Description

Technical Field

[0001] The utility model belongs to the technical field of double-drum hoisting, and relates to a four-rope balance beam device, in particular to an adjustable double-drum four-rope balance beam device. Background Technique

[0002] The adjustable double-drum hoisting technology is an efficient, flexible and safe hoisting solution. Its core feature is the use of a double-drum design. By synchronously or asynchronously controlling the operation of the two drums, the alternate winding and unwinding of cables or steel wires are realized. This technology not only improves the hoisting efficiency but also enhances the safety and stability of the hoisting process.

[0003] Existing double-drum hoisting devices have technical problems such as the inability to compensate and adjust the errors caused during the processing of the four wire rope grooves and insufficient longitudinal working space.

[0004] Based on this, we propose an adjustable double-drum four-rope balance beam device, which can compensate and adjust the errors caused during the processing of the four wire rope grooves, has a more sufficient longitudinal working space, and higher working efficiency. Content of the Utility Model

[0005] The purpose of the utility model is to address the above-mentioned problems existing in the prior art and propose an adjustable double-drum four-rope balance beam device. The technical problem to be solved by this utility model is: how to enable the adjustable double-drum to compensate and adjust the errors caused during the processing of the four wire rope grooves during hoisting, have a more sufficient longitudinal working space, and higher working efficiency.

[0006] The purpose of the utility model can be achieved by the following technical solutions:

[0007] An adjustable double-drum four-rope balance beam device includes a wedge sleeve, an I-shaped lower hanging part and a frame. The I-shaped lower hanging part is fixed on the frame. A longitudinal beam connecting piece is provided at the upper end of the frame. A longitudinal beam is provided at the upper end of the longitudinal beam connecting piece. Adjusting mechanisms I are provided at both ends of the longitudinal beam. A transverse beam is provided at the upper end of the adjusting mechanism I. Connecting mechanisms are provided at both ends of the transverse beam. A chain plate assembly is provided at the upper end of the connecting mechanism. The wedge sleeve is rotatably arranged on the chain plate assembly. A steel rope is provided on the wedge sleeve.

[0008] The working principle of the utility model is as follows: The upper end of the steel rope is wound around the drum on the overhead traveling crane. The wedge sleeve is used to lock the steel rope. The error caused during the processing of the steel wire rope groove will result in uneven distances when the steel ropes descend synchronously, causing a small deviation in the horizontal position of the two cross beams. The connection mechanism and the link plate assembly cooperate to enable the cross beam and the steel rope to rotate relative to the cross direction, making the connection more stable. The first adjusting mechanism enables the cross beam and the longitudinal beam to rotate relative to each other in the transverse direction to compensate for the error of the steel wire rope groove. The first adjusting mechanism keeps the cross beam and the longitudinal beam fixed in the longitudinal direction, ensuring that the longitudinal beam body is always in a horizontal state, improving the working stability. The longitudinal beam connecting piece enables the frame to swing slightly in the longitudinal direction, increasing the working space of the I-shaped lower hanging piece and improving the working efficiency.

[0009] The longitudinal beam includes a longitudinal beam body. The center of the longitudinal beam body is rotatably arranged on the longitudinal beam connecting piece. Longitudinal beam shafts are rotatably provided at both ends of the longitudinal beam body. Fixing plates are connected to both ends of the longitudinal beam body by screws. The specifications of the fixing plates match those of the longitudinal beam shafts.

[0010] With the above structure, the longitudinal beam connecting piece offsets the lateral deviation of the longitudinal beam body through rotation with the longitudinal beam body, improving the stability during work.

[0011] The first adjusting mechanism includes a first U-shaped plate. The first U-shaped plate is rotatably arranged on the longitudinal beam shaft. The first U-shaped plate is pressed against the longitudinal beam body by the fixing plate in the transverse direction. Two symmetrically arranged first connecting plates are fixed to the upper end of the first U-shaped plate.

