The invention discloses a detachable material guide mechanism for a belt conveyor, comprising two support bases, the two support bases are arranged opposite to each other, and a guide roller mechanism is installed in the middle of the two support bases, The two ends of the installation guide roller mechanism are respectively fixed to the two supporting bases. This belt conveyor uses a detachable material guide mechanism, which is different from the prior art. The method is detachable, so that the wear-resistant plate of the material guide groove can be disassembled and replaced after long-term use and wear, so as to effectively save the use cost of the equipment and ensure normal and efficient material guide. At the same time, through the set elastic structure , can effectively avoid direct contact wear of the wear-resistant plate, and cooperate with the lifting mechanism, so that the wear-resistant plate can be raised when the material guide is not needed, further avoiding scratching and wear, so as to effectively protect the wear-resistant plate.

Compression-resistant fireproof cable
PendingCN114864167AAvoid the spread of open flamesAvoid direct contact wearClimate change adaptationInsulated cablesIgnition pointOpen fire
A pressure-resistant fireproof cable disclosed by the present invention comprises a cable body and a cable core arranged in the cable body, the outer wall of the cable core is provided with a cable core protection layer, and a protection sheet is used for performing pressure-resistant protection on the cable body. The matching connection between the splicing clamping block and the splicing clamping groove is used for reinforcing the connection between the protection sheet and the cable body. According to the compression-resistant fireproof cable, firstly, anti-impact protection can be carried out on the exterior of the cable body by using the protection sheet, and anti-impact protection can be carried out on the interior of the cable by using the characteristic of elastic metal of the internal heat dissipation metal strips, and secondly, the metal strips and the protection sheet are connected through the heat conduction vertical strips, so that the heat dissipation performance of the cable is improved. Heat can be rapidly dissipated in a heat conduction mode, meanwhile, the characteristic that the memory alloy of the metal strip can recover to the original shape at high temperature can be utilized, when open fire occurs in the cable, the high temperature of the open fire is utilized to promote the metal strip to rapidly recover to the original shape and wrap an ignition point, and spread of the open fire is effectively avoided.

A vibration damping device for a diaphragm coupling and a vibration damping method thereof
ActiveCN112324813BIncreased resonance bandwidthReduce damage rateYielding couplingNon-rotating vibration suppressionCouplingClassical mechanics
A vibration damping device for a diaphragm coupling, comprising an intermediate shaft, the intermediate shaft is a sleeve-shaped structure with a large diameter at both ends and a small diameter in the middle, and the two ends are respectively connected with an intermediate flange and an outer flange, The intermediate flange and the intermediate shaft are connected by a plurality of bolts III, and a plurality of dynamic vibration absorbing members are evenly distributed along the circumferential direction in the large diameter hole of the intermediate shaft. A plurality of groups of diaphragms are arranged in the outer flange, and the diaphragm groups are connected with the intermediate flange and the outer flange through several bolts I. The diaphragm group consists of a plurality of diaphragms and a plurality of damping elements arranged in parallel and installed. The inner hole of the diaphragm group is sleeved with a flange I, the flange I is stepped, and a stopper is installed on the inner side of the diaphragm group. The blue I, the diaphragm group and the block are connected by several bolts II. The placement of the diaphragm group effectively increases the resonance bandwidth. The dynamic vibration absorption device coexists with axial vibration absorption and radial vibration absorption. Power transmission and structural strength.
