[0002] In the fully mechanized hydraulic support, the base is the part that transmits the roof pressure to the bottom plate and stabilizes the support. The existing technology often uses the main reinforcement hinge hole for positioning and welding, that is, it is necessary to open positioning holes in the edges of the outer main reinforcement plate and the inner main reinforcement plate in advance, and then penetrate the shaft, and use the shaft and the bottom plate to achieve the preliminary determination of the position of the outer main reinforcement plate and the inner main reinforcement plate, and then assemble other support components between the outer main reinforcement plate and the inner main reinforcement plate, and after the support reinforcement is fixed, the other components are welded to the corresponding outer main reinforcement plate, the inner main reinforcement plate and the bottom plate.

[0003] However, in this assembly method, the process of point-fixing the reinforcements relies on workers to hold the reinforcements by hand, resulting in poor reinforcement accuracy. Summary of the invention

[0040] In order to better explain the present invention, so as to facilitate understanding, the following Figure 1-Figure 7 , the present invention is described in detail through specific implementation methods. Figure 2 The orientation is used as a reference.

[0041] Embodiment 1:

[0042] Reference Figure 1-Figure 7An embodiment of the present invention provides an assembly tool for a base of a hydraulic support, the assembly tool for the base of the hydraulic support, the base includes a front main rib plate 1 and a rear main rib plate 2 parallel to each other, and a bottom plate 3 placed at the bottom of the front main rib plate 1 and the rear main rib plate 2, a spacing is formed between the front main rib plate 1 and the rear main rib plate 2, the assembly tool includes a limiting frame 4, a positioning pin 5 and a support rib 100; the positioning pin 5 passes through the front main rib plate 1 and the rear main rib plate 2 along the front-to-back direction, and is detachably connected to the front main rib plate 1 and the rear main rib plate 2. One end of the limiting frame 4 forms a bearing surface 400 and a positioning surface 410 that are in contact with the positioning pin 5 and are perpendicular to each other. The positioning surface 410 extends vertically, and the bearing surface 400 can be placed on the upper surface of the positioning pin 5; the other end of the limiting frame 4 extends a supporting foot 420 toward the base plate 3, so that the two ends of the limiting frame 4 are respectively supported on the positioning pin 5 and the base plate 3, and the lateral position of the limiting frame 4 is limited by the positioning surface 410; wherein, a plurality of supporting portions 430 extending along the front-to-back direction are formed on the limiting frame 4 to support the corresponding support ribs 100.

[0043] Specifically, the supporting portion 430 has a certain thickness, that is, it extends to a certain extent in the front-to-back direction to stably support the support rib 100 .

[0044] In this embodiment, the vertical position of the positioning pin 5 is fixed relative to the horizontal position of the front main rib plate 1 and the rear main rib plate 2. When the positioning surface 410 and the bearing surface 400 of the limiting frame 4 are both in contact with the positioning pin 5 and the supporting foot 420 is supported on the bottom plate 3, the lateral position of the limiting frame 4 is restricted, thereby limiting the position of the supporting portion 430; the supporting portion 430 is used to support the strut 100, so that during the welding process, the strut 100 can be stably supported without the help of workers' hands, thereby improving the work efficiency when the strut 100 is fixed; at the same time, the strut 100 is supported by the supporting portion 430 and will have a fixed connection position, which is conducive to improving the standardization of the strut 100 process, thereby improving the overall quality of the hydraulic support after assembly.

[0045] Furthermore, the present invention no longer relies on the original tooling shaft of the hydraulic support to position the front main rib plate 1 and the rear main rib plate 2, thus omitting the boring process. Only a small hole is required on the front main rib plate 1 and the rear main rib plate 2, and the size of the positioning pin 5 is much smaller than the size of the tooling shaft. Therefore, the difficulty of assembling the hydraulic support is greatly reduced, thereby improving the assembly efficiency of the hydraulic support.

[0046] The base also includes a bridge assembly 8, a cross rib assembly 9, a rib plate 10, a pad 11 and a pad 11 connected within the span; the bridge assembly 8 and the rib plate 10 both extend vertically and are perpendicular to the front main rib plate 1, and are located on both sides of the column socket 6; the cross rib assembly 9 is connected to the bottom plate 3 and is located between the bridge assembly 8 and the rib plate 10, and the pad 11 is connected to the top surface of the cross rib assembly 9, and the pad 11 can support the column socket 6.