[0012] With the above structure, the limitation that the first U-shaped plate receives in the longitudinal direction can ensure that the longitudinal beam body is always in a horizontal state, improving the working stability.

[0013] The cross beam includes a cross beam body and a cross beam shaft. The center of the cross beam body is rotatably arranged between the two first connecting plates through the cross beam shaft. U-shaped connecting blocks are fixed to the upper sides of both ends of the cross beam body.

[0014] With the above structure, the cross beam shaft enables the cross beam body and the first connecting plate to rotate transversely, thereby enabling the cross beam body and the longitudinal beam body to rotate transversely.

[0015] The connection mechanism includes a connection screw, a U-shaped plate shaft, and a second U-shaped plate. The second U-shaped plate is rotatably arranged on the corresponding connecting block through the U-shaped plate shaft. The lower end of the second U-shaped plate is rotatably arranged on the U-shaped plate shaft. A second connecting plate is fixed to the inner side of the upper end of the second U-shaped plate. A through hole is formed inside the second connecting plate. The lower end of the connection screw passes through the through hole inside the second connecting plate. Nuts are screwed on both sides of the lower end of the connection screw where it is located. The connection screw is locked and fixed to the second connecting plate by the two nuts.

[0016] With the above structure, the two nuts are tightened relative to each other to fix the connecting screw rod on the second connecting plate. The U-shaped plate shaft enables lateral rotation between the second U-shaped plate and the connecting block, thereby enabling lateral rotation between the second U-shaped plate and the lateral beam body.

[0017] The chain plate assembly includes two chain plates. Between the two chain plates, two pin shafts distributed up and down are rotatably arranged. The lower pin shaft is rotatably arranged at the upper end of the corresponding connecting screw rod. The two chain plates are fixedly connected through these two pin shafts. A third connecting plate is rotatably arranged on the upper pin shaft. The third connecting plate is located between the two chain plates, and the upper end of the third connecting plate is rotatably arranged on the wedge sleeve through a pin shaft.

[0018] With the above structure, the pin shaft on the third connecting plate enables lateral rotation between the wedge sleeve and the two chain plates. The pin shaft rotatably connected to the connecting screw rod enables lateral rotation between the two chain plates and the connecting screw rod. Thus, the pin shaft enables lateral rotation between the wedge sleeve and the second U-shaped plate, and further enables lateral rotation between the wedge sleeve and the lateral beam body, and enables lateral rotation between the steel rope and the lateral beam body.

[0019] Compared with the prior art, the adjustable double-drum four-rope balance beam device has the following advantages:

[0020] 1. Through the cooperation of the wedge sleeve and the steel rope, stable connection between the wedge sleeve and the steel rope is achieved;

[0021] 2. Through the cooperation of the connecting mechanism and the chain plate assembly, lateral rotation of the lateral beam is achieved, making the connection more stable and the lateral force balanced;

[0022] 3. Through the cooperation of the longitudinal beam with the longitudinal beam connecting piece and two first adjusting mechanisms respectively, the error of the steel wire rope groove is compensated, longitudinal rotation of the longitudinal beam connecting piece is achieved, and at the same time, the I-shaped lower hanging piece works more stably;

[0023] 4. Through the cooperation of the I-shaped lower hanging piece, the longitudinal beam connecting piece and the frame, the frame can swing slightly longitudinally, increasing the longitudinal working space of the I-shaped lower hanging piece and improving work efficiency.

Detailed implementation mode

[0029] The following are specific embodiments of the present invention and, in conjunction with the accompanying drawings, further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0030] As Figures 1-4 shown, this adjustable double-drum four-rope balance beam device includes a wedge sleeve 9, an I-shaped lower suspension 1 and a frame 2. The I-shaped lower suspension 1 is fixed on the frame 2. A longitudinal beam connecting member 3 is provided at the upper end of the frame 2. A longitudinal beam 4 is provided at the upper end of the longitudinal beam connecting member 3. First adjusting mechanisms 5 are provided at both ends of the longitudinal beam 4. A transverse beam 6 is provided at the upper end of the first adjusting mechanism 5. Connecting mechanisms 7 are provided at both ends of the transverse beam 6. A chain plate assembly 8 is provided at the upper end of the connecting mechanism 7. The wedge sleeve 9 is rotatably arranged on the chain plate assembly 8. A steel rope 10 is provided on the wedge sleeve 9.

