Description

Technical Field

[0001] The present invention relates to the technical field of construction devices for water-cooling cooling towers, and particularly to a construction device for repairing the herringbone columns of cooling towers. Background Art

[0002] The herringbone columns of cooling towers, as the core load-bearing components at the bottom of cooling towers, are formed by the intersection of two cylinders inclined at a specific angle to form a herringbone structure, and are evenly distributed at the bottom of the cooling tower shell in a circular array. Their structural design not only needs to bear the self-weight of the upper structure of the cooling tower, wind loads, and dynamic loads generated by internal thermal cycles, but also needs to ensure the stability of the tower body under complex working conditions. During long-term operation, the herringbone columns continuously deteriorate due to continuous exposure to the external environment; at the same time, the vibration loads generated during the operation of the cooling tower and the additional stresses generated by uneven settlement of the foundation further exacerbate the damage to the structure of the herringbone columns.

[0003] Currently, traditional scaffolding is still the mainstream method for building construction platforms during the repair of herringbone columns. However, since the inclination angle of the herringbone columns is usually between 45° and 60°, and they are radially distributed along the outer periphery of the tower, it is difficult for the traditional vertical scaffolding system to accurately match the inclination direction of the herringbone columns. And in actual construction, workers need to climb and work in mid-air repeatedly, which not only significantly reduces the construction efficiency but also greatly increases safety risks such as falling from a height and being struck by objects. Therefore, developing a construction device that can adapt to the inclination angle of the herringbone columns and provide a stable operation space has become a key technological breakthrough point for ensuring the operation safety and efficiency of cooling towers. Summary of the Invention

[0004] The purpose of the present application is to provide a construction device for repairing the herringbone columns of cooling towers, which can adjust its own inclination angle to adapt to the inclination angle of the herringbone columns of the cooling tower, and is provided with a workbench, so that workers do not need to work in mid-air, effectively ensuring safety.

[0005] To achieve the above purpose, a construction device for repairing the herringbone columns of cooling towers adopted by the present application includes: a base, a support structure, a lifting structure, and a bearing platform;

[0006] The support structure includes a linear actuator and a support rod. The bottom end of the linear actuator is rotatably installed on the top surface of the base, and the bottom end of the support rod is connected to the power output end of the linear actuator;

[0007] The lifting structure includes: a mounting bracket, a lead screw, and a motor;

[0008] The bottom end of the mounting bracket is rotatably connected to the top surface of the base and is spaced apart from the linear drive. The top end of the mounting bracket is rotatably connected to the top end of the support rod. The linear drive can drive the support rod to move linearly along its axis, thereby adjusting the tilt angle of the mounting bracket relative to the base;

[0009] A through groove extending along the length direction of the mounting bracket is provided on the mounting bracket. The lead screw is arranged in the through groove. The motor is installed at the bottom of the mounting bracket. The bottom end of the lead screw is connected to the power output end of the motor, and the top end is rotatably connected to the mounting bracket. The carrier table is slidably installed on the mounting bracket, and the carrier table is screwed to the lead screw. The motor can drive the lead screw to rotate, thereby driving the carrier table to slide along the through groove.

[0010] As a preferred technical solution, the linear drive is any one of an electric telescopic device, a hydraulic telescopic device, and a pneumatic telescopic device.

[0011] As a preferred technical solution, the mounting bracket includes a top plate and side plates symmetrically arranged on both sides of the top plate. The top end of the side plate is fixedly connected to the top plate, and the bottom end is rotatably connected to the base. The through groove is jointly defined between the two side plates and the top plate. The support rod is rotatably connected to the top plate.

[0012] As a preferred technical solution, the construction device for repairing the herringbone columns of the cooling tower further includes a first rotating shaft. The first rotating shaft is installed on the base, and the side plate is rotatably connected to the first rotating shaft to realize the rotational connection between the mounting bracket and the base.

