Description

Technical Field

[0001] The utility model belongs to the technical field of shelves, and particularly relates to a unilateral telescopic cantilever shelf. Background Technique

[0002] Most of the existing telescopic cantilever shelves are used to store bilateral telescopic pipe materials. For example, a Chinese patent with the authorization announcement number of CN220431185 discloses an electric telescopic cantilever shelf, which can control the driving transmission component through the electric control box component to drive the storage shelf component to achieve automatic telescoping, greatly increasing the loading and unloading efficiency of the telescopic cantilever shelf and realizing the intelligence of the telescopic cantilever shelf;

[0003] However, when in use, due to space limitations, it is often encountered that only unilateral telescopic picking is allowed. If a bilateral telescopic cantilever is still used, the equipment is heavy and the cost will be wasted. For this reason, we propose a unilateral telescopic cantilever shelf. Content of the Utility Model

[0004] The purpose of the utility model is to provide a unilateral telescopic cantilever shelf, which can reduce the occupied space of the shelf, and the structure of the shelf is relatively simple, which can reduce the cost, reduce the weight of the shelf and facilitate transportation.

[0005] The technical solution adopted by the utility model is specifically as follows:

[0006] A unilateral telescopic cantilever shelf includes side brackets and a plurality of main beams arranged in parallel. The plurality of main beams are connected by first tie rods. A base welding rib plate is fixedly connected to the lower end of the main beam. A plurality of sleeves are fixedly connected to the main beam and arranged in sequence from top to bottom. The sleeves are horizontally arranged. A telescopic arm is horizontally slidably connected to the sleeve. The telescopic arm can slide out through the front end of the sleeve. A ratchet gear is rotatably connected to the front end of the sleeve. A ratchet rack meshed with the ratchet gear is fixedly connected to the telescopic arm. A plurality of hand cranks are rotatably connected to the side brackets and arranged in sequence from top to bottom. A connecting pipe is fixedly connected to the hand crank. The connecting pipe is fixedly connected to the ratchet gear.

[0007] Further, the telescopic arm includes side guide wheels slidably connected inside the sleeve. The front end of the side guide wheel is located at the front end of the sleeve and fixedly connected to a vertically arranged front column. A telescopic arm welding part horizontally arranged above the side guide wheel is fixedly connected to the front column. The telescopic arm welding part is located above the sleeve. A vertically arranged rear column is fixedly connected to the rear end above the telescopic arm welding part. The ratchet rack is fixedly connected to the lower side of the side guide wheel. The ratchet gear is located below the ratchet rack.

[0008] Further, the rear end of the telescopic arm welding part is rotatably connected to an upper walking bearing located at the upper end of the sleeve.

[0009] Furthermore, a bottom traveling bearing is rotatably connected to the rear end of the side guide wheel located inside the casing.

[0010] Furthermore, a vertically arranged strengthening column is fixedly connected to the rear ends of a plurality of casings on the main beam. A connecting frame is fixedly connected to the upper ends of the main beam and the strengthening column. A top cross beam is fixedly connected to the connecting frame. A front column and a rear column are respectively fixedly connected to the front end and the rear end on the upper side of the top cross beam.

[0011] Furthermore, the side support includes a hand-crank column and an auxiliary column arranged in parallel. A plurality of hand-crank drives are rotatably connected to the auxiliary column. A second pull rod is fixedly connected between the hand-crank column and the auxiliary column.

[0012] Furthermore, a protective column piece is placed on one side of the plurality of main beam assemblies away from the side support.

[0013] The technical effects achieved by the present utility model are as follows:

[0014] With the one-sided telescopic cantilever shelf of the present utility model, only a space needs to be reserved at the front end of the shelf by means of one-sided telescopic picking, which can reduce the occupied space of the shelf. Moreover, the structure of the shelf is relatively simple, which can reduce costs, reduce the weight of the shelf, and facilitate transportation. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to make the purpose and advantages of the present utility model clearer and more understandable, the present utility model will be specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific implementation manners of the present utility model, and does not strictly limit the scope of protection specifically claimed for the present utility model.

[0023] As Figures 1-5 shown, a unilateral telescopic cantilever shelf includes side brackets arranged in parallel and a plurality of main beams 1. The plurality of main beams 1 are connected by a first tie rod 3, so that the plurality of main beams 1 form a frame structure and can be stably fixed. A base welding rib plate 18 is fixedly connected to the lower end of the main beam 1 to improve the stability when the main beam 1 is fixed.

[0024] As Figure 1 shown, in order to reduce the occupied space of the shelf, a plurality of sleeves 2 arranged in sequence from top to bottom are fixedly connected to the main beam 1. The sleeves 2 are arranged horizontally, and a telescopic arm is horizontally slidably connected to the sleeves 2. The telescopic arm can slide out through the front end of the sleeve 2. At this time, by the way of taking goods unilaterally and telescopically, only a space needs to be reserved at the front end of the shelf, reducing the occupied space of the shelf.

