Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of long shaft couplings, specifically relating to a coupling alignment and positioning rotary bracket. Background Technology
[0002] In the steel industry, 90% of the motor-driven equipment is connected to the equipment via couplings. Couplings come in various forms, including diaphragm, pin, and star-shaped couplings. Based on shaft spacing, they can be categorized as short (<1m), medium (<1-5m), and long (>5m). Alignment of long-spacing couplings is relatively difficult, primarily due to their length and weight, which causes sagging under gravity. Normally, dial gauges are used for alignment (see Chinese patent document CN110472329A (201910747334.8)). This method is wasteful of manpower and resources, and inefficient and slow. Therefore, a more efficient alignment method and tool are essential. Utility Model Content
[0003] The main purpose of this utility model is to provide a coupling alignment and positioning rotary bracket. The upper ends of the first and second rotary support rods form a cylindrical rotary support part to support one end of the intermediate extended shaft. Since the first and second rotary support rods are linearly slidable on the vertical sliding surface of the support plate, after one end of the intermediate extended shaft is coaxially fixedly connected to the connecting component, the vertical and horizontal positions of the other end of the intermediate extended shaft supported by the coupling alignment and positioning rotary bracket can be adjusted using the first and second rotary support rods. This eliminates the axial misalignment caused by the sagging and shaking of the intermediate extended shaft of the long shaft coupling, greatly improving work efficiency. This fixture is applicable to the alignment and installation of various long shaft couplings and has the advantages of convenient operation, high efficiency, and long service life.
[0004] The technical problem to be solved by this utility model is achieved by the following technical solution: a coupling alignment and positioning rotary bracket, including a fixed base, a support plate, a first rotary support rod, a second rotary support rod and a base adjustment bolt; The support plate is vertically mounted on the fixed base. The support plate is provided with a vertical sliding surface. The first rotating support rod and the second rotating support rod are linearly slidable on the vertical sliding surface. The first rotating support rod and the second rotating support rod are inclinedly mounted on the vertical sliding surface. The fixed base is provided with a fixing hole, and the base adjustment bolt is set in the fixing hole; The extensions of the axes of the first and second rotating support rods intersect obliquely upwards, and the upper ends of the first and second rotating support rods form a cylindrical rotating support portion.
[0005] In a preferred embodiment of this invention, the support plate is provided with an upward-opening V-shaped groove; The first and second rotary support rods are symmetrically arranged on both sides of the V-shaped groove. The upper surfaces of the first and second rotary support rods are positioned higher than the inner wall of the V-groove. The V-groove allows for pre-support of the intermediate extended shaft of the coupling and enables coarse adjustment of its axis, thus improving the efficiency of fine-tuning the first and second rotary support rods.
[0006] Preferably, this utility model also includes a rotating support wheel; The rotating support wheel is rotatably mounted on the upper end of the first rotating support rod and the second rotating support rod via a rotating shaft; The rotating support wheels are located on the sides of the first and second rotating support rods, respectively. These rotating support wheels reduce the friction of the intermediate extended shaft of the coupling during rolling.
[0007] In a preferred embodiment of this invention, the rotating support wheel is a bearing or a rubber wheel.
[0008] Preferably, in this invention, the axes of the first rotating support rod and the second rotating support rod are perpendicular to the side wall of the V-shaped groove.
[0009] Preferably, the first and second rotating support rods are each provided with a scale along the axial direction. By providing scales on the first and second rotating support rods, the adjustment length at the upper end of the first and second rotating support rods can be displayed intuitively, improving the accuracy of adjusting the position of the intermediate extension shaft axis.
[0010] Preferably, this utility model also includes a height adjustment plate, and one or more of the height adjustment plates are disposed below the fixed base; The height adjustment plate is provided with bolt through holes, through which the base adjustment bolts pass. By setting the height adjustment plate, the overall height of the coupling alignment and positioning rotary support can be quickly adjusted, avoiding the situation where the height adjustment range of the first and second rotary support rods is too small, making them unsuitable for couplings with high axis positions.
[0011] Preferably, in this invention, the first and second rotating support rods have elongated adjustment holes along their axial direction in the middle. The support plate has two rows of bolt connection holes arranged linearly. The adjustment holes are connected to the two bolt connection holes by fasteners. By installing two bolts within the elongated adjustment holes, the first and second rotating support rods can move linearly along their respective axial directions, thereby enabling fine-tuning of the axial height and horizontal direction of the extended shaft of the upper support.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: The coupling alignment and positioning rotary bracket of this utility model includes a fixed base, a support plate, a first rotary support rod, a second rotary support rod, and a base adjusting bolt; the support plate is vertically set on the fixed base, and the support plate is provided with a vertical sliding surface; the first rotary support rod and the second rotary support rod are linearly slidable on the vertical sliding surface, and the first rotary support rod and the second rotary support rod are inclinedly set on the vertical sliding surface; the extension lines of the axes of the first rotary support rod and the second rotary support rod intersect obliquely upwards, and the upper ends of the first rotary support rod and the upper ends of the second rotary support rod form a cylindrical rotary support part. By mounting the intermediate extended shaft on the upper ends of the first rotary support rod and the second rotary support rod, the rotation of the coupling can be realized. Then, by controlling the linear sliding of the first rotary support rod and the second rotary support rod, the position of the axis of one end of the intermediate extended shaft along the vertical and horizontal directions can be adjusted, thereby eliminating the axial offset caused by the sagging and shaking of the intermediate extended shaft of the long shaft coupling, so that the axis of the intermediate extended shaft is located on the same straight line.
[0013] The fixed base of this utility model is provided with a fixing hole, and the base adjustment bolt is set in the fixing hole. The relative position of the coupling alignment and positioning rotating bracket and the coupling can be adjusted according to the site conditions, making it more versatile.

[0026] The rotating support wheels 6 are bearings or rubber wheels.
[0027] The axes of the first rotating support rod 3 and the second rotating support rod 4 are perpendicular to the side walls of the V-shaped groove 22. The first rotating support rod 3 and the second rotating support rod 4 are respectively provided with scales along the axial direction.
[0028] The shaft coupling alignment positioning rotating support further comprises height adjustment plates 7, and one or more than one height adjustment plate 7 is arranged below the fixed base 1.
