[0001] The present invention relates to the technical field of bridge modular telescopic device installation, and in particular to a device with hoisting and posture adjustment functions and a hoisting posture adjustment method. Background Art

[0002] Expansion joints are crucial components of bridge construction, but their service life is only approximately 15 years, requiring multiple replacements throughout the bridge's lifecycle. On-site replacements require multiple hoisting and leveling operations. If the expansion joint's spatial configuration fails to meet design requirements, the joint will become misaligned with the bridge deck, preventing it from freely expanding and contracting, impacting driving speed, comfort, and safety.

[0003] In the existing technology, large-scale lifting equipment is usually used to lift the telescopic device. However, in bridge maintenance and operation, the appearance cost of large-scale lifting equipment is high, and the construction site shifts are seriously idle, which leads to increased costs and poor economic efficiency of using large-scale lifting equipment.

[0044] Example 1

[0045] like Figure 1 and Figure 2 As shown, an embodiment provides a device with lifting and posture adjustment capabilities, which is mainly used for lifting and posture adjustment of the telescopic device 500 during bridge construction, so that the telescopic device 500 is flush with the bridge deck height, thereby improving vehicle driving comfort and safety.

[0046] The device with lifting and posture adjustment includes a moving unit 100, a lifting unit 400 and a leveling unit 300. The moving unit 100 is used to move the device with lifting and posture adjustment in the horizontal direction, thereby adjusting the horizontal position of the telescopic device 500.

[0047] The leveling unit 300 is mounted on the moving unit 100 and is used to adjust the height of the telescopic device 500, thereby adjusting the flatness of the telescopic device 500 and the bridge deck. Specifically, the leveling unit 300 can drive the telescopic device 500 to move slightly in the height direction.

[0048] The hoisting unit 400 is mounted on the mobile unit 100 and is used to hoist the telescopic device 500. The hoisting unit 400 is used to lift the telescopic device 500 off the ground and place the telescopic device 500 in the expansion joint to complete the hoisting of the telescopic device 500.

[0049] The hoisting unit 400 , the leveling unit 300 and the moving unit 100 are all detachably connected, thereby facilitating assembly and disassembly.

[0050] During construction, the hoisting unit 400, leveling unit 300, and mobile unit 100 can be assembled on-site. The telescopic device 500 is connected to the hoisting unit 400. The hoisting unit 400 is activated and lifted off the ground. The mobile unit 100 is moved so that the telescopic device 500 is aligned with the expansion joint, with the centerline of the telescopic device 500 aligned with the centerline of the expansion joint. The hoisting unit 400 is then activated to place the telescopic device 500 in the expansion joint.

[0051] The height difference between the telescopic device 500 and the bridge deck is measured, and the telescopic device 500 is connected to the leveling unit 300; the leveling unit 300 adjusts the height of the telescopic device 500 according to the measured height difference until the height difference between the telescopic device 500 and the bridge deck meets the flatness requirement, thereby ensuring driving safety.

[0052] Example 2

[0053] like Figures 1 to 3 As shown, in the embodiment, the mobile unit 100 includes a support frame and a counterweight 105; the support frame includes at least one support unit.

[0054] In this embodiment, the support frame includes a support unit. The support unit is a frame consisting of four uprights 101 and eight crossbars 102. A pair of support rods 103 are intersectingly disposed on each side wall of the support unit. The intersecting pair of support rods 103 are hingedly connected at their intersections. The provision of the support rods 103 serves to increase the load-bearing strength of the support unit.

[0055] The uprights 101 may be made of square steel to improve the support strength of the support unit. The crossbars 102 may be made of angle steel; and the support bars 103 may be made of round steel pipes.

[0056] In other embodiments, the upright posts 101 may be made of solid cylindrical or polygonal steel to ensure the load-bearing strength of the support unit. The crossbars 102 may be made of plate-shaped steel. The support rods 103 may be made of solid or tubular square rods, polygonal rods, or other structures.

[0057] The counterweight 105 is placed in the frame of the support unit to increase the weight of the mobile unit 100 itself and prevent the support frame from overturning.

