Abstract
The utility model discloses a hauling rope winding structure of a main trolley of a crane. The structure comprises four fixed pulleys fixed to the main trolley of the crane, wherein the four fixed pulleys are divided into two sets and are arranged in parallel and at intervals, the two fixed pulleys of each set are located on the same straight line, the two sides, corresponding to the two sets of fixed pulleys, of the main trolley of the crane are respectively provided with two head redirection pulleys and two tail redirection pulleys, one side, provided with the tail redirection pulleys, of the main trolley of the crane is further provided with a traction winding drum, and two traction ropes respectively and sequentially pass through the fixed pulleys, the head redirection pulleys, the traction winding drum and the tail redirection pulleys and then are connected through two wire clamps. The hauling rope winding structure of the main trolley of the crane has the advantages of being stable and reliable in operation and large in traction force.
Description
Technical field
The utility model relates to a kind of hoisting crane, relates in particular to a kind of hoisting crane main carriage hauling rope wiring structure.
Background technology
Hoisting crane belongs to a kind of of elevator machinery, is a kind of machinery of making circulation, intermittent moment.A working cycle comprises: load-engaging device is mentioned article from getting thing ground, then is moved horizontally to appointed place and falls article, then carries out counter motion, makes the load-engaging device reposition, in order to circulate next time.
Hoisting crane main carriage hauling rope wiring is the pith on hoisting crane, and it directly determines the stability of main carriage operation and the size of main carriage tractive force.The main carriage traction ubiquity operation stability of existing hoisting crane is poor, the shortcoming that tractive force is little.
The utility model content
The purpose of this utility model is to provide a kind of hoisting crane main carriage hauling rope wiring structure, and it has stable and reliable operation and the large characteristics of tractive force, to solve the problem that in prior art, hoisting crane exists.
For reaching this purpose, the utility model by the following technical solutions:
A kind of hoisting crane main carriage hauling rope wiring structure, it comprises four dead sheaves that are fixed on the hoisting crane main carriage, these four dead sheaves are divided into two groups of parallel interval and arrange, two pulleys of every group of pulley are located along the same line, corresponding every group of pulley is respectively arranged with two head changed course pulleys and two afterbody changed course pulleys in the both sides of hoisting crane main carriage, the side that described hoisting crane main carriage arranges afterbody changed course pulley also is provided with hitch wheel, two hauling ropes are walked around respectively dead sheave successively, head changed course pulley, hitch wheel is connected by two wire clamps with after afterbody changed course pulley.
Be provided with several carrying rollers between dead sheave and head, afterbody changed course pulley on described two hauling ropes.Be provided with tightening device on position near afterbody changed course pulley on described two hauling ropes.
The beneficial effects of the utility model are, compared with prior art on two steel ropes of described hoisting crane main carriage hauling rope wiring structure, be provided with carrying roller, guaranteed the stable of traction system, being provided with tightening device can be regulated the tension force of hauling rope simultaneously, make the tension force between hauling rope and pulley be in all the time comparatively suitable coupling, improved tractive force.
The accompanying drawing explanation
Fig. 1 is the structural representation of the hoisting crane main carriage hauling rope wiring structure that provides of the utility model specific embodiment 1.
The specific embodiment
Further illustrate the technical solution of the utility model below in conjunction with accompanying drawing and by the specific embodiment.
Refer to shown in Fig. 1, Fig. 1 is the structural representation of the hoisting crane main carriage hauling rope wiring structure that provides of the utility model specific embodiment 1.
In the present embodiment, a kind of hoisting crane main carriage hauling rope wiring structure comprises four dead sheaves 2 that are fixed on hoisting crane main carriage 1, these four dead sheaves 2 are divided into two groups of parallel interval and arrange, two pulleys 2 of every group of pulley are located along the same line, corresponding every group of pulley is respectively arranged with two head changed course pulleys 3 and two afterbody changed course pulleys 4 in the both sides of hoisting crane main carriage 1, the side that described hoisting crane main carriage 1 arranges afterbody changed course pulley 4 also is provided with hitch wheel 5, two hauling ropes 6 are walked around respectively dead sheave 2 successively, head changed course pulley 3, hitch wheel 5 is connected by two wire clamps 7 with after afterbody changed course pulley 4.Be provided with several carrying rollers 8 between dead sheave 2 and head changed course pulley 3 and afterbody changed course pulley 4 on described two hauling ropes 6.To have guaranteed the stable of traction system.
Be provided with tightening device 9 on position near afterbody changed course pulley 4 on described two hauling ropes 6, regulate tightening device 9, make the tension force between hauling rope and pulley be in all the time comparatively suitable coupling, improved tractive force.
Above embodiment has just set forth groundwork of the present utility model and characteristic; the utility model is not limited by above-mentioned example; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various variations and change, and these variations and change all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
Claims (3)
