Description

Technical Field

[0001] This utility model relates to the field of container technology, and more specifically to a sliding top container. Background Technology

[0002] In the field of container shipping, tarpaulin-covered open-top containers are widely used for transporting special cargo such as bulk cargo and granular cargo due to their unique loading and unloading advantages.

[0003] Existing open-top tarpaulin containers have a movable covering assembly covering the top opening. When the covering assembly is closed, the tarpaulin completely covers the opening; when the covering assembly is open, it moves towards the rear of the container, partially or completely exposing the opening. The covering assembly uses a drive mechanism to move a slider along a top side beam to open and close the opening. The drive mechanism is sprocket-driven, with the chain located on the outside of the container for easy manual operation.

[0004] However, the current chains cannot be secured to the sides of the container, causing them to swing and collide during transportation, and easily leading to the accidental opening of the shielding components, posing a safety risk.

[0005] Therefore, a sliding top container is needed to at least partially solve the above problems. Utility Model Content

[0006] The utility model description section introduces a series of simplified concepts, which will be further explained in detail in the detailed description section. This utility model description section is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0007] To at least partially solve the above problems, this utility model provides a sliding top container, the sliding top container comprising:

[0008] A box having a front end and a rear end, and an open top;

[0009] A shielding assembly, which is movably disposed on the top of the housing;

[0010] A drive chain, which is kinetically connected to the shielding assembly, is configured to switch the shielding assembly between a retracted state (opening the opening) and an extended state (covering the opening) in response to personnel operation; and

[0011] Limiting component, the limiting component includes:

[0012] A limiting bracket is disposed in the housing and has a channel that allows the drive chain to enter.

[0013] A limiting device is pivotally mounted on the limiting bracket. The limiting device can pivotally switch between a locked position and an open position. When the limiting device is in the open position, the drive chain can disengage from the channel or move in the channel. When the limiting device is in the locked position, the limiting device prevents the drive chain from disengaging from the channel and prevents the drive chain from moving in the channel.

[0014] According to the sliding top container of this application, by setting a limiting component on the outside of the container body, the driving chain is locked by the limiting component to prevent the sprocket from rotating due to its up-and-down swaying. This prevents the covering component from opening (extended state) or closing (retracted state) on its own. Furthermore, when the covering component is fully closed, the driving chain can be engaged with the limiting component, reducing the risk of the covering component accidentally opening during container transportation.

[0015] Optionally, the limiting bracket includes a first bracket and a second bracket, both of which are connected to the housing. The first bracket and the second bracket have portions that protrude toward each other to form the channel between the first bracket and the second bracket.

[0022] The second limiting pin is disposed on the second bracket, and the second limiting pin is further away from the first bracket relative to the second bracket;

[0023] The limiting device is pivotally connected to the first limiting pin. When the limiting device is in the open position, it is disengaged from the second limiting pin. When the limiting device is in the locked position, it is connected to the second limiting pin.

[0024] Optionally, the limiting device includes:

[0025] A pivoting portion, which is pivotally disposed on the first limiting pin;

[0026] A shielding portion, which is connected to the pivot portion;

[0027] An operating unit is connected to the shielding unit;

[0028] Wherein, the width of the blocking part is smaller than the width of the pivot part and the operating part, so as to form a groove between the pivot part and the operating part. When the limiting device is in the locked position, the second limiting pin is located in the groove and the blocking part overlaps with the second limiting pin.

[0029] Optionally, the center of gravity of the limiting device is located at the operating part, so that when the limiting device is in the open position, the operating part abuts against the box wall of the box body.

[0030] Optionally, the drive chain includes multiple links, and the minimum width of the channel is less than the width of the link and greater than the thickness of the link.

The traction component is connected to the shielding assembly, and the movement of the traction component can drive the shielding assembly to move. The transmission assembly is connected between the traction component and the drive chain. The transmission assembly includes a drive shaft that extends along the width direction of the sliding top container. The drive shaft is mounted on the top side beam via a bearing assembly. The drive shaft is provided with a pulley and a sprocket. The traction component is wound around the pulley, and the drive chain is wound around the sprocket.

