Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline transportation detection and relates to an omnidirectional wheel device for steel pipe traveling detection. Background Art

[0002] The transportation of steel pipes is generally divided into linear transportation and spiral transportation. In the prior art, no matter which type of transportation is used, the measurement of the travel speed is achieved through an encoder, that is, the encoder is connected to the detection wheel through a coupling. However, for the spiral transportation of steel pipes, its speed is divided into a linear travel speed component and a rotational travel speed component. In order to more accurately detect the speed of the spiral transportation of steel pipes in real time, it is necessary to detect these two components. However, the existing detection wheel cannot offset the corresponding travel speed component. If it cannot offset, it cannot accurately detect the travel speed component to be detected.

[0003] In view of this, the utility model proposes an omnidirectional wheel device for steel pipe walking detection to better meet the needs of production control. Utility Model Content

[0007] Moreover, the omnidirectional wheel body includes a double-row wheel hub, an offset wheel and a limiting tooth plate.

[0020] An omnidirectional wheel device for steel pipe walking detection, its innovation lies in: comprising an omnidirectional wheel body 4 and a rotating mounting frame, the rotating mounting frame comprising a rotating seat, a vertical plate 9, a mounting platform, an extended mounting plate 11 and an encoder mounting frame 2, vertical plates are symmetrically installed on the left and right ends of the rotating seat, mounting platforms are horizontally arranged on the top surfaces of the two vertical plates, bearing seats 6 are installed on the two mounting platforms, the omnidirectional wheel body is rotatably installed between the two bearing seats through a rotating shaft 5, an extended mounting plate is horizontally extended on one side of the rotating seat, an L-shaped encoder mounting frame is installed on the extended mounting plate, and an encoder 1 connected to the rotating shaft of the omnidirectional wheel body through a coupling 3 is installed on the encoder mounting frame.

[0021] The utility model uses the offset wheel on the omnidirectional wheel to offset the rotating speed component of the steel pipe or the linear speed component, thereby completing the measurement of the corresponding speed. That is, when the steel pipe is parallel to the omnidirectional wheel axis, the spiral speed component is measured; when the steel pipe is perpendicular to the omnidirectional wheel axis, the linear speed component is measured.

[0022] The omnidirectional wheel body includes a double-row hub 15, an offset wheel 12 and a limit tooth plate 14. The double-row hub is composed of an integrally made connecting sleeve and a hub tooth plate. Hub tooth plates are arranged on the outer edges of both ends of the connecting sleeve. The mounting teeth 16 on the two hub tooth plates are staggered. Both ends of each mounting tooth are provided with a wheel axle mounting groove 17 with an outer side and an end face opening. An offset wheel is rotatably mounted between two wheel axle mounting grooves on each wheel hub tooth plate. The wheel axle of the offset wheel is placed in the wheel axle mounting groove. The axis of the offset wheel is perpendicular to the axis of the double-row hub. A limit tooth plate is installed on the outer end face of each wheel hub tooth plate by rivets 13. The teeth on the limit tooth plate are located on the outer side of the wheel axle mounting groove. A conical rubber head 18 extending into the wheel axle mounting groove is provided on the inner side of the limit tooth plate. The axle mounting groove with openings on the outer side and end face can facilitate the installation of the offset wheel. After the offset wheel is installed, in order to prevent it from moving in the radial direction, a conical rubber head is inserted on the outer side of the axle mounting groove. The conical rubber head is used to squeeze and limit the axle of the offset wheel to improve the measurement accuracy.

[0023] The rotating seat includes a fixed base plate 10, a rotating plate 8, a rotating center axis 7 and a pin. A rotating center axis is provided in the middle of the upper end surface of the fixed base plate, and a rotating plate is mounted on the rotating center axis.

The utility model facilitates the rotation of the omnidirectional wheel body through the setting of the rotating mounting frame, thereby meeting the measurement requirements of different walking speed components.
