Background

When the hot galvanizing unit is used for producing strip steel, galvanizing is carried out on the strip steel through a zinc pot filled with molten zinc liquid at a process speed, the zinc liquid in the zinc pot is continuously reduced along with the strip steel attached to the surface of the strip steel through the zinc liquid, a zinc ingot is required to be added to meet the liquid level requirement, and the stability of the liquid level height of zinc and the temperature of the zinc liquid is required to be ensured during the zinc adding.

At present, the operation mode of adding a zinc ingot of the existing hot galvanizing unit comprises the following steps:

most of the zinc adding devices adopt a manual mode to add zinc, namely, an electric hoist is controlled manually to hang a zinc ingot to lift. The obvious disadvantages of the above-mentioned method are: (1) the gourd hook and the iron chain below the gourd hook are easy to stick zinc and have high temperature, and the potential safety hazard of manually knocking out the stuck zinc slag is large; (2) the zinc ingot hanging frequency is about 0.5-1.5 hours, and the labor intensity of field workers is high; (3) continuous zinc adding can not be realized, and the liquid level temperature control of the zinc pot is poor.

The traveling mechanism 27 may be a conventional traveling member such as a traveling wheel, and may be driven by a motor, and the specific structure thereof will not be described in detail here. The moving distance of the vehicle body 21 can be precisely controlled by a sensor (e.g., an encoder) or the like inside the travel driving apparatus; it is also possible to arrange a detection element (e.g., a proximity switch or the like as a conventional element) near the travel path 3 of the vehicle body 21 to accurately position the vehicle body 21. Generally, the car body 21 has an upper zinc ingot position and a zinc adding position, the upper zinc ingot position receives a zinc ingot 1, and then the car body moves to the zinc adding position to add zinc to the zinc pot 4.

As shown in fig. 1, the tilting platform 22 is preferably hinged to the front end of the vehicle body 21 to facilitate tilting movement thereof; the tipping driving mechanism 25 can adopt common telescopic driving equipment such as an air cylinder, a hydraulic cylinder or an electric push rod, the output end of the tipping driving mechanism 25 is hinged with the tipping platform 22, and the shell of the tipping driving mechanism 25 is hinged on the vehicle body 21; of course, other tilt driving schemes are also suitable for use in this embodiment, and are not illustrated here. In the configuration shown in fig. 1, the output of the tilting drive 25 is articulated approximately in the middle of the tilting platform 22, so that a relatively high stability of the operation of the tilting platform 22 is achieved, which can of course be adjusted accordingly to the actual circumstances at the site.

In an alternative embodiment, as shown in fig. 1, a buffer unit 28 is provided on the vehicle body 21, and the buffer unit 28 is located on a side of the tilt driving mechanism 25 away from the hinge shaft. The tilting table 22 and the vehicle body 21 can be well protected by arranging the buffer unit 28; the buffer unit 28 includes, but is not limited to, an elastic member using a rubber pad, a compression spring, or the like.

In an alternative embodiment, as shown in fig. 1, a counterweight 29 is disposed at the rear end of the car body 21, and the weight of the counterweight 29 can be adjusted according to the weight of the zinc ingot 1, so that the car body 21 can stably run during the zinc adding operation.

It can be understood that in the present embodiment, the front end is referred to as the end of the corresponding component close to the zinc pot 4, and the rear end is referred to as the end of the corresponding component far away from the zinc pot 4.

The above-mentioned positioning hooks 23 are conventional in the art and may employ a linear rod that is vertically mounted on the output end of the hook driving mechanism 26; an L-shaped rod can also be adopted and comprises a first rod section and a second rod section which are perpendicular to each other, wherein the first rod section is used for carrying the zinc ingot 1, and the second rod section is coaxially connected with the output end of the hook driving mechanism 26. The hook driving mechanism 26 is used for driving the positioning hook 23 to do linear reciprocating motion, and at the zinc adding position, the positioning hook 23 can extend forwards towards the inner side direction of the zinc pot 4 along with the gradual melting of the zinc ingot 1, so that the zinc ingot 1 is ensured to be immersed in a molten pool of the zinc pot 4 all the time. Preferably, the hook movable channel 222 can guide the linear motion of the positioning hook 23 at the same time, so as to ensure the stability of the movement of the zinc ingot 1; in an alternative embodiment, as shown in fig. 2, a plurality of V-shaped guide wheels 223 are arranged in the hook movable channel, the axis of each V-shaped guide wheel 223 is perpendicular to the length direction of the hook movable channel (i.e. parallel to the axial direction of the hinge shaft), the bottom of the positioning hook 23 correspondingly presents a V-shaped ridge structure 231, the V-shaped ridge structure 231 is matched with the V-shaped guide wheel 223, so that the positioning hook 23 can be well guided, and when the positioning hook 23 extends out of the zinc ingot 1, the rigidity of the positioning hook 23 can be increased by the guide structure, so that the operation safety is increased.

