Description

Known invention "Safety belt", No. RU 2027451, IPC class A62B 35/00, published 01/27/1995. Usage: safety devices that ensure the safety of work at heights. The inventive device contains a belt with a buckle, a sling with a carabiner, piercing shock absorber, laid with the formation of corrugations, rings to accommodate the belt and shock absorber, and the sling is connected to the loop. Disadvantage: it cannot be applied, because It has no elements for connecting a pneumatic chipping hammer to the belt.

The invention is known "Waist belt for unloading muscles", RU 2041685 C1, IPC class A45F 3/14, published on 08/20/1995. The inventive waist belt for unloading muscles contains a waist belt 1, at the opposite ends of which there are elements 2, interacting with each other and providing regulation of the length of the waist belt, and at least one pad 3 attached to the waistband 1. The pad 3 is provided with a base 5 , frame and pockets 14 and 15 mounted on the frame. The base 5 is located on the pad 3 along its length and is fixed on it with one end using a swivel 6, and the other with a detachable element 7. The frame is made of elements interconnected by a movable link, and is fixed on the base with the possibility of sliding it in the direction perpendicular to the base, and fixation. The pocket 14, mounted in the Central part of the frame, is mounted on it with the possibility of rotation relative to the axis of attachment and is made of elastic material. The pad 3 is attached to the waist belt 1 with the ability to move along its length. Disadvantage: it also does not have elements for connecting a pneumatic chipping hammer, so it cannot be used.

The invention is known “A device for cutting sheet material to a pneumatic hammer", RU No. 2057632 C1, IPC B25D 9/04, published on 04/10/1996, authors Volkov G.Yu., Krokhmalev NN, Spector Y.D. The inventive device is intended for use in conjunction with a pneumatic hammer having a floating handle. It contains a movable knife, interacting with the hammer of the hammer, and a bracket with a fixed knife, rigidly connected to the hammer body through an intermediate sleeve having a threaded connection with both the body and the bracket. The bushing simultaneously serves as a support for the shock absorber of the movable knife when idling. The bracket has a guide rod parallel to the axis of the housing, which interacts with a guide sleeve mounted on the floating handle of the hammer. The design ensures the correct angular position of the bracket relative to the handle, regardless of the relative position of the body and the bracket, which changes when adjusting the free movement of the movable knife and the initial position of the movable and fixed knives. A spring is put on the guide rod to axially tighten the bracket to the handle, which, together with the spring contained in the hammer, squeezing the housing from the handle, provides an equilibrium axial position of the handle, i.e. its anti-vibration suspension. To lock the threaded connections of the intermediate sleeve with the body and bracket, the sleeve consists of two halves, tightened together by bolts. The disadvantage is that the bracket cannot be connected to the belt.

The prototype selected the invention "Machine for chipping, riveting, ramming", RU 2412783 C1, IPC B22D 31/00, published on 02.27.2011, Bull. No. 6, author Bondarev V.N. The machine consists of: a two-section console, a chipping device with a chipping head, a mechanism for holding the chipping device in suspension in space, a mechanism for holding the chipping head in suspension, a fixing system for the console with a chipping device, and a pneumatic or pneumatic hydraulic system of the chipping head. The chipping device has a machine pneumatic hammer, which is pivotally connected with its rear end to the crank. The pneumatic hammer has a thread or grooves at the front end of the barrel with which a quick-detachable sleeve 57 (Fig. 8, 9, 10) is connected to the pneumatic hammer or with the teeth of the sleeve, and the sleeve has one or two chisels 58 (Fig. 8) 37 directed along the axis of the chisel and having at its end on the inner side each one or two hooks 60 (Fig. 8), and each rule also has two side turn signals 61 (Fig. 8, 9) on the inside, between which it can fit with sliding stabilizer 62 (Fig. 8, 9) of the chisel. The machine pneumatic hammer has a chisel with one or two bosses 63 (Fig. 8, 10) on one side of the chisel or on two opposite sides of the chisel, inextricably connected to the chisel (by welding with heating or hot upsetting). The stabilizer is also inextricably connected to the chisel. The chisel has a longitudinal movement within the clearance "g". Thus, unauthorized removal of the chisel from the pneumatic hammer during idle operation of the pneumatic hammer is prevented by stopping the boss 60, which is fixedly connected to the chisel, in the hook 60, which is fixedly connected to the rule, which is connected to the barrel of the pneumatic hammer. Disadvantage: this machine is bulky, has a high cost, requires an additional flow of compressed air to fix the console in space and has not yet been used.

