[0036] In coal mining, hydraulic supports are important support equipment used to support and protect the working surface in the mine. Hydraulic supports contain hydraulic hoses, which are used to transmit hydraulic oil and other working media. However, due to the frequent movement of the equipment, the hydraulic hoses often come into direct contact with the structural components of the support, causing the hoses to wear and even damage. This is mainly manifested by scratches and squeezing of the hydraulic hoses. This not only affects the normal operation of the hydraulic system and reduces production efficiency, but can also cause equipment failure or safety accidents, increase maintenance costs, and pose safety hazards related to safety accidents. Existing protective measures cannot effectively prevent direct contact between hoses and structural components, resulting in accelerated wear of these parts due to friction, squeezing, etc.

[0037] In view of this, the present application provides a convenient hydraulic support hose protection device, which not only effectively protects the hydraulic hose, but also provides multi-dimensional, flexible rotation and adjustment capabilities to ensure that the hose can work flexibly and smoothly in different environments, solve the problem of hydraulic hose wear and damage caused by direct contact between the hose and the hydraulic support structural parts, and extend 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 a portable hydraulic support hose protection device in an assembled state provided in some embodiments of the present application; Figure 2 This is a schematic structural diagram of the portable hydraulic support hose protection device provided in some embodiments of the present application when it is in working state.

[0039] The present application provides a portable hydraulic support hose protection device, comprising at least one protection body 1, the protection body 1 comprising: a base 11, an angle adjustment member 12, and a hose fixing assembly 13, wherein the base 11 is fixedly connected to the hydraulic support 2, the base 11 encloses a rotation cavity, at least a portion of the angle adjustment member 12 is embedded in the rotation cavity, and the angle adjustment member 12 is used to rotate and connect to the rotation cavity, thereby adjusting the installation position and installation angle of the hydraulic hose relative to the hydraulic support 2. The hose fixing assembly 13 is arranged on the side of the angle adjustment member 12 facing away from the base 11, and the hose fixing assembly 13 includes at least two fixing members 131 and a locking portion 132. Each fixing member 131 encloses a fixing cavity, which can circumferentially fix the hose, and the locking portion 132 is used to lock each fixing member 131.

[0040] The base 11 is used to fix the entire device on the structural member of the hydraulic support 2. The hose fixing assembly 13 and each fixing member 131 can facilitate the placement of the hose when opened. When closed, each fixing member 131 cooperates to wrap the hydraulic hose and fix the position through the locking member.

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

[0042] When fixing the hydraulic hose, the fixing cavity of the fixing member 131 is opened, the hydraulic hose is placed in the fixing cavity, and finally the fixing members 131 are locked by the locking portion 132 to fix the hydraulic hose.

[0043] The portable hydraulic support hose protection device provided in this application installs a protection device between the hydraulic hose and the hydraulic support 2 structural member, uses the hose fixing assembly 13 to effectively wrap the hydraulic hose, reduces the wear of the hydraulic hose, and uses the angle adjustment member 12 to provide multi-dimensional, flexible rotation and adjustment capabilities to ensure that the hose can work smoothly in different environments, thereby achieving the protection purpose.

[0044] In a specific embodiment, the angle adjustment member 12 includes a rotating body 121 and a connecting rod 122, the connecting rod 122 is fixedly connected to the side of the rotating body 121 facing away from the base 11, at least part of the rotating body 121 is rotatably connected to the rotating cavity, and the two ends of the connecting member along the first direction X are respectively fixedly connected to the rotating body 121 and the hose fixing assembly 13.

[0045] The rotating body 121 can be Figure 1 The sphere, hemisphere, elliptical sphere, etc. in the figure, correspondingly, the rotating cavity is a spherical cavity, a hemispherical cavity, an elliptical spherical cavity, etc., and the rotating body 121 is rotatably connected to the rotating cavity.

[0046] The connecting rod 122 plays a supporting role and is connected 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, so that the device can adapt to different working conditions. The ball universal joint seat is fixed to the base 11 to support the ball universal joint.

[0047] The connecting rod 122 can be a cylindrical rod, a square rod or a frame structure, one end of which 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 to adjust the position and angle of the hose fixing assembly 13.

[0048] Therefore, by rotating the hose fixing assembly 13 and / or the angle adjustment member 12, the angle adjustment 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 a specific embodiment, the hose fixing assembly 13 includes at least two fixing members 131 distributed along the circumference. The fixing members 131 are provided with locking structures and inner cavities. All the locking structures cooperate and position so that all the inner cavities form a fixed cavity.

[0050] The fixing members 131 can be half, one-third, or one-quarter the size. All the fixing members 131 are assembled circumferentially to form the hose fixing assembly 13. The inner cavity of the fixing members 131 can be a semicircular or fan-shaped structure. The inner cavities of all the fixing members 131 cooperate to form a fixed cavity. The various locking structures cooperate and position so that all the inner cavities form a fixed cavity, thereby forming a structure for circumferentially fixing the hydraulic hose. This protects the local structure of the outer circumference of the hydraulic cavity tube.

