Description

Technical Field

[0001] This utility model relates to the field of load-bearing towing technology, specifically a modular heavy-duty load-bearing towing device. Background Technology

[0002] A load-bearing trailer is a specialized piece of equipment installed on a towing vehicle (such as a truck, tractor, or forklift) to carry a specific load and move that load along with the towing vehicle by towing, pulling, or pushing. In the field of heavy transport and logistics, load-bearing trailers are critical equipment, and their performance directly affects transportation efficiency, operational safety, and service life. Currently, traditional heavy-duty tow trucks generally use bolted connections to assemble and fix various components. Disassembly and assembly of each component requires specialized tools, resulting in low maintenance and repair efficiency. In addition, the huge inertial impact force of heavy-duty tow trucks is directly transmitted to the entire tow truck structure and the cargo carried through rigid connection points. This not only causes irreversible fatigue damage to the tow truck's skeleton structure, affecting its service life, but may also damage delicate or fragile goods, resulting in insufficient transportation stability and safety. Utility Model Content

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-7This utility model discloses a modular heavy-duty load-bearing tow truck, including a chassis 1, and further including: a plug-in block 2 disposed on the surface of the chassis 1; a load-bearing tow truck compartment 3 inserted into the top surface of the chassis 1; a mounting bracket 4 inserted into one side of the chassis 1; positioning components 5 fixedly disposed around the perimeter of the load-bearing tow truck compartment 3 and on both sides of the mounting bracket 4; a positioning pin 6 fixedly disposed at one end of the positioning component 5; and a double-rod pin 7 inserted into the interior of the positioning pin 6; the tow truck compartment 3 is opened by means of the positioning components 5, the positioning pin 6, and the double-rod pin 7. The sliding rod 52 connects the bottom of the carrying towing box 3 with the plug-in block 2 on the chassis 1, and connects the mounting frame 4 with the plug-in block 2 on one side of the chassis 1. Then the sliding rod 52 is released, and the reaction force of the alloy spring 53 causes the positioning pin 6 to be inserted into the plug-in block 2. Then the double rod pin 7 is inserted into the insertion hole of the plug-in block 2, further locking the connection point of the chassis 1, the carrying towing box 3 and the towing frame 9. The towing is installed in a boltless modular assembly, which facilitates the inspection and maintenance of each component. Two sets of grooves are provided on one side of the mounting frame 4, and buffer components 8 are fixedly installed inside the grooves. A traction frame 9 is fixedly installed at one end of the buffer components 8. Limiting frames 10 are provided on both sides of the mounting frame 4. The internal threads of the limiting frames 10 have interval limiting members 11. With the setting of buffer components 8 and interval limiting members 11, when the carrying trailer 3 has a large traction or braking inertia, the mounting block 83 drives the elastic group 82 to deform, absorbing the inertial impact force. The damper 12 consumes the stored energy of the elastic group 82, achieving smooth traction and effective braking protection for the heavy carrying trailer 3, reducing the adverse effects of impact load on the trailer structure and transported goods. The interval limiting members 11 limit the deformation range of the buffer components 8, preventing the buffer components 8 from failing due to excessive deformation, providing a reliable safety boundary, and ensuring the durability and stability of the buffer performance.

[0017] Specifically, the positioning component 5 includes a positioning frame 51 fixedly installed on the surface of the carrier carriage 3 and the mounting frame 4. A sliding rod 52 is slidably arranged inside the positioning frame 51. An alloy spring 53 is sleeved on the surface of the sliding rod 52. The two ends of the alloy spring 53 are fixedly connected to the positioning pin 6 and the positioning frame 51, respectively.

[0018] In this embodiment, the sliding rod 52 is pulled open to align the bottom of the carrying trailer box 3 with the plug-in block 2 on the chassis 1, and the mounting frame 4 is aligned with the plug-in block 2 on one side of the chassis 1. Then the sliding rod 52 is released, and the reaction force of the alloy spring 53 causes the positioning pin 6 to be inserted into the plug-in block 2, so that the chassis 1, the carrying trailer box 3 and the traction frame 9 can be quickly spliced ​​and installed.

