[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.
[0029] Please see Figure 1-8 This utility model provides a technical solution:
[0030] A protective structure for an electric pallet truck includes a truck body 1 and a lifting mechanism 2. The lifting mechanism 2 is fixedly connected to the right side of the truck body 1. An adjusting mechanism 3 is installed inside the lifting mechanism 2. A bracket assembly 4 is installed at one end of the adjusting mechanism 3. A blocking component 5 is fixedly connected to the lower end of the bracket assembly 4. The bracket assembly 4 includes a bracket 41. A guide hole 42 is opened inside the bracket 41. A double column rod 43 is slidably connected inside the guide hole 42 of the bracket 41. A linear spring 44 is fixedly connected to one end of the double column rod 43. A rigid plate 45 is fixedly connected to the right side of the double column rod 43. A rubber plate 46 is fixedly connected to the right side of the rigid plate 45. The bracket 41 has a spring groove 47 on its inner side, and a spring 48 is fixedly connected to the inner side of the spring groove 47 on the bracket 41. A baffle 49 is fixedly connected to the inner side of the lower end of the bracket 41. The blocking assembly 5 includes a buffer plate 51. A shaft column 52 is fixedly connected to the front and rear ends of the buffer plate 51. A vertical plate 53 is fixedly connected to the bottom end of the buffer plate 51. A pull rope 54 is fixedly connected to the outer side of the vertical plate 53. The outer side of the pull rope 54 is in contact with the outer side of the rotating wheel 55. A take-up wheel 56 is fixedly connected to one end of the pull rope 54. A fixed plate 57 is rotatably connected to the outer side of the take-up wheel 56. The front end of the fixed plate 57 is fixedly connected to the end of the spindle of the servo motor 58.
[0031] As a further implementation of this solution, the left end of the bracket 41 slides on the outside of the adjustment mechanism 3, the guide hole 42 penetrates the inside of the bracket 41, and two guide holes 42 are opened inside the bracket 41. There are two double-column rods 43, which are composed of two cylinders of different sizes. The right side of the linear spring 44 is fixedly connected to the left side of the bracket 41. A gap is provided between the rigid plate 45 and the bracket 41. When handling fragile goods, the cushioning of the linear spring 44 can prevent the goods from colliding with the bracket 41 and improve the safety of handling fragile goods.
[0032] As a further implementation of this solution, a groove is provided on the inner side of the bracket 41 near the buffer plate 51. The buffer plate 51 is embedded in the groove of the bracket 41 and fits against the top of the baffle 49. The pull rope 54 is located at the lower end of the baffle 49, which facilitates the movement of the buffer plate 51 and its storage inside the bracket 41 without affecting the handling of the tray. At the same time, the limiting effect of the baffle 49 can prevent the buffer plate 51 from protruding downwards from the outside of the bracket 41.
[0033] As a further implementation of this solution, the spring groove 47 is shaped like two cylindrical sections. The spring groove 47 penetrates the inner side of the bracket 41, and there are two spring grooves 47. The spring grooves 47 are connected to the grooves opened in the bracket 41. The shaft 52 is cylindrical in shape and is rotatably connected to the inner side of the spring groove 47. The outer side of the shaft 52 is fixedly connected to one end inside the spring groove 47. There are two shafts 52 and two spring springs 48. The shaft 52 rotates inside the spring groove 47 to limit the rotation of the buffer plate 51. The elastic torque of the spring spring 48 drives the buffer plate 51 to rotate, which limits the movement of the goods and also cushions the goods.
[0034] As a further implementation of this solution, a groove is provided on the inner side of the bracket 41 near the pull rope 54, and the pull rope 54 is located inside the groove of the bracket 41. The front and rear ends of the rotating wheel 55 are rotatably connected to the inner side of the bracket 41. A shaft hole is provided on the inner side of the fixing plate 57, and the right side of the fixing plate 57 is fixedly connected to the left side of the bracket 41. The servo motor 58 can be fixedly connected to the front end of the fixing plate 57. By starting the servo motor 58, the pull rope 54 can be released and coiled outside the take-up wheel 56, thereby controlling the rotation of the buffer plate 51.
[0035] Workflow: During the handling of fragile goods, to ensure the stability of the goods while reducing the risk of damage, the existing lifting mechanism 2 controls the lifting of the bracket assembly 4, and the existing adjusting mechanism 3 controls the position between the two bracket assemblies 4. After adjustment, the lower end of the bracket 41 is moved to the lower end of the pallet containing the fragile goods by the transport vehicle body 1. The movement of the transport vehicle body 1 moves the bracket 41. When the pallet passes the blocking assembly 5 and the pallet contacts the right side of the rubber plate 46, the movement of the bracket assembly 4 is stopped. The movement is initiated by the servo motor 58, which drives the take-up reel 56 to rotate. The take-up reel 56 is rotatably connected to the inner side of the fixed plate 57. When the take-up reel 56 rotates, the pull rope 54 is released. The outer side of the pull rope 54 is in contact with the outer side of the rotating wheel 55. When the pull rope 54 is released, it rotates due to friction. The rotating wheel 55 can cover the direction of movement of the pull rope 54 and prevent friction between the pull rope 54 and the bracket 41. When the pull rope 54 is released, under the torque of the spring 48, the spring 48 drives the shaft 52 and the buffer plate 51 to rotate. As the vehicle rotates, the buffer plate 51 rotates inside the groove of the bracket 41, gradually rotating towards the upper part of the bracket 41. The shaft 52 is rotatably connected inside the spring groove 47, which limits the rotation of the buffer plate 51. When one side of the buffer plate 51 slightly contacts the goods, the servo motor 58 stops, and the main shaft of the servo motor 58 is locked, preventing the pull rope 54 from moving. At this time, the goods are effectively limited. When the transport vehicle body 1 moves, the buffer plate 51 greatly reduces the risk of goods slipping. Meanwhile, when the transport vehicle body 1 is transporting goods, when the goods are squeezed against the rubber plate 46, the linear spring 44 plays a buffering role to prevent the goods from colliding with the bracket 41. When the goods are squeezed against the buffer plate 51, the elastic torque of the spring spring 48 plays a buffering role to reduce the damage to the goods caused by excessive reaction force when the goods are squeezed against the buffer plate 51. When the buffer plate 51 is reset, the servo motor 58 is started according to the above principle until one side of the buffer plate 51 contacts the upper end of the baffle 49.
[0036] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
