Description

Technical Field

[0001] The present application relates to the field of conveyor chains, and in particular to a heavy-load mesh chain. Background Art

[0002] Currently, conveyor chains are suitable for transporting various types of boxes, bags, pallets, and other goods. Bulk materials, small items, or irregular items need to be placed on pallets or in turnover boxes for transportation. They can transport materials with very heavy individual pieces or withstand large impact loads.

[0003] In the prior art, a mesh chain comprises an endless chain consisting of multiple mesh chain units. Each mesh chain unit is composed of multiple chain plates. Pins are inserted between adjacent chain plates. The pins are simultaneously inserted between two adjacent chain plates, enabling a rotational connection between the two chain plates. The chain plates have grooves on their inner sides that engage with transmission gears, which drive the endless chain back and forth. Friction bumps are provided on the chain plates to increase the roughness of the chain plate surface, thereby reducing the risk of cargo slipping on the chain plates, which could affect their transport.

[0004] With respect to the above-mentioned prior art, during the transportation process, the goods are prone to slipping on the chain plates due to their own inertia or the need to tilt the mesh chain. The use of only friction bumps is not enough to cope with goods of various shapes, resulting in the phenomenon of goods still slipping. For this reason, in the prior art, a plurality of blocking blocks are arranged at intervals on the circular chain. The blocking blocks can support the goods and reduce the slipping of the goods. However, the interval-arranged blocking blocks fix the distance between two adjacent blocking blocks. When the distance is large, it is only suitable for large goods. If a large number of small goods are put in, there will still be the phenomenon of slipping and sliding out. Therefore, only a small number of small goods can be put in, affecting the transportation efficiency of the goods. When the distance is small, larger goods cannot be put in, affecting the convenience of goods transportation, and it is urgently needed to be improved. Summary of the Invention

[0005] In order to reduce the slipping phenomenon during cargo transportation, improve the stability of cargo transportation, and enable cargo to be transported more conveniently, the present application provides a heavy-load mesh chain.

[0006] The heavy-duty network chain provided in this application adopts the following technical solution:

[0007] The chain is hingedly connected to the chain plate by a plurality of hinged plates, and a plurality of rotating grooves are provided on the chain plate. A limit baffle is rotatably connected in the rotating groove. When the limit baffle is in the rotating groove, the side of the limit baffle away from the chain plate is in the same plane as the chain plate surface. The limit baffle is rotated out to support the goods. A first connecting wheel is provided on the side wall of the limit baffle. A plurality of second connecting wheels are rotatably connected on the adjacent chain plates in the transmission direction of the ring chain. A connecting belt is provided between the first connecting wheel and the second connecting wheel. The upper surface of the connecting belt is in the same plane as the chain plate surface. A pulling member for driving the limit baffle to reset is provided in the rotating groove.

[0008] By adopting the above technical solution, when working, the ring chain is transported normally, and the staff puts the goods on the chain plate. Under the action of inertia or gravity, the goods slide on the chain plate, and the goods will drive the connecting belt to rotate, thereby driving the limit baffle to rotate out of the rotating groove, thereby achieving the purpose of restricting the movement of goods, reducing the slipping of goods or reducing the distance of slipping of goods. With such a design, on the one hand, it can break through the requirements of fixed-interval blocking blocks for goods and improve the convenience of cargo transportation. On the other hand, it can meet the supporting role of goods, reduce the movement of goods due to inertia or gravity to overcome their own friction, and improve the stability of cargo transportation.

[0009] Preferably, a plurality of transmission grooves are provided on one side of the chain plate close to the transmission gear, and the transmission grooves cooperate with the transmission gear to drive the annular chain transmission. The transmission grooves are connected to the rotating groove, and the transmission gear is used to push the limit baffle out.

[0010] By adopting the above technical solution, during operation, when the chain plate is transmitted to the transmission gear, it means that the goods have reached the end of the ring chain pair. At this time, the goods can be supported by the transmission gear and the limit baffle, so that there is a gap between the goods and the ring chain, allowing staff to pick up the goods more conveniently, thereby improving the convenience of cargo handling.

[0011] Preferably, a support groove is provided on a side of the limit baffle close to the transmission gear, and the support groove is plug-fitted with the transmission gear.

[0012] By adopting the above technical solution and opening a support groove, the cargo pressure on the limit baffle can be better applied to the transmission gear, reducing the pressure on the rotating connection of the limit baffle, reducing the pressure on the limit baffle, and improving the service life of the limit baffle.

