Description

Technical Field

[0001] The invention relates to the technical field of steel box girder hoisting, in particular to hoisting equipment with anti-collision function for viaduct steel box girders. Background Art

[0002] At present, the demand for urban public transportation systems is growing, and urban expressway reconstruction is the most important way to utilize urban ground space. Their construction and use play an important role in alleviating urban traffic pressure and improving urban operation efficiency.

[0003] Urban road reconstruction and expansion projects pursue high quality, rapidity, refinement, and safety. Therefore, most urban expressway reconstruction and expansion projects use steel box girders that can be factory-produced, fast to construct, and environmentally friendly. Steel box girders are mostly installed by on-site hoisting operations. Hoisting equipment often fails to detect safety hazards on site in a timely manner due to manual monitoring, resulting in major safety accidents and posing a great threat to the lives of construction workers. When an obstacle is hit due to uncontrollable factors, the steel box girder will be deformed and damaged due to the collision, which will make it unusable, resulting in a waste of resources and increased construction costs. In order to solve the above problems, we need a hoisting device with anti-collision function for viaduct steel box girders. Summary of the invention

[0004] The purpose of the present invention is to provide a hoisting device with anti-collision function for a viaduct steel box girder to solve the problems raised in the prior art.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] The hoisting equipment includes an information receiving feedback box, a decoding converter, a signal receiver, a host, a display, a solar panel, a battery, an airbag module, a buffer inflation module and a steel box beam. The information receiving feedback box is fixedly connected to the outer surface of the airbag module, the decoding converter is electrically connected to the information receiving feedback box, one of the signal receivers is electrically connected to the decoding converter, the positive and negative poles of the battery are electrically connected to the decoding converter, the solar panel is electrically connected to the battery, the other signal receiver is electrically connected to the host, the two signal receivers are connected, the host is electrically connected to the display, and the airbag module is electrically connected. There are multiple groups of airbag modules, and the multiple groups of airbag modules radially wrap the steel box girder. The airbag modules in each group are connected by snap buckles, and buffer inflation modules are provided at both ends and the middle section of each group of airbag modules. Part of the inflation port of each group of airbag modules and the air outlet of the buffer inflation module are connected by a hose, and each group of airbag modules is fixedly connected to the buffer inflation module, and the buffer inflation module is fixedly connected to the steel box girder. The buffer inflation module is arranged at both ends and the middle section of the steel box girder, and the buffer inflation module is located between the steel box girder and the airbag module. Each group of airbag modules and buffer inflation module are located between the two axial end faces of the steel box girder.

[0007] When using the lifting equipment, first connect the airbag module with the buffer inflation module, then lift the steel box girder off the ground, and connect the buffer inflation module to the steel box girder. After the connection is completed, inflate the airbag module until it meets the airbag use standards. Finally, install the information receiving feedback box at the preset position on the outer surface of the airbag module. After the installation is completed, start the information receiving feedback box to test whether the sound and picture received by the host and the display are clear. During the lifting of the steel box girder, the specific position of the obstacle is locked through the information receiving feedback box, and then fed back to the lifting personnel through the display and the host, reducing the risk of collision during the lifting of the steel box girder. When the obstacle is hit due to uncontrollable factors, the airbag module protects the steel box girder from deformation. When a collision occurs, the buffer inflation module performs radial buffering protection on the steel box girder and the airbag module, making the steel box girder and the airbag module less likely to shake. At the same time, the airbag module can be supplemented with air to make the protection effect of the airbag module better, reduce the collision and friction between the airbag module and the obstacle, and extend the service life of the airbag module.

[0008] Furthermore, a plurality of information receiving feedback boxes are provided, and the plurality of information receiving feedback boxes are installed on the airbag module at set distances according to actual needs.

[0009] Setting up multiple information receiving and feedback boxes can detect and alarm obstacles around the steel box girder in all directions without blind spots, thus improving the overall safety of lifting.

[0010] Furthermore, the information receiving feedback box includes a high-precision radar ranging sensor, a high-definition camera, a multi-function warning light and a multi-function alarm, and the high-precision radar ranging sensor, high-definition camera, multi-function warning light and multi-function alarm are all arranged in the information receiving feedback box, and the high-precision radar ranging sensor, high-definition camera, multi-function warning light and multi-function alarm are electrically connected to the decoding converter respectively.

