Description

Technical Field

[0001] This application relates to the field of drive technology, and in particular to a quay container crane drive with a heat dissipation device. Background Technology

[0002] As large-scale mechanical loading and unloading equipment at container terminals, the operational efficiency of quay cranes directly affects the overall production and operation efficiency of the terminal. A quay crane has four main mechanisms—lifting, trolley, overhead trolley, and tilting—all driven by frequency converters and other drive devices located in the electrical room.

[0003] The drive unit includes a power control board, a drive control board, a capacitor assembly connecting the two control boards, and a circuit breaker. Both the power control board and the drive control board are installed in an electrical control cabinet. During long-term operation, the cabinet accumulates significant heat. Since the power control board and drive control board primarily rely on passive cooling, prolonged operation can cause them to overheat and even burn out. This triggers a fault alarm from the drive unit, severely impacting the efficiency and safety of dockside loading and unloading operations. Utility Model Content

[0004] This application provides a method to alleviate heat buildup inside the electrical control cabinet and reduce the probability of overheating and burning of the two control boards.

[0005] The quay crane drive with a heat dissipation device provided in this application adopts the following technical solution:

[0006] A quay container crane drive with a heat dissipation device includes an electrical control cabinet, a power control board and a drive control board disposed on one side of the electrical control cabinet, and a power failure protector. The two control boards are arranged in parallel. The characteristic feature is that the electrical control cabinet is further provided with a heat dissipation device, which includes a first mounting plate, a second mounting plate, a fixing plate connecting the first mounting plate and the second mounting plate, and a cooling fan disposed on the fixing plate. The fixing plate has a fixing through hole penetrating both end faces for mounting the cooling fan, and the output port of the cooling fan corresponds to the control board.

[0007] By adopting the above technical solution, a cooling fan is installed inside the electrical control cabinet. The output port of the cooling fan corresponds to the two control boards, ensuring that the cooling fan can directly cool the power control board and the drive control board, thereby alleviating the heat accumulation in the electrical control cabinet and reducing the probability of the two control boards burning due to high temperature.

[0008] Optionally, the output shaft of the cooling fan is parallel to the length direction of the electrical control cabinet, and ventilation holes and heat dissipation holes are respectively provided at both ends of the length direction of the electrical control cabinet.

[0009] By adopting the above technical solution, the output shaft of the cooling fan is parallel to the length direction of the electrical control cabinet, which creates a narrow channel for airflow inside the electrical control cabinet. Compared with the cooling fan axis being parallel to the width direction of the electrical control cabinet, this results in a more ideal heat dissipation effect. At the same time, the setting of ventilation holes and heat dissipation holes allows the gas inside the electrical control cabinet to circulate with the outside air, increasing the exchange speed of internal and external gases and improving the heat dissipation effect.

[0010] Optionally, the cooling fan is located on the side of the mounting plate away from the control board.

[0011] By adopting the above technical solution, the cooling fan is located on the side of the fixed plate away from the control board, so that the air blown out by the cooling fan can be directly blown onto the control board through the fixed through hole.

[0012] Optionally, the fixing plate has multiple mounting holes on the outside of the fixing through hole. The mounting holes are spaced circumferentially along the axis of the fixing through hole. The cooling fan has locking holes corresponding to the mounting holes, and locking elements are provided in the locking holes. The fixing plate and the cooling fan are fixed by the locking elements passing through the locking holes and the mounting holes.

[0013] By adopting the above technical solution, the installation method of the cooling fan and the mounting plate is disclosed. When installing the cooling fan, the cooling fan is placed on the side of the mounting plate away from the control board, so that the mounting holes and locking holes correspond one by one. Then, the locking parts pass through the locking holes and mounting holes in sequence to achieve a fixed connection between the cooling fan and the mounting plate.

[0014] Optionally, the fixing plate is provided with four sets of positioning brackets for installing the cooling fan. The positioning brackets correspond to the four corners of the cooling fan, and the four sets of positioning brackets form a positioning groove for placing the cooling fan.

[0015] By adopting the above technical solution, four sets of positioning brackets are set on the outside of the four mounting holes. The positioning brackets form positioning grooves for the cooling fan, which can play a positioning role before the cooling fan is fixed, so that the installer can manually fix the cooling fan and improve the fixing efficiency.

[0016] Optionally, two adjacent sets of positioning frames in the four sets of positioning frames are slidably installed on the fixed plate, and the fixed plate is provided with slide rails for the positioning frames to slide.

[0017] By adopting the above technical solution, the slide rails set on the fixed plate allow the positioning frame to slide back and forth on the fixed plate. Before installing the cooling fan, the positioning frame is slid to the side away from the fixed through hole. At this time, the cooling fan can be placed from the side of the cabinet door of the electrical control cabinet or along the length of the electrical control cabinet. Finally, the cooling fan is positioned and clamped by the two sets of sliding positioning frames.

