Description

Technical Field

[0001] This utility model relates to the field of bridge bearing installation technology, specifically a bridge bearing installation auxiliary device. Background Technology

[0002] With the continuous expansion of bridge construction scale and the increasing complexity of structural forms, bridge bearings play a crucial role in bridge engineering. As a key force transmission component connecting the upper beam and lower pier of a bridge, the installation accuracy and efficiency of bridge bearings have a direct and far-reaching impact on the safety, durability and operational stability of the entire bridge. Bearings not only have to withstand huge loads, but also adapt to the influence of various complex factors such as temperature changes and seismic action. Therefore, the quality of their installation is directly related to the service life of the bridge and traffic safety.

[0003] Currently, bearing installation usually relies on ordinary hoisting. During the leveling process, workers often use crushed stone to fill the bottom of the bearing to level it. This method is inefficient, and the crushed stone used for leveling is prone to deviating from its original position when the epoxy mortar is filled. This can easily lead to the epoxy mortar not being dense between the bearing and the bearing pad.

[0004] Therefore, this utility model provides an auxiliary device for bridge bearing installation to solve the above problems. Utility Model Content

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] This utility model provides an auxiliary device for bridge bearing installation, such as... Figure 1-4 As shown, the bridge bearing installation auxiliary device includes an installation frame 1. Installation seats 2 are fixedly installed at the corners of the installation frame 1. Adjusting screws 3 are threaded into each of the four sets of installation seats 2. Support plates 5 are rotatably installed at the lower ends of each of the four sets of adjusting screws 3. Guide grooves 7 are provided on the inner walls of the front, rear, left, and right ends of the installation frame 1. Two sets of transverse adjusting plates 14 are slidably installed in the two sets of guide grooves 7 on the left and right sides of the installation frame 1. Two sets of longitudinal adjusting plates 15 are slidably installed in the two sets of guide grooves 7 on the front and rear sides of the installation frame 1. Two sets of support blocks 16 are fixedly installed on the upper sides of the transverse adjusting plates 14 and the two sets of longitudinal adjusting plates 15. Adjustment components are provided within the four sets of guide grooves 7.

[0017] By adjusting the positions of the two sets of lateral adjustment plates 14 and the two sets of longitudinal adjustment plates 15, the two sets of lateral adjustment plates 14 and the two sets of longitudinal adjustment plates 15 support the bridge bearing. Then, by rotating the four sets of adjustment screws 3, the four corners of the mounting frame 1 are adjusted, thereby achieving the horizontal installation of the bridge bearing.

[0018] The lower ends of the four sets of adjusting screws 3 are all fitted with protective sleeves 4, and the upper and lower ends of the four sets of protective sleeves 4 are respectively connected to the lower side of the mounting base 2 and the upper side of the four sets of adjusting screws 3.

[0019] The four sets of protective sleeves 4 protect the lower ends of the four sets of adjusting screws 3, preventing the surface threads of the four sets of adjusting screws 3 from being impacted and improving the service life of the four sets of adjusting screws 3.

[0020] Anti-slip pads are provided on the lower surface of all four sets of adjusting screws 3.

[0021] By setting anti-slip pads, the friction between the lower ends of the four sets of adjusting screws 3 and the mounting surface is increased, effectively preventing the device from sliding during adjustment and further improving installation accuracy and stability.

[0022] The adjustment assembly includes two sets of longitudinal adjusting screws 8, which are rotatably installed in two sets of guide grooves 7 at the front and rear ends of the mounting frame 1. Transverse adjusting screws 9 are rotatably installed in two sets of guide grooves 7 at the left and right ends of the mounting frame 1. The left and right ends of two sets of transverse adjusting plates 14 are respectively threaded to the two sets of transverse adjusting screws 9. The front and rear ends of two sets of longitudinal adjusting plates 15 are respectively threaded to the two sets of longitudinal adjusting screws 8. Synchronous pulleys 10 are fixedly installed on the right ends of both sets of longitudinal adjusting screws 8, and synchronous belts 11 are sleeved on the two sets of synchronous pulleys 10. The right ends of the longitudinal adjusting screws 8 in the rear guide groove 7 of the mounting frame 1 and the left ends of the longitudinal adjusting screws 8 in the front guide groove 7 of the mounting frame 1 are both fixedly installed with first bevel gears 12. The front ends and rear ends of the transverse adjusting screws 9 in the left end of the mounting frame 1 are both fixedly installed with second bevel gears 13. The two sets of first bevel gears 12 mesh with each other.

[0023] When installing bridge bearings of different sizes, operators can rotate two sets of longitudinal adjusting screws 8 and two sets of lateral adjusting screws 9. Since these screws are threadedly connected to two sets of lateral adjusting plates 14 and two sets of longitudinal adjusting plates 15 respectively, rotating them causes the plates to slide within the guide grooves 7, thus adjusting their positions to accommodate different bridge bearing sizes. Simultaneously, because the two sets of first bevel gears 12 mesh with the two sets of second bevel gears 13, rotating one set of longitudinal adjusting screws 8 or lateral adjusting screws 9 will also cause the other set to rotate accordingly, ensuring synchronized adjustment of the two sets of lateral adjusting plates 14 and longitudinal adjusting plates 15, improving the convenience and accuracy of the adjustment.

[0024] Four sets of levelness monitoring instruments 6 are fixedly installed on the upper side of the mounting frame 1, and the four sets of levelness monitoring instruments 6 are located on the four sides of the upper side of the mounting frame 1.

[0025] By setting up four sets of levelness monitoring instruments 6, data is provided for adjusting the four sets of adjusting screws 3, ensuring that the reference surface for the support installation is level.

[0026] Scales are provided at the edges of the guide grooves 7 set at the four ends of the mounting frame 1 (front, back, left, and right).

[0027] By using the scales set at the edges of the guide grooves 7 at the four ends of the frame 1, operators can more accurately adjust the positions of the two sets of horizontal adjustment plates 14 and the two sets of vertical adjustment plates 15, thereby further improving the installation accuracy.

[0028] Working principle: In use, the operator first places the bridge bearing on the upper side of the mounting frame 1. By rotating the two sets of longitudinal adjusting screws 8, the two sets of synchronous pulleys 10, and the synchronous belt 11, the two sets of longitudinal adjusting screws 8 rotate, which in turn drives the two sets of transverse adjusting screws 9 to rotate through the two sets of first bevel gears 12 and the two sets of second bevel gears 13. This, in turn, drives the two sets of transverse adjusting plates 14 and the two sets of longitudinal adjusting plates 15 to adjust, so that the four sets of support blocks 16 on the two sets of transverse adjusting plates 14 and the two sets of longitudinal adjusting plates 15 support the bridge bearing, and place the mounting frame 1 and the supported bridge bearing on the upper side. The bracket is placed on top of the pier column, and then the four corners of the mounting frame 1 are adjusted by rotating the four sets of adjusting screws 3. Therefore, rotating the four sets of adjusting screws 3 can drive the mounting frame 1 to make fine adjustments, thereby achieving horizontal installation of the bridge bearing. During the adjustment process, the operator can observe the scales set at the edges of the four sets of levelness monitoring instruments 6 and the four sets of guide slides 7 to ensure that the reference surface for the bearing installation is level, which improves the installation accuracy and efficiency. After the bridge bearing is fixedly installed, the mounting frame 1 can be removed from the bridge bearing by unfolding the two sets of transverse adjusting plates 14 and the two sets of longitudinal adjusting plates 15.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