[0058] In other embodiments, the support frame may include two, three, four, or other numbers of support units. Construction personnel can determine the height of the support frame based on construction site requirements, thereby determining the number of support units. Multiple support units are stacked from bottom to top, and secured together using bolts, clamps, or other methods. The counterweight 105 is located within the bottommost support unit to prevent the support frame from tipping over.

[0059] In this embodiment, a roller 104 is installed on the side of the support frame closest to the ground. This roller 104 is used to drive the mobile unit 100 in horizontal movement, thereby facilitating the movement of the equipment capable of lifting and posture adjustment, and facilitating deployment on the construction site. In this embodiment, the roller 104 is an industrial universal wheel, one of which is installed at each of the four corners of the support frame near the bottom. These industrial universal wheels enable the mobile unit 100 to move in any direction on the horizontal plane.

[0060] In some other embodiments, the rolling element 104 may also be an omnidirectional wheel to enable the mobile unit 100 to move in multiple directions on a horizontal plane.

[0061] like Figures 3 to 8 As shown, in the embodiment, a beam 200 is provided on the side of the mobile unit 100 away from the ground. The leveling unit 300 and the hoisting unit 400 are mounted on the mobile unit 100 via the beam 200. One end of the beam 200 is fixedly connected to the mobile unit 100, and the other end of the beam 200 protrudes from the mobile unit 100. The leveling unit 300 and the hoisting unit 400 are mounted on the end of the beam 200 that protrudes from the mobile unit 100.

[0062] Specifically, the beam frame 200 includes a main beam 201 and a distribution beam 202. A pair of main beams 201 are symmetrically positioned on the side of the mobile unit 100 away from the ground. One end of each main beam 201 is fixedly connected to the mobile unit 100; the other end of each main beam 201 protrudes from the mobile unit 100. The distribution beam 202 spans between the two main beams 201 and is positioned at the end of the main beam 201 that protrudes from the mobile unit 100. The leveling unit 300 and the hoisting unit 400 are mounted on the distribution beam 202.

[0063] In this embodiment, the main beam 201 is formed by splicing two I-beams. Specifically, the upper flange seams and lower flange seams of the two I-beams are welded to connect them, so that the two I-beams are firmly connected.

[0064] In other embodiments, the main beam 201 can be directly made of square steel or other structures to achieve the supporting function.

[0065] A connecting piece 201 a for connecting to the column 101 is provided on one side of the main beam 201 close to the mobile unit 100 .

[0066] In this embodiment, the connecting member 201a is in the shape of a square tube. One end of the connecting member 201a is fixedly connected to the main beam 201; the other end of the connecting member 201a is sleeved on the column 101. The center line of the connecting member 201a is arranged corresponding to the weld seam of the main beam 201. Corresponding pin holes are provided on the connecting member 201a and the column 101. The connecting member 201a is fixedly connected to the column 101 by inserting a pin shaft, thereby achieving a fixed connection between the main beam 201 and the column 101. The pin hole is arranged perpendicular to the length direction of the main beam 201; a reinforcing plate (not shown in the figure) is provided on one side of the connecting member 201a along the length direction of the main beam 201 to improve the connection strength of the connecting member 201a.

[0067] In some other embodiments, the connecting member 201 a is specifically configured according to the shape of the column 101 so that the connecting member 201 a can be smoothly sleeved on the column 101 .

[0068] In this embodiment, the distribution beam 202 is formed by splicing two I-beams. Specifically, the upper flanges of the two I-beams are welded together; a gap of 3-5 mm is left between the lower flanges of the two I-beams, and the ends of the lower flanges of the two I-beams are welded together using steel bars, thereby forming a through groove with sealed ends between the lower flanges of the two I-beams.

[0069] In some other embodiments, the distribution beam 202 may also be made of tubular steel, with a through groove provided at the bottom of the tubular steel.

