective structure for circumferentially fixing the hydraulic hose, so as to ensure that the fixing part 131 is tightly attached to part of the outer circumferential surface of the hydraulic hose, thereby improving the reliability of the hydraulic hose installation.

[0055] When installing the hydraulic hose, open the first and second fixing parts, place the hydraulic hose into the first and second inner cavities, close the first and second fixing parts, and use bolts or other locking parts 134 to tighten one side of the first and second fixing parts to complete the fixing of the hydraulic hose.

[0056] Furthermore, in order to effectively protect the hydraulic hose, the fixing member 131 can also be provided with at least two elastic sleeves 133. The elastic sleeves 133 are fixedly connected to the inner cavity of each fixing member 131. The elastic sleeves 133 can be elastic sleeves, such as rubber sleeves, silicone sleeves, etc., and can be bonded and fixed to the inner wall of the fixing member 131. The elastic sleeves 133 wrap around the hydraulic hose, providing buffering force and reducing wear. In conjunction with the circumferentially distributed elastic sleeves 133, the hydraulic hose can be wrapped in all directions in the circumferential direction, avoiding direct contact between the hydraulic hose and other components of the hydraulic support 2, effectively protecting the hydraulic hose, greatly reducing wear, and significantly extending the service life of the hydraulic hose.

[0057] In this embodiment, the elastic sleeve 133 makes elastic contact with the hydraulic hose, and the elasticity of the elastic sleeve 133 absorbs the vibration and friction generated during the operation of the hydraulic equipment, preventing friction damage to the hydraulic hose. At the same time, the spherical universal joint formed by the rotating body 121 and the rotating cavity can achieve multiple angle adjustments to adapt to different working conditions.

[0058] like Figure 4As shown. To improve the rotational fit accuracy between the first and second fixing members of the hose fixing assembly 13, a limiting structure can be provided at the transition ends of the two fixing members 131. Specifically, the first transition end of the first fixing member is provided with a plurality of limiting blocks 136 distributed along the third direction Z, with the limiting blocks 136 spaced apart. The second connecting end of the second fixing member is provided with a plurality of limiting grooves 135 distributed at intervals, and the limiting blocks 136 are rotatably connected to the limiting grooves 135. The hose fixing assembly 13 also includes a rotating shaft 137, which passes through the base 11 along the third direction Z and passes through each limiting groove 135 and each limiting block 136. The rotating shaft 137 allows the first and second fixing members to rotate around it.

[0059] When the first and second fixing members rotate around the rotating shaft 137, the limiting block 136 can be limited by the limiting groove 135 to improve the motion accuracy between the first and second fixing members and ensure that the first and second fixing members can achieve high-precision opening and closing.

[0060] The first direction X, the second direction Y, and the third direction Z intersect each other. For example, the first direction X can be... Figure 2 and Figure 3 The vertical direction in the middle, the second direction Y can be Figure 2 and Figure 3 In the horizontal direction, the third direction Z can be Figure 2 and Figure 3 The front and back directions in the middle.

[0061] In one specific embodiment, the base 11 includes a fixing part 111 and a connecting part 112. The fixing part 111 has a positioning surface and a mounting surface distributed along a first direction X. The mounting surface is fixedly connected to the connecting part 112, and the interior of the connecting part 112 encloses a rotating cavity. The positioning surface can be a plane, an inclined plane, a trapezoidal cross section, a triangular cross section, etc. The positioning surface of the fixing part 111 is adapted to the assembly surface of the hydraulic support 2 so that the positioning surface of the fixing part 111 is fully adapted to the assembly surface of the hydraulic support 2. Then, the base 11 is fixed to the structural component of the hydraulic support 2 with bolts to improve the stability and reliability of the installation.

[0062] The installation process of the portable hydraulic support hose protection device in this embodiment is as follows: First, fix the protection device on the structural component of the hydraulic support 2; second, place the hydraulic hose on the elastic sleeve 133; finally, tighten all fixing parts.

[0063] In this design, when the hydraulic support 2 operates, the hydraulic hose moves via the elastic sleeve 133. The rotating body 121 and the rotating cavity inside the device form a rotating pair, allowing the elastic sleeve 133 to rotate and oscillate in multiple dimensions according to the position of the hydraulic hose. This enables the hydraulic hose to adapt to complex installation and usage environments, providing high flexibility to suit different working conditions. Furthermore, the elastic sleeve 133 absorbs minor displacements and vibrations of the hydraulic hose and ensures that the hydraulic hose does not directly contact the hydraulic support, protecting the hydraulic hose from damage.

[0064] This device effectively wraps the hose by using a rubber pad and utilizes a ball joint to provide multi-directional rotational capability, creating a certain degree of isolation between the hose and the hydraulic support structure 2. This reduces the chance of friction and contact, thereby reducing wear. Furthermore, the elasticity of the rubber pad absorbs minor vibrations and swaying, further minimizing damage to the hose.

[0065] In this embodiment, the combined structure of the first fixing member, the second fixing member, and the elastic sleeve 133 ensures that the hose is adequately cushioned when subjected to slight swaying and vibration. The flexible rotation of the spherical universal joint further expands the adaptability of the device, allowing the hose to bend and swing unrestricted, thereby protecting the hydraulic hose.

[0066] In summary, the embodiments of this application provide a convenient hydraulic support hose protection device, which significantly improves the service life of hydraulic hoses, reduces equipment failures and safety accidents caused by hose wear, and lowers maintenance costs.

[0067] The above provides a detailed description of the portable hydraulic support hose protection device provided in this application. Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are merely for the purpose of helping to understand the method and core ideas of this application. It should be noted that those skilled in the art can make various improvements and modifications to this application without departing from its principles, and these improvements and modifications also fall within the protection scope of this application.
