Description

The invention relates to the field of engineering (manufacturing and operation of pile-driving tubular hammers).

In construction, for driving piles that serve as the foundation for future industrial buildings or residential buildings, especially effective in seismic zones, various types of piling hammers are used: diesel rod hammers, diesel tube hammers, hydraulic rod and tube hammers.

Structurally simple diesel tubular hammers of various modifications with a mass of the impact part: 250-1800-2500-3200 kg were widely used in construction.

For the operation of tubular hammers, hammer machines of an appropriate height and carrying capacity are required.

For example, for the SP77A model pile driving diesel Hammer having a mass of the impact part of 2500 kg, the SP49D copra machine shown in Fig. 1 is used, which allows driving piles up to 12 meters long with a weight of up to 5 tons.

The structure of this pile driver (SP49D) includes - a tractor 1 (T-10B), converted for a hinged part and a pile equipment, including: a movable frame 2, hydraulic equipment 3, a supporting frame 4, side braces 5, hydraulic shear 6, rear brace 7, mast 8, head 9, Hammer 10 (СП77А), headgear 11, pile arrow 12, stop 13 and device for pulling piles 14. The power drive is a stand-alone hydraulic, where a pump with a capacity of Q _n = 150 l / min provides pressure p _n = 12 MPa.

The machine is controlled from the tractor cab.

Diesel tubular hammers belong to the pile driving hammers with free fall of the shock part and atomization of fuel by the nozzle, and at the same time have the same type of device (see figure 2).

The main working (shock) part of the Hammer is a piston, which moves in the pipe-cylinder and strikes at the Shabot, which closes the cylinder from below. Shabbot transfers the piston blow to the pile through the headgear and is the most loaded part operating at high temperature. The tubular Hammer also includes the following components: a fuel system with a fuel tank and a plunger pump, a lubrication system with an oil tank and a plunger pump, a cat is a device designed to start the Hammer diesel engine into operation.

The tubular diesel Hammer shown in FIG. 2 includes: a piston 1 with piston rings 2, which is located in

cylinder tube 3, rigidly connected by means of bolts 4, with guide tube 5, shabot 6 with piston rings, upper 7 and lower 8 bearings, which are guides for the shabot, ring shock absorbers 9, shock absorbers 10, holder 11, rigidly attached with 12 to 3 screws , a fuel pump 13 and a fuel tank 14, rigidly attached to the pipe-cylinder 3, an oil pump 15 with an oil tank 16 and oil pipes 17-18 which are also rigidly attached to the pipe-cylinder 3, a fuel flow control mechanism 19 mounted on the fuel pump 13, cat 20, moving about mounted on the guides 21, rigidly bolted 22 to the guide tube 5, the emphasis of the platoon 23 of the cat and the emphasis of the discharge 24 of the cat, which are also rigidly fixed on the guides 21, the capture of the upper 25 and the capture of the lower 26 are rigidly attached respectively to the guide pipe 5 and cylinder pipe 3, water tank 27 with drain neck 28, exhaust pipe 29, which is used to purge cylinder pipe 3, retaining ring 30 mounted on piston 1, restricting the maximum piston stroke upward, cover 31, closing the upper end face to the right yayuschey pipe 5 during transportation Hammer ear 32 for transporting Hammer.

The fuel pump, which is part of the tubular Hammer, which is shown in figure 3, includes: lever 1, plunger 2, sleeve 3, clamp 4, pump housing 5, o-ring 6, retainer 7, sealing cuff 8, spring 9, plunger - pusher 10, ball valves 11 and 12, valve body 13,

valve spring 14, adjusting flange 15, seat 16, fitting 17 and axis 18.

The fuel pump (figure 3), which is designed to supply fuel to the combustion chamber of the tubular Hammer, operates as follows.

