Description

Technical Field

[0001] The utility model relates to the field of container auxiliary devices, in particular to a door end ramp suitable for a container locking rod door. Background Art

[0002] The ramp in the prior art is placed at the door end of the container to provide a passage for transporting goods inside and outside the container. However, the existing ramp is narrow and is only suitable for small cars to enter and exit the container, which limits the vehicle type and the ramp's carrying capacity is small.

[0003] Especially for door ends equipped with locking rods and lock seats, the use of the ramp needs to avoid the lock seat on the threshold and the locking rod on the rotating door panel. Workers are generally forced to adjust the position and number of locking rods, or frequently move the ramp when opening and closing the door.

[0004] In summary, the existing ramps are limited in their usage scenarios and have poor applicability to the lock rod distribution of conventional standard containers. However, no relevant solutions to the problem have been found in the review of existing patents. Utility Model Content

[0005] The purpose of the utility model is to provide a door end ramp suitable for a container locking rod door, so as to improve the applicability of the slope to the locking rod door.

[0006] To achieve the above object, the present invention provides the following technical solution: a door end ramp suitable for a container lock rod door, wherein the container comprises a door panel equipped with a lock rod and a threshold equipped with a lock seat, and the door end ramp is placed below the door panel along the threshold.

[0007] The door end ramp includes a ramp body and a ramp panel. The ramp body is provided with a plurality of guide grooves, each of which corresponds to a set of the lock rods and the lock seats. The shape of the guide grooves follows the movement trajectory of the corresponding lock rods when the door is opened or closed.

[0008] The slope panel is arranged on the upper surface of the slope body and is a flippable structure. The slope panel can be flipped out of the guide groove. At this time, the door panel is moved and the lower end of the locking rod can pass through the guide groove.

[0009] Preferably, the slope panel includes a flip plate and a fixed plate, the fixed plate is fixed to the slope body, and the flip plate is hingedly connected to the fixed plate or the slope body; when the flip plate is not flipped, the guide groove is located below the flip plate.

[0010] Preferably, one side of the flip plate is connected to the fixed plate via a hinge, and a handle is provided on the upper surface of the opposite side, and the handle is respectively close to both sides of the door end ramp.

[0011] Preferably, a plurality of locking rod notches are provided on one side of the slope panel. When the door is in a closed state and the slope panel is not flipped over, each locking rod is placed in a corresponding locking rod notch.

[0012] Preferably, the slope panel is a patterned plate made of aluminum or carbon steel.

[0013] Preferably, a plurality of guide plates are provided inside the ramp body, with every two guide plates forming a group, and a guide groove is formed between each group of guide plates.

[0014] Preferably, equidistant longitudinal reinforcing plates are provided inside the ramp body, and the longitudinal reinforcing plates avoid the guide plates.

[0015] Preferably, the bottom of the slope body is provided with equidistant transverse reinforcement plates.

[0016] Preferably, the transverse reinforcement plate is a rectangular tube or a channel steel profile.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The present invention combines the movement trajectory of the lock rod when opening and closing the door with the design of a reversible slope panel and a guide groove inside the slope, which perfectly avoids the mutual influence between the lock rod and the ramp when opening and closing the door. Compared with the existing technology that requires moving the heavier ramp as a whole, the present invention only requires flipping the lightweight slope panel, saving time and effort.

[0019] 2. Compared with the existing technology, the utility model maximizes the width of the door-end ramp, which is suitable for larger vehicles to enter the box to pick up and unload goods, thereby increasing the one-time delivery volume of vehicles in and out of the box, improving the efficiency of loading and unloading goods in and out, reducing cold air loss, and saving energy consumption.

DETAILED DESCRIPTION

[0027] See also Figures 1 to 5 , the embodiment of the utility model discloses a door end ramp suitable for a container locking rod door.

[0028] like Figure 1 and Figure 2 As shown, the container 400 includes a door panel and a threshold 300. The door panels are bi-directional doors, each of which is equipped with two locking rods 200 at different positions. At the same time, the threshold 300 is equipped with a lock seat 201 corresponding to each locking rod 200. When the door panels are closed, the lower ends of the locking rods 200 engage with the lock seats 201 to achieve locking.

[0029] The door ramp is positioned below the door panel along the threshold 300. It comprises a ramp body 100 and a ramp panel 150. The ramp panel 150 is flipped and connected to the upper surface of the ramp body 100. The ramp body 100 is flanked by side beams 110, with the ramp panel 150 positioned between the two side beams 110. The side beams 110 can be rectangular tubes or channel steel. The ramp panel 150 can be constructed of patterned plate, aluminum, or carbon steel.

