Description

Technical Field

[0001] The utility model relates to a maintenance device, to the construction of bridge engineering piers, and in particular to a pier coating device. Background Art

[0002] With the continuous expansion of my country's transportation network, the status of bridge engineering in transportation has become increasingly prominent. As an important part of transportation infrastructure, bridges carry the important mission of connecting cities and promoting regional development. In bridge structures, the quality of the bridge substructure directly determines the overall service life of the bridge and driving safety. In pier construction, coating curing is one of the important means to ensure the quality of pier construction.

[0003] In the concrete curing process, plastic film plays a vital role. Plastic film can effectively prevent the rapid evaporation of water on the concrete surface, thereby ensuring that the concrete has enough water to participate in the hydration reaction during the hardening process. This helps to extend the hardening period of concrete and ensure the quality of concrete. In the prior art, it is installed by crane and manually wound by workers, which has low curing efficiency, high construction cost, high safety risk and high labor intensity.

Although the above device can reduce labor when coating the pier, and the coating is performed by the coating device, its device structure is complex and difficult for workers to assemble. Summary of the invention

[0009] Preferably, the width of the annular guide groove is smaller than the diameter of the ball.

[0010] Preferably, the width of the annular guide groove is greater than the width of the connecting end between the ball and the hook.

[0011] Preferably, an upper limiter and a lower limiter are respectively provided at both ends of the film reel, and the diameters of the upper limiter and the lower limiter match the initial diameter of the film on the film reel.

[0012] Preferably, a connecting hole through which the traction line passes is provided at the center of the film reel, and the traction line is fixed to a connecting piece provided at the center of the lower limiter.

[0013] Preferably, the annular lifting ring is provided with a plurality of fixing holes, and the annular lifting ring is fixed to a plurality of pier column steel bars provided on the pier column by a plurality of tying wires passing through the plurality of fixing holes.

[0015] Preferably, the hook and the ball are an integrally formed structure.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] A pier column film covering device includes an annular lifting ring, a traction line, a film reel and a traction device; the annular lifting ring is assembled on the top of the pier column and stably fixed on the pier column, so as to ensure that the subsequent film covering operation can be carried out smoothly; the traction device is slidably connected with the annular guide groove opened at the bottom of the annular lifting ring, and the traction device moves freely around the pier column, so as to achieve uniform coverage of the film. The annular guide groove ensures the stability of the movement of the traction device and avoids possible deviation or misalignment during the film covering process; the film reel is connected to the traction device through the traction line, and when the traction device moves in the annular guide groove, it drives the film reel connected to the traction line to move, so as to achieve film covering of the pier column; the operation is convenient, the construction cost is low, and the pier column can be quickly covered with film, thereby improving work efficiency.

[0018] Furthermore, the hook is fixedly mounted on the ball bearing, which ensures the stability of the hook during the laminating process and prevents it from shaking or falling off during the traction process. The design of the ball bearing enables the traction device to slide smoothly in the annular guide groove, reducing friction and resistance and improving the laminating efficiency.

[0019] Furthermore, the inner cavity provided inside the annular lifting ring is specifically used to accommodate the ball, and the arc-shaped contact surface of the inner cavity matches the shape of the ball. This design can ensure that the ball can roll smoothly in the inner cavity and reduce friction and resistance. The design of the inner cavity makes the entire traction device structure more compact, reduces space occupancy, and makes the installation of the device on the pier more convenient.

[0020] Furthermore, the groove width is smaller than the ball diameter, which effectively prevents the risk of the ball accidentally falling off in the guide groove. When the traction device is working, even if it encounters bumps or vibrations, the ball can be firmly kept in the guide groove, ensuring the continuity and safety of the entire laminating process.

[0021] Furthermore, since the width of the annular guide groove is greater than the width of the connection end between the ball and the hook, it is ensured that when the traction device moves in the annular guide groove, the connection end between the ball and the hook can smoothly pass through the guide groove without being blocked or stuck. This ensures smooth laminating operation and avoids interruption of operation or laminating failure caused by device jamming.

[0022] Furthermore, the upper and lower stoppers are set to effectively control the position of the film on the reel. When the film is continuously pulled out for lamination, the lower stopper ensures that the film will not be too loose or slip off the reel, thereby avoiding damage or confusion of the film. At the same time, the upper stopper prevents the film from being over-tightened or broken, ensuring the continuity of the lamination process.

[0023] Furthermore, through the connection hole in the center of the film reel, the traction wire can stably pass through and connect to the film reel. The traction wire is fixed to the connecting piece in the center of the lower stopper. This design forms a close linkage relationship between the film reel and the lower stopper. When the traction wire pulls the film reel to release the film, the lower stopper will move accordingly to ensure that the position of the film on the reel is accurately controlled.

[0024] Furthermore, the arrangement of multiple fixing holes and wire ties enables multi-point fixation between the annular lifting ring and the pier column reinforcement. This multi-point fixation method significantly enhances the stability of the entire device, ensuring that the device is not prone to shaking or falling off during the film coating process, thereby ensuring the quality and efficiency of the film coating. The wire ties can easily pass through the fixing holes and be fixed to the pier column reinforcement, and can also be quickly removed when needed. This improves construction efficiency and reduces unnecessary maintenance costs.

