The invention discloses a rapid in-place device and a rapid in-place method for a prefabricated wallboard of a prefabricated building. The rapid in-place device comprises a ground rail, a pair of vertical guide rails and a horizontal pushing guide rail mechanism, wherein the ground rail is arranged at the outer side of a building framework; the vertical guide rails are vertically arranged on the ground rail at intervals and can move along the ground rail; the horizontal pushing guide rail mechanism is vertically arranged on the vertical guide rails, can move up and down along the vertical guide rails and comprises a horizontal pushing guide rail frame and a horizontal guide rail cross beam used for hoisting the prefabricated wallboard, and the horizontal pushing guide rail cross beam can move along the direction which is close to or is away from the building framework relative to the horizontal pushing guide rail frame. According to the device and the method, disclosed by the invention, in-place installation and temporary supporting can be completed in one step, the in-place efficiency of the prefabricated wallboard of the prefabricated building can be increased, the problem of the low in-place accuracy of the prefabricated wallboard of the prefabricated building can be solved, and the risk of working high above the ground of a worker can be reduced.

The invention relates to a high-altitude crimping apparatus of a power transmission line. The apparatus comprises a hydraulic scissors, a hydraulic wire stripper, and a crimping machine. The crimping machine is on a transverse ladder and can move on the transverse ladder; two ends of the transverse ladder are respectively equipped with a lifting hook and a cross-arm hasp, wherein the lifting hookand the cross-arm hasp are used for supporting and suspending the transverse ladder; the transverse ladder can make rotation relatively to the transverse ladder. An oil pump is arranged at an end of the transverse ladder, wherein the end corresponds to one end that is provided with the cross-arm hasp. According to the invention, the end of the cross-arm hasp is connected with a tower corner iron and the lifting hook is connected with a fixed cable or a wire rope, so that the whole transverse ladder can be installed and fixed in the air; a worker can complete the compression joint work of conducting wires on the transverse ladder, so that a reliable working platform is provided and danger of high-altitude working can be reduced; when the conducting wires can not be bent, the crimping machine can move or make rotation by a mobile frame body and a base plate support of the crimping machine, so that labor intensity of the working people is reduced. Besides, the working efficiency can be improved rapidly. The apparatus has advantages of compact structure and safety and reliability. And the apparatus is also easy to install and use.

The invention discloses an integral bracket construction method for a cover beam, which comprises the following steps: mounting an A-frame and a lifting mechanism on a pier column; paving sleepers on the ground so as to level the ground; connecting I-shaped steel and square steel to form an integral bracket, and then placing the integral bracket on the sleepers; placing corresponding materials on the integral bracket, and lifting the integral bracket by using the lifting mechanism; confirming that the performance reaches the standard in the lifting process of the integral bracket, and then putting the integral bracket into production; fixing the lifted integral bracket on the corresponding position of the pier column; confirming that the integral bracket fixed on the pier column is safe, and then dismounting the A-frame and the lifting mechanism on the pier column; carrying out construction on the pier column; after the construction of the cover beam, lowering the integral bracket onto the ground; and repeating the steps so as to carry out construction of the next cover beam. The integral bracket construction method disclosed by the invention overcomes the problems of high construction difficulty and high cost of the conventional method and is obviously shortened in construction period, high in safety performance, environment-friendly and energy-saving.

The invention discloses a high-altitude large-span cantilever structure construction platform and a method. The construction platform comprises: a concrete structure, a column embedded in the concrete structure, a parallel chord truss arranged on the column, and an upper chord arranged on the upper chord of the truss The secondary beam, the lower chord secondary beam arranged on the lower chord of the truss, the pressing plate or the supporting formwork arranged on the upper chord secondary beam. The construction platform in the present invention can be used as a construction platform of a high-altitude and cantilevered concrete structure, and is especially suitable for situations with large suspended height, large span and large construction load. The construction platform is simple in structure, convenient in construction and installation, and can effectively solve the construction problems of high-altitude and large-span cantilevered structures. The cross operation improves the construction efficiency of high-altitude large-span cantilever structures.

The invention discloses a lamp shell. The lamp shell comprises a shell, a rotating component, a lamp housing and a locking component, wherein thread holes are respectively formed in two opposite sides of the shell; the rotating component comprises two rotating rods; the rotating rods comprise fastening parts and connecting parts connected in sequence; the fastening parts are respectively in threaded connection into the thread holes; the lamp housing is rotationally connected to the two connecting parts; and the locking component is in threaded connection to the shell, and is used for locking the shell on the lamp housing. As the rotating rods are respectively arranged at two opposite sides of the shell, and the lamp housing is rotationally connected to the two rotating rods, when a maintenance worker repair the lamp shell in a cover opening manner, the maintenance worker has no need to support the lamp housing by one free hand, and thus the safety is improved; as the locking component is arranged on the lamp housing, the tightness of the lamp shell is guaranteed, elements accommodated in the lamp shell are protected, and the reliability of the lamp shell is improved. In addition, the invention further provides a lamp.

The invention discloses a connection device for connecting in and out of tension insulator strings of UHV transmission lines. Frame, the top and the bottom of the fixed frame are respectively fixedly connected with the top of the fixed clamping block by several bolts, and the top of one of the clamping blocks is rotatably connected with a fixed clamping block through a movable pin. This scheme slides on the climbing rod through the mutual cooperation of several climbing mechanisms, which facilitates the adjustment of the horizontal height of the insulator. Through the installation of the sliding column, the first hinge seat is driven by the chute to move up and down the second hinge seat. Activities, while sliding, cooperate with the connecting plate to quickly make the climbing block slide up and down under the action of the crawler belt, reduce the danger of workers working at heights, and improve the stability of insulator installation.