[0032] A support assembly is also connected between the drive shaft and the top side beam.

[0033] Optionally, the support component includes:

[0034] A support base having a through hole, through which the drive shaft passes;

[0035] A first support plate is connected to the lower part of the support base;

[0090] Now, refer to Figures 1 to 14 Exemplary embodiments according to the present invention will be described in more detail below.

[0091] refer to Figure 1 , Figure 2 and Figure 3 This application provides a sliding top container 100, which includes a container body 101 with an opening 109 at the top. The container body 101 has a rear end 102 and a front end 103, which are the two ends of the container body 101 along the length direction D1, respectively. The rear end 102 is provided with an upward-opening door 112, so the rear end 102 can also be referred to as the door end. The upward-opening door 112 can be opened or closed relative to the sill beam 106. When the upward-opening door 112 is open, the rear end 102 forms a discharge port. The front end 103 is provided with a front wall panel with ventilation openings. When unloading is required, the upward-opening door 112 of the rear end 102 opens and tilts, and the material inside the container body 101 can be unloaded through the discharge port. For example, the rear end 102 can be tilted forward by raising the front end 103, and the front end 103 will also tilt forward after being raised. The ventilation openings can be constructed as multiple ventilation holes formed in the front wall panel. Alternatively, the vent can be configured as a single opening in the front wall panel.

[0092] The top of the housing 101 has a top beam 104 and a top side beam 105. Two top beams 104 are located at the rear end 102 and the front end 103, respectively, and two top side beams 105 are spaced apart and connected between the two top beams 104. Thus, the two top beams 104 and the two top side beams 105 form the aforementioned opening 109. The bottom of the housing 101 has a sill beam 106, a bottom beam, and a bottom side beam 107, where the sill beam 106 is located at the rear end 102 and the bottom beam is located at the front end 103. The bottom side beam 107 connects the sill beam 106 and the bottom side beam 107.

[0093] The sliding top container 100 also includes a shielding assembly 113, which is disposed on the top of the container body 101 and is switchable between an extended and retracted state. The shielding assembly 113 has a free end 115 that is movable relative to the end of the container body 101. In the retracted state, the free end 115 is spaced apart from the end of the container body 101 to open an opening 109. In the extended state, the free end 115 is located at the end of the container body 101 to shield the opening 109.

[0094] In one alternative embodiment, the shielding assembly 113 further has a fixed end 114 and a free end 115 that is movable relative to the fixed end 114 along the length direction D1 of the container 100. The fixed end 114 is located at the front end 103 of the container body 101. In the retracted state, the free end 115 is close to the front end 103 to open the opening 109. In the extended state, the free end 115 is located at the rear end 102 to shield the opening 109.

[0095] In an embodiment not shown, such as a 40-foot container, the shielding assembly may not have a fixed end; instead, both ends may be constructed as free ends, allowing the two ends of the shielding assembly to move towards the front and rear ends, respectively. In this embodiment, a fixed end may also be provided, but it is generally fixedly connected to the middle of the container body.

[0096] Alternatively, the free end of the shielding assembly can also be designed to move along the width direction D2 of the container; in other words, the shielding assembly can be constructed as a side-sliding structure.

[0097] The shielding assembly 113 includes multiple top arches 116, a tarpaulin assembly 117, and movable parts 124. The multiple top arches 116 are movably disposed on the top of the container 101 along the length direction D1, for example, on the top side beam 105. The movable parts 124 are disposed at both ends of the top arches 116 along the width direction D2 of the container 100. Preferably, the movable parts 124 may be disposed only on the top arches 116 forming the free ends 115. The top side beam 105 is provided with a guide structure, for example... Figure 4 and Figure 13As shown, the two top side beams 105 are constructed in an L-shape with their openings spaced far apart. The movable part 124 is connected to the guide structure so that the movable part 124 can move along the guide structure. The movable part 124 and the L-shaped top side beams 105 guide structure form a similar interlocking structure.

