Description

Technical Field

[0001] The present application relates to the field of cargo transportation, and in particular to a skeleton-type semitrailer. Background Art

[0002] In the field of transportation, there is a device called a semi-trailer, which is a widely used vehicle for inland long-distance dry cargo transportation in Europe and the United States. The most commonly used semi-trailer is a skeleton semi-trailer for carrying containers.

[0003] A related skeleton-type semi-trailer hoists the container onto the vehicle body when transporting the container, so that the four corners of the container are connected to the vehicle body, and then the container and the vehicle body are fixed with locks.

[0004] During transportation, when encountering bumpy roads, the container will be bumped and shaken, reducing the stability of container transportation. Summary of the invention

[0005] In order to improve the stability of container transportation, the present application provides a skeleton-type semi-trailer.

[0006] The present application provides a skeleton-type semitrailer, which adopts the following technical solution: A skeleton type semi-trailer, comprising Frame; A reinforcement component, which is arranged at the upper end of the frame and is used to fix the container to the frame; A clamping assembly, the clamping assembly is connected to the reinforcement assembly and is used to clamp the container; The clamping assembly comprises: A matching portion, the matching portion being arranged on the frame; A clamping portion, the clamping portion being disposed at an upper end of the matching portion; A driving assembly is arranged at the upper end of the frame and is used to drive the reinforcement assembly and the clamping assembly to move.

[0007] By adopting the above technical solution, the container is hoisted on the frame. When the container is close to the frame, the gravity of the container itself pushes the driving component, and then the driving component drives the reinforcement component close to the bottom wall of the container. At the same time, it drives the clamping component close to the two sides of the container, thereby enhancing the stability of the container.

[0008] Optionally, a movable groove is transversely arranged on the horizontal portion of the frame, and sliding grooves are transversely arranged at both ends of the movable groove, and the driving assembly includes: A driving block, wherein two driving blocks are provided, and both of the two driving blocks are slidably disposed in the sliding groove; a first connecting rod, one end of which is hinged to one end of one of the driving blocks; a second connecting rod, one end of which is hinged to one end of the other driving block; a first spring, one end of which is fixedly connected to one end of one of the driving blocks, and the other end of which is fixedly connected to one end of the other driving block; A pressing plate, the lower end of which is hinged to the first connecting rod and the second connecting rod respectively; The first connecting rod and the second connecting rod are cross-arranged, and the intersection of the first connecting rod and the second connecting rod is rotatably connected via a rotating shaft.

[0009] By adopting the above technical solution, the existence of the driving block makes the slide slot closed. When the container approaches the pressure plate, the pressure plate drives the first connecting rod and the second connecting rod to push the driving block to slide, providing a buffer space for the container. At the same time, the driving block slides to drive the reinforcement assembly to connect with the container, which is simple and easy to operate.

[0010] Optionally, a matching groove is vertically provided at the upper end of the frame, the matching groove is communicated with the slide groove, and the reinforcement assembly includes: A push rod, two of which are provided, and both of the two push rods are slidably disposed in the matching groove; The reinforcement plates are provided with two, and one end of the two reinforcement plates is fixed to the end of the push rod away from the matching groove.

[0011] By adopting the above technical solution, the presence of the push rod and the reinforcement plate enables the reinforcement plate to be driven to connect with the container when the container is placed, thereby preliminarily strengthening the connection stability between the container and the frame.

[0012] Optionally, the matching portion includes: A connecting rod, wherein two connecting rods are provided, and the two connecting rods are respectively fixed at two ends of the horizontal part of the frame, and the two connecting rods are both connected to the slide groove; Trachea, wherein two trachea are provided, and the two trachea are respectively arranged in the two connecting rods; The clamping portion comprises: Coordinating rods, two of which are provided, one end of each of the two coordinating rods is fixed to the upper ends of the two connecting rods, wherein the two air pipes are connected to the two connecting rods; The clamping block is provided with two clamping blocks, and one end of the two clamping blocks is slidably arranged in the matching rod.

[0013] By adopting the above technical solution, the container is placed on the frame, and the driving block slides to squeeze the inert gas. The inert gas enters the matching rod through the air pipe, so that the gas in the matching rod pushes the clamping block to move toward the end close to the container, and at the same time stretches the second spring, thereby driving the clamping block to be fixed to the side end of the container by magnetic attraction, further increasing the connection stability of the container.

[0014] Optionally, the reinforcement assembly, the clamping assembly and the driving assembly are all arranged at intervals.

[0015] By adopting the above technical solution, the reinforcement components, the clamping components and the driving components are all arranged at intervals, which can increase the connection stability of the container, while reducing the load of a single component and increasing the service life.

[0016] Optionally, a magnet is provided at one end of the two clamping blocks that are close to each other, and a magnet is provided at one end of the two reinforcement plates that are away from the matching groove.

[0017] By adopting the above technical solution, the setting of the magnets makes the connection between the container and the frame stable, simple and convenient.

[0018] Optionally, the driving block is a rubber plug.

