Abstract

Device for splitting of a block of stone. The device comprises a wedge (1) which is connected with a hammer device (2) comprising a hammer piston movable to-and-fro. The wedge has length (L1) which is at least equal to the length (L2) of the hammer piston (3).

Description

Föreliggande uppfinning hänför sig till en anordning för spräckning av stenblock vid vilken en kil användes för att åstadkomma spräckverkan. The present invention relates to a device for cracking boulders in which a wedge is used to effect cracking action.

Vid en förut känd anordning för spräckning av stenblock, se exempelvis US-A 4168862, anordnas ett verktyg i ett förborrat hål. Därefter drivs en kil in mellan fjädrar för att åstadkomma spräckverkan. Denna anordning har den nackdelen att den är förhållandevis långsam. Dessutom har man nackdelen att man måste ha dels en bergborrmaskin för att borra hålet och dels ett verktyg med tillhörande hydraulaggregat för spräckningen. In a prior art device for cracking boulders, see for example US-A 4168862, a tool is arranged in a pre-drilled hole. A wedge is then driven in between springs to provide a cracking effect. This device has the disadvantage that it is relatively slow. In addition, you have the disadvantage that you must have a rock drilling machine to drill the hole and a tool with associated hydraulic units for the crack.

Föreliggande uppfinning, som definieras i efterföljande patentkrav, syftar till att åstadkomma ett verktyg medelst vilket stenspräckningen blir avsevärt snabbare samtidigt som man undviker användandet av ett separat hydraulaggregat för själva spräckningen. The present invention, which is defined in the appended claims, aims to provide a tool by means of which the rock cracking becomes considerably faster while avoiding the use of a separate hydraulic assembly for the cracking itself.

Ett utföringsexempel av uppfinningen beskrivs nedan med hänvisning till bifogade ritning som schematiskt visar anordning för spräckning av stenblock enligt uppfinningen. An embodiment of the invention is described below with reference to the accompanying drawing which schematically shows a device for cracking boulders according to the invention.

Den på ritningen visade anordningen för spräckning av stenblock innefattar en kil 1 som medelst en stång 4 är förbunden med ett slagverk 2. Slagverket 2 innefattar en fram och åter rörlig slagkolv 3 som drivs på sedvanligt sätt. Kilen 1 sticks vid spräckning av stenblocket 5 in i ett borrhål 6. Kilen 1 har en längd Ll och slagkolven 3 längden L2. Kilens 1 längd L! skall vara minst lika med längden L2 hos slagkolven 3. Genom detta utförande fås en effektiv överföring av stötvågsenergi från slagkolven 3 till kilen 1. Detta ger en snabb och effektiv spräckning av stenblocket 5. The device shown in the drawing for cracking boulders comprises a wedge 1 which by means of a rod 4 is connected to a percussion device 2. The percussion device 2 comprises a reciprocating percussion piston 3 which is driven in the usual manner. When cracking the boulder 5, the wedge 1 is inserted into a borehole 6. The wedge 1 has a length L1 and the percussion piston 3 a length L2. Wedge 1 length L! shall be at least equal to the length L2 of the percussion piston 3. This design provides an efficient transfer of shock wave energy from the percussion piston 3 to the wedge 1. This provides a fast and efficient cracking of the boulder 5.
