Description

Technical Field

[0001] This utility model relates to the technical field of limiting support devices, specifically a spatial radius limiting support device. Background Technology

[0002] Limiting support devices are crucial components specifically designed for mechanical systems. Their primary function is to ensure that moving parts can be accurately stopped at specific positions. Through precise positioning and support, these devices effectively prevent mechanical parts from exceeding their predetermined range of motion, thus protecting the entire equipment from damage. The use of limiting support devices not only improves the operational safety of mechanical equipment but also ensures the accuracy and reliability of mechanical movements, which is of paramount importance for maintaining the long-term stable operation of equipment. Spatial radius limiting support devices are one type of limiting support device, specifically designed for limiting and supporting arc-shaped structures. However, existing spatial radius limiting support devices still have some drawbacks. For example, they can generally only fix and support arc-shaped structures of the same size, and cannot be quickly adjusted to meet different usage requirements. Furthermore, they cannot achieve the effect of rolling support during limiting and supporting. Therefore, we propose a spatial radius limiting support device. Utility Model Content

[0003] The purpose of this invention is to provide a spatial radius limiting support device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A spatial radius limiting support device includes a base and a horizontal plate;

[0006] The base has pads around its bottom, handles on both the front and rear ends of its top, a servo motor at the center of its top, a motor shaft on top of the servo motor, a connecting plate on top of the motor shaft, and a horizontal plate on top of the connecting plate.

[0007] An electric telescopic rod is installed at the top center of the horizontal plate. A fixing block is installed at the top center of the electric telescopic rod. A ball bearing is installed on the top of the fixing block. Telescopic rods are installed at the center of both the left and right sides of the horizontal plate. A connecting block is installed at the end of the telescopic rod away from the horizontal plate. An internal threaded hole is vertically installed at the top center of the connecting block. The connecting block is threaded to a matching external threaded rod through the internal threaded hole. A fixing block is installed at the top of the external threaded rod. An auxiliary ball bearing is installed at the top of the fixing block.

[0008] Furthermore: Fixing plates are provided on both the left and right sides of the top front face of the horizontal plate, and lighting lamps are provided on the top of the fixing plates. Battery packs are provided on both the left and right sides of the top rear face of the horizontal plate, and the battery packs are electrically connected to the lighting lamps at the corresponding positions.

[0009] Furthermore: bolts are installed around the bottom of the connecting plate and the bottom of the horizontal plate, and a rubber gasket layer is installed between the top of the connecting plate and the bottom of the horizontal plate.

[0010] Furthermore: the bottom of the electric telescopic pole is provided with a mounting base, and the top center of the horizontal plate is provided with a mounting groove that matches the mounting base.

[0011] Furthermore: the horizontal plate and the base are set horizontally parallel to each other, and the length and width of the horizontal plate are both smaller than the length and width of the base.

[0012] Furthermore: the bottom of each external threaded rod is equipped with a rotating paddle, and the rotating paddle is fixedly welded to the external threaded rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This spatial radius limiting support device, when supporting an arc-shaped structure, is first erected above an electric telescopic rod. This ensures the top of the ball bearings contacts the center of the inner wall of the arc-shaped structure. Then, depending on the size of the arc-shaped structure, the positions of the external threaded rods on both sides are adjusted by stretching the telescopic rod. After adjustment, the external threaded rods are rotated, engaging with the internal threaded holes to adjust the position of the auxiliary ball bearings up and down. This allows for support from both sides of the inner wall of the arc-shaped structure, and this setup can also support arc-shaped structures of different sizes. During support, a servo motor drives a horizontal plate to rotate, providing rolling support to the inner wall of the arc-shaped structure. Attached Figure Description

A ball bearing 12 is installed on the top of the fixing block 11. Telescopic rods 13 are installed at the center of both the left and right sides of the horizontal plate 7. A connecting block 14 is installed at the end of the telescopic rod 13 away from the horizontal plate 7. An internal threaded hole 15 is vertically threaded through the top center of each connecting block 14. The connecting block 14 is threadedly connected to a matching external threaded rod 16 through the internal threaded hole 15. A fixing block 18 is installed on the top of each external threaded rod 16. An auxiliary roller is installed on the top of each fixing block 18. When the arc-shaped structure needs support, the ball 12 is placed above the electric telescopic rod 9, and the top of the ball 12 contacts the inner wall of the arc-shaped structure. Then, according to the size of the arc-shaped structure, the position of the external thread rods 16 on the left and right sides is adjusted by stretching the telescopic rod. After the adjustment is in place, the external thread rod 16 is rotated so that it cooperates with the internal thread hole 15 to adjust the position of the auxiliary ball 19 up and down. In this way, the arc-shaped structure can be supported from both sides of the inner wall. At the same time, the cross plate 7 can be rotated by the drive of the servo motor 4, so that the inner wall of the arc-shaped structure can be rolled for support.
