Description
Technical field:
The utility model relates to a kind of suspender that is used to be formulated in the hoisting heavy on hoisting crane or the similar devices, particularly relates to a kind of suspender that is used to overturn and/or loads and unloads roll bending.
Background technology:
The simplest member of suspender that is used for hoisting heavy is suspension hook and steel cable, use this kind structure suspender at overweight hollow articles such as handling such as roll bendings, need in advance roll bending manually to be tied up the back lifting with steel cable, though the suspender of this kind structure is simple, but use this kind suspender that even artificial compounding practice is arranged, use a suspender to overturn, and be linear contact component between steel cable and the roll bending object, as not being provided with protector, easily cause the damage of roll bending at connecting portion.
Use magnet lifting roll bending in this field also by common utilization, what adopt is exactly to utilize the lifting mode to load and unload roll bending to " the upright universal crane electromagnet that crouches " announced as Chinese patent 2440790, this suspender has the fixed magnetic pole and the detachable pole that is arranged in the horizontal T slot of fixed magnetic pole that cross-sectional plane is two right-angled trapezium, its meaning is to utilize active magnetic pole to improve the suction Beijing South Maxpower Technology Co. Ltd power of electromagnet, and the structure of utilizing right-angled trapezium makes things convenient for lifting plane or cambered surface weight, can the vertical or horizontal roll bending of lifting.Yet, electromagnet is to be attached to the lip-deep mode lifting of roll bending, for heavier object such as roll bending, need electromagnet that bigger volume will be arranged, so outside needing big exciting power output, also need crane that big lifting force is arranged, so in this case, be difficult to be provided with again tipping arrangement thereon.
The suspender that has jaw is to rely on lifting force that the mode that roll bending clamps is loaded and unloaded roll bending, what the name of announcing for No. 2122141 as Chinese patent was called " the pull-type tongs with pretension performance " employing is exactly that a kind of mechanical type clamps suspender, this suspender comprises a support body, and support body is provided with the stationary jaw and the movable jaw by the roll bending the put into outside face of suspension ring pull bar manipulation that can extend into roll bending middle part hollow part.When lifting, suspension ring pull bar pulling activity jaw clamps the back lifting so that it cooperates with stationary jaw with roll bending.But this kind suspender only is suitable for lifting vertical placement roll bending, and roll bending can not be overturn whole hanging in the process; And for the roll bending of horizontal placement, again stationary jaw is inserted after needing an artificial or additional suspender that it is tilted in roll bending hollow, lifting then, but roll bending is being hung upholder such as ground-surface moment, suspender will bear the very big tilting force effect of roll bending, under the effect of this power, cause suspender to shake consumingly, crane is damaged.
For weights such as roll bendings, though vertical placement is convenient to storage and transportation, but be unfavorable for that the end user processes it, as roll bending in uncoiling process, normally with its horizontal being placed on the decoiling unit, in the ordinary course of things, the uncoiling user can't the acquisition price costliness special-purpose turnup equipment, so manufacturer considers from making things convenient for user and self angle easy to loading and unloading, usually roll bending is transported in the mode of horizontal placement, and horizontal roll bending rolls easily, so in transportation, roll bending bottom must be provided with the backing plate close with its shape and more tie up articles for use as steel cable etc., bring many inconvenience to transportation, and cause the raising of its cost.
Summary of the invention:
Task of the present utility model provides a kind of suspender that utilizes automatic clamping and this dual mode hoisting heavy of arbitrary overturn.
The suspender of the hoisting heavy that the utility model proposed, have and be installed in a long element bottom and clamp assemblies that can move along the length direction of this long element, with the manipulation assembly that is used to drive described clamp assemblies action, and the switching mechanism that is installed in described long element top, this switching mechanism has one with the sprocket wheel that is driven by engine installation of hanging that element is connected be arranged on chain or steel cable on this sprocket wheel, and two elongated ends of described chain or steel cable are connected with clamp assemblies with an end regions of long element respectively
But described manipulation assembly comprise be installed in long element operating surface or in-to-in electrical motor and drive by this motor output shaft and have an externally threaded turning cylinder, at the sliding part that the band negative thread is installed on the turning cylinder and is complementary with outside thread on the turning cylinder.Long element is the hollow, rectangular body that a upper and lower is respectively arranged with microscler chute, the gear that electrical motor is connected with this motor output shaft is installed in the cuboid hollow part, and the driven gear that this gear and turning cylinder end are provided with is meshed, and the two ends that are installed in the sliding part on the turning cylinder extend in the described microscler chute and with described clamp assemblies and are connected.
Described clamp assemblies comprises the stationary jaw and the movable jaw that is connected with described sliding part that are arranged on the long element below, stationary jaw and the corresponding face of movable jaw are the inclined-planes of drawing close gradually from top to bottom, on each inclined-plane, be respectively arranged with and be similar to right-angled triangle or right-angled trapezium and make hypotenuse and the contacted slide block in inclined-plane at stationary jaw and movable jaw place, between contacted of stationary jaw and movable jaw and slide block, also be provided with needle roller or needle bearing, and in slide block, be provided with at the return mechanism that does not have to keep under the external force effect original position.
Described engine installation comprises electrical motor that is limited by bracing frame and the retarder that is connected with motor output shaft, and the output shaft of retarder directly is connected with sprocket shaft.
The two ends of described chain or steel cable are respectively arranged with rod member, and each rod member all flexibly connects with long element.
The switching mechanism that the suspender that the utility model proposed has adopted an electrical motor and retarder to constitute is because weight is realized upset again after lifting, so it does not need great power just it can be rotated; Simultaneously on two jaws, be provided with the slide block that can move down, this slide block is under the effect on jaw inclined-plane, when weight moves down by self geometric configuration or structure and with its automatic clamping, do not need to handle assembly big gripping power support is arranged, so it is not only safe and reliable in this suspender use, and structure is also simple relatively, and cost is also lower; In addition and since this suspender under the steering unit effect, may rotate to arbitrarily angled, so, can be suitable for hanging vertical type or horizontal roll bending.
