Description

Technical Field

[0001] The present application relates to the technical field of manhole covers, for example, to a manhole cover with a connecting rod weight. Background Art

[0002] At present, manhole covers are often used to cover deep wells on roads or in homes to prevent people or objects from falling. Manhole covers are also used at the entrances of some escape passages. Related technology (publication number: CN107700551A) discloses an electric manhole cover, including a manhole cover and a manhole seat. The manhole cover is hinged to the manhole seat. It also includes at least one power-assisting unit. The power-assisting unit includes a fixed carrier plate fixed to the lower part of the manhole seat and a screw rod driven by a motor installed in the middle of the inner surface of the manhole cover. The sliding nut on the screw rod is hinged to one end of the support rod. The other end of the support rod is hinged to the fixed carrier plate. The fixed carrier plate is hinged to one end of a first power-assisting spring. The other end of the first power-assisting spring is hinged to the manhole cover. The manhole seat is hinged to one end of at least one second power-assisting spring. The other end of each second power-assisting spring is hinged to the manhole cover.

[0003] During the implementation of the embodiments of the present disclosure, it was found that at least the following problems exist in the related art:

[0004] It uses a lead screw and a sliding nut to convert rotational motion into linear motion. Driven by a motor and pulled or pushed by a support rod, the manhole cover is opened and closed. Due to the presence of the lead screw, sliding nut, motor and support rod, the manhole cover is large in size and therefore occupies a large space at the wellhead.

[0005] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to ordinary technicians in this field. Utility Model Content

[0006] In order to provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. The summary is not an extensive review, nor is it intended to identify key / critical elements or delineate the scope of protection of these embodiments, but rather serves as a prelude to the detailed description that follows.

[0007] An embodiment of the present disclosure provides a manhole cover with a connecting rod weight to reduce space occupation at the wellhead.

[0008] In some embodiments, the manhole cover with a connecting rod and a weight is applied to a wellhead and includes: a frame connected to the ground at the wellhead along the width direction of the wellhead; a cover plate rotatably connected to the frame for opening or closing the wellhead; a slideway connected to the inner wall of the wellhead along the length direction of the wellhead; a pulley slidably installed in the slideway; a first connecting rod, one end of the first connecting rod is rotatably connected to the pulley, and the other end of the first connecting rod is rotatably connected to the cover plate; a second connecting rod, one end of the second connecting rod is rotatably connected to the pulley; a weight rod rotatably connected to the other end of the second connecting rod, and one end of the weight rod is rotatably connected to the inner wall of the wellhead; wherein, when the wellhead is in an open or closed state, the cover plate and the weight rod are in a gravity balance state.

[0009] Optionally, it further includes: a counterweight block connected to the other end of the weight rod.

[0010] Optionally, it further includes: a hinged seat connected to the cover plate, and the other end of the first connecting rod is rotatably connected to the hinged seat.

[0011] Optionally, it further includes: a first pin shaft installed at the connection between the first connecting rod and the hinge seat.

[0012] Optionally, it further includes: a second pin installed at the connection between the pulley and the first connecting rod and the second connecting rod.

[0013] Optionally, it also includes: a third pin installed at the connection between the second connecting rod and the weight rod.

[0014] Optionally, it further includes: a rotating shaft installed at the connection between the frame and the cover.

[0015] Optionally, along the length direction of the wellhead, the frame is located on both sides of the wellhead, and the frame on both sides is rotatably connected to the cover plate.

[0016] Optionally, the slideways are located on both sides of the wellhead along the width direction of the wellhead, and the pulleys are slidably installed in the slideways on both sides.

