Description

Technical Field

[0001] This invention relates to the technical field of construction engineering, and in particular to a wall-hanging tool trolley. Background Technology

[0002] Platform screen door slabs are prefabricated wall structures used to install or support platform screen doors and equipment. Platform screen door slabs are a new type of prefabricated component, with a T-shaped shape and a standard longitudinal module of 1.5m.

[0003] In actual construction, platform gantry cranes are characterized by large component weight, high installation height, and high positioning accuracy requirements. At the same time, as enclosed underground spaces, subway platforms generally have a long and narrow passage structure, with limited available construction space. In particular, conventional large lifting equipment (such as truck cranes and gantry cranes) cannot be used near station equipment areas and track areas.

[0004] Currently, there are no universally applicable equipment or facilities for installation, so manual handling combined with simple tools can be used. The typical operation method includes: manually using crowbars, rollers, or handcarts to transport the prefabricated hanging wall components to the work surface, then using manual hoists, chain hoists, and tripods to lift the components to the design elevation, and manually controlling the alignment and fixing.

[0005] These devices are mostly decentralized and independently used tools, relying on manual labor for transportation, lifting, alignment, and fixing. They lack systematic collaborative design, resulting in a fragmented overall workflow and low efficiency. The narrow and long interior space of subway platforms, densely packed with equipment, makes it difficult to deploy equipment such as triangular supports and chain hoists, and limits lifting space. Once site conditions are restricted, the equipment is difficult to deploy or the direction of force is limited, which can easily lead to the tilting of lifting components and failure to align with the reserved sleeves for installation. Manual devices experience large swaying during lifting, resulting in poor operational stability and difficulty in achieving precise vertical and horizontal positioning of the suspended wall, causing misalignment of screws and sleeves, affecting installation quality. All lifting and alignment operations rely on manual judgment and coordination, lacking functions such as displacement limit, torque control, and automatic protection. Human error can easily cause the suspended object to sway, deviate, or even fall, posing a high safety hazard. Most of the existing equipment is assembled on-site or temporarily processed, lacking modular and standardized design. After construction, most of it cannot be reused, which is not conducive to resource utilization and cost control.

[0006] Furthermore, existing construction methods mainly rely on manual labor combined with simple lifting devices, which have problems such as high labor intensity, low efficiency, high safety risks, and difficulty in aligning components, making it difficult to meet the actual needs of subway construction for efficient, safe, and precise installation. Summary of the Invention

[0007] The purpose of this invention is to provide a wall-mounting tool trolley to alleviate the technical problems of difficult wall-mounting installation of platform doors and low construction efficiency in subway platforms due to the limited working space.

[0008] This invention provides a wall-mounted tooling trolley, comprising an operating platform, at least one standard section, and a lifting section arranged sequentially from top to bottom; The operating platform includes a platform body, on which a first support arm and a second support arm are provided, and a clamping groove is formed between the first support arm and the second support arm; the lower end of the hanging wall is inserted into the clamping groove, and the upper ends of the first support arm and the second support arm are used to abut against the hanging wall.

In an optional embodiment, the platform body is further provided with a third support arm, which is located on the side of the second support arm away from the first support arm. A support plate is provided at the upper end of the third support arm. The support plate is connected to the second support arm, and the support plate and the second support arm form a support surface for supporting the suspended wall.

[0010] In an optional implementation, the platform body is provided with a protective railing.

[0011] In an optional implementation, a ladder is provided on the platform body.

[0012] In an optional embodiment, the standard section is provided with forklift holes for matching with the forklift forks.

[0013] The wall-hanging tooling trolley provided by this invention has one or more standard sections between its operating platform and lifting section. Depending on actual needs, one or more standard sections can be set to ensure that the operating platform meets the height requirements. A first support arm and a second support arm are set on the main body of the platform to support the wall.

