Description

Technical Field

[0001] The utility model relates to the technical field of construction equipment, in particular to a hanging basket cantilever casting beam end operating platform device. Background Art

[0002] As a key equipment, the hanging basket plays a core role in the cantilever continuous beam concrete pouring construction. Its structure is complex and precise, and is integrated with multiple parts such as truss system, suspension system, anchoring system, walking system, working platform and formwork system. The hanging basket can move along the pre-laid track, like a movable formwork, and can be firmly suspended on the completed cantilever beam section to realize the section-by-section construction of the next beam section, and through cyclic operation until the entire cantilever beam section is poured.

[0003] In this process, the hanging basket cantilever casting beam end operating platform device is an important component of the hanging basket working platform, and it is also an area where construction safety risks are concentrated. At present, for the cantilever beam section prestressing project constructed by hanging basket, the common practice is to temporarily build a scaffolding above the front bottom formwork of the beam end and supplement it with a wooden springboard as an operating platform for construction workers. However, this traditional construction method has significant disadvantages: after completing the longitudinal prestressing project of a cantilever beam section, the operating platform must be dismantled first, and then the hanging basket must be pushed to the next beam section for reinforced concrete structure construction; after this stage is completed, the same type of operating platform must be re-erected to continue the prestressing project.

[0004] The repeated construction and dismantling of the operating platform process leads to problems such as slow construction speed, low efficiency, and high labor costs. At the same time, the stability of the frequently constructed scaffolding is difficult to ensure and is prone to instability, greatly increasing the safety hazards at the construction site.

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0024] In the description of the embodiments of the present utility model, it should be noted that the terms "center", "longitudinal", "lateral", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the embodiments of the present utility model 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 a limitation on the embodiments of the present utility model. In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. It should also be noted that in the description of the present utility model, unless otherwise clearly specified and limited, the terms "set", "install", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.

[0025] The utility model is used to solve the safety and efficiency problems in the longitudinal prestressing engineering stage in the construction of cantilever continuous beams. When the concrete strength of the beam section completed by the hanging basket reaches the standard, the construction personnel need to carry out a series of complex processes such as installation and positioning of steel strands, anchor fixing, tensioning and pipe grouting, etc., which require extremely high safety and stability of the operating platform. The existing technology adopts the method of temporarily building scaffolding and wooden springboards, which has safety hazards and low efficiency. To this end, the utility model proposes an efficient, safe and adaptable hanging basket cantilever casting beam end operating platform device to ensure that when the hanging basket is transferred to the next beam section for construction, it can be quickly and stably built and reused, effectively overcoming the disadvantages of slow speed, low efficiency, high labor cost and great safety hazards of traditional methods, thereby significantly improving the quality and efficiency of cantilever continuous beam prestressing engineering construction.

[0026] Combine the following Figure 1-Figure 4 The specific implementation manner of the hanging basket cantilever casting beam end operating platform device of the utility model is described.

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the utility model provides a hanging basket cantilever casting beam end operating platform device, comprising: a platform cantilever beam 110, which is arranged on the front upper cross beam 100 of the hanging basket truss system and extends horizontally to the front of the hanging basket truss system; at least two traction rods 120, the traction rods 120 vertically pass through the platform cantilever beam 110, and the traction rods 120 are provided with a first positioning member 121, and the first positioning member 121 is located above the platform cantilever beam 110, so as to limit the vertical position of the traction rod 120 relative to the platform cantilever beam 110 through the first positioning member 121; a hanging rail 130, which is arranged at the lower end of the traction rod 120; a shoulder pole beam 140, which is arranged between at least two traction rods 120, and a jack 141 facing the shoulder pole beam 140 is arranged above the platform cantilever beam 110; the vertical positions of the first positioning member 121 and the shoulder pole beam 140 relative to the traction rod 120 are adjustable.

[0028] Among them, through the lifting effect of the jack 141, the shoulder pole beam 140 can be raised relative to the platform cantilever beam 110, thereby driving the traction rod 120 and the hanging rail 130 to be lifted. At this time, the first positioning member 121 is adjusted downward to the upper surface of the platform cantilever beam 110, so that the traction rod 120 and the hanging rail 130 can maintain the lifted position, and the hanging rail 130 can be raised and adjusted. The shoulder pole beam 140 is supported by the jack 141, and the first positioning member 121 is moved away from the upper surface of the platform cantilever beam 110. At this time, the jack 141 is retracted to make the shoulder pole beam 140 descend, thereby making the traction rod 120 and the hanging rail 130 descend until the first positioning member 121 contacts the platform cantilever beam 110, and the hanging rail 130 is lowered and adjusted. After each adjustment, the vertical position of the shoulder pole beam 140 relative to the traction rod 120 can be changed, so as to continue to raise or lower the adjustment.

