Description

Technical Field

[0001] This utility model relates to the field of metal structure technology for water conservancy projects, and in particular to a locking mechanism for a trash rack tie rod. Background Technology

[0002] When the trash rack tie rods are installed inside the orifice, the tie rods are locked using two longitudinally spanning the orifice and supported by locking beams on the upstream and downstream maintenance platforms. However, if a trash rack cleaning machine is installed upstream of the trash rack, the locking beams will obstruct the machine's operation. Before cleaning, the tie rods must be connected to the trash rack hoist, and the hoist's braking device must be used to lock them. The locking beams must then be removed to allow the cleaning machine to enter the tank for cleaning. However, the hoist's wire rope will hinder the cleaning machine's downstream movement for unloading. The unloading platform must be located upstream of the trash rack, and manual transfer is required. The current method is inconvenient to operate, requires a large investment for an unloading platform upstream of the trash rack, and has high operating costs in the long run.

[0003] To address the shortcomings of existing methods, this invention provides a locking mechanism for the tie rod of a trash rack. A rear-mounted locking beam is arranged on the downstream side of the trash rack, and a locking seat is installed on the locking beam to lock the trash rack tie rod. This solves the problem of interference between the locking beam and the trash rack cleaning machine. In practical engineering applications, this mechanism has significant economic value in saving project investment and reducing subsequent operating costs. Utility Model Content

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0027] Example 1

[0028] Reference Figure 2 5. This is the first embodiment of the present utility model. This embodiment provides a trash rack tie rod locking mechanism, which includes a rear-clamping locking beam 100 and two sets of track assemblies 200 disposed at both ends of the rear-clamping locking beam 100, and the rear-clamping locking beam 100 is installed above the track assemblies 200; the rear-clamping locking beam 100 includes a main crossbeam 101, two sets of upstream side beams 102 and two sets of downstream side beams 103; the two sets of upstream side beams 102 are fixedly connected to one end of the main crossbeam 101, and the two sets of downstream side beams 103 are fixedly connected to the other end of the main crossbeam 101, and the upstream side beams 102 and downstream side beams 103 are asymmetrically arranged.

[0029] The rear-mounted locking beam 200 normally rests on the maintenance platform at the end of the track assembly 200 away from the trash rack rod, and the rear-mounted locking beam 200 locks the trash rack rod by sliding along the track assembly 200. When it is necessary to lock the trash rack rod, the hoist lifts the trash rack rod and pushes the rear-mounted locking beam 100, causing it to slide along the track 200 until it is close to the trash rack rod. Then, the hoist places the trash rack rod on the rear-mounted locking beam 100, thus locking the trash rack rod. When it is necessary to unlock the trash rack rod, the hoist lifts the trash rack rod and slides the rear-mounted locking beam 100 along the track 200 to the maintenance platform, away from the trash rack rod. Then, the trash rack rod is lowered to release the lock.

[0030] In summary, the beneficial effect of a trash rack tie rod locking mechanism is that the sliding of the rear-mounted locking beam on the track completes the release and locking of the trash rack tie rod, thus solving the problem of interference between the trash rack tie rod locking and the trash cleaning machine.

[0031] Example 2

[0032] Reference Figure 1 , 3 ~5 is the second embodiment of this utility model. Unlike the previous embodiment, this embodiment provides a trash rack tie rod locking mechanism, which includes two sets of square grooves M at the bottom of both ends of the main crossbeam 101; the two sets of square grooves M extend to the bottom of the upstream side beam 102 and the downstream side beam 103 respectively.

[0033] The main crossbeam 101 is a double-web box girder.

[0034] The rear-mounted locking beam 100 also includes four sets of locking seats 104; the locking seats 104 are fixedly connected to the side of the main crossbeam 101 near the bottom of the trash rack; and a stop block 104a is provided at the other end of the locking seat 104.

[0035] The rear-mounted locking beam 100 also includes four sets of traveling wheels 105; two sets of traveling wheels 105 are rollingly connected to the upstream side beam 102, and the other two sets of traveling wheels 105 are rollingly connected to the downstream side beam 103.

[0036] The traveling wheel 105 is also in a rolling connection with the track assembly 200.

[0037] Preferably, the load of the rear-mounted locking beam acts on the stepped locking seat, and the load transfer to the beam is eccentric. Under the action of eccentric load, it is necessary to prevent the rear-mounted locking beam 100 from overturning. Therefore, in this utility model, the rear-mounted locking beam 100 adopts an asymmetrical beam design, that is, the upstream side beam 102 and the downstream side beam 103 are asymmetrically arranged on both sides of the rear-mounted locking beam 100, which effectively ensures the stability of the beam.

