Description

Technical Field

[0001] This utility model relates to the field of construction machinery technology, and in particular to a fall protection device and a self-climbing mechanism. Background Technology

[0002] A self-climbing mechanism is a device that can autonomously climb along vertical or inclined tracks and structures (such as buildings, towers, piers, etc.) without the assistance of external lifting equipment, using its own power system and mechanical structure. This device is widely used in construction, wind turbine tower maintenance, and robotic climbing, and is favored for its efficiency, safety, and flexibility.

[0003] However, when a self-climbing mechanism is operating at height, if there is a power outage, mechanical failure, or operational error, the equipment may fall from a height, causing a serious safety accident. Utility Model Content

[0004] This utility model provides a fall protection device and a self-climbing mechanism to address the shortcomings of existing self-climbing mechanisms that, during high-altitude operations, may cause equipment to fall from heights in the event of a power outage, mechanical failure, or operational error, resulting in serious safety accidents. It prevents equipment from falling in emergency situations such as power outages or mechanical failures, ensuring equipment safety under the most unfavorable conditions and effectively avoiding personal injury and property damage caused by equipment falls. It also improves the reliability and safety of the self-climbing mechanism.

[0005] This utility model provides a fall protection device, comprising:

[0006] A fixing seat is used to install on the inner side of the self-climbing mechanism facing the pier, and the fixing seat has a first mating surface that is inclined from bottom to top towards the pier.

[0007] An insert is slidably connected to the first mating surface. The horizontal cross-section of the insert gradually decreases from bottom to top. The side of the insert away from the fixed seat is movably abutting against the pier column.

[0008] An electromagnet module is provided at the bottom of the fixing base and is correspondingly arranged with the insert. The electromagnet module is used to attract and fix the insert when it is energized and in contact with it.

[0009] An elastic pushing module is connected between the fixed base and the insert. The elastic pushing module is used to push the insert upward along the first mating surface after the electromagnet module is de-energized.

[0010] According to the present invention, a fall prevention device further includes a slide rail mechanism, which is disposed on one of the insert or the fixed base, and the other is provided with a slide groove for cooperating with the slide rail mechanism.

[0011] According to the present invention, a fall prevention device is provided, wherein the upper end of the slide rail mechanism is provided with a limiting end, which is used to limit the relative sliding distance between the insert and the fixed seat.

[0012] According to the present invention, the number of elastic pushing modules is two, and the two elastic pushing modules are symmetrically arranged on both sides of the first mating surface along the height direction.

[0013] According to the present invention, an anti-fall device is provided, wherein the elastic pushing module includes a guide rod, a spring and an adjusting slider. The two ends of the guide rod are fixedly connected to the fixed base through connecting seats. The guide rod extends along the inclined direction of the first mating surface. One end of the adjusting slider is fixedly connected to the insert, and the other end of the adjusting slider is movably sleeved on the guide rod. The spring is sleeved on the guide rod, and the two ends of the spring respectively abut against the adjusting slider and the connecting seat at the lower end of the guide rod.

[0014] According to the present invention, an anti-fall device is provided, wherein the adjusting slider is provided with a pin hole, the fixing seat is provided with a fixing hole corresponding to the pin hole, and a safety pin passes through the pin hole and the fixing hole to fix the relative position of the insert and the fixing seat.

[0015] According to the present invention, a fall prevention device further includes a friction plate, which is connected to the contact surface where the insert and the pier movably abut.

[0016] According to the present invention, a fall protection device further includes an electric push rod connected to the insert. The electric push rod is used to drive the insert to move downward so that the spring is in a compressed state.

[0017] According to the present invention, a fall protection device further includes an electromagnetic induction coil module, which is disposed on the guide rod. The electromagnetic induction coil module is used to drive the adjusting slider to move downward to press the insert, so that the spring is in a compressed state.

[0018] This utility model also provides a self-climbing mechanism, comprising:

[0019] A frame assembly, wherein the frame assembly encloses a climbing space for passing through a pier column;

[0020] The fall arrestor as described above is mounted on the frame assembly and located within the climbing space.

