Technical Field

The invention relates to the field of gantry machines, in particular to a gantry machine folding mechanism.

Background

A gantry machine is a common industrial device, and generally includes a horizontally disposed beam and columns disposed on two sides of the beam. For example, chinese patent with publication number "CN 207015317U" discloses a gantry mechanism. The gantry mechanism is a device for cleaning automobiles. In the furniture processing industry, however, a gantry is often used to transport the sheet material. A sliding mechanism and a lifting mechanism are installed on a cross beam of the gantry machine in the furniture industry, and the sliding mechanism enables the lifting mechanism to move up and down along the vertical direction. The bottom of the lifting mechanism is provided with a grabbing mechanism for grabbing the plate.

When the gantry machine is used, the plate is grabbed through the grabbing mechanism, and then the plate is lifted through the lifting mechanism. The traditional lifting mechanism is generally matched with a gear and a rack, and then the gear is driven by a motor to rotate, so that the rack is driven to move up and down, and finally the grabbing mechanism and the plate are driven to move up and down. However, the size of the gantry is relatively high, and the rack moves upwards when the lifting mechanism is used, so that certain requirements are imposed on the height of a factory building, and the gantry cannot be normally used when the height of the factory building is not enough. Also at present through changing the rack into flexible steel band, but when utilizing the steel band to carry out panel, because the flexible characteristic of steel band, panel can rock in the midair, is unfavorable for the transport of panel, and this problem needs to be solved urgently.

Disclosure of Invention

The invention aims to provide a gantry crane folding mechanism which has the characteristic of preventing a grabbing mechanism from shaking when a steel belt is used for lifting a plate.

The technical purpose of the invention is realized by the following technical scheme: the utility model provides a portal machine folding mechanism, includes first linking arm and the second linking arm that length equals, the one end and the hoist mechanism of first linking arm rotate to be connected, and the other end rotates with the second linking arm to be connected, the tip that first linking arm was kept away from to the second linking arm rotates with snatching the mechanism and is connected, and the hoist mechanism is gone up to rotate and is connected with first bracing piece, the other end and the second linking arm of first bracing piece rotate to be connected, first bracing piece is parallel with first linking arm, the tip of first linking arm and second linking arm is provided with makes the synchronous pivoted synchronizer of first linking arm and second linking arm.

By adopting the technical scheme, the steel belt naturally sags in normal use, the steel belt, the first connecting arm and the second connecting arm form an isosceles triangle, when the steel belt drives the grabbing mechanism to move upwards, the first connecting arm is rotationally connected with the second connecting arm through the synchronizing device, so that the first connecting arm rotates and the second connecting arm rotates at the same speed, the steel belt, the first connecting arm and the second connecting arm always keep the isosceles triangle state, and because the two ends of the first supporting rod are rotationally connected with the lifting mechanism and the second connecting arm respectively and the first supporting rod is parallel to the first connecting arm, when the steel belt drives the grabbing mechanism to move upwards and downwards, the first connecting arm and the second connecting arm cannot swing integrally, so that the grabbing mechanism can move vertically when moving upwards and downwards, the grabbing mechanism is prevented from shaking, and the carrying work is more stable, the working efficiency is ensured.

Preferably, the device further comprises a second supporting rod, one end of the second supporting rod is rotatably connected with the grabbing mechanism, the other end of the second supporting rod is rotatably connected with the first connecting arm, and the second supporting rod is parallel to the first connecting arm.

Through adopting above-mentioned technical scheme, the second bracing piece can further play the supporting role to first linking arm and second linking arm, and through the cooperation of first bracing piece and second bracing piece, it is more stable when making first linking arm and second linking arm rotate, and then can further guarantee to snatch when mechanism removes and follow linear motion steadily.

Preferably, the number of the first supporting rods is two, and the two first supporting rods are respectively connected to two sides of the second connecting arm in the width direction in a rotating mode.

Through adopting above-mentioned technical scheme, avoid single first bracing piece's supporting capacity not enough, make the atress more even on the second linking arm simultaneously, help equipment steady operation.

Preferably, the number of the second support rods is two, and the two second support rods are respectively and rotatably connected to two sides of the second connecting arm in the width direction.

Through adopting above-mentioned technical scheme, avoid the support ability of single second bracing piece not enough, make simultaneously on the first connecting arm atress more even, help equipment steady operation.

Preferably, the synchronizer comprises a shell arranged at the joint of the first connecting arm and the second connecting arm, the shell is rotatably connected with a first rotating shaft and a second rotating shaft, the first rotating shaft is fixedly connected with the first connecting arm, the first rotating shaft is fixedly connected with a first gear, the second rotating shaft is fixedly connected with a second connecting arm, the second rotating shaft is fixedly connected with a second gear, and the first gear is meshed with the second gear.

Through adopting above-mentioned technical scheme, first linking arm, can't take place relative rotation between first pivot and the first gear three, it is same, the second linking arm, can't take place relative rotation between second pivot and the second gear three, again because first gear and second gear meshing, therefore the second linking arm is when rotating, cooperation through first gear and second gear can drive first linking arm and rotate simultaneously, and both pivoted rates are the same, both pivoted opposite directions simultaneously, finally reach and make first linking arm and the synchronous pivoted purpose of second linking arm.

Preferably, the cross section of the housing is C-shaped, the housing is open to the first and second connecting arms, and the top and bottom of the housing are open.

Through adopting above-mentioned technical scheme, the trilateral opening of casing is convenient for the rotation of first linking arm and second linking arm, and the casing plays the guard action to the inside first gear of synchronizer and second gear simultaneously.

Preferably, the top and the bottom of the housing are respectively provided with a transparent cover plate, and one side of the housing close to the first gear and the second gear is also provided with a transparent cover plate.

Through adopting above-mentioned technical scheme, transparent cover can play dustproof effect, reduces the dust that gets into the casing inside, and then prevents that first gear and second gear from breaking down because of the interference of dust, and the user can follow the inside condition of casing in the transparent cover simultaneously, and then is convenient for inspect synchronizer.

Preferably, an oil hole is formed in the side surface of the housing through the side surface of the housing and is close to the space between the first gear and the second gear.

Through adopting above-mentioned technical scheme, the staff of being convenient for injects lubricating oil in to the casing through the oil filler hole, makes first gear and second gear can normal operating, is convenient for maintain.

In conclusion, the invention has the following beneficial effects: when making and snatching the mechanism and reciprocating under the drive of steel band, snatch the mechanism and can reciprocate along the straight line, avoid snatching the mechanism and produce in the use and rock, improved work efficiency, the operation is stable simultaneously, and convenient the maintenance is maintained conveniently.
