[0001] The present invention relates to the technical field of bolt installation tools, and specifically relates to a sliding high-altitude bolt installation device for steel structures and an installation method thereof. Background Technique

[0002] A steel structure is a structure composed of steel materials and is one of the main building structure types. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of sections and steel plates.

[0003] In the prior art, when assembling a steel structure, bolts are required for fixing, and the tightening of the bolts requires workers to use corresponding wrenches to tighten.

[0004] However, at present, some steel structures are at a relatively high height. When workers are working at high altitudes, it is difficult to apply sufficient torque to the bolts, and the tightening force of the bolts is difficult to meet the connection requirements, resulting in poor connection strength between the steel structures and posing a great safety hazard.

A sliding block is movably inserted into the end of the limit sleeve. One end of the sliding block is fixedly connected to a pressing platform. A V-shaped groove is provided on the surface of the pressing platform. The V-shaped groove is buckled on the outside of the two pressure-bearing platforms and is located inside the card slot; and

[0009] A support rod. The support rod is horizontally slidably installed on the outside of the outer frame. An adjusting rod is slidably arranged at the upper end of the support rod. An inner hexagonal sleeve is provided at one end of the adjusting rod. A polygonal insertion rod for driving the adjusting rod to rotate is inserted into the other end of the adjusting rod. One end of the polygonal insertion rod is fixedly connected to a handle plate.

[0010] Preferably, a guide cylinder is provided at the upper end of the support rod, one end of the guide cylinder is rotatably connected to the upper end of the support rod, and the other end of the adjustment rod is movably plugged into the inner cavity of the guide cylinder.

[0014] Preferably, a limiting groove is provided on the surface of the limiting sleeve, the other end of the sliding block is fixedly connected to the limiting block, the limiting block passes through the limiting groove and is slidably connected thereto, and the other end face of the sliding block is fixedly connected to a compression spring located in the inner cavity of the limiting sleeve.

[0015] Preferably, the lower end of the support rod is fixedly connected to a 匚-shaped clamping plate, and the 匚-shaped clamping plate is buckled on the outside of the first 匚-shaped frame and slidably connected thereto, and the inner side wall of the 匚-shaped clamping plate is fixedly connected to a dovetail slider, and the outer side wall of the first 匚-shaped frame is provided with a dovetail groove, and the dovetail slider is located in the inner cavity of the dovetail groove and is adapted thereto.

Then splice two first U-shaped frames together and hold them outside the inner frame, ensuring that the pressing platform just fits into the bottom of the slot of the clamping groove located outside the bearing platform under the thrust of the compression spring. At this time, the inner wall of the V-shaped groove presses against the bottom of the slot of the clamping groove, causing the two bearing platforms to approach each other, ensuring that the two first U-shaped frames do not easily separate when approaching each other. At the same time, the bearing platform limits the pressing platform, making the compression spring in a compressed state. The reaction force generated by the compression spring on the second U-shaped frame prompts the two second U-shaped frames to be connected and not easily separate;

However, it is obvious that for those of ordinary skill in the art, these embodiments may not be limited to these specific details in practice. In some instances, well-known methods and structures are not described in detail to avoid unnecessarily obscuring these embodiments. Additionally, all embodiments can be used in combination with each other.

[0035] Please refer to Figures 1 to 7 , the present invention provides a technical solution: Embodiment 1:

[0036] A sliding type high-altitude bolt installation device for steel structures, comprising: an outer frame 1, an inner frame 2, a limit sleeve 6 and a support rod 10.

[0037] Specifically, the outer frame 1 is formed by splicing two first C-shaped frames 101. Pressure-bearing platforms 3 are fixedly connected to the inner walls at both ends of the outer frame 1. A card slot 4 is formed on the surface of the pressure-bearing platform 3. The structure of the outer frame 1 is as Figure 5 shown. The outer frame 1 is generally rectangular. The inner frame 2 is formed by splicing two second C-shaped frames 5. The splicing seams of the outer frame 1 and the inner frame 2 are perpendicular to each other in a cross shape. That is to say, the two first C-shaped frames 101 and the two second C-shaped frames 5 are offset from each other. When the two second C-shaped frames 5 move away from each other, the second C-shaped frames 5 will be limited by the ends of the first C-shaped frames 101;

