Abstract
Description
Technical Field
[0001] This utility model relates to the field of subway station construction technology, and in particular to a multi-functional assembly trolley. Background Technology
[0002] With the continuous development and advancement of subway construction technology, prefabricated composite stations are becoming increasingly popular among construction companies compared to cast-in-place stations. Prefabricated composite stations utilize a "dry-wet combination" scheme for connection nodes, combining this with the overall prefabricated composite station connection nodes. Based on construction requirements and node stress, innovative methods such as steel overflow connections and ring-lock lap joints are employed, significantly improving construction efficiency and shortening the construction period by 30% compared to traditional cast-in-place processes. For prefabricated buildings, the size and weight of precast components affect the construction and cost of prefabricated stations. Through structural system innovation and material optimization, the weight of precast components is reduced, and prestressed technology is used to reduce the amount of steel reinforcement and structural steel used in precast components, resulting in a reduction of approximately 10% in the overall cost of a single prefabricated station. Prefabricated station design adheres to the concept of "adapting to local conditions and maximizing prefabrication," with "high efficiency, economy, and low carbon" as its core principles, and is increasingly prevalent in the market.
[0003] However, the assembly trolleys currently available on the market are only auxiliary equipment. During construction, the trolleys need to be used in conjunction with gantry cranes to align prefabricated components. The station site is small, and only one gantry crane is configured for each station, resulting in low construction efficiency.
[0004] The patent application number "202223045574X" discloses "an assembly trolley for auxiliary installation of prefabricated buildings". Although the trolley has related structures such as prefabricated side wall installation device, prefabricated steel pipe column installation device, prefabricated middle plate installation device and prefabricated longitudinal beam installation device, the patent document does not disclose the specific structure and usage process of the aforementioned devices, which is not conducive to the use of technicians. Summary of the Invention
[0005] The purpose of this utility model is to overcome the shortcomings of the prior art. After the prefabricated components to be installed are hoisted to the designated position using a crane, the subsequent installation work of the prefabricated components can be completed independently using this trolley.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A multi-functional assembly trolley includes a traveling mechanism that can reciprocate longitudinally, wherein a side wall mounting mechanism, a central longitudinal beam mounting mechanism, and a central plate mounting mechanism are respectively provided on the traveling mechanism;
[0008] The sidewall mounting mechanism includes a first lateral movement device, a flipping device, an inner and outer support frame, a first lifting cylinder on the side wall of the inner and outer support frame, and a lifting point mounting frame that can be connected to the sidewall lifting point on the top of the inner and outer support frame.
[0009] Preferably, the first lateral movement device is connected to the tilting device via a tilting cylinder, and the side wall mounting mechanism further includes a first lateral movement cylinder that drives the first lateral movement device to move laterally.
[0010] Preferably, the side wall of the flipping device is provided with a clamping device for fixing the side wall.
[0011] Preferably, the traveling mechanism is further provided with a support frame, and the middle longitudinal beam mounting mechanism and the middle plate mounting mechanism are both provided on the support frame.
[0012] Preferably, the support frame includes a column assembly, on which a cross brace assembly is provided, and on which a central longitudinal beam installation mechanism, a central plate installation mechanism, and a platform component for construction personnel to walk are provided.
[0013] Preferably, the first lifting cylinder is provided with an extension section for adjusting its length, the lifting point mounting bracket is provided with an extension section for adjusting its length, and the column device is provided with an extension section for adjusting its length.
[0014] Preferably, the middle longitudinal beam installation mechanism includes a second transverse movement device, on which a second lifting device and a second lifting cylinder for driving the second lifting device to rise and fall are provided; the top of the lifting device is provided with a cantilever bracket for placing the middle longitudinal beam.
[0015] The longitudinal beam mounting mechanism also includes a second transverse movement cylinder that drives the second transverse movement device to move laterally.
[0016] Preferably, the middle plate mounting mechanism includes a bracket, a third lateral movement device is provided on the bracket, a third lifting device for placing the middle plate and a third lifting cylinder for driving the third lifting device to rise and fall.
[0017] The middle plate mounting mechanism also includes a third lateral movement cylinder that drives the third lateral movement device to move laterally.
