2results about How to "Improve transportation effect" patented technology

This utility model discloses an auxiliary equipment for the transportation and installation of building pipelines, relating to the field of pipeline construction technology. It solves the problems of inconvenient transportation and installation of building pipelines in existing technologies. It includes at least two towing trolleys, each trolley comprising self-locking casters, two movable wheels, a pipeline placement groove, and fastening structures opposite each other on both sides of the groove. The fastening structures include support rods, screws, a top plate, and an arc-shaped clamping plate. The support rods are mounted on the trolley frames and have screw holes. The arc-shaped clamping plate has a receiving chamber with a through hole, the size of which is smaller than the size of the top plate. The fixed end of the screw spirally passes through the screw hole and slides through the through hole, and is fixedly connected to the top plate. This auxiliary equipment for the transportation and installation of building pipelines is used for the transportation and auxiliary installation of building pipelines, enabling convenient and safe transportation of pipelines with low labor intensity, while providing support and assistance for pipeline installation, thus improving pipeline installation efficiency.

The utility model provides a handheld environmental monitoring soil sampling device, which relates to the technical field of soil sampling, and comprises a sampling barrel, a convenient locking mechanism is arranged above the sampling barrel, the convenient locking mechanism comprises a holding ring, the inner wall of the lower end of the holding ring is rotatably connected with the outer part of the upper end of the sampling barrel through a bearing, and the inner wall of the lower end of the holding ring is connected with the sampling barrel. An annular driving plate is fixedly connected to the inner wall of the upper end of the holding ring in a sleeving mode, inclined grooves distributed in an annular array mode are formed in the upper end of the annular driving plate, limiting sliding grooves distributed in an annular array mode are formed in the upper end of the sampling barrel, and rapid locking and unlocking of the adjusting rod can be achieved by rotating the holding ring through a convenient locking mechanism; the soil sampling device has the advantages that a traditional complicated operation mode is avoided, the use convenience is greatly improved, sample scattering caused by air entering during sampling is avoided, an adjusting rod can drive an extrusion block to extrude out a soil sample in the sampling barrel, sample collection is facilitated, the adjusting rod can be contracted to reduce the overall size of the device, and the device is convenient to carry and transport.
