Description

Technical Field

[0001] The present invention relates to the technical field of steel structure connection, and more specifically, to a quick connection mechanism for steel structure support steel plates with a self-locking function. Background Art

[0002] The basic components of a steel structure are connected by steel plates, sections, etc., such as beams, columns, frames, etc. After being transported to the construction site, they are assembled into an integral structure through installation. The main quick connection methods for steel structure support steel plates mainly include bolt connection and welding connection. In practical applications, the appropriate connection method should be selected comprehensively considering factors such as specific requirements, structural types, and load conditions to ensure the safety and reliability of the connection of steel structure support steel plates.

[0003] Since sufficient strength, stiffness, and ductility should be provided at the connection part during the force transmission process of the steel plate, connections play a very important role in steel structures, and the connected parts should be kept in the correct position to meet the force transmission and use requirements.

[0004] In the prior art, in order to keep the connecting piece in the correct position, positioning tools are used to perform preliminary positioning on the main beam plate and the secondary beam plate. Before the preliminary positioning, it is necessary to perform horizontal calibration on the height and front-back position of the secondary beam plate, and level the angle of the secondary beam plate. The adjustment process takes a long time and the installation efficiency is low. Summary of the Invention

[0005] The quick connection mechanism for steel structure support steel plates with a self-locking function provided by the present invention aims to solve the problem that in the existing quick connection mechanism for steel structure support steel plates, before the preliminary positioning, it is necessary to perform horizontal calibration on the height and front-back position of the secondary beam plate, and level the angle of the secondary beam plate. The adjustment process takes a long time and the installation efficiency is low.

[0006] To achieve the above object, the present invention provides the following technical solution: a quick connection mechanism for a steel structure support steel plate with a self-locking function, including a moving seat installed between the main beam and the first secondary beam. The bottom of the moving seat is fixedly provided with a structure that slides inside the main beam groove of the main beam. A second secondary beam is arranged on the side of the main beam away from the first secondary beam. Connecting plates are welded to the connecting ends of the first secondary beam and the second secondary beam. A supporting mechanism is installed on the moving seat. The supporting mechanism includes a first supporting seat and a second supporting seat, and the first supporting seat and the second supporting seat are respectively arranged on both sides of the moving seat. Both the first supporting seat and the second supporting seat include a top plate, and a driving component is installed at one end of the bottom of the top plate. A locking component is installed at the output end of the driving component. The locking component includes a first locking block and a second locking block, and both the first locking block and the second locking block slide inside the secondary beam groove of the first secondary beam. When the first locking block and the second locking block are located inside the secondary beam groove, the first secondary beam is in a horizontal state. The driving component drives the first locking block and the second locking block to approach or move away from each other. Installation blocks are installed on both the first locking block and the second locking block. An installation handle is detachably installed on the installation block. A locking piece is installed on the installation handle, and the locking piece is used to support the connection between the main beam and the connecting plate.

[0007] Implementation method: First, place it inside the main beam groove, then push the moving seat along the main beam groove to the installation positions of the first secondary beam and the second secondary beam. Install the first secondary beam from bottom to top so that the first locking block and the second locking block are inserted into the inside of the secondary beam groove. At this time, the first secondary beam is in a horizontal state. Then, drive the first secondary beam to move along the axial direction of the main beam through the moving seat, quickly adjust the connection position between the main beam and the first secondary beam. Finally, drive the first locking block and the second locking block to approach each other through the driving component, and temporarily support the connecting plate at the installation position through the locking piece on the installation handle, facilitating subsequent welding or bolt connection.

[0008] In a preferred implementation method, the driving component includes an output shaft. A positive thread is provided on the outer periphery of one end of the output shaft, and the positive thread is in transmission connection with the first locking block. A reverse thread is provided on the outer periphery of the end of the output shaft away from the positive thread, and the reverse thread is in transmission connection with the second locking block.

[0009] In a preferred implementation method, the moving seat includes a base. An installation platform is provided inside the base. A driving motor is installed on the installation platform, and the output end of the driving motor is fixedly connected to the output shaft.

