Description

I

The invention relates to laboratory equipment and is intended to fasten instruments, in particular Dewar vessels, to its supporting surface, for example, to a table top of a lifting table.

Lifting tables are known, comprising bases, a rack fixed on the base, a support platform placed on the rack with the possibility of reciprocating movement in the vertical direction, and a lifting mechanism connected to the platform fl.

Also known is a lifting table containing a base with adjustable legs, a hollow cylindrical rack, vertically mounted on the base, a steering wheel with a power nut, placed on the upper end of the rack, a lifting screw placed inside the rack, a support platform with flanging, Fixed on the upper end of the lifting screw and restrictive

sliders, movably located on the support platform 2.

However, the known tables are characterized by the inconvenience of fixing devices and insufficient safety conditions when working with liquefied gases or toxic substances, as well as the inability to use robots when attaching or replacing the device.

to

The purpose of the invention is to improve the convenience of operation and safety by automating the process of fastening devices and parts on the supporting platform.

The goal is achieved by the fact that the table is equipped with a casing placed under the support platform on its flanging with the possibility of reciprocating movement in a vertical

20 direction relative to the platform and the lifting screw, two main bellows, coaxially mounted inside the casing outside the lifting screw, additional bellows connected to the main ones, and spring loaded joints, connected with additional additional bellows with restrictive cords. The drawing shows a table, a general view, a longitudinal section. The lifting table contains a base 1 with adjustable supports 2, a hollow cylindrical rack 3, vertical on the base 1, a steering wheel k with a power nut 5 placed on the upper end of the rack 3, a lifting screw 6 placed inside the rack 3 supporting Platform 7 with the flange 8 mounted on the upper the end of the lifting screw, the limiting sliders 9 movably located on the supporting platform 7, the casing 10 placed under the supporting platform 7 on its sampling 8 with the possibility of reciprocating movement in the vertical direction relates flax platform 7 and lifting screw 6, two main bellows 11 and 12, coaxially installed inside the casing 10 outside the lifting screw 6, additional bellows 13 connected to the main ones and spring loaded ti 1y connecting additional bellows 13 with restrictive sliders $ Lifting table works as follows. When rotating the steering wheel k with the power nut 5 zint 6, limited by the pin 15 from the rotation around the axis, moves back and forth (up or down). Since the support platform 7i is fixed to its topce, the back-and-forth support moves along with it. In order to clamp an object, for example, a Dewar vessel (not shown in the drawing) on the supporting platform, rotate the casing 10. The distance between the platform 7 and the casing 10 changes (this distance increases to bring the restricting sliders 9 to the initial state) and change The height of the bellows 11 and 12, from the cavity 16 of which the fluid moves in the cavity of the bellows 13, increasing (or decreasing) their size, i.e.; Tires 14 are moved with an unequal arm 17. The sliders 9 approach (or disperse) and clamp (or release) the fixed object. The proposed table is characterized by simplicity of design, ease of use and increased safety in operation. It can be widely used in laboratory technology for fastening various devices and parts. Claims of invention. A lifting table containing a base with adjustable supports, a hollow cylindrical strut, vertically fixed on the base, a steering wheel with a power nut placed on the upper end of the rack, a lifting screw placed inside the strut, a supporting platform with flanging fixed on the upper end of the lifting screw , and restrictive sliders, movably located on the supporting platform, characterized in that, in order to increase the convenience of operation and safety by automating the process of fastening devices and parts on the support platform, it is equipped with a casing, located under the support platform on its flanging with the possibility of reciprocating movement in the vertical direction relative to the platform and the lifting screw, two main bellows, coaxially installed inside the casing outside the lifting screw, additional bellows, connected to the main and spring loaded joints connecting additional bellows with restrictive sliders.
