[0039] The pull-out type electric box according to the present utility model for a rock drill includes an electric box body 11, a fixed support frame 1, a sliding assembly 4, and a sliding support frame 2. In some embodiments, the fixed support frame 1 includes a base 10, two vertical rods 3, and two cross bars. The base 10 is fixedly connected to the rock drill, the two vertical rods 3 are fixedly connected to both sides of the base 10, and the two cross bars including an upper cross bar 5 and a lower cross bar 6 are fixedly connected to the two vertical rods 3. It should be noted that the number of the vertical rods 3 and the cross bars is not limited, and one or more than two vertical rods 3 and cross bars are also possible. Moreover, the connection manner of the base 10, the vertical rods 3, and the cross bars is not limited to fixed connection, and they can be integrally formed in a specific example.

[0040] For the first version of the pull-out type electric box according to the present utility model, the pull-out type electric box further includes a pulley assembly 31. Refer to Figure 1 , Figure 1 is a front view when the fixed support frame 1 and the sliding assembly 4 of the pull-out type electric box according to the first version of the present utility model are in a fixed connection state. In one embodiment, the pulley assembly 31 is fixedly connected to the upper cross bar 5 and is located on one side of the upper cross bar 5. Correspondingly, the sliding assembly 4 is fixedly connected to the lower cross bar 6. In this figure, the sliding assembly 4 is in a locked state.

[0041] For the pull-out type electric box according to the present utility model, the sliding support frame 2 includes an electric box fixing plate 7 for fixedly connecting with the electric box body 11. Refer to Figure 2 and Figure 3 , Figure 2 is a schematic diagram of the electric box fixing plate 7 of the pull-out type electric box according to the present utility model. Figure 3 is a rear view when the electric box body 11 and the sliding support frame 2 of the first version of the pull-out type electric box according to the present utility model are in a fixed connection state. One side of the sliding assembly 4 is fixedly connected to the fixed support frame 1, and the other side is fixedly connected to the sliding support frame 2, so that the fixed support frame 1 and the sliding support frame 2 can be fixedly connected via the sliding assembly 4. As can be seen from Figure 3 , in the first version of the pull-out type electric box according to the present utility model, there is a track 32 on the sliding support frame 2 corresponding to the pulley assembly 31 of the upper cross bar 5 of the fixed support frame 1. As shown in Figure 6 , the pulley assembly 31 can roll along the track 32 when the sliding support frame 2 slides relative to the fixed support frame 1. The track 32 can be made of a metal material such as iron or copper.

[0042] In addition, for the pull-out electrical box according to the present utility model, the sliding support frame 2 further includes a shock-absorbing device 8. Specifically, the shock-absorbing device 8 can be a spring, a shock pad, etc. Four shock-absorbing devices 8 are shown in this example. It should be noted that the number of shock-absorbing devices 8 is not limited to four, and more or fewer shock-absorbing devices 8 are also possible. A corresponding shock-absorbing device mounting member 9 is fixedly provided on the electrical box fixing plate 7, and the shock-absorbing device 8 is mounted to abut against the shock-absorbing device mounting member 9, thereby effectively alleviating the impact of vibration, especially vertical vibration, on the electrical box assembly and the components therein. In addition, the sliding support frame 2 further includes a handle 21 on one side thereof, and the sliding support frame 2 can be easily pulled out from the fixed support frame 1 through the handle 21, thereby increasing the convenience of the pulling operation.

[0043] According to the first version of the pull-out electrical box of the present utility model, Figure 4 and Figure 5 shows a schematic diagram in the locked state after the fixed support frame 1, the sliding support frame 2, the sliding assembly 4 and the electrical box body 11 are fixedly connected, where Figure 4 is a front view of the first version of the pull-out electrical box of the present utility model in the locked state, Figure 5 is a rear view of the first version of the pull-out electrical box of the present utility model in the locked state. It should be understood that the pull-out electrical box is held in the locked state through the locking arrangement of the sliding assembly 4 (detailed below), and at this time, it can be ensured that the electrical box body 11 is in a safe state during both transportation and maintenance.

[0044] In addition, referring to Figure 6 and Figure 7 , Figure 6 is a front view of the first version of the pull-out electrical box of the present utility model in the pulled-out state, Figure 7 is a rear view of the first version of the pull-out electrical box of the present utility model in the pulled-out state. As can be seen from Figure 7 , at this time, the sliding assembly 4 is in the fully pulled-out state, and the sliding assembly 4 has a limiting device 46 (detailed below), whereby the pulling position of the electrical box can be flexibly controlled to meet the usage requirements in different situations. Moreover, during the process of pulling out the sliding support frame 2 and the electrical box body 11 thereon from the fixed support frame 1, the pulley assembly 31 mounted on the upper cross bar 5 of the fixed support frame 1 rolls along the track 32 on the sliding support frame 2, thereby ensuring the smoothness of the pulling operation and reducing the problem of poor sliding caused by excessive dust outside the machine. Compared with the case without the combination of the pulley assembly 31 and the track 32, in the case of having this combination, the total load borne by the sliding assembly 4 can be reduced, and the service life of the sliding assembly 4 can be improved.

