Description

Technical Field

[0001] The present invention relates to the technical field of mining equipment, and in particular to an installation device for a supporting scaffold. Background Art

[0002] Ore, especially coal mining, requires a large number of tunnels to be excavated underground during the mining process, and tunnel supports are set up in the tunnels to keep the tunnels unobstructed and the surrounding rock stable. The support scaffolding is the main structure of the tunnel support, which includes a top beam for abutting the top of the tunnel, two retractable support columns for supporting the top beam, and a connecting shoe for abutting the side of the tunnel. The connecting shoe is rotatably arranged on the support column. In the related art, the installation equipment maintains the support column in a vertical state, then drives the support column to move in the horizontal direction, and makes the connecting shoe abut the side of the tunnel, and then connects the support column to the top beam and drives the support column to extend to support the top beam. However, since the support column is already in a vertical state and the connecting shoe has abutted the side of the tunnel, during the process of extending the support column to achieve support and connecting the support column to the top beam, the position adjustment and movement of the support column in the vertical direction will drive the connecting shoe to move synchronously, affecting the stability of the abutment between the connecting shoe and the side of the tunnel, and causing friction damage between the connecting shoe and the side of the tunnel, thereby reducing the stability of the tunnel supported by the support scaffolding.

[0033] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0034] Please refer to the following Figure 1 -Attached Figure 5 The following describes an installation device for a support scaffold according to an embodiment of the invention.

[0035] like Figure 1-Figure 5 As shown, the support scaffolding includes support columns 10, connecting boots 20 and top beams 30. In the installed support scaffolding, the top beam 30 extends in the front-to-back direction and abuts the top of the tunnel, the support columns 10 extend in the up-down direction and are supported between the top beam 30 and the bottom of the tunnel, and the connecting boots 20 are rotatably provided on the support columns and abut against the side of the tunnel, thereby supporting the tunnel.

[0036] like Figure 1-Figure 5 As shown, the installation device of the supporting scaffolding according to the embodiment of the present invention includes a first frame assembly 1 , a first drive assembly 2 and a second frame assembly 3 .

[0037] The first frame component 1 can be moved along a first direction (such as Figure 1 The first drive assembly 2 is connected to the first frame assembly 1 to drive the first frame assembly 1 to move telescopically in the first direction. The second frame assembly 3 is used to grab and move the support column 10. The second frame assembly 3 is hinged to the first frame assembly 1, and the first drive assembly 2 is connected to the second frame assembly 3 to drive the second frame assembly 3 to rotate between the first position and the second position. In the first position, the center line of the second frame assembly 3 is along the second direction (as shown). Figure 1 The second direction is perpendicular to the first direction. At the second position, the extension direction of the center line of the second frame assembly 3 and the second direction have a first angle.

[0038] like Figure 1As shown, the first frame component 1 is arranged along the front-to-back direction, the first driving component 2 is connected to the first frame component 1 to drive the first frame component 1 to telescope and move along the front-to-back direction, the second frame component 3 is arranged at the front end of the first frame component 1, and moves along the front-to-back direction with the telescopic movement of the first frame component 1, the second frame component 3 is used to grasp and move the support column 10, and the length direction of the support column 10 is parallel to the extension direction of the center line of the second frame component 3, the second frame component 3 is hinged to the first frame component 1, and the first driving component 2 is connected to the second frame component 3, and the second frame component 3 can be driven to rotate between the first position and the second position through the first driving component 2. In the first position, the center line of the second frame component 3 extends along the up-down direction, and in the second position, the extension direction of the center line of the second frame component 3 has a first angle with the up-down direction.

