Description

Technical Field

[0001] The present invention belongs to the technical field of elevators, and particularly relates to an elevator for a transmission tower. Background Art

[0002] During the erection process of a transmission tower, it is necessary to transport personnel and materials up and down. In the erection of a transmission tower, especially at a construction site with convenient transportation or when a large number of components need to be quickly hoisted, a crane can play an important role. However, a crane does not meet the requirements for hoisting personnel. During the tower erection process, personnel can only climb up and down on the transmission tower.

[0003] A pulley block is used to change the direction of force and save effort during the hoisting process of a transmission tower erection. The pulley block has parallel ascending and descending pull ropes hanging downward, but a special person or special equipment is required to draw the tail rope of the descending pull rope. Moreover, the distance between the ascending pull rope and the descending pull rope is only the width of the pulley, and the distance between the ascending pull rope and the descending pull rope is very close. During the lifting process, the cage is prone to entanglement with the ascending pull rope and the descending pull rope, resulting in lifting failure and safety risks.

[0004] During the up and down hoisting process of an elevator, there is a drive failure, resulting in the cage falling and endangering the safety of personnel. Summary of the Invention

[0005] In view of the above analysis, the present invention aims to provide an elevator for a transmission tower to solve the problem that in the prior art, there is a drive failure during the up and down hoisting process of the elevator, resulting in the cage falling and endangering the safety of personnel.

[0006] The object of the present invention is mainly achieved through the following technical solutions:

The cross arm and the base are both arranged on the tower body, and the base is connected to the ground. The elevator includes a drive, a pulling component, a mooring component, a first hook component, a second hook component, a cage, and an anti-falling component. The drive is arranged on the base, the cage is arranged on the pulling component, and the drive is used to drive the pulling component to lift and lower the cage. The cage is used to transport personnel;

[0008] The first hook component and the second hook component are respectively arranged on two legs of the base, the mooring component is arranged on the cross arm, the pulling component is sequentially connected to the mooring component, the first hook component, and the second hook component, and the pulling component forms a triangular rope sleeve;

[0009] The pulling component includes a pull rope;

[0010] The anti - falling component includes a box body, a first clamping block, a second clamping block and a wedge body. The box body is connected to the driver. The first clamping block and the second clamping block are both arranged on the inner wall of the box body. The pulling rope is arranged between the first clamping block and the second clamping block. The wedge body is used to be inserted between the pulling rope and the second clamping block and connect the pulling rope and the first clamping block to prevent the pulling rope from moving and prevent the cage from falling.

[0011] Further, the anti - falling component further includes a guide wheel, a transmission swing block and a swing rod. The guide wheel is rotatably connected to the box body. The transmission swing block is arranged on the side wall of the guide wheel. The pulling rope is wound around the guide wheel and can drive the guide wheel and the transmission swing block to rotate. The swing rod passes through the through - hole of the transmission swing block. Balance blocks and pendulums are respectively arranged at both ends of the swing rod, and the mass of the pendulum is greater than the mass of the balance block. A swing rod spring is also arranged on the swing rod. One end of the swing rod spring is connected to the balance block, and the other end of the swing rod spring is connected to the transmission swing block. The swing rod spring is used to keep the distances between the balance block, the pendulum and the transmission swing block unchanged when the guide wheel rotates.

[0012] Further, the anti - falling component further includes a positioning lock, a support plate and a support rod. The positioning lock is rotatably connected to the inner wall of the box body. The positioning lock includes a first locking rod and a second locking rod. The support plate is connected to the inner wall of the box body. One end of the support rod is connected to the wedge body, and the other end of the support rod passes through the support plate. A wedge body spring is arranged on the support rod. One end of the wedge body spring is connected to the support rod, and the other end of the wedge body spring is connected to the support plate. The wedge body spring is used to push the support rod and the wedge body away from the support plate. A locking rod groove is also arranged on the support rod.

[0013] Further, the mooring component includes a roller and a roller hook. The roller and the roller hook are rotatably connected. The roller hook is used to be connected to the cross - arm, and the roller is used to be connected to the pulling rope. The pulling rope can rotate around the roller.

