Abstract

The present invention relates to the technical field of escape knapsack slow lowering, in particular to a tower crane emergency escape self-rescue knapsack type slow lowering device and a method of use thereof. The lower end of the main body is provided with a capstan, the right end of the capstan is provided with a slow-down assembly, the right end of the capstan is provided with a locking assembly, and the tightening assembly includes straps, and there are two straps in a left-right symmetrical structure. The present invention facilitates the slow lowering and fast locking of the main body of the backpack through the use of the slow-down assembly and the locking assembly, and inserts the push rod of the emergency stop assembly into the positioning hole, thereby improving the controllability of use and realizing different The user provides different descending speeds, the adjustment is convenient and quick, and the good slow-down effect is improved. After an accident or slow-down failure, it can be locked in time, avoiding the occurrence of secondary accidents, and protecting the safety of users. The safety and reliability are significantly improved, and the use effect is good.

Description

technical field [0001] The invention relates to the technical field of escape knapsack slow lowering, in particular to a tower crane emergency escape self-rescue knapsack type slow lowering device and a use method thereof. Background technique [0002] Tower crane is the most commonly used lifting equipment on construction sites, also known as tower crane. The last indispensable equipment, the function of the tower suspension tip is to bear the upper load transmitted by the jib stay rope and the balance jib stay rope, and transmit it directly to the Tower body structure, self-elevating tower top has truncated cone column type, forward or backward inclined truncated cone column type, herringbone frame type and diagonal brace type. [0003] The emergency escape bag is a bag containing items needed in an emergency. When a disaster occurs and you need to escape quickly, you can carry it on your back. If you escape from the balcony, window and other exits, you can often escape f...
