The specific embodiment
Embodiment to the utility model is elaborated below in conjunction with accompanying drawing, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
As the first aspect of the utility model, a kind of platform of tower machine is provided.Like Fig. 3 and shown in Figure 4, this platform comprises: supporting layer 110, first 130 and second 140.Supporting layer 110 is provided with the opening that extends along left and right directions, and opening comprises first opening and second opening.Be installed in first opening part for first 130; Be installed in second opening part for second 140.Preferably, the edge of first opening and second opening is provided with reinforcement 150 (for example angle bar etc.), through reinforcement 150 is set, has increased the intensity of first opening and second opening, has improved safety.Preferably, supporting layer 110 is expanded metal laths etc.Preferably, first 130 and second 140 are provided with expanded metal lath 170.Preferably, in the zone that is centered close to the opening place of supporting layer 110; First opening is positioned at the left side at center, and second opening is positioned at the right side at center.
In one embodiment, opening is a continuous integral body, and first opening and second opening are two zoness of different that belong to this opening.At another embodiment, opening is an integral body, and the center is provided with separating part, and this separating part is separated into first opening and second opening with this opening.In another preferred embodiment, platform also comprises beam 120, and supporting layer 110 is supported on the beam 120, and beam 120 is divided into said first opening and said second opening with opening.Especially, the relative beam 120 with second opening of said first opening is provided with symmetrically, and beam 120 is through the flat-bed center.
Please refer to Fig. 5 and Fig. 6.The cat ladder 500 of adjacent two standard knots 400 shown in Figure 5 is separately positioned on relative both sides, and the cat ladder 500 of adjacent two standard knots 400 shown in Figure 6 also is separately positioned on relative both sides.Suppose with Fig. 5 in the corresponding door in cat ladder position be second 140, with the corresponding door in the cat ladder position among Fig. 6 be first 130.When no matter the staff arrives the platform below in the utility model by Fig. 5 or cat ladder shown in Figure 6 so, can arrival corresponding second or first 's below with the position of the middle cat ladder of Fig. 5 or Fig. 6.Further, can open corresponding second or first, thereby arrive the platform top through corresponding second opening or first opening.
Like this, when the platform in use the utility model, just can adopt the cat ladder that is crisscross arranged.When cat ladder was crisscross arranged, the end of each standard knot was provided with transition platform, so that the staff is in the process of cat ladder, was arrived the cat ladder of second side of top standard knot through this transition platform by the cat ladder of first side of below standard knot.So even the staff falls in the process of climbing tower, the height of the standard knots that also can fall at most only will be blocked by the transition platform of standard knot, thus the safety factor when having improved staff's climbing tower.In addition, when the increase and decrease standard knot, the joint number that increases and decreases is also no longer included restriction,, all have corresponding first or second can use because no matter which side cat ladder is positioned at.At last,, therefore can be connected, strengthen cat ladder flat-bed commonality with polytype standard knot owing to adopted the platform in the utility model.
Preferably, the edge that is provided with 133, the second 140 of first clinchs that match with first opening, first 130 edge is provided with second clinch 143 that matches with second opening.With first 130 be example, when at closing time, just can take on the edge of first opening for first 130 through its first clinch 133, like this, when the staff climbs up platform, just may stand on supporting layer 110 or second 140.
Preferably, first 130 and/or second 140 are connected with supporting layer 110 pivotly.Certainly; First 130 and/or second 140 also can be alternate manner and supporting layer 110 bonded assemblys, for example, can be connected with supporting layer 110 through the mode of sliding; Promote first 130 or second 140 through horizontal direction, just can realize the function of opening the door or closing the door.
In a preferred embodiment, first 130 and/or second 140 is double doors.As shown in Figure 3, first 130 comprises that first door leaf 131 and 132, the second 140 of second door leafs comprise the 3rd door leaf 141 and the 4th door leaf 142.Therefore, the width of first door leaf 131 and second door leaf 132 is merely first 130 integral width half the, like this, can in less space, avoid and the interference of gusset on every side, so that first door leaf 131 and second door leaf 132 are pivoted to level attitude.So, can save hook, simplify the structure, use safe and convenient.
In a preferred embodiment; As shown in Figure 4; Beam 120 comprises first beam 121 and second beam 122, and platform comprises that also an end of cylinder 160, the first beams 121 of vertical placement is connected with an end of second beam 122 through cylinder 160; Cylinder 160 is positioned at the flat-bed center, so that cable passes in cylinder 160.Because cylinder 160 is arranged on the position of flat-bed center of gyration, therefore, in the rotating process of tower machine, can not damage cable, has improved the safety and the reliability of equipment.
As the second aspect of the utility model, a kind of undersetting of tower machine is provided, comprise lower cover and platform, this platform is above-mentioned platform, flat-bed supporting layer 110 is connected with lower cover 200 respectively with beam 120.
As the third aspect of the utility model, a kind of tower machine is provided, comprise undersetting, this undersetting is above-mentioned undersetting.Preferably, the tower machine also comprises a plurality of standard knots, and a plurality of standard knots connect the back successively and are connected with undersetting, and the cat ladder of a plurality of standard knots is provided with on left and right directions alternately.
The preferred embodiment that the above is merely the utility model is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