[0051] like Figure 2 and Figure 3 As shown, the hose fixing assembly 13 includes a first fixing member and a second fixing member. The two fixing members 131 are distributed along the first direction X. The first fixing member has a first inner cavity inside, and a first locking structure is provided on the outer wall of the first fixing member. The second fixing member has a second inner cavity inside, and a second locking structure is provided on the outer wall of the second fixing member. The first locking structure cooperates with the second locking structure to form a fixed cavity, which wraps the hydraulic hose. The first locking structure and the second locking structure are then locked and fixed using the locking member 134.

[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 defined therein, and a first locking structure defined on its outer wall. The second fixing member has a second inner cavity defined therein, and a second locking structure defined on its outer wall. The first locking structure cooperates with the second locking structure to form a fixing cavity for fixing the hydraulic hose. The first and second fixing members can be opened to facilitate 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, and the second direction Y intersects with the first direction X.

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

[0055] When installing the hydraulic hose, open the first fixing member and the second fixing member, place the hydraulic hose in the first inner cavity and the second inner cavity, cover the first fixing member and the second fixing member, and use a locking member 134 such as a bolt to tighten one side of the first fixing member and the second fixing member to complete the fixing of the hydraulic hose.

[0056] Furthermore, in order to achieve effective protection of the hydraulic hose, the fixing part 131 can also be provided with at least two elastic sleeves 133, and the elastic sleeves 133 are fixedly connected to the inner cavity of each fixing part 131. The elastic sleeves 133 can be elastic sleeves, such as rubber sleeves, silicone sleeves, etc., which can be adhesively fixed to the inner wall of the fixing part 131. The elastic sleeves 133 are used to wrap the hydraulic hose to provide buffering force and reduce wear. In combination with the circumferentially distributed elastic sleeves 133, the hydraulic hose can be wrapped in all directions along the circumference to avoid 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, elastic sleeve 133 forms elastic contact with the hydraulic hose, absorbing vibration and friction generated during hydraulic equipment operation, thereby preventing frictional damage to the hydraulic hose. Furthermore, the spherical universal joint formed by rotor 121 and the rotating chamber allows for multiple angle adjustments to accommodate varying operating 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 connecting ends of the two fixing members 131. Specifically, the first connecting end of the first fixing member is provided with a plurality of limiting blocks 136 distributed along the third direction Z, with each limiting block 136 spaced apart. The second connecting end of the second fixing member is provided with a plurality of limiting grooves 135 spaced apart, with the limiting blocks 136 rotatably connected to the limiting grooves 135. The hose fixing assembly 13 also includes a rotating shaft 137, which is provided on the base 11 along the third direction Z and is provided 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 fixing member and the second fixing member rotate around the rotating shaft 137, the limiting block 136 can be limited by the limiting groove 135 to improve the movement accuracy between the first fixing member and the second fixing member, ensuring that the first fixing member and the second fixing member can be opened and closed with high precision.

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

[0061] In a specific embodiment, the base 11 includes a fixing portion 111 and a connecting portion 112. The fixing portion 111 is provided with a positioning surface and a mounting surface distributed along a first direction X. The mounting surface is fixedly connected to the connecting portion 112, and the interior of the connecting portion 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 portion 111 is adapted to the assembly surface of the hydraulic support 2. To ensure that the positioning surface of the fixing portion 111 and the assembly surface of the hydraulic support 2 are fully adapted, the base 11 is then fixed to the structural components 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 the embodiment of the present application is as follows: first, fix the protection device on the structural member of the hydraulic support 2; second, place the hydraulic hose on the elastic sleeve 133; finally, tighten each fixing part.

[0063] In this solution, when the hydraulic support 2 is in motion, the hydraulic hose moves via the elastic sleeve 133. The rotating element 121 and the rotating chamber within the device form a revolute pair, allowing the elastic sleeve 133 to rotate and swing in multiple dimensions according to the position of the hydraulic hose. This allows the hydraulic hose to adapt to complex installation and use environments, providing high flexibility to accommodate diverse operating conditions. Furthermore, the elastic sleeve 133 absorbs minor displacements and vibrations of the hydraulic hose and ensures that the hydraulic hose does not come into direct contact with the hydraulic support, protecting the hydraulic hose from damage.

[0064] This device effectively wraps the hose with a rubber pad and utilizes a ball joint to provide multi-directional rotation. This creates a certain degree of isolation between the hose and the hydraulic support 2 structural components, reducing friction and contact, thereby reducing wear. Furthermore, the elasticity of the rubber pad absorbs minor vibrations and sway, further minimizing damage to the hose.

[0065] In this embodiment, the combined structure of the first and second fixing members and the elastic sleeve 133 ensures that the hose is adequately cushioned against slight sway and vibration. The flexible rotation of the ball joint further expands the adaptability of the device, allowing the hose to bend and swing without constraint, thereby protecting the hydraulic hose.

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

[0067] The above is a detailed introduction to the portable hydraulic support hose protection device provided by this application. This article uses specific examples to illustrate the principles and implementation methods of this application. The description of the above examples is only intended to help understand the method and core concept of this application. It should be noted that for ordinary technicians in this technical field, various improvements and modifications can be made to this application without departing from the principles of this application, and these improvements and modifications also fall within the scope of protection of this application.