The hook driving mechanism 26 can adopt common telescopic driving equipment such as an air cylinder, a hydraulic cylinder or an electric push rod; in this embodiment, preferably, a structure that the motor is matched with the screw rod mechanism is adopted, and the screw rod can be welded with the positioning hook 23; the screw rod mechanism can better bear the torque transmitted by the positioning hook 23, and the working reliability and the stability are high.

In the tilting mobile zinc adding trolley 2 provided by the embodiment, the positioning hook 23 is arranged on the tilting platform 22, and the positioning hook 23 can reciprocate linearly along the tilting platform 22, so that the zinc ingot 1 is horizontally hung on the tilting platform 22 in the processes of feeding the zinc ingot and moving from the feeding zinc ingot position to the zinc adding position, the operation is stable, and the safety is high; the zincification trolley 2 only occupies a certain vertical space due to the tilting of the tilting platform 22 when in the zincification position, but the required vertical space can be provided by the three-dimensional space at the furnace nose 42 of the zinc pot 4, so the space of the hot galvanizing unit occupied by the zincification trolley 2 is small.

Further preferably, the hook driving mechanism 26 is interlocked with the liquid level detection unit 41 configured to the zinc pot 4, for example, in the above structure adopting the motor and the screw rod mechanism to cooperate, the linear motion amount of the positioning hook 23 can be accurately controlled by an encoder configured to the hook driving motor, and the hook driving motor is interlocked with the liquid level detection unit 41 to control, so that the liquid level in the zinc pot 4 is stable without large fluctuation. The interlocking control is a conventional automatic control mode, for example, the hook driving motor and the liquid level detection unit 41 are electrically connected with a central control machine of the hot galvanizing unit, and the automatic control mode is the prior art and does not need additional programming.

The zinc adding trolley 2 can adopt a mode of hanging a zinc ingot 1 by a crown block for hanging; the more preferable scheme is that a mode of automatically supplying zinc ingots 1 is adopted to realize an automatic zinc adding process, the labor intensity of field workers is reduced, and the operation risk is reduced. Specifically, as shown in fig. 1 to 4, a notch 221 suitable for the insertion of a supporting platform 546 of the zinc ingot supply device 5 is formed on the tipping platform 22, and the notch 221 is located between two ends of the hook movable channel 222; it will be understood that the gap 221 extends through one or both of the side walls of the tilting table 22, so as to facilitate the lateral feeding of the zinc ingot 1 by the zinc ingot feeding means 5.

Further preferably, as shown in fig. 1, 2 and 4, a zinc ingot supporting roller way 24 is further disposed on the tilting table 22, the zinc ingot supporting roller way 24 extends from the front end of the notch 221 to the front end of the hook movable channel 222 and/or from the rear end of the notch 221 to the rear end side of the hook movable channel 222, and a roller body of the zinc ingot supporting roller way 24 is axially parallel to the hinge shaft. Obviously, each roller body is arranged in segments and two roller segments are arranged on two sides of the hook movable channel 222, so as to stably support the zinc ingot 1; the zinc ingot supporting roller bed 24 can obviously reduce the friction force between the zinc ingot 1 and the tilting table 22, thereby reducing the resistance of the linear motion of the zinc ingot and protecting the tilting table 22; preferably, zinc ingot supporting roller ways 24 are arranged on the front side and the rear side of the notch 221, the zinc ingot supporting roller way 24 on the front side extends from the front end of the notch 221 to the front end of the hook movable channel 222, and the zinc ingot supporting roller way 24 on the rear side can support the bottom of the zinc ingot 1 on the rear side of the notch 221 when the zinc ingot 1 falls into position.