[0039] The mounting device of the support scaffolding of the embodiment of the present invention drives the first frame assembly to drive the second frame assembly in the second position to move forward through the first driving assembly, so that the support column grasped by the second frame assembly moves forward, so as to be used to move the upper end of the support column provided with a connecting shoe to the installation position. At this time, the top beam is connected to the support column, and the connecting shoe can abut the side wall of the tunnel or have a gap with the side wall of the tunnel. Then, the second frame assembly is rotated from the second position to the first position, and the support column rotates synchronously with the second frame assembly and moves the lower end of the support column to the installation position and abuts against the bottom of the tunnel, so that the support column is installed in place and realizes the supporting function. During the rotation of the support column and the second frame assembly, the connecting shoe abuts against the side wall of the tunnel, and the connecting shoe and the support column rotate relative to each other, but the connecting boot does not displace relative to the side wall of the tunnel. Therefore, the mounting device of the support scaffolding of the embodiment of the present invention avoids the problem of displacement of the end of the support column provided with the connecting shoe during the installation process through the rotation action of the second frame assembly between the first position and the second position, which leads to reduced support stability of the support scaffolding.

[0040] In some embodiments, the first frame assembly 1 includes a first sub-frame 11 and a second sub-frame 12 connected to each other; the first drive assembly 2 includes a first telescopic cylinder 21, and the first sub-frame 11 and the second sub-frame 12 are respectively connected to the first telescopic cylinder 21 so as to move relative to each other along a first direction under the drive of the first telescopic cylinder 21; the second frame assembly 3 includes a hinge part 31, the first sub-frame 11 is hinged to the hinge part 31 through a first hinge shaft 111, and one end of the first telescopic cylinder 21 is hinged to the hinge part 31 through a second hinge shaft 211. In the projection plane orthogonal to the first direction, the projection of the first hinge shaft 111 and the projection of the second hinge shaft 211 are arranged at intervals in the second direction, so that the first telescopic cylinder 21 drives the second frame assembly 3 to rotate around the axis of the first hinge shaft 111 between the first position and the second position.

[0041] like Figure 1 and Figure 2As shown, the first frame assembly 1 includes a first sub-frame 11 and a second sub-frame 12, and the first sub-frame 11 and the second sub-frame 12 are arranged in sequence along the front-to-back direction. Preferably, the first sub-frame 11 and the second sub-frame 12 are sleeves, and the rear end of the first sub-frame 11 is sleeved on the front end of the second sub-frame 12. The first driving assembly 2 includes a first telescopic cylinder 21, which is located inside the first sub-frame 11 and the second sub-frame 12, and the front end of the first telescopic cylinder 21 is connected to the first sub-frame 11, and the rear end of the first telescopic cylinder 21 is connected to the second sub-frame 12. The first telescopic cylinder 21 drives the first sub-frame 11 and the second sub-frame 12 to slide relative to each other in the front-to-back direction, so that the first frame assembly 1 can be telescopically moved in the front-to-back direction to drive the second frame assembly 3 to move in the front-to-back direction.

[0042] The second frame assembly 3 includes a hinge part 31, the front end of the first sub-frame 11 is hinged to the hinge part 31 through the first hinge shaft 111, and the front end of the first telescopic cylinder 21 is hinged to the hinge part 31 through the second hinge shaft 211. The extension direction of the axis of the first hinge shaft 111 and the second hinge shaft 211 is orthogonal to the front-to-back direction and the up-down direction. In the projection plane orthogonal to the front-to-back direction, the projection of the first hinge shaft 111 is located below the projection of the second hinge shaft 211. When the first telescopic cylinder 21 moves in telescopic movement, it can drive the hinge part 31 to grasp around the axis of the first hinge shaft 111, thereby rotating the second frame assembly 3 between the first position and the second position.

[0043] It is understandable that the structures of the first sub-frame and the second sub-frame are not limited to being sleeves. In other embodiments, the first sub-frame and the second sub-frame may be slidably connected rods or plates, and the first telescopic cylinder is provided on one side of the first sub-frame and the second sub-frame.

[0044] It can be understood that the telescopic movement of the first frame assembly and the rotation of the second frame assembly are not limited to being carried out simultaneously. In other embodiments, the first telescopic cylinder is only used to drive the telescopic movement of the first frame assembly and is not connected to the second frame assembly. The first drive assembly includes a rotating shaft, which is connected to the second frame assembly to drive the second frame assembly to rotate.