[0014] Further, the first hook component includes a hook wheel, a transfer buckle, a transfer block and a clamping arm mechanism. The hook wheel is rotatably connected to the transfer buckle. The transfer buckle and the transfer block are rotatably connected. The clamping arm mechanism is arranged on the transfer block, and the clamping arm mechanism is used to be connected to the angle steel column of the base.

[0015] Further, the clamping arm mechanism includes a first clamping arm and a second clamping arm. The first clamping arm and the second clamping arm are respectively used to connect two steel plates of the angle steel column.

[0016] Further, both the first clamping arm and the second clamping arm include a clamping plate, a claw and a clamping post. One end of the clamping plate is connected to the adapter block, and the other end of the clamping plate is connected to the claw. The clamping plates of the first clamping arm and the second clamping arm form a V-shaped clamping arm for connecting to the outer side of the angle steel column. The clamping post can pass through the claw and pull the claw in the direction of the clamping plate. The claw and the clamping plate jointly clamp the angle steel column, thereby connecting the clamping arm mechanism to the angle steel column. The first hook assembly and the second hook assembly can be connected to the base.

[0017] Further, one end of the clamping post can be threadedly connected to the adapter block, and the other end of the clamping post is a nut. By rotating the clamping post, the claw can be pulled in the direction of the clamping plate.

[0018] Further, the first clamping arm further includes a bridging rod and a handle. A rotating shaft is provided on the clamping plate. One end of the handle is rotatably connected to the clamping plate through the rotating shaft, and the other end of the handle is a free end. One end of the bridging rod is rotatably connected to the handle, and the other end of the bridging rod is connected to one end of the clamping post. The other end of the clamping post is a convex block; the convex block is used to prevent the claw from detaching from the clamping post. By pulling the free end of the handle, the handle rotates around the rotating shaft and drives the bridging rod and the clamping post to move in the direction of the adapter block, which can pull the claw in the direction of the clamping plate and clamp the angle steel column.

[0019] Further, the bridging rod includes a notch, and the notch is provided on the outer wall of the bridging rod; the notch can be connected to the rotating shaft to prevent the clamping post from moving away from the adapter block, resulting in the claw detaching from the angle steel column and causing the first hook assembly and the second hook assembly to detach from the base.

[0020] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0021] (1) When the cage falls, the moving speed of the pulling rope of the elevator of the present invention exceeds 11 m / min. The pulling rope pulls the guide wheel, causing the guide wheel and the transmission pendulum block to rotate rapidly. Under the centrifugal action, the pendulum can move away from the transmission pendulum block and strike the first locking rod, causing the second locking rod to disengage from the locking rod groove. The support rod and the wedge move away from the support plate. The wedge can be inserted between the pulling rope and the second clamping block and connect the pulling rope and the first clamping block to prevent the pulling rope from moving, automatically preventing the cage from falling and improving the safety of the elevator;

[0022] (2) The pulling assembly of the elevator of the present invention forms a triangular rope loop, and the driver causes the pulling assembly to rotate around the mooring assembly, the first hook assembly and the second hook assembly to lift the tank cage from the ground to the cross arm; the pulling assembly has no tail rope, and no special person is required to draw the tail rope, which saves manpower; the distance between the ascending section pull rope and the descending section pull rope is greater than the width of the mooring assembly. The hoisted tank cage is always between the ascending section pull rope and the descending section pull rope during the lifting process, and does not contact the ascending section pull rope and the descending section pull rope, and does not get entangled with the ascending section pull rope and the descending section pull rope, thereby ensuring successful lifting and reducing safety risks;

[0023] (3) The fixing block and the pressing plate of the present invention can clamp the draw rope, and the pressing plate bolt can be threadedly connected with the fixing block. By rotating the pressing plate bolt, the pressing plate can be pushed toward the fixing block, thereby clamping the draw rope and preventing the draw rope from being separated from the fixing block; when lifting the cage, the draw rope hook and the cage can be ensured to be below the suspension fastening assembly;

