Abstract
Description
Technical Field
[0001] The embodiments of the present disclosure relate to the technical field of stacker trucks, and in particular, to a counterbalanced stacker truck. Background Art
[0002] Counterbalanced stacker trucks are commonly used material handling equipment in industrial logistics. Their core design revolves around "balanced stability" and offsets the overturning moment of cargo through a reasonable counterweight layout. They are widely used in warehouses, workshops, ports and other scenarios. When in use, the forks are controlled by hydraulic equipment to move up and down, and the forks are moved to the cargo by controlling the movement of the stacker truck. The cargo is then stacked on the forks, thereby adjusting the height and placing the cargo.
[0003] When transporting some regular objects, the goods placed on the forks are not easy to shake or fall over. However, when stacking some irregular objects, such as some soft objects or objects with side ropes, the ropes are usually hung on the forks to drive them to move. Therefore, the goods are easy to shake when moving. The existing stackers lack stabilizing devices on both sides. Therefore, when transporting irregular or soft goods, the porters need to slowly set up the stacker. Summary of the Invention

Therefore, they should not be understood as limitations on the present disclosure.
[0024] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.
[0025] like Figures 1 to 7 As shown, it shows a counterbalanced stacker in one embodiment of the present disclosure, including a body 1, a lifting seat 2 is slidably installed on the side of the body 1, and two forks 3 are fixedly installed on the side of the lifting seat 2, and also includes an adjustment plate 4, a rotating assembly, a stabilizing plate 5 and a cargo clamping assembly. There are two adjustment plates 4, both of which are set on the lifting seat 2 through a lifting assembly, and two rotating assemblies are set on the lifting assembly for rotating the adjustment plates 4. The sides of the two adjustment plates 4 are both installed with stabilizing plates 5 through electric cylinders 6, and the sides of the stabilizing plates 5 are both provided with cargo clamping assemblies.
[0026] like Figure 2 As shown, when transporting goods, the staff can control the movement of the vehicle body 1 through the controller of the vehicle body 1, and the hydraulic device and the sprocket chain on the vehicle body 1 can control the up and down movement of the lifting seat 2, thereby driving the fork 3 to move up and down. The staff can control this process through the controller. During the movement, the adjustment plate 4 and the stabilizing plate 5 are placed vertically to avoid obstruction caused by the stabilizing plate 5 and the adjustment plate 4 when the vehicle body 1 moves.
[0027] like Figure 5 and Figure 6 As shown, after the cargo is forked onto the fork 3, if the cargo on the fork 3 is relatively soft or irregular, the adjusting plate 4 and the stabilizing plate 5 are first rotated to a horizontal position by the rotating assembly. The rotating assembly includes a protective cover 15, a rotating gear ring 16, a second motor 17, a rotating gear 18 and a limit assembly. The side of the connecting frame 14 is detachably mounted with a protective cover 15, the rotating gear ring 16 is fixedly mounted on the rotating shaft 10, the second motor 17 is mounted on the side of the protective cover 15, the rotating gear 18 is coaxially connected to the output end of the second motor 17, and the rotating gear 18 is meshed with the rotating gear ring 16. The limit assembly is arranged on the protective cover 15, and the limit assembly includes a limit rod 19, a limit plate 20 and a limit block 21. The limit rod 19 is fixedly mounted on the side of the rotating shaft 10, the limit plate 20 is fixedly mounted on the side of the protective cover 15, and the limit block 21 is slidably mounted on the limit plate 20.
[0028] Specifically, the second motor 17 is started, and the output end of the second motor 17 drives the rotating gear 18 to rotate, and the rotating gear 18 drives the rotating gear ring 16 to rotate, and the rotating gear ring 16 drives the rotating shaft 10 to rotate, and the rotating shaft 10 drives the adjusting plate 4 to rotate to a horizontal position. Because a limiting groove is provided at the bottom end of the limit block 21, and the limiting groove is adapted to the top end of the limiting rod 19, and when the top end of the limiting rod 19 is inserted into the limiting groove of the limit block 21, the adjusting plate 4 is rotated to a horizontal position, the limit block 21 can be slid on the limiting plate 20, so that the bottom limiting groove of the limit block 21 is inserted into the top end of the limiting rod 19, thereby limiting the rotating shaft 10, avoiding the rotating shaft 10 from rotating when the goods are moved. Because the rotating gear 18 and the rotating gear ring 16 are both located in the protective cover 15, when the vehicle body 1 moves, the protective cover 15 can protect the engagement between the rotating gear ring 16 and the rotating gear 18.
[0029] like Figure 2 and Figure 3 As shown, after the rotation is completed, the stabilizing plate 5 can be driven to move above the fork 3 by the lifting assembly. The lifting assembly includes a support cover 7, a reciprocating screw 8, a first motor 11 and a synchronization assembly. Support covers 7 are fixedly installed on both sides of the lifting seat 2. The reciprocating screw 8 is rotatably installed in one of the support covers 7. A matching crescent slider 9 is installed on the reciprocating screw 8, and one of the adjustment plates 4 is rotatably installed on the side of the crescent slider 9 through a rotating shaft 10. The first motor 11 is installed on the support cover 7, and the output end of the first motor 11 is coaxially connected to the reciprocating screw 8. The synchronization assembly is arranged in the other support cover 7. The synchronization assembly includes a synchronization rod 12, a synchronization block 13 and a connecting frame 14. The synchronization rod 12 is fixedly installed in the other support cover 7, the synchronization block 13 is slidably installed on the synchronization rod 12, and the other adjustment plate 4 is rotatably installed on the side of the synchronization block 13 through the rotating shaft 10. The connecting frame 14 is set to be U-shaped, and the bottom end of the connecting frame 14 is fixedly mounted on the top of the crescent slider 9 and the synchronization block 13.
