Description

Technical Field

[0001] The invention relates to the technical field of conveying devices, and in particular to a suspended anti-falling conveying device. Background Art

[0002] High-altitude construction work is an inevitable and important part of the construction process, especially in the construction of high-rise buildings and large structures. The transportation of materials and tools has an important impact on the construction progress and safety. Traditional transportation methods, such as cranes and manual handling, have problems such as low efficiency and potential safety hazards. In order to improve the safety and efficiency of high-altitude material transportation, the suspended anti-fall conveying device came into being. It transports materials from the ground to the high-altitude operation area through a suspension system, greatly reducing the risk of manual handling and improving construction efficiency.

[0003] The existing suspended anti-falling conveying device usually includes components such as a track system, a conveying vehicle and an anti-falling device. The track system is installed on the building structure, and the conveying vehicle runs on the track and suspends and transports materials through a connecting device. The anti-falling device is used to prevent the conveying vehicle or materials from accidentally falling during transportation. The track system often drives the hanging basket up and down through the hoist above. However, when working at high altitude, a series of dangerous problems such as steel cable breakage and hoist stopping working may occur, which may easily cause the hanging basket to fall. The existing suspended anti-falling conveying device will use protective measures such as safety locks to visually detect whether the steel cable is broken, and prevent falling after the safety lock reacts. However, the response speed of visual detection relative to the detection of tension sensors will have a slight delay, and when the steel cable of the current suspended anti-falling conveying device breaks or falls off from the hoist, the two-way lifting position becomes a one-way lifting position, which may easily cause the hanging basket to flip over, and the transported materials may be thrown out of the hanging basket, thereby affecting the safety of transportation.

[0019] See also Figures 1 to 9The embodiment of the present invention provides an aerial work device. The anti-falling conveying device is used in the scene of suspension lifting when conveying vehicles or materials. In this embodiment, the structure of the anti-falling conveying device is improved to have the advantages of anti-falling or anti-overturning. Specifically, taking the work of material transportation as an example, as a preferred solution in this embodiment, the anti-falling conveying device is specifically a suspended anti-falling conveying device, which can decelerate and stop in the event of an accident, thereby playing an anti-falling effect.

[0020] See also Figures 1 to 9 The present invention provides a technical solution: a suspended anti-falling conveying device, which is mainly used in the scenario of suspended lifting during conveying vehicles or material transportation.

[0021] The suspended anti-falling conveying device comprises a steel cable 3, a guiding mechanism 4, a slow-down mechanism 5, a bearing mechanism 6 and a driving mechanism 2 for winding the steel cable 3, wherein: The driving mechanism 2 is preset at the top of the building wall 1, one end of the steel cable 3 is fixedly connected to the fixed end of the driving mechanism 2, and the other end is arranged at the winding end of the driving mechanism 2; The guiding mechanism 4 includes a fixing plate 401, a positioning plate 406, an auxiliary wheel 4010, a positioning wheel 404 and two guide wheels 407. The positioning plate 406 is fixedly connected to the top of the fixing plate 401. The two guide wheels 407 are sequentially arranged at intervals at the bottom of the positioning plate 406 along the first direction. The positioning wheel 404 and the auxiliary wheel 4010 are sequentially arranged at intervals at the top of the fixing plate 401 along the first direction. The spacing between the positioning wheel 404 and the auxiliary wheel 4010 is greater than the spacing between the two guide wheels 407. The surface of the positioning plate 406 is provided with two avoidance openings corresponding to the two guide wheels 407. After passing through one of the avoidance openings, the middle portion of the steel cable 3 is contacted and connected with one of the guide wheels 407, the positioning wheel 404, the auxiliary wheel 4010, and the other guide wheel 407 in sequence, and passes out through the other avoidance opening. The slow-down mechanism 5 is arranged on the positioning plate 406, and the locking end of the slow-down mechanism is connected to the middle part of the steel cable 3 above the two avoidance openings, and is used to clamp and position the middle part of the steel cable 3. A tension detection mechanism is arranged on the steel cable 3; The carrying mechanism 6 is arranged below the fixed plate 401 to provide storage space; In this embodiment, through the coordinated setting between the driving mechanism 2 and the steel cable 3, one end of the steel cable 3 can be fixed, and the other end of the steel cable 3 can be reeled in, so that the steel cable 3 can drive the guiding mechanism 4 below to move up and down, and the working intensity of the driving mechanism 2 can be reduced by means of the principle of the movable pulley, so as to ensure the working stability and life of the driving mechanism 2. Through the setting of the guiding mechanism 4, the position of the steel cable 3 can be fixed to the top of the supporting mechanism 6 close to the building by means of the positioning plate 406, so that even if the steel cable 3 breaks or falls off from the hoist, the position of the steel cable 3 for the overall suspension of the supporting mechanism 6 can still be guaranteed to remain unchanged, so that the force on the supporting mechanism 6 does not change, thereby reducing the risk of overturning, and the guide wheel 407 and the auxiliary wheel 4010 can guide the steel cable 3, so that the steel cable 3 The two force points are respectively located on the side of the top of the supporting mechanism 6 close to the building and the side away from the building, thereby ensuring the stability of the supporting mechanism 6 during the suspension process. With the help of the descending mechanism 5, in the event of an accident, that is, one end of the middle part of the steel cable 3 breaks, the steel cable 3 can be locked. Since it is arranged above the positioning plate 6, the two ends of the middle part of the steel cable 3 can be effectively clamped at the same time to maintain the triangular traction shape, thereby avoiding the load-bearing mechanism from overturning or tilting due to a large deviation of the center of gravity, which may cause safety hazards. The stable structure reduces the swing of the load-bearing mechanism caused by wind or other external factors during work, thereby improving work efficiency and operating comfort. The uniform force distribution makes the load-bearing mechanism run more smoothly, reduces vibration and noise, especially for the operation scenario of cleaning the outer glass of the building, to avoid noise and affect indoor personnel. The tension detection mechanism can be used to timely detect whether the steel cable is broken. When one end of the middle part of the steel cable 3 is broken, the descending mechanism 5 can respond in time to clamp the steel cable to prevent it from falling. The steel cable 3, that is, the cable used by the hanging basket, is used to detect the cable tension, that is, to detect the tension of the steel cable 3.

