The invention provides a brake device and a crane, the brake device comprises a first brake block and a second brake block, the first brake block and the second brake block are rotatably connected with a trolley frame of the crane and located between a first wheel and a second wheel, the first brake block is used for braking the first wheel, and the second brake block is used for braking the second wheel; the driving assembly is arranged on the trolley frame, located between the first wheel and the second wheel and connected with the first brake block and the second brake block so as to drive the first brake block and the second brake block to be switched between the braking state and the non-braking state. In the braking state, the driving assembly drives the first braking block to be close to the first wheel tread and drives the second braking block to be close to the second wheel tread, and braking of the first wheel and the second wheel is achieved through extrusion. In the non-braking state, the driving assembly drives the first brake block to be away from the first brake block tread and drives the second brake block to be away from the second wheel tread, and braking of the first wheel and the second wheel is relieved.
本申请提供了一种制动装置和起重机,制动装置包括:第一制动块、第二制动块,分别与起重机的台车架可转动连接,且位于第一车轮和第二车轮之间,第一制动块用于制动第一车轮,第二制动块用于制动第二车轮;驱动组件,设置于台车架且位于第一车轮和第二车轮之间,并与第一制动块和第二制动块相连,以能驱动第一制动块和第二制动块在制动状态和非制动状态之间进行切换;其中,制动状态下,驱动组件驱动第一制动块靠近第一车轮踏面,以及驱动第二制动块靠近第二车轮踏面,通过挤压实现对第一车轮和第二车轮的制动;在非制动状态下,驱动组件驱动第一制动块远离第一制动块踏面,以及驱动第二制动块远离第二车轮踏面,解除对第一车轮和第二车轮的制动。
