Description

Technical Field

[0001] The utility model relates to a cantilever shelf capable of rotating at multiple angles, belonging to the technical field of cantilever shelves. Background Art

[0002] Cantilever racks are mainly composed of uprights, cantilever beams, connecting rods, etc. They are characterized by a lightweight forward cantilever structure and strong load-bearing capacity. They can greatly improve warehouse utilization and work efficiency for storing irregular or long rod materials. The cantilever can be single-sided or double-sided. After adding wooden boards or steel gratings, it is particularly suitable for warehouses with small space and low density. It is easy to manage and has a wide field of view. It is widely used in mechanical processing and building materials supermarket industries.

[0003] A Chinese patent publication (publication number: CN 209528643 U) discloses a cantilever shelf, comprising a supporting bottom beam, a vertical supporting beam, and a horizontal connecting plate. The vertical supporting beam is disposed on the supporting bottom beam, cantilever beams are disposed on both sides of the vertical supporting beam, a fixed mounting seat is disposed behind the cantilever beam, a hanging tag is disposed on the cantilever beam, a writing card is disposed inside the hanging tag, a support seat is disposed on the top of the hanging tag, a hanging hook is disposed inside the support seat, the horizontal connecting plate is disposed between the vertical supporting beams, diagonal tie bars are disposed between the horizontal connecting plates, and a serial number plate is disposed on one side of the vertical supporting beam.

[0004] However, since cantilever racks are generally used in warehouses with smaller spaces, when the rear cantilever of the cantilever rack is close to the wall, the forklift may not be able to place materials on the cantilever near the wall. At the same time, the inner spacing of the cantilever rack is usually not adjustable, so the length of the materials that can be placed on the cantilever rack is limited, making it impossible to place shorter materials on the cantilever rack, resulting in a limit on the materials that can be placed on the cantilever rack.

[0005] Therefore, a cantilever shelf capable of rotating at multiple angles is proposed. Utility Model Content

[0011] Further preferably, a servo motor is fixedly installed on the left side of the box body, and a bidirectional screw is fixedly connected to the output end of the servo motor. Screw blocks are threadedly connected on the left and right sides of the surface of the bidirectional screw, and the bottoms of the two T-shaped blocks are fixedly installed on the tops of the two screw blocks.

[0012] Further preferably, an annular groove is provided on the top of the box body, sliding blocks are fixedly installed around the bottom of the turntable, and the bottoms of the six sliding blocks are slidably connected to the inner cavity of the annular groove.

[0013] Further preferably, sliding grooves are provided on both the front and rear sides of the top of the box body, and the bottoms of the four movable wheels are slidably connected to the inner cavities of the two sliding grooves.

[0017] The embodiment of the present invention has the following advantages due to the adoption of the above technical solution:

[0018] First, the utility model sets a rotation adjustment mechanism, which makes the polished rod rotate through the output of the bidirectional motor. At this time, the two polished rods rotate in opposite directions and synchronously drive the two active bevel gears to rotate in opposite directions. Due to the rotation of the active bevel gear, the driven bevel gear drives the turntable to rotate, thereby driving the spacing adjustment mechanism on the top of the turntable and the support rod and cantilever rod to rotate, so that the cantilever rod close to the wall can be moved away from the wall, making it convenient for a forklift to collect materials placed on the top of the cantilever rod, improving the convenience of using the cantilever rod and the support rod in a narrow space, and effectively avoiding the cantilever rod from being pulled out of the cantilever. There is a section of the rod close to the wall, which makes it impossible for the forklift to place or unload the material on the top of the cantilever rod. By setting up a spacing adjustment mechanism, the servo motor can drive the bidirectional screw to rotate. As the bidirectional screw rotates, the screw block moves inward along the thread on the surface of the bidirectional screw. As the screw block moves, the T-shaped block drives the support rod and the cantilever rod to move inward synchronously, thereby facilitating the adjustment of the spacing between the inner sides of the two support rods and facilitating the placement of materials of different lengths, thereby avoiding the situation where the material is too short to be placed on the top of the cantilever rod, thereby affecting the placement of the material.

