Abstract
Med en högtrycksvattenstråle avverkas ytskiktet på en yta (11) genom man anordnar två parallella gejdrar (12,13;51,52) parallellt mot ytan och monterar en matningsbalk (22) mellan gejdrarna och för en sprutenhet (33,34) i awerkningsvep fram och åter längs matningsbalken och stegar matningsbalken utmed gejdrarna för att awerka hela ytan. Man stegar matningsbalken (22) mellan två awerkningssvep genom att med två gripklor (40,41) mot varje gejder (12,13;51,52) samtidigt mot båda gejdrarna omväxlande låta den ena gripklon gripa och den andra vara lossad varvid man förflyttar den gripklo som inte har grepp en förutbestämd längd utmed gejdern.With a high-pressure water jet, the surface layer on a surface (11) is felled by arranging two parallel guides (12,13; 51,52) parallel to the surface and mounting a feed beam (22) between the guides and for a spray unit (33,34) and again along the feed beam and steps the feed beam along the guides to mow the entire surface. The feed beam (22) is stepped between two clearing sweeps by allowing one gripping claw (40,41) against each guide (12,13; 51,52) simultaneously against both guides to alternately grip one gripping claw and the other to be loosened, moving it gripping claw that does not have a grip of a predetermined length along the guide.

Figur 2 visar en förstorat detalj er av figur 1.Figure 2 shows an enlarged detail of Figure 1.
Figur 3 är en schematisk vy av en stegningsanordning visad i figur 1.Figure 3 is a schematic view of a frying device shown in Figure 1.
Figur 4 visar ett vattensprutaggregat anpassat för en rund pelare.Figure 4 shows a water spray unit adapted for a round pillar.
Beskrivning av visade utföringsformer av uppfinningen Figur 1 visar ett utsnitt av en konstruktion som kan vara av betong, exv en vertikal eller lutande del av en brokonstruktion vars yta 11 har försämrats så att den behöver förnyas. En ram är hopsatt av fyra rör 12-15 med fyra stöd 16-19 mot väggen. Stöden ingår i en anordning för att hålla ramen parallell mot väggen. Hela ramen visas hopbyggd av fasadställningselement men kan vara exempelvis en hopsvetsad ram.Description of illustrated embodiments of the invention Figure 1 shows a section of a construction which may be of concrete, eg a vertical or sloping part of a bridge structure whose surface 11 has deteriorated so that it needs to be renewed. One frame is composed of four tubes 12-15 with four supports 16-19 against the wall. The supports are part of a device to keep the frame parallel to the wall. The whole frame is shown assembled by façade scaffolding element but can be, for example, a welded frame.
Ramens två vertikala rör 12,13 utgör gejdrar för två gripanordningar 20,21 som bär en matningsbalk 22. Gripanordningama och matningsbalken visas separat som figur 2.The two vertical tubes 12,13 of the frame form guides for two gripping devices 20,21 carrying one feed beam 22. The gripping devices and the feed beam are shown separately as Figure 2.
Matningsbalken har två rör 30,31 som utgör gejdrar för en släde eller vagn 33 som bär en vattensprutlans 34 med ett sprutmunstycke riktad in mot betongytan. Vattensprutlansen får sitt högtrycksvatten från en pump via en slang 35. Släden med Vattensprutlansen gör ett avverkningssvep åt ena hållet med vattensprutlansen i en attackvinkel mot betongytan. Sedan vänder släden och gör ett avverkningssvep åt andra hållet med vattensprutlansen i attackvinkel åt det hållet. Vattensprutlansen oscilleras under avverkningssvepen tvärs slädens ritning för att ge större avverkningsbredd. Lämpligen är oscilleringen och slädhastigheten kopplade i ett fast förhållande på det sätt som beskrivs i svenska patentansökningen 0801398- 9. Mellan svepen stegas matningsbalken så att en ny yta träffas av vattenstrålen vid varje avverkningssvep eller efter ett bestämt antal avverkningssvep.The feed beam has two tubes 30,31 which form the guides for a carriage or carriage 33 which carries one water spray lance 34 with a spray nozzle directed towards the concrete surface. The water spray lance gets its high-pressure water from a pump via a hose 35. The slide with the water spray lance does one thing felling sweep in one direction with the water spray lance at an angle of attack to the concrete surface. Then turns the sledge and makes a felling sweep in the other direction with the water spray lance in angle of attack in that direction. The water spray lance is oscillated during the felling sweep across the sled drawing to provide greater felling width. Suitable are the oscillation and the sled speed coupled in a fixed relationship in the manner described in Swedish patent application 0801398- 9. Between the sweeps, the feed beam is stepped so that a new surface is hit by the water jet at each felling sweep or after a certain number of felling sweeps.
