TECHNICAL FIELD

[0001] The utility model relates to the technical field of conveying device, especially a bidirectional push-pull supporting and limiting device. BACKGROUND

[0002] The automatic high-efficiency storage library is a kind of warehouse building specially used for storing and taking heavy products, and is usually equipped with roller device for moving and loading.The automatic high-efficiency storage library can significantly improve the storage efficiency, reduce manual intervention, reduce operating costs, and ensure higher accuracy and safety.

[0003] Compared with the traditional lifting and moving storage library, the heavy products on the roller device are moved and stored and taken away by moving and loading power equipment, which has obvious advantages in safety and efficiency.However, in the practical application process of the automatic high-efficiency storage library, not all heavy products can be directly placed between the rollers to complete the moving and loading operation.For example, some heavy products use container-type outer packaging, and have container-type corner seats at the bottom.This kind of heavy product cannot be directly contacted with the roller device.Therefore, the automatic high-efficiency storage library has certain limitations when storing and taking the heavy products with container-type outer packaging with corner seats.

[0004] From the above prior art, it can be seen that the heavy products with container-type outer packaging cannot be directly contacted with the moving and loading roller, and are difficult to be stored and taken by the automatic high-efficiency storage library. CONTENT OF THE UTILITY MODEL

[0005] Therefore, the utility model aims at providing a bidirectional push-pull supporting and limiting device, which supports and limits the heavy products with container-type outer packaging with corner seats, has sufficient structural strength and wear resistance, and can be transported on the moving and loading roller device.

[0006] To achieve the above-mentioned purpose, the technical scheme of the utility model is as follows:

[0007] A bidirectional push-pull supporting and limiting device, comprising a lining plate, which is slidably arranged on a moving and loading roller for goods transportation;

[0008] A supporting assembly is arranged on the lining plate;

[0009] A locking assembly is arranged on the supporting assembly, and a plurality of locking assemblies are distributed along the length direction of the supporting assembly;

[0010] A connecting rod is detachably connected between two adjacent locking assemblies to realize the synchronization of locking or unlocking action of multiple locking assemblies;

[0011] A limiting assembly is arranged on the supporting assembly to limit the locking assembly to remain in the locked or unlocked state.

[0012] Further, the locking assembly comprises a bottom cover.

[0013] A gear is rotatably arranged on the bottom cover.

[0014] A lock tongue is coaxially arranged with the gear.

[0015] A lock shell is buckled on the bottom cover to enclose the gear inside.

[0016] A cylindrical rack is slidably arranged on the lock shell and engaged with the gear.

[0017] A first limiting column is vertically arranged on the bottom cover to limit the rotation angle of the gear.

[0018] Further, the locking assembly further comprises a second limiting column.

[0019] The second limiting column is vertically arranged on the bottom cover to limit the rotation of the cylindrical rack.

[0020] Further, both ends of the cylindrical rack are provided with threaded segments, and both ends of the connecting rod are threadedly connected with two adjacent cylindrical racks.

[0021] Further, the lock shell is configured as two parts arranged symmetrically and clamped with each other.

[0022] Further, the limiting assembly comprises a buckle arranged on the cylindrical rack and clamped on the supporting assembly.

[0023] A threaded handle is arranged on the cylindrical rack and abuts against the buckle.

[0024] Further, the supporting assembly comprises a bearing beam vertically arranged on the backing plate.

[0025] An end plate is vertically connected between the two bearing beams.

[0026] Further, the backing plate is segmentally clamped on the lower surface of the bearing beam.

[0027] Compared with the prior art, the utility model has the following advantages:

[0028] The utility model discloses a bidirectional push-pull support limiting device, through set up the lining plate, can avoid being supported subassembly or the heavy product of being transported and the roll surface of the roll way direct contact, the lining plate has good rigidity and wear resistance ability, has improved the service life of the whole application. Through setting up the support subassembly on the lining plate, can play the main supporting role to the heavy product, and provides the installation position for the installation of locking assembly. The locking assembly can lock the heavy product transported and fixed, avoids the dislocation of the heavy product transported in the conveying process due to vibration and other reasons, is favorable to improving the stability of goods transportation. The connecting rod can ensure that the locking or unlocking action of multiple locking assemblies can be carried out synchronously, ensuring the convenience of the use process. The limiting component plays a limiting role on the locking assembly, can make the locking or unlocking state of the locking assembly not change due to vibration, knock and other unexpected situations in the transportation process, further improve the stability of goods transportation.

