Description

Technical Field

[0001] This invention relates to the field of pier maintenance, and in particular to a device for installing cotton-padded clothing for pier maintenance and its installation method. Background Technology

[0002] In winter construction and maintenance of bridge piers, to prevent concrete from freezing and ensure normal hydration, it is usually necessary to wrap and insulate the piers with protective cotton coverings. Existing protective cotton coverings are mostly made of flexible materials, including a top protective cap and an integrally formed pier body protective cover, with vertical openings on the pier body cover to wrap the pier from the side. However, because the protective cotton covering is a large-sized flexible structure with low rigidity, it is prone to deformation and swaying during installation. Traditional installation methods typically require lifting equipment to hoist the protective cotton covering while multiple workers use ropes to pull and stretch the sides of the openings for alignment. This human-machine collaborative operation mode is not only labor-intensive and inefficient, but also difficult to maintain stability in severe weather conditions such as strong winds, making installation extremely difficult or even impossible. Therefore, this paper proposes a pier protective cotton covering installation device and its installation method to solve the above problems. Summary of the Invention

[0003] The main objective of this invention is to provide a device and method for installing cotton-padded clothing for pier maintenance, which solves the problems of high labor costs and low installation efficiency in traditional operation modes, as well as the difficulty in maintaining a stable posture due to the large wind-exposed area of ​​the flexible cover when encountering severe weather conditions such as strong winds, making the installation operation extremely difficult or even impossible.

[0014] This invention provides a device and method for installing a flexible protective cotton-padded garment on a pier. The device constructs a rigid "exoskeleton" installation structure on the outside of the flexible protective cotton-padded garment, fundamentally changing the traditional operation mode that relies on manual assistance to hoist the flexible cover. This significantly improves construction efficiency and environmental adaptability. The "exoskeleton" structure uses a rigid frame to provide a stable support skeleton for the flexible protective cotton-padded garment, enabling it to maintain a preset unfolded shape during hoisting. This effectively overcomes the defects of large-sized flexible materials, such as easy swaying, easy deformation, and large wind-exposed area. It enables precise, stable, and rapid positioning even in adverse weather conditions such as wind. This greatly reduces the reliance on rope traction and coordination by multiple workers, lowering labor costs and the risks of high-altitude operations. At the same time, the automatic closure problem of the opening and closing joints is solved by rotating the outward connecting belt, connecting frame, and various opening and closing control parts.

Detailed Implementation

[0017] like Figure 1-14 As shown, a device for installing a protective covering for a pier column includes a pier column 3 and a protective covering 1 to be fitted over the pier column 3. In this embodiment, the pier column 3 is cylindrical, and the size of the protective covering 1 is adapted to the size of the pier column 3. Specifically, it includes a top protective cap 10 and a pier body protective cover 11. The top protective cap 10 is designed to be fitted onto the top of the pier column 3, and the pier body protective cover 11 is connected to the bottom of the cap and integrally formed with it. To achieve the covering installation of the pier column 3, the pier body protective cover 11 has an opening and closing slit 110 in the vertical direction. During construction, the pier body protective cover 11 can be unfolded through the opening and closing slit 110 and wrapped around the outer periphery of the pier column 3. The above structure is a conventional technical means in this field and will not be described in detail here.

[0018] In this embodiment, a sealing strip 111 is provided on one side of the opening and closing joint 110 of the pier body maintenance cover 11. The inner side of the sealing strip 111 and the outer side of the other side of the opening and closing joint 110 are respectively provided with mutually cooperating hook and loop fastener surfaces 112 and hook and loop fastener surfaces 113. Thus, after the pier body maintenance cover 11 is installed on the outside of the pier column 3, the opening and closing joint 110 can be sealed by the fastening of the hook and loop fastener surfaces 112 and 113.