[0017] The embodiment of the present disclosure provides a manhole cover with a connecting rod and a heavy hammer, which can achieve the following technical effects:

[0018] The disclosed embodiments provide a manhole cover with a connecting rod and a weight, which is applied to a manhole and includes a frame, a cover plate, a slide, a pulley, a first connecting rod, a second connecting rod, and a weight rod. Along the width direction of the manhole, the frame is connected to the ground at the manhole and is used to support the installation of a rotatable cover plate. The cover plate is rotatably connected to the frame and is used to open or close the manhole to provide a cover. Along the length direction of the manhole, the slide is connected to the inner wall of the manhole and is used to support the installation of a slidable pulley. The pulley is slidably installed in the slide and can move along the extension direction of the slide. One end of the first connecting rod is rotatably connected to the pulley and the other end is rotatably connected to the cover plate, so that the cover plate and the pulley move in coordination. One end of the second connecting rod is rotatably connected to the pulley and the other end is rotatably connected to the weight rod, so that the weight rod and the pulley move in coordination. One end of the weight rod is rotatably connected to the inner wall of the manhole to provide weight.

[0019] During use, the cover is rotated, and the first connecting rod pulls or pushes the pulley along the extension of the slideway. This in turn drives the second connecting rod, pulling or pushing the weight rod in rotation, causing the weight rod and the cover to rotate in unison. This ensures that gravity balances between the cover and the weight rod when the wellhead is open or closed. When the wellhead is closed, the cover and the weight rod are in gravity balance, allowing the cover to securely fit the wellhead. This provides coverage for deep wells on roads and in homes, as well as some escape routes, preventing people or objects from falling. Manually pulling the cover and applying an initial force disrupts the balance between the cover and the weight rod, causing it to move downward. When the cover is opened to 90°, the weight of the weight rod balances the two, maintaining the wellhead's open position. Workers can now work inside the wellhead, simplifying operation and saving time and effort. The design of the slideway, pulley, first connecting rod and second connecting rod has the advantages of simple structure and small size, which reduces the space occupied at the wellhead.

[0038] Combine Figures 1 to 6As shown, an embodiment of the present disclosure provides a manhole cover with a connecting rod and a weight, which is applied to a wellhead 1 and includes a frame 2, a cover plate 3, a slide 4, a pulley 5, a first connecting rod 6, a second connecting rod 7 and a weight rod 8. The frame 2 is connected to the ground at the wellhead 1 along the width direction of the wellhead 1. The cover plate 3 is rotatably connected to the frame 2 and is used to open or close the wellhead 1. The slide 4 is connected to the inner wall of the wellhead 1 along the length direction of the wellhead 1. The pulley 5 is slidably installed in the slide 4. One end of the first connecting rod 6 is rotatably connected to the pulley 5, and the other end of the first connecting rod 6 is rotatably connected to the cover plate 3. One end of the second connecting rod 7 is rotatably connected to the pulley 5. The weight rod 8 is rotatably connected to the other end of the second connecting rod 7, and one end of the weight rod 8 is rotatably connected to the inner wall of the wellhead 1. When the wellhead 1 is in an open or closed state, the cover plate 3 and the weight rod 8 are in a state of gravity balance.

[0039] The disclosed embodiments provide a manhole cover with a connecting rod and a weight, which is applied to a manhole 1 and includes a frame 2, a cover plate 3, a slide 4, a pulley 5, a first connecting rod 6, a second connecting rod 7, and a weight rod 8. The frame 2 is connected to the ground at the manhole 1 along the width of the manhole 1 and is used to support the rotatable cover plate 3. The cover plate 3 is rotatably connected to the frame 2 and is used to open or close the manhole 1 to provide a cover. Along the length of the manhole 1, the slide 4 is connected to the inner wall of the manhole 1 and is used to support the slidable pulley 5. The pulley 5 is slidably mounted within the slide 4 and can move along the extension direction of the slide 4. One end of the first connecting rod 6 is rotatably connected to the pulley 5 and the other end is rotatably connected to the cover plate 3, allowing the cover plate 3 and the pulley 5 to move in coordination. The second connecting rod 7 is rotatably connected to the pulley 5 at one end and the other end is rotatably connected to the weight rod 8, allowing the weight rod 8 and the pulley 5 to move in coordination. One end of the weight rod 8 is rotatably connected to the inner wall of the wellhead 1 for providing weight.

