Description

Technical Field

[0001] The present application relates to the technical field of tower cranes, and in particular to a tower crane climbing structure that is easy to climb. Background Art

[0002] Tower crane, also known as tower crane, is mainly used for vertical and horizontal transportation of materials and installation of building components in house construction. Its tower body is composed of multiple tower crane sections.

[0003] When the existing tower crane is climbing, it raises the tower body through its own tower crane sections and then climbs by itself. When the tower crane driver goes up the tower crane, he climbs up through the gap on the tower crane section and the load-bearing beam. However, when climbing, for safety reasons, the tower crane driver will wear a fall arrester, but the fall arrester is connected to the load-bearing beam of the tower crane section through a hook. Whenever the tower crane driver climbs to a position almost flush with the fall arrester, he needs to remove the hook and mount it upward again. However, when the fall arrester is separated from the load-bearing beam, the tower crane driver needs to operate more carefully, which is less safe.

[0004] Therefore, the present invention proposes a tower crane climbing structure that is easy to climb to solve this problem. Summary of the invention

[0005] The purpose of the present application is to solve the problems in the above-mentioned background technology and to provide a tower crane climbing structure that is easy to climb.

[0006] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions:

[0007] A tower crane climbing structure that is easy to climb, comprising:

[0008] A tower crane section on which a ladder is installed;

[0009] A vertical pole is mounted on the tower crane section, a bearing support plate is slidably mounted on the vertical pole, the vertical pole is used to be connected with the hook of the anti-fall device, and the bearing support plate is used to shield the hook of the anti-fall device, so that when the bearing support plate slides away from the bottom of the tower crane section, the anti-fall device is pushed to move in a direction away from the bottom of the tower crane section;

[0010] A driving member is installed on the tower crane section, the driving member includes a connecting rope and a winding roller, the winding roller is rotatably installed on the tower crane section, one end of the connecting rope is connected to the bearing support plate, and the other end is wound around the winding roller;

[0011] A support member is installed on the tower crane section, and the support member includes a support plate, an extension rod and a pulling part. The extension rod is installed on the bearing tray, and the support plate is slidably installed on the tower crane section. The support plate is used to support the extension rod to limit the tendency of the bearing tray to move toward the bottom of the tower crane section. The pulling part is in conflict with the bearing tray. When the bearing tray is in conflict with the pulling part, the pulling part drives the support plate to move toward the bottom of the bearing tray.

[0012] Furthermore, the driving member comprises a guide wheel rotatably mounted on the tower crane section, the guide wheel is used to carry the connecting rope, the winding roller is mounted with a turntable, and the turntable is mounted with a handle;

[0013] When in use, the handle drives the turntable and the winding roller to rotate, so that the connecting rope can be wound up more labor-savingly, which makes it easy to transport the fall arrester to the top of the tower crane section, and is more convenient to use.

[0014] Further, the pulling part includes a sliding rod slidably mounted on the tower crane section, a resisting rod for resisting the sliding rod is mounted on the bearing support plate, a connecting plate is mounted on the sliding rod, a hinged rod is slidably hinged on the connecting plate, a push plate is slidably mounted on the tower crane section, a slide groove is provided on the push plate, a free end of the hinged rod is movably matched with the slide groove, and the push plate is used to push the support plate close to the extension rod;

[0015] When the carrying pallet rises to the highest point, the sliding rod is pushed by the resistance rod, so that the connecting plate moves upward, and the pushing plate is pulled by the hinge rod to move in the direction close to the supporting plate, so that the pushing plate pushes the supporting plate close to the extension rod, and then the supporting plate supports the extension rod and the carrying pallet, limiting the tendency of the carrying pallet to fall downward, thereby increasing the stability of the device when in use.

[0016] Furthermore, a mounting plate is installed on the tower crane section, a guide rod is installed on the support plate, and a connecting spring sleeved on the outside of the guide rod is installed on the support plate, and the connecting spring forces the support plate to move away from the vertical pole;

[0017] When the pushing plate pushes the supporting plate, the supporting plate moves away from the mounting plate, thereby stretching the connecting spring. During the process, the inner wall of the connecting spring is restricted by the side wall of the guide rod, thereby increasing the stability of the connecting spring when in use. While the supporting plate supports the extension rod, the connecting spring is in a stretched state, providing a force in the opposite direction to the supporting plate, thereby reducing the gap between the pushing plate and the supporting rod, thereby increasing the stability of the supporting rod when in use.

