[0023] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure. The present invention is further described in detail below in conjunction with the accompanying drawings.

[0025] T-shaped precast beam bridge edge protection device, such as Figure 1-5 As shown, it includes a telescopic mechanism, a tripod support device and a connecting lever 7. The tripod support device is slidably mounted on the outer surface of the telescopic mechanism. The telescopic mechanism is provided with a V-shaped marble spring claw 2 and a spring pick 8. The end of the telescopic mechanism is provided with a through hole adapted to the connecting lever 7. The connecting lever 7 passes through the through hole at the end of the telescopic mechanism and is connected to the next protective device, thus forming a three-dimensional multi-faceted protective device. The structure of each protective device is consistent. The adaptability of the protective device is improved by adjusting the height of the telescopic mechanism. The connecting lever 7 passes through the through hole at the end of the telescopic mechanism and is connected to the adjacent protective device. This design allows the protective device to be adjusted as needed, and when the construction work order changes, the interval between the two protective devices can be flexibly changed. The protective device has a simple structure and is easy to operate. It can better guarantee the safety of construction workers in all aspects and effectively improve the installation and disassembly efficiency of the edge protective device. The V-shaped marble spring claw 2 and the spring pick 8 are both elastic devices. When pressed, they can be close to the outer surface of the telescopic mechanism and can rebound when released. The connecting lever 7 is a steel bar.

[0026] The telescopic mechanism includes a support rod 1 and a pre-buried steel pipe 5 for the bridge deck. The support rod 1 is plugged into the pre-buried steel pipe 5 for the bridge deck. A V-shaped marble spring claw 2 and a spring pick 8 are installed on the support rod 1. The tripod support device is slidably installed on the support rod 1. A through hole is opened at one end of the support rod 1 away from the pre-buried steel pipe 5 for the bridge deck. A reserved through hole 501 is opened on the pre-buried steel pipe 5 for the bridge deck. The reserved through hole 501 is adapted to the V-shaped marble spring claw 2. The V-shaped marble spring claw 2 is snap-connected to the reserved through hole 501. 2 and the design of the reserved through hole 501, the support rod 1 can be snap-connected and disassembled by a simple pressing operation. When the support rod 1 is inserted into the pre-embedded steel pipe 5 of the bridge deck, the V-shaped marble spring claw 2 is squeezed and retracted until it reaches the reserved through hole 501 and pops out to complete the snap connection, which effectively improves the operability of the device and enables the task to be completed more efficiently when rapid adjustment or configuration change is required. The number of V-shaped marble spring claws 2 in a group is two symmetrically arranged, which can be set as one or more groups according to requirements.

[0027] There are four spring picks 8 in a group, which are circular protrusions on the outer surface of the support rod 1. Like the V-shaped marble spring claw 2, they can be one group or multiple groups for easy adjustment. The spring pick 8 is located between the V-shaped marble spring claw 2 and the through hole. The spring pick 8 is in a triangular shape with a bevel close to the support rod 1. This design makes it easy and labor-saving to install the tripod support device. When the tripod support device slides under the spring pick 8, the spring pick 8 rebounds and presses against the tripod support device, providing a support surface for the tripod support device of the rear support leg after adjustment, thereby increasing its stability.

[0028] The tripod support device includes a connecting ring 3 and a tripod 4. The tripod 4 is movably connected to the connecting ring 3. The connecting ring 3 is slidably connected to the telescopic mechanism. An anti-skid friction gasket 6 is installed at one end of the tripod 4 away from the connecting ring 3. The movable connection between the connecting ring 3 and the tripod 4 and the existence of the telescopic mechanism make the support device more flexible and can adapt to different terrains and work requirements. The connecting ring 3 can be removed by pressing the spring paddle 8. The anti-skid friction gasket 6 ensures that the support device has better stability when placed, improves the safety of the support device, and avoids unnecessary sliding or movement. The connecting ring 3 is compatible with the support rod 1, and the three support legs of the tripod 4 can be adjusted vertically 180° on the connecting ring 3.

[0029] Working principle: prepare several pre-buried steel pipes 5 for the bridge deck, support rods 1 and tripod support devices according to the actual situation on site, first install the pre-buried steel pipes 5 for the bridge deck, further insert the support rods 1 into the pre-buried steel pipes 5 for the bridge deck, and use the V-shaped spring claws in the pipe to complete the snap connection with the reserved through holes on the pre-buried steel pipes 5 for the bridge deck, so that the support rods 1 and the pre-buried steel pipes 5 for the bridge deck are vertically fixed, and then the tripod support device is put on the support rod 1 through the connecting ring 3, and slides downward until it slides under the spring pick 8. When the connecting ring 3 slides down to the spring pick 8, the spring pick 8 under pressure is retracted and pressed against the outer surface of the support rod 1. When the connecting ring 3 slides under the slide, the spring pick 8 rebounds to provide a support surface for the tripod support device. At this time, adjust the tripod 4 to complete the oblique support and fixation, and finally complete the horizontal connection and fixation through the connecting lever 7 through the through hole at the top of the support rod 1, which can realize single-sided, double-sided or even multi-sided edge protection;

[0030] When disassembly is required, first pull out the connecting lever 7, and then vertically press the V-shaped marble spring claw 2 of the support rod 1 and pull the support rod 1 upward to complete the disassembly. The tripod support device can be slid out by pressing the spring paddle 8. If the tripod support device is not disassembled, the tripod 4 can also be folded up and pressed close to the support rod 1 for easy transportation and storage.

[0031] The above description is only a preferred embodiment of the present invention and does not constitute any other form of limitation to the present invention. Any technician familiar with the profession may use the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes for application in other fields. However, any simple modification or equivalent change made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
