Description

Technical Field

[0001] This utility model relates to the technical field of locking beam auxiliary devices, and in particular to a locking beam moving device for a hydropower station gate. Background Technology

[0002] In the current hydropower station operation system, the gate, as the core component for regulating water flow, relies heavily on the coordinated work of the locking beam for stable positioning. The locking beam is essentially a key mechanical locking device. After the gate completes the opening or closing action, it is rigidly fixed by embedding itself in a predetermined position, thereby effectively resisting the impact of water pressure and vibration, and preventing the gate from drifting or sliding down unexpectedly. Due to the characteristics of its structure and materials, the gate of a hydropower station is often large in weight and volume. The use of the locking beam usually requires moving it into the gate slot, which is a relatively narrow space, making the use and movement of the locking beam complex and difficult.

[0003] In the current operation of hydropower station gates, the locking beam is usually put into or taken out of use by manually lifting it with a pry bar. This traditional manual operation method has obvious limitations, mainly in that: the locking beam is inefficient to move, requiring multiple operators to spend a lot of time and energy to position, move and fix the heavy beam. In addition, due to the limited space of the gate slot and the complexity of the operating environment, manual movement of the locking beam is also accompanied by high safety hazards, which can easily lead to operational errors or accidents, threatening the personal safety of the operators. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a hydropower station gate locking beam moving device, which solves the problems of low moving efficiency of locking beams, high labor costs, and safety risks in existing technologies.

[0005] According to an embodiment of this utility model, a moving device for a locking beam of a hydropower station gate includes a bearing plate fixedly disposed on both sides of the locking beam. A rolling mechanism is fixedly disposed on the outer side of the bearing plate. The rolling mechanism includes a pair of slide rails parallel to both sides of the gate slot and a roller frame with rollers rotatably disposed at the bottom. The rollers have annular grooves around their arc surfaces for the slide rails to engage with. The top of the roller frame is elastically connected to the bearing plate. Locking members that can abut against the rollers are slidably disposed at both ends of the slide rails. The locking members can self-lock at any position of the slide rails.

[0006] The technical principle of this utility model is as follows: When it is necessary to move the locking beam, the operator can directly push the device on the slide rail to the predetermined position, and make it tightly abut against the roller and self-lock by sliding the locking parts set at both ends of the slide rail, thereby firmly locking the roller and realizing accurate positioning and reliable locking of the locking beam; when the gate is engaged, as the gate falls, the bearing plate is elastically compressed and finally contacts the ground, realizing the gate locking.

[0007] Furthermore, a protective box is fixedly connected to the outside of the bearing plate, and at least one sliding groove is longitudinally provided inside the protective box. An equal number of sliding columns that can be inserted into the sliding groove are fixedly provided on the top of the roller frame. A limit seat is detachably provided on the top of the sliding groove, and the sliding column and the limit seat are connected by a return spring.

[0008] Furthermore, the limiting seat has a through hole in the middle, and a limiting rod that can pass through the through hole is coaxially fixed on the top of the limiting seat, with a cotter pin on the top of the limiting rod.

[0009] Furthermore, a limiting plate is fixedly installed at the bottom of the protective box, and a clearance groove is provided on the roller frame for the limiting plate to pass through.

[0010] Furthermore, the locking component includes a locking block, the bottom of which is provided with a groove for the slide rail to pass through, and the top and sidewalls of the locking block are respectively threaded with a first rotating rod and a second rotating rod, which can be screwed in and abut against the slide rail.

[0011] Furthermore, the locking block has an abutment surface on the side near the roller frame that can fit against it.

[0012] Furthermore, the bottom of the roller frame is provided with a slot, and a mounting position for rotating connection with the roller is provided in the slot for mounting the roller.

[0013] Furthermore, the number of mounting positions is at least two.

[0014] Furthermore, a drive mechanism is fixedly installed on the side away from the gate slot. The output end of the drive mechanism is hinged to the connecting lug fixed on the locking beam. The drive mechanism includes a linear motor, a pneumatic cylinder, or a hydraulic cylinder.

[0015] Furthermore, the connecting ear is provided with a longitudinal groove, the shape of which includes waist-shaped or strip-shaped.

[0016] Compared with existing technologies, this utility model has the following advantages: The sliding rail and rollers work together to allow the locking beam to move easily, accurately, and smoothly under the guidance of the sliding rail, significantly reducing the physical exertion and time required by operators and improving work efficiency. The self-locking locking element, which can slide on the sliding rail, allows the operator to quickly press the locking element against the rollers to achieve stable mechanical locking once the locking beam reaches the target position, effectively preventing accidental displacement of the locking beam during gate operation and improving the reliability of the equipment's fixation. Simultaneously, the elastic connection between the bearing plate and the top of the roller frame ensures that the bearing plate stably contacts the ground to support the weight of the gate when it falls, protecting the rollers and ensuring the stability of the gate locking.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0023] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0024] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0025] like Figure 1-3 As shown in the figure, this utility model embodiment proposes a moving device for a locking beam 1 of a hydropower station gate, which includes a bearing plate 2 fixedly installed on both sides of the locking beam 1. A rolling mechanism is fixedly installed on the outer side of the bearing plate 2. The rolling mechanism includes a pair of slide rails 3 parallel to both sides of the gate slot and a roller frame 4 with a roller 41 rotatably installed at the bottom. The roller 41 has an annular groove 411 around its arc surface for the slide rail 3 to be inserted into. The top of the roller frame 4 is elastically connected to the bearing plate 2. Locking members that can abut against the roller 41 are slidably installed at both ends of the slide rail 3. The locking members can self-lock at any position of the slide rail 3.

