Description

Technical Field

[0001] This utility model belongs to the field of hydraulic support technology, and in particular relates to a tooling for ensuring the deflection angle of the U-shaped lug of a hydraulic support. Background Technology

[0002] A diagram illustrating the angle deflection of the U-shaped earpiece is shown below. Figure 1 As shown. In this diagram, number A represents the main rib of the base, and number B represents the U-shaped lug. The U-shaped lug is deflected at a certain angle α relative to the vertical direction. Currently, riveting assemblies primarily rely on alignment with scribing lines or the use of templates with fixed angles to ensure this deflection angle.

[0003] Combination Figure 1 Currently, there are two main methods for assembling U-shaped lugs: (1) riveting and marking; (2) assembly using templates with fixed angles. However, due to the obstruction of the mounting plate near the U-shaped lug, the actual efficiency of marking and assembly is low, and the marking accuracy cannot be guaranteed.

[0004] If a fixed-angle template is used for assembly, the template's applicability is poor. When the deflection angle of the U-shaped lug changes, a template with a new angle needs to be made. Utility Model Content

[0045] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0046] Example 1

[0047] like Figure 2 and Figure 3 As shown: This embodiment discloses a tooling for ensuring the deflection angle of the U-shaped lug of the hydraulic support, including: dial 1, pointer 6 and fixing component.

[0048] The dial 1 can be detachably fixed on the main rib of the base of the U-shaped ear to be installed with the help of the fixing member; the dial 1 is provided with an angle sticker 2; the pointer 6 is set on the dial 1 and can position and fix the deflection angle to help limit the deflection angle of the U-shaped ear.

[0049] In this embodiment, the dial 1 is placed on the main rib of the base of the U-shaped ear seat and kept horizontal relative to the ground.

[0050] The dial 1 includes an upper semicircular ring and a lower support strip; the upper semicircular ring and the lower support strip are integrally formed; the upper semicircular ring is provided with the angle sticker 2; the angle sticker 2 is provided with a scale and numerical value of 0-180°.

[0051] Specifically, the lower support bar has first mounting holes at both ends; a second mounting hole is provided in the middle of the lower support bar; the two first mounting holes can accommodate the fixing member; and the second mounting hole can accommodate the pointer 6.

[0052] The fastener includes two round steel bars 5; the two round steel bars 5 are spot-welded and fixed in the first mounting hole; the two round steel bars 5 can overlap on the main rib of the base of the U-shaped ear seat to be installed, and fix the dial 1 in a horizontal position.

[0053] In this embodiment, the pointer 6 is provided with a connecting hole; the second mounting hole is provided with a bolt 3; the bolt 3 can pass through the connecting hole; the pointer 6 can be fixedly mounted on the lower support bar with adjustable angle by means of the bolt 3 and nut 4, and the needle of the pointer 6 can point to the angle sticker 2 on the upper semi-circular part to determine the deflection angle of the pointer 6.

[0054] In this embodiment, the length of the tail of the pointer 6 is sufficient to reach the installation position of the U-shaped earpiece. During installation, the U-shaped earpiece can rotate until its right end face contacts the tail of the pointer 6, ensuring the deflection angle during installation. The surface of the pointer 6 is coated with a fluorescent coating; the tip of the pointer 6 is inlaid with red highly reflective material; a reinforcing rib is provided in the middle of the pointer 6; the reinforcing rib is cross-shaped and integrally formed with the pointer. The pointer 6 is coated with a fluorescent coating, and a red highly reflective material is inlaid at its tip. Simultaneously, by increasing the moment of inertia of the pointer 6, its bending resistance is improved, preventing the pointer 6 from bending and deforming due to external impacts or compression during use, thus affecting the accuracy of angle indication.

[0055] The connection between the round steel 5 and the dial 1 is provided with a dovetail groove structure; the end of the round steel 5 has a dovetail shape that matches the dovetail groove structure.

[0056] In this embodiment, the end of the round steel 5 is machined into a dovetail shape that matches the dovetail groove. After the round steel 5 is embedded into the dovetail groove, it is spot welded using inert gas shielded welding. Compared with simple spot welding, this connection method can restrict the displacement of the round steel 5 in multiple directions, making the connection between the round steel 5 and the dial 1 more firm and stable, and preventing the round steel 5 from loosening or falling off during the use of the tooling.

