DETAILED DESCRIPTION

[0022] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0023] Please see attached Figure 1 and attached Figure 2, an auxiliary supporting device, comprising a column 1, a swivel bridge plate 2, a gear ring 3, a threaded rod 4, a flip plate 11, a gear 21, a locking assembly and a height adjustment assembly; the upper end of the column 1 is rotatably connected to the bottom center of the swivel bridge plate 2, the gear ring 3 is coaxially installed on the outer wall of the column 1, the upper end of the threaded rod 4 is rotatably connected to the bottom of the swivel bridge plate 2 through a rotating bearing, and a plurality of threaded rods 4 are arranged at equal intervals on the outer side of the column 1 along the circumference of the column 1; a plurality of threaded rods 4 are coaxially connected with gears 21, and a plurality of gears 21 are meshed and transmission-connected with the gear ring 3; a plurality of threaded rods 4 are movably connected with locking assemblies, and the locking assemblies can be locked and connected with the gear ring 3; the swivel bridge plate 2 is a hollow plate structure with an opening at the top, and a plurality of groups of height adjustment assemblies are respectively installed in the swivel bridge plate 2, and the flip plate 11 is movably installed at the top opening of the swivel bridge plate 2 through a plurality of groups of height adjustment assemblies.

[0024] Preferably, a bottom plate can be provided at the bottom of the column 1 to increase the contact area with the support surface, thereby improving the stability and reliability of the support. The middle part of the rotating bridge plate 2 is installed on the column 1, and the column 1 provides the main support to the middle part of the rotating bridge plate 2, and the threaded rod 4 provides a certain amount of auxiliary support to the side of the rotating bridge plate 2.

[0025] When the swivel bridge plate 2 turns, the locking assembly locks the gear ring 3 and the gear 21, and the threaded rod 4 rotates synchronously with the swivel bridge plate 2. The meshing transmission of the gear 21 and the gear ring 3 ensures the steering stability of the swivel bridge plate 2. After the rotation is in place, the gear ring 3 and the gear 21 are locked by the locking assembly to ensure the stable setting of the swivel bridge plate 2. Preferably, two sets of locking assemblies can be symmetrically arranged, and the number of locking assemblies can also be adjusted according to actual needs.

[0026] The height and angle of the flip plate 11 can be adjusted by several groups of height adjustment components to meet the use requirements of the rotating bridge plate 2. The height adjustment components can be symmetrically arranged in two groups, and the number of height adjustment components can also be adjusted according to actual needs.

[0027] The auxiliary support device of the utility model is made of high-strength steel material as a whole, and the corresponding material can be selected according to the load requirements of the engineering design. It has high structural strength, strong bearing capacity, and stable and reliable support.

[0028] Please see attached Figure 1 To Attachment Figure 4Each group of the locking components includes a second disc 7, a positioning column 8 and a rotating mechanism; a through hole (not shown in the figure) is formed at the center of the second disc 7 for the threaded rod 4 to pass through, and the second disc 7 can be lifted and sleeved on the threaded rod 4 through the rotating mechanism, and can be fixed to the bottom of the gear 21 by a first bolt 10. A plurality of positioning columns 8 are arranged at intervals at the edge of the second disc 7; a plurality of positioning holes 9 are formed at intervals at the edge of the ring gear 3, and the positioning columns 8 can be inserted into the positioning holes 9, so that the ring gear 3 and the second disc 7 are locked and connected.

[0029] The rotating mechanism is used to rotate relative to the threaded rod 4, and the second disc 7 is lowered by thread transmission, so that the positioning column 8 is disengaged from the positioning hole 9, thereby releasing the lock on the ring gear 3, and then releasing the lock on the gear 21, so that the rotating bridge plate 2 can rotate. Similarly, the second disc 7 can be raised by thread transmission, so that the positioning column 8 is inserted into the positioning hole 9, thereby locking the ring gear 3 and the gear 21, so that the rotating bridge plate 2 cannot rotate.

[0030] After locking the gear ring 3, the second disc 7 is fixed to the bottom of the gear 21 by the first bolt 10, and the second disc 7 will not fall off, thereby ensuring the reliability of locking.

