For the renewal and renovation of high-rise buildings in dense urban areas, higher requirements for green construction are imposed, and traditional extensive construction methods such as blasting demolition are no longer applicable.

[0003] In this regard, in the prior art, a method of using a lifting climbing frame and manual tools for layer-by-layer disassembly is adopted, and the demolition waste is sent out outside the floor in cooperation with a tower crane or a hoist. However, the current building construction or demolition machinery and equipment has a dedicated climbing or descending design for its power system, and is complex in structure and poor in versatility, and needs to be improved. Summary of the Invention

[0004] The present invention provides a lifting system of an automated building demolition machine and a method for using the same to solve the technical problems mentioned in the background art.

[0005] To achieve the above object, the present invention adopts the following technical solutions: A lifting system of an automated building demolition machine, comprising

The electric swivel arm upper bearing cross beam includes a horizontally arranged upper cross beam mounting seat and swivel arms respectively hinged at both ends of the upper cross beam mounting seat. An opening for the free passage of the steel strands is provided on the upper cross beam mounting seat;

[0012] The upper crossbeam mounting seat includes a top plate, a bottom plate, and a vertical plate connected between the top plate and the bottom plate. A driving rotating shaft is rotatably connected between the two ends of the top plate and the bottom plate. The top of the driving rotating shaft extends out of the top plate and is connected with a motor, and a rotating arm is fixedly connected to the driving rotating shaft;

[0020] Another object of the present invention is to provide a usage method for the lifting system of an automated building demolition machine, which has the effects of convenient operation and improved construction efficiency.

[0021] A usage method for the lifting system of an automated building demolition machine includes the following steps:

[0022] S1. The Nth floor is the floor to be built. Initial installation: The upper load-bearing crossbeam on the electric slewing arm is on the (N - 1)th floor, and the lower load-bearing crossbeam on the electric slewing arm is on the (N - 2)th floor.

[0023] S2. After the Nth floor is built, loosen all the lockings of the jacks. At this time, the lower load-bearing crossbeam on the electric slewing arm bears all the loads. Use the electric hoist installed on the upper fixed connecting beam to lift the jacks a short distance away from the (N - 1)th floor, and electrically control to retract the slewing arms at both ends of the upper load-bearing crossbeam on the electric slewing arm within the range of the operation hole.

[0024] S3. Use the electric hoist installed on the upper fixed connecting beam again to lift the jacks and the upper load-bearing crossbeam on the electric slewing arm until the upper load-bearing crossbeam on the electric slewing arm passes through the operation hole and reaches a short distance above the upper surface of the Nth floor.

[0025] S4. Extend the slewing arms at both ends of the upper load-bearing crossbeam on the electric slewing arm from the range of the operation hole, and operate the jacks to descend along the steel strands until the upper load-bearing crossbeam on the electric slewing arm reaches the upper surface of the Nth floor. At this time, the upper load-bearing crossbeam on the electric slewing arm bears all the loads. Then operate the jacks to perform a jacking motion, so that the steel strands drive the overall column assembly and the lower load-bearing crossbeam on the electric slewing arm to leave the upper surface of the (N - 2)th floor by a short distance, and retract the slewing arms at both ends of the lower load-bearing crossbeam on the electric slewing arm within the range of the operation hole.

[0026] S5. Then operate the jack-up jack for jacking-up movement until the load-bearing crossbeam under the electric slewing jib passes through the operation opening of the N-1st floor and reaches a short distance above the upper surface of the N-1st floor. At this time, the whole column assembly and the top truss system are also lifted by about the distance of one floor.

[0027] S6. Stretch out the slewing jibs at both ends of the load-bearing crossbeam under the electric slewing jib from the range of the operation opening, and operate the jack-up jack for lowering action until the load-bearing crossbeam under the electric slewing jib reaches the upper surface of the N-1st floor and then stop. At this time, the load-bearing crossbeam on the electric slewing jib and the load-bearing crossbeam under the electric slewing jib jointly bear the load. Wait until the construction of the N+1st floor is completed, and repeat in this way, rising layer by layer until the whole construction is completed.

