[0022] The embodiment of the present invention provides a rack base device for a double-horizontal-arm floor-standing holding pole, ensuring the stability and safety of the holding pole during operation.

[0023] The following combines Figures 1-4 To elaborate more detailedly on the technical solutions provided by the present invention.

[0024] Embodiment 1: As Figures 1-4As 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.

[0025] 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.

[0026] 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.

[0027] 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.

[0028] For details, see Figure 2 and Figure 3As shown, the horizontal section of one L-shaped plate 10 is clamped and fixed in two adjacent first card slots 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 two adjacent first card slots 24 of the second base 2 and the third base 3. The locking plate 11 is attached to the vertical section of the L-shaped plate 10. At the same time, the second block 12 passes through the through hole 101 and is clamped and fixed in the second card slot 25. The second limiting mechanism fixes the locking plate 11 on the block base, and the locking plate 11 no longer moves.

[0029] As an alternative implementation, refer to Figure 3 As shown, the through holes 101 are arranged at intervals along the length or width direction of the L-shaped plate 10, and the positions and numbers of the second blocks 12 are set in one-to-one correspondence with the through holes 101.

[0030] As an alternative implementation, refer to Figures 2-4 As shown, the second limiting mechanism includes a limiting block 19 and a second spring 21, where: a cavity 102 is provided inside the horizontal section of the L-shaped plate 10, the second spring 21 is installed and fixed inside the cavity 102, a slider 20 is fixed to the bottom end of the limiting block 19, and the slider 20 is limited inside 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 arranged to move up and down under the drive of the second spring 21. When the slider 20 is clamped in the cavity 102, the limiting block 19 abuts against the locking plate 11, so as to cooperate with the vertical section of the block base 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.

[0031] When the second block 12 is clamped and fixed with the second card slot 25, press the limiting block 19 downward, 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 block 12 is clamped and fixed with the second card slot 25. Then remove the pressure acting on the limiting block 19, the limiting block 19 moves upward under the action of the second spring 21, the limiting block 19 abuts against the locking plate 11, and the limiting block 19 cooperates with the vertical section of the block base to clamp and fix the locking plate 11.

[0032] The clamping of the locking plate 11 on the L-shaped plate with the first card slot 24 and the second limiting mechanism connect the L-shaped plate with the pole body 5. The multi-directional connection method makes the entire frame base device form a firm whole, which can bear greater external forces and working loads, and ensures the stability and safety of the pole during operation.

[0033] As an alternative implementation, refer to Figure 1 and Figure 2As shown, among the first base 1 and the second base 2, and / or, among the third base 3 and the fourth base 4, a wedge block 6 is provided on one of them, and a wedge groove is provided on the other. The wedge block 6 is inserted and fixed to the corresponding wedge groove.

[0034] The clamping fit between the wedge block 6 and the wedge groove further positions and connects the four bases in the horizontal direction, enhancing the stability in the horizontal direction. The two wedge blocks 6 are integrally formed with the corresponding second base 2 and fourth base 4, improving the connection firmness and reducing the safety hazards caused by loosening of the connection parts.

[0035] As an alternative implementation, refer to Figure 1 and Figure 2 As shown, connection blocks 8 are fixedly provided on the outer sides of the first base 1, the second base 2, the third base 3, and the fourth base 4. Adjacent connection blocks 8 are fixedly connected by bolts 9.

[0036] Multiple pairs of adjacent connection blocks 8 are all threadedly locked and connected by bolts 9, which can further enhance the connection stability between the four bases.

[0037] As an alternative implementation, refer to Figure 1 and Figure 2 As shown, among the first base 1 and the fourth base 4, and / or, among the second base 2 and the third base 3, a connection hole 26 is provided on one of them, and a connecting rod 22 is provided on the other. A groove is provided beside the connection hole 26, and a first limiting mechanism is provided in the groove. When the connecting rod 22 is inserted into the connection hole 26, the first limiting mechanism locks the connecting rod 22.

[0038] The connecting rod 22 is inserted into the connection hole 26, and the movement of the connecting rod 22 is restricted by the first limiting mechanism, ensuring a tight and firm connection between the modules.

[0039] The longitudinal cross-sections of the connecting rod 22 and the connection hole 26 are both rectangular, and the cross-sections of the slider 20 and the cavity 102 are also rectangular. This design makes the connecting rod 22 and the slider 20 unable to rotate and can only slide stably, avoiding structural instability caused by the rotation of components and further enhancing the overall firmness of the device.

[0040] As an alternative implementation, refer to Figure 2As shown in the figure, the first limiting mechanism includes a fixed sleeve 13, a first spring 18, a movable rod 15 and a sliding plate 16, where: the fixed sleeve 13 is fixedly arranged in the groove, one end of the first spring 18 is fixed in the fixed sleeve 13, a stop block 14 is fixed at one end of the movable rod 15, the stop block 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 sliding plate 16, a triangular block 17 is arranged on the sliding plate 16, a triangular groove is arranged on the movable rod 15, when the movable rod 15 is inserted into the connecting hole 26, the triangular block 17 is inserted into the corresponding triangular groove of the fixing groove, so as to lock the connecting rod 22 in the connecting hole 26.

[0041] 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 stop block 14 to slide in the fixed sleeve 13 and compress the first spring 18. When the connecting rod 22 is inserted in place, the triangular block 17 is clamped into the corresponding triangular groove on the connecting rod 22 under the elastic force of the first spring 18, restricting the movement of the connecting rod 22 and completing the connection between the two groups of bases.

[0042] As an optional implementation manner, stress sensors are fixedly installed inside the first base 1, the second base 2, the third base 3 and the fourth base 4. The stress sensors use the Kalman filtering 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 calculations are 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 estimation at the previous moment and the system model; in the update step, the prediction result is corrected by combining the stress observation value at the current moment to obtain the optimal stress state estimation at the current moment.