Varje gripanordning 20,21 har två gripklor 40,41 som kan förflyttas relativt varandra med hjälp av en hydraulcylinder 47 för stegning. Varje gripanordning 20,21 har ett fäste 36 för matningsbalken 22 En av gripanordningarna, gripanordningen 20, visas schematiskt som figur 3 och denna figur överensstämmer inte i utseende helt med gripanordningama som de ser ut i figur 2, men visar principen. Gripklorna 40,41 styrs av dubbelverkande hydraulcylindrar 43,44 som också dessutom har fjädrar 45,46 som hindrar gripanordningen att släppa taget om den blir helt trycklös. Gripanordningens fäste 36 för matningsbalken är monterat till övre gripklons hydraulcylinder 40 och en hydraulcylinder 47 är kopplad mellan hydralcylindrama 43,44, dvs mellan gripkloma. En slaglängdsjusterare i form av ett reglerbart stopp 48, visat som en stoppskruv, medger noggrann justering av hydraulcylinderns 47 slaglängd. Den noggranna justeringen är viktig eftersom matningsbalken armars kan hamna snett efter ett stort antal steg.Each gripping device 20,21 has two gripping claws 40,41 which can be moved relative to each other by means of a hydraulic cylinder 47 for frying. Each gripping device 20,21 has a bracket 36 for feed beam 22 One of the gripping devices, the gripping device 20, is shown schematically as Figure 3 and this Figure does not fully correspond in appearance to the gripping devices as they appear in Figure 2, but shows the principle. The grip claws 40,41 are controlled by double-acting hydraulic cylinders 43,44 as well in addition, springs have 45,46 which prevent the gripping device from releasing the grip if it becomes full pressureless. The gripping device bracket 36 for the feed beam is mounted to the upper gripping clone hydraulic cylinder 40 and a hydraulic cylinder 47 are connected between the hydraulic cylinders 43,44, ie between the grip claws. A stroke adjuster in the form of an adjustable stop 48, shown as a stop screw, allows accurate adjustment of the stroke of the hydraulic cylinder 47. The careful The adjustment is important because the feed beam arms can end up skewed after a large number of steps.
Matningsbalken 22 kan stegas genom att gripklon 41 kan förflyttas längs gejdern/röret 12 när den är fri men gripklon 40 är i gripläge. När gripklon 41 är i sitt nedre ändläge och har grepp och gripklon 40 har lossat sitt grepp kan hydraulcylindern 47 stega matningsbalken uppåt till dess hydraulcylindem når sitt ändläge. Sedan byter gripkloma grepp och hydraulcylindern 47 kan föra tillbaka gripklon 41 till sitt nedre ändläge som defineras av stoppet 48.The feed beam 22 can be stepped by allowing the gripping claw 41 to be moved along the guide / tube 12 when it is free but the gripping clone 40 is in the gripping position. When gripping claw 41 is in its lower end position and has gripping and gripping clone 40 has loosened its grip, the hydraulic cylinder 47 can step the feed beam upwards to its hydraulic cylinder reaches its end position. Then the gripping claws change grips and the hydraulic cylinder 47 can return the gripping claw 41 to its lower end position as they are reached by the stop 48.
Gripanordningen är nu i utgångslägeläge för ett nytt steg uppåt. På motsvarande sätt kan matningsbalken 22 stegas nedåt med undre gripklon i ett utgångsläge där den är i sitt övre ändläge.The gripping device is now in the initial position position for a new step upwards. Correspondingly, can the feed beam 22 is stepped downwards with the lower gripping claw in a starting position where it is in its upper end position.
Figur 4 visar ett vattensprutaggregat anpassad för en pelare som har rund tvärsektion och en övre och en undre gej der 51,52 som har ett antal stöd 53,54 som håller gej drama på plats parallellt med pelarens yta. För att förtydliga bilden visas inte pelaren. Matningsbalken 55 är likadan som matningsbalken 22 visad i figur 2 och den har gripanordningar 56,57 likadana som gripanordningama 20,21 i figur 2. Den vertikala matningsbalken 55 stegas runt pelaren.Figure 4 shows a water spray unit adapted for a pillar having a round cross section and one upper and a lower gej der 51.52 which has a number of supports 53.54 which keeps gej drama in place parallel to the surface of the pillar. To clarify the image, the column is not displayed. The feed beam 55 is similar to the feed beam 22 shown in Figure 2 and it has gripping devices 56.57 similar to as the gripping devices 20,21 in figure 2. The vertical feed beam 55 is stepped around the pillar.
Stödbenen 16-19 i figurl liksom stöden 53,54 i figur 4 utger del av bäranordningar för att hålla gej drama 12,13 respektive 51,52 parallella med ytan som ska bearbetas. Dessa bäranordningar måste hålla gej drama på plats och ta upp reaktionskrafterna från vattensprutmunstycket. Bäranordningama kan exempelvis vara i form av en lyftkran som bär ramen 12-19 respektive 53,54. Ramen kan också hängas i vajrar från en vinsch och reaktionskraftema kan tas upp av en byggnadsställning. Bäranordningania anpassas efter 4 möjligheterna på varje arbetsplats. En lyftkran kan exempelvis vara placerad ovanför ytan som ska bearbetas eller på marken under den.The support legs 16-19 in figure 1 as well as the supports 53,54 in figure 4 form part of support devices for keep gej drama 12,13 and 51.52 parallel to the surface to be machined. These Carriers must keep the drama in place and absorb the reaction forces from the water spray nozzle. The carrying devices may, for example, be in the form of a lifting crane carrying frames 12-19 and 53.54, respectively. The frame can also be hung in wires from a winch and the reaction forces can be absorbed by a scaffolding. The support devices are adapted accordingly 4 the opportunities in each workplace. A lifting crane can, for example, be placed above the surface to be worked or on the ground below it.