When moving downward through the lever 1 of the fuel pump drive (Fig. 3), the tubular Hammer piston (Fig. 2) presses on the plunger 2, which when lowering creates pressure in the pump cavity, closing the valve 12 in the fitting 17 and begins to displace fuel through the return ball valve 11 through the fuel line to the combustion chamber of the Hammer, where the fuel flashes and the piston is thrown up to a height depending on the amount of fuel supplied. During the upward movement of the Hammer piston, the plunger 2 rises up by the action of the spring 9, the check ball valve closes by the action of the spring 14, and the upper ball valve 12 opens, filling the fuel pump cavity again with fuel through the fuel supply from the Hammer fuel tank.

The fuel pump has the ability to control the fuel supply. When you turn the adjusting flange 15 counterclockwise, the amount of fuel supplied to the combustion chamber decreases, clockwise - increases.

The oil pump, which is part of the tubular Hammer, which is shown in figure 4, includes: body 1, top fitting 2 with an integrated ball valve (not shown), axis 3, lever 4, plunger 5, spring 6, valve body 7 ring

sealing 8, cotter pin 9, lower connection 10 with integrated ball valve (not shown).

As can be seen from figure 3 and figure 4, the device and the principle of operation of the fuel and oil pumps are similar.

Lubrication of the tubular diesel Hammer is as follows. The Hammer piston, when moving downward through the lever 4 (Fig. 4), presses the plunger 5, pressure is created in the cavity of the oil pump and the oil pipe, while the ball valve 11 is closed (Fig. 5) and the ball valves 12 and 13 open, providing oil supply, displaced by the plunger through the oil pipe to the Hammer piston and shabot.

When the pusher 5 returns to its original position, the non-return ball valves 12 and 13 are closed, and the ball valve 11 is opened and the system is refilled from the oil tank through the oil line.

Cat (Fig.6) - is a lifting device necessary for lifting the piston and putting the diesel tubular hammer into operation. The cat is mounted movably on the guides 21 of the Hammer (figure 2), rigidly bolted 22 to the guide tube 5 of the tubular Hammer. The cat (Fig.6) includes: hook 1, finger 2, cocking and reset lever 3, lock 4, spring 5, plug 6, spline roller 7, spline lever 8, cheek 9, body 10, finger 11, locking screw 12.

To launch the Hammer into operation, the cat’s hook 1 (Fig. 7) is hooked to a special groove in the form of a shoulder made on the Hammer piston, i.e. the piston is gripped, followed by a cable,

fixed to the finger 11, with the help of the Kopra Cat chain hoist, the cat rises up, where, using special stops installed on the Hammer guide tube (Fig. 2), the piston is automatically reset, resulting in fuel injection into the combustion chamber, where high pressure occurs from air compression and there is an outbreak of the fuel mixture, which throws the piston up. The working Hammer stops by the tension of the rope, for the ring attached to the lever 1 (Fig. 3) of the fuel pump, which turns off the fuel supply to the combustion chamber.

Headgear (Fig. 7) - is intended for installation and fastening of a driven pile on the Hammer. The headgear is attached to the Hammer with ropes through the eyes, which includes: body 1, shock absorber 2, eye 3, cable 4, clamp 5.

The principle of operation of the diesel tubular Hammer is as follows.

The Diesel Hammer operates automatically according to the scheme of a two-stroke engine (Fig. 8). when the piston rises, fresh air is pushed into the cylinder. When the piston moves down, part of the air leaves the cylinder until the piston closes the exhaust openings. The cylinder purge cycle ends. With further movement of the piston downward, air is compressed in the working cylinder. At the same time, the piston acts on the lever of the drive of the fuel pump, which delivers a certain amount of fuel to the combustion chamber located in the lower part of the cylinder above the scabbard. At the end of compression in the combustion chamber

the pressure and temperature rises sharply. Compression of air creates initial pressure on the pile, contributing to its immersion. When the piston hits the rampart, the pile is mostly submerged in the ground and at the same time it is sprayed and fuel begins to burn in the combustion chamber. The resulting gases sharply increase the pressure in the combustion chamber, tossing the piston up, and the pile receives an additional push down, increasing its immersion.

