Description

Technical Field

[0001] The invention relates to the technical field of steel structure connecting pieces, and in particular to an adjustable steel structure connecting device. Background Art

[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. Its structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. Among them, steel structure connection refers to the mutual connection between steel structure components or parts, and steel structure connectors are necessary components for connecting two steel materials.

[0003] Steel structure connection devices are designed to achieve dynamic adjustment between steel structure components to adapt to different loads and environmental conditions. However, at present, most steel structure connection methods are welded, bolted or rivet. Although the above connection methods can meet general strength requirements and basic connection requirements, they cannot adjust the position of the steel structure. For example, steel structure connections at high places require workers to climb up to the height to fix the steel structure connection devices through bolts and other means.

[0004] Furthermore, when the height of the steel structure needs to be adjusted, bolt connection may increase the difficulty of disassembly, making the flexibility of steel structure adjustment reduced. At the same time, during the construction of the bridge, if a steel structure connection device is used for fixing, the staff will need to use climbing equipment to climb to a high place and then adjust and fix the steel structure connection device by bolts or welding. Manual work at heights not only poses a safety hazard, but also the height of the steel structure will be affected by the wind, requiring manual adjustment and correction of the steel parts until they reach the designated connection point. Bolting or welding can be performed, which is time-consuming, labor-intensive and inefficient. Therefore, the present invention solves the shortcomings of the above technical problems. Summary of the invention

[0005] Based on the above existing technical problems, the present invention proposes an adjustable steel structure connection device.

[0006] The present invention proposes an adjustable steel structure connection device, including a supporting steel base, the upper surface of the steel base is fixedly connected to a supporting beam steel with a cavity inside, both side surfaces of the supporting beam steel are penetrated by sliding holes, the inner sides of the sliding holes on both sides are slidably clamped with cross steels for connecting steel structure columns, a climbing mechanism is arranged inside the supporting beam steel, and a locking mechanism is arranged on the end face of the climbing mechanism.

[0007] Wherein, the climbing mechanism is connected to the cross steel, and the climbing mechanism includes an I-beam arranged inside the support beam steel, and the I-beam drives the cross steel to adjust its height when the inner surface of the support beam steel moves linearly.

[0008] Wherein, the locking mechanism is activated after the climbing mechanism completes the adjustment, and the locking mechanism includes an octagonal foot, which is connected to the support beam steel after the end surface of the I-beam is opened, thereby locking the position of the I-beam.

[0009] Preferably, the climbing mechanism further comprises a rack rod symmetrically distributed and fixedly connected to the inner surface of the support beam steel, and the outer surface of the I-beam is slidably connected to one side surface of the rack rod.

[0010] Through the above technical solution, in order to guide the height adjustment of the I-beam, the end faces of the I-beam are limited by symmetrical rack rods so that the I-beam can maintain movement on the vertical line, and the rack rod serves as a climbing path for the I-beam.

[0011] Preferably, the climbing mechanism further comprises climbing gears symmetrically distributed on both side surfaces of the I-beam, the climbing gears are rotatably connected to the surface of the I-beam via a rotating shaft, and the climbing gears are meshed with the rack rod.

[0012] Through the above technical scheme, in order to realize the height adjustment of the cross steel driven by the I-beam, thereby facilitating the connection between the cross steel and the steel structure column, the two rotating shafts rotate simultaneously, driving the four climbing gears to rotate synchronously, so that the climbing gears climb on the outer surface of the rack rod, thereby realizing the height adjustment of the I-beam.

[0013] Preferably, the climbing mechanism also includes a first pulley assembly installed on the outer surface of one end of the two rotating shafts, wherein a transmission gear is fixedly sleeved on the outer surface of the other end of one of the rotating shafts, a reduction motor is fixedly installed on one side surface of the I-beam, and the outer surface of the output shaft of the reduction motor is fixedly connected to a driving gear through a coupling, and the driving gear is meshed with the transmission gear.

[0014] Through the above technical solution, in order to control the rotation of the four climbing gears to realize the movement of the I-beam, when the reduction motor controls the driving gear to rotate, it can drive the transmission gear to rotate, so that the transmission gear drives one of the rotating shafts to rotate, and then the other rotating shaft can be controlled to rotate under the transmission of the first pulley assembly, so that the four climbing gears climb on the outer surface of the rack rod.