The aim of the invention is to simplify and cheapen the design, unloading the muscles of the hands and shoulders of the user from the pressing force of the pneumatic hammer (pneumatic hammer) to the product and from the weight of the pneumatic hammer, reducing the negative impact of vibration on the user, reducing labor costs, reducing the severity of work, increasing labor productivity.

These and other goals are achieved by the fact that the user performs the most difficult work of pressing the pneumatic hammer not with his hand, but with his trunk, or axillary region, with vertical cutting from top to bottom, for which the equipment has an equipment frame fixed to the user's shoulder joints and has the lower part of the equipment belt, and the crank is articulated to one end by a crank, to the opposite end of which a pneumatic hammer rod is connected using the ball pair or telescopically, to the opposite the end of which is connected to a pneumatic hammer. Thus, when the user presses the housing, the force is transmitted to the frame, to the crank, to the hammer rod, to the hammer, to the chisel and to the product, bypassing the arm and elbow joint. This option is easier for the user, in addition, the torso can be pressed with more force than with the hand, and therefore the cutting speed increases and, therefore, productivity increases. In addition, the pneumatic hammer is suspended from a mini-console attached to the belt, and the pneumatic hammer is suspended, and the operator does not expend energy on holding the pneumatic hammer on weight, and both user hands are protected from vibration, preventing vibration.

Equipment has the following assembly units interacting with each other: a) a frame having a front part of the frame and a rear part of the frame, b) a pneumatic chipping hammer (pneumatic hammer) or an electric chipping hammer (with a working tool, such as a chisel or riveting mandrel), c) a crank connecting the pneumatic hammer with the frame, d) the equipment may have a mini-console fixedly connected to the rear of the frame and having a flexible rope connecting the mini-console with the pneumatic hammer.

The figure 1 shows the equipment together with the user, where the frame is indicated by 1, the pneumatic hammer - by 2, the crank - by 3.

The frame placed on the user's body consists of two parts - a rigid front part 4 of the frame, FIG. 3, and the rigid rear part 5 of the belt, FIG. 3, which are hinged, with a vertical axis of rotation, connected to each other by a hinge 6, FIG. 3, with the ability to occupy various fixed positions relative to each other in accordance with the dimensions of the body of the operator.

The front part of the frame at the top has two rigid tool holders 7, FIG. 1 located in the axillary parts of the user's body. They are fixed on the user's body with elastic belts 8, FIG. 1, with fasteners 9, FIG. 1. The front of the frame below has a rigid front 10, FIG. 1, belt. The front of the frame has struts 22, FIG. 1, to which the lodgements 7 are fixedly connected with the ability to occupy various fixed height positions on the uprights in accordance with the dimensions of the user's body using bolted joints, pos. 23 of FIG. 2. The frame has a screed 24, FIG. 2 connecting two lodges. Under the axillary part of the body, the operator can act on the lodgement with a force directed downward, or to the right, or to the left, or forward, or backward. Elastic belts 8 prevent arbitrary lowering of the frame down.