[0019] The present invention can limit the movement of the T-shaped block and avoid the deviation of the direction of movement of the screw block when the T-shaped block moves, thereby affecting the adjustment work of the distance between the support rod and the cantilever rod, and can facilitate the disassembly or installation of the overall spacing adjustment mechanism by arranging the fixing block and the fixing bolt, so as to facilitate the disassembly, inspection or maintenance of the components in the spacing adjustment mechanism.

[0029] Hereinafter, only certain exemplary embodiments are briefly described. As will be appreciated by those skilled in the art, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and description are to be regarded as illustrative in nature and not restrictive.

[0030] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0031] Example 1

[0032] like Figure 1-6 As shown, the embodiment of the present invention provides a cantilever shelf that can rotate at multiple angles, including a box body 1, wherein support rods 4 are provided on both the left and right sides of the top of the box body 1, and cantilever rods 5 are provided on both the front and rear sides of the support rods 4. Screw grooves 6 are provided on the surfaces of the two support rods 4, and the outer sides of the twelve cantilever rods 5 are threadedly connected with mounting bolts 7, which are threadedly connected to the inner cavities of the screw grooves 6.

[0033] A rotation adjustment mechanism 2 is provided in the inner cavity of the housing 1. The rotation adjustment mechanism 2 includes a bracket 201, an active bevel gear 204 and a driven bevel gear 205. The two active bevel gears 204 are movably connected to the left and right sides of the inner cavity of the housing 1, and the driven bevel gear 205 is movably connected to the top of the inner cavity of the housing 1. The surfaces of the two active bevel gears 204 are meshed with the surfaces of the driven bevel gear 205. The top of the driven bevel gear 205 is fixedly connected to a turntable 206. The bracket 201 is fixedly installed. At the bottom of the inner cavity of the box body 1, a bidirectional motor 202 is fixedly installed on the top of the bracket 201. The output ends on both sides of the bidirectional motor 202 are fixedly connected to the polished rods 203. The two polished rods 203 rotate in opposite directions. The outer sides of the two polished rods 203 are fixedly connected to the inner side of the active bevel gear 204. An annular groove 207 is opened on the top of the box body 1, and sliding blocks 208 are fixedly installed around the bottom of the turntable 206. The bottoms of the six sliding blocks 208 are all slidably connected to the inner cavity of the annular groove 207.

[0034] By setting the rotation adjustment mechanism 2, the output of the bidirectional motor 202 causes the optical rod 203 to rotate. At this time, the two optical rods 203 rotate in opposite directions and synchronously drive the two active bevel gears 204 to rotate in the opposite directions. Due to the rotation of the active bevel gear 204, the driven bevel gear 205 drives the turntable 206 to rotate, thereby driving the spacing adjustment mechanism 3 and the support rod 4 and the cantilever rod 5 at the top of the turntable 206 to rotate, thereby facilitating the cantilever rod 5 near the wall end to move away from the wall, making it convenient for a forklift to collect materials placed on the top of the cantilever rod 5, improving the convenience of using the cantilever rod 5 and the support rod 4 in a narrow space, and effectively avoiding the situation where the cantilever rod 5 has a section close to the wall, which causes the forklift to be unable to place or unload materials on the top of the cantilever rod 5. By setting the annular groove 207 and the sliding block 208, the rotation of the turntable 206 can be limited to avoid the direction of deviation when the turntable 206 rotates, thereby affecting the adjustment work of the rotation of the cantilever rod 5 and the support rod 4.

