Existing tipping lorry for building is divided into plain edition, multidigit discharging type, high-order discharging type and self-chambering type.Common tipping lorry, its work loading height and discharging are highly all immutable, can only topple over material toward ground towards the place ahead; Multidigit discharging type its work loading height of tipping lorry and discharging are highly also immutable, generally can topple over material toward ground towards left and right, first three orientation; High-order discharging type tipping lorry can change the discharging height, but its work loading height is immutable, particularly during hand charging, still wastes time and energy; Self-chambering type tipping lorry has solved the charging problem effectively, but because discharging is highly low, still only is suitable for toppling over material toward ground.

As fork truck, generally be used for short distance transportation in indoor, the factory.Because structure limits, behind the fork loading thing, weight is suspended from front part of vehicle, is balance front overhang weight, and complete vehicle quality is bigger, so in being not suitable for, grow distance and cross-country transportation.

In actual condition, because various material purposes are different, service condition also has difference, often requires existing certain discharging height, can improve charging efficiency again.For the goods that is suitable for pitching dress, should pitch dress, high-order discharging is in doing again, long distance and cross-country transportation.

The purpose of this utility model provides a kind of self-chambering height and unloads tipping bucket (fork) car, and it can place ground with hopper at when filling with substance, is used as scraper bowl, has the partly tipping lorry of self-chambering function.Simultaneously, shelve by the fork that changes the outfit, again can be as fork truck.During fork loading thing, goods is placed more than the vehicle frame, greatly alleviate than the deadweight of the general fork truck of equal carrying capacity, during again owing to transportation, goods is not to be suspended in the front, therefore, travel speed can improve relatively, and can finish relative high-order discharging and in, the cross-country transportation of long distance.

The utility model is realized as follows:

Hopper (2) is hinged by hinge pin (4) and carriage (1), and dump cylinder (3) one ends and carriage (1) are hinged, and the other end and hopper (2) are hinged; During dump cylinder (3) action, hopper (2) can rotate around hinge pin (4), to realize tumbling discharging.

Carriage (1) is hinged by swing arm (11), connecting rod (13) and rocker (12), rocking bar (9); Being hinged by carriage (1), swing arm (11), connecting rod (13), rocking bar (9) constitutes a parallel four-bar linkage, and when guaranteeing that carriage (1) drives hopper (2) lifting, hopper (2) can parallelly move.Elevating ram (14) one ends and swing arm (11) are hinged, and the other end and rocker (12) are hinged, and during elevating ram (14) action, swing arm (11) rotates around hinge pin (8), thereby makes carriage (1) together with the parallel lifting of hopper (2).

Rocker (12) is connected with vehicle frame (6) by hinge pin (7), and rocking bar (9) one ends and rocker (12) are hinged, and the other end and swing arm (11) are hinged, and pull bar (10) one ends and vehicle frame (6) are hinged, and the other end and rocking bar (9) are hinged.Rocker (12), rocking bar (9), pull bar (10), vehicle frame (6) are hinged and constitute a parallel four-bar linkage, to guarantee when rocker (12) rotates, rocking bar (9) can be parallel moves, thereby when guaranteeing that hopper (2) is in any position, can both keep level.The end and the vehicle frame (6) that play charge of oil cylinder (5) are hinged, and the other end and rocker (12) are hinged.When playing charge of oil cylinder (5) action, drive rocker (12) and rotate around hinge pin (7).

When hopper (2) need place ground, make elevating ram (14) action earlier, carriage (1) is lifted together with hopper (2) leave vehicle frame (6), made charge of oil cylinder (5) action then, during rocker (12) swing, carriage (1) can be positioned over ground together with hopper (2), make vehicle frame (6) not interfere phenomenon.After hopper (2) places ground, make dump cylinder (3) action, hopper (2) turns to around hinge pin (4) and is in the shovel holding position, can shovel dress to material.

Pitch when the utility model and to pretend when industry, dismounting hinge pin (15) and hinge pin (16) can be removed carriage (1), hopper (2), dump cylinder (3), again by hinge pin (15) and hinge pin (16) fork can be shelved (17) and swing arm (11) again, connecting rod (13) is hinged, then pallet fork (18) is hung on fork and shelves on (17), can pitch and pretend industry.When pallet fork (18) when placing ground, goods is pitched dress, during transportation, goods is placed on the vehicle frame (6).During unloading, can pallet fork be given rise to desired height, finish discharging according to different operating modes.