[0026] In an exemplary embodiment, the bearing plate 2 is preferably made of I-beam. I-beams have the advantages of being lightweight and having a high load-bearing capacity for the same volume. Their wide upper and lower flanges provide a larger load-bearing and contact area for the locking beam 1 and the foundation, thereby forming a stable I-shaped support structure and effectively ensuring the overall stability of the gate during locking. The bearing plate 2 and the locking beam 1 are fixed by welding or bolts, and the two together form a rigid I-shaped support frame, thus providing a stable and reliable load-bearing foundation for the gate to fall. The rollers 41 in the rolling mechanism are circumferentially open. The annular groove 411 precisely engages with the flange of the slide rail 3, forming an effective radial constraint, ensuring that the device always stays on the predetermined trajectory when moving along the slide rail 3. At the same time, anti-derailment blocks 31 can be fixedly installed at both ends of the slide rail 3 to eliminate the risk of the roller 41 running off track or derailing. More importantly, the locking members slidably installed at both ends of the slide rail 3 can be easily pushed to a position close to the side of the roller 41 and firmly fixed by utilizing the self-locking characteristic, so that the locking beam 1 can be quickly and reliably locked at any desired position on the slide rail 3, completely eliminating the safety hazards that may be caused by accidental movement.

[0027] Based on the above configuration, this embodiment utilizes the rolling cooperation between the slide rail 3 and the roller 41 to allow the locking beam 1 to move easily, accurately, and smoothly under the guidance of the slide rail 3, significantly reducing the physical exertion and time consumption of the operator and improving work efficiency. Through the locking element that can slide and self-lock on the slide rail 3, the operator can quickly press the locking element against the roller 41 to achieve stable mechanical locking after the locking beam 1 reaches the target position, effectively preventing accidental displacement of the locking beam 1 during gate operation and improving the reliability of the equipment's fixation. Simultaneously, the elastic connection between the bearing plate 2 and the top of the roller frame 4 ensures that when the gate falls, the bearing plate 2 can stably contact the ground to bear the weight of the gate, protecting the roller 41 and ensuring the stability of the gate locking.

[0028] In this embodiment, the operator can directly push the device on the slide rail 3 to the predetermined position, and make it tightly abut against the roller 41 and self-lock by sliding the locking parts set at both ends of the slide rail 3, thereby firmly locking the roller 41 and realizing accurate positioning and reliable locking of the locking beam 1; when the gate is engaged, as the gate falls, the bearing plate 2 is elastically compressed and finally contacts the ground, realizing the gate locking.

[0029] like Figure 1-3 As shown, in another embodiment, a protective box 5 is fixedly connected to the outside of the bearing plate 2. At least one sliding groove 51 is longitudinally arranged inside the protective box 5. An equal number of sliding columns 42, capable of sliding into the sliding grooves 51, are fixedly arranged on the top of the roller frame 4. Preferably, there are two sliding grooves 51 and two sliding columns 42, symmetrically arranged with respect to the locking beam 1. A limiting seat 53 is detachably provided on the top of the sliding groove 51 by bolts. The sliding column 42 is connected to the limiting seat 53 by a return spring 52. In this embodiment, the return spring 52 is a compression spring, and its pitch, number of turns, and elastic force can be flexibly set according to actual conditions, without limitation. However, it should be noted that in the non-load-bearing state, the bearing plate 2 is at a distance from... The distance from the ground should be less than the compressible deformation distance of the return spring 52 to prevent overpressure damage to the return spring 52. Based on the above settings, the symmetrical sliding layout of the double sliding columns 42 effectively constrains the vertical movement trajectory of the protection box 5, ensuring the stability and centering of the lifting process of the bearing components, and effectively avoiding jamming caused by off-center loading. The limit seat 53 provides upper support for the return spring 52, so that the return spring 52 can reliably lift the bearing structure composed of the locking beam 1, the bearing plate 2 and the protection box 5 off the ground, thereby ensuring that the device moves flexibly and without obstruction. When the gate falls, the spring compression can effectively buffer and absorb the impact energy, realizing the smooth contact between the bearing plate 2 and the foundation and the load transfer.

