The invention provides an external assembly type tower crane anti-climbing device, and belongs to the technical field of tower crane anti-climbing. Comprising a plurality of frames, a plurality of mounting plates are fixed to the side faces of the frames, the adjacent frames are perpendicularly arranged, the mounting plates between the adjacent frames are vertically aligned, and the vertically aligned mounting plates are fixedly connected through screws. By arranging the frame, the panel and the round rollers, when the tower body has a certain height and an entrance for entering a control room is located on the side face of the tower body, the fence composed of the frame and the panel is fixed to the periphery of the tower body, and when a person wants to climb the tower body, due to the fact that the surface of the panel is smooth and the feet of the person have no acting points, the person cannot climb the tower body, and the safety of the person is improved. When a person binds a hook on a rope and hangs the rope on the tower body, the person wants to climb the tower body with the help of the rope at the moment, and when the feet step on the panel, the round roller rotates, so that the feet of the person have no leveraging point, the person is further prevented from climbing the tower body, and safety protection for the person is achieved.

The application discloses a multifunctional engineering cost drawing device, and relates to the technical field of field surveying and mapping devices.The multifunctional engineering cost drawing device comprises a base, an adjusting table is arranged on the base, a surveying and mapping machine body is arranged on the upper surface of the adjusting table, an inner cavity is arranged at the center position of the base, a plurality of connecting sliding grooves are arranged on the outer surface of the base, the plurality of connecting sliding grooves are in communication with the inner cavity, a connecting sliding strip is slidably connected in the connecting sliding grooves, the connecting sliding strip extends into the inner cavity on the side close to the inner cavity, and a trigger ball is arranged in the inner cavity and rolls in the inner cavity.The multifunctional engineering cost drawing device has double functions, can determine the inclination direction of the base by the sliding state of the connecting sliding strip when the device is placed, can preliminarily understand the horizontal state of the device, can timely remind the staff when the device is inclined during use, can avoid the inaccuracy of surveying and mapping caused by the failure to timely check the leveler, and is convenient for the accuracy of the later engineering cost.