When the piston moves upward, the exhaust openings through which exhaust gases exit, and the purge cycle of the cylinder begins again. Having reached the top of the stroke, the piston again falls down repeating the cycle until the hammer is stopped.

The piston stroke height depends on the pile immersion upon impact and the amount of fuel supplied. With a large pile immersion at the beginning, the piston stroke is the smallest, therefore, if a pile that is too light is hammered into weak soil, then the Hammer may not start even after many starting attempts. In this case, a lighter Hammer model must be applied.

The disadvantages of the design of pile driving diesel tubular hammers include the lack of remote control of the hammer, where the operator needs to pull the rope tied to the lever of the fuel pump to stop the hammer in order to stop the fuel supply to the combustion chamber, which requires the constant presence of the operator-pile driver during hammer operation outside and in the rain, and in a snowstorm, and in

frost (up to -30 ° C), all this complicates its work, while the operator-operator controls the work of the Koprovaya installation from the tractor cabin, i.e. It is in a more comfortable environment.

The disadvantages of diesel tubular hammers include environmental pollution by combustion products during the operation of the hammer and the fact that at low ambient temperatures it is much more difficult to start the hammer, therefore operators have to raise the piston with the help of the Cat to the upper position up to 4-5 times , which reduces the overall performance of the Hammer.

In order to improve working conditions, eliminate environmental pollution and increase the productivity of pile-driving tubular hammers, where the energy of the falling body mass, such as a piston, is used to drive piles, we have developed a construction of a pile-driving tubular hammer with a diving, where a hydraulic cylinder is used to throw up - “dived” .

There are several types of hydraulic cylinder designs that are widely used in mechanical engineering (see Fig. 9):

but). double cylinder hydraulic cylinder,

b) .. hydraulic cylinder with one-sided rod,

at). differential hydraulic cylinder

d). hydraulic cylinder - "dived".

In our proposed design of a pile-driving pipe Hammer, we use the basic model of a pile-driving diesel

a tubular Hammer of type SP77A, where instead of a diesel drive for lifting the moving mass (piston) a plunger hydraulic cylinder is installed - it “dived”, which ensures that the piston rises upward with a stream of oil supplied from the hydraulic system of the pile plant under a pressure of about 12 MPa, “dived” under the upper the end face of the blind hole made in the Hammer piston (see figure 10 and figure 10 "a" and figure 11), which is in this case the novelty of the technical solution.

Here, the piston’s downward stroke, like that of the diesel tubular Hammer, is carried out by the free fall of the piston, since the lower hole “dived” in this case is connected to the tank and oil from the cavity of the blind piston hole is freely displaced into the tank, i.e. the principle of operation of both tubular Hammers is identical - the higher the cylinder body is raised, the greater the impact energy produced by the Hammer.

The device we offer piling pipe hammers with a diving is shown in figure 10 and figure 10 "a", which includes: a piston 1 with piston rings 2 and a retaining split ring 3, cylinder 4, shabot 5, lower bearing 6, upper bearing 7, guide pipe 8, eyelet 9, oil tank 10, shock absorber ring 11, shock absorber 12, holder 13, oil line 14, drain neck 15, lower grip 16, water tank 17, oil pump 18, oil line 19, dive 20 with elbow 21 floating on balls 22 mounted on the upper end of the flange 23 attached to rtsu sabotage with 7 screws 24, locking bolt 25, lower sensor 26, intermediate sensor 27,

upper sensor 28, mounting strap for sensors 29, mounting screw for strap 30, pin 31 rigidly fixed to piston 1, upper grip and lower grip 33, with which the Hammer is mounted movably on the Kopra SP49D guides, cover 34, which is installed during the transportation of the Hammer, ear 35 for transporting the Hammer, a guide sleeve 36 with O-rings 37 and cuffs 38, rigidly fixed in the lower part of the piston 1 with a locking screw 39 (Fig. 10 "a"), and a plate 40.