[0018] Furthermore, a mounting block is installed at the free end of the guide rod, a bracket plate is installed on the mounting block, a pad is installed on the bracket plate by pulling a spring for sliding, the pad is used to support the bottom of the bearing bracket, and a push rod is installed on the push plate, the push rod is used to push the pad close to the vertical pole;

[0019] When in use, before the pushing plate pushes the mounting block, the bracket plate is first pushed away from the mounting block by the pushing rod. When the pushing plate pushes the mounting block, the bracket plate and the pad plate are moved toward the column together and are located at the bottom of the load-bearing pallet to support it, so that the pad plate and the support plate share the force applied to the load-bearing pallet, thereby further increasing the safety of the device.

[0020] Furthermore, an inclined plate is installed on the pad, a curved plate for contacting with the vertical pole is installed on the free end of the inclined plate, a protruding rod is installed on the curved plate, and a receiving hole for receiving the protruding rod is opened on the vertical pole;

[0021] When the pad is close to the column, it drives the inclined plate close to the column, so that the arc panel fits with the column, so that the inclined plate and the arc panel share the force on the pad to the column, further increasing the stability of supporting the load-bearing pallet; when the arc panel fits with the pole, the protruding rod is inserted into the accommodating hole, thereby increasing the contact area between the arc panel and the pole, thereby increasing the connection strength between the arc panel and the pole, and further increasing the supporting effect of the inclined plate on the pad.

[0022] Furthermore, an extrusion plate is slidably mounted on the tower crane section, a driving rope is mounted on the extrusion plate, and a free end of the driving rope is wound around the guide wheel shaft, so that the extrusion plate contacts the hinge rod when the driving rope is wound.

[0023] When the guide wheel is in use, it can not only carry the connecting rope, but also have the effect of winding it, so that when the connecting rope is wound, the driving rope is also wound through the rotation of the guide wheel, and then the driving rope pulls the extrusion plate close to the hinged rod, so that when the hinged rod pulls the push plate to resist the mounting block, the extrusion plate resists the hinged rod, thereby limiting the tendency of the hinged rod to reset, thereby increasing the stability of the hinged rod and the push plate when in use.

[0024] Furthermore, a limiting main plate and a limiting sub-plate are slidably mounted on the tower crane section, and a groove for accommodating a handle is provided on the limiting main plate and the limiting sub-plate. When the handle is located in the groove, the rotation of the winding roller is limited;

[0025] When the turntable is rotated to wind up the connecting rope, the limiting main plate and the limiting sub-plate are slid so that the grooves thereon accommodate the handle and limit the position of the handle in the vertical direction, thereby limiting the rotation of the winding roller, thereby increasing the stability of the handle during use, reducing the possibility of the connecting rope being accidentally loosened, and increasing the safety of the device.

[0026] Furthermore, an L-shaped groove is provided on the tower crane section, the limiting sub-plate is slidably matched with the L-shaped groove, a plug rod is installed on the limiting sub-plate, and a plug hole for accommodating the plug rod is provided on the limiting main plate;

[0027] When in use, the sliding of the restriction sub-plate in the L-shaped groove is divided into two sections, and the sliding directions are perpendicular to each other. When in use, first slide the restriction main plate and the restriction sub-plate so that the two are close to the vertical pole, and then slide the restriction sub-plate alone, so that the sub-plate drives the insertion rod close to the socket and inserts it into the socket, which increases the stability between the restriction main plate and the restriction sub-plate, further increases the restriction effect of the handle, and increases the stability of the handle when in use.

