Description
Technical field
The utility model relates to a kind of releasing pulley.
Background technology
Releasing pulley is to be applied in electric power, the construction trade, the accessory appliances of using when being used to lift weight or pipeline installation.Use releasing pulley to lift weight or pipeline installation, have easy to operate, increase work efficiency and reduce the effect of pipeline degree of injury, application is very extensive in industries such as electric power and building.At present, the releasing pulley of conventional confguration generally comprises the support that pulley is housed, and also is provided with on the support and extraneous bonded assembly installation portion.Different according to principle of work, installation portion can be divided into hook-hang type and holding.The advantage of hook-hang type installation portion is easy for installation, only needs hook mounted in the knock hole of external support component to get final product, and resistance to overturning was poor when shortcoming was work, was prone to rock, and caused Psychological Panic easily.The holding installation portion mainly is through attaching partss such as bolts; Support is fixedly installed on the external support components such as bracing frame or electric pole cross-arm, advantage be install firm, shortcoming be need install one by one with instruments such as spanners, demounting bolt; Operation is trouble, has a strong impact on work efficiency.
Summary of the invention
The technical matters that the utility model will solve is to provide a kind of rational in infrastructure to above-mentioned deficiency, and quick, convenient disassembly are installed, and it is time saving and energy saving to operate, and firm a kind of releasing pulley is installed.
For solving the problems of the technologies described above; This releasing pulley comprises the support that pulley is installed, and also is provided with on the support and extraneous bonded assembly installation portion, and its constructional feature is: said installation portion comprises horizontal support plate and the perpendicular support plate that vertically is fixed together; Be hinged with yoke plate on the support plate in horizontal support plate and the perpendicular support plate to another support plate swing; Another support plate is provided with and the cooresponding draw-in groove of yoke plate, and the yoke plate end is connected with double-screw bolt, tightens the jam nut that yoke plate is locked at draw-in groove on the double-screw bolt.
The releasing pulley of this structure be through the cluster locking mechanism realize installing fast, convenient disassembly, it is time saving and energy saving to operate, and install firm.
The cluster locking mechanism mainly comprises horizontal support plate and the perpendicular support plate that is installed on the support, and horizontal support plate is horizontally disposed with, and perpendicular support plate vertically is provided with, and horizontal support plate is fixed together with perpendicular support plate is vertical.Like this, just constituted the screens groove at a band right angle between the adjacent wall of horizontal support plate and perpendicular support plate, therefore can be used with extraneous erecting frame with right angle.Present electric pole cross-arm all is to adopt angle steel directly to cut out to cut to form, and therefore, can very like a cork the horizontal support plate and the perpendicular support plate of this releasing pulley be withheld on the electric pole cross-arm.Be hinged with yoke plate on the support plate in horizontal support plate and the perpendicular support plate, yoke plate can support plate be to another support plate swing from the place around its hinge, and the support plate that yoke plate is flapped toward is provided with and the cooresponding draw-in groove of yoke plate.Like this, when yoke plate was flapped toward this support plate, horizontal support plate, perpendicular support plate and yoke plate had just surrounded a cavity that cross-sectional plane is a right-angled triangle, and this cavity is that splendid attire electric pole cross-arm provides the space.The yoke plate end is connected with and the cooresponding double-screw bolt of draw-in groove, and double-screw bolt is provided with jam nut.The main effect of jam nut is when double-screw bolt is swung in the draw-in groove, is screwed on the double-screw bolt and with double-screw bolt from the double-screw bolt end to be locked at draw-in groove place support plate, and at this moment, horizontal support plate, perpendicular support plate and yoke plate also just have been fixed in together.When reality is used; Earlier jam nut is unclamped from double-screw bolt, then double-screw bolt and yoke plate are shown in draw-in groove, and double-screw bolt and yoke plate are outwards launched; Make double-screw bolt, yoke plate, horizontal support plate and perpendicular support plate opening-like; Right angle draw-in groove correspondence with horizontal support plate and perpendicular support plate formation snaps fitted on the electric pole cross-arm again, and then yoke plate and double-screw bolt are oppositely put back, and double-screw bolt is swung in the draw-in groove; Tighten jam nut at last, can this releasing pulley be fixed on the electric pole cross-arm through yoke plate, double-screw bolt, horizontal support plate and perpendicular support plate.The triangular structure of this releasing pulley through having horizontal support plate, perpendicular support plate and yoke plate to surround realizes the captive joint between releasing pulley and the line bar cross-arm, connects firmly, and reliable lock helps to improve safety in utilization.When needing dismounting, only need unscrew jam nut, can this releasing pulley be disassembled from line bar cross-arm.No matter installation is still dismantled, and operates all very simply, and people just can operate, and helps to increase work efficiency.
As improvement, the pulley quantity of installing on the support is at least two, the coaxial setting of pulley room.
The pulley quantity of installing on the support is set at least two, can lay at least two cables simultaneously, helps to improve laying efficient.Pulley coaxle is provided with, and can improve the global symmetry of releasing pulley, helps to strengthen the stability in use of releasing pulley.
As further improvement, be installed with handwheel on the jam nut.
Handwheel is set on jam nut, and directly hand-tight make-up or pine are unloaded jam nut, more convenient operation, and more laborsaving.
As further improving, the support upper articulation has the protective cover that pulley top is covered again, and the protective cover other end is provided with positioning groove, is installed with the screw rod that cooperates with positioning groove on the support, tightens on the screw rod protective cover is fixed on the setscrew nut on the support
Protective cover is set on support, can plays the effect of the circuit that prevents on pulley slippage from the releasing pulley, guaranteed the functional reliability of this releasing pulley.Protective cover is rack-mount through articulated manner, provides convenience for opening and closing protective cover.The protective cover other end through with support on the screw rod positioning groove and the setscrew nut that cooperate, can protective cover be fixed on the support, reliability of service is higher.
In sum, adopt the releasing pulley of this structure, rational in infrastructure, install fast, convenient disassembly, it is time saving and energy saving to operate, and installs firmly, is particularly suitable in power industry, using.