[0016] Through the above technical solution, in order to fix the position of the I-beam after it moves, the front end of the adjusting screw moves on the inner wall of the guide groove when the I-beam moves. When the I-beam stops moving, the adjusting screw extends forward to the inside of the installation cavity and engages with the inside of the cavity to lock the I-beam.

[0017] Preferably, the locking mechanism also includes a groove shell fixedly connected to the inner wall of the installation cavity, the inner wall of the groove shell is symmetrically distributed and fixedly connected with a clamping plate, the octopus feet are distributed in a circular array and hingedly installed on the free end face of the adjusting screw, and the outer surface of the octopus feet is slidably connected to the inner wall of the groove shell and the surface of the clamping plate respectively.

[0018] Through the above technical scheme, in order to achieve the effect of locking the I-beam when the adjusting screw is extended, when the adjusting screw moves forward, the hinged octagonal foot is gradually spread open, and the support foot abuts against the inner wall of the groove shell and the surface of the clamping plate, so that the octagonal foot is restricted from moving, thereby achieving the locking effect.

[0019] Preferably, a ball bearing is installed on the free end surface of the octopus foot, a return spring is fixedly connected to the middle surface of the octopus foot, and a buffer pad is fixedly connected to one side surface of the adjusting screw.

[0020] Through the above technical scheme, in order to facilitate the resetting of the octopus foot and realize the movement of the I-beam, when the adjusting screw is reset, the expanded octopus foot can be contracted and moved to the outside of the groove shell with the force of the resetting spring, thereby releasing the lock of the octopus foot. In order to limit the movement of the adjusting screw, after the adjusting screw moves, the movement of the adjusting screw is controlled by squeezing the buffer pad and the inner wall of the groove shell, and the ball can reduce the resistance of the octopus foot to open.

[0021] Preferably, the locking mechanism also includes an adjusting sleeve rotatably connected to the surface of the I-beam through a bearing, the inner surface of the adjusting sleeve is threadedly sleeved with the outer surface of the adjusting screw, the outer surfaces of the four adjusting sleeves on one side are fixedly sleeved with pulleys, the outer surfaces of the four pulleys are transmission-connected with transmission belts, and the transmission belt passes through the surface of the I-beam through the opened through holes.

[0022] Through the above technical scheme, four symmetrical adjusting screws are respectively provided on the two side surfaces of the I-beam. In order to drive the four adjusting screws on one side to rotate synchronously, the four pulleys are driven to rotate by the transmission belt, so that the adjusting sleeve is driven to rotate, thereby realizing the horizontal movement of the adjusting screw.

[0024] Through the above technical scheme, in order to realize the synchronous rotation of all the adjusting screws and ensure the horizontal locking state of the I-beam, the linkage block of the linkage pipe is inserted into the linkage groove of the adjusting screw, so that when the linkage pipe rotates, the two adjusting screws in front and behind are driven to rotate, and then under the transmission of the pulley and the transmission belt, the synchronous rotation of multiple adjusting pipe sleeves can be realized. In order to control the rotation of one of the linkage pipes, the transmission motor controls the rotation of the active bevel gear, and then drives the linkage pipe to rotate under the meshing of the driven bevel gear to realize the movement and adjustment of the adjusting screw.

[0025] Preferably, the locking mechanism also includes a connecting shaft that passes through the surface of the I-beam and is fixedly connected, and the outer surfaces at both ends of the connecting shaft are respectively fixedly connected with flat-plate adsorption manipulators, and the end face of the connecting shaft is fixedly connected to one side surface of the cross steel, and the side surface of the cross steel close to the I-beam is fixedly connected to the surface of the I-beam through a support rod.

[0026] Through the above technical scheme, the octopus foot locks the horizontal direction of the front and rear of the I-beam. In order to improve the stability of the I-beam and make the I-beam support the cross steel, it is necessary to support the I-beam in the left and right horizontal directions. Therefore, the flat adsorption manipulator is composed of a flat support frame and multiple vacuum suction cups. After the I-beam stops moving, the vacuum suction cups of the flat adsorption manipulator are adsorbed on the inner surface of the supporting beam steel, thereby improving the stability of the I-beam.

[0027] The beneficial effects of the present invention are:

[0028] 1.

During the adjustment process, the two rotating shafts rotate at the same time, driving the four climbing gears to rotate synchronously, so that the climbing gears climb on the outer surface of the rack rod, thereby realizing the height adjustment of the I-beam, so that the steel structure connection device can be adjusted as needed to adapt to different design requirements and construction conditions.

