Abstract
Description
Technical Field
[0001] This utility model relates to the field of reaction force device technology, specifically to a reusable rotating traction reaction force seat. Background Technology
[0002] In all bridge rotation projects, the traction reaction seat is one of the components that ensures the bridge can rotate. Its main function is to provide support for the continuous jacks. Traditionally, the traction reaction seat is cast as a whole during the construction of the lower abutment.
[0003] Since the reaction seat is cast in one piece, it can be retained after the rotation operation without affecting the subsequent construction of the working surface. However, if the presence of the reaction seat affects the subsequent construction of the working surface, the reaction seat needs to be dismantled. This results in a large workload, a long construction process, and a waste of resources. Therefore, a reusable rotation traction reaction seat is proposed. Utility Model Content

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments, highlighting the above and other technical features and advantages of the present invention. However, the following embodiments are merely preferred embodiments of the present invention and are not exhaustive.
[0025] Example:
[0026] like Figure 1-4 As shown, this utility model provides a reusable rotating traction reaction seat, including a casting base 1 and an I-beam 2. The casting base 1 is set on the outer edge of the rotating platform, and the I-beam 2 is installed on the top of the casting base 1. A reaction seat body 3 for providing reaction force support is set on the upper part of the casting base 1. A limiting steel plate 4 is set between the I-beams 2, and a hydraulic jack 5 is set between the limiting steel plate 4 and the reaction seat body 3.
[0027] The hydraulic jack 5 uses the limiting steel plate 4 as support to push the reaction seat body 3, thus restricting the movement of the reaction seat body 3.
[0028] The casting base 1 is formed by casting. The setting position of the casting base 1 coincides with the rotation traction direction of the rotating base. After the reaction seat body 3 is connected to the casting base 1, the reaction seat body 3 can provide sufficient support surface for the casting base 1 to facilitate the setting of the continuous jack.
[0029] At least four sets of I-beams 2 are provided, and the four sets of I-beams 2 are respectively set at the four corners of the casting base 1. The four corners of the reaction seat body 3 are provided with connection holes that cooperate with the I-beams 2. During assembly, the I-beams 2 are inserted into the connection holes of the reaction seat body 3. With the connection of the I-beams 2, the casting base 1 and the reaction seat body 3 form a whole. The I-beams 2 provide support for the reaction seat body 3, and the reaction force received by the reaction seat body 3 is transmitted to the casting base 1 through the I-beams 2.
[0030] The bottom of the casting base 1 is provided with a base limiting groove 11, and an auxiliary support block 6 is provided inside the base limiting groove 11. The reaction seat body 3 is supported by the auxiliary support block 6. The bottom of the reaction seat body 3 is provided with a reaction seat limiting groove 31 that cooperates with the auxiliary support block 6. The top of the auxiliary support block 6 is nested inside the reaction seat limiting groove 31. With the cooperation of the base limiting groove 11 and the reaction seat limiting groove 31, the auxiliary support block 6, the casting base 1 and the reaction seat body 3 form a common body. The reaction force received by the reaction seat body 3 can be transmitted to the casting base 1 through the auxiliary support block 6.
[0031] The auxiliary support block 6 is provided in several groups, and the specifications of the auxiliary support block 6 are increased sequentially. By setting auxiliary support blocks 6 with different specifications, different specifications of auxiliary support blocks 6 can be selected according to the height requirements of the reaction seat body 3. Thus, without changing the specifications of the reaction seat body 3, the reaction seat body 3 can be adjusted to the required height position, thereby improving the adaptability of the reaction seat body 3 to different rotation requirements.
[0032] The top of the I-beam 2 has a through hole for mounting the limiting steel plate 4. The limiting steel plate 4 is I-shaped, and its four corners are respectively set in the through holes of the four sets of I-beams 2. Under the support of the four sets of I-beams 2, the limiting steel plate 4 can evenly transmit the force it receives to the I-beam 2. The I-beam 2 serves as the support for the limiting steel plate 4, providing stable counter-direction support for the limiting steel plate 4. At the same time, since the I-beam 2 maintains a stressed state under the push of the limiting steel plate 4, the I-beam 2 and the reaction seat body 3 can also maintain a stable support state, avoiding changes in the relative position between the I-beam 2 and the reaction seat body 3.
[0033] The top of the reaction seat body 3 is provided with a hydraulic jack groove 32. Two sets of hydraulic jacks 5 are respectively set on both sides of the hydraulic jack groove 32. The hydraulic jacks 5 are restricted by the hydraulic jack groove 32. After the reaction seat body 3 and the limiting steel plate 4 are installed in place, the hydraulic jacks 5 are extended by continuously pressing them. The extended hydraulic jacks 5 push the reaction seat body 3 with the limiting steel plate 4 as the base. Under the pushing action of the hydraulic jacks 5, the reaction seat body 3 and the I-beam 2 maintain a stable setting state. In this state, the reaction seat body 3 will not experience slight displacement when serving as a support for the continuous jack, thus ensuring the consistency of the two sets of continuous jacks. The hydraulic jack groove 32 has a continuous jack placement point 33 formed in the middle. In use, one end of the continuous jack is set by abutting against the side of the continuous jack placement point 33. The continuous jack placement point has a through hole for the traction cable to pass through, allowing the traction cable to connect with the continuous jack. The reaction seat body 3 provides traction reaction force for the continuous jack.
[0034] The above description is merely a preferred embodiment of the present utility model and is illustrative rather than restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present utility model, all of which will fall within the protection scope of the present utility model.
