Description

Technical Field

[0001] The utility model relates to the technical field of electric boilers, in particular to an electric boiler which is easy to maintain. Background Art

[0002] Electric boiler is also called electric heating boiler or electric heating boiler. As the name implies, it uses electricity as energy and converts it into thermal energy, which is then converted by the boiler to output steam, high-temperature water or organic heat carrier with a certain amount of thermal energy. The electric boiler body is mainly composed of an electric boiler steel shell, a computer control system, a low-voltage electrical system, an electric heating pipe, an inlet and outlet water pipe and a detection instrument. The heating methods of the electric boiler include electromagnetic induction heating and resistance PTC ceramic semiconductor heating. The electric boiler has the characteristics of no pollution, no noise, small footprint, easy installation and use, full automatic, safe and reliable, high thermal efficiency, etc. It is a green and environmentally friendly product.

[0003] After searching, it is found that in the patent publication number CN219934295U, a maintenance-friendly industrial electric boiler floor machine proposes that "by installing a bottom plate and universal wheels, the device can be moved, and by installing a lifting adjustment mechanism, the electric boiler can be raised and lowered. Furthermore, the electric boiler can be fixed to facilitate maintenance of the electric boiler; by installing a motor and a servo motor, power support can be provided for the device; by installing an adjustment mechanism, the device can be adjusted horizontally to facilitate maintenance of electric boilers of different sizes; by installing a second motor, power support can be provided for the device".

[0004] However, the above solution still has certain shortcomings in actual use. In this solution, a universal joint is used to displace the device, but there is no self-locking structure, which causes the device to slide spontaneously after being moved to the specified position, thereby greatly reducing the efficiency of daily maintenance of the device.

[0005] Furthermore, since the boiler cannot be rotated, the maintenance work on the surface of the boiler requires the boiler to be repeatedly disassembled and repositioned, which is inconvenient for the staff to maintain it. Utility Model Content

[0024] The rotating lifting structure 4 includes three support frames 401, a brake box 402 is fixedly installed on the top of the support frame 401 located in the center, and a transmission structure 403 is provided on the inner wall of the brake box 402. The output shaft of the transmission structure 403 is provided with two driving rollers 404, and the tops of the support frames 401 located on both sides are fixedly connected with resistance arc plates 405, and the tops of the resistance arc plates 405 are hinged with limit arc plates 406, and the inner walls of the support frames 401 located on both sides are rotatably connected with resistance rollers 407; by setting up the rotating lifting structure 4, the transmission chain structure can be used to prompt the driving roller 404 to drive the electric boiler body 1 located on the inner side of the resistance arc plate 405 to rotate, so that the electric boiler body 1 can also be rotated at an angle after completing the lifting process, thereby avoiding the need to repeatedly disassemble and reposition the boiler when inspecting the surface of the boiler, thereby achieving the effect of facilitating the maintenance of the electric boiler.

[0025] Specifically, a guide plate 304 is fixedly connected to a side end of the contact plate 305 , and the guide plate 304 is slidably connected to an inner wall of the driving box 301 .

[0026] In this embodiment, the guide plate 304 can move along with the contact plate 305 , so that the movement stability of the contact plate 305 is significantly improved.

[0027] Specifically, the transmission structure 403 includes a transmission motor and a transmission shaft. The transmission motor and the transmission shaft are connected via a transmission belt. The transmission motor and the transmission shaft are fixedly connected to two driving roller shafts 404 respectively.

[0028] In this embodiment, the transmission motor causes the transmission shaft to rotate synchronously through the transmission belt, so that the transmission motor and the transmission shaft jointly drive the two driving rollers 404 to perform synchronous transmission, so that the driving rollers 404 begin to drive the electric boiler body 1 to rotate on the inner side of the resistance arc plate 405.

[0029] Specifically, a resistance box 408 is fixedly connected to the outer side of the resistance arc plate 405, a damping spring rod 409 is arranged inside the resistance box 408, and the other end of the damping spring rod 409 is fixedly connected to a limit plate 410, and the limit plate 410 overlaps the end of the electric boiler body 1.

[0030] In this embodiment, the damping spring rod 409 arranged inside the contact box 408 can drive the limit plate 410 to automatically and adaptively clamp the end of the electric boiler body 1, so that the electric boiler body 1 is restricted between the two limit plates 410, thereby improving the clamping effect of the electric boiler body 1.

[0031] When in use, the electric boiler body 1 to be repaired is first placed in the rotating lifting structure 4, so that the two abutting arc plates 405 and the two driving rollers 404 lift the bottom of the electric boiler body 1, and then the limiting arc plate 406 is rotated so that the electric boiler body 1 is restricted inside the abutting arc plate 405;

[0032] In combination with the damping spring rod 409 disposed inside the abutment box 408, the limit plate 410 can be driven to automatically and adaptively clamp the end of the electric boiler body 1, so that the electric boiler body 1 is restricted between the two limit plates 410;

[0033] When it is necessary to complete the rotation of the electric boiler body 1 after clamping, the transmission structure 403 is started, so that the transmission motor drives the transmission shaft to rotate synchronously through the transmission belt, so that the transmission motor and the transmission shaft jointly drive the two driving rollers 404 to perform synchronous transmission, so that the driving rollers 404 start to drive the electric boiler body 1 to rotate on the inner side of the abutting arc plate 405;

[0034] When it is necessary to transfer the clamped electric boiler body 1, the mobile base 2 is pushed so that the mobile base 2 drives the electric boiler body 1 to move. When it is necessary to position the transferred electric boiler body 1, the positioning structure 3 is started so that the built-in motor inside the drive box 301 starts to drive the threaded rod 302 to rotate. Since the threaded block 303 is provided with a screw hole that matches the threaded rod 302, and the side of the contact plate 305 is slidably connected to the inner wall of the drive box 301 through the guide plate 304, the rotation of the threaded rod 302 will drive the threaded block 303 to move in the axial direction, so that the threaded block 303 will drive the contact plate 305 to gradually contact the ground, so that the contact plate 305 gradually lifts the mobile base 2 off the ground, so that the device can be stably placed in the current position after moving to the specified position.

[0035] In summary, the electric boiler which is easy to maintain, by setting a positioning structure 3, can use the built-in motor inside the drive box 301 to drive the threaded block 303 to drive the guide plate 304 through the threaded rod 302, so that the contact plate 305 gradually contacts the ground, so that the contact plate 305 gradually lifts the movable base 2 off the ground, so that the device can be stably placed in the current position after moving to the specified position, thereby avoiding the self-sliding situation in the comparison scheme, making the electric boiler more stable during daily maintenance; by setting a rotating lifting structure 4, the transmission chain structure can be used to cause the driving roller 404 to drive the electric boiler body 1 located on the inner side of the contact arc plate 405 to rotate, so that the electric boiler body 1 can also be rotated at an angle after completing the lifting process, thereby avoiding the need to repeatedly disassemble and reposition the boiler when inspecting the surface of the boiler, thereby achieving the effect of facilitating the maintenance of the electric boiler.
