Description

The utility model relates to auxiliary devices for welding.

A trolley for working under a car is known from the prior art (patent RU 2135346 C1, published on August 27, 1999), containing a bed with wheels and a headrest, the rods of which are connected to the bed with the possibility of rotation around an axis installed below the plane of the bed, while the headrest is equipped with a bracket, mounted between the bars of the headrest with the possibility of rotation around a horizontal axis and having a support element in contact with the support section of the bed, while the size of the support element of the bracket in terms of its minimum internal size in the direction of the axes of rotation exceeds the maximum width of the support section of the bed, the sum of the distances from the horizontal axis of rotation of the bracket to the axis of rotation of the headrest bars and from the horizontal axis of rotation of the bracket to the upper edge of its supporting element exceeds the distance from the axis of rotation of the bars of the headrest to the upper edge of the support section of the bed, and the horizontal projection of the horizontal axis of rotation of the bracket onto the plane of the bed is located on the support section of the bed.

The closest technical solution is a wooden welder's chair (patent US 10029362 B2, application US 20170014991 WELDING WOOD CREEPER RECLINER), containing a frame, rear support and seat made of wood. The rear supporting part has a lifting mechanism, and the frame is equipped with roller wheels.

The chair has a working position "sitting" with the possibility of adjusting the rear support part to change the position of the welder's back, while the welder's legs remain bent and rest on the work surface (floor). In addition, the chair is equipped with roller wheels that can move on a hard, level work surface. This chair does not have the functionality to work in the “lying” or “reclining” position, when the legs are extended, for example, for welding work, for example, under a pipeline or on some other structures, the welded surfaces of which are horizontal, and welding work is possible only in working position "lying" or "reclining" with legs stretched forward. Also considering that the construction, repair of the pipeline, as well as other structures are carried out on the ground (soil), the surface of which is naturally extremely uneven (embankment, trench), it is impossible to move the roller wheels along such a working surface.

The technical problem follows from the fact that welding work on pipelines and many other structures is carried out outdoors in the field in the harsh climatic conditions of the North, Siberia, the Far East under different weather conditions, and welding is a long, high-precision, labor-intensive technological process performed by a welder as both standing and sitting/half-sitting/reclining/lying positions, so it is important to provide a comfortable, adjustable support for the welder.

The technical result consists in the creation of a transformable welding bed that provides support for the welder during welding and protects him from direct contact with the working support surface, for example, the ground covered with snow, mud, etc. The technical result provides a transformable welding bed, containing three sections connected in series with each other by fasteners, each section is made in the form of a frame with a non-removable base fixed to it, and folding legs are fixed on each frame, made with the possibility of changing their height, rotary combs and stoppers installed with the possibility of fixing the position of each section of the lounger.

Fasteners can be hinges, metal loops, loops.

The frame can be made of a bent metal pipe, or from pieces of metal pipes welded or bolted together, or from wooden or composite bars, bolted, metal or wooden nails, glued or thermally soldered together.

The non-removable base can be made in one piece. The non-removable base may be composite. Folding legs can be telescopic.

The proposed device is illustrated by drawings.

The proposed transformable welding bench (figure 1-6, hereinafter referred to as the lounger) contains three sections 1, connected in series with fasteners 2 (figure 2), providing the possibility of transformation, i.e. folding one section 1 onto another and unfolding. The fasteners 2 can be hinges, metal loops, belt loops made of a fire-resistant/fire-resistant material, for example, based on mineral or carbon fibers, tarpaulin or belting. Each section 1 is made in the form of a frame (frame) 3 with a non-removable base 4. The frame 3 can be made of a curved metal pipe of any section, or from segments of metal pipes of any section, welded or bolted, from wooden or composite bars of any section, fastened with bolts, metal or wooden nails, glued or thermally soldered together, depending on what material the frame 3 is made of, while all wooden elements must be treated with a refractory / fire retardant agent, for example, fire retardant resin or coated with a refractory / fire retardant material, such as flame retardant felt. Fixed base 4 is fixed on the frame 3, for example, by welding or bolting. The fixed base 4 can be made in one piece (Fig. 1c), for example, in the form of a metal, composite or wooden plate coated with a refractory / fire-resistant material, or composite (Fig. 1a, 1b), for example, in the form of a metal, composite or wooden lattice lined with refractory/flame retardant material. The refractory/fire-resistant material can be, for example, fire-resistant felt, which ensures the fire safety of the inventive lounger. Additionally, section 1 can be equipped with folding legs 5, fixed on the frame 3 by a bolted connection 6 with two fixing nuts (not shown), and the legs 5 themselves can be telescopic, which together provides the possibility of transformation (folding/unfolding). In addition, section 1 can be provided with a rotary comb 7 and a stopper 8 fixed on the frame 3 to fix the section 1 in the required position.

