Abstract

The mounting comprises a first frame for securing to the lifting arms and a second frame which is secured inside the first frame via a rotary fastener (19). One or two hydraulic cylinders (36) are used to rotate the frames relative to each other and allow a tool held inside the second frame to be tilted sideways. The rotary fastener is located in the lower parts of the frames. The hydraulic cylinders are coupled between the two frames and located above a window (18, 22) in the frames.

Description

523 941 a.. .- 2 / Detaljbeskrivning av visat utföringsexempel Figur 2 visar främre delen av två lyftarmar 12,13 på en hjullastare. På armarna är en bakre ram 14 av ett redskapsfäste monterat med sina övre och undre fästöron 15,16 på sedvanligt sätt. Denna rams huvuddel utgörs av en kraftig plåt 17 som har en stor central öppning 18. l centrum och i sin nedre del har plåten 17 ett vridfäste 19 som bär en främre ram 20, som också har en kraftig plåt 21 som sin huvuddel. Vridfästet 19 består av två korta rörbitar med den ena lagrad i den andra. Vridfästets ena rörbit är fäst i ena plåten 17,21 och den andra rörbiten är fäst i den andra av plåtarna. 523 941 a .. .- 2 / Detailed description of shown embodiment Figure 2 shows the front part of two lifting arms 12,13 on a wheel loader. On the arms, a rear frame 14 of a tool holder is mounted with its upper and lower fastening ears 15,16 in the usual manner. The main part of this frame consists of a strong plate 17 which has a large central opening 18. In the center and in its lower part the plate 17 has a pivot bracket 19 which carries a front frame 20, which also has a strong plate 21 as its main part. The swivel bracket 19 consists of two short pieces of pipe with one mounted in the other. One piece of pipe bracket is attached to one plate 17,21 and the other piece of pipe is attached to the other of the plates.

Vridfästets vridaxel har betecknats I. Plåten 21 har också en öppning 22 som överensstämmer med öppningen 18 Den främre plåten 21 har på var sida två vertikala plåtar 24,25 respektive 26,27 till vilka redskapen ska fästas på ett standardiserat sätt så att olika typer av redskap kan fästas på dem. För att täcka alla typer av redskap är på var sida en tredje kortare vertikal plåt 28,29 påsvetsad på främre plåten. Mellan de tre vertikala plåtarnas övre ändar är på var sida stänger 30, 31 insatta på vilka redskapen hängs och sedan låses med tappar 32,33 i nederändarna. Dessa tappar 30,33 styrs hydrauliskt med en hydraulcylinder 34 inuti ett balkformat skydd 35.The pivot axis of the pivot bracket has been designated I. The plate 21 also has an opening 22 which corresponds to the opening 18. The front plate 21 has on each side two vertical plates 24,25 and 26,27 to which the tools are to be fastened in a standardized manner so that different types of gear can be attached to them. To cover all types of tools, a third shorter vertical plate 28,29 is welded on each side on the front plate. Between the upper ends of the three vertical plates, on each side, rods 30, 31 are inserted on which the tools are hung and then locked with pins 32,33 in the lower ends. These pins 30,33 are hydraulically controlled by a hydraulic cylinder 34 inside a beam-shaped guard 35.

En hydraulcylinder 36 med genomgående kolvstång är kopplad med sina kolvstångsändar i främre plåtens 21 vertikalplåtar 25,26 och cylinderhuset är kopplat till en tapp 37 fäst i bakre plåten 17. Tappen 37 sträcker sig genom en bågforrnad öppning 38 ifrämre plåten. Med hydraulcylindern kan man således vrida främre plåten 21 relativt bakre plåten 17 en vinkel som är större än 15 grader åt båda håll från det visade normalläget. Hydraulcylindern 36 är skyddad i ett balkformigt skydd 41, men i figuren visas hydraulcylindern med heldragna linjer trots att den egentligen är skymd av skyddet 41. I redskapsfästets visade normalläge är hydraulcylindern 36 horisontell.A hydraulic cylinder 36 with a continuous piston rod is connected with its piston rod ends in the vertical plates 25,26 of the front plate 21 and the cylinder housing is connected to a pin 37 attached to the rear plate 17. The pin 37 extends through an arcuate opening 38 in front of the plate. With the hydraulic cylinder, the front plate 21 can thus be rotated relative to the rear plate 17 at an angle greater than 15 degrees in both directions from the normal position shown. The hydraulic cylinder 36 is protected in a beam-shaped protection 41, but in fi guren the hydraulic cylinder is shown with solid lines even though it is actually obscured by the protection 41. In the normal position of the implement bracket shown, the hydraulic cylinder 36 is horizontal.

