Description

Technical Field

[0001] This utility model relates to the field of temporary support technology, specifically to a temporary support system for an integrated tunneling and anchoring machine. Background Technology

[0002] like Figure 1 As shown, current temporary supports for roadheader-anchor integrated machines mostly adopt a dual-cylinder, long-span simply supported beam structure, and the main structure of the temporary support is curved. During the excavation operation, the long span of the temporary support prevents it from conforming to the working face above the coal roadway, thus failing to obtain sufficient frictional reaction force to suppress the machine's retraction. Simultaneously, the curved shape of the temporary support easily generates significant flexural deformation when bearing the retraction force. The supporting effect of the front cylinder only applies the supporting force to the working face below the coal roadway, failing to suppress the front section of the machine from tilting up. This hinders the simultaneous roadheader-anchor operation and affects coal production efficiency. Utility Model Content

[0003] To address the shortcomings of existing technologies, a temporary support system for an integrated tunneling and anchoring machine is proposed. This system solves the problem in the background technology that temporary support systems with dual hydraulic cylinders and long spans of simply supported beams cannot prevent the front section of the machine from tilting up and cannot effectively achieve simultaneous tunneling and anchoring operations.

[0004] To achieve the above objectives, the present invention proposes the following technologies: A temporary support for a tunneling and anchoring machine includes an auxiliary support mechanism mounted on the machine. The auxiliary support mechanism includes a secondary support component, which is hinged to a front support mounted on the front side of the machine via a connecting arm, allowing the secondary support component to be deployed for auxiliary support by rotation.

[0005] Furthermore, the auxiliary support mechanism also includes an auxiliary hydraulic cylinder disposed below the secondary support assembly. The bottom end of the auxiliary hydraulic cylinder is hinged to the integrated machine. The extension and retraction of the auxiliary hydraulic cylinder drives the secondary support assembly to rotate around the front support.

[0006] Furthermore, the front support includes a front support assembly hinged to the connecting arm, and a support body mounted above the integrated machine. The secondary support assembly is located above the support body to facilitate contact with the upper working surface for auxiliary support.

[0007] Furthermore, the front support also includes a front support cylinder disposed below the front support assembly, the bottom end of the front support cylinder being hinged to the support leg, the support leg being disposed at the front end of the integrated machine and abutting against the lower working surface.

[0008] Furthermore, it also includes a support guide rod, the upper and lower ends of which are hinged to the support body and the integrated machine, respectively. The auxiliary hydraulic cylinder is located between the front support hydraulic cylinder and the support guide rod, and the length of the support guide rod is adjustable.

[0009] Furthermore, the auxiliary support assembly includes a floating support portion connected to the connecting arm. The floating support portion is provided in two sets, and the two sets of floating support portions are connected by a central connecting plate. The floating support portion is hinged to the output end of the auxiliary cylinder.

[0010] Furthermore, the floating support part includes fixed support plates fixedly connected to both sides below the central connecting plate, and a floating support plate is movably connected above the fixed support plates via a support ball head.

[0011] Furthermore, the fixed support plate is also provided with two sets of elastic reset structures. The two sets of elastic reset structures are symmetrically arranged on opposite sides of the support ball head and are respectively connected to the floating support plate. Both sets of elastic reset structures are used to apply elastic force to the floating support plate in the direction of approaching or away from the fixed support plate.

[0012] Furthermore, on both sides of the support ball head, there are angle floating limit plates for limiting the movement angle of the floating support plate and position floating limit plates for limiting the movement position of the floating support plate.

[0013] Compared with the prior art, the comprehensive effects brought about by this utility model include: This application sets up an auxiliary support mechanism, which is hinged to the front support structure by rotating the connecting arm to drive the auxiliary support component to perform support. In conjunction with the front support, it improves the support effect. Since the auxiliary support mechanism is set on the integrated machine, the whole is fulcrumd on the integrated machine, so the support force can be distributed on the machine body, thereby suppressing the machine body from tilting, providing greater downward pressure and friction to the machine body, and ensuring the stability of the machine body.

[0016] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] In this document, terms such as “up,” “down,” “left,” “right,” and “top” indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0018] like Figures 1 to 11 As shown, a temporary support for an integrated excavator and anchor machine includes an auxiliary support mechanism installed on the integrated machine 1. The auxiliary support mechanism includes a secondary support component 2, which is hinged to a front support installed on the front side of the integrated machine 1 via a connecting arm 3, so that the secondary support component 2 can be deployed for auxiliary support by rotation.

[0019] By setting up an auxiliary support mechanism, the auxiliary support component 2 is hinged to the front support structure. The rotating connecting arm 3 drives the auxiliary support component 2 to perform support. In conjunction with the front support, the support effect is improved. Since the auxiliary support mechanism is set on the integrated machine 1, the whole is centered on the integrated machine 1, so the support force can be distributed on the machine body, thereby suppressing the machine body from tilting up, providing greater downward pressure and friction to the machine body, and ensuring the stability of the machine body.

[0020] In the temporary support of the tunneling and anchoring machine in this embodiment, the front support includes a front support component 5 hinged to the connecting arm 3, and a support body 6 erected above the integrated machine 1. The auxiliary support component 2 is located above the support body 6 so as to abut against the upper working face 7 to achieve auxiliary support.

[0021] With the above setup, the front support component 5 serves as the main support structure to support and protect the upper working surface 7 in front of the integrated machine 1, and the support body 6 is connected between the front support component 5 and the bracket at the rear of the integrated machine 1 to shield and protect the body of the integrated machine 1.

[0022] Specifically, the support body 6 includes a dust collection device installed on the front side of the frame and a material storage structure installed above the rear of the frame. The above-mentioned structures and the specific settings of the front support component 5 in this application can adopt the existing settings in the prior art, and will not be described in detail here.

[0023] In the temporary support of the tunneling and anchoring machine in this embodiment, the front support also includes a front support cylinder 8 located below the front support assembly 5. The bottom end of the front support cylinder 8 is hinged to the support leg 9, and the support leg 9 is located at the front end of the integrated machine 1 and abuts against the lower working surface.

[0024] The front support cylinders 8 are located on both sides of the integrated machine 1, with their bottoms connected to the lower working surface, ensuring sufficient support force to support the front support assembly 5 and providing good support for the working surface of the integrated machine 1 during its forward operation.

[0025] In the temporary support of the tunneling and anchoring machine in this embodiment, the auxiliary support mechanism also includes an auxiliary hydraulic cylinder 4 located below the secondary support assembly 2. The bottom end of the auxiliary hydraulic cylinder 4 is hinged to the integrated machine 1. The extension and retraction of the auxiliary hydraulic cylinder 4 drives the secondary support assembly 2 to rotate around the front support.

[0026] Two auxiliary hydraulic cylinders 4 are symmetrically arranged on the left and right sides of the front end of the integrated machine 1. The auxiliary hydraulic cylinders 4 are directly installed on the integrated machine 1. The auxiliary hydraulic cylinders 4 drive the secondary support component 2 to unfold and support or retract. When supporting, the supporting force acts in the opposite direction on the front end of the integrated machine 1, which can suppress the machine body from tilting.

[0027] With the above configuration, the temporary support adopts a continuous beam support structure with four hydraulic cylinders in the front and middle sections, which improves the rigidity and stability of the temporary support. When the temporary support is in place, the flat design of the head and tail of the temporary support can transfer the frictional force with the upper working face 7 to the machine body, reducing the machine body's backlash. At the same time, the retraction of the auxiliary hydraulic cylinder 4 allows the secondary support structure to fold onto the main structure, ensuring that the tunneling and anchoring machine 1 maintains the lowest possible height when moving forward, achieving good maneuverability.

[0028] Specifically, the temporary support adopts hydraulic control action logic. The starting pressure of different cylinders is set through the valve body. When the support action is performed, the front support acts as the main support, and the support cylinder 8 is activated first until the upper plane of the main support touches the upper working surface 7. Then the auxiliary support mechanism is activated until the jacking is completed. After the support operation is completed, the auxiliary cylinder 4 of the auxiliary support structure will be depressurized first and folded on the main support. Then the main support support cylinder 8 is activated until the temporary support is retracted.

[0029] In the temporary support of the tunneling and anchoring machine in this embodiment, a support guide rod 10 is also included. The upper and lower ends of the support guide rod 10 are respectively hinged to the support body 6 and the integrated machine 1. The auxiliary oil cylinder 4 is located between the front support oil cylinder 8 and the support guide rod 10. The length of the support guide rod 10 is adjustable.

[0030] Specifically, the support guide rod 10 includes two telescopic rods. The first rod is inserted into the second rod. The second rod has positioning holes. The length can be adjusted and fixed by inserting positioning pins into positioning holes at different positions. This facilitates the adjustment of the height of the support body 6 located above it and makes it easier to clean or repair the support body 6.

