The casing head is generally installed using a connecting flange and locking bolts.

[0003] The existing installation equipment mainly uses electric drill bits to tighten the locking bolts. The main advantage of using electric drill bits to install sleeve heads is that it is efficient and convenient to operate. It can quickly and evenly tighten the locking bolts, greatly improve construction efficiency, reduce manpower requirements and reduce fatigue. For example, it can precisely control the torque, ensure the stability and sealing of the flange connection, and avoid the errors and time waste of manual installation.

[0004] However, this device has safety defects. Since the drill bit will always rotate after the start switch is pressed, and there is no additional safety structure, the rotation of the drill bit when accidentally activated may cause a safety accident. Therefore, a casing head installation device is proposed to solve the above problems. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 The sleeve head installation device in this embodiment includes a housing 1, a gripping component 2 for easy gripping by the user at the bottom of the housing 1, a ventilation plate 3 fixedly connected to the left side of the housing 1, a drive mechanism 4 for providing power for installation on the inner side of the housing 1, a protective component 5 located to the right of the drive mechanism 4 and providing protection on the inner side of the housing 1, and a transmission component 6 for transmitting power to the sleeve head bolt on the right side of the protective component 5.

[0024] In addition, the grip assembly 2 includes a handle 201 fixed to the bottom of the housing 1. The handle 201 and the tray 203 cooperate to improve the stability of the device and make it easier for the user to hold the device. A button 202 located on the right side of the handle 201 is fixed to the bottom of the housing 1. The button 202 is used to control the drive mechanism 4. The tray 203 is also fixed to the bottom of the housing 1. Multiple grip grooves are provided on both the handle 201 and the tray 203. The grip grooves can fit the fingers better, thereby improving the stability and comfort of the grip. A battery is provided on the inside of the handle 201. A baffle is fixed to the bottom of the handle 201 by bolts. The baffle is used to block the battery and prevent the battery from falling out accidentally.

[0025] In addition, the ventilation plate 3 has multiple ventilation holes and is stepped. The stepped ventilation plate 3 can improve the stability of the ventilation plate 3 and reduce the tangential load on the fixing bolts. The ventilation plate 3 is threaded with multiple fixing bolts and is fixed to the outer shell 1 by the fixing bolts. The drive mechanism 4 includes a drive motor 401 and a reducer 402 fixed to the inner wall of the outer shell 1. One end of the output shaft of the drive motor 401 is fixed to the input end of the reducer 402.

[0026] In this embodiment, the ventilation plate 3 can improve heat dissipation, thereby effectively cooling the drive motor 401. In addition, the ventilation plate 3 itself is easy to disassemble. When it is necessary to maintain the drive motor 401, the ventilation plate 3 can be directly removed.

[0027] Please refer to it again. Figures 1 to 3 To prevent accidental activation and improve safety, the protective component 5 in this embodiment includes a stabilizing cylinder 502 fixed to the inner wall of the outer shell 1. A meshing plate 501 is fixed to the right side of the drive mechanism 4. Through the cooperation of the meshing plate 501 and the telescopic part 506, the transmission and interruption of power can be controlled, thereby achieving a good protective effect. The inner side of the stabilizing cylinder 502 is rotatably connected to the protective shell 503 through a bearing. An electric push rod 504 is fixed to the inner right wall of the protective shell 503. A safety switch is provided at the top of the outer shell 1. The electric push rod 504 is controlled by the safety switch, thereby indirectly controlling the telescopic part 506. A storage tube 505 is fixed to the inner left wall of the protective shell 503. The storage tube 505 is filled with hydraulic oil. The electric push rod 504 extends into the storage tube 505. The storage tube 505 is provided with a telescopic part 506 that can extend to the outside of the protective shell 503.

[0028] Understandably, a piston is fixed to the left side of the electric push rod 504 and inside the storage tube 505. Multiple sealing rings are fixed to the outer surface of the piston. The piston and sealing rings work together to improve the sealing performance of the piston, thereby better driving the hydraulic oil. The output end of the reducer 402 is fixed to the meshing plate 501. The reducer 402 can increase the torque by reducing the speed.

[0029] It should be further explained that the telescopic part 506 includes a disc 5065 that is fixedly connected to the outer surface of the storage tube 505. The outer surface of the disc 5065 has a plurality of stepped holes 5061 that communicate with the storage tube 505. The stepped holes 5061 are used to provide the necessary space for the connecting spring 5062 and the moving tooth 5063. A connecting spring 5062 is fixed to the inner bottom wall of each stepped hole 5061, and an extension extending to the disc 5065 is fixed to the other side of each connecting spring 5062. The external moving teeth 5063, each stepped hole 5061 has a sealing ring 5064 fixed inside, the sealing ring 5064 plays a sealing role. The moving teeth 5063 itself fits against the inner wall of the stepped hole 5061, but in order to further prevent hydraulic oil leakage, the sealing ring 5064 is used to further improve the sealing performance. The inner side of the sealing ring 5064 abuts against the moving teeth 5063. The inner side of the meshing plate 501 is provided with multiple internal teeth, and the multiple internal teeth are adapted to the multiple moving teeth 5063.

[0030] In addition, the transmission assembly 6 includes a rotating rod 601 fixed to the right side of the protective shell 503 and extending outside the outer shell 1. The transmission assembly 6 also includes two connecting flanges 602 and multiple connecting bolts 603. The two connecting flanges 602 are fixed by multiple connecting bolts 603. The left connecting flange 602 is fixed to the rotating rod 601, and the right connecting flange 602 is fixed to the mounting accessories. The mounting accessories can be hexagonal socket heads or grinding heads, as long as they meet the installation requirements.

[0031] In this embodiment, the two connecting flanges 602 and the connecting bolts 603 work together to facilitate the replacement of the installation accessories, and the power transmission is controlled by the protection component 5, thereby improving the overall safety.

[0032] Understandably, the combination of drive mechanism 4, protection component 5 and transmission component 6 can reduce the occurrence of accidental touches. When protection component 5 is turned off, if button 202 is pressed, the rotating rod 601 will not rotate, making it safer to use.

[0033] All electrical components mentioned in this article are electrically connected to the controller and power supply. The control method of this utility model is controlled by the controller. The control circuit of the controller can be implemented by those skilled in the art through simple programming. The power supply provided by the storage battery is also common knowledge in the field. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0034] The working principle of the above embodiments is as follows:

[0035] When installation is required, first replace the installation accessories with the appropriate ones according to the installation requirements. Then, control the extension of the electric push rod 504 to move the liquid in the storage tube 505 into the disc 5065. At this time, due to the hydraulic action, the moving gear 5063 will move outward and engage with the meshing plate 501. Then, the user holds the handle 201 and, if necessary, can use the other hand to support the support plate 203. Then, press the button 202. At this time, the power of the drive motor 401 will be transmitted to the protection component 5 through the reducer 402 and further transmitted to the transmission component 6 to achieve the tightening of the bolts. When it is necessary to grind the uneven surface, the connecting bolt 603 can be unscrewed and the grinding head can be replaced to grind the uneven surface.
