Description

Technical Field

[0001] This utility model relates to the technology of parallel installation of cooling tower groups, and in particular to a maintenance platform for parallel installation of cooling tower groups. Background Technology

[0002] Currently, cooling towers are widely used in power, chemical, metallurgical, pharmaceutical, data center and commercial building air conditioning fields. Their core function is to transfer the waste heat in the process circulating water or refrigerant condenser to the atmosphere through direct or indirect contact between water and air, thereby achieving the cooling of the circulating cooling water and ensuring the stable and efficient operation of the production process or air conditioning system.

[0003] Patent document with application number "CN202211150849.8" discloses a hydraulic balance regulating device and a parallel cooling tower group, belonging to the field of centralized central air conditioning hydraulic balance regulating technology. It includes a shell with an inlet channel for cooling circulating water, at least two outlet channels for cooling circulating water, and a static pressure distribution chamber connecting the inlet and outlet channels; a distribution plate, centrally fixedly disposed within the static pressure distribution chamber, abutting against the top and bottom walls of the static pressure distribution chamber to divide the static pressure distribution chamber into at least two equal-volume distribution chambers; wherein the inlet channel includes a first end and a second end, the first end extending into the static pressure distribution chamber, and arranged such that at least a portion of the first end is inclined towards the top wall of the static pressure distribution chamber. This invention can minimize the total pipe resistance of the cooling water system while ensuring equal water flow distribution on both sides of the cooling tower.

[0004] The aforementioned patent documents, in conjunction with existing technology, reveal the following shortcomings of existing maintenance platforms for parallel-installed cooling tower groups:

[0005] In existing technologies, motor replacement typically involves the assistance of large hoisting equipment or manual disassembly and transportation, using truck cranes or tower cranes to lift the old motor off the tower. However, due to factors such as narrow roof space and obstructions from surrounding pipelines, cranes often cannot approach the work area. This is especially true for cooling towers installed in parallel, where space utilization is even smaller, leading to inconvenience in disassembly and assembly. Utility Model Content

[0006] In order to overcome the shortcomings of the existing technology, this utility model provides a maintenance platform for parallel-installed cooling tower groups, which solves the problem of maintenance platforms for parallel-installed cooling tower groups.

[0007] The first aspect of this utility model is to provide a maintenance platform for a parallel-installed cooling tower group, used for maintaining multiple cooling tower bodies arranged in parallel. Each cooling tower body is equipped with a motor to be maintained. The platform includes a horizontal support assembly, a horizontal moving assembly, and a vertical moving assembly. The horizontal support assembly includes a horizontally reinforced upright and a horizontally moving winch. The top of the horizontally reinforced upright is provided with a horizontally extending rail, which is located on the upper part of the multiple cooling tower bodies. The horizontal moving assembly includes a horizontally moving frame and a vertically moving winch fixed to the end of the horizontally moving frame. The horizontally moving frame includes two top extending rails and a main frame. The lower part of the main frame is provided with multiple bottom rollers. The top extending rails are located on the top of the main frame. The guide rail is connected to the main frame by inclined support bars, and the lower part of the top extension rail forms a lower clearance space for the motor. The lateral moving winch drives the bottom rollers to roll along the lateral extension rail, causing the lateral moving frame to move laterally. The vertical moving assembly includes a top moving platform, a top winch, and a hoisting assembly. The lower part of the top moving platform is provided with multiple lower rollers that slide along the top extension rail. The top winch is fixed to the top moving platform and drives the hoisting assembly to move up and down. After the lateral moving winch operates and moves the lateral moving assembly to the corresponding position, the hoisting assembly hoists the motor. The vertical moving winch drives the vertical moving assembly to the lower clearance space, and the top winch drives the hoisting assembly to raise and lower the motor.

[0008] In a first aspect of this utility model, as a preferred embodiment, the hoisting assembly includes a connecting rope, a connecting rod, and two end hanging ropes. The connecting rod is connected to the connecting rope, and the two end hanging ropes are disposed at both ends of the connecting rod.

[0009] In a first aspect of this utility model, as a preferred embodiment, the top winch includes a winch body, a rotating roller, a winding rope, and a hook disposed at the end of the winding rope, the hook being connected to the connecting rope.

[0010] In a first aspect of this utility model, as a preferred embodiment, the connecting rope and the connecting rod form an obtuse triangle.

[0011] In a preferred embodiment of the first aspect of this utility model, a lower hook is provided at the lower part of the end hanging rope.

[0012] In a first aspect of this utility model, as a preferred embodiment, the extension direction of the end hanging rope is perpendicular to the connecting rod.

[0013] In a first aspect of this utility model, as a preferred embodiment, the end of the transverse moving winch is provided with a first triangular piece for fixing.

[0014] In a first aspect of this utility model, as a preferred embodiment, the end of the vertically moving winch is provided with a second triangular piece for fixing.

[0015] In a preferred embodiment of the first aspect of this utility model, a top protrusion is provided in the middle of the top moving platform.

[0016] In a preferred embodiment of the first aspect of this utility model, the transversely weighted upright is provided with diagonal reinforcing ribs.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] The lateral extension rails are located on the upper part of multiple cooling tower bodies; the lateral movement assembly includes a lateral movement frame and a vertical movement winch fixed to the end of the lateral movement frame. The lateral movement frame includes two top extension rails and a main frame. Multiple bottom rollers are provided on the lower part of the main frame. The top extension rails are located on the top of the main frame and are connected to the main frame by inclined support bars. The lower part of the top extension rails forms a clearance space below the motor. The lateral movement winch drives the bottom rollers to roll along the lateral extension rails. The system allows the horizontal moving frame to move laterally. The vertical moving component includes a top moving platform, a top winch, and a hoisting assembly. The top moving platform has multiple lower rollers that slide along a top extension track. The top winch is fixed to the top moving platform and drives the hoisting assembly to move up and down. After the horizontal moving winch moves the horizontal moving component to the appropriate position, the hoisting assembly hoists the motor. The vertical moving winch then moves the vertical moving component to a lower clearance space, and the top winch drives the hoisting assembly to raise and lower the motor. By employing the coordinated operation of the horizontal support assembly, the horizontal moving component, and the vertical moving component, flexible movement in three directions is possible, while saving top space and providing a lower clearance space for the motor's descent, thus solving the problem of inconvenient maintenance for parallel-installed cooling tower groups.
