Abstract
A bi-directional adjustable chain ratchet wheel tensioner is formed by a chain tensioner, a chain and an adapter ring in a connecting mode. Parts of the bi-directional adjustable chain ratchet wheel tensioner are formed by precision casting and mechanical stamping. The bi-directional adjustable chain ratchet wheel tensioner is characterized in that the chain tensioner is composed of a connecting plate, a ratchet wheel, a chain wheel shaft, a pawl, a pawl shaft, a joint, a pin roll, a regulating ring, a rubber plug, a guiding tube, a riveting shaft and a spring; the connecting plate is of a U type, the chain wheel shaft is mounted inside the connecting plate, the ratchet wheel is mounted on the chain wheel shaft, and the pawl is mounted on the pawl shaft and is matched with the ratchet wheel; the guiding tube and the riveting shaft is fixed with the connecting plate and the chain wheel shaft, and the regulating ring, the joint and the connecting plate are sequentially connected; and the regulating ring is of a U type, the middle of the regulating ring protrudes to be of a circular shape, the ends of the regulating ring are of a circular shape, and round through holes are arranged in the middles of the ends. One end of the chain is wound on the chain wheel shaft, the end of the chain is connected and fixed by a connecting ring used for the end portion and the chain, the other end of the chain is connected with the regulating ring, a middle circular hole of the regulating ring is sealed by the rubber plug, and the end of the chain is connected and fixed by a connecting ring used for the end portion and the chain. The chain is adjusted to be in moderate elasticity, a specially-used wrench is used for rotating the chain wheel shaft to tension the chain, and so that the functions of tensioning, binding and reinforcing are achieved. The bi-directional adjustable chain ratchet wheel tensioner is suitable for binding and reinforcing of heavy machinery, wheel-type equipment and track-type equipment in railway transpiration.
Description
Technical field
The utility model relates to the binding of railway transportation goods and reinforces equipment, is that rigging is reinforced in a kind of novel binding, is applicable to that the binding of the medium and heavy machinery of railway transportation, wheeled equipment and caterpillar type equipment is reinforced.
Background technology
At present, in the middle of the China Railway industry, the 8# that the binding reinforcing aspect that wheeled equipment is transported generally adopts has galvanized iron wire or adopts steel rope to join the wire clips binding and reinforce, complex operation, time-consuming, effort, loading and unloading are on-the-spot mixed and disorderly, and poor stability, very easily the generation binding is become flexible and can't be fastening, has many potential safety hazards.
Summary of the invention
In order to overcome the shortcoming and defect of existing railway transportation Goods binding reinforcement means, the utility model provides a kind of bi-directional adjustable chain straining ratchet, and this binding rigging is not only simple to operate, economical and practical, and easy to use, convenient power-saving, safe and reliable.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of bi-directional adjustable chain straining ratchet is to be formed by connecting by chain strainer, chain, coupling link, and its parts adopt precision cast, mechanical stamping to form; It is characterized in that described chain strainer is by connecting panel, ratchet, sprocket shaft, ratchet, pawl axis, joint, bearing pin, regulating ring, plug, guide pipe, riveted joint axle, spring is formed; Connecting panel is the U type, and sprocket shaft is installed in the connecting panel, and ratchet is installed on the sprocket shaft, and ratchet is installed on the pawl axis and cooperates with ratchet, guide pipe, riveted joint axle fixed connecting plate and sprocket shaft; Regulating ring, joint, connecting panel are linked in sequence; Wherein regulating ring is the U type, and middle protrusion is rounded, and rounded centre, termination is a round tube hole.Chain one end is on sprocket shaft, and the end is connected and fixed the chain termination with coupling link and chain; The chain other end is connected with regulating ring, and plug is sealed the middle circular hole of regulating ring, and the end is connected and fixed the chain termination with coupling link and chain.Adjust chain degree of tightness appropriateness,, thereby play the effect that the tension binding is reinforced with special wrench rotating sprocket axle tension chain.
The utility model has following actively useful effect:
Simple in structure, easy to use, tensile strength is big, safe and reliable.
