Technical Field

[0001] This invention relates to the field of synchronous sliding device technology, and more specifically, to a hydraulically assisted push-type hanging basket synchronous sliding device and method. Background Technology

[0002] Hanging baskets are an indispensable key piece of equipment in the construction of modern long-span bridges. During the bridge construction process, especially for the repair of the outer surface of high piers, long-span structures and bridge deck ancillary facilities (such as side railings) after demolding, as well as tie rod cutting and tie rod hole grouting, hanging baskets need to be moved frequently between different construction sections of the bridge deck to meet the requirements of continuous operation.

[0003] In the prior art, such as the walking structure and bridge hanging basket disclosed in patent CN221919031U, a hydraulic device and a pneumatic device are used to drive the hanging basket to move. However, the hanging basket itself is a heavy combined structure of concrete pouring and steel structure assembly. Relying solely on hydraulic and pneumatic devices for driving often leads to high walking resistance and difficulty in moving. At the same time, the hydraulic and pneumatic components are subjected to extremely high loads for a long time, which can easily cause equipment damage. Summary of the Invention

[0004] This invention provides a hydraulically assisted push-type hanging basket synchronous sliding device and method, which solves the technical problems in related technologies where relying solely on hydraulic and pneumatic devices for driving often leads to high walking resistance and difficulty in movement, while hydraulic and pneumatic components are subjected to extremely high loads for a long time, which can easily cause equipment damage.

[0005] This invention provides a hydraulically assisted push-type hanging basket synchronous sliding device, comprising: Track pad beam, which is provided with a track extending in the direction of travel; The support base is slidably installed within the track; The main crossbeam is fixedly connected to the top of the support base and is used to support the hanging basket equipment and the counterweight beam; The traveling mechanism, located at the rear of the support base, is used to apply forward main power to the support base; An auxiliary thrust mechanism, located inside the track pad beam, is used to lift the support seat upward and apply a forward auxiliary thrust to it; The anti-deviation mechanism is located between the main crossbeam and the track pad beam to guide and limit the lateral deviation of the main crossbeam during travel.

[0006] As a further optimization of the present invention, the walking mechanism includes a hydraulic cylinder, the output end of which is detachably connected to the tail of the support base.

[0007] As a further optimization of the present invention, the auxiliary thrust mechanism includes: Hydraulic jacks are fixedly installed inside the track pad beams; The sliding device, located at the output end of the hydraulic jack, has a steel roller that can rotate actively. The steel roller is used to contact the bottom of the support base and generate forward friction.

[0008] As a further optimization of the present invention, the gliding device includes a motor and a plurality of steel rollers driven to rotate by the motor, the axis of the steel rollers being perpendicular to the direction of travel.

[0009] As a further optimization of the present invention, a buffer mechanism is provided between the output end of the hydraulic jack and the sliding device, the buffer mechanism including an elastic element and / or a damping element.

[0010] As a further optimization of the present invention, the anti-deviation mechanism includes: The guide groove is opened on the side of the track pad beam along the direction of travel; The guide block slides within the guide groove; The electric push rod is hinged at one end to the side of the main crossbeam and at the other end to the guide block.

[0011] As a further optimization of the present invention, the guide block is provided with a locking element, which is used to lock the guide block in a certain position of the guide groove after the walking is completed.

[0012] As a further optimization of the present invention, the hanging basket device includes a lower crossbeam and a steel rope connecting the lower crossbeam and the anchor beam. The steel rope and the lower crossbeam are connected by a detachable fastening mechanism.

[0013] As a further optimization of the present invention, the bottom of the counterweight beam is provided with counterweight blocks that can be added or removed.