For remote control, this Hammer is equipped with four trackless proximity sensors (BTP) installed on the bar 29 and a portable Control Panel that provides Hammer control both from the tractor cab and on the street:

- “BTP-1” - piston low position sensor;

- "BTP-2" - sensor "Short stroke" of the piston;

- “BTP-3” - piston stroke “1200”;

- “BTP-4” - piston stroke “1500 stroke” sensor.

A portable control panel (not shown) on the front of which there are two three-position toggle switches “VK-1” and “VK-2”, as well as one button for activating a single blow.

The principle of operation of our proposed Hammer with a dive is as follows (see figure 10 and 11).

After a pile is installed in the hole of the Hammer’s headgear (Fig. 7) using a Copra (not shown), for example, the VK-1 toggle switch is turned on from the middle

(neutral) to the left position, corresponding to a piston stroke length of 1500 mm, while turning on the electromagnet "YA1" (see Fig. 11) of the P1 directional control valve and oil from the hydraulic system of the pile plant through pipeline 1 and through a flexible high-pressure hose 2 under a pressure of the order of 12 MPa is fed into the lower hole “diving”, as a result of which the piston 1 is lifted up until the plug 31 (Fig. 10), rigidly fixed in the piston body, is not compatible with the middle of the end face of the “BTP-4” sensor which will turn off the electromagnet "YA1" and turn on the electron nit “YA2”, hydraulic distributor “P1”, as a result of which the oil from the piston hole through the upper hole in the “dive” along the high pressure sleeve 2 will be displaced by the mass of the piston through the pipe 3 into the tank, providing a downward stroke until the plug 31 (Fig. 10) will not be compatible with the middle of the end face of the BTP-1 sensor, which, after hitting the lower end of the piston 1 in step 5, turns off the electromagnet YA2 and turns on the electromagnet YA1 of the P1 camshaft, resulting in oil under pressure 12 MPa from the hydraulic system of the pile driver through pipeline 1 the high-pressure sleeve 2 will again be fed through the “dive” hole under the upper end of the piston 1 hole, lifting up the piston body in the same sequence as described above until the VK-1 toggle switch is switched to the middle (neutral) position, after why the piston 1 will go down and when combining the plug 31 (figure 10) with the middle of the sensor "BTP-1" will turn off both

electromagnets and “YA2”, as a result of which the “P1” directional valve spool will occupy the middle position and cut off the oil supply from the hydraulic system of the pile plant, as well as block the drain cavity from the “dive” along the high pressure sleeve - the Hammer will stop in its lowest position.

When turning on the “short strokes” of the Hammer, performed with a high frequency and small amplitude of the order of 200 mm, necessary when driving piles in hard soils, the Hammer’s work is carried out in the same manner as described above, it is only necessary to turn on the VK-2 toggle switch from the middle (neutral) to the left position, in this case the BTP-1 and BTP-2 sensors will control the working “short strokes”, and to stop the Hammer, it is necessary to switch the VK-2 toggle switch to the middle (neutral) position.

To ensure the accuracy of driving piles at the same level (the difference in the upper ends of the driven piles should not exceed 10 mm), the “1 hit” button is installed on the Control Panel.

When the “1 hit” button is pressed, the “P1” hydraulic control valve solenoid “YA1” is turned on and oil from the hydraulic system of the pile driver is installed through the pipeline 1, along the high pressure flexible hose 2, at a pressure of 12 MPa, is fed into the lower hole “dived” and then under the upper end of the hole made in the Hammer piston, as a result of which the piston is lifted up until the “1 hit” button is pressed.

