Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without any inventive step, are within the scope of the present invention.
As shown in fig. 2 to 5, the present invention provides an embodiment of an angle adjuster for a bridge pushing device, comprising a base 201 capable of connecting with the top of a jack 101 of the pushing device, a cylinder 202 disposed on the upper surface of the base 201, a concave groove 203 opened on the top of the cylinder 202,
the depressed groove 203 includes sphere downward hemisphere recess and the cylindrical recess that is linked together with hemisphere recess, be equipped with the hemisphere 204 with hemisphere recess looks adaptation in the depressed groove 203, hemisphere 204 can be universal rotation in depressed groove 203, and the plane one end of hemisphere 204 is equipped with the bracing piece 205 that stretches out cylinder body 202, there is the interval between the pole wall of bracing piece 205 and the cylindrical recess, and the bracing piece 205 one end that stretches out cylinder body 202 is equipped with supporting roof 206.
When the semi-sphere 204 is used, lubricating oil is uniformly coated in the concave groove 203 for facilitating the rotation of the semi-sphere 204. In addition, the outer surface of the regulator can be sprayed with antirust paint.
In specific implementation, as shown in fig. 1, the base 201 of the adjuster is fixed to the jack 101 of the pushing device, the smoothness of the movement of the hemisphere 204 is checked, and a proper amount of lubricating oil is filled in the gap between the supporting rod 205 and the cylinder 202 and is rotated back and forth for several times to lubricate between the hemisphere 204 and the concave groove 203. Respectively placing the pad beams 3 on the top of the support column 102 of the pushing equipment and the support top plate 206 of the adjuster, and hoisting the beam body 4 after the pad beams 3 are placed. In the continuous pushing process of the bridge, as the hemispheroid 204 can universally rotate in the concave groove 203, the center line of the supporting rod 205 can deflect relative to the center line of the cylindrical groove in the vertical direction, and the upper surface of the supporting top plate 206 automatically deflects to adjust the angle according to the line shape of the beam body 4, so that the included angle between the pushing equipment and the beam body 4 is adjusted to achieve reasonable stress; in the continuous pushing process of the bridge, when the beam body 4 is horizontally corrected, the hemisphere 204 can horizontally rotate in the concave groove 203, so that the supporting top plate 206 horizontally rotates according to the rotation angle of the beam body 4, and the bridge is convenient to correct.
In the present invention, the rotation of the hemisphere 204 in the vertical direction relative to the concave groove 203 is limited by the gap between the support rod 205 and the concave groove 203, and the rotation of the hemisphere 204 in the horizontal direction relative to the concave groove 203 is not limited.
Specifically, as shown in fig. 4, the center of the hemispherical recess is located on the center line of the cylindrical recess, and the diameter of the cylindrical recess is equal to that of the hemispherical recess.
When the support rod is used specifically, in order to enable the hemisphere 204 to rotate uniformly in all directions in the concave groove 203, the support rod 205 is of a cylindrical rod structure, and the center of the hemisphere 204 is located on the central line of the support rod 205.
Further, the rotating hemisphere 204 can deflect the centerline of the support rod 205 a maximum of 4.5 ° relative to the centerline of the cylindrical recess. Practical tests show that the maximum deflection is 4.5 degrees, and the advancing direction of the bridge curve is consistent with the axis of the bridge when the bridge curve is pushed.
The invention further provides a connection mode between the base 201 and the jack 101, namely, the base 201 is provided with a clamping groove 207 which is clamped and matched with the top of the jack 101. The size of the clamping groove 207 is processed according to the size of the top of the jack 101, and in order to ensure that the clamping groove can be sleeved in the top of the jack 101 and to enable the base 201 to be firmly sleeved, the clamping groove 207 is 1mm larger than the top of the jack 101. Before the regulator is used, the clamping groove 207 needs to be cleaned.
Specifically, the base 201 and the cylinder 202 are integrally cast from Q355 steel, and the hemisphere 204, the support rod 205 and the support top plate 206 are integrally cast from Q355 steel.
On the basis of not influencing the bridge construction, the invention effectively improves the construction efficiency through the angle regulator, and simultaneously guarantees the stress, the safety and the construction quality of the bridge.
