Description

Technical Field

[0001] The utility model belongs to the technical field of semi-trailers, and particularly relates to a self-unloading semi-trailer with multiple carriages and multiple unloading methods. Background Art

[0002] A semi-trailer is a trailer with axles placed behind the center of gravity of the vehicle and equipped with a coupling device that can transfer horizontal and vertical forces to the tractor. Generally, a semi-trailer is a three-axle semi-trailer, and its types include various types such as an 11-meter barn semi-trailer, a 13-meter barn, and a low-bed semi-trailer. It is a heavy transportation vehicle connected to the semi-trailer head through a kingpin.

[0003] Currently, when most semi-trailers use the carriage for cargo transportation, the carriage needs to be lifted and tilted during unloading. Since the carriage of a semi-trailer is generally set as a whole, the center of gravity of the semi-trailer rises significantly after the carriage is lifted, thus affecting the safety and stability of the semi-trailer and easily causing rollover due to the too high center of gravity. At the same time, due to the long length and large size of the carriage, it is difficult to manufacture, and when lifting, higher requirements for lifting are needed, increasing the use cost. Also, during unloading, if all unloading is done through the side, it is easy for the vehicle tires to sink into the soft ground, resulting in the vehicle being unable to move forward and leave the cargo yard. And if all unloading is done through rear tilting, it is easy because of too much cargo, and the vehicle needs to be towed forward multiple times to finish unloading the cargo, making the unloading inconvenient and affecting people's use. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a self-unloading semi-trailer with multiple carriages and multiple unloading methods, aiming to solve the problems raised in the above background art.

Specific embodiments

[0023] In order to make the above objects, features and advantages of the present utility model more obvious and understandable, the following will describe the specific embodiments of the present utility model in detail with reference to the accompanying drawings of the specification.

[0024] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0025] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation manner of the present utility model. The "in one embodiment" appearing in different places in this specification does not all refer to the same embodiment, nor is it a separate or alternative embodiment that excludes other embodiments.

[0026] Embodiment 1

[0027] Referring to Figures 1 - 5 , this is the first embodiment of the present utility model. This embodiment provides a self-unloading semi-trailer with multiple carriages and multiple unloading methods, including,

[0028] A vehicle frame assembly 100, including a main vehicle frame 101 and a sub-frame 102 installed at the tail of the main vehicle frame 101. Support seats 103 of the same specification are rotatably installed at the upper ends of the main vehicle frame 101 and the sub-frame 102, and a carriage 104 is hinged in the middle of the support seats 103.

[0029] The support base 103 is rotatable on the upper ends of the main frame 101 and the auxiliary frame 102 to cooperate with the installation of the carriage 104. The support base 103 is rotated along the main axis of the upper ends of the main frame 101 and the auxiliary frame 102, and the direction of the carriage 104 can be rotated to adjust the direction of the carriage 104, which is convenient for unloading and unloading from any position near the main frame 101 and the auxiliary frame 102. The adjustment is convenient, and the carriage 104 installed on the upper ends of the main frame 101 and the auxiliary frame 102 can be unloaded separately, so that the carriages of the semi-trailer can be used separately and unloaded through their respective doors, thereby improving the safety and stability of the semi-trailer unloading. The center of gravity of the carriage 104 is lowered during unloading, avoiding the risk of overturning due to excessive center of gravity, reducing the requirements for the unloading site, and avoiding the tires being pressed into the soft ground by excessive weight of the cargo, so that the vehicle cannot move forward to leave the cargo yard. There is no need to tow the vehicle forward multiple times to unload the cargo, which is convenient for the operator to control the unloading.

[0030] Specifically, a positioning hole 105 matching the bottom of the vehicle box 104 is opened on one side of the upper end of the support base 103 , and a push rod 106 is inserted in the middle of the positioning hole 105 .

[0031] Among them, adding a top rod 106 to connect the support base 103 and the car body 104 can provide a certain supporting force to the car body 104 through the top rod 106 on the basis of the installation of the support base 103, so that the car body 104 can maintain a tilted state at a specific angle, which is convenient for tilted unloading, or maintaining the equipment placed in the car body to operate at a specific angle.

[0032] Furthermore, sleeves 107 are installed on the outer side walls of the main frame 101 and the auxiliary frame 102 , and a column 108 is movably inserted in the middle of the sleeve 107 , and a foot pad is installed at the bottom of the column 108 .

[0033] Among them, a sleeve 107 with a column 108 is installed on the side walls of the main frame 101 and the subframe 102, and the extension distance of the column 108 is adjusted along the sleeve 107 to change the connection state of the column 108 with the ground. Then, the column 108 is fixed in the middle of the sleeve 107 by a handle bolt or a latch rod or other components, which facilitates the support of the main frame 101 and the subframe 102, further maintains the stability of the position of the main frame 101 and the subframe 102 during unloading, and prevents the vehicle from rolling over.

[0034] Furthermore, support rods 109 of the same specifications are hinged at the middle position of the lower ends of the main frame 101 and the auxiliary frame 102, and a pin hole structure matching the side wall of the support rod 109 is opened on one side of the lower ends of the main frame 101 and the auxiliary frame 102.

