Description

Technical Field

[0001] The utility model belongs to the technical field of regulators, in particular to a gear-adding and gear-reducing device for anchor chain production. Background Art

[0002] The medium frequency heating furnace in anchor chain production is one of the key equipment in the anchor chain production process. It is mainly used for induction heating of round steel for subsequent anchor chain weaving. The medium frequency heating furnace generates high-frequency current, which is converted into a magnetic field in the induction coil, causing eddy current and hysteresis loss inside the working furnace body, thereby generating heat to achieve heating of round steel;

[0003] In order to meet the different heating process requirements of the anchor chain, the medium frequency heating furnace needs to adjust the temperature of different gears accordingly. The regulator is a new type of regulator with a microprocessor as the core component. Its various functions can be realized by changing the program (programming), so it is called a programmable regulator;

[0004] Since the operating environment temperature of the medium frequency heating electric furnace is relatively high, the temperature gear regulator used needs to be equipped with a radiator. The traditional heat dissipation method is to set a fan at the end of the gear regulator, and the air inlet and outlet are located on both sides of the end of the regulator. This heat dissipation structure can only dissipate heat at the end of the regulator, with a small coverage space and poor heat dissipation uniformity. Secondly, all the radiators are concentrated at the end of the regulator, resulting in an uncoordinated structure of the entire regulator. The embedded installation requires a larger installation depth, and if the embedded installation adopts the traditional end heat dissipation structure, the air circulation is poor inside the equipment, which affects the heat dissipation effect.

[0005] In order to solve the above problems, the present application proposes a gear-adding and gear-reducing device for anchor chain production. Utility Model Content

[0009] Furthermore, the dustproof plate and the intercepting plate are both inclined downward, and one end of the flow channel faces the heat dissipation cover, and the other end faces the dustproof plate adjacent to the lower end.

[0010] Furthermore, a sliding mounting plate is provided inside the heat dissipation cover, the intercepting plate is fixed on the mounting plate, a guide groove is provided on the mounting plate, and a guide block sliding in the guide groove is fixed on the heat dissipation cover.

[0011] Furthermore, the sliding path of the intercepting plate between the two dust-proof plates is consistent with the sliding path of the guide groove on the guide block.

[0012] Furthermore, a rotating lead screw is provided at the upper end of the heat dissipation cover, an internal thread block is sleeved on the outside of the lead screw, and a connecting rod is hinged between the bottom of the internal thread block and the top of the mounting plate.

[0013] Furthermore, the lead screw is threadedly connected to the internal thread block, and the internal thread block also fits and slides on the top of the inner side of the heat dissipation cover.

[0014] Furthermore, there are two lead screws distributed above the air inlet and the exhaust duct, a transmission component is provided between the two lead screws, and a twisting wheel located at the front end of the heat dissipation cover is fixed on one of the lead screws.

[0015] The utility model has the following beneficial effects:

[0016] The utility model provides a heat dissipation cover, which covers both sides and the rear end of the regulator, and then provides a heat dissipation fan to increase the air flow rate, so that the entire heat dissipation structure is evenly dispersed around the regulator. The overall structure is coordinated, and the heat dissipation space is large and more uniform, which can better adapt to embedded installation conditions and ensure the heat dissipation effect.

[0017] The utility model arranges both the air inlet and the exhaust duct into an openable and closable structure, which is opened when heat dissipation is needed to ensure the heat dissipation effect, and closed when heat dissipation is not needed, thereby preventing dust, debris and the like from entering the heat dissipation cover to affect the heat dissipation, and preventing dust and the like from affecting the internal components of the regulator.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] In the description of the present invention, it should be understood that terms such as "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0032] See also Figure 1-8 As shown, the utility model is a gear-adding and reducing device for anchor chain production, comprising a regulator 1, a heat dissipation cover 2 is arranged outside the regulator 1, a heat dissipation fan 3 is arranged inside the heat dissipation cover 2, a filter screen 4 is also arranged in the heat dissipation cover 2, the heat dissipation cover 2 comprises an air inlet 201 located on one side of the regulator 1 and an exhaust duct 203 located on the other side of the regulator 1, and a rear cover 202 located at the rear end of the regulator 1, a filter screen frame 5 is arranged outside the filter screen 4, the filter screen 4 is installed in the air inlet duct 201 through the filter screen frame 5, and the rear cover 202 is close to one side of the air inlet duct 201 and the exhaust duct 203 A guide plate 6 is provided which is inclined toward the exhaust duct 203. The heat dissipation fan 3 is located in the rear cover 202, and the heat dissipation fan 3 is also installed inclined toward one side of the exhaust duct 203. A dustproof plate 7 is integrally fixed to the outside of the air inlet duct 201 and the exhaust duct 203. A flow channel 8 is provided inside the dustproof plate 7. A slidable intercepting plate 9 is also provided between two adjacent dustproof plates 7. One end of the flow channel 8 is opened and closed by sliding the intercepting plate 9. The opening and closing of the flow channel 8 realizes the opening and closing of the airflow inside and outside the heat dissipation cover 2, which can ensure the cooling effect when dissipating heat, and at the same time ensure the protective effect when not dissipating heat.

