Description

Technical Field

[0001] This invention relates to the field of unloading device technology, and more specifically, to an unloading device that relies on jacks to transmit force. Background Technology

[0002] The massive columns and braces on the first floor of the super high-rise building are quite heavy. During installation, the support frame alone is insufficient to support the weight of the giant braces, so steel tie rods are needed to connect the columns and braces. After the concrete inside the giant braces is poured, the steel tie rods are removed. To prevent damage to the overall structure or specific areas from the large instantaneous impact force during unloading, a suitable unloading device needs to be designed to smoothly release the tension. Unloading typically uses a chain hoist, but chain hoists are difficult to operate and control at high altitudes, and have many limitations, making them unsuitable for unloading the steel tie rods.

[0003] Therefore, it is necessary to propose an unloading device that relies on jacks to transmit force, in order to at least partially solve the problems existing in the prior art. Summary of the Invention

[0004] The summary section introduces a series of simplified concepts, which will be further explained in detail in the detailed description section. The summary section of this invention is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0005] To at least partially solve the above problems, the present invention provides an unloading device that transmits force by a jack, comprising: an unloading device body, the unloading device body including two unloading units, the two unloading units being respectively disposed on both sides of a steel tie rod, each unloading unit including a jack, a cantilever plate, and a baffle, one end of the cantilever plate being connected to the steel tie rod, the baffle being disposed on the steel tie rod and close to one end of the cantilever plate, and the jack being disposed between the other end of the baffle and the cantilever plate.

[0006] According to an embodiment of the present invention, the unloading device that transmits force by jack has a cut on the steel tie rod, which divides the steel tie rod into a first segment and a second segment. One end of the cantilever plate is connected to the first segment, and the other end is located on the second segment. The baffle is disposed on the second segment.

[0007] According to an embodiment of the present invention, the unloading device that transmits force by jack has an I-shaped steel tie rod, and a plurality of first stiffening plates are disposed between the two side plates of the steel tie rod.

[0008] According to an embodiment of the present invention, in an unloading device that transmits force by a jack, a plurality of second stiffening plates are arranged on the side of the baffle away from the jack.

[0009] According to an embodiment of the present invention, the unloading device that transmits force by jacks has a plurality of third stiffening plates arranged on the outer side of one end of the cantilever plate.

[0010] According to an embodiment of the present invention, the unloading device that transmits force by jacks is further provided with an inner liner inside the cantilever plate, and the jack abuts against the side liner plate in the inner liner.

[0011] According to an embodiment of the present invention, the unloading device that transmits force by jacks further includes: two side pull plates, the two side pull plates being disposed on both sides of the steel tie rod, and the ends of the side pull plates being respectively connected to the other end of the cantilever plate.

[0012] According to an embodiment of the present invention, the unloading device that transmits force by a jack further includes an anti-movement module in the unloading unit. The anti-movement module is used to fix the jack. The anti-movement module includes a magnetic block and an upper moving block. The upper moving block is movably disposed on the magnetic block. The upper moving block is connected to a frame plate through multiple inner pull frames. The frame plate is provided with two side fixing frames and an intermediate frame. The intermediate frame is located between the two side fixing frames. The jack passes through the two side fixing frames and the intermediate frame.

[0013] According to an embodiment of the present invention, the unloading device that transmits force by a jack includes an outer U-shaped support block, an intermediate slider, a first inner support mechanism, and an outer pulling mechanism. The first inner support mechanism is disposed inside the upper moving block, the outer pulling mechanism is disposed on the outer wall of the upper moving block, the intermediate slider passes through the frame plate, the outer U-shaped support block is movably disposed on the intermediate slider, the outer U-shaped support block has a placement groove corresponding to the jack, and a locking mechanism is also disposed inside the outer U-shaped support block.

[0014] Compared with the prior art, the present invention has at least the following beneficial effects:

[0015] This invention provides a jack-based unloading device. The device includes a main body mounted on a steel tie rod. The main body comprises two unloading units, each including a jack, a cantilever plate, and a baffle. One end of the cantilever plate is connected to the steel tie rod, and the baffle is mounted on the steel tie rod near one end of the cantilever plate. The jack is installed between the baffle and the other end of the cantilever plate, ensuring that the resultant force of the unloading units remains along the centerline of the steel tie rod. The steel tie rod primarily bears the tension between the main column and the diagonal brace. During unloading, as the load-bearing capacity of the steel tie rod gradually decreases, the thrust of the jack on the cantilever plate increases. The tension borne by the steel tie rod is converted into pressure from the cantilever plate on the jack, thus maintaining the overall structural balance. When the steel tie rod is completely cut off, the main body of the unloading device completely replaces the steel tie rod, and then the thrust of the jack is gradually reduced to complete the unloading operation.