[0029] Specifically, the platform cantilever beam 110 is arranged at the front end of the front upper crossbeam 100 of the basket truss system and extends horizontally, providing basic support for the entire operating platform. At least two traction rods 120 vertically pass through the platform cantilever beam 110, and each traction rod 120 is provided with a first positioning member 121. By adjusting the position of the first positioning member 121 above the platform cantilever beam 110, the vertical height of the traction rod 120 can be accurately defined. The hanging rail 130 is installed at the lower end of the traction rod 120 to provide a safe working space for the staff. The shoulder pole beam 140 is located between the traction rods 120 and can be supported by the jack 141 above the platform cantilever beam 110. The jacking effect of the jack 141 can lift the shoulder pole beam 140 and the traction rod 120 and the hanging rail 130 connected thereto as a whole. When it is necessary to fix the height after lifting, it is only necessary to adjust the first positioning member 121 downward to contact the upper surface of the platform cantilever beam 110. On the contrary, if the handrail 130 needs to be lowered, the jack 141 only needs to be retracted to lower the shoulder beam 140 until the first positioning member 121 after being raised contacts the platform beam 110 again. In this way, the vertical position of the shoulder beam 140 relative to the traction rod 120 can be flexibly changed, thereby achieving the height increase or decrease adjustment of the handrail 130.

[0030] The above-mentioned hanging basket cantilever casting beam end operating platform device avoids the time consumption of frequent construction and dismantling of scaffolding and other operating platforms in traditional methods through the convenient height adjustment function, thereby significantly improving the construction speed and work efficiency, reducing the manpower cost required for manual construction and dismantling of the platform, and at the same time, because the equipment is reusable, it reduces material loss and economic cost.

[0031] like Figure 2 and Figure 3 As shown, according to a hanging basket cantilever casting beam end operating platform device provided by the utility model, the traction rod 120 vertically passes through the shoulder pole beam 140. A fastening structure for fastening the traction rod 120 may be provided on the shoulder pole beam 140, or preferably, a second positioning member 122 is provided on the traction rod 120. The vertical position of the second positioning member 122 relative to the traction rod 120 is adjustable, and is located above the shoulder pole beam 140, so as to limit the highest position of the shoulder pole beam 140 relative to the traction rod 120 through the second positioning member 122. The second positioning member 122 is provided on the traction rod 120, and the vertical position of the second positioning member 122 relative to the traction rod 120 can be flexibly adjusted, and is provided above the shoulder pole beam 140. When it is necessary to limit the highest position that the shoulder pole beam 140 can reach relative to the traction rod 120, this function can be achieved by accurately adjusting the position of the second positioning member 122.

[0032] Specifically, during the lifting process of the hanging rail 130, if it is necessary to prevent the safety hazard caused by the over-lifting of the shoulder pole beam 140 or to prevent the shoulder pole beam 140 from exceeding the preset construction range, the second positioning member 122 only needs to be moved upward to an appropriate position to limit the upper limit of the height of the shoulder pole beam 140. By adding the second positioning member 122, a clear and controllable upper limit can be provided for the shoulder pole beam 140 during the lifting operation of the hanging rail 130. By effectively controlling the lifting range of the shoulder pole beam 140, it is ensured that the operating platform system can be quickly adjusted to the right position during the construction at different stages, and then efficiently cooperate with the jack 141 to realize the lifting action.

[0033] like Figure 4 As shown, according to the hanging basket cantilever casting beam end operating platform device provided by the utility model, the traction rod is finely rolled threaded steel, preferably φ25 finely rolled threaded steel. The first positioning member 121 and the second positioning member 122 each include a nut member and a gasket, and the nut member is threadedly matched with the finely rolled threaded steel.

[0034] Specifically, the nut member is connected to the finely-stretched threaded steel bar through threaded cooperation, that is, the nut member is screwed onto the finely-stretched threaded steel bar to form an adjustable fastening point. The gasket is located between the nut member and the platform cantilever beam 110 and between the nut member and the shoulder beam 140, which plays a role in increasing the friction of the contact surface, protecting the thread and fine-tuning the space size to ensure accurate and stable positioning. Through the above scheme, the height adjustment of the operating platform is more accurate and convenient. By rotating the nut member, the height position of the first positioning member 121 relative to the platform cantilever beam 110 and the highest position of the shoulder beam 140 defined by the second positioning member 122 can be flexibly adjusted, thereby achieving precise control of the height of the balustrade 130. It can be understood that, according to the different required force levels, the first positioning member 121 and the second positioning member 122 can also adopt other structural forms, such as adjustable clamps or clamps.

