Description
Technical Field
[0001] This utility model relates to an anti-collapse support device, specifically an anti-collapse support device suitable for municipal underground pipeline construction. Background Technology
[0002] With the acceleration of urbanization, the scale of municipal underground pipeline construction is expanding daily. These pipelines encompass various vital infrastructures such as water supply, drainage, gas, electricity, and communications, and their construction quality and safety directly impact the normal operation of the city and the lives of residents. Anti-collapse support devices are required during the construction of underground pipelines.
[0003] Currently, existing anti-collapse measures on the market have many limitations. Some simple support structures, such as wooden planks, although low in cost and easy to process, have poor strength and durability. Under significant soil pressure or prolonged exposure to damp environments, they are prone to rotting and deformation, failing to provide reliable support and leading to support failure, which in turn causes soil collapse. Other metal supports, while having high strength, often suffer from being heavy and inconvenient to install. Furthermore, they lack adaptability in complex and variable underground construction environments, making it difficult to flexibly adjust them according to different pipe diameters, soil types, and construction conditions.
[0004] Therefore, this utility model provides an anti-collapse support device suitable for municipal underground pipeline construction to solve the above-mentioned problems. Utility Model Content
[0005] The purpose of this invention is to provide an anti-collapse support device suitable for municipal underground pipeline construction, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A collapse-prevention support device suitable for municipal underground pipeline construction includes a base, a support frame mounted on the upper surface of the base, a support mechanism for supporting the soil inside the pipeline tunnel mounted on the outer end of the support frame, a limiting mechanism for positioning the use position of the support mechanism being slidably connected inside the support mechanism, and a warning component for indicating the use position of the limiting mechanism being mounted on the outer end of the limiting mechanism and the base.
[0008] As a further embodiment of this utility model, the support mechanism includes a motor, which is mounted on the top of the inner wall of the support frame. The output shaft of the motor passes through the support frame and is fitted with a second bevel gear. A magnetic rod is magnetically connected inside the second bevel gear, and a first bevel gear is mounted on the top of the magnetic rod. A first screw is mounted on the upper surface of the first bevel gear, and a top rod is threaded onto the outside of the first screw.

An L-shaped fixing plate is mounted on the side of the side plate near the second bevel gear, and a second screw is threaded onto the inside of the L-shaped fixing plate. A third bevel gear is slidably connected to the outer end of the second screw, and the outer teeth of the third bevel gear mesh with the inside of the second bevel gear.
[0009] As a further embodiment of this utility model, the limiting mechanism includes a connecting plate, which is slidably connected inside the support plate. Three sets of insert rods are installed at the lower end of the connecting plate, and a push rod is installed on the front side of the connecting plate.
[0010] As a further embodiment of this utility model, the warning component includes two sets of contact switches, which are respectively installed on the lower surfaces of the two sets of connecting plates. An LED strip is installed on the upper surface of the base, and the control terminals of the two sets of contact switches and the LED strip are electrically connected.
[0011] As a further embodiment of this utility model, two sets of protective plates are installed on the upper surface of the support frame, and the two sets of protective plates are located on the front and rear sides of the two sets of bevel gears three, one bevel gear, and two bevel gears.

[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. When using this utility model, by activating the support mechanism, its left and right sides respectively abut against the inner walls of the left and right sides of the tunnel, and drive the equipment on the left and right sides of the support mechanism to move upward, adjusting the equipment on the left and right sides of the support mechanism to a position parallel to the extension direction of the tunnel, so that workers can complete the full support of the tunnel interior by activating a single set of support mechanisms. Compared with traditional anti-collapse devices, the anti-collapse support device of this application can adapt to complex and changeable underground construction environments, and can also be flexibly adjusted according to different pipe diameters, soil types and construction conditions, making it more practical.

Detailed Implementation
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figures 1-4In this embodiment of the utility model, an anti-collapse support device suitable for municipal underground pipeline construction includes a base 1, a support frame 2 installed on the upper surface of the base 1, a support mechanism 3 for supporting the soil of the inner wall of the pipeline tunnel installed at the outer end of the support frame 2, a limiting mechanism 7 for positioning the use position of the support mechanism 3 is slidably connected inside the support mechanism 3, and a warning component 4 for warning the use position of the limiting mechanism 7 is installed at the outer end of the limiting mechanism 7 and the base 1.
[0023] Specifically, by activating the support mechanism 3, the left and right sides of the support mechanism 3 are pushed to abut against the inner walls of the left and right sides of the tunnel, and the equipment on the left and right sides of the support mechanism 3 is moved upward. The equipment on the left and right sides of the support mechanism 3 is adjusted and moved to a position parallel to the tunnel opening. This allows the workers to complete the full support of the tunnel interior by activating a single set of support mechanisms 3. In this way, the device can complete the full support of the tunnel with a single set of drive equipment, thereby reducing the production cost of the device and improving its practicality.