[0011] During the hoisting process, the high-precision radar ranging sensor and high-definition camera in the information receiving feedback box obtain obstacle information and pass it to the decoding converter, which decodes and processes the information and feeds it back to the host. The host performs digital analysis and calculation and then feeds back to the display in the cab. The hoisting personnel can more intuitively understand the position of the obstacle and the hoisting steel box girder, eliminating the visual blind spot of the hoisting personnel. When the hoisting steel box girder is less than 300cm away from the obstacle, the decoding converter feeds back the information to the multi-function warning light, multi-function alarm and display. The multi-function warning light flashes yellow and the multi-function alarm sounds an alarm. The speaker of the host reminds the hoisting personnel and a red obstacle following frame appears on the display. When the hoisting steel box girder is less than 100cm away from the obstacle, the red light of the multi-function warning light is always on and the multi-function alarm sounds a sharp explosion. The speaker of the host sends out a danger alarm and plays it in a loop to remind the driver to be cautious in hoisting operations and stop hoisting operations if necessary.

[0012] Furthermore, each group of the airbag modules includes an outer airbag, a honeycomb anti-collision pad and an inner airbag, the outer airbag is provided with an information receiving feedback box, the honeycomb anti-collision pad is arranged between the outer airbag and the inner airbag, the upper and lower end surfaces of the honeycomb anti-collision pad are respectively abutted against the outer airbag and the inner airbag, the two ends and the middle section of the inner airbag are provided with a buffer inflation module, the inner airbag and the buffer inflation module are fixedly connected, the inner airbag is arranged between the honeycomb anti-collision pad and the buffer inflation module, and some inflation ports of the inner airbag and the air outlet of the buffer inflation module are connected through a hose.

[0013] The information receiving feedback box is set on the outer airbag and will not be blocked from the field of vision, which can provide more fields of vision. When a collision occurs, the outer airbag acts as an initial buffer and the internal honeycomb anti-collision pad acts as a secondary buffer, which greatly reduces the impact force caused by the collision. The inner airbag eliminates the residual force of the honeycomb anti-collision pad's extrusion deformation and protects the steel box girder from deformation.

[0014] Furthermore, the buffer inflation module includes a fixed seat, a connecting piece, a piston rod and a buffer spring, the air outlet of the fixed seat and the inflation port of the inner airbag are connected through a hose, piston cylinders are provided at both ends of the fixed seat, the two piston cylinders are symmetrical about an axial symmetry plane of the fixed seat, the connecting piece is inserted into the fixed seat, the connecting piece and the fixed seat are slidably connected, the top of the connecting piece is fixedly connected to the inner airbag, the two ends of the connecting piece inserted into the fixed seat are respectively fixedly connected to one end of the two piston rods, the piston ends of the two piston rods are respectively inserted into the two piston cylinders, the two piston rods and the two piston cylinders are respectively slidably connected, one end of the buffer spring is fixedly connected to the connecting piece, the other end of the buffer spring is fixedly connected to the piston cylinder, and the buffer spring is sleeved on the piston rod.

[0015] When a collision occurs, the heavier steel box girder will cause relative sliding between the fixed seat and the connecting piece. When relative sliding occurs, the connecting piece pushes the piston rod at one end to move toward the bottom end of the piston cylinder at one end of the fixed seat, and the buffer spring at one end is compressed. The air outlet at one end of the fixed seat inflates the inner airbag through a hose. At the same time, the piston rod at the other end moves away from the bottom end of the piston cylinder at the other end of the fixed seat, the buffer spring at the other end is stretched, and air is taken in at the air inlet at the other end of the fixed seat. The buffer inflation module can only discharge or inhale at the same time.

[0016] Furthermore, a limiting groove is provided at the top of the fixing seat.

[0017] A buffer rubber pad is also provided on the limit groove, which limits the sliding of the connecting part in the fixed seat, so that the connecting part cannot push the piston rod to the bottom end of the piston cylinder and collide with the structure of the two ends of the fixed seat and the piston cylinder, thereby increasing the service life of the buffer inflation module.

