Description

Technical Field

[0001] The invention relates to the technical field of lifting equipment, and in particular to a cable roll storage area handling device. Background Art

[0002] The cable roll storage area is an area dedicated to storing and managing cable rolls, usually located in factories, warehouses, construction sites and other places. The design and management of the cable roll storage area is of great significance to ensure the safety, quality, transportation efficiency and storage space utilization of cables. The handling of cable rolls in the cable roll storage area is usually in the form of manual handling, forklift handling, lifting equipment lifting, drum car handling and conveyor belt handling. Among them, manual handling is only applicable to small and light cable rolls. Lifting equipment lifting, drum car handling and conveyor belt handling all require additional transportation lines to be built in the cable roll storage area, which is relatively costly. Therefore, forklift handling is widely used in the handling operations in the cable roll storage area due to its advantages such as simple operation, convenient and fast handling. However, there are still the following shortcomings in the process of forklift handling of cable rolls: 1. Since it is inconvenient to fix the distance between the two forks on the forklift, when forking a cable roll whose diameter or length is much larger than the distance between the two forks, the contact area of ​​the forklift is small, which makes it difficult to keep the cable roll balanced during forklift transportation and it is very easy to fall off the forklift; 2. When forking a horizontally placed cable roll, due to the influence of inertia, when the forklift brakes or turns, the cable roll is very likely to shake on the fork. Especially in the case of sudden braking or sharp turns, the cable roll is easy to roll off the fork, which poses a great safety hazard; Therefore, there is an urgent need for a cable roll storage area handling device that can overcome the above-mentioned shortcomings.

DETAILED DESCRIPTION

[0017] The technical solution of the present invention will be described below in conjunction with the drawings in the embodiments of the present invention. In the description, it should be understood that if there are terms such as "upper", "lower", "front", "back", "left", "right", etc. indicating directions or positional relationships, they only correspond to the drawings of the present invention and are for the convenience of describing the present invention, rather than indicating or implying that the device or element referred to must have a specific direction.