[0024] Please see Figures 1-4The support mechanism 3 includes a motor 308, which is mounted on the top of the inner wall of the support frame 2. The output shaft of the motor 308 passes through the support frame 2 and is fitted with a bevel gear 307. A magnetic rod 309 is magnetically connected inside the bevel gear 307. A bevel gear 305 is mounted on the top of the magnetic rod 309. A screw 306 is mounted on the upper surface of the bevel gear 305. A push rod 310 is threaded onto the outside of the screw 306. Support plates 314 are mounted on both sides of the push rod 310. The interiors of both sets of support plates 314 are... A side plate 301 is slidably connected. An L-shaped fixing plate 316 is installed on the side of the side plate 301 near the second bevel gear 307. A screw 313 is threadedly connected to the inside of the L-shaped fixing plate 316. A bevel gear 311 is slidably connected to the outer end of the screw 313. The external teeth of the bevel gear 311 are engaged with the inside of the second bevel gear 307. An L-shaped fixing bracket 302 is rotatably connected to the outer surface of the first screw 306. The lower surface of the L-shaped fixing bracket 302 is installed on the upper surface of the support frame 2. The inner wall of the first bevel gear 305 is fitted with... A connecting rod 304 is provided, with a groove on its lower surface. A magnetic rod 309 is slidably connected inside the groove of the connecting rod 304. A through hole is provided on the upper surface of the support frame 2. The output shaft of the motor 308 passes through the through hole inside the support frame 2 and is fitted with a fixing rod 315. A bevel gear 307 is installed on the outer surface of the fixing rod 315. A groove is provided on the upper surface of the fixing rod 315. The groove inside the fixing rod 315 is located on the moving path of the magnetic rod 309. The fixing rod 315 is made of iron. A screw 3... The outer surface of 13 is rotatably connected to a support rod 312, which is installed on the upper surface of the support frame 2. The outer surface of the screw 2 313 has a slot, and the bevel gear 311 is slidably connected inside the slot of the bevel gear 311. The L-shaped fixing plate 316 has a threaded hole inside, and the external thread of the screw 2 313 is connected inside the threaded hole of the L-shaped fixing plate 316. The lower surface of the L-shaped fixing plate 316 abuts against the upper surface of the support frame 2. The front and rear sides and the upper surface of the support plate 314 are all equipped with arc-shaped extrusion plates 303.
[0025] Specifically, the starting motor 308 drives the second bevel gear 307, two sets of screws 313, and the first bevel gear 305 to rotate. During rotation, the two sets of screws 313 drive the L-shaped fixing plate 316 to move the side plate 301 and support plate 314, causing the side of the support plate 314 away from the support frame 2 to abut against the inner wall of the tunnel. Simultaneously, the first bevel gear 305, during rotation, pushes the top rod 310, moving the two sets of support plates 314 upwards, thus expanding the contact area between the support mechanism 3 and the inner wall of the tunnel, minimizing the risk of tunnel collapse during pipeline installation. When the tops of the two sets of support plates 314 are adjusted to be parallel to the tunnel opening, the magnetic rod 309 is pushed out of the groove of the fixing rod 315, disconnecting the fixing rod 315 and the magnetic rod 309. This prevents the second bevel gear 307 from driving the first bevel gear 305 during rotation, further minimizing the risk of tunnel collapse during pipeline installation. When the support plates 314 are positioned on the left and right sides, the tops of the two sets of support plates 314 are moved out of the tunnel. When the two sets of support plates 314, on the side away from the support frame 2, respectively abut against the inner walls of the left and right sides of the tunnel, the two sets of bevel gears 311 are pushed to slide inside the slots of the screw 2 313, disconnecting the external teeth of the bevel gears 311 from the internal teeth of the bevel gear 2 307. This avoids the motor 308 being unable to adjust the height normally due to the limited movement of the two sets of support plates 314 on the left and right sides during the upward movement of the two sets of support plates 314. The arc-shaped extrusion plate 303 is positioned on the moving path of the support plates 314, so that the support plates 314 can use the arc-shaped extrusion plate 303 to extrude excess soil from the inner wall of the tunnel during the forward, backward, and upward movement of the support plates 314. This avoids the tunnel from collapsing due to the movement of excess soil during the forward, backward, and upward movement of the support plates 314.
[0026] Please see Figure 1 and Figure 2 The limiting mechanism 7 includes a connecting plate 702, which is slidably connected to the inside of the support plate 314. Three sets of insert rods 703 are installed at the lower end of the connecting plate 702, and a push rod 701 is installed on the front of the connecting plate 702. A slot is opened on the lower surface of the support plate 314, and the connecting plate 702 is slidably connected to the inside of the slot of the support plate 314.
[0027] Specifically, by pressing the push rod 701, the connecting plate 702 is pushed to slide inside the slot of the support plate 314, and multiple sets of insert rods 703 are inserted into the ground. This restricts the movement of the bottom of the support plate 314 by the limiting mechanism 7, thereby minimizing the tilting of the bottom of the support plate 314 during the process of being squeezed by earthwork. The connecting plate 702 is slidably connected inside the slot of the support plate 314, allowing the support plate 314 to slide normally at the outer end of the connecting plate 702, thereby minimizing the obstruction of the support plate 314 from normal height adjustment by the connecting plate 702.
