Description

Technical Field

[0001] The invention relates to the technical field of slatted floor processing, in particular to a forward vehicle used for manufacturing concrete slatted floor. Background Art

[0002] In order to keep the pig house clean and facilitate the automatic cleaning of pig manure, many modern large-scale pig farms generally use concrete slatted floors to build pig houses. The slatted floors are produced using molds. When processing the slatted floors, the slatted floor mold must first be placed on a vibration table, and then a steel mesh is placed in the mold body, filled with concrete, and the vibration table is turned on for vibration. After the vibration is dense, the upper part is smoothed, and then the mold is lifted as a whole by a lifting mechanism, and after the mold is flipped by a flipping mechanism, the flipped mold is moved down to the pallet by the lifting mechanism for demolding, and finally the processed slatted floor is placed on the pallet to complete the operation.

[0003] In the existing concrete slatted floor manufacturing device, the lifting mechanism for lifting the mold and the turning mechanism generally adopts a winch. The winch has the following shortcomings in the process of moving the turned mold down to the vibration table: when the slatted floor mold needs to be demolded, the mold is placed on the vibration table after the rope is released for a certain distance. However, the winch cannot stop working automatically, but continues to rotate and release the rope. When the wire rope is fully released and the motor of the winch is still rotating, the wire rope will be rewound on the drum, and finally the mold will be lifted off the vibration table, which brings inconvenience to the demolding work, low working efficiency, and easy damage to the equipment.

[0026] A hydraulic propulsion mechanism is installed on the upper beam 3, and the hydraulic propulsion mechanism includes a propulsion frame and a hydraulic cylinder 5. The propulsion frame includes a connecting body 6. Two slots 7 are symmetrically installed on the top of the connecting body 6. An inclined iron 8 is movably inserted in the slot 7.

The slideway 11 is arranged along the length direction of the upper beam 3, and the propulsion wheel 9 rolls in the slideway 11; the hydraulic cylinder 5 is arranged along the length direction of the upper beam 3, and the working stroke of the hydraulic cylinder 5 is consistent with the wire rope 16 The descending distance is consistent. When the hydraulic cylinder 5 is not working, the slide 11 and the hydraulic cylinder 5 are respectively located at the left and right halves of the upper beam 3. One end of the fixed seat of the hydraulic cylinder 5 is hinged on the upper beam 3. One end of the piston rod of the hydraulic cylinder 5 is hinged on the connecting body 6 of the propulsion frame.

[0027] A steel wire rope 16 is wound around each inclined iron 8, and the steel wire rope 16 is fixed in the slot 7 after being wound around the inclined iron 8 (the steel wire rope 16 is clamped between the inclined iron 8 and the slot 7), one end of the steel wire rope 16 passes around the first right guide wheel 13, hangs down and is fixedly connected to a rope clamp 17, and the other end of the steel wire rope 16 passes around the second right guide wheel 14 and the corresponding left guide wheel 12 in turn, hangs down and is fixedly connected to the rope clamp 17;

[0028] The two ends of the upper beam 3 are respectively fixedly connected to the gantry frames 4 on both sides, and columns 18 are respectively fixedly installed in the gantry frames 4 on both sides.

[0029] The propulsion frame moves along the slideway 11 through the propulsion wheel 9 under the action of the hydraulic cylinder 5, and the inclined iron 8 moves with the propulsion frame. When the hydraulic cylinder 5 is extended, the propulsion frame moves to the left, and the inclined iron 8 drives the fixed part of the wire rope 16 to move to the left, then both ends of the wire rope 16 move upward, which can drive the crossbeam 20 to move upward;

[0030] The slot 7 at the top of the connecting body 6 is trapezoidal, and the profile of the oblique iron 8 matches the shape of the slot 7, and the oblique iron 8 is wedged into the slot 7.

[0031] Two pairs of propulsion wheels 9 are rotatably connected on both sides of the propulsion frame, so that the propulsion process is more stable and the lifting stability is improved.

[0032] The bottom of the four corners of the upper beam 3 are respectively fixedly connected with connecting plates 21, and the upper beam 3 is fixedly connected to the door-type frame 4 through the connecting plates 21.

[0035] When the slatted floor to be treated is smoothed, the first reduction motor 25 drives the active sprocket to rotate, and the active sprocket drives the passive sprocket to rotate through the chain, so that the pulley 24 moves along the beam 20; the second reduction motor 28 rotates to rotate the smoothing plate 29 to perform smoothing work.

[0036] The flip mechanism includes a hanging rod 30 fixedly connected to both sides of the crossbeam 20, and a pull plate 31 is fixedly connected to the lower end of the hanging rod 30.

[0037] When the flipping mechanism is in use, the crossbeam 20 is moved and the clamp 33 is clamped into the slatted floor mold body. When vibration treatment is required, the slatted floor mold body is placed on the vibration table. After the mold body is placed on the vibration table, the crossbeam 20 continues to move downward for a certain distance. At this time, the first coupling 32 and the clamp 33 remain stationary with the mold body, and the second coupling 35 moves downward with the hanging rod 30 and the motor mounting plate 34. The flipping drive mechanism will not participate in the vibration. When the vibration processing is completed, the crossbeam 20 is lifted up, which will drive the hanging rod 30 and the second coupling 35. The second coupling 35 will re-engage the first coupling 32. When the mold body is completely separated from the vibration table, the flipping drive mechanism is used to flip the mold body.

[0038] When the present invention is in use, the frame can walk along the ground track through the walking ground beam 1, which can ensure the reciprocating operation of the frame. The piston rod of the hydraulic cylinder 5 is extended or not, and the propulsion frame is moved along the slide 11, which can realize the extension and contraction of the wire rope 16, and the cross beam 20 can be lifted and lowered, driving the rise and fall of the trowel device and the turning mechanism. A suitable hydraulic cylinder 5 is selected to make the working stroke of the hydraulic cylinder 5 consistent with the distance that the wire rope 16 needs to descend. When the wire rope 16 descends to the required position, the present invention can automatically stop descending. Compared with the prior art, the present invention does not need to manually control the winch switch, and can stop when the slatted floor mold body is in place.
