Description

Technical Field

[0001] This invention relates to a device for fixed-point lifting of materials and a passenger platform for multi-level installation in elevator shafts, belonging to the field of elevator installation and construction technology. Background Technology When installing equipment in elevator shafts, simple small winches, hoists, and hand-operated hoists are generally used as material lifting equipment. During installation, they are usually directly fixed to hooks at the top of the shaft. This presents two problems: First, elevator shafts generally need to be sealed at the top. If not, a lifting beam needs to be erected as a load-bearing point. Second, hooks capable of supporting sufficient weight need to be pre-installed at the top of the shaft. Third, the lifting point position cannot be changed and can only be fixed to the pre-installed hooks, making it difficult to meet the requirements of fixed-point lifting.

[0002] These three drawbacks are more pronounced when using elevator shafts for multi-level installations. During multi-level installations, the elevator shaft is unsealed and lacks pre-embedded hooks, requiring the use of temporary lifting beams. The installation of these beams is relatively complex, and a single beam is difficult to adapt to shafts of varying sizes. Furthermore, repositioning the lifting beams is challenging as the elevator moves between floors. The lifting point positions cannot be changed, necessitating manual lateral manipulation of the hoisted materials, increasing the difficulty of operation and adding a degree of risk.

[0003] For construction work involving personnel, scaffolding is generally used. Although there are scaffold-free construction techniques in the industry, for multi-level installations and work environments without suspension points at the top, such as the multi-functional shaft hoisting device disclosed in Chinese patent document CN104310239A, there are also defects in actual construction, such as the inability to raise the work platform, the lack of a personnel platform, or the conflict or interference between the lifting platform or scaffolding and the hoisting device. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a device for fixed-point lifting of materials and a passenger platform for multi-level installation in elevator shafts. The device is installed on the ground of any floor and on the hall door wall of the shaft. The device includes: A first power mechanism is fixed to the ground. The first power mechanism includes a rope-laying device and a rope reel driven by a first motor. A base frame is fixed to the ground and close to the wall of the hall door. The base frame is equipped with a telescopic beam structure that passes through the hall door and can extend into the shaft. One end of the telescopic beam structure that extends into the shaft is provided with a swing component. A bracket, installed above the base frame and connected to the hall door wall, the bracket having a crossbar, the crossbar being movably connected to the telescopic beam structure via a pull plate; and The manned platform is suspended below the first beam by a second and a third steel wire rope. The manned platform is equipped with a second power mechanism, which can drive the manned platform to perform lifting and lowering movements. The rope reel is wound with a first steel wire rope, which is led out from the rope reel and passes through the telescopic beam structure, the sway assembly, and is connected to the hook and the counterweight in sequence; the sway assembly can drive the first steel wire rope passing through the sway assembly to deflect horizontally.

[0005] It should be understood that the hall door is perpendicular to the ground and parallel to the direction of the shaft, and the hall door wall refers to the wall next to the hall door that is close to the ground. Therefore, the device of the present invention can be installed at the location of the hall door and the ground on any floor and can meet the usage requirements of multi-level installation. When used on each floor, the distance of the telescopic beam extending into the shaft can be adjusted to adapt to shafts of different sizes. At the same time, the telescopic beam structure, tie plate, and crossbar can form a stable triangular structure in the shaft, making the load-bearing capacity more stable when the telescopic beam structure is extended, meeting the load-bearing requirements, and avoiding the situation of breakage when using a single horizontal telescopic beam for load-bearing.

[0006] Furthermore, the first motor is connected to a reducer, and the rope winding device includes a lead screw, a slider mounted on the lead screw, and a first guide wheel connected to the slider. The lead screw drives the slider to perform reciprocating linear motion. After passing through the first guide wheel, the first wire rope enters the rope reel and is evenly wound under the action of the slider. The first motor can drive the first wire rope to lift and lower vertically. It should be understood that the first motor drives the first wire rope in two ways: winch type and climbing type.

[0007] In one embodiment of the present invention, the support is a structure formed by two right-angled triangular frames connected by crossbars, with the parallel right-angled sides of the two right-angled triangular frames respectively connected to the ground and the hall door wall; the pull plate is provided with a spiral fastener, which can lock the tension position of the pull plate for fixed-point positioning; the use of right-angled triangular frames can further form a stable support structure outside the shaft, preventing the ground-fixed base frame and power mechanism from tilting and losing fixation when the telescopic beam structure is under load, and the triangular structure inside the shaft formed by the telescopic beam structure, pull plate and crossbar makes the overall equipment more stable under force.

[0008] Furthermore, the telescopic beam structure includes a nested first beam and a second beam, both of which have a porous structure and are connected by one or more pins. The first beam is provided with a swaying component, and the second beam is mounted on the base frame.

[0009] Furthermore, the second beam is also provided with two second guide rope wheels that are close to each other. The gap between the two second guide rope wheels is smaller than the diameter of the first wire rope, which can prevent the first wire rope from detaching.

