Description

Technical Field

[0001] This utility model relates to the field of installation technology for irregular roofs, and in particular to an adjustable movable upper and lower passage suitable for installation on irregular roofs. Background Technology

[0002] In the construction industry, access channels are key facilities for ensuring worker safety and construction efficiency. For buildings with irregular roofs, traditional access channels are usually fixed to the side of the building. Their main function is to allow workers to move vertically between work surfaces at different heights to carry out various types of construction work such as insulation and structural maintenance. These channels usually use metal frame ladders, which are connected to the main building structure by welding or bolting to form a relatively stable and reliable channel structure, ensuring the safety of workers during the climbing process.

[0003] However, existing access channels have many drawbacks in practical applications. Due to the special characteristics of irregular roofs, the installation points are numerous and complexly distributed. The channels often cannot accurately adapt to the location requirements of each work area, causing workers to frequently detour or find suitable channels to move up and down, which seriously wastes construction time and labor costs. In addition, the height of irregular roofs is inconsistent, and the access channels cannot be flexibly adjusted according to the actual height changes. This results in some channels being either too long, causing wasted space and inconvenience for climbing, or too short, failing to meet the needs of workers to reach the designated work surface. This greatly limits the flexibility and convenience of construction and affects the progress and quality of the entire building construction project. Utility Model Content

[0004] In view of this, embodiments of the present invention provide an adjustable movable upper and lower channel suitable for installation on irregular roofs, to solve the technical problem that existing upper and lower channels are fixed on the detection side and are inconvenient to move and use.

[0012] Furthermore, the bottom surface of the support platform is provided with a guide rail structure, which includes two guide rail frames, two connecting plates, multiple locking pins, and multiple return springs. The two guide rail frames are horizontally slidably connected to the lifting platform. The multiple locking pins and multiple return springs are equally distributed on the two connecting plates. One connecting plate is vertically slidably connected below the guide rail frame. The return spring is connected between the connecting plate and the guide rail frame, and the locking pin can extend into the guide rail frame.

[0013] Furthermore, each of the connecting plates is provided with a telescopic rod at both ends, and the movable end of the telescopic rod is connected to the lower surface of the guide rail frame, so that the connecting plate can move up and down relative to the guide rail frame.

[0014] Furthermore, the locking pin is provided with an arc-shaped surface facing one end of the guide rail frame, and the multiple arc-shaped surfaces are all oriented in the same direction, all facing the opposite direction of the horizontal sliding of the lifting platform.

[0015] Furthermore, the lifting platform has through holes at both ends corresponding to each of the locking pins, which allow the locking pins to be inserted so that the lifting platform is unidirectionally restricted relative to the guide rail frame.

[0016] Furthermore, each of the guide rail frames is provided with multiple extension holes, and each of the locking pins is slidably connected to one of the extension holes.

[0017] Furthermore, a baffle is connected to one end of both guide rail frames, and an open track is connected to the end of each guide rail frame away from the baffle. Both open tracks extend outward from the two guide rail frames.

[0018] Furthermore, both the upper and lower ends of the reset spring are connected to spring seats, and the two spring seats are respectively inserted into the connecting plate and the guide rail frame.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be further described below with reference to the accompanying drawings. The following description presents a preferred embodiment of several possible embodiments of this utility model, intended to provide a basic understanding of the utility model, but not intended to identify the key or decisive elements of the utility model or to limit the scope of protection sought.

[0026] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0027] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0028] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures. Also, it should be understood that, for ease of description, the dimensions of the various parts shown in the figures are not drawn to actual scale.

[0029] It should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] Please refer to Figures 1 to 2 The present invention provides an adjustable mobile access channel suitable for installation on irregular roofs, comprising a support platform 1, a connecting platform 3, a hydraulic lifting platform 2, and an electric tractor 6.

[0031] Please refer to Figures 2 to 3 Example 1: The support platform 1 serves as the basic load-bearing structure of the entire device, possessing sufficient strength and stability to withstand the weight of workers and related equipment. Its bottom surface is equipped with a guide rail structure 5, which consists of two guide rail frames 51, two connecting plates 52, multiple locking pins 55, multiple return springs 53, telescopic rods 54, and other components.