[0098] A tarpaulin assembly 117 covers the top arches 116. More specifically, one end of the tarpaulin assembly 117 is fixedly connected to the front end 103 of the housing 101 to form the fixed end 114 described above. The remainder of the tarpaulin assembly 117 covers a plurality of top arches 116, thereby allowing the top arches 116 to move to cover the opening 109. The top arch 116 furthest from the fixed end 114 forms the free end 115 described above.

[0099] refer to Figure 3 and Figure 4 The sliding top container 100 also includes a traction member 135, a transmission assembly 136, and a drive chain 141. The traction member 135 is connected to a plurality of top arches 116, and movement of the traction member 135 can drive the top arches 116 to move. The traction member 135 can be constructed, for example, as a wire rope. The transmission assembly 136 is connected to the traction member 135 and includes a drive shaft 137 extending along the width direction D2 of the sliding top container 100. The drive shaft 137 is mounted on the top side beam 105 via a bearing assembly 138. A pulley 139 and a sprocket 140 are mounted on the drive shaft 137, and the traction member 135 is wound around the pulley 139.

[0100] The drive chain 141 is connected to the transmission assembly 136. The drive chain 141 includes multiple interlocking chain links 141A wound around a sprocket 140. Its configuration is such that it moves the traction member 135 in response to personnel operation. Specifically, when a person pulls the drive chain 141, the drive chain 141 drives the sprocket 140 to rotate, the sprocket 140 drives the transmission shaft 137 to rotate, which in turn drives the pulley 139 to rotate, thereby tightening or releasing the traction member 135.

[0101] As one implementation, refer to Figure 1 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 The sliding top container 100 also includes a limiting assembly 147, which is disposed on the container body 101 and is used to limit the position of the drive chain 141 when no personnel are operating it. The limiting assembly 147 includes a limiting bracket 148 and a limiting device 157.

[0102] A limiting bracket 148 is disposed on the housing 101, forming a channel 154 that allows the drive chain 141 to enter. A limiting device 157 is pivotally disposed on the limiting bracket 148 and is pivotally switchable between a locked position and an open position. When the limiting device 157 is in the open position, the drive chain 141 can disengage from the channel 154 or move within the channel 154. When the limiting device 157 is in the locked position, the limiting device 157 prevents the drive chain 141 from disengaging from the channel 154 and prevents the drive chain 141 from moving within the channel 154.

[0103] According to the sliding top container 100 of this application, by providing a limiting component 147 on the outside of the container body 101, the driving chain 141 is locked by the limiting component 147 to prevent the sprocket 140 from rotating due to its up-and-down swaying. This prevents the shielding component 113 from opening (extended state) or closing (retracted state) on its own. Furthermore, when the shielding component 113 is fully closed, the driving chain 141 can be engaged with the limiting component 147, reducing the risk of the shielding component 113 accidentally opening during the transportation of the container 100.

[0104] refer to Figure 7 and Figure 8 The limiting bracket 148 includes a first bracket and a second bracket, both of which are connected to the housing 101. The first and second brackets have protruding portions facing each other to form the aforementioned channel between them. The first bracket includes a first bracket portion 150 and a first bracket plate 149A. The second bracket includes a second bracket portion 152 and a second bracket plate 149B. Both the first bracket portion 150 and the second bracket portion 152 are located near the front end 103 of the housing 101. The first bracket portion 150 is connected to the side wall of the housing 101 and the column 146 of the front end 103, while the second bracket portion 152 is connected to the column of the front end 103. It can be understood that the second bracket portion 152 is further away from the side wall of the housing 101 than the first bracket portion 150. The first bracket plate 149A is located at the end of the first bracket portion 150 away from the column 146, and the second bracket plate 149B is located at the end of the second bracket portion 152 away from the column 146. The limiting device 157 is pivotally mounted on the first support plate 149A.

