Technical Field

[0001] This utility model relates to the field of concrete diversion technology, specifically a self-propelled box girder web concrete diversion device. Background Technology

[0002] With rapid economic development, especially the large-scale infrastructure construction undertaken to stimulate consumption, the construction industry has experienced unprecedented growth. Box girders are increasingly being used on construction sites. The widespread adoption of box girders in high-speed railways is a natural result of the perfect combination of technological requirements (high rigidity, high stability, and high smoothness) and engineering practices (standardized prefabrication, mechanized erection, high efficiency, and high quality). While meeting the core performance requirements of high-speed rail, it achieves large-scale, high-quality, and high-efficiency construction through industrialized construction methods, and possesses excellent long-term economic benefits and ease of maintenance. Therefore, it has become the undisputed preferred structural form in modern high-speed railway bridge engineering.

[0003] Currently, when pouring concrete for the web of a box girder at the construction site, the concrete slurry splashes onto the web or flange formwork. The slurry splashed onto the formwork will solidify over time, resulting in obvious dry ash, slag inclusions, and pitting on the surface, causing the appearance quality of the finished concrete structure to be substandard. Utility Model Content

[0004] The purpose of this invention is to provide a self-propelled box girder web concrete diversion device to address the shortcomings of the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a self-propelled box girder web concrete diversion device, comprising: a track, which is formed by splicing multiple guide rail frames, the guide rail frame including two parallel fixed plates for fixing at the construction site, the two fixed plates being fixedly connected by a connecting beam, rails being fixedly connected to the fixed plates, and limit grooves being provided on the rails; a self-propelled mechanism, which is assembled to drive the frame to slide on the track, the self-propelled mechanism including the frame and multiple drive wheels, each drive wheel being rotatably connected to the frame, each drive wheel having an annular groove for the rails to be inserted into, and a limit ring being fixedly connected in the annular groove to slide in cooperation with the limit groove; and a diversion box, which is installed on the self-propelled mechanism by a detachable mechanism, the diversion box being wider at the top and narrower at the bottom, the concrete flowing from the wide end of the diversion box to the narrow end of the diversion box.

Each locking unit includes: a guide groove formed on the vehicle frame; a guide strip fixedly connected to the air deflector and capable of engaging with the corresponding guide groove; a locking pin threadedly connected to the vehicle frame; and a locking hole formed on the air deflector.

[0010] Preferably, any two adjacent guide rail frames of each guide rail frame are spliced ​​together by a docking mechanism. The docking mechanism includes a docking groove opened at one end of a fixed plate, and a docking post that docks with the docking groove is fixedly connected to the other end of the fixed plate. During splicing and installation, the docking post on one of the two adjacent guide rail frames is inserted into the corresponding docking groove of the other guide rail frame, and the insertion end of each docking post is hemispherical.

[0019] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0020] Please see Figure 1-6 This utility model provides a self-propelled box girder web concrete diversion device, including a track, a self-propelled mechanism, and a diversion box. The track is formed by splicing multiple guide rail frames 2. The guide rail frame 2 includes two parallel fixed plates 21 for fixing and laying on the construction site. The two fixed plates 21 are fixedly connected by a connecting beam 14. Rails 22 are fixedly connected to the fixed plates 21, and the rails 22 have limit grooves 23. The self-propelled mechanism is assembled to drive the frame 1 to slide on the track. The self-propelled mechanism includes the frame 1 and multiple drive wheels 3. Each drive wheel 3 is rotatably connected to the frame 1. Each drive wheel 3 has an annular groove 4 for the rails 22 to be inserted into. A limit ring 5 that slides and cooperates with the limit groove 23 is fixedly connected in the annular groove 4. The diversion box 7 is installed on the self-propelled mechanism by a detachable mechanism. The diversion box 7 is wide at the top and narrow at the bottom. Concrete flows from the wide end of the diversion box 7 to the narrow end of the diversion box 7. It should be noted that multiple wheels are distributed in a rectangular pattern on the frame 1.

[0021] The self-propelled mechanism also includes a control box 8, which is fixedly connected to the frame 1. The controller inside the control box 8 is electrically connected to the drive source of the drive wheels 3. Under the control of the controller, each drive wheel 3 can drive the frame 1 to move along the length direction of the rail on the corresponding guide rail frame 2.

[0022] It should be noted that the controller and drive wheel 3 inside the control box 8 are common knowledge in the field, and their working principles are well-known technologies. The appropriate model is selected according to the actual use. The control principles of the control box 8 and drive wheel 3 are clear to those skilled in the art, and will not be described in detail here.

