Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a high-altitude steel structure lifeline installation device. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. Generally, steel structures require rust removal, galvanizing, or painting, and regular maintenance. The installation and maintenance of steel structures typically involve working at heights, especially roof steel structure installations.

[0003] Currently, lifelines are generally used to protect personnel working at heights in construction, in order to improve the safety factor of such workers. Common steel structure lifelines are made by welding steel brackets onto steel beams, and then installing steel wire ropes on the brackets. However, this installation method cannot adjust the position of the lifeline according to the needs of the operation, which means that multiple steel brackets need to be welded when working in different locations on the steel structure, increasing construction costs and reducing construction efficiency.

[0004] In the prior art, patent publication number CN 214659019 U discloses a lifeline system for high-altitude operations on a steel truss, including a lifeline support and a lifeline. The lifeline support includes a support, a vertical pole, and a lifeline limiting plate. The support is set on the steel truss, and the vertical pole is set on the top of the support. The support has a limiting groove, and the flange plate of the steel truss is set in the limiting groove. The support has a first fixing bolt, and the top surface of the support has a first nut. The first nut is welded to the top surface of the support, and the first fixing bolt is threaded into the first nut. The first fixing bolt extends into the limiting groove and fixes the flange plate of the steel truss. This device allows the support to be fixed to the flange plates of steel trusses of different thicknesses. However, each time the installation position of the lifeline system is adjusted, it is necessary to manually tighten the first fixing bolt at high altitude, move the lifeline system, and then tighten the first fixing bolt again to fix it. Moreover, when the lifeline system needs to be adjusted, workers need to work at high altitude. At this time, other installation devices need to be erected to ensure the safety of the workers before the position of the lifeline system can be adjusted. The overall operation steps are relatively complicated, the construction efficiency is low, and there are certain safety risks for workers when moving the lifeline system.

[0005] In view of this, it is necessary to design a high-altitude steel structure lifeline installation device to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a high-altitude steel structure lifeline installation device that can automatically and detachably deploy lifelines according to operational needs, improve construction efficiency while ensuring the safety of workers, and also ensure that the lifeline poles are firmly connected to the steel structure.

[0007] To achieve the above-mentioned objectives, the present invention provides a high-altitude steel structure lifeline installation device, comprising:

[0008] Steel structure;

[0009] A tracked trolley is mounted on the upper surface of a steel structure, and a lifeline upright is installed on the tracked trolley;

[0010] The lifting structure consists of two lifting structures symmetrically arranged along the axial direction of the steel structure. One end of each lifting structure is connected to the tracked trolley, and the other end is routed to the lower surface of the steel structure to connect to a limit block.

[0011] The control system is used to control the movement of the tracked trolley and the operation of the lifting structure;

[0012] When the lifting structure moves the limiting block to be close to the bottom surface of the steel structure, the tracked trolley, the lifting structure, and the positioning block together form a clamping structure, which fixes the tracked trolley to the steel structure. When the lifting structure moves the limiting block away from the bottom surface of the steel structure, the clamping state is released, and the tracked trolley can move freely relative to the steel structure.

[0013] As a further improvement of the present invention, the lifting structure is connected to the side of the tracked trolley, so that the lifting structure is suspended on the side of the steel structure.

[0014] As a further improvement of the present invention, the lifting structure includes a box with an internal receiving cavity, a lifting assembly is provided inside the box, and a steering rod extending to the lower surface of the steel structure is connected to the output end of the lifting assembly.

[0015] As a further improvement of the present invention, the lifting assembly includes a screw, a slider disposed on the screw, and a drive member for driving the screw to rotate.

[0016] As a further improvement of the present invention, guide grooves are provided on both sides of the inside of the box, and a movable plate connected to the slider is connected between the two guide grooves.

[0017] As a further improvement of the present invention, the bottom of the housing is provided with a through groove running vertically through the bottom, and the steering rod includes a vertically connected vertical plate and a horizontal plate, the vertical plate passing through the through groove and connected to the moving plate.

[0018] As a further improvement of the present invention, the limiting block is disposed at the end of the horizontal plate away from the vertical plate.

[0019] As a further improvement of the present invention, the control system is mounted on the tracked vehicle and includes a processor and a power supply.

[0020] As a further improvement of the present invention, the tracked vehicle is also equipped with a monitoring structure to observe the number of safety belts located on the lifeline.