[0013] Preferably, a limiting arc groove is provided on the side wall of the rotating groove, and a limiting block is provided on the side wall of the limiting baffle plate for sliding cooperation with the limiting arc groove. The limiting block cooperates with the limiting arc groove to limit the rotation angle of the limiting baffle plate, and the pulling member is a tension spring, which is provided in the limiting arc groove, and is used to pull the limiting block to reset.

[0014] By adopting the above technical solution, the limit block and the limit arc groove can limit the limit baffle, reduce the occurrence of over-rotation of the limit baffle, improve the stability of the use of the limit baffle, and make the limit baffle more stable on the goods, thereby improving the convenience of using the limit baffle.

[0015] Preferably, an abutment surface is provided at one end of the limit baffle away from the chain plate. When the limit baffle is rotated, the abutment surface is perpendicular to the surface of the chain plate, and a limit surface abutting against the abutment surface is provided on the side wall of the rotating groove.

[0016] By adopting the above technical solution, the opening of the abutment surface can better increase the contact area between the goods and the limit baffle, reduce damage to the surface of the goods, and combined with the limit surface, it can support the limit block when the limit block is retracted into the rotating groove, thereby improving the ability of the limit block to withstand heavy objects and improving the effect of using the network chain.

[0017] Preferably, a sliding groove is provided on the chain plate to be plugged into the connecting belt, the depth of the sliding groove is consistent with the thickness of the connecting belt, and a plurality of rotating wheels are provided at the bottom of the sliding groove, and the axial direction of the rotating wheel is consistent with the axial direction of the second connecting wheel.

[0018] By adopting the above technical solution and opening a sliding groove, the connecting belt can slide more stably in the sliding groove, reducing the situation where the connecting belt is misaligned due to the goods, and improving the stability of the connecting belt. In combination with the use of a rotating wheel, it can not only reduce the friction between the connecting belt and the sliding groove, but also reduce the wear on the sliding groove, affecting the contact between the goods and the connecting belt, and improving the stability of the goods-driven transmission of the connecting belt.

[0019] Preferably, a friction surface is provided on the surface of the connecting belt.

[0020] By adopting the above technical solution, the friction surface can not only make the goods more convenient to drive the connecting belt to rotate, but also play a role in limiting the position of the goods when they move in multiple directions, thereby improving the stability of the goods fixation.

[0021] Preferably, a plurality of the rotation grooves are symmetrically arranged on the chain plate, and a plurality of the rotation grooves are opened obliquely toward the rotation direction of the chain plate along the center of the chain plate to both sides.

[0022] By adopting the above technical solution, several rotating grooves are opened symmetrically and tilted, which can converge the goods to the center of the chain plate when the goods slide, reduce the occurrence of goods detaching from the network chain, and improve the stability of the goods limit.

[0023] Preferably, a push groove is provided on the side of the rotating groove opposite to the transmission direction of the ring chain, the push groove is provided through the chain plate, a locking key is provided in the pushing groove for sliding, an elastic member is provided in the pushing groove for driving the locking key to move close to the limit baffle, an eccentric top block is provided on the side of the limit baffle close to the locking key, when the limit baffle is retracted into the rotating groove, the eccentric top block pushes the locking key to move toward the adjacent chain plate, and a locking groove is provided on the adjacent chain plate to engage with the locking key.

[0024] By adopting the above technical solution, during operation, when the limit block is retracted into the rotating groove, the locking key and the locking groove can better keep the surfaces of the two adjacent chain plates in the same plane, thereby improving the stability of cargo transportation; when passing through the transmission gear, the limit block is lifted up, so that the two adjacent chain plates can rotate, thereby making it more convenient to perform reciprocating motion, thereby improving the convenience and stability of the use of the network chain; and with such a design, the cooperation of the eccentric top block and the locking key can assist in lifting the limit block, and the heavier the weight, the better the limit block can be lifted up.

[0025] Preferably, locking blocks are provided on both sides of the locking key, the locking blocks are overlapped at the opening position of the pushing groove, and the elastic member is a compression spring, which is provided on the locking block and the side wall of the rotating groove.

