Description

Technical Field

[0001] This invention relates to the field of construction equipment, and more particularly to a rail-mounted moving platform for tower cranes. Background Technology

[0002] At construction sites, auxiliary equipment such as searchlights, anemometers, and cameras are typically installed at the base of tower cranes to improve their performance due to their height. However, if these devices malfunction, replacement and repair are complex; safety personnel must climb the tower crane to inspect their condition, and the number of climbs per day is limited, resulting in significant labor intensity.

[0003] Therefore, three difficulties are encountered in actual production: First, the maintenance and monitoring points are located at high altitudes, which involves high-altitude operations, posing significant risks and requiring high levels of professional skills and physical strength from personnel; second, the internal space of the standard sections of tower cranes is cramped, hindering the work of personnel; and third, personnel need to use various auxiliary tools, and the labor intensity caused by climbing loads is considerable. Therefore, it is necessary to provide corresponding devices capable of supporting the aforementioned auxiliary equipment.

[0004] In the existing technology, there is a lack of a mobile load-bearing platform specifically adapted to tower cranes. After the auxiliary equipment is installed, it is difficult to adjust its position. During maintenance, personnel need to climb at heights, resulting in high operational risks and low efficiency. Some simple mobile platforms cannot stably load auxiliary equipment and are inconvenient to move, failing to meet the operational needs of different heights and positions. They are unable to solve the above-mentioned construction pain points. There is an urgent need for a sliding rail mobile platform that is structurally stable, flexible, capable of loading auxiliary equipment, and convenient for personnel to operate. Summary of the Invention

[0005] The main objective of this invention is to provide a rail-mounted mobile platform for tower cranes, which solves the technical problems that simple mobile platforms cannot stably load auxiliary equipment, are inconvenient to move, and cannot adapt to the operational needs of different heights and positions.

[0006] To achieve the above objectives, the present invention provides a slide rail moving platform for a tower crane, comprising: a main frame;

[0008] The positioning guide rail is located on the side wall of the main frame and extends along the axial direction of the main frame;

[0009] The positioning hook is located on the inner side of the main frame and is used to connect with the standard section beam of the tower crane;

[0010] The mobile platform, mounted on the main frame, has gears that cooperate with the rack and pinion guide rail, positioning wheels that cooperate with the positioning guide rail, and a mounting part for installing auxiliary equipment.

[0011] According to the embodiments of this application, the teeth at both ends of the rack are half-section teeth, and the half-section teeth of two adjacent rack sections can be spliced ​​together to form teeth.

[0012] According to an embodiment of this application, the positioning hook includes multiple pairs of upper and lower positioning hooks used in conjunction; in any pair of upper and lower positioning hooks, the hook tip of the upper positioning hook and the hook tip of the lower positioning hook face each other; the distance between the upper and lower positioning hooks corresponds to the height of the standard section.

[0013] According to an embodiment of this application, the main frame is provided with an upper mounting groove and a lower mounting groove arranged along its own axial direction; the upper positioning hook can be moved and positioned in the upper mounting groove and fixed by bolts; the lower positioning hook can be moved and positioned in the lower mounting groove and fixed by bolts.

[0014] According to the embodiments of this application, there are two positioning guide rails; the two positioning guide rails are located on both sides of the rack guide rail; the positioning guide rails are round steel and are connected to the main frame through a steel structure; there are two positioning wheels, which are in contact with the corresponding positioning guide rails respectively.

[0015] According to an embodiment of this application, the contact direction between the two positioning wheels and the corresponding positioning guide rail is perpendicular.

[0016] According to an embodiment of this application, the mounting part includes a socket provided in the mobile platform and a clamping body that mates with the socket, the clamping body having a shaft hole that mates with the auxiliary equipment.

[0017] According to an embodiment of this application, the outer peripheral surface of the clamp body has a snap fastener.

[0019] According to an embodiment of this application, the auxiliary device is a suspended basket, which is fixed to the shaft hole by mounting screws.

[0020] The aforementioned sliding rail moving platform for tower cranes is precisely connected to the main frame and the standard section crossbeam of the tower crane, ensuring a stable structure and providing reliable support for platform movement and auxiliary equipment installation. The rack and pinion guide rail, in conjunction with the platform's gears, allows for flexible movement along the main frame's axial direction, eliminating the need for personnel to climb and enabling adjustments to auxiliary equipment positions and maintenance work, thus reducing the risks of working at heights.

