This solves the problem of existing library book transport carts requiring climbing ladders or bending over to retrieve books from higher and lower shelves, resulting in high labor intensity and inconvenience.

Description

Technical Field

[0001] This invention relates to the field of library equipment technology, and in particular to a library book transport cart. Background Technology

[0002] Libraries are public places that facilitate people's learning and access to information. They have a large number of borrowed books. After borrowed books are returned, staff need to put them back on their original shelves. There are many categories of books, and the workload of returning books by category is large. Usually, staff will use trolleys to complete this task to reduce labor.

[0003] When retrieving and returning books from the upper shelves of existing library book carts, librarians need to frequently climb ladders or step stools to manually pass them, which is labor-intensive. When retrieving and returning books from the lower shelves, the operation requires long periods of bending over, which is also labor-intensive and can easily lead to occupational diseases such as lumbar muscle strain, making it inconvenient to use. Summary of the Invention

[0004] The purpose of this invention is to provide a library book transport vehicle that solves the problem that existing library book transport vehicles require climbing ladders or bending over to retrieve books from high and low bookshelves, resulting in high labor intensity and inconvenience.

[0005] To achieve the above objectives, the present invention provides a library book transport cart, comprising a mobile frame, a ladder, and a lifting bookshelf. The ladder is fixedly connected to the mobile frame and located in the middle of the mobile frame. The lifting bookshelf is mounted on the mobile frame and located on both sides of the ladder. The lifting bookshelf includes a bookshelf body, a guardrail, a lifting frame, and a buffer frame.

Detailed Implementation

[0019] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0020] Please see Figures 1 to 4 This invention provides a library book transport cart, comprising a mobile frame, a ladder 1, and a lifting bookshelf. The ladder 1 is fixedly connected to the mobile frame and located in the middle of the mobile frame. The lifting bookshelf is mounted on the mobile frame and located on both sides of the ladder 1. The lifting bookshelf includes a bookshelf body 2, a guardrail 3, a lifting frame, and a buffer frame. The lifting frame is fixedly connected to the mobile frame and located at the top of the mobile frame. The bookshelf body 2 is fixedly connected to the lifting frame and located on the side of the lifting frame away from the mobile frame. The guardrail 3 is fixedly connected to the bookshelf body 2 and located on one side of the bookshelf body 2. The buffer frame is disposed between the bookshelf body 2 and the mobile frame.

[0021] In this implementation, the lifting bookshelf is used to hold returned books in the library. The mobile cart is pushed by the administrator to move the returned books within the library, placing them on the shelf to be placed. The administrator can then retrieve the returned books from the lifting bookshelf and place them on the shelf, completing the return operation. The top and sides of the bookshelf body 2 have control buttons. The buffer frame cushions the lifting of the bookshelf body 2, preventing books from shaking and falling due to rapid lifting. The protective railing 3 further enhances the protection of the books, preventing books from falling from the bookshelf body 2 when the administrator pushes the mobile cart around the library. If the administrator needs to move books to higher shelves... When returning books, the administrator can climb ladder 1 and then use the control button on the top of the bookshelf body 2 to control the lifting frame to lift the bookshelf body 2 and the books inside. At this time, the administrator can take out the books from the bookshelf body 2 for return without having to climb the stairs frequently. Similarly, when returning books at the bottom of the bookshelf body 2, the administrator only needs to use the control button on the side of the bookshelf body 2 to control the lifting frame to lift the bookshelf body 2, and the administrator can directly take the books from the ground without having to bend over frequently. This solves the problem of existing libraries using book transport carts to retrieve books from high and low shelves, which requires climbing ladders or bending over, resulting in high labor intensity and inconvenience.

[0022] Furthermore, the library book transport cart also includes a reinforcing rib 4 and a counterweight 5. The reinforcing rib 4 is fixedly connected to the bookshelf body 2 and is located on one side of the bookshelf body 2. The counterweight 5 is fixedly connected to the mobile frame and is located at the bottom of the ladder 1.

[0023] In this embodiment, the reinforcing rib 4 is used to enhance the structural strength of the bookshelf body 2, preventing the shelves of the bookshelf body 2 from deforming or cracking when carrying a large number of books or during lifting, thereby improving the overall structural stability and load-bearing capacity; the counterweight 5 is used to lower the overall center of gravity of the frame body, and is installed below the ladder 1 together with the external power supply of the lifting frame, to prevent the bookshelf from tipping over when it rises, when the administrator climbs the ladder 1, or when retrieving books from one side, thereby improving safety and stability during use.

