Modular Collaborative Repair Workstation for Shore-based Mobile Concrete Lining Panels Technical Field
[0001] This utility model relates to the field of channel repair technology, specifically to a modular collaborative repair workstation for movable concrete lining slabs on the shore under flowing water conditions. Background Technology
[0002] The main functions of large canals or waterways include water supply, irrigation, ecological environment improvement, and promoting economic and social development. They not only ensure the effective use of water resources but also promote the comprehensive development of the region. During long-term operation, the slopes of large canals or waterways are affected by numerous factors such as groundwater levels, freeze-thaw cycles, construction quality, and external forces. This can lead to cracking, collapse, heaving, and buoyancy instability of the concrete lining slabs on the canal or waterway slopes, adversely affecting the structural safety and water supply capacity of the canals or waterways. Damage to the concrete lining slabs on the canal or waterway slopes can cause softening of the slope soil, leading to slope instability. Therefore, it is necessary to promptly remove and repair damaged concrete lining slabs to ensure the normal and safe water supply of the canals or waterways.
[0003] Existing equipment for constructing and repairing concrete lining slabs in channels or rivers under flowing water conditions is used to repair underwater damaged lining slabs. This equipment includes a gantry frame set up on the riverbank. However, existing gantry frames generally consist of two upright columns and a horizontal column connecting the tops of the two upright columns. Both the upright columns and the horizontal column are composed of single columns, resulting in relatively poor structural stability. This cannot meet the support requirements for using equipment for constructing and repairing concrete lining slabs in channels or rivers under flowing water conditions. Summary of the Invention
[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a modular collaborative repair workstation for shore-based mobile concrete lining slabs, in order to solve the problem that existing gantry frames cannot meet the stability requirements of equipment for the construction and repair of concrete lining slabs in channels or rivers under flowing water conditions.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a modular collaborative repair workstation for shore-based mobile concrete lining slabs, comprising a gantry frame body, wherein the gantry frame body comprises two support frames and a connecting frame body connected between the two support frames, and both support frames and the connecting frame body adopt a truss structure.
[0006] Compared with the prior art, the present invention has the following beneficial effects:
[0007] Both of the aforementioned support frames and connecting frames in this onshore equipment adopt truss structures, which can reduce self-weight by 30%-50% compared to solid web beam structures, thereby reducing the difficulty of transportation and hoisting and the energy consumption of the drive system. While ensuring the lightweight structure, it forms a multi-directional force system, effectively suppressing bending, shearing and torsional deformation, ensuring the overall structural rigidity of the gantry frame, and meeting the usage requirements. Attached Figure Description
[0008] Figure 1 is a structural schematic diagram of an embodiment of the present invention.
[0009] The reference numerals in the accompanying drawings include: gantry frame body 1, support frame 11, longitudinal main truss 111, transverse connecting truss 112, connecting frame 12, hoisting and replacement space 13, crawler walking mechanism 14, and winch 2. Detailed Implementation
[0010] The present invention will be further described in detail below through specific embodiments:
[0011] As shown in Figure 1, this utility model embodiment proposes a modular collaborative repair workstation for shore-based mobile concrete lining slabs, including a gantry frame body 1. The gantry frame body 1 includes two support frames 11 and a connecting frame 12 connected between the two support frames 11. Both support frames 11 and the connecting frame 12 adopt a truss structure.
[0012] Both of the aforementioned support frames 11 and connecting frames 12 in the onshore equipment adopt truss structures. Compared with solid web beam structures, they can reduce self-weight by 30%-50%, reduce transportation and hoisting difficulty and drive system energy consumption; while ensuring structural lightweighting, they form a multi-directional force system, effectively suppressing bending, shearing and torsional deformation, ensuring the overall structural rigidity of the gantry frame body 1, and meeting the usage requirements.
[0013] The truss structure is specifically a four-truss structure, which is lightweight and has strong load-bearing capacity. Its main function is to support the moving crossbeams in the underwater repair equipment for the channel concrete lining panel, enabling it to complete the work of replacing the end effector, loading the finished precast panels, and unloading the waste cement panels.
[0014] Both of the aforementioned support frames 11 are used to connect with the truss in the underwater repair equipment for the channel concrete lining panel and are used to go deep underwater, and can share the load on the truss.
[0015] As shown in Figure 1, according to another embodiment of the present invention, the modular collaborative repair workstation for shore-based mobile concrete lining slabs, wherein the connecting frame 12 is located on the rear side within the two supporting frames 11 and forms a hoisting and replacement space 13 on the front side within the two supporting frames 11.
[0016] In this embodiment, the connecting frame 12 is located on the rear side within the two supporting frames 11, which ensures the integrity of the connection between the connecting frame 12 and the supporting frames 11. At the same time, the hoisting and replacement space 13 is formed to allow the moving crossbeam in the underwater repair of the channel concrete lining panel to be moved to the top of the two supporting frames 11, and the end effector suspended on the moving crossbeam is located in the hoisting and replacement space 13 for replacement, so as to continuously perform cutting, removal, trimming, cleaning of gravel, leveling, replacement of new panels and caulking, etc., to complete the underwater repair of the channel concrete lining panel.
