[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0027] Please see Figure 1-9 This utility model provides a technical solution: a cable traction ground trench protection device for a mold changing vehicle, including a mold changing vehicle body 1 and a cable trench body 2. A top plate chain 4 covering the top opening of the cable trench body 2 is installed, and the top plate chain 4 can cover along the length of the opening. One end of the mold changing vehicle body 1 is floatingly connected to a frame 12 via a suspension clamping assembly 13. The two ends of the frame 12 are symmetrically equipped with reset wheels 10 for clamping the top plate chain 4 from above to ensure reset after passage. The middle of the frame 12 is symmetrically equipped with guide wheels 11 that guide the top plate chain 4 from below and prevent its deviation.

[0028] One end of the mold changing vehicle body 1 is fixedly connected to a hollow cable traction frame 9, which is used to hold cables. The bottom of the cable traction frame 9 is equipped with a drag chain 5 to constrain the movement trajectory of the cable to avoid cable tangling or wear.

[0029] like Figure 9 As shown: Two connecting plates 3 are symmetrically fixedly connected to one end of the body 1 of the mold changing vehicle for connecting the frame 12 and the cable traction frame 9. The connecting plates 3 are respectively provided with floating connecting holes 6 for cooperating with the suspension clamping assembly 13 to realize the floating connection of the frame 12 and traction frame connecting holes 15 for fixing the cable traction frame 9. The diameter of the floating connecting hole 6 is larger than the diameter of the mating part to allow relative floating.

[0030] like Figure 4 , Figure 5 and Figure 6 As shown: The suspension clamping assembly 13 includes a rod 131. Both ends of the rod 131 are provided with threads for easy installation of nuts. The bottom end of the rod 131 vertically penetrates the plate on the outside of the frame 12 and is fitted with a limiting nut 134 to limit the relative position of the rod 131 and the frame 12. The bottom ends of the four rods 131 are rigidly connected to the mold changing vehicle body 1. The outer spring 132 is used to support the frame 12. Its suspension mechanism meets the requirements for the vertical displacement of the mold changing vehicle body 1.

[0031] like Figure 4 , Figure 5 and Figure 6 As shown: Two limiting plates 133 are symmetrically arranged on the outer side of the rod 131 along the axial direction. A spring 132 providing elastic restoring force is installed between the two limiting plates 133. The spring 132 is coaxially sleeved on the outer side of the rod 131. A clamping nut 135 is installed at the top of the rod 131.

[0032] like Figure 2 and Figure 3 As shown: The cable traction frame 9 passes through the opening of the cable trench body 2. The hollow corners of the cable traction frame 9 are all rounded, used to collect the power lines and control lines of each branch, and finally form a cable group that is inserted into the cable drag chain 5. The top of the cable traction frame 9 is detachably connected to the traction frame connection hole 15 by multiple evenly distributed bolts. The bolt connection method ensures the stable fixation of the cable traction frame 9 to the mold changing vehicle body 1, and facilitates disassembly and maintenance.

[0033] like Figure 2 and Figure 3 As shown: Two switch modules 8 are installed on the inner wall of the cable trench body 2 via an adjustment plate, and the two trigger positions can be adjusted by the adjustment plate.

[0034] A boat-shaped pressure plate 7 is installed on one side of the bottom of the cable traction frame 9 and moves synchronously with it. The shape of the boat-shaped pressure plate 7 is adapted to the trigger end of the switch module 8. When the mold changing vehicle body 1 moves, the boat-shaped pressure plate 7 touches the two switch modules 8 in turn, providing two commands: deceleration and stop.

[0035] like Figure 3 and Figure 4 As shown: the reset wheels 10 are symmetrically distributed at both ends of the frame 12 and the lower edge of the wheel body abuts against the upper surface of the top plate chain 4. The guide wheels 11 are symmetrically distributed in the middle of the frame 12 and the upper edge of the wheel body abuts against the lower surface of the top plate chain 4. The outer circle of the guide wheel 11 is provided with a process groove that matches the shape of the chain link of the top plate chain 4. The top plate chain 4 is accurately guided by the upper and lower parts, so as to avoid it from deviating or getting stuck when the device passes through.

[0036] like Figure 4As shown: Guide wear-resistant blocks 14 are symmetrically installed on the middle of both sides of the frame 12. Their inner edges contact the two side edges of the top plate chain 4 to limit the displacement of the top plate chain 4 to assist in guidance, and reduce wear between devices through wear-resistant properties.

[0037] Working principle: When the mold changing vehicle body 1 moves, it will drive the frame 12 and the cable traction frame 9 to move as well. The frame 12 is floatingly connected to the mold changing vehicle body 1 through the suspension clamping assembly 13, so that the frame 12 can adapt to the slight displacement of the mold changing vehicle body 1, while maintaining stable pressure on the top plate chain 4.

[0038] During the movement of the frame 12, the reset wheels 10 at both ends of the frame 12 press against the top plate chain 4 from above, ensuring that the top plate chain 4 quickly resets and closes after the device passes. The guide wheel 11 in the middle fits against the top plate chain 4 from below, and its outer circular process groove is adapted to the structure of the top plate chain 4. Together with the guide wear-resistant blocks 14 on both sides, it restricts the offset of the top plate chain 4, realizes the precise guidance of the top plate chain 4, and reduces wear.

[0039] The cable traction frame 9 moves synchronously with the main body 1 of the mold changing vehicle. Its hollow structure gathers power lines, control lines, etc. to form a cable group. The bottom drag chain 5 constrains the movement trajectory of the cable to prevent the cable from getting tangled, worn or falling out of the groove.

[0040] When the mold changing vehicle moves to the preset position, the boat-shaped pressure plate 7 at the bottom of the cable traction frame 9 presses the switch module 8, thereby triggering deceleration and stop commands to ensure the safe start and stop of the mold changing vehicle.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
