Description

Technical Field

[0001] This invention relates to a maintenance device, and more particularly to a maintenance device based on zero-carbon buildings. Background Technology

[0002] With the depletion of non-renewable energy sources and the environmental damage caused by their use, people are paying more and more attention to the development and utilization of renewable energy and zero-carbon buildings. Zero-carbon buildings refer to buildings with zero carbon emissions that can operate independently of the power grid and can rely on solar or wind power. People need to maintain zero-carbon buildings regularly.

[0003] Because zero-carbon buildings are quite tall, people need to use elevators to assist with maintenance work. However, traditional elevators have low safety measures, and accidents or even life-threatening situations can easily occur when people use them. Therefore, we are now developing a maintenance device based on zero-carbon buildings that can protect people. Summary of the Invention

[0004] In order to overcome the shortcomings of traditional elevators, such as low safety measures and the ease with which accidents can occur when people use them, the technical problem of this invention is to provide a maintenance device based on zero-carbon buildings that can protect people.

A first return spring for reset is connected between the front side of the leftmost sliding sleeve and the leftmost first guide bracket. A first return spring is also connected between the front side of the rightmost sliding sleeve and the rightmost first guide bracket. A first return spring for reset is also connected between the rear side of the two middle sliding sleeves and the two middle first guide brackets.

[0008] Furthermore, it also includes a lifting support mechanism, which comprises a first bearing seat, a second bearing seat, a spiral groove shaft, a rod-driven moving plate, a cylindrical cam, a first contact post, a fourth return spring, and a lifting seat. The four corners of the base top are each connected to a first bearing seat, and each corner is slidably connected to a movable first contact post. The first contact post is located below an adjacent first bearing seat, and the bottom of each first contact post is connected to a supporting lifting seat. A fourth return spring with a reset function is connected between the top of the lifting seat and the base. The guide groove plate has second bearing seats connected to its front and rear sides. The left side of the second bearing seat, away from each other, is rotatably connected to a spiral groove shaft, as is the right side of the second bearing seat, away from each other. The lower part of each spiral groove shaft passes through an adjacent first bearing seat. The hydraulic rod has rod-driven moving plates connected to its front and rear sides, with the lower part of the moving plates fitted onto adjacent spiral groove shafts. The bottom of each spiral groove shaft is connected to a rotatable cylindrical cam.

[0009] Furthermore, it also includes an auxiliary entry mechanism, which includes a second guide bracket, a foot pedal, a second contact rod, a second return spring, a wedge plate, and a third contact rod. The second guide bracket, which can provide guidance, is connected to the middle of the front side of the top of the base. The foot pedal is rotatably connected to the front side of the second guide bracket. The second contact rod is slidably connected to the left and right sides of the lower part of the second guide bracket. The second contact rod is connected to the rear side of the second contact rod and can move. The second return spring, which has a reset function, is connected between the front side of the wedge plate and the second guide bracket. The second return spring is sleeved on the adjacent second contact rod. Two third contact rods are connected to the lower front side of the base plate and are distributed on the left and right sides.

[0010] Furthermore, it also includes a tool placement mechanism, which includes a fixed slot plate, a limiting frame, and a third return spring.

Detailed Implementation

[0034] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0035] A maintenance device based on zero-carbon buildings, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the device includes casters 1, a base 2, a support platform 3, a hydraulic cylinder 4, a hydraulic rod 41, a guide groove plate 5, a linear guide rail 51, a connecting frame 6, a base plate 7, a push frame 8, a protective mechanism 9, and a buffer mechanism 10. Casters 1 are rotatably connected to all four corners of the base 2, facilitating movement of the device. Support platforms 3 are welded to the top left and right sides of the base 2. Hydraulic cylinders 4 are bolted to the center of the top of each support platform 3. Hydraulic rods 41 are connected to the upper side of the telescopic rods of the hydraulic cylinders 4, enabling the hydraulic cylinders 4 to... The pressure rod 41 moves up and down. The upper side of the support platform 3 is fixedly connected to the guide groove plate 5. The guide groove plate 5 is connected to the linear guide rail 51. The linear guide rail 51 is slidably connected to the connecting frame 6. The linear guide rail 51 can guide the connecting frame 6. The bottom of the two connecting frames 6 is connected to the base plate 7. The connecting frame 6 can make the base plate 7 move up and down. The middle of the rear side of the top of the base 2 is connected to the push frame 8. The base plate 7 is equipped with a protective mechanism 9. The protective mechanism 9 can protect people. The base 2 is equipped with a buffer mechanism 10.