[0019] Because the maintenance cotton garment 1 is a large-sized flexible structure with low rigidity, it is prone to deformation or swaying during hoisting. In existing technology, it is typically necessary to use lifting equipment to raise the maintenance cotton garment 1 while multiple construction workers use ropes to pull and tension the maintenance cover 11 on both sides of the joint 110 to assist in alignment and installation. This method is not only labor-intensive and inefficient, but also makes it difficult to maintain a stable posture under complex weather conditions such as wind, as the flexible cover has a large wind-exposed area, potentially making installation impossible.

[0020] In view of the problems of installation difficulties and poor environmental adaptability in the existing technology, this embodiment provides an installation device 2 to realize the installation of the maintenance cotton coat 1.

[0021] The installation device 2 includes a top lifting part 20 that is fitted onto the outside of the top maintenance cap 10. The bottom of the top maintenance cap 10 is connected to a plurality of opening and closing control parts 22 via a connecting frame 21. The opening and closing control parts 22 are fitted onto the outside of the pier body maintenance cover 11 in sequence and are used to control the opening and closing of the opening and closing joint 110.

[0022] In order to enable the maintenance cotton coat 1 to be connected to the installation device 2, the top maintenance cap 10 and the outside of the pier maintenance cover 11 are both provided with connecting straps 12.

[0023] Meanwhile, both the top lifting part 20 and the opening and closing control part 22 are provided with clamping connecting parts 23 for clamping the connecting belt 12 at their bottoms.

[0024] Specifically, the top maintenance cap 10 is provided with a set of connecting straps 12 connected to the top lifting part 20. The top maintenance cap 10 is provided with the same number of connecting straps 12 as the opening and closing control part 22. The circumferential positioning of the connecting straps 12 satisfies the effect of controlling the opening and closing of the opening and closing seam 110. In this embodiment, there are four opening and closing control parts 22, which are equidistantly distributed. Due to structural limitations, the opening and closing angle at the top of the opening and closing seam 110 is small, and the significance of opening and closing control is small. Therefore, the uppermost opening and closing control part 22 is located in the upper middle position of the opening and closing seam 110. At the same time, the opening and closing degree of each opening and closing control part 22 is adjusted according to its position to avoid tearing of the maintenance cotton coat 1.

[0025] In the preferred embodiment, the opening and closing control unit 22 specifically includes a fixed arc-shaped seat 220, with opening and closing arc-shaped arms 221 hinged at both ends of the fixed arc-shaped seat 220. When the two opening and closing arc-shaped arms 221 are combined, they can form a closed mechanism that is adapted to the shape of the pier 3 with the fixed arc-shaped seat 220. The ends of the two opening and closing arc-shaped arms 221 are located on both sides of the opening and closing joint 110. It should be noted that when the fixed arc-shaped seat 220 is closed, it will not form a clamping and locking relationship with the pier 3.

[0026] It should be noted that the bottom of the opening and closing control unit 22 is provided with three clamping connecting parts 23. The three clamping connecting parts 23 are respectively located at the bottom of the fixed arc-shaped base 220 and the two opening and closing arc-shaped arms 221. The position of the connecting strip 12 corresponds to it, and the opposite end of the connecting strip 12 located at the bottom of the two opening and closing arc-shaped arms 221 is close to the opening and closing seam 110. Thus, the opening and closing control of the opening and closing seam 110 can be realized by opening and closing the two opening and closing arc-shaped arms 221.

[0027] To control the opening and closing of the arc-shaped arm 221, a first hinge seat 222 extending outward is provided at the center of the outer side of the fixed arc-shaped seat 220. A second hinge seat 223 extending outward is provided on the outer side of the end of the arc-shaped arm 221 near the fixed arc-shaped seat 220. An opening and closing telescopic cylinder 224 is hinged between the second hinge seat 223 and the first hinge seat 222. The opening and closing of the corresponding arc-shaped arm 221 can be controlled by the extension and retraction of the opening and closing cylinder 224, thereby controlling the opening and closing of the opening and closing seam 110. The opening and closing telescopic cylinder 224 is preferably a hydraulic cylinder.

