The invention relates to the technical field of cable installation, and discloses a high-rise building installation cable releasing device, which comprises a first fixing plate, a second fixing plate, a walking mechanism and a guide mechanism, one end of the first fixing plate and one end of the second fixing plate are fixedly connected with an installation plate, the top of the first fixing plate is rotatably connected with a cable coil, and the cable coil is rotatably connected with the top of the second fixing plate. A cable body is wound on the outer wall of the cable roll, the other end of the cable body is clamped on the walking mechanism, a first winch is fixedly connected to the top of the first fixing plate, a first traction rope is wound on a winding drum of the first winch, and the other end of the first traction rope is fixedly connected with the walking mechanism. According to the cable laying device, the walking mechanism is driven to move through unwinding of the first winch, winding of the second winch and pulling of the first pulling rope and the second pulling rope, so that the cable body is driven to move, laying of the cable body is achieved, and the efficiency is high.

The utility model provides a pumpkin seeding machine with the function of covering soil, which comprises a bottom plate, two groups of mounting ports are arranged on the bottom plate, a load plate is slidably connected to the mounting ports, an adjusting assembly is assembled between the bottom plate and the load plate, a film covering unit is fixedly installed on the front side of the bottom plate and the load plate, seeding units are fixedly installed on the top of the bottom plate and the load plate, soil covering units are fixedly installed on the inner sides of the two sides of the load plate and the bottom plate, and a slotting unit is fixedly installed on the rear side of the bottom plate and the load plate. The adjusting assembly comprises a second adjusting rod and a first sliding rod, and the first sliding rod and the second adjusting rod are respectively and oppositely installed in the mounting ports and penetrate through the load plate. The utility model realizes the free switching of 1-3 lines through the sliding design of the load plate, and is suitable for different agricultural requirements. The film covering unit enables the device to lay and press the film, and assists the personnel in the laying operation. The slotting, seeding, film covering and soil covering of the three-line planting path can be completed at one time, and the work amount of the personnel is reduced.

This invention belongs to the field of mine roadway support technology, and relates to a high-precision automatic netting device and control method for mine roadways. It includes a pitch component, a telescopic drive mechanism, a slewing mechanism, a netting grabbing mechanism, and a binocular vision sensing component. The pitch component is fixedly installed on the anchor bolt trolley frame and connected to the slewing mechanism via the telescopic drive mechanism. The front end of the slewing mechanism is connected to the netting grabbing mechanism. The binocular vision sensing component is installed on both the slewing mechanism and the netting grabbing mechanism. Employing a multi-stage telescopic, slewing, and pitch multi-degree-of-freedom mechanism, it achieves netting grabbing and laying operations in complex roadway spaces. Integrating binocular vision, lidar, and hybrid vision servo technology, it achieves high-precision positioning throughout the entire process of netting grabbing, wall contact, and hole alignment, significantly reducing problems such as netting offset and excessive contact gaps, thus improving the construction quality of roadway support. The remote manual monitoring operation mode significantly improves the safety of mine roadway support operations.

The application relates to a prefabricated assembly type concrete pavement structure and a construction method thereof, and relates to the field of building construction road engineering technology, which comprises a prefabricated concrete pavement slab, which is prefabricated in advance according to pavement size in a factory; an end abutting mechanism, which is provided with a first moving channel in a central position in the prefabricated concrete pavement slab along a length direction or a width direction of the prefabricated concrete pavement slab, and is slidingly arranged in the first moving channel; when not subjected to external force, part of the end abutting mechanism is located outside the first moving channel; a side positioning mechanism, which is provided with a second moving channel perpendicular to the first moving channel in the prefabricated concrete pavement slab, and is movably arranged in the second moving channel; after the end abutting mechanism completely enters the first moving channel, the side positioning mechanism is automatically pushed out of the second moving channel by the end abutting mechanism and abuts against a road side wall. The application has the effect of improving the problem that the construction period of the concrete pavement is too long during construction.
