[0028] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0029] Example 1

[0030] Reference Figure 1 and Figure 5 , is the first embodiment of the present invention, which provides an equipment maintenance device for a thermal power plant, including a maintenance unit 100, a working unit 200 and a redundant unit 300. The maintenance unit 100 is used to be placed on one side of the thermal power equipment to be repaired, and the working unit 200 is used to lower the ladder 201b and make the bonding plate 203d contact the placement surface. When the maintenance unit 100 is working, its redundant unit 300 can make the bonding plate 203d adsorbed on the placement surface according to the weight it bears, thereby preventing the maintenance unit 100 from tipping over. Most thermal power plants use solidified floors, which are sealed and water-repellent, hardened and wear-resistant, and durable. The soft pad 203e at the bottom of the bonding plate 203d is coated with sealing oil, which helps the soft pad 203e to fit tightly with the placement surface, thereby making the bonding plate 203d, the soft pad 203e and the placement surface sealed and fitted, and keeping the negative pressure adsorption of the bonding plate 203d stable.

[0031] Specifically, the maintenance unit 100 includes a maintenance platform 101, four groups of support legs 102 are installed at the bottom of the maintenance platform 101, a fence 103 is installed on the top side of the maintenance platform 101, the fence 103 improves the safety of its workers during maintenance, an auxiliary plate 104 is installed on the outer wall of the fence 103, a hoisting piece 105 is installed on one side of the auxiliary plate 104, the hoisting piece 105 is used to hoist the components required for maintenance, and can hoist some heavier components of thermal power equipment, a hydraulic rod 106a is installed inside the support leg 102, and a universal wheel 106b is installed at the bottom end of the hydraulic rod.

[0032] Operation process: When the thermoelectric equipment is being repaired, the hydraulic rod 106a drives the universal wheel 106b to extend and retract, so that the universal wheel 106b is retracted into the inside of the support leg 102, so that the support leg 102 is in contact with the placement surface. At this time, the maintenance platform is not easy to shift, and the thermoelectric equipment is disassembled and replaced. Most of the thermoelectric equipment is heavy, and the staff can lift the heavier parts through the lifting parts 105, so as to facilitate the maintenance work of the maintenance personnel.

[0033] Example 2

[0034] Reference Figure 1-Figure 3 , which is the second embodiment of the present invention, and this embodiment is different from the first embodiment in that: a working unit 200 includes an escalator assembly 201 arranged on a maintenance platform 101, an output assembly 202 is installed on one side outer wall of the support leg 102, and a bonding assembly 203 is installed at the bottom of the maintenance platform 101. When it is necessary to repair a certain thermoelectric device, the maintenance platform 101 can be moved to one side. At this time, the output assembly 202 can drive the escalator assembly 201 to rotate, so that the escalator assembly 201 rotates and contacts the ground, and when the escalator assembly 201 rotates, the escalator assembly 201 drives the bonding assembly 203 to move through the bending assembly 204 installed on one side, and the bonding assembly 203 contacts the placement surface.

[0035] Specifically, the escalator assembly 201 includes a support block 201a arranged on the maintenance platform 101, and a ladder 201b is installed on the outer wall of the support block 201a. The ladder 201b is used for workers to climb up to the maintenance platform 101. The outer wall of the ladder 201b is installed with a rotating shaft 201c, and the rotating shaft 201c is used to be connected to the output assembly 202 for transmission.

[0036] Furthermore, the output component 202 includes a bracket 202a arranged on the support leg 102, and an output motor 202b is installed on the outer wall of the bracket 202a. The output shaft 202c of the output motor 202b rotates to drive the belt 202d to move, and the belt 202d drives the rotating shaft 201c to rotate, thereby controlling the state of the ladder 201b.

[0037] Furthermore, the bonding component 203 includes a containing frame 203a arranged on the maintenance platform 101, the inner wall of the containing frame 203a is installed with a sliding plate 203b, the outer wall of the sliding plate 203b is matched with the inner wall of the containing frame 203a, the bottom of the sliding plate 203b is installed with an extension column 203c, the bottom of the extension column 203c is installed with a bonding plate 203d, and the bottom of the bonding plate 203d is installed with a soft pad 203e. When the bonding plate 203d moves down and contacts the placement surface, the soft pad 203e makes the bonding plate 203d and the placement surface be tightly fitted, so that the piston block 206f moves to negatively adsorb the bonding plate 203d on the placement surface.

[0038] Furthermore, the bending assembly 204 includes a first support plate 204a arranged on the ladder 201b, the first support plate 204a is connected to the first bending rod 204b through a pin, and the first bending rod 204b, the second bending rod 204c and the third bending rod 204d are all connected through a pin, and one end of the third bending rod 204d is connected to the second support plate 204e through a pin. When the output motor 202b reverses to retract the ladder 201b, its bending rod also pulls the bonding plate 203d at the same time as the ladder 201b moves, so that the bonding plate 203d is no longer in contact with the placement surface.

[0039] The rest of the structure is the same as that of Example 1.

[0040] Operation process: When performing maintenance, the maintenance unit 100 moves to one side of the thermoelectric device. At this time, the output motor 202b rotates to drive the output shaft 202c to rotate. The output shaft 202c rotates through the belt 202d to drive the ladder 201b to rotate, so that the retracted ladder 201b is rotated and falls to contact the placement surface. When the ladder 201b rotates, its first bending rod 204b, second bending rod 204c and third bending rod 204d are bent. At this time, the bonding plate 203d is no longer contracted by the tension of the first bending rod 204b, the second bending rod 204c and the third bending rod 204d. At this time, the bonding plate 203d contacts the placement surface through its own gravity.

