Detailed Description

The present application is described in further detail below with reference to figures 1-4.

The embodiment of the application discloses perpendicular elbow crane span structure convenient to fixed cable.

Referring to fig. 1, the vertical bridge comprises two bottom plates 1, two side plates 2, three fixing members 3 and three driving mechanisms 4. Two bottom plate 1 mutually perpendicular and fixed connection are in the same place, and two curb plates 2 are located two relative both sides of bottom plate 1 respectively, and 2 picture two bottom plate 1 homogeneous mutually perpendicular of curb plate, and two curb plates 2 and two bottom plate 1 form the cavity of a right angle shape jointly, have all seted up a plurality of louvres 11 on each bottom plate 1, louvre 11 and the inside intercommunication of cavity. Three mounting 3 all is located curb plate 2 and keeps away from one side of bottom plate 1, and one of them mounting 3 corresponds the position of two bottom plate 1 tie points, and remaining two mountings 3 correspond the tip that two bottom plates 1 kept away from each other respectively, and every mounting 3 all can be followed the space between two curb plates 2 and got into in the cavity. Three actuating mechanism 4 all installs between two curb plates 2, and three actuating mechanism 4 and three mounting 3 one-to-one, and actuating mechanism 4 is used for driving the mounting 3 that corresponds and does the removal that is close to or keeps away from 1 direction of bottom plate.

When laying the cable, put into the cavity with the cable from the space opening between two curb plates 2, and make the cable buckle perpendicularly in two bottom plate 1 junctions, then make earlier 3 inside cavities movements of mounting that correspond with two bottom plate 1 junctions, make the position of buckling of this mounting 3 and cable compress tightly at two bottom plate 1 junctions, fix the cable tentatively, then in proper order with other two mountings 3 remove to with the cable butt, lie in two bottom plate 1 tip positions of keeping away from one side each other with the cable and compress tightly simultaneously, with this with cable monolithic stationary to the crane span structure, the fixed effect of cable has been improved, do benefit to the work of laying of cable.

The fixing parts 3 corresponding to the joints of the two bottom plates 1 are fixed shafts, the axes of the fixed shafts are parallel to the two bottom plates 1, and the axial length of each fixed shaft is smaller than the distance between the two side plates 2; the other two fixing pieces 3 are all set as fixing plates, the width of each fixing plate is smaller than the distance between the two side plates 2, and the fixing plates and the corresponding bottom plates 1 are arranged in parallel.

When the cable is fixed, the circumferential surface of the fixed shaft is contacted with the bent part of the cable, and the bent part of the cable is in an arc shape, so that the circumferential surface of the fixed shaft is more fit and adapted with the bent part of the cable, and the fixed effect of the fixed shaft on the bent part of the cable is better; and the cable is located the position that two bottom plates 1 kept away from each other and all is in the state of not buckling, and the area of contact of the plane of fixed plate and cable is bigger, and fixed effect is better.

Elastic pads 31 are fixedly arranged on the circumferential surface of the fixed shaft and the side wall of the fixed plate close to the bottom plate 1, and the elastic pads 31 can be rubber pads or polyurethane pads with lower hardness, so that the elastic pads 31 can replace the fixed shaft and the fixed plate to be in contact with the cable, the pressing force on the cable can be increased through the elastic deformation of the elastic pads 31, the cable can be effectively protected, and the cable is not easy to be damaged due to overlarge pressing force.

The drive mechanism 4 includes a mounting plate 41, a screw 42, and a guide rod 43. The mounting plate 41 is located at one end of the side plate 2 far away from the bottom plate 1, the mounting plate 41 is perpendicular to the moving direction of the corresponding fixing part 3, the screw rod 42 penetrates through the mounting plate 41 and is in threaded connection with the mounting plate, one end of the screw rod 42 is rotatably connected with the fixing part 3, the screw rod 42 is arranged along the moving direction of the fixing part 3, namely the screw rod 42 and the mounting plate 41 are in a mutually perpendicular state, the two guide rods 43 are respectively located at two opposite sides of the screw rod 42, the guide rods 43 are arranged along the axial direction of the screw rod 42, the guide rods 43 penetrate through the mounting plate 41 and are connected with the mounting plate in a sliding mode, and one end of each guide rod 43 is fixedly connected with the fixing part 3.

When the fixing member 3 is driven to move, the screw rod 42 is rotated, the screw rod 42 moves on the mounting plate 41 along the axial direction of the screw rod 42, and the fixing member 3 is limited by the guide rod 43 and cannot rotate along with the screw rod 42, and the fixing member 3 can move synchronously along with the screw rod 42, so that the function of driving the fixing member 3 to move is realized. When the fixing part 3 is abutted to the cable, the cable can generate a reverse acting force on the fixing part 3, but the screw rod 42 cannot move automatically after being stressed due to the self-locking property of the threaded connection of the screw rod 42 and the mounting plate 41, so that the pressing force on the cable is ensured.

Two opposite ends of the mounting plate 41 correspond to the two side plates 2 respectively, and one end of the mounting plate 41 extends downwards and is hinged with one of the side plates 2, so that the mounting plate 41 can rotate on the side plate 2; keep away from and set firmly stopper 21 on curb plate 2 of mounting panel 41 pin joint one side, the one end downwardly extending of self pin joint is kept away from to mounting panel 41 has set firmly connecting block 411, and connecting block 411 butt is on stopper 21, and wears to be equipped with bolt 412 on the connecting block 411, and bolt 412 threaded connection is on stopper 21 behind the through connection piece 411, makes mounting panel 41 can dismantle with this curb plate 2 and link together.

When laying the cable between two curb plates 2, rotate bolt 412 earlier, make bolt 412 disengage from stopper 21, make mounting panel 41 and this curb plate 2 separation, then rotate mounting panel 41 to one side of curb plate 2, spill the opening in two curb plate 2 clearances totally, make mounting panel 41 can not influence the laying work of cable, after the cable is put into between two curb plates 2, again with mounting panel 41 after restoreing on the bolt 412 twists stopper 21 can, easy operation is convenient.

The implementation principle of the vertical elbow bridge convenient for fixing the cable in the embodiment of the application is as follows: through two fixed plates and a fixed axle respectively to the cable compress tightly at the tip that two bottom plates 1 kept away from each other and the position that the cable was buckled, carry out the rigidity to a plurality of positions of cable simultaneously to improve the fixed effect of cable in the crane span structure, overall structure is simple and convenient, the simple operation, the practicality is higher.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
