Description

Technical Field

[0001] The utility model relates to the technical field of three-dimensional forklifts, in particular to a three-dimensional forklift capable of vertically turning over materials. Background Art

[0002] The three-dimensional forklift is an important part of the production line equipment that allows customers to quickly and automatically remove materials from the quenching furnace, place them in the quenching pool, and then transfer them to the tempering furnace / material rack and other process positions.

[0003] Typically, 3D forklifts move materials horizontally, transporting them to various process locations. However, for materials such as hydraulic cylinders, which require strict deformation control and require simultaneous entry and exit of materials into the quenching tank, the process requires them to be transported upright. Existing 3D forklifts require fastening devices to position the materials before transporting them upright. However, this poses a challenge for stability when transporting materials upright into and out of tempering furnaces and racks. Utility Model Content

[0004] The technical problem to be solved by the present invention is to overcome the existing defects and provide a three-dimensional forklift capable of vertically turning materials, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above-mentioned purpose, the utility model discloses a three-dimensional forklift that can flip materials vertically. The technical solution adopted is that it includes a forklift body, a lifting rod is slidably connected to the forklift body, a lifting chain is connected to the lifting rod, the lifting rod is connected to the fork tine through a material fork connecting frame, the fork tine is movable, the material fork connecting frame is connected to a hinged plate, the movable fork tine is hinged on the hinged plate, and a retracting mechanism is provided on the forklift body, the retracting mechanism is connected to the movable fork tine, and the rotation of the movable fork tine can be controlled by the retracting mechanism so that it can be converted between horizontal and vertical states; the movable fork tine is connected to a material tray, and the material tray includes a baffle, which is arranged perpendicular to the movable fork tine, and the baffle can carry the material when the movable fork tine is in a vertical state.

[0006] As a preferred technical solution of the present invention, the movable fork tine is hinged to the hinge plate via a pin.

[0007] As a preferred technical solution of the present invention, the retractable mechanism includes a traction rope and a hydraulic cylinder. The forklift body is provided with an electric retractable rope roller, the traction rope is wound around the electric retractable rope roller, and the free end of the traction rope is connected to the movable fork tine. When the movable fork tine needs to be turned from a horizontal state to a vertical state, the traction rope can be retracted by the electric retractable rope roller to apply traction to the movable fork tine. The fixed end of the hydraulic cylinder is fixedly mounted on the material fork connecting frame, and the hydraulic cylinder and the material fork connecting frame are perpendicular, and the telescopic end extends toward the movable fork tine. When the movable fork tine needs to be turned from a vertical state to a horizontal state, the electric retractable rope roller releases the traction rope, and at the same time the hydraulic cylinder extends to apply thrust to the material or the movable fork tine, causing it to tilt, and then gradually reach a horizontal state due to the material's own gravity.

[0008] As an optimal technical solution of the present invention, the material tray and the baffle form an L-shaped structure, and there is a fork tine groove on the bottom surface of the material tray. The setting direction and opening direction of the fork tine groove are opposite to the movable fork tine, so that the movable fork tine can enter the fork tine groove. When the movable fork tine rotates the material tray, the fork tine groove can prevent excessive relative sliding between the material tray and the movable fork tine, thereby maintaining the stability of the material and ensuring production safety.

[0009] As a preferred technical solution of the present invention, the material tray is a hollow plate, and the quenching liquid in the quenching pool can pass through the hollow holes to contact the material on the material tray.

[0010] As a preferred technical solution of the present invention, the bottom surface of the tray has legs, which can maintain the level of the tray together with the fork grooves when the tray is placed in a quenching furnace, a material rack or a tempering furnace.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention sets the fork tines as hinged movable fork tines and provides a retracting and extending mechanism, which can transform the movable fork tines between horizontal-inclined-vertical states as needed, thereby meeting the needs of horizontal entry and exit of materials in the quenching pool, and can turn to a vertical state when simultaneous quenching of the inside and outside is required, so that the materials enter the quenching pool vertically, meeting the needs of different quenching processes; and the baffle on the material rack can support the bottom surface of the material when the movable fork tines carrying the loaded materials turn to a vertical state; further, the bottom surface of the material tray is provided with fork tine grooves, which can maintain a stable connection between the material tray and the movable fork tines during the state conversion process after the fork tines of the forklift are inserted, thereby preventing the material from falling and ensuring production safety.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1

[0020] like Figures 1 to 6 As shown, the utility model discloses a three-dimensional forklift that can vertically flip materials. The technical solution adopted is that it includes a forklift body 1, a vertically arranged directional slide on the forklift body 1, a lifting rod 2 is slidably connected in the directional slide, and the lifting rod 2 is connected to a lifting chain 3. The lifting chain 3 is connected to the lifting system of the forklift body 1, and the lifting and lowering of the lifting rod 2 can be controlled by the lifting system.