[0018] Preferably, the side wall mounting mechanism is equipped with a first anti-overturning hook device; the central longitudinal beam mounting mechanism is equipped with a second anti-overturning hook device.
[0019] Preferably, the assembly trolley also includes an electrical system and a hydraulic system.
[0020] The beneficial effects of this utility model are as follows:
[0021] 1. When using this device, the gantry crane only needs to place the prefabricated component to be installed onto the trolley, and then the hook can be detached to carry out other operations, which greatly improves the installation efficiency.
[0022] 2. The first lifting cylinder, the hoisting point mounting frame, and the column device are all equipped with extension sections for adjusting their length, which makes the device suitable for construction environments with different drops and increases the application range of the equipment.
[0023] 3. Secure the side wall with clamps to prevent it from shaking or falling off during transport and to avoid accidents.
[0024] 4. Due to the small area occupied by the subway construction site, if the station is set up with a multi-layer structure, the on-site grooving and cross bracing are complicated, and it is difficult for the gantry crane to lift the prefabricated components into the lower layer. On-site, only one hole can be reserved for lifting the prefabricated components into the lower layer. The prefabricated components can be placed on the multi-functional assembly trolley, and the multi-functional assembly trolley can complete the remaining work. Attached Figure Description

[0040] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. Detailed Implementation
[0041] The present invention will now be further described with reference to the accompanying drawings.
[0042] Example 1
[0043] like Figure 1 and Figure 2 As shown, a multi-functional assembly trolley in this embodiment includes a traveling mechanism 1 that can reciprocate longitudinally. The traveling mechanism 1 is respectively equipped with a side wall mounting mechanism 3, a central longitudinal beam mounting mechanism 4, and a central plate mounting mechanism 5.
[0044] like Figure 12 and Figure 13 As shown, the traveling mechanism 1 includes two sets of traveling wheel boxes 8 and two sets of drive reduction motors 9. It adopts a three-in-one reducer motor drive and frequency converter control, so that the trolley and the prefabricated parts placed on it can move back and forth longitudinally.
[0045] like Figure 3 — Figure 5As shown, the side wall mounting mechanism 3 includes a first transverse movement device 13, on which a flipping device 14 is provided. Since the side wall 100 is generally placed flat or at a certain angle to the horizontal plane during transportation, and is generally installed vertically during installation, the flipping device 14 allows for adjustment of the side wall 100's posture during transportation and installation. The flipping device 14 is equipped with an inner and outer support frame 15, with a first lifting cylinder 18 on the side wall of the inner and outer support frame 15. The top of the inner and outer support frame 15 is equipped with a lifting point mounting frame 21 that can connect to the lifting points of the side wall 100. The first lifting cylinder 18 can drive the inner and outer support frame 15 to move up and down, achieving installation of the side wall 100 at a designated position. Lifting points are pre-set on the side wall 100, which can be connected to the mounting pins of the lifting point mounting frame 21. After the gantry crane places the side wall 100 on the side wall mounting mechanism 3, the lifting point mounting frame 21 connects to the side wall 100, preventing it from falling during transportation.
[0046] In this embodiment, the first lateral movement device 13 is connected to the flipping device 14 via the flipping cylinder 16. When transporting the side wall 100, the flipping cylinder 16 retracts, causing the flipping device 14 to rotate to the right, facilitating the placement of the side wall 100 on the side wall mounting mechanism 3. After moving to the installation position, the flipping cylinder 16 extends, causing the flipping device 14 to be in a vertical state, facilitating the installation of the side wall 100. The side wall mounting mechanism 3 also includes a first lateral movement cylinder 17 that drives the first lateral movement device 13 to move laterally. The first lateral movement cylinder 17 can drive the side wall mounting mechanism 3 to move laterally as a whole, while the traveling mechanism 1 can drive the side wall mounting mechanism 3 to move longitudinally. Furthermore, the position of the side wall 100 can be adjusted by the up-and-down movement of the first lifting cylinder 18, allowing it to be installed in any designated position.
[0047] To further secure the sidewall 100 during transport, the sidewall of the flipping device 14 is provided with a clamping device 19 for securing the sidewall 100. For example... Figure 3 As shown, in order to better fix the side wall 100, there are two clamping devices 19 in this embodiment. The upper clamping device 19 is installed on the inner and outer support frame 15, and the lower clamping device 19 is installed on the flipping device 14.
