Description

Technical Field

[0001] This utility model belongs to the field of logistics equipment technology and relates to a container transport platform. Background Technology

[0002] To facilitate loading and unloading goods into and out of containers, goods are typically placed on pallets first, and then forklifts are used to push the pallets into and pull them out of the container. Because the side walls of standard shipping containers are made of corrugated steel sheets, the front ends of the pallets can easily get stuck in the corrugated sheets when loading the container, preventing loading from being completed. This also makes it very easy for the front ends of the pallets to damage or even cut the corrugated sheets, thus damaging the container.

[0003] To this end, patent application publication number CN109747928A discloses a built-in cargo pallet and a container having the same. The front end of the pallet is provided with guide wheel devices on both sides facing the side panel. The pallet can move along the side panel inside the container. The guide wheel device includes multiple guide wheels arranged in a line along the longitudinal direction of the pallet. When the pallet moves inside the container, at least one of the multiple guide wheels is always located within the crest section of the side panel.

[0004] The aforementioned transport pallet achieves smooth entry and exit from containers by setting multiple longitudinal guide wheels on both sides of one longitudinal end, but there are still shortcomings: during transportation, the longitudinal end of the transport pallet is limited by the container door and container wall, the container door is more prone to deformation due to load bearing, resulting in movement, and the area on both sides of the transport pallet without guide wheels has a large gap space, which is prone to movement and tilting, resulting in unstable transportation. Summary of the Invention

[0005] This utility model addresses the aforementioned problems in existing technologies by providing a container transport plate. The technical problem this utility model aims to solve is that existing side guide wheel transport plates are unstable during transport within containers.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A container transport platform includes a rectangular frame, with several vertically arranged guide wheels rotatably connected to both sides of the frame. The guide wheels protrude from the horizontal sides of the frame. The platform is characterized in that it further includes a vertically arranged cylindrical bolt and a horizontally arranged top rod, with the top rod screwed through the bolt and one end extending out of the horizontal side of the frame.

[0008] Guide wheels provide guidance when the pallet enters and exits the container, ensuring smooth movement and preventing damage caused by rigid interference between the pallet and the corrugated plate of the container sidewall. Vertical bolts and horizontal push rods are installed on the lateral side of the frame, with the push rods screwed onto the bolts and one end extending beyond the lateral side of the frame. A positioning groove is provided on the frame, allowing the lower end of the bolt to be inserted into the groove and slide upwards outwards. Once the pallet is in place within the container, the push rods can be rotated to allow stepless outward feeding relative to the bolts. Based on the actual distance, the outer end of the push rod abuts against the inner sidewall of the container, eliminating the lateral gap between the pallet and the container's inner sidewall and preventing lateral movement. Simultaneously, the push rods act as a limit against the container's inner sidewall, constraining longitudinal movement of the pallet and maintaining its position relative to the container during transport.

[0009] In the aforementioned container pallet, the lower end of the bolt has a regular polygonal cross-section. The frame has an upward-facing positioning groove. The lower end of the bolt is inserted and circumferentially positioned within the positioning groove. The bolt is slidably connected to the lateral side of the frame and can move upward to disengage its lower end from the positioning groove. Because the inner wall of the container is corrugated, the push rod, when abutting against the inner wall, adapts to the inner wall of the corrugated groove at a certain angle, ensuring greater stability of the limiting position. Thus, after the pallet enters the container, the bolt can be slid upward according to its actual position to disengage its lower end from the positioning groove. Rotating the bolt further allows for multi-stage changes in the orientation of the outer end of the push rod to better adapt to the inner wall of the corrugated groove, thereby making the limiting position of the push rod more stable.

[0010] In the aforementioned container loading platform, the inner edge of the positioning groove has a number of teeth evenly arranged circumferentially, the number of which is an integer multiple of the number of sides at the lower end of the bolt. This allows for a wider range of angular selection for bolt positioning, enabling operators to choose a more suitable orientation and angle for the push rod to ensure stable positioning.

[0011] In the aforementioned container pallet, the transverse sidewalls of the frame have longitudinally arranged strip-shaped holes, through which the top rod passes. The vertical width of the strip-shaped hole is slightly larger than the diameter of the top rod. This allows for the use of the vertical space already occupied by the frame to arrange the bolts and top rods, reducing interference between the bolts and top rods and the cargo transported above the frame. It also facilitates the normal stacking of multiple frames when unloaded. The strip-shaped holes provide some clearance for the inclined top rods, and the inner edge of the holes provides vertical restraint, preventing the bolts from being dislodged from the positioning groove due to vibration during transport, thus preventing the restraint from failing.

