Embodiment Construction

[0022] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings to describe the technical solution of the present invention in detail.

[0023] figure 1 and figure 2 It is a structural schematic diagram of the pin shaft installation and withdrawal and the locking and unlocking states of the locking device. This device is made up of pin shaft 1, nut 2, pull rod 3 and locking device 4. The head of the tie rod 3 has external threads, and the end of the pin shaft 1 has internal threads. The nut 2 and the pin shaft 1 are threaded on the pull rod 3 at the same time. The connection of pull rod 3 is firm and not easy to loosen. The pull bar 3 is provided with an open baffle 8, a pinned baffle 11 and a handle 12, all of which are connected by welding. The locking device 4 is provided with an inner lock plate 9, an outer lock plate 10, a handle 13, a locking bolt 14, a synchronous shaft and a baffle plate 15, and the like. Th...

Abstract

The invention discloses a pin roll mounting, retreating and locking device, which comprises a pull rod, one or more than one locking baffle plate and one or more than one lock plate, wherein, one endof the pull rod is connected with the pin roll; one or more than more pin locking baffle plate is fixed on the pull rod; and one or more than one lock plate makes the locking baffle plate and the position where the pin roll is positioned connected and fixed with each other. The pin roll mounting, retreating and locking device can realize the mounting, retreating and locking of the pin roll in theinside of a harsh environment, a narrow space or a complex structure at a long distance.

Description

technical field [0001] The invention relates to the fields of heavy machinery and metallurgical machinery, in particular to a pin mounting, withdrawing and locking device. Background technique [0002] In harsh environments, narrow spaces or complex structures, the loose pin shaft connection width needs to be frequently tightened and loosened, especially when the shafts used in it are pinned and loosened, usually the operator must be in a harsh ring tight or narrow space Inside or open a craft hand hole, use tools to knock, and lifting tools to cooperate to realize the work of loading or unwinding the shaft. Its operation is complicated and inconvenient to carry out. Contents of the invention [0003] The purpose of the present invention is to provide a pin shaft installation, withdrawal and locking device that can realize long-distance installation, withdrawal and locking of the pin shaft in the above-mentioned environment. [0004] The purpose of the present invention ...
