[0028] The present application has the following advantages:

[0029] 1. This high-altitude sliding installation equipment for the steel truss roof rotates the third hydraulic cylinder, causing it to drive the square plate to rotate 90 degrees. Liquid is then injected into the third hydraulic cylinder, which propels the expansion and contraction of the third hydraulic cylinder. This pushes the square plate against the second steel frame inside the steel truss roof.

In this way, the square plate can vertically contact the second steel column. When the second plate is tilted 20 degrees, its arc-shaped bar will rotate 20 degrees counterclockwise on the current basis, and then the arc-shaped bar will contact the telescopic column at the 110-degree position. In this way, the rotation angle of the third hydraulic cylinder and the square plate is automatically adjusted according to the inclination of the second plate, so that the square plate can always be perpendicular to the second steel column, thereby improving stability.

[0031] 3. The high-altitude sliding installation equipment of the steel truss roof is equipped with two fourth hydraulic cylinders at the other end of the square plate. The two fourth hydraulic cylinders are extended and retracted 45 degrees to contact the first steel column of the steel truss roof, thereby forming a right-angled triangle structure with the steel frame of the steel truss roof. The right-angled triangle structure has strong stability. Therefore, when the first hydraulic cylinder pushes the steel frame of the steel truss roof structure to move, the stability and strength between the first steel column and the second steel column are increased through the right-angled triangle structure, thereby further reducing the deformation of the steel column.

Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0041] Embodiment 1

[0042] Please refer to Figures 1-2 One kind steel truss roof high-altitude slip installation equipment, it includes:

[0043] Guide rail 1;

[0044] Slide rail 2, slide rail 2 is arranged on the upper end surface of guide rail 1;

[0045] Sliding block 4, sliding block 4 is slidably connected inside slide rail 2, and the upper end of sliding block 4 is provided with connecting plate 5;

[0046] First hydraulic cylinder 7, one end of first hydraulic cylinder 7 is hingedly connected to one end of connecting plate 5, and the other end of first hydraulic cylinder 7 is hingedly connected with first plate 12;

[0047] Clamping device 9, one end of clamping device 9 is movably connected to one end of first plate 12;

[0048] The clamping device 9 comprises a second plate 91 movably connected to one end of the first plate 12, a clamping groove 10 is arranged between the second plate 91 and the first plate 12, a steel truss is used to be inserted into the clamping groove 10, one end of the second plate 91 is movably connected with a third hydraulic cylinder 92, and a square plate 93 is installed at one end of the third hydraulic cylinder 92, and the square plate 93 is used to abut against the internal steel frame of the steel truss roof;

[0049] The calibration device 8 is installed at the lower end of the clamping device 9, and is used to judge whether the lower end of the second plate 91 is perpendicular to the upper end surface of the guide rail 1, and adjust the axis of the third hydraulic cylinder 92 to be parallel to the upper end surface of the guide rail 1 according to the judgment result.

[0050] The steel truss roof structure is composed of a plurality of steel structures, and is generally shaped as a semicircle;

[0051] According to Figure 1 and Figure 2 , the steel truss roof structure is placed on the upper end surface of the guide rail 1, and one of the steel structures at one end of the steel truss roof structure is clamped by the first plate 12 and the second plate 91, hydraulic rods are installed on both sides of the sliding block 4, hydraulic oil is transmitted to the sliding block 4, the hydraulic rods of the sliding block 4 are pushed to abut against the inner wall of the guide rail 1 by the hydraulic oil, so as to fix the sliding block 4, at this time, hydraulic oil is transmitted to one end of the first hydraulic cylinder 7, so as to push the hydraulic cylinder of the first hydraulic cylinder 7 to slide, the working principle of the first hydraulic cylinder 7 is not described in detail, the first plate 12 and the second plate 91 are driven to slide to one end by the hydraulic cylinder of the first hydraulic cylinder 7, so as to realize the high-altitude sliding of the steel truss roof structure, then the hydraulic rods at the sliding block 4 are depressurized, so that the hydraulic rods of the sliding block 4 do not abut against the guide rail 1, at this time, hydraulic oil is transmitted to the other end of the first hydraulic cylinder 7, because the steel truss roof structure has a heavy weight, and the hydraulic rods of the sliding block 4 do not abut against the guide rail 1 at this time, the hydraulic rods are pushed to slide to one end, the sliding hydraulic rods pull the sliding block 4 and the connecting plate 5 to slide, so as to realize the position of the sliding block 4, then the above scheme is repeatedly implemented, and the first hydraulic cylinder 7 pushes the steel truss roof structure to move;

