Description

Technical Field

[0001] This utility model relates to an auxiliary installation platform for socket joint corner testing, which is particularly suitable for joint corner testing of PCCP standard pipes, reinforced concrete drainage pipes, underground integrated pipe corridors, culverts and various concrete components with sockets and spigots, and can facilitate the connection and cornering of socket joints of concrete components. Background Technology

[0002] In China, concrete components with spigot and socket joints, especially PCCP standard pipes, reinforced concrete drainage pipes, underground integrated pipe corridors, and culverts, need to undergo spigot and socket joint rotation tests before leaving the factory. This test, also known as type inspection, is used to verify whether the performance indicators of precast concrete components meet the design requirements. Only components that meet the test conditions can be delivered for use.

[0003] Currently, the common practice for testing the rotation angle of spigot and socket joints in concrete components is to use a gantry crane to hoist the components to be connected into position, and then perform the connection installation while still suspended. During installation, sleepers are installed at both ends of both the components to be connected and the connecting components, serving as crossbeams. Chains are installed at both ends of the sleeper crossbeams, and a hand-operated hoist pulls the two sleeper crossbeams closer together, causing the crossbeams to drive the two connecting components to complete the connection installation. However, leveling the connecting components in the air during the installation process is extremely difficult, and the movement of the gantry crane is hard to control. Even slight exertion can damage the spigot and socket joints of the components, requiring replacement and resulting in significant waste. Furthermore, the entire connection installation process is done manually by pulling the chain hoist, which is time-consuming, labor-intensive, and carries significant safety risks. If the components are heavy, the required pulling force is large, increasing the risk of chain breakage during operation. Utility Model Content

[0004] The purpose of this utility model is to design an auxiliary installation platform for corner testing of socket joints, which can reduce the number of personnel required when connecting concrete components with sockets and spigots, reduce personnel safety risks, improve the installation efficiency of horizontal connection of concrete components with sockets and spigots, and ensure that the socket joints are not damaged during connection installation.

[0005] Based on this objective, after repeated design and research, we have developed an auxiliary installation platform for socket joint corner testing. Its basic principle is to set up two movable balance vehicles, one of which serves as a load-bearing and fixing vehicle, and the other serves as a docking vehicle, and can achieve small-range adjustment in the up-down and left-right directions.

[0006] The basic structure of an auxiliary installation platform for a socket joint corner test consists of a four-wheel walking mechanism (1), a translation support frame (2), a docking support frame (3), a limiting column (4), a telescopic cylinder (5), a limiting block (6), a fixing bolt (7), a lifting cylinder (8), an oil pipe (9), a hydraulic adjustment station (10), a rotating shaft (11), a translation bearing (12), a reinforcing liner (13), a horizontal adjustment rod (14), and a track (15). There is a horizontal height difference between the translation support frame (2) and the docking support frame (3), with the translation support frame (2) being higher than the docking support frame (3). 3) The horizontal height difference between the two can be adjusted by the lifting cylinder (10) to achieve the same horizontal height. The track (15) is laid on the ground so that the four-wheel walking mechanism (1) can walk and move on it. The four-wheel walking mechanism (1) is installed at the bottom of the translation support frame (2) and the docking support frame (3) respectively, which can drive the translation support frame (2) and the docking support frame (3) to move on the track (15). The limiting column (4) is installed at both ends of the translation support frame (2) and the docking support frame (3) respectively to limit and fix the docking object. The telescopic cylinder (5) is installed on both ends of the translation support frame (2). On the side, the telescopic rod of the telescopic cylinder (5) can extend and retract freely. The limit stop (6) is installed on both sides of the docking support frame (3). After the horizontal height difference between the translation support frame (2) and the docking support frame (3) is adjusted, the telescopic rod of the telescopic cylinder (5) can pass through the limit stop (6) and be locked by the fixing bolt (7). Thus, under the action of the telescopic cylinder (5), the translation support frame (2) and the docking support frame (3) can be pulled closer or driven away. The lifting cylinder (8) is installed on both sides of the docking support frame (3) and can support the docking support frame (3). The oil pipe (9) connects the telescopic cylinder (5) to the telescopic cylinder (5) respectively. The telescopic cylinder (5) and the lifting cylinder (8) are connected to the hydraulic adjustment station (10). The telescopic cylinder (5) and the lifting cylinder (8) can be controlled by the hydraulic adjustment station (10). The rotating shaft (11) is mounted in the docking support frame (3) to form a support plane. The translation bearing (12) is mounted on the rotating shaft (11). The reinforcing liner (13) is placed on the support plane formed by the rotating shaft (11) and the translation bearing (12). The horizontal adjustment rod (14) is installed on both sides of the docking support frame (3). The reinforcing liner (13) can be adjusted left and right by adjusting the horizontal adjustment rod (14).

