Description

Technical Field

[0001] The utility model relates to the field of filter presses, and more particularly to a locking mechanism of a plate puller hook. Background Art

[0002] Filter press is the main filtering equipment in the solid-liquid separation machinery industry. The plate puller of the filter press is the key component for pulling the filter plate to remove the filter cake and close it. The plate puller has two slides symmetrically arranged on both sides of the filter press, and the slides are fixed to the main beam of the filter press through brackets; the transmission chain of the plate puller is installed in the slide, and the slide is the component that supports the operation of the plate puller, and the plate puller reciprocates on the slide; a plate puller hook locking mechanism is provided at the rear end of the plate puller, and when the plate puller moves to the end of the slide, the pin shaft on the locking mechanism will be pushed and inserted into the plate puller hook to lock the plate puller hook; such as the "A Pin-Type Plate Puller for Filter Press" proposed by the applicant with authorization number CN201279406Y.

[0003] However, the existing locking mechanism of the plate puller is machined multiple times, which requires multiple flow processes, takes a long time to process and is costly. Utility Model Content

[0004] The purpose of the utility model is to solve the deficiencies existing in the above-mentioned background technology and to provide a locking mechanism for a plate pulling hook of a plate pulling device.

[0005] The locking mechanism of the plate puller hook comprises: a frame, a latch, and a fork rod; the frame is a rectangular groove formed by four plates, including three connected vertical sides and a bottom plate, wherein symmetrical circular latch holes are arranged on two opposite vertical sides, and a fork rod hole is arranged on the other vertical side, the fork rod hole is a long hole, and the fork rod hole and the latch hole are at the same height; the latch is cylindrical, and one end of the latch is a horizontal wedge head, which is convenient for inserting into the plate puller hook; the latch passes through the two latch holes, and the fork rod passes through the fork rod hole and is fixed on the latch.

[0006] Preferably, the frame is cut from a metal sheet by laser, the latch hole and the fork rod hole are directly cut out, and then bent or punched into a groove shape.

[0007] Preferably, a reinforcing rib is welded between two opposite vertical sides of the frame to increase strength.

[0008] The locking mechanism of the plate puller hook of the utility model is arranged at the rear end of the plate puller, and the main frame is cut by laser cutting of metal plates, and the pin holes and the fork rod holes are directly cut out, and then bent or punched into a groove shape; the utility model has a simple structure, is suitable for mass processing, has short working hours and low costs.
