Description

Technical Field

[0001] The invention relates to the technical field of highway bridge construction, and more specifically to a highway bridge construction hanging basket. Background Art

[0002] During the construction of a highway bridge, due to the high position of the bridge, in order to increase the construction safety of the workers, a hanging basket and a lifting mechanism are used. The hanging basket is connected to the top of the bridge through a steel rope. The lifting mechanism and the steel rope are controlled to cooperate according to the position required for processing, and the hanging basket is controlled to be in a suitable position for processing. The prior art document CN112049016A provides a highway bridge construction hanging basket, which includes a frame, a pedal, and a lifting mechanism. The pedal is fixed to the bottom of the frame, and the lifting mechanism is installed on both sides of the frame. The burrs on the outer wall of the steel rope are removed by a cleaning block to reduce the friction between the steel rope and the slide rail, which is conducive to the same height of the two sides of the hanging basket and reduces the tilt of the hanging basket.

[0003] Although the above patent can remove burrs on the outer wall of the steel rope by removing blocks and reduce the tilting phenomenon of the hanging basket, the hanging basket is suspended by steel ropes for moving work, and it is still easy to shake during use, causing the hanging basket to move. Secondly, the deviation of the load-bearing center of gravity in the hanging basket makes the force on both sides of the hanging basket uneven, which will also cause the hanging basket to tilt and shake. In the case of severe deviation of the center of gravity, it may even overturn the hanging basket, making it very easy for operators to be in danger on the hanging basket. In addition, the shaking of the hanging basket will also cause wear of the steel rope and reduce its service life.

[0004] In the existing solution CN214656350U, a moving wheel in contact with one side of the viaduct is provided on one side of the hanging basket to prevent the hanging basket from shaking during operation. However, this structure is only suitable for use when constructing one side of the bridge. The above problems still exist when constructing the bottom of the bridge, and the contact distance between the moving wheel and the bridge is limited by the length of the spring rod, making the support adjustment distance relatively short. The above problems also exist in CN216809632U. Although the support distance can be adjusted by turning the adjustment screw in CN217172916U, the operator needs to squat and change position to operate one by one, which is likely to cause the center of gravity of the hanging basket to change again, causing the hanging basket to shake and tilt again. In view of this, we propose a highway bridge construction hanging basket. Summary of the invention

[0045] Please refer to the attached Figure 7 The transmission part 600 includes a first transmission shaft 601 rotatably connected to both sides of the inside of the base 100 through a bearing, and worms 602 are installed on both sides of the outside of the first transmission shaft 601, and the outside of the worm 602 is meshed with a worm wheel 603, and the worm wheel 603 is installed on the outside of each group of first threaded sleeves 507a. The two groups of first transmission shafts 601 are connected through a first pulley transmission assembly 604. A first bevel gear 605 is installed on the outside of each group of second threaded sleeves 507b, and the outside of the first bevel gear 605 is meshed with a second bevel gear 606. The inside of the base 100 is rotatably connected to a second transmission shaft 607 through a bearing, and the second transmission shaft 607 is fixedly connected to the second bevel gear 606. The first transmission shaft 601 and the second transmission shaft 607 are matched and connected through a driving part 700.

[0046] The first pulley transmission assembly 604 is composed of a first wheel and a first belt. The first wheel is installed outside the two first transmission shafts 601, and the first belt is sleeved on the outside of the two first wheels. When one set of first wheels rotates, the first belt drives another set of first wheels to rotate, so that the two first transmission shafts 601 are connected by transmission.

[0047] In the above technical solution, when the first transmission shaft 601 rotates, it drives the worm 602 to rotate. Under the action of the meshing connection between the worm 602 and the worm wheel 603, the first threaded sleeve 507a rotates, so that under the action of the threaded connection, the first threaded rod 508a drives the first base 501a to move upward, so as to adapt to the upper and lower spacing between different bridges and the hanging basket as a whole 200, facilitate support and fixation, and avoid shaking. Secondly, the second transmission shaft 607 rotates to drive the second bevel gear 606 to rotate. The meshing connection between the first bevel gear 605 and the second bevel gear 606 makes the second threaded sleeve 507b rotate. Under the action of the threaded connection, the second threaded rod 508b drives the second base 501b to move, squeezes the side bridge surface, thereby avoiding shaking of the hanging basket as a whole 200 during operation and increasing stability.

