The jack is equipped with hinged auxiliary orthanams and a device for connecting them to the hydraulic cylinder body 5 s par., 6 silt

Description

The invention relates to a tool intended for installation work

The purpose of the invention is to give it new operational capabilities.

In Fig.1 shows a universal hydraulic jack in Fig.2 - a universal hydraulic jack with grips, in Fig 3 - a universal hydraulic jack with a plate; Fig. 4 shows a univeal hydraulic jack for clamping pipes; figure 5 is a universal hydraulic jack for bending pipes; figure 6 is a universal hydraulic jack with handles for carrying it

The universal hydraulic jack consists of a hydraulic cylinder 1 (Fig. 1), the housing 2 of which is connected to the support platform 3, on which the hand pump 4 is located. On the housing 2, on the side of the load-carrying member 5, connected to the rod 6 of the cylinder 1, there are devices 7 and 8 for the connection of the housing 2 with mounted auxiliary organs) and 10, made in the form of h with hinges at the ends. The devices for connecting 7 and 8 are made in the form of loops arranged symmetrically to each other relative to the axis of the housing 2, and their axis

placed perpendicular to the longitudinal axis of the housing

Depending on the work performed, the jack can be equipped with a common bar 11, gripping levers 12 and 13 and adjustable rods 14 and 15 (Fig. 2) or a plate 16, the plane A of which is directed to the load-carrying body 5 (Fig. 3) or sawtooth angular clamps 17 and 18, one of which is mounted on a bar 19 (Fig. 4) or a common bar 11, having along the entire length of the hole under the axis of the rollers 20 and 21 and a support 22 with a curved surface (Fig. 5) or handles 23 and 24.

To lift the load with a manual pump 4, the working fluid is supplied to the hydraulic cylinder 1, the rod 6 lifts the load.

When using a universal hydraulic jack as a puller (Fig. 2), a connecting strip 11 is attached to the rods 9 and 10. Depending on the size of the part to be removed, using a different arrangement of holes in the connecting strip 11 and adjusting the rods 14 and 15, grips 12 and 13 set so that they tightly wrap around the disassembled assembly.

and 10, a plate 16 is fastened onto a plane A of which parts for pressing or straightening with the rod 6 are mounted.

When using the universal clamping jack (Fig. 4), for example, when threading a pipe, the pipe is inserted into the angular notch of the clamp 18 and the rod 4 is pressed against the sawtooth surface of the clamp 177 which keeps the pipe from turning.

When using the universal jack for bending pipes (Fig. 5), the bar 11 is connected and the bar 11 is connected. In the hole B of the bar 11, the rollers 20 and 21 are fixed. Depending on the size of the pipe, the sizes of the rollers 21 and 20 change and their installation in holes x B

The pipe is inserted between the rollers 20 and 21 and the support 22. When extended, the rod b through the support 22 bends the pipe to the desired size.

To carry the universal hydraulic jack, handles 23 and 24 are connected to rods 9 and 10

The use of a universal jack reduces the time for repair and installation work. The kit is lightweight and can be quickly delivered to hard-to-reach places by one person.

Claims (2)

The claims 1, a jack containing a support plate and a hydraulic cylinder connected to this platform by a housing having a cross section smaller than the area of the support platform, and a load-bearing member connected to the hydraulic cylinder rod, characterized in that, in order to expand its operational characteristics, it is equipped with hinged auxiliary ortans and a device for connecting them to the body of the hydraulic cylinder, the latter including rods attached at one end to the body by means of hinges and loops diametrically located on this housing from the side opposite the supporting platform, and the hinges are placed perpendicular to the longitudinal axis of the housing. 2. Jack pop 1, characterized in that the hinged auxiliary body comprises gripping arms pivoting towards each other, fixed at one end on a common bar having openings for connecting to said arms and for moving them along it and for hinged with second ends of the hitch with the possibility of placement above the load-carrying body. 3 Jack pop 1, characterized in that the hinged auxiliary body contains a horizontally oriented plate with a flat pressing surface facing the load-bearing member and having holes at the ends for connection by means of hinges with holes second ends t g 4Jack pop 1, characterized in that the hinged auxiliary member comprises a pair of rollers connected by horizontal axes to a common a strip having along the entire length of the hole under the axis of the rollers and their rearrangement and connection by means of hinges with holes of the second ends of the rod with the possibility of placement above the load-carrying body, and a support with a curved working surface facing the rollers, made with the possibility of connection with a load-carrying body 5 Jack pop 1, characterized in that the hinged auxiliary body each contains clamps with a sawtooth angular recess each, one of which is fixed to a bar having holes for connection by means of hinges with the holes of the second ends of the rod, and the other is made with the possibility of connection with the load-bearing body and the location of its recess towards the reciprocal recess of another clamp 6 A jack according to claim 1, characterized in that the hinged auxiliary member comprises handles adapted to connect each of them to an opening of the second end of the corresponding rod. - b gpf 6t ggpf Z / .SWU At 7 go
