Description
Technical field
This utility model relates to a kind of refrigerator car and stretches stair.
Background technology
At present, in goods transportation, generally require use, to refrigerator car, goods is carried out heat insulation transportation, and need to use the stair of linking when refrigerator car is unloaded, stair are directly placed upside down in doorway, compartment by traditional stair when practice, operate for shipping workman, but the stair being the most directly placed upside down in car door are the most firm, when shipping master worker tramples, often occur rocking, especially stair do not have strong construction at the contact jaw on doorway, compartment, so stair easily tilt, to shipping workpeople with potential safety hazard, the most traditional stair are not provided with pedal structure, shipping workman astasia when trampling, poor stability to master workers with potential safety hazard.
Utility model content
This utility model is in order to solve the above-mentioned deficiency of prior art, it is proposed that a kind of refrigerator car stretches stair.
In order to solve above-mentioned technical problem, this utility model is by the following technical solutions: a kind of refrigerator car stretches stair, including fixing stair frame, the both sides of described fixing stair frame have a pair cleat stanchion, the inner side of two cleat stanchions is hinged with one group of stair tread along the arrangement of cleat stanchion length direction, the both sides of the outboard end of described stair tread are hinged with a contraction stair frame, and this contraction stair frame has a pair coupling and is articulated with the limit cleat stanchion on stair tread both sides；The top of described fixing stair frame is provided with one for the bridging arrangement being connected refrigerator car, described bridging arrangement includes the supporting plate being arranged on the fixing stair frame back side, the inner transverse of described supporting plate runs through and is provided with a rotating shaft, the two ends of described rotating shaft are provided with a U-shaped overlap joint cushion block, described overlap joint cushion block stretches out towards the back side of supporting plate, and the bottom of this overlap joint cushion block is provided with the Magnet matrix for preventing fixing stair frame from sliding, the top of described supporting plate is additionally provided with one piece of baffle plate, described baffle plate correspondence is placed in the top of described overlap joint cushion block, between described overlap joint cushion block and baffle plate, bumper and absorbing shock spring is installed.
Compared with prior art, this utility model adds a contraction stair frame on traditional stair frame, shrink and be provided with stair tread on stair frame, the standing surface of stair tread is big, master workers are good stability when goods carrying is trampled, the foot section solving tradition stair frame tramples the problem that face is little, the most traditional stair frame directly bears against on refrigerator car in use, and this utility model have employed a bridging arrangement between stair frame and refrigerator car, bridging arrangement can help whole stair frame firmly to adsorb on refrigerator car, when preventing master worker to trample stair frame there will be rock crank-sided problem occur, completely eliminate potential safety hazard.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the partial enlarged drawing at A-A of the present utility model.
Detailed description of the invention
With embodiment, utility model is described in detail below in conjunction with the accompanying drawings.
As illustrated in fig. 1 and 2, the refrigerator car that the utility model proposes stretches stair, including fixing stair frame 1, the both sides of fixing stair frame 1 have a pair cleat stanchion 2, the inner side of two cleat stanchions 2 is hinged with one group of stair tread 3 along the arrangement of cleat stanchion length direction, the both sides of the outboard end of stair tread 3 are hinged with a contraction stair frame 4, and this contraction stair frame 4 has a pair coupling and is articulated with the limit cleat stanchion 5 on stair tread 3 both sides.
The top of fixing stair frame 1 is provided with one for the bridging arrangement being connected refrigerator car, bridging arrangement includes the supporting plate 6 being arranged on fixing stair frame 1 back side, the inner transverse of supporting plate 6 runs through and is provided with a rotating shaft 7, the two ends of rotating shaft 7 are provided with a U-shaped overlap joint cushion block 8, overlap joint cushion block 8 stretches out towards the back side of supporting plate 6, and the bottom of this overlap joint cushion block 8 is provided with the Magnet matrix 9 for preventing fixing stair frame from sliding, the top of supporting plate 6 is additionally provided with one piece of baffle plate 10, baffle plate 10 correspondence is placed in the top of described overlap joint cushion block 8, between overlap joint cushion block 8 and baffle plate 10, bumper and absorbing shock spring 11 is installed.
In this utility model, fixing stair frame 1 leans against on the following car mouth of refrigerator car, due to the captivation of Magnet matrix 9 obliquely so that whole fixing stair frame 1 is fixing to be attached on refrigerator car.
Additionally, this utility model adds a contraction stair frame on traditional stair frame, shrink and be provided with stair tread on stair frame, the standing surface of stair tread is big, master workers are good stability when goods carrying is trampled, the foot section solving tradition stair frame tramples the problem that face is little, the most traditional stair frame directly bears against on refrigerator car in use, and this utility model have employed a bridging arrangement between stair frame and refrigerator car, bridging arrangement can help whole stair frame firmly to adsorb on refrigerator car, when preventing master worker to trample stair frame there will be rock crank-sided problem occur.Completely eliminate potential safety hazard.
Above-described embodiment only have expressed several embodiments of the present utility model, and it describes more concrete and detailed, but can not be therefore understands that be the restriction to this utility model the scope of the claims.It should be pointed out that, for the person of ordinary skill of the art, without departing from the concept of the premise utility, it is also possible to make some deformation and improvement, these broadly fall into protection domain of the present utility model.Therefore, this utility model patent and protection domain should be as the criterion with appended claims.
