Description

Technical Field

[0001] This invention belongs to the field of automated masonry equipment technology, specifically relating to a frame system for group building construction. Background Technology

[0002] As the population ages and young people change their career choices, the labor shortage problem will become increasingly serious. For the construction of various structures such as blast furnaces, steel ladles and conventional buildings, it is essential to develop automated masonry equipment to replace manual masonry work.

[0003] Most existing automated bricklaying equipment is only suitable for fixed-point operations, and needs to be disassembled and reassembled when changing work areas. For group buildings such as steel ladle groups or blast furnace groups, the relocation of equipment to work areas consumes a lot of time, which greatly reduces the efficiency of construction operations in group building projects. Summary of the Invention

[0004] This invention provides a gantry system for the construction of group buildings, aiming to improve the efficiency of construction operations in group building projects.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is: to provide a gantry system for the construction of group buildings, comprising:

[0006] Two main rails are laid parallel to each other on the ground. The two main rails are located on both sides of each individual building area arranged in sequence and extend along the arrangement route of each individual building area.

[0007] The traveling gantry is set on two main rails and is used to travel along the main rails to the top of each individual building area;

[0008] The column is slidably connected to the middle of the traveling gantry in the vertical direction. The column has a supporting state where it is lowered to its bottom end to support the foundation of the structure or the ground, and also has a suspended state where its bottom end is higher than the top surface of the structure.

[0009] The masonry platform is slidably connected to the column in the vertical direction and has a self-driving mechanism connected to the column. The masonry platform rises and falls along the column under the drive of the self-driving mechanism.

[0010] The lifting component, located on the traveling gantry and with its output end connected to the column, is used to pull the column up and down relative to the traveling gantry.

[0011] In one possible implementation, the traveling gantry includes two main crossbeams spaced apart along the extension direction of the main rail, with a mounting bracket fixedly connected between the two main crossbeams. The mounting bracket is sleeved on the column and forms a sliding fit with the column.

[0012] In some embodiments, the mounting bracket is provided with multiple sets of rolling limit members, each set of rolling limit members is distributed vertically at intervals, and each set of rolling limit members rolls against the side wall of the column and forms a circumferential constraint on the column.

[0013] For example, each group of rolling limiting members consists of four members, and the four rolling limiting members in each group correspond to the four corner positions of the column. The rolling limiting member includes a fixed base, at least one first roller and at least one second roller. The fixed base is fixedly connected to the mounting bracket, and the first roller and the second roller are both connected to the fixed base. The first roller and the second roller roll on the edge positions of two adjacent side walls of the column near the same corner.

[0014] For example, a masonry platform includes:

[0015] The drive seat is slidably mounted on the column, and the drive seat is equipped with a self-driving mechanism.

[0016] The module connecting seat has a ring-shaped column set and fixed to the top of the drive seat. Slide plates are horizontally slidably connected to the two opposite side walls of the module connecting seat. The slide plates are used to fix and connect the bricklaying robot.

[0017] The manual operation platform is set around the drive seat and fixedly connected to the drive seat.

[0018] In one possible implementation, the self-driven mechanism includes:

[0019] Two drive motors are respectively mounted on two opposite side walls of the drive base, and each output end is fitted with a first gear;

[0020] Two first racks are fixedly connected to two opposite side walls of the column in the vertical direction, and are respectively meshed with two first gears.

[0021] In some embodiments, anti-fall brakes are provided on the two opposite side walls of the drive seat, and the brake gears of the two anti-fall brakes are respectively meshed with the two first racks.

[0022] For example, the boosting components include:

[0023] The winch is fixedly connected to one end of the traveling gantry frame, and the winch has two drums;

[0024] Two guide wheels are rotatably connected to the middle of the traveling gantry frame, and the two guide wheels are coaxially arranged and located on both sides of the column respectively;

[0025] Two traction ropes are wound around the drum of the winch. The two traction ropes pass over one of the guide wheels and extend vertically downwards. The extended ends of the two traction ropes are fixedly connected to the bottom two sides of the column.