[0031] The second disc 7 is a circular structure, and the edge of the second disc 7 intersects below the edge of the gear ring 3. The number of positioning posts 8 and positioning holes 9 can be adaptively set according to actual needs. When the swivel bridge plate 2 rotates, the positioning posts 8 rotate synchronously therewith. Due to the meshing of the gear 21 and the gear ring 3, the positioning posts 8 rotate along the circumference of the gear ring 3, so that the positioning posts 8 can be inserted into the positioning holes 9.

[0032] Please see attached Figure 1 , Attachment Figure 2 and attached Figure 4 The rotating mechanism includes a first disc 5, a connecting rod 6 and a rotating threaded block 20; the rotating threaded block 20 is sleeved on the threaded rod 4 by threaded connection, the first disc 5 is rotatably mounted on the bottom of the rotating threaded block 20 through a rotating bearing, and the threaded rod 4 passes through the central through hole of the first disc 5; the first disc 5 is located parallel to the second disc 7 and the positioning column 8, and a plurality of connecting rods 6 are connected between the first disc 5 and the second disc 7 at intervals.

[0033] Preferably, two connecting rods 6 can be symmetrically arranged, and the number of connecting rods 6 can also be adjusted according to actual needs. When the connecting rod 6 is arranged, it should be placed outside the gear 21 to avoid interfering with the rotation of the gear 21.

[0034] When the rotating threaded block 20 rotates relative to the threaded rod 4, the rotation of the rotating threaded block 20 is converted into axial linear motion along the threaded rod 4 by thread transmission, so that the rotating threaded block 20 is controlled to rise or fall by the forward or reverse rotation of the rotating threaded block 20, and the first disc 5, the connecting rod 6 and the second disc 7 are driven to rise or fall synchronously, so that the positioning column 8 can be inserted into or out of the positioning hole 9.

[0035] Please see attached Figure 2 Each group of the height adjustment components includes a slope block 12, a push plate 14 and a transmission mechanism. The slope block 12 is installed on the bottom surface of the flip plate 11. The bottom of the slope block 12 and the top of the push plate 14 are matching inclined structures, so that the push plate 14 is slidably set at the bottom of the slope block 12; a first slide groove 13 is formed at the bottom of the rotating bridge plate 2, and the transmission mechanism is embedded in the first slide groove 13, and the bottom of the push plate 14 is connected to the transmission mechanism.

[0036] Preferably, the slope block 12 can be a slope block with a right triangle cross-section. The bottom slope of the slope block 12 can be adaptively adjusted according to actual adjustment requirements, and the top slope of the push plate 14 is consistent with the bottom slope of the slope block 12.

[0037] The transmission mechanism is used to drive the push plate 14 to move horizontally. When the push plate 14 moves from the thin end to the thick end of the slope block 12, the relative sliding adjustment of the inclined surface structure is used to push the flip plate 11 upward. When the push plate 14 moves from the thick end to the thin end of the slope block 12, the flip plate 11 is lowered by its own weight, thereby achieving height adjustment of the flip plate 11.

[0038] For the two sets of height adjustment components, the angle adjustment of the flip plate 11 can be achieved through different degrees of height adjustment, and the flipping function can be realized to meet the construction requirements.

[0039] Please see attached Figure 2 The transmission mechanism includes a reciprocating screw 15, one end of which is rotatably installed in the first slide groove 13 through a rotating bearing, and the other end of the reciprocating screw 15 extends to the outside of the rotating bridge plate 2 and is connected to a handwheel; a screw hole (not shown in the figure) matching the reciprocating screw 15 is formed at the bottom of the pushing plate 14, so that the bottom of the pushing plate 14 can be movably set in the first slide groove 13 through the reciprocating screw 15.

[0040] The reciprocating screw rod 15 can rotate under the control of a hand wheel, and the hand wheel can also be replaced by a motor to control the stable rotation of the reciprocating screw rod 15. While the reciprocating screw rod 15 rotates, the horizontal movement of the push plate 14 along the first slide groove 13 is achieved by screw hole transmission.