Through the setting of the guide wheel 205, the steel cable 3 can be assisted in movement, thereby reducing the wear of the steel cable 3, and at the same time, the movement of the steel cable 3 can also be guided to reduce entanglement.

[0024] In the above embodiment, as a preferred solution, the guiding mechanism 4 further includes a positioning frame 402, a fixing seat 403, a limiting wheel 405, a limiting rod 408 and a limiting hole 409.

By setting the fixing plate 401, a stable installation position can be provided for the fixing seat 403, and the slow-down mechanism 5 and the bearing mechanism 6 can also be ensured. The connection stability is improved, and then after the steel cable 3 passes through the positioning plate 406, it can be guided by the guide wheel 407 and the auxiliary wheel 4010, pass through between the positioning wheel 404 and the limiting wheel 405, and then pass through the positioning plate 406 again, so that the position where the steel cable 3 passes in and out is on one side above the carrying mechanism 6, and the positioning wheel 404 can set the force of the steel cable 3 on both sides of the top of the carrying mechanism 6, thereby ensuring the suspension stability of the carrying mechanism 6, and the position of the positioning plate 406 can be adjusted through the connection between the positioning plate 406 and the positioning frame 402, so as to adjust the position of the traction center of gravity and improve the stability of the carrying mechanism 6; The positioning plate 406 and the positioning frame 402 can be set to be slidably connected, and a worm, a spirit level and a driving component are set on the positioning frame 402 or the positioning plate 406. The spirit level is used to detect the force on the bearing mechanism after the fracture, and the driving component controls the rotation of the worm to make the position between the positioning frame 402 and the positioning plate 406 move relatively, thereby adjusting the center of gravity position of the force traction, effectively improving stability.

[0025] In the above embodiment, as a preferred solution, the slow-descent mechanism 5 includes two brackets 501, two pressure plates 503 and a plurality of fastening wheels 504. The two brackets 501 are respectively arranged on both sides above the positioning plate 406. The two pressure plates 503 can be slidably connected between the two brackets 501. The plurality of fastening wheels 504 can be rotatably connected to the outer walls of the brackets 501 and the pressure plates 503 and correspond to the steel cables 3 to clamp and position the steel cables 3. The bracket 501 and the pressure plate 503 can move relative to each other, and the multiple fastening wheels 504 are staggered with each other to appropriately compress the steel cable 3, thereby controlling the passing speed of the steel cable 3 within an appropriate range. If the upper steel cable 3 breaks or falls off from the hoist, the degree of compression of the fastening wheel 504 can be increased, thereby controlling the moving speed of the steel cable 3, achieving the effect of deceleration and braking, thereby improving the stability and safety of the device, and the multiple fastening wheels 504 can simultaneously lock multiple positions of the steel cable 3 when being compressed, and the vertical projections of the multiple fastening wheels 504 are staggered with each other to disperse the pressure, reduce the wear of a single fastening wheel 504, and also improve the clamping stability, and the fastening wheels 504 can also limit the moving path of the steel cable 3, reduce the risk of slippage and deviation, thereby ensuring that the steel cable 3 can stably pull the bearing mechanism 6; Alternatively, a control method may be selected in which multiple fastening wheels 504 are directly pressed against the steel cable 3 to lock the steel cable 3 to achieve a braking stop. The slow-down mechanism 5 also includes a guide rod 502, a support seat 505 and a bidirectional hydraulic rod 506.

