Description

Technical Field

[0001] This utility model relates to the field of drainage pipe trench technology, and in particular to an automatic earthwork support device for excavating drainage pipe trenches. Background Technology

[0002] Drainage trenches are linear underground trench structures used for laying drainage pipes. They are mainly used to collect and transport rainwater, sewage, or industrial wastewater, and to prevent surface water accumulation, soil erosion, and foundation softening. Their structure typically includes an excavated trench, a bottom bedding layer, drainage pipes (such as concrete pipes or HDPE pipes), backfill material, and a top covering layer. In some complex scenarios, inspection wells, filter layers, or seepage prevention facilities may also be installed.

[0003] In the prior art, for example, Chinese Patent Publication No. CN218540724U discloses an excavation support device for municipal water supply and drainage pipeline trenches, which includes a support box, a first support assembly, and a second support assembly. The first support assembly has one set at each end of the support box along its length. The first support assembly includes a support plate parallel to the end face of the support box. A first driving member is provided on the support box, which drives the support plate to move along the length of the support box. The second support assembly is disposed on the bottom surface of the support box and includes a support rod assembly and a second driving member. The support rod assembly includes a sleeve rod and a sliding rod slidably connected to the sleeve rod. The sleeve rod is connected to the bottom end of the support rod. The second driving member drives the sliding rod to move. This application has the advantage of wide applicability.

[0004] While the above-mentioned solution has the advantages mentioned above, its disadvantages are as follows: although it can support trenches of different sizes through the cooperation of the support box, the first support component, and the second support component, and has a wide range of applications, the movement of the support device is time-consuming and laborious when the support position needs to be changed, resulting in low ease of use of the support device. In addition, the area of ​​the pressure sensor in direct contact with the soil of the drainage pipe trench is small. When the soil has a certain degree of moisture, the pressure sensor is easy to insert into the soil of the drainage pipe trench, resulting in inaccurate pressure detection results on the support plate. Utility Model Content

[0005] The purpose of this invention is to solve the problems in the existing technology, which, although it can support trenches of different sizes through the cooperation of the support box, the first support component, and the second support component, and has a wide range of applications, is time-consuming and laborious to move when the support position needs to be changed, resulting in low convenience of use. In addition, the area of ​​the pressure sensor in direct contact with the soil of the drainage pipe trench is small. When the soil has a certain degree of moisture, the pressure sensor is easy to insert into the soil of the drainage pipe trench, resulting in inaccurate pressure detection results on the support plate.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: an automatic earthwork support device for excavating drainage trenches, comprising: a support box, and further comprising:

[0007] Two base plates are respectively set on opposite sides of the support box. Two universal self-locking wheels are symmetrically fixedly connected to the bottom of the base plates. Two hollow columns are symmetrically fixedly connected to the top of the base plates. Sliding columns are slidably connected inside the hollow columns. Connecting strips are fixedly connected to the top of the two sliding columns. Two connecting rods are symmetrically fixedly connected to the opposite side of the two connecting strips. U-shaped frames are fixedly connected to the outer surfaces of the two connecting rods. Round rods are fixedly connected to the opposite side of the two arms of the U-shaped frames. Two fixing blocks are symmetrically fixedly connected to the top of the support box. The fixing blocks are rotatably connected to round rods. An electric telescopic rod is fixedly connected to the top of the base plates. The electric telescopic rod is fixedly connected to the connecting strips.

[0008] Preferably, two movable rods are symmetrically slidably connected to opposite sides of the support box, and one end of each movable rod is fixedly connected to a connecting plate.

[0009] Preferably, each of the four corners of one side of the connecting plate is slidably connected to a movable rod, and the multiple movable rods are divided into two groups, with a support plate fixedly connected to one end of each group of movable rods.

[0010] Preferably, a limit ring is fixedly connected to the other end of the movable rod, a return spring is provided on the outer surface of the movable rod, the return spring is fixedly connected to the connecting plate and the support plate respectively, and a pressure sensor is fixedly connected to one side of the connecting plate.

[0011] Preferably, the other ends of the two movable rods are fixedly connected to slide bars, and two slide grooves are symmetrically opened on opposite sides of the inner wall of the support box, and the outer surface of the slide bar is slidably connected to the inside of the two slide grooves.

[0012] Preferably, a rotating rod is rotatably connected to the top of the support box, a gear is fixedly connected to one end of the rotating rod, and a rack is fixedly connected to one side of the slide bar, with both racks meshing with the gear.

[0013] Preferably, a motor is fixedly connected to the top of the support box, and the output end of the motor is fixedly connected to the other end of the rotating rod.

