Description

Technical Field

[0001] This utility model relates to the field of large-size cargo hoisting technology, and in particular to a cutting and gripping device. Background Technology

[0002] As large-sized boards, slabs have a wide range of uses, but they are not convenient to transport. Slabs are generally bundled together by stacking multiple pieces, and then stacked on the ground in an alternating horizontal and vertical manner to form a cross stack, before being transported to the designated location.

[0003] Currently, bundled slabs are generally transported using two methods: one is by hoisting the bundles with slings using lifting equipment; the other is by forklift transport. However, the sling method requires manual operation, and the bundled slabs are not only heavy but also have sharp corners, posing a certain operational hazard to manual handling. The forklift transport method requires limited forklift space, and because the bundled slabs are placed in a cross-stacking arrangement on the ground, the forklift needs to move back and forth to coordinate with the stacking direction, resulting in low work efficiency.

[0004] Therefore, it is necessary to design a cutting board gripping device for rapid gripping and hoisting of cutting boards. Utility Model Content

[0005] The purpose of this invention is to provide a cutting and gripping device that solves the above-mentioned technical problems.

[0006] Therefore, the technical solution of this utility model is as follows:

[0007] A cutting and gripping device includes a main lifting beam, an opening and closing drive mechanism, and a cutting gripper arranged sequentially from top to bottom; wherein...

[0008] The main lifting beam includes a horizontally arranged strip beam; the opening and closing drive mechanism includes a worm gear lifting mechanism, a connecting beam, and two linkage groups; the worm gear lifting mechanism is fixed to the bottom of the beam with its movable screw pointing vertically downwards, and a connecting sleeve is provided at the bottom end of the movable screw; the connecting beam is sleeved in the connecting sleeve and arranged horizontally along the length of the beam, so as to drive the connecting beam to rise and fall through the worm gear lifting mechanism; the two linkage groups are symmetrically arranged on both ends of the beam, each linkage group consists of two connecting rods, and the top ends of the two rods are hinged to the end plates of both ends of the beam through pins;

[0009] The cutting plate gripper consists of two grippers symmetrically arranged at both ends of the connecting beam. Each gripper comprises two intersecting, zigzag-shaped claws. The tops of the two claws are respectively hinged to the bottom ends of two transmission rods on the same side by pins. The intersection of the two claws is hinged to the end face of the connecting beam on the same side by pins, so that the upper parts of the two claws and the two transmission rods form a parallelogram connecting rod structure. The lower parts of the two claws are set downwards, and the bottom ends of the two claws are provided with hooks facing each other to support the bottom surface of the cutting plate to be gripped.

[0010] Furthermore, two lifting lug assemblies are symmetrically arranged at the middle of the top side of the beam, and each lifting lug assembly includes at least two lifting lugs arranged at intervals.

[0011] Furthermore, the end plates at both ends of the beam extend downward to form a connecting part, so that the top ends of the two transmission rods can be hinged to the connecting part on the same side by means of pins.

[0012] Furthermore, each claw body is composed of a first connecting rod, a second connecting rod, a third connecting rod, and a support hook that are sequentially connected and integrally formed. The second connecting rod is a horizontal rod, and the first connecting rod and the third connecting rod are connected to the two ends of the second connecting rod at an angle upward and downward, respectively. The support hook is a hook body that is angled upward and faces the second connecting rod.

[0013] Furthermore, the included angle between the first connecting rod and the second connecting rod is set to 155°, the included angle between the second connecting rod and the third connecting rod is set to 105°, the length of the second connecting rod is adapted to the width of the cutting plate, and the length of the third connecting rod is adapted to the total thickness of the stacked cutting plates corresponding to the maximum number of cutting plates to be gripped.

[0014] Furthermore, the horizontal distance between the two grippers is 1.5m to 2m.

[0015] Furthermore, multiple reinforcing rods are spaced apart between the two grippers, arranged parallel to the connecting beam, with both ends of each reinforcing rod vertically fixed to the opposite side wall of the gripper body.

[0016] Furthermore, on each gripper, a clamping plate is attached and fixed to the opposite side wall of the lower part of the two grippers.

