Embodiment

The technical solution of the utility model is described in detail below in conjunction with the accompanying drawings.

With reference to shown in Fig. 1, step of the present utility model, including main unit 1, mobile unit 2 and support unit 3.

Main unit 1 includes at least two layers platform with difference in height, in order to which operator stands in the flat of different height Job Operations are carried out to different height position on platform.With reference to shown in Fig. 1, the frame part of main unit 1 welded using angle steel and Into planar section is made of aluminum antiskid plate and is provided with three layers of platform, and respectively the first platform 11, second is flat from high to low The platform 13 of platform 12 and the 3rd, each layer of platform is square structure, and according to applying working condition, by the height between adjacent platforms Degree difference is arranged to 0.2 meter.

Mobile unit 2 is located at the lower section of main unit 1, for moving support to main unit 1.Wherein, it is preferred that Mobile unit 2 uses universal wheel, in order to carry out the flexible movement of all directions to main unit 1.It is further preferred that Four corner locations of the 3rd platform 13 are respectively equipped with a universal wheel in main unit 1, so as to ensure that main unit 1 is entered Row carries the stationarity of moving process.

Support unit 3 is located on two sides corresponding in main unit 1, and has Telescopic.Wherein, branch is worked as When support unit 3 is in stretching state, mobile unit 2 is placed in vacant state, now fixed branch of the main unit 1 in support unit 3 Under support, position immobilizes.When support unit 3 is in recovery state, mobile unit 2 directly contacts with ground, now main body Unit 1 can be moved freely flexibly under the mobile support of mobile unit 2.

In addition, in the utility model, on two sides of main unit 1, altogether provided with four support units 3, and And a support unit 3 is correspondingly arranged with a mobile unit 2.So, main unit 1 is carried out by four support units 3 Fixed support, it is ensured that the stability of support is fixed to main unit 1, is improved high by step of the present utility model progress Locate security during operation.

With reference to shown in Fig. 2 and Fig. 3, support unit 3 includes adjustable plate 31 and support bar 32.Adjustable plate 31 by bolt with Main unit 1 is fixedly connected, and guide groove 311 and stopper slot 312 are provided with adjustable plate 31, and wherein guide groove 311 is along perpendicular Nogata is to setting.Support bar 32 includes being mutually perpendicular to vertical bar 321 and the horizon bar 322 being fixedly connected, wherein vertical bar 321 Inside guide groove 311, and can freely it be slided up and down in guide groove 311 and around own axis, horizon bar 322 in stopper slot 312, carry for limiting the shift position of the in the vertical direction of vertical bar 321, and to vertical bar 321 For support force.

Preferably, stopper slot 312 uses Contraband shape structure, including a vertical section 3121 and two horizontal segments 3122.Its In, vertical section 3121 vertically be arranged in parallel with guide groove 311.Two horizontal segments 3122 are located at vertical section 3121 respectively Two ends, and connected with vertical section 3121.

So, when horizon bar 322 moves up and down in vertical section 3121, vertical bar 321 can be driven to be oriented to Moved up and down in groove 311, realize the stretching and recovery action of vertical bar 321.When horizon bar 322 is placed in into horizontal segment 3122 When interior, horizon bar 322 can not continue the movement of above-below direction under the restriction effect of horizontal segment 3122, and then limit vertically Bar 321 is in the position that vertical direction moves, while in horizontal segment 3122 under the supporting role of horizon bar 322, realizing horizon bar The support of 322 pairs of vertical bars 321, and then realize that support unit 3 supports to the fixed of main unit 1.

Wherein, when horizon bar 322 is located in the horizontal segment 3122 of the upper end of vertical section 3121, vertical bar 321 is relative to leading Recovery state is in groove 311, lower end and the ground of vertical bar 321 disengage.When horizon bar 322 is located under vertical section 3121 When in the horizontal segment 3122 at end, vertical bar 321 is in stretching state, lower end and the ground of vertical bar 321 relative to guide groove 311 Face contacts, and mobile unit 2 is placed in vacant state.

It is further preferred that adjustable plate 31 vertically on be provided with two stopper slots 312, meanwhile, in support bar 32 vertically on also be provided with two horizon bars 322, and the distance between two stopper slots 312 and two horizon bars The distance between 322 correspondent equals.So, carry out spacing to vertical bar 321 simultaneously by two horizon bars 322 and support is provided Power, stability when support unit 3 main unit 1 is fixed support can be improved.

Preferably, with reference to shown in Fig. 1, the direction of platform is climbed from low to high along main unit 1, positioned at top The anterior position of first platform 11 is provided with front apron 111, and side shield 112 is respectively equipped with its left and right two side position.So, When the first platform 11 carries out work high above the ground, stabilization when can ensure to stand by hand steered baffle plate, guarantee operated operator The safety of journey.

It is further preferred that step of the present utility model is additionally provided with the tool stand 4 for placing power tool temporarily.Work Tool platform 4 is square platy structure, the corner location between front apron 111 and side shield 112.Wherein, one of tool stand 4 By being rotatablely connected between hinge and side shield 112, another adjacent side is detachable with front apron 111 by linking up with for side Be fixedly connected.So, when needing to use tool stand 4, by around hinge turning tool platform 4 to horizontality, then by Tool stand 4 is fixedly connected by hook with front apron 111.When without using tool stand 4, hook is removed, and in the company of hinge Connect and tool stand 4 is gone into vertical state abutted on side shield 112 under effect.

In addition, with reference to shown in Fig. 1, two bracelets 5 are respectively equipped with the front side of main unit 1 and rear side.By bracelet 5 not Free pull can be only carried out to step to move, and when operation support unit 3 is stretched out or recovery acts, first By lifting bracelet 5, upward lifting is carried out to main unit 1, makes the lower end of mobile unit 2 or support bar 32 liftoff, then Again by being operated in stopper slot 312 to horizon bar 322, stretching or the reclaimer operation of support bar 32 are completed.
