Description

Technical Field

[0001] The invention relates to the technical field of foundation pit construction support, and in particular to a support structure that automatically regulates axial force as temperature changes. Background Art

[0002] With the development of the national economy and the acceleration of urbanization, a large number of high-rise and super-high-rise buildings have appeared in cities. In addition, the construction of large-scale municipal facilities and the development and utilization of a large amount of underground space have promoted the development and progress of foundation pit engineering. Since the foundation pit support structure is generally a temporary structure, the temperature effect is often ignored. With the continuous increase in the plane size and depth of the foundation pit, the working time of the support has become longer and longer, and many cross-season construction projects have emerged. The change of seasons and day and night will inevitably bring about the influence of temperature. In some engineering practices and research and analysis by relevant scholars, it is found that the influence of temperature changes on the axial force of the foundation pit cannot be ignored.

[0003] During the use of the foundation pit support structure in the prior art, the axial force control devices located at both ends of the support mechanism generally adopt mechanical or hydraulic control, and are unable to adjust the support axial force as the temperature in the foundation pit changes; moreover, when the support mechanism located inside the foundation pit is in use, a lot of dust, concrete and other impurities will adhere to its surface, and these impurities will block the markings on the surface of the support mechanism, making it impossible for staff to quickly identify the support mechanism, thereby reducing the efficiency of repairing the faulty support mechanism. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to provide a support structure that automatically adjusts the axial force as the temperature changes.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] Optionally, fixing rods are installed at both ends of the fixing plate close to the two rotating seats, and sockets compatible with the telescopic ends of the telescopic limit rods are provided on the outer walls of both sides of the fixing plate close to the two rotating seats and inside the fixing rods.

[0009] Optionally, a rotating block is rotatably installed inside the two rotating seats, two electric telescopic rods are installed on one end of the two rotating blocks away from the rotating seat, and the two rotating plates are respectively connected to the telescopic ends of the two electric telescopic rods close to them.

[0010] Optionally, the cleaning mechanism includes a first groove opened inside the two rotating plates, a first screw rod is rotatably installed inside the two first grooves, a first moving block is installed on the outer wall of the two first screw rods, and a moving plate is installed on the adjacent ends of the two first moving blocks.

[0011] Optionally, a second groove is formed inside the two movable plates, a second screw rod is rotatably installed inside the two second grooves, and a second movable block is installed on the outer walls of the two second screw rods.

[0012] Optionally, a fixed seat is installed at one end of the two second moving blocks away from the second screw rod, and an arc-shaped plate adapted to the outer wall of the steel support is rotatably installed inside the two fixed seats.

[0013] Optionally, the two arc-shaped plates are provided with arc-shaped grooves on the arc-shaped outer walls close to the steel support, air bags are installed inside the two arc-shaped grooves, and scrapers are installed on both sides of the two arc-shaped plates close to the arc-shaped outer walls.

[0014] Optionally, the collecting mechanism includes two mounting plates, which are respectively mounted on the bottom of the fixed plate and the steel support by bolt threads, telescopic curtains are installed on the outer walls of the two mounting plates on the side close to each other, rectangular strips for supporting the telescopic curtains are installed between the two mounting plates, connecting plates are installed on the ends of the two telescopic curtains that are close to each other, and notches matching the rectangular strips are opened in the center positions of the two connecting plates.

[0015] Optionally, two guide rods are arranged between the two mounting plates, and guide grooves are provided on the outer walls on the sides where the two guide rods are close to each other, and both ends of the two connecting plates are respectively located in the guide grooves, and rectangular grooves are provided on both ends of the two mounting plates, and sliding rods are installed inside the two rectangular grooves, and springs are installed on the outer walls of the two sliding rods, and the two ends of the two guide rods are respectively slidably connected to the outer walls of the sliding rods close to them, and the bottoms of both ends of the two guide rods abut against the top of the springs below.

[0016] The beneficial effects of the present invention are:

[0017] 1. In this invention, since the concrete inside the foundation pit has the property of thermal expansion and contraction, the temperature inside the foundation pit is monitored in real time by means of temperature sensors arranged at the bottom of the two supporting parts. The temperature sensors transmit the temperature data inside the foundation pit to the controller. The controller can control the servo drive mechanism to drive the two supporting parts to extend and retract, and can control the axial force between the two supporting parts and the foundation pit to increase or decrease, so that the two supporting parts can adjust the axial force according to the temperature changes inside the foundation pit, ensuring that the steel supports and the supporting parts can stably support the inside of the foundation pit.