[0029] Secondly, by setting the locking assembly with the structure of the bottom cover, gear, lock tongue, lock shell, cylindrical rack and first limiting column, when the cylindrical rack and the lock shell slide relative to each other, the gear can be driven to rotate, and the lock tongue installed on the gear also rotates synchronously, and the lock tongue cooperates with the similar container corner seat arranged at the bottom of the heavy product container to realize clamping locking or unlocking. The lock shell buckled outside the gear plays a sealing and dustproof role on the transmission structure of the gear and the cylindrical rack, and also plays a limiting role on the axial direction of the gear. The first limiting column plays a limiting role on the rotation angle of the gear, so that the rotation angle of the gear can meet the required rotation angle range of the lock tongue and the similar container corner seat for clamping locking or unlocking, and the cylindrical rack and the gear will not be disengaged.

[0030] By setting the second limiting column on the bottom cover, the rotation of the cylindrical rack around its own axis can be limited, and the transmission jamming, gear grinding and gear breaking caused by the disengagement of the cylindrical rack and the gear can be avoided.

[0031] By setting the threaded segments at both ends of the cylindrical rack and setting the two ends of the connecting rod between the cylindrical racks of two adjacent locking assemblies in a threaded connection manner, on the one hand, multiple cylindrical racks can be connected through the connecting rod to realize synchronous linkage of the locking or unlocking action of multiple locking assemblies, and on the other hand, the length of the threaded matching part of the connecting rod and the cylindrical rack can be adjusted to adjust the spacing between the locking assemblies, so as to adapt to the transportation requirements of heavy products of different sizes.

[0032] By constructing the lock shell into two parts that are mirror-symmetrically distributed and interlocked, the processing difficulty and assembly difficulty of the internal structure features of the locking assembly can be reduced, and the economic applicability of the whole application can be improved.

[0033] In addition, by setting the limiting assembly as a buckle clamped on the support assembly and a threaded handle threaded on the cylindrical rack and abutting on the buckle, the limiting assembly can limit the relative position between the cylindrical rack and the support assembly after the cylindrical rack is fixedly connected with the support assembly, so that the heavy product cannot move during transportation, and the stability of the heavy product during transportation is ensured.

[0034] In addition, by setting the support assembly as a rectangular frame structure surrounded by the load-bearing beams and end plates, the load-bearing beams adopt the grid type welded structure I-beams as the load-bearing main body, which has the advantages of light weight and large rigidity. The end plates installed at both ends of the load-bearing beams support the installation of the limiting assembly. By adopting the segmented clamping and embedding structure of the lining plate, the heat treatment deformation amount of the lining plate is reduced, and the wear resistance of the lining plate is improved.

[0047] The embodiment relates to a bidirectional push-pull supporting and limiting device which supports and limits heavy products with container outer packaging having an angle base, has high structural strength and good wear resistance, and enables the supported heavy products to be transported on a transfer roller device.

[0048] Overall structure, referring to Figure 1 The bidirectional push-pull supporting and limiting device comprises a lining plate 1, a supporting assembly 2, a locking assembly 3, a connecting rod 4 and a limiting assembly 5. The lining plate 1 is attached to and slidably arranged on a transfer roller for goods transportation, the supporting assembly 2 is installed on the lining plate 1, the locking assembly 3 is installed on the supporting assembly 2, and the number of the locking assembly 3 can be adjusted according to the outer packaging structure of the heavy products to be actually transported. The connecting rod 4 is detachably connected between the multiple locking assemblies 3, so as to realize synchronous linkage of locking and unlocking actions of the multiple locking assemblies 3. The limiting assembly 5 is installed on the supporting assembly 2, so that the locking assembly 3 is kept in the locked or unlocked state.

[0049] As arranged above, the lining plate 1 can avoid direct contact between the supporting assembly 2 or the transported heavy products and the roller surface of the transfer roller, the lining plate 1 itself has good rigidity and wear resistance, and the service life of the whole device is improved. The supporting assembly 2 arranged on the lining plate 1 can mainly support the heavy products and provide an installation position for the locking assembly 3. The locking assembly 3 can lock and fix the transported heavy products, avoids dislocation of the heavy products due to vibration and other reasons during transportation, and is beneficial to improving the stability of goods transportation. The connecting rod 4 can ensure that the locking or unlocking actions of the multiple locking assemblies 3 are synchronous, and the convenience during use is ensured. The limiting assembly 5 limits the locking assembly 3, can prevent the locking or unlocking state of the locking assembly 3 from being changed due to vibration, collision and other unexpected conditions during transportation, and further improves the stability of goods transportation.