[0026] For example, the bottom of the column is provided with a ball joint seat for supporting the foundation of the structure or the ground; multiple buffers are arrayed on the ball joint seat, and each buffer is aligned vertically with the bottom corner of the column.

[0027] In one possible implementation, the gantry system for mass building construction also includes:

[0028] The auxiliary rails are set parallel to the two main rails on the ground to the side;

[0029] The palletizing trolley has one end attached to the bottom of the traveling gantry frame near the auxiliary rail, and the other end rolled to the auxiliary rail. The palletizing trolley has a brick stacking area, and the position on the palletizing trolley located on the side of the brick stacking area is used to fix the destacking robot.

[0030] The scanning bracket is positioned above the brick stacking area. One end is fixedly connected to the top of the traveling gantry frame near the auxiliary rail, and the other end is fixedly supported on the stacking trolley. The scanning bracket is used to mount the brick stack scanning camera.

[0031] The beneficial effects of the gantry system for group building construction provided by this invention are as follows: Compared with the prior art, the gantry system for group building construction of this invention sets two main rails along the arrangement route of each individual building area in sequence, and connects the traveling gantry to the two main rails so that the traveling gantry can travel directly above any individual building area; after the traveling gantry reaches the target position, the lifting component drives the column to descend to a supported state where the bottom of the column is fixedly supported on the foundation of the structure or the ground. This allows the load on the masonry platform to be transferred to the foundation of the structure or the ground through the column during the masonry construction process, thereby avoiding the traveling gantry... The gantry can deform under overload, which also improves the stability of the columns and prevents the masonry platform from shaking and affecting construction operations. After the masonry of a structure in a single building area is completed, the column and the masonry platform connected to the column are simply lifted by the lifting component to a suspended state where the bottom of the column is higher than the top of the structure. Then, the traveling gantry moves along the main rail to a position directly above the next single building area and lowers the column back to the supporting state. The entire machine can be transferred without disassembly and reassembly, which can greatly reduce the time spent transferring the whole machine between different single building areas, thereby improving the efficiency of group building construction operations and shortening the project period.

[0041] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0042] It should be noted that when an element is referred to as being "set on" another element, it can be directly on or indirectly on the other element. It should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" or "several" means two or more, unless otherwise explicitly specified.

[0043] Please refer to the following: Figures 1 to 4 , Figure 6 The present invention will now describe the gantry system for group building construction. The gantry system for group building construction includes two main rails 10, a traveling gantry 20, columns 30, a masonry platform 40, and a lifting assembly 50. The two main rails 10 are laid parallel and spaced apart on the ground, located on both sides of each sequentially arranged individual building area and extending along the arrangement route of each individual building area. The traveling gantry 20 is mounted on the two main rails 10 and is used to travel along the main rails 10 to directly above each individual building area. The columns 30 are slidably connected vertically to the traveling gantry. In the middle of the gantry 20, the column 30 has a supported state where it is lowered to support the foundation of the structure or the ground, and also has a suspended state where its bottom is higher than the top surface of the structure. The masonry platform 40 is slidably connected to the column 30 in the vertical direction, and has a self-driving mechanism 400 connected to the column 30. The masonry platform 40 is raised and lowered along the column 30 under the drive of the self-driving mechanism 400. The lifting component 50 is located on the traveling gantry 20 and its output end is connected to the column 30. It is used to pull the column 30 to rise and fall relative to the traveling gantry 20.

[0044] It should be explained that, for group buildings such as steel ladles and blast furnaces, which are mostly arranged in a regular pattern such as a straight line or a circular line, the two main rails 10 are planned to extend along the path with the fewest curves based on the location of each individual building area required by the project. Since the construction process is carried out in a circular manner based on the masonry platform, the two main rails 10 should be placed on both sides of the individual building area to ensure that the column 30 can stand upright in the center of the individual building area.