In an alternative embodiment, as shown in fig. 2, the two ends of the zinc ingot supporting roller way 24 are respectively provided with a side baffle 224, the plate surface of the side baffle 224 is perpendicular to the axial direction of the roller body, and the side baffle 224 is fixed at the front end of the tilting table 22. Through above-mentioned side shield 224, can carry out spacingly to the operation of zinc ingot 1 on zinc ingot bearing roller way 24, can prevent that zinc ingot 1 roll-off zinc ingot bearing roller way 24 and prevent that the direction is uncontrollable when zinc ingot 1 from transferring. Further preferably, the side baffle 224 is further provided with a guide unit for guiding the side wall of the zinc ingot, and the stability and reliability of the operation of adding the zinc ingot can be further improved by additionally arranging the guide unit to guide the movement of the zinc ingot 1; in one of the embodiments the guiding unit comprises at least one gimbaled ball 225, although guiding members in the form of rollers or the like are also suitable for use in this embodiment.

Example two

Referring to fig. 3, an embodiment of the present invention provides an automatic zinc ingot adding system, which includes the first tipping type mobile zinc adding trolley 2 provided in the first embodiment, wherein the trolley body 21 is configured with a travelling rail 3, and the travelling rail 3 extends to the zinc pot 4. The detailed structure of the zincification trolley 2 is not described in detail herein.

In an alternative embodiment, the two travelling tracks 3 are respectively arranged on the operation side and the transmission side of the zinc pot 4, namely two sets of zinc adding trolleys 2 are correspondingly arranged; based on the structure, continuous and seamless zinc adding can be realized, and the stable liquid level of the zinc pot 4 is ensured without large fluctuation; when one set of the zinc adding trolley 2 breaks down, the other set of the zinc adding trolley 2 can still work normally, and the reliable operation of the system is ensured.

As described in the first embodiment, it is preferable to adopt a mode of automatically supplying zinc ingots 1 to realize an automatic zinc adding process, thereby reducing the labor intensity of field workers and reducing the operation risk. Correspondingly, the automatic zinc ingot adding system further comprises a zinc ingot supply device 5, and the zinc ingot supply device 5 is arranged beside the travelling crane track 3.

EXAMPLE III

The embodiment provides a zinc ingot supply device 5, which can be used in the second embodiment and is matched with a zinc adding trolley 2 to realize automatic zinc adding.

As shown in fig. 4-6, the zinc ingot supply device 5 comprises a rack 51, a zinc ingot storage area is formed on the rack 51, a stepping mechanism 54 is arranged below the zinc ingot storage area, a plurality of groups of positioning units are sequentially arranged in the zinc ingot storage area along the stepping direction of the stepping mechanism 54, each positioning unit comprises a fine positioning pin 52 and a coarse positioning pin 53, the axial distance between the fine positioning pin 52 and the coarse positioning pin 53 is equal to the theoretical hole distance between two hanging holes of a zinc ingot 1, and the matching tolerance between the fine positioning pin 52 and the hanging holes is smaller than the matching tolerance between the coarse positioning pin 53 and the hanging holes; the fine positioning pins 52 are arranged in rows, and the coarse positioning pins 53 are arranged in rows; the arrangement direction of each fine positioning pin 52 is parallel to the stepping direction of the stepping mechanism 54, and the axial distance between two adjacent fine positioning pins 52 is the same as the step length of the stepping mechanism 54.

Wherein, the zinc ingot storage area is generally located at the top of the rack 51, in one embodiment, two supporting beams 511 are arranged at the top of the rack 51, the two supporting beams 511 are arranged at intervals, the length direction of the two supporting beams 511 is parallel to the stepping direction of the stepping mechanism 54, and the zinc ingot 1 can be placed on the two supporting beams 511, so that the top surfaces and the upper surfaces of the two supporting beams 511 form the zinc ingot storage area; it is to be understood that the fine positioning pins 52 and the coarse positioning pins 53 are arranged on the two support beams 511, the fine positioning pins 52 are arranged in a row on one of the support beams 511, and the coarse positioning pins 53 are arranged in a row on the other support beam 511; the stepping mechanism 54 can move between the two support beams 511, and comprises a lifting movement and a transverse movement, so that the stepping feeding of the zinc ingot 1 is realized.

