[0002] In recent years, with the rapid development of my country's cities, more and more municipal road construction has shown a rapid development trend, and the construction of various types of pipelines on urban roads is also astonishing. During the construction process, the design and construction of municipal pipelines are also increasing. In terms of drainage pipe installation, the traditional installation method of drainage pipes is to lift the pipes by crane and use manual hand winch to cooperate with installation, bracket hand winch lifting and manual coordination and balanced installation and other traditional installation methods.

[0003] The common installation method of socket-and-spigot concrete drainage pipes is to use a crane to lift the drainage well chamber and manually install it with a hand winch. Most traditional installation methods rely on the workers' construction experience to make homemade lifting devices and tools. These construction methods are prone to slow transfer speeds and low installation qualification rates, resulting in rework, waste of costs, and delays in construction schedules. In serious cases, it will affect the construction quality. In addition, since the conventional methods have complicated construction steps and require multiple people to work at the same time, the probability of construction errors increases, which in turn increases the difficulty of construction and leads to low pipeline installation efficiency.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1:

[0021] See also Figure 1-3 In this embodiment, an automatic drain pipe clamp includes a supporting beam 2, a first support plate 3, a second support plate 4, a third support plate 5, a fourth support plate 6, a first support arm 7, a second support arm 8, a third support arm 9 and a fourth support arm 10. The first support plate 3 and the second support plate 4 are both hinged on the right side of the supporting beam 2, and the two are abutted against each other. The third support plate 5 and the fourth support plate 6 are both hinged on the left side of the supporting beam 2, and the two are abutted against each other. The first support arm 7 is hinged on the right side of the first support plate 3, the second support arm 8 is hinged on the left side of the second support arm 8, the third support arm 9 is hinged on the right side of the third support plate 5, and the fourth support arm 10 is hinged. Connected to the left side of the fourth arm 10, the first arm 7 and the second arm 8 are staggered and abutted against each other, and the centers of the abutting parts of the two are hinged through a hinge shaft, the third arm 9 and the fourth arm 10 are staggered and abutted against each other, and the centers of the abutting parts of the two are hinged through a hinge shaft, and the first arm 7, the second arm 8, the third arm 9 and the fourth arm 10 are fixed with a clamping plate 11 on the inner side and near the bottom end thereof, and a mounting rod 17 is fixed laterally on the right side of the second support plate 4, and a locking gate plate 19 is rotatably connected to the outer side of the mounting rod 17, and a locking rivet 18 is fixed laterally on the corresponding locking gate plate 19 on the right side of the first arm 7.

[0022] In addition, an angle is formed between the first support plate 3 and the first support arm 7, an angle is formed between the second support plate 4 and the second support arm 8, an angle is formed between the third support plate 5 and the third support arm 9, and an angle is formed between the fourth support plate 6 and the fourth support arm 10. The vertical projection of the locking gate 19 falls on the locking rivet 18.

[0023] During application, after the hoisting equipment is in place, use a lifting rope to fix it at the center of the supporting beam 2. At this time, the locking gate 19 is connected to the locking rivet 18, and the first arm 7, the second arm 8, the third arm 9 and the fourth arm 10 are in an open state. Then the drain pipe is located between the first arm 7 and the second arm 8, and between the third arm 9 and the fourth arm 10. After the drain pipe is in place, slightly press the supporting beam 2 downward to separate the locking gate 19 from the locking rivet 18, and rotate the locking gate 19 to dislocate the locking gate 19 from the locking rivet 18. At this time, the hoisting equipment is started to lift, and the supporting beam 2 rises. After the supporting beam 2 moves, the first support plate 3, the second support plate 4, the third support plate 5, the fourth support plate 6, the first arm 7, the second support plate The arm 8, the third arm 9 and the fourth arm 10 move synchronously, and the angles at all four sides increase. The bottom ends of the first arm 7 and the second arm 8, the third arm 9 and the fourth arm 10 are closed, and the clamping plate 11 is in contact with the drain pipe. As the supporting beam 2 continues to move upward, the clamping plate 11 can clamp the drain pipe. Then, under the action of the lifting equipment, the drain pipe is placed in the designated position. After the lifting equipment lowers the drain pipe, the angles at all four sides decrease, the first arm 7, the second arm 8, the third arm 9 and the fourth arm 10 are opened, and the clamping plate 11 is also separated from the drain pipe. At this time, the locking gate 19 is connected to the locking rivet 18, so that the first arm 7, the second arm 8, the third arm 9 and the fourth arm 10 are in an open state to facilitate the subsequent clamping of the drain pipe. Example 2:

[0024] The basic content of Example 1 is different in that:

[0025] See also Figure 1-2 In this embodiment, a lifting ear 1 is vertically fixed at the center of the outer side of the supporting beam 2, the clamping plate 11 is an arc-shaped plate, and an anti-slip pad 16 is fixed to the inner side of the clamping plate 11. The cross-sections of the first arm 7, the second arm 8, the third arm 9 and the fourth arm 10 are all arc-shaped, and a reinforcing rod is fixed between the first arm 7 and the third arm 9, and between the second arm 8 and the fourth arm 10.

[0026] When in use, during hoisting, it is convenient to hoist by connecting it to the lifting ear 1 through a hoisting rope or a buckle. During the clamping process, the anti-slip pad 16 located on the clamping plate 11 can make the clamping of the drain pipe more stable, and the reinforcing rod can also increase the firmness of the clamp. Example 3:

[0027] The basic content of Example 1 is different in that:

[0028] See also Figure 1 and Figure 4In this embodiment, a connecting plate 12 is fixed to the left side of the second arm 8, and the left side of the connecting plate 12 is slidably connected to the right side of the third arm 9. A side plate 13 is fixed to the front of the connecting plate 12, and the side plate 13 abuts against the right side of the third arm 9. An annular plate 15 is fixed at an angle on the end of the side plate 13 away from the connecting plate 12. A support rod 14 is transversely fixed to the left side of the first arm 7 by bolts, and the left end of the support rod 14 extends to the inside of the annular plate 15. The support rod 14 is slidably connected to the annular plate 15. The left end of the support rod 14 is slidably connected to the right side of the third arm 9. A baffle 20 is fixed to the outside of the support rod 14 and close to the annular plate 15. The baffle 20 is slidably connected to the right side of the annular plate 15.

[0029] When in use, during the clamping process, the first arm 7 and the second arm 8 rotate in opposite directions. When the first arm 7 moves, the support rod 14 will be driven to move. When the second arm 8 moves, the annular plate 15 will be driven to move through the connecting plate 12 and the side plate 13. At this time, the support rod 14 will also move inside the annular plate 15. Due to the limited internal space of the annular plate 15, when the support rod 14 moves inside the annular plate 15 until it cannot move, the first arm 7, the second arm 8, the third arm 9 and the fourth arm 10 cannot be opened or closed. With the cooperation of the annular plate 15 and the support rod 14, the opening and closing angles of the clamp can be controlled to improve practicality.

[0030] In addition, during use, lubricant needs to be applied to the right side of the third arm 9 to make the connecting plate 12, the side plate 13, the annular plate 15 and the support rod 14 slide more smoothly on the right side of the third arm 9.

[0031] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention.