[0052] Further, because the steel truss roof structure is assembled by a plurality of steel frames, and the first plate 12 and the second plate 91 can only clamp one steel frame, the steel frame is pushed to drive the whole steel truss roof structure to move, so that the steel frame may be deformed by being extruded, therefore, in order to increase the contact area and improve the strength, the third hydraulic cylinder 92 and the square plate 93 are installed at one end of the second plate 91, and the specific implementation is according to Figure 2As shown, when the first plate 12 and the second plate 91 clamp the steel frame, the square plate 93 connected with the third hydraulic cylinder 92 is parallel to the second plate 91, then by rotating the third hydraulic cylinder 92, the third hydraulic cylinder 92 drives the square plate 93 to rotate ninety degrees, then liquid is injected into the interior of the third hydraulic cylinder 92, the third hydraulic cylinder 92 is pushed to extend or retract by the liquid, so as to push the square plate 93 to abut against the second steel frame in the steel truss roof, thus increasing the contact area and improving the strength by clamping the first steel frame and abutting against the second steel frame, and the extrusion force of the first hydraulic cylinder 7 pushing to one end is shared by the two steel frames, so as to reduce the risk of deformation of the steel frame;

[0053] Further, when the first steel frame of the steel truss roof structure is arc-shaped, after clamping by the first plate 12 and the second plate 91, the first plate 12 and the second plate 91 are necessarily not perpendicular to the upper end surface of the guide rail 1, so that the third hydraulic cylinder 92 extending outwards cannot be vertically pushed to abut against the square plate 93 on the second steel frame, thereby causing the second steel frame to not be fully stressed, and unable to share the pushing force of the first hydraulic cylinder 7 with the first steel frame, so that the calibration device 8 is rotatably connected to one end of the second plate 91, the calibration device 8 selects an inclination sensor, detects whether the second plate 91 is inclined, and obtains monitoring data, for example, taking the upper end surface of the guide rail 1 as a horizontal line, the second plate 91 is inclined by twenty degrees, at this time, the angle between one end of the second plate 91 and the upper end of the guide rail 1 is seventy degrees, so that when the second plate 91 is perpendicular to the guide rail 1, rotating the third hydraulic cylinder 92 by ninety degrees can make the axis of the third hydraulic cylinder 92 perpendicular to the second steel frame, but at this time, the second plate 91 is inclined by twenty degrees, so that the third hydraulic cylinder 92 needs to be rotated by one hundred and ten degrees on the basis of ninety degrees, so that the third hydraulic cylinder 92 is perpendicular to the second steel frame;

[0054] It should be particularly pointed out that the second plate 91 in the initial state is perpendicular to the upper end surface of the guide rail 1.

[0055] Embodiment 2

[0056] This embodiment is an improvement based on embodiment 1, for details, please refer to Figures 1-2 The calibration device 8 includes a second rotating shaft 81 rotatably installed at one end of the second plate 91, the lower end of the second rotating shaft 81 is installed with an extension rod 82, the lower end of the extension rod 82 is installed with a liquid storage tank 83, the liquid storage tank 83 swings to drive the second rotating shaft 81 to rotate under the action of gravity;

[0057] The interior of the second plate 91 is further installed with an arc-shaped sleeve 85, the interior of the arc-shaped sleeve 85 is slidably connected with an arc-shaped plate 88, one end of the arc-shaped plate 88 penetrates through one end of the arc-shaped sleeve 85, one end of the arc-shaped sleeve 85 is installed with an arc-shaped strip 13, one end of the second plate 91 is further rotatably connected with a first rotating shaft 15, one end of the third hydraulic cylinder 92 is connected with one end of the first rotating shaft 15.

[0058] The outer surface of the arc sleeve 85 is further provided with a plurality of telescopic columns 86 , and the telescopic columns 86 are connected to the arc sleeve 85 via a fourth spring 87 ;

[0059] An arc-shaped bar 84 is installed on the outer surface of the second rotating shaft 81 . The arc-shaped bar 84 is used to squeeze the telescopic column 86 to slide, and limit the sliding distance of the arc-shaped plate 88 by sliding the telescopic column 86 .

[0060] The calibration device 8 includes a second rotating shaft 81, a telescopic rod 82, a liquid storage tank 83, an arc-shaped bar 84, an arc-shaped sleeve 85, a telescopic column 86, a fourth spring 87, an arc-shaped plate 88 and a fifth spring 89;

