Description

Technical Field

[0001] This invention relates to the field of building engineering technology, specifically to a construction device for seismic isolation bearings in building engineering. Background Technology

[0002] Seismic isolation bearings are special structural devices mainly used between the foundation and the superstructure of a building. By extending the natural vibration period of the structure, they reduce the transmission of seismic energy to the upper structure, thereby achieving the effect of seismic reduction and isolation. The core function of seismic isolation bearings is to isolate the direct impact of seismic waves on the building. During installation, the seismic isolation bearing needs to be connected to the top surface of the lower support pier. Then, a steel mesh is connected to the top surface of the seismic isolation bearing and concrete is poured to form the upper support pier. Finally, the main structure of the building is constructed on the upper support pier.

[0003] During the construction of seismic isolation bearings, after the construction of several lower supports arranged in a rectangular array is completed, the corresponding seismic isolation bearings are transported to the lower supports in a stacked manner and placed on the ground. Then, using hoisting equipment, the seismic isolation bearings are installed sequentially on the top surface of each lower support. The existing installation method is to lift a single seismic isolation bearing with a mobile single-beam crane, move it to the top surface of the lower support to be installed (aligning the mounting holes on the seismic isolation bearing with the pre-drilled connection holes on the lower support), lower the seismic isolation bearing onto the top surface of the lower support, and finally fix the two together with bolts.

[0004] The above operation can only install one seismic isolation bearing at a time. During the entire installation process, the mobile single beam crane needs to be moved to the temporary storage location of the seismic isolation bearing and adjusted several times. This is not only cumbersome to operate, but also affects the installation efficiency of the device. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the above-mentioned difficulties and provide a construction device for seismic isolation bearings in building engineering.

[0006] To solve the above-mentioned technical problems, the technical solution provided by the present invention is as follows: a construction device for seismic isolation bearings in building engineering, including a walking frame with an inverted U-shaped structure, a frame body is provided on the top surface of the walking frame, a connecting component for synchronously lifting multiple stacked seismic isolation bearings is provided in the frame body, the connecting component includes a bearing frame that is slidably disposed at both ends of the frame body and moves up and down synchronously, a top seat is slidably disposed on the top surface of the two bearing frames, and four insert rods that extend into the positioning holes at the four corners of the seismic isolation bearings are fixedly disposed on the bottom surface of the top seat, and a positioning component that prevents the two insert rods on the same side from sliding upward is slidably disposed on each bearing frame;

[0007] The positioning assembly includes a movable seat that is slidably mounted on each support frame and abuts against the top wall of the seismic isolation bearing. Each movable seat has a positioning pin that slides relative to or opposite to each other on both sides. The insertion rod has a pin hole for the positioning pin to extend into. The relative or opposite sliding of the two positioning pins is carried out with the sliding of the movable seat connected to them. The support frame is provided with an adjustment assembly for controlling the sliding of the movable seat.

[0008] The top seat is equipped with a linkage component that enables the two adjustment components to move synchronously. When the top seat slides, it simultaneously drives the adjustment components at both ends to move, thereby automatically compensating for the engagement between the insertion rod and the positioning pin after the insertion rod moves.

[0009] As an improvement, the positioning pins are automatically spring-back connected to both ends of the movable seat. A slide rod is provided in the middle of the movable seat and a wedge block is provided on the slide rod. The opposite ends of the two positioning pins are respectively provided with mating surfaces that are adapted to the wedge block. A positioning element is provided between the wedge block and the inner wall of the movable seat.

[0010] The adjustment assembly includes a mounting groove on the support frame and corresponding to the slide rod. An adjustment screw is rotatably mounted on the mounting groove. A threaded seat that slides with the inner wall of the mounting groove is rotatably mounted on the adjustment screw. A rocker arm is hinged to the threaded seat. The other end of the rocker arm is hinged to the slide rod. The linkage assembly drives the two adjustment screws to rotate synchronously.

