Description

Technical Field

[0001] This utility model relates to the field of locking device technology, specifically a pallet locking device applied to self-loading and unloading vehicles. Background Technology

[0002] Currently, trucks use containers and pallets to transport goods. Containers are used to load goods, and pallets are used to place containers. As the pressure of logistics transportation continues to increase, the requirements for the time required for the unfolding and unloading of the entire vehicle are becoming increasingly stringent. With the deepening of automation, the generalization and integration of loading and unloading of goods during transportation also need to be further strengthened. Containers usually need to be paired with pallets to achieve rapid self-loading and unloading operations in the process of automatic loading and unloading. Therefore, the limiting and fixing devices of pallets in the self-loading and unloading process need further research.

[0003] Because container pallets need to be untied during container unloading so that the container can slide down at an angle to complete the unloading, and most current pallet locking devices require manual unlocking, this increases the time spent loading and unloading containers and reduces the efficiency of logistics transportation.

[0004] Based on this, this solution proposes a pallet locking device for self-loading and unloading vehicles. Utility Model Content

[0005] The purpose of this invention is to provide a pallet locking device for self-loading and unloading vehicles to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pallet locking device for self-loading and unloading vehicles, comprising a first pallet and a second pallet, the first pallet and the second pallet being connected by a spring hinge, a connecting assembly being provided between the first pallet and the second pallet, the connecting assembly comprising a housing, a cylinder, a first sliding plate, a first spring, a second sliding plate and a chain, the housing being fixedly connected to the second pallet, the cylinder being fixedly connected inside the housing, the first sliding plate and the second sliding plate being slidably connected inside the housing, the first spring being fixedly connected between the first sliding plate and the second sliding plate, the first sliding plate being fixedly connected to the output shaft of the cylinder, one end of the chain being fixedly connected to the second sliding plate, the other end of the chain being fixedly connected to the first pallet, and a locking assembly being provided between the first pallet and the second pallet.

[0007] Preferably, the locking assembly includes a fixed sleeve, a slider, and a second spring. The fixed sleeve is fixedly connected to the first tray, the slider is slidably connected to the fixed sleeve, and the second spring is fixedly connected between the fixed sleeve and the slider.

[0008] Preferably, the locking assembly further includes a groove and a fixing rod, the groove being formed on the slider and the fixing rod being fixedly connected to the second tray.

[0009] Preferably, the locking assembly further includes a movable rod, a first magnetic block, and a second magnetic block. The movable rod is fixedly connected to the first sliding plate, the first magnetic block is fixedly connected to the movable rod, and the second magnetic block is fixedly connected to the slider.

[0010] Preferably, the movable rod is slidably connected to the housing and the second sliding plate, and the movable rod passes through the housing and the second sliding plate.

[0011] Preferably, the groove is adapted to the fixing rod, and the first magnetic block and the second magnetic block attract each other.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. When the cylinder's output shaft extends, the chain moves towards the first pallet. At this time, the first pallet bends downward due to its own weight. When the cylinder's output shaft retracts, the chain is pulled into the housing, and the first pallet is pulled upward, causing the first and second pallets to join together. When the first and second pallets are joined together, the first and second magnetic blocks will attract each other. At this point, if the cylinder's output shaft retracts further, the first sliding plate will move closer to the cylinder. Since the chain is already taut, the second sliding plate will not move. The first spring is stretched, but the movement of the first sliding plate will drive the moving rod to move, thereby moving the moving rod and the first magnetic block on it. The second magnetic block attracts the first magnetic block, and the attraction is greater than the elastic force of the second spring. Therefore, the second magnetic block and the slider will move together with the first magnetic block, causing the groove on the slider to fit onto the fixed rod. At this time, the slider and the fixed rod are embedded together, and the first and second pallets cannot bend relative to each other. Therefore, the first and second pallets are locked together, jointly supporting the container above.

[0014] 2. When container unloading is required, the output shaft of the cylinder extends, causing the first and second magnetic blocks to move, so that the slider and the fixed rod separate. At this time, the first pallet can bend downward. When the output shaft of the cylinder continues to extend, the chain begins to move towards the first pallet, and the first pallet will bend downward. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides a technical solution: a pallet locking device for self-loading and unloading vehicles, including a first pallet 1 and a second pallet 2, the first pallet 1 and the second pallet 2 are connected by a spring hinge 3, and a connecting assembly 4 is provided between the first pallet 1 and the second pallet 2, the connecting assembly 4 including a housing 41, a cylinder 42, a first sliding plate 43, a first spring 44, a second sliding plate 45 and a chain 46, the housing 41 is fixedly connected to the second pallet 2, the cylinder 42 is fixedly connected to the inside of the housing 41, the first sliding plate 43 and the second sliding plate 45 are slidably connected to the inside of the housing 41, and the first spring 44 is fixedly connected to the second pallet 2. Between a sliding plate 43 and a second sliding plate 45, the first sliding plate 43 is fixedly connected to the output shaft of the cylinder 42, one end of the chain 46 is fixedly connected to the second sliding plate 45, and the other end of the chain 46 is fixedly connected to the first tray 1. When the chain 46 moves toward the first tray 1, the first tray 1 can be bent downwards, causing the first tray 1 and the second tray 2 to separate. When the chain 46 is pulled toward the second tray 2, the first tray 1 will be pulled up, causing the first tray 1 and the second tray 2 to be spliced ​​together, and the chain 46 will be taut at this time. A locking component 5 is also provided between the first tray 1 and the second tray 2.

