Description

Technical Field

[0001] The utility model relates to the technical field of tensioners, in particular to the field requiring linear travel tensioning and shock absorption, such as conveyor sweepers and other equipment. Background Art

[0002] With the development of science and technology, the national economy is becoming more and more prosperous. In the bulk material conveying industry, the demand for long-distance, large-capacity and high-speed conveyors is increasing. The requirements for its sweepers are also getting higher and higher. It is necessary to solve the vibration and tension problems of the sweepers caused by large capacity and high speed. The existing tensioning devices for sweepers still have shortcomings.

[0003] The tensioning degree of the existing sweeper tensioner is generally adjusted by ordinary spiral compression springs, which have low adjustment bearing capacity, poor vibration reduction effect, no damping function, and are prone to problems such as unstable tensioning and large vibration. For this reason, we propose a parallel tensioner. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the utility model provides a parallel tensioner. Since the elastic module, the connecting rod and the connecting frame form a rhombus, and each connecting fulcrum is a rotational connection, the displacement of the connecting frame can be driven by the connecting rod by adjusting the elastic module. The connecting rod has two pieces and is driven by two elastic modules. The structure is more stable. At the same time, it ensures that the force applied to the adjusted fixed ring is parallel to the direction of the vertical pole, which can provide a stable tensioning force. The fixed ring installed on the connecting frame follows the displacement, thereby transmitting the force and displacement to the sweeper rod installed thereon.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a parallel tensioner, comprising a connecting sleeve, wherein an elastic module is laterally arranged on the outer side wall of the connecting sleeve, wherein the elastic modules have two elastic modules and are located on the same side and distributed in parallel in the same direction, and the output shafts of the driving motor are both connected to connecting rods;

[0006] The two connecting rods are in the same direction and parallel, and a connecting frame is connected between the ends of the two connecting rods away from the elastic module. The ends of the connecting rods are hinged to the connecting frame, and the outer side walls of the connecting frame are connected with connecting plates to form a prismatic planar connecting rod mechanism to ensure that the fixing ring can only move parallel to the vertical rod.

[0007] The top end of the connecting plate is inclined and bent toward the side away from the connecting rod, and a fixing ring is connected to the inclined end. The fixing ring and the elastic module are arranged in the same direction, and a limiting mechanism is installed on the fixing ring.

[0008] The elastic module is made of a shell, a square shaft, and elastic rubber. When the square shaft rotates, it compresses the elastic rubber at the four corners of the shell to achieve the effect of tensioning and reducing vibration of the equipment installed on the fixed ring.

[0009] The connecting sleeve is a hollow cylinder with openings at both ends. A vertical pole is movably sleeved inside the connecting sleeve. Both ends of the vertical pole extend out of the connecting sleeve. Both ends of the connecting sleeve are provided with locking and adjustment mechanisms for fixing the vertical pole.

[0010] Preferably, the limiting mechanism includes a lock nut and a fixing bolt, the lock nut is fixed to the outer side wall of the fixing ring and the inner hole faces the center of the fixing ring, the fixing bolt and the lock nut are threaded together and the end of the fixing bolt penetrates the fixing ring.

[0011] Preferably, the locking and adjusting mechanism includes a fastening sleeve, a fastening nut and an adjusting nut. The fastening sleeve is located at the port of the connecting sleeve and is sleeved in the gap between the connecting sleeve and the vertical pole. The fastening nut is threadedly connected to the vertical pole and abuts against the fastening sleeve. The adjusting nut is threadedly screwed onto the vertical pole.

[0012] Preferably, the top end of the vertical pole is connected to a fixing plate, and mounting holes are symmetrically opened on both sides of the fixing plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The connecting sleeve slides up and down along the vertical pole to adjust the height. The locking and adjustment mechanism is used to fix the connection between the connecting sleeve and the vertical pole. The pipe is installed through the guide ring and fixed with a limit mechanism to prevent loosening and falling off. Since the elastic module, connecting rod and connecting frame form a rhombus, and each connecting fulcrum is a rotating connection, the elastic module can drive the displacement of the connecting frame through the connecting rod. The connecting rod has two and is driven by two elastic modules. The structure is more stable. At the same time, it ensures that the force fixed on the fixed ring is parallel to the direction of the vertical pole, which can provide stable tension. The fixed ring installed on the connecting frame follows the displacement, thereby transmitting the force and displacement to the sweeper rod installed thereon. BRIEF DESCRIPTION OF THE DRAWINGS