[0030] A space is formed between the ramp body 100 and the ramp panel 150. The ramp panel 150 can be flipped to reveal the space. Within this space, multiple guide plates 130 are welded to the ramp body 100. Each group of two guide plates 130 forms a guide groove between each group of guide plates 130. Each guide groove corresponds to a lock rod 200 and a lock seat 201. The shape of the guide groove follows the movement trajectory 500 of the lock rod 200 during door opening and closing. Due to the tilted position of the ramp body 100, the height of the guide plates 130, i.e., the depth of the guide groove, gradually decreases from the door end toward the outside. When the guide groove is exposed, the lower end of the lock rod 200 can pass through it, preventing interference between the lock rod 200 and the door ramp, allowing the door to be opened and closed at any time.

[0031] The motion trajectory 500 of the locking rod 200 is shown in FIG. Figure 2: The door panel is connected to the box body of the container 400 through a hinge. When the door is opened or closed, the door panel rotates around the hinge axis. The two locking rods 200 on the same door panel follow the door panel and move synchronously at different radii around the hinge axis of the door panel. The moving route is the motion trajectory 500 of the locking rod 200.

[0032] Since the movement track 500 of the locking rod 200 only occupies a small space on the horizontal plane, that is, the guide groove only occupies a small space, it is not necessary to design the slope panel 150 to be completely flipped. Figure 3 The ramp panel 150 includes a flip plate 151 and a fixed plate 152. The fixed plate 152 is welded between the ramp body 100 and its side beam 110. One side of the flip plate 151 is connected to the fixed plate 152 by a hinge 153. A handle 154 is provided on the upper surface of the opposite side. The handles 154 are respectively close to both sides of the door end ramp. Figure 3 and Figure 4 When the slope panel 150 is not flipped, the bottom of the flip plate 151 is a guide groove, covering the setting space, and the slope panel 150 as a whole serves as an uphill channel for loading vehicles to pass through.

[0033] When the slope panel 150 is not flipped, a side of the slope panel 150 close to the door sill 300 may further be provided with a plurality of locking rod notches 155, that is, a side of the flip plate 151 away from the hinge 153 has a plurality of locking rod notches 155, which can be referred to in Figure 4 To simplify the drawings and facilitate illustration, the locking rod notches 155 are omitted from the remaining drawings. The locking rod notches 155 are located just above the end of the guide groove near the threshold 300. When the container 400 is closed, each locking rod 200 is placed in a corresponding locking rod notch 155, and each lock seat 201 is located at the end of the guide groove near the threshold 300.

[0034] In order to enhance the strength of the door end ramp, equidistant longitudinal reinforcement plates 120 are welded in the space, and the longitudinal reinforcement plates 120 avoid the guide plates 130. At the same time, equidistant transverse reinforcement plates 140 are welded at the bottom of the ramp body 100. Figure 1 and Figure 5 The transverse reinforcement plate 140 can be made of a rectangular tube or a channel steel profile.

[0035] The operating principle of this utility model is as follows: Under normal circumstances, the door panel is closed, and the locking rod 200 is located in the locking rod notch 155 of the ramp panel 150. To open or close the door panel, the flip plate 151 on the surface of the ramp body 100 is flipped, revealing the guide groove in the space provided, allowing the locking rod 200 to pass through the door ramp unimpeded. After the door opening and closing operation is completed, the flip plate 151 is restored, and the trolley is then pushed onto the door ramp to carry out normal loading and unloading operations.

[0036] In summary, the present invention perfectly avoids the mutual influence between the lock rod 200 and the ramp when opening and closing the door by providing a guide groove in the door end ramp and a flip ramp panel 150 on the surface of the door end ramp. Compared with the prior art that requires moving the heavier ramp as a whole, the present invention only requires flipping the lightweight ramp panel 150, which saves time and effort. At the same time, because the placement of the door end ramp is no longer affected by the lock seat 201 and the lower end of the lock rod 200, the width of the door end ramp is maximized, and the distance between the side beams 110 of the door end ramp can be increased to the wide side length of the container 400, which is suitable for larger vehicles to enter the box to pick up and unload goods, thereby increasing the one-time delivery volume of vehicles in and out of the box, improving the efficiency of loading and unloading goods in and out, reducing cold air loss, and saving energy consumption.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
