Abstract
The utility model discloses a safety protection structure of a mine dumper cab. The safety protection structure of the mine dumper cab comprises a cage type frame and a covering. The cage type frame comprises a top frame (1), a front frame (2), a rear frame (3), a side frame I (4) and a side frame II (5) which are respectively provided with a strengthening structure and mutually fixedly connected, wherein the strengthening structure (11) of the top frame (1) is in the grid shape, the side frame I (4) is provided with at least two supporting pillars (41) which support the top frame, and a space where a driver can come in and go out exists between every two adjacent supporting pillars. In the process of loading and unloading earth-rocks, damage to a driver caused by the falling of the earth-rocks is effectively avoided. When a vehicle overturn accident happens, large deformation of a cab is avoided, the driver is protected and property loss is lowered to the maximum extent. The safety protection structure of the mine dumper cab is large in integral rigidity, strong in adaptability, simple to manufacture, time-saving, labor-saving, and cost-saving. Due to the simple structure, the safety protection structure of the mine dumper cab is convenient to produce, low in cost and suitable for wide popularization.
Description
Technical field
The utility model relates to driving compartment, platform or the similar devices that international Patent classificating number E02F9/16 driver uses.
Background technology
Along with rising, the hydraulic engineering maximization of large outdoors colliery, iron ore, copper mining operation and output are built year by year and increased, little tonnage dumping car can't satisfy the demand of large surface mine transportation and construction of hydro project, quarry tipper is just towards the large-tonnage future development, and the user is also more and more higher to the requirement of the overall performance of quarry tipper and safety in operation, reliability aspect.Because road mostly is the metal road of interim laying during the quarry tipper transportation; road conditions and execution conditions are abominable; must guarantee the personal safety of chaufeur and reduce as much as possible property damage; this just requires cab of mine dump truck to possess Roll-Over Protective Structure and Falling object protective structure; and usually the two as a whole steel structure system, i.e. safety protection structure.
Summary of the invention
The utility model is for the proposition of above problem, and a kind of cab of mine dump truck safety protection structure of development has: cage modle framework and metal skin;
Described cage modle framework comprises: have separately the reinforcement structure, the top frame that is mutually permanently connected, forward frame, rear frame, side framework I and side framework II; The reinforcement structure of described top frame is latticed; Described side framework I has the pillar stiffener of at least 2 support, top frameworks, leaves the interval of freely coming in and going out for chaufeur between 2 adjacent pillar stiffeners.
Described side framework II has at least 2 pillar stiffeners, leaves the interval of freely coming in and going out for chaufeur between 2 adjacent pillar stiffeners.
Beam, the post of described top frame, forward frame, rear frame, side framework I and side framework II are the square-tube type steel, interfix by welding between described beam, the post.
The ruggedized construction of described forward frame is for being provided with reinforcing crossmember in the position on the lower side at described forward frame middle part.
Because a kind of cab of mine dump truck safety protection structure that has adopted technique scheme, the utility model to provide has been realized by a kind of simple structure, when the loading and unloading cubic metre of earth and stone, actv. has avoided falling cubic metre of earth and stone material to operator's compartment member's injury; When the accidents such as vehicle topples occur, avoid operator's compartment to cross the generation of large deformation, protect to greatest extent the chaufeur health and reduce property damage.This device integral rigidity is large, and strong adaptability is made simply, saves time, and is laborsaving, saves cost.Because it is simple in structure, not only be convenient to produce, and cost is very cheap is suitable for extensive popularization.
Description of drawings
Fig. 1 is the scheme drawing of the utility model cagelike structure
Fig. 2 is overall diagram of the present utility model
Among the figure: 1. top frame, 11. is strengthened structures, 2. forward frame, 21. reinforcing crossmembers, 3. rear frame, 4. side framework I, 41. pillar stiffener I, 5. side framework II, 51. pillar stiffener II.
The specific embodiment
Such as Fig. 1-shown in Figure 2: the utility model is mainly used in the large-scale mine load-carrying vehicle; load-carrying vehicle is when the loading and unloading cubic metre of earth and stone; as easy as rolling off a log generation falling rocks is dangerous; as a better embodiment; a kind of cab of mine dump truck safety protection structure has: cage modle framework and outside metal skin form an integral body, can actv. protection chaufeur and inner member.
In view of; most of falling rocks all is to fall from the top, as a better embodiment, is provided with reinforcement structure 11 in described top frame 1; described reinforcement structure is little latticed, and the size of grid can effectively be carried out the actv. protection to the operator's compartment member less than common falling rocks.
Consider the impulsive force that falling rocks falls and may rest on the operator's compartment top, operator's compartment is caused downforce, this just requires operator's compartment to have support on the good vertical direction, and preferred, described side framework I4 and side framework II5 have 2 pillar stiffeners separately.The performance of axle pressure is very excellent because the cylinder of cylinder structure bears, and preferred, described pillar stiffener is rectangular steel tube, can play good supporting role, can significantly not increase again the weight of framework simultaneously.Consider the convenience of chaufeur turnover, described 2 pillar stiffeners, between leave for the operator's compartment member, the spacing of freely coming in and going out after finishing whole framework, can arrange car door, further increases pressure resistance.
As a better embodiment, beam, the post of top frame 1, forward frame 2, rear frame 3, side framework I4 and side framework II5 are the square-tube type steel, and are interconnected and fixed by welding.
Covering very large draws from having in its plane, pressure and shearing strength value, and because the effect of rib is arranged, covering can unstability.Stressed-skin construction has than large bearing capacity and rigidity, and deadweight is very light.Preferably, the covering that the utility model adopts is metal skin, can the interior member of actv. protection operator's compartment.
Forwardly the middle part of framework 2 is provided with 2 reinforcing crossmembers 21, and forward frame 2 is divided into two large spaces, and upper space is used for installing windscreen, and lower space is used for arranging various controlling equipments.
The above; it only is the better specific embodiment of the utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to replacement or change according to the technical solution of the utility model and inventive concept thereof, as: adopt form, pillar stiffener form and the connection mode etc. of different reinforcement structures all should be encompassed within the protection domain of the present utility model.