Detailed Implementation

[0016] The terms “first,” “second,” “third,” etc., are used only for distinguishing descriptions and do not indicate a sequence number, nor should they be interpreted as indicating or implying relative importance.

[0017] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0018] In the description of this application, it should be noted that the terms "inner", "outer", "left", "right", "upper", "lower", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this application is in use. They are only for the convenience of describing this application 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. Therefore, they should not be construed as limitations on this application.

[0019] In the description of this application, unless otherwise expressly specified and limited, the terms “set up,” “install,” “connect,” and “link” shall be interpreted broadly, for example, as a fixed connection, a detachable connection, or an integral connection; as a mechanical connection or an electrical connection; as a direct connection or an indirect connection through an intermediate medium; or as a connection within two components.

[0020] The technical solution of this application will now be clearly and completely described with reference to the accompanying drawings.

[0021] Example Reference Figures 1-10 The present invention provides a wall-mounted tooling trolley, comprising an operating platform 100, at least one standard section 200 and a lifting section 300 arranged sequentially from top to bottom; The operating platform 100 includes a platform body 101, on which a first support arm 102 and a second support arm 103 are provided, and a clamping groove 104 is formed between the first support arm 102 and the second support arm 103; the lower end of the hanging wall 500 is inserted into the clamping groove 104, and the upper ends of the first support arm 102 and the second support arm 103 are used to abut against the hanging wall 500.

[0022] In some embodiments, the operating platform 100, standard section 200, and lifting section 300 are arranged sequentially from high to low; the lifting section 300 can extend and retract, thereby increasing the height of the operating platform 100, so that the hanging wall 500 on the operating platform 100 can be raised, and the steel bars on the hanging wall 500 can be accurately inserted into the prefabricated holes at the top, thereby achieving the precise installation of the hanging wall 500.

[0023] The operating platform 100 and the standard section 200 are connected in a detachable manner. Generally, the standard section 200 is connected to the operating platform 100 with bolts, thereby making the standard section 200 and the operating platform 100 firmly connected. Depending on the actual needs, one or more standard sections 200 are set between the operating platform 100 and the lifting section 300. Adjacent standard sections 200 are connected in a detachable manner, generally by bolts to connect two adjacent standard sections 200.

[0024] The standard section 200 and the lifting section 300 are also connected in a detachable manner. After the standard section 200 and the operating platform 100 are assembled, tools such as a forklift are used to move the standard section 200 above the lifting section 300 to achieve the connection and fixation between the standard section 200 and the lifting section 300.

[0025] The lifting section 300 can be raised and lowered. After the wall 500 is moved to the designated position, the lifting section 300 raises the wall 500, thereby completing the hoisting of the wall 500. The wall 500 is T-shaped. After the wall 500 is inserted into the clamping slot 104, the first support arm 102 and the second support arm 103 cooperate to support the wall 500, so that the wall 500 can be assembled on the platform body 101 and can follow the platform body 101 to rise and fall.

[0026] In an optional embodiment, the platform body 101 is further provided with a reinforcing rib 107, one end of which is connected to the platform body 101 and the other end is connected to the first support arm 102. In an optional embodiment, the platform body 101 is further provided with a third support arm 105, which is located on the side of the second support arm 103 away from the first support arm 102. A support plate 106 is provided at the upper end of the third support arm 105. The support plate 106 is connected to the second support arm 103. The support plate 106 and the second support arm 103 form a support surface for supporting the hanging wall 500.

[0027] To ensure the strength of the first support arm 102 and enable it to support the suspended wall 500, multiple reinforcing ribs 107 are provided on one side of the first support arm 102. One end of the reinforcing rib 107 is used to connect to the first support arm 102, and the other end is connected to the platform body 101. The reinforcing ribs 107 form a stable triangular structure between the first support arm 102 and the platform body 101, thereby improving the strength of the first support arm 102.