[0013] As a preferred technical solution, the construction device for repairing the herringbone columns of the cooling tower further includes a second rotating shaft. The second rotating shaft is installed on the top plate, and the support rod is rotatably connected to the top plate through the second rotating shaft.

[0014] As a preferred technical solution, a notch for accommodating the herringbone column is provided on one side of the carrier table.

[0015] As a preferred technical solution, a protective tube is installed on the top of the carrier table, and the protective tube is screwed to the outer periphery of the lead screw.

[0016] As a preferred technical solution, the construction device for repairing the herringbone columns of the cooling tower further includes a guardrail, and the guardrail is fixedly connected to the outer peripheral side of the top of the carrier table.

[0017] As a preferred technical solution, the construction device for repairing the herringbone columns of the cooling tower further includes a reinforcement bracket, and the reinforcement bracket is detachably connected to the bottom surface of the carrier table.

[0018] As a preferred technical solution, a plurality of through holes penetrating the upper and lower surfaces of the base are provided on the base.

[0019] When the construction device for repairing the chevron columns of a cooling tower in the present application is in use, the staff stands on the loading platform, starts the linear driver to make the inclination angle of the mounting bracket adapt to the inclination angle of the chevron column, and then starts the motor to drive the screw rod to rotate, so that the loading platform moves along the length direction of the mounting bracket until the loading platform reaches the working position and the motor is turned off. The staff can then carry out the repair work on the chevron column. Among them, the linear driver, the support rod, the mounting bracket and the base jointly form a stable triangular support structure. By adjusting the telescopic length of the linear driver to drive the support rod to telescopically move along its axis, the mounting bracket rotates synchronously to change the included angle between it and the base, realizing the adjustment of the inclination angle of the mounting bracket to adapt to the inclination angles of different chevron columns of the cooling tower. This device can well adapt to the repair work of chevron columns with different inclination angles, and at the same time can provide a stable and safe operation platform for the staff. The overall structure is simple and has good stability, which is beneficial to ensuring safety. Description of the Drawings

[0026] Please refer to Figure 1 , a construction device for repairing the herringbone columns of a cooling tower provided by an embodiment of the present application, comprising: a base 1, a support structure 2, a lifting structure 3, and a carrier table 4;

[0027] The support structure 2 includes a linear driver 21 and a support rod 22. The bottom end of the linear driver 21 is rotatably installed on the top surface of the base 1, and the bottom end of the support rod 22 is connected to the power output end of the linear driver 21;

[0028] The lifting structure 3 includes: a mounting bracket 31, a lead screw 32, and a motor 33;

[0029] The bottom end of the mounting bracket 31 is rotatably connected to the top surface of the base 1 and is spaced from the linear driver 21. The top end of the mounting bracket 31 is rotatably connected to the top end of the support rod 22. The linear driver 21 can drive the support rod 22 to move linearly along its axis, thereby adjusting the inclination angle of the mounting bracket 31 relative to the base 1;

[0030] A through groove 310 extending along the length direction of the mounting bracket 31 is provided on the mounting bracket 31. The lead screw 32 is disposed in the through groove 310. The motor 33 is installed at the bottom of the mounting bracket 31. The bottom end of the lead screw 32 is connected to the power output end of the motor 33, and the top end is rotatably connected to the mounting bracket 31. The carrier table 4 is slidably installed on the mounting bracket 31, and the carrier table 4 is screwed to the lead screw 32. The motor 33 can drive the lead screw 32 to rotate, thereby driving the carrier table 4 to slide along the through groove 310.