[0057] In this embodiment, before using the fixture, the operator first needs to adjust the fixture pointer 6 to the corresponding angle using the bolts 3 of the fixture, according to the U-shaped lug deflection angle marked on the drawing. After adjustment, tighten the nut 4, at which point the pointer 6 can be firmly fixed.

[0058] When the two Φ10 round steel bars 5 of the fixture are overlapped on the main rib of the base, a high-precision bubble level placed on the edge of the dial 1 can be used to ensure that the fixture is level. If it is not level, shims of different thicknesses can be added between the round steel bars 5 and the main rib to adjust and ensure that the fixture is placed horizontally.

[0059] Example 2

[0060] In complex working conditions such as underground coal mines, hydraulic supports are key equipment for ensuring safe production, and the installation accuracy of their U-shaped lugs directly affects the overall performance and stability of the supports. For example... Figure 2 and Figure 3 As shown, the tooling provided in this embodiment for ensuring the deflection angle of the U-shaped lug of the hydraulic support is designed with high precision, ease of operation and strong stability as its design goals. Through the coordinated work of the dial 1, pointer 6 and the fixing parts, it provides a reliable angle reference for the installation of the U-shaped lug.

[0061] As the core carrier of the tooling, dial 1 can be detachably fixed to the main rib of the base of the U-shaped lug to be installed using fasteners. Dial 1 is made of ordinary carbon steel, which has the characteristics of high strength, low cost, easy availability and easy processing, and can effectively cope with the harsh environment of dusty assembly workshops.

[0062] The unique structure of dial 1 consists of an upper semi-circular section and a lower support strip, both manufactured using a one-piece molding process. This design significantly enhances the overall strength and rigidity of dial 1, avoiding stress concentration and potential breakage risks caused by structural splicing. The upper semi-circular section serves as the angle display area, with angle sticker 2 tightly attached to it. Angle sticker 2 is precisely drawn using professional CAD software to ensure the accuracy and uniformity of the scale, covering a range of 0-180°, with corresponding values ​​clearly marked. To guarantee the clarity and durability of angle sticker 2 during long-term use, it is manufactured using high-precision UV printing technology. After printing, a transparent, scratch-resistant, and wear-resistant coating is applied. This coating possesses excellent optical transparency and UV resistance, ensuring the scale remains clearly legible even under strong light or frequent friction.

[0063] The lower support bar, as a key component connecting and fixing the pointer, has first mounting holes at both ends and a second mounting hole in the middle. The first mounting holes are used to install the fixing component, while the second mounting hole is responsible for installing the pointer 6. The fixing component consists of two round steel bars 5, which are made of high-quality Q235 carbon structural steel and have undergone heat treatment to achieve excellent comprehensive mechanical properties, with strength and toughness achieving an optimal balance. The two round steel bars 5 are securely connected to the first mounting holes through a unique dovetail groove structure. A dovetail shape matching the dovetail groove is machined at the end of the round steel bar 5. After the round steel bar 5 is embedded into the dovetail groove, it is spot welded using inert gas shielded welding. This connection method not only restricts the displacement of the round steel bar 5 in multiple directions but also fully utilizes the high strength characteristics of welding, making the connection between the round steel bar 5 and the dial 1 firm and reliable, capable of withstanding large external forces without loosening or falling off. Meanwhile, after installation, the two round steel bars 5 can overlap on the main rib of the base of the U-shaped ear seat to be installed. Through reasonable length design and structural layout, the dial 1 is kept in a horizontal position, laying the foundation for accurate angle measurement.

[0064] The pointer 6, as a key component indicating the angle, also employs a special design. Its main body is made of carbon structural steel, possessing excellent machinability and strength. The pointer 6 has a connecting hole that mates with the bolt 3 on the second mounting hole to achieve a fixed adjustable angle. To improve the adjustment accuracy and stability of the pointer 6, an anti-loosening washer is added between the bolt 3 and the nut 4. Through its unique elastic structure, the anti-loosening washer generates a continuous preload after the nut is tightened, effectively preventing the nut from loosening under vibration and ensuring that the pointer 6 always remains at the set angle.