The back of the frame may have (at the request of the user) a mini-console 11, FIG. 1, with a balancer (not shown in FIG.) Or with one or two blocks 12, FIG. 1, 2, in the streams of which a rope 13 is placed, FIG. 1, 2. The rope is placed in the streams of the blocks and is connected at one end to one end of the spring 14, FIG. 2, stretching, which at its opposite end is connected to the rear part 5 of the belt and acts on the rope with force. The opposite end of the rope is connected to the rod 40, FIG. 1, a pneumatic hammer 2 and acts on it with force. Figure 1 shows a variant of the mini-console with one block, and figure 2 shows a variant with two blocks.

The front part of the frame has an upper right support plate 15, FIG. 1 adjacent to the right side of the user's chest has a left support plate 16, FIG. 3 adjacent on the back to the user's left shoulder blade and has a lower right support plate 17, FIG. 1 adjacent to the upper right thigh of the user. The back of the frame below has a lower left support plate 71, FIG. 2 adjacent to the user's left buttock. All base plates, as well as tool holders and hard parts of the equipment belt, have soft pads on the side of contact with the user's body. Pads can be made, for example, of felt or rubber. The front and back of the belt have vertical cuts 18, FIG. 2, allowing to bend parts of the equipment belt in accordance with the individual body shapes of the user.

To the front part 4 of the belt is fixedly connected, for example, by means of rivets, with one end of its elastic belt 19, FIG. 1, 2, with buckle 20, FIG. 2.

To the rear part 4 of the belt the elastic belt 21 is fixedly connected at its one end, FIG. 3, having openings for connecting it to the buckle 20, FIG. 3. The front of the belt 10, the rear of the belt 5, the elastic belt 19, the elastic belt 21, connected by a buckle 20 in accordance with the size of the user, make up the equipment belt, which is fastened not tight, but with the ability to occupy various fixed positions in the user's waist with the position of the user's shoulders relative to the lower back when tilting the body or turning the shoulders. The hard parts of the equipment belt have soft pads to protect the wearer's body from vibration, and the equipment belt is located at the level of the user's trouser belt.

Connected to the frame rack with the ability to occupy various fixed positions in height by means of a bolted connection 25, FIG. 2, crank 3, FIG. 2, consisting of a pusher 26, FIG. 2, and sectors 27, FIG. 2 having teeth 28, FIG. 2, and troughs. The sector is fixedly connected to the strut 22. The pusher is pivotally connected at one end to the sector using the axis 29, FIG. 3, and has an incomplete rotation around this axis. A lever 30 is pivotally connected to the pusher, FIG. 2, 3 having a tooth 91, FIG. 3, which can fit in troughs, and a tension spring 31 is connected to the lever at one end, FIG. 3, connected at its opposite end to the axis 29 and acting on it with force, and thus the tooth is in the cavity, and the pusher has a certain fixed position when cutting. To change the position of the pusher relative to the sector, press the lever 30 with a hand, rotate the pusher to the required angle, release the lever, thereby fixing the crank in another specific position, and cut at a different point on the product.

An external link 40 is connected to the opposite (distant) end of the pusher 26 telescopically or using a spherical pair, FIG. 1, a pneumatic hammer, or internal thrust 41, FIG. 10, a pneumatic hammer, or one of three vibration-proof elements in order to protect the user's body from vibration.

To the opposite (far) end of the pusher, a vibration-proof element in the form of a coiled coil spring 32 can be fixedly connected, FIG. 3, or in the form of a leaf spring 86, FIG. 9, or in the form of a torsion spring 37, FIG. eleven.

In the case of connecting a vibration-proof element in the form of a leaf spring, one of its ends is fixedly connected to the pusher by a bolt 85, FIG. 9, and the opposite end of the leaf spring is fixedly connected to the housing 34, FIG. 10, a ball pair with a bolt 87, FIG. 10 and the lock washer 88. A screw 35 may be used to create the initial spring force, FIG. 9 mounted on the end of the bracket 36, FIG. 9, which at one end is fixedly connected to the push rod. In FIG. 10 the longitudinal axis 66 of the ball pair, in order to expand the possibility of rotation of the pneumatic hammer at an angle β, FIG. 10, is located at a certain angle to the longitudinal axis of the pneumatic hammer.

