(5) DEVICE FOR BATHING

one

The invention relates to the electrochemical and chemical treatment of products with aggressive volatile liquids, in particular, to the elements of the tooling, and can find a wide use in the workshops of the chemical industry.

A device for sheltering a bath is known, in which a shaft-drum with a web is located on a carriage whose drive is made in the form of a running wheel and a driving pulley of an STZ.

However, in this device is a carriage. moves around the surface of the bath, which dramatically increases its dimensions and prevents movement of mechanisms serving it over the bath, the shaft drive is located on one side, and as the drum moves along the bath, the cover can be tilted.

Closest to the present invention is a bath lid containing a flexible lid chain drives.

drum with axles, electric drive and guides G2.

A disadvantage of the known device is its fragility due to insufficiently smooth feeding of the cover, as a result of which its m-, reclos and breaks can occur.

The purpose of the invention is to increase the durability of the device by eliminating distortions and breaks in the flexible

10 canvases.

The goal is achieved by the fact that the device for covering the bath, containing a drum with axes, a flexible cover, guides, chain drives

Claims (2)

ts and electric motor, equipped with paired friction clutches with bushings located on each axis of the drum, rollers mounted on the end of the Q axis of the drum inside with a guide and fork with teeth kinematically connected with the bushings of friction clutches, and the chain drive is made in the form of a mobile and stationary chain branches located one above the other and sprockets mounted with the possibility of interaction with them, with the asterisk of the lower fixed branch mounted on the drum axis between the friction clutches, e the asterisk of the upper the movable wind is kinematically connected with the axis of the electric motor and the fork, the base of which is fixedly attached to the extreme link of the mobile chain. The device is provided with a box-shaped bracket for the chain branches. FIG. 1 given the proposed device, the overall appearance; in fig. 2 is a view along the track A in FIG. one; in fig. 3 section bb in fig. one; in fig. C node G in FIG. 1. The device consists of a drum 1, with a flexible lid wound on it, mounted on axles 2. The end of each axis is provided with a roller 3 placed inside of the guide k, To the body of the guide k by means of brackets 5 and 6 Box-shaped guides 7 and 8 are attached. Inside the guide 7 there is a movable drive branch 9, and inside the guide 8 there is a fixed branch 10. On the axis 2 of the drum t there is an asterisk 11, friction sleeves 12 and 13 with sleeves And and 15, which fastened with teeth 16 and 17 forks 18. Axis 19 of electric motor 20 by means of the flexible element 21 is associated with an asterisk 22. The guides, 7 and 8, are mounted on the 2k body of the bathtub 25 by means of the pendant element 23. The device operates as follows. To remove the cover from the concealed bath (the drum is in the extreme left position of Fig. 1). The electric motor 20 is turned on and the sprocket 22 begins to rotate, its tooth being in engagement with the links of the upper moving branch 9 of the chain drive, The latter translational motion in the guide 7, which is connected via fork 18, whose teeth 17 and 16 to the bushings 14 and 15 of the friction clutches 12 and 13, is transmitted to the drum 1. The movement of the drum 1 is transmitted through the friction clutches 12 and 13 to the sprocket. 11, which rolls back along the links of the fixed branch 11 of the chain drive, laid 9 04 inside the guide 8, and begins to transmit rotational motion to the axis 2 of the drum 1, while the flexible cover begins to wind on the drum 1, and the free part of the moving branch 9 is assembled into a conveyor 26. To cover the bath, rotating; From motor 20, an asterisk 2 feeds from the container 2b a movable chain drive branch 9, the forward movement of which through the plug 18, the teeth of which 17 and 16 are attached to the sleeves I and 15, is transmitted to the drum 1. The asterisk 11, mounted on the axis 2 of the drum 1, begins to roll away through the links of the lower stationary branch tO of the chain drive and due to the coupling of the teeth of the sprocket 11 with the links of the branch 10 simultaneously receives a rotational movement, which is transmitted to the axis of the drum 1. The drum 1 begins to rotate, the flexible lid begins to wind off the bar ana t and bath cover 25, The apparatus for shelters bath permits to increase its durability due aligning torque drum Formula invention t. A device for sheltering a bath, containing its drum with axles, a flexible cover, guides, chain drives and an electric motor, is characterized by the fact that, in order to increase the durability of the device by eliminating distortions and ruptures of the flexible web, it is equipped with paired friction couplings with bushings located on each axis of the drum, rollers mounted on the end of the axis of the drum inside the guide and fork with teeth kinematically connected with the sleeves of the friction clutches, and the chain drive is made in the form of a mobile and stationary The chain is located one above the other and the sprockets installed with the ability to interact with them, while the asterisk of the lower stationary axle is mounted on the drum axis between the friction clutches, and the asterisk of the upper movable branch is kinematically connected with the axis of the electric motor and the fork, whose base 5 is fixed with the extreme Even of the mobile chain. 2. The device according to claim 1, wherein it is provided with a box-type bracket for the chain legs. 31820 Sources of information taken into account during the examination t.
