Two-piston mechanical device of

Abstract

Mechanical device with two compression pistons facing each other for jackhammers, according to its innovative character, it contains two compression pistons, which face each other 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 pin with much more power, than single-piston devices. Overview

Description

Title of the invention: Mechanical device with two pistons

[0001] face-to-face compression for jackhammers.

[0002]

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

[0003] two compression pistons facing each other, for hammers

[0004] jackhammers, construction machinery, concrete breakers, and rock breakers.

[0005]

[0002] The vast majority of mechanical hammer devices

[0006] existing pickers on the market, are with a

[0007] compression piston, and many other devices still, in fact

[0008] for a large number of years, the devices with a piston

[0009] compression are predominant in the market of this type

[0010] tools, whether electric jackhammers, compressed air

[0011] hammers, thermal hammers, or construction machinery for breaking

[0012] rock and concrete, they have reached their limits in terms of

[0013] power and efficiency.

[0014]

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

[0015] first characteristic, it has two pistons of

[0016] compression, which face each other in the same cylinder,

[0017] the transmitter cylinder, which has the advantage of creating two

[0018] times more pressure in the receiver cylinder, which for the latter

[0019] contains the striking piston which will strike the spindle,

[0020] which allows to have more power and energy in

[0021] joules, than the devices with a compression piston, and

[0022] also to increase the frequency of strokes per minute, and

[0023] it is for all these reasons, which makes its innovative character.

[0024] According to its second characteristic, it comprises a transmission and synchronization mechanism

[0025] to allow movement to the entire mechanism.

[0027] According to its third characteristic, this device is

[0028] transposable to other types of jackhammers than those

[0029] with electrical energy, that is to say those with compressed air,

[0030] to thermal, and to construction machinery.

[0031]

[0004] According to certain embodiments this device may have

[0032] other transmission concepts, than that shown in the

[0033] overview, such as, for example, chain transmission,

[0034] gear transmission, shaft transmission,

[0035] belt transmission, cam transmission, its engine

[0053] must necessarily be more powerful, and it must also have cylinders, and pistons, and a reinforced mechanism, its manufacturing cost, should be a little higher, than what is offered on the current market, with more elements to assemble, but these disadvantages are compensated by its efficiency. The drawing represents the overall view, with the piston 1 and 2, facing each other in the transmitter cylinder 3, in the maximum position of their compression strokes, the striking piston 5, is in the low position in the receiver cylinder 4 which strikes the pin 6, the spring 14, allows the automatic raising of the pin and the striking piston, 12 and 13 the two connecting rods, the 7 the crankshaft, the 8, 9, 10, 11, the connecting arms. The innovative nature of this system also aims to reduce the duration of demolition projects, on the one hand, and on the other hand, to allow companies to offer their customers cheaper quotes.
