Description

Technical Field

[0001] The invention relates to the technical field of screen installation, and in particular to a non-destructive installation process for a mine screening machine screen. Background Art

[0002] Vibration screening equipment is one of the most critical mechanical equipment in the ore mining and processing industry. It is an indispensable and important component of the entire production line. It uses the vibration of the screen to separate particles of different sizes, thereby achieving ore screening. Vibration screening equipment is specially designed for screening materials in quarries, and can also be used for product classification in coal preparation, ore dressing, building materials, electricity and chemical industries.

[0003] Since the mine stones are generally hard and have large particle sizes, the vibration screen is subjected to a large impact during the screening process, and the screen is easily damaged or loses its original function, so the screen needs to be replaced frequently. The original vibration screen structure is that a plurality of parallel beams are fixed on the vibration frame, and a plurality of brackets are fixedly connected to the beams. A fixed specification of screen is fixedly installed on the top of the bracket, and a rubber strip is provided between the bracket and the screen. Therefore, only the specified type of screen can be used for equipment maintenance. If there is no suitable screen to replace when it is damaged, it will greatly affect the production efficiency and even the production of the entire production line. In the event of technical upgrades and equipment modifications, the progress of the work will be greatly affected.

[0004] If you need to replace the screen of different sizes, the existing installation solution requires re-welding the bracket to the screen frame, and the bracket must match the size of the screen to be installed before installing the screen. After multiple replacements, the structural strength of the side plate is seriously damaged, which brings safety hazards to the use of the equipment and affects the service life of the equipment. Summary of the invention

[0005] The purpose of the present invention is to overcome the problems in the prior art and provide a non-destructive installation process for a mine screening machine screen.

[0006] The present invention provides a non-destructive installation process for a mine screening machine screen. Figure 1-2 -3-4-5 includes the following steps:

[0007] A plurality of clamping strips are clamped on the crossbeam, and the distance between two adjacent clamping strips matches the width of the screen to be installed;

[0008] Each connecting strip is provided with a frame;

[0009] The rubber strip is clamped in the groove on the frame;

[0010] Two adjacent frames are clamped at the two ends of the same screen;

[0011] If there are brackets and rubber strips on the beam, remove them.

[0012] Preferably, the material of each of the clamping strips and the rubber strip is polyurethane.

[0013] Preferably, a T-shaped groove is provided on the upper surface of the snap-fit ​​strip, and the T-shaped groove is snap-fitted with the cross-sectional shape of the frame.

[0014] Preferably, the frame is an aluminum alloy frame, and the frame spans across a plurality of beams.

[0015] Preferably, the lower end of the rubber strip is engaged with a groove provided on the frame, and the upper surface of the rubber strip is provided with two rows of limiting structures, each row of limiting structures includes a plurality of limiting columns, and the limiting columns on two adjacent frames are engaged with the limiting groove provided on the lower surface of the screen.

[0016] Compared with the prior art, the beneficial effects of the present invention are: the non-destructive installation process of the mining screening machinery screen of the present invention can quickly install screens of various specifications, and does not require re-welding of the bracket, and will not damage the structural strength of the original bracket. The skeleton is perpendicular to the direction of the original beam, which increases the friction between the two, avoids relative sliding between the skeleton and the beam, and ensures stable operation of the equipment.

[0024] The specific implementation of the present invention is described in detail below, but it should be understood that the protection scope of the present invention is not limited by the specific implementation. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] The present invention provides a non-destructive installation process for a mine screening machine screen, such as Figure 1-2 -3-4-5 includes the following steps:

[0026] A plurality of clamping strips 4 are clamped on the crossbeam 1, and the distance between two adjacent clamping strips 4 matches the width of the screen 6 to be installed;

[0027] Each of the clamping strips 4 is clamped with a frame 5;

[0028] The rubber strip 7 is clamped in the groove on the frame 5;

[0029] Two adjacent frames 5 are clamped at both ends of the same screen 6;

[0030] If there are brackets 2 and rubber strips 3 on the crossbeam 1, remove the brackets 2 and rubber strips 3.

[0031] Preferably, the material of each of the clamping strips 4 and the rubber strip 7 is polyurethane.

[0032] The clamping strips 4 and the rubber strips 7 made of polyurethane material can ensure that the mounting frame 5 can be tightly combined with the cross beam 1 , absorb high-frequency vibrations on the cross beam 1 , and prevent high-frequency collisions between the frame 5 and the cross beam 1 .

[0033] Preferably, if Figure 2-3 The upper surface of the clamping strip 4 is provided with a T-shaped groove, and the T-shaped groove is clamped and matched with the cross-sectional shape of the frame 5 .

[0034] The purpose is to prevent the clamping strip 4 and the frame 5 from loosening.

[0035] Preferably, if Figure 3-4 -5 The skeleton 5 is an aluminum alloy skeleton, and the skeleton 5 spans across a plurality of beams 1.

[0036] The skeleton 5 is perpendicular to the original crossbeam 1, which increases the friction between the two, avoids relative sliding between the skeleton 5 and the crossbeam 1, and ensures normal and stable operation.

[0037] Preferably, if Figure 4-5 The lower end of the rubber strip 7 is engaged with the groove provided on the frame 5, and the upper surface of the rubber strip 7 is provided with two rows of limiting structures, each row of limiting structures includes a plurality of limiting columns 8, and the limiting columns on two adjacent frames 5 are engaged with the limiting groove provided on the lower surface of the screen 6.
