Description

Technical Field

[0001] This invention belongs to the field of engineering construction technology, and more specifically, it relates to a safety component for limiting and preventing collisions of suspended platforms. Background Technology

[0002] Suspended platforms are a common and important piece of equipment in construction, providing a foothold for construction workers to work at heights. Workers can operate conveniently inside the suspended platform. For example, when painting the exterior walls of high-rise buildings, workers ride in the suspended platform to reach the appropriate height and carry out painting work on the walls.

[0003] 1. The suspended platform is only equipped with a single layer of simple rubber anti-collision blocks without a graded buffer structure. When there is a collision, the impact force is directly transmitted to the main body of the suspended platform in one go. The instantaneous impact load is large, which can easily cause local deformation of the side wall and bottom frame of the suspended platform, cracking of welds, and denting of plates. Long-term impact can easily lead to structural fatigue damage.

[0004] 2. Construction suspended platforms rely solely on manual visual observation and avoidance, resulting in blind spots during operation and delays in human reaction. After a collision, the crane cannot be stopped immediately. After hitting walls, scaffolding, or building protrusions, the crane continues to rise and fall, causing repeated squeezing and continuous collisions. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides a suspended platform limiting and anti-collision safety component.

[0006] A suspended platform limiting and anti-collision safety component includes a suspended platform frame and L-shaped hanging plates. Each L-shaped hanging plate has a lifting lug fixedly installed at its top. The suspended platform frame has two support seats fixedly installed at its bottom. The component also includes:

[0007] Multiple buffer mechanisms are provided, each of which is located on the outside of the basket frame. Each buffer mechanism includes a force-bearing plate, a rubber pad, and a side plate. Two side blocks are fixedly installed at the top of each side plate, and a movable rod is rotatably connected to the outside of each side block.

[0008] Each of the side plates is slidably mounted with a sleeve frame, and the side plate is movably sleeved inside the sleeve frame. Each of the two side ends of each sleeve frame is provided with a U-shaped round rod, and each U-shaped round rod has a sliding plate on its surface. Each of the two side ends of each sleeve frame is provided with a spring, and each spring is sleeved on the outside of the U-shaped round rod. Each of the two outer side walls of each sleeve frame is provided with a side groove.

[0009] Preferably, the bottom of the suspended basket frame is fixedly connected to two U-shaped round rods, which are symmetrically distributed. The bottom surface of each load-bearing plate is fixedly connected to a base frame, which is movably sleeved on the outer surface of the two U-shaped round rods.

[0010] The two U-shaped round rods are provided with the same sleeve plate. Each of the two sides of the sleeve plate is provided with a spring. Each spring is sleeved on the outer surface of the U-shaped round rod, and the sleeve plate is fixedly sleeved in the middle of the two U-shaped round rods.

[0011] The two sides of the suspended basket frame are fixedly equipped with fixing mechanisms, which include a mounting frame, a sleeve, and a positioning cylinder. Each sleeve has an L-shaped round rod movably mounted on its top end.

[0012] Preferably, each of the mounting frames is a hollow structure, the outer side of the L-shaped hanging plate is connected to the L-shaped round rod by welding, and each of the L-shaped hanging plates is provided with a sliding groove inside;

[0013] Each of the chutes has a rotating shaft rotatably mounted on its inner top wall, a screw is provided on the bottom surface of each rotating shaft, a screw sleeve is threaded onto the outer surface of each screw, and a turntable is fixedly mounted on the outer surface of each rotating shaft.

[0014] Each of the load-bearing plates has a locking socket fixedly installed on its inner wall. Each locking socket is connected to the load-bearing plate by welding. Two limiting sliders are slidably installed on the inner side wall of each locking socket. Each limiting slider has an expansion joint at its end.

[0015] Preferably, each of the locking sockets is provided with a control box inside, an interface end is fixedly installed on the top of each control box, a guide rail plate is fixedly installed on the side end of each control box, a base groove is provided on the inner side of each guide rail plate, and a fixed end piece is provided on the inner side wall of each control box.