[0017] Compared with existing technologies, this cutting and gripping device solves the problems of operational risks in the sling hoisting operation that requires manual assistance and low efficiency in forklift transportation. By designing a cutting and gripping device consisting of a main lifting beam, an opening and closing drive mechanism, and a cutting claw connected sequentially from top to bottom, this device can be directly connected to the lifting equipment to carry out cutting and lifting operations. It can not only achieve one-time gripping of bundled cutting boards, but also eliminates the need for manual assistance, resulting in high efficiency and low risk. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but the following embodiments are by no means intended to limit the present invention.

[0025] See Figure 1 and Figure 2 The cutting and gripping device includes a main lifting beam 1, an opening and closing drive mechanism 2, and a cutting claw arranged sequentially from top to bottom.

[0026] The main lifting beam 1 includes a horizontally arranged strip beam 101, which is preferably a hollow beam with a cubic structure; two lifting lug groups 102 are symmetrically arranged at the middle of the top side of the beam 101, and the two are preferably symmetrically distributed on both sides of the beam length direction, and each lifting lug group 102 consists of two spaced lifting lugs.

[0027] The opening and closing drive mechanism 2 includes a worm gear lifting mechanism 201, a connecting beam 202, and two linkage groups 203. The worm gear lifting mechanism 201 is fixed at the center of the bottom surface of the beam 101 with its movable screw pointing vertically downwards, and a connecting sleeve 204 is fixed at the bottom end of the movable screw, with a through hole opened on it along the length direction of the beam 101. The connecting beam 202 is horizontally inserted into the connecting sleeve 204 to maintain a horizontal setting along the length direction of the main lifting beam 1, and the connecting beam 202 is driven to rise and fall by the worm gear lifting mechanism 201. The two linkage groups 203 are symmetrically arranged on both ends of the main beam 1. Correspondingly, the end plates of both ends of the beam 101 extend downwards and form an inverted triangular connecting part. Each linkage group 203 includes two transmission rods, the top ends of which are hinged to the connecting part on the same side of the beam 101 by a pin.

[0028] The worm gear lifting mechanism 201 specifically includes a motor, a lead screw, and a worm. The lead screw and the worm are arranged perpendicularly and intersecting each other. The outer wall of the lead screw nut has external teeth, which can mesh with the worm to form a worm gear mechanism. The output shaft of the motor is connected to one end of the worm through a coupling. In practical applications, the motor drives the worm to rotate, thereby driving the lead screw nut to rotate. Since the position of the lead screw nut is relatively fixed, the lead screw moves along its axis under the rotation of the lead screw nut. Since the worm gear lifting mechanism 201 is set with its lead screw pointing vertically downward, when the motor rotates, the lead screw can drive the connecting beam 202 to perform lifting and lowering movements.

[0029] The advantage of the worm gear lifting mechanism 201 is that it can lock the lifting and lowering position of the connecting beam 202 through the motor, ensuring the stability of the opening and closing of the cutting claw; and, in the event of power failure or equipment failure, the goods will not fall.

[0030] Preferably, two limiting blocks are sleeved and fixed on the connecting beam 202, and the two blocks are respectively set on both sides of the connecting sleeve 204 to limit the position of the connecting sleeve 204 on the connecting beam 202.

[0031] The cutting plate gripper consists of two grippers 3, which are symmetrically arranged on both ends of the connecting beam 202. Each set of grippers consists of two intersecting zigzag claw bodies 301. The top ends of the two claw bodies 301 are respectively hinged to the bottom ends of two transmission rods on the same side by pins. The intersection of the two claw bodies 301 is hinged to the end face of the connecting beam 202 on the same side by pins, so that the upper part of the two claw bodies 301 and the two transmission rods form a parallelogram connecting rod structure. The lower part of the two claw bodies 301 is set downward, and the bottom ends of the two claw bodies are provided with hooks facing each other, so as to realize the opening and closing movement of the lower part through the up and down extension and retraction movement of the upper connecting rod structure.

[0032] In this embodiment, each claw body 301 is specifically composed of a first connecting rod, a second connecting rod, a third connecting rod and a support hook that are sequentially connected and integrally formed. The second connecting rod is a horizontal rod, and the first connecting rod and the third connecting rod are connected to the two ends of the second connecting rod in an oblique upward and oblique downward manner, respectively. The support hook is a hook head body that is obliquely upward and faces the second connecting rod.