[0011] As an improvement, the linkage assembly includes a rotating shaft mounted on the support frame and connected to each adjusting screw. The two adjusting screws have opposite helical directions. Each rotating shaft is equipped with a gear. A toothed plate that meshes with each gear is slidably mounted on the top seat. The two gears slide synchronously relative to or opposite to each other. When the two toothed plates slide relative to each other, they drive the corresponding gear and adjusting screw to rotate. Then, the swing arm swings to drive the sliding rods at both ends to slide relative to each other, and at the same time, the moving seats at both ends slide relative to each other to position the insertion rod.

[0012] As an improvement, the top seat is provided with a groove and a bidirectional lead screw is rotatably mounted in the groove. Both ends of the bidirectional lead screw are threaded and fixedly connected to the corresponding toothed plates on the sliding seat.

[0013] As an improvement, the positioning element includes a tapered rod disposed at the four corners of the opposite end faces of the two wedge blocks, a tapered hole for inserting the tapered rod is provided on the movable seat, and magnets that cooperate with each other are provided on the end faces between the wedge blocks and the inner wall of the movable seat.

[0014] As an improvement, the two ends of the traveling frame are respectively provided with adjusting screws II. Each adjusting screw II is provided with a lifting seat that slides with the traveling frame and is fixedly connected to the corresponding support frame. The top surfaces of the two adjusting screws II are respectively provided with bevel gears I. The traveling frame is provided with a reversing shaft and a bevel gear II that meshes with bevel gears I is provided on the reversing shaft. The other end of the reversing shaft is provided with a worm gear I. The traveling frame is provided with a worm gear I that meshes with worm gear I. A half shaft is provided between the two worm gears I. The end of either worm gear I is connected to the end face of the motor I.

[0015] As an improvement, a fixed seat is provided in the middle of the top seat, and an electric cylinder is provided on the support frame, with the movable end of the electric cylinder fixedly connected to the fixed seat.

[0016] The advantages of this invention compared to the prior art are as follows:

[0017] 1. With the help of the traveling frame, connecting components, and positioning components, multiple stacked seismic isolation bearings can be lifted synchronously in a single operation. Then, the entire bearing is moved to the top surface of the lower support pier to be installed, and the bottommost seismic isolation bearing is connected to the lower support pier. After the connection is completed, the traveling frame is controlled to move to the top surface of the next lower support pier to be installed and the bottommost seismic isolation bearing is connected to it. In this way, multiple seismic isolation bearings can be connected to multiple lower supports piers in sequence in a single lift, thereby improving the installation efficiency of this device.

[0018] 2. Under the action of the positioning component, the positioning pin and the pin hole can be engaged through the relative sliding of the two ends, so that the insertion rod is positioned at the top wall of the lowest seismic isolation support, thereby lifting multiple stacked seismic isolation supports.

[0019] 3. Under the action of the linkage component, the moving seats at both ends can be adjusted to slide relative to each other or in opposite directions, thereby improving the ease of operation of this device;

[0020] 4. Under the sliding action of the top seat, it is possible not only to make fine adjustments to the left and right directions when installing the seismic isolation bearing so that the mounting holes on the seismic isolation bearing are aligned with the connecting holes on the lower support, but also to automatically compensate the adjustment components that control the sliding of the moving seat, thereby improving the efficiency of the device.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings.

[0032] Combined with appendix Figure 1 Appendix Figure 2 and attached Figure 3As shown, a construction device for seismic isolation bearings in building engineering includes a U-shaped walking frame 1. The movement of the walking frame 1 is controlled by electric or manual means, which is the prior art. A frame 111 is provided on the top surface of the walking frame 1. A connecting component 2 is provided inside the frame 111 to synchronously lift multiple stacked seismic isolation bearings 7. The connecting component 2 includes a bearing frame 211 that is slidably set at both ends of the frame 111 and rises and falls synchronously. A top seat 212 is slidably provided on the top surface of the two bearing frames 211. Four insert rods 213 that extend into the positioning holes at the four corners of the seismic isolation bearings 7 are fixed on the bottom surface of the top seat 212. A positioning component 3 is slidably provided on each bearing frame 211 to prevent the two insert rods 213 on the same side from sliding upward. Through the positioning component 3, multiple stacked seismic isolation bearings 7 can be lifted during the upward sliding of the bearing frame 211. Under the action of the sliding of the top seat 212, the mounting holes on the bottom surface of the seismic isolation bearings 7 can be aligned and adjusted with the connecting holes on the lower support.