[0028] In a preferred example, the present invention can be further configured as follows: It further includes the following steps:

[0029] S7. The Pth floor is the floor to be demolished. Initial installation: The load-bearing crossbeam on the electric slewing jib is on the Pth floor, and the load-bearing crossbeam under the electric slewing jib is on the (P-2)th floor.

[0030] S8. Loosen all the lockings of the jack-up jack. At this time, the load-bearing crossbeam under the electric slewing jib bears all the loads. Use the electric hoist installed on the upper fixed connecting beam to lift the jack-up jack a short distance away from the Pth floor. At this time, the Pth floor can be demolished.

[0031] S9. Use the electric hoist installed on the upper fixed connecting beam again to lower the jack-up jack and the load-bearing crossbeam on the electric slewing jib until the load-bearing crossbeam on the electric slewing jib reaches the upper surface of the floor of the (P-1)th floor. Then operate the jack-up jack for jacking-up movement so that the steel strand drives the whole column assembly and the load-bearing crossbeam under the electric slewing jib to leave the upper surface of the (P-2)th floor by a short distance. Retract the slewing jibs at both ends of the load-bearing crossbeam under the electric slewing jib within the range of the operation opening. At this time, the load-bearing crossbeam on the electric slewing jib bears all the loads.

[0032] S10. Operate the jack-up jack for lowering action until the load-bearing crossbeam under the electric slewing jib passes through the operation opening of the (P-2)th floor and reaches a short distance above the upper surface of the (P-3)th floor. At this time, the whole column assembly and the top truss system also descend by about the distance of one floor.

[0033] S11. Stretch out the slewing jibs at both ends of the load-bearing crossbeam under the electric slewing jib from the range of the operation opening, and operate the jack-up jack for lowering action until the load-bearing crossbeam under the electric slewing jib reaches the upper surface of the (P-3)th floor and then stop. At this time, the load-bearing crossbeam on the electric slewing jib and the load-bearing crossbeam under the electric slewing jib jointly bear the load. Repeat in this way, descending layer by layer until the whole construction is completed.

[0034] The beneficial effects of the present invention are reflected in: 1. By providing a lifting power system that can both rise (for building a building) and fall (for demolishing a building), the versatility of the entire system is good, facilitating its application to different usage requirements and working scenarios. At the same time, the entire system has a simple structure and stable operation, making it easy to be applied to building construction and demolition machinery and equipment;

[0035] 2. By adopting a lifting power system with convenient operation, the processes of the entire system rising (for building a building) and falling (for demolishing a building) are smoother and faster; thus achieving the effects of convenient operation and improved construction efficiency;

[0036] 3. In this application, 1) the shapes of the upper beam mounting seat and the swing arm are reasonably designed; 2) a motor is installed on the top plate to drive the rotating shaft in a linkage manner to control the rotation of the swing arm, enabling it to extend or retract from the range of the operation hole. At both ends of the operation hole, there are swing arm mating parts that turn towards the same side; 3) a contact sensor one and a contact sensor two are provided on the top plate of the upper beam mounting seat. On the swing arm, there are a contact slope seat one, a contact slope seat two, a stop seat plate one, and a stop seat plate two located between the top plate and the bottom plate. After the swing arm reaches the position of extending out of the operation hole range, it can be double-blocked and limited by the contact sensor one fitting on the contact slope one and the blocking bolt one fitting on the sensor mounting seat one, and the motor can be controlled to stop working through the contact sensor one. When the swing arm retracts into the operation hole, the swing arm rotates until the contact sensor two fits on the contact slope two and the blocking bolt two fits on the sensor mounting seat two for double-blocking and limiting, and the motor can be controlled to stop working through the contact sensor one; 4) the blocking bolt one and the blocking bolt two are respectively fixed by two nuts, and their positions can be adjusted front and back, facilitating the adjustment of whether the swing arm can smoothly extend into and retract from the operation hole range. Through the combination of the above four points, it is realized that the load-bearing beam on the electric swing arm can be electrically controlled whether it bears on the floor slab, eliminating the need for manual insertion and extraction control in the form of conventional sleeves and inserting rods in the past, with good automation and efficient task execution. This not only saves time and resources but also enables more work to be completed in a shorter time, reducing the pressure on workers and improving work efficiency.