[0035] Example 2

[0036] In one embodiment, a spacing adjustment mechanism 3 is provided on the top of the turntable 206. The spacing adjustment mechanism 3 includes a box body 301 and a T-shaped block 305. The box body 301 is fixedly mounted on the top of the turntable 206. The two T-shaped blocks 305 are arranged on the left and right sides of the inner cavity of the box body 301. The outer sides of the two T-shaped blocks 305 are movably connected with movable wheels 306. The bottoms of the two support rods 4 are fixedly mounted on the tops of the two T-shaped blocks 305. A servo motor 302 is fixedly mounted on the left side of the box body 301. The output end of the servo motor 302 is fixedly connected to a bidirectional screw 303. The left and right sides of the surface of the bidirectional screw 303 are threadedly connected with screw blocks 304. The bottoms of the two T-shaped blocks 305 are fixedly mounted on the two screw blocks 3 04, the top of the box body 301 is provided with a slide groove 307 on the front and back sides of the top, the bottom of the four movable wheels 306 are slidably connected to the inner cavity of the two slide grooves 307, the top of the box body 301 is provided with a moving groove 308, the two T-shaped blocks 305 pass through the inner cavity of the two moving grooves 308 and extend to the top of the box body 301, and a limiting groove 309 is provided at the bottom of the inner cavity of the box body 301. The bottoms of the two screw blocks 304 are slidably connected to the inner cavity of the limiting groove 309, and the left and right sides of the front and back sides of the box body 301 are fixedly installed with fixed blocks 310. The tops of the four fixed blocks 310 are threadedly connected with fixing bolts 311, and the bottoms of the four fixing bolts 311 are threadedly connected to the inner surface of the turntable 206.

[0037] By setting up the spacing adjustment mechanism 3, the servo motor 302 can drive the bidirectional screw 303 to rotate. As the bidirectional screw 303 rotates, the screw block 304 moves inward along the thread on the surface of the bidirectional screw 303. As the screw block 304 moves, the T-shaped block 305 drives the support rod 4 and the cantilever rod 5 to move inward synchronously, thereby facilitating the adjustment of the spacing between the inner sides of the two support rods 4 and facilitating the placement of materials of different lengths, thereby avoiding the situation where the material cannot be placed on the top of the cantilever rod 5 due to its short length, thereby affecting the placement of the material. By setting up the slide 307 and the movable wheel 306, the movable wheel 306 can maintain the positive direction when moving without offset, and can also support the support rod 4 and the cantilever rod 5, reducing The pressure on the surface of the screw block 304 and the bidirectional screw 303 can avoid the surface pressure of the screw block 304 being excessive, thereby affecting the adjustment of the distance between the support rod 4 and the cantilever rod 5. By setting the movable groove 308, the movement of the T-shaped block 305 can be limited to avoid the T-shaped block 305 from deviating when moving, thereby affecting the adjustment of the distance between the support rod 4 and the cantilever rod 5. By setting the limiting groove 309, the movement of the screw block 304 can be limited to avoid the direction of movement of the screw block 304 from deviating, thereby affecting the adjustment of the distance between the support rod 4 and the cantilever rod 5. By setting the fixing block 310 and the fixing bolt 311, the overall disassembly or installation of the spacing adjustment mechanism 3 can be facilitated, and the components in the spacing adjustment mechanism 3 can be disassembled, inspected or repaired.

[0038] When the present invention is working: the output of the bidirectional motor 202 causes the polished rod 203 to rotate. At this time, the two polished rods 203 rotate in opposite directions and synchronously drive the two active bevel gears 204 to rotate in opposite directions. Due to the rotation of the active bevel gear 204, the driven bevel gear 205 drives the turntable 206 to rotate, thereby driving the spacing adjustment mechanism 3 and the support rod 4 and the cantilever rod 5 on the top of the turntable 206 to rotate, completing the adjustment of the rotation of the support rod 4 and the cantilever rod 5, the servo motor 302 drives the bidirectional screw 303 to rotate, and as the bidirectional screw 303 rotates, the screw block 304 moves inward along the thread on the surface of the bidirectional screw 303, and as the screw block 304 moves, the T-shaped block 305 drives the support rod 4 and the cantilever rod 5 to move inward synchronously, completing the adjustment of the spacing between the inner sides of the two support rods 4.
