Description

Technical Field

[0001] This application relates to the technical field of tunnel engineering equipment, and particularly to a detachable hanging basket, a rock drilling boom, and a rock drilling jumbo. Background Art

[0002] Currently, due to the requirements of the tunneling drilling operation range, fixed hanging baskets are generally not configured on the rock drilling booms of tunneling rock drilling jumbos. To solve the problem of using a lifting platform for placing explosives after drilling, a method of configuring an arch jumbo is mostly adopted. In some construction sites, in order to reduce the number of times the jumbo enters and exits the site, a simple hanging basket is hung on the propulsion main beam of the rock drilling jumbo to carry out the work of placing explosives.

[0003] When using an arch jumbo for charging operations, different equipment needs to enter and exit the site multiple times, which takes a long time. Especially when carrying out construction operations in a long tunnel, currently, two methods of hanging a simple hanging basket on the propulsion main beam of the existing rock drilling jumbo can be considered. The first is a simple hanging basket made on-site at the construction site, which is hung on the side wall of the propulsion main beam with a concave cross-section using a hook. This method is only applicable to rock drilling jumbos with relatively gentle boom movements due to the lack of limit. There is a great risk of the hanging basket unhooking and falling during sudden jolts or rotation of the rock drilling mechanism. At the same time, because the propulsion main beam is fixed on the bracket of the rock drilling boom by a pressing block, it will be continuously worn during use, increasing the gap between the pressing block and the propulsion main beam. There is a risk of the side-hung hanging basket pressing the propulsion main beam off the track and falling if the pressing situation of the pressing block is not checked in time. The second is to install a bracket on the propulsion main beam to fix the hanging basket on the bracket. This method can avoid the risk of unhooking and falling in the first method, but still cannot avoid the risk of pressing the propulsion main beam off the track. Therefore, both of these two methods have a risk of slipping when the hanging basket is used in conjunction with the propulsion main beam on the rock drilling jumbo, posing a safety hazard. In addition, in both of these two methods, the hanging basket is arranged at the front end of the propulsion main beam, and the hanging basket is far from the boom. During the movement of the boom, the shaking of the boom and the hanging basket is very large, posing a great safety hazard. Summary of the Utility Model

[0027] Embodiment 1

[0028] Referring to Figure 1 - Figure 2 , this embodiment provides a detachable hanging basket, including a hanging basket assembly 100, a connection assembly 200, and a connection seat 300. The hanging basket assembly 100 is used to carry staff; the connection assembly 200 is connected to the bottom of the hanging basket assembly 100; the connection seat 300 is connected to the bottom of the propulsion main beam 400, and the connection assembly 200 is detachably connected to the two side walls of the connection seat 300, so that the hanging basket assembly 100 is suspended above the propulsion main beam 400.

[0029] In this embodiment, the hanging basket assembly 100 can be supported above the propulsion main beam 400 through the connection assembly 200. The connection assembly 200 is connected to both side walls of the connection seat 300 across the propulsion main beam 400, that is, the support stress point is located on the connection seat 300 at the bottom of the propulsion main beam 400, so that the hanging basket assembly 100 can be suspended above the propulsion main beam 400. Then, the hanging basket assembly 100 does not need to act directly on the propulsion main beam 400. Therefore, in this embodiment, the fixed position of the hanging basket assembly 100 is set on the connection seat 300 instead of the propulsion main beam 400, which can effectively reduce the risk of safety accidents caused by the slipping of the hanging basket assembly 100.

[0030] As an alternative embodiment, the connection assembly 200 includes a support arm 210, a first fastener 220, a support frame 230, and a second fastener 240. The support arm 210 is connected to the bottom of the hanging basket assembly 100 and straddles both sides of the propulsion main beam 400; the first fastener 220 penetrates through the bottom of the support arm 210 and the connection seat 300 at the same time; the support frame 230 is connected to the bottom of the hanging basket assembly 100 and straddles both sides of the propulsion main beam 400; the second fastener 240 penetrates through the bottom of the support frame 230 and the connection seat 300 at the same time.

[0031] In this embodiment, both the support arm 210 and the support frame 230 play a role in supporting the hanging basket assembly 100. During installation, the support arm 210 and the support frame 230 straddle both sides of the propulsion main beam 400, and then the first fastener 220 passes through the preset installation holes on the support arm 210 and the connection seat 300, and at the same time, the second fastener 240 passes through the preset installation holes on the support frame 230 and the connection seat 300, so as to complete the rapid assembly and subsequent disassembly. By using a detachable hanging basket, the charging function of the rock drilling jumbo can be realized, and removing the hanging basket during drilling will not affect the drilling operation.

[0032] As an alternative embodiment, the connection assembly 200 further includes a third fastener 250. The top of the support frame 230 is detachably connected to the bottom of the hanging basket assembly 100 through the third fastener 250. Therefore, the support frame 230 can be detached separately, which is convenient for installation and subsequent storage and folding. Similarly, the support arm 210 can also be detachably connected to the bottom of the hanging basket assembly 100 through the corresponding fastener, further improving the storage and folding.

[0033] It should be noted that the above first fastener 220, second fastener 240, and third fastener 250 can all adopt fasteners such as pins and bolts, or other fasteners that can be quickly installed and disassembled.

[0034] As an alternative embodiment, a ceiling assembly 500 is provided on the hanging basket assembly 100. The ceiling assembly 500 includes a telescopic frame 510, a protective shed 520 and a support rod 530. The telescopic frame 510 is connected to the side wall of the hanging basket assembly 100; the protective shed 520 is hinged to the top of the telescopic frame 510; the support rod 530 is detachably connected between the bottom surface of the protective shed 520 and the side wall of the telescopic frame 510.