[0037] Other features and advantages of the present invention will be described in the following description, and will become partially apparent from the description or be understood by implementing the present invention; the main purpose and other advantages of the present invention can be achieved and obtained through the solutions specifically pointed out in the description.

Detailed implementation manners

[0047] The following describes the technical solution of the present invention in detail through embodiments. The following embodiments are merely exemplary and can only be used to explain and illustrate the technical solution of the present invention, and cannot be construed as a limitation of the technical solution of the present invention.

[0048] Embodiment 1

[0049] A lifting system of an automated building demolition machine, comprising

[0050] A top truss system 1, located above the floor slab 8 to be built or the top floor slab 8 of the building;

[0051] The column assembly 2 is fixed below the top truss system 1 and vertically penetrates through the operation opening 7 on the floor slab 8. Both ends of the operation opening 7 have the swivel arm 901 mating parts that turn towards the same side.

[0052] The jack 4 is arranged inside the column assembly 2 and is used to control the synchronous lifting and lowering of the column assembly 2 and the top truss system 1.

[0053] The guide wheel set 5 is arranged on each floor slab 8 and is used to abut against the periphery of the column assembly 2 to limit the column assembly 2 during the lifting process, restrict the column assembly 2 to stably slide along the vertical direction, and provide stability during the process.

[0054] The steel strand 6 is vertically arranged inside the column assembly 2, passes through the inside of the jack 4, and is clamped and fixed by the upper and lower working parts of the jack 4. When the telescopic cylinder of the jack 4 works, it can apply a force to the column assembly 2 in the forward or reverse direction, so that the column assembly 2 can stably rise or fall.

[0055] The electric swivel arm upper bearing crossbeam 9 is fixed below the jack 4. The electric swivel arm upper bearing crossbeam 9 includes a horizontally arranged upper crossbeam mounting seat 902 and swivel arms 901 respectively hinged at both ends of the upper crossbeam mounting seat 902. An opening for the steel strand 6 to pass through freely is provided on the upper crossbeam mounting seat 902.

[0056] The upper crossbeam mounting seat 902 includes a top plate 903, a bottom plate 904, and a vertical plate 905 connected between the top plate 903 and the bottom plate 904. Both ends of the top plate 903 and the bottom plate 904 extend beyond the vertical plate 905, and a driving rotating shaft 906 is rotatably connected to the extended part. The top of the driving rotating shaft 906 extends out of the top plate 903 and is connected with a motor 907. A swivel arm is fixedly connected to the driving rotating shaft 906; the swivel arm 901 is used to press against the floor slab to achieve the support function.

[0057] The electric swivel arm lower bearing crossbeam 10 is fixed below the column assembly 2, and its structure is the same as that of the electric swivel arm upper bearing crossbeam.

