Description

Technical Field

[0001] This utility model relates to the field of positioning tools, specifically an installation and positioning tool for precast drainage blocks. Background Technology

[0002] In slope protection engineering, constructing drainage channels by laying precast drainage blocks is a common practice. This method can effectively remove surface water and groundwater from the slope, improve slope stability, and prevent geological disasters such as landslides and collapses caused by water accumulation.

[0003] Before laying the drainage ditch, the slope foundation needs to be treated to ensure that it is flat and solid, meeting the requirements for ditch laying. Then, according to the design plan, precast blocks can be laid one by one on the slope to form a continuous drainage ditch. During the laying process, attention should be paid to ensuring tight joints between the precast blocks to prevent water leakage.

[0004] In existing technologies, the installation of precast blocks is usually carried out by hoisting equipment to the top of the trench, and then construction workers collect and install the precast blocks. However, in practice and observation, it has been found that this installation method requires more time to adjust the position and angle of the precast blocks, which reduces construction efficiency.

[0005] Therefore, an installation and positioning tool for prefabricated drainage blocks is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: A precast drainage block installation and positioning tool of this utility model includes a vehicle body with four universal wheels installed at the bottom; a box body fixedly connected to the top of the vehicle body; a motor fixedly connected to the top of the box body; a positive and negative lead screw rotatably connected inside the box body; the ends of the positive and negative lead screws penetrate the box body; a belt is sleeved between the motor output end and the ends of the positive and negative lead screws; a slider is symmetrically threaded in the middle of the positive and negative lead screws; a sliding groove is provided on one side of the box body, which slides with the slider; a vertical plate is fixedly connected to the end of the slider; a guide plate is fixedly connected to the top of the vertical plate; the guide plate is inclined and has an arc transition with the vertical plate; through the cooperation of the positive and negative lead screws and the vertical plate, rotating the positive and negative lead screws can adjust the spacing between the vertical plates, thereby limiting the installation of precast drainage blocks of different sizes, facilitating positioning work during drainage ditch construction and installation, and improving the convenience and accuracy of precast drainage blocks during installation.

[0008] Preferably, a groove is provided on the inner side of the upright plate; multiple rotating wheels are rotatably connected to the inner wall of the groove; by setting the rotating wheels, when the drainage precast block moves down along the upright plate, the drainage precast block will come into contact with the rotating wheels, and the rotating wheels will rotate under the action of friction, reducing the sliding friction between the drainage precast block and the upright plate, reducing the resistance encountered by the drainage precast block when moving down, and facilitating the falling and installation operation of the drainage precast block.

[0009] Preferably, the middle of the box body is detachably fixed with a shell; the motor and belt are both located inside the shell; by setting up the shell, since the device is located inside the trench, there is a lot of soil around it and it is a complex construction environment, the shell can enclose and protect the belt and motor, reduce the pollution effect of soil, powder and other impurities in the environment, and extend the service life of the motor and belt.

[0010] Preferably, mesh plates are provided on both sides of the housing; an mounting plate is fixed to the outer wall of the mesh plate; the mounting plate and the housing are connected by bolts; by setting the mesh plate, air exchange between the inside of the housing and the outside can be carried out through the mesh plate, the mesh plate can filter impurities in the airflow, thereby dissipating heat from the motor and reducing the heat accumulated inside the housing. At the same time, by setting the mounting plate, the mesh plate and the mounting plate can be quickly disassembled by removing the bolts, which facilitates the stable filtration work of the mounting plate.

[0011] Preferably, a first elastic cloth is fixedly connected between the pair of sliders; a second elastic cloth is fixedly connected between the slider and the end of the slide groove; through the cooperation of the first elastic cloth and the second elastic cloth, when the slider slides under the transmission action of the positive and negative lead screws, the second elastic cloth will undergo corresponding tensile deformation, while the first elastic cloth will undergo contraction deformation, thereby further sealing the box and ensuring that it will not hinder the sliding of the slider, reducing the situation where external impurities enter the box through the slide groove, and reducing the frequency of maintenance of the positive and negative lead screws.

[0012] Preferably, a connecting rod is fixedly connected to the bottom of the vehicle body; a baffle is fixedly connected to the end of the connecting rod; the baffle has an arc-shaped structure; by setting the baffle, the vehicle body will move with the baffle when it moves. Under the action of the arc-shaped structure of the baffle, the baffle will push away the soil and gravel on the path of the universal wheel, reducing the collision between the universal wheel and these impurities when it moves, and improving the stability of the vehicle body when it moves.

[0013] The advantages of this utility model are:

[0014] 1. The installation and positioning tool for precast drainage blocks described in this utility model, through the cooperation of positive and negative screw rods and vertical plates, allows for adjustment of the spacing between the vertical plates by rotating the positive and negative screw rods, thereby limiting the installation of precast drainage blocks of different sizes, facilitating the positioning work during drainage ditch construction and installation, and improving the convenience and accuracy of precast drainage blocks during installation.

