Description

Technical Field

[0001] The invention relates to the technical field of hydraulic lifts, and in particular to a hydraulic lift platform with a conveying mechanism. Background Art

[0002] In the process of some cargo production and processing, the cargo will be transported on the conveyor belt. Different processing techniques will cause the height of some conveyor belts to be different. There will be a certain height difference between two adjacent conveyor belts. Usually a hydraulic lift is set between the two conveyor belts, and adjacent conveying structures are set on the hydraulic lift. The cargo is transported from one conveyor belt to the hydraulic lift, and then the hydraulic lift rises to make the conveying structure rise to the same height as the other conveyor belt. Then the cargo is moved to the conveyor belt through the conveying structure for transportation again.

[0003] Since the hydraulic lift and the conveying structure are controlled by two different drive devices, when the control system fails, the conveying structure may cause the goods to move during the ascent process, which will cause the conveying structure to start conveying before the lift has risen to the required height, resulting in the failure to effectively transfer the goods. For this reason, we designed a hydraulic lift with a conveying mechanism. Summary of the invention

[0004] The hydraulic lifting platform with a conveying mechanism proposed by the present invention solves the above problems.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: A hydraulic lifting platform with a conveying mechanism comprises a base, two groups of scissor-type lifting frames are symmetrically installed on the upper surface of the base, a storage platform is installed on the upper ends of the two groups of scissor-type lifting frames, a limited position seat is fixed below the storage platform, and a limited position member is slidably installed below the storage platform, and the limited position member is connected to the scissor-type lifting frame; A plurality of equally spaced conveying rollers are rotatably mounted on the upper surface of the storage platform through a bearing seat, and the plurality of conveying rollers rotate synchronously through sprockets and chains, one of the conveying rollers is connected to the output shaft of a driving motor through a sprocket and a chain, and the driving motor is mounted on the side of the storage platform through a motor frame; A barrier structure for limiting the position of objects is installed on the right side surface of the storage table, and a driving mechanism is installed on the lower end surface of the storage table. The driving mechanism includes a downward pressing horizontal plate for driving the barrier structure to move downward, and a locking structure for locking the downward pressing horizontal plate.

[0006] Preferably, a lower translation rod and a fixed rod are rotatably inserted between the lower ends of the left and right sides of the two groups of scissor-type lifting frames, the lower translation rod is slidably connected to the left half of the base, the fixed rod is fixed to the right end of the base, and a pair of symmetrically distributed hydraulic cylinders are installed on the fixed rod, and the push rods of the hydraulic cylinders are connected to the lower translation rod; An upper translation rod is rotatably inserted between the upper ends of the left sides of the two groups of scissor-type lifting frames, and the upper translation rod is slidably connected to the left half of the lower surface of the storage platform, and the upper end of the right side of the scissor-type lifting frame is rotatably connected to the storage platform through an axle pin, and the front and rear ends of the left half of the base and the storage platform are penetrated by strip sliding holes, and the upper translation rod and the lower translation rod are respectively slidably placed in the corresponding strip sliding holes, so that the movement of the upper translation rod and the lower translation rod can be guided and limited, thereby improving the stability of the lifting of the scissor-type lifting frame; A lower supporting wheel is rotatably mounted on the front and rear ends of the lower translation rod, and an upper supporting wheel is rotatably mounted on the front and rear ends of the upper translation rod. The lower supporting wheel and the upper supporting wheel are in rolling contact with the surface of the base and the storage table respectively, and can be used to support the scissor-type lifting frame, increase its contact area with the base and the storage table, and facilitate its lifting.

[0007] Preferably, two moving rails are fixed on the lower surface of the storage table, and the limiting member includes a moving frame slidably installed under the two moving rails, and a connecting member is fixed on the left side of each of the two moving frames, and the connecting member is connected to the upper translation rod, and an unlocking plate is fixed to the right end of the rear moving frame. When the storage table is lifted, the scissor-type lifting frame will be unfolded or folded accordingly. When the scissor-type lifting frame is unfolded, the upper translation rod will move to the right, and the upper translation rod moving to the right will move the limiting member to the right through the connecting member, and the unlocking plate will gradually approach the locking structure and unlock the locking structure. A horizontal plate is fixed at the lower end between the two movable frames, and a lifting rod is inserted into the horizontal plate for sliding up and down, a limit block is fixed on the top of the lifting rod, and a lifting spring is sleeved on the lifting rod, and the two ends of the lifting spring are respectively abutted against the horizontal plate and the limit block, and the front and rear side surfaces of the limit seat are flush with the front and rear side surfaces of the limit block, a rectangular opening is opened on the horizontal plate, and the cross-section of the lifting rod is a rectangular structure, the lifting rod is slid up and down and inserted in the rectangular opening, and a circular ring is arranged at the bottom end of the lifting rod.