[0010] In a preferred implementation method, a support frame is installed on the installation platform. A fixing block is fixedly provided at one end of the bottom of the top plate, and the output shaft passes through the inside of the support frame and the fixing block in sequence.

[0011] Implementation method: Drive the output shaft to rotate through the driving motor. Through the positive thread and the reverse thread on the output shaft, the first locking block and the second locking block approach and clamp for positioning, or the first locking block and the second locking block move away from each other to release the positioning. The limiting disks corresponding to both ends of the support frame on the output shaft limit the axial movement of the output shaft.

[0012] In a preferred embodiment, a linear actuator is installed inside the base. The linear actuator is used to drive the mounting table to move vertically. Slots are formed on both sides of the base, and the output shaft penetrates through the inside of the slots.

[0013] In a preferred embodiment, a cover plate is installed on the top of the base, and a partition is installed inside the base, and the partition is located above the mounting table.

[0014] In a preferred embodiment, a mounting rack is installed on the top plate. The mounting rack includes a long carrier plate. A guiding groove is formed on the top of the top plate. The long carrier plate is slidably disposed inside the guiding groove. A limiting plate is fixedly provided on the long carrier plate. The limiting plate is detachably connected to the top plate by screws. Short carrier plates are connected to both ends of the long carrier plate, and the short carrier plates are positioned and connected to the mounting table.

[0015] Embodiment: First, adjust the positions of the first support seat and the second support seat on both sides of the base. By moving the top plate along the axial direction of the main beam, adjust the front and rear positions. After adjustment, fix the limiting plate on the top plate. Drive the mounting table to move up and down through the linear actuator, and drive the top plate to move up and down through the short carrier plate to adjust the height position of the top plate.

[0016] In a preferred embodiment, when positioning blocks are welded on both the inner side wall of the main beam groove and the connecting plate, the locking member is a first clamping plate. Two sets of first clamping plates are arranged oppositely, and the two sets of first clamping plates are respectively connected to the first locking block and the second locking block. Slots are formed on the opposite sides of the two sets of first clamping plates.

[0017] In a preferred embodiment, when positioning holes are formed on both the side of the main beam and the connecting plate, the locking member is a sleeve. The first locking block installs the sleeve through the corresponding mounting block and mounting handle. The second locking block installs a pin through the corresponding mounting block and mounting handle. The pin penetrates through the positioning hole, and one end of the pin is disposed inside the sleeve.

[0018] In a preferred embodiment, when the main beam and the connecting plate have an eaves edge structure, the locking member is a second clamping plate. An adaptation groove is formed on one side of the second clamping plate, and the shape of the adaptation groove is adapted to the shape of the eaves edge structure.

[0019] Embodiments: According to the positioning methods of the main beam and the connecting plate, select the corresponding locking parts. Method 1: The inner side wall of the main beam groove and the outer side of the connecting plate are positioned by positioning blocks. At this time, the main beam and the connecting plate are fixed by welding. The positioning blocks are clamped by the clamping grooves of the first clamping plate to temporarily lock the main beam and the connecting plate, facilitating accurate welding. Method 2: When the main beam and the connecting plate are positioned by positioning holes and bolts, the locking parts are replaced with sleeves and pin columns. The pin columns pass through the positioning holes and are butt-jointed with the sleeves to achieve a temporary locking effect. The sleeves and pin columns temporarily lock at least two positioning holes, and bolts are finally installed in these two positioning holes when the support mechanism moves to the next working station. Method 3: The main beam and the connecting plate adopt a bridging connection method, that is, after the main beam and the connecting plate are spliced, bridge plates are added at the ends. The bridge plates are respectively connected to the main beam and the connecting plate, and the connection methods are bolt connection or welding. The main beam and the connecting plate are butt-jointed to form a T-shaped structure, and the matching grooves between two groups of second clamping plates form a T-shaped opening to lock the T-shaped structure.

[0020] The beneficial effects of the present invention are as follows: The present invention temporarily supports the connecting plate at the installation position through the locking parts on the installation handle, facilitating subsequent welding or bolt connection. As a whole, it is convenient to support the first secondary beam on the side of the main beam to quickly adjust the position in a horizontal state without the need for horizontal calibration, saving installation time and ensuring installation accuracy.

