Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The tool for safely processing the steel bar head 4 comprises a knocking tool for knocking the steel bar head 4 and a removing tool 3 for removing the steel bar head 4, which are described below.

The beating tool comprises a first component 1 and a second component 2 which are matched for use. The first assembly 1 comprises a first holding rod 11, and a rubber sleeve 5 is fixed at the hand-holding end of the first holding rod 11 and used for preventing skidding and preventing shock. One end far away from the hand-held end of the first holding rod 11 is connected with a steel fixed cylinder 12, the upper end face of the fixed cylinder 12 faces upwards and is welded with a steel beating cylinder 13, and the lower end face of the fixed cylinder 12 faces downwards and is welded with a steel sleeve 14. Wherein the inside of the sleeve 14 is hollow, the inner diameter of the hollow part of the sleeve 14 is just equal to the diameter of the steel bar head 4, the sleeve 14 is used to cover the upper part of the steel bar head 4, and then the hammer head is used to strike the upper surface of the knocking cylinder 13. Since the construction space is limited in many cases, it is preferable that the first grip 11 is rotatably connected to the fixed cylinder 12, and specifically, the fixed cylinder 12 is vertically welded to the connecting block 15, the end of the first grip 11 is located in the middle of the connecting block 15, the fixed shaft 16 passes through the connecting block 15 and the first grip 11, and both ends of the fixed shaft 16 are fixed to the connecting block 15 by bolts, so that the first grip 11 can rotate around the fixed shaft 16. When the construction space is narrow, the first grip 11 may be rotated upward or downward to accommodate the construction space.

The second assembly 2 comprises a second holding rod 21, a rubber sleeve 5 is also fixed at the hand-held end of the second holding rod 21, and the rubber sleeve 5 is used for preventing skidding and preventing vibration. One end far away from the holding end of the second holding rod 21 is fixedly connected with a rectangular block 22, and the upper end surface and the lower end surface of the rectangular block 22 are both fixed with rubber limiting blocks A23. The middle part of the outward end of the rubber limiting block A23 is provided with an arc-shaped opening 24, namely the middle part of the end far away from the hand holding end is provided with the arc-shaped opening 24, and the arc-shaped opening 24 is used for clamping the reinforcing steel bar head 4. A rubber limiting block B25 is further fixed on the other side face of the rectangular block 22, and the rubber limiting block B25 is perpendicular to the rubber limiting block A23. The rubber stopper B25 is L-shaped as a whole, and the outward end of the rubber stopper B25 is an inward hook-shaped arc surface 26 as shown in fig. 5. The two arc-shaped openings 24 and the hook-shaped arc surface 26 clamp the reinforcement bar head 4 into the arc-shaped openings 24 and limit the reinforcement bar head 4 through the arc surface 26. The hook-shaped arc surface 26 can enable the reinforcing steel bar head 4 to slide into the arc-shaped opening 24 along the arc surface 26 and also slide out of the arc-shaped opening 24 along the arc surface 26.

The pulling-out tool 3 comprises a fixed block 31, two arc-shaped holding rods 32 are symmetrically and rotatably connected to the fixed block 31, similarly, rubber sleeves 5 are arranged at the holding ends of the arc-shaped holding rods 32, one ends of the arc-shaped holding rods 32, which are far away from the holding ends, are arc-shaped ends 33, and the lower parts of the arc-shaped ends 33 are rotatably connected with the fixed block 31 through pin shafts 34, so that the arc-shaped holding rods 32 can rotate around the pin shafts 34 on the plane of the fixed block 31. The upper part of the arc end 33 is provided with a gap, and the gap is fixedly connected with a rubber column A35. Since the position of the pin 34 is not located at the center of the arc end 33, the distance between the two rubber columns a35 gradually decreases when the two arc-shaped holding rods 32 rotate upwards, and the distance between the two rubber columns a35 gradually increases when the two arc-shaped holding rods 32 rotate downwards. The arc-shaped holding rods 32 can clamp the steel bar head 4 to be processed when rotating upwards, and the clamping is more tight when rotating upwards, namely at least when the distance between the two rubber columns A35 is minimum, the distance between the two rubber columns A35 is smaller than the diameter of the steel bar head 4. Two rubber columns B36 are symmetrically fixed on the fixing block 31 above the rubber column A35, the distance between the two rubber columns B36 is not more than the diameter of the reinforcing steel bar head 4, and because the rubber has certain elasticity, the distance between the two rubber columns B36 is optimally slightly less than the diameter of the reinforcing steel bar head 4, and the two rubber columns B36 have clamping, positioning and guiding functions. The heights of the rubber columns A35 and B36 are larger than the diameter of the steel bar head 4.

When the invention is used, if the reinforcing steel bar head 4 needs to be beaten into the ground, a worker holds the component two 2 to clamp the middle part of the reinforcing steel bar head 4 into the arc-shaped opening 24, then vertically places the reinforcing steel bar head 4 at the ground position to be beaten, the second holding rod 21 is horizontal, and the worker tightly holds the second holding rod 21 to keep the verticality of the reinforcing steel bar head 4. Then another worker puts the sleeve 14 of the first unit 1 over the bar head 4, holds the first grip 11 with one hand, and strikes the striking cylinder 13 downwards with the hammer head with the other hand until the bar head 4 is moved to a desired position. In the whole process, the reinforcing steel bar head 4 cannot be inclined due to the positioning of the second component 2, and the accident that the hands are injured by mistaken striking cannot occur, and the injury of vibration to the hands of workers is basically eliminated in the whole striking process due to the design of the first holding rod 11 and the second holding rod 21.

When needing to pull out existing reinforcing bar head 4, then use and pull out instrument 3, workman's both hands hold the arc holding rod 32 of both sides respectively, earlier with arc holding rod 32 downwardly rotating for the distance between the rubber column A35 is greater than the diameter of reinforcing bar head 4, then earlier with reinforcing bar head 4 card in between two rubber columns B36, then both hands upwards rotate arc holding rod 32, make two rubber columns A35 tightly clip reinforcing bar head 4, then it can to pull out reinforcing bar head 4 to go up arc holding rod 32. If the resistance is larger, the arc-shaped holding rod 32 can be rotated when the arc-shaped holding rod 32 is pulled upwards, so that the steel bar heads 4 clamped in the middle rotate together, the steel bar heads 4 can be loosened through rotation, the steel bar heads are easier to pull out, and the pulling-out tool 3 is safer and more labor-saving when in use.

Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; those of ordinary skill in the art will understand that: the technical solutions described in the above embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
