Description

Technical Field

[0001] This utility model relates to the field of pipeline construction, and in particular to a pipeline lowering device for pipeline construction. Background Technology

[0002] Pipeline network projects include power supply pipelines, rainwater pipelines, sewage pipelines, water supply pipelines, fire protection pipelines, gas pipelines, communication pipelines, and intelligent pipelines for residential communities. Currently, during pipeline network construction, cranes are mainly used to lower the pipelines into the pre-excavated pipeline trenches.

[0003] The existing method of lowering pipelines using a crane is convenient in some large areas, but it can cause problems in smaller areas where the crane cannot enter, affecting the pipeline lowering construction. Based on this, we propose an improved pipeline lowering device for pipeline construction. Summary of the Invention

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a pipeline lowering device for pipeline construction.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a pipeline lowering device for pipeline network construction, comprising a crane, wherein a winding shaft is rotatably connected to both sides of the top frame of the crane, and winding wheels are fixedly connected to the outer walls of the front and rear ends of the two winding shafts, and lifting ropes are sleeved on the outer walls of the four winding wheels, and the other ends of the four lifting ropes are respectively connected to a first hanger and a second hanger, wherein the first hanger and the second hanger each include a first hanging plate and a second hanging plate, and guide plates are fixedly connected to opposite sides of the first hanging plate and the second hanging plate, respectively, an electric cylinder is fixedly connected inside the first hanging plate, and the output end of the electric cylinder is fixedly connected to the outer wall of the second hanging plate, and a double-acting screw rod is rotatably connected inside the first hanging plate and the second hanging plate, respectively, a slider is threadedly connected to the front and rear outer walls of the first double-acting screw rod, and a slider is threadedly connected to the front and rear outer walls of the second double-acting screw rod, and a support block is fixedly connected to the upper ends of the two sliders, and a support block is fixedly connected to the upper ends of the two sliders.

[0006] With the above technical solution, the device can be effectively used in some small areas. By controlling the winding shaft with a synchronous motor to drive the winding wheel to rotate, the first and second lifting frames can be raised and lowered by the hoisting rope, which facilitates the hoisting of pipelines for lowering construction.

[0007] As a further description of the above technical solution:

[0008] Both the first and second hangers are located below the top frame of the crane. Lifting rings are fixedly connected to the front and rear outer walls of the first and second hanging plates, and the lifting ropes are fixedly connected to the lifting rings.

[0009] With the above technical solution, the upper end of the hoisting rope is fixedly connected to the outer wall of the winding wheel. The hoisting rope is moved by rotating the winding wheel, which facilitates the lifting and lowering of the first and second hoisting frames.

[0010] As a further description of the above technical solution:

[0011] The top frame of the crane is fixedly connected to a synchronous motor. There are two synchronous motors in total, and the output ends of the two synchronous motors are respectively fixedly connected to the front ends of two winding shafts.

[0012] Through the above technical solution, two synchronous motors can synchronously control the rotation of two winding shafts, making it convenient to simultaneously wind up and unwind multiple ropes.

[0013] As a further description of the above technical solution:

[0014] The first guide plate is slidably sleeved inside the body of the second hanging plate, and the second guide plate is slidably sleeved inside the body of the first hanging plate.

[0015] The above technical solution guides the relative movement of the first and second hanging plates through the first and second guide plates, while also serving as an auxiliary load for the electric cylinder.

[0016] As a further description of the above technical solution:

[0017] The rear end of the first bidirectional lead screw passes through the first hanging plate and is fixedly connected to the first handwheel; the rear end of the second bidirectional lead screw passes through the second hanging plate and is fixedly connected to the second handwheel.

[0018] With the above technical solution, rotating handwheel one can drive the double-acting lead screw one to rotate, thereby controlling the two sliders one to drive the support block one to move relative to each other. Rotating handwheel two can drive the double-acting lead screw two to rotate, thereby controlling the two sliders two to drive the support block two to move relative to each other.

[0019] As a further description of the above technical solution:

[0020] The upper end of the second hanging plate is rotatably and fixedly connected to a drive screw and a slide rod near the front and rear positions, respectively. A push plate is threadedly connected to the outer wall of the drive screw, and the other end of the push plate is slidably sleeved on the outer wall of the slide rod.

[0021] With the above technical solution, rotating the drive screw can drive the push plate to move, which makes it easy to push the pipe off the second hanging plate and make the end of the pipe close to the first hanging plate land in advance, so as to facilitate the unloading of the pipe.

[0022] This utility model has the following beneficial effects:

[0023] 1. Compared with the existing technology, this pipeline lowering device for pipeline construction, by setting up a crane, a winding shaft, a winding wheel, a lifting rope, a first hanger and a second hanger structure in coordination, makes the device effective for use in some small areas. By controlling the winding shaft with a synchronous motor to drive the winding wheel to rotate, the first hanger and the second hanger can be raised and lowered by the lifting rope, which facilitates the lifting of the pipeline for lowering construction.

