A device for replacing road manhole covers

Abstract

The invention discloses a device for replacing a road manhole cover, which includes a vehicle body, and is characterized in that: the upper side of the bearing plate of the vehicle body is fixedly connected to the lower end of a symmetrical support plate, and the upper ends of the two support plates are respectively fixedly connected to the lower end of the sleeve. One end of the sleeve, one end of the sleeve is fixedly connected to motor one, the output end of the motor one passes through the sleeve, the output end of the motor one is fixedly connected to one end of the lead screw, one end of the guide cylinder is embedded in the sleeve and the other One end, the other end of the lead screw is threaded and passes through one end of the guide cylinder, and the other end of the lower side of the guide cylinder is fixedly connected to the middle part of the upper side of the installation plate. The present invention relates to the field of manhole cover replacement, in particular, to a road Device for manhole cover replacement. This device can adjust the distance between a group of fixed plates according to the size of the well circle, and fix the well circle through a set of fixed plates, which is convenient for the disassembly and installation of the well circle, and at the same time avoids the displacement of the well circle when filling the road occur.

Description

technical field [0001] The invention relates to the field of manhole cover replacement, in particular to a device for replacing road manhole covers. Background technique [0002] Manhole covers are common facilities on highways and are used to cover the maintenance entrances of urban livelihood facilities such as underground water pipes and optical cables. Because there are many vehicles on the road, it is easy to cause the manhole cover to sink over time. The main reason for the manhole cover sinking is that the well circle is damaged. It is necessary to replace the new well circle in time to avoid a greater safety hazard to the passing vehicles. The current The replacement of manhole covers and well circles mainly relies on hand-held tools to move and replace manhole covers and well circles. The labor intensity is high, and the operation is slow, resulting in low work efficiency. When replacing the well circles, the road near the well circles needs to be broken. , take ou...

Because there are many vehicles on the road, it is easy to cause the manhole cover to sink over time. The main reason for the manhole cover sinking is that the well circle is damaged. It is necessary to replace the new well circle in time to avoid a greater safety hazard to the passing vehicles. The current The replacement of manhole covers and well circles mainly relies on hand-held tools to move and replace manhole covers and well circles. The labor intensity is high, and the operation is slow, resulting in low work efficiency. When replacing the well circles, the road near the well circles needs to be broken. , take out the well ring and install the well ring, and then repair the road surface after the replacement, but at present, when filling the road, it is difficult to fix the well ring, and it is easy to cause the shift of the well ring, so it is urgent to make a road manhole cover replacement device
