Description

Technical Field

[0001] This utility model relates to the field of mine pressure gauge technology, and in particular to a hydraulic support mine pressure gauge fixing device. Background Technology

[0002] The hydraulic pressure gauge is an indispensable core monitoring instrument on the hydraulic support of the fully mechanized mining face. It can directly and in real time display the liquid pressure in the cavity of the support column. By observing and recording the reading of the pressure gauge, the operator can accurately judge whether the working status of the support is normal, thereby ensuring the safety of underground workers.

[0003] Most mine pressure gauges are currently suspended at a high position, making observation and maintenance inconvenient. They are also mostly exposed to the construction environment, making them susceptible to damage from flying coal and gangue, or their accuracy and lifespan may be affected by the damp and dusty environment underground.

[0004] Therefore, given that existing mine pressure gauges are installed at high positions and are easily damaged, a hydraulic support mine pressure gauge fixing device can be designed. This device can protect the mine pressure gauge by enclosing it and fixing it at a suitable height, effectively preventing damage to the mine pressure gauge from coal blocks and gangue during construction, extending the service life of the mine pressure gauge, facilitating intuitive observation of the dial reading, and enabling convenient maintenance operations, thereby effectively enhancing the practical value of the device. Utility Model Content

[0005] To overcome the problems that most mine pressure gauges are suspended at high positions, making observation and maintenance inconvenient, and are mostly directly exposed to the construction environment, which can easily affect their accuracy and lifespan, this utility model is proposed.

[0006] The technical solution of this utility model is as follows: a hydraulic support mine pressure gauge fixing device, including a device shell and a positioning hole opened at the front end of the device shell, and also including an installation component, an L-shaped top cover, an observation window, a locking component, an arc-shaped support plate and a moving component. The device shell is fixed to the outside of the hydraulic support by the installation component. The rear end of the device shell is hinged to an L-shaped top cover. The L-shaped top cover closes the device shell by the locking component. An observation window is provided on one side of the top plate of the L-shaped top cover. An arc-shaped support plate is provided on the bottom inner side of the device shell. The arc-shaped support plate is displaced by the moving component.

[0007] Preferably, the device housing is stably fixed to the designated position of the hydraulic support by setting the installation components. The installation position of the mine pressure gauge is determined by the positioning holes. The position of the arc-shaped support plate is flexibly moved by the moving components so that the arc-shaped support plate abuts against the bottom of the mine pressure gauge, ensuring the stability of the mine pressure gauge position. The L-shaped top cover is closed to enclose the mine pressure gauge inside the device housing. The L-shaped top cover is locked to the device housing by the locking components. The mine pressure gauge reading is directly observed through the observation window. This achieves the effect of protecting the mine pressure gauge, fixing it at a suitable height, extending the service life of the mine pressure gauge, facilitating direct observation of the dial reading, and enabling convenient maintenance operations, thereby enhancing the practical value of the device.

[0008] Preferably, the positioning hole corresponds to the installation position of the mine pressure gauge in the hydraulic support, the observation window corresponds to the position of the mine pressure gauge dial inside the device housing, and the top of the middle part of the arc-shaped support plate is set as an elastic pad with a certain elasticity.

[0009] Preferably, the mounting assembly includes a mounting lug and a first mounting hole. The mounting lugs are symmetrically arranged on both sides of the front end of the device housing. The mounting lugs are arc-shaped and their arc surfaces fit against the outer wall of the hydraulic support. A first mounting hole is provided on one side of the mounting lug. A bolt is screwed into the first mounting hole to fix the device housing in the mounting position.

[0010] Preferably, the mounting assembly also includes a second mounting hole. Two sets of second mounting holes are symmetrically provided on the inner front end of the device housing. Bolts are screwed into the second mounting holes to further fix the device housing in the mounting position.

[0011] Preferably, the locking component includes a third mounting hole and a mounting groove. The top plate of the L-shaped top cover is symmetrically provided with the third mounting hole on both sides, and the top of the device housing is symmetrically provided with two sets of mounting grooves. The mounting grooves correspond to the positions of the third mounting holes. The fasteners are screwed into the third mounting holes to tighten the L-shaped top cover.

[0012] Preferably, the moving component includes a T-shaped groove and a T-shaped slider. Two sets of T-shaped grooves are symmetrically opened on the bottom inner side of the device housing, and T-shaped sliders are symmetrically arranged on both sides of the bottom end of the arc-shaped support plate. The T-shaped sliders slide along the T-shaped grooves.

[0013] Preferably, an observation component is provided on the inner side of the top plate of the L-shaped top cover. The observation component includes a power supply and a ring light strip. A power supply is provided at the bottom of the L-shaped top cover, and a ring light strip is provided on the outer edge of the observation window. The power supply is a removable battery that powers the ring light strip.

[0014] The beneficial effects of this utility model are: When fixing the mine pressure gauge, securely fix the device casing to the designated position on the hydraulic support. Use the positioning holes to clarify the installation position of the mine pressure gauge. Move the arc-shaped support plate to abut the bottom of the mine pressure gauge to ensure the stability of the mine pressure gauge position. Close the L-shaped top cover to enclose the mine pressure gauge inside the device casing. Observe the mine pressure gauge reading directly through the observation window, thus protecting the mine pressure gauge. Fix it at a suitable height for convenient maintenance. This solves the problem that most mine pressure gauges are hung at a high position, making observation and maintenance inconvenient. They are also mostly directly exposed to the construction environment, which can easily affect their accuracy and lifespan. This enhances the practical value of the device.