[0105] The first support portion 150 and the second support portion 152 have portions that protrude toward each other, thereby forming a channel 154 between the first support portion 150 and the second support portion 152. Specifically, the first support portion 150 has a first bend 151, and the second support portion 152 has a second bend 153. The first bend 151 and the second bend 153 are oriented toward each other, thereby forming the aforementioned channel 154 between the first bend 151 and the second bend 153.

[0106] The width of the aforementioned channel 154, or the minimum distance between the first support portion 150 and the second support portion 152, is less than the width of the link 141A of the driving chain 141 but greater than the thickness of the link 141A. Therefore, when a link 141A is engaged in the channel 154 of the limiting bracket 148, the driving chain 141 cannot move up or down because adjacent links 141A are in opposite directions, thus achieving height-direction limiting. When the limiting device 157 is in the locked position, it prevents the driving chain 141 from disengaging from the aforementioned channel 154.

[0107] The limiting assembly 147 further includes a first limiting pin 155 and a second limiting pin 156. The first limiting pin 155 is disposed on the first support plate 149A, and the first limiting pin 155 is further away from the second support portion 152 relative to the first support portion 150. Preferably, the first limiting pin 155 is disposed on the side of the first bent portion 151 near the side wall of the housing 101. The second limiting pin 156 is disposed on the second support plate 149B, and the second limiting pin 156 is further away from the first support portion 150 relative to the second support portion 152. Preferably, the second limiting pin 156 is disposed on the side of the second bent portion 153 away from the side wall of the housing 101.

[0108] The limiting device 157 is pivotally connected to the first limiting pin 155. When the limiting device 157 is in the open position, such as Figure 7 As shown, the limiting device 157 disengages from the second limiting pin 156. When the limiting device 157 is in the locked position, as... Figure 8 As shown, the limiting device 157 is connected to the second limiting pin 156, and the second limiting pin 156 prevents the limiting device 157 from continuing to rotate downward.

[0109] refer to Figure 9 The limiting device 157 includes a pivoting part 158, a blocking part 159, and an operating part 160. The pivoting part 158 ​​is pivotally disposed on the first limiting pin 155, the blocking part 159 is connected to the pivoting part 158, and the operating part 160 is connected to the blocking part 159. In other words, the blocking part 159 is disposed between the pivoting part 158 ​​and the operating part 160.

[0110] The width of the blocking portion 159 is smaller than the width of the pivot portion 158 and the operating portion 160, forming a groove between the pivot portion 158 and the operating portion 160. When the limiting device 157 is in the locked position, the second limiting pin 156 is located in the groove and the blocking portion 159 engages with the second limiting pin 156. In other words, when the limiting device 157 is in the locked position, the limiting device 157 is engaged with the second limiting pin 156.

[0111] Preferably, the center of gravity of the limiting device 157 is located at the operating part 160, so that when the limiting device 157 is in the open position, the container wall prevents the limiting device 157 from continuing to rotate inward, and the operating part 160 abuts against the container wall of the container body 101, thus eliminating the need for manual maintenance of the open position. Furthermore, this design allows the operating part 160 to automatically fall down after being manually moved, thereby entering the locked position. For example, when the angle between the center of gravity of the limiting device 157 and the axis of rotation is no greater than 90 degrees, the limiting device 157 can automatically close by gravity, avoiding the risk of accidental opening during container 100 transportation.

[0112] refer to Figure 4 A support assembly 142 is also connected between the drive shaft 137 and the top side beam 105. The support assembly 142 includes a support 143, a first support plate 144, and a second support plate 145. A through hole is provided on the support 143, through which the drive shaft 137 passes. The first support plate 144 is connected to the lower part of the support 143, and the second support plate 145 is connected to the top side beam 105 and abuts against the first support plate 144. Furthermore, the second support plate 145 is connected to the first support plate 144 by fasteners. Through the aforementioned support assembly 142, the support strength of the drive shaft 137 can be enhanced, the load-bearing capacity of the bearing assembly 138 can be distributed, and the service life of the entire shielding assembly 113 can be guaranteed.