[0008] Preferably, a contact inclined surface is formed by cutting away a portion of the left surface of the limit seat, and a vertical surface is vertically arranged on the right surface of the limit seat; A lifting slope is formed on the left side surface of the limit block, and the left side surface of the limit block is vertically arranged to form a limit surface. When the limit block moves to the right, the lifting slope of the limit block will contact the contact slope of the limit seat and push the limit block to move downward. When the storage table is at the highest point, the limit block is located on the right side of the limit seat.

[0009] Preferably, the barrier structure comprises a longitudinal plate fixed longitudinally at the right end below the storage platform, a plurality of evenly distributed vertical rods are vertically fixed on the longitudinal plate, a lifting sleeve is slidably sleeved on the vertical rods, a lifting spring is sleeved on the vertical rods, and the upper and lower ends of the lifting spring are respectively in contact with the lifting sleeve and the longitudinal plate; A lifting plate is welded to the right side of the multiple lifting sleeves, and the left side surface of the lifting plate is in sliding contact with the right side surface of the storage table. A plurality of evenly distributed baffle columns are integrally formed on the top of the lifting plate. A downward pressure block is welded to the left side of the lifting plate, and a portion of the downward pressure block is cut away to the left to form a downward pressure inclined surface. The cross-section of the downward pressure block is a right-angled triangle structure, and there is a spacing between the bottom end of the lower pressure block and the upper surface of the longitudinal plate, which is greater than the spacing between the top of the baffle column and the upper surface of the outer ring of the conveying roller.

[0010] Preferably, a transverse rod is suspended and fixed under the storage table through a support, and two hanging rings are slidably sleeved on the transverse rod, and a downward pressing horizontal plate is fixed at the lower ends of the two hanging rings, and a downward pressing wheel is rotatably installed on the right surface of the downward pressing horizontal plate through an axle pin, and a release slope is formed by cutting off the leftmost part of the downward pressing horizontal plate, and three sets of locking grooves are formed on the front and rear sides of the left end of the downward pressing horizontal plate; The lower end of the storage table is screwed with a driving cylinder, and a driving block is installed on the push rod of the driving cylinder. The driving block is connected to the downward pressing horizontal plate. When the downward pressing horizontal plate is not locked, the push rod of the driving cylinder is extended to enable the downward pressing horizontal plate to move to the right along the transverse rod, and the downward pressing wheel will gradually approach the downward pressing block. When the lower pressure wheel continues to move to the right, the lower pressure wheel will move along the lower pressure inclined surface. At this time, the lower pressure block will be squeezed downward by the lower pressure wheel, and the lifting plate will move downward along the vertical rod until the lower pressure block contacts the longitudinal plate. At this time, the top of the barrier column is below the outer ring surface of the conveyor roller, and the object on the conveyor roller can be moved to the right and removed under the action of the conveyor roller.

[0011] Preferably, the locking structure includes two guide rods longitudinally fixed under the storage platform, the guide rods are slidably sleeved with locking blocks, and the two locking blocks are connected as a whole by a straight rod, and a pushing block for unlocking is fixed to the rear side of the locking block on the left side, and the upper surface of the pushing block is under the pressing cross plate, and the pushing block will not contact with the pressing cross plate to cause interference when moving forward and backward. When the pushing block moves forward and backward, it can drive the two locking blocks to move together, so that the locking blocks can be separated from the locking groove, and the pressing cross plate can be unlocked. At this time, the pressing cross plate can move to the right, so that the lifting plate can move downward; A fixing ring is sleeved and fixed on the guide rod, and a locking spring is sleeved on the guide rod. The front and rear ends of the locking spring are respectively connected to the fixing ring and the locking block. The locking spring makes the locking block always have a tendency to move backward. When the push rod of the driving cylinder returns to its original position, the locking block is just in front of the locking groove. When the pushing block is not affected by external forces other than the locking spring, the locking block and the pushing block will move backward under the action of the locking spring and be inserted into the locking groove, so that the downward pressing horizontal plate can be locked and cannot move. At this time, the lifting plate cannot move downward.

