Description

TECHNICAL FIELD

[0001] The present application relates to a kind of high operation machinery lifting device, especially a kind of high operation basket lifting machine. BACKGROUND

[0002] High operation basket is a new type of high operation machinery that can replace traditional scaffold, reduce labor intensity, improve work efficiency and be reused.The basket suspension platform of high operation basket is mainly lifted by steel wire rope winding of basket lifting machine to realize ascending and descending operation, so the basket lifting machine is one of the key equipment of high operation basket, and its performance directly affects the safety performance and work efficiency of high operation basket.

[0003] The existing basket lifting machine is mainly divided into two types according to the winding mode of steel wire rope, "α" type lifting machine and "S" type lifting machine.Among them, "α" type lifting machine is divided into snail type lifting machine, double compression wheel lifting machine and wheel row type lifting machine according to the structure of steel wire rope compression, and the current market share is the largest, and the most commonly used is double compression wheel lifting machine, such as shown in the figure. Figure 3 Wheel row type lifting machine is a new type of anti-blocking rope lifting machine, and there are such products on the market.The detailed description of wheel row type lifting machine is shown in the figure. Figure 2

[0004] In the market, the use of high operation basket with traditional structure is the largest, and some special-shaped structure baskets need to be designed to complete some special work, for example, two suspension platforms are hung on a set of steel wire rope, and each suspension platform can independently realize ascending and descending operation (as shown in the figure). Figure 1 In order to realize the above operation, the steel wire rope comes out from the lifting machine of the upper suspension platform and then enters the lifting machine of the lower suspension platform, and the steel wire ropes of the two lifting machines are on the same vertical line, that is, the steel wire rope at the entry position of the upper lifting machine and the steel wire rope at the exit position are on the same vertical line.

[0005] Analysis of the current market lifting machine, the steel wire rope at the entry position of "s" shape rope lifting machine and the steel wire rope at the exit position are not on the same vertical line;The steel wire rope at the entry position of snail type lifting machine and the steel wire rope at the exit position are not on the same vertical line;Wheel row type lifting machine and snail type lifting machine have similar rope running mode, and also not on the same vertical line (as shown in the figure);The horizontal distance between the steel wire rope at the entry position and the steel wire rope at the exit position is the smallest, which is double compression wheel lifting machine (as shown in the figure). Figure 2 Figure 3

[0006] ​​​Further analysis of the double-pressure wheel hoist reveals that, strictly speaking, the wire ropes at the inlet and outlet of the double-pressure wheel hoist are not on the same vertical line, but are offset by a small distance. Furthermore, if the double-pressure wheel hoist is equipped with only one suspended platform, the maximum weight that the rope divider (6) can bear is the total weight of the wire rope, approximately 30 kg (calculated based on a wire rope diameter of 8.3 mm and a length of 120 meters). If the double-pressure wheel hoist is equipped with two suspended platforms, the maximum weight that the rope divider can bear is 315 kg (calculated based on a rated load of 630 kg for the second suspended platform). Bearing 315 kg, the wear between the rope divider and the wire rope is excessive. Therefore, the double-pressure wheel hoist cannot meet the design requirements for a double suspended platform. Summary of the Invention

[0007] The technical problem to be solved by this invention:

[0008] To accomplish certain specialized tasks, some irregularly shaped suspended platforms require two suspended platforms to be attached to a set of steel wire ropes, with each platform capable of independent ascent and descent (e.g., Figure 1 (As shown). To achieve the above operation, the wire rope exits from the upper hoist and then enters the lower hoist. The wire ropes of both hoists must be on the same vertical line. That is, the wire rope at the rope inlet and the wire rope at the rope outlet of the upper hoist must be on the same vertical line, which can be simply described as: the inlet and outlet ropes are collinear. Analysis shows that currently available hoists do not meet the technical requirement of "collim and outlet ropes being collinear".

[0009] Therefore, it is necessary to design a new type of hoist to meet the technical requirement that the wire rope at the rope inlet and the wire rope at the rope outlet are on the same vertical line, that is, the rope inlet and rope outlet are collinear.

