Embodiment Construction

[0020] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

[0021] Such as figure 1 As shown, a lifting device 10 capable of self-locking and unlocking in a nuclear environment according to the present invention includes: a hanging beam 11 , a clamping mechanism 12 and a supporting base 14 . Two clamping mechanisms 12 are used to clamp the pallet fork 100 to replace the pallet fork 100 . The support base 14 is used to support the fork 100 from the bottom of the fork 100 to install the fork 100 . Two clamping mechanisms 12 are respectively arranged at two ends of the suspension beam 11 so as to clamp the fork 100 from both ends of the fork 100 so as to carry the fork 100 stably. The support base 14 is fixed to the fork 100 from the bottom of the fork 100 to support and install the fork 100 .

[0022] figure 2 and image 3 It further discloses the internal structure of the lifting device 10 ca...

Abstract

The invention discloses a hoisting device capable of self-locking and unlocking in a nuclear environment. The hoisting device comprises a hoisting beam, two clamping mechanisms and a supporting base; the clamping mechanism comprises a mounting seat, movable clamping plates and a guide shaft; the guide shaft is supported on the mounting seat; the two movable clamping plates are arranged on the periphery of the guide shaft in a sliding and sleeving manner; the mounting seat is also provided with two driving blocks, two driving gears and two connecting pieces; the two driving blocks are slidably connected to the mounting seat respectively and are provided with driving teeth; the two driving gears are rotationally connected to the mounting seat respectively and are engaged with the two driving teeth respectively; one ends of cranks of crank connecting rods are fixedly connected to the driving gears and the other ends are rotationally connected to one ends of connecting rods of the crank connecting rods; the other ends of the connecting rods of the two crank connecting rods are rotationally connected to the connecting pieces respectively; and the two connecting pieces are fixed to the two movable clamping plates respectively. According to the hoisting device capable of conducting self-locking and unlocking in the nuclear environment, stable carrying of pallet forks can be achieved, and the mounting positions of the pallet forks can be accurately positioned.

Description

technical field [0001] The invention relates to the field of hoisting cargo forks, in particular to a hoisting device capable of self-locking and unlocking in a nuclear environment. Background technique [0002] At present, manual lifting is usually used to replace the forks, and accidents such as pinching hands, dropping, and smashing feet often occur. The environment in the nuclear environment is complex, and there are safety risks in human labor. It is inconvenient and unsafe to replace the fork in the nuclear environment by using the above-mentioned replacement method. If the pallet fork is replaced by the crane and sling, due to the special site conditions of the nuclear environment, there is no suitable manual handling conditions, and the positioning accuracy of the crane and sling is very low, and there is a lot of shaking, so the assembly is more difficult. Contents of the invention [0003] At present, when the fork is tested in a nuclear environment, it is eithe...