[0038] Preferably, the double-web box girder is a type of beam used in bridge engineering. It is hollow internally with flanges on both the top and bottom sides, effectively resisting positive and negative bending moments. In large-span spaces, its closed thin-walled section exhibits high torsional stiffness, which is particularly advantageous for bridges constructed using cantilever construction. The main crossbeam 101 adopts a double-web box girder structure. When the trash rack tie rod is locked, the main crossbeam 101 has moved from the maintenance platform to above the trash rack. At this time, the main crossbeam 101 is positioned along the width of the trash rack opening. Therefore, the main crossbeam 101 of the double-web box girder structure can effectively bear the weight of the trash rack, tie rod, and debris, meeting both structural strength requirements and enhancing stability.

[0039] Preferably, traveling wheels 105 are respectively provided at the bottom of the upstream side beam 102 and the downstream side beam 103, and square grooves M are provided at the bottom of both sides of the main cross beam 101 for the traveling wheels 105 to contact and roll with the panel 202 of the track assembly 200. The movement of the rear-mounted locking beam is achieved by the traveling wheels 105, which not only has low rolling friction resistance but also facilitates operation.

[0040] Preferably, the locking seat 104 adopts a stepped locking seat. The locking seat 104 mainly bears the shear force. The stepped design not only meets the force requirements, but also effectively reduces the height of the trash rack tie rod extending out of the maintenance platform, which facilitates the disassembly and maintenance of the trash rack tie rod.

[0041] In use, when it is necessary to lock the trash rack tie rod, the hoist is used to lift the trash rack tie rod, and then the main crossbeam 101 is pushed, causing the traveling wheels 105 on both sides of the main crossbeam 101 to roll from the maintenance platform towards the end near the trash rack tie rod. This causes the upstream side beam 102 and downstream side beam 103, which are fixedly connected to the main crossbeam 101, to slide on the track assembly 200. The height of the trash rack tie rod locking plate exceeds the height of the locking seat 104. At this time, the locking seat 104, which is fixedly connected to the main crossbeam 101, is placed directly in front of the trash rack tie rod locking plate, so that the trash rack tie rod is locked in both sets of locking mechanisms. In the middle of seat 104, the trash rack rod is lowered so that the trash rack rod locking plate falls on the locking seat 104 of the main crossbeam 101. At this time, the stop block 104a at the front end of the locking seat 104 can prevent the trash rack rod lock from sliding, thus completing the locking. When it is necessary to lock the trash rack rod, the trash rack rod is lifted by the hoist, so that the trash rack rod locking plate is separated from the locking seat 104. The main crossbeam 101 is pushed so that the traveling wheels 105 on both sides of the main crossbeam 101 roll away from the end of the trash rack rod until it reaches the maintenance platform. At this time, the trash rack rod is lowered, thus releasing the lock.

[0042] In summary, the beneficial effect of this trash rack tie rod locking mechanism is that the movement of the rear-mounted locking beam is achieved by the rolling of the traveling wheels at both ends of the main crossbeam. Then, the locking and unlocking of the trash rack tie rod is completed through the cooperation of the stepped locking seat on the rear-mounted locking beam and the trash rack opening and closing machine. This not only solves the problem of interference between the locking beam and the trash rack cleaning machine, but also saves manpower and facilitates operation and maintenance.

[0043] Example 3

[0044] Reference Figure 2 5. This is the third embodiment of the present utility model. Unlike the previous embodiment, this embodiment provides a trash rack pull rod locking mechanism, which includes a track assembly 200 including two sets of rail heads 201 disposed at the bottom of the upstream side beam 102 and the downstream side beam 103, a panel 202 fixedly connected to the bottom of the rail head 201, and a limiting block 203 fixedly connected to both ends of the rail head 201.

[0045] The track assembly 200 also includes four sets of supporting steel sections 204 fixedly connected to the bottom of the panel 202, and anchoring steel bars 205 fixedly connected to the bottom of the supporting steel sections 204.

[0046] The track assembly 200 is fixed to the maintenance platform by anchoring steel bars 205 fixedly connected to the bottom.

[0047] The bottom of the main crossbeam 101 is higher than the top of the panel 202.

[0048] It should be noted that both sets of track assemblies 200 are installed on the maintenance platform. One end is on both sides of the slot opening of the trash rack, that is, on both sides of the trash rack tie rod, and the other end is on the side away from the slot opening of the trash rack. That is, the two sets of track heads 201 are installed, one set close to the trash rack tie rod and the other set away from the trash rack tie rod.

[0049] Preferably, in concrete structures, the anchoring steel bars 205 can bear the load, which not only improves the concrete bond strength at beam-column intersections but also saves a lot of steel reinforcement. Four sets of anchoring steel bars 205 are provided at the bottom of this track assembly 200 to further enhance its stability.

[0050] In summary, the beneficial effect of a trash rack tie rod locking mechanism is that by anchoring the steel bars at the bottom of the track, the track can be firmly attached to both sides of the trash rack groove, providing a basis for the rolling of the rear-mounted locking beam on the track, and enabling the rear-mounted locking beam to better lock and release the trash rack tie rod.
