[0001] The invention relates to the technical field of cast-in-place pipe gallery, in particular to a single-sided support formwork for a cast-in-place pipe gallery. Background Art

[0002] Pipeline corridors, or underground pipeline integrated corridors, are structures and ancillary facilities built underground in cities to accommodate two or more types of urban engineering pipelines. Cast-in-place pipeline corridors refer to the formation of pipeline corridor structures by directly pouring concrete at the construction site. Different from prefabricated pipeline corridors (pipeline corridor components are prefabricated in the factory and then transported to the site for assembly), when constructing cast-in-place pipeline corridors, for some parts of the pipeline corridor, only the formwork needs to be set up and supported on one side of the concrete pouring, which is a single-sided support formwork.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The single-sided support formwork of the cast-in-place pipe gallery drives the first gear pulley to rotate through the output shaft of the servo motor. When rotating, the second gear pulley, the cross bar and another gear are driven by the first belt to rotate together. Since the two gears are meshed with the two racks, the second support plates at the top and bottom are driven by the racks when the output shaft of the servo motor rotates forward and reversely. The second support plates are slid out of the square slots in the moving grooves through the corresponding moving blocks, which can facilitate the operator to move the second support plate out of the first support plate according to the length of the cast-in-place pipe gallery to be supported and increase it to a suitable support length, so that the operator can perform single-sided support work on cast-in-place pipe galleries of different lengths and avoid inconvenience to the operator.

[0017] 2. The single-sided support formwork of the cast-in-place pipe gallery rotates the third pulley and the worm through the first belt. The worm is meshed with the worm wheel, which in turn rotates the worm wheel, the fourth pulley and the corresponding reciprocating screw. The rotation of the fourth pulley drives the fifth pulley and another reciprocating screw through the second belt. When the two reciprocating screws rotate, the two fixed plates are driven to slide up and down in the slide groove through the two screw holes through the slider. When sliding, the first support plate is driven to move together, which is convenient for the operator to adjust the height simultaneously when adjusting the length of the extendable support assembly. Therefore, the device can facilitate the support work according to the height adjustment of the cast-in-place pipe gallery with single-sided support required, so that the device has a variety of use effects.

[0018] 3. The single-sided support formwork of the cast-in-place pipe gallery is realized by rotating the square frame to the left or right through the axis rod in the U-shaped frame, so that the extendable support assembly is rotated together to the angle against the cast-in-place pipe gallery, and then the U-shaped seat is slid in the mounting groove through the mounting block to drive the support rod to a suitable position. After moving to the suitable position, the bottoms of the two support rods are rotated through the rotating rod until they can enter and support two suitable slots in multiple slots for support. At the same time, the support rods can be moved out of the slots to release the fixation, and the lifting assembly and the extendable support assembly are turned right to the U-shaped frame for collection, which is convenient for the operator to adjust the two support rods up and down according to the angle of the single-sided support required for the cast-in-place pipe gallery, and to support and collect the lifting assembly and the extendable support assembly, thereby preventing the situation where the normal use work cannot be hindered when the angle of the single-sided support of the cast-in-place pipe needs to be adjusted.

The second pulley 13 and the third pulley 14, the output shaft of the servo motor 9 and the left side of the cross bar 10 are fixedly connected with a gear 16, and the second support plate 6 is slidably connected to the first support plate 1 in the moving groove 3 through the moving block 5. The first support plate 1 and the second support plate 6 are both made of high-strength alloy steel. By setting up an extendable support component, the operator can easily move the second support plate 6 out of the first support plate 1 to increase it to a suitable support length according to the length of the cast-in-place pipeline corridor to be supported, thereby facilitating the operator to perform single-sided support work on cast-in-place pipeline corridors of different lengths, thereby preventing inconvenience to the operator.

[0031] Furthermore, the outer ring movable sleeves of the first pulley 12, the second pulley 13 and the third pulley 14 are provided with a first belt 15, and the gear 16 and the rack 7 are meshed and connected. Through the setting of the first belt 15, when the first pulley 12 rotates, the second pulley 13 and the third pulley 14 can be driven to rotate synchronously. By meshing the gear 16 with the rack 7, the second support plate 6 can be driven to slide through the moving block 5, which can reduce the energy consumption of the device.

[0032] Furthermore, the lifting assembly includes a square frame 17, and both sides of the inner wall of the square frame 17 are provided with slide grooves 18. The inner cavity of the square frame 17 is rotatably connected to two reciprocating screws 19 through bearings. The top of the left reciprocating screw 19 passes through the top of the square frame 17 and is fixedly connected to a worm wheel 20. The middle parts of the two reciprocating screws 19 are respectively covered with a fourth pulley 21 and a fifth pulley 22. The outer rings of the fourth pulley 21 and the fifth pulley 22 are movably covered with a second belt 23. Two mounting grooves 24 are provided on the right side of the square frame 17. The middle parts of the two reciprocating screws 19 are covered with a fixing plate 25. The top of the fixing plate 25 passes through two screw holes 35 that are compatible with the reciprocating screws 19. Both sides of the fixed plate 25 are fixedly connected with sliders 26 that are compatible with the slide groove 18. The extendable support assembly and the lifting assembly are fixedly connected to the first support plate 1 through the square frame 17. The fixed plate 25 is sleeved on the middle part of the two reciprocating screws 19 through the screw hole 35 and is slidably connected to the square frame 17 in the slide groove 18 through the slider 26. The worm wheel 20 is meshed and connected with the worm 11. Through the set lifting assembly, it is convenient for the operator to adjust the height simultaneously when adjusting the length of the extendable support assembly, so that the device can facilitate the support work according to the height adjustment of the cast-in-place pipe gallery with single-sided support required, so that the device has a variety of usage effects.