[0018] Furthermore, inflation pipes are provided at both ends of the fixing seat, one end of the inflation pipe is connected to the piston cylinder, and the other end of the inflation pipe is connected to the inner air bag through a hose, and an inflation spring and an inflation cover are provided in the inflation pipe, one end of the inflation spring is fixedly connected to a shaft shoulder in the inflation pipe, and the other end of the inflation spring is fixedly connected to the inflation cover, and the inflation cover can completely block the inflation pipe when the inflation spring is not subjected to external force.

[0019] Furthermore, air intake pipes are provided at both ends of the fixed seat, one end of the air intake pipe is connected to the piston cylinder, and limiting columns are provided on both sides of the piston cylinder at the connection point with the air intake pipe, and an air intake cover is provided on the limiting columns. The air intake cover and the limiting columns are slidably connected, and the air intake cover can completely block the air intake pipe. The other end of the air intake pipe is connected to the outside air, the diameter of the air intake pipe is smaller than the diameter of the inflation pipe, and the pipe length of the air intake pipe is greater than the pipe length of the inflation pipe.

[0020] The air discharge and air intake of the buffer inflation module can only be performed at one at the same time. When the buffer inflation module discharges air, the air intake cover blocks the air intake pipe, and when the buffer inflation module inhales air, the air inflation cover blocks the air intake pipe. When a collision occurs, the heavy steel box girder will cause the fixed seat and the connecting piece to slide relative to each other. When relative sliding occurs, the connecting piece pushes the piston rod at one end to move toward the bottom end of the piston cylinder at one end of the fixed seat, and the buffer spring at one end is compressed. The air inflation spring in the air intake pipe at one end of the fixed seat is pressed down by the air inflation cover under the action of pressure, and the air intake pipe is opened. The air intake cover blocks the air intake pipe under the action of pressure, and the inner airbag is inflated under the push of the piston rod at one end. At the same time, the piston rod at the other end moves away from the bottom end of the piston cylinder at the other end of the fixed seat, and the buffer spring at the other end The impact spring is stretched, and the inflation cover in the inflation pipe at the other end of the fixed seat blocks the inflation pipe under the action of pressure and the inflation spring, and the suction cover slides on the limit column under the action of pressure to open the suction pipe, and suction is carried out under the push of the piston rod at one end; since the diameter of the suction pipe is smaller than the diameter of the inflation pipe and the pipe length of the suction pipe is greater than the pipe length of the inflation pipe, it is easier to inflate the buffer inflation module than to inhale, and the difference in inflation and suction speed can buffer the steel box girder, making the steel box girder and the airbag module less likely to shake, and at the same time, the airbag module can be supplemented with air to make the protection effect of the airbag module better, reduce the collision and friction between the airbag module and obstacles, and extend the service life of the airbag module.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. During the hoisting process, the high-precision radar ranging sensor and high-definition camera in the information receiving feedback box obtain obstacle information and transmit it to the decoding converter, which decodes and processes the information and feeds it back to the host. The host performs digital analysis and calculation and then feeds it back to the display in the cab. The hoisting personnel can intuitively understand the relative position of the obstacle and the hoisting steel box girder through the display, effectively eliminating the visual blind spot; at the same time, within the preset safety distance range, different levels of warnings or protection measures can be triggered according to the position of the obstacle to ensure the safety of the hoisting process;

[0023] 2. The airbag module of the present invention includes an outer airbag, a honeycomb anti-collision pad and an inner airbag. The information receiving feedback box is arranged on the outer airbag so that the field of vision is not blocked and more fields of vision can be provided. When a collision occurs, the outer airbag acts as an initial buffer and the inner honeycomb anti-collision pad acts as a secondary buffer, which greatly reduces the impact force caused by the collision. The inner airbag eliminates the residual force of the extrusion deformation of the honeycomb anti-collision pad and protects the steel box girder from deformation.

[0024] 3. The buffering and inflating module of the present invention is easier to inflate than to inhale. The difference in inflation and inhalation speeds can buffer the steel box girder, making the steel box girder and the airbag module less likely to shake. At the same time, the airbag module can also be supplemented with air to make the protection effect of the airbag module better, reduce the collision and friction between the airbag module and obstacles, and extend the service life of the airbag module.