[0021] The present invention adjusts the front and rear positions by moving the top plate along the axial direction of the main beam, drives the installation table to move up and down through the linear actuator, and drives the top plate to move up and down through the short load plate to adjust the height position of the top plate, increasing the flexibility of use.

[0022] The present invention can be applied to multiple installation scenarios by selecting the corresponding locking parts according to the positioning methods of the main beam and the connecting plate, as well as the welding or high-strength bolt connection methods. Description of the Drawings

It is necessary to point out here that the following detailed implementation manners are only used to further illustrate the present application and cannot be understood as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application according to the above application content.

[0033] Refer to the attached drawings of the specification Figures 1 to 4, A quick connection mechanism for a steel structure support steel plate with a self-locking function, including a moving seat 3 installed between the main beam 1 and the first secondary beam 2. A [7] is fixedly provided at the bottom of the moving seat 3, and the [7] slides inside the main beam groove 11 of the main beam 1. A second secondary beam 23 is provided on the side of the main beam 1 away from the first secondary beam 2. Connecting plates 22 are welded to the connecting ends of the first secondary beam 2 and the second secondary beam 23; a supporting mechanism 4 is installed on the moving seat 3. The supporting mechanism 4 includes a first supporting seat 41 and a second supporting seat 42, and the first supporting seat 41 and the second supporting seat 42 are respectively arranged on both sides of the moving seat 3. The first supporting seat 41 and the second supporting seat 42 both include a top plate 421, and a driving component is installed at one end of the bottom of the top plate 421; a locking component 5 is installed at the output end of the driving component. The locking component 5 includes a first locking block 51 and a second locking block 52, and the first locking block 51 and the second locking block 52 both slide inside the secondary beam groove 21 of the first secondary beam 2. When the first locking block 51 and the second locking block 52 are located inside the secondary beam groove 21, the first secondary beam 2 is in a horizontal state, and the driving component drives the first locking block 51 and the second locking block 52 to approach or move away from each other; mounting blocks 53 are installed on both the first locking block 51 and the second locking block 52, and a mounting handle 54 is detachably installed on the mounting block 53. A locking member is installed on the mounting handle 54, and the locking member is used to support the connection between the main beam 1 and the connecting plate 22.

[0034] It should be noted that the bottom of the [7] is adapted to the shape of the main beam groove 11. Both the first supporting seat 41 and the second supporting seat 42 are located at the connection between the main beam 1 and the first secondary beam 2. The top plate 421 is slidably connected to the first locking block 51 and the second locking block 52 respectively, and the first locking block 51 and the second locking block 52 are respectively located on both sides of the connection between the main beam 1 and the connecting plate 22.

[0035] In this embodiment, the implementation scenario is as follows: First, put the [7] into the main beam groove 11, then push the moving seat 3 along the main beam groove 11 to the installation positions of the first secondary beam 2 and the second secondary beam 23, install the first secondary beam 2 from bottom to top, so that the first locking block 51 and the second locking block 52 are caught inside the secondary beam groove 21. At this time, the first secondary beam 2 is in a horizontal state. Then, drive the first secondary beam 2 to move axially along the main beam 1 through the moving seat 3, quickly adjust the connection position between the main beam 1 and the first secondary beam 2. Finally, drive the first locking block 51 and the second locking block 52 to approach each other through the driving component, and temporarily support the connecting plate 22 at the installation position through the locking member on the mounting handle 54, which is convenient for subsequent welding or bolt connection. As a whole, it is convenient to support the first secondary beam 2 on the side of the main beam 1 to quickly adjust the position in a horizontal state, without the need for horizontal calibration, saving installation time and ensuring installation accuracy.

[0036] Refer to the attached drawings of the specification Figure 3 and Figure 4, the driving assembly includes an output shaft 314. A right-handed thread 3141 is provided on the outer periphery of one end of the output shaft 314, and the right-handed thread 3141 is in driving connection with the first locking block 51. An opposite-handed thread 3142 is provided on the outer periphery of the end of the output shaft 314 away from the right-handed thread 3141, and the opposite-handed thread 3142 is in driving connection with the second locking block 52.

