[0001] This utility model relates to the field of construction trolley technology, and in particular to a trolley component and construction trolley that can be quickly disassembled. Background Technology

[0002] A utility tunnel, also known as a pipeline corridor, is a building structure specifically designed for the centralized placement of various pipelines. Like an underground transportation hub, it cleverly integrates the city's lifelines—gas, heating, water supply and drainage, and various communication engineering pipelines. This centralized layout not only facilitates the rational use of urban space but also enables unified planning, design, construction, and management of pipelines, significantly improving the construction and operational efficiency of urban infrastructure. Therefore, utility tunnels have become an important form of modern urban underground space development and are of great significance for promoting sustainable urban development.

[0003] Deep underground, these intricate pipeline systems are cleverly housed in utility tunnels, ensuring smooth urban operations while minimizing the use of surface space and reducing visual clutter. The construction of these utility tunnels not only reflects the wisdom of urban management but also embodies the advancements in modern engineering technology.

[0050] Example 1

[0051] Referring to Figures 1-5, this embodiment presents a trolley assembly for quick demolding. The trolley assembly 2 includes a frame 21, a top mold adjusting component 22, two sets of side mold adjusting components 24, a template assembly 25, and a control mechanism (not shown in the figures). The template assembly 25 includes a top mold 251 and two side molds 252. The top mold 251 is located at the top of the frame 21, and the side molds 252 are respectively located on both sides of the frame 21. The upper ends of the side molds 252 are rotatably connected to the top mold 251. The side mold adjusting components 24 are connected to the frame 21 and the side molds 252 respectively, and can drive the corresponding side molds 252 to rotate toward or away from the frame 21. Here, there is no specific limitation on the number of each set of side mold adjusting components 24. The number of each set of side mold adjusting components 24 can be one as shown in Figure 1. To improve the control stability of each set of side mold adjusting components 24 on the side molds 252, the number of each set of side mold adjusting components 24 can also be multiple. One end of the top formwork adjusting component 22 is connected to the lower end of the platform 21, and the other end of the top formwork adjusting component 22 can be supported on the construction ground. The top formwork adjusting component 22 can extend and retract vertically, driving the platform 21 to rise and fall vertically, thereby raising or lowering the top formwork 251. Both the top formwork adjusting component 22 and the side formwork adjusting component 24 are connected to the control mechanism. The control mechanism adopts advanced electronic control technology, such as PLC (Programmable Logic Controller) or microcontroller, to achieve intelligent control.

[0052] Referring to Figures 1-3, when the construction trolley moves to the construction area and concrete pouring is required, the side formwork adjusting member 24 drives the corresponding side formwork 252 to rotate away from the platform 21 to a preset position, and the top formwork adjusting member 22 extends vertically, driving the platform 21 to extend vertically as well, raising the top formwork 251 to a preset height, forming the state shown in Figure 1. Then, concrete pouring is carried out. The top formwork 251 and side formwork 252 are used to adhere to the concrete surface after pouring to support the entire concrete until the concrete initially sets and reaches the demolding strength. Here, the preset position and preset height are designed based on the curve radius and height of the pipe gallery. When the concrete reaches the demolding strength and demolding is required, the side formwork adjusting member 24 drives the side formwork 252 to rotate towards the platform 21, and the top formwork adjusting member 22 shortens vertically to lower the top formwork 251, forming the state shown in Figure 2, for demolding.

[0053] By setting up top formwork adjustment components 22 and side formwork adjustment components 24, the system can adapt to pipe gallery construction with different curve radii and heights, improving construction flexibility and versatility. Furthermore, after concrete pouring, remote and rapid formwork removal can be achieved using a control mechanism, eliminating the need for construction personnel to enter the construction site for removal. This ensures the safety of construction workers and effectively shortens removal time, improving construction efficiency. The precise adjustment components 24 and 22 ensure the flatness and verticality of the side formwork 252 and top formwork 251, improving the construction quality of the pipe gallery.

