[0034] The embodiment of the present invention provides a rack base device for a double-horizontal-arm floor-standing mast, which ensures the stability and safety of the mast during operation.

[0035] The following combination Figure 1-Figure 4 The technical solution provided by the present invention is described in more detail.

[0036] Embodiment 1:

[0037] like Figure 1-Figure 4 As shown, the rack base device for a double-horizontal-arm ground-mounted pole holding pole provided by the present invention includes a first base 1, a second base 2, a third base 3, a fourth base 4, a pole holding pole body 5, a block base and a locking plate 11. The first base 1, the second base 2, the third base 3 and the fourth base 4 are detachably fixedly connected, and an installation space is surrounded by the middle of the four. The block base (L-shaped plate 10) and the pole holding pole body 5 are located in the installation space. First installation grooves 23 are provided on opposite sides of the pole holding pole body 5. First clamping blocks 7 are provided on the inner walls of the first base 1, the second base 2, the third base 3 and the fourth base 4, and the first clamping blocks 7 are clamped in the corresponding first installation grooves 23. Two groups of block bases are respectively clamped and fixed to the other two sides of the pole holding pole body 5. The locking plate 11 can be inserted into the pole holding pole body 5. When the locking plate 11 is fixed to the block base, the locking plate 11 can be clamped and fixed to the pole holding pole body 5.

[0038] In this embodiment, the rack base assembly for a double-arm floor-standing mast consists of a first base 1, a second base 2, a third base 3, and a fourth base 4, which enclose an installation space. The mast body 5 is secured to the first mounting slots 23 by first clamping blocks 7 on its front and rear sides, preliminarily fixing the relative positions of the mast body 5 and the four bases. The clamping block bases are clamped into the installation space, and the locking plates 11 on the clamping bases are clamped into the mast body 5. This ensures that all four sides of the mast body 5 are securely fixed, enhancing horizontal stability. This multi-faceted connection ensures that the rack base assembly forms a solid, integrated unit capable of withstanding significant external forces and workloads, ensuring the stability and safety of the mast during operation.

[0039] As an alternative embodiment, see Figure 2 As shown, first card slots 24 are provided on the inner sides of the first base 1 , the second base 2 , the third base 3 and the fourth base 4 , and all the first card slots 24 enclose an installation space.

[0040] As an alternative embodiment, see Figure 2 、 Figure 3 and Figure 4 As shown, the block base includes an L-shaped plate 10, the horizontal section of the L-shaped plate 10 is fixed in two adjacent first slots 24, and a through hole 101 is provided on the vertical section of the L-shaped plate 10; Figure 2 A second card slot 25 is provided on both sides of the holding pole body 5 facing the card block base, and a second card block 12 is provided on the locking plate 11. The second card block 12 passes through the through hole 101 and is fixed in the corresponding second card slot 25; a second limiting mechanism is provided on the card block base, and the second limiting mechanism fixes the locking plate 11 to the card block base.

[0041] For details, see Figure 2 and Figure 3 As shown, the horizontal section of one L-shaped plate 10 is clamped and fixed in the two adjacent first clamping grooves 24 of the first base 1 and the fourth base 4, and the horizontal section of the other L-shaped plate 10 is clamped and fixed in the two adjacent first clamping grooves 24 of the second base 2 and the third base 3. The locking plate 11 is fitted on the vertical section of the L-shaped plate 10, and at the same time, the second clamping block 12 passes through the through hole 101 and is clamped and fixed in the second clamping groove 25. The second limiting mechanism fixes the locking plate 11 on the clamping block base, and the locking plate 11 no longer moves.

[0042] As an alternative embodiment, see Figure 3 As shown, the through holes 101 are arranged at intervals along the length direction or the width direction of the L-shaped plate 10 , and the positions and numbers of the second clamping blocks 12 are arranged in a one-to-one correspondence with the through holes 101 .

[0043] As an alternative embodiment, see Figure 2-Figure 4 As shown, the second limiting mechanism includes a limiting block 19 and a second spring 21, wherein: a cavity 102 is provided in the horizontal section of the L-shaped plate 10, the second spring 21 is mounted and fixed in the cavity 102, and a slider 20 is fixed to the bottom end of the limiting block 19. The slider 20 is limited in the cavity 102 and abuts against the free end of the second spring 21; under the action of an external force, the limiting block 19 can be raised and lowered under the drive of the second spring 21. When the slider 20 is engaged in the cavity 102, the limiting block 19 abuts against the locking plate 11, thereby cooperating with the vertical section of the base of the blocking block to clamp and fix the locking plate 11. The cross-sections of the slider 20 and the cavity 102 are both rectangular, so that the slider 20 cannot rotate, that is, it can slide stably.

[0044] When the second clamping block 12 is clamped and fixed with the second clamping groove 25, the limit block 19 is pressed downward, and the slider 20 slides downward in the cavity 102 and compresses the second spring 21. At this time, the locking plate 11 can slide along the clamping base until the second clamping block 12 is clamped and fixed with the second clamping groove 25. Then the pressure on the limit block 19 is removed, and the limit block 19 moves upward under the action of the second spring 21. The limit block 19 is abutted against the locking plate 11, and the limit block 19 cooperates with the vertical section of the clamping block base to clamp and fix the locking plate 11.

