Description

Technical Field

[0001] The utility model relates to the technical field of grouting pipes, in particular to a grouting pipe burying device for municipal engineering construction. Background Technique

[0002] Municipal engineering refers to various buildings, structures, equipment, etc. set within the scope of urban planning and construction, and the government is responsible for providing public products and services. The grouting pipe burying device in municipal engineering construction is usually used for permanent sealing of cold joints, pipe leakage joints, gaps between diaphragm walls, etc. during concrete construction.

[0003] As disclosed in a grouting pipe burying device for municipal engineering construction in Chinese Patent CN118110838B, during the process of the excavating head advancing and excavating, when encountering hard objects or pipelines, the excavating head cannot continue to advance. At this time, when the rotating shaft continues to rotate for driving, the driving block will overcome the elastic force of the torsion spring, causing the follower block to rotate. The driving block will then cross over the follower block and no longer drive the third gear to rotate, that is, the excavating head will neither rotate nor continue to advance at this time, avoiding damage to the excavating head or underground pipelines.

[0004] For this structure, although it can avoid damage to the excavating head, when the excavating head cannot continue to advance, at this time the excavating head has already come into contact with hard objects, and this structure does not provide a buffer mechanism for the excavating head. Over time, the excavating head will still be damaged. Therefore, we propose a grouting pipe burying device for municipal engineering construction that can provide a buffer mechanism for the excavating head to avoid direct collision between the excavating head and hard objects, so as to extend the service life of the excavating head. Content of the Utility Model

[0005] The purpose of the utility model is to provide a grouting pipe burying device for municipal engineering construction to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A grouting pipe burying device for municipal engineering construction, including a rotating cylinder, vertical holes are provided on the outer wall of the rotating cylinder, an excavating tooth is provided below the rotating cylinder, and a processing component is provided below the rotating cylinder. The processing component includes a buffer component provided below the rotating cylinder, and a disassembly and assembly component is provided above the buffer component.

[0007] Preferably, the buffer component includes a connecting block clamped on the outer wall of the rotating cylinder, a sleeve is fixedly installed inside the connecting block, a spring is provided inside the sleeve, a limit ring is fixedly installed at the end of the spring, a sliding rod is fixedly installed on the side of the limit ring away from the spring, a damper is fixedly installed at the bottom of the connecting block, a sliding ring is fixedly installed at the end of the damper away from the connecting block, and a protective pipe is slidably arranged on the outer wall of the sliding ring.

[0008] Preferably, the disassembly and assembly component includes a card slot formed on the top surface of the connection block. A sliding slot is formed on the inner wall of the card slot. A first magnetic block is fixedly installed on the inner wall of the sliding slot. A second magnetic block is slidably arranged inside the sliding slot. A baffle is fixedly installed on one side of the second magnetic block away from the first magnetic block. A clamping block is fixedly installed on the outer wall of the rotating cylinder.

[0009] Preferably, one end of the sliding rod away from the limiting ring is fixedly installed with the sliding ring on the side away from the digging tooth. The sliding rod is slidably arranged with the sleeve. When the digging tooth is squeezed, the sliding ring slides into the protective tube, and the sliding ring drives the sliding rod to slide into the sleeve. The spring is squeezed by the limiting ring to buffer the digging tooth.

[0010] Preferably, the protective tube is fixedly installed at the bottom of the connection block. There are three dampers, which are distributed circumferentially around the center of the connection block. Under the protection of the protective tube, mud accumulation between the connection block and the sliding ring can be avoided. Under the limitation of the dampers, the shaking force generated by the spring can be avoided from affecting the buffering effect of the digging tooth.

[0011] Preferably, the second magnetic block and the first magnetic block are magnetically repulsive. There are six baffles, which are distributed circumferentially around the center of the rotating cylinder. Under the limitation of magnetic repulsion, the baffle can be pushed towards the outside of the sliding slot, so that the baffle clamps the clamping block. Under the shielding of the baffle, mud can be prevented from entering the card slot.

