Description

Technical Field

[0001] This utility model belongs to the technical field of downhole directional valve installation equipment, specifically an adjustable support frame for directional valve installation. Background Technology

[0002] Coal miners use underground hydraulic supports by operating directional valves to control their movement. The safe and reliable installation of these directional valves is paramount in hydraulic support design. Because the mining height varies at different stages of a fully mechanized mining face, hydraulic supports may require different support heights. Adjustable installation height of the directional valves has become a growing demand from customers when accepting hydraulic supports. If the installation height of the directional valves can be adjusted, transport hydraulic supports can be installed without disassembling the valves in some mines with demanding transport roadways, reducing the workload of mine installation.

[0003] Due to downhole operating practices, directional valves are typically installed in the middle of the hydraulic support base. However, the presence of other structural components and hydraulic columns in this vicinity, coupled with the relatively large size of the directional valve and the limited assembly space, makes installation and maintenance challenging. Therefore, finding a simple, low-cost, and reliably height-adjustable directional valve mounting bracket has become an urgent problem to solve. Summary of the Invention

[0004] In order to solve the above problems, the present invention provides an adjustable support frame for mounting a reversing valve.

[0005] The present invention adopts the following technical solution: an adjustable support frame for mounting a reversing valve, comprising:

[0006] A fixed base is fixedly connected to the hydraulic support base.

[0007] The height adjustment mechanism includes two vertical adjustment plates with elongated holes extending in the vertical direction;

[0008] The valve body connection assembly includes a connection plate for fixing the directional valve, which is movably connected to the height adjustment mechanism by fastening bolts;

[0009] The fastening bolt can slide along the elongated hole and be selectively fixed, enabling continuous or stepped adjustment of the reversing valve installation height, without the need to completely disassemble the fastening bolt during the height adjustment process.

[0010] In some embodiments, at least two fixing slots are provided on one side of the elongated hole, and the height can be adjusted in different increments by inserting the fastening bolts into different fixing slots.

[0011] In some embodiments, mounting holes are provided on both sides of the connecting plate, and the relative positions of the mounting holes and the elongated holes are determined to ensure assembly accuracy.

[0012] In some embodiments, the vertical adjustment plate is formed by one-time bending of low-alloy high-strength steel, and the elongated hole is formed by laser cutting.

[0013] In some embodiments, the lowest adjustment position of the support frame ensures that the directional valve remains uninterrupted even when the hydraulic support is lowered to its lowest height, making it suitable for narrow transport lanes.

[0014] In some embodiments, the vertical adjustment plate is welded to the fixed base.

[0015] In some embodiments, the surface of the connecting plate is provided with a plurality of circular holes for mounting and connecting the directional valve.

[0016] In some embodiments, the height of the support frame is adjustable from 0 to 240 mm to accommodate standing operation postures and reduce bending fatigue.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This utility model provides an adjustable support frame for installing a directional valve. Through the coordinated design of the adjustment elongated hole and bolt fixing slot on the vertically fixed valve plate, it achieves three-level height adjustment of the directional valve within the range of 0-240mm without disassembly. Workers only need to tighten or loosen the nut to slide the bolt and complete the height adjustment, completely solving the problem of repeatedly disassembling and reassembling the directional valve due to changes in underground mining height. This reduces adjustment operation time by more than 60%, significantly reducing labor intensity and safety risks.

[0019] The support frame is made of low-alloy high-strength steel through laser cutting and one-time bending forming process, which ensures the structural strength of the valve plate. At the same time, it achieves millimeter-level assembly accuracy by precisely matching the size relationship between the directional valve mounting hole and the long strip hole of the valve plate, thus avoiding valve body failure due to processing errors.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] like Figure 1-4 As shown, an adjustable support bracket for mounting a directional control valve includes:

[0027] Fixed base 3 is fixedly connected to the hydraulic support base;

[0028] The height adjustment mechanism includes two vertical adjustment plates 1 with elongated holes 11 extending in the vertical direction;

[0029] The valve body connection assembly includes a connecting plate 2 for fixing the directional valve, which is movably connected to the height adjustment mechanism by fastening bolts;

[0030] The fastening bolt can slide along the elongated hole and be selectively fixed, enabling continuous or stepped adjustment of the reversing valve installation height, without the need to completely disassemble the fastening bolt during the height adjustment process.

[0031] Specifically, the fixed base 3 is made of Q345B low-alloy high-strength steel plate (12mm thick), and is symmetrically welded to both sides of the middle section of the hydraulic support base through continuous fillet welds. The welding position strictly avoids the hydraulic column and adjacent structural components (such as the jack lugs) to ensure that the strength of the base is not weakened.

[0032] The vertical adjustment plate 1 is made of two 8mm thick Q345B steel plates, which are laser-cut into elongated holes 11 and three equidistant fixed slots 12, and then formed by a one-time bending process. The elongated holes are 240mm long, and the slot spacing is 80mm, corresponding to three adjustment levels of 80mm, 160mm, and 240mm.

[0033] The elongated hole 11 has at least two fixing slots 12 on one side, and the height can be adjusted in different increments by inserting the fastening bolts into the different fixing slots 12.

[0034] Mounting holes are provided on both sides of the connecting plate 2. The relative positions of the mounting holes 22 and the elongated holes 11 are determined to ensure assembly accuracy.

[0035] The vertical adjustment plate 1 is formed by bending low-alloy high-strength steel in one step, and the elongated hole 11 is formed by laser cutting.

[0036] The lowest adjustment setting of the support frame ensures that the directional valve remains uninterrupted even when the hydraulic support is lowered to its lowest height, making it suitable for narrow transport lanes.

[0037] The vertical adjustment plate 1 is welded to the fixed base 3.

[0038] Multiple round holes 21 are provided on the surface of the connecting plate 2 for installing and connecting the directional valve.

[0039] The height of the support frame is adjustable from 0 to 240 mm, which is suitable for standing operation and reduces bending fatigue.

[0040] Assembly and adjustment process

[0041] Step 1: Place the reversing valve on the connecting plate 2 and fix the valve body using 8 sets of M10 high-strength bolts through the round hole 21;

[0042] Step 2: Attach the connecting plate 2 to the vertical adjustment plate 1, align the adapter hole 22 with the elongated hole 11, and insert the M16 adjusting bolt;

[0043] Step 3: After loosening the nut, slide the connecting plate 2, insert the bolt into the target slot 12 as needed, and tighten the self-locking nut to complete the height locking.

[0044] The purpose of this invention is to provide a safe and reliable structure for adjusting the height of a directional valve, with an adjustment range of 0-240mm to meet various operating environments in coal mining faces. Adjusting the height is simple, requiring only the removal and installation of bolts, even in confined spaces, and can be completed without completely removing the bolts, reducing the difficulty of directional valve assembly and maintenance. After adjustment, the bolts are placed in the fixed slots of the valve plate, ensuring both safe and reliable height adjustment and structural strength of the fixed directional valve. In mines with demanding transport roadways, even when the hydraulic support height is at its lowest setting, the directional valve height adjustment will not cause interference, ensuring that the directional valve is not frequently disassembled during transport and relocation, reducing the workload of mine workers and extending the service life of the hydraulic support. After the hydraulic support is installed and arranged in the coal mining face, the support frame height can be adjusted, eliminating the need for workers to bend over when operating the directional valve. The design fully considers ergonomics, reducing the possibility of worker misoperation and increasing equipment safety.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