[0019] By adopting the above technical solution, the setting of the rubber plug enables the driving block to seal the slide groove during the pushing process, which is simple and easy to operate.

[0020] Optionally, an inert gas is provided in the horizontal portion of the frame and the air pipe. By adopting the above technical solution, the provision of inert gas ensures the safety of vehicle transportation during use.

[0021] In summary, the embodiment of the present invention provides a skeleton-type semi-trailer, which includes at least one of the following beneficial technical effects: 1. Hoist the container onto the frame. When the container is close to the frame, the gravity of the container pushes the driving assembly, and then the driving assembly drives the reinforcement assembly close to the bottom wall of the container. At the same time, it drives the clamping assembly close to both sides of the container, thereby enhancing the stability of the container.

[0022] 2. Place the container on the frame, and the driving block slides to squeeze the inert gas. The inert gas enters the matching rod through the air pipe, so that the gas in the matching rod pushes the clamping block to move toward the end close to the container, and at the same time stretches the second spring, thereby driving the clamping block to be fixed to the side end of the container by magnetic attraction, further increasing the connection stability of the container.

[0025] The following is combined with Figure 1-3 This application is described in further detail.

[0026] Combination Figure 1 , Figure 2 and Figure 3 The embodiment of the present application discloses a skeleton-type semi-trailer, comprising: a frame 1, a reinforcement assembly 3, the reinforcement assembly 3 is arranged at the upper end of the frame 1, and is used to fix a container to the frame 1; a clamping assembly 4, the clamping assembly 4 is connected to the reinforcement assembly 3, and is used to clamp the container; the clamping assembly 4 comprises: a matching part, the matching part is arranged on the frame 1; a clamping part, the clamping part is arranged at the upper end of the matching part; a driving assembly 2, the driving assembly 2 is arranged at the upper end of the frame 1, and is used to drive the reinforcement assembly 3 and the clamping assembly 4 to move.

[0027] In the embodiment of the present application, the frame 1 is welded by a cross beam, a longitudinal beam, and front and rear end beams. The length of the frame 1 is set according to specific use requirements, and this application does not make specific restrictions. In specific use, the container is hoisted on the frame 1. When the container is close to the frame 1, the gravity of the container itself pushes the driving component 2, and then the driving component 2 drives the reinforcement component 3 to approach the bottom wall of the container, and at the same time, drives the clamping component 4 to approach the two sides of the container, thereby enhancing the stability of the container.

[0028] Combination Figure 1 , Figure 2 and Figure 3In a specific embodiment, a movable groove 11 is horizontally provided on the horizontal part of the frame 1, and slide grooves 12 are horizontally provided at both ends of the movable groove 11. The driving assembly 2 includes: a driving block 21, a first connecting rod 22, a second connecting rod 23, a pressure plate 25, and a first spring 24. Two driving blocks 21 are provided, and both driving blocks 21 are slidably set in the slide groove 12; one end of the first connecting rod 22 is hinged to one end of one of the driving blocks 21; one end of the second connecting rod 23 is hinged to one end of the other driving block 21; the lower end of the pressure plate 25 is hinged to the first connecting rod 22 and the second connecting rod 23 respectively; one end of the first spring 24 is fixedly connected to one end of one of the driving blocks 21, and the other end of the first spring 24 is fixedly connected to one end of the other driving block 21, wherein the first connecting rod 22 and the second connecting rod 23 are cross-arranged, and the intersection of the first connecting rod 22 and the second connecting rod 23 is rotatably connected through a rotating shaft.

[0029] In the embodiment of the present application, the movable groove 11 is U-shaped, the slide groove 12 is cylindrical, and the driving block 21 is cylindrical. It should be noted that one end of the driving block 21 arranged in the slide groove 12 is provided with a guide slope, and the first connecting rod 22 and the second connecting rod 23 are both rectangular. It should be noted that the specifications of the first connecting rod 22 and the second connecting rod 23 are consistent, and the pressure plate 25 is square. The slide groove 12 is filled with inert gas, and the driving block 21 is a rubber plug. In specific use, when the container is placed on the frame 1, the lower end of the container first conflicts with the upper end of the pressure plate 25, and then due to the dead weight of the container, the pressure plate 25 continues to be pressed. The pressure plate 25 is pressed downward to increase the angle of the upper ends of the first connecting rod 22 and the second connecting rod 23. At the same time, the pressure plate 25 drives the two driving blocks 21 to slide toward the ends away from each other during the downward movement, and the first spring 24 is stretched. Since the driving block 21 is a rubber plug, the inert gas in the slide groove 12 is squeezed during the sliding process, and the slide groove 12 is sealed at the same time so that the inert gas does not overflow. When the container is taken away, due to the elastic recovery potential energy of the first spring 24, the first spring 24 contracts, and the two driving blocks 21 are pulled toward the ends close to each other, thereby restoring the pressure plate 25 to its original state. The operation is simple and convenient.

