Description

Technical Field

[0001] This utility model relates to the field of coal transportation technology, and in particular to an oblong bidirectional hydraulic gate for coal bunkers. Background Technology

[0002] A gate is a device similar to a sluice gate. In coal transportation, it is necessary to close the outlet of the coal bunker through a gate. Existing technologies include unidirectional electric gates, bidirectional electric gates, and manual gates. The patent with publication number CN2016212299U discloses an oblong bidirectional gate, which is directly driven by a hydraulic cylinder and has reasonable assembly clearance. The gate slides on the roller, eliminating the common problems of jamming and stuck during opening and closing caused by corrosion and broken teeth in various gates. In addition, through the through-type cylindrical structure, the main cylinder of the gate is not the same as the two side cavities of the gate body, eliminating the coal storage point inside the gate. The unique rounded corner structure inside avoids the coal blockage problem. Furthermore, the small gap between the gate and the track makes it difficult for coal slag to enter the side cavity (i.e., the storage chamber). The small amount of coal accumulated inside the side cavity can also be easily removed at any time through the cleaning hole at the bottom of the side wall.

[0003] During the use of this gate, in order to ensure the recovery of the gate plate, there is still a gap for coal slag to pass through. Although an inclined side wall is set, the coal that falls into the side cavity is not easy to sweep away and is difficult to clean thoroughly. Summary of the Invention

[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide an oblong bidirectional hydraulic gate for coal bunkers.

[0005] This utility model provides an oblong bidirectional hydraulic shut-off gate for coal bunkers, comprising a main cylinder composed of a lower cylinder and an upper cylinder. The main cylinder has shut-off gate bodies on both sides along a first direction. Each shut-off gate body has a gate plate that can be inserted into the main cylinder. The shut-off gate body also has a slag storage mechanism, which includes:

[0006] The guiding component includes a waste discharge channel located on the bottom surface inside the gate body. The top of the lower cylinder is provided with a first guide plate that extends downwards at an angle away from the main cylinder. The bottom end of the first guide plate is connected to the bottom surface inside the gate body and located on one side of the waste discharge channel. The bottom surface inside the gate body and located on the other side of the waste discharge channel is provided with a second guide plate. The second guide plate extends upwards at an angle away from the main cylinder. A slag-accumulating cavity is formed between the first guide plate and the second guide plate, which communicates with the waste discharge channel.

[0007] The second guide plate has a first connecting plate on the top side away from the main cylinder, and the top of the first connecting plate has a scraping strip that abuts against the bottom surface of the gate.

[0008] The slag storage box is detachably installed on the bottom of the gate body at the corresponding waste discharge channel position, and has a first opening at the top that connects to the waste discharge channel.

[0009] According to the technical solution provided in the embodiments of this application, the first connecting plate is provided with a downwardly recessed arc-shaped plate on the side away from the second guide plate, the arc-shaped plate is provided with a second connecting plate on the side away from the second guide plate, and the second connecting plate is provided with a scraping strip;

[0010] The bottom of the arc-shaped plate is provided with an inflow channel that connects to the middle of the second guide plate. The inflow channel is used to connect the interior of the arc-shaped plate with the slag-accumulating cavity.

[0011] According to the technical solution provided in the embodiments of this application, the lower half of the cylinder is equipped with a sealing mechanism, which is used to seal the gap between the lower half of the cylinder and the upper half of the cylinder and the gate.

[0012] According to the technical solution provided in the embodiments of this application, the sealing mechanism includes:

[0013] The upper sealing strip is located on the bottom surface of the upper half of the cylinder.

[0014] The lower drive unit is used to push the gate plate upward.

[0015] According to the technical solution provided in the embodiments of this application, the lower drive unit includes an outer edge protrusion on the top surface of the lower half cylinder. The top end of the outer edge protrusion is provided with a mounting cavity. An air bladder is provided inside the mounting cavity. The air nozzle of the air bladder extends out of the outer edge protrusion through a mounting through hole. The air nozzle is connected to the output pipe of the air source.

[0016] According to the technical solution provided in the embodiments of this application, the first guide plate consists of an inclined plate that slopes downward and an end plate located at the top of the lower half-cylinder. The end plate is provided with a connecting hole corresponding to the position of the mounting cavity. The connecting hole is provided with countersunk grooves on both sides along the radial direction of the main cylinder. An elastic pad is provided between the end plate and the lower half-cylinder. The top of the lower half-cylinder is provided with a threaded pin hole corresponding to the position of the countersunk groove.

