[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0021] like Figures 1-12 As shown: First embodiment: This embodiment provides a prefabricated station assembly trolley, including a base frame 1, a guardrail 2 on the upper part of the base frame 1, two main ladders 3 connected to the guardrail 2, positioning mechanisms 4 on both sides of the base frame 1, a traveling mechanism 5 at the bottom of the base frame 1, control boxes 6 on both sides of the upper part of the base frame 1, and a support frame 7 slidably mounted on the upper part of the base frame 1. The base frame 1 serves as the load-bearing and installation base for the entire vehicle, integrating the traveling, positioning, clamping, and lifting components onto the same platform; the guardrail 2 and the main ladders 3 form a passageway for personnel to move up and down and for protection; the support frame 7 is slidably arranged relative to the base frame 1, providing an adjustable installation and operating position for the subsequent splicing device 9.

[0022] The traveling mechanism 5 includes a transverse fixed frame 51, with a U-shaped fixed plate 52 fixedly connected to the bottom of the transverse fixed frame 51. Multiple traveling rollers 53 and a drive motor 54 are arranged inside the U-shaped fixed plate 52. The output shaft of the drive motor 54 is connected to the traveling rollers 53 via a transmission connection. The traveling rollers 53 are set on a pre-laid traveling track 8 in the construction area (e.g., laid on the upper surface of the bottom precast block or the construction base surface). The drive motor 54 drives the traveling rollers 53 to travel in the traveling track 8. The drive motor 54 outputs torque, which drives the traveling rollers 53 to rotate via a transmission connection. The rolling contact between the traveling rollers 53 and the traveling track 8 generates traction, causing the transverse fixed frame 51 and its supporting base frame 1 to translate along the track 8, thus realizing the movement and parking of the entire vehicle. Through track guidance and motor-driven movement, the trolley can quickly reach its designated position within the construction area along a predetermined path, reducing the inefficiency and deviation risks caused by manual pushing or repeated hoisting and traction, and improving positioning efficiency and movement controllability.

[0023] A splicing device 9 is slidably mounted on the upper part of the support frame 7. A first ladder 10 and a second ladder 11 are located on both sides of the support frame 7, and the first ladder 10 and second ladder 11 are interconnected. Clamping mechanisms 12 are located on both sides of the support frame 7. The splicing device 9 is used to splice the top precast blocks. The splicing device 9, as a support and lifting fixture for the top components, is installed on the support frame 7 and its overall position is adjusted along with the support frame 7. The first ladder 10 and second ladder 11 provide access for personnel to enter the support frame work area. The clamping mechanisms 12 are arranged on both sides of the frame to facilitate clamping and fixing the side precast blocks in the work area. Arranging the "top component splicing fixture" and the "side component clamping fixture" on the same adjustable frame allows personnel to complete multiple collaborative operations on the same work platform, improving on-site assembly efficiency and reducing the difficulty of collaboration.

[0024] The splicing device 9 includes two sliding base plates 91, with a telescopic hydraulic rod 92 positioned between them. A lifting platform 93 is mounted on top of the sliding base plates 91, and a support platform 94 is mounted on top of the lifting platform 93. Multiple hydraulic jacks 95 are mounted on the support platform 94, and a support beam 96 is mounted on top of the two hydraulic jacks 95. The telescopic hydraulic rod 92 extends and retracts to change the relative distance / position of the two sliding base plates 91, thereby adjusting the lateral position of the splicing device. The lifting platform 93 provides overall height adjustment. The hydraulic jacks 95 apply a lifting force to the support beam 96, causing the beam 96 to provide support and lifting for the top precast blocks.

[0025] The base frame 1 includes a first traveling platform 101. A first support plate 102 is fixedly connected to the bottom of the first traveling platform 101. Multiple telescopic support legs 103 are fixedly connected to both sides of the bottom of the first support plate 102. The telescopic support legs 103 are reinforced to the first support plate 102 by fasteners 104. A fixing plate 105 is fixedly connected between two telescopic support legs 103. The bottom of the telescopic support legs 103 is connected to the traveling mechanism 5. The first traveling platform 101 and the first support plate 102 constitute a bearing platform and a force transmission base. The telescopic support legs 103 transmit the upper load to the traveling mechanism 5 and can be extended and retracted to adjust the support height / support status when needed. The fasteners 104 and the fixing plate 105 reinforce and connect the support legs 103, improving the overall rigidity and resistance to lateral deformation of the support system. Through multi-point telescopic support and reinforcement connection, the structural stability of the trolley during the lifting of the top precast block is improved, reducing swaying and deformation, which helps to ensure assembly accuracy and operational safety.