[0061] By injecting liquid into the liquid storage tank 83, the weight of the liquid storage tank 83 is increased. Then, when the second plate 91 is tilted, the second rotating shaft 81 is kept perpendicular to the upper end surface of the guide rail 1 under the action of the liquid storage tank 83. Figure 3 As shown, the arc strip 84 in the initial state is perpendicular to the upper end surface of the guide rail 1. When the second plate 91 tilts, the liquid storage tank 83 drives the second rotating shaft 81 and the arc strip 84 to rotate. Since a plurality of telescopic columns 86 are installed on the outer surface of the arc sleeve 85, and the plurality of telescopic columns 86 are arranged in a circular array around the axis of the second rotating shaft 81, and each telescopic column 86 represents a scale, when the arc strip 84 is finally squeezed onto a certain telescopic column 86, it indicates the degree of tilt of the second plate 91 at this time. Figure 3 As shown, under normal circumstances, the arc-shaped bar 84 is perpendicularly in contact with the telescopic column 86 in the middle, so that when the arc plate 88 slides, the end of the arc-shaped plate 88 will contact the telescopic column 86 in the middle, so that the arc-shaped plate 88 drives the first rotating shaft 15 to rotate 90 degrees, and the first rotating shaft 15 drives the third hydraulic cylinder 92 and the square plate 93 to rotate 90 degrees, so that the square plate 93 can vertically contact the second steel column. When the second plate 91 is tilted 20 degrees, the arc-shaped bar 84 will rotate 20 degrees counterclockwise on the current basis, and then the arc-shaped bar 84 will contact the telescopic column 86 at the 110-degree position. In this way, the rotation angle of the third hydraulic cylinder 92 and the square plate 93 is automatically adjusted according to the inclination of the second plate 91, so that the square plate 93 can always be perpendicular to the second steel column.

[0062] Compared with the calibration device 8 using an inclination sensor, this embodiment does not require calibration. Moreover, when multiple clamping devices 9 push the steel truss roof at the same time, the data detected by multiple inclination sensors is too large, requiring a stronger processor for calculation. Compared with the inclination sensor, this embodiment does not require too much maintenance and can operate in harsh environments.

[0063] Example 3

[0064] This embodiment is an improvement made on the basis of embodiment 2. For details, please refer toFigures 1-2 The upper and lower ends of the square plate 93 are rotatably connected with the fourth hydraulic cylinder 94, the axis of the fourth hydraulic cylinder 94 is at an angle of 45 degrees with the extension line of the upper end surface of the square plate 93, and the angle between the two unfolded fourth hydraulic cylinders 94 is 90 degrees;

[0065] One end of the fourth hydraulic cylinder 94 is used to abut against the steel frame of the steel truss roof;

[0066] According to Figure 1 and Figure 2 As shown in order to further improve the stability of the steel truss roof structure steel frame and reduce deformation, two fourth hydraulic cylinders 94 are arranged at the other end of the square plate 93, and the two fourth hydraulic cylinders 94 are unfolded at an angle of 45 degrees to abut against the first steel column of the steel truss roof, so as to form a right triangle structure with the steel frame of the steel truss roof. The stability of the right triangle structure is strong, so as to increase the stability and strength between the first steel column and the second steel column through the right triangle structure when the first hydraulic cylinder 7 pushes the steel truss roof structure steel frame to move, thereby further reducing the occurrence of steel column deformation;

[0067] It should be particularly pointed out that the operation principles of the third hydraulic cylinder 92, the fourth hydraulic cylinder 94 and the second hydraulic cylinder 11 are the same as that of the first hydraulic cylinder 7, and all adopt hydraulic extrusion of the internal rod sliding.

[0068] Embodiment 4

[0069] This embodiment is an improvement based on embodiment 3. For details, please refer to Figures 1-5 One end of the square plate 93 is provided with a plurality of force plates 31, the force plates 31 and the square plate 93 are connected through the third springs 32, the other end of the force plates 31 is provided with the racks 33, and the racks 33 penetrate the square plate 93;

[0070] The other end of the square plate 93 is rotatably connected with the rotating shaft 35, the upper end of the rotating shaft 35 is provided with the gear 34, the racks 33 are engaged with the gear 34, one end of the rotating shaft 35 is provided with the second hydraulic cylinder 11, and the axis of the second hydraulic cylinder 11 is at an angle of 45 degrees with one end of the square plate 93.

[0071] According to Figure 5 As shown in order to further increase the strength of the first steel column, a plurality of force plates 31 are arranged at one end of the square plate 93, whether there is other steel frame near the second steel frame is detected through the force plates 31, when the force plates 31 are extruded, it indicates that there is other steel frame near the second steel frame, so as to abut against the other steel frame near the second steel frame through the force plates 31, so as to increase the support strength;

[0072] Furthermore, a rack 33 is provided at one end of the force-bearing plate 31. When the force-bearing plate 31 is squeezed, the force-bearing plate 31 will drive the rack 33 to slide, and the rack 33 will engage the gear 34, so that the gear 34 will rotate, and the gear 34 will drive the rotating shaft 35 to rotate, and the rotating shaft 35 will drive the second hydraulic cylinder 11 to rotate. The length of the rack 33 can only drive the gear 34 to rotate forty-five degrees, so the rotating shaft 35 will drive the second hydraulic cylinder 11 to rotate forty-five degrees, so that one end of the second hydraulic cylinder 11 can contact the first steel frame, so that the first steel frame forms a right triangle with other steel frames near the second steel frame through the two second hydraulic cylinders 11, thereby further increasing the supporting strength.