[0058] In a preferred example, the present invention can be further configured as follows: a sensor mounting seat 908 is fixed at the end of the top plate 903, and a contact sensor 909 extending above the rotating arm 901 is fixed on the sensor mounting seat 908; a sensor mounting seat 910 is fixed on the side end of the top plate 903, and a contact sensor 911 extending above the rotating arm 901 is fixed on the sensor mounting seat 910; a contact slope seat 912, a contact slope seat 913 and a stop plate 914 located between the contact sensor 909 and the contact sensor 911 are fixed on the top of the rotating arm 901; a contact slope seat 912 is provided with a contact slope 915 at one end close to the contact sensor 909, a contact slope seat 913 is provided with a contact slope 916 at one end close to the contact sensor 911, and a stop plate 914 is provided horizontally on its upper edge. A blocking bolt 917 passes through the blocking seat plate, and the blocking bolt 917 is threadedly connected to the fixing nuts 918 located on both sides of the blocking seat. When the swing arm 901 rotates to the length direction of the upper beam mounting seat 902, the contact sensor 909 is attached to the contact slope 915 and the blocking bolt 917 is attached to the sensor mounting seat 908, and the swing arm 901 extends out of the range of the working hole 7; a blocking seat plate 919 is arranged between the top plate 903 and the bottom plate 904, and the blocking seat plate 919 is located on one side of the contact sensor 911. The blocking bolt 920 is threadedly arranged on the blocking seat plate 919. When the swing arm 901 rotates until the contact sensor 911 is attached to the contact slope 916 and the blocking bolt 920 is attached to the sensor mounting seat 910, the swing arm 901 is located in the working hole 7;

[0059] In a preferred example, the present invention can be further configured as follows: the column assembly 2 includes left and right columns 201, an upper fixed connecting beam 202, a lower fixed connecting beam 203 and a load-bearing connecting beam 204, the left and right columns 201 are vertically and arranged side by side, the upper fixed connecting beam 202 and the lower fixed connecting beam 203 are distributed up and down between the left and right columns 201, and are used to fix the two ends of the steel strand 6, the load-bearing connecting beam 204 is arranged below the lower fixed connecting beam 203, and is used to install and fix the lower load-bearing beam 10 of the electric jib, so as to increase the supporting stability of the structural strength of the lower load-bearing beam 10, and ensure the stability of the entire lifting system during operation.

[0060] In a preferred example, the present invention can be further configured as follows: an electric hoist 3 is provided in the column assembly 2, the electric hoist 3 is located above the lifting jack 4, and the hook of the electric hoist 3 can reach the upper side wall of the lifting jack 4 for lifting.

[0061] Therefore, when the entire lifting jack 4 needs to be raised or lowered by a distance of one floor, the electric hoist 3 is used to quickly move the lifting jack 4 along the steel strand 6, making the construction process more convenient and improving the construction efficiency.

[0062] In a preferred example, the present invention can be further configured as follows: the guide wheel set 5 includes a mounting frame 501 and rollers 502. The mounting frame 501 is used to be fixed on the floor slab 8. The rollers 502 are rotatably connected to the front end of the mounting frame 501 and are used to abut against the outer side wall of the column assembly 2.

[0063] Therefore, when lifting operations are required, the guide wheel set 5 at the outermost end can be disassembled, and then the disassembled guide wheel set 5 can be installed. During installation, only by using bolts or anchor bolts to fix the mounting frame 501 can the rapid fixation of the guide wheel set 5 be achieved, making the construction operation process easier and more convenient.

[0064] Embodiment 2

[0065] In a preferred example, the present invention can be further configured as follows: the mounting frame 501 includes a base 51, a sliding seat 52, a suspension 53, a screw rod 54 and a handle 55. The base 51 is used to be fixed on the floor slab 8. The sliding seat 52 is horizontally slidably connected to the base 51. The suspension 53 is arranged on the sliding seat 52 and is for installing and fixing the rollers 502. The screw rod 54 is horizontally threadedly connected to the rear of the base 51 and is rotatably connected to the tail end of the sliding seat 52. The handle 55 is arranged at the tail end of the screw rod 54.

[0066] In a preferred example, the present invention can be further configured as follows: the suspension 53 is rotatably connected to the sliding seat 52. An arc-shaped guide rod 56 is arranged on the sliding seat 52. A guide tube 57 slidably connected to the guide rod 56 is arranged at the tail end of the suspension 53. A screw 58 pressing against the upper end surface of the guide rod 56 is vertically threadedly connected to the guide tube 57.

[0067] When the guide wheel set 5 needs to be fixed, the base 51 can be arbitrarily fixed on the ground, and then the suspension 53 is controlled to rotate so that the suspension 53 and the rollers 502 face forward. Then, the handle 55 is controlled to drive the screw rod 54 to rotate, so that the sliding seat 52 horizontally slides forward. At this time, the sliding seat 52 drives the suspension 53 and the rollers 502 to move synchronously.

