Description

Technical Field

[0001] The invention belongs to the technical field of steel structure grid deformation detection, and in particular relates to a trolley for detecting buckling deformation of steel structure grid rods. Background Art

[0002] Steel structure grid is a type of spatial structure composed of multiple rods connected by nodes in a certain grid form. It has the advantages of small spatial force, light weight, high rigidity and good seismic performance. It is widely used in large space construction fields such as gymnasiums, theaters, exhibition halls, waiting halls, etc.

[0003] Since steel structure grids are mainly used as roofs for large-space buildings, and large-space buildings mean that people will gather, the safety and stability of the use of steel structure grids is particularly important. Rod bending and deformation is a common problem in the actual application of steel structure grids. Rod bending and deformation will not only reduce the overall stiffness of the steel structure grid, but in severe cases will cause the steel structure grid to deform and collapse as a whole. Therefore, regular bending and deformation detection of steel structure grid rods plays a vital role in the safe use of steel structure grids.

[0004] At present, the existing technology mainly adopts the method of manual wire pulling and plumb bob to detect whether the steel structure grid rods are bent and deformed. Due to the large number of steel structure grid rods, this method is less efficient in detecting the steel structure grid rods. At the same time, the detection process is easily affected by various factors such as environmental factors and human factors, resulting in incomplete and inaccurate detection results. In addition, since the steel structure grid rods are generally erected at a high altitude, the manual detection method has great safety hazards.

[0005] The information disclosed in this background technology section is only intended to enhance the understanding of the overall background of the invention and should not be regarded as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art. Summary of the invention

[0006] The object of the present invention is to provide a trolley for detecting buckling deformation of steel structure grid rods, which can improve the efficiency, accuracy and safety of bending detection of steel structure grid rods.

[0007] In order to achieve the above object, a technical solution provided by a specific embodiment of the present invention is as follows:

[0008] The buckling deformation detection vehicle for steel structure grid rods comprises: a detection frame, an inclination sensor, a plurality of multi-directional movable wheel groups, a pair of magnetic adsorption limit components, and a spray marking component.

[0009] An inclination sensor is fixedly mounted below the detection frame, and the inclination data of the steel structure grid rods is detected by the inclination sensor, and the bending deformation degree of the grid rods is judged by the change of the inclination data of the grid rods.

[0010] The specific judgment method is: when the walking angle monitored by the inclination sensor shows a change of large-small-large or small-large-small, it is judged that the steel structure truss rod has bending deformation, and the greater the angle change detected by the inclination sensor, the more serious the bending deformation of the steel structure truss rod; when the angle detected by the inclination sensor does not change or the angle change fluctuates in a small sawtooth shape, and the angle change amplitude is within the error range, it is judged that the steel structure truss rod does not have bending deformation.

[0011] A plurality of groups of the multi-directional movable wheel groups are fixedly mounted below the detection frame, and the multi-directional movable wheel groups include an assembly frame, which is hinged at the bottom of the detection frame, and a driving motor is fixedly mounted inside the assembly frame, and a wheel axle is rotatably connected to the side of the assembly frame away from the driving motor, and the wheel axle is drivingly connected to the output shaft of the driving motor, and a wheel frame is fixedly mounted on the outer side of the wheel axle, and a plurality of groups of evenly distributed friction rollers are rotatably connected to the outer side of the wheel frame.

[0012] A pair of magnetic adsorption limit assemblies are fixedly assembled at the bottom of the detection frame, and the magnetic adsorption limit assembly includes a contraction limit cylinder, which is fixedly assembled in the detection frame, and a connecting rod is slidably assembled in the contraction limit cylinder, and an adsorption plate is hinged at one end of the connecting rod located outside the contraction limit cylinder, and a flexible adsorption pad is fixedly connected to the side of the adsorption plate away from the contraction limit cylinder, and a plurality of evenly distributed adsorption magnetic beads are embedded in the flexible adsorption pad.

