[0001] This utility model relates to the field of anchor drilling equipment technology, specifically to a folding anchor drilling rig pedal device and an anchor drilling rig. Background Technology

[0002] In the current promotion of anchor bolt drilling rig technology, narrow anchor bolt drilling rigs are becoming increasingly popular due to their narrow overall body, maneuverability, and strong adaptability to roadways. However, the narrow body of narrow anchor bolt drilling rigs limits the space for personnel operating platforms, and operational comfort and safety have always been among the main drawbacks of their support operations. Installing a large platform on a narrow drilling rig would increase the overall width of the rig, reduce its flexibility, and potentially affect its movement. The application of folding platforms is feasible to solve the problem of insufficient platform assembly space. However, folding platforms require the removal of guardrails when folding, and narrow drilling rigs cannot provide storage space for the removed guardrails, making it difficult to apply folding platforms to narrow drilling rigs. Summary of the Invention

[0003] The technical problem this utility model aims to solve is to address the shortcomings and deficiencies of existing technologies by proposing a folding anchor bolt drilling rig pedal device. This folding anchor bolt drilling rig pedal device allows the movable pedal to be opened as needed to expand the support operation space of the pedal platform, meeting the operational needs of workers. During non-operational periods, the movable pedal can be folded away to reduce the overall width of the pedal platform, thus matching the travel requirements of narrow anchor bolt drilling rigs. Furthermore, when folded, the movable section of the guardrail can be disassembled and mounted on the middle fixed section, eliminating the need for a dedicated storage space on the drilling rig, further solving the problem of limited assembly space for folding pedals.

[0004] The folding anchor drill rig pedal device of this utility model embodiment is characterized by comprising a pedal body and guardrails.

Detailed Implementation

[0024] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0025] like Figures 1-6As shown, the folding anchor drilling rig pedal device of this utility model embodiment includes a pedal body and a guardrail. The guardrail surrounds the outer periphery of the pedal body and includes a front guardrail, a rear guardrail, a left side rail 4, and a right side rail 5. The pedal body includes a fixed pedal 1 and movable pedals movably connected to both sides of the fixed pedal 1. The left side rail 4 and the right side rail 5 are respectively installed at opposite ends of the two movable pedals. The front guardrail and the rear guardrail are respectively installed on both sides in the width direction of the pedal body. Both the front guardrail and the rear guardrail include a middle fixed section and two movable sections on both sides. The middle fixed section is connected to the fixed pedal 1. The two movable sections are detachably connected between the left side rail 4 and the middle fixed section and between the right side rail 5 and the middle fixed section, respectively. The middle fixed section is provided with a hook point for attaching the movable section after it has been disassembled.

[0026] Understandably, when the bolting rig needs to move forward in the roadway, the movable section can be detached from the middle fixed section and the side rails. Then, the movable pedal can be folded to reduce the overall width of the pedal to match the travel requirements of the narrow bolting rig. The detached movable section can be attached to the middle fixed section through the attachment point, eliminating the need for a dedicated storage space on the bolting rig. This solves the problem of limited assembly space for folding pedals and enables their application on narrow rigs. When the bolting rig reaches the work area, the movable pedal can be opened to form a large platform with the fixed pedal 1, solving the problem of limited operating platform space for personnel on existing narrow bolting rigs. At the same time, the movable section can be reinstalled to form a guardrail protecting the entire perimeter of the pedal.

[0027] The folding anchor drill rig pedal device of this utility model embodiment has guardrails surrounding the outer periphery of the pedal body and including a front guardrail, a rear guardrail, a left side rail 4, and a right side rail 5. The pedal body includes a fixed pedal 1 and movable pedals movably connected to both sides of the fixed pedal 1. The left side rail 4 and the right side rail 5 are respectively installed at opposite ends of the two movable pedals. The front guardrail and the rear guardrail are respectively installed on both sides in the width direction of the pedal body, and both the front guardrail and the rear guardrail include a middle fixed section and two movable sections on both sides. The middle fixed section is connected to the fixed pedal 1, and the two movable sections are detachably connected to the left side rail 4. Between the middle fixed section and the right side rail 5, and between the middle fixed section, there are attachment points on the middle fixed section for attaching the disassembled movable section. Thus, the movable pedal can be opened as needed to expand the support operation space of the pedal platform and meet the operation needs of the operators. During non-operation periods, the movable pedal can be folded up to reduce the overall width of the pedal platform, thereby matching the travel requirements of the narrow anchor drilling rig. When folded, the movable section of the guardrail can be disassembled and attached to the middle fixed section, eliminating the need for a dedicated storage space on the drilling rig, further solving the problem of limited assembly space for the folding pedal.

