Description

Technical Field

[0001] The invention relates to the technical field of supporting platforms, and in particular to a drilling and blasting platform frame. Background Art

[0002] The construction of water diversion hydropower station projects often involves the drilling and blasting of water diversion tunnels of different cross-sectional sizes, and the tunnel drilling and blasting construction is often the key to the construction period. For small-section tunnels, it is usually necessary to set up a drilling and blasting platform in front of the work surface every time, dismantle it after drilling, and re-set it for the next drilling and blasting cycle; for large-section tunnels, it is usually preferred to use single-arm, double-arm or multi-arm hydraulic rock drilling rigs to drill holes to improve work efficiency; in engineering practice, there are more medium-sized tunnels (cross-sectional area 30-50m 2 ), it is more economical to use the drilling and blasting method for construction. The general handheld pneumatic drill blasting platform frame has a single function, a small number of working platforms, and no working platform inside the platform frame. It is impossible to drill holes in the entire section of multiple drilling rigs at the same time, resulting in a long drilling process; some platform main frames are not equipped with hand-held pneumatic drill high-pressure air supply pipes and water supply pipes, which makes drilling inconvenient and the pipelines entangled; some platform frames cannot extend the outer bracket when encountering weak soft interlayers or broken zones, which cannot meet the construction requirements of tunnel section expansion, and need to make a larger platform frame, which increases the cost investment. At the same time, the common drilling and blasting platform frame only considers the space needs of the loader mobile platform frame. The working platform is generally set on the outside of the main frame, and no fixed working platform is set in the "door" frame. Therefore, each time drilling and blasting is performed, it is necessary to temporarily set up an operating platform in the middle of the "door" frame, which not only delays the hole making time but also increases the cost, and fails to solve the contradiction between "platform frame mobile space" and "full section simultaneous drilling and blasting". In addition, when the common drilling and blasting platform is used for spray anchor support, especially when drilling holes with long anchor rods on the top of the cave, the working platform is too close to the rock surface on the top of the cave, making it difficult to drill vertically on the rock surface and the quality cannot be guaranteed. Therefore, the drilling and blasting platform in the prior art has problems such as unreasonable design, more preparation work before drilling, less hand pneumatic drills that can be used for drilling at the same time, and long excavation cycle time. Summary of the invention

[0003] Therefore, the technical problem to be solved by the present invention is to overcome the defects of unreasonable design of drilling and blasting platforms in the prior art, thereby providing a drilling and blasting platform frame with reasonable structure and complete functions.

[0004] In order to solve the above technical problems, the present invention provides a drilling and blasting platform frame, comprising:

[0005] Main frame;

[0006] A working platform, at least partially formed on the main frame and suitable for supporting working personnel and / or working equipment;

[0012] The support portion includes the upper surface of the rotating bracket, and correspondingly, the extension portion includes a movable mesh plate arranged on the upper surface of the rotating bracket;

[0013] The main frame comprises a door-shaped frame, and the door-shaped frame comprises a frame top beam arranged at the top, and frame columns arranged opposite to each other on both sides of the frame top beam;

[0015] The rotating bracket is movably mounted on the frame column.

[0016] The door-type frame further comprises: a frame middle beam, and the frame middle beam is arranged below the frame top beam in the height direction.

[0017] The drilling and blasting platform frame further comprises: a joist, which is arranged at the bottom of the frame top beam and / or the frame middle beam and is suitable for lifting the drilling and blasting platform frame off the ground under the lifting action of the working vehicle;

[0018] When the rotating bracket is in the yielding state, a movable passage is formed under the main frame, which is convenient for loaders and dump trucks to pass under the drilling and blasting platform frame. When the device moves or the dump truck is unloading, the rotating bracket is retracted to meet the passage space requirements of mechanical equipment under the main frame; and when in the working state, the rotating bracket is extended to form a support, which is convenient for forming a working platform, thereby supporting the operating personnel and / or operating equipment;

[0019] The frame middle beam is arranged at the upper position of the rotating bracket in the height direction. The rotating bracket forms a third working platform S3 in the working state. By being made into a plane rotating type, the rotating bracket is pulled open when drilling and blasting is required. After drilling and blasting is completed, the rotating bracket is retracted and fixed to form a traffic space.