[0028] To achieve the effect of automatically closing the sealing strip 111, a receiving groove 2210 is provided on the inner side of the end of the opening and closing arc arm 221 corresponding to the sealing strip 111, and a temporary adhesive surface 2211 corresponding to the hook and loop surface 112 or hook and loop surface 113 is provided on the inner wall of the receiving groove 2210, so that the sealing strip 111 is in the open state in the receiving groove 2210 and is attached to the temporary adhesive surface 2211. This state is maintained to prevent unnecessary adhesion of the sealing strip 111 during the process of closing the opening and closing joint 110 by the opening and closing control part 22, which would affect the closing of the opening and closing joint 110.

[0029] The connecting frame 21 is fixed on the fixed arc-shaped seat 220 of each opening and closing control part 22, thereby avoiding affecting the opening and closing of the opening and closing arc arm 221. At the same time, the connecting frame 21 is rotatably set at the bottom of the top lifting part 20. With this design, the rotation of the connecting frame 21 can drive the rotation of all the opening and closing control parts 22 in the closed state, thereby driving the sealing strip 111 to flip towards the bonding side and detach it from the temporary adhesive surface 2211. Under the pressing action of the inner side of the opening and closing arc arm 221, the hook and loop surface 112 and the hook and loop fabric surface 113 are bonded together.

[0030] Specifically, the top lifting part 20 includes a ring 200 that can be fitted onto the outside of the top maintenance cap 10. The ring 200 has multiple lifting lugs 201 for lifting and two connecting seats 202. In this embodiment, the number of lifting lugs 201 is four arranged in a ring array on the outside of the ring 200, which facilitates the connection of the lifting device. The connecting seats 202 are L-shaped, and a rotating guide rod 203 is connected between their bottoms. The length of the rotating guide rod 203 meets the above-mentioned rotation distance requirements. The top of the connecting frame 21 is U-shaped and is slidably mounted on the rotating guide rod 203. An arc-shaped rack 210 is provided on the outer side of the top crossbeam of the connecting frame 21. A driving device 204 is provided on the outside of the connecting seat 202. The driving device 204 is composed of a motor and a reducer. A transmission gear 205 is installed on the output shaft of the driving device 204, and the transmission gear 205 meshes with the arc-shaped rack 210.

[0031] With this design, the transmission gear 205 can be driven to rotate by the drive device 204, thereby driving the connecting frame 21 and its opening and closing control part 22 to rotate by meshing with the arc rack 210. It should be noted that the installation positions of the drive device 204 and the arc rack 210 meet the above-mentioned rotation requirements.

[0032] In this embodiment, the clamping connection part 23 specifically includes a clamping telescopic cylinder 230 built into the opening and closing control part 22 or the ring body 200. The telescopic end of the clamping telescopic cylinder 230 moves through the opening and closing control part 22 or the ring body 200 and is connected to a clamping plate 231. The clamping plate 231 can be telescopically extended and extended to clamp the connecting strap 12 between itself and the bottom of the opening and closing control part 22 or the ring body 200.

[0033] In the preferred embodiment, in order to avoid the opening and closing telescopic cylinder 224 needing to output thrust for a long time after the two opening and closing arc arms 221 have closed, a locking mechanism is provided at the docking end of the two opening and closing arc arms 221 to lock each other.

[0034] The locking mechanism specifically includes a mounting base 225 and a locking base 226 respectively disposed on the outer sides of the ends of the two opening and closing arc-shaped arms 221. An electric screw-type telescopic cylinder 228 is fixedly mounted on the mounting base 225. The telescopic end of the electric screw-type telescopic cylinder 228 moves through the mounting base 225 and connects to the locking part 229. The locking base 226 has an open structure on the side near the mounting base 225, and locking blocks 227 are symmetrically arranged on its two opposite inner wall surfaces. The locking part 229 can be inserted into the locking base 226 and form a locking engagement structure with the locking blocks 227.

