Detailed Implementation
[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0026] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0027] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0028] In the description of this utility model, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product is usually placed during use, they are only for the convenience of describing this utility model and simplifying the description, and 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 of this utility model.
[0029] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.
[0030] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.
[0031] The following describes in detail, with reference to the accompanying drawings, the specific structure of a culvert template trolley 1 provided by this utility model and the corresponding technical effects it brings.
[0032] Please refer to Figures 1-3 The culvert formwork trolley 1 provided in this embodiment of the utility model includes a formwork body 100, a lifting base 200, and a traveling mechanism 300. The lifting base 200 is installed at the bottom of the formwork body 100 and is used to support the formwork body 100 and to drive the formwork body 100 to move in the height direction. The traveling mechanism 300 is detachably installed at the bottom of the formwork body 100.
[0033] Understandably, when the traveling mechanism 300 needs to be installed on the formwork body 100, the lifting base 200 can be used to lift the formwork body 100 onto the platform, causing the bottom of the formwork body 100 to move upwards and off the ground. This allows workers to install the traveling mechanism 300 onto the bottom of the formwork body 100. Then, the lifting base 200 can be used to lower the formwork body 100 until the traveling mechanism 300 is used to support the formwork body 100, at which point the traveling mechanism 300 can move the formwork body 100. When the traveling mechanism 300 needs to be removed from the bottom of the formwork body 100, the lifting base 200 can be used to lift the formwork body 100 onto the platform until the traveling mechanism 300 is off the ground, allowing workers to remove the traveling mechanism 300 from the formwork body 100. Then, the lifting base 200 can be used to lower the formwork body 100.
[0034] Understandably, the non-removable design of the template trolley makes it difficult to access and inspect the key components of the traveling mechanism 300, increasing the difficulty of daily maintenance and troubleshooting. If certain components of the traveling mechanism 300 (such as bearings, bushings, etc.) are damaged, the entire template trolley must be disassembled for replacement, consuming a lot of time and manpower. Once the non-removable traveling mechanism 300 is in motion, it may experience jamming or instability, resulting in poor adaptability and potentially slowing down the construction progress. In contrast, in this embodiment, because the traveling mechanism 300 is detachable, when the traveling mechanism 300 is damaged, it is easy for operators to disassemble and replace it with a new one, allowing the trolley to continue moving. This provides higher adaptability and facilitates maintenance.
[0035] Understandably, the detachable walking mechanism 300 allows the formwork trolley to more easily adapt to different construction sites and terrain conditions. For example, in narrow or complex environments, the walking mechanism 300 can be disassembled, the formwork trolley can be moved to a designated location by other means (such as hoisting), and then the walking mechanism 300 can be reinstalled.
[0036] Optionally, the lifting base 200 can be a bottom support screw or a hydraulic drive component. Understandably, when the lifting base 200 is a bottom support screw, the bottom support screw includes a base and a screw. The base is fixedly connected to the bottom of the template body 100. The base has a threaded hole for the screw to pass through. When the traveling mechanism 300 is not installed on the template body 100, the screw does not extend out of the threaded hole. When it is necessary to raise the template body 100 too high, the screw is rotated so that the screw extends out of the threaded hole and is supported on the ground until the template body 100 is raised too high.
[0037] When the lifting base 200 is a hydraulic drive, the hydraulic drive includes a drive and a base connected together. The base is fixedly connected to the bottom of the template body 100. The drive end of the drive can move in the height direction and the drive end faces the ground. When it is necessary to raise the template body 100, the drive end of the hydraulic drive can move towards the ground until the template body 100 is lifted in the opposite direction by the drive end.
[0038] Optionally, in this embodiment, the walking mechanism 300 includes multiple walking wheels and a walking drive component (not shown). The multiple walking wheels are arranged in a rectangular array to facilitate the multiple walking wheels supporting the template body 100. The walking drive component is used to drive the walking wheels to rotate so that the template body 100 can walk.
[0039] The walking mechanism 300 includes multiple axle mounting frames that correspond one-to-one with multiple walking wheels. The axle mounting frames are detachably installed on the bottom of the template body 100. Each axle mounting frame is equipped with a walking wheel, and the rotation axes of the multiple walking wheels are parallel.
[0040] The wheel and axle mounting bracket facilitates the installation and removal of the wheels by operators. The rotation axes of multiple wheels are parallel to ensure that the wheels can move in the preset direction without easily deviating.
