Description

Technical Field

[0001] The utility model relates to the technical field of pipeline maintenance, in particular to an auxiliary device for replacing a nameplate. Background Art

[0002] The test pile can be used to detect cathodic protection parameters. It is installed on the ground above the pipeline and is an indispensable device in pipeline management and maintenance. The test pile mainly includes a pile body, a test terminal block, a test wire and a nameplate, among which the nameplate of the test pile needs to be replaced regularly.

[0003] At present, nameplate replacement operations generally use manual direct replacement or ladder-assisted replacement methods. However, since the nameplate of the test pile is usually installed on the top of the test pile at a high height from the ground, the manual direct replacement method requires multiple people to work together, and the operator needs to keep the electric drill in a raised position to disassemble and install the fixing screws on the nameplate. On the one hand, the operator needs to keep his arms raised for a long time, resulting in high labor intensity for the operator; on the other hand, the operator needs to keep applying horizontal force to the electric drill while raising the electric drill so that the electric drill can smoothly disassemble and install the fixing screws of the nameplate, resulting in high difficulty and low efficiency in this operation method. When the ladder-assisted replacement method is used, due to the complex terrain along the pipeline, some ground conditions are not suitable for placing ladders, and the operator needs to climb up and down the ladder, resulting in low efficiency in the nameplate replacement operation.

[0004] Therefore, how to reduce the workload of test pile nameplate replacement operations and improve work efficiency has become a technical problem that needs to be solved urgently. Utility Model Content

[0005] The purpose of the utility model is to overcome the problems of high work intensity and low work efficiency in the test pile nameplate replacement operation in the prior art, and to provide an auxiliary device for replacing nameplates and nameplate replacement equipment, wherein the auxiliary device can improve the work efficiency of disassembling and assembling high-place nameplates and reduce the work intensity of replacement.

[0007] Through the above technical solution, the moving rod can slide along the sliding groove close to or away from the first fixed rod. When replacing the nameplate, the moving rod is slid and abutted against the end of the replacement tool (such as an electric drill) away from the nameplate, so that the moving rod applies a force to the electric drill in the horizontal direction and toward the nameplate, thereby fixing the electric drill between the nameplate and the moving rod, which is convenient for the electric drill to remove and install the fixing screws on the nameplate. In addition, when replacing the nameplate, the side of the first fixed rod close to the moving rod abuts against the opposite surface of the installation nameplate of the test pile, so that the auxiliary device provided by the utility model can better maintain stability during the process of replacing the nameplate.

[0008] Optionally, the auxiliary device provided by the utility model further includes a driving unit for driving the moving rod to slide.

[0009] Optionally, the driving unit comprises a traction rope, one end of which is connected to the first fixed rod and extends around the moving rod, so as to be able to apply a force to the moving rod toward the first fixed rod by pulling the traction rope at a position lower than the nameplate.

[0026] The auxiliary device for replacing a nameplate and the nameplate replacing equipment disclosed in the present utility model are described below with reference to the accompanying drawings.

[0027] The first aspect of the utility model provides an auxiliary device for replacing a nameplate, referring to Figure 1-Figure 3As shown, the auxiliary device includes: a first fixed rod 2, a second fixed rod 3 and a moving rod 1, wherein the number of the second fixed rods 3 is two, the two second fixed rods 3 are arranged parallel to each other and are respectively connected to the first fixed rod 2, a sliding groove 31 is formed in the second fixed rod 3, and the moving rod 1 is slidably connected to the sliding groove 31 and can slide along the sliding groove 31 to approach or move away from the first fixed rod 2. Figure 1 and Figure 2 As shown, the moving rod 1, the first fixed rod 2 and the two second fixed rods 3 can form a square shape, and by sliding the moving rod 1 toward the first fixed rod 2, a force is applied to the moving rod 1 toward the first fixed rod 2 to push the replacement tool for replacing the nameplate toward the first fixed rod 2.

[0028] Through the above technical solution, the moving rod can slide along the sliding groove close to or away from the first fixed rod. When replacing the nameplate, the moving rod is slid and abutted against the end of the replacement tool (such as an electric drill) away from the nameplate, so that the moving rod applies a force to the electric drill in the horizontal direction and toward the nameplate, thereby fixing the electric drill between the nameplate and the moving rod, which is convenient for the electric drill to remove and install the fixing screws on the nameplate. In addition, when replacing the nameplate, the side of the first fixed rod close to the moving rod abuts against the opposite surface of the installation nameplate of the test pile, so that the auxiliary device provided by the utility model can better maintain stability during the process of replacing the nameplate.

[0029] Optionally, the auxiliary device provided by the utility model may further include a driving unit for driving the moving rod 1 to slide.

