Description

Technical Field

[0001] This invention relates to the field of construction auxiliary equipment technology, specifically to a hoisting device. Background Technology

[0002] Construction elevators utilize bridge-type drive units, including traction machines, controllers, and rope pulleys. During installation, these units are typically mounted on mounting frames. Generally, an installation platform is built at the top of the shaft, and the mounting frames are installed on this platform. However, this method requires manual handling of the platform and drive units when the shaft needs to be raised further for construction. This necessitates rebuilding and reinstalling the units, resulting in high labor intensity for workers and significantly reducing construction progress. Currently, some methods use mounting frames within the shaft to secure the units. When the shaft needs to be raised, the mounting frames are disassembled, and the units are manually moved and reinstalled at the required height. However, this method still requires manual handling, resulting in high labor intensity and reduced construction progress, failing to meet the requirements. Therefore, an improved solution is urgently needed. Summary of the Invention

[0030] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0031] like Figure 1-9 As shown, a hoisting device includes a hoisting platform 600 disposed within a shaft and a hoisting drive mechanism 700 for driving the hoisting platform 600 to move up and down within the shaft. The hoisting platform 600 is used to install a bridge car drive device 800 that drives the elevator car in the shaft to move up and down. When it is necessary to move the bridge car drive device 800 up and down within the shaft, the hoisting drive mechanism 700 drives the hoisting platform 600 to move the bridge car drive device 800 up and down within the shaft. When it reaches the desired position, the hoisting platform 600 and the bridge car drive device 800 are fixed within the shaft. When the bridge car drive device 800 and the elevator car are in working condition, the hoisting platform 600 is fixedly installed within the shaft. This invention can automatically lift and move the bridge car drive device 800 within the shaft. When it is not needed (when the elevator is working normally), the hoisting platform is used to fix the bridge car drive device 800 within the shaft, reducing the labor intensity of workers and greatly improving construction efficiency.

[0032] In this embodiment, the hoisting drive mechanism 700 includes a top beam 710 disposed within the shaft and a winch body 720 disposed on the hoisting platform 600. The top beam 710 is equipped with pulleys, and the hoisting rope of the winch body 720 passes over the pulleys and connects to the hoisting platform 600. When the bridge gearbox drive device 800 needs to be lifted, the top beam 710 is installed above the desired installation position, and the hoisting platform 600 is lifted to the desired position using the winch body 720, pulleys, and hoisting rope, thereby achieving automatic lifting and transport of the bridge gearbox drive device 800.

[0033] In this embodiment, the top beam 710 includes a top beam body 100, which has a crossbeam portion 110 and an inclined beam portion 120 that slopes upward from one end of the crossbeam portion 110. A connecting block 200 is provided at the other end of the crossbeam portion 110. In use, the inclined beam portion 120 abuts against the shaft wall, and the connecting block 200 is used to install the top beam body 100. The top beam body 100 of this top beam 710 has an inclined beam portion 120 at one end and a connecting block 200 at the other end. During installation, the connecting block 200 is fixedly installed, and the inclined beam portion 120 abuts against the shaft wall. During disassembly, only the connecting block 200 needs to be removed, and the top beam body 100 can be pulled upwards to disassemble the top beam 710. The 710 beam is not only easy to install and disassemble, but also has a stable and reliable structure after installation. Because the inclined beam 120 is inclined to contact the shaft wall, the heavier the load, the tighter the contact. It is not easy to loosen and greatly improves the safety of use.

[0034] In this embodiment, the connecting block 200 is provided with multiple rows of first adjustment holes 210 along the length direction of the crossbeam portion 110; the top beam 710 also includes an adjustment seat 400 and an installation plate 300 for installation at the shaft opening; the installation plate 300 is provided with multiple rows of second adjustment holes 310, the second adjustment holes 310 and the first adjustment holes 210 are connected by screws, and by adjusting the connection between the second adjustment holes 310 at different positions on the installation plate 300 and the first adjustment holes 210 at different positions on the connecting block 200, the installation length of the top beam body 100 can be changed, so that the top beam body 100 can adapt to the installation and use of shafts of different sizes; the top surface of the adjustment seat 400 is provided with a third adjustment hole 410, the third adjustment hole 410 and the first adjustment hole 210 are connected by screws. In use, the adjustment seat 400 is installed below the crossbeam 110. When the top beam body 100 is under load, the adjustment seat 400 abuts against the shaft wall, which serves to bear the load and position the beam against the shaft wall. The adjustment seat 400 can be adjusted and installed according to the length of the top beam body 100 and the first adjustment hole 210, which improves the stability and load-bearing performance of the structure.