[0028] Furthermore, a contact block is slidably mounted on the push plate through a contact spring, the push rod is connected to the contact block, a reset plate is slidably mounted on the push plate through a reset spring, the reset plate is used to limit the sliding of the contact block, and a pull rope is mounted on the reset plate;

[0029] When the driver goes up the tower crane, there is no need to reset the device, which is convenient for subsequent descent from the tower crane. When the driver is descending the tower crane, the load-bearing pallet is still at the highest point of the tower crane section. The driver directly connects the fall arrester to the load-bearing pallet. When it reaches the lowest point, the driver slides the limiting main plate and the limiting sub-plate to release the restriction on the winding roller, and then pulls the pull rope to make the support plate and the pad release the support for the load-bearing pallet, and then rotates the winding roller to make the load-bearing pallet fall, and the fall arrester falls with gravity, so that the device can be used normally.

[0030] The beneficial effects of this application are as follows:

[0031] 1. The present application facilitates the climbing of the tower crane operator by installing a ladder on the tower crane section. When the driver is climbing, the fall arrester hook is hung on the vertical pole, and the fall arrester hook is located above the bearing tray. When in use, the connecting rope is reeled in by the rotation of the reel-in roller, and the fall arrester is driven upward by the bearing tray, so that the fall arrester is located at a higher place, and the bearing tray is supported by the supporting member to keep it stable, so that the tower crane operator only needs to disassemble the fall arrester from the tower crane section once to climb a tower crane section, thereby reducing the frequency of separation of the two, thereby increasing the safety of the tower crane operator when climbing.

[0032] 2. When the present application is in use, the handle drives the turntable and the winding roller to rotate, so that the connecting rope can be wound up more labor-savingly, which makes it easy to transport the fall arrester to the top of the tower crane section, and is more convenient in use.

[0033] 3. In the present application, when the load-bearing pallet rises to the highest point, the sliding rod is pushed by the resistance rod to make the connecting plate move upward, and the pushing plate is pulled by the hinged rod to move in the direction close to the supporting plate, so that the pushing plate pushes the supporting plate close to the extension rod, and then the support plate supports the extension rod and the load-bearing pallet, thereby limiting the tendency of the load-bearing pallet to fall downward, thereby increasing the stability of the device when in use.

[0034] 4. In the present application, when the pushing plate pushes the supporting plate, the supporting plate moves away from the mounting plate, thereby stretching the connecting spring. During the process, the inner wall of the connecting spring is restricted by the side wall of the guide rod, thereby increasing the stability of the connecting spring when in use. While the supporting plate supports the extension rod, the connecting spring is in a stretched state, providing a force in the opposite direction to the supporting plate, thereby reducing the gap between the pushing plate and the supporting rod, thereby increasing the stability of the supporting rod when in use.

[0035] 5. When the present application is in use, before the pushing plate pushes the mounting block, the bracket plate is first pushed away from the mounting block by the pushing rod. When the pushing plate pushes the mounting block, the bracket plate and the pad plate are moved toward the column together and are located at the bottom of the load-bearing pallet to support it, so that the pad plate and the support plate share the force applied to the load-bearing pallet, thereby further increasing the safety of the device.

[0036] 6. In the present application, when the pad is close to the column, the inclined plate is driven close to the column, so that the arc panel is fitted with the column, so that the inclined plate and the arc panel share the force on the pad to the column, further increasing the stability of supporting the load-bearing pallet; when the arc panel is fitted with the pole, the protruding rod is inserted into the receiving hole, thereby increasing the contact area between the arc panel and the pole, thereby increasing the connection strength between the arc panel and the pole, and further increasing the supporting effect of the inclined plate on the pad.

[0037] 7. When the guide wheel of the present application is in use, it can not only carry the connecting rope, but also have the effect of winding it up, so that when the connecting rope is wound up, the driving rope is also wound up through the rotation of the guide wheel, and then the driving rope pulls the extrusion plate close to the hinged rod, so that when the hinged rod pulls the push plate to resist the mounting block, the extrusion plate resists the hinged rod, thereby limiting the tendency of the hinged rod to reset, thereby increasing the stability of the hinged rod and the push plate when in use.

[0038] 8. In the present application, when the turntable is rotated to wind up the connecting rope, the limiting main plate and the limiting sub-plate are slid so that the grooves thereon accommodate the handle and limit the position of the handle in the vertical direction, thereby limiting the rotation of the winding roller, thereby increasing the stability of the handle during use, thereby reducing the possibility of the connecting rope being accidentally loosened, and increasing the safety of the device.

