Description

Technical Field

[0002] Crane refers to a multi-action lifting machine that can lift heavy objects vertically and move them horizontally within a certain range. It is also called overhead crane, overhead crane, or crane.

[0003] Some lifting equipment has the working characteristic of intermittent movement, that is, the corresponding mechanisms of taking materials, moving, unloading, etc. work alternately in one working cycle. The development and use of cranes in the market are becoming more and more extensive;

[0004] However, after long-term use, a lot of dust is often adsorbed on the observation window of the cab of the crane. Therefore, most of the existing observation windows of the cab are equipped with a rubber scraper with a fan-shaped motion track. When the rubber scraper is scraping the dust on the observation window, the friction between the rubber scraper and the observation window is very large, so the contact part between the rubber scraper and the observation window is easy to deform, so there are often traces of dust on the observation window. At the same time, in addition to the fan-shaped area, there are many places on the observation window that are not scraped, and the friction will also generate a lot of noise.

At the same time, the material of the knocking head 17 is rubber, but it is filled with hard blocks inside, so when the knocking head 17 contacts the glass, the sound emitted is also very small. The outer side surface of the arc-shaped rubber friction plate 12 is also evenly provided with a plurality of water spray ports 41 that can spray water toward the observation window from top to bottom. The outer peripheral surface of the inner rotating rod 14 is evenly provided with a plurality of first auxiliary drive blocks 21, and the inner peripheral surface of the outer rotating cylinder 6 is evenly provided with a plurality of second auxiliary drive blocks 42 that are adapted to the first auxiliary drive blocks 21, and the second auxiliary drive block 42 is slidably connected to the inner rotating rod 14 at one end away from the outer rotating cylinder 6, wherein an arc-shaped limit groove is provided at a position corresponding to the second auxiliary drive block 42 on the outer peripheral surface of the inner rotating rod 14, so that the second auxiliary drive block 42 can be The end of the driving block 42 away from the outer rotating cylinder 6 is slidably connected in the arc-shaped limiting groove, and the third spring 22 is fixedly connected to the opposite surfaces of the adjacent first auxiliary driving block 21 and the second auxiliary driving block 42 on a horizontal plane, wherein four second auxiliary driving blocks 42 are fixedly connected to the middle part of the inner circumference of each outer rotating cylinder 6, and at the same time, four first auxiliary driving blocks 21 are also fixedly connected to the outer circumference of the inner rotating rod 14 at the position corresponding to the horizontal level of each second auxiliary driving block 42. Therefore, when the inner rotating rod 14 rotates, through the setting of the third spring 22, the first auxiliary driving block 21 can push the second auxiliary driving block 42 to rotate with it, and the rear side of the driving barrel 4 is provided with a scraping component whose side can be attached to the observation window.

[0032] By arranging the inner rotating rod 14, the outer rotating cylinder 6, the arc-shaped rubber friction plate 12 and the water spray port 41, when the arc-shaped rubber friction plate 12 is wiping dust on the observation window, the water spray port 41 can spray water on the wiping area, thereby being able to better wipe the dust off the observation window, and by arranging the scraping component, the water stains mixed with dust remaining on the observation window can be scraped off, thereby being able to make the surface of the observation window cleaner.

[0033] By means of the first auxiliary driving block 21, the third spring 22 and the second auxiliary driving block 42, the inner rotating rod 14 can drive the outer rotating cylinder 6 to rotate, wherein when the arc-shaped rubber friction plate 12 encounters the bird droppings adhered to the observation window, the resistance encountered by the arc-shaped rubber friction plate 12 will increase, so that the third spring 22 will be further compressed, so that when the arc-shaped rubber friction plate 12 passes over the bird droppings, the arc-shaped rubber friction plate 12 at this time does not wipe off the bird droppings, and the next arc-shaped rubber friction plate 12 in contact with the bird droppings will accelerate toward the observation window because the third spring 22 will be reset at this time, so that by means of the setting of the striking head 17, when the arc-shaped rubber friction plate 12 accelerates toward the observation window, the striking head 17 will impact the bird droppings, thereby causing the bird droppings to fall off the observation window, and the water sprayed from the water spray port 41 will make the bird droppings wet, so that the bird droppings will fall off more easily.

[0034] A slide 2 is provided at the top of the right side of the driver's cab body 1, and a limiting slide groove 29 is provided on the inner bottom surface of the slide 2. The driving cylinder 3 and the driving barrel 4 are both slidably connected in the slide 2, and the left end of the driving cylinder 3 is fixedly connected to the screw slide. Therefore, when the screw slide is working, it can move the driving cylinder 3 forward and backward, and the driving cylinder 3 will prompt the driving barrel 4 to move with it. A dividing component is fixedly connected to the inner bottom surface of the limiting slide groove 29, and a limiting cylinder 30 with one end slidably connected to the limiting slide groove 29 is fixedly connected to the lower surface of the driving barrel 4.

