Description

Technical Field

[0001] This utility model relates to the field of auxiliary construction, and in particular to a tool for the overall lifting and installation of bluestone slab manhole covers for ancient buildings. Background Technology

[0002] Manhole cover lifting tools are auxiliary construction supplies used to facilitate the installation and maintenance of manhole covers during construction. Their purpose is to improve work efficiency and facilitate the opening of manhole covers during construction and subsequent maintenance and inspection. Without manhole cover lifting tools, or with tools that are not suitable for the actual needs of the site, construction efficiency will decrease, and even the finished manhole covers may be damaged, threatening the safety of workers and causing economic losses. Therefore, suitable manhole cover lifting tools are essential during construction, especially for the large and heavy manhole covers in this project. Ordinary manhole covers are difficult to install without professional lifting tools, and subsequent maintenance will be difficult; therefore, professional lifting tools are absolutely necessary for manhole cover lifting.

[0003] However, since the ancient bluestone slab manhole covers are invisible manhole covers, the outer frame of the ancient bluestone slab manhole covers is usually fixed by the surrounding paving. Once the ancient bluestone slab manhole cover is tightly connected to the outer frame during installation, the manhole cover lifting tool may lift the outer frame and the manhole cover together during the lifting process, resulting in damage to the surrounding paving. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing a convenient, easy-to-move, anti-lifting, stable lifting tool for the overall lifting and installation of ancient bluestone slab manhole covers, saving time, effort, and increasing efficiency.

[0005] To achieve the above objectives, this utility model first proposes a tool for the overall lifting and installation of ancient bluestone slab manhole covers. It includes a rectangular support frame formed by four horizontal beams connected end-to-end. An opening area matching the size of the bluestone slab manhole cover is formed in the middle of the support frame. Liftable walking mechanisms are installed on the bottom surface of the support frame at the four corners. Multiple sliding sleeves are slidably fitted onto the two opposing horizontal beams of the support frame. Locking mechanisms are installed on the sliding sleeves to lock their sliding positions on the horizontal beams. Vertically arranged jacks and manhole cover lifting devices matching the manhole cover's lifting hole are installed on the sliding sleeves. The jacks include a support section and a lifting section. The lifting section of the jack is fixedly connected to the sliding sleeves. The support section faces the ground. An outer frame pressing mechanism is hinged to the support section of the jack on the side facing the opening area. The outer frame pressing mechanism includes a telescopic rod and a support base plate. One end of the telescopic rod is hinged to the jack, and the other end is hinged to the support base plate.

[0006] In this embodiment, the manhole cover lifting device includes a wire rope and a lifting plate. A slide rail is provided on the bottom side of the sliding sleeve. The slide rail is located on the side of the jack near the opening area. A slider is installed inside the slide rail. One end of the wire rope is installed on the slider through a ball joint, and the other end is fixed with a lifting plate. The size of the lifting plate corresponds to the size of the manhole cover lifting hole on the bluestone manhole cover body.

[0007] In this embodiment, the slide rail is in the shape of a straight line.

[0008] In this embodiment, a handle is installed on the crossbeam on one side of the support frame to facilitate moving the support frame.

[0009] In this embodiment, the telescopic rod is a screw telescopic structure.

[0010] In this embodiment, an anti-slip layer is fixed on the bottom surface of the support base plate.

[0011] In this embodiment, the lifting and walking mechanism includes a rotary handle, a lead screw, and casters. The support frame has a threaded through hole along the vertical direction. The lead screw is threadedly installed in the threaded through hole. The upper end of the lead screw extends from the top of the support frame and a rotary handle is fixed thereon. The lower end of the lead screw extends from the bottom of the support frame and a caster is installed thereon.

[0012] In this embodiment, the caster wheel is a caster wheel with a locking device.

[0013] With the above structure, this utility model has the following advantages:

[0014] 1. This device, through its support frame and lifting mechanism, can be easily moved to the top of the bluestone manhole cover. By cooperating with the jack, the outer frame pressing mechanism and the manhole cover lifting device, it can lift the bluestone manhole cover while effectively preventing the outer frame from being lifted along with the bluestone manhole cover due to the tight connection between the bluestone manhole cover and the outer frame, thus protecting the surrounding paving from damage.