[0024] (4) The transverse bolt seat of the present invention is arranged on the side wall of the fixed block, and the transverse bolt is arranged on the transverse bolt seat. The transverse bolt can pass through the side wall of the fixed block and be inserted into the locking groove, thereby blocking the opening of the locking groove and preventing the connecting rod from being separated from the locking groove; the lever section is rotated, and the lever section can slide along the inclined end surface and drive the transverse locking section to rotate out of the transverse bolt seat, so that the transverse bolt releases the obstruction of the opening of the locking groove, and the connecting rod can be separated from the locking groove. A clamping groove is provided at the vertex of the inclined end surface, and the lever section can be connected to the clamping groove. The clamping groove can limit the rotation of the lever section and prevent the transverse locking section from being inserted into the locking groove. After the lever section is connected to the clamping groove, the user can hold the fixed block with one hand and separate the connecting rod from the locking groove with the other hand, which is convenient for use and operation;

[0025] (5) The clamping plate of the first clamping arm and the clamping plate of the second clamping arm of the lift of the present invention form a V-shaped clamping arm, which is used to connect with the outer side of the angle steel column. The clamping column can pass through the clamping claw and pull the clamping claw toward the clamping plate. The clamping claw and the clamping plate clamp the angle steel column together, thereby connecting the clamping arm mechanism to the angle steel column. The first hook assembly and the second hook assembly can be connected to the base.

[0026] (6) By pulling the free end of the handle of the present invention, the handle rotates around the rotating shaft and drives the connecting rod and the clamping column to move in the direction of the transfer block. Without any tools, the clamping claw can be pulled in the direction of the clamping plate to clamp the angle steel column.

The driver 1, the first hook assembly 4 and the second hook assembly 5 are respectively arranged on two legs of the base 102, the mooring assembly 3 is arranged on the cross arm 101, the pulling assembly 2 is a rope sleeve, and the pulling assembly 2 is sequentially connected to the mooring assembly 3, the driver 1, the first hook assembly 4 and the second hook assembly 5. The pulling assembly 2 forms a triangular rope sleeve, and the cage 6 is arranged on the pulling assembly 2. The pulling assembly 2 is used to lift the cage 6. The cage 6 is used to transport personnel or equipment and materials of the transmission tower.

[0044] Preferably, the mooring assembly 3 is located at the apex angle of the pulling assembly 2, the first hook assembly 4 and the second hook assembly 5 are respectively located at the two base angles of the pulling assembly 2. The triangular rope sleeve between the mooring assembly 3 and the first hook assembly 4 is the ascending section pulling rope, and the triangular rope sleeve between the mooring assembly 3 and the second hook assembly 5 is the descending section pulling rope. The driver 1 is used to make the pulling assembly 2 rotate around the mooring assembly 3, the first hook assembly 4 and the second hook assembly 5, and lift the cage 6 from the ground to the cross arm 101.

[0045] Preferably, as Figure 2 and Figure 5 shown, the pulling assembly 2 includes a pulling rope 21 and a pulling rope hook 22. The pulling rope hook 22 is arranged on the pulling rope 21. The pulling rope 21 is connected end to end to form a rope sleeve. The pulling rope hook 22 is used to connect to the cage 6.

[0046] In some alternative embodiments, the pulling rope hook 22 can also directly hook the goods.

[0047] The parameters of the lift in this embodiment are as follows:

[0048] Lifting weight: below 300 kg;

[0049] Lifting speed: 9 - 11 m / min;

[0050] The draw rope 21 is made of steel wire rope or Dyneema rope, and the diameter of the steel wire rope is greater than or equal to 9.1 mm;

[0051] The power of the driver 1: 1.8 KW;

[0052] The rated lifting force of the driver 1: 3 KN.

[0053] The pulling component 2 of this embodiment has no tail rope, eliminating the need for a dedicated person to complexly draw and coil the tail rope, saving manpower; the distance between the ascending draw rope and the descending draw rope is greater than the width of the mooring component 3. The cage 6 is always between the ascending draw rope and the descending draw rope during the lifting process and does not contact the ascending draw rope and the descending draw rope, making it not easy to entangle with the ascending draw rope and the descending draw rope, ensuring the success of the lifting and reducing safety risks.

[0054] Preferably, as Figure 3 shown, the mooring component 3 includes a roller 31 and a roller hook 32, and the roller 31 and the roller hook 32 are rotatably connected. The roller hook 32 is used to connect to the cross arm 101, and the roller 31 is used to connect to the draw rope 21. The draw rope 21 can rotate around the roller 31 to lift the cage 6. The roller hook 32 can simply and conveniently connect the mooring component 3 to the cross arm 101, facilitating the operation of lifting the cage 6.