[0012] Preferably, a pushing slope is formed by cutting away a portion of the right side surface of the pushing block, and an unlocking slope is formed by designing a slope on the left side surface of the unlocking plate. When the limiting piece is at the rightmost end, the unlocking slope contacts the pushing slope. At this time, the limiting block is at the bottom, and the limiting block contacts the left end of the pressing horizontal plate. When the pressing horizontal plate moves to the right, the limiting block will move upward under the action of the lifting spring, thereby limiting the storage plate. When the pressing horizontal plate moves to the leftmost end, the releasing slope of the pressing horizontal plate will cause the limiting block to move upward. At this time, the limiting block is below the limiting seat, and the limiting piece can move to the left, and the storage table can be lowered.

[0013] The number of the locking grooves is greater than the number of locking blocks, and the left end of the leftmost locking block has an empty locking groove. The number of locking blocks and locking grooves is set according to actual needs, but the number of locking grooves is always one more than the number of locking blocks and is located on the left side of the locking block; When the downward pressing horizontal plate moves a unit distance to the right (that is, the distance between two adjacent locking grooves), the locking block will be locked into the locking groove under the action of the locking spring, thereby limiting the movement of the downward pressing horizontal plate, making it impossible for the lifting plate to descend, thereby avoiding the possibility of the lifting plate descending during the lifting process of the storage platform.

[0014] Beneficial effects of the present invention: 1. By setting a blocking structure at the right end of the storage platform and the conveying mechanism, the blocking structure is located above the conveying roller during the lifting process of the hydraulic lifting platform, which can block the right end of the conveying roller, thereby effectively preventing the movement of objects during the lifting process, thereby improving safety; 2. By setting a limit seat at the lower end of the storage platform, and connecting a limit piece to the scissor lift frame, in conjunction with the set driving mechanism, when the storage platform rises to the required height and the barrier structure is released, it can limit the lower end of the storage platform, so that the objects cannot fall during the transportation process; 3. The limit parts and the blocking structure are connected to the driving mechanism respectively, and the three cooperate with each other. When the storage table is raised or lowered, the blocking structure cannot move down to release the blocking. The storage table can only be raised or lowered when the blocking structure blocks again. The fault tolerance rate is improved because the storage table is raised or lowered when the blocking structure blocks due to a fault. BRIEF DESCRIPTION OF THE DRAWINGS

The driving mechanism 7 includes a downward pressing horizontal plate 72 for driving the barrier structure 6 to move downward, and a locking structure 73 for locking the downward pressing horizontal plate 72.

[0019] Reference Figure 1 - Figure 3 A lower translation rod 21 and a fixed rod 23 are respectively rotatably inserted between the lower ends of the left and right sides of the two groups of scissor lifts 2. The lower translation rod 21 is slidably connected to the left half of the base 1. The fixed rod 23 is fixed to the right end of the base 1. A pair of symmetrically distributed hydraulic cylinders 3 are installed on the fixed rod 23. The push rods of the hydraulic cylinders 3 are connected to the lower translation rod 21. An upper translation rod 25 is rotatably inserted between the upper ends of the left sides of the two groups of scissor-type lifting frames 2, and the upper translation rod 25 is slidably connected to the left half of the lower surface of the storage platform 4, and the upper end of the right side of the scissor-type lifting frame 2 is rotatably connected to the storage platform 4 through an axle pin. The front and rear ends of the left half of the base 1 and the storage platform 4 are penetrated by strip sliding holes, and the upper translation rod 25 and the lower translation rod 21 are respectively slidably placed in the corresponding strip sliding holes, so that the movement of the upper translation rod 25 and the lower translation rod 21 can be guided and limited, thereby improving the stability of the lifting of the scissor-type lifting frame 2; A lower supporting wheel 22 is rotatably mounted on the front and rear ends of the lower translation rod 21, and an upper supporting wheel 24 is rotatably mounted on the front and rear ends of the upper translation rod 25. The lower supporting wheel 22 and the upper supporting wheel 24 are in rolling contact with the surface of the base 1 and the storage table 4 respectively, and can be used to support the scissor-type lifting frame 2, increase its contact area with the base 1 and the storage table 4, and facilitate its lifting.