[0065] Furthermore, the design of pointer 6 fully considers ease of use and durability. Its surface is coated with a special fluorescent coating that absorbs light energy in bright light and automatically glows in low-light downhole environments, ensuring operators can clearly observe the pointer's position under any lighting conditions. A red, highly reflective material is inlaid at the tip of pointer 6 to further enhance visual indication. A cross-shaped reinforcing rib is integrated into the center of pointer 6, significantly improving its bending resistance by increasing the pointer's moment of inertia. Even under external impact or compression, it effectively maintains its shape stability, preventing deformation from affecting the accuracy of angle indication. Simultaneously, the tail of pointer 6 is precisely calculated and designed to accommodate the U-shaped lug. During installation, when the U-shaped lug rotates to contact the tail of pointer 6 with its right end face, the deflection angle of the U-shaped lug is accurately guaranteed.

[0066] To further improve the performance and ease of operation of the tooling, several key functional structures of the tooling have been deeply optimized and innovatively designed.

[0067] In actual use, operators must strictly follow the standard procedures when using the tooling to ensure the accuracy of the U-shaped lug deflection angle and the installation quality.

[0068] Before using the fixture, the operator must first adjust the fixture pointer 6 to the corresponding angle according to the U-shaped lug deflection angle marked on the drawing. Specifically, loosen the nut 4 first, then slowly rotate the pointer 6. By observing the position of the angle sticker 2 on the dial 1 and the pointer 6, adjust the pointer 6 to the desired angle. After adjustment, ensure the pointer 6 is fixed in position. Next, tighten the nut 4. Due to the synergistic effect of the micro-locking washers, the pointer 6 will be firmly fixed at the set angle.

[0069] When attaching the two round steel bars 5 of the tooling to the main rib of the base, the operator should first observe the bubble level on the edge of the dial 1 to ensure that the tooling is level. If it is not level, it can be adjusted by adding shims of different thicknesses between the round steel bars 5 and the main rib. The shims adopt a stepped design and come in several different thicknesses, which the operator can quickly combine and use according to actual needs to achieve precise leveling of the tooling.

[0070] When installing the U-shaped lug, slowly rotate it so that its right end face gradually approaches the tail of pointer 6. During this approach, the operator must closely observe the contact between the U-shaped lug and pointer 6. When the right end face of the U-shaped lug is in complete contact with pointer 6, it indicates that the U-shaped lug has reached the set deflection angle. At this point, the U-shaped lug can be fixed in place. Throughout the installation process, the high-precision design and stable structure of the tooling effectively ensure the accuracy of the U-shaped lug deflection angle, guaranteeing the installation quality and performance of the hydraulic support.

[0071] This tooling is not only suitable for the initial installation of U-shaped lugs on hydraulic supports, but can also be widely used in the inspection and maintenance of U-shaped lugs. During inspection, operators can use the tooling to quickly detect whether the deflection angle of the U-shaped lug has changed, promptly identify angle deviations caused by long-term use, and make adjustments and repairs. At the same time, the tooling's portability and ease of operation allow it to be quickly deployed in different work locations and environments, meeting the complex and ever-changing operational needs of underground coal mines.

[0072] In terms of maintenance, to ensure the long-term stable use of the tooling, it is necessary to clean and inspect it regularly. During cleaning, use a soft, damp cloth to wipe the surface of the dial 1 and pointer 6 to remove dust and stains. Avoid using corrosive cleaning agents to prevent damage to the surface coating. During inspection, pay close attention to whether the connection between the round steel 5 and the dial 1 is secure, whether the bolts 3 and nuts 4 are loose, and whether the bubble level is working properly. Worn or damaged parts, anti-loosening washers, etc., should be replaced promptly. Through scientific and reasonable maintenance, the service life of the tooling can be effectively extended, maintaining its high precision and reliability, and providing continuous protection for the safe and stable operation of the hydraulic support.

[0073] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can conceive of other specific embodiments of this utility model without creative effort, and these embodiments will all fall within the scope of protection of this utility model.
