Description

Technical Field

[0001] The invention belongs to the technical field of space positioning of spherical lattice shell steel structure, in particular to a space positioning device of a spherical lattice shell steel structure. Background Art

[0002] The spherical lattice shell steel structure is a special form of building structure. It is composed of multiple rods and nodes connected to form a spatial grid structure. It is usually used in large public buildings, stadiums, exhibition centers and other places. The traditional method of constructing a spherical lattice shell steel structure is to first locate each node through a spatial positioning device, and then connect the rod ends to the nodes by welding to achieve the construction of the spherical lattice shell steel structure.

[0003] The patent with announcement number CN219665568U discloses a steel structure lattice shell processing positioning auxiliary device, including a tooling frame, a positioning tube is rotatably installed on the tooling frame, a bottom sealing plate is clamped on the upper end of the positioning tube, and the bottom sealing plate is fixedly welded to the end of the hub node. The tooling frame is composed of a base and a tooling frame plate. The tooling frame plate is provided with a circle of angle scales distributed around the positioning convex points. The scheme can accurately control the angle of the rotation position of the hub node through the indication of the angle scales, so that the positioning of the hub node is more accurate and faster. Secondly, the tooling frame plate is provided with a positioning convex point, and the bottom end surface of the positioning tube is provided with a positioning groove matched with the positioning convex point. The positioning convex point is embedded in the positioning groove, which is convenient for the staff to connect and separate the hub node and the tooling frame plate.

[0004] In the above scheme, when adjusting the hub node position, due to the large height difference of the hub node on the spherical lattice shell steel structure, the height of the spatial positioning device needs to be adjustable. First of all, the above scheme does not have height adjustment. If the above scheme uses a lifting device, it can achieve up and down height adjustment, but the device needs to be fixed on the lifting device. Once the position of the device is fixed, the position of the device cannot be moved, resulting in reduced flexibility of the device when positioning and adjusting the hub node, making it impossible for staff to quickly locate the position of the hub node, thereby reducing the positioning efficiency of the hub node. For this reason, the present invention provides a spherical lattice shell steel structure spatial positioning device. Summary of the invention

[0007] Through the setting of the magnetic base, the position of the device can be changed at will, increasing the flexibility of the positioning device, which is beneficial for the staff to locate the steel structure node position. Secondly, the setting of the rotary damper, rotary damping shaft, second connecting rod, third connecting rod, and rotary first connecting rod makes it more convenient and flexible for the staff to adjust the steel structure node position, further improving the efficiency of the staff in positioning the steel structure nodes.

[0008] Preferably, an anti-fall mechanism is symmetrically arranged on both sides of the magnetic seat, and the anti-fall mechanism includes an outer shell, the outer shell is fixedly connected to the side of the magnetic seat, an inner shaft is rotatably installed in the outer shell, a coil spring is fixedly sleeved on one end of the inner shaft, an outer ring of the coil spring is fixedly connected to the inner wall of the outer shell, and a steel wire rope is coiled on the inner shaft;

[0009] During the process of moving the positioning device, two sets of steel wire ropes are tied to the steel structure rods, thereby preventing the positioning device from falling from a high altitude.

[0010] Preferably, two sets of guide wheels are rotatably installed in the lower port of the outer shell, and the wire rope is located between the two sets of guide wheels;

[0011] The guide wheel plays a guiding role in dragging the wire rope.

[0012] Preferably, the two groups of steel wire ropes are connected by a docking assembly, which includes a female sleeve, one end of which is fixedly connected to one group of steel wire ropes, one end of which is fixedly connected to another group of steel wire ropes, and two groups of clamping plates fixedly connected to the other end of the male plug, the clamping plates are plugged into the female sleeve, two groups of clamping slots are symmetrically opened on the female sleeve, the clamping plates are clamped into the clamping slots, two groups of avoidance holes are symmetrically opened at one end of the female sleeve, and an unlocking rod is arranged at the end of the clamping plate, and the unlocking rod passes through the avoidance hole;

[0013] The ends of the wire ropes can be connected and separated by plugging and unplugging, making it more convenient for workers to connect and separate the ends of the wire ropes and improving the efficiency of workers in locating steel structure nodes.

