Embodiment Construction
[0017] see figure 1 -- Figure 9 , The utility model comprises a wheel 1 and an axle 2, and the wheel 1 is installed at two ends of the axle 2. The key technology is to install the machine base 4 on the axle 2 through the axle seat 3, the machine base 4 is a square structure, the four corners of the top surface are provided with threaded holes, and the screws are fixed on the four corners of the top surface of the machine base 4 through the threaded holes. 4 columns 6, a group of cylindrical springs 5 are set on each column 6, and a supporting plate 7 is penetrated at the upper end of the column 6. The supporting plate 7 is a square flat plate, and each of its four corners has a fourth diameter greater than the diameter of the middle part of the column 6. The round hole, the spring 5 is located between the base 4 and the supporting plate 7, a large circular hole vertically through is respectively opened in the middle of the base 4 and the supporting plate 7, and a gasket 8 ...

The invention belongs to the field of machinery and particularly relates to a hydraulic cylinder wheel barrow. The hydraulic cylinder wheel barrow comprises wheels and a barrow shaft. The wheels are arranged at both ends of the barrow shaft. The invention adopts the following key technology that an engine base is arranged on the barrow shaft; uprights are arranged on the engine base; springs are sleeved on the uprights; supporting plates are arranged at the upper ends of the uprights in a penetrating manner; the springs are positioned between the engine base and the supporting plates; and the middles of the engine base and the supporting plates are respectively provided with vertical through big round holes. The hydraulic cylinder wheel barrow has the beneficial effects that the bottom of a hydraulic cylinder is supported by the compressed springs in a floating mode; the top of the hydraulic cylinder is limited by adopting washers and nuts, which are fixed at the upper ends of the uprights; the pressure sum of the assembled springs is slightly greater than the weights of the hydraulic cylinder and the supporting plates, so that when the hydraulic cylinder does not work, a gap of 10 to 20 mm is kept between the bottom of the hydraulic cylinder and a wheel barrow supporting surface 10 and the hydraulic cylinder is in a suspended state; the hydraulic cylinder wheel barrow is very convenient to move and can be manually pushed to move between different stations; and a flexible, convenient and rapid tool is provided for the movement of the large-scale hydraulic cylinder between different stations.
Description
technical field [0001] The invention belongs to the field of machinery, and in particular relates to a hydraulic cylinder trolley. Background technique [0002] In the machinery manufacturing industry, large-diameter hydraulic cylinders placed vertically are often used to generate huge pressure to correct welding deformation of large structures or prefabricate the deformation required by the design. Large-diameter hydraulic cylinders are very heavy, and it is difficult to move between different stations by manpower; if cranes or forklifts are used to carry them, additional equipment and personnel are needed, and a larger work site is required, which is not economical. Contents of the invention [0003] The problem to be solved by the present invention is to provide a small trolley that can conveniently move the hydraulic cylinder in view of the above deficiencies. Its technical scheme is as follows: [0004] It includes wheels and axles, and the wheels are installed at b...
