Description

Technical Field

[0001] This utility model belongs to the technical field of transfer track structure, specifically relating to a transfer track for partitioned hoisting by a double tower crane. Background Technology

[0002] In construction industrial park projects, due to varying delivery dates, some buildings are delivered earlier than others. Therefore, the construction company erects tower cranes at corresponding locations on the construction site according to the delivery order, ensuring each crane can handle the construction of at least one or two buildings. However, during construction, the delivery order can sometimes be disrupted for various reasons. Since the tower cranes are already erected and cannot be dismantled and rebuilt, their booms also need to be readjusted to prevent collisions with surrounding crane booms or buildings. While this method still allows construction to proceed, the shortened booms and the sometimes excessive distance of the constructed rebar processing plant beyond the crane's lifting range create difficulties in transporting rebar. Therefore, there is room for improvement. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a transfer track for dual tower cranes to carry steel bars in sections. The transfer track is set between the tower crane and the steel bar processing plant, which can realize the transfer of steel bars from a long distance to the designated tower crane lifting range. It has the advantages of simple handling operation and high transportation efficiency.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A transfer track for sectional hoisting by a double tower crane includes an I-beam rail, a railcar, and a winch. The I-beam rail comprises two parallel I-beams. The railcar includes several roller sets and a base plate. The roller sets are all disposed on the plane of the base plate. The roller sets slide in cooperation with the I-beam rail and support the base plate above the I-beam rail. The winch is disposed at one end of the I-beam rail, and the traction end of the winch is connected to the base plate.

[0006] Furthermore, the roller assembly includes a telescopic shaft and rollers rotatably disposed at both ends of the two telescopic shafts. Each end of the roller shaft is provided with a support rod. An eccentric wheel is rotatably connected to the end of the support rod away from the roller. The shaft of the eccentric wheel is rotatably connected to the pad, and the edge of the eccentric wheel surface is rotatably connected to the support rod.

[0007] Furthermore, the telescopic shaft includes two support rods, a sleeve, and a rigid spring. The two ends of the rigid spring are respectively connected to the ends of the two support rods. The sleeve is fitted between the two support rods. An annular limiting groove is formed on the inner circumference of both ends of the sleeve. The annular limiting groove extends along the length of the sleeve. A limiting ring protrudes from the outer circumferential surface of the support rod near the rigid spring. The limiting ring slides in conjunction with the annular limiting groove, and the annular limiting groove restricts the movement distance of the limiting ring.

[0008] Furthermore, the roller includes an integrally connected side wheel and a support wheel, the side wheel and the support wheel are coaxially arranged, and the diameter of the side wheel is larger than the diameter of the support wheel. In the same roller group, the side wheels of the two rollers are close to each other, and the support wheels of the two rollers are respectively supported on the two I-beams.

[0009] Furthermore, a connecting hook is provided on the end face of the pad near the winch, and the traction end of the winch is a traction rope, the end of which is fixedly connected to the connecting hook.

[0010] Furthermore, several fixing hooks are provided on both opposite sides of the pad.

[0011] Furthermore, the pad has storage grooves on both opposite sides, and the fixing hook is disposed in the storage grooves.

[0012] Furthermore, the number of railcars is multiple, distributed at intervals along the I-beam rails, and square steel is connected between the pads of adjacent railcars.

[0013] This utility model has the following beneficial effects:

[0014] This utility model addresses the issue of situations where, due to temporary changes in construction plans, the length of the tower crane boom cannot be altered, but the distance between the two tower cranes remains constant, and the construction location of the rebar processing plant is relatively fixed. Therefore, it is inevitable that the transported rebar will exceed the lifting range of the tower cranes. By setting up I-beam rails and railcars that slide on these rails, and using a winch to traction a pad to transport the rebar towards the tower cranes, the transported rebar is kept within the lifting range of the two tower cranes. This design offers the advantages of simple handling and efficient transportation. Attached Figure Description

Detailed Implementation

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. Terms such as “upper,” “inner,” “middle,” “left,” “right,” and “one” used in this specification are merely for clarity of description and are not intended to limit the scope of the present invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the present invention.

[0020] This utility model addresses the issue of situations where, due to temporary changes in construction plans, the length of the tower crane boom cannot be altered, but the distance between the two tower cranes remains constant, and the construction location of the rebar processing plant is relatively fixed. Therefore, it is inevitable that the transport of rebar will exceed the lifting range of the tower cranes. This utility model designs a transfer track for zoned lifting by the two tower cranes. One end of the transfer track connects to the rebar processing plant, and the other end is placed within the lifting range of the two tower cranes. Thus, the required rebar can be transported to the end via the transfer track, facilitating normal lifting by the two tower cranes and overcoming the problem of the tower cranes exceeding their lifting range.

