Description

Technical Field

[0001] This invention relates to the field of hydraulic support technology, and in particular to a method for installing a connecting device in a hydraulic support. Background Technology

[0002] As the core support equipment in fully mechanized coal mining faces, the operational stability of the hydraulic system of hydraulic supports directly determines the accuracy of support actions and the safety of coal mining operations. Within the hydraulic system, various hydraulic components are connected via oil pipe joints to achieve hydraulic circuit connectivity. The coaxiality deviation of the oil circuit interfaces must be strictly controlled within the allowable range to avoid problems such as hydraulic oil leakage or pressure loss, thereby ensuring the responsiveness and operational reliability of the hydraulic system.

[0003] In existing technologies, operators typically use manual marking to position the oil pipe joints of various hydraulic components, and then assemble the oil pipe joints sequentially. However, this method is highly dependent on the operator's personal experience, and with different components being marked and assembled independently, errors at each stage can easily accumulate, making it difficult for the coaxiality of the oil pipe joints to meet design requirements, thus affecting the overall stability and support performance of the hydraulic support. To overcome the shortcomings of the above-mentioned marking and assembly method, connecting devices can be installed between hydraulic components to achieve accurate positioning of the oil pipe joints. However, the installation accuracy of the connecting device itself directly determines the final connection quality of the oil pipe joints.

[0004] Therefore, there is an urgent need for a method to improve the installation accuracy of connecting devices in order to enhance the reliability of oil pipe joint connections. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides an installation method for the connecting device in a hydraulic support, which solves the technical problem of poor reliability of oil pipe joint connection caused by insufficient installation accuracy of the connecting device in the prior art.

[0039] To better explain and facilitate understanding of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0040] This invention provides a method for installing the connecting device 1 in a hydraulic support, using the following method:

[0041] S1, such as Figure 5 As shown, a connecting device 1 is provided, which includes a fixing plate 11, a bending plate 12, and a bearing seat 13 connected in sequence, as shown. Figure 4 As shown, a positioning and receiving space is formed between the bending plate 12 and the fixing plate 11, which can accommodate the multi-way valve 3 in the oil pipe joint, and the bearing seat 13 can provide positioning support for the backwash filter 4 in the oil pipe joint.

[0042] S2. The first tooling 5 is used to detachably connect the fixing plate 11 to the front wall 21 of the base 2 in the hydraulic support;

[0043] S3. The second tooling 6 is used to detachably connect the bearing seat 13 between the two side walls 22 of the base 2 in the hydraulic support.

[0044] In step S1, as Figure 7 As shown, the bending plate 12 includes a horizontal part 121 and a vertical part 122 connected together. The horizontal part 121 is located at the bottom end of the vertical part 122. The fixing plate 11 is connected to the horizontal part 121, and the bearing seat 13 is connected to the vertical part 122.

[0045] like Figure 5 and Figure 6 As shown, the top of the fixing plate 11 protrudes beyond the horizontal portion 121 of the bending plate 12 to form a positioning and receiving space together with the bending plate 12. This positioning and receiving space has an upward-opening "U" shape, and its width matches the outer dimensions of the multi-way valve 3. The protruding portion at the top of the fixing plate 11 serves as a side limiting stop for the multi-way valve 3, preventing lateral movement of the multi-way valve 3 under hydraulic pulsation or bracket vibration. Simultaneously, this protruding structure serves as a visual positioning reference during assembly. The operator only needs to press the side of the multi-way valve 3 tightly against the inner side of the protruding portion at the top of the fixing plate 11 to quickly position the multi-way valve 3 in the horizontal direction, further improving assembly efficiency.

[0046] like Figure 6 As shown, to improve the structural rigidity at the connection between the fixed plate 11 and the bent plate 12, the connecting device 1 also includes a reinforcing plate 14. The reinforcing plate 14 is arranged vertically, attached to the fixed plate 11, and its top end is connected to the horizontal part 121. The bearing seat 13 is provided with two connecting columns, which are spaced apart at the bottom end of the support plate 131. The two connecting columns are respectively connected to the two side walls 22 of the base 2 in the hydraulic support.

[0047] like Figure 6 As shown, the support base 13 also includes a connecting block 133, which has an inverted concave structure. The top of the connecting block 133 is connected to the support plate 131, and the two legs of the connecting block 133 are respectively connected to two connecting columns.

[0048] Before the connecting device 1 is installed onto the base 2 of the hydraulic support, the support plate 131, connecting block 133, and guide column 132 in the bearing seat 13 are welded together. The fixing plate 11 in the connecting device 1 is pre-welded and fixed to the horizontal part 121, and the support plate 131 in the bearing seat 13 is pre-welded and fixed to the vertical part 122 of the bent plate 12. The reinforcing plate 14 is arranged vertically, welded to the fixing plate 11, and the top end of the reinforcing plate 14 is welded and fixed to the horizontal part 121.