[0023] The connecting beam between the two fixed plates 21 includes a crossbeam, a first inclined beam, and a second inclined beam. The setting of the connecting beam enables the track to be laid stably on the construction site, increases the contact area between the track and the construction site, and thus enables the self-propelled mechanism to walk stably on the track.

[0024] A rubber pad is fixedly connected to the circumferential side of the limiting slip ring 5. This increases friction and improves sliding stability.

[0025] In this system, any two adjacent guide rail frames 2 are connected by a docking mechanism. This docking mechanism includes a docking groove 12 on one end of a fixed plate, and a docking post 13 fixedly connected to the other end of the fixed plate to dock with the docking groove 12. The insertion end of each docking post 13 is hemispherical. It should be noted that the diameter of the hemisphere is slightly smaller than the diameter of the docking post 13, and the connection between the hemispherical insertion end and the docking post 13 is chamfered to facilitate smoother insertion of the docking post into the corresponding docking groove 12. Specifically, during assembly, the docking post 13 on one of the two adjacent guide rail frames 2 is inserted into the corresponding docking groove 12 of the other guide rail frame 2, facilitating installation and improving the reusability of the device.

[0026] Specifically, during operation, concrete is first poured into the guide box 7, allowing it to flow from the wide end to the narrow end, thus completing the pouring. The guide box 7 effectively prevents concrete slurry from splashing onto the web or flange formwork, avoiding the formation of noticeable dry ash, slag inclusions, and rough surfaces after solidification, and further ensuring the final concrete structure meets aesthetic standards. Based on this, under the control of the controller in the control box 8, the drive wheels 3, rotatably connected to the frame 1, move along their corresponding guide rails 2, allowing the guide box 7 to synchronously follow the frame 1. The entire process requires only operator intervention, eliminating the need for manual pulling, thus reducing workload and allowing for extended pouring operations. The design of the limiting slip ring 5 and limiting groove 23 prevents the frame 1 from shifting during movement, enabling more precise pouring operations.

[0027] The detachable mechanism includes four locking units 9 arranged in a rectangular pattern. Each locking unit 9 includes: a guide groove 91 formed on the frame 1; a guide strip 92 fixedly connected to the air deflector 7 and capable of engaging with the corresponding guide groove 91; a locking pin 93 threadedly connected to the frame 1; and a locking hole 94 formed on the air deflector 7. The guide groove 91 and guide strip 92 facilitate the installation of the air deflector 7 onto the frame 1, and also facilitate the subsequent alignment of the locking pin 93 with the locking hole 94 to complete the locking operation.

[0028] Each limiting groove has a threaded passage 10, and a threaded tube 11 is fixedly connected to the corresponding locking pin 93. The peripheral side of the threaded tube 11 is threaded with threads that mate with the threads of the threaded passage 10. It should be noted that when the threads on the threaded tube 11 rotate with the threads in the threaded passage 10, the locking pin 93 can be inserted into the locking hole 94, thus completing the locking operation. Therefore, the diameter of the threaded tube 11 is larger than the diameter of the locking pin 93, and the two ends of the threaded passage 10 have slides adapted to the locking pin 93, preventing the locking pin 93 from falling off the frame 1.

[0029] The frame 1 is equipped with multiple cleaning components that correspond one-to-one with each drive wheel 3. Each cleaning component includes a cleaning unit 6 located on the front and rear sides of the corresponding drive wheel 3. The cleaning unit 6 includes a limit rod 61 fixedly connected via an extension frame. The bottom of the limit rod 61 is fixedly connected to a cleaning plate 62 located in the corresponding limit groove 23.

[0030] Each cleaning plate 62 has a first inclined surface 63, which faces the forward direction of the corresponding drive wheel 3.

[0031] It should be noted that a barrier plate 64 is fixedly connected to the limiting rod 61. The barrier plate 64 has two symmetrically arranged guide slopes 65. The inclination direction of the guide slopes 65 is downward and outward from the center of the barrier plate 64.

[0032] Specifically, during the forward movement of the self-propelled mechanism, impurities (such as concrete residue) located in the limiting groove 23 will be cleaned by the corresponding cleaning plate 62 and rolled out of the limiting groove 23 along the first inclined surface 63 and the guide inclined surface, thereby effectively preventing the driving wheels 3 of the self-propelled mechanism from getting stuck during the movement.

[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
