Description

Technical Field

[0001] The utility model belongs to the field of construction engineering, and particularly relates to a rubber ring installation device for reinforced concrete drainage pipes. Background Technique

[0002] Reinforced concrete drainage pipes are widely used in municipal drainage projects. Rubber rings are provided at the joints of socket pipes for interface sealing. These rubber rings can ensure good sealing performance at the joints of pipes. The correct installation method of the rubber ring can ensure that the joints of the pipes are both firm and sealed, which is not only related to the service life of the pipes, but also related to their safety and reliability. However, due to the requirement that the rubber ring needs to be closely attached to the outside of the pipe socket, the inner diameter of the rubber ring is generally smaller than the outer diameter of the pipe socket, resulting in difficult installation and low efficiency of the rubber ring. Summary of the Invention

[0003] The problem to be solved by the present invention is to overcome the deficiencies of the background technique and provide a rubber ring installation device for reinforced concrete drainage pipes.

[0004] The present invention is achieved through the following technical solutions:

[0005] A rubber ring installation device for reinforced concrete drainage pipes includes an annular steel sleeve, and a conical steel ring is integrally connected to the rear of the annular steel sleeve. The diameter of the conical steel ring gradually decreases backward. An annular groove is provided on the front end face of the annular steel sleeve. The width of the annular groove is equal to the thickness of the pipe socket of the drainage pipe, and the depth of the annular groove is less than the length of the pipe socket of the drainage pipe. It also includes a rectangular support frame. The front ends of the four horizontal support rods of the rectangular support frame are respectively fixedly connected to the rear end faces of two symmetrical semi-circular steel rings. The two semi-circular steel rings are combined to form a ring. The inner diameter of the semi-circular steel ring is larger than the minimum diameter of the conical steel ring and smaller than the maximum diameter of the conical steel ring. The front end face of the semi-circular steel ring is an inward concave arc surface, and the support rods are elastic.

[0006] Preferably, the length of the conical steel ring is 10 - 20 cm.

Specific implementation method

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention.

[0019] The rubber ring installation device for the reinforced concrete drain pipe in this embodiment includes an annular steel sleeve 3. An annular groove 5 is provided on the front end surface of the annular steel sleeve 3. The annular steel sleeve 3 is used to clamp the socket 2 of the drain pipe 1. Therefore, the width of the annular groove 5 is equal to the thickness of the socket 2 of the drain pipe 1, that is, the opening of the annular groove 5 can just clamp the socket 2, and the cross-section of the annular groove 5 is U-shaped. The depth of the annular groove 5 should be less than the length of the socket 2 of the drain pipe 1, that is, the length of the annular groove 5 that can clamp the socket 2 should be less than the total length of the socket 2. The depth of the annular groove 5 here refers to the horizontal length of the annular groove 5.

[0020] The annular steel sleeve 3 is integrally connected to the frustum-shaped steel ring 4 at the back. The diameter of the frustum-shaped steel ring 4 gradually decreases backward. Preferably, the length of the frustum-shaped steel ring 4 is 10-20 cm. The frustum-shaped steel ring 4 is used for temporarily sleeving the rubber ring, and then the rubber ring is gradually pushed onto the annular steel sleeve 3 through the frustum-shaped steel ring 4.

[0021] The device further includes a rectangular support frame 6, which includes four horizontal support rods 7. The front ends of the four support rods 7 are respectively fixedly connected to the rear end faces of two symmetric semi-circular steel rings 8. That is, two support rods 7 are fixed on one semi-circular steel ring 8, and the other two symmetric support rods 7 are fixed on the other semi-circular steel ring 8. After the two semi-circular steel rings 8 are combined, a circular ring can be formed, and the inner diameter of the semi-circular steel ring 8 is larger than the minimum diameter of the frustum-shaped steel ring 4 and smaller than the maximum diameter of the frustum-shaped steel ring 4. That is, the circular ring formed after the two semi-circular steel rings 8 are combined can be sleeved on the middle position of the frustum-shaped steel ring 4. In addition, the four support rods 7 are elastic, that is, the front part of the support rod 7 can be slightly bent outward under the action of an external force. After the external force disappears, the support rod 7 can return to its original state. In this way, when the rectangular support frame 6 is pushed forward forcefully, the support rod 7 can be bent outward under the action of the external force, so that the two semi-circular steel rings 8 are separated, so that the two semi-circular steel rings 8 can continue to slide along the frustum-shaped steel ring 4 until they reach the annular steel sleeve 3 with an inner diameter larger than that of the semi-circular steel ring 8. The front end face of the above semi-circular steel ring 8 is an inwardly concave arc surface 9, and the inwardly concave arc surface 9 is used to push the rubber ring sleeved on the frustum-shaped steel ring 4 forward. The design of the inwardly concave arc surface 9 can also block the rubber ring.

[0022] Construction process: First, insert the socket 2 of the drain pipe 1 into the annular groove 5 of the annular steel sleeve 3, then put the rubber ring on the middle position of the frustum-shaped steel ring 4. The worker pushes the rectangular support frame 6 from the rear of the rectangular support frame 6. The two semi-circular steel rings 8 at the front end of the rectangular support frame 6 are sleeved on the frustum-shaped steel ring 4. As the rectangular support frame 6 is pushed forward, the inwardly concave arc surface 9 of the semi-circular steel ring 8 begins to contact the rubber ring on the frustum-shaped steel ring 4 and pushes the rubber ring forward. As it is pushed forward, the support rod 7 bends slightly outward, and the two semi-circular steel rings 8 are slightly separated outward, so that the two inwardly concave arc surfaces 9 of the two semi-circular steel rings 8 can continue to push the rubber ring forward along the frustum-shaped steel ring 4 until the rubber ring is pushed to the designed position of the rubber ring of the socket 2. Then, the annular steel sleeve 3, the frustum-shaped steel ring 4, the semi-circular steel ring 8 and the rectangular support frame 6 can be taken out.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them; those of ordinary skill in the art should understand that they can still modify the technical solutions described in the above embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
