Technical Field
[0001] The utility model relates to the technical field of production of roller flaw detection equipment, and more specifically, to a hydraulic lifting device for a ferrule UT detection platform. Background Art
[0002] For ferrule immersion ultrasonic flaw detection, the entire mechanism must be immersed in water, which is very inconvenient for manual loading and unloading. Currently, a motor is usually used to drive the screw to lift and lower the detection platform. However, during the screw lifting process, the copper nut wears very seriously and has a short life, resulting in high after-sales maintenance costs. Utility Model Content
[0003] In order to overcome the above-mentioned defects of the prior art, an embodiment of the utility model provides a hydraulic lifting device for a ferrule UT detection platform.
[0004] To achieve the above-mentioned purpose, the utility model provides a hydraulic lifting device for a UT detection platform of a ring, whose structure includes two relatively arranged support plates, and a lifting platform that can be lifted up and down is provided between the two support plates. The innovation point is that: a mounting groove perpendicular to the horizontal plane is provided at the center position of the support plate, a hydraulic cylinder is provided inside the mounting groove, a hinge shaft is provided at the output end of the hydraulic cylinder, symmetrical fixing plates are provided at both ends of the lifting platform, hinge grooves are provided on the fixing plates, and the hinge shaft is hingedly connected to the inside of the hinge grooves, and two mutually parallel clamps are provided at both ends of the lifting platform, the clamps are slidably installed on the support plates, and the central axis of rotation of the hinge shaft is parallel to the clamps.
[0005] Furthermore, the lifting platform is provided with a rope encoder, the hydraulic cylinder is provided with a controller, and the controller and the rope encoder are electrically connected.
[0006] Furthermore, both upper and lower ends of the clamping plate are provided with rotatable first rollers, and the first rollers are rotatably arranged on the surface of the supporting plate.
[0007] Furthermore, a side plate is provided on the side of the clamping plate, and a rotatable second roller is provided at both upper and lower ends of the side plate, and the second roller is rotatably arranged on the side of the supporting plate.
[0008] The technical effects and advantages of the utility model: the utility model does not need to use nuts, thus avoiding the nuts from rusting in water and reducing after-sales maintenance. At the same time, through the hinge shaft and the hinge groove, the lifting platform can swing at the output end of the hydraulic cylinder, and this swinging makes it convenient to slide the splint onto the support plate. BRIEF DESCRIPTION OF THE DRAWINGS
[0009] Figure 1 It is an isometric drawing of the present utility model.
[0010] Figure 2It is an enlarged view of part A of the utility model. DETAILED DESCRIPTION
[0011] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0012] like Figure 1 to Figure 2 This is a specific implementation of the utility model, and its structure includes two relatively arranged support plates 1, a lifting platform 11 that can be lifted up and down is provided between the two support plates 1, a mounting groove 12 perpendicular to the horizontal plane is provided at the center position of the support plate 1, a hydraulic cylinder 13 is provided inside the mounting groove 12, and a hinge shaft 14 is provided at the output end of the hydraulic cylinder 13, symmetrical fixing plates 15 are provided at both ends of the lifting platform 11, hinge grooves 16 are provided on the fixing plates 15, and the hinge shaft 14 is hingedly connected to the inside of the hinge grooves 16, and two mutually parallel clamps 17 are provided at both ends of the lifting platform 11, and the clamps 17 are slidably installed on the support plates 1, and the central axis of rotation of the hinge shaft 14 is parallel to the clamps 17.
[0013] In the utility model, the lifting and lowering of the lifting platform 11 is driven by two hydraulic cylinders 13, which act synchronously on the two ends of the lifting platform 11, thereby driving the lifting platform 11 to move up and down. Compared with the screw rod, the utility model does not need to use nuts, which avoids the nuts from rusting in water and reduces after-sales maintenance. At the same time, through the hinge shaft 14 and the hinge groove 16, the lifting platform 11 can swing at the output end of the hydraulic cylinder 13, and this swing makes it convenient to slide the clamping plate 17 on the support plate 1.
[0014] In the present utility model, as a preferred solution, a draw-rope encoder is provided on the lifting platform 11, and a controller is provided on the hydraulic cylinder 13, and the controller and the draw-rope encoder are electrically connected.
[0015] In the present invention, the rope encoder can detect the distance that the lifting platform 11 moves up and down, and control the position of the lifting platform 11 when it moves up and down by transmitting the signal to the controller.
[0016] In the present invention, as a preferred solution, both upper and lower ends of the clamping plate 17 are provided with rotatable first rollers 2 , and the first rollers 2 are rotatably arranged on the surface of the supporting plate 1 .
[0017] In the present invention, as a preferred solution, a side plate 21 is provided on the side of the clamping plate 17 , and a rotatable second roller 22 is provided at both upper and lower ends of the side plate 21 , and the second roller 22 is rotatably arranged on the side of the support plate 1 .
[0018] In the utility model, the first roller 2 and the second roller 22 are respectively in contact with the surface and the side of the support plate 1. As the lifting platform 11 moves up and down, the second roller 22 and the second roller 22 roll on the two surfaces of the support plate 1, which can guide the up and down movement of the lifting platform 11. Secondly, during installation, by swinging the position of the lifting platform 11, the first roller 2 and the second roller 22 can be conveniently attached to the surface and the side of the support plate 1 respectively.
[0019] Finally, a few points should be explained: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, which may refer to mechanical connection or electrical connection, or internal communication between two components, or direct connection.
