Description

Technical Field

[0001] This invention relates to the field of auxiliary equipment technology for steel rolling measuring instruments, specifically to a rotating bracket for steel rolling measuring instruments and its usage method. Background Technology

[0002] A measuring instrument is an instrument that can measure the temperature of an object. It consists of a sensor, a transmitter, and a detection element and display device. In a steel rolling production line, in order to control parameters such as the running speed, bandwidth, and temperature of the strip, it is generally necessary to use some measuring instruments to measure the running strip online. To facilitate the testing of the measuring instruments, they are usually mounted on a bracket.

[0003] Existing rotating brackets for rolling mill measuring instruments work by fixing the measuring instrument to a rotating mechanism on the bracket, which then adjusts the instrument's detection angle and orientation. While this method achieves rotational adjustment, it only detects one aspect of the rolling mill, creating a blind spot and preventing comprehensive measurement. Furthermore, existing rotating brackets require a telescopic rod for height adjustment. This involves pulling the movable part of the rod, securing it at the desired height, and then using a limit bolt. This method is cumbersome, requiring operators to overcome the weight of the rotating mechanism and risk hand injuries, resulting in poor flexibility and adjustment performance. Therefore, a new rotating bracket for rolling mill measuring instruments is urgently needed to address these issues. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a rotating bracket for steel rolling measuring instruments and its usage method, enabling comprehensive testing of rolled steel.

[0005] This invention is achieved through the following technical solution: a rotating bracket for a steel rolling measuring instrument is provided, comprising a bearing base, two bearing rods mounted on the bearing base, and a gear ring located between the two bearing rods. The axis of the gear ring extends laterally, and a plurality of instrument mounting plates distributed circumferentially are fixed on the inner wall of the gear ring. Limiting grooves extending circumferentially are respectively provided on the two end faces of the gear ring. Limiting seats are respectively fixed on the upper ends of the two bearing rods, and limiting blocks extending into the limiting grooves are fixed on the limiting seats. A motor is mounted on at least one limiting seat, and a gear that meshes with the gear ring is mounted on the output shaft of the motor.

[0006] This solution uses a mounting plate to install measuring instruments. In use, a motor drives a gear to rotate, which in turn drives a gear ring to rotate, causing the measuring instruments mounted on the gear ring to rotate around the rolled steel, thus achieving comprehensive detection.

[0007] As an optimization, a circumferentially closed conductive ring is fixed in at least one of the limiting grooves. A conductive hole is provided on the instrument mounting plate, and a conductive plate electrically connected to the conductive ring is placed inside the conductive hole. A conductive plate in contact with the conductive ring is fixed on the limiting block. This optimized design allows the limiting block, conductive ring, and conductive plate to form a current path. Power can be supplied simply by inserting the plug of the detection instrument into the conductive hole, making it more convenient to use and meeting the power supply requirements during gear rotation.

[0008] As an optimization, the two limiting seats have U-shaped slots on their opposite sides. The width of the U-shaped slots is adapted to the width of the gear ring, and the limiting block is fixed to the inner wall of the U-shaped slot. This optimization solution avoids interference with the gear ring by setting U-shaped slots on the limiting seats, while simultaneously limiting the movement of the gear ring.

[0009] As an optimization, the support base is provided with a lifting cavity, and the two support rods are connected to a lifting mechanism set in the lifting cavity. This optimized solution, by setting up a lifting mechanism, facilitates the adjustment of the height of the gear ring to meet the detection requirements at different heights. By setting up a lifting cavity, not only is it convenient to install the lifting mechanism, but it also helps to reduce the overall weight of the support.

[0010] As an optimization, the lifting mechanism includes a bidirectional screw rotatably connected to the support seat, and a guide rod parallel to the bidirectional screw. Two screw blocks are threadedly connected to the bidirectional screw, with opposite thread directions, and each screw block is slidably connected to the guide rod. Support rods are hinged to the screw blocks, and the support rods on the two screw blocks are arranged crosswise. A lifting rod is hinged to the upper end of each support rod, and the lifting rod is fixedly connected to the support rod. The inner wall of the lifting cavity is provided with guide grooves extending vertically and adapted to the two ends of the lifting rod. This optimized lifting mechanism adopts a scissor-type structure, allowing for lifting and lowering by rotating the bidirectional screw, making it more convenient to use.

