Abstract
The utility model relates to a self-locking reeving machine, comprising a frame, a multispeed motor, a shaft coupler, a reversing reducer, a rack wheel, a pinion and a reeving box. The reeving box is disposed above the frame. A rack wheel and two pinions are disposed on the reeving box. A plurality of reeving racks are disposed above the rack wheel and the pinions. The reeving rack is provided with a cable pulley having tooth and a reeving cable pulley having tooth. The reeving cable pulley and the reeving rack are connected via a board in order to efficiently form self-locking when a steel strand is crossed through the reeving machine. The utility model has compact structure, convenient operation, high speed and stable property.
Description
Technical field: the utility model relates to a kind of cable machine, particularly relates to a kind of prestressed concrete steel strand self-locking cable machine that uses under the backward pull method occasion that is used in.
Background technology: along with the high speed development of Chinese national economy, large quantities of high-speed railways, intercity high ferro, bridge spanning the sea, large bridge, the three-dimensional bridge of speedway, large foundation construction such as nuclear power station start in succession, and in these large-scale construction, all need a large amount of use prestressed concrete steel strand, and when using the prestressed concrete steel strand, generally all adopt post stretching, just the reinforced cement concrete goods after prefabricated are carried out stretch-draw anchor by the steel strand that pierce into, to eliminate concrete prestressing force, improve the strength and stiffness of concrete products, at this moment just need to adopt a large amount of cable machines, and the cable machine that generally adopted in the past, all be that pair roller applies normal pressure, make it form malleation frictional force, thereby make the tightwire wire motion, though this design can the extended steel twisted wire, but fixing in being difficult to steel strand are moved, inefficiency can not satisfy demand of practical production.
Summary of the invention: the purpose of this utility model is exactly the self-locking cable machine that a kind of novelty will be provided, and it can overcome the existing defective of above Vintage Product effectively.The purpose of this utility model is to realize like this, the self-locking cable machine, formed by frame, multispeed electric machine, shaft joint, communtation deceleration device, gear wheel, pinion, the casing of reeving, it is characterized in that: described multispeed electric machine is arranged on the below of frame, and shaft joint links together communtation deceleration device and multispeed electric machine; Above frame, be provided with the casing of reeving, casing is provided with gear wheel and two pinions, above big pinion, be provided with several and can put the frame of reeving, the described frame of reeving of putting is provided with toothed wheel and the toothed wheel of reeving of putting of reeving, can put reeve frame with can put the employing junction plate of reeving between the frame and be connected.
The utility model is simple in structure, and is easy for installation, can overcome the existing problem of Vintage Product effectively.

The specific embodiment: the utility model is described in further detail below in conjunction with accompanying drawing
In Fig. 1, the utility model self-locking cable machine, formed by frame, multispeed electric machine, shaft joint, communtation deceleration device, gear wheel, pinion, the casing of reeving, it is characterized in that: described multispeed electric machine is arranged on the below of frame, and shaft joint links together communtation deceleration device and multispeed electric machine; Above frame, be provided with the casing of reeving, casing is provided with gear wheel and two pinions, above big pinion, be provided with several and can put the frame of reeving, the described frame of reeving of putting is provided with toothed wheel and the toothed wheel of reeving of putting of reeving, can put the frame of reeving adopts junction plate to be connected with can putting to reeve between the frame. when specifically implementing, multispeed electric machine is connected with the communtation deceleration device by shaft joint, the communtation deceleration device is delivered to power on the gear wheel through adhesive tape, and gear wheel is delivered to power respectively on two pinions; On the casing of reeving, operated by rotary motion has four groups can put the frame of reeving, can put the frame of reeving for every group and be provided with a toothed wheel and the toothed wheel of reeving of putting of reeving, the axle of taking turns of reeving is fixed on the casing of reeving, toothed put reeve the wheel can be the left and right swing in center with the wheel shaft of reeving, and four groups can to put the frame of reeving be to be connected with junction plate, so four groups can be put the frame of reeving and form an interlock body of swing synchronously by junction plate; When tightwire wire pierces into from advancing Suo Kou, by by four groups reeve the wheel with can put reeve the wheel formed the steel strand passage time, power on two pinions drives respectively and is arranged on the wheel rotation forward of reeving of the band tooth that can put on the frame of reeving, the wheel of reeving is equivalent to decide roller, be equivalent to moving roller and can put the wheel of reeving, moving roller is the center with the axle of deciding roller, can be around deciding the roller swing. when fixed, when moving roller rotates synchronously, steel strand produce frictional force to moving roller, steel strand begin to travel forward, drive moving roller simultaneously along the swing of steel strand travel direction, thereby steel strand to be exerted pressure. the linear velocity of steel strand is fast more, the power of moving pair of rollers steel strand effect is just big more, self-lock force is also just big more, interact between steel strand and the moving roller, keep moving roller and steel strand and decide being synchronized with the movement of roller, it between them the interactively that under dynamic action, forms under the self-locking locking state, so as dynamic end is that self-locking state disappears. when steel strand, as long as start motor, four groups of wheels of reeving will be worked immediately, the limit is entered the steel strand limit and is formed self-locking, steel strand can reach per minute conveyer line speed and reach more than 120 meters. when steel strand need retreat, adjust lock bolt, steel strand can withdraw from from cable machine. the utility model compact conformation, easy to operate, fast, stable performance.
