The indicator light 27 is normally bright green when the device is in a standby state, the indicator light 27 is normally bright red when the device is in compression, the indicator light is flashing red when the device is in compression, and the buzzer 28 sounds for a long time. When the power supply 25 is in a shortage, the indicator lamp 27 is normally bright yellow. The operator can judge the corresponding state of the device according to the color and state of the indicator lamp 27. The key group 29 includes a + key, -key, on-off key, and execute key; wherein + key and-key are used to control the upper jaw body 3 to move up and down, and the pressing mechanism is started to press the 8-shaped double-hole aluminum sleeve 32 by executing the key.
The device uses 8-shaped double Kong Lvtao with different specifications, in particular: before use, the third driver 8 is controlled to rotate forward or reversely by pressing a + key or a-key according to the 8-shaped double-hole aluminum sleeve 32 with different specifications through the controller, so that the upper clamp body 3 is adjusted to move upwards or downwards to adapt to the size of the 8-shaped double-hole aluminum sleeve 32, and the device is suitable for 8-shaped double Kong Lvtao 32 with various specifications and has strong universality.
The present device replaces manual clamping pliers, in particular: when the double-hole aluminum sleeve 32 is used, the 8-shaped double-hole aluminum sleeve 32 is placed on the upper clamp body 3 and the lower clamp body 3, the execution key is pressed, the first driver 15 and the second driver 18 are rotated through the control module 2, and accordingly the first eccentric wheel 13 and the second eccentric wheel 16 are deflected at a certain angle at the same time, so that the double-hole aluminum sleeve 32 is extruded, and the lower part of the double-hole aluminum sleeve 32 is deformed. Then the 8-shaped double-hole aluminum sleeve 32 is turned over for 180 degrees, the upper part of the 8-shaped double-hole aluminum sleeve 32 is deformed in the same way, and the steel wire rope in the 8-shaped double-hole aluminum sleeve 32 is firmly clamped after the upper part and the lower part of the 8-shaped double-hole aluminum sleeve 32 are deformed. The first eccentric wheel 13 and the second eccentric wheel 16 in the device simulate the jaws of manual clamping pliers, replace manual clamping pliers for clamping, reduce the physical output of operators and lighten the working pressure.
The equipment can ensure the connection strength of the 8-shaped double-hole aluminum sleeve 32 and the steel wire rope, and specifically: the pressure applied by the device to the 8-shaped double-hole aluminum sleeves 32 with the same specification is the same, so that the deformation of each 8-shaped double-hole aluminum sleeve 32 is the same, namely, the 8-shaped double-hole aluminum sleeve 32 and a steel wire rope are firmly connected together, the problem that the connection reliability of the steel wire rope end is affected due to insufficient manual force application is avoided, the connection reliability of the steel wire rope end is greatly improved, and the possibility of accidents is reduced.
The deformation of the 8-shaped double-hole aluminum sleeve 32 can be changed according to actual needs, so that the connection strength of the 8-shaped double-hole aluminum sleeve 32 and a steel wire rope can be changed, and specifically: by pressing the + key or the-key, the controller controls the third driver 8 to rotate forward or backward, thereby adjusting the upper jaw body 3 to move up or down. As shown in fig. 8, when the upper jaw body 3 moves down and the figure-8 double Kong Lvtao is clamped between the upper jaw body 3 and the lower jaw body 3, the deformation amount generated by the first eccentric wheel 13 and the second eccentric wheel 16 pressing the figure-8 double-hole aluminum sleeve 32 is maximized when the upper jaw body 3 is at the position. As shown in fig. 9, when the upper pincer body 3 moves up and keeps a certain distance between the upper pincer body 3 and the 8-shaped double-hole aluminum sleeve 32, and the upper pincer body 3 is at the position, the deformation amount generated by the first eccentric wheel 13 and the second eccentric wheel 16 extruding the 8-shaped double-hole aluminum sleeve 32 is inversely proportional to the distance between the upper pincer body 3 and the 8-shaped double-hole aluminum sleeve 32, and an operator can adaptively adjust the distance according to actual needs to obtain the optimal connection strength between the 8-shaped double-hole aluminum sleeve 32 and the steel wire rope.
In this embodiment, the first driver 15, the second driver 18 and the third driver 8 are all dc motors, and the control module 2 is a PLC controller. The types of the first driver 15, the second driver 18, the third driver 8, the telescopic motor 21, and the PLC controller may be selected to satisfy the above functions, and are not limited to a specific one.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention, and not for limiting the same; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the invention, and are intended to be included within the scope of the appended claims and description.