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

[0014] In one or more embodiments of the present invention, a fixing frame is hingedly connected to one side of the assembly frame close to the detection frame. The fixing frame is used to limit the assembly position of the assembly frame. At the same time, the swinging of the fixing frame can provide a basis for shock absorption and buffering of the wheel frame. A connecting frame is hingedly installed between the fixing frame and the detection frame. The fixing frame and the detection frame are limited by the connecting frame.

[0015] In one or more embodiments of the present invention, a fixed cover plate is fixedly mounted above the assembly frame. The fixed cover plate serves as a connection limiter for the shock absorber and the assembly frame, so that the wheel frame can be damped and buffered by buffering and limiting the fixed cover plate. A shock absorber is hingedly mounted between the fixed cover plate and the detection frame. The shock absorber serves as an auxiliary support and buffering limiter for the assembly frame.

[0016] In one or more embodiments of the present invention, multiple groups of friction rollers are installed on the outside of the wheel frame at an angle of 45°. It is convenient to divide the friction force on the friction roller by the self-rotation of the friction roller, so as to facilitate the auxiliary control of the moving direction of the detection frame. The number of the multi-directional moving wheel groups is 4. The detection frame is supported, limited and driven in multi-directional movement by 4 groups of multi-directional moving wheel groups. A pair of multiple groups of friction rollers in the wheel frame arranged along the diagonal line in the multiple groups of multi-directional moving wheel groups have the same inclination direction. The moving direction of the detection frame is adjusted and controlled by controlling the rotation direction of the multiple groups of multi-directional moving wheel groups.

[0017] In one or more embodiments of the present invention, one end of the connecting rod located in the shrinkage limit cylinder is fixedly connected to a piston block, and the piston block is slidably matched with the shrinkage limit cylinder. The piston block plays a role of supporting and limiting the connecting rod. A connecting spring is fixedly connected between the piston block and the shrinkage limit cylinder. The piston block is supported and limited by the contraction and reset of the connecting spring.

[0018] In one or more embodiments of the present invention, a hinge is fixedly connected to one side of the adsorption plate close to the shrinkage limit cylinder, and the end of the hinge facing away from the adsorption plate is spherical, and the hinge is hinged to the connecting rod. By setting one end of the hinge to be spherical, it is convenient to make the hinge universally connected to the connecting rod, so that the adsorption plate can 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 racks, and the pair of arc-shaped spray racks are fixedly assembled at the bottom of the inspection vehicle frame. A plurality of groups of nozzles are assembled and limited by a pair of arc-shaped spray racks. A pair of arc-shaped spray racks are both hollow. By setting the arc-shaped spray racks to be hollow, it is convenient for the arc-shaped spray racks to transport marking spray liquid to the plurality of groups of nozzles, thereby facilitating spray marking of the bending positions of the rods. A plurality of groups of evenly distributed nozzles are fixedly assembled below the pair of arc-shaped spray racks, and the plurality of groups of nozzles are connected to the arc-shaped spray racks. The marking spray liquid is sprayed onto the steel structure grid rods by the plurality of groups of nozzles, thereby facilitating spray marking of the bending positions of the rods.

[0020] In one or more embodiments of the present invention, a pair of arc-shaped spray racks are connected with a liquid delivery pipe above. The liquid delivery pipe serves to connect the spray pump and the arc-shaped spray rack, so as to facilitate the diversion and delivery of the marking spray liquid pressurized and extracted by the spray pump. The end of the liquid delivery pipe located in the detection vehicle frame is fixedly connected to the spray pump, and the liquid delivery pipe is connected to the liquid outlet of the spray pump. The marking spray liquid stored in the liquid storage tank is extracted and pressurized by controlling the operation of the spray pump.