[0012] Preferably, the outer wall of the clamping block is arranged in an inclined plane, and one end of the baffle away from the second magnetic block is arranged in an arc surface. When the inclined plane of the clamping block is squeezed with the inclined plane of the baffle, the baffle can slide into the sliding slot. When the side of the clamping block away from its inclined plane contacts the bottom of the baffle, the baffle is not squeezed at this time. Under the limitation of magnetic repulsion, the end of the baffle away from the second magnetic block is in close contact with the outer wall of the rotating cylinder.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. The grouting pipe burying device for municipal engineering construction includes a buffer component as one of its parts. When the excavation teeth fixedly installed at the bottom of the slip ring are performing excavation work, in order to avoid damage to the excavation teeth caused by collision with hard objects, it is necessary to buffer the excavation teeth. When the excavation teeth come into contact with hard objects and cannot be excavated, the excavation teeth are squeezed, driving the slip ring to slide into the protective pipe. The slide bar fixedly installed at the end of the slip ring drives the limit ring to slide into the sleeve, compressing the spring inside the sleeve. The spring is used for buffering to avoid the excavation teeth directly colliding with hard objects forcefully. Then, the operator stops the rotation of the excavation teeth. When the spring buffers the extrusion force, it will generate a shaking force, which can be offset by the damper to improve the buffering effect of the excavation teeth. The slip ring is slidably arranged inside the protective pipe. Under the restriction of the protective pipe, it is possible to prevent soil from accumulating between the connecting block and the slip ring, thereby improving the buffering effect and extending the service life of the excavation teeth (the rotating cylinder, vertical hole, excavation teeth, and grouting pipe burying mechanism are existing publicly disclosed technologies in the comparative document, so their structures are not fully described in this case).

[0015] 2. The grouting pipe burying device for municipal engineering construction includes a disassembly and assembly component as one of its parts. When the excavation teeth are worn out after long-term use, they need to be replaced. At this time, the baffle and the second magnet are pushed into the chute, so that the baffle no longer clamps the clamping block, and the rotating cylinder and the excavation teeth are disassembled. When installing a new connecting block and excavation teeth, the clamping block contacts and squeezes the outer wall of the baffle. The inclined surface of the clamping block squeezes the outer wall of the baffle, causing the baffle to drive the second magnet to slide into the chute. When the side of the clamping block away from its inclined surface contacts the bottom of the baffle and the clamping block is engaged with the card slot, the baffle is no longer squeezed. Under the restriction of the magnetic repulsion between the second magnet and the chute, the baffle is pushed towards the outside of the chute, causing the baffle to clamp and restrict the clamping block, so as to quickly install the rotating cylinder and the excavation teeth. This structure can quickly disassemble and assemble the connecting block, excavation teeth, and rotating cylinder, thereby improving the efficiency of grouting pipe burying.

Specific embodiments

[0023] For a clearer understanding of the technical features, objectives, and effects of the present utility model, the specific embodiments of the present utility model will now be described with reference to the accompanying drawings. Embodiment 1

[0024] A preferred embodiment of a grouting pipe burying device for municipal engineering construction provided by the present utility model is as Figures 1 to 6 shown: A grouting pipe burying device for municipal engineering construction includes a rotary drum 1;

[0025] Vertical holes 2 are formed in the outer wall of the rotary drum 1;

[0026] Excavation teeth 3 are arranged below the rotary drum 1;

[0027] And a processing component 4 arranged below the rotary drum 1. The processing component 4 includes a buffer component 41 arranged below the rotary drum 1. The buffer component 41 includes a connecting block 411 clamped on the outer wall of the rotary drum 1. A sleeve 412 is fixedly installed inside the connecting block 411. A spring 413 is arranged inside the sleeve 412. A limit ring 418 is fixedly installed at the end of the spring 413. A sliding rod 414 is fixedly installed on the side of the limit ring 418 away from the spring 413. A damper 415 is fixedly installed at the bottom of the connecting block 411. One end of the damper 415 away from the connecting block 411 is fixedly installed with a slip ring 417. A protective tube 416 is slidably arranged on the outer wall of the slip ring 417.

[0028] In this embodiment, when the excavation tooth 3 fixedly installed at the bottom of the slip ring 417 performs tunneling work, in order to prevent the excavation tooth 3 from being damaged by collision with hard objects, it is necessary to buffer the excavation tooth 3. When the excavation tooth 3 contacts a hard object and cannot be excavated, the excavation tooth 3 is squeezed, driving the slip ring 417 to slide into the protective tube 416. The slide bar 414 fixedly installed at the end of the slip ring 417 drives the limit ring 418 to slide into the sleeve 412, compressing the spring 413 inside the sleeve 412. The spring 413 is used for buffering to prevent the excavation tooth 3 from directly colliding with a hard object forcefully. Then, the operator stops the rotation of the excavation tooth 3. When the spring 413 buffers the extrusion force, it will generate a shaking force itself, which can be offset by the damper 415 to improve the buffering effect of the excavation tooth 3. The slip ring 417 is slidably arranged inside the protective tube 416. Under the restriction of the protective tube 416, it is avoided that soil accumulates between the connection block 411 and the slip ring 417 to improve the buffering effect and extend the service life of the excavation tooth 3 (the rotating cylinder 1, the vertical hole 2, the excavation tooth 3 and the grouting pipe embedding mechanism are the prior art disclosed in the comparative document, so their structures are not fully described in this case).