[0026] By adopting the above technical solution, the locking block can be used to limit the locking key, thereby reducing the situation where the locking key is separated from the pushing groove and improving the stability of using the locking key.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. During operation, the ring chain is conveying normally. The worker places the goods on the chain plate. Under the action of inertia or gravity, the goods slide on the chain plate, and the goods drive the connecting belt to rotate, thereby driving the limit baffle to rotate out of the rotating groove, thereby achieving the purpose of restricting the movement of the goods, reducing the occurrence of goods slipping or reducing the distance of goods slipping. This design, on the one hand, can break through the requirements of fixed-interval blocking blocks for goods and improve the convenience of goods transportation. On the other hand, it can meet the support function of the goods, reduce the movement of goods due to self-friction under the action of inertia or gravity, and improve the stability of goods transportation;

[0029] 2. During operation, when the chain plate is transmitted to the transmission gear, it means that the goods have reached the end of the ring chain pair. At this time, the transmission gear and the limit baffle can support the goods, so that there is a gap between the goods and the ring chain, allowing workers to pick up the goods more conveniently and improving the convenience of cargo handling;

[0030] 3. During operation, when the limit block is retracted into the rotating groove, the locking key and the locking groove can better keep the surfaces of the two adjacent chain plates in the same plane, thereby improving the stability of cargo transportation. When passing through the transmission gear, the limit block is lifted up, so that the two adjacent chain plates can rotate, so that reciprocating motion can be performed more conveniently, thereby improving the convenience and stability of the network chain. And with such a design, the cooperation of the eccentric top block and the locking key can assist in lifting the limit block. When the weight is heavier, the limit block can be better lifted up.

[0033] The following is combined with Figure 1 - Figure 8This application is described in further detail.

[0034] The embodiment of the present application discloses a heavy-load network chain.

[0035] Example 1

[0036] Reference Figure 1 A heavy-load mesh chain includes a ring chain composed of multiple mesh chain units. The mesh chain unit is composed of two hinged chain plates 1. Multiple hinge seats 5 are arranged between adjacent chain plates 1. A hinge cavity is formed between adjacent hinge seats 5. A hinge rod 6 is inserted into the hinge seat 5. The hinge rod 6 is also provided with multiple hinge seats 5, so that the adjacent chain plates 1 can be rotated more conveniently. One of the chain plates 1 is provided with a rotation groove 4, in which a limit baffle 3 is rotatably connected. When the limit baffle 3 rotates in the rotation groove 4, the side of the limit baffle 3 away from the chain plate 1 is flush with the surface of the chain plate 1, and the limit baffle 3 is rotated out to support the cargo. A first connecting wheel 11 is fixed to the side wall of the limit baffle 3. A plurality of second connecting wheels 7 are rotatably connected to the adjacent chain plates 1 in the transmission direction of the endless chain. A connecting belt 2 is sleeved between the first connecting wheel 11 and the second connecting wheel 7. The upper surface of the connecting belt 2 is flush with the surface of the chain plate 1. A pulling member 8 is fixed in the rotation groove 4 for driving the limit baffle 3 to return to its original position. This allows the connecting belt 2 to rotate when the cargo slips, causing the limit baffle 3 to rotate out of the rotation groove 4, limiting the cargo's position, reducing the distance the cargo moves, and improving the convenience of cargo transportation. A plurality of rotating grooves 4 are symmetrically opened on the chain plate 1, and a plurality of rotating grooves 4 are opened inclined toward the rotation direction of the chain plate 1 along the center of the chain plate 1 to both sides; adopting such a design, the plurality of rotating grooves 4 can form a V-shaped structure, so that the goods can better converge to the center of the chain plate 1, thereby improving the convenience and stability of cargo transportation.

[0037] The chain plate 1 has multiple transmission grooves 10 on its side near the transmission gear pair. These grooves mesh with the transmission gears and cooperate with the transmission gears to drive the endless chain transmission. The transmission grooves 10 are connected to the rotating groove 4, which is used to push the limit baffle 3 out. This allows the cargo to be lifted up when it reaches the end, making it easier for workers to retrieve the cargo and improving the convenience of handling heavy cargo. The limit baffle 3 has an arc-shaped support groove 14 on its side near the transmission gear, which plugs into the transmission gear. This allows the pressure on the limit baffle 3 to better act on the transmission gear, reducing the pressure on the transmission connection of the limit baffle 3 and ensuring the service life of the limit baffle 3.