[0041] In this embodiment, there are four walking wheels, which are arranged in pairs. The two groups of walking wheels are arranged at intervals along the front-back direction of the template body 100. The two walking wheels in each group are arranged at intervals along the width direction of the template body 100, and the axes of the two groups of walking wheels are coaxial. The walking drive is used to drive one of the two groups to rotate.
[0042] Understandably, by setting up two sets of walking wheels, the template body 100 can move along its own front-to-back direction via the walking wheels.
[0043] Optionally, in order to further ensure the stability of the template body 100 during movement and to prevent the template body 100 from deviating during movement, the walking mechanism 300 also includes a walking track that rolls with the walking wheels, and the walking track is installed on the ground.
[0044] The top of the formwork body 100 has a construction platform 140, which has a construction surface and a protective railing installed on it. Optionally, the distance between the protective railing and the construction surface is greater than or equal to 1.2m. Understandably, the installation of the protective railing ensures the safety of workers on the construction surface during construction operations.
[0045] Of course, in some other embodiments, the distance between the protective fence and the construction platform can also be less than 1.2m.
[0046] The formwork body 100 includes a first outer formwork 110, an inner formwork 130, and a second outer formwork 120 installed sequentially along its width. The inner formwork 130 is detachably connected to the first outer formwork 110 and the second outer formwork 120 on both sides. The first outer formwork 110, the inner formwork 130, and the second outer formwork 120 are all detachably connected to the construction platform 140. Understandably, since the first outer formwork 110, the inner formwork 130, and the second outer formwork 120 are all detachably connected to the construction platform 140, it facilitates assembly and disassembly by workers.
[0047] The first outer template 110 and the inner template 130 can be connected by threaded fasteners, and the inner template 130 and the second outer template 120 can also be detachably connected by threaded fasteners.
[0048] The top of the inner formwork 130 is connected to the bottom of the construction platform 140 by threaded fasteners, which ensures the strength of the connection between the inner formwork 130 and the construction platform 140. The bottom of the construction platform 140 is equipped with a first hoisting component 150 and a second hoisting component 160 arranged at intervals along its width direction. The first hoisting component 150 is detachably connected to the first outer formwork 110, and the second hoisting component 160 is detachably connected to the second outer formwork 120.
[0049] In detail, the inner formwork 130 includes an inner formwork base frame 131, an inner formwork support 132, and an inner formwork top frame 133. The two ends of the inner formwork support 132 along the height direction are detachably connected to the inner formwork base frame 131 and the inner formwork top frame 133, respectively. The lifting base 200 and the traveling mechanism 300 are installed on the side of the inner formwork base frame 131 away from the inner formwork support 132. The inner formwork top frame 133 is used to detachably connect to the construction platform 140.
[0050] Understandably, the inner mold support 132 is detachably connected to the inner mold base frame 131 and the inner mold top frame 133 at both ends along the height direction, and the inner mold top frame 133 is detachably connected to the construction platform 140, so as to facilitate the assembly and disassembly of the inner mold 130 by the operators. The inner mold support 132 can also be connected to the inner mold base frame 131 and the inner mold top frame 133 at both ends along the height direction via threaded fasteners, and the inner mold top frame 133 can also be detachably connected to the construction platform 140 via threaded fasteners.
[0051] The inner mold support 132 includes a vertical support 1321 extending along the height direction and a horizontal support 1322 extending along the horizontal direction. The horizontal support 1322 is detachably connected to the vertical support 1321 and is located between the inner mold base frame 131 and the inner mold top frame 133. The inner mold support 132 also includes an inclined support 1323. One end of the inclined support 1323 is detachably connected to the vertical support 1321, and the other end of the inclined support 1323 is detachably connected to the horizontal support 1322 or the inner mold base frame 131. The structural strength of the inner mold support 132 can be improved by setting the inclined support 1323.
[0052] It should be noted that the aforementioned detachable connection can be understood as a connection via threaded fasteners, which may include bolts and nuts.
[0053] In summary, the culvert formwork trolley 1 provided in this embodiment of the present invention includes a formwork body 100, a lifting base 200, and a traveling mechanism 300. The lifting base 200 is installed at the bottom of the formwork body 100, and is used to support the formwork body 100 and to drive the formwork body 100 to move in the height direction. The traveling mechanism 300 is detachably installed at the bottom of the formwork body 100. The detachable traveling mechanism 300 allows the formwork trolley to more easily adapt to different construction sites and terrain conditions. For example, in narrow or complex environments, the traveling mechanism 300 can be disassembled, and the formwork trolley can be moved to a designated position by other means (such as hoisting) before the traveling mechanism 300 is reinstalled.
[0054] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