[0015] 2. The installation and positioning tool for precast drainage blocks described in this utility model, by setting a rotating wheel, allows the precast drainage block to come into contact with the rotating wheel as it moves down along the vertical plate. The rotating wheel will then rotate under friction, reducing the sliding friction between the precast drainage block and the vertical plate, reducing the resistance encountered by the precast drainage block when it moves down, and facilitating the installation operation of the precast drainage block.

[0023] 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 scope of protection of the present utility model.

[0024] Specific implementation examples are given below.

[0025] Please see Figures 1 to 5As shown in the figure, an installation and positioning tool for precast drainage blocks according to an embodiment of the present invention includes a vehicle body 1, with four universal wheels installed at the bottom of the vehicle body 1; a box 12 is fixedly connected to the top of the vehicle body 1; a motor 13 is fixedly connected to the top of the box 12; a positive and negative lead screw 14 is rotatably connected inside the box 12; the end of the positive and negative lead screw 14 passes through the box 12; a belt is sleeved between the output end of the motor 13 and the end of the positive and negative lead screw 14; a slider 15 is symmetrically threadedly connected to the middle of the positive and negative lead screw 14; a sliding groove is provided on one side of the box 12, which slides with the slider 15. A vertical plate 16 is fixedly connected to the end of the slider 15; a guide plate 17 is fixedly connected to the top of the vertical plate 16; the guide plate 17 is inclined and has an arc transition with the vertical plate 16; during construction, the device can be moved into the trench, and then the distance between the pair of vertical plates 16 can be adjusted according to the design requirements so that the distance between the vertical plates 16 is equal to the length of the U-shaped drainage precast block. Specifically, the motor 13 is started to drive the belt to rotate the positive and negative screws 14. When the positive and negative screws 14 rotate, the slider 15 slides along the box 12, and the pair of vertical plates 16 move together with the slider 15. To facilitate the relative movement of the devices, the spacing between the upright plates 16 can be quickly adjusted. After adjustment, the precast drainage blocks can be lowered one by one into the trench along the guide channel formed by the pair of upright plates 16. During the process, if the precast drainage blocks deviate, they will come into contact with the guide plate 17. Because the guide plate 17 is inclined, the precast drainage blocks will continue to fall between the upright plates 16 under the guidance of the guide plate 17 until the internal cavity of the upright plates 16 is filled with precast drainage blocks. This ensures that the edges of this batch of precast drainage blocks are aligned under the limiting action of the upright plates 16. Then, the vehicle body 1 can be pulled to move one end. The distance can be such that the end of the upright plate 16 is flush with the precast drainage block located at the end. The above operation can then be repeated until the entire drainage channel is installed, thus achieving the positioning and installation of the precast drainage blocks by the device. It is worth mentioning that a maintenance plate for inspecting the positive and negative screw rods 14 is provided on one side of the box 12. Through the cooperation of the positive and negative screw rods 14 and the upright plate 16, the distance between the upright plates 16 can be adjusted by rotating the positive and negative screw rods 14, so as to limit the installation of precast drainage blocks of different sizes, which facilitates the positioning work during the construction and installation of the drainage channel and improves the convenience and accuracy of the precast drainage blocks during installation.

[0026] Please see Figure 3 and Figure 4 As shown, a groove 2 is provided on the inner side of the upright plate 16; multiple rotating wheels 22 are rotatably connected to the inner wall of the groove 2; by setting the rotating wheels 22, when the drainage precast block moves down along the upright plate 16, the drainage precast block will come into contact with the rotating wheels 22, and the rotating wheels 22 will rotate under the action of friction, reducing the sliding friction between the drainage precast block and the upright plate 16, reducing the resistance encountered by the drainage precast block when moving down, and facilitating the falling and installation operation of the drainage precast block.

[0027] Please see Figure 3 As shown, the housing 3 is detachably fixed to the middle of the box 12; the motor 13 and the belt are both located inside the housing 3; by setting the housing 3, since the device is located inside the trench, there is a lot of soil around it and it is a complex construction environment, the housing 3 can enclose and protect the belt and motor 13, reduce the pollution effect of soil, powder and other impurities in the environment, and extend the service life of the motor 13 and the belt.

[0028] Please see Figure 3 and Figure 5 As shown, mesh plates 4 are provided on both sides of the housing 3; an mounting plate 42 is fixed to the outer wall of the mesh plate 4; the mounting plate 42 and the housing 3 are connected by bolts; by setting the mesh plate 4, the interior of the housing 3 can exchange air with the outside through the mesh plate 4, the mesh plate 4 can filter impurities in the airflow, thereby dissipating heat from the motor 13 and reducing the heat accumulated inside the housing 3. At the same time, by setting the mounting plate 42, the mesh plate 4 and the mounting plate 42 can be quickly disassembled by removing the bolts, which facilitates the stable filtering operation of the mounting plate 42.

