Description

Technical Field

[0001] This utility model relates to the field of building technology, specifically to a hoisting platform for construction sites. Background Technology

[0002] A construction material unloading platform, also known as a hoisting platform, is installed on the middle floor of a building under construction. It is an essential piece of equipment in construction, mainly used for placing and transferring materials, including building materials such as formwork and steel bars, as well as construction tools.

[0003] When used as a platform, temporary building materials or construction tools can be placed on the platform for easy access when needed. These materials or tools are often transported to the upper level using tower cranes or overhead cranes. It can also serve as a transfer platform. After the completion of one floor's construction, materials or tools such as formwork and remaining steel bars need to be moved to the next floor or top floor, such as the top Bailey bridge of an intelligent construction platform (building machine). From there, they are moved up using overhead cranes or tower cranes. Therefore, hoisting platforms play an indispensable role in construction. However, existing hoisting platforms are often fixed in one place and cannot be raised or lowered, nor can they be raised synchronously with the intelligent construction platform. If installation to a higher floor is required, they often need to be disassembled, transported to the higher floor by tower crane, and then reinstalled. This type of hoisting platform brings many inconveniences to construction, as disassembly and reinstallation are very troublesome and delay the construction process. For example, a novel unloading platform disclosed in patent publication number CN220247657U is intelligently fixed at a certain height. If it needs to be raised, it needs to be disassembled, hoisted to a higher position, and then reinstalled, which is very inconvenient. Utility Model Content

[0004] The purpose of this utility model is to provide a hoisting platform for construction sites to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hoisting platform for construction sites, comprising a platform, wherein the platform is connected to a platform guide rail for lifting and adjusting its height, the platform guide rail being able to be lifted along a building wall, a plurality of diagonal braces are provided below the platform, the lower ends of the diagonal braces are connected to the platform guide rails, a pin sensor is provided at the connection between the diagonal braces and the platform, there are two platform guide rails, the two platform guide rails are correspondingly connected to the two sides of the platform, a lifting truss is connected above the two platform guide rails, a pulley is provided on the lifting truss, and a rope for lifting the platform is connected between the pulley and the platform.

[0006] Further preferably, each of the material platform guide rails has several wall-mounted guide seats connected to its side away from the material platform. The material platform guide rails are fixed to the building wall via the wall-mounted guide seats, and the material platform guide rails can be lifted upwards along the wall-mounted guide seats. The wall-mounted guide seats are used for connecting the material platform guide rails to the building wall.

[0007] Further preferably, the wall-mounted guide seat includes a wall-mounted fixing plate, on which two symmetrically arranged connecting plates are provided. Each of the two connecting plates, at its end furthest from the wall-mounted fixing plate, is a locking plate that engages with the material platform guide rail. A roller is connected between the two connecting plates and is rolledly connected to the side of the material platform guide rail furthest from the material platform. The wall-mounted fixing plate is used to connect to the building wall, the locking plate is used to engage with the material platform guide rail to limit its movement, and the roller is used to abut against the material platform guide rail, limiting its movement and facilitating the movement of the material platform guide rail relative to the wall-mounted guide seat.

[0008] Further preferably, a rotating shaft connects the two connecting plates, and a weighing block is connected to the rotating shaft. The weighing block is rotatably positioned above the roller and is restricted from rotating downwards by the roller. The end of the weighing block away from the rotating shaft has an upwardly curved hook that engages with the material platform guide rail. The weighing block is used to engage with the material platform guide rail; by hooking the guide rail at its end, it not only connects the wall-mounted guide seat to the material platform guide rail but also prevents the material platform guide rail from sliding down.

[0009] Further preferably, the wall-mounted fixing plate has several rectangular waist-shaped fixing holes, and several reinforcing ribs are provided between the wall-mounted fixing plate and the connecting plate. Both the upper and lower ends of the clamping plate are curved away from the wall-mounted fixing plate. The curved ends of the clamping plate facilitate the lifting of the material table guide rail and prevent interference.

[0010] Further preferably, the material platform guide rail includes two symmetrically arranged guide rail plates. Each guide rail plate has a rectangular groove on its opposite side for engaging with a locking plate. A plurality of connecting and limiting plates are connected between the two guide rail plates, allowing for engagement with hooks for weighing blocks. Each guide rail plate has a plurality of evenly arranged connecting holes for insertion and connection with the material platform. The guide rail plates serve for guiding and limiting movement, using the rectangular grooves to engage with the locking plates, thus achieving installation limiting and movement guidance for the material platform guide rail. The connecting holes are used for connecting and fixing the lifting truss, material platform, diagonal braces, and guardrails.

