Description

Technical Field

[0001] The invention relates to the technical field of extraction type welding rod insulation barrels, in particular to an automatic extraction type welding rod insulation barrel. Background Art

[0002] The welding rod insulation barrel is a kind of insulation container for welders to carry on the construction site to store a small amount of welding rods. It is easy to use and carry. The welding rod insulation barrel can keep the welding rod dry. The welding rod will affect the welding quality in some humid places. Therefore, the baked welding rod is placed in the insulation barrel for use at any time to ensure that the welding rod is dry and avoid affecting the welding quality. Therefore, it is widely used in the construction and maintenance of nuclear power plants.

[0003] However, due to the complex on-site construction environment and tight construction schedule, when using the existing welding rod insulation barrel, it is first necessary to use a pull rod or invert the insulation barrel. This process can easily cause the welding rod coating in the insulation barrel to fall off. Secondly, the staff needs to repeatedly open and close the insulation barrel cover, which not only consumes the staff's welding time, but also easily causes the barrel cover to wear and poor sealing, allowing air to diffuse into the insulation barrel, resulting in uneven temperature and humidity inside the insulation barrel, thereby leading to uncertainty in the welding quality of the weld.

[0022] It should be noted that the connection between the barrel bottom 11 and the barrel body 12 , the barrel body 12 and the barrel cover 13 are all provided with a heat insulation layer.

[0025] See also Figure 1 and Figure 5-Figure 8The lifting mechanism 3 includes a base 301 fixed to the top of the barrel bottom 11, a lifting seat 303 arranged in the lifting hole, and a slide plate 308 slidably connected to the base 301. The barrel bottom 11 is fixedly connected to a motor 302, and the motor 302 is connected to the lifting seat 303 by a bevel gear transmission combined with a screw transmission; The bottom side of the lifting seat 303 is smooth, and a rack 304 is fixedly connected to the bottom side of the lifting seat 303. A transmission groove 310 is provided inside the base 301, and a gear 305 and a bidirectional screw rod 306 are provided inside the transmission groove 310. The bidirectional screw rod 306 is connected to the bearing of the base 301, and the gear 305 is fixedly connected to the bidirectional screw rod 306. The rack 304 is meshed with the gear 305. A guard is fixedly connected to the top side of the lifting seat 303; The two-way screw rod 306 is threadedly connected with a slider 307, and the slider 307 is hinged to the slide plate 308; A pressure sensor 309 is provided on the top of the lifting seat 303, and the pressure sensor 309 is used to detect the pressure given by the welding rod during lifting.

[0026] In actual use, the welding rod is pushed to the lifting area 121 under the action of the side pushing mechanism 2, so that the welding rod is located on the lifting seat 303, and the staff presses the button 113 used to drive the lifting mechanism 3 for lifting, and controls the motor 302 to start forward rotation. In the initial state, after the motor 302 is started, the lifting seat 303 is driven to slide upward inside the lifting hole through the bevel gear transmission and the screw transmission; the normal lifting state is that after the lifting seat 303 rises to a certain height, the gear 305 and the rack 304 are engaged for transmission, which indirectly drives the two-way screw rod 306 to rotate, so that the slider 307 moves toward one side close to each other, thereby driving the slide plate 308 to move toward one side close to each other, closing the lifting area 121, and avoiding the accidental drop of multiple welding rods or a single welding rod during the lifting process when lifting the welding rod, which affects the normal welding efficiency.

[0027] The automatic extraction welding rod insulation barrel also includes a lifting system, which is arranged in the display 123. The lifting system includes a program setting module, a collection module, a time module, a control module and an alarm module. The program setting module and the collection module are electrically connected to the temperature sensor 132 and the pressure sensor 309. The program setting module is used to set the internal temperature of the insulation barrel 1 and the interval time of a single welding rod lifting. The program setting module includes a manual mode and an automatic mode. The collection module is used to collect the internal temperature of the insulation barrel 1 and the pressure when the lifting mechanism 3 extracts the welding rod. The time module is used to record the interval time of a single welding rod lifting. The control module is electrically connected to the heating wire 124 and the lifting mechanism 3. The control module is used to automatically extract the welding rod and adjust the interval time of a single welding rod lifting. The alarm module is used to alarm when the lifting is abnormal.

[0028] How to use the automatic extraction welding rod insulation barrel: Step 1: The staff places the insulation bucket 1 vertically or horizontally according to the actual situation during use, selects the automatic mode or manual mode in the program setting module, and sets relevant parameters.

[0029] Specifically, when the manual mode is selected, it is only necessary to set the internal temperature of the insulation barrel 1; when the automatic mode is selected, it is also necessary to set the interval time for a single welding rod lifting, and the set interval time is T. The control module controls the lifting mechanism 3 to extract the welding rod according to the set interval time.