[0048] Please refer to the attached Figure 8The driving unit 700 includes a movable plate 701 disposed on one side of the base 100, and an electric telescopic rod 702 is disposed outside the movable plate 701, one end of the electric telescopic rod 702 is mounted on the outer wall of the base 100, and the other end is connected to the movable plate 701, and a motor 703 is also mounted on the outside of the movable plate 701, and a driving gear 704 is mounted on the output shaft of the motor 703, and a first driven gear 705 is meshed and connected to one side of the outside of the driving gear 704, and a first rotating shaft 706 is mounted inside the first driven gear 705, and the first rotating shaft 706 is mounted inside the first driven gear 705. One end of the shaft 706 is rotatably connected to the inside of the base 100 through a bearing, the first transmission shaft 601 and the first rotating shaft 706 are connected to each other through a second pulley transmission assembly 707, the other side of the outside of the driving gear 704 is meshed with a second driven gear 708, and a second rotating shaft 709 is installed inside the second driven gear 708, one end of the second rotating shaft 709 is rotatably connected to the inside of the base 100 through a bearing, and the second transmission shaft 607 and the second rotating shaft 709 are connected to each other through a third pulley transmission assembly 710;

[0049] The second pulley transmission assembly 707 is composed of a second wheel and a second belt. The second wheel is installed outside the first transmission shaft 601 and the first rotating shaft 706, and the second belt is sleeved on the outside of the two second wheels. When one set of second wheels rotates, the second belt drives another set of second wheels to rotate, so that the first rotating shaft 706 and the first transmission shaft 601 are connected in transmission.

[0050] The third pulley transmission assembly 710 is composed of a third wheel and a third belt. The third wheel is installed outside the second transmission shaft 607 and the second rotating shaft 709, and the third belt is sleeved on the outside of the two third wheels. When one set of third wheels rotates, the third belt drives another set of third wheels to rotate, so that the second transmission shaft 607 and the second rotating shaft 709 are connected by transmission.

[0051] In the above technical solution, the movable plate 701 is driven to move back and forth by the electric telescopic rod 702, so that the connection relationship between the driving gear 704 and the first driven gear 705 and the second driven gear 708 is in three states, one is the default state, the driving gear 704, the first driven gear 705 and the second driven gear 708 are meshed, one is that the electric telescopic rod 702 drives the movable plate 701 to extend, the driving gear 704 and the first driven gear 705 are meshed, and the driving gear 704 and the second driven gear 708 are disengaged, and the other is that the electric telescopic rod 702 drives the movable plate 701 to retract Movement, the driving gear 704 and the first driven gear 705 are disengaged, and the driving gear 704 is meshed with the second driven gear 708. In summary, when the first support part 500a and the second support part 500b are controlled, three types of movement can be achieved. One is that the first support part 500a moves alone, one is that the second support part 500b moves alone, and the other is that the first support part 500a and the second support part 500b move synchronously, which is convenient for separate independent support of the top side, and can also be used for synchronous support, which greatly increases the scope of application. Among them, the synchronous support is particularly suitable for construction and maintenance at the pier position.

[0052] It is worth noting that the first driven gear 705 and the second driven gear 708 are not located on the same spatial layer, and the first driven gear 705 and the second driven gear 708 are staggered, and the thickness of the driving gear 704 is at least three times that of the first driven gear 705 and the second driven gear 708;

[0053] In the above technical solution, the thickness of the driving gear 704 is greater than the thickness of the first driven gear 705 and the second driven gear 708, so that the driving gear 704 can mesh with the first driven gear 705 and the second driven gear 708 at the same time and can perform separate meshing movements.