[0033] The positioning component 3 includes a movable seat 311 that is slidably disposed on each support frame 211 and abuts against the top wall of the seismic isolation support 7. Each movable seat 311 has a positioning pin 312 that slides relative to or opposite to each other on both sides. The insertion rod 213 has a pin hole for the positioning pin 312 to extend into. The relative or opposite sliding of the two positioning pins 312 is carried out with the sliding of the movable seat 311 connected to them. The support frame 211 is provided with an adjustment component for controlling the sliding of the movable seat 311.

[0034] The top seat 212 is provided with a linkage component 4 that enables the two adjustment components to move synchronously. When the top seat 212 slides, it simultaneously drives the adjustment components at both ends to move, thereby automatically compensating for the engagement between the insertion rod 213 and the positioning pin 312 after the insertion rod 213 moves.

[0035] Initially, the top seat 212 is at the topmost position. Using the aforementioned structure, the traveling frame 1 is first moved to the stacked multiple seismic isolation supports 7. The bearing frame 211 is then controlled to slide downwards, causing the top seat 212 and the insert rod 213 to slide downwards, so that the bottom surface of the insert rod 213 is below the top wall of the lowest seismic isolation support 7. Then, the linkage component 4 controls the adjustment component's movement, causing the two moving seats 311 to slide relative to each other. This causes the positioning pins 312 at both ends to move in opposite directions and engage with the pin holes, thereby connecting the multiple seismic isolation supports 7 to the insert rod 213. Next, the multiple seismic isolation supports... The base 7 is lifted so that the bottom surface of the lowest seismic isolation bearing 7 is higher than the top surface of the lower support. Then, the moving frame 1 is moved to align the seismic isolation bearing 7 with the lower support. The sliding operation of the top base 212 is then controlled to align and adjust the mounting holes on the bottom surface of the seismic isolation bearing 7 with the connecting holes on the lower support. Next, the lowest seismic isolation bearing 7 is lowered onto the top surface of the lower support and fixed by bolt connection. Finally, the remaining seismic isolation bearings 7 are installed in sequence. In this way, multiple seismic isolation bearings 7 can be connected to multiple lower supports in sequence in a single lifting operation, thereby improving the installation efficiency of this device.

[0036] Combined with appendix Figure 2 Appendix Figure 3 Appendix Figure 4 Appendix Figure 5 and attached Figure 6 As shown, the positioning pins 312 are automatically spring-back connected to both ends of the movable seat 311. A slide rod 313 is passed through the middle of the movable seat 311, and a wedge block 314 is provided on the slide rod 313. A cavity for the wedge block 314 to slide is opened inside the movable seat 311. The opposite ends of the two positioning pins 312 are respectively provided with mating surfaces 315 adapted to the wedge block 314. A positioning element is provided between the wedge block 314 and the inner wall of the movable seat 311. The positioning element includes a tapered rod 611 provided at the four corners of the opposite end faces of the two wedge blocks 314. A tapered hole is opened on the movable seat 311 for the tapered rod 611 to be inserted. Magnets 612 that cooperate with each other are also provided on the end faces between the wedge block 314 and the inner wall of the movable seat 311. When the two magnets 612 are close to each other, they attract each other.

[0037] The adjustment assembly includes a mounting groove 316 on the support frame 211 and corresponding to the slide rod 313. An adjustment screw 317 is rotatably mounted on the mounting groove 316. A threaded seat 318 is rotatably mounted on the adjustment screw 317 and slides against the inner wall of the mounting groove 316. A rocker arm 319 is hinged to the threaded seat 318. The other end of the rocker arm 319 is hinged to the slide rod 313. The linkage assembly 4 drives the two adjustment screws 317 to rotate synchronously. A guide rod 320 is slidably mounted on the support frame 211 and fixedly connected to the movable seat 311.