[0021] The anti-fall device and self-climbing mechanism provided by this utility model involve sliding an insert on the first mating surface of a fixed base. The first mating surface faces the pier from bottom to top, and the horizontal cross-section of the insert gradually decreases from bottom to top. Under normal operating conditions, the electromagnet module is energized and adheres to the insert, allowing the self-climbing mechanism to operate normally. However, in the event of a power outage or mechanical failure, the electromagnet module loses power, and the elastic pushing module activates, pushing the insert upwards along the first mating surface. Because the horizontal cross-section of the insert gradually decreases from bottom to top and moves in contact with the pier, a self-locking angle is formed between the insert and the fixed base. When the insert contacts the pier, during the descent, the frictional force generated by the pressing of the insert against the pier exceeds the device's own weight, ultimately securing it firmly against the pier. This effectively prevents the self-climbing mechanism and equipment from falling, ensuring the safety of the equipment under the most unfavorable conditions. It effectively avoids personal injury or death caused by the equipment falling and damaging surrounding facilities. At the same time, it can effectively improve the reliability of the self-climbing mechanism under various working conditions, reduce the risk of equipment damage and safety accidents caused by sudden situations, and thus improve the overall safety of the self-climbing mechanism. When the equipment failure is resolved, the anti-fall mechanism does not need to return to the electromagnet module's engaged state; the anti-fall mechanism will only prevent the equipment from falling, not hinder its ascent.

[0034] The following is combined Figure 1 and Figure 2 The fall protection device and self-climbing mechanism provided in this utility model embodiment will be described in detail through specific embodiments and application scenarios.

[0035] In the embodiments of this utility model, such as Figure 1 As shown, a fall arrestor 10 includes a fixed base 100, an insert 200, an electromagnet module 400, and an elastic pushing module 300. The fixed base 100 is installed on the inner side of the self-climbing mechanism 1 facing the pier. The fixed base 100 has a first mating surface 110 that is inclined from bottom to top towards the pier. The insert 200 is slidably connected to the first mating surface 110. The horizontal cross-section of the insert 200 gradually decreases from bottom to top. The side of the insert 200 away from the fixed base 100 is movably abutting against the pier. The electromagnet module 400 is located at the bottom of the fixed base 100 and is correspondingly arranged with the insert 200. The electromagnet module 400 is used to attract and fix the insert 200 when it is energized and in contact with it. The elastic pushing module 300 is connected between the fixed base 100 and the insert 200. The elastic pushing module 300 is used to push the insert 200 upward along the first mating surface 110 after the electromagnet module 400 is de-energized.

[0036] The fixing base 100 can be installed on the inner side of the self-climbing mechanism 1 facing the pier, providing a stable support foundation for the entire fall arrest device 10, ensuring that the device can move together with the self-climbing mechanism 1, and can accurately apply force to the pier when needed. At the same time, being installed on the inner side facing the pier facilitates the contact between the insert 200 and the pier to achieve the fall arrest function.

[0037] The first mating surface 110 is inclined upwards towards the pier. The first mating surface 110 guides the insert 200 to slide along a predetermined inclined path. Its inclination angle is key to achieving the "the tighter it gets" self-locking effect. When the insert 200 moves upwards along this surface under the action of the elastic pushing module 300, the inclined surface decomposes the upward thrust of the elastic pushing module 300 into a force perpendicular to the pier (generating positive pressure) and a force along the pier direction. As the insert 200 moves upwards, a greater upward thrust is needed to overcome the resistance generated by friction between the insert 200 and the pier. This, in turn, generates a greater positive pressure through the inclined surface, thus forming positive feedback and achieving self-locking.

[0038] The insert 200 is slidably connected to the first mating surface 110. Through the sliding connection, the insert 200 can move freely on the first mating surface 110, thereby switching between contact and separation states with the pier column according to the force changes of the electromagnet module 400 and the elastic pushing module 300.

