Description

Technical Field

[0001] This invention relates to the field of crane cooling, and more particularly to a cooling water discharge device for bridge cranes. Background Technology

[0002] Bridge cranes are lifting equipment widely used in factories, warehouses, logistics centers and other places. They are mainly used for horizontal movement of heavy objects. They consist of a bridge frame, crane trolley, operating system and other components. They can move freely in the factory building and have high work efficiency and flexibility.

[0003] In the prior art, such as Chinese Publication No. CN101219763A, the invention discloses a water cooling device for the external brake of a grab bucket excavator. The device is characterized by comprising a cooling chamber disposed within the wire rope drum brake, a water inlet chamber communicating with the cooling chamber, and a water outlet pipe. The water inlet chamber is disposed within one hub of the drum, and one end of the water outlet pipe is installed within the other hub of the drum. Rotary joints are installed at the water inlet end of the water inlet chamber and the water outlet end of the water outlet pipe. This invention can promptly remove the heat generated by friction between the external brake assembly and the brake, preventing slippage due to heat accumulation, thus eliminating safety hazards, enabling the braking system to operate continuously, improving production efficiency, and simultaneously preventing wear on the friction band of the external brake assembly, thereby extending the service life of the friction band.

[0004] In summary, during the operation of a crane, especially when the motor or other mechanical equipment operates for extended periods, the heat generated needs to be dissipated through a cooling system. If the equipment temperature is too high, it may lead to mechanical failure or overload damage. Some existing cooling methods involve installing water pipes in the areas of the crane that generate heat. Water carries away the heat through the pipes, and after use, the water is cooled and then discharged back into the pipes for further cooling. While the cooled water carries away heat through contact with the used water, over time, the cooling water contains many impurities, which can cause pipe blockage and reduce heat exchange efficiency. Furthermore, the contact between the cooled water and the used water is not thorough enough when the used water is cooled, resulting in a less than ideal cooling effect and reducing the practicality of the cooling device. Summary of the Invention

[0005] This invention provides a cooling water drainage device for a bridge crane. When using the cooling device, this invention filters impurities in the cooling water to prevent impurities from clogging the pipes and affecting the cooling effect. It also prevents impurities from clogging the filter screen, keeping the filter screen unobstructed and avoiding blockage. The device has a better cooling effect, improves the practicality of the device, and the cooling water can be recycled multiple times, reducing resource waste.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a cooling water discharge device for a bridge crane, the device comprising:

[0007] Cooling tank and cooling pipes;

[0008] The support frame is slidably disposed on the inner wall of the cooling box, and a filter screen is provided on the inner wall of the support frame. The support frame can slide on the inner wall of the cooling box and supports the filter screen. The filter screen filters impurities in the cooling water to prevent impurities from clogging the pipes and affecting the cooling effect.

[0009] Multiple base plates are fixedly installed on the inner wall of the support frame, and a first telescopic rod is fixedly installed on one side of each of the multiple base plates, and the multiple base plates support the multiple first telescopic rods.

[0010] Multiple second telescopic rods are movably embedded in the inner walls of multiple first telescopic rods, and one side of each of the multiple second telescopic rods is respectively located on the side of the support frame near the four corners. The multiple second telescopic rods can slide on the inner walls of the multiple first telescopic rods.

[0011] Two pressure plates are disposed on one side of the support frame, and a connecting rod is fixedly disposed at the center of the opposite side of the two pressure plates. When one pressure plate rotates, the other pressure plate is driven to rotate through the connecting rod.