[0035] In this embodiment, the adjusting seat 400 is provided with a horizontal plate 420, a vertical plate 430 connected to the horizontal plate 420, and multiple reinforcing plates 440 for connecting the horizontal plate 420 and the vertical plate 430. The third adjusting hole 410 is provided in the horizontal plate 420. In use, the connecting block 200 is installed with the horizontal plate 420, the vertical plate 430 abuts against the shaft wall, and the reinforcing plates 440 enhance the reliability of the adjusting seat 400 structure. The end of the inclined beam 120 is provided with an abutment plate 130. When the top beam body 100 is under load, the abutment plate 130 abuts against the shaft wall. The abutment plate 130 at the end of the inclined beam 120 abuts against the shaft wall, thereby increasing the load-bearing area with the shaft wall, making its installation reliable, and effectively protecting the top beam body 100 and the shaft wall.

[0036] In this embodiment, the hoisting platform 600 includes an inclined beam 60 and an installation platform 80 disposed on the inclined beam 60. One end of the inclined beam 60 is provided with an installation seat 03. The inclined beam 60 is inclinedly disposed in the shaft. The installation seat 03 at one end of the inclined beam 60 is used to connect with one side of the shaft. The other end of the inclined beam 60 abuts against the other side of the shaft. In this invention, the mounting platform 80 is used to install the bridge car drive device 800 that drives the lifting and lowering movement of the elevator car in the shaft. It includes a traction machine, controller, rope pulley, and other devices. When fixed, the mounting platform 80 is placed on the inclined beam 60. One end of the inclined beam 60 has a mounting seat 03 connected to one side of the shaft, and the other end of the inclined beam 60 abuts against the other side of the shaft. When disassembling, only the mounting seat 03 needs to be removed, and the inclined beam 60 can be pulled upwards to disassemble it. Its installation and disassembly are convenient, facilitating the lifting drive mechanism 700 to lift it. Since one end of the inclined beam 60 is inclined against the shaft wall, the heavier the load, the tighter the contact. After installation, the structure is stable and reliable, not easily loosened, greatly improving safety during use.

[0037] In this embodiment, the inclined beam 60 includes a first inclined arm 01 and a second inclined arm 02 connected to the first inclined arm 01. The mounting base 03 is disposed at the end of the second inclined arm 02. The first inclined arm 01 and the second inclined arm 02 are an adjustable connection structure along the length direction to adjust the length of the inclined beam 60. Specifically, the connection structure includes multiple adjustment holes 04 disposed in the first inclined arm 01 and the second inclined arm 02. The first inclined arm 01 and the second inclined arm 02 are connected by screws passing through the adjustment holes 04. In use, the connection position of the adjustment holes 04 of the first inclined arm 01 and the second inclined arm 02 is adjusted to the required length to adapt to different sizes of shafts. Two first inclined arms 01 and two inclined arms 02 are arranged side by side. One end of the first inclined arm 01 is sleeved inside the second inclined arm 02, making installation and adjustment convenient and the structure stable.

[0038] In this embodiment, one end of the first inclined arm 01 is provided with an abutment plate 06. The first inclined arm 01 abuts against the other side of the shaft using the abutment plate 06, which increases the contact area with the shaft wall, improves the load-bearing capacity, and effectively protects the shaft wall and the first inclined arm 01.

[0039] In this embodiment, the mounting base 03 includes a vertical seat 031 connected to the end of the second inclined arm 02, and a secondary mounting plate 032 mounted on the top surface of the vertical seat; it also includes a fixing plate 05 for installation at the shaft opening, and the secondary mounting plate 032 is connected to the fixing plate 05. The secondary mounting plate 032 and the fixing plate 05 are connected by screws to fix the inclined beam 60. When the inclined beam 60 is under load, the vertical seat 031 abuts against one side of the shaft wall, and the end of the first inclined arm 01 abuts against the other side of the shaft wall, thereby securing the inclined beam 60 within the shaft and improving the load-bearing capacity of the inclined beam 60.