[0035] Among them, a support rod 109 is added to separately support the main frame 101 and the sub-frame 102 when the main frame 101 or the sub-frame 102 is used alone, maintain the stability of the positions of the main frame 101 and the sub-frame 102, and adapt to different usage requirements.

[0036] Preferably, a fixing seat 110 is connected to the middle position of the main frame 101 by bolts, and a cushion block 111 is installed on the top of the fixing seat 110.

[0037] Among them, a fixing seat 110 with a cushion block 111 is installed in the middle of the main frame 101. The fixing seat 110 can store a certain amount of materials inside, or can install independent control equipment to adjust the unloading or lifting of the carriage. A guiding device can be installed above the fixing seat 110 as needed for unloading liquid or fluid materials, and it is also convenient to guide packaged items to improve the unloading efficiency.

[0038] It should be noted that a motor 112 is connected to the bottom of the main frame 101 by bolts, a main gear 113 is key-connected to the main shaft end of the motor 112, and the teeth on the side wall of the main gear 113 mesh with the rack inside the support seat 103.

[0039] Among them, a motor 112 with a main gear 113 is installed at the bottom of the main frame 101. By turning on the power of the motor 112 through the control equipment, the support seat 103 can be driven by the main gear 113 to rotate along the upper main shaft of the main frame 101, and the direction of the carriage 104 installed on the support seat 103 can be adjusted, which is convenient for discharging materials from different positions and is easy to adjust.

[0040] During use, rotate the support rod 109 so that the support rod 109 is perpendicular to the main frame 101, then fix the support rod 109, pull out the pin rod, place the upright columns 108 on the ground foundation in sequence, and then fix the upright columns 108 on the side wall of the sleeve 107 in sequence. By turning on the power of the motor 112 through the control equipment, the support seat 103 can be driven by the main gear 113 to rotate along the upper main shaft of the main frame 101, and the direction of the carriage 104 installed on the support seat 103 can be adjusted to cooperate with the unloading assembly 200 for unloading operations.

[0041] In summary, in the present application, a rotatable support seat 103 is installed at the upper ends of the main frame 101 and the sub-frame 102 to cooperate with the installation of the carriage 104. By rotating the support seat 103 along the main axis at the upper ends of the main frame 101 and the sub-frame 102, the direction of the carriage 104 can be adjusted, which is convenient for unloading and discharging materials from any position near the main frame 101 and the sub-frame 102. The adjustment is convenient, and the carriage 104 installed at the upper ends of the main frame 101 and the sub-frame 102 can be unloaded separately. The carriages of the semi-trailer are used separately, and the unloading is completed through their respective doors, which improves the safety and stability of the unloading of the semi-trailer. Moreover, when unloading, the center of gravity of the lifting of the carriage 104 is reduced, avoiding the risk of the rear-lifting rollover caused by too high a center of gravity, reducing the requirements for the unloading site, and avoiding the vehicle from getting stuck in the soft ground due to the overweight of the goods and being unable to move forward to leave the freight yard. It is not necessary to repeatedly tow and move the vehicle forward to unload all the goods, which is convenient for the operator to control the unloading.

[0042] Embodiment 2

[0043] Referring to Figures 1 - 5 , this is the second embodiment of the present utility model. Different from the previous embodiment, this embodiment provides a unloading assembly 200 for a self-unloading semi-trailer.

[0044] The unloading assembly 200 includes a connecting rod 201 and a hydraulic rod 202 installed at the end of the connecting rod 201. The connecting rod 201 is connected to the middle position of the support seat 103 through a bearing, and the upper end of the hydraulic rod 202 is rotatably installed on the middle side wall of the carriage 104.

[0045] Among them, the connecting rod 201 can rotate along the support seat 103, and then synchronously drive the hydraulic rods 202 at both ends of the connecting rod 201 to rotate. On the basis of the connection of the support seat 103, the carriage 104 is lifted upward, so that the carriage 104 is tilted to start the discharging operation.

[0046] Specifically, an avoidance groove structure matching the hydraulic rod 202 is provided on the side wall of the support seat 103, and the depth of the avoidance groove on the side wall of the support seat 103 is greater than the width of the hydraulic rod 202.

[0047] Among them, adding an avoidance groove matching the hydraulic rod 202 on the side wall of the support seat 103 facilitates the accommodation of the hydraulic rod 202, prevents the hydraulic rod 202 from being damaged by the carriage 104, and also enables the hydraulic rod 202 to have a certain inclination basis during operation, so as to better lift the carriage 104.

[0048] During use, the hydraulic rod 202 is driven to operate by a control device. On the basis of the connection of the support seat 103, the hydraulic rod 202 advances upward to lift the carriage 104, so that the carriage 104 rotates and tilts along the end of the support seat 103 for unloading operation.

[0049] In summary, by controlling the device to drive the hydraulic rod 202 to operate, since the side wall of the support base 103 is provided with a groove structure to avoid the hydraulic rod 202, the hydraulic rod 202 has a certain angular basis during operation, and can more easily lift the carriage 104 along the rotating shaft on the side wall of the support base 103 for blanking operation.
