Description

Technical Field

[0001] The utility model relates to the technical field of manufacturing of connecting pipes, in particular to a support ring for manufacturing connecting pipes. Background Art

[0002] Connecting pipes are mainly used in urban sewage discharge, agricultural irrigation, and drainage systems. During installation, it is convenient to install seals at the head and tail, with simple installation, good sealing performance, good economic benefits, convenient construction, reliability, and speed. They can be quickly transported to the designated location according to the construction situation. Therefore, concrete connecting pipes are important basic materials in drainage construction.

[0003] When manufacturing small-diameter double rubber ring jacking pipes with a core mold vibration process, especially for pipes with a diameter of DN1500 and below, due to the fact that the fitting clearance between the socket and spigot is only 4 mm, the self-weight of small-diameter pipes is light, and it is not smooth to extract the socket support ring. The support ring is not easy to fall off, and there are situations such as pipe inclination and collision, which prolongs the production time. For this reason, we propose a support ring for manufacturing connecting pipes to solve the above problems. Summary of the Utility Model

[0004] This application provides a support ring for manufacturing connecting pipes, which solves the problems that the support ring is not easy to fall off during the manufacturing process of connecting pipes, resulting in low ring removal efficiency and easy collision.

[0005] This application provides a support ring for manufacturing connecting pipes, including a support ring. On both sides of one end of the support ring, there are brackets, and a telescopic jacking rod is detachably arranged on the brackets, and a gasket is arranged at the end of the telescopic jacking rod.

[0006] Preferably, the bracket includes a support installed on the support ring, and a detaching ear is fixed on one side of the support, and the telescopic jacking rod is detachably installed on the detaching ear.

[0007] Preferably, a limiting groove is arranged in the detaching ear, and a limiting plate corresponding to the limiting groove is installed at the bottom of the telescopic jacking rod.

[0008] Preferably, a threaded hole is arranged at the top of the detaching ear, and a limiting screw is arranged in the threaded hole, and the limiting screw extends into the limiting groove.

[0009] Preferably, a cross bar is fixed between the two detaching ears.

[0010] Preferably, a second lifting ear is installed on the cross bar.

[0011] Preferably, the telescopic jacking rod is a jack.

[0012] Preferably, three first lifting ears are equidistantly installed on the support ring.

[0013] Preferably, the gasket is threadedly sleeved on the end of the telescopic jacking rod.

[0014] It can be seen from the above technical scheme that the present application provides a support ring for the production of a receiving tube. The present application is used normally during the production of the receiving tube. When demolding is required, the telescopic push rod is installed on the brackets on both sides of the support ring, and the telescopic push rod is adjusted so that the gasket is in contact with the edge of the receiving tube. Then, the support ring is pushed out of the formed receiving tube by adjusting the telescopic push rod. During disassembly, if the gasket sinks, it is necessary to stop immediately, retract the telescopic push rod, and pad it with a larger gasket again to prevent the pipe mouth of the receiving tube from being squeezed and deformed and affecting subsequent installation. After removing the receiving tube, the support ring can be directly connected to the telescopic push rod to remove it, or the support ring can be removed after the telescopic push rod is removed. The process of removing the support ring is simple and efficient.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. Through the cooperation of the bracket and the telescopic ejector rod, the pipe mouth of the receiving pipe can be used as a support, and the support ring can be ejected using the telescopic ejector rod and the bracket. The ring removal process is simple and efficient, and no collision occurs during the ring removal process, thereby improving the ring removal efficiency;

[0017] 2. By setting the gasket, the pipe mouth position of the socket can be effectively protected, which can not only protect the smooth appearance of the end of the socket, but also prevent the pipe mouth from deformation, thus not affecting the subsequent socket assembly.

[0018] To sum up, the present application improves the work efficiency during ring removal through the improvement of the support ring, and will not cause any impact on the receiving tube. Therefore, in the preparation process of the receiving tube, the collision and low efficiency caused by ring removal can be effectively reduced, and it is suitable for the manufacture of small-diameter receiving tubes of DN1500 and below.

[0019] In order to more clearly illustrate the technical solution of the present application, the following is a brief introduction to the drawings required for use in the implementation cases. Obviously, for ordinary technicians in this field, other drawings can be obtained based on these drawings without any creative work.

[0025] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings.