[0029] Please see Figure 3 and Figure 4 As shown, a first elastic cloth 5 is fixed between a pair of sliders 15; a second elastic cloth 52 is fixed between the slider 15 and the end of the slide groove; through the cooperation of the first elastic cloth 5 and the second elastic cloth 52, when the slider 15 slides under the transmission action of the positive and negative lead screws 14, the second elastic cloth 52 will undergo corresponding tensile deformation, while the first elastic cloth 5 will undergo contraction deformation, thereby further sealing the box 12 and ensuring that it will not hinder the sliding of the slider 15, reducing the situation where external impurities enter the interior of the box 12 through the slide groove, and reducing the frequency of maintenance of the positive and negative lead screws 14.

[0030] Please see Figure 2 As shown, a connecting rod 6 is fixedly connected to the bottom of the vehicle body 1; a baffle 62 is fixedly connected to the end of the connecting rod 6; the baffle 62 has an arc-shaped structure; by setting the baffle 62, the vehicle body 1 will move along with the baffle 62 when it moves. Under the action of the arc-shaped structure of the baffle 62, the baffle 62 will push away the soil and gravel on the path of the universal wheel, reduce the collision between the universal wheel and these impurities when it moves, and improve the stability of the vehicle body 1 when it moves.

[0031] Working principle: The device is moved into the trench. The distance between the pair of upright plates 16 can then be adjusted according to design requirements, ensuring the distance is equal to the length of the U-shaped drainage precast block. Specifically, the motor 13 is started, causing the belt to drive the positive and negative lead screws 14 to rotate. As the lead screws 14 rotate, the slider 15 slides along the box 12, and the pair of upright plates 16 move together with the slider 15, moving towards each other. This allows for rapid adjustment of the distance between the upright plates 16. After adjustment, the drainage precast blocks are lowered one by one into the trench along the guide channel formed by the pair of upright plates 16. During this process, if the drainage precast block deviates, it will contact the guide plate 17. The guide plate 17 is inclined, allowing the precast drainage blocks to continue falling between the vertical plates 16 under its guidance until the internal cavity of the vertical plates 16 is filled with the precast drainage blocks. This ensures that the edges of this batch of precast drainage blocks are aligned under the limiting effect of the vertical plates 16. Then, the vehicle body 1 can be pulled to move it a certain distance, specifically until the end of the vertical plate 16 is flush with the precast drainage block located at that end. This process can be repeated until the entire drainage channel is installed, achieving the positioning and installation of the precast drainage blocks. It is worth noting that a maintenance plate for inspecting the positive and negative lead screws 14 is provided on one side of the box body 12. By setting the rotating wheel 22, the precast drainage blocks are positioned along the vertical plates... When the vertical plate 16 moves downward, the precast drainage block will come into contact with the rotating wheel 22, which will rotate under friction, reducing the sliding friction between the precast drainage block and the vertical plate 16, reducing the resistance encountered by the precast drainage block when moving downward, and facilitating the installation of the precast drainage block. By setting up the shell 3, since the device is located inside the trench, there is a lot of soil around it and it is a complex construction environment. The shell 3 can enclose and protect the belt and motor 13, reducing the pollution effect of soil, powder and other impurities in the environment, and extending the service life of the motor 13 and the belt. By setting up the mesh plate 4, the inside of the shell 3 can exchange air with the outside through the mesh plate 4, and the mesh plate 4 can filter impurities in the airflow. Filtration is performed, which dissipates heat from the motor 13 and reduces the heat accumulated inside the housing 3. At the same time, by setting up the mounting plate 42, the mesh plate 4 and the mounting plate 42 can be quickly disassembled by removing the bolts, which facilitates the stable filtration operation of the mounting plate 42. Through the cooperation of the first elastic cloth 5 and the second elastic cloth 52, when the slider 15 slides under the transmission action of the positive and negative screws 14, the second elastic cloth 52 will undergo corresponding stretching deformation, while the first elastic cloth 5 will undergo contraction deformation. This further seals the box 12 and ensures that it does not hinder the sliding of the slider 15, reduces the possibility of external impurities entering the box 12 through the slide groove, and reduces the frequency of maintenance of the positive and negative screws 14.By setting up baffle 62, the vehicle body 1 moves along with baffle 62 during movement. The arc-shaped structure of baffle 62 pushes away clods of soil and gravel along the path of the omnidirectional wheels, reducing collisions between the omnidirectional wheels and these impurities and improving the stability of the vehicle body 1 during movement.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
