[0023] The units described as separate components may or may not be physically separate, and the components shown as units may or may not be physical units, that is, they may be located in one place or distributed across multiple network units. Some or all of these units may be selected to achieve the purpose of this embodiment according to actual needs.

[0024] In addition, each functional unit in each embodiment of the present invention may be integrated into one processing unit, or each unit may exist physically separately, or two or more units may be integrated into one unit. Example 1

[0025] like Figure 2-Figure 4 As shown, in this example, the positions of front, back, left, right, up and down are described as follows: Figure 4 The positional relationship is based on the side baffle 2 of the present invention, and its structure includes: two pillars 25 and an arc-shaped plate 22 arranged on the pillars 25, the top of the arc-shaped plate 22 is provided with an arc-shaped groove A24, and the side is provided with an arc-shaped groove B23, the arc-shaped groove A24 is provided with a slide assembly 21, and the slide assembly 21 includes: a slide 211; a traction device 26 and a fixed pulley 27 are respectively provided at both ends of the arc-shaped groove A24, one end of the traction line 28 is fixed to one end of the slide 211, and the other end passes around the traction device 26 and the fixed pulley 27, and is fixed to the other end of the slide 211, so that the traction device 26 can drive the slide 211 to slide in the arc-shaped groove A24; a card slot 221 is also provided on the slide 211.

[0026] More specifically, the traction wire 28 is a steel strand.

[0027] More specifically, the traction device 26 includes a motor, the output shaft of the motor drives the driving wheel to rotate, and the driving wheel and the fixed pulley 27 are both provided with a circumferential wire groove for the traction wire 28 to be embedded.

[0028] More specifically, there are extended plates 212 on both sides of the lower part of the slide 211, and a support rod 213 for fixing the traction line 28 is provided at one end of the extension plate 212 far from the slide 211; the bottom of the slide 211 and the extension plate 212 are on the same cylindrical surface, and the cylindrical surface is the same as the cylindrical surface where the top of the arc plate 22 is located. This shape design can prevent the slide assembly 21 from getting stuck when sliding.

[0029] More specifically, the front end of the slide 211 is also provided with a connecting plate 220, and a guide rod 219 is fixed to the connecting plate 220 by two or more bolts. It is necessary to provide a plurality of fastening bolts here to prevent the guide rod from rotating. A screw 218 is screwed into the lower part of the guide rod, and a roller A217 is installed at the end of the screw 218. The roller A217 rolls in the arc groove B23, and the outer diameter of the roller A217 is equal to the groove width of the arc groove B23; the structure and size setting of the guide components such as the connecting plate 220, the guide rod 219, the screw 218, and the roller A217 can ensure that the bottom surface of the slide 211 is always in contact with the top of the arc plate 22, thereby preventing the slide component 21 from jumping during movement and affecting the plastering effect.

[0030] More specifically, a downwardly protruding block 214 is provided at the center of the bottom surface of the slide 211, and a roller B216 is provided on the left and right sides of the bottom of the block 214. When the bottom of the slide 211 and the extension plate 212 are close to the top of the arc-shaped plate 22, the block 214 is inserted into the arc groove A24, and the roller B216 is against the bottom of the arc groove A24. The block 214 is also provided with left and right through-holes 215. One end of the traction line 28 is fixed to the support rod 213 on the right extension plate 212, and the other end bypasses the driving wheel, passes through the wire hole 215, bypasses the fixed pulley 27, and is fixed to the support rod 213 on the left extension plate 212; the design of the block 214 and the roller B216 reduces the friction during the movement of the slide assembly 21, and the wire hole 215 constrains the range of movement of the traction line 28 to prevent entanglement. Example 2

[0031] like Figure 5-Figure 6 As shown, the prefabricated shield segment finishing structure 1 of the present invention includes: a central beam 12, with blocks 11 at both ends of the central beam 12, a splint 13 at the lower part of the central beam 12, and a scraper 14 at the bottom of the splint 13; the outside of the block 11 is wrapped in a rubber sleeve 15, the lower part of the rubber sleeve 15 is diamond-shaped, conical or spindle-shaped, and the upper part is a handle 16; the block 11, the central beam 12, and the splint 13 are made of hard materials to improve the main strength of the finishing structure and enhance its durability, and the scraper 14 and the rubber sleeve 15 are made of elastic materials.

[0032] More specifically, the clamping block 11 and the center beam 12 are an integral structure or a plug-in connection. If the clamping block 11 and the center beam 12 are an integral structure, the clamping block 11 and the center beam 12 are injection molded or cast as a whole. If the clamping block 11 and the center beam 12 are plug-in connected, the clamping block 11 is provided with a groove for inserting the center beam 12; the splint 13 and the center beam 12 are an integral structure or fixed by bolts. If the splint 13 and the center beam 12 are an integral structure, the splint 13 and the center beam 12 are injection molded or cast as a whole. If the splint 13 and the center beam 12 are bolted, the splint 13 and the center beam 12 are provided with screw holes in opposite positions; the upper part of the scraper 14 is stuck in the T-shaped slot at the bottom of the splint 13.

[0033] More specifically, the clamping block 11 is embedded in a slot at the lower portion of the rubber sleeve 15 , and the shape and size of the slot match those of the clamping block 11 .

[0034] More specifically, the hard material is stainless steel, the elastic material is silicone, and the surface of the rubber sleeve 15 has an orange peel texture.

[0035] More specifically, after the slot of the rubber sleeve 15 is inserted into the block 11, the thickness of the elastic material layer is equal to 1 cm, which facilitates the rubber sleeve 15 to be inserted and removed from the slide seat through elastic deformation, thereby realizing rapid assembly and disassembly of the plastering structure.

[0036] In this example, the rubber sleeves at both ends of the plastering structure can utilize their own elastic deformation and be installed and removed from the slide described in Example 1 by plugging and unplugging, and the slide is pulled from one end of the shield segment to the other end by a traction device to realize mechanized plastering processing. Example 3

[0037] like Figures 1-6 As shown, the shield segment casting mold that is easy to clean described in the utility model includes a base mold 3 and end plates 4 that are movable at the left and right ends of the base mold 3 driven by a driving device, and side baffles 2 that are movable at the front and rear ends of the base mold 3. After the end plates 4 and the side baffles 2 are surrounded by the base mold 3, a cavity for casting shield segments is formed. The side baffles 2 are as shown in Example 1, and the plastering structure is as shown in Example 2. In this example, the traction devices of the side baffles on both sides drive the slide assembly to proceed synchronously to ensure that the positive projection of the plastering structure is always perpendicular to the travel direction of the slide assembly.

[0038] The utility model improves the side baffle of the existing shield segment casting mold, opens an arc groove on the top thereof, installs a slide assembly in the arc groove, and then arranges a traction device at one end of the arc groove to drive the slide assembly to slide in the arc groove, thereby driving the finishing structure on the slide assembly to be plugged in and unplugged to perform finishing processing on the cast shield segment. The utility model saves manpower, improves processing efficiency, and is convenient for loading and unloading.

[0039] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
