Municipal heating projects refer to the engineering technologies and facilities that supply steam, hot water and fuel gas to urban users in a centralized manner to meet their thermal energy needs. During the pipeline construction process of municipal heating projects, the pipelines need to be connected by a docking auxiliary device and then fixed in a corresponding manner.

[0004] However, the above-mentioned publicly disclosed solutions have the following shortcomings: In actual use, the above solutions are not convenient for the pipes to get close to each other during the docking process. The above devices require the two sets of pipe axes to be parallel to each other before they can get close. In actual use, it is difficult to maintain the parallel state of the two sets of pipes.

[0005] This utility model proposes a pipeline connection device for municipal heating projects to solve the problem. Utility Model Content

[0025] The following is in conjunction with the appendix Figures 1-3 The present invention will be described in further detail below.

[0026] Example 1: This example provides a pipe connection device for a municipal heating project, such as... Figures 1-3 As shown, it includes a base 1, a sliding component 2 connected to the top of the base 1, a limiting component 3 connected to the top of the sliding component 2 for connecting the pipe, and a proximity component 4 symmetrically arranged on the side of the limiting component 3 for connecting and approaching.

[0027] The sliding component 2 includes a transverse sliding groove 201 disposed on the top of the base 1. A sliding plate 202 is slidably connected to the inner wall of the transverse sliding groove 201. A longitudinal sliding groove 203 is provided on the top of the sliding plate 202. The longitudinal sliding groove 203 is perpendicular to the direction of the transverse sliding groove 201. A sliding base 204 is slidably connected to the top of the longitudinal sliding groove 203 for sliding position adjustment.

[0028] The limiting component 3 includes a damping telescopic column 301 connected to the top of the sliding base 204, a lifting plate 302 connected to the top telescopic end of the damping telescopic column 301, and a support column 303 connected to the top of the lifting plate 302.

[0029] The top of the support column 303 is rotatably connected to a support limiting member 304, the top of the support limiting member 304 is threadedly connected to a limiting bolt 305, the outer arc surface of the limiting bolt 305 is slidably connected to a limiting pressing member 306, and the top of the support limiting member 304 is provided with an arc-shaped groove.

[0030] The bottom of the limiting pressing member 306 is provided with a mating groove that aligns with the arc-shaped groove on the top of the supporting limiting member 304, and the nut on the top of the limiting bolt 305 contacts and presses against the top of the limiting pressing member 306.

[0031] The proximity component 4 includes a rotating connector 401 that is rotatably connected to the side of the lifting plate 302. A rotating bracket 402 is connected to the side of the rotating connector 401 away from the lifting plate 302. The rotation direction of the rotating bracket 402 is perpendicular to the rotation direction of the rotating connector 401.

[0032] The specific working principle is as follows: This device can achieve close-to-connection stability of the pipeline. When this device is in use, the base 1 facilitates the installation and fixation of the bottom of the device. After the device is fixedly installed, the position of the limiting component 3 can be moved by the combination of the freely sliding sliding plate 202 and the sliding base 204, so as to facilitate the connection and fixation of the limiting component 3 with the existing pipeline. The lifting plate 302 is moved to the position below the existing pipeline. At this time, the pipeline is between the supporting limiting component 304 and the limiting pressing component 306. At this time, the relative fixation effect between the device and the pipeline can be achieved by rotating the limiting bolt 305.

[0033] After the pipe is fixed relative to the device, the bidirectional threaded rod 404 is rotated. By rotating the bidirectional threaded rod 404, the two sets of threaded parts 403 are brought closer to each other, which in turn drives the two sets of limiting parts 3 to bring closer to each other. Since the distance between the two threaded parts 403 is the smallest when they are in parallel docking state, when the bidirectional threaded rod 404 can no longer be rotated, the two sets of limiting parts 3 will bring closer to each other and align, thus achieving the effect of pipe docking of the device.

[0034] Example 2: This example provides a pipe connection device for municipal heating projects, such as... Figures 1-3 As shown, the rotating bracket 402 is rotatably connected to a threaded component 403. The threaded component 403 has an internal threaded hole. The threaded component 403 is threadedly connected to a bidirectional threaded rod 404 through the internal threaded hole. Rotating knobs 405 are respectively connected to both ends of the bidirectional threaded rod 404.

[0035] The base 1 is provided with two sets of sliding components 2 and limiting components 3. The two sets of sliding components 2 and limiting components 3 are connected by a bidirectional threaded rod 404 near the component 4. The two sets of sliding components 2 and limiting components 3 are mirror symmetrical.

[0036] The specific working principle is as follows: This device can effectively improve the efficiency and accuracy of pipe docking. In actual use, it is not necessary for the two sets of pipes to be in a parallel state so that the pipes can approach and dock with each other during the rotation of the bidirectional threaded rod 404.

[0037] The above description is a further detailed explanation of the present invention in conjunction with specific preferred embodiments, which is intended to enable those skilled in the art to understand and apply the present invention. However, it should not be assumed that the specific implementation of the present invention is limited to these descriptions.
