Description

Technical Field

[0001] The present invention relates to the technical field of boiler maintenance, and specifically to a boiler rope retractor. Background Art

[0002] The two circulating fluidized bed boilers of Beijing Energy (Chifeng) Development Co., Ltd. are 2×UG-480 / 13.7-M circulating fluidized bed boilers designed and manufactured by Wuxi Huaguang Boiler Factory. The #1 and #2 boilers are equipped with 8 φ22 maintenance platform safety ropes respectively. At least 8 maintenance personnel are required to pull and release each safety rope. Not only is the workload and work intensity high, but there are also safety hazards such as loose wires and people being wound. In recent years, the country has gradually strengthened production safety management and emphasized the importance of safety. At present, this work of collecting and releasing safety ropes entirely by manpower can no longer adapt to the current production safety situation.

[0003] Each boiler of Beijing Energy (Chifeng) Energy Development Co., Ltd. is equipped with 8 φ22 maintenance platform safety ropes, which are hung on the boiler roof steel beam respectively. This end is the fixed end. If one end of the safety rope is fixed on the winding shaft, the winding shaft can be used to carry out the safety rope retraction and release work, but the fixity and reliability of the winding shaft are quite different from those of the boiler steel beam, which does not meet the safety rope fixation requirements.

[0004] However, currently neither power generation companies nor the market have dedicated reeling products, which is not conducive to the placement of safety ropes and has high maintenance and overhaul costs. Summary of the invention

[0005] The object of the present invention is to provide a boiler rope retractor in order to solve the above-mentioned problems.

[0006] The technical solution adopted by the present invention is as follows: a boiler rope collector, comprising a supporting base plate, a supporting frame welded to the upper surface of the supporting base plate, a reference platform welded to the upper surface of the supporting frame, a movable groove is provided on the upper surface of the reference platform, a threaded hole is provided on the inner surface of the reference platform, a support seat is movably connected to the inner surface of the movable groove, a hexagonal screw is movably connected to the outer surface of the support seat, and the outer surface of the hexagonal screw passes through the support seat and is fixedly installed on the threaded hole.

[0007] By adopting the above technical solution, the support base plate serves as the main support platform of the equipment. It may be a thick iron plate or a concrete placement table. It is installed according to actual conditions. The support frame is convenient for supporting the base table. The base table supports the placement of the support seat. The support seat is movable left and right in the movable groove and is fixed in the corresponding position by hexagonal screws. The load-bearing shaft is fixed on both sides, and the bearings ensure the rotation effect.

[0008] In a preferred embodiment, a bearing is disposed on the inner surface of the support seat, and a force-bearing shaft is disposed on the inner surface of the bearing.

[0009] By adopting the above technical solution, the bearing facilitates the rotation of the force-bearing shaft, and then when the driven wheel and the driving wheel are clamped and reeled, the force-bearing shaft completes the rotation under the premise of stable support.

[0010] In a preferred embodiment, a driven wheel is welded to the middle outer surface of the force-bearing shaft, and a fastening sleeve is fixedly connected to the outer surface of the force-bearing shaft corresponding to the bearing.

[0011] By adopting the above technical solution, the outer diameter of the fastening sleeve is larger than the inner diameter of the bearing, so it is better stuck in the bearing, and the driven wheel can conveniently clamp the steel rope on the other side when the driving wheel rotates.

[0012] In a preferred embodiment, a reinforcing beam is fixedly connected to the upper surface of the support base plate, and a mounting base is fixedly connected to the upper surface of the reinforcing beam.

[0013] By adopting the above technical solution, the installation base is convenient for the installation and placement of the reeling machine, and the reinforcing beam is reinforced at the bottom. If the machine placed above is too heavy, the downward pressure will cause irreversible deformation of the concrete slab.

[0014] In a preferred embodiment, a raised platform is provided on the upper surface of the mounting base, and a motor is fixedly connected to the upper surface of the raised platform.

