Further, semiaxis is removably disposed on the support through attaching parts.
Further, semiaxis is a hollow shaft, and the end that hollow shaft stretches in the blind hole is provided with plug.
Further, be provided with bearing between semiaxis and the blind hole.
Further, bearing comprises: clutch shaft bearing is arranged between the sidewall and blind hole inwall of hollow shaft; Second bearing is arranged between plug and the blind hole inwall.
Further, the blind hole inwall is provided with step, and second bearing is arranged between the periphery wall of internal perisporium and plug of step.
Further, at least one carrying roller two ends is provided with stop lug.
Further, carrying roller is a nylon carrying roller.
According to the utility model on the other hand, a kind of hoisting crane is provided, has comprised rope supporting device, this rope supporting device is above-mentioned any rope supporting device.
Use the technical scheme of the utility model; Through being arranged side by side two carrying rollers up and down, between the carrying roller lateral wall, be formed for passing the horizontal slit of steel rope, because vertical direction is suppressed; Steel rope can't bob; And can only swing in the horizontal direction, thereby prevent that steel rope beating carrying roller from causing wearing and tearing, increased the service life of carrying roller.
Description of drawings
The Figure of description that constitutes the application's a part is used to provide the further understanding to the utility model, and illustrative examples of the utility model and explanation thereof are used to explain the utility model, do not constitute the improper qualification to the utility model.In the accompanying drawings:
Fig. 1 shows the front view according to the rope supporting device of prior art;
Fig. 2 shows the birds-eye view according to the rope supporting device of prior art;
Fig. 3 shows the semi-sictional view structural representation according to the rope supporting device of the embodiment of the utility model; And
Fig. 4 shows the left view according to the rope supporting device of the embodiment of the utility model.
The specific embodiment
Below with reference to accompanying drawing and combine embodiment to specify the utility model.Need to prove that under the situation of not conflicting, embodiment and the characteristic among the embodiment among the application can make up each other.
Like Fig. 3 and shown in Figure 4, the direction of arrow among the figure is the sense of motion of steel rope 50.According to the embodiment of the utility model, rope supporting device comprises support 30, rotating shaft and carrying roller 20.Its middle idler roller 20 central axis around the shaft is set in the rotating shaft rotationally, and rotating shaft is captiveed joint with support 30.The rotation of carrying roller 20 can realize through rotation around the shaft, also can realize through rotating shaft self is turned.Rotating shaft can be fixedly connected on the support 30, also can be arranged on rotationally on the support 30.
Dismounting for ease; The saving in material consumption alleviates rotating shaft weight simultaneously, and the semiaxis 10 of hollow is selected in rotating shaft for use; First end of semiaxis 10 is screwed onto on the support 30 through attaching parts 12, and second end of semiaxis 10 is provided with plug 11 and extend in the blind hole 21 that is arranged on carrying roller 20 end faces.In order to make carrying roller 20 stressed even, be provided with the semiaxis 10 of same structure and coaxial setting at the two ends of carrying roller 20.
For semiaxis 10 is cooperated with carrying roller 20 better, between semiaxis 10 and carrying roller 20, be provided with bearing 40, bearing 40 comprises the clutch shaft bearing 41 and second bearing 42.Clutch shaft bearing 41 is arranged between the internal perisporium of periphery wall and blind hole 21 of semiaxis 10, and near the outer face of carrying roller 20, and clutch shaft bearing 41 is fixed through bearing seat.Second bearing 42 is arranged between the internal perisporium of periphery wall and blind hole 21 of plug 11, limits second bearing 42 moving in axial direction through being arranged on convexity on the plug 11, thereby guarantees axial cooperation and the radial fit between semiaxis 10 and the carrying roller 20.
In order to make bearing 40 easier for installation, in blind hole 21, be provided with step with plug 11 corresponding positions, second bearing 42 is arranged between the periphery wall of internal perisporium and plug 11 of step.Setting through step in the blind hole 21 can make two bearings have different radiuses, therefore; When second bearing 42 is installed; Only need overcome the friction drag in the stepped hole, when clutch shaft bearing 41 is installed, only need overcome the friction drag of the entrance of blind hole 21; For two bearings of same radius, be convenient to Assembly &Disassembly more.
Another embodiment according to the utility model provides a kind of hoisting crane, comprises aforementioned any rope supporting device.
From above description, can find out that the utility model the above embodiments have realized following technique effect: through being arranged side by side two carrying rollers up and down; Between the carrying roller lateral wall, be formed for passing the horizontal slit of steel rope; Because vertical direction suppressed, steel rope can't bob, and can only swing in the horizontal direction; Thereby prevent that steel rope beating carrying roller from causing wearing and tearing, increased the service life of carrying roller.
The preferred embodiment that the above is merely the utility model is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