[0070] The distribution beam 202 is installed between the two main beams 201 through a limiting member 203. One limiting member 203 is fixed to each of the two main beams 201, and the two limiting members 203 are arranged opposite to each other. The limiting member 203 includes a limiting frame 203a and a limiting plate 203b; the limiting frame 203a is in the shape of a door frame, and the open end of the limiting frame 203a is connected to the main beam 201. The two ends of the distribution beam 202 are respectively inserted into the limiting frames 203a at the corresponding ends, and the limiting frames 203a limit the upward and downward movement of the distribution beam 202 relative to the main beam 201. The limiting plate 203b is fixed to the end of the limiting frame 203a away from the distribution beam 202, thereby blocking the distribution beam 202 between the two limiting members 203, and the limiting plate 203b limits the movement of the distribution beam 202 along the length direction. Thereby, the distribution beam 202 is fixedly connected to the main beam 201 .

[0071] In some other embodiments, the distribution beam 202 may also be fixedly connected to the main beam 201 by bolt connection, welding, or the like.

[0072] like Figure 9 As shown in the embodiment, the leveling unit 300 includes a hydraulic leveling device 301, which is fixedly mounted on the distribution beam 202 via a bracket 303. The bracket 303 is in the form of a door frame, and the open end of the bracket 303 is fixedly connected to the distribution beam 202 via bolts. The hydraulic leveling device 301 is disposed at the end of the bracket 303 away from the distribution beam 202.

[0073] The leveling unit 300 also includes a connecting rod 304, one end of which is connected to the hydraulic leveling device 301; the other end of the connecting rod 304 is connected to the telescopic device 500. During use, the hydraulic leveling device 301 drives the connecting rod 304 to move up and down, thereby driving the telescopic device 500 to move up and down, thereby adjusting the height of the telescopic device 500.

[0074] In this embodiment, the hydraulic leveling device 301 utilizes a tensioning jack, and the connecting rod 304 utilizes finely rolled threaded steel bars. A tool anchor 302 is provided at the connection between the connecting rod 304 and the hydraulic leveling device 301. This anchor is used to anchor the connecting rod 304. When the hydraulic leveling device 301 tensions the connecting rod 304 to a certain position, the tool anchor 302 secures the connecting rod 304. This prevents the connecting rod 304 from moving up and down due to hydraulic instability that may occur within the hydraulic leveling device 301. This ensures that the hydraulic leveling device 301 does not fluctuate after adjusting the telescopic device 500 to a certain height.

[0075] A nut is provided on the side of the distribution beam 202 near the bracket 303, and the connecting rod 304 is threadedly connected to the nut, further improving the stability of the connecting rod 304. The end of the connecting rod 304, away from the hydraulic leveling device 301, passes through the through slot between the lower wings of the distribution beam 202; the connecting rod 304 is suspended below the distribution beam 202 to facilitate its connection to the telescopic device 500.

[0076] The end of the connecting rod 304 away from the hydraulic leveling device 301 is connected to a pad 305. In use, the telescopic device 500 is clamped between the pads 305, and the pads 305 and the telescopic device 500 are locked by nuts to achieve a fastening connection between the connecting rod 304 and the telescopic device 500.

[0077] In some other embodiments, the leveling unit 300 may also use a lifting component such as a lifting motor to drive the telescopic device 500 to move up and down to achieve height adjustment.

[0078] like Figure 10 As shown, in the embodiment, the hoisting unit 400 includes a movable member 401 and a sling 402. The movable member 401 is connected to the distribution beam 202 and can move along the distribution beam 202. The sling 402 is hoisted below the movable member 401, thereby driving the sling 402 to move along the distribution beam 202. The output end of the sling 402 is connected to the telescopic device 500, and the sling 402 is used to lift and lower the telescopic device 500.

[0079] In this embodiment, the movable member 401 is an I-beam pulley, which spans the lower wings of the distribution beam 202. The I-beam pulley can roll along the lower wings of the distribution beam 202, thereby driving the hoist 402 to move relative to the distribution beam 202. During use, construction personnel can adjust the position of the hoisting unit 400 relative to the distribution beam 202 as needed.

[0080] In some other embodiments, the movable member 401 may also be an H-steel roller.

[0081] In some other embodiments, the movable member 401 may also be a slider, which is limited in the distribution beam 202 and can slide along the distribution beam 202 to enable the lifting unit 400 to move relative to the distribution beam 202.

[0082] In this embodiment, the lifting device 402 is an electric hoist, and the telescopic device is lifted by the electric hoist.

