Problems solved by technology

If the wear of the chain presser exceeds the standard, it will cause the scraper chain to pop out of the chute, so that the conveyor cannot work normally
In order to reduce the cost of replacing the new chain presser, it is necessary to repair the worn chain presser. The existing method of repairing the chain presser is to use the method of direct surfacing welding, but the chain presser itself is arc-shaped, and the The high temperature often makes the chain presser seriously deformed, so that the repaired chain presser cannot be installed and used again

Embodiment 1

[0031] figure 1 The schematic diagram of the surfacing welding mold of the chain presser provided by Embodiment 1 of the present invention is combined below figure 1 The embodiments of the present invention will be described in detail.

[0032] Embodiment 1 of the present invention provides a surfacing mold for a chain presser, which includes a fixing plate 1 arranged vertically, and a positioning hole 3 for fixing the chain presser 2 is formed on the fixing plate 1, and the number of positioning holes 3 is at least three , The shape of the connection line of each positioning hole 3 matches the shape of the chain presser 2 . In actual use, the number of positioning holes 3 may not be limited to three.

[0033] The existing chain presser 2 itself has positioning installation holes, and the fixed plate 1 in this embodiment can match the number of positioning holes 3 on the chain presser surfacing mold according to the number of positioning installation holes that the chain pre...

Embodiment 2

[0036] figure 2 The schematic diagram of the overlay welding mold of the chain presser provided by the second embodiment of the present invention, the difference between the second embodiment of the present invention and the first embodiment is that the mold also includes a chassis support 9, which is fixedly arranged on the fixed plate 1 Below, support the fixed plate 1 . Such as figure 2 shown.

[0037] The underframe bracket plays a role of fixing and supporting the fixed plate, and there are various forms of the underframe bracket. The underframe bracket used in the embodiment of the present invention is as follows figure 2 As shown, the specific form is that at least two I-shaped brackets are fixed under the plate. This design is simple in structure and reliable in function. The actual needs of this embodiment can be met.

Embodiment 3

[0039] image 3 It is a schematic diagram of the surfacing welding mold of the chain presser provided by the third embodiment of the present invention. This embodiment is based on any of the above-mentioned embodiments. Preferably, the surfacing mold of the chain presser also includes a plurality of ribs 4, and the ribs 4 are vertically arranged and fixedly connected to one side of the fixed plate 1 vertically. , that is, one side of the chain presser 2 needs to be fixed, and the upper edges of the plurality of ribs 4 match the shape of the chain presser 2 .

[0040] In use, the arc-shaped area of ​​the chain presser wears the most severely, and the surfacing welding is mainly to repair the arc-shaped area of ​​the chain presser 2, and a plurality of rib plates 4 are set, which are vertically fixed on one side of the fixed plate 1, for The arc-shaped area of ​​the chain presser 2 is supported, the deformation space of the chain presser in the surfacing welding process is limi...

Abstract

The invention discloses a chain presser build-up welding mould and a build-up welding method. The chain presser build-up welding mould comprises a fixing board, wherein the fixing board is vertically arranged; positioning holes used for fixing a chain presser are formed on the fixing board; the positioning holes are at least three in number; and the connection shape of the three positioning holes are matched with the shape of the chain presser. According to the chain presser build-up welding mould and the build-up welding method provided by the invention, the positioning holes are formed on the fixing board to fix the chain presser, and the connection shape of the positioning holes are matched with the shape of the chain presser, so that the positioning effect is good, the structural characteristics of the chain presser per se are fully utilized, the chain presser can be effectively prevented from being deformed during the build-up process, and the chain presser restored by build-up welding can be normally mounted and used.

Description

technical field [0001] The invention relates to mechanical welding technology, in particular to a surfacing welding mold and a surfacing welding method for a chain presser. Background technique [0002] The scraper conveyor is the only transportation equipment in the longwall coal mining face at present. It mainly includes the nose, the middle part and the tail. The nose and the tail are used to provide power, and the middle part is used to carry and transport materials. Specifically: the power source is provided by the power unit of the machine head, and the movement of the middle part is driven by the scraper chain. The scraper chain is arranged in the chute of the middle part, and the tail is used to provide the power for the return of the middle part. Because the nose and tail are higher than the middle part, the connection between the nose and the middle part is arc-shaped, and the connection between the tail and the middle part is also arc-shaped, in order to prevent t...
