Abstract
Description
[Technical Field]
[0001] This invention relates to the technical field of support structures for slings, and more particularly to a support structure for slings that is designed to transfer stress from the sling to the ceiling, thereby providing a support structure that is easy to carry, safe, and stable, and has the advantage of reducing transportation costs. [Background technology]
[0002] Currently, there are two main methods for transporting heavy loads to high floors: using a crane or using a lifting device. Although a crane can be operated quickly, the cost of dispatching the vehicle is high, and a temporary road occupation permit must be applied for, which is not only cumbersome but also often affects surrounding traffic, making the use of a crane not an ideal option for most private buildings.
[0003] Compared to crane trucks, lifting devices are less expensive and easier to use, but there are always concerns about structural fixation and safety. Most conventional lifting devices are designed to be attached and fixed to parapets, iron bars, or balcony railings, and are supported by the building's structural members on site. However, this method is extremely risky, and especially in the case of old buildings, it is difficult to assess whether the existing structure can withstand the additional load, and the consequences of losing balance and falling can be disastrous.
[0004] In addition, some hanging devices use a "large bracket" design, which increases stability by fixing multiple points inside the balcony, but the device is very large and difficult to store, and users must clear space on the balcony before installation, which is very inconvenient for them. Furthermore, the device itself is not easy to transport, and transporting it to high floors still requires manual labor, which increases the workload.
[0005] For example, Taiwan Patent No. M582038 "Crane" discloses a hanging device that supports a ceiling, the purpose of which is to increase the stability of the entire hanging operation. However, since the structure requires a cross beam to be clamped at the same time, it is limited by the presence of a cross beam inside the building. If there is no beam structure on site, the device cannot be used, which obviously limits the scope of application.
[0006] Therefore, currently available lifting devices on the market rely on the strength of the building's exterior walls or on special structures (e.g., cross beams) for fastening, and both methods have problems such as low flexibility in use and high safety risks. Therefore, how to solve the above-mentioned conventional problems and drawbacks is the direction in which manufacturers involved in businesses related to the applicant of this invention hope to improve. [Prior art documents] [Patent documents]
[0007] [Patent Document 1] Taiwan Patent No. M582038 Specification Summary of the Invention [Problem to be solved by the invention]
[0008] The purpose of this invention is to provide a support structure for a lifting device that utilizes an extension base and support member design that allows users to quickly assemble it on-site and complete the installation of the lifting device only on the ceiling and ground, thereby eliminating the need to damage the building itself and avoiding excessive reliance on special structures, and making it easy to store and carry.
[0009] The present invention further aims to provide a support structure for a sling that utilizes the design of the rear top section and the first traction component to transfer the load stress of the sling to the end of the rear extension component and the ceiling, thereby increasing the support strength and stability of the sling and improving the overall convenience and safety of use. [Means for solving the problem]
[0010] To achieve the above-mentioned objectives, the structure of the present invention comprises an extension base, a support member, a rear top section, a rear adjustment section, at least one force component coupling section, and at least one first traction section. The extension base further comprises a rear extension section, and the support member comprises a main shaft for connecting a sling and a rear support section. The extension base is mounted on the floor, and the rear extension section extends horizontally away from the exterior of the vehicle. The support member is installed upright on the extension base, and the rear support section is mounted on the rear extension section. The rear top section is formed at the upper end of the rear support section, and the rear adjustment section is connected to the rear support section. The force component coupling section is mounted on the main shaft, one end of the first traction section is connected to the force component coupling section, and the other end of the first traction section is mounted on the rear extension section or the rear support section.
[0011] When using this device to operate a lifting device, a user first assembles the extension base and support member between the floor and ceiling. The main shaft of the support member is erected near the parapet, and the rear support member is erected on one side away from the outside. The rear extension member of the extension base is installed between the main shaft and the rear support member, forming a U-shape. The rear adjustment member is then used to adjust the height of the rear support member, pressing the rear top section against the ceiling, while the first traction member pulls and supports the component coupling member. This allows the stress applied to the lifting device connected to the main shaft to be transferred to the end of the rear extension member and the ceiling. Overall, the device is small in volume before assembly, making it easy to store and transport. Furthermore, the device is not subject to environmental conditions during assembly, has wide applicability, and effectively distributes load stress after assembly. [Effects of the Invention]
[0012] The above technology solves the problems that exist in conventional slings, such as the need to rely on structures such as parapets, iron grids, or cross beams for fixation, which means that the source and strength of support force are uncertain and there are safety risks, and the large volume of large slings makes them inconvenient to store and transport, thereby achieving practical advances in the above advantages.

