Description

Technical Field

[0001] This utility model relates to a manhole construction auxiliary device, specifically a municipal manhole construction auxiliary device, and belongs to the technical field of manhole auxiliary devices. Background Technology

[0002] Municipal manholes are an important component of municipal infrastructure such as water supply and drainage systems, power systems, and communication systems. They are usually located underground in public places such as urban roads and squares to inspect, maintain, and manage underground pipelines and cables. The manhole shell is the main part of the manhole and is usually made of materials such as concrete or brick in the shape of a circle or square. Therefore, when hoisting the manhole shell, an auxiliary tool is often used to lift the manhole shell component smoothly and place it accurately in the predetermined construction position, which greatly improves construction efficiency.

[0003] However, traditional shaft hoisting auxiliary devices often utilize the lever principle to make two top support rods abut against the inner wall of the shaft. When the lifting device lifts upward, the two top support rods rotate around the fulcrum, thereby clamping the inner wall of the shaft. Under the action of friction, the shaft is lifted and transported to the construction position. However, since the position of the fulcrum is constant or fixed at a designated location by bolts, when it is necessary to hoist shafts with different inner diameters, it is necessary to change the lifting tools of different sizes or adjust the position of the fulcrum by disassembling the bolts. The operation process is cumbersome and lacks flexibility. Utility Model Content

[0004] The purpose of this utility model is to provide an auxiliary device for the construction of municipal pipe wells in order to solve the above problems. The device uses a lead screw to drive two sliders to slide in opposite directions. The sliders drive two clamping rods and the first rotating shaft to move in opposite directions, thereby increasing the distance between the two clamping rods. This makes it easier to clamp and fix wells with different inner diameters and has high adjustment efficiency.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4As shown, a municipal manhole construction auxiliary device includes a main beam 1, on which an adjustment structure 2 is installed. The adjustment structure 2 includes two sliders 201. The sliders 201 are slidably connected to the inner wall of the main beam 1. Two guide rods 204 are fixedly connected inside the main beam 1. The sliders 201 and guide rods 204 are slidably connected. A first rotating shaft 202 is fixedly connected to the sliders 201. A clamping rod 203 is rotatably connected to the first rotating shaft 202. Both ends of the main beam 1 are threadedly connected to lead screws 205. The ends of the lead screws 205 are connected to the adjacent sliders. The blocks 201 are rotatably connected. A stop block 206 is fixedly connected to one end of the lead screw 205 near the slider 201. The side of the stop block 206 near the slider 201 abuts against the slider 201. A knob 207 is fixedly connected to one end of the lead screw 205 near the outer side. The other end of the lead screw 205 has a "T"-shaped structure. A bottom cover 208 is fixedly connected to the bottom surface of the main beam 1. The slider 201 is slidably connected to the upper surface of the bottom cover 208. The clamping rod 203 has a "V"-shaped structure, and the two clamping rods 203 are symmetrically arranged. The bottom is provided with an abutment structure 3, and the top of the clamping rod 203 is fitted with a driving structure 4. First, adjust the position of the two sliders 201 inside the main beam 1 according to the inner diameter of the shaft to be hoisted. When it is necessary to increase the distance between the two clamping rods 203, simply rotate the knobs 207 at both ends of the main beam 1 in sequence. Then, the knobs 207 drive the lead screw 205 to rotate. Since the lead screw 205 is threadedly connected to the main beam 1 and its end is rotatably connected to the slider 201, the lead screw 205 moves outward towards the main beam 1, driving the slider 201 along the two guide rods 204 towards the main beam 1. Sliding outwards, the two sliders 201 drive the two first rotating shafts 202 and the clamping rods 203 to slide to both sides, thus effectively adjusting the distance between the two clamping rods 203. This provides high flexibility and facilitates clamping well shafts of different inner diameters, improving practicality. At the same time, the stop block 206 at the end of the lead screw 205 can effectively limit the slider 201, preventing relative sliding between the slider 201 and the guide rod 204, thus ensuring high stability. Furthermore, by removing the bottom cover 208 at the bottom of the main beam 1, it is convenient to replace and repair the internal parts of the main beam 1, making the operation simple.

