Description

Technical Field

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

[0002] Heating pipelines are pipelines that transport steam and hot water. They deliver the heat energy produced by the boiler to indoor heating equipment through heat media such as steam and hot water to meet the needs of production and life. The scattered pipelines in the indoor environment are not suitable for moving with cranes, so small handling equipment is needed. During the laying process, depending on different terrains and needs, some heating pipelines are laid underground, while others need to be erected at a certain height above the ground.

[0003] For example, patent document CN221642519U discloses a handling device used in municipal engineering pipeline construction, belonging to the field of pipeline construction technology. It includes a handling mechanism and a transport vehicle. The handling mechanism includes a lifting rod, with both ends fixedly connected to a handling rod. A connecting rod is fixedly connected to the middle of the handling rod, and soft ropes are fixed to both ends of the connecting rod. A fixing claw is fixedly connected to the end of the soft rope away from the connecting rod. A binding rope is tied to the side of the connecting rod. A support plate is provided on the side of the connecting rod away from the lifting rod, with both sides of the upper part of the support plate fixedly connected to the handling rod. A baffle is provided on the upper surface of the rear end of the transport vehicle. This improved handling device utilizes the lever principle to handle pipelines, saving labor costs. The fixing claw and binding rope provide multi-point fixation of the pipeline, improving stability during handling. After handling, the pipeline can be placed on top of the transport vehicle. Multiple pipelines can be transported simultaneously in one process, improving work efficiency.

[0004] In the above-mentioned device, loading and unloading both require the use of a handling mechanism to lift and move each material. In practical applications, this loading and unloading method leads to excessive labor intensity for workers and low loading and unloading efficiency. Therefore, a handling device for heating pipeline construction that can quickly load and unload materials is proposed. Utility Model Content

Therefore, they should not be construed as limitations on this utility model.

[0029] The present invention will be further described below with reference to the accompanying drawings:

[0030] like Figures 1-8As shown, a handling device for heating pipeline construction includes a mobile trolley, which includes a mobile frame 101. A rear support 103 is bolted to the rear of the mobile frame 101. Two symmetrically arranged front supports 105 are welded to the front of the mobile frame 101. A support shaft 106 is rotatably connected to the front bearing of the front support 105. A material receiving mechanism is provided on the mobile frame 101, which includes two lifting forks 204 welded to the support shaft 106. A tilting mechanism is provided above the mobile frame 101, which includes a storage platform 304 hinged to the front end of the support shaft 106. Two symmetrically arranged pins 306 are welded and fixed at the rear end. An inclined lever 301 is rotatably connected to the rear bracket 103. A push groove 305 is opened at the lower end of the inclined lever 301, and the push groove 305 is pin-connected to the pins 306. A limit pin 302 is rotatably connected to the other end of the inclined lever 301. Two limit holes 303 are opened at the upper rear side of the rear bracket 103. The other end of the limit pin 302 can be movably connected to the limit holes 303. A baffle 307 is fixedly connected to the upper rear side of the storage platform 304. A limit mechanism is provided on the storage platform 304. In order to facilitate pipeline construction and improve pipeline handling efficiency, a heating pipeline construction method is proposed. This industrial handling device adjusts the inclination angle of the storage platform 304, utilizing the cylindrical shape of the pipe to allow it to roll on the platform. Combined with a limiting mechanism, this enables the pipe to be loaded and unloaded. The storage platform 304 is in a loaded state when its rear end is lower than its front end, and vice versa. During loading and unloading, the operator pushes the mobile frame 101 forward, causing the lifting fork 204 to pass under the pipe. The lifting fork 204 then flips up, allowing the pipe to roll into the storage platform 304. The limiting mechanism then limits the pipe's movement during transport, preventing excessive swaying. This completes the unloading process. During material handling, the operator cancels the engagement between the limit pin 302 and the limit hole 303, and then drives the tilting lever 301 to rotate. The tilting lever 301 drives the storage platform 304 to rotate by pushing the engagement between the slide groove 305 and the pin 306, so that the rear end of the storage platform 304 is higher than the front end, thus switching to the unloading state. In this state, the pipe will roll forward. To prevent the pipe from rolling too fast, the lifting fork 204 rotates during unloading so that the pipe falls into the lifting fork 204. Then the lifting fork 204 drives the pipe to rotate to vertical, so that the pipe touches the ground. When the operator moves the mobile frame 101, the lifting fork 204 disengages from the pipe, thus completing the unloading.

[0031] The mobile trolley also includes four casters 102 bolted to the bottom of the mobile frame 101. A push handle 104 is welded to the top of the rear support 103. By gripping the push handle 104, the device can be moved. The casters 102 ensure that the mobile trolley can move freely in multiple directions.

