A wind-up method for the main cable used for suspension bridge features that its reel is a combined one, which is composed of a front end cover, a back end cover, and several horizontal arc plates between said front and back end covers and with one front end fixed to said front end cover and one back end hinged to said back end cover. There is a gap between adjacent two arc plates. After said main cable is fully wound, the front end cover is detached and the arc plates are gathered up to become a conic shape, so unloading the wound cable easily.

A heater with drying, a plurality of heating plates are connected in series through a rotating shaft, the rotating shaft is a hollow cylindrical structure, a fan is installed in one end of the rotating shaft, and the cylindrical surface of the rotating shaft has an axial strip opening; the heating plate comprises a heating panel, There are a plurality of air outlet holes on the heating panel, and there are ventilation channels under the air outlet holes, and the ventilation channels are connected with the strip-shaped openings of the rotating shaft; in addition to the ventilation channels below the heating panel, electric heating wires are laid. mode, when folded it is drying mode. The heating panel does not directly touch the towel to avoid the danger of burning the towel. Through the temperature and humidity sensors, the device will automatically power off after the towels are dried.

The invention relates to a double self-elevating external climbing frame for a super high-rise building, which is a building auxiliary equipment, which includes a frame bottom I-beam and a vertical I-beam. There is a connecting moment groove on the top of the beam, and a connecting disc is fixed on the side of the I-beam at the bottom of the frame. The side of the connecting disc is provided with a connecting screw hole and an installation screw hole. There are connecting rods between the two groups of I-beams at the bottom of the frame. The two ends of the side wall of the connecting rod are symmetrically provided with connecting threads, the bottom end of the vertical I-beam is fixed with a connecting arc plate, the side of the connecting arc plate is provided with a through screw hole, and the center of the side of the vertical I-beam is provided with a threaded hole. There are multiple sets of horizontal pieces between the beams. There is a bottom support piece between the bottom horizontal piece and the I-beam at the bottom of the frame. Auxiliary support pieces are set between the horizontal pieces. Scaffolding boards are laid above the horizontal piece. A side fixture and an inner fixture are installed on the outer groove surface of the vertical I-beam, and a protective side plate is installed between the side fixture and the inner fixture.

The invention discloses a cable spanning device for electric power construction, comprising a transport vehicle, a support frame and a mounting platform are installed on the transport vehicle, a lifting mechanism is installed on the mounting platform, and a supporting mechanism is installed on the top of the lifting mechanism , A first connecting rod and a second connecting rod are installed on the lifting mechanism, one end of the first connecting rod and the second connecting rod is installed on the lifting mechanism, and the other end is installed on the supporting mechanism. The invention only needs to be moved to the working position under the action of the transport vehicle, without assembly and disassembly, which greatly improves the work efficiency, and the lifting mechanism can open the support mechanism to achieve the purpose of crossing obstacles and the erection of cables , and the lifting mechanism can retract the supporting mechanism, which ensures the safety of the device during transportation. The setting of the two supporting mechanisms ensures the stability of the device and prevents the Tilting or even damage greatly guarantees the service life of the device.

The invention relates to an old bridge demolition construction process, in particular to an in-water old bridge cover beam demolition platform erecting method, which comprises the following steps: S1, erecting a straining beam support; S2, erecting a platform main beam; S3, erecting a platform distribution beam; S4, lifting a platform support; S5, mounting a hoop; and S6, establishing an operation space. According to the method, the platform support is pre-assembled on the straining beam and then lifted to the bottom of the cover beam to be temporarily fixed, then the hoop is assembled on the top of the straining beam in the same mode, the straining beam is lifted to the designed height and then fixed through the high-strength bolt, and finally the platform support and the hoop are fixed, so that the platform is erected; the space on the straining beam is fully utilized, so that the erecting process of an old bridge cover beam dismantling platform in water is safe and rapid, the difficulty and danger that bolts penetrate through hoops in a suspended state for fixation are avoided, and safe and rapid erecting of the old bridge cover beam dismantling platform in water is achieved.

The invention relates to a surveillance device for a transport apparatus that comprises a cable carried by N pylons (1-6), characterized in that the surveillance device comprises: at least 2N switches (1a-6b), two switches being provided at each pylon; a safety electric cabinet (8); N+1 electric lines (I-VII) connecting the switches to the safety electric cabinet, the switches being laid in the following manner: a first electric line connects one of the switches of the first pylon to the electric safety cabinet; a N+1st electric line connects one of the switches of the Nth pylon to the safety electric cabinet; the same electric line n connects in series, for any integer n between 2 and N, one of the switches of the pylon n-1 and one of the switches of the pylon n to the safety electric cabinet.

The invention belongs to erecting equipment for railway box girders, and in particular relates to a bridge erecting machine for a small-curve railway box girder, which solves the problem that the conventional bridge erecting machine cannot meet the requirement of the erection of the small-curve railway box girder. The bridge erecting machine for the small-curve railway box girder comprises a box-shaped girder which is arranged on a front outrigger, an auxiliary outrigger and a back outrigger, wherein the bottom of the back outrigger supports on back outrigger trolleys; the fronting end of the box-shaped girder is connected with a cantilever beam; both sides of the width of the cantilever beam are provided with longitudinal overhead rails; a cantilever crane is arranged on the longitudinal overhead rails; the cantilever crane comprises a longitudinal movement mechanism and a horizontal movement mechanism; the horizontal movement mechanism comprises a horizontal movement rail frame; a bogie is arranged on the horizontal movement rail frame, and the horizontal movement quantity of the bogie is delta= SL / R; the back outrigger and the auxiliary outrigger are provided with a vertical hinge mechanism; and the two back outrigger trolleys are provided with differential mechanisms. The bridge erecting machine has the advantage that a wide structure of the horizontal movement mechanism of the cantilever beam is matched with the vertical hinge mechanism of the back outrigger and the auxiliary outrigger and the differential mechanisms of the two back outrigger trolleys to realize the erection of the small-curve box girder with a 500-meter curvature radius.