[0073] One end of the second hydraulic cylinder 11 and one end of the fourth hydraulic cylinder 94 are both mounted with a universal plate 6, which includes a ball 61, a spring 62, a connecting rod 63 and a rubber plate 64;

[0074] A connecting rod 63 is installed at one end of the ball 61, and a rubber plate 64 is installed at one end of the connecting rod 63. The rubber plate 64 is used to abut against the steel frame of the steel truss roof. A spring 62 is also installed at one end of the rubber plate 64 for pushing the ball 61 to reset.

[0075] according to Figure 5 As shown, the third hydraulic cylinder 92, the fourth hydraulic cylinder 94 and the second hydraulic cylinder 11 all include a cylinder body and a shaft body. The shaft body is slidably connected to the inside of the cylinder body, and the ball 61 is rotatably connected to one end of the shaft body. When the steel column is bent, the bent steel column abuts against the rubber plate 64. After the rubber plate 64 is squeezed by the bent steel column, it drives the connecting rod 63 and the ball 61 to adjust the angle. In this way, the rubber plate 64 can abut against the steel column over a large area, thereby forming a stable support, thereby improving the stability of the first hydraulic cylinder 7 in pushing the steel truss roof to move.

[0082] Drive: According to Figure 6 As shown, the first steel column is placed in the clamping groove 10, and then the threaded rod 17 is rotated so that the threaded rod 17 is clamped in the clamping groove 18, and then the nut 19 is rotated to clamp the first plate 12 and the second plate 91, thereby fixing the first steel column;

[0083] By transferring liquid to the liquid storage tank 83, the weight of the liquid storage tank 83 is increased, so that the liquid storage tank 83 can remain perpendicular to the upper end surface of the guide rail 1 under the action of gravity. In this way, the inclination angle of the second plate 91 can be obtained, and the rotation angle of the third hydraulic cylinder 92 can be adjusted according to the inclination angle. Figure 7 As shown, when the hydraulic pressure at the liquid storage tank 83 gradually increases, the piston plate 24 is squeezed to slide downward, so that the liquid storage tank 83 is connected to the counterbore groove 23, and then the liquid at the liquid storage tank 83 flows into the counterbore groove 23, and is transmitted to the inside of the piston cavity 27 through the third transmission hole 26 at the counterbore groove 23, thereby pushing the clamping column 22 to be clamped into the inside of the limit groove 3, so as to prevent the liquid storage tank 83 from swinging due to the inertia of the second plate 91 after it moves;

[0084] Furthermore, since there may be dirt inside the slide rail 2, a spray hole 30 is provided at the lower end of the piston rod 21. Figure 7As shown, when the piston cavity 27 pushes the clamping column 22 to slide to the limit, the fourth transmission hole 29 is in communication with the piston cavity 27, so that the fourth transmission hole 29 transmits the liquid in the piston cavity 27 to the spray hole 30, and sprays the slide rail 2 through the spray hole 30, so as to reduce the situation that the guide rail 1 is stuck by impurities during the sliding of the slide rail 2;

[0085] According to Figure 3 As shown, by transmitting hydraulic oil to the inside of the arc-shaped sleeve 85, the arc-shaped plate 88 is pushed to slide, the arc-shaped strip 13 is driven to slide through the sliding of the arc-shaped plate 88, the first rotating shaft 15 is driven to rotate by the arc-shaped strip 13, the third hydraulic cylinder 92 and the square plate 93 are driven to rotate and adjust the angle by the first rotating shaft 15, when the hydraulic pressure in the inside of the arc-shaped sleeve 85 is greater than the first pressure relief valve, the liquid in the inside of the arc-shaped sleeve 85 will flow into the first transmission hole 14 through the first pressure relief valve, the hydraulic oil is transmitted to the inside of the third hydraulic cylinder 92 through the first transmission hole 14, so as to push the third hydraulic cylinder 92 to extend and retract, and then when the hydraulic pressure in the inside of the third hydraulic cylinder 92 is greater than the second pressure relief valve, the hydraulic pressure in the inside of the third hydraulic cylinder 92 will pass through the second pressure relief valve to enter the second transmission hole 16, the hydraulic oil is transmitted to the inside of the second hydraulic cylinder 11 through the second transmission hole 16, so as to push the second hydraulic cylinder 11 to extend and retract.