When the zinc ingot 1 is cast and molded, two hanging holes are formed, and the hole distance between the two hanging holes is defined as L (the common hanging hole is a round hole, and the hole distance between the two hanging holes is also the distance between the axes of the two hanging holes); ideally, the hole pitches L of the zinc ingots 1 are the same, but due to the influence of factors such as production process and production condition stability, the hole pitches L of the zinc ingots 1 may have a certain deviation, so that the hole pitches of the zinc ingots 1 may fluctuate within a range of L ± n, thereby influencing the alignment between the positioning hooks 23 on the zinc adding trolley 2 and the hanging holes on the zinc ingots 1. The axial distance between the fine positioning pin 52 and the coarse positioning pin 53 in each positioning unit is equal to the theoretical hole distance between two hanging holes of the zinc ingot 1, that is, the axial distance between the fine positioning pin 52 and the corresponding coarse positioning pin 53 is equal to L, so that the fine positioning pin 52 and the coarse positioning pin 53 in each positioning unit can be respectively inserted into the two hanging holes of the zinc ingot 1; obviously, the axes of the fine positioning pins 52 and the coarse positioning pins 53 are parallel to the vertical direction. And because the arrangement direction of each fine positioning pin 52 is parallel to the stepping direction of the stepping mechanism 54, namely the arrangement direction of each rough positioning pin 53 is also parallel to the stepping direction of the stepping mechanism 54, the axial distance between two adjacent fine positioning pins 52 is the same as the step length of the stepping mechanism 54, namely the axial distance between two adjacent rough positioning pins 53 is the same as the step length of the stepping mechanism 54, so that one step length per step of the zinc ingot 1 can be ensured, namely the zinc ingot can run from an upstream positioning unit to a downstream adjacent positioning unit, and the zinc ingot 1 can be sequentially positioned by each positioning unit.

The zinc ingot supply device 5 provided by the embodiment locates the hanging hole of the zinc ingot 1 by adopting the locating pin, the matching tolerance between the fine locating pin 52 and the hanging hole is designed to be smaller than the matching tolerance between the coarse locating pin 53 and the hanging hole, namely, the locating effect of the fine locating pin 52 to the hanging hole is stronger than the locating effect of the coarse locating pin 53 to the hanging hole, namely, the locating precision of the fine locating pin 52 is higher than that of the coarse locating pin 53, thereby ensuring the locating accuracy of the zinc ingot 1, and facilitating the zinc ingot 1 to be accurately hung on the zinc feeding trolley 2. Therefore, the zinc ingot supply device 5 can adapt to the size deviation possibly existing in different cast zinc ingots 1, reduce the quality requirement on zinc ingot casting, ensure the stability and reliability of the operation of the automatic zinc ingot adding system, avoid frequently and manually carrying out the guiding and positioning operation on the zinc ingots 1, reduce the labor intensity of operators and ensure the personal safety.

In one embodiment, as shown in fig. 3-5, the stepping direction of the stepping mechanism 54 is perpendicular to the running track of the zincification trolley 2, and the fine positioning pin row is located on one side of the coarse positioning pin 53 away from the zinc pot 4, or, in the forward zincification running direction of the zincification trolley 2, the fine positioning pin row is located upstream of the coarse positioning pin row, and when the hanging hole positioned by the fine positioning pin 52 is hung by the positioning hook 23 on the zincification trolley 2, the hanging hole positioned by the coarse positioning pin 53 is close to the front side of the zincification trolley 2.