[0045] In some embodiments, the first sub-frame 11 has an inner cavity, and at least part of the hinged portion 31 is located in the inner cavity of the first sub-frame 11. The installation device of the supporting scaffolding also includes an angle adjustment member 4, which is provided on the first sub-frame 11 and can be moved in a second direction relative to the first sub-frame 11. One end of the angle adjustment member 4 is located in the inner cavity of the first sub-frame 11. In the second position, one end of the angle adjustment member 4 abuts against the hinged portion 31.

[0046] like Figure 1 and Figure 2As shown, the rear end of the hinged portion 31 extends from the front end opening of the first sub-frame 11 into the inner cavity of the first sub-frame 11, and the size of the hinged portion 31 in the vertical direction is smaller than the size of the inner cavity of the first sub-frame 11 in the vertical direction. The first hinge shaft 111 passes through the first sub-frame 11 and the hinged portion 31 to hinge the first sub-frame 11 and the hinged portion 31 together. The second hinge shaft 211 is located in the inner cavity of the first sub-frame 11 and passes through the hinged portion 31 and the front end of the first telescopic cylinder 21 to hinge the hinged portion 31 and the front end of the first telescopic cylinder 21, thereby The rear end of the hinge part 31 is able to rotate in the inner cavity of the first sub-frame 11. The angle adjustment member 4 is preferably an adjusting bolt. The angle adjustment member 4 is arranged in the up and down directions and is threadedly connected to the first sub-frame 11 so that the angle adjustment member 4 can move up and down relative to the first sub-frame 11. The lower end of the angle adjustment member 4 is located in the inner cavity of the first sub-frame 11. In the second position, the lower end of the angle adjustment member 4 is against the upper end surface of the hinge part 31 to limit the size of the first angle. The up and down movement function of the angle adjustment member 4 can adjust the size of the first angle.

[0047] It is understandable that the hinge portion is not limited to being disposed in the inner cavity of the first subframe. In other embodiments, the hinge portion and the first subframe are arranged side by side in a direction orthogonal to the up-down direction and the front-back direction.

[0048] It is understandable that the installation device of the supporting scaffold is not limited to having an angle adjustment member. In other embodiments, the hinge portion abuts against the inner wall surface of the first sub-frame to limit the size of the first angle.

[0049] In some embodiments, the first angle ranges from -8° to +8°.

[0050] like Figure 1 and Figure 2 As shown, there are two angle adjustment members 4, and the two angle adjustment members 4 are arranged at intervals in the front-to-back direction. When the first angle is -8°, the upper end surface of the hinge part 31 abuts against one of the angle adjustment members 4. When the first angle is +8°, ​​the upper end surface of the hinge part 31 abuts against the other angle adjustment member 4.

[0051] It is understandable that the angle adjustment members are not limited to being arranged in multiple numbers at intervals in the front-to-back direction. In other embodiments, there is only one angle adjustment member, and the range of the first angle is -8° to 0° or 0° to +8°.

[0052] In some embodiments, a second angle is formed between the extension direction of the center line of the first telescopic cylinder 21 and the first direction, and the second angle ranges from 2° to 5°.

[0053] like Figure 1 and Figure 2As shown, the first telescopic cylinder 21 extends from the back to the front and is tilted upward. The extension direction of the center line of the first telescopic cylinder 21 has a second angle with the front-to-back direction. The range of the second angle is 2° to 5°, so that the first telescopic cylinder 21 can drive the hinge part 31 to rotate around the first hinge shaft 111.

[0054] It can be understood that the first telescopic cylinder is not limited to being arranged in an inclined manner. In other embodiments, the first telescopic cylinder is arranged along the second direction.

