Description

Technical Field

[0001] This utility model belongs to the field of municipal construction technology, and in particular relates to an auxiliary device for the construction of municipal pipe wells. Background Technology

[0002] Municipal infrastructure engineering refers to civil engineering, pipeline, and equipment installation projects for urban roads, public transportation, etc. A well is a vertically installed tubular structure for drawing or protecting groundwater. It is a water supply and drainage facility used in industrial and agricultural production, urban areas, transportation, and national defense. Wells have a small diameter and considerable depth, and are used to extract deep or shallow groundwater. Wells drilled into confined aquifers, where the water head is above ground level, are also called artesian wells.

[0003] In the existing technology, when constructing municipal pipe wells, workers are generally required to remove the manhole cover. However, due to the large weight of the manhole cover, multiple workers are usually needed to lift and move it, which wastes a lot of manpower and increases the labor intensity of the workers. Therefore, an auxiliary device for municipal pipe well construction is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide an auxiliary device for the construction of municipal pipe wells to solve existing problems.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0027] Please see Figures 1-4As shown, this utility model is an auxiliary device for the construction of municipal manholes, including an auxiliary platform 1 and connecting rods 2. Two mounting slots 101 are formed on the upper surface of the auxiliary platform 1. Ball screws 102 are rotatably installed inside each of the two mounting slots 101. Screw nuts 103 are threaded onto the circumferential sides of each of the two ball screws 102. There are two connecting rods 2, welded to the lower surfaces of the two screw nuts 103. An auxiliary frame 201 is welded to the lower surface of each of the two connecting rods 2. An auxiliary pipe 203 is welded to the lower surface of each of the two auxiliary frames 201. Opening slots 204 are formed on both sides of the lower end of each of the four auxiliary pipes 203. A connecting shaft 205 is installed inside each of the four opening slots 204. Rotating lifting plates 206 are rotatably installed on the circumferential sides of each of the four connecting shafts 205. This allows the two rotating lifting plates 206 to open and be positioned on the lower surface of the manhole cover after the auxiliary pipe 203 is inserted through the cover hole. Then, in conjunction with a hydraulic rod 3, the manhole cover is lifted, eliminating the need for manual handling and assisting workers in construction, thus reducing their workload.

[0028] An elastic pull strap 207 is fixedly installed between the lower ends of the two rotating lifting plates 206. The bottom surface of the two auxiliary frames 201 is provided with through holes 202, which are connected to the interior of the two auxiliary tubes 203. Electric push rods 208 are welded to the top surface of the interior of the two auxiliary frames 201.

[0029] Two electric push rods 208 are keyway connected to adjusting plates 209 at their lower ends. The lower ends of the two adjusting plates 209 extend into the auxiliary tube 203 through through holes 202. The lower ends of the two adjusting plates 209 contact the elastic pull belt 207, which facilitates the control of opening and lifting of the rotating lifting plate 206. This allows for easy adjustment according to the workflow and improves the convenience of using the device. Drive motors 104 are fixedly installed on the front and rear surfaces of the auxiliary platform 1. One end of the two ball screws 102 extends to the outside of the auxiliary platform 1. The output ends of the two drive motors 104 are keyway connected to one end of the ball screws 102, which facilitates the adjustment of the position of the auxiliary tube 203 according to the position of the cover hole of different manhole covers, thus improving the flexibility of using the device.

[0030] The two mounting slots 101 have two opposite surfaces with sliding grooves 105. Sliding sliders 106 are slidably installed inside the two sliding grooves 105. One end of each sliding slider 106 extends to the outside of the two sliding grooves 105. One end of each sliding slider 106 is fixedly connected to the lead screw nut 103.

[0031] Hydraulic rods 3 are welded to the lower surface of the auxiliary platform 1. A movable plate 4 is welded to the lower surface of the two hydraulic rods 3. Support rods 5 are welded to both ends of the lower surface of the two movable plates 4. Pulleys 6 are bolted to the lower ends of the four support rods 5. A brake pad is provided on one side of the pulley 6.

[0032] Please see Figures 1-4As shown, this utility model is an auxiliary device for the construction of municipal manholes. Its usage is as follows: First, the entire device is moved above the manhole cover using pulley 6. Then, two drive motors 104 are started to drive two ball screws 102 to rotate at the same frequency, thereby moving the screw nut 103. The auxiliary pipe 203 is moved to a suitable position according to the location of the manhole cover hole. Then, the hydraulic rod 3 is started to lower it. As the hydraulic rod 3 lowers, it drives the auxiliary platform 1 and the auxiliary pipe 203 to descend. When the lower end of the auxiliary pipe 203 enters below the manhole cover, the hydraulic rod 3 is stopped. Then, the electric push rod 208 is started to drive the adjusting plate 209 to rise, causing the adjusting plate 209 to disengage from the elastic strap 207. At this time, the two rotating lifting plates 20... 6 is in a rotating state. One end of the two rotating lifting plates 206 rotates outward around the connecting shaft 205 towards the opening slot 204, so that the two rotating lifting plates 206 are in an open state. Then, the hydraulic rod 3 is activated to lift upward, and the rotating lifting plates 206 contact the lower surface of the manhole cover. When the auxiliary pipe 203 is lifted, it drives the manhole cover to lift. Then, the manhole cover is moved for construction. After the construction is completed, the manhole cover is returned to its original position. Then, the electric push rod 208 is activated to drive the adjusting plate 209 to descend, so that the adjusting plate 209 stretches the elastic band 207 downward. When the elastic band 207 is stretched, it drives the two rotating lifting plates 206 to rotate, so that the rotating lifting plates 206 are reset to the opening slot 204, making it easy to remove the auxiliary pipe 203.
