Description

Technical Field

[0001] This application relates to the technical field of hydraulic lifting platforms, and in particular to a tracked hydraulic lifting platform for large-span spatial steel structure construction. Background Technology

[0002] In current construction of large-span spatial steel structures, the lifting, positioning, and welding of steel components mainly rely on traditional lifting machinery or scissor lift platforms. The use of scaffolding requires repeated erection and dismantling according to the position of the steel beams, which greatly increases construction costs. Truck cranes are suitable for open spaces, but are difficult to operate when indoor spaces are limited.

[0003] The existing publication number CN207404794U, entitled "A Hydraulic Lifting Platform," includes a rectangular base, a lifting cylinder, and a rectangular lifting platform. The bottom of the lifting cylinder is fixed to the rectangular base, and the upper end of the lifting cylinder is fixedly connected to the rectangular lifting platform. It also includes four telescopic guide components and a water tank. A telescopic guide component is fixed to each of the four corners of the rectangular base, and the top of each telescopic guide component is fixedly connected to the rectangular lifting platform. Extension plates for mounting the water tank are integrally provided at both ends of the rectangular base, and the water tank is fixed to the upper surface of the extension plates. Each telescopic guide component includes an upper cylinder body, a lower cylinder body, a piston rod, a piston, an inlet and outlet port, a three-way connector, a one-way valve, a shut-off valve, an inlet pipe, and an outlet pipe. This utility model has the following advantages: it solves the problem of skewing during the lifting process; even if the hydraulic system's oil supply system or the hydraulic cylinder leaks, the lifting platform will not descend on its own, ensuring the safety of personnel performing high-altitude operations.

[0004] Regarding the aforementioned technologies, the inventors discovered that although the hydraulic lifting platform is highly flexible, the overall length of the large-span spatial steel structure is quite wide, while the width of the lifting platform is limited, making it impossible to lift the entire large-span spatial steel structure. Multiple lifting devices need to be activated simultaneously to support the large-span spatial steel structure. During installation, multiple devices need to work together and must be strictly synchronized, otherwise it is easy to cause the components to become unbalanced. In addition, the coordination operation steps are cumbersome and the operation is difficult. Utility Model Content

[0005] To overcome the limitations of existing large-span spatial steel structures, which have a relatively long overall length and a limited width of the lifting platform, making it impossible to lift the entire large-span spatial steel structure, requiring multiple lifting devices to be activated simultaneously to support the large-span spatial steel structure, and necessitating strict synchronization control when multiple devices work together during installation to avoid component imbalance, as well as complicated coordination procedures and high operational difficulty, this application provides a crawler-type hydraulic lifting platform for the construction of large-span spatial steel structures.

[0006] The technical solution provided in this application for a tracked hydraulic lifting platform for large-span spatial steel structure construction is as follows:

[0007] A tracked hydraulic lifting platform for large-span spatial steel structure construction includes a tracked chassis, a scissor frame, and a lifting component. The scissor frame is hinged to the top surface of the tracked chassis, and a hydraulic rod is hinged to one end of the top surface of the tracked chassis. The top end of the hydraulic rod is hinged to the other side of the top of the scissor frame. The lifting component includes a lifting frame, an extension slide frame, and a lifting slide frame. The lifting frame is horizontally set on the top surface of the scissor frame, and one end of the bottom surface of the lifting frame is hinged to one end of the top surface of the scissor frame. A slide bar is horizontally fixed to the other side of the top surface of the scissor frame, and the slide bar on the scissor frame is horizontally slidably assembled with the other side of the bottom surface of the lifting frame. Extension slide frames are horizontally slidably assembled at both ends of the lifting frame, and lifting slide frames are horizontally slidably assembled within the extension slide frames. Multiple support members are vertically fixed to the top surfaces of the lifting frame, extension slide frames, and lifting slide frames.