When the “1 hit” button is released, the “YA1” electromagnet is turned off and the “P1” directional valve solenoid “YA2” is turned on, as a result of which the oil from the piston hole through the upper hole in the “dive” along the high pressure sleeve 2 will be displaced by the piston mass through pipeline 3 into the tank, providing a piston stroke down until the plug 31 (Fig. 10) does not coincide with the middle of the end face of the BTP-1 sensor, which, after hitting the lower end of the piston 1 in step 5, turns off the YA2 electromagnet, but does not turn on electromagnet "YA1" due to lack of pressure on the "1 hit", which would result in stopping the Hammer. At the same time, the longer the “1 hit” button is pressed, the longer the stroke length is controlled by the BTP-4 sensor, which will not allow the piston to go beyond the stroke of 1500 mm and will automatically switch to the piston stroke down.

In case of failure of the operation of the upper sensor 28 (BTP-4) when the piston 1 is further raised upward, the snap split ring 3 falls into one of the grooves made in the upper part of the guide tube hole in the form of a “ruff”, which will cause the piston to stop 1. To lower the piston 1 down to its original position, it is necessary to turn the lever “VK-1” from the left position to the middle (neutral) position, piston 1 will go down, after which the cause of the failure of the BTP-1 sensor can be eliminated.

Other types of tubular hammers equipped with various types of power cylinders are also known (see

Fig. 9), in which the upward movement of the moving mass and the lowering down is carried out by the hydraulic system under high oil pressure (within 12 ... 24 MPa), i.e. during the down stroke, the free fall force of the moving mass of the Hammer is added to the force developed by the power hydraulic cylinder, which allows to reduce the length of the Hammer's stroke, while preserving the impact energy of the Hammer.

Consider the layout, hydraulic circuits and technical characteristics of several pile-driving tubular hammers, equipped with hydraulic drives that provide reciprocating motion of the moving mass of the Hammer (Table 1), close to the tubular hammer we designed with diving.

On Fig and Fig.13 shows the layout of the device and the hydraulic circuit of the modern domestic hydraulic tubular Hammer model MGZt with an impact weight of 3100 kg, developed and manufactured by Novosibirsk OJSC ROPAT, whose technical solutions are protected by domestic and foreign patents, and on technical In terms of its characteristics, this Hammer is in many ways superior to foreign samples of hydraulic tubular Hammers, where a hydraulic cylinder with a double-stem is used as a power drive.

In terms of their layout and principal hydraulic circuits, all hydraulic tubular hammers, both domestic and foreign, are very similar in structure and have the same hydraulic circuits, which are fully applied to

hydraulic rod hammers (see Fig. 14). as can be seen from the hydraulic circuit (Fig. 13), all hydraulic tubular and rod hammers are equipped with two hydraulic accumulators, which complicates the design of the hammers, and almost all hydraulic hammers for power hydraulic cylinders require the installation of separate hydraulic stations with corresponding components (electric motors, hydraulic pumps, hydraulic accumulators, control valves with control electromagnets, valves, hydraulic tanks, etc.), and for powering hydraulic motors with Power within 22 ... 55 kW, it is necessary m supply of power electric cables.

The operating procedure of hydraulic tubular and rod hammers from consideration of the hydraulic circuits of Fig. 11 and Fig. 13 is very close to the operating procedure of the tubular Hammer we developed with a diving (Fig. 10), described above and differs only in that if during the course of the moving mass of a conventional hydraulic Hammer up - oil from the hydraulic system under operating pressure is supplied to the lower cavity of the power hydraulic cylinder, and its upper cavity is connected to the tanks, when the moving mass of a conventional hydraulic hammer is down - oil under the working pressure is supplied to the upper cavity of the power hydraulic cylinder, and its lower cavity connects to the tanks, while the tubular Hammer with a diving visa moves through the free fall of the moving mass of the Hammer and expelling oil from the upper cavity of the opening of the movable piston through the hole diving into

tank, therefore, we do not give a more detailed principle of the operation of hydraulic tubular hammers.

Based on the foregoing, the following conclusions can be drawn.

