Description

Technical Field

[0001] The utility model relates to a pier column operating platform and belongs to the technical field of pier column construction. Background Art

[0002] In the construction of large bridges, the maintenance of piers and the installation of cap beam hoops are key steps to ensure the stability and safety of the overall structure. As the main load-bearing structure, the maintenance of piers includes regular inspections, repairing surface cracks, applying waterproof and anti-corrosion coatings, etc. to prevent damage caused by environmental factors and structural loads. In addition, the cap beam is an important component connecting the piers to the superstructure, and the hoops installed on it are used to enhance the lateral support of the piers and improve their bending and shear resistance. The correct installation of the hoops not only helps to disperse the load, but also protects the piers from serious damage in extreme situations such as earthquakes. Therefore, the precise maintenance of piers and the professional installation of cap beam hoops are the cornerstones for ensuring the long-term operation and safety of bridges.

[0003] In the Chinese patent application number 202311294951.X, a self-lifting pier column work platform is disclosed. By surrounding the pier column with a circular work platform and using a hand-pulled chain hoist and other suspension devices to adjust the height of the work platform, construction workers can conveniently perform outer wrapping maintenance, surface modification, and installation of cap beam hoops at various heights. This method not only improves the efficiency and safety of construction, but also greatly reduces the manpower and material costs during the construction process.

[0004] However, this solution still has certain problems. Since this solution only fixes the cross-shaped load-bearing beam in the steel bars reserved at the top of the pier, it may not be strong enough and easy to shake, which may pose a hidden danger to construction safety, especially when subjected to large external forces (such as strong winds). The stability of the working platform is crucial. Utility Model Content

[0005] The utility model aims to provide a pier column working platform which can be stably connected so as to ensure construction safety and improve working efficiency.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a pier column working platform, comprising

[0007] A support frame is arranged on the top of the pier column and protrudes from the side of the pier column;

[0008] A platform is arranged along the circumference of the pier column, suspended below the support frame, and can move up and down along the axis of the pier column; and

[0009] The sleeve is arranged along the circumference of the pier column and connected to the support frame, and the inner wall of the sleeve abuts against the side surface of the pier column.

[0010] Furthermore, the sleeve is connected to the support frame via a connecting column, and the length of the connecting column is within a first preset range.

[0011] Furthermore, the sleeve has a preset height and the top is welded to the support frame.

[0012] Furthermore, the support frame is cross-shaped.

[0013] Furthermore, the support frame includes two I-beams perpendicular to each other, and both ends of the I-beams are provided with lifting holes.

[0014] Furthermore, the support frame is connected to the platform via an electric hoist.

[0015] Furthermore, a guardrail is arranged on the outer edge of the platform.

[0016] Furthermore, the platform is hexagonal.

[0017] Furthermore, a buffer is provided below the platform.

[0018] Furthermore, a slide rail is provided on the bottom surface of the sleeve, a hook is slidably provided on the slide rail, and the hook can rotate along the circumference of the pier column.

[0019] The beneficial effect of the utility model is that the sleeve is arranged along the circumference of the pier and connected to the support frame, and the inner wall of the sleeve fits tightly against the side of the pier, thereby strengthening the connection between the support frame and the pier, which not only greatly enhances the stability of the platform and avoids shaking and displacement during operation, but also simplifies the installation process and improves construction efficiency by further stabilizing the connection through the sleeve.

[0025] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0027] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0029] First, see Figure 1 It should be noted that a steel bar 201 protruding from the top of the pier 200 is reserved on the top of the pier 200 , and the steel bar 201 can limit the pier work platform 100 , so that the pier work platform 100 can be installed on the top of the pier 200 .

[0030] Example 1

[0031] See also Figure 2 and Figure 3 A pier work platform 100 shown in a preferred embodiment of the present application includes a support frame 1, a platform 2 and a sleeve 3.

[0032] The support frame 1 is arranged on the top of the pier 200 and protrudes from the side of the pier 200. The support frame 1 is inserted into the gap between the steel bars 201, thereby achieving preliminary position limiting and fixing.

[0033] In this embodiment, the support frame 1 is cross-shaped and includes two mutually perpendicular I-beams, which not only enhances the stability and load-bearing capacity of the support frame 1, but also enables the support frame 1 to better disperse and bear the weight and dynamic load from the platform 2 and the construction personnel. Optionally, in order to further enhance the load-bearing capacity of the support frame 1, the number of I-beams can also be increased to improve the stability of the platform 2 when it is suspended, but it is necessary to ensure that the I-beams are symmetrically arranged on the top of the pier 200 to evenly disperse the force. In order to facilitate the installation and disassembly of the platform 2, hoisting holes are also opened at both ends of the I-beam for hoisting the platform 2.

[0034] The platform 2 is arranged along the circumference of the pier 200, suspended below the support frame 1, and can move up and down along the axis direction of the pier 200. In this embodiment, the support frame 1 and the platform 2 are connected by an electric hoist 4, and there are four electric hoists 4. One end of the electric hoist 4 is connected to the lifting hole, and the other end is connected to the platform 2. Through the electric hoist 4, the construction personnel can be quickly sent to the designated location. Optionally, the support frame 1 and the platform 2 can also be connected by a hand hoist, which is a prior art and will not be described in detail here.