[0031] In this embodiment, the base 1, the support structure 2, and the lifting structure 3 together form a triangular structure to form a stable support. And through the telescopic movement of the support structure 2, the lifting structure 3 can be driven to rotate to adjust its tilt angle relative to the base 1, so that the device can flexibly adapt to the herringbone columns of cooling towers to be repaired at different angles, enhance the adaptability of the device to different working conditions, and expand the scope of use. In addition, the lifting structure 3 is composed of a mounting bracket 31, a lead screw 32, and a motor 33. The carrier table 4 is slidably disposed on the mounting bracket 31 and is screwed to the lead screw 32. Among them, the motor 33 is used to drive the lead screw 32 to rotate. A through groove 310 is formed in the mounting bracket 31 along its length direction, and the lead screw 32 is correspondingly arranged in the through groove 310, which is beneficial to protecting the lead screw 32 and preventing damage to the lead screw 32 caused by bumps; at the same time, the lead screw 32 drives the carrier table 4 to slide up and down along the through groove 310 to move the carrier table 4 to the working position, facilitating the staff to repair the herringbone column, and the overall structure is stable, which is beneficial to ensuring the personal safety of the staff.

[0032] In some embodiments, the linear driver 21 is any one of an electric telescopic device, a hydraulic telescopic device, and a pneumatic telescopic device. Using a telescopic device to adjust the length of the support structure 2 is relatively simple. There is no need for a complicated process of disassembling or replacing components. Only by controlling the telescopic action of the telescopic device can the angle between the mounting bracket 31 and the base 1 be changed, saving operation time and labor costs and improving work efficiency. And the user can select a suitable telescopic device according to the actual situation. Among them, the electric telescopic device has a relatively simple structure, and the installation process is relatively convenient. There is no need for a complicated pipeline system to transmit hydraulic oil or compressed air, and its maintenance cost is relatively low; the hydraulic system can generate a large driving force and is suitable for occasions where heavy objects need to be lifted or pushed. Moreover, the incompressibility of the hydraulic oil makes the hydraulic telescopic device have good stability and buffering performance during operation. It can still maintain a relatively uniform movement speed under large load changes, reducing vibration and impact; the pneumatic telescopic device uses compressed air as the power source. The compressibility of air enables it to respond quickly when starting and stopping, with rapid action. And the pneumatic system usually has a relatively low working pressure, and air has good elasticity. Even when a fault occurs in the system, it is not easy to have dangerous high-pressure leaks or explosions.

[0033] In some embodiments, the mounting bracket 31 includes a top plate 311 and side plates 312 symmetrically arranged on both sides of the top plate 311. The top end of the side plate 312 is fixedly connected to the top plate 311, and the bottom end is rotatably connected to the base 1. The through groove 310 is jointly defined among the two side plates 312 and the top plate 311, and the support rod 22 is rotatably connected to the top plate 311. Among them, the through groove 310 is jointly defined among the two side plates 312 and the top plate 311, and the lead screw 32 is arranged in the through groove 310, so as to form protection around the outer circumference of the lead screw 32, prevent the lead screw 32 from causing harm to personnel, and also prevent the lead screw 32 from being damaged due to friction and collision with other structures, which is beneficial to extending the service life of the lead screw 32.

[0034] In some embodiments, the construction device for repairing the chevron columns of the cooling tower further includes a first rotating shaft, the first rotating shaft is installed on the base 1, and the side plate 312 is rotatably connected to the first rotating shaft to realize the rotational connection between the mounting bracket 31 and the base 1. At the same time, in some embodiments, the construction device for repairing the chevron columns of the cooling tower further includes a second rotating shaft, the second rotating shaft is installed on the top plate 311, and the support rod 22 is rotatably connected to the top plate 311 through the second rotating shaft.

