Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bridge construction, in particular to an integral ball joint quality control device for a swivel bridge. Background Art
[0002] In recent years, my country's highways have developed rapidly, and there are more and more long bridge projects. The construction across existing railway lines has increased year by year. When choosing the form of bridges across existing railway lines, various railway bureaus give priority to the rotation construction method that has less impact on the safety of existing lines. By setting a rotation ball joint between the upper and lower turntables, it plays a role in rotation support. The cast-in-place bridge is first cast on both sides of the railway line, and the bridge is pulled and rotated into place by traction equipment to cross the existing railway line. The ball joint installation requires high precision. If the bottom concrete is not dense, it is easy to cause bottom cavities. When rotating, the bottom friction is insufficient, resulting in deformation of the ball joint. Therefore, the installation quality of the ball joint is very important and directly related to whether the rotation can be successful. Utility Model Content
[0003] The utility model aims to provide a swivel bridge integral ball joint quality control device to solve the problems raised in the above-mentioned background technology and ensure the installation quality of the ball joint.
[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0005] A quality control device for an integral ball joint of a swivel bridge, wherein a circular outer mold is installed on the outer side of a ball joint leveling layer, the outer mold is formed by bending and welding a stainless steel template, the outer mold fits the lower plate of the ball joint, four leveling bolts and locating holes are arranged around the outer mold, the leveling bolts support the upper and lower plate locking devices of the integral ball joint, and a leveling nut is arranged on the leveling bolt; epoxy resin mortar is poured under the ball joint, and grouting holes and grouting pipes are arranged around the outer mold.
[0006] As a further solution of the utility model: the number of the grouting holes is four.
[0007] Compared with the prior art, the beneficial effects of the utility model are: the utility model has a stable structure, is safe and reliable to use, has a short processing and installation period, is economical and practical, and is easy to construct and operate, thereby ensuring the installation accuracy of the ball joint and the density of the bottom concrete, greatly improving the installation quality of the ball joint of the swivel bridge, and having high practicality. BRIEF DESCRIPTION OF THE DRAWINGS
[0008] Figure 1 It is a plan view of the utility model.
[0009] Figure 2 It is a large-scale drawing of the leveling bolt in the utility model.
[0010] Among them: 1 outer mold, 2 positioning holes, 3 leveling bolts, 4 grouting pipes, 5 leveling nuts. DETAILED DESCRIPTION
[0011] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.
[0012] See also Figure 1-2 The utility model provides a quality control device for an integral ball joint of a swivel bridge. A circular outer mold 1 is installed outside the ball joint leveling layer. The outer mold 1 is formed by bending and welding a stainless steel template. The outer mold 1 fits the lower plate of the ball joint. Four leveling bolts 3 and positioning holes 2 are arranged around the outer mold 1. The leveling bolts 3 support the locking device of the upper and lower plates of the integral ball joint. The leveling nuts 5 are arranged on the leveling bolts 3. Epoxy resin mortar is poured under the ball joint. Grouting holes and grouting pipes 4 are arranged around the outer mold 1. The number of the grouting holes is four.
[0013] By cross-centering the outer mold 1, the center line of the device is aligned with the center line of the ball joint, and after the center of the device is positioned, the plane position of the device is fixed through the positioning port 2.
[0014] To ensure the installation accuracy of the ball joint, the ball joint is hoisted into place, the leveling bolt 3 is pressed against the upper and lower plate locking device of the integral ball joint, and precise leveling is performed by rotating the leveling nut 5 to ensure the flatness requirement of the ball joint.
[0015] After the flatness and center position of the ball joint are determined, the ball joint is temporarily hoisted, epoxy resin mortar is poured, and then the ball joint is lowered. The mortar is squeezed out by gravity, and gravity grouting is used to ensure the density of the bottom of the ball joint. In order to further ensure the density of the bottom of the ball joint and reduce bubbles, four grouting holes are arranged around the device, and grouting is performed from the center of the ball joint to the surrounding areas. Grouting is injected through the grouting pipe 4 to squeeze out the bubbles from the center of the ball joint.
[0016] The preferred implementation modes of the present application are described in detail above, but the present application is not limited to the above implementation modes, and various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present application.