[0012] As a further improvement of the present invention: A return spring is fixedly installed on the inner wall of each of the first telescopic rods; a rotating rod is fixedly installed on one side of one of the pressure plates; multiple transmission plates are fixedly sleeved on the outer surface of the rotating rod; a connecting box is movably sleeved on the outer surface of the rotating rod; a water outlet pipe is provided on one side of the cooling box; a valve is installed on the outer surface of the water outlet pipe; a cover plate is provided on one side of the cooling box; the multiple return springs have elasticity and generate a reverse force when compressed; when the two pressure plates are in a horizontal state, the reverse force of the multiple return springs pushes the multiple second telescopic rods upward. The support frame is lifted further upwards, and as the two pressure plates rotate back and forth, the support frame moves up and down, further causing the filter screen to vibrate, effectively reducing the deposition of impurities on the filter screen and keeping the filter screen unobstructed. When the cooling water circulates, the cooling water flows through the inside of the connecting box. At this time, the cooling water hits multiple transmission plates, and the rotating rod can rotate. The circulating cooling water drives multiple transmission plates to rotate, which in turn drives one of the pressure plates to rotate. Through the connecting rod, it drives the other pressure plate to rotate. When the two pressure plates rotate, they will squeeze the support frame downwards, which will further cause multiple second telescopic rods to slide into the inside of multiple first telescopic rods.

[0013] As a further improvement of the present invention: a first semicircular plate is fixedly installed on the inner wall at the center of the cooling pipe, and a second semicircular plate is fixedly embedded on the inner wall near both sides of the cooling pipe. Cooling water is discharged into the interior of the cooling box through the delivery pipe. When the cooling water is inside the cooling box, it passes through one of the second semicircular plates, then through the first semicircular plate, and finally through the other second semicircular plate before being discharged. When the cooling water flows, it will fully contact the outer surface of the multiple hollow pipes, thereby driving the heat of the water inside the multiple hollow pipes.

[0014] As a further improvement of the present invention: multiple hollow tubes are fixedly embedded in the inner walls of the first semicircular plate and the two second semicircular plates, and a first separation tube is fixedly provided on one side of the cooling box. Water that carries away heat flows into the interior of the first separation tube through the water inlet pipe and is further discharged into the interior of the multiple hollow tubes.

[0015] As a further improvement of the present invention: a water inlet pipe is installed on one side of the first separation pipe, and a second separation pipe is fixedly installed on the side of the cooling box away from the first separation pipe. A drain pipe is installed on the outer surface of the second separation pipe. The cooling pipe of the crane is connected through the water inlet pipe. Water that carries away heat flows into the interior of the first separation pipe through the water inlet pipe. The cooled water is discharged into the interior of the second separation pipe and discharged through the drain pipe. One side of the second separation pipe is arc-shaped, which can reduce the impact force of water on the second separation pipe.

[0016] As a further improvement of the present invention: baffles are fixedly embedded in the inner walls of the first separation tube and the second separation tube, and the two baffles are fixedly sleeved on the outer surface of the plurality of hollow tubes. The two baffles prevent the cooling water inside the cooling box from flowing into the interior of the second separation tube and the first separation tube.

[0017] As a further improvement of the present invention: a first connecting pipe is installed on the outer surface of the cooling tank near the water inlet pipe, and a delivery pump is installed at one end of the first connecting pipe. The cooling water inside the cooling tank is discharged into the inside of the second connecting pipe through the first connecting pipe under the action of the delivery pump.

[0018] As a further improvement of the present invention: the output end of the delivery pump is provided with a second connecting pipe, one side of the second connecting pipe is fixedly disposed on one side of the connecting box, and a third connecting pipe is installed on one side of the connecting box. When the delivery pump is turned on, the cooling water inside the cooling box is discharged into the second connecting pipe through the first connecting pipe under the action of the delivery pump, and further drives multiple transmission plates to rotate through the connecting box, and is discharged into the cooling box through the third connecting pipe.

[0019] As a further improvement of the present invention: one end of the third connecting pipe is installed on one side of the cooling box, and one end of the water outlet pipe is equipped with a conveying pipe. The cooling water for cooling and filtration is discharged into the interior of the conveying pipe through the water outlet pipe for use.

[0020] As a further improvement of the present invention: one end of the conveying pipe is installed on the outer surface of the cooling box near the first separation pipe, and the cooling water is discharged into the interior of the cooling box through the conveying pipe.