[0018] Please refer to the instruction manual Figure 1-6 , the present invention provides a technical solution: Embodiment 1, a cable roll storage area handling device, including a cable roll handling forklift consisting of a vehicle body 1, a lifting mechanism 2, a movable plate 3 and a fork 6, the lifting mechanism 2 is arranged at the front of the vehicle body 1, the movable plate 3 is installed on the lifting mechanism 2, and is lifted and driven by the lifting mechanism 2, two forks 6 are installed on the front surface of the movable plate 3, and a slide groove 4 is arranged along the length direction of the movable plate 3 on the lower side of the front surface of the movable plate 3, the rear ends of the two forks 6 are slidably installed in the slide groove 4, and a driving mechanism 5 for driving the two forks 6 to move synchronously toward or away from each other is arranged in the slide groove 4. Specifically, the driving mechanism 5 is used to drive the two forks 6 to move synchronously toward or away from each other. The mechanism 5 includes a bidirectional screw rod 10, a motor 11 and a mounting plate 12. The bidirectional screw rod 10 arranged along the length direction of the slide slot 4 is rotatably mounted in the slide slot 4. The rear ends of the two forks 6 located in the slide slot 4 are respectively provided with screw holes 18 threadedly connected to the two ends of the bidirectional screw rod 10. The back surface of the movable plate 3 is provided with a mounting plate 12. The mounting plate 12 is provided with a motor 11 for driving the bidirectional screw rod 10 to rotate, wherein the end of the bidirectional screw rod 10 close to the motor 11 passes through the slide slot 4, and the output end of the motor 11 is connected to the outlet end of the bidirectional screw rod 10 through a transmission gear 14 and a transmission belt 13. When carrying the cable roll, no matter whether the cable roll is placed vertically or horizontally, the driver can drive the two forks 6 to move synchronously toward or away from each other through the motor 11. If the cable roll is placed vertically, the distance between the two forks 6 is adjusted to be larger than the radius of the cable roll, and the two forks 6 are inserted from the bottom of the cable roll and lifted up to carry the vertically placed cable roll. If the cable roll is placed horizontally, the distance between the two forks 6 is adjusted to match the length of the cable roll, and the two forks 6 are inserted into the bottom of the cable roll in the cable roll. Both forks 6 are located on the inner side of the cable roll, and the horizontal and stable carrying of the cable roll can be completed. In the process of transporting the cable roll, due to the inertia of the forklift, when turning or braking, the cable roll is very likely to shake, especially when the cable roll is transported horizontally, the cable roll is very likely to roll on the fork 6, which poses a great safety hazard. In order to ensure the safety and stability of the cable roll during transportation, the upper surfaces of the front ends of the two forks 6 are provided with grooves 7 arranged along the length direction of the forks 6, and the grooves 7 are provided with a limiting mechanism 8 for blocking and limiting the cable roll. Specifically, the limiting mechanism 8 includes an electric cylinder 20, a movable rod 21 and a blocking rod 22. The groove 7 is provided with an electric cylinder 20 arranged along the length direction of the groove 7. The electric cylinder 20 is a hydraulic cylinder that can be electrically driven, which is connected to the vehicle body 1 circuit and is connected to the cab of the vehicle body 1 through the vehicle body 1. The rear end of the electric cylinder 20 is fixedly connected to the inner wall of the groove 7 near the front end of the fork 6, and the output end of the electric cylinder 20 is provided with a stop rod 22 arranged along the length direction of the groove 7, one end of the stop rod 22 is hingedly connected to the output end of the electric cylinder 20, and the upper part of the electric cylinder 20 is provided with a movable rod 21 located in the groove 7 and arranged along the length direction of the groove 7, one end of the movable rod 21 is hingedly connected to the inner wall of the groove 7 near the front end of the fork 6, and the other end of the movable rod 21 is hingedly connected to the upper part of the rod body of the stop rod 22, wherein the hinged end of the output end of the electric cylinder 20 and the stop rod 22, as well as the hinged ends at both ends of the movable rod 21 are hingedly connected through a hinge shaft, and the length of the groove 7 is greater than the sum of the minimum overall length of the electric cylinder 20 and the length of the stop rod 22; When the two forks 6 pick up the horizontally placed cable roll, the cable roll collides with the movable plate 3, and the driver controls the output end of the electric cylinder 20 to extend outward. As the electric cylinder 20 pushes the blocking rod 22, since the thrust of the electric cylinder 20 on the blocking rod 22 and the pulling force of the movable rod 21 and the blocking rod 22 are not in the same straight line, the blocking rod 22 is pushed by the electric cylinder 20 and limited by the movable rod 21 so that the blocking rod 22 can flip upward with its hinged end as the center of rotation, thereby realizing the blocking and limiting of the cable roll on the upper part of the fork 6, and preventing the cable roll from rolling off the fork 6 due to inertia.

[0019] In the second embodiment, since the two forks 6 can slide synchronously toward or away from each other, when the forks 6 are subjected to stress after carrying the cable rolls for many times, the movable connection part between the forks 6 and the slide groove 4 is easily deformed by stress, which not only affects the subsequent adjustment of the spacing between the two forks 6, but also has certain safety hazards. In order to ensure the stability of the movable connection between the two forks 6 and the slide groove 4, the slide groove 4 penetrates the movable plate 3, the rear end of the fork 6 penetrates the slide groove 4, and the folding rod 17 at its end contacts the rear surface of the movable plate 3, and the folding rod 17 and the movable plate 3 They are arranged parallel to each other, and the folding rod 17 and the fork 6 are an integrated structure. A limit block 15 is provided on the contact surface between the folding rod 17 and the movable plate 3, and a limit groove 25 arranged along the length direction of the movable plate 3 is provided on the rear surface of the movable plate 3. The contact surface between the folding rod 17 and the movable plate 3 is provided with a limit block 15 inserted into the limit groove 25 and slidably matched with the limit groove 25, and a side clamping groove 26 arranged along the length direction of the limit groove 25 is provided on the inner side wall of the limit groove 25, and an outer folding edge 16 slidably matched with the side clamping groove 26 is provided on the side of the limit block 15.