[0018] Optionally, a limiting block for limiting the positioning frame is provided at one end of the slide rail facing the axis of the fixed through hole.

[0019] By adopting the above technical solution, the setting of the limiting block can limit the sliding distance of the slide rail positioning frame, so that after the positioning frame and the limiting block abut, the positioning frame and the cooling fan correspond to each other.

[0020] Optionally, the positioning frame is provided with an arc-shaped sleeve for clamping the locking member on the side facing the cooling fan, and the inner wall of the arc-shaped sleeve is provided with a friction pad.

[0021] By adopting the above technical solution, the arc-shaped sleeve can clamp the locking component, and the locking component and the friction pad abut against each other, reducing the probability of the locking component moving around and improving the stability of the cooling fan on the fixed plate.

[0022] Optionally, the electrical control cabinet may also be provided with a guide duct for guiding air on the side of the fixed plate away from the cooling fan.

[0023] By adopting the above technical solution, the setting of the air duct can guide the air blown out by the cooling fan, so that the area on both control boards can be blown by the air.

[0024] Optionally, a dust cover is provided on the outside of the electrical control cabinet, and the dust cover corresponds to the ventilation hole.

[0025] By adopting the above technical solution, the dust cover can effectively prevent dust from entering the electrical control cabinet and reduce the impact of external dust on electrical components.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. This application, through the setting of a heat dissipation device, can directly cool down the power control board and drive control board, alleviate the heat accumulation in the electrical control cabinet, and reduce the probability of the two control boards burning at high temperature;

[0028] 2. This application, through the setting of the positioning bracket, can achieve a positioning effect for the installation of the cooling fan, thereby improving the installation efficiency of the cooling fan;

[0029] 3. The arc-shaped sleeve in this application can guide the locking component, improve the insertion efficiency of the locking component, and at the same time, the friction pad can reduce the probability of the locking component moving around, ensuring the stability of the cooling fan after it is fixed.

[0035] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0036] This application discloses a quay container crane drive with a heat dissipation device.

[0037] Reference Figure 1 The quay container crane drive includes an electrical control cabinet 1, a power control board 2 and a drive control board 3 located on one side inside the electrical control cabinet 1, a power failure protector 4, and a heat dissipation device 5. The electrical control cabinet 1 is generally rectangular, with two control boards installed parallel to each other at the bottom of the electrical control cabinet 1, and the power failure protector 4 located on the top side of the electrical control cabinet 1.

[0038] Reference Figure 1 and Figure 2 The heat dissipation device 5 includes a first mounting plate 51 and a second mounting plate 52 respectively disposed on opposite side walls of the electrical control cabinet 1, a fixing plate 53 connecting the two mounting plates, and a cooling fan 54 fixedly mounted on the fixing plate 53. The fixing plate 53 has a fixing through hole 531 penetrating both end faces, and the cooling fan 54 is fixed on the side of the fixing plate 53 away from the two control plates, with the output port of the cooling fan 54 facing the control plate.

[0039] Both the first mounting plate 51 and the second mounting plate 52 are rectangular plates arranged along the length of the electrical control cabinet 1. Both mounting plates are fixed with screws. The second mounting plate 52 is an L-shaped plate, which can press the power cord to the side away from the door of the electrical control cabinet 1. The two mounting plates and the control board are set accordingly to reduce the impact of the power cord on the gas passage between the control board and the top of the electrical control cabinet 1.

[0040] The fixing plate 53 is a Z-shaped metal plate. One end of the fixing plate 53 is insulated and fixed to the first mounting plate 51, and the other end is fixed to the second mounting plate 52 by screws.

[0041] To improve the airflow rate inside the electrical control cabinet 1, ventilation holes 11 and heat dissipation holes 12 are provided at the top and bottom of the electrical control cabinet 1, respectively. When the cooling fan 54 is started, a negative pressure is formed in the inner cavity of the electrical control cabinet 1 on the side away from the fixed plate 53, so that outside air enters the electrical control cabinet 1 through the ventilation holes 11; the gas is transported to the control board through the fixed through hole 531, the temperature of the gas rises after passing through the control board, and finally returns to the outside through the heat dissipation holes 12.

[0042] The mounting plate 53 also has a guide duct 13 on the side facing the two control boards to guide airflow. The guide duct 13 is fixed to the inner wall of the electrical control cabinet 1 with screws. The guide duct 13 guides air to the surface of the two control boards, further improving the heat dissipation effect.

[0043] Since the air in the electrical control cabinet 1 flows from top to bottom, a dust cover 14 corresponding to the ventilation hole 11 is fixed on the outer top of the electrical control cabinet 1. The dust cover 14 is fixed by screws or other means. The dust cover 14 can reduce the amount of dust from the outside entering the electrical control cabinet 1 along the ventilation hole 11, thereby protecting the electrical components inside the electrical control cabinet 1.