[0031] In this embodiment, the upper end of the steel rope 10 is wound around the drum on the overhead crane. The wedge sleeve 9 is used to lock the steel rope 10. Errors in the processing of the wire rope groove will cause the distances of the steel rope 10 to be uneven during synchronous descent, resulting in a small offset of the two transverse beams 6 in the horizontal position. The connecting mechanism 7 and the chain plate assembly 8 cooperate to enable the transverse beam 6 and the steel rope 10 to rotate relative to the transverse direction, making the connection more stable. The first adjusting mechanism 5 enables the transverse beam 6 and the longitudinal beam 4 to rotate relative to each other in the transverse direction to compensate for the error of the wire rope groove. The first adjusting mechanism 5 keeps the transverse beam 6 and the longitudinal beam 4 fixed in the longitudinal direction, so that the longitudinal beam body 401 is always in a horizontal state, improving the working stability. The longitudinal beam connecting member 3 enables the frame 2 to swing slightly in the longitudinal direction, increasing the working space of the I-shaped lower suspension 1 and improving the working efficiency.

[0032] The longitudinal beam 4 includes a longitudinal beam body 401. The center of the longitudinal beam body 401 is rotatably arranged on the longitudinal beam connecting member 3. Longitudinal beam shafts 402 are rotatably provided at both ends of the longitudinal beam body 401. Fixing plates 403 are connected to both ends of the longitudinal beam body 401 by screws. The specifications of the fixing plates 403 match the specifications of the longitudinal beam shafts 402.

[0033] In this embodiment, the longitudinal beam connector 3 offsets the lateral offset of the longitudinal beam body 401 by rotating with the longitudinal beam body 401, improving the stability during operation.

[0034] The first adjusting mechanism 5 includes a first U-shaped plate 501 which is rotatably arranged on the longitudinal beam axis 402. The first U-shaped plate 501 is tightly pressed against the longitudinal beam body 401 in the lateral direction by a fixing plate 403. Two symmetrically arranged first connecting plates 502 are fixed to the upper end of the first U-shaped plate 501.

[0035] In this embodiment, the limitation of the first U-shaped plate 501 in the longitudinal direction can keep the longitudinal beam body 401 in a horizontal state all the time, improving the working stability.

[0036] The transverse beam 6 includes a transverse beam body 601 and a transverse beam axis 602. The center of the transverse beam body 601 is rotatably arranged between two first connecting plates 502 through the transverse beam axis 602. U-shaped connecting blocks 603 are fixed to the upper sides of both ends of the transverse beam body 601.

[0037] In this embodiment, the transverse beam axis 602 enables the transverse rotation between the transverse beam body 601 and the first connecting plates 502, so as to realize the transverse rotation between the transverse beam body 601 and the longitudinal beam body 401.

[0038] The connecting mechanism 7 includes a connecting screw 705, a U-shaped plate shaft 701 and a second U-shaped plate 702. The second U-shaped plate 702 is rotatably arranged on the corresponding connecting block 603 through the U-shaped plate shaft 701. The lower end of the second U-shaped plate 702 is rotatably arranged on the U-shaped plate shaft 701. A second connecting plate 704 is fixed to the inner side of the upper end of the second U-shaped plate 702. A through hole is formed inside the second connecting plate 704. The lower end of the connecting screw 705 passes through the through hole inside the second connecting plate 704. Nuts 703 are screwed on both sides of the lower end of the connecting screw 705 where it is located inside the second connecting plate 704. The connecting screw 705 is locked and fixed to the second connecting plate 704 by two nuts 703.