[Figure 9] FIG. 10 is a perspective view of a fourth preferred embodiment of the present invention; DETAILED DESCRIPTION OF THE INVENTION
[0014] Please refer to Fig. 1. Fig. 1 is a perspective view of a first preferred embodiment of the present invention. As can be seen from the figure, the present invention comprises an extension base 1, a support member 2, a rear top portion 221, a rear adjustment component 31, at least one force component coupling portion 212, and at least one first traction component 41.
[0015] The extension base 1 is mounted on the floor and includes a rear extension part 11, which extends horizontally in a direction away from the outside of the room.
[0016] The support member 2 is installed upright on the extension base 1 and includes a main shaft body 21 for connecting the sling 5 and a rear support part 22 provided on the rear extension part 11.
[0017] The rear top portion 221 is formed at the upper end of the rear support component 22 and comes into contact with the ceiling.
[0018] The rear adjustment part 31 is connected to the rear support part 22, so that by adjusting the height of the rear support part 22, the rear top part 221 is pressed against the ceiling.
[0019] At least one force component coupling portion 212 is provided on the main shaft 21 .
[0020] At least one first traction component 41 has one end attached to the force component coupling portion 212 and the other end attached to the rear extension component 11 or the rear support component 22 .
[0021] The extension base 1 is, for example, a rectangular metal rod that is placed flat on the floor. In this embodiment, it is mainly implemented by a rear extension piece 11 that extends linearly from the parapet to the inner wall. The support member 2 is, for example, a metal cylindrical rod that is placed perpendicular to the extension base 1. In this embodiment, the main shaft 21 is located at one end of the rear extension piece 11 close to the parapet and is higher than the parapet, and the rear support piece 22 is located at one end of the rear extension piece 11 close to the inner wall and is close to the height of the corresponding floor. The rear top portion 221 refers to the portion where the upper end of the rear support piece 22 can contact the ceiling. The rear adjustment piece 31 is adjusted by one of a screw-type lifting column, a hydraulic lifting device, a pneumatic lifting device, or a jack. In this embodiment, a screw-type lifting column is used as an example. The first traction element 41 may be a capstan wire, a hook wire, a ratchet belt, a cam clamp, or a fixed connecting rod. In this embodiment, the first traction element 41 is a capstan wire and a hook wire. That is, it includes three elements: a capstan 411, a wire 412, and a hook 413. The capstan 411 is fixed to the rear extension element 11, and the other end of the wire 412 is the hook 413, which is used to connect to the force component coupling element 212. In this embodiment, the force component coupling element 212 is a snap ring. However, the corresponding forms of the above-mentioned elements are merely examples of preferred embodiments, and all forms having equivalent functions are within the scope of the present invention and are not limited to the above-mentioned examples.
[0022] The above explanation allows the structure of the present technology to be understood. By combining this structure in a corresponding manner, a design that transfers the stress of the suspender 5 to the ceiling can be provided, which is easy to carry, safe, and stable, and also has the advantage of reducing transportation costs. Details will be explained below.
[0023] Please refer to Figures 1 to 4. Figures 1 to 4 are perspective views illustrating the implementation of a first preferred embodiment of the present invention. When assembling the above-mentioned components, as can be seen from the figures, the extension base 1 and support member 2 of the present invention do not include the sling 5 and first towing member 41 before assembly. Instead, they consist of multiple long pipe-like structures, such as the rear extension member 11, main shaft 21, rear support member 22, and rear adjustment member 31. This allows them to be easily stored side by side or stacked, occupying a small space. Naturally, the small amount of material and light weight also reduce the burden of transportation.