[0028] In some embodiments, such as Figure 1 and Figure 3 As shown, a first sleeve 6 is provided on the side of the middle fixed section facing the left side rail 4, and a second sleeve 7 is provided on the left side rail 4 opposite to the first sleeve 6. A first fixing pin 16 and a second fixing pin 16 are provided on the movable section between the left side rail 4 and the middle fixed section, which correspond to and cooperate with the first sleeve 6 and the second sleeve 7. That is to say, the middle fixed section, the left side rail 4 and the movable section between them are detachably connected by the assembly of sleeves and pins, which is simple in structure and easy to assemble and disassemble.

[0029] Furthermore, a third sleeve 8 is provided on the side of the middle fixed section facing the right side rail 5, and a fourth sleeve 9 is provided on the right side rail 5 opposite to the third sleeve 8. A third fixed pin 16 and a fourth fixed pin 16 are provided on the movable section between the right side rail 5 and the middle fixed section, which are corresponding to and cooperate with the third sleeve 8 and the fourth sleeve 9.

[0030] In other words, pins are set on both sides of the movable section, and sleeves are set on the middle fixed section and the two side rails. The movable section is detachably connected between the middle fixed section, the left side rail 4 and the right side rail 5 by assembling the pins and sleeves. The assembly method is simple and the disassembly and assembly are convenient.

[0031] Specifically, such as Figure 4 As shown, a second sleeve 7 is provided on the front and rear sides of the left side rail 4. The middle fixed section includes a front middle fixed section 10 and a rear middle fixed section 11. A first sleeve 6 is provided on the side of the front middle fixed section 10 facing the left side rail 4 and the side of the rear middle fixed section 11 facing the left side rail 4. A fourth sleeve 9 is provided on the front and rear sides of the right side rail 5. A third sleeve 8 is provided on the side of the front middle fixed section 10 facing the right side rail 5 and the side of the rear middle fixed section 11 facing the right side rail 5. Thus, two movable sections with front-to-back spacing can be installed between the two second sleeves 7 and the two corresponding first sleeves 6. The two movable sections, together with the left side rail 4, can form a guardrail structure around the movable pedal on the left. Similarly, two movable sections with front-to-back spacing can be installed between the two fourth sleeves 9 and the two corresponding third sleeves 8. The two movable sections, together with the right side rail 5, can form a guardrail structure around the movable pedal on the right.

[0032] In some embodiments, the attachment point is a mounting sleeve that can be adapted to the fixed pin 16 of the movable section. Thus, after the movable section is disassembled, the movable section can be directly mounted on the intermediate fixed section by utilizing the cooperation between the fixed pin 16 and the mounting sleeve, without the need to set up other structures for mounting on the movable section. This realizes the multi-functional utilization of the fixed pin 16 and simplifies the disassembly and assembly process and manufacturing process.

[0033] In some embodiments, such as Figure 4As shown, the mounting sleeve includes at least one set of spaced-apart first mounting sleeves 14 and one set of spaced-apart second mounting sleeves 15. The spacing of the first mounting sleeves 14 matches the length of the first movable section 12, and the spacing of the second mounting sleeves 15 matches the length of the second movable section 13. The first movable section 12 is located between the left side rail 4 and the middle fixed section, and the second movable section 13 is located between the right side rail 5 and the middle fixed section. That is, the middle fixed section includes at least two sets of mounting sleeves. One set of mounting sleeves is formed by the spaced-apart first mounting sleeves 14, and the other set of mounting sleeves is formed by the spaced-apart second mounting sleeves 15. The two sets of mounting sleeves correspond to the movable sections that have been removed from both sides.