[0018] 2. In the invention, if impurities such as dust and concrete are found attached to the surface of the steel support, the two telescopic curtains located at the bottom of the steel support are both in an unfolded and docked state, and the arc-shaped outer walls of the two arc-shaped plates are in contact with the outer wall of the steel support. The first screw is controlled to drive the arc-shaped plate to move back and forth on the surface of the steel support, so that the scraper can scrape the dust, concrete and other impurities attached to the surface of the steel support to the top of the telescopic curtain below for collection, and by controlling the extension of the corresponding two electric telescopic rods, the rotating plate is driven to move together in the direction away from the support part, so that the scraper can clean the dust and concrete on the surface of the steel support more comprehensively.

[0019] 3. In the invention, after the scraper has cleaned the impurities on the surface of the steel support, the two movable plates are controlled to be located in the center of the steel support, and then the second movable block is controlled to drive the fixed seat and the arc plate to move downward together, so that the bottom ends of the two fixed seats press the center positions of the two guide rods respectively, causing the two guide rods to drive the two unfolded telescopic curtains to bend downward at both ends. The center positions of the two telescopic curtains can still be supported by the rectangular strips without changing, so that the impurities collected on the top of the two telescopic curtains can slide down from the bottom ends of the steel support, avoiding collisions and secondary pollution to other steel supports below.

[0020] 4. In the invention, after the steel support is used, it needs to be lifted up from the inside of the foundation pit with the help of lifting equipment. In order to ensure the stable connection between the steel wire rope and the steel support, and that the steel wire rope and the outer wall of the steel support do not slide during the lifting process, the two first screw rods are controlled to respectively drive the two arc plates to move to appropriate positions on the surface of the steel support, and the two arc plates are in a dislocated state. Then the steel wire rope is tied between the two arc plates, and then the two arc plates are controlled to move in a direction close to each other, so that the two arc plates can have a clamping and limiting effect on the steel wire rope, thereby preventing the steel wire rope from sliding during the lifting process.

[0036] As a technical optimization solution of the present invention, the cleaning mechanism includes a first groove 16 opened inside the two rotating plates 6, and the first screw rods 17 are rotatably installed inside the two first grooves 16, and the outer walls of the two first screw rods 17 are installed with first moving blocks, and the ends of the two first moving blocks that are close to each other are installed with moving plates 19. In actual use, the outer walls of one side of the two rotating plates 6 are pre-installed with first driving devices, and the output ends of the two first driving devices are respectively connected to one end of the two first screw rods 17, so that the first screw rods 17 can be driven to rotate inside the first groove 16, so that the first moving block drives the moving plate 19 to move back and forth on the outer wall of the rotating plate 6.

[0037] As a technical optimization solution of the present invention, the two movable plates 19 are provided with second grooves 23 inside, the second screw rods 24 are rotatably installed inside the two second grooves 23, and the outer walls of the two second screw rods 24 are installed with second movable blocks 22. In actual use, the outer walls of one side of the two movable plates 19 are pre-installed with second driving devices, and the output ends of the two second driving devices are respectively connected to one end of the two second screw rods 24, so as to drive the second screw rods 24 to rotate inside the second grooves 23, and drive the two second movable blocks 22 to move back and forth on the outer walls of the second screw rods 24.

[0038] As a technical optimization solution of the present invention, the ends of the two second moving blocks 22 away from the second screw rod 24 are both installed with a fixed seat 20, and the inside of the two fixed seats 20 are both rotatably installed with an arc-shaped plate 5 adapted to the outer wall of the steel support 2. In actual use, the outer wall of one side of the two fixed seats 20 is pre-installed with a third driving device, and the output ends of the two third driving devices are respectively connected to the rotating parts of the two arc-shaped plates 5, so as to drive the arc-shaped plates 5 to rotate inside the fixed seat 20.

[0039] As a technical optimization solution of the present invention, the arc-shaped outer walls of the two arc-shaped plates 5 close to the steel support 2 are both provided with arc-shaped grooves 21, airbags are installed inside the two arc-shaped grooves 21, and scrapers 18 are installed on both sides of the two arc-shaped plates 5 close to the arc-shaped outer walls. The airbags installed inside the arc-shaped grooves 21 are semicircular after being inflated, and when the two arc-shaped plates 5 are connected to form a complete circle, the two airbags can be connected to each other to form a circle; and the outer walls of the airbags are bonded with wear-resistant coatings to increase the service life of the airbags.

[0040] As a technical optimization solution of the present invention, the collecting mechanism includes two mounting plates 7, which are respectively mounted on the bottom of the fixing plate 4 and the steel support 2 by bolt threads, and the outer walls of the two mounting plates 7 on the adjacent side are both mounted with telescopic curtains 8, and a rectangular strip 26 for supporting the telescopic curtains 8 is mounted between the two mounting plates 7, and a connecting plate 27 is mounted on the adjacent ends of the two telescopic curtains 8, and the center positions of the two connecting plates 27 are both provided with notches adapted to the rectangular strips 26. Pulling the two connecting plates 27 in the approaching direction respectively drives the two telescopic curtains 8 to unfold on the top of the rectangular strips 26, so as to facilitate the collection of impurities falling downward from the surface of the steel support 2.

