Embodiment：
As shown in Figures 1 to 6, a kind of transmission lockable mechanism on rolling device, wherein rolling device is by anchor cylinder 3, anchor
Ring 4, side panel 2 are made, and its structure is identical with traditional rolling device, does not make too big change.And being driven lockable mechanism 1 includes peace
Driving link mounted in the outside of side panel 2 and the driven member installed in the inner side of side panel 2, driving link include ratchet 6 and with ratchet 6
The ratchet 8 of engagement, ratchet 6 are provided with connecting shaft 11, and the one end of connecting shaft 11 and the center of ratchet 6 are fixed, and driven member includes pedestal
17th, movable holddown 16 and cam 10, the top surface of pedestal 17 are recessed cavity, i.e. pedestal 17 is L-shaped, by the outer wall of pedestal 17 with
The inwall of side panel 2 is fixed, and movable holddown 16 is set in the cavities, and cavity floor indent is deep-slotted chip breaker, the bottom of movable holddown 16
Also indent is deep-slotted chip breaker in face, the passage that two deep-slotted chip breaker compositions pass through for cable 7, the deep-slotted chip breaker of movable holddown 16 is named as
Deep-slotted chip breaker 15, the deep-slotted chip breaker of pedestal 17 are named as lower arcuate slot 19, and cable 7 is usually steel wire rope, and movable holddown 16 is away from ratchet 6
Concave side wall form mounting hole 14, the opposite side of movable holddown 16 is provided with bar hole 13, and bar hole 13 connects with mounting hole 14
It is logical, and cam 10 is arranged in mounting hole 14, can be bonded when cam 10 rotates with the wall of mounting hole 14, the side wall of pedestal 17
Be provided with through hole 18, and connecting shaft 11 sequentially pass through through hole 18, bar hole 13 and mounting hole 14 after be connected with cam 10, activity pressure
Block 16, which is provided with the side wall of mounting hole 14, is provided with cover plate, and cover plate is fixed by bolt and movable holddown 16, and cover plate is complete
Mounting hole 14 is covered, for sheltering from dust etc., in order to avoid influence to use.
One end of ratchet 8 is connected with rolling device and can rotated around junction, and the other end of ratchet 8 is connected with spring
5, and spring 5 is fixed with rolling device, ratchet 8 and spring 5 are arranged on the outside of rolling device, and the one end of ratchet 6 away from rolling device is consolidated
Surely there is adapter sleeve 9, rocking handle 12 is inserted into adapter sleeve 9.
Because coefficient of friction is approximately 0.1 when steel wire rope has during lubrication and general steel contacts, it is therefore necessary to reach 1.5kN
Tension force needs to ensure that manpower, which is directly pressed, to be reached, institute to pressure of the steel wire rope application more than 1 ton without sliding
The function that effectively amplify with the structure, it secondly can also realize the function of self-locking after compressing.
The transmission lockable mechanism of the utility model design, which is arranged on rolling device, utilizes stroke caused by cam structure rotation
Change drives movable holddown 16 to act, and reaches the effect for compressing steel wire rope.
According to use demand, active part will also have counteresteer in addition to power transmission is made into cam rotation to cam
Device, cam is not released under the reaction force effect of steel wire rope after compaction, and from it is mechanical simple, reliable it is upper for
Single direction ratchet is exactly to realize the optimal selection of this demand.The requirement controlled according to size and the requirement fully compressed, are selected
The ratchet of 18 teeth, with reference to trip map, it is about 2.22mm that per tooth stroke, which changes distance,.
Movable holddown 16 is promoted to reach the purpose of compression steel wire rope with cam, therefore movable holddown 16 uses cuboid,
One facial-contracted wire rope of long thickness.
According to steel wire rope footpath fromChange conditions determine steel wire rope cambered surface well width.Consider arch groove
Simplified simulation is employed during width, it has been assumed that in compaction process, steel wire rope sectional area does not change, in practice due to hemp core
Presence and strand wire and silk between crimp, possible real area can reduce.According in ropeway hauling rope
Experience in clamping, steel wire rope compression degree reach 3mm and can be achieved with effectively stepping up.So 17mm cambered surface well width can expire
Foot used demand.Cambered surface groove depth has been set to 4mm simultaneously, the factor such as chamfering when considering to process, final products groove depth 3mm, this
One depth can effectively prevent steel wire rope from deviating from from side in the case of compression.Section processing ovalisation is because oval cross section
It is more that steel wire rope footpath scope is applicable than circular cross-section, and pressure distribution is applied evenly to steel wire rope.
In practical situations both, steel wire rope arch groove not is equally distributed to the power that steel wire rope applies, but in
Between maximum be progressively smaller until that no longer contacting steel wire rope initiation pressure in both sides is changed into 0 to both sides.
Arch groove groove width, which is set to 17mm, can meet that maximum is no more thanSection of the steel wire rope in the case of compression
Deformation, and cambered surface slot cross-section both sides will not oppress steel wire rope, and both sides will not be caused to be formed and become cutting damage steel wire rope by grooving
Situation, and work in-process should all carry out rounding processing to arch groove corner, further avoid the occurrence of such case, and can be
Measuring phase and steel wire rope will not damage steel wire in sharp corner in being put into, take out arch groove and in sliding caused by fortuitous event
Rope.
In order to reduce steel wire rope bending as far as possible, pedestal work in-process requires base seat groove bottom and rolling device reel bottom footpath tangent line
Overlap.
Its user's rule is：Ratchet ratchet is adjusted, movable holddown is located at peak；Wind rope is wound in along guide groove
On rolling device anchor cylinder；Tail rope is placed in the arch groove between movable holddown and pedestal；According to construction requirement, wind rope is progressively discharged,
Until being discharged into required position；Tong Guo Oscillating handle rotating ratchets, untill locking；When easing out wind rope, first Ya Jin Oscillating handles, spine is pushed open
Pawl, releases ratchet lockup state, and Fan makes movable holddown be in relaxation state, adjust tail rope as needed to Zhuan Dong Oscillating handles.
5 people can be up to during compression, and dragging has no that steel wire rope has slip with all strength, shows the rolling of this cam pressing mechanism
Device reaches design anchoring and required；Convenient to use, actual operating time can be achieved to compress for most 20 seconds；It is simple to operate, it is single
People is operable；A small lateral pin has been added on ratchet, has realized anchoring locking and release.
Above-described embodiment, the purpose of this utility model, technical scheme and beneficial effect are entered
One step describes in detail, should be understood that and the foregoing is only specific embodiment of the present utility model, is not used to limit
Determine the scope of protection of the utility model, it is all within the spirit and principles of the utility model, any modification for being made, equally replace
Change, improve, should be included within the scope of protection of the utility model.
