The invention discloses a braking device for maintenance of an underneath tractor type elevator, which comprises an elevator shaft and an underneath tractor type elevator body mounted in the elevator shaft, and threaded rods are mounted in the left side and the right side of the elevator shaft through bearings; the brake plate is welded to the side, close to the underneath traction machine type elevator body, of the linkage plate; the two movable plates are transversely arranged on the inner walls of the left side and the right side of the elevator shaft in a sliding manner respectively. According to the braking device for maintenance of the underneath traction machine type elevator, through the braking plates and the pressure-bearing blocks, when braking is needed, the threaded rods drive the triangular braking plates to be attached to the upper end and the lower end of the underneath traction machine type elevator body through the driving blocks and the linkage plates, and the electric push rods drive the pressure-bearing blocks to be attached to the side portions of the braking plates; and meanwhile, the stabilizing plate and the suction cup are driven to be tightly attached to the outer side of the underneath traction machine type elevator body, the braking stabilizing effect is enhanced, and the use safety is improved.

    本发明公开了一种下置曳引机式电梯维护时的制动装置,包括梯井以及安装在梯井内部的下置曳引机式电梯本体,所述梯井的左右两侧内部均轴承安装有螺纹杆;制动板,其焊接于连动板靠近下置曳引机式电梯本体的一侧;还包括:两个活动板,其分别横向滑动设置于所述梯井的左右两侧内壁。该下置曳引机式电梯维护时的制动装置,通过制动板和承压块,使得当需要进行制动时,螺纹杆利用驱动块和连动板带动三角形状的制动板贴合于下置曳引机式电梯本体上下两端,且电动推杆带动承压块贴合在制动板的侧部,从而制动板不易受力变形,延长使用寿命,同时带动稳固板和吸盘紧密贴合在下置曳引机式电梯本体的外侧,增强制动稳定效果,提高使用安全性。