[0037] It should be noted that the thread directions of the right-handed thread 3141 and the opposite-handed thread 3142 are opposite, and the driving connection between the right-handed thread 3141 and the first locking block 51 is a threaded connection.

[0038] Furthermore, the moving seat 3 includes a base 31. An installation platform 311 is provided inside the base 31. A driving motor 312 is installed on the installation platform 311, and the output end of the driving motor 312 is fixedly connected to the output shaft 314.

[0039] It should be noted that two rows of driving motors 312 are provided and their directions are opposite, which is convenient for driving the output shafts 314 on both sides.

[0040] Furthermore, a support frame 313 is installed on the installation platform 311. A fixing block 422 is fixedly provided at one end of the bottom of the top plate 421, and the output shaft 314 passes through the inside of the support frame 313 and the fixing block 422 in sequence.

[0041] It should be noted that the support frame 313 is a sleeve member. In order to reduce the influence of the axial tension of the output shaft 314 on the driving motor 312, limit discs are fixedly installed at both ends of the output shaft 314 corresponding to the support frame 313.

[0042] In this embodiment, the implementation scenario is specifically as follows: The driving motor 312 drives the output shaft 314 to rotate. Through the right-handed thread 3141 and the opposite-handed thread 3142 on the output shaft 314, the first locking block 51 and the second locking block 52 are moved closer to clamp and position each other, or the first locking block 51 and the second locking block 52 are moved away from each other to release the positioning. The limit discs at both ends of the output shaft 314 corresponding to the support frame 313 limit the axial movement of the output shaft 314, avoiding damage to the driving motor 312 caused by axial tension.

[0043] Refer to the attached instructions Figures 2 to 5 , a linear actuator 316 is installed inside the base 31. The linear actuator 316 is used to drive the installation platform 311 to move vertically. Slots 315 are opened on both sides of the base 31, and the output shaft 314 passes through the inside of the slots 315.

[0044] It should be noted that the installation platform 311 bears the driving motor 312 and the support frame 313 to move up and down, and the slots 315 are adapted to the up and down movement of the output shaft 314.

[0045] Furthermore, a cover plate 32 is installed at the top of the base 31, and a partition plate 317 is installed inside the base 31, and the partition plate 317 is located above the mounting table 311.

[0046] It should be noted that the cover plate 32 and the base 31 are detachably connected by screws, and components such as a controller and a power supply are installed on the partition plate 317.

[0047] Furthermore, a mounting frame 6 is installed on the top plate 421. The mounting frame 6 includes a long carrier plate 61. A guiding groove 423 is formed at the top of the top plate 421. The long carrier plate 61 is slidably arranged inside the guiding groove 423. A limiting plate 63 is fixedly arranged on the long carrier plate 61. The limiting plate 63 and the top plate 421 are detachably connected by screws. Both ends of the long carrier plate 61 are connected with short carrier plates 62, and the short carrier plates 62 are positioned and connected with the mounting table 311.

[0048] It should be noted that the sliding connection between the guiding groove 423 and the long carrier plate 61 plays a guiding role, facilitating the adjustment of the position of the top plate 421 along the axial direction of the main beam 1, and the connection between the short carrier plates 62 and the mounting table 311 facilitates the vertical adjustment of the position of the top plate 421.

[0049] In this embodiment, the implementation scenario is specifically as follows: Before use, first adjust the positions of the first support base 41 and the second support base 42 on both sides of the base 31. By moving the top plate 421 along the axial direction of the main beam 1, adjust the front and rear positions. After adjustment, fix the limiting plate 63 on the top plate 421. Drive the mounting table 311 to move up and down through the linear actuator 316, and drive the top plate 421 to move up and down through the short carrier plates 62 to adjust the height position of the top plate 421, increasing the flexibility of use.