[0029] 2. By setting a locking mechanism, the climbing mechanism can be automatically locked. During the adjustment process, when the adjusting screw moves forward, the hinged eight-claw foot is gradually spread open, and the support foot abuts against the inner wall of the groove shell and the surface of the clamping plate, so that the eight-claw foot is restricted from moving, thereby achieving a locking effect. At the same time, after the I-beam stops moving, the vacuum suction cup of the flat adsorption manipulator is adsorbed on the inner surface of the supporting beam steel, thereby improving the stability of the I-beam, solving the technical problem that the existing steel structure connection device requires manual fixation of the final steel structure and increases the operation risk, while ensuring the reliability and stability of the connection.

DETAILED DESCRIPTION

[0043] The technical solutions in the embodiments of the present invention will be described clearly and completely 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, rather than all the embodiments.

[0044] Reference Figure 1-Figure 12 An adjustable steel structure connection device includes a supporting steel base 1, a supporting beam steel 2 with a cavity inside is fixedly connected to the upper surface of the steel base 1, sliding holes 3 are penetrated on both side surfaces of the supporting beam steel 2, and cross steels 4 for connecting steel columns are slidably clamped on the inner sides of the sliding holes 3 on both sides, a climbing mechanism 5 is arranged inside the supporting beam steel 2, and a locking mechanism 6 is arranged on the end face of the climbing mechanism 5.

[0045] Among them, Figure 2-4 As shown, the climbing mechanism 5 is connected to the cross steel 4, and the climbing mechanism 5 includes an I-beam 51 arranged inside the support beam steel 2. When the I-beam 51 moves linearly on the inner surface of the support beam steel 2, it drives the cross steel 4 to adjust its height.

[0046] like Figure 4 As shown, in order to guide the height adjustment of the I-beam 51, the climbing mechanism 5 also includes a rack rod 52 which is symmetrically distributed and fixedly connected to the inner surface of the support beam steel 2. The outer surface of the I-beam 51 is slidably connected to one side surface of the rack rod 52. The end faces of both ends of the I-beam 51 are limited by the symmetrical rack rod 52, so that the I-beam 51 can maintain movement on the vertical line. At the same time, the rack rod 52 serves as a climbing path for the I-beam 51.

[0047] like Figure 4As shown, in order to achieve the height adjustment of the cross steel 4 driven by the I-beam 51, thereby facilitating the connection between the cross steel 4 and the steel column, the climbing mechanism 5 also includes climbing gears 53 symmetrically distributed on the two side surfaces of the I-beam 51, and the climbing gears 53 are rotatably connected to the surface of the I-beam 51 through the rotating shaft 54. The climbing gears 53 are meshed with the rack rod 52, and the two rotating shafts 54 rotate simultaneously, driving the four climbing gears 53 to rotate synchronously, so that the climbing gears 53 climb on the outer surface of the rack rod 52, thereby achieving the height adjustment of the I-beam 51.

[0048] like Figure 3 As shown, in order to control the rotation of the four climbing gears 53 to realize the movement of the I-beam 51, the climbing mechanism 5 also includes a first pulley assembly 55 installed on the outer surface of one end of the two rotating shafts 54, wherein the outer surface of the other end of one of the rotating shafts 54 is fixedly sleeved with a transmission gear 56, and a reduction motor 57 is fixedly installed on one side surface of the I-beam 51, and the outer surface of the output shaft of the reduction motor 57 is fixedly connected with a driving gear 58 through a coupling, and the driving gear 58 is meshed with the transmission gear 56. When the reduction motor 57 controls the driving gear 58 to rotate, it can drive the transmission gear 56 to rotate, so that the transmission gear 56 drives one of the rotating shafts 54 to rotate, and then under the transmission of the first pulley assembly 55, the other rotating shaft 54 ​​can be controlled to rotate, so that the four climbing gears 53 climb on the outer surface of the rack rod 52.

[0049] By setting up the climbing mechanism 5, the height of the cross steel 4 connected to the steel column can be adjusted, so that the steel structure connection device can meet the position adjustment. During the adjustment process, the two rotating shafts 54 rotate simultaneously, driving the four climbing gears 53 to rotate synchronously, so that the climbing gears 53 climb on the outer surface of the rack rod 52, thereby realizing the height adjustment of the I-beam 51, so that the steel structure connection device can be adjusted as needed to adapt to different design requirements and construction conditions.

