This is provided by the interaction of the flange 21 of the hub 22 of the asterisk 16 with the half rings 23, rigidly fixed to the flange 24 of the upper part of the housing 19 bolts. 25. The very same hub 22 sprocket 16 is planted rotatably in the bore 40

The sa 19 and the asterisks 16 are the stand 10, which, in addition, has the ability to rotate with the asterisk 16 around the vertical axis. This is ensured by the fact that the post 10 is connected with an asterisk 16 through each stop 49 and 50 of the locking mechanism of the synchronization circuit 17 in the form of a cam clutch 53, one half-coupling 54 of which is rigidly mounted on the shaft 55,

The rotary mechanism 18 also includes a fixed axis 36 fixed to the bottom of the rack 10 in its opening 34 by means of a pin 35, the ends of which are rotatably mounted on needle-like bearings 37, rollers 38 fixed from axial displacement with end washers 39. The supporting platform 13 of each rotary support 9 is provided with a ring 40, the inner part of which is placed in a groove 41. The latter is formed on one side by an annular protrusion 42 flange 11 racks 10,

and on the other (upper) - lower end 43

The coils of the 45 wheel ramp 7 freely lie on the respective rail tracks x 3 and 4 and have the opportunity, while working, to freely slide relative to them.

In this case, the support platform 13 is rotatable relative to the ring 40, and the ring 40 itself is provided with sliders 46 rigidly fixed on it and placed by means of these sliders with the possibility of vertical movement together with the support platform 3 in the guides 47, which are rigidly mounted on the base 2 and ring 40 is fixed against rotation.

The rack 10 with the support platform 13 is spring-loaded upwards relative to the body by the spring 48, which is placed in

th way m 4.

Each locking mechanism 49 and 50 of the synchronizing circuit 17 is made in the form of a cam clutch 53, one half-coupling 54 of which is rigidly mounted on the shaft 55,

located in supports 56 and 57 of the base 2

and part of the same mechanism 49 and 50 stop. Let mechanism 49 be kinematically associated with drive 58 of this

the mechanism 49. In addition, the mechanisms 49 and 50 of the locking mechanism are kinematically connected to each other by means of bevel gears 59 rigidly mounted on the ends of their shafts 55, interacting with each other.

The other half coupling 60 of the cam coupling 53 is included in each locking mechanism 49 and 50 and is placed with the possibility of movement along the sliding key 61 in the support 62 of the base 2. The coupling half 60 is spring-loaded 63 with respect to the support 62 in the direction of the first coupling half 54. Safety of the conveyor half coupling 60 is equipped with a stopper 64, located with the possibility of movement in the bracket 65 of the support 62, one end of which interacts with the socket 66 in the coupling half 60, and the other end is connected with the pusher of the electromagnet 67 fixed on D 62. The stopper 64 is biased with a spring 68 in the direction of the longitudinal axis of the coupling half 60.

Coupling 54 of the cam coupling 53 is provided with a vertical lever 69 rigidly attached to it, and the coupling half 60 has a toothed device in the form of one or several teeth 70 interacting in one of the extreme positions of the coupling half 60, namely, when its cams are coupled with the half-coupling cams 54 with corresponding branches 51 and 52 of the synchronization chain 17. In case the teeth 70 are several, they are arranged with a pitch equal to the pitch of the synchronization chain 17. At the points of interaction, the teeth 70 with the branches 51 and 52 are mounted on the base 2 of the limiting points Orae 71, shelves 72 are prevented by the branches 51 and 52 of the chain 17 from sagging, and wall 73 - from engagement in the horizontal direction away from the teeth 70.