[0007] This invention can reduce the number of personnel required for connecting concrete components with sockets and spigots, reduce personnel safety risks, effectively improve the installation efficiency of horizontally connecting concrete components with sockets and spigots, and ensure that the socket and spigot joints are not damaged during the connection and installation process.

[0009] Appendix Figure 2 This is a partial top view of the present invention, which consists of a docking support frame (3), a limiting block (6), a lifting cylinder (8), a rotating shaft (11), a translation bearing (12), and a horizontal adjusting rod (14). Detailed Implementation

[0010] First, place the concrete components with bearings and sockets that need to be installed on the translation support frame (2) and the docking support frame (3), respectively. The installation component is placed on the translation support frame (2), and the component to be installed is placed on the docking support frame (3). Since the track (15) is laid on the ground, the four-wheel walking mechanism (1) can move on it. Since the four-wheel walking mechanism (1) is installed at the bottom of the translation support frame (2) and the docking support frame (3), it can drive the translation support frame (2) and the docking support frame (3) to move on the track (15). Since the oil pipe (9) connects the telescopic cylinder (5) and the lifting cylinder (8) to the hydraulic adjustment station (10), the telescopic cylinder (5) and the lifting cylinder (8) can be controlled by the hydraulic adjustment station (10). The extension and lifting of the cylinder (8) are controlled by the hydraulic adjustment station (10) to raise the lifting cylinder (8). When the installation part and the installed part are at the same horizontal height, the hydraulic adjustment station (10) is locked. Because the limit block (6) is installed on both sides of the docking support frame (3), after the horizontal height difference between the translation support frame (2) and the docking support frame (3) is adjusted, the extension rod of the extension cylinder (5) can pass through the limit block (6) and be locked by the fixing bolt (7). Thus, under the action of the extension cylinder (5), the translation support frame (2) and the docking support frame (3) can be pulled closer or driven away. Therefore, the hydraulic adjustment station (10) is adjusted to make the extension rod of the extension cylinder (5) extend through the limit block (6) and be locked by the fixing bolt (7). Then the hydraulic adjustment station (10) is adjusted again. The telescopic cylinder (5) retracts its telescopic rod, thus gradually closing the distance between the translation support frame (2) and the docking support frame (3). The rotating shaft (11) is mounted inside the docking support frame (3) to form a support plane. The translation bearing (12) is mounted on the rotating shaft (11), and the reinforcing liner (13) is placed on the support plane formed by the rotating shaft (11) and the translation bearing (12). The horizontal adjustment rod (14) is installed on both sides of the docking support frame (3). By adjusting the horizontal adjustment rod (14), the reinforcing liner (13) can be adjusted left and right. Therefore, during the docking process of the translation support frame (2) and the docking support frame (3), if obstruction is encountered, the left and right positions of the parts installed on the reinforcing liner (13) can be adjusted using the horizontal adjustment rod (14). After the adjustment is completed and the spigot and socket are aligned without any misalignment, continue to retract the telescopic cylinder (5) to complete the installation of the concrete components of the spigot and socket. After installation, adjust the hydraulic adjustment station (10) to raise the lifting cylinder (8) again, so that the installation part and the installed part form a joint angle. Then, conduct a test. After the test, adjust the hydraulic adjustment station (10) to retract the telescopic cylinder (5) to the docking installation position. Continue to adjust the hydraulic adjustment station (10) to extend the telescopic cylinder (5) to separate the translation support frame (2) and the docking support frame (3). Loosen the fixing bolts (7) and retract the telescopic cylinder (5). Then, lift the installation part and the installed part away. Then, adjust the hydraulic adjustment station (10) to retract the lifting cylinder (8).The support frame (3) returns to its initial position, concluding this test of the rotation angle of the concrete components at the spigot and socket joints.
