Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary tools for making a belt conveyor head wheel scraper more durable, in particular to an elastic tensioning device capable of adjusting a distance. Background Art

[0002] Belt conveyors are widely used in industries such as mining, coal mining, metallurgy, chemicals, and construction for the continuous transport of various bulk or lumpy materials. During operation, materials can adhere to the conveyor belt, leaving residue on the conveyor belt surface. This residue not only increases the belt load but also affects conveying efficiency and the normal operation of the equipment. Therefore, a scraper is required to remove the material adhering to the belt.

[0003] The working surface of the belt conveyor is prone to material sticking. The head pulley is equipped with a scraper to clean the sticky material. The soft leather installed on the scraper loses its function after wear and tear. It needs to be re-fixed and pressed against the belt again to play the scraping role. The existing hard connection has no movable spacing. If foreign objects fall on the roller, it can only be hard ground.

[0004] Therefore, there is an urgent need to design an elastic tensioning device that can adjust the distance to solve the problem that the existing belt conveyor scraper cannot be softly connected, making it easy to wear and affecting work efficiency. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of the present invention is to provide an elastic tensioning device with adjustable distance.

[0006] The technical solution adopted by the utility model to solve the technical problem is: an elastic tensioning device with adjustable distance, including a hook, a spring, a fixing ring and a telescopic rotating frame, the hook is connected to the spring fixing shaft through a connecting plate, the spring is sleeved on the spring fixing shaft, the spring and the spring fixing shaft are arranged on the upper part of the telescopic rotating frame, and the fixing ring is arranged on the lower part of the telescopic rotating frame.

[0007] Specifically, the hook is welded to the connecting plate, and the lower side of the connecting plate is connected to the spring fixed shaft.

[0008] Specifically, a spring stopper is provided at the lower end of the spring fixing shaft, the spring is sleeved on the spring fixing shaft, and the spring stopper prevents the spring from falling.

[0009] Specifically, the fixing ring is arranged at the lower part of the telescopic rotating frame, and an adjusting bolt is arranged above the fixing ring.

[0010] Specifically, the adjusting bolt is welded on the fixing ring, and the adjusting bolt enables the telescopic rotating frame to move up and down through its own thread.

[0011] Specifically, the telescopic rotating frame adjusts the installation position of the fixing ring by adjusting the bolts.

[0012] The utility model has the following beneficial effects:

[0013] This utility model features an adjustable elastic tensioning device. The existing turnbuckle bolt fixation lacks a flexible spacing. By adding a spring, the rigid connection tensioning is transformed into a flexible elastic tensioning device, which can improve production efficiency, reduce maintenance costs, improve the working environment, and enhance operational safety.

[0016] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely further describe the technical solutions in the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0017] Example 1:

[0018] like Figure 1 As shown, a distance-adjustable elastic tensioning device includes a hook 1, a spring 2, a fixing ring 3 and a telescopic rotating frame 4. The hook 1 is connected to the spring fixing shaft 2.1 through a connecting plate 1.1, the spring 2 is sleeved on the spring fixing shaft 2.1, the spring 2 and the spring fixing shaft 2.1 are arranged on the upper part of the telescopic rotating frame 4, and the fixing ring 3 is arranged on the lower part of the telescopic rotating frame 4.

[0019] After selecting a suitable installation for the hook 1, hang it in the required position. A connecting plate 1.1 is provided at the lower end of the hook 1. The connecting plate 1.1 is used to connect the hook 1 to the spring fixing shaft 2.1. The spring fixing shaft 2.1 is used to fix the spring 2. A spring stop 2.2 is provided below the spring fixing shaft 2.1. The spring stop 2.2 is used to prevent the spring 2 from falling. The spring 2 is sleeved on the outside of the spring fixing shaft 2.1. The spring 2 is used to provide telescopic and tensioning force to the soft connection of the secondary device. A fixing ring 3 is provided below the spring fixing shaft 2.1. The fixing ring 3 is used to fix the installation position of this device. An adjusting bolt 3.1 is provided at the upper end of the fixing ring 3. A telescopic rotating frame 4 is provided outside the adjusting bolt 3.1 and the spring fixing shaft 2.1.