[0020] Reference Figure 2 - Figure 6Two moving rails 42 are fixed on the lower surface of the storage table 4, and the limiting member 43 includes a moving frame 432 slidably installed under the two moving rails 42, and a connecting member 431 is fixed on the left side of the two moving frames 432 respectively. The connecting member 431 is connected to the upper translation rod 25, and an unlocking plate 438 is fixed to the right end of the rear moving frame 432. When the storage table 4 is lifted or lowered, the scissor-type lifting frame 2 will be unfolded or folded accordingly. When the scissor-type lifting frame 2 is unfolded, the upper translation rod 25 will move to the right. The upper translation rod 25 moving to the right will move the limiting member 43 to the right through the connecting member 431, and the unlocking plate 438 will gradually approach the locking structure 73 and unlock the locking structure 73. A horizontal plate 433 is fixed at the lower end between the two moving frames 432, and a lifting rod 434 is inserted into the horizontal plate 433 for sliding up and down. A limit block 436 is fixed to the top of the lifting rod 434, and a lifting spring 435 is sleeved on the lifting rod 434. The two ends of the lifting spring 435 are respectively abutted against the horizontal plate 433 and the limit block 436. The front and rear side surfaces of the limit seat 41 are flush with the front and rear side surfaces of the limit block 436. A rectangular opening is opened on the horizontal plate 433, and the cross-section of the lifting rod 434 is a rectangular structure. The lifting rod 434 is inserted into the rectangular opening for sliding up and down, and a circular ring is arranged at the bottom end of the lifting rod 434. The lifting rod 434 can move up and down in the rectangular opening without deflection, and the design of the circular ring can ensure the maximum rising position of the lifting rod 434, and ensure that the limit block 436 can contact the limit seat 41 and slide downward.

[0021] A contact inclined surface 411 is formed by cutting away a portion of the left surface of the limiting seat 41, and a vertical surface is vertically arranged on the right surface of the limiting seat 41; A lifting slope 437 is formed on the left side surface of the limit block 436, and the left side surface of the limit block 436 is vertically arranged to form a limiting surface. When the limit block 436 moves to the right, the lifting slope 437 of the limit block 436 will contact the contact slope 411 of the limit seat 41 and push the limit block 436 to move downward. When the storage table 4 is at the highest point, the limit block 436 is located on the right side of the limit seat 41.

[0022] Reference Figure 2 , Figure 3 , Figure 7 as well as Figure 8 The barrier structure 6 includes a longitudinal plate 64 longitudinally fixed to the right end below the storage platform 4, and a plurality of evenly distributed vertical rods 65 are vertically fixed on the longitudinal plate 64. The vertical rods 65 are slidably sleeved with a lifting sleeve 611, and a lifting spring 66 is sleeved on the vertical rods 65. The upper and lower ends of the lifting spring 66 are respectively in contact with the lifting sleeve 611 and the longitudinal plate 64; A lifting plate 61 is welded to the right side of the multiple lifting sleeves 611, and the left side surface of the lifting plate 61 is in sliding contact with the right side surface of the storage platform 4. A plurality of evenly distributed blocking columns 62 are integrally formed at the top of the lifting plate 61, and a downward pressing block 63 is welded on the left side of the lifting plate 61. The downward pressing block 63 is partially cut away on the left side to form a downward pressing inclined surface 631. The cross-section of the downward pressing block 63 is a right-angled triangle structure, and the jacking spring 66 always makes the lifting plate 61 have an upward force. When the lifting plate 61 is not affected by external forces other than its own gravity, the jacking spring 66 makes the lifting plate 61 at the top. At this time, the top of the blocking column 62 is above the outer ring surface of the conveying roller 5, and there is a distance between the bottom end of the lower pressing block 63 and the upper surface of the longitudinal plate 64, which is greater than the distance between the top of the blocking column 62 and the upper surface of the outer ring surface of the conveying roller 5. When the lifting plate 61 moves downward, the blocking column 62 can be below the outer ring surface of the conveying roller 5, thereby facilitating the object on the conveying roller 5 to be moved to the right and taken out.

