Description

Hook type mechanical automatic grabbing beam

Technical Field

The utility model relates to a mechanical equipment that is used for power station gate or trash rack to open and close, concretely relates to automatic roof beam of grabbing of couple formula machinery.

Background

In hydropower station engineering, the opening and closing of a porous gate and a trash rack are usually completed by adopting a movable hoist to carry an automatic grabbing beam, the common automatic grabbing beam comprises a hydraulic automatic grabbing beam and a mechanical automatic grabbing beam, and the mechanical automatic grabbing beam is mostly in a heavy hammer hook type. In the prior art, a heavy hammer hook type mechanical automatic grabbing beam uses heavy hammer gravity and drives a hook to complete hooking and unhooking actions through a multi-link mechanism, when the distance between a gate or a trash rack lifting point is large, the corresponding length of a connecting rod is very long, the self weight of the connecting rod is also large, and the situation of blocking of the link mechanism is often caused due to limited heavy hammer gravity, so that the grabbing beam cannot be normally hooked and unhooked, repeated reciprocating operation is required, and the working efficiency is influenced.

Disclosure of Invention

Based on the problem that above-mentioned prior art exists, the utility model aims at designing a structure is simpler moves more reliable couple formula machinery and grabs the roof beam automatically. The utility model aims at realizing through the following technical scheme: the utility model provides a couple mechanical automatic beam of grabbing, is different with prior art, including leading guide slider 1, side guide wheel 2, uide pin 3, supporting seat 4, roof beam body 5, couple 6 and couple shrouding 7, leading

guide slider

1 and 2 sets of fixed mounting at the both ends of roof beam body 5 of side guide wheel 2 respectively, 3 fixed mounting of uide pin on the lower bottom surface of roof beam body 5, supporting seat 4 for the bolted connection at 3 tops of uide pin, couple 6 articulated with roof beam body 5 through hanging the axle, 7 one end of couple shrouding articulate at 6 inboards of couple, the other end stretches out the gib head of couple 6. Compare the automatic roof beam of grabbing of prior art's couple formula machinery, the utility model discloses save weight and multi-link mechanism, the simple action is more reliable more of structure.

The utility model discloses automatic roof beam of grabbing of couple formula machinery, couple 6 adopt thickness 40mm steel sheet cutting to make, the bottom surface is 45 inclined planes, its focus is located upper portion lifting eye center and lower part hanging shaft groove central line.

The utility model discloses automatic roof beam of grabbing of couple formula machinery, its beneficial effect lies in: the hook has the advantages that a heavy hammer and a multi-link mechanism are omitted, the problem that the hook cannot be normally hung and unhooked due to the blocking of the connecting rods is avoided, the structure is simple, the action is reliable, the working efficiency is improved, and the hook has wide practicability.

Detailed Description

Fig. 1 shows the utility model provides a, including main direction slider 1, side guide wheel 2, uide pin 3, supporting seat 4, roof beam body 5, couple 6 and couple shrouding 7, main direction slider 1 and side guide wheel 2 each 2 sets of fixed mounting at the both ends of

roof beam body

5, 3 fixed mounting of uide pin on the lower bottom surface of roof beam body 5, supporting seat 4 with bolted connection at 3 tops of uide pin, couple 6 through hanging axle and roof beam body 5 articulated, 7 one end of couple shrouding articulate at 6 inboards of couple, the other end stretches out the gib head of couple 6. Compare the automatic roof beam of grabbing of prior art's couple formula machinery, the utility model discloses weight and multi-link mechanism have been saved.

Furthermore, as shown in fig. 1, in the first embodiment of the present invention, the hook 6 is made of a steel plate with a thickness of 40mm by cutting, the bottom surface is a 45 ° inclined plane, and the center of gravity is located on the connection line between the center of the upper hanging hole and the center of the lower hanging shaft groove.

The embodiment of the utility model provides a couple process main step schematic diagram is shown in fig. 2 to fig. 5, and it needs to be noted that, the couple in-process, 4 bolted connections are used at 3 tops of uide pin for the supporting seat:

as shown in fig. 2, as the beam body 5 descends, the guide pin 3 firstly contacts with the guide cylinder on the gate or the trash rack and starts to descend continuously along the guide cylinder;

as shown in fig. 3, as the beam body 5 descends, the bottom slope of the hook 6 starts from the contact of the hanging shaft on the gate or trash rack, and the hook 6 is deflected by the slope;

as shown in fig. 4, as the beam body 5 descends, the hanging shaft on the gate or trash rack goes over the inclined plane at the bottom of the hook 6 and contacts the hook closing plate 7;

as shown in fig. 5, the upper plane of the guide cylinder on the gate or trash rack contacts with the support seat 4, the beam body 5 does not descend any more, the hanging shaft on the gate or trash rack is just positioned in the gap between the hook closing plate 7 and the hook head of the hook 6, the hook 6 deflects under the action of self gravity to be right, the hanging shaft is retracted into the hook, and then the grabbing beam is lifted to complete the hook action.

The embodiment of the utility model provides an unhook process main step schematic diagram is shown in fig. 6 to fig. 9, and it should be noted equally, before the unhook process, demolish supporting seat 4 from 3 tops of uide pin earlier:

as shown in fig. 6, the beam body 5 can be further descended due to the removal of the supporting base 4, and the hanging shaft on the gate or the trash rack is contacted with and pushed up by the hook closing plate 7;

as shown in fig. 7, the beam body 5 continues to descend, and the hanging shaft on the gate or trash rack pushes the hook sealing plate 7 up to the inclined surface on the hook 6 and deflects the hook 6;

as shown in fig. 8, the upper plane of the guide cylinder on the gate or the trash rack is in contact with the top plane of the guide pin 3, the beam body 5 does not descend any more, at this time, the hanging shaft on the gate or the trash rack is completely separated from the hook sealing plate 7 and the hook groove, and the hook sealing plate 7 falls onto the hook head of the hook 6 under the action of self gravity;

as shown in fig. 9, the beam 5 starts to lift up, the hook 6 deflects back to be positive under the self gravity, the hook sealing plate 7 covers the hook groove of the hook 6, and the hanging shaft on the gate or the trash rack descends along the hook sealing plate 7 to complete unhooking.