[0048] The clamp device 19 is a conventional product, and its connection method with the side wall 100 is also a conventional connection method, which will not be described in detail in this embodiment.
[0049] like Figure 1 and Figure 11 As shown, a support frame 2 is also provided on the traveling mechanism 1, and the middle longitudinal beam mounting mechanism 4 and the middle plate mounting mechanism 5 are both provided on the support frame 2.
[0050] The supporting frame 2 includes a column assembly 11, on which a cross brace assembly 10 is installed. The cross brace assembly 10 is equipped with a central longitudinal beam installation mechanism 4, a central plate installation mechanism 5, and a platform assembly 12 for construction personnel to walk on. The entire top surface of the frame is covered with steel mesh to serve as a platform for personnel passage and operation.
[0051] To adapt to construction environments at different heights, extension sections for adjusting the length are provided on the first lifting cylinder 18, the lifting point mounting frame 21, and the column device 11. During construction, adjustments can be made according to the specific height, improving the equipment's versatility.
[0052] like Figure 6 and Figure 7 As shown, the middle longitudinal beam installation mechanism 4 includes a second transverse movement device 22, a second lifting device 23 and a second lifting cylinder 26 that drives the second lifting device 23 to rise and fall, and a cantilever bracket 24 for placing the middle longitudinal beam 200 is provided on the top of the lifting device 23.
[0053] The longitudinal beam mounting mechanism 4 also includes a second transverse movement cylinder 25 that drives the second transverse movement device 22 to move laterally. The second transverse movement cylinder 25 can push the second transverse movement device 22 and the longitudinal beam mounting mechanism 4 to move laterally as a whole, moving the longitudinal beam 200 to the designated position for installation.
[0054] To ensure the safety of this device during use, a first anti-tipping hook device 20 is installed on the side wall mounting mechanism 3; a second anti-tipping hook device 27 is installed on the central longitudinal beam mounting mechanism 4. The side wall mounting mechanism 3 and the central longitudinal beam mounting mechanism 4 are anchored respectively. The first anti-tipping hook device 20 and the second anti-tipping hook device 27 move with the first transverse hydraulic cylinder 17 and the second transverse hydraulic cylinder 25 respectively, ensuring equipment safety. The specific structure of the anti-tipping device is existing conventional technology and will not be detailed in this embodiment.
[0055] like Figure 8 — Figure 10 As shown, the middle plate mounting mechanism 5 includes a bracket 30, a third transverse movement device 28 is provided on the bracket 30, a third lifting device 29 for placing the middle plate 300 and a third lifting cylinder 32 for driving the third lifting device 29 to rise and fall; the middle plate mounting mechanism 5 also includes a third transverse movement cylinder 31 for driving the third transverse movement device 28 to move laterally.
[0056] In this embodiment, the subway station to be constructed is divided into a second basement level and a first basement level. The height difference between the second basement level and the first basement level is greater than that between the first basement level. In the actual construction process, the trolley is first moved to the second basement level for construction, and then moved to the first basement level for construction. Figure 4 and Figure 14As shown, during the construction of the second basement level, the longitudinal beam 200 is first installed in place using the longitudinal beam installation mechanism 4, then the side wall 100 is installed in place using the side wall installation mechanism 3, and finally the middle plate 300 is installed in place using the middle plate installation mechanism 5.
[0057] When installing the longitudinal beam 200, first use a gantry crane to place the prefabricated longitudinal beam 200 on the longitudinal beam installation mechanism 4 (i.e., cantilever bracket 24). Start the traveling mechanism 1 to reach the longitudinal installation position of the longitudinal beam 200. Start the second lifting cylinder 26 to raise the longitudinal beam 200 to the predetermined installation height. Start the second transverse cylinder 25 to move the longitudinal beam 200 laterally to the predetermined transverse position. After precise alignment, install the anchoring device. Then, the second lifting cylinder 26 lowers, the second transverse cylinder 25 retracts, and the equipment detaches.
