Description
Technical field
The utility model relates to bank bridge transportation technology field, particularly relates to a kind of load adjustment mechanism of track bridge lifting steel rope.
Background technology
Gantry container crane is the main handling facilities of container wharf, in today of Container Transport industry high speed development, how to improve its operating efficiency, is the major issue that each harbour, harbour need to be studied.Conventionally, under the condition arrange in place, contour size of the unit(s) being certain, the factors such as the construction parameter feature of the operating efficiency of container handling crane and driver's skilled operation degree, crane, dolly, a braking characteristics are relevant.Because each freight container lifting by crane is not quite similar, to a lot of degree of the quality of casing working, need depend on driver's experience.In addition, also there is the impact of unpredictable operation inertia and wind load, cause suspender and freight container to produce and oscillate in vertical plane, in horizontal surface, produce and reverse and concussion.
Thisly wave and reverse, shake, not only directly affect freight container in handling process and, to the traveling comfort of bit time and operation, safety, also often make freight container produce collision.As collide frequently, will produce impact greatly to the stability of the electric and hydraulic efficiency pressure system of container crane sling, reliability.According to statistics, the fault of container handling crane 80% is at suspender, and the fault of suspender 80% is by casing working is caused.Visible, waving and reverse, shaking of suspender, is the major cause that affects container handling crane work efficiency, and has become the bottleneck that container handling crane was raised the efficiency, reduced fault rate, reduces labour intensity aspect.
Therefore,, in order to guarantee that container handling crane works efficiently, must effectively control waving and reverse, shaking of its suspender.The anti-technology of shaking of current eight ropes is by everybody approval, on container handling crane, extensively adopt, adopt eight hoist ropes to lift suspender, on suspender, fix eight rope points, the function that realization hoists and prevents shaking, but during the method that employing eight is restricted fixing, suspender planeness and the stressed adjustment of steel rope do not have numerical value directly perceived as the impartial foundation of load, rely on maintenance man with hand moving steel rope, artificially to feel the stressing conditions of rope completely, there is coarse problem of adjusting, cause indivedual steel rope unbalance stress, affect the service life of steel rope, easy momentary overload, dangerous.
Utility model content
The purpose of this utility model is for the technological deficiency existing in prior art, and a kind of load adjustment mechanism of track bridge lifting steel rope is provided.
For realizing the technical scheme that the purpose of this utility model adopts, be:
A kind of load adjustment mechanism of track bridge lifting steel rope, comprise digital display tensiometer, upper connecting rod and lower link, described digital display tensiometer comprises measurement main body, be arranged on the read-out of measuring body surfaces, and the engaging lug that is separately positioned on the measurement upper and lower two ends of main body, described upper connecting rod lower end is hinged by the engaging lug of bearing pin and described measurement main body upper end, described upper body of rod upper end is wholely set the first U-shaped shaft clevis in order to be connected with steel rope lower end, described lower body of rod upper end is hinged by the engaging lug of bearing pin and described measurement main body lower end, described lower body of rod lower end is wholely set the connecting portion in order to be connected with over sling.
Described read-out is that the steel rope lower end described in liquid crystal is provided with connecting panel, and described connecting panel can insert the first described U-shaped shaft clevis center the two is hinged by bearing pin accordingly.
The lower end of described upper connecting rod and the upper end of lower link have been wholely set respectively the second U-shaped shaft clevis, on the fork plate of the second described U-shaped shaft clevis, be provided with through hole, described engaging lug can insert the second described U-shaped shaft clevis center the two is hinged by bearing pin matchingly.
Compared with prior art, the beneficial effects of the utility model are:
In the utility model, between each parts, all adopt bearing pin radial type to connect, connect facility and degree of freedom large, can adapt to different connection occasions, simultaneously, on track bridge suspender, eight all calibrate by this load adjustment mechanism with steel rope end, can effectively improve the harmony of lineoutofservice signal pull, at the complete Ke Jiangge load adjustment of calibration, mechanism pulls down and steel rope end is directly connected by bearing pin with the steel rope point of over sling, whole adjustment process is intuitively accurate, avoided human element on adjusting the impact of result, make suspender be operated in eight with under the condition of lineoutofservice signal pull equalization, extended the service life of steel rope, improved safety in utilization.
Accompanying drawing explanation
Figure 1 shows that load adjustment structural scheme of mechanism of the present utility model.
The specific embodiment
Below in conjunction with specific embodiment, the utility model is described in further detail.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
