Abstract

A plunger-type self-propelled walking highway marking machine is used for marking a highway, and is supplied with power by an engine [11] and a gearbox [10], and a travelling wheel [5] and a plunger pump [9] are respectively driven to move by a chain wheel [6] and an eccentric wheel [8] on an output shaft of the gearbox [10 ]. The traveling wheel drives the scribing machine to travel, the plunger pump (9) pumps high-pressure coating to the nozzle (18) for scribing, and a pressure stabilizing energy storage device (12) is arranged in the paint spraying system to ensure that scribed lines are clear and smooth. The width of the drawn line can be adjusted within the range of 100-300 mm, and the line can be realized only by replacing the nozzles (18) with different types.

Description

Plunger type self-propelled hand highway traffic line marking machine

A kind of hand steered voluntarily highway-lineation machine of plunger type that relates to is used for the line of road, belongs to road and makes things convenient for use equipment.

Existing road line marker has multiple form of structure, the automatic pen machine of arterial highway, though automaticity is higher, function is complete, costs an arm and a leg, and non-general maintain road unit-economy ability can bear.The hand held pen machine, cost and price are lower, but in the prior art, the line lacquer adopts diaphragm pump for lacquer, spray paint by nozzle, because the diaphragm vibration frequency of diaphragm pump is higher, diaphragm damages fast, as long as diaphragm has damage slightly, the pressure that sprays paint is just unstable, thereby causes the film thickness inequality, the unintelligible smoothness of the lines that mark, influence line quality, transmission pipe drawback such as easily break.

In view of this, the purpose of this utility model just is to provide a kind of pressure stability of spraying paint, and it is neat to mark that the lines flow smoothly, and the hand steered voluntarily highway-lineation machine of plunger type that can control of line thickness.

It drives sprocket wheel and road wheel voluntarily by engine mission the utility model, utilize the eccentric wheel of gear box output end to drive plunger displacement pump pumping high pressure lacquer,, lead by pointer through energy-storing device and overflow valve is stable and control is sprayed paint pressure, handgrip is controlled the line of spraying paint, and realizes above-mentioned purpose with this.

Below in conjunction with drawings and Examples in detail, operating principle of the present utility model and architectural feature are described in detail.

Description of drawings

Fig. 1 is a major side views of the present utility model

Referring to Fig. 1, the utility model is mainly by vehicle frame, power transmission, paint spraying system, four parts that lead are formed, main member is: vehicle frame partly comprises handle ［ 1 ］, underframe ［ 3 ］, directive wheel ［ 4 ］, road wheel ［ 5 ］, motivation transfer motion part comprises sprocket wheel ［ 6 ］, chain ［ 7 ］, eccentric wheel ［ 8 ］, gearbox ［ 10 ］, motor ［ 11 ］, paint spraying system comprises plunger displacement pump ［ 9 ］, energy-storing device ［ 12 ］, overflow valve ［ 13 ］, pressure meter ［ 14 ］, paint can ［ 15 ］, drive link ［ 16 ］, nozzle support ［ 17 ］, nozzle ［ 18 ］, discharge valve ［ 19 ］, joystick ［ 2 ］, and guiding indicating pointer ［ 20 ］ constitutes.

Handle ［ 1 ］ is made by steel pipe, the one end is connected with underframe ［ 3 ］, directive wheel ［ 4 ］ is a rubber tire, it is fixed in the central authorities at underframe ［ 3 ］ rear portion, in order to the direction of control pen machine walking, totally two of road wheels ［ 5 ］, walk and be set with gear on its wheel shaft in the left side, the coaxial meshed transmission gear of gear and hinge wheel ［ 6 ］, ground-engaging wheel ［ 5 ］ motion.Sprocket wheel ［ 6 ］ has each one of size, and minor sprocket ［ 6 ］ is fixed on the output shaft of gearbox ［ 10 ］, drives hinge wheel ［ 6 ］ by chain ［ 7 ］ and rotates.The output shaft of gearbox ［ 10 ］ also is set with eccentric wheel ［ 8 ］, and the upper end of plunger displacement pump ［ 9 ］ links to each other with eccentric wheel ［ 8 ］, moves by the widely different transhipment of eccentric wheel ［ 8 ］ to become pumping of plunger displacement pump ［ 9 ］, to realize the suction and the pumping of paint.The paint pressure that is come out by plunger displacement pump ［ 9 ］ has reached 8～10Mpa, but its oil pressure still has pulsating nature, for keeping the loss of dispersing of all even spray of line film thickness pearl little, so in paint spraying system, be provided with parallel bitubular energy-storing device ［ 12 ］ and overflow valve ［ 13 ］, make the pressure stability of spraying paint.The pressure that no matter sprays paint is below or above the pressure that sprays paint that defines, and all can make by energy-storing device ［ 12 ］ and overflow valve ［ 13 ］ and spray paint pressure stability in the value of defining scope, thereby make the adhesive power that sprays paint strengthen the film thickness homogeneous.Energy-storing device ［ 12 ］ and overflow valve ［ 13 ］ are delivered to nozzle ［ 18 ］ by the high-pressure airless lacquer that energy-storing device ［ 12 ］ comes out through pipeline for connecting, and the keying of nozzle ［ 18 ］ is controlled by the joystick ［ 2 ］ and the drive link ［ 16 ］ that are fixed on the handle ［ 1 ］.Be the understanding pressure that sprays paint, therefore be in series with pressure meter ［ 14 ］ in the pipeline of energy-storing device ［ 12 ］, paint can ［ 15 ］ is fixed on the front end of underframe ［ 3 ］, in be provided with filter screen and add the lacquer lid, bottom dress discharge valve ［ 19 ］ is for the residual lacquer of drainage and clean and use.Paint can ［ 15 ］ can be processed into cylindrical shape, also can be processed into the container of its geometry, nozzle ［ 18 ］ is installed in the right side of underframe ［ 3 ］ front end, it is fixed on the nozzle cradling piece ［ 17 ］, cradling piece ［ 17 ］ also is fixed in the right side of underframe ［ 3 ］ front end, and an end of drive link ［ 16 ］ also is fixed on the cradling piece ［ 17 ］.Nozzle ［ 18 ］ has different model, and its jet width can be regulated in 100～300 millimeters scopes, to satisfy the different needs of line thickness.The guiding of line is decided by the guiding indicating pointer ［ 20 ］ that is contained in underframe ［ 3 ］ front end right side, guiding indicating pointer ［ 20 ］ moves along old line or baseline, guiding indicating pointer ［ 20 ］ is parallel side by side with nozzle ［ 18 ］, guiding indicating pointer ［ 20 ］ is fixed in the right side foremost of underframe ［ 3 ］, be positioned at the inboard of nozzle ［ 18 ］, both distances keep constant, and therefore the lines that mark are neatly smooth.Motor ［ 11 ］ is installed in the rear portion of underframe ［ 3 ］, the middle part of gearbox ［ 10 ］ fixed frame ［ 3 ］, and all device all is fixed on the underframe ［ 3 ］, by road wheel ［ 5 ］ and directive wheel ［ 4 ］ supporting walking.

The utility model is through test, it is clear, uniform to mark that the lines flow smoothly, flexible to operation, the various line that arterial highway also can be used for secondary highway and urban road had both been can be used for, not only available highway marking, also can do in the line in other utilities building places, be particularly suitable for ground county road section and use.
