Description

Technical Field

[0001] This utility model relates to an auxiliary tool, specifically a corrugated pipe socket auxiliary device, belonging to the field of corrugated pipe installation technology. Background Technology

[0002] In current construction projects, corrugated pipes are widely used in post-tensioned building construction. Their main function is to protect the internal structure during concrete pouring, ensuring that the internal structure is not contaminated or damaged, and guaranteeing the quality of tensioning. Traditional corrugated pipe connections are mainly made by manual pushing and pulling, requiring multiple people to work together. This results in high labor intensity for workers, making it difficult to ensure the quality of pipe joint connections when project schedules are tight, and also wasting construction time.

[0003] A search revealed that Chinese utility model publication CN 212763268U discloses a corrugated pipe socket auxiliary device, which mainly consists of two parallel receiving guide rods. A fixed arc-shaped rod is rotatably connected between the right ends of the two receiving guide rods. A grooved rack is provided on the top left side of the two receiving guide rods. A receiving slider plate is abutted against the lower left side of each of the two receiving guide rods. A guide rail groove is provided on the receiving slider plate. A movable arc-shaped rod is rotatably connected between the two receiving slider plates. A crankshaft mounting seat is provided on the top of the two receiving slider plates. A transmission crankshaft and a ratchet block are rotatably mounted on each of the two crankshaft mounting seats. A drive bent rod is connected between the outer ends of the two transmission crankshafts. However, during use, the above-mentioned corrugated pipe socket auxiliary device has the following problems: 1. There is a certain tension between the two corrugated pipes after the two sections are connected by sockets. The tension is overcome by two sets of ratchet blocks. The ratchet blocks are in a tight state and are not easy to loosen, making it difficult to remove the corrugated pipe socket auxiliary device from the corrugated pipe; 2. The corrugated pipe socket auxiliary device can usually only be used on corrugated pipes of a limited size. If corrugated pipes of various specifications and sizes are used, multiple models of auxiliary tools are required, which increases the operation process.

[0079] Specifically, the transmission assembly 22 includes a connecting column 221, which is connected to the upper part of one end of the movable seat 21;

[0084] Active pawl mounting rod 226 is connected to the upper part of the connecting plate 225;

[0085] an active pawl 227, wherein the active pawl 227 is mounted on an active pawl mounting rod 226 via a torsion spring, and the active pawl 227 is in meshing connection with the upper part of a ratchet wheel 224;

[0086] wherein the fixing plate 23 is arranged outside the connecting plate 225.

[0087] further, the ratchet wheel non-return assembly 24 comprises:

[0088] a mounting seat 241, wherein the mounting seat 241 is connected to the inner bottom of the moving seat 21 at a side away from the sliding chute;

[0089] a non-return pawl 242, wherein the non-return pawl 242 is mounted in the mounting seat 241 via a torsion spring and a connecting shaft;

[0091] further, the movable clamping member 3 is fixedly connected to the moving seat 21 of the transmission mechanism 2;

[0092] wherein the movable clamping member 3 consists of a plurality of clamping sections, and inner connecting plates and outer connecting plates of the plurality of clamping sections are alternately arranged and connected by pins.

[0093] In the present utility model, the design of the movable clamping member 3 not only ensures the flexibility of the clamping member, but also provides strong adaptability, especially when dealing with corrugated pipes of different sizes, the angles between the clamping sections can be automatically adjusted to adapt to corrugated pipes of various sizes and shapes.

[0094] further, both ends of the fixed clamping member 4 are also fixedly connected to the rack 1 via connecting pieces 41, wherein the main body of the fixed clamping member 4 has the same shape and structure as the movable clamping member 3.

[0095] specifically, the synchronous transmission rod 5 generally has an inverted U-shaped or square C-shaped structure, and the synchronous transmission rod 5 comprises:

[0096] connecting rods 51, wherein the connecting rods 51 are arranged opposite to each other, and the lower ends of the connecting rods 51 are detachably connected to the connecting plate 225 of the transmission mechanism 2;

[0097] a cross bar 52, wherein both ends of the cross bar 52 are respectively hinged to the upper parts of the connecting rods 51 at corresponding ends.

[0098] specifically, the cross bar 52 is a fixed rod or a telescopic rod, and a protective pad is further provided on the cross bar 52.

[0099] In this invention, the protective pad provided on the crossbar 52 can significantly improve the user experience of the operator, increase the comfort and stability of the grip, effectively reduce fatigue, slippage risk and hand injury during operation, thereby improving operation efficiency and safety.

[0100] Furthermore, the control mechanism 6 includes:

[0101] Control component 61 is detachably mounted on crossbar 52 via a connecting ring;

[0102] Pull rope 62, one end of which is connected to control component 61, and the other end passes through connecting plate 225 and is connected to drive pawl 227 and check pawl 242 of transmission mechanism 2 respectively.

[0103] The control component 61 is used to drive the active pawl 227 and the anti-return pawl 242 to control their engagement or disengagement with the ratchet 224.

[0104] In this invention, a protective sleeve is also fitted onto the outer side of the pull rope 62. The control mechanism 6 moves the active pawl 227 and the check pawl 242 connected to it via the pull rope 62, thereby controlling them to disengage from the ratchet 224, facilitating the movement of the transmission mechanism 2.