[0033] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present invention.

[0034] Example: Figure 1 - Figure 7 As shown, the present invention provides a technical solution for hoisting equipment with anti-collision function for viaduct steel box girders:

[0035] Working principle of the present invention:

[0036] like Figure 1 to Figure 3 As shown, the hoisting equipment includes an information receiving feedback box 1, a decoding converter 2, a signal receiver 3, a host 4, a display 5, a solar panel 6, a battery 7, an airbag module 8, a buffering and inflating module 9 and a steel box beam 10. The information receiving feedback box 1 is fixedly connected to the outer surface of the airbag module 8, the decoding converter 2 is electrically connected to the information receiving feedback box 1, one of the signal receivers 3 is electrically connected to the decoding converter 2, the positive and negative poles of the battery 7 are electrically connected to the decoding converter 2, the solar panel 6 is electrically connected to the battery 7, the other signal receiver 3 is electrically connected to the host 4, the two signal receivers 3 are connected by signal, the host 4 is electrically connected to the display 5, and the airbag module 8 is electrically connected. There are multiple groups of airbag modules 8, which radially wrap the steel box girder 10. Each group of airbag modules 8 are connected by snap buckles. Both ends and the middle section of each group of airbag modules 8 are provided with buffer inflation modules 9. Part of the inflation port of each group of airbag modules 8 and the air outlet of the buffer inflation module 9 are connected through a hose 919. Each group of airbag modules 8 and the buffer inflation module 9 are fixedly connected. The buffer inflation module 9 and the steel box girder 10 are fixedly connected. The buffer inflation module 9 is arranged at both ends and the middle section of the steel box girder 10. The buffer inflation module 9 is located between the steel box girder 10 and the airbag module 8. Each group of airbag modules 8 and the buffer inflation module 9 are located between the two axial end faces of the steel box girder 10.

[0037] When using the lifting equipment, first connect the airbag module 8 with the buffer inflation module 9, then lift the steel box girder 10 off the ground, connect the buffer inflation module 9 with the steel box girder 10, and after the connection is completed, inflate the airbag module 8 until it meets the airbag use standards, and finally install the information receiving feedback box 1 at a preset position on the outer surface of the airbag module 8. After the installation work is completed, start the information receiving feedback box 1 to test whether the receiving sound and picture of the host 4 and the display 5 are clear. During the lifting process of the steel box girder 10, the specific position of the obstacle is locked through the information receiving feedback box 1. The information is then fed back to the hoisting personnel through the display 5 and the host 4, thereby reducing the risk of collision during the hoisting of the steel box girder 10. When the steel box girder 10 collides with an obstacle due to uncontrollable factors, the airbag module 8 protects the steel box girder 10 from deformation. When a collision occurs, the buffering and inflation module 9 performs radial buffering protection on the steel box girder 10 and the airbag module 8, making it difficult for the steel box girder 10 and the airbag module 8 to shake. At the same time, the airbag module 8 can be supplemented with air to make the protection effect of the airbag module 8 better, reduce the collision and friction between the airbag module 8 and the obstacle, and extend the service life of the airbag module 8.

[0038] like Figure 1 and Figure 2 As shown, a plurality of information receiving feedback boxes 1 are provided, and the plurality of information receiving feedback boxes 1 are installed on the airbag module 8 at set distances according to actual needs.

[0039] A plurality of information receiving and feedback boxes 1 are provided, so that obstacles around the steel box girder 10 can be detected and alarmed in all directions without blind spots, thereby improving the overall safety of the hoisting.

[0040] like Figure 3 As shown, the information receiving feedback box 1 includes a high-precision radar ranging sensor 11, a high-definition camera 12, a multi-function warning light 13 and a multi-function alarm 14, and the high-precision radar ranging sensor 11, the high-definition camera 12, the multi-function warning light 13 and the multi-function alarm 14 are all arranged in the information receiving feedback box 1, and the high-precision radar ranging sensor 11, the high-definition camera 12, the multi-function warning light 13 and the multi-function alarm 14 are electrically connected to the decoding converter 2 respectively.

