Description

Technical Field

[0001] The invention belongs to the technical field of building construction, and relates to a mechanical hydraulic device for automatic lifting, assembly and disassembly of a tower standard section. Background Art

[0002] With the rise of intelligent construction, robotic construction has become a research hotspot. Traditionally, scaffolding-based construction methods suffer from low efficiency and high energy consumption. While existing "building robots" achieve automated construction, they require a building of a certain height to operate, making them unsuitable for automated, unmanned construction of low-rise, large buildings. A ground-based construction system with automated lifting capabilities could fill this gap.

[0003] For automatic lifting, a technical solution similar to the standard section of a tower crane can be adopted. The lifting and lowering of the construction system can be achieved through the process of lifting, connecting, disassembling and lowering the standard section.

[0004] CN103738891B proposes a standard section lifting device and a construction method for continuously and automatically lifting standard sections. This device enables a small-stroke lifting jack to lift taller standard sections, and the standard sections are lifted from the bottom up. However, in this device, the two standard sections are still connected by bolts, requiring human intervention, making it impossible to fully automate the lifting process and resulting in low efficiency. Furthermore, during the force conversion process, the weight of the standard section is borne by the lugs on it, which may cause shear damage to the lugs and render the device ineffective.

[0005] CN114963586A proposes a standard joint that is easy to assemble and allows for quick connection and disassembly. The device uses the abutment of an insert rod to drive the rotation of a grabbing rod, thereby grabbing or releasing a retaining ring, which is a fixed component. When the standard joint is connected, the device achieves axial locking of the standard joints due to the action of a return spring, but does not effectively lock the connection radially. This may cause radial movement during use, affecting the structural stability.

[0006] CN114263665A proposes a standard section connection structure that enables quick connection between standard sections. The device uses a rack and pinion pair to drive a reinforcing rod into a slot for guidance and positioning, and is connected by fasteners on a U-shaped plate. However, the fixed connection still uses bolts, requiring manual intervention and a low degree of automation. Summary of the Invention

When the electromagnet 325 is energized, the magnetic force of the electromagnet 325 causes the two auxiliary sliders 324 to move toward each other, overcoming the force of the third resetting elastic member 323.

[0094] Please see again Figure 1As shown in the figures, the force conversion support mechanism 2 includes a conversion jack 21 installed on the top of the lifting frame, and a pair of conversion beams 22 slidingly matched with the lifting frame. The conversion jack 21 is connected to the conversion beam 22, and drives the conversion beam 22 to slide on the lifting frame and relatively approach or move away. When the standard section mechanism 5 is driven by the jacking platform 6 to a position higher than the conversion beam 22, the conversion jack 21 is relatively close to and clamps the standard section mechanism 5, thereby realizing the force conversion of supporting the standard section mechanism 5. In order to facilitate the support of the standard section mechanism 5, semicircular grooves 221 are provided on the conversion beam 22 corresponding to the number of standard section columns 511 of the contactable standard section mechanism 5. In this way, by adjusting the position of the conversion beam 22, some of the standard section columns 511 on the standard section mechanism 5 can be embedded in the semicircular grooves 221. At this time, the conversion beam 22 can clamp the spring-loaded mounting seat 531 and the like located on the standard section column 511. At the same time, the part of the conversion beam 22 located between the two semicircular grooves 221 forms a middle support platform 222 that can support the top beam or bottom beam of the standard section mechanism 5. The middle support platform 222 can protrude laterally to better extend under the top beam of the standard section mechanism 5, etc., to facilitate the force system conversion support.

[0095] Please see again Figure 15 As shown in the figures, the feed platform 4 includes a feed base, a feed slide 41 mounted on the feed base for sliding along the horizontal direction, and a feed jack 42 mounted on the feed base and connected to the feed slide 41. The feed slide 41 is also provided with several positioning bosses 43 for positioning and placing the standard section mechanism 5.

[0096] The working process of the mechanical hydraulic device of this embodiment is as follows. Figures 21 to 28 :

[0097] A. Install the lifting frame 1:

[0098] The lifting frame 1 is assembled and placed on the existing load-bearing structure.

[0099] B. First feed

[0100] like Figure 21 As shown, the standard section mechanism 5 is placed on the feed platform 4, and the positioning is achieved by cooperating with the four positioning bosses 43 on the feed platform 4 and the bottom grooves of the standard section columns 511 on the standard section mechanism 5, and then the feed platform 4 is moved to the inside of the lifting frame 1 through the retraction action of the feed jack 42.

