Abstract
Description
Technical Field
[0001] This utility model belongs to the field of building construction technology, and more specifically, it relates to a hanging basket sling adjustment mechanism. Background Technology
[0002] In bridge construction, hanging basket construction is a commonly used construction method, especially suitable for the construction of long-span prestressed concrete beam bridges. As a movable construction platform, the hanging basket is suspended from the already poured beam segment by slings, providing working space and support for the subsequent pouring of beam segments.
[0003] Traditional hanging basket sling devices use screw jacks installed between the slings and the crossbeam. Rotating the screw of the jacks adjusts the lifting and lowering of the slings. Screw jacks have a large load-bearing capacity and good adjustment accuracy. However, the height of the traditional support beam needs to be adjusted manually, which is cumbersome and slow. When the bottom of the support beam is too high, the stability and safety of the overall support will decrease, making it inconvenient for workers to operate. Utility Model Content
[0004] To address the aforementioned technical problems, this utility model provides a hanging basket sling adjustment mechanism. This mechanism solves the technical problems in the prior art where the height of the traditional support beam needs to be adjusted manually, which is cumbersome and slow. Furthermore, when the bottom of the support beam is raised too high, the overall stability and safety of the support decrease, making it inconvenient for workers to carry out construction work.
[0005] The purpose and function of this utility model's hanging basket strap adjustment mechanism are achieved through the following specific technical means:
[0006] A basket suspension adjustment mechanism includes two sets of basket crossbeams;
[0007] The tops of the crossbeams of both sets of hanging baskets are connected to the adjustment assembly;
[0008] The adjustment assembly includes a pad beam, and each of the two sets of hanging basket crossbeams is equipped with a rotatable adjusting screw. The pad beam is movable up and down and connected to the two sets of adjusting screws. A lifting strap is threaded through the pad beam, and multiple sets of lifting strap holes are equally spaced on the lifting strap. Two sets of semi-circular support seats are provided on the top of the pad beam, and a working pin is provided between the two sets of semi-circular support seats. One end of the working pin passes through one of the sets of lifting strap holes.
[0009] In a preferred embodiment, two sets of nuts are provided inside the pad beam, and the two sets of nuts are respectively sleeved on the two sets of adjusting screws.
[0010] In a preferred embodiment, a pad is provided on the top of the hanging basket beam, and the bottom ends of the two sets of adjusting screws are rotatably connected to the two sets of pads respectively.
[0011] In a preferred embodiment, both sets of the hanging basket beams are provided with spiral tops, and the two sets of spiral tops are located on both sides of the sling and are vertically distributed.
[0012] In a preferred embodiment, both sets of spiral tops are provided with top blocks, and the tops of both sets of top blocks are connected to tool pins.
[0013] In a preferred embodiment, one end of the tool pin passes through the sling.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] 1. With the setting of two sets of adjusting screws, when installing this device, the operator only needs to turn the adjusting screws and nuts on them to adjust the height of the pad beam. Then, the lifting belt is pulled by the working pin, making the height adjustment process of the pad beam more efficient and smooth, effectively improving the efficiency of construction operations.
[0016] 2. With the two sets of screw jacks, the sling will be under stress when using the device, making it impossible to adjust the height of the pad beam by rotating the adjusting screw. At this time, insert the tool pin at the top of the screw jack into the sling hole, pull out the working pin, and the screw jack can then drive the sling to adjust its height. After the sling height is adjusted, adjust the height of the semi-circular support by rotating the adjusting screw, so that the working pin on the semi-circular support can be aligned with the sling hole and inserted, thereby completing the adjustment of the pad beam height.

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.
[0023] Example:
[0024] As attached Figure 1 To be continued Figure 3 As shown:
[0025] This utility model provides a hanging basket sling adjustment mechanism, which includes two sets of hanging basket crossbeams 11 as basic load-bearing structures, and the tops of the two sets of hanging basket crossbeams 11 are connected to the adjustment component.
[0026] The adjustment assembly includes a pad beam 20, and two sets of hanging basket crossbeams 11, each topped with a rotatable adjusting screw 18. The pad beam 20 is vertically movable and connected to the two sets of adjusting screws 18. A sling 16 is threaded through the pad beam 20, and its position is controlled by height adjustment. Multiple sling holes are equidistantly arranged on the sling 16. Two sets of semi-circular support seats 21 are located at the top of the pad beam 20, and a working pin 19 is positioned between the two sets of semi-circular support seats 21. One end of the working pin 19 passes through one set of sling holes, and its engagement with the sling hole fixes the position of the sling 16. During installation, the adjusting screw 18 engages with a nut 14. The operator only needs to rotate the adjusting screw 18 to move the pad beam 20 axially along the adjusting screw 18 using the thread transmission principle, thereby adjusting the height of the pad beam 20. The working pin 19 then pulls the sling 16, adjusting its height.
[0027] Two sets of nuts 14 are installed inside the pad beam 20. The two sets of nuts 14 are respectively fitted onto two sets of adjusting screws 18 to ensure the stability of the pad beam 20 during the adjustment process. In order to enhance the connection stability between the adjusting screws 18 and the hanging basket crossbeam 11, a pad plate 22 is provided on the top of the hanging basket crossbeam 11. The bottom ends of the two sets of adjusting screws 18 are rotatably connected to the two sets of pad plates 22 respectively, which increases the contact area between the adjusting screws 18 and the hanging basket crossbeam 11, disperses the load generated during the adjustment process, reduces the phenomenon of local stress concentration, and improves the load-bearing capacity of the entire structure.
[0028] Both sets of hanging basket beams 11 are equipped with spiral tops 12, which are located on both sides of the sling 16 and are vertically distributed. Both sets of spiral tops 12 are equipped with top blocks, and the tops of both top blocks are connected to tool pins 15, one end of which passes through the sling 16.
[0029] When the sling 16 is subjected to force that prevents the height of the pad beam 20 from being adjusted by rotating the adjusting screw 18, the operator can insert the tool pin 15 at the top of the screw jack 12 into the sling hole. The screw jack 12 will then drive the top block to move up and down, thereby adjusting the height of the sling 16. This ensures that the height of the sling 16 can be adjusted under different working conditions, improving the environmental adaptability of the device.
[0030] When using this device, if the sling 16 is under stress and cannot be adjusted by adjusting the screw 18, first insert the tool pin 15 at the top of the screw jack 12 into the corresponding sling hole on the sling 16, pull out the working pin 19, and release the fixing of the pad beam 20 to the sling 16. Then, operate the screw jack 12 to drive the sling 16 to adjust its height. After the height of the sling 16 is adjusted, rotate the adjusting screw 18 again to drive the pad beam 20 and the semi-circular support 21 to move up and down along the adjusting screw 18, so that the working pin 19 on the semi-circular support 21 can be aligned with the target sling hole and inserted, re-establishing the connection between the pad beam 20 and the sling 16, and completing the height adjustment of the pad beam 20. This makes the height adjustment process of the pad beam 20 smoother, reduces the labor intensity of the operator, and improves the efficiency of the construction operation.