[0021] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0022] 1. In this invention, when using the cooling device, cooling water is poured into the cooling box by opening the cover. During cooling, the cooling water passes through a filter screen, which removes impurities. Multiple second telescopic rods can slide along the inner walls of multiple first telescopic rods. During cooling water circulation, the cooling water flows through the inside of the connecting box, impacting multiple transmission plates. The rotating rod can then rotate, and the circulating cooling water drives the multiple transmission plates to rotate. This further causes the rotating rod to drive one of the pressure plates to rotate, which in turn drives the other pressure plate to rotate via the connecting rod. As the two pressure plates rotate, they press down on the support frame, causing the multiple second telescopic rods to slide into the interior of the multiple first telescopic rods. At this point, one side of the multiple second telescopic rods and multiple... One side of the inner wall of each of the first telescopic rods is pressed against multiple return springs. These return springs have elasticity and generate a counterforce when compressed. When the two pressure plates are horizontal, the counterforce of the return springs pushes the second telescopic rods upward, further lifting the support frame. As the two pressure plates rotate back and forth, the support frame moves up and down, further vibrating the filter screen. This effectively reduces the deposition of impurities on the filter screen, keeping it clear. When the valve is opened, the cooling water inside the cooling tank is discharged through the outlet pipe. This filters impurities in the cooling water during the use of the cooling device, preventing impurities from clogging the pipes and affecting the cooling effect. It also prevents impurities from clogging the filter screen, keeping it clear and avoiding blockage.

[0023] 2. In this invention, cooling water is supplied to the crane via an inlet pipe connected to the crane's cooling pipe. The heated water flows through the inlet pipe into the first separation pipe, and further into multiple hollow tubes. The cooling water then flows through a delivery pipe into the cooling tank. Inside the cooling tank, the cooling water passes through one of the second semicircular plates, then the first semicircular plate, and finally exits through the other second semicircular plate. During the flow of the cooling water, it fully contacts the outer surfaces of the multiple hollow tubes, absorbing the heat from the water inside. The cooled water then flows into the second separation pipe and is discharged through a drain pipe. One side of the second separation pipe is arc-shaped, which reduces the impact force of the water on the second separation pipe, thus improving the cooling effect and enhancing the practicality of the device.

[0024] 3. In this invention, when using the device, the cooling water inside the cooling tank is discharged into the delivery pipe through a valve, and then further discharged into the cooling tank. At this time, the delivery pump is turned on, and the cooling water inside the cooling tank is discharged into the second connecting pipe through the first connecting pipe under the action of the delivery pump. It is then discharged into the cooling tank through the third connecting pipe via multiple transmission plates driven by the connecting box, where it is cooled and filtered. Finally, it is discharged into the delivery pipe through the outlet pipe for recycling. Thus, when using the device, the cooling water can be recycled multiple times, reducing resource waste.

[0035] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0036] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0037] See also Figures 1 to 9This embodiment provides a cooling water drainage device for a bridge crane. The device includes a cooling tank 1 and cooling pipes 3; a support frame 2, slidably disposed on the inner wall of the cooling tank 1, and a filter screen 201 disposed on the inner wall of the support frame 2; multiple base plates 202, fixedly disposed on the inner wall of the support frame 2, and a first telescopic rod 203 fixedly disposed on one side of each of the multiple base plates 202; multiple second telescopic rods 204, movably embedded in the inner wall of the multiple first telescopic rods 203, and one side of each of the multiple second telescopic rods 204 is disposed on one side of the support frame 2 near the four corners; and two pressure plates. 212, a connecting rod 208 is fixedly installed at the center of the opposite side of the two pressure plates 212, and a return spring 205 is fixedly installed on the inner wall of the multiple first telescopic rods 203. A rotating rod 207 is fixedly installed on one side of one of the pressure plates 212. Multiple transmission plates 213 are fixedly sleeved on the outer surface of the rotating rod 207. A connecting box 206 is movably sleeved on the outer surface of the rotating rod 207. A water outlet pipe 209 is provided on one side of the cooling box 1. A valve 210 is installed on the outer surface of the water outlet pipe 209. A cover plate 211 is provided on one side of the cooling box 1.