[0025] As Figure 1 shown, in order to drive the telescopic arm to move, a gear 10 is rotatably connected to the front end of the sleeve 2, and a rack 9 meshing with the gear 10 is fixedly connected to the telescopic arm. At this time, by rotating the gear 10, the rack 9 can be pushed to move the telescopic arm. A plurality of hand cranks 13 arranged in sequence from top to bottom are rotatably connected to the side brackets. A connecting pipe 14 is fixedly connected to the hand crank 13, and the connecting pipe 14 is fixedly connected to the gear 10. When the user rotates the hand crank 13, kinetic energy can be input to the gear 10 through the connecting pipe 14 to drive the gear 10 to rotate. At this time, the structure of the shelf is relatively simple, which can reduce costs, reduce the weight of the shelf, and facilitate transportation.

[0026] Here, the hand crank 13 is a workpiece rotatably connected to the side bracket. The user can directly twist it by hand or rotate it with a tool. The hand crank 13 can also be a motor, and the motor can directly drive the connecting pipe 14 to rotate.

[0027] As Figures 1-3As shown in the figure, the telescopic arm includes side guide wheels 4 slidably connected inside the sleeve 2. The front end of the side guide wheel 4 is located at the front end of the sleeve 2 and is fixedly connected to a vertically arranged front column 6. A telescopic arm welding part 5 arranged horizontally is fixedly connected to the front column 6 and is located above the side guide wheel 4. The telescopic arm welding part 5 is located above the sleeve 2. The rear end on the upper side of the telescopic arm welding part 5 is fixedly connected to a vertically arranged rear column 7. At this time, the pipe materials can be placed on multiple telescopic arm welding parts 5 and at the position between the front column 6 and the rear column 7. By arranging the front column 6 and the rear column 7, the phenomenon of the pipe materials falling can be reduced. The ratchet rack 9 is fixedly connected to the lower side of the side guide wheel 4, and the ratchet gear 10 is located below the ratchet rack 9.

[0028] As Figures 1-3 shown, the rear end of the telescopic arm welding part 5 is rotatably connected to an upper walking bearing 8 located at the upper end of the sleeve 2. Through the arrangement of the upper walking bearing 8, it can be used as the support for the rear end of the telescopic arm welding part 5, thereby improving the stability of the telescopic arm.

[0029] Similarly, the rear end of the side guide wheel 4 located inside the sleeve 2 is rotatably connected to a bottom walking bearing 21 to reduce the wear during the movement of the side guide wheel 4.

[0030] As Figure 1 and Figure 4 shown, a vertically arranged strengthening column 16 is fixedly connected to the rear ends of multiple sleeves 2 on the main beam 1. By arranging the strengthening column 16, multiple sleeves 2 can be strengthened. A connecting frame 19 is fixedly connected to the upper ends of the main beam 1 and the strengthening column 16. A top cross beam 20 is fixedly connected to the connecting frame 19. The front column 6 and the rear column 7 are respectively fixedly connected to the front end and the rear end on the upper side of the top cross beam 20, thereby being able to increase the storage space of the shelf.

[0031] As Figure 1 and Figure 5 shown, the side bracket includes a hand-cranked column 11 and an auxiliary column 12 arranged in parallel. Multiple hand-cranked drives 13 are rotatably connected to the auxiliary column 12. A second pull rod 15 is fixedly connected between the hand-cranked column 11 and the auxiliary column 12. At this time, the side bracket structure composed of the hand-cranked column 11, the auxiliary column 12 and the second pull rod 15 is relatively simple, has a low weight, and is convenient for transportation.

[0032] At the same time, a protective column piece 17 is placed on one side of the combination of multiple main beams 1 away from the side bracket. By arranging the protective column piece 17, the placement area can be restricted, and the collision between personnel and the main beam 1 can be reduced.

[0033] The working principle of the present utility model is as follows:

[0034] When using the shelf, the rotatable hand crank drive 13 can be rotated to drive the connecting pipe 14 to rotate. Kinetic energy is input into the gear 10 through the connecting pipe 14, driving the gear 10 to rotate. By rotating the gear 10, the rack 9 can be pushed, enabling the telescopic arm to move back and forth. When the telescopic arm extends, the pipe materials can be placed on multiple telescopic arms. When the telescopic arm retracts, the storage of the pipe materials can be completed.

[0035] In summary, through the method of unilateral telescopic picking, this technical solution only needs to reserve space at the front end of the shelf, which can reduce the occupied space of the shelf. Moreover, the structure of the shelf is relatively simple, which can reduce costs, reduce the weight of the shelf, and facilitate transportation.

[0036] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention. The structures, devices, and operation methods not specifically described and explained in the present invention are implemented according to the conventional means in the art without special explanation and limitation.
