Description

Technical Field

[0001] This invention belongs to the field of steel structure space frame deformation detection technology, specifically involving a trolley for detecting buckling deformation of steel structure space frame members. Background Technology

[0002] Steel space frame is a type of spatial structure composed of multiple members connected by nodes in a certain grid pattern. It has the advantages of low spatial stress, light weight, high rigidity and good seismic performance, and is widely used in large-space buildings such as stadiums, theaters, exhibition halls, and waiting halls.

[0003] Since steel space frames are mainly used as roofs for large-space buildings, which often involve large gatherings of people, the safety and stability of these structures are of paramount importance. Bending deformation of the members is a common problem in practical applications. This deformation not only reduces the overall stiffness of the steel space frame but can also lead to its collapse in severe cases. Therefore, regular bending deformation testing of the steel space frame members is crucial for its safe use.

[0004] Currently, existing technologies mainly use manual methods such as pulling a plumb line and using a plumb bob to detect whether the steel structure space frame members are bent or deformed. Since there are a large number of steel structure space frame members, this method is inefficient. At the same time, the detection process is easily affected by environmental factors, human factors and other factors, resulting in incomplete and inaccurate detection results. In addition, since steel structure space frame members are generally erected at a high position, manual detection poses significant safety hazards.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0006] The purpose of this invention is to provide a trolley for detecting buckling deformation of steel structure space frame members, which can improve the efficiency, accuracy and safety of bending detection of steel structure space frame members.

[0007] To achieve the above objectives, a specific embodiment of the present invention provides the following technical solution:

[0008] The steel structure space frame member buckling deformation detection trolley includes: detection frame, tilt sensor, multiple sets of multi-directional moving wheels, a pair of magnetic adsorption limiting components, and spray marking components.

[0009] An inclination sensor is fixedly mounted on the lower part of the testing frame. The inclination sensor detects the inclination data of the steel structure frame members, and the degree of bending deformation of the frame members is judged by the changes in the inclination data.

[0010] The specific determination method is as follows: when the walking angle detected by the tilt sensor shows a large-small-large or small-large-small change, it is determined that the steel structure space frame member has bending deformation. Furthermore, the greater the angle change detected by the tilt sensor, the more severe the bending deformation of the steel structure space frame member is determined. When the angle detected by the tilt sensor does not change or the angle change shows a sawtooth-like small fluctuation, and the angle change amplitude is within the error range, it is determined that the steel structure space frame member does not have bending deformation.

[0011] Multiple sets of the multi-directional moving wheel sets are fixedly mounted on the lower part of the inspection vehicle frame. Each multi-directional moving wheel set includes an assembly frame, which is hinged to the bottom of the inspection vehicle frame. A drive motor is fixedly mounted inside the assembly frame. An axle is rotatably connected to the side of the assembly frame away from the drive motor. The axle is drively connected to the output shaft of the drive motor. A wheel frame is fixedly mounted on the outer side of the axle. Multiple sets of evenly distributed friction rollers are rotatably connected to the outer side of the wheel frame.

[0012] A pair of magnetic adsorption limiting components are fixedly assembled at the bottom of the testing vehicle frame. The magnetic adsorption limiting components include a shrink limiting cylinder, which is fixedly assembled inside the testing vehicle frame. A connecting rod is slidably assembled inside the shrink limiting cylinder. An adsorption plate is hinged to one end of the connecting rod outside the shrink limiting cylinder. A flexible adsorption pad is fixedly connected to the side of the adsorption plate away from the shrink limiting cylinder. Multiple evenly distributed magnetic adsorption beads are embedded in the flexible adsorption pad.

[0013] The spray marking assembly is fixedly mounted on the outside of the tilt sensor, and the spray marking assembly is used to spray marking on the rod.

[0014] In one or more embodiments of the present invention, a fixing frame is hinged to the side of the assembly frame close to the test vehicle frame. The fixing frame serves to limit the assembly of the assembly frame. Simultaneously, the swinging motion of the fixing frame provides a basis for shock absorption and cushioning of the wheel frame. A connecting frame is hinged between the fixing frame and the test vehicle frame. The connecting frame limits the assembly of the fixing frame and the test vehicle frame.