[0030] Combination Figure 1 , Figure 2 and Figure 3 In a specific embodiment, a matching groove 31 is vertically provided at the upper end of the frame 1, and the matching groove 31 is connected to the slide groove 12. The reinforcement component 3 includes: a pushing rod 32 and a reinforcement plate 33. Two pushing rods 32 are provided, and both pushing rods 32 are slidably provided in the matching groove 31; two reinforcement plates 33 are provided, and one end of the two reinforcement plates 33 is fixed to the end of the pushing rod 32 away from the matching groove 31.

[0031] In the embodiment of the present application, the mating groove 31 is square and the pushing rod 32 is rectangular. It should be noted that the specifications of the pushing rod 32 are sufficient to slide in the mating groove 31. The end of the pushing rod 32 placed in the slide groove 12 is provided with a guide slope. The reinforcement plate 33 is square. The bottom end of the reinforcement plate 33 and the end of the pushing rod 32 away from the mating groove 31 can be integrally formed or fixedly connected by bonding or bolting. The reinforcement plate 33 is a magnet, and the magnetic force is specifically set according to the specific usage conditions, so that the container is not easy to shake under the action of the magnetic force. In actual use, when the container is placed on the frame 1, the container pushes the pressure plate 25 toward the end close to the frame 1, and then the two drive blocks 21 slide toward the ends away from each other. Since the drive block 21 and the push rod 32 are both provided with guide slopes, when the drive block 21 slides in the slide groove 12, the drive block 21 pushes the rod 32 to move toward the end close to the container. Since the reinforcement plate 33 is provided with a magnet and the container is generally made of metal, when the reinforcement plate 33 contacts the bottom wall of the container, the two reinforcement plates 33 fix the container due to the magnetic force, thereby preliminarily increasing the fixing stability of the container and the frame 1.

[0032] Combination Figure 1 , Figure 2 and Figure 3 In a specific embodiment, the clamping assembly 4 includes a matching portion and a clamping portion, the matching portion includes a connecting rod 42, an air pipe 43, the clamping portion includes a matching rod 44, and a clamping block 41, two connecting rods 42 are provided, the two connecting rods 42 are respectively fixed at the two ends of the horizontal portion of the frame 1, and the two connecting rods 42 are both connected to the slide groove 12; two air pipes 43 are provided, the two air pipes 43 are respectively arranged in the two connecting rods 42; two matching rods 44 are provided, one end of the two matching rods 44 are fixed at the upper ends of the two connecting rods 42, wherein the two air pipes 43 are both connected to the two connecting rods 42; two clamping blocks 41 are provided, one end of the two clamping blocks 41 are slidably arranged in the matching rod 44.

[0033] In the embodiment of the present application, the connecting rod 42 is arranged in a rectangular shape, the air pipe 43 can be a plastic hose or a steel pipe, the matching rod 44 is arranged in a rectangular hollow shape, wherein a second spring is fixedly arranged on the bottom wall of the matching rod 44, the other end of the second spring is fixedly connected to one end of the clamping block 41 placed in the matching rod 44, the clamping block 41 is arranged in a T shape, and a magnet is arranged at one end of the clamping block 41 away from the matching rod 44. It should be noted that the length of the matching rod 44 is sufficient for the clamping block 41 to clamp the side end of the container when the container is placed on the frame 1, and the length of the air pipe 43 is sufficient for connecting the matching rod 44 and the slide groove 12.

[0034] In actual use, the container is placed on the frame 1, and the drive block 21 slides to squeeze the inert gas. The inert gas enters the matching rod 44 through the air pipe 43, so that the gas in the matching rod 44 pushes the clamping block 41 to move toward one end close to the container, and at the same time stretches the second spring, thereby driving the clamping block 41 to be fixed to the side end of the container by magnetic attraction, further increasing the connection stability of the container. The reinforcement components 3 are arranged at intervals along the length direction of the frame 1, and the clamping components 4 and the drive components 2 are arranged one-to-one with the reinforcement components 3, that is, the reinforcement components 3, the clamping components 4 and the drive components 2 are arranged at intervals in multiple groups, which can increase the connection stability of the container, while reducing the load of a single component and increasing the service life.

[0035] The implementation principle of the embodiment of the present application is as follows: when the container is placed on the frame 1, first, the lower end of the container contacts the upper end of the pressure plate 25, and then due to the deadweight of the container, the pressure plate 25 continues to be pressed downward, so that the angles of the upper ends of the first connecting rod 22 and the second connecting rod 23 become larger. At the same time, the pressure plate 25 drives the two driving blocks 21 to slide toward the ends away from each other during the downward movement, stretching the first spring 24. The driving block 21 squeezes the inert gas in the slide groove 12 during the sliding process, and at the same time, the driving block 21 pushes the rod 32 to move toward the end close to the container. The two reinforcement plates 33 fix the container due to the magnetic force, thereby preliminarily increasing the fixing stability of the container and the frame 1. The inert gas enters the matching rod 44 through the air pipe 43, so that the gas in the matching rod 44 pushes the clamping block 41 to move toward the end close to the container, and at the same time stretches the second spring, thereby driving the clamping block 41 to be fixed to the side end of the container by magnetic attraction, further increasing the connection stability of the container.