[0021] The following further describes the structure of the transfer track for the dual-tower crane's zoned hoisting of this utility model:

[0022] A transfer track for zoned lifting by a dual tower crane, such as Figures 1 to 3 As shown, the system includes an I-beam rail 1, a railcar 2 that slides on the I-beam rail 1, and a winch 3. The I-beam rail 1 includes two parallel I-beam bars 11. The railcar 2 includes several roller sets 5 and a base plate 4. The roller sets 5 are evenly distributed on the bottom surface of the base plate 4, and the roller sets 5 slide in contact with the I-beam rail 1, supporting the base plate 4 above the I-beam rail 1. The winch 3 is an electric winch 3, located at the end of the I-beam rail 1 near the tower crane, and its traction end is connected to the base plate 4. Therefore, the reinforcing bars can be placed on the base plate 4 of the railcar 2, and then transported to the lifting range of the double tower cranes by the traction action of the winch 3, so that the tower cranes can normally lift the required reinforcing bars, while also having the advantages of convenience and efficiency in transportation.

[0023] The number of railcars 2 is multiple, distributed at intervals along the I-beam rail 1. Square steel 44 is connected between the pads 4 of adjacent railcars 2, which can increase the space for holding steel bars, so as to facilitate the handling of more steel bars at one time.

[0024] In this embodiment, in order to improve the stability of steel bar transportation, a corresponding device is set on the pad 4 to temporarily fix the steel bar. The device is described as follows: a storage groove 41 is provided on both opposite sides of the pad 4. A fixing hook 43 is provided on the inner wall of the storage groove 41. The fixing hook 43 is used to tie the connecting rope, so as to temporarily tie the steel bar placed on the pad 4 with the connecting rope to improve transportation stability.

[0025] In this embodiment, a connecting hook 42 is provided on the end face of the pad 4 near the winch 3. The traction end of the winch 3 is a traction rope, and the end of the traction rope is fixedly connected to the connecting hook 42. Therefore, the winch 3 can pull the railcar 2 towards the tower crane by continuously winding the traction rope.

[0026] In this embodiment, since the operating track is a temporary structure and the ground is inevitably uneven, the parallelism of the two I-beams 11 of the constructed I-beam track 1 may have some deviation. Therefore, in order to improve the stability of the connection between the track car 2 and the I-beam track 1, the roller assembly 5 of the track car 2 is optimized as follows: the roller assembly 5 includes a telescopic shaft and rollers 54 rotatably disposed at both ends of the two telescopic shafts. Support rods 55 are provided at both ends of the rotating shaft of the rollers 54. An eccentric wheel 56 is rotatably connected to the end of the support rod 55 away from the roller 54. The rotating shaft of the eccentric wheel 56 is rotatably connected to the pad 4, and the wheel surface edge of the eccentric wheel 56 is rotatably connected to the support rod 55. Therefore, by setting support rods 55 and eccentric wheels 56 on the rollers 54 at both ends of the telescopic shaft, when the two I-beams 11 of the I-beam track 1 are not parallel, the self-adjustment function of the eccentric wheels 56 can be used to make the rollers 54 and the I-beams fit well together, thereby improving the good and stable fit between the roller assembly 5 and the I-beam track 1.

[0027] To limit the telescopic movement of the telescopic shaft and prevent it from detaching from the I-beam rail 1, the telescopic shaft includes two support rods 51, a sleeve 52, and a rigid spring 53. The two ends of the rigid spring 53 are connected to the ends of the two support rods 51, respectively. The sleeve 52 is fitted between the two support rods 51. Annular limiting grooves 521 are formed on the inner circumference of both ends of the sleeve 52, extending along the length of the sleeve 52. A limiting ring 511 protrudes from the outer circumference of the support rod 51 near the rigid spring 53, and the limiting ring 511 slides into the annular limiting groove 521, limiting its movement. The rigid spring 53 is compressed within the sleeve 52, causing the telescopic shaft to tend to extend outwards. This ensures that the roller 54 always maintains good contact with the I-beam rail 11, thereby improving the stability of the railcar 2 in transporting reinforcing bars on the I-beam rail.

[0028] Since the rollers 54 at both ends of the telescopic shaft engage well with the I-beams 11 through outward expansion force, the structure of the rollers 54 is described in detail below: The rollers 54 include an integrally connected side roller 541 and a support roller 542. The side roller 541 and support roller 542 are coaxially arranged, and the diameter of the side roller 541 is larger than the diameter of the support roller 542. In the same roller group 5, the side rollers 541 of the two rollers 54 are close to each other, and the support rollers 542 of the two rollers 54 are respectively supported on the two I-beams 11. Therefore, under the outward expansion force of the telescopic shaft, the rollers 54 utilize the restraining effect of the side rollers 541 to ensure a good fit between the rollers 54 and the I-beams 11, thereby improving connection stability.

[0029] In summary, this utility model addresses the issue that at construction sites, due to temporary changes in plans, the length of the tower crane boom cannot be altered, but the distance between the two tower cranes remains unchanged, and the construction location of the steel reinforcement processing plant is relatively fixed. Therefore, it is inevitable that the steel reinforcement will exceed the lifting range of the tower crane when being transported. By setting up an I-beam rail 1 and a railcar 2 that slides on the I-beam rail, and using the traction of a winch 3 to drive the pad 4 towards the tower crane, the steel reinforcement is transported within the lifting range of the two tower cranes. Therefore, it has the advantages of simple handling and efficient transportation.

[0030] The embodiments of this utility model are not limited thereto. Based on the above content of this utility model, using ordinary technical knowledge and conventional means in the field, without departing from the basic technical idea of ​​this utility model, this utility model can also be modified, replaced or combined in various other forms, all of which fall within the scope of protection of this utility model.
