Abstract

The utility model relates to a novel wheel-typed well service truck which is composed of a chassis, an engine, a passenger-car-typed cab, a drifting device, a hydraulic system, an air control brake device and other parts, wherein, the chassis belongs to the modification of the chassis part of the cross-country lorry of Dongfanghong-665 model; an 8120F model air-cooled diesel engine is adopted; the running and drifting operations of the truck share one gearbox: a dynamic path is assigned to a drive axle for running, and the other path is transferred to the drifting device for working. Running states are divided into four sorts: foot brake, hand brake, emergency brake and exhaust brake; drifting states are divided into three sorts: hand brake, air brake and mechanical brake. The well service truck has reasonable design and reliable use.

Description

Wheel type truck

The utility model is a kind of oil well repairing operation machinery.

At present, operation major parts such as the oil well in oil field is installed, debugs, cleared up, maintenance and equipment carrying are utilized the crawler type tractor hoist of the tractor or the bulldozer transformation of the way, to destroy the road surface during walking, otherwise pave with steel plate, perhaps utilize the iant flat truck haul, this not only results in hand cramps to the oil field, the cost substantial contribution, and carrying and dragging among the worker and may have an accident, bring unnecessary loss for people and life.

But the purpose of this utility model is to develop a kind of oil well implement a tractor serves several purposes, and a kind of novel wheel-type drifting car of convenient in carrying.

Invention main points of the present utility model are passenger vehicle type driver's cabin (1), motor (7), drifting device chassis of partial common (6) such as (3), and travel and the shared gearbox of drifting work (14).Transfer case (12) is distributed to drive axle with the power of motor (7) on demand by gearbox (14) output back one road, drive clutch collar by propons (9) and can make three bridges and drive (propons (9), jackshaft (10), back axle (8)), walk circuitous can engage when sunken in the differential lock that has of back axle overcome; Another road passes to the work of drifting device by power transmission shaft (13) with power.Foot brake, the hand brake, snub, exhaust brake quadruplet braking mechanism have travelled; Drifting work has the hand brake, pneumatic brake, mechanical brake three cover braking mechanisms.

The utility model is made up of passenger vehicle type driver's cabin (1), gas control check mechanism (2), drifting device (3), hydraulic system (4), hydraulic pressure leg (5), chassis (6), motor parts such as (7).(see accompanying drawing 1: shape assumption diagram).

Chassis (6) vehicle frame is for increasing the intensity of bearing complete vehicle weight, and consider the fixedly concentrated flimsy situation of after load of drifting device, go up laying two 16# i iron (21) at two girders (20) of vehicle frame, three 18# channel-section steels (22), become a plane with i iron, and shaping frame, i iron and vehicle frame fasten as one with U-bolt (17), bilateral symmetry is installed two groups of oblique supports (18), the steel plate of weighing (19) of a thick 60mm of lay is made big box plate on framework, below drifting device (3), be welded on the framework as base, (see accompanying drawing 2: body frame structure for automotive figure) with the steel plate (23) of two thick 60mm.

Motor (7) adopts 8120F type air-cooled diesel engine, and has cold start device in winter, and cold and water-deficient area are all had adaptability.Motor (7) is fastened on the support front end with stone bolt, and output shaft links to each other with gearbox (14) by clutch (15).

Passenger vehicle type driver's cabin (1) is placed in the support first half, indoorly takes 12 people, and the configuration living facilities.

Drifting device (3) is located in the barycenter of car load, and on the jackshaft (10), its base is with on the thick steel plate of bolton two 60mm above vehicle frame.Drifting device (3) mainly contains running part, drum braking part, air-path control system etc. and partly forms.Running part is made up of transfer case (12), power transmission shaft (13), reduction box (16), universal coupling (24), drum braking device (25), terminal reducer (26), drum clutch (27), cylinder parts such as (28).Transfer case (12) total power output shaft is imported reduction box (16) by power transmission shaft (13) with power with power, transmit terminal reducer (26) by universal coupling (24) again, pass to cylinder (28) by drum clutch (27), link by the steel cable on cylinder (28) and the May 4th assembly pulley on the derrick and working substance and to carry out work (seeing accompanying drawing 3, drifting device schematic diagram).

Drum braking partly is made up of left and right two groups of band brakes.Realize braking synchronously by balanced component, and can monolaterally adjust that operating mechanism is the hydraulic booster formula.Brake shoes adopts friction factor copper wire big, wear-resisting, heat-resisting, good braking performance and good to compile strong resin impregnation piece.

Air-path control system reaches reliable brake by the braking of two-chamber pump (32) intake and exhaust two-chamber.The air inlet braking is for travelling and stopping brake, and exhaust brake is for shutting down braking.Control section is placed in the driver's cabin front end, during the two-chamber brake portion is installed in, on the back axle.Its course of work is:

1, gas circuit (29) air inlet of connecting source of the gas charges into relay valve (30), and pressure is no more than the regulation operating pressure, enters the bleeder brake chamber of two-chamber pump (32) by threeway (31), keeps operating pressure, removes automatically; Enter relay valve (30) and unite two into one with gas circuit (29) pressure that connects source of the gas when connecting gas circuit (34) air inlet of control valve (33), pressure increases, and opens exhaust opening, and the pressure release of bleeder brake working chamber produces braking.

2, connect control valve (35) air inlet and enter quick release valve (36) and enter the inflation brake chamber of two-chamber pump (32), produce and brake by sebific duct (37); Bleed off the residual air of inflation brake chamber when dying by quick release valve (36), brake off.(seeing accompanying drawing 4, pneumatic diagram control schematic diagram).

The utility model is reasonable in design, and is easy to use and safe and reliable, is the comparatively ideal drifting car of oil well repairing operation.
