[0025] The following is combined with Figure 1 To Attachment Figure 5 The principles and features of the present invention are described, and the examples given are only used to explain the present invention, and are not used to limit the scope of the present invention.

[0026] A heating and heat-insulating riser plate, comprising an insulation block 1, a sleeve 2, a ratchet shaft 3 and a locking rope 4. It should be noted that this product is a customized product, and the corresponding modulus (i.e., the number of insulation blocks) needs to be calculated based on the circumference of the outer wall of the riser. The longitudinal section of the insulation block 1 is trapezoidal, and a plurality of insulation blocks 1 are arranged linearly. The material of the insulation block 1 continues to use traditional quartz sand material. An insulation layer 13 is connected to the bottom of the insulation block 1, and the long bottom parts of the insulation block 1 are interconnected through the insulation layer 13, and the remaining parts are separated from each other. The insulation layer 13 also uses traditional insulation cotton material.

[0027] The outermost insulation block 1 is connected with a ratchet shaft 3, Figure 1 A ratchet shaft 3 is embedded in the rightmost insulation block 1, and sleeves 2 are embedded in all insulation blocks 1, that is, sleeves 2 correspond to insulation blocks 1 one by one. One end of a lock rope 4 is fixed to one of the insulation blocks 1, and this insulation block 1 is adjacent to the insulation block 1 on which the ratchet shaft 3 is installed. The other end of the lock rope 4 passes through the sleeve 2 in the insulation block 1 and is connected to the ratchet shaft 3.

[0028] Specifically, the ratchet shaft 3 includes an axle body 6, a first limiting flange 7, a second limiting flange 8, a ratchet 9 and a pawl 10. The axle body 6 passes through the insulation block 1, and the first limiting flange 7 and the second limiting flange 8 are disposed at both ends of the axle body 6. The first limiting flange 7 is cylindrical and connected to one end of the axle body 6 by welding. A plurality of operating holes 14 are distributed along the circumferential array of the first limiting flange 7. The function of the operating hole 14 is to facilitate the rotation of the axle body 6. The second limiting flange 8 is plate-shaped, and a threaded cylinder should be pre-embedded at one end of the insulation block 1 to fix the second limiting flange 8. The other end of the axle body 6 passes through the second limiting flange 8 and forms a rotational connection with the second limiting flange 8. The ratchet 9 is fixedly connected to one end of the axle body 6 and fits with the second limiting flange 8. One end of the pawl 10 is rotationally connected to the second limiting flange 8, and the other end of the pawl 10 is connected in cooperation with the ratchet 9. The cooperation between the ratchet 9 and the pawl 10 can make the axle body 6 rotate in one direction, so that the lock rope 4 is tightened more and more. Two locking holes 11 in different directions are arranged on the shaft body 6. One end of the lock rope 4 is inserted into the locking hole 11 and then the shaft body 6 is rotated to tighten the lock rope 4. The lock rope 4 should be made of steel wire rope, and a cavity 12 for accommodating the lock rope 4 is arranged in the insulation block 1 connected to the ratchet shaft 3.

[0029] After the device is wrapped around the riser, a gap will be left between two adjacent insulation blocks 1, and the gap should be filled with molding sand 5 for sufficient insulation.

[0030] The device securely fixes the heat-insulating block 1 on the outer wall of the riser through the ratchet shaft 3 .

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
