The utility model discloses a kind of reinforcement type standard section of tower crane guard ring forming frock, including chassis, multiple bar shaped limited block it is welded with on described chassis, described limited block includes inner limited block and outer limited block, described inner limited block, outer limited block are all with the center a on chassis as the center of circle, being arranged on chassis with R1, R2 for radius circumferentially L1, L2 respectively, described inner limited block is the most corresponding with outer limited block, and forms an annular guard ring stopper slot between the two；Described inner limited block is provided with opening with circumference L1, L2 same place of outer limited block arrangement, and block, outer support block are shored in described opening both sides in being welded with, both are staggered.A kind of reinforcement type standard section of tower crane guard ring forming frock that this utility model provides, has made original square limited block into triangle, and its structure is more firm, and ruggedness is strong, and cost is low, and material consumption reduces by one times.
Description
Technical field
This utility model relates to the safe frock of standard section of tower crane, especially relates to a kind of reinforcement type standard section of tower crane guard ring forming frock.
Background technology
Tower crane is the main heavy construction machinery of construction site, because its lifting altitude is high, wide coverage, efficiency high and be widely used, and in work progress, staff needs upwards to climb to driver's cabin by cat ladder, now the guard ring around cat ladder just becomes particularly important, prevent workmen from safety problem occurring, at present, the guard ring manufacture that factory is used, forming frock, its simple in construction, and it is practical, but find in the course of the work, square limited block on chassis can work stress for a long time, limited block is caused to damage, even break, less stable.
Utility model content
The purpose of this utility model is to provide a kind of reinforcement type standard section of tower crane guard ring forming frock, overcomes the defect of prior art, has made original square limited block into triangle, the problem solving limited block in use poor stability.
In order to achieve the above object, this utility model have employed techniques below scheme:
A kind of reinforcement type standard section of tower crane guard ring forming frock, including the multiple limited blocks arranged on chassis, described limited block includes inner limited block and outer limited block, and described inner limited block, outer limited block all with the center a on chassis as the center of circle, are arranged on chassis with R1, R2 for radius circumferentially L1, L2 respectively.
Further improvement of the utility model scheme is, the facade of described inner limited block and outer limited block is right angled triangle, so makes that limited block is more firm, ruggedness strengthens；Described inner limited block is the most corresponding with outer limited block, and forms an annular guard ring stopper slot between the two.
Further improvement of the utility model scheme is, a right-angle side of described inner limited block and outer limited block is all by being fixedly welded on chassis, and another right-angle side is parallel to each other relatively.
Further improvement of the utility model scheme is, described inner limited block is arranged on circumference L1, L2 with outer limited block is the most equidistant.
Further improvement of the utility model scheme is, described inner limited block corresponding two-by-two and outer limited block are on same Radius.
Further improvement of the utility model scheme is, described circumference L1 radius R1 is less than L2 radius R2.
Further improvement of the utility model scheme is, described inner limited block is provided with opening with circumference L1, L2 same place of outer limited block arrangement, and block, outer support block are shored in described opening both sides in being welded with, both are staggered.
Compared with prior art, the beneficial effects of the utility model are:
One, a kind of reinforcement type standard section of tower crane guard ring forming frock that this utility model provides, forms an annular guard ring stopper slot, it is simple to guard ring forming between its most corresponding inner limited block and outer limited block；During iron plate is bent to guard ring, inside shore block play restriction iron plate further towards center a place bending, outer support block to iron plate end offer one bent support point, it is simple to by the brake forming of iron plate end.
Two, a kind of reinforcement type standard section of tower crane guard ring forming frock that this utility model provides, has made original square limited block into triangle, and its structure is more firm, and ruggedness is strong, and cost is low, and material consumption reduces by one times.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is structural side view of the present utility model.
Fig. 3 is Structure Comparison figure of the present utility model.
In figure, 1 is chassis, and 2 is interior limit body, and 3 is outer limit body, and 4 is guard ring stopper slot, and 5 is guard ring, and 6 is opening, 7 be in shore block, 8 is outer support block.
Detailed description of the invention
Below in conjunction with the accompanying drawings and detailed description of the invention, it is further elucidated with this utility model, it should be understood that following detailed description of the invention is merely to illustrate this utility model rather than limits scope of the present utility model, after having read this utility model, those skilled in the art all fall within the application claims limited range to the amendment of the various equivalent form of values of utility model.
Embodiment 1: a kind of reinforcement type standard section of tower crane guard ring forming frock as shown in Figures 1 and 2, including the multiple limited blocks arranged on chassis 1, described limited block includes inner limited block 2 and outer limited block 3, described inner limited block 2, outer limited block 3 are all with the center a on chassis 1 as the center of circle, it is arranged on chassis 1 with R1, R2 for radius circumferentially L1, L2 respectively, it is characterized in that: described inner limited block 2 is right angled triangle with the facade of outer limited block 3, described inner limited block 2 is the most corresponding with outer limited block 3, and forms an annular guard ring stopper slot 4 between the two；One right-angle side of described inner limited block 2 and outer limited block 3 is all by being fixedly welded on chassis 1, and another right-angle side is parallel to each other relatively；Described inner limited block 2 is arranged on circumference L1, L2 with outer limited block 3 is the most equidistant；Described inner limited block 2 corresponding two-by-two and outer limited block 3 are on same Radius；Described circumference L1 radius R1 is less than L2 radius R2；Described inner limited block 2 is provided with opening 6 with circumference L1, L2 same place of outer limited block 3 arrangement, and block 7, outer support block 8 are shored in being welded with in described opening 6 both sides, and both are staggered.
Utility model works mode is as follows: during work, first the bending of bar shaped iron plate is positioned in annular guard ring stopper slot 4, utilize inner limited block 2, outer limited block 3, it is limited in guard ring stopper slot 4, and is curved it molding, then utilize spanner to be bent iron plate end, in the process, inside shoring block 7 and play restriction iron plate further towards the bending of center a place, outer support block 8 gives the offer of iron plate end one bent support point, it is simple to by the brake forming of iron plate end.A kind of reinforcement type standard section of tower crane guard ring forming frock that this utility model provides, has made original square limited block into triangle, and its structure is more firm, and ruggedness is strong, and cost is low, and material consumption reduces by one times.
