The specific meaning of the above terms in the present utility model can be understood by those of ordinary skill in the art according to the specific circumstances.

As shown in fig. 1 and 2, the weight type mechanical automatic grabbing beam of the utility model comprises a beam body 1, a grabbing Liang Diaogou, a transmission connecting rod 3, a diagonal draw bar 4, a swinging rod 5 and a weight 6.

Specifically, the beam body 1 is horizontally erected in the gate slot 7 and is formed by welding a pair of channel steel slots in a back-to-back manner, and guide mechanisms 8 which move up and down along the gate slot 7 are arranged at two ends of the beam body 1.

The two groups of the grippers Liang Diaogou are two groups of the grippers Liang Diaogou, and the two groups of the grippers Liang Diaogou are symmetrically arranged on the beam body 1 by taking the central line of the length direction of the beam body 1 as a symmetrical axis; the upper ends of the two grab beam lifting hooks 2 are hinged to the beam body 1 through a rotating shaft 9, so that the hook openings of the two grab beam lifting hooks 2 are guaranteed to rotate back to back and opposite or opposite directions, and the hooking or unhooking actions of the grab beam lifting hooks 2 are completed; in addition, the upper end of each grab beam hook 2 is also provided with a horizontal balancing weight 10 which is vertical to the axis of the rotating shaft 9 in a horizontally outward extending manner.

The transmission connecting rod 3 is composed of a central rotating block 3.1 positioned at the center line of the beam body 1 and a pair of connecting rods 3.2 hinged on two rotating ends of the central rotating block 3.1, the outer ends of the two connecting rods 3.2 (namely, the ends far away from the central rotating block 3.1) are respectively hinged on the grabbing beam lifting hooks 2 on two sides, so that the two grabbing beam lifting hooks 2 are connected into a whole through the transmission connecting rod 3, and when one grabbing beam lifting hook 2 rotates, the other grabbing beam lifting hook 2 is driven to rotate along with the transmission connecting rod 3, and synchronous opposite or reverse rotation of the two grabbing beam lifting hooks 2 is realized.

The inclined pull rods 4 are two groups which are symmetrically arranged, the inclined lower ends of the two inclined pull rods 4 are respectively hinged to the two rotating shafts 9, and the inclined upper ends of the two inclined pull rods are hinged into a whole through a hanging plate 11, so that the two inclined pull rods 4 and the beam body 1 are jointly surrounded to form a stable triangle structure; in addition, a hanging hole 12 is further formed in the hanging plate 11, so that the hanging plate 11 can be connected with lifting equipment in the gate slot 7 through the hanging hole 12, the hanging plate 11 is easily pulled through the lifting equipment, and the beam body 1 can stably translate up and down in the gate slot 7 under the guiding action of the guiding mechanism 8.

The swing rod 5 is located on the grabbing beam lifting hook 2 on one side, specifically, one end of the swing rod 5 is hinged on the horizontal balancing weight 10 on one side through a hinge shaft 13 parallel to the rotating shaft 9, and the swing rod 5 passes through the two channel steel of the beam body 1 obliquely upwards, so that the end, far away from the hinge shaft 13, can swing left and right above the beam body 1.

The heavy hammer 6 is fixedly connected to the end, far away from the hinge shaft 13, of the swing rod 5, namely, the heavy hammer 6 is fixedly connected to the swing rod 5 extending out of the upper part of the beam body 1, so that the heavy hammer 6 can move left and right along with the swing rod 5 above the beam body 1; at this time, since the grab beam hook 2 on one side is connected with the heavy weight 6 through the swing rod 5, the balancing weight 14 (as shown in fig. 3) is further fixedly connected to the outer end of the horizontal balancing weight 10 of the grab beam hook 2 on the other side far away from the heavy weight 6, and the balancing weight 14 is used for balancing the rotating force of the grab beam hooks 2 on both sides, so that the rotating force of the two groups of grabbers Liang Diaogou 2 is consistent when the hooking or unhooking actions are completed.

Of course, because the moment from the heavy hammer 6 to the rotating shaft 9 at the upper end of the grab beam lifting hook 2 at the connecting side is shortened, the weight of the heavy hammer 6 can be effectively reduced, and the heavy hammer 6 is convenient for operators to move; meanwhile, as the heavy hammer 6 is connected to the grab beam lifting hook 2 at one side, the crawling distance of the heavy hammer 6 on the beam body 1 can be effectively shortened when an operator moves the heavy hammer 6, and the operation risk of moving the heavy hammer 6 by the operator is reduced. In addition, since the weight of the heavy hammer 6 is reduced, a traction rope can be connected to the heavy hammer 6, so that an operator can directly pull the heavy hammer 6 to swing below the beam body 1 through the traction rope without climbing the beam body 1.

The unhooking and hooking action principle of the utility model is as follows:

the action of the hook: firstly, moving the heavy hammer 6 to the left to clamp the heavy hammer 6 on the beam body 1, wherein the heavy hammer 6 can apply downward rotation force to the horizontal balancing weight 10 under the action of self gravity at the moment, so that the grab beam lifting hook 2 has inward rotation force, and meanwhile, the grab Liang Diaogou 2 can continuously apply vertical downward force under the action of self gravity, so that the inward rotation force applied by the heavy hammer 6 to the grab beam lifting hook 2 is counteracted; at this time, the beam body 1 gradually descends along the gate slot 7, the lower end of the grab beam lifting hook 2 can prop against the gate lifting shaft, the self gravity of the grab Liang Diaogou is transmitted to the gate lifting shaft, and the reaction force of the gate lifting shaft forces the grab Liang Diaogou to rotate and deflect inwards; along with the continuous descent of the beam body 1, the hook mouth at the lower part of the grabbing beam lifting hook 2 moves to the lower part of the gate lifting shaft, and at the moment, the grabbing Liang Diaogou 2 can be restored to be in a vertical state again under the action of self gravity to collide with the gate lifting shaft, so that the hooking action is completed.

After the hooking action is completed, the heavy hammer 6 is moved to the right side, at this time, the heavy hammer 6 swings to the right side of the grab beam lifting hook 2, and an upward rotating force is applied to the horizontal balancing weight 10, so that an outward rotating force is continuously applied to the grab beam lifting hook 2, and simultaneously, the vertical downward dead weight load of a gate lifting shaft and a gate on the grab beam lifting hook 2 is matched, so that the grab beam lifting hook 2 continuously keeps the hooking action.

Unhooking action: firstly, the grab Liang Diaogou 2 hangs a gate hanging shaft and a gate to move downwards, when the gate stops descending, the beam body 1 continues to drive the grab Liang Diaogou to move downwards, so that the grab Liang Diaogou is separated from the gate hanging shaft, at the moment, the heavy hammer 6 is moved leftwards, the heavy hammer 6 is separated from a blocking block above the beam body 1 and continuously rotates to be vertically downwards, so that a larger downward rotating force is applied to the horizontal balancing weight 10, the downward rotating force of the horizontal balancing weight 10 can overcome the self gravity of the grab beam hanging hook 2, the grab Liang Diaogou 2 rotates inwards to deflect, the unhooking action is completed, and the beam body 1 can be lifted around the gate hanging shaft without being blocked and hung with the gate hanging shaft.
