Autor vynálezu Šmída ladislav mg., Prievidza (54) 2ariadenie na ovládanie bremien 1Author of the invention Šmída ladislav mg., Prievidza (54) 2 load control device 1

Predmetom vynálezu je zariadenia na ovládanie bremien určené predovšetkým na ovládanieosového pohybu vrtných tyčí u rotečných vrtných súprav.It is an object of the invention to provide a load control device intended primarily for controlling the movement of the drill rods in rotary drilling rigs.

Doslal známe zariadenia na ovládanie bremien sú riešené epravidla ako jednostupňovéválce a velkou zastavovacou dížkou.The well-known load control devices have been designed as a single-stage cylinder and a large stopper.

Riešenie zariadeni formou dvojstupňového, alebo viaestupňového valca nepĎsobia ako dvoj-činná, ale ich spštný chod zabezpečuje vlastná hmotnoať břemena. Salšie eú riešené tak, žepřívody kvapaliny eú vedené na obidve atrany valca, čo zhoršuje konštrukciu a zdražuje ich výrobu.The solution of the device in the form of a two-stage or a multi-stage cylinder does not act as a double-acting cylinder, but its self-acting load ensures its own weight. The other eu solutions are designed so that the eu fluid supply is directed to both the cylinder atran, which deteriorates the construction and makes the production thereof more expensive.

Horeuvedené nedostatky sú odstránené zariadenim na ovládanie bremien podlá vynálezu,ktorého podstata spočívá v tom, že na púzdre opatrenom dvorná kanálmi je upevněné středovérúrka spojená so spodným pieetom, ako aj vnútorná piestnica, ktoré je na druhej straněopatřená otvorom a je upevněná na spodný pieet, pričom piestnica je upevněná na plést. Týmto ríeěením sa dosiahne zníženie zastavovacej dížky zariadeni. Súčaane sa doslahnedvojčinnosť teleskopického zariadenia, čo Je predovšetkým výhodné pri vrtacích prácach,pretože sa umožňuje přítlak, ale tiež vytiahnutie vrtnej tyče z vývrtu.The aforementioned drawbacks are eliminated by the load-controlling device according to the invention, which is characterized in that a central tube connected to the lower pieet and an inner piston which is on the other side fixed by the opening and fixed to the lower pieet are mounted on the housing. the piston is fixed to knit. This solution achieves a reduction in the stopping distance of the device. The synergy of telescopic equipment has been combined, which is particularly advantageous in drilling operations, since downforce is possible, but also the drill rod is withdrawn from the bore.

Riešenim obidvoch kanálov v jednom púzdre a zariadenim etredovsj rúrky sa doelahne koncen-trácie prívodných armatúr, reap. hadic do jedného mleata, čím sa zjednoduší konštrukcia 199 054By addressing the two channels in one housing and the tube tube, the concentration of the inlet fittings, reap. hoses to one mill, thereby simplifying the construction of 199 054

Claims

Load control devices for drilling operations in particular, characterized in that it comprises a housing (1) provided with a central channel (2) and a channel (3), wherein a central tube (4) connected to the lower piston (5) is mounted on the housing (1). as well as an inner pie (10) which is provided with at least one opening on the second side and is fixed to the epode pieet (5), the rod (11) provided with at least one opening being fixed to the pieat (8).
