Abstract
The utility model discloses a tyre crane chain installation tool which is provided for overcoming the defects that in the prior art, when a new chain is changed for the tyre crane, and the contacts at two ends of the chain are connected, the contacts need to be dragged with hands and carried on shoulders; and when bound ion wires are strung tightly, time and labor are consumed, the work efficiency is low, and insecurity exists. The utility model is characterized in that two ratchet wheels are oppositely fixed at two ends of a winding roller; pressure belt brackets and winding brackets, which cross over the winding roller and can rotate relative to the winding roller, are supported at the inner and outer sides of the two ratchet wheels; one end, which is away from the winding roller, of a pressure belt bracket is provided with a pulling belt the terminal tip of which is provided with a pulling claw capable of being hooked on the chain; a pulling belt terminal tip wound on the winding roller is also fixedly provided with a pulling claw; and a ratchet wheel pick installed on the winding bracket pokes the ratchet wheel to rotate, and wrenches the winding bracket manually repeatedly to wind the pulling belt on the winding roller, the distance between two pulling claws gradually is shortened until the two ends of the chain are connected together, and the chains is not needed to be dragged with hands and carried on shoulders. Thus, the installation tool has the advantages that the time and labor are saved, and the work efficiency is high; and people do not need to use a crowbar to twist the iron wires, thus the tyre crane chain installation tool is convenient and safe in use.
Description
Technical field
The utility model belongs to instrument, specifically a kind of instrument that is used to install the tyre crane cart chain.
Background technology
Tyre crane is the visual plant of harbour container loading and unloading, and tyre crane is loading and unloading container on the stockyard, and large vehicle walking is extremely frequent.The cart chain is the important component part of tyre crane cart running gear, is bearing all impacts that startup, operation, braking brought of large vehicle walking, is main consumable part, in order to guarantee the operate as normal of tyre crane, will in time change behind the chain wear.
When changing chain, the two ends of new chain need be hung over butt joint on the sprocket wheel.The butt joint of chain is installed, be with the mode that manually pulls pickaback at present, because the deadweight of cart chain is bigger, new chain length surplus is again little, often can not chain is stretching by artificial butt joint, dock very difficult, usually except that needs manually pull pickaback, also need to be through the two ends of chain, the two ends of iron wire are twisted into annular with iron wire, and then, make the two ends of chain progressively draw close the back butt joint with rotating in the crowbar insertion iron wire ring.The process need that reverses the tension iron wire repeats the two ends of chain are drawn close, entire work process is usually got off the maintenance personal is made oil stain all over the body, dog-tired, consuming time many, consumption power is big, inefficiency, therefore changing chain is that a not only dirty but also tired hard and unprofitable job makes, and always all is the relatively work of headache of maintenance personal;
Moreover, need overcome the bigger tensile force of chain during owing to butt joint, when turning round iron wire with crowbar, iron wire is often broken suddenly, easily the maintenance personal is damaged, and safety can not get ensureing.
The utility model content
Technical problem to be solved in the utility model is, overcome the prior art tyre crane cart and more renew chain, when the joint at chain two ends is connected, need by manually pulling pickaback, and the iron wire that tightens up binding docks, take time and effort, the low and unsafe shortcoming of work efficiency provides a kind of tyre crane cart chain erecting tools.
In order to solve the problems referred to above that prior art exists, the utility model is to adopt following technical proposals to realize: in the two ends of take-up roller relative fixed two ratchets are arranged, be positioned at the inside and outside both sides of two ratchets, stride take-up roller respectively and be supported with the pressure zone support and the winding support that can rotate relative to take-up roller, the pressure zone support from take-up roller one end drawstring is installed, the termination of drawstring has the pulling claw that can collude on chain, the drawstring termination that twists on the take-up roller also is fixed with pulling claw, by the torque spring pretension, can insert the ratchet plectrum between hook tooth, be installed in the plectrum guide groove of winding support both sides.
The utility model also has following technical characterictic:
Described take-up roller is made up of two semicircle axles that two ends are fixedly mounted on the two ratchets wheel sheet, its middle spacing can be inserted drawstring;
Be provided with the washer guide groove of subtend take-up roller center position in the both sides of described pressure zone support, be equipped with in the groove with the compression spring and be supported on the pressure zone support, can insert the washer between two hook tooths;
Be installed in the ratchet plectrum of described winding support both sides, it is provided with plectrum from take-up roller direction one end and lifts handle, on described winding support, the termination that is positioned at the take-up roller side is provided with cam; On described drawstring support, be positioned at the side of being provided with, the termination tooth of take-up roller side; When winding support and drawstring support turn on take-up roller when being in relative position, the both sides of described ratchet plectrum are inserted between the ratchet of two ratchets, the both sides of described washer are on the salient point of described cam simultaneously, and the both sides of described ratchet plectrum are inserted in the square tooth of described drawstring support termination;
Described winding support from take-up roller direction one end, the handgrip that conveniently lifts is installed.
When needs are installed new chain, the new chain that to change earlier hangs on the sprocket wheel, with described pulling claw on the take-up roller and the described pulling claw on the pressure zone support, collude two terminations respectively at chain, two hands are held pressure zone support and pressure zone support respectively, back of tooth bevel direction along ratchet is pulled the winding support, the ratchet plectrum that is installed in winding support both sides slips over a tooth from the back of tooth of ratchet, pull the winding support more in the other direction, the ratchet plectrum is stirred ratchet and is rotated a tooth, drive drawstring simultaneously and be wound on pairing drawstring one segment length of tooth angle degree on the take-up roller, repeat aforesaid operations, two drawstring pulling claws will be close gradually, and the two ends of chain is connected together the most at last.
Advantage of the present utility model and good effect are, because the two ends of described take-up roller are fixed with ratchet, and be supported with the pressure zone support and the winding support that can rotate relative to take-up roller, on the pressure zone support on the pulling claw of drawstring and the take-up roller pulling claw of drawstring can collude two ends respectively at chain, the ratchet plectrum is installed on the winding support and can inserts between hook tooth, pull the winding support repeatedly with hand, drive the ratchet plectrum and dial the ratchet commentaries on classics, drawstring is wound on the take-up roller, shortens the distance of pulling claw on two drawstrings gradually, be connected together until the chain two ends, manually do not pull the big chain of weight pickaback, time saving and energy saving, work easily, good work environment, high efficiency; Do not need the human crowbar to turn round iron wire yet, safe and convenient to use.
