Description

Technical Field

[0001] The utility model relates to the technical field of chemical industry, in particular to a cart for transporting piston rods. Background Art

[0002] The piston rod is a connecting component that supports the piston to do work. It is used in the hydraulic cylinder and the cylinder motion actuator. It is a moving component that moves frequently and has high technical requirements. The quality of its processing directly affects the life and reliability of the entire product. The piston rod is also a vulnerable part during use, so the market demand is large and mass production is required. The piston rod has a relatively simple structure, but the aspect ratio is very large. It belongs to the slender shaft type parts. It is easy to be subjected to bending stress during transportation, resulting in product failure and economic losses.

[0003] In order to solve the above technical problems, the existing patent CN206394669U discloses a special trolley for transporting piston rods, including a body, rollers are installed at the four corners of the bottom of the body, a cylinder is fixed on the bottom surface of the body, a horizontal push plate is installed on the top of the piston rod of the cylinder, a horizontal partition is provided in the middle part of the body, a number of through holes are evenly arranged on the partition, a rectangular frame is provided at the upper port of the body, and a number of limit assemblies are provided in the rectangular frame; the limit assemblies include two parallel and horizontal sliding rods, a number of blocking blocks are symmetrically provided on the inner sides of the two sliding rods, and the side of the sliding block facing away from the sliding rod where the blocking block is located is a concave arc surface, and horizontal sliding sleeves are fixed at both ends of each sliding rod, and the sliding rod is slidably connected to the rectangular frame through the sliding sleeves at both ends of the sliding rod. The utility model has a simple and compact structure, has high stability in the process of transporting the piston rod, and the piston rod will not collide. The piston rod is pushed out by the cylinder to push the push plate, which is convenient for taking out the piston rod. This structure facilitates the removal of the piston rod to a certain extent, but is not convenient during the loading and unloading process of the cart, and the interior is not stable enough. If the internal piston rod is placed in an irregular position, it is easy to overturn during the pushing process. Therefore, how to design a cart for transporting piston rods that is convenient for loading and unloading, easy to push, and has good stability is a technical problem that technical personnel in this field currently need to solve.
