Description

Technical Field

[0001] The invention relates to the technical field of subway construction, in particular to a suspension bracket used for constructing a rail top air duct at a station. Background Art

[0002] In the structure of subway stations, the track-top air duct is responsible for the exhaust and air supply of the subway and is an important part of the subway station structure. The track-top air duct is located above the track area of ​​the station, and its cross-section is approximately rectangular and is hung below the main structure middle plate. Under normal circumstances, there are two methods for post-casting the track-top air duct construction: ① When constructing the middle plate of the main structure of the subway station, reserve the side wall hanging bars of the track-top air duct, then seal the mold, and cast the side walls and bottom plate of the track-top air duct; ② Use the method of embedding reinforcement to accurately plant the side wall hanging bars at the bottom of the main structure middle plate, then seal the mold, and cast the side walls and bottom plate of the track-top air duct; When casting the track-top air duct, the methods used to construct the track-top air duct include the full-chamber bracket method, the trolley method, etc.

[0003] The existing suspension bracket for the construction of the track top air duct at the station needs to find the center of the track top air duct when the trolley moves to the lower side of the track top air duct and supports the pouring of the track top air duct, so as to support the track top air duct with the supporting part of the trolley, otherwise it will affect the working efficiency and construction quality of the pouring of the track top air duct. At present, due to the narrow construction area of ​​the track top air duct, it is inconvenient to find the center position, resulting in poor supporting effect and very inconvenient use. Therefore, in view of the above situation, it is urgent to develop a suspension bracket for the construction of the track top air duct at the station to overcome the shortcomings in current practical applications. Summary of the invention

[0004] The object of the present invention is to provide a suspension bracket for constructing a rail top air duct at a station, so as to solve the problems raised in the above-mentioned background technology.

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

[0009] A centering mechanism, wherein the centering mechanism is connected to the moving frame and the supporting frame respectively;

[0010] Among them, the center alignment mechanism includes a driving component, a sliding component and a detection component, the detection component includes a moving unit, a positioning detection frame, a moving pressure block, a detection spring, a slide rail B and a warning detection unit, the moving unit is connected to the support frame, and the positioning detection frame is installed on the mobile unit.

Then, the set mobile unit is started to drive the detection frame to move upward and be located on both sides of the rail-top air duct body. At this time, the rail-top air duct body has not been poured yet, and is a structure tied with steel bars. When the mobile pressure block on the detection frame is in the rail-top air duct After the moving pressure block is positioned at both ends of the detection frame, the detection spring is in a stretched state, and there are two sets of detection springs, which are respectively located on both sides of the warning detection unit. In the process of the moving pressure block continuously moving toward the middle of the detection frame, it can contact the side wall of the rail top air duct body. At this time, the two sets of moving pressure blocks are in a stationary state, and if the casting support assembly on the support frame is not located directly under the detection spring When the support frame is close to the left side of the track top air duct body, a buzzer sound is emitted, and when the support frame is close to the right side of the track top air duct body, the colored flashing light starts to flash to remind the staff. At this time, by starting the driving component, the sliding component can be driven to work, and the support frame can move horizontally on the moving frame and the sliding component, and the detection springs on both sides of the warning detection unit can be gradually balanced. When the casting support component on the support frame is located directly below the track top air duct body, the difference in deformation between the detection springs on both sides is very small and can be within the error range, and the tension of the detection spring is approximately zero at this time, so that the buzzer sound or colored flashing light can be stopped, so as to remind the staff that the casting support component is just below the track top air duct body at this time. The operation is simple and the cost is low. It is conducive to quickly finding the center position of the track top air duct body, so as to achieve a better support effect in the subsequent casting work, and can improve the casting work efficiency and construction quality, which is worthy of promotion.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0021] See also Figure 1-5 The embodiment of the present invention provides a suspension bracket for constructing a rail top air duct of a station, comprising a mobile frame 1, on which a load-bearing support leg 2 is provided, and further comprising:

[0022] A support frame 12, wherein the support frame 12 is slidably connected to the mobile frame 1;

[0023] A support mechanism, the support mechanism is located on the support frame 12, wherein the support mechanism includes a casting support assembly and a rail top air duct body 16, the casting support assembly is connected to the support frame 12, and the rail top air duct body 16 is detachably connected to the casting support assembly; and

[0024] A centering mechanism, wherein the centering mechanism is connected to the mobile frame 1 and the support frame 12 respectively;

[0025] Among them, the center alignment mechanism includes a driving component, a sliding component and a detection component, and the detection component includes a moving unit, a positioning detection frame 8, a moving pressure block 31, a detection spring 36, a slide rail B37 and a warning detection unit. The moving unit is connected to the support frame 12, and the positioning detection frame 8 is installed on the mobile unit. The positioning detection frame 8 is provided with a moving pressure block 31 and a warning detection unit. The moving pressure block 31 is slidingly connected to the positioning detection frame 8 through the slide rail B37, and the moving pressure block 31 is detachably connected to the rail top air duct body 16, and the two ends of the detection spring 36 are respectively connected to the moving pressure block 31 and the warning detection unit.

[0026] During the construction of the rail-top air duct body 16, first, a mobile frame 1 is set up, wherein the bottom of the mobile frame 1 is provided with wheels, which can be moved on the laid track to the bottom of the rail-top air duct body 16, and the load-bearing legs 2 are set up, so that the wheels on the mobile frame 1 can be in a braking state to prevent the equipment from moving during the subsequent pouring process. Then, the set mobile unit is started, which can drive the detection frame 8 to move upward and be located on both sides of the rail-top air duct body 16. At this time, the rail-top air duct body 16 has not been poured yet, and is a structure tied with steel bars. When the mobile pressing block 31 on the detection frame 8 is located on the rail-top air duct body 16, the movable pressing block 31 can be released, and under the pull of the detection spring 36, the movable pressing block 31 can slide smoothly toward the middle of the detection frame 8 through the slide rail B37, wherein, when the movable pressing block 31 is located at both ends of the detection frame 8, the detection spring 36 is in a stretched state, and the number of the detection spring 36 is two sets, which are respectively located on both sides of the warning detection unit. In the process of the movable pressing block 31 continuously moving toward the middle of the detection frame 8, it can contact the side wall of the rail top air duct body 16. At this time, the two sets of movable pressing blocks 31 are in a stationary state, and if the casting support assembly on the support frame 12 is not located When the detection spring 36 is directly below the warning detection unit, the deformation of the detection springs 36 on both sides of the warning detection unit is different. At this time, the warning detection unit will work, and a buzzer sound and a color flashing light can be emitted. When the support frame 12 is close to the left side of the rail top air duct body 16, a buzzer sound is emitted. When the support frame 12 is close to the right side of the rail top air duct body 16, the color flashing light starts to flash to remind the staff. At this time, by starting the driving component, the sliding component can be driven to work, and the support frame 12 can be moved horizontally on the moving frame 1 and the sliding component, and the detection springs 36 on both sides of the warning detection unit can be gradually balanced. When the pouring support assembly on the support frame 12 is located directly below the rail top air duct body 16, the difference in deformation between the detection springs 36 on both sides is very small and within the error range, and the tension of the detection spring 36 is approximately zero at this time, so that the buzzing sound or the colored flashing light can be stopped, thereby reminding the staff that the pouring support assembly is just located directly below the rail top air duct body 16 at this time. The operation is simple and the cost is low, which is conducive to quickly finding the center position of the rail top air duct body 16, so as to achieve a better support effect in the subsequent pouring work, and can improve the pouring work efficiency and construction quality, which is worthy of promotion.

[0028] A lifting member 6, wherein the lifting member 6 is connected to the support frame 12;

[0029] a telescopic member 7, wherein the telescopic member 7 is slidably connected to the lifting member 6, and the telescopic member 7 is connected to the alignment detection frame 8; and

[0030] The connecting rod 5 is located between the two sets of lifting members 6.

