Description

Technical Field

[0001] The utility model relates to the technical field of equipment maintenance platforms, in particular to a special maintenance platform for floating head heat exchanger heads. Background Art

[0002] Floating-head heat exchangers are common heat exchange equipment in chemical production plants, typically used in processes with high temperature differentials and high pressures. Their foundations are typically elevated above the ground, making disassembly and maintenance difficult. Furthermore, the large size and weight of the heat exchanger heads make elevated operations unsafe. Furthermore, after removal, the heat exchanger heads are typically hoisted to the ground using a truck crane, which is costly, space-constrained, and inconvenient, resulting in low efficiency and time-consuming operations. Therefore, a dedicated maintenance platform for floating-head heat exchanger heads is needed to improve the current situation. Utility Model Content

[0003] The purpose of the utility model is to provide a special maintenance platform for floating head heat exchanger heads to solve the problems of inconvenience in lifting due to space constraints, low efficiency, long operation time and high cost during the disassembly and maintenance of floating head heat exchangers.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions: a special maintenance platform for floating head heat exchanger heads, which is used to repair floating head heat exchangers to be repaired, including: a working platform; a lifting frame, which is fixed to one side of the working platform, and a lifting device is installed on the top of the lifting frame, and the lifting device is used to lift the heat exchanger head; a suspension groove is provided on the working platform below the lifting device, and the suspension groove is used to temporarily store the heat exchanger head.

[0005] A positioning pin hole is provided in the suspension groove. When the heat exchanger head is placed in the suspension groove, the heat exchanger head can be fixed to the suspension groove through the positioning pin.

[0006] Furthermore, an openable and closable suspension groove cover is provided on the suspension groove, and the suspension groove cover is flush with the horizontal plane of the working platform.

[0007] Furthermore, the hoisting frame is a gate-shaped bracket, the bottom end of the gate-shaped bracket is supported and fixed on the bottom of the suspension groove, and the top end of the gate-shaped bracket is installed with the hoist. Furthermore, the ladder provided on the working platform is connected to the ground and is provided with a protective cage.

[0008] Furthermore, a platform guardrail is provided at the edge of the working platform.

[0009] Furthermore, the working platform is supported from below by platform columns, and reinforcing beams are connected between the platform columns.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] First, the floating head heat exchanger head dedicated maintenance platform is simple to manufacture, and its use cost is simpler, more convenient and more efficient than conventional automobile crane-assisted disassembly and assembly.

[0012] Second, a suspension groove is set up with positioning pins inside. When the heat exchanger head is lowered into the suspension groove with a hoist, it is fixed with the positioning pins. The placement of the heat exchanger head is as safe as placing it on the ground. The suspension groove cover is placed on the top of the suspension groove to prevent workers from stepping on empty space during construction.

[0013] Third, the bottom of the lifting frame is fixed to the bottom of the platform suspension slot, which lowers the center of gravity of the lifting force and is not easy to tip over; reinforcing beams are set between the platform columns to make the whole more stable.

[0014] Fourth, the ladder is equipped with a guard cage and platform guardrails are set on the edge of the working platform to fully ensure the construction safety of the workers. BRIEF DESCRIPTION OF THE DRAWINGS
