As shown in fig. 3, the mounting and fixing mechanism 20 is in a frame shape, the mounting and fixing mechanism 20 includes a side plate i 22 and a side plate ii 21, the side plate ii 21 includes an upper side plate 211 and a lower side plate 212, the upper side plate 211 and the lower side plate 212 are rotatably connected, and the locking mechanism 30 is disposed between the lower side plate 212 and the side plate i 22.
Of course, the mounting and fixing mechanism 20 may have a square frame shape as shown in fig. 3, or may have another shape such as a triangular shape.
One end of the locking mechanism 30 is hinged with the side plate I22, and the other end of the locking mechanism 30 is in clamping fit with the lower side plate 212; the measuring traction rope 10 is inserted in the lower side plate 212 and the locking mechanism 30 in sequence, and the installation fixing mechanism 20 is in a closed state due to the clamping of the lower side plate 212 and the locking mechanism 30 or in an open state due to the disengagement of the lower side plate 212 and the locking mechanism 30.
As shown in fig. 3, the locking mechanism 30 includes an opening plate 31 and a locking plate 32 which are integrally formed, and the opening plate 31 and the locking plate 32 are rotatably connected with the side plate i 22; a clamping head 321 which is convenient to clamp the groove on the lower side plate 212 is arranged at the clamping end of the locking plate 32, and an elastic mechanism (not shown in the figure) which enables the clamping head 321 and the groove to be tightly clamped together is arranged between the locking plate 32 and the side plate I22; open and seted up through-hole I311 on the board 31, through-hole II 2121 has been seted up on the curb plate 212 down, the head end of measuring haulage rope 10 passes through-hole I311 and through-hole II 2121 in proper order and stretches out in the outside of curb plate 212 down, and it installs detachable fixed block 11 to measure haulage rope 10 head end, it is provided with in one side that is close to through-hole I311 to be convenient for measure haulage rope 10 and carries out the tractive and make to open board 31 and drive locking board 32 pivoted auxiliary block 12 to open the haulage rope 10 to measure.
An elastic mechanism which enables the clamping head 321 to be tightly clamped with the groove is also arranged between the upper side plate 211 and the lower side plate 212.
The elastic mechanism is a spring hinge 50 or a torsion spring, and the elastic direction of the elastic mechanism arranged between the upper side plate 211 and the lower side plate 212 makes the lower side plate 212 tend to rotate towards the outside of the closed area. Because an elastic mechanism (the trend that the locking plate 32 rotates towards the side plate II 21 due to the elastic direction of the elastic mechanism) is also arranged between the locking plate 32 and the side plate I22, the two elastic mechanisms act with each other, and when the locking plate 32 and the lower side plate 212 are clamped together, the locking plate 32 and the lower side plate 212 are clamped tightly.
The sliding mechanism comprises a pulley 40, and the pulley 40 is arranged between the side plate I22 and the upper side plate 211. The pulley 40 in fig. 3 is a nylon pulley.
After the pulley is sleeved on the flexible bus 60, as shown in fig. 3, the pulley 40 on the pulley is arranged above the flexible bus 60. Under the action of gravity, the tackle can move from the self-running direction to the lowest point of the sag (namely, the pulley 40 rolls to the lowest point of the wire along the wire) by utilizing the radian of the sag, and the ground personnel can measure the sag by utilizing the measuring traction rope 10 which is hung down. If the sheave 40 of the trolley is not rolling smoothly, a worker standing on the ground may pull the measuring hauling cable 10 diagonally in front of the movement of the trolley. In order to ensure the normal operation of the locking mechanism 30, the length of the rope between the detachable fixed block 11 and the auxiliary block 12 is set to be equal to or slightly longer than the length between the through hole I311 and the through hole II 2121 in the closed state; namely, when a worker standing on the ground obliquely pulls the measuring hauling cable 10, and the auxiliary block 12 is in contact with the through hole I311, the detachable fixed block 11 is in contact with or not in contact with the through hole II 2121, and the force is obliquely applied by the measuring hauling cable, so that the mounting and fixing mechanism 20 is not opened, even if the locking plate 32 slightly rotates downwards under the pushing of the auxiliary block 12, the detachable fixed block 11 is immediately in contact with the through hole II 2121, so that the lower side plate 212 cannot be bounced, and the mounting and fixing mechanism 20 still keeps in a closed state in the downward moving process.
The measuring traction rope 10 is provided with scales so as to be convenient for measuring the distance between the measuring traction rope 10 and the ground.
The tackle is further provided with a deceleration damping device (not shown in the figures), and the measuring hauling cable 10 passes through the deceleration damping device to be connected with the installation fixing mechanism 20 and/or the locking mechanism 30.
The operation of the present invention will be further described with reference to the accompanying drawings.
As shown in fig. 2, when the flexible bus bar 60 is installed, the trolley is installed on the flexible bus bar 60 and is lifted up together with the flexible bus bar 60. After the flexible bus 60 is hung, the tackle moves to the lowest point of the sag of the flexible bus 60 by using the self gravity, and when the movement resistance of the tackle is large, the measuring traction rope 10 can be used for guiding the tackle to move. The measurer can directly read the reading on the measuring traction rope 10 on the ground according to a certain reference object, so that the distance L1 between the tackle and the ground can be obtained, and the sag f of the flexible bus 60 can be accurately obtained according to the vertical height of the wire hanging frame.
After the measurement is finished, the measurement hauling cable 10 is pulled downwards, the auxiliary block 12 on the measurement hauling cable 10 applies force to the opening plate 31 at the moment, the opening plate 31 is stressed to drive the locking plate 32 to rotate downwards, so that the locking plate 32 and the lower side plate 212 are separated from each other, the lower side plate 212 is turned upwards under the action of the elastic mechanism, the installation and fixing mechanism is in an unlocking state, namely an opening state, and the pulley is turned around the soft bus 60 integrally. At the moment, the pulley slowly falls down by loosening the measuring traction rope 10 and measuring the action of the traction rope through the speed reducing damping device; after the pulley is placed on the ground, the detachable fixing block 11 at the head end of the measuring pulling rope 10 is loosened, the measuring pulling rope 10 and the pulley are recovered, and the sag measuring work is completed.
