[0033] like Figure 1 As shown, in some embodiments of the present invention, a wire rope sleeve plugging machine 100 is provided, including a hydraulic machine 1 and a plugging machine 2. The hydraulic machine 1 includes a machine body, a hydraulic drive module and a piston 12. The hydraulic drive module is arranged on the machine, and the hydraulic drive module is configured to be controlled to drive the piston plate in the piston 12 to reciprocate in its guide direction. The plugging machine 2 is arranged at one end of the machine away from the hydraulic drive module. The plugging machine 2 includes a pin 21, a foot pedal and a baffle 22. The foot pedal is connected to the hydraulic drive module, and the foot pedal is used to drive the hydraulic drive module to operate; the pin 21 is connected to the piston 12, and a spiral groove is arranged on the pin 21, and the spiral groove is used to install the rope body; the baffle 22 is arranged below the pin 21, and a plugging groove aligned with the pin 21 is arranged on the baffle 22. The pin 21 is controlled to drive the rope body to reciprocate in the vertical direction and cooperate with the plugging groove to complete the plugging operation.

[0034] The machine tool body includes a working platform and supporting legs, and the plugging machine 2 is arranged on the working platform. Specifically, the baffle 22 is placed on the working platform, and the plugging pin 21 is located above the working platform. The supporting legs are used to support the working platform. The hydraulic drive module is partially arranged on the working platform.

[0035] The hydraulic drive module includes a drive motor 15 and a hydraulic press 11. The drive motor 15 is arranged on the working platform. The hydraulic press 11 is located below the working platform and connected to the working platform. The overflow valve 14 is arranged on the working platform.

[0036] The drive motor 15 is connected to the foot pedal, and the drive motor 15 is configured to be controlled to rotate forward or reverse. The hydraulic press 11 is located at one end of the bed, the plug-in machine 2 is located at the other end of the machine tool, and the drive motor 15 is located between the hydraulic press 11 and the plug-in machine 2 on the machine tool. The hydraulic press 11 is connected to the drive motor 15, and the hydraulic press 11 is connected to the piston 12 through a pipeline. The hydraulic press 11 is configured to reduce the pressure in the piston 12 when the drive motor 15 rotates forward, so that the piston rod moves upward. Alternatively, the hydraulic press 11 is configured to increase the pressure in the piston 12 when the motor rotates reversely, so that the piston rod moves downward. The mechanical energy transmitted by the drive motor 15 is converted into the pressure energy of the liquid by the hydraulic press 11, and the liquid is then transported to the piston 12 to drive the piston rod to drive the pin 21 to perform the plugging action.

[0037] It should be noted that the "forward direction" and "reverse direction" in the "forward rotation" and "reverse rotation" described in the present invention can be set according to actual needs. Specifically, the "forward direction" can be clockwise or counterclockwise, and the "reverse direction" is the opposite direction of the "forward direction".

[0038] A support frame is provided on the machine tool, and the support frame is used to install the piston 12. The piston 12 includes a piston body and a piston plate. The piston body has a accommodating space. The piston plate is arranged in the piston body to divide the accommodating space into a first accommodating chamber and a second accommodating chamber. The piston body includes a hydraulic hole and a piston hole. The hydraulic hole is located in the first accommodating chamber. The hydraulic hole is used to connect with the hydraulic press 11 through a pipeline, so that the hydraulic press 11 can fill liquid into the first accommodating space through the hydraulic hole. The piston hole is located in the second accommodating chamber. The piston hole allows one end of the piston rod to pass through, and the other end of the piston rod is clamped with the inner side of the piston hole. After the hydraulic plate is squeezed by the liquid in the first accommodating chamber, the piston rod is driven to reciprocate in the piston hole to drive the pin 21 to perform the plug-in action.

[0039] The pedal is connected to the drive motor 15. The pedal includes a left pedal and a right pedal. The left pedal is forced to drive the drive motor 15 to rotate forward; the right pedal is forced to drive the drive motor 15 to rotate reversely. The operator steps on the left and right pedals to make the pin 21 complete the upward and downward plugging actions.