[0039] 9. When the present application is in use, the sliding of the limiting sub-plate in the L-shaped groove is divided into two sections, and the sliding directions are perpendicular to each other. When in use, first slide the limiting main plate and the limiting sub-plate so that the two are close to the vertical pole, and then slide the limiting sub-plate separately so that the sub-plate drives the plug rod close to the socket and inserts it into the socket, thereby increasing the stability between the limiting main plate and the limiting sub-plate, further increasing the limiting effect of the handle, and increasing the stability of the handle when in use.

[0040] 10. In the present application, after the driver goes up the tower crane, there is no need to reset the device, so as to facilitate the subsequent descent from the tower crane. When the driver is descending the tower crane, the load-bearing pallet is still at the highest point of the tower crane section. The driver directly connects the fall arrester to the load-bearing pallet. When it reaches the lowest point, the driver slides the limiting main plate and the limiting sub-plate to release the restriction on the winding roller, and then pulls the pull rope to release the support of the support plate and the pad, and then rotates the winding roller to make the load-bearing pallet fall, and the fall arrester falls with gravity, so that the device can be used normally.

DETAILED DESCRIPTION

[0051] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0052] Embodiment 1

[0053] like Figure 1 - Fig. 9 As shown, the present application proposes a tower crane climbing structure that is easy to climb in embodiment 1, comprising:

[0054] The tower crane section 1 is provided with a ladder 101. The tower crane section 1 is a prior art, which is used to form the tower body of the tower crane and to raise the tower body to play a role of climbing. When the tower crane driver is climbing, he climbs through the ladder 101. Compared with directly climbing the load-bearing beam, there are more parts to provide support for the footsteps, and the support position is relatively flat, which improves the safety during climbing;

[0055] The vertical pole 2 is installed on the tower crane section 1, and a bearing support plate 201 is slidably installed on the vertical pole 2. The vertical pole 2 is used to connect with the anti-fall device hook, and the bearing support plate 201 is used to shield the anti-fall device hook, so that when the bearing support plate 201 slides away from the bottom of the tower crane section 1, the anti-fall device is pushed to move in the direction away from the bottom of the tower crane section 1. When in use, the anti-fall device hook is hung on the vertical pole 2, and the hook is located above the bearing support plate 201, so that the anti-fall device hook can be lifted up and lowered. Figure 1From the main perspective, the bearing bracket 201 is slidably installed on the vertical pole 2. When in use, when the bearing bracket 201 slides upward, it drives the entire fall arrester to slide upward and move to the top of the tower crane section 1 of that section, making it more convenient for the tower crane driver to climb. When climbing the same tower crane section 1, there is no need to frequently change the position of the fall arrester hook, which is more convenient and increases the safety of the device when in use;

[0056] The driving member 3 is installed on the tower crane section 1. The driving member 3 includes a connecting rope 301 and a winding roller 302. The winding roller 302 is rotatably installed on the tower crane section 1. One end of the connecting rope 301 is connected to the bearing support plate 201, and the other end is wound around the winding roller 302. Due to the characteristics of the fall arrester, when the safety rope thereon is pulled at a relatively uniform speed, it will not be stuck. Therefore, the winding roller 302 is rotated at a relatively uniform speed, so that the connecting rope 301 pulls the bearing support plate 201 to move upward, so that the fall arrester can smoothly reach the top of the tower crane section 1 of the section, which is convenient for the tower crane driver to climb;

[0057] The support member 4 is installed on the tower crane section 1. The support member 4 includes a support plate 401, an extension rod 408 and a pulling part. The extension rod 408 is installed on the bearing tray 201. The support plate 401 is slidably installed on the tower crane section 1. The support plate 401 is used to support the extension rod 408 to limit the tendency of the bearing tray 201 to move toward the bottom of the tower crane section 1. The pulling part conflicts with the bearing tray 201. When the bearing tray 201 conflicts with the pulling part, the pulling part drives the support plate 401 to move toward the bottom of the bearing tray 201. When in use, when the connecting rope 301 supports the bearing tray 201 to the top of the tower crane section 1, the support plate 401 is driven by the pulling part to move to the bottom of the extension rod 408, and its tendency to fall downward is limited, thereby increasing the stability of the bearing tray 201 when in use, and further increasing the stability of the device when in use;