[0015] 2. The outer frame pressing mechanism of this device adjusts the length of the telescopic rod so that the support base plate is placed on the outer frame of the manhole cover. The telescopic rod forms the diagonal support of the jack. Under the action of the jack, the telescopic rod is always pressed down on the outer frame of the manhole cover, forming a reaction force with the lifting force of the bluestone manhole cover body, preventing the movement of the outer frame of the manhole cover, and further preventing the bluestone manhole cover body from separating from the outer frame of the manhole cover.

[0016] 3. The manhole cover lifting device uses a combination of wire rope and lifting plate. The wire rope is flexible and, together with the slide rail and ball joint design, it not only makes it easy for the lifting plate to be aligned with and connected to the lifting hole of the bluestone manhole cover, but also allows the manhole cover lifting device to adapt to different models of manhole covers and lifting holes in different positions. After the lifting plate is inserted, the lifting plate and the lifting hole are staggered and locked by rotating the wire rope, forming a reliable hook function to ensure the stability of the manhole cover during the lifting process.

[0017] 4. The lifting and walking mechanism includes a rotary handle, a lead screw, and casters with locking devices. The lifting and lowering of the casters and the locking of the support frame are achieved by rotating the handle to control the lifting and lowering of the lead screw, which facilitates the movement of the bluestone manhole cover body after it is lifted. At the same time, the lead screw can also be equipped with a scale to make it easy to accurately level the four casters, improve the efficiency of subsequent leveling, and improve the stability of transportation.

[0018] In summary, the overall construction process of this device is clearly defined. From moving and positioning the device, adjusting the jacks and the outer frame pressing mechanism, to connecting the manhole cover to the lifting and moving, each step works closely together. Compared with traditional manual lifting and handling, it saves more time and effort and effectively improves the efficiency of installation. Attached Figure Description

[0029] like Figures 1 to 7 As shown, a tool for lifting and installing bluestone manhole covers for ancient buildings includes a rectangular support frame 2 formed by four horizontal beams connected end to end. The middle of the support frame 2 forms an opening area that matches the size of the bluestone manhole cover body 81. Liftable walking mechanisms 3 are installed on the bottom surface of the support frame 2 at the four corners. A push handle 1 for easy movement of the support frame 2 is installed on one side of the horizontal beam. Multiple sliding sleeves 4 are slidably fitted on the horizontal beams near the push handle 1 on both sides of the support frame 2 (in this embodiment, two sliding sleeves 4 are fitted on each horizontal beam). Locking mechanisms are installed on the sliding sleeves 4. Mechanism 41 (in this embodiment, locking mechanism 41 includes a locking screw, and the sliding sleeve 4 is provided with a threaded through hole, the locking screw being threadedly installed in the threaded through hole), the sliding sleeve 4 can slide along the crossbeam, and the relative position of the sliding sleeve 4 on the crossbeam is locked by locking mechanism 41. A vertically arranged jack 5 and a manhole cover lifting device 7 matching the manhole cover lifting hole 84 are installed on the bottom side of the sliding sleeve 4. The manhole cover lifting device 7 is set on the side of the jack 5 near the opening area. The manhole cover lifting device 7 includes a wire rope 72 and a lifting plate 73. A slide rail 71 is provided on the bottom side of the sliding sleeve 4, such as Figure 6 As shown, the slide rail 71 is straight and extends from the jack 5 towards the opening area. The slide rail 71 can also be circular or other shapes to increase the range of movement of the wire rope 72, facilitating subsequent hole alignment. A slider is installed inside the slide rail 71, allowing it to slide freely within the rail. One end of the wire rope 72 is mounted on the slider via a ball joint, and a hanging plate 73 is fixed to the other end. Figure 5 , 7 As shown, the size of the lifting plate 73 corresponds to the size of the lifting hole 84 on the bluestone manhole cover body 81, and both are long strips.