[0038] In use, cooling water is poured into the cooling tank 1 by opening the cover 211. During cooling, the cooling water passes through the filter screen 201, which removes impurities from the cooling water. Multiple second telescopic rods 204 can slide along the inner walls of multiple first telescopic rods 203. During cooling water circulation, the cooling water flows through the connecting box 206, impacting multiple transmission plates 213. The rotating rod 207 can then rotate. The circulating cooling water drives the multiple transmission plates 213 to rotate, further causing the rotating rod 207 to rotate one of the pressure plates 212. This rotation, via the connecting rod 208, drives the other pressure plate 212 to rotate. As the two pressure plates 212 rotate, they press downwards against the support frame 2, further causing the multiple second telescopic rods... Rod 204 slides into the interior of multiple first telescopic rods 203. At this time, one side of multiple second telescopic rods 204 and one side of the inner wall of multiple first telescopic rods 203 respectively squeeze multiple return springs 205. Multiple return springs 205 have elasticity and will generate a reverse force when squeezed. When the two pressure plates 212 are in a horizontal state, the reverse force of multiple return springs 205 pushes multiple second telescopic rods 204 upward, further lifting the support frame 2. As the two pressure plates 212 rotate back and forth, the support frame 2 moves up and down, further causing the filter screen 201 to vibrate, effectively reducing the deposition of impurities in the filter screen 201 and keeping the filter screen 201 unobstructed. The valve 210 is opened, and the cooling water inside the cooling box 1 is discharged through the water outlet pipe 209.

[0039] Please see Figures 1 to 9In one embodiment, a first semicircular plate 301 is fixedly installed on the inner wall at the center of the cooling pipe 3, and a second semicircular plate 308 is fixedly embedded on the inner wall near both sides of the cooling pipe 3. Cooling water is discharged into the interior of the cooling box 1 through the conveying pipe 404. When the cooling water is inside the cooling box 1, it passes through one of the second semicircular plates 308, then through the first semicircular plate 301, and finally through the other second semicircular plate 308 before being discharged. When the cooling water flows, it will fully contact the outer surface of the multiple hollow pipes 302, thereby generating heat from the water inside the multiple hollow pipes 302.

[0040] Please see Figures 1 to 9 In one embodiment, a plurality of hollow tubes 302 are fixedly embedded in the inner walls of the first semicircular plate 301 and the two second semicircular plates 308. A first separation tube 304 is fixedly provided on one side of the cooling box 1. Water that carries away heat flows through the water inlet pipe 305 into the interior of the first separation tube 304 and is further discharged into the interior of the plurality of hollow tubes 302.

[0041] Please see Figures 1 to 9 In one embodiment, a water inlet pipe 305 is installed on one side of the first separation pipe 304, and a second separation pipe 306 is fixedly installed on the side of the cooling tank 1 away from the first separation pipe 304. A drain pipe 307 is installed on the outer surface of the second separation pipe 306. The cooling pipe of the crane is connected through the water inlet pipe 305. Water that carries away heat flows into the interior of the first separation pipe 304 through the water inlet pipe 305. The cooled water is discharged into the interior of the second separation pipe 306 and discharged through the drain pipe 307. One side of the second separation pipe 306 is arc-shaped, which can reduce the impact force of water on the second separation pipe 306.

[0042] Please see Figures 1 to 9 In one embodiment, baffles 303 are fixedly embedded in the inner walls of the first separation tube 304 and the second separation tube 306. The two baffles 303 are fixedly sleeved on the outer surface of the plurality of hollow tubes 302. The two baffles 303 prevent the cooling water inside the cooling box 1 from flowing into the interior of the second separation tube 306 and the first separation tube 304.

[0043] Please see Figures 1 to 9 In one embodiment, a first connecting pipe 4 is installed on the outer surface of the cooling tank 1 near the water inlet pipe 305. A delivery pump 401 is installed at one end of the first connecting pipe 4. The cooling water inside the cooling tank 1 is discharged into the second connecting pipe 402 through the first connecting pipe 4 and under the action of the delivery pump 401.

[0044] Please see Figures 1 to 9In one embodiment, the output end of the delivery pump 401 is provided with a second connecting pipe 402. One side of the second connecting pipe 402 is fixedly disposed on one side of the connecting box 206. A third connecting pipe 403 is installed on one side of the connecting box 206. When the switch of the delivery pump 401 is turned on, the cooling water inside the cooling box 1 is discharged into the second connecting pipe 402 through the first connecting pipe 4 and under the action of the delivery pump 401. The water then drives multiple transmission plates 213 to rotate through the connecting box 206 and is discharged into the cooling box 1 through the third connecting pipe 403.