Additionally, a fixing lock (not shown in Fig.) is installed on the frame 3, which secures section 1 in the folded state, and a handle 9 is fixed to enable the proposed lounger to be transferred/transported. The locking lock may be in the form of a tab with a protruding latch, or a swivel comb with a latch, or a cap lock, or other known locking fasteners. Depending on the material of the frame 3, the handle 9 can be attached releasably, for example by bolting, or permanently, for example, by welding, glued, thermally soldered or stapled.

Additionally, portable grounding elements (not shown in the figure) can be installed on the frame 3 to ensure electrical safety.

The proposed device is used as follows.

The proposed transformable welding bed is installed at the place of welding, in the initial state it is complex. Depending on the welding work performed, the working space, the location of the surfaces to be welded and the preferred position of the welder, the proposed lounger can be installed in the working positions of “lying”, “reclining”, “half-sitting”, “sitting”.

In the working position "lying" (Fig. 1a-c), three sections 1, made in the form of a frame 3 with a fixed base 4, connected in series by fasteners 2, are laid out horizontally on the working support surface (not indicated), then laid out and put on one the height of all legs 5, fixed on the frame 3 with a bolted connection 6 with two locking nuts (not shown), and the sections 1 are fixed with rotary combs 7 on the stoppers 8, but if necessary, all the legs 5 can remain folded (parallel to the frame 3), i.e. . the transformable welding bed is located horizontally directly on the working surface (on the ground or on the floor). The welder (not shown) is placed on a horizontally declared lounger, while all parts of his body are located on bases 4, fixed on frames 3 of sections 1, which are located horizontally at the same level, which protects (prevents) the welder from direct contact with the working support surface, for example, earth (soil), snow, mud, etc. and, as a result, improves the working conditions of a welder in harsh climatic conditions, reduces the risk of developing colds and occupational diseases. At the end of welding, the welder gets up from the bed, fold the legs 5 parallel to the frame 3, then fold sections 1 connected by fasteners 2, one on top of the other until the size of one section 1 is obtained (Fig. 6), fixed with locking locks (Fig. 1- 6 not shown) and, taking the handle 9, carry / transport the sunbed.

In the working position "reclining" (Fig. 3) three sections 1, made in the form of a frame 3 with a non-removable base 4, connected in series by fasteners 2, are laid out horizontally on the working support surface (not indicated). The legs 5, fixed on the frame 3 with a bolted 6 connection with two fixing nuts (not shown), are laid out, installed on a working support surface, for example, on the ground or on the floor, while in one section 1 the legs 5, made telescopic, are extended to a larger height than that of the other two sections 1, and fixed with rotary combs 7 on the stoppers 8. This allows you to obliquely raise one section 1 relative to the other two, forming a supporting back. The welder (not shown) is placed on the inventive reclining lounger, while his back rests on the base 4 of the frame 3 of the obliquely raised section 1, and the pelvis and legs are on the bases 4 of the frame 3 of the other two sections 1, which are located horizontally at the same level, which allows for the welder to take a comfortable position on the support for work, for example, when welding inclined surfaces, protects (prevents) him from direct contact with the working support surface, for example, cold earth, snow, dirt, etc. and, as a result, increases the period of welding without fatigue, improves the working conditions of the welder in harsh climatic conditions, reduces the risk of developing colds and occupational diseases. At the end of welding, the welder gets up from the bed, remove the fixing rotary combs 7, fold the legs 5 parallel to the frame 3, then fold the sections 1 connected by fasteners 2, one on top of the other until the size of one section 1 is obtained (Fig. 6), fix with locking locks (not shown in Fig. 1-6) and, taking the handle 9, transfer / transport the sunbed.

