Description

Technical Field

[0001] This utility model belongs to the field of coal mine equipment transfer machines, specifically relating to a fully enclosed top plate for a transfer machine. Background Technology

[0002] Transfer conveyors are crucial transportation equipment in underground coal mining faces, primarily used to transfer coal mined by coal mining machines to scraper conveyors or other transport equipment. In practical applications, transfer conveyors typically require the installation of a "roof plate" (also known as a roof guard or cover plate), whose core function is to ensure equipment operation safety, improve operational efficiency, and extend equipment lifespan. During coal transportation and crushing, a large amount of dust is generated, affecting the underground environment. A fully enclosed roof plate can effectively reduce dust impact and ensure a safe working environment underground. In existing technologies, a small tongue plate extends from the roof plate to seal the gap between two sections of the conveyor belt. However, due to the horizontal and vertical bending of the conveyor belt, existing structures cannot perfectly follow the bending to seal the gap between the roof plates. Patent CN223117600U discloses a retractable protective device for a transfer conveyor, including a telescopic cover. Patent CN206035489U discloses a fully enclosed telescopic protective device for a scraper transfer conveyor. However, these are all telescopic covering structures, with one end fixed and the other sliding, inevitably creating gaps, which cannot solve the problem of gaps between the closed top plates; moreover, telescopic movement requires power and cannot achieve adaptive adjustment. What is needed is a structure that can perfectly adapt to the bending changes of the central channel and the gaps between the closed channel cover plates without changing the structure of the top plate.

[0016] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings and specific embodiments. Figure 1-3As shown, a fully enclosed top plate for a transfer machine includes several top plates 3 fixedly installed above the central trough 1 of the transfer machine, with gaps between adjacent top plates 3 above the central trough 1. Connecting plates 4 are installed in the gaps between adjacent top plates 3; each end of the connecting plate 4 is respectively installed on two adjacent top plates 3; the connecting plate 4 is made of a flexible wear-resistant material. The flexible wear-resistant material can be an existing material, such as rubber. The connecting plate 4 and its two ends and corresponding top plates 3 can be fixedly connected, relying solely on the deformation of the flexible wear-resistant material to adapt to changes in the gaps between adjacent central troughs 1. Alternatively, at least one end of the connecting plate 4 can be slidably connected to the corresponding top plate 3, adapting to the deformation of the trough in the length direction through sliding, and using the flexible wear-resistant material to achieve changes in the gap shape caused by deformations such as vertical bending of the trough. When the position of two adjacent central troughs 1 changes slightly or undergoes bending deformation, the distance and shape of the gaps between their corresponding top plates 3 will also change. In this utility model, a connecting plate 4 is provided on the gap between adjacent top plates 3. The connecting plate 4 has a certain elastic deformation or flexible deformation capability, and can stretch and bend when the tank is bent horizontally or vertically, so as to ensure that the tank can close the gap between the top plates 3 when it is in different postures.

[0017] Furthermore, at least one end of the connecting plate 4 is slidably connected to the corresponding end cap 3; during the sliding process, the connecting plate 4 always covers the gap between the two end caps 3. The sliding connection can employ existing common methods, such as using a groove and slider structure, to adaptively change the gap between the two end caps 3. Using a sliding connection reduces the deformation of the flexible plate, allowing for longer service life and reducing damage; it also accommodates gaps with larger deformation.

[0018] Preferably, the sliding end of the connecting plate 4 has several elongated holes 4 arranged side by side along its width direction; the end of the top plate 3 near the connecting plate 4 has mounting holes corresponding to the elongated holes 4; a sliding connector 5 is disposed through the elongated holes 4 and the mounting holes; the upper and lower ends of the sliding connector 5 are respectively provided with limiting structures to prevent itself from dislodging from the elongated holes 4 and the mounting holes. Here, the length direction of the connecting plate 4 is consistent with the length direction of the central groove 1 and the top plate 3, and the width direction is consistent with the width direction of the central groove 1 and the top plate 3. The sliding connector 5 can be a pin, bolt, or other parts. The limiting structure can be a nut, bolt, U-shaped clip, or other common structures. The mounting hole is preferably a round hole, but it can also be an elongated hole 4, as long as it ensures that the connecting plate 4 and the top plate 3 are slidably connected.

[0019] Furthermore, the connecting plate 4 is disposed on the upper surface of the capping plate 3; a pressure plate 6 is disposed on the upper surface of the sliding end of the connecting plate 4; the sliding connector 5 passes through the pressure plate 6, the connecting plate 4, and the capping plate 3 sequentially from top to bottom; a through hole is disposed on the pressure plate 6 corresponding to the sliding connector 5. The sliding connector 5 can be a bolt, and the mounting hole on the capping plate 3 can be a through hole or a threaded hole. The limiting structure at the upper end of the bolt can be its own nut, disposed on the upper surface of the pressure plate 6. A nut can be disposed at the lower end of the bolt protruding from the capping plate 3 as a limiting structure at the lower end. The tightness of the limiting mechanism needs not to affect the sliding between the connecting plate 4 and the capping plate 3. Because the connecting plate 4 is made of flexible material, and the elongated hole 4 on it also has a certain degree of elasticity, if the pressure plate 6 is not provided, then under high force or after long-term use, wear will increase, and the sliding connector 5 may come out of the elongated hole 4. The present invention provides a pressure plate 6 on the connecting plate 4 to prevent the flexible material connecting plate 4 from coming out of the bolt. Preferably, the pressure plate 6 is a single long strip, through which all the sliding connectors 5 pass. Of course, the pressure plate 6 can also be divided into multiple pieces, with each pressure plate 6 corresponding to one or more of the sliding connectors 5.

[0020] Furthermore, the width of the elongated hole 4 on the connecting plate 4 is greater than the diameter of the mounting hole on the top plate 3 and the through hole on the pressure plate 6. In this case, the sliding end of the connecting plate 4 can also have a certain displacement in the width direction, thereby adapting to the size and shape of the gap.

[0021] Preferably, one end of the connecting plate 4 is detachably fixedly connected to the top plate 3, and the other end is slidably connected to the top plate 3 on the other side; the connecting plate 4 is made of rubber. The connecting plate 4 is configured with a detachable connection structure, for example, fixedly connected by bolts. The connecting plate 4 can be easily replaced after wear or damage. At this time, a row of elongated holes 4 is provided on one end of the connecting plate 4, and a row of through holes is provided on the other end; threaded holes can be provided on the top plate 3 on the side fixedly connected to the connecting plate 4 at the positions corresponding to the through holes.

[0022] In this invention, two side plates 2 are fixedly installed on both sides of each central groove 1, for example, by welding; the two ends of the top plate 3 in the width direction are respectively fixed to the corresponding side plates 2. These are existing technologies. There is also a gap between two adjacent side plates 2 on the same side, which can be connected using the connecting plate 4 of this invention.

[0023] In specific implementation: when the two adjacent middle troughs 1 undergo changes in position and shape such as horizontal or vertical bending, the connecting plate 4 can slide to elongate or deform to bend, so as to ensure that the trough can close the gap of the top plate 3 in different postures.

[0024] The technical features of the embodiments described above can be combined in any way, and as long as there is no contradiction in the combination of these technical features, they should all be considered within the scope of this specification. Without departing from the overall concept of this utility model, any equivalent substitutions or modifications made to the technical solution of this utility model, as well as any changes and improvements, should also be considered within the protection scope of this utility model.