[0041] Example 3

[0042] Reference Figure 1-Figure 6 , which is the third embodiment of the present invention. This embodiment is different from the above embodiments in that: when a worker stands on the maintenance platform 101 and the hoisting member 105 is hoisted, all of its weight is borne by the redundant unit 300 installed on the maintenance platform 101. The redundant unit 300 includes a lifting component 301 installed on the maintenance platform 101. At this time, the lifting component 301 moves with the change of weight, thereby driving the rotating component 302 on the bottom side of the lifting component 301 to rotate. The rotating component 302 causes the bonding component 203 to be gradually negatively adsorbed on the placement surface. The greater the pressure on the lifting component 301, the greater the negative pressure adsorption force of the bonding component 203, so that the maintenance platform 101 is not easy to tilt. A support component 303 is installed inside the bonding component 203. The support component 303 is used to limit the rotating component 302. A flow component 304 is installed inside the bonding component 203. The flow component 304 is used to connect the rotating component 302, the adsorption component and the placement surface.

[0043] Furthermore, the lifting assembly 301 includes a support spring 301a arranged on the maintenance platform 101, and a cross plate 301b is installed on the top of the support spring 301a. At this time, there is a certain gap between the cross plate 301b and the maintenance platform 101, which is the movement redundancy of the cross plate 301b after the pressure is applied. A support rod 301c is installed at the bottom of the cross plate 301b, and a contact pressure convex ball 301d is installed on the outer wall of the support rod 301c. The support rod 301c moves downward to drive the contact pressure convex ball 301d to contact the arc groove 302b of the rotating circle 302a. Four groups of limit blocks 301e are installed on the top of the maintenance platform 101. The limit blocks 301e are evenly distributed on the top side of the maintenance platform 101 to prevent the support spring 301a from being damaged by excessive pressure.

[0044] Furthermore, the rotating assembly 302 includes a rotating ring 302a installed on the inner top wall of the accommodating frame 203a through a bearing, the inner wall of the rotating ring 302a is provided with an arc groove 302b, its support rod 301c extends into the interior of the rotating ring 302a, and the contact pressure convex ball 301d is embedded in the interior of the arc groove 302b, the bottom of the rotating ring 302a is installed with a bottom plate 302c, the bottom of the bottom plate 302c is installed with a screw 302d, the outer wall of the screw 302d is meshed with an internal thread block 302e, and the bottom of the internal thread block 302e is installed with a piston block 302f, the rotation of the rotating ring 302a drives the screw 302d to rotate, the rotation of the screw 302d drives the internal thread block 302e to move upward, and the movement of the internal thread block 302e causes the metal bellows 304b to gradually have a negative pressure.

[0045] Furthermore, the support assembly 303 includes a fixed block 303a disposed in the accommodating frame 203a, and a telescopic rod 303b connected to the piston block 302f is installed at the bottom of the fixed block 303a. The telescopic rod 303b is used to limit the axial rotation of the piston block 302f to ensure that the piston block 302f can move up and down.

[0046] Furthermore, the circulation component 304 includes a partition 304a arranged in the containing frame 203a, and a metal bellows 304b is installed at the bottom of the partition 304a. The bottom end of the metal bellows 304b is connected to the top of the extension column 203c. When the piston block 302f moves upward, the metal bellows 304b is connected to the adsorption hole 304c on the bonding plate 203d, so that the soft pad 203e and the bonding plate 203d can be adsorbed on the placement surface.

[0047] The rest of the structure is the same as that of Example 2.

[0048] Operation process: When the maintenance personnel climb up the maintenance platform 101 and the hoisting member 105 for hoisting, their weight is all borne by the horizontal plate 301b. The greater the weight, the more the horizontal plate 301b sinks. As the horizontal plate 301b sinks on the support spring 301a, the support rod 301c moves downward, and the contact and pressure convex ball 301d on the support rod 301c contacts the arc groove 302b of the rotating circle 302a, so that the contact and pressure of the support rod 301c drives The rotating ring 302a rotates, the rotating ring 302a rotates, the screw 302d rotates, the screw 302d rotates, the internal thread block 302e moves, the internal thread block 302e moves and the piston block 302f moves upward, so that the air pressure in the bottom area of ​​the piston block 302f becomes low, so that the bonding plate 203d and the soft cushion 203e are adsorbed on the placement surface, and as the pressure-bearing weight of the horizontal plate 301b increases, its adsorption becomes more reliable, and the accommodating The frame 203a and the bonding plate 203d are located in the bottom center area of ​​the maintenance platform 101. If the weight at a certain point on the top of the maintenance platform 101 is too heavy and has a tendency to tilt, the sliding plate 203b will fit with the inner wall of the containing block, so that the containing frame 203a, the sliding plate 203b and the bonding plate 203d will not tilt, thereby avoiding the maintenance platform 101 from tipping over and improving the safety of maintenance. When not under maintenance, the lifting parts 105 will share the weight on the fence 103 through the auxiliary plate 104. During maintenance, the weight of the lifting parts 105 and the staff can just press the bonding plate 203d and the air pressure of the placement surface to a slightly adsorbed state. At this time, the maintenance platform 101 does not need to perform anti-tilting operations when bearing the weight, and there is no requirement for its adsorption force. As the weight of the lifting and the weight above the cross plate 301b increases, the adsorption force gradually increases, thereby effectively preventing the maintenance platform 101 from tipping over.

[0049] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention can be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should be included in the scope of the claims of the present invention.