[0049] Preferably, both the fixing plate 11 and the support plate 131 provided in step S1 are provided with positioning holes, so that when the oil pipe joint is installed, the positioning holes match and are positioned with the corresponding structures on the oil pipe joint.

[0050] like Figure 2As shown, the first tooling 5 used in step S2 includes a base plate 51. The base plate 51 has a mounting groove in the vertical direction. During installation, the fixing plate 11 is first placed in the mounting groove, and the fixing plate 11 is connected to the front wall 21 of the base 2 in the hydraulic support through the base plate 51, so that the top of the fixing plate 11 protrudes from the base plate 51. The protruding part and the bending plate 12 together form a positioning and receiving space. Then, the base plate 51 and the fixing plate 11 are detachably connected. The inner wall of the mounting groove forms a horizontal constraint on the fixing plate 11, avoiding the problem of the fixing plate 11 tilting due to manual drawing deviation or visual misalignment in the traditional scribing method. In order to facilitate the positioning of the base plate 51, the first tooling 5 used in step S2 also includes positioning protrusions 52 provided on both sides of the base plate 51. During installation, the positioning protrusions 52 are matched and positioned with the positioning holes on the front wall 21 of the base 2 in the hydraulic support, and then the fixing plate 11 is fixed to the front wall 21 of the base 2 in the hydraulic support. The positioning protrusion 52 and the existing positioning hole on the front wall 21 of the base 2 are fitted with a precision fitting method with a gap of no more than 0.2mm, which realizes the rapid and slip-free positioning of the substrate 51 on the front wall 21 of the base 2 and eliminates the cumulative error caused by inconsistent positioning reference.

[0051] like Figure 3 As shown, in step S3, the guide post 132 is detachably connected to the two side walls 22 of the base 2 in the hydraulic support via the second tooling 6. Wherein, as... Figure 3 The second tooling 6 used in step S3 includes two fixing units, which correspond one-to-one with the guide posts 132. During installation, one side of each fixing unit is first connected and fixed to the side wall 22 of the base 2 in the hydraulic support. A longitudinally extending channel is opened on the other side of the fixing unit, and the guide posts 132 are then inserted into the channel, making the guide posts 132 detachably connected to the channel. The fixing unit used in step S3 includes a fixing sleeve 61 and a connecting seat 62. During installation, the fixing sleeve 61 is first connected to the side wall 22 of the base 2 in the hydraulic support, and then one end of the connecting seat 62 is inserted into the fixing sleeve 61, with the other end of the connecting seat 62 forming a channel. The fixing sleeve 61 serves as a reference component pre-precisely installed on the side wall 22; it can be directly mounted on the reinforcing plate of the side wall 22 of the base 2 and calibrated using a special measuring tool.

[0052] The connecting seat 62 used in step S3 includes a cylindrical part 621, a connecting part 622, and a cylindrical part 623. The cylindrical part 621 is integrally connected to the cylindrical part 623 through the connecting part 622, and a channel is formed inside the cylindrical part 623. During installation, the cylindrical part 621 is inserted into the fixing sleeve 61, and then the guide post 132 is inserted into the cylindrical part 623. The height of the support plate 131 is adjusted by the sliding fit between the guide post 132 and the cylindrical part 623. This sliding fit structure can be flexibly adjusted according to the actual installation height requirements of the oil pipe joint. At the same time, by setting the sleeve-post fit between the cylindrical part 623 and the guide post 132, and between the cylindrical part 621 and the fixing sleeve 61, the installation of the guide post 132 is facilitated, effectively avoiding assembly difficulties caused by production errors. After the height is adjusted to the correct position, it is locked and fixed. Finally, the cylindrical part 621 and the fixing sleeve 61 are locked and fixed.

[0053] The installation method of the connecting device 1 in the hydraulic support, by providing a connecting device 1 with positioning and accommodating space and positioning support functions, enables rapid positioning and installation of the multi-way valve 3 and the backwash filter 4. The entire process requires no manual marking, avoiding installation deviations caused by reliance on operator experience and accumulated errors from multiple stages in traditional assembly methods. Simultaneously, by using the first tooling 5 and the second tooling 6 respectively to install the connecting device 1 between the front wall 21 and the two side walls 22 of the hydraulic support base 2, the installation accuracy of the connecting device 1 itself is effectively guaranteed. This ensures high coaxiality when the oil pipe joints are connected to the pipeline, reduces the risk of hydraulic oil leakage and pressure loss, and improves assembly efficiency and the operational reliability of the hydraulic system.
