Description

Technical Field

[0001] This utility model relates to the field of channel construction technology, specifically to a concrete construction template trolley for channel sidewalls. Background Technology

[0002] Canals are facilities used in water conservancy projects to transport water resources. They typically include the canal bottom, side walls, and related supporting facilities, playing a vital role in guiding water flow and ensuring the rational allocation and utilization of water resources. The main construction techniques used in the artificial construction of canals are cast-in-place and precast concrete. When using the cast-in-place method, the traditional method of pouring concrete for the canal side walls often requires the erection of scaffolding to provide support for the formwork. If the canal is long, there will be a large amount of work involved in the installation, dismantling, and transportation of formwork and support systems. These operations are highly dependent on manual labor, which is not only labor-intensive but also inefficient, severely hindering the construction progress.

[0003] In this regard, Chinese Patent No. CN220598350U discloses a large mobile steel mold for a channel, including a portal frame, a slide rail, inner and outer templates, cantilever, support rod, tie rod and rolling structure. The entire mobile steel mold uses the portal frame as the main body and moves on the slide rail using bottom rollers. The top two ends of the portal frame are provided with cantilever, the outer template is connected to the cantilever through the tie rod, and its bottom end moves through the rolling structure. The inner template is connected to the portal frame through the support rod. The aforementioned movable steel formwork for channels has the following limitations: The outer formwork is cantilevered to the top of the portal frame via tie rods. This tie rod connection makes it difficult to flexibly adjust the outer formwork vertically, thus limiting its adaptability to construction of channels at different heights. The inner formwork is primarily supported by support rods on both sides of the portal frame. During concrete pouring, force is transmitted to the portal frame through the formwork and support rods. To ensure concrete quality and prevent formwork displacement, the portal frame requires high rigidity, resulting in higher manufacturing costs. The inner formwork is fixed to the support rods using pin connections. Pins can only be inserted after the pin holes are coaxial. Due to the numerous connection points, this process requires multiple people and high precision, making construction cumbersome and time-consuming. The inner formwork is fixed to numerous support rods. If the connection between the inner formwork and support rods is maintained during demolding, mobility is limited, making demolding difficult. Removing the connection between the inner formwork and some support rods is time-consuming due to the numerous connection points and complex connection methods. Utility Model Content

[0004] To address the shortcomings of existing formwork trolleys for concrete construction of channel sidewalls, this utility model provides a formwork trolley for concrete construction of channel sidewalls. This formwork trolley can transport formwork in both vertical and horizontal directions through a hoisting device, allowing for flexible adjustment of the formwork position. This not only improves work efficiency but also adapts to the construction needs of channels of different sizes.

[0005] To achieve the above-mentioned technical objectives, this utility model is implemented through the following technical solution:

[0006] A concrete formwork trolley for channel sidewall construction, comprising:

[0007] Guide rails, which are laid along the channel direction;

[0008] The trolley body includes a traveling mechanism, a lifting frame, and a hoisting device;

[0009] The walking mechanism is connected to the bottom of the trolley body and moves along the guide rail. The hangers are arranged in pairs and connected to the top of the trolley body. Both ends of the hangers extend towards the side wall of the channel.

[0010] Multiple sets of hoisting devices are arranged in pairs and distributed at both ends of the hanger. Adjacent hoisting devices on the same side move along the hanger through a translation mechanism, driving the inner and outer formwork to the position of the channel sidewall, thus completing the pouring of the channel sidewall.

[0011] In this scheme, guide rails laid along the channel direction allow the traveling mechanism at the bottom of the trolley to move along the rails, enabling convenient vertical movement and positioning of the formwork. Pairs of hangers are installed on the top of the trolley and extend towards the channel sidewalls, providing stable support for formwork hoisting. Multiple hoisting devices are distributed at both ends of the hangers, and adjacent hoisting devices on the same side can move along the hangers via a translation mechanism, enabling precise movement of the inner and outer formwork to the channel sidewall position, facilitating horizontal adjustment of the formwork. Therefore, this scheme not only facilitates adjusting the formwork position to adapt to the construction needs of channels of different sizes, but also offers flexible operation, reducing manual installation, dismantling, and transportation of the formwork and support system, improving work efficiency, and ensuring the smooth progress of channel sidewall pouring construction.