[0050] Referring to Figure 1 and Figure 2The locking assembly 3 comprises a bottom cover 301, a gear 302, a lock tongue 303, a lock shell 304, a cylindrical rack 305 and a first limiting column 306. The bottom cover 301 can be a circular metal sheet with a center hole. The wheel shaft of the gear 302 is inserted into the bottom cover 301, so that the gear 302 is arranged rotatably on the bottom cover 301. The lock tongue 303 is coaxially arranged with the gear 302 and can rotate synchronously with the gear 302. The lock shell 304 is buckled above the bottom cover 301, and the gear 302 is enclosed inside. The cylindrical rack 305 is arranged penetratingly and slidably on the lock shell 304, and the cylindrical rack 305 is engaged with the gear 302. The first limiting column 306 is a solid cylinder arranged perpendicularly to the bottom cover 301. A second limiting column 307 is also arranged perpendicularly on the bottom cover 301. The second limiting column 307 can be a solid cylinder abutting against one side of the cylindrical rack 305. The second limiting column 307 can limit the rotation of the cylindrical rack 305. Threaded segments are arranged at both ends of the cylindrical rack 305. The two ends of the connecting rod 4 are respectively threadedly connected with the two ends of the cylindrical rack 305 of two adjacent locking assemblies 3. The lock shell 304 is configured as two parts which are mirror-symmetrically distributed and are clamped with each other.

[0051] By arranging the bottom cover 301, the gear 302, the lock tongue 303, the lock shell 304, the cylindrical rack 305 and the first limiting column 306 of the locking assembly 3, when the cylindrical rack 305 slides relative to the lock shell 304, the gear 302 can be driven to rotate, and the lock tongue 303 mounted on the gear 302 is thus synchronously rotated, so as to realize clamping locking or unlocking with the container-like corner seat arranged at the bottom of the heavy product container outer package. The lock shell 304 buckled outside the gear 302 plays a sealing and dustproof role for the transmission structure of the gear 302 and the cylindrical rack 305, and plays a limiting role for the axial direction of the gear 302. The first limiting column 306 plays a limiting role for the rotation angle of the gear 302, so that the rotation angle of the gear 302 can meet the required rotation angle range for clamping locking or unlocking of the lock tongue 303 with the container-like corner seat, and the gear 302 will not be excessively rotated to cause disengagement between the cylindrical rack 305 and the gear 302.

[0052] By arranging the second limiting column 307 on the bottom cover 301, the rotation of the cylindrical rack 305 around its own axis direction can be limited, so as to avoid the occurrence of phenomena such as transmission jamming, gear grinding and gear breaking caused by disengagement between the cylindrical rack 305 and the gear 302.

[0053] By setting threaded sections at both ends of the cylindrical rack 305, and setting both ends of the connecting rod 4 between two adjacent locking assemblies 3 in a threaded connection manner, on the one hand, a plurality of cylindrical racks 305 can be connected by the connecting rod 4 to realize the synchronous linkage of the locking or unlocking actions of the plurality of locking assemblies 3, on the other hand, the length of the threaded fitting part of the connecting rod 4 and the cylindrical rack 305 can be adjusted to adjust the spacing between the locking assemblies 3 to adapt to the transportation needs of heavy products of different sizes.

[0054] By constructing the lock shell 304 as two parts that are mirror-symmetrically distributed and interlocked, the machining and assembly difficulties of the internal structure characteristics of the locking assembly 3 can be reduced, and the overall economic applicability of the present application can be improved.

[0055] Referring to Figure 1 , Figure 2 and Figure 3 , the limiting assembly 5 includes a buckle 501 and a threaded handle 502. The buckle 501 is sleeved on the cylindrical rack 305 and clamped on the support assembly 2. The threaded handle 502 is threadedly connected to the cylindrical rack 305 passing through the buckle 501 and abuts against the end face of the buckle.

[0056] By setting the limiting assembly 5 as the buckle 501 clamped on the support assembly 2 and the threaded handle 502 threadedly connected to the cylindrical rack 305 and abutting against the buckle 501, the limiting assembly 5 can limit the relative position between the cylindrical rack 305 and the support assembly 2 after completing the connection and fixation with the cylindrical rack 305, so that it cannot move, ensuring the stability of the heavy product during transportation.

[0057] Referring to Figure 1 , Figure 2 and Figure 4 , the support assembly 2 includes a load-bearing beam 201 and an end plate 202. The load-bearing beam 201 adopts a grid type welded structure I-beam as the main weight bearing body. The number of load-bearing beams 201 is two, and the two load-bearing beams 201 are arranged in parallel with each other. The end plate 202 is arranged at the head and tail positions between the two load-bearing beams 201, and together with the two load-bearing beams 201 forms a rectangular frame structure. The lining plate 1 is segmented and clamped and embedded in the lower surface between the two load-bearing beams 201.

[0058] By setting the support assembly 2 as a rectangular frame structure surrounded by the load-bearing beam 201 and the end plate 202, wherein the load-bearing beam 201 adopts a grid type welded structure I-beam as a weighing main body, which has the advantages of light weight and large rigidity. The end plate 202 installed at both ends of the load-bearing beam 201 plays a supporting role for the installation of the limiting assembly 5. By adopting the segmented clamping embedded structure of the lining plate 1, the heat treatment deformation amount of the lining plate 1 is reduced, and the wear resistance of the lining plate 1 is improved.

[0059] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not limited. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application, which should be covered in the scope of the claims of the present application.
