Description

Technical Field

[0001] The utility model relates to the technical field of construction, in particular to a socket steel ring supporting device. Background Art

[0002] Prestressed steel cylinder concrete pipe (hereinafter referred to as PCCP) refers to a water pipe made by winding annular prestressed steel wire on a high-strength concrete pipe core with a steel cylinder, and then spraying a dense cement mortar protective layer on it. It is a composite pipe composed of thin steel plate, high-strength steel wire and concrete. The socket steel ring is a specific pipe connection accessory designed to ensure the tightness and stability of the pipe connection. The socket steel ring is usually made of high-strength steel and has a ring-shaped structure. Its inner diameter usually matches the outer diameter of the pipe to ensure stable support and sealing when connected. Therefore, the socket steel ring needs to be expanded using an expansion machine to make it meet the requirements of the corresponding pipeline.

[0003] Some pipes have larger diameters, and their corresponding socket steel rings have larger diameters. The assembly and expansion processes are carried out in different locations. Therefore, after the socket is expanded, it needs to be transported to a specific location for assembly. However, the weight of the socket steel ring is large, which may cause part of the structure of the socket steel ring to sag during transportation and deform into an elliptical structure, making the socket steel ring not meet the requirements.

[0016] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0017] according to Figure 1-3 The utility model provides a socket steel ring supporting device, comprising: a supporting rod 1, a connecting plate 2, a lifting ear 3, and a limiting rod 4.

[0018] There are two support rods 1. The two support rods 1 are connected in the middle. The two support rods 1 are perpendicular to each other. A telescopic rod 11 is provided at one end of the support rod 1. The telescopic rod 11 can be telescopic relative to the support rod 1. The support rod 1 also includes: a rod body 12. The rod body 12 includes: a telescopic tube 121 and a short rod 122. There are several short rods 122. A screw is provided at one end of the short rod 122, and a screw hole is opened at the other end. The telescopic rod 11 extends into one end of the telescopic tube 121, and the other end of the telescopic tube 121 is connected to the short rod 122. A screw groove is opened on the inner side of one end of the telescopic tube 121 away from the short rod 122. The telescopic rod 11 corresponds to the screw groove. The end of the short rod 122 with the screw hole is farther away from the telescopic rod 11 than the end with the screw.

[0019] After the socket steel ring is expanded, the utility model is placed at the socket steel ring, so that one end of the two support rods 1 is in conflict with the socket steel ring, and the other end is the telescopic rod 11, which can be telescopic relative to the telescopic tube 121. Since the telescopic rod 11 corresponds to the screw groove in the telescopic tube 121, the telescopic rod 11 can be rotated to change the length of the telescopic rod 11 extending into the telescopic tube 121, that is, the overall length of the support rod 1 is changed. When the support rod 1 needs to play a supporting role, the length of the telescopic rod 11 extending into the telescopic tube 121 can be shortened first to facilitate insertion into the socket steel ring. In the subsequent process, after one end of the support rod 1 is in conflict with the socket steel ring, the other end can increase the length of the telescopic rod 11 extending into the telescopic tube 121, so that it is tightly pressed against the socket steel ring. By pressing the support rod 1 against the socket steel ring, the support rod 1 is fixed on the socket steel ring. At the same time, when the PCCP is transported, due to the supporting effect of the support rod 1, the socket steel ring cannot sag and cause deformation.

[0020] The telescopic rod 11 can change its length, but the length of change is limited. The support rod 1 of the utility model includes a telescopic rod 11 and a rod body 12. The rod body 12 can be divided into a telescopic tube 121 and a plurality of short rods 122. One end of the short rod 122 is a screw and the other end is a screw hole, so that the short rods 122 can be connected to each other. When the diameters of the socket steel rings to be supported are different, the number of short rods 122 can be changed accordingly so that most socket steel rings can be supported. One end of the screw hole of the short rod 122 is farther away from the telescopic rod 11 than one end of the screw, that is, for the short rod 122 farthest from the telescopic rod 11, its end away from the telescopic rod 11 is a screw hole, so as to avoid the screw of the thinner short rod 122 from colliding with the socket steel ring and causing the socket steel ring to be damaged.

[0021] The telescopic rod 11 includes a screw rod 111, a nut 112, and an extension rod 113. The screw rod 111 corresponds to the screw groove of the telescopic cylinder 121. The nut 112 corresponds to the screw rod 111. The extension rod 113 passes through one side of the nut 112. The direction from one end of the extension rod 113 to the other end is parallel to the end of the nut 112 away from the short rod 122.

