Description

Technical Field

[0001] The utility model relates to the field of mining equipment, in particular to a special protective device for an anchor bolt machine. Background Art

[0002] Anchor bolters are widely used in mine support operations. The principle is: the drill bit at the front end is driven pneumatically or hydraulically to drill holes in the roof of the mine room for inserting anchor bolts, so that the anchor bolts can be fixed to the roof of the mine room and play a supporting role.

[0003] However, most existing bolting machines do not have a special protective design and cannot effectively protect the operator's head. When the bolting machine is lifted up and turned upside down for drilling operations, the generated gravel and sand are easy to fall directly and hit the operator's head and face, which will not only dirty the operator's head and face, but also cause impact injuries to the operator with larger gravel, posing a major safety hazard.

[0004] Based on the above problems, they can be solved by adding a protective cover around the drill bit. However, a closed protective cover is not practical. When the protective cover is full of gravel, the operation needs to be stopped immediately and the gravel in the protective cover needs to be dumped. The efficiency of the drilling top operation is low, and the operators' dumping of gravel back and forth also increases the workload. Utility Model Content

[0032] The protective plate 2 is provided with a plurality of discharge troughs equidistantly around, and a discharge baffle 201 is correspondingly installed on the outer side of the discharge trough. The bottom of the discharge baffle 201 is rotatably connected to the bottom of the protective plate 2, and the discharge baffle 201 can be turned downward and opened relative to the bottom of the protective plate 2. The discharge trough is rectangular, and the corresponding discharge baffle 201 on the outer side of the discharge trough is also rectangular, and the area of ​​the discharge baffle 201 is larger than the area of ​​the discharge trough. By setting the discharge trough and the discharge baffle 201 in coordination, it is possible to realize the top drilling operation and the dumping of the gravel at the same time, without stopping the top drilling operation in the middle and then dumping the gravel, which improves the work efficiency of the top drilling operation and reduces the workload of the operators.

[0033] The lower side of the protective plate 2 is provided with a push positioning assembly 3, which is slidably connected to the pneumatic assembly 1, and the top of the push positioning assembly 3 abuts against the outer side of the discharge baffle 201 to control the opening and closing of the discharge baffle 201. By providing the push positioning assembly 3, the convenience of dumping gravel is improved, and at the same time, a supporting force is provided for the discharge baffle 201, thereby enhancing the stability of the protective function of the protective plate 2.

[0034] The upper part of the pneumatic assembly 1 is horizontally surrounded by an annular hand-grabbing wheel 102, and a plurality of connecting rods for limiting the push positioning assembly 3 are arranged between the hand-grabbing wheel 102 and the pneumatic assembly 1. The hand-grabbing wheel 102 is provided to facilitate the manual operation of the operator, thereby improving the convenience of the operation of the device; it can also limit the push positioning assembly 3, so that the upper limit of the movement of the push positioning assembly 3 does not exceed the position of the hand-grabbing wheel 102, so as to better control the moving distance of the push positioning assembly 3, thereby controlling the opening and closing of the discharge baffle 201 more quickly and efficiently.

[0035] like Figure 4 and Figure 5As shown, the push positioning assembly 3 includes a semicircular connecting ring 301 for sleeved on the outside of the pneumatic assembly 1, a jacking bolt is horizontally arranged on the semicircular connecting ring 301, and a positioning hole is arranged on the pneumatic assembly 1. The jacking bolt corresponds to the positioning hole and is plugged in and matched to achieve the fixation of the push positioning assembly 3 and the pneumatic assembly 1. By providing the jacking bolt to cooperate with the positioning hole, the push positioning assembly 3 can better maintain the closure of the discharge baffle 201 when there is no need to dump the gravel, and further improve the stability of the protective function of the protective plate 2.

[0036] L-shaped vertical support push rods 302 are vertically welded upward at both ends of the semicircular connecting ring 301, and two vertical positioning sleeves 105 are symmetrically provided on the side wall of the pneumatic component 1.

The diameter of the horizontal support ring is larger than the diameter of the semicircular connecting ring 301 and smaller than the diameter of the hand grab wheel 102. The horizontal support ring is located at the lower side of the hand grab wheel 102. A number of vertical support top shafts 303 are provided on the horizontal support ring. Each vertical support top shaft 303 vertically passes through the gap between the corresponding adjacent connecting rods upward. A guide wheel is provided at the top end of each vertical support top shaft 303. The guide wheels correspond to the unloading baffle 201 one by one. Each guide wheel is in sliding contact with the outer wall of the corresponding unloading baffle 201, and the opening and closing of the unloading baffle 201 is controlled by sliding the guide wheel.

[0038] The utility model discloses a special protective device for an anchor bolt machine, and its use method is as follows:

[0039] When the bolter is drilling, the operator holds the operating handle 101 and the hand wheel 102 with both hands to keep stable during the operation. The tightening bolts are inserted and fixed into the positioning holes to keep the discharge baffle 201 stable and closed to receive the gravel and sand falling from above. The pneumatic assembly 1 is started to provide the rotary drilling assembly 104 with power to drill upward. At this time, the gravel and sand generated by the drilling operation all fall into the protective plate 2.

[0040] After the top drilling operation has been carried out for a period of time, the operator removes the jacking bolt from the positioning hole so that the jacking positioning assembly 3 and the pneumatic assembly 1 are no longer relatively fixed, and slides the jacking positioning assembly 3 downward along the pneumatic assembly 1. When the guide wheel moves to the bottom of the protective plate 2, the unloading baffle 201 flips down and opens, and the gravel and sand in the protective plate 2 are unloaded from the unloading chute, completing the work of cleaning the waste stone in the protective plate 2. Slide the jacking positioning assembly 3 upward along the pneumatic assembly 1 again until the upper limit (the horizontal support ring is tightly attached to the hand-grabbing wheel 102). At this time, all the unloading baffles 201 are tightly closed on the protective plate 2, and the jacking bolts are plugged and fixed to the positioning holes again, and the protective plate 2 is restored to continue to remain in a closed state to receive gravel and sand.

[0041] When downward drilling is required (no protection is required), the protection plate 2 can be removed from the mounting flange 103 by rotating the screws.