[0014] Preferably, a brake assembly is mounted on the other end of the inner rotating shaft, and the brake assembly includes a rotating disk, a middle part of the rotating disk is fixedly connected to the other end of the inner rotating shaft, three groups of slide grooves are provided on the rotating disk at wind angles, a card block is slidably connected to the slide groove, a spring is provided between the slide groove and the card block, one end of the spring is fixedly connected to the card block, and the other end of the spring is fixedly connected to the inner wall of the slide groove, guide grooves are provided on both sides of the slide groove, guide strips are provided on both sides of the card block, and the guide strips are slidably connected to the guide grooves, and the placement assembly also includes a brake ring, which is fixedly installed in the outer shell, the rotating disk is located in the inner ring of the brake ring, and a plurality of groups of limit blocks for blocking the card block are provided on the inner ring of the brake ring;

[0015] Since the brake ring is fixed, as the block moves, the end of the block will press against the limit block on the inner ring of the brake ring. The limit block prevents the block from rotating along with the brake assembly, thereby preventing the positioning device from continuing to fall down, thereby preventing the positioning device from falling too long and affecting the efficiency of the staff in retrieving the positioning device.

[0016] The beneficial effects of the present invention are as follows:

[0017] 1. Through the setting of the magnetic base, the position of the device can be changed at will, which increases the flexibility of the positioning device and is beneficial for the staff to locate the steel structure node position. Secondly, the setting of the rotary damper, the rotary damping shaft, the second connecting rod, the third connecting rod, and the rotating first connecting rod makes it more convenient and flexible for the staff to adjust the steel structure node position, further improving the efficiency of the staff in locating the steel structure node.

[0018] 2. Pull the steel wire ropes on the two sets of anti-fall mechanisms, the steel wire ropes drive the inner rotating shaft to rotate, and the inner rotating shaft twists the coil spring until the ends of the two sets of steel wire ropes are close to each other, and the ends of the two sets of steel wire ropes are twisted together with the help of pliers or other tools to achieve the docking of the two sets of steel wire ropes. When the position of the positioning device is changed, the staff releases the adsorption force of the magnetic seat and moves the positioning device. During the moving process, since the two sets of steel wire ropes are tied to the previous steel structure rods, the steel wire ropes will be dragged, causing the coil spring to be further twisted until the magnetic seat is adsorbed on the next set of steel structure rods, and the connection between the ends of the two sets of steel wire ropes is released. According to the same operation as above, the two sets of steel wire ropes are tied to the next set of steel structure rods. Since the two sets of steel wire ropes are tied to the steel structure rods during the movement of the positioning device, the positioning device is prevented from falling from a high altitude.

[0019] 3. When the positioning device is out of the hands of the staff, under the action of its own gravity, the positioning device pulls the inner shaft together with the brake assembly through the wire rope to rotate rapidly. The short-term rapid rotation will generate a strong centrifugal force, causing the three groups of blocks to move along the corresponding slide grooves back to the inner shaft direction, and the blocks stretch the springs. Since the brake ring is fixed, as the blocks move, the ends of the blocks will resist the limit blocks on the inner ring of the brake ring. The limit blocks prevent the blocks from rotating with the brake assembly, thereby preventing the positioning device from continuing to fall, thereby avoiding the positioning device from falling too long, affecting the efficiency of the staff in retrieving the positioning device.

DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0032] Embodiment 1

[0033] like Figures 1 to 3 As shown, a spherical lattice shell steel structure spatial positioning device according to an embodiment of the present invention comprises a magnetic seat 1 adsorbed on a steel structure rod 7, a second connecting rod 4, a rotary damper 2 is fixedly mounted on the upper end of the magnetic seat 1, the inner ring of the rotary damper 2 is fixedly connected to the lower end of the first connecting rod 3, and rotary damping shafts 5 are arranged at both ends of the second connecting rod 4, one end of a group of rotary damping shafts 5 is connected to the upper end of the first connecting rod 3, and one end of another group of rotary damping shafts 5 is connected to the upper end of the third connecting rod 6, and a placement component 8 for placing a steel structure node 9 is arranged at the lower end of the third connecting rod 6, and a placement component 8 for placing a steel structure node 9 is arranged at the lower end of the third connecting rod 6. Component 8 includes a support 801, which is fixedly connected to the lower end of the third connecting rod 6, a middle part of the support 801 is rotatably connected to the end of the screw 802, a screw sleeve 803 screwed on the screw 802, three groups of internal support members 804 distributed at equal angles around the screw sleeve 803, the internal support member 804 is slidably connected to the guide rail 805, the guide rail 805 is fixedly installed on the support 801, an oblique groove 8041 is opened on the internal support member 804, and three groups of pins 8031 ​​are fixedly installed on the screw sleeve 803, and the three groups of pins 8031 ​​are respectively located in the three groups of oblique grooves 8041.