[0021] The beneficial effects of this invention are:

[0022] 1. This invention, by mounting lifeline posts on a tracked trolley, allows for adjustment of the lifeline post's position during trolley movement. This enables adjustments to the lifeline installation location based on operational needs, eliminating the need to install lifeline posts in every work area and effectively improving construction efficiency. Furthermore, the tracked trolley's track design increases the contact area between the trolley and the steel structure, improving stability and allowing the track and limiting blocks to act as clamping structures. Adjusting the limiting blocks to be flush against the bottom of the steel structure via a lifting mechanism clamps and secures the lifeline installation device. Simultaneously, adjusting the limiting blocks away from the steel structure releases the clamp, allowing the tracked trolley to move the lifeline post to the predetermined position. Thus, the high-altitude steel structure lifeline installation device of this invention can be remotely controlled to adjust the lifeline's installation position during operation, ensuring worker safety while effectively improving construction efficiency.

[0023] 2. This invention, by symmetrically arranging two lifting structures along the axial direction of the steel structure, can utilize the lifting structures, tracked trolley, and limiting blocks to form two symmetrical clamping structures. This avoids the tilting of the tracked trolley caused by unilateral clamping. Furthermore, the two clamping structures share the tracked trolley as one clamping end; in essence, the tracked clamping ends of the two clamping structures are interconnected, forming a single clamping system. In this system, the tracked trolley serves as one clamping end, and the two limiting blocks serve as the other. Compared to separate clamping structures, the interconnected clamping structure of this invention provides sufficient clamping force to ensure the stability between the tracked trolley and the steel structure.

[0024] 3. The high-altitude steel structure lifeline installation device of the present invention has a simple structure and is easy to operate. The lifeline can be laid out by manipulating the movement of the tracked trolley. At the same time, the tracked trolley can be locked on the steel structure by controlling the up and down movement of the limit block through the lifting structure. There is no need for operators to manually adjust the position of the lifeline poles, which effectively improves the safety of operation while improving construction efficiency.

[0030] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0032] Additionally, it should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0033] like Figures 1-2 As shown, the present invention provides a high-altitude steel structure lifeline installation device, comprising:

[0034] Steel structure 60;

[0035] A tracked trolley 10 is mounted on the upper surface of the steel structure 60 and can move along the steel structure 60. A lifeline upright 11 is mounted on the tracked trolley 10.

[0036] The lifting structure consists of two lifting structures symmetrically arranged along the axial direction of the steel structure 60. One end of each lifting structure is connected to the tracked trolley 10, and the other end is routed to the lower surface of the steel structure 60 and connected to the limit block 40.

[0037] The control system is used to control the movement of the tracked trolley 10 and the operation of the lifting structure;

[0038] When the lifting structure moves the limiting block 40 to be close to the bottom surface of the steel structure 60, the tracked trolley 10, the lifting structure, and the positioning block together form a clamping structure, which fixes the tracked trolley 10 to the steel structure 60. When the lifting structure moves the limiting block 40 away from the bottom surface of the steel structure 60, the clamping state is released, and the tracked trolley 10 can move freely relative to the steel structure 60 to lay the lifeline.

[0039] Specifically, the lifting structure includes a housing 20 with an internal cavity. The top of the housing 20 is connected to the side of the tracked trolley 10 via a horizontal fixing plate 30, allowing the lifting structure to be suspended from the side of the steel structure 60. A lifting assembly is installed inside the housing 20, and the output end of the lifting assembly is connected to a steering rod extending to the lower surface of the steel structure 60. The lifting assembly includes a screw 22, a slider 24 threaded onto and connected to the screw 22, and a driving component for driving the screw 22 to rotate. In this embodiment, the driving component is a motor 21, which is located at the top of the housing 20. A bearing seat 23 for enhancing the operational stability of the screw 22 is located at the bottom of the housing 20. One end of the screw 22 is connected to the output end of the motor 21, and the other end is connected to the bearing seat 23, so that the motor 21 drives the screw 22 to rotate, thereby causing the slider 24 threadedly connected to the screw 22 to move up and down.

[0040] Specifically, guide grooves 251 are provided on both sides of the inside of the housing 20, and a movable plate 25 is connected between the two guide grooves 251. The movable plate 25 is connected to the slider 24, so that when the screw 22 drives the slider 24 to move up and down, the slider 24 drives the movable plate 25 to move up and down along the two guide grooves 251.

