Description

Technical Field

[0001] This utility model relates to the field of line-laying equipment technology, and in particular to a precision line-laying equipment for channel excavation in water conservancy projects. Background Technology

[0002] Before the excavation of water conservancy projects, surveying and setting out are required. Setting out involves drawing lines on the ground with lime powder. The purpose of lime powder setting out is to facilitate the work of workers and to ensure that construction is carried out strictly according to the design drawings. However, in the current water conservancy project construction process, construction workers usually move the bucket containing lime powder and use their hands to grab the lime powder to set out the lines. This method of operation consumes a lot of manpower, is labor-intensive, and has low accuracy.

[0003] For example, a line-laying device for water conservancy projects disclosed in Chinese patent literature (announcement number: CN219908492U) is operated by pulling a ring, which moves a rope and causes a baffle to move along the inside of a C-shaped frame. At this time, the spring is compressed and the baffle reaches the designated position. The top surface of the baffle completely leaves the bottom of the discharge port, and lime powder falls from the discharge port. At the same time, the personnel push the device along the designated route to complete the line-laying operation.

[0004] However, during the laying process, to avoid excessive spillage and waste of lime powder, the discharge port diameter is usually set to be small. Lime powder itself has fine particles and its flowability is greatly affected by the environment. However, the lime powder in the tank becomes denser due to vibration during the movement of the device. The gaps between the small-diameter lime powder particles are squeezed and filled, forming a dense accumulation structure. This can easily lead to poor material discharge during laying, which not only affects the laying efficiency but also easily causes laying interruptions, affecting the accuracy of subsequent channel excavation and construction. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies. Currently, when lime powder is laid out, it is easy to cause poor material discharge, which not only affects the laying efficiency but also affects the accuracy of subsequent channel excavation after the laying is interrupted.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A precision line-laying device for channel excavation in water conservancy projects includes a mobile frame, a storage tank fixedly sleeved on the inner wall of the mobile frame, and an auxiliary line-laying mechanism provided at the lower end of the storage tank.

[0008] The auxiliary wire feeding mechanism includes a discharge pipe, the upper end of which is fixedly connected to the lower end of the storage tank. A servo motor is fixedly installed on the upper end of the storage tank. The output shaft of the servo motor is fixedly installed with a rotating shaft through a coupling. One end of the rotating shaft extends into the inside of the discharge pipe. A spiral blade is fixedly sleeved on the outside of the rotating shaft. The outer side of the spiral blade contacts the inner wall of the discharge pipe.

[0009] A leak-proof mechanism is provided below the mobile frame.

[0010] Preferably, the rotating shaft is externally fixedly connected to a stirring rod arranged in a ring array, and the upper end of the storage tank is fixedly connected to a feeding hopper.

[0011] Preferably, the leak-proof mechanism includes a support frame, the upper end of which is fixedly connected to the lower end of the movable frame, and the inner wall of the support frame is slidably fitted with symmetrically distributed guide rods.

[0012] Preferably, a movable baffle is fixedly connected to one end of each of the two guide rods, the upper end of the movable baffle contacts the lower end of the discharge pipe, and a return spring is movably sleeved on the outside of the guide rod.

[0013] Preferably, one end of each of the two return springs is fixedly connected to one side of the movable baffle, and the other end of each of the two return springs is fixedly connected to one side of the support frame, wherein a guide hole is provided on one side of the support frame.

[0014] Preferably, a limiting block is fixedly connected to one side of the movable frame, and a pull rope is fixedly connected to one side of the movable baffle. One end of the pull rope passes through the guide hole and the limiting block in sequence and is fixedly connected to a pull ring. The outside of the pull ring contacts the upper end of the limiting block.

[0015] Preferably, a push handle is fixedly connected to the upper end of the movable frame, and a hook is fixedly connected to the inner top wall of the push handle.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] In this invention, an auxiliary feeding mechanism is used to drive the rotating shaft to rotate via a servo motor. The stirring rod continuously stirs the lime powder in the storage tank, breaking up the densely packed lime powder. The spiral blades push the lime powder at a constant speed to the outlet of the discharge pipe through the spiral propulsion force. This not only avoids clogging by small-diameter lime powder and ensures continuous and stable discharge, but also allows for precise control of the amount of lime powder sprinkled during feeding by controlling the rotation speed of the spiral blades. This improves feeding efficiency and the accuracy of subsequent channel excavation.

[0018] The anti-leakage mechanism uses a movable baffle to block the bottom of the discharge pipe, preventing lime powder from leaking out in areas where line laying is not required. When laying the line, the pull ring is hooked into the hook, and the hook's support force keeps the movable baffle open without continuous force, freeing up the workers' hands. When closing the discharge, the pull ring is removed, and the spring force of the return spring causes the movable baffle to return to its original position, tightly fitting the bottom of the discharge pipe and automatically sealing the discharge port.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0029] Example

[0030] like Figure 1-5 As shown, this utility model provides a technical solution: a precision line-laying device for water conservancy engineering channel excavation, including a mobile frame 1, which serves as a basic carrier and is equipped with support legs and moving wheels below. It also integrates an auxiliary line-laying mechanism and a material leakage prevention mechanism to achieve stable, accurate, and convenient line laying of lime powder, which is suitable for the requirements of line-laying accuracy and efficiency in water conservancy channel excavation construction.

[0031] The storage tank 2 is fixedly sleeved on the inner wall of the mobile frame 1 for storing lime powder. A servo motor 31 is installed on the upper end of the storage tank 2, and its output shaft is connected to the rotating shaft 32 through a coupling. When the servo motor 31 starts, the output shaft rotates and drives the rotating shaft 32 to rotate synchronously.

