Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of manhole cover processing fixtures, in particular to a fixture for processing ductile iron round manhole covers. Background Art
[0002] In order to increase the durability of urban roads, a concrete and asphalt structure is usually used. The concrete has a dense texture and poor water permeability, which can easily cause urban waterlogging during the rainy season. Therefore, corresponding sewers need to be laid during the construction of urban roads to drain urban water in a timely manner. Sewers must have sewer outlets, and manhole covers need to be installed on the sewer outlets to prevent passers-by from falling into the sewer outlets while facilitating the inspection and cleaning of the sewers.
[0003] At present, manhole covers are mostly made of ductile iron, and they need to be clamped and fixed during processing. However, the existing clamping equipment uses rigid clamps to clamp the manhole covers. When the outer surface of the manhole cover is uneven, the force applied to the clamps will be uneven, and the rigid clamps have no buffer structure during clamping, which can easily cause mechanical interference and damage the contact parts of the clamps. Utility Model Content
[0004] In order to solve the existing technical problems, the utility model provides a fixture for processing ductile iron round manhole covers. In order to solve the above technical problems, the basic concept of the technical solution adopted by the utility model is:
[0005] A clamp for processing ductile iron round manhole covers comprises a base, a storage groove is provided on the top of the base, an inner cavity is provided inside the base, a pad is fixed at the middle of the inner bottom surface of the storage groove, slideways that penetrate into the inner cavity are provided near the two side edges of the inner bottom surface of the storage groove, sliders are slidably connected to the inside of the two slideways, arc-shaped clamping plates are fixed on the top of the two sliders, and rubber pads are provided on one side of the two arc-shaped clamping plates. When clamping, the rubber pads on one side of the arc-shaped clamping plates contact with the outer surface of the manhole cover, so that the contact part can be buffered by the rubber pads when an impact occurs, thereby preventing damage to the mechanical parts of the clamping part.
[0006] Optionally, a plurality of slots are equidistantly formed on one side of the two arc-shaped clamping plates, and one side of the rubber pads is correspondingly extended to be engaged in the inside of the slots.
[0007] Optionally, both ends of the two arc-shaped clamping plates are rotatably connected to guide rollers. When the arc-shaped clamping plates contact the outer surface of the manhole cover, the edges of the arc-shaped clamping plates pass through the guide rollers to prevent scratches on the outer surface of the manhole cover.
[0008] Optionally, the bottoms of the two sliders are rotatably connected to pull rods, a driving plate is provided inside the inner cavity, one ends of the two pull rods are correspondingly rotatably connected to the outer surfaces on both sides of the driving plate, a stroke cylinder is fixed to the inner bottom surface of the inner cavity, the output end of the stroke cylinder is fixed to the bottom of the driving plate, and the driving plate is driven downward by starting the stroke cylinder, thereby driving the pull rods to pull the two sliders to the middle part of the storage slot.
[0009] Optionally, side supports are fixed on both sides of the base, and a vertical plate is fixed on the rear side of the base.
[0010] Optionally, an electric slide rail is fixed to the front side of the vertical plate, a cantilever is fixed to the front side of the electric slide rail, and one end of the cantilever extends to just above the base.
[0011] After adopting the above technical solution, the utility model has the following beneficial effects compared with the prior art. Of course, any product implementing the utility model does not necessarily need to achieve all the advantages described below at the same time:
[0012] 1. In the utility model, the manhole cover is placed inside the storage tank and supported by a pad, and then the manhole cover is clamped and fixed by two arc-shaped clamping plates. When clamping, the rubber pad on one side of the arc-shaped clamping plate contacts the outer surface of the manhole cover, so that when an impact occurs, the contact part can be buffered by the rubber pad to prevent damage to the mechanical parts of the clamping part.
[0013] 2. In the utility model, when the two arc-shaped clamping plates move, the driving plate is driven to move downward by starting the stroke cylinder, thereby driving the pull rod to pull the two sliders to the middle part of the storage slot, thereby driving the arc-shaped clamping plates to clamp the manhole cover. When the arc-shaped clamping plates contact the outer surface of the manhole cover, the edges of the arc-shaped clamping plates are prevented from being scratched by the guide rollers on the outer surface of the manhole cover. The cantilever is connected to the vertical plate through an electric slide rail, so that the cantilever can be driven to move up and down under the action of the electric slide rail. In actual use, the equipment for processing the manhole cover is installed on the cantilever to facilitate the processing of the manhole cover. BRIEF DESCRIPTION OF THE DRAWINGS
