Description

Technical Field

[0001] This utility model relates to the field of pipeline welding technology, specifically to a cable interface protection device for ductile iron pipeline welding machines. Background Technology

[0002] During the casting process of ductile iron pipes, small holes are drilled in the sand core of the socket plug to create impact points on the end face of the cast pipe socket. In the subsequent cement coating process, cement is injected into the rapidly centrifugally rotating cast iron pipe, and the cement covers the inner wall of the pipe under the action of centrifugal force. The presence of impact points causes the cast iron pipe to vibrate violently during centrifugal rotation. The resulting vibration force allows the cement to adhere better and more evenly to the inner wall of the pipe, effectively reducing the occurrence of quality accidents caused by subsequent cement lining detachment.

[0003] Poorly drilled sand cores, inadequate casting, or collisions during the transport of cast iron pipes can all cause impact points to detach before reaching the cement coating process. Therefore, these damaged sections must be welded before the coating, and the impact points manually repaired. During on-site welding, the frequent pulling of the cable can easily loosen the quick-connect plug at the cable interface, and damage the plastic sheath at the plug's end, causing abnormal welding machine operation and posing safety hazards.

[0004] In view of the above-mentioned defects, the creator of this utility model has finally obtained this utility model after a long period of research and practice. Utility Model Content

Detailed Implementation

[0022] The above-mentioned and other technical features and advantages of this utility model will be described in more detail below with reference to the accompanying drawings.

[0023] Example 1

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, Figure 1 This is a front view of the structure of the cable interface protection device for the ductile iron pipe welding machine; Figure 2 This is a top view of the structure of the cable interface protection device for the ductile iron pipe welding machine; Figure 3 This is a structural side view of the cable interface protection device for the ductile iron pipe welding machine.

[0025] The ductile iron pipe welding machine cable interface protection device of this utility model includes a first connecting part 1 and a second connecting part 2. The first connecting part 1 and the second connecting part 2 are fixedly connected. The first connecting part 1 is detachably connected to the welding machine cable interface, and the second connecting part 2 is detachably connected to the cable quick plug. This can fix the relative position between the welding machine cable interface and the cable quick plug, and prevent the welding machine cable interface and the cable quick plug from separating during repeated pulling of the cable.

[0026] Specifically, the first connecting part 1 includes a base 11 and a pressure plate 12. Both the base 11 and the pressure plate 12 are configured as semi-circular ring structures. The base 11 and the pressure plate 12 are coaxially arranged, and one end of the base 11 and the pressure plate 12 are connected by a first connecting component 13, while the other end of the base 11 and the pressure plate 12 are connected by a second connecting component 14. Thus, the base 11 and the pressure plate 12 can be combined into a circular ring structure. The second connecting part 2 is fixedly disposed on the base 11. By symmetrically arranging the base 11 and the pressure plate 12 on the outer protrusion of the welding machine cable interface, and by fixing the base 11 and the pressure plate 12 together through the first connecting component 13 and the second connecting component 14 to clamp and fix the welding machine cable interface, the first connecting part 1 is detachably connected to the welding machine cable interface.

[0027] The second connecting part 2 includes a fixing plate 21 and a strap. The fixing plate 21 extends in a straight line parallel to the axis of the base 11. The fixing plate 21 is provided with a fitting groove 22, which extends along the direction of the fixing plate 21. The cable quick plug or cable is placed in the fitting groove 22, and the cable quick plug or cable is tied to the fixing plate 21 by the strap, thereby realizing the detachable connection of the second connecting part 2 to the cable quick plug.

[0028] Preferably, the cross-section of the fitting groove 22 is arc-shaped, which facilitates the fitting of the fitting groove 22 with the cable quick plug. Generally, the axis of the fitting groove 22 is consistent with the axis of the base 11, thereby ensuring that after the first connecting part 1 and the second connecting part 2 are respectively connected and fixed to the welding machine cable interface and the cable quick plug, the welding machine cable interface and the cable quick plug are coaxial.

[0029] The length of the fixing plate 21 is generally longer than that of the cable quick plug, thereby protecting the plastic cover at the tail of the cable quick plug from damage by force.

[0030] Preferably, a flexible bonding layer 15 is provided on the inner ring surface of the base 11 and the pressure plate 12, as well as on the groove wall of the bonding groove 22. The flexible bonding layer 15 is made of rubber, thereby ensuring flexible bonding between the welding machine cable interface and the cable quick plug, while increasing the contact area to reduce the relative movement between the first connection and the welding machine cable interface, and between the second connection part 2 and the cable quick plug, thus ensuring the stable position of the welding machine cable interface and the cable quick plug in this utility model.

[0031] This utility model has a compact structure and is easy to install. During the daily use of the welding machine by the operator, it firmly protects the cable quick plug from loosening, ensuring that the welding machine can work normally for a long time and protecting the personal safety of the welding machine operator.

[0032] Example 2

[0033] The first connecting component 13 is configured as a hinge, and the base 11 and the pressure plate 12 are rotatably connected by the hinge, thereby enabling the base 11 and the pressure plate 12 to open and close.

[0034] like Figure 4 As shown, Figure 4 The first connecting component is shown in the structural view. In another embodiment, the first connecting component 13 includes two fixed connecting blocks 131, which are respectively disposed at the ends of the base 11 and the pressure plate 12. Each of the two fixed connecting blocks 131 is provided with a fixed connecting hole. The fixed connecting holes on the two fixed connecting blocks 131 are one-to-one and coaxially arranged. A connecting shaft 132 is disposed in the two corresponding fixed connecting holes. Limiting rings 133 are respectively provided at both ends of the connecting shaft 132. The two fixed connecting blocks 131 are disposed between the two limiting rings 133.

[0035] By connecting in this way, the base 11 and the pressure plate 12 can be pulled apart along the connecting shaft 132, thereby increasing the distance between the base 11 and the pressure plate 12 to allow for the installation of the welding machine cable interface.

[0036] The second connecting assembly 14 includes two movable connecting blocks 141, which are respectively disposed at the ends of the base 11 and the pressure plate 12. The two movable connecting blocks 141 are respectively provided with a first clamping connecting hole 142 and a second clamping connecting hole 143. The first clamping connecting hole 142 and the second clamping connecting hole 143 are coaxially arranged in a one-to-one correspondence. The first clamping connecting hole 142 is a through hole, and the second clamping connecting hole 143 is a threaded hole. The clamping screw 144 passes through the first clamping connecting hole 142 and is threadedly connected to the second clamping connecting hole 143, thereby realizing the fixed connection of the second connecting assembly 14 to the ends of the base 11 and the pressure plate 12.

[0037] Preferably, the clamping screw 144 is also fitted with an anti-loosening washer to ensure the stability of the connection state of the second connecting assembly 14.

[0038] Preferably, the fixing plate 21 is provided with limiting grooves 23, and the limiting grooves 23 are symmetrically arranged on both sides of the fitting groove 22. The binding strap after binding is placed in the limiting grooves 23 to prevent the binding strap from moving axially and improve the fixing connection effect of the binding strap.

[0039] Generally, the cross-section of the limiting groove 23 is set as a triangle, and the bottom of the limiting groove 23, which is set at an inclination, is more convenient for the circumferential binding and fixing of the strap.

[0040] The above description is merely a preferred embodiment of the present utility model and is illustrative rather than restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present utility model, all of which will fall within the protection scope of the present utility model.