[0019] Specifically, the surfaces of the plug-in block 2, the carrier carriage 3, and the mounting bracket 4 are all provided with insertion slots that are compatible with the positioning pin 6, the surfaces of the positioning pin 6, the carrier carriage 3, and the mounting bracket 4 are all provided with insertion holes that are compatible with the double rod pin 7, and one side of the carrier carriage 3 and the mounting bracket 4 is provided with a mating groove that is compatible with the plug-in block 2.

[0020] In this embodiment, the insertion slot facilitates the insertion of the positioning pin 6, the insertion hole facilitates the insertion of the double rod pin 7, and the mating slot facilitates the insertion of the plug block 2.

[0021] Specifically, the buffer assembly 8 includes a fixed rod 81, an elastic group 82, and a mounting block 83. Grooves are provided on both sides of the surface of the mounting bracket 4. The fixed rod 81 is fixedly installed inside the groove. The elastic group 82 is slidably installed on the surface of the fixed rod 81. The mounting block 83 is rotatably installed on one end of the elastic group 82.

[0022] In this embodiment, when the carrying trailer 3 has a large traction or braking inertia, the mounting block 83 causes the elastic group 82 to deform, absorbing the inertial impact force. The damper 12 consumes the stored energy of the elastic group 82 to buffer the carrying trailer 3.

[0023] Specifically, the elastic assembly 82 includes a buffer slider 821 that is slidably disposed on the surface of the fixed rod 81. A buffer rod 822 is rotatably disposed on one side of the buffer slider 821. A damping spring 823 is fixedly disposed on one side of the buffer slider 821. The damping spring 823 is sleeved on the surface of the fixed rod 81 and fixedly connected to the inner wall of the groove.

[0024] In this embodiment, when the buffer rod 822 is compressed, it will push the buffer slider 821, and the buffer slider 821 will drive the damping spring 823 to compress and deform, thereby absorbing the inertial impact force.

[0025] Specifically, the interval limiting component 11 includes an adjusting stud 111 threaded through the inside of the limiting frame 10, and one end of the adjusting stud 111 is rotatably connected to the interval limiting piece 112 via a bearing.

[0026] In this embodiment, turning the adjusting stud 111 causes the interval limiting piece 112 to move and press against the mounting bracket 4, thereby limiting the deformation range of the buffer assembly 8 and preventing the buffer assembly 8 from failing due to excessive deformation.

[0027] Specifically, a damper 12 is fixedly installed in the middle of one side of the mounting frame 4, and one end of the damper 12 is fixedly connected to the traction frame 9.

[0028] In this embodiment, the damper 12 is used to consume the energy stored in the buffer assembly 8.

[0029] The working principle and usage process of this utility model: pull the sliding rod 52 away from the side of the carrying trailer box 3, connect the bottom of the carrying trailer box 3 with the plug block 2 on the chassis 1, connect the mounting bracket 4 with the plug block 2 on one side of the chassis 1, and then release the sliding rod 52. The reaction force of the alloy spring 53 causes the positioning pin 6 to be inserted into the plug block 2. Insert the double rod pin 7 into the insertion hole of the plug block 2 to further lock the connection point of the chassis 1, the load-bearing towing box 3 and the traction frame 9, and perform boltless modular splicing installation of the towing, which facilitates the inspection and maintenance of each component. When the traction or braking inertia of the carrying trailer 3 is large, the mounting block 83 causes the elastic group 82 to deform. When the buffer rod 822 is compressed, it will push the buffer slider 821. The buffer slider 821 causes the damping spring 823 to compress and deform, absorbing the inertial impact force. The damper 12 consumes the stored energy of the elastic group 82, buffering the carrying trailer 3 and providing smooth traction and effective braking protection for the heavy carrying trailer 3, reducing the adverse effects of impact load on the trailer structure and transported goods. Turning the adjusting stud 111 moves the interval limit piece 112 to press against the mounting bracket 4, limiting the deformation range of the buffer assembly 8, preventing the buffer assembly 8 from failing due to excessive deformation, providing a reliable safety boundary, and ensuring the durability and stability of the buffer performance.