[0026] The support frame 7 includes multiple support legs 71, with a second traveling platform 72 fixedly connected to each support leg 71. A first assembly rod 73 and a fixed rod 74 are fixedly connected between two support legs 71. The bottom of the second traveling platform 72 is fixedly connected to the first assembly rod 73 via a second assembly rod 75. The multiple support legs 71 and the second traveling platform 72 form a frame platform for personnel to stand / operate. The first assembly rod 73, the fixed rod 74, and the second assembly rod 75 constitute lateral and diagonal connecting stiffeners, used to distribute loads and improve the overall rigidity and stability of the frame. Through the stiffening of the rods and the platform-like frame structure, the load-bearing reliability and deformation resistance of the work platform are improved, providing a stable structural foundation for top lifting, side clamping, and other working conditions.

[0027] The control box 6 is mounted on the first traveling platform 101. The guardrail 2 is fixedly connected to one side of the upper part of the first traveling platform 101. A slide rail 13 is mounted on the first traveling platform 101, and the support frame 7 is slidably mounted on the slide rail 13. The main ladder 3 is connected to the guardrail 2. Positioning mechanisms 4 are located on both sides of the first support plate 102. The centralized arrangement of the control box 6 on the first traveling platform 101 facilitates operation and wiring. The slide rail 13 provides linear guidance and sliding support for the support frame 7, allowing the support frame 7 to achieve relative displacement along the slide rail. The positioning mechanisms 4 are located on both sides of the first support plate 102, facilitating lateral positioning of the side precast blocks. The "adjustable slide rail guidance" makes the adjustment of the working frame position more intuitive and controllable; the centralized arrangement of the control box improves operational convenience; and the reasonable arrangement of the positioning mechanisms enhances the accessibility and consistency of lateral component positioning.

[0028] The positioning mechanism 4 includes a positioning pin 41 for precisely positioning the side prefabricated block to be assembled and a positioning block 42 for supporting and / or limiting the side prefabricated block to be assembled in cooperation with the positioning pin. The positioning pin 41, as a limiting reference element, forms an insertion / abutment positioning relationship with the side prefabricated block, providing a clear positioning reference; the positioning block 42 cooperates with the positioning pin 41 to provide a supporting surface or limiting surface for the side prefabricated block, suppressing lateral displacement and tilting of the side prefabricated block under stress.

[0029] The clamping mechanism 12 includes a clamping arm 121, on which a clamping force adjuster 122 is provided. The clamping arm 121 fixes the side precast block through the clamping force adjuster 122. A buffer pad 14 is provided on the clamping mechanism 12. The clamping force adjuster 122 outputs an adjustable clamping force or clamping stroke, driving the clamping arm 121 to apply clamping pressure to the side precast block, so that the side precast block and the trolley form a controlled clamping and fixing relationship, preventing relative slippage of the side precast block during alignment and splicing. The buffer pad 14 is located at the clamping contact interface, providing elastic deformation and pressure dispersion when the clamping arm 121 applies force, reducing local contact stress and hard contact impact.

[0030] The control box 6 houses a control system, which is used to centrally control and coordinate the various actuators of the assembly trolley. The control system is electrically connected to the traveling mechanism 5, the telescopic hydraulic rod 92, the hydraulic jack 95, and the clamping mechanism 12. This "electrical connection" includes both power supply and control signal connections. The control system can drive corresponding motors, control valve groups, or actuators by outputting control signals, thereby controlling the actions of each mechanism.

[0031] Specifically, for the walking mechanism 5, the control system is electrically connected to the drive motor 54, and can control the start, stop, forward and reverse rotation and speed of the drive motor 54, thereby driving the walking roller 53 to walk on the walking track 8, realizing the movement and positioning of the assembly trolley; for the splicing device 9, the control system is electrically connected to the corresponding electronic control actuators (such as solenoid valves / valve groups or their drivers) of the telescopic hydraulic rod 92 and the hydraulic jack 95, thereby controlling the extension and retraction of the telescopic hydraulic rod 92 to adjust the relative position of the two sliding base plates 91, and controlling the lifting / lowering of the hydraulic jack 95 to lift and support the support beam 96; in some embodiments, if the lifting platform 93 is a hydraulically driven or electrically lifted structure, the control system can also realize the height adjustment of the lifting platform 93 by electrically connecting with its drive element, so as to cooperate with the hydraulic jack 95 to complete the fine adjustment of the lifting height.

[0032] For the clamping mechanism 12, the control system is electrically connected to the clamping force adjuster 122, which can adjust the clamping force or clamping stroke of the clamping arm 121 to achieve clamping, fixing and releasing of the side prefabricated blocks to be assembled. In an optional embodiment, the control system can also be electrically connected to the drive element of the telescopic support leg 103 to control the extension and retraction of the telescopic support leg 103, thereby adjusting the support height or support state of the base frame 1. Through the above control methods, the control system can coordinate and control actions such as walking, lateral positioning and clamping, top component lifting support and position adjustment, improving the operability and safety of the assembly operation.