In a further preferred scheme, along the stepping direction of the stepping mechanism 54, the matching tolerance between each fine positioning pin 52 and the hanging hole is gradually reduced, that is, the positioning precision of each fine positioning pin 52 is gradually improved, based on the scheme, the zinc ingot hanging hole can be gradually guided and positioned, the positioning accuracy of the zinc ingot 1 is effectively improved, and meanwhile, the stepping feeding of the zinc ingot 1 is facilitated. Further preferably, the fit tolerance between the fine positioning pin 52 on the outlet side of the zinc ingot storage area and the hanging hole is not more than the fit tolerance between the positioning hook 23 of the zinc adding trolley 2 and the hanging hole, more preferably, the fit tolerance between the fine positioning pin 52 on the outlet side of the zinc ingot storage area and the hanging hole is less than the fit tolerance between the positioning hook 23 of the zinc adding trolley 2 and the hanging hole, not only can the zinc ingot 1 be accurately and reliably hung on the positioning hook 23, but also the positioning accuracy of the zinc adding trolley 2/the positioning hook 23 can be reduced, the zinc adding trolley 2 can hang the zinc ingot 1 without high stopping accuracy, and therefore the production is convenient to go forward.

Further preferably, the specifications of the coarse positioning pins 53 are the same, and a space is reserved for the fine positioning pin 52, so that the zinc ingot 1 is ensured not to be excessively deflected.

In an alternative embodiment, as shown in fig. 4-6, the fine positioning pins 52 are taper pins, and further, each coarse positioning pin 53 may also be a taper pin; the structure of the taper pin with narrow top and wide bottom is adopted, so that the positioning effect of the hanging hole is ensured, a certain guiding effect is achieved, and the zinc ingot hanging hole can be conveniently sleeved. In the above-mentioned scheme that the positioning accuracy of each fine positioning pin 52 is gradually improved, correspondingly, the diameter of the bottom circle of each fine positioning pin 52 is gradually increased, that is, the fit tolerance between each fine positioning pin 52 and the hanging hole is gradually reduced; obviously, the diameter of the bottom circle of each fine positioning pin 52 is not larger than the diameter of the hanging hole, and the diameter of the bottom circle of the fine positioning pin 52 at the outlet side of the zinc ingot storage area is preferably slightly smaller than the diameter of the hanging hole. Typically, the height of each of the fine positioning pins 52 is the same.

In connection with the above-described configuration of the zinc ingot supplying apparatus 5, as shown in fig. 4 and 5, the stepping mechanism 54 includes a stepping base and a traverse-up and down driving unit connected to the stepping base, and the stepping base is located between the fine positioning pin row and the rough positioning pin row. The stepping table is an output part of the stepping mechanism 54, and is adapted to continuously support each zinc ingot 1, and has a length suitable for supporting the maximum amount of zinc ingots stored in the zinc ingot storage area and a width suitable for allowing the zinc ingot storage area to perform lifting and traversing movements, which can be easily determined by those skilled in the art and will not be described in detail herein.

The above-mentioned lifting-and-traversing driving unit may be an existing stepping driving device, and in one embodiment, the lifting-and-traversing driving unit includes a lifting-and-traversing driving structure 542 and a traversing driving structure 543, the lifting-and-traversing driving structure 542 is connected to an output end of the traversing driving structure 543, and the stepping stage is connected to an output end of the lifting-and-traversing driving structure 542. In this embodiment, the lifting driving structure 542 includes 4 spiral lifters, the 4 spiral lifters realize stable and synchronous lifting of the stepping base, and the 4 spiral lifters are connected to the gear motor through the reversing gear box and the coupling; the traverse driving mechanism 543 includes a traverse base 544, the traverse base 544 is driven by a linear driving device such as a cylinder/power push rod to slide along a linear guide 545, and the elevation driving mechanism 542 is mounted on the traverse base 544.

