Description

Technical Field

[0001] This utility model relates to the field of equipment maintenance technology, and more specifically, to a device for the maintenance and repair of circulating water cooling towers. Background Technology

[0002] A circulating water cooling tower consists of multiple cooling towers, with walkways around its perimeter for workers to perform routine inspections and maintenance. For inspections and maintenance of higher sections of the cooling tower, workers often use simple ladders, which poses safety risks and limits the available workspace. This frequently results in equipment damage or injuries, causing losses and delays.

[0003] Traditional maintenance racks require a large floor area and have limited mobility. When there is insufficient operating space for maintenance inside the circulating water cooling tower, and maintenance racks need to be built on concrete beams, traditional maintenance racks require each cooling tower to be equipped with a maintenance device, which increases equipment costs and wastes resources.

[0004] In summary, how to provide a maintenance rack device that is easy to move and transport according to the maintenance location is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

Detailed Implementation

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] The core of this utility model is to provide a circulating water cooling tower inspection and maintenance device that is easy to transport and can be used for inspection and maintenance of different cooling towers, thereby reducing maintenance costs.

[0041] Please refer to Figures 1-5 A maintenance and repair device for a circulating water cooling tower includes two support ladder frames 1, two movable bases 2, and a stabilizing mechanism 4. The two support ladder frames 1 are arranged in a V-shape, and several inner side steps 101 are evenly distributed on the support ladder frames 1. The two movable bases 2 are respectively fixed to the bottom of the two support ladder frames 1, and at least two casters 3 are installed on the movable bases 2. The stabilizing mechanism 4 is located on both sides of the support ladder frames 1 and is used to provide lateral support to the support ladder frames 1. The stabilizing mechanism 4 can be retracted.

[0042] In use, the two supporting ladder frames 1 are arranged in a V-shape, forming a triangular structure with the supporting surface, which helps improve stability during use. Several inner step beams 101 are evenly distributed on the supporting ladder frames 1 to facilitate worker climbing. Two movable bases 2 are fixed to the bottom of the two supporting ladder frames 1 respectively. At least two casters 3 are installed on the movable bases 2. Through the casters 3 on the two movable bases 2, workers can easily move the supporting ladder frames 1 according to the maintenance position, improving the convenience of movement and transportation. At the same time, the stabilizing mechanism 4 is located on both sides of the supporting ladder frames 1 and is used to provide lateral support for the supporting ladder frames 1, improving the safety factor and increasing the efficiency of maintenance. The movement direction can be adjusted by using the casters 3 and the folding of the stabilizing mechanism 4, so that the maintenance device can move in extremely narrow walkway spaces. It is suitable for use in many series-connected cooling towers and is suitable for different maintenance locations. It does not require extra personnel to support and assist the maintenance ladder, reducing manpower.

[0043] It should be noted that in this embodiment of the utility model, the supporting ladder frame and the movable base 2 are fixedly connected by welding.

[0044] In addition, the movable base 2 in this embodiment of the invention can adopt a rod-shaped structure to further reduce the footprint of the device.

[0045] In addition, in this embodiment of the invention, the connection between the two supporting ladder frames 1 can be made by hinge, which makes it easy to fold up the device, reduces the footprint of the device, and facilitates the movement of the device in extremely narrow walkway spaces.

[0046] Please refer to Figures 1-5 To further improve the stability of the device during use, some embodiments also include a track 5. The track 5 is installed on both sides of the cooling tower to be inspected. The casters 3 on the two movable bases 2 achieve directional sliding through the track 5. That is, by inserting the casters 3 into the grooves of the track 5, it is possible to facilitate the movement of the device and to improve the support stability of the device during construction.

[0047] In practical use, the support base of the circulating water cooling tower is a frame structure, which limits the area available for placing the maintenance rack. In addition, the circulating water cooling tower has many cooling modules and is relatively tall. Adjacent cooling modules are only connected by walkways. When performing maintenance on a single cooling module, in order to facilitate the pushing and pulling of the circulating water cooling tower maintenance device, rails 5 can be pre-arranged on the concrete beam. Uneven concrete surfaces can be leveled with pads. The rails 5 can be made of steel and fixed to the concrete beam with expansion bolts. The circulating water cooling tower maintenance device is placed on the rails 5 and pushed to the required maintenance position. Corresponding rails 5 are set on the walkways to guide the device as it moves to different inspection rails 5.

[0048] It should be noted that the universal wheel 3 in this embodiment of the present invention has a self-locking function.

[0049] Please refer to Figures 1-5 In some embodiments, the stabilizing mechanism 4 includes a support beam 402, which is hinged to the movable base 2 by a locking bolt 404. When the locking bolt 404 is tightened, the support beam 402 and the movable base 2 are fixedly connected. That is, the lateral distance of the movable base 2 is increased by the support beam 402, thereby improving the stability of the support ladder frame 1 during use. At the same time, the locking bolt 404 is used to lock the hinged position of the support beam 402 and the movable base 2. When the hinged support beam 402 is not in use, it is moved towards the support ladder frame 1 to achieve the folding of the support beam 402, which can further facilitate the user to move the device.