[0036] like Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, the protective mechanism 9 includes a protective plate 91, a hinge block 92, a protective door panel 93, a rotating rod 95, and a fixing block 96. The protective plate 91 is fixedly connected to the top of the base plate 7. The left and right sides of the front of the protective plate 91 are rotatably connected to the hinge block 92. The protective door panel 93 is bolted to the hinge block 92. The protective door panel 93 can close the front of the protective plate 91. The lower rear side of the protective door panel 93 is rotatably connected to the rotating rod 95. Two fixing blocks 96 are connected to the upper front of the base plate 7. The fixing blocks 96 are distributed on the left and right sides and are located below the adjacent rotating rod 95. With the cooperation of the rotating rod 95 and the fixing block 96, the protective door panel 93 can be prevented from being opened.

[0037] like Figure 5 As shown, it also includes a handle 94. The front side of the protective door panel 93 is connected to a handle 94, which makes it easy for people to open the protective door panel 93.

[0038] like Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, the buffer mechanism 10 includes a first guide bracket 101, a sliding sleeve 102, a connecting rod 103, a fixing frame 104, a buffer plate 105, and a first return spring 106. Two first guide brackets 101 are bolted to the top left side of the base 2, distributed on both sides, and located at the lower left of the base plate 7. Two first guide brackets 101 are also bolted to the top right side of the base 2, also distributed on both sides, with the two first guide brackets 101 on the right side located at the lower right of the base plate 7. Sliding sleeves 102 are slidably connected to each first guide bracket 101, guiding the sliding sleeves 102. Connecting rods 103 are rotatably connected to each sliding sleeve 102, allowing the connecting rods 103 to rotate. For movement, buffer plates 105 are connected to both the left and right sides of the bottom of the base plate 7. The buffer plates 105 have a buffering function. A fixed frame 104 is connected to the middle of the bottom of each buffer plate 105. The fixed frame 104 on the left side is rotatably connected to the connecting rod 103 on the left side, and the fixed frame 104 on the right side is rotatably connected to the connecting rod 103 on the right side. The fixed frame 104 allows the connecting rod 103 to rotate. A first return spring 106 is connected between the front side of the leftmost sliding sleeve 102 and the leftmost first guide bracket 101. A first return spring 106 is also connected between the front side of the rightmost sliding sleeve 102 and the rightmost first guide bracket 101. A first return spring 106 is also connected between the rear side of the two middle sliding sleeves 102 and the two middle first guide brackets 101. The first return spring 106 allows the sliding sleeves 102 to return to their original position.

[0039] This equipment can be used when people need to maintain zero-carbon buildings. First, the equipment is moved to the destination using the pusher 8. At this time, the casters 1 will roll on the ground. When the destination is reached, the handle 94 rotates the protective door panel 93 to the side away from each other to open it. Then, the hinge block 92 rotates to the side away from each other. Then, tools are used to help people walk onto the base plate 7. After people walk onto the base plate 7, the hinge block 92 and the protective door panel 93 are manually rotated back to the side closer to each other, which in turn rotates the handle 94 back to its original position. Then, the rotating rod 95 is rotated so that the rotating rod 95 moves to the rear of the fixed block 96. In this way, when people are working at height, the protective door panel 93 will not... The system is opened to prevent accidental falls and protect people. Then, hydraulic cylinder 4 is activated, causing its telescopic rod to extend. This moves hydraulic rod 41 upwards. When hydraulic rod 41 contacts connecting frame 6, it also moves connecting frame 6 upwards, causing base plate 7 and its components to move upwards. This allows maintenance workers to be transported to the zero-carbon building requiring maintenance. Workers can then use tools to maintain the building, facilitating repairs. When base plate 7 moves upwards, it also moves buffer plate 105 and fixing frame 104 upwards, causing connecting rod 103 to rotate, thus moving the leftmost sliding sleeve 102 and the rightmost sliding sleeve 104 upwards. Sleeve 102 moves forward, and the two middle sleeves 102 move backward. The first return spring 106 is then compressed. After the worker finishes maintaining the zero-carbon building, the hydraulic cylinder 4's telescopic rod retracts, causing the hydraulic rod 41 to move downward and reset. Under the weight of the worker and the components on the base plate 7, the base plate 7 and its components also move downward and reset, causing the connecting frame 6 to move downward and reset. When the base plate 7 moves downward, it also drives the buffer plate 105 and the fixing frame 104 to move downward and reset. At this time, under the action of the first return spring 106, the leftmost and rightmost sleeves 102 move backward and reset, while the two middle sleeves 102 move forward and reset. Then, the connecting rod 103 is rotated to reset. In this way, the buffer plate 105 can buffer the base plate 7, preventing the base plate 7 from sliding down too fast and causing vibration. People will not feel uncomfortable. Then, the rotating rod 95 is rotated to reset. Then, the protective door plate 93 and the hinge block 92 are rotated to open to the side away from each other. Finally, people walk down from the base plate 7. After the workers get off, they manually rotate the protective door plate 93 and the hinge block 92 to the side closer to each other to reset. Repeat the above operation. This equipment can be used to assist people in maintaining zero-carbon buildings. Moreover, the protective plate 91 can also protect people and prevent them from falling from the base plate 7, thereby improving people's safety and reducing the occurrence of accidents.

