Meanwhile, the mechanism is stable in operation and free of noise, the comfort degree of the operation environment is greatly improved, and long-term stable operation of equipment is guaranteed.

The utility model relates to the technical field of bag-type dust collectors, and discloses a bag-type dust collector assembly convenient to assemble, which comprises a bag-type dust collector shell, a connecting plate is in threaded connection with the interior of the bag-type dust collector shell, a plurality of connecting ports are formed in the connecting plate, dust collecting bags are inserted into the connecting ports, and the connecting ports are connected with the dust collecting bags. Limiting holes are formed in the two sides of the surface of the connecting opening, and mounting mechanisms are inserted into the limiting holes. According to the bag-type dust collector assembly convenient to assemble, through the arrangement of the mounting mechanism, during mounting, a dust collection bag is inserted into a connecting opening, so that a positioning hole formed in the surface of the dust collection bag is aligned with a limiting hole, then a stretched plug pin is loosened, and the plug pin is driven to return to the initial position under the reverse acting force provided by a supporting spring; and the bolts are inserted into the positioning holes and the limiting holes until the bolts are inserted into the positioning holes and the limiting holes, so that the effect of quickly mounting and dismounting the dust collecting cloth bag is achieved, and the mounting efficiency of mounting personnel is improved.

The application discloses a nine-square-pattern modeling decorative ceiling node, which comprises a main structure, a modeling frame, a decorative assembly and a capping assembly. The main structure comprises a left roof structure and a right roof structure. A plurality of left vertical columns are arranged at the edges of the left roof structure, and a plurality of right vertical columns are arranged at the edges of the right roof structure. A space region formed between two left vertical columns and two right vertical columns is a ceiling. The modeling frame is arranged above the ceiling. The decorative assembly is arranged on the four walls above the ceiling. The ceiling top is sealed by the capping assembly. The construction method comprises the following steps: step one, measurement and line laying; step two, horizontal beam installation; step three, batten frame installation; step four, modeling frame installation; step five, base steel frame installation; step six, decorative plate processing; step seven, decorative plate installation; and step eight, light-transmitting plate installation. The ceiling node has the advantages of seamless, assembly and size and style diversification.

The application discloses a steel pipe concrete sleeper type ballastless track with a damping function and a construction method, and belongs to the technical field of ballastless tracks. The ballastless track comprises two steel rails, a plurality of fasteners, a plurality of steel pipe concrete sleepers, a plurality of track bed plates and a plurality of steel bottom plates. The plurality of steel pipe concrete sleepers are parallel and spaced apart and are inserted into the track bed plates. Each track bed plate is provided with a plurality of upper steel pipes and a plurality of steel springs, the plurality of upper steel pipes are arranged in two rows, each steel spring is inserted into a corresponding upper steel pipe, and the upper steel pipes and the steel springs are arranged to protrude from the track bed plates. The top surface of each steel bottom plate is fixedly provided with a plurality of lower steel pipes, the bottom end of each upper steel pipe is coaxially and slidably inserted into a corresponding lower steel pipe, and the bottom end of each steel spring is inserted into a corresponding lower steel pipe. The steel pipe concrete sleeper type ballastless track with the damping function provided by the application can not only improve the geometric position keeping capacity of the sleepers, but also effectively buffers and damps the sleepers.

The invention discloses an EMB noise control method and device, equipment and a storage medium. The EMB noise control method comprises the following steps: acquiring a current braking state parameter and a braking control instruction of a braking motor; wherein the brake control instruction comprises a brake instruction and a release instruction; and when the rotation direction in the brake control state parameters is different from the target rotation direction under the brake control instruction, the brake motor is controlled to sequentially enter a speed reduction stage, a zero-speed transition stage and a reverse speed increase stage according to the brake control state parameters. According to the scheme, the situation that the impact force at the gear meshing position in the braking and releasing switching process in the EMB system is large is avoided, and therefore serious noise pollution is avoided, the service life of the EMB system is prolonged, and the reliability of the EMB system is improved.

This invention discloses a method for assisting ships in passing through navigation tunnels. It includes the following steps: Step 1: retracting the wheeled drive mechanism; Step 2: moving the towing platform to the waiting ship; Step 3: extending the wheeled drive mechanism; Step 4: the bow of the ship entering the concave structure of the towing platform; Step 5: connecting the towing platform to the bow mooring bollard or hull of the ship; Step 6: activating the wheeled drive mechanism to tow the towing platform and ship; Step 7: moving the towing platform to the exit of the navigation tunnel and disconnecting the towing platform from the bow of the ship; Step 8: the towing platform exiting the channel and waiting for oncoming ships in the double-lane navigation tunnel; Step 9: the oncoming ship passes through by its own propulsion; Step 10: the towing platform connecting with the oncoming ship and towing it through the tunnel; Step 11: the towing platform returning to the starting point of the navigation tunnel. This invention has the advantage of enabling ships to pass through long-distance navigation tunnels under conditions of large water level fluctuations.
