Description

Technical Field

[0001] The utility model relates to a lifting device used in municipal engineering, in particular to a pipe well construction auxiliary device used in municipal engineering. Background Art

[0002] During the construction and maintenance of municipal engineering projects, various well facilities need to be maintained and installed. During this process, manhole covers and well bases need to be installed. After installation, the manhole covers and well bases need to be regularly inspected.

[0003] In municipal engineering, the manhole seat, as the supporting structure of the manhole cover, is usually cast with concrete to ensure its stability and durability. This design aims to evenly distribute the pressure generated by vehicles or pedestrians passing through, reducing direct impact on the manhole cover, thereby extending the service life of the manhole cover and reducing maintenance costs. The main function of the manhole cover is to seal and protect the inspection well, prevent the entry of debris, and ensure the safety of pedestrians and vehicles. Therefore, the manhole cover needs to have sufficient strength and hardness, but concrete is not required. For example, common manhole cover materials include ductile iron, heavy-duty plastic-steel composite materials, etc. These materials not only ensure the sturdiness of the manhole cover, but also have certain anti-theft properties.

[0004] In the existing technology, if a manhole cover is to be opened, the operator usually uses a hook to hook the through hole on the manhole cover, and then exerts force to lift the manhole cover. However, since the manhole cover is relatively thick and heavy, this requires the operator to have a certain amount of strength. However, in the process of opening the manhole cover, the operator's waist and arms may still be injured.

[0005] When repairing the well seat, the well seat is covered with concrete, which means that during the lifting process, large pieces of concrete will be carried along, which will further increase the weight of the well seat. This requires the use of some small lifting equipment, which is not easy to transport. At the same time, purchasing lifting equipment will also increase operating costs. Utility Model Content

[0032] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] like Figure 1As shown, this embodiment provides a pipe well construction auxiliary device for municipal engineering, including a mobile trolley, which includes a platform 100 and support legs 120 arranged at the four corners of the platform 100. The bottom of the support legs 120 is provided with rollers 130, and the rollers 130 can be universal wheels or one-way wheels. A first lifting device 200 is provided on the top of the platform 100. The first lifting device 200 is fixedly connected to a lifting device 300 arranged below the platform 100. The lifting device 300 is detachably connected to the manhole cover or manhole seat. The first lifting device 200 can control the lifting device 300 to rise and fall, thereby driving the manhole cover or manhole seat to rise and fall. Second lifting devices 400 are respectively provided on both sides of the longitudinal direction of the platform 100. The second lifting device 400 can control the rise and fall of the mobile trolley as a whole.

[0034] Specifically, in this embodiment, Figure 1 As shown, the first lifting device 200 includes a drive motor 210 and a threaded rod 220. The output end of the drive motor 210 is fixedly connected to one end of the threaded rod 220. The other end of the threaded rod 220 passes through the platform 100 and is threadedly connected to the lifting device 300. The drive motor 210 rotates forward to drive the lifting device 300 to descend, and the drive motor 210 rotates reversely to drive the lifting device 300 to ascend.

[0035] In this embodiment, preferably, Figure 2 and Figure 3 As shown, the lifting device 300 includes a fixed plate 310, a guide rod 320 is fixed on the top surface of the fixed plate 310, a guide tube 110 is provided on the platform 100, and the guide rod 320 is inserted into the guide tube 110 and is slidably connected to the guide tube 110.

[0036] The threaded rod 220 is threadedly connected to the middle portion of the fixing plate 310. Specifically, a threaded sleeve 330 is provided in the middle portion of the fixing plate 310. The threaded rod 220 is inserted into the sleeve and threadedly connected to the sleeve.

[0037] The fixing plate 310 is provided with cross-shaped mounting holes 340 on both sides, and the hook 350 is movably connected to the fixing plate 310 through the mounting holes 340. Specifically, the working end of the hook 350 can be inserted into the manhole cover or the manhole seat after passing through the mounting holes 340, and the non-working end of the hook 350 is located above the fixing plate 310.

[0038] Preferably, in this embodiment, Figure 4As shown, the hook 350 includes a hanging rod 351, a baffle 352, a pad 353 and a nut 354. The non-working end of the hanging rod 351 passes through the baffle 352, the baffle 352 is located above the fixed plate 310, the pad 353 is sleeved on the hanging rod 351, and the pad 353 is located between the nut 354 and the fixed plate 310. The outer side of the hanging rod 351 is provided with an external thread, and the nut 354 is threadedly connected to the hanging rod 351 through the external thread; a cross bar 355 is provided at the bottom of the hanging rod 351.

[0039] During use, the drive motor 210 is first started, causing the drive motor 210 to rotate forward, causing the fixing plate 310 to descend to a certain height. The operator then passes one end of the hook 350 through the mounting hole 340 and inserts the working end into the through hole of the manhole cover or the through hole of the well seat. The operator then rotates the hook rod 351 so that the cross bar 355 is locked below the manhole cover or in the through hole of the well seat. Next, the drive motor 210 is started, causing the drive motor 210 to flip over so that the top surface of the fixing plate 310 contacts the bottom surface of the baffle 352, and then stops rotating. The nut 354 is then rotated to secure the hook 350 to the fixing plate 310. The drive motor 210 is then started again, causing the drive motor 210 to rotate backward, causing the fixing plate 310 to continue to rise, thereby allowing the manhole cover or the well seat to move away from the wellhead position. In this embodiment, the mounting hole 340 is cross-shaped, and the operator can adjust the position of the hook 350 according to the position of the through hole of the manhole cover or the well seat.

[0040] In addition, in this embodiment, the second lifting device 400 includes a hydraulic rod 410 and a bracket 500. One end of the bracket 500 is fixedly connected to the bottom of the platform 100, and the other end of the bracket 500 is fixedly connected to the mounting base of the hydraulic rod 410. A base plate 430 is provided on top of the piston rod 420 of the hydraulic rod 410. Some manhole covers or well seats require a considerable amount of force to be lifted out of their original position. Therefore, the hydraulic rod 410 can be used to first lift the manhole cover or well seat out of its original position, and then the drive motor 210 can be used to lift it, thereby preventing the drive motor 210 from burning out. Furthermore, if the well seat is heavy, the hydraulic rod 410 can also be used for lifting. It should be noted that the use of the first lifting device 200 and the second lifting device 400 does not conflict with each other; in different situations, they need to be used in conjunction with each other. For example, if the well seat or manhole cover needs to be lifted from a high height, both devices may need to be used together. In addition, in this embodiment, the second lifting device 400 can also be used as a supporting device. First, the mobile trolley is lifted up to make the roller 130 off the ground, and then the lifting operation is performed to ensure safety during the lifting process.

[0041] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