[0040] like Figure 1 , Figure 2 , Figure 9 , Figure 10 , Figure 11 and Figure 12 As shown, it also includes a lifting support mechanism 11, which includes a first bearing seat 111, a second bearing seat 114, a spiral groove shaft 113, a rod-driven moving plate 112, a cylindrical cam 115, a first contact post 116, a fourth return spring 118, and a lifting seat 117. The first bearing seat 111 is fixedly connected to each of the four corners of the top of the base 2. The first contact post 116 is slidably connected to each of the four corners of the base 2. The first contact post 116 is located below the adjacent first bearing seat 111. A lifting seat 117 is welded to the bottom of each first contact post 116. The lifting seat 117 supports the equipment. A fourth return spring 118 is connected between the top of the lifting seat 117 and the base 2. The fourth return spring 118 allows the lifting seat 117 to return to its original position. The guide groove plate 5 is connected to the front and rear sides of the second bearing seat 114. The left side of the second bearing seat 114 is rotatably connected to the opposite side of the spiral groove shaft 113. The right side of the second bearing seat 114 is also rotatably connected to the opposite side of the spiral groove shaft 113. The lower part of the spiral groove shaft 113 passes through the adjacent first bearing seat 111. The hydraulic rod 41 is connected to the front and rear sides of the rod moving plate 112. The hydraulic rod 41 can make the rod moving plate 112 move up and down. The lower part of the rod moving plate 112 is sleeved on the adjacent spiral groove shaft 113. The rod moving plate 112 can make the spiral groove shaft 113 rotate. The bottom of the spiral groove shaft 113 is connected to the cylindrical cam 115. The cylindrical cam 115 can make the first contact post 116 move.

[0041] Because the base 2 has casters 1, the equipment may shake when it is bumped, causing workers working at height to lose their balance and potentially leading to accidents. When the hydraulic rod 41 moves upward, it also drives the rod-mounted moving plate 112 to move upward. At this time, with the engagement between the rod on the rod-mounted moving plate 112 and the thread of the spiral groove shaft 113, the spiral groove shaft 113 will rotate 180 degrees, causing the cylindrical cam 115 to rotate 180 degrees. This, in turn, causes the first contact post 116 and the lifting seat 117 to move downward, thereby stretching the fourth return spring 118. As a result, the lifting seat 117 will contact the ground, enabling the equipment to... The hydraulic rod 41 moves upward, causing the rod-mounted moving plate 112 to move upward. Under the cooperation between the rod on the rod-mounted moving plate 112 and the thread of the spiral groove shaft 113, the spiral groove shaft 113 will rotate 180 degrees to reset. Then, the cylindrical cam 115 will rotate 180 degrees to reset. At this time, under the action of the fourth reset spring 118, the first contact post 116 and the lifting seat 117 will move upward to reset. The above operation is repeated. When people use this equipment for maintenance, the lifting seat 117 can support the equipment and prevent it from shaking, thereby improving the stability of the equipment.