[0025] Furthermore, the fixing holes are symmetrically arranged on both sides of the annular lifting ring. This symmetry ensures that the device can evenly distribute the load when subjected to force, thereby reducing shaking or distortion caused by uneven force.

[0026] Furthermore, the one-piece structure means that there are no connectors or joints between the hook and the ball as in traditional designs, eliminating the safety hazards caused by loose or broken connections. This design significantly improves the overall stability of the structure, making the device more reliable during operation and reducing the risk of failure and damage.

[0035] The following is an explanation and description of the technical scheme of the embodiment of the utility model in conjunction with the drawings of the embodiment of the utility model, but the following embodiment is only a preferred embodiment of the utility model, not all. Based on the embodiment in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the utility model.

[0036] In the following description, terms such as "inside", "outside", "up", "down", "left", "right", etc. that indicate directions or positional relationships are only used to facilitate the description of the embodiments and simplify the description, and do not indicate or imply that the referred device or element must have a specific direction, be constructed and operated in a specific direction. Therefore, it should not be understood as a limitation on the present invention.

[0037] like Figures 1 to 4As shown, a pier column film covering device includes a ring hanging ring 1, a traction line 2, a film reel 3 and a traction device 4; the ring hanging ring 1 is provided with a plurality of fixing holes 1-2, and the ring hanging ring 1 is fixed to a plurality of pier column steel bars 5-1 provided on the pier column 5 by a plurality of tying wires passing through the plurality of fixing holes 1-2. The ring hanging ring 1 is fixed to the top of the pier column 5, and the ring hanging ring 1 bears various forces and pressures during the film covering process. The ring hanging ring 1 is fixed to the pier column steel bars 5-1 by tying wires or other fixings, thereby improving the stability of the entire device.

[0038] A plurality of fixing holes 1-2 are symmetrically arranged on both sides of the annular lifting ring 1 with the annular guide groove 1-1 as the central axis. The symmetrical fixing hole design makes the installation process more convenient. The operator can clearly identify the position of the fixing hole 1-2 and quickly and accurately complete the wire threading and fixing work. The symmetry ensures that the device can evenly distribute the load when subjected to force, reducing shaking or distortion caused by uneven force. The stability of the device is further improved.

[0039] Among them, the traction device 4 is slidably connected with the annular guide groove 1-1 opened at the bottom of the annular hanging ring 1, ensuring the stable movement of the traction device 4 on the annular hanging ring 1, thereby realizing uniform and continuous traction of the film; the traction device 4 includes a hook 4-1 and a ball 4-2, the hook 4-1 is fixedly assembled on the ball 4-2, the hook 4-1 is used to fix and pull the film reel 3, and the ball 4-2 enables the traction device 4 to slide smoothly in the annular guide groove 1-1; the annular hanging ring 1 is provided with an inner cavity for accommodating the ball 4-2, the contact surface between the inner cavity and the ball 4-2 is an arc surface, which provides space for the ball to move, and also ensures the stability and smoothness of the ball during movement through the contact between the arc surface of the inner cavity and the ball. This arc-shaped contact surface reduces friction, allowing the ball to roll smoothly in the inner cavity, thereby ensuring smooth movement of the traction device; the hook 4-1 and the ball 4-2 are an integrated structure, which enhances the stability of the traction device 4, avoids failures caused by loose or broken connecting parts, and improves the service life and reliability of the device. At the same time, the integrated structure also simplifies the manufacturing process and reduces the manufacturing cost.

[0040] Furthermore, the groove width of the annular guide groove 1-1 is greater than the width of the connection end of the ball 4-2 and the hook 4-1, and the upper limiter 3-1 and the lower limiter 3-2 are respectively provided at both ends of the film reel 3, and the diameters of the upper limiter 3-1 and the lower limiter 3-2 match the initial diameter of the film on the film reel 3. This ensures the smooth movement of the traction device 4 in the annular guide groove 1-1, and reduces the jamming or friction problems caused by size mismatch. This design not only improves the working efficiency of the device, but also prolongs its service life.

[0041] The film reel 3 is connected to the traction device 4 through the traction line 2. The center of the film reel 3 is provided with a connection hole 3-3 through which the traction line 2 passes. The traction line 2 is fixed to a connection piece 3-2-1 provided at the center of the lower stopper 3-2. This ensures that the traction line can smoothly pass through the reel and connect to the traction device. This design avoids the slippage or misalignment of the traction line on the reel, and ensures the stability and reliability of the traction line 2.

[0042] During the implementation process, the annular lifting ring 1 is first assembled on the top of the pier 5, and then the traction device 4 and the film reel 3 on the annular lifting ring 1 are connected through the traction line 2. One end of the traction line 2 is fixed to the connecting piece 3-2-1 provided in the center of the lower limiter 3-2, and the other end of the traction line 2 passes through the hook 4-1 and is controlled by the operator, so that the height of the film reel 3 can be adjusted by pulling the traction line 2. The operator only needs to rotate around the pier 5 through the traction line 2 under the pier 5, which has high construction efficiency, reduces the use time of crane equipment, and reduces cost expenditure.