[0015] By adopting the above technical solution, the pad is raised to provide support at one end, and the motor is placed in the air, and the motor provides mechanical power for the winding of the steel rope.

[0016] In a preferred embodiment, the outer surface of the motor is fixedly connected to the reducer housing, the outer surface of the motor output end is fixedly connected to the input shaft, the outer surface of the input shaft is welded with a planetary gear shaft, and the outer surface of the planetary gear shaft is meshingly connected to the output shaft.

[0017] By adopting the above technical solution, the motor drives the input shaft to rotate, and then drives the planetary gear shaft to rotate. The gears on the periphery of the planetary gear shaft mesh with the inner gear ring of the outer ring to rotate, and the output is output by the output shaft, which reduces the rotation speed and increases the torque.

[0018] In a preferred embodiment, a brake body is disposed on the outer surface of the output shaft, and a driving wheel is welded to the outer surface of the brake body.

[0019] By adopting the above technical solution, the brake body is opened when power is on, which facilitates the rotation of the driving wheel. When power is off, the brake is fixed to avoid safety hazards caused by rapid displacement of the driving wheel.

[0020] In a preferred embodiment, an adjustment frame is movably connected to the lower surface of the reference platform, and an auxiliary roller is movably connected to the lower surface of the adjustment frame.

[0021] By adopting the above technical solution, the adjustment frame can be rotated at the reference table to facilitate angle adjustment, thereby finding the middle position between the driven wheel and the driving wheel, facilitating the placement of the steel rope, and the rolling of the auxiliary roller can better guide the steel rope when it is retracted and released.

[0022] In a preferred embodiment, a fixing seat is welded to the upper surface of the support base plate, and a reinforcing plate is welded to the outer surface of the fixing seat.

[0023] By adopting the above technical solution, the fixing seat and the reinforcing plate facilitate the support of the limit frame and ensure the entry of the steel rope.

[0024] In a preferred embodiment, the outer surface of the fixing seat is fixedly connected to a limiting frame, and the inner surface of the fixing seat is rotatably connected to a rope feeding roller.

[0025] By adopting the above technical solution, the upper surface of the rope feeding roller contacts the steel rope, and the steel rope is guided into the equipment by rotation. The limit frame is convenient for limiting, thereby preventing the steel rope from falling off.

[0026] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. The equipment moves left and right in the movable groove through the support seat, and is fixed in the corresponding position by hexagonal screws. The displacement of the support seat completes the adjustment of the distance between the driven wheel and the driving wheel, thereby facilitating the extrusion and retraction of steel ropes with different radii; Second, a control box can be connected and expanded through the circuit. The operator can operate the local control box to realize the forward and reverse rotation of the motor to drive the V-shaped wheel to rotate, realize the wire rope collection and release work, and complete the wire rope collection and release work more efficiently; 3. Only two persons are needed to collect and release the wire rope, one to operate the control box and the other to monitor the rope winding. BRIEF DESCRIPTION OF THE DRAWINGS

Under the action of the adjustment frame 21, the angle is adjusted conveniently, and then the middle position between the driven wheel 10 and the driving wheel 20 is found. The position of the driving wheel 20 is fixed, and the support seat 6 moves left and right at the movable groove 5, and is fixed in the corresponding position by the hexagonal screw 7. The force-bearing shaft 9 is fixed on both sides, and the bearing 8 ensures the rotation effect. The tightening sleeve 27 increases the mechanical force to ensure stability. The distance between the driven wheel 10 and the driving wheel 20 is adjusted by adjusting the displacement of the support seat 6, so as to facilitate the extrusion and release of steel ropes with different radii. By turning on the motor 14 to provide mechanical kinetic energy for rope collection, the planetary reduction of the reducer housing 15 increases the torque, which drives the rotation of the driving wheel 20. The rotation of the driving wheel 20 and the driven wheel 10 drives the steel rope to be extruded upward to complete the rope collection.