Bidirectional hydraulic rods 506 are fixedly installed above and below the two pressure plates 503. One of the bidirectional hydraulic rods 506 is fixedly installed on the top of the support seat 505. Through the setting of the guide rod 502, the relative position between the two brackets 501 can be ensured. While ensuring stability, it can also assist in guiding the sliding direction of the pressure plate 503, thereby ensuring that the pressure plate 503 can slide in coordination with the bracket 501, so that the fastening wheel 504 can accurately clamp and limit the steel cable 3, and the two-way hydraulic rod 506 can push the pressure plate 503, providing power and support for the mutual clamping and cooperation of the fastening wheels 504. When the steel cable 3 breaks or falls off from the hoist, the two-way hydraulic rod 506 simultaneously clamps the two pressure plates 503, and then cooperates with the bracket 501, and achieves deceleration by means of the compression between multiple fastening wheels 504.

[0026] In the above embodiment, as a preferred scheme, the supporting mechanism 6 includes a fixed column 601, a support plate 602 and a protective rod 603.

[0027] In the above embodiment, as a preferred scheme, the top of the fixed column 601 is fixedly connected with a connecting rod 8, and one end of the connecting rod 8 passes through the fixed plate 401 and is threadedly connected to a limiting nut 9. Through the setting of the connecting rod 8, one end can be fixed to the top of the fixed column 601, and the other end passes through the fixed plate 401 and then cooperates with the limiting nut 9 to ensure the connection stability between the fixed column 601 and the fixed plate 401, while also facilitating disassembly for transportation and inspection and maintenance.

[0029] The tension detection mechanism includes a tension sensor and a control module. The tension sensor is arranged on the steel cable 3 and the output end is electrically connected to the control module. The output end of the control module is electrically connected to the driving end of the bidirectional hydraulic rod 506. The tension sensor is a known technology. The tension sensor is installed on the steel cable to monitor the tension of the steel cable in real time. When the tension suddenly drops below the threshold, it is determined to be broken and an alarm is triggered. The alarm signal is transmitted to the control module, and the control module controls the driving end of the bidirectional hydraulic rod 506 to operate. A weak current can also be applied to the control module and the two ends of the steel cable. When the circuit breaks, it will be disconnected and an alarm will be triggered. The control module receives the electrical signal of the weak current circuit. When it is disconnected, it controls the driving end of the two-way hydraulic rod 506 to operate. The two-way hydraulic rod 506 is an existing well-known technology and is only used for reference. Its purpose is to drive multiple fastening wheels 504 to compress the steel cable 3 to achieve braking and anti-falling.

[0030] In the present invention, the working steps of the device are as follows: 1. First, fix the fixing clamp 201 to the outside of the building wall 1, and then rotate the adjusting rod 206 to press the end of the fixing clamp 201 against the building wall 1, thereby ensuring the stability of the fixing clamp 201, and then reel and release the steel cable 3, thereby driving the guiding mechanism 4 to rise or fall; 2. Secondly, the conveying vehicle or the conveyed material moves on the support plate 602, and the rotation of the motor 204 can drive the wire wheel 203 to rotate, thereby adjusting the height of the carrying mechanism 6. When rising and falling, it can contact the building wall 1 with the help of the roller 702, which can reduce the resistance and form a relatively stable support. The conveying vehicle or the conveyed material can be lifted and transported along with the carrying mechanism; 3. Then, if the steel cable 3 breaks or falls off from the hoist, the compression degree of the two-way hydraulic rod 506 is increased, so that the multiple fastening wheels 504 compress the steel cable 3, slowing down the speed of the steel cable 3, and then achieving deceleration and braking. By adjusting the compression degree of the two-way hydraulic rod 506, the bearing mechanism 6 can be slowly lowered until it lands on the ground or the steel cable 3 is braked to wait for maintenance.