[0020] Embodiment three, when the two forks 6 are moving toward each other, in order to prevent the folding rod 17 at the rear end of the forks 6 from colliding with the lifting mechanism 2, the length of the movable plate 3 is greater than the width of the lifting mechanism 2, the middle part of the slide groove 4 is used to separate the slide groove 4 and a partition 9 corresponding to the lifting mechanism 2, the bidirectional screw rod 10 passes through the partition 9, and the threaded sections at both ends of the bidirectional screw rod 10 are respectively located on both sides of the partition 9, the length of the partition 9 is adapted to the width of the lifting mechanism 2, and the setting of the partition 9 can be used to block and limit the two forks 6 to prevent the folding rod 17 from colliding with the lifting mechanism 2 during the process of adjusting the distance between the two forks 6.

[0021] In the fourth embodiment, during the process of the electric cylinder 20 pushing the baffle rod 22 to flip, a part of the thrust applied by the electric cylinder 20 to the baffle rod 22 will act on the hinged connection between the electric cylinder 20 and the baffle rod 22, and a part of it will act on the hinged connection between the movable rod 21 and the baffle rod 22. This will cause the hinged connection to be easily subjected to force and produce loss, thereby affecting the subsequent rotation of the baffle rod 22. In order to facilitate the convenient and efficient flipping of the baffle rod 22 and reduce the wear of the hinged part, the inner wall of the groove 7 at one end close to the movable plate 3 is an inclined wall 24, and the upper end of the inclined wall 24 is inclined toward the movable plate 3. The movable end of the baffle rod 22 is provided with an inclined surface 23 parallel to the inclined wall 24. Guided by the inclined wall 24 and the inclined surface 23, the movable end of the baffle rod 22 can be quickly and conveniently tilted up, which greatly facilitates the subsequent vertical flipping of the baffle rod 22 while also reducing the force on the hinged part.

[0022] In embodiment five, when the electric cylinder 20 pushes the baffle rod 22 to flip, if the extension of the output end of the electric cylinder 20 is limited, the baffle rod 22 will flip to an inclined state with the movable end tilted toward the movable plate 3. In this case, when the cable is rolled up and the baffle rod 22 is accidentally squeezed, it is very easy to press the baffle rod 22 down into the groove 7, thereby causing damage to the hinged connection between the movable rod 21 and the baffle rod 22, and the electric cylinder 20. In order to ensure that the baffle rod 22 can flip to a vertical state or flip to an inclined state with the movable end tilted away from the front end of the fork 6, the maximum overall length of the electric cylinder 20 is not less than the length of the movable rod 21, wherein the maximum overall length of the electric cylinder 20 refers to the sum of the cylinder body of the electric cylinder 20 and the internal telescopic rod.

[0023] In the sixth embodiment, since the rear ends of the two forks 6 are slidably connected to the movable plate 3, there must be a certain distance between the lower surfaces of the two forks 6 and the ground. This results in that when the cable roll is forked, the forks 6 cannot be effectively grounded, which not only affects the forking of the cable roll, but also the forks 6 are suspended in the air and subjected to force when forked, which can easily cause damage to the connection of the forks 6. In order to enable the forks 6 to be effectively attached to the ground, a thickened layer 19 is provided at the lower part of the forks 6 located in front of the movable plate 3. The thickened layer 19 is an integrated structure with the forks 6, and its lower surface is flush with the lower edge of the movable plate 3.

[0024] The parts of the present invention that are not described in detail are prior art. It is obvious to those skilled in the art that the present invention is not limited to the details of the above-mentioned exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention.