[0041] During the hoisting process, the high-precision radar ranging sensor 11 and the high-definition camera 12 in the information receiving feedback box 1 obtain obstacle information and transmit it to the decoding converter 2. The decoding converter 2 decodes and processes the information and feeds it back to the host 4. The host 4 performs digital analysis and calculation and then feeds back to the display 5 in the cab. The hoisting personnel can more intuitively understand the position of the obstacle and the hoisting steel box girder 10, eliminating the visual blind spot of the hoisting personnel. When the hoisting steel box girder 10 is less than 300cm away from the obstacle, the decoding converter 2 feeds back the information to the multi-function warning light 13, the multi-function alarm 14 and the display 5. The multi-function warning light 13 flashes yellow and the multi-function alarm 14 sounds an alarm. The speaker of the host 4 reminds the hoisting personnel and a red obstacle following frame appears on the display 5. When the hoisting steel box girder 10 is less than 100cm away from the obstacle, the red light of the multi-function warning light 13 is always on and the multi-function alarm 14 emits a sharp explosion sound. The speaker of the host 4 issues a danger alarm and plays it in a loop to remind the driver to be cautious in the hoisting operation and stop the hoisting operation if necessary.

[0042] like Figure 4 As shown, each group of the airbag modules 8 includes an outer airbag 81, a honeycomb anti-collision pad 82 and an inner airbag 83, the outer airbag 81 is provided with an information receiving feedback box 1, the honeycomb anti-collision pad 82 is arranged between the outer airbag 81 and the inner airbag 83, the upper and lower end surfaces of the honeycomb anti-collision pad 82 are respectively abutted against the outer airbag 81 and the inner airbag 83, the two ends and the middle section of the inner airbag 83 are provided with a buffering and inflation module 9, the inner airbag 83 and the buffering and inflation module 9 are fixedly connected, the inner airbag 83 is arranged between the honeycomb anti-collision pad 82 and the buffering and inflation module 9, and part of the inflation port of the inner airbag 83 and the air outlet of the buffering and inflation module 9 are connected through a hose 919.

[0043] The information receiving feedback box 1 is arranged on the outer airbag 81 so that the field of vision will not be blocked and more fields of vision can be provided. When a collision occurs, the outer airbag 81 performs initial buffering and the internal honeycomb anti-collision pad 82 performs secondary buffering, which greatly reduces the impact force caused by the collision. The inner airbag 83 eliminates the residual force of the extrusion deformation of the honeycomb anti-collision pad 82 and protects the steel box girder 10 from deformation.

[0044] like Figure 5 and Figure 6As shown, the buffer inflation module 9 includes a fixed seat 91, a connecting member 92, a piston rod 93 and a buffer spring 94. The air outlet of the fixed seat 91 and the inflation port of the inner air bag 83 are connected through a hose 919. Piston cylinders 911 are provided at both ends of the fixed seat 91. The two piston cylinders 911 are symmetrical about an axial symmetry plane of the fixed seat 91. The connecting member 92 is inserted into the fixed seat 91, and the connecting member 92 and the fixed seat 91 are slidably connected. The top of the connecting member 92 is fixedly connected to the inner air bag 83, and the two ends of the connecting member 92 inserted into the fixed seat 91 are respectively fixedly connected to one end of the two piston rods 93, and the piston ends of the two piston rods 93 are respectively inserted into the two piston cylinders 911, and the two piston rods 93 and the two piston cylinders 911 are respectively slidably connected. One end of the buffer spring 94 is fixedly connected to the connecting member 92, and the other end of the buffer spring 94 is fixedly connected to the piston cylinder 911, and the buffer spring 94 is sleeved on the piston rod 93.

[0045] When a collision occurs, the heavier steel box girder 10 will cause the fixed seat 91 and the connecting piece 92 to slide relative to each other. When relative sliding occurs, the connecting piece 92 pushes the piston rod 93 at one end to move toward the bottom end of the piston cylinder 911 at one end of the fixed seat 91, and the buffer spring 94 at one end is compressed. The air outlet at one end of the fixed seat 91 inflates the inner airbag 83 through the hose 919; at the same time, the piston rod 93 at the other end moves away from the bottom end of the piston cylinder 911 at the other end of the fixed seat 91, and the buffer spring 94 at the other end is stretched, and the air inlet at the other end of the fixed seat 91 is inducted; the buffer inflation module 9 can only perform one of the air outlet and air intake at the same time.

