Description

Technical Field

[0001] The utility model relates to the technical field of bolt fixing, in particular to a stud bolt fixing device that is convenient for disassembly and assembly. Background Art

[0002] In the existing fixing device technology, for components that need to be frequently disassembled, assembled or replaced, such as stud bolts, the traditional method is usually to fix them through threaded connection. However, this traditional method has many deficiencies. First, frequent disassembly and assembly easily lead to thread wear, thereby affecting the tightness of the connection; second, in threaded connection, operators often need to use tools, such as wrenches or screwdrivers, which not only increases the operation complexity, but also is difficult to operate in a space-restricted environment; in addition, the traditional method is prone to cause part damage during disassembly and assembly, reducing the service life of the equipment.

[0003] A Chinese patent with the publication number CN215165790U discloses a convenient disassembly and assembly anchor bolt fixing device. The patent includes a positioning frame and a suspension bracket detachably connected to the positioning frame. Fixed plates are provided at the four corners of the positioning frame, and each fixed plate is provided with a fixing hole for inserting a pin to fix with the template to prevent vibration displacement during pouring. A positioning plate is arranged inside the positioning frame, and a bolt hole for fixing the anchor bolt is provided on the positioning plate. The structure of this patent is simple and reasonably designed. The positioning and installation are simple. It can effectively prevent the disturbance of the anchor bolt during the concrete pouring process, resulting in the displacement of the anchor bolt, and can accurately control the position of the anchor bolt to ensure the forming quality of the anchor bolt, and is convenient for suspension and disassembly, greatly improving the construction efficiency.

[0004] Based on the above search and combined with the existing technology, it is found that:

[0005] In the existing device, pins are inserted into the fixing holes around to fix with the template to prevent vibration displacement during pouring. After the concrete begins to set, the pins and the bolt caps are removed, and the suspension bracket is fixed above the positioning frame and lifted by a crane to improve the replacement efficiency. However, after the pouring is completed, the pins and the bolt caps on the stud bolts need to be removed before the positioning frame can be lifted and taken out. Frequent disassembly and assembly easily lead to thread wear, thereby affecting the tightness of the connection, which is not conducive to practical use. Summary of the Utility Model

[0006] In order to solve the above technical problems, the utility model provides a stud bolt fixing device that is convenient for disassembly and assembly. By the operation of an air pump, the pneumatic chuck can clamp and fix the stud bolt. After fixing, the concrete can be poured.

[0021] The utility model is described in detail below, and the technical solutions in the embodiments of the utility model are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0022] The utility model provides a foot nail bolt fixing device which is convenient for disassembly and assembly through improvement. The technical solution of the utility model is:

[0023] like Figures 1 - 4 As shown, a foot nail bolt fixing device which is easy to disassemble and assemble comprises a fixing base 1, a pair of support plates 2 are fixedly installed on both sides of the fixing base 1, a pair of fixing pins 3 are fixedly installed on the bottom of the pair of support plates 2, a pair of support frames 4 are fixedly installed between the pair of support plates 2, a pair of air pumps 5 are fixedly installed on the pair of support frames 4, a pair of connecting columns 6 are fixedly installed on the bottom of the pair of support frames 4, the other end of each pair of connecting columns 6 is connected to a pneumatic chuck 7, the pneumatic chuck 7 is connected to a connecting pipe 8, and the other end of the connecting pipe 8 is connected to the air pump 5.

[0024] Further, a stud bolt 9 is clamped on the pneumatic chuck 7. A plurality of placement holes 10 are formed in the fixed base 1. The stud bolt 9 passes through the placement holes 10 and extends below the pneumatic chuck 7. A plurality of pairs of sliding grooves 11 are formed in the fixed base 1. Each pair of sliding grooves 11 is respectively arranged on both sides of the plurality of placement holes 10. One side of the stud bolt 9 to be used passes through the placement holes 10 in the fixed base 1 and extends to the position of the pneumatic chuck 7. Since the pneumatic chuck 7 is connected to the air pump 5 through the connecting pipe 8, the pneumatic chuck 7 can clamp and fix the stud bolt 9 by the operation of the air pump 5. After fixation, concrete can be poured.

[0025] Further, a spring 12 is installed inside each pair of sliding grooves 11. The other ends of the plurality of springs 12 are all connected to a sliding block 13. The sliding block 13 is slidably connected to the sliding groove 11. The other end of the sliding block 13 is connected to a contact head 14. The contact head 14 passes through the sliding groove 11 and extends to the placement hole 10. The contact head 14 is arc-shaped.

[0026] Further, a support block 15 is fixedly installed on the sliding block 13. A damping rotating shaft 16 is rotatably connected to the support block 15. An activity plate 17 is fixedly installed on the damping rotating shaft 16. A plurality of limiting plates 18 are fixedly installed on the fixed base 1. The plurality of limiting plates 18 are respectively arranged on one side of the plurality of sliding grooves 11. Pull the support block 15 backward and rotate the activity plate 17 to make it contact with the limiting plate 18, so that the stud bolt 9 no longer receives the acting forces of the two contact heads 14 on both sides.

[0027] Further, a mounting plate 19 is connected between a pair of support frames 4. A lifting ring 20 is fixedly installed on the mounting plate 19. A lifting tool can be used to connect to the lifting ring 20 to lift and move the entire device.

[0028] The specific working method is as follows: the device is provided with a fixed base 1, and the bottom of the support plate 2 connected on both sides of the fixed base 1 is connected with a fixed pin 3. The fixed base 1 is fixed by inserting the fixed pin 3 into the ground. When the foot bolt 9 needs to be fixed, one side of the foot bolt 9 to be used passes through the placement hole 10 on the fixed base 1 and extends to the position of the pneumatic chuck 7. Since the pneumatic chuck 7 is connected to the air pump 5 through the connecting pipe 8, the pneumatic chuck 7 can clamp and fix the foot bolt 9 through the operation of the air pump 5. After fixing, concrete can be poured. Sliding blocks 13 are connected in the slide grooves 11 on both sides of the placement hole 10 through springs 12. The abutment heads 14 connected to the sliding block 13 can abut and fix the two sides of the foot bolt 9, thereby preventing the position of the foot bolt 9 from shifting when pouring concrete. After waiting for the concrete to solidify, the support block 15 is pulled backward, and the movable plate 17 is rotated to make it abut against the limit plate 18, so that the foot bolt 9 is no longer subjected to the force of the abutment heads 14 on both sides. Then the pneumatic chuck 7 is used to loosen the foot bolt 9, and then the lifting tool is used to connect the lifting ring 20 to lift and remove the entire device. The device fixes the foot bolt 9 through the pneumatic chuck 7, making fixation and disassembly more convenient, and solving the problem of thread wear caused by bolt fixation, thereby affecting the tightness of the connection.