[0045] It should be noted that, as Figure 3As shown, in this embodiment, both main rails 10 are I-shaped heavy rails. At least two load-bearing wheels 201 are respectively arranged at intervals on the bottom of both ends of the traveling gantry 20, which are rolled on the heavy rails. One of the load-bearing wheels 201 on each side is connected to the traveling motor to form a drive wheel. In order to avoid derailment, rail clamps 202 are provided at both ends of the traveling gantry 20 along its traveling direction to clamp the upper wing of the main rail 10. In addition, in order to improve the structural strength and dynamic load performance, each beam of the traveling gantry 20 adopts a box girder structure.

[0046] In this embodiment, for structures with a base (a bottom-closed substrate or foundation) such as a ladle, the bottom end of the column 30 is directly supported on the base of the structure when it is in the supported state. For structures without a base such as a blast furnace structure, the bottom end of the column 30 is directly supported on the center ground of the masonry area.

[0047] In this embodiment, the masonry platform 40 can be understood as serving as the installation base for both the masonry robot 90 and the manual work platform 43. This ensures that the masonry robot 90 and the manual work platform 43 rise synchronously with the masonry progress, meeting the requirements of human-machine collaborative operation. It should be understood that the masonry platform 40 is equipped with a self-drive mechanism 400 and performs self-drive lifting and lowering through the connection with the column 30. The lifting component 50 is used to drive the column 30 and the masonry platform 40 installed on the column 30 to rise and lower together.

[0048] The gantry system for group building construction provided in this embodiment, compared with the prior art, sets two main rails 10 along the arrangement route of each individual building area, and connects the traveling gantry 20 to the two main rails 10 so that the traveling gantry 20 can travel directly above any individual building area; after the traveling gantry 20 reaches the target position, the lifting component 50 drives the column 30 to descend to a supported state where the bottom of the column 30 is fixedly supported on the foundation of the structure or the ground. This allows the load on the masonry platform 40 to be transferred to the foundation of the structure or the ground through the column 30 during the masonry construction process, thereby avoiding overload deformation of the traveling gantry 20, and also... This improves the stability of the column 30 and prevents the masonry platform 40 from swaying and affecting construction operations. After the masonry of a structure in a single building area is completed, the column 30 and the masonry platform 40 connected to the column 30 are simply lifted by the lifting component 50 to a suspended state where the bottom of the column 30 is higher than the top surface of the structure. Then, the traveling gantry 20 travels along the main rail 10 to a position directly above the next single building area and lowers the column 30 back to the support state. The entire machine can be transferred without disassembly and reassembly, which can greatly reduce the time spent transferring the machine between different single building areas, thereby improving the efficiency of group building construction operations and shortening the project period.

[0049] In some embodiments, see Figure 2 and Figure 4 The traveling gantry 20 includes two main crossbeams 21 spaced apart along the extension direction of the main rail 10. A mounting bracket 22 is fixedly connected between the two main crossbeams 21. The mounting bracket 22 is sleeved on the column 30 and forms a sliding fit with the column 30.

[0050] Based on the connection requirements of the two main crossbeams 21, both sides of the traveling gantry 20 adopt an isosceles trapezoidal structure. Specifically, this isosceles trapezoidal structure is formed by an end beam 23 equipped with rollers, two support beams 24 connected to both ends of the end beam 23, and a crossbeam 25 connected to the top of the two support beams 24. The ends of the two main crossbeams 21 are fixedly connected to the crossbeam 25. The end beams 23, support beams 24, crossbeams 25, and main crossbeams 21 are all box-type beam structures. Preferably, the main crossbeams 21 are variable cross-section box beams with cross-sectional dimensions gradually increasing from both ends to the middle, thereby improving the load-bearing capacity of the main crossbeams 21 and preventing the main crossbeams 21 from bending downwards in the middle when the column 30 is suspended. Furthermore, by setting up an installation bracket 22 to form all-around contact with the column 30, the connection stability of the column 30 can be improved, preventing the column 30 from tilting under stress.

