Title:
VALVE CONVEYING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/206646
Kind Code:
A1
Abstract:
Provided is a valve conveying apparatus comprising a bendable pipe (1), a withdrawing assembly (2), a traction wire (4), a bending adjustment rotating wheel (3), and a stabilizing pipe (5). The withdrawing assembly (2) is connected to the bendable pipe (1). The bending adjustment rotating wheel (3) is provided with a traction block (31). One end of the traction wire (4) is connected to the withdrawing assembly (2), while the other end is connected to the traction block (31). The stabilizing pipe (5) sleeves the bendable pipe (1) and is arranged between the withdrawing assembly (2) and the bending adjustment rotating wheel (3). The bending adjustment rotating wheel (3) is configured for adjusting the position of the traction block (31), and the traction block (31) drives the withdrawing assembly (2) to move by means of the traction wire (4) so as to adjust the bending degree of the bendable pipe (1). The stabilizing pipe (5) is configured for limiting the bending position of the bendable pipe (1). Therefore, the present invention features improved control precision of the bending shape of the valve conveying apparatus.