[0016] The unloading device that relies on jack force transmission according to the present invention, other advantages, objectives and features of the present invention will be partly apparent from the following description, and partly understood by those skilled in the art through study and practice of the present invention.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it based on the description.

[0028] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0029] like Figures 1-2As shown, the present invention provides an unloading device that transmits force via a jack, comprising: an unloading device body 100, which is mounted on a steel tie rod 200. Since the steel tie rod 200 is I-shaped, in order to achieve a more balanced unloading effect, the unloading device body 100 includes two unloading units 1, which are respectively mounted on both sides of the steel tie rod 200. This allows each unloading unit 1 to reasonably unload the steel tie rod 200 during dismantling. Specifically, the unloading unit 1 includes a jack 11, a cantilever plate 12, and a baffle 13. One end of the cantilever plate 12 is connected to... A steel tie rod 200 is connected, and a baffle 13 is installed on the steel tie rod 200 near one end of the cantilever plate 12. A jack 11 is installed between the baffle 13 and the other end of the cantilever plate 12, ensuring that the resultant force of the unloading unit 1 remains on the centerline of the steel tie rod 200. The steel tie rod 200 primarily bears the tension between the mega-column and the diagonal brace. During unloading (i.e., the cutting process of the steel tie rod 200), as the load-bearing capacity of the steel tie rod 200 gradually weakens, the thrust of the jack 11 on the cantilever plate 12 continuously increases. The tension borne by the steel tie rod 200 is transformed into pressure on the jack 11 from the cantilever plate 12, thus maintaining the overall structural balance. When the steel tie rod 200 is completely cut off, the unloading device body 100 completely replaces the steel tie rod 200, and then the thrust of the jack 11 is gradually reduced to complete the unloading operation.

[0030] Furthermore, cutting the steel tie rod 200 creates a cut 200a, dividing it into a first segment 201 and a second segment 202. To unload the tension from the steel tie rod 200, one end of the cantilever plate 12 is connected to the first segment 201, while the other end is located on one side of the second segment 202. A baffle 13 is installed on the second segment 202. With the jack 11 installed between the baffle 13 and the other end of the cantilever plate 12, support is provided between the first segment 201 and the second segment 202. The tension borne by the steel tie rod 200 is then converted into pressure from the cantilever plate 12 on the jack 11, thus maintaining the overall structural balance. After the steel tie rod 200 is completely cut, the unloading device body 100 completely replaces the steel tie rod 200, and then the thrust of the jack 11 is gradually reduced to complete the unloading operation.

[0031] Furthermore, the aforementioned steel tie rod 200 is I-shaped, and multiple first stiffening plates 204 can be installed between the two side plates 203 of the steel tie rod 200, thereby increasing the overall structural strength of the steel tie rod 200.

[0032] Furthermore, multiple second stiffening plates 131 are installed on the side of the baffle 13 away from the jack 11, and multiple third stiffening plates 121 are installed on the outer side of one end of the cantilever plate 12. The structural strength of the baffle 13 and the cantilever plate 12 is increased by the second stiffening plates 131 and the third stiffening plates 121.

[0033] Furthermore, an inner liner 14 is installed inside the cantilever plate 12, and the jack 11 abuts against the side liner plate 141 in the inner liner 14. The inner liner 14 increases the structural strength of the cantilever plate 12 from the inside, so as to facilitate a more reasonable unloading of the steel tie rod 200.

[0034] like Figure 3 As shown, the unloading unit 1 further includes two side pull plates 15, wherein the two side pull plates 15 are respectively installed on both sides of the steel tie rod 200, and the ends of the side pull plates 15 are respectively connected to the other end of the cantilever plate 12. Therefore, the balance of the cantilever plate 12 can be increased by the two side pull plates 15.