[0017] Based on the above solution:
[0018] Each of the support frames 11 includes a longitudinal main truss 111 and a transverse connecting truss 112. There are two longitudinal main trusses 111 arranged at intervals. The connecting center line of the two longitudinal main trusses 111 is perpendicular to the connecting center line of the two support frames 11. One of the longitudinal main trusses 111 is connected to the connecting frame 12. The bottom sides of both ends of the transverse connecting truss 112 are connected to the top ends of the two longitudinal main trusses 111 respectively.
[0019] In this embodiment, specifically, two support frames 11 are arranged at intervals along the length of the riverbank, and two longitudinal main trusses 111 in each connecting frame 12 are arranged at intervals along the width of the riverbank; the two longitudinal main trusses 111 and the transverse connecting trusses 112 are specifically arranged in an inverted "U" shape.
[0020] Both longitudinal main trusses 111 are arranged perpendicular to the ground, with a height of 1500mm and a cross-sectional dimension of 1000mm in length and 600mm in width. The longitudinal main trusses 111 are made of several hot-rolled equilateral angle steels selected from GB / T9787-1988 and several square hollow steels selected from GB / 6728-1986. They mainly bear the normal pressure from the transverse connecting trusses 112 and the bending moment from the connection of the gantry frame body 1.
[0021] The transverse connecting trusses 112 are all perpendicular to the longitudinal main trusses 111 and parallel to the ground. The length of the transverse connecting truss 112 is 3600mm and its cross-sectional dimensions are 1000mm in width and 500mm in height. The transverse connecting trusses 112 are made of several hot-rolled equilateral angle steels selected from GB / T9787-1988 and several square hollow steel sections selected from GB / 6728-1986.
[0022] The connecting frame 12 is also perpendicular to the longitudinal main truss 111 and parallel to the ground. The length of the connecting frame 12 is 5600mm and its cross-sectional dimensions are 1200mm in width and 1000mm in height. The connecting frame 12 is made of several hot-rolled equilateral angle steels selected from GB / T9787-1988 and several square hollow steel sections selected from GB / 6728-1986.
[0023] Furthermore, the end of the connecting frame 12 is connected to the middle position of the side wall of the corresponding longitudinal main truss 111, ensuring that the two supporting frames 11 can be stably connected and that there is enough reserved space on the top side of the two supporting frames 11 for the moving crossbeam to be moved in.
[0024] For ease of movement, as shown in Figure 1, according to another embodiment of this utility model, the modular collaborative repair workstation for shore-based mobile concrete lining panels is provided with moving components at the bottom of the longitudinal main truss 111. The moving components drive the gantry frame body 1 to move, thereby driving the underwater part of the channel concrete lining panel underwater repair equipment to move together, facilitating rapid movement to the next repair area. The moving components are tracked walking mechanisms 14, which have good wear resistance and grip, and can travel on various complex terrains, such as mud, sand, and slopes.
[0025] The tracked walking mechanism 14 mainly consists of tracks, drive wheels, guide wheels, support wheels, tensioning devices, and a walking speed reducer. The tracks are made of high-strength rubber.
[0026] During travel, the tracks come into contact with the ground, creating a large ground contact area and reducing the ground pressure, enabling the tracked traveling mechanism 14 to travel stably on soft ground. At the same time, the grip of the tracks also ensures the good passability of the tracked traveling mechanism 14 on slopes.
[0027] The drive wheels are connected to the power source via a travel reducer, which drives the tracks to rotate, enabling the mechanism to move. Guide wheels and support wheels support the tracks and maintain their correct position, while the tensioning device adjusts the track tension to ensure that the tracks do not loosen or slip off during movement.
[0028] The drive system uses an electric motor as its power source, offering advantages such as accurate control and simple maintenance. The power source is connected to the travel reducer via a coupling, and the travel reducer employs a planetary gear reduction structure. The reducer converts the high-speed, low-torque output of the power source into low-speed, high-torque output to meet the needs of tracked movement.
[0029] The specific motion is as follows: the electric motor drives the drive wheel to rotate through the travel reducer, and the drive wheel drives the track to rotate around the guide wheel and the support wheel, thereby propelling the tracked travel mechanism 14 forward or backward. By controlling the speed and direction of the travel reducer, the tracked travel mechanism 14 can achieve stepless speed regulation and flexible steering.
[0030] As shown in Figure 1, according to another embodiment of the present invention, the modular collaborative repair workstation for shore-based mobile concrete lining slabs further includes a lifting and traction component installed on the connecting frame 12, the lifting and traction component including a winch 2.
[0031] Winch 2, as a commonly used lifting and traction device, achieves the lifting or movement of heavy objects by winding and releasing steel wire ropes. In the underwater repair equipment for channel concrete lining panels, winch 2 is mainly used to hold the moving crossbeam. It acts as a safety measure in case the power unit of the moving crossbeam malfunctions or stops, preventing the moving crossbeam from becoming displaced or out of control, and ensuring safety.
[0032] In this embodiment, there are two winches 2.
[0033] When winch 2 is working, the wire rope is taut, and concrete waste transport vehicles are not allowed to pass through the gantry frame body 1. When winch 2 is not working, the wire rope is slack and laid flat on the ground, at which time concrete waste transport vehicles are allowed to pass through the gantry frame body 1.
[0034] In this invention, "shore base" can refer to the deployment location and operating scope of equipment or devices that are limited to the shoreline area, such as on dikes, canals, or reservoir slopes.
[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
