[0002] Usually, the maintenance of the dam's spillway requires the use of an inspection platform. Workers inspect both sides of the dam's spillway on the inspection platform. Since the dam's maintenance process needs to start from the bottom of the dam from bottom to top, the dam's inspection platform needs to be hoisted to a designated position on the dam's spillway first. If ordinary hoisting methods are used, anchor points need to be installed on the dam's top, and then hoisting needs to be done with a traction rope. This method is not only time-consuming and labor-intensive, but will also cause certain damage to the dam's top, posing certain safety hazards. Utility Model Content
[0003] The utility model provides an anchoring hanging beam structure for a dam maintenance platform, which aims to avoid damaging the original structure of the dam when hoisting the maintenance platform and is safer and more reliable.
[0004] The utility model is realized through the following technical scheme: an anchoring hanging beam structure for a dam maintenance platform, gates are opened on the two side walls between the dam top and the top of the flood discharge channel slope of the dam, the anchoring hanging beam structure includes an anchoring hanging beam body, the two ends of the anchoring hanging beam body can be respectively located in the two gates and move vertically along the gates, and one side of the anchoring hanging beam body is connected to a fixing piece for fixing a traction rope.
[0005] Compared with the prior art, the utility model has the following advantages and beneficial effects:
[0006] In this solution, a gateway is opened and an anchoring beam body is provided so that both ends of the anchoring beam body are located in the gateway and can move vertically along the gateway. In this way, in actual application, the anchoring beam body is connected to the winch on the maintenance platform through a traction rope, and then the two are hoisted down along the gateway of the dam through the existing gantry crane on site. When the anchoring beam body reaches the top of the slope of the flood discharge channel, the maintenance platform can be towed to the designated position by the traction force of the winch on the maintenance platform.
[0007] The coordination of the anchoring beam structure and the gate in this solution can limit the left and right shaking of the anchoring beam body and the maintenance platform, thereby ensuring the stability of the anchoring beam body and the maintenance platform when they are hoisted in the flood discharge channel of the dam. This method solves the problem of the need to install anchor points on the top of the dam during ordinary hoisting, ensures the integrity of the dam structure, and contributes to safe operation. That is, this solution does not require the installation of anchor points on the top of the dam, and the operation is convenient, time-saving and labor-saving, and will not cause damage to the top of the dam, thereby avoiding safety hazards.
[0008] The setting of the fixing parts in this solution ensures stability while providing effective installation conditions for the subsequent installation of the traction rope.
[0009] Furthermore, the fixing member includes a mounting plate, a connecting tube and a connecting head, the mounting plate is fixedly connected to one side of the anchoring beam body, the connecting tube is located on one side of the mounting plate and is fixedly connected to the mounting plate, the connecting head is connected to the connecting tube, and one end of the traction rope is connected to the connecting head.
[0010] Beneficial effect: The fixing part in this scheme is used to connect the traction rope, so as to achieve the purpose of connecting the maintenance platform. The fixing part in this scheme is connected to the anchor hanging beam body through the mounting plate, and the connecting tube is connected to the mounting plate at the same time, which facilitates the connection between the connecting head and the connecting tube.
[0011] Furthermore, the connecting head is threadedly connected to the connecting tube.
[0012] Beneficial effect: In this solution, the connecting head is threadedly connected to the connecting tube, so that the connecting head can be quickly connected and disassembled with the connecting tube, and the traction rope is connected to the connecting head. When the maintenance platform is moved to the specified position, the traction rope can be quickly separated from the entire anchoring beam body by separating the connecting head from the connecting tube, thereby quickly realizing the separation of the maintenance platform and the anchoring beam body, and the operation is simpler and faster.
[0013] Furthermore, there are two fixing members, which are symmetrically arranged.
[0014] Beneficial effect: With such arrangement, the connection of the maintenance platform is more uniform, which can make the maintenance platform more stable and safer during hoisting.
[0015] Furthermore, a hanging seat is connected to the top of the anchoring hanging beam body, and a hanging hole is opened on the hanging seat.
[0016] Beneficial effect: The setting of the hanging seat and the hanging hole makes it more convenient for the lifting equipment to lift the anchor hanging beam body, and the operation is more convenient.
[0017] Furthermore, two of the hanging seats are provided, and the two hanging seats are symmetrically arranged with respect to each other.
[0018] Beneficial effect: Two symmetrically arranged suspension seats can ensure balance during lifting, thereby ensuring the stability of the entire lifting process.
[0019] Furthermore, two sets of guide wheel assemblies are provided on the anchoring beam body, and the two sets of guide wheel assemblies each include a guide wheel and a fixed seat, the fixed seat is connected to the anchoring beam body, and the guide wheel is rotatably connected to the fixed seat, and the guide wheels of the two sets of guide wheel assemblies can roll vertically along the two gate side walls respectively.
[0020] Beneficial effect: The two sets of guide wheel assemblies in this solution facilitate the movement of the anchoring beam body in the gate and reduce the resistance to movement.
[0021] Furthermore, the number of guide wheel assemblies in each group is two, and the two guide wheel assemblies are respectively located at the upper part and the lower part of the anchoring beam body.