[0040] During use, rotating the cover plate 3 causes the first connecting rod 6 to pull or push the pulley 5 along the extension direction of the slideway 4. This in turn drives the second connecting rod 7, pulling or pushing the weight rod 8 to rotate, causing the weight rod 8 to rotate in conjunction with the cover plate 3. This ensures that when the wellhead 1 is open or closed, the cover plate 3 and the weight rod 8 are in a state of gravitational equilibrium. When the wellhead 1 is closed, the cover plate 3 and the weight rod 8 are in a state of gravitational equilibrium, allowing the cover plate 3 to securely fit the wellhead 1. This provides coverage for deep wells on roads and in homes, as well as some escape routes, preventing people or objects from falling. Pulling the cover plate 3 manually and applying an initial force can disrupt the balance between the cover plate 3 and the weight rod 8, causing the weight rod 8 to move downward. When the cover is opened to 90°, the weight of the weight rod 8 balances the two, and the wellhead 1 remains open. At this point, workers can begin working inside the entrance, simplifying the operation and saving time and effort. Furthermore, the design of the slideway 4 , the pulley 5 , the first connecting rod 6 and the second connecting rod 7 has the advantages of simple structure and small size, thereby reducing the space occupied at the wellhead 1 .

[0041] Optionally, combined Figure 1 、 Figure 5 and Figure 6 As shown, it also includes a counterweight 9. The counterweight 9 is connected to the other end of the weight rod 8.

[0042] In the embodiment of the present disclosure, a counterweight 9 is further included that is connected to the other end of the weight rod 8. The counterweight 9 is used to act as a counterweight. During use, the counterweight 9 of different weights can be changed to adapt to cover plates 3 of different weights.

[0043] Optionally, combined Figures 1 to 6 As shown, the hinge seat 10 is further included. The hinge seat 10 is connected to the cover plate 3, and the other end of the first connecting rod 6 is rotatably connected to the hinge seat 10.

[0044] In the embodiment of the present disclosure, a hinge seat 10 is further included which is connected to the cover plate 3. The other end of the first connecting rod 6 is rotatably connected to the hinge seat 10 so that the first connecting rod 6 can rotate relative to the cover plate 3.

[0045] Optionally, combined Figures 1 to 6 As shown, the first connecting rod 6 and the hinge seat 10 also include a first pin.

[0046] In the embodiment of the present disclosure, a first pin is further included which is installed at the connection between the first connecting rod 6 and the hinge seat 10. The first pin is used to enable the first connecting rod 6 and the hinge seat 10 to rotate relative to each other to form a hinge connection.

[0047] Optionally, combined Figure 1 、 Figure 2 、 Figure 4 and Figure 6 As shown, the second pin is also included. The second pin is installed at the connection between the pulley 5 and the first connecting rod 6 and the second connecting rod 7.

[0048] In the embodiment of the present disclosure, a second pin is further included, which is installed at the connection between the pulley 5 and the first connecting rod 6 and the second connecting rod 7. The pin is used to enable the pulley 5 and the first connecting rod 6 and the second connecting rod 7 to rotate relative to each other, forming a hinge connection.

[0049] Optionally, combined Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 and Figure 6 As shown, the third pin is also included. The third pin is installed at the connection between the second connecting rod 7 and the weight rod 8.

[0050] In the embodiment of the present disclosure, a third pin is further included which is installed at the connection between the second connecting rod 7 and the weight rod 8.

[0054] In the disclosed embodiment, frame 2 is located on either side of the wellhead 1 along its length. Cover plates 3 are rotatably connected to both frames 2. Compared to a design with a single cover plate 3, the use of two cover plates 3 reduces the weight of the single cover plate 3. This reduces the force required to open the cover plate 3, making it easier to manually open the cover plate 3.

[0055] Optionally, combined Figure 4 and Figure 6 As shown, along the width direction of the wellhead 1, the slideways 4 are located on both sides of the wellhead 1, and pulleys 5 are slidably installed in the slideways 4 on both sides.