[0058] Compared with the prior art, a ladder 101 is installed on the tower crane section 1 to facilitate climbing by the tower crane operator. When the driver is climbing, the fall arrester hook is hung on the vertical pole 2, and the fall arrester hook is located above the bearing tray 201. When in use, the connecting rope 301 is wound up by the rotation of the winding roller 302, and the fall arrester is driven upward by the bearing tray 201, so that the fall arrester is located at a higher place, and the bearing tray 201 is supported by the support member 4 to keep it stable, so that when the tower crane operator is climbing, he only needs to disassemble the fall arrester from the tower crane section 1 once to climb a tower crane section 1, which reduces the frequency of separation between the two, thereby increasing the safety of the tower crane operator when climbing.

[0059] Embodiment 2

[0060] like Figure 2 and Fig. 9As shown, the second embodiment further discloses the driving member 3, the supporting member 4 and the tower crane section 1 on the basis of the first embodiment. In the second embodiment, the driving member 3 includes a guide wheel 303 rotatably mounted on the tower crane section 1, the guide wheel 303 is used to carry the connecting rope 301, a turntable 304 is mounted on the winding roller 302, a handle 305 is mounted on the turntable 304, the diameter of the turntable 304 is larger than the winding roller 302, and the handle 305 is eccentrically mounted on the turntable 304, so that the driver can save effort when rotating the turntable 304 through the handle 305. When in use, the turntable 304 and the winding roller 302 are driven to rotate by the handle 305, so that the connecting rope 301 can be wound up more effortlessly, which is convenient for transporting the fall arrester to the top of the tower crane section 1, and is more convenient when in use.

[0061] like Figure 7 As shown, in the second embodiment, the pulling part includes a sliding rod 402 slidably mounted on the tower crane section 1, so as to Figure 1 From the main perspective, the sliding rod 402 is slidably installed on the tower crane section 1 in the vertical direction, and a resisting rod 403 for resisting the sliding rod 402 is installed on the bearing tray 201. When the bearing tray 201 is transported to the top of the tower crane section 1 by the connecting rope 301, the resisting rod 403 resists the sliding rod 402, thereby pushing the sliding rod 402 upward;

[0062] A connecting plate 404 is installed on the sliding rod 402, and a hinged rod 405 is slidably hinged on the connecting plate 404. A through groove is provided on the connecting plate 404, and cylinders are installed on both sides of the ends of the hinged rod 405. The hinged rod 405 is installed in the through groove through the cylinder, and can slide radially along the cylinder in the through groove and rotate along the axial direction of the cylinder. A pushing plate 406 is slidably installed on the tower crane section 1, and a horizontal groove is provided on the tower crane section 1. The pushing plate 406 is slidably connected with the groove so that it can only slide in the horizontal direction along a straight path. A sliding groove 407 is provided on the pushing plate 406, and the free end of the hinged rod 405 is movably matched with the sliding groove 407. Cylinders are also installed on both sides of the free end of the hinged rod 405. The hinged rod 405 is connected with the sliding groove 407 through the cylinder. The cylinder slides in its own radial direction and rotates along its own axial direction in the sliding groove 407, and the pushing plate 406 is used to push the support plate 401 close to the extension rod 408;

[0063] When the carrying pallet 201 rises to the highest point, the sliding rod 402 is pushed by the resistance rod 403, so that the connecting plate 404 moves upward, and the pushing plate 406 is pulled by the hinge rod 405 to move towards the support plate 401, so that the pushing plate 406 pushes the support plate 401 close to the extension rod 408, and then the support plate 401 supports the extension rod 408 and the carrying pallet 201, thereby limiting the tendency of the carrying pallet 201 to fall downward, thereby increasing the stability of the device when in use.