[0038] A limit arc groove 12 is defined on the side wall of the rotation groove 4. A limit block 13 is fixed to the side wall of the limit baffle 3, which slides in engagement with the limit arc groove 12. The limit block 13 engages with the limit arc groove 12 to limit the rotation angle of the limit baffle 3. The pulling member 8 is a tension spring installed in the limit arc groove 12. The tension spring is used to pull the limit baffle 3 back to its original position, thereby improving the convenience of retracting the limit baffle 3 into the rotation groove 4. An abutment surface 16 is defined on the end of the limit baffle 3 away from the chain plate 1. When the limit baffle 3 rotates, the abutment surface 16 is perpendicular to the surface of the chain plate 1. A limit surface 15 is defined on the side wall of the rotation groove 4, which abuts against the abutment surface 16. The limit surface 15 is inclined along the depth direction of the rotation groove 4 toward the limit baffle 3, thereby limiting the limit baffle 3 through the cooperation of the limit surface 15 and the abutment surface 16, thereby improving the stability of the limit baffle 3 when in use.

[0039] The chain plate 1 is provided with a sliding groove 17 that is plugged into the connecting belt 2. The depth of the sliding groove 17 is consistent with the thickness of the connecting belt 2. A plurality of rotating wheels 24 are fixed to the bottom of the sliding groove 17. The axial direction of the rotating wheel 24 is consistent with the axial direction of the second connecting wheel 7. This allows the connecting belt 2 to slide more stably in the sliding groove 17, reducing the situation where the connecting belt 2 is misaligned due to the cargo, and improving the stability of the use of the connecting belt 2. In combination with the use of the rotating wheel 24, not only can the friction between the connecting belt 2 and the sliding groove 17 be reduced, but also the wear on the sliding groove 17 can be reduced, which affects the contact between the cargo and the connecting belt 2, and improves the stability of the cargo-driven transmission of the connecting belt 2. The surface of the connecting belt 2 is formed with a friction surface 25, which is composed of multiple protrusions, so that the cargo can better drive the transmission of the connecting belt 2, improving the convenience of using the connecting belt 2.

[0040] The implementation principle of a heavy-duty network chain in an embodiment of the present application is as follows: during operation, the ring chain transmits normally. When the goods are placed on the chain plate 1, when the goods slide, the connecting belt 2 is driven to rotate, thereby driving the limit baffle 3 to rotate out of the rotation groove 4, thereby limiting the goods. On the one hand, it can break through the requirements of the fixed-interval blocking blocks for the goods and improve the convenience of goods transportation. On the other hand, it can meet the supporting role for the goods, reduce the movement caused by the goods overcoming their own friction due to inertia or gravity, and improve the stability of goods transportation; when the goods reach the end, the limit baffle 3 can support the goods and lift the goods, so that the staff can pick up the goods more conveniently, thereby improving the convenience of goods handling.

[0041] Example 2

[0042] Reference Figure 6This embodiment differs from the first embodiment in that a push groove 21 is defined on the side of the rotating groove 4 opposite the transmission direction of the endless chain. This push groove 21 is a rectangular groove extending through the chain plate 1. A locking key 20 is slidably connected within the push groove 21. Locking blocks 23 are integrally formed on either side of the locking key 20 and overlap the opening of the push groove 21. An elastic member 22 is disposed within the push groove 21 for driving the locking key 20 toward the limit baffle 3. The elastic member 22 is a compression spring fixed to the locking blocks 23 and the sidewall of the rotating groove 4, thereby more conveniently supporting the locking key 20 toward the limit baffle 3. An eccentric push block 19 is integrally formed on the side of the limit baffle 3 near the locking key 20. When the limit baffle 3 is retracted into the rotating groove 4, the eccentric push block 19 pushes the locking key 20 toward the adjacent chain plate 1. The adjacent chain plate 1 has a locking groove 26 that engages with the locking key 20.

[0043] The working principle of Example 2 is as follows: the locking key 20 cooperates with the locking slot 26 to better align two adjacent chain plates 1 with each other, improving the convenience of chain plate 1 in transporting goods. When passing through the transmission gear, the limit baffle 3 is lifted, allowing the two adjacent chain plates 1 to rotate, thereby more conveniently performing reciprocating motion and improving the convenience and stability of the mesh chain. In addition, with this design, the cooperation between the eccentric top block 19 and the locking key 20 can assist in lifting the limit block, and the heavier the load, the better the limit block 13 can be lifted.

[0044] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