[0016] Each of the guide rail plates has a push plate slidably installed inside, and each of the push plates has a moving end piece fixedly installed on both sides. Each moving end piece is made of copper core material and is connected to the push plate by welding.

[0017] Two spring rods are fixedly installed on the side end of each push plate. The two ends of each spring rod are connected to the control box and the push plate by welding. The spring rods are made of stainless steel.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] In this invention, a rubber pad serves as the direct impact-bearing layer, transferring kinetic energy to the load-bearing plate and the base frame. The base frame is fitted onto the second U-shaped rod and slides along the rod towards the basket frame, compressing the first spring to convert kinetic energy into elastic potential energy, thus limiting the horizontal displacement of the load-bearing plate. The load-bearing plate drives the side plate to slide along the inner wall of the frame, with the side block embedded in the side groove of the frame. The side block slides linearly, and when it moves, it drives the movable rod to rotate around the pin, converting the horizontal displacement into the axial displacement of the sliding plate, compressing the second spring to further absorb the impact kinetic energy. This dual-stage buffer structure can absorb the impact kinetic energy in stages, significantly reducing the impact force on the basket frame and preventing structural deformation and cracking.

[0020] In this invention, when the force plate moves towards the suspended basket frame due to a collision, it drives the locking socket and control box to move synchronously. The push plate slides inward along the guide rail groove under the reaction force, squeezing the spring rod. When the push plate slides, it causes the moving end piece and the fixed end piece to separate, the circuit is broken, the control box detects the circuit interruption, and transmits a stop command to the crane through the interface. The crane immediately stops its lifting and lowering actions, realizing instantaneous stop linkage at the moment of collision, avoiding continuous collisions of the suspended basket frame with obstacles, and reducing the risk of collision damage and safety accidents.

[0021] In this invention, the rotating turntable drives the rotating shaft to rotate coaxially, and the screw rotates synchronously with the rotating shaft. The screw sleeve moves up and down along the screw shaft through thread transmission, driving the sleeve to slide along the L-shaped round rod. When the sleeve is inserted into the positioning cylinder, the L-shaped hanging plate is locked and cannot move up and down. Rotating the turntable in the opposite direction can unlock it and adjust the position of the hanging plate, realizing the adjustable rigid locking of the L-shaped hanging plate and the hanging basket frame. This prevents the hanging plate from moving up and down during the hoisting process, ensures stable power transmission of the lifting lugs, and prevents the hanging basket frame from tilting or falling due to the displacement of the hoisting components.

[0022] In this invention, a locking socket is welded to the inner wall of a load-bearing plate. The control box is installed inside the socket, and a guide rail plate is driven to engage with the socket cavity. The guide rail plate presses against the inner limit slider, compressing the spring inside the telescopic joint. After the guide rail plate is in place, the spring rebounds and pushes the limit slider to slide in the opposite direction, inserting it into the slot at the side end of the guide rail plate to achieve a snap-fit ​​fixation. During disassembly, only reverse force needs to be applied to compress the spring inside the telescopic joint and disengage the limit slider from the slot, completing the quick disassembly of the control box. This enables the control box to be installed and disassembled quickly without fasteners, facilitating maintenance and replacement. Attached Figure Description

Detailed Implementation

[0030] Example 1

[0031] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0032] Please see Figure 1 - Figure 6 This invention provides a suspended basket limiting and anti-collision safety component, including a suspended basket frame 1 and L-shaped hanging plates 4. Each L-shaped hanging plate 4 has a lifting lug 5 fixedly installed on its top. Two support seats 6 are fixedly installed on the bottom of the suspended basket frame 1. The L-shaped hanging plates 4 are placed in the preset installation positions on the side of the suspended basket frame 1 according to the design quantity (two on each side of the suspended basket frame 1) to complete the initial alignment of the L-shaped hanging plates 4 with the suspended basket frame 1. The lifting lug 5 is fixed on the top end face of each L-shaped hanging plate 4 by welding / bolt fastening. The lifting lug 5 is used to connect the lifting traction equipment and transmit the lifting power of the suspended basket frame 1. Two support seats 6 are fixedly installed at symmetrical preset points at the bottom of the suspended basket frame 1 to improve the structural stability of the bottom of the suspended basket frame 1 and assist in bearing the bottom load of the buffer mechanism 2.