[0008] By adopting the above technical solution, during use, the extended sliding frames on both sides of the sliding lifting frame expand outward laterally according to the length of the large-span spatial steel structure, simultaneously driving the lifting sliding frame to extend outward, thus extending the length of the lifting component laterally. This meets the support length requirements of the large-span spatial steel structure. Simultaneously, during support, the hydraulic rod extends, pushing the scissor bracket to extend on the tracked chassis, pushing the lifting component upward, and lifting the large-span spatial steel structure for later installation. This eliminates the need for multiple lifting devices to simultaneously support the large-span spatial steel structure, avoiding the need for strict synchronization control during installation, which can easily lead to component imbalance. Furthermore, it avoids the cumbersome coordination steps and high operational difficulty associated with multiple devices working together during installation. This significantly improves the ease of operation for lifting and raising large-span spatial steel structures.

[0009] Optionally, two guide rail frames are symmetrically and horizontally fixed on both ends of the lifting frame, and multiple guide rail wheels are horizontally rotatably connected on the upper and lower end faces inside the two guide rail frames.

[0010] By adopting the above technical solution, the two guide rail frames fixed at both ends of the lifting frame, and the multiple guide rail wheels connected by the horizontal rotation inside the two guide rail frames, facilitate the horizontal lateral support and extension slide frame for lateral movement guidance, and facilitate the expansion of the lateral movement extension guide lifting component.

[0011] Optionally, locking strips are horizontally fixed on both vertical end faces of the extended slide frame, and the locking strips are inserted into the guide rail frame, and the locking strips are correspondingly engaged with multiple guide rail wheels.

[0012] By adopting the above technical solution, the locking strips on both sides of the extended slide frame are inserted into the guide rail frame, and the locking strips are correspondingly engaged by multiple guide rail wheels, which facilitates the expansion direction and stability of the lateral extension guide lifting component.

[0013] Optionally, a bidirectional screw is horizontally rotatably connected to the middle of the lifting frame, and a rotating pull frame is horizontally fixed at one end of the extended slide frame near the lifting frame, with the rotating pull frame and the bidirectional screw threaded through and assembled together.

[0014] By adopting the above technical solution, when the extended slide frame moves laterally in the lifting frame, the rotating bidirectional screw rotates, and the thread of the bidirectional screw drives the rotating pull frame at the end of the extended slide frame. The lateral movement pushes the extended slide frame to move laterally outward in the lifting frame, which is suitable for lifting components to support the width requirements of large-span spatial steel structures.

[0015] Optionally, the inner sides of the extension slide frame are horizontally provided with slide grooves, and the inner side of the extension slide frame is horizontally rotatably connected with an extension screw.

[0016] By adopting the above technical solution, the slide groove in the extended slide frame is used for lateral guidance to lift the slide frame for movement. Then, the extension screw in the extended slide frame is rotated to push the lifting slide frame to slide, which is suitable for lifting components to meet the width requirements of large-span spatial steel structures.

[0017] Optionally, the lifting carriage has a threaded hole through which a horizontal thread passes, and the threaded hole is assembled with the threaded extension screw, so that the lifting carriage is horizontally slidably assembled in the slide groove of the extension frame.

[0018] By adopting the above technical solution, the rotating extension screw thread drives the lifting slide to move laterally in the slide groove of the extension slide frame, which facilitates the lateral expansion of the width support requirements of large-span space steel structures.

[0019] Optionally, the support includes a stud and a screw tube. The bottom end of the screw tube is fixed to the top surface of the lifting component, and a stud is assembled with vertical threads in the screw tube. The top end of the stud is horizontally rotatably connected to a support.

[0020] By adopting the above technical solution, according to the requirements of supporting large-span spatial steel structures, the rotating stud moves vertically in the screw tube, pushing the support to support the large-span spatial steel structure, which is used to adjust the height requirements of the support for large-span spatial steel structures.

[0021] Optionally, both ends of the tracked chassis are vertically and symmetrically fixed with supporting hydraulic rods, and the bottom end of the supporting hydraulic rods is fixed with a fixing plate.