[0031] See also Figure 1 and Figure 5 , the warning detection unit comprises:

[0032] A detection warning box 38, the detection warning box 38 is located in the middle of the slide rail B37, a placement cavity 44 is provided in the detection warning box 38, and a partition plate 43 is installed in the middle of the inner wall of the placement cavity 44;

[0033] A tension spring 42, one end of which is connected to the partition plate 43;

[0034] A detection slide post 39, one side of which is connected to the other end of the tension spring 42, the other side of which passes through the detection warning box 38 and is connected to the detection spring 36, and the detection slide post 39 is also slidably connected to the placement cavity 44 through a sliding guide 41; and

[0035] A transfer module, wherein the transfer module is connected to the detection slide post 39 and the slide rail B37 respectively.

[0036] The transmission module includes: a sensor 40, the sensor 40 is located on the end of the detection slide 39 and is detachably connected to the inner wall of the placement cavity 44; and

[0037] The warning member 9 is connected to the outer side wall of the alignment detection frame 8 , and the warning member 9 is also electrically connected to the sensor 40 .

[0038] See also Figure 4 and Figure 5 , further comprising: a magnetic attraction member A32, the magnetic attraction member A32 being located on the side wall of the alignment detection frame 8 and being detachably connected to the movable pressing block 31;

[0039] a resistance plate 33, wherein the resistance plate 33 is slidably connected to the inner wall of the alignment detection frame 8 via a slide rail A34, and the resistance plate 33 is also detachably connected to the movable pressing block 31; and

[0040] The magnetic attraction component B35 is located on the inner wall of the alignment detection frame 8 and is installed in coordination with the resistance plate 33 .

[0041] By means of the provided lifting member 6 and telescopic member 7, both of which can be in the form of electric push rods or cylinders, the detection frame 8 can be lifted to a certain height in the longitudinal direction until the moving pressing block 31 is located at both ends of the rail top air duct body 16, and the detection frame 8 is pushed in the horizontal direction toward the rail top air duct body 16 until the moving pressing block 31 can contact the rail top air duct body 16 after sliding. At this time, the magnetic suction member A32 can be disengaged from the moving pressing block 31, and under the thrust of the magnetic suction member B35, the resistance plate 33 can slide on the slide rail A34 and contact the side wall of the moving pressing block 31, wherein the magnetic suction member B35 can be used to prevent the resistance plate 33 from sliding on the slide rail A34 and contact the side wall of the moving pressing block 31. Both the suction piece A32 and the magnetic suction piece B35 can be in the form of an electromagnet. When not in use, the movable pressure block 31 can be fixed on both ends of the detection frame 8, and during the sliding process of the movable pressure block 31, the magnetic repulsion between the magnetic suction piece B35 and the resistance plate 33 can increase the friction between the resistance plate 33 and the movable pressure block 31, thereby playing a damping role, preventing the movable pressure block 31 from colliding with the side wall of the rail top air duct body 16 under the pulling force of the detection spring 36, and after the movable pressure block 31 contacts the rail top air duct body 16, the direction of the current passed into the magnetic suction piece B35 can be reversed, and under the action of the magnetic suction force, the resistance plate 33 is separated from the moving pressing block 31 to avoid affecting subsequent work. When the moving pressing block 31 contacts the rail top air duct body 16 and the deformation amounts of the two sets of detection springs 36 are different, the detection slide column 39 will slide in the placement cavity 44 through the sliding guide 41 under the pulling force of the detection spring 36, wherein the sliding guide 41 can adopt the structure of a guide rail and a slider. When the detection slide column 39 drives the sensor 40 to be close to the side wall of the placement cavity 44, the warning member 9 will be started to work, wherein the warning member 9 can adopt the structure of a buzzer and a colored flashing light, and the tension spring 42 connected to the detection slide column 39 is in a stretched state, and the tension spring 42 is in a stretched state. The elastic coefficient of the spring 42 is smaller than that of the detection spring 36. At this time, one set of sensors 40 is in contact with the inner wall of the placement cavity 44, and the other set of sensors 40 is not in contact with the inner wall of the placement cavity 44. Then, through the cooperation of the driving component and the sliding component, the detection spring 36 in the stretched state can gradually restore to the relaxed state, and the other set of detection springs 36 in the compressed state can also gradually restore to the relaxed state. When the elastic forces of the detection springs 36 on both sides are approximately equal and approximately equal to zero, under the pull of the two sets of tension springs 42, the two sets of sensors 40 can be separated from the inner wall of the placement cavity 44, thereby achieving the purpose of finding the center.