[0035] like Figure 2 and Figure 3 As shown, according to a hanging basket cantilever casting beam end operating platform device provided by the utility model, the hanging rail 130 includes a bottom plate 131 and a first guardrail 132 surrounding the bottom plate 131; a third positioning member 123 is provided on the traction rod 120, and the vertical position of the third positioning member 123 relative to the traction rod 120 is adjustable, and is located below the bottom plate 131, so as to limit the lowest position of the bottom plate 131 relative to the traction rod 120 through the third positioning member 123. The hanging rail 130 is mainly composed of the bottom plate 131 and the first guardrail 132 surrounding the bottom plate 131. The bottom plate 131 serves as a basic platform for workers to stand, and the first guardrail 132 plays a safety protection role in preventing people from accidentally falling.

[0036] A third positioning member 123 is provided on the traction rod 120. The third positioning member 123 and the traction rod 120 are designed to be vertically adjustable and are located below the bottom plate 131. The specific structure can be the same as the first positioning member 121 and the second positioning member 122 described above, so as to facilitate unified procurement and reduce the difficulty of maintenance. By adjusting the position of the third positioning member 123, it can be used to limit the lowest position that the bottom plate 131 can reach relative to the traction rod 120, ensuring that the bottom plate 131 can rise or fall with the traction rod 120 when performing lifting and lowering adjustments. Moreover, based on the adjustable ability of the third positioning member 123, the height position of the hanging rail 130 relative to the traction rod 120 can be adjusted, so that it is convenient for the staff to set the maximum lifting range of the hanging rail 130 according to needs.

[0037] like Figure 2 , Figure 3 As shown, according to the utility model, a hanging basket cantilever casting beam end operating platform device is provided, the upper surface of the platform cantilever beam 110 forms an operating platform; a second guardrail 111 is arranged along the edge of the operating platform. The platform cantilever beam 110 is the basic bearing component of the entire device, and its upper surface is designed as an operating platform for construction workers to operate, so that the construction workers can directly stand on the upper surface of the platform cantilever beam 110 to complete the relevant lifting and adjusting operation tasks.

[0038] In order to further ensure the safety of operation, a second guardrail 111 is provided along the edge of the operating platform (i.e., the area formed on the upper surface of the platform cantilever beam 110). The second guardrail 111 plays a role similar to a fence, surrounding the periphery of the operating platform to prevent workers from falling accidentally when performing aerial operations, thereby enhancing the safety protection effect for operators. With the first guardrail 132 located around the hanging rail 130 and the second guardrail 111 located at the edge of the operating platform formed by the platform cantilever beam 110, the utility model effectively improves the safety performance and reliability of the operating platform during the cantilever continuous beam construction process.

[0039] Furthermore, if Figure 4 As shown, according to a hanging basket cantilever casting beam end operation platform device provided by the utility model, the platform cantilever beam 110 includes a horizontal extension column 112, a platform plate 113 and a reinforcing plate 114; the platform plate 113 is arranged above the horizontal extension column 112, and a plurality of reinforcing plates 114 are respectively vertically connected between the lower surface of the platform plate 113 and the side surface of the horizontal extension column 112. Through the structural arrangement of the horizontal extension column 112, the platform plate 113 and the reinforcing plate 114, the structural design of the platform cantilever beam 110 is further optimized to enhance its bearing capacity and stability.

[0040] Specifically, the horizontal extension column 112 is the basic structural unit of the platform beam 110, which extends horizontally in a direction perpendicular to the front upper beam 100 of the basket truss system, providing a stable support foundation for the entire operating platform. The horizontal extension column 112 can be fixed to the front upper beam 100 by means such as welding, or can be bolted and fixed by a fixing structure such as bolts. A platform plate 113 is arranged above the horizontal extension column 112, and the platform plate 113 serves as an operating surface directly bearing construction personnel and related equipment, ensuring the safety and convenience of construction activities. Finally, in order to further enhance the overall strength and rigidity of the platform beam 110, a plurality of reinforcing plates 114 are arranged between the lower surface of the platform plate 113 and the side of the horizontal extension column 112, and these reinforcing plates 114 are respectively fixed to the platform plate 113 and the horizontal extension column 112 by vertical connection, thereby forming a stable three-dimensional force-bearing frame structure, which effectively prevents the platform from being deformed or damaged when bearing heavy loads or being subjected to external forces, and improves the reliability and safety of the overall structure.

[0041] like Figure 3 As shown, according to a hanging basket cantilever casting beam end operating platform device provided by the utility model, two sets of hanging basket cantilever casting beam end operating platform devices are arranged along the length direction of the front upper cross beam 100, and the two sets of hanging basket cantilever casting beam end operating platform devices share a hanging rail 130. In order to improve construction efficiency and save resources, the present embodiment adopts a parallel layout of two sets of hanging basket cantilever casting beam end operating platform devices, and the two sets of devices work together by sharing the same hanging rail 130.