[0064] like Figure 7 As shown, in embodiment 2, a mounting plate 5 is installed on the tower crane section 1, a guide rod 6 is installed on the support plate 401, and a connecting spring 7 sleeved on the outside of the guide rod 6 is installed on the support plate 401. The connecting spring 7 forces the support plate 401 to move away from the vertical pole 2. When the pushing plate 406 pushes the support plate 401, the support plate 401 moves away from the mounting plate 5, thereby stretching the connecting spring 7. During the process, the inner wall of the connecting spring 7 is restricted by the side wall of the guide rod 6, thereby increasing the stability of the connecting spring 7 when in use. When the support plate 401 supports the extension rod 408, the connecting spring 7 is in a stretched state, providing a force in the opposite direction to the support plate 401, thereby reducing the gap between the pushing plate 406 and the support plate 401, thereby increasing the stability of the support plate 401 when in use.

[0065] like Figure 7 and Figure 8 As shown, in the second embodiment, a mounting block 8 is installed at the free end of the guide rod 6. When the push plate 406 contacts the support plate 401, it contacts the mounting block 8 and thus indirectly contacts the support plate 401.

[0066] A bracket plate 9 is installed on the mounting block 8, and a pad plate 10 is slidably installed on the bracket plate 9 by pulling a spring 11. The pad plate 10 is used to support the bottom of the load-bearing pallet 201. A push rod 12 is installed on the push plate 406. The push rod 12 is used to push the pad plate 10 close to the vertical pole 2. When in use, before the push plate 406 pushes the mounting block 8, the bracket plate 9 is first pushed by the push rod 12 to make it away from the mounting block 8. When the push plate 406 pushes the mounting block 8, the bracket plate 9 and the pad plate 10 are together close to the vertical pole 2 and are located at the bottom of the load-bearing pallet 201 to support it, so that the pad plate 10 and the support plate 401 share the force applied to the load-bearing pallet 201, thereby further increasing the safety of the device;

[0067] When the pad 10 supports the load-bearing pallet 201, the pulling spring 11 is always in a stretched state. The pulling spring 11 will generate a force on the pad 10 away from the vertical pole 2, and its reset tendency is limited by the resistance of the pushing rod 12. The resistance of the pulling spring 11 reduces the gap between the pad 10 and the pushing rod 12, thereby increasing the stability of the pad 10 during use.

[0068] like Figure 6As shown, in the second embodiment, an inclined plate 13 is installed on the pad 10, and an arc panel 14 for contacting the upright pole 2 is installed on the free end of the inclined plate 13. The surface of the arc panel 14 facing the upright pole 2 is an arc surface, and the axis of the arc surface is colinear with the axis of the upright pole 2. When the pad 10 approaches the upright pole 2, the inclined plate 13 is driven to approach the upright pole 2, so that the arc panel 14 fits with the upright pole 2, so that the inclined plate 13 and the arc panel 14 share the force on the pad 10 to the upright pole 2, further increasing the stability of supporting the bearing pallet 201;

[0069] A protruding rod 22 is installed on the arc panel 14, and a receiving hole 23 for accommodating the protruding rod 22 is opened on the vertical rod 2. When the arc panel 14 is in contact with the vertical rod 2, the protruding rod 22 is inserted into the receiving hole 23, thereby increasing the contact area between the arc panel 14 and the vertical rod 2, thereby increasing the connection strength between the arc panel 14 and the vertical rod 2, and further increasing the supporting effect of the inclined plate 13 on the pad 10.

[0070] like Figure 3 As shown in the second embodiment, a squeeze plate 15 is slidably mounted on the tower crane section 1, and a driving rope 16 is mounted on the squeeze plate 15. The free end of the driving rope 16 is wound around the rotating shaft of the guide wheel 303. When the driving rope 16 is wound, the squeeze plate 15 contacts the hinge rod 405 to Figure 1 From the main perspective, the extrusion plate 15 slides on the tower crane section 1 in the horizontal direction. When the guide wheel 303 is in use, it can not only carry the connecting rope 301, but also have the effect of winding it up, so that when the connecting rope 301 is wound up, the driving rope 16 is also wound up through the rotation of the guide wheel 303, and then the driving rope 16 pulls the extrusion plate 15 close to the hinged rod 405, so that when the hinged rod 405 pulls the push plate 406 to contact the mounting block 8, the extrusion plate 15 contacts the hinged rod 405, thereby limiting the tendency of the hinged rod 405 to reset, thereby increasing the stability of the hinged rod 405 and the push plate 406 when in use.