[0012] As a further technical solution for the template trolley, the hanger includes a crossbeam, and the translation mechanism includes rollers and wheel groove boxes;

[0013] The crossbeams are arranged in pairs and connected to the top of the trolley body. Both ends of the crossbeams extend towards the sidewall of the channel, and the crossbeams have an I-shaped cross section.

[0014] The wheel groove box forms sliding matching cavities on the left and right sides of the crossbeam, and the roller is disposed in the sliding matching cavity. By driving the roller to move along the crossbeam, the hoisting device is moved laterally.

[0015] In this design, the crossbeams are arranged in pairs and connected to the top of the trolley body, extending towards the channel sidewalls at both ends, providing a stable lateral support foundation for the entire structure. Their I-beam cross-section design also increases structural strength. Wheel groove boxes form sliding matching cavities on both sides of the crossbeams, housing the rollers. This design allows for smoother, more precise, and stable lateral movement of the hoisting device. The lateral movement of the hoisting device is driven by moving the rollers along the crossbeams, simplifying operation and saving effort. This effectively improves the accuracy of horizontal position adjustment during formwork hoisting, better adapting to the precise positioning requirements of formwork during different channel sidewall constructions, and further enhancing the practicality and construction efficiency of the formwork trolley.

[0016] As a further technical solution for the template trolley, the translation mechanism also includes a hand-operated hoist, one end of which is connected to the wheel groove box, and the other end of which is connected to the template via a hook.

[0017] In this solution, the hand-operated hoist provides reliable and convenient vertical adjustment for formwork hoisting. One end connects to the wheel well box, and the other end is connected to the formwork via a hook. Operators can easily raise and lower the formwork vertically by pulling the hoist's chain. This method is not only simple and labor-saving, but also allows for precise control of the formwork's vertical position, making installation and adjustment more efficient and accurate. In channel sidewall concrete construction, the formwork can be quickly hoisted to the required height and precisely positioned, significantly reducing manpower and construction time. It also improves the quality and stability of formwork installation, ensuring smooth construction and further enhancing the practicality and efficiency of the entire formwork trolley.

[0018] As a further technical solution for the template trolley, the trolley body also includes a pair of supports, the supports being spaced apart at the upper end of the traveling mechanism, and the crossbeams being connected to the top of the corresponding supports respectively.

[0019] The brackets are connected and supported by an upper crossbar and a lower crossbar.

[0020] In this design, paired supports are spaced apart at the top of the traveling mechanism, providing a stable vertical support structure for the trolley body and ensuring the stability of the entire formwork trolley during operation and work. Crossbeams connect to the top of the supports, forming a stable overall frame between the hanger and the supports, effectively distributing the load generated when the hoisting device transports the formwork and enhancing the structure's load-bearing capacity. The supports are connected by upper and lower crossbars, further reinforcing the support system and forming a stable spatial structure, improving the trolley body's resistance to deformation. During the concrete construction of the channel sidewall, this design better resists external forces such as lateral pressure generated during concrete pouring, ensuring the structural safety of the formwork trolley and guaranteeing smooth construction.

[0021] As a further technical solution for the template trolley, a stiffening plate is connected between the upper crossbar and the lower crossbar, and a stiffening plate is connected between the lower crossbar and the traveling mechanism.

[0022] In this design, stiffening plates are connected between the upper and lower crossbars, and between the lower crossbar and the traveling mechanism, effectively enhancing the stability and integrity of the structure.

[0023] As a further technical solution for the template trolley, the stiffening plates are arranged in pairs, and the paired stiffening plates are inclined to form a triangular structure.

[0024] In this design, the stiffening plates create a more stable triangular structure within the support system. This triangular structure offers excellent stability and better resistance to external forces, such as the pressure and vibration generated during concrete pouring in channel sidewall construction. Simultaneously, it enhances the connection strength between the supports, crossbars, and traveling mechanism, improving their collaborative working ability, reducing the risk of localized structural deformation or damage, and ensuring the formwork trolley maintains stable and reliable operation in complex construction environments. This also improves the durability of the formwork trolley and extends its service life.

[0025] As a further technical solution for the template trolley, a pair of support screws are provided on the lower crossbar, and the two ends of the pair of support screws are pressed against the inner template located at the side wall of the channel.