[0010] The present invention adopts the following technical solution:

[0011] like Figure 4 As shown, this invention provides a suspended platform hoist, the wire rope winding path of which is similar to the Greek letter "Ω", hence it is called an "Ω" type hoist. The suspended platform hoist of this invention includes: a hoist housing (8), a large rope winding wheel (12), a small rope winding wheel A (7), a small rope winding wheel B (16), a large wheel row A (10), a large wheel row B (11), a large wheel row C (15), and a small wheel row A (19) (as shown). Figure 17 As shown), small wheel row B (24), rope guide A (9) (as shown) Figure 8 As shown), rope guide B (14) (as shown) Figure 9 As shown), rope guide C (13) (as shown) Figure 10As shown), rope guide wheel A (20), rope guide wheel B (21), rope guide wheel C (22), rope guide wheel D (23), rope inlet cap (17), rope inlet tube (18), rope outlet tube (25), rope outlet cap (26).

[0012] The connection methods for each component are as follows:

[0013] like Figure 4 As shown, the outer circles of the large rope wheel (12), the small rope wheel A (7), and the small rope wheel B (16) are all machined with grooves in the shape of trapezoids. The three rope wheels are installed on the same vertical plane in the orientation shown in the figure. The centers of the small rope wheel A (7) and the small rope wheel B (16) are on the same vertical line. The included angle formed by the centers of the three rope wheels with the center of the large rope wheel as the vertex is 75 degrees. The distance between the outer circle of the large rope wheel (12) and the outer circles of the two small rope wheels is 2 mm. Large rope winding wheel (12) is surrounded by large wheel rows A (10), B (11), and C (15). The center of the fan-shaped arc of the three large wheel rows is the same as the center of the large rope winding wheel (12). A rope guide A (9) is installed between the large rope winding wheel (12) and the small rope winding wheel A (7). The wedge-shaped protrusion (40) of the rope guide A (9) is just embedded in the trapezoidal groove of the small rope winding wheel A (7). Between the large rope winding wheel (12) and the small rope winding wheel B (16) Install rope guide B (14), the wedge-shaped protrusion (41) of rope guide B (14) fits perfectly into the trapezoidal groove (37) of small rope winding wheel B (16); install rope guide C (13) between large rope winding wheel (12), small rope winding wheel A (7) and small rope winding wheel B (16), the wedge-shaped protrusion (44) of rope guide C (13) fits perfectly into the trapezoidal groove (35) of large rope winding wheel (12); rope stop wheel A (20), rope stop wheel B (21), rope stop wheel C ( 22) The rope guide wheel D (23) is installed between the small rope guide wheel A (7) and the small rope guide wheel B (16) as shown in the figure. The rope guide wheel A (20) and the rope guide wheel B (21) are tangent to the small rope guide wheel A (7) and are installed below the small rope guide wheel A (7). The rope guide wheel C (22) and the rope guide wheel D (23) are tangent to the small rope guide wheel B (16) and are installed above the small rope guide wheel B (16). The small wheel row A (19) and the small wheel row B (24) are installed as shown in the figure. They are respectively installed on the right side of small rope winding wheel A (7) and small rope winding wheel B (16). The uppermost rope pressing wheel assembly of small wheel row A (19) is located in the horizontal direction, and the lowermost rope pressing wheel assembly of small wheel row B (24) is also located in the horizontal direction. The rope inlet cap (17) and rope inlet pipe (18) are installed vertically at the rope inlet position of the hoist housing (8) as shown in the figure. The rope outlet cap (26) and rope outlet pipe (25) are installed vertically at the rope outlet position of the hoist housing (8) as shown in the figure.

