Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering auxiliary tools, in particular to an auxiliary mechanism for tying steel bars of cast-in-situ shear walls. Background Art

[0002] A tie hook is a tool that fastens the tie wire at the connection point of the steel bars, so that the steel bars are tightly connected together and prevent the steel bars from being dislocated during the pouring process. Tie hooks are usually required in the steel bar binding stage of cast-in-place shear walls. Traditional tie hooks require construction workers to rotate the tie hooks significantly to work, which has low construction efficiency and consumes physical strength. Therefore, electric tie hooks that can save manpower have emerged.

[0003] At present, some existing electric hooks, such as the patent with publication number CN211714612U, disclose an electric hook for construction, including a housing, a power button, a rubber sleeve, a motor, a connecting seat, a battery, a charging socket, a hook head, and a screw. The power button is embedded below the outer wall of the housing, and the rubber sleeve is mounted on the outside of the housing and located above the power button to prevent slipping. The motor, battery, and charging socket are embedded in the housing from bottom to top, wherein the rotating shaft of the motor is exposed at the bottom of the housing and connected to the connecting seat and fixed with a bolt. The top of the hook head is embedded in the groove at the bottom of the connecting seat and fixed with a screw. It has a simple structure and low cost. The motor drives the hook head to rotate to tighten the wire, replacing traditional manual hooks and semi-automatic hooks, effectively improving work efficiency and construction quality. However, the hook head is relatively sharp and is not easy to store when not in use. In addition, when the hook is in use, the hook head is often entangled with the wire and tightened. At this time, the hook head needs to be retracted to make the hook head disengage from the wire buckle. Long-term manual operation is not only laborious but also inefficient.

[0004] How to store the hook head when it is not in use, facilitate the storage and movement of the hook, avoid the hook head from hurting the operator, and easily retract the hook head when it is entangled, saving labor and improving operational efficiency has become a technical problem that needs to be broken through.

[0005] In summary, the existing technology has obvious inconveniences and defects in actual use, so it is necessary to improve it. Utility Model Content

[0021] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0022] See also Figures 1 to 3The utility model provides an auxiliary mechanism for tying steel bars of a cast-in-place shear wall, comprising a shell 1, a rotating button 14 being provided on the shell 1, the rotating button 14 being electrically connected to a driving member 3 located inside the shell 1, the driving member 3 being connected to the shell 1, an energy storage device being provided below the driving member 3 (mostly a battery is used, no need to plug in a cable for charging, and easy to replace), a controller being provided between the rotating button 14, the driving member 3 and the energy storage device, the driving member 3 being turned on by pressing the rotating button 14, and the energy storage device supplying power to the driving member 3 (the coordination relationship between the controller, the switch, the motor and the energy storage device is a mature existing technology, and its specific electrical connection method and working principle are not described in detail here), the output shaft of the driving member 3 is connected to an active rod 31, the driving member 3 can drive the active rod 31 to rotate, a hook head 11 is provided on a sliding sleeve on the active rod 31, and the top end of the hook head 11 passes through the shell 1 The hook head 11 can be raised and lowered on the active rod 31, and the active rod 31 can drive the hook head 11 to rotate (there are many ways in which the active rod 31 can be raised and lowered in the hook head 11 and can drive the hook head 11 to rotate. For example, the active rod 31 is a square rod, and a square groove that cooperates with the square rod is provided in the hook head 11). A positioning ring 111 is provided on the hook head 11 in the outer shell 1. The positioning ring 111 is slidably connected to the outer shell 1. An elastic member 4 is provided between the positioning ring 111 and the outer shell 1. The positioning ring 111 will not drive the elastic member 4 to rotate. When the positioning ring 111 moves up and down, the elastic member 4 provides elastic force (for example, the positioning ring 111 abuts against the elastic member 4). When the elastic member 4 is in a natural state, the elastic member 4 can prevent the hook head 11 from moving upward; the bottom end of the outer shell 1 is threadedly connected to the movable cover 12. By opening the movable cover 12, the energy storage device can be directly replaced or charged.

