[0001] The utility model relates to the technical field of furnace flame television installation, in particular to a furnace flame television fixing mechanism and a convenient loading and unloading device. Background Art

[0002] The furnace flame television device is mainly used for internal monitoring of the combustion conditions in various boiler furnaces, allowing operating personnel to observe the combustion conditions in the furnace in the control room, discover various dangerous conditions in time and take corresponding measures to ensure the safe operation of the boiler.

[0003] Now newly designed boilers must have two furnace flame TVs to monitor the safe operation of the boiler at the same time. However, some boilers were originally designed with only one furnace flame TV installation hole, and it is impossible to install two sets of furnace flame TVs on the front and rear walls of the boiler. In order to install two sets of furnace flame TV probes, holes need to be opened on the water-cooled wall of the boiler, which involves a large amount of engineering work and also poses a safety hazard.

[0027] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0030] Example 1

[0031] Reference Figure 1 , is the first embodiment of the utility model, which provides a furnace flame TV fixing mechanism, including,

[0032] The tube clamping mechanism 100 comprises a base 101, a positioning frame 102 disposed on the base 101, and a double-headed screw 103 rotatably connected to the positioning frame 102, an anti-slip strip is disposed on the outer side of the center of the double-headed screw 103, so that the center of the double-headed screw 103 can be rotated to slide the nut 104, and the nut 104 is threadedly connected to the outer side of the positioning frame 102;

[0033] Furthermore, both ends of the base 101 are arranged in an arc shape, so that it can be adapted to the heat-resistant steel pipe. A positioning slide rod 105 is fixedly installed on the outer side of the nut 104. The positioning slide rod 105 is arranged in a sliding connection with the base 101. Through the setting of the positioning slide rod 105, the nut 104 can only slide but not rotate.

[0034] Furthermore, a clamp arm 106 is fixedly installed on the outer side of the nut 104. The number of the clamp arms 106 is set to be multiple, and the multiple clamp arms 106 are arranged in a mirror-symmetrical manner about the vertical center line of the double-headed screw 103. The clamp arms 106 are in contact with the heat-resistant steel pipe to tighten and fix the heat-resistant steel pipe. A positioning hole 107 is opened on the outer side of the base 101.

[0035] Among them, taking 130T / H gas boiler as an example, the diameter of the water-cooled wall tube of this type of gas boiler is between 65-76mm. In order to ensure the strength of the water-cooled wall tube at the furnace flame TV opening, the general design institute will design the aperture of the furnace flame TV probe to be above 150mm. Then, two heat-resistant steel pipes with an outer diameter of about 72mm are installed in the 150mm hole, and a furnace flame TV probe is installed in each pipe. The two furnace flame TV probes are installed in parallel, and the probe camera uses a small digital camera. In this way, there is no need to change the diameter of the probe tail, and the two sets of furnace flame TV probes do not interfere with each other.

[0036] Usage process: Place the two heat-resistant steel pipes with the furnace flame TV probe installed at the arc-shaped bends at both ends of the base 101, rotate the double-headed screw 103 to make the nuts 104 at both ends slide, use the clamp arm 106 to contact the heat-resistant steel pipe, and then press the heat-resistant steel pipe against the arc-shaped bend of the base 101 to fix it.

[0037] Example 2

[0038] Reference Figure 1-Figure 2 , which is the second embodiment of the utility model, this embodiment further provides a stabilizing mechanism 200, including a trigger block 201, a first spring 202 arranged at the bottom of the trigger block 201, and a limit buckle 203 arranged on the outside of the trigger block 201.

[0039] Furthermore, the trigger block 201 is slidably connected to the inner side of the base 101, and a hook 204 is inserted into the inner side of the limit buckle 203. One end of the hook 204 is fixedly connected to a support column 205, and one end of the support column 205 is fixedly installed with a support platform 206. The support platform 206 and the base 101 are arranged in the same horizontal plane, and a second spring 207 is sleeved on the outer side of the support column 205, and the second spring 207 is in conflict with the inner side of the base 101.

[0040] Usage process: when the heat-resistant steel pipe contacts the trigger block 201, the trigger block 201 slides down to the inside of the base 101. When sliding down, the limit buckle 203 slides down and no longer restricts the hook 204. After the hook 204 loses the restriction, the second spring 207 rebounds and drives the support column 205 to slide, so that the support platform 206 pops out to support the heat-resistant steel pipe, thereby increasing the supporting surface of the heat-resistant steel pipe and playing a stabilizing role. When disassembling, the second spring 207 is compressed by pushing the support platform 206, so that the hook 204 stays above the limit buckle 203. After the heat-resistant steel pipe is taken out, the first spring 202 is used to rebound and drive the trigger block 201 to rise, so that the limit buckle 203 is engaged with the hook 204, and the hook 204 is limited, thereby reducing the occupied area.

[0041] Example 3

[0042] Reference Figure 3-Figure 4 , which is the second embodiment of the utility model, is different from the previous embodiment in that this embodiment provides a convenient loading and unloading device, including the above-mentioned furnace flame TV fixing mechanism; and,

[0043] The fixing mechanism 300 includes a locking rod 301, a threaded section 302 disposed on the locking rod 301, a threaded barrel 303 disposed on the outer side of the threaded section 302 and threadedly connected thereto, and a ring 304 disposed on one side of the threaded barrel 303. A locking head 305 is hingedly connected to the outer side of the locking rod 301.

[0044] Furthermore, the cross-sectional area of ​​the bottom port of the positioning hole 107 is larger than the cross-sectional area of ​​the bottom port of the locking rod 301. The positioning hole 107 is arranged in a "T" shape, so that the locking head 305 can be inserted into the inner two ends of the positioning hole 107. The outer side of the locking head 305 is fixedly connected with an elastic member 306, and the elastic member 306 is fixedly installed on the outer side of the base 101. A clamping plate 307 is fixedly installed at one end of the locking rod 301, and a positioning nut 308 is fixedly installed on one side of the clamping plate 307. A threaded rod 309 is threadedly connected to the inner side of the positioning nut 308, and a splint 310 is fixedly installed on one end of the threaded rod 309. The splint 310 and the splint 307 are arranged in a sliding connection, and a crank 311 is fixedly installed on the end of the threaded rod 309 away from the splint 310.

[0045] Usage process: When not installed, the elastic member 306 contacts the lock head 305, so that the lock head 305 is tilted and fits against the outside of the lock rod 301. When installing, insert the lock rod 301 into the positioning hole 107, and then rotate the threaded tube 303 to make the ring 304 slide and contact the lock head 305, then push the lock head 305 to deflect and snap into the positioning hole 107 for fixation, and then place the clamping plate 307 on the inside of the installation hole of the water-cooled wall, push the threaded rod 309 to rotate and slide by turning the crank 311, and use the splint 310 to press against the outside of the installation hole for fixation.
