The invention discloses a beam-column type support and a method for constructing multi-section adjacent bridges using same. Upright posts of the beam-column type support are transversely and vertically connected into a whole in a fixed way and propped against a basic part which transversely runs through the pouring position of each bridge section by a support backout device. When pouring the multi-section adjacent bridges, the support, as a whole, can be moved transversely to the pouring position of each bridge section along the basic part; after the bridge sections in the same transverse rows are poured, the support, as a whole, can be moved to an access road which is on the side of the bridge and extends along the laying direction of the bridge; after being vertically moved to the position corresponding to the next pouring position of the bridge along the access road by a flat wagon, the support is transversely moved to the basic part which is on the bottom of each bridge section of the pouring position of the section, extends transversely and runs through the pouring position of each bridge; by transversely moving the support along the basic part, each bridge section of the pouring position of the section can be poured. In the method, the support can be moved transversely and vertically as a whole without dismounting, thus shortening the pouring construction period of the bridge and improving the construction efficiency.

The invention relates to a low-voltage cabinet of a box-type transformer station, and the box-type transformer station with same, wherein the low-voltage cabinet of the box-type transformer station comprises a wire inlet unit, a feeder line unit, a capacitance compensating unit and a secondary instrument unit. The wire inlet unit, the feeder line unit, the capacitance compensating unit and the secondary instrument unit are arranged in one cabinet body and furthermore are separated from one another through corresponding baffle plates. The wire inlet unit and the secondary instrument unit are parallelly arranged in the transverse direction of the cabinet body. The feeder line unit is arranged below the wire inlet unit and the secondary instrument unit. The capacitance compensating unit is arranged at one side of the wire inlet unit in the transverse direction, which deviates the secondary instrument unit, and furthermore the lower part of the capacitance compensating unit is arranged parallelly with the feeder line unit in the transverse direction. The wire inlet unit of the low-voltage cabinet is arranged at the middle part of the cabinet body in the transverse direction, thereby realizing convenient connection with other units. Furthermore the capacitance compensating unit and the feeder line unit can be distributed to relatively large spaces, thereby realizing reasonable layout and high space utilization rate. Furthermore, the units are arranged in a same cabinet body, thereby realizing benefit for assembling and maintenance, reducing detaching workload and improving operation efficiency.

The invention relates to the field of rolling mill guide, in particular to an adjustable guide. The adjustable guide comprises two guide bodies which are vertically arranged and two guard plates which are correspondingly arranged up and down, wherein the two guide bodies are positioned on the left and right sides of the two guard plates; a connecting shaft group which is horizontally arranged and perpendicular to the guide bodies is connected between the two guide bodies, and consists of two connecting shafts which are arranged in parallel up and down; the two guard plates are fixedly arranged on corresponding connecting shafts respectively; a guide passage for a material to pass through is defined by the two guide bodies and the two guard plates; the guide bodies are provided with square holes of which the hole cores are arranged along the axes of the connecting shafts; square pressing blocks are arranged in the square holes; the middle parts of the pressing blocks are provided with middle holes for the connecting shafts to penetrate through; at least one plug block is arranged between the outer side walls of the pressing blocks along the horizontal direction and the inner hole walls of the square holes; a locking unit for limiting the movement of the pressing blocks along the axes of the connecting shafts is also arranged beside one pressing block. The adjustment is easy, and the working efficiency is improved.

The invention relates to the field of skip devices, and in particular to a method for rapid replacement of a large coal mine skip. The method comprises the steps that an upper body and a lower body ofthe skid are separately conveyed in and out by disassembling a skid middle flange; the height of a first layer heapstead and the height of a sleeve frame in and out of the skip are lowered; an open-close type movable sleeve frame is arranged, and the sleeve frame and a cage guide are opened and closed integrally; the difficulty and workload of dismantling and installing and restoring the sleeve frame are reduced; a spare skid is stored in a warehouse, and the storage in the heapstead or a headframe is canceled; the floor area and load of the heapstead or the headframe and lifting equipment isreduced; a temporary rail mounting beam is reserved during the design of the sleeve frame and is connected with an outer fixing track of the sleeve frame; and a temporary track is installed quickly when the skip is replaced. An outlet headframe is paved on the track, the transfer of the skid in the headframe is avoided, the movement is smooth, and the process is less. The technical defects of high cost, large occupied area and long time consuming in the existing technical problems are solved. The method for rapid replacement of the large coal mine skip is simple, quick, low in cost and practical.

The invention discloses a servo winch rope aligning device. The servo winch rope aligning device comprises a steel wire rope a which is connected to the outer sides of three ling-ring-shaped single-wheel round head ring tackles in sequence in an inverted-triangle shape, the two ends of the steel wire rope a are connected to the two ends of a pulley block correspondingly, and the joints are fixed through a plurality of rope clips b; the ling-ring-shaped single-wheel round head ring tackle located at the bottom is buckled to one end of a rigging turnbuckle; bow shackles a are buckled on the pulley block, each bow shackle a is buckled with one end of a safety rope a, the middle of the safety rope a is buckled with one end of a safety rope b, and the other end of the safety rope b is connectedto a bow shackle b in a penetrating mode; the bow shackle b is buckled with a lug plate b; the joint between the safety rope a and the safety rope b is fixed through a plurality of rope clips b; anda fast rope is connected into a guide wheel set in a penetrating mode. According to the servo winch rope aligning device, the swinging range of a fast rope of a boring winch is decreased, the phenomenon that ropes are disordered or squeezing occurs in the drilling process is avoided, and the service life of the drilling steel wire rope is prolonged.
