DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present utility model.

[0027] Embodiment 1

[0028] Please refer to Figure 1 - Figure 4, a sliding type high-altitude bolt installation device for steel structures provided by the present utility model includes: a U-shaped frame one 1 sleeved on the steel structure, with sliding grooves 2 opened on both sides of the inner wall of the U-shaped frame one 1, and a guiding groove 3 communicated with the sliding groove 2 opened on one side of the top of the U-shaped frame one 1;

[0029] a U-shaped frame two 4 slidably connected in the sliding groove 2;

[0030] a connecting block 5 fixedly installed on one side of the top of the U-shaped frame two 4 and slidably connected with the guiding groove 3, with a screw hole opened on the connecting block 5;

[0031] a fixing block 6 fixedly installed on one side of the top of the U-shaped frame one 1;

[0032] a screw rod 7 penetrating through the fixing block 6 and rotatably connected with the fixing block 6, and threadedly connected with the screw hole, with a rotating handle fixedly connected to one end of the screw rod 7;

[0033] and a bolt installation mechanism jointly slidably arranged on the surfaces of the U-shaped frame one 1 and the U-shaped frame two 4.

[0034] Preferably, a guiding groove 8 is opened on the outer surface of the U-shaped frame one 1, and dovetail grooves 9 are opened on the inner wall of the guiding groove 8 and the outer surface of the U-shaped frame two 4.

[0035] Anti-slip pads 10 are fixedly installed on one side of the inner wall of the U-shaped frame one 1 and one side of the inner wall of the U-shaped frame two 4.

[0036] The technical solution provided by this embodiment is as follows: When fastening bolts for steel structures of different sizes, the opening of the U-shaped frame one 1 is passed through the steel structure so that the two are in contact, and then the U-shaped frame two 4 is slid into the sliding groove 2 to seal the opening of the U-shaped frame one 1, so that the connecting block 5 enters the guiding groove 3, and the end of the screw rod 7 is aligned with the screw hole on the connecting block 5. At the same time, the rotating handle is rotated to drive the screw rod 7 to rotate, so that the connecting block 5 moves in the guiding groove 3 and is screwed onto the screw rod 7, and under the action of the thread, the U-shaped frame two 4 is driven to move towards the U-shaped frame one 1 in the sliding groove 2. As the U-shaped frame two 4 moves forward, the U-shaped frame two 4 gradually contacts the steel structure, and then the U-shaped frame one 1 and the U-shaped frame two 4 are clamped and fixed on the steel structure. At the same time, the contact effect between the U-shaped frame one 1 and the U-shaped frame two 4 and the steel structure is increased through the anti-slip pads 10. Therefore, under the action of the cooperation and clamping fixation of the U-shaped frame one 1 and the U-shaped frame two 4, the effect of facilitating the adjustment of the frame size according to steel structures of different sizes is achieved, so as to facilitate the assembly of the frame on steel structures of different sizes, avoid the situation that the frame size is fixed and cannot adapt to steel structures of different sizes, reduce the use limitations, and effectively improve the use range and use flexibility.

[0037] Further, the bolt installation mechanism includes a dovetail block 11 slidably connected in the dovetail groove 9, a mounting plate 12 provided on one side of the dovetail block 11 and having a groove at the top, an adjusting component provided on one side surface of the dovetail block 11 for adjusting the distance between it and the mounting plate 12, and a twisting component provided on the mounting plate 12 for tightening the bolt. Card slot openings 13 are formed on both side surfaces at the top of the mounting plate 12.

[0038] Specifically, when installing the bolt, the position is adjusted by moving the mounting plate 12 to drive the dovetail block 11 to slide in the dovetail groove 9 on the U-shaped frame two 4 through the adjusting mechanism, which is convenient for tightening the bolt on one side of the U-shaped frame two 4. When tightening the bolt on one side of the guiding groove 8, the dovetail block 11 slides out of the dovetail groove 9 on the U-shaped frame two 4 and enters the guiding groove 8 for sliding adjustment. When tightening the bolt on the opposite side of the steel structure U-shaped frame four 4, the dovetail block 11 can slide out of the guiding groove 8 and enter the dovetail groove 9 in the U-shaped frame one 1, so as to tighten the bolts at different positions around the steel structure. During the tightening process, the distance between the twisting component and the bolt is adjusted by the adjusting component, and the bolt is tightened by the twisting component.

[0039] Further, the twisting component includes an electric wrench 14 provided in the groove at the top of the mounting plate 12, two clamping columns 15 symmetrically and fixedly installed on the surface of the electric wrench 14 and engaged with the card slot openings 13, and a bolt sleeve 16 connected to the output end of the electric wrench 14.

[0040] Specifically, by moving the electric wrench 14, the clamping columns 15 are inserted into the card slot openings 13, and the bolt sleeve 16 is installed at the output end of the electric wrench 14. Then, the distance between the electric wrench 14 and the bolt is adjusted by the adjusting component, and at the same time, the angle of the electric wrench 14 is adjusted so that the bolt sleeve 16 is sleeved on the bolt. The bolt can be tightened by driving the bolt sleeve 16 to rotate by the electric wrench 14. After tightening, the electric wrench 14 is moved to separate the clamping columns 15 from the card slot openings 13, and then the electric wrench 14 can be removed.

[0041] Further, the adjusting component includes a rectangular sleeve 17 fixedly installed on one side surface of the dovetail block 11, a movable plate 18 slidably connected in the rectangular sleeve 17, and a hand-tightening bolt 19 threadedly connected through the top of the rectangular sleeve 17 and abutting against the movable plate 18. The movable plate 18 is connected to the mounting plate 12, and the rectangular sleeve 17 is slidably matched with the guiding groove 8.

[0042] Specifically, when tightening the bolt, loosen the hand-tightened bolt 19, then move the mounting plate 12 to drive the movable plate 18 to slide within the rectangular housing 17, so that the electric wrench 14 drives the bolt sleeve 16 to move and fit over the bolt. Then, drive the bolt sleeve 16 to rotate through the electric wrench 14 to tighten the bolt. After tightening, adjust the movable plate 18 to be retracted into the rectangular housing 17 and tighten it with the hand-tightened bolt 19 to prevent the movable plate 18 from accidentally moving and occupying too much space. When tightening the bolt on one side of the guiding groove 8 and the dovetail block 11 slides out of the dovetail groove 9 on the U-shaped frame II 4, at this time, the rectangular housing 17 replaces the dovetail block 11 to slide and adjust the position in the guiding groove 8, which is convenient for tightening bolts at different positions of the steel structure.

[0043] Embodiment 2

[0044] Based on Embodiment 1, in this embodiment: Two pin holes penetrating through the card slot openings 13 are symmetrically formed on one side surface of the mounting plate 12, and a limit pin rod 20 penetrates through the pin holes.

[0045] The technical solution provided in this embodiment is: After the electric wrench 14 is installed, insert the limit pin rod 20 into the pin hole to facilitate limiting the clamping column 15 and prevent the electric wrench 14 from accidentally falling, ensuring the stability of use.

[0046] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