[0055] In some embodiments, the first frame assembly 1 also includes a connected third sub-frame 13 and a fourth sub-frame 14, and the second sub-frame 12 is arranged on the third sub-frame 13; the first drive assembly 2 also includes a second telescopic cylinder 22, and the third sub-frame 13 and the fourth sub-frame 14 are respectively connected to the second telescopic cylinder 22 so as to move relative to each other along the first direction under the drive of the second telescopic cylinder 22.

[0056] like Figure 1 and Figure 2 As shown, the first frame assembly 1 also includes a third sub-frame 13 and a fourth sub-frame 14, and the third sub-frame 13 and the fourth sub-frame 14 are arranged in sequence along the front-to-back direction. The third sub-frame 13 and the fourth sub-frame 14 are preferably sleeves, and the rear end of the third sub-frame 13 is sleeved on the front end of the fourth sub-frame 14. The second sub-frame 12 and the third sub-frame 13 are arranged in sequence and connected in the up-down direction. The first driving assembly 2 also includes a second telescopic cylinder 22, which is arranged inside the third sub-frame 13 and the fourth sub-frame 14, and the front end of the second telescopic cylinder 22 is connected to the third sub-frame 13, and the rear end of the second telescopic cylinder 22 is connected to the fourth sub-frame 14, so that the third sub-frame 13 and the fourth sub-frame 14 are driven by the telescopic movement of the second telescopic cylinder 22 to generate relative sliding along the front-to-back direction, further increasing the telescopic movement distance of the first frame assembly 1 in the front-to-back direction, so as to increase the movement distance of the second frame assembly 3 in the front-to-back direction.

[0057] In some embodiments, the second frame assembly 3 includes at least two gripping mechanisms 32, and the at least two gripping mechanisms 32 are spaced apart in the extension direction of the center line of the second frame assembly 3. Specifically, Figure 1 As shown, the top of the second frame assembly 3 has a gripping mechanism 32 , and the bottom of the second frame assembly 3 has a gripping mechanism 32 , and the support column 10 is gripped by the two gripping mechanisms 32 .

[0058] The grabbing mechanism 32 includes a third telescopic cylinder 321 , an abutting member 322 , a grabbing member 323 and an elastic member 324 .

[0059] The third telescopic cylinder 321 can be telescopically moved in a direction perpendicular to the center line of the second frame assembly 3. Figure 1 and Figure 3As shown, the grasping mechanism 32 also includes a main body and a rear cover 325. The main body is a sleeve with an ear plate. The third telescopic cylinder 321 is arranged along the front-to-back direction and is located in the main body. The rear cover 325 is arranged at the rear end of the main body to close and open the rear end opening of the main body, thereby facilitating the installation and removal of the third telescopic cylinder 321.

[0060] The abutment member 322 is arranged at one end of the third telescopic cylinder 321. The abutment member 322 has at least two first abutment surfaces 3221. The at least two first abutment surfaces 3221 are arranged at intervals around the center line of the abutment member 322. The first abutment surfaces 3221 extend in a direction away from the third telescopic cylinder 321 and are inclined in a direction toward the center line of the abutment member 322.

[0061] Specifically, if Figure 3 As shown, the abutment member 322 is connected to the front end of the third telescopic cylinder 321. The front end of the abutment member 322 has four first abutment surfaces 3221 spaced apart around the axis of the abutment member 322. Each first abutment surface 3221 extends away from the third telescopic cylinder 321 and is tilted toward the centerline of the abutment member 322. In other words, the front end of the abutment member 322 is pyramidal in shape. The gripping mechanism 32 also includes a guide seat 326 disposed at the front end of the body. The guide seat 326 has a guide hole extending through the guide seat 326 in the front-to-back direction. The outer peripheral surface of the rear end of the abutment member 322 abuts against the wall of the guide hole, allowing the abutment member 322 to move in the front-to-back direction under the guidance of the guide hole.