[0015] In one or more embodiments of the present invention, a fixed cover plate is fixedly mounted on top of the assembly frame. The fixed cover plate serves to connect and limit the shock absorber and the assembly frame, facilitating shock absorption of the wheel frame by buffering and limiting the movement of the fixed cover plate. A shock absorber is hinged between the fixed cover plate and the test frame. The shock absorber provides auxiliary support and buffering and limiting for the assembly frame.

[0016] In one or more embodiments of the present invention, multiple sets of friction rollers are mounted at a 45° angle on the outer side of the wheel frame. This facilitates the distribution of the frictional force on the friction rollers through their rotation, thereby aiding in the auxiliary control of the movement direction of the inspection frame. The number of multi-directional moving wheel sets is four. These four sets of multi-directional moving wheel sets provide support, limitation, and multi-directional movement drive for the inspection frame. Within each set of multi-directional moving wheel sets, a pair of friction rollers arranged diagonally within the wheel frame have the same inclination direction. The movement direction of the inspection frame is adjusted and controlled by controlling the rotation direction of the multiple sets of multi-directional moving wheel sets.

[0017] In one or more embodiments of the present invention, a piston block is fixedly connected to one end of the connecting rod located inside the contraction limiting cylinder, and the piston block is slidably engaged with the contraction limiting cylinder. The piston block provides support and limits the connecting rod. A connecting spring is fixedly connected between the piston block and the contraction limiting cylinder. The piston block is supported and limited by the contraction and return of the connecting spring.

[0018] In one or more embodiments of the present invention, a hinge is fixedly connected to the side of the adsorption plate close to the shrinkage limiting cylinder. The end of the hinge facing away from the adsorption plate is spherically shaped, and the hinge is hinged to the connecting rod. By setting one end of the hinge to be spherical, it is easy to make the hinge universally connected to the connecting rod, allowing the adsorption plate to move with multiple degrees of freedom.

[0019] In one or more embodiments of the present invention, the spray marking assembly includes a pair of arc-shaped spray frames, which are fixedly mounted on the bottom of the inspection vehicle frame. Multiple sets of nozzles are assembled and positioned using the pair of arc-shaped spray frames. Both sets of arc-shaped spray frames are hollow. By making the arc-shaped spray frames hollow, it is easier for them to deliver marking liquid to the multiple sets of nozzles, thereby facilitating the marking of bent positions on the members. Multiple sets of evenly distributed nozzles are fixedly mounted below the pair of arc-shaped spray frames, and these nozzles are all connected to the arc-shaped spray frames. The marking liquid is sprayed onto the steel structure frame members through the multiple sets of nozzles, thereby facilitating the marking of bent positions on the members.

[0020] In one or more embodiments of the present invention, a delivery pipe is connected above the pair of arc-shaped spraying frames. The delivery pipe connects the spraying pump and the arc-shaped spraying frames, facilitating the flow and delivery of the marking spray liquid pressurized and extracted by the spraying pump. The spraying pump is fixedly connected to one end of the delivery pipe within the testing vehicle frame, and the delivery pipe is connected to the outlet of the spraying pump. The operation of the spraying pump is controlled to extract and pressurize the marking spray liquid stored in the storage tank for delivery.

[0021] In one or more embodiments of the present invention, the inlet of the spraying pump is connected to a connecting pipe. The connecting pipe connects the spraying pump to a storage tank, facilitating the extraction and delivery of the marking spray liquid stored in the storage tank. The end of the connecting pipe furthest from the spraying pump is connected to the storage tank, which is filled with the marking spray liquid. The storage tank serves to store and collect the marking spray liquid.

[0022] In one or more embodiments of the present invention, a control module is fixedly mounted inside the inspection frame, and the control module is electrically connected to a tilt sensor, a drive motor, and a spray pump. The control module controls the operating status of the tilt sensor, drive motor, and spray pump, thereby facilitating the control of the movement of the inspection frame and the inspection status of the rods.

[0023] Compared with the prior art, the present invention simplifies the process of detecting bending deformation of steel structure space frame members by setting up a multi-directional moving wheel group and controlling the operation of the multi-directional moving wheel group to detect bending deformation of steel structure space frame members in different directions.

[0024] By setting up a magnetic adsorption limiting component, the detection trolley can be assisted in adsorption and limiting, ensuring the stability of the detection trolley's movement on the steel structure space frame members and improving the reliability of bending deformation detection of the steel structure space frame members.