[0035] In this embodiment, the support rod 530 serves to support the protective shed 520 to a horizontal state, and the protective shed 520 serves to block falling objects from hitting the staff inside the hanging basket assembly 100. The protective shed 520 can be lifted and lowered by the telescopic frame 510, so as to make adaptive adjustments according to actual usage requirements. In the case where the hanging basket assembly 100 needs to be close to the top of the cave for operation, the support rod 530 can be removed, and then the protective shed 520 is turned downward, and the protective shed 520 is lowered through the telescopic frame 510, so as to fold the protective shed 520 inside the hanging basket assembly 100, preventing interference between the protective shed 520 and the top of the cave, and also facilitating transportation and storage. Therefore, the liftable and foldable ceiling assembly 500 adopted in this embodiment can effectively prevent falling objects from hurting people, and at the same time is convenient for storage and does not occupy space.

[0036] As an alternative embodiment, the telescopic frame 510 includes a fixed pipe 511, a movable rod 512 and a limiting structure. The fixed pipe 511 is connected to the side wall of the hanging basket assembly 100; the movable rod 512 movably passes through the fixed pipe 511, and the protective shed 520 is hinged to the top of the movable rod 512; the limiting structure is used to fix the movable rod 512 at different height positions on the fixed pipe 511.

[0037] In this embodiment, when performing lifting adjustment, the fixing effect of the limiting structure is released, so that the movable rod 512 can slide up and down in the fixed pipe 511. After sliding to the corresponding position, the movable rod 512 is fixed on the fixed pipe 511 through the limiting structure. When the protective shed 520 needs to be stored, the movable rod 512 is directly lowered to the bottom inside the hanging basket assembly 100.

[0038] It should be noted that the telescopic frame 510 can also adopt an automatic telescopic mechanism, such as using a telescopic oil cylinder or an electric push rod to achieve the function of automatic lifting.

[0039] As an alternative embodiment, the limiting structure includes a first positioning hole 513, a plurality of second positioning holes 514 and a limiting pin. The first positioning hole 513 is opened on the fixed pipe 511; the plurality of second positioning holes 514 are opened on the movable rod 512, and the plurality of second positioning holes 514 are vertically distributed; the limiting pin is used to penetrate the first positioning hole 513 and the second positioning hole 514 at the corresponding height to fix the movable rod 512 at different height positions on the fixed pipe 511.

[0040] In this embodiment, during adjustment, the first positioning hole 513 on the fixed tube 511 cooperates with the second positioning holes 514 at different height positions on the movable rod 512. Then, by passing a limit pin through the first positioning hole 513 and the corresponding second positioning hole 514 at the appropriate height, the movable rod 512 can be quickly fixed at different height positions on the fixed tube 511, and at the same time, it is convenient for subsequent disassembly, with convenient and fast operation.

[0041] It should be noted that other structures that are convenient for fixing and disassembling can also be used for the limit structure here, such as spring buckles, snap fasteners, etc.

[0042] As an alternative embodiment, both ends of the support rod 530 are detachably connected to the protective shed 520 and the telescopic frame 510 respectively through pin shafts; or, one end of the support rod 530 is hinged to the bottom surface of the protective shed 520, and the other end of the support rod 530 is detachably connected to the side wall of the telescopic frame 510 through a pin shaft; or, one end of the support rod 530 is hinged to the side wall of the telescopic frame 510, and the other end of the support rod 530 is detachably connected to the bottom surface of the protective shed 520 through a pin shaft.

[0043] In this embodiment, both ends of the support rod 530 can be detachably connected to the protective shed 520 and the telescopic frame 510 respectively through pin shafts, so as to facilitate the overall disassembly of the support rod 530; or a connection method where one end of the support rod 530 is detachable and the other end is hinged can also be adopted. When the protective shed 520 needs to be stored, the detachable end of the support rod 530 is removed from the side wall of the telescopic frame 510 or the bottom surface of the protective shed 520, and then the support rod 530 can be rotated and folded for storage. The support rod 530 is always hung on the telescopic frame 510 or the protective shed 520, which can reduce the risk of loss due to improper storage after the overall disassembly of the support rod 530.

[0044] As an alternative embodiment, the hanging basket assembly 100 includes a carrying platform 110 and a protective railing 120, and the connecting assembly 200 is connected to the bottom of the carrying platform 110; the protective railing 120 is arranged on the top of the carrying platform 110, and the telescopic frame 510 is connected to the side wall of the protective railing 120.

[0045] In this embodiment, the staff stands on the carrying platform 110 for easy operation. The protective railing 120 plays a safety protection role. The protective railing 120 has a gate or an opening with a protective chain, which is convenient for the staff to enter and exit.

[0046] Embodiment 2

[0047] Refer to Figure 1 - Figure 2, this embodiment provides a rock drilling boom, which includes the above-mentioned detachable hanging basket. The propulsion main beam 400 is a part of the rock drilling boom. Since the hanging basket assembly 100 is connected through the connecting seat 300 at the bottom of the propulsion main beam 400, not only can the charging function of the rock drilling jumbo be realized, but removing the hanging basket during drilling will not affect the drilling operation. Moreover, setting the fixed position on the connecting seat 300 instead of the propulsion main beam 400 can effectively avoid the risk of casualties caused by the hanging basket slipping off the propulsion main beam 400.