[0034] Specifically, the reference model of the rotary damper 2 is FDT-47A, and the reference model of the rotary damping shaft 5 is Jen-1012D. In the initial state, the inner diameter surrounded by the three groups of inner support members 804 is smaller than the inner diameter of the steel structure node 9. When the position of the steel structure node 9 needs to be positioned, the magnetic seat 1 is first placed on the steel structure rod 7 to which the steel structure node 9 needs to be welded, and then the knob on the magnetic seat 1 is screwed so that the magnetic seat 1 is tightly adsorbed on the steel structure rod 7. Then, the steel structure node 9 is sleeved on the three groups of inner support members 804, and the screw 802 is rotated to move the screw sleeve 803 toward the support 801. At the same time, the three groups of pins 8031 ​​move with the screw sleeve 803, and the moving pins 8031 ​​squeeze the inner wall of the oblique groove 8041, so that the inner support member 804 moves along the guide rail 805 away from the screw 802. The three groups of inner support members 804 will squeeze the steel structure node 9 at the same time. The inner wall is used to limit the steel structure node 9, and then the second connecting rod 4, the third connecting rod 6 or the rotating first connecting rod 3 is moved, so that the steel structure node 9 can be accurately moved to the position point welded with the steel structure rod 7. Since the rotary damper 2 and the rotary damping shaft 5 have a damping effect on the second connecting rod 4, the third connecting rod 6, and the rotating first connecting rod 3, the position of the steel structure node 9 is not easy to change, thereby realizing the positioning of the steel structure node 9. Compared with the prior art, through the setting of the magnetic seat 1, the position of the device can be changed at will, the flexibility of the positioning device is increased, which is beneficial for the staff to locate the position of the steel structure node 9. Secondly, the setting of the rotary damper 2, the rotary damping shaft 5, the second connecting rod 4, the third connecting rod 6, and the rotating first connecting rod 3 makes it more convenient and flexible for the staff to adjust the position of the steel structure node 9, further improving the efficiency of the staff in positioning the steel structure node 9.

[0035] like Figure 4 and Figure 5 As shown, anti-fall mechanisms 10 are symmetrically arranged on both sides of the magnetic base 1, and the anti-fall mechanism 10 includes an outer shell 101, the outer shell 101 is fixedly connected to the side of the magnetic base 1, an inner shaft 102 is rotatably installed in the outer shell 101, a coil spring 103 is fixedly sleeved on one end of the inner shaft 102, the outer ring of the coil spring 103 is fixedly connected to the inner wall of the outer shell 101, and a wire rope 104 is coiled on the inner shaft 102.

[0036] Specifically, after positioning one set of steel structure nodes 9, the next set needs to be replaced, so the position of the positioning device needs to be replaced. Since the positioning device is in a high position, if the operator makes an operational error when operating the positioning device and the positioning device slips out of the operator's hand, the positioning device will fall from a high altitude, which will not only cause the positioning device to be broken, but also the falling positioning device will easily injure the operator. Therefore, after the magnetic seat 1 is adsorbed on the steel structure rod 7, the steel wire rope 104 on the two sets of anti-fall mechanisms 10 is pulled, and the steel wire rope 104 drives the inner rotating shaft 102 to rotate, and the inner rotating shaft 102 twists the coil spring 103 until the ends of the two sets of steel wire ropes 104 are close to each other, and the two sets of steel wire ropes are fixed together with the help of pliers or other tools. The ends of 104 are screwed together to achieve the docking of the two groups of steel wire ropes 104. When the position of the positioning device is changed, the staff releases the adsorption force of the magnetic base 1 and moves the positioning device. During the movement, since the two groups of steel wire ropes 104 are tied to the previous steel structure rod 7, the steel wire ropes 104 will be dragged, causing the coil spring 103 to be further screwed until the magnetic base 1 is adsorbed on the next group of steel structure rods 7, and the connection between the ends of the two groups of steel wire ropes 104 is released. Following the same operation as above, the two groups of steel wire ropes 104 are tied to the next group of steel structure rods 7. Since the two groups of steel wire ropes 104 are tied to the steel structure rods 7 during the movement of the positioning device, the positioning device is prevented from falling from a high altitude.