[0062] There are at least two grabbing members 323, and at least two grabbing members 323 are arranged at intervals around the center line of the abutting member 322. The grabbing member 323 has a second abutting surface 3231, and the second abutting surface 3231 abuts against the corresponding first abutting surface 3221 to drive the grabbing member 323 to move away from the center line of the abutting member 322 in a direction perpendicular to the center line of the abutting member 322.

[0063] Specifically, if Figure 3As shown, there are two grabbing members 323 spaced apart in the vertical direction. Each grabbing member 323 has a receiving slot. The receiving slot of the upper grabbing member 323 receives the upper half of the front end of the abutting member 322, while the receiving slot of the lower grabbing member 323 receives the lower half of the front end of the abutting member 322, thereby preventing the grabbing member 323 and the abutting member 322 from separating. The receiving slot has three connected slot walls, each of which is a second abutting surface 3231. The second abutting surface 3231 extends away from the third telescopic cylinder 321 and is inclined toward the centerline of the abutting member 322. The three second abutting surfaces 3231 of the receiving slot abut against the three connected first abutting surfaces 3221 of the abutting member 322 one by one. When the abutting member 322 moves forward, the first abutting surfaces 3221 push the corresponding second abutting surfaces 3231, causing the two grabbing members 323 to move away from each other in the vertical direction. Preferably, the inclination angle of the first abutting surface 3221 and the second abutting surface 3231 relative to the front-rear direction is 10° to 20°, more preferably 15°.

[0064] The elastic member 324 is connected to the grabbing member 323 to drive the grabbing member 323 to move toward the center line of the abutting member 322 in a direction perpendicular to the center line of the abutting member 322 .

[0065] Specifically, if Figure 3 As shown, the grabbing mechanism 32 also includes a front cover 327, which is arranged at the front end of the guide seat 326, and the front cover 327 has a through hole that penetrates the front cover 327 along the front-to-back direction. The front end of the grabbing member 323 extends forward from the through hole of the front cover 327, and the rear end surface of the front cover 327 is provided with a mounting groove. In the projection plane orthogonal to the front-to-back direction, the projection of the mounting groove covers the projection of the through hole of the front cover 327, and the side wall surface of the rear end of the grabbing member 323 has a protrusion, which is located in the mounting groove. There is an elastic member 324 arranged along the up and down direction between the protrusion of the grabbing member 323 and the groove wall surface of the mounting groove. The elastic member 324 is preferably a spring, and there are two springs. The two springs are arranged in a one-to-one correspondence with the two abutting members 322 to drive the corresponding abutting member 322 to move toward the other abutting member 322.

[0066] like Figure 1As shown, the support column 10 is provided with two grabbing grooves 102, which are spaced apart in the vertical direction and are arranged one-to-one with the two grabbing mechanisms 32. When the grabbing mechanism 32 grabs the support column 10, the two grabbing members 323 of the grabbing mechanism 32 extend into the grabbing groove 102. The abutting member 322 moves forward, causing the two grabbing members 323 to move away from each other, and the outer wall surfaces of the grabbing members 323 abut against the circumferential groove wall surfaces of the grabbing groove 102, thereby achieving the grabbing of the support column 10. When the abutting member 322 moves backward, the elastic member 324 drives the two grabbing members 323 to move closer to each other, causing the outer wall surfaces of the grabbing members 323 to separate from the circumferential groove wall surfaces of the grabbing groove 102, thereby releasing the support column 10.

[0067] It can be understood that the abutment is not limited to having four first abutment surfaces, and the three groove wall surfaces of the accommodating groove are not limited to being second abutment surfaces. In other embodiments, the abutment has two first abutment surfaces, and the two first abutment surfaces are arranged at intervals in the up and down directions. One of the groove wall surfaces of the accommodating groove is the second abutment surface, and the two first abutment surfaces abut against the second abutment surfaces of the two accommodating grooves one by one.