[0101] C. First jacking:

[0102] like Figure 22 、 23As shown, the lifting jack 61 extends the cylinder to lift the lifting platform 6, and the guide boss 63 of the lifting platform 6 contacts and cooperates with the bottom grooves of the two standard section columns 511 of the standard section mechanism 5, lifting the standard section mechanism 5 on the feed platform 4 and moving it upward. At the same time, the electromagnet 325 in the auxiliary connecting member 32 works to close the auxiliary claw 322, and the first boss of the hook rod in the hook connector 52 at the bottom of the standard section mechanism 5 touches the auxiliary claw 322. As the standard section mechanism 5 rises, the first boss of the hook rod drives the hook rod 523 to be pressed down until the second boss of the hook rod is pressed into the second boss 5322 of the spring buckle on the lifting platform 6 and is in an inverted connection. The connection between the standard section and the lifting platform is completed (this process can be described in detail in step G). After that, the auxiliary jack 34 works to lift the auxiliary platform 3 so that it moves with the standard section mechanism 5 (as a guide) until the bottom of the snap-on mounting seat 531 of the standard section mechanism 5 is 10±5 mm higher than the semicircular groove 221 of the conversion beam 22, and the electromagnet 325 is de-energized.

[0103] D. First lifting motion force system conversion

[0104] like Figure 24 As shown, the transfer jack 21 extends the cylinder to adjust the position of the transfer beam 22 so that the transfer beam 22 is relatively close to each other, and its semicircular groove 221 is below the snap-on mounting seat 531. At this time, the middle support platform 222 also reaches below the top crossbeam of the standard section column. Then the auxiliary jack 34 moves to align the auxiliary claw 322 with the wedge-shaped platform on the lifting platform 6. At this time, the electromagnet 325 is energized, and the standard section mechanism 5 is disconnected from the lifting platform (this process can be described in detail with reference to step M); at the same time, the lifting jack 61 retracts the cylinder, thereby achieving a force system conversion, realizing that the gravity of the standard section mechanism 5 is transferred from the main column and the lifting jack 61 to the transfer beam 22. At this time, the bottom of the snap-on mounting seat 531 is supported on the semicircular groove 221, and the top crossbeam of the standard section is supported on the middle support platform 222.

[0105] E. Second feed

[0106] like Figure 25 As shown, the standard section mechanism 5 is placed on the feed platform 4, and positioning is achieved by cooperating with the four bosses on the feed platform 4 and the standard section columns 511, and then the feed platform 4 is moved to the inside of the starting frame by the retraction action of the feed jack 42.

[0107] F. Second jacking

[0108] like Figure 26 As shown, it is the same as step C, but this time the first and second standard sections are matched and connected.

[0109] G. Automatic connection of standard sections

[0110] like Figure 16 、 17 As shown in Figures 19 and 26, the electromagnet 325 is energized to close the auxiliary claw 322. As the bottom standard section is lifted, the auxiliary claw 322 contacts the first boss of the hook rod on the standard section mechanism 5 of the first section, driving the hook rod 523 to move downward, so that the wedge-shaped surface of the second boss of the hook rod contacts the second boss 5322 (i.e., the snap-on projection) of the snap-on mounting member of the other standard section, and presses the snap-on member 532 in and retracts it until the top of the second boss of the hook rod and the bottom of the second boss 5322 are coplanar. At this time, the snap-on member 532 is ejected under the action of the second reset elastic member 533, and the hook rod 523 hooks the snap-on member 532. Then, the electromagnet 325 is de-energized, and the auxiliary claw 322 is reset under the action of the third reset elastic member 323 to prevent it from interfering with the snap-on member 532, thus completing the automatic connection of the standard sections. At this time, due to the downward pulling force, the outer conical ring 521 presses against the inner conical ring 522, and the inner conical ring 522 hugs the standard section column 511 of the first section standard section mechanism 5, so that the standard section column 511 of the first section and the top boss 512 on the column of the second section standard section are tightly hugged, thereby reducing the fitting clearance between the two. It should be noted that due to space limitations, only the outer four hook rods on each column are connected, and the remaining two hook rods are always in a retracted state.

[0111] H. Second lifting motion force system conversion

[0112] like Figure 26 As shown, same as step D;

[0113] I. Repeat steps E to H above to achieve the automatic jacking operation of n standard sections of steel frames; n is any integer between 2 and 20.