[0014] Preferably, an electric telescopic rod is rotatably connected to the outer surface of the first round rod, a U-shaped block is fixedly connected to the top of the support box, a second round rod is fixedly connected to one side of the two arms of the U-shaped block, the second round rod is rotatably connected to the first electric telescopic rod, and a level sensor is fixedly connected to the top of the support box.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] 1. This utility model, with the cooperation of universal self-locking wheels, and with the cooperation of the base plate, hollow column, sliding column connecting strip, electric telescopic rod II, connecting rod, U-shaped frame, round rod I and fixing block, can move this device to the position that needs support. This makes it easy to move this device to the position that needs support, saving time and effort, thereby improving the convenience of using this device.

[0017] 2. In this utility model, the controller starts the motor, causing its output shaft to drive the rotating rod and gear to rotate. Then, with the gear and two racks meshing, the two racks can move to opposite positions, synchronously pushing the slide bar to slide to one side along the inside of the slide groove. This causes the movable rod two to slide from the inside of the support box to the outside, synchronously driving the connecting plate, movable rod one, and support plate to move to one side. This brings the support plate into contact with the soil in the drainage ditch, where it is compressed, causing the support plate to move towards the connecting plate. Simultaneously, the movable rod one slides to one side, compressing the return spring. When the support plate contacts the pressure sensor, the pressure sensor can detect the compressive force on the support plate and connecting plate. By making the entire support plate in contact with the soil in the drainage ditch, the contact area is increased, preventing the pressure sensor from being directly inserted into the soil and causing inaccurate pressure detection on the connecting plate and support plate.

[0018] 3. This utility model uses a controller to activate the electric telescopic rod, causing it to retract and move the connecting strip, connecting rod, U-shaped frame, and support box downwards a suitable distance. Simultaneously, the sliding column slides into the hollow column, moving the support box into the drainage ditch. This allows for appropriate raising and lowering of the support box, enabling it to move into or out of the drainage ditch, which is relatively simple and convenient.

[0019] 4. This utility model controls the start of the electric telescopic rod by a controller, causing it to extend or retract. With the cooperation of the U-shaped blocks, a pushing or pulling force is applied to the support box, causing the support box to drive the fixed block to rotate upward or downward around the outer surface of the circular rod one at an appropriate angle. Simultaneously, both ends of the electric telescopic rod one rotate around the circular rod one and the circular rod two at appropriate angles, keeping the support box in a horizontal position. In this way, when the ground is uneven and the support box tilts, the support box can be adjusted appropriately to keep it in a horizontal state. Attached Figure Description

[0026] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0028] Examples, such as Figure 1-4 As shown, this utility model provides an automatic earthwork support device for excavating drainage pipe trenches, including: a support box 1, and two base plates 3, respectively set on opposite sides of the support box 1. Two universal self-locking wheels 301 are symmetrically fixedly connected to the bottom of the base plates 3, and two hollow columns 302 are symmetrically fixedly connected to the top of the base plates 3. Sliding columns 303 are slidably connected inside the hollow columns 302. Connecting strips 304 are fixedly connected to the top of the two sliding columns 303. Two connecting rods 306 are symmetrically fixedly connected to the opposite side of the two connecting strips 304. U-shaped frames 307 are fixedly connected to the outer surface of the two connecting rods 306. Round rods 103 are fixedly connected to the opposite side of the two arms of the U-shaped frame 307. Two fixing blocks 102 are symmetrically fixedly connected to the top of the support box 1. The fixing blocks 102 are rotatably connected to the round rods 103. Electric telescopic rods 305 are fixedly connected to the top of the base plates 3. Electric telescopic rods 305 are fixedly connected to the connecting strips 304.

[0029] Furthermore, such as Figure 1-4 As shown, two movable rods 210 are symmetrically slidably connected on opposite sides of the support box 1. One end of each movable rod 210 is fixedly connected to a connecting plate 2. With the above arrangement, when the movable rod 210 slides, it can drive the connecting plate 2 to move to one side.

[0030] Furthermore, such as Figure 1-4 As shown, movable rods 202 are slidably connected at the four corners of one side of the connecting plate 2. The multiple movable rods 202 are divided into two groups. One end of each group of movable rods 202 is fixedly connected to a support plate 201. With the above arrangement, when the support plate 201 is squeezed, the movable rods 202 can slide to one side along the inside of the connecting plate 2, so that the support plate 201 moves closer to the connecting plate 2.

[0031] Furthermore, such as Figure 1-4 As shown, a limit ring 204 is fixedly connected to the other end of the movable rod 202. A return spring 203 is provided on the outer surface of the movable rod 202. The return spring 203 is fixedly connected to the connecting plate 2 and the support plate 201 respectively. A pressure sensor 211 is fixedly connected to one side of the connecting plate 2. The limit ring 204 plays a certain limiting role. Under the reset force of the return spring 203, the support plate 201 can be moved away from the connecting plate 2, preventing the support plate 201 from being in constant contact with the pressure sensor 211.