[0021] In one or more embodiments of the present invention, the liquid inlet of the spray pump is connected to a connecting liquid pipe. The connecting liquid pipe serves to connect the spray pump with the liquid storage tank, so as to facilitate the extraction and transportation of the marking spray liquid stored in the liquid storage tank. The end of the connecting liquid pipe away from the spray pump is connected to the liquid storage tank, and the liquid storage tank is filled with the marking spray liquid. The liquid storage tank serves to store the marking spray liquid.

[0022] In one or more embodiments of the present invention, a control module is fixedly installed in the detection frame, and the control module is electrically connected to the inclination sensor, the drive motor and the spray pump. The control module controls the operating state of the inclination sensor, the drive motor and the spray pump, thereby facilitating the control of the movement of the detection frame and the rod detection state.

[0023] Compared with the prior art, the present invention simplifies the process of bending deformation detection of steel structure grid rods by setting a multi-directional moving wheel group and controlling the operation of the multi-directional moving wheel group to detect bending deformation of steel structure grid rods in different directions;

[0024] By setting up a magnetic adsorption limit component, the detection trolley can be auxiliary adsorbed and limited, ensuring the stability of the detection trolley moving on the steel structure grid rods and improving the reliability of bending deformation detection of steel structure grid rods;

[0025] By setting up a spray marking component, the bending deformation positions of steel structure grid rods can be spray marked, reducing the adverse effects of environmental and human factors on the bending deformation detection of steel structure grid rods, and significantly improving the efficiency, accuracy and safety of bending detection of steel structure grid rods.

DETAILED DESCRIPTION

[0038] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

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

[0040] like Figure 1 As shown, a tilt sensor 101 is fixedly mounted below the detection frame 1. The tilt sensor 101 detects the tilt data of the steel structure grid rods, and determines the bending deformation degree of the grid rods by the change of the tilt data of the grid rods.

[0041] Specifically, when the walking angle monitored by the inclination sensor 101 shows a change of large-small-large or small-large-small, it is determined that the steel structure truss rod has bending deformation, and the greater the change in the angle detected by the inclination sensor 101, the more serious the bending deformation of the steel structure truss rod is; when the angle detected by the inclination sensor 101 does not change or the angle changes in a small sawtooth fluctuation, and the amplitude of the angle change is within the error range, it is determined that the steel structure truss rod does not have bending deformation.

[0042] Preferably, the error determination range of the angle change can be selected according to the actual conditions of the steel structure grid members.

[0043] like Figure 7 As shown, a control module 102 is fixedly installed in the detection frame 1, and the control module 102 is electrically connected to the inclination sensor 101, the drive motor 202 and the spray pump 404. The control module 102 controls the operating states of the inclination sensor 101, the drive motor 202 and the spray pump 404, so as to facilitate the control of the movement of the detection frame 1 and the rod detection state.

[0044] like Figures 1 to 5 As shown, multiple sets of multi-directional movable wheel groups 2 are fixedly assembled below the detection frame 1. The detection frame 1 is supported, limited and moved in multiple directions by multiple sets of multi-directional movable wheel groups 2. The multi-directional movable wheel group 2 includes an assembly frame 201, which is hinged at the bottom of the detection frame 1. The assembly frame 201 plays the role of assembling and limiting the driving motor 202 and the wheel axle 203.

[0045] like Figures 4 to 5 As shown, a fixing frame 206 is hingedly connected to one side of the assembly frame 201 close to the detection frame 1. The fixing frame 206 plays a role of assembly limit for the assembly frame 201. At the same time, the swinging of the fixing frame 206 can provide a basis for the shock absorption and buffering of the wheel frame 204.

[0046] like Figures 4 to 5As shown, a connecting frame 207 is hingedly assembled between the fixing frame 206 and the detection frame 1. The fixing frame 206 and the detection frame 1 are assembled and limited by the connecting frame 207.

[0047] like Figure 6 As shown, a fixed cover plate 208 is fixedly mounted on the assembly frame 201. The fixed cover plate 208 serves to connect and limit the shock absorber 209 and the assembly frame 201, so as to facilitate the 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 hingedly mounted between the fixed cover plate 208 and the detection frame 1. The shock absorber 209 plays the role of auxiliary support and buffering limit for the assembly frame 201.