[0032] The electric tractor 6 is equipped with a lifting platform 7 on its upper end. The electric tractor 6 is specifically an electric construction site small tractor, whose built-in power structure can drive to move up and down the passage.

[0033] It should be noted that the two guide rail frames 51 are arranged in parallel and can be horizontally slidably connected with the lifting platform 7. Multiple locking pins 55 and multiple return springs 53 are evenly distributed on the two connecting plates 52.

[0034] Each connecting plate 52 is vertically slidably connected to the bottom of the guide rail frame 51. Both ends of the connecting plate 52 are provided with telescopic rods 54. The movable end of the telescopic rod 54 is connected to the lower surface of the guide rail frame 51. In this way, when the guide rail frame 51 moves or is subjected to force, the telescopic rod 54 can extend and retract accordingly, causing the connecting plate 52 to move up and down relative to the guide rail frame 51, thereby ensuring the flexibility and stability of the entire guide rail structure 5. The return spring 53 is connected between the connecting plate 52 and the guide rail frame 51, and the locking pin 55 can extend into the guide rail frame 51.

[0035] Furthermore, the locking pin 55 is designed with an arc-shaped surface 551 at one end facing the guide rail frame 51. The multiple arc-shaped surfaces 551 are oriented in the same direction, all facing the opposite direction of the horizontal sliding of the lifting platform 7.

[0036] During implementation, when the lifting platform 7 slides horizontally into the guide rail frame 51, the arc-shaped surface 551 can smoothly contact and be squeezed with the edge of the lifting platform 7, causing the locking pin 55 to squeeze the connecting plate 52 and move away from the guide rail frame 51 through the connecting plate 52. At this time, the return spring 53 is pushed and stretched. After the lifting platform 7 continues to slide to the appropriate position, the locking pin 55 automatically pops out under the restoring force of the return spring 53 and inserts into the insertion holes 71 at both ends of the lifting platform 7, thereby realizing the one-way locking of the lifting platform 7 and preventing it from sliding in the opposite direction without authorization.

[0037] Please refer to Figure 2 Each guide rail frame 51 has multiple extension holes 512 through it, and each locking pin 55 is slidably connected to an extension hole 512, which ensures the stability and accuracy of the locking pin 55 during the movement.

[0038] One end of each of the two guide rail frames 51 is connected to a baffle 513, which serves as a limit to prevent the lifting platform 7 from slipping off the rear end of the guide rail frame 51. Both guide rail frames 51 are connected to an open track 511 at the end away from the baffle 513. Both open tracks 511 extend outward from the guide rail frame 51, providing a convenient guide channel for the installation and removal of the lifting platform 7.

[0039] Please see Figure 4 In an optional embodiment, the upper and lower ends of the reset spring 53 are connected to spring seats 531, and the two spring seats 531 are respectively inserted into the connecting plate 52 and the guide rail frame 51. This connection method not only facilitates the installation and replacement of the reset spring 53, but also ensures that it can stably play the reset role during operation, thereby improving the reliability and service life of the entire guide rail structure 5.

[0040] In this embodiment, the connecting platform 3 is installed above the hydraulic lifting platform 2 and connected to the support platform 1 through the hydraulic lifting platform 2. The front of the connecting platform 3 is provided with a telescopic channel 4. The telescopic channel 4 can be adjusted in length according to actual needs so that it can extend above the support platform 1, making it convenient for workers to climb up and down. The telescopic channel 4 is made of high-strength material and has good stability and safety. Its surface is provided with anti-slip texture, which increases the safety of workers climbing.

[0041] Example 2: In this example, the telescopic channel 4 is a telescopic ladder. Its outer support end is hinged to one side of the connecting platform 3, and its movable end is hinged to the surface of the supporting platform 1 through a hinge seat to form an inclined up and down channel. At this time, when the connecting platform 3 is lifted by the hydraulic lifting platform 2, the telescopic channel 4 can naturally extend and retract to adapt to the change in distance between the supporting platform 1 and the connecting platform 1.

