The termination of described inner-walls of duct sanding machine 36 is provided with for making the tapered Conic nozzle that is ejected into inner-walls of duct of abrasive material.
Described spray gun supporting mechanism 4 comprises bracing frame 28 and is arranged on the support reel assemblies 29 on support frame as described above 28, adjacent described support reel assemblies 29 is connected by the steel wire rope or the chain that are arranged in described support reel assemblies 29, and by steel wire rope or chain, is connected with the dolly roller stand 25 being arranged on described running trolley 2 near the support reel assemblies 29 of running trolley 2.Also can be in the support reel assemblies away from a running trolley spray gun supporting mechanism 4 foremost mounting spring clockwork spring it is connected with the track wheels 40 below bracing frame, thereby make it that certain driving force is provided, to drive spray gun supporting mechanism below to slide on rail system uniformly, while returning, by the rotation of dolly roller stand 25, regained, and then effectively guarantee to realize synchronously with running trolley, better play the effect of supporting spray gun.
The bilateral symmetry of support frame as described above 28 is provided with height adjuster 30, is evenly arranged with several V shaped wheels 31 on the axostylus axostyle between described height adjuster 30.Gun shot on spray gun assembly is set up in the V groove of V shaped wheel, thereby can effectively to spray gun assembly, position, the height that the height adjuster that support both sides arrange simultaneously can be set up spray gun is finely tuned, to the more effective injection of inner-walls of duct.
Described spray gun assembly also comprises sand-blast hose 32, and one end of described sand-blast hose 32 is connected with described gun shot 34 by spacer shell 33.The other end is connected with described sand-blasting machine 1.
Described rail system 5 comprises respectively for the light rail of spray gun supporting mechanism 4 mobile guides and the tooth bar for matching with described dolly driven unit 23.In running trolley 2 one end, design one group of fixing gunjet rack 26, and design and installation has many group spray gun fixture blocks 27, and have 3 groups of track wheel shafts combinations 22 respectively decile be arranged on the bottom of vehicle frame 21.Driven unit on running trolley can by be arranged on servomotor cog 24 with the tooth bar being arranged on rail system 5 between engage and the coordinating of track wheels 22 and light rail, by the control of outside electric-control system, realize the control to running trolley back and forth movement, spray gun supporting mechanism is erected on light rail simultaneously, and the spray gun assembly that relies on dolly to promote to set up on it is realized its synchronizing moving.
The drive motors that described driven unit 23 is used is servomotor, and described servomotor is connected with outside electric-control system.
Described sand-blasting machine 1 comprises shot-peening tank 11 and the pressure gas bag 19 being connected with described shot-peening tank 11, is provided with the abrasive material valve 12 and the intake valve 20 that are connected with described spray gun assembly 3 on described pressure gas bag 19.
Described sand-blasting machine 1 is connected with described outside electric-control system, and the work starting point place of described sand-blasting machine 1 directly over be provided with for the storage bin hopper to the interior interpolation ball of described shot-peening tank 11 material.As the preferred embodiment of the present embodiment, adjusting by outside electric-control system to servomotor, the running trolley that makes to be loaded with shot-peening tank moves to the work starting point place of sand-blasting machine, now the baiting valve on storage bin hopper and shot-peening tank seal valve are opened, ball material connects bucket by ball material and falls into shot-peening tank, after ball material is filled it up with, by being arranged on level-sensing device 15 transmission of signals on sand-blasting machine to PLC, PLC controls magnetic valve and drives baiting valve, it is closed, stop adding ball material in shot-peening tank, simultaneously also corresponding closing of shot-peening tank seal valve.PLC subsequently controlling run dolly moves along pipeline to workpiece direction with shot-peening tank and shot-peening spear, and when having moved to specking, shot-peening work starts, and starts shot-peening; When moving to stop-spraying point, shot-peening stop, shot-peening work completes; PLC subsequently again controlling run dolly with shot-peening tank and shot-peening spear, along pipeline, leave workpiece and get back to initial point, fill it up with ball material and repeat above work; Add spray gun in ball process and exited workpiece completely, operating personnel can carry out back works such as changing workpiece.It is according to the basic principle of inner-walls of duct surface treatment control that inner-walls of duct sandblast bead blasted surfaces is processed control model, technology controlling and process is mainly (as air pressure by its main technological parameter, spray speed, mixed ball ratio, spray is hit the time, number of times etc. is hit in spray) control the motion control being converted to spraying system, we adopt the control model of " spray gun motion " to implement the thinking of its technology controlling and process, adopt lance head front end that inner-walls of duct sanding machine is installed, the termination of inner-walls of duct sanding machine is designed to Conic nozzle, make abrasive material guiding form cone-shaped diffusion, thereby be ejected into inner-walls of duct.Spray gun motion is completed by the running trolley described in device, the scheme of its coupled modes is that the control model of " spray gun rotation and the running trolley synchronous uniform velocity motion of advancing; jet flow intensity is constant " is in order to guarantee the uniformity of workpiece strengthening region technological effect, bullet stream can not change too large to the spray hit intensity of hole inwall, thereby requires in design bullet stream constant to the jet length of hole inwall from shower nozzle.The feature of this mode is, the control of other technological parameter is fairly simple, and the process consistency of abrasive jet cleaning is good, but the structure that the lazy-tongs of shower nozzle and perflectometer make spraying system with control all very complicated.In shot-peening aperture, during less workpiece, because of shower nozzle and workpiece close together, can suitably reduce pressure and shot-peening time, in order to avoid workpiece can be injured, and there is the existing picture of spray, and not only can not reach the requirement of shot peening strengthening, reduced on the contrary the service life of workpiece.
Know-why of the present utility model has below been described in conjunction with specific embodiments.These are described is in order to explain principle of the present utility model, and can not be interpreted as by any way the restriction to the utility model protection domain.Based on explanation herein, those skilled in the art does not need to pay performing creative labour can associate other specific embodiment of the present utility model, within these modes all will fall into protection domain of the present utility model.
