Description

Technical Field

[0001] This utility model relates to the field of dam construction technology, and in particular to a self-propelled traction and lifting operation platform. Background Technology

[0002] As one of the main dam types in water conservancy projects, concrete-faced rockfill dams are prone to typical defects such as cracks, damage to the joint sealing system, and settlement deformation due to the long-term effects of water storage and settlement on their upstream anti-seepage panels. The upstream anti-seepage panels are the main structure to ensure the safe operation of the dam, and anti-seepage of the panels is also a key item in the maintenance of hydraulic structures.

[0003] However, the dam height of large-scale water conservancy projects generally exceeds 100 meters, and the slope ratio of the dam face reaches 1:1.4 to 1:1.7 (approximately 35° to 30°), making it difficult for workers to stand and for construction measures to be set up. The construction of the dam face for seepage prevention and maintenance involves risks such as working near water, near edges, and at heights.

[0004] To address the aforementioned challenges, the current industry-standard solutions mainly include two types: 1) Steel pipes are used to erect large-angle sloping scaffolding, and bottom limiting rebar installation is used to achieve anti-slip effect; 2) Mobile operation platform system, which relies on the panel to set up anchor points to pull the mobile operation platform.

[0005] While erecting scaffolding on steep inclines can meet construction requirements, it has the following drawbacks: 1) The slope angle of the water-facing panel is large, making scaffolding erection and dismantling difficult; 2) Scaffolding with large angles and slopes requires special inspection, which is complex and has high maintenance costs; 3) Bottom-limiting rebar installation will damage the original structure of the panel and affect the panel's waterproof function.

[0006] Using anchor points to pull a mobile work platform is more convenient than building scaffolding on steep slopes, but it has the following drawbacks: 1) The slope angle of the water-facing panel is large, making it difficult to arrange anchor points, and the panels cannot be reused after installation; 2) After the anchor points are set up, the coverage area of ​​the mobile operation platform is limited, and it cannot move across the panel joint waterstop. 3) Setting up anchor points will damage the original structure of the panel and affect the panel's waterproof function.

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0032] Reference Figure 1-10 A self-propelled traction and lifting operation platform includes a support frame 1 and a suspension frame 2 connected to the inner side of the top of the support frame 1; the inner space of the suspension frame 2 is matched with the thickness of the wave-breaking wall 6.

[0033] The support frame 1 is triangular, with rollers 3 at its inner end that contact the wave-breaking wall 6; the suspension frame 2 is a right-angled "7" shape, hooked onto the top and downstream sides of the wave-breaking wall 6; rollers 3 are also installed on its inner side that contact the wave-breaking wall 6; the support frame 1, suspension frame 2, and rollers 3 work together to achieve movement.

[0034] It should be noted that during operation, the overall center of gravity is located below the upstream side of the support frame 1 to maintain reliable stability; the two-sided contact structure of the suspension frame 2 cooperates with the one-sided contact structure of the support frame 1, making the whole system stable, balanced and reliable.

[0035] Meanwhile, a vertical lifting structure 4 is set at the top of the support frame 1, and a parallel traction structure 5 is set at the bottom to achieve traction operations in different directions; at the same time, the two work together to achieve operations such as suspending and moving the traction object.

[0036] Understandably, it also includes: a control box 23 fixed to the outside of the suspension frame 2.

[0037] The control box 23 is connected to an external power source and controls each component; it can control the overall movement of the operating platform, as well as the operation of the vertical lifting structure 4 and the parallel traction structure 5, etc.

[0038] like Figure 1 As shown; preferably, the control box 23 is installed on the downstream side of the suspension frame 2; alternatively, the control box 23 can also be installed on the upper part of the support frame 1 or the suspension frame 2.

[0039] It should be noted that at least one roller 3 is powered; that is, at least one roller 3 is connected to the drive motor or other form of power; the control box 23 controls the drive motor and outputs power through the roller 3 to achieve the overall movement.

[0040] Among them, the roller 3 can be made of natural rubber, polyurethane, ultra-high molecular weight polyethylene, etc.; it is preferred to use a material with good wear resistance; any suitable form can be used for the transmission connection, which will not be elaborated here.

[0041] Optionally, solar panels are installed above the support frame 1 and the suspension frame 2, along with a battery pack, to achieve a certain degree of energy self-sufficiency. It is understood that the solar panels are not essential, but rather an optional auxiliary component.

[0042] Preferably, the support frame 1 and the suspension frame 2 are made of I-beams, channel steel, H-beams, etc., and are assembled as a whole through welding, bolting, or other means.

[0043] In some embodiments, the support frame 1 includes: a crossbeam 11, a vertical beam 12, a diagonal brace 13, and a connecting rod 14.

[0044] The triangular frame is composed of horizontal beam 11, vertical beam 12, and diagonal brace 13; the two triangular frames are connected by multiple connecting rods 14 to form a three-dimensional structure.

[0045] Specifically, the top of the diagonal brace 13 is connected to the lower end of the crossbeam 11, and the bottom of the diagonal brace 13 is connected to the upstream side of the vertical beam 12; the top of the vertical beam 12 is connected to the lower end of the crossbeam 11.

[0046] Optionally, the crossbeam 11 extends upstream into a cantilever section.

[0047] like Figure 2 As shown, the triangular support frame 1 forms a better stress distribution shape.

[0048] Furthermore, a reinforcing rod is provided on the inner side of the support frame 1 to enhance structural stability.

[0049] like Figure 8 As shown, the reinforcing bar consists of several horizontal and diagonal bars, which are connected by welding or bolts.

[0050] In some embodiments, the suspension frame 2 includes a horizontal beam 21 and a vertical beam 22 at the lower end of the horizontal beam 21.

[0051] It should be noted that the internal space of the suspension frame 2 is designed according to the thickness of the wave-breaking wall 6; the length of the vertical beam 12 supporting the frame 1 is designed according to the height of the wave-breaking wall 6.

[0052] Due to the varying thicknesses of wave walls in different dams, the fixed support frame 1 and suspension frame 2 have limited applicability. Therefore, further improvements have been made to the coordination between the two, allowing for adjustment of the internal space of the suspension frame 2.

[0053] In some embodiments, the crossbeam 11 and the horizontal beam 21 are detachably connected by connecting plates at opposite ends; the horizontal beam 21 is matched with different lengths according to the different thicknesses of the wave-breaking wall 6.

[0054] like Figure 6 , 7 As shown, a relatively universal support frame 1 is designed; and a suspension frame 2 with different horizontal beams 21 lengths is used to accommodate different wave-breaking wall 6 thicknesses.

[0055] In some embodiments, an extension section can be provided between the crossbeam 11 and the horizontal beam 21; by adding extension sections of different lengths, the internal space of the suspension frame 2 can be adjusted.

[0056] Preferably, the extended section adopts a structure that cooperates with the crossbeam 11 and the horizontal beam 21 (such as I-beam, square steel, etc.); connecting plates are fixed at both ends and connected to the crossbeam 11 and the horizontal beam 21 by bolts.

[0057] Furthermore, long screws running through both ends of the extended section are used for assembly, which further improves the strength and load-bearing capacity of the connection point.

[0058] In some embodiments, the crossbeam 11 and the horizontal beam 21 are an integral structure; the crossbeam 11 extends rearward to form the horizontal beam 21 of the suspension frame 2.

[0059] At this point, by adjusting the installation position of the crossbeam 11, the internal space of the suspension frame 2 can be adjusted to accommodate different wave-breaking wall thicknesses.

[0060] Specifically, such as Figure 8 , 10 As shown; the top of the vertical beam 12 and the diagonal brace 13 are fixedly provided with perforated connecting plates 15; the horizontal beam 11 is detachably connected to the perforated connecting plates by bolts.

[0061] The crossbeam 11 has multiple openings; the rearward extension length of the crossbeam 11 is adjusted according to the different thicknesses of the wave-breaking wall 6, and the corresponding assembly bolts are used.

[0062] It is important to note that bearing-type high-strength bolts should be used to ensure strength and load-bearing capacity; for example, 8.8 grade M20 bearing-type high-strength bolts should be used.

[0063] Preferably, the openings on the crossbeam 11 and the openings on the opening connecting plate 15 are elongated holes; this makes adjustment easier.

[0064] In some embodiments, the vertical beam 22 is detachably connected to the horizontal beam 21; by adjusting the installation position of the vertical beam 22, the internal space of the suspension frame 2 can be adjusted to accommodate different wave-breaking wall thicknesses.

[0065] Specifically, with Figure 10 Similarly, at this time, the crossbeam 11 is no longer adjusted; the perforated connecting plate 15 is fixedly connected to the top of the vertical beam 22, and multiple openings are set on the horizontal beam 21; the assembly position of the vertical beam 22 is adjusted according to the different thicknesses of the wave-breaking wall 6, and the corresponding assembly bolts are installed.