[0046] like Figure 5 As shown, a limiting groove 918 is provided at the top of the fixing seat 91 .

[0047] A buffer rubber pad is also provided on the limiting groove 918, which limits the sliding of the connecting member 92 in the fixing seat 91, so that the connecting member 92 cannot push the piston rod 93 to the bottom end of the piston cylinder 911, thereby colliding with the structures of the two ends of the fixing seat 91 and the piston cylinder 911, thereby increasing the service life of the buffer inflation module 9.

[0048] like Figure 7 As shown, an inflation pipe 912 is provided at both ends of the fixed seat 91, one end of the inflation pipe 912 is connected to the piston cylinder 911, and the other end of the inflation pipe 912 is connected to the inner air bag 83 through a hose 919, and an inflation spring 913 and an inflation cover 914 are provided in the inflation pipe 912, one end of the inflation spring 913 is fixedly connected to the shaft shoulder in the inflation pipe 912, and the other end of the inflation spring 913 is fixedly connected to the inflation cover 914, and the inflation cover 914 can completely block the inflation pipe 912 when the inflation spring 913 is not subjected to external force.

[0049] like Figure 7 As shown, both ends of the fixed seat 91 are provided with an air intake pipe 915, one end of the air intake pipe 915 is connected to the piston cylinder 911, and limiting columns 916 are provided on both sides of the piston cylinder 911 at the connection with the air intake pipe 915, and an air intake cover 917 is provided on the limiting column 916. The air intake cover 917 and the limiting column 916 are slidably connected, and the air intake cover 917 can completely block the air intake pipe 915, and the other end of the air intake pipe 915 is connected to the outside air, the diameter of the air intake pipe 915 is smaller than the diameter of the inflation pipe 912, and the pipe length of the air intake pipe 915 is greater than the pipe length of the inflation pipe 912.

[0050] The buffering and inflating module 9 can only perform one of the air outlet and air intake at the same time. When the buffering and inflating module 9 is exhausting, the air intake cover 917 blocks the air intake pipe 915, and when the buffering and inflating module 9 is inhaling, the inflation cover 914 blocks the inflation pipe 912; when a collision occurs, the heavy steel box girder 10 will drive the fixed seat 91 and the connecting piece 92 to slide relative to each other. When relative sliding occurs, the connecting piece 92 pushes the piston rod 93 at one end to move toward the bottom end of the piston cylinder 911 at one end of the fixed seat 91, and the buffer spring 94 at one end is compressed. The inflation spring 913 in the inflation pipe 912 at one end of the fixed seat 91 is pressed down by the inflation cover 914 under the action of pressure, and the inflation pipe 912 is opened. The air intake cover 917 blocks the air intake pipe 915 under the action of pressure, and the inner airbag 83 is inflated under the push of the piston rod 93 at one end; at the same time, the piston rod 93 at the other end is away from the piston cylinder 911 at the other end of the fixed seat 91. At the bottom end, the buffer spring 94 at the other end is stretched, and the inflation cover 914 in the inflation pipe 912 at the other end of the fixed seat 91 blocks the inflation pipe 912 under the action of pressure and the inflation spring 913, and the suction cover 917 slides on the limit column 916 under the action of pressure, opens the suction pipe 915, and inhales air under the push of the piston rod 93 at one end; since the diameter of the suction pipe 915 is smaller than the diameter of the inflation pipe 912, the pipeline length of the suction pipe 915 is greater than the pipeline length of the inflation pipe 912, it is easier for the buffer inflation module 9 to inflate than to inhale, and the difference in inflation and suction speed can buffer the steel box girder 10, making the steel box girder 10 and the airbag module 8 less likely to shake, and at the same time, the airbag module 8 can be supplemented with air to make the protection effect of the airbag module 8 better, and reduce the collision and friction between the airbag module 8 and obstacles, thereby extending the service life of the airbag module 8.

[0051] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
