Description

I

The invention relates to devices for transport operations and can be 1: in construction, mechanical engineering for the transport of gas cylinders from the storage site to the area of gas cutting and welding at construction sites. In machine-building workshops, stretchers are used, with the aid of which gas balloons are transferred in horizontal or inclined position manually.

The closest to the invention to the technical essence and the achieved result are A stretcher for gas cylinders in the form of a pair of half-mowers containing grippers and levers with handles 1.

A disadvantage of the prior art construction is the low level of security and the inconvenience of their use.

Objective 1 of the invention is to increase the safety and comfort of the stretcher at work.

The goal is achieved by the fact that the claws are made in the form of a ring, and the levers are provided with plates, and the rigid connection of the ring with the levers is made at an acute angle with the location of the attachment points of the levers in the lower part of the ring.

The execution of the grips in the form of a single ring significantly increases the force of pressing the gripper onto the cylinder by reducing the distance between the upper and lower points of contact of the gripper with the balloon, which leads to an increase in the frictional force between the grippers of the stretcher and the balloon. The supply of the pad levers, the definite location of their places and the knot of fastening the levers to the ring ensures that the cylinder is seized when the load is applied. IOSH10K. A wedge fixed by the pads prevents the stretcher from moving relative to the cylinder and prevents the force from gripping the container to decrease.

In addition, the execution of the capture in the form

Rings allow you to put the semi-stretcher on the balloon in a vertical position by dressing them sequentially through the top of the balloon.

Claims (1)

with the subsequent lowering it in a horizontal position, holding the levers of the upper half-rake. FIG. 1 shows the proposed carriers; in fig. 2 - stretcher in the pre-transport position; in fig. 3 - section A-A of FIG. one; in fig. 4 - stretcher in the transnort position; in fig. 5 is a section BB of FIG. 2; in fig. 6 shows a section bb of FIG. 4. In the pretransport position between the plates 6 and the surface of the bdllon 4, a certain gap 7 is formed due to 90 and / 180 °. At the moment of lifting the stretcher with the balloon 4 under the force of gravity of the latter, the gripper 3 leans against the stop into the balloon 4, and the levers 5 rotate and jam the balloon 4 with the tabs 6. The jamming is due to the geometry of the attachment of the levers 5 to the gripper 3, as a result of which the lining 6 successively d the position with a gap y, the position, then smashed due to the elasticity of the levers 5i, slipping along the curvilinear surface of the cylinder 4, reach the maximum distance A at the level of the horizontal plane passing through the axis of the cylinder 4 and then on the curvilinear surface of the cylinder 4, elastic ρр {agami 5 at a height B are approaching, and B. At that, the bagtsyun 4 is fixed at three points: from the bottom by a gripper 3, and from above by two lining 6 with a force proportional to the elasticity of the levers 5 and depending on the magnitude of the angles a. and | 3. After delivery of the container 4 to the required place, the stretcher is lowered to the ground. When pressing the handles 7 from above, the levers 5 tilt down, nak) 6, the slides along the curvilinear surface of the cylinder 4 move in the opposite direction at O, and the grip 3 assumes a vertical position, forming a gap 6, which makes it possible to remove the stretcher from the arm 4 If it is necessary to install the delivered cylinder 4 into a vertical position, the gap is reached only at the rear half-ram 2, which is then shifted somewhat forward. The cylinder 4 is lifted to a vertical position by means of levers 5. The stretcher consists of two half-shears 1 and 2, each of which has a grip 3 in the form of a ring, the inner diameter of which exceeds the outer diameter of the cylinder 4 by the size of the gap 6. To the grip 3 is rigid levers 5 attached along the cylinder 4 are attached. The angle a between the grip plane 3 and the axis of each lever 5 depends on the size of the gap 5, but the condition is 90. The attachment points of the grommet 5 to the grip 3 are 4 with some central angle from each other. hung ie the configuration of the arms 5 about necessarily condition is / 3180. The levers 6 are rigidly attached to the levers 5. The distance from the gripper 3 to the linings 6 is chosen so that the deformation of the levers when the cylinder is seized does not extend beyond the elastic deformation zone. The levers 5 are provided with handles 7. To the gripper 3 there are attached supports 8 with curved plates 9. On the upright cylinder 4 each of the two semi-mounts I and 2 is worn by the grips 3 through the top of the cylinder 4. At the same time the handles 7 each half-mounts 1 and 2 are in opposite directions. The gap provides free dressing of the semi-mowers 1, 2 on the cylinder 4.. To transfer the stretcher to the pre-transport position, the upper semi-stretcher 1 is tilted towards the pre-transport position and, pressing the handle 7 semi-bar 1, adjusts: 1: avat 3 until the cylinder is jammed 4. Podgzhurzhiva wedged cylinder 4 by the handles of 7 semi-mowers 1, the cylinder 4 is lowered until the plate 9 stops against the ground. Then the bottom of the container 4 is lifted and the semi-stretcher 2 is moved to the rear end position, after which the bottom of the cylinder 4 is lowered. The advantages of the invention are the possibility of a forced balloon in nozzles, the force of which is sufficient to overcome the loads from shaking the balloon, when workers are bred over rough terrain by accidentally stretching the semi-mounts to the side and to compensate for losses in the forces of friction of the balloon when it is transported on inclined surfaces The possibility of lowering the cylinder to a horizontal position by the arms of the semi-mowers improves their ease of use. The invention of the stretcher for gas cylinders, containing the clamps, rigidly connected by levers with handles, characterized in that. in order to increase safety and convenience in their work, the rigs are fitted with pads and are connected with hooks made in the form of rings, at an acute angle with its lower part.