[0042] In one embodiment of the present invention, see Figure 1-3 , the driving assembly comprises:

[0043] A centering adjustment box 3, the centering adjustment box 3 is connected to the mobile frame 1, and a supporting partition 23 is fixedly installed in the centering adjustment box 3;

[0045] A rotating shaft 28, the rotating shaft 28 is connected to the output end of the regulating motor 30 and is rotatably connected to the supporting partition 23;

[0046] a rotating wheel 24 connected to the rotating shaft 28; and

[0047] A swing unit is connected to the supporting baffle 23 and the rotating wheel 24 respectively.

[0048] The swing unit includes: a slider A22, the slider A22 is rotatably connected to the supporting partition 23;

[0049] A swing adjustment frame 19, one end of which is slidably connected to the slider A22 via a sliding groove 20, and the sliding groove 20 is provided on the swing adjustment frame 19; and

[0050] The slider B25 is slidably installed in the sliding groove 20 and is rotatably connected to the rotating wheel 24.

[0051] See also Figure 1-3 , the sliding assembly comprises:

[0052] A guide plate 10, wherein the guide plate 10 is connected to the centering adjustment box 3, and a swing notch 26 is provided at the bottom of the guide plate 10, and the swing notch 26 is connected to the swing adjustment frame 19 through and through;

[0055] The damping strips 27 are respectively located on the inner side walls of the guide plate 10 and the sliding adjustment plate 11 .

[0056] In the process of finding the center, a manipulator 4 is provided on the centering adjustment box 3, which can be used to control all equipment. By starting the adjustment motor 30, the rotating shaft 28 and the rotating wheel 24 can be driven to rotate, and the slider B25 can be driven to slide in the sliding groove 20. When the slider B25 is clamped and slid with the sliding groove 20, the slider A22 can also be in two states of rotation and sliding, so that the swing adjustment frame 19 swings. At this time, the sliding adjustment plate 11 can be driven to slide left or right in the guide plate 10. When the sliding adjustment plate 11 slides, the two sets of damping strips 27 are in contact and friction with each other, which can play a damping role. When the sliding adjustment plate 11 slides, it can drive the support frame 12 to move synchronously, so as to achieve the purpose of driving the casting support assembly to quickly find the center of the rail top air duct body 16.

[0057] In one embodiment of the present invention, please refer to Figure 2 and Figure 3 , and also includes: a swing position detection member 21, both ends of which are connected to the centering adjustment box 3 and the swing adjustment frame 19 respectively.

Of course, a simpler spring dynamometer can also be used, as long as it can measure the tension value on both sides of the swing adjustment frame 19 when it swings, and the specific structure of the swing position detection member 21 is not discussed here. The body structure is limited, and during the swinging process of the swing adjustment frame 19, its movement state is that when the swing adjustment frame 19 is in a vertical state, the bottom end of the swing adjustment frame 19 is closest to the inner bottom wall of the centering adjustment box 3, and when the swing adjustment frame 19 is swung to the far right or far left, the bottom end of the swing adjustment frame 19 is farthest from the inner bottom of the centering adjustment box 3. Therefore, the swing angle of the swing adjustment frame 19 when the casting support assembly is located directly below the rail top air duct body 16 can be known through the display of the tension value of the swing orientation detection parts 21 located on both sides of the swing adjustment frame 19, so that in subsequent batch work, the support frame 12 can be directly positioned here to improve work efficiency, and when the tension value is zero, the swing adjustment frame 19 is just in a vertical state.