[0054] In this embodiment, the top formwork adjustment component 22 and the side formwork adjustment component 24 cooperate with the control mechanism. In one specific embodiment, referring to Figure 1, the construction trolley also includes a first support component 4. The first end of the first support component 4 is rotatably connected to the frame 21, and the second end of the first support component 4 is detachably connected to the top formwork 251. The first support component 4 is telescopic to adjust its length. When the side formwork 252 is in contact with the surface of the poured concrete, by adjusting the length of the first support component 4 until the state shown in Figure 1 is formed, the first support component 4 can apply a force towards the pipe gallery to the side formwork 252 for support. This force helps to ensure that the side formwork 252 is tightly in contact with the surface of the concrete, reducing leakage and deformation of the concrete during the pouring process, thus facilitating concrete shaping.

[0055] In one specific embodiment, referring to Figures 1 and 3, the construction trolley further includes a formwork support 5, a sliding block 6, and a second support member 7. The formwork support 5 is located between the top mold 251 and the platform 21, and is connected to the top mold 251. The formwork support 5 provides additional support for the top mold 251, ensuring the stability of the top mold 251 during concrete pouring. The bottom of the formwork support 5 is provided with a sliding groove (not shown in the figure), and the sliding block 6 is slidably disposed in the sliding groove and abuts against the sliding groove, ensuring that the sliding block 6 moves smoothly within the sliding groove. The second support member 7 is arranged horizontally and is telescopic. The second support member 7 is connected to the platform 21 and the sliding groove respectively. During the telescopic process of the second support member 7, it can push the sliding block 6 to move along the sliding groove.

[0056] During the concrete pouring process, uneven concrete pouring may occur, resulting in sunken areas. The second support member 7 pushes the sliding block 6 to move to the sunken area and pushes the formwork 5 upward to eliminate the sunken area and unevenness. This allows for fine-tuning of the top formwork 251 in the vertical direction, improving construction accuracy and quality.

[0057] In one specific embodiment, referring to Figure 1, the trolley assembly further includes a traveling component 23. A guide rail 1 can be laid on the construction ground to provide a track for the trolley assembly 2 to move. The lower end of the platform 21 is connected to the traveling component 23, which can drive the platform 21 to move along the guide rail 1, facilitating the movement of the entire trolley assembly 2 to the construction position for concrete pouring.

[0058] In one specific embodiment, referring to Figures 1 and 2, the traveling assembly 23 includes traveling wheels 231 and a drive device (not shown in the figures). The traveling wheels 231 are rolledly connected to the lower end of the platform 21, and the rolling connection can be achieved through bearings or similar devices to reduce friction and wear. The traveling wheels 231 are mounted on the guide rail 1 to ensure that the trolley can move smoothly and steadily along the guide rail 1. The drive device is connected to the traveling wheels 231 and is used to drive the traveling wheels 231 to move along the guide rail 1. The drive device may include components such as a motor, reducer, and transmission device to transmit power to the traveling wheels 231 and drive them to move along the guide rail 1. The drive device can be connected to a control system and operated through remote control, manual control, etc. The control system can precisely control the output power and speed of the drive device according to construction needs, thereby achieving precise control of the movement speed and position of the entire construction trolley.

[0059] In one specific embodiment, referring to Figures 1 and 2, the drive device includes a motor fixed to the frame 21. The motor type can be a DC motor, AC motor, or stepper motor, etc., depending on the performance requirements of the construction trolley and the working environment. The motor is the power source of the drive device, generating rotational motion according to control signals or operating commands. The motor's output shaft is connected to the traveling wheels 231 through a connecting mechanism, converting the rotational motion into the rolling motion of the traveling wheels 231, thereby driving the construction trolley to move along the guide rail 1. By precisely controlling the rotational speed and direction of the motor, precise control of the construction trolley's movement speed and position can be achieved, improving construction accuracy.