[0031] In the temporary support of the tunneling and anchoring machine in this embodiment, the auxiliary support component 2 includes a floating support part 11 connected to the connecting arm 3. The floating support part 11 is provided in two sets, and the two sets of floating support parts 11 are connected by a middle connecting plate 12. The floating support part 11 is hinged to the output end of the auxiliary oil cylinder 4.

[0032] By setting up the floating support part 11, it can better adapt to the surface conditions of the upper working surface 7. The angle and orientation of the contact surface between the secondary support component 2 and the upper working surface 7 can be finely adjusted through floating, so that the secondary support component 2 fits better with the upper working surface 7, thereby improving the supporting effect. Furthermore, the floating support part 11 is hinged to the auxiliary oil cylinder 4, so that the floating support part 11 can rotate to adapt to the upper working surface 7 with an angle, ensuring the supporting effect.

[0033] In the temporary support of the tunneling and anchoring machine in this embodiment, the floating support part 11 includes fixed support plates 13 fixedly connected to both sides below the middle connecting plate 12, and a floating support plate 15 is movably connected above the fixed support plate 13 through a support ball head 14.

[0034] Specifically, the fixed support plate 13 and the floating support plate 15 are stacked and spaced apart. One of the fixed support plate 13 and the floating support plate 15 is provided with a ball-and-socket structure, and the other is provided with a support ball head 14 embedded in the ball-and-socket structure for rotation relative to the ball-and-socket structure. The floating support plate 15 is used to abut against the roof of the roadway, and the support angle is adaptively adjusted through the cooperation of the support ball head 14 and the ball-and-socket structure. That is, the support ball head 14 can rotate omnidirectionally relative to the ball-and-socket structure. Through the cooperation of the support ball head 14 and the ball-and-socket structure, the floating support plate 15 can adapt to the roadway roof with different inclination states, ensuring that the floating support plate 15 is in a state of close contact with the roadway roof, further improving the supporting effect.

[0035] A hinge seat 19 is provided below the fixed support plate 13 for connection with the auxiliary oil cylinder 4.

[0036] In the temporary support of the tunneling and anchoring machine in this embodiment, the fixed support plate 13 is also provided with two sets of elastic reset structures 16. The two sets of elastic reset structures 16 are symmetrically arranged on opposite sides of the support ball head 14 and are respectively connected to the floating support plate 15. Both sets of elastic reset structures 16 are used to apply elastic force to the floating support plate 15 in the direction of approaching or away from the fixed support plate 13.

[0037] When both sets of elastic reset structures 16 are used to apply an elastic force to the floating support plate 15 in the direction close to the fixed support plate 13, the two sets of elastic reset structures 16 can jointly pull the floating support plate 15 to the fixed support plate 13, achieving elastic fixation of the floating support plate 15. This allows the floating support plate 15 to be reset by the cooperation of the two sets of elastic reset structures 16 when it is pulled away from the roadway roof by the reverse force. Similarly, when both sets of elastic reset structures 16 are used to apply an elastic force to the floating support plate 15 in the direction away from the fixed support plate 13, the two sets of elastic reset structures 16 can jointly support the floating support plate 15 on the fixed support plate 13, achieving elastic support fixation of the floating support plate 15. This allows the floating support plate 15 to be reset by the cooperation of the two sets of elastic reset structures 16 when it is pulled away from the roadway roof by the reverse force.

[0038] Specifically, the specific configuration of the elastic reset structure 16 can be referred to the structure in the prior art, and will not be described in detail here.

[0039] In the temporary support of the tunneling and anchoring machine in this embodiment, the two sides of the support ball head 14 are respectively provided with an angle floating limit plate 17 for limiting the movement angle of the floating support plate 15, and a position floating limit plate 18 for limiting the movement position of the floating support plate 15.

[0040] Matching the angle floating limit plate 17, a fulcrum plate 20 is provided on the fixed support plate 13. The top of the fulcrum plate 20 is conical. The angle floating limit plate 17 is located on the floating support plate 15. When the floating support plate 15 rotates through the support ball head 14, the angle floating limit plate 17 abuts against the inclined surface of the fulcrum plate 20 to limit the rotation angle, thereby preventing the floating support plate 15 from rotating too much. The position floating limit plate 18 is located at the end of the floating support plate 15. The corresponding fixed support plate 13 has limit grooves on both sides of its end. The position floating limit plate 18 extends into the limit groove, thereby preventing the floating support plate 15 from displacing too much along its length, causing the support contact surface to shift.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Unless otherwise explicitly limited, those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