[0038] The working principle of the positioning component 3 is as follows: In the initial state, the tapered rod 611 is inserted into the tapered hole, and the two magnets 612 are attracted together, fixing the wedge block 314 to the inner wall of the moving seat 311. The control linkage component 4 drives the adjusting screws 317 at both ends to rotate synchronously. Under the action of the thread force, the threaded seats 318 at both ends slide upward. Under the action of the hinged rocker arm 319, the sliding rods 313 at both ends slide relative to each other, and then drive the moving seats 311 at both ends to slide relative to each other. At this time, the moving seat 311 will first... The conical rod 611 abuts against the outer wall of the seismic isolation bearing 7. Then, the relative sliding adjustment of the two sliding rods 313 will separate the conical rod 611 from the conical hole, releasing the positioning of the wedge block 314. At this time, the sliding rod 313 will drive the wedge block 314 connected to it to slide inward. Under the action of the wedge block 314 and the mating surface 315, the positioning pins 312 at both ends will slide in opposite directions and cooperate with the pin holes on the insertion rod 213, thereby positioning the upward sliding of the insertion rod 213 and connecting the multiple seismic isolation bearings 7 to the insertion rod 213.

[0039] Combined with appendix Figure 4 Appendix Figure 5 and attached Figure 7 As shown, the linkage assembly 4 includes a rotating shaft 411 mounted on the support frame 211 and connected to each adjusting screw 317. The two adjusting screws 317 have opposite spiral directions. Each rotating shaft 411 is provided with a gear 412. A toothed plate 413 that meshes with each gear 412 is slidably mounted on the top seat 212. The two gears 412 slide synchronously relative to each other or in opposite directions. When the two toothed plates 413 slide relative to each other, they drive the corresponding gears 412 and adjusting screws 317 to rotate in opposite directions. Under the opposite action of the threads of the two adjusting screws 317, the threaded seats 318 at both ends slide upward. Then, the swing arm 319 drives the sliding rods 313 at both ends to slide relative to each other. At the same time, the moving seats 311 at both ends slide relative to each other to position the insertion rod 213.

[0040] The top seat 212 has a groove 511 and a bidirectional lead screw 512 is rotatably mounted in the groove 511. Both ends of the bidirectional lead screw 512 are threaded and fixedly connected to the sliding seat 513 with corresponding toothed plates 413. A worm gear 514 is provided in the middle of the bidirectional lead screw 512. A worm gear 515 that meshes with the worm gear 514 is rotatably mounted on the groove 511. The end of the worm gear 515 is connected to the output shaft of the motor 516.

[0041] The working principle of the linkage component 4 is as follows: the starting motor 516 drives the worm gear 515 to rotate, which in turn drives the worm wheel 514 and the double-acting screw 512 to rotate, causing the sliding seats 513 at both ends to slide relative to each other. Then, the toothed plates 413 at both ends slide relative to each other, and the gears 412 at both ends rotate in opposite directions. Under the opposite action of the threads of the two adjusting screws 317, the threaded seats 318 at both ends slide synchronously upward. Then, the swing arm 319 drives the sliding rods 313 at both ends to slide relative to each other, and at the same time, the moving seats 311 at both ends slide relative to each other to position the insertion rod 213.

[0042] Combined with appendix Figure 1 Appendix Figure 8 and attached Figure 9 As shown, the two ends of the walking frame 1 are respectively provided with adjusting screws 112. Each adjusting screw 112 is provided with a lifting seat 113 that slides with the walking frame 1. The lifting seat 113 is fixedly connected to the corresponding support frame 211. The support frame 211 is provided with a sliding groove. A slider for sliding the sliding groove is fixed on the inner wall of the frame 111. The top surfaces of the two adjusting screws 112 are respectively provided with bevel gears 114. The walking frame 1 is provided with a reversing shaft 115, and a bevel gear 116 that meshes with the bevel gear 114 is provided on the reversing shaft 115. The other end of the reversing shaft 115 is provided with a worm gear 117. The walking frame 1 is provided with a worm gear 118 that meshes with the worm gear 117. A half shaft 119 is provided between the two worm gears 118. The end of either worm gear 118 is connected to the end face of the motor 120.

