Description
Technical field
The utility model about a kind of cooling tower inner wall construction equipment, particularly a kind of equipment being applied to the construction of natural ventilation double-curve cooling column inner wall anti-corrosive, anticorrosion maintenance and maintenance process.
Background technology
Cooling stack is double-curve cooling column, is mainly used in thermal powerplant and nuclear power plant.Cooling stack is categorized as common cooling tower, seawater cooling tower, exhaust cooling tower.
At present, domestic seawater cooling tower and exhaust cooling tower application more and more extensively, and when cooling tower anti-corrosion construction, anticorrosion maintenance and inwall seepage point are keeped in repair, mainly adopt common Lifting basket to construct.Common hanging basket mainly contains following a few part composition.
(1) suspension platform: suspension platform is the work-yard of workmen, he combines by being connected with bolt with elevator mounting frame four parts at the bottom of height railing, basket.
(2) gig: gig is the power part of suspension platform, adopts electronic climbing type structure.Gig is driven by electromagnetic braking threephase asynchronous machine, drives steel wire rope conveyer structure to make gig along load cable up-and-down movement after turbine and worm and a pair gear reduction, thus drives suspension platform to rise or decline.
(3) safety lock: safety lock is the safety guard of suspension platform, when fracture occurs suddenly load cable or suspension platform tilts to certain angle, can lock firm safety steel cable by fast speed automatically, ensures that suspension platform does not fall or continues to tilt.
(4) suspended structure: hitch is set up in building top, suspended in midair the device of suspension platform by steel rope.
(5) electric control box: electric control box is used to the parts controlling suspension platform motion, and main element is arranged on one piece of insulcrete, on omnipotent pole changer, power light, start button and emergency stop button device boxboard door-plate.
Above-mentioned parts hanging basket can carry out lift work after professional installs.Be directed to double-curve cooling column, after hanging basket is installed, hanging basket can not near cooling tower curve regions.
Utility model content
Namely the technical matters that the utility model solves is providing a kind of equipment being applied to the construction of natural ventilation double-curve cooling column inner wall anti-corrosive, anticorrosion maintenance and maintenance process.
The technological means that the utility model adopts is as described below.
Be applied to an equipment for natural ventilation double-curve cooling column inner wall construction, comprise hanging basket, gig is established at the two ends, left and right of this hanging basket, and hanging basket side arranges secondary frame, and this secondary frame establishes at least 1 stretching actuator in contrast to the side of hanging basket.Inner wall of tower top and bottom establish top sheave and lower sheave respectively.Also comprise at least 2 ropes, it is each passed through gig, top sheave, stretching actuator and lower sheave, and gig drives hanging basket to move up and down, and stretching actuator tension rope strap moves hanging basket and secondary frame near inner wall of tower.
The vertical section of described hanging basket secondary frame is rectangle, parallelogram or trapezoidal.
Described stretching actuator quantity is 1,2 or multiple, and stretching actuator is controlled by electric control box.
Described rope is steel rope.
Described top sheave is fixed by suspended structure.
Described secondary frame establishes stretching actuator side to be also provided with at least 1 roller.
The beneficial effect that the utility model produces is as follows.
In natural ventilation double-curve cooling column inner wall construction, by increasing the device of the relative position changing hanging basket and inner wall of tower, actv. changes the limitation that hanging basket only can move up and down, and mechanical equipment is used more convenient, and safer being applied in double-curve cooling column inner wall construction.
Accompanying drawing explanation
Fig. 1 is the amplification assumption diagram of hanging basket and secondary frame in the utility model.
Fig. 2 is integral structure schematic diagram of the present utility model.
Detailed description of the invention
A kind of equipment being applied to natural ventilation double-curve cooling column inner wall construction of the utility model protection.As shown in Figure 1, comprise hanging basket 1, gig 3 is established at the two ends, left and right of this hanging basket 1 respectively, and hanging basket 1 side arranges secondary frame 2, and at least 1 stretching actuator 4 is established in the side in contrast to hanging basket 1 on this secondary frame 2.Be rectangle, parallelogram or trapezoidal according to the vertical section of the described secondary frame 4 of reality, or be designed to other shapes according to actual conditions.
Shown in composition graphs 1 and Fig. 2, inner wall of tower top and bottom establish top sheave 6 and lower sheave 7 respectively, and top sheave 6 is fixed on inner wall of tower by suspended structure, and suspended structure is the prior aries that the art personnel alternative uses, and no longer specifically limits.Also comprise at least 2 ropes 5, consider that this rope can adopt steel rope from safety perspective, it, through described gig 3, top sheave 6, stretching actuator 4 and lower sheave 7, forms 1 steel rope loop.Stretching actuator can adopt electric control box to control (not shown), sets its position according to actual conditions.Separately, secondary frame 2 establishes stretching actuator 4 side also can be provided with at least 1 roller 8, stretching actuator 4 and roller 8 can be located at the upper and lower end of secondary frame 2 respectively, and this roller 8 can avoid the friction between steel rope and secondary frame, promote the convenience and safety that use.
Based on said structure, gig 3 can drive hanging basket 1 to move up and down, and stretching actuator can move hanging basket and secondary frame near inner wall of tower by tension rope strap.Separately, other existing installations be installed on hanging basket are applicable equally, as suspended structure can connect the safety etc. that safety rope ensures workmen.
As shown in Figure 2, during actual use, suspension gear and tower bottom are respectively installed, lower sheave, and steel rope can slide on pulley.Steel rope is successively through top sheave, gig and lower sheave, and two is through in stretching actuator 4.
By the running of gig, hanging basket is driven to move up and down.When needs by hanging basket near double-curve cooling column inwall time, started by stretching actuator 4, steel rope is strained, utilize the pulling force of steel rope, hanging basket 1 can near natural ventilation double-curve cooling column inwall, thus constructability personnel safeguard inner wall of tower.
In the present embodiment; hanging basket is done a complementary framework; be generally positioned at the opposite side of hanging basket relative to inner wall of tower; it can improve the application force of steel rope; hanging basket can be allowed more easily near double-curve cooling column inwall; shock attenuation device can be set in the nearly inner wall of tower side of hanging basket according to the situation that reality uses, play protection hanging basket and reduce the effect of colliding with.Stretching actuator adopts electric control box to control, and when stretching actuator stretches, steel rope shortens, and steel rope produces stress makes hanging basket close to cooling tower inwall.
