Description

Technical Field

[0001] This utility model belongs to the technical field of hanging basket equipment for cantilever beam construction, and specifically relates to a hanging basket main truss traveling system. Background Technology

[0002] A hanging formwork is a specialized piece of equipment designed for cantilever bridge construction, primarily used in the cantilever concrete pouring of prestressed continuous beams and continuous rigid frame bridges. The hanging formwork is anchored and suspended from the already constructed beam segment, providing an aerial platform for the next segment's construction. After completing one segment, the hanging formwork can be moved forward and fixed in place to begin construction of the next segment, repeating this cycle until the cantilever concrete pouring is complete. The hanging formwork mainly consists of a load-bearing structure, a suspension system, a traveling system, and a formwork system.

[0003] Hanging basket structures often use hydraulic jacks for step-by-step jacking or winches for traction. However, their drawbacks are low control precision and difficulty in achieving synchronous movement of the main truss of the hanging basket, which is not conducive to maintaining the stability of the hanging basket's movement and may cause deformation or damage to some components.

[0004] To match the force transmission structure and the length of the cantilever beam segment when the hanging basket moves forward, the screw traction device needs to be installed below the lower chord of the main truss of the hanging basket. The screw traction device and the rear anchor buckle device of the main truss of the hanging basket need to be reasonably arranged. Therefore, it is necessary to further develop a traveling system for the main truss of the hanging basket to better utilize the screw traction device for work coordination and effectively prevent instability and overturning when the hanging basket moves forward.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] This utility model provides a hanging basket main truss traveling system, which aims to solve the technical problems mentioned in the background art.

[0007] To achieve the above objectives, the technical solution of this utility model is as follows:

[0008] A traveling system for a hanging basket main truss includes a track, a front support for the main truss, a lower chord of the hanging basket main truss, a screw jack, a reverse wheel assembly, and a longitudinal fixed beam.

[0009] The track is mounted on the box girder. One end of the lower chord of the main truss of the hanging basket is hinged to the inverted wheel assembly, and the other end is equipped with the front support of the main truss. The front support of the main truss is slidably connected to the track.

[0010] The longitudinal fixed beam is mounted on the track, and the end of the inverted wheel assembly away from the lower chord of the main truss of the hanging basket is slidably connected to the longitudinal fixed beam.

[0011] The screw jack is fixedly installed on the track near the front support of the main truss. One end of the screw on the screw jack is connected to the front support of the main truss, and the other end is connected to the lower chord of the main truss of the hanging basket.

[0012] Preferably, the reverse wheel assembly is provided at one end away from the lower chord of the main truss of the hanging basket, and a wheel groove is provided on the longitudinal fixed beam, with the reverse wheel slidably connected in the wheel groove.

[0013] Preferably, the present invention further includes a track limiting mechanism, which comprises multiple I-beams, a track pressure beam, and multiple prestressed anchoring steel bars.

[0014] Multiple I-beams are spaced apart on the track, and a track pressure beam is provided on the track pressure beam. Multiple prestressed anchoring steel bars are provided on the track pressure beam, and all of the multiple prestressed anchoring steel bars are connected to the box girder.

[0015] Preferably, a vertical plate is provided on the track between the screw jack and the front support of the main truss, and the vertical plate has a through hole for the screw to pass through.

[0016] Preferably, a limiting device is provided at the end of the track away from the reverse wheel assembly.

[0017] Due to the adoption of the above technical solution, the beneficial effects of this utility model are as follows:

[0018] This invention provides a main truss traveling system for a hanging basket. The novel folding, assembled intelligent hanging basket uses a screw jack as the screw traction device. The screw jack is used to horizontally pull the main truss of the hanging basket, realizing the synchronous forward movement of the main truss and the entire hanging basket mechanism. It can also be used in conjunction with the Beidou navigation and positioning system for automated, precise, and intelligent control.

