Abstract
The utility model relates to a main-subsidiary integration autocrane frame which is formed by cross beams and longitudinal beams, wherein the number of the longitudinal beams is two, the longitudinal beams are beams of variable cross-section, and the cross-sectional area of the middle ends and the rear ends of the longitudinal beams is larger than that of the front ends of the longitudinal beams; the number of the cross beams is at least four, a rotary supporting ring is arranged on the rear portion of the frame, the supporting ring is connected with an upper airfoil of the frame, a breadth face of the frame and the cross beams of the frame, and the longitudinal beams are connected with a support in a riveting mode through rivets. According to the main-subsidiary integration autocrane frame, center of gravity of the frame is lowered, coincident load carrying of the center of gravity of the frame and the center of gravity of a lifting part, deformation of the frame is small, safety coefficient is high, service life is long, welding on the frame is not needed, the frame is prevented from being bent, refitting period is shortened, and mass production is facilitated.
Description
Technical field
The utility model relates to a kind of vehicle frame that is installed on the transport vehicle chassis, specifically, relates to a kind of major-minor all-in-one car crane frame.
Background technology
Elevator machinery refers to that its scope dictates is the elevator that rated load weight is greater than or equal to 0.5t for the electromechanical appliance of vertical lift or vertical lift and parallel motion weight; Rated load weight is greater than or equal to 1t, and hoisting depth is greater than or equal to the fixing electric block of the hoisting crane of 2m and load-bearing form etc.Usually elevator machinery is by lifting mechanism (making the article up-and-down movement), operating unit (elevator machinery is moved), luffing mechanism and swing type mechanism (making article make parallel motion), add metallic magnetism, engine installation is handled control and necessary auxiliary device combines.
The common position of hoisting crane is relatively fixing, perhaps as far as possible mobile among a small circle, be applicable to factory building and workshop and use, and still for loading-unload machine equipment or the heavy parts in interim place, fixed crane has just highlighted the inadequate natural endowment of himself; Therefore existing car hosit has widely market.
But existing car hosit is the lifting part that installs additional on the general two class chassis that car production producer provides with subframe, and the repacking cycle is long, and very easily causes vehicle frame crooked.
The utility model content
For above-mentioned deficiency of the prior art, it is a kind of simple in structure that the utility model provides, and frame mass centre reduces, the major-minor all-in-one car crane frame that frame mass centre is large with the bearing load that the center of gravity of lifting part overlaps.
Technical solution adopted in the utility model is:
A kind of major-minor all-in-one car crane frame is comprised of crossbeam and longeron, and described longeron is two, and described longeron is beam with variable cross-section.
In the described longeron, the sectional area of rear end is greater than the sectional area of the front end of longeron.
Described crossbeam is at least 4.
Described vehicle frame rear portion is provided with the rotary support ring, and support ring is connected with top airfoil, breadth and the crossbeam of vehicle frame.
Described in length and breadth beam and support connect the employing rivet.
The beneficial effect of the relative prior art of the utility model:
The utility model major-minor all-in-one car crane frame, frame mass centre reduces, frame mass centre is large with the bearing load that the center of gravity of lifting part overlaps, the vehicle frame distortion is little, and safety factor is high, long service life, need not to weld at vehicle frame, avoid vehicle frame crooked, also shorten the repacking cycle, be convenient to mass production.

The specific embodiment
Referring to drawings and Examples the utility model is described in detail:
Accompanying drawing 1 to 3 as can be known, a kind of major-minor all-in-one car crane frame is comprised of crossbeam and longeron, described longeron is two, described longeron is beam with variable cross-section; In the described longeron, the sectional area of rear end is greater than the sectional area of the front end of longeron; Described crossbeam is at least 4; Described vehicle frame rear portion is provided with rotary support ring 10, and support ring 10 is connected with top airfoil, breadth and the crossbeam of vehicle frame.Described in length and breadth beam and support connect the employing rivet.
Chassis side rail adopts variable section structure in Fig. 1, and the narrow breadth in left side is installed the automobile typical component such as driving engine, vehicle body, propons.The wide breadth in right side is done the car hosit bearing part, and car hosit rotating part support ring is installed on top, and the automobile crane supporting leg case is installed in the bottom.Because support ring and the supporting leg case part of standards of different car hosit manufacturer are not same, so support ring and supporting leg case partly adopt removably, are convenient to change support ring and the supporting leg case of each model.
Shown in Fig. 2, this all-in-one car crane frame is comprised of two longerons and multiple tracks crossbeam and various car accessories mounting bracket, beam and support connect the employing rivet in length and breadth, and the supporting leg case is connected high strength bolt to connect with car hosit rotating part support ring.
Shown in Fig. 3, all there is connecting bore the junction of the top airfoil of car hosit support ring and vehicle frame, breadth and crossbeam, guarantees that support ring is fixing reliable.
The car hosit body frame partly adopts WL700 vehicle frame special-purpose board compressing, the car hosit rotating part adopts special stand to be connected with vehicle frame, supporting leg case and annex all adopt high strength bolt to connect, arrange vehicle frame back axle mount pad according to the focus point of lifting part, front end becomes to cut partly installs the annexes such as driving engine, vehicle body, propons.
Vehicle Frame Design center of gravity of the present utility model overlaps with lifting part center of gravity, and bulk strength is better than installing additional on the automobile chassis frame of the former employing of car hosit enterprise the split-type structural of lifting part subframe, and complete vehicle weight alleviates 20%, is better than the welded type vehicle frame.