[0011] In a further preferred embodiment, a guardrail is provided above the material platform, with openings on the sides of the guardrail near the two material platform guide rails. Several hanging plates are provided on the guardrail, and both the material platform and the guardrail have insertion holes near the material platform guide rails that mate with the connecting holes. The guardrail provides safety protection, the hanging plates are used to connect ropes, and the insertion holes mate with the connecting holes on the material platform guide rails.

[0012] In a further preferred embodiment, the opening side of the material platform displacement guardrail is rotatably connected to a flap, which facilitates flipping and makes it convenient to load building materials or construction tools into the material platform and limit their movement after loading, thereby improving safety.

[0013] Further preferably, there are four diagonal braces, and a stable truss connects the four diagonal braces to ensure the support stability of the diagonal braces.

[0014] Beneficial effects: The construction site hoisting platform of this utility model, through the structural arrangement of platform guide rail, lifting truss, pulleys and wall-mounted guide seat, can achieve the overall lifting of the hoisting platform by lifting the platform guide rail relative to the wall-mounted guide seat, or by lifting the platform relative to the platform guide rail by the lifting truss, pulleys and ropes. Both lifting methods of the hoisting platform can meet the needs of construction operations. It can be used alone or in conjunction with an intelligent building platform to achieve lifting as the building floors are raised.

[0015] The pin sensor can measure the load inside the material platform and determine whether the weight of the building materials or construction tools inside the platform exceeds the bearing capacity, thus preventing the risk of structural deformation, breakage or collapse of the diagonal brace due to overloading, or even the collapse of the entire hoisting platform.

[0016] By using the wall-mounted guide seat structure, the guide rail of the material platform can only be lifted upwards and cannot be lowered, which can improve the safety of the hoisting material platform.

[0017] This hoisting platform meets the material carrying and transfer needs in construction. It is safe and reliable, and does not require disassembly and reassembly when lifting is needed. The lifting method is simple and fast, which has greater convenience and can improve the construction process. Attached Figure Description

Detailed Implementation

[0023] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0024] like Figure 1-3 As shown, this application provides a solution for a hoisting platform for construction sites, including a platform 2. The platform 2 is connected to a platform guide rail 1 for lifting and adjusting its height. The platform guide rail 1 can be lifted along the building wall. Several diagonal braces 3 are provided below the platform 2. The lower end of the diagonal braces 3 is connected to the platform guide rail 1. A pin sensor 9 is provided at the connection between the diagonal braces 3 and the platform 2. There are two platform guide rails 1, which are connected to the two sides of the platform 2 respectively. A lifting truss 4 is connected above the two platform guide rails 1. The lifting truss 4 is provided with pulleys 5. A rope for lifting the platform 2 is connected between the pulleys 5 and the platform 2.

[0025] The hoisting platform provided in this solution is installed on the building wall to enable the hoisting of platform 2. This hoisting platform can be used in an intelligent construction platform and can be raised along with the platform. Specific raising methods include:

[0026] 1. The material platform 2 is lifted by lifting truss 4 and pulley 5. One end of the rope is connected to the material platform 2, and the other end of the rope is pulled manually or by machine, such as by a rope winder to wind the rope, so as to lift the material platform 2 upward along the material platform guide rail 1. After lifting to a certain height, the material platform 2 is fixed to the material platform guide rail 1.

[0027] Second, the entire hoisting platform can be lifted by raising the platform guide rail 1. The platform can be lifted as a whole by raising the platform guide rail 1, which can be lifted along the building wall. For example, the platform guide rail 1 is connected to the lifting mechanism or can be pulled upwards.

[0028] In this design, material platform 2 is used for transferring building materials, such as formwork, reinforcing bars, and other building materials or construction tools. When this hoisting platform is used in the intelligent construction platform, platform 2 is positioned directly below the overhead crane of the intelligent construction platform, facilitating the hoisting of building materials or construction tools on platform 2 to the top Bailey bridge of the intelligent construction platform or to the required height. Pin-shaft sensor 9 is used to measure the load within platform 2, determining whether the weight of the building materials or construction tools exceeds the bearing capacity of the diagonal brace 3, preventing structural deformation, breakage, or collapse of the diagonal brace 3 due to overloading. The structure of the two platform guide rails 1 ensures stable installation of platform 2 and also ensures stable lifting of platform 2. Lifting truss 4 is used for installing pulleys 5, which support the ropes, facilitating the pulling of the ropes to lift platform 2 upwards.

