Technical Field

[0001] This utility model relates to the field of hydraulic support technology, specifically a combined top beam hydraulic support. Background Technology

[0002] Hydraulic supports are hydraulic power devices that use liquid pressure to generate supporting force and achieve automatic relocation for roof support and management. They are an indispensable supporting equipment for fully mechanized coal mining, with the mining face pressure acting as an external load on the hydraulic supports.

[0003] In the existing technology, conventional hydraulic supports for roof beams lack mobility, resulting in unsmooth movement of the hydraulic supports. During use, it is impossible to monitor the support pressure, which poses a safety hazard. Furthermore, it is impossible to adjust the support points according to the needs of the support location, which can easily cause collisions with other equipment on the roadway roof, making it impossible for the hydraulic supports to provide effective support.

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.

[0020] Please see Figures 1-4 This utility model discloses a combined top beam hydraulic support, including a base 1. A drive mechanism 2 is fixedly installed between the front and rear inner walls of the base 1 near the left and right sides. Rollers 3 are fixedly installed in a rectangular shape at the four corners of the lower surface of the drive mechanism 2, and a first rectangular opening 4 is opened on the lower side wall of the base 1 corresponding to the rollers 3. The base 1 is hinged to the top beam 6 through two sets of first hydraulic telescopic rods 5. A front beam 7 is hinged to the left side of the top beam 6, and the front beam 7 is connected to the top beam 6 through a second hydraulic telescopic rod 8. A pressure detection mechanism 9 is provided in both the top beam 6 and the front beam 7, and a support mechanism 10 is provided on the upper surface of the pressure detection mechanism 9. A shield beam 11 is hinged to the right side of the top beam 6, and the lower end of the shield beam 11 is hinged to the base 1 through a connecting rod assembly 12.

[0021] Specifically, the drive mechanism 2 includes a bearing assembly 201, a ball screw 202, a ball nut 203, a rectangular plate 204, a hinge 205, and a transmission rod 206. The ball screw 202 is mirror-mounted on the front and rear side walls of the base 1 via the bearing assembly 201, and the facing sides of the front and rear ball screws 202 are fixedly connected. Each ball screw 202 is provided with a ball nut 203. A hinge 205 is provided between the lower surface of the ball nut 203 and the upper surface of the rectangular plate 204, and the upper and lower hinges 205 are connected by the transmission rod 206. The lower surface of the rectangular plate 204 is fixedly connected to the upper surface of the roller 3.

[0022] In this embodiment, the front and rear ball screws 202 rotate within the bearing assembly 201, causing the front and rear ball screws 202 to drive the ball nuts 203 to move back and forth. The front and rear ball nuts 203 drive the transmission rod 206 to move through the upper hinge 205, causing the transmission rod 206 to drive the rectangular plate 204 to move up and down through the lower hinge 205, causing the rectangular plate 204 to drive the roller 3 to move up and down. Both ends of the front and rear ball screws 202 are provided with internal hexagonal holes to facilitate the rotation of the ball screws 202 by an internal hexagonal wrench.

[0023] Specifically, a reinforcing plate 13 is fixedly installed between the front and rear inner walls of the base 1, and the lower surface of the reinforcing plate 13 is movably fitted with the upper surface of the ball nut 203. The outer surface of the ball nut 203 has a rectangular structure.

[0024] In this embodiment, the reinforcing plate 13 limits the upper surface of the ball nut 203, giving the ball nut 203 greater strength and making it less prone to damage.

[0025] Specifically, the front and rear sides of the rectangular plate 204 are movably fitted with the front and rear inner walls of the base 1.

[0026] In this embodiment, the front and rear sides of the rectangular plate 204 move up and down along the front and rear inner walls of the base 1, making the up and down movement of the rectangular plate 204 more stable.

[0027] Specifically, the pressure detection mechanism 9 includes a mounting plate 901, a pressure sensor 902, a second rectangular opening 903, and an alarm 904. The mounting plate 901 is fixedly installed between the front and rear inner walls of the top beam 6. The pressure sensor 902 is uniformly fixedly installed on the upper surface of the mounting plate 901, and the pressure sensor 902 extends out of the upper side wall of the top beam 6. The second rectangular opening 903 is opened on the upper side wall of the top beam 6 corresponding to the pressure sensor 902. The alarm 904 is installed on the front and rear sides of the top beam 6.

[0028] In this embodiment, the mounting plate 901 is used to install the pressure sensor 902. The pressure sensor 902 monitors the support pressure of the support mechanism 10. When the pressure sensor 902 detects that the support pressure of the support mechanism 10 is too high, the alarm 904 will sound an alarm to remind the staff.

[0029] Specifically, the support mechanism 10 includes a slide plate 101, a support block 102, a threaded hole 103, and a locking bolt 104. The slide plate 101 is fixedly installed on the upper surface of the pressure sensor 902. The support block 102 is movably installed on the slide plate 101. Threaded holes 103 are provided on the front and rear sides of the slide plate 101 and on the support block 102. The slide plate 101 and the support block 102 are locked and fixed together by the locking bolt 104.

[0030] In this embodiment, the locking bolt 104 installs the support block 102 into the threaded hole 103 at different positions, thereby achieving the effect of adjusting the left and right positions of the support block 102, and supporting the top of the tunnel through the support block 102 on the slide plate 101.

[0031] In use, the front and rear ball screws 202 in the drive mechanism 2 rotate within the bearing assembly 201, causing the ball screws 202 to drive the ball nuts 203 to move back and forth. The ball nuts 203, through the upper hinge 205, drive the transmission rod 206 downward, causing the transmission rod 206, through the lower hinge 205, to drive the rectangular plate 204 downward, causing the rectangular plate 204 to drive the roller 3 downward, so that the lower surface of the roller 3 is lower than the lower surface of the base 1. This increases the mobility of the hydraulic support, making it easier and more stable to move. When the hydraulic support is moved to the desired position, the drive mechanism 2 drives the roller 3 to return to its original position. Then, based on the position of other equipment on the top of the tunnel, the support mechanism... The locking bolts 104 in section 10 install the support block 102 into the threaded holes 103 at different positions, achieving the effect of adjusting the left and right position of the support block 102 and preventing the support block 102 from colliding with other equipment. The first hydraulic telescopic rod 5 drives the top beam 6 to move upward. The top beam 6 drives the support block 102 on the slide plate 101 to move upward through the pressure detection mechanism 9, so that the support block 102 supports the top of the roadway. The pressure sensor 902 monitors the support pressure of the support mechanism 10. When the pressure sensor 902 detects that the support pressure of the support mechanism 10 is too high, the alarm 904 will sound an alarm to remind the staff, so that the problem of excessive pressure can be dealt with in a timely manner, making the use safer.

[0032] In summary, this combined top beam hydraulic support enhances the mobility of the hydraulic support, making it easier and more stable to move. It also allows for monitoring of the support pressure, enabling timely handling of excessive pressure issues, thus improving safety. Furthermore, it allows for adjustment of the support position, making support more convenient.
