The utility model relates to the technical field of railway vehicles, in particular to an elastic wheel with adjustable compression amount, a wheel set and a railway vehicle. The elastic wheel with the adjustable compression amount comprises a wheel rim, a wheel center, an elastic vibration reduction piece, a pressing ring and an adjusting ring. The radial outer edge portion of the wheel center is provided with an installation notch, the pressing ring is arranged on the installation notch, and the pressing ring, the radial outer edge portion of the wheel center and the wheel rim form an annular inner cavity used for containing the elastic damping piece in a surrounding mode. The elastic damping piece is arranged in the annular inner cavity; the wheel center and the pressing ring located on the side of the annular inner cavity are each provided with an annular groove, and the adjusting rings are arranged in the annular grooves. The wheel center and the pressing ring are each provided with an adjusting bolt penetrating in the axial direction, and the end of each adjusting bolt abuts against the corresponding adjusting ring. According to the elastic wheel capable of adjusting the compression amount, the position of the adjusting ring is mainly controlled through the adjusting bolt, so that the compression amount of the elastic vibration reduction rubber part is controlled, and the problem that the wheel is slow is solved; an anti-slowdown base plate and a limiting groove structure are arranged, so that the problems that the elastic wheel is excessively slowdown, and a wheel rim and a wheel center have an overlarge turning angle are solved; in addition, a conductive metal reed is adopted to replace a traditional backflow cable structure, so that the problem of loosening or breakage caused by the fact that the backflow cable is pulled by a wheel or foreign matter is effectively avoided.

This utility model relates to the field of packaging line technology, and more particularly to a packaging line for protecting fragile products. The technical solution includes a conveyor and a base disposed at the outlet end of the conveyor. Carding plates are fixedly disposed on both sides of the base, and a fixing plate is fixedly disposed on the upper surface of the carding plates. A base plate is interlocked between the carding plates. An mounting groove is formed in the fixing plate, and a fixing rod is fixedly disposed inside the mounting groove. An adjusting component for cushioning the product is movably sleeved on the outer wall of the fixing rod. This utility model allows the product to slide down slowly by adjusting the inclination of the base plate, thereby avoiding breakage or chipping of the dough due to excessive impact, reducing the product defect rate, and ensuring that frozen dough slides down at an appropriate speed, thus protecting the integrity of the dough.

The invention discloses holding-up hammer weighing and height measuring equipment which comprises a working table, a weighing instrument is installed on one side of the upper portion of the working table, a placing base is installed above the weighing instrument, a height measuring assembly is installed on the other side of the upper portion of the working table and comprises a transverse moving module, and a supporting base is installed at the output end of the transverse moving module. A lower mounting block is mounted at the lower end of the supporting seat, a lower laser sensor is mounted at the end of the lower mounting block, an upper mounting block is mounted at the upper end of the supporting seat, and an upper laser sensor is mounted at the end of the upper mounting block; the invention further discloses an implementation method of the holding-up hammer weighing and height measuring equipment. The anvil product is weighed through the weighing instrument, and the height of the anvil product is measured through cooperation of the upper laser sensor and the lower laser sensor, so that the measurement result is accurate, the carrying frequency of the anvil product is reduced, the labor intensity is reduced, and the possibility of corner falling of the anvil product is reduced.

The invention provides a positioning bending mechanism with a scale and a segmented bending device for a spine orthopedic rod, belongs to the technical field of surgical medical instruments, is used for pre-bending the spine orthopedic rod before an operation, and comprises a base component, a fixed clamping component, a sliding clamping component, a positioning carriage component and a rotary cylinder component, according to the core working principle, the longitudinal position of a bending point is determined through a linear sliding rail and a side ruler of the linear sliding rail, a bending plane is set through an angle adjusting ruler of a rotating cylinder assembly, and the bending displacement amount is preset and monitored in real time through a displacement measuring instrument installed on an adjusting rotating cylinder; during operation, the bending bolt is screwed to push the bending clamping seat to apply pressure to the orthopedic rod until the deformation of the orthopedic rod reaches a preset value; according to the device, preoperative three-dimensional planning is converted into quantifiable operation in three dimensions of linearity, angle and displacement, closed-loop control from measurement positioning to accurate bending is achieved, and the accuracy, efficiency and repeatability of orthopedic rod forming are remarkably improved.

The application discloses a prefabricated-cast-in-situ combined construction column and a construction method thereof, and relates to the technical field of secondary structures in building engineering. The construction column comprises a lower cast-in-situ section, a middle prefabricated section and an upper cast-in-situ section in the height direction. Two outer side embedded connecting holes are arranged in the middle prefabricated section. When a formwork is supported on site, a non-removable prefabricated concrete outer formwork is supported on the outer side surfaces of the upper and lower cast-in-situ sections, a tension bolt is arranged to pass through the connecting holes of the prefabricated section at the height of the prefabricated section, the tension bolt is fastened to pass through the non-removable outer formwork at the height of the cast-in-situ section without contacting the aerated block. A key groove is arranged on the inner surface of the non-removable outer formwork, and the key groove is overlapped with a cast-in-situ core to form a non-removable formwork for the outer skin of the column after pouring. A zigzag-shaped groove is formed by arranging a masonry at the corresponding height of the upper and lower cast-in-situ sections and filling the zigzag-shaped groove with cast-in-situ concrete. The wall body in the prefabricated section is laid flat. The middle prefabricated load-bearing section is used as a formwork tension support point, the non-removable outer formwork is used to replace the formwork removal, and the elastic buffer side is connected with the masonry. The formwork is reliably supported without penetrating the wall, and the brittle aerated block is protected from being damaged.

The utility model discloses an exhaust fume collecting hood of a fan, which comprises a front plate and a rear plate, an arc-shaped side plate assembly used for connection is arranged between the front plate and the rear plate. The arc-shaped side plate assembly comprises a first connecting plate and a second connecting plate which are connected in sequence; the front plate, the rear plate and the arc-shaped side plate assembly are connected to form a smoke gathering cavity, an air inlet is formed in the lower side of the smoke gathering cavity, an air outlet communicated with the smoke gathering cavity is formed in the arc-shaped side plate assembly, the second connecting plate comprises a flow guide plate right facing the air inlet, and the flow guide plate can more effectively guide oil smoke to enter the smoke gathering cavity; the air inlet is formed below the smoke gathering cavity and is staggered from the air outlet, so that air can be exhausted smoothly, vortex can be reduced, noise caused by vibration of the fan volute can be prevented, and the noise can be reduced; in addition, by means of the design, oil smoke generated by the cooking bench can be effectively collected and discharged, and air in a kitchen is kept fresh.