[0045] The locking plate 11 on the L-shaped plate is engaged with the first slot 24, and the second limiting mechanism connects the L-shaped plate to the boom body 5. The multi-directional connection method makes the entire rack base device form a solid whole, which can withstand large external forces and workloads, ensuring the stability and safety of the boom during operation.

[0046] As an alternative embodiment, see Figure 1 and Figure 2 As shown, a wedge block 6 is provided on one of the first base 1 and the second base 2, and / or a wedge groove is provided on the other one of the third base 3 and the fourth base 4, and the wedge block 6 is plugged and fixed into the corresponding wedge groove.

[0047] The engagement of the wedge blocks 6 with the wedge grooves further positions and connects the four bases horizontally, enhancing horizontal stability. The two wedge blocks 6 are integrally formed with the corresponding second and fourth bases 2 and 4, improving the stability of the connection and reducing safety hazards caused by loose connections.

[0048] As an alternative embodiment, see Figure 1 and Figure 2 As shown, connecting blocks 8 are fixed to the outer sides of the first base 1 , the second base 2 , the third base 3 and the fourth base 4 , and adjacent connecting blocks 8 are fixedly connected by bolts 9 .

[0049] Multiple pairs of adjacent connection blocks 8 are connected by threaded locking of bolts 9, which can further enhance the connection stability between the four bases.

[0050] As an alternative embodiment, see Figure 1 and Figure 2 As shown, between the first base 1 and the fourth base 4, and / or between the second base 2 and the third base 3, one of them is provided with a connecting hole 26, and the other one is provided with a connecting rod 22, and a groove is provided on the side of the connecting hole 26, and a first limiting mechanism is provided in the groove. When the connecting rod 22 is inserted into the connecting hole 26, the first limiting mechanism locks the connecting rod 22.

[0051] The connecting rod 22 is inserted into the connecting hole 26 , and the movement of the connecting rod 22 is limited by the first limiting mechanism, thereby ensuring that the connection between the modules is tight and stable.

[0052] The longitudinal sections of the connecting rod 22 and the connecting hole 26 are both rectangular, and the cross sections of the slider 20 and the cavity 102 are also rectangular. This design prevents the connecting rod 22 and the slider 20 from rotating and can only slide stably, avoiding structural instability caused by the rotation of components and further enhancing the overall stability of the device.

[0053] As an alternative embodiment, see Figure 2 As shown, the first limiting mechanism includes a fixed sleeve 13, a first spring 18, a movable rod 15 and a slide plate 16, wherein: the fixed sleeve 13 is fixedly arranged in the groove, one end of the first spring 18 is fixed in the fixed sleeve 13, and one end of the movable rod 15 is fixed with a stopper 14, the stopper 14 is located in the fixed sleeve 13, and abuts against the telescopic end of the first spring 18, the other end of the movable rod 15 is fixedly connected to the slide plate 16, a triangular block 17 is provided on the slide plate 16, and a triangular groove is provided on the movable rod 15. When the movable rod 15 is inserted into the connecting hole 26, the triangular block 17 and the corresponding triangular groove are plugged into the fixed groove, thereby locking the connecting rod 22 in the connecting hole 26.

[0054] Insert the connecting rod 22 into the connecting hole 26. During the insertion process, the first limiting mechanism will play a role. When the connecting rod 22 is inserted, the triangular block 17 will be squeezed, and the movable rod 15 drives the stopper 14 to slide in the fixed sleeve 13 and compress the first spring 18. When the connecting rod 22 is inserted into place, the triangular block 17 is stuck in the corresponding triangular groove on the connecting rod 22 under the elastic force of the first spring 18, limiting the movement of the connecting rod 22 and completing the connection between the two sets of bases.

[0055] As an optional implementation, stress sensors are fixed inside the first base 1, the second base 2, the third base 3 and the fourth base 4. The stress sensors use a Kalman filter algorithm to process the collected stress data to improve the accuracy and reliability of the data. Specifically, according to the observation equation and state equation of the stress sensor, iterative calculation is performed through two steps of prediction and update. In the prediction step, the stress state at the current moment is predicted based on the stress state estimate at the previous moment and the system model; in the update step, the prediction result is corrected in combination with the stress observation value at the current moment to obtain the optimal stress state estimate at the current moment.

[0056] Compared with the prior art, the present invention provides a rack base device for a double-horizontal-arm floor-standing mast, which has the following beneficial effects:

[0057] 1. This rack base assembly for a dual-arm floor-standing mast utilizes multiple connection methods to ensure a stable overall structure. First, the first base 1, second base 2, third base 3, and fourth base 4 are arranged in a rectangular array. The mast body 5 engages with the first mounting slots 23 of the bases via first retaining blocks 7 on its front and rear sides, preliminarily securing the relative positions of the mast body 5 and the bases. Second, the engagement of the wedge blocks 6 with the wedge slots further positions and connects the four bases horizontally, enhancing horizontal stability. Furthermore, the connecting rod 22 is inserted into the connecting hole 26, and its movement is restricted by a first limiting mechanism, ensuring a tight and secure connection between the modules. Finally, the L-shaped plate engages with the first retaining slot 24, and the connecting mechanism connects the L-shaped plate to the mast body 5. These multi-faceted connection methods form a solid, integrated unit capable of withstanding significant external forces and workloads, ensuring the stability and safety of the mast during operation.