[0054] Embodiment 2

[0055] In order to further reduce the possibility of the hanging basket shaking and improve the safety of the operator's high-altitude operation, the present embodiment is different from the above-mentioned embodiment 1 in that:

[0056] A plurality of pressure sensing modules are arranged inside the bottom plate of the hanging basket 200, a cavity is opened inside the bottom plate of the hanging basket 200, a counterweight block is slidably arranged inside the cavity, a magnet is arranged inside the counterweight block, and an electromagnet is arranged on at least two side walls inside the bottom plate of the hanging basket 200, and the on-off operation of the electromagnet is triggered in response to the pressure difference of the pressure signals of the plurality of pressure sensing modules;

[0057] In the above technical solution, pressure sensing modules are arranged on both sides or around the bottom plate of the hanging basket 200. When the operator enters the hanging basket, the pressure sensing module in the bottom plate of the hanging basket 200 detects the pressure signal, and the pressure difference threshold value and the upper limit value of the pressure difference when the electromagnet is energized are set through the control panel 400. Taking the pressure sensing modules arranged on both sides as an example, when the operator's standing position in the hanging basket is offset, the force distribution on both sides of the bottom plate is different, so that the output signals of the pressure sensing modules on both sides are different. If the output signal difference of the pressure sensing modules on both sides can be divided into three cases:

[0058] One is that the pressure difference is less than the set magnet energization pressure difference threshold, which means that the operator is standing in the basket properly, so that the force on the bottom plate is relatively uniform. At this time, no additional control operation is required;

[0059] One is that the pressure difference is between the pressure difference threshold value and the upper limit value of the pressure difference when the electromagnet is energized, indicating that the operator's standing position in the hanging basket is skewed, and the hanging basket may tilt and shake when it rises. At this time, the electromagnet on the side with a smaller pressure value is energized to attract the magnet in the counterweight block, and the counterweight block slides to the side with less force on the bottom plate through the magnetic force. The sliding distance is positively correlated with the pressure difference, so that the overall force distribution of the hanging basket is relatively uniform, so as to avoid the hanging basket from tilting and shaking;

[0060] The remaining one is that the pressure difference is greater than the upper limit of the pressure difference, which means that the operator's position in the hanging basket is obviously seriously offset and has exceeded the adjustment range of the counterweight block. At this time, the operator's position needs to be adjusted to change the size of the pressure difference on both sides of the bottom plate. Before the operator's position is adjusted to a suitable one, the driving components that control the rising of the hanging basket are forced to be suspended to avoid large tilts, hanging basket rotation, etc. during the hanging basket rising project.

[0061] It should be noted that the above control is applicable to the autonomous adjustment in the preparation stage for the hanging basket to rise and during the process of the hanging basket to rise.

[0062] Furthermore, multiple counterweight blocks can be provided, wherein an electromagnet is provided inside the counterweight block located in the middle, and magnets are provided inside the counterweight blocks located at the periphery, and a plurality of slide grooves are provided on the inner wall of the cavity, and the counterweight blocks located at the periphery slide in the corresponding slide grooves, and the degree of convergence and dispersion of the peripheral counterweight blocks in the cavity is changed by triggering the on and off of the electromagnet in the middle counterweight block;

[0063] Among them, multiple push blocks are arranged on the outside of the middle counterweight block, an oblique push block is slidably arranged in the outer counterweight block, a sliding block that slides with the slide groove is arranged at the bottom of the oblique push block, and an elastic part is connected and fixed between the oblique push block and the inside of the outer counterweight block.

[0064] In the above technical solution, there is one central counterweight block, and the number of peripheral counterweight blocks can be 2, 4, 8, etc. When there are 2 peripheral counterweight blocks, the 2 peripheral counterweight blocks are located at the opposite sides of the central counterweight block, and when there are 4 peripheral counterweight blocks, the 4 peripheral counterweight blocks are located at the surrounding sides of the central counterweight block; when there are 8 peripheral counterweight blocks, they form a nine-square grid structure together with the entire counterweight block. Correspondingly, slide grooves are provided on the medians of the opposite sides of the bottom plate cavity, the medians of the surrounding areas, the medians of the surrounding areas, and the diagonals, and the central counterweight block is located at the center intersection.