[0041] Specifically, the bottom of the housing 20 is provided with a through groove running vertically through it; the steering rod includes a vertically connected vertical plate 261 and a horizontal plate 262. The vertical plate 261 passes through the through groove and is connected to the moving plate 25. The limiting block 40 is located at the end of the horizontal plate 262 away from the vertical plate 261. In this embodiment, the horizontal plate 262 extends to the middle of the bottom surface of the steel structure 60, so that the limiting block 40 is located below the middle of the bottom surface of the steel structure 60. By setting the steering rod, the up and down movement of the slider 24 can be used to control the up and down movement of the limiting block 40, thereby controlling the degree of contact between the limiting block 40 and the bottom surface of the steel structure 60 under the operation of the lifting structure. When the limiting block 40 is tightly attached to the bottom surface of the steel structure 60, the tracked trolley 10, the lifting structure, and the limiting block 40 together form a clamping structure.

[0042] Specifically, such as Figure 3As shown, a small box 50 is installed on the tracked trolley 10, and the control system is installed inside the small box 50. The control system includes a processor 51 and a power supply 52. ​​The power supply 52 provides power to the processor 51 and the lifting structure. Heat dissipation slots 53 are provided on both sides of the small box 50, and dustproof nets 54 are installed inside the heat dissipation slots 53 to ensure the heat dissipation requirements of the processor 51 and the power supply 52 while preventing dust from entering the interior of the small box 50.

[0043] Specifically, the lifeline steel wire rope 12 is connected to the top of the lifeline post.

[0044] Specifically, it also includes a remote control terminal, which is used to transmit control signals to the control system on the tracked trolley 10 to remotely control the movement of the tracked trolley 10 and the operation of the lifting structure.

[0045] Specifically, the tracked vehicle 10 is also equipped with a monitoring structure 13 for observing the number of safety belts located on the lifeline. In this embodiment, the monitoring structure 13 is a camera. The camera transmits the detected images to the processor 51. The processor 51 identifies the number of safety belts and sends the results to the remote control terminal to facilitate real-time monitoring of high-altitude workers and improve the safety of high-altitude operations.

[0046] Specifically, this invention utilizes the operation of a lifting structure to form a clamping structure with the tracked trolley 10, the lifting structure, and the limiting block 40, achieving a detachable connection between the lifeline pole 11 and the steel structure 60. Combined with the movement of the tracked trolley 10, the installation position of the lifeline pole 11 can be remotely controlled, thus automatically laying the lifeline pole 11 without the need for personnel, effectively improving construction efficiency while ensuring the safety of workers. The track section of the tracked trolley 10 has surface-to-surface contact with the upper surface of the steel structure 60, allowing the track section to adhere tightly to the steel structure 60 under the fastening force provided by the lifting structure. This ensures that the track section and the limiting block 40 are securely clamped onto the steel structure 60. The two track sections, in conjunction with the symmetrically arranged lifting structure and limiting block 40, ensure that the tracked trolley 10 is stably fixed to the steel structure 60, meeting the stability requirements of lifeline installation for the lifeline pole 11.

[0047] The working principle of the high-altitude steel structure lifeline installation device provided by the present invention will be explained below.

[0048] During operation, motor 21 drives screw 22 to rotate, causing slider 24 to move downwards. This causes the moving block connected to slider 24 to move downwards, which in turn causes the steering rod to move downwards. This moves the limiting block 40 fixed on the steering rod away from the bottom surface of steel structure 60, and then controls the tracked trolley 10 to move to the predetermined position for lifeline installation. Motor 21 then drives screw 22 to rotate, causing slider 24 to move upwards. This causes the moving block connected to slider 24 to move upwards, which in turn causes the steering rod to move upwards. This moves the limiting block 40 fixed on the steering rod to a position close to the bottom surface of steel structure 60, thus forming a clamping structure with the tracked trolley 10, the lifting structure, and the positioning block. The two symmetrical clamping structures stably fix the tracked trolley 10 to the steel structure 60, completing the installation of the lifeline post. When the installation position of the lifeline post needs to be adjusted, the lifting structure moves the limiting block 40 away from the bottom surface of steel structure 60 until the clamping state is released. This allows the tracked trolley 10 to move and adjust the position of the lifeline post 11.

[0049] 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.