[0058] When installing the side wall 100, first use a gantry crane to place the prefabricated side wall 100 onto the side wall installation mechanism 3, and then fix it using the lifting point mounting bracket 21 and the clamp device 19. Figure 14 The side wall mounting mechanism 3 shown is a schematic diagram of the placement of the side wall 100. Then, the traveling mechanism 1 is activated to reach the longitudinal installation position of the side wall 100. Next, the tilting cylinder 16 is activated to tilt the side wall 100 to a vertical position. Then, the first transverse cylinder 17 is activated to move the side wall 100 to a transverse installation position. Finally, the first lifting cylinder 18 is activated to lower the side wall to the predetermined height. After precise alignment, the anchoring device is installed. Afterwards, the lifting point mounting bracket 21 is removed, the first transverse cylinder 17 retracts, the first lifting cylinder 18 rises, the tilting cylinder 16 retracts, and the equipment is detached.
[0059] When installing the middle plate 300, first use a gantry crane to place the prefabricated middle plate 300 on the middle plate installation mechanism 5 (i.e., the third lifting device 29). Start the traveling mechanism 1 to reach the longitudinal installation position of the middle plate 300. Start the third transverse movement cylinder 31 to move the middle plate 300 laterally to the transverse installation position. Start the third lifting cylinder 32 to lift the middle plate 300 to the predetermined position. After precise alignment, install the anchoring device. Then, the third lifting cylinder 32 descends, the third transverse movement cylinder 31 retracts, and the equipment detaches.
[0060] like Figure 5 and Figure 15 As shown, during construction on the basement level, the trolley is first moved to the basement level. Then, the longitudinal beam 200 is installed in place using the longitudinal beam installation mechanism 4. Next, the side wall 100 is installed in place using the side wall installation mechanism 3. Finally, the middle plate 300 is installed in place using the middle plate installation mechanism 5. The height of the support frame 2 is adjusted by adjusting the length of the column extension section to accommodate changes in height difference.
[0061] In this embodiment, the installation process of the central longitudinal beam 200 and the central plate 300 is the same as the installation process of the aforementioned second basement level, only the installation process of the side wall 100 needs to be adjusted.
[0062] like Figure 15 As shown in the figure, the two side wall mounting mechanisms 3 are the positions of the side wall 100 during transportation and the side wall 100 after installation. When the side wall 100 is installed, the middle plate 300 has not yet been installed, so the middle plate 300 and the side wall mounting mechanism 3 will not interfere or collide.
[0063] When installing the side wall 100, first remove the upper extension section of the first lifting cylinder 18 and replace the upper bracket. Then remove the extension section of the lifting point mounting bracket 21 to match the floor height of the basement. First, use a gantry crane to place the prefabricated side wall 100 on the side wall installation mechanism 3 and fix it with the lifting point mounting bracket 21 and the clamp device 19. Then, start the traveling mechanism 1 to reach the longitudinal installation position of the side wall 100. Then, start the tilting cylinder 16 to tilt the side wall 100 to make it vertical. Then, start the first transverse cylinder 17 to move the side wall 100 to the transverse installation position. Finally, start the first lifting cylinder 18 to lower the side wall to the predetermined height. After precise alignment, install the anchoring device. The side wall 100 installation is complete.
[0064] This assembly trolley also includes an electrical system 6 and a hydraulic system 7. The electrical system 6 includes the overall control system and the prefabricated component precision alignment system; the hydraulic system 7 includes cylinders, hydraulic pipelines, and pump stations. The hydraulic system adopts an independent unit modular design, which can effectively reduce system pipeline friction loss, reduce power loss, and facilitate maintenance.
[0065] This device employs 22 sensors. The component positioning and guidance system uses the already installed first ring as a reference, therefore the installation of the first ring requires manual inspection and control of accuracy. After the first ring is installed correctly, the sensors detect the verticality of the current component, the distance to the component in the previous ring, and the distance to the front of the current component. Through mutual calibration of the four sensors, the operator is guided to install the component in place.
[0066] The multi-functional assembly trolley disclosed in this embodiment can complete the assembly and installation of prefabricated components for composite stations without the assistance of a gantry crane, thus improving construction efficiency; it can also perform prefabricated component assembly operations with small openings, saving land acquisition area; and it is equipped with a prefabricated component precision alignment system, ensuring the reliability of construction.
