Description

Technical Field

[0001] The utility model relates to a stainless steel fuse technology for narrow spaces, in particular to a stainless steel wire fuse tooling based on narrow spaces. Background Art

[0002] When working in a small space, the workers' freedom and flexibility are restricted due to the influence of the small space. When working, there is a risk of collision with surrounding objects or accidental injury. Restricted by obstacles in the space, their posture is inconvenient and they cannot fully use their strength. When workers use tools, the possibility of injury increases. In addition, the gas circulation in a small space is poor. Staying in a small space for a long time will lead to insufficient oxygen, accumulation of harmful gases and hypoxia.

[0003] When the existing stainless steel safety tooling for narrow spaces is used, two workers are equipped. One worker wears protective equipment and enters the narrow space, while the other worker observes and warns from the outside. The worker in the narrow space screws the butterfly nut onto the reserved bolt and screws it to the specified torque. Then, the stainless steel wire passes through the reserved hole on the butterfly nut along the specified path. After cutting off the excess length of the stainless steel wire, the two ends of the stainless steel wire are twisted together with needle-nosed pliers to form a twist. However, the original stainless steel wire is in a ring shape, so when using the stainless steel wire to pass through the hole of the butterfly nut, the worker needs to After the personnel straightens the stainless steel wire, they perform punching. However, the length of the stainless steel wire actually used does not match the straightened length of the stainless steel wire. If the straightened length of the stainless steel wire is longer than the actually used stainless steel wire, the straightened stainless steel wire segment is not convenient to be recycled into the original wire ring when the stainless steel wire is recycled. If the straightened length of the stainless steel wire is lower than the actual usage requirement, the personnel are required to straighten it in a narrow space, which increases the difficulty of the work. In addition, the use of needle-nosed pliers in a narrow space to rotate and twist the two ends of the stainless steel wire together has a large amplitude and many obstacles, which takes a lot of time and increases the risk of working in a small space.

[0077] Embodiment 2:

[0078] See also Figure 1 , Figure 6 and Figure 7 This embodiment provides a technical solution based on the first embodiment: the clamping member 4 includes:

[0079] A driving tooth 44, which is fixedly mounted on the other end of the transmission shaft 37;

[0080] Two driven teeth 45, whose external gears are respectively meshed and connected with the external gears of the driving teeth 44;

[0081] The bottoms of the connecting plate 47 on both sides are rotatably connected to the tops of the driven teeth 45;

[0082] Two limiting rods 42, one side bottom of which is respectively fixedly connected to the top of the driven gear 45;

[0083] The limiting ring 41 is fixedly mounted on the bottom of the box body 11, and its inner wall is slidably connected to the other side of the limiting rod 42;

[0084] The limiting plate 43 has a bottom middle portion rotatably connected to the top of the driving gear 44, and two sides thereof are slidably connected to the inner wall of the limiting ring 41;

[0085] The annular gear ring 46, whose inner wall gear is simultaneously meshed and connected to the two driven teeth 45 outer gear rings;

[0086] The top of the washer 48 is rotatably connected to the bottom of the annular gear ring 46 , and the bottom of the washer 48 is fixedly connected to the bottom of the box body 11 .

[0087] The specific implementation is as follows: when the power source 2 36 drives the active tooth 44 to rotate counterclockwise, the active tooth 44 drives the two driven teeth 45 to rotate clockwise, driving the two limit rods 42 thereon to approach the arc-shaped side of the limit plate 43 until the limit rod 42 applies force to the limit plate 43, and the driven tooth 45 stops rotating, driving the annular gear ring 46 to rotate. The friction between the bottom of the annular gear ring 46 and the washer 48 is relatively large, and the friction between the limit plate 43 and the limit ring 41 is relatively large, ensuring the clamping of the stainless steel wire. The power source 2 36 continues to rotate, and the stainless steel wires clamped at both ends are wound into a twist shape. When the tightness reaches the set threshold, the power source 2 36 automatically reverses a certain angle and stops, removes the equipment, and uses needle-nosed pliers to handle the tangled stainless steel wires.

[0088] Working principle: When in use, the worker inserts the stainless steel wire along the groove at the back of the box body 11, and through the adjacent groove of the adjusting wheel 23, uses the adjusting piece 13 to adjust the position of the adjusting plate 21, so that the annular groove in the middle of the adjusting wheel 23 on both sides has a suitable pressing force on the stainless steel wire, and continues to pass the stainless steel wire to the other side of the box body 11 to the side of the annular groove located on the driven wheel 24 and the driving wheel 25, and starts the power source 1 31 to squeeze the stainless steel wire out of the box body 11 to the annular tube on the side of the plate 1 26 and the plate 2 27, aligns the extended stainless steel wire with the reserved hole on the butterfly nut, and after the stainless steel wire passes through one end of the reserved hole of the butterfly nut to a certain size, use the adjusting piece 13 to adjust the adjusting plate 21 to the side away from the fixed plate 22, and remove the device. If the position of the reserved hole of the other butterfly nut is not convenient for clamping with needle-nosed pliers in a narrow space, the stainless steel wire can be loaded into the device again, and the thrust of the device is used to pass the stainless steel wire through the other butterfly nut. The reserved hole of a butterfly nut is used to pass the stainless steel wire through the standard path, and then the excess stainless steel wire is cut off. The two joints of the stainless steel wire are placed on one side of the ring of the limit rod 42, and the power source 2 36 is started. When the power source 2 36 drives the active tooth 44 to rotate counterclockwise, the active tooth 44 drives the two driven teeth 45 to rotate clockwise, driving the two limit rods 42 thereon to approach the arc-shaped side of the limit plate 43 until the limit rod 42 applies force to the limit plate 43, and the driven tooth 45 stops rotating, driving the annular gear ring 46 to rotate. The friction between the bottom of the annular gear ring 46 and the washer 48 is large, and the friction between the limit plate 43 and the limit ring 41 is large, ensuring the clamping of the stainless steel wire. The power source 2 36 continues to rotate, and the stainless steel wires clamped at both ends are wound into a twist shape. When the tightness reaches the set threshold, the power source 2 36 automatically reverses a certain angle and stops, removes the equipment, and uses needle-nosed pliers to handle the tangled stainless steel wires.

[0089] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