[0025] By setting up a spray marking component, the bending deformation location of steel structure space frame members can be marked by spraying, reducing the adverse effects of environmental and human factors on the bending deformation detection of steel structure space frame members, and significantly improving the efficiency, accuracy and safety of bending detection of steel structure space frame members.

Detailed Implementation

[0038] To enable those skilled in the art to better understand the technical solutions of this invention, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this invention.

[0039] like Figures 1 to 9As shown, the steel structure space frame member buckling deformation detection trolley in one embodiment of the present invention includes: a detection frame 1, an inclination sensor 101, multiple sets of multi-directional moving wheel sets 2, a pair of magnetic adsorption limiting components 3, and a spray marking component 4.

[0040] like Figure 1 As shown, an inclination sensor 101 is fixedly mounted on the lower part of the test frame 1. The inclination sensor 101 detects the inclination data of the steel structure frame members, and the degree of bending deformation of the frame members is judged by the changes in the inclination data.

[0041] Specifically, when the walking angle monitored by the tilt sensor 101 shows a large-small-large or small-large-small change, it is determined that the steel structure space frame member has bending deformation. Furthermore, the greater the angle change detected by the tilt sensor 101, the more severe the bending deformation of the steel structure space frame member is determined. When the angle detected by the tilt sensor 101 does not change or the angle change shows a sawtooth-like small fluctuation, and the angle change amplitude is within the error range, it is determined that the steel structure space frame member does not have bending deformation.

[0042] Preferably, the error range for angle change can be selected according to the actual situation of the steel structure space frame members.

[0043] like Figure 7 As shown, a control module 102 is fixedly installed inside the inspection frame 1. The control module 102 is electrically connected to the tilt sensor 101, the drive motor 202, and the spray pump 404. The control module 102 controls the operating status of the tilt sensor 101, the drive motor 202, and the spray pump 404, thereby facilitating the control of the movement of the inspection frame 1 and the inspection status of the rods.

[0044] like Figures 1 to 5 As shown, multiple sets of multi-directional moving wheel sets 2 are fixedly mounted on the lower part of the inspection vehicle frame 1. These multi-directional moving wheel sets 2 provide support, limit movement, and multi-directional movement for the inspection vehicle frame 1. Each multi-directional moving wheel set 2 includes a mounting frame 201, which is hinged to the bottom of the inspection vehicle frame 1. The mounting frame 201 serves to limit the assembly of the drive motor 202 and the axle 203.

[0045] like Figures 4 to 5 As shown, a fixing bracket 206 is hinged to the side of the assembly frame 201 close to the test frame 1. The fixing bracket 206 serves to limit the assembly of the assembly frame 201. At the same time, the fixing bracket 206 can swing to provide a basis for the shock absorption and cushioning of the wheel frame 204.

[0046] like Figures 4 to 5As shown, a connecting frame 207 is hinged between the fixed frame 206 and the inspection vehicle frame 1. The connecting frame 207 limits the assembly position of the fixed frame 206 and the inspection vehicle frame 1.

[0047] like Figure 6 As shown, a fixed cover plate 208 is fixedly mounted on the top of the assembly frame 201. The fixed cover plate 208 serves to connect and limit the shock absorber 209 and the assembly frame 201, facilitating shock absorption and buffering of the wheel frame 204 by buffering and limiting the fixed cover plate 208.

[0048] like Figure 6 As shown, a shock absorber 209 is hinged between the fixed cover plate 208 and the test vehicle frame 1. The shock absorber 209 provides auxiliary support and buffering limit for the assembly frame 201.

[0049] Among them, shock absorber 209 is commercially available and can be purchased and used directly.

[0050] like Figures 4 to 5 As shown, a drive motor 202 is fixedly mounted inside the assembly frame 201. The drive motor 202 provides power, and by controlling the operation of the drive motor 202, the axle 203 is rotated, thereby facilitating the drive control of multiple sets of wheel frames 204.

[0051] like Figures 1 to 3 As shown, a wheel axle 203 is rotatably connected to the side of the assembly frame 201 opposite to the drive motor 202, and the wheel axle 203 is connected to the output shaft of the drive motor 202. The wheel axle 203 assembles, fixes, and drives the wheel frame 204 to rotate.

