Abstract
The utility model relates to a main frame body structure of a forklift outer gantry. The main frame body structure of the forklift outer gantry mainly comprises a left frame body, a right frame body, an upper cross beam and a lower cross beam, wherein a middle cross beam is arranged between the upper cross beam and the lower cross beam; the middle cross beam is respectively connected to the left frame body and the right frame body through side plates on two sides; rib plates are arranged on connection positions of the left frame body and the right frame body with the lower cross beam; and the right frame body is further provided with a slant hydraulic cylinder support. According to the main frame body structure of the forklift outer gantry, facts are found from practical use and experimental analysis that after loading is added under the same conditions, deformation of the main frame body structure is added slightly, but the deformation differs slightly, and the main frame body structure can be used in various working conditions. In addition, the cross beams of a composite structure in the main frame body are good in stress state, simple in structure, small in mass, optimized in processing techniques of components and parts, and high in production efficiency at the same time.
Description
Technical field
The utility model relates to a kind of fork lift truck structure, is specifically related to a kind of main frame structure of outer portal frame of forklift.
Background technology
Forklift door frame, when being forklift workability goods is carried out the execution unit of stacking, the outer mast main frame structure of using on the fork truck at present is mainly by left and right sides frame body, three laterally connect dull and stereotyped the composition, left and right sides frame body opening is relative, three cross connecting plates and left and right sides frame body joint are welded and fixed, processing technology is complicated, production procedure is longer, need simultaneously the mould manufacturing, productive costs is higher, because the door frame bearing capacity is large, so three plate welded seam built-up welding amounts are large, the built-up welding amount makes left and right sides frame body distortion greatly easily, the result of distortion makes it large with outer mast running-fit trueness error, and built-up welding operation element amount is large, for this reason, determines former common outer mast main frame structure is improved.
The utility model content
The utility model purpose is to provide a kind of intensity high in order to overcome the deficiencies in the prior art, and is not yielding during use, the main frame structure of the outer portal frame of forklift that stability and safety performance were high when load was heavy.
For achieving the above object, the technical solution adopted in the utility model is: a kind of main frame structure of outer portal frame of forklift, and the main frame structure of described outer mast mainly is comprised of left and right sides frame body, lower and upper cross-member, is provided with center member between the described upper and lower crossbeam; Described center member is connected on the frame body of the left and right sides by the both sides side plate; Described left and right sides frame body and cross sill joint are provided with gusset; Also be provided with the hydraulic tilt cylinder bearing on the described correct frame body.
Because the utilization of technique scheme, the utility model compared with prior art has following advantages:
The main frame structure of the outer portal frame of forklift of the utility model scheme, after use and experimental analysis, find, after under equal conditions loading, the utility model main frame structural distortion amount slightly increases, but deflection is more or less the same, can satisfy various operating modes uses, and the force-bearing situation of unitized construction crossbeam is better, simple in structure in the utility model main frame, and quality is less, optimized parts machining technique, production efficiency is higher simultaneously.
Description of drawings
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:
Accompanying drawing 1 is of the present utility model a kind of;
Wherein: 1, left frame body; 2, correct frame body; 3, entablatrance; 4, cross sill; 5, center member; 6, side plate; 7, gusset; 8, hydraulic tilt cylinder bearing.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
Accompanying drawing 1 is the main frame structure of a kind of outer portal frame of forklift described in the utility model, and the main frame structure of described outer mast mainly is comprised of left and right sides frame body (1,2), lower and upper cross-member (3,4), is provided with center member 5 between the described upper and lower crossbeam (3,4); Described center member 5 is connected on the left and right sides frame body (1,2) by both sides side plate 6; Described left and right sides frame body (1,2) is provided with gusset 7 with cross sill 4 joints; Also be provided with hydraulic tilt cylinder bearing 8 on the described correct frame body 2.
Below only be concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, all drop within the utility model rights protection scope.
