Description

The invention relates to a lifting machinery industry, namely to devices for mounting a bridge crane.

The purpose of the invention is to increase the ease of operation.

Figure 1 shows a device for mounting a bridge crane, a general view; figure 2 - section aa in figure 1; on fig.Z - section BB in figure 1; figure 4 is a section bb In figure 1; on fig.Z - section GG on figure 1; nafig.b - the moment of rotation of the cantilever frames around the guides by means of a pull mechanism.

The device for mounting an overhead crane contains two cantilever frames 1 with brackets 2 and 3, equipped with rollers 4 and 5, covering a guide 6, equipped with an arm 7, covering the columns 8 of the workshop, and a collar 9 equipped with a support roller 10, covering the bottom crane beam 11. The collar 9 is C-shaped and installed in a groove 12, made in the lower part of the console frame 1. The house 9 is equipped with a screw 13 installed in its upper part and interacting with the lower part of the console frame 1. On the columns 8 of the workshop under guide 6 installed ontazhnye .14 tables equipped with 15 hoists, hydraulic jacks .naprimer interacting with collars

7. The collar 9 is associated with a rotation drive 35 of the crane beam 11, and by

cantilever frame 1. The drive includes a flexible link 16, passed through the diverter roller 17, mounted on the farm 18 of the workshop, and the traction mechanism 19.

the lifting mechanisms 15 lower the guide 6 together with the cantilever frame 1 until they touch the supporting rollers 22 with the crane girder 1

further use.

On each cantilever frame 1 is installed - 40, after which the device is ready for individual winch 20 with pulley blocks 21. The lower part of the cantilever frame 1 is equipped with support rollers 22. Guide 6 is equipped with an anvil 23.

Formula invented The device works as follows. 45 Before mounting the bridge crane on A device for mounting an overhead crane, containing cantilever frames with supporting rollers installed in their lower parts with the possibility of tables 14, mounted on Q columns, resting on the crane runway and rollers - 8 workshops, install underwater fenders KSSH in the upper part for gripping The bottoms 15, for example hydraulic jacks, then install cantilever frames 1 on crane girders 11, while the crane beam -11 below covers 5 Gates of the longitudinal axis of each directional roller 10 of the collar 9, and the top and collar covering the shelf supporting rollers 22 of the cantilever frame 1, a crane beam, characterized by round circular sections attached to the columns above the crane girders, drives of the turn of the wok frame guide 6, provided with clamps 7 covering the columns 8 of the workshop, Rollers 4 and 5 of brackets 2 and 3 mounted on console frame 1 are then rolled. Then console frames 1 roll over crane girders 11 to stop 23, after which the fully assembled bridge crane slings t, using winches 20 and tackle 21 lift above crane beams 11 and roll the cantilever frame 1 with a bridge crane into the workshop for a distance sufficient to install the bridge crane on the crane beams 11. Then the bridge. The crane is winched by means of winches 20 and tackle 21 onto crane girders 11 and spread out. Then, using a screw 13, lower the collar 9 with the Yun support roller, allowing the console frame 1 to turn after raising the guide 6 together with the console frame 1 by means of the lifting mechanisms 15. With the help of the latter, lift the guide 6 together with the cantilever frame 1 until the support rollers 22 are released from the engagement with the crane crane 11. Then, using the traction mechanism 19, the cantilever frame 1 is lifted up to allow the bridge crane installed on the crane beams 11 to pass under it, after which the latter b shop. Then, the cantilever frame 1 is lowered into a vertical position and with the help of a screw 13, the clamp 9 is raised with the support roller 10 until it is in contact with the lower part the lifting mechanisms 15 lower the guide 6 together with the cantilever frame 1 until the supporting rollers 22 come into contact with the crane beam 11, further use. after which the device is ready after which the device is ready for Invention Formula A device for mounting an overhead crane, containing cantilever frames with supporting rollers installed in their lower parts with the ability to rest on the crane runway and the KSSH roll in the upper part for wrap around the longitudinal axis of each rail and clamps covering the shelf below. crane girders, characterized by round circular sections attached to the columns above the crane girders, the wok frame rotation actuators so that, in order to increase the convenience of operation, it is equipped with 313120564 enclosing the columns of the clips, guides to the mounting tables and dimensions are attached guides, unwired on the latter by mechanisms unmounted on the columns for the enclosures of the clips.
