[0023] Combine the following Figure 1 The specific structure and working principle of the pump-filled concrete column anti-collapse and deviation-correcting device of the present invention are described.

[0024] Figure 1 The schematic diagram of the structure of the pump-filled concrete column anti-collapse and deviation correction device provided by the present invention is illustrated as follows: Figure 1 As shown, the pump-filled concrete column anti-collapse and correction device includes a correction handrail 100, a fixed support 200 and a linear drive assembly. The correction handrail 100 is used to be connected to the concrete column; the fixed support 200 is used to be connected to the laneside support device; the linear drive assembly is connected to the correction handrail 100 and the fixed support 200, and the linear drive assembly is used to drive the correction handrail 100 to move closer to or away from the fixed support 200 to correct the deviation of the concrete column.

[0025] The pump-filled concrete column anti-falling and deviation-correcting device provided by the present invention prevents the concrete column from deflecting before the concrete column is pumped; when the concrete column deflects, the correction handrail 100 is driven by the linear drive component to move closer to or away from the fixed support 200 to correct the deviation of the concrete column. The concrete column is always kept vertical to the tunnel roof, which improves the overall stability of the concrete column and enhances the safety of production.

[0026] In one embodiment of the present invention, Figure 1As shown, the linear drive assembly includes a pusher 300 and a puller 400. The pusher 300 is connected to the correction handrail 100, and the pusher 300 is used to push the correction handrail 100 away from the fixed support 200. The pusher 300 can be a hydraulic cylinder, or an electric push rod or other linear drive member. The puller 400 is connected to the fixed support 200 and the pusher 300, and the puller 400 is used to pull the correction handrail 100 closer to the fixed support 200. The pusher 300 pushes the concrete column to move to the right, thereby correcting the concrete column from deviating to the left. The puller 400 is used to pull the concrete column to the left, thereby correcting the concrete column from deviating to the right.

[0027] In one embodiment of the present invention, Figure 1 As shown, the push member 300 includes a hydraulic push rod 310 and a control pump 320. The telescopic rod of the hydraulic push rod 310 is connected to the correction handrail 100. Preferably, the telescopic rod of the hydraulic push rod 310 rotates with the correction handrail 100 so that there is a certain movable space between the telescopic rod and the correction handrail 100. The cylinder of the hydraulic push rod 310 is connected to the pulling member 400. Preferably, the cylinder of the hydraulic push rod 310 is coaxially arranged with the pulling member 400, that is, the central axis of the cylinder of the hydraulic push rod 310 and the central axis of the pulling member 400 are in the same straight line.

[0028] The control pump 320 is connected to the cylinder of the hydraulic push rod 310. For the convenience of operation, the control pump 320 is connected to the cylinder of the hydraulic push rod 310 through a hydraulic oil pipe, and the operator can operate the control pump 320 from a distance. The control pump 320 is used to control the telescopic rod of the hydraulic push rod 310 to extend and retract. When the control pump 320 pumps hydraulic oil into the cylinder, the telescopic rod of the hydraulic push rod 310 extends; when the hydraulic oil in the cylinder flows back to the control pump 320, the telescopic rod of the hydraulic push rod 310 shortens. The control pump 320 can be electrically controlled or manually controlled, which is determined according to actual needs.

[0029] It should be noted here that the control pump 320 can be an emulsion driven pump for the coal mining working face (directly connected to the emulsion pipe of the working face to provide power and switch control), of course, it can also be a manual pressure pump.

[0030] In one embodiment of the present invention, the pulling member 400 includes a screw rod, one end of which is threadedly engaged with the cylinder body of the hydraulic push rod 310. Specifically, a threaded hole is provided at one end of the cylinder body close to the screw rod, and one end of the screw rod is threadedly engaged with the threaded hole. Of course, a threaded sleeve can also be provided on the cylinder body, and the cylinder body is threadedly engaged with the screw rod through the threaded sleeve. The other end of the screw rod is rotationally engaged with the fixed support member 200, so that when the screw rod rotates, the fixed support member 200 will not be driven to rotate.

[0031] In one embodiment of the present invention, the pulling member 400 also includes a rotating handle, which is connected to the screw rod. The rotating handle is a rod-shaped structure, the rotating handle is perpendicular to the screw rod, and the rotating handle is welded to the screw rod. Of course, a through hole can also be set on the screw rod, and the rotating handle can be inserted into the through hole. The rotating handle is used to drive the screw rod to rotate. When the rotating handle is rotated by hand, the rotating handle drives the screw rod to rotate in the forward direction. Since the screw rod cooperates with the cylinder thread, the screw rod can pull the concrete column to the fixed support member 200 under the action of the thread, that is, pull the concrete column to the left to correct the concrete column from deviating to the right. Of course, when the screw rod is rotated in the opposite direction, the concrete column can also be pushed to the right to move to correct the concrete column from deviating to the left. However, since the adjustment range of the screw rod is small, the screw rod can be used as an auxiliary hydraulic push rod 310 for fine adjustment.

[0032] In one embodiment of the present invention, the correction handrail 100 includes two first arc-shaped steel hoops 110. Of course, the number of the first arc-shaped steel hoops 110 is not limited thereto, and may be three, four or more, depending on actual needs. The two ends of the two first arc-shaped steel hoops 110 are detachably connected in a one-to-one manner to facilitate the correction handrail 100 to be sleeved on the outer periphery of the concrete column, and one of the first arc-shaped steel hoops 110 is connected to the linear drive assembly. Specifically, Figure 1 As shown, the first arc-shaped steel hoop 110 is semicircular, and both ends of the first arc-shaped steel hoop 110 are provided with connecting parts, and the connecting parts are provided with through holes, and the connecting parts of the two first arc-shaped steel hoops 110 are connected by bolts. Of course, the specific structural form of the correction handrail 100 is not limited to the arc-shaped steel hoop, and can also be an iron chain or other structural forms.