[0051] Specifically, in this embodiment, the mounting bracket 22 is provided with multiple sets of rolling limiting members 221. Each set of rolling limiting members 221 is distributed vertically at intervals, and each set of rolling limiting members 221 rolls against the side wall of the column 30 and forms a circumferential constraint on the column 30.

[0052] The column 30 can adopt a rectangular or square column structure. Each set of rolling limiters 221 on the corresponding mounting bracket 22 can achieve rolling contact with the four side walls of the column 30, thereby forming a circumferential constraint on the column 30. At the same time, the vertically spaced distribution of each set of rolling limiters 221 can increase the contact length between the mounting bracket 22 and the column 30, thereby increasing the constraint force on the column 30 and ensuring the connection stability of the column 30. On this basis, the rolling method of each set of rolling limiters 221 on the side walls of the column 30 replaces the conventional sliding friction, which can not only reduce the lifting resistance of the column 30, but also eliminate the need for a fitting gap compared to the sliding fit, thereby improving the connection stability of the column 30 on the mounting bracket 22 and preventing the column 30 from shaking.

[0053] It should be noted that the number of each group of rolling limiters 221 is four, and the four rolling limiters 221 in each group correspond to the four corner positions of the column 30; the structure of the rolling limiter 221 is as follows: Figure 5As shown, it includes a fixed base 2211, at least one first roller 2212 and at least one second roller 2213; wherein, the fixed base 2211 is fixedly connected to the mounting bracket 22, the first roller 2212 and the second roller 2213 are both connected to the fixed base 2211, and the first roller 2212 and the second roller 2213 respectively roll on the edge positions of two adjacent side walls of the column 30 near the same corner.

[0054] For the column 30 with a square or rectangular column structure, the first roller 2212 and the second roller 2213 on each rolling limit member 221 are perpendicular to each other in axis, so that the first roller 2212 and the second roller 2213 can roll on the two side wall edges of the column 30 near the same corner. Thus, by using the four rolling limit members 221 in each group to limit the four corners of the column 30 in both directions, the column 30 is fully constrained in the circumference. On this basis, multiple first rollers 2212 and multiple second rollers 2213 can be arranged vertically and vertically on each rolling limit member 221. With the multiple groups of rolling limit members 221 distributed vertically and vertically, not only can sufficient rolling contact points be ensured on the side wall of the column 30, but the contact length with the side wall of the column 30 is also increased, thereby improving the connection reliability and movement stability of the column 30.

[0055] As a specific structure of the aforementioned masonry platform 40, please refer to Figure 1 and Figure 6 The masonry platform 40 includes a drive base 41, a module connecting base 42, and a manual operation platform 43. The drive base 41 is slidably mounted on the column 30 and is equipped with a self-driving mechanism 400. The module connecting base 42 is arranged around the column 30 and fixed to the top of the drive base 41. Slide plates 421 are horizontally slidably connected to the two opposite side walls of the module connecting base 42. The slide plates 421 are used to fix the masonry robot 90. The manual operation platform 43 is arranged around the drive base 41 and fixedly connected to the drive base 41.

[0056] For details, see Figure 7The drive base 41 has two horizontal slide rails 422 spaced vertically on its two opposite sidewalls for slidingly connecting the slide plate 421. A second rack 423 is horizontally arranged between the two horizontal slide rails 422. A rotary drive component 44 is fixedly connected to the slide plate 421. A second gear 441 is sleeved on the output end of the rotary drive component 44, and the second gear 441 meshes with the second rack 423. Specifically, the rotary drive component 44 can be a servo motor or a stepper motor. The rotary drive component 44 drives the second gear 441 to rotate, thereby causing the second gear 441 to roll along the second rack 423. This enables the slide plate 421, which is fixedly connected to the rotary drive component 44, to move along the horizontal slide rails 422. The structure is simple and the movement is smooth, which facilitates precise positioning of the bricklaying robot 90 in space, thus ensuring the accuracy of the bricklaying robot 90's movements.

