Description

Technical Field

[0002] In electromechanical installation projects, the precision control of the center of a large-diameter device has always been a difficult problem in equipment installation. At present, a centroid is usually used as a special tool to find the center line of the equipment to assist in the installation of the equipment. It is mainly composed of three parts: a fixed base, a moving block, and a winding device. The winding device includes a hanging wire and a hanging hammer. When in use, the relative position of the hanging wire and the installation reference is measured, and the position of the moving block of the centroid is adjusted to move the hanging wire so that the hanging wire moves to the predetermined center position of the installation reference. Then, the hanging wire is used as a mark line to determine the installation position of other equipment along the axis of the hanging wire to meet the concentricity requirements. However, the current movement of the hanging wire is usually adjusted manually, which not only fails to meet the accuracy requirements, but also has a very low efficiency in obtaining the center of the circle, resulting in a slow progress in the installation of the equipment and reducing the installation efficiency of the equipment. Therefore, it is urgently necessary to provide an electric adjustment centroid that can replace the traditional manual adjustment of the hanging wire position to improve the efficiency and accuracy of obtaining the mark line and improve the efficiency of equipment installation.

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0028] In the present invention, unless otherwise clearly specified and limited, the terms "set", "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection; it can be a mechanical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] like Figure 1 As shown, an electric adjustment centering device includes a support frame 1, a first guide rail 2 is provided on the support frame, and a first guide rail 2 is provided on the support frame. Figure 2 and Figure 3 As shown, the first guide rail includes two parallel and symmetrically distributed guide plates 201, both of which are located below the power drive mechanism, and the vertical cross-section of each guide plate is U-shaped. A first sliding member 3 is horizontally slidably connected to the first guide rail, and a second guide rail 4 perpendicular to the first guide rail is provided on the first sliding member. Figures 6 to 8 As shown, the first sliding member includes an I-shaped plate 301 and two guide members 302. The I-shaped plate is slidably connected to the two guide pieces located on both sides thereof. Slide grooves are provided on both sides of the I-shaped plate, and the two guide pieces are embedded in the slide grooves to cooperate with each other. A mounting hole 303 that runs through the middle of the I-shaped plate and matches the transmission shaft is provided. The transmission shaft passes through the mounting hole and is rotatably connected to the I-shaped plate through a bearing (not shown in the figure). The two guide members are symmetrically connected to the two sides of the lower end of the I-shaped plate, and form a second guide rail with the lower end surface of the I-shaped plate. The vertical cross-section of each guide member is L-shaped, and the two sides of the rectangular frame are respectively slidably matched with the two guide members. A second sliding member 5 is horizontally slidably connected to the second guide rail, and a winding mechanism is connected below the second sliding member. The second sliding member includes a rectangular frame 501 and a U-shaped member 502 connected to the outside of the four top corners of the rectangular frame. The lower end of each U-shaped member is respectively connected to an L-shaped positioning plate 503, and the winding mechanism is connected between the four L-shaped positioning plates. Combined with Fig. 9As shown, a rack 6 parallel to the second guide rail is provided on the inner wall of one side of the rectangular frame, and the rack and the rectangular frame are an integral structure to enhance the connection strength between the two. A transmission shaft 7 is passed through and rotatably connected to the first sliding member, and the upper end of the transmission shaft is connected to a power drive mechanism for driving it to rotate or move along the length direction of the first guide rail, and the lower end of the transmission shaft is connected to a gear 8, and the gear is connected to the rack. In this embodiment, the length direction of the first guide rail is set as the X-axis direction, and the length direction of the second guide rail is set as the Y-axis direction. When the power drive mechanism drives the transmission shaft to rotate, the transmission shaft drives the gear to rotate. Since the gear is meshed with the rack, the rectangular frame is driven to slide horizontally along the second guide rail (Y-axis movement), thereby driving the winding mechanism to move along the Y-axis; when the power drive mechanism drives the transmission shaft to translate along the length direction of the first guide rail, the transmission shaft drives the first sliding member and the gear to move horizontally, and the first sliding member drives the moving frame to slide horizontally along the first guide rail (X-axis movement), thereby driving the winding mechanism to move along the X-axis.

[0030] like Figures 1 to 5 As shown, the power drive mechanism includes a worm wheel 9 connected to the upper end of the transmission shaft, and two parallel worms 10 distributed on both sides of the worm wheel and transmission-connected thereto. The two worms are arranged along the length direction of the first guide rail, and the thread rotation directions of the two worms are opposite. One end of each worm is connected to a drive motor (not shown in the figure), and each drive motor drives the corresponding worm to rotate. When the two worms rotate in the same direction, the worm wheel can be driven to rotate, and the transmission shaft and gear can be driven to rotate because the meshing tooth patterns of the two worms and the worm wheel are in opposite directions; when the two worms rotate in opposite directions, the worm wheel can be driven to move along the length direction of the two worms, thereby driving the transmission shaft and gear to move along the length direction of the two worms (i.e., the length direction of the first guide rail). The two drive motors are used to control the movement of the winding mechanism, thereby replacing the traditional manual adjustment method, effectively improving the efficiency and accuracy of obtaining the marking line (suspension line), and improving the equipment installation efficiency.

[0031] like Figure 1 , Figure 2 and Fig.10 As shown, the winding mechanism includes a support plate 11, a winding motor, a winding shaft 12, a suspension wire 13 and a hanging hammer 14. The four top corners of the support plate are respectively connected to four L-shaped positioning plates. The winding shaft is rotatably installed above the support plate and connected to the winding motor (not shown in the figure). One end of the suspension wire is wound around the winding shaft, and the other end passes through the wire hole provided on the support plate and is connected to the hanging hammer. The winding motor is used to control the release and winding functions of the suspension wire and adjust the height of the hanging hammer.

[0032] The working principle of the utility model is as follows:

[0033] like Figures 1 to 10As shown, the two drive motors connected to the two worms 10 work synchronously. When the output shafts of the two drive motors rotate in the same direction, that is, the two worms 10 rotate in the same direction, because the meshing teeth of the two and the worm wheel 9 are in opposite directions, the worm wheel 9 rotates accordingly, and drives the transmission shaft 7 and the gear 8 to rotate synchronously. Since the gear 8 is meshed with the rack 6 on the rectangular frame 501, the rectangular frame 501 can be driven to slide horizontally along the second guide rail 4, thereby driving the winding mechanism to move along the Y axis; when the output shafts of the two drive motors rotate in opposite directions, that is, the two worms 10 rotate in opposite directions, the worm wheel 9 moves along the length direction of the two worms 10, and drives the transmission shaft 7, the gear 8, and the first sliding member 3 to move along the length direction of the two worms 10, thereby driving the second sliding member 5 and the winding mechanism to move along the X axis. When it is necessary to adjust the height of the hanging hammer 14, the winding motor can be started to control the winding shaft 12 to adjust the winding and unwinding of the hanging wire 13.

[0034] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is limited by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims in the utility model.