[0055] Preferably, as Figure 1 shown, in order to simplify the design and reduce production costs, the structures of the first hook component 4 and the second hook component 5 are the same.

[0056] Preferably, as Figure 4 shown, the first hook component 4 includes a hook wheel 41, a transfer buckle 42, a transfer block 43, and a clamping arm mechanism. The hook wheel 41 is rotatably connected to the transfer buckle 42, the transfer buckle 42 and the transfer block 43 are rotatably connected, and the clamping arm mechanism is arranged on the transfer block 43. The clamping arm mechanism is used to connect to the angle steel column of the base 102. The hook wheel 41 can rotate circumferentially relative to the transfer block 43, keeping the hook wheel 41 and the triangular rope sleeve on one plane, and the hook wheel 41 can maintain the pulling of the draw rope 21.

[0057] Preferably, the clamping arm mechanism includes a first clamping arm and a second clamping arm, and the structures of the first clamping arm and the second clamping arm are the same. The first clamping arm and the second clamping arm are respectively used to connect the two steel plates of the angle steel column.

[0058] Preferably, the first clamping arm includes a clamping plate 44, a claw 45 and a clamping post 46. One end of the clamping plate 44 is connected to the adapter block 43, and the other end of the clamping plate 44 is connected to the claw 45. The clamping plates 44 of the first clamping arm and the second clamping arm form a V-shaped clamping arm for connecting to the outer side of the angle steel column. The clamping post 46 can pass through the claw 45 and pull the claw 45 towards the clamping plate 44. The claw 45 and the clamping plate 44 jointly clamp the angle steel column, thereby connecting the clamping arm mechanism to the angle steel column. The first hook assembly 4 and the second hook assembly 5 can be connected to the base 102.

[0059] In some alternative embodiments, one end of the clamping post 46 can be threadedly connected to the adapter block 43, and the other end of the clamping post 46 is a nut. By rotating the clamping post 46 with a wrench, the claw 45 can be pulled towards the clamping plate 44.

[0060] In some alternative embodiments, the first clamping arm further includes a bridging rod 47 and a handle 48. The clamping plate 44 is provided with a rotating shaft. One end of the handle 48 is rotatably connected to the clamping plate 44 through the rotating shaft, and the other end of the handle 48 is a free end. One end of the bridging rod 47 is rotatably connected to the handle 48, and the other end of the bridging rod 47 is connected to one end of the clamping post 46. The other end of the clamping post 46 is a convex block. The convex block is used to prevent the claw 45 from detaching from the clamping post 46. By pulling the free end of the handle 48, the handle 48 rotates around the rotating shaft and drives the bridging rod 47 and the clamping post 46 to move towards the adapter block 43. Without any tools, the claw 45 can be pulled towards the clamping plate 44 to clamp the angle steel column.

[0061] Preferably, in order to fix the claw 45, the bridging rod 47 includes a notch provided on the outer wall of the bridging rod 47. The notch is used to accommodate the rotating shaft. The notch can be connected to the rotating shaft to prevent the clamping post 46 from moving away from the adapter block 43, resulting in the claw 45 detaching from the angle steel column and causing the first hook assembly 4 and the second hook assembly 5 to detach from the base 102.

[0062] Compared with the prior art, the pulling assembly 2 of the elevator in this embodiment forms a triangular rope loop. The driver 1 causes the pulling assembly 2 to rotate around the mooring assembly 3, the first hook assembly 4, and the second hook assembly 5, and hoists the cage 6 from the ground to the cross arm 101; the pulling assembly 2 has no tail rope, eliminating the need for a dedicated person to reel in the tail rope, thus saving manpower; the distance between the ascending section rope and the descending section rope is greater than the width of the mooring assembly 3. The cage 6 is always between the ascending section rope and the descending section rope during the lifting process and does not contact the ascending section rope and the descending section rope, making it not easy to entangle with the ascending section rope and the descending section rope, ensuring the success of the lifting and reducing safety risks; the clamping plates 44 of the first clamping arm and the clamping plates 44 of the second clamping arm form a V-shaped clamping arm for connecting to the outer side of the angle steel column. The clamping post 46 can pass through the clamping claw 45 and pull the clamping claw 45 towards the direction of the clamping plate 44. The clamping claw 45 and the clamping plate 44 jointly clamp the angle steel column, thereby connecting the clamping arm mechanism to the angle steel column. The first hook assembly 4 and the second hook assembly 5 can be connected to the base 102; by pulling the free end of the handle 48, the handle 48 rotates around the rotating shaft and drives the bridging rod 47 and the clamping post 46 to move towards the adapter block 43. Without any tools, the clamping claw 45 can be pulled towards the direction of the clamping plate 44 to clamp the angle steel column.