[0047] An embodiment of this application provides a slide rail moving platform 500 for a tower crane, see [link to relevant documentation]. Figure 1 , Figure 2 and Figure 3 The system includes: a main frame 100, a rack and pinion guide rail 200, a positioning guide rail 300, a positioning hook 400, and a moving platform 500. The rack and pinion guide rail 200 is located on the outer side of the main frame 100 and extends axially along the main frame 100. The rack and pinion guide rail 200 includes multiple racks 210 connected end-to-end in sequence. The positioning guide rail 300 is located on the side wall of the main frame 100 and extends axially along the main frame 100. The positioning hook 400 is located on the inner side of the main frame 100 and is used to connect with the standard section 700 crossbeam of the tower crane. The moving platform 500 is mounted on the main frame 100 and has a gear 510 that meshes with the rack and pinion guide rail 200, a positioning wheel 520 that meshes with the positioning guide rail 300, and a mounting part 530 for mounting auxiliary equipment.

[0048] The main frame 100 is made of high-strength steel structure 310 welded together. It has a frame structure with sufficient load-bearing capacity and stability, and is suitable for the load requirements of tower crane high-altitude operation. Its size is compatible with the standard section 700 of the tower crane, which facilitates the connection between the positioning hook 400 and the crossbeam of the standard section 700.

[0049] The rack and pinion guide rail 200 is fixedly installed on the outer side of the main frame 100, extending axially along the main frame 100. It is composed of multiple racks 210 connected end to end, and can be flexibly spliced ​​according to the height of the tower crane to adapt to different height operation requirements. The rack and pinion guide rail 200 meshes with the gear 510 on the moving platform 500. The rotation of the gear 510 drives the moving platform 500 to move up and down along the rack and pinion guide rail 200, realizing the adjustment of auxiliary equipment position and personnel maintenance operations without the need for personnel to climb the tower crane, reducing operational risks.

[0050] The positioning guide rail 300 is fixed to the side wall of the main frame 100 and extends parallel to the rack 210 and guide rail 200. It is used to cooperate with the positioning wheel 520 to limit the movement direction of the mobile platform 500, prevent the mobile platform 500 from deviating or shaking when it moves, and improve the stability and safety of the movement of the mobile platform 500.

[0051] The positioning hook 400 is installed on the inner side of the main frame 100 and is used to engage with the crossbeam of the standard section 700 of the tower crane to fix the main frame 100 to the tower crane, ensuring that the entire sliding rail moving platform 500 is firmly installed and does not shift. The moving platform 500, as a carrier for the installation of auxiliary equipment and personnel operations, is installed on the main frame 100. Through the cooperation of the gear 510 and the rack 210 guide rail 200, and the positioning wheel 520 and the positioning guide rail 300, it can move flexibly along the main frame 100. Its mounting part 530 is used to fix various auxiliary equipment, and can also carry operators and tools, solving the problem of limited internal space and inconvenience for personnel operations in the standard section 700.

[0052] The aforementioned sliding rail moving platform 500 for tower cranes is precisely connected to the crossbeam of the standard section 700 of the tower crane via the main frame 100, providing a stable structure and reliable support for the movement of the moving platform 500 and the installation of auxiliary equipment. The rack 210 and guide rail 200 cooperate with the gear 510 of the moving platform 500 to enable the moving platform 500 to move flexibly along the axial direction of the main frame 100, allowing for adjustment of auxiliary equipment positions and maintenance work without the need for personnel to climb, thus reducing the risks of working at heights. The positioning guide rail 300 and positioning wheel 520 cooperate to ensure that the moving platform 500 moves smoothly and without deviation, improving operational safety. The installation unit 530 can flexibly install various auxiliary equipment to adapt to different construction needs. Multiple racks 210 are spliced ​​end to end to form rack 210 guide rail 200, which can be adapted to tower cranes of different heights; the positioning hook 400 can be flexibly adjusted to adapt to standard sections 700 of different specifications; the auxiliary equipment is easy to install and disassemble, further improving work efficiency and completely solving the problems of inconvenient installation and maintenance of auxiliary equipment, high labor intensity of personnel, and high operation risk in existing construction.

[0053] According to the embodiments of this application, see Figure 1The teeth at both ends of the rack 210 are half-section teeth, and the half-section teeth of two adjacent rack sections 210 can be joined together to form teeth.

[0054] Each rack 210 has half-pitch teeth at both ends. When multiple racks 210 are spliced ​​end to end, the half-pitch teeth of adjacent racks 210 can precisely mesh to form complete teeth, ensuring the continuity and flatness of the rack 210 guide rail 200 and preventing missing or misaligned teeth at the splice point. This ensures smooth meshing between the gear 510 and the rack 210 guide rail 200, and stable movement of the moving platform 500 without jamming. At the same time, this splicing method facilitates the transportation, installation, and disassembly of the racks 210, and the number of racks 210 can be flexibly adjusted according to the height of the tower crane, improving the versatility and adaptability of the device. Furthermore, the gear 510 and rack 210 connection pair can meet the requirements of long-stroke motion.