[0035] In order to further improve the safety and practicality of the pier work platform 100, a guardrail 21 is provided on the outer edge of the platform 2, thereby providing additional protection for the construction workers to prevent them from slipping or other accidents during high-altitude operations, thereby ensuring personal safety during the construction process. In addition, the provision of the guardrail 21 also helps to limit the working area, prevent accidental falling of construction materials or tools, and thus reduce the safety risks of pedestrians or other workers on the ground.

[0036] In order to better adapt to the spatial structure around the pier 200 and maximize the use of the working area, the platform 2 is hexagonal. In this way, not only the working space is optimized, so that construction personnel can perform various operations more flexibly, but also the stability and load distribution capacity of the platform 2 are improved, ensuring the safety and efficiency of the operation process. Optionally, the platform 2 can also be circular, which can also evenly disperse the force, but making the platform 2 circular requires a more sophisticated manufacturing process. In addition, since the platform 2 is circular, it is more likely to rotate when the platform 2 contacts the pier 200, thereby creating a safety hazard.

[0037] A buffer (not shown) is provided below the platform 2. When the platform 2 shakes, the buffer can contact the pier 200, thereby effectively absorbing the vibration and impact caused by hoisting, movement or external environmental factors (such as wind force), reducing the impact of these factors on the operation of construction personnel, and also protecting the surface of the platform 2 and the pier 200 from damage. The specific structure of the buffer is relatively common in the prior art and will not be described in detail here.

[0038] The sleeve 3 is arranged along the circumference of the pier column, connected to the support frame 1, and the inner wall of the sleeve 3 abuts against the side of the pier column 200. The inner wall of the sleeve 3 abuts against the side of the pier column 200, thereby limiting and reinforcing the connection between the support frame 1 and the platform 2. The sleeve 3 can apply a certain degree of pressure to the pier column 200 when necessary to limit the left and right shaking of the platform 2, thereby ensuring that the platform 2 can remain stable under various environmental conditions, including strong winds or other unstable factors, thereby enhancing the stability of the platform 2 and providing a safer and more stable working environment for construction personnel.

[0039] In this embodiment, the sleeve 3 is hoisted below the support frame 1 through four connecting columns 31, and the two ends of the connecting columns 31 are respectively welded to the sleeve 3 and the support frame 1, thereby achieving further position fixing of the support frame 1. The length of the connecting column 31 is within the first preset range, so that the sleeve 3 has a preset height, so that it can avoid the waste of materials due to the length of the connecting column 31 being too long, and it can also avoid the poor effect of preventing shaking due to the length of the connecting column 31 being too short. Among them, the first preset range can be obtained according to the experience of the construction personnel.

[0040] Example 2

[0041] See also Figure 4 The structure of the pier work platform 100 shown in this embodiment 2 is roughly the same as that of the pier work platform 100 in the embodiment, with the difference being that a slide rail 32 is provided on the bottom surface of the sleeve 3, a hook 33 is slidably provided on the slide rail 32, and the hook 33 can rotate along the circumference of the pier 200.

[0042] Specifically, a slide rail surrounding the pier 200 is provided on the lower surface of the sleeve 3, and the hook 33 can rotate around the pier 200 through the slide rail 32. The construction personnel can hang the tool bag they carry on the hook 33 through a hanging chain (not shown). In this way, when performing a circumferential inspection or operation on the side of the pier 200, the construction personnel can simply pull the hanging chain to make the tool bag move with the rotation of the tool bag, without the need to hold heavy objects, which not only reduces the burden on the body, but also avoids the danger that may occur in high-altitude operations. The configuration of the slide rail 32 and the hook 33 not only provides a convenient way to carry the tool bag, but also provides the possibility of hanging other necessary equipment such as construction lamps and safety ropes, and the scope of use can be further expanded by setting multiple hooks 33. When the construction personnel move along the circumference of the pier 200, the hanging items can be easily followed, ensuring the cleanliness and safety of the construction site, and also ensuring that the construction personnel can obtain the required tools or equipment anytime and anywhere.

[0043] It should be noted that when the height of the pier 200 is too high, the length of the suspension chain will be too long, so it may also shake, causing hidden dangers. Therefore, the pier work platform 100 shown in Example 2 is generally suitable for piers 200 with a height of ten to twenty meters.

[0044] In the present application, the sleeve 3 is arranged along the circumference of the pier 200 and connected to the support frame 1. The inner wall of the sleeve 3 fits tightly against the side of the pier 200, thereby strengthening the connection between the support frame 1 and the pier 200. This not only greatly enhances the stability of the platform 2 and avoids shaking and displacement during operation, but also further stabilizes the connection through the sleeve 3, simplifies the installation process, and improves construction efficiency.

[0045] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0046] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