[0071] like Figure 4 and Fig. 9 As shown in the second embodiment, a limiting main plate 17 and a limiting sub-plate 18 are slidably mounted on the tower crane section 1. A groove 24 for accommodating the handle 305 is provided on the limiting main plate 17 and the limiting sub-plate 18. When the handle 305 is located in the groove 24, the rotation of the winding roller 302 is restricted to prevent the winding roller 302 from rotating. Figure 1From the main perspective, the limiting main plate 17 and the limiting sub-plate 18 slide in the horizontal direction. When the rotating dial 304 rotates to wind up the connecting rope 301, the limiting main plate 17 and the limiting sub-plate 18 are slid so that the groove 24 thereon accommodates the handle 305 and limits the position of the handle 305 in the vertical direction, thereby limiting the rotation of the winding roller 302, thereby increasing the stability of the handle 305 during use, thereby reducing the possibility of the connecting rope 301 being accidentally loosened, and increasing the safety of the device.

[0072] Embodiment 3

[0073] like Figure 1 - Fig. 9 As shown, the third embodiment further discloses the present application on the basis of the second embodiment. In the third embodiment, an L-shaped groove 19 is provided on the tower crane section 1, and the limiting sub-plate 18 is slidably matched with the L-shaped groove 19. A plug rod 20 is installed on the limiting sub-plate 18, and a socket 21 for accommodating the plug rod 20 is provided on the limiting main plate 17. When in use, the sliding of the limiting sub-plate 18 in the L-shaped groove 19 is divided into two sections, and the sliding directions are perpendicular to each other. When in use, the limiting main plate 17 and the limiting sub-plate 18 are first slid so that the two are close to the vertical pole 2, and then the limiting sub-plate 18 is slid separately, so that the limiting sub-plate 18 drives the plug rod 20 to be close to the socket 21 and inserted into the socket 21, thereby increasing the stability between the limiting main plate 17 and the limiting sub-plate 18, further increasing the limiting effect of the handle 305, and increasing the stability of the handle 305 when in use.

[0074] In the third embodiment, the contact block 25 is slidably mounted on the push plate 406 via the contact spring 26, the push rod 12 is connected to the contact block 25, and the reset plate 28 is slidably mounted on the push plate 406 via the reset spring 27. The reset plate 28 is used to limit the sliding of the contact block 25. A pull rope 29 is installed on the reset plate 28. The elastic coefficient of the contact spring 26 is smaller than the elastic coefficient of the connecting spring 7. Figure 1From the main perspective, the contact block 25 is slidably installed on the push plate 406 in the horizontal direction, and the reset plate 28 is installed on the push plate 406 in the vertical direction. When the push plate 406 contacts the mounting block 8, the reset plate 28 contacts the side of the contact block 25 away from the mounting block 8, restricting its sliding so that it can remain stable. When the reset plate 28 is pulled downward by the pull rope 29 to release the contact block 25, the connection spring 7 pulls the mounting block 8 to reset. Since the elastic coefficient of the contact spring 26 is smaller than that of the connection spring 7, so that the contact block 25 is compressed, so that the interference of the mounting block 8 is released and the interference of the pad 10 is released, so that the two release the support of the bearing support plate 201. In the specific implementation, a rod body can be installed on the reset plate 28. The rod body is not shown in the figure for the convenience of displaying the reset spring 27. A hole is opened on the push plate 406 to be slidably connected with the rod body. The hole restricts the rod body so that the reset plate 28 can only slide in the vertical direction, which increases the limiting effect of the reset plate 28 on the contact block 25;

[0075] When the driver goes up the tower crane, there is no need to reset the device, which is convenient for subsequent descent from the tower crane. When the driver is descending the tower crane, the load-bearing pallet 201 is still at the highest point of the tower crane section 1. The driver directly connects the fall arrester to the load-bearing pallet 201. When it reaches the lowest point, the driver slides the limiting main plate 17 and the limiting sub-plate 18 to release the restriction on the winding roller 302, and then pulls the pull rope 29 to release the support of the support plate 401 and the pad 10 to the load-bearing pallet 201, and then rotates the winding roller 302 to make the load-bearing pallet 201 fall, and the fall arrester falls with gravity, so that the device can be used normally.

[0076] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
