Description

Technical Field

[0001] The utility model relates to the technical field of bridge pier maintenance, in particular to a bridge pier body spray maintenance device. Background Art

[0002] Concrete has become an important material in modern construction projects due to its abundant raw material resources, excellent plasticity, high-strength mechanical properties, simple construction technology and low production costs. The ultimate performance of concrete structures is not only determined by the pouring process, but also by subsequent maintenance work, which is specifically done by keeping the concrete surface moist to ensure the smooth progress of the hydration reaction. If the maintenance measures are not in place, the concrete surface will lose water, causing the hydration reaction to terminate, and then shrinkage cracks will occur, affecting the structural strength.

[0003] During bridge construction, piers, as key components supporting the bridge's superstructure, require particularly critical concrete curing. Currently, pier concrete curing is performed using spray curing equipment, including fixed and mobile spray curing methods. Fixed curing involves wrapping the pier from top to bottom with geotextiles or film, and spraying with branch pipes fixed above the pier. Mobile curing utilizes a winch to move a circular lifting frame up and down, enabling multi-angle spray curing.

[0004] Current pier spray maintenance equipment consists of circumferentially distributed spray pipes installed at the top of the pier and a ground-mounted water tank, connected by a water pipe. During installation, the spray pipes are typically located at the top of the pier. Fixed maintenance methods make it difficult to effectively spray the middle and lower areas of taller piers. Mobile maintenance methods utilize a winch to retract and unwind cables to achieve vertical movement of a circular hoist. However, as the pier height increases, its lifting stability decreases, posing a safety hazard.

[0005] The information disclosed in this background technology section is only intended to deepen the understanding of the overall background technology of the present disclosure and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art known to those skilled in the art.

DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0037] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly attached to the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0039] The present invention addresses some technical problems existing in the current bridge pier concrete curing methods, especially those related to the equipment stability and safety of high pier curing. By optimizing the curing equipment structure, the equipment stability and safety are further enhanced, while the equipment installation process is simplified, thereby improving the curing quality and efficiency of bridge pier concrete.

[0040] In this application, see Figures 1 to 6 The bridge pier body spray maintenance device shown includes a support frame 1 and a lifting frame 2 and a power assembly 3 arranged thereon. The lifting frame 2 is driven to move in the vertical direction by the power assembly 3; the lifting frame 2 is arranged in a ring shape on the outer ring of the pier, and a spray assembly 5 is provided on the lifting frame 2. The spray assembly 5 is connected to the water tank 53 through a water supply assembly 54; the support frame 1 is arranged vertically and extends to the top of the pier. The lifting frame 2 is slidably connected to the support frame 1, and a locking assembly 4 is provided at the top of the support frame 1 corresponding to the lifting frame 2.

[0041] The lifting frame 2 is annularly positioned around the outer ring of the pier, enabling the spray assembly 5 mounted thereon to spray the pier in all directions. The power assembly 3 drives the lifting frame 2 vertically, spraying the pier in all directions along its entire height, ensuring that all surfaces receive adequate care. A sliding connection between the lifting frame 2 and the support frame 1 ensures its stability during mobile spraying maintenance. A locking assembly 4 is installed between the lifting frame 2 and the support frame 1 to ensure safety during stationary spraying maintenance.

[0042] During the specific implementation process, the bridge pier is first wrapped with geotextile and plastic film from top to bottom, and then the support frame 1 and the lifting frame 2 are erected; when the spray curing device is erected, the lifting frame 2 is first driven by the power component 3 to move in the vertical direction and spray water to the pier body, so that the geotextile and plastic film are completely soaked and fully fit the surface of the pier body; then the lifting frame 2 is driven by the power component 3 to move to the top of the support frame 1, and is locked and fixed with the locking component 4, so that the spray component 5 continues to spray water to the top of the pier body; at this time, the geotextile is maintained in a moist state, so that the moisture in it forms a self-flowing water curtain under the action of gravity and is transferred to the plastic film, thereby continuously maintaining the overall moist state of the pier body surface.

