Description

Technical Field

[0001] The utility model relates to the technical field of welding construction, in particular to a water tank welding construction operation platform. Background Art

[0002] The boiler water tank is an important component of the boiler system. It is shaped like an original cylindrical structure and is mainly used to store and pre-treat water supplied to the boiler. The boiler water tank is not only used to store make-up water and recovered condensate, but also uses various designs and technical means to ensure that the water quality and water quantity meet the needs of the boiler, thereby ensuring the efficient operation of the entire system. Therefore, its overall volume is relatively large. In traditional construction, the components on the water tank and the connecting parts of the water tank generally need to be welded using welding technology.

[0003] For example, a supercritical boiler water tank and its manufacturing method are disclosed in the patent document with patent publication number CN102269397B. The main boiler water tank structure is constructed by suspending the water tank, welding spherical heads with pipe joints up and down as the upper and lower heads of the water tank, and other steps to complete the forming of the water tank.

[0004] It can be seen that this cantilever method has unstable factors when performing welding construction, and it is similar to the method of using traditional hanging basket and crane, which has the problems of high machinery cost and low construction efficiency; in addition, for some situations restricted by the site, the distance between multiple water tanks will be small, and the traditional more stable scaffolding method cannot be used for welding construction.

[0005] To this end, the utility model optimizes the existing welding construction problems of multiple boiler water tanks with small spacing, and specially proposes a water tank welding construction work platform that can provide welding work stations for welding workers, so as to better solve the problems existing in the prior art.

[0008] In any of the above schemes, it is preferred that the upper part of each of the vertical steel frames is bent toward one side of the water tank to form a clamping portion, the top of the clamping portion is horizontally arranged, the lower end extends vertically to the interior of the water tank and is vertically arranged, and a guide steel shaft is arranged above the side wall of the water tank, and both ends of the guide steel shaft are movably extended to the through holes on the vertical steel frames on the corresponding two sides and extend to the outside thereof.

[0009] In any of the above schemes, preferably, anti-slip steel sleeves are fixed on the outer side walls at both ends of each of the guide steel shafts.

[0010] In any of the above schemes, it is preferred that a plurality of guide structures are installed on the inner side wall of the vertical section of each of the vertical steel frames at intervals from top to bottom, and each of the inner side walls is movably abutted against the outer side wall of the water tank.

[0016] 1. This water tank welding construction platform can provide a welding construction platform for the welding of large cylindrical boiler water tanks, effectively provide a standing platform for construction workers, and effectively ensure the stability of the entire structure.

[0017] 2. By hooking and positioning the water tank welding construction platform on the upper part and outside of the water tank, the problem of continuously using lifting equipment to lift the construction platform in traditional water tank welding construction can be effectively eliminated, and the frequency of using the lifting equipment is effectively reduced.

DETAILED DESCRIPTION

[0026] The following is a detailed description of the embodiments of the technical solution of the utility model in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the scope of protection of the utility model. Figure 1-Figure 4 as shown in .

[0027] Embodiment 1: A water tank welding construction work platform comprises two vertical steel frames 2 arranged vertically on the outside of a cylindrical water tank 1 to be welded, the two vertical steel frames 2 are arranged at relative intervals, a plurality of climbing beam tubes 3 are arranged at intervals from top to bottom between the two vertical steel frames 2, both ends of each climbing beam tube 3 are respectively fixedly mounted on the corresponding vertical steel frames 2, a protective frame 4 is fixedly welded on the outside of the two vertical steel frames 2, a construction space 5 for workers to pass through is formed between the protective frame 4 and the water tank 1, load-bearing beams 6 are welded at intervals from top to bottom on the frame bodies on the front and rear sides of the protective frame 4, a construction platform 7 is arranged between the two load-bearing beams 6 located at the same level, and the bottom of the construction platform 7 is supported on the top of the corresponding load-bearing beam 6. When installing the water tank welding construction platform, it is only necessary to start the crane to place it on the upper part of the water tank 1 and complete the clamping by the clamping part 201. During the construction process after installation, the crane operation is no longer required. At this time, the construction personnel can climb to the corresponding height by themselves and then climb onto the corresponding construction platform 7 to perform standing construction. Among them, the entire construction platform 7 can provide lateral gripping support for the workers during the construction process, and the stairs formed by the various construction platforms 7 can be used for the operating workers to quickly adjust up and down. When the construction workers stand on the top of the corresponding construction platform 7, the various load-bearing beams 6 can effectively provide stable support for the entire construction platform 7 to ensure the stability of the support during construction.