[0024] Upon arriving at a construction site, such as an apartment balcony, the extension base 1 and support member 2 are first assembled between the floor and ceiling. The main shaft 21 of the support member 2 is erected near the parapet, and the rear support member 22 is erected on one side away from the exterior. The rear extension member 11 of the extension base 1 is installed between the main shaft 21 and the rear support member 22, forming a U-shape. However, since the heights of each building floor vary, the rear adjustment member 31 can be used to adjust the height of the rear support member 22, thereby ensuring that the rear top portion 221 is pressed firmly against the ceiling. In this embodiment, the rear adjustment member 31 is a screw-type lifting column, so it can be extended or retracted simply by rotating the rear support member 22, thereby tightening or loosening the extension base. Naturally, by tightening it upward and simultaneously pressing the extension base 1 downward against the floor, it is possible to prevent it from sliding and shifting. Next, the first traction component 41 is fixed to the rear extension component 11 for the purpose of connecting it to the upper end of the main shaft 21. In this embodiment, the first traction component 41 is a combination of a capstan wire and a hook wire. Therefore, the wire 412 inside the capstan 411 is pulled out, and the hook 413 at the end of the wire 412 is connected to the component force coupling 212 of the main shaft 21. The capstan 411 is then used to tighten the wire 412, thereby completing the support structure of the lifting device 5. Finally, the lifting device 5 is connected to the main shaft 21, and the lifting of the target object can begin.
[0025] In this way, the stress acting on the sling 5 forms a fulcrum of torque T at the joint between the sling 5 and the main shaft 21, and is induced to the rear extension part 11 via the first traction part 41 and the main shaft 21. Furthermore, a second fulcrum of torque is formed at the joint between the rear extension part 11 and the rear support part 22. Of these, the rightward component of the torque T is induced into a leftward tension T x The downward component of the torque T is resisted by the frictional force between the rear extension part 11 and the ground, and is transmitted to the rear support part 22, generating a downward tension force T y is generated and resisted, and is further conducted to the ceiling, resulting in a downward component of the force acting on the ceiling, or the ceiling's reaction force T r The downward component of the torque T is offset by a force that can be interpreted as: This allows the load stress on the suspender 5 to be effectively transferred to the end of the rear extension part 11 and the ceiling. In this way, the installation of the suspender 5 can be completed using the ceiling and the ground, eliminating the need to damage the building itself and avoiding excessive reliance on special structures, while also increasing the support strength and stability of the suspender 5 and improving the overall convenience and safety of use.
[0026] Please refer to Figures 5 and 6. Figures 5 and 6 are perspective views and diagrams illustrating the use of a second preferred embodiment of the present invention. As can be seen from the figures, the main difference between this embodiment and the above-mentioned embodiments is the addition of side supports and support for the top of the main shaft 21 to prevent twisting. Therefore, the extension base 1 includes a side extension 12 located on a side different from the rear extension 11, and the support member 2 includes a side support 23 attached to the side extension 12. The upper end of the side support 23 is formed with a side apex 231, which is connected to a side adjustment 32. The upper end of the main shaft 21 is formed with a front apex 211, which is connected to a front adjustment 33. The force component coupling 212 can be provided in multiple locations, allowing a first traction component 41 and at least one second traction component 42 to be installed simultaneously. The other end of the second pulling element 42 is attached to the side extension element 12 or the side support element 23. The side extension element 12 and the rear extension element 11 have the same structure but are installed perpendicular to the rear extension element 11, and the side support element 23 and the rear support element 22 have the same structure. The definitions of the side top element 231, the front top element 211, and the rear top element 221 correspond to each other, the functions of the side adjustment element 32, the front adjustment element 33, and the rear adjustment element 31 are the same, and the functions of the second pulling element 42 and the first pulling element 41 are the same. In this way, not only is the length of the main shaft 21 increased, but the front top element 211 and the front adjustment element 33 can be used to press against the ceiling. At the same time, a set of side extension parts 12 is added to the side of the extension base 1, and a side support part 23 is installed at one end of the side extension part 12 away from the main shaft body 21. Furthermore, the length of the side support part 23 and the length of the rear support part 22 are the same, and similarly, the length of the side support part 23 can be adjusted using the side adjustment part 32 to press the side top part 231 against the ceiling.
[0027] The action of the main shaft 21 pressing against the ceiling mainly helps the rear support element 22 share stress, thereby increasing the load capacity and preventing damage to the building due to concentrated force at one point. The action of the side support element 23 pressing against the ceiling and the action of the second traction element 42 pulling and supporting are intended to resist lateral torque applied to the main shaft 21. The target of the lifting device 5 is very likely to sway during ascent, and while forward and backward swaying relative to the building is within the tolerance of the main shaft element 21 and rear support element 22, left and right swaying may cause the present invention to warp or slip. Therefore, using the side support element 23 to resist lateral torque effectively solves the above problem.
