[0017] Example 1

[0018] As Figure 1 and Figure 2 shown, a protective formwork for a variable hanging formwork device of the present utility model includes an upper protective formwork 1 and a lower protective formwork 7. A plurality of first tension anchor bolt holes 2 are provided on the upper protective formwork 1, and a plurality of second tension anchor bolt holes 9 are provided on the lower protective formwork 7; the upper protective formwork 1 and the lower protective formwork 7 are detachably connected together; a chute 3 is provided at a position above the side of the upper protective formwork 1, and a plurality of sliders 4 are provided in the chute 3.

[0019] Due to the complex conditions in the coal mine underground, the roadway heights are uneven, and in case of special areas where it is necessary to temporarily add measure holes or adjust the positions of grouting holes, etc., in order to improve the applicability of the automatic hanging formwork device and cope with the complex conditions in the coal mine underground, a protective formwork for a variable hanging formwork device of the present utility model is designed.

[0020] A protective formwork for a variable hanging formwork device of the present utility model is composed of an upper protective formwork 1 and a lower protective formwork 7. Both are installed on the existing automatic hanging formwork device to support the flexible formwork. The upper protective formwork 1 and the lower protective formwork 7 are both made of high-strength steel plates, and their lengths and widths are made according to requirements. A circle of chutes 3 is designed on the upper protective formwork 1, and sliders 4 with a length and width of 400 mm (which can also be other sizes) are movably embedded in the chutes 3. A plurality of anchor bolts are connected between the corresponding plurality of first tension anchor bolt holes 2 and the plurality of second tension anchor bolt holes 9 to further support the flexible formwork. The row spacing between the first tension anchor bolt holes 2 and the second tension anchor bolt holes 9 is set according to the row spacing of the flexible formwork.

[0021] The working principle of the protective formwork for a variable hanging formwork device of the present utility model is as follows: When the conditions in the coal mine underground are normal, only the upper protective formwork 1 is needed for the hanging operation of the flexible formwork. If it encounters a high roof area in the roadway, the upper protective formwork 1 and the lower protective formwork 7 can be connected together. After being fixed, the upper protective formwork 1 and the lower protective formwork 7 are used together for the hanging operation of the flexible formwork. When the construction of the high roof area is completed and reaches the normal area in the coal mine underground, the lower protective formwork 7 can be removed from the upper protective formwork 1, and the upper protective formwork 1 is used for the hanging operation of the flexible formwork. In case of special areas where it is necessary to add measure holes or adjust the positions of grouting holes, the position of the flexible formwork can be exposed by adjusting the position of the moving slider 4, and measure holes can be added on it or grouting holes at appropriate positions can be exposed, so as to realize the connection between the measure holes or grouting holes and the pipelines.

[0022] Obviously, by applying the protective formwork for a variable hanging formwork device of the present utility model to the automatic hanging formwork device, it can ensure that the automatic hanging formwork device can be applicable under various conditions in the coal mine underground.

[0023] Example 2

[0024] AsFigure 1 and Figure 2 As shown in Figure 2 , a form protection plate for a variable hanging form device of the present utility model includes an upper form protection plate 1 and a lower form protection plate 7. A plurality of first tension anchor bolt holes 2 are provided on the upper form protection plate 1, and a plurality of second tension anchor bolt holes 9 are provided on the lower form protection plate 7; the upper form protection plate 1 and the lower form protection plate 7 are detachably connected together; a chute 3 is provided at a position near the upper part of the side surface of the upper form protection plate 1, and a plurality of sliders 4 are arranged in the chute 3; a plurality of first pin holes 6 are provided at a position near the bottom of the side surface of the upper form protection plate 1, and a plurality of second pin holes 8 are provided at a position near the top of the side surface of the lower form protection plate 7, and the first pin holes 6 and the corresponding second pin holes 8 are connected by connecting pins; the lower part of the upper form protection plate 1 is embedded in the upper part of the lower form protection plate 7.

[0025] Due to the complex conditions in coal mines underground, the roadway heights are uneven. In case of special areas where it is necessary to temporarily add measure holes or adjust the positions of grouting holes, etc., in order to improve the applicability of the automatic hanging form device and cope with the complex conditions in coal mines underground, a form protection plate for a variable hanging form device of the present utility model is designed.

[0026] A form protection plate for a variable hanging form device of the present utility model is composed of an upper form protection plate 1 and a lower form protection plate 7. Both are installed on the existing automatic hanging form device to support the flexible form. The upper form protection plate 1 and the lower form protection plate 7 are both made of high-strength steel plates, and their lengths and widths are made according to requirements. A circle of chutes 3 is designed on the upper form protection plate 1, and sliders 4 with a length and width of 400 mm (which can also be other sizes) are movably embedded in the chutes 3. A plurality of anchor bolts are connected between the corresponding plurality of first tension anchor bolt holes 2 and the plurality of second tension anchor bolt holes 9 to further support the flexible form, and the row spacing between the first tension anchor bolt holes 2 and the second tension anchor bolt holes 9 is set according to the row spacing of the flexible form.

[0027] The working principle of a form protection plate for a variable hanging form device of the present utility model is as follows: When the conditions in coal mines underground are normal, only the upper form protection plate 1 is needed for the hanging operation of the flexible form. If it encounters a high roof area in the roadway, after the lower part of the upper form protection plate 1 is embedded in the upper part of the lower form protection plate 7, a plurality of connecting pins can be inserted into a pair of corresponding first pin holes 6 and second pin holes 8 on the upper form protection plate 1 and the lower form protection plate 7, and then the connecting pins are fixed. In this way, the upper form protection plate 1 and the lower form protection plate 7 can be fixedly connected together through the plurality of connecting pins. After being fixed, the upper form protection plate 1 and the lower form protection plate 7 are used together for the hanging operation of the flexible form. When the construction of the high roof area is completed and reaches the normal area in coal mines underground, the connecting pins can be removed one by one, and then the lower form protection plate 7 can be removed from the upper form protection plate 1, and the upper form protection plate 1 can be reused for the hanging operation of the flexible form. In case of special areas where it is necessary to add measure holes or adjust the positions of grouting holes, the position of the flexible form can be exposed by adjusting the position of the moving slider 4, and measure holes can be added on it or grouting holes at appropriate positions can be exposed, so as to realize the connection between the measure holes or grouting holes and the pipelines.

[0028] Therefore, choosing the upper protective formwork 1 or the combination of the upper protective formwork 1 and the lower protective formwork 7 and applying them together on the automatic formwork hanging device can ensure that the automatic formwork hanging device can be applicable under various conditions in the coal mine underground.
