Description

Technical Field

[0001] This invention relates to a lifting device for working at heights, and more particularly to a hoisting machine for suspended platforms at heights. Background Technology

[0002] A suspended platform for high-altitude operations is a new type of machinery that can replace traditional scaffolding, reduce labor intensity, improve work efficiency, and is reusable. The suspended platform relies primarily on a hoist to wind up and down steel wire ropes for ascent and descent. Therefore, the hoist is one of the key pieces of equipment for a suspended platform, and its performance directly affects the safety and work efficiency of the platform.

[0003] Existing suspended platform hoists are mainly classified into two types based on the wire rope winding method: "α" type hoists and "S" type hoists. Among them, the "α" type hoist is further divided into double-pressure wheel hoists, snail-type hoists, and wheel-type hoists based on the wire rope pressing structure. Currently, the double-pressure wheel hoist has the largest market share and is the most widely used (e.g., Figure 1 As shown). Snail-type elevator (such as...) Figure 3 (As shown) It was once popular, but due to its large weight and bulkiness, it is gradually being phased out of the market. Wheel-type elevators (such as...) Figure 6 The product shown is a new type of anti-rope-jamming hoist. This product is already on the market. For a detailed description of the wheel-type hoist, please refer to the utility model patent (patent number: ZL2022211516358).

[0004] Suspended platform hoists all consist of three parts: a drive motor, a reduction gear mechanism, and a rope pressing mechanism. The structures of these three types of hoists differ, each with its own advantages and disadvantages, which are analyzed below.

[0005] The drive motor of the double-pressure roller hoist is a squirrel-cage three-phase asynchronous motor (1), the reduction mechanism is a worm gear transmission reduction mechanism (3), and the rope pressing mechanism is a double-pressure roller rope pressing mechanism (2). Figure 2 As shown. The advantages are: due to historical reasons, it has a large market share; parts are of universal size; parts are inexpensive due to numerous suppliers; and it weighs only 40-48 kg, making it relatively lightweight and easy to handle and install. The disadvantages are: the rectifier block is prone to burning out; the motor dust cap is easily crushed; the hoist base leaks oil; the worm gear is prone to tooth breakage during worm gear transmission; and the biggest problem is rope jamming at the hoist base, which poses a significant safety hazard.

[0006] The drive motor of the snail-type hoist adopts a three-phase disc brake asynchronous motor (9), abbreviated as disc motor, the reduction mechanism adopts a cycloidal pinwheel reduction transmission mechanism (8), and the rope pressing mechanism adopts a five-pressure wheel rope pressing mechanism (7). Figure 4 , Figure 5 As shown. The advantages are: the drive motor uses a disc motor, which is small in size, saves space, has good heat dissipation, requires no fan, and the disc motor brake does not use a rectifier, eliminating the risk of rectifier burnout; the reduction mechanism uses a cycloidal pinwheel reduction mechanism, which has high transmission efficiency, a compact structure, small size, smooth operation, low noise, strong overload capacity, durability, long service life, and convenient maintenance, using grease lubrication to reduce oil leakage; the disadvantages are: the machine weighs 64 kg, is bulky, inconvenient to transport and install, the installation dimensions for mounting it on the basket are not compatible with other hoists, and the snail-type hoist also occasionally experiences rope jamming.

[0007] The drive motor and reduction mechanism of the wheel-type hoist are the same as those of the double-pressure-wheel hoist. The drive motor is a squirrel-cage three-phase asynchronous motor (12), and the reduction mechanism is a worm gear transmission reduction mechanism (14). The only difference is the rope pressing mechanism; the wheel-type hoist uses a wheel-type rope pressing mechanism (13). Figure 7 As shown. The advantages are that, due to the use of a wheel-type rope pressing mechanism, the probability of the hoist getting stuck is greatly reduced, the maintenance rate is greatly reduced, safety is improved, and work efficiency is improved; the disadvantages are that the rectifier block is prone to burning out, the motor dust cap is prone to being crushed, the hoist base leaks oil, and the worm gear is prone to tooth breakage during worm gear transmission.

