Description

Technical Field

[0001] This utility model belongs to the field of tunnel support technology, and more specifically, it relates to a support device and mining equipment. Background Technology

[0002] In tunnel excavation, support devices are installed on bolt drilling rigs and used in tunnel excavation. Bolt drilling rigs are mechanical equipment used in tunnel excavation. During tunnel excavation, ground collapse is a common danger. When bolt drilling rigs are drilling, the support devices can effectively support the ground around the tunnel to prevent ground collapse and ensure the stability of the tunnel, thereby ensuring the safety of workers.

[0003] The existing anchor bolt drilling rigs have support structures that extend in one direction (left and right) for lateral support; they lack the ability to extend in the front and back directions, resulting in a very small longitudinal support range. Some mining equipment is equipped with face support devices, but these devices can only extend forward and cannot extend the longitudinal support range backward. Utility Model Content

[0004] The existing anchor bolt drilling rig's support structure extends only to the left and right for lateral support, lacking the ability to extend forward and backward, resulting in a very small longitudinal support range. While some mining equipment is equipped with face support devices, these devices can only extend forward and cannot extend the longitudinal support range backward. The purpose of this invention is to provide a support device installed on mining equipment. This support device includes: a telescopic arm, a swinging part, and a top support assembly. The top support assembly is mounted above the telescopic arm via the swinging part. The top support assembly includes: a first support frame, a second support frame, and a third support frame. The first support frame is connected to the swinging part, and two second support frames are symmetrically arranged at both ends of the first support frame. The first support frame can move the two second support frames away from each other. The third support frame is rotatably connected to both ends of the second support frames to expand the support area of ​​the second support frames along the length or width direction.

[0005] Furthermore, the two ends of the first support frame are respectively connected to the middle of the second support frame to form an I-shaped support structure; the third support frame includes a hinged end and a free end, the hinged end is hinged to the end of the second support frame, and the free end can rotate around the hinged end.

[0006] Furthermore, when the free end rotates to the first position, the extension direction of the third support frame is the length direction of the second support frame, and the third support frame is located outside the second support frame.

[0007] Furthermore, when the free end rotates to the second position, the extension direction of the third support is the width direction of the second support, and the third support is located outside the second support.

[0008] Furthermore, when the free end rotates to the third position, the extension direction of the third support is the width direction of the second support, and the third support is located inside the second support.

[0009] Furthermore, the first support frame includes a first telescopic inner cylinder, a first telescopic outer cylinder, and a first driving component. The first telescopic inner cylinder is disposed inside the first telescopic outer cylinder, and the first driving component can drive the first telescopic inner cylinder to extend or retract into the first telescopic outer cylinder.

[0010] Furthermore, the support device also includes: an arched support frame, disposed on one side of the first support frame and connected to the first support frame; wherein the top of the arched support frame is arc-shaped.

[0011] Furthermore, the support device also includes a second telescopic part, disposed below the arched support frame, and driven to connect to the arched support frame.

[0012] Furthermore, the second telescopic part includes: a second telescopic inner cylinder, a second telescopic outer cylinder, and a second driving member. The second telescopic inner cylinder is disposed inside the second telescopic outer cylinder, and the second driving member can drive the second telescopic inner cylinder to extend or retract into the second telescopic outer cylinder.

[0013] Furthermore, this application provides a mining equipment that uses any of the support devices described above.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. Since the third support frame is connected to both ends of the second support frame, it can extend the longitudinal support range forward via the front end of the second support frame, and it can also extend the longitudinal support range backward via the rear end of the second support frame. Because the third support frame is rotatably connected to the second support frame, it can also be rotated to the left and right, extending the lateral support range to the left and right. Construction personnel can adjust the position of the third support frame according to construction needs to extend the support range of the second support frame along its length or width, that is, to extend the longitudinal or lateral support range of the top support assembly.

[0016] 2. When the free end rotates to the first position, the extension direction of the third support frame is the length direction of the second support frame, and the third support frame is located outside the second support frame. At this time, the third support frame at the front end of the second support frame extends the longitudinal support range forward, and the third support frame at the rear end of the second support frame extends the longitudinal support range backward. The longitudinal support range of the support device is the sum of the length of the second support frame and the lengths of the two third support frames.

[0017] 3. When the free end rotates to the second position, the extension direction of the third support frame is the width direction of the second support frame, and the third support frame is located outside the second support frame. At this time, the third support frame on the left side of the second support frame extends the lateral support range to the left, and the third support frame on the right side of the second support frame extends the lateral support range to the right. The lateral support range of the support device is the sum of the length of the first support frame, the width of the two second support frames, and the length of the two third support frames.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0029] See Figure 1 This is a structural schematic diagram of a support device 100 provided by this utility model. Combined with... Figures 1 to 8 The support device 100 is installed on the mining equipment and includes: a telescopic arm 10, a swinging part 20, and a top support assembly 30. The top support assembly 30 is installed above the telescopic arm 10 via the swinging part 20. The swinging part 20 can adjust the left and right angles of the top support assembly 30 to adapt to the left and right slopes of the roadway. For example, the swinging part 20 is a swing seat located below the top support assembly 30. The swing seat includes an upper mounting plate, a lower mounting plate, and two adjusting springs located between the upper and lower mounting plates. When there is a left and right slope in the roadway roof, the compression of one adjusting spring will be greater than the compression of the other adjusting spring, thereby adjusting the left and right angles of the upper mounting plate, and thus adjusting the left and right angles of the top support assembly 30 installed above the swinging part 20.

