The invention discloses a ZWY mine crawler excavation loader multifunctional conveying device, which includes a loader body, the loader body includes a base, a driving crawler is installed on the lower end of the base, and a driver's cab is fixed on the upper end of the base. An excavation mechanism is installed on the front side of the base, and a rolling feeding mechanism and a transmission mechanism are respectively installed on both sides of the rear end of the base. The two sides of the rectangular dish are connected through. A rolling block is fixed on the inner bottom of the rectangular dish close to the side of the excavation mechanism. The upper end of the rolling block is provided with a rolling roller 1 and a rolling roller 2, and the rolling roller One and rolling roller two are all rotatably installed on the front and rear end inner walls of the rectangular dish. The invention has compact structure and stable operation, and can adjust the position and height of the ore discharge point, so as to meet the requirements of ore loading under different working conditions and ensure the safety of mining.

The invention relates to a coal tar whole-fraction fluidized bed hydrogenation method which comprises the following steps: (1) heating coal tar whole fraction and mixing with circulation oil of a fluidized bed reactor; (2) mixing the mixture in the step (1) and hydrogen, dissolving the hydrogen, and enabling the mixture to enter a gas-liquid separator; (3) enabling a gaseous phase on the top of the gas-liquid separator in the step (2) to enter a fixed bed hydrogenation reactor from the top of the reactor, and enabling a liquid phase to enter the fluidized bed reactor from the bottom of the reactor so as to carry out a hydrogenation reaction; and (4) arranging a three-phase separator on the upper part inside the fluidized bed reactor in the step (3), discharging the gaseous phase separated from the three-phase separator from the top of the fluidized bed reactor to the fixed bed hydrogenation reactor in the step (3), and taking at least one part of the liquid phase through a circulatory system as the circulation oil in the step (1). Compared with the prior art, the method disclosed by the invention has the advantages that the steady operation problem existing in coal tar whole-fraction fluidized bed hydrogenation can be effectively solved, and the coal tar whole-fraction fluidized bed hydrogenation reaction effect is improved.

A method for network scanning based on the trunk protocol, comprising the steps of: 1) switch configuration acquisition and analysis; 2) setting a test port as a trunk mode; 3) constructing and sending a test packet; 4) receiving and filtering a response packet; 5) ) data restoration and processing. The present invention also relates to a network scanning system based on the trunk protocol dedicated to the method, including the following sequentially connected modules: 1) switch configuration acquisition and analysis module, 2) setting the test port as a trunk mode module, 3) constructing and sending the test Data packet module, 4) receiving and filtering response data packet module and 5) data restoration and processing module. By adopting the method and system of the present invention, all VLANs or network segments on the switch can be scanned at one time without modifying the configuration of the switch, which can effectively improve the network scanning efficiency and avoid changing the configuration of the switch from affecting the stable operation of the information system.

The invention discloses a shaft displacement prevention device for a mechanical transmission type grate cooler. The device comprises a base, mounting mechanisms are arranged at the two ends of the base, a rotating shaft and an auxiliary shaft are movably arranged between the two mounting mechanisms through bearings correspondingly, fixing discs are fixedly arranged on the outer sides of the two ends of the middle of the auxiliary shaft, a baffle is fixedly arranged on the outer side of the middle of the rotating shaft, the baffle is arranged between the two fixing discs, and fixing mechanismsare arranged at the two ends of the rotating shaft and the auxiliary shaft. According to the device, the auxiliary shaft is driven to rotate through a gear while the rotating shaft rotates, meanwhile,a ball is driven to rotate while rotating, then lubricating oil on the inner side of an oil box is brought to the bearing where the rotating shaft is located and the bearing where the auxiliary shaftis located through the ball for lubricating and cooling, so that the situation that the bearings are damaged and broken due to the facts that rotating is performed for a long time and the lubricatingoil is not provided for lubricating and cooling and other problems occur, so that the production efficiency is reduced is avoided.

The present invention provides a data communication processing system for a power distribution network station area. The station area monitoring server receives the distribution data acquisition request information sent by the distribution monitoring terminal, parses the information into the requested distribution data in a preset format, and then converts the pre-set The requested power distribution data in the set format is sent to the station area data acquisition device; the station area data acquisition device receives the requested power distribution data in the preset format, and reads the power distribution data in the storage; according to the agreement with the station area monitoring server The preset format analyzes the power distribution data, encapsulates the power distribution data according to the power distribution data format applicable to the power distribution monitoring terminal, and sends the encapsulated power distribution data to the power distribution monitoring terminal through the station area monitoring server. According to the information received by the power distribution monitoring terminal, the monitoring personnel can obtain the status of the power distribution network and power distribution equipment, know the stability of the distribution station area in any time period, and configure the station area according to the state of the data in each time period information.

The invention relates to the technical field of cutting devices, and discloses a pneumatic precision cutting machine for aluminum materials, which includes a base plate, a workbench is fixedly installed on the top of the base plate, and a power seat is fixedly installed on the top of the workbench. The output end of the power base is fixedly equipped with a cutting blade, the side of the power base is fixedly equipped with an external shield matched with the cutting blade, the bottom of the inner cavity of the workbench is fixedly equipped with a rotating table, and the outer surface of the rotating table Surface fixed installation with outer casing. The aluminum pneumatic precision cutting machine divides the cutting machine into two parts: cutting and feeding through the cooperation of the rotating table, the outer casing, the fastening plate and the adjusting bolt, so that the aluminum cutting machine can cut the aluminum During the process, the angle between the automatic feeding device and the cutting blade can be adjusted freely, so as to ensure that when the cutting angle of the device is adjusted, its automatic feeding function will not be affected at the same time.