[0055] According to the embodiments of this application, see Figure 1 , Figure 2 , Figure 3 and Figure 4 The positioning hook 400 includes multiple pairs of mating upper positioning hooks 410 and lower positioning hooks 420. In any pair of upper positioning hooks 410 and lower positioning hooks 420, the hook tips of the upper positioning hook 410 and the hook tips of the lower positioning hook 420 face each other. The distance between the upper positioning hooks 410 and lower positioning hooks 420 corresponds to the height of the standard section 700.

[0056] The positioning hook 400 employs a structure with multiple pairs of upper positioning hooks 410 and lower positioning hooks 420. Each pair of positioning hooks 400 engages with the upper and lower crossbeams of the standard section 700 of the tower crane. The hook tip of the upper positioning hook 410 points downwards, while the hook tip of the lower positioning hook 420 points upwards. This opposing arrangement forms a bidirectional engagement with the crossbeams of the standard section 700, ensuring a secure connection between the main frame 100 and the standard section 700, preventing vertical displacement. The distance between the upper positioning hooks 410 and the lower positioning hooks 420 precisely corresponds to the height of the standard section 700, allowing for direct engagement with the crossbeams without additional adjustment, simplifying installation. The multiple pairs of positioning hooks 400 are evenly distributed across the main frame 100, ensuring uniform stress distribution and further enhancing connection stability, thus meeting the load requirements of high-altitude operations.

[0057] According to the embodiments of this application, see Figure 1 , Figure 2 and Figure 3 The main frame 100 is provided with an upper mounting groove 110 and a lower mounting groove 120 arranged along its own axial direction. The upper positioning hook 410 can be moved and positioned within the upper mounting groove 110 and fixed with bolts. The lower positioning hook 420 can be moved and positioned within the lower mounting groove 120 and fixed with bolts.

[0058] Both the upper mounting slot 110 and the lower mounting slot 120 are axially formed along the main frame 100. The upper positioning hook 410 is slidably installed in the upper mounting slot 110, and the lower positioning hook 420 is slidably installed in the lower mounting slot 120. Both can move flexibly along the mounting slots to adjust the spacing, thereby adapting to tower crane standard sections 700 of different heights and specifications, thus ensuring the versatility of the lifting device. After the positioning hook 400 is moved to the target position, it is fixed to the main frame 100 by bolts passing through the connection holes between the mounting slot and the positioning hook 400. The fixation is firm and reliable, capable of withstanding the load of the moving platform 500 and auxiliary equipment, preventing the moving platform 500 from shaking due to displacement of the positioning hook 400, and ensuring operational safety.

[0059] According to the embodiments of this application, see Figure 5 and Figure 6 There are two positioning guide rails 300. The two positioning guide rails 300 are located on both sides of the rack 210 guide rail 200. The positioning guide rails 300 are made of round steel and are connected to the main frame 100 via a steel structure 310. There are two positioning wheels 520, each in contact with its corresponding positioning guide rail 300.

[0060] Two positioning guide rails 300 are symmetrically arranged on both sides of the rack 210 guide rail 200. Made of high-strength round steel, they are fixed to the main frame 100 by welding or bolting, resulting in a stable structure that is not easily deformed. The smooth surface of the round steel reduces friction when the positioning wheels 520 move, allowing the moving platform 500 to move more smoothly. The two positioning wheels 520 are respectively mounted on the moving platform 500, engaging with their corresponding positioning guide rails 300 to guide and limit the moving platform 500 from both sides, preventing it from shifting to either side and ensuring that the moving platform 500 always moves along the axial direction of the main frame 100. This improves the stability and safety of the moving platform 500's movement, while also distributing the load on the moving platform 500, reducing the stress on the gear 510 and the rack 210 guide rail 200, and extending the service life of the device.

[0061] According to the embodiments of this application, see Figure 5 and Figure 6 The two positioning wheels 520 are perpendicular to the contact direction of the corresponding positioning guide rail 300.

[0062] The two positioning wheels 520 are installed perpendicular to each other and are also perpendicular to the contact direction with the corresponding positioning guide rail 300. One positioning wheel 520 is used to limit the left and right offset of the mobile platform 500 in the width direction, and the other positioning wheel 520 is used to limit the swaying of the mobile platform 500 in the length direction, forming a two-way limit, which further improves the stability and accuracy of the movement of the mobile platform 500, avoids the mobile platform 500 from tilting or swaying during movement, ensures the safety of operators and auxiliary equipment, and meets the stringent requirements of high-altitude operations.