[0032] Furthermore, such as Figure 1-4 As shown, the other ends of the two movable rods 210 are fixedly connected to slide bars 209. Two slide grooves 107 are symmetrically opened on opposite sides of the inner wall of the support box 1. The outer surface of the slide bar 209 is slidably connected to the inside of the two slide grooves 107. Through the above arrangement, the slide bar 209 can slide along the inside of the slide groove 107 to play a certain supporting role.

[0033] Furthermore, such as Figure 1-4 As shown, a rotating rod 206 is rotatably connected to the top of the support box 1. A gear 207 is fixedly connected to one end of the rotating rod 206, and a rack 208 is fixedly connected to one side of the slide bar 209. Both racks 208 are meshed with the gear 207. With the meshing of the gear 207 and the two racks 208, when the gear 207 rotates, the two racks 208 can move to opposite positions.

[0034] Furthermore, such as Figure 1-4 As shown, a motor 205 is fixedly connected to the top of the support box 1. The output end of the motor 205 is fixedly connected to the other end of the rotating rod 206. The motor 205 is started by the controller, so that its output shaft drives the rotating rod 206 to rotate.

[0035] Furthermore, such as Figure 1-4 As shown, an electric telescopic rod 104 is rotatably connected to the outer surface of the circular rod 103. A U-shaped block 105 is fixedly connected to the top of the support box 1. A circular rod 106 is fixedly connected to one side of the two arms of the U-shaped block 105. The circular rod 106 is rotatably connected to the electric telescopic rod 104. A horizontal sensor 101 is fixedly connected to the top of the support box 1. The controller controls the electric telescopic rod 104 to start, so that it extends or retracts. With the cooperation of the U-shaped block 105, a pushing or pulling force is applied to the support box 1, so that the support box 1 drives the fixed block 102 to rotate up or down around the outer surface of the circular rod 103 by an appropriate angle. At the same time, the two ends of the electric telescopic rod 104 rotate around the circular rod 103 and the circular rod 106 by an appropriate angle, respectively.

[0036] Working principle: In use, with the cooperation of the universal self-locking wheel 301, this device is moved above the drainage ditch, so that the support box 1 is directly above the drainage ditch. The level sensor 101 detects the levelness of the support box 1. When the support box 1 is not level, the controller activates the electric telescopic rod 104 to extend or retract. With the cooperation of the U-shaped block 105, a pushing or pulling force is applied to the support box 1, causing the support box 1 to drive the fixed block 102 to rotate up or down an appropriate angle around the outer surface of the round rod 103. Simultaneously, the two ends of the electric telescopic rod 104 rotate around the round rod 103 and the round rod 106 respectively by appropriate angles, so that the support box 1 is kept in a level position. When the support box 1 is uneven and tilts, it can be adjusted to keep it level. Then, the electric telescopic rod 305 is activated by the controller to retract, causing the connecting bar 304, connecting rod 306, U-shaped frame 307, and support box 1 to move downwards a suitable distance. Simultaneously, the sliding column 303 slides into the hollow column 302, moving the support box 1 into the drainage ditch. This allows for appropriate raising and lowering of the support box 1, moving it into or out of the drainage ditch in a simple and convenient manner. Then, the motor 205 is activated by the controller, causing its output shaft to drive the rotating rod 206 and gear 207 to rotate. Next, the gear 207 and the two racks 208... With the meshing engaged, the two racks 208 can move in opposite directions, simultaneously pushing the slide bar 209 to slide to one side along the inside of the slide groove 107. This causes the movable rod 210 to slide from the inside of the support box 1 to the outside, simultaneously driving the connecting plate 2, the movable rod 202, and the support plate 201 to move to one side. This brings the support plate 201 into contact with the soil in the drainage ditch, where it is compressed. This causes the support plate 201 to move towards the connecting plate 2, simultaneously causing the movable rod 202 to slide to one side, compressing the return spring 203. When the support plate 201 contacts the pressure sensor 211, the pressure sensor 211 can detect the compressive force on the support plate 201 and the connecting plate 2. In this way, by bringing the entire support plate 201 into contact with the soil in the drainage ditch, To increase the contact area and prevent the pressure sensor 211 from being directly inserted into the soil of the drainage ditch, which could cause inaccurate pressure detection on the connecting plate 2 and the support plate 201, the controller controls the motor 205 to rotate in the opposite direction. With the cooperation of the gear 207 and the rack 208, the movable rod 210 slides into the support box 1, simultaneously moving the connecting plate 2 and the support plate 201 to one side of the support box 1, releasing the support from the drainage ditch soil. Then, with the cooperation of the universal self-locking wheel 301, and the base plate 3, hollow column 302, sliding column 303, connecting strip 304, electric telescopic rod 2 305, connecting rod 306, U-shaped frame 307, round rod 103, and fixing block 102,This device can be moved to the location where support is needed, making it easy to move and saving time and effort, thus improving its ease of use.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
