Description

Technical Field

[0001] This utility model relates to the field of municipal construction technology, specifically to a quick-connect tooling for corrugated pipes in municipal engineering. Background Technology

[0002] In municipal engineering's outdoor pipe network projects, underground pipelines are typically used for water supply and drainage. Corrugated pipes are widely used in building drainage systems as rainwater and sewage pipes. Their corrugated structure can adapt to a certain degree of deformation, effectively preventing pipe rupture and leakage caused by factors such as foundation settlement and temperature changes. They are also widely used in urban drainage and sewage systems in municipal engineering, adapting to complex underground geological conditions and environmental changes, and reducing pipeline maintenance costs. The corrugated pipes used in water supply and drainage construction in municipal and building engineering are mostly PVC double-wall corrugated pipes with nominal outer diameters of 400mm, 500mm, 600mm, and 800mm. To reduce the difficulty of factory processing and transportation, the general length of corrugated pipes is 6000mm. Therefore, to meet the requirements of engineering construction, corrugated pipes need to be connected on-site. Due to the presence of corrugated layers on the inner and outer walls of the corrugated pipe and the nature of the PVC material, the corrugated pipes often fail to connect properly, the insertion length does not meet the specifications (one-quarter of the nominal outer diameter), and the corrugated pipes are frequently damaged, resulting in a significant waste of manpower and resources and affecting the quality of construction. Utility Model Content

[0003] The technical problem to be solved by this utility model is: to address the existing technical problems of difficult corrugated pipe connection and non-standard corrugated pipe connection length, a tooling that can quickly connect corrugated pipes and determine the corrugated pipe connection length is proposed.

[0004] To address the aforementioned problems, the present invention proposes the following technical solution: a quick-connection fixture for corrugated pipes, comprising a serrated track and a collar, wherein a track plate is provided at the lower end of the serrated track, and a serrated edge is provided at the top of one end of the track plate, and the bottom of an arc-shaped collar is fixedly connected to the track plate; the quick-connection fixture for corrugated pipes further comprises a transmission mechanism and a pressure rod, wherein the transmission mechanism is sleeved on the track plate, one pressure rod is connected to the collar fixed on the track plate, another pressure rod is fixedly connected to the transmission mechanism, and the bottom of another arc-shaped collar is fixedly connected to the transmission mechanism.

[0005] Preferably, scale lines and scale values ​​are provided on the side of the track plate, and both scale lines and scale values ​​are located below the serrations.

[0006] Preferably, the transmission mechanism includes a connector, a housing, a rotating shaft, and a gear. The transmission mechanism being fitted onto the track plate means that the housing of the transmission mechanism is fitted onto the track plate, the rotating shaft passes through the housing, and both ends of the rotating shaft extend out of the housing. The two sides of the connector are fixedly connected to the rotating shaft extending out of the housing. The gear is mounted on the rotating shaft, the gear is fixedly connected to the rotating shaft, and the gear is embedded in the housing. The bottom of the gear meshes with the serrations on the top of the track plate.

[0007] Preferably, the outer shell includes a side shell plate, an upper shell plate, and a lower shell plate. The two side shell plates are arranged in parallel. The two ends of the upper shell plate are seamlessly connected to the top of the two side shell plates to form a whole. The two ends of the lower shell plate are seamlessly connected to the bottom of the two side shell plates to form a whole. Both the upper shell plate and the lower shell plate are located behind the gear.

[0008] Preferably, the other pressure rod being fixedly connected to the transmission mechanism means that the lower end of the other pressure rod is fixedly connected to the upper end of the joint; the bottom of the other arc-shaped collar being fixedly connected to the transmission mechanism means that the bottom of the other arc-shaped collar is fixedly connected to the upper shell plate.

[0009] Preferably, the transmission mechanism further includes a connecting rod that passes through the upper ends of the two side shell plates of the outer casing, with both ends of the connecting rod extending out of the side shell plates and both ends of the connecting rod being fixedly connected to the side shell plates.

The two ends of the rotating shaft pass through the waist-shaped holes on the two side shells respectively, and both ends of the rotating shaft extend out of the side shells.

[0011] The beneficial technical effects of this utility model are as follows: By using a collar to fit over the corrugated pipe, the corrugated pipe can be securely tightened, preventing slippage relative to the collar; and by using a transmission mechanism to move the collar and corrugated pipe, the corrugated pipe connection can be completed conveniently and quickly. The fixture is equipped with a pressure rod, allowing workers to operate upright instead of bending over. This device significantly reduces worker fatigue and the time spent in trenches. Furthermore, this fixture has a simple structure, low cost, and is easy and practical to operate, saving manpower and resources; it is time-saving, labor-saving, quick, and highly efficient.