[0008] The performance of the suspended platform hoist directly affects the safety and work efficiency of suspended platforms used for high-altitude operations. Analyzing both safety and efficiency, none of the three types of suspended platform hoists mentioned above can be considered perfect. Therefore, it is necessary to integrate their advantages and mitigate their disadvantages to design and develop a new type of suspended platform hoist that meets the requirements for both safety and work efficiency in suspended platforms used for high-altitude operations. Summary of the Invention

[0009] The technical problem to be solved by this invention:

[0010] The suspended platform hoist is one of the key pieces of equipment for high-altitude operations, and its performance directly affects the safety and efficiency of the suspended platform. Existing suspended platform hoists have many drawbacks, such as rope jamming at the hoist base; easy burning of the rectifier block; easy denting of the motor dust cap; oil leakage at the hoist base; easy tooth breakage of the worm gear during worm gear transmission; heavy weight, making handling and installation inconvenient; and incompatibility of installation dimensions between the hoist and the suspended platform basket. Due to these shortcomings, falls from height during suspended platform exterior wall construction are frequent, and the increased manpower and material costs during the use and maintenance of the suspended platform hoist are also a significant expense. Therefore, it is necessary to integrate the advantages of various hoists, avoid their disadvantages, and design and develop a new type of suspended platform hoist to improve its safety and efficiency.

[0011] The present invention adopts the following technical solution:

[0012] All suspended platform hoists consist of three structural parts: a drive motor, a reduction gear mechanism, and a rope pressing mechanism. Each type of hoist has a different structure, with its own advantages and disadvantages. Based on theoretical analysis and practical experience, it can be seen that the snail-type hoist, using a disc motor, has advantages such as small size, space saving, good heat dissipation, no need for a fan, and the disc motor brake does not use a rectifier, eliminating the risk of rectifier burnout. Its stamped casing is also sturdy and durable. The cycloidal pinwheel reduction mechanism used in the snail-type hoist has advantages such as high transmission efficiency, compact structure, small size, smooth operation, low noise, strong overload capacity, long service life, convenient maintenance, and grease lubrication, reducing oil leakage. The wheel-type hoist uses a wheel-type rope pressing mechanism, which has the advantage of preventing rope jamming.

[0013] The technical solution of this invention is to integrate the above-mentioned structural design with excellent performance into a new type of suspended platform hoist. Specifically, the suspended platform hoist of this invention uses a disc motor as the drive motor, a cycloidal pinwheel reduction mechanism as the reduction mechanism, and a wheel-type rope pressing mechanism as the rope pressing mechanism. Figure 8 , Figure 9 , Figure 10 As shown.

[0014] Furthermore, the connection and assembly position relationship of the disc motor, cycloidal pinwheel reduction mechanism, and wheel-type rope pressing mechanism of the suspended platform hoist of the present invention differs from that of the snail hoist. In the snail hoist, the reduction mechanism outputs power to the winding wheel (10) via the output shaft (11), and the wire rope is wound around the winding wheel (10) to achieve the upward and downward movement. In the suspended platform hoist of the present invention, the power output wheel of the cycloidal pinwheel reduction mechanism is directly designed as the winding wheel (25) of the wheel-type rope pressing mechanism (15), such as... Figure 9 As shown, this minimizes the size and weight of the suspended platform hoist, making its structure more compact and easier to install and use.

[0015] The beneficial effects of this invention are as follows:

[0016] This invention's suspended platform hoist effectively integrates the advantages of many hoists while avoiding their disadvantages by combining a disc motor, a cycloidal pinwheel reduction mechanism, and a wheel-type rope pressing mechanism. The suspended platform hoist of this invention directly designs the power output wheel of the cycloidal pinwheel reduction mechanism as the rope winding wheel (25) of the wheel-type rope pressing mechanism (15), minimizing the size and weight of the suspended platform hoist, making its structure more compact and easier to install and use.

[0112] To enhance understanding of the present invention, a suspended platform hoist will be further described in detail below with reference to examples and accompanying drawings. These embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0113] like Figure 8 As shown, the present invention provides a suspended platform hoist, comprising: a disc motor (17), a cycloidal pinwheel reduction mechanism (16), and a wheel-type rope pressing mechanism (15). The suspended platform hoist of the present invention directly designs the power output wheel of the cycloidal pinwheel reduction mechanism as the rope winding wheel (25) of the wheel-type rope pressing mechanism (15).

[0114] The combination connection method of the disc motor, cycloidal pinwheel reduction mechanism, and wheel-type rope pressing mechanism is as follows:

