Abstract
The utility model discloses a manual barring gear, comprising a barring gear handle, and a barring gear head. The barring gear handle can be automatically separated from the barring gear head; a shaft hole is provided in the middle of the barring gear head; the edge of the barring gear head is provided with a groove; the barring gear handle includes a hook-shaped handle head and a handgrip; the inner side of the barring gear handle is in close contact with the edge of the barring gear head; the hook-shaped handle head of the barring gear handle is matched with the groove provided at the edge of the barring gear head; and the hook-shaped handle head is buckled in the groove provided at the edge of the barring gear head. The manual barring gear provided in the utility model is safe and simple, and does not increase too much cost. The design is applied in the processes after a large-scale blower fan is assembled and before the practical running is carried out, and convenient and safe effect is achieved.
Description
Technical field
The utility model relates to handwheel, is specifically related to the handwheel that a kind of large fan is used.
Background technique
In the blower fan running of general occasion, only need before start, carry out manual jiggering, guarantee that the installation of equipment rotary component does not have to interfere, and guarantees the normal of equipment operation.
But the large fan running for industries such as power plant, iron and steel also needs to carry out manual jiggering after the start.Prior art is to pass the back by increasing the manual jiggering of the arm of force in the shaft extension section punching back of main shaft with very long steel pipe or round steel, there is very big potential safety hazard though the method is simple, after blower fan main shaft inertia rotates, steel pipe or round steel meeting transfer, turning radius is big, is easy to the people and the thing at scene are caused damage.
The model utility content
The model utility purpose: the utility model provides a kind of safe, easy handwheel in order to solve the deficiencies in the prior art.
The technical solution adopted in the utility model: a kind of handwheel, comprise the jiggering handle, the jiggering head, can separate automatically between described jiggering handle and the jiggering head, be provided with axis hole in the middle of the described jiggering head, described jiggering head edge is provided with groove, described jiggering handle comprises hook-shaped and handle at hand, described jiggering handle is inboard closely to be contacted with described jiggering head edge, jiggering handle hook-shaped matching with the groove at described jiggering head edge place at hand, hook-shaped in the groove that is buckled at hand on the described jiggering head edge.The jiggering head can break away from automatically with axle rotation hour indicator handlebar.
Described jiggering head is made as ratchet mechanism.
For making things convenient for the loading and unloading of jiggering head, the axis hole on the described jiggering head and the blower fan main shaft bearing section diameter of axle adopt loose fit; C type key is housed on the described jiggering head, and described jiggering head and C type key adopt loose fit.Utilize C type key to connect and transmit the jiggering moment of torsion, loose fit is also adopted in the key cooperation.Before the blower fan production run, jiggering head and key must be removed.
The length of described jiggering handle is 1-1.5 times of described jiggering head diameter.Long steel pipe can be welded in the scene on handle increase the arm of force.
Beneficial effect: the utility model handwheel, safe, simple and easy, can not increase too big cost.In the manual jiggering process of this design before large fan assembling back, production run, play the effectiveness of convenience, safety.

Embodiment
The utility model is described in further detail below in conjunction with embodiment: as Fig. 1, shown in 2, a kind of handwheel, comprise jiggering handle 1, jiggering head 2, can separate automatically between described jiggering handle 1 and the jiggering head 2, be provided with axis hole 3 in the middle of the described jiggering head 2, described jiggering head 2 edges are provided with groove 4, described jiggering handle 1 comprises hook-shaped 5 and handle 6 at hand, described jiggering handle 1 is inboard closely to be contacted with described jiggering head 2 edges, jiggering handle 1 hook-shaped at hand 5 and the groove 4 of described jiggering head 2 edges match, hook-shaped in 5 grooves 4 that are buckled on described jiggering head 2 edges at hand.
Described jiggering head 2 is made as ratchet mechanism.
The length of described jiggering handle 1 is 1.1 times of described jiggering head 2 diameters.