Figure 7 At the same time, the driving barrel 4 will move to the right. Finally, when the limiting cylinder 30 passes over the block 10, the block 10 will be prompted to return to its initial position through the setting of the fourth spring 28. Then, when the driving barrel 4 moves backward, the surface of the limiting cylinder 30 will fit against the right side of the dividing guide plate 9 until the limiting cylinder 30 moves to the rearmost end of the limiting groove 29 because there is space between the rearmost end of the dividing guide plate 9 and the limiting groove 29 that can prompt the limiting cylinder 30 to move to the left. Then the limiting cylinder 30 will detach from the dividing guide plate 9 and return to its initial position.

[0036] The arc-shaped rubber friction plate 12 is fixedly connected to an arc-shaped auxiliary fixing block 13 at one end close to the striking head 17, and the arc-shaped auxiliary fixing block 13 is fixedly connected to the outer rotating cylinder 6 at one end away from the arc-shaped rubber friction plate 12, and the arc-shaped auxiliary fixing block 13 is fixedly connected to an arc-shaped guide block 20 at one end inserted into the water spout 41 at one end close to the arc-shaped rubber friction plate 12. The inner wall of the arc-shaped rubber friction plate 12 is evenly fixedly connected to a plurality of first springs 19 at one end of which are all arranged on the outer rotating cylinder 6 from top to bottom. Therefore, when the arc-shaped rubber friction plate 12 is squeezed, the arc-shaped rubber friction plate 12 will be deformed, and at the same time, because the inner rotating rod 14 rotates counterclockwise as shown in FIG. Figure 2 , which can cause the arc-shaped rubber friction plate 12 to rotate with it, but friction will appear between the arc-shaped rubber friction plate 12 and the observation window, so sliding will occur between the water spray port 41 and the arc-shaped guide block 20, so that the water spray port 41 will be opened, and the water in the arc-shaped rubber friction plate 12 will be sprayed onto the observation window.

[0037] The outer circumference of the outer rotating cylinder 6 is evenly provided with a plurality of water inlets, wherein the number and position of the water inlets are one-to-one corresponding to the arc-shaped rubber friction plate 12, and an auxiliary fixing ring 25 is fixedly connected to one end of the water inlet close to the inner rotating rod 14, a first tension spring 24 is fixedly connected to the side of the auxiliary fixing ring 25 away from the inner rotating rod 14, and an auxiliary sealing plate 23 is fixedly connected to one end of the first tension spring 24 away from the auxiliary fixing ring 25, and the auxiliary sealing plate 23 can slide in the water inlet, and a plurality of first connecting ports 16 are evenly provided on the outer circumference of the inner rotating rod 14, and through the setting of the first connecting ports 16, it can It can promote the inner rotating rod 14 to be connected with the outer rotating cylinder 6. At the same time, when the squeezed arc-shaped rubber friction plate 12 returns to its initial state, the setting of the first spring 19 can promote the arc-shaped rubber friction plate 12 to return to its initial state, and the auxiliary sealing plate 23 will be pushed open by water, and then water flows into the arc-shaped rubber friction plate 12. When the water in the arc-shaped rubber friction plate 12 is filled, the auxiliary sealing plate 23 will return to its initial position through the setting of the first tension spring 24, so that the next time the arc-shaped rubber friction plate 12 is squeezed again, the water therein can also be sprayed out from the water spray port 41.

[0038] The top end of the inner rotating rod 14 extends into the driving barrel 4, and a bearing is provided between the inner rotating rod 14 and the driving barrel 4. The top end of the inner rotating rod 14 is fixedly connected to the first bevel gear 31. The inner front side and the inner rear side of the driving barrel 4 are fixedly connected to auxiliary fixing plates 35, and the opposite ends of the two auxiliary fixing plates 35 are fixedly connected to auxiliary stabilizing cylinders 34. The inner circumference of the auxiliary stabilizing cylinder 34 is rotatably connected to a driving shaft 36. One end of the driving shaft 36 close to the first bevel gear 31 is fixedly connected to a second bevel gear 32 with an outer circumferential surface toothed on the first bevel gear 31. The driving shaft 36 is away from the first bevel gear 31. One end of the bevel gear 31 is slidably connected to a rectangular driving rod 33, and one end of the rectangular driving rod 33 away from the driving shaft 36 is fixed to the rotating shaft of the driving motor. Therefore, when the driving motor is working, it can drive the rectangular driving rod 33 to rotate, and the rectangular driving rod 33 can drive the driving shaft 36 to rotate. The driving shaft 36 can prompt the first bevel gear 31 to rotate through the setting of the second bevel gear 32, and the first bevel gear 31 can prompt the inner rotating rod 14 to rotate. When looking down at the first bevel gear 31, its rotation direction is counterclockwise.