[0115] like Figure 9 As shown, first install the pin teeth (27) on the main housing (29). At the same time as installing the pin teeth (27), put the pin tooth sleeve (30) on the pin teeth (27) and install them together on the main housing (29). The disc motor (17) is connected to the main housing (29) by bolts (31). Put the washer (35) on the motor shaft (34) of the disc motor (17). The key (20) is embedded in the motor shaft (34). Install two cycloidal wheels. The cycloidal wheel markings need to be staggered by 180 degrees. First install the cycloidal wheel B (39), and then install the eccentric bearing (33). The eccentric bearing (33) cooperates with the key (20) and is installed on the motor shaft (34). On the cycloidal wheel B (39), it is just embedded in the center hole of the cycloidal wheel B (39). Place the spacer ring (26), install the cycloidal wheel A (37), the mark of the cycloidal wheel A (37) is offset from the mark of the cycloidal wheel B (39) by 180 degrees, the cycloidal wheel A (37) is just fitted on the eccentric bearing (33), put the pin sleeve (38) on the two cycloidal wheels, put the retaining ring (36) on the motor shaft (34), put the bearing A (22) on the set, install the snap ring (21), install the oil seal (32) on the main housing (29), add grease to the gaps between the bearing, cycloidal wheel, main housing, etc., for lubrication, the large pin shaft (24) and the winding wheel (25) (as Figure 11 As shown, the connection of the pin hole (55) is an interference fit. At this time, the winding wheel (25) together with the large pin (24) is installed into the cycloidal pin wheel reduction mechanism (16). The large pin (24) just passes into the pin sleeve (38). The bearing position A (57) of the winding wheel (25) is just fitted on the bearing A (22). The oil seal position (54) of the winding wheel (25) is just in contact with the oil seal (32). The bearing B (23) is fitted on the bearing position B (56) of the winding wheel (25). The rope pressing mechanism is assembled according to the assembly method of the wheel row type rope pressing mechanism (15) (refer to sections

[0018] and

[0019] ). Finally, the back cover (28) is installed.

[0116] like Figure 10 As shown, the rope pressing mechanism of the suspended platform hoist of the present invention includes: a main housing (29), a rope winding wheel (25), a wheel row (45), and a rope separator (51) (as shown). Figure 18 As shown), the rope inlet cap (46), rope inlet tube (48), rope outlet tube (49), and rope guide wheel (50).

[0117] The connection methods for the components of the rope pressing mechanism are as follows:

[0118] like Figure 10 As shown, there are three wheel rows (45), which are distributed and installed on the outer ring of the rope winding wheel (25). The center of the arc of the fan-shaped piece (41) of the wheel row (45) is the same as the center of the rope winding wheel (25). The small pressure wheel (44) of the pressure wheel assembly (43) is embedded in the groove (53) of the rope winding wheel (25). The rope separator (51) is installed at the upper right corner of the outer ring of the rope winding wheel (25). Figure 18 As shown), the wedge-shaped protrusion (75) of the rope separator (51) is embedded in the groove (53) of the rope winding wheel (25). The rope inlet tube (48) is installed vertically and is located in the tangential direction of the rope winding wheel (25). The upper end of the rope inlet tube (48) is connected to the rope inlet cap (46), and the lower end is connected to the rope inlet hole (76) of the rope separator (51). The direction of the rope outlet tube (49) is the same as the tangential direction of the rope winding wheel (25). The left end of the rope outlet tube (49) is connected to the rope outlet hole (74) of the rope separator (51), and the right end of the rope outlet tube (49) is connected to the main shell (29). An arc hole is opened on the lower right side of the rope outlet tube (49), and the center of the arc is the same as the center of the guide rope wheel (50). The guide rope wheel (50) is replaced by a custom bearing. The outer ring of the guide rope wheel (50) is machined with grooves and is fixed to the main shell (29) of the hoist with a bolt. The outer right side of the guide rope wheel (50) protrudes from the main shell (29).

[0119] The rope winding wheel (25) of the suspended basket hoist of the present invention, as shown in the figure Figure 11As shown, it includes: a groove (53), an oil seal position (54), a pin hole (55), a bearing position A (57), and a bearing position B (56). The rope reel is circular, with a groove (53) machined on the outer ring. The groove is used to place the wire rope (19). The oil seal position (54) contacts the oil seal (32) to prevent grease leakage. A pin hole (55) is provided around the inner ring for installing the large pin (24). Bearing position A (57) is used to install bearing A (22), and bearing position B (56) is used to install bearing B (23).

[0120] The wheel row (45) of the suspended platform hoist of the present invention, as shown in the figure Figure 12 As shown, it includes: 2 sector pieces (41) (as shown) Figure 15 As shown), 6 spring-loaded baffles (62) (as shown) Figure 16 As shown), 6 rope pressing wheel assemblies (43) (as shown) Figure 17 As shown), 6 springs (42), 4 thick support sleeves (63) (as shown) Figure 13 As shown), 3 thin support sleeves (66) (as shown) Figure 14 (As shown).

