Abstract
The utility model discloses a kind of self-locking lifting blocks, it is connected to below lifting equipment by wirerope, it include: shell, pulley, pulley spindle, from lockwheel, self-locking wheel shaft and self-locking block, screw thread axis hole there are two being opened up on the shell, the pulley spindle, one end of self-locking wheel shaft is threadedly coupled with described two screw thread axis holes respectively, the other end respectively with pulley, it is connected from lockwheel, the self-locking block welding is on the housing and positioned at described from the lower section of lockwheel, it is described from lockwheel be eccentric cam, the eccentric cam can cooperate to clamp on wirerope with the self-locking block and brake.Through the above way, the utility model is using eccentric cam and the mutually matched structure design of self-locking block, braking can will be clamped by the wirerope on eccentric cam, structure is simple, braking is rapidly, reliably, weight drops when avoiding lifting equipment there was a mechanical failure or brake failure, can be improved the safety of hoisting operation.
Description
Technical field
The utility model relates to lifting block fields, more particularly to a kind of self-locking lifting block.
Background technique
Lifting block (hoisting block) is commonly called as hoist crane.Pass through the simple of sprocket wheel or reel vertical-lifting weight
Hoisting machinery.It is compact structure and easy to use from heavy and light, the easy lifting work suitable for construction.It is generally connected to lifting
Below equipment, cooperation lifting equipment is used together.
But existing lifting block does not have self-locking function, hoisting operation is in the process it is possible that because of lifting equipment machinery
Failure, brake failure and cause weight to will appear safety accident when serious from high falling.
Utility model content
The utility model has emergency braking function mainly solving the technical problems that providing a kind of self-locking lifting block,
It can be improved the security performance of hoisting operation.
In order to solve the above technical problems, the technical solution that the utility model uses is: it is sliding to provide a kind of self-locking lifting
Vehicle is connected to below lifting equipment by wirerope, comprising: shell, pulley, pulley spindle, from lockwheel, self-locking wheel shaft and self-locking
Block opens up on the shell there are two screw thread axis hole, the pulley spindle, self-locking wheel shaft one end respectively with described two thread spindles
Hole is threadedly coupled, and the other end connect with pulley, from lockwheel respectively, the self-locking block welding on the housing and be located at it is described certainly
The lower section of lockwheel, described from lockwheel is eccentric cam, and the eccentric cam can cooperate with the self-locking block by wirerope
Clamp braking.
In one preferred embodiment of the utility model, the eccentric cam when the eccentric cam rotates clockwise
Edge of the edge far from the self-locking block, when the eccentric cam rotates counterclockwise, the edge of the eccentric cam is close to described
Wirerope is clamped when with the full contact of the edge of the self-locking block and is braked by the edge of self-locking block.
The beneficial effects of the utility model are: the utility model is set using eccentric cam and the mutually matched structure of self-locking block
Meter can will clamp braking by the wirerope on eccentric cam, and structure is simple, and braking is rapid, reliable, and lifting equipment is avoided to go out
Weight drops when existing mechanical breakdown or brake failure, can be improved the safety of hoisting operation.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of self-locking one preferred embodiment of lifting block of the utility model；
The components in the drawings are labeled as follows: 1, shell, 2, pulley, 3, pulley spindle, and 4, from lockwheel, 5, self-locking wheel shaft, 6,
Self-locking block, 7, wirerope.
Specific embodiment
The preferred embodiment of the utility model is described in detail with reference to the accompanying drawing, so that the advantages of the utility model
It can be easier to be readily appreciated by one skilled in the art with feature, to make the protection scope of the utility model apparent clear
Define.
Referring to Fig. 1, the utility model embodiment includes:
A kind of self-locking lifting block is connected to below lifting equipment, comprising: shell 1, pulley 2, pulley by wirerope 7
Axis 3 is opened up from lockwheel 4, self-locking wheel shaft 5 and self-locking block 6, the shell 1 there are two screw thread axis hole, the pulley spindle 3, self-locking
One end of wheel shaft 4 is threadedly coupled with described two screw thread axis holes respectively, and the other end is connect with pulley 2, from lockwheel 4 respectively, described
Self-locking block 6 be welded on the shell 1 and be located at it is described from the lower section of lockwheel 4, it is described from lockwheel 4 be eccentric cam, it is described partially
Cardiac prominence wheel can cooperate to clamp on wirerope 7 with the self-locking block 6 and brake.Specifically, when the eccentric cam is clockwise
Edge of the edge of the eccentric cam far from the self-locking block 6, enables wirerope 7 to pass freely through when rotation；When described inclined
The edge of cardiac prominence wheel eccentric cam when rotating counterclockwise close to the edge of the self-locking block 6 until with the self-locking block 6
Wirerope 7 is clamped when edge completely attaches to and is braked.
When work, the rope of steel wire 7 is backward across being wound on pulley 2 from lockwheel 4 and self-locking block 6, when lifting for wirerope 7
It draws, the traction frictional force drive of wirerope 7 is rotated clockwise from lockwheel 4, is made from the edge of lockwheel 4 far from the edge of self-locking block 6
Wirerope 7 normal through；When crane breaks down, wirerope 7 is moved along by weight traction, and the traction of wirerope 7 rubs
It wipes power drive to rotate counterclockwise from lockwheel 4, from the edge of lockwheel 4 close to the edge of self-locking block 6 until complete with the edge of self-locking block 6
Wirerope 7 is clamped and is braked by Full connected, to prevent weight from dropping.
In the description of the present invention, it should be noted that term " on ", "lower", "left", "right", "inner", "outside" etc.
The orientation or positional relationship of instruction be based on the orientation or positional relationship shown in the drawings or the utility model product use when
The orientation or positional relationship usually put, is merely for convenience of describing the present invention and simplifying the description, rather than instruction or dark
Show that signified device or element must have a particular orientation, be constructed and operated in a specific orientation, therefore should not be understood as pair
The limitation of the utility model.The above descriptions are merely preferred embodiments of the present invention, and it is practical new to be not limited to this
Type, for those skilled in the art, the present invention may have various modifications and changes.All essences in the utility model
Mind and principle within, any modification, equivalent replacement, improvement and so on, should be included in the protection scope of the utility model it
It is interior.
The above description is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all
Equivalent structure or equivalent flow shift made based on the specification and figures of the utility model, is applied directly or indirectly in
Other related technical areas are also included in the patent protection scope of the utility model.