[0047] The bridge assembly 8 and the rib plate 10 are used to enhance the strength and rigidity of the hydraulic support, prevent deformation or damage due to excessive force, and help to disperse and withstand the various forces and moments generated by the hydraulic support during operation. The bottom end of the cross rib assembly 9 is supported on the bottom plate 3 to ensure the stability of the entire hydraulic support. The top surface of the cross rib assembly 9 is connected to the pad 11, and the top surface of the pad 11 forms a supporting plane for the column socket 6, which realizes a stable support for the column socket 6.

[0048] By setting the above components, the overall strength of the hydraulic support after assembly can be effectively guaranteed, and the reliability of the hydraulic support can be improved.

[0049] Specifically, the limiting frame 4 can be set as an integrally formed structure, or as a split structure, such as making the supporting portion 430 detachably connected to the main body of the limiting frame 4, and the connecting sleeve 440 can be connected to the supporting portion 430, so that the connecting sleeve 440 is sleeved on the main body of the limiting frame 4, and the shell of the connecting sleeve 440 is set as a rubber sleeve, so that the position of the supporting portion 430 can be more flexibly adjusted.

[0050] Furthermore, a connection groove may be provided on the body of the limiting frame 4, and the connection groove corresponds to the position of the connection sleeve 440, so that it can be accurately connected to a predetermined position. A plurality of connection grooves may be provided according to the assembly requirements of different types of hydraulic supports.

[0051] Embodiment 2:

[0052] Reference Figure 1-Figure 7 In addition to all the technical solutions of the above embodiments, the embodiments of the present invention further have the following technical solutions:

[0053] The supporting parts 430 are all located on one side of the positioning pin 5, and the supporting parts 430 form a make way opening on the side facing the positioning pin 5. The positioning surface 410 is located on the side of the positioning pin 5 close to the supporting part 430, so that the positioning pin 5 and the support rib 100 can make way for the assembly process of the limiting frame 4, thereby improving the disassembly and assembly efficiency of the limiting frame 4.

[0054] The protrusion extending laterally from the limiting frame 4 forms a supporting portion 430, and the top plane of the protrusion intersects with the vertical plane of the limiting frame 4. In this way, the top surface of the protrusion can support the support rib 100, and the vertical plane of the limiting frame 4 can limit the lateral position of the support rib 100. In addition, this structure can also enable the positioning pin 5 and the support rib 100 to make way for the assembly process of the limiting frame 4.

[0055] Embodiment 3:

[0056] Reference Figure 1-Figure 7 In addition to all the technical solutions of any of the above embodiments, the embodiments of the present invention further have the following technical solutions:

[0057] The bearing surface 400, the positioning surface 410 and the supporting portion 430 are all magnetic, and the support rib 100 and the positioning pin 5 are both made of magnetic materials, so that the supporting portion 430 and the support rib 100 can be adsorbed to each other, and the positioning surface 410 and the positioning pin 5 can be adsorbed to each other, thereby improving the installation stability of the limiting frame 4, and also improving the stability of the support rib 100 on the supporting portion 430, thereby improving the assembly accuracy of the support rib 100, improving the assembly efficiency of the entire hydraulic support, and simplifying the assembly process, making the entire structure easier to operate.

[0058] Embodiment 4:

[0059] Reference Figure 1-Figure 7 In addition to all the technical solutions of any of the above embodiments, the embodiments of the present invention further have the following technical solutions:

[0060] The base also includes a column socket 6 connected to the bottom plate 3 and located within the spacing. The axis of the locating pin 5 coincides with the axis of the column socket 6. This provides a basis for determining the position of the column socket 6 using the locating pin 5, and also realizes the multiple uses of the locating pin 5, which is beneficial to reducing the assembly cost of the hydraulic support.

