Abstract
A portable belt clamping and pulling apparatus is provided to grip and pull belt ends together for splicing belt ends of a conveyor belt. A pair of belt ends are clamped between respective pairs of I-beams, the clamped belt ends are pulled together by a come-along mechanism, and the free ends of belt between the I-beams are maintained held together in a tension-free environment to allow fastening together of the belt ends. The preferred clamping jaws are in the form of at least one clamping lever pivotally mounted on a central frame having a central opening through which the I-beams are inserted. The clamping lever is connected to a pulling device that pivots the clamping lever to cause the clamping members to tightly grip a belt end between the I-beams. The clamping jaws include respective pre-tightening screws for clamping the I-beams to the belt prior to the initiation of pulling by the chains so as to eliminate slippage of the belt from between the I-beams during the initial pulling. The belt is gripped against slipping by being bent in a serpentine path between I-beam flanges of different width spans. Vertical guiding surfaces on frame walls defining the central opening are positioned adjacent respective forward and rear vertical surfaces of the I-beams to guide at least one of the I-beams for vertical translation and to limit torsional twisting and rotation of the I-beams. In one embodiment, one clamping member is supported on a stationary anvil on the frame while a piston is pushed against the other clamping member by a lever pivoted by the pulling device.
