Problems solved by technology

[0008] However, the device cannot be used systematically in situations where the hydraulic actuator used is conventionally fixedly mounted relative to a portable support for the actuator
[0009] In this configuration, the hydraulic supply line of the actuator is necessarily fixed and, depending on the configuration used, encounters an obstacle arranged in the vicinity of the chain to be dismantled, which prevents the portable support of the actuator Placement of the device on the chain

Abstract

The invention proposes a device (10) for on-site installation and extraction of articulation shafts of links (14, 16) of large-sized chains having an alternating arrangement of outer links (14) and inner links (16) , each inner link (16) has two parallel side plates (20, 22) perforated at the ends (24, 26), and the two side plates pass through a tubular spacer (28) at the end (24 , 26) are joined together, and the two side plates are connected at the ends (24, 26) of the parallel side plates (20, 22) of the inner link (16) through the relevant hinge shaft (12) is hinged on the perforated ends (30, 32) of the parallel side plates (34, 36) of two successive outer chain links (14), the device (10) has at least one actuator (44) , the actuator is used to selectively actuate the end of a hinge shaft (12) or a side plate (34, 36) of an outer chain link (14) to insert or remove the hinge shaft, which It is characterized in that the apparatus comprises: a pair of portable actuator supports (46), which support two actuators (44) which move synchronously and pivotally; and a common actuator (44) Control device (48).

Description

technical field [0001] The invention relates to a device for on-site installation and removal of link articulation shafts of chains of large dimensions, in particular chains of conveyor belts in cement plants. [0002] The invention relates more particularly to a device for on-site installation and extraction of articulating shafts of links of large-sized chains, in particular of conveyor belts in cement plants, having so-called outer links and so-called Alternating arrangement of inner links, each inner link having at least two parallel inner plates perforated at their ends, said inner plates being closed at said ends by tubular spacers are joined together and said two inner plates are hinged at said ends of the parallel inner plates of said inner links to the perforated ends of the parallel outer plates of two successive outer links by means of associated hinge shafts In part, the device has at least one actuator, the device has: [0003] - at least one pair of portable ac...