[0060] In one specific embodiment, referring to Figures 1 and 2, the side mold adjusting member 24 includes a hydraulic assembly. A hydraulic assembly is a transmission system that uses a liquid (typically mineral oil or synthetic oil) as a working medium, transmitting energy and performing control actions through the pressure energy of the liquid. The hydraulic assembly includes power components (such as a hydraulic pump), actuators (such as hydraulic cylinders or hydraulic motors), control components (such as directional control valves, pressure control valves, and flow control valves), and auxiliary components (such as oil tanks, oil filters, coolers, and accumulators). The rotation of the side mold 252 can be driven by the extension and retraction of the actuators, achieving support or demolding of the concrete surface.

[0061] Example 2

[0062] The inventors discovered that when planning and designing utility tunnels, it is necessary to pass through and avoid existing urban pipelines and structures, requiring the design of multiple small-radius curves, steep slopes, and sharp bends. For integrated hydraulic construction trolleys, when constructing curved utility tunnels, the trolley must be disassembled and transported in sections to the next straight section. This process is time-consuming, inefficient in relocation, and compromises construction efficiency.

[0063] Based on the same inventive concept, this embodiment proposes a construction trolley, including at least one trolley component as described in Embodiment 1.

[0064] In one specific embodiment, referring to Figure 1, the construction trolley includes multiple trolley components and a hinge connection mechanism; the side molds 252 of adjacent trolley components 2 are connected by the hinge connection mechanism 3, and multiple trolley components 2 can form a whole to carry out the construction of the curved pipe gallery together.

[0065] Referring to Figures 1, 4, and 5, when the construction trolley travels through a straight section of the pipe gallery, it can directly pass using the traveling assembly 23. When the construction trolley encounters a curved section of the pipe gallery, a guide rail 1 with the same angle as the curved section can be laid. The hinge connection mechanism 3 between the centripetal side molds 252 of any adjacent trolley assemblies 2 is engaged, while the hinge connection mechanism 3 between the centrifugal side molds 252 is disengaged. The traveling assembly 23 is activated. At this time, any adjacent trolley assemblies 2 are connected only by the hinge connection mechanism 3 between the centripetal side molds 252. The trolley assembly 2 slowly travels along the guide rail 1, completing the passage through the curved section. Subsequent trolley assemblies 2 pass through the curved section of the pipe gallery in sequence according to the above operation.

[0066] The difference between the construction trolley in this embodiment and the conventional integrated hydraulic construction trolley is that the side molds 252 of adjacent trolley components 2 can be connected by a hinge connection mechanism 3, and are not composed of a single piece of steel template. The construction trolley in this embodiment not only possesses all the features of an integrated hydraulic construction trolley, but also, when facing curved pipe corridors, can be adjusted using the hinge connection mechanism 3 to pass through the curved pipe corridors in sections without the need for disassembly and assembly of the construction trolley, thus offering high flexibility and ensuring construction quality and efficiency.

[0067] By setting multiple trolley components 2, the entire construction trolley is modularly designed, which makes installation and disassembly convenient, can be put into construction quickly, shortens the construction cycle, and improves construction efficiency. At the same time, the number of trolley components 2 can be increased or decreased according to construction needs, which is highly flexible.

[0068] In one specific embodiment, referring to Figure 5, the hinge connection mechanism 3 includes a pin 31, a pin hole 32, and two connecting plates 33. The two connecting plates 33 are respectively connected to the side molds 252 of adjacent trolley assemblies 2. The connecting plates 33 can be made of steel or alloy, possessing sufficient strength and rigidity to withstand various loads during construction. The pin hole 32 connects the two connecting plates 33, and the shape of the pin hole 32 matches the shape of the pin 31. The position of the pin hole 32 should be determined based on the rotation range of the side molds 252 of the trolley assembly 2 and the structural dimensions of the connecting plates 33 to ensure that there is no interference with other components during rotation. The pin 31 can be inserted into the pin hole 32 to connect the side molds 252 of adjacent trolley assemblies 2.

