Description

Technical Field

[0001] This utility model relates to the field of cantilever casting construction technology, and in particular to an anti-overturning device. Background Technology

[0002] With the development of the industry and the continuous progress and improvement of cantilever construction, cantilever construction has now become an extremely effective construction method for medium and large span bridges.

[0003] Cantilever construction using hanging baskets, also known as the Dividak method, is a construction method for cantilever casting of medium- and long-span bridges without the need for full-span scaffolding or large hoisting equipment. With the continuous development of the construction industry, cantilever casting using hanging baskets has been continuously improved. By the 1970s, 80% of bridges with spans greater than 100m were constructed using this method. Currently, hanging baskets have evolved into various types based on the shape of the main truss and the construction location, including parallel truss hanging baskets, triangular composite beam hanging baskets, bowstring hanging baskets, cable-stayed hanging baskets, and triangular truss hanging baskets, among others.

[0004] During construction, the hanging basket needs to move according to the needs of the project. During the movement of the hanging basket, it is difficult to guarantee the stability of the entire hanging basket by relying solely on the reverse wheels. Once a safety accident occurs, the economic losses in terms of personnel and materials will be huge. In severe cases, the accident may lead to long-term work stoppage and the economic losses will be incalculable. Utility Model Content

[0005] The main objective of this invention is to provide an anti-tipping device that overcomes the above-mentioned technical problems.

[0006] To achieve the above objectives, the present invention proposes the following technical solution:

[0007] An anti-tipping device, comprising:

[0008] Anti-overturning support, located at the upper end of the device, with the upper end connected to the cantilever casting basket;

[0009] Anti-overturning baffles are connected to the lower end of the anti-overturning support and are symmetrically arranged below the anti-overturning support;

[0010] Anti-tipping chocks are provided on the inner sides of the two anti-tipping baffles that are close to each other.

[0011] Furthermore, the anti-overturning support has an upward-opening groove in the middle, the width of which is just enough to accommodate the longitudinal beam at the bottom of the cantilever casting basket.

[0012] Furthermore, the bottom of the anti-overturning support is symmetrically provided with two receiving spaces, which are just the right size for the anti-overturning baffle to be inserted vertically.

[0013] Furthermore, the distance between the two anti-overturning baffles is slightly greater than the track width of the cantilever casting basket.

[0014] Furthermore, the anti-overturning support and the cantilever casting basket are detachably connected.

[0015] Furthermore, the anti-overturning support and the cantilever casting basket are connected and fixed by a first pin.

[0016] Furthermore, the anti-overturning baffle and the anti-overturning support are detachably connected.

[0017] Furthermore, the anti-overturning baffle and the anti-overturning support are connected and fixed by a second pin.

[0018] Furthermore, the anti-rollover wheel and the anti-rollover baffle are connected by bolts.

[0019] According to another aspect of this application, a cantilever casting basket is provided, which includes the aforementioned anti-tipping device.

[0020] The anti-tipping device and cantilever casting basket of this utility model can solve the problem that the existing hanging basket cannot guarantee the stability of the entire hanging basket by relying solely on its own pair of anti-locking wheels during construction, resulting in a high risk of tipping over during construction. It has the advantages of structural stability, extended hanging basket life, low maintenance cost, and increased construction safety, which greatly improves the economic benefits brought about by the reduction of safety accidents.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0028] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0029] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0030] The following is for reference. Figs. 1 to 3 The present invention will be further described below:

[0031] An anti-tipping device, comprising:

[0032] Anti-overturning support 1 is located at the upper end of the device, and the upper end is connected to the cantilever casting basket. The anti-overturning support 1 and the cantilever casting basket are detachably connected.

[0033] Anti-overturning baffle 2 is connected to the lower end of anti-overturning support 1 and is symmetrically arranged below anti-overturning support 1. There are two symmetrically arranged receiving spaces 12 at the bottom of anti-overturning support 1, which are just the right size to allow anti-overturning baffle 2 to be inserted vertically. The distance between the two anti-overturning baffles 2 is slightly larger than the width of the track 5 of the cantilever casting basket. The anti-overturning baffle 2 and anti-overturning support 1 are detachably connected.

[0034] In this embodiment, the anti-overturning baffle 2 and the anti-overturning support 1 are connected and fixed by a second pin 21, the diameter of which is 50mm.

[0035] Anti-tipping wheel 3, anti-tipping wheel 3 is provided on the inner side of the two anti-tipping baffles 2 that are close to each other, and the anti-tipping wheel 3 is connected to the anti-tipping baffle 2 by bolt 31.

[0036] The anti-overturning support 1 has an upward-opening groove 11 in the middle position, the width of which is just enough to accommodate the longitudinal beam 4 at the bottom of the cantilever casting basket. The anti-overturning support 1 and the cantilever casting basket are connected and fixed by a first pin 13. The connection by the first pin 13 can facilitate the disassembly of the anti-overturning support 1 and the cantilever casting basket. They can be disassembled according to different construction needs, while ensuring the connection strength between the two.

[0037] In this embodiment, the diameter of the first pin 13 is 100mm.

[0038] According to another aspect of this application, a cantilever casting basket is provided, which includes the aforementioned anti-overturning device. By setting the anti-overturning device on the cantilever casting basket, the stress points of the cantilever casting basket are increased, and the cantilever casting basket can be better supported when it tilts, thus ensuring the safety of personnel and equipment.

[0039] The use of anti-overturning devices makes cantilever casting formwork significantly superior to traditional formwork construction in terms of safety, stability, and economic benefits. Compared to traditional formwork construction, the addition of anti-overturning devices significantly increases the safety of formwork construction, especially during the formwork's movement. It increases the tension between the rear anchor and the travel track, ensuring the safety of the formwork's movement and effectively extending its service life. The newly added anti-overturning devices can effectively bear a portion of the tension on the anti-locking rollers, reducing stress damage to the anti-locking roller assembly.

[0040] The use of anti-overturning devices for hanging baskets effectively reduces the occurrence of hanging basket safety accidents and saves personnel and material losses caused by hanging basket construction accidents.

[0041] In one optional embodiment, high-precision sensors are installed on key parts such as the main truss, anti-overturning components, and travel track of the cantilever casting formwork to monitor parameters such as the inclination, displacement, and stress of the formwork in real time. Construction personnel can remotely monitor the status of the formwork and obtain construction data in real time through mobile devices such as mobile phones and tablets, enabling them to promptly detect abnormal data in the equipment and deal with potential dangers as early as possible.

[0042] In one optional embodiment, the cantilever casting basket is incorporated into an intelligent control system: based on embedded technology and a cloud computing platform, an intelligent control system is designed to process and analyze sensor data in real time, determine whether the basket is in a safe state, and automatically adjust the tension or angle of the anti-overturning components as needed.

[0043] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0044] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0045] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0046] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
