Description

Technical Field

[0001] This utility model relates to the field of pipeline transportation technology, specifically to a pipeline transportation vehicle. Background Technology

[0002] A pipeline transfer vehicle is a special engineering vehicle designed for operations inside pipelines. It acts as a "vehicle" and "mobile workstation" for pipeline maintenance personnel, enabling safe and efficient movement of pipelines on the surface of the transfer vehicle for short-distance displacement operations.

[0003] However, current pipeline transfer vehicles have a simple structure. When transferring concrete pipelines, the heavy weight of the pipelines causes the rollers to bear a large force. Currently, the transfer rollers and roller supports are generally fixed to the base directly by bolts or welding. Once wear or damage occurs, subsequent replacement is quite troublesome, affecting the efficiency of transfer. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a pipeline transfer vehicle that can directly position the roller bracket and transfer rollers through the outer frame, which facilitates installation and disassembly, thereby solving the problems mentioned in the background art.

[0005] This utility model is achieved through the following technical solution: a pipeline transfer vehicle, including a base, a base plate installed at one end of the base, installation grooves provided at the four corners of the base, one end of the installation groove expanding outward to form a limiting groove, a limiting plate inserted into the limiting groove, a roller bracket installed on the surface of the limiting plate, a detachable transfer roller movably installed on the roller bracket, and an outer frame fitted around the base to limit the limiting plate, the roller bracket and the roller.

[0006] As a preferred technical solution, both sides of the roller bracket are provided with L-shaped grooves, and L-shaped plates are provided in the L-shaped grooves. The L-shaped plates are provided with mounting holes at the center of the transfer roller, and bearings are installed in the mounting holes. A shaft is installed at the center of the roller bracket, and both ends of the shaft are inserted into the inner ring of the bearing. The outer surfaces of the L-shaped plates, roller brackets and limiting plates are flush and abut against the inner surface of the outer frame.

[0007] As a preferred technical solution, both sides of the transfer roller are provided with multiple ball grooves in an annular structure. Balls are movably installed in each ball groove, and a portion of each ball extends to the outside through the opening of the ball groove and contacts the inner side of the roller bracket.

[0008] As a preferred technical solution, both ends of the L-shaped groove are provided with connecting grooves, and both ends of the L-shaped plate are equipped with connecting blocks. The connecting blocks are inserted into the connecting grooves, and the cross-sections of the connecting blocks and the connecting grooves are both set in a "T" shape.

[0009] As a preferred technical solution, slots are provided on both sides of the outer frame and the base, and multiple support positioning plates are provided between the outer frame and the base. Both ends of the support positioning plates are inserted into the corresponding slots, and the support positioning plates are all fixed to the base plate by bolts.

[0010] As a preferred technical solution, a material reduction port is provided at the center of the base, penetrating the base and the bottom plate.

[0011] As a preferred technical solution, the outer frame is made of steel.

[0012] As a preferred technical solution, the thickness of the L-shaped plate is matched with the thickness of the two side plates of the roller bracket.

[0013] The beneficial effects of this utility model are: the utility model has a simple structure, with the transfer roller, roller bracket and base set separately. After the outer frame moves downward, the transfer roller and roller bracket can be directly taken out and separated, and the transfer roller and roller bracket can be replaced independently and quickly, avoiding the impact on transfer efficiency due to replacement.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0021] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0022] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a pipeline transfer vehicle of this utility model includes a base 1, a base plate 2 is installed at one end of the base 1, and mounting grooves 14 are provided at the four corners of the base 1. One end of the mounting groove 14 expands outward to form a limiting groove 15. A limiting plate 12 is inserted into the limiting groove 15. A roller bracket 4 is installed on the surface of the limiting plate 12. A detachable transfer roller 8 is movably installed on the roller bracket 4. An outer frame 3 is fitted on the outside of the base 1 to limit the limiting plate 12, the roller bracket 4 and the roller.

[0024] In this embodiment, L-shaped grooves are provided on both sides of the roller bracket 4, and L-shaped plates 5 are provided in the L-shaped grooves. The L-shaped plates 5 are provided with mounting holes at the center of the transfer roller 8, and bearings are installed in the mounting holes. A shaft 6 is installed at the center of the roller bracket 4, and both ends of the shaft 6 are inserted into the inner ring of the bearing. The outer surfaces of the L-shaped plates 5, the roller bracket 4 and the limiting plate 12 are flush with each other and abut against the inner surface of the outer frame 3.

[0025] In this embodiment, both sides of the transfer roller 8 are provided with a ring structure with multiple ball grooves. Balls 7 are movably installed in each ball groove. A portion of each ball 7 extends to the outside through the opening of the ball groove and contacts the inner side of the roller bracket 4.

[0026] In this embodiment, both ends of the L-shaped groove are provided with connecting grooves, and both ends of the L-shaped plate 5 are equipped with connecting blocks 9. The connecting blocks 9 are inserted into the connecting grooves, and the cross-sections of the connecting blocks 9 and the connecting grooves are both set in a "T" shaped structure.

[0027] The L-shaped plate and the L-shaped groove can be connected together by the connecting groove and the connecting block to ensure the stability after installation and prevent it from falling out from the side of the L-shaped groove.

[0028] In this embodiment, slots 13 are provided on both sides of the outer frame 3 and the base 1, and multiple support positioning plates 10 are provided between the outer frame 3 and the base 1. Both ends of the support positioning plates 10 are inserted into the corresponding slots, and the support positioning plates 10 are all fixed to the base plate 2 by bolts.

[0029] The outer frame is positioned outside the limiting plate, roller bracket and L-shaped plate by the support positioning plate, which prevents the outer frame from falling on its own.

[0030] In this embodiment, a material reduction port 11 is provided at the center of the base 1, which penetrates the base 1 and the base plate 2, thereby reducing the material usage and cost of the base and the base plate.

[0031] In this embodiment, the outer frame 3 is made of steel, which increases its sturdiness and allows the outer surfaces of the limiting plate, roller bracket and L-shaped plate to abut against each other.

[0032] In this embodiment, the thickness of the L-shaped plate 5 is matched with the thickness of the two side plates of the roller bracket 4, so that the roller can contact the inner side of the L-shaped plate and the roller bracket. The ball bearings can position the rotating roller axially, avoiding back-and-forth swinging, so that the rotating roller can only rotate around the shaft.

[0033] Working principle:

[0034] During disassembly, the bolts on the support positioning plate can be unscrewed. After the bolts are removed, the support positioning plate can be pulled out of the slot. After the support positioning plate is removed, the outer frame can move downward along the outer side of the base until it moves away from the outside of the L-shaped plate, roller bracket and limit plate. After the outer frame is removed, the L-shaped plate can be taken out directly along the L-shaped groove. After the roller bracket is removed, the L-shaped plate can be separated directly and the shaft can be pulled out of the bearing, so that the rotating roller connected to the shaft can be replaced independently.

[0035] After the L-shaped plate and transfer rollers are disassembled, the roller bracket is also an independent unit. If the roller bracket is damaged or worn, it can be replaced independently, which greatly increases adaptability and convenience.

[0036] During installation, the limiting plate is inserted into the limiting groove from the outside in, so that the roller bracket is set in the mounting groove. The shaft on the transfer roller is inserted into the inner ring of the bearing, and the L-shaped plate is inserted into the L-shaped groove. After the outer frame is lifted, the outer surfaces of the limiting plate, roller bracket and L-shaped plate can abut against each other, thereby limiting and positioning the transfer roller and roller bracket.

[0037] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