[0114] J. Conversion beam 22-underframe force system conversion

[0115] like Figure 15 、 28As shown, when the standard section mechanism 5 reaches the specified height, the standard section as a whole needs to be moved from the conversion beam 22 to the standard section chassis 7. The lifting jack 61 extends the cylinder to lift the lifting platform 6, and the guide boss 63 of the lifting platform 6 contacts and cooperates with the standard section column 511 to lift the standard section on the conversion beam 22 and move it upward until the bottom crossbeam of the standard section is 30±10mm higher than the top of the conversion beam 22. Then the conversion jack 21 is controlled to retract the cylinder to retract the conversion beam 22, and then the lifting jack 61 is controlled to retract the cylinder to lower the lifting platform 6 to the standard section chassis 7; thereby achieving force system conversion, realizing that the gravity of the standard section is first converted from the conversion beam 22 to the main column and the lifting jack 61, and then converted to the standard section chassis 7. After that, the auxiliary jack 34 moves so that the bottom of the auxiliary claw 322 is slightly higher than the top of the first boss of the hook rod on the bottom standard section mechanism 5, and then the electromagnet 325 is energized, the auxiliary claw 322 is retracted, and the auxiliary jack 34 shrinks the cylinder, so that the auxiliary claw 322 touches and presses down the first boss of the hook rod, thereby completing the connection between the bottom standard section mechanism 5 and the standard section base frame 7.

[0116] K. Lowering and disassembly

[0117] The auxiliary jack 34 is controlled to move so that the auxiliary claw 322 is flush with the wedge-shaped boss 5323 of the snap-fastener 532 on the standard section chassis 7. The electromagnet 325 is then energized to retract the auxiliary claw 322, thereby pressing the snap-fastener 532 inward and releasing the snap-fastener rod 523. At this point, the bottom standard section mechanism 5 is disconnected from the standard section chassis 7 (this process is described in detail in step M). The lifting jack 61 is then controlled to extend until the bottom of the snap-fastener mounting seat 531 of the second standard section is 10±5 mm above the semicircular groove 221 of the transfer beam 22. The electromagnet 325 is then de-energized.

[0118] L. Conversion of descending motion system

[0119] like Figure 26 As shown, the transfer jack 21 extends the cylinder, adjusts the position of the transfer beam 22, and makes the transfer beam 22 relatively close together, and its semicircular groove 221 reaches below the spring-loaded mounting seat 531 of the second-last standard section. At this time, the middle support platform 222 also reaches below the top crossbeam of the standard section column. Then the jacking jack 61 is controlled to retract the cylinder. At the same time, the connection between the two standard section mechanisms 5 at the bottom is disconnected by controlling the auxiliary platform 3 (this process is described in detail with reference to M), thereby achieving a force system conversion, realizing that the gravity of the second-last standard section mechanism 5 is transferred from the main column and the jacking jack 61 to the transfer beam 22. At the same time, the first-last section is separated from the second-last standard section mechanism 5. The first-last standard section mechanism 5 is still connected to the jacking platform 6 through the hook connector 52 and the spring-loaded connector 53, and moves with the jacking platform 6.

[0120] M. Automatic disassembly of standard section

[0121] like Figure 16 、 19 20. The control electromagnet 325 is energized, closing the auxiliary claw 322. The lifting jack 61 is then controlled to retract, lowering the standard section mechanism 5 (moving relative to the auxiliary platform 3). As the standard section mechanism 5 descends, the auxiliary claw 322 contacts the wedge-shaped boss 5323 of the snap member 532, pressing the snap member 532 inward. At this point, the second boss of the hook rod no longer contacts the second boss 5322 of the snap member. The hook rod is retracted under the action of the first return spring 524.

[0122] N. Standard section exit

[0123] The automatic control system is used to control the retraction of the feed jack 42 so that the feed platform 4 enters the lifting frame 1, and the lifting jack 61 is controlled to continue to retract until the standard section mechanism 5 falls on the feed platform 4, and then the auxiliary platform 3 is controlled to disconnect the standard section from the lifting platform, and then the feed jack 42 is controlled to extend the cylinder to withdraw the standard section from the lifting frame 1.

[0124] O. Repeat steps K to N above to achieve the automatic jacking operation of n standard sections of steel frame; n is the number of standard sections installed previously.