[0017] According to the technical solution provided in the embodiments of this application, the lower drive unit includes an arc-shaped protrusion disposed on the bottom surface of the gate plate and fitting with the top surface of the lower cylinder. The end face of the arc-shaped protrusion facing the central axis of the main cylinder is provided with a guide slope. The guide slope and the top surface of the gate plate have a first included angle, and the first included angle is directed away from the central axis of the main cylinder.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] This utility model is equipped with a storage mechanism, a first guide plate, a second guide plate, and a scraping strip. The coal powder on the bottom surface of the gate is wiped and scraped off, and enters the slag storage box through the waste discharge channel. Simply removing the slag storage box allows for quick removal and cleaning of the accumulated coal, effectively improving cleaning efficiency. Furthermore, to avoid insufficient wiping, an arc-shaped plate, an inflow channel, and a scraping strip are provided to more thoroughly wipe and scrape off the coal powder, allowing the coal powder to fall from the inflow channel between the first guide plate and the second guide plate, improving cleaning efficiency and ensuring thorough cleaning.

[0020] In addition, a sealing mechanism is provided. The lower drive unit pushes the gate plate against the upper sealing strip to achieve a sealing effect. The lower drive unit can be an arc-shaped protrusion and a guide ramp. When it contacts the top surface of the lower cylinder, the gate plate is raised by the guide ramp, thereby achieving a sealing effect. Alternatively, the lower drive unit can be a combination of an air bladder and an elastic pad. Inflating the air bladder pushes the elastic pad to bulge upward, further pushing the gate plate upward, thereby achieving a sealing effect. This effectively prevents coal dust from entering the gate body and avoids the situation where dust enters the gate body and causes coal dust to contaminate and damage the connection between the hydraulic cylinder and the gate plate.

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0033] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0034] Please refer to Figure 1 This utility model provides an oblong bidirectional hydraulic gate for a coal bunker, comprising a main cylinder composed of a lower cylinder 1 and an upper cylinder 2. Gate bodies 4 are provided on both sides of the main cylinder along a first direction. A gate plate 3, insertable into the main cylinder, is provided inside the gate body 4. The first direction is... Figure 1 The left and right directions in the middle are the prior art in the patent with publication number CN2016212299U, which will not be elaborated here;

[0035] The main body 4 of the gate also has a slag storage mechanism 5, which includes:

[0036] The guiding assembly includes a waste discharge channel 57 located on the bottom surface inside the gate body 4. The top of the lower cylinder 1 is provided with a first guide plate 51 that extends downwards at an angle away from the main cylinder. The bottom end of the first guide plate 51 is connected to the bottom surface inside the gate body 4 and located on one side of the waste discharge channel 57. The bottom surface inside the gate body 4 and located on the other side of the waste discharge channel 57 is provided with a second guide plate 52. The second guide plate 52 extends upwards at an angle away from the main cylinder. A slag-accumulating cavity is formed between the first guide plate 51 and the second guide plate 52, which communicates with the waste discharge channel 57.

[0037] The top of the second guide plate 52 is provided with a first connecting plate 54 away from the main cylinder, and the top of the first connecting plate 54 is provided with a scraping strip 55 that abuts against the bottom surface of the gate plate 3.

[0038] The slag storage box 59 is detachably installed on the bottom of the gate body 4 at the position corresponding to the waste discharge channel 57, and has a first opening at the top that connects to the waste discharge channel 57.

[0039] like Figure 1 and Figure 2 As shown, when the gate 3 is pulled out of the main cylinder, some of the coal dust falls onto the first guide plate 51. The coal dust moves downwards at an angle into the waste discharge channel 57, while another portion is wiped off by the scraper strip 55 and falls onto the side of the second guide plate 52. It also moves downwards at an angle into the waste discharge channel 57 and then into the slag storage box 59, thus achieving the cleaning and collection of coal dust. Only the slag storage box 59 needs to be removed for quick cleaning. Compared to the existing technology where coal dust falls into the corners of the gate body 4, this method achieves the same result. The present application has high cleaning efficiency and thorough cleaning without dead corners; optionally, the top of the slag storage box 59 is bolted to the bottom surface of the gate body 4, and a sealing gasket 58 is provided between the slag storage box 59 and the bottom surface of the gate body 4 to improve the sealing performance and prevent the coal powder from "escaping" from the slag storage box 59 during the falling process; in addition, it should be noted that since the left and right sides of the main cylinder are semicircles, the first guide plate 51, the waste discharge channel 57 and the second guide plate 52 are all in annular state and are concentrically set with the semicircle of the main cylinder.

[0040] In some embodiments, the first connecting plate 54 is provided with a downwardly recessed arc-shaped plate 53 on the side away from the second guide plate 52, and the arc-shaped plate 53 is provided with a second connecting plate 510 on the side away from the second guide plate 52, and a scraping strip 55 is provided on the second connecting plate 510.