[0032] The material receiving mechanism also includes a connecting shaft 205 rotatably connected to the top of the mobile frame 101 by bearings. Drive sprockets 202 are keyed to both ends of the connecting shaft 205. A material receiving lever 201 is bolted to the connecting shaft 205. Driven sprockets 203 are keyed to both ends of the support shaft 106. The drive sprockets 202 and driven sprockets 203 are connected by a chain. The lifting fork 204 is L-shaped and made of alloy steel. The front end of the lifting fork 204 is sloped. The material receiving lever 201 is gate-shaped. Workers push the mobile trolley to allow the lifting fork 204 to pass through the pipe. At the bottom of the channel, the worker then steps on the receiving lever 201 to rotate it. The receiving lever 201 drives the connecting shaft 205 to rotate, which in turn drives the drive sprocket 202 to rotate. The drive sprocket 202 drives the driven sprocket 203 to rotate via a chain, which in turn drives the support shaft 106 to rotate. The support shaft 106 then drives the lifting fork 204 to rotate, lifting the pipe. The pipe then rolls into the storage platform 304. This mechanism utilizes the lever principle, enabling the lifting fork 204 to lift heavier pipes, thus reducing the labor intensity of the workers.

[0033] The limiting mechanism includes three evenly arranged sliding rods 403 welded and fixed within the storage platform 304. Four supporting sliders 405 are mounted on the sliding rods 403. Limiting connecting rods 406 are hinged to the top of each supporting slider 405, and adjacent limiting connecting rods 406 are hinged together. Two edge supporting sliders 405 are bolted to the storage platform 304, while the remaining supporting sliders 405 are slidably connected to the sliding rods 403. A driving assembly is located at the bottom of the storage platform 304. The driving assembly includes a driving plate 401 slidably connected to the bottom of the storage platform 304. A driving telescopic rod 402 is bolted to the lower rear end of the storage platform 304. The driving telescopic rod 402 can be an electric telescopic rod, which is existing technology; its specific structure will not be described here. The output end of the driving telescopic rod 402 is bolted to the driving plate 401. Several guide grooves 404 are provided on the driving plate 401. The guide grooves 404 are slidably connected to the bottom of the movable supporting sliders 405. The guide grooves 404 include straight grooves and inclined grooves. The movement sequence of the support slider 405 is controlled by changing the position of the inclined slide relative to the straight slide. The foremost guide slide 404 is an inclined slide located at the rear end of the straight slide, the middle guide slide 404 is an inclined slide located in the middle of the straight slide, and the rearmost guide slide 404 is an inclined slide located at the front end of the straight slide. Thus, when the drive plate 401 drives the limit link 406 to rise, the rearmost limit link 406 rises first, followed by the middle limit link. 406 rises, followed by the front limiting link 406. This limiting mechanism enables single-pipe limiting collection or unloading. During operation, the drive telescopic rod 402 pushes the drive plate 401 to move. The drive plate 401 drives the two middle support sliders 405 to move through the guide slide 404. The support sliders 405 push the limiting link 406 to move. Subsequently, the limiting link 406 drives another limiting link 406 to move. The two limiting links 406 rise upwards to limit the pipe.

[0034] The front end of the baffle 307 is fixedly connected to a first protective pad 308, and two second protective pads 407 are fixedly connected to the front and rear of the limiting rod 406. The setting of the first protective pad 308 and the second protective pad 407 ensures that the material is stored or discharged in the pipe.

[0035] Working principle: During pipe loading and unloading, the worker pushes the mobile frame 101 forward, allowing the lifting fork 204 to pass under the pipe. The worker then steps on the receiving lever 201 to rotate it. The receiving lever 201 drives the connecting shaft 205 to rotate, which in turn drives the drive sprocket 202. The drive sprocket 202, via a chain, drives the driven sprocket 203 to rotate, which in turn drives the support shaft 106 to rotate. The support shaft 106 then drives the lifting fork 204 to rotate, causing it to flip up and allow the pipe to roll into the storage platform 304. Subsequently, the drive telescopic rod 402 pushes the drive plate 401 to move. The drive plate 401, through the guide groove 404, drives the two middle support sliders 405 to move. The support sliders 405 push the limiting link 406 to move, which in turn drives another limiting link 406 to move. Both limiting links 406 rise upwards, limiting the pipe's movement. To prevent significant shaking during transportation, when unloading the pipe, the operator cancels the engagement between the limit pin 302 and the limit hole 303, and then drives the tilt lever 301 to rotate. The tilt lever 301 drives the storage platform 304 to rotate by pushing the engagement between the slide groove 305 and the pin 306, making the rear end of the storage platform 304 higher than the front end, thus switching to the unloading state. In this state, the pipe will roll forward. To prevent the pipe from rolling too fast, the lifting fork 204 rotates during unloading, causing the pipe to fall into the lifting fork 204. Then, the lifting fork 204 drives the pipe to rotate to a vertical position, so that the pipe touches the ground. When the operator moves the mobile frame 101, the lifting fork 204 disengages from the pipe, thus completing the unloading. Through the setting of the limit mechanism, the single unloading function can be realized, thereby increasing the applicability of the device. When transporting long pipes, two of these devices can be used to support both ends respectively, realizing the handling of long pipes.
