Description

Technical Field

[0001] The utility model relates to the technical field of construction, in particular to a steel structure connection device which is easy to maintain. Background Art

[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates, and adopts silanization, pure manganese phosphating, water washing and drying, galvanizing and other rust removal and rust prevention processes. Because of its light weight and simple construction, it is widely used in large factories, venues, super high-rise buildings, bridges and other fields.

[0003] Existing steel structures are often connected by bolts or rivets. However, in this connection process, in order to ensure that the connection parts are accurately positioned at the target position, workers often need to use additional fixing methods. This includes using lines to mark the connection points so as to maintain the correct position and angle of the connection in actual operation. When connecting steel structures, multiple workers are required to participate in the operation at the same time, which increases the cost of using workers. At the same time, due to the lack of coordination between multiple workers during operation, it is easy to cause the steel structure to shift. This shift will affect the final connection, so the steel structure needs to be realigned, which reduces the connection efficiency of the steel structure. Therefore, a steel structure connection device that is easy to maintain is proposed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1-Figure 3 The utility model provides an embodiment: a steel structure connection device that is easy to maintain, including two lower shells 1 and a base 13. The two lower shells 1 are located above the base 13. An upper shell 2 is arranged on the top of the lower shell 1. The outer sides of the lower shell 1 and the upper shell 2 are fixedly connected with a connecting plate 3. The lower shell 1 and the upper shell 2 can be connected by bolts or screws through the connecting plate 3. When the internal parts of the lower shell 1 and the upper shell 2 need to be maintained, the lower shell 1 and the upper shell 2 can be quickly dismantled and the internal parts can be maintained.

[0032] Reference Figure 1-Figure 3 The middle part of the upper shell 2 is rotatably connected with a connecting rod 4, one end of the connecting rod 4 is fixedly connected with a worm 5, the other end of the worm 5 is fixedly connected with a spring 6, the other end of the spring 6 is fixedly connected to the inside of the upper shell 2, a worm wheel 7 is rotatably connected between the lower shell 1 and the upper shell 2, the worm wheel 7 and the worm 5 are meshed, and a turntable 8 is fixedly connected to the adjacent sides of the two worm wheels 7, the middle part of the turntable 8 is rotatably connected with four arc plates 9, the other side of the arc plate 9 is rotatably connected with a limit block 10, and the four limit blocks 10 are slidably connected to the middle parts of the lower shell 1 and the upper shell 2 respectively.

[0033] Reference Figure 1-Figure 3By rotating the connecting rod 4, the clockwork spring 6 can be twisted and compressed, and at the same time, the worm 5 and the worm wheel 7 can be driven to rotate simultaneously when the connecting rod 4 rotates, and then the worm wheel 7 can drive the turntable 8 to rotate. At this time, the four limit blocks 10 can drive the four clamping plates 11 to move away from each other at the same time through the arc plate 9. By placing one side of the steel structure between the four clamping plates 11, after the steel structure is placed, the connecting rod 4 can be loosened and the connecting rod 4 can be rotated in the opposite direction under the action of the clockwork spring 6, so that the four clamping plates 11 can be brought close to each other. At this time, the steel structure can be clamped and fixed, and the steel structure can be positioned between the lower shell 1 and the upper shell 2, so that the steel structure can be kept in a parallel position with the connecting piece, and at the same time, the connection of the steel structure can be facilitated, thereby improving the connection efficiency of the steel structure and reducing the cost of using workers.

[0034] Reference Figure 1-Figure 3 The limit block 10 is fixedly connected to a clamping plate 11 on one side away from the arc plate 9. Two limit grooves 23 are provided on the outer sides of the lower shell 1 and the upper shell 2. The limit block 10 is slidably connected to the middle of the limit groove 23. The limit block 10 can be limited by the limit groove 23 to prevent the limit block 10 from tilting during the movement, so that the limit block 10 can only drive the clamping plate 11 to move in parallel, thereby improving the positioning effect of the clamping plate 11. A rubber pad 12 is fixedly connected to the outer side of the clamping plate 11. The rubber pad 12 can further improve the stability of the clamping and prevent the possibility of the steel structure falling off. A displacement component is arranged inside the base 13.

