Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment technology for building construction, specifically to a collaborative and simple transportation device for confined spaces. Background Technology

[0002] In the construction of large public buildings, such as cultural centers and stadiums, it is common to encounter situations where long, narrow components, such as skylight joists, need to be installed inside complex structures or on roofs. These construction areas are often surrounded by beams, columns, and floor slabs, creating a working environment with limited height or width. Traditional large lifting machinery, such as tower cranes and truck cranes, often cannot reach or cover these areas due to limitations in boom span, turning radius, or site access, resulting in materials being unable to be delivered or loaded. Relying entirely on manual labor for material handling presents significant problems, including high labor intensity, low efficiency, and high safety risks associated with working at heights, severely hindering construction progress.

[0003] Therefore, there is an urgent need for a simple device that can adapt to narrow spaces, is easy to move, does not rely on external energy, and can provide stable lifting support to solve the problem of transporting and installing medium-sized components in confined spaces. Summary of the Invention

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a simple collaborative transportation device for confined spaces. The device has a stable structure, is flexible in movement, is easy to assemble and disassemble, and requires no external power. It is particularly suitable for solving the problem of horizontal transportation and precise positioning of skylight keel and other poles in areas that cannot be covered by conventional lifting machinery.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A simple, collaborative transportation device for confined spaces includes: a pair of outriggers, each outrigger comprising a vertically arranged outrigger body and a triangular stabilizing support structure located at the lower part of the outrigger body; a main beam, a long rectangular steel structure, erected between the two outriggers; an inclined support arm, one end of which is fixedly connected to the upper end of the main beam, and the other end of which is fixedly connected to the upper end of the outrigger body; lifting lugs located at the lower ends of both sides of the main beam for suspending lifting tools; and casters located at the bottom of the triangular stabilizing support structure for enabling overall movement of the device. Furthermore, lifting lugs are provided on both sides of the main beam and at the back of the connection points between the support arm and the main beam.

[0006] Furthermore, lifting lugs are provided on both sides of the main beam and on the back of the connection point between the support arm and the main beam.

[0007] Furthermore, the main body of the outrigger and the main beam are made of galvanized square steel of 200×200×5mm, the total height of the outrigger is 2000mm, and the length of the main beam is 6000mm.

[0008] Furthermore, the triangular stable support structure is constructed by welding square steel, and the bottom of the triangular stable support structure is equipped with the caster wheel, which has a diameter of 125mm and a wheel surface width of 50mm.

[0009] Furthermore, the device is a modular and detachable structure, suitable for horizontal transportation and high-altitude installation of skylight keel in confined spaces. Beneficial effects

[0010] 1. Zero energy consumption Completely independent of traditional energy sources such as electricity and fuel oil, it reduces carbon emissions at the source, aligning with green construction requirements. Simultaneously, it eliminates energy procurement and equipment purchase and maintenance costs, avoids energy-related safety hazards, and lowers overall costs and risks.

[0011] 2. Easy to make The raw materials are common market items, making procurement convenient. The production process is simple, requiring no complex techniques or specialized equipment. Ordinary construction workers can operate it after simple training. It can be produced on-site immediately and flexibly adjusted, reducing the risk of transportation losses and project delays.

[0012] 3. Overcoming limited space constraints Some components support modular disassembly and assembly, eliminating the need for large-scale site modifications and solving the problem of limited construction sites for skylights and the inability of conventional machinery to reach the work area.

[0013] 4. Good results when used No mechanical scheduling is required; its operating efficiency is superior to some conventional machines; it is suitable for scattered operations; it reduces surrounding interference and has a high safety factor. Attached Figure Description

[0016] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. It should be noted that the specific embodiments described herein are only for explaining this utility model and are not intended to limit this utility model.

[0017] like Figure 1As shown, the present invention provides a collaborative simple transportation device for confined spaces, the core load-bearing frame of which consists of a pair of legs 1 and a main beam 2.

[0018] The outrigger 1 is welded from galvanized square steel and consists of an upper outrigger body 4 and a lower triangular stabilizing support structure 5. The outrigger body 4 is a vertically arranged square steel tube, and the triangular stabilizing support structure 5 is formed by welding multiple sections of square steel diagonally to both sides of the lower end of the outrigger body 4, greatly enhancing the outrigger's resistance to lateral tipping. At the base corner of each triangular stabilizing support structure 5, casters 3 are bolted on, enabling the device to move in all directions.

[0019] The main beam 2 is also made of galvanized square steel and is horizontally erected between the two legs 1. It can be connected to the legs 1 by welding or high-strength bolts. In order to improve the lateral stability of the main beam 2 and the rigidity of the overall structure, support arms 6 are obliquely welded between the upper sides of the main beam 2 and the upper end of the leg body 4, forming a stable triangular load-bearing frame.

[0020] Lifting lugs 7 are welded to the lower ends of both sides of the main beam 2. These lugs 7 can be used to suspend lifting tools such as low-headroom manual hoists and electric hoists. As a more preferred embodiment, lifting lugs 7 are welded to the back of both sides of the main beam 2 and at the connection point between the support arm 6 and the main beam 2. These lugs 7 can be used to suspend balance guy ropes or auxiliary lifting points, further increasing the flexibility of use.

[0021] In this embodiment, the total height of the support leg 1 (including the triangular structure) is 2000mm, the length of the main beam 2 is 6000mm, and the material is 200×200×5mm galvanized square steel. The caster wheel 3 is a 125mm diameter polyurethane wheel with strong load-bearing capacity.

[0022] In use, construction workers can first transport the entire device or its modules to the work floor and quickly assemble it at the starting point where the keel needs to be transported. The hoist is then attached to the lifting lug 7, hooking onto the skylight keel, and the keel is lifted to a suitable height by manually pulling the hoist chain. Then, one or two people push the device, using the casters 3 to transport the keel horizontally directly below the installation point. Finally, the hoist is used for final fine-tuning, raising, lowering, and positioning of the keel, which is then installed and secured by high-altitude workers. The entire process requires no electricity, is highly mobile, and solves the problem of transporting and positioning long materials in confined spaces, addressing the "last mile" challenge.

[0023] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the protection scope of this utility model.
