Detailed description of the invention
The embodiment of the present application, by providing a kind of lorry staircase and having the lorry of staircase, improves the staircase be made up of round steel in prior art and easily occurs distortion, bring the technical problem of potential safety hazard to the use of operating personnel.
Technical scheme in the embodiment of the present application is for solving the problems of the technologies described above, and general thought is as follows:
By the cross section of the column of described staircase and described pedal is all set to trench structure, because described trench structure has better rigidity for round steel, not easily produce distortion, therefore, staircase is made to have better rigidity, and not easily produce distortion, improve the staircase be made up of round steel in prior art and easily occur distortion, bring the technical problem of potential safety hazard to the use of operating personnel.
In order to better understand technique scheme, below in conjunction with Figure of description and concrete embodiment, technique scheme is described in detail.
Embodiment one
Easily occur distortion to improve the staircase be made up of round steel in prior art, bring the technical problem of potential safety hazard to the use of operating personnel, the application provides a kind of lorry staircase.Fig. 1 is the stereogram of the application one better embodiment lorry staircase.As shown in Figure 1, described staircase comprises two columns 10 and multiple pedal 20.
Described two columns 10 can be arranged in parallel, also can have certain angle.The cross section of described two columns 10 is trench structure, and the groove 11 on described two columns 10 is oppositely arranged.The column of described trench structure has better rigidity relative to the column that round steel is made, and not easily produces distortion.In the present embodiment, described trench structure is specially U-shaped.
Described multiple pedal 20 interval is arranged, and the number of described pedal 20 can be arranged as required.Distance between two pedals 20 adjacent in described multiple pedal 20 and the interval between two other pedal 20 can be equal, also can be unequal.The length of described multiple pedal 20 can be equal, also can not think, specifically can arrange according to the distance between described two columns 10.In the present embodiment, the interval of described multiple pedal 20 is equal, and length is equal.
The cross section of each pedal 20 in described multiple pedal 20 is also trench structure, and the two ends of described pedal 20 are arranged in the groove 11 of described two columns 10 respectively, and are fixed on described column 10.The pedal of described trench structure has better rigidity relative to the pedal that round steel is made, and not easily produces distortion.In the present embodiment, described trench structure is specially U-shaped.
In the present embodiment, described pedal 20 is fixed on described column 10 by pulling rivet.The groove 21 of described multiple pedal 20 is towards the same side, and in the present embodiment, the groove 21 of described pedal 20 is towards downwards.Described pedal 20 also comprises the bearing surface 22 for carrying operating personnel, in order to anti-skidding, described bearing surface 22 is provided with anti-skid structure 23, in the present embodiment, described anti-skid structure 23 is specially and is opened in groove on bearing surface 22 or projection, in other embodiments, described anti-skid structure can for being arranged at the slipmat etc. on bearing surface 22.
In addition, in the present embodiment, in order to alleviate the deadweight of described staircase, described two columns 10 and described pedal 20 are made by aluminum alloy materials.And described two columns 10 and described pedal 20 are stamping forming profile structure, increase the rigidity of staircase further.
By the column 10 of described staircase and the cross section of described pedal 20 are all set to trench structure, because described trench structure has better rigidity for round steel, not easily produce distortion, therefore, staircase is made to have better rigidity, and not easily produce distortion, improve the staircase be made up of round steel in prior art and easily occur distortion, bring the technical problem of potential safety hazard to the use of operating personnel.
By being fixed on described column 10 by pulling rivet by described pedal 20, the connection between described column 10 and described pedal 20 can be leaned on, and more attractive in appearance.
By arranging anti-skid structure 23 on the bearing surface 22 of described pedal 20, with when operating personnel use, safer, ensure the use safety of operating personnel.
With described pedal 20 and described column 10 being set to be made up of aluminum alloy materials, thus significantly reducing the deadweight of staircase, being beneficial to the light-weight design of vehicle.
Embodiment two
Based on the design of same utility model, the application also provides a kind of lorry with staircase, and described lorry comprises car body and lorry staircase, and described lorry staircase is identical with the 26S Proteasome Structure and Function of the staircase in embodiment one, is not repeating at this.Described lorry staircase is fixed on described car body.Described lorry staircase and described car body adopt riveted joint to complete to locate to be assembled.
By the column 10 of described staircase and the cross section of described pedal 20 are all set to trench structure, because described trench structure has better rigidity for round steel, not easily produce distortion, therefore, staircase is made to have better rigidity, and not easily produce distortion, improve the staircase be made up of round steel in prior art and easily occur distortion, bring the technical problem of potential safety hazard to the use of operating personnel.
By being fixed on described column 10 by pulling rivet by described pedal 20, the connection between described column 10 and described pedal 20 can be leaned on, and more attractive in appearance.
By arranging anti-skid structure 23 on the bearing surface 22 of described pedal 20, with when operating personnel use, safer, ensure the use safety of operating personnel.
With described pedal 20 and described column 10 being set to be made up of aluminum alloy materials, thus significantly reducing the deadweight of staircase, being beneficial to the light-weight design of vehicle.
