[0010] Preferably, the tops of the three pocket boards are symmetrically fixedly connected with connecting ropes, and one end of the multiple connecting ropes is respectively fixedly connected to the three outer surfaces of the guardrail. Through the setting of the connecting ropes, a certain supporting force can be provided to the unfolded pocket boards to ensure their stability.
[0011] Preferably, the tops of the three pocket plates are provided with collection troughs, and the front surface of the guardrail is provided with a protective door. By providing the collection troughs, welding slag and materials can be protected, further reducing the risk of falling.

[0022] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.
[0023] 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 than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0024] See also Figure 1-Figure 5 The utility model provides a technical solution: a bottom protection device, including a protection component 2; the protection component 2 includes a guardrail 201, and the outer surfaces of three sides of the guardrail 201 are symmetrically fixedly connected with connecting blocks 203 near the bottom. The multiple connecting blocks 203 are divided into three groups, and the inner surfaces of the three groups of connecting blocks 203 are rotatably connected with rotating shafts 208. The outer surfaces of the three rotating shafts 208 are fixedly connected with pocket plates 202, and the tops of the three pocket plates 202 are fixedly connected with mounting blocks 205. The bottoms of the three mounting blocks 205 are each provided with a fixing groove 213, and the inner surfaces of the three fixing grooves 213 are each provided with a clamping block 207. The top of the guardrail 201 is provided with multiple clamping slots 210.
[0025] like Figure 3-Figure 4 As shown, multiple clamping blocks 207 are respectively matched with multiple clamping slots 210, and the cross-sections of the three clamping blocks 207 are all inclined, so that when the clamping blocks 207 are inserted into the clamping slots 210, the position of the pocket plate 202 can be limited.
[0026] like Figure 3-Figure 5As shown, the inner tops of the three fixed grooves 213 are symmetrically and movably penetrated by sliding rods 212, and the outer surfaces of the multiple sliding rods 212 are sleeved with springs 211. The multiple sliding rods 212 are divided into three groups, and the bottoms of the three groups of sliding rods 212 are fixedly connected to the tops of the three blocks 207. By pulling the sliding rods 212, the springs 211 can be compressed and the blocks 207 can be moved along the inside of the fixed grooves 213.
[0027] like Figure 2-Figure 5 As shown, the tops of the three sets of sliding rods 212 are fixedly connected to a fixing plate 206, and multiple springs 211 are respectively located on the inner sides of the three fixing grooves 213. The setting of the fixing plate 206 makes it convenient for staff to pull the sliding rods 212 to move.
[0028] like Figure 3 As shown, the tops of the three pocket panels 202 are symmetrically fixedly connected with connecting ropes 204, and one end of the multiple connecting ropes 204 is fixedly connected to the three outer surfaces of the guardrail 201 respectively. Through the setting of the connecting ropes 204, a certain supporting force can be provided to the unfolded pocket panels 202 to ensure its stability.
[0029] like Figure 1-Figure 2 As shown, the tops of the three scoop plates 202 are provided with a collecting trough 214, and the front surface of the guardrail 201 is provided with a protective door 209. The setting of the collecting trough 214 can protect the welding slag and materials, further reducing the risk of falling.
[0030] like Figure 1 As shown, a steel-concrete composite beam construction work platform for high-speed construction includes any of the above-mentioned schemes, including a lifting platform 1, the top of the lifting platform 1 is fixedly connected to the bottom of the guardrail 201, and under the setting of the lifting platform 1, the guardrail 201 can be raised and lowered with the platform.
[0031] The method of use and working principle of this device are as follows: the lifting platform 1 adopts the automatic scissor lift aerial work platform of HKG0810 model. During the construction of the steel-concrete composite beam bridge, after the lifting platform 1 is brought to the construction location, the protective door 209 is opened, the workers and materials are moved to the working area on the lifting platform 1, the protective door 209 is closed, and the lifting platform 1 is started, so that the workers are lifted to a high place to construct the composite beam. Before construction, by pulling the fixed plate 206 upwards, the spring 211 is compressed and the sliding rod 212 is moved upwards, so that the clamping block 207 is disengaged from the clamping slot 210, and then the mounting block 205 is pushed to make the pocket plate 202 rotate along the connecting block 203 and the rotating shaft 208 to unfold. After rotating 90 degrees, the two connecting ropes 204 will be straightened, providing a certain support force for the unfolded pocket plate 202 to ensure its stability, and then construction is carried out. During the construction process, the workers can be protected by the guardrail 201, and the pocket plate 20 2 can collect tools and welding slag that have fallen accidentally, prevent them from falling, and protect the safety of people and equipment below. When the pocket plate 202 needs to be stored, it is lifted up by the connecting rope 204, so that the pocket plate 202 rotates along the rotating shaft 208, and then the edge of the pocket plate 202 is pulled to pull the mounting block 205 along the direction of the guardrail 201. During the pulling process, the guardrail 201 will squeeze the inclined surface of the card block 207, so that the card block 207 moves toward the fixing groove. 213 moves and drives the spring 211 to be compressed. When the bottom of the mounting block 205 is in contact with the top of the guardrail 201, the fixing groove 213 is aligned with the card slot 210. Therefore, under the action of the spring 211, the card block 207 is pushed downward and inserted into the card slot 210, and the pocket plate 202 is limited and fixed, and the pocket plate 202 is stored on the outside of the guardrail 201, which is convenient for unfolding and storing the pocket plate 202, making the construction process smoother and reducing manual operation and time costs.
