Description

Technical Field

[0001] The invention relates to the field of translation of buildings, heavy equipment and the like, and in particular to a steel slideway double-track continuous pushing and translation device and a construction method. Background Art

[0002] With the development of society and the continuous adjustment of planning, more and more buildings and heavy equipment (hereinafter referred to as "superstructures") need to be moved. In the process of translation, because the hydraulic jack used for pushing has limited stroke, repeated pushing can easily cause fatigue damage to the superstructure; and because the pushing speed is too slow, the foundation treatment requirements are high; in addition, the repeated pushing period is too long and the efficiency is too low.

[0003] Therefore, an uninterrupted, non-stop continuous pushing and translation device and method is needed to promote the continuous translation of the superstructure, avoid repeated loading of the superstructure, reduce the foundation settlement, improve the pushing and translation efficiency, and effectively improve the safety of the translation project. Summary of the invention

[0004] The core idea of ​​the present invention is to install two steel rails with automatic slot function side by side on the steel slideway, and control the hydraulic jacks installed on the two steel rails to push alternately through the software system, so as to control the smooth transition of force conversion and realize continuous pushing and translation of the upper structure.

[0010] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described here are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0011] The present invention is further described below in conjunction with the accompanying drawings. The present invention discloses a steel slideway double-track continuous pushing and translation device, such as Figure 1 As shown, it is characterized in that two steel rails (2) are installed side by side on the steel slideway (1), and each steel rail (2) is provided with a set of automatic slot reaction seat (3) and a hydraulic jack (4). The automatic slot reaction seat (3) can slide forward along the steel rail (2) with the hydraulic jack (4), automatically slot backward and provide reaction force for the hydraulic jack (4). The hydraulic jacks (4) on the two steel rails (2) are controlled by the software system to push alternately, and the smooth transition of the force conversion is controlled to achieve continuous pushing and translation of the upper structure.

[0012] The steel rail (2) is as follows Figure 2 As shown, it is characterized in that it is composed of an upper cover plate (21), a lower cover plate (22), a web plate (23), etc. The upper cover plate (21) is partially suspended on both sides of the web plate (23), and the upper cover plate is evenly distributed with slots (24), and the spacing of the slots (24) matches the stroke of the hydraulic jack. The steel track is fixed to the steel slideway through the lower cover plate (22), and can be removed from the rear of the translation together with the steel slideway and spliced ​​at the front.

[0013] The automatic slot pin reaction seat (3) is as follows: Figure 3 As shown, it is characterized in that it is composed of a seat body (31), a rotating shaft (32), a slot pin (33), etc. The seat body (31) is connected to the hydraulic jack and can move forward and backward along the steel track with the hydraulic jack. Horizontal guide devices (34) are arranged on both sides of the bottom plate of the seat body (31) to prevent the reaction seat from lateral displacement when moving along the steel track. A baffle (35) is arranged below the horizontal guide device (34) to prevent the reaction seat from turning up when providing reaction force for the hydraulic jack; the rotating shaft (32) connects the slot pin (33) with the seat body (31) so that the slot pin (33) can rotate flexibly around the rotating shaft (32); the slot pin (33) can rotate backward from a vertical downward state, but cannot rotate forward from a vertical downward state because the forward rotation will abut against a block arranged on the seat body.

[0014] The working process of the automatic slot pin reaction seat is as follows Figure 4 As shown in the figure, when the reaction seat is dragged forward by the hydraulic jack, the slot pin is lifted up by the upper cover of the steel track and rotates backward (a). When the slot pin encounters the slot of the upper cover of the steel track, it falls into the slot due to gravity and rotates forward to a vertical downward state (b). At this time, the hydraulic jack extends to push the reaction seat backward, and the slot pin is stuck between the rear edge of the slot and the block of the seat body, so that the reaction seat cannot move backward, thereby providing a forward reaction force for the hydraulic jack (c). When the hydraulic jack retracts, it drags the reaction seat forward again, and the reaction seat is automatically slotted repeatedly.

[0015] A steel slideway double-track continuous pushing and translation method of the present invention comprises the following steps:

[0016] Step 1: Install two steel rails (2) side by side on the steel slideway (1), connect the hydraulic jack (4) to the upper structure, install the automatic slot pin reaction seat (3), and connect it to the hydraulic jack (4);

[0017] Step 2: fully retract the two hydraulic jacks (4). If the slot pin (33) of the first reaction seat (3) falls into a certain slot (24) during the process, proceed to the next step. If not, extend the two hydraulic jacks (4) until the slot pin (33) of the first reaction seat (3) falls into a certain slot (24), and the corresponding first hydraulic jack (4) reaches a jacking force state, and start the continuous jacking software system.

[0018] Step 3: The first hydraulic jack (4) pushes the upper structure to extend slowly, and the second hydraulic jack (4) drags the second reaction seat (3) to retract quickly;

[0019] Step 4: When the first hydraulic jack (4) is about to be fully extended, the slot pin (33) of the second reaction seat (3) just falls into the next slot (24);

[0020] Step 5: The second hydraulic jack (4) is extended quickly to eliminate the gap between the second reaction seat (3) and the steel track (2), and catches up with the first hydraulic jack (4) until it reaches a stress state;

[0021] Step 6: The two hydraulic jacks (4) simultaneously push the upper structure and slowly extend it until the first hydraulic jack (4) is fully extended;

[0022] Step 7: The second hydraulic jack (4) continues to push the upper structure to extend slowly, and the first hydraulic jack (4) drags the first reaction seat (3) to retract quickly;

[0023] Step 8: When the second hydraulic jack (4) is about to be fully extended, the slot pin (33) of the first reaction seat (3) just falls into the slot (24);

[0024] Step 9: The first hydraulic jack (4) is extended quickly to eliminate the gap between the first reaction seat (3) and the steel track (2), and catches up with the second hydraulic jack (4) until the force-bearing state is reached;

[0025] Step 10: The two hydraulic jacks (4) simultaneously push the upper structure and slowly extend it until the second hydraulic jack (4) is fully extended;

[0026] Repeat steps 3 to 10 to achieve continuous and uninterrupted translation of the upper structure until the destination is reached.

[0027] According to the process steps of the construction method, the hydraulic jack can realize three movement modes of rapid extension, rapid retraction and slow extension under the control of the software system. The extension distance of the hydraulic jack can be detected in real time by the software system, and the software system can detect when the slot pin falls into the slot.