[0050] Refer to the attached Figures 4 to 8 When positioning blocks are welded on both the inner side wall of the main beam groove 11 and the connecting plate 22, the locking member is the first clamping plate 55. There are two groups of the first clamping plates 55 arranged oppositely, and the two groups of the first clamping plates 55 are respectively connected with the first locking block 51 and the second locking block 52. Grooves are formed on the opposite sides of the two groups of the first clamping plates 55.

[0051] It should be noted that in order to facilitate calibration and positioning, positioning blocks are welded on the inner side wall of the main beam groove 11 and the connecting plate 22. The shape of the positioning block is adapted to the shape of the groove, such as when the positioning block is triangular, the groove is also triangular.

[0052] Furthermore, when positioning holes are formed on both the side of the main beam 1 and the connecting plate 22, the locking member is a sleeve 56. The first locking block 51 installs the sleeve 56 through the corresponding mounting block 53 and mounting handle 54. The second locking block 52 installs a pin 57 through the corresponding mounting block 53 and mounting handle 54. The pin 57 penetrates through the positioning hole, and one end of the pin 57 is arranged inside the sleeve 56.

[0053] It should be noted that when the main beam 1 and the connecting plate 22 are calibrated and positioned through the positioning holes, the locking member is replaced with a sleeve 56 and a pin 57.

[0054] Furthermore, when the main beam 1 and the connecting plate 22 have a eaves edge structure, the locking member is the second clamping plate 58. An adaptation groove 59 is formed on one side of the second clamping plate 58, and the shape of the adaptation groove 59 is adapted to the shape of the eaves edge structure.

[0055] It should be noted that when the main beam 1 and the connecting plate 22 are butted to form a T shape, the adaptation grooves 59 between the two groups of second clamping plates 58 form a T-shaped opening.

[0056] In this embodiment, the implementation scenario is specifically as follows: According to the positioning method of the main beam 1 and the connecting plate 22, the corresponding locking member is selected. Method 1: The inner side wall of the main beam groove 11 and the outer side of the connecting plate 22 are positioned by positioning blocks. At this time, the main beam 1 and the connecting plate 22 are fixed by welding. The main beam 1 and the connecting plate 22 are temporarily locked by clamping the positioning blocks with the clamping grooves of the first clamping plate 55, which is convenient for accurate welding. Method 2: When the main beam 1 and the connecting plate 22 are positioned by positioning holes and bolts, the locking member is replaced with a sleeve 56 and a pin 57. The pin 57 passes through the positioning hole and is butted with the sleeve 56 to achieve a temporary locking effect. The sleeve 56 and the pin 57 temporarily lock at least two positioning holes, and bolts are finally installed in these two positioning holes when the supporting mechanism 4 moves to the next working position. Method 3: The main beam 1 and the connecting plate 22 adopt a bridging connection method, that is, after the main beam 1 and the connecting plate 22 are spliced, a bridge plate is installed at the end. The bridge plate is respectively connected to the main beam 1 and the connecting plate 22, and the connection method is bolt connection or welding. The main beam 1 and the connecting plate 22 are butted to form a T-shaped structure, and the adaptation grooves 59 between the two groups of second clamping plates 58 form a T-shaped opening to lock the T-shaped structure, which can be applied to multiple installation scenarios.

[0057] Working principle: First, place 7 inside the main beam groove 11, and then push the moving seat 3 along the main beam groove 11 to the installation positions of the first auxiliary beam 2 and the second auxiliary beam 23. Install the first auxiliary beam 2 from bottom to top, so that the first locking block 51 and the second locking block 52 are clamped into the inside of the auxiliary beam groove 21.

[0058] Then drive the first auxiliary beam 2 to move axially along the main beam 1 through the moving seat 3, and quickly adjust the connection position between the main beam 1 and the first auxiliary beam 2.

[0059] Next, drive the first locking block 51 and the second locking block 52 to approach each other through the driving assembly, and temporarily support the connecting plate 22 at the installation position through the locking member on the installation handle 54.

[0060] Finally, weld or bolt-connect the main beam 1 and the first auxiliary beam 2.

[0061] The above embodiments merely illustrate several implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several variations and improvements can still be made, and these all fall within the protection scope of the present invention.