[0028] In any of the above schemes, preferably, anti-movement plates 8 are fixedly welded to the bottoms of both ends of the construction platform 7, and the inner sides of the anti-movement plates 8 are respectively abutted against the side walls of the corresponding load-bearing beams 6. The two anti-movement plates 8 can limit the lateral movement of the construction platform 7, ensuring that it can effectively limit and prevent deviation under the action of the anti-movement plates 8 cooperating with the corresponding load-bearing beams 6 and the protection frames 4 on both sides.

[0029] In any of the above schemes, it is preferred that the upper part of each of the vertical steel frames 2 is bent toward one side of the water tank 1 to form a clamping part 201, the top of the clamping part 201 is horizontally arranged, and the lower end is vertically extended to the inside of the water tank 1 and is arranged vertically, and a guide steel shaft 9 is arranged above the side wall of the water tank 1, and both ends of the guide steel shaft 9 are movable through the through holes on the vertical steel frames 2 on the corresponding two sides and extend to the outside thereof. The middle outer wall of the guide steel shaft 9 is movably abutted against the top of the water tank 1, so when the entire water tank welding construction work platform moves relative to the water tank 1 under the external force of the construction workers, the guide steel shaft 9 can play a role in guiding and reducing friction; in addition, the top of the guide steel shaft 9 plays a role in supporting during normal construction.

[0030] In any of the above schemes, preferably, an anti-slip steel sleeve 10 is fixed on the outer side walls at both ends of each of the guide steel shafts 9. The anti-slip steel sleeves 10 fixedly installed at both ends can position the ends of the current guide steel shaft 9, effectively preventing the two ends of the guide steel shaft 9 from sliding to both sides, and ensuring the positioning stability of the guide steel shaft 9 when in use.

[0031] In any of the above schemes, it is preferred that a plurality of guide structures are installed at intervals from top to bottom on the inner side walls of the vertical sections of each of the vertical steel frames 2, and each of the inner side walls is movably abutted against the outer side wall of the water tank 1. The guide structure is directly movably abutted against the outer side wall of the water tank 1, which can firstly play a supporting role, and secondly, can play a guiding role when it is necessary to control the displacement of the entire water tank welding construction work platform along the circumference of the water tank 1, thereby reducing the running resistance.

[0032] Embodiment 2: A water tank welding construction work platform comprises two vertical steel frames 2 arranged vertically on the outside of a cylindrical water tank 1 to be welded, the two vertical steel frames 2 are arranged at relative intervals, a plurality of climbing beam tubes 3 are arranged at intervals from top to bottom between the two vertical steel frames 2, both ends of each climbing beam tube 3 are respectively fixedly mounted on the corresponding vertical steel frames 2, a protective frame 4 is fixedly welded on the outside of the two vertical steel frames 2, a construction space 5 for workers to pass through is formed between the protective frame 4 and the water tank 1, load-bearing beams 6 are welded at intervals from top to bottom on the frame bodies on the front and rear sides of the protective frame 4, a construction platform 7 is arranged between the two load-bearing beams 6 located at the same level, and the bottom of the construction platform 7 is supported on the top of the corresponding load-bearing beam 6.

[0033] In any of the above schemes, it is preferred that anti-movement upright plates 8 are fixedly welded to the bottom of both ends of the construction platform 7, and the inner side of each anti-movement upright plate 8 abuts against a side wall of the corresponding load-bearing beam 6.

[0034] The two anti-movement plates 8 can limit the lateral movement of the construction platform 7, ensuring that it can effectively limit and prevent deviation under the action of the anti-movement plates 8 cooperating with the corresponding load-bearing beams 6 and the protective frames 4 on both sides.

[0035] In any of the above schemes, it is preferred that the upper portion of each of the vertical steel frames 2 is bent toward one side of the water tank 1 to form a clamping portion 201, the top of the clamping portion 201 is horizontally arranged, and the lower end extends vertically into the interior of the water tank 1 and is vertically arranged, and a guide steel shaft 9 is arranged above the side wall of the water tank 1, and both ends of the guide steel shaft 9 are movably extended to the through holes on the vertical steel frames 2 on the corresponding two sides and extend to the outside thereof.

[0036] The middle outer wall of the guide steel shaft 9 is movably abutted against the top of the water tank 1. Therefore, when the entire water tank welding construction work platform moves relative to the water tank 1 under the external force of the construction workers, the guide steel shaft 9 can play a guiding and friction reducing role; in addition, during normal construction, the top of the guide steel shaft 9 plays a supporting role.

[0037] In any of the above schemes, preferably, anti-slip steel sleeves 10 are fixed to the outer side walls at both ends of each of the guide steel shafts 9 .

[0038] The anti-slip steel sleeves 10 fixedly installed at both ends can position the ends of the current guide steel shaft 9, effectively preventing the two ends of the guide steel shaft 9 from sliding to both sides, and ensuring the positioning stability of the guide steel shaft 9 when in use.

