Description

(54) BILATERAL ACTION PUSHER The invention relates to transport equipment and can be used, for example, in power transmission carriages working in plants of building ceramics, sanitary equipment, refractory materials, as well as a number of other industries for pulling on an electric transfer car and colliding from her drying, roasting and other trolleys in automatic mode from two sides. . A double acting pusher is known for tightening and pushing the kiln cars, which can pull and push the cars into one well. The main body, two telescopic carriages, is driven by the hydraulic cylinder. At the end of the outer carriage there are two pairs of lugs, one of which is for tightening the trolley and another for pushing. The operator controls the y with the help of the lever through this thread and the levers CX). The closest in technical essence and achieved result to this pusher is a double-acting pusher containing a rod with a gripping device located on it in the form of stops interconnected and a retainer, a drive for moving the rod and. a lever control system of a gripping device, with a C2 drive}. However, the rigid connection of the stops of the said pusher with each other and with the two-arm switching lever leads to the breakdown of one of the links of the system during the squeezing of the stops of the trolley. The springs in this pusher cannot compensate for the forces that arise; i because they are intended only for this purpose, in order to restore the stops to their original position after the trolley passes over them,. The purpose of the invention is to increase the reliability of the operation of the pusher by ensuring the automatic switching of the gripping device located at the moment of switching under the influence of the pushed trolley. This is achieved by the fact that. A double-acting hoist with a bar with a catch in the form of stops located on it

interconnected and retainer, rod movement guide and lever cHCTeiviy of the gripping device with an actuator are provided with interconnected control and switching spring of the linkage connecting the lever control system with the gripping device, and the stops are connected with the switching bar and the control bar connected to the retainer.

Figure 1 shows a kinematic pusher diagram; Fig 2: pusher view; fig.Z - the same view in the psgge; Fig, 4 - the left side of the pusher, in the switched position of the stops; on fig.Z - section aa in figure 2; figure 6 - section bb in figure 2; figure 7 - section bb In figure 2; FIG. 8 is a cross-section of FIG. 2

The double-acting actuator HJV consists of a rod 1 with a gripping device, a drive chain 2 and a lever lever control 3 of the gripping device. On the rod are mounted the rails 4 which are engaged with the drive chain 2, the rollers 5 for rolling the rod along the driving lines 6, the gripping device in the form of stops 7-10 intended to directly affect the trolley, the control of the bar Tl, ti switching switching. stops, switching strips 12, springs 13, St. -. interconnected control 11 and switching 12 strips, levers 14 and clamps 15.

The switching of the stops 7, 8 or 9, .10 (each stop is retracted by the force of the control bar 11, is articulated with the aid of a counterweight or spring after it is released by the rail 11) while the rod is moving (using the stops 16) fixed to the lever lever (control themes 3 s. electromagnet 17, activated by a specific cycle.

The pusher of the two-sided action works in the same way (both in one and in the other direction) and can tighten or push both one or several trolleys simultaneously. .

The initial position of the stops: the stops 7 and 10 are cocked, the stops “and 9 are recessed.

When performing the tightening operation, the transfer of the stops is not performed. The pusher extends to a certain length beyond the limits of the electric transfer trolley in the desired direction, the support 7 (10 passes under the support of the car; (7), the races laid on the opposite rod of the rod, do not allow the trolley to roll out of the truck,

To push the trolleys, it is necessary to change the position of the pair of lugs located on the side of the rod into which the pushing is performed, and at the end of the pushing cycle, the stops return to their original position. The switching of the stops is carried out as follows.

 Before the boom begins to move, the electromagnet 17 is turned on, which with the aid of a hitch control system. 3 places the stop 16 on the path of the lever 14. When the push rod moves, the protrusion of the lever 14 rests on the stop 16 and the lever 14 rotates around its axis. by him

0, the switching strap 12 moves along the movement of the rod and is fixed at the end of the stroke by the latch 15. Through one of the springs 13, the force from the switching strap 12 is transmitted to the control 5 of the strap D.1, and the latter moves simultaneously with the strap 12. stops 7-8 (9-10). If during switching, the stop 7 (10) is affected by

The Q stop of the car and cannot be recessed at the moment of switching, then the bar 12, moving, will reduce the spring 13, which, after releasing the bar, 7 (10) will move the bar 11

c and will transfer the boom stops.

The return of the stops to the initial position is similar.

The application of the proposed double-acting push rod on the electric transfer trolley makes it possible to operate without an operator, and the economic effect (for example, for a brick factory with a capacity of 50 ml bricks per year, where

A calllera electric transmission carts operating in three shifts is 18 thousand rubles per year.