[0034] In some embodiments, the first mounting sleeve 14 and the second mounting sleeve 15 are located on different sides of the front intermediate fixed section 10; and / or, the first mounting sleeve 14 and the second mounting sleeve 15 are located on different sides of the rear intermediate fixed section 11. In other words, the first movable section 12 and the second movable section 13 are mounted on different sides of the intermediate fixed section, thereby avoiding assembly interference.

[0035] Specifically, such as Figure 5 As shown, a set of spaced-apart mounting cylinders are provided on both sides of the front middle fixed section 10 and both sides of the rear middle fixed section 11. The four sets of mounting cylinders are respectively attached to the two movable sections on the left and the two movable sections on the right.

[0036] Furthermore, such as Figure 1 As shown, the rear middle fixed section 11 includes a left guardrail and a right guardrail spaced apart along the length of the pedal body. The portion of the pedal body located between the left and right guardrails is used to assemble the ladder 17. That is, the rear middle fixed section 11 has a gap in the middle to facilitate the installation of the ladder 17 and allow operators to easily access the pedal.

[0037] Furthermore, such as Figure 1 and Figure 5 As shown, the left and right guardrails are equipped with corresponding sleeves, and the left guardrail has a first sleeve 6 on the side facing the left side rail, and the right guardrail has a third sleeve 8 on the side facing the right side rail. That is, when the movable pedal is folded, the movable section can be hung across the left and right guardrails.

[0038] In some embodiments, the movable pedal includes a first pedal 2 and a second pedal 3, the first pedal 2 and the second pedal 3 being respectively connected to both sides of the fixed pedal 1 along its length. For example... Figure 1The outer periphery of the first pedal 2 and the outer periphery of the second pedal 3 are respectively connected to movable guardrails. Combined with the second front side rail and the second rear side rail of the fixed pedal 1, they can form an overall guardrail around the outer periphery of the pedal body. When the large platform is needed for operation, both the first pedal 2 and the second pedal 3 are opened. When the large platform is not needed for operation, the movable guardrails on the first pedal 2 and the second pedal 3 can be removed, and then the first pedal 2 and the second pedal 3 can be folded to a state perpendicular to the fixed pedal 1. At this time, the width of the entire pedal platform is only the width of the fixed pedal 1, which facilitates the movement of the narrow anchor drilling vehicle.

[0039] Furthermore, the fixed pedal 1 is provided with a connecting ear plate 18, and the movable pedal is provided with a connecting protrusion that is movably connected to the connecting ear plate.

[0040] In some embodiments, the upper surfaces of the fixed pedal 1 and the movable pedal are respectively provided with a first sliding track and a second sliding track. When the movable pedal is opened to be flush with the fixed pedal 1, the first sliding track and the second sliding track are opposite each other. Thus, in the open state, the first sliding track and the second sliding track can form a complete track, facilitating the movement of the single drilling rig.

[0041] The anchor drilling rig of this utility model embodiment includes the folding anchor drilling rig pedal device of the above embodiment.

[0042] The anchor drilling rig of this utility model adopts the above-mentioned folding anchor drilling rig pedal device. The guardrail surrounds the outer periphery of the pedal body and includes a front guardrail, a rear guardrail, a left side rail 4, and a right side rail 5. The pedal body includes a fixed pedal 1 and movable pedals movably connected to both sides of the fixed pedal 1. The left side rail 4 and the right side rail 5 are respectively installed at opposite ends of the two movable pedals. The front guardrail and the rear guardrail are respectively installed on both sides in the width direction of the pedal body. Both the front guardrail and the rear guardrail include a middle fixed section and two movable sections on both sides. The middle fixed section is connected to the fixed pedal 1, and the two movable sections are detachably connected. Between the left side rail 4 and the middle fixed section, and between the right side rail 5 and the middle fixed section, there are attachment points on the middle fixed section. These attachment points are used to attach the disassembled movable section. Thus, the movable pedal can be opened as needed to expand the support operation space of the pedal platform and meet the operation needs of the workers. During non-operation periods, the movable pedal can be folded up to reduce the overall width of the pedal platform, thereby matching the travel requirements of the narrow anchor drilling rig. When folded, the movable section of the guardrail can be disassembled and attached to the middle fixed section, eliminating the need for a dedicated storage space on the drilling rig, further solving the problem of limited assembly space for folding pedals.
