Detailed implementation manners

[0027] The following is a description of the preferred embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the present utility model, and are not intended to limit the present utility model.

[0028] As Figures 1 to 2 shown, a cement cover lifting trolley includes an arc-shaped hanger 1. One end of the arc-shaped hanger 1 is hinged with a telescopic lever assembly 2, the other end of the arc-shaped hanger 1 is provided with a boom 3, a chain 4 is connected between the arc-shaped hanger 1 and the telescopic lever assembly 2, and fixing assemblies 5 for connecting the cement cover 7 are detachably arranged on both sides of the boom 3. During the operation in the cable well, the cement cover 7 is connected through the fixing assembly 5, and the telescopic lever assembly 2 is pressed down according to the lever principle to achieve the labor-saving effect of lifting the cement cover 7, which is convenient and fast to use.

[0029] Specifically, as Figures 2 to 4 shown, the fixing assembly 5 includes a hook plate arm 501. A connecting member 502 is arranged in the middle of the hook plate arm 501. Moving blocks 503 are slidably connected to both sides of the connecting member 502. The moving blocks 503 are threadedly connected with limiting rods 504. A connecting hole 5021 is arranged at the upper end of the connecting member 502, and a locking rod 5022 is arranged at the lower end of the connecting member 502. Hook members 301 are arranged on both sides of the boom 3, and hooks 302 are connected to the lower ends of the hook members 301. The hooks 302 are inserted into the connecting holes 5021.

[0030] The cement cover plate 7 is provided with two slots 701. When connecting the cement cover plate 7, move the connecting piece 502 to separate the connecting hole 5021 from the hook 302, so as to detach the fixing component 5 from the lifting arm 3. The connecting piece 502 is fixed on the hook plate arm 501 through a fixing nut. Loosen the fixing nut, align the locking rod 5022 with the slot 701 and insert it. Then, rotate the connecting piece 502 to stagger the locking rod 5022 with the slot 701, and tighten the fixing nut to fix the position of the locking rod 5022, so that the cement cover plate 7 is fixed together with the fixing component 5. Then, move the limiting rod 504 to the side of the cement cover plate 7. When turning the limiting rod 504 to make the limiting rod 504 move downward relative to the moving block 503, the hook plate arm 501 and the connecting piece 502 will move upward relatively, and the connecting piece 502 will drive the cement cover plate 7 to move upward synchronously, so as to achieve the effect of loosening the cement cover plate 7. Finally, insert the hook 302 into the connecting hole 5021 to install the fixing component 5 on the lifting arm 3, which is convenient for the next lifting operation.

[0031] As Figure 5 shown, the hook member 301 is hollow and formed with a plug-in position 3011. An adjusting bolt 3012 is threadedly connected above the plug-in position 3011. The lifting arm 3 is plugged into the plug-in position 3011. During assembly, the lower end of the adjusting bolt 3012 abuts against the upper surface of the lifting arm 3, so as to achieve the fixing effect. When it is necessary to adjust the position of the fixing component 5, the adjusting bolt 3012 can be turned to make the lower end of the adjusting bolt 3012 move away from the lifting arm 3, so that the hook member 301 can slide horizontally relative to the lifting arm 3 to change the position of the hook member 301. After adjustment, turn the adjusting bolt 3012 again to make the lower end of the adjusting bolt 3012 abut against the lifting arm 3 again.

[0032] As Figure 6 shown, the telescopic lever assembly 2 includes a first pipe body 201. A lever 202 is sleeved inside the first pipe body 201. A handle 203 is arranged at the end of the lever 202, which is convenient for the user to press to achieve the lifting operation. The first pipe body 201 is provided with a fixing hole 2011. A fixing piece 2012 is threadedly connected to the fixing hole 2011. The end of the fixing piece 2012 abuts against the lever 202. When it is necessary to adjust the length of the telescopic lever assembly 2, the fixing piece 2012 can be turned to make the lower end of the fixing piece 2012 move away from the lever 202, so as to adjust the extending length of the lever 202. After adjustment, turn the fixing piece 2012 again to make the lower end of the fixing piece 2012 abut against the lever 202 again to achieve the fixing effect.

[0033] On the upper surface of the first pipe body 201, a U-shaped part 2013 is provided. On the upper surface of the U-shaped part 2013, a U-shaped position 2014 for accommodating the insertion of the chain 4 is provided. A spring pin 2015 is inserted at the lower end of the U-shaped part 2013. One end of the chain 4 is arranged in the middle of the arc-shaped hanger 1, and the other end of the chain 4 is arranged on the spring pin 2015. When it is necessary to adjust the angle of the telescopic lever assembly 2, the spring pin 2015 is pulled out. After setting the required angle of the telescopic lever assembly 2, the chain 4 is snapped into the U-shaped position 2014, and then the spring pin 2015 is inserted through the corresponding positions of the U-shaped part 2013 and the chain 4 to achieve fixation.

[0034] As Figure 7 shown, the second pipe body 204 into which the hook plate arm 501 can be inserted is staggeredly arranged on the first pipe body 201. Connecting shafts 101 are arranged on both sides of the lower end of the arc-shaped hanger 1. Wheels 6 are rotatably connected to the connecting shafts 101. When transferring the working location, the hook plate arm 501 can be inserted at both ends of the second pipe body 204. With the hook plate arm 501 and the boom 3 as the support points, it can temporarily act as a transportation tool to place the telescopic fence 8 on it for transportation, saving manpower during transportation.

[0035] Working principle: First, fixedly connect the fixing component 5 with the cement cover plate 7. Then, press the handle 203 to drive one end of the telescopic lever assembly 2 to move downward. At the same time, under the action of the chain 4, the arc-shaped hanger 1, the boom 3, and the fixing component 5 will move upward correspondingly, thereby driving the cement cover plate 7 to achieve the lifting operation, which is easy, labor-saving, convenient and fast. After use, by removing the spring pin 2015, the arc-shaped hanger 1 can be rotated clockwise so that the top of the arc-shaped hanger 1 contacts the telescopic lever assembly 2 to achieve the folding effect, which can greatly reduce the space volume and is convenient for transportation.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. However, any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