[0063] Embodiment 2:

[0064] In order to quickly and safely form a rope loop for the pulling assembly 2, as Figure 1 shown, compared with Embodiment 1, the elevator in this embodiment improves the pulling assembly 2 and adds a suspension fastening assembly 7.

[0065] Preferably, as Figure 2 and Figure 5 shown, the pulling assembly 2 further includes a connecting rod 23 and a screw rod 24. A connecting groove (not shown in the figure) is provided on the connecting rod 23. One end of the rope 21 can be inserted into the connecting groove. The screw rod 24 is threadedly connected to the connecting rod 23. By rotating the screw rod 24, the end of the screw rod 24 can squeeze the rope 21 towards the side wall of the connecting groove, connecting the rope 21 to the connecting groove and preventing the rope 21 from detaching from the connecting rod 23.

[0066] Preferably, a screw hole 25 is provided on the connecting rod 23.

[0067] Preferably, as Figure 5 and Figure 6 shown, the suspension fastening assembly 7 includes a fixing block 71 and a pressing plate 72. The fixing block 71 and the pressing plate 72 can clamp the rope 21. When hoisting the cage 6, it can ensure that the rope hook 22 and the cage 6 are below the suspension fastening assembly 7.

[0068] The hanging fastening assembly 7 further includes a locking groove and a locking projection 73. The locking groove is provided on the fixed block 71, and the locking projection 73 is provided on the locking groove. The connecting rod 23 can be inserted into the locking groove, and the locking projection 73 can be inserted into the screw hole 25, preventing the connecting rod 23 and the pulling rope 21 from detaching from the fixed block 71 along the length direction of the pulling rope 21, and connecting the pulling assembly 2 to form a rope loop.

[0069] Preferably, the open end of the locking groove can be connected to the pulling rope 21, further preventing the connecting rod 23 from detaching from the fixed block 71 along the length direction of the pulling rope 21.

[0070] Preferably, the hanging fastening assembly 7 further includes a first lateral locking mechanism. The first lateral locking mechanism includes a bolt 74 and a bolt seat 75. The bolt seat 75 is provided on the side wall of the fixed block 71, and the bolt 74 is provided on the bolt seat 75. The bolt 74 can pass through the side wall of the fixed block 71 and be inserted into the locking groove, thereby blocking the opening of the locking groove and preventing the connecting rod 23 from detaching from the locking groove.

[0071] Preferably, the first lateral locking mechanism further includes a bolt spring (not shown in the figure). One end of the bolt spring is connected to the bolt 74, and the other end of the bolt spring is connected to the bolt seat 75. The bolt spring is used to push the bolt 74 to keep the bolt 74 in the state of being inserted into the locking groove, preventing the connecting rod 23 from detaching from the locking groove due to accidentally touching the bolt 74 and causing the bolt 74 to disengage from the locking groove, and ensuring the connection between the connecting rod 23 and the locking groove.

[0072] Preferably, the bolt 74 is an L-shaped bolt. The bolt 74 includes a transverse locking section and a lever section. The transverse locking section and the lever section are perpendicularly connected to each other, and both the transverse locking section and the lever section are cylinders. One end of the bolt seat 75 away from the fixed block 71 is an inclined end face. By rotating the lever section, the lever section can slide along the inclined end face and drive the transverse locking section to rotate out of the bolt seat 75, so that the bolt 74 releases the blockage of the opening of the locking groove, and the connecting rod 23 can detach from the locking groove.