[0052] like Figures 4 to 5 As shown, a wheel frame 204 is fixedly mounted on the outer side of the axle 203. The wheel frame 204 is used to limit the assembly of multiple sets of friction rollers 205.

[0053] like Figures 4 to 5 As shown, multiple sets of evenly distributed friction rollers 205 are rotatably connected to the outer side of the wheel frame 204. The multiple sets of friction rollers 205 provide auxiliary support, limit positioning, and drive the movement of the wheel frame 204.

[0054] Specifically, multiple sets of friction rollers 205 are mounted at a 45° angle on the outer side of the wheel frame 204. This facilitates the distribution of the friction force on the friction rollers 205 by rotating them, thereby enabling auxiliary control of the movement direction of the detection frame 1.

[0055] It is worth noting that there are four sets of multi-directional moving wheel sets 2. These four sets of multi-directional moving wheel sets 2 provide support, limit, and multi-directional movement drive for the testing frame 1. Within each set of multi-directional moving wheel sets 2, a pair of friction rollers 205 arranged diagonally within the wheel frame 204 have the same inclination direction. The movement direction of the testing frame 1 is adjusted and controlled by controlling the rotation direction of the multi-directional moving wheel sets 2.

[0056] Specifically, when one pair of diagonally opposite wheel frames 204 rotate in the same direction, and another pair of diagonally opposite wheel frames 204 rotate in the opposite direction, the detection frame 1 will move laterally perpendicular to the wheel frames 204 under the action of the four sets of wheel frames 204; when all four sets of wheel frames 204 rotate around the same direction, the detection frame 1 will move forward or backward under the action of the four sets of wheel frames 204; when only one pair of diagonally opposite wheel frames 204 rotates, the detection frame 1 will rotate and turn around under the action of the four sets of wheel frames 204.

[0057] like Figures 7 to 8 As shown, a pair of magnetic adsorption limiting components 3 are fixedly assembled at the bottom of the testing vehicle frame 1. The magnetic adsorption limiting components 3 include a retractable limiting cylinder 301, which is fixedly assembled inside the testing vehicle frame 1. The retractable limiting cylinder 301 provides support and limits the movement of the connecting rod 302.

[0058] like Figures 7 to 8 As shown, a connecting rod 302 is slidably assembled inside the retraction limiting cylinder 301. The connecting rod 302 limits the assembly of the piston block 306 and the hinge member 308.

[0059] like Figures 7 to 8 As shown, a piston block 306 is fixedly connected to one end of the connecting rod 302 located inside the contraction limiting cylinder 301, and the piston block 306 is in sliding engagement with the contraction limiting cylinder 301. The piston block 306 serves to support and limit the connecting rod 302.

[0060] like Figures 7 to 8 As shown, a connecting spring 307 is fixedly connected between the piston block 306 and the contraction limiting cylinder 301. The piston block 306 is supported and limited by the contraction and reset of the connecting spring 307.

[0061] It is worth noting that under normal conditions, the connecting spring 307 is in a stretched state, which means that the weight of the connecting rod 302, the adsorption plate 303, the flexible adsorption pad 304, the adsorption magnetic bead 305 and the piston block 306 is greater than the tension of the connecting spring 307.

[0062] like Figures 7 to 8As shown, a hinge 308 is fixedly connected to the side of the adsorption plate 303 close to the shrinkage limiting cylinder 301. The end of the hinge 308 facing away from the adsorption plate 303 is spherically shaped, and the hinge 308 is hinged to the connecting rod 302. By making one end of the hinge 308 spherical, it is easy to make the hinge 308 universally connected to the connecting rod 302, so that the adsorption plate 303 can move with multiple degrees of freedom.

[0063] like Figures 7 to 8 As shown, an adsorption plate 303 is hinged to one end of the connecting rod 302 outside the shrinkage limiting cylinder 301. The adsorption plate 303 serves to limit the assembly of the flexible adsorption pad 304.

[0064] like Figures 7 to 8 As shown, a flexible adsorption pad 304 is fixedly connected to the side of the adsorption plate 303 away from the shrinkage limiting cylinder 301. The flexible adsorption pad 304 is used to assemble and limit the multiple sets of adsorption magnetic beads 305. At the same time, the deformation of the flexible adsorption pad 304 can make the multiple sets of adsorption magnetic beads 305 conform to the arc shape of the steel structure frame members.

