Description

Technical Field

[0001] This utility model relates to the field of pipeline laying technology, and in particular to an auxiliary device for laying municipal heating pipelines. Background Technology

[0002] As a core component of urban centralized heating systems, municipal heating pipelines play a crucial role in delivering and distributing heating media to heat users. The quality of their installation directly impacts the stability and safety of urban heating. During pipeline laying, multiple short pipe sections must be welded or flanged together to form a long pipe that meets the required length. When connecting adjacent pipes, precise adjustments to their left-right, up-down, front-back positions and tilt angles are necessary to ensure alignment of the connecting ports and guarantee a tight seal.

[0003] Traditional pipeline connection methods rely heavily on external cranes for hoisting and adjustment, but this approach has significant drawbacks: the large range of motion of the crane makes fine adjustments difficult; furthermore, the crane operator cannot directly observe the details of the pipeline connection and must rely on ground personnel for guidance, which can easily lead to insufficient connection accuracy due to information transmission errors. This not only prolongs the construction period but may also leave potential leakage hazards. Therefore, various pipeline laying auxiliary devices are gradually being applied to construction scenarios.

[0004] A search revealed that patent number CN222977581U discloses an auxiliary device for laying municipal heating pipelines. This device uses a longitudinal trolley (including a U-shaped longitudinal trolley frame and a longitudinal roller assembly) and a transverse trolley (including a transverse trolley frame and a transverse gear assembly), along with a fixed arm, a slidingly connected adjusting arm, and a clamping jaw that can close in opposite directions. The device utilizes a telescopic cylinder to drive the adjusting arm to rise and fall and the clamping jaw to hold the pipeline, thereby achieving adjustment of the pipeline's left-right, front-back, and up-down positions, as well as fine-tuning of the tilt angle. This solves, to some extent, the problem of low docking accuracy of traditional cranes. However, when applied in actual municipal construction environments, this device still has the following shortcomings: the roller group walking mechanism used by the longitudinal trolley is prone to slipping or getting stuck in the soil, gravel and uneven ground in the foundation pit, resulting in poor terrain adaptability. In addition, the device lacks a stable support structure, and it is prone to shaking due to uneven ground during construction, which in turn affects the accuracy of pipe connection. The device control relies on manual close-range operation. The limited construction space in the foundation pit not only leads to low operation convenience, but also poses a safety hazard to the operators. The gripper has no circumferential adjustment structure. When there is circumferential misalignment at the pipe connection port, the position and angle of the longitudinal and transverse trolleys need to be readjusted to correct the angle, which is cumbersome and has low connection efficiency.

[0005] Therefore, there is an urgent need for a municipal heating pipeline laying auxiliary device that is highly adaptable to terrain, provides stable support, is easy to operate, and allows for flexible connection, in order to overcome the shortcomings of existing technologies and further improve the efficiency and quality of pipeline laying. Utility Model Content

[0006] The purpose of this utility model is to provide an auxiliary device for laying municipal heating pipelines to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides an auxiliary device for laying municipal heating pipelines, including a longitudinal trolley, on which a transverse trolley is mounted. The transverse trolley's running direction is perpendicular to that of the longitudinal trolley. The transverse trolley includes a transverse frame and a transverse drive mechanism. At least one fixed arm is fixedly connected to the transverse frame, and an adjusting arm is slidably connected to the fixed arm below it. A clamping jaw that can close in opposite directions is installed at the lower end of the adjusting arm. The longitudinal trolley includes a longitudinal frame and tracked walking mechanisms arranged on the left and right sides of the longitudinal frame. Hydraulic outriggers are hinged at the four corners of the bottom of the longitudinal frame. A control box is installed on the transverse frame, integrating a controller, a hydraulic pump station, and a battery. The device is equipped with a wireless remote controller that communicates with the controller. The clamping jaw is connected to the lower end of the adjusting arm via a rotation mechanism.

[0008] Preferably, the lateral drive mechanism is a lateral gear set, and a rack that meshes with the lateral gear set is fixedly installed on the upper part of the longitudinal frame. A sealed protective cover is provided outside the lateral gear set.

[0009] Preferably, the rotary mechanism includes a mounting base fixed to the adjusting arm, a rotary drive component mounted on the mounting base, and a connecting disk driven by the rotary drive component and rotating relative to the mounting base, wherein the gripper is mounted on the connecting disk.

[0010] Preferably, the gripping surface of the gripper is V-shaped or arc-shaped, and a flexible anti-slip pad is embedded on the gripping surface.

[0011] Preferably, the bottom of the hydraulic outrigger is provided with a support foot plate.