[0014] The hoist of the present invention has the following wire rope winding path: the wire rope (3) at the inlet position passes vertically downward through the inlet cap (17), the inlet tube (18), and enters between the small pulley row A (19) and the small winding pulley A (7). It rotates along the groove of the small winding pulley A (7) and passes through the three small pressure rollers of the small pulley row A (19), the rope blocking roller A (20), the rope blocking roller B (21), and the rope guide C (13). Under the action of the wedge-shaped protrusion (40) of the rope guide A (9), the wire rope enters between the large pulley row A (10) and the large winding pulley (12) and moves along the groove of the large winding pulley (12). The wire rope rotates through the groove (35) of the large wheel row A (10), the large wheel row B (11), the large wheel row C (15) with 15 small pressure rollers and the rope guide B (14). Under the action of the wedge-shaped protrusion (44) of the rope guide C (13), the wire rope enters between the small winding wheel B (16) and the rope blocking wheel C (22), rotates along the groove (37) of the small winding wheel B (16), passes through the rope blocking wheel C (22), the rope blocking wheel D (23), the small wheel row B (24) with 3 small pressure rollers, enters the rope outlet pipe (25), the rope outlet cap (26), and finally comes out from the hoist housing (8).

[0015] In this invention, the suspended platform hoist winds a wire rope through the grooves of a large winding sheave (12), a small winding sheave A (7), and a small winding sheave B (16), requiring that the linear velocity at the axis of the wire rope be the same. This requirement of the same linear velocity at the axis of the wire rope can be achieved through gear meshing. For example... Figure 7 As shown, Figure 4 In the sectional view along the AA direction, the driving gear (28) is machined with internal and external teeth. The diameter, number of teeth, and module of the internal teeth are the same as those of the existing double pressure roller hoist. The driving gear (28) drives the driven gear B (29) to rotate through gear meshing. The large rope wheel (12) is assembled with the driving gear (28) by a key. The small rope wheel B (16) is also assembled with the driven gear B (29) by a key. The large oil seal (31) and the small oil seal B (32) isolate the gear meshing space of the driving gear (28) and the driven gear B (29) from the rope winding space of the large rope wheel (12) and the small rope wheel B (16) to prevent gear oil leakage. The driving gear (28) is fixed to the hoist housing (8) by bearings E (33) and G (36). The driven gear B (29) is fixed to the hoist housing (8) by bearings F (34) and H (38).

[0016] like Figure 5 The diagram shows the dimensions, installation positions, and meshing methods of the driving gear (28), driven gear A (27), and driven gear B (29).

[0017] like Figure 6As shown, the size and installation position of the large oil seal (31), the small oil seal A (30), and the small oil seal B (32) are shown.

[0018] The large wheel row A (10), the large wheel row B (11), and the large wheel row C (15) of the hanging basket hoist of the application are completely the same in shape, structure, and material, and only the large wheel row A (10) is taken as an example for description. As shown in the figure, Figure 11 The large wheel row A (10) includes two large fan-shaped pieces (51) (as shown in the figure, Figure 12 As shown in the figure), five spring stop pieces (46) (as shown in the figure), Figure 15 As shown in the figure), five rope pressing wheel assemblies (48) (as shown in the figure), five springs (47), four thick support sleeve tubes (54) (as shown in the figure), and two thin support sleeve tubes (53) (as shown in the figure). Figure 16 Figure 13 Figure 14

[0019] The combination and connection mode of the components of the large wheel row A (10) are as follows:

[0020] The spring (47) is sleeved on the guide rod (45) of the rope pressing wheel assembly (48), and then passes through the middle guide hole (60) of the spring stop piece (46). The rectangular boss (61) of the spring stop piece (46) is matched with the rectangular mounting hole (52) of the large fan-shaped piece (51). The sliding pin (49) is matched with the sliding track (55) on the upper surface of the large fan-shaped piece (51). The boss (58) of the thick support sleeve tube (54) is matched with the mounting hole (57) of the large fan-shaped piece (51). The boss (59) of the thin support sleeve tube (53) is matched with the assembly hole (56) of the large fan-shaped piece (51). The rope pressing wheel assembly (48) is installed in the middle of the two large fan-shaped pieces (51) along the radial direction of the large rope winding wheel (12). The rope pressing wheel assembly (48) can slide along the radial direction of the large rope winding wheel (12) under the constraint of the middle guide hole (60) of the spring stop piece (46) and the sliding track (55). The spring (47) pushes the small pressing wheel (50) to press the steel wire rope. The friction force is generated between the steel wire rope and the large rope winding wheel (12), so that the steel wire rope rotates with the large rope winding wheel (12).