[0030] Step 2: Control the extraction of welding rods. In automatic mode, the control module automatically adjusts the interval time of single welding rod lifting.

[0031] Specifically, the staff manually opens the limit assembly 134 to open the outlet 131. In manual mode, the staff manually presses the button 113 to control the extraction of the welding rod. In automatic mode, the control module automatically controls the lifting mechanism 3 to extract the welding rod. When the welding rod begins to be extracted, the time module starts timing.

[0032] During the welding rod extraction process, the acquisition module collects the pressure value detected by the pressure sensor 309. A pressure interval is set in the acquisition module. The pressure value is recorded as f, and the pressure interval is recorded as [A, F]. A is the minimum reaction force required for normal extraction of the welding rod, that is, the difference between the welding rod's own gravity and the maximum supporting force provided by the inner wall of the barrel body 12. A is not 0. F is the maximum reaction force when the welding rod is normally lifted, that is, the maximum force required to pass through the retaining rings 137 on both sides.

[0033] S1: In the initial state, the acquisition module determines the welding rod extraction state; When f≥A, it is a normal extraction state, and the control module controls the normal welding rod extraction; When f<A, there is no welding rod on the lifting mechanism 3 due to extraction abnormality. The control system controls the lifting mechanism 3 to perform normal operation of extracting the welding rod, and uses the friction between the slide plate 308 and the welding rod to adjust the position of the welding rod in the accommodating area so that the welding rod can be pushed to the lifting area 121 and located on the lifting seat 303. Repeat this process up to three times. If the result is still the same after repetition, the staff will open the insulation barrel 1 for processing.

[0034] S2: In the normal lifting state, the acquisition module determines the welding rod extraction state; When f>F, in order to extract abnormalities, the control system controls the lifting mechanism 3 to stop the normal operation of extracting the welding rod, and lowers the lifting mechanism 3, and uses the friction between the slide plate 308 and the welding rod to adjust the welding rod position in the lifting area 121, so that the welding rod is vertically located on the lifting seat 303. Repeat this process up to three times. If the result remains after repetition, the alarm module will sound an alarm, and the staff will open the insulation barrel 1 for processing.

[0035] When f≤F, the extraction is normal.

[0036] When the staff takes away the welding rod and opens the insulation bucket 1 for processing, the time module stops timing, and the actual interval time from the welding rod lifting to the taking away and opening of the insulation bucket 1 is recorded as t i , i is the number corresponding to the number of welding rods when they are used, i∈[1,n], n is the number corresponding to the total number of welding rods. After the welding rods are extracted and taken away normally, f decreases rapidly. The ideal state is that f decreases to 0.

[0037] It should be noted that when the set interval time T is not reached but the welding rod needs to be lifted, the staff can manually extract the welding rod, and the recorded time is still t i .

[0038] S3: The control module adjusts the single welding rod interval time; The acquisition module also has a counting threshold, which is denoted as X. i When <T, the interval of automatic extraction is short and cannot meet the actual use requirements. The acquisition module performs continuous counting, and the count value is N; In t i When ≥T, the waiting time after the welding rod is extracted is long, the temperature may drop significantly, and the acquisition module performs continuous counting, and the count value is M.

[0039] When N or M ≥ X, the control module recalculates the actual interval time average of the first X groups, and replaces the originally set interval time T with the calculated actual interval time average, thereby ensuring that the welding rod can be automatically extracted in the automatic mode, reducing the time for the staff to manually take out the welding rod, and being able to keep the welding rod within a suitable temperature range. At this time, the actual interval time of the first X groups does not include the time for opening the insulation barrel 1 for processing and recording.

[0040] It should be noted that the control module is also provided with a temperature range that needs to be maintained inside the heat preservation barrel 1. When the temperature detected by the temperature sensor 132 is lower than the temperature range, the control module controls the heating wire 124 to heat the welding rod inside the heat preservation barrel 1, and the alarm module issues an alarm prompt; when the detected temperature is higher than the temperature range, the alarm module issues an alarm prompt, and the staff manually opens the heat preservation barrel 1 for heat dissipation; in order to ensure that the temperature of the extracted welding rod is appropriate and a good welding effect can be obtained, when the actual interval time t recorded is i When the temperature is higher than 1.5T, the alarm module will also sound an alarm prompt, and the staff will manually extract the welding rod again to avoid using welding rods with low temperature and reducing the quality of the weld. At this time, the actual interval time recorded for the manually extracted welding rods will not be included in the adjustment of the single welding rod extraction interval time.

[0041] Through the above-mentioned method, it is possible to ensure that the temperature of the welding rod inside the heat preservation barrel 1 is stable, realize automatic extraction of a single welding rod, and improve the welding efficiency and welding quality of the workers during the welding process.