[0033] Among them, the dustproof plate 7 and the intercepting plate 9 are both inclined downward, one end of the flow channel 8 is toward the heat dissipation cover 2, and the other end is toward the dustproof plate 7 adjacent to the lower end. In this embodiment, the dustproof plate 7 is inclined downward, and the flow channel 8 has such a hidden structure that it is not easy for external floating to enter even during the heat dissipation process of the heat dissipation cover 2.

[0034] Among them, a sliding mounting plate 10 is provided inside the heat dissipation cover 2, the shutoff plate 9 is fixed on the mounting plate 10, a guide groove 11 is opened on the mounting plate 10, and a guide block 12 sliding in the guide groove 11 is fixed on the heat dissipation cover 2. The sliding path of the shutoff plate 9 between the two dustproof plates 7 is consistent with the sliding path of the guide groove 11 on the guide block 12. In this embodiment, the guide groove 11 and the guide block 12 not only guide the shutoff plate 9 and the mounting plate 10, but also play a supporting and structural strengthening role, thereby ensuring the stable use of the shutoff plate 9 and the mounting plate 10.

[0035] Among them, a rotating screw 13 is provided at the upper end of the heat dissipation cover 2, and an internal thread block 14 is sleeved on the outside of the screw 13. A connecting rod 15 is hinged between the bottom of the internal thread block 14 and the top of the mounting plate 10. In this embodiment, the direction of the force is changed by the connecting rod 15, and the connecting rod 15 is placed at the front end for easy operation. In addition, this transmission method has a compact structure and occupies less space.

[0036] Among them, the screw 13 is threadedly connected to the internal thread block 14, and the internal thread block 14 also slides on the inner top of the heat dissipation cover 2. In this embodiment, the mounting plate 10 is pulled by the moving force of the spiral to achieve the change of the position of the shut-off plate 9. The fit between the outer part of the internal thread block 14 and the heat dissipation cover 2 ensures the horizontal movement of the heat dissipation cover 2 and ensures stable cooperation with the screw 13.

[0037] Among them, there are two screws 13 distributed above the air inlet duct 201 and the exhaust duct 203, and a transmission component is provided between the two screws 13. A screw wheel 16 located at the front end of the heat dissipation cover 2 is fixed on one of the screws 13. In this embodiment, the two screws 13 can be linked by a synchronous pulley or other means. The linkage structure synchronizes the opening and closing of the air inlet duct 201 and the exhaust duct 203, which is convenient for the opening and closing of the heat dissipation cover 2 and has the advantage of easy operation.

[0038] It can be understood that the heat dissipation cover 2 is firstly evenly distributed on the outside of the regulator 1, which increases the heat dissipation area and effect while ensuring the aesthetics and compactness of the structure, and at the same time can ensure the heat dissipation effect of the embedded installation. Secondly, the movable interception plate 9 is cooperated with the dustproof plate 7 to ensure smooth airflow for heat dissipation and to separate the inside of the regulator 1 from the outside when no heat is dissipated, thereby improving the protection.

[0039] A specific application of this embodiment is: according to the requirements of the medium-frequency heating electric furnace for anchor chain production, an increasing and decreasing gear device is installed, and mounting seats at different positions can be set on the outside of the heat dissipation cover 2 according to the installation requirements, and wiring holes can be opened on the heat dissipation cover 2 according to the wiring position of the regulator 1;

[0040] When the regulator 1 does not need heat dissipation; Figure 6As shown, at this time, the dust plate 7 and the intercepting plate 9 are on the same plane, the flow channel 8 is closed, and the regulator 1 and the heat dissipation cover 2 are in a closed state with the outside and cannot communicate with the external airflow;

[0041] When the regulator 1 is cooling: the staff manually rotates the screw wheel 16, the screw wheel 16 drives the lead screw 13 and the internal thread block 14 to generate a spiral, the internal thread block 14 moves and pulls the connecting rod 15, the connecting rod 15 pulls the mounting plate 10 to move upward, the guide groove 11 slides along the guide block 12, the intercepting plate 9 slides between the two dustproof plates 7, and the flow channel 8 is opened. Figure 7 In the state shown, the cooling fan 3 is started, and the cooling fan 3 drives the external air to enter from the air inlet 201, and the filter 4 filters the air dust. The airflow passes through the rear cover 202, and then is guided to the exhaust duct 203 by the guide plate 6 and the tilted cooling fan 3. During the flow of the airflow, the temperature generated inside the regulator 1 is taken away, and the air with heat is finally discharged to the outside from the exhaust duct 203. The airflow needs to pass through the flow channel 8 during the intake and exhaust processes.
