Description

Technical Field

[0001] This invention belongs to the field of construction engineering technology, specifically a multi-purpose lifting platform for high-pile wharves. Background Technology

[0002] During the cast-in-place construction of the upper crossbeam of a high-pile wharf, difficulties often arise due to the narrow working surface of the lower crossbeam. These include the lack of vertical access from the longitudinal beams to the lower crossbeam working surface, the narrow working surface above the lower crossbeam, and other challenges encountered during the installation of the upper crossbeam reinforcement and the dismantling of the formwork. These are common difficulties in the current water transport engineering industry during the cast-in-place construction of the upper crossbeam of a high-pile wharf and urgently need to be resolved.

[0003] In view of this, a multi-purpose lifting platform for high-pile wharves is proposed. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0005] Given the following technical problems in the existing technology: During the cast-in-place construction of the upper crossbeam of a high-pile wharf, due to the narrow working surface of the lower crossbeam, difficulties often arise during the installation of upper crossbeam reinforcement and the installation and removal of formwork. These problems include the lack of vertical access from the longitudinal beam to the lower crossbeam working surface, the construction passage between longitudinal beams, and the narrow working surface above the lower crossbeam. These are common difficulties in the cast-in-place construction of the upper crossbeam of a high-pile wharf in the current water transport engineering industry and urgently need to be solved.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a multi-purpose lifting platform for high-pile wharves, comprising a crossbeam, a vertical support beam, and a working platform;

[0007] The number of crossbeams is one pair, and the area between the pair of crossbeams is a construction passage. A longitudinal beam is fixedly installed below the pair of crossbeams, and the number of longitudinal beams is one pair. The passage scaffolding boards are jointly installed on the pair of crossbeams.

[0008] One of the crossbeams has a vertical support beam that moves through it. A working platform is installed at the bottom of the vertical support beam. A reinforcing diagonal brace is installed at the connection between the working platform and the vertical support beam. The reinforcing diagonal brace is used to support and stabilize the vertical support beam.

[0009] As a preferred technical solution for a multi-purpose lifting platform for high-pile wharves, one of the crossbeams is provided with a back lug, and the working platform is provided with a front lug.

[0010] As a preferred technical solution for a multi-purpose lifting platform for high-pile wharves, a hand-operated hoist is provided on both the back lug and the front lug.

[0011] As a preferred technical solution for a multi-purpose lifting platform for high-pile wharves, the vertical support beams are installed in pairs, and a detachable protective short chain is installed in the middle of the pair of vertical support beams.

[0012] As a preferred technical solution for a multi-purpose lifting platform for high-pile wharves, one of the crossbeams has a half-retractable guardrail movably installed on its upper surface, while the other crossbeam has a fixed guardrail installed on its upper surface.

[0013] As a preferred technical solution for a multi-purpose lifting platform for high-pile wharves, the ends of the pair of longitudinal beams extending from the transverse beams are equipped with foot anchors.

[0014] The beneficial effects of this invention are:

[0015] 1. This device, through the combination of a liftable work platform and a construction walkway, significantly expands the working area for the cast-in-place construction of the high-pile wharf beams. The work platform is raised and lowered using a hand-operated hoist, adapting to different construction height requirements and facilitating the smooth progress of processes such as rebar tying, formwork installation and dismantling, and concrete pouring. Compared to traditional fixed platforms, this device offers greater flexibility and effectively shortens the construction cycle.

[0016] 2. The device is equipped with a semi-retractable guardrail, a fixed guardrail, and a detachable short safety chain, providing multiple safety guarantees for construction workers when working at heights and passing through passageways, reducing the risk of falls;

[0017] 3. This device establishes a construction passageway between a pair of crossbeams, connecting various construction areas via scaffold boards, ensuring smooth movement of construction personnel between different passageways. This design not only improves the continuity of the construction area but also facilitates the transportation of personnel and materials, optimizing on-site construction organization.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0026] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0027] Example, refer to Figure 1 A multi-purpose lifting platform for high-pile wharves includes a crossbeam 2, a vertical support beam 3, and a working platform 6;

[0028] There is a pair of crossbeams 2, and a construction passage is between the pair of crossbeams 2. A longitudinal beam 1 is fixedly installed below the pair of crossbeams 2. There is a pair of longitudinal beams 1, and a passage scaffold board 14 is installed on the pair of crossbeams 2.

[0029] One of the crossbeams 2 has a vertical support beam 3 that runs through it for lifting and lowering. A working platform 6 is installed at the bottom of the vertical support beam 3. A reinforcing brace 5 is installed at the connection between the working platform 6 and the vertical support beam 3. The reinforcing brace 5 is used to support and stabilize the vertical support beam 3. By supporting the vertical support beam 3 with the reinforcing brace 5, the working platform 6 is ensured to remain stable during lifting and lowering, reducing the risk of swaying or tilting.

[0030] A foot 11 is installed at the end of the crossbeam 2 extending from a pair of longitudinal beams 1. The height of the foot 11 is designed to be higher than the reserved steel bars of the precast components of the dock, to ensure that the device is placed stably and to avoid instability caused by interference from the components during construction.

[0031] One of the crossbeams 2 has a back hanging ear 10 installed on its back, and a front hanging ear 8 is installed on the working platform 6. A hand chain hoist 4 is installed on both the back hanging ear 10 and the front hanging ear 8.

[0032] The number of vertical support beams 3 is one pair, and a detachable protective short chain 9 is installed in the middle of the pair of vertical support beams 3;

[0033] One of the crossbeams 2 has a retractable half-side guardrail 12 installed on its upper surface, while the other crossbeam 2 has a fixed guardrail 13 installed on its upper surface.

[0034] This implementation allows for the following: During the construction of the crossbeams on the high-pile wharf, construction operations are required for processes such as reinforcing steel, formwork, and concrete pouring.

[0035] The first step is to use a crane to place the device on the high-pile wharf beam, so that the longitudinal beam 1 is placed on the beam of the high-pile wharf. When the working platform 6 is lowered, the part near the foot 11 can rest on the concrete side of the lower cross beam. At this time, the height of the foot 11 is higher than the reserved steel bars of the wharf prefabricated components. Some walkway scaffold boards 14 are added above the pre-embedded steel bars between each construction passage to ensure the continuity between each construction passage.

[0036] The second step is for personnel to use the construction passage on the right to facilitate passage between the erected beams and slabs;

[0037] Third step: When personnel need to carry out construction on the upper beam, the half-retractable guardrail 12 can be used to retract part of the guardrail to the other side, allowing personnel to pass between the construction passage and the lifting platform 6. After the personnel have passed, the half-retractable guardrail 12 can be pulled out to restore the protective function.

[0038] Fourth, by adjusting the hand chain hoist 4, the operator can raise and lower the work platform 6, thus expanding the construction work area and enabling the smooth implementation of construction work such as steel reinforcement binding, formwork installation and dismantling, and concrete pouring for the cast-in-place upper beam of the high-pile wharf.

[0039] It should be understood that numerous specific implementation decisions can be made during the development of any actual implementation method, and in any engineering or design project. Such development efforts may be complex and time-consuming, but for those of ordinary skill in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0040] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