Each trolley 1 is provided with paired retractable lugs 74 and 75 mounted respectively on one of the longitudinal 76 and one of the side 77 sides of the trolley 1 symmetrically with respect to the respective transverse, longitudinal axes thereof. Each retractable stop 74 and 75 has the ability to move in the vertical direction, is located in the guide 78, rigidly fixed to the frame 6 of the trolley 1, and is fixed in the working position by a finger 79 inserted into one of the holes 80 in the sliding stops 74 and 75. during the operation of the conveyor, they can interact with the upper ends 81 of the vertical arms 69 of the locking mechanisms 49 and 50 of the respective sections 5 of the intersection of the railways 3 and 4, which have limit switches (not shown) of any type, which are activated by interaction with contact stops or plates of carriages 1 and serving for switching

electromagnets 67 and uncoupling coupling halves 60 immediately before the engagement of the sliding stops 74 and 75 with the upper ends 81 of the vertical levers 69 c. The electromagnets 67 can operate in two cases: when turned on by means of the indicated limit switches, or when the actuator 58 is turned on the locking mechanisms 49 and 50 .

The height / cams of the coupling 53 must be

equal to or greater than the height C of the head of the tooth 70 of the half-coupling 60, in order to ensure the opening of the tooth 70 and the synchronizing circuit 17 with the axial movement of the half-coupling 60. The mechanisms 49 and 50 of the stop are also equipped with stabilization units 82 of the levers 69 in the vertical position, which include t spring 83, located symmetrically relative to the axis of the cam clutch 53 and fixed by one end on the base 2, and the other -

0 on the bracket 84 of the coupling half 54. The latch 85 is mounted with the possibility of axial movement in the supports 86 of the support 56 and is spring-loaded relative to them by the spring 87 in the direction of the vertical lever 69. When

5 this spherical end 88 of the latch 85 interacts in a vertical position of the lever 69 with a spherical socket 89, made on its surface 90.

The actuator 58 of the locking mechanisms 49 and 50 may be electromechanical or pneumatic. In the first case, it contains an engine 91 mounted on a base 2 and a gear reducer 92, an asterisk 93, on the output shaft of which is connected by a chain 94 with an asterisk 95 fixed on the shaft 55 of the locking mechanism 49. In the second ROM case, the driver 58 contains a pneumatic cylinder 96 mounted on base 2, the stem of which is connected to a rail 97 placed on guide 98 also fixed on base 2. The rail 97 in turn interacts with a gear wheel 99, rigidly mounted on the shaft 55 (elements of electropneumatics not shown).

The length of the vertical lever 69 of the mechanisms 49 and 50 of stopping of each of the next 5 section 5 of the intersection of railways 3 and 4 in the direction from the beginning of the conveyor to its end and from the main track 3 to the side more than the length of the lever 69 of the previous section 5 of the intersection on a certain fixed

0 is the value of h, which is equal to the pitch / holes 80, made in the extendable supports 74 and 75 of the trolley 1,.

Trolley conveyor works as follows.

5 Before starting, all the mechanisms of the sections 5 of the intersection of the trunk 3 and lateral 4 tracks are in the initial position. The pillars 10 of all pivot bearings 9 are lowered, the springs 48 are at the same time compressed and held in this position due to the interaction of the teeth 7.0 of the locking mechanisms 49 and 50 with the corresponding branches 51 and 52 of the synchronizing chains 17. The levers 69 of these mechanisms are in a vertical position and stop in it by means of clamps 85.

Then, the extension stops 74 and 75 of the conveyor carts 1 of the conveyor are adjusted, i.e. the farther from the beginning of the conveyor the crossing section 5 is where the wheels 7 of the trolley 1 turn, the higher the extension stop 74 rises, and vice versa

The sliding stop 74 interacts with the upper end 81 of the vertical lever 69 of the mechanism 49 and rotates this lever 69. The end 88 of the retainer 85 comes out of the socket 89 on the surface 90 of the lever 69. One of the springs 83 expands more than the other. Together with the rotation of the lever 69 of the locking mechanism 49, both coupling halves 54 of the cam sleeves 53 of the locking mechanisms 49 and 50 are rotated, because their shafts 55 are kinematically connected to each other by means of bevel gears 59.