[0066] In some embodiments, the vertical lifting structure 4 includes: a lifting machine (not shown) fixed on the support frame 1, a guide pulley group 41 assembled at the front end of the support frame 1, a steel wire rope passing through the guide pulley group 41, and a traction hook connected to the end of the steel wire rope.

[0067] like Figure 1 As shown, a hoist is installed at the top to provide power; a guide pulley block 41 restricts the position of the wire rope; the hoist pulls the wire rope to perform the lifting operation.

[0068] The hoist should have suitable power, and the wire rope should have suitable load-bearing capacity.

[0069] Preferably, the vertical lifting structure 4 includes two LTD630 type hoists, two fixed pulley blocks, two sections of 6×19S+FC galvanized steel wire rope of appropriate length, and two lifting hooks. The LTD630 type hoists are symmetrically arranged on the left and right sides of the support frame 1, and fixed pulley blocks are installed at the ends of the crossbeams 11. After the lifting hooks are safely connected to the structure to be traction (e.g., a panel work platform), the controlled hoists can move the panel work platform by winding and unwinding the steel wire ropes.

[0070] In some embodiments, the parallel traction structure 5 includes: a hoist, a guide ring 51 or pulley block mounted on the lower end of the support frame 1, and a wire rope passing through the guide ring 51 or pulley block.

[0071] The hoist can reuse the hoist of the vertical lifting structure 4, or a separate hoist can be set up. Depending on the actual needs, if the vertical lifting structure 4 and the parallel traction structure 5 do not need to work at the same time, they can choose to share the hoist. If they need to work at the same time, a separate hoist needs to be set up. In this case, the hoist is preferably set on the diagonal brace 13 of the support frame 1.

[0072] In the preferred configuration of this application, the vertical lifting structure 4 and the parallel traction structure 5 need to work together; therefore, two independent sets of lifting machines are required.

[0073] In some embodiments, extension rods 8 are provided on both sides of the lower end of the support frame 1; multiple guide rings 51 or pulley blocks are provided at the front end (upstream side) of the extension rods 8 to adjust the traction distance on both sides.

[0074] like Figure 2 , 4 As shown; forming outwardly expanding limiting sites.

[0075] Please refer to Figure 1 The parallel traction structure 5 drives the panel working platform to move up and down along the dam surface. When it is necessary to move left and right, the panel working platform is first pulled to the position below the support frame 1. Then, the panel working platform is lifted up by the vertical lifting structure 4, detached from the dam panel 7, and suspended in the air. After that, the operating platform moves left and right by the rollers 3. After reaching the next working position, the panel working platform is lowered back to the dam surface.

[0076] It should be noted that when encountering locations such as the water-stop structure of the dam panel that affect movement, it may be necessary to lift the panel working platform to avoid that area.

[0077] In specific tasks: After connecting the panel working platform to the traction hook of the parallel traction structure 5, the control box 23 can control the parallel traction structure 5 to pull the panel working platform along the slope direction; adjust the traction speed and single movement distance according to the working conditions. After completing the work on the upper and lower slopes, the panel working platform is lifted to the bottom of the support frame 1 by the parallel traction structure 5; after connecting the panel working platform to the lifting hook of the vertical lifting structure 4, the vertical lifting structure 4 can be controlled by the control box 23 to lift the panel working platform to a suitable height away from the dam panel 7. Then, the operating platform moves left and right by controlling the motor drive roller 3 through the control box 23; after moving to a suitable position on the wave wall 6, the panel operating platform is lowered; after the panel operating platform falls to the dam panel 7, the traction hook of the parallel traction structure 5 is connected to it; and the operation at the next position is carried out.

[0078] This utility model has at least the following advantages: 1. Equipped with a walking mechanism, it can move on the wave wall to meet the deployment of the traction panel working platform on different sections of the dam panel; 2. Equipped with a vertical lifting device, it can realize the lifting and lowering movement of the panel operation platform, so as to change the working area of ​​the panel operation platform and through the panel joint water-stop structure; 3. Equipped with a parallel lifting device, the panel working platform can be pulled along the slope direction; 4. The platform enables the panel working platform to move on steep slopes and transfer between panels through traction and lifting. This self-propelled traction and lifting operating platform has advantages such as convenient construction, high safety, and strong practicality, which can effectively save construction time; it can be reused, significantly reducing construction costs; and it can enable the panel working platform to move on steep slopes and transfer between panels without damaging the original structure of the panel.