[0021] The rope pressing wheel assembly (48) of the hanging basket hoist of the application, as shown in the figure, Figure 16 includes the small pressing wheel (50), the graphite copper sleeve (64), the pin shaft (65), the “U” type support frame (62), the sliding pin (49), and the guide rod (45).

[0022] The combination and connection mode of the components of the rope pressing wheel assembly (48) are as follows:

[0023] ​​​The outer ring of the small press wheel (50) is machined with a groove, a graphite copper sleeve (64) is embedded at the center position, a pin shaft (65) penetrates the graphite copper sleeve (64), and is fixed on the U-shaped support frame (62) by riveting, the U-shaped support frame (62) is provided with sliding pins (49) on both sides, the sliding pins (49) can be replaced by internal hexagonal bolts, the sliding pins (49) can slide along the sliding track (55) on the large sector (51), and the sliding pins (49) play a positioning and guiding role, and the U-shaped support frame (62) is riveted with a guide rod (45) at the top.

[0024] The small wheel row A (19) and the small wheel row B (24) of the hanging basket elevator are completely same in shape and structure except that the installation positions are different. The center of the sector arc of the small sector (66) (as shown in the figure) of the small wheel row A is same as the center of the small rope winding wheel A (7), and three rope pressing wheel assemblies are installed. Figure 18 Except the small sector (66), the shapes and structures of other parts such as the rope pressing wheel assembly, the spring check piece, the spring, the thick support sleeve and the thin support sleeve are same as those of the large wheel row A (10).

[0025] The hanging basket elevator has the advantages that:

[0026] The hanging basket elevator of the application meets the technical requirement of "co-linear entering and exiting of the rope" by designing the steel wire rope to pass through the elevator in the "Ω" type path, so that the steel wire rope at the entering position on the elevator and the steel wire rope at the exiting position below the elevator are on the same vertical line, and two suspension platforms can be hung on a group of steel wire ropes, and each suspension platform can independently realize the ascending and descending operation.

The three rope wheels are installed in the same vertical plane according to the indicated orientation. The centers of the small rope wheel A (7) and the small rope wheel B (16) are on the same vertical line. The included angle of the centers of the three rope wheels, with the center of the large rope wheel as the vertex, is 75 degrees. The distance between the outer circle of the large rope wheel (12) and the outer circles of the two small rope wheels is 2 mm. The outer circle of the large rope wheel (12) is installed around the large wheel row A (10), the large wheel row B (11), and the large wheel row C (15). The centers of the fan-shaped arcs of the three large wheel rows are at the same position as the center of the large rope wheel (12). The guide rope device A (9) is installed between the large rope wheel (12) and the small rope wheel A (7). The wedge-shaped protrusion (40) of the guide rope device A (9) is embedded in the trapezoidal groove of the small rope wheel A (7). The guide rope device B (14) is installed between the large rope wheel (12) and the small rope wheel B (16).

The guide rope device C (13) is installed between the large rope wheel (12), the small rope wheel A (7), and the small rope wheel B (16). The wedge-shaped protrusion (44) of the guide rope device C (13) is embedded in the trapezoidal groove (35) of the large rope wheel (12). The rope blocking wheel A (20), the rope blocking wheel B (21), the rope blocking wheel C (22), and the rope blocking wheel D (23) are installed between the small rope wheel A (7) and the small rope wheel B (16) according to the indicated positions. Among them, the rope blocking wheel A (20) and the rope blocking wheel B (21) are tangent to the small rope wheel A (7) and are installed below the small rope wheel A (7). The rope blocking wheel C (22) and the rope blocking wheel D (23) are tangent to the small rope wheel B (16) and are installed above the small rope wheel B (16). The small wheel row A (19) and the small wheel row B (24) are installed on the right sides of the small rope wheel A (7) and the small rope wheel B (16), respectively, according to the indicated positions. The uppermost pressure rope wheel assembly of the small wheel row A (19) is located in the horizontal direction, and the lowermost pressure rope wheel assembly of the small wheel row B (24) is also located in the horizontal direction. The rope inlet cap (17) and the rope inlet pipe (18) are installed vertically at the rope inlet position of the elevator housing (8) according to the indicated positions. The rope outlet cap (26) and the rope outlet pipe (25) are installed vertically at the rope outlet position of the elevator housing (8) according to the indicated positions.