[0020] The main frame is also provided with a bracket latch, which is suitable for locking the rotating bracket in a yielding state or an operating state, so as to position the rotating bracket and avoid movement caused by accidental touch.

[0023] The technical solution of the present invention has the following advantages:

[0024] 1. The drilling and blasting platform frame provided by the present invention realizes an organic combination of the two functions of "platform frame moving space" and "full-section simultaneous drilling and blasting" by movably arranging a rotating bracket on the main frame and switching the rotating bracket between a yielding state and an operating state, thereby solving the contradiction and defect of the common drilling and blasting platform frame that cannot simultaneously take into account the passage of mechanical equipment under the main frame and the need to temporarily set up an operating platform in the middle of the tunnel section; and improving the operating efficiency.

[0026] 3. The drilling and blasting platform frame provided by the present invention has a support beam arranged at the bottom of the frame top beam and / or the frame middle beam, so that when the working vehicle moves the drilling and blasting platform frame, it directly contacts the support beam and receives force, thereby avoiding damage to other components, improving the overall contact strength, and ensuring structural safety.

[0040] Combination Figure 1-Figure 4 As shown, the drilling and blasting platform frame provided in this embodiment includes:

[0041] Main frame;

[0042] A working platform, at least partially formed on the main frame and suitable for supporting working personnel and / or working equipment;

[0043] The rotating bracket 7 has one end rotatably connected to the main frame and the other end supported on the ground. The rotating bracket 7 includes a yielding state parallel to the extension direction of the main frame and an operating state set at an angle to the extension direction of the main frame.

[0044] Preferably, the working platform is suitable for supporting working personnel and / or working equipment, wherein the working equipment includes a pneumatic drill 90 .

[0045] A rotatable rotating bracket 7 is arranged at the lower part of the main frame, and the rotating bracket 7 is rotatably connected to the main frame, and in the yielding state, a movable passage is formed under the main frame, which is convenient for loaders and dump trucks to pass under the drilling and blasting platform frame. When the device moves or the dump truck is unloading, the rotating bracket 7 is retracted to meet the passage space requirements of mechanical equipment under the main frame; and in the working state, the rotating bracket 7 is extended to form a support, which is convenient for forming a working platform, thereby supporting the operating personnel and / or operating equipment. By switching the working state, the problems of unreasonable design of the drilling and blasting platform in the existing water diversion tunnel drilling and blasting method excavation, more preparation work before drilling, less hand pneumatic drills that can be used for drilling at the same time, and long excavation cycle are solved.

[0046] The drilling and blasting platform frame provided in this embodiment realizes the organic combination of the two functions of "platform frame moving space" and "full-section simultaneous drilling and blasting" by movably arranging the rotating bracket 7 on the main frame and switching the rotating bracket 7 between the yielding state and the working state, thereby solving the contradiction and defect of the common drilling and blasting platform frame between the inability to simultaneously take into account the passage of mechanical equipment under the main frame and the need to temporarily set up an operating platform in the middle of the tunnel section, and improving the working efficiency.

[0047] Preferably, the drilling and blasting platform frame provided in this embodiment is mainly used in tunnels, and is particularly suitable for use in medium-section water diversion tunnels. When the drilling and blasting platform frame is in an operating environment, the length direction of the main frame is parallel to the extension direction of the tunnel, and the width direction of the main frame is perpendicular to the extension direction of the tunnel and parallel to the horizontal plane. Among them, the length direction of the main frame is the extension direction of the main frame.

[0048] Specifically, the main frame includes a door-type frame, and the door-type frame includes a frame top beam 2 arranged at the top, and frame columns 1 arranged opposite to each other on both sides of the frame top beam 2;

[0050] The rotating bracket 7 is movably mounted on the frame column 1 .

[0051] Preferably, a steel mesh is laid on the upper part of the frame top beam 2 to form a first working platform S1. The steel mesh is welded into multiple pieces to facilitate manual movement and paving, and the meshes are tied tightly with lead wire.

[0052] Specifically, the portal frame further includes: a frame middle beam 12 , and the frame middle beam 12 is arranged below the frame top beam 2 along the height direction.

[0053] A frame middle beam 12 is arranged directly below the frame top beam 2 of the drilling and blasting platform frame to form a second working platform S2. The frame top beam 2 and the frame middle beam 12 are welded and connected via a top beam middle beam connecting column 11. Preferably, reinforcing beams 13 are welded at both ends of the lower part of the frame middle beam 12 to improve the structural strength.