[0040] In this embodiment, the installation platform 80 includes an upper platform 50 and a lower platform 70 connected to the second inclined arm 02. The upper platform 50 includes a first platform 501 connected to the second inclined arm 02 and a second platform 502 connected to the first platform 501.

Both the first platform 501 and the second platform 502 are provided with multiple connecting holes 504. The first platform 501 and the second platform 502 are connected by screws passing through the connecting holes 504.

[0041] In use, the bridge drive unit 800 can be installed on the upper platform 50 and the lower platform 70. The first platform 501 and the second platform 502 of the upper platform 50 can be adjusted in lateral length. When the length of the first inclined arm 01 and the second inclined arm 02 is adjusted according to the shaft size, the upper platform 50 can also be adjusted accordingly. The end of the second platform 502 is further fixed to the shaft wall with a fixing seat 503, which greatly improves the overall load-bearing capacity of the hoisting platform. When it needs to be moved, the fixing seat 503 and the shaft wall are loosened to facilitate the handling of the hoisting platform 600. One end of the first platform 501 is connected to the upper end of the second inclined arm 02, and the other end of the first platform 501 is connected to the lower end of the second inclined arm 02 with a connecting block 5011, which forms a triangular frame structure. The structure is stable and further improves the load-bearing capacity.

[0042] In this embodiment, the second platform 502 includes a first crossbeam 5021, a second crossbeam 5022 arranged parallel to the first crossbeam 5021, and a connecting beam 5023 connecting the first crossbeam 5021 and the second crossbeam 5022. The first crossbeam 5021 and the second crossbeam 5022 are both provided with the mounting holes 5024. The double crossbeam structure is simple and lightweight, and it is also convenient to install devices such as traction machines.

[0043] In this embodiment, the fixing seat 503 includes a vertical plate 5031 for fitting against the shaft wall, two side plates 5032 connected to both sides of the vertical plate 5031, and a horizontal plate 5033 connected to the middle of the two side plates 5032. The two side plates 5032 and the horizontal plate 5033 form an installation groove 5034. The end of the first crossbeam 5021 or the end of the second crossbeam 5022 extends into the installation groove 5034 and is connected to the horizontal plate 5033. The vertical plate 5031 is fitted against the shaft wall and is reliably installed. The installation groove 5034 limits the end of the first crossbeam 5021 or the end of the second crossbeam 5022, making it less prone to sliding and ensuring a reliable connection between it and the horizontal plate 5033.

[0044] In this embodiment, the lower platform 70 includes several connecting rods 701 connected to the second inclined arm 02, a hollow platform 702 connected to the bottom of the connecting rods 701, and a platform door 703 connected to the hollow platform 702. The connecting rods 701 serve to install and enclose the lower platform 70, facilitating the installation, housing, and protection of devices such as the traction machine and controller. Of course, the lower platform 70 can also be selected from other platform structures according to actual needs.

[0045] In this embodiment, the hoisting platform 600 is equipped with a slide rail 90, which allows the hoisting platform to be slidably installed in the shaft. When it is necessary to lift or move the hoisting platform 600 and the bridge box drive device 800 on it, the hoisting drive mechanism 700 is used to lift or lower the hoisting platform 600 as a whole, thereby reducing the labor intensity of manual handling and improving production efficiency.

[0046] In this embodiment, the hoisting platform 600 further includes a protective device for protecting the bridge gearbox drive unit 800. The protective device includes a first support 20, a second support 30, and a protective cover 40 mounted on the first support 20 and the second support 30. Specifically, the first support 20 is connected to the abutment plate 06, the second support 30 is connected to the first platform 501, and the protective cover 40 protects the bridge gearbox drive unit, improving safety performance. Specifically, the first support 20 and / or the second support 30 includes two height-adjustable columns 201 and a horizontal plate 202 connecting the two columns 201. The protective cover 40 rests on the horizontal plate 202. Specifically, the first support 20 and / or the second support 30 uses adjustable columns 201, which can adjust the height of the protective cover 40 and easily adjust the inclination of the protective cover 40, making it flexible and adaptable to different operating environments in the shaft.