[0068] It can be understood that the number of grabbing members is not limited to two. In other embodiments, there are multiple grabbing members, each grabbing member has a second abutting surface, and the abutting member has multiple first abutting surfaces. The multiple first abutting surfaces are arranged one-to-one corresponding to the second abutting surfaces of the multiple grabbing members. On the projection surface orthogonal to the front and rear directions, the projection of the abutting member can be a circle, and the projection of each first abutting surface is an arc of a circle. The projection of the abutting member can also be a polygon, and each side of the polygon is a projection corresponding to a first abutting surface. The projection surface of the circumferential groove wall of the grabbing groove can be a circle. At this time, the outer wall surface of the abutting member is an arc surface. The projection surface of the circumferential groove wall of the grabbing groove can also be a polygon, and each side of the polygon corresponds to the outer wall surface of a grabbing member.

[0069] It can be understood that the grasping mechanism is not limited to grasping the support column when the two grasping members are relatively far away from each other and releasing the support column when the two grasping members are relatively close to each other. In other embodiments, the two grasping members abut the outer peripheral surface of the support column to clamp the support column when the two grasping members are relatively close to each other, and release the support column when the two grasping members are relatively far away from each other. At this time, the support column does not need to have a grasping groove.

[0070] It can be understood that the elastic member is not limited to being arranged in a one-to-one correspondence with the grasping member. In other embodiments, the mounting groove is circular, the elastic member is an annular rubber ring located in the mounting groove, and multiple grasping members are simultaneously abutted against the annular rubber ring. The elastic force of the annular rubber ring drives the multiple grasping members to move simultaneously toward the center line of the abutting member.

[0071] In some embodiments, the second frame assembly 3 also includes a fifth sub-frame 33, a sixth sub-frame 34, a seventh sub-frame 35 and a fourth telescopic cylinder 36. The fifth sub-frame 33, the sixth sub-frame 34 and the seventh sub-frame 35 are connected in sequence along the center line of the second frame assembly 3. The sixth sub-frame 34 is connected to the hinge part 31. The fifth sub-frame 33 and the seventh sub-frame 35 are respectively connected to the fourth telescopic cylinder 36 to drive the fifth sub-frame 33 and the seventh sub-frame 35 to move relative to each other in the extension direction of the center line of the second frame assembly 3. The fifth sub-frame 33 and the seventh sub-frame 35 are respectively provided with a grasping mechanism 32.

[0072] like Figure 1 and Figure 4 As shown, the fifth sub-frame 33, the sixth sub-frame 34, and the seventh sub-frame 35 are connected in sequence along the center line of the second frame assembly 3. Preferably, the fifth sub-frame 33, the sixth sub-frame 34, and the seventh sub-frame 35 are all sleeves. The upper end of the sixth sub-frame 34 is sleeved on the lower end of the fifth sub-frame 33, and the sixth sub-frame 34 and the fifth sub-frame 33 can slide relative to each other along the center line of the second frame assembly 3. The upper end of the seventh sub-frame 35 is sleeved on the lower end of the sixth sub-frame 34, and the seventh sub-frame 35 and the sixth sub-frame 34 can slide relative to each other along the center line of the second frame assembly 3. The sixth sub-frame 34 is connected to the hinge part 31, preferably through a locating pin. The fourth telescopic cylinder 36 is located at the fifth sub-frame The interior of the frame 33, the sixth sub-frame 34 and the seventh sub-frame 35, and the upper end of the fourth telescopic cylinder 36 is connected to the fifth sub-frame 33 and the ear plate of the grabbing mechanism 32 located above, and the lower end of the fourth telescopic cylinder 36 is connected to the seventh sub-frame 35 and the ear plate of the grabbing mechanism 32 located below, so as to drive the fifth sub-frame 33 and the seventh sub-frame 35 to move relative to each other in the extension direction of the center line of the second frame assembly 3 through the telescopic movement of the fourth telescopic cylinder 36. A grabbing mechanism 32 is provided at the upper end of the fifth sub-frame 33, and another grabbing mechanism 32 is provided at the lower end of the seventh sub-frame 35. The telescopic movement of the fourth telescopic cylinder 36 can adjust the distance between the two grabbing mechanisms 32.