[0042] Specifically, the two sets of hanging basket cantilever casting beam end operating platform devices are arranged side by side and at a certain interval along the extension direction of the front upper cross beam 100. Each set of devices includes a platform cantilever beam 110, a traction rod 120, a positioning member, and a hanging rail 130 for support and safety protection. The two sets of devices are not equipped with separate hanging rails 130, but share a hanging rail 130 as a safety enclosure facility for the staff.

[0043] In actual application, the hanging rail 130 is fixed to the lower end of the traction rod 120 of the two sets of hanging basket cantilever casting beam end operating platform devices, and acts on the two ends of the same hanging rail 130 respectively, which not only ensures that the construction personnel have sufficient working space on the hanging rail 130, but also significantly improves the carrying capacity of the hanging rail 130, thereby improving the safety and stability during the construction process.

[0044] Furthermore, on the basis that two groups of hanging basket cantilever casting beam end operating platform devices share a hanging rail 130, according to a hanging basket cantilever casting beam end operating platform device provided by the utility model, two traction rods 120 pass through the two ends of the shoulder pole beam 140 respectively; the jack 141 is located in the middle of the two traction rods 120. Each group of devices is equipped with two traction rods 120 inside, and the two traction rods 120 pass through the shoulder pole beam 140 from both ends respectively. The two traction rods 120 of each group of hanging basket cantilever casting beam end operating platform device can independently or synchronously adjust their height positions relative to the platform cantilever beam 110 and the shoulder pole beam 140 through the first positioning member 121 and the second positioning member 122 to adapt to different construction stages and working conditions.

[0045] The jack 141 is arranged in the middle of the two traction rods 120, and is located directly below the shoulder beam 140, so as to improve the force balance at both ends of the shoulder beam 140. In use, the jacks 141 of the two sets of hanging basket cantilever casting beam end operating platform devices work synchronously to synchronously control the lifting and lowering action of the hanging rail 130.

[0046] According to a hanging basket cantilever casting beam end operating platform device provided by the utility model, the horizontal projection shape of the hanging rail 130 is a rectangle; the four traction rods 120 of the two groups of hanging basket cantilever casting beam end operating platform devices are respectively close to the four corners of the hanging rail 130. The hanging rail 130 presents a rectangular structure in a horizontal projection form, so as to provide a relatively sufficient working surface and a wide operating space. In order to ensure that the hanging rail 130 has good stability and balanced force when carrying the two groups of hanging basket cantilever casting beam end operating platform devices, each group of operating platform devices is equipped with two traction rods 120, and these four traction rods 120 are respectively close to the four corners of the hanging rail 130. Among them, each traction rod 120 can directly support the hanging rail 130, so that the hanging rail 130 can maintain horizontal stability at any height state, and prevent the risk of tilting or deformation due to uneven force.

[0047] In a preferred embodiment, the front upper cross beam 100 of the hanging basket truss system is bolted to the platform cantilever beam 110 by bolts, the second guardrail 111 of the platform cantilever beam 110 is installed, the φ25 fine-rolled threaded steel bar is passed through the reserved hole of the platform cantilever beam 110, the upper end is fixed to the platform cantilever beam 110 by means of gaskets and nuts, the lower end is passed through the reserved hole of the hanging rail 130, and the hanging rail 130 is limited and fixed by means of gaskets and nuts to form a suspended operating platform.

[0048] Due to construction requirements, the platform device needs to be operated to rise to a certain height. The spiral jack 141 is raised from the minimum stroke to the maximum stroke to raise the shoulder beam 140, driving the hanging rail 130 to rise to a certain height, and then the nut on the platform cantilever beam 110 is screwed down to re-fix the φ25 finely rolled threaded steel bar on the platform cantilever beam 110, and then the spiral jack 141 returns to the minimum stroke to bring the shoulder beam 140 down a distance, and finally the nut on the shoulder beam 140 is screwed down to tighten the spiral jack 141, and the cycle is repeated until the hanging rail 130 rises to the required elevation.

[0049] Due to construction requirements, the platform device needs to be operated to a lower position. The nut on the upward rotating platform beam 110 is raised to the maximum stroke distance of the spiral jack 141, and then the spiral jack 141 is lowered from the maximum stroke to the minimum stroke to lower the shoulder beam 140, driving the hanging rail 130 to descend a certain distance, and then the nut on the shoulder beam 140 is raised to the maximum stroke distance of the spiral jack 141, and then the spiral jack 141 is raised to the maximum stroke to bring the shoulder beam 140 up a certain distance, and this cycle is repeated until the hanging rail 130 descends to the required low position.

[0050] According to the solution of the utility model, after the prestressed construction of the beam end of a cantilever beam section is completed, the operating platform device does not need to be dismantled, and the hanging basket can directly move forward with the operating platform device to the corresponding position of the beam end of the next cantilever beam section, and then adjust the height of the hanging rail 130 accordingly to facilitate the prestressed construction of the beam end of the next cantilever beam section.