[0022] Beneficial effect: Such a setting can improve the stability of the movement of the entire anchoring beam body, and further reduce the resistance to movement, so that the anchoring beam body moves more smoothly in the gate.
[0023] Furthermore, the two groups of guide wheel assemblies are located on the same side as the fixing member.
[0024] Beneficial effect: Since the anchoring beam body needs to be connected to the maintenance platform through a traction rope, the guide wheel assembly is installed on the same side of the fixing part in the scheme, so that the guide wheel assembly faces the side of the maintenance platform. Since the maintenance platform has a certain weight, it will generate pulling force on the anchoring beam body. The guide wheel assembly in this scheme can be offset against the side wall of the gate and play a supporting role, which can provide a pulling force for the maintenance platform, making the movement of the maintenance platform more stable and safe.
[0025] Furthermore, a guide rail is provided vertically on the inner side of the gate, and the guide wheel rolls vertically along the guide rail.
[0026] Beneficial effect: The setting of the guide rail can cooperate with the guide wheel to guide the movement of the guide wheel, thereby improving the stability of the movement of the anchoring beam body. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below in conjunction with embodiments and drawings. The schematic implementation manner of the utility model and its description are only used to explain the utility model and are not intended to limit the utility model.
[0036] like Figure 1 and Figure 5 As shown, this embodiment provides an anchoring hanging beam structure for a dam maintenance platform 3, and gates 101 are provided on the two side walls between the dam crest and the top of the spillway 1 of the dam. Figure 1 As shown, the anchoring beam structure includes an anchoring beam body 2. In this embodiment, the anchoring beam body 2 is a rectangular parallelepiped structure as a whole, and adopts a triangular frame structure, which is light and can ensure that the anchoring beam body 2 has sufficient strength and stability.
[0037] In this embodiment, the two ends of the anchoring beam body 2 can be respectively located in the two gates 101 and move vertically along the gates 101. One side of the anchoring beam body 2 is connected to a fixing piece for fixing the traction rope 4. Figure 2 As shown, the fixing member includes a mounting plate 205, a connecting tube 206 and a connecting head 207. The mounting plate 205 is fixedly connected to one side of the anchoring beam body 2. In this embodiment, the mounting plate 205 is fixedly connected to the front side of the anchoring beam body 2 (with a connecting tube 206). Figure 1 The connecting tube 206 is located on one side of the mounting plate 205 and is welded and fixed to the mounting plate 205. The connecting head 207 is connected to the connecting tube 206. In this embodiment, the connecting head 207 is threadedly connected to the connecting tube 206. One end of the traction rope 4 is connected to the connecting head 207. In this embodiment, the connecting head 207 has a fixing ring. One end of the traction rope 4 can be fixed to the fixing ring by hooking it or by other fixing methods. No specific limitation is made here. Those skilled in the art can select the fixing method according to actual conditions.
[0038] like Figure 1 As shown, in this embodiment, two fixing members are provided, the two fixing members are symmetrically arranged, and the two fixing members are centrally arranged, so that the connection of the maintenance platform 3 is more balanced in the later stage.
[0039] In this embodiment, a hanging seat 203 is connected to the top of the anchoring beam body 2, and a hanging hole 204 is opened on the hanging seat 203. There are two hanging seats 203, and the two hanging seats 203 are symmetrically arranged. The arrangement of the hanging seats 203 is convenient for later lifting by a gantry crane.
[0040] Combination Figure 1 , Figure 3 and Figure 4 As shown, two sets of guide wheel assemblies are provided on the anchoring beam body 2, and the number of guide wheel assemblies in each set is two, and the two guide wheel assemblies in each set are respectively located at the upper part and the lower part of the anchoring beam body 2. Both sets of guide wheel assemblies include guide wheels 201 and fixing seats 202, and each set of guide wheel assemblies has two fixing seats 202, which are fixed to the anchoring beam body 2 by screws, and the two ends of the guide wheel 201 are respectively rotatably connected to the two fixing seats 202 by bearings, and the guide wheels 201 of the two sets of guide wheel assemblies can respectively roll vertically along the side walls of the two gates 101.
[0041] In this embodiment, both guide wheel assemblies are located on the same side as the fixing member. Figure 4 As shown, a guide rail 102 is vertically arranged on the inner side of the gate 101 , and the guide wheel 201 rolls vertically along the guide rail 102 .
[0042] The specific implementation process is as follows:
[0043] The anchoring beam body 2 and the winch on the maintenance platform 3 working vehicle are connected to the connector 207 in the fixing part through the traction rope 4 (wire rope), and then the existing gantry crane on site is used to lift them down along the gate 101 of the dam. The gate 101 restricts its left and right movement. When the anchoring beam body 2 reaches the top of the slope of the flood discharge channel 1, the gate 101 and the top of the flood discharge channel 1 restrict its left and right and downward movement. Then the maintenance platform 3 is towed to the designated position by the traction force of the winch to start the operation.
[0044] Through this anchoring beam structure, the damage to the original structure of the dam is avoided. At the same time, the anchoring beam structure is more stable and reliable than installing anchor points above the dam because of its own structural stability and high strength, and it uses the slope tops of the gate 101 and the flood discharge channel 1 for limiting. This further improves the safety and reliability of the original solution.
