Abstract

The utility model discloses a heavy hammer box with a strong anti-falling heavy hammer block, wherein a screw rod is arranged in the heavy hammer box, and matched screw rod holes are arranged on the heavy hammer block, so that when the heavy hammer block is placed in the heavy hammer box, the heavy hammer block can be fixed by utilizing the cooperation of the screw rod and the screw rod holes, and the heavy hammer block is prevented from moving back and forth and left and right in the heavy hammer box. And a spring card is arranged in the screw hole, and the screw is clamped and fixed by the spring card, so that the weight block can be further prevented from moving up and down.

Description

Heavy hammer box with heavy hammer block capable of being strongly installed and prevented from falling

Technical Field

The utility model relates to the technical field of weight boxes, in particular to a weight box with a strong anti-falling weight block.

Background

In a belt conveyor, a tensioning device is an essential part for ensuring proper operation of the apparatus. The vertical heavy hammer tensioning device is the one with the largest application and the widest application range in all tensioning devices. The vertical weight tensioning device mainly comprises a weight box 100 (containing weight blocks), a vertical pulling guide rod 101 and a vertical pulling direction-changing drum 102, as shown in fig. 1-2. In the conventional vertical weight tensioning device, the standard weight block is directly placed in the weight box, so that when the belt conveyor is started, the weight box vibrates, the vibration of the weight block can be caused, and the tensioning force floats. In addition, when the belt conveyor is started, the weight box vibrates up and down, so that the guide rail of the weight box can possibly clamp the guide rod or the ladder stand of the vertical guide rod, and the weight box can topple over.

Disclosure of Invention

Aiming at the defects of the prior art, the utility model aims to provide a heavy hammer box with a strong anti-falling heavy hammer block.

In order to achieve the above purpose, the present utility model adopts the following technical scheme:

a heavy hammer box with a strong anti-falling heavy hammer block comprises a heavy hammer block, a heavy hammer box and a screw; the heavy hammer box is internally provided with a screw rod and a heavy hammer block, the heavy hammer block is provided with a screw rod hole, and the screw rod hole is matched with the screw rod; the screw rod passes through the screw rod hole of the heavy hammer block and is in threaded fit with the screw rod hole.

Further, a spring card is arranged in the screw hole, and the screw is elastically clamped by the spring card.

Further, the heavy hammer block is a reinforced concrete heavy hammer block.

The utility model has the beneficial effects that: according to the utility model, the screw is arranged in the heavy hammer box, and the matched screw hole is arranged on the heavy hammer block, so that when the heavy hammer block is placed in the heavy hammer box, the heavy hammer block can be fixed by utilizing the screw thread fit of the screw and the screw hole, and the heavy hammer block is prevented from moving back and forth and left and right in the heavy hammer box. And a spring card is arranged in the screw hole, and the screw is clamped and fixed by the spring card, so that the weight block can be further prevented from moving up and down.

Detailed Description

The present utility model will be further described with reference to the accompanying drawings, and it should be noted that, while the present embodiment provides a detailed implementation and a specific operation process on the premise of the present technical solution, the protection scope of the present utility model is not limited to the present embodiment.

The embodiment provides a heavy hammer box with a strong anti-falling heavy hammer block, as shown in fig. 3-4, comprising a heavy hammer block 3, a heavy hammer box 1 and a screw 2; a screw rod 2 and a weight block 3 are arranged in the weight box 1, a screw rod hole 4 is formed in the weight block 3, and the screw rod hole 4 is matched with the screw rod 2; a spring card 5 is arranged in the screw hole 4; the screw rod 2 passes through the screw rod hole 4 of the weight block 3 and is in threaded fit with the screw rod hole, and the spring clamping piece 5 elastically clamps the screw rod 2.

In this embodiment, the weight block 3 is a reinforced concrete weight block.

It should be noted that, through setting up the screw rod in the weight case to dispose assorted screw rod hole on the weight piece, when putting the weight piece into the weight case, can utilize the screw rod to fix the weight piece with the screw thread cooperation in the screw rod hole of weight piece, prevent that the weight piece from moving about in the weight case. The spring card is arranged in the screw hole, so that the screw can be further clamped and fixed by the spring card, and the weight block can be further prevented from moving up and down.

Various modifications and variations of the present utility model will be apparent to those skilled in the art in light of the foregoing teachings and are intended to be included within the scope of the following claims.