[0011] This solution also provides a method for using the rotating bracket of the above-mentioned steel rolling measuring instrument: the height of the gear ring is adjusted by the lifting mechanism, the measuring instrument is then installed on the instrument mounting plate and connected to the conductive hole. Next, the rolled steel is passed through the inner hole of the gear ring, the motor is controlled to work, and the motor drives the gear to rotate. When the gear rotates, it drives the gear ring to rotate, thereby causing each measuring instrument to rotate around the rolled steel, so as to achieve comprehensive detection of the rolled steel.

[0012] The beneficial effects of this invention are as follows: By using a motor and gear transmission, each measuring instrument rotates around the rolled steel, thereby achieving comprehensive detection, avoiding blind spots, and ensuring detection results; by cooperating with the bidirectional screw and two screw blocks, the height of the gear ring can be adjusted when rotating the bidirectional screw, thereby achieving height adjustment of the detection instruments, meeting the usage requirements of different detection heights, and expanding the scope of application.

[0014] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0015] like Figure 1 The rotating bracket for steel rolling measuring instruments shown includes a bearing base 1, two bearing rods 10 mounted on the bearing base 1, and a gear ring 13 located between the two bearing rods 10. The axis of the gear ring extends laterally, and a plurality of instrument mounting plates 17 distributed circumferentially are fixed on the inner wall of the gear ring 13. The two end faces of the gear ring are respectively provided with circumferentially penetrating limiting grooves 14.

[0016] In this embodiment, there are four instrument mounting plates 17, which are evenly distributed circumferentially for use with safety testing instruments. One end of each instrument mounting plate has a conductive hole 18 for inserting the power plug of the testing instrument, facilitating power supply to the testing instrument.

[0017] The support rods are set vertically, and the upper ends of the two support rods 10 are respectively fixed with limit seats 11. Limit blocks 12 extending into the limit grooves are fixed on the limit seats 11. The limit blocks are horizontal columnar. Each limit seat is provided with a limit block that extends to the limit grooves on both sides, forming a support limit for the gear ring.

[0018] To facilitate the installation of the gear ring and avoid interference, the two limiting seats in this embodiment are provided with U-shaped slots on their opposite sides. The width of the U-shaped slots is adapted to the width of the gear ring, and the limiting blocks are fixed to the inner sidewalls of the U-shaped slots.

[0019] At least one limiting seat is equipped with a motor 20, and the output shaft of the motor is equipped with a gear 21 that meshes with a gear ring 13. When the motor rotates, it drives the gear ring 13 to rotate, causing the measuring instrument to rotate around the rolled steel. In this embodiment, a bracket 19 is fixedly connected to one of the limiting seats, and the motor is mounted on the bracket 19. The pitch circle diameter of the gear is smaller than that of the gear ring, so that when the motor drives the gear to rotate, the gear ring rotates slowly, thereby improving the detection effect of the measuring instrument.

[0020] A conductive ring 15, which is circumferentially closed, is fixed in at least one limiting groove. A conductive plate, which is electrically connected to the conductive ring 15, is provided in the conductive hole 18. A conductive sheet 16, which contacts the conductive ring 15, is fixed on the limiting block. In this embodiment, a conductive ring is provided in the limiting groove on one side. During installation, the conductive sheet is connected to an external power supply cable. The conductive sheet, conductive ring, and conductive plate form a circuit to provide the required power to the measuring instrument. Furthermore, the circumferentially closed setting of the conductive ring ensures the continuity of conduction when the gear ring rotates, avoiding open circuits.