[0045] Please see Figures 1 to 9 In one embodiment, one end of the third connecting pipe 403 is installed on one side of the cooling box 1, and one end of the water outlet pipe 209 is equipped with a conveying pipe 404. Cooling and filtering water is discharged into the interior of the conveying pipe 404 through the water outlet pipe 209 for use.

[0046] Please see Figures 1 to 9 In one embodiment, one end of the delivery pipe 404 is installed on the outer surface of the cooling tank 1 near the first separation pipe 304, and cooling water is discharged into the interior of the cooling tank 1 through the delivery pipe 404.

[0047] Working principle: When using the cooling device, cooling water is poured into the cooling tank 1 by opening the cover plate 211. During cooling, the cooling water passes through the filter screen 201, which removes impurities from the cooling water. Multiple second telescopic rods 204 can slide along the inner walls of multiple first telescopic rods 203. During cooling water circulation, the cooling water flows through the connecting box 206, impacting multiple transmission plates 213. The rotating rod 207 can rotate, and the circulating cooling water drives the multiple transmission plates 213 to rotate. This further causes the rotating rod 207 to drive one of the pressure plates 212 to rotate, which in turn drives the other pressure plate 212 to rotate via the connecting rod 208. As the two pressure plates 212 rotate, they press down on the support frame 2, further causing the multiple second telescopic rods 204 to slide into the interior of the multiple first telescopic rods 203. At this time, the multiple second telescopic rods 204... The sides and the inner walls of the multiple first telescopic rods 203 respectively squeeze the multiple return springs 205. The multiple return springs 205 have elasticity and will generate a reverse force when squeezed. When the two pressure plates 212 are in a horizontal state, the reverse force of the multiple return springs 205 pushes the multiple second telescopic rods 204 upward, further lifting the support frame 2. As the two pressure plates 212 rotate back and forth, the support frame 2 moves up and down, further causing the filter screen 201 to vibrate, effectively reducing the deposition of impurities in the filter screen 201 and keeping the filter screen 201 unobstructed. When the valve 210 is opened, the cooling water inside the cooling box 1 is discharged through the water outlet pipe 209. Thus, when using the cooling device, impurities in the cooling water are filtered to prevent impurities from clogging the pipes and affecting the cooling effect. It can also prevent impurities from clogging the filter screen 201, keeping the filter screen 201 unobstructed and avoiding clogging.

[0048] Cooling water is supplied to the crane via an inlet pipe 305 connected to the crane's cooling pipes. The water, carrying away heat, flows through the inlet pipe 305 into the first separation pipe 304, and then into the multiple hollow pipes 302. At this point, the cooling water is discharged into the cooling tank 1 through the delivery pipe 404. Inside the cooling tank 1, the cooling water passes through one of the second semicircular plates 308, then through the first semicircular plate 301, and finally through the other second semicircular plate 308 before being discharged. During the flow of the cooling water, it fully contacts the outer surfaces of the multiple hollow pipes 302, carrying away the heat of the water inside the multiple hollow pipes 302. The cooled water is then discharged into the second separation pipe 306 and discharged through the drain pipe 307. One side of the second separation pipe 306 is arc-shaped, which can reduce the impact force of the water on the second separation pipe 306. Therefore, when using the cooling device, the cooling effect is better, improving the practicality of the device.

[0049] When using the device, the cooling water inside the cooling tank 1 is discharged into the delivery pipe 404 through valve 210, and then further discharged into the cooling tank 1. At this time, the delivery pump 401 is turned on, and the cooling water inside the cooling tank 1 is discharged into the second connection pipe 402 through the first connecting pipe 4 under the action of the delivery pump 401. It is then further discharged into the cooling tank 1 through the third connecting pipe 403 to drive multiple transmission plates 213 to rotate, and then discharged into the cooling tank 1 through the third connecting pipe 403 for cooling and filtration. Finally, it is discharged into the delivery pipe 404 through the outlet pipe 209 for recycling. Thus, when using the device, the cooling water can be recycled multiple times, reducing resource waste.

[0050] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments that can be applied to other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
