Description

Technical Field

[0001] The utility model belongs to the technical field of scaffolding support, and more specifically relates to a movable beam opening device for scaffolding support. Background Art

[0002] During coal mining operations, for the personal safety of workers, mining support devices must be continuously added to the excavated mine tunnels. Shed supports are often used for tunnel maintenance to ensure that miners work in a safe environment. Due to the particularity of tunnel support, beam blocks are welded on the shed beams of the shed support outside the tunnel, and then the shed legs are clamped in the beam blocks to provide support during tunnel support. During normal tunnel excavation, the shed top is under great pressure, and the shed beams and shed legs of the shed support in the tunnel will be deformed. Some shed beams will squeeze out the shed beam blocks due to excessive pressure on the side, and the tunnel top cannot be effectively supported. At this time, the shed beams and shed legs need to be removed, and then the shed beams need to be replaced.

[0003] However, since there are many supporting objects on the shed beams and they are under great pressure, after the beam mouth blocks on the shed beams are damaged, dangerous operations such as welding cannot be carried out in the lower tunnels where coal mines are operating. Therefore, the original shed beams can only be removed and replaced with new ones. The whole operation process takes a long time and requires a lot of manpower. The construction process is cumbersome and complicated, the work efficiency is low, and there are many space restrictions in the tunnels, which makes the operation more inconvenient and dangerous.

[0004] Therefore, it is necessary to provide a movable beam opening device for scaffolding support to solve the above-mentioned technical problems. Utility Model Content

[0005] The utility model aims to provide a movable beam opening device for scaffolding support to solve the above technical problems.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A movable beam opening device for shed support, comprising a shed beam and a shed leg, and also comprising:

[0008] Two fixing plates are provided and are arranged at the bottom of both ends of the shed beam;

[0009] A beam mouth component, movably arranged between the shed beam and the shed legs;

[0010] The beam mouth component includes a support plate, on which a U-shaped baffle plate adapted to the shed beam is arranged, and a beam mouth block adapted to the shed leg is arranged at the bottom of the support plate, one side of the U-shaped baffle plate and the beam mouth block are both provided with openings, and the opening directions of the U-shaped baffle plate and the beam mouth block are opposite.

[0011] Furthermore, it also includes:

[0012] A through opening is provided at the front and rear sides of the U-shaped baffle plate, and an abutment plate matched with the fixing plate is provided in the through opening;

[0013] An adjusting hole is provided on the abutting plate, and a limiting hole matching the adjusting hole is provided on the supporting plate.

[0014] Furthermore, a lifting plate is slidably arranged in the through opening, the lifting plate is slidably connected to the abutting plate, and an elastic member is arranged between the lifting plate and the upper wall of the through opening.

[0015] Furthermore, a guide rail is arranged on the lifting plate, a slide groove is provided in the guide rail, and a T-shaped guide plate connected to the abutting plate is slidably arranged in the slide groove.

[0016] Furthermore, a shift groove is provided on the side wall of the through opening, a slider is slidably arranged in the shift groove, and an outer end of the slider is connected to the lifting plate.

[0017] Furthermore, it also includes a threaded hole opened on the U-shaped baffle, an adjusting bolt is threadedly connected to the threaded hole, and an adjusting baffle is arranged at one end of the adjusting bolt located inside the U-shaped baffle.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. In this scheme, the installation of the shed beams and shed legs is realized through the beam mouth components. When the beam mouth blocks on the support plate are squeezed, damaged or fallen off due to the high pressure from the roof of the support frame, a hydraulic rod can be set under the shed beam to temporarily support the shed beam, and then the shed legs can be removed, and then the damaged beam mouth components can be taken away, and then replaced with new beam mouth components and installed on the shed beam to complete the processing process; there is no need to replace new shed beams, which saves costs and avoids the need to remove other objects on the shed beams before replacing the shed beams. Compared with the original processing procedures, the construction procedures are reduced, greatly reducing safety hazards; it also solves the problem of inconvenient operation due to space limitations in the laneway, and the entire processing process saves a lot of time and manpower, shortens the construction period, and greatly improves work efficiency.

[0020] 2. In this solution, after the beam mouth component is installed at the end of the shed beam, the abutment plate can be finally brought into contact with the fixed plate, and then the abutment plate can be fixed on the support plate. At this time, the abutment plate plays a role of abutting the fixed plate, thereby greatly avoiding the situation where the shed beam with a smaller width will be offset in the U-shaped baffle of the beam mouth component, thereby ensuring the subsequent stability of the shed beam and reducing safety hazards. The distance and position of the abutment plate can be adjusted according to different shed beams to meet the needs of various situations.

