Abstract
The utility model relates to a kind of lifting appliances, a kind of specifically automatic lockout suspension hook, including hook and self-locking platform sling, the hook includes mounting plate and coupler body, mounting plate is equipped with connecting shaft, the self-locking platform sling is rotatably mounted in connecting shaft, and when the upper end of self-locking platform sling is sling by lifting loop chain, the lower end of self-locking platform sling is in contact with the end of coupler body.The pulling force of the utility model lifting and the power of locking act on self-locking platform sling simultaneously, make to lock always when lifting, structure is simple, and manufacturing cost is low, and stability is high, highly-safe.
Description
Technical field
The utility model relates to a kind of lifting appliance, a kind of specifically automatic lockout suspension hook.
Background technique
In the prior art, the locking protection of suspension hook stops workpiece to go out to skid off from suspension hook using latch plate, with spring
After access times increase spring life reach after fail, manually not in time replacement spring cause workpiece have in hoisting process draw
Hidden danger out.
Summary of the invention
The utility model aims to solve the problem that the above problem, provides a kind of automatic lockout suspension hook, without using spring, provides steady
Qualitative and safety.
According to the technical solution of the utility model, the automatic lockout suspension hook, including hook and self-locking platform sling, the hook
Including mounting plate and coupler body, mounting plate is equipped with connecting shaft, and the self-locking platform sling is rotatably mounted in connecting shaft, self-locking to hang
When the upper end of plate is sling by lifting loop chain, the lower end of self-locking platform sling is in contact with the end of coupler body.
Further, the self-locking platform sling is rotatably mounted in connecting shaft using self-lubricating copper sheathing.
Further, the pressing plate for limit self platform sling is installed in the connecting shaft.
Further, the upper end of the self-locking platform sling is provided with through-hole, and the lower end of self-locking platform sling is provided with close to the side of coupler body
Notch.
Further, the coupler body is the U-shaped being laterally arranged.
The utility model has the beneficial effects that: the pulling force of lifting and the power of locking act on self-locking platform sling simultaneously,
Make to lock always when lifting, structure is simple, and manufacturing cost is low, and stability is high, highly-safe.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the left view of Fig. 1.
Description of symbols: 1- self-lubricating copper sheathing, 2- pressing plate, the self-locking platform sling of 3-, 4- connecting shaft, 5- hook, 5.1- installation
Plate, 5.2- coupler body, 6- lifting loop chain.
Specific embodiment
The utility model is described in further detail with attached drawing combined with specific embodiments below.
It is as shown in the figure: automatic lockout suspension hook, including hook 5 and self-locking platform sling 3.Wherein, hook 5 includes 5.1 He of mounting plate
The coupler body 5.2 being fixed on mounting plate 5.1 is equipped with connecting shaft 4, self-locking 3 company of being rotatably mounted to of platform sling on mounting plate 5.1
In spindle 4.When the upper end of self-locking platform sling 3 is sling by lifting loop chain 6, self-locking platform sling 3 rotates, the end of lower end and coupler body 5.2
Portion, which is in contact, realizes locking.
Specifically, self-locking platform sling 3 is rotatably mounted in connecting shaft 4 using self-lubricating copper sheathing 1, safeguarded without refueling,
Coefficient of friction is small, long service life, is more suitable for the working environment of high load, intermittence or oscillating motion, and wear-resisting property is good.Connection
Pressing plate 2 for limit self platform sling 3 is installed on axis 4 and is locked using locking nut, structural stability is improved.Self-locking
The upper end of platform sling 3 is provided with through-hole, slings convenient for lifting loop chain 6, and the lower end of self-locking platform sling 3 is provided with scarce close to the side of coupler body 5.2
Mouthful, provide bigger hook space.Coupler body 5.2 is the U-shaped being laterally arranged, and is connect with mounting plate 5.1 reliably, the opening of U-shaped
Towards self-locking platform sling 3, when locking, the end vertical of coupler body 5.2 is in self-locking platform sling 3, and lifting loop chain 6 unclamps, and self-locking platform sling 3 is detached from
Coupler body 5.2, skids off convenient for workpiece.
The pulling force of the utility model lifting and the power of locking act on self-locking platform sling simultaneously, make to add always when lifting
Lock, structure is simple, and manufacturing cost is low, and stability is high, highly-safe.