[0063] According to the embodiments of this application, see Figure 7 , Figure 8 and Figure 9 The mounting part 530 includes a socket 531 disposed on the mobile platform 500 and a clamping body 532 that mates with the socket 531. The clamping body 532 has a shaft hole that mates with the auxiliary equipment.

[0064] A socket 531 is formed on the surface of the moving platform 500, and its size is adapted to the clamp body 532. The clamp body 532 can be detachably installed in the socket 531, facilitating the replacement of clamp bodies 532 of different specifications to adapt to different types of auxiliary equipment. A shaft hole is formed in the center of the clamp body 532, which is used to mate with the mounting part 530 of the auxiliary equipment (such as the mounting screw 610). The auxiliary equipment is fixed to the clamp body 532 by tightening nuts or other means, ensuring firm installation and convenient disassembly, allowing for quick installation and replacement of auxiliary equipment and improving work efficiency. At the same time, the clamp body 532 can position the auxiliary equipment, preventing it from shifting or shaking during the movement of the moving platform 500.

[0065] According to the embodiments of this application, see Figure 7 , Figure 8 and Figure 9 The outer peripheral surface of the clamp body 532 has a buckle 533.

[0066] The clamp body 532 has a snap-fit ​​533 on its outer peripheral surface. When the clamp body 532 is installed in the socket 531, the snap-fit ​​533 can engage with the inner wall of the socket 531, achieving quick positioning and initial fixation of the clamp body 532. This prevents the clamp body 532 from rotating or shifting within the socket 531, further improving the installation stability of the auxiliary equipment. Simultaneously, the snap-fit ​​533 structure facilitates the quick installation and disassembly of the clamp body 532 without the need for complex tools, reducing operational difficulty and improving work efficiency.

[0067] Because the clamping body 532 achieves quick clamping and stable force by engaging with the socket 531 through the buckle 533, it realizes the unified interface for connecting different modules (i.e., auxiliary equipment) with the transport platform.

[0068] Moreover, the connection between the auxiliary equipment and the fixture 532 is simple and reliable, and this connection method can accommodate different functional devices mounted on the carrier platform, with strong expandability.

[0069] According to the embodiments of this application, see Figure 10 and Figure 11 The auxiliary device is a camera device, which includes a mounting screw 610, a robotic arm 620, and a camera 630. The mounting screw 610 is connected to the robotic arm 620 and fixed in the shaft hole. The robotic arm 620 has multiple degrees of freedom, and the camera 630 is mounted at the end of the robotic arm 620.

[0070] When the auxiliary equipment is a camera, the mounting screw 610 is fixedly connected to one end of the robotic arm 620. The mounting screw 610 passes through the shaft hole of the clamping body 532 and is tightened with a nut to secure it, thus connecting the camera to the mobile platform 500. The robotic arm 620 has multiple degrees of freedom, allowing for flexible adjustment of its angle and position, driving the camera 630 to rotate and extend, expanding the monitoring range and adapting to the monitoring needs of different locations on the construction site. The camera 630 is installed at the end of the robotic arm 620, enabling precise capture of images from the construction site. It eliminates the need for personnel to climb and adjust the position of the camera 630, reducing operational risks and improving monitoring convenience.

[0071] For example, the robotic arm 620 includes a rotary assembly 621, a first rotary joint 622, and a second rotary joint 623. The rotary assembly 621 is responsible for horizontal rotation; while the first rotary joint 622 and the second rotary joint 623 are responsible for vertical rotation. Combined with the height variation of the moving platform 500, it has a total of four degrees of freedom. All components of the robotic arm 620 are made of high-molecular polymers such as resin, resulting in low cost and light weight, which meets the usage requirements.

[0072] According to the embodiments of this application, see Figure 12 and Figure 13 The auxiliary equipment is a suspended basket 640, which is fixed to the shaft hole by a mounting screw 610.

[0073] When the auxiliary equipment is a suspended platform 640, a mounting screw 610 is installed on the top of the suspended platform 640. The mounting screw 610 passes through the shaft hole of the clamping body 532 and is tightened with a nut to securely install the suspended platform 640 onto the mobile platform 500. Workers can enter the suspended platform 640 and move along the main frame 100 with the mobile platform 500 to carry out tower crane maintenance and auxiliary equipment upkeep, eliminating the need to climb the tower crane and reducing the risks of working at heights. Simultaneously, the suspended platform 640 can carry work tools, reducing the labor intensity of personnel and solving the problem of limited internal space and inconvenient operation in the standard section 700, thereby improving work efficiency and safety.