[0113] refer to Figure 1 and Figure 10 The sliding top container 100 also includes a drainage assembly 125, which comprises a drainage structure and a sealing portion 128. The drainage structure is connected to the container body 101 and includes a drainage portion 126 and a water-blocking portion 127. The drainage portion 126 is connected to the rear end 102 of the container body 101 and extends into the interior of the container body 101, preferably extending obliquely upwards. The water-blocking portion 127 is connected to the drainage portion 126 and extends vertically along D3 or obliquely upwards. The sealing portion 128 is connected to the drainage structure, specifically to the side of the water-blocking portion 127 facing the rear end 102. In the retracted state, the top of the drainage assembly 125 is open.

[0114] The sealing portion 128 specifically includes a first vertical plate 129, a second vertical plate 130, and the aforementioned horizontal plate 131. The first vertical plate 129 is connected to the water-blocking portion 127, the second vertical plate 130 is spaced apart from the first vertical plate 129, and the horizontal plate 131 connects the top ends of the first vertical plate 129 and the second vertical plate 130, so that the sealing portion 128 forms a downward-facing opening. Thus, the sealing portion 128 generally forms a downward-facing U-shape. The first vertical plate can be integrally constructed with the water-blocking portion 127, or alternatively, the first vertical plate can be omitted, and the horizontal plate 131 can be directly connected to the water-blocking portion 127.

[0115] like Figure 12As shown, the top arch 116 is higher than the sides at the middle of the width direction D2 of the container 100 to form a first curved profile, and the drain assembly 125 is higher than the sides at the middle of the width direction D2 of the container 100 to form a second curved profile, wherein the shape of the first curved profile is adapted to the shape of the second curved profile.

[0116] refer to Figure 13 The drainage assembly 125 also includes an end sealing plate 132, which is disposed at the end of the sealing portion 128 along the width direction D2 and connected to the drainage portion 126 and / or the water-blocking portion 127 to prevent water from entering from the side. In addition, the end sealing plate 132 can also prevent water falling on the drainage portion 126 from splashing into the tank.

[0117] refer to Figure 14 In the extended state, the projection of the end sealing plate 132 onto a vertical plane perpendicular to the width direction D2 at least partially overlaps with the projection of the moving part 124 onto a vertical plane perpendicular to the width direction D2. In other words, they partially obscure each other in the width direction. A small gap exists between the outer surface of the end sealing plate 132 along the width direction D2 and the moving part 124, for example, the gap is less than 10 mm, thereby achieving a certain sealing effect. As a preferred embodiment, a sealing element 133 is provided on the outer surface of the end sealing plate 132 along the width direction D2, thereby sealing the gap between the moving part 124 and the end sealing plate 132, further improving waterproofing. The sealing element 133 can be a flexible material such as a small tarpaulin or a rubber block. The drainage assembly 125 also includes a reinforcing part 134, located below the drainage part 126. One end of the reinforcing part 134 is connected to the housing 101, and the other end is connected to the drainage part 126.

[0118] The tarpaulin assembly 117 includes a surface portion 118, a first water-blocking curtain 119, and a second water-blocking curtain 120, with the surface portion 118 covering the top arch 116. The first water-blocking curtain 119 and the second water-blocking curtain 120 are connected to the surface portion 118. The first water-blocking curtain 119 is located at the free end 115, and the second water-blocking curtain 120 is located away from the free end 115 relative to the first water-blocking curtain 119. Alternatively, the second water-blocking curtain 120 is located between the free end 115 and the fixed end 114, and is positioned close to the free end 115. Furthermore, both the first water-blocking curtain 119 and the second water-blocking curtain 120 extend downwards. In other words, both the first water-blocking curtain 119 and the second water-blocking curtain 120 are drooping downwards.