[0045] As Figure 8 andFigure 9 As shown Figure 8 is a structural diagram of the sliding assembly 4 of the draw-out electric box according to the present utility model when it is unfolded, Figure 9 is a cross-sectional view of the sliding assembly 4 of the draw-out electric box according to the present utility model when it is fully retracted and locked. The sliding assembly 4 adopted by the present utility model can be purchased from the market. Generally speaking, the sliding assembly 4 includes an outer rail 41, a middle rail 42, an inner rail 43 and balls 44, wherein the outer rail 41 is fixedly connected to the cross bar of the fixed support frame 1, the middle rail 42 is embedded within the outer rail 41 and forms a sliding connection with the outer rail 41 through the balls 44, the inner rail 43 is embedded within the middle rail 42 and forms a sliding connection with the middle rail 42 through the balls 44, and the inner rail 43 is fixedly connected to the sliding support frame 2.

[0046] In addition, the sliding assembly 4 further includes a lever 45 and a limiting device 46. The limiting device 46 is installed near the ends of the middle rail 42 and the inner rail 43 close to the outer rail 41, and is used to abut against the corresponding stop portions on the middle rail 42 and the outer rail 41 when the sliding assembly 4 is fully pulled out, so that the sliding assembly 4 cannot slide. When the lever 45 is pressed down, the limiting device 46 disengages from the stop portion, enabling the outer rail 41 and the inner rail 43 to slide.

[0047] In addition, the sliding assembly 4 has a locking arrangement, which is realized through a specific structure at the ends of the outer rail 41, the middle rail 42 and the inner rail 43 of the sliding assembly 4. When the middle rail 42 and the inner rail 43 are fully retracted within the outer rail 41, this locking arrangement can lock the middle rail 42 and the inner rail 43 so that they cannot slide, and pressing down the lever 45 can release this locking.

[0048] Refer to Figure 10 , Figure 10 is a rear view of the second version of the draw-out electric box according to the present utility model. In this second version of the draw-out electric box according to the present utility model, the sliding assembly 4 is fixedly connected to the upper cross bar 5 of the fixed support frame 1, while the pulley assembly 31 is fixedly connected to the lower cross bar 6 of the fixed support frame 1. Compared with the previously described draw-out electric box, this arrangement can greatly reduce the load borne by the sliding assembly 4, and can avoid the sliding obstruction of the sliding assembly 4 due to dust and rain, making the drawing of the electric box smoother.

[0049] Refer to Figure 11 , Figure 11It is the rear view of the third version of the pull-out electric box according to the present utility model. In this third version of the pull-out electric box according to the present utility model, sliding components 4 are fixedly connected to both the upper cross bar 5 and the lower cross bar 6 of the fixed support frame 1, but only one of these two locking components has a locking arrangement, so that the situation of asynchronous locking will not occur. In this arrangement, since there are two sliding components 4 to bear the load of the electric box body 11, the service life of the sliding components 4 can be further improved, and when one of the sliding components 4 has a problem, it will be more convenient to replace.

[0050] The pull-out electric box according to the present utility model can be pulled out from the fixed support frame 1 by adopting the sliding components 4, so that the problems of narrow space and difficult maintenance during debugging and repair can be overcome. In addition, the sliding components 4 of the pull-out electric box according to the present utility model have a locking arrangement, which can ensure that the electric box is in a safe state during both transportation and maintenance. In addition, the sliding components 4 of the pull-out electric box according to the present utility model have a three-stage structure and a limiting device 46, whereby the pulling position of the electric box can be flexibly controlled to meet the usage requirements in different situations.

[0051] Moreover, the pull-out electric box according to the present utility model can reduce the problem of poor sliding caused by excessive external dust by adopting the pulley assembly 31 and the corresponding track 32, and can effectively make up for the problem of dust restriction suffered in the case of only having the sliding components 4. In addition, the pull-out electric box according to the present utility model can effectively relieve the influence of vibration on the electric box assembly and the components therein by adopting the shock absorption device 8. Finally, the pull-out electric box according to the present utility model increases the convenience of the pulling operation by adopting a handle design.

[0052] The present utility model and its embodiments are schematically described above. This description is not restrictive, and what is shown in the drawings is only one of the embodiments of the present utility model, and the actual structure is not limited thereto. Therefore, if those of ordinary skill in the art are inspired by it and design similar structural modes and embodiments without creative work without departing from the creative purpose of the present utility model, they shall fall within the protection scope of the present utility model.