[0035] Exemplary anti-motion module

[0036] like Figures 4-5 As shown, in some embodiments of the present invention, an anti-movement module 2 is further added to the unloading unit 1. This anti-movement module 2 secures the jack 11, preventing it from accidentally falling off the steel tie rod 200. The anti-movement module 2 includes a magnetic block 3 and an upper moving block 4. Specifically, since two unloading units 1 are configured on the steel tie rod 200, one anti-movement module 2 can be installed on one side of the steel tie rod 200 via the magnetic block 3, and the other anti-movement module 2 can be installed on one side of the cantilever plate 12 via the magnetic block 3. The upper moving block 4 is movably mounted on the magnetic block 3. The upper moving block 4 is connected to a frame plate 40 via multiple inner brackets 41. Two side fixing brackets 5 and an intermediate bracket 6 are installed on the frame plate 40. The intermediate bracket 6 is located between the two side fixing brackets 5, allowing the jack 11 to be inserted between the two side fixing brackets 5 and the intermediate bracket 6, thereby achieving protective fixation of the jack 11 and preventing it from accidentally falling off the steel tie rod 200.

[0037] Furthermore, the aforementioned inner pull frame 41 includes an inner tension spring 411 and an inner pull rod 412. The inner pull rod 412 is connected to the bottom of the frame plate 40. Correspondingly, the upper moving block 4 has an inner pull groove 400 corresponding to the inner pull rod 412. Therefore, the inner tension spring 411 is sleeved on the inner pull rod 412 and connected to the frame plates 40 on both sides and the upper moving block 4, so that the frame plate 40 has a tendency to move into the upper moving block 4.

[0038] Exemplary magnetic block

[0039] like Figure 6As shown, further, some embodiments of the present invention provide a specific structure of the magnetic block 3 described above. The magnetic block 3 of this structure has an inner cavity 31, in which a second inner support mechanism 32 is installed. The second inner support mechanism 32 includes a bidirectional lead screw 321, two lead screw cylinders 322, two elastic hinges 323, an inner fixed plate 324, and a magnetic suction plate 325. Specifically, the bidirectional lead screw 321 passes through the inner cavity 31, with both ends of the bidirectional lead screw 321 extending out of the magnetic block 3. A T-shaped handle 326 is provided on the outer end. The two lead screw cylinders 322 are installed on the bidirectional lead screw 321 at intervals. The inner fixed plate 324 is installed at the bottom of the upper moving block 4. The magnetic suction plate 325 is slidably installed in the magnetic suction hole 301 of the magnetic block 3. The two elastic hinges 323 are respectively connected to the lead screw cylinders 322, and the open ends of the elastic hinges 323 are respectively connected to the inner fixed plate 324 and the magnetic suction plate 325. When the T-shaped handle 326 is rotated, the two lead screw cylinders 322 move closer to each other, causing the elastic hinge 323 to deform. The elastic hinge 323 then pushes the magnetic plate 325 located in the magnetic hole 301 outward, so that the magnetic plate 325 can be magnetically attracted to the steel tie rod 200, realizing the connection between the anti-movement module 2 and the steel tie rod 200, and also facilitating the subsequent separation of the two.

[0040] Exemplary side bracing

[0041] like Figures 6-7 As shown, further, some embodiments of the present invention provide a specific structure of the aforementioned side retainer 5. This side retainer 5 includes a side retaining ring 51, a side sliding plate 52, and a U-shaped torsion spring rod 53. Here, the side sliding plate 52 is mounted on the frame plate 40, while the U-shaped torsion spring rod 53 is mounted on the two outer walls of the upper moving block 4. The U-shaped torsion spring rod 53 is fastened to the frame plate 40 and located outside the side sliding plate 52. Multiple openings 521 are designed on the side sliding plate 52, allowing the side retaining ring 51 to be slidably mounted on it. The U-shaped torsion spring rod 53 prevents the side retaining ring 51 from detaching from the side sliding plate 52. The side retaining ring 51 has an inner liner 51 inside. The jack 11 can be further secured by the inner liner ring 510. An inner groove 511 is provided within the side fixing ring 51, in which a first clamping member 512 and a second clamping member 513 are installed. A first retaining spring 514 is installed on the first clamping member 512, and a second retaining spring 515 is installed within the second clamping member 513. The first clamping member 512 abuts against the second retaining spring 515, causing the second clamping member 513 to pass through the side fixing ring 51 and the inner liner ring 510 to abut against the jack 11. The first clamping member 512 extends through the side fixing ring 51 into the opening 521, thus allowing the side fixing ring 51 to be installed onto the side slide plate 52. The side fixing brackets 5 with the above structure can secure the jack 11, and the left and right spacing between the two side fixing brackets 5 can be adjusted according to the model of the jack 11.

