The application discloses a kind of contact network maintenance vehicle's deicing equipment, including installation on contact network maintenance vehicle's cross shear type lifting frame, on the cross shear type lifting frame is connected with double-roller type deicing mechanism by multiple-stage oil cylinder, rotating type knocking mechanism and pair of wheel rolling mechanism are respectively arranged at the front and rear ends of the double-roller type deicing mechanism, the rotating type knocking mechanism, double-roller type deicing mechanism and pair of wheel rolling mechanism are sequentially arranged along the advancing direction of contact network maintenance vehicle, and the wire of contact network sequentially passes through rotating type knocking mechanism, double-roller type deicing mechanism and pair of wheel rolling mechanism.The ice layer or ice cone on the wire of contact network can be completely removed by the application, which reduces the labor intensity, improves the cleaning efficiency, and ensures good contact between the wire and the pantograph slide plate.The application is suitable for the technical field of ice layer or ice cone removal on the wire in railway contact network.

The utility model relates to PVC leather production technical field, and disclose a kind of PVC leather production mixing equipment, including chassis, the top of chassis is provided with stirring mechanism, the both ends of chassis are fixedly connected with limiting mechanism, the stirring mechanism includes support, the front of support is fixedly connected with two limit rings, the inside rotation of two limit rings is connected with same stirring drum, the top of support is fixedly connected with servo motor, the output of servo motor is fixedly connected with stirring shaft, the bottom of stirring shaft is through support and extends to stirring drum inside, this PVC leather production mixing equipment, first stirring rod on stirring shaft and second stirring rod of stirring drum inner wall are cross set, and stirring drum and stirring shaft can reverse rotation, form cross shear flow field, material is fully contacted in bidirectional movement, so that material can be fully mixed in stirring process, compared with traditional equipment, greatly improve stirring effect, help to improve the production quality of PVC leather.

The application relates to the technical field of pile foundation construction, and discloses a construction method for improving the bearing capacity and durability of hard stratum stirring pile planting, which comprises the following steps: driving a first group of drill rods to drive a soil breaking drill bit to drill into the stratum and synchronously inject a fluid for cooling, lifting upward after reaching the elevation, and injecting cement slurry, solidifying agent slurry or water into the hole in the drilling lifting stage; using a second group of drill rods to drive a multidirectional stirring drill bit to drill downward and synchronously inject grouting, and carrying out multidimensional cross shearing and mixed mixing of the in-situ broken rock-soil body and the slurry in the hole; controlling the multidirectional stirring drill bit to rotate reversely and lift to separate from the hole position, and carrying out grouting or stopping grouting in the lifting stage; and planting a prefabricated pile into the elevation position before the mixed medium in the hole is initially cured. The application adopts the in-situ soil breaking and non-discharge combined internal and external pipe staggered blade reverse stirring process, overcomes the phenomenon that the cutting resistance of the hard stratum is too large and the mud ball at the bottom of the hole is stuck, realizes uniform forced mixing of the medium in the hole, reduces the pile planting penetration resistance, and improves the overall bearing performance of the composite pile.

The utility model belongs to the field of elevating operation platform especially, a kind of self-locking anti-falling elevating operation platform, to the falling risk problem caused by adventurous behavior (such as exploring body, leaning) or environmental factors (such as inclination, strong wind) of personnel in complex working conditions of existing traditional platform, present and propose the following scheme, it includes concave seat, platform body, driver and safety mechanism.Safety mechanism adopts the sliding limit design of H type moving block and connecting frame, cooperate high-strength connecting rope (steel wire rope / iron chain), when personnel falls, pull distance, form physical hover;Waistband and leg fixed band pass through female buckle-male buckle quick coupling, construct the three-point fixed structure of waist-thigh-inner side of leg, make falling impact force evenly distribute in pelvic and femur, avoid soft tissue injury.Driver adopts cross shear type lifting structure, ensure that platform body stably lifts through the rolling cooperation of guide wheel and guide slot.Door body sets up the double locking mechanism of T type bolt and insert ring, prevent misopening.

The utility model discloses a kind of waste treatment devices for animal experiment, it is related to the field of animal experiment technology, including shell, the upper portion of the shell is fixedly connected with support, the upper portion of the shell is fixedly connected with motor, the output of the motor is fixedly connected with first driving bevel gear, the inside rotation of the support is connected with first rotating shaft, the inside rotation of the support is connected with second rotating sleeve, the upper end of the first rotating shaft is fixedly connected with first driven bevel gear, the surface of the first driven bevel gear is engaged with first driving bevel gear.The utility model passes through the first blade and second blade of bidirectional rotation, so that waste temporarily stores immediately broken and reduce waste volume, reduce processing step, and adopt double-blade bidirectional crushing, can form cross shear and bidirectional tearing force, so that bone and muscle with sinew can be cut off more easily, so that stirring is more efficient.