[0039] The top of the inner rotating rod 14 is provided with a water supply component capable of supplying water to the inner rotating rod 14, and the water supply component is connected to the water pump in the water storage tank, and the water supply component includes a conveying ring plate 38 rotatably connected to the top of the inner rotating rod 14, wherein a sealing ring is provided at the connection between the conveying ring plate 38 and the inner rotating rod 14, and a second communication port capable of promoting the inner rotating rod 14 to communicate with the conveying ring plate 38 is opened on the outer circumference of the inner rotating rod 14, and a plurality of auxiliary fixing columns 4 are evenly fixed to the lower surface of the conveying ring plate 38 0, the bottom end of the auxiliary fixing column 40 is fixedly connected to the driving barrel 4, and the outer peripheral surface of the conveying ring plate 38 is fixedly connected with a water pipe 39 connected with the conveying ring plate 38, and the end of the water pipe 39 away from the conveying ring plate 38 is connected with the water pump, so when the inner rotating rod 14 rotates, the conveying ring plate 38 will not rotate. At the same time, when the water pump is working, water can be conveyed into the conveying ring plate 38 through the water pipe 39, so that the water in the conveying ring plate 38 flows into the inner rotating rod 14 through the second connecting port.

[0040] The scraping component includes a scraping fixing rod 5 fixed to the driving barrel 4, and a rubber scraper 7 is bonded to the side of the scraping fixing rod 5 close to the observation window. When water is sprayed on the observation window, when the rubber scraper 7 scrapes the observation window, the water can greatly reduce the friction between the rubber scraper 7 and the observation window, thereby greatly reducing the noise generated and at the same time greatly reducing the occurrence of cracks or breakages in the rubber scraper 7.

[0041] A collecting groove plate 8 is provided at the bottom end of the right side of the driver's cab body 1 near the observation window, and a filter screen 11 is provided at one end of the right side of the driver's cab body 1 near the collecting groove plate 8, and a delivery pipe with one end wrapped with the filter screen 11 is provided in the driver's cab body 1, and the end of the delivery pipe away from the filter screen 11 is fixedly connected to the water tank, so the water sprayed on the observation window will flow into the collecting groove plate 8, and then after being filtered by the filter screen 11, it will finally flow into the water tank, and at the same time, after rainwater flows into the collecting groove plate 8, it will also be filtered by the filter screen 11 and flow into the water tank through the delivery pipe, wherein when the water in the water tank reaches the maximum storage capacity, a large amount of water will be stored in the collecting groove plate 8, so it is necessary for personnel to manually open the water plug to drain the water in the collecting groove plate 8. A water plug is threadedly connected to the front side of the collecting groove plate 8.

[0042] In summary, when the crane cab is in use, the personnel can use the control box to make the driving motor, the screw slide and the water pump work together, so that when the screw slide works, it can prompt the driving barrel 4 to move forward and backward, and when the driving motor works, it can prompt the inner rotating rod 14 to rotate, and the inner rotating rod 14 can rotate with the outer rotating cylinder 6, so as to prompt the arc-shaped rubber friction plate 12 to wipe the dust on the surface of the observation window. The screw slide prompts the driving barrel 4 to move forward and backward relatively slowly, so that a part on the observation window will be wiped by the arc-shaped rubber friction plate 12 for many times, and when the arc-shaped rubber friction plate 12 is wiping, the water spray port 41 will spray water on the observation window, so that the arc-shaped rubber friction plate 12 can better wipe the dust off the observation window;

[0043] By means of the first auxiliary driving block 21, the third spring 22 and the second auxiliary driving block 42, the inner rotating rod 14 can drive the outer rotating cylinder 6 to rotate, wherein when the arc-shaped rubber friction plate 12 encounters the bird droppings adhered to the observation window, the resistance encountered by the arc-shaped rubber friction plate 12 will increase, so that the third spring 22 will be further compressed, so that when the arc-shaped rubber friction plate 12 passes over the bird droppings, the arc-shaped rubber friction plate 12 at this time does not wipe off the bird droppings, and the next arc-shaped rubber friction plate 12 in contact with the bird droppings will accelerate to rush toward the observation window because the third spring 22 will be reset at this time, so that by means of the setting of the striking head 17, when the arc-shaped rubber friction plate 12 accelerates to rush toward the observation window, the striking head 17 will impact the bird droppings, thereby causing the bird droppings to fall off the observation window, and the water sprayed from the water spray port 41 will make the bird droppings wet, so that the bird droppings will fall off more easily;

[0044] When the rubber scraper 7 scrapes the observation window, the water can greatly reduce the friction between the rubber scraper 7 and the observation window, thereby greatly reducing the noise generated, and at the same time can greatly reduce the occurrence of cracks or breaks in the rubber scraper 7;

[0045] When the surface of the limiting cylinder 30 is attached to the right side of the dividing guide plate 9, the arc-shaped rubber friction plate 12 and the rubber scraper 7 have been separated from the observation window. Therefore, when the arc-shaped rubber friction plate 12 and the rubber scraper 7 move backward with the driving barrel 4, they will not contact the observation window. When the limiting cylinder 30 moves to the rearmost end of the limiting slide groove 29, the limiting cylinder 30 will be separated from the dividing guide plate 9, so that the arc-shaped rubber friction plate 12 and the rubber scraper 7 will return to their initial positions.