[0033] In practical applications, the mainstream steel mill cutting machines currently cut plates in two specifications: 1.2m wide and 1.5m wide, typically bundled in groups of 15-30 plates. To improve the versatility of the gripping device and maintain stable clamping force, the angle between the first connecting rod and the second connecting rod of the claw body 301 is set to 155°, the angle between the second and third connecting rods is set to 105°, and the length of the second connecting rod is set to 0.8m. Furthermore, based on the plate widths of 1.2m and 1.5m, the length of the second connecting rod is set to 1.6m; based on the plate length typically ranging from 2.4m to 4.8m, the distance between the two sets of grippers is set to 2m; based on the single plate thickness typically ranging from 2mm to 8mm, i.e., the total thickness of the bundled plates 4 is 120mm to 300mm, the length of the third connecting rod is set to 450m to achieve the ability to grip 1-2 bundles of plates at a time.

[0034] As a preferred technical solution of this embodiment, on each gripper 3, a clamping plate 302 is attached and welded to the opposite side wall of the lower part of the two gripper bodies 301 (i.e. the third connecting rod) to increase the contact area between the gripper body 301 and the side wall of the bundled cutting plate 4, and at the same time increase the structural strength of the lower gripper body.

[0035] As another preferred technical solution of this embodiment, multiple reinforcing rods 5 are also provided at intervals between the grippers 3 on both sides, which are arranged in a manner parallel to the connecting beam 202; the two ends of each reinforcing rod 5 are vertically fixed on the opposite side wall of the gripper body 301; the arrangement of these multiple reinforcing rods 5 can not only strengthen the overall structural strength of the cutting plate gripper, but also ensure the synchronous movement of the grippers 3 on both sides, and ensure that the opening and closing actions of the grippers 3 on both sides are consistent.

[0036] See Figures 3-6 The specific usage methods of the cutting board gripping device for bundled cutting boards 4 with a width of 1.2m and 1.5m are described below.

[0037] A locking device is fitted onto the lifting lugs of the cutting board gripping device and connected to the lifting equipment. Then, the lifting equipment moves the cutting board gripping device above the four layers of bundled cutting boards to be gripped. The screw of the worm gear lifting mechanism 201 is controlled to move upwards, thereby lifting the connecting beam 202. This causes the connecting rod structure formed by the upper part of the gripper 3 and the connecting rod assembly on each side to retract upwards, driving the two claws of each gripper 3 to open relative to each other. At this time, the cutting board gripper is in an open state. The cutting board is then lowered through the device. The board gripping device places the open cutting claws on both sides of the bundled cutting board 4 to be gripped. When the board gripping device is lowered until the bottom hook of the cutting claw is below the bundled cutting board 4, the screw of the worm gear lifting mechanism 201 is controlled to descend. This causes the connecting beam 202 to lower the connecting structure formed by the upper part of the gripper 3 and the connecting rod assembly on each side, thereby driving the two claws of each gripper 3 to engage and firmly clamp the bundled cutting board 4 on both sides, thus achieving gripping.

[0038] like Figure 3 and Figure 4 The diagram shows a cutting gripper gripping a 1.5m wide cutting board. Since the cutting gripper is designed based on the dimensions of this cutting board, it can grip at least one bundle of cutting boards by contacting the sides and bottom of the bundled cutting boards 4 through the clamping plates 302 fixed inside the four grippers and the bottom hooks of the four grippers 301. This allows a lifting device to transport the bundled cutting boards 4 to a designated location. Using the method described above, the bundled cutting boards 4 can be unloaded from the cutting gripper by controlling the opening of the cutting gripper.

[0039] like Figure 5 and Figure 6 The diagram shows a cutting board gripping device gripping a 1.2m wide cutting board. During gripping, the four claws 301 will further engage according to the width of the cutting board, and use the clamping plates 302 fixed inside the four claws and the hooks at the bottom of the four claws 301 to grip the sides and bottom of the bundled cutting board 4 in a point-contact gripping manner to achieve a firm gripping. Similarly, the cutting board gripping device transports the bundled cutting board 4 with a relatively narrow width to the designated location by gripping.