[0028] In this embodiment, the front adjustment element 33 is exemplified by a jack, the side adjustment element 32 is exemplified by a screw-type lifting column, and the second traction element 42 is exemplified by a combination of a capstan wire and a hook wire. The extension base 1 in this embodiment also includes multiple connecting elements 13, allowing the side extension elements 12 to be connected accordingly depending on the installation direction. The connecting elements 13 are exemplified by three connection ports on a T-shaped square pipe. The connecting element 13 at the bottom end of the straight pipe of the T-shaped square pipe is used to connect the rear extension element 11, and the connecting elements 13 at both ends of the horizontal pipe of the T-shaped square pipe are used to connect the side extension elements 12. Furthermore, the side extension elements 12 can be selectively installed on the left or right end depending on environmental conditions, providing high installation flexibility and without increasing the difficulty of installation due to the addition of the side support elements 23.
[0029] Please refer to Figures 7 and 8. Figures 7 and 8 are perspective views of a third preferred embodiment of the present invention and a diagram showing the components before assembly. As can be seen from the figures, the main difference between this embodiment and the above-mentioned embodiments is that the main shaft 21, rear support 22, and side support 23 are modified to a multi-stage structure, and the front top portion 211, rear top portion 221, and side top portion 231 have increased contact areas with the ceiling. Therefore, the support member 2 is composed of multiple removable fitting pipe members A, and the top end of the support member 2 is equipped with at least one extended contact portion B. In this embodiment, the fitting pipe members A can be connected using a quick-release method such as a clasp, ball spring, compression, or fitting. At least two fitting pipe members A constitute a set of the main shaft 21, rear support 22, or side support 23. The more parts are disassembled, the easier it is to store and carry, and they can be directly placed in a box. However, considering structural strength, the length of each fitting pipe A is preferably approximately 1 to 2 meters. In this embodiment, the fitting pipe A is exemplified by a structure connected with a stopper. In this embodiment, the extended contact portion B is a contact structure installed on the front apex portion 211, the rear apex portion 221, and the side apex portion 231. It can be T-shaped, radial, flank-shaped, disc-shaped, or inverted cone-shaped, and can be any shape as long as its area is larger than the cross-sectional area of the support member 2. In this embodiment, the extended contact portion B of the main shaft 21 is T-shaped, for example, which allows for easy installation of the component force coupling portion 212. The extended contact portions B of the rear support member 22 and the side support member 23 are exemplified by a disc-shaped, which allows a large area to contact the ceiling, thereby increasing the strength of the entire structure, preventing tilting of the support member 2, and providing the effect of stably distributing stress.
[0030] In addition, the first traction element 41 and the second traction element 42 in this embodiment are exemplified as horizontal fixed connecting rods, and horizontal fixed connecting rods are directly installed between the main shaft 21 and the rear support element 22 or between the main shaft 21 and the side support element 23. Since the overall function is the same, the stress adjustment and distribution operations will not be described in detail.
[0031] Please also refer to FIG. 9. FIG. 9 is a perspective view of a fourth preferred embodiment of the present invention. As can be seen from the figure, the main difference between this embodiment and the above-mentioned embodiments is that the extension base 1 is additionally provided with a wall-mounting function. Therefore, the extension base 1 can abut against a wall by providing at least one lateral adjustment element 111. The lateral adjustment element 111 is, for example, a horizontally installed screw-type lifting column. In this embodiment, both front and rear ends are simultaneously installed on the rear extension element 11, thereby allowing the extension base 1 to press against the inner wall and parapet. Its main function is the same as that of the side support elements 23, which is to resist lateral torque applied to the main shaft 21 and prevent it from shifting or sliding. At the same time, the frictional force generated when pressing against the wall surface can be used to share some of the load stress.
[0032] Furthermore, the rear adjustment component 31 and the side adjustment component 32 in this embodiment are exemplified by hydraulic lifting devices or pneumatic lifting devices, and the overall function is the same, so the stress adjustment and distribution operation will not be described in detail.
