Description

This utility model relates to the field of mechanical engineering: safety devices or devices for preventing injuries to people for welding.

The author knows the technology of welding with pipe laying on artificial prisms or inventory pads (source: “SP 34-112-97 Construction of main and field pipelines. Integrated technology and organization” section 6), which is presented in FIG. 1. Cases of using supports or factory-made supports for welding pipes are not known to the author. Often in the manufacture of welding and installation works use stands for handicraft production (Fig. 2, Fig. 3)

The technical disadvantages of these structures, which entail the risk of injuring people in the event of the pipe slipping off and falling off, according to the author, are:

- lack of a fixing element in the design of the stand;

- instability of the stand under the influence of gravity laid on them pipes, in case of improper installation on the surface;

- instability of the stand during accidental mechanical impact on the pipe from the outside (for example, by special equipment), as a result of the human factor (inattention and carelessness of the drivers).

The task to which the claimed utility model is directed is to exclude the possibility of capsizing or slipping of the pipe during welding, and subsequent injury to people.

An essential feature characterizing this utility model is the pyramidal design of the utility model with a self-jamming effect under the influence of the gravity of the pipe, as well as the displacement of the axis of the laid pipe closer to the center of the device, which increases the stability of the entire structure.

The problem is solved (the technical result is achieved) by performing the construction of the utility model in the form of a pyramid, preventing it from tipping over, and fixing the movable side forming structures on the hinges, ensuring self-jamming and fixing of the pipe under the action of its gravity, as well as by shifting the axis of the laid pipe closer to the center of the device.

A device for preventing injuries to people when welding pipes (hereinafter - UPTLS) is presented in FIG. 4 (front view - side view - top view). The main parts are: a frame of movable lateral generators 1 and frame 2 with hinges 3, providing free convergence-divergence of movable lateral generators 1, a movable lodgement 4 of two textile tapes with rubberized linings 5, which is suspended on articulated hinges 6. Hinges 6 in its the turn is put on on the side forming structures 1. The hinges 6 are made in such a way that they allow the pipe 12 (not part of the utility model) to lie on the lodgement 4 and take a free position at a small angle, the natural bending of the pipe 12. To ensure smooth self-jamming when lowering the pipe 12, and to prevent the backward divergence (collapse) of the movable side generators 1 when removing the pipe 12, spring shock absorbers limiters 7 are attached, which are attached to the frame 2. To move the UPTLS inoperative Two skis 8 with spring shock absorbers 9 and a drawbar 10 are provided. Considering that the welders have different heights, the spring shock absorbers 9 have several holes for adjusting the height of the UTLS with clamps 11. For pre to prevent horizontal displacement UPTLS in working condition, the lower ends of the spring shock absorbers 9 are made in the form of cones.

The principle of operation of the utility model is shown in FIG. 5 - FIG. 7:

UPTLS before lowering the pipe 12 is in the free position. At the same time, skis 8 are wrung out under the action of spring shock absorbers 9, UPTLS can be moved. The movable side generators 1 are pressed by spring shock absorbers-limiters 7, the lodgement 4 is in an arbitrary position (Fig. 5).

When lowering the pipe 12, the lodgement 4 wraps around it, and under the action of gravity, the pipe 12 rushes down to the center of the device, while the movable side generators 1 are pulled through the hinges 6, the pipe is fixed in UPTLS. Under the influence of the gravity of the pipe 12 UPTLS falls down, skis 8 wring out spring shock absorbers 9, while their pointed lower ends are plunged into the ground through the holes in the skis, the UPTLS is fixed from horizontal displacement (Fig. 6).

When removing the pipe 11, the load is removed from the lodgement 4, the movable side components 1 are moved apart by spring shock absorbers-limiters 7, which allows you to remove the pipe 12 without the participation of personnel. Spring shock absorbers 9 push the skis 8 down, UPTLS rises, and is ready to move in the horizontal direction to the next place of work or to withdraw from the work zone in general (Fig. 7).

The technical result is to provide stability UPTLS and the exclusion of injuries to people in the fall or slipping of the pipe during welding.

The essence of the utility model is illustrated by drawings, which depict:

FIG. 1 - photo of the general technology of welding;

FIG. 2, - stand for handicraft production;

FIG. 3 - the use of handicraft stands for welding;

FIG. 4 - a general view of the device for preventing injuries to people during welding (views - front; - side; - top).

FIG. 5 - the position of the structural parts UPTLS without load, inoperative.

FIG. 6 - the position of the structural parts UPTLS under load, in working condition.

FIG. 7 - the position of the structural parts UPTLS after unloading.

The introduction of a utility model into production will minimize the risk of injuring people as a result of a pipe fall, and reduce the overall statistics of accidents during welding and installation works.

The disadvantage of this utility model is the relative bulkiness of the design.