[0023] See also Figures 1 to 3 Specifically, the driving member 3 is a rotating motor that provides power for the device.

[0024] See also Figures 1 to 3, a shielding plate 5 is elastically connected to one side of the shell 1 (a slider is provided on the shielding plate 5, and a slideway 16 cooperating with the slider is provided on the shell 1, the slider is slidably arranged in the slideway 16, and an elastic member 4 is provided between the slider and the slideway 16). When the elastic member 4 is in a natural state, the top of the shielding plate 5 is higher than the top of the hook head 11, and the lower part of the shell 1 is threadedly connected to a positioning member 15, and the shielding plate 5 is provided with a positioning hole 51 cooperating with the positioning member 15. When the shielding plate 5 is pulled downward, the positioning member 15 and the positioning hole 51 cooperate with each other, which can prevent the elastic member 4 from doing work to make the shielding plate 5 slide up to the initial position, thereby avoiding obstruction of the hook head 11; the shell 1 above the rotating button 14 is symmetrically elastically connected with a telescopic button 1 3 (the telescopic buttons 13 are all inserted into the shell 1, and the telescopic buttons 13 in the shell 1 are symmetrically provided with plug-ins. A slot that cooperates with the plug-in block is provided in the shell 1, and the plug-in block is slidably set in the slot, and an elastic member 4 is provided between the plug-in block and the slot). The telescopic buttons 13 in the shell 1 are all connected to the trigger head 2 that cooperates with the hook head 11. The telescopic buttons 13 are squeezed from both sides of the shell 1 at the same time, and the telescopic buttons 13 drive the trigger head 2 to move toward the center at the same time. The trigger head 2 squeezes the hook head 11 at the same time, so that the hook head 11 moves upward for a distance. At this time, the positioning ring 111 squeezes the elastic member 4 at the positioning ring 111, and the plug-in block squeezes the elastic member 4 at the plug-in block. When the telescopic button 13 is released, the hook head 11 returns to its initial position.

[0025] See also Figures 1 to 3 Preferably, the elastic member 4 is a spring to provide return power.

[0026] See also Figures 1 to 3 Preferably, one end of the trigger head 2 close to the hook head 11 and one end of the hook head 11 close to the trigger head 2 are both provided with mutually matching inclined surfaces to facilitate matching and reduce friction during contact.

[0027] See also Figures 1 to 3 When it is necessary to tie the steel bars, pull the shield plate 5 downward, and fix the position of the shield plate 5 through the cooperation between the positioning piece 15 and the positioning hole 51. Then, control the rotating button 14 to make the hook head 11 rotate intermittently to perform the binding operation. When the hook head 11 is entangled, squeeze the telescopic button 13 once at the same time to help the hook head 11 break away from the binding wire. After use, the positioning piece 15 and the positioning hole 51 are disengaged, and the shield plate 5 automatically moves up to block the hook head 11 (if the hook head 11 is facing the direction not blocked by the shield plate 5, control the rotating button 14 to rotate the hook head 11 to the side close to the shield plate 5).

[0028] The utility model provides an auxiliary mechanism for tying steel bars of cast-in-place shear walls, including an elastically connected shielding plate, which cooperates with the elastic member to store the hook head when not in use, so as to prevent the hook head from injuring the operator; squeezing the telescopic button, which simultaneously drives the trigger head to move toward the center, and the trigger head simultaneously squeezes the hook head, so that the hook head moves upward for a distance, and when the hook head is entangled, the hook head can be easily retracted to help the hook head break away from the wire, thus saving labor and improving operating efficiency. In summary, the beneficial effects of the utility model are: when the hook is not in use, the hook head can be stored, which is convenient for the storage and movement of the hook, thus preventing the hook head from injuring the operator; when the hook head is entangled, the hook head can be easily retracted, thus saving labor and improving operating efficiency.