[0059] In one embodiment of the present invention, please refer to Figure 1 , the pouring support assembly comprises:

[0062] A push rod 15 is detachably connected to the support frame 12 and the L-shaped support plate 14 respectively.

[0063] When not in operation, the L-shaped support plate 14 and the pouring baffle 18 are in an inclined state to lower the height of the entire equipment and facilitate the movement of the entire equipment. When moved to the bottom of the rail-top air duct body 16, a number of supporting cylinders A13 and supporting cylinders B17 can be used to make the L-shaped support plate 14 and the pouring baffle 18 contact the side walls of the rail-top air duct body 16 respectively to achieve the purpose of support. When not in operation, the top rod 15 can be removed from between the support frame 12 and the L-shaped support plate 14 to facilitate the rotation of the L-shaped support plate 14. When in operation, the supporting effect of the L-shaped support plate 14 can be further improved through the supporting function of the top rod 15.

[0064] In summary, during the construction of the rail-top duct body 16, first, a mobile frame 1 is provided, wherein the bottom of the mobile frame 1 is provided with wheels, which can be moved on the laid track to the bottom of the rail-top duct body 16, and the load-bearing legs 2 are provided, so that the wheels on the mobile frame 1 can be in a braking state to prevent the equipment from moving during the subsequent pouring process. Then, the mobile unit is started, which can drive the detection frame 8 to move upward and be located on both sides of the rail-top duct body 16. At this time, the rail-top duct body 16 has not been poured yet and is a structure tied with steel bars. When the mobile pressing block 31 on the detection frame 8 is on the track, the detection frame 8 can be moved upward and located on both sides of the rail-top duct body 16. After the moving pressure block 31 is moved to the two sides of the top air duct body 16, the moving pressure block 31 can be released, and under the pull of the detection spring 36, the moving pressure block 31 can slide smoothly toward the middle of the detection frame 8 through the slide rail B37, wherein, when the moving pressure block 31 is located at the two ends of the detection frame 8, the detection spring 36 is in a stretched state, and the number of the detection spring 36 is two sets, which are respectively located on both sides of the warning detection unit, and in the process of the moving pressure block 31 continuously moving toward the middle of the detection frame 8, it can contact the side wall of the rail top air duct body 16, at this time, the two sets of moving pressure blocks 31 are in a stationary state, and if the casting support group on the support frame 12 When the component is not located directly below the detection spring 36, the deformation of the detection springs 36 on both sides of the warning detection unit is different. At this time, the warning detection unit will work, and a buzzer sound and a color flashing light can be emitted. When the support frame 12 is close to the left side of the rail top air duct body 16, a buzzer sound is emitted. When the support frame 12 is close to the right side of the rail top air duct body 16, the color flashing light starts to flash to remind the staff. At this time, by starting the driving component, the sliding component can be driven to work, and the support frame 12 can be moved horizontally on the moving frame 1 and the sliding component, and the detection springs 36 on both sides of the warning detection unit can be gradually Gradually approaching balance, when the casting support assembly on the support frame 12 is located directly below the rail top air duct body 16, the deformation difference between the detection springs 36 on both sides is very small and within the error range, and at this time the tension of the detection spring 36 is approximately zero, so that the buzzing sound or colored flashing light can be stopped, thereby reminding the staff that the casting support assembly is just located directly below the rail top air duct body 16 at this time. The operation is simple and the cost is low, which is conducive to quickly finding the center position of the rail top air duct body 16, so as to achieve a better support effect in the subsequent casting work, and can improve the casting work efficiency and construction quality.
