[0022] The utility model provides Figure 1-3 A check fixture for detecting the interference position of a heat shield shown in the figure comprises a fixing plate a1 and a fixing plate b4 installed on the right side of the fixing plate a1;

[0023] A horizontal plate 5 is clamped between the upper outer walls of the fixing plate a1 and the fixing plate b4 to limit the maximum height position of the heat shield to be detected;

[0024] The lower sides of the fixing plates a1 and b4 are both provided with positioning blocks 3 to be clamped at corresponding clamping positions of the heat insulation cover;

[0025] The upper outer wall of the horizontal plate 5 is fixedly connected with a lifting rod 8, and the left and right outer walls of the horizontal plate 5 are fixedly connected with a plurality of clamping blocks 6 at equal distances. When the interference detection of the position of the heat insulation cover is performed, the fixing plate a1 and the fixing plate b4 are placed on the left and right sides of the heat insulation cover, and the fixing plate a1 and the fixing plate b4 are clamped in the corresponding fixing grooves on the left and right sides of the heat insulation cover through the positioning block 3. Then, the horizontal plate 5 is clamped in the position on the fixing plate a1 and the fixing plate b4 through the lifting rod 8 through the external driving structure, and the spatial distance between the upper side of the heat insulation cover and the lower side of the horizontal plate 5 is detected;

[0026] The lower end outer wall of the block 6 at the center is fixedly connected with a limit strip 10 that runs downward through the fixing plate a1 and the fixing plate b4. A card slot 15 that runs through the left and right is opened inside the right end outer wall of the limit strip 10. A positioning hole 11 that opens to the right is opened inside the right end outer wall of the fixing plate b4 to calibrate the vertical height of the prompt cross plate 5. A positioning rod 16 that is inserted into the positioning hole 11 and the card slot 15 to the right is provided on the right side of the fixing plate b4 to limit the position of the limit strip 10. When it is necessary to detect the position of the heat shield at a higher position, it can be detected by Pull out the positioning rod 16 to the right, then pull up the lifting rod 8 through the external driving structure, and pull out the limit bar 10 upward. When the height of the cross plate 5 is higher than the position of the heat insulation cover, insert the positioning rod 16 to the left into the positioning hole 11 and the card slot 15 to limit the position of the limit bar 10. A plurality of positioning holes 11 and card slots 15 are provided, and the position of the cross plate 5 can be flexibly adjusted according to needs, and the positioning rod 16 can be inserted into appropriate positioning holes 11 and card slots 15 to perform interference detection of the positions of heat insulation covers at different heights.

[0027] like Figure 3 and Figure 4 As shown, the right end outer wall of the limiting strip 10 is fixedly connected with a baffle 12, and the right end outer wall of the baffle 12 is fixedly connected with a gripping rod 13 to drive the positioning rod 16 to move left and right under external force.

[0028] When moving the positioning rod 16 , the positioning rod 16 can be driven to move stably by grasping the gripping rod 13 , so as to perform operations of pulling out and inserting the positioning hole 11 and the card slot 15 .

[0029] like Figure 2 and Figure 4 As shown, a plurality of upwardly opening positioning grooves 14 are provided inside the fixing plate b4 to limit the upward and downward movement space of the limiting strip 10 , and the lower end outer walls of the front and rear side blocks 6 are fixedly connected with positioning strips 9 which penetrate downwardly into the positioning grooves 14 .

[0030] When the limit bar 10 moves up and down, the positioning bar 9 can assist the limit bar 10 in moving up and down, and when the cross board 5 is not installed, the positioning bar 9 and the limit bar 10 can be used to stably lift and place the cross board 5 on the ground.

[0031] like Figure 1 and Figure 4 As shown, a plurality of weight-reducing grooves 7 are evenly spaced inside the outer wall of the upper end of the transverse plate 5 to reduce the weight of the transverse plate 5 , and the diameters of the positioning holes 11 and the clamping grooves 15 are the same.

[0032] The weight-reducing groove 7 can be used to manually lift the lifting rod 8 to drive the weight of the horizontal plate 5 to move up and down, thereby avoiding the situation where the heavy weight affects the operation of the staff and reducing the safety hazards during movement.

[0033] like Figure 1 As shown, the base 2 is fixedly connected between the fixing plate a1 and the fixing plate b4 and the positioning block 3, grooves for the clamping block 6 to be clamped are opened inside the upper end outer walls of the fixing plate a1 and the fixing plate b4, the lifting rod 8 and the cross plate 5 are fixedly connected by welding, and the fixing plate a1 and the fixing plate b4 are fixedly connected to the base 2 and the positioning block 3 by welding.

[0034] When the horizontal plate 5 is clamped and fixed with the fixed plate a1 and the fixed plate b4, the position of the horizontal plate 5 can be limited by clamping between the clamping blocks 6 and the grooves on the left and right sides of the horizontal plate 5. The contact surface between the fixed plate a1 and the fixed plate b4 and the positioning block 3 is increased by the base 2. During the subsequent welding and fixing, the possibility of the positioning block 3 breaking and separating can be reduced.

[0035] The implementation principle of this embodiment is as follows: when performing interference detection on the position of the heat insulation cover, the fixed plate a1 and the fixed plate b4 are placed on the left and right sides of the heat insulation cover, and the fixed plate a1 and the fixed plate b4 are clamped in the corresponding fixed grooves on the left and right sides of the heat insulation cover through the positioning block 3, and then the cross plate 5 is clamped in the position on the fixed plate a1 and the fixed plate b4 through the lifting rod 8 through the external driving structure to detect the spatial distance between the upper side of the heat insulation cover and the lower side of the cross plate 5. When it is necessary to detect the position of the heat insulation cover at a higher position, the positioning rod 16 can be pulled out to the right, and then the lifting rod 8 can be pulled up by the external driving structure, and the limit bar 10 can be pulled out upward. When the height of the cross plate 5 is higher than the position of the heat insulation cover, the positioning rod 16 is inserted to the left into the positioning hole 11 and the clamping slot 15 to limit the position of the limit bar 10. The position of the cross plate 5 can be flexibly adjusted according to needs to perform interference detection on the position of the heat insulation cover.