[0039] The horizontal cross-section of the insert 200 gradually decreases from bottom to top. When the insert 200 is pushed upward, because its upper "width" is smaller than its lower "width," the insert 200 needs to "wedge" or "lock" into contact with the pier. To move it further upward, a greater force needs to be overcome (because the effective contact area / lever arm may increase, and the existing frictional force needs to be overcome). This causes the normal pressure (abutment force) between the insert 200 and the pier to continuously increase during the upward movement.

[0040] The side of the insert 200 away from the fixed seat 100 is movably abutted against the pier. Under normal working conditions, the insert 200 maintains a certain gap with the pier, which does not affect the normal climbing of the self-climbing mechanism 1. In the event of an accidental fall, the insert 200 can quickly abut against the pier and prevent the self-climbing mechanism 1 from falling further through friction, thus achieving the fall prevention function.

[0041] The electromagnet module 400 is located at the bottom of the fixing base 100 and is correspondingly positioned to the insert 200. By installing the electromagnet module 400 at the bottom of the fixing base 100 and corresponding to the insert 200, the electromagnet module 400 can exert a direct force on the insert 200. When the electromagnet module 400 is energized and the insert 200 is in contact with the electromagnet module 400, the electromagnet module 400 generates a magnetic force that attracts the insert 200, keeping it stationary.

[0042] The elastic push module 300 is connected between the fixed base 100 and the insert 200, enabling the elastic push module 300 to transmit force between the fixed base 100 and the insert 200, providing restoring force to the insert 200, and is the key structural connection for realizing the self-locking of the insert 200.

[0043] The elastic pushing module 300 is used to push the insert 200 upward along the first mating surface 110 after the electromagnet module 400 loses power. That is, when the electromagnet module 400 loses power and the magnetic force disappears, the elastic pushing module 300 uses its own elastic potential energy to push the insert 200 upward along the first mating surface 110, so that the insert 200 abuts against the pier. In this way, in the event of an accidental fall or power outage in the self-climbing mechanism 1, the protective state of the fall arrestor 10 can be quickly restored, ensuring that the self-climbing mechanism 1 will not continue to fall and ensuring construction safety.

[0044] In some embodiments, if there are no special requirements for the surface of the pier, the fall arrestor 10 can remain attached to the wall from its initial state and climb upwards.

[0045] This application slides the insert 200 onto the first mating surface 110 of the fixed base 100. The first mating surface 110 faces the pier from bottom to top, and the horizontal cross-section of the insert 200 gradually decreases from bottom to top. Under normal operating conditions, the electromagnet module 400 is energized and adheres to the insert 200, allowing the self-climbing mechanism 1 to perform normal lifting operations. However, in the event of a power outage or mechanical failure, the electromagnet module 400 loses power, and the elastic pushing module 300 activates, pushing the insert 200 upwards along the first mating surface 110. Because the horizontal cross-section of the insert 200 gradually decreases from bottom to top and moves into contact with the pier, a self-locking angle is formed between the insert 200 and the fixed base 100. When the insert 200 contacts the pier, during the descent of the entire machine, the frictional force generated by the self-climbing mechanism 1 through the compression of the insert 200 against the pier exceeds its own weight, ultimately securing it tightly against the pier. It effectively prevents the self-climbing mechanism 1 and the equipment from falling downwards, thus ensuring the safety of the equipment under the most unfavorable conditions. It effectively avoids personal injury or death caused by the equipment falling and hitting people below, as well as property damage caused by damage to surrounding facilities. At the same time, it can also effectively improve the reliability of the self-climbing mechanism 1 under various working conditions, reducing the risk of equipment damage and safety accidents due to sudden situations, thereby improving the overall safety of the self-climbing mechanism 1. When the equipment malfunction is resolved, the fall arrestor 10 does not need to return to the electromagnet module 400 engaged state; the fall arrestor 10 will only prevent the equipment from falling, without hindering its ascent.