[0121] The connection method of each component of the wheel row (45) is as follows:

[0122] A spring (42) is fitted onto the guide rod (64) of the pressure rope wheel assembly (43), and then passes through the middle guide hole (69) of the spring stop plate (62). The rectangular boss (70) of the spring stop plate (62) cooperates with the rectangular mounting hole (60) of the fan-shaped plate (41). The sliding pin (65) cooperates with the sliding track (59) on the fan-shaped plate (41). The boss (67) of the thick support sleeve (63) cooperates with the mounting hole (58) of the fan-shaped plate (41). The boss (68) of the thin support sleeve (66) cooperates with the assembly hole (61) of the fan-shaped plate (41). The pressure wheel assembly (43) is installed radially between two fan-shaped plates (41) along the winding wheel (25). Under the constraint of the guide hole (69) in the middle of the spring stop (62) and the sliding track (59), the pressure wheel assembly (43) can slide radially along the winding wheel (25). The spring (42) pushes the small pressure wheel (44) to press the wire rope (19). Friction is generated between the wire rope (19) and the winding wheel (25), causing the wire rope to rotate with the winding wheel (25). The assembly hole (61) is used to assemble the wheel row (45) into a whole, and the mounting hole (58) is used to install and fix the wheel row (45) onto the main shell (29).

[0123] The rope pressing wheel assembly (43) of the suspended platform hoist of the present invention, as shown in the figure Figure 17 As shown, it includes: a small pressure roller (44), a graphite copper sleeve (72), a pin (73), an "n"-shaped support frame (71), a sliding pin (65), and a guide rod (64).

[0124] The connection method of each component of the rope pressing wheel assembly (43) is as follows:

[0125] The outer ring of the small pressure roller (44) has a groove, and a graphite copper sleeve (72) is embedded in the center. The pin (73) passes through the graphite copper sleeve (72) and is fixed to the "n"-shaped support frame (71) by riveting. The "n"-shaped support frame (71) has sliding pins (65) installed on both sides. The sliding pins (65) can be replaced by hexagonal bolts. The sliding pins (65) can slide along the sliding track (59) on the fan-shaped piece (41) to play a positioning and guiding role. The top of the "n"-shaped support frame (71) is riveted with a guide rod (64).

[0126] To facilitate compatibility with the mounting bracket of the double-pressure roller hoist, the mounting holes A (40), B (47), and C (52) of the suspended platform hoist of this invention are positioned in the same relative positions as the mounting holes A (5), B (4), and C (6) of the double-pressure roller hoist. Specifically, the diameters of mounting holes A (40), B (47), and C (52) are equal to the diameters of mounting holes A (5), B (4), and C (6), respectively, and the distances between mounting holes A (40), B (47), and C (52) are equal to the distances between mounting holes A (5), B (4), and C (6), respectively. Figure 2 , Figure 10 As shown.

[0127] like Figure 10 As shown, during the use of the suspended platform hoist of the present invention, the travel path of the wire rope (19) is as follows: the wire rope (19) passes through the rope inlet cap (46), the rope inlet tube (48), and the rope inlet hole (76) of the rope separator (51) in sequence. Under the push of 18 small pressure rollers (44), the wire rope (19) is tightly attached to the groove (53) of the winding wheel (25). Under the frictional force between the wire rope (19) and the groove (53), the wire rope... As the rope (19) rotates with the winding wheel (25), the wire rope (19) wraps around the winding wheel (25) once and leaves the winding wheel (25) at the rope outlet hole (74) of the rope separator (51), and enters the rope outlet hole (74) and the rope outlet tube (49) in sequence. The rope outlet tube (49) has an opening at the lower right and is connected to the guide wheel (50). Under the action of the guide wheel (50), the wire rope (19) comes out from the hoist housing (29) and hangs down naturally.

[0128] The suspended platform hoist of the present invention is very simple and convenient to manufacture. It can be processed according to the general machining process as shown in the attached drawings of the instruction manual. The disc motor (17) has professional manufacturers, and the size and power can be customized as needed; the cycloidal pinwheel reduction mechanism (16) also has professional manufacturers, and each part can be customized as needed; the main shell (29) and the rear cover (28) are molded and processed by CNC machining center; the rope winding wheel (25) is processed by lathe and drilling machine, and nitriding heat treatment process; the arc opening of the fan-shaped plate (41), spring baffle (62), and rope tube (49) is laser cutting technology; the "n" shape of the "n"-shaped support frame (71) is stamped; the holes and threads of the "n"-shaped support frame (71) are drilled and tapped by bench drill. The guide wheel (50) and small pressure wheel (44) are both custom bearings, using bearing-related processing technology; the sliding pin (65) is a standard hexagonal bolt part, which can be purchased on the market; the guide rod (64), large pin (24), pin (73), rope inlet cap (46), rope inlet tube (48), rope outlet tube (49), coarse support sleeve (63), and fine support sleeve (66) are machined using lathe technology; the graphite copper sleeve (72) has a professional manufacturer, and the size can be customized; the spring (42) can be produced using professional spring equipment; the rope separator (51) uses precision casting technology; the connection of each component uses welding, riveting, bolting and other connection technologies.