[0022] By adopting the above technical solution, in order to facilitate the rapid movement and adjustment of the installation position of the large-span spatial steel structure in the later stage, the tracked chassis is used to move and adjust the installation position of the large-span spatial steel structure. Then, the stability of the large-span spatial steel structure is supported by the installation, and the hydraulic rod of the support is activated to extend and push the fixed plate to lift the tracked chassis, thus ensuring the stability of the tracked chassis in supporting the installation of the large-span spatial steel structure.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] During use, based on the length of the large-span spatial steel structure, the extended sliding frames on both sides of the sliding lifting frame move laterally outward, simultaneously driving the lifting sliding frame to extend outward, thus extending the length of the lifting component laterally. This accommodates the support length requirements of the large-span spatial steel structure. Simultaneously, during support, the hydraulic rod extends, pushing the scissor bracket to extend on the tracked chassis, pushing the lifting component upward, and lifting the large-span spatial steel structure for later installation support. This eliminates the need for multiple lifting devices to simultaneously support the large-span spatial steel structure, avoiding the need for strict synchronization control during installation, which can easily lead to component imbalance and cumbersome coordination procedures, significantly improving the ease of operation for lifting and raising large-span spatial steel structures.

[0031] The present application will be further described in detail below with reference to the accompanying drawings.

[0032] This application discloses a tracked hydraulic lifting platform for large-span spatial steel structure construction. (Refer to...) Figure 1 , Figure 2 , Figure 3 and Figure 4A tracked hydraulic lifting platform for large-span spatial steel structure construction includes a tracked chassis 1, a scissor frame 2, and a lifting component 4. The scissor frame 2 is hinged to the top surface of the tracked chassis 1, and a hydraulic rod 3 is hinged to one end of the top surface of the tracked chassis 1. The top end of the hydraulic rod 3 is hinged to the other side of the top of the scissor frame 2. The lifting component 4 includes a lifting frame 41, an extension slide frame 45, and a lifting slide frame 46. The lifting frame 41 is horizontally positioned on the top surface of the scissor frame 2. One end of the bottom surface of the lifting frame 41 is hinged to one end of the top surface of the scissor bracket 2. A slide bar is horizontally fixed on the other side of the top surface of the scissor bracket 2, and the slide bar on the scissor bracket 2 is horizontally slidably assembled with the other side of the bottom surface of the lifting frame 41. Both ends of the lifting frame 41 are horizontally slidably assembled with an extension slide frame 45, and a lifting slide frame 46 is horizontally slidably assembled in the extension slide frame 45. Multiple support members 5 are vertically fixed on the top surfaces of the lifting frame 41, the extension slide frame 45 and the lifting slide frame 46.

[0033] By adopting the above technical solution, during use, based on the length of the large-span spatial steel structure, the extension slide frames 45 on both sides of the sliding lifting frame 41 move laterally outward, simultaneously driving the lifting slide frame 46 to extend outward, and laterally extending the length of the lifting component 4, which meets the support length requirements of the large-span spatial steel structure. At the same time, during support, the hydraulic rod 3 is activated to extend, pushing the scissor bracket 2 to extend on the crawler chassis 1, pushing the lifting component 4 upward, and lifting the large-span spatial steel structure for later installation support. This eliminates the need for multiple lifting devices to start simultaneously to support the large-span spatial steel structure, avoiding the problem of strict synchronous control required when multiple devices work together during installation, which could easily lead to component imbalance, as well as cumbersome coordination steps and high operational difficulty. This improves the ease of operation for lifting and raising the large-span spatial steel structure.

[0034] Reference Figure 4 and Figure 5Two guide rail frames 42 are symmetrically and horizontally fixed on both ends of the lifting frame 41, and multiple guide rail wheels 43 are horizontally rotatably connected to the upper and lower end faces of the two guide rail frames 42. The two guide rail frames 42 fixed at both ends of the lifting frame 41, with the multiple guide rail wheels 43 horizontally rotatably connected inside the two guide rail frames 42, facilitate the horizontal lateral support and guidance of the extension slide frame 45 for lateral movement, thus facilitating the expansion of the lateral extension guide lifting component 4. Two retaining strips 454 are horizontally fixed on the vertical end faces of both sides of the extension slide frame 45, and the retaining strips 454 are inserted into the guide rail frames 42, correspondingly engaging with the multiple guide rail wheels 43. The retaining strips 454 on both sides of the extension slide frame 45, inserted into the guide rail frames 42 and correspondingly engaged with the multiple guide rail wheels 43, facilitate the expansion direction and stability of the lateral extension guide lifting component 4. A bidirectional screw 44 is horizontally rotatably connected to the middle of the lifting frame 41. A rotating pull frame 451 is horizontally fixed to one end of the extension slide frame 45 near the lifting frame 41, and the rotating pull frame 451 is threadedly connected to the bidirectional screw 44. When the extension slide frame 45 moves laterally in the lifting frame 41, the bidirectional screw 44 rotates, and the threaded bidirectional screw 44 drives the rotating pull frame 451 at the end of the extension slide frame 45. The lateral movement pushes the extension slide frame 45 to move laterally outward in the lifting frame 41, which is suitable for the lifting component 4 to support the width requirements of large-span spatial steel structures.