[0030] Optionally, the driving unit can be a spring. By arranging the spring between the first fixed rod 2 and the movable rod 1, the elastic potential energy of the spring is used to drive the movable rod 1 to slide along the sliding groove 31. By driving the movable rod 1 to slide by the spring, no additional driving force is required, and the nameplate replacement can be completed by only one operator; or, the spring can be arranged between the movable rod 1 and the third fixed rod 4 described below, and the elastic potential energy of the spring is used to drive the movable rod 1 to slide along the sliding groove 31.

[0031] Optionally, refer to Figure 2 As shown, the driving unit includes a traction rope 5, one end of which is connected to the first fixed rod 2 and extends around the mobile rod 1, so that the traction rope 5 can be pulled at a position below the nameplate to apply a force to the mobile rod 1 toward the first fixed rod 2. Figure 2As shown, one end of the traction rope 5 is connected to the first fixed rod 2, and the other end passes around the moving rod 1 and extends toward a position below the nameplate and close to the first fixed rod 2. Therefore, on the one hand, the operator can pull the traction rope 5 at a position below the nameplate to drive the moving rod 1 to slide without having to keep the arm raised for a long time, thereby reducing the labor intensity of replacing the nameplate and improving the efficiency of the replacement work; on the other hand, by pulling the other end of the traction rope 5, the operator can apply a stable force F to the moving rod 1, thereby allowing the moving rod 1 to slide stably.

[0032] Furthermore, the number of the traction ropes 5 can be multiple, for example, Figure 2 As described, there are two traction ropes 5, one end of the two traction ropes 5 is respectively connected to the two ends of the first fixed rod 2, and the other ends extend in a direction parallel to the second fixed rod 3. After bypassing the moving rod 1, the other ends of the two traction ropes 5 continue to extend in parallel with each other toward a position below the nameplate and close to the first fixed rod 2. By setting two traction ropes 5, the sliding stability of the moving rod 1 can be further improved.

[0033] Optionally, refer to Figure 2 As shown, the drive unit also includes a handle 6 connected to the other end of the traction rope 5. The handle 6 can facilitate the operator to pull the traction rope 5. Figure 2 As shown, the other ends of the two traction ropes 5 are respectively connected to the two ends of the handle 6, so that the operator can operate the handle 6 and pull the traction rope 5 conveniently.

[0034] Optionally, the drive unit further includes a rubber sleeve sleeved on the handle 6 , thereby increasing the comfort of the operator holding the handle 6 .

[0035] Optionally, refer to Figure 3 As shown, according to an embodiment of the auxiliary device provided by the utility model, the auxiliary device also includes a stopper 7 arranged on the end of the moving rod 1, and the height of the stopper 7 is greater than the opening width of the sliding groove 31 to prevent the moving rod 1 from falling out of the sliding groove 31. Specifically, the second fixed rod 3 is a hollow rod, that is, the second fixed rod 3 has a cavity inside, and the sliding groove 31 is formed by opening the side of the second fixed rod 3 close to the moving rod 1, wherein the height of the cavity is greater than the width of the opening, and both ends of the moving rod 1 can extend into the cavity. Figure 3 As shown, the limit member 7 can be arranged in the sliding groove 31, that is, in the cavity. The height of the limit member 7 is less than the height of the cavity and greater than the width of the opening, so that the limit member can slide in the sliding groove 31 with the moving rod 1 and prevent the moving rod 1 from falling off from the sliding groove 31.

[0036] Of course, the limit member 7 can also be arranged outside the sliding groove 31. For example, openings are made on both sides of the second fixed rod 3 close to and away from the moving rod 1 to form the sliding groove 31. The moving rod 1 passes through the two openings and penetrates the second fixed rod 3. The limit member 7 is connected to the moving rod 1 and is arranged on the side of the second fixed rod 3 away from the moving rod 1. The height of the limit member 7 is greater than the width of the above-mentioned opening, thereby preventing the moving rod 1 from falling off the sliding groove 31.

[0037] Optionally, refer to Figure 1 and Figure 2 As shown, the auxiliary device provided by the utility model further includes a third fixing rod 4 whose two ends are respectively vertically connected to the other ends of the two second fixing rods 3. When replacing the nameplate, the operator can fix the auxiliary device to the installation height of the nameplate by holding the third fixing rod 4, and the operator can apply a force away from the nameplate to the third fixing rod 4, so that the first fixing rod 2 can be more stably abutted against the opposite surface of the test pile installation nameplate, which is conducive to the replacement of the nameplate.

[0038] Optionally, the first fixing rod 2 , the second fixing rod 3 and the third fixing rod 4 are square rods to facilitate fixing the auxiliary device to the installation height of the nameplate, and the moving rod 1 is a cylindrical rod to facilitate sliding of the moving rod 1 along the sliding groove 31 .

[0039] The second aspect of the utility model provides a nameplate replacement device, comprising an electric drill and the above-mentioned auxiliary device for replacing the nameplate, wherein the moving rod 1 can abut against an end of the electric drill away from the drill bit of the electric drill.