[0033] Multiple buffer mechanisms 2 are provided, each located on the outer side of the suspended basket frame 1. Each buffer mechanism 2 includes a load-bearing plate 201, a rubber pad 207, and a side plate 2010. Two side blocks 209 are fixedly installed at the top of each side plate 2010, and a movable rod 2014 is rotatably connected to the outer side of each side block 209. Multiple buffer mechanisms 2 are symmetrically arranged on the front and rear outer side walls of the suspended basket frame 1, serving as the core anti-collision buffer component of the suspended basket frame 1. The rubber pad 207 is fixed to the load-bearing plate 2 by adhesive / bolt. 01 The outer surface serves as a flexible buffer layer that directly bears the force during a collision. The side plate 2010 is vertically fixed to the side of the load-bearing plate 201 near the basket frame 1 to form a collision force transmission structure. Two side blocks 209 are symmetrically fixed to the outer side of the top of each side plate 2010 to ensure that the side blocks 209 are firmly connected to the side plate 2010 without loosening. One end of the movable rod 2014 is rotatably connected to the outside of the side block 209 through a pin. The movable rod 2014 can rotate freely around the connection point to transmit the displacement force of the side block 209.

[0034] Each side plate 2010 is slidably fitted with a frame 202, with the side plate 2010 movably sleeved inside the frame 202. Each frame 202 has a U-shaped rod 203 at each of its two ends, and a sliding plate 2012 on the surface of each U-shaped rod 203. Each frame 202 also has a spring 2013 at each of its two ends, with each spring 2013 sleeved on the outside of the U-shaped rod 203. Each frame 202 has side grooves 2011 on its two outer walls. The frame 202 is fixed to the outer wall of the suspended basket frame 1, serving as a sliding guide for the side plate 2010. The side plate 2010 is movably sleeved inside the frame 202, ensuring that the side plate 2010 can slide smoothly and linearly along the inner wall of the frame 202. U-shaped round rods 203 are fixed at both ends of the frame 202 as guide supports for spring 2013 and slide plate 2012. Spring 2013 is sleeved on the outside of U-shaped round rod 203. One end of spring 2013 is fixed to the side end of the frame 202, and the other end is connected to slide plate 2012 to form an elastic buffer structure. Side block 209 on side plate 2010 is embedded into side groove 2011 on the outer wall of frame 202. Side block 209 can slide linearly along side groove 2011 to limit the sliding trajectory of side plate 2010. The end of movable rod 2014 away from side block 209 is rotatably connected to slide plate 2012 on U-shaped round rod 203 to realize the linkage between the displacement of side block 209 and slide plate 2012 and spring 2013.

[0035] Two U-shaped round rods 208 are fixedly connected to the bottom of the suspended basket frame 1. The two U-shaped round rods 208 are symmetrically distributed. A base frame 204 is fixedly connected to the bottom surface of each load-bearing plate 201. The base frame 204 is movably sleeved on the outer surface of the two U-shaped round rods 208. The two U-shaped round rods 208 are fixed at symmetrical positions at the bottom of the suspended basket frame 1. The two rods are parallel and symmetrically distributed, serving as bottom buffer guide rods. The base frame 204 is vertically fixed at the center of the bottom surface of the load-bearing plate 201 to ensure that the load-bearing plate 201 and the base frame 204 move synchronously. The base frame 204 is movably sleeved on the outside of the two U-shaped round rods 208. The base frame 204 can slide linearly along the rods of the U-shaped round rods 208 to constrain the displacement direction of the bottom of the load-bearing plate 201.