[0068] And until the rollers 502 abut against the outer wall of the column assembly 2, then the suspension 53 and the rollers 502 are controlled to rotate synchronously so that the rollers 502 can be pressed against the outer wall of the column assembly 2. Subsequently, the screw 58 is tightened to achieve the installation and fixation of the guide wheel set 5.

[0069] Therefore, by setting the guide wheel set 5 with adjustable front and rear positions and rotation angles, the guide wheel set 5 can be fixed arbitrarily during fixation, and the operation requirements of the guide wheel set 5 can be met through fine adjustment. There is no need for workers to lay out wires before installation, nor is precise installation required, making the installation process of the guide wheel set 5 more convenient and improving the construction efficiency at the same time.

[0070] Embodiment Three

[0071] A usage method of a lifting system of an automated building demolition machine includes the following steps:

[0072] Construction process:

[0074] S2. After the Nth floor is built, loosen all the locks of the jack 4. At this time, the load-bearing crossbeam under the electric swing arm bears all the loads. Use the electric hoist 3 installed on the upper fixed connecting beam 202 to lift the jack 4 a short distance away from the (N - 1)th floor, and electrically control to retract the swing arms 901 at both ends of the load-bearing crossbeam on the electric swing arm within the range of the operation opening 7.

Use the electric hoist 3 installed on the upper fixed connecting beam 202 again to lift the jack 4 and the load-bearing crossbeam on the electric swing arm until the load-bearing crossbeam on the electric swing arm passes through the operation opening 7 and reaches a short distance above the upper surface of the Nth floor.

[0076] S4. Extend the swing arms 901 at both ends of the load-bearing crossbeam on the electric swing arm from the range of the operation opening 7, and operate the jack 4 to descend along the steel strand 6 until the load-bearing crossbeam on the electric swing arm reaches the upper surface of the Nth floor. At this time, the load-bearing crossbeam on the electric swing arm bears all the loads. Then operate the jack 4 to perform a jacking movement, so that the steel strand 6 drives the entire column assembly 2 and the load-bearing crossbeam under the electric swing arm to leave the upper surface of the (N - 2)th floor by a short distance through the lower fixed connecting beam 203, and retract the swing arms 901 at both ends of the load-bearing crossbeam under the electric swing arm within the range of the operation opening 7.

[0077] S5. Then operate the jack 4 to perform a jacking movement until the load-bearing crossbeam under the electric swing arm passes through the operation opening 7 of the (N - 1)th floor and reaches a short distance above the upper surface of the (N - 1)th floor. At this time, the entire column assembly 2 and the top truss system 1 are also lifted by about the distance of one floor.

[0078] S6. Extend the booms 901 at both ends of the lower load-bearing crossbeam of the electric slewing jib from the range of the operation opening 7, and operate the jack 4 to perform a descending action until the lower load-bearing crossbeam of the electric slewing jib reaches the upper surface of the N-1 floor and then stop. At this time, the upper load-bearing crossbeam and the lower load-bearing crossbeam of the electric slewing jib jointly bear the load. Wait until the construction of the N+1 floor is completed, and repeat this process to rise layer by layer until the overall construction is completed;

[0079] Demolition process:

[0080] S7. The P floor is the floor to be demolished. Initial installation: The upper load-bearing crossbeam of the electric slewing jib is on the P floor, and the lower load-bearing crossbeam 10 of the electric slewing jib is on the P-2 floor;

[0081] S8. Loosen all the locks of the jack 4. At this time, the lower load-bearing crossbeam of the electric slewing jib bears all the loads. Use the electric hoist 3 installed on the upper fixed connecting beam 202 to lift the jack 4 a short distance away from the P floor. At this time, the P floor can be demolished;

