Abstract
The invention discloses a straight ladder for a ship, comprising two side plates (1) which are mutually parallel and are vertically arranged, wherein a plurality of pedal supports which are mutually parallel are arranged between the two side plates (1). The straight ladder for a ship is characterized in that both sides of each side plate (1) are provided with inward first bent edges (3); the upper side and the lower side of the pedal supports (2) are provided with second bent edges (4); and the side plates (1) are connected with installation plates (6). Compared with the prior art, the invention has the advantages of light weight, convenient machining, easy movement, no need of on-site machining, time and labor saving, low working intensity, and the like.
Description
Technical field
The present invention relates to a kind of ladder, particularly a kind of straight ladder for ship is mainly used on all kinds of boats and ships or in shipbuilding process and uses.
Background technology
Need to use a large amount of vertical ladders in the shipbuilding process or on all kinds of boats and ships, the structure of existing vertical ladder is that two side plates that be parallel to each other and that vertically be provided with are arranged, the foot-operated support that is parallel to each other is arranged between biside plate, side plate and foot-operated support mostly are channel-section steel section bar welding production, during use side plate is fixed on the somewhere by connecting element, makes side plate be in vertical state.The vertical ladder of this structure is from great, is difficult for moving, and major part is a welding processing at the scene, and site environment is impacted, and wastes time and energy, and labour intensity is big.
Summary of the invention
The purpose of this invention is to provide a kind of in light weight, easy to process, easily move, need not field machining, time saving and energy saving, operation intensity straight ladder for ship, overcome the deficiencies in the prior art
Straight ladder for ship of the present invention, comprise two side plates that be parallel to each other and that vertically be provided with, be provided with a plurality of foot-operated support that is parallel to each other between two side plates, there is the first inside crimp on the both sides of side plate, there is second crimp on the both sides up and down of foot-operated support, and side plate is connected with adapter plate.
Straight ladder for ship of the present invention, second crimp in the wherein said foot-operated support are crooked to the inside, and in the middle part of foot-operated support the reinforced rib of projection are laterally arranged.
Straight ladder for ship of the present invention, bending part following in the wherein said foot-operated support is arranged porose.
Straight ladder for ship of the present invention, compared with prior art have in light weight, easy to process, easily move, need not field machining, time saving and energy saving, advantage such as operation intensity is little.
Description of drawings
Fig. 1 is the structural representation of the specific embodiment of the invention;
Fig. 2 is an A-A sectional schematic diagram shown in Figure 1;
Fig. 3 is a B-B sectional schematic diagram shown in Figure 1;
Fig. 4 is a C-C sectional schematic diagram shown in Figure 1.
The specific embodiment
Shown in Fig. 1,2,3,4: 1 is two side plates that are parallel to each other and vertically are provided with, and 2 for being connected the foot-operated support that is parallel to each other between the biside plate.The both sides of side plate 1 have inside and first crimp 3 symmetry.The bottom and upper segment of foot-operated support 2 all has second crimp, 4, the second crimps 4 crooked to the inside and symmetrical up and down, and in the middle part of foot-operated support 2 reinforced rib 8 of projection is laterally arranged.Following bending part arranges porose 5 in foot-operated support 2.The upper inner of side plate 1 has cushion block 7, there is adapter plate 6 in the outside, by bolt cushion block 7, side plate 1, adapter plate 6 fixedly is connected as a single entity, and another termination of adapter plate 6 is fixedly connected on the basis, side, the bottom of side plate 1 is supported on the horizontal basic plane, guarantees that side plate 1 vertically is provided with.
Above-mentioned side plate 1, foot-operated support 2 be sheet metal through processes moulding such as shearing, punching press, roll extrusion, and side plate 1, foot-operated support 2 be structure as a whole, and foot-operatedly supports that rounding off is connected between 2 two ends and the side plate 1.
Claims (3)
1. straight ladder for ship, comprise two side plates (1) that be parallel to each other and that vertically be provided with, between two side plates (1), be provided with a plurality of foot-operated support (2) that is parallel to each other, it is characterized in that: there is inside first crimp (3) on the both sides of side plate (1), there is second crimp (4) on the both sides up and down of foot-operated support (2), and side plate (1) is connected with adapter plate (6).