[0043] The wrapping of geotextile and plastic film forms an effective moisture-retaining barrier, reducing the evaporation of water on the surface of the pier body. The gravity water curtain is then used to keep the pier body moist, which improves the maintenance efficiency, reduces the waste of water resources, and improves the uniformity of maintenance.

[0044] In this embodiment, if Figure 2 and Figure 3 As shown, the support frame includes a horizontal base frame 11 and a vertical base frame 12. The horizontal base frame 11 is arranged on the top of the pier, and the vertical base frames 12 are relatively arranged on both sides of the horizontal base frame 11. The power assembly 3 is arranged on the horizontal base frame 11, and the lifting frame 2 is slidably connected to the vertical base frame 12.

[0045] Both the horizontal base frame 11 and the vertical base frame 12 adopt a modular design, and the two are fixed by standardized connection methods, such as bolt connection or clamp connection, making the assembly and disassembly process of the overall support frame 1 simple and quick, which is conducive to shortening the installation and disassembly time of the spray maintenance equipment.

[0046] Among them, the horizontal base frame 11 includes a horizontal beam 111 and a longitudinal beam 112 arranged perpendicular to each other. There are multiple longitudinal beams 112 arranged in parallel and fixedly connected through the horizontal beam 111. There are at least two horizontal beams 111 and they are respectively located at both ends of the length of the longitudinal beam 112; the vertical base frame 12 includes a vertical rod 121, a horizontal rod 122 and a limit rod 123. There are multiple vertical rods 121 arranged in parallel and fixedly connected through the horizontal rod 122. The limit rod 123 is vertically arranged and fixedly connected to the horizontal rod 122.

[0047] The cross beams 111 and longitudinal beams 112 in the horizontal base frame 11 can be flexibly adjusted according to the actual size of the bridge piers. By increasing or decreasing the number of longitudinal beams 112 or adjusting the length of the cross beams 111, the support frame 1 can adapt to bridge piers of different cross-sectional sizes; the vertical rods 121, cross rods 122 and limit rods 123 in the vertical base frame 12 can also be combined and adjusted as needed to adapt to bridge piers of different heights.

[0048] This embodiment improves the convenience of installation through the modular support frame 1 structure, and the flexible assembly of each support frame 1 module further enhances the wide applicability of the support frame 1; it not only improves construction efficiency and quality, but also reduces costs and maintenance difficulty, and has broad promotion value and application prospects.

[0049] As a preferred embodiment of the above, Figure 2 and Figure 6 As shown, the lifting frame 2 is located between the two vertical base frames 12 and is slidably connected to the limiting rod 123 through a sliding seat 27. The limiting rod 123 is located on the side of the cross bar 122 facing the lifting frame 2; the limiting rod 123 is configured as a rectangular column, and the sliding seat 27 includes a U-shaped support 271 and three limiting wheels 272 respectively provided on its three mounting surfaces. The three limiting wheels 272 are respectively in rolling connection with the three outer walls of the limiting rod 123.

[0050] The lifting frame 2 is slidably connected to the limiting rod 123 through the sliding seat 27. The limiting rod 123 serves as a sliding track to provide stable support and guidance, ensuring the stability of the lifting frame 2 in the vertical movement; the three limiting wheels 272 on the U-shaped support 271 in the sliding seat 27 are respectively rollingly connected to the three outer walls of the limiting rod 123. The three-point contact design enhances the stability of the sliding connection, while preventing the lifting frame 2 from shaking or deflecting in any direction in the horizontal plane during movement, further enhancing the stability and safety of the lifting frame 2 during displacement.

[0051] In this embodiment, if Figure 2 and Figure 5 As shown, the lifting frame 2 includes an inner ring rod 21, an outer ring rod 22 and a lower ring rod 23. The inner ring rod 21 and the outer ring rod 22 are located in the same horizontal plane, and the lower ring rod 23 is located below the inner ring rod 21 and the outer ring rod 22; the inner ring rod 21 and the outer ring rod 22 are fixedly connected to the lower ring rod 23 by alternately arranged first oblique rods 24 and second oblique rods 25. The first oblique rods 24 and the second oblique rods 25 are arranged at a fixed angle, and multiple are provided along the circumference of the lifting frame 2.