[0021] 3. In this scheme, after the beam mouth component is installed at the end of the shed beam, the abutment plate can be driven up by the lifting plate, and then the abutment plate can be moved forward and backward to be above the fixed plate. At this time, the entire beam mouth component will be temporarily placed on the end of the shed beam, thereby avoiding the situation where workers have to hold the beam mouth component to stabilize it, making it convenient for the subsequent shed legs to be installed at the beam mouth block, saving time and effort, and further improving the efficiency of installing the shed legs and shed beam supports.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] Embodiment 1:

[0036] See also Figure 1-3 A movable beam mouth device for shed support, comprising a shed beam 1 and a shed leg 2, and also comprising: a fixing plate 3, two of which are arranged at the bottom of both ends of the shed beam 1; a beam mouth component 4, movably arranged between the shed beam 1 and the shed leg 2; the beam mouth component 4 comprises a supporting plate 41, on which a U-shaped baffle plate 42 matched with the shed beam 1 is arranged, and a beam mouth block 43 matched with the shed leg 2 is arranged at the bottom of the supporting plate 41, and one side of the U-shaped baffle plate 42 and the beam mouth block 43 are both provided with openings, and the opening directions of the U-shaped baffle plate 42 and the beam mouth block 43 are opposite.

[0037] When in use, first, when installing the shed beam 1 and the shed leg 2 of the shed support, install the beam mouth component 4 at the end of the shed beam 1, that is, the fixing plate 3 of the shed beam 1 is in contact with the support plate 41, and the shed beam 1 and the fixing plate 3 are in the U-shaped baffle 42, and the inner wall of the U-shaped baffle 42 is in contact with the end of the shed beam 1, and then the upper end of the shed leg 2 is against the bottom of the support plate 41, and the upper end of the shed leg 2 is in the beam mouth block 43. Since the opening directions of the U-shaped baffle 42 and the beam mouth block 43 are opposite, at this time, the shed beam 1 and the shed leg 2 are restricted by the beam mouth block 43, and the U-shaped baffle 42 is restricted by the shed beam 1, so that the installation of the shed beam 1 and the shed leg 2 is achieved. When the beam mouth block 43 on the support plate 41 is squeezed and damaged or falls off due to the high pressure of the support frame roof, it needs to be processed to prevent subsequent safety hazards. At this time, a hydraulic rod can be set up under the shed beam 1 to temporarily support the shed beam 1, so that the shed beam 1 at this position is supported, and then the shed leg 2 can be removed, and then the damaged beam mouth component 4 can be taken away, and then a new beam mouth component 4 can be replaced and installed on the shed beam 1, and then the beam mouth block 43 of the new beam mouth component 4 can be supported by the shed leg 2 to complete the processing process. There is no need to replace the new shed beam 1, which not only saves costs, but also avoids the need to remove other objects on the shed beam 1 before replacing the shed beam 1. Compared with the original processing procedure, the construction process is reduced, and the safety hazards are greatly reduced; it also solves the problem of inconvenient operation due to space limitations in the lane. In addition, the entire processing process saves a lot of time and manpower, reduces construction costs, greatly improves work efficiency, shortens construction period, and improves production benefits.

After the beam mouth component 4 is installed on the end of the shed beam 1, the fixing plate 3 of the shed beam 1 is in contact with the supporting plate 41, and the shed leg 2 is also in the beam mouth block 43 of the beam mouth component 4, and the abutment plate 6 in the through opening 5 of the U-shaped baffle plate 42 can be moved again, that is, the abutment plate 6 is finally in contact with the fixing plate 3, and then the bolt is passed through the adjusting hole 7 on the abutment plate 6 and the limiting hole 8 on the supporting plate 41, and then locked with a nut, so as to fix the abutment plate 6 on the supporting plate 41, that is, the abutment plate 6 at this time plays a role of abutting the fixing plate 3, that is, the abutment plate 6 abuts against the two sides of the end of the shed beam 1, thereby greatly avoiding the shed beam 1 with a smaller width from being offset in the U-shaped baffle plate 42 of the beam mouth component 4, which can ensure the subsequent stability of the shed beam 1 and reduce safety hazards, and the distance position of the abutment plate 6 can be adjusted according to different shed beams 1, which has a wide range of application and strong flexibility and can meet the needs of various situations.

[0040] In this embodiment, preferably, please refer to Figure 5 and Figure 7-9 A lifting plate 9 is slidably arranged in the through opening 5, and the lifting plate 9 is slidably connected to the abutment plate 6. An elastic member 10 is arranged between the lifting plate 9 and the upper wall of the through opening 5, and the elastic member 10 in the present application is a spring.

When the end of the shed beam 1 cannot contact the inner wall of the U-shaped baffle 42 due to the installation position and space of different shed legs 2 and shed beams 1, the adjusting baffle 16 can be driven to move by rotating the adjusting bolt 15, so that the adjusting baffle 16 contacts the end of the shed beam 1, thereby supporting and abutting the end of the shed beam 1, ensuring the stability of the subsequent shed beam 1, and preventing it from moving. And when the adjusting baffle 16 is not needed, it can be removed from the U-shaped baffle 42, and it can be operated according to specific needs.