[0039] In any of the above schemes, it is preferred that a plurality of guide structures are installed on the inner side wall of the vertical section of each of the vertical steel frames 2 at intervals from top to bottom, and each of the inner side walls is movably abutted against the outer side wall of the water tank 1 .

[0040] The guide structure is directly in movably contact with the outer wall of the water tank 1. First, it can play a supporting role. Second, it can play a guiding role when it is necessary to control the entire water tank welding construction work platform to shift along the circumference of the water tank 1, thereby reducing the running resistance.

[0041] In any of the above schemes, it is preferred that the guide structure includes a welding wheel frame 11 vertically fixedly installed on the inner wall of the vertical section of the vertical steel frame 2, and a guide steel wheel 12 is arranged in the installation cavity of the welding wheel frame 11, and both ends of the central axis of the guide steel wheel 12 are movable to the outside of the welding wheel frame 11.

[0042] Each guide structure relies on the corresponding guide steel wheel 12 to complete the abutment with the outer wall of the water tank 1, so that the vertical section of the entire vertical steel frame 2 can be abutted and supported on the outside of the outer wall of the water tank 1, effectively ensuring the stability of the entire vertical steel frame 2 structure; in addition, since each vertical steel frame 2 can reduce friction resistance during displacement under the action of the guide steel wheel 12, the water tank welding construction work platform is ensured to move along the circumferential outer wall of the entire water tank 1 under the force applied by the construction workers in a rolling friction manner. During the movement, the abutment of multiple guide steel wheels 12 with the outer wall of the water tank 1 and the movable abutment of the top guide steel shaft 9 with the top of the water tank 1 are used to reduce the running resistance by rolling friction, thereby ensuring the smoothness of the movement.

[0043] In addition, when manual pushing and shifting is difficult, external auxiliary equipment can also be used to pull and shift it.

[0044] In any of the above solutions, preferably, a lifting ring 13 is fixedly welded on the top of each of the vertical steel frames 2 .

[0045] The provided lifting ring 13 can facilitate the lifting and displacement in cooperation with the external lifting hook when the entire structure is lifted.

[0046] In any of the above solutions, it is preferred that an anti-slip structure 14 is fixedly provided on the top of the construction platform 7 .

[0047] The anti-slip structure 14 can be set as a protective pad or a friction pad as needed, which effectively reduces the probability of construction workers slipping thereon and achieves the purpose of safety protection.

[0048] In any of the above solutions, it is preferred that a plurality of reinforcing rib plates 15 are welded between each of the anti-movement vertical plates 8 and the construction platform 7 .

[0049] Each reinforcing rib plate 15 can enhance the support stability of the entire anti-movement vertical plate 8 and improve the lateral protection effect.

[0050] Specific working principle: When installing the entire water tank welding construction work platform, you only need to start the crane to place it on the upper part of the water tank 1 and rely on the clamping part 201 to complete the clamping. During the construction process after installation, the crane operation is no longer required. At this time, the construction personnel can climb to the corresponding height by themselves and step onto the corresponding construction platform 7 for standing construction.

[0051] The entire construction platform 7 can provide lateral gripping support for workers during the construction process, and at the same time, the stairs formed by the various construction platforms 7 can be used for operating workers to quickly move up and down.

[0052] When construction workers stand on the top of the corresponding construction platform 7, the load-bearing beams 6 can effectively provide stable support for the entire construction platform 7, ensuring the stability of the support during construction; in addition, each guide structure relies on the corresponding guide steel wheel 12 to abut against the outer wall of the water tank 1, so that the vertical section of the entire vertical steel frame 2 can be abutted and supported on the outside of the outer wall of the water tank 1, effectively ensuring the stability of the entire vertical steel frame 2 structure.

[0053] The guide structure cooperates with the corresponding guide steel shaft 9 to facilitate the rapid displacement of the entire platform structure.

[0054] From the above, it can be seen that the present construction platform can provide a welding construction platform 7 for the welding operation of the cylindrical boiler water tank 1, provide a standing platform for the construction workers, and ensure the stability of the entire structure; by hooking and positioning the present water tank welding construction platform on the upper part and the outer side of the water tank 1, it can effectively eliminate the problem of the need to continuously use lifting equipment to lift the construction platform 7 in the traditional water tank 1 welding construction, thereby reducing the frequency of use of the lifting equipment, and only requires the entire water tank welding construction platform to be placed and removed twice; during construction, the water tank welding construction platform can rely on the operator to climb and shift to the top of the construction platform 7 at different heights, effectively completing standing construction operations at different heights; the operator can apply force by grasping the top side wall of the water tank 1, and can slowly shift along the circumference of the water tank 1 under the action of various guide structures and the guide steel shaft 9, thereby completing the construction of the parts to be welded on the water tank 1 in different orientations.

Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above embodiments, or replace some or all of the technical features therein with equivalents.
