[0002] An existing patent (publication number: CN221442291U) discloses a road and bridge engineering protection device. It includes a housing, with a sliding plate fixedly connected to the bottom of the inner wall of the housing. A bidirectional threaded rod is rotatably connected to the right side of the inner wall of the housing. U-shaped plates are threadedly connected to the left and right sides of the outer wall of the bidirectional threaded rod. The bottoms of the two U-shaped plates are slidably connected to the inner side of the sliding plate, and a rotating plate is rotatably connected to the inner side of the U-shaped plates. A top plate is rotatably connected to the top of the outer side of the rotating plate, and a lifting plate is fixedly connected to the top of the top plate. A traveling mechanism is provided at the bottom of the housing, including two fixed boxes, which are respectively fixedly connected to the left and right sides of the bottom of the housing. However, in this device, the equipment relies on the upper part of the housing for road and bridge protection operations. If the equipment needs to be moved, because the housing is a one-piece device, it may not be able to be moved quickly, making transportation difficult. Summary of the Invention

[0003] This utility model addresses the aforementioned shortcomings of the existing technology by providing a road and bridge engineering protective device that, by rotating the hexagonal head at the top of the pressure cylinder, causes the hexagonal head to drive the threaded rod away from the upper part of the guide column, while the pressure cylinder releases the locking of the guide seat, allowing multiple sets of guide seats to be individually detached from the equipment. This enables the equipment base to be disassembled from the protective baffle, facilitating the rapid transfer of the equipment.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A protective device for road and bridge engineering includes an equipment base, a wheel frame, a main support tie rod, a secondary support shaft, a secondary support tie rod, and guide columns. The lower part of the equipment base is fixedly connected to the wheel frame, and the wheel rotates within the wheel frame. The front part of the equipment base is fixedly connected to a lower pin seat, and the rear part of the equipment base is fixedly connected to a limiting plate. The rear part of the limiting plate has an upper pin seat. Both the lower and upper pin seats have pin grooves inside. The lower pin seat corresponds to the internal position of the equipment base, and the pin groove is adapted to the pin. The pin groove connects to the pin, and the pin is inserted into the pin groove. The upper part of the equipment base is fixedly connected to a protective frame. The front part of the equipment base has a main support shaft groove, and the lower part of the main support has a main support shaft. The main support shaft groove is adapted to the main support shaft, and the main support shaft rotates within the main support shaft groove. The upper part of the main support is fixedly connected to a main support tie rod. Both the front of the equipment base and the front of the protective frame have main support tie rod grooves.

[0007] The secondary support shaft rotates inside the secondary support shaft groove. The upper part of the secondary support is fixedly connected to the secondary support tie rod. The secondary support corresponds to the internal position of the protective frame. The rear part of the protective frame has a secondary support tie rod groove, which is adapted to the secondary support tie rod. The secondary support tie rod groove is connected to the secondary support tie rod. Beneficial effects

[0008] 1. During the use of this utility model road and bridge engineering protection device, road and bridge engineering protection operations are carried out through the protective baffle on the upper part of the equipment base. If it is necessary to transfer and move the device, the hexagonal head on the upper part of the pressure cylinder is rotated, so that the hexagonal head drives the threaded rod to disengage from the upper part of the guide column. At the same time, the pressure cylinder releases the locking of the guide seat, allowing multiple sets of guide seats to be detached from the equipment individually. After inserting the main support tie rod on the upper part of the lower pin seat into the main support tie rod groove, the secondary support tie rod on the upper part of the secondary support is inserted into the secondary support tie rod groove to complete the folding. This allows the equipment base to be disassembled from the protective baffle, facilitating the rapid transfer of the equipment.

[0009] 2. During the use of this utility model road and bridge engineering protective device, the guide seat on the side of the protective baffle is guided by the lower end pin seat and the guide column inside the sub-support, and the guide seat is pressed tightly against the side of the guide column by the pressure cylinder to avoid the protective baffle from being misaligned and deformed due to shaking, thereby increasing the stability of the equipment.

[0010] 3. During the use of this utility model road and bridge engineering protection device, the lower end pin seat at the front of the equipment base is connected to the upper end pin seat at the rear of the equipment base for expansion. The pins are used to lock the angle between the lower end pin seat and the upper end pin seat, preventing multiple sets of equipment bases from being misaligned due to shaking, thereby further increasing the stability of the equipment.