In the case of connecting to the end of the pusher a vibration-proof element in the form of a torsion spring 37, FIG. 11, one end of the torsion spring is fixedly connected to the end of the pusher 26, FIG. 12 using a bolt 38, FIG. 12 and pads 39, FIG. 12. The second end of the torsion spring is threaded into the threaded sleeve 42, FIG. 12, with an external thread and welded to a threaded sleeve onto which an outer rod 40 is rotated around one end of the thread and rotated about a horizontal axis 43, FIG. 12, to a full angle of 360 degrees in order to be able to disconnect the external link from the vibration protection device if necessary.

If there is already a vibration protection element connected to the vibration protection element, the outer rod 40 is connected telescopically (FIGS. 11, 12) or with the help of a ball pair (FIG. 10), FIG. 11, 12, or internal draft 41, FIG. 10, a pneumatic hammer, which at its opposite end is fixedly connected to the sleeve 44, FIG. 2, 7. On the outer surface of the sleeve 44 there is a helical groove with a step equal to the winding pitch of a conventional coil spring 46, FIG. 4, or a baleful twisted spring. One end of a cylindrical twisted tension spring 46 is screwed onto the sleeve 44 with an interference fit in the groove; FIG. 3, 4, the end of the wire of which is fixedly fixed on the sleeve 44 by means of a cracker 47, FIG. 3, 4, or welding. Spring 46 works in tension. The opposite end of the tension spring 46 is screwed onto the housing 48 with an interference fit, FIG. 3, 4, a pneumatic hammer 2, and this end of the spring wire is fixedly fixed to the housing of the pneumatic hammer using a cracker 49, FIG. 4, or welding. Between the inner diameter of the sleeve 44 and the outer diameter of the barrel 50, FIG. 4, the pneumatic hammer has a gap for the outlet of the exhaust compressed air and to prevent the transmission of the barrel vibrations of the pneumatic hammer to the sleeve 44. The spring 46 serves to prevent the transmission of the pneumatic hammer vibrations to the rod 40 or 41 and further to the handle and the user's right hand. The longitudinal axis of the pneumatic hammer, which is in the initial position, passes through the vertical axis of the user body (figure 3). Springing of the spring 46 is done, if necessary, so that the spring begins to act with a certain initial spring force Pnach.

A handle 51 is fixedly connected to the opposite end of the rod or to the sleeve 44, FIG. 3, with a starting device and with a trigger 52, FIG. 3, which is pressed by the user to start the compressed air. The starter 51 is connected by a flexible sleeve 53, FIG. 4, with a pneumatic hammer housing, and compressed air flows inside the sleeve. The flexible sleeve also prevents the spread of vibration from the pneumatic hammer to the handle.

In order to prevent premature touching of the handle with the workpiece 54, FIG. 1, or rack 55, FIG. 1, brush 56, FIG. 4, directed horizontally.

Work tool 58, FIG. 1, 3, can be inserted into the barrel pneumatic hammer in the traditional way, i.e. without fixing in the longitudinal direction (not shown in the figures), or with fixing. The fixation is carried out by elastic tape 59, FIG. 3, with a memory of length having a cross-section in the shape of a rectangle. The tape performs several functions: it fixes the tool in the longitudinal direction, and when exposed to it by hand, it makes it possible to turn the tool around the longitudinal axis of the pneumatic hammer directly during the cutting process or during readjustments, and also prevents unauthorized removal (popping up) of the tool from the pneumatic hammer barrel during idle pneumatic hammer. To this end, the hook 60 is fixedly connected to the tool 58 by a permanent connection (by welding with preheating and slow cooling), FIG. 4 and FIG. 6 having a leg 61; FIG. 4, 6, arc 62 with stops 63, FIG. 6.