[0082] S9. Once again, use the electric hoist 3 installed on the upper fixed connecting beam 202 to lower the jack 4 and the upper load-bearing crossbeam of the electric slewing jib until the upper load-bearing crossbeam of the electric slewing jib reaches the upper surface of the P-1 floor slab 8. Then operate the jack 4 to perform a jacking movement so that the steel strand 6 drives the whole column assembly 2 and the lower load-bearing crossbeam of the electric slewing jib to leave the upper surface of the P-2 floor by a short distance through the lower fixed connecting beam 203. Retract the booms 901 at both ends of the lower load-bearing crossbeam of the electric slewing jib within the range of the operation opening 7. At this time, the upper load-bearing crossbeam of the electric slewing jib bears all the loads;

[0083] S10. Operate the jack 4 to perform a descending action until the lower load-bearing crossbeam of the electric slewing jib passes through the operation opening 7 of the P-2 floor and reaches a short distance above the upper surface of the P-3 floor. At this time, the whole column assembly 2 and the top truss system 1 also descend by about the distance of one floor;

[0084] S11. Extend the booms 901 at both ends of the lower load-bearing crossbeam of the electric slewing jib from the range of the operation opening 7, and operate the jack 4 to perform a descending action until the lower load-bearing crossbeam of the electric slewing jib reaches the upper surface of the P-3 floor and then stop. At this time, the upper load-bearing crossbeam and the lower load-bearing crossbeam of the electric slewing jib jointly bear the load. Repeat this process to descend layer by layer until the overall construction is completed.

[0085] The present invention: 1. By setting up a lifting power system that can both rise (constructing a building) and descend (demolishing a building), the versatility of the whole system is good, which is convenient for application in different usage requirements and working scenarios. At the same time, the whole system has a simple structure and stable operation, and is convenient for application on building construction and demolition machinery and equipment;

[0086] 2. By adopting a lifting power system that is convenient to operate, the process of the entire system ascending (constructing a building) and descending (demolishing a building) becomes smoother and faster; thus achieving the effects of convenient operation and improved construction efficiency;

[0087] 3. In this application, 1) the shapes of the upper beam mounting seat 902 and the swing arm 901 are reasonably designed; 2) a motor 907 is installed on the top plate 903 to drive the rotating shaft 906 in a linked manner to control the rotation of the swing arm 901 so that it can extend or retract from the range of the operation opening 7. At both ends of the operation opening 7, there are swing arm 901 mating parts that turn towards the same side; 3) a contact sensor one 909 and a contact sensor two 911 are arranged on the top plate 903 of the upper beam mounting seat 902. On the swing arm 901, there are a contact slope seat one 912, a contact slope seat two 913, a retaining seat plate one 914, and a retaining seat plate two 919 located between the top plate 903 and the bottom plate 904. After the swing arm 901 reaches the position of extending out of the operation opening range, it can be double-blocked and limited by the contact sensor one 909 fitting on the contact slope one 915 and the blocking bolt one 917 fitting on the sensor mounting seat one 908, and the motor 907 can be controlled to stop working by the contact sensor one 909. When the swing arm 901 retracts into the range of the operation opening 7, the swing arm 901 rotates until the contact sensor two 911 fits on the contact slope two 916 and the blocking bolt two 920 fits on the sensor mounting seat two 910 for double-blocking and limiting, and the motor 907 can be controlled to stop working by the contact sensor one 909; 4) the blocking bolt one 917 and the blocking bolt two 920 are respectively fixed by two nuts, and the front and rear positions can be adjusted, which is convenient for adjusting whether the swing arm 901 can smoothly extend into and retract from the range of the operation opening 7. Through the combination and cooperation of the above four points, it is realized that the load-bearing beam 9 on the electric swing arm can be electrically controlled whether it bears on the floor slab 8, without the need for manual insertion and extraction control in the form of the previous casing and inserting rod, and has good automation work and can efficiently execute tasks. This not only saves time and resources, but also can complete more work in a shorter time, relieve the pressure on workers, and improve work efficiency.

[0088] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