[0052] Furthermore, the inner ring rod 21, the outer ring rod 22 and the lower ring rod 23 are arranged in an inverted triangle, and cooperate with the first oblique rod 24 and the second oblique rod 25 to form a placement groove 26; the cross-section of the placement groove 26 is an inverted triangle structure, and the spray assembly 5 includes a water spray pipe 51 and a plurality of nozzles 52 arranged in its length direction. The water spray pipe 51 is arranged in the placement groove 26, and the water supply assembly 54 includes a water supply pipe 541 and a water pump 542 connected to the water spray pipe 51.

[0053] The inverted triangle arrangement structure of the inner ring rod 21, the outer ring rod 22 and the lower ring rod 23 not only enhances the structural stability of the lifting frame 2, but also provides a stable installation space for the water pipe 51 and the nozzle 52; among them, the first inclined rod 24 and the second inclined rod 25 increase the overall rigidity of the lifting frame 2.

[0054] In this embodiment, if Figure 2 and Figure 4 As shown, the power assembly 3 includes a motor 31, a first transmission assembly 32 and a second transmission assembly 33. Four second transmission assemblies 33 are provided and are respectively arranged at four positions of the lifting frame 2. The second transmission assembly 33 is connected to the lifting frame 2. The motor 31 synchronously drives the four second transmission assemblies 33 through the first transmission assembly 32.

[0055] The first transmission assembly 32 includes two transmission shafts 321 arranged in parallel. The motor 31 synchronously drives the two transmission shafts 321 to rotate through two first pulley 322a assemblies 322. The transmission shaft 321 is fixed to the top of the support frame 1 through the first bearing seat 323. The four second transmission assemblies 33 include four second pulley 322b assemblies arranged at both ends of the length of the two transmission shafts 321.

[0056] Specifically, the first transmission assembly 32 also includes a first pulley 322a and a second pulley 322b respectively arranged on the output shaft of the motor 31 and the transmission shaft 321, and a first synchronous belt 322c sleeved on the first pulley 322a and the second pulley 322b; the second transmission assembly 33 includes a third synchronous wheel 331a and a fourth synchronous wheel 331b, and a second synchronous belt 331c sleeved thereon, the third synchronous wheel 331a is arranged on the transmission shaft 321, and the fourth synchronous wheel 331b is arranged on the second bearing seat 331d and is located directly below the third synchronous wheel 331a; a connecting seat 28 is provided on the lifting frame 2, and the connecting seat 28 is fixedly connected to the second synchronous belt 331c through a clamping sleeve 281 provided thereon.

[0057] Two transmission shafts 321 are secured to the top of the support frame 1 via first bearing blocks 323. A motor 31, acting as a power source, synchronously drives the two parallel transmission shafts 321 via two first pulley assemblies 322a, ensuring synchronized and stable power transmission. Four second transmission assemblies 33 are connected to the four positions of the lifting frame 2, further enhancing the smoothness of the overall vertical movement of the lifting frame 2.

[0058] In this embodiment, see Figure 3 and Figure 5As shown, the locking assembly 4 includes a limit seat 41 arranged on the lifting frame 2, a limit hole 411 is opened on the limit seat 41, a first through hole 42 is opened on the longitudinal beam 112 corresponding to the limit hole 411, and a second through hole 43 is opened at the top of the limit rod 123 corresponding to the sliding seat 27, and a connecting bolt and a positioning pin are respectively provided in the first through hole 42 and the second through hole 43.

[0059] When the lifting frame 2 moves to the top of the support frame 1, it is locked and fixed by the locking assembly 4. Specifically, after the limiting hole 411 on the limiting seat 41 is close to and aligned with the first through hole 42 on the longitudinal beam 112, a connecting bolt is inserted to tighten it; when the second through hole 43 at the top of the limiting rod 123 is close to the bottom surface of the sliding seat 27, the bottom surface of the sliding seat 27 is supported by the pin in the second through hole 43, thereby limiting the vertical position of the entire lifting frame 2.

[0060] The double locking of the connecting bolts and the positioning pins ensures the stability of the lifting frame 2 during the fixed spray curing process, avoiding the situation where the lifting seat is deflected and unstable due to shaking caused by external forces.