[0012] In the aforementioned container transport platform, the axial cross-section of the bolt is inverted T-shaped, and the transverse side of the frame has horizontally arranged limiting plates spaced vertically. The upper end of the bolt passes through both limiting plates and can slide vertically relative to them. In this way, the two limiting plates provide constraint on the radial position of the bolt at two vertical points, thereby ensuring the stability of the bolt's vertical sliding direction. Simultaneously, the larger lower end dimension of the bolt helps reduce the force between the outer periphery of its lower end and the inner wall of the positioning groove when the bolt is subjected to torque, reducing the risk of deformation failure of the lower end of the bolt and the inner wall of the positioning groove.

[0013] In the aforementioned container pallet, at least two guide wheels are connected to both ends of the longitudinal direction of the transverse side of the frame. Since the spacing between the multiple guide wheels ensures that at least one guide wheel is in contact with the corrugated plate of the container sidewall or only has a certain gap, the presence of multiple guide wheels at both ends of the longitudinal direction of the frame restricts the lateral movement of the frame at its four corners. This limits the possibility of the entire frame tilting significantly relative to the container, ensuring stable transport of the pallet.

[0014] In the aforementioned container transport platform, there are at least two of each of the bolts, top rods, and positioning grooves, respectively arranged on both lateral sides of the frame. This allows the two top rods to be controlled to extend to corresponding lengths in different directions according to the actual intervals and insert into the corresponding corrugated grooves for locking, thus further locking the frame and subsequently the container, without requiring further movement or adjustment of the frame position.

[0015] Compared with the prior art, the advantages of this utility model are as follows:

[0016] After the pallet enters the container and is positioned, it can be controlled to feed outwards steplessly by rotating the top rod. Based on the actual distance between the position and the top rod, the outer end of the top rod abuts against the inner wall of the container, thereby eliminating the lateral gap between the pallet and the inner wall of the container and preventing the pallet from shifting laterally. At the same time, the top rod helps to form a limit with the inner wall of the container to restrain the longitudinal movement of the pallet, so that the pallet remains stable relative to the container during transportation.

[0024] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0025] like Figure 1-6 As shown, this container transport platform includes a rectangular frame 1. The inner side of the transverse side panels of the frame 1 has a weight-reducing hollow space. Four vertically arranged guide wheels 2 are rotatably connected to both sides of the transverse side of the frame 1. The guide wheels 2 protrude from the transverse side of the frame 1. The transport platform also includes four vertically arranged cylindrical anchors 3 and four horizontally arranged top rods 4. The top rods 4 are screwed through the anchors 3 and one end extends out of the transverse side of the frame 1. The lower end of the anchor 3 has a regular hexagonal cross-section. The frame 1 has an upward-facing positioning groove 11. The lower end of the anchor 3 is inserted and circumferentially positioned in the positioning groove 11. The anchor 3 is slidably connected to the transverse side of the frame 1 and can move upward so that the lower end of the anchor 3 can disengage from the positioning groove 11. Specifically, the inner edge of the positioning groove 11 has twelve circumferentially evenly arranged locking teeth 111. The transverse sidewall of frame 1 has longitudinally arranged strip holes 12, through which the top rod 4 passes. The vertical width of the strip holes 12 is slightly larger than the diameter of the top rod 4. The axial cross-section of the bolt 3 is inverted T-shaped. Each bolt 3 has two horizontally arranged limiting plates 13 spaced vertically on the transverse side of frame 1. The upper end of the bolt 3 passes through the two limiting plates 13 and can slide vertically relative to the limiting plates 13. Two guide wheels 2 are connected to the longitudinal ends of the transverse sidewall of frame 1. Each set of guide wheels 2 is provided with a bolt 3, a top rod 4, and a positioning groove 11.

[0026] After the transport plate is fed into the container, the outward feed length of each top rod 4 can be controlled according to the actual distance between the lateral side and the inner wall of the container. This allows the outer end of the top rod 4 to abut against the inner wall of the container to form a lateral limit. At the same time, the orientation of the top rod 4 can be adjusted by pre-adjusting the circumferential angle of the bolt 3, so that the top rod 4, which passes horizontally through the bolt 3, can change downward to match the angle of the corrugated groove wall of the corresponding inner wall of the container, thus improving the longitudinal limit effect. The rotation of the top rod 4 can be carried out in the space inside the lateral side of the frame 1. This space is usually not obstructed by cargo, ensuring smooth operation and stable limit.