De båda plåtarna 17, 21 har cirkulärt bågformade övre delar 39 respektive 40 och den främre plåten 21 har ett överfall 42 som håller ihop plåtarna 17,21 och har glidyta mot den bakre plåten 17. 523 941:~1=:11f-..=f f " n. »- 3 Figur 4 motsvarar överdelen av figur 1 och den enda modifieringen är att hydraulcylindern 36 ersatts av två hydraulcylindrar 43,44 vilket ger större vridkraft eftersom hydraulcylindrarna samverkar. Cylindern 43 är kopplad mellan vertikalplåten 25 på främre plåten 21 och bakre plåtens 17 tapp 37, och cylindern 44 är kopplad mellan vertikalplåten 26 på främre plåten 21 och tappen 37. De två cylindrarna 43,44 behöver inte vara helt horisontella, utan kan vinklas något mot varandra, men detta minskar effektiva siktöppningen 18,22.The two plates 17, 21 have circularly arched upper parts 39 and 40, respectively, and the front plate 21 has an abutment 42 which holds the plates 17,21 together and has a sliding surface against the rear plate 17. 523 941: ~ 1 =: 11f- .. Figure 4 corresponds to the upper part of Figure 1 and the only modification is that the hydraulic cylinder 36 is replaced by two hydraulic cylinders 43,44 which gives greater torque as the hydraulic cylinders cooperate. The cylinder 43 is connected between the vertical plate 25 on the front plate 21 and the pin 37 of the rear plate 17, and the cylinder 44 is connected between the vertical plate 26 of the front plate 21 and the pin 37. The two cylinders 43,44 do not have to be completely horizontal, but can be angled slightly towards each other, but this reduces the effective sight opening 18,22.

Det bör observeras att alla mått inte exakt överensstämmer mellan de olika figurerna.It should be noted that not all measurements correspond exactly between the different figures.

Placeringen av vridfästet 19 i ramarnas underdelar och vrid cylindern 36 resp.The placement of the swivel bracket 19 in the lower parts of the frames and turn the cylinder 36 resp.

Vridcylindrarna 43,44 medför att man kan få en stor siktöppning genom plåtarnas 17,21 öppningar 18,22. Denna siktöppning är väsentlig när redskapet är en pallgaffel eller en kranarm eftersom man då ofta har maskinens armar 12, 13 höjda så att redskapsfästet kommer i slktlinjen framåt. När redskapet är en snöskopa och man exempelvis rensar längs en trottoarkant kommer skopan att förskjutas minimalt i sidled när man skevar skopan, dvs vrider främre ramen 40 i axeln I så att skopan kommer att luta i sidled. Det är en än större fördel vid markplanering att man har så liten sidorörelse på planeringskopan vid skevning.The rotating cylinders 43,44 mean that a large screen opening can be obtained through the openings 18,22 of the plates 17,21. This sight opening is essential when the implement is a pallet fork or a crane arm, since the arms 12, 13 of the machine are then often raised so that the implement attachment comes forward in the line. When the implement is a snow shovel and you, for example, clear along a curb, the bucket will be displaced minimally laterally when you skew the bucket, ie turn the front frame 40 in the shaft I so that the bucket will tilt sideways. It is an even greater advantage in ground planning that you have so little lateral movement on the planning bucket when skewing.