[0039] In this embodiment, the two nuts 703 are locked relatively to fix the connecting screw 705 to the second connecting plate 704. The U-shaped plate shaft 701 enables the transverse rotation between the second U-shaped plate 702 and the connecting block 603, so as to realize the transverse rotation between the second U-shaped plate 702 and the transverse beam body 601.

[0040] The chain plate assembly 8 includes two chain plates 801. Between the two chain plates 801, two pin shafts are rotatably arranged in an up-and-down distribution. The lower pin shaft is rotatably arranged at the upper end of the corresponding connecting screw 705. The two chain plates 801 are fixedly connected through these two pin shafts. On the upper pin shaft, a third connecting plate 802 is rotatably arranged. The third connecting plate 802 is located between the two chain plates 801, and the upper end of the third connecting plate 802 is rotatably arranged on the wedge sleeve 9 through a pin shaft.

[0041] In this embodiment, the pin shaft on the third connecting plate 802 enables lateral rotation between the wedge sleeve 9 and the two chain plates 801. The pin shaft rotatably connected to the connecting screw 705 enables lateral rotation between the two chain plates 801 and the connecting screw 705, so that the pin shaft enables lateral rotation between the wedge sleeve 9 and the second U-shaped plate 702, so that the pin shaft enables lateral rotation between the wedge sleeve 9 and the transverse beam body 601, so that lateral rotation is achieved between the steel rope 10 and the transverse beam body 601.

[0042] The working principle of the present utility model: Errors brought about during the processing of the wire rope groove will cause the distances of the steel rope 10 to be uneven when synchronously descending, causing small displacements in the horizontal positions of the two transverse beam shafts 602. The pin shaft on the third connecting plate 802 enables lateral rotation between the wedge sleeve 9 and the two chain plates 801. The pin shaft rotatably connected to the connecting screw 705 enables lateral rotation between the two chain plates 801 and the connecting screw 705. The two nuts 703 are relatively locked to fix the connecting screw 705 on the second connecting plate 704. The U-shaped plate shaft 701 enables lateral rotation between the second U-shaped plate 702 and the connecting block 603, so that lateral rotation is achieved between the second U-shaped plate 702 and the transverse beam body 601, so that lateral rotation is achieved between the steel rope 10 and the transverse beam body 601, making the connection more stable. The limit on the second U-shaped plate 501 in the longitudinal direction can keep the longitudinal beam body 401 always in a horizontal state. The transverse beam shaft 602 enables lateral rotation between the transverse beam body 601 and the first connecting plate 502, so that lateral rotation is achieved between the transverse beam body 601 and the longitudinal beam body 401, compensating for the error of the wire rope groove. The longitudinal beam connecting piece 3 rotates slightly longitudinally with the longitudinal beam body 401 to offset the lateral displacement of the longitudinal beam body 401. The longitudinal beam connecting piece 3 enables the frame 2 to swing slightly longitudinally, increasing the working space of the I-shaped lower hanging piece 1 and improving work efficiency.

[0043] In summary, through the cooperation of the wedge sleeve 9 and the steel rope 10, stable connection between the wedge sleeve 9 and the steel rope 10 is achieved;

[0044] Through the cooperation of the connecting mechanism 7 and the chain plate assembly 8, lateral rotation of the transverse beam 6 is achieved, making the connection more stable and the lateral force balanced;

[0045] By respectively cooperating with the longitudinal beam connector 3 and two adjusting mechanisms 5 through the longitudinal beam 4, the error of the wire rope groove is compensated, the longitudinal rotation of the longitudinal beam connector 3 is realized, and at the same time, the I-shaped lower hanging part 1 works more stably;

[0046] Through the cooperation of the I-shaped lower hanging part 1, the longitudinal beam connector 3 and the frame 2, the frame 2 can swing slightly longitudinally, increasing the longitudinal working space of the I-shaped lower hanging part 1 and improving the working efficiency.