[0049] The 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 in the assembly frame 201. The drive motor 202 provides power, and the wheel axle 203 is driven to rotate by controlling the operation of the drive motor 202, so as to facilitate driving and controlling the multiple groups of wheel frames 204.

[0051] like Figures 1 to 3 As shown, the side of the assembly frame 201 away from the driving motor 202 is rotatably connected to the axle 203, and the axle 203 is drivingly connected to the output shaft of the driving motor 202. The axle 203 assembles, fixes and rotates the wheel frame 204.

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

[0053] like Figures 4 to 5 As shown, the outer side of the wheel frame 204 is rotatably connected with multiple groups of evenly distributed friction rollers 205. The wheel frame 204 is auxiliary supported, limited and driven to move by multiple groups of friction rollers 205.

[0054] Specifically, multiple groups of friction rollers 205 are installed at an angle of 45° on the outside of the wheel frame 204. The friction rollers 205 can be rotated to divide the friction force on the friction rollers 205, thereby assisting in controlling the moving direction of the detection frame 1.

[0055] It is worth noting that there are 4 sets of multi-directional moving wheel sets 2. The detection frame 1 is supported, limited and driven in multi-directional movement by the 4 sets of multi-directional moving wheel sets 2. The multiple sets of friction rollers 205 in a pair of diagonally arranged wheel frames 204 in the multiple sets of multi-directional moving wheel sets 2 have the same inclination direction. The moving direction of the detection frame 1 is adjusted and controlled by controlling the rotation direction of the multiple sets of multi-directional moving wheel sets 2.

[0056] Among them, when a pair of wheel frames 204 at diagonal positions rotate in the same direction and another pair of wheel frames 204 at diagonal positions rotate in the opposite direction to the previous pair, the detection frame 1 will make a lateral movement perpendicular to the wheel frames 204 under the action of the four groups of wheel frames 204; when the four groups of wheel frames 204 all rotate in the same direction, the detection frame 1 will move forward or backward under the action of the four groups of wheel frames 204; when only a pair of wheel frames 204 at diagonal positions rotates, the detection frame 1 will rotate and turn around under the action of the four groups of wheel frames 204.

[0057] like Figures 7 and 8 As shown, a pair of magnetic adsorption limiting components 3 are fixedly assembled at the bottom of the detection frame 1, and the magnetic adsorption limiting components 3 include a contraction limiting cylinder 301, which is fixedly assembled in the detection frame 1. The contraction limiting cylinder 301 supports and moves the connecting rod 302.

[0058] like Figures 7 and 8 As shown, a connecting rod 302 is slidably mounted in the contraction limiting cylinder 301. The connecting rod 302 performs assembly and positioning of the piston block 306 and the hinge 308.

[0059] like Figures 7 and 8 As shown, one end of the connecting rod 302 located in the shrinkage limiting cylinder 301 is fixedly connected with a piston block 306, and the piston block 306 is slidably matched with the shrinkage limiting cylinder 301. The piston block 306 plays a role of supporting and limiting the connecting rod 302.

[0060] like Figures 7 and 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, that is, the gravity of the connecting rod 302 , the adsorption plate 303 , the flexible adsorption pad 304 , the adsorption magnetic beads 305 and the piston block 306 is greater than the tension of the connecting spring 307 .

[0062] like Figures 7 and 8As shown, a hinge 308 is fixedly connected to one side of the adsorption plate 303 close to the contraction limiting cylinder 301, and one end of the hinge 308 facing away from the adsorption plate 303 is spherical, and the hinge 308 is hinged to the connecting rod 302. By setting one end of the hinge 308 in a spherical shape, it is convenient 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 and 8 As shown, one end of the connecting rod 302 outside the shrinkage limiting cylinder 301 is hinged with an adsorption plate 303. The adsorption plate 303 plays a role of assembly limiting for the flexible adsorption pad 304.