[0042] like Figure 1 , Figure 2 , Figure 13 and Figure 14 As shown, it also includes an auxiliary entry mechanism 12, which includes a second guide bracket 121, a foot pedal 122, a second contact rod 123, a second return spring 124, a wedge plate 125, and a third contact rod 126. The second guide bracket 121 is bolted to the middle of the front side of the top of the base 2. The foot pedal 122 is rotatably connected to the front side of the second guide bracket 121. The foot pedal 122 can assist people to walk onto the base plate 7. The second contact rod 123 is slidably connected to the left and right sides of the lower part of the second guide bracket 121. Wedge plates 125 are fixedly connected to the rear side of each rod 123. The wedge plates 125 can move the second contact rod 123. A second return spring 124 is connected between the front side of the wedge plate 125 and the second guide bracket 121. The second return spring 124 is sleeved on the adjacent second contact rod 123. The second return spring 124 can reset the wedge plate 125. Two third contact rods 126 are connected to the lower front side of the base plate 7. The two third contact rods 126 are distributed on the left and right sides. The third contact rods 126 can move the wedge plate 125.

[0043] Because the equipment is large and the base plate 7 is high, people need to use other tools to get onto the base plate 7, which wastes time. Initially, the second return spring 124 is in a compressed state. First, people walk onto the base plate 7 via the foot pedal 122. When the base plate 7 moves upward, it also drives the third contact rod 126 to move upward. At this time, the third contact rod 126 will not squeeze the wedge plate 125. Under the action of the second return spring 124, the wedge plate 125 and the second contact rod 123 will move backward, thereby causing the foot pedal 122 to rotate backward, so that the foot pedal 122... 22 is in a vertical state, thus saving space. When the base plate 7 moves downward, it drives the third contact rod 126 to move downward. At this time, the third contact rod 126 will squeeze the wedge plate 125, causing the wedge plate 125 and the second contact rod 123 to move forward and reset. The second contact rod 123 will push the foot pedal 122 forward, causing the foot pedal 122 to rotate and reset. Then, people can walk down through the foot pedal 122 and repeat the above operation. People do not need to use other tools to walk onto the base plate 7, thus saving manpower and time and improving people's work efficiency.

[0044] like Figure 1 , Figure 2 , Figure 15 and Figure 16 As shown, it also includes a tool placement mechanism 13, which includes a fixed slot plate 131, a limiting frame 132, and a third return spring 133. The fixed slot plate 131 is bolted to the rear side of the inner side of the protective plate 91. The limiting frame 132 is slidably connected to the middle of the front part of the fixed slot plate 131. The limiting frame 132 can limit the tool. Two third return springs 133 are connected between the limiting frame 132 and the fixed slot plate 131. The two third return springs 133 are arranged on the left and right sides. The third return springs 133 can reset the limiting frame 132.

[0045] When workers maintain zero-carbon buildings, they need to carry maintenance tools. However, the weight of these tools can hinder their movement. Placing the tools on the base plate 7 causes them to sway and potentially damage. To prevent this, the limiting frame 132 is moved forward, and the tools are placed between the limiting frame 132 and the protective plate 91, which compresses the third return spring 133. The limiting frame 132 is then released, and under the action of the third return spring 133, it moves backward. This limits the movement of the tools, eliminating the need to carry them and preventing damage to the tools.

[0046] like Figure 1 , Figure 2 and Figure 17As shown, it also includes an adjustment mechanism 14, which includes a connecting column 141, a push plate 142, and a torsion spring 143. The upper part of the push frame 8 is rotatably connected to the connecting column 141. The push plates 142 are welded to both the left and right sides of the connecting column 141. The push plates 142 can make the connecting column 141 rotate. The push plates 142 are connected to the push frame 8 on the side that is close to each other, and the torsion springs 143 can make the push plates 142 return to their original position.

[0047] When people move this device, they can move it using the push plate 142. The push plate 142 rotates with the person's hand, causing the connecting column 141 to rotate, which in turn causes the torsion spring 143 to twist. In this way, the person's hand does not need to remain in one position, thus saving manpower. When the device reaches its destination, the push plate 142 is released. At this time, under the action of the torsion spring 143, the push plate 142 and the connecting column 141 will rotate back to their original positions. The above operation is repeated. When people move this device, the push plate 142 can rotate according to the state of the person's hand, which is highly adaptable and saves manpower.

[0048] The embodiments described above are merely preferred embodiments of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications, improvements, and substitutions without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