[0041] As a technical optimization solution of the present invention, two guide rods 25 are arranged between the two mounting plates 7, and the outer wall of the side where the two guide rods 25 are close to each other is provided with a guide groove 28, and the two ends of the two connecting plates 27 are respectively located in the guide groove 28, and the two ends of the two mounting plates 7 are provided with a rectangular groove 29, and the inside of the two rectangular grooves 29 is provided with a slide rod 31, and the outer wall of the two slide rods 31 is provided with a spring 30, and the two ends of the two guide rods 25 are respectively connected with the outer wall of the slide rod 31 close to each other, and the bottom of the two ends of the two guide rods 25 are in contact with the top of the spring 30 below. The two guide rods 25 located on both sides of the telescopic curtain 8 can guide and limit the movement of the connecting plate 27, and because the two guide rods 25 are connected with the slide rod 31 and the rectangular groove 29 in a sliding manner, the two ends of the telescopic curtain 8 can be driven to bend downward by pressing the two guide rods 25 downward, so that the impurities on the top of the telescopic curtain 8 can be quickly discharged downward from both sides of the telescopic curtain 8.

[0042] In the present invention, when the user uses the device, after placing the steel support 2 inside the foundation pit 1, the two mounting plates 7 are respectively installed on the fixing plate 4 and the bottom of the steel support 2 by bolts, so as to facilitate the installation of the collecting mechanism on the bottom of the steel support 2, and then the two connecting plates 27 are pulled in the direction of approaching each other, and the two connecting plates 27 are connected and fixed by other fixing parts, so that the telescopic curtain 8 in the unfolded state can collect the impurities falling downward from the outer wall of the steel support 2, and avoid continuing to fall downward and causing collisions with the outer walls of other steel supports 2 below; then the servo drive mechanism inside the two support parts 3 is controlled to start, and axial force is applied to the two support parts 3, so that the ends of the two support parts 3 away from the steel support 2 are respectively in contact with the inner walls on both sides of the foundation pit 1, thereby achieving the effect of supporting and fixing the inside of the foundation pit.

[0043] Since the concrete inside the foundation pit 1 has the property of thermal expansion and contraction, the temperature inside the foundation pit 1 is monitored in real time by means of the temperature sensor 9 arranged at the bottom of the two support parts 3. The temperature sensor 9 transmits the temperature data inside the foundation pit 1 to the controller. The controller can control the servo drive mechanism to drive the two support parts 3 to extend and retract, and can control the axial force between the two support parts 3 and the foundation pit 1 to increase or decrease, so that the two support parts 3 can adjust the axial force according to the temperature change inside the foundation pit 1, ensuring that the steel support 2 and the support part 3 can stably support the inside of the foundation pit 1.

[0044] If it is monitored that the axial force exerted on the support part 3 is too large, in order to improve the stability of the steel support 2 during use, the rotating blocks 14 at both ends of the two fixed plates 4 can be controlled to drive the rotating plates 6 to rotate together in the direction close to the support part 3 until the ends of the two rotating plates 6 away from the rotating blocks 14 abut against the inner wall of the foundation pit 1, so that the two rotating plates 6 can disperse the axial force exerted on the support part 3 at this time, thereby reducing the axial force exerted on the support part 3 and improving the overall stability of the steel support 2.

[0045] At the same time, when the steel support 2 is in normal use, the servo drive mechanism needs to control the two support parts 3 to move away from the steel support 2 to ensure that the support part 3 is in close contact with the inner wall of the foundation pit 1, and the two arc plates 5 located on the outside of the steel support 2 can be controlled to rotate to a state parallel to the rotating plate 6, so that the rotating seats 13 at both ends of the fixed plate 4 can drive the corresponding rotating plates 6 to rotate downward until the two rotating seats 13 are rotated to a horizontal state, and the positions of the rotating seats 13 are limited and fixed by means of the two corresponding telescopic limit rods 12. At this time, the rotating plate 6 in a vertical state below the steel support 2 can have an auxiliary supporting effect on the steel support 2, which is convenient for the servo drive mechanism to drive the two support parts 3 to closely contact with the inner wall of the foundation pit 1, avoiding looseness between the support part 3 and the inner wall of the foundation pit 1 during movement, resulting in the risk of the steel support 2 falling off downward.