[0065] The on and off of the electromagnet in the middle counterweight block responds to the first situation mentioned above. When the operator is in an appropriate position, such as standing between the hanging baskets, the electromagnet in the middle counterweight block is energized to have a magnetic force that repels the magnets in the outer counterweight blocks, or the electromagnet is not energized, so that the outer counterweight blocks are evenly dispersed in the bottom plate, making the force distribution of the bottom plate more uniform, while reducing the force in the middle of the bottom plate. After the operator's position changes, the pressure difference may change, so that the pressure difference is between the pressure difference threshold value when the electromagnet is energized and the upper limit value of the pressure difference. Then, multiple counterweights need to slide and adjust their positions at the same time. At this time, the electromagnet in the middle counterweight is energized to have magnetism that attracts the magnets in the outer counterweights, so that the outer counterweights gather toward the middle counterweight. The push block on the middle counterweight pushes the oblique push block in the outer counterweight to drive the slider to slide and be stored inside the counterweight, so that only the slider at the bottom of the middle counterweight is still in the slide slot. Then, the electromagnet on the side with a smaller pressure value is energized to have magnetism that attracts the magnet in the counterweight, and the counterweight slides toward the side of the bottom plate with less force through the magnetic force. Among them, the electromagnet in the middle counterweight can be de-energized after multiple counterweights are closed together to avoid mutual influence of the magnetic forces between the two electromagnets. The operator controls the control panel 400 to drive the first support part 500a and the second support part 500b to perform the support work;

[0066] When supporting the bottom surface of the bridge, the electric telescopic rod 702 is driven to extend by controlling the control panel 400, the driving gear 704 and the first driven gear 705 are meshed and connected, and the driving gear 704 and the second driven gear 708 are disengaged. At this time, under the action of the meshing connection between the driving gear 704 and the first driven gear 705, the first rotating shaft 706 drives the first transmission shaft 601 to rotate and move through the second pulley transmission assembly 707. Under the action of the transmission connection of the first pulley transmission assembly 604, the two groups of first transmission shafts 601 move synchronously, and the first threaded sleeve 507a and the first threaded rod 508a are threadedly connected through the meshing connection of the worm 602 and the worm wheel 603, so that the first base 501a is moved, so that the first support block 503a contacts the bottom surface of the bridge, and the hanging basket as a whole 200 is supported;

[0067] When supporting the side surface of the bridge, the control panel 400 is used to drive the electric telescopic rod 702 to retract, the driving gear 704 and the first driven gear 705 are released from meshing connection, and the driving gear 704 is meshed and connected with the second driven gear 708. At this time, under the action of the meshing connection between the driving gear 704 and the second driven gear 708, the second rotating shaft 709 drives the second transmission shaft 607 to rotate through the third pulley transmission assembly 710, and under the action of the meshing connection between the first bevel gear 605 and the second bevel gear 606, the second threaded sleeve 507b is rotated, and under the action of the threaded connection, the second threaded rod 508b drives the second base 501b to move, so that the second support block 503b contacts the side of the bridge, and the hanging basket as a whole 200 is supported;

[0068] When the bottom and side surfaces of the bridge are supported synchronously, the electric telescopic rod 702 is driven to enter the default state by controlling the control panel 400, and the driving gear 704, the first driven gear 705 and the second driven gear 708 are meshed and connected, and driven by the motor 703, so that the first transmission shaft 601 and the second transmission shaft 607 rotate synchronously, so that the first base 501a and the second base 501b move synchronously, so that the first support block 503a and the second support block 503b support the bottom and side surfaces of the bridge;

[0069] When the first support part 500a and the second support part 500b are working, when the first support block 503a or the second support block 503b contacts the bridge, the elastic deformation generated by the internal first spring 505a or the second spring 505b applies pressure to the contact surface of the bridge. When the bridge surface has concave and convex surfaces, it can fit more closely with the concave and convex surfaces of the bridge and clamp it, thereby providing stable support for the hanging basket as a whole 200.