[0058] 2. This dual-arm floor-standing mast frame mount assembly is manufactured by integrally molding two wedge-shaped blocks 6 with the corresponding second and fourth bases 2 and 4, enhancing the stability of the connection and reducing safety hazards caused by loose connections. Furthermore, the connecting rod 22 and connecting hole 26 are both rectangular in longitudinal cross-section, and the slider 20 and cavity 102 also have rectangular cross-sections. This design prevents the connecting rod 22 and slider 20 from rotating, allowing them to slide stably. This prevents structural instability caused by component rotation and further enhances the overall stability of the assembly.

[0059] 3. This dual-arm floor-standing mast frame base assembly utilizes a modular design, consisting of multiple modules: a first base 1, a second base 2, a third base 3, a fourth base 4, and a mast body 5. Installation requires simply assembling each module according to specific procedures. First, the modules are laid out and their relative positions determined. Then, the modules are connected to the mast body 5, the wedge block 6 is connected to the wedge slot, and the connecting rod 22 is connected to the connecting hole 26. Each step is clearly defined, reducing installation difficulty and improving efficiency.

[0060] 4. This dual-arm floor-standing mast frame base assembly utilizes detachable connections between multiple components, including the connecting block 8 connected by bolts 9, the first clamping block 7 and the first mounting slot 23, the wedge block 6 and the wedge slot, and the L-shaped plate and the first clamping slot 24. This design facilitates removal and replacement of components during equipment maintenance or component damage, reducing maintenance costs and difficulty while increasing the maintainability and service life of the equipment.

[0061] Example 2:

[0062] See also Figure 1-4A method for using a rack base device for a double-horizontal-arm floor-standing mast includes the following specific steps:

[0063] Step 1: Module layout: Place the first base 1, second base 2, third base 3, and fourth base 4 in a rectangular array at the installation site, preliminarily determine their relative positions, and leave appropriate space for the subsequent installation of the pole body 5.

[0064] Step 2: Connect to the pole body: Place the pole body 5 between the four bases. Insert the first clamping blocks 7 on the first base 1, second base 2, third base 3, and fourth base 4 into the corresponding first mounting grooves on the front and rear ends of the pole body 5, ensuring a tight connection. This will initially fix the relative positions of the pole body 5 and the bases.

[0065] Step three, connecting the wedge blocks and the wedge grooves: dock the wedge grooves on the first base 1 and the third base 3 with the wedge blocks 6 on the second base 2 and the fourth base 4, and insert the wedge blocks 6 into the wedge grooves to further position and connect the four bases in the horizontal direction.

[0066] Step 4, connect the connecting rod 22 with the connecting hole: dock the connecting holes on the third base 3 and the fourth base 4 with the connecting rod 22 on the first base 1 and the second base 2, and insert the connecting rod 22 into the connecting hole. During the insertion process, the first limiting mechanism will play a role. When the connecting rod 22 is inserted, the triangular block 17 will be squeezed, and the movable rod 15 drives the stopper 14 to slide in the fixed sleeve 13 and compress the first spring 18. When the connecting rod 22 is inserted into place, the triangular block 17 is stuck in the corresponding triangular groove on the connecting rod 22 under the elastic force of the first spring 18, limiting the movement of the connecting rod 22 and completing the connection between the two groups of bases.

[0067] Step 5, bolt fixing of the connecting blocks: Use bolts 9 to thread-lock the connecting blocks 8 on the outer walls of both sides of adjacent bases to further enhance the connection stability between the four bases.

[0068] Step 6: Install the L-shaped plate: insert the L-shaped plate 10 into the first slots on the first base 1 and the third base 3 , the second base 2 and the fourth base 4 on the same side to preliminarily fix the position of the L-shaped plate 10 .

[0069] Step 7: Connect the pole body: Operate the connecting mechanism and press the limit block 19 downward. The slider 20 slides downward in the cavity and compresses the second spring 21, so that the limit block 19 no longer contacts the locking plate 11. Then, slide the locking plate 11 and insert the second clamping blocks 12 on the locking plate 11 through the through holes on the L-shaped plate 10 into the corresponding second clamping grooves on the left and right sides of the pole body 5 to connect the L-shaped plate 10 to the pole body 5. Release the limit block 19. Under the elastic force of the second spring 21, the slider 20 drives the limit block 19 to move upward and contact the locking plate 11 again, limiting the movement of the locking plate 11 relative to the L-shaped plate 10. The installation of the connecting mechanism is completed, and the entire rack base device forms a stable whole.