[0064] like Figures 7 and 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 groups of adsorption magnetic beads 305. At the same time, the multiple groups of adsorption magnetic beads 305 can fit the arc shape of the steel structure grid rod through the deformation of the flexible adsorption pad 304.

[0065] like Figures 7 and 8 As shown, a plurality of uniformly distributed adsorption magnetic beads 305 are embedded in the flexible adsorption pad 304. The detection frame 1 is auxiliary limited by the adsorption of the steel structure grid rods by the plurality of adsorption magnetic beads 305, thereby ensuring the movement stability of the detection frame 1.

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

[0067] like Figures 7 to 9 As shown, the spray marking assembly 4 includes a pair of arc-shaped spray racks 401, and the pair of arc-shaped spray racks 401 are fixedly assembled at the bottom of the detection vehicle frame 1. The plurality of nozzle groups 402 are assembled and limited by the pair of arc-shaped spray racks 401.

[0068] Specifically, the pair of arc-shaped spray racks 401 are both hollow. By arranging the arc-shaped spray racks 401 to be hollow, it is convenient for the arc-shaped spray racks 401 to deliver marking spray liquid to the multiple groups of nozzles 402, thereby facilitating spray marking of the bending positions of the rods.

[0069] like Figures 7 to 9 As shown, a pair of arc-shaped spray racks 401 are fixedly mounted with multiple sets of uniformly distributed nozzles 402 below, and the multiple sets of nozzles 402 are all connected to the arc-shaped spray racks 401. The marking spray liquid is sprayed onto the steel structure grid rods through the multiple sets of nozzles 402, so as to facilitate spray marking of the bending positions of the rods.

[0070] like Figures 7 to 9As shown, a pair of arc-shaped spray racks 401 are connected with a liquid delivery pipe 403 above. The liquid delivery pipe 403 serves to connect the spray pump 404 with the arc-shaped spray rack 401, so as to facilitate the diversion and delivery of the marking spray liquid pressurized and extracted by the spray pump 404.

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

[0072] like Figures 7 to 9 As shown, the liquid inlet of the spray pump 404 is connected with a connecting liquid pipe 405. The connecting liquid pipe 405 serves to connect the spray pump 404 with the liquid storage tank 406, so as to facilitate the extraction and transportation of the marking spray liquid stored in the liquid storage tank 406.

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

[0074] When in use, the detection vehicle frame 1 is placed on the steel structure grid rod to be detected, and the detection vehicle frame 1 is supported, limited and driven by the four sets of wheel frames 204. In addition, the multiple sets of adsorption magnetic beads 305 will contact the surface of the steel structure grid rod under the action of gravity, and the steel structure grid rod is adsorbed by the multiple sets of adsorption magnetic beads 305, thereby ensuring the stability of the movement detection of the detection vehicle frame 1.

[0075] Subsequently, the control module 102 can be used to control the operation of the driving motors 202 in the multiple assembly frames 201 to drive the wheel frames 204 to rotate. Under the action of the friction rollers 205, the multiple wheel frames 204 can drive the detection frame 1 to move forward, backward, sideways, and rotate and turn around in multiple directions, thereby controlling the detection frame 1 to move on the steel structure grid rods. In addition, the inclination data of the steel structure grid rods is detected by the inclination sensor 101, and it can be detected and judged whether the steel structure grid rods are in a bending deformation state based on the inclination data of the detection frame 1.

[0076] When bending deformation is detected in the steel structure grid rod, the control module 102 controls the operation of the spray pump 404 to extract and pressurize the marking spray liquid stored in the liquid storage tank 406, and the marking spray liquid is sprayed on the steel structure grid rod by multiple groups of nozzles 402 to mark the bending deformation position, thereby providing a basis for subsequent maintenance of the steel structure grid rod.

[0077] It will be apparent to those skilled in the art that the 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 the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
