Description
Technical field
The utility model belongs to the technical field of weight-lifting equipment, is specifically related to a kind of crane room top rope outlet rain-proof device.
Background technology
Seat type goliath is provided with machine room, shown in Fig. 1, the power part such as reel 81 grade of hoisting crane is arranged in machine room, and the steel rope 8 of hoisting crane passes machine room top board 1 obliquely from reel 81, walk around the pulley 82 on jib afterwards, need to arrange rope outlet 11 at machine room top board 1 for this reason.Because the pulley on jib constantly longitudinally rotates along jib, make steel rope constantly before and after reciprocal oscillation in the pitch mode, therefore steel rope and machine room top board lengthwise position in the plane constantly change; On the other hand, along with steel rope is in the change of the factors such as mandrel surface windings, steel rope starting point constantly changes in the axially position of reel, makes steel rope constantly left and right back and forth lateral variation, steel rope machine room top board horizontal position in the plane also constantly change.Above-mentioned factor, the size determining the rope outlet of machine room top board is generally about tens centimeters, and so large rope outlet obviously needs to arrange rain insensitive device, enters machine room inside to prevent rainwater.
Existing crane room top rope outlet rain-proof device as shown in Figure 2, comprise and be arranged on traffic cycle on the machine room top board 1 of hoisting crane 91 and mini-roundabout 92, traffic cycle 91 and mini-roundabout 92 are provided with rotating shaft respectively, axes of rotation skew and to pass direction almost parallel with steel rope 8, the rotating shaft 93 of traffic cycle is arranged on machine room top board 11, and mini-roundabout 92 is positioned at above traffic cycle 91, and the rotating shaft of mini-roundabout 92 is arranged on traffic cycle 91 eccentric position, be embedded with rope sling 4 in mini-roundabout 92, traffic cycle 91 offers elongated hole.In working process, when the change in location in length and breadth of steel rope 8, the change in location in length and breadth of rope sling 4 can be actuated, and then drive traffic cycle 91, mini-roundabout 92 passive rotation, thus keep the position of rope sling 4 to be positioned at pulley 82 and reel rising around putting between the two on straight line line.Turn to what angle regardless of traffic cycle 91, mini-roundabout 92, mini-roundabout 92 all covers the elongated hole of traffic cycle, and traffic cycle 91 all covers the rope outlet 11 of machine room top board, thus realizes rainproof.
In above-mentioned existing structure, traffic cycle 91 is covering component, is again supporting member (encorbelment and carry mini-roundabout) and transmission component, primary structure member.Traffic cycle 91, as covering component, requires that size is enough large, to cover the rope outlet 11 of machine room top board completely, so the diameter of traffic cycle needs more than about 1 meter usually; On the other hand, traffic cycle is as supporting member and transmission component, primary structure member, and self only rely on single-point (centre point) to support, encorbelment in all the other positions, so require that traffic cycle self has enough rigidity, intensity, make traffic cycle need to adopt metal sheet to make, thickness also requires to reach certain numerical value.In a word, metal traffic cycle requires large and firm, so its weight reaches hundreds of kilogram usually, seems very heavy, and then brings following problem:
One, the power of traffic cycle passive rotation is from the contact thrust of steel rope to rope sling, thrust direction is along the radial direction of steel rope, this thrust produces onesize antagonistic force to steel rope, and traffic cycle quality is large, heavy, inertia is large, need larger thrust could promote it to rotate, so rope sling can produce larger antagonistic force to steel rope, make the friction force between rope sling and steel rope larger, when adding work frequent, the rapidity of steel rope through rope sling, therefore steel rope abrasion can be made serious, cause expensive steel rope needs frequently to be changed;
Two, the axes of rotation skew of traffic cycle, mean that the rotating shaft axle sleeve 94 of traffic cycle needs the weight that the mode of encorbelmenting supports whole traffic cycle, so its axle sleeve 94 needs to bear huge moment, serious wear between axle sleeve 94 and rotating shaft 93, particularly in Fig. 2, the pressure of A point, B point is very large, and rotary resistance is large, and this increases thrust traffic cycle further and rotates required moment, also the radial reaction force suffered by steel rope is increased, aggravation steel rope abrasion;
Three, also have mini-roundabout above traffic cycle, so this swing system is the eccentric system tilted, this from the third aspect result in traffic cycle rotate needed for comparatively high thrust, also increase the radial reaction force suffered by steel rope, aggravation steel rope abrasion.
Utility model content
The purpose of this utility model is overcome above-mentioned shortcoming and provide a kind of crane room top rope outlet rain-proof device, and it is little to steel rope abrasion degree.
Its object can realize by following scheme: this crane room top rope outlet rain-proof device includes the rope sling that nylon makes, rope sling central authorities offer eyelet hole, it is characterized in that, also being provided with two, left and right can the rocker of swing, the balance staff line of centers of two rockers in left and right is laterally, between the rocker of two, left and right, erection has line slideway, and the bearing of trend of line slideway is laterally; Line slideway is provided with synchronous movement dolly, the wheel of synchronous movement dolly can rollably be arranged on line slideway left and right; Described rope sling is fixedly connected with synchronous movement dolly, and synchronous movement dolly is also fixedly connected with the canopy that can hide rope outlet, and described rope sling, canopy and synchronous movement dolly three connect together and be synchronized with the movement.
Be preferably, described rope sling is embedded in synchronous movement trolley central authorities.
Be more preferably, described synchronous movement dolly is connected to the central part of non-metal canopy.
Described line slideway is divided into two groups, front and back; Every side of described synchronous movement dolly is separately installed with two wheels, and wherein two wheels of side can rollably be arranged on above on one group of line slideway in left and right, and two wheels of opposite side can rollably be arranged on one group of line slideway next left and right.