[0028] A third support arm 105 is provided on one side of the second support arm 103. A support plate 106 is provided on the third support arm 105, and the side of the support plate 106 is connected to the second support arm 103. The upper end face of the support plate 106 and the upper end face of the second support arm 103 form a support surface for supporting the hanging wall 500, ensuring that the hanging wall 500 can be stably supported.

[0029] Reference Figure 2 In an optional embodiment, a protective railing 700 is provided on the platform body 101.

[0030] In an optional embodiment, a ladder 600 is provided on the platform body 101.

[0031] In some embodiments, a guardrail 700 is provided on the platform body 101, which effectively ensures the safety of the staff and prevents the staff from falling off the platform body 101.

[0032] To facilitate staff access to the main platform 101, a ladder 600 is installed on the main platform 101, allowing staff to climb onto the main platform 101.

[0033] Reference Figure 6 and Figure 7 In an optional embodiment, the standard section 200 is provided with forklift holes for matching with the forks of a forklift. To facilitate the movement of the standard section 200, a forklift hole matching the forklift forks is provided on the standard section 200; the forklift inserts its forks into the forklift hole of the standard section 200, which allows the standard section 200 and the operating platform 100 to be moved, the standard section 200 to the lifting section 300, and then the standard section 200 and the lifting section 300 to be connected.

[0034] Reference Figure 1 and Figure 2In an optional embodiment, a movable base 400 is also included, on which the lifting section 300 is disposed. In an optional embodiment, a rotating base 900 is provided on the movable base 400, and the lifting section 300 is provided on the rotating base 900. In an optional embodiment, the lower end of the movable base 400 is provided with guide rail rollers 800. In an optional embodiment, the lifting section 300 is provided with a plurality of lifting components 301, the movable end of the lifting component 301 being used for connection to the rotating base 900.

[0035] Temporary steel or alloy rails (U-shaped or I-beam rails) are laid on the subway platform to guide the movement of the mobile base 400. The rails are fixed to the ground and anchored with expansion bolts or welded to the steel structure foundation beams, and are used in conjunction with guide rollers 800 for sliding operations.

[0036] The movable base 400 is also equipped with a braking device and a limit pin, and a rotating base 900 is provided on the movable base 400. The lifting section 300 is provided on the rotating base 900. The structure of the rotating base 900 is existing technology. The rotating base 900 is provided on the movable base 400, and the lifting section 300 is provided on the rotating base 900. When the lifting section 300 needs to be rotated, the angle of the hanging wall 500 on the operating platform 100 is adjusted so that it can be installed accurately.

[0037] The lifting section 300 is generally equipped with at least four lifting components 301. The lifting components 301 are generally hydraulic cylinders. The movable end of the hydraulic cylinder is connected to the rotating base 900, or the movable end of the hydraulic cylinder is connected to the lifting section 300 and the other end is connected to the rotating base 900. The lifting components 301 are used to raise and lower the lifting section 300, thereby increasing the height of the suspended wall 500. This allows the steel bars on the suspended wall 500 to be inserted into the prefabricated holes at the top. How to install the suspended wall 500 on the roof of the station is existing technology. For details, please refer to the construction method of the suspended wall 500 for prefabricated platform door of the prefabricated station.

[0038] The rotating base 900 is existing technology. The lower end of the rotating base 900 is mounted on the movable base 400, and the lifting section 300 is mounted on the rotating base 900. The rotating base 900 can rotate the lifting section 300, thereby rotating the lifting section 300, the standard section 200, the operating platform 100, and the hanging wall 500, thereby rotating the angle of the hanging wall 500 so that it can correspond to the preset installation position, thereby achieving precise assembly.

[0039] The operating platform 100 is a work platform welded from channel steel or H-beams. The upper surface of the platform body 101 is provided with a checkered steel plate, and the sides are provided with guardrails and ladders 600. The operating platform 100 is connected and fixed to the lower standard section 200 by bolts.