[0014] A method for synchronous sliding of a hydraulically assisted push-type hanging basket, employing the aforementioned hydraulically assisted push-type hanging basket synchronous sliding device, includes the following steps: Step 1: Fix the track pad beam to the cast-in-place beam base, slide the support base and main crossbeam onto the track, and set up the hanging basket equipment and counterweight beam on the front and rear sides of the main crossbeam respectively. Step 2: When displacement is required, first activate the auxiliary thrust mechanism to lift the support seat upward and separate the support seat from the track. At the same time, the auxiliary thrust mechanism provides forward auxiliary thrust. Step 3: Start the traveling mechanism to apply forward main power to the rear of the support base, driving the support base, main crossbeam and hanging basket equipment to slide forward along the track; Step 4: During the sliding process, the anti-deviation mechanism slides along the guide structure on the side of the track pad beam to limit the lateral deviation of the main crossbeam; Step 5: After sliding to the target position, retract the auxiliary thrust mechanism to allow the support to fall back onto the track, and lock the anti-deviation mechanism.

[0015] The beneficial effects of this invention are as follows: 1. In this invention, a traveling mechanism is set at the rear of the support base. The traveling mechanism acts as the main thrust for the support base and the main crossbeam, enabling the support base and the main crossbeam to move forward. An auxiliary thrust mechanism is set at the bottom of the support base. The auxiliary thrust mechanism acts as an auxiliary thrust for the support base and the main crossbeam, enabling the support base and the main crossbeam to provide forward auxiliary thrust during the traveling process. This not only reduces the thrust load of the traveling mechanism, but also ensures smooth travel of the support base and the main crossbeam during the traveling process.

[0016] 2. In this invention, the main crossbeam is prevented from shifting during movement by setting an anti-deviation mechanism, thus ensuring the stability of the main crossbeam's movement.

[0017] 3. In this invention, after the main crossbeam has completed its displacement, the guide block is locked to fix the position of the electric push rod, thereby reinforcing the main crossbeam and ensuring its stability during operation. Attached Figure Description

Multiple steel rollers 2035 generate forward rotational force during rotation, which drives the support base 3 to perform auxiliary thrust. The hydraulic cylinder 102 provides forward driving force to the support base 3 and main crossbeam 4, and the thrust generated by the hydraulic cylinder 102 serves as the main thrust, driving the support base 3, main crossbeam 4, anchor beam 5, hanging basket device 6, and counterweight beam 7 to move. During the movement, an anti-deviation mechanism prevents the main crossbeam 4 from deviating.

[0022] The principles and spirit of the present invention will be explained in detail below with reference to several representative embodiments.

[0023] The embodiments provided by this invention: like Figures 1 to 9 As shown, a hydraulically assisted push-type hanging basket synchronous sliding device includes: Track pad beam 1, track 2 is installed inside track pad beam 1, support seat 3 is slidably connected inside track 2, main cross beam 4 is fixedly connected above support seat 3, anchor beam 5 is installed on the front side of the top of main cross beam 4, hanging basket device 6 is installed below anchor beam 5, and counterweight beam 7 is installed on the rear side of the top of main cross beam 4. The track beam 1 has a cavity inside, and an auxiliary thrust mechanism is installed inside the cavity. The rear of the support seat 3 is equipped with a traveling mechanism, and both sides of the main crossbeam 4 are equipped with anti-deviation mechanisms during travel. The traveling mechanism includes a hydraulic cylinder base 101, a hydraulic cylinder 102 is fixedly mounted on the top of the hydraulic cylinder base 101, and a mounting plate 103 is fixedly mounted on the output end of the hydraulic cylinder 102. The mounting plate 103 is threadedly connected to the tail of the support base 3. The auxiliary thrust mechanism includes a hydraulic jack 201, which is assembled into the cavity inside the track pad beam 1. A buffer mechanism 202 is fixedly installed at the output end of the hydraulic jack 201, and a sliding device 203 is fixedly installed on the top of the buffer mechanism 202. The anti-deviation mechanism includes an electric push rod 301. The output end of the electric push rod 301 is hinged to both sides of the main crossbeam 4. A guide block 302 is hinged to the end of the electric push rod 301 away from the output end. Guide grooves 303 are provided on both sides of the track pad beam 1. The guide block 302 extends into the interior of the guide groove 303 and is slidably connected to the guide groove 303. The electric push rod 301 extends to provide auxiliary support and guidance for the main crossbeam 4.