[0033] In one embodiment of the present invention, the fixed support member 200 includes two second arc-shaped steel hoops 210. Of course, the number of the second arc-shaped steel hoops 210 is not limited thereto, and may be three, four or more, depending on actual needs. The two ends of the two second arc-shaped steel hoops 210 are detachably connected in a one-to-one manner to facilitate the fixed support member 200 to be mounted on the laneside support device, and one of the second arc-shaped steel hoops 210 is connected to the linear drive assembly. Specifically, as Figure 1 As shown, the second arc-shaped steel hoop 210 is semicircular, and both ends of the second arc-shaped steel hoop 210 are provided with connecting parts, and the connecting parts are provided with through holes, and the connecting parts of the two second arc-shaped steel hoops 210 are connected by bolts. Of course, the specific structural form of the fixed support member 200 is not limited to the arc-shaped steel hoop, and can also be an iron chain or other structural forms.

[0034] In one embodiment of the present invention, the control pump 320 in this embodiment is an electric hydraulic pump, and the pump-filled concrete column anti-falling and correction device also includes an inclination sensor, which is arranged on the correction handrail 100 and is electrically connected to the linear drive assembly, that is, the inclination sensor is electrically connected to the electric hydraulic pump. The inclination sensor can be arranged on any one of the two first arc-shaped steel hoops 110, and the inclination sensor is used to detect the inclination angle of the correction handrail 100 to control the linear drive assembly to drive the correction handrail 100 close to or away from the fixed support 200. When the concrete column deviates, the angle of the correction handrail 100 will change. When the inclination sensor detects that the angle of the correction handrail 100 tilting to the left exceeds a predetermined range, the inclination sensor sends an electrical signal to the electric hydraulic pump. After receiving the electrical signal, the electric hydraulic pump pumps hydraulic oil into the cylinder body, and the telescopic rod of the hydraulic push rod 310 extends, and the hydraulic push rod 310 pushes the concrete column to move to the right, thereby correcting the left deviation of the concrete column. When the inclination sensor detects that the angle of the correction handrail 100 tilting to the right exceeds a predetermined range, although the hydraulic push rod 310 cannot be controlled to correct the concrete column, an alarm can be issued through the alarm component to prompt the operator.

[0035] In one embodiment of the present invention, the pump-filled concrete column anti-falling and deviation correction device further includes a pressure sensor, which is connected to the cylinder of the hydraulic push rod 310. The pressure sensor is used to detect the internal pressure of the cylinder to control the linear drive assembly to drive the correction handrail 100 to move closer to or away from the fixed support 200. When the concrete column does not deviate, the pressure in the cylinder is stable, and the pressure detected by the pressure sensor is within a certain range. When the concrete column deviates to the left, the pressure in the cylinder increases. When the pressure detected by the pressure sensor exceeds the preset pressure range, the pressure sensor sends an electrical signal to the electric hydraulic pump. After receiving the electrical signal, the electric hydraulic pump pumps hydraulic oil into the cylinder, and the telescopic rod of the hydraulic push rod 310 extends. The hydraulic push rod 310 pushes the concrete column to move to the right, thereby correcting the deviation of the concrete column to the left. When the concrete column deviates to the right, the pressure in the cylinder decreases. Since the hydraulic push rod 310 does not have the ability to pull the concrete column to move to the left, it is necessary to manually rotate the screw to pull the concrete column to the left to correct the deviation of the concrete column to the right.

[0036] In one embodiment of the present invention, the pump-filled concrete column anti-collapse and correction device also includes an alarm component, which is electrically connected to the pressure sensor. When the pressure inside the cylinder exceeds a preset range, the alarm component outputs an alarm message. The alarm component is an indicator light, and correspondingly, the alarm message is a light; the alarm component can also be a buzzer, and correspondingly, the alarm message is a sound. Of course, the specific type of the alarm component is not limited to this, and it can also be a vibrator or other alarm. When the pressure detected by the pressure sensor exceeds the preset pressure range, the pressure sensor sends an electrical signal to the alarm component, and the alarm component reminds the staff that the concrete column has deviated.

[0037] It should be noted here that the pressure detected by the pressure sensor here exceeds the preset pressure range, which may be that the pressure detected by the pressure sensor is greater than the preset pressure range, or that the pressure detected by the pressure sensor is less than the preset pressure range.

[0038] How to use the pump-filled concrete column anti-collapse correction device: During installation, first rotate the screw rod so that most of the screw rod is outside the cylinder body, providing conditions for pulling the concrete column to move to the left by rotating the screw rod, then open the two first arc-shaped steel hoops 110 to put the concrete column between the two first arc-shaped steel hoops 110, and then open the two second arc-shaped steel hoops 210 to put the lane side support device between the two second arc-shaped steel hoops 210, and adjust the length of the telescopic rod through the hole to keep the concrete column vertical to the roadway roof. When the concrete column deviates to the left, control the telescopic rod of the hydraulic push rod 310 to extend, and the hydraulic push rod 310 pushes the concrete column to move to the right, thereby correcting the leftward deviation of the concrete column; when the concrete column deviates to the right, rotate the rotating handle by hand, and the rotating handle drives the screw rod to rotate in the forward direction. Under the cooperation of the screw rod and the cylinder body, the concrete column can be pulled to the left to correct the rightward deviation of the concrete column.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