[0042] Exemplary intermediate frame

[0043] Furthermore, some embodiments of the present invention provide a specific structure for the intermediate frame 6 described above. Here, the intermediate frame 6 of this structure includes an outer U-shaped support block 61, an intermediate slider 62, a first inner support mechanism 63, and an outer pulling mechanism 64. The first inner support mechanism 63 is installed inside the upper movable block 4, and the outer pulling mechanism 64 is installed on the outer wall of the upper movable block 4. The outer pulling mechanism 64 is movably connected to the first inner support mechanism 63, and the first inner support mechanism 63 is driven to move by the outer pulling mechanism 64.

[0044] The aforementioned intermediate slider 62 is mounted on the frame plate 40. Furthermore, the outer U-shaped support block 61 is movably mounted on the intermediate slider 62. Correspondingly, a placement slot 611 is provided on the outer U-shaped support block 61, so that the jack 11 can be placed in the two placement slots 611. In addition, a locking mechanism 65 is installed inside the outer U-shaped support block 61. The jack 11 can be fixed by the locking mechanism 65, thereby increasing the stability of the anti-movement module 2 for the jack 11.

[0045] Furthermore, the outer U-shaped support block 61 has a locking rod 641, which passes through the outer U-shaped support block 61 and is screwed to the middle slider 62 at the bottom. The middle slider 62 also has a support rod 620 corresponding to the outer U-shaped support block 61.

[0046] Exemplary first internal support mechanism

[0047] like Figure 8As shown, further, some embodiments of the present invention provide a specific structure of the first inner support mechanism 63 described above. The first inner support mechanism 63 of this structure includes a plurality of eccentric support blocks 631, which are rotatably installed between the upper moving block 4 and the intermediate slider 62 and can support the frame plate 40. The outer pulling mechanism 64 includes an intermediate pull rod 641 and an outer rotating rod 642. Here, the intermediate pull rod 641 passes through the upper moving block 4 and is rotatably connected to the plurality of eccentric support blocks 631. One end of the intermediate pull rod 641 is slidably connected in the inner sliding groove 645 of the outer rotating rod 642. One end of the outer rotating rod 642 is rotatably installed on the outer wall of the upper moving block 4, and the other end is connected to the outer locking block 42 of the upper moving block 4 through an L-shaped locking rod 643 and a locking spring 644. Therefore, when the L-shaped locking rod 643 is pulled, and the L-shaped locking rod 643 compresses the locking spring 644, the other end of the outer rotating rod 642 separates from the outer locking block 42. Then the outer rotating rod 642 can be rotated, and one end of the middle pull rod 641 slides along the inner sliding groove 645 while being pulled out from the upper moving block 4. It can be understood that when the middle pull rod 641 moves outward, it drives the eccentric support block 631 to rotate, and the eccentric support block 631 rotates from one side of the frame plate 40 to the inside of the middle slider 62. Under the action of the inner pull frame 41, the frame plate 40 moves relative to the middle slider 62, and the side fixing frame 5 on the frame plate 40 has a tendency to pull the jack 11, while the middle frame 6 has a tendency to push the jack 11. This fixes the anti-movement module 2 to the jack 11, preventing it from accidentally falling off the steel pull rod 200.

[0048] Exemplary locking mechanism

[0049] like Figure 9 As shown, some embodiments of the present invention provide a specific structure of the locking mechanism 65 described above. This locking mechanism 65 includes an inner locking rod 651, a locking cap 652, and an inner spring 653. The inner locking rod 651 passes through the outer U-shaped support block 61. Two eccentric rods 654 are mounted on the inner locking rod 651. The outer U-shaped support block 61 has guide balls 655 corresponding to the eccentric rods 654. The guide balls 655 can protrude into the placement groove 611, thus contacting the jack 11 and facilitating left and right movement of the jack 11. Move to the right to be in the appropriate position. Install the inner spring 653 in the inner spring groove 613 of the outer U-shaped support block 61. The inner locking rod 651 passes through the inner spring 653 and is connected to the lock cap body 652. So when the lock cap body 652 is rotated, the eccentric rod 654 can rotate to abut against the guide ball 655 and lock it from the inside. In this way, the jack 11 cannot move in the placement groove 611. The inner spring 653 abuts against the lock cap body 652, so that the lock cap body 652 is tightly attached to the inner spring groove 613, preventing the inner locking rod 651 from rotating and releasing the guide ball 655.