[0026] See Figures 1-4 , a support ring for the production of a receiving pipe. The receiving pipe is formed by inserting a beam into a precast concrete pipe, and the two ends are respectively a socket and a spigot. During installation, the spigot is inserted into the socket to form a sealed connection pipe. The socket is formed by installing the support ring 1 at one end of the beam. Usually, when removing the ring, the support ring 1 is directly removed by pulling force. However, for small-diameter receiving pipes, due to the small inner diameter and light pipe quality, during the process of removing the ring, it is easy to cause the pipe to tilt and collide. Therefore, the original support ring 1 needs to be modified. Specifically, it includes the support ring 1. On both sides of one end of the support ring 1, there are brackets 12. The brackets 12 extend to both sides of the support ring 1. A telescopic ejector rod 10 is detachably arranged on the brackets 12. When the telescopic ejector rod 10 extends downward, it abuts against the receiving pipe on both sides of the support ring 1. By adjusting the telescopic ejector rod 10, the support ring 1 is removed from the receiving pipe. The telescopic ejector rod 10 is only installed on the bracket 12 during the process of removing the ring. During the process of transporting the support ring 1 during the production of the receiving pipe, the telescopic ejector rod 10 is removed without affecting the normal production and transportation links. Therefore, it will not affect the use of the support ring 1. A gasket 11 is arranged at the end of the telescopic ejector rod 10. In this application, the gasket 11 is threadedly sleeved on the end of the telescopic ejector rod 10 and can be replaced according to different usage situations. The gasket 11 mainly protects the quality of the end face of the receiving pipe and also avoids deformation of the socket position of the receiving pipe caused by extrusion. Through the setting of this application, after the operation, the removal of the support ring 1 of a receiving pipe can be completed within 1-5 minutes. It should be understood that the influence of the time difference lies in that for the removal of the support ring 1 with a smaller diameter, after the support ring 1 is separated, the worker can directly remove the support ring manually. When removing the support ring 1 with a diameter of DN1500 - DN1000, a crane is needed to remove the support ring 1, so the time consumption is different.

[0027] In the present utility model, the bracket 12 includes a bracket 7 mounted on the support ring 1. The bracket 7 is an I-beam welded to the end face of the support ring 1. One side of the bracket 7 is fixed with a lifting lug 3. The lifting lug 3 is formed by welding two 1 / 4 circular steel plates on the bracket 7. A steel plate is welded above the two 1 / 4 circular steel plates to form the lifting lug 3. The telescopic ejector rod 10 is detachably mounted on the lifting lug 3. The lifting lug 3 can form a stable support for the telescopic ejector rod 10, and the bracket 12 with small deformation can be used until the support ring 1 is damaged.

[0028] In the present utility model, a limiting groove 8 is provided in the lifting lug 3. The limiting groove 8 is a T-shaped groove formed by welding two steel plates on the inner wall of the lifting lug 3. A limiting plate 9 corresponding to the limiting groove 8 is installed at the bottom of the telescopic ejector rod 10. During installation, the limiting plate 9 is inserted into the limiting groove 8, which can prevent the telescopic ejector rod 10 from falling off the lifting lug 3 due to lack of pre-tightening force after the support ring 1 is ejected.

[0029] In the present utility model, when it is necessary to remove the support ring 1 and the telescopic ejector rod 10 together from the receiving pipe, in order to prevent the telescopic ejector rod 10 from detaching, a threaded hole is provided at the top of the lifting lug 3, and a limiting screw 6 is provided in the threaded hole. The limiting screw 6 extends into the limiting groove 8. After the telescopic ejector rod 10 is installed on the limiting groove 8, the limiting screw 6 is screwed into the limiting groove 8, which can prevent the limiting plate 9 from sliding out of the limiting groove 8, playing a role in restricting the telescopic ejector rod 10. After the telescopic ejector rod 10 is installed, it can move together with the support ring 1.

[0030] In the present utility model, a cross bar 2 is fixed between the two lifting lugs 3. The setting of the cross bar 2 can effectively reduce the force on the two brackets 7 when the telescopic ejector rod 10 ejects the support ring 1, and the force bending towards the inner side of the support ring 1, thereby avoiding the deformation of the support ring 1 caused by the bending of the bracket 7. A second lifting lug 5 is installed on the cross bar 2, and the support ring 1 can also be carried through the second lifting lug 5.

[0031] In the present utility model, since the scope of application of this application is large, there are production sites both indoors and outdoors, and in order to improve the flexibility of use, the telescopic ejector rod 10 is a jack, which can be adjusted manually, saving time and effort, and can be used arbitrarily in the factory area.

[0032] In the present utility model, three first lifting lugs 4 are equidistantly installed on the support ring 1. During the process of carrying and installing the support ring 1, it is necessary to hang the three first lifting lugs 4 to ensure the stability of the support ring 1, so as to facilitate the assembly of the support ring 1 during production.

[0033] It can be seen from the above technical scheme that the present application is used normally during the production of receiving tubes. When demoulding is required, the telescopic push rod 10 is installed on the brackets 12 on both sides of the support ring 1, and the telescopic push rod 10 is adjusted so that the gasket 11 contacts the edge of the receiving tube, and then the support ring 1 is pushed out from the formed receiving tube by adjusting the telescopic push rod 10. During disassembly, if the gasket 11 sinks, it is necessary to stop immediately, retract the telescopic push rod 10, and pad it with a larger gasket 11 again to prevent the receiving tube mouth from being squeezed and deformed and affecting subsequent installation. After removing the receiving tube, the support ring 1 can be removed together with the telescopic push rod 10, or the support ring 1 can be removed after the telescopic rod 10 is removed. The process of removing the support ring 1 is simple and efficient.
