Description

Technical Field

[0001] The utility model relates to the technical field of safety locking, in particular to a safety locking device for a maintenance platform. Background Art

[0002] Due to long-term flood discharge, the flood discharge walls on both sides of the flood discharge channel of the hydropower station have different degrees of erosion and wear, so regular maintenance is required. During maintenance, a fixed maintenance platform needs to be installed in the flood discharge channel, and manual maintenance work is carried out on the maintenance platform. However, due to the limitations of construction conditions and environment, it is difficult to ensure that the maintenance platform is in a stable state, which easily leads to slippage of the maintenance platform, causing certain safety hazards.

[0003] Therefore, in order to ensure that the maintenance platform does not slip during construction, a safe and reliable locking device needs to be developed on the base of the maintenance platform. Utility Model Content

[0004] The utility model provides a safety locking device for an inspection and repair platform, the purpose of which is to ensure that the inspection and repair platform does not slip during construction.

[0005] The utility model is achieved through the following technical scheme: a safety locking device for a maintenance platform, which is installed on the base of the maintenance platform and includes a locking block and a telescopic driving unit capable of generating telescopic movement, wherein the locking block is connected to the base of the maintenance platform through the telescopic driving unit, and the telescopic movement of the telescopic driving unit can drive the locking block to move in a direction away from or close to the base of the maintenance platform.

[0006] Compared with the prior art, this solution has the following advantages and beneficial effects:

[0007] In the present solution, the telescopic movement of the telescopic drive unit can drive the locking block to move away from or towards the base of the maintenance platform. When the telescopic drive unit moves outward, it will drive the locking block to move to the side wall of the flood discharge channel and fit closely therewith, thereby fixing the maintenance platform. This can provide resistance to the maintenance platform to prevent the maintenance platform from slipping during construction operations. The telescopic drive unit can generate telescopic movement, so that the position of the locking block and the tightness of the lock can be adjusted according to the actual width of the flood discharge channel. It is convenient and flexible to use and has a wide range of applications.

[0008] Furthermore, the telescopic drive unit is a hydraulic cylinder or a gas cylinder, the cylinder body of the telescopic drive unit is connected to the maintenance platform base, and the telescopic rod of the telescopic drive unit passes through the maintenance platform base and is connected to the locking block.

[0009] Beneficial effects: In this solution, the telescopic drive unit adopts a hydraulic cylinder or an air cylinder. The telescopic movement of the telescopic rod can drive the locking block to move freely to press against the side wall of the flood discharge channel to ensure the stability and safety of the maintenance platform. At the same time, the reverse movement of the telescopic rod can quickly make the maintenance platform movable, which is convenient for moving to different positions for maintenance work.

[0010] Furthermore, one end of the locking block facing the telescopic drive unit is connected to a connecting tube, and the telescopic rod of the telescopic drive unit is coaxially connected to the connecting tube.

[0011] Beneficial effect: In this solution, a connecting tube is connected to the locking block, so that the connecting tube is more convenient to be connected to the telescopic rod.

[0012] Furthermore, a mounting plate is coaxially connected to the end of the connecting tube, and the mounting plate is connected to the locking block.

[0013] Beneficial effect: The setting of the mounting plate facilitates connection and fixation with the locking block through fasteners, thereby achieving the purpose of connecting and fixing the connecting cylinder and the locking block.

[0014] Furthermore, the telescopic rod of the telescopic drive unit is threadedly connected to the connecting tube.

[0015] Beneficial effects: In this solution, the connecting tube and the telescopic rod are connected and fixed by means of threaded connection, which is simple and convenient to operate and easy to disassemble and replace. In this way, they can be assembled on site and quickly installed on the base of the maintenance platform.

[0016] Furthermore, the outer side of the connecting tube is provided with two or more flat concave surfaces which are evenly arranged in the circumferential direction.

[0017] Beneficial effect: With this arrangement, it is convenient to use a disassembly tool for tightening or loosening the connecting tube by clamping it on the concave surface for screwing.

[0018] Furthermore, it also includes a connecting plate, which is located between the cylinder end of the telescopic drive unit and the base of the maintenance platform, and the cylinder end of the telescopic drive unit is connected to the connecting plate.

[0019] Beneficial effect: The setting of the connecting plate in this solution can play the role of a cushion block, so that when the telescopic drive unit is fixed, a pressing force can be generated, so that the connection between the telescopic drive unit and the base of the maintenance platform is tighter.

[0020] Furthermore, guide rods are provided on both sides of the telescopic drive unit, and overlapping through holes are provided on the inspection platform base and the connecting plate. One end of the guide rod is connected to the locking block, and the other end of the guide rod passes through the through holes of the inspection platform base and the connecting plate in turn and can slide axially in the through holes.

[0021] Beneficial effect: The setting of the guide rod can guide the movement of the locking block, improve the stability of the movement of the locking block, and thus improve the tightness of the fit between the locking block and the side wall of the flood discharge channel.

[0022] Furthermore, a guide cylinder is coaxially slidably fitted on the guide rod, and the guide cylinder is inserted into the through holes on the maintenance platform base and the connecting plate. The end of the guide cylinder is connected to a fixing plate, and the fixing plate is located outside the through hole of the connecting plate and is connected to the connecting plate, and the guide rod can pass through the fixing plate.

[0023] Beneficial effect: The setting of the guide cylinder in this solution enables the guide rod to slide axially with it, thereby playing a guiding role. This can prevent the guide rod from directly contacting the base of the maintenance platform, thereby avoiding wear on the maintenance platform. Even if the guide cylinder is worn, it is easy to replace. The setting of the fixed plate in this solution facilitates fixing the position of the guide cylinder and maintaining the stability of the guide cylinder.

[0024] Furthermore, one end of the locking block away from the telescopic driving unit is connected to a rubber pad.

[0025] Beneficial effects: The provision of the rubber pad can prevent damage to the flood discharge channel while being tightly attached to the flood discharge channel, and can also increase the friction between the rubber pad and the flood discharge channel, resulting in a better locking effect.
