Description

Technical Field

[0001] This utility model relates to the technical field of insulator production equipment, and in particular to a novel hollow composite insulator mold support device. Background Technology

[0002] Hollow composite insulators are special insulating components used in overhead transmission lines and substations. This product consists of a resin-impregnated fiber insulating tube and a silicone rubber shed. The insulating tube bears the mechanical load, while the shed provides protection. They are mainly used in ultra-high voltage transmission projects and equipment such as circuit breakers and surge arresters. Due to various factors such as different application scenarios, uses, and customer requirements, hollow composite insulators come in various shapes and structures. Typically, hollow composite insulators are produced using molds and core molds. The core mold prevents damage to the insulating tube during silicone rubber injection. During production, the core mold is usually placed on a mold support frame, which holds tooling to support the product to be vulcanized. Moving the mold support frame pushes the core mold and the product into the mold. However, the tooling on the existing support frame is not adjustable in center, making it difficult to align with the center of the mold cavity during movement, which can easily cause scratches on the surface of the insulating tube.

[0017] A novel hollow composite insulator support device, such as Figure 1 and Figure 2As shown, it includes: a moving part, an adjusting part, and a support template 8. The moving part can move linearly along the length of the support template 1. The support template 1 is an existing device. The adjusting part is used to adjust the position of the support template 8 in the width direction of the support template 1. The adjusting part includes: a fixed plate 6, two lead screws 7, and two sets of locking nut assemblies. The fixed plate 6 is fixedly connected to the moving part. The two lead screws 7 are arranged in parallel and fixed on the fixed plate 6. The lead screws 7 are arranged along the width direction of the support template 1 and pass through the support template 8. The two sets of locking nut assemblies are respectively provided on the two lead screws 7. Each set of locking nut assemblies includes at least two locking nuts 9. The at least two locking nuts 9 are threadedly connected to the lead screws 7 and arranged on both sides of the support template 8. This application adjusts the position of the support template 8 in the width direction of the mold support frame 1 by setting an adjustment component. Specifically, the locking nut 9 on one side of the support template 8 is loosened, and the support template 8 is dragged along one direction of the two screws 7 until the position of the support template 8 is aligned with the center of the mold cavity. Then, the locking nuts 9 on both sides of the support template 8 are tightened to press the end face of the support template 8 and prevent the position of the support template 8 from changing. When it is necessary to adjust in the other direction, the locking nut 9 on the other side of the support template 8 is loosened for adjustment and then locked. By adjusting the position of the support template 8, this application ensures that the support template can be adjusted to be aligned with the center of the mold cavity for different products or changes in position after use, thereby avoiding scratches on the insulating tube, improving the safety factor, and improving production efficiency.

[0018] Preferably, the moving parts include two sets of pulleys that move along two tracks of the mold support frame 1; there are two fixed plates 6, which are respectively fixed on the two sets of pulleys, and the two ends of the lead screw 7 are respectively fixed on the two fixed plates 6.

[0019] Preferably, the trolley includes a support plate 5 and at least two sliding rollers 2, which are rotatably connected to the support plate 5. A fixing plate 6 is fixedly mounted on the support plate 5 to achieve a fixed connection between the fixing plate 6 and the moving parts. In this embodiment, a set of trolleys is equipped with two sliding rollers 2. The movement of the entire trolley is achieved by the sliding rollers 2 rolling on two tracks of the mold support frame 1, so as to facilitate dragging by the operator.

[0020] Preferably, the trolley also includes a protective cover 3, with at least two sliding rollers 2 disposed inside the protective cover 3. The protective cover 3 is a box with an opening at the bottom. The sliding rollers 2 are arranged along the length of the protective cover 3. The two sides of the protective cover 3 extend below the two tracks of the mold support frame 1 to cover the sliding rollers 2. There are clearance notches at the front and rear ends of the protective cover 3 to allow the two tracks of the mold support frame 1 to pass through, so as to avoid interference during movement. In this way, the protective cover 3 covers the two sliding rollers 2 for protection to prevent pinching.

[0021] Specifically, the protective cover 3 is made of welded steel plate to prevent deformation when pushed; and handles are welded to the front and rear ends or the outside of the protective cover 3 to facilitate the operator to grasp and apply force.

[0022] Preferably, the trolley also includes multiple roller shafts 4, the number of which is the same as the number of sliding rollers 2. One end of each roller shaft 4 is fixed to one side wall of the protective cover 3, and the other end passes through the sliding rollers 2 and the other side wall of the protective cover 3 before being fixed to the support plate 5. The roller shafts 4 connect the sliding rollers 2, the support plate 5, and the protective cover 3 into a whole, ensuring that they move together.

[0023] Specifically, a bearing is installed in the middle of the sliding roller 2, and the roller shaft 4 passes through the bearing to realize the rotation of the sliding roller 2 relative to the roller shaft 4. Then, after pushing the protective cover 3 to move the roller shaft 4, the sliding roller 2 can roll along the track of the mold support frame 1.

[0024] Specifically, a blind hole is provided on the side of the support plate 5, one end of the roller shaft 4 is inserted into the blind hole, and a first threaded hole communicating with the blind hole is provided on the upper surface of the support plate 5. The first fixing screw is tightened in the first threaded hole and pressed against the groove at the end of the roller shaft 4.

[0025] Specifically, the fixing plate 6 is fixed to the upper surface of the support plate 5 by screws. Two parallel first through holes are opened on the side of the fixing plate 6, and the ends of the two lead screws 7 are respectively inserted into the two first through holes. Two second threaded holes are opened on the upper surface of the fixing plate 6, each connecting to one of the two first through holes. Two second through holes are opened on the lower surface of the fixing plate 6, each connecting to one of the two first through holes. The second through holes and second threaded holes are coaxially arranged. Two third threaded holes are opened on the lower surface of the support plate 5, each corresponding to one of the second through holes. A second fixing screw is tightened in the second threaded hole and presses against the upper groove at the end of the lead screw 7. A third fixing screw is tightened in the third threaded hole and passes through the second through hole, pressing against the lower groove at the end of the lead screw 7. Through the cooperation of the second and third fixing screws, the height of the end of the lead screw 7 can be adjusted, thereby keeping the lead screw 7 horizontal. When adjustment is needed, the screws fixing the fixing plate 6 are loosened, the second and third fixing screws are adjusted to bring the end of the lead screw 7 to the appropriate position, and then the screws fixing the fixing plate 6 are tightened to fix it.

[0026] The working principle of this device is as follows:

[0027] Adjust the locking nuts 9 on both sides of the support template 8 to position the support template 8 at the center of the screw 7. Tighten the fixing plate 6 and the support plate 5 with screws. Place the hollow composite insulation tube to be vulcanized on the support template 8 and manually push the protective cover 3. To ensure smoother movement of the support template 8, push the protective covers 3 of the two trolleys simultaneously. The protective cover 3 drives the roller shaft 4, the roller shaft 4 drives the support plate 5, the support plate 5 drives the fixing plate 6 and the screw 7, the screw 7 drives the support template 8 to move, and the support template 8 drives the entire hollow composite insulation tube to be vulcanized to move.