[0027] Example

[0028] like Figures 1 to 5 As shown, a hanging basket main truss traveling system includes a track 1, a main truss front support 2, a hanging basket main truss lower chord 3, a screw jack 4, a reverse wheel assembly 5, and a longitudinal fixed beam 8. The track 1 is set on the box girder 100. One end of the hanging basket main truss lower chord 3 is hinged to the reverse wheel assembly 5, and the other end is provided with the main truss front support 2 at its bottom. The main truss front support 2 is slidably connected to the track 1. The longitudinal fixed beam 8 is set on the track 1. The end of the reverse wheel assembly 5 away from the hanging basket main truss lower chord 3 is slidably connected to the longitudinal fixed beam 8. The screw jack 4 is fixedly set on the track 1 near the main truss front support 2. One end of the screw 41 on the screw jack 4 is connected to the main truss front support 2, and the other end is connected to the hanging basket main truss lower chord 3.

[0029] This utility model uses a screw jack 4 as a screw traction device. The screw jack 4 is used to horizontally pull the main truss of the hanging basket, so as to realize the synchronous forward movement of the main truss of the hanging basket and the entire hanging basket mechanism without the need to add a counterweight. It can also be used in conjunction with the Beidou navigation and positioning system for automated, precise and intelligent control.

[0030] The longitudinal fixed beam 8 in the system can realize the pre-stressing anchorage of the track and the contact fixation of the rear anchor section reverse buckle wheel group; the main truss front support 2 adopts a sled design, and when the hanging basket moves forward, the main truss front support 2 can slide on the top surface of the track 1 through the sled structure.

[0031] In this embodiment, please refer to Figure 3 The reverse wheel assembly 5 is provided with a reverse wheel 51 at the end away from the lower chord 3 of the main truss of the hanging basket. A wheel groove (not shown in the figure) is opened on the longitudinal fixed beam 8, and the reverse wheel 51 is slidably connected in the wheel groove.

[0032] In this embodiment, the present invention also includes a track limiting mechanism 6, which includes multiple I-beams 61, a track pressure beam 62, and multiple prestressed anchoring steel bars 63. The multiple I-beams 61 are spaced apart on the track 1, and a track pressure beam 62 is provided on them. Multiple prestressed anchoring steel bars 63 are provided on the track pressure beam 62, and all the multiple prestressed anchoring steel bars 63 are connected to the box girder 100. The track limiting mechanism 6 can fix and limit the track 1. In specific operation, the track pressure beam 62 and the track 1 can be anchored by connecting the prestressed anchoring steel bars 63 to the box girder 100.

[0033] In this embodiment, please refer to the return. Figure 2 and Figure 3 A vertical plate 7 is provided on the track 1 between the screw jack 4 and the front support 2 of the main truss. The vertical plate 7 has a through hole 71 for the screw 41 to pass through. A limiting device 9 is provided at the end of the track away from the reverse wheel assembly. The limiting device 9 plays the role of limiting the front support 2 of the main truss, preventing the lower chord 3 of the main truss of the hanging basket from leaving the track 1 and causing damage.

[0034] The working principle of this utility model:

[0035] This utility model provides a traveling system for the main truss of a hanging basket. In specific operation, the two ends of the screw 41 of the screw jack 4 are respectively connected to the front support 2 of the main truss and the lower chord 3 of the main truss of the hanging basket. Please refer to [link / reference needed]. Figure 4 and Figure 5 The power source of the screw jack 4 uses the deceleration control of the worm gear mechanism to make the screw 41 move in the horizontal direction, thereby realizing the longitudinal movement of the screw 41 and driving the lower chord of the main truss of the hanging basket to slide on the track 1.

[0036] Before the basket moves forward, the rear anchor of the lower chord 3 of the main truss of the basket is released. Under the action of the basket structure's own weight, the lower chord 3 of the main truss of the basket tilts forward. At this time, the reverse wheel 51 of the reverse wheel group 5 at the rear anchor end is reversed and locked in the wheel groove of the longitudinal fixed beam 8, forming a new rear anchor of the main truss. The screw jack 4 is then started to realize the forward movement of the entire basket mechanism.

[0037] The above description is a detailed description of the preferred embodiments of the present utility model. However, the embodiments are not intended to limit the scope of the patent application of the present utility model. All equivalent changes or modifications made under the technical spirit of the present utility model should fall within the patent scope covered by the present utility model.