[0073] Preferably, a clamping groove is provided at the vertex of the inclined end face. The lever section can be connected to the clamping groove, and the clamping groove can limit the rotation of the lever section to prevent the transverse locking section from being inserted into the locking groove. After the user connects the lever section to the clamping groove, one hand can hold the fixed block 71, and the other hand can disengage the connecting rod 23 from the locking groove, which is convenient for use and operation.

[0074] Preferably, the hanging fastening assembly 7 further includes a second lateral locking mechanism. The second lateral locking mechanism has the same structure as the first lateral locking mechanism. The first lateral locking mechanism and the second lateral locking mechanism are respectively provided at both ends of the fixed block 71, and respectively block the openings at both ends of the locking groove to further prevent the connecting rod 23 and the pulling rope 21 from detaching from the locking groove.

[0075] Preferably, as Figure 6As shown, in order to quickly connect and lock the fixing block 71 and the pressing plate 72, one end of the pressing plate 72 is hinged to the fixing block 71. The hanging fastening assembly 7 also includes a tenon 76, a hanging ring 77 and a locking wrench 78. The tenon 76 is arranged on the other end of the pressing plate 72. The hanging ring 77 and the locking wrench 78 are rotatably connected. The locking wrench 78 is hinged to the fixing block 71. The hanging ring 77 can be connected to the tenon 76. By pulling the locking wrench 78 toward the fixing block 71, the tenon 76 and the pressing plate 72 can be pulled toward the fixing block 71. By further pressing the locking wrench 78, the pressing plate 72 and the fixing block 71 can be clamped to prevent the pull rope 21 from being separated from the pressing plate 72 and the fixing block 71. The operation of clamping and fixing the pull rope 21 is simple and quick.

[0076] Preferably, if Figure 7 As shown, in order to adapt to the pull ropes 21 of different thicknesses, the hanging ring 77 is a hanging ring with adjustable length. The hanging ring 77 includes a U-shaped part 771, a pin 772 and a distance adjusting nut 773. The pin 772 passes through the locking wrench 78. The U-shaped part 771 includes a bent part and two straight rod parts. The two straight rod parts pass through the two ends of the pin 772 respectively. The distance adjusting nut 773 is arranged at the end of the straight rod part and is threadedly connected with the U-shaped part 771. Rotating the distance adjusting nut 773 can change the distance between the bent part and the pin 772, so that the distance between the locking wrench 78 pulling the tenon 76 and the pressure plate 72 can be adjusted, so that the distance between the pressure plate 72 and the fixing block 71 can be changed to adapt to the pull ropes 21 of different thicknesses.

[0077] Preferably, if Figure 6 As shown, in order to prevent the locking wrench 78 from rotating away from the fixing block 71 by itself, the suspension fastening assembly 7 further includes a stop rod 79 , which is disposed on the fixing block 71 .

[0078] Preferably, if Figure 8 As shown, the stop rod 79 includes a first rod segment 791 and a second rod segment 792. The first rod segment 791 is provided with a flange 793. The first rod segment 791 and the flange 793 are both rotatably connected to the fixed block 71. The outer diameter of the flange 793 is larger than the outer diameter of the first rod segment 791. The flange 793 is used to prevent the first rod segment 791 from being separated from the fixed block 71; the second rod segment 792 is arranged perpendicular to the first rod segment 791, and the second rod segment 792 is used to block the locking wrench 78 to prevent the locking wrench 78 from rotating away from the fixed block 71 by itself. 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.

[0079] 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 further 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 card slot (not shown in the figure) and a second card slot (not shown in the figure) are further provided on the outer wall of the fixing block 71. The positioning bead 794 can be connected to the first card 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 card 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, and 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 or perpendicular to the locking wrench 78, facilitating the operation of the locking wrench 78 or maintaining the blocking of the second rod segment 792 on the locking wrench 78.

[0080] 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.

[0081] Embodiment 3:

[0082] As a personnel lifting tool, it is necessary to prevent the cage 6 from falling rapidly due to a failure of the drive 1, such as Figure 1 As shown, this embodiment adds an anti-falling assembly 8 on the basis of Embodiment 1 and Embodiment 2. When the cage 6 falls rapidly, the anti-falling assembly 8 is used to prevent the pulling assembly 2 from moving, preventing the cage 6 from falling to the ground rapidly, thereby improving the safety of the elevator of this embodiment.

