Problems solved by technology

[0002] Seamless steel pipes are raw material pipes. After thermal expansion processing, multiple processes such as straightening, leveling (beveling), non-destructive testing, spraying, and loading are required. In these processes, necessary handling work is required for steel pipes. Due to the large volume of the steel pipe after thermal expansion, it is very inconvenient to carry
In the prior art, hoisting equipment and manual cooperation are usually used to complete the process. Since the steel pipes are hoisted in the air, there are certain safety hazards, and the hoisting equipment is large, taking up a lot of space, and the flexibility and versatility are not good.

Embodiment Construction

[0022] Such as Figure 1-3 As shown, the transport trolley for heat-expanded steel pipes of the present invention comprises an underframe 1, four casters are arranged at the four corners of the bottom surface of the underframe 1, and a scissor lift 2 is fixed on the underframe 1, and the scissor lift 2 The lifting platform 3 is provided with four idlers 4 parallel to the lifting platform 3 and parallel to each other. The diameter of the two ends of the idler 4 is large, and the diameter of the middle is small. It is a V-shaped idler 41, and the four V-shaped idlers 41 pass through The bracket 5 is fixed on the lifting platform 3 , and one end of the V-shaped roller 41 is connected with a driving motor 6 .

[0023] Two of the four casters in this embodiment are universal brake casters 7, and the other two are directional casters 8. Both the universal brake casters 7 and the directional casters 8 are commercially available products. The two universal brake casters 7 is installe...

Abstract

The invention provides a conveying trolley for thermally-expanded steel pipes. The conveying trolley for the thermally-expanded steel pipes comprises a bottom frame. Casters are arranged on the lower surface of the bottom frame, a lift is fixed onto the bottom frame, and a plurality of carrier rollers which are placed parallelly are arranged on a lift table of the lift. The conveying trolley has the advantages that the thermally-expanded steel pipes do not need to be manually carried in conveying procedures and can be translated, loaded and unloaded in a workshop, and the conveying trolley is safe and flexible, and is low in cost and good in universality.

Description

technical field [0001] The invention relates to a transport trolley, in particular to a transport trolley for transporting heat-expanded steel pipes. Background technique [0002] Seamless steel pipes are raw material pipes. After thermal expansion processing, multiple processes such as straightening, leveling (beveling), non-destructive testing, spraying, and loading are required. In these processes, necessary handling work is required for steel pipes. Due to the large volume of the steel pipe after thermal expansion, it is very inconvenient to carry. In the prior art, hoisting equipment and manual cooperation are usually used to complete the process. Since the steel pipes are hoisted in the air, there are certain safety hazards, and the hoisting equipment is large, takes up a lot of space, and has poor flexibility and versatility. Contents of the invention [0003] The problem to be solved by the present invention is to provide a transportation trolley for heat-expanded...