As a result of the rotation of the coupling half 54 and the interaction thanks to this cam

the closer to the beginning of the conveyor lies the required 15 half couplings 54 and 60, the half coupling 60 both

The lower crossing section 5, the lower the required number of steps t, is pulled out by the sliding stop 74 and fixed in this position with a finger 79 inserted into the corresponding hole 80 of the sliding loops 49 and 50 of the stopper are pressed, moving along the axis and compressing the spring 63. Together with the half couplings 60 the teeth 70 are also shifted, disengagement from the engagement respectively with the branches 51 and 52 of the synchromes 74 and 75. In this case, only the lowering chain 17 and its opening are adjusted.

in the direction of movement, the sliding stop 74, and the rear stop 74 rise to the highest position. When changing the direction of movement, the front and rear struts of all the rotary supports 9 of this intersection section 5 begin to move simultaneously upwards under the action of the springs 48. Simultaneously with this.

lower sliding stops 74 change the role - 25 due to the interaction of the rollers 38 on the horse. From the retractable stops 75 located along the side 77 of the trolley 1, the right or left retractable stop 75 is adjusted respectively, depending on which way, left or right

cent axes 36 with screw grooves 20 in the housings 19 of the swivel supports 9, all the support pads 13 rotate 90 °. The rings 40 thus move only in the vertical direction due to the mutual rail track 3, and the action of its CLEANERS 46 with the trolley 1 still moving after its wheels 7 are rotated by 90 °.

Under the action of a drive (not shown), the cart 1, with the motor vehicle equipment installed on it and being repaired, begins to move along the trunk track 3 in order to deliver the cargo to the appropriate post for repair. In this case, due to the fact that the pillars 10 of all the pivot bearings 9 are lowered, the sections 45 of the exit of the pivot bearings 9 are in a horizontal position and the carriage 1 freely passes through all the intersection areas 5 on which the rotation of the wheels 7 is not foreseen, since the retractable stop 74 trolley 1 passes over

guides 47. The sections 45 of the exit of the wheels 7 are installed in an inclined position, the connection trunk 3 and lateral 4 rail tracks with support pads 13.

Upon further movement of the trolley 1, the retractable stop 74 ceases to interact with the end 81 of the lever 69 and the latter returns to a vertical position under the action of springs 83. As a result, the coupling half 60 under the action of the spring 63 moves to the coupling half 54 and the tooth 70 engages with the branches 51 and 52 of the synchronizing circuit 17, its stopper, and hence the pillars 10 of the pivot bearings 9, against displacement. 81 vertical levers 69 of these 45 electromagnets 67, and half coupling 60, due to electroautoconnects, work

5 intersection plots without hitting them. After the front wheels, in the course of the movement of the carriage 1, the wheels 7 intersect the adjacent portions 45 of the exit of the required intersection portion 5, which are

are fixed against axial movement by stoppers 64.

The mechanism 18 of rotation of the supports 9 turns out to be prepared for operation, and the levers 69 are fixed in a vertical horizontal position, 50 are activated by locks 35. Trolley 1 is a continuous switch from the corresponding stop of the trolley 1 and turns on the electromagnets 67 of the locking mechanism 49 and 50 of this section 5 of intersection, which engage the stoppers 64, compressing the springs 68. Thus, the locking mechanisms 49 and 50. prepared for operation. With further movement of the trolley 1 forward in the direction of movement of the trolley 1 out 55

The engine moves all four wheels 7 simultaneously onto the supporting platforms 13 of the uprights 10, raised above the rail tracks 3 and 4. Now, to turn the wheels 7, it is enough to turn on the drive 58 of the locking mechanisms 49 and 50. At the same time, the electromagnets 67 half couplings 60 and the half couplings 54 with levers 69 rotate at the same time. The sliding stop 74 interacts with the upper end 81 81 of the vertical lever 69 of the mechanism 49 and rotates this lever 69. The end 88 of the retainer 85 comes out of the socket 89 on the surface 90 of the lever 69. One of the springs 83 is stretched more strongly than the other. Together with the rotation of the lever 69 of the locking mechanism 49, both coupling halves 54 of the cam sleeves 53 of the locking mechanisms 49 and 50 are rotated, because their shafts 55 are kinematically connected to each other by means of bevel gears 59.