[0029] Please continue to refer to Figure 1-3 As shown, each material platform guide rail 1 has several wall-mounted guide seats 6 connected to its side away from the material platform 2. The material platform guide rail 1 is fixed to the building wall through the wall-mounted guide seats 6 and the material platform guide rail 1 can be lifted upward along the wall-mounted guide seats 6.

[0030] In this scheme, the material platform guide rail 1 is fixedly connected to the building wall through the wall-mounted guide seat 6, and the material platform guide rail 1 can be lifted along the wall-mounted guide seat 6 to realize the overall lifting of the hoisting material platform.

[0031] Reference Figure 4 As shown, based on the above scheme, the wall-mounted guide seat 6 includes a wall-mounted fixing plate 61. The wall-mounted fixing plate 61 is provided with two symmetrically arranged connecting plates 62. Each of the two connecting plates 62 is provided with a clamping plate 63 that is engaged with the material table guide rail 1 at the end away from the wall-mounted fixing plate 61. A roller 64 is connected between the two connecting plates 62 and is rolledly connected to the side of the material table guide rail 1 away from the material table 2.

[0032] The wall-mounted fixing plate 61 is used to connect to the building wall, and the connecting plate 62 is used for the installation of the clamping plate 63 and the roller 64. The clamping plate 63 is used to engage with the material platform guide rail 1 to ensure the stable installation of the material platform guide rail 1. The roller 64 is used to support the rear side of the material platform guide rail 1. Through the cooperative design of the roller 64 and the clamping plate 63, the front and rear limits of the material platform guide rail 1 are ensured. Multiple wall-mounted guide seats 6 are set along the length of the material platform guide rail 1 to ensure the stable installation of the material platform guide rail 1. Moreover, the structural design of the roller 64 facilitates the upward movement of the material platform guide rail 1 along the wall-mounted guide seats 6, reduces frictional resistance, and reduces the difficulty of lifting the material platform guide rail 1. Only a relatively small pulling force is required to pull the material platform guide rail 1 upward.

[0033] Based on the above solution, in another solution of this application, a rotating shaft 65 is connected between the two connecting plates 62, and a weighing block 66 is connected to the rotating shaft 65. The weighing block 66 is rotatably positioned above the roller 64 and is restricted by the roller 64 from rotating downwards. The end of the weighing block 66 away from the rotating shaft 65 is provided with an upwardly curved hook that engages with the material table guide rail 1.

[0034] In this design, by setting a rotating shaft 65 between the two connecting plates 62, the connection strength between the two connecting plates 62 is improved, and it also serves as a rotational support for the weighing block 66, ensuring that the weighing block 66 can rotate with the rotating shaft 65 as support. The weighing block 66 can hook onto the platform guide rail 1 through its upwardly curved hook, strengthening the connection between the wall-mounted guide seat 6 and the platform guide rail 1. At the same time, the roller 64 can limit the rotation of the weighing block 66, so that the weighing block 66 can only rotate upward and not downward, thereby limiting the movement of the platform guide rail 1, ensuring that the platform guide rail 1 can only move upward and not downward, thus preventing the platform guide rail 1 from moving downward relative to the wall-mounted guide seat 6 and preventing the platform 2 from falling. Furthermore, when the platform guide rail 1 is pulled upward, the weighing block 66 can rotate upward and separate from the platform guide rail 1, without hindering the lifting of the platform guide rail 1.

[0035] Based on the above solution, in another solution of this application, the wall-mounted fixing plate 61 is provided with a number of rectangular waist hole structure fixing holes 67, and a number of reinforcing ribs 68 are provided between the wall-mounted fixing plate 61 and the connecting plate 62. The upper and lower ends of the clamping plate 63 are curved in an arc shape away from the wall-mounted fixing plate 61.

