Description

Technical Field

[0001] The present application relates to the technical field of engineering machinery, and in particular to a chain blocker and engineering machinery. Background Art

[0002] In the underground fully-mechanized mining face of a coal mine, the scraper chain of the scraper conveyor forms a closed operating system through the head sprocket, upper chain track, tail sprocket and lower chain track, which is responsible for the transportation of coal. The normal operation of the equipment requires the chain to be moderately tensioned to avoid the chain being too tight or too loose. When the scraper chain is too loose, it will affect the meshing between the chain and the sprocket, and in severe cases will cause accidents such as chain stacking, chain jumping, and chain breaking. When the scraper is running, the chain needs to be cut and pre-tightened regularly because the chain is stretched and deformed by tension. The existing methods are generally hydraulic chain tightening and gate disc chain tightening. Regardless of the chain tightening method, an important device is indispensable, that is, the chain blocker. The chain blocker is used to anchor the chain and is an essential tool for daily maintenance such as chain tension adjustment. When in use, the chain blocker is required to be firmly and stably combined with the scraper conveyor chute, and no loosening is allowed, so that the scraper chain can be effectively braked. In addition, the chain blocker is also required to have a simple structure, light weight, and be easy to operate underground.

[0003] In the prior art, a chain tightener and a chain tightening hook are usually used to tighten the scraper chain. The chain tightening hook is used to hook the upper scraper chain and then start the scraper conveyor in reverse. Under the pulling action of the chain tightening hook, the part of the upper scraper chain between the head sprocket and the chain tightening hook is in a relaxed state. Thereafter, the chain tightener is used to brake the scraper conveyor, and the relaxed part of the upper scraper chain is untied and tensioned. When the chain tightener and the chain tightening hook are used to tighten the scraper chain, one end of the chain tightening hook is hooked into the hole of the side plate of the head frame, and the other end of the chain tightening hook is hooked into the ring chain of the upper scraper chain. At the moment of starting the scraper conveyor, the chain tightening hook is instantly tightened, and at this time, the chain tightening hook is very easy to be unhooked, resulting in a safety accident.

[0038] Refer to the following Figures 1 to 6 Some embodiments provided according to the present application are described.

[0039] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a chain blocker 10 proposed according to an embodiment of the present application includes two chain assemblies 110 and a baffle assembly 120. Specifically, the chain assembly 110 includes a chain plate 112 and a rib plate 114. A notch 116 is provided on one side of the chain plate 112. The notch 116 is used to insert the scraper chain 230.

After the chain assembly 110 is installed, put the baffle assembly 120 between the two chain assemblies 110, and the limiter 132 limits the width direction of the chain assembly 110. At this time, the chain plate 112 in the chain assembly 110 limits the movement of the front and rear vertical rings, and the chain tightening and chain cutting operations can be completed. Through the chain blocker 10 provided by this embodiment, the chain blocker 10 limits the movement of the chain when tightening the chain, which can avoid the scraper from being subjected to additional force. It has a simple structure, light weight, reliable operation, and is easy to install and disassemble. It can be widely used in the chain tightening operation of the side double-chain scraper and the transfer machine.

[0041] In some embodiments, the chain blocker 10 may further include a transition groove middle plate 140, which is detachably connected to the clamping chain assembly 110.

By providing the inclined surface 180 on the upper surface of the chain plate 112, and the inclined surface 180 corresponds to the wing plate inclined surface 240, when the chain tightening operation is required, the protrusion 210 on the chain plate 112 in the chain assembly 110 is placed in the corresponding groove 190 of the transition groove middle plate 140, the chain assembly 110 can be pushed outward and the U-shaped groove on the chain plate 112 is inserted into the flat ring of the scraper chain 230, thereby limiting the movement of the front and rear vertical rings.

[0052] like Figures 1 to 6 As shown, the chain blocker 10 according to a specific embodiment of the present application specifically includes a chain assembly 110, a baffle assembly 120 and connecting bolts. The chain assembly 110 is symmetrically placed on both sides of the baffle assembly 120, and the connecting bolts connect the chain assembly 110 and the baffle assembly 120 together. When in use, the connecting bolts need to be removed, and the long strip protrusion on the chain plate 112 in the chain assembly 110 is placed into the corresponding groove 190 of the transition groove middle plate 140, and the chain assembly 110 is pushed outward and the U-shaped groove on the chain plate 112 passes through the flat ring of the scraper chain 230, at which time the two vertical rings connected to the flat ring are restricted. After the chain assembly 110 is installed, the baffle assembly 120 is placed between the two chain assemblies 110, ensuring that the chain plate 112 on the chain assembly 110 is between the two limiting plates 134 of the baffle assembly 120, and the baffle assembly 120 has a width-direction limiting effect on the chain assembly 110. After the chain is tightened, the baffle assembly 120 and the chain assembly 110 are removed, and the two are connected with bolts and then placed in a fixed place for storage.