[0073] Adjusting the distance between the two gripping mechanisms 32 by the fourth telescopic cylinder 36 has two effects. One effect is to enable the second frame assembly 3 to grip support columns 10 of different lengths and models. Another effect is that the support column 10 can be telescopically moved along the extension direction of its centerline. Adjusting the distance between the two gripping mechanisms 32 by the fourth telescopic cylinder 36 can change the distance between the two gripping slots 102, thereby changing the length of the support column 10. During the process of rotating the second frame assembly from the second position to the first position, the fourth telescopic cylinder 36 simultaneously drives the fifth sub-frame 33 and the seventh sub-frame 35 to move away from each other. When the second frame is in the first position, the support column 10 is also extended by the fourth telescopic cylinder 36 until the bottom of the support column 10 abuts against the bottom of the tunnel, preventing the support column 10 from being damaged by friction with the bottom of the tunnel during the rotation of the second frame assembly 3.

[0074] It is understood that the structure of the second frame assembly is not limited to Figure 4 As shown, in other embodiments, the second frame assembly does not have the fourth telescopic cylinder, and the length of the second frame assembly is fixed.

[0075] It is understandable that the second frame assembly is not limited to including the fifth sub-frame, the sixth sub-frame and the seventh sub-frame. In other embodiments, the second frame assembly only has the fifth sub-frame and the sixth sub-frame, and the fifth sub-frame and the sixth sub-frame are respectively provided with a gripping mechanism, or only has the sixth sub-frame and the seventh sub-frame, and the sixth sub-frame and the seventh sub-frame are respectively provided with a gripping mechanism.

[0076] In some embodiments, the installation device of the supporting scaffolding of the embodiment of the present invention further includes a fifth telescopic cylinder 5 , one end of the fifth telescopic cylinder 5 is connected to the seventh sub-frame 35 , and the other end of the fifth telescopic cylinder 5 is connected to the hinge part 31 .

[0077] like Figure 1 and Figure 4 As shown, the fifth telescopic cylinder 5 is arranged in the up-down direction, the upper end of the fifth telescopic cylinder 5 is connected to the hinge part 31, and the lower end of the fifth telescopic cylinder 5 is connected to the seventh sub-frame 35, so that the position of the grabbing mechanism 32 located below relative to the hinge part 31 in the up-down direction can be adjusted by the telescopic movement of the fifth telescopic cylinder 5, while the fourth telescopic cylinder 36 is maintained at a fixed length. The position of the grabbing mechanism 32 located above relative to the hinge part 31 in the up-down direction can also be adjusted, thereby adjusting the height position of the support column 10 in the tunnel.

[0078] When the first driving assembly drives the first frame assembly to drive the second frame assembly in the second position to move forward, so that the upper end of the support column grasped by the second frame assembly moves to the installation position, the height position of the support column can be adjusted by the fifth telescopic cylinder so that the top end of the support column is inserted into the installation groove of the top beam to connect the top beam with the top end of the support column. During this process, the connecting boot does not abut the side wall of the tunnel. After the top beam is connected to the support column, the size of the first angle is adjusted by rotating the second frame assembly so that the connecting boot abuts the side wall of the tunnel, and then the second frame assembly continues to rotate to the first position. During the continued rotation, the connecting boot remains in abutment with the side wall of the tunnel, and the connecting boot and the support column rotate relative to each other, but the connecting boot does not move relative to the side wall of the tunnel.

[0079] It should be noted that the installation position does not mean the position where the upper end of the support column is connected to the top beam, but a fixed position relative to the tunnel. When the upper end of the support column moves to the installation position, the top beam is in contact with the top of the tunnel. The top beam and the upper end of the support column can be connected at the installation position or in advance. For example, in other embodiments, the top beam and the upper end of the support column are connected in advance. When the position of the support column is adjusted by the first drive assembly and the fifth telescopic cylinder, the position of the top beam relative to the tunnel is also adjusted at the same time, and the top beam does not abut against the top of the tunnel. When the first drive assembly and the fifth telescopic cylinder move the upper end of the support column to the installation position, the top beam synchronously abuts against the top of the tunnel, and then the size of the first angle is adjusted by rotating the second frame assembly so that the connecting boot abuts the side of the tunnel, and then the second frame assembly continues to be rotated to the first position. During this process, the connecting boot does not move relative to the side of the tunnel.

