Description

Technical Field

[0001] The utility model relates to the technical field of diesel engine manufacturing, in particular to a pre-installed lifting platform for a ship diesel engine cylinder. Background Art

[0002] The pre-installation work of the diesel engine cylinder block involves the installation of parts on the flat surface of the cylinder block, which is a high-altitude work. Therefore, a work platform needs to be arranged around the cylinder block for workers to go up and down, and to protect the safety of workers working on the flat surface of the cylinder block. The current cylinder block work platform is a welded steel structure platform, which is relatively heavy and can only be adjusted by driving. The opening of the platform layout increases the work preparation time. At the same time, the layout process occupies driving resources and affects the work plan of other workstations. Due to the different external dimensions of the cylinder blocks of different models, the cylinder block work platform needs to be designed separately, which increases the manufacturing cost of the diesel engine.

[0003] Therefore, it is necessary to provide a new marine diesel engine cylinder pre-installation lifting platform to solve the above-mentioned technical problems. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a pre-installed lifting platform for a ship diesel engine cylinder.

[0005] The ship diesel engine cylinder pre-installed lifting platform provided by the utility model comprises: a main working platform, an auxiliary working platform, a first guardrail, a second guardrail, a first hydraulic rod and a first support leg, wherein an auxiliary working platform is arranged on one side of the main working platform, the upper surface of the main working platform is fixedly connected with the first guardrail, the upper surface of the auxiliary working platform is fixedly connected with the second guardrail, the lower surface of the main working platform is symmetrically fixedly connected with four first hydraulic rods, and the surfaces of the four first hydraulic rods are symmetrically fixedly connected with the first support leg.

[0006] By extending and retracting the first hydraulic rod, the height of the main working platform is adjusted to meet the height requirements of different cylinders. The first guardrail and the second guardrail protect the main working platform and the auxiliary working platform, control the auxiliary working platform to approach or move away from the main working platform, and adjust the range of activities of the staff. The first support leg can increase the supporting performance of the first hydraulic rod.

[0007] Preferably, a ladder body is fixedly connected to one side of the main working platform.

[0008] The main body of the ladder acts as a bridge between the ground and the main working platform, providing workers with a safe and convenient up and down passage, ensuring that they can move smoothly between different heights and complete various tasks efficiently.

[0009] Preferably, four bottom pillars are symmetrically arranged below the main working platform, a movable rod is slidably connected to the surface of the bottom pillar, and the top of the movable rod is fixedly connected to the lower surface of the main working platform, limiting pins are slidably penetrated through the circular holes on the surface of the bottom pillar and the movable rod, and four second legs are symmetrically and fixedly connected to the surface of the bottom pillar.

[0010] After the height of the main working platform is determined, the limit pin enters the round holes of the bottom support and the movable rod to mechanically limit the main working platform to prevent the main working platform from suddenly dropping due to failure of the second guardrail. The second support leg can increase the supporting performance of the bottom support.

[0011] Preferably, a second hydraulic rod is symmetrically fixedly connected to one side of the main working platform close to the auxiliary working platform, and a movable end of the second hydraulic rod is fixedly connected to the surface of the auxiliary working platform.

[0012] By extending and retracting the second hydraulic rod, the auxiliary working platform can be controlled to move closer to or farther away from the main working platform, thereby adjusting the range of activities of the staff.

[0013] Preferably, a guide seat is symmetrically fixedly connected to the lower surface of the main working platform, and a guide rod is symmetrically fixedly connected to the lower surface of the auxiliary working platform, and the guide rod is slidably connected with the rectangular hole of the guide seat.

[0014] When the auxiliary working platform approaches or moves away from the main working platform, the guide rod slides along the inside of the rectangular hole of the guide seat to ensure that the auxiliary working platform does not shake during movement, thereby improving the stability of the movement of the auxiliary working platform.

[0015] Preferably, the edge of the ladder body is provided with rounded corners.

[0016] The friction force at the edge of the ladder body can be reduced, making it convenient for workers to climb onto the main working platform by holding the ladder body, thereby increasing the practicality of the ladder body.

[0017] Compared with the related art, the marine diesel engine cylinder pre-installation lifting platform provided by the utility model has the following beneficial effects:

[0018] The utility model provides a pre-installed lifting platform for a ship diesel engine cylinder:
