Abstract
Description
Technical Field
[0001] This application relates to the technical field of work platforms, and in particular to a movable aerial work platform for sloping roofs. Background Technology
[0002] During the construction of a sloping roof structure, two structural construction phases are typically performed. The first phase utilizes scaffolding with external safety protection to complete the fabrication of the ridge, sloping components, and other structural elements. During the second phase, because the external scaffolding needs to be dismantled promptly or the distance between the scaffolding and the main construction structure is too large, the general construction method involves using ladders leaning against the sloping roof. The bottom of the ladders is fixed to the roof using positioning structures. After workers are equipped with safety belts and safety ropes, the second phase of construction begins from the ladders.
[0003] Because of the long length of the sloping roof, the position of the ladder needs to be constantly changed during construction to complete the entire roof construction. This results in the need to constantly fix the ladder positioning structure for positioning, disassembling and moving, and repeatedly connecting the ladder to the positioning structure, making the construction process troublesome and inefficient. Summary of the Invention
[0004] To improve the construction efficiency of sloping roofs, this application provides a movable elevated work platform for sloping roofs.
[0005] The technical solution adopted in this application for a movable aerial work platform for sloping roofs is as follows: A movable elevated work platform for sloping roofs includes: A support frame, one end of which abuts against the roof ridge, and a pulley is provided at the end of the support frame connected to the roof ridge. The pulley is used to drive the support frame to move along the roof ridge. A positioning component is connected to the side of the support frame. The positioning component is used to reduce the probability of slippage between the support frame and the roof ridge when using the movable elevated work platform on the sloping roof. The footing is connected to one side of the support frame, and the footing is provided with crossbars for stepping on.
[0006] By adopting the above technical solution, during secondary construction of a sloping roof, the support frame is placed on the ridge and positioned there from the side using positioning devices. Workers can then proceed with construction by stepping on the horizontal bars of the support base. When working on different locations on the sloping roof, workers stand on the ridge, release the positioning devices, and use pulleys to move the support base and support frame together to the next construction position. The support frame is then repositioned using the positioning devices, reducing the need for repeated ladder positioning. The pulleys also facilitate the movement of the support frame and ladder, ultimately improving the construction efficiency of the sloping roof.
[0007] Optionally, the support frame includes a base frame, a first side frame, and a second side frame. One end of the base frame abuts against the ridge, and both sides of the base frame are located on the outer side of the ridge. The first side frame and the second side frame are both connected to the end of the base frame facing the ridge. The first side frame and the second side frame are located on both sides of the ridge and have a gap between them. The positioning element is installed on the first side frame.
[0008] By adopting the above technical solution, the base frame abuts against the ridge, facilitating the placement of the support frame. Gaps are left between the first and second side frames and the ridge, allowing the support frame to be installed on ridges of different sizes and enabling adjustment of its positioning. Simultaneously, the gaps also facilitate the sliding of the support frame on the ridge.
[0009] Optionally, the first side frame has a first through hole, and the positioning component includes a sliding rod. One end of the sliding rod passes through the first through hole and is positioned close to the ridge. The end of the sliding rod close to the ridge is connected to a first abutting block, which can rub against the ridge. The other end of the sliding rod is located on the side of the first side frame away from the ridge, and the footing abuts against the side of the sliding rod away from the ridge.
[0010] By adopting the above technical solution, when using the positioning component to position the support frame, the sliding rod can pass through the first through hole, allowing the abutment block to abut against the side wall of the ridge. This creates a situation where the abutment block and the second side frame clamp the ridge, ultimately positioning the support frame on the ridge. The foot abuts against the end of the sliding rod away from the ridge. When using the foot, the foot applies pressure towards the ridge, making the abutment block contact the ridge more tightly and reducing the probability of the support frame detaching from the ridge.
[0011] Optionally, the footing includes a working ladder and a clamping block. One end of the working ladder is hinged to one side of the base frame, and the clamping block is fixedly connected to the side of the working ladder facing the ridge. The side of the clamping block facing the ridge abuts against the end of the slide rod away from the ridge.
[0012] By adopting the above technical solution, the working ladder provides a standing platform for workers to carry out construction on the sloping roof. By hinged to the base frame, when the worker stands on the working ladder, the working ladder can convert part of the worker's weight into pressure towards the ridge through the clamping block, so that the abutment block is more tightly connected to the ridge and the probability of the support frame detaching from the ridge is reduced.
