Description

Technical Field

[0001] The utility model relates to the technical field of belt conveyor devices, in particular to a clamping self-adjusting single-side coal dropping return belt cleaner. Background Art

[0002] During peak production periods, coal often spills from the edge of the belts onto the bottom belt at the transfer point where the two belts overlap vertically. This can easily cause coal blocks on the bottom belt to be pulled into the tail drum, leading to major accidents such as damage to the rubber lagging of the tail drum and damage to the foundation of the tail drum.

[0003] In the existing technology, a V-shaped return belt cleaner is installed at the tail of the belt. The coal on the return belt is swept to both sides by the cleaner. However, in actual production, the floating coal on the pedestrian side is easily cleaned. However, on the non-pedestrian side, because the belt frame edge is only 0.5 meters away from the road side, the floating coal on the narrow belt side cannot be cleaned in time when the machine is running. The staff must clean it uniformly after the machine is shut down. If the machine is running for a long time, the accumulation of floating coal will easily cause it to rub against the belt and rollers, causing belt damage. Summary of the Invention

[0004] In order to solve the problems that the current V-shaped return belt cleaner sweeps the coal to both sides, and the floating coal on the non-pedestrian side cannot be cleaned in time, resulting in friction between the floating coal and the belt and rollers, causing belt damage, the utility model provides a clamping self-adjusting single-sided coal-dropping return belt cleaner.

[0005] The utility model is implemented by the following technical solutions:

[0006] The self-adjusting single-sided coal-dropping return belt cleaner with a clamp includes a pair of clamps mounted on the relative positions of the belt frame, and a main frame movable in the vertical direction is installed between the two clamps. The main frame includes a vertically fixed belt cleaner fixing rod and a scraper frame. One end of the belt cleaner fixing rod is installed on the clamp on the non-pedestrian side, and the other end of the belt cleaner fixing rod is fixed to the middle of the scraper frame. One end of the scraper frame is installed on the clamp on the pedestrian side, and a scraper is pressed on the scraper frame.

[0007] During implementation, it includes a pair of clamps mounted on the relative positions of the belt frame. The belt frame is made of channel steel or angle steel. The clamp includes two clips clamped on both sides of the belt frame. The clips are made of 10 mm steel plates. The length of the clips is greater than the height of the belt frame. Fixing holes for installing fixing bolts are opened on the four corners of the clips. The fixing bolts are M16×120 bolts. The aperture of the fixing holes is 18 mm. The fixing bolts are installed on the upper and lower sides of the belt frame. An oblong hole is opened on the clip facing the belt side. The length of the oblong hole is 10 cm. Mounting bolts are installed in the oblong hole. The mounting bolts are M16×100 bolts. The mounting bolts are fixed by double nuts to prevent the mounting bolts from slipping when the main frame moves up and down; pads are fixed on the four corners of the clip with oblong holes facing the belt frame, which are used to lean against the belt frame to leave space for the mounting bolts to move between the belt frame and the clips. The thickness of the pads is greater than the thickness of the heads of the mounting bolts to prevent the belt frame and the film from clamping the bolt heads of the mounting bolts.

[0008] A main frame that moves in the vertical direction is installed between the two armrests. The main frame includes a vertically fixed belt cleaner fixing rod and a scraper frame. One end of the belt cleaner fixing rod is installed on the armrest on the non-pedestrian side. One end of the belt cleaner fixing rod is provided with a fixing rod bending portion, and a round hole is opened on the fixing rod bending portion. The mounting bolts pass through the oblong hole and the round hole in sequence to movably install the belt cleaner fixing rod on the armrest; the angle between the fixing rod bending portion and the rod body is 135°.

[0009] The other end of the belt cleaner fixing rod is fixed to the middle part of the scraper frame, and a reinforcing rib is welded at the connection between the scraper frame and the belt cleaner fixing rod; one end of the scraper frame is installed on the pedestrian side arm, and a scraper frame bending part is provided at one end of the scraper frame, and a round hole is opened on the scraper frame bending part. The mounting bolts pass through the oblong hole and the round hole in turn to movably install the scraper frame on the arm; the angle between the scraper frame bending part and the scraper frame body is 135°.

[0010] A scraper is pressed onto the scraper frame. The scraper is made of a polyurethane belt. A pressure strip arranged parallel to the scraper frame is installed on the scraper frame through bolts. A pressure strip is clamped between the pressure strip and the scraper frame.

[0011] When in use, install the clamps at the same position on both sides of the belt rack. Specifically, place the clips on the inner and outer sides of one belt rack respectively, and use fixing bolts to install the two clips on the belt rack. After the installation is completed, fix the clips on the other side of the belt rack, and the installation of the two clamps is completed.

[0012] Tighten the bolts so that the pressure strip clamps the scraper between the pressure strip and the scraper frame, install the scraper on the scraper frame so that the edge of the scraper is parallel to the scraper frame, adjust the position of the mounting bolts in the oblong hole, install the bent part of the fixing rod on the clamp, and install the bent part of the scraper frame on the clamp.

[0013] When the scraper blade fits the belt and rises and falls with the belt, the main frame rises and falls accordingly. The mounting bolts installed in the round holes in the bent part of the scraper frame and the bent part of the fixed rod rise and fall in the oblong holes, realizing the movement of the main frame. The scraper blade automatically adjusts the cleaning force of the scraper blade according to the gravity of the main frame and the blade plate.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The utility model provides a clamping self-adjusting single-sided coal-dropping return belt cleaner, which greatly reduces the time required for belt operators to clean coal between the belt and the narrow side of the lane, avoids friction between floating coal and the belt and rollers, reduces belt damage and extends belt life.

[0016] Because the belt cleaner uses the main frame of the belt cleaner and the weight of the polyurethane scraper to make the polyurethane scraper always generate friction with the belt to clean the belt through the oblong hole, the polyurethane scraper can be automatically adjusted through the oblong hole to the point where the wear value of the polyurethane scraper is flush with the channel steel, and then the polyurethane scraper can be replaced. It is usually maintenance-free, which can reduce the frequency of belt maintenance personnel adjusting the belt cleaner scraper and save labor maintenance costs. BRIEF DESCRIPTION OF THE DRAWINGS