[0054] Additionally, by arranging a pneumatic drill 90 with a long drill rod 91 on the second working platform S2, the second working platform S2 can also serve as a long anchor hole making working platform on the cave roof.

[0055] In the prior art, when the drilling and blasting platform is generally used for drilling holes with long anchor rods on the top of the cave, the top working platform is too close to the rock wall 70, making it impossible to drill holes vertically and the quality is difficult to guarantee. Figure 3 As shown, the drilling and blasting platform frame provided in this embodiment can also be used as a sprayed anchor support work platform. The focus of the sprayed anchor support is the 120-degree range of the cave roof arch. When long anchor rods need to be installed on the cave roof for support, since the first working platform S1 is too close to the rock wall, it is difficult to implement anchor rod drilling and it is also difficult to ensure the quality. At this time, the staff can drill holes on the second working platform S2, and the first working platform S1 can also play a protective role.

[0056] The drilling and blasting platform frame provided in this embodiment forms a second working platform S2 by setting a frame middle beam 12 under the frame top beam 2, so that the second working platform S2 can also serve as a sprayed anchor support working platform, which can adapt to rock anchoring construction at any angle within 120 degrees of the cave top, especially long anchor drilling construction, so as to achieve multiple uses of one frame and avoid repeated production of working platforms with different functions, resulting in waste and mutual interference.

[0057] Preferably, the frame middle beam 12 is arranged above the rotating bracket 7 in the height direction. The rotating bracket 7 forms a third working platform S3 in the working state.

After the drilling and blasting are completed, the rotating bracket 7 is retracted and fixed to form a traffic space.

[0058] Preferably, a bracket latch 8 is also provided on the main frame, and the bracket latch 8 is suitable for locking the rotating bracket 7 in a yielding state or an operating state, so as to position the rotating bracket 7 and avoid movement caused by accidental touch.

[0059] Preferably, in this embodiment, a frame bottom beam 3 is welded to the bottom of each of the four frame columns 1 on both sides of the portal frame, and the frame bottom beam 3 is in contact with the ground to bear force. A total of three longitudinal beams are welded to the middle and upper parts of the frame columns 1, and the bottom beam, longitudinal beams and portal frame together form a main frame.

The bracket latch 8 is welded to the inner side of the frame column 1 of the door-shaped frame, and a total of 4 pairs of 8 pieces of devices are set. The columns and top beams on both sides of the rotating bracket 7 are welded by channel steel.

[0061] Specifically, the drilling and blasting platform frame further includes: a support beam 10, which is arranged at the bottom of the frame top beam 2 and / or the frame middle beam 12, and is suitable for lifting the drilling and blasting platform frame off the ground under the jacking action of the work vehicle 80.

[0062] Preferably, in this embodiment, the support beam 10 is welded to the bottom of the frame center beam 12 .

[0063] The drilling and blasting platform frame provided in this embodiment is provided with a support beam 10 at the bottom of the frame top beam 2 and / or the frame middle beam 12, so that when the working vehicle 80 moves the drilling and blasting platform frame, it is directly in contact with the support beam 10 and receives force, thereby avoiding damage to other components, improving the overall contact strength, and ensuring the safety of the structure.

[0064] Preferably, the working vehicle 80 may be a loader.

[0065] Specifically, the working platform includes: a supporting part and an extension part arranged on the supporting part; the supporting part is directly or indirectly arranged on the main frame and supports the extension part; the extension part is suitable for increasing the area of ​​the working area under the supporting state of the supporting part.

Therefore, the folding mesh plate 14 is made to be foldable around the folding axis 15, spread out when in use, and folded up when not in use. Therefore, when the drilling and blasting platform frame moves, it is retracted inwardly along with the sleeve beam to avoid collision with cave wall facilities, thereby improving overall flexibility.

A single steel mesh plate is welded by round steel with a diameter of 6-8 mm and angle steel.

A four-layer working platform is formed according to the cross-sectional size of the medium-sized water diversion tunnel, and more than 10 hand drills can be organized to drill holes in the entire section at the same time, which greatly improves work efficiency and reduces the drilling and blasting cycle time.