[0057] The drive seat 41 connected to the column 30 can drive the module connecting seat 42 to rise and fall synchronously, thereby enabling the two masonry robots 90 installed on the module connecting seat 42 to adjust their real-time height according to the construction progress. At the same time, the horizontal sliding of the sliding plate 421 on the module connecting seat 42 can increase the working radius of the masonry robot 90. The manual work platform 43 connected to the drive seat 41 is used to carry the on-site workers, realizing human-machine collaborative operation. The load of the masonry robot 90 can be directly applied to the column 30 through the module connecting seat 42. Compared with setting the masonry robot 90 on the manual work platform 43, it can avoid the impact of the shaking of the manual work platform 43 on the movement accuracy of the masonry robot 90, thus helping to improve the quality of masonry construction. Moreover, it can reduce the stability requirements of the manual work platform 43, save the time of additional support for the manual work platform 43, and thus improve the overall transfer efficiency.

[0058] Please see Figure 6 and Figure 8 The self-driving mechanism 400 includes two drive motors 401 and two first racks 403; wherein, the two drive motors 401 are respectively disposed on two opposite side walls of the drive base 41, and each output end is fitted with a first gear 402; the two first racks 403 are respectively fixedly connected to two opposite side walls of the column 30 in the vertical direction, and respectively mesh with the two first gears 402.

[0059] The drive motor 401 drives the first gear 402 to rotate, thereby causing the first gear 402 to roll up and down along the first rack 403 to achieve the lifting and lowering of the drive seat 41. The structure is simple and reliable. On this basis, since a set of drive motors 401 and first racks 403 are provided on both sides of the column 30, the force on the drive seat 41 can be balanced, thereby improving the lifting and lowering stability of the drive seat 41.

[0060] To improve the safety of masonry construction operations, combined with Figure 6 and Figure 8 It is understood that anti-fall brakes 411 are provided on both opposite side walls of the drive seat 41, and the brake gears of the two anti-fall brakes 411 are respectively meshed with the two first racks 403. The anti-fall brakes 411 can quickly brake and lock falling objects within a limited distance. The anti-fall brakes 411 used here are elevator anti-fall devices, and brake gears are sleeved on their shafts. The brake gears are meshed with the first racks 403, and can brake the shaft in an emergency when the self-drive mechanism 400 fails, thereby locking the first racks 403 and preventing the drive seat 41 from falling. The anti-fall braking is achieved by means of the first racks 403 of the self-drive mechanism 400, which can improve the structural compactness.

[0061] Optionally, please see Figure 1 In some embodiments, the lifting assembly 50 includes a winch 51, two guide wheels 52, and two wire ropes; wherein, the winch 51 is fixedly connected to one end of the traveling gantry 20, and the winch 51 has two drums; the two guide wheels 52 are respectively rotatably connected to the middle of the traveling gantry 20, and the two guide wheels 52 are coaxially arranged and located on both sides of the column 30; the two traction ropes 53 are respectively wound on the drums of the winch 51, and the two traction ropes 53 respectively pass around one of the guide wheels 52 and extend vertically downward, and the extended ends of the two traction ropes 53 are respectively fixedly connected to the bottom two sides of the column 30.

[0062] The winch 51 can be set at the end of the main crossbeam 21 of the traveling gantry 20, thereby reducing the load on the middle of the main crossbeam 21. The guide wheel 52 makes the wire rope bend downward near the column 30, so that the wire rope can be connected to the bottom of the column 30 at a vertical or near-vertical angle, thereby reducing the force on the column 30 in the non-vertical direction and improving the stability of the column 30 in the lifting and lowering movement under the traction of the wire rope.

