[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.
[0023] like Figure 1-4 As shown, an auxiliary support tool for a heavy-duty pneumatic wrench includes a base plate 1;
[0024] Also included is a driving assembly and a lifting assembly for supporting the pneumatic wrench;
[0025] Among them, the driving component includes a supporting column 2 arranged on the top of the base plate 1, a driving screw 3 rotatably arranged on the supporting column 2, and the driving screw 3 is vertically distributed, a traction block 4 is sleeved on the outside of the driving screw 3, and a servo motor 5 is arranged at one end of the driving screw 3. The lifting component includes a linear guide rail 7 arranged on the supporting column 2, two groups of limit sliders 8 slidably sleeved on the outside of the linear guide rail 7, a lifting column 9 arranged on a group of limit sliders 8, a wrench fixing seat 10 arranged at the top of the lifting column 9, a nitrogen spring 11 arranged at the bottom of the lifting column 9, and a connecting plate 12 arranged at the bottom of the nitrogen spring 11, and one side of the connecting plate 12 is connected to the other group of limit sliders 8, and one end of the connecting plate 12 is connected to the traction block 4. The pneumatic wrench is installed through the wrench fixing seat 10. When the height of the wrench needs to be adjusted, the servo motor 5 is used to adjust the height of the wrench. The servo motor 5 causes the driving screw rod 3 to rotate, thereby driving the traction block 4 to move. The movement direction of the traction block 4 can be controlled by changing the rotation direction of the driving screw rod 3, thereby realizing the up and down movement of the traction block 4. When the traction block 4 moves, the connecting plate 12 connected thereto also moves accordingly. The movement of the connecting plate 12 drives the lifting column 9 to move up and down, so that the staff can adjust the height of the pneumatic wrench in real time during use. The two sets of limit sliders 8 are mounted on the linear guide rails 7, which can form a good guiding and limiting effect on the up and down movement of the traction block 4 and the lifting column 9, ensuring the stability of the two during movement. The set nitrogen spring 11 can effectively absorb the impact force of the wrench when disassembling and assembling bolts, and can descend along with the bolt disassembly action within a certain stroke, ensuring the smooth progress of the bolt disassembly work.
[0026] In this embodiment, specifically, an axle seat for supporting the driving screw 3 is provided on the support column 2, and positioning blocks 6 are symmetrically provided on the support column 2. The positioning blocks 6 can limit the extreme movement distances of the upper and lower ends of the traction block 4 when the traction block 4 moves up and down, thereby avoiding damage to the device itself caused by excessive limitation.
[0027] In this embodiment, specifically, a force control handle 13 and an emergency stop switch 14 are provided on the lifting column 9, an anti-slip rubber sleeve is provided on the outside of the force control handle 13, a protective shell 15 is provided on the top of the base plate 1, and the protective shell 15 is located on the outside of the drive component and the lifting component, a control box 16 is provided on the top of the base plate 1, and the control box 16 is located on one side of the protective shell 15, the control box 16 is electrically connected to the servo motor 5, the force control handle 13 and the emergency stop switch 14, and a caster 17 for movement is provided at the bottom of the base plate 1. When the device is in use, the protective shell 15 forms a good contact with the drive component and the lifting component. Protection effectively avoids collision between external objects and the two, greatly reducing the risk of damage to the drive assembly and the lifting group due to collision. The staff can pull the force control handle 13 upward or downward by grasping the column, so that the force control handle 13 sends a corresponding electrical signal to the control box 16, and the control box 16 controls the rotation direction of the servo motor 5, thereby realizing precise control of the movement of the lifting assembly. The emergency stop switch 14 can forcibly interrupt the operation of the device after being pressed, so that the device can be promptly deactivated in the event of an accident, and the casters 17 can move the device as a whole.
[0028] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