In order to freely rotate the tool around its longitudinal axis, there is a drum 64 on the barrel 50 of the pneumatic hammer, FIG. 4 having a ring 65, FIG. 7, having a rotation around the longitudinal axis of the pneumatic hammer, but its movement along the axis of the pneumatic hammer is limited. To the ring 65 is fixedly connected using the drum legs 67, FIG. 4, arc 68, FIG. 5, with stops 69, FIG. 5. Ring 65 has a diffuser 70, FIG. 7, with a window (not shown in the figures) releasing the exhaust compressed air away from the upper respiratory tract of the user in order to reduce the likelihood of silicosis. The drum and the hook are connected by an elastic tape 59 with a memory length with a slight tension of the tape, located in several places on both arcs. The elastic tape acts on the drum and the hook with force, which prevents unauthorized removal of the tool from the barrel of the pneumatic hammer, for example, during "idle" operation of the pneumatic hammer. Figure 4 shows a variant where the tape bends around the drum arc in three places, and the hook arc 60 bends around in two places, i.e. option "3 + 2", but there may be options "4 + 3", "2 + 3". In FIG. 7 shows the “2 + 3” variant, where the arc 68 envelopes the tape in two places, and the arc 60 envelopes in three places.

To replace the tool, remove the tape, remove the tool, insert another tool that has a hook, and lay the tape in arcs with a slight tightness. During operation, the user holds his hand in sections of the tape without touching the vibrating tool, which reduces the likelihood of vibro-illness. In addition, in many cases, the need to hold the tape with your left hand disappears, because the pneumatic hammer together with the chisel are stably in a certain position, determined by the position of the user's right hand and the end of the rod 40 (that is, a straight line is defined by two points).

In the case of using the internal link 41, it is located between the tool 58, FIG. 14, and the tape 59 (with gaps between the tool and the tape and internal traction). In FIG. 14 is indicated by double dash-dotted lines the extreme position of the rotated tool when cutting on a horizontal surface. Similarly (not shown in the figures), the internal thrust is located between the ring 65, FIG. 7, and a tape 59 enveloping the arc 68, FIG. 5.

Figure 13 shows an application of a tool (e.g., a chisel) that is not fixed along the longitudinal axis, in which a vibration protection device having one or more rings 73 is used to reduce the harmful effects of low-frequency vibrations, Fig. 13 made of metal rope 74, FIG. 13, twisted of thin wires, and the rope can be placed in a soft, for example rubber, tube 72, FIG. 8, to reduce the effects of vibration. To attach the rope to the chisel to the last fixedly inseparable connection, a block 75 is connected, FIG. 13, by welding with preheating and subsequent slow cooling. The block has a longitudinal hole with a thread at the beginning of the hole and has two or more transverse holes into which the rope is threaded. Inserts 76 are inserted between the rings of the rope inside the longitudinal hole, FIG. 13, which when the bolt 77 is rotated, FIG. 13, compress adjacent rings and fix them. The bolt 77 is fixed to prevent inversion by the lock washer 78, FIG. 13. Such a tool can be reforged when its cutting part has worked, for which the lock washer 78 is bent, the bolt 77 is turned out, the rubber tubes are removed one by one, the rope 74 and inserts 76 are removed, the tool is heated, reforged, hardened, the tool is grind and the vibration-proof device is assembled again .

In order to expand the possibilities of processing products, a height-adjustable shelf 55 is used, FIG. 1, in which, for example, the pin is inserted into the hole 79, FIG. 1, in accordance with the height at which processing with the use of equipment is most convenient, or a grid 80 is placed under the feet on the floor, FIG. one.

In FIG. 10 shows an embodiment of connecting a pneumatic hammer to an equipment belt using a ball pair, which in the simplest case consists of a ring 81, FIG. 10 worn on ball 82, FIG. 10, and the ring is fixed with the possibility of rotation around three mutually perpendicular axes with a nut 83, which is locked from unscrewing by a pin 84.