[0032] A stirring rod 34 arranged in a ring array is fixedly connected to the outside of the rotating shaft 32. As the rotating shaft 32 rotates, the stirring rod 34 makes a circular motion inside the storage tank 2, continuously stirring the lime powder inside the storage tank 2.

[0033] During water conservancy construction, lime powder is prone to becoming dense and accumulating due to equipment movement, vibration, or static placement. The stirring rod 34 can disrupt this accumulation state, prevent lime powder from "bridging" and clumping, and ensure good flowability of lime powder.

[0034] The rotating shaft 32 extends into the discharge pipe 3, and the spiral blade 33 fixedly sleeved on its outside contacts the inner wall of the discharge pipe 3. When the rotating shaft 32 rotates, the spiral blade 33 pushes the lime powder in the storage tank 2 to the outlet of the discharge pipe 3 at a uniform speed through the spiral propulsion principle. Compared with the traditional manual grabbing or simple discharge method, the spiral blade 33 can avoid small-diameter lime powder from clogging the discharge pipe 3 and achieve continuous and stable discharge.

[0035] Meanwhile, by controlling the speed of the servo motor 31, the speed at which the spiral blade 33 pushes the lime powder can be precisely adjusted, thereby accurately controlling the amount of lime powder sprinkled during the laying process, improving the uniformity of the laying process and the accuracy of subsequent channel excavation. The feeding hopper 35 connected to the upper end of the storage tank 2 facilitates the replenishment of lime powder. The feeding hopper 35 can be covered with a dust cover to prevent debris from entering during construction and affecting the laying process.

[0036] In the anti-leakage mechanism below the mobile frame 1, the support frame 4 is fixedly connected to the lower end of the mobile frame 1, and the inner wall of the support frame 4 is slidably fitted with symmetrically distributed guide rods 41. One end of the guide rod 41 is connected to the moving baffle 42. In the initial state, the upper end of the moving baffle 42 contacts the lower end of the discharge pipe 3, blocking the lower part of the discharge pipe 3 to prevent lime powder from leaking out when it is not necessary to lay the line, keeping the construction site clean and reducing lime powder waste.

[0037] The guide rod 41 is externally movably sleeved with a reset spring 43. One end of the spring is fixed to one side of the movable baffle 42, and the other end is fixed to one side of the support frame 4. The support frame 4 has a guide hole 44. The pull rope 46 connected to one side of the movable baffle 42 passes through the guide hole 44 and the limit block 45 in sequence and then connects to the pull ring 47.

[0038] During the line laying operation, the construction worker pulls the pull ring 47, and the pull rope 46 pulls the moving baffle 42 to slide along the guide rod 41, compressing the reset spring 43, so that the moving baffle 42 is disengaged from the lower end of the discharge pipe 3, and the discharge pipe 3 is opened. Then, the pull ring 47 is hooked into the hook 49 on the inner top wall of the push handle 48. The supporting force of the hook 49 is used to maintain the moving baffle 42 in the open state. The construction worker does not need to continuously pull the pull ring 47, freeing his hands and allowing him to focus on pushing the equipment to move along the designed route, improving the convenience of operation and the efficiency of line laying.

[0039] When the line is finished or when a pause is needed, remove the pull ring 47 on the hook 49. The elastic force of the return spring 43 causes the moving baffle 42 to return to its original position along the guide rod 41, tightly fitting the lower end of the discharge pipe 3, automatically sealing the discharge port, effectively preventing lime powder leakage. The pull ring 47 will also move above the limit block 45, making it easy to quickly find the position of the pull ring 47 in the next operation.

[0040] The push handle 48 fixed at the upper end of the mobile frame 1 is ergonomically designed, making it convenient for construction personnel to hold and push the equipment. During the process of pushing the equipment, the auxiliary line-laying mechanism stabilizes the material discharge and the anti-leakage mechanism precisely controls the material, allowing the equipment to move at a uniform speed along the designed route and form continuous and clear lime powder marks on the ground. This meets the requirements of the line-laying accuracy for water conservancy channel excavation and provides an accurate construction basis for subsequent channel excavation.

[0041] The working process of this utility model:

[0042] Step 1: Move the equipment to the construction area, add lime powder through the feeding hopper 35, and cover the top of the feeding hopper 35 with a dust cover. The construction worker holds the push handle 48 and then pulls the pull ring 47. The pull ring 47 pulls the moving baffle 42 through the pull rope 46 to compress the return spring 43, thereby causing the moving baffle 42 to disengage from the lower end of the discharge pipe 3. At this time, the discharge pipe 3 opens. Then, hook the pull ring 47 into the hook 49. Use the supporting force of the hook 49 to maintain the baffle opening. No continuous force is required, freeing the hands to focus on pushing the equipment.

[0043] Step 2: Start the servo motor 31. The rotating shaft 32 drives the stirring rod 34 and the spiral blade 33 to rotate. The stirring rod 34 stirs to prevent blockage, and the spiral blade 33 continuously feeds the material. The lime powder is discharged evenly, pushing the moving frame 1 to move at a constant speed along the designed route. A continuous and clear mark is formed on the ground. After the line is laid out, turn off the servo motor 31, remove the pull ring 47 on the hook 49, and the reset spring 43 elastically resets and moves the baffle 42 back to its original position to close the lower end of the discharge pipe 3 through the cooperation of the guide rod 41. The pull ring 47 moves to the top of the limit block 45.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
