Large-scale storage tank external surface construction trailer
The utility model relates to a kind of construction tool, and particularly a kind of trailer of constructing at large-scale storage tank external surface belongs to the instrument for large-scale storage tank construction.
Large Oil Tank, as the carrier of carrying crude oil, requires strict to its build guality.Large Oil Tank is after main body construction completes, also carrying out anticorrosion outside storage tank, welding insulation construction, lay the operations such as heat-preservation cotton insulation, the welding job of heat-preservation cotton bracing ring wherein as examination water before last procedure, welding capacity is larger, and work high above the ground is more frequent.In order to ensure construction safety, all adopted driven hanging basket to construct, but because insulation bracing ring is through tank skin external surface, construction volume is larger in the past, driven hanging basket only limits to the single-point construction of vertical direction, and the scope of operation is narrow, and job area is limited.As the welding of the insulation bracing ring of 10 ten thousand stere storage tanks must 2-4 portion driven hanging basket synchronous construction, equipment investment is required large, and personnel require manyly, have increased construction cost; Meanwhile, the running of driven hanging basket needs continued power, has a power failure or power-off once on-the-spot, will cause unnecessary construction trouble, not only people can be locked into high-altitude, and affect construction speed.
Summary of the invention
The purpose of this utility model is the weak point in order to overcome above-mentioned existing driven hanging basket construction, provide a kind of simple and reasonable, cost is low, simple operation, construction safety, can obviously improve the large-scale storage tank external surface construction trailer of construction quality and accelerating construction progress.
Large-scale storage tank external surface construction trailer of the present utility model, its structure comprises a shape hanger, bearing wheed, control wheel, dolly, tank skin wheel, described bearing wheed is contained in column lower end inside a shape hanger, control wheel and be contained in column lower inside inside a shape hanger, dolly is lifted on the outer heel post of a shape hanger, and tank skin wheel is contained on dolly inner side edge.
For the ease of construction, on above-mentioned dolly, be distributed with at least one deck workbench, dolly 4 sides are provided with cat ladder.
For the ease of automatic walking, can on door shape hanger, be provided with reducing motor, reducing motor is through belt and belt pulley or chain and chain wheel drive bearing wheed.
Large-scale storage tank external surface construction trailer of the present utility model, with crane, the bearing wheed of trailer is lifted on the wind girder bed board of tank deck and gets final product operation, mainly by 2, top bearing wheed along walking on wind girder bed board, control simultaneously wheel withstand channel-section steel inside groove make it easy to walking, tank ancient piece of jade, round, flat and with a hole in its centre difficulty in walking for preventing little traffic allowance, in bottom or/and middle part 2 trundles of each welding withstand dolly can be easily along the walking of a tank ancient piece of jade, round, flat and with a hole in its centre, and then guarantee the needs that workman constructs in the above.Have simple and reasonablely, cost is low, simple operation, the advantages such as construction safety.For constructor provides the construction space of a safety in high-altitude, in having improved construction quality, also improve execution conditions, owing to realizing the each high level of synchronization construction of tank skin, can be in improving safety factor, obviously accelerating construction progress.Be particularly suitable for large-scale storage tank external surface to be incubated bracing ring welding procedure, be also applicable to large-scale storage tank external surface to carry out anticorrosive construction and lay every constructions such as insulation layer.

tool present embodiment
referring to accompanying drawing, 1 in figure is a shape hanger, the 2nd, and bearing wheed, the 3rd, control wheel, the 4th, dolly, the 5th, workbench, 6 and 7 is tank skin wheels, the 8th, reducing motor, the 9th, belt or chain, the 10th, belt pulley or sprocket wheel, the 11st, tank deck channel-section steel, the 12nd, wind girder bed board, the 13rd, a tank ancient piece of jade, round, flat and with a hole in its centre.
Large-scale storage tank external surface construction trailer of the present utility model, its structure as shown in Figure 1, comprise a shape hanger 1, bearing wheed 2, control wheel 3, dolly 4, tank skin wheel 6 and 7, described bearing wheed 2 is contained in a shape hanger 1 inner side column lower end, control wheel 3 and be contained in a shape hanger 1 inner side column lower inside, dolly 4 is lifted on an outer heel post of shape hanger 1, and tank skin wheel 6 and 7 is contained on dolly 4 inner side edges.
For the ease of construction, on above-mentioned dolly 4, can be provided with as required multiple benches platform 5, for many people construct working platform is provided at differing heights simultaneously, for the ease of up and down, dolly 4 sides are provided with cat ladder.
For the ease of automatic walking, can on door shape hanger 1, be provided with reducing motor 8, reducing motor 8 is through belt 9 and belt pulley 10 or chain and chain wheel drive bearing wheed 2.Its structure as shown in Figure 2.
Large-scale storage tank external surface construction trailer of the present utility model, with crane, the bearing wheed of trailer is lifted on to tank deck 12 and gets final product operation, main 2, the top bearing wheed 2 that passes through is along walking on wind girder bed board 12, control simultaneously wheel 3 withstand tank deck channel-section steel 11 inside grooves make it easy to walking, a tank ancient piece of jade, round, flat and with a hole in its centre 13 difficulty in walking for preventing little traffic allowance, or/and respectively welding 2 tank skin wheels 7 and 6, middle part withstands dolly 4 in bottom, can easily walk along a tank ancient piece of jade, round, flat and with a hole in its centre 13, and then guaranteeing the needs that workman constructs in the above, its structure is as shown in Figure 3.When mobile, the force of sliding friction that only needs a people can overcome trailer and wind girder web at top promotes trailer and walks according to path, as below have again a complementary cooperation traction of people, can guarantee that trailer walks more smooth and easy.
As set up automatic travelling device at trailer top, increase a set of simple drive unit, as shown in Figure 2, can become the trailer of automatic walking, can be by the constructor on dolly according to construction speed, by button from main control trailer advance, retreat, the function such as brake, enable reducing under the prerequisite of labour intensity, further meet the service efficiency of the raising trailer of construction needs.