[0035] Reference Figure 1 and Figure 4 The displacement assembly includes a bidirectional screw rod 14, which is rotatably connected to the inside of the base 13. The outer periphery of the bidirectional screw rod 14 is threadedly connected to two nut seats 15. The two lower shells 1 are respectively located above the two nut seats 15. By rotating the bidirectional screw rod 14, the nut seat 15 can drive the two lower shells 1 to approach each other, and then the steel structure can be connected to the connecting piece, which can reduce the labor intensity of employees. A connecting assembly is arranged between the lower shell 1 and the nut seat 15.

[0036] Reference Figure 2 and Figure 5The connection assembly includes a positioning block 16, which is fixedly connected to the bottom of the lower shell 1. The top of the nut seat 15 is fixedly connected with a mounting plate 17. The positioning block 16 and the mounting plate 17 are plugged together. A positioning groove 24 is provided on the top of the mounting plate 17. The positioning block 16 and the positioning groove 24 are plugged together. The positioning block 16 can be restricted by the positioning groove 24, thereby accelerating the alignment speed of the lower shell 1 and the mounting plate 17, and improving the installation speed of the lower shell 1. A compression spring 18 is fixedly connected inside the mounting plate 17, and a clamping block 19 is fixedly connected to the other end of the compression spring 18. The clamping block 19 contacts the positioning block 16. The positioning block 16 is provided with a card slot 20, and the card block 19 and the card slot 20 are plugged together. When the positioning block 16 enters the positioning slot 24, the positioning block 16 will contact the card block 19. At this time, the positioning block 16 will squeeze the card block 19 and make the card block 19 move. When the card block 19 moves, the compression spring 18 will be compressed. At the same time, the card block 19 will be received into the inside of the mounting plate 17. At this time, the positioning block 16 can be completely inserted into the mounting plate 17. When the card slot 20 moves to a position parallel to the card block 19 and the card block 19 is not squeezed by external force, the card block 19 can be bounced into the card slot 20 by the compression spring 18, so that the installation and fixation of the lower shell 1 can be facilitated.

[0037] Reference Figure 5 The mounting plate 17 is internally slidably connected with a partition, which is fixedly connected between the compression spring 18 and the block 19. The partition can prevent the block 19 from shifting during movement, and can prevent the compression spring 18 from being deformed and damaged due to the tilting and squeezing of the block 19, thereby increasing the service life of the compression spring 18. The middle part of the mounting plate 17 is rotatably connected with a disassembly component.

[0038] Reference Figure 5 The disassembly assembly includes a rotating rod 21, which is rotatably connected to the middle part of the mounting plate 17. A pull rope 22 is fixedly connected to the outer side of the rotating rod 21. The other end of the pull rope 22 is fixedly connected to the side of the card block 19 close to the compression spring 18. The pull rope 22 can be rolled up by rotating the rotating rod 21. At this time, the card block 19 can be pulled out from the middle part of the card slot 20 by the rolled-up pull rope 22, so that the lower shell 1 can be easily removed, which can improve the assembly and disassembly efficiency of the lower shell 1. At the same time, the lower shell 1 can be quickly replaced when maintenance is needed, which is convenient for maintenance of the lower shell 1. At the same time, the connection work of the steel structure is not affected while the lower shell 1 is maintained.

[0039] Working principle: By rotating the connecting rod 4, the worm 5 can drive the worm wheel 7 and the turntable 8 to rotate simultaneously, and the limit block 10 can drive the four clamping plates 11 to move away from each other through the arc plate 9. At this time, the steel structure can be placed between the four clamping plates 11. At this time, by loosening the connecting rod 4 and under the action of the spring 6, the connecting rod 4 can be rotated in the opposite direction, so that the clamping plates 11 can clamp the steel structure to be connected and position it to the center position. At this time, the positioned steel structure can be moved by rotating the bidirectional screw rod 14, so that the steel structure can be easily aligned with the connecting component;

[0040] Among them, by inserting the positioning block 16 into the mounting plate 17, the block 19 will compress the compression spring 18 when the positioning block 16 enters. When the slot 20 moves to the original position of the block 19, the block 19 can be bounced into the slot 20 through the compression spring 18, so that the lower shell 1 and the nut seat 15 can be conveniently connected. The pull rope 22 can be reeled in by rotating the rotating rod 21. At this time, the block 19 and the slot 20 can be separated, and then the lower shell 1 and the nut seat 15 can be conveniently separated, so that the lower shell 1 can be easily maintained or replaced.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