[0030] like Figure 1-3As shown, in this embodiment, the limiting seat 53 is further provided with a through hole 531 in the middle, and a limiting rod 43 that can pass through the through hole 531 is coaxially fixedly provided on the top of the limiting seat 53. The through hole 531 and the limiting rod 43 are clearance-fitted, and a cotter pin 431 is provided on the top of the limiting rod 43. Based on the above configuration, the limiting rod 43 can pass through the center of the return spring 52, providing radial constraint for it during the compression and rebound of the spring, thereby significantly enhancing its motion stability and effectively preventing the spring from bending or jamming. The cooperation between the limiting rod 43 and the through hole 531 also improves the centering of the sliding column 42 during its up and down movement and enhances its anti-displacement capability. The cotter pin 431 at the top constitutes a reliable mechanical stop, preventing the limiting rod 43 from accidentally retracting into the sliding groove 51 due to the excessively rapid or excessive release of the elastic pressure accumulated in the return spring 52 during the release of the load, which would cause the protective box 5 to detach from the sliding column 42 and fall off, thus ensuring the safety of the connection between key load-bearing components.

[0031] like Figure 1-3 As shown, in this embodiment, a limiting plate 54 is further fixedly provided at the bottom of the protective box 5. The limiting plate 54 is preferably configured as a trapezoidal structure. The protective box 5 and the limiting plate 54 are fixed by welding or integral fabrication. The roller frame 4 is provided with a clearance groove 44 for the limiting plate 54 to pass through. Based on the above configuration, when the return spring 52 is compressed, the limiting plate 54 can act as a rigid stop and contact the foundation, sharing the final load of the gate with the bearing plate 2, so as to prevent the return spring 52 from being damaged due to excessive compression and ensure the absolute reliability of the support. At the same time, the cooperation between the side wall of the clearance groove 44 and the limiting plate 54 constitutes a horizontal limiting mechanism, which together restricts the potential swing of the roller frame 4 in the horizontal plane and enhances the structural rigidity and stability of the entire device in the working and moving states.

[0032] like Figure 1-3 As shown, in another embodiment, the locking component includes a locking block 6. The bottom of the locking block 6 is provided with a groove for the slide rail 3 to pass through. The top and side walls of the locking block 6 are respectively threaded with a first rotating rod 61 and a second rotating rod 62. The first rotating rod 61 and the second rotating rod 62 can be screwed in and pressed against the slide rail 3. Based on the above configuration, by tightening the first rotating rod 61 at the top of the locking block 6, its lower end can be firmly pressed against the upper surface of the slide rail 3, realizing the rapid initial fixation of the locking block 6 on the track. Then, by tightening the second rotating rod 62 on the side wall, its end is tightly pressed against the side of the roller 41, thereby completing the further locking of the locking block 6. The sliding and locking process is quick and convenient, and the locking position can be flexibly adjusted according to the position of the roller 41, which greatly enhances the anti-movement ability and overall stability of the locking beam 1 after it is in place.

[0033] like Figure 1-3As shown, in this embodiment, the locking block 6 is further provided with a planar abutment surface 63 that can fit against the roller frame 4 on the side near the roller frame 4. The abutment surface 63 can increase the contact area with the side wall of the roller frame 4 by fitting, which further enhances the anti-slip locking effect of the device compared with point or line contact.

[0034] like Figure 1-3 As shown, in another embodiment, the roller frame 4 is preferably configured as a long box-shaped structure. The bottom of the roller frame 4 is provided with a slot 412, and a mounting position 413 rotatably connected to the roller 41 is provided in the slot 412 for mounting the roller 41. The mounting positions 413 are horizontally arranged in the slot 412, and there are at least two mounting positions 413 arranged parallel to the locking beam 1. Based on the above configuration, the long box-shaped roller frame 4 has high bending and torsional rigidity, which can effectively resist the deformation generated under load. The multiple horizontally rotatable rollers 41 effectively disperse the load borne by a single roller 41, significantly reduce local contact stress, extend service life, increase the stability and anti-eccentric load capacity of the roller 41 during movement, and ensure that the locking beam 1 always maintains straight movement without deviation or jamming.

[0035] like Figure 1-4 As shown, in another embodiment, a drive mechanism 7 is fixedly installed on the side away from the gate slot. The output end of the drive mechanism 7 is hinged to the connecting lug 11 fixed on the locking beam 1. The drive mechanism 7 includes, but is not limited to, a linear motor, a pneumatic cylinder, or a hydraulic cylinder, etc., which can drive the locking beam 1 to move linearly. The specific configuration is flexible according to the actual situation and is not limited here. Based on the above configuration, the drive mechanism 7 can provide stable and reliable power for the movement of the locking beam 1 on the slide rail 3, ensuring that it can accurately and smoothly reach and fix in the target position under different working conditions. The operator can realize the automatic movement of the locking beam 1 by remotely controlling the drive mechanism 7, which significantly improves the work efficiency and work safety. Furthermore, the connecting lug 11 is provided with a longitudinal groove 111, which is preferably waist-shaped or elongated. The longitudinal groove 111 can provide the necessary vertical movement margin for the output end of the drive mechanism 7 hinged to it when the locking beam 1 is vertically displaced, avoiding rigid interference between the drive mechanism 7 and the locking beam 1, preventing equipment deformation or damage due to over-constraint, and ensuring the safety and durability of the drive mechanism 7 in long-term use.

[0036] 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.