[0028] Please see Figure 2 and Figure 3 The warning component 4 includes two sets of contact switches 401, which are respectively installed on the lower surface of two sets of connecting plates 702. A light strip 402 is installed on the upper surface of the base 1. The control terminals of the two sets of contact switches 401 and the light strip 402 are electrically connected.
[0029] Specifically, two sets of contact switches 401 are located at the lower ends of the two sets of connecting plates 702. When the two sets of connecting plates 702 drive multiple sets of plug rods 703 to be inserted into the tunnel floor, the contact switches 401 are triggered to turn on the light strip 402. This causes the light strip 402 to alert the workers that multiple sets of plug rods 703 have been inserted into the tunnel floor. This helps to prevent workers from moving the device before the connecting plates 702 are reset, which could cause the support plate 314 to shift and damage the support mechanism 3.
[0030] Please see Figures 1-3 The upper surface of the support frame 2 is equipped with two sets of protective plates 5. The two sets of protective plates 5 are located on the front and rear sides of the two sets of bevel gears 311, 305 and 307. The upper surface of the support frame 2 is provided with two sets of positioning slots. The two sets of protective plates 5 are respectively engaged in the two sets of positioning slots of the support frame 2.
[0031] Specifically, by pushing the two sets of protective plates 5, the two sets of protective plates 5 are respectively snapped into the two sets of positioning slots of the support frame 2, so that the two sets of protective plates 5 shield the upper part of the equipment of the support frame 2, thereby minimizing the risk of workers being injured by collisions with the two sets of bevel gears 311, 305 and 307 during the operation. This improves the safety of the device during use.
[0032] Please see Figures 1-3 Limiting rods 6 are slidably connected to both the left and right sides of the support frame 2. The side of the limiting rod 6 away from the support frame 2 is installed on the side plate 301 near the support frame 2. Grooves are provided on both the left and right sides of the support frame 2, and the limiting rods 6 are slidably connected inside the grooves of the support frame 2.
[0033] Specifically, by installing a limiting rod 6 on one side of the side plate 301, the side plate 301 moves during movement, pulling the limiting rod 6 to move inside the slot of the support frame 2. This limits the movement path of the bottom end of the side plate 301, thereby minimizing the bending of the connection between the side plate 301 and the L-shaped fixing plate 316 when subjected to large pressure, thus improving the service life of the support mechanism 3.
[0034] The working principle of this utility model is as follows: When the device is moved to the construction position, the motor 308 is first started to drive the bevel gear 307, the two sets of screws 313, and the bevel gear 305 to rotate. During the rotation of the two sets of screws 313, the L-shaped fixing plate 316 drives the side plate 301 and the support plate 314 to move, so that the side of the support plate 314 away from the support frame 2 abuts against the inner wall of the tunnel. During the rotation of the bevel gear 305, the top rod 310 is pushed to move the two sets of support plates 314 upward, thereby expanding the contact area between the support mechanism 3 and the inner wall of the tunnel, thus minimizing the risk of tunnel collapse during pipeline installation. When the tops of the two sets of support plates 314 are adjusted to be parallel to the tunnel opening, the magnetic rod 309 is pushed to move it out of the groove of the fixing rod 315, thus disconnecting the fixing rod 315 and the magnetic rod 309. This prevents the second bevel gear 307 from driving the first bevel gear 305 to rotate during rotation, thereby minimizing the risk of workers moving the tops of the two sets of support plates 314 out of the tunnel when adjusting the left and right sides of the two sets of support plates 314. When the side of the two sets of support plates 314 away from the support frame 2 abuts against the inner walls of the left and right sides of the tunnel, the third bevel gear 311 is pushed to slide in the slot of the second screw 313, disconnecting the external teeth of the third bevel gear 311 from the internal teeth of the second bevel gear 307. This minimizes the risk of the motor 308 being unable to properly adjust the height when driving the two sets of support plates 314 upward because the left and right sides of the two sets of support plates 314 are restricted in their movement. Then, pressing the push rod 701 pushes the connecting plate 702 to slide within the slot of the support plate 314, inserting multiple sets of insertion rods 703 into the ground. This restricts the movement of the bottom of the support plate 314 by the limiting mechanism 7, thus minimizing the risk of tilting of the bottom of the support plate 314 during soil compression. When the insertion rods 703 are inserted into the tunnel floor, the contact switch 401 is triggered to turn on the light strip 402, thereby alerting workers that multiple sets of insertion rods 703 have been inserted into the tunnel floor. This minimizes the risk of workers moving the device before the connecting plate 702 is reset, which could cause the support plate 314 to shift and damage the support mechanism 3. Compared with traditional anti-collapse measures, the anti-collapse support device of this application can adapt to complex and varied underground construction environments and can be flexibly adjusted according to different pipe diameters, soil types, and construction conditions, making it more practical. Moreover, construction personnel can promptly grasp the working status information of the support structure, thereby minimizing the possibility of damage to the support mechanism 3 caused by workers pushing the device when the connecting plate 702 is not reset, resulting in the position of the support plate 314 shifting.
[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