[0040] The hydraulic drive module also includes a dynamic contactor, and the left foot pedal, the right foot pedal and the drive motor 15 are all connected to the dynamic contactor. When any one of the left foot pedal and the right foot pedal is stressed, the dynamic and static contactor contacts are closed, and the drive motor 15 is powered on. When any one of the left foot pedal and the right foot pedal is released from the stress state, the dynamic and static contactor contacts are disconnected, and the drive motor 15 is powered off.

[0041] The plugging machine 2 also includes a fixed sleeve, which is arranged at the end of the piston rod and is used to sleeve the plug pin 21. Specifically, one end of the fixed sleeve is sleeved on the piston rod of the piston 12, and the other end of the fixed sleeve is sleeved on the handle end of the plug pin 21.

[0042] The hydraulic drive module also includes a rotary valve handle 13 , which is disposed on a pipeline between the hydraulic press 11 and the piston 12 . The rotary valve handle 13 can control the connection / interruption between the hydraulic press 11 and the piston 12 or control the opening of the pipeline between the hydraulic press 11 and the piston 12 .

[0043] In order to prevent the piston 12 from being unable to operate normally due to excessive pressure in the hydraulic press 11 during long-term operation, the hydraulic drive module of the present invention also includes a relief valve 14, which is connected to the hydraulic press 11. The relief valve 14 is used to release pressure when the pressure of the hydraulic press 11 exceeds the maximum limit, so as to ensure safe operation during the entire operation process.

[0044] The machine tool also includes a guide rod disposed on the plugging machine 2, which is located on one side of the baffle 22 and is used to cooperate with the plug pin 21 to wind the end of the wire rope into a set. Specifically, when the operator steps on the pedal to make the piston 12 reciprocate and drive the plug pin 21 to move up and down, the plugging action is performed by plugging the plug pin 21 with the baffle 22, and the rope body is wound along the guide rod, so that the end of the wire rope is set and the plugging action continues.

[0045] Among them, one end of the guide rod is arranged parallel to the insertion pin 21, and the other end of the guide rod is bent toward the position of the insertion pin 21. The operator can wrap the rope body around the bent section to wrap the rope body into a sleeve.

[0046] The baffle 22 is located 1.8 to 2.2 mm below the end of the pin 21 .

[0047] The plug-in slot is set as a "V"-shaped slot.

[0048] In some other embodiments of the present invention, a wire rope sleeve splicing method is provided, including the wire rope sleeve splicing machine tool 100 described above, and the splicing method includes:

[0049] Step S110, selecting the model of the plug pin 21 according to the diameter of the cable body to be plugged, and installing the plug pin 21 on the machine tool.

[0050] Generally, the pin 21 has five models to choose from, which can meet the needs of steel wire ropes with diameters ranging from 10mm to 32mm. Specifically, it includes: No. 1 pin 21, which can be used to splice steel wire ropes with diameters ranging from 10mm to 12.5mm; No. 2 pin 21, which can be used to splice steel wire ropes with diameters ranging from 13mm to 15.5mm; No. 3 pin 21, which can be used to splice steel wire ropes with diameters ranging from 15.5mm to 21.5mm; No. 4 pin 21, which can be used to splice steel wire ropes with diameters ranging from 24mm to 28mm; and No. 5 pin 21, which can be used to splice steel wire ropes with diameters ranging from 26mm to 32mm.

[0051] Step S120, assemble the piston 12, install the pin 21 on the piston rod, adjust the position of the piston 12 so that the pin 21 is aligned with the plug slot, and connect the piston 12 to the hydraulic press 11. Specifically, after selecting the model of the pin 21, start assembling the piston 12, pass one end of the piston rod through the piston hole, place the piston plate in the piston body, move the piston 12 placed on the support frame, align the pin 21 with the plug slot, connect the hydraulic press 11 to the hydraulic hole pipeline, and then the assembly is completed.

