Description

Technical Field

[0001] This utility model relates to the technical field of pipeline trench excavation and support, specifically a pipeline trench excavation and support device. Background Technology

[0002] Pipeline trenches are underground trenches used to lay pipelines, primarily for protecting the pipelines and facilitating maintenance and repair. Pipeline trenches typically consist of a series of interconnected pipes used to transport various media, such as water, gas, and electricity. The design and construction of pipeline trenches require precise planning to ensure the normal operation and safety of the system. Because these trenches have a certain depth, their sidewalls need to be supported during excavation to prevent sidewall collapse and maintain excavation efficiency.

[0003] In response to this, Chinese Patent No. CN215367320U proposes a municipal pipeline trench excavation support device. This utility model can effectively drain water from the soil at the edge of the trench by setting a conduit, avoiding soil collapse caused by high moisture content, which would affect the work of workers. This utility model is reasonably designed, not only simple to operate, but also avoids the trouble caused by soil collapse. During the excavation of pipeline trenches, it is necessary to continue to excavate the already excavated trench area according to its burial depth. However, the above-mentioned technical solutions and existing support devices will block the trench burial area after excavation and support, and continuing to excavate will cause significant construction obstacles. At the same time, the existing support devices are large in size and very inconvenient to transport, thus reducing the convenience of the device. Utility Model Content

[0004] The purpose of this utility model is to provide a support device for excavating pipeline trenches, so as to solve the problems mentioned in the background art. To achieve the above objective, this utility model proposes a support device for excavating pipeline trenches, including two extrusion plates and a support and reinforcement mechanism installed between the two extrusion plates;

[0005] The support and reinforcement mechanism includes a support groove installed between two extrusion plates. Support bars are inserted and connected to both ends of the support groove. A rack is fixedly provided on one side of each of the two support bars. A connecting groove is opened in the inner wall of the support groove. A knob is inserted and connected to the middle position of the top of the support groove. A gear is fixedly connected to one end of the knob through the inner wall of the connecting groove, and the outer wall of the gear meshes with the outer walls of the two racks respectively.

[0006] In one example, limit grooves are provided at both ends of the inner wall of the connecting groove, and limit strips are fixedly provided on both sides of the outer wall of the two support strips, and the inner walls of the four limit strips are respectively interlocked with the inner walls of the four limit grooves.

[0007] In one example, a fixing pin is inserted into the inner wall of the knob, and a threaded hole is provided at the middle position of the bottom of the inner wall of the connecting groove. The outer wall of one end of the fixing pin passes through the inner wall of the gear side and is threadedly connected to the inner wall of the threaded hole.

[0008] In one example, handles are fixedly provided on both sides of the top of the support groove.

[0009] In one example, a limiting groove is provided on one side of each of the two extrusion plates, and a locking block is fixedly provided at one end of each of the two support bars, with the outer walls of the two locking blocks slidably connected to the inner walls of the two limiting grooves respectively.

[0010] In one example, rollers are rotatably connected to both sides of the outer walls of the two card blocks, and the outer walls of the four rollers are respectively rotatably connected to the inner walls at both ends of the two limiting slide grooves. A hanging plate is fixedly provided on one side of the top of the two extrusion plates.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting up a support and reinforcement mechanism, when using construction templates to support the trench sidewalls, the extrusion plate is hung on the wooden board, and the knob is rotated to make the gear mesh with the rack and pinion, which moves the support bar to both ends, thereby applying pressure to the extrusion plate to fully compress the supporting wooden board and prevent the trench sidewalls from collapsing during construction. When further excavation is needed, the gear is rotated in the opposite direction to reduce the pressure of the support and reinforcement mechanism on the extrusion plate. The mechanism can then be moved on the extrusion plate by the rollers, clearing the area that needs to be excavated for further excavation. At the same time, this design is compact and easy to transport, thereby improving the convenience of using the device. Attached Figure Description

[0017] 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.

