Elevator space detection device

The utility model relates to the technical field of elevator detection, and provides an elevator space detection device which comprises a base, a support, a laser radar, a rotation angle detection module and a laser ranging module. The laser radar is fixed on the support and used for measuring the spatial distance in the horizontal direction. The rotation angle detection module is fixed to the support and used for detecting the relative rotation angle of the support and the base. The laser ranging module is arranged on the support and used for measuring the spatial distance in the plumb line direction. According to the elevator space detection device, distance measurement is conducted in the horizontal direction through the arranged laser radar, distance measurement is conducted in the plumb line direction through the laser distance measurement module, and therefore various parameters of the space volume are obtained, and compared with the prior art that only area and distance measurement can be conducted, th