[0063] Based on this, since it is difficult for a single wire rope to ensure the overall force balance of the column 30, two drums are used to connect two wire ropes to pull the column 30. The two wire ropes can be used to pull the bottom two sides of the column 30 respectively. Since the two drums are driven by the same winch 51, the pulling force of the two wire ropes can be kept consistent, thus ensuring the force balance of the column 30. Moreover, the two wire ropes have strong load-bearing capacity, so it can also avoid the accident of the column 30 falling due to the wire rope breaking.

[0064] It should be noted that, as Figure 1 As shown, the bottom end of the column 30 is provided with a ball joint seat 31 for supporting the foundation of the structure or the ground; multiple buffers 32 are arranged in an array on the ball joint seat 31, and each buffer 32 is aligned vertically with the bottom corner of the column 30.

[0065] Since the foundation or ground of a structure may not be level, such as the lining of a steel ladle which is usually spherical, the ball joint seat 31 is used to support the foundation or ground of the structure. The ball joint seat 31 can be used to provide stable support by adapting to the flatness of the foundation or ground. At the same time, it can also avoid the column 30 being subjected to non-vertical forces due to the uneven support surface, thereby improving the stability of the support state of the column 30.

[0066] The buffer 32 can be a rubber column. When the two steel wire ropes drive the column 30 to move upward, in order to avoid the ball joint seat 31 from rigidly colliding with the drive seat 41 or the main crossbeam 21 of the traveling gantry 20, the buffer 32 is set here to buffer the collision force. At the same time, the buffer 32 can also be used to limit the movement of the column 30 by abutting the drive seat 41 or the traveling gantry 20, thereby preventing the column 30 from sliding too far upward, thus improving the safety of the lifting and lowering movement of the column 30.

[0067] As a variation of the aforementioned gantry system for group building construction, please refer to Figure 1 and Figure 2 The rack system also includes auxiliary rails 60, a palletizing platform, and a scanning bracket 80. The auxiliary rails 60 are arranged parallel to the ground on the sides of the two main rails 10. One end of the palletizing trolley 70 is fixed to the bottom of the traveling gantry 20 near the auxiliary rails 60, and the other end is rolled to the auxiliary rails 60. The palletizing trolley 70 has a brick stacking area 701, and a destacking robot 702 is fixed to the side of the brick stacking area 701 on the palletizing trolley 70. The scanning bracket 80 spans above the brick stacking area 701, with one end fixedly connected to the top of the traveling gantry 20 near the auxiliary rails 60, and the other end fixedly supported on the palletizing trolley 70. A brick stack scanning camera 801 is mounted on the scanning bracket 80.

[0068] It should be explained that for commonly used automatic bricklaying equipment, a platform for stacking bricks is usually set on the frame. This is not a problem for a fixed frame for stationary operations. However, for mobile gantry cranes 20, the load of the brick stacks and the destabilizing robot 702 can cause the mobile gantry crane 20 to become unbalanced, especially when the column 30 is suspended and the whole machine is being moved, which can easily lead to a tilting accident. Therefore, in this embodiment, a palletizing platform is set on the side of the traveling gantry 20 using the auxiliary rail 60, and the depalletizing robot 702 is fixed on the palletizing platform. On the one hand, the supporting effect of the auxiliary rail 60 can avoid the traveling gantry 20 from bearing the load of the brick stack and the depalletizing robot 702, thereby ensuring the stability of the traveling gantry support. On the other hand, the palletizing platform can move synchronously with the driving force of the traveling gantry 20, thereby ensuring the accuracy of the depalletizing robot 702 transferring bricks to the conveyor line on the traveling gantry 20. On this basis, a scanning bracket 80 for mounting a brick stack scanning camera 801 is set directly above the brick stack stacking area 701, which facilitates the brick stack scanning camera 801 to directly scan the brick stack facing downwards, thereby improving the accuracy of the scanning position data. At the same time, the connection between the scanning bracket 80 and the top of the traveling gantry 20 can avoid the legs of the scanning bracket 80 being too long and affecting its connection stability, thereby ensuring the stability of the brick stack scanning camera 801 and improving the accuracy of the brick stack scanning data.

[0069] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