[0024] In this embodiment, the support base 3 is slidably installed into the track 2 inside the track pad beam 1. After the main crossbeam 4, anchor beam 5, hanging basket device 6, and counterweight beam 7 are assembled, the hydraulic jack 201 drives the buffer mechanism 202 and the sliding device 203 to lift them. During the lifting process, the sliding device 203 contacts the bottom of the support base 3, and the support base 3 separates from the track 2. Multiple sets of hydraulic jacks 201 and sliding devices 203 lift the support base 3, the main crossbeam 4, and the hanging basket device 6. During this process, the support base 3 is supported by steel rollers 2035. The mounting plate 103 is threaded to the tail of the support base 3, and the hydraulic cylinder 102 provides forward driving force to the support base 3 and the main crossbeam 4. During this process, the auxiliary thrust mechanism drives the support base 3 and the main crossbeam 4 to push forward. The guide block 302 extends into the guide groove 303 and slides in connection with the guide groove 303. When the main crossbeam 4 is lifted, the electric push rod 301 will drive the guide block 302 to slide, so that the guide block 302 is always inside the guide groove 303. When the main crossbeam 4 moves laterally, the guide block 302 slides inside the guide groove 303 and is limited inside the guide groove 303, so that the left and right sides of the main crossbeam 4 can be supported by the electric push rod 301 and the guide block 302, preventing the main crossbeam 4 from shifting during the movement.

[0025] In an optional embodiment, the sliding device 203 includes a main frame 2031. Multiple pulleys 2032 are rotatably connected inside the main frame 2031. The pulleys 2032 are evenly divided into multiple groups, with two pulleys 2032 stacked in each group. Adjacent groups of pulleys 2032 are driven by a belt 2032 to form a staggered distribution between belts. A motor 2034 is fixedly installed on the outside of the main frame 2031. One of the pulleys 2032 is fixedly connected to the output end of the motor 2034. Multiple steel rollers 2035 are fixedly installed at the center of each of the multiple pulleys 2032. Anti-slip particles are provided on the outside of each of the multiple steel rollers 2035. The other end of each steel roller 2035 is rotatably connected to the other side inside the main frame 2031 via a bearing 2036.

[0026] In an optional embodiment, the buffer mechanism 202 includes an upper pressure plate 2021 and a lower pressure plate 2022. A plurality of buffer springs 2023 are distributed between the upper pressure plate 2021 and the lower pressure plate 2022. Each of the plurality of buffer springs 2023 is provided with a damper 2024 inside, and the damper 2024 is connected to the upper pressure plate 2021 and the lower pressure plate 2022.

[0027] In an optional embodiment, a base plate 204 is fixedly connected to the bottom of the hydraulic jack 201, and multiple limiting strips 205 are fixedly connected inside the track pad beam 1. The multiple limiting strips 205 are in pairs, and a restriction area is formed between two limiting strips 205. The base plate 204 extends into the interior of the restriction area and is set between each set of limiting strips 205. The base plate 204 is limited by each set of limiting strips 205. There is no gap between the base plate 204 and each set of limiting strips 205. When the base plate 204 is under load, the limiting effect of the limiting strips 205 prevents the base plate 204 from shifting or misaligning.

[0028] In an optional embodiment, locking shafts 304 are fixedly connected to both sides of the guide block 302. Locking rings 305 are threadedly connected to the outside of the locking shafts 304. A sliding cavity 306 is provided on the outer side of the track pad beam 1. The locking shafts 304 pass through the interior of the sliding cavity 306 to slide within the sliding cavity 306. By rotating the locking ring 305, the locking ring 305 is pressed against the support seat 3 to stabilize the position of the guide block 302 after movement.

[0029] In an optional embodiment, the hanging basket device 6 includes a steel rope 61, the bottom of which is fitted with a hanging mechanism 62, and the bottom of the hanging mechanism 62 is fixedly connected to a lower crossbeam 63.

[0030] In an optional embodiment, the tethering mechanism 62 includes a lug 621 and an anti-detachment hook 622, the anti-detachment hook 622 being fixedly connected to the bottom of the steel rope 61, and the lug 621 being welded to the top of the lower crossbeam 63.

[0031] In an optional embodiment, a buckle 8 is provided at the bottom of the counterweight beam 7, and a counterweight block 9 is engaged inside the buckle 8.