[0018] Please see Figure 1-4 This utility model provides a technical solution: a pipeline trench excavation support device, comprising two extrusion plates 1 and a support and reinforcement mechanism 2 installed between the two extrusion plates 1;

[0019] The support and reinforcement mechanism 2 includes a support groove 201 installed between two extrusion plates 1. Support bars 202 are inserted and connected to both ends of the support groove 201. A rack 203 is fixedly provided on one side of each of the two support bars 202. A connecting groove 204 is opened on the inner wall of the support groove 201. A knob 207 is inserted and connected to the middle position of the top of the support groove 201. One end of the knob 207 passes through the inner wall of the connecting groove 204 and is fixedly connected to a gear 208. The outer wall of the gear 208 meshes with the outer walls of the two racks 203 respectively.

[0020] In use, wooden planks are used to support the sidewalls of the trench. Then, the fixing pins 209 on the knob 207 are loosened, and the knob 207 is rotated to rotate the gear 208, engaging the rack 203 and pushing the support bars 202 at both ends away from each other until the pressing plates 1 at both ends contact the support planks on the trench sidewalls. The planks are then hung on the wooden planks using the hanging plate 7, and the gear 208 is rotated to press the pressing plates 1 against the wooden planks, thus stably supporting the sidewalls of the trench and achieving the reinforcement function. After support is completed, the fasteners are tightened. The fixed pin 209 is inserted into the threaded hole 210 to fix it, and such support devices are continuously stacked on the trench. After the support is completed, when it is necessary to continue to excavate the various areas, the fixed pin 209 is loosened and the rotating gear 208 is rotated to loosen the pressure on the extrusion plate 1. The support groove 201 is pushed by the handle 3 so that it can slide on the extrusion plate 1 through the locking block 5 and the roller 6 at its upper end, clearing the area that needs to be excavated without causing obstruction and facilitating the excavation of the trench. At the same time, the design is small in size, easy to transport, and improves the convenience of using the device.

[0021] Limiting grooves 205 are provided at both ends of the inner wall of the connecting groove 204, and limiting strips 206 are fixedly provided on both sides of the outer wall of the two support strips 202. The inner walls of the four limiting strips 206 are respectively connected to the inner walls of the four limiting grooves 205, and the limiting strips 206 slide in the limiting grooves 205, making the support strips 202 more stable when adjusting left and right.

[0022] Furthermore, a fixing pin 209 is inserted into the inner wall of the knob 207. A threaded hole 210 is provided at the middle position of the bottom of the inner wall of the connecting groove 204. The outer wall of one end of the fixing pin 209 passes through the inner wall of one side of the gear 208 and is threadedly connected to the inner wall of the threaded hole 210. After the gear 208 meshes with the rack 203 and is adjusted, tightening the fixing pin 209 so that it is inserted into the threaded hole 210 can fix the knob 207 and the gear 208 so that they no longer rotate, thereby fixing the position of the support bar 202.

[0023] Furthermore, handles 3 are fixedly provided on both sides of the top of the support groove 201. The handles 3 facilitate the handling of the device and the operation of the support groove 201 to move between the extrusion plates 1.

[0024] Furthermore, a limiting groove 4 is provided on one side of each of the two extrusion plates 1, and a locking block 5 is fixedly provided at one end of each of the two support bars 202, and the outer wall of the two locking blocks 5 is slidably connected to the inner wall of the two limiting grooves 4 respectively.

[0025] Rollers 6 are rotatably connected to both sides of the outer wall of the two locking blocks 5, and the outer walls of the four rollers 6 are respectively rolled to the inner walls at both ends of the two limiting slide grooves 4. A hanging plate 7 is fixedly provided on one side of the top of the two extrusion plates 1. By sliding the locking blocks 5 and the limiting slide grooves 4, the support and reinforcement mechanism 2 is connected to the extrusion plate 1, and the rollers 6 roll in the limiting slide grooves 4, so that the mechanism can move and adjust smoothly between the extrusion plates 1 when adjusting the position.
