Abstract

The utility model relates to a tractor directly connected air compressor engineering car. An air storage cylinder device which is formed by that a support bracket and the combined components of an air storage cylinder are welded into a whole is fixed on the beams of both sides of the front end of a tractor by the beams of both sides of the support bracket. The positioning of rabbets and the connection of flange plates are directly carried out by the traction device of the rear end of the gear box body of the tractor and the components of the host machine of an improved air compressor. A power output shaft is positioned behind the tractor. The spline connection and the power driving can be directly carried out by using the splined hole of the power output shaft and the spline of the shaft end of the crank shaft of the improved air compressor. The tractor directly connected air compressor engineering car has the advantages of simple structure, convenient movement, low cost and high work efficiency.

Description

Tractor directly connected air compressor engineering car

The utility model relates to the compressed-air power source that a kind of construction operation is used, particularly a kind of tractor directly coupled type air compressor engineering truck.

At present, the air compressor unit of in various construction operations, using, basically utilize air compressor and coupling, speed-change gear box, internal-combustion engine to be connected in series on the same frame, carry out the direct connection transmission, or with the power spindle nose laid parallel of air compressor, be installed in parallel on same frame, carry out belt transmission.This air compressor unit is divided fixed or towed two kinds, need join special-purpose vehicle and transport dress or traction.

The purpose of this utility model provides a kind of tractor directly coupled type air compressor engineering truck, and it is simple in structure, conveniently moving, and cost is low, the operating efficiency height.

The purpose of this utility model is achieved in that this device is at the fixing gas receiver device of tractor front end, its rear end directly connects and motivational drive with improved air compressor host part, wherein, utilize support bracket both sides side bar to be fixed on the side bar of tractor front end both sides by the gas receiver device of support bracket and gas receiver component seam one; Utilize gear box of tractor body rear end traction gear and improved air compressor host part directly to carry out seam location and flange plate connects; The rearmounted pto of tractor utilizes its splined hole and improved air compressor crank axle head spline directly to carry out key connecting and motivational drive.

Because being the tractor and the improved air compressor host part of the novel transmission traction device of having of CN90219422.4, the utility model employing patent No. directly connects and motivational drive, at the tractor front end gas receiver device that is fixedly connected, form the pressurized air engineering truck,, have compact structure, simple so overcome the shortcoming of prior art, cost is low, total arrangement is reasonable, maneuverability, conveniently moving during use, the advantage that operating efficiency is high is easy to apply.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is the utility model structural representation.

Fig. 2 is a frame of broken lines interior profile rear view among Fig. 1.

9 is that the employing patent No. is 90219422.4 the tractor with novel transmission traction device in the accompanying drawing, and its front end is fixedly connected and is made of the gas receiver device of one support bracket 10 and gas receiver component 11.The both sides side bar is fixedly connected on the lengthening side bar of tractor 9 front end vehicle frame both sides on the support bracket 10, and gas receiver component 11 is welded as a whole with support bracket 10.Gearbox casing 1, seam positioning shaft bearing 2, have link plate 3 behind the mounting flange, the rearmounted pto 7 of spline cellular type is tractor 9 original structure parts.Two-sided connecting flange disc type bearing support 4 on the air compressor 8 after the improvement, its right-hand member carries out the seam location with air compressor body shell 8 and connects, position by stop portion A between left end and the part 2, utilize bolt 6 to connect screw with respective flange dish on the part 3 and carry out fastening connection by the flange tie-plate hole on the part 4.Air compressor crank 5 left ends utilize bearing to be positioned on the part 4, its left end spindle nose, be processed into (or adopting singly-bound to connect) in spline inserting member 7 splined holes, because of reaching between part 2 and the part 4 between part 7 and the part 2 the coaxality technical requirements is arranged, thereby guaranteed part 5 and part 7 splined shafts and hole centering coaxality requirement in the assembly process.Therefore the tractor directly coupled type air compressor engineering truck of forming by this structure, have simple in structure, total arrangement is reasonable, maneuverability, transmission efficiency height, characteristics such as the operation cost is low.As mix corresponding pneumatic tool, can be widely used in departments such as municipal engineering, highway construction, capital construction, mine construction.