[0023] Reference Figure 4 - Fig. 9 , a traverse rod 74 is suspended and fixed under the storage platform 4 through a support, and two hanging rings are slidably sleeved on the traverse rod 74, and a downward pressing horizontal plate 72 is fixed at the lower ends of the two hanging rings. A downward pressing wheel 721 is rotatably mounted on the right surface of the downward pressing horizontal plate 72 through an axle pin, and a release inclined surface 723 is formed by cutting off the leftmost part of the downward pressing horizontal plate 72, and three sets of locking grooves 722 are formed on the front and rear sides of the left end of the downward pressing horizontal plate 72; The lower end of the storage platform 4 is screwed with a driving cylinder 71, and a driving block 711 is installed on the push rod of the driving cylinder 71, and the driving block 711 is connected to the downward pressing cross plate 72. When the downward pressing cross plate 72 is not locked, the push rod of the driving cylinder 71 is extended to enable the downward pressing cross plate 72 to move rightward along the transverse rod 74, and the lower pressing wheel 721 will gradually approach the lower pressing block 63. When the lower pressing wheel 721 continues to move to the right, the lower pressing wheel 721 will move along the downward pressing inclined surface 631. At this time, the lower pressing block 63 will be squeezed downward by the lower pressing wheel 721, and the lifting plate 61 will move downward along the vertical rod 65 until the lower pressing block 63 contacts the longitudinal plate 64. At this time, the top of the blocking column 62 is below the outer ring surface of the conveying roller 5, and the object on the conveying roller 5 can be moved to the right and removed under the action of the conveying roller 5; When the downward pressing plate 72 moves to the left, the limit block 436 will move upward under the action of the lifting spring 435, and the limit block 436 will be unable to move to the left due to the action of the limit seat 41, and the storage table 4 will be restricted and unable to move downward; When the push rod of the driving cylinder 71 contracts, the lower pressure wheel 721 will move to the left, and the lower pressure wheel 721 will move away from the lower pressure block 63. The lifting spring 66 will push the lifting plate 61 to move up and stay in place, thereby limiting the object and preventing it from falling off.

[0024] When the locking mechanism 73 is in the state of being lifted up, the locking block 732 is in the state of being slidable forward and backward and is in the state of being lifted up, so that the locking block 732 can be pulled out of the locking groove 722 to unlock the downward-pressing cross plate 72. When the locking cam 732 is in the state of being moved backwards, the locking cam 732 will be in the state of being moved backwards, and the locking cam 732 will be in the state of being moved backwards.

[0025] The right side surface of the pushing block 735 is cut away to form a pushing inclined surface 736, and the inclined surface of the left side surface of the unlocking plate 438 is designed to form an unlocking inclined surface 439. When the limit member 43 is at the rightmost end, the unlocking inclined surface 439 contacts the pushing inclined surface 736. At this time, the limit block 436 is at the bottom, and the limit block 436 contacts the left end of the pressing horizontal plate 72. When the pressing horizontal plate 72 moves to the right, the limit block 436 will move upward under the action of the lifting spring 435, thereby limiting the storage plate 4. When the pressing horizontal plate 72 moves to the leftmost end, the release inclined surface 723 of the pressing horizontal plate 72 will cause the limit block 436 to move upward. At this time, the limit block 436 is below the limit seat 41, and the limit member 43 can move to the left, and the storage table 4 can be lowered.

[0026] The number of locking slots 722 is greater than the number of locking blocks 732, and the left end of the leftmost locking block 732 has an empty locking slot 722. The number of locking blocks 732 and locking slots 722 is set according to actual needs, but the number of locking slots 722 is always one more than the number of locking blocks 732, and is located on the left side of the locking block 732. Fig. 9When the locking plate 732 is in the unlocked position, the locking plate 738 will be in the unlocked position, and the locking plate 739 will be in the unlocked position when the locking plate 738 is in the unlocked position.