[0021] The support seat has a lifting cavity 2, providing lifting space for the lifting rod 9. The two support rods are connected to a lifting mechanism located in the lifting cavity. Specifically, the lifting mechanism includes a bidirectional screw 4 rotatably connected to the support seat 1, and a guide rod 5 parallel to the bidirectional screw. The guide rod is welded and fixed, and is located below the bidirectional screw, limiting and guiding the movement of the screw block 6. Two screw blocks 6 are threadedly connected to the bidirectional screw, with opposite thread directions, and are slidably connected to the guide rod. Support rods 8 are hinged to the screw blocks, and the support rods on the two screw blocks are arranged crosswise. The upper ends of the two support rods 8 are hinged to the lifting rod 9, which is fixed to the support rod 10. The lifting rod is horizontally arranged, and the lower end of the support rod is supported and fixed to the upper surface of the lifting rod. The inner wall of the lifting cavity has a guide groove 22 extending vertically and adapted to both ends of the lifting rod, providing guidance for the vertical movement of the lifting rod. In this embodiment, guide blocks are fixed at both ends of the lifting rod 9, and the guide blocks slide up and down along the guide groove. The top of the screw block is fixed with a lower support 24. The lower end of the support rod is hinged to the lower support, and the upper end of the support rod is hinged to an upper support. The bottom of the lifting rod is provided with a sliding groove that matches the upper support. The two support rods are rotatably connected at the intersection to form a scissor-type lifting mechanism to adjust the height of the gear ring 13.

[0022] To facilitate the rotation of the bidirectional screw, a bearing seat extends from one end of the bidirectional screw in this embodiment, and a knob 7 is fixedly installed at the end of the bidirectional screw extending from the bearing seat. The surface of the knob 7 is frosted and non-slip. Rotating the knob 7 can drive the bidirectional screw 4 to rotate, thereby moving the two screw blocks relative to each other or away from each other. Through the setting of the two support rods, the gear ring is raised and lowered, thereby adjusting the gear ring to a suitable height. Compared with the original pull-out method, this method is not only easier for the operator to operate, but also more flexible, and also avoids squeezing the operator's hands, and has higher adjustment performance.

[0023] Mounting plates 3 are symmetrically welded on both sides of the bottom end of the bearing seat 1. Four sets of mounting bolts are reserved on the mounting plates 3. During the adjustment process, the guide block 23 and the guide groove 22 are combined to ensure the stability of the lifting rod 9 when it moves. The mounting bolts on the mounting plates 3 make it easy to fix the device on the steel rolling production line.

[0024] The method of using the rotating bracket for measuring instruments in this embodiment is as follows: The height of the gear ring is adjusted via the lifting mechanism. Then, the measuring instruments are installed on the instrument mounting plate and connected to the conductive holes. Next, the rolled steel is passed through the inner hole of the gear ring. The motor is then controlled to operate, driving the gears to rotate. The rotation of the gears drives the gear ring to rotate, causing each measuring instrument to rotate around the rolled steel, thus achieving comprehensive inspection of the rolled steel. Specifically, the device is first fixed to the rolling steel production line using the mounting bolts pre-installed on the mounting plate 3. Then, the knob 7 is rotated to drive the bidirectional screw 4 to rotate, causing the screw block 6 to move under the action of the thread and guide rod 5. During this movement, the support rod 8 rotates, pushing the lifting rod 9 to move, thereby adjusting the gear ring 13 to a suitable height. During adjustment, the guide block 23 and guide groove 22 combine to ensure the stability of the lifting rod 9 during movement. The scissor-type lifting mechanism not only facilitates operation for workers but also provides high flexibility, while avoiding hand injuries. After adjustment, the measuring instrument is fixed on the instrument mounting plate 17 inside the gear ring 13 and connected to the conductive hole 18. Then, the rolled steel is passed through the gear ring 13, and the external electrical control mechanism is activated to control the motor 20. The motor 20 drives the gear ring 13 to rotate via the gear 21. Because the gear ring 13 is larger than the gear 21, it rotates slowly, causing the measuring instrument fixed on the instrument mounting plate 17 to rotate around the rolled steel. This allows for comprehensive inspection of the rolled steel, avoiding blind spots and ensuring effective detection. During rotation, the limiting block 12 and the limiting groove 14 combine to limit the gear ring 13, while the conductive sheet 16 and the conductive ring 15 combine to provide the necessary power to the measuring instrument. Finally, the measuring instrument transmits the detection results to the backend and displays them on the screen.