[0024] Furthermore, the lifting frame includes a lifting cylinder 6, a top plate 7, and a telescopic guide rod 8. The top plate 7 is fixedly connected to the bookshelf body 2 and is located at the bottom of the bookshelf body 2. The lifting cylinder 6 is fixedly connected to the mobile frame, and its output end is fixedly connected to the top plate 7 and is located between the top plate 7 and the mobile frame. The telescopic guide rod 8 is fixedly connected to the top plate 7 and to the mobile frame, and is located around the lifting cylinder 6.

[0025] In this embodiment, the lifting cylinder 6 provides lifting power, and drives the top plate 7 to move up and down through telescopic movement, thereby driving the bookshelf body 2 to achieve lifting action; the top plate 7 is used to evenly support the weight of the bookshelf body 2, ensuring stable force during lifting; the telescopic guide rod 8 guides and limits the lifting path of the top plate 7 and the bookshelf body 2, avoiding deviation, shaking or jamming during lifting, so that the bookshelf body 2 can lift and lower stably in the vertical direction, improving lifting accuracy and operational reliability.

[0026] Furthermore, the buffer frame includes a connecting plate 9, a rotating rod 10, a sliding pressure block 11, and a buffer column. The connecting plate 9 is fixedly connected to the bookshelf body 2 and is located at the bottom of the bookshelf body 2. The sliding pressure block 11 is slidably connected to the mobile frame and is located at the top of the mobile frame. The rotating rod 10 is rotatably connected to the connecting plate 9 and rotatably connected to the sliding pressure block 11, and is located between the connecting plate 9 and the sliding pressure block 11. The buffer column is fixedly connected to the sliding pressure block 11 and is located between the sliding pressure blocks 11.

[0027] In this embodiment, the connecting plate 9 rises and falls synchronously with the bookshelf body 2, and the lifting motion is transmitted to the sliding pressure block 11 through the rotating rod 10, so that the sliding pressure block 11 slides relative to the top of the mobile frame; the buffer column dampens and buffers the sliding of the sliding pressure block 11, absorbs the impact and vibration generated during the lifting process, and avoids the bookshelf body 2 from lifting too fast or the books from shaking or tipping over when starting and stopping, thereby further improving the stability of the book transport and lifting process.

[0028] Furthermore, the buffer column includes a damping rod 12 and a buffer spring 13. The damping rod 12 is fixedly connected to the sliding pressure block 11 and is located between the sliding pressure blocks 11. The buffer spring 13 is sleeved on the outside of the damping rod 12.

[0029] In this embodiment, the buffer spring 13 absorbs the impact force generated by the relative movement of the sliding block 11 through elastic deformation, providing elastic buffering; the damping rod 12 is used to suppress the reciprocating rebound of the buffer spring 13, avoid oscillation, and make the buffering process smoother and more stable. The two work together to buffer the bookshelf body 2, effectively reducing the impact of vibration on the books during lifting and moving.

[0030] Furthermore, the mobile frame includes a tray 14 and a steering pulley. The tray 14 is fixedly connected to the ladder 1 and is located at the bottom of the ladder 1. The steering pulley is rotatably disposed at the bottom of the tray 14.

[0031] In this embodiment, the pallet 14 provides an installation base for the overall structure and is used to support the weight of the ladder 1, the lifting bookshelf, and the books; the steering pulley is used to support the whole vehicle and realize flexible steering, which makes it convenient for the administrator to push the book transport vehicle to move and turn in the library bookshelf aisle, thereby improving the convenience and flexibility of the transfer process.

[0032] Furthermore, the steering pulley includes a rotating shaft seat 15, a pulley 16, and a brake pad 17. The rotating shaft seat 15 is rotatably connected to the disc 14 and is located at the bottom of the disc 14. The pulley 16 is rotatably disposed on the side of the rotating shaft seat 15 away from the disc 14, and the brake pad 17 is rotatably disposed on the side of the rotating shaft seat 15 close to the pulley 16.

[0033] In this embodiment, the rotating shaft seat 15 enables the pulley 16 to rotate at multiple angles relative to the cart 14, ensuring smooth pushing; the pulley 16 is used to roll directly in contact with the ground, reducing movement resistance; the brake pad 17 is used to brake and lock the pulley 16, fixing the book cart when the administrator retrieves books, climbs the ladder 1, or stops, preventing accidental slippage and improving safety.

[0034] The above-disclosed embodiments are merely preferred embodiments of a library book transport vehicle provided by this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments, and equivalent variations made in accordance with the claims of this application, still fall within the scope of this application.