The length of the crank and the point of its attachment to the equipment belt using the axis 29 are chosen so that the tape is in the reach zone with the left hand of the user, and the handle is in the reach zone with the right hand of the user at any operating positions of the pneumatic hammer.

The housing 48 of the pneumatic hammer has a cap 89, FIG. 4, with the size of a wrench needed to screw the housing onto the barrel 50 of the pneumatic hammer, and also the housing has a nipple 89, FIG. 4, with a brush for connecting the flexible sleeve 53.

To the equipment belt, an electric chipping hammer (not shown in the figures) can also be adapted for operation.

Functioning equipment.

First, put on the frame 1 with a belt, then set the pusher 26 at the necessary angle to the horizontal with the help of the lever 30, having a tooth included in one of the depressions of the sector 27, then bring the end of the tool 58 to the cutting site on the processed casting 54, providing physical contact, press on the trigger 52 and produce the process of cutting, or riveting, or ramming. At the same time, with the right hand and his body, the operator is able to change the direction of the cutting, rotate the chisel around its longitudinal axis and, therefore, process complex curved surfaces that are variously located in space. In the case of operation, the pneumatic hammer in the initial position is pressed against the body of the operator, mainly the front part of the belt and the left side member. In the case of pulling the handle of the pneumatic hammer closer to the right side of the user, the reaction force from the product can create a torque relative to the user’s body, clockwise relative to the user’s body (see figure 3). In this case, the front section of the belt, as well as the support plates, act with force on the operator’s case.

If the cabin is driven from top to bottom, then the operator’s body is affected by a force directed from bottom to top, mainly through the left tool tray. When cutting on a plane, and not on a screw surface, the operator does not need to contact the chisel or tape with his left hand, since the chisel blade maintains the position defined by the surface being machined, which further reduces the likelihood of vibro-illness. Note that in the traditional method, the operator is forced to contact the vibrating chisel with his left hand, otherwise the chisel blade will move away from the place of cutting and the cutting process will stop. At the end of the chopping process, the operator returns the trigger to its original position, and the chopping process is stopped, the operator stops making the effort of pressing the pneumatic hammer to the product. If the operator did not have time to turn off the compressed air in time and the pneumatic hammer continues to work “idle”, then the tape keeps the tool from falling out of the pneumatic hammer or the operator holds the tool, holding the rings 72 with his left hand. If the next processed section of the product is, for example, higher than the processed section, the operator removes the tooth of the lever from the cavity, puts the tooth in another cavity located above the previous one. To process the product from all sides, the operator can first process four vertical sides of the product, then rotate the product 90 degrees around the horizontal axis and process the fifth and sixth surfaces.

The positive experience of working with a pneumatic hammer with a chisel having a hook 37 and having a rubber tape with a rectangular cross section laid on the back of the housing of the pneumatic hammer was carried out. The tape was obtained by cutting a ring 25 mm wide from a large diameter rubber car camera. Experience has shown that during operation, the pneumatic hammer “idles” the chisel makes reciprocating movements along its longitudinal axis, but remains in the pneumatic hammer after it stops working, and you can start work again, and blows to the left hand from the side of the tape are not felt.

The following results have been achieved:

1. The operator’s hands are unloaded from the force of the weight of the pneumatic hammer and the amount of muscle energy is reduced while holding the pneumatic hammer in weight.

2. The arms, shoulders and partly the upper body are unloaded while creating efforts to press the pneumatic hammer to the product.

3. It is possible to control the chisel during the cutting process by turning the chisel around its longitudinal axis and around the axes of the ball pair and, therefore, process complex curved surfaces in one step (in one chopping cycle).

4. Reduced the likelihood of vibration diseases due to the use of vibration-protected handles for the right hand, the use of elastic tape for the left hand, the use of soft pads in the belt, the use of vibration-protective elements in the crank and the use of a spring on the air hammer body.