[0013] Optionally, an abutment cap is fixedly connected to the side of the sliding rod away from the roof ridge, and an elastic element is provided between the abutment cap and the side of the first side frame away from the roof ridge, and the elastic element is sleeved on the sliding rod.
[0014] By adopting the above technical solution, the abutment cap and the first side frame work together to limit the position of the elastic element. After the worker finishes construction, the elastic element can drive the slide rod to move away from the ridge, thereby separating the abutment block from the ridge. This makes it easier for the support frame to move on the ridge and facilitates construction at different locations on the sloping roof.
[0015] Optionally, the slide rod has a threaded peripheral wall, and a first limiting bolt is provided between the first abutting block and the first side frame, with the first limiting bolt threadedly connected to the slide rod.
[0016] By adopting the above technical solution, the first limiting bolt abuts against the side of the first side frame near the ridge, thereby controlling the maximum distance the slide rod can slide away from the ridge, thus reducing the probability that the sliding rod will slide and cause the abutment block to be too far from the ridge, resulting in the support frame detaching from the ridge.
[0017] Optionally, a second through hole is provided on the second side frame, and a thread is provided in the second through hole. An adjusting rod is connected to the second side frame, and the adjusting rod is threaded to the wall of the second through hole. A second abutting block is connected to the end of the adjusting rod facing the ridge, and a second limiting bolt is threaded between the second abutting block and the second side frame.
[0018] By adopting the above technical solution, a second through hole is opened on the second side and an adjustment rod is connected, thereby enabling the support frame to be applicable to a wider range of roof ridges and reducing the construction cost when constructing sloping roofs with different roof ridges.
[0019] Optionally, a safety buckle is fixedly connected to the side of the base frame away from the roof ridge, and the safety buckle has a connecting through hole.
[0020] By adopting the above technical solution, the safety buckle installed on the base frame can provide a fixed position for the safety belts and safety ropes suspended by workers, eliminating the need to set up a special structure for suspending safety ropes and safety belts on the ridge or other places, which facilitates the construction of sloping roofs and improves construction efficiency.
[0021] Optionally, the base frame is connected to a positioning plate arranged along the ridge direction, and the pulley is rotatably connected to the positioning plate.
[0022] By adopting the above technical solution, the pulleys are connected to the positioning plate on the base frame, which facilitates the installation and disassembly of the pulleys. At the same time, the positioning plate can also strengthen the connection strength of the base frame, thereby reducing the probability of the base frame being damaged.
[0023] Optionally, the abutment cap is arranged at an angle downwards toward the side of the working ladder away from the roof ridge.
[0024] By adopting the above technical solution, the inclined abutment cap can better abut against the working ladder, thereby reducing the probability that the abutment cap or the working ladder will be crushed when the working ladder presses against the slide rod.
[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. When constructing a sloping roof, a support frame is placed on the ridge and positioned there using positioning devices. The support frame's footing, connected to horizontal bars, provides a platform for workers to step on, thus creating a work platform on the roof. When a worker finishes work at one location and needs to move to the next, they return to the ridge from the footing and release the positioning devices. The support frame and footing are then propelled to the next work position by pulleys on the support frame. The support frame is then repositioned on the ridge using the positioning devices to allow for further work. This ultimately improves the efficiency of sloping roof construction. 2. Install the sliding rod on the first side frame and hinge the base to the support frame. When the worker stands on the crossbar of the support frame, the worker's weight can generate a force on the sliding rod in the direction of the ridge, so that the abutment block connecting the sliding rod is more tightly connected to the side of the ridge, thereby reducing the probability of the support frame detaching from the ridge. 3. The elastic element can move the sliding rod away from the ridge when the worker finishes construction and leaves the footing, thereby separating the abutment block from the ridge. This reduces the friction between the support frame and the ridge, making it easier for the worker to push the support frame and footing on the ridge, thus facilitating the construction of the sloping roof.

[0030] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0031] This application discloses a movable elevated work platform for sloping roofs. (Refer to...) Figure 1 The movable elevated work platform on the sloping roof includes a support frame 1 and a footing 5.
[0032] One end of the support frame 1 abuts against the ridge 2. A pulley 3 is provided at the end of the support frame 1 connected to the ridge 2, and the pulley 3 abuts against the top of the ridge 2. A positioning member 4 is connected to the side of the support frame 1, and the positioning member 4 can abut against the side of the ridge 2. One end of the footing 5 is hinged to one side of the support frame 1, and a crossbar 511 for stepping is provided inside the footing 5.
[0033] When constructing a sloping roof, the support frame 1 is first placed on the ridge 2, with one end of the support frame 1 connected to the pulley 3 abutting against the ridge 2. Then, the positioning piece 4 positions the support frame 1 on the ridge 2. Next, the footing 5 is connected to the support frame 1. Workers stand on the horizontal bar 511 on the footing 5 to carry out the sloping roof construction. After the workers have removed the sloping roof, they can move from the footing 5 to the ridge 2. Then, under the action of the pulley 3, the support frame 1 and the footing 5 can be pushed together to the next construction position. After the support frame 1 and the footing 5 reach the next construction position, the positioning piece 4 positions the support frame 1 on the ridge 2, thus allowing the next section of the sloping roof to be constructed.
[0034] The support frame 1 includes a base frame 11, a first side frame 12, and a second side frame 13. One end of the base frame 11 abuts against the ridge 2, and both sides of the base frame 11 are located on the outer side of the ridge 2. The base frame 11 is preferably composed of two transversely arranged connecting rods (not shown in the attached drawings) and two longitudinally connected reinforcing rods (not shown in the attached drawings), which reduces the overall weight of the base frame 11 and facilitates workers to move the base frame 11. The first side frame 12 and the second side frame 13 are both connected to the end of the base frame 11 facing the ridge 2. The first side frame 12 and the second side frame 13 are located on both sides of the ridge 2, and the distance between the supports of the first side frame 12 and the second side frame 13 is greater than the width of the ridge 2. The materials of the first side frame 12 and the second side frame 13 are preferably carbon steel, and the distance between the supports of the first side frame 12 and the second side frame 13 is preferably 600 mm to accommodate the extra-wide ridge 2. The positioning member 4 is installed on the first side frame 12 and can move towards the ridge 2 and rub against the side of the ridge 2.
[0035] When the positioning element 4 positions the support frame 1 on the ridge 2, the positioning element 4 moves towards the ridge 2, so that the side of the positioning element 4 facing the ridge 2 abuts against the side of the ridge 2. The positioning element 4 continues to move towards the ridge 2, so that the second side frame 13 abuts against the side of the ridge 2 away from the positioning element 4. Thus, the support frame 1 clamps the ridge 2 under the action of the positioning element 4 and the second side frame 13, thereby achieving the function of positioning the support frame 1 on the ridge 2.
[0036] The first side frame 12 has a first through hole 121. The positioning component 4 includes a slide rod 41, which is slidably connected to the wall of the first through hole 121. One end of the slide rod 41 passes through the first through hole 121 and is positioned towards the ridge 2. The end of the slide rod 41 near the ridge 2 is connected to a first abutment block 42. The area of the first abutment block 42 is larger than the area of the first through hole 121. Friction particles (not shown in the attached figure) are arranged on the side of the first abutment block 42 facing the ridge 2. The other end of the slide rod 41 is located on the side of the first side frame 12 away from the ridge 2. The footing 5 abuts against the side of the slide rod 41 away from the ridge 2.
[0037] After the support frame 1 is placed on the ridge 2, the footing 5 can be rotated towards the ridge 2, thereby moving the sliding rod 41 towards the ridge 2. After the sliding rod 41 moves towards the ridge 2, the abutment block abuts against the side wall of the ridge 2, thus completing the positioning of the support frame 1. The abutment block, by arranging friction particles, increases the friction between itself and the ridge 2, thereby reducing the probability of the support frame 1 detaching from the ridge 2.
[0038] A contact cap 43 is fixedly connected to the side of the slide rod 41 away from the ridge 2. The area of the contact cap 43 is larger than the cross-sectional area of the slide rod 41. The contact cap 43 is inclined downwards on the side facing the working ladder 51 away from the ridge 2. An elastic element 44 is sleeved on the slide rod 41. The elastic element 44 is located between the contact cap 43 and the first side frame 12. The elastic element 44 is in a compressed state. The elastic element 44 is preferably a spring and an elastic block.