[0042] More specifically, the telescopic channel 4 is composed of multiple U-shaped structures that slide together, and each module is provided with a limiting end to prevent the modules from coming off each other. In addition, the telescopic channel 4 is made of high-strength alloy material to improve the load-bearing capacity of the connection between the modules when used at an angle.

[0043] The rear side of the connecting platform 3 is provided with a fixing structure, which consists of a fixing plate 33 and multiple bolt buckles 34. The fixing plate 33 is firmly connected to the connecting platform 3, and at least one bolt buckle 34 is provided on one side. By adding bolts to the bolt buckles 34, the fixing plate 33 can be firmly connected to the side of the building, ensuring the stability of the entire connecting platform 3 during operation.

[0044] In order to reduce the rigid contact between the fixed plate 33 and the connecting platform 3 and reduce the damage to the connecting platform 3 caused by vibration and impact, a number of buffer pads 32 are provided between the fixed plate 33 and the connecting platform 3.

[0045] The buffer pad 32 is made of elastic material, which can effectively absorb the vibration and impact energy generated during construction, extend the service life of the connection platform 3, and also help improve the stability of the connection.

[0046] In an optional embodiment, guardrails 31 are fixed on both sides of the upper surface of the connecting platform 3 to provide support positions and block protection.

[0047] It should be noted that the surface of the support platform 1 is also provided with an installation frame 8. The installation frame 8 is a rectangular frame, and its size corresponds to the base size of the hydraulic lifting platform 2, so that the base part of the hydraulic lifting platform 2 can be placed and restricted within the installation frame 8, and can be assembled and set up on-site for the entire upper and lower passage.

[0048] To facilitate the placement of the base of the hydraulic lifting platform 2 into the mounting frame 8, guide members 81 are provided on the outer edge of the upper surface of the mounting frame 8. The guide members 81 are inclined towards the inner side of the mounting frame 8 to facilitate good guidance of the hydraulic lifting platform 2.

[0049] The lifting platform 7 can support the support platform 1, allowing the support platform 1 to move under the drive of the electric tractor 6. The electric tractor 6 itself has good maneuverability and flexibility, and can be easily moved between different locations on the construction site, thereby meeting the dynamic needs of the upper and lower passage positions during the construction process.

[0050] In the actual construction process, firstly, according to the shape of the building roof and construction requirements, the electric tractor 6 is driven to the bottom position of the support platform 1, so that the guide rail structure 5 and the lifting platform 7 are guided, and the locking pin 55 is used to firmly insert with the lifting platform 7 to form a locking engagement. At this time, the lifting platform 7 is in the middle position of the support platform 1. Then, the lifting platform 7 lifts the support platform 1, so that the support platform 1 can move and change position with the electric tractor 6. After moving to the side position of the building, the support platform 1 is lowered, so that the support platform 1 is stably placed on the side position of the inspection. The height position of the connecting platform 3 is adjusted by the hydraulic lifting platform 2, so that the telescopic channel 4 can accurately extend above the support platform 1, and make the connecting platform 3 flush with the building surface. At the same time, the connecting platform 3 is firmly connected to the side of the building through the fixing structure to ensure the stability and safety of the entire upper and lower channel. If necessary, a ramp can also be laid between the connecting platform 3 and the building surface to complete the setting of the upper and lower channel.

[0051] When it is necessary to move the position of the access road, first disconnect the connection between the fixed structure and the side of the building, and then repeat the above-mentioned moving and adjusting process to move the access road to the new construction position. Then fix and adjust it again to continue to provide workers with a safe and convenient access road.

[0052] In this document, the directional terms such as front, back, top, and bottom are defined based on the position of the components in the accompanying drawings and their relative positions to each other, solely for the purpose of clarity and convenience in expressing the technical solution. It should be understood that these are relative concepts and can vary depending on different methods of use and placement; the use of these directional terms should not limit the scope of protection claimed in this application.

[0053] Where there is no conflict, the above embodiments and features described herein can be combined with each other.

[0054] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
