Description

Technical Field

[0001] The utility model relates to the technical field of municipal engineering, in particular to a municipal engineering trench excavation auxiliary device. Background Art

[0002] In municipal engineering, trench excavation is the foundation for laying pipelines (such as water supply and drainage pipelines, gas pipelines, communication pipelines, etc.), cables and other infrastructure. High-quality trench excavation can ensure the accuracy, stability and safety of subsequent pipeline installation, which is crucial to the quality and service life of the entire municipal engineering.

[0003] The traditional municipal engineering trench excavation auxiliary device still has the following shortcomings: 1. The excavation method of the traditional municipal engineering trench excavation auxiliary device is inefficient and cannot meet the construction needs of large-scale municipal engineering; 2. Different municipal engineering construction sites face various complex geological conditions, such as hard rock layers, highly viscous soils, and strata containing a large amount of sand and gravel. These different geological conditions put forward diverse requirements for excavation tools and methods. The single excavation head of the traditional municipal engineering trench excavation auxiliary device is often difficult to adapt. Therefore, we proposed a municipal engineering trench excavation auxiliary device. Utility Model Content

[0004] The main purpose of the utility model is to provide a municipal engineering trench excavation auxiliary device, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A municipal engineering trench excavation auxiliary device comprises a bottom block, wherein the bottom blocks are provided with four, the upper ends of the four bottom blocks are fixedly connected to support rods, the upper ends of the four support rods are commonly fixedly connected to a top plate, the four bottom blocks are fixedly connected to connecting plates between each other, the middle parts of the upper ends of the two connecting plates are fixedly connected to a stabilizing rod, the outer side surfaces of the four bottom blocks are fixedly connected to side plates, the upper front parts and upper rear parts of the two side plates are interspersed with fixed components, a control device is interspersed and fixedly installed on the middle part of the upper end of the top plate, a rotating motor is fixedly installed on the lower end of the control device, a flange is fixedly installed on the output end of the rotating motor, a striker is fixedly connected to the lower end of the flange, an auxiliary component is threadedly connected to the lower end of the striker, and locking universal wheels are fixedly installed on the lower ends of the four bottom blocks;

[0007] The auxiliary component includes a striker, a striker head is fixedly connected to the lower end of the striker, a mounting groove is opened at the upper end of the striker, and an internal threaded tube is fixedly connected to the middle of the lower inner wall surface of the mounting groove.

[0008] Preferably, the inner wall surface of the internally threaded tube and the lower portion of the outer surface of the striker are both engraved with thread grooves, and the inner wall surface of the internally threaded tube is threadedly connected to the outer surface of the striker through the two thread grooves.

[0009] By adopting the above technical solution: when the auxiliary component needs to be installed, it is only necessary to align the internal threaded tube with the outer surface of the striker rod, and then by rotating the auxiliary component and utilizing the guiding effect of the thread, the two can be easily connected together. This installation method does not require complicated tools and professional skills. The operator can quickly complete the installation process, thereby improving work efficiency.

[0010] Preferably, the fixing assembly includes a fixing rod, the upper end of the fixing rod is fixedly connected to a rod head, the lower end of the fixing rod is fixedly connected to a screw rod, and the lower end of the screw rod is fixedly connected to a drill bit.

[0011] By adopting the above technical solution: a drill bit is fixedly connected to the lower end of the screw. When the fixing operation is performed, the fixing rod is driven by rotating the rod head, thereby rotating the screw, and the drill bit can drill into the ground. This fixing method deep into the ground can provide stronger grip than the fixing method that relies solely on flat contact, making the entire device more stable during the trench excavation process and not easy to move due to vibration and external force generated by excavation.

[0012] Preferably, movable grooves are formed at the front and rear upper ends of the two side plates, and the outer surface of the screw is threadedly connected to the inner wall surface of the corresponding movable groove.

[0013] By adopting the above technical solution: since the screw is threadedly connected to the movable groove on the side plate, the screw can move up and down in the movable groove by rotating the fixing rod (which in turn drives the screw to rotate). This allows the fixing component to flexibly adjust the depth of drilling into the ground according to different trench excavation depths and ground conditions, thereby achieving the best fixing effect.

[0014] Preferably, the control device includes a cylinder, the output end of the cylinder is fixedly mounted with a mounting plate, the left and right outer surfaces of the mounting plate are fixedly connected with fixing blocks, the outer sides of the two fixing blocks are fixedly connected with connecting rings, the lower end of the cylinder is fixedly connected to the upper end of the top plate, and the output end of the cylinder passes through the upper end of the top plate and extends to the lower end of the top plate.

[0015] By adopting the above technical solution: using a cylinder as the power source, the output end of the cylinder drives the mounting plate to move linearly. Due to the movement characteristics of the cylinder, it can provide very precise vertical displacement control. In the trench excavation of municipal engineering, this is crucial for accurately controlling the working position of the excavation auxiliary device, and can ensure that the excavation depth and accuracy meet the engineering requirements.

[0016] Preferably, the inner wall surfaces of the two connecting rings are respectively slidably connected to the outer surfaces of the corresponding two stabilizing rods, and the lower end of the mounting plate is fixedly connected to the upper end of the rotating motor.

[0017] By adopting the above technical solution: the inner wall surfaces of the two connecting rings are respectively slidably connected to the outer surfaces of the corresponding two stabilizing rods, and the stabilizing rods provide precise guidance for the connecting rings. When the cylinder pushes the mounting plate to move, the connecting rings slide up and down along the stabilizing rods, ensuring that the mounting plate and the rotating motor connected thereto can only move in the vertical direction.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. In the present invention, the auxiliary component can be easily replaced with different types of impact heads through the threaded connection between the impact rod and the internal threaded tube. The appropriate impact head can be selected according to different soil conditions and excavation requirements, thereby improving the excavation efficiency. For example, a sharper impact head can be used in harder soil, and a wider impact head can be used in softer soil to achieve the best excavation effect.

[0020] 2. In the utility model, the control device drives the mounting plate to move through the cylinder, thereby realizing the up and down movement of the rotating motor and the ram rod, which is simple and convenient to operate. Moreover, this design enables the operator to flexibly adjust the position of the ram head according to the requirements of the excavation depth, thereby improving the adaptability and operational convenience of the device. The rotating motor drives the ram rod and the auxiliary components to rotate through the flange, and the ram head strikes the ground. This mechanical drive method can quickly and effectively break the soil and improve the efficiency of trench excavation. BRIEF DESCRIPTION OF THE DRAWINGS