[0061] The assembly tool also includes a positioning plate 7 that can be set within the gear spacing, and the positioning pin 5 can pass through the positioning plate 7 and be rotatably connected to the positioning plate 7; the positioning plate 7 forms an arc surface 700 that matches the top surface of the column socket 6 on the side facing the column socket 6, and the arc surface 700 and the swing axis of the positioning plate 7 coincide with the positioning axis. In this way, by swinging the positioning plate 7, it can be adjusted to an angle suitable for the assembly of the column socket 6, and then the positioning plate 7 is rotated again to make the top surface of the column socket 6 cooperate with the arc surface 700. At the same time, after the bottom surface of the column socket 6 is stably supported on the bottom plate 3, the position of the column socket 6 will be accurately limited, thereby ensuring the assembly efficiency and assembly accuracy of the column socket 6.

[0062] Specifically, the arc surface 700 also needs to have a certain front-to-back and left-to-right extension area to ensure that it can be stably fitted with the top surface of the column socket 6 .

[0063] Furthermore, by utilizing the positioning pin 5, limiting frame 4 and positioning plate 7 in the present invention to fix the support rib 100 and the positioning column socket 6, the entire process is smooth and efficient. The positioning pin 5 only needs to be removed once when penetrating the positioning plate 7, thereby improving the assembly efficiency of the hydraulic support. The positioning plate 7 and the limiting frame 4 share the positioning pin 5, which saves costs while unifying the assembly reference of the support rib 100 and the positioning plate 7, making the two more integrated, thereby facilitating improving the assembly accuracy of the two.

[0064] Embodiment 5:

[0065] Reference Figure 1-Figure 7In addition to all the technical solutions of any of the above embodiments, the embodiments of the present invention further have the following technical solutions:

[0066] The bracing bar 100 is a prefabricated component, and the bracing bar 100 is a standard length model.

[0067] In the prior art, the bracing bars 100 are generally waste steel bars at the construction site, which are roughly measured by workers and then cut on site. The poor dimensional standardization of the bracing bars 100 leads to poor assembly accuracy, and the on-site cutting of the bracing bars 100 is not conducive to improving assembly efficiency.

[0068] In this embodiment, the support rib 100 is set as a prefabricated component of standard length, that is, the length is equal to the spacing between the front main rib plate 1 and the rear main rib plate 2. This can greatly improve the assembly accuracy. Since the support rib 100 does not need to be cut on site, the assembly efficiency can also be improved.

[0069] Embodiment 6:

[0070] Reference Figure 1-Figure 7 In addition to all the technical solutions of any of the above embodiments, the embodiments of the present invention further have the following technical solutions:

[0071] The front main rib plate 1 and the rear main rib plate 2 are coaxially provided with a first connecting hole 200 and a second connecting hole 210; four support ribs 100 are provided; two of the support ribs 100 are provided on the upper and lower sides of the positioning pin 5 and close to the positioning pin 5, and the other two support ribs 100 are respectively close to the first connecting hole 200 and the second connecting hole 210.

[0072] In this embodiment, by connecting two support ribs 100 to the upper and lower sides of the locating pin 5 respectively, it can ensure that the front main rib plate 1 and the rear main rib plate 2 on the upper and lower sides of the locating pin 5 are supported, and the offset problem of the locating pin 5 can be corrected to a certain extent.

[0073] The first connecting hole 200 and the second connecting hole 210 are both mounting holes for connecting the hydraulic support to the tooling shaft. The support ribs 100 are arranged near the two connecting holes to ensure the coaxiality of the front and rear paired first connecting holes 200 and second connecting holes 210, which is conducive to more convenient and accurate connection of the tooling shaft.

[0074] Embodiment 7:

[0075] Figure 1-Figure 7 In addition to providing a hydraulic support assembly method, the embodiment of the present invention uses any one of the above-mentioned assembly tools for the base of the hydraulic support, and the assembly method includes:

[0076] S1: The front main rib plate 1 and the rear main rib plate 2 are arranged on the bottom plate 3, and the positioning pins 5 are penetrated;

[0077] S2: Assemble the bridge assembly 8, the cross rib assembly 9 and the rib plate 10 at the corresponding position of the gear spacing, support the limiting frame 4 on the positioning pin 5 and the bottom plate 3, and position the limiting frame 4 laterally through the positioning surface 410;

[0078] S3: placing the support ribs 100 on the supporting portion 430 and fastening all the support ribs 100;

[0079] S4: Remove the limiting frame 4 and weld the bridge assembly 8, the cross rib assembly 9 and the rib plate 10;

[0080] S5: Assemble and weld the pad 11;

[0081] S6: Make the positioning pin 5 pass through the positioning plate 7, swing the positioning plate 7 and assemble and weld the column socket 6;

[0082] S7: Remove the positioning pin 5, the positioning plate 7 and the support rib 100.