[0030] like Figure 4 As shown, the jack 5 includes a support section and a lifting section. The lifting section of the jack 5 is fixedly connected to the bottom side of the sliding sleeve 4. The support section faces the ground. An outer frame pressing mechanism 6 is hinged on the support section of the jack 5 on the side facing the opening area. The outer frame pressing mechanism 6 includes a telescopic rod 61 and a support base plate 62. The telescopic rod 61 is a screw telescopic structure. One end of the telescopic rod 61 is hinged to the jack 5, and the other end is hinged to the support base plate 62. Preferably, the minimum length of the telescopic rod 61 is not less than the height of the support section of the jack 5, and an anti-slip layer is fixed on the bottom surface of the support base plate 62.

[0031] like Figure 1 , 2 As shown, the lifting and walking mechanism 3 includes a rotary handle 31, a lead screw 32, and casters 33. The support frame 2 has a threaded through hole along the vertical direction. The lead screw 32 is threaded into the threaded through hole. The upper end of the lead screw 32 extends from the top of the support frame 2 and the rotary handle 31 is fixed thereon. The lower end of the lead screw 32 extends from the bottom of the support frame 2 and the casters 33 are mounted thereon. The casters 33 are casters 33 with locking devices. The locking devices can lock the casters 33 so that they do not rotate, thereby locking the position of the support frame 2. The lead screw 32 can be rotated by rotating the rotary handle 31, and the lifting and lowering of the casters 33 is controlled by the lifting and lowering of the lead screw 32. Furthermore, the lead screw 32 is provided with a scale, which makes it easy to level the four casters 33.

[0032] The construction process of the bluestone slab manhole cover body 81 using this device is as follows:

[0033] a. Move the device directly above the bluestone manhole cover body 81 using the pusher 1, so that the bluestone is placed in the opening area. Further fine-tune the position of the support frame 2 so that all the jacks 5 are placed directly above the paved road surface 83 and close to the outer frame 82 of the manhole cover.

[0034] b. Control jack 5 to move it down initially. Jack 5 can be controlled independently or in conjunction with other controls. Once jack 5 contacts the ground, control jack 5 to stop moving.

[0035] c. Adjust the outer frame pressing mechanism 6:

[0036] Adjust the length of the telescopic rod 61 so that the support base plate 62 is supported on the manhole cover frame 82. If the manhole cover frame 82 is narrow, the support base plate 62 can be supported half on the paved road surface 83 and half on the manhole cover frame 82. However, when adjusting, ensure that the support base plate 62 does not contact the bluestone manhole cover body 81. Here, the telescopic rod 61 is diagonally supported on the manhole cover frame 82.

[0037] d. Connect the manhole cover lifting device 7 to the manhole cover lifting hole 84 of the bluestone manhole cover body 81:

[0038] The wire rope 72 is moved using the slide rail 71 so that the lifting plate 73 is aligned with the manhole cover lifting hole 84. Since both the lifting plate 73 and the manhole cover lifting hole 84 are elongated, the lifting plate 73 is inserted into the manhole cover lifting hole 84. Then the wire rope 72 is rotated, and the wire rope 72 rotates around its own central axis, so that the lifting plate 73 rotates within the manhole cover lifting hole 84. Thus, the lifting plate 73 and the manhole cover lifting hole 84 are offset from each other, so that the lifting plate 73 is locked in the manhole cover lifting hole 84 to realize the lifting hook function.

[0039] e. Control the jack 5 to lift further. The jack 5 lifts the support frame 2, thereby lifting the bluestone manhole cover body 81 from the manhole cover outer frame 82. At the same time as the bluestone manhole cover body 81 is lifted, the outer frame pressing mechanism 6 presses against the manhole cover outer frame 82, preventing the bluestone manhole cover body 81 from contacting the manhole cover outer frame 82 tightly and the possibility of lifting the manhole cover outer frame 82 together.

[0040] D. When the bottom surface of the bluestone manhole cover body 81 is higher than the paved road surface 83, rotate the screw 32 by rotating the handle 31 to drive the universal wheel 33 to move downward until the bottom of the jack 5 is separated from the ground. At this time, the support frame 2 is supported by the universal wheel 33. Then control the jack 5 to retract, and then push the support frame 2 by the pusher 1 to move the bluestone manhole cover body 81 away from the manhole.

[0041] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the concept of this utility model and the contents of the specification and drawings of this utility model, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
