Through the arrangement of the lifting unit, the supporting frame, the servo motor, the threaded rod, the threaded hole, the limiting sliding rod and the limiting hole, the servo motor can work to drive the threaded rod to rotate, and through threaded connection with the threaded hole and limiting cooperation between the limiting sliding rod and the limiting hole, the lifting table can be driven to move up and down; and lifting operation of advertising board materials is achieved, carrying, unloading and carrying of the advertising board materials are facilitated, and transfer operation of advertising boards of different working procedures is facilitated.

The utility model discloses a square battery shell combined structure which comprises a battery outer shell, a cover plate is arranged at the top of the battery outer shell, a plurality of bottom plates are inserted into the inner wall of the battery outer shell, a splicing bottom box is arranged at the bottom of the battery outer shell, and a supporting and separating assembly is arranged in the splicing bottom box. The supporting and separating assemblies are symmetrically arranged on the left side and the right side relative to the bisector of the splicing bottom box. The supporting and separating assembly comprises a reciprocating ball screw fixedly connected to the inner wall of the splicing bottom box, a mounting plate is connected to the top of the reciprocating ball screw, an electric cylinder is mounted on the top side of the mounting plate, and a top plate is connected to the top of the electric cylinder and located at the bottom of the bottom plate. According to the device, the spliced bottom box is connected with the battery outer shell in a combined manner, and the battery on the inner wall of the battery outer shell can be automatically supported and ejected out through the supporting and separating assembly in the spliced bottom box, so that the difficulty of taking out the battery from the interior of the battery outer shell is reduced.

This utility model relates to the technical field of hopper equipment, specifically a hopper safety device with lifting and protective functions. It includes a hopper body, a movable baffle body on the top outer side of the hopper body, a large lifting ring on the top side of the hopper body, and a small lifting ring on the top side of the movable baffle body. The outer wall of the hopper body and the outer wall of the movable baffle body are connected by a lifting component. The lifting component includes a guide cylinder and a guide rod that slide against each other. The guide cylinder is connected to the outer wall of the hopper body, and the upper end of the guide rod is connected to the outer wall of the movable baffle body. The movable baffle body of this hopper safety device with lifting and protective functions consists of a U-shaped structure composed of three steel plates, which can shield the two sides and the back. When the hopper is loading and unloading materials, it can effectively prevent materials from accidentally falling and injuring nearby workers, significantly improving operational safety.

The application discloses a construction device for simultaneous installation of a steel structure elevator shaft and elevator equipment, which comprises a shaft, elevator equipment and a construction device, wherein the construction device is located in the shaft, and the construction device is composed of a construction platform, a platform freely lifting force beam, a platform lifting force suspension beam, a platform lifting telescopic support rod and a platform lifting rolling shutter. A rotary support is arranged on the top of the construction platform, the lower end of the rotary support is detachably connected with the construction platform through a buckle assembly, a hoisting mechanism is further arranged on the platform freely lifting force beam, and the platform lifting telescopic support rod is fixed to the middle part of the construction platform. Compared with the prior art, the construction device is designed to take the elevator equipment as a structural support, realizes lifting operation by means of the elevator main guide rail, is located in the shaft, does not need to be erected on a construction outer frame, solves the problem of construction land occupation, and can be simultaneously installed with the elevator equipment, and the construction safety is improved.
