Abstract
Description
Technical Field
[0001] The utility model relates to the field of compressor crosshead fastening, and specifically relates to a reciprocating compressor crosshead nut fastening impact wrench. Background Technique
[0002] During the maintenance of chemical enterprises, one of the commonly used maintenance tools is an impact wrench, which is suitable for occasions where the working space is narrow and ordinary wrenches cannot be used. It is often used to screw out hexagon head bolts or nuts.
[0003] When fastening the crosshead of a compressor, it is necessary to tighten the connecting nut of the crosshead (as Figure 3 shown). When using an impact wrench for fastening, the existing impact wrench used is an open-end fixed wrench (as Figure 4 shown, it is not necessary to remove the equipment connecting parts when using this fixed wrench). The open-end fixed wrench is inserted into the connecting nut of the compressor crosshead for fastening. However, although the impact fixed wrench can achieve fastening, after being used several times, the opening angle of the fixed wrench is subjected to large force and it will be deformed and worn, and it cannot be used continuously. The overall usage frequency is low, which affects the fastening of the compressor crosshead. Content of the Utility Model
[0004] In order to solve the above existing problems, the utility model provides a reciprocating compressor crosshead nut fastening impact wrench.
[0005] The utility model is realized through the following technical solutions:
[0006] A reciprocating compressor crosshead nut fastening impact wrench includes an impact head and an impact handle that are integrally formed up and down. A plum blossom hole is opened inside the impact head, and an insertion port is opened on one side of the impact head. A connection tensioning component is arranged outside the insertion port.
[0007] Further optionally, the connection tensioning component includes insertion nuts fixed at the upper and lower ends of the insertion port and connection nuts. A connection screw rod screwed with the connection nuts is inserted into the insertion nuts.
[0008] Further optionally, corresponding connection rings are fixed on the outer sides of the end of the connection screw rod and the connection nut, and a connection spring is arranged between the two connection rings.
[0009] Further optionally, the connection spring is a tension spring and its two ends are connected and fixed to the connection rings through hooks.
[0010] Further optionally, the insertion nuts and the connection nuts are welded and fixed to the upper and lower parts of the insertion port of the impact head.
[0011] Compared with the existing technology, the beneficial effects of the present utility model are as follows: By providing a penetrating insertion port on the side of the plum blossom hole of the impact wrench and arranging a connection and tensioning assembly on the side of the insertion port for easy disassembly and assembly, the advantages of the impact plum blossom wrench and the impact open-end wrench are utilized to achieve the fitting of the fastening surface of the wrench and the nut plane, avoiding the trouble of disassembling the equipment during the installation process and extending the service life of the tool.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0017] The present utility model will be further described in detail below in conjunction with the drawings and the specific embodiments:
[0018] As Figure 1 shown, a reciprocating compressor crosshead nut fastening impact wrench includes an impact head 1 and an impact handle 2 integrated up and down. A plum blossom hole 3 is provided inside the impact head 1, and an insertion port 4 is provided on one side of the impact head 1. The open insertion port 4 facilitates the penetration of the connecting rod 11 of the compressor crosshead 10. A connection and tensioning assembly is provided outside the insertion port 4 to close the insertion port 4 through the connection and tensioning assembly, ensuring the uniformity of the force on the subsequent plum blossom hole 3 and avoiding deformation caused by uneven force on the insertion port 4.
[0019] As Figure 2 shown, the connection and tensioning assembly includes an insertion nut 6 and a connection nut 5 fixed at the upper and lower ends of the insertion port 4. The size of the insertion nut 6 is larger than that of the connection nut 5. It is only necessary to penetrate the connection screw rod 7 inside the insertion nut 6. The connection screw rod 7 inserted inside the insertion nut 6 is screwed with the connection nut 5, so that the connection screw rod 7 is connected quickly and efficiently.
[0020] As Figure 1As shown, corresponding connecting rings 8 are fixed to the outer sides of the ends of the connecting screw 7 and the outer side of the connecting nut 5. A connecting spring 9 is connected between the two connecting rings 8. By the tension restriction of the connecting spring 9, the connecting screw 7 is prevented from loosening under the vibration generated by high-frequency knocking, ensuring the closed connection of the insertion port 4.
[0021] As Figure 1 shown, the connecting spring 9 is a tension spring and its two ends are connected and fixed to the connecting ring 8 through hooks. The connection through hooks facilitates the disassembly and assembly of the connecting screw 7.
[0022] As Figure 1 shown, the insertion nut 6 and the connecting nut 5 are welded and fixed to the upper and lower parts of the insertion port 4 of the knocking head 1.
[0023] The implementation principle of a reciprocating compressor crosshead nut tightening knocking wrench in an embodiment of the present application is as follows:
[0024] When tightening the connecting nut 12 of the compressor crosshead 10, first unscrew and remove the connecting screw 7 from the connecting nut 5. Insert the insertion port 4 of the knocking head 1 into the connecting rod 11 on one side of the connecting nut 12, so that the plum blossom hole 3 of the knocking head 1 faces the side end of the connecting nut 12, and adjust the plum blossom hole 3 of the knocking head 1 to be stuck on the outer edge of the corresponding connecting nut 12.
[0025] Then install the connection tightening assembly. Insert the connecting screw 7 along the insertion nut 6 and screw it into the connecting nut 5 for connection. In this way, the connecting nut 5 plays a role in closing and tightening the insertion port 4. When subsequently rotating the knocking handle 2 to tighten the connecting nut 12 by knocking, the fitting surface of the plum blossom hole 3 of the knocking head 1 and the plane of the connecting nut 12 are in contact, avoiding the trouble of disassembling the equipment during the installation process, prolonging the service life of the tool, and the force is relatively uniform. At the same time, the open insertion port 4 will not be deformed and worn due to uneven force, ensuring the subsequent use of the knocking head 1.
[0026] After the knocking is completed, remove the knocking head 1 by disassembling and removing the connection tightening assembly. At the same time, during the knocking process, the tightened connecting spring 9 plays a role in restricting the loosening of the connecting screw 7, preventing the loosening of the front connecting screw 7 caused by the vibration generated when knocking the knocking handle 2, and ensuring the uniform force closure of the insertion port 4.
[0027] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