- The disadvantages of tubular diesel hammers include: environmental pollution by combustion products during their operation, as well as their noise and inconvenience of hammer control due to lack of remote control.

When working in winter conditions, when the ambient temperature reaches a value of (-20 ° ...- 30 ° C), it is difficult for diesel hammers to start them, so you have to lift the Cat along with the moving mass (piston body) from its initial lower position dumping up to 4-5 times in order to start up the Hammer, which significantly reduces its productivity, as well as the low efficiency of the Diesel itself, as every 800 hours of its operation requires the replacement of piston rings.

- The advantages of tubular diesel hammers include their autonomy, which allows these hammers to work in areas remote from industrial facilities, as well as their relatively low cost.

- The disadvantages of hydraulic tubular hammers include: the complexity of the design of the hammer itself, the need to equip them with a separate hydroelectric station, the lack of autonomy (when the hammer is operated in conditions separate from

industrial facilities, an additional mobile power plant is required, equipped with an internal combustion engine and a generator to power the hydraulic motor), the high cost of these Hammers (the cost of a hydroelectric station is half the cost of the Hammer itself).

- The advantages of hydraulic tubular hammers include: environmental friendliness, remote control, quiet operation, reliability and performance.

Taking into account the fact that our company produces diesel diesel hammers of the SP77A model, which have the drawbacks described above, and in order to eliminate the above-mentioned drawbacks and improve their operating conditions (remote control has been introduced, the hammer is launched immediately by simply switching the toggle switch on the Control Panel), as well as reducing the cost of their manufacture (excluding the Cat node with its control system, excluding the node of the fuel supply and regulation system with a fuel pump, pipelines and tanks) We developed the original design of the tubular Hammer with a dive, while preserving the very principle of operation of this Hammer.

The principle of operation of a diesel tubular Hammer and a tubular Hammer with a dive is described in detail above, whence it follows that in the first case, the rolling mass is lifted upward by a flash of atomized fuel in the Diesel cylinder, and in our case, the rolling mass is lifted upward by a stream of oil supplied from the hydraulic system Pile rig, s

with a working pressure of about 12 MPa, it dived through the hole under the upper end of the piston, while the downward stroke of both Hammers is the free fall of the moving masses, and the higher the moving mass is raised, the greater the impact energy, therefore, as a PROTOTYPE for the tubular Hammer we developed with a dive, we accept the tubular diesel Hammer of model SP77A.

As a result of the modernization of the basic model of the diesel rod hammer SP77A, where a hydraulic drive of the "dive" type was installed in place of the diesel drive (piston with piston rings), powered by the hydraulic system of the SP49D pile driver (see figure 2, figure 10 and 11) , the following units are excluded from the basic model of a tubular diesel Hammer: “Cat” unit with a control mechanism, “Fuel supply” unit with a fuel pump, fuel supply control mechanism and fuel tank, which significantly reduces manufacturing costs of a tubular Hammer with a dive, and it does not require the installation of a separate hydraulic station to power the "diving" type hydraulic cylinder, and the operation of this Hammer will be environmentally friendly, less noisy and more convenient if there is a remote control from the portable Control Panel.

When conducting patent research of various designs of domestic and foreign samples of hydraulic tubular and rod hammers, the use of hydraulic cylinders as a drive was not found anywhere

type of "diving", therefore, our design of a tubular Hammer with a diving has a NEW TECHNICAL SOLUTION, while the device of this Hammer is simpler and more economical.

During the constructive study of the tubular hammer with the diving, we were able to increase the efficiency of the tubular hammer from 0.9 to 0.98 by reducing the number of friction surfaces between the mating surfaces of the piston rings with the cylinder of the hammer having a diesel drive, as well as the mating surfaces of the existing hydraulic hammers, having power hydraulic cylinders with double-sided rods (two rod mates and one piston mate with the hole of the hydraulic cylinder).