[0065] like Figures 7 to 8 As shown, the flexible adsorption pad 304 has multiple evenly distributed magnetic beads 305 embedded within it. By using the multiple magnetic beads 305 to adsorb the steel structure frame members, the testing vehicle frame 1 is auxiliaryly limited, ensuring the movement stability of the testing vehicle frame 1.

[0066] like Figures 7 to 9 As shown, the spray marking assembly 4 is fixedly mounted on the outside of the tilt sensor 101, and the spray marking assembly 4 is used to spray marking on the rod.

[0067] like Figures 7 to 9 As shown, the spray marking assembly 4 includes a pair of arc-shaped spray guns 401, which are fixedly mounted on the bottom of the inspection vehicle frame 1. The pair of arc-shaped spray guns 401 are used to limit the assembly of multiple sets of nozzles 402.

[0068] Specifically, both of the arc-shaped spray guns 401 are hollow. By making the arc-shaped spray guns 401 hollow, it is easier for the arc-shaped spray guns 401 to deliver marking spray liquid to multiple sets of nozzles 402, thereby facilitating the spray marking of the bent positions of the rods.

[0069] like Figures 7 to 9 As shown, a pair of arc-shaped spray guns 401 are fixedly mounted below each other with multiple sets of evenly distributed nozzles 402, all of which are connected to the arc-shaped spray guns 401. Marking liquid is sprayed onto the steel structure frame members through the multiple sets of nozzles 402, thus facilitating the marking of the bent positions of the members.

[0070] like Figures 7 to 9As shown, a liquid delivery pipe 403 is connected above a pair of arc-shaped spray guns 401. The liquid delivery pipe 403 serves to connect the spray gun 404 and the arc-shaped spray guns 401, facilitating the flow and delivery of the marking spray liquid pressurized and extracted by the spray gun 404.

[0071] like Figures 7 to 9 As shown, a spraying pump 404 is fixedly connected to one end of the liquid delivery pipe 403 located inside the testing vehicle frame 1, and the liquid delivery pipe 403 is connected to the outlet of the spraying pump 404. The marking spraying liquid stored in the storage tank 406 is extracted and pressurized and delivered by controlling the operation of the spraying pump 404.

[0072] like Figures 7 to 9 As shown, the inlet of the spray pump 404 is connected to a connecting pipe 405. The connecting pipe 405 connects the spray pump 404 to the storage tank 406, facilitating the extraction and delivery of the marking spray liquid stored in the storage tank 406.

[0073] like Figures 7 to 9 As shown, the end of the connecting pipe 405 away from the spray pump 404 is connected to a storage tank 406, which is filled with marking spray liquid. The storage tank 406 serves to store and collect the marking spray liquid.

[0074] In practical use, the testing vehicle 1 is placed on the steel structure frame member to be tested, and the testing vehicle 1 is supported, limited, and driven by four sets of wheel frames 204. Furthermore, multiple sets of magnetic beads 305 will contact the surface of the steel structure frame member under the action of gravity, and simultaneously attract the steel structure frame member through the magnetic beads 305, ensuring the stability of the testing vehicle 1 during movement.

[0075] Subsequently, the control module 102 can control the operation of the drive motors 202 in multiple sets of assembly frames 201 to drive the wheel frame 204 to rotate. Under the action of the friction rollers 205, the multiple sets of wheel frames 204 can drive the inspection frame 1 to move forward, backward, sideways, and rotate, thereby controlling the inspection frame 1 to move on the steel structure space frame members. Furthermore, the tilt angle data of the steel structure space frame members is detected by the tilt angle data of the inspection frame 1, and the tilt angle data of the inspection frame 1 can be used to detect and judge whether the steel structure space frame members are in a bending deformation state.

[0076] When bending deformation is detected in the steel structure space frame members, the control module 102 controls the operation of the spray pump 404 to extract and pressurize the marking spray liquid stored in the storage tank 406, and marks the bending deformation location by spraying the marking spray liquid onto the steel structure space frame members through multiple sets of nozzles 402, thus providing a basis for the subsequent maintenance of the steel structure space frame members.

[0077] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0078] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