[0023] The locking assembly 5 includes a fixed sleeve 51, a slider 52, and a second spring 53. The fixed sleeve 51 is fixedly connected to the first tray 1, the slider 52 is slidably connected to the fixed sleeve 51, and the second spring 53 is fixedly connected between the fixed sleeve 51 and the slider 52.

[0024] The locking assembly 5 also includes a groove 54 and a fixing rod 55. The groove 54 is formed on the slider 52, and the fixing rod 55 is fixedly connected to the second tray 2. When the first tray 1 and the second tray 2 are spliced ​​together, the slider 52 will approach the fixing rod 55, but the slider 52 is not fitted onto the fixing rod 55. At this time, the first tray 1 and the second tray 2 are not locked. When the first tray 1 is subjected to gravity, it will tend to bend downwards, and the force will be transmitted to the chain 46, the first slide plate 43 and the output shaft of the cylinder 42. Therefore, locking is required when keeping the first tray 1 and the second tray 2 spliced ​​together.

[0025] The locking assembly 5 also includes a moving rod 56, a first magnetic block 57, and a second magnetic block 58. The moving rod 56 is fixedly connected to the first sliding plate 43, the first magnetic block 57 is fixedly connected to the moving rod 56, and the second magnetic block 58 is fixedly connected to the slider 52. When the first magnetic block 57 and the second magnetic block 58 attract each other, the attraction force is greater than the elastic force of the second spring 53. Therefore, as long as the second magnetic block 58 moves with the first magnetic block 57, the slider 52 can move towards the fixed rod 55, so that the fixed rod 55 is embedded in the groove 54. At this time, the fixed rod 55 and the slider 52 are embedded together, and even if the first tray 1 is subjected to a downward force, the first tray 1 cannot be bent downward.

[0026] The movable rod 56 is slidably connected to the housing 41 and the second sliding plate 45, and the movable rod 56 passes through the housing 41 and the second sliding plate 45.

[0027] The groove 54 is adapted to the fixing rod 55. The first magnetic block 57 and the second magnetic block 58 attract each other. When the chain 46 is taut, the cylinder 42 moves the first slide plate 43, and the second slide plate 45 does not move. The first spring 44 is stretched at this time, and the moving rod 56 will drive the first magnetic block 57 to move. Then, the magnetic attraction force will move the second magnetic block 58 and the slider 52 so that the fixing rod 55 is embedded in the groove 54.

[0028] Working principle of this utility model:

[0029] Firstly, the first pallet 1 and the second pallet 2 can be separated by spring hinge 3. When the first pallet 1 and the second pallet 2 are put together, they are used to place the container. When the first pallet 1 is bent downwards, half of the container is suspended in the air. At this time, the container can be slid down at an angle with the transport vehicle for unloading and loading.

[0030] When the output shaft of cylinder 42 extends, chain 46 moves towards the first tray 1. At this time, the first tray 1 will bend downwards due to its own weight. When the output shaft of cylinder 42 retracts, chain 46 is pulled into the housing 41. At this time, the first tray 1 will also be pulled upwards, causing the first tray 1 and the second tray 2 to join together. When the first tray 1 and the second tray 2 are joined together, the first magnetic block 57 and the second magnetic block 58 will attract each other, realizing... Figure 4 In the state shown, if the output shaft of cylinder 42 is further retracted, the first slide plate 43 will move closer to cylinder 42. Since chain 46 is already taut, the second slide plate 45 will not move. The first spring 44 is stretched, but the movement of the first slide plate 43 will drive the moving rod 56 to move, thereby moving the moving rod 56 and the first magnetic block 57 on it. The second magnetic block 58 and the first magnetic block 57 attract each other, and the attraction is greater than the elastic force of the second spring 53. Therefore, the second magnetic block 58 and the slider 52 will move together with the first magnetic block 57, so that the groove 54 on the slider 52 fits onto the fixed rod 55. At this time, the slider 52 and the fixed rod 55 are embedded together, and the first tray 1 and the second tray 2 cannot be bent relative to each other. Therefore, the first tray 1 and the second tray 2 are locked together and jointly support the container above.

[0031] When container unloading is required, the output shaft of cylinder 42 is extended, causing the first magnetic block 57 and the second magnetic block 58 to move, so that the slider 52 and the fixed rod 55 are separated. At this time, the first pallet 1 can be bent downward. When the output shaft of cylinder 42 continues to extend, the chain 46 begins to move towards the first pallet 1, and the first pallet 1 will be bent downward.
