Shield support without front beam of shield support and withdrawing method

The invention discloses a shield support without a front beam of the shield support and a withdrawing method and relates to a shield hydraulic support and a withdrawing method by means of the shield support. The invention aims to solve the problem that an existing shield hydraulic bracket needs to be provided with the front beam of the shield support, which is large in weight and inconvenient to move. One end of a base is fixedly connected or hinged to one end of a shield beam connecting plate or a shield beam connecting rod, and the middle of the base is fixedly connected or hinged to the low end of a top beam hydraulic column; one end of the shield beam is hinged to the other end of the shield beam connecting plate or the shield beam connecting rod; the other end of the shield beam is hinged to one end of the top beam while the other end of the top beam is a top beam edge which is not connected to any devices, and the middle of the top beam is hinged to the top end of the top beam hydraulic column; the top
