[0002] In the construction of precast concrete components, the transportation, installation, and fixing of the components are key links to ensure construction quality and efficiency. Traditional construction methods usually rely on manual operation or simple mechanical devices to connect and fix the components. Manual operation is inefficient, and traditional devices lack sufficient adjustment precision, making it difficult to ensure a tight fit between the precast components and the construction equipment, which can easily lead to construction errors and affect construction quality. At the same time, the fixing methods are simple and lack effective locking mechanisms, which can easily loosen during transportation and installation, posing safety hazards. Furthermore, existing devices are usually complex in structure, inconvenient to install and disassemble, and difficult to achieve rapid docking and separation, thus reducing construction efficiency.

[0003] To address the aforementioned issues, a construction vehicle external connection and fastening device for precast concrete components has been developed. Utility Model Content

Detailed Implementation

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings.

[0020] An external fastening device for construction vehicles of precast concrete components, such as Figure 1 and Figure 2 As shown, it includes a base 1, a sliding fastening frame 2 connected to the front of the base 1, four pre-drilled holes on the front side of the fastening frame 2, a pulley 3 rotatably connected to the bottom of the fastening frame 2, a mounting frame 4 at the rear of the base 1, the mounting frame 4 is a detachable connection structure, two hooks 5 are connected to the upper front side of the mounting frame 4, two rotating parts 6 are rotatably connected to the upper front side of the base 1, each rotating part 6 is rotatably connected to a rotating frame 7, the rotating frame 7 can engage with the adjacent hooks 5, two pins 8 are also slidably connected to the upper front side of the base 1, each pin 8 is equipped with an assisting part, the pin 8 can lock the adjacent rotating parts 6, and an adjustment mechanism 9 is provided at the lower part of the mounting frame 4.

[0021] like Figure 1 , Figure 3 and Figure 4 As shown, the adjustment mechanism 9 includes a drive motor 91. The drive motor 91 is mounted on the lower rear side of the mounting bracket 4. A sliding shaft 92 is slidably connected to the output shaft of the drive motor 91. A spring 93 is connected between the sliding shaft 92 and the output shaft of the drive motor 91. An adjustment screw 94 is snapped onto the sliding shaft 92. The adjustment screw 94 is threadedly connected to the base 1.

[0022] like Figure 1 and Figure 5 As shown, it also includes a fastening mechanism 10, which includes fastening screws 101. Two fastening screws 101 are threadedly connected to the upper rear side of the mounting bracket 4. Each fastening screw 101 is provided with a handle, and each fastening screw 101 is threadedly connected with a threaded disc 102. The threaded disc 102 can lock the adjacent fastening screws 101.

[0023] It should be noted that during the construction of precast concrete components, external connections and fasteners are needed to stabilize, connect, and fix the components, ensuring sufficient strength and stability during transportation, installation, and use. In the use of this device, firstly, the mounting frame 4 is attached to the construction vehicle. Then, the construction vehicle is used to move the device near the precast concrete component, and the position of the clamping frame 2 is adjusted using pulleys 3 to ensure it adheres to the surface of the precast component. To further enhance the stability of the precast concrete component, the pre-reserved space on the clamping frame 2 can be used... The hole is fixed with fasteners. When the construction vehicle drives the device for tightening, there may still be a slight misfit between the precast concrete component and the fastening frame 2. Fine-tuning of the fastening frame 2 is required. The drive motor 91 is started, and its output shaft rotates, causing the sliding shaft 92 to rotate. Initially, the front of the sliding shaft 92 rotates to a state where it may be in a non-clamping contact with the rear of the adjusting screw 94. As the drive motor 91 rotates the sliding shaft 92, the adjusting screw 94 will press the sliding shaft 92 backward, while the spring 93... When the groove on the sliding shaft 92 rotates to correspond with the protrusion on the adjusting screw 94, the spring 93 and the sliding shaft 92 will disengage from the compressed state, thereby causing the sliding shaft 92 to engage with the adjusting screw 94. This drives the adjusting screw 94 to rotate, which in turn drives the clamping frame 2 to rotate until the clamping frame 2 is adjusted to a suitable position, thereby adjusting the degree of adhesion between the clamping frame 2 and the precast concrete component. To further enhance the stability of the construction vehicle and the installation of the device, the handle on the fastening screw 101 can be rotated to move the fastening screw 101 along the rear side of the mounting frame 4. The threaded movement allows the threaded disc 102 to rotate, locking the adjacent fastening screw 101 to prevent it from loosening. This improves construction and transportation safety. After the external operation is completed, the pin 8 is pulled out to disengage the adjacent rotating part 6 and mounting bracket 4 from the locked state. Then, the rotating part 6 is rotated upwards to disengage the adjacent rotating bracket 7 from the hook 5, thereby removing the mounting bracket 4 from the base 1. At the same time, the drive motor 91 is removed, and the sliding shaft 92 is disengaged from the adjusting screw 94 for future use.

[0024] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