[0083] In some other embodiments, the sling 402 may also be a sling composed of a lifting motor and a reel or other types of lifting slings to achieve lifting operations.

[0084] In some other embodiments, the hoisting unit 400 may also be a non-mobile electric hoist, and the hoisting unit 400 is directly fixedly connected to the distribution beam 202 .

[0085] In this embodiment, the various components of the lifting and posture adjustment device are removable, allowing for rapid assembly at the construction site during construction. Furthermore, the device can be adjusted to suit the construction site environment to meet construction requirements; for example, the height of the mobile unit 100 can be adjusted to meet the height requirements of different construction sites. Therefore, the lifting and posture adjustment device of this application can meet the needs of various construction environments without requiring large-scale lifting equipment, thereby reducing construction costs.

[0086] like Figure 10 and Figure 11 As shown, during the construction process, two devices with lifting and posture adjustment functions are activated; the connecting rod 304 is removed from the leveling unit 300, and the connecting rod 304 is connected to the hook of the sling 402 via the sling 403; the two ends of the telescopic device 500 are respectively connected to one of the connecting rods 304, and locked with the pad 305 and the nut. The sling 402 is started to lift the telescopic device 500 off the ground. The moving unit 100 is moved, thereby driving the telescopic device 500 to move, so that the telescopic device 500 moves to the top of the expansion joint, that is, the center line of the telescopic device 500 corresponds to the center line of the expansion joint. The sling 402 is started to place the telescopic device 500 in the expansion joint, completing the lifting of the telescopic device 500 and the horizontal position adjustment.

[0087] Activate the four devices capable of lifting and adjusting the posture. Connect one end of the connecting rod 304 to the hydraulic leveling device 301, and the other end of the connecting rod 304 to a corner of the telescopic device 500. Each of the four corners of the telescopic device 500 is connected to a corresponding connecting rod 304, and the connecting rods 304 are locked together using spacers 305 and nuts. Measure the height difference between the telescopic device 500 and the bridge deck. Based on this height difference, synchronized hydraulic control is used to synchronously adjust the height of the four corners of the telescopic device 500 to achieve flatness adjustment. This synchronized hydraulic control can be achieved using synchronous motors, which synchronously drive the hydraulic leveling devices 301 of the four devices capable of lifting and adjusting the posture. The height difference between the telescopic device 500 and the bridge deck is then remeasured. If it does not meet the requirements, the above adjustments are repeated until the required height difference is met. The telescopic device 500 is then fixed, and the leveling work of the telescopic device 500 is completed.

[0088] Example 3

[0089] like Figure 12 As shown in the embodiment, a method for adjusting the lifting posture using the device capable of lifting and posture adjustment includes:

[0090] S100: Move the expansion device 500 to directly above the expansion joint, and place the expansion device 500 in the expansion joint.

[0091] Specifically, the telescopic device 500 is lifted by the hoisting unit 400 of the equipment with hoisting and posture adjustment; and the horizontal position of the telescopic device 500 is adjusted by moving the moving unit 100 of the equipment with hoisting and posture adjustment, so that the telescopic device 500 is located directly above the expansion joint, that is, the center line of the telescopic device 500 corresponds to the center line of the expansion joint; and the telescopic device 500 is placed in the expansion joint.

[0092] S200: Measure the height differences between the four corners of the telescopic device 500 and the bridge deck respectively, and set the adjustment parameters of the hydraulic leveling device 301 according to the height differences, so that the hydraulic leveling device 301 drives the four corners of the telescopic device 500 to move up and down.

[0093] Specifically, the four corners of the telescopic device 500 are connected to a leveling unit 300 equipped with a lifting and posture adjustment device, and the four corners of the telescopic device 500 are fixedly connected to the connecting rod 304. The height difference between the four corners of the telescopic device 500 and the bridge deck is measured, and the height difference is input through synchronous hydraulic control to synchronously adjust the height of the four corners of the telescopic device 500.

[0094] S300: Re-measure the height difference between the four corners of the telescopic device 500 and the bridge deck. If it still does not meet the requirements, repeat step S200 until the height difference between the four corners of the telescopic device 500 and the bridge deck meets the requirements, thereby completing the leveling operation of the telescopic device.