[0050] Optionally, in some embodiments, the support beam 402 can be slidably mounted on the movable base 2, that is, a groove is provided on the movable base 2 and the support beam 402 is placed in the groove. When in use, the support beam 402 can be pulled out of the movable base 2 to achieve the supporting effect of the ladder frame 1.

[0051] Please continue to refer to this. Figures 1-5 In some embodiments, the stabilizing mechanism 4 also includes a directional wheel 403, which is installed at the bottom of the support beam 402. The directional wheel 403 not only supports the support beam 402, but also controls the movement direction of the entire device. When the directional wheel 403 moves within the track 5, it helps to further improve the positioning effect of the device.

[0052] Please continue to refer to this. Figures 1-5 In some embodiments, the fixing mechanism further includes a side support rod 401. One end of the side support rod 401 is hinged to the supporting ladder frame 1, and the other end of the side support rod 401 is detachably connected to the supporting crossbeam 402 by bolts. That is, the side support rod 401, the supporting crossbeam 402 and the supporting ladder frame 1 cooperate to form a triangular structure, thereby further improving the support effect of the supporting ladder frame 1 and improving the stability of the supporting ladder frame 1 during use. At the same time, the detachable nature of the side support rod 401 and the supporting crossbeam 402 allows the side support rod 401 to be conveniently stored when not in use.

[0053] Optionally, in some embodiments, a slot may be provided on the support beam 402, so that the side support rod 401 is fixed to the support beam 402 when it is located inside the slot.

[0054] Optionally, in some embodiments, the side support rod 401 adopts a telescopic structure, that is, it adopts a two-section rod, which achieves the function of storage and support through its extension and retraction.

[0055] Optionally, in order to facilitate the storage of the side support rod 401 and the support beam 402, in some embodiments, the support ladder frame 1 is provided with a fixing member for fixing the side support rod 401 and the support beam 402.

[0056] Alternatively, in some embodiments, the fasteners may be implemented using a fixing rope, which secures the support beam 402 and the side support rod 401 to the support ladder frame 1.

[0057] Optionally, in some embodiments, the fasteners can be fastened by snap-fit, that is, snap-fit ​​is installed on the support ladder frame 1, and the support beam 402 and the side support rod 401 are fixed to the support ladder frame 1 by snapping the crossbeam and the side support rod 401 into the snap-fit.

[0058] Optionally, in some embodiments, the fasteners can be magnets, that is, magnets are installed on the support ladder frame 1, and the crossbeams and side support rods 401 are both made of iron. The magnets attract the crossbeams and side support rods 401, thereby fixing the crossbeams and side support rods 401, which is more convenient and faster.

[0059] Please refer to Figures 1-5In some embodiments, an inspection platform 6 is also included. The inspection platform 6 is detachably installed between two supporting ladder frames 1. The inspection platform 6 provides a maintenance position for workers to facilitate the workers to inspect the top of the cooling tower. The inspection platform 6 is detachably connected, so that different sizes of inspection platforms 6 can be replaced according to different maintenance environments to meet the usage requirements of different environments.

[0060] Please refer to Figures 1-5 In some embodiments, a protective component 7 is also included, which includes a plurality of side guard bars 704 installed on both sides of the supporting ladder frame 1. That is, the side guard bars 704 protect workers during the maintenance climbing process, thereby further improving the safety factor.

[0061] Please continue to refer to this. Figures 1-5 In some embodiments, the protective component 7 also includes a plurality of outer step beams 701, which are installed on the side guard rod 704 and distributed along the length of the support ladder frame 1. That is, the outer step beams 701 are provided on the side where the two sets of inner step beams 101 are far apart, so as to provide standing support for workers when working on the support ladder frame 1, which is conducive to further improving the safety of the device during use.

[0062] It should be noted that the outer step beams 701 in this embodiment of the present invention can be arranged in different quantities and at different intervals according to the usage requirements.

[0063] Please refer to Figures 1-5 In some embodiments, the protective component 7 further includes two telescopic guardrails 703 and guardrail sleeves 702. The two telescopic guardrails 703 have an E-shaped structure and are located on both sides of the maintenance platform 6. The guardrail sleeves 702 are installed on the maintenance platform 6. The telescopic guardrails 703 can slide within the guardrail sleeves 702. That is, the two sets of telescopic guardrails 703 protect both sides of the maintenance platform 6, improving safety during maintenance. At the same time, the telescopic guardrails 703 are slidably installed within the guardrail sleeves 702, so their height can be adjusted by sliding to meet the usage requirements of different heights. In addition, the overall height of the device is reduced when the device is being transported, which is conducive to the transport of the device.

[0064] In other words, the key point of this utility model embodiment is that: through a number of casters 3 on the two movable bases 2, workers can easily move the support ladder frame 1 according to the maintenance location, improving the convenience of movement and transportation. At the same time, the stabilizing mechanism 4 is located on both sides of the support ladder frame 1 and is used to provide lateral support to the support ladder frame 1, thereby improving the safety factor and maintenance efficiency. By using the casters 3 to adjust the direction of movement and the slewing of the stabilizing mechanism 4, the maintenance device can move in extremely narrow walkway spaces, making it suitable for use in many series-connected cooling towers and applicable to different maintenance locations. It does not require extra personnel to support and assist the maintenance ladder, reducing manpower.