In the working position "half-sitting" (Fig. 4) three sections 1, made in the form of a frame 3 with a non-removable base 4, connected in series by fasteners 2, are laid out horizontally on the working support surface (not indicated). The legs 5, fixed on the frame 3 with a bolted 6 connection with two fixing nuts (not shown), are laid out, installed on a working support surface, for example, on the ground or on the floor, while in one section 1 the legs 5, made telescopic, are extended to a larger height, in the middle section 1, the legs 5 are set at the height of their own size, and in the third section 1, the legs 5 remain folded parallel to the frame 3, the sections 1 are fixed with rotary combs 7 on the stoppers 8. This allows you to tilt one section 1, horizontally position the middle section 1 and obliquely lower the third section 1. The welder sits on the inventive lounger, while he leans with his back on the base 4 of the frame 3 of the obliquely raised section 1, the pelvis and legs to the knees are on the base 4 of the frame 3 of the middle section 1, which is located horizontally, and the legs are lower knees are located on the base 4 of the frame 3 of the obliquely lowered section 1 (i.e. the legs do not rest on the ground or floor), which allows the welder to take on a support a comfortable position for work, for example, when welding inclined surfaces, protects (prevents) it from direct contact with the working support surface, for example, cold earth, snow, mud, etc. and, as a result, increases the period of welding without fatigue, improves the working conditions of the welder in harsh climatic conditions, reduces the risk of developing colds and occupational diseases. At the end of welding, the welder gets up from the bed, remove the fixing rotary combs 7, fold the legs 5 parallel to the frame 3, then fold the sections 1 connected by fasteners 2, one on top of the other until the size of one section 1 is obtained (Fig. 6), fix with locking locks (not shown in Fig. 1-6) and, taking the handle 9, transfer / transport the sunbed.

In the working position "sitting" (Fig. 5), three sections 1, made in the form of a frame 3 with a fixed base 4, connected in series by fasteners 2, are stacked one on top of the other to the size of one section 1. The legs 5 of one (extreme) section 1 are laid out so that they have the same height, and are fixed with rotary combs 7, forming a "stool" on four support legs 5, which is installed on a working support surface, for example, on the ground or on the floor. A welder (not shown) sits on the base 4 of frame 3 of section 1 as a “stool” (legs rest on the ground or floor), which allows the welder to take a comfortable position on the support for work, for example, when the working space is significantly limited or welding work is performed on vertical surfaces, protects (prevents) it from direct contact with the working supporting surface, for example, cold earth, snow, mud, etc. and, as a result, increases the period of welding without fatigue, improves the working conditions of the welder in harsh climatic conditions, reduces the risk of developing colds and occupational diseases. At the end of welding, the welder gets up from the bed, remove the locking rotary combs 7, fold the legs 5 parallel to the frame 3, get the folded bed to the size of one section 1 (Fig. 6), fix it with locking locks (not shown in Fig. 1-6) and , taking the handle 10, carry / transport the sunbed.

If necessary, other versions of the base 4 can be made, other transformations of sections 1 connected by fasteners 2, and legs 5 can be made to provide support for the welder during welding and protect him from contact with cold ground, snow, dirt, etc.

That. The proposed welding bench can be made of different materials, has different design options and transformations to provide a comfortable support for the welder during welding and protects (prevents) him from direct contact with the working support surface, for example, the ground covered with snow, dirt, etc. .p., easy to maintain and transport.
