Example 1

As shown in fig. 1-4, the invention provides a wear-resistant sliding plate for a belt conveyor, which comprises a conveying belt 1 and a material guide chute 2, wherein the conveying belt 1 is slidably arranged in the material guide chute 2, and ceramic sliding plates 3 are arranged between the outer walls of two sides of the stack of the conveying belt 1 and the inner walls of two sides of the material guide chute 2.

Specifically, traditional slide adopts the polymer polyethylene slide, and this kind of slide has characteristics such as better wearability, corrosion resistance, nevertheless to the belt conveyor of long-time operation, still great degree's the wearing and tearing condition, and because this kind of slide setting is in 1 bottom of conveyer belt for the staff is difficult to know specific wearing and tearing condition, and even when changing the slide after ascertaining the wearing and tearing condition, also need demolish conveyer belt 1 and just can change, and is very inconvenient.

In this device, the adoption sets up ceramic slide 3 in 1 side of conveyer belt, only need be under the safe state of equipment shut down, lift 1 one side of conveyer belt, can observe ceramic slide 3's the concrete wearing and tearing condition, and ceramic slide 3 self wearability is far stronger than the polymer polyethylene slide, can use longer time, and ceramic slide 3 is owing to have smooth glaze, make its glaze and conveyer belt 1 contact, so the coefficient of friction between conveyer belt 1 and the ceramic slide 3 is very little because of extremely low roughness, make the slip of conveyer belt 1 more smooth and easy, and the frictional heating that the dynamic friction produced is littleer, damage to conveyer belt 1 is littleer. The conveying belt 1 is a conveying rubber belt, a feeding opening 8 is formed in the upper portion of the conveying belt, the guide chute 2 is fixed on the support and is mainly used for supporting the conveying belt 1 to run, the conveying belt 1 is enabled to form a groove-shaped structure used for containing coal materials, the guide chute 2 at least comprises two side plates, two sides of the conveying belt 1 are lapped on the two side plates of the guide chute 2, the middle portion of the conveying belt is concave downwards to form an arc shape, and the conveying belt is driven by a driving motor to advance.

Example 2

As shown in fig. 2 and 3, a fixing plate 4 is provided on the inner wall of the material guiding chute 2, and the ceramic sliding plate 3 is fixed on the fixing plate 4.

The ceramic sliding plate 3 comprises a plurality of spliced ceramic substrates 301 which are continuously spliced in four directions. The spliced ceramic substrate 301 is adhered to the fixing plate 4 through the adhesive layer 5.

Specifically, slide among the prior art when wearing and tearing transfinite, the fixing bolt 6 of slide can directly rub conveyer belt 1, when wearing and tearing fracture, the corner of slide can rub conveyer belt 1, and these problems all can lead to conveyer belt 1 damaged.

In this device, the one side of ceramic slide 3 is glaze and the contact of conveyer belt 1, and then the another side is rough surface, conveniently pastes through bonding glue film 5 and fixed plate 4 and is connected, because ceramic slide 3 bonds with fixed plate 4, so when 3 wearing and tearing of ceramic slide surpass the limit, also can not cause the scratch to conveyer belt 1. And ceramic slide 3 is connected the concatenation by a plurality of concatenation ceramic substrate 301 all around and forms in this device, on the one hand be convenient for transport and installation, on the other hand when certain department of ceramic slide 3 damages the back, only need to change the concatenation ceramic substrate 301 of this department can, saved cost of maintenance. In addition, the ceramic sliding plate 3 and the inner wall of the guide chute 2 are indirectly connected through the fixing plate 4, so that the bonding strength can be improved through the treatment of the fixing plate 4, for example, the surface of the fixing plate 4 is subjected to galling treatment, and the surface of the guide chute 2 is obviously and directly treated inconveniently.

Example 3

As shown in fig. 2, 3 and 4, the joined ceramic substrate 301 is provided with a connecting taper hole 302, and the connecting taper hole 302 is narrowed from a side far from the fixing plate 4 to a side near the fixing plate 4. The connecting piece 303 is embedded in the connecting hole, and the connecting piece 303 is fixedly connected with the fixing plate 4. The fixing plate 4 is a steel plate, and the connecting piece 303 penetrates through the connecting hole and is welded with the steel plate.

In the device, the spliced ceramic substrate is basically connected with the fixed plate 4 through the connecting piece 303, and when the adhesive layer 5 fails, the connecting piece 303 can effectively limit the spliced ceramic substrate 301 from moving relative to the fixed plate 4. The connecting taper hole 302 has a guiding function for facilitating the rapid insertion of the connecting member 303, and the connecting taper hole 302 has a function for sinking the connecting member 303 into the ceramic substrate, so that the connecting member 303 does not contact with the conveyor belt 1 to scratch the conveyor belt 1 when the ceramic substrate is worn because the connecting member 303 sinks into the connecting taper hole 302. Secondly, when fixed plate 4 was the steel sheet, can directly carry out spot welding to the steel sheet region that connects taper hole 302 and correspond, the residue that the welding rod hot melt formed this moment is attached to the steel sheet to the embedding forms connecting piece 303 in connecting taper hole 302 promptly, very convenient will splice ceramic substrate 301 and steel sheet fixed connection.

Example 4

As shown in fig. 3, the fixing plate 4 includes a plurality of splicing fixing substrates 401 that are continuously spliced in four directions, and the splicing fixing substrates 401 are fixedly connected to the material guide chute 2 by bolts 6.

In this device, fixed plate 4 is constituteed through the continuous concatenation in a plurality of concatenation PMKD 401 four sides, can be respectively the transportation, the equipment and the change of fixed plate 4, and the four corners position that each concatenation PMKD 401 is close to baffle box 2 one side all is connected with bolt 6, and bolt 6 runs through the cell wall of baffle box 2 to realize bolt 6 fixed connection between through nut and the baffle box 2.

Example 5

As shown in fig. 1, a plurality of conveying rollers 7 are disposed at the bottom of the conveying belt 1, and the distance between the top ends of the two side walls of the material guide chute 2 is greater than the distance between the bottom ends thereof. The ceramic sliding plate 3 is made of aluminum oxide wear-resistant ceramic.

In this device, the lateral wall and the 3 sliding contact of ceramic slide of conveyer belt 1, conveyer belt 1's bottom is passed through transfer roller 7 and is supported, and a plurality of transfer rollers 7 set up along conveyer belt 1's direction of motion interval for support conveyer belt 1. The guide chute 2 has a large top end interval and a small bottom end interval, so that the conveying belt 1 in the guide chute forms the same open shape, and can better receive coal falling from the feeding port 8 at the upper part. The aluminum oxide wear-resistant ceramic has good wear resistance.

The working principle of the device is as follows:

the abrasion of the sliding plate is reduced by adopting the ceramic sliding plate 3; the ceramic sliding plate 3 is arranged between the conveying belt 1 and the side wall of the material guide groove 2, so that the abrasion condition can be conveniently checked and replaced at any time; the ceramic sliding plate 3 is composed of a plurality of spliced ceramic substrates 301, and is convenient to replace when a certain part is abraded.
