Description

Technical Field

[0001] The utility model relates to a hoisting tool for an accumulator. Background Art

[0002] The accumulator is an energy storage device in the hydraulic and pneumatic system. It converts the energy in the system into compression energy or potential energy and stores it at the right time. When the system needs it, it converts the compression energy or potential energy into hydraulic or air pressure energy and releases it to replenish the system. When the system pressure increases instantly, it can absorb this part of the energy to ensure the normal pressure of the entire system.

[0003] There are two accumulators on the oil pump outlet module of our hydraulic oil station. The brand is Hydac, with a volume of 20L and a weight of 25KG. The accumulator is located in a small place. Every time it is inspected, it needs to be lifted up manually after the anchor screws are removed. When it is reinstalled, it needs to be put down manually. Because there is a groove at the bottom of the Hydac accumulator, an O-ring is installed inside, which contacts and squeezes the smooth surface of the base for sealing. If the reinstallation position is not correct, the O-ring will be squeezed out of the groove, or even squeezed and broken, causing leakage at the bottom of the accumulator. Every time the Hydac accumulator is hoisted, a lot of energy, manpower and material resources are consumed. Summary of the invention

[0004] The utility model aims to provide a lifting tool for an accumulator, which solves the problem that due to the narrow space at the equipment installation location, the steel cylindrical structure of the accumulator itself, the smooth barrel shape is not easy to apply manpower, and the bottom groove requires an O-ring seal. If the reinstallation position cannot be in place at one time, the sealing ring is easily damaged, resulting in leakage.

[0005] The above purpose is achieved through the following technical solutions:

[0006] A lifting tool for an accumulator, comprising: an accumulator, wherein the top of the accumulator is provided with a locking nut, the locking nut is integrally connected to the accumulator, the accumulator is lifted vertically upward by the lifting tool, the lifting tool is composed of a threaded sleeve, a body and a lifting ring, the lifting ring is connected to the top of the body, the bottom of the body is connected to the threaded sleeve, the threaded sleeve is screwed into the locking nut at the top of the accumulator through a threaded structure, and the locking nut, the body and the lifting ring are integrally connected.

[0007] The lifting tool for the accumulator is characterized in that a spring buckle is buckled on the lifting ring, and a pull rope is connected to the spring buckle.

[0008] The main body of the lifting tool for the accumulator is a trapezoidal steel plate structure which is narrow at the top and wide at the bottom.

[0009] Beneficial effects of the utility model:

[0010] 1. The utility model can easily install the Hydac accumulator in a precise position without consuming a lot of physical strength. It greatly improves the work efficiency and installation quality of maintenance personnel, and mainly provides labor-saving and time-saving assistance for the disassembly and installation of Hydac accumulators during maintenance.

[0011] 2. The utility model can accurately ensure that the installation position of the bottom of the accumulator is correct, ensure that the bottom O-ring will not be damaged, facilitate the disassembly and assembly of equipment in narrow spaces, and improve the reliability of equipment maintenance. It has the characteristics of simple disassembly and assembly tool structure, low cost, and easy promotion.

[0012] 3. According to the structural characteristics of the Hydac accumulator, the utility model designs a screw sleeve that can be sleeved on the locking nut on the top of the accumulator. The thread sizes match and can be reliably fixed. A lifting ring is added to the upper part of the screw sleeve to make it more convenient to disassemble and assemble the accumulator in a narrow space.

[0013] 4. The screw sleeve of the lifting tool of the utility model is connected to the locking nut on the top of the accumulator to fix the accumulator. When working, the lifting ring of the lifting tool is connected to the lifting tool, which can realize the safe and accurate lifting and installation of the accumulator, and ensure that the bottom sealing ring is installed in place at one time. The size of the nut of the disassembly tool can be replaced by simply changing the size of the screw sleeve, which can also be realized when disassembling accumulators of different sizes, thereby improving the efficiency of inspection and maintenance and reducing maintenance costs.

[0020] A lifting tool for an accumulator, wherein a spring buckle 6 is buckled on the lifting ring, and a pull rope 7 is connected to the spring buckle. The main body is a trapezoidal steel plate structure that is narrow at the top and wide at the bottom. A screw sleeve is processed to fix it to the accumulator body, and then a lifting ring and a lifting tool are used to dismantle and install the equipment, which is equivalent to placing the force point on the top. When in use, the threaded structure in the screw sleeve is screwed into the locking nut of the accumulator, so that the accumulator and the lifting tool are integrated, and then the accumulator is lifted vertically upward by the pull rope, which effectively ensures that the entire accumulator is in a balanced position and that the accumulator is not skewed, making it easy to dismantle and install. It can effectively enter a narrow space for disassembly and assembly of the equipment, ensuring that the bottom O-ring is reinstalled in place at one time, greatly improving the work efficiency of maintenance and reducing the manpower and financial resources for equipment maintenance.