[0030] Specifically, the top support assembly 30 includes a first support frame 31, a second support frame 32, and a third support frame 33; support nets can be placed on the first support frame 31, the second support frame 32, and the third support frame 33. The first support frame 31 is connected to the upper mounting plate of the swing part 20, and the two second support frames 32 are symmetrically arranged at both ends of the first support frame 31. When the top temporary support assembly is deployed, the length of the first support frame 31 extends, and the first support frame 31 drives the two second support frames 32 away from each other. When the top temporary support assembly is deployed, the length of the first support frame 31 extends, and the first support frame 31 drives the two second support frames 32 away from each other to the deployed state. At this time, the lateral support range of the top support assembly 30 is the length of the first support frame 31 plus the width of the two second support frames 32; the longitudinal support range of the top support assembly 30 is the length of the second support frame 32. When the top temporary support assembly is retracted, the length of the first support frame 31 is shortened, and the first support frame 31 drives the two second support frames 32 to move closer to each other until they are in a retracted state.

[0031] Furthermore, the third support frame 33 is rotatably connected to both ends of the second support frame 32 to expand the support area of ​​the second support frame 32 along the length or width direction. For example, the third support frame 33 is an auxiliary support frame set at both ends of the second support frame 32. Construction personnel can adjust the position of the third support frame 33 according to construction needs to expand the support range of the second support frame 32 along the length or width direction, that is, to expand the longitudinal or transverse support range of the top support assembly 30.

[0032] Since the third support frame 33 is connected to both ends of the second support frame 32, it can extend the longitudinal support range forward through the front end of the second support frame 32, and it can also extend the longitudinal support range backward through the rear end of the second support frame 32. Because the third support frame 33 is rotatably connected to the second support frame 32, it can also rotate to the left and right directions to extend the lateral support range to the left and right.

[0033] It should be noted that the existing anchor bolt drilling rig's support structure can only extend in one direction (left or right) for lateral support; it lacks the ability to extend in the front-back direction, resulting in a very limited longitudinal support range. Although some mining equipment is equipped with a face support device 100, this face support device 100 can only extend forward and cannot extend the longitudinal support range backward.

[0034] In this application, the support device 100 can expand the support range in the front, back, left, and right directions by adjusting the position of the third support frame 33.

[0035] Furthermore, the two ends of the first support frame 31 are respectively connected to the middle of the second support frame 32 to form an I-shaped support structure; the third support frame 33 includes a hinged end and a free end, the hinged end is hinged to the end of the second support frame 32, and the free end can rotate around the hinged end.

[0036] Furthermore, when the free end rotates to the first position, the extension direction of the third support frame 33 is the length direction of the second support frame 32, and the third support frame 33 is located outside the second support frame 32. At this time, the third support frame 33 at the front end of the second support frame 32 extends the longitudinal support range forward, and the third support frame 33 at the rear end of the second support frame 32 extends the longitudinal support range backward. The longitudinal support range of the support device 100 is the sum of the length of the second support frame 32 and the lengths of the two third support frames 33.

[0037] Furthermore, when the free end rotates to the second position, the extension direction of the third support frame 33 is the width direction of the second support frame 32, and the third support frame 33 is located outside the second support frame 32. At this time, the third support frame 33 on the left side of the second support frame 32 extends the lateral support range to the left, and the third support frame 33 on the right side of the second support frame 32 extends the lateral support range to the right. The lateral support range of the support device 100 is the sum of the length of the first support frame 31, the width of the two second support frames 32, and the length of the two third support frames 33.

[0038] Furthermore, when the free end rotates to the third position, the extension direction of the third support frame 33 is the width direction of the second support frame 32, and the third support frame 33 is located inside the second support frame 32. At this time, the support device 100 is in a retracted state.

[0039] Furthermore, the first support frame 31 includes a first telescopic inner cylinder, a first telescopic outer cylinder, and a first driving component. The first telescopic inner cylinder is disposed inside the first telescopic outer cylinder, and the first driving component can drive the first telescopic inner cylinder to extend or retract into the first telescopic outer cylinder, thereby adjusting the length of the first support. During support operations, construction personnel can control the first driving component to adjust the length of the first telescopic inner cylinder extending from the first telescopic outer cylinder according to actual construction needs, thereby adjusting the lateral support range of the support device 100 in the left-right direction. Upon completion of the operation, the first telescopic inner cylinder can be retracted into the first telescopic outer cylinder via the first driving component. For example, the first telescopic inner cylinder and the first telescopic outer cylinder are inner and outer square steel structures.

[0040] Furthermore, the support device 100 also includes an arched support frame 34, which is disposed on one side of the first support frame 31, connected to the first support frame 31, and can hold a support net; wherein, the top of the arched support frame 34 is arc-shaped, and the arched support frame 34 is used for support when the top of the roadway is arc-shaped.

[0041] Furthermore, the support device 100 also includes a second telescopic part 341, which is disposed below the arched support frame 34 and is driven to connect to the arched support frame 34 for adjusting the height of the arched support frame 34.

[0042] Furthermore, the second telescopic part 341 includes: a second telescopic inner cylinder, a second telescopic outer cylinder, and a second driving component. The second telescopic inner cylinder is disposed inside the second telescopic outer cylinder, and the second driving component can drive the second telescopic inner cylinder to extend or retract into the second telescopic outer cylinder. During support operations, construction personnel can control the second driving component to adjust the length of the second telescopic inner cylinder extending from the second telescopic outer cylinder according to actual construction needs, thereby adjusting the height of the arched support frame 34; upon completion of the operation, the second telescopic inner cylinder can be retracted into the second telescopic outer cylinder via the second driving component. For example, the second telescopic inner cylinder and the second telescopic outer cylinder are inner and outer square steel structures.

[0043] Furthermore, this application provides a mining equipment that uses any of the support devices 100 described above. For example, the support device 100 is hinged to the front end of the lifting platform of the mining equipment via a telescopic arm 10.