[0026] In this scheme, a bracing rod is installed on the lower horizontal bar. During the concrete construction of the channel side wall, the two ends of the bracing rod are pressed against the inner formwork, which can effectively prevent the inner formwork from shifting or deforming due to the lateral pressure of the concrete during the concrete pouring process. This ensures the accuracy and stability of the inner formwork position, thereby guaranteeing the forming quality of the channel side wall concrete pouring.

[0027] As a further technical solution for the template trolley, the support screws are provided in multiple sets at intervals.

[0028] In this design, multiple sets of spaced-apart struts distribute the support force more evenly, providing comprehensive and balanced support to the inner formwork. This helps to further enhance the inner formwork's ability to resist lateral concrete pressure, effectively preventing localized deformation or displacement of the inner formwork at various locations, thereby greatly improving the overall stability and robustness of the inner formwork.

[0029] As a further technical solution for the template trolley, the supporting screw rod includes a threaded sleeve, a threaded screw rod, and a handle;

[0030] The threaded sleeve is horizontally connected to the lower crossbar, and both ends of the threaded sleeve are threadedly connected to the threaded screw. The handle is connected to the outer end of the threaded screw.

[0031] In this design, the threaded sleeve is threadedly connected to a threaded rod at both ends. By rotating the handle, the threaded rod rotates within the threaded sleeve, allowing for precise adjustment of the length of the support rod and thus accurate control of the support force on the inner formwork. This threaded connection method is simple to operate; the length of the support rod can be easily changed by manually rotating the handle, adapting to the support needs of different construction stages and different positions of the inner formwork, effectively improving adjustment efficiency during construction. Moreover, the threaded connection structure is relatively simple, easy to manufacture, install, and maintain, reducing equipment and maintenance costs.

[0032] As a further technical solution for the template trolley, a support plate is connected to one end of the handle away from the threaded screw, and the support plate presses against the inner template.

[0033] In this design, a support plate is connected to the handle, which presses against the inner formwork, significantly increasing the contact area between the support rod and the inner formwork. This allows the supporting force to be distributed more evenly on the inner formwork, effectively preventing damage or deformation of the inner formwork due to excessive local pressure, and further improving the stability and safety of the inner formwork during concrete pouring.

[0034] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0035] 1. The concrete construction formwork trolley of this utility model can transport formwork in both vertical and horizontal directions through the hoisting device. The operation of hoisting and delivering formwork by hand is simple and labor-saving. The position of the formwork can be flexibly adjusted, so it can adapt to the needs of channel construction of different sizes.

[0036] 2. This utility model of concrete construction formwork trolley requires a maximum of 2 people to complete the lifting, transportation and positioning of the formwork through the formwork hoisting device and the support screw rod, making the operation convenient and quick;

[0037] 3. The concrete construction formwork trolley of this utility model directly uses the configured hand chain hoist to lift and deliver the formwork, without the need for a crane to complete the operation, which reduces the space occupied by the crane and saves costs.

[0038] 4. The concrete construction formwork trolley of this utility model can easily adjust the length of the support rod by rotating the handle on the support rod. When the support rod is adjusted so that the support plates at both ends are tightly connected to the formwork, a stable overall structure can be formed. The force transmission path under this force system is single, and the two side walls support each other, effectively utilizing the load-bearing capacity of the wall itself. It is only necessary to ensure the rigidity and strength of the support rod to prevent the formwork from shifting or deforming during the pouring process, thus ensuring construction quality at low cost.

[0039] 5. The installation position of the support screw rods on the support frame of the concrete construction formwork trolley of this utility model can be added or adjusted according to the formwork support requirements. As long as the support screw rods and the support frame are reliably connected, the installation involves fewer procedures, the operation accuracy requirements are not high, and the installation is simple and quick.

The roller 3011 is set in the sliding matching cavity. The lower end of the wheel groove box 3012 is connected to a hand chain hoist 302. The other end of the hand chain hoist 302 is connected to the template through a hook. By manually driving or using other electric drive components, the roller 3011 can be moved along the crossbeam 204, thereby driving the inner template 7 and the outer template 8 to move towards the channel sidewall through the wheel groove box 3012.