[0040] The standard section 200 is a frame structure made of square tubing, with horizontal and diagonal support ribs. The lower part has horizontal square tubing with forklift holes of standard size spacing, which facilitates the insertion and lifting of forklift forks. Multiple standard sections 200 can be set to meet different installation height requirements; the upper and lower parts are connected to the operating platform 100 and the lifting section 300 by high-strength bolts.

[0041] The lifting section 300 has a similar structure to the standard section 200, but it has a built-in lifting cylinder guide groove structure, which serves as an adjustable component to raise the platform height. It is bolted to the standard section 200 and is vertically lifted by the lifting cylinder system of the lifting assembly 301 under the guidance of the vertical guide column.

[0042] Reference Figure 8 , Figure 9 and Figure 10 After the tracks are pre-laid and positioned at the construction site, the tooling trolley assembles the operating platform 100, at least one standard section 200, and the lifting section 300 in sequence: First, the guide roller 800 mechanism of the movable base 400 is placed on the track to initially complete the directional positioning; then, the rotating base 900 is installed, which is connected to the guide roller 800 mechanism through flange bolts and has an adjustable direction function; next, the standard section 200 is installed. This component is a basic skeleton structure, which uses diagonal bracing to improve stability and is connected and fixed to the lower rotating base 900 through corner bolts and positioning pins; the operating platform 100 is assembled above the standard section 200: the platform has connecting plates at the four corners, which are connected to the top flange of the standard section 200 through high-strength bolts. The main body of the platform 101 is equipped with side guardrails and diagonal braces to enhance lateral stability. During the assembly process, construction personnel should use a crane for auxiliary operation to ensure that the connecting surfaces fit tightly and to correct the levelness and verticality of the platform one by one. After assembly, an integrated rigid frame structure is formed, which provides a supporting foundation for the subsequent installation of the suspended wall 500.

[0043] After the wall-lifting tooling trolley is assembled, the installation of the wall-lifting 500 component can be carried out: First, the wall-lifting 500 is lifted from the temporary storage area to the position directly above the operating platform 100 using lifting equipment. Before lowering the wall-lifting 500, installation accessories such as component pads, positioning pins, and temporary clips are prepared on the operating platform 100. After the wall-lifting 500 is slowly lowered into position, the operators cooperate to complete the alignment guidance and preliminary positioning on the top of the operating platform 100.

[0044] After the wall-mounted section 500 is positioned and installed, using the pre-set forklift holes at the bottom of the standard section 200, the forklift is operated to insert the forks into the square tube slots at the bottom of the standard section 200, lifting it horizontally and slowly pushing it out to achieve a smooth transfer of the standard section 200. After being transported to the initial position of the lifting section 300 (the end entrance of the subway station), the forklift is operated to vertically lift the standard section 200 and align it with the upper part of the lifting section 300 structure, and place it on the upper end of the lifting section 300, thus completing the positioning of all components of the platform screen door wall-mounted fixture trolley.

[0045] The integrated wall-lifting trolley connects to the temporary track system laid in the subway station via a guide rail roller mechanism located on the movable base 400. Operators use traction equipment to guide the trolley smoothly forward from its initial position at the end of the subway station, traversing the station construction area, and moving it to the designated installation position for the platform screen door wall-lifting device 500. Upon reaching the target construction area, the position is locked by a limit device, and the entire wall-lifting trolley enters the operational state.

[0046] The wall-mounted tooling trolley provided by this invention has one or more standard sections 200 between its operating platform 100 and lifting section 300. Depending on actual needs, one or more standard sections 200 can be set so that the operating platform 100 can meet the height requirements. The first support arm 102 and the second support arm 103 set on the platform body 101 cooperate to support the wall 500. The lifting section 300 can raise the operating platform 100, thereby raising the height of the wall 500, achieving precise positioning and temporary fixation of the wall 500, thereby improving construction efficiency, ensuring construction safety, and meeting the technical requirements of high-precision installation.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