[0043] Compared with the prior art, the present invention provides a frame base device for a double-flat-arm floor-mounted holding pole, having the following beneficial effects: 1. The frame base device for the double-horizontal-arm floor-mounted gin pole adopts various connection methods to ensure the overall structural stability. First, the first base 1, the second base 2, the third base 3, and the fourth base 4 are distributed in a rectangular array. The gin pole main body 5 is clamped to the first installation groove 23 of the base through the first clamping blocks 7 on the front and rear sides, initially fixing the relative position of the gin pole main body 5 and the base. Secondly, the clamping fit between the wedge-shaped blocks 6 and the wedge-shaped grooves further positions and connects the four bases in the horizontal direction, enhancing the stability in the horizontal direction. Moreover, the connecting rod 22 is inserted into the connecting hole 26, and the movement of the connecting rod 22 is restricted by the first limiting mechanism, ensuring the tight and stable connection between the modules. Finally, the clamping of the L-shaped plate and the first clamping groove 24 and the connecting mechanism connect the L-shaped plate and the gin pole main body 5. The multi-directional connection method makes the entire frame base device form a firm whole, capable of withstanding large external forces and working loads, ensuring the stability and safety of the gin pole during operation.

[0044] 2. The frame base device for the double-horizontal-arm floor-mounted gin pole is integrally formed by two wedge-shaped blocks 6 and the corresponding second base 2 and fourth base 4, improving the connection stability and reducing the safety hazards caused by loosening of the connection parts. At the same time, 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 makes the connecting rod 22 and the slider 20 unable to rotate and can only slide stably, avoiding the structural instability caused by the rotation of components and further enhancing the overall stability of the device.

[0045] 3. The frame base device for the double-horizontal-arm floor-mounted gin pole adopts a modular design and is divided into multiple modules such as the first base 1, the second base 2, the third base 3, the fourth base 4, and the gin pole main body 5. During installation, only need to assemble each module according to specific steps. For example, first perform module layout to determine the relative position, and then successively complete operations such as connecting with the gin pole main body 5, connecting the wedge-shaped block 6 and the wedge-shaped groove, and connecting the connecting rod 22 and the connecting hole 26. Each step is clear and definite, reducing the installation difficulty and improving the installation efficiency.

[0046] 4. The frame base device for the double-horizontal-arm floor-mounted gin pole has multiple components in the device adopting detachable connection methods, such as the connection block 8 connected by bolts 9, the first clamping block 7 and the first installation groove 23 in clamping connection, the wedge-shaped block 6 and the wedge-shaped groove, the L-shaped plate and the first clamping groove 24, etc. This design enables convenient disassembly and replacement of corresponding components when the equipment is maintained or a certain component is damaged, reducing the maintenance cost and difficulty, and improving the maintainability and service life of the equipment.

[0047] Embodiment 2: Please refer to Figures 1-4, A method of using a frame base device for a double-horizontal-arm floor-mounted gin pole, including the frame base device for a double-horizontal-arm floor-mounted gin pole, and the specific steps are as follows: Step 1, module layout: Place the first base 1, the second base 2, the third base 3, and the fourth base 4 in a rectangular array distribution on the installation site, and preliminarily determine their relative positions to leave a suitable space for installing the gin pole main body 5 subsequently.

[0048] Step 2, connection with the gin pole main body: Place the gin pole main body 5 between the four bases, and respectively insert the first clamping blocks 7 on the first base 1, the second base 2, the third base 3, and the fourth base 4 into the corresponding first installation grooves at both ends of the front and rear sides of the gin pole main body 5 to ensure tight clamping and preliminarily fix the relative positions of the gin pole main body 5 and the base.

[0049] Step 3, connection between the wedge block and the wedge groove: 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 these four bases in the horizontal direction.

[0050] Step 4, connection between the connecting rod 22 and the connection hole: Dock the connection holes on the third base 3 and the fourth base 4 with the connecting rods 22 on the first base 1 and the second base 2, and insert the connecting rods 22 into the connection holes. 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 will drive the stopper 14 to slide in the fixed sleeve 13 and compress the first spring 18. When the connecting rod 22 is inserted in place, the triangular block 17 will be stuck into the corresponding triangular groove on the connecting rod 22 under the elastic force of the first spring 18 to limit the movement of the connecting rod 22 and complete the connection between these two groups of bases.

[0051] Step 5, bolt fixation of the connecting block: Use bolts 9 to thread-lock and connect the connecting blocks 8 on the outer walls of the adjacent bases on both sides to further enhance the connection stability between the four bases.

[0052] Step 6, installation of the L-shaped plate: Snap the L-shaped plate 10 into the first card slots opened on the first base 1 and the third base 3, and the second base 2 and the fourth base 4 on the same side to preliminarily fix the position of the L-shaped plate 10.

[0053] Step 7, connect the main boom: Operate the connecting mechanism, press down the limiting block 19, the slider 20 slides downward in the cavity and compresses the second spring 21, so that the limiting block 19 no longer abuts against the locking plate 11. Then slide the locking plate 11, insert the second latch 12 on the locking plate 11 into the corresponding second card slots on the left and right sides of the main boom 5 through the through holes on the L-shaped plate 10, to realize the connection between the L-shaped plate 10 and the main boom 5. Release the limiting block 19, under the elastic force of the second spring 21, the slider 20 drives the limiting block 19 to move upward, and abuts against the locking plate 11 again, restricting the movement of the locking plate 11 relative to the L-shaped plate 10, completing the installation of the connecting mechanism, and making the entire frame base device form a stable whole.