[0010] Furthermore, the oscillation assembly includes a rotating drum driven by a second motor and installed at one end of the telescopic beam structure, a third guide rope wheel located above the rotating drum and installed on the telescopic beam structure, and a polarization bracket connected to the rotating drum. The polarization bracket is provided with at least one fourth guide rope wheel, and the first wire rope passes through the third guide rope wheel and the fourth guide rope wheel in sequence and extends out from the fourth guide rope wheel to connect with the hook and the counterweight.

[0011] In one embodiment of the present invention, the second motor is connected to a first gear, and the rotating drum is provided with a second gear coaxial with the rotating drum. The second gear has a gear with a range of at least 4.7 rad that can mesh with the first gear. It should be understood that, driven by the second motor and transmitted by the first gear, the rotating drum can drive the polarization support to deflect within a range of 4.7 rad, thereby enabling hoisting operations on the three working faces in the shaft other than the hall door.

[0012] In one embodiment of the present invention, the polarization bracket has an L-shaped structure and two mutually perpendicular right-angled arms. One right-angled arm is parallel to the horizontal plane and located below the other right-angled arm. The two right-angled arms are respectively provided with fourth guide pulleys at different heights. After extending from the third guide pulley, the first wire rope first reaches vertically upwards and passes through the higher fourth guide pulley, and then obliquely downwards through the lower fourth guide pulley. It should be understood that the first wire rope, after extending from the third guide pulley, is concentric with the axis of the rotating drum. Therefore, when the rotating drum drives the oscillation assembly to rotate, the first wire rope will not twist itself. Compared with a structure where the first wire rope is not concentric with the axis of the rotating drum, the present invention provides a smoother and more stable deflection.

[0013] In one embodiment of the present invention, the edges of the third guide rope wheel and the fourth guide rope wheel are provided with stop pins to prevent the first wire rope from coming off and causing danger.

[0014] In one embodiment of the present invention, the bottom of the base frame is fitted and installed on the ground by means of a slot plate.

[0015] Furthermore, the manned platform is equipped with a fall protection device. The second power mechanism is suspended from the hanging ring by a second steel wire rope. The fall protection device can be a locking mechanism suspended from the hook by a third steel wire rope. The hanging ring and the hook are fixed to the first beam. The fall protection device can lock onto the third steel wire rope when the manned platform falls rapidly. The yaw component will drive the first steel wire rope to move in a position that does not interfere with the movement of the manned platform.

[0016] The beneficial effects of this invention are: This invention utilizes a power mechanism for drive, with a base frame and supports serving as auxiliary points for the ground and hall door walls. A swing component extending into the shaft is incorporated into the telescopic beam structure. This not only adapts to different multi-level installation requirements and shaft dimensions but also allows for precise, unobstructed control of the swing component to three working surfaces for fixed-point hoisting operations. Furthermore, by providing a non-interfering swing component and personnel platform at one end of the telescopic beam structure extending into the shaft, the invention fulfills the dual operational needs of carrying personnel and hoisting loads. Multiple guide wheels on the telescopic beam structure enhance traction stability and safety. The overall structure overcomes the limitations of traditional hoisting structures that can only be installed on the top of the car, offering wider applicability, more user-friendly operation, and precise positioning.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0029] The present invention provides a device for fixed-point lifting of materials and a passenger platform for elevator shaft multi-level installation. The device can be installed on the ground of any floor and on the hall door wall of the shaft. The device includes a first power mechanism 1, a base frame 2, a support 3 and a passenger platform 24.

[0030] Optionally, in one embodiment, the first power mechanism 1 is fixed to the ground 100 by a fixing frame 105. The first power mechanism includes a rope-laying device 104 driven by a first motor 101 and a rope reel 103. The first motor 101 is connected to a reducer 102. The rope-laying device 104 includes a lead screw 1041, a slider 1042 mounted on the lead screw, and a first guide wheel 1043 connected to the slider 1042. The lead screw 1041 drives the slider 1042 to perform reciprocating linear motion. The first wire rope 15 enters the rope reel after passing through the first guide wheel 1043 and is evenly wound under the action of the slider 1042. The first motor 101 can drive the first wire rope 15 to rise and fall vertically. Figure 1 , Figure 2 The first power mechanism 1 is a winch type. Figure 3 The first power mechanism 1 in the system is a climbing type.

[0031] Optionally, in one embodiment, the base frame 2 is fixed to the ground and close to the hall door wall 200. The base frame 2 is equipped with a telescopic beam structure that passes through the hall door and can extend into the shaft. The telescopic beam structure includes a nested first beam 4 and a second beam 201. Both the first beam 4 and the second beam 201 have a porous structure and are connected by a first pin 11 and a second pin 12. The first beam 4 is provided with a swaying component 7, and the second beam 201 is installed on the base frame 2. Two second guide rope wheels 502 close to each other are also installed on the second beam 201 through a fixing plate 501. The gap between the two second guide rope wheels 502 is smaller than the diameter of the first wire rope 15, which can prevent the first wire rope 15 from detaching.

