In the transmission tower assembly, especially in construction sites with convenient transportation or when a large number of components need to be hoisted quickly, cranes can play an important role. However, cranes are not suitable for hoisting personnel. During the tower assembly process, personnel can only climb up and down the transmission tower.

[0003] The pulley block is used to change the direction of force and save effort during the hoisting process of the transmission tower assembly. The pulley block suspends the parallel pull ropes of the ascending section and the descending section downwards, but it is necessary to equip a special person or special equipment to pull out the tail rope of the descending section. Moreover, the distance between the pull ropes of the ascending section and the descending section is only the width of the pulley. The distance between the pull ropes of the ascending section and the descending section is very close. The cage is easy to get entangled with the pull ropes of the ascending section and the descending section during the lifting process, causing lifting failure and safety risks.

By moving the second rod segment 792 until it is parallel to the locking wrench 78, the locking wrench 78 can rotate around the hinge axis with the fixed block 71; by moving the second rod segment 792 until it is perpendicular to the locking wrench 78, the locking wrench 78 is blocked by the second rod segment 792 and cannot rotate around the hinge axis with the fixed block 71, preventing the locking wrench 78 from rotating away from the fixed block 71 on its own, thereby changing the distance between the pressure plate 72 and the fixed block 71, causing the pull rope 21 to detach from the pressure plate 72 and the fixed block 71.

[0052] Preferably, in order to enable the second rod segment 792 to be fixed in a position parallel or perpendicular to the locking wrench 78, the stop rod 79 also includes a positioning bead 794 and a positioning spring 795. The positioning bead 794 and the positioning spring 795 are both arranged in the positioning bead groove of the first rod segment 791. One end of the positioning spring 795 is connected to the positioning bead 794, and the other end of the positioning spring 795 is connected to the positioning bead groove. The positioning spring 795 is used to push the positioning bead 794 out of the positioning bead groove. A first slot (not shown in the figure) and a second slot (not shown in the figure) are also provided on the outer wall of the fixing block 71. The positioning bead 794 can be connected to the first slot, and the second rod segment 792 can be parallel to the locking wrench 78; the positioning bead 794 can be connected to the second slot, and the second rod segment 792 can be perpendicular to the locking wrench 78. The positioning spring 795 can always push the positioning bead 794. The positioning bead 794 prevents the first rod segment 791 from rotating, so that the second rod segment 792 can be fixed in a position parallel to or perpendicular to the locking wrench 78, which is convenient for pulling the locking wrench 78 or keeping the second rod segment 792 blocking the locking wrench 78.

[0053] When the locking cam 75 is in the state of being moved, the locking cam 74 can be locked to the locking cam 74 by clamping the locking cam 74 on the locking cam side, so that the locking cam 74 can be locked to the locking cam side, thereby locking the locking cam 74 in the state of being moved. When the locking lever 78 is in the unlocking state, the locking lever 78 is in the unlocking state, and the locking lever 78 is locked.

The first clamp block 82 and the second clamp block 83 are located on both sides of the pull rope 21 respectively.

[0057] Preferably, when the cage 6 falls, the forward direction of the pull rope 21 is the direction away from the ground, which is upward, and the setting direction of the anti-falling assembly 8 is to be set up and down along the forward direction of the pull rope 21. The unlocking mechanism includes a guide wheel 84, a transmission pendulum block 85 and a pendulum rod 86. The guide wheel 84 is rotatably connected to the box body 81, and the transmission pendulum block 85 is arranged on the side wall of the guide wheel 84. The pull rope 21 is wound around the guide wheel 84 and can drive the guide wheel 84 and the transmission pendulum block 85 to rotate; the transmission pendulum block 85 is provided with a through hole, and the pendulum rod 86 passes through the through hole; the two ends of the pendulum rod 86 are respectively provided with a balance block and a pendulum, and the mass of the pendulum is greater than the balance block; the pendulum rod 86 is also provided with a pendulum rod spring, one end of the pendulum rod spring is connected to the balance block, and the other end of the pendulum rod spring is connected to the transmission pendulum block 85, and the pendulum rod spring is used to keep the distance between the balance block and the pendulum and the transmission pendulum block 85 unchanged when the guide wheel 84 rotates. Under normal operating speed, the movement speed of the pull rope 21 does not exceed 11m / min, the guide wheel 84 rotates slowly, and the distance between the balance block and the pendulum and the transmission pendulum block 85 can remain unchanged; when the tank cage 6 falls, the movement speed of the pull rope 21 exceeds 11m / min, the pull rope 21 pulls the guide wheel 84, causing the guide wheel 84 and the transmission pendulum block 85 to rotate rapidly, and the pendulum can be moved away from the transmission pendulum block 85 under the centrifugal effect, so that the locking mechanism is unlocked.

[0058] Preferably, the locking mechanism includes a positioning lock 87, a support plate 88 and a wedge. The pendulum can strike the positioning lock 87 to insert the wedge between the pull rope 21 and the second clamp 83, and connect the pull rope 21 and the first clamp 82 to prevent the pull rope 21 from moving.

[0059] Preferably, the positioning lock 87 is rotatably connected to the inner wall of the box body 81, and the positioning lock 87 includes a first locking rod and a second locking rod. The support plate 88 is connected to the inner wall of the box body 81. The wedge member includes a wedge 89 and a support rod 90. The wedge 89 can be inserted between the pull rope 21 and the second clamping block 83, and connects the pull rope 21 with the first clamping block 82 to prevent the pull rope 21 from moving. A wedge spring is provided on the support rod 90, one end of the wedge spring is connected to the support rod 90, and the other end of the wedge spring is connected to the support plate 88. The wedge spring is used to push the support rod 90 and the wedge 89 in a direction away from the support plate 88, so that the wedge 89 is inserted between the pull rope 21 and the second clamping block 83. The support rod 90 is also provided with a locking rod groove, which compresses the wedge spring. The second locking rod can be connected to the locking rod groove and prevents the support rod 90 and the wedge 89 from moving in a direction away from the support plate 88.

[0060] Compared with Examples 1-2, when the cage 6 falls, the movement speed of the pull rope 21 of the elevator of this embodiment exceeds 11m / min, and the pull rope 21 pulls the guide wheel 84, causing the guide wheel 84 and the transmission pendulum block 85 to rotate rapidly. Under the action of centrifuge, the pendulum can move away from the transmission pendulum block 85 and knock the first locking rod to disengage the second locking rod from the locking rod groove. The support rod 90 and the wedge 89 move away from the support plate 88, and the wedge 89 can be inserted between the pull rope 21 and the second clamp block 83, and connect the pull rope 21 to the first clamp block 82, thereby preventing the pull rope 21 from moving and automatically preventing the cage 6 from falling, thereby improving the safety of the elevator of this embodiment.