[0032] In an optional embodiment, the counterweight beam 7 is made of concrete, and the counterweight block 9 is also made of concrete.

[0033] One end of multiple steel rollers 2035 is fixedly connected to multiple pulleys 2032, and the other end of multiple steel rollers 2035 is rotatably connected to the inside of the main frame 2031 through bearings 2036. Multiple steel rollers 2035 contact the bottom of the support base 3, and are driven by multiple pulleys 2032 through motor 2034, so that multiple steel rollers 2035 generate forward rotational force, thereby achieving the purpose of providing auxiliary thrust to the support base 3.

[0034] The upper pressure plate 2021 is fixedly connected to the output end of the hydraulic jack 201, and the lower pressure plate 2022 is fixedly connected to the bottom of the main frame 2031. When the main frame 2031 is under load, the buffer spring 2023 contracts and the damper 2024 reduces the vibration energy to prevent deformation of the main frame 2031 and the steel roller 2035 inside the main frame 2031.

[0035] The lower crossbeam 63 is connected to the hanging mechanism 62 via steel rope 61. The anti-detachment hook 622 is attached to the lifting lug 621. After the lower crossbeam 63 is assembled, the anti-detachment hook 622 and the lifting lug 621 are disassembled, and then the lifting lug 621 is cut.

[0036] During the movement of the main crossbeam 4, the locking shaft 304 will slide inside the sliding cavity 306. After the main crossbeam 4 has completed its movement, the locking ring 305 is threaded to the outside of the locking shaft 304. The locking ring 305 contacts the outer wall of the track pad beam 1, thereby fixing the guide block 302 inside the guide groove 303.

[0037] A method for synchronous sliding of a hydraulically assisted push-type hanging basket, employing the aforementioned hydraulically assisted push-type hanging basket synchronous sliding device, includes the following operating steps: Step 1: After the construction of the No. 0 block of the bridge is completed, two sets of track pad beams 1 are installed on the front and rear sides of the No. 0 block base to make the front and rear sides of the No. 0 block base balanced. The track pad beams 1 are adapted to the track 2. The support seat 3 and the main crossbeam 4 are slidably connected to the inside of the track pad beams 1 through the track 2. The front side of the main crossbeam 4 is equipped with a hanging basket device 6 through the anchor beam 5, and the rear side of the main crossbeam 4 is stabilized by the counterweight beam 7. Step 2: As shown in Step 1, when the support base 3, main crossbeam 4, and hanging basket device 6 need to be displaced, the hydraulic jack 201 first drives the buffer mechanism 202 and sliding device 203 to lift them. During the lifting process, the sliding device 203 contacts the bottom of the support base 3. Multiple sets of hydraulic jacks 201 and sliding devices 203 lift the support base 3, main crossbeam 4, and hanging basket device 6. Then, the mounting plate 103 is threaded to the tail of the support base 3. The hydraulic cylinder 102 provides forward driving force to the support base 3 and main crossbeam 4. During this process, the auxiliary thrust mechanism drives the support base 3 and main crossbeam 4 to perform auxiliary forward pushing. Step 3: As shown in Step 2, one end of the multiple steel rollers 2035 is fixedly connected to multiple pulleys 2032, and the other end of the multiple steel rollers 2035 is rotatably connected to the inside of the main frame 2031 through bearings 2036. The multiple steel rollers 2035 contact the bottom of the support base 3, and the multiple pulleys 2032 are driven by the motor 2034 to generate forward rotational force, thereby achieving the purpose of providing auxiliary thrust to the support base 3. Step 4: As shown in Step 2, when the main frame 2031 is under load, the buffer spring 2023 contracts and the damper 2024 reduces the vibration energy to prevent deformation of the main frame 2031 and the steel roller 2035 inside the main frame 2031. Step 5: As shown in Step 1, after the bottom membrane of Block 1 of the bridge is poured, the lower crossbeam 63 is fixed to the bottom membrane of Block 1 of the bridge by steel rope 61 and tethering mechanism 62, so that Block 0 of the bridge can be connected with Block 1, and so on, so that Block 0, Block 1, Block 2 and Block 3 of the bridge can be connected.