[0069] Referring to Figures 4 and 5, the explanation will focus on the first and second small-section trolleys (i.e., trolley assembly 2 mentioned above). When the construction trolley encounters a curved pipe gallery, the connection between the centrifugal side molds 252 of the first and second small-section trolleys is loosened, i.e., the pins 31 are pulled out of the corresponding pin holes 32, while maintaining the connection between the centripetal side molds 252 of the first and second small-section trolleys, i.e., the pins 31 are inserted into the corresponding pin holes 32. The traveling assembly 23 is then activated. At this time, the first and second small-section trolleys are connected only by the centripetal side molds 252. The angle between the first and second small-section trolleys is adjusted, and they proceed slowly along guide rail 1 to complete the passage through the curved section. Through the cooperation of pin 31, pin hole 32 and connecting plate 33, reliable connection and relative rotation between side molds 252 of adjacent trolley components 2 are achieved, so that the entire construction trolley can adapt to the horizontal curve changes of the curved pipe gallery without disassembling the construction trolley, thus ensuring construction quality and efficiency.

[0070] The construction trolley used in this embodiment can be used for construction within the pipe gallery, specifically including the following steps:

[0071] Step S1: Keep the hinge connection mechanism 3 between the centripetal side molds 252 of any adjacent trolley assembly 2 in the connected state, and keep the hinge connection mechanism 3 between the centrifugal side molds 252 in the disconnected state.

[0072] Step S2: Use the walking component 23 to drive the corresponding platform 21 to move until it reaches the construction area, and connect the hinge connection mechanism 3 between the side molds 252 on the centrifugal side of any adjacent trolley components 2.

[0073] Step S3: Drive the side formwork adjustment component 24 to rotate the corresponding side formwork 252 away from the platform 21 until the side formwork 252 rotates to the preset position, support the top formwork adjustment component 22 on the construction ground, and drive the top formwork adjustment component 22 to extend vertically until the height of the top formwork 251 reaches the preset height, so as to carry out concrete pouring.

[0074] In step S3 above, when pouring concrete, concrete is poured between the side wall of the pipe gallery and the side formwork 252 and between the top plate of the pipe gallery and the top formwork 251, and the side formwork 252 and the top formwork 251 are used to support the concrete.

[0075] After the concrete is poured, the following steps are also included:

[0076] Step S4: After the concrete has initially set and formed a concrete layer, drive the side formwork adjustment component 24 to rotate the corresponding side formwork 252 toward the platform 21 until the side formwork 252 is removed from the concrete layer. Drive the top formwork adjustment component 22 to shorten in the vertical direction until the top formwork 251 is removed from the concrete layer for demolding.

[0077] Step S5: Keep the hinge connection mechanism 3 between the centripetal side molds 252 of any adjacent trolley assembly 2 in the connected state, and keep the hinge connection mechanism 3 between the centrifugal side molds 252 in the disconnected state. Use the walking assembly 23 to drive the corresponding platform 21 to move to the next construction area, and repeat the concrete pouring process of step S3 and the demolding process of step S4.

[0078] Of course, the chain-link construction trolley of Embodiment 1 can also be applied to the construction of straight pipe corridors. The only difference from the construction of curved pipe corridors is that, in step S1, for the construction of straight pipe corridors, it is not necessary to keep the hinge connection mechanism 3 between the side molds 252 on the centrifugal side in a disconnected state. It is sufficient to keep the hinge connection mechanism 3 between the side molds 252 of any adjacent trolley assembly 2 in a connected state. The remaining steps can refer to the above steps S2-S5.

[0079] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. This disclosure is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this disclosure is limited only by the appended claims. Thus, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, this utility model is also intended to include these modifications and variations.