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] Example 1 Please see Figure 1 , Figure 2 and Figure 3This utility model provides an embodiment of a hydraulic support mine pressure gauge fixing device, including a device housing 1 and a positioning hole 2 opened at the front end of the device housing 1, the positioning hole 2 corresponding to the installation position of the mine pressure gauge in the hydraulic support. It also includes an installation component, an L-shaped top cover 3, an observation window 4, a locking component, an arc-shaped support plate 5, and a moving component. The device housing 1 is fixed to the outside of the hydraulic support by the installation component. The rear end of the device housing 1 is hinged to the L-shaped top cover 3. The L-shaped top cover 3 closes the device housing 1 by the locking component. An observation window 4 is provided on one side of the top plate of the L-shaped top cover 3, the observation window 4 corresponding to the position of the mine pressure gauge dial inside the device housing 1. An arc-shaped support plate 5 is provided on the bottom inner side of the device housing 1. The arc-shaped support plate 5 is displaced by the moving component. The top of the middle part of the arc-shaped support plate 5 is provided as an elastic pad with a certain elasticity.

[0018] Please see Figure 2 and Figure 3 In this embodiment, the mounting component includes a hanging ear 101, a first mounting hole 102, and a second mounting hole 103. The front ends of the device housing 1 are symmetrically provided with hanging ears 101. The hanging ears 101 are arc-shaped, and the arc surface of the hanging ears 101 fits against the outer wall of the hydraulic support. A first mounting hole 102 is provided on one side of the hanging ear 101. The bolt is screwed into the first mounting hole 102 to fix the installation position of the device housing 1. Two sets of second mounting holes 103 are symmetrically provided on the inner front end of the device housing 1. The bolt is screwed into the second mounting hole 103 to further fix the installation position of the device housing 1. The device housing 1 is held in place at the designated position of the hydraulic support by the hanging ear 101. Fasteners are screwed into the second mounting holes 103 to initially fix the position of the device housing 1. Then, the fasteners are screwed into the first mounting hole 102 so that the hanging ear 101 assists in supporting and fixing the device housing 1, ensuring that the device housing 1 is stably installed at the designated position of the hydraulic support. The locking assembly includes a third mounting hole 301 and a mounting groove 302. The top plate of the L-shaped top cover 3 is symmetrically provided with the third mounting hole 301 on both sides. The top of the device housing 1 is symmetrically provided with two sets of mounting grooves 302. The mounting grooves 302 correspond to the positions of the third mounting holes 301. The fastener is screwed into the third mounting hole 301 to tighten the L-shaped top cover 3. The L-shaped top cover 3 is closed so that the third mounting hole 301 and the mounting groove 302 are in a continuous correspondence. The fastener is screwed into the third mounting hole 301 so that one end of the fastener is screwed into the mounting groove 302, thereby flexibly opening and closing the L-shaped top cover 3.

[0019] Please see Figure 4In this embodiment, the moving component includes a T-shaped groove 501 and a T-shaped slider 502. Two sets of T-shaped grooves 501 are symmetrically opened on the bottom inner side of the device housing 1. T-shaped sliders 502 are symmetrically arranged on both sides of the bottom end of the arc-shaped support plate 5. The T-shaped sliders 502 slide along the T-shaped grooves 501. After the mine pressure gauge is installed in the device housing 1, the arc-shaped support plate 5 is pushed to move, so that the T-shaped sliders 502 slide synchronously along the T-shaped grooves 501, thereby moving the arc-shaped support plate 5 to a suitable support position to ensure that the mine pressure gauge is placed stably.

[0020] When fixing the mine pressure gauge, the hanging lug 101 is clipped onto the outer wall of the hydraulic support, so that the positioning hole 2 is aligned with the corresponding hole groove of the hydraulic support. The fasteners are screwed into the first mounting hole 102 and the second mounting hole 103 in sequence, so that the outer shell 1 of the device is stably fixed in the designated position of the hydraulic support. Then, the mine pressure gauge connecting column is screwed into the positioning hole 2 to complete the installation of the mine pressure gauge. Subsequently, the arc-shaped support plate 5 is moved to drive the T-shaped slider 502 to slide along the T-shaped slide groove 501, so that the arc-shaped support plate 5 abuts against the bottom of the mine pressure gauge for support. Finally, close the L-shaped top cover 3 to seal the mine pressure gauge inside the device housing 1, so that the third mounting hole 301 and the mounting groove 302 are aligned and connected. Screw the fastener into the third mounting hole 301, so that one end of the fastener is screwed into the mounting groove 302, lock and close the L-shaped top cover 3, and observe the mine pressure gauge reading directly through the observation window 4.

[0021] Example 2 Please see Figure 5 The difference from Embodiment 1 is that, in this embodiment, an observation component is provided on the inner side of the top plate of the L-shaped top cover 3. The observation component includes a power supply 601 and a ring light strip 602. The power supply 601 is provided at the bottom of the L-shaped top cover 3, and the ring light strip 602 is provided on the outer edge of the observation window 4. The power supply 601 is equipped with a detachable battery, which powers the ring light strip 602. The ring light strip 602 illuminates the surface of the mine pressure gauge inside the device housing 1, ensuring that readings can be made intuitively even in the dim working environment inside the mine.

[0022] Through the above steps, the device housing 1 is stably fixed to the designated position of the hydraulic support by setting the installation components. The installation position of the mine pressure gauge is determined by the positioning hole 2. The position of the arc-shaped support plate 5 is flexibly moved by the moving components so that the arc-shaped support plate 5 abuts against the bottom of the mine pressure gauge, ensuring the stability of the mine pressure gauge position. The L-shaped top cover 3 is closed to enclose the mine pressure gauge inside the device housing 1. The L-shaped top cover 3 is locked to the device housing 1 by the locking components. The mine pressure gauge reading is directly observed through the observation window 4, thus protecting the mine pressure gauge and fixing it at a suitable height, extending the service life of the mine pressure gauge, facilitating direct observation of the dial reading, and making maintenance work convenient.