[0012] Therefore, the auxiliary device for laying municipal heating pipelines using the above-described structure of this utility model has the following beneficial effects: (1) The longitudinal trolley adopts a tracked walking mechanism, which effectively solves the problem that the original device roller group is prone to slipping and getting stuck in the soil, sand and gravel and uneven ground of the foundation pit, greatly improving the terrain adaptability and enabling stable long-distance longitudinal movement; at the same time, the hydraulic outriggers (with support foot plates at the bottom) hinged at the four corners of the longitudinal trolley frame can increase the ground contact area, avoid device shaking due to uneven ground, and significantly improve construction stability and pipeline docking accuracy. (2) The control box on the transverse frame integrates the controller, hydraulic pump station and battery, and is equipped with a wireless remote control to replace the manual close-range operation of the original device. In the limited construction space of the foundation pit, it not only improves the convenience of operation, but also eliminates the safety hazards of operators. It can flexibly adapt to the control needs of complex construction scenarios. (3) The clamps are connected to the adjusting arm through the rotary mechanism, which can easily correct the circumferential misalignment of the pipe docking port without repeatedly adjusting the position of the longitudinal and transverse trolleys, thus greatly improving docking efficiency. In addition, the clamps adopt V-shaped or arc-shaped clamping surfaces and are fitted with flexible anti-slip pads, which not only broadens the range of compatible pipe diameters, but also avoids scratching the anti-corrosion layer on the outer wall of the pipe, while preventing the pipe from slipping during clamping, ensuring construction safety and pipe durability.

At least one fixed arm 3 is fixedly connected to the transverse frame 203. An adjusting arm 4 is slidably connected to the fixed arm 3 below it. A clamping jaw 6 that can close in opposite directions is installed at the lower end of the adjusting arm 4. The clamping surface of the clamping jaw 6 is V-shaped or arc-shaped, and a flexible anti-slip pad is embedded on the clamping surface, which can effectively prevent damage to the anti-corrosion layer of the pipeline while firmly clamping the pipeline. The longitudinal trolley 1 includes a longitudinal frame 102 and tracked vehicles arranged on the left and right sides of the longitudinal frame 102. The traveling mechanism 101 can utilize the complex and rugged terrain at the bottom of the pit; the longitudinal transfer frame 102 has retractable hydraulic outriggers 7 hinged at the four corners of its bottom, which can extend during operation to support and level the entire device, forming a stable working platform and preventing sinking or swaying under heavy loads; the bottom of the hydraulic outriggers 7 is equipped with support feet 8, which can increase the ground contact area and further enhance stability during operation; the transverse transfer frame 203 is equipped with a control box, which integrates a controller, hydraulic pump station and battery, combining power, control and energy into one, freeing the device from the constraints of external pipelines and enabling autonomous operation in the pit; the device is equipped with a wireless remote control that communicates with the controller, allowing for remote operation; the gripper 6 is connected to the lower end of the adjusting arm 4 through the rotating mechanism 5.

[0018] The lateral drive mechanism is a lateral gear 201 set. A rack 103 that meshes with the lateral gear 201 set is fixedly installed on the upper part of the longitudinal frame 102. A sealing protective cover 202 is provided outside the lateral gear 201 set to prevent sand and debris from entering the transmission system and improve reliability.

[0019] The rotary mechanism 5 includes a mounting base 501 fixed to the adjusting arm 4, a rotary drive 502 mounted on the mounting base 501, and a connecting plate 503 driven by the rotary drive 502 and rotating relative to the mounting base 501. The gripper 6 is mounted on the connecting plate 503. The rotary drive 502 can be a servo motor or a hydraulic motor, which can drive the clamped pipe to rotate around its own axis, thereby precisely adjusting the weld position of the pipe interface, facilitating alignment and welding.

[0020] Working principle: During use, the operator starts the device via wireless remote control, driving the tracked walking mechanism 101 to move above the pipeline in the pit; controls the hydraulic outriggers 7 to extend and compact the ground, stabilizing and leveling the entire vehicle; then controls the adjusting arms 4 to descend and the grippers 6 to close in opposite directions to clamp the pipeline; subsequently, the longitudinal trolley 1 and the transverse trolley 2 move together in the horizontal plane to initially adjust the pipeline position; then precisely control the raising and lowering of each adjusting arm 4 to adjust the pipeline posture and height, while simultaneously starting the slewing mechanism 5 to drive the pipeline to rotate around its axis, adjusting the interface weld to the optimal position; finally, precisely align the pipeline with the interface of the laid pipeline, complete the docking, release the grippers 6, retract the hydraulic outriggers 7, and move to the next work position.

[0021] Therefore, the present invention provides an auxiliary device for laying municipal heating pipelines with the above-mentioned structure, which improves terrain adaptability and construction stability, ease of operation and safety, pipeline connection efficiency and pipe diameter adaptability, and pipeline protection effect, while extending the life of the transverse transmission components and ensuring their accuracy.