[0105] Furthermore, a protective layer is connected to the outer side of the movable card connector 3 and the fixed card connector 4, and the protective layer is provided with anti-slip texture.

[0106] In this utility model, the movable card connector 3 and the fixed card connector 4 are generally arc-shaped or C-shaped.

[0107] In this invention, the outer sides of the movable connector 3 and the fixed connector 4 are provided with a protective layer, which can effectively isolate the direct contact between the connector and the corrugated pipe 7, and prevent the corrugated pipe from being scratched, crushed or worn during installation, disassembly or operation, thus extending the service life of the corrugated pipe. At the same time, the protective layer can provide additional anti-corrosion protection for the movable connector 3 and the fixed connector 4, extending their service life, and the anti-slip texture can also increase the friction when connected with the corrugated pipe 7.

[0108] In summary, the corrugated pipe socket auxiliary device with the above-mentioned design structure needs to be manufactured and installed as a backup before it can be used.

[0109] When using it, the construction workers first insert the two corrugated pipes 7 to be installed together slightly back to back, so that the head of the rear corrugated pipe 7 is inserted into the tail of the front corrugated pipe 7.

[0110] Then, the construction workers placed the movable locking piece 3 and the fixed locking piece 4 into the grooves on the outer surface of the upper part of the two corrugated pipes 7 respectively. The two locking pieces will adjust adaptively to achieve automatic locking.

[0111] Next, the construction workers grasped the horizontal bar 52 on the upper part of the synchronous transmission rod 5 and shook the horizontal bar 52, which caused the connecting rods 51 connected to both ends of the horizontal bar 52 to synchronously drive the connecting plate 225 to rotate around the connecting column 221. At the same time, the active pawl 227 installed on the connecting plate 225 pushed the ratchet 224 to rotate, so that the ratchet 224 drove the key-connected gear 223 to move, and then the gear 223 drove the rack 1 that meshed with it to move, gradually shortening the distance between the moving locking part 3 and the fixed locking part 4. Meanwhile, the anti-return pawl 242 continuously engaged with the ratchet 224 under the action of the torsion spring to prevent rotation.

[0112] Finally, by continuously shaking the crossbar 52, the construction workers, in cooperation with the transmission assembly 22, the ratchet stop assembly 24, and the rack 1, gradually move the rear bellows 7 into the front bellows 7 until the rear bellows 7 is completely inside the front bellows 7.

[0113] During disassembly, the construction worker only needs to move the handle on the control component 61 toward the crossbar 52, which will drive the active pawl 227 and the check pawl 242 connected to it to move via the pull rope 62, thereby controlling them to disengage from the ratchet 224. This facilitates the movement of the transmission mechanism 2, and the auxiliary tool can be easily removed directly from the two bellows 7. This solves the problem that traditional pawls are in a tight state, making them difficult to loosen and remove from the bellows 7, thus improving construction efficiency.

[0114] During the use of the aforementioned installation clips, since both the movable clip 3 and the fixed clip 4 are composed of alternating inner and outer plates of multiple clip sections connected by pins, they can adaptively adjust according to the outer diameter of different bellows, achieving automatic locking. In addition, under the gravity of the rack 1, the transmission mechanism 2, and the synchronous transmission rod 5, the matching sleeves of the movable clip 3 and the fixed clip 4 can be engaged in the grooves on the outer surface of the corresponding bellows 7, ensuring stability and accuracy during installation, greatly improving the efficiency and flexibility of bellows installation, while reducing labor intensity and possible damage.

[0115] During use, when a pulling force is applied to the synchronous transmission rod 5, the active pawl 227 will pass over a portion of the teeth of the ratchet 224 and engage with the corresponding teeth. At the same time, under the limiting action of the check pawl 242, the ratchet 224 will not rotate, and thus the gear 223 will not drive the rack 1 to move. When a pushing force is applied to the synchronous transmission rod 5, the active pawl 227 will push the ratchet 224 to rotate, and then the ratchet 224 will drive the key cylinder 222 connected to it to drive the gear 223 to rotate. Finally, the gear 223 will drive the rack 1 meshed with it to move.

[0116] During use, the transmission assembly 22 and the ratchet stop assembly 24 cooperate to form a ratchet mechanism, which has the functions of unidirectional transmission and preventing reverse movement.

[0117] When operating the corrugated pipe socketing auxiliary device, the distances between the two transmission mechanisms 2 on the two racks 1 may be different. The construction personnel can make auxiliary adjustments through the control mechanism 6. Alternatively, depending on the specific socketing situation, it may not be necessary for the two transmission mechanisms 2 to be at the same distance relative to the corresponding racks. The corrugated pipe socketing work can be flexibly achieved through the cooperation of the control mechanism 6 and the synchronous transmission rod 5.

[0118] This utility model is not limited to the transmission method in which the transmission component 22 and the ratchet stop component 24 cooperate. Other forms can also be used, such as worm gear, gear rack, slider rail, etc. As long as the transmission mechanism can realize the movement of the movable locking part 3 relative to the fixed locking part 4, it is within the protection scope of this application.

[0119] In this utility model, both the movable connector 3 and the fixed connector 4 are made of chains to adapt to and meet the needs of corrugated pipes of different diameters and sizes.

[0120] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