[0050] Among them, Figure 5-12 As shown, the locking mechanism 6 is activated after the climbing mechanism 5 completes the adjustment, and the locking mechanism 6 includes an octopus foot 61, which is connected to the support beam steel 2 after the end surface of the I-beam 51 is opened, thereby locking the position of the I-beam 51.

[0051] like Figure 4-5As shown, in order to fix the position of the I-beam 51 after movement, the locking mechanism 6 also includes an installation cavity 62 opened inside the two ends of the support beam steel 2, and the inner surface of the support beam steel 2 is provided with a guide groove 63 connected to the interior of the installation cavity 62. The two end surfaces of the I-beam 51 are symmetrically distributed and slidably inserted with adjusting screws 64. When the I-beam 51 moves, the front end of the adjusting screw 64 moves on the inner wall of the guide groove 63. When the I-beam 51 stops moving, the adjusting screw 64 extends forward to the interior of the installation cavity 62 and engages with the interior of the cavity to lock the I-beam 51.

[0052] like Figure 9-10 As shown, in order to achieve the effect of locking the I-beam 51 when the adjusting screw 64 is extended, the locking mechanism 6 also includes a groove shell 65 fixedly connected to the inner wall of the installation cavity 62, and the inner wall of the groove shell 65 is symmetrically distributed and fixedly connected with a clamping plate 66, and the octopus feet 61 are distributed in a ring array and hingedly installed on the free end face of the adjusting screw 64, and the outer surface of the octopus feet 61 is slidingly connected to the inner wall of the groove shell 65 and the surface of the clamping plate 66 respectively. When the adjusting screw 64 moves forward, the hinged octopus feet 61 are gradually spread open, and the support feet abut against the inner wall of the groove shell 65 and the surface of the clamping plate 66, so that the octopus feet 61 are restricted from moving, thereby achieving the locking effect.

[0053] like Figure 8 As shown, in order to facilitate the resetting of the octopus foot 61 and realize the movement of the I-beam 51, a ball 67 is installed on the free end face of the octopus foot 61, and a reset spring 68 is fixedly connected to the middle surface of the octopus foot 61. When the adjusting screw 64 is reset, the expanded octopus foot 61 can be contracted and moved to the outside of the groove shell 65 with the force of the reset spring 68, thereby releasing the lock of the octopus foot 61. The ball 67 can reduce the resistance of the expansion of the octopus foot 61. In order to limit the movement of the adjusting screw 64, a buffer pad 69 is fixedly connected to the surface of one side of the adjusting screw 64. After the adjusting screw 64 moves, the movement of the adjusting screw 64 is controlled by squeezing the buffer pad 69 with the inner wall of the groove shell 65.

[0054] like Figure 5-6 As shown, four symmetrical adjusting screws 64 are respectively provided on the two side surfaces of the I-beam 51. In order to drive the four adjusting screws 64 on one side to rotate synchronously, the locking mechanism 6 also includes an adjusting sleeve 70 rotatably connected to the surface of the I-beam 51 through a bearing. The inner surface of the adjusting sleeve 70 is threadedly sleeved with the outer surface of the adjusting screw 64. The outer surfaces of the four adjusting sleeves 70 on one side are fixedly sleeved with pulleys 71. The outer surfaces of the four pulleys 71 are transmission-connected with transmission belts 72. The transmission belt 72 penetrates the surface of the I-beam 51 through the through holes provided. The four pulleys 71 are driven to rotate through the transmission belt 72, so that the adjusting sleeve 70 is driven to rotate, thereby realizing the horizontal movement of the adjusting screw 64.

[0055] like Figure 6-7 As shown, in order to realize the synchronous rotation of all the adjusting screws 64 and ensure the horizontal locking state of the I-beam 51, the locking mechanism 6 also includes a linkage tube 73 movably sleeved on the outer surfaces of the two adjusting screws 64, the inner side wall of the linkage tube 73 is symmetrically provided with linkage blocks 74, the outer surface of the adjusting screws 64 is symmetrically provided with linkage grooves 75, the outer surface of the linkage block 74 is slidably engaged with the inner wall of the linkage groove 75, the linkage block 74 of the linkage tube 73 is inserted into the linkage groove 75 of the adjusting screw 64, so that when the linkage tube 73 rotates, the two adjusting screws 64, one in front and one in the back, are driven to rotate, and then the pulley 7 Under the transmission of the transmission belt 72, the synchronous rotation of multiple adjustment tube sleeves 70 can be realized. In order to control the rotation of one of the linkage tubes 73, a driven bevel gear 76 is fixedly sleeved on the middle outer surface of the linkage tube 73, and a transmission motor 77 is fixedly connected to the surface of the I-beam 51. The outer surface of the output shaft of the transmission motor 77 is fixedly connected to a driving bevel gear 78 through a coupling. The driving bevel gear 78 is meshed with the driven bevel gear 76. The transmission motor 77 controls the driving bevel gear 78 to rotate, and then drives the linkage tube 73 to rotate under the meshing of the driven bevel gear 76 to realize the movement and adjustment of the adjusting screw 64.