[0036] Two U-shaped round rods 208 have the same sleeve plate 206 on their surfaces. Springs 205 are provided at both ends of the sleeve plate 206. Each spring 205 is sleeved on the outer surface of the U-shaped round rod 208. The sleeve plate 206 is fixedly sleeved in the middle of the two U-shaped round rods 208 to keep the distance between the two U-shaped round rods 208 stable. As a fixed support for the springs 205, the two springs 205 are respectively sleeved on the outer surface of the two U-shaped round rods 208. One end of the spring 205 is fixed to the side end of the sleeve plate 206, and the other end is fixed to the inner side wall of the base frame 204 to form a bottom elastic buffer structure. The springs 205 are pre-tightened to ensure that the springs 205 are in a natural extension and contraction state when there is no collision, and can be effectively compressed and rebounded when subjected to force.

[0037] Fixing mechanisms 3 are fixedly installed on both sides of the suspended basket frame 1. The fixing mechanism 3 includes a mounting frame 301, a sleeve 308, and a positioning cylinder 309. An L-shaped round rod 306 is movably installed on the top of each sleeve 308. The fixing mechanism 3, which is installed on the left and right sides of the suspended basket frame 1, corresponds to the L-shaped hanging plate 4. It serves as a fastening connection component between the L-shaped hanging plate 4 and the suspended basket frame 1. The mounting frame 301 is fixed to the outer wall of the side end of the suspended basket frame 1. The mounting frame 301 has a hollow structure to provide insertion space for the L-shaped hanging plate 4. The positioning cylinder 309 is fixed on the top end face of the mounting frame 301 as a positioning and locking carrier for the sleeve 308. The sleeve 308 is movably sleeved on the outer side of the top of the L-shaped round rod 306. The sleeve 308 can slide freely up and down along the L-shaped round rod 306.

[0038] Each mounting frame 301 is a hollow structure. The outer side of the L-shaped hanging plate 4 is connected to the L-shaped round rod 306 by welding. Each L-shaped hanging plate 4 has a sliding groove 307 inside. The L-shaped hanging plate 4 is inserted along the hollow structure of the mounting frame 301. The L-shaped hanging plate 4 can slide up and down inside the mounting frame 301 to complete the initial insertion and positioning. The L-shaped round rod 306 is fixed to the outer wall of the L-shaped hanging plate 4 by full welding to ensure that the connection is not loose or displaced. The sliding groove 307 is processed at a preset position inside each L-shaped hanging plate 4 to provide installation and sliding space for the screw 303 and the screw sleeve 302 to ensure the normal operation of the internal components.

[0039] Each groove 307 has a rotating shaft 304 rotatably mounted on its inner top wall. Each rotating shaft 304 has a screw 303 on its bottom surface, and a threaded sleeve 302 is threaded onto the outer surface of each screw 303. A turntable 305 is fixedly mounted on the outer surface of each rotating shaft 304. The rotating shaft 304 is rotatably mounted on the inner top wall of the groove 307, allowing it to rotate freely around its own axis without jamming. The top of the screw 303 is fixedly connected to the bottom surface of the rotating shaft 304, so that the rotation of the rotating shaft 304 synchronously drives the screw 303 to rotate coaxially. The screw sleeve 302 is threaded onto the outer surface of the screw rod 303. When the screw rod 303 rotates, the screw sleeve 302 moves linearly up and down along the screw rod 303. The screw sleeve 302 is fixedly sleeved with the sleeve 308 to achieve linkage. The turntable 305 is fixedly installed on the outer surface of the rotating shaft 304. By rotating the turntable 305, the rotating shaft 304 and the screw rod 303 can be manually driven to rotate. Rotating the turntable 305 adjusts the position of the screw sleeve 302 to ensure that the sleeve 308 can be smoothly inserted into the positioning cylinder 309 to complete the locking. Reverse rotation can pull it out to unlock.