[0083] Preferably, if Figure 1 and Figure 9 As shown, the anti-falling component 8 is arranged on the drive 1 , and the pull rope 21 passes through the anti-falling component 8 .

[0084] Preferably, the anti-falling component 8 includes a box body 81, a first clamping block 82, a second clamping block 83, an unlocking mechanism, and a locking mechanism. The box body 81 is connected to the driver 1. The first clamping block 82, the second clamping block 83, the unlocking mechanism, and the locking mechanism are all arranged on the inner wall of the box body 81. The two sides of the pulling rope 21 are respectively the first clamping block 82 and the second clamping block 83.

[0085] Preferably, when the cage 6 falls, the advancing direction of the pulling rope 21 is the direction away from the ground, and this direction is upward. The anti-falling component 8 is arranged vertically along the advancing direction of the pulling rope 21. The unlocking mechanism includes a guide wheel 84, a transmission swing block 85, and a swing rod 86. The guide wheel 84 is rotatably connected to the box body 81. The transmission swing block 85 is arranged on the side wall of the guide wheel 84. The pulling rope 21 is wound around the guide wheel 84 and can drive the guide wheel 84 and the transmission swing block 85 to rotate. A through hole is provided on the transmission swing block 85, and the swing rod 86 passes through the through hole. Balance blocks and pendulums are respectively arranged at both ends of the swing rod 86, and the mass of the pendulum is greater than that of the balance block. A swing rod spring is also provided on the swing rod 86. One end of the swing rod spring is connected to the balance block, and the other end of the swing rod spring is connected to the transmission swing block 85. The swing rod spring is used to keep the distance between the balance block and the pendulum and the transmission swing block 85 unchanged when the guide wheel 84 rotates. At the normal operating speed, the moving speed of the pulling rope 21 does not exceed 11 m / min, the guide wheel 84 rotates slowly, and the distance between the balance block and the pendulum and the transmission swing block 85 can be kept unchanged. When the cage 6 falls, the moving speed of the pulling rope 21 exceeds 11 m / min, the pulling rope 21 pulls the guide wheel 84, causing the guide wheel 84 and the transmission swing block 85 to rotate rapidly. Under the centrifugal force, the pendulum can move away from the transmission swing block 85, unlocking the locking mechanism.

[0086] Preferably, the locking mechanism includes a positioning lock 87, a support plate 88, and a wedging member. The pendulum can strike the positioning lock 87, causing the wedging member to be inserted between the pulling rope 21 and the second clamping block 83 and connecting the pulling rope 21 and the first clamping block 82 to prevent the pulling rope 21 from moving.

[0087] Preferably, the positioning lock 87 is rotatably connected to the inner wall of the box body 81. 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 wedging member includes a wedge body 89 and a support rod 90. The wedge body 89 can be inserted between the pulling rope 21 and the second clamping block 83 and connect the pulling rope 21 and the first clamping block 82 to prevent the pulling 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 body 89 away from the support plate 88, causing the wedge body 89 to be inserted between the pulling rope 21 and the second clamping block 83. A locking rod groove is also provided on the support rod 90. By compressing the wedge spring, the second locking rod can be connected to the locking rod groove to prevent the support rod 90 and the wedge body 89 from moving away from the support plate 88.

[0088] Compared with Embodiments 1-2, when the cage 6 falls, the moving speed of the pulling rope 21 of the elevator in this embodiment exceeds 11 m / min. The pulling rope 21 pulls the guide wheel 84, causing the guide wheel 84 and the transmission pendulum block 85 to rotate rapidly. Under the centrifugal force, the pendulum can move away from the transmission pendulum block 85 and strike the first locking rod, causing the second locking rod to disengage from the locking rod groove. The support rod 90 and the wedge 89 move away from the support plate 88. The wedge 89 can be inserted between the pulling rope 21 and the second clamping block 83 and connect the pulling rope 21 and the first clamping block 82 to prevent the pulling rope 21 from moving, automatically preventing the cage 6 from falling, and improving the safety of the elevator in this embodiment.

[0089] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention.