[0033] Furthermore, the movable connection component includes two mounting blocks 27 slidably connected to the inner cavities of the two mounting grooves 24, and a U-shaped seat 28 is fixedly connected to the right side of the two mounting blocks 27. The inner cavity of the U-shaped seat 28 is rotatably connected to a rotating rod 37 through a bearing, and two support rods 29 are mounted in the middle of the rotating rod 37. The U-shaped seat 28 is slidably connected to the square frame 17 in the mounting groove 24 through the mounting blocks 27. By setting up the movable connection component, it is convenient for the operator to adjust the angle of the two support rods 29 up and down according to the angle of the single-sided support required for the cast-in-place pipeline corridor, so as to support the lifting component and the extendable support component, thereby preventing the situation where the normal use work cannot be hindered when the adjustment is required according to the angle of the single-sided support of the cast-in-place pipeline.

[0034] Furthermore, the fixing assembly includes a U-shaped frame 30 rotatably connected to the bottom of the square frame 17 through an axial rod, and the tops of the two vertical ends of the U-shaped frame 30 are penetrated by a plurality of threaded holes 31, the inner cavities of the plurality of threaded holes 31 are threadedly connected with threaded plug rods 32, the tops of the threaded plug rods 32 are fixedly connected with handles 33, the tops of the handles 33 are fixedly connected with hand guards 34, and the tops of the lateral ends of the U-shaped frame 30 are equidistantly provided with a plurality of slots 36. By setting up the fixing assembly, the operator can conveniently fix the device quickly and tightly to perform single-sided support of the cast-in-place pipe gallery, thereby preventing the device from shaking and affecting the pouring when supporting the cast-in-place pipe gallery.

[0035] Furthermore, the hand ring 34 is made of rubber material, and the bottom of the threaded rod 32 is in a pointed cone shape. The hand ring 34 made of rubber material can protect the operator when he holds the handle 33 to rotate the threaded rod 32, preventing hard contact with the operator's hand to cause wear. At the same time, the bottom of the threaded rod 32 is in a pointed cone shape, which can quickly enter the ground soil supported by the cast-in-place pipeline corridor, preventing the difficulty in entering and fixing when encountering harder soil.

[0036] Working principle: first, place the device at the cast-in-place pipe gallery to be supported, then hold the handle 33 and rotate it to drive the threaded rod 32 to rotate and move down in the threaded hole 31 into the soil. The hand ring 34 made of rubber material can protect the threaded rod 32 when the operator holds the handle 33 to rotate, preventing hard contact with the operator's hand and causing wear. At the same time, the bottom of the threaded rod 32 is set in a pointed cone shape, which can quickly enter the ground soil supported by the cast-in-place pipe gallery to prevent the situation where it is difficult to enter and fix when encountering harder soil. After the fixation is completed, the output shaft of the servo motor 9 drives the first pulley 12 of the gear 16 to rotate, and when rotating, it drives the second pulley 13 and The cross bar 10 rotates together with another gear 16. Since the two gears 16 are meshed with the two racks 7, the second support plates 6 at the top and bottom are driven through the racks 7 when the output shaft of the servo motor 9 rotates forward and reversely through the corresponding moving blocks 5 to slide out in the square slots 2 in the moving grooves 3, which can facilitate the operator to move the second support plate 6 out of the first support plate 1 to increase it to a suitable support length according to the length of the cast-in-place pipe gallery to be supported, so as to facilitate the operator to perform single-sided support work on cast-in-place pipe galleries of different lengths, thereby preventing inconvenience to the operator. The third pulley 14 and the worm 11 are rotated by the first belt 15. Since the worm 11 is meshed with the worm wheel 20, the worm wheel 20 and The fourth pulley 21 and the corresponding reciprocating screw 19 rotate, and the rotation of the fourth pulley 21 drives the fifth pulley 22 and another reciprocating screw 19 to rotate through the second belt 23. When the two reciprocating screws 19 rotate, the two fixed plates 25 are driven to slide up and down in the slide groove 18 through the two screw holes 35 through the slider 26, and the first support plate 1 is driven to move together when sliding, which can facilitate the operator to adjust the height simultaneously when adjusting the length of the extendable support component. Therefore, the device can facilitate the support work according to the height adjustment of the cast-in-place pipe gallery supported on one side, so that the device has a variety of use effects. After the length and height adjustment are completed, the square frame 17 is rotated left or right through the shaft in the U-shaped frame 30 to make it The extendable support assembly rotates together to an angle that is against the cast-in-place pipe gallery, and then the U-shaped seat 28 slides in the mounting groove 24 through the mounting block 27 to drive the support rod 29 to move to a suitable position. After moving to a suitable position, the bottoms of the two support rods 29 are rotated through the rotating rod 37 until they can enter the multiple card slots 36 and support the two suitable card slots 36. At the same time, the support rod 29 can be moved out of the card slot 36 to release the fixation, and the lifting assembly and the extendable support assembly are turned right to the U-shaped frame 30 for collection, which can facilitate the operator to adjust the angle of the two support rods 29 by rotating them up and down according to the angle of the single-sided support required by the cast-in-place pipe gallery, and to carry out the work of resisting, supporting and collecting the lifting assembly and the extendable support assembly.This can prevent the situation where the angle of the single-sided support of the cast-in-place pipe cannot be adjusted, which will hinder normal use.
