Description

Technical Field

[0001] This utility model belongs to the field of drilling rig frame technology, specifically relating to an adjustable drilling rig support arm and a drilling rig frame having the support arm. Background Technology

[0002] During drilling operations in coal mine roadways, the support arm is a key component ensuring the stability and working range of the drilling rig. It primarily supports, positions, and adjusts the posture of the drilling rig body through the extension and retraction of the support cylinders. Currently, the connection between the support cylinders and the support frame in existing drilling rig support arms is mostly a fixed hinge or a single-position connection, resulting in a limited adjustment range for the support cylinders and making it difficult to adapt to the support stability requirements of different operating scenarios. Utility Model Content

[0003] This invention aims to solve the problem of limited adjustment range of the support arm on the drilling rig frame.

[0004] This utility model provides the following technical solution: an adjustable support arm for a drilling rig, including a connecting frame and a support cylinder; the connection between the cylinder of the support cylinder and the connecting frame includes a sliding pair and support nodes spaced apart along the sliding direction; the sliding pair is used for guidance, and the support nodes are used to provide rigid support.

[0005] Furthermore, the connecting frame has a straight long groove, the cylinder of the supporting cylinder is embedded in the straight long groove, a slider is fixed on the cylinder body, and a guide groove is opened on the groove wall of the straight long groove. The slider and the guide groove slide together to form a sliding pair. The connecting frame has pin holes distributed at intervals along the direction of the guide groove. The lug at the tail of the cylinder can be optionally aligned with the pin holes and then inserted into the pin shaft to form a support node.

[0006] Furthermore, the connecting frame includes a base plate and two side plates, which are vertically fixed to the base plate to form a straight long groove; guide grooves and pin holes are located on the two side plates.

[0007] Furthermore, two guide blocks are fixed on the cylinder of the supporting cylinder, each of the two guide blocks facing a side plate. The guide blocks have guide planes that slide and fit with the side plates, and the slider is fixed on the guide plane of the guide blocks.

[0008] Furthermore, two horizontally spaced sliders are fixed on the guide block, and two guide grooves are opened on the side plate.

[0009] A drilling rig frame includes an adjustable drilling rig support arm. The support arm is connected to the drilling rig frame via a connecting frame. The support arm is vertically installed at the four corners of the drilling rig frame and supports the tunnel roof.

[0010] Furthermore, crossbars are connected between the connecting frames of the support arms, and longitudinal bars are connected between the crossbars.

[0011] Compared with the prior art, the advantages of this utility model are:

[0012] This invention provides an adjustable support arm for drilling rigs. The cylinder of the support cylinder and the connecting frame are fitted with a sliding pair, along with support nodes spaced apart along the sliding direction, breaking the limitations of traditional fixed support arms. Taking the cooperation of a straight long groove, slider, and guide groove as an example, the cylinder can slide smoothly along the guide groove. Combined with the spaced pin holes on the connecting frame, different support nodes can be selected according to actual needs, achieving rigid support through pin fixing. This design greatly expands the adjustment range of the support arm's support position, better adapting to the support needs of different roadway roofs. Whether it's a change in roof height or local unevenness, it can be precisely adjusted to a suitable support point.

[0013] Because the support arms are flexibly adjustable and are vertically mounted at the four corners of the drilling rig frame, bracing against the tunnel roof, the drilling rig frame can remain horizontal and stable by adjusting the positions of the four support arms individually when there are differences in the height and shape of the tunnel roof. This ensures that the drilling rig can operate normally in complex tunnel environments. This improved adaptability expands the drilling rig's application range, eliminating the need for custom-designed frames or support structures for different tunnel environments and reducing equipment operating costs.

[0018] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0019] Example 1

[0020] like Figure 1 , Figure 2 As shown: A drilling rig support arm with adjustable support position includes a connecting frame 1 and a support cylinder 2; the connection between the cylinder of the support cylinder 2 and the connecting frame 1 includes a sliding pair and support nodes spaced apart along the sliding direction; the sliding pair is used for guidance, and the support nodes are used to provide rigid support.

[0021] The connecting frame 1 has a long straight groove. The cylinder of the supporting cylinder 2 is embedded in the long straight groove, and a slider 3 is fixed on the cylinder body. A guide groove 1.1 is opened on the groove wall of the long straight groove. The slider 3 and the guide groove 1.1 slide together to form a sliding pair. Pin holes 1.2 are distributed at intervals along the direction of the guide groove 1.1 on the connecting frame 1. The lug at the tail of the cylinder can be optionally aligned with the pin holes 1.2 and then inserted into the pin shaft 4 to form a support node. Through the multiple spaced pin holes 1.2, the support height of the support arm can be adjusted in stages to adapt to changes in the height of the top plate.

[0022] The connecting frame 1 includes a base plate 1.3 and two side plates 1.4. The two side plates 1.4 are vertically fixed on the base plate 1.3 to form a straight long groove. The guide groove 1.1 and the pin hole 1.2 are located on the two side plates 1.4. The base plate 1.3 and the two side plates 1.4 are welded together.

[0023] Two guide blocks 5 are fixed on the cylinder of the supporting cylinder 2, each facing a side plate 1.4. Each guide block 5 has a guide plane that slides smoothly against the side plate 1.4. A slider 3 is fixed to the guide plane of the guide block 5. The cylinder of the supporting cylinder 2 slides freely along a straight long groove under the guidance of the sliding pair (slider 3 and guide groove 1.1). The guide plane of the guide block 5 is tightly fitted with the side plate 1.4, ensuring smooth and unbiased sliding.

[0024] Two horizontally spaced sliders 3 are set on each guide block 5, which, together with the two guide grooves 1.1 on the side plate 1.4, form a four-point sliding constraint, effectively resisting the lateral force when the oil cylinder is working and preventing the cylinder from shaking.

[0025] Example 2

[0026] like Figure 3 As shown: A drilling rig frame includes an adjustable drilling support arm as described in Embodiment 1. The support arm is connected to the drilling rig frame 6 via a connecting frame 1. The support arm is vertically installed at the four corners of the drilling rig frame 6 and supports the tunnel roof.

[0027] The connecting frames 1 of the support arms are connected by crossbars 7, and the crossbars 7 are connected by longitudinal bars 8, forming a complete frame structure that connects the various support arms into a whole. This design not only enhances the robustness of the connection between the individual support arm and the frame, but also, through the synergistic effect of the crossbars 7 and longitudinal bars 8, distributes the load borne by the support arms, improving the deformation resistance and structural stability of the entire frame, and providing a solid foundation for the safe and efficient operation of the drilling rig.

[0028] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