[0038] Secondly, two limit sleeves 6 are provided and are respectively fixed to the middle parts of the outer side walls of the two second C-shaped frames 5. A sliding block 7 is movably inserted into the end of the limit sleeve 6. One end of the sliding block 7 is fixedly connected to a pressing platform 8. A V-shaped groove 9 is formed on the surface of the pressing platform 8. The V-shaped groove 9 is buckled on the outside of the two pressure-bearing platforms 3 and is located inside the card slot 4. After the V-shaped groove 9 buckles the adjacent two pressure-bearing platforms 3, the two first C-shaped frames 101 can be pressed, so that the mutual separation and sliding of the two first C-shaped frames 101 are limited, thereby preventing the two first C-shaped frames 101 from separating from each other, and thus ensuring the stability of the structure of the outer frame 1;

[0039] Further, the support rod 10 is horizontally and slidably installed on the outer side of the outer frame 1. An adjusting rod 12 is slidably arranged at the upper end of the support rod 10. One end of the adjusting rod 12 is provided with an internal hexagonal sleeve 13, which is adapted to the bolts on the steel structure. The other end of the adjusting rod 12 is inserted with a polygonal plug rod 14 for driving the adjusting rod 12 to rotate. One end of the polygonal plug rod 14 is fixedly connected with a handle disc 15. When the handle disc 15 is rotated, the transmission between the handle disc 15 and the adjusting rod 12 through the polygonal plug rod 14 can drive the adjusting rod 12 and the internal hexagonal sleeve 13 to rotate, thereby driving the internal hexagonal sleeve 13 to rotate and tighten the bolts. The handle disc 15 is set in the shape of a disc with a large diameter, so as to facilitate the staff to rotate it at high altitude, thus ensuring that the bolts can apply a stronger tightening force to the steel structure. Embodiment 2:

[0040] On the basis of Embodiment 1, in order to fold the adjusting rod 12, the present application further has a guiding cylinder 11 arranged at the upper end of the support rod 10. One end of the guiding cylinder 11 is rotatably connected to the upper end of the support rod 10. The other end of the adjusting rod 12 is movably inserted into the inner cavity of the guiding cylinder 11. The arrangement of the guiding cylinder 11 ensures that the adjusting rod 12 can be tilted and rotated at a certain angle along with the guiding cylinder 11, so as to fold the internal hexagonal sleeve 13 on the side of the support rod 10, reducing the space occupied by the device when it is idle. Embodiment 3:

[0041] On the basis of Embodiment 2, in order to pull the adjusting rod 12 to slide in the inner cavity of the guiding cylinder 11, the present application further has a limiting slider 16 fixedly connected to the other end of the adjusting rod 12. The limiting slider 16 can only slide inside the guiding cylinder 11 to prevent the adjusting rod 12 from detaching from the guiding cylinder 11. A polygonal slot 17 is opened in the middle of the limiting slider 16. The polygonal plug rod 14 is inserted into and adapted to the polygonal slot 17. Therefore, when the polygonal plug rod 14 rotates, it can drive the adjusting rod 12 to rotate. An elastic protrusion 18 is fixedly arranged on the surface of the other end of the polygonal plug rod 14. The arrangement of the elastic protrusion 18 is used to increase the friction force between the polygonal plug rod 14 and the inner wall of the polygonal slot 17, ensuring that the polygonal plug rod 14 can drive the adjusting rod 12 to slide in the inner cavity of the guiding cylinder 11 when being pulled and drawn. Embodiment 4:

[0042] On the basis of Embodiment 3, in order to increase the application range of the present device, a plurality of internal hexagonal sleeves 13 are provided in the present application. The diameters of the plurality of internal hexagonal sleeves 13 increase in sequence and are sleeved with each other. A flange for preventing separation is fixedly arranged on the outer side wall of the internal hexagonal sleeve 13, such as Figure 4As shown in the figure, the provision of multiple hexagon sockets 13 can increase the applicable range of the device, ensuring that the device can turn bolts of multiple different sizes. The provision of the flange is used to prevent the multiple hexagon sockets 13 from separating from each other. One end of the adjusting rod 12 passes through the large-diameter hexagon socket 13 and is fixedly connected to the smallest-diameter hexagon socket 13. Therefore, when the adjusting rod 12 rotates, it can drive the hexagon socket 13 to rotate. Embodiment Five:

[0043] On the basis of Embodiment Four, in order to ensure that the hexagon socket 13 can just fit outside the bolt, the present application further has a retaining ring 19 fixedly connected to the outer side of one end of the adjusting rod 12. A thrust spring 20 is provided between the retaining ring 19 and the hexagon socket 13. The thrust spring 20 provides a thrust force so that the multiple hexagon sockets 13 can maintain a state of being unfolded from each other. By sliding the adjusting rod 12 to press the hexagon socket 13 against the surface of the steel structure, it can be ensured that the hexagon socket 13 corresponding to the size of the bolt can just fit outside the bolt. Embodiment Six:

[0044] On the basis of Embodiment Five, in order to ensure that the sliding block 7 always remains away from the limiting sleeve 6, the present application further has a limiting groove 21 opened on the surface of the limiting sleeve 6. The other end of the sliding block 7 is fixedly connected with a limiting block 22. The limiting block 22 passes through the limiting groove 21 and is slidably connected therewith, which is used to prevent the sliding block 7 from separating from the limiting sleeve 6. The other end face of the sliding block 7 is fixedly connected with a pressing spring 23 located inside the limiting sleeve 6. The pressing spring 23 provides a thrust force to ensure that the sliding block 7 always remains away from the limiting sleeve 6. Embodiment Seven:

[0045] On the basis of Embodiment Six, in order to connect the support rod 10, the present application further has a U-shaped clamping plate 24 fixedly connected to the lower end of the support rod 10. The U-shaped clamping plate 24 is buckled outside the first U-shaped frame 101 and is slidably connected therewith. The inner side wall of the U-shaped clamping plate 24 is fixedly connected with a dovetail slider 25. A dovetail chute 26 is opened on the outer side wall of the first U-shaped frame 101. The dovetail slider 25 is located inside the dovetail chute 26 and is adapted thereto. Therefore, the support rod 10 can only slide horizontally outside the first U-shaped frame 101 and will not tilt or rotate or separate from the first U-shaped frame 101. Embodiment Eight:

[0046] Based on Embodiment VII, in order to prevent the outer frame 1 and the inner frame 2 from deforming and misaligning, the present application further has positioning insertion rods 27 provided on one end face of the first C-shaped frame 101 and one end face of the second C-shaped frame 5, and positioning slots 28 corresponding exactly to the positioning insertion rods 27 are fixedly connected to the other end face of the first C-shaped frame 101 and the other end face of the second C-shaped frame 5. The positioning slots 28 are inserted into the inner cavity of the positioning insertion rods 27 and are adapted thereto. The settings of the positioning slots 28 and the polygonal slots 17 ensure that the two first C-shaped frames 101 and the two second C-shaped frames 5 can be spliced with each other and will not be misaligned. Embodiment IX:

[0047] Based on Embodiment VIII, in order to prevent the two first C-shaped frames 101 from separating from each other, the pressure-bearing platform 3 of the present application is in the shape of a right triangle, and the mutually remote side faces of two adjacent pressure-bearing platforms 3 are symmetrically inclined. The structure of the pressure-bearing platform 3 is as Figure 5 shown, combined with Figure 5 and Figure 6 it can be known that after the V-shaped groove 9 presses on the bottom of the groove of the clamping groove 4 located outside the pressure-bearing platform 3, it can ensure that the two pressure-bearing platforms 3 approach each other, thereby preventing the two first C-shaped frames 101 from easily separating.

[0048] The present invention also discloses an installation method of the sliding-type steel structure high-altitude bolt installation device according to the above, which specifically includes the following steps:

[0049] Step 1: Splice the two second C-shaped frames 5 with each other and hold them on the outside of the steel structure. The two second C-shaped frames 5 are initially fixed through the positioning insertion rods 27 and the positioning slots 28. Then splice the two first C-shaped frames 101 with each other and hold them on the outside of the inner frame 2, ensuring that the pressing platform 8 just snaps into the bottom of the clamping groove 4 located outside the pressure-bearing platform 3 under the thrust of the compression spring 23. At this time, the inner wall of the V-shaped groove 9 squeezes the bottom of the clamping groove 4 to make the two pressure-bearing platforms 3 approach each other, ensuring that the two first C-shaped frames 101 approach each other and will not easily separate. At the same time, the pressure-bearing platform 3 limits the pressing platform 8, making the compression spring 23 in a compressed state. The reaction force generated by the compression spring 23 on the second C-shaped frame 5 prompts the two second C-shaped frames 5 to be connected to each other and will not easily separate;

[0050] Step 2: Then slide the C-shaped clamping plate 24 on the outside of the outer frame 1 to drive the support rod 10 to slide horizontally, align the adjusting rod 12 at the upper end of the support rod 10 with the bolt on the steel structure, and then slide the adjusting rod 12 to sleeved the inner hexagonal sleeve 13 outside the bolt, and drive the adjusting rod 12 to rotate by rotating the handle plate 15, so as to tighten the bolt.

[0051] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
