Abstract
Described herein are examples of chain pullers, which may include a first arm, a second arm, a first linkage, a second linkage, and an actuator. The first arm may include a linkage end and an engagement end. The second arm may include a linkage end and an engagement end. The first linkage may include a proximal end connected to the first arm and a distal end connected to the second arm. The second linkage may include a proximal end connected to the first arm and a distal end connected to the second arm. The actuator may have a first end connected to the first arm and a second end connected to the second arm. The first arm, the second arm, the first linkage, the second linkage, and the actuator may be configured such that when the actuator is actuated, a distance between the engagement ends is changed.
Claims23
A chain puller apparatus, comprising:
- a linkage subsystem having a first engagement end and a second engagement end, the linkage subsystem comprises:
- a first arm including a first linkage end and a first engagement end;
- a second arm including a second linkage end and a second engagement end;
- a first linkage including a first proximal end connected to the first arm and a first distal end connected to the second arm;
- and
- a second linkage including a second proximal end connected to the first arm and a second distal end connected to the second arm;
- an actuation subsystem, the actuator subsystem comprises:
- an actuator having a first end connected to the first arm and a second end connected to the second arm, the actuator comprises a hydraulic piston actuator, a pneumatic piston actuator, and a linear electric actuator;
- a connection line coupled to the actuator, the connection line comprises a hydraulic hose, a pneumatic hose;
- and one or more wires;
- and
- an external driver coupled to the connection line, the external driver is a hydraulic pump, a pneumatic pump, and an electronic controller;
- wherein the linkage subsystem and the actuator subsystem are configured such that when the actuator subsystem is actuated, a distance between the first engagement end and the second engagement end is changed;
- wherein the first arm, the second arm, the first linkage, the second linkage, and the actuator subsystem are configured such that when the actuator subsystem is actuated, a distance between the first engagement end and the second engagement end is changed;
- and
- wherein the electronic controller comprises a machine interface, a machine control unit, a control panel, and a switch
A chain puller apparatus, comprising:
- a linkage subsystem having a first engagement end and a second engagement end;
- and
- an actuation subsystem;
- wherein the linkage subsystem and the actuator subsystem are configured such that when the actuator subsystem is actuated, a distance between the first engagement end and the second engagement end is changed.
A method, comprising:
- providing a chain puller device, the chain puller device comprises:
- a linkage subsystem having a first engagement end and a second engagement end;
- and
- an actuation subsystem;
- running a conveyor to a desired position, the conveyor comprising a conveyor chain, the conveyor chain having a normal tension and a relaxed tension;
- engaging the chain puller to the conveyor chain;