[0022] As a technical optimization of this utility model, the contact structure 3 includes an adjusting plate 301. The bottom of the clamping rod 203 is provided with the adjusting plate 301. A rubber pad 302 is fixedly connected to the side of the adjusting plate 301 near the outer side. The adjusting plate 301 and the clamping rod 203 are fixedly connected by two bolts 303. The ends of the bolts 303 abut against the rubber pad 302. Since the adjusting plate 301 is installed at the bottom of the clamping rod 203 by two bolts 303, it is convenient to flexibly adjust the position of the adjusting plate 301 by removing the bolts 303, thereby increasing the length of the adjusting plate 301 extending into the well shaft and improving the firmness. Furthermore, since the rubber pad 302 is fixedly connected to the adjusting plate 301, the friction between it and the inner wall of the well shaft is effectively increased, improving the firmness of the contact.

[0023] As a technical optimization of this utility model, the driving structure 4 includes a connecting block 401. The connecting block 401 is fixedly connected to the center of the main beam 1. The guide rod 204 passes through the connecting block 401. A second rotating shaft 402 is fixedly connected to the top of the connecting block 401. A driving rod 403 is rotatably connected to the second rotating shaft 402. The top of the clamping rod 203 has four through holes 405. A hook 406 abuts against the inside of one of the through holes 405. A steel wire rope 407 is provided between the hook 406 and the top of the driving rod 403. A lifting ring 404 is slidably connected to the top surface of the driving rod 403. The end of the steel wire rope 407 is fixedly connected to the lifting ring 404. The four through holes 405 are equidistantly arranged. When the two are adjusted... The spacing between the clamping rods 203 is adjusted, and after the two clamping rods 203 are extended into the well shaft from the port, the drive rod 403 is rotatably connected to the connecting block 401 at the center of the main beam 1 via the second rotating shaft 402. Since the top of the drive rod 403 is connected to the crane via the lifting ring 404, and the wire rope 407 at the top of the drive rod 403 is not fully taut, when the crane moves the lifting ring 404 upward, the lifting ring 404 will cause the wire rope 407 to tighten. The wire rope 407, through the hook 406 and the through hole 405, causes the clamping rods 203 to rotate around the first rotating shaft 202 towards the drive rod 403. Thus, the bottom of the two clamping rods 203 causes the rubber pad 302 to press against the inner wall of the well shaft. At this time, the well shaft can be lifted and transferred to the construction site, resulting in high operational efficiency.

[0024] In use, this invention first adjusts the positions of the two sliders 201 inside the main beam 1 according to the inner diameter of the shaft to be hoisted. When it is necessary to increase the distance between the two clamping rods 203, simply rotate the knobs 207 at both ends of the main beam 1 in sequence. The knobs 207 then drive the lead screw 205 to rotate. Since the lead screw 205 is threadedly connected to the main beam 1 and its end is rotatably connected to the slider 201, as the lead screw 205 moves outward from the main beam 1, it drives the slider 201 to slide along the two guide rods 204 outward from the main beam 1. The two sliders 201 respectively... The two first rotating shafts 202 and clamping rods 203 slide to both sides, effectively adjusting the distance between the two clamping rods 203. This provides high flexibility and facilitates clamping well shafts of different inner diameters, improving practicality. Simultaneously, the stop block 206 at the end of the lead screw 205 effectively limits the slider 201, preventing relative sliding between the slider 201 and the guide rod 204, ensuring high stability. Furthermore, removing the bottom cover 208 at the bottom of the main beam 1 facilitates the replacement and maintenance of internal parts, simplifying operation. Additionally, the bottom of the clamping rods 203 is connected by two... Bolt 303 is fitted with an adjusting plate 301, which allows for flexible adjustment of the position of the adjusting plate 301 by removing bolt 303. This increases the length of the adjusting plate 301 extending into the well shaft, improving stability. Furthermore, the rubber pad 302 fixedly connected to the adjusting plate 301 effectively increases the friction between it and the inner wall of the well shaft, enhancing the stability of the contact. After adjusting the distance between the two clamping rods 203 and extending them into the well shaft from their ends, a drive rod is rotatably connected to the connecting block 401 at the center of the main beam 1 via the second rotating shaft 402. 403, and since the top of the drive rod 403 is connected to the crane via the lifting ring 404, and the wire rope 407 at the top of the drive rod 403 is not fully taut, when the crane moves the lifting ring 404 upward, the lifting ring 404 will cause the wire rope 407 to tighten, and the wire rope 407 will cause the clamping rod 203 to rotate around the first rotating shaft 202 towards the drive rod 403 through the lifting buckle 406 and the through hole 405. Thus, the bottom of the two clamping rods 203 will cause the rubber pad 302 to press against the inner wall of the well shaft. At this time, the well shaft can be lifted and transferred to the construction site, with high operating efficiency.