[0024] 2. Compared with existing technologies, this pipeline lowering device for pipeline network construction utilizes a structure consisting of a guide plate 1, a guide plate 2, an electric cylinder, a double-acting screw 1, a double-acting screw 2, a slider 1, a slider 2, a support block 1, and a support block 2, all working in concert. The electric cylinder, limited by the guide plates 1 and 2, controls the relative movement of the first and second hangers, allowing adjustment based on pipeline length. Screw 1 and double-acting screw 2 drive slider 1 and slider 2 respectively, thereby controlling the relative movement of the two support blocks 1 and 2 to adjust the width according to the pipe diameter. This enables the first and second hangers to be suitable for lifting pipelines of various sizes. Furthermore, the drive screw and limiting plate structure on the second hanger allows the drive screw to move the limiting plate during pipeline lowering, pushing one end of the pipeline to the ground first. Then, a moving crane is used to stably lower the pipeline. Attached Figure Description

[0031] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0032] Reference Figure 1-4 This utility model provides a pipe lowering device for pipeline construction: It includes a crane 1, with a winding shaft 2 rotatably connected to both sides of the top frame of the crane 1. Winding wheels 3 are fixedly connected to the outer walls of the front and rear ends of the two winding shafts 2. Lifting ropes 4 are sleeved on the outer walls of the four winding wheels 3. The other ends of the four lifting ropes 4 are respectively connected to a first hanger 5 and a second hanger 6. Both the first hanger 5 and the second hanger 6 include a first hanging plate 501 and a second hanging plate 601. Guide plates 502 and 602 are fixedly connected to opposite sides of the first hanging plate 501 and the second hanging plate 601, respectively. An electric cylinder 503 is fixedly connected inside the first hanging plate 501. The output end of the electric cylinder 503 is fixedly connected to the outer wall of the second hanging plate 601. The action of the electric cylinder 503 can control the first hanging plate 501. 501 and 601 move relative to each other, allowing for easy adjustment according to the pipe length. A double-acting screw 504 and a double-acting screw 603 are rotatably connected inside 501 and 603 respectively. Slider 505 is threaded onto the front and rear outer walls of double-acting screw 504, and slider 604 is threaded onto the front and rear outer walls of double-acting screw 603. Support blocks 506 and 605 are fixedly connected to the upper ends of both sliders 505 and 604. Rotating double-acting screw 504 moves slider 505, which in turn moves support block 506; rotating double-acting screw 603 moves slider 604, which in turn moves support block 605.

[0033] Through the above technical solution, the device can be effectively used in some small areas. By controlling the winding shaft 2 to drive the winding wheel 3 to rotate through the synchronous motor 7, the first lifting frame 5 and the second lifting frame 6 can be wound up and down through the lifting rope 4, which facilitates the hoisting of pipelines for lowering construction.

[0034] The first gantry 5 and the second gantry 6 are both located below the top frame of the crane 1. Lifting rings are fixedly connected to the front and rear outer walls of the first gantry 501 and the second gantry 601. The lifting rope 4 is fixedly connected to the lifting rings. The upper end of the lifting rope 4 is fixedly connected to the outer wall of the winding wheel 3. The lifting rope 4 is moved by rotating the winding wheel 3, which facilitates the lifting and lowering of the first gantry 5 and the second gantry 6.

[0035] A synchronous motor 7 is fixedly connected to the front end of the top frame of the crane 1. There are two synchronous motors 7 in total. The two synchronous motors 7 are controlled by a controller. The output ends of the two synchronous motors 7 are fixedly connected to the front ends of the two winding shafts 2 respectively. The two synchronous motors 7 can synchronously control the rotation of the two winding shafts 2, which is convenient for simultaneously winding and unwinding multiple lifting ropes 4.

[0036] Guide plate 502 is slidably sleeved inside the body of hanging plate 601. Guide plate 602 guides the relative movement of hanging plate 501 and hanging plate 601 through guide plate 502 and guide plate 602, and at the same time plays the role of assisting the load of electric cylinder 503.

[0037] The rear end of the double-acting screw 504 passes through the hanging plate 501 and is fixedly connected to a handwheel 1. The rear end of the double-acting screw 603 passes through the hanging plate 601 and is fixedly connected to a handwheel 2. Rotating the handwheel 1 will drive the double-acting screw 504 to rotate, thereby controlling the two sliders 505 to drive the support block 506 to move relative to each other. Rotating the handwheel 2 will drive the double-acting screw 603 to rotate, thereby controlling the two sliders 604 to drive the support block 605 to move relative to each other.

[0038] The upper end of the second hanging plate 601 is rotatably and fixedly connected to a drive screw 606 and a slide rod near the front and rear positions, respectively. A push plate 607 is threadedly connected to the outer wall of the drive screw 606. The other end of the push plate 607 is slidably sleeved on the outer wall of the slide rod. Rotating the drive screw 606 can drive the push plate 607 to move, which makes it easy to push the pipe off the second hanging plate 601 and make one end of the pipe close to the first hanging plate 501 land in advance, so as to facilitate the unloading of the pipe.

[0039] Working principle: In use, firstly, rotating the drive screw 606 moves the push plate 607 to the end of the second hanging plate 601 away from the first hanging plate 501. Then, according to the pipe length, the electric cylinder 503 adjusts the distance between the first hanging plate 501 and the second hanging plate 601. Next, rotating the double-acting screw 504 controls the two sliders 505 to move the two support blocks 506 relative to each other. Then, rotating the double-acting screw 603 controls the two sliders 604 to move the two support blocks 605 relative to each other, so that the pipe can be placed on the two support blocks 506 and the two support blocks 605. Then, the pipe is transported to the desired location by the crane 1. To lower the pipe to the desired position, the synchronous motor 7 controls the rotation of the winding shaft 2, which in turn rotates the winding wheel 3 to lower the hoisting rope 4. This controls the hoisting plates 501 and 601 to descend to the appropriate height. For longer pipes, the electric cylinder 503 can retract to bring the hoisting plate 501 closer to the hoisting plate 601, and then, under the action of the push plate 607, one end of it will touch the ground. Then, by moving the crane 1, the pipe can be lowered stably. For shorter pipes, the drive screw 606 can be rotated to move the push plate 607, which will push the pipe so that one end touches the ground first. Then, the pipe can be lowered in the same way.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