[0046] And in the process of the steel support 2 supporting the inside of the foundation pit 1, when the two rotating plates 6 are no longer needed, the two arc plates 5 can be controlled to rotate to a state parallel to the rotating plates 6 again, so that the two rotating seats 13 can drive the two rotating plates 6 to rotate upward to a vertical state. At this time, the two arc plates 5 located above the support part 3 can be controlled to rotate and reset, so that the two arc plates 5 located above the support part 3 can be spliced ​​into a complete circle. Then the second moving block 22 can be controlled to drive the arc plates 5 to move on the outer wall of the second screw rod 24, so that the two arc plates 5 can move to the top of the support part 3, and the airbags inside the two arc grooves 21 are controlled to inflate and expand, so that they can form a shielding component above the support part 3, which is convenient for protecting the top of the support part 3 and preventing dust or other debris falling from the edge of the foundation pit 1 from falling on the surface of the support part 3, which affects the use of the support part 3.

[0047] When the steel support 2 is located inside the foundation pit 1 for use, dust, concrete and other impurities will inevitably adhere to its surface. A large amount of dust and concrete adhere to the surface of the steel support 2, which will cover the markings on the surface of the steel support 2. When problems occur during the use of the steel support 2, the staff cannot promptly identify the problematic steel support 2, thereby affecting the efficiency of the inspection and replacement of the steel support 2. If impurities such as dust and concrete are found to be attached to the surface of the steel support 2, refer to Figure 2 As shown, at this time, the two telescopic curtains 8 located at the bottom of the steel support 2 are both in an unfolded and docked state, and the arc-shaped outer walls of the two arc-shaped plates 5 are in contact with the outer wall of the steel support 2. The first screw 17 can be controlled to drive the first moving block and the moving plate 19 to move back and forth, thereby driving the arc-shaped plate 5 to move back and forth on the surface of the steel support 2, so that the scrapers 18 on both sides of the arc-shaped plate 5 can scrape the dust, concrete and other impurities attached to the surface of the steel support 2 to the top of the telescopic curtain 8 below for collection, and by controlling the extension of the corresponding two electric telescopic rods 15, the rotating plate 6 is driven to move together in the direction away from the support part 3, so that the scraper 18 can clean the dust and concrete on the surface of the steel support 2 more comprehensively.

[0048] The impurities that fall on the top of the telescopic curtain 8 in the unfolded state below can be controlled to rotate to a state parallel to the rotating plate 6 after the scraper 18 has cleaned the impurities on the surface of the steel support 2. Then, the two movable plates 19 are controlled to be located in the center position of the steel support 2, and then the second movable block 22 is controlled to drive the fixed seat 20 and the curved plate 5 to move downward together, so that the bottom ends of the two fixed seats 20 press the center positions of the two guide rods 25 respectively, so that the two ends of the two guide rods 25 can slide downward on the outer wall of the slide rod 31, squeezing the spring 30. Since the two ends of the two telescopic curtains 8 are respectively located in the two guide grooves 28, when the two guide rods 25 move downward, the two ends of the unfolded telescopic curtains 8 can be driven to bend downward. The center position of the two telescopic curtains 8 can still be supported by the rectangular strips 26 without changing, so that the impurities collected on the top of the two telescopic curtains 8 can slide down from the bottom ends of the steel support 2, avoiding the problem of bumping and secondary pollution to other steel supports 2 below.

[0049] After the steel support 2 is used, it is necessary to use lifting equipment and wire ropes to lift the steel support 2 upward from the inside of the foundation pit 1. In order to ensure that the connection between the wire rope and the steel support 2 is stable, and that the wire rope and the outer wall of the steel support 2 do not slide during the lifting process, and the accident of colliding with the inner wall of the foundation pit 1 occurs, refer to Figure 2 As shown, the two first screw rods 17 are controlled to respectively drive the two arc plates 5 to move to appropriate positions on the surface of the steel support 2, and the two arc plates 5 are in a staggered state, that is, one arc plate 5 is in front and the other arc plate 5 is in the back, and then the wire rope is tied between the two arc plates 5, and then the two arc plates 5 are controlled to move in a direction close to each other, so that the two arc plates 5 can have a clamping and limiting effect on the wire rope, thereby preventing the wire rope from sliding during the lifting process.

[0050] And refer to Figure 6 As shown, the end of the scraper 18 away from the arc plate 5 is an inclined sharp portion. The two arc plates 5 move toward each other, which can drive the sharp portions of the two scrapers 18 to abut against each other, so that the sharp portions of the two scrapers 18 can protect the bolting part of the steel support 2, avoid the steel wire rope directly rubbing against the surface of the steel support 2, and damage the coating on the surface of the steel support 2, causing the steel support 2 to rust during subsequent use, which indirectly has a protective effect on the steel support 2.