[0021] The lower end of the lifting rod 2 is connected to the material fork connecting frame 4. In order to be compatible with different process requirements, the material fork adopts movable fork teeth 5. Therefore, hinge plates 401 are set on both sides of the end surface of the material fork connecting frame 4 facing the material fork. Hinge holes are opened on the hinge plates 401. Pin shafts 6 are set on both sides of the movable fork teeth 5. The pin shafts 6 are located in the middle of both sides of the movable fork teeth 5, dividing the movable fork teeth 5 into a shorter section and a longer section. When the movable fork teeth 5 are in a horizontal state, the end of the shorter section is connected to the bottom surface of the material fork connecting frame 4, thereby preventing The working end of the movable fork 5 is prevented from continuing to sink; in order to be able to control the rotation of the movable fork 5, a longer side section is provided with a traction arm extending outward, and a traction rope 11 is connected to the traction arm. The traction arm is provided to move the connection point of the traction rope 11 outward to prevent the traction rope 11 from interfering with the load. An electric rope retracting roller is connected to the forklift body 1. This embodiment adopts an electric hoist, and the lifting wire rope of the electric hoist is the traction rope 11. The movable fork 5 can be converted from horizontal to vertical by rewinding the traction rope 11 by the electric hoist.

[0022] In order to prevent the movable fork 5 from continuing to flip over under the action of gravity of the loaded material 10 after the movable fork 5 reaches the vertical state, a stop plate is set under the hinge plate 401. After the movable fork 5 reaches the vertical state, the shorter section is connected to the stop plate and cannot continue to flip over.

[0023] Taking into account that when the movable fork tine 5 is in a vertical state, only releasing the traction rope 11 cannot provide a lateral thrust, and thus cannot break the stability of the movable fork tine 5 in the vertical state, a horizontal hydraulic cylinder 13 is provided on the material fork connecting frame 4, and the hydraulic cylinder 13 and the movable fork tine 5 are relatively arranged. When it is necessary to turn the movable fork tine 5 from a vertical state to a horizontal state, not only the traction rope 11 is slowly released, but also the telescopic rod of the hydraulic cylinder 13 is pushed out at the same time to apply a lateral thrust to the material 10 or the movable fork tine 5, thereby breaking the stability of the movable fork tine 5, and continuing to release the traction rope 11 can gradually turn the movable fork tine 5 to a horizontal state.

[0024] In order to maintain the stability of the material 10 during the turning process of the movable fork 5, a material tray 7 is introduced. Figure 3 、 Figure 4As shown, the feed tray 7 is a hollow plate with raised edges around it. A baffle 8 is positioned near one end of the lifting rod 2. The baffle 8 and the feed tray 7 form an L-shaped structure. After the movable tines 5 drive the feed tray 7 to flip to a vertical position, the baffle 8 provides support for the material 10. To strengthen the bond between the baffle 8 and the feed tray 7, reinforcing ribs are provided between the baffle 8 and the feed tray 7. To prevent excessive relative sliding between the movable tines 5 and the feed tray 7 during flipping, or even the feed tray 7 detaching from the movable tines 5, a tine groove 9 is provided on the bottom surface of the feed tray 7. The tine groove 9 is positioned opposite the movable tines 5, and the opening of the tine groove 9 faces the movable tines 5, allowing the movable tines 5 to be inserted into the tine groove 9. Due to the presence of the tine groove 9, to maintain the levelness of the feed tray 7 when storing the material 10, a support leg 14 is provided on the bottom surface of the feed tray 7. The bottom surface of the support leg 14 is flush with the bottom surface of the tine groove 9.

[0025] The working principle of this utility model:

[0026] The hydraulic cylinder (material 10) is loaded on the material tray 7. After the material is heated in the quenching furnace, the furnace door of the quenching furnace is opened. The staff starts the forklift body 1 and comes to the furnace door. In the initial state, the movable fork tine 5 is in a horizontal state. The staff drives the forklift body 1, aligns the movable fork tine 5 with the fork tine groove 9 of the material tray 7 and inserts it into the fork tine groove 9. The material fork is lifted to lift the material tray 7. The forklift is driven to the quenching pool 12. Figure 5 As shown, the electric hoist is started, the traction rope 11 is wound, and the traction rope 11 pulls the movable fork 5, which drives the material tray 7 and the material 10 to rotate through the pin 6 until the movable fork 5, the material tray 7, and the material 10 rotate to a vertical state, and the material 10 sits on the baffle 8.

[0027] The lifting mechanism is controlled to lower the lifting rod 2, allowing the tray 7 and material 10 to enter the quenching tank 12, quenching both the inner and outer walls of the material 10 simultaneously. The quenching liquid passes through the hollow holes of the tray 7 and contacts the material 10. To ensure more complete contact between the quenching liquid and the material 10, a stirring fan is installed in the quenching tank 12. This stirring fan is turned on to keep the quenching liquid flowing. After quenching is completed, the lifting mechanism is controlled to raise the lifting rod 2, allowing the tray 7 and material 10 to exit the quenching tank 12.

[0028] Control the electric hoist to release the traction rope 11, and at the same time control the hydraulic cylinder 13 to push out the telescopic rod, applying thrust to the material 10 to destroy its balance, causing the movable fork 5, the material tray 7 and the baffle 8 to tilt, and gradually and slowly tend to be horizontal as the traction rope 11 is released.

[0029] The staff drives a forklift to leave the quenching tank 12 and places the material tray 7 on the material rack.

[0030] The mechanical connection involved in the present invention is a common means used by those skilled in the art, and technical inspiration can be obtained through a limited number of experiments, which belongs to common knowledge.

[0031] Components not described in detail herein are prior art.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
