Two-piston mechanical device

Abstract

Mechanical device with two facing pistons for jackhammers, according to its innovative character contains two facing pistons, in the transmitter cylinder, which has the advantage of creating twice as much pressure in the receiver cylinder, which contains the striking piston which will strike the spindle with much more power, than single-piston devices.

Description

Title of the invention: Mechanical device with two pistons

[0001] Face to face for jackhammers.

[0002]

[0001] The present invention relates to a mechanical device with

[0003] two pistons facing each other, for jackhammers, machines

[0004] of concrete and rock breaking construction sites.

[0005]

[0002] The vast majority of mechanical hammer devices

[0006] existing pickers on the market, are single-piston and well

[0007] other devices still, in fact since a large number

[0008] years, single-piston devices are predominant on the

[0009] market for this type of tool, whether jackhammers

[0010] electric, compressed air, thermal, or engines of

[0011] rock and concrete breaker sites, they have reached their limits in

[0012] power and efficiency term.

[0013]

[0003] This device allows to resolve this limit, because according to its

[0014] first characteristic, it is designed with two pistons which

[0015] face each other in the emitting cylinder, which has the following

[0016] advantage of creating twice as much pressure in the cylinder

[0017] receiver, which for the latter contains the striking piston which

[0018] will hit the spindle, which allows for more power

[0019] and energy in joules, than single-piston devices, according to its

[0020] second feature, it has a transmission mechanism

[0021] and synchronization, to allow the movement of everything

[0022] the whole mechanism, according to its third characteristic,

[0023] this device can be transposed to jackhammers,

[0024] electric, compressed air, thermal, and to the engines of

[0025] construction site.

[0026]

[0004] According to certain embodiments this device may have

[0027] other modes of transmission, than that shown on the

[0028] drawing, such as for example, chain, shafts, belts,

[0029] gears, and cams, and the fact that it has twice as much

[0030] pressure, its engine must necessarily be more powerful, and it

[0031] must also have cylinders, and pistons, and a

[0032] reinforced mechanism, its manufacturing cost, should be a

[0033] slightly higher than what is offered on the current market,

[0034] plus double the number of elements to assemble, but these disadvantages

[0035] are offset by its effectiveness.

[0047] The drawing represents the overall view, with piston n°1 and n°2, facing each other in the transmitter cylinder n°3, in the maximum positions of their compression stroke, the striking piston n°5, is in the low position in the receiver cylinder n°4 which strikes the pin n°6, the spring n°14, allows the automatic raising of the pin and the striking piston, n°12 and n°13 the two connecting rods, n°7 the crankshaft, n°8 n°9 n°10 n°ll, the connecting arms. The innovative nature of this system also aims to reduce the duration of demolition work, on the one hand, and on the other hand, to allow companies to offer their customers cheaper quotes.