[0046] Reference Figure 1 According to the present invention, a fall prevention device 10 also includes a slide rail mechanism 500, which is disposed on one of the insert 200 or the fixed seat 100, and the other is provided with a slide groove 210 for cooperating with the slide rail mechanism 500.

[0047] Understandably, the cooperation between the slide rail mechanism 500 and the slide groove 210 provides a precise guiding path for the relative movement between the insert 200 and the fixed seat 100. During the operation of the fall arrestor 10, the insert 200 needs to move in a specific direction on the fixed seat 100. The slide rail mechanism 500 is set on either the insert 200 or the fixed seat 100, and the other is provided with a matching slide groove 210, so that the insert 200 can only move along the trajectory defined by the slide groove 210, avoiding deviation in the direction of movement and ensuring the accuracy and stability of the movement.

[0048] Reference Figure 1 According to the present invention, a fall prevention device 10 is provided, wherein the upper end of the slide rail mechanism 500 is provided with a limiting end 510, which is used to limit the block from rushing out of the slide rail mechanism 500 during the self-test before climbing.

[0049] Reference Figure 1 According to the present invention, a fall prevention device 10 is provided, wherein there are two elastic pushing modules 300, and the two elastic pushing modules 300 are symmetrically arranged on both sides of the first mating surface 110 along the height direction.

[0050] Understandably, using two elastic pushing modules 300 provides a greater elastic pushing force compared to a single module. After the electromagnet module 400 loses power, the elastic pushing modules 300 need to quickly push the insert 200 upwards along the first mating surface 110, ensuring it is tightly against the pier to prevent fall. The combined action of the two modules ensures sufficient force to push the insert 200, allowing it to contact the pier promptly and effectively even under heavy loads or large impacts, reliably preventing fall and significantly improving the reliability of the fall arrestor 10.

[0051] Two elastic pushing modules 300 are symmetrically arranged on both sides of the first mating surface 110 along the height direction, which can ensure that the force distribution is more uniform when pushing the insert 200.

[0052] Reference Figure 1 According to the present invention, a fall prevention device 10 is provided, wherein the elastic pushing module 300 includes a guide rod 310, a spring 320 and an adjusting slider 330. The two ends of the guide rod 310 are fixedly connected to the fixed base 100 through the connecting seat 340. The guide rod 310 extends along the inclined direction of the first mating surface 110. One end of the adjusting slider 330 is fixedly connected to the insert 200, and the other end of the adjusting slider 330 is movably sleeved on the guide rod 310. The spring 320 is sleeved on the guide rod 310, and the two ends of the spring 320 respectively abut against the connecting seat 340 at the lower end of the guide rod 310.

[0053] Understandably, the guide rod 310 provides stable guidance and support for the movement of the adjusting slider 330, ensuring that the adjusting slider 330 can accurately drive the movement of the insert 200; the spring 320 provides elastic force to the adjusting slider 330, enabling the insert 200 to closely cooperate with related components. The spring 320 stores elastic potential energy during normal operation and rapidly releases this energy in case of emergencies, pushing the insert 200 into contact with the pier and generating friction, ensuring the reliability of the fall protection function; the adjusting slider 330, as the connecting and motion execution component, transmits and converts the elastic force of the spring 320 and the external force received by the insert 200. These three components work together to realize the function of the elastic pushing module 300 in the fall protection device 10, ensuring the stable operation and reliable fall protection performance of the device.

[0054] When the equipment malfunction is resolved, the fall arrestor 10 does not need to return to the electromagnet module 400 engaged state. The fall arrestor 10 will only prevent the equipment from falling, not hinder its ascent. Specifically, during ascent, the insert 200 will compress the spring 320 due to friction. At this time, the insert 200 will continue to adhere to the pier column during ascent, but it will not affect the ascent of the equipment. Once the equipment has reached its destination, the spring 320 will be manually compressed to return to its initial state.

