Description

Technical Field

[0001] The utility model relates to the technical field of machine repair auxiliary equipment, and more specifically, to a kettle bottom bolt removal tool. Background Art

[0002] A reactor is a container used for physical or chemical reactions. Reactors are also widely used in the production of recycled textile materials. The bottom of the reactor is generally provided with a discharge port. During maintenance work on the reactor, the discharge port needs to be fully opened, which involves the removal of the bolts at the bottom of the reactor at the discharge port. The removal of the bolts at the bottom of the reactor is currently done manually. Due to the installation height of the reactor, the height difference between the bottom of the reactor and the ground is small, and there are also intricate pipes near the discharge port at the bottom of the reactor. Therefore, it is very difficult for mechanics to remove the bolts at the bottom of the reactor. Workers need to squat and look up for a long time during the disassembly operation. In addition, conventional wrenches and other tools are limited by the limited operating space at the bolt position (pipeline obstruction affects the use of wrenches), and are not easy to use. Every time the bolts at the bottom of the reactor are removed, more workers are required to cooperate with the operation, and the waste of labor and time is relatively serious. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1-Figure 3 The tool for removing bolts at the bottom of a reactor shown in the figure is used for removing bolts at the bottom of a reactor. The tool comprises a removal sleeve 1, an extension tube 2, a flat trolley 3 and an electric screwing device 5. The removal sleeve 1 is fixedly connected to one end of the extension tube 2. The removal sleeve 1 matches the size of the bolt to be removed. Before removing the bolt, the sleeve is first put on the bolt head. The space where the bolts at the bottom of the reactor are located is narrow, and there are various pipes on the side, which is not conducive to the direct use of the sleeve. The extension tube 2 has the effect of extending the length of the sleeve. The extension tube 2 can pass through the narrow area where the bolts at the bottom of the reactor are located and come to an open position close to the ground. A motor frame 4 is installed on the flat trolley 3. The electric screwing device 5 is installed on the motor frame 4. When using the utility model, the flatbed trolley 3 is pushed to the position below the bottom of the reactor, and the output end of the electric screwing device 5 is connected to the other end of the extension tube 2. After turning on the electric screwing device 5, the extension tube 2 can be used to drive the removal sleeve 1 to rotate, so as to achieve the purpose of removing the bolts at the bottom of the reactor. During the application of the utility model, the worker only needs to complete the docking of the removal sleeve 1 and the bolt, and the docking operation of the electric screwing device 5 and the extension tube 2. The removal of the bolts is completed by electric power, which makes the bolt removal operation labor-saving and efficient. Under normal circumstances, a single mechanic can complete the bolt removal operation.

[0022] like Figure 1 As shown, a plurality of running wheels 31 with braking function are installed at the bottom of the flatbed trolley 3. The design of the running wheels 31 enables the flatbed trolley 3 to move freely. The worker can directly pull the flatbed trolley 3 to move to the position below the bottom of the kettle. The running wheels 31 have a built-in braking function. After braking, the flatbed trolley 3 stops on the ground, and the bolt removal operation can be carried out at this time.

[0023] like Figure 1As shown, the motor frame 4 includes a rotating seat 41, a vertical frame 42 and a horizontal frame 43. The rotating seat 41 is rotatably connected to the plate surface of the flatbed trolley 3, and the vertical frame 42 is fixedly connected to the rotating seat 41. The vertical frame 42 is installed upright, and one end of the horizontal frame 43 is hingedly connected to the vertical frame 42, and the horizontal frame 43 is connected to the top of the vertical frame 42. The horizontal frame 43 can be flipped up and down relative to the vertical frame 42. The electric screwing device 5 is fixedly installed on the horizontal frame 43 and can move with the horizontal frame 43. Since the rotating seat 41 can rotate in a plane and cooperate with the flipping movement of the horizontal frame 43, the electric screwing device 5 can achieve multi-directional movement to facilitate its docking with the extension tube 2 (the installation position of the bottom bolt of the kettle has high and low positions, and there are also changes in angles. The extension tube 2 is a straight tube, which is equivalent to an extension of the bolt. Therefore, solving the docking of the electric screwing device 5 with the extension tube 2 in different directions and positions is a difficult problem).

[0024] like Figure 2 As shown, a handle 431 is connected to the side wall of the horizontal frame 43. There are two handles 431, which are symmetrically arranged. The handle 431 plays a role of hand-held operation. A worker holding the handle 431 can drive the horizontal frame 43 and the electric screwing device 5 to adjust the direction.

[0025] like Figure 1 As shown, the electric screwing device 5 includes a screwing motor 51 and a universal connecting sleeve 52. The screwing motor 51 is fixedly installed on the horizontal frame 43. The screwing motor 51 moves with the horizontal frame 43. The extension tube 2 is connected with a polygonal joint 21. One end of the universal connecting sleeve 52 can be matched and connected to the polygonal joint 21, and the other end of the universal connecting sleeve 52 can be matched and connected to the output end of the screwing motor 51. The screwing motor 51 adopts a low-speed, high-torque motor. The universal connecting sleeve 52 plays a role in power transmission. The universal connecting sleeve 52 can transmit power in the case of non-linear connection. The universal connecting sleeve 52 is a product purchased on the market and will not be introduced here. After the screwing motor 51 is started, the torque is transmitted to the extension tube 2 and the removal sleeve 1 through the universal connecting sleeve 52, thereby acting on and unscrewing the bottom bolts of the kettle. A battery pack 32 is installed on the flatbed trolley 3. The screwing motor 51 is powered by the battery pack 32. The battery pack 32 is rechargeable and should be charged before use.

[0026] like Figure 3 As shown, the removal sleeve 1 and the extension tube 2 are connected by threaded fixing, so as to facilitate the disassembly and separation of the two. This is because the bottom bolts of the kettle may have different specifications, so different removal sleeves 1 are required for disassembly. The threaded connection design facilitates the replacement operation of the removal sleeve 1. Two symmetrically arranged clamping notches 22 are provided on the outer wall of the extension tube 2. When disassembling, the extension tube 2 is clamped on a bench vise, and the clamping notch 22 is designed for clamping and fixing the extension tube 2.

[0027] like Figure 3 As shown, a through rod insertion hole 23 is provided on the extension tube 2, and the rod insertion hole 23 is provided at the end close to the polygonal joint 21. A booster rod 24 can be inserted into the rod insertion hole 23, and the extension tube 2 can be driven to rotate directly by pushing the booster rod 24. At this time, it is a manual bolt removal operation. When the flatbed trolley 3 cannot be pushed into place, a manual bolt removal operation can be adopted. Sometimes the bolts are tightly engaged, and the screwing motor 51 cannot screw the bolts all at once. At this time, the booster rod 24 can be inserted first, and then the booster rod 24 can be hammered to loosen the bolts. After loosening, the electric screwing device 5 can be connected to remove the bolts electrically.

[0028] When the utility model is used, first fix a suitable removal sleeve 1 to the extension tube 2, then put the removal sleeve 1 on the bolt head, pull the flatbed trolley 3 to the vicinity of the operating position, connect one end of the universal connection sleeve 52 to the extension tube 2, flip the horizontal frame 43 by hand, so that the other end of the universal connection sleeve 52 is connected to the electric screwing device 5, lock the brake of the flatbed trolley 3, and start the screwing motor 51 while holding the horizontal frame 43 to complete the bolt removal operation. This operation is convenient, efficient, and labor-saving. It can be performed by one person, which can greatly save time and labor.

[0029] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