Detailed Implementation

[0013] The present invention will be further described below with reference to the embodiments and accompanying drawings: Example 1

[0014] like Figure 1 and Figure 2 As shown, in this embodiment, the following is set Figure 1 The left side is the front, and the right side is the rear. The bellows quick-connect tooling includes a serrated track, a collar 2, a pressure rod 3, and a transmission mechanism. The serrated track includes a track plate 11, serrations 12, scale lines 13, and scale values. The serrated track has a track plate 11 at its lower end, and serrations 12 at the top of the rear end of the track plate 11. Scale lines 13 and corresponding scale values ​​are provided on the side of the track plate 11, and both scale lines 13 and scale values ​​are located below the serrations 12. In this embodiment, there are two serrated tracks, two pressure rods 3, and two collars 2. The two serrated tracks are arranged in parallel, and the bottom of an arc-shaped collar 2 is fixedly connected to the front end of each of the two track plates 11. The pressure rod 3 is n-shaped, and the bottom of one pressure rod 3 is fixedly connected to both sides of the collar 2. Pushing the pressure rod 3 forward or backward can tilt the collar 2 forward or backward, thereby loosening or tightening the bellows.

[0015] like Figure 1 , Figure 3 and Figure 4 As shown, the transmission mechanism includes a connector 4, a housing, a rotating shaft 6, a gear 7, and a connecting rod 8. The housing includes a side shell plate 51, an upper shell plate 52, and a lower shell plate 53, all of which are flat, plate-like structures. The two side shell plates 51 are arranged in parallel, and the upper shell plate 52 and lower shell plate 53 are fixedly connected to the rear ends of the two side shell plates 51. The two ends of the upper shell plate 52 are seamlessly connected to the top of the two side shell plates 51 to form a single unit, and the two ends of the lower shell plate 53 are seamlessly connected to the bottom of the two side shell plates 51 to form a single unit.

[0016] The rotating shaft 6 passes through two side shell plates 51, and both ends of the rotating shaft 6 extend out of the side shell plates 51. In this embodiment, the upper end of the connector 4 is inverted V-shaped, and the lower end consists of two flat metal plates. The upper end of the connector 4 is welded and fixed to the lower end of another pressure rod 3, and the two sides of the lower end of the connector 4 are fixedly connected to the rotating shaft 6 extending out of the outer shell. The gear 7 is mounted on the rotating shaft 6 and welded and fixed to the rotating shaft 6. When the rotating shaft 6 rotates, it will drive the gear 7 to rotate. The gear 7 is embedded in the outer shell, and the bottom of the gear 7 meshes with the serrations 12 on the top of the track plate 11.

[0017] The connecting rod 8 passes through the upper ends of the two side shell plates 51 of the outer casing. The outer casing of the transmission mechanism is fitted onto the sawtooth track, with a gap between the connecting rod 8 and the sawtooth 12 on the sawtooth track. Both ends of the connecting rod 8 extend out of the side shell plates 51 and are fixedly connected to the side shell plates 51. The connecting rod 8 reinforces the two side shell plates 51 to prevent them from undergoing large deformations during operation. The gear 7 and the rotating shaft 6 are located between the connecting rod 8 and the upper shell plate 52, and the bottom of another arc-shaped collar 2 is fixedly connected to the upper shell plate 52.

[0018] like Figure 5 As shown, both side shell plates 51 have oblong holes 511, with the length of the oblong holes 511 being perpendicular to the vertical direction. The two ends of the rotating shaft 6 pass through the oblong holes 511 on the two side shell plates 51 respectively, and both ends of the rotating shaft 6 extend out of the side shell plates 51. The rotating shaft 6 and the gear 7 can move perpendicularly along the oblong holes 511.

[0019] like Figures 1 to 5 As shown, When the worker lifts the pressure rod 3 at the back, the rotating shaft 6 and the gear 7 will move upward together. At this time, the gear 7 will separate from the serration 12 on the top of the track plate 11, so the movement or rotation of the gear 7 will not be hindered by the serration 12 on the top of the track plate 11.

[0020] When the worker presses the pressure rod 3 down, pushing it forward causes the lower end of the pressure rod 3 to sequentially drive the connector 4, the rotating shaft 6, and the gear 7 to rotate. At this time, the gear 7 is obstructed by the serrations 12 on the top of the track plate 11, causing the entire transmission mechanism and the collar 2 fixed on the upper shell plate 52 to move forward together.

[0021] The process of quickly connecting two corrugated pipes using the corrugated pipe quick-connect fixture of this embodiment is as follows: First, place the two corrugated pipes to be connected under the two collars 2 of the fixture, align the joints of the two corrugated pipes, and press the two corrugated pipes together with the collars 2. Figure 1The pressure rod 3 at the rear is pushed forward, causing the rear collar 2 and the bellows to move forward a short distance together, thus allowing a small section of the two bellows to fit together. The precise value of this short distance movement can be determined from the scale line 13 and corresponding graduations on the side of the track plate 11. Then, the pressure rod 3 is lifted upwards, causing the gear 7 to separate from the serration 12 at the top of the track plate 11. After resetting the pressure rod 3, it is pressed downwards again, and then pushed forward once more, causing the rear collar 2 and the bellows to move forward a short distance again. By repeating the above steps and carefully observing the movement distance of the rear bellows, the two bellows can be quickly fitted together.

[0022] Obviously, any improvements or modifications made without departing from the principles described in this utility model should be considered within the scope of protection of this utility model.
