Description

Technical Field

[0001] The utility model relates to the field of equipment for maintaining the position of a conveyor belt, in particular to a deviation adjusting device for a belt conveyor. Background Art

[0002] A belt conveyor is a friction-driven machine that continuously transports materials. It primarily consists of a frame, conveyor belt, idlers, rollers, tensioning devices, and transmission devices. The idlers are crucial components for carrying both the material and the conveyor belt, and they are numerous, accounting for approximately 25% of the belt conveyor's cost. When the conveyor belt deviates from the idlers, it poses a significant risk to the production process. The industry currently addresses this issue through friction adjustment, tapered adjustment, block adjustment, and hydraulic adjustment. However, these adjustment measures present drawbacks such as potential risks, large adjustment errors, and delayed response times. Utility Model Content

[0018] Figure 2 This is a positional relationship diagram of the roller bracket and the deviation adjustment mechanism in an embodiment of the deviation adjustment device for a belt conveyor of the present utility model. DETAILED DESCRIPTION

[0019] The following is further explained in detail through specific implementation methods.

[0020] The reference numerals in the drawings of the specification include: adjusting steel plate 1, screw 2, wheel 3, handle 4, limit bar 5, roller bracket 6, transmission roller 7, conveyor belt 8, roller frame 9, roller bearing 10.

[0021] Example 1

[0022] For belt conveyor deviation adjustment device, such as Figure 2As shown: it includes an adjustment mechanism arranged below two roller supports 6, the roller support 6 includes roller bearings 10, a roller frame 9, a transmission roller 7 and a conveyor belt 8, the roller bearings 10 are located in the installation platform of the equipment, the roller frame 9 is clamped with the roller bearings 10, the roller bearings 10 use existing products, which will not be repeated here, the roller frame 9 is V-shaped as a whole, and the tip of the roller frame 9 is arc-shaped, the transmission roller 7 is fixedly mounted on both sides of the roller frame 9 by connecting plates, and the conveyor belt 8 is located above the transmission roller 7.

[0023] like Figure 1 As shown, the deviation adjustment mechanism includes an adjustment plate 1 that is clamped onto the roller bearing 10 below the roller bracket 6. The end of the adjustment plate 1 away from the roller bracket 6 is hinged with a screw 2. The hinge structure of the end of the screw 2 is as follows: the end of the adjustment plate 1 is provided with a fan-shaped groove, and the end of the screw 2 is rotatably connected to a circular ring plate, which is fastened by inserting a screw into the circular hole in the middle of the circular ring plate. The rotation connection between the circular ring plate and the screw 2 is located in the fan-shaped groove to enable swinging. A limit assembly that converts rotation into linear motion is installed at the end of the screw 2 away from the adjustment plate 1. The limit assembly and the hinge point on the adjustment plate 1 are located on the same straight line in the same horizontal plane. A handwheel is welded to the end of the screw 2.

[0024] The limiting assembly includes a limiting strip 5 extending from one side edge of the roller bracket 6. The limiting strip 5 is provided with a through hole with an internal thread. The through hole cooperates with the thread of the screw 2 to enable the screw 2 to move linearly when the hand wheel is turned.

[0025] The length of the adjusting steel plate 1 and the pitch of the screw 2 are matched and set according to the preset configuration. The preset configuration includes multiple sets of lengths and pitches. For example, the preset configuration has a pitch of 2mm. The length of the adjusting steel plate 1 is 10cm. The hand wheel is turned 5 times to move a distance of 1cm, forming an adjustment result of the adjusting steel plate 1 6° from the initial position.

[0026] The diameter of the lead screw 2 is greater than 12 mm, the width of the adjusting steel plate 1 is 15 mm-25 mm, and the thickness of the adjusting steel plate 1 is greater than 5 mm.

[0027] The handwheel comprises a wheel disc 3 and a handle 4 , wherein the handle 4 is eccentrically fixed on the wheel disc 3 .

[0028] The specific implementation process is as follows:

[0029] Directly facing Figure 1 and Figure 2In the direction of rotation, the handwheel is rotated clockwise and counterclockwise respectively, driving the screw 2 to rotate, allowing the screw 2 to move linearly to the left or right under the condition of thread matching and limiting, thereby driving the adjustment steel plate 1 to swing left or right, specifically according to the rotation direction of the thread on the screw 2; after the adjustment steel plate 1 swings, it drives the roller bearing 10 to swing, ultimately achieving the purpose of adjusting the deviation of the conveyor belt 8. There is no need to extend hands or tools into the operating range of the conveyor belt 8 when adjusting the deviation, ensuring the safety of the operating personnel, and the hands or tools can be directly extended to the bearing of the roller bracket 6 for adjustment, making the adjustment response more timely.