[0036] In this design, the rectangular waist-shaped fixing hole 67 facilitates the passage of bolts or fixing rods, and allows for fine-tuning of the left and right positions of the wall-mounted fixing plate 61, thus fixing the wall-mounted fixing plate 61 to the building wall and ensuring that the material platform guide rail 1 is installed vertically. The reinforcing rib plate 68 is used to improve the connection strength between the wall-mounted fixing plate 61 and the connecting plate 62, and to improve the overall structural strength of the wall-mounted guide seat 6. The upper and lower ends of the clamping plate 63 are curved, which facilitates the vertical movement of the material platform guide rail 1 relative to the wall-mounted guide seat 6, and prevents interference or jamming between the upper and lower ends of the clamping plate 63 and the material platform guide rail 1.

[0037] Reference Figure 4 As shown, based on the above scheme, in one aspect of this application, the material platform guide rail 1 includes two symmetrically arranged guide rail plates 11. The opposite sides of the two guide rail plates 11 are provided with rectangular grooves for engaging with the clamping plate 63. A plurality of connecting limiting plates 12 are connected between the two guide rail plates 11, which can be engaged with the hooks of the weighing clamping block 66. A plurality of connecting holes 13 are provided on each of the two guide rail plates 11, which are evenly arranged vertically. The connecting holes 13 are used for insertion and connection with the material platform 2.

[0038] In this design, guide rail plates 11 are used for the installation and lifting guidance of the material platform 2. Two guide rail plates 11 are engaged on both sides of the connection point of the material platform 2 to form a locking position, ensuring that the lifting of the guide rail plates 11 can move along the direction of the guide rail plates 11. Simultaneously, the material platform 2 is fixed relative to the guide rail plates 11 through connecting holes 13. Pins or bolts are inserted into the insertion holes at the connection point of the connecting holes 13 and the material platform 2 to fix the material platform 2 and the material platform guide rail 1. The rectangular groove on the guide rail plate 11 is used to engage the locking plate 63 of the wall-mounted guide seat 6, ensuring the position of the material platform guide rail 1 relative to the wall-mounted guide seat 6, thereby enabling the installation of the material platform guide rail 1 on the building wall; and the hook of the weighing locking block 66 forms a limit to prevent the material platform guide rail 1 from falling. The connecting limiting plate 12 cooperates with the weighing locking block 66 to limit the weighting locking block 66, preventing the material platform guide rail 1 from falling relative to the wall-mounted guide seat 6.

[0039] Reference Figure 1-3 As shown, based on the above scheme, in one scheme of this application, a guardrail 21 is provided above the material platform 2. The side opening of the guardrail 21 near the two material platform guide rails 1 is provided. Several hanging plates 22 are provided on the guardrail 21. The material platform 2 and the end of the guardrail 21 near the material platform guide rail 1 are provided with insertion holes that cooperate with the connection holes 13.

[0040] In this design, guardrail 21 is used for protection and obstruction to prevent building materials or construction tools placed on the material platform 2 from falling, thus eliminating safety hazards. The guardrail 21 has an opening near the end of the material platform guide rail 1, facilitating the transfer of building materials or construction tools from the scaffolding to the material platform 2. Hanging plate 22 is used to connect ropes, serving as a connection between the material platform guide rail 1 and the material platform 2, improving the installation stability of the material platform 2; it can also be used to connect ropes to the pulley 5, facilitating the lifting of the material platform 2. The insertion holes on the material platform 2 and guardrail 21 mate with the connection holes 13 on the material platform guide rail 1, allowing the material platform 2 to be fixed relative to the material platform guide rail 1 by inserting pins or bolts.

[0041] Reference Figure 1 As shown, preferably, a flap 7 is rotatably connected to the opening side of the displacement guardrail 21 of the material platform 2. By setting the flap 7 at the opening, when the flap 7 is flipped up, it can block the falling of building materials or construction tools placed on the material platform 2, thus preventing safety issues. When the flap 7 is turned down to a horizontal position, it is convenient to move building materials or construction tools onto the material platform 2.

[0042] Reference Figure 1-3 As shown, in one embodiment of this application, there are four diagonal braces 3, and a stabilizing truss 8 connects the four diagonal braces 3.

[0043] In this design, two of the four diagonal braces 3 are longer, while the other two are relatively shorter. The two shorter diagonal braces 3 are positioned on the inner sides of the two longer diagonal braces 3. One long and one short diagonal brace 3 are located on the left side of the platform 2, while the other long and short diagonal brace 3 are located on the right side of the platform 2, providing front and rear support to ensure its stability. The stabilizing truss 8 connects the four diagonal braces 3, ensuring their relative stability and providing mutual tension to further enhance the stability of the platform 2.
