This application provides a working platform for demolishing concrete structural beams, belonging to the field of building construction technology. Addressing the problems of low efficiency, long cycle, and high cost in demolishing concrete structural beams, this application provides a working platform for demolishing concrete structural beams, comprising two detachably connected platforms, the length of which is the same as the demolition radius. Each platform includes a platform frame, a load-bearing plate, guardrails, and a limiting structure. The platform frame is composed of multiple welded square steel bars and is placed on the upper surface of the concrete structural beam. The load-bearing plate is positioned above the platform frame. The guardrails are welded to the sides of the platform frame and are parallel to the concrete structural beam. The limiting structure, composed of multiple square steel bars and welded to the lower part of the platform frame, is used to clamp and can move relative to the concrete structural beam. This application allows the beam to be demolished to serve as the load-bearing structure of the working platform, eliminating the need for scaffolding. Furthermore, the working platform can be moved while demolishing during construction until the structural beam is completely demolished, improving construction efficiency, shortening the construction cycle, and reducing construction costs.

The utility model discloses a top suction type smoke gathering device of a steel slag hot splashing pool, and particularly relates to the technical field of steel slag processing devices, the top suction type smoke gathering device of the steel slag hot splashing pool comprises a supporting steel beam, a smoke gathering cover body, a rotating support, a dust collecting device and a steel support, the supporting steel beam is in bolted connection with the hot splashing pool, and the smoke gathering cover is buckled on the steel beam when closed. Smoke is introduced into the dust collecting box through the gas collecting hole, the dust collecting box is connected with the collecting cover through the detachable flange, the smoke collecting cover is opened by 80 degrees during deslagging, the utilization rate of a slag pool is increased, and damage to the cover body is reduced; the cover body is closed by 0 degree after the slag is fully poured, smoke and water vapor generated by spraying and cooling are collected by a dust collection opening in the dust collection box due to the upward drifting characteristic, the cover body is opened for slagging off after the steel slag on the surface layer is cooled, and the operation is cyclically performed until the steel slag is completely cooled and then is carried away. Compared with a rail type movable cover vehicle, the device has the advantages that the tipping angle is 0-80 degrees, the slag stacking amount is increased, the shielding of the trapping cover is small, and the service life is long; ceiling type collection is combined with the check curtain and the dust collection opening, so that the smoke collection effect is good.

The utility model discloses a split type heating block structure which comprises a connecting frame, and the connecting frame and a translation assembly used for pushing the connecting frame to move horizontally are integrated on the outer surface wall of the connecting frame. According to the device, after the tray component is transferred to the corresponding station and fixed, a driving piece is matched with a chain to drive a supporting frame and a sliding base at the top of the supporting frame to slide along a sliding rail, the supporting frame is in linkage with a heating plate till the heating plate is arranged above the tray component, and a lifting motor is matched with a transmission rod and a threaded rod to drive the heating plate to move downwards; the heating metal strip is matched with the heat conduction plate to achieve hot melting of the tray component, the operation space of the top of the tray component is guaranteed through the heating plate which can be arranged in a receding mode, a traditional integrated metal strip is divided into six sets of split bodies of an S-shaped structure, follow-up maintenance is facilitated, and meanwhile the welding efficiency is improved. Once local problems occur, only the split bodies need to be replaced correspondingly.

This invention relates to the field of lightning protection devices, and more particularly to a lightning arrester device, comprising: a mounting base with a positioning groove; a mounting control component disposed in the mounting base and extending relative to the positioning groove, the mounting control component having a first control position and a second control position relative to the mounting base, the first control position being located above the second control position; a lightning rod body inserted into the mounting control component and connected to a grounding device; a plurality of connecting rod assemblies spaced circumferentially along the mounting base, the connecting rod assemblies being hinged to the mounting base and the mounting control component; and a dynamic ring disposed on the extended connecting rod assemblies. This invention can prevent damage to the lightning rod body and injury to personnel, and is convenient for transportation and installation.

The utility model provides a kind of segmented positioning assembly screw lock fixture, including fixed subassembly, the fixed subassembly includes support plate, stepper motor, threaded rod, sliding block, lifting platform, connecting plate and positioning pin;The bottom of the support plate is installed with stepper motor, the output shaft of the stepper motor is fixedly connected with one end of threaded rod, the threaded rod is rotatably connected in the top of support plate, the outer lateral wall of the threaded rod is connected with sliding block by thread connection.The utility model can simultaneously position product mechanism component and PCBA independently and accurately by using segmented positioning structure. By designing special positioning module according to the different structural characteristics of mechanism component and PCBA, high-precision matching is achieved during assembly, effectively avoiding the problem of component collision damage caused by positioning deviation, while improving assembly consistency and product yield. Through the dynamic adaptation of positioning mode and locking process by the liftable positioning mechanism, the operation flexibility is significantly improved.