[0043] The working principle of the lifting and lowering of the support frame 211 is as follows: Starting the motor 120, under the action of the half-shaft 119, drives the worm gears 118 at both ends to rotate synchronously, which in turn drives the worm wheels 117 at both ends to rotate synchronously. This then drives the reversing shafts 115 at both ends to rotate synchronously, which in turn drives the bevel gears 116 and 114 to rotate, and further drives the adjusting screws 317 at both ends to rotate synchronously. Under the action of the thread force, the lifting seats 113 at both ends slide synchronously, simultaneously driving the support frame 211 at both ends to lift synchronously. The transmission assembly composed of bevel gears 114, 116, 115, worm wheels 117, and worm gears 118 prevents interference between the top seat 212 and the transmission assembly when the top seat 212 moves to its highest position.

[0044] Combined with appendix Figure 8As shown, the top seat 212 is provided with a fixed seat 121 in the middle, and the support frame 211 is provided with an electric cylinder 122. The movable end of the electric cylinder 122 is fixedly connected to the fixed seat 121. The extension and retraction of the electric cylinder 122 are controlled, which drives the top seat 212 to slide left and right on the support frame 211. At the same time, it drives the multiple vibration isolation supports 7 after lifting to slide left and right. Since the vibration isolation supports 7 and the insertion rod 213 slide, if the threaded seat 318 and the swing rod 319 do not move, the cooperation between the positioning pin 312 and the insertion rod 213 will fail. Therefore, a compensation mechanism is required.

[0045] During the left and right sliding of the top seat 212, the toothed plates 413 at both ends will slide synchronously left and right. Then, the gears 412 at both ends will rotate in the same direction, and the adjusting screws 317 at both ends will rotate in the same direction, causing the threaded seats 318 at both ends to slide in opposite directions. This allows the rocker arm 319 to swing when the slide bar 313 slides, and the sliding of the threaded seat 318 and the sliding of the threaded seat 318 caused by the rotation of the adjusting screw 317 will automatically cancel each other out, thereby automatically compensating for the adjustment components of the moving seat 311 and improving the ease of operation of the device.

[0046] In specific implementation of this invention, the traveling frame 1 is first moved to the stacked seismic isolation supports 7. Then, the bearing frames 211 at both ends are controlled to slide downwards, while the top seat 212 and the insert rod 213 slide downwards, so that the insert rod 213 slides to the lower part of the top wall of the lowest seismic isolation support 7. Then, the linkage component 4 drives the sliding rods 313 at both ends to slide relative to each other, and then drives the moving seat 311 to slide relative to each other, so that the positioning pins 312 at both ends of the moving seat 311 slide in opposite directions and cooperate with the pin holes on the insert rod 213. This allows the upward sliding of the insert rod 213 to be positioned, so that the multiple stacked seismic isolation supports 7 are connected to the insert rod 213. Then, the bearing frame 211 is controlled to slide upwards, while the multiple seismic isolation supports 7 slide upwards, so that the bottom surface of the lowest seismic isolation support 7 is above the top surface of the lower support. The traveling frame 1 is controlled to move and the seismic isolation support 7 is moved to the position corresponding to the lower support.

[0047] Next, the top seat 212 is controlled to slide left and right, simultaneously driving the seismic isolation bearing 7 to slide left and right, aligning the positioning hole on the seismic isolation bearing 7 with the connection hole on the lower support. Then, the bearing frame 211 is controlled to slide downward, driving the seismic isolation bearing 7 downward, so that the seismic isolation bearing 7 falls onto the top surface of the lower support. Finally, the seismic isolation bearing 7 is fixedly connected to the lower support by bolts. Then, the positioning of the insertion rod 213 is released, and the bearing frame 211 is controlled to slide upward, causing the insertion rod 213 to slide to the lower part of the top wall of the upper seismic isolation bearing 7. Then, the insertion rod 213 is positioned by the positioning component 3. Next, the movement of the traveling frame 1 is controlled to move the seismic isolation bearing 7 to the top surface of the next lower support to be connected for connection. Finally, the remaining multiple seismic isolation bearings 7 are installed sequentially from bottom to top. In this way, multiple seismic isolation bearings 7 can be connected to multiple lower supports in a single lifting operation, thereby improving the installation efficiency of this device.

[0048] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