[0035] A first rotating shaft and a second rotating shaft are provided. On the one hand, the flexibility of angle adjustment can be significantly improved. The first rotating shaft allows the bottom end of the mounting bracket 31 to rotate around the base 1, and the second rotating shaft enables relative rotation between the support rod 22 and the mounting bracket 31. The cooperation of the two makes the mounting bracket 31 able to flexibly adjust the angle in multiple dimensions. In this way, it can better adapt to the hyperbolic cooling tower columns at various angles and positions, greatly expanding the applicable range of the device. At the same time, when repairing the hyperbolic cooling tower columns, it is often necessary to precisely adjust the angle of the mounting bracket 31. The setting of the two rotating shafts allows the operator to finely control the angle of the mounting bracket 31 by fine-tuning the telescopic device and controlling the rotation of the two rotating shafts, so as to ensure that the device can accurately fit the hyperbolic cooling tower column to be repaired and improve the repair accuracy. On the other hand, setting the rotating shafts can enhance the structural stability and reliability. When the telescopic device adjusts the length of the support structure 2 to drive the movement of the mounting bracket 31, the first rotating shaft and the second rotating shaft can disperse the stress generated during the movement of the device, avoid damage to components caused by local stress concentration, extend the service life of the device, and ensure the stability and reliability of the structure during long-term use. Moreover, the first rotating shaft, the second rotating shaft, the telescopic device, the support rod 22, and the mounting bracket 31 together form a stable mechanical structure. Each component cooperates with each other to jointly bear the load during operation, making the entire device more stable, reducing the possibility of shaking and deviation, and providing a solid foundation for the repair work. In addition, this connection method makes it easier to disassemble each component. When a component fails or needs to be maintained, the operator can quickly separate it from the device for repair or replacement, thereby reducing the repair time and cost.

[0036] In some embodiments, a notch 41 for accommodating the hyperbolic cooling tower column is formed on one side of the bearing platform 4. During the construction process, the existence of the notch 41 can provide clear guidance for the installation of the hyperbolic cooling tower column. Construction workers can operate more conveniently, reduce the construction difficulty, and improve the construction efficiency. At the same time, it is also beneficial for subsequent inspection and maintenance work, facilitating the inspection and repair of the connection part between the hyperbolic cooling tower column and the bearing platform 4.

[0037] In some embodiments, a protective tube 42 is installed on the top of the bearing platform 4, and the protective tube 42 is screwed onto the outer periphery of the lead screw 32. The protective tube 42 can isolate the lead screw 32 from the bearing platform 4, prevent the rotation of the lead screw 32 from causing harm to the staff on the bearing platform 4, and improve the use safety of the device.

[0038] In some embodiments, the construction device for repairing the herringbone columns of the cooling tower further includes a guardrail 43, which is fixedly connected to the outer peripheral side of the top of the bearing platform 4. The guardrail 43 can prevent people from accidentally falling from the bearing platform 4. Especially in the case of working at heights or there being dangerous areas around the bearing platform 4, it can effectively avoid the occurrence of personal injury accidents and provide reliable safety protection for the personnel working on the bearing platform 4. The guardrail 43 can also prevent items, tools, etc. on the bearing platform 4 from falling to the lower area, avoiding damage to personnel and equipment below, helping to maintain the safety order of the construction site and reducing potential safety hazards. Additionally, in some cases, the staff can lean or support briefly on the guardrail 43. For example, when performing some operations that require body stability, the guardrail 43 can provide certain auxiliary support and enhance the stability of the personnel's operations.

[0039] Please refer to Figure 2 , in some embodiments, the construction device for repairing the herringbone columns of the cooling tower further includes a reinforcement bracket 44, which is detachably connected to the bottom surface of the bearing platform 4. The reinforcement bracket 44 can share the load borne by the bearing platform 4, transfer the weight more evenly to the screw rods 32 and the mounting brackets 31, improve the load-bearing capacity of the bearing platform 4 for heavy objects, enable it to withstand greater pressure and load, and prevent the bearing platform 4 from deforming or being damaged due to overload. The reinforcement bracket 44 can also enhance the overall structural stability of the bearing platform 4, reducing shaking, vibration, and displacement during use.

[0040] In some embodiments, a number of through holes 11 are provided in the base 1, which penetrate its upper and lower surfaces. Without affecting the structural strength of the base 1, the presence of the through holes 11 reduces the amount of material used for the base 1, thereby reducing the weight of the base 1, which can lower the transportation cost and manpower consumption.

[0041] In summary, the construction device for repairing the herringbone columns of the cooling tower provided in this embodiment can be applicable to the repair work of the herringbone columns of cooling towers with different inclination angles, has a simple overall structure, strong structural stability, and can provide a safe operation platform for the staff.
