Abstract
The invention discloses a hydraulic stair assembly for a mining dump truck. The hydraulic stair assembly comprises a stair frame mounted on a main body and is characterized in that the stair frame is adjustably mounted on the main body through a retractable mechanism, and the retractable mechanism can control the stair frame to be opened, so that a driver get on or off the truck conveniently, the stair frame can be controlled to be retracted, and interference with traveling is avoided; guardrails allowing the driver to grab are further mounted on the stair frame. The assembly has the beneficial effects as follows: starting and stopping actions of the stair assembly are controlled by an electrical system, the angle is controlled electrically, a telescopic oil cylinder is pushed by hydraulic oil, locking is realized through simultaneous action of hydraulic system pressure maintaining and electric mechanical locking, the safety is high, and the driver can get on or off the truck very conveniently.
Description
Technical field
The invention belongs to mining machinery technical field, be specifically related to a kind of hydraulic pressure stair assembly for quarry tipper.
Background technology
Electric transmission dumper is one of equipment of important key in surface mine exploitation and extensive earthworks, wherein large-tonnage ore deposit card is the professional equipment for Ore or earthwork transportation, has the features such as load-carrying is big, length of run is short, work efficiency is high, specific energy consumption (t km) is low.Ore deposit card is widely used in the cubic metre of earth and stone transport of several big industries such as metallurgy, non-ferrous metal, chemical industry, coal, building materials, continuous expansion along with domestic and international large surface mine scale, produce the medium-sized mine of 500～1000 tons, many use loading capacity 100～the vehicle of 190 tons per year；The large-scale mine of more than 10000000 tons then uses the vehicle of more than 200～300 tons.
Driver gets on or off the bus every time and must use special stair, and this just requires that stair must be conveniently, safely.Common fixed stair terrain clearance is higher, and driver gets on or off the bus and need to pay special attention to, and security incident the most easily occurs；And due to stationary structure, result in being increased by area when vehicle travels, not only can hinder the normal pass under the conditions of some but also personnel outer to car may cause personal injury.
Summary of the invention
It is an object of the invention to overcome deficiency of the prior art, it is provided that a kind of hydraulic pressure stair assembly for quarry tipper, it is possible to freedom retractable meets the needs that driver gets on or off the bus.
For solving prior art problem, the invention discloses a kind of hydraulic pressure stair assembly for quarry tipper, including the ladder being arranged in main body, ladder is adjustably mounted in main body by jack, and jack can control ladder and open so that driver gets on or off the bus, also is able to control ladder and packs up to avoid to hinder and travel；The guardrail grasped for driver it is also equipped with on ladder.
Preferably, jack includes mounting seat, first connecting rod, second connecting rod and hydraulic cylinder；Mounting seat is arranged in main body, and the upper end thereof of ladder is arranged in mounting seat；The upper end thereof of first connecting rod is arranged in mounting seat, the hinged upper end being installed on hydraulic cylinder, its lower end；The lower end of second connecting rod is hingedly mounted on ladder, the most hinged upper end being installed on hydraulic cylinder, its lower end；The lower end of hydraulic cylinder is hinged to be installed on ladder.
Preferably, the inward facing surface of ladder is also equipped with a hinged-support, the lower end of hydraulic cylinder and the hinged installation of this hinged-support.
Preferably, mounting seat is also equipped with a pair cushion, can contact with this cushion when ladder is opened and realize damping.
Preferably, mounting seat offers installing hole, installing hole is equipped with bolt, between head and the installing hole of bolt, be additionally provided with packing ring.
The invention have the benefit that this building body assembly starts and electrical system control is passed through in stopping action, Angle ambiguity is also by electrical control, telescopic oil cylinder is promoted by hydraulic oil, locking is worked by hydraulic system pressurize and motor machine locking simultaneously, safety is high, significantly facilitates driver and gets on or off the bus.

Fig. 2 is the structural perspective below the present invention.
Reference:
1 mounting seat；2 ladders；3 bearing pins；4 baffle plates；5 packing rings；6 bolts；7 cushions；8 first connecting rods；9 second connecting rods；10 cylinder bodies；11 piston rods；12 hinged-supports.
Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings.Following example are only used for clearly illustrating technical scheme, and can not limit the scope of the invention with this.
As illustrated in fig. 1 and 2, a kind of hydraulic pressure stair assembly for quarry tipper, including the ladder 2 being arranged in main body, ladder 2 is adjustably mounted in main body by jack, and jack can control ladder 2 and open so that driver gets on or off the bus, also is able to control ladder 2 and packs up to avoid to hinder and travel；The guardrail grasped for driver it is also equipped with on ladder 2.
Jack includes mounting seat 1, first connecting rod 8, second connecting rod 9 and hydraulic cylinder.Offering installing hole in mounting seat 1, be equipped with bolt 6 in installing hole, be additionally provided with packing ring 5 between head and the installing hole of bolt 6, mounting seat 1 is arranged in main body by bolt 6.
The upper end of ladder 2 is hingedly mounted in mounting seat 1 by bearing pin 3, and the end of bearing pin 3 is further opened with through hole for installing plate washer 4, and plate washer 4 fits in and prevents ladder 2 from departing from mounting seat 1 in mounting seat 1.
The upper end thereof of first connecting rod 8 is arranged in mounting seat 1, the hinged upper end being installed on hydraulic cylinder, its lower end；The lower end of second connecting rod 9 is hingedly mounted on ladder 2, the most hinged upper end being installed on hydraulic cylinder, its lower end；The inward facing surface of ladder 2 is also equipped with a hinged-support 12, the lower end of hydraulic cylinder and this hinged installation of hinged-support 12.
It is also equipped with a pair cushion 7 in mounting seat 1, can contact with this cushion 7 when ladder 2 is opened and realize damping.
During hydraulic cylinder formal dress, its upper end is the head of piston rod 11, and its lower end is the afterbody of cylinder body 10.During hydraulic cylinder upside-down mounting, its upper end is the afterbody of cylinder body 10, and its lower end is the head of piston rod 11.In the present invention, determine that hydraulic cylinder is formal dress or upside-down mounting according to actual needs.
During the work of this hydraulic pressure stair assembly, declining oil inlet pipe oil-feed and produce pressure, first connecting rod 8 promotes second connecting rod 9, then linkage cylinder body 10 and piston rod 11, and such ladder 2 is opened, and facilitates driver to get on or off the bus.When hydraulic pressure stair assembly is packed up, by automatically controlled order, allowing lifting oil inlet pipe oil-feed produce pressure, ladder 2 sets back, and hydraulic pressure stair assembly safe lock is realized by the pressurize of hydraulic system.