[0027] Working principle: after the goods are transported from the left to the hydraulic lifting platform, the conveying roller 5 on the storage platform 4 moves the goods to the right under the action of the driving motor 51. After the goods move to the rightmost end of the conveying roller 5 on the storage platform 4, the push rod of the hydraulic cylinder 3 contracts, the scissor lift 2 unfolds and makes the storage platform 4 rise. During this process, the upper translation rod 25 moves to the right. The upper translation rod 25 moving to the right will make the limit member 42 move to the right through the connecting member 431, and the unlocking plate 438 will gradually approach the pushing block 735 and make it move to the right. When the limit block 436 moves to the right, the lifting inclined surface 437 of the limit block 436 will contact the contact inclined surface 411 of the limit seat 41 and push the limit block 436 to move downward; When the storage platform 4 is at the highest point, the upper translation rod 25 moves to the rightmost end, the limit block 436 is located on the right side of the limit seat 41, the limit block 436 is at the bottom, and the limit block 436 contacts the left end of the downward pressing horizontal plate 72, the push block 735 moves forward to drive the two locking blocks 732 to move together, so that the locking block 732 can be disengaged from the locking groove 722, and the downward pressing horizontal plate 72 can be unlocked; After that, the push rod of the driving cylinder 71 is extended to make the downward pressing cross plate 72 move rightward along the transverse rod 74, and the lower pressing wheel 721 will gradually approach the lower pressing block 63. When the lower pressing wheel 721 continues to move rightward, the lower pressing wheel 721 will move along the downward pressing inclined surface 631. At this time, the lower pressing block 63 will be squeezed downward by the lower pressing wheel 721, and the lifting plate 61 will move downward along the vertical rod 65 until the lower pressing block 63 contacts the longitudinal plate 64. At this time, the top end of the barrier column 62 is below the outer ring surface of the conveying roller 5, and the object on the conveying roller 5 can be moved rightward to the conveyor belt on the right side under the action of the conveying roller 5. When the downward pressing cross plate 72 moves to the right, the limit block 436 will move upward under the action of the elastic force of the lifting spring 435. At this time, the limit block 436 is engaged with the limit seat 41, and the limit block 436 cannot move to the left due to the action of the limit seat 41. Since the upper translation rod 25 and the limit block 436 move left and right synchronously, when the limit block 436 cannot move to the left, the upper translation rod 25 cannot move to the left either, so that the storage table 4 will be restricted and cannot move downward; When the push rod of the driving cylinder 71 contracts, the lower pressure wheel 721 will move leftward therewith, and the lower pressure wheel 721 will move away from the lower pressure block 63, and the lifting spring 66 will push the lifting plate 61 to move up and be in the original position, thereby limiting the object. When the lower pressure cross plate 72 moves to the leftmost end, the release inclined surface 723 of the lower pressure cross plate 72 will make the limit block 436 move downward, so that the limit block 436 is under the limit seat 41, and the limit member 43 can move leftward, and the storage platform 4 can be lowered. At this time, the locking block 732 is facing the locking groove 722; When the storage platform 4 descends, the lower translation rod 25 moves to the left, the unlocking plate 439 moves away from the pushing block 735, and the locking block 732 will be clamped into the locking groove 722 under the action of the locking spring 734, thereby limiting the movement of the downward pressing cross plate 72, making it impossible for the lifting plate 61 to descend, avoiding the possibility of the lifting plate 61 descending during the lifting of the storage platform 4.

[0028] By arranging a blocking structure 6 at the right end of the storage platform 4 and the conveying mechanism, the blocking structure 6 is located above the conveying roller 5 during the lifting process of the hydraulic lifting platform, and can block the right end of the conveying roller 5, thereby effectively preventing the object from moving during the lifting process, thereby improving safety; By setting a limit seat 41 at the lower end of the storage platform 4, and connecting a limit member 43 to the scissor lift frame 2, and cooperating with the drive mechanism 7, when the storage platform 4 rises to a required height and the barrier structure 6 releases the barrier, it can limit the lower end of the storage platform 4, so that the object cannot fall during the transportation process; The limit member 43 and the blocking structure 6 are connected to the driving mechanism 7 respectively, and the three cooperate with each other. When the storage table 4 is raised or lowered, the blocking structure 6 cannot move down to release the blocking. The storage table can be raised or lowered only when the blocking structure 6 blocks again. The fault tolerance rate is improved because the storage table 4 is raised or lowered when the blocking structure 6 does not block due to a fault.