[0119] In the extended state, the first water-blocking curtain 119 is located on the outer side of the sealing portion 128 relative to the middle of the housing 101. For example, the first water-blocking curtain 119 can be located between the sealing portion 128 and the rear end 102, and the second water-blocking curtain 120 abuts against the top surface of the sealing portion 128. Alternatively, in the extended state, the first water-blocking curtain 119 extends beyond the sealing portion 128. Preferably, the first water-blocking curtain 119 can partially or completely cover the drainage assembly 125 in the height direction, thereby achieving a waterproof sealing effect. In the extended state, the second water-blocking curtain 120 is connected to the middle of the upper surface of the horizontal plate 131. Alternatively, the second water-blocking curtain 120 is not tangential to the edge of the horizontal plate 131. This method has better sealing performance. In the case where the second water-blocking curtain 120 is tangentially in contact with the edge of the horizontal plate 131, there is a relatively higher probability of leakage.

[0120] In a preferred embodiment, the length of the second water curtain 120 should not be too long, as an excessively long length could cause the second water curtain 120 to be tangent to the edge of the horizontal plate 131. Specifically, the difference between the length of the second water curtain 120 and the distance between the tarpaulin portion 118 and the horizontal plate 131 is less than half the length of the horizontal plate 131 along the length of the container. The length of the second water curtain 120 is related to the stiffness of the tarpaulin; when the tarpaulin is softer, it can be slightly longer without easily losing contact with the middle of the upper surface of the horizontal plate 131.

[0121] refer to Figure 10 and Figure 11 The tarpaulin assembly 117 also includes a limiting sleeve 123 and a sealing sleeve 122. Both the limiting sleeve 123 and the sealing sleeve 122 are connected to the tarpaulin portion 118. The limiting sleeve 123 covers each top arch 116 except for the sealing sleeve 122, and the sealing sleeve 122 covers at least one top arch 116, for example, it needs to cover at least the top arch 116 forming the free end 115. Optionally, the sealing sleeve 122 includes at least two top arches 116 arranged sequentially from the free end 115 toward the fixed end 114. Both can be used to extend or retract the tarpaulin assembly 117 together when the top arches 116 move, thereby causing the tarpaulin assembly 117 to move back and forth in an overlapping manner, making the movement of the tarpaulin assembly 117 more stable. Furthermore, in the extended state, the sealing sleeve 122 is at least partially located above the sealing portion 128, and the sealing sleeve 122 abuts against the sealing portion 128 or the distance between the sealing sleeve 122 and the sealing portion 128 is less than 10 mm. Thus, based on the two labyrinth seals formed by the first water curtain 119 and the second water curtain 120, the sealing sleeve 122 additionally forms a third seal, further improving water tightness.

[0122] refer to Figure 12The tarpaulin assembly 117 also includes a third water curtain 121, which is located outside the movable portion 124 along the length direction D1 and extends downward, or in other words, the third water curtain 121 is also drooping downward. Furthermore, the third water curtain 121 can also be located outside the movable portion 124 along the width direction. In other words, the third water curtain 121 can be configured to surround the corner of the movable portion 124 or the top arch 116.

[0123] Preferably, the third water curtain 121 overlaps with the first water curtain 119 at the moving part 124, and the third water curtain 121 and the first water curtain 119 are fixed to the moving part 124 by fasteners. When the shielding assembly 113 is in the extended state, the drooping third water curtain 121 can prevent water from entering the gap between the moving part 124 and the end sealing plate 132 bracket, thus sealing both sides of the rear end 120 along the width direction D2. It is worth mentioning that, since there are guide structures on both sides of the housing 101, in order to avoid affecting the sliding of the moving part 124, the length of the third water curtain 121 is preferably less than the length of the first water curtain 119. Specifically, the vertical length of the third water curtain 121 is less than or equal to the maximum distance between the upper surface of the guide structure and the upper surface of the moving part 124. More specifically, the vertical length of the third water curtain 121 is less than or equal to the distance between the lower surface of the L-shaped structure formed by the top side beam 105 and the upper surface of the moving part 124.