[0040] Each load-bearing plate 201 has a locking socket 7 fixedly installed on its inner wall. Each locking socket 7 is connected to the load-bearing plate 201 by welding. Two limit sliders 72 are slidably installed on the inner side wall of each locking socket 7. Each limit slider 72 has a telescopic joint at its end. By sliding the control box 73, the control box 73 is aligned with the inside of the locking socket 7. The control box 73 contains a control main board and a drive power supply. The control box 73 is placed inside the locking socket 7. The control box 73 drives the guide rail plate 75 to engage with the inside of the locking socket 7. The guide rail plate 75 presses the limit sliders 72 to slide. The limit sliders 72 press the telescopic joint. The telescopic joint contains a spring. When the control box 73 and the guide rail plate 75 are installed in place, the telescopic joint pushes the limit sliders 72 to slide in the opposite direction. The limit sliders 72 slide to the side end of the guide rail plate 75 and insert into the inside of the guide rail plate 75. This allows for quick assembly and installation.

[0041] Each locking socket 7 has a control box 73 inside. Each control box 73 has an interface end 74 fixedly installed on its top. Each control box 73 has a guide rail plate 75 fixedly installed on its side end. Each guide rail plate 75 has a base groove on its inner side. Each control box 73 has a fixed end piece 71 on its inner side wall. The fixed end pieces 71 are connected to the control box 73 through wires. The push plate 78 slides inside the guide rail plate 75. The two sides of the push plate 78 have a protruding structure, allowing the push plate 78 to slide along the guide rail plate 75.

[0042] Each guide rail plate 75 has a push plate 78 slidably installed inside. Each push plate 78 has a moving end piece 77 fixedly installed on both sides. Each moving end piece 77 is made of copper core material. The moving end piece 77 is connected to the push plate 78 by welding. The moving end piece 77 is attached to the fixed end piece 71 to form a complete circuit. When the push plate 78 slides inside the guide rail plate 75, the push plate 78 drives the moving end piece 77 to slide away from the fixed end piece 71. The moving end piece 77 and the fixed end piece 71 are disconnected, and the circuit is blocked. The signal is transmitted through the control circuit board inside the control box 73. The connection is made to the interface terminal 74 and the crane equipment through the wire. When the basket frame 1 is hit, the control box 73 transmits a signal to the crane to stop the movement in time.

[0043] Two spring rods 76 are fixedly installed on the side end of each push plate 78. The two ends of each spring rod 76 are connected to the control box 73 and the push plate 78 by welding. The spring rods 76 are made of stainless steel. Through the sliding of the force plate 201, the control box 73 and the push plate 78 move synchronously. The control box 73 drives the push plate 78 to move towards the side end of the basket frame 1. The top of the push plate 78 is pressed and slides inside the guide plate 75. The push plate 78 squeezes the two spring rods 76, and the spring rods 76 are compressed inside the guide plate 75.

[0044] Example 2

[0045] This embodiment specifically discloses a suspended platform limiting and anti-collision safety component, including the following steps:

[0046] First, an L-shaped hanging plate 4 is placed at a pre-set mounting position on the side of the suspended basket frame 1. A lifting lug 5 (for connecting the lifting and traction equipment) is fixed to the top by welding / bolts. Support seats 6 are symmetrically installed at the bottom to assist in bearing the bottom load of the buffer mechanism 2. A mounting frame 301 is fixed to the outer wall of the side end of the suspended basket frame 1 (providing an insertion cavity for the L-shaped hanging plate 4). A positioning cylinder 309 is fixed to the top end face of the mounting frame 301. A sleeve 308 is movably sleeved on the outside of an L-shaped round rod 306 (the L-shaped round rod 306 is welded to the outer wall of the L-shaped hanging plate 4 and moves synchronously with the hanging plate). A rotating turntable 305 drives the rotating shaft 304 on the inner top wall of the slide groove 307 to rotate. The screw 303 on the bottom surface of the rotating shaft 304 rotates synchronously and coaxially. A threaded sleeve 302 is threaded onto the screw 303 and moves up and down axially with the rotation of the screw 303, causing the sleeve 308 to slide along the L-shaped round rod 306. When the sleeve 308 moves down and inserts into the positioning cylinder... At position 309, the L-shaped hanging plate 4 is locked inside the mounting frame 301 and cannot slide up or down, thus completing the rigid fixation of the hoisting mechanism. Rotating the turntable 305 in the opposite direction, the sleeve 308 pulls out the positioning cylinder 309, which unlocks the hanging plate and allows for position adjustment. After the lifting lug 5 is connected to the lifting traction equipment, the power is transmitted to the basket frame 1 through the lifting lug 5, the L-shaped hanging plate 4, and the mounting frame 301. The support seat 6 disperses the bottom load, preventing the buffer mechanism 2 from directly bearing the hoisting stress. When the basket frame 1 is placed on the ground / platform, the support seat 6 directly contacts the support surface, bearing the weight of the basket and the bottom load of the buffer mechanism 2, preventing the U-shaped round rod 208 from scraping and deforming against the ground. In the hoisting state, the support seat 6 disperses the hoisting stress at the bottom of the basket to the entire bottom frame, preventing local stress concentration at the bottom from causing deformation. At the same time, it assists in bearing the vibration load transmitted by the buffer mechanism 2, reducing the impact of the buffer mechanism 2 on the main body of the basket.

[0047] Rubber pad 207 uses a special adhesive for neoprene rubber. The preload of spring 205 is 150±30, and the preload of spring 2013 is 80±20. U-shaped round rod 203 and U-shaped round rod 208 are both made of metal steel. The sleeve frame 202 and the side plate 2010 are clearance-fitted with a clearance of 0.02 to 0.05 mm on one side. The inner wall is inlaid with a polytetrafluoroethylene wear-resistant bushing to reduce the sliding resistance of the side plate 2010 and prevent jamming. The movable rod 2014 is made of stainless steel. The pin shaft and the pin shaft holes of the side block 209 and the slide plate 2012 are clearance-fitted. Elastic retaining rings are installed at both ends of the pin shaft. The retaining rings are inserted into the annular groove at the end of the pin shaft to prevent the pin shaft from coming out. The screw 303 and the screw sleeve 302 use trapezoidal threads. The trapezoidal threads have strong self-locking properties and are suitable for axial locking conditions.

[0048] The inner top wall of the slide groove 307 has a pre-set bearing seat for installing a deep groove ball bearing. The rotating shaft 304 is interference-fitted with the inner ring of the bearing. The side of the turntable 305 has a radial threaded hole for installing a set screw. When tightened, the screw presses against the outer wall of the rotating shaft 304, restricting the rotation of the turntable 305. The lower part of the inner wall of the positioning cylinder 309 has an annular groove. The corresponding position on the outer wall of the sleeve 308 is installed with elastic steel balls. After the sleeve 308 is inserted, the steel balls are locked into the groove, and the axial anti-disengagement force is ≥500N. At the same time, the self-locking property of the trapezoidal thread is utilized so that the screw sleeve 302 will not move in the opposite direction when there is no external force, providing double anti-disengagement.