[0083] In this embodiment, the method makes full use of the assembly tool for the base of the hydraulic support mentioned above, as follows:

[0084] S1: The front main rib plate 1 and the rear main rib plate 2 are arranged on the bottom plate 3, and the positioning pins 5 are penetrated.

[0085] The front main rib plate 1 and the rear main rib plate 2 are placed on the bottom plate 3, and their positions are preliminarily determined by inserting the positioning pins 5. The positioning pins 5 are used to ensure the accuracy and stability of subsequent assembly and to control the overlap between the front main rib plate 1 and the rear main rib plate 2.

[0086] S2: Assemble the bridge assembly 8, the cross rib assembly 9 and the rib plate 10 at corresponding positions within the gear span, support the limiting frame 4 on the positioning pin 5 and the bottom plate 3, and position the limiting frame 4 laterally through the positioning surface 410.

[0087] In this step, the bridge assembly 8, the cross rib assembly 9 and the rib plate 10 are preferably assembled at corresponding positions between the installation limit frames 4. After this process is completed, the preliminary preparations for the assembly of the hydraulic support are completed.

[0088] S3: Place the supporting ribs 100 on the supporting portion 430 and secure all the supporting ribs 100 .

[0089] The support rib 100 is accurately positioned in the supporting portion 430, so that the support rib 100 is kept at a predetermined position relative to the front main rib plate 1 and the rear main rib plate 2, which is beneficial to improving the support accuracy and reliability of the front main rib plate 1 and the rear main rib plate 2. After the support rib 100 is fixed, the position of the front main rib plate 1 and the rear main rib plate 2 relative to the bottom plate 3 can be limited.

[0090] S4: Remove the limiting frame 4 and weld the bridge assembly 8, the cross rib assembly 9 and the rib plate 10.

[0091] When the support bar 100 provides stable support, the limiting frame 4 can be removed. Then, the bridge assembly 8, the cross bar assembly 9 and the rib plate 10 are welded together to form the main structure of the hydraulic support.

[0092] S5: Assemble and weld the backing plate 11.

[0093] In this step, the pad 11 is assembled in place and welded. The pad 11 is designed to enhance the stability of the structure and disperse stress, ensuring that the hydraulic support can withstand various forces and moments during operation.

[0094] When assembling the backing plate 11 , it can be swung and rotated to avoid interference with the support ribs 100 .

[0095] S6: Make the positioning pin 5 pass through the positioning plate 7, swing the positioning plate 7 and assemble and weld the column socket 6.

[0096] In this step, the positioning pin 5 passes through the positioning plate 7, and the position of the column socket 6 is accurately positioned by swinging the positioning plate 7. Then, the column socket 6 is assembled and welded in the correct position. This step ensures the accuracy and stability of the column socket 6.

[0097] Specifically, the column socket 6 is positioned by swinging the positioning plate 7 , so that the column socket 6 has only one connection position under the premise of ensuring close fit with the pad 11 , thereby ensuring the accuracy of the position of the column socket 6 .

[0098] S7: Remove the positioning pin 5, the positioning plate 7 and the support rib 100.

[0099] At this point, the structure of the hydraulic support is stable enough, and no additional support is required from the support ribs 100. The positioning pins 5 and the positioning plates 7 are no longer required to remain on the support.

[0100] Please note that although these steps are performed in a certain order, in actual operation, adjustments may be required, and the adjusted method should also be within the scope of protection of the present invention.

[0101] In summary, this hydraulic support assembly method fully utilizes the various components and functions in the assembly tooling through a series of orderly steps, ensuring the precise assembly and stable performance of the hydraulic support.