[0030] Specifically, the first motor 11 is started, and the output end of the first motor 11 drives the reciprocating screw 8 to rotate in the support cover 7. It should be added that the crescent slider 9 is installed on the reciprocating screw 8 through a reciprocating sleeve. The outer design of the crescent slider 9 matches the spiral groove of the reciprocating screw 8. When the reciprocating screw 8 rotates, the side wall of the spiral groove will generate an axial thrust on the crescent slider 9 embedded therein, and the crescent slider 9 can move along the axial trajectory of the reciprocating screw 8, thereby moving up and down. When the crescent slider 9 reaches the end of the reciprocating screw 8, the crescent slider 9 will smoothly transition to the reverse spiral groove, thereby realizing reciprocating movement, and a telescopic protective cover is installed on the outside of the reciprocating screw 8, which can protect the reciprocating screw 8.
[0031] Therefore, the crescent slider 9 moves up and down on the reciprocating screw 8, and driven by the connecting frame 14, the synchronous block 13 is synchronously raised and lowered on the synchronous rod 12, thereby driving the adjustment plate 4 to move up to the top of the fork 3, and then the electric cylinder 6 is started, and the electric cylinder 6 drives the stabilizing plate 5 to move forward to fit the side of the cargo. Because the two forks 3 are located between the two stabilizing plates 5, they can clamp both sides of the cargo on the forks 3, thereby preventing the cargo from tilting during subsequent movement.
[0032] like Figure 7 As shown, when transporting goods hung on the fork 3, the two ends of the goods can be blocked by the cargo clamping assembly. The cargo clamping assembly includes a clamping rod 22, a fixing plate 23 and a fixing rod 24. A sliding groove is provided on the side of the stabilizing plate 5, and two clamping rods 22 are slidably installed on the side of the stabilizing plate 5. Several fixing plates 23 are fixedly installed on the side of the stabilizing plate 5, and fixing holes are provided on the side of the fixing plate 23. Several fixing holes are provided on the side of the stabilizing plate 5, and the fixing rods 24 are adapted to the fixing holes of the stabilizing plate 5 and the fixing holes of the fixing plates 23.
[0033] Specifically, because a slide groove is provided on the side of the stabilizing plate 5, it should be added that both sides of the slide groove are open, so the clamping rod 22 can slide or be disassembled in the slide groove. When it is necessary to block the goods, the two clamping rods 22 can be slid into the slide groove of the stabilizing plate 5, and then the clamping rod 22 can be slid to the corresponding fixing plate 23 according to the width of the goods, and then the fixing rod 24 is inserted into the fixing hole of the fixing plate 23 and the clamping rod 22 to fix it. Therefore, the goods can be located between the four clamping rods 22. If it shakes during transportation, it will not shake much due to the blocking of the clamping rod 22, and it will not shake outside the fork 3.
[0034] Working principle: When transporting goods, first start the second motor 17, the output end of the second motor 17 drives the rotating gear 18 to rotate, the rotating gear 18 drives the rotating gear ring 16 to rotate, the rotating gear ring 16 drives the rotating shaft 10 to rotate, the rotating shaft 10 drives the adjustment plate 4 to rotate to a horizontal position, and then the limit block 21 is slid on the limit plate 20, so that the bottom limit groove of the limit block 21 is inserted into the top end of the limit rod 19, thereby limiting the rotating shaft 10 and preventing the rotating shaft 10 from rotating when the goods are moved.
[0035] Then start the first motor 11, and the output end of the first motor 11 drives the reciprocating screw 8 to rotate in the support cover 7, and the crescent slider 9 moves up and down on the reciprocating screw 8, and under the drive of the connecting frame 14, the synchronous block 13 is synchronously raised and lowered on the synchronous rod 12, thereby driving the adjustment plate 4 to move up to above the fork 3, and then start the electric cylinder 6, which drives the stabilizing plate 5 to move forward to fit the side of the cargo. Because the two forks 3 are located between the two stabilizing plates 5, they can clamp both sides of the cargo on the forks 3, thereby preventing the cargo from tilting during subsequent movement.
[0036] When carrying goods suspended on the forks 3, the two clamping rods 22 are slid into the sliding grooves of the stabilizing plate 5, and then the clamping rods 22 are slid to the corresponding fixing plates 23 according to the width of the goods. Then the fixing rods 24 are inserted into the fixing holes of the fixing plates 23 and the clamping rods 22 to fix them. The clamping rods 22 block the goods to prevent them from shaking too much.
[0037] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure and are not limiting. Although the present disclosure has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present disclosure may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present disclosure, and all of these should be included in the scope of the claims of the present disclosure.
