DETAILED DESCRIPTION

[0025] In order to make the technical personnel in the prior art can better understand the utility model, the utility model technical scheme is further explained below with the drawings and examples.

[0026] As Figures 1-7 The utility model discloses a turnout plate slide bed surface protection device, including

[0027] Bottom plate 1, bottom plate 1 top right side is equipped with assembly block 11, and the top of assembly block 11 is slide bed surface;

[0028] Cover plate 2, cover plate 2 is buckled on the top of assembly block 11 through connecting mechanism 3, and connecting mechanism 3 includes square frame body 31, and square frame body 31 is fixedly installed on the bottom of assembly block 11, and square frame body 31 is internally provided with square mounting groove 32 on the circumferential side, and square mounting groove 32 internally is fixedly installed with square flexible metal pad 33 on the side close to the center of square frame body 31, and square flexible metal pad 33 is formed by four flexible metal pads, and the upper and lower sides of square flexible metal pad 33 are fixedly connected with the inner wall of the upper and lower sides of square mounting groove 32, and elastic material 34 can generate thrust and push the central part of square flexible metal pad 33 to each other and converge to the inside of square frame body 31, and the inside of square mounting groove 32 is filled with elastic material 34;

[0029] Clamping mechanism 4, clamping mechanism 4 sets up at the top of cover plate 2, is used for clamping and fixing with assembly block 11, and the specific clamping mechanism 4 includes two assembly plates 41, and two assembly plates 41 are distributed in front and back and are assembled on the right side of cover plate 2, and two assembly plates 41 are rotatably assembled with hexagonal sleeve 42 on the side close to each other, and two cover plates 2 are fixedly installed with sleeve 43 on the side away from each other, and two sleeve 43 are slidably and sealingly assembled with sliding block 44 in the inside;

[0030] Two sliding blocks 44 are fixedly installed with threaded rod 45 on the side close to each other, and two threaded rods 45 are inserted into the inside of hexagonal sleeve 42 on the side close to each other, and two sliding blocks 44 are fixedly installed with U-shaped clamping assembly on the side away from each other;

[0031] The front side and the rear side of the hexagonal sleeve 42 are respectively provided with a right-handed thread segment and a left-handed thread segment, and the two threaded rods 45 are respectively threadedly connected with the right-handed thread segment and the left-handed thread segment.

[0032] When it is necessary to protect the sliding bed surface on the top of the assembly block 11, the square frame body 31 is buckled on the assembly block 11, and the bottom of the cover plate 2 abuts against the sliding bed surface. When it is necessary to fix the cover plate 2, in the initial state, the two U-shaped clamping assemblies are away from each other, and when clamping and fixing are needed, the worker rotates the hexagonal sleeve 42. The hexagonal structure is convenient for the worker to hold and also convenient for the worker to use a wrench to rotate. Since the two threaded rods 45 are respectively threadedly connected with the right-handed thread segment and the left-handed thread segment, the rotation of the hexagonal sleeve 42 can drive the two threaded rods 45 to move closer to each other or away from each other. When they move closer to each other, the two sliding blocks 44 are driven to move closer to each other, and then the two U-shaped clamping assemblies are clamped on the front and rear sides of the assembly block 11 until clamping, that is, the position fixing of the cover plate 2 is completed. Conversely, when the two threaded rods 45 move away from each other, the clamping can be released, and the cover plate 2 can be removed. The operation is simple and convenient. The two sliding blocks 44 are respectively sealingly assembled in the sleeve 43, so that the sleeve 43 can be sealed. The sliding connection between the sliding block 44 and the sleeve 43 can prevent the sliding block 44 from rotating.

[0033] The U-shaped clamping assembly comprises a U-shaped clamping rod 46. One end of the U-shaped clamping rod 46 is fixedly connected to the sliding block 44 away from one side of the hexagonal sleeve 42. A through hole 47 is formed in the front right part of the assembly block 11, and one end of the U-shaped clamping rod 46 extends into the through hole 47. In use, when the two sliding blocks 44 move closer to each other or away from each other, the two U-shaped clamping rods 46 are driven to move closer to each other or away from each other. When the two U-shaped clamping rods 46 move closer to each other, they can be inserted into the through hole 47 to complete the limiting, and then the cover plate 2 cannot be opened.

[0034] The U-shaped clamping rod 46 is composed of an L-shaped clamping rod 471 and a straight rod 472. One end of the L-shaped clamping rod 471 is fixedly connected to the sliding block 44 away from one side of the hexagonal sleeve 42. The straight rod 472 is fixedly connected to the other end of the L-shaped clamping rod 471. One end of the straight rod 472 extends into the through hole 47. A plurality of openings 473 are formed around the straight rod 472. After the two straight rods 472 are inserted into the through hole 47, the position of the cover plate 2 can be fixed. Due to the arrangement of the plurality of openings 473, when the device is placed in the inner tube for layering, the liquid for layering can enter the through hole 47 through the openings 473, thereby improving the layering effect.

[0035] The use method of the device is as follows:

[0036] In the initial state, when the inner furnace needs to be carried out with the infiltration layer work, the staff covers the cover plate 2 to the assembly block 11, due to the setting of the elastic material 34, the middle part of the square flexible metal pad 32 protrudes a part to the inside of the square frame body 31 and presents a circular arc state, when covering, the square flexible metal pad 32 is abutted with the top four edges of the assembly block 11, so that the extrusion force is generated to compress the elastic material 34, until the bottom of the cover plate 2 is abutted with the sliding bed surface of the top of the assembly block 11, because the elastic material 34 is compressed, the elastic material 34 continuously releases the pushing force, so that the square flexible metal pad 32 is abutted with the top four edges of the assembly block 11, the sealing property is enhanced, at the same time, the bottom of the cover plate 2 is abutted with the top of the assembly block 11, and they are smooth planes, the sealing property is further improved, so that the infiltration liquid can be effectively avoided to enter between the cover plate 2 and the assembly block 11 when carrying out the infiltration layer work, the surface smoothness of the sliding bed surface is reduced, after the installation is completed, the staff rotates the hexagonal sleeve 42, drives the two U-shaped clamping rods 46 to be close to each other and is inserted into the through hole 47 to complete the locking and limiting, after the infiltration layer is completed, the cover plate 2 is taken off, and the infiltration layer work is completed.