[0049] After the rubber pad 207 contacts the obstacle, the impact force is transmitted through the force plate 201 to the base frame 204 on the bottom surface. The base frame 204 is sleeved on two parallel and symmetrical U-shaped round rods 208 and slides along the rods towards the basket frame 1. Spring 205 is sleeved on the outside of the U-shaped round rods 208, with one end fixed to the sleeve plate 206 (fixed in the middle of the U-shaped round rods 208) and the other end fixed to the inside of the base frame 204. When the base frame 204 slides, it compresses the spring 205, converting the impact kinetic energy into the elastic potential energy of the spring, limiting the horizontal displacement of the force plate 201, and achieving first-level buffering. When the force plate 201 moves, it drives the inner side plate 2010 to slide synchronously. The side plate 2010 is sleeved in the sleeve frame 202 (fixed to the outer wall of the basket frame 1), and the side block 209 is embedded in it. The side block 209 slides linearly along the side groove 2011 of the sleeve frame 202, restricting the offset trajectory of the side plate 2010. When the side block 209 moves, it drives the movable rod 2014, which is hinged at both ends, to rotate around the pin. The other end of the movable rod 2014 is connected to the slide plate 2012 (sleeved on the U-shaped round rod 203), which converts the horizontal displacement of the side block 209 into the axial displacement of the slide plate 2012, compressing the spring 2013, which is sleeved on the outside of the U-shaped round rod 203, to absorb the kinetic energy of the side collision and achieve secondary buffering. After the collision force disappears, the spring 2013 rebounds, pushing the slide plate 2012 to move in the opposite direction. The movable rod 2014 drives the side block 209 and the side plate 2010 to reset, and works with the bottom spring 205 to achieve the synchronous reset of the force plate 201.

[0050] The second step involves welding the locking socket 7 to the inner wall of the load-bearing plate 201, aligning the control box 73 with the inside of the socket, and driving the guide rail plate 75 to snap into the socket cavity. The guide rail plate 75 presses against the inner limit slider 72, compressing the spring in the telescopic joint. After the guide rail plate 75 is installed in place, the spring rebounds and pushes the limit slider 72 to slide in the opposite direction and insert into the slot at the side end of the guide rail plate 75, achieving fastener-free quick snap-fit ​​fixation. In the initial state of the circuit: the push plate 78 is installed along the base groove of the guide rail plate 75, with the protrusions on both sides cooperating with the base groove guide. The two ends of the spring rod 76 are welded to the push plate 78 and the control box 73. In the pre-tightened state, the push plate 78 maintains its initial position. The moving end piece 77 of the copper core material is attached to the fixed end piece 71 inside the control box 73, the circuit is conductive, and the crane can operate normally. The interface end 74 is connected to the crane control system through a wire to transmit the stop signal.

[0051] An internal compression spring is installed in the expansion joint. One end of the spring (205) is fixed to the inner wall of the locking socket 7, and the other end is connected to the tail of the limit slider 72. The control box 73 is made of ABS engineering plastic, and a nitrile rubber sealing ring is set at the joint. It is a normally closed control circuit. Under normal working conditions, the fixed end plate 71 and the moving end plate 77 are in contact, the circuit is connected, and the crane control system receives the "allow operation" signal. In case of collision, the moving end plate 77 separates from the fixed end plate 71, the circuit is broken, the crane triggers the stop protection, the passive relay contact outputs (normally closed contact), there is no digital signal transmission, and it is directly connected to the crane emergency stop control circuit. It is connected through a two-core shielded cable. The two ends of the cable are crimped terminals and connected in series with the crane emergency stop circuit. The interface end 74 is a waterproof aviation plug. The fixed end plate 71 and the moving end plate 77 are provided by the pre-tightening force of the spring rod 76. The contact pressure is ≥8N to ensure reliable circuit conduction.

[0052] When the force plate 201 moves towards the basket frame 1 due to a collision, it drives the locking socket 7 and the internal control box 73 to move synchronously. The outer end of the push plate 78 is subjected to a reaction force (or slides inward relative to the guide rail plate 75), moves along the base groove of the guide rail plate 75 and squeezes the spring rod 76. The spring rod 76 is compressed and stores energy. When the push plate 78 slides, it causes the moving end piece 77 to separate from the fixed end piece 71, the circuit is broken, the control circuit board in the control box 73 detects the signal interruption, and transmits a stop command to the crane through the interface terminal 74. The crane immediately stops lifting and lowering to prevent continuous collision. After the collision force disappears, the spring 1 205 and the spring 2 2013 drive the force plate 201 to reset, the push plate 78 loses external force, the spring rod 76 rebounds and pushes the push plate 78 to reset, the moving end piece 77 re-attaches to the fixed end piece 71, the circuit is restored, and the crane can restart operation.