[0041] The cross-sectional shape and size of the first slide groove 13 match the shape and size of the push plate 14, thereby preventing the push plate 14 from rotating with the reciprocating screw 15 and ensuring the linear translation of the push plate 14, so that it can cooperate with the slope block 12 to adjust the height and angle of the flip plate 11.

[0042] Please see attached Figure 2 The bottom of the rotating bridge plate 2 is formed with a plurality of threaded holes 17 at intervals, and the bottom of the push plate 14 is also formed with threaded holes 17. The bottom of the push plate 14 is locked and fixed to the rotating bridge plate 2 through the threaded holes 17 by the second bolts 16.

[0043] The push plate 14 is locked on the rotating bridge plate 2 by the second bolt 16, so as to ensure that the height of the flip plate 11 remains unchanged and the use safety of the flip plate 11 is ensured. The number, spacing and arrangement position of the threaded holes 17 can be determined according to the translation range of the push plate 14.

[0044] Please see attached Figure 2 A limiting circular groove 19 is formed on the top surface of the column 1, and the limiting circular groove 19 is a circular ring structure with an inverted T-shaped cross-section; a plurality of inverted T-shaped limiting blocks 18 are formed at intervals on the bottom surface of the rotating bridge plate 2, so that the plurality of limiting blocks 18 can be slidably embedded in the limiting circular groove 19.

[0045] When the rotating bridge plate 2 rotates, the plurality of limit blocks 18 slide along the limit circular grooves 19 of the annular structure, thereby limiting the lateral displacement of the rotating bridge plate 2 and improving the rotation and support stability of the rotating bridge plate 2.

[0046] Please see attached Figure 2 A limiting center groove 22 is provided at the center of the top surface of the column 1, and a limiting center block 23 is provided at the center of the bottom surface of the rotating bridge plate 2. The limiting center block 23 is matched and inserted into the limiting center groove 22.

[0047] The limiting center block 23 and the limiting center groove 22 can adopt a cylindrical structure with an inverted T-shaped cross-section. The limiting center block 23 can rotate in the limiting center groove 22, further improving the rotation and support stability of the rotating bridge plate 2.

[0048] Please see attached Figure 1 To Attachment Figure 4 , the usage method and working principle of the utility model are:

[0049] When the rotating bridge plate 2 needs to be rotated and adjusted, first rotate and remove the two first bolts 10, then rotate the two rotating threaded blocks 20 to move downward on the outside of the threaded rod 4, and the rotating threaded blocks 20 drive the first disc 5 to move downward, and the first disc 5 drives the second disc 7 to move downward through the connecting rod 6, thereby making the second disc 7 drive the positioning column 8 to disengage from the positioning hole 9 in the gear ring 3.

[0050] Then the swivel bridge plate 2 is rotated so that the threaded rod 4 at the bottom is driven by the gear 21 to rotate and support along the ring gear 3. At the same time, the swivel bridge plate 2 drives the limit block 18 to slide and limit in the limit circular groove 19, and the limit center block 23 rotates in the limit center groove 22. After the swivel bridge plate 2 is adjusted to the required position, the rotating threaded block 20 is rotated to drive the first disc 5 to move upward on the outside of the threaded rod 4, and the second disc 7 is driven to move upward through the connecting rod 6, so that the positioning column 8 on the second disc 7 is plugged into the positioning hole 9 in the ring gear 3, locking the ring gear 3 and the gear 21, and the swivel bridge plate 2 no longer rotates. Then the first bolt 10 is used to connect with the gear 21 to reinforce the position of the second disc 7.

[0051] When the height of the flip plate 11 needs to be adjusted, the second bolt 16 is turned to remove it, and then the two reciprocating screws 15 are turned in opposite directions, so that the reciprocating screws 15 drive the push plate 14 to slide in the first slide groove 13, so that the two push plates 14 move in the same direction, and the push plate 14 pushes the slope block 12 to push the flip plate 11, and then the flip plate 11 is pushed to the required height, and then the second bolt 16 is used to cooperate with the threaded hole 17 to fix the push plate 14 in position.

[0052] The height adjustment components on both sides can adjust the heights to the same level, or can be used to adjust different heights on both sides, thereby forming a certain angle between the flip plate 11 and the horizontal plane to meet different construction requirements.

[0053] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