[0115] The hoist of the present invention has the following wire rope winding path: the wire rope (3) at the inlet position passes vertically downward through the inlet cap (17), the inlet tube (18), and enters between the small pulley row A (19) and the small winding pulley A (7). It rotates along the groove of the small winding pulley A (7) and passes through the three small pressure rollers of the small pulley row A (19), the rope blocking roller A (20), the rope blocking roller B (21), and the rope guide C (13). Under the action of the wedge-shaped protrusion (40) of the rope guide A (9), the wire rope enters between the large pulley row A (10) and the large winding pulley (12) and moves along the groove of the large winding pulley (12). The wire rope rotates through the groove (35) of the large wheel row A (10), the large wheel row B (11), the large wheel row C (15) with 15 small pressure rollers and the rope guide B (14). Under the action of the wedge-shaped protrusion (44) of the rope guide C (13), the wire rope enters between the small winding wheel B (16) and the rope blocking wheel C (22), rotates along the groove (37) of the small winding wheel B (16), passes through the rope blocking wheel C (22), the rope blocking wheel D (23), the small wheel row B (24) with 3 small pressure rollers, enters the rope outlet pipe (25), the rope outlet cap (26), and finally comes out from the hoist housing (8).

[0116] In this invention, the suspended platform hoist winds a wire rope through the grooves of a large winding sheave (12), a small winding sheave A (7), and a small winding sheave B (16), requiring that the linear velocity at the axis of the wire rope be the same. This requirement of the same linear velocity at the axis of the wire rope can be achieved through gear meshing. For example... Figure 7 As shown, Figure 4 In the sectional view along the AA direction, the driving gear (28) is machined with internal and external teeth. The diameter, number of teeth, and module of the internal teeth are the same as those of the existing double pressure roller hoist. The driving gear (28) drives the driven gear B (29) to rotate through gear meshing. The large rope wheel (12) is assembled with the driving gear (28) by a key. The small rope wheel B (16) is also assembled with the driven gear B (29) by a key. The large oil seal (31) and the small oil seal B (32) isolate the gear meshing space of the driving gear (28) and the driven gear B (29) from the rope winding space of the large rope wheel (12) and the small rope wheel B (16) to prevent gear oil leakage. The driving gear (28) is fixed to the hoist housing (8) by bearings E (33) and G (36). The driven gear B (29) is fixed to the hoist housing (8) by bearings F (34) and H (38).

[0117] like Figure 5 The diagram shows the dimensions, installation positions, and meshing methods of the driving gear (28), driven gear A (27), and driven gear B (29).

[0118] like Figure 6As shown, the size and installation position of the large oil seal (31), the small oil seal A (30), and the small oil seal B (32) are shown.

[0119] The large wheel row A (10), the large wheel row B (11), and the large wheel row C (15) of the hanging basket hoist of the application are completely the same in shape, structure, and material, and only the large wheel row A (10) is taken as an example for description. As shown in the figure, Figure 11 The large wheel row A (10) includes two large fan-shaped pieces (51) (as shown in the figure, Figure 12 five spring stop pieces (46) (as shown in the figure, Figure 15 five rope pressing wheel assemblies (48) (as shown in the figure, Figure 16 five springs (47), four thick support sleeve tubes (54) (as shown in the figure, Figure 13 and two thin support sleeve tubes (53) (as shown in the figure).

The rope pressing wheel assembly (48) can slide along the radial direction of the large rope winding wheel (12) under the constraint of the middle guide hole (60) of the spring stop piece (46) and the sliding track (55). The spring (47) pushes the small pressing wheel (50) to press the steel wire rope. The friction force between the steel wire rope and the large rope winding wheel (12) makes the steel wire rope rotate with the large rope winding wheel (12).

[0122] The rope pressing wheel assembly (48) of the hanging basket hoist of the application, as shown in the figure, Figure 16 includes a small pressing wheel (50), a graphite copper sleeve (64), a pin shaft (65), a "U"-shaped support frame (62), a sliding pin (49), and a guide rod (45).