[0033] Working principle: In this embodiment, the assembly trolley is placed on the pre-laid bottom precast blocks' travel track 8. The base frame 1 of the assembly trolley consists of a first travel platform 101, a first support plate 102, and multiple telescopic support legs 103. These telescopic support legs are reinforced to the first support plate 102 by fasteners 104 to ensure the stability of the overall structure. The bottom of the telescopic support legs 103 is connected to a travel mechanism 5, which includes a transverse fixing frame 51 and a U-shaped fixing plate 52, and has multiple travel rollers 53 and a drive motor 54 inside. By controlling the rotation of the travel rollers 53 through the drive motor 54, the assembly trolley can move flexibly on the travel track 8.

[0034] A guardrail 2 is installed on the upper part of the base frame 1 to ensure the safety of construction personnel, and a main ladder 3 facilitates the movement of construction personnel up and down. Positioning mechanisms 4 are set on both sides of the base frame 1, including positioning pins 41 and positioning blocks 42, for accurately positioning the position of the side precast blocks. At the same time, a support frame 7 is slidably installed on the upper part of the base frame 1. This frame is connected to the first traveling platform 101 through a slide rail 13 and its position can be adjusted as needed.

[0035] When it is necessary to install the side precast blocks, construction workers enter the support frame 7 via the first ladder 10 and the second ladder 11. A splicing device 9 is slidably installed on the upper part of the support frame 7, which can be precisely adjusted in height to match the installation position of the top precast blocks for splicing. In addition, clamping mechanisms 12 are provided on both sides of the support frame 7. The clamping arms 121 fix the precast blocks through clamping force adjusters 122, and buffer pads 14 are also provided on the clamping arms to avoid damage to the precast blocks.

[0036] The splicing device 9 includes a sliding base plate 91, a telescopic hydraulic rod 92, a lifting platform 93, a support platform 94, hydraulic jacks 95, and a support beam 96. When it is necessary to install the top precast blocks, the position of the sliding base plate 91 is first adjusted by the telescopic hydraulic rod 92, and then lifted to an appropriate height by the lifting platform 93. The hydraulic jacks 95 on the lifting platform 93 and the hydraulic jacks 95 on the support platform 94 complete the fixing and splicing of the top precast blocks through the support beam 96.

[0037] The support frame 7 consists of multiple support legs 71, which are bolted to the second traveling platform 72, providing a stable operating platform for construction workers. Simultaneously, a first assembly rod 73 and a fixing rod 74 are installed between two support legs 71 to enhance the rigidity and stability of the overall structure, ensuring no deformation occurs when bearing heavy loads. Furthermore, the bottom of the second traveling platform 72 is further fixedly connected to the first assembly rod 73 via a second assembly rod 75. This modular design not only improves assembly efficiency but also facilitates disassembly and maintenance.

[0038] The entire assembly process is managed by the control system in control box 6. This system is connected to clamping force adjuster 122, drive motor 54, telescopic support leg 103, and splicing device 9 to achieve automated control. Construction personnel can set the target position through the control box, and drive motor 54 drives traveling roller 53 to move to the designated area; subsequently, hydraulic jack 95 adjusts the height of the support frame, and clamping mechanism 12 fixes the precast blocks to complete precise assembly.

[0039] Second embodiment: Based on Embodiment 1, this embodiment further improves the splicing device 9: Two sets of telescopic hydraulic rods 92 are symmetrically arranged, with their output ends hinged together. The other end of each set of telescopic hydraulic rods 92 is fixedly connected to a sliding base plate 91. A lifting frame 97 is hinged to the lower part of the hinge joint of the two sets of telescopic hydraulic rods 92. A tilt control hydraulic cylinder 98 is connected to the lower end of the lifting frame 97. The sliding base plate 91 is slidably mounted on the support frame 7 via a slide groove 76. Sliding shafts 99 extending into the slide groove 76 are fixedly installed on both sides of the outer end of the sliding base plate 91. The slide groove 76 is a T-shaped slide groove.

[0040] Other structures are consistent with those in Embodiment 1. In this embodiment, the splicing device 9 can not only slide horizontally to facilitate the assembly of flat-top prefabricated components, but also tilt on both sides when the tilt control hydraulic cylinder 98 controls the lifting frame 97 to rise and fall, thereby facilitating the assembly of sloping-top prefabricated components or arched prefabricated components, making it convenient to switch between them.

[0041] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the principles of the present invention should be included within the scope of protection of the present invention.
