Description

Technical Field

[0001] The utility model belongs to the technical field of cloth bag extractors, and in particular relates to a handheld cloth bag extractor. Background Art

[0002] In order to meet the national flue gas emission standards, thermal power plants are equipped with desulfurization devices. The core component of the desulfurization island dust collector is the bag. When inspecting and replacing the dust collector bag, the bag is currently taken out of the raft by manual methods, and then manually rolled and transported out of the dust collector cabin.

[0003] In order to save time in extracting bags, save manpower, improve work efficiency, and reduce the harm of quicklime to the human body, the existing petrochemical company's self-owned power plant has developed a handheld bag extractor that can clamp and reel the bags of the dust collector in one go, greatly improving work efficiency.

[0004] However, the existing handheld cloth bag extractor also has certain shortcomings. The existing handheld cloth bag extractor uses a servo motor to drive the baffle to rotate, so as to drive the clamping rod to rotate. Due to the problem that the output shaft of the servo motor is too long, the output shaft is prone to shaking and offset after long-term use, which makes the baffle rotate poorly. Summary of the invention

[0005] The purpose of the utility model is to provide a handheld cloth bag extractor, which solves the problem that the existing handheld cloth bag extractor uses a servo motor to drive the baffle to rotate, so as to drive the clamping rod to rotate. Due to the problem that the output shaft of the servo motor is too long, the output shaft is prone to shaking and offset after long-term use, thereby causing the baffle to rotate poorly.

[0006] In order to achieve the above-mentioned purpose, the utility model provides a handheld cloth bag extractor, including a base, the upper end of the base is fixedly connected to a bracket, the upper end of the bracket is fixedly connected to a fixed cylinder, a servo motor is fixedly installed on the inner right wall of the fixed cylinder, a rotating column is fixedly sleeved on the outer side of the output shaft of the servo motor, a limiting ring groove is provided on the surface of the rotating column, a guide plate is slidably connected to the inside of the fixed cylinder, a limiting ball is fixedly connected to the end face of the guide plate close to the rotating column, the limiting ball is slidably connected to the limiting ring groove, the output shaft of the servo motor is fixedly connected to a baffle, the baffle is rotatably connected to the fixed cylinder, and a clamping mechanism is provided on the baffle.

[0007] The principle of the utility model is: start the micro motor to drive the output end to rotate, so as to drive the bevel gear 2 to rotate. Under the meshing relationship, the bevel gear 2 drives the bevel gear 1 to rotate, and then drives the rotating shaft to rotate, so as to drive the positive and negative threaded screw rods to rotate. Under the relationship of threaded connection, the two sliders can be driven to move toward each other, and then drive the clamping rod to move, so as to automatically clamp the dust collector bag inside the desulfurization island;

[0008] Start the servo motor to drive the output shaft to rotate, so as to drive the baffle to rotate, and then drive the clamping rod to rotate, and reel up the dust collector bag. During this process, the servo motor drives the output shaft to rotate, so as to drive the rotating column to rotate, so that the limit ball slides along the inner wall of the limit ring groove, and the rotating column is limited to avoid the problem of shaking of the servo motor's over-long output shaft. Under the deformation action of the elastic sheet, the limit ball can be pushed to always contact with the inner wall of the limit ring groove, so as to avoid the wear problem of the limit ball and ensure the limiting effect of the limit ball and the limit ring groove.

[0009] The beneficial effect of the utility model is that the scheme can drive the positive and negative threaded screws to rotate through the coordinated use of micro motors, bevel gear 2, bevel gear 1 and other structures. Under the relationship of threaded connection, the two sliders can be driven to move toward each other, thereby driving the clamping rod to move, and finally automatically clamping the dust collector bags inside the desulfurization island. Through the coordinated use of servo motors, baffles and other structures, when the servo motor drives the output shaft to rotate, the clamping rod can be driven to rotate, thereby extracting and reeling the dust collector bags in one operation. Under the action of limit ring grooves, limit balls, elastic sheets and other structures, the rotating column can be limited in rotation, thereby limiting the output shaft of the servo motor, thereby avoiding the problem of jitter of the output shaft that is too long.

[0010] Furthermore, a friction groove is provided on the surface of the fixed cylinder, and a plurality of the friction grooves are provided. The plurality of friction grooves are evenly distributed on the fixed cylinder. The provision of the friction grooves facilitates the operator to hold and use the fixed cylinder.

[0011] Furthermore, two rotating columns are provided, and the two rotating columns are evenly distributed on the output shaft of the servo motor. The provision of the rotating columns facilitates subsequent use with structures such as a limit ball to reduce the jitter problem of the output shaft of the servo motor.

[0012] Furthermore, an elastic sheet is fixedly connected to the side of the limiting ball away from the rotating column, and the other end of the elastic sheet is fixedly connected to the fixing tube. The limiting ball can be tightened by the setting of the elastic sheet.

[0013] Furthermore, the clamping mechanism includes a rotating shaft, the interior of the baffle plate is rotatably connected to the rotating shaft, the outer side of the rotating shaft is fixedly sleeved with a bevel gear 1, the interior of the baffle plate is provided with a positive and negative threaded screw rod through a bearing, the positive and negative threaded screw rod is fixedly connected to the rotating shaft, the outer side of the positive and negative threaded screw rod is threadedly connected to two symmetrically distributed sliders, each of the sliders is slidably connected to the baffle plate, and a micro motor is fixedly installed on the right end of the baffle plate, the output end of the micro motor is rotatably connected to the baffle plate, and the output end is driven by the micro motor to rotate to drive the bevel gear 2 to rotate, and in the meshing relationship, the bevel gear 2 drives the bevel gear 1 to rotate, and then drives the rotating shaft to rotate, so as to drive the positive and negative threaded screw rod to rotate, and in the threaded connection relationship, the two sliders can be driven to move toward each other, and then drive the clamping rod to move, so as to automatically clamp the dust collector bag inside the desulfurization island.

[0014] Furthermore, the left end of each of the sliding blocks is fixedly connected with a clamping rod, and the clamping rod is slidably connected to the baffle plate. Through the setting of the clamping rod, the bag of the dust collector can be clamped.

[0015] Furthermore, a bevel gear 2 is fixedly sleeved on the outer side of the output end of the micro motor, and the bevel gear 2 is meshed with the bevel gear 1. Through the meshing relationship, when the bevel gear 2 rotates, it can drive the bevel gear 1 to rotate, thereby driving the forward and reverse threaded screw rods to rotate.

The interior of the baffle plate 10 is provided with a positive and negative threaded screw rod 113 through a bearing, and the positive and negative threaded screw rod 113 is fixedly connected to the rotating shaft 111. The outer side of the positive and negative threaded screw rod 113 is connected to two symmetrically distributed sliders 114 through threads, and each slider 114 is slidably connected to the baffle plate 10.