[0052] Step S130, turn the rotary valve handle 13 to control the hydraulic press 11 to pass liquid into the piston 12, so that the distance between the end of the pin 21 and the baffle 22 is within the preset distance range. Before fixing the rope body to the pin 21, it is necessary to adjust the baffle 22 and the plug-in position. By adjusting the opening of the rotary valve handle 13, the hydraulic press 11 is controlled to pass liquid into the piston 12 to adjust the distance of the piston plate, so that the distance between the end of the pin 21 and the baffle 22 is within the preset distance range. It should be noted that the gap between the pin 21 and the baffle 22 cannot be too large. If the gap is too large, the pin 21 cannot be accurately inserted into the wire rope sleeve when it goes down or up during the wire rope sleeve plug-in process, causing the wire rope sleeve to be plugged in loosely and the plug-in finished product to be unqualified. Therefore, in the present invention, the gap between the pin 21 and the baffle 22 is set to 1.8mm to 2.2mm, that is, the preset distance range is set to 1.8mm to 2.2mm. In some more specific embodiments of the present invention, the gap between the pin 21 and the baffle 22 is set to 2 mm.

[0053] Step S140, install one end of the wire rope on the inserted pin 21, adjust the rotary valve handle 13, and adjust the flow of the hydraulic press 11 to a preset flow value. Start the motor, step on the pedal, and start plugging according to the 2-4 plug-in method or the 3-2-1 plug-in method. The preset flow value can be obtained based on the operator's experience.

[0054] The present invention takes the two-four plug-in method as an example, and the specific plug-in steps are:

[0055] The operator steps on the left pedal with his foot to make the tip of the pin 21 slowly enter the spiral groove of the wire rope. At the same time, the operator rotates the rope with his left hand to make the rope appear as a two-strand and four-strand split state. That is, there are two strands of rope in front of the pin 21 and four strands of rope behind the pin 21. After the rope is split into two and four strands, the pin 21 stops and the wire rope is wrapped around the guide rod to form a set. The first strand of the rope head to be braided is separated and placed in the oblique groove of the pin 21, and the remaining five strands are placed behind the pin 21. The operator steps on the left pedal again to make the pin 21 move downward, so that the oblique groove on the pin 21 slowly passes through the gap between the two and four strands. Figure 2 After inserting 24 stitches in the order shown, insert 1 stitch every other strand, and then insert 3 stitches every other strand. The whole rope loop has a total of 27 stitches.

[0056] Step S150, after the splicing is completed, the spliced ​​end of the wire rope is removed, and the unspliced ​​end of the wire rope is spliced ​​according to steps S120 to S140.

[0057] Step S160, after both ends of the wire rope are connected, the rope body is removed, and the state of the rotary valve handle 13 is switched to the closed state, and the drive motor 15 and the hydraulic press 11 are turned off at the same time, and the connection operation is completed.

[0058] In some further embodiments of the present invention, the splicing method further includes a shaping step at the splicing site. Specifically, during the splicing process, when burrs appear on the wire rope loop or the splicing is not tight, the bevel slot of the pin 21 can be unloaded, and the operator can step on a foot switch to move the pin 21 up and down, and use the flat end of the pin 21 to squeeze and shape the burrs and the loose parts of the rope loop.

[0059] Those skilled in the art can understand that the present invention connects the foot pedal to the hydraulic drive module and the pin 21 to the piston rod, so that the operator can drive the pin 21 to complete the plugging action by stepping on the foot pedal; at the same time, an inclined groove for placing the strands of the wire rope is provided on the pin 21, and a plugging groove aligned with the pin 21 is provided on the baffle 22, so that the pin 21 drives the wire rope to cooperate with the plugging groove to complete the plugging operation. The plugging machine 100 of the present invention effectively reduces the difficulty of manually inserting the wire rope sleeve, avoids the breakage and wear of the wire rope during the manual plugging process, shortens the plugging time, improves the plugging quality, reduces the labor intensity, and eliminates the damage to the human body caused by the breakage of the wire rope during the plugging process.

[0060] Furthermore, the splicing machine 100 of the present invention can splice different types of steel wire ropes and can be applied to a variety of industries, such as the power industry, the communications industry, and tower crane climbing, etc., and the device has stable performance, is easy to use, has a low cost, a simple structure, and is relatively easy to implement.

[0061] So far, the technical solution of the present invention has been described in combination with the above multiple embodiments, but it is easy for those skilled in the art to understand that the protection scope of the present invention is not limited to these specific embodiments. Without departing from the technical principles of the present invention, those skilled in the art can split and combine the technical solutions in the above embodiments, and can also make equivalent changes or replacements to the relevant technical features.