[0037] Furthermore, two sets of guide wheels 105 are rotatably installed in the lower port of the outer shell 101 , and the wire rope 104 is located between the two sets of guide wheels 105 .

[0038] Specifically, during the process of dragging the steel wire rope 104 , the steel wire rope 104 drives the two sets of guide wheels 105 to rotate, and the guide wheels 105 play a guiding role in dragging the steel wire rope 104 .

[0039] Embodiment 2

[0040] like Figure 6 and Figure 7 As shown, compared with Example 1, another implementation of the present invention is: two groups of steel wire ropes 104 are connected by a docking assembly 106, and the docking assembly 106 includes a female sleeve 1061, one end of the female sleeve 1061 is fixedly connected to one group of steel wire ropes 104, one end of the male plug 1062 is fixedly connected to the other group of steel wire ropes 104, two groups of clamping plates 1063 are fixedly connected to the other end of the male plug 1062, the clamping plate 1063 is plugged into the female sleeve 1061, two groups of clamping grooves 1064 are symmetrically opened on the female sleeve 1061, the clamping plate 1063 is clamped into the clamping groove 1064, two groups of avoidance holes 1066 are symmetrically opened at one end of the female sleeve 1061, and an unlocking rod 1065 is provided at the end of the clamping plate 1063, and the unlocking rod 1065 passes through the avoidance hole 1066.

[0041] Specifically, the clamping plate 1063 is made of stainless steel with good elasticity. When the ends of the two sets of steel wire ropes 104 are docked or separated, tools are required, which makes it troublesome to dock or separate the ends of the two sets of steel wire ropes 104, affecting the efficiency of the workers in positioning the steel structure node 9. Therefore, when the ends of the two sets of steel wire ropes 104 are docked, the two sets of clamping plates 1063 are inserted into the female sleeve 1061, and the ends of the clamping plates 1063 are squeezed by the end portion of the female sleeve 1061, so that the clamping plates 1063 are bent and deformed until they are deformed under the action of the rebound force of the clamping plates 1063. The clamping plate 1063 is clamped with the clamping groove 1064 on the mother sleeve 1061, so as to realize the docking of the ends of the two groups of steel wire ropes 104. When the ends of the two groups of steel wire ropes 104 are to be separated, the two groups of unlocking rods 1065 are pressed toward each other to release the clamping of the two groups of clamping plates 1063 from the clamping groove 1064, and then the two groups of clamping plates 1063 can be pulled out from the mother sleeve 1061. Therefore, the ends of the steel wire ropes 104 can be docked and separated by plugging and unplugging, which makes it more convenient for the workers to dock and separate the ends of the steel wire ropes 104, and improves the efficiency of the workers in positioning the steel structure nodes 9.

[0042] like Figure 8 and Fig. 9 As shown, the other end of the inner rotating shaft 102 is provided with a brake assembly 107, and the brake assembly 107 includes a rotating disk 1071, the middle of the rotating disk 1071 is fixedly connected to the other end of the inner rotating shaft 102, three sets of sliding grooves 1072 are provided on the rotating disk 1071, and a block 1073 is slidably connected to the sliding groove 1072. A spring 1074 is provided between the sliding groove 1072 and the block 1073, and one end of the spring 1074 is fixedly connected to the block 1073, and the other end of the spring 1074 is fixedly connected to the block 1073. The inner wall of the fixedly connected slide groove 1072, guide grooves 721 are opened on both sides of the slide groove 1072, guide strips 731 are arranged on both sides of the block 1073, the guide strips 731 are slidably connected to the guide grooves 721, the placement component 8 also includes a brake ring 108, the brake ring 108 is fixedly installed in the outer shell 101, the rotating disk 1071 is located in the inner ring of the brake ring 108, and a plurality of groups of limit blocks 1081 for blocking the block 1073 are arranged on the inner ring of the brake ring 108.