[0044] The cooling fan 54 has the same structure as existing fans. In this embodiment, the cooling fan 54 is driven by a motor, and its power supply comes from a backup power port inside the driver. The inner diameter of the fixing through hole 531 is adapted to the size of the output port of the cooling fan 54.

[0045] Reference Figure 2 and Figure 3The fixing plate 53 has multiple mounting holes 532 on the outside of the fixing through hole 531, and the mounting holes 532 penetrate both end faces of the fixing plate 53. The mounting holes 532 are spaced circumferentially along the axis of the fixing through hole 531. The cooling fan 54 is provided with locking holes 541 for fixing, and locking elements 55, which are screws, are arranged at the locking holes 541. The number of mounting holes 532 is set according to the number of locking holes 541. When installing the cooling fan 54, the locking holes 541 of the cooling fan 54 are first arranged to correspond with the mounting holes 532 of the fixing plate 53, and then the cooling fan 54 and the fixing plate 53 are fixed by screws. In this embodiment, the cooling fan 54 is rectangular in shape, and locking holes 541 are provided at each of its four corners, with the mounting holes 532 and locking holes 541 corresponding one-to-one.

[0046] The mounting plate 53 is also provided with four sets of positioning brackets 56 corresponding to the mounting holes 532 and for placing the cooling fan 54. The positioning brackets 56 are located on the side of the mounting holes 532 away from the fixing through holes 531, and all positioning brackets 56 are L-shaped brackets. The L-shaped slots of the positioning brackets 56 all face the fixing through holes 531. The four sets of positioning brackets 56 form positioning slots 561 for the cooling fan 54. Through the positioning slots 561, the cooling fan 54 can be positioned before fixed connection, improving the assembly efficiency of the cooling fan 54.

[0047] There are two scenarios for fixing the cooling fan 54 to the mounting plate 53. The first scenario is that the electrical control cabinet 1 is placed vertically, and the cooling fan 54 is located on the side of the mounting plate 53 away from the control board. When installing the cooling fan 54, it is necessary to insert the cooling fan 54 into the positioning slot 561 from top to bottom. The second scenario is that the electrical control cabinet 1 is placed horizontally. When installing the cooling fan 54, it is necessary to insert the cooling fan 54 into the positioning slot 561 from the horizontal direction.

[0048] Reference Figure 3 and Figure 4 Both methods require installers to align the cooling fan in advance. To facilitate the direct insertion of the cooling fan 54 into the positioning slot 561, two adjacent positioning frames 56 of the four sets of positioning frames 56 slide in conjunction with the fixing plate 53. The discharge direction of these two sets of positioning frames 56 is consistent with the arrangement direction of the two control plates. The positioning frame 56 slides along the length of the fixing plate 53, and a slide rail 533 that slides in conjunction with the positioning frame 56 is welded and fixed on the fixing plate 53. The slide rail 533 has a T-shaped cross-section, and the positioning frame 56 has a T-shaped groove 562 that mates with the slide rail 533. A limit block 534 is provided at the end of the slide rail 533 near the fixing through hole 531, which limits the sliding distance of the positioning frame 56.

[0049] Before installing the cooling fan 54, first move the positioning bracket 56 to the side away from the fixing through hole 531, then insert the cooling fan 54 into the positioning slot 561, and then move the last two sets of positioning brackets 56 toward the cooling fan 54. The four sets of positioning brackets 56 will achieve the effect of positioning and clamping the cooling fan 54.

[0050] The positioning bracket 56 also integrally provides an arc-shaped sleeve 563 on the side facing the fixing through hole 531. The arc-shaped sleeve 563 has a certain elastic deformation capability. The axis of the arc-shaped sleeve 563 is parallel to the axis of the fixing through hole 531. The arc-shaped sleeve 563 and the locking hole 541 are coaxially corresponding, and the arc of the arc-shaped sleeve 563 is greater than 180 degrees, so that the arc-shaped sleeve 563 can guide the locking member 55. The inner wall of the arc-shaped sleeve 563 is also glued with a friction pad 564 for abutting against the locking member 55. The friction pad 564 increases the friction force when the locking member 55 rotates, thereby reducing the probability of the locking member 55 shifting after it is fixed.

[0051] The implementation principle of a quay container crane driver with a heat dissipation device in this application embodiment is as follows: the cooling fan 54 is positioned on the fixed plate 53 by four sets of positioning brackets 56, and then the cooling fan 54 and the fixed plate 53 are fixedly connected by locking parts 55; when the driver starts to work, the cooling fan 54 also starts synchronously, and the cooling fan 54 blows air to dissipate heat on the two control boards, so that the temperature of the cooling fan 54 is always within the normal working temperature range, reducing the probability of the control boards burning due to high temperature.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