[0032] Furthermore, the sway assembly 7 includes a rotating drum 702 driven by a second motor 13 and installed at one end of the telescopic beam structure, a third guide rope wheel 601 located above the rotating drum 702 and installed on the telescopic beam structure, and a polarization bracket connected to the rotating drum 702. The polarization bracket has an L-shaped structure and two mutually perpendicular right-angled arms, namely a horizontal right-angled arm 705 and a vertical right-angled arm 704. The horizontal right-angled arm 705 is parallel to the horizontal plane and located below the vertical right-angled arm 704. The vertical right-angled arm 704 and the horizontal right-angled arm 705 are respectively provided with a fourth guide rope wheel 703 (higher) and a fourth guide rope wheel 706 (lower) at different heights. After the first wire rope 15 extends from the third guide rope wheel 601, it first reaches vertically upward and passes through the fourth guide rope wheel 703, and then passes obliquely downward through the fourth guide rope wheel 706. The first wire rope 15 extends from the third guide pulley 601 and is concentric with the axis of the rotating drum 702. Therefore, when the rotating drum 702 drives the yaw assembly 7 to rotate, the first wire rope 15 will not twist itself. Compared with the structure in which the first wire rope 15 is not concentric with the axis of the rotating drum 702, the present invention will be smoother and more stable when deflecting. The edges of the third guide pulley 601, the fourth guide pulley 703, and the fourth guide pulley 706 are all provided with stop pins 707, which can prevent the first wire rope 15 from coming off and causing danger. The first wire rope 15 extends from the stop pins 707 and is connected to the hook 17 and the counterweight 16. The second motor 13 is connected to the first gear 14. The rotating drum is provided with a second gear 701 coaxial with the rotating drum. The second gear 701 has a gear of at least 4.7 rad that can mesh with the first gear 14. Driven by the second motor 13 and transmitted by the first gear 14, the rotating drum 702 can drive the polarization bracket to deflect within a range of 4.7 rad, thereby enabling hoisting operations on the three working faces in the shaft other than the hall door.

[0033] Optionally, in one embodiment, the bracket 3 is installed above the base frame 2 and connected to the hall door wall. The bracket 3 is a structure formed by two right-angled triangular frames connected by a crossbar 10. The parallel right-angled sides of the two right-angled triangular frames are connected to the ground and the hall door wall, respectively. The pull plate 8 is provided with a spiral fastener 9. The spiral fastener 9 has a forward thread 901 and a reverse thread 902, which are connected to the crossbar 10 and the pull plate 8, respectively, so as to lock the tension position of the pull plate 8 for fixed positioning. The use of right-angled triangular frames can further form a stable support structure outside the shaft, preventing the base frame and power mechanism fixed on the ground from tilting and being released when the telescopic beam structure is under load. The triangular structure inside the shaft formed by the telescopic beam structure, the pull plate 8, and the crossbar 10 makes the overall equipment more stable under force. The crossbar 10 is movably connected to the telescopic beam structure through the pull plate 8.

[0034] Optionally, in one embodiment, the manned platform 24 is suspended below the first beam 4 by a second steel wire rope 20 and a third steel wire rope 21. The manned platform 24 is provided with a second power mechanism 23, which can drive the manned platform 24 to perform lifting and lowering movements.

[0035] Optionally, the bottom of the base frame 2 is fitted and installed on the ground via a slot plate 301; the bottom of the bracket 3 is provided with an anchor bolt 300.

[0036] The first wire rope 15 is wound around the rope reel 103. After being led out from the rope reel 103, the first wire rope 15 passes through the telescopic beam structure, the sway assembly 7 and is connected to the hook 17 and the counterweight 16 in sequence.

[0037] When used on each floor, the distance of the telescopic beam structure extending into the shaft can be adjusted to adapt to shafts of different sizes. At the same time, the telescopic beam structure, tie plate 8, and crossbar 10 can form a stable triangular structure within the shaft, making the load-bearing capacity more stable when the telescopic beam structure is extended, meeting the load requirements, and avoiding the occurrence of breakage when using a single horizontal telescopic beam for load-bearing.

[0038] The second power mechanism 23 is suspended on the lifting ring 18 by the second steel wire rope 20. The fall protection device 22 is a locking mechanism suspended on the hook by the third steel wire rope 21. The lifting ring 18 and hook of the manned platform 24 are fixed to the end of the first beam 4 near the shaft. This arrangement ensures that the suspension point of the manned platform 24 will not change. The sway component 7 will drive the first steel wire rope 15 to rotate without interfering with the second power mechanism 23 driving the movement of the manned platform 24. The sway component 7 and the manned platform 24 can operate independently at the same time, thereby realizing the dual operation requirements of carrying people and lifting goods.

[0039] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Anyone skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the claims.