[0035] Reference Figure 4 and Figure 5 The extension slide frame 45 has horizontally opened grooves 453 on both sides inside, and an extension screw 452 is horizontally rotatably connected inside the extension slide frame 45. In use, the grooves 453 in the extension slide frame 45 are used to guide the movement of the lifting slide 46 laterally. Then, rotating the extension screw 452 in the extension slide frame 45 pushes the lifting slide 46 to slide, which is suitable for the lifting component 4 to support the width of large-span spatial steel structures. A threaded hole 461 is opened on the lifting slide 46, and the threaded hole 461 is threadedly assembled with the extension screw 452. The lifting slide 46 is horizontally slidably assembled in the grooves 453 of the extension slide frame 45. Rotating the extension screw 452 drives the lifting slide 46 to move laterally in the grooves 453 of the extension slide frame 45, which facilitates the lateral expansion of the support requirements for the width of large-span spatial steel structures.

[0036] Reference Figure 5 The support component 5 includes a stud 51 and a threaded tube 52. The bottom end of the threaded tube 52 is fixed to the top surface of the lifting component 4, and the stud 51 is vertically threaded into the threaded tube 52. The top end of the stud 51 is horizontally rotatably connected to a support 53. Based on the requirements for supporting a large-span spatial steel structure, rotating the stud 51 allows it to move vertically within the threaded tube 52, pushing the support 53 to support the large-span spatial steel structure, thus adjusting the height required for supporting the large-span spatial steel structure.

[0037] Reference Figure 3Both ends of the tracked chassis 1 are vertically and symmetrically fixed with supporting hydraulic rods 11, and the bottom end of the supporting hydraulic rods 11 is fixed with a fixed plate 12. In order to facilitate the rapid movement and adjustment of the installation position of the large-span spatial steel structure in the later stage, the tracked chassis 1 is used to move and adjust the installation position of the large-span spatial steel structure. Then, the stability of the large-span spatial steel structure support is installed. The supporting hydraulic rods 11 are activated to extend and push the fixed plate 12 to lift the tracked chassis 1, thus ensuring the stability of the tracked chassis 1 in supporting the installation of the large-span spatial steel structure.

[0038] The implementation principle of a tracked hydraulic lifting platform for large-span spatial steel structure construction according to the embodiment of this application is as follows: During use, when the extension slide frame 45 moves laterally in the lifting frame 41 according to the length of the large-span spatial steel structure, the double-acting screw 44 rotates, and the double-acting screw 44 drives the rotating pull frame 451 at the end of the extension slide frame 45 to move laterally. The lateral movement pushes the extension slide frame 45 to move laterally outward in the lifting frame 41. The extension slide frames 45 on both sides of the sliding lifting frame 41 move laterally and expand outward. The rotation of the extension screw 452 drives the lifting slide frame 46 to move laterally in the slide groove 453 of the extension slide frame 45, and at the same time drives the lifting slide frame 46 to extend outward, and laterally extends the length of the lifting component 4 to meet the support length requirements of the large-span spatial steel structure. At the same time, when supporting, the hydraulic rod 3 is activated to extend, pushing the scissor bracket 2 to extend on the tracked chassis 1, pushing the lifting component 4 to rise, and lifting the large-span spatial steel structure to rise for later installation support.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