Further optimizing the stepping mechanism 54, as shown in fig. 4 and 7, a zinc ingot limiting frame 541 adapted to accommodate and limit the bottom boss of the zinc ingot 1 is provided at the entrance of the stepping pedestal. Preferably, in the initial position, the zinc ingot limiting frame 541 is located outside the zinc ingot storage area, or outside the rack 51, so as to receive the zinc ingot 1; the shape of the zinc ingot limiting frame 541 is matched with the shape of a boss at the bottom of a zinc ingot, the zinc ingot limiting frame 541 is correspondingly a square frame under the condition that the boss at the bottom of the zinc ingot is a square boss, and the zinc ingot limiting frame 541 is correspondingly a trapezoidal frame with a wide top and a narrow bottom under the condition that the boss at the bottom of the zinc ingot is a trapezoidal boss with a wide top and a narrow bottom, so that the boss at the bottom of the zinc ingot can be well limited; the size of the zinc ingot limiting frame 541 is preferably slightly larger than the size of the corresponding portion of the bottom boss of the zinc ingot, for example, when the bottom boss of the zinc ingot is substantially fastened in the zinc ingot limiting frame 541, the two are preferably in a clearance fit manner. The zinc ingot limiting frame 541 can perform coarse positioning and positioning on the conveyed zinc ingot 1, so that the subsequent zinc ingot can be positioned accurately; the zinc ingot storage area has the advantages that the adjacent distance between the zinc ingots on the zinc ingot storage area is constant, and the distance between the hanging holes of two adjacent zinc ingots (namely the distance between the axis of the hanging hole of the previous zinc ingot and the axis of the hanging hole of the next zinc ingot) is equal to the step distance of the stepping mechanism, so that the accurate positioning effect of the subsequent zinc ingots can be obviously improved.

The stepping mechanism 54 is further optimized, as shown in fig. 7, the outlet end of the stepping pedestal is narrowed and conveniently inserted into the notch 221 of the zinc adding trolley 2, so that after the zinc ingot 1 is hung on the positioning hook 23 on the zinc adding trolley 2, the parts of the two sides of the bottom of the zinc ingot 1 which are not supported by the stepping pedestal can be positioned on the table top of the zinc adding trolley 2, and the zinc ingot 1 can be smoothly handed over from the zinc ingot supply device 5 to the zinc adding trolley 2. This narrowed stepping base constitutes the receiving base 546 of the zinc ingot supply device 5 in the first embodiment.

Based on the zinc ingot supply device 5, the work flow of the automatic zinc ingot adding system is roughly as follows:

(1) a zinc ingot hoisting system (a hoist crane, a forklift or other hoists) hoists the stacked zinc ingots 1 to a zinc ingot limiting frame 541 of the stepping pedestal (at the moment, the stepping pedestal is at a front ingot receiving position and a descending limiting position), and manually hoists and determines the zinc ingots 1 to fall into the zinc ingot limiting frame 541, so as to finish the coarse positioning of the zinc ingots 1;

(2) after the zinc ingot is roughly positioned and positioned in the previous step, the stepping pedestal rises to an ascending limit position, the stepping pedestal moves forwards by one step distance in the next step, the stepping pedestal starts to descend after the stepping pedestal moves to the position, two hanging holes of the zinc ingot 1 are gradually sleeved into a fine positioning pin 52 and a rough positioning pin 53 at corresponding positions in the descending process, then the zinc ingot 1 falls to a supporting beam 511, the bottom surface of the zinc ingot 1 is separated from the stepping pedestal, and the stepping pedestal descends to the descending limit position, so that the transmission and the limit of the zinc ingot 1 by one step distance are completed;

(3) the stepping pedestal moves backwards by a step distance and returns to the initial front ingot receiving position;

(4) repeating the processes (1) to (3) until the zinc ingot 1 stored on the stepping storage table 5 can meet the continuous zinc adding operation for a period of time;

(5) after the zincification operation of one zinc ingot 1 is finished, the zincification trolley 2 moves back to a zinc ingot loading position corresponding to the stepping storage platform 5 from the zincification position, the stepping pedestal executes the processes (2) to (3), the zinc ingot 1 is stepped to the zincification trolley 2, and meanwhile, the hanging hole of the zinc ingot 1 is accurately sleeved in the positioning hook 23 of the zincification trolley 2, so that the continuous feeding of the zincification trolley 2 is realized;

(6) after the zinc ingot 1 is detected to be mounted on the zinc adding trolley 2, the zinc adding trolley 2 moves from the upper zinc ingot position to the zinc adding position, the accurate backward tilting platform 22 stops and starts to tilt to a set zinc adding angle, and the zinc ingot 1 is obliquely mounted on the tilting platform 22 under the restraint of the positioning hook 23;

(7) the positioning hook 23 of the zinc adding trolley 2 and the zinc ingot 1 carried by the same extend forwards in the direction close to the liquid level of the zinc pot under the driving of the hook driving mechanism 26, and zinc is added.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