[0035] The locking part 229 includes a housing 2290, in which an inner cavity 2291 with openings at both ends is provided. An electromagnet 2292 is provided in the middle of the inner cavity 2291. A telescopic spring 2293 is provided at both ends of the electromagnet 2292. The other end of the telescopic spring 2293 is connected to a locking block 2294 that can pass through the opening. The locking block 2294 is configured to extend outward from the openings at both ends of the inner cavity 2291 under the elastic restoring force of the telescopic spring 2293 in its natural state, and to retract inward under the magnetic pull of the electromagnet 2292 when the electromagnet 2292 is energized to release the lock. The magnetic circuit of the electromagnet 2292 only acts on the locking block 2294. Limiting grooves 2295 are symmetrically provided on the opposite inner wall surfaces of the inner cavity 2291. A limiting block 2296 that slides with the limiting groove 2295 is provided at the inner end of the locking block 2294.

[0036] The protruding end of the locking block 2294 and the corresponding surface of the locking block 227 are respectively provided with mutually adapted wedge-shaped slopes; the wedge-shaped slopes are constructed such that when the locking block 2294 moves with the device and initially abuts against the locking block 227, the inclined force forces the locking block 2294 to overcome the spring force and retract axially to make room; after the locking block 2294 slides past the locking block 227, it automatically resets and pops out under the action of the telescopic spring 2293, thereby forming a locking engagement with the locking block 227.

[0037] With this design, after the two opening and closing arc arms 221 are closed, the locking part 229 can be pushed into the locking seat 226 by the electric screw telescopic cylinder 228, and a locking engagement can be formed with the locking block 227. When unlocking is required, the locking block 2294 can be retracted by the electromagnet 2292, and the electric screw telescopic cylinder 228 can be retracted.

[0038] In another embodiment, in conjunction with the pier maintenance cotton-padded clothing installation device proposed in the above embodiments, an installation method for the pier maintenance cotton-padded clothing installation device is proposed, the method comprising: S1. On the ground, put the maintenance cotton coat 1 into the installation device 2, so that each connecting strap 12 corresponds to the clamping connection part 23 of the top lifting part 20 and the pier body maintenance cover 11, and make the clamping connection part 23 clamp the corresponding connecting strap 12. At the same time, flip the connecting strap 12 and stick it on the temporary adhesive surface 2211. At this time, the installation device 2 forms an "exoskeleton" structure on the outside of the maintenance cotton coat 1.

[0039] S2. Connect the lifting rope of the lifting device to the lifting lug 201 on the top lifting part 20, lift the installation device 2 and the maintenance cotton coat 1 connected inside it, and keep it vertical. Then, through the opening and closing of each opening and closing control part 22, the opening and closing seam 110 of the maintenance cotton coat 1 is opened. At this time, the installation device 2 can prevent the maintenance cotton coat 1 from swinging irregularly.

[0040] It should be noted that the opening and closing angles of each opening and closing control unit 22 increase sequentially from top to bottom.

[0041] S3. The maintenance cotton coat 1 is hoisted onto the pier 3 by the hoisting device, so that the top maintenance cap 10 is fitted onto the top of the pier 3, and the pier body enters the pier body maintenance cover 11 through the open opening and closing seam 110.

[0042] S4. Close each opening and closing control part 22 to close the opening and closing seam 110. Then, disconnect the opening and closing control part 22 from each connecting strip 12. Drive the connecting frame 21 and all opening and closing control parts 22 to rotate through the driving device 204. After the connecting strip 12 is flipped and pressed, the initial bonding is completed.

[0043] S6. Disconnect the top lifting part 20 from each connecting belt 12, and use the lifting device to lift the installation device 2 upwards. The height should be the same as the distance between each opening and closing control part 22. Then, by rotating the rear opening and closing arc arm 221 to press the connecting belt 12 together, the overall bonding of the connecting belt 12 is completed.

[0044] S7. Finally, open all opening and closing control parts 22, and after the top lifting part 20 is separated from the top maintenance cap body 10 and the pier 3, the installation device 2 can be horizontally lifted and moved.

[0045] The above embodiments are merely preferred technical solutions of the present invention and should not be considered as limitations on the present invention. The scope of protection of the present invention should be limited to the technical solutions described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the scope of protection of the present invention.