As a result of the rotation of the coupling half 54 and the interaction thanks to this cam

5 half couplings 54 and 60, half couplings 60 both

the locking mechanisms 49 and 50 are pressed, moving along the axis and compressing the spring 63. Together with the coupling halves 60, the teeth 70 are also shifted out of the engagement, respectively, with the branches 51 and 52 of the synchronizing circuit 17 and disengaging it.

In this case, the struts 10 of all pivotal supports 9 of this intersection section 5 start simultaneously moving upwards under the action of springs 48. Simultaneously with this.

Due to the interaction of the rollers 38 at the end, due to the interaction of the rollers 38 at the ends of the axles 36 with the screw grooves 20 in the housings 19 of the swivel supports 9, all the support sites 13 are rotated by 90 °. The rings 40 thus move only in the vertical direction due to the interaction of their CLEANERS 46 with the fixed

guides 47. The sections 45 of the exit of the wheels 7 are installed in an inclined position, the connection trunk 3 and lateral 4 rail tracks with support pads 13.

Upon further movement of the trolley 1, the retractable stop 74 ceases to interact with the end 81 of the lever 69 and the latter returns to a vertical position under the action of springs 83. As a result, the coupling half 60 under the action of the spring 63 moves to the coupling half 54 and the tooth 70 engages with the branches 51 and 52 of the synchronizing circuit 17, its stopper, and hence the pillars 10 of the pivot bearings 9, against displacement. Electromagnets 67, and half coupling 60, due to electroautomatics, work

mathematics electromagnets 67, and half coupling 60

are fixed against axial movement by stoppers 64.

The mechanism 18 of rotation of the supports 9 is prepared for operation, and the levers 69 are fixed in the vertical position by the latches 35. Trolley 1, continued 5

The engine moves all four wheels 7 simultaneously onto the supporting platforms 13 of the uprights 10, raised above the rail tracks 3 and 4. Now, to turn the wheels 7, it is enough to turn on the drive 58 of the locking mechanisms 49 and 50. At the same time, the electromagnets 67 of coupling half 60 and the coupling half 54 with levers 69 are actuated by the actuator 58 at the same time. The uncoupling of the synchronizing circuit 17 occurs in this way.

As soon as the tooth 70 gets out of engagement with the branches 51 and 52 of the synchronization chain 17, the legs 10 of the pivot bearings 9 start under the action of the weight of the carriage 1 with the load placed on it, which is standing with its wheels 7 on the support platforms 13, lowered. At the same time, due to the interaction of the bushings 38 of the axles 36 of the uprights 10 of the rotary supports 9 with screw grooves 20 of the housings 19 of the supports 9, the uprights of the uprights 10 are rotated together with the supporting platforms 13 with the wheels 7 of the trolley 1 mounted on them 90 °.

Since the actuator 58, turning the coupling half 54 with the lever 69 at a certain angle required to open the synchronizing circuit 17, disconnects that at the end of the rotation of the wheels 7 of the trolley 1 all the elements of the locking mechanisms 49 and 50 of the synchronizing circuit 17 return to their original position under the action of the springs 83, 63, 68 and 87. The cart 1 continues its movement along the side rail tracks 4. When the cart 1 reaches the crossing section 5, which is located on the side rail tracks 4, the process of turning the wheels 7 is carried out in the manner indicated to the difference that in this case, the front of the trolley 1 of the sliding stopper 75 interacts with the vertical lever 69 of the locking mechanism 50 interacting with the side branch 52 of the synchronizing branch 17. After turning the wheels 7 on this crossing section 5, the trolley 1 moves to the corresponding repair post and remains there with the unit until the end of the repair.

After the repair is completed, the cart 1 moves to the beginning of the conveyor. The turning operation of the wheels 7 is carried out as indicated. The difference is that the front and rear sliding stops 74 and 75 are swapped and the sliding stops 74 and 75 are already adjusted, which, in the course of the movement of the trolley 1, have become front.

After the new unit to be repaired is loaded onto the cart 1, the process of transporting the cart 1 to the proper repair post is repeated in the same way.
