The invention discloses a self-movable herringbone ladder. The self-movable herringbone ladder comprises a top seat, a front frame body, a rear frame body and a linkage support, wherein the top partsof the front frame body and the rear frame body are correspondingly connected with the top seat in a hinged mode; universal wheels for moving are installed at the bottom ends of the front frame body and the rear frame body correspondingly; a front frame upper transverse bar and rear frame upper transverse bar are arranged on the upper parts of the front frame body and the rear frame body correspondingly; and a placing platform is fixed above the front frame upper transverse bar in a welded mode, and a power pedal is erected above the rear frame upper transverse bar. According to the self-movable herringbone ladder, people is enabled to control the movement of the ladder on the ladder, going down and pushing the ladder are not required, the time of traveling to the destination is saved, andthe working efficiency is improved; and the front frame upper transverse bar is connected with the placing platform, so that when the people use the herringbone ladder, articles can be placed on theplacing platform in advance, and use is convenient.

The invention relates to a conical rotor DC permanent magnet braking motor, which includes a casing, a main shaft, a stator core, a rotor core and a brake. Swimmingly supported on the left and right end covers, a spring thrust device is provided between the rotor core and the left end cover, the brake is a friction brake, including matching dynamic brake parts and customized brake parts, and the dynamic brake parts are fixed on the left end. On the main shaft outside the cover, the custom stopper is fixedly connected with the left end cover, the main shaft speed is 200r / min-900r / min, and the braking torque is 50N / m-2000N / m. The invention enables the DC permanent magnet motor to have a braking function, and when it is used in occasions such as driving a crane reel, the structure of the whole machine can be significantly simplified, the overall volume can be reduced, and the manufacturing cost and operating cost can be reduced.

The invention relates to the technical field of casters, in particular to a universal caster, including a height adjustment braking module, an anti-collision module, a rolling module, a power storage module, and a microcontroller. The top of the universal caster is provided with a support , the support is in the shape of a boss; a shell is provided under the support of the universal caster, and the shell is in the shape of a hollow boss; the height-adjusting brake module is located under the support, and the height-adjusting brake module is used to adjust the universal The height of the caster, and slow down the speed of the universal caster and prevent rolling; the anti-collision module is located inside the housing, and the anti-collision module is used to prevent the universal caster from colliding with other objects; the rolling module is located under the support shaft, rolling The module is used for the rolling of the universal caster; the power storage module is located under the support shaft, and the power storage module is used for the electric energy of the universal caster; the invention can better adapt to the height of the universal caster in different applicable occasions, making the braking more convenient , the anti-collision process is automated, and saves power during use.

The invention discloses a medical suspension bridge. The medical suspension bridge comprises a slide carriage and a suspension bridge cross beam, wherein the slide carriage can slide along a sliding rail of the suspension bridge cross beam; a brake mechanism is arranged on one side of the slide carriage; and the brake mechanism can respond to the operation of an operator to be selectively in contact with the lower surface of the suspension bridge cross beam. In the using process of the medical suspension bridge, automatic drifting of equipment caused by external factors can be avoided after the equipment stops. The medical suspension bridge has the advantages of convenience for assembling and disassembling and low cost. The invention also discloses the slide carriage which can slide along the suspension bridge cross beam. The brake mechanism is arranged on one side of the slide carriage. The brake mechanism can respond to the operation of the operator to be selectively in contact with the lower surface of the suspension bridge cross beam and has a brake function.