[0080] At the same time, the fifth telescopic cylinder also plays a role in maintaining pressure. It can be understood that the installation equipment of the support scaffolding is not limited to the installation of support columns. The installation equipment of the support scaffolding can also be used to remove support columns. When the support columns are removed by the installation equipment of the support scaffolding, the fourth telescopic cylinder and the fifth telescopic cylinder shrink synchronously. The contraction of the fourth telescopic cylinder is used to contact the support column so that the support column can be removed. The contraction of the fifth telescopic cylinder is to separate the bottom of the support column from the bottom of the tunnel, avoiding the friction between the bottom of the support column and the bottom of the tunnel during the movement and / or rotation of the support column, which may cause damage to the bottom of the support column and the bottom of the tunnel, so that the support column can be reused.

[0081] It is understandable that, in other embodiments, the installation device of the supporting scaffold may not have the fifth telescopic cylinder.

[0082] In some embodiments, the support column 10 has a locking assembly 101, which is used to limit the length of the support column 10. The installation equipment of the support scaffolding also includes a trigger assembly 6, which is arranged on the second frame assembly 3. The trigger assembly 6 is used to trigger the locking assembly 101 of the support column 10. The trigger assembly 6 includes a sixth telescopic cylinder 61 and a trigger member 62. The sixth telescopic cylinder 61 can drive the trigger member 62 to move along the extension direction of the center line of the second frame assembly 3 so that the trigger member 62 abuts against the locking assembly 101.

[0083] like Figure 1 and Figure 5As shown, the support column 10 is divided into two parts arranged in sequence along the up and down directions. The support column 10 is retractable through the relative movement of the two parts of the support column 10 in the up and down directions. The lower end of the support column 10 has a locking assembly 101, and the locking assembly 101 is used to limit the length of the support column 10. The locking assembly 101 can be a switch of the seventh hydraulic cylinder. The seventh hydraulic cylinder is respectively connected to the two parts of the support column 10 to drive the two parts of the support column 10 to move relative to each other. The locking assembly 101 can also be a pawl, and the pawl is rotatably provided on the lower end part of the support column 10. The upper end part of the support column 10 is provided with a ratchet bar cooperating with the pawl, and the relative position of the two parts of the support column 10 is limited by the pawl and the ratchet bar.

[0084] The trigger assembly 6 is disposed on the second frame assembly 3, preferably on the seventh sub-frame 35. The trigger assembly 6 includes a sixth telescopic cylinder 61 and a trigger member 62. The sixth telescopic cylinder 61 is connected to the trigger member 62 to drive the trigger member 62 to move along the extension direction of the centerline of the second frame assembly 3, so that the trigger member 62 can abut and push the locking assembly 101 to move and can disengage from the locking assembly 101. When the trigger member 62 abuts and pushes the locking assembly 101, the locking assembly 101 is triggered and the length of the support column 10 is locked. When the locking assembly 101 is reset and disengaged from the locking assembly 101, the locking assembly 101 is released, and the length of the support column 10 can be adjusted. The trigger assembly 6 also includes a guide rod 63. The guide rod 63 is disposed on the seventh sub-frame 35 and is arranged along the extension direction of the centerline of the second frame assembly 3. The trigger member 62 is inserted into the guide rod 63 to move under the guidance of the guide rod 63, thereby preventing the trigger assembly 6 and the locking assembly 101 from misalignment.

[0085] It is understandable that, in other embodiments, the installation device of the supporting scaffold may not have the trigger component 6 .
