Vacuum suction cup type outer jolt ramming device for low-temperature storage tank

Abstract

The invention relates to the technical field of low-temperature storage tank jolt ramming, in particular to a vacuum suction cup type outer jolt ramming device for a low-temperature storage tank. The device comprises two hanging frames which are symmetrically arranged left and right, a lifting frame capable of sliding up and down is arranged between the two hanging frames, a jolt ramming assembly is arranged on the front end face of the lifting frame, two front mounting frames are fixed to the upper portion of the front end face of the lifting frame, a double-shaft motor is arranged between the two front mounting frames, two output ends of the double-shaft motor are connected with driving wheels correspondingly, a rear mounting frame is fixed to the lower portion of the front end face of the lifting frame, the rear mounting frame is rotationally connected with a driven wheel shaft, and two ends of the driven wheel shaft are connected with driven wheels respectively. According to the device, jolt ramming is carrying out on internal accumulated materials outside the low-temperature storage tank, so that the air content among the materials in the storage tank is greatly reduced, the heat insulation performance is greatly improved, and the safety of material storage is improved; and the device can be hung at any position of the low-temperature storage tank, and can be adjusted at any height position on the surface of the low-temperature storage tank through a lifting mechanism, so that jolt ramming can be carried out on the whole tank.

Description

technical field [0001] The invention relates to the technical field of low-temperature storage tank vibration, in particular to a vacuum suction cup type external vibrator for low-temperature storage tanks. Background technique [0002] The interlayer of large-scale low-temperature storage tanks is filled with pearlite. In order to ensure that the filling density meets the design requirements and the effect of cold preservation, the interlayer pearlite must be vibrated during the filling process. [0003] In the prior art, most cryogenic storage tanks are compacted by an assembled vibrator in the interlayer. The traditional interlayer assembled vibrator has some shortcomings in use. First, personnel need to enter the top of the storage tank interlayer to install the vibrator before filling, which has a high risk factor and cumbersome assembly; secondly, the vibrator is inserted into the pearlite The internal vibration work of the product is very destructive to the product p...

Problems solved by technology

The traditional interlayer assembled vibrator has some shortcomings in use. First, personnel need to enter the top of the storage tank interlayer to install the vibrator before filling, which has a high risk factor and cumbersome assembly; secondly, the vibrator is inserted into the pearlite Vibration work is carried out inside the product, which is destructive to the product particle size and affects product quality; the third pair of low-temperature storage tanks that do not have steel beams suspended on the top of the interlayer, and the assembled vibrator in the interlayer cannot be installed for vibration