[0041] The bottom of the arc plate 53 is provided with an inlet channel 56 that connects to the middle of the second guide plate 52. The inlet channel 56 is used to connect the interior of the arc plate 53 with the slag cavity.

[0042] like Figure 1 and Figure 2 As shown, the scraping strip 55 on the second connecting plate 510 can perform secondary scraping on the bottom surface of the gate plate 3, further improving the wiping efficiency. After the coal powder falls off, it will be sent into the slag collection cavity along the inlet channel 56 at the bottom of the arc plate 53, and then discharged through the waste discharge channel 57, realizing two scrapings and a single slag storage box 59, thereby improving the processing efficiency of waste slag and coal powder.

[0043] In some embodiments, the lower cylinder 1 is equipped with a sealing mechanism 6, which seals the gap between the lower cylinder 1 and the upper cylinder 2 and the gate plate 3. This prevents coal dust from entering the gate body 4 and avoids damage caused by coal dust contamination at the connection between the hydraulic cylinder and the gate plate 3.

[0044] In some embodiments, the sealing mechanism 6 includes:

[0045] The upper sealing strip 610 is located on the bottom surface of the upper half-cylinder 2;

[0046] The lower drive unit is used to push the gate 3 to move upward.

[0047] The upper sealing strip 610 seals the gap between the upper cylinder 2 and the gate 3. The lower drive unit pushes the gate 3, thereby sealing the gap between the lower cylinder 1 and the gate 3. On the one hand, it can achieve an effective sealing effect. On the other hand, if there is no gap at all, the gate 3 will be stuck. Therefore, if the lower drive unit is not used, the movement gap of the gate 3 can be preserved, ensuring the stability of the horizontal movement of the gate 3.

[0048] In some embodiments, the lower drive unit includes an outer edge protrusion 61 on the top surface of the lower half cylinder 1. The top end of the outer edge protrusion 61 is provided with a mounting cavity 62. An air bladder 63 is provided inside the mounting cavity 62. The air nozzle 65 of the air bladder 63 extends out of the outer edge protrusion 61 through a mounting through hole 64. The air nozzle 65 is connected to the output pipe of the air source.

[0049] like Figure 3 As shown, by filling the airbag 63 with gas, the airbag 63 inflates. Restricted by the mounting cavity 62, the airbag 63 can only push upwards, thereby achieving the purpose of pushing the gate 3 upwards. Since the top of the left half and the top of the right half of the lower cylinder 1 are at different horizontal heights, the mounting cavity 62 is composed of arc and straight lines in the top view. The airbag 63 is inserted into it and fits into it, improving the stability of the airbag 63 during use. In addition, the connection method between the air nozzle 65 and the air source is existing technology and will not be described in detail here.

[0050] In some embodiments, the first guide plate 51 consists of an inclined plate that slopes downward and an end plate located at the top of the lower half-cylinder 1. The end plate is provided with a connecting hole 66 corresponding to the position of the mounting cavity 62. The connecting hole 66 is provided with countersunk grooves 67 on both sides of the radial direction of the main cylinder. An elastic pad 68 is provided between the end plate and the lower half-cylinder 1. The top of the lower half-cylinder 1 is provided with a threaded pin hole 69 corresponding to the position of the countersunk groove 67.

[0051] like Figure 3 As shown, the elastic pad 68 is installed by screwing through the countersunk groove 67 and the elastic pad 68 and threading it into the threaded pin hole 69. If the airbag 63 is in direct contact with the gate 3, the shape of the airbag 63 may change during the movement of the gate 3, and the airbag 63 may also detach from the mounting cavity 62. However, by adding the elastic pad 68, the direct contact between the airbag 63 and the gate 3 can be completely avoided, ensuring the stability of the airbag 63 during use.

[0052] In some embodiments, the lower drive unit includes an arc-shaped protrusion disposed on the bottom surface of the gate plate 3 and fitting with the top surface of the lower cylinder 1. The end face of the arc-shaped protrusion facing the central axis of the main cylinder is provided with a guide slope. The guide slope and the top surface of the gate plate 3 have a first included angle, which faces away from the central axis of the main cylinder.

[0053] like Figure 4 As shown, when the guide ramp comes into contact with the lower half-cylinder 1, it will drive the gate 3 to move upward. The bottom end of the arc-shaped protrusion abuts against the top surface of the lower half-cylinder 1 to achieve a sealing effect. This method has a simple structure, is easy to manufacture and process, is highly practical, and has high scalability.