[0029] Further, one end of the slide bar 414 away from the limit ring 418 is fixedly installed on the side of the slip ring 417 away from the excavation tooth 3. The slide bar 414 is slidably arranged in the sleeve 412. When the excavation tooth 3 is squeezed, the slip ring 417 slides into the protective tube 416, and the slip ring 417 drives the slide bar 414 to slide into the sleeve 412, and the spring 413 is squeezed by the limit ring 418 to buffer the excavation tooth 3.

[0030] Furthermore, the protective tube 416 is fixedly installed at the bottom of the connection block 411. There are three dampers 415, which are distributed circumferentially around the center of the connection block 411. Under the protection of the protective tube 416, it is avoided that soil accumulates between the connection block 411 and the slip ring 417. Under the restriction of the damper 415, it is avoided that the spring 413 generates a shaking force that affects the buffering effect of the excavation tooth 3. Embodiment 2

[0031] On the basis of Embodiment 1, a preferred embodiment of the grouting pipe embedding device for municipal engineering construction provided by the present utility model is as Figures 1 to 6 shown: The disassembly and assembly component 42 includes a card slot 421 opened on the top surface of the connection block 411. A chute 422 is opened on the inner wall of the card slot 421. A first magnet 423 is fixedly installed on the inner wall of the chute 422. A second magnet 424 is slidably arranged inside the chute 422. A baffle 425 is fixedly installed on the side of the second magnet 424 away from the first magnet 423. A clamping block 426 is fixedly installed on the outer wall of the rotating cylinder 1.

[0032] In this embodiment, when the digging tooth 3 is worn out after long-term use and needs to be replaced, the baffle 425 and the second magnet 424 are pushed into the chute 422, so that the baffle 425 no longer clamps the latch 426, and the rotating cylinder 1 and the digging tooth 3 are disassembled. When a new connecting block 411 and the digging tooth 3 are installed, the latch 426 contacts and presses against the outer wall of the baffle 425. The inclined surface of the latch 426 presses against the outer wall of the baffle 425, causing the baffle 425 to drive the second magnet 424 to slide into the chute 422. When the side of the latch 426 away from its inclined surface contacts the bottom of the baffle 425 and the latch 426 is clamped with the card slot 421, the baffle 425 is not pressed at this time. Under the restriction of the magnetic repulsion between the second magnet 424 and the chute 422, the baffle 425 is pushed towards the outside of the chute 422, so that the baffle 425 clamps and restricts the latch 426, and the rotating cylinder 1 and the digging tooth 3 are quickly installed. This structure can quickly disassemble and assemble the connecting block 411, the digging tooth 3 and the rotating cylinder 1 to improve the embedding efficiency of the grouting pipe.

[0033] Furthermore, the second magnet 424 and the first magnet 423 are magnetically repulsive. There are six baffles 425, which are distributed circumferentially around the center of the rotating cylinder 1. Under the restriction of magnetic repulsion, the baffle 425 can be pushed towards the outside of the chute 422, so that the baffle 425 clamps the latch 426. Under the shielding of the baffle 425, soil can be prevented from entering the card slot 421.

[0034] In addition, the outer wall of the latch 426 is arranged in an inclined surface, and the end of the baffle 425 away from the second magnet 424 is arranged in an arc surface. When the inclined surface of the latch 426 presses against the inclined surface of the baffle 425, the baffle 425 can slide into the chute 422. When the side of the latch 426 away from its inclined surface contacts the bottom of the baffle 425, the baffle 425 is not pressed at this time. Under the restriction of magnetic repulsion, the end of the baffle 425 away from the second magnet 424 fits and contacts the outer wall of the rotating cylinder 1.

[0035] The above is only a schematic specific embodiment of the present invention and is not intended to limit the scope of the present invention. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principle of the present invention shall fall within the scope of protection of the present invention. It should be noted that the components of the present invention are not limited to the above overall application. Each technical feature described in the specification of the present invention can be selected and used alone according to actual needs or combined with multiple items. Therefore, the present invention should reasonably cover other combinations and specific applications related to the inventive points of this case.