[0043] Specifically, when the positioning device falls, the wire rope 104 will be pulled until the wire rope 104 wrapped around the inner shaft 102 is completely pulled out, so that the positioning device is suspended in the air. Since the wire rope 104 is long, the staff's hands cannot reach the positioning device, which makes it difficult for the staff to retract the positioning device. Therefore, when the positioning device is out of the staff's hands, under the action of the positioning device's own gravity, the positioning device pulls the inner shaft 102 together with the brake assembly 107 to rotate rapidly through the wire rope 104. The short-term rapid rotation will A strong centrifugal force is generated, causing the three groups of blocks 1073 to move along the corresponding slide grooves 1072 in the direction away from the inner rotating shaft 102, and the blocks 1073 stretch the springs 1074. Since the brake ring 108 is fixed, as the blocks 1073 move, the ends of the blocks 1073 will abut against the limit blocks 1081 on the inner ring of the brake ring 108. The limit blocks 1081 prevent the blocks 1073 from rotating along with the brake assembly 107, thereby preventing the positioning device from continuing to fall downward, thereby preventing the positioning device from falling too long a distance, affecting the efficiency of the staff in retrieving the positioning device.

[0044] Working principle: First, place the magnetic seat 1 on the steel structure rod 7 to which the steel structure node 9 needs to be welded, then turn the knob on the magnetic seat 1 to make the magnetic seat 1 tightly adsorbed on the steel structure rod 7, then put the steel structure node 9 on the three sets of inner support members 804, rotate the screw 802, so that the screw sleeve 803 moves toward the support 801, and at the same time, the three sets of pins 8031 ​​move with the screw sleeve 803, and the moving pins 8031 ​​squeeze the inner wall of the oblique groove 8041, so that the inner support member 804 moves along the guide rail 805 away from the inner support member 804. When the screw rod 802 moves, the three groups of inner support members 804 will squeeze the inner wall of the steel structure node 9 at the same time to limit the position of the steel structure node 9, and then the second connecting rod 4, the third connecting rod 6 or the first connecting rod 3 are moved, so that the steel structure node 9 can be accurately moved to the position point welded with the steel structure rod 7. Since the rotary damper 2 and the rotary damping shaft 5 have a damping effect on the second connecting rod 4, the third connecting rod 6 and the rotating first connecting rod 3, the position of the steel structure node 9 is not easy to change, thereby realizing the positioning of the steel structure node 9;

[0045] When the ends of the two groups of steel wire ropes 104 are butted together, the two groups of clamping plates 1063 are inserted into the female sleeve 1061, and the ends of the clamping plates 1063 are squeezed by the end portion of the female sleeve 1061, so that the clamping plates 1063 are bent and deformed, until the clamping plates 1063 are clamped into the clamping grooves 1064 on the female sleeve 1061 under the action of the rebound force of the clamping plates 1063, so as to achieve the butt connection of the ends of the two groups of steel wire ropes 104. When the ends of the two groups of steel wire ropes 104 are separated, the two groups of unlocking rods 1065 are pressed toward each other to release the clamping of the two groups of clamping plates 1063 from the clamping grooves 1064, and then the two groups of clamping plates 1063 are pulled out from the female sleeve 1061.

[0046] When the positioning device is out of the hands of the staff, under the action of its own gravity, the positioning device pulls the inner rotating shaft 102 together with the brake assembly 107 through the wire rope 104 to rotate rapidly. The short-term rapid rotation will generate a strong centrifugal force, causing the three groups of blocks 1073 to move along the corresponding slide grooves 1072 away from the inner rotating shaft 102, and the blocks 1073 stretch the springs 1074. Since the brake ring 108 is fixed, as the block 1073 moves, the end of the block 1073 will resist the limit block 1081 on the inner ring of the brake ring 108. The limit block 1081 prevents the block 1073 from rotating along with the brake assembly 107, thereby preventing the positioning device from continuing to fall.

[0047] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