[0056] like Figure 11-12 As shown, the octopus foot 61 locks the horizontal direction of the front and rear of the I-beam 51. In order to improve the stability of the I-beam 51 and make the I-beam 51 support the cross steel 4, the locking mechanism 6 also includes a connecting shaft 79 that passes through the surface of the I-beam 51 and is fixedly connected. The outer surfaces of both ends of the connecting shaft 79 are respectively fixedly connected with a flat adsorption manipulator 80. The end face of the connecting shaft 79 is fixedly connected to the side surface of the cross steel 4. The side surface of the cross steel 4 close to the I-beam 51 is fixedly connected to the surface of the I-beam 51 through a support rod. The flat adsorption manipulator 80 is composed of a flat support frame and a plurality of vacuum suction cups. After the I-beam 51 stops moving, the vacuum suction cup of the flat adsorption manipulator 80 is adsorbed on the inner surface of the support beam steel 2, thereby improving the stability of the I-beam 51.

[0057] By setting up a locking mechanism 6, the climbing mechanism 5 can be automatically locked. During the adjustment process, when the adjusting screw 64 moves forward, the hinged octopus foot 61 is gradually spread open, and the support foot abuts against the inner wall of the groove shell 65 and the surface of the clamping plate 66, so that the octopus foot 61 is restricted from moving, thereby achieving a locking effect. At the same time, after the I-beam 51 stops moving, the vacuum suction cup of the flat adsorption robot 80 is adsorbed on the inner surface of the support beam steel 2, thereby improving the stability of the I-beam 51, solving the technical problem that the existing steel structure connection device requires manual fixation of the final steel structure and increases the operation risk, while ensuring the reliability and stability of the connection.

[0058] Working principle: Figure 1-12 As shown, in a specific embodiment of the present invention, the connection of the steel structure can be achieved by connecting the steel column with the outer surface of the cross steel 4. When the height of the steel column needs to be adjusted, the driving gear 58 is controlled to rotate by the reduction motor 57, which can drive the transmission gear 56 to rotate, so that the transmission gear 56 drives one of the rotating shafts 54 to rotate, and then the other rotating shaft 54 ​​can be controlled to rotate under the transmission of the first pulley assembly 55, so that the four climbing gears 53 climb on the outer surface of the rack rod 52;

[0059] At this time, the outer surface of the I-beam 51 moves along the side of the rack rod 52, thereby driving the cross steel 4 to move on the inner wall of the sliding hole 3 of the support beam steel 2, thereby realizing the height adjustment of the steel column, and when the I-beam 51 moves, the front end of the adjusting screw 64 moves on the inner wall of the guide groove 63;

[0060] When the I-beam 51 stops moving, the transmission motor 77 controls the driving bevel gear 78 to rotate, and then drives one of the linkage tubes 73 to rotate under the meshing of the driven bevel gear 76. Since the linkage block 74 of the linkage tube 73 is inserted into the linkage groove 75 of the adjusting screw 64, the linkage tube 73 drives the two adjusting screws 64 to rotate one in front and one behind when rotating, and then drives the adjusting tube sleeve 70 to rotate under the transmission of the pulley 71 and the transmission belt 72, so that multiple adjusting screws 64 move synchronously;

[0061] When the adjusting screw 64 moves forward, the hinged octagonal foot 61 is gradually spread open, and the supporting feet abut against the inner wall of the groove shell 65 and the surface of the clamping plate 66, so that the octagonal foot 61 is restricted from moving, thereby achieving a locking effect. The octagonal foot 61 locks the horizontal direction of the front and rear of the I-beam 51, and after the I-beam 51 stops moving, the vacuum suction cup of the flat adsorption robot 80 is adsorbed on the inner surface of the support beam steel 2, thereby improving the stability of the I-beam 51 and ensuring the reliability of the steel structure connection device.

[0062] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