[0055] Reference Figure 1 According to the present invention, a fall prevention device 10 is provided, wherein the adjusting slider 330 is provided with a pin hole 331, the fixing seat 100 is provided with a fixing hole 120 corresponding to the pin hole 331, and the safety pin 600 passes through the pin hole 331 and the fixing hole 120 to fix the relative position of the insert 200 and the fixing seat 100.

[0056] It is understood that in this embodiment, the pin hole 331, the fixing hole 120, and the safety pin 600 work together to achieve mechanical locking of the fall arrestor 10. When the self-climbing mechanism 1 needs to be debugged or maintained, the position of the insert 200 can be fixed by the safety pin 600, which increases the convenience of operation; at the same time, it also provides an additional control means, which can prevent the insert 200 from moving under certain circumstances, thereby improving the safety and controllability of the entire system under different working conditions.

[0057] Reference Figure 1 According to the present invention, a fall prevention device 10 also includes a friction plate 700, which is connected to the contact surface of the insert 200 and the pier column.

[0058] Understandably, the main function of the friction plate 700 is to increase the friction between the insert 200 and the pier. In case of emergencies (such as power outages or mechanical failures), the insert 200 contacts the pier under the action of the elastic pushing module 300. By installing the friction plate 700 on the contact surface, the coefficient of friction between the insert 200 and the pier can be significantly increased, thereby more effectively preventing the self-climbing mechanism 1 from falling.

[0059] In some embodiments, the fall arrestor 10 further includes an electric push rod connected to the insert 200, which is used to move the insert 200 downward so that the spring 320 is in a compressed state.

[0060] Understandably, after the electric push rod presses the insert 200 firmly, the electromagnet module 400 attracts the insert 200, and the electric push rod returns to its original position. The electric push rod connects to the insert 200 and drives the insert 200 downward, compressing the spring 320. This process converts electrical energy into the elastic potential energy of the spring 320 for storage. When the fall arrestor 10 needs to function, such as when a fall risk is detected or emergency braking is required, the compressed spring 320 can quickly release its elastic potential energy, pushing the insert 200 to a position that engages with a pier or other obstacle, thereby achieving the fall arrest function.

[0061] In some embodiments, the fall arrestor 10 further includes an electromagnetic induction coil module, which is disposed on the guide rod 310. The electromagnetic induction coil module is used to drive the adjusting slider 330 to move downward to press the insert 200 so that the spring 320 is in a compressed state.

[0062] Understandably, when the electromagnetic induction coil module is energized, a magnetic field is generated around it according to the principle of electromagnetic induction. This magnetic field interacts with the adjusting slider 330 (which is usually made of magnetic material or connected to a magnetic component), generating an electromagnetic force that drives the adjusting slider 330 downward to compress the spring 320 and keep the insert 200 stationary. The downward movement of the adjusting slider 330 compresses the connected spring 320, converting electrical energy into the elastic potential energy of the spring 320 and storing it. In the event of a fall hazard, the spring 320 releases its elastic potential energy, pushing the adjusting slider 330 to quickly move the insert 200 to a position that prevents the self-climbing mechanism 1 from falling, thus achieving the fall prevention function.

[0063] Reference Figure 2This utility model also provides a self-climbing mechanism 1, which includes a frame assembly 20 and the aforementioned anti-fall device 10. The frame assembly 20 encloses a climbing space 21 for passing through the pier. The anti-fall device 10 is installed on the frame assembly 20 and located within the climbing space 21. The specific structure of the anti-fall device 10 is as described in the above embodiments. It is understood that since the aforementioned anti-fall device 10 is used in the self-climbing mechanism 1, the embodiments of the self-climbing mechanism 1 include all the technical solutions of all embodiments of the aforementioned anti-fall device 10, and the achieved technical effects are exactly the same, so they will not be repeated here.

[0064] In one specific embodiment, a frame assembly 20 includes four fall arresters 10, which are symmetrically arranged in pairs on opposite sides of the frame assembly 20. Of course, in other embodiments, a frame assembly 20 may also include other different numbers of fall arresters 10, which is not specifically limited here.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