[0022] The extension and retraction of the telescopic rod 11 is achieved by the screw 111. However, after the screw 111 extends into a part of the telescopic tube 121, the resistance encountered by manual further rotation of the screw 111 is relatively large. The nut 112 of the utility model corresponds to the screw 111, and the nut 112 can be sleeved on the screw 111, and then the extension rod 113 is rotated along the rotation direction of the nut 112 on the screw 111. By rotating the extension rod 113, the nut 112 can be driven to rotate, and then the screw 111 can be driven to rotate. Due to the lever principle, compared with directly rotating the screw 111, rotating the extension rod 113 is more labor-saving, that is, it is more labor-saving when adjusting the length of the telescopic rod 11.

[0023] A limiting opening 1211 is formed on the side of one end of the telescopic cylinder 121 away from the short rod 122. The limiting rod 4 can extend into the limiting opening 1211.

[0024] When adjusting the length of the telescopic rod 11, the screw 111 needs to be rotated. The screw groove of the telescopic tube 121 corresponds to the screw 111, and there is a certain friction between the screw 111 and the screw groove of the telescopic tube 121. When the screw 111 extends into the telescopic tube 121 for a long time, the contact area between the screw 111 and the screw groove is also large, which makes the friction larger. If the screw 111 rotates at this time, it is easy to drive the telescopic tube 121 to rotate together through this friction. The telescopic tube 121 then causes other structures of the support rod 1 to twist and move, etc., so that the supporting position of the support rod 1 changes, resulting in the inability to support the socket steel ring well. Therefore, when adjusting the length of the telescopic rod 11, the support rod 1 needs to be held, but the support rod 1 is usually round for the convenience of manufacturing. Even if a large force is used to hold it, The friction between the support rod 1 and the hand is also small, making it difficult to manually control the support rod 1 to prevent it from rotating. The utility model opens a limit opening 1211 on the telescopic cylinder 121. When the length of the telescopic rod 11 needs to be adjusted, the limit rod 4 can be inserted into the limit opening 1211 and the limit rod 4 can be manually held. When the telescopic cylinder 121 wants to rotate, it will conflict with the limit rod 4, making it difficult to rotate. When the telescopic cylinder 121 wants to rotate, the force between the limit rod 4 and the telescopic cylinder 121, and the force between the limit rod 4 and the human hand are both squeezing forces. Compared with directly holding the support rod 1, this can make it easier to control the support rod 1. At the same time, the limit rod 4 can also act as a lever, which can prevent the support rod 1 from rotating with less force.

[0025] The connecting plate 2 is arranged at the connection of the two supporting rods 1. The lifting lug 3 is arranged on the side of the connecting plate 2 away from the supporting rod 1.

[0026] A connecting plate is provided at the connection of the two support rods 1 to further strengthen the connection between the two support rods 1. When the support rods 1 need to be moved, tools such as a crane will be used, and the lifting lugs 3 are convenient for lifting the support rods 1.

[0027] The working principle and use process of this utility model:

[0028] When the utility model needs to be used, the screw rod 111 is rotated so that the screw rod 111 extends into the telescopic tube 121 for a certain distance, and then a crane is used to lift it to the socket steel ring through the lifting ear 3, and then the ends of the two support rods 1 without the telescopic rod 11 are manually made to conflict with the inner surface of the socket steel ring, and the positions of the support rods 1 are adjusted so that the planes where the two support rods 1 are located are parallel to the plane where the mouth of the socket steel ring is located, and then the limit rod 4 is held, and the extension rod 113 is rotated to drive the nut 112 to rotate. The nut 112 drives the screw 111 to rotate, so that the screw 111 moves away from the short rod 122, and conflicts with the inner surface of the socket steel ring and is tightened, so that the support rod 1 supports the socket steel ring of the column.

[0029] In summary, the utility model is provided with two support rods, and a telescopic rod is provided on the support rod, so that one end of the support rod can be in contact with the inner surface of the socket steel ring, and the other end can change its length through the telescopic rod and be in contact with the inner surface of the socket steel ring to tighten, so that the support device can be fixed on the socket steel ring and support the socket steel ring at the same time, avoiding the sagging deformation problem of the socket steel ring during the transportation of the PCCP steel cylinder.