[0039] When a worker leaves the footing 5 and stands on the ridge 2 after completing a section of construction on the sloping roof, the elastic element 44, which is in a compressed state, can exert a force on the abutment cap 43 away from the ridge 2, thereby causing the slide rod 41 to move away from the ridge 2. The footing 5 rotates away from the ridge 2, and the abutment block separates from the side wall of the ridge 2, reducing the friction between the support frame 1 and the ridge 2, making it easier for the worker to push the support frame 1 on the ridge 2 to move to the next construction position.
[0040] The sliding rod 41 has threads on its peripheral wall, and a first limiting bolt 45 is provided between the first abutment block 42 and the first side frame 12. The first limiting bolt 45 is threadedly connected to the sliding rod 41. The first limiting bolt 45 can control the maximum distance between the sliding rod 41 and the ridge 2, thereby controlling the maximum distance between the abutment block and the ridge 2, reducing the probability that the support frame 1 will detach from the ridge 2 due to excessive distance between the abutment block and the ridge 2.
[0041] The base frame 11 is connected to a positioning plate 7 that is arranged along the ridge 2. Connecting rods are fixedly connected to both ends of the positioning plate 7. The pulley 3 is rotatably connected to the positioning plate 7 along the arrangement direction of the positioning plate 7. A safety buckle 6 is fixedly connected to the side of the base frame 11 away from the ridge 2. The safety buckle 6 has a connecting through hole 61. The material of the safety buckle 6 is preferably 16# round steel.
[0042] When workers are constructing on a sloping roof, the safety belt and safety rope can be connected to the safety buckle 6 to achieve the connection between the safety rope and safety belt. There is no need to specially set up a structure for connecting the safety rope and safety belt in other places on the roof, which facilitates the construction of the sloping roof and improves the construction efficiency.
[0043] The second side frame 13 has a second through hole 131 with threads inside. The second side frame 13 is connected to an adjusting rod 132, which is threaded to the wall of the second through hole 131. The end of the adjusting rod 132 facing the ridge 2 is fixedly connected to a second abutment block 133. The side of the second abutment block 133 facing the ridge 2 is provided with friction particles. A second limiting bolt 134 is threaded between the second abutment block 133 and the second side frame 13.
[0044] By threading the adjusting rod 132 to the second through hole 131, the distance between the second abutting block 133 and the side wall of the ridge 2 can be adjusted by rotating the adjusting rod 132, thereby adjusting the distance between the first abutting block 42 and the second abutting block 133 to accommodate ridges 2 of different sizes.
[0045] The footing 5 includes a working ladder 51 and a clamping block 52. One end of the working ladder 51 is hinged to the base frame 11 near the first side frame 12. The clamping block 52 is fixedly connected to the side of the working ladder 51 facing the ridge 2. The side of the clamping block 52 near the ridge 2 is in contact with the abutment cap 43 away from the ridge 2. The side of the clamping block 52 facing the ridge 2 abuts against the abutment cap 43.
[0046] When workers are constructing the sloping roof, the working ladder 51 provides a standing position for the workers. By installing clamping blocks 52, direct contact between the working ladder 51 and the abutment cap 43 is avoided, thereby reducing the probability of the working ladder 51 being damaged. The clamping blocks 52 and the abutment cap 43 are installed close together, which reduces the probability of damage when the first abutment block 42 and the abutment cap 43 come into contact.
[0047] The implementation principle of the movable elevated work platform for sloping roofs in this embodiment is as follows: During the construction of a sloping roof, the support frame 1 is positioned on the ridge 2 using the positioning component 4. Workers can then step on the footing 5 connected to the support frame 1 to carry out the construction. After completing the construction of one section of the sloping roof, the worker can return to the ridge 2, then separate the positioning component 4 from the ridge 2. The pulley 3 then drives the support frame 1 and the footing 5 to slide on the ridge 2 to the next construction position. The positioning component 4 is then reconnected to the ridge 2 to begin construction on the next section of the sloping roof. This reduces the need for repeated positioning and ladder climbing steps in the original construction process. The pulley 3 facilitates the re-establishment of the work platform, ultimately improving the construction efficiency of sloping roofs.
[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
