Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of soot blowing for coal-fired boilers, and in particular relates to a tooth-disengaging automatic recovery device for a long telescopic soot blower. Background Art
[0002] In the prior art, if the long telescopic sootblower is dislocated due to a failure of the advance and retract limit position or other reasons, the sootblower cannot continue to operate and needs to be manually restored. In the process of personnel handling the fault, there are risks of personal injury, sootblower burning, and boiler heating surface damage. The utility model solves the technical problem that the sootblower cannot be restored after the teeth are dislocated, and realizes automatic restoration of the sootblower after the teeth are dislocated, which effectively avoids the occurrence of sootblower dislocation failure. Utility Model Content
[0003] The utility model aims to provide a long telescopic sootblower tooth disengagement automatic recovery device to solve the above problems.
[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0005] A long telescopic sootblower tooth disengagement automatic recovery device comprises a rack and a gear matched with the rack, wherein screw holes with two ends passing therethrough are arranged in the rack, and adjustment bolts and single teeth are symmetrically arranged at both ends of the rack, the single tooth is screwed on the adjustment bolt, and positioning blocks are symmetrically penetrated in the rack, the insertion end of the adjustment bolt is screwed in the screw hole and the positioning block, and a tensioning spring is sleeved on the outside of the adjustment bolt, and the tensioning spring is arranged between the single tooth and the positioning block.
[0006] In order to further realize the utility model, the width of the positioning block is greater than the thickness of the rack.
[0007] In order to further realize the utility model, the axis of the screw hole is parallel to the long axis of the rack.
[0008] Compared with the prior art, the utility model has the following beneficial effects:
[0009] The utility model arranges a single tooth on an adjusting bolt, which facilitates adjustment of the spacing between the single tooth and the rack, thereby ensuring that the gear just contacts the single tooth after the soot blower is disengaged; the single tooth is connected with the adjusting bolt by a positioning block to prevent the single tooth from axial rotation; a tensioning spring is interposed between the rack and the single tooth to separate the single tooth from the rack.
[0010] The utility model provides single teeth at both ends of the sootblower rack. When the sootblower is disengaged from the teeth, the sootblower gear shifts the single tooth. Since a tensioning spring is provided between the single tooth and the rack for non-rigid connection, the single tooth reciprocates on the adjusting bolt, and the sootblower cannot continue to move forward. When the sootblower gives a reverse operation signal, the single tooth is pushed to the end of the adjusting bolt, and the sootblower gear returns to the rack under the action of the single tooth to realize automatic return, thereby ensuring that the sootblower gear realizes automatic return after being disengaged from the rack. BRIEF DESCRIPTION OF THE DRAWINGS
[0011] Figure 1 It is a schematic diagram of the structure of the utility model;
[0012] Figure 2 for Figure 1 AA section view;
[0013] The meanings of the accompanying drawings are as follows: 1. rack; 2. screw hole; 3. adjusting bolt; 4. single tooth; 5. positioning block; 6. tensioning spring; 7. gear. DETAILED DESCRIPTION
[0014] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.
[0015] like Figure 1-2 As shown, a long telescopic sootblower tooth disengagement automatic recovery device comprises a rack and a gear matched with the rack, a screw hole 2 with two ends passing through is arranged in the rack 1, the axis of the screw hole 2 is parallel to the long axis of the rack 1, an adjusting bolt 3 and a single tooth 4 are symmetrically arranged at both ends of the rack 1, the single tooth 4 is screwed on the adjusting bolt 3, a positioning block 5 is symmetrically penetrated in the rack 1, the width of the positioning block 5 is greater than the thickness of the rack 1, the insertion end of the adjusting bolt 3 is screwed in the screw hole 2 and the positioning block 5, a tensioning spring 6 is sleeved on the outside of the adjusting bolt 3, and the tensioning spring 6 is arranged between the single tooth 4 and the positioning block 5.
[0016] When the sootblower is disengaged, the gear 7 of the sootblower moves the single tooth 4. Since the tension spring 6 is arranged between the single tooth 4 and the rack 1 and is non-rigidly connected, the single tooth 4 reciprocates on the adjusting bolt 3, and the sootblower cannot continue to move forward. When the sootblower gives a reverse operation signal, the single tooth 4 is pushed to the end of the adjusting bolt 3, and the gear 7 of the sootblower returns to the rack 1 under the action of the single tooth 4 to achieve an automatic return effect, thereby ensuring that the gear 7 of the sootblower can automatically return to the rack 1 after being disengaged.
