Description

Technical Field

[0001] This utility model relates to the field of support technology, and in particular to a roadway sliding support for a roadway tunneling machine. Background Technology

[0002] A tunneling machine roadway is a roadway excavated using comprehensive mechanized tunneling technology. The support system refers to the roadway support system, which achieves efficient support through mechanized operations and maintains structural stability through physical support to ensure roadway safety.

[0003] Currently, while existing roadway supports for roadways can provide some support and ensure basic safety during mining operations, they cannot enable the assembled support frame to be quickly and easily slid into unsupported roadway sections. Installation often requires a large amount of manpower and is time-consuming, resulting in poor continuity of support operations and complicated mining procedures, which in turn affects overall mining efficiency and safety. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies, such as the time-consuming installation of permanent support and the complex procedures for roadway protection, which affect the overall mining efficiency and safety. Therefore, a roadway sliding support for a roadway is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A roadway sliding support for a roadway machine includes:

[0007] Multiple support arch beams and a roadheader cutting section, with supporting beam legs provided at both ends of the bottom of the multiple support arch beams;

[0008] The cutting section of the roadheader is equipped with a temporary support assembly, which is used to temporarily support the top of the tunnel during the headworks operation. The multiple support arch beams and the cutting section of the roadheader are equipped with a sliding traction mechanism, which is used to transport the assembled support arch beams and support beam legs.

[0009] In one possible design, the temporary support assembly includes a temporary support placed on top of the cutting section of the roadheader. Connecting frames are rotatably mounted on both front sides of the cutting section. Support rods are fixedly mounted on the rear sides of both connecting frames. The other ends of the two support rods are hinged to the bottom sides of the temporary support. Swing cylinders are hinged on both rear sides of the cutting section. The output ends of the two swing cylinders are respectively hinged to the two connecting frames. Telescopic cylinders are hinged on one side of each of the two connecting frames. The output ends of the two telescopic cylinders are respectively hinged to the bottom sides of the temporary support.

[0010] In one possible design, the sliding traction mechanism includes a slide rail fixed to the bottom of the support arch beam by a U-shaped clamp. A U-shaped frame is provided below the slide rail. Two pulleys are rotatably arranged on the inner side of the U-shaped frame. The two pulleys are rolled inside the two sides of the slide rail. An electric hoist is fixedly installed at the bottom of the U-shaped frame. A hanging frame is fixedly installed on one side of the electric hoist. A winch is fixedly installed on the top side of the cutting section of the roadheader. A steel cable is wound around the outside of the drum of the winch. A hook is fixedly installed at one end of the steel cable. The hook can be detached and hung on the hanging frame.

[0011] In one possible design, a splicing block is fixedly provided at one end of the slide rail, and a splicing groove is provided at the other end of the slide rail, allowing the splicing block to detach and be inserted into the splicing groove.

[0012] In one possible design, each of the bottom ends of the multiple support arch beams is fixedly provided with a plug-in post, and each of the multiple support beam legs is provided with a plug-in groove at its top. The plug-in post of the support arch beam can be disengaged and plugged into the plug-in groove at the top of the support beam leg. The same clamp is fixed to the outside of the plug-in joint between the support arch beam and the support beam leg by bolts.

[0013] In one possible design, two fixing pins are longitudinally fixed on one side of each of the support beam legs. The fixing pins of adjacent support beam legs that are not located on the same bracket arch are fitted with the same connecting frame, and the front end of each fixing pin can be disengaged and locked with the pin frame.

[0014] In this application, when there are workers at the tunnel head, the sway cylinder is activated first. Its output end retracts and pulls the connecting frame that is hinged to it to rotate. At this time, the support rod fixed on one side of the connecting frame and the telescopic cylinder on it also rotate. During the rotation of the support rod, the support rod will lift the temporary support upward and make it unfold at the top of the cutting part of the roadway machine. When the temporary support is close to the top wall of the tunnel, the retraction of the output end of the sway cylinder stops. At the same time, the two telescopic cylinders hinged on one side of the two support rods are activated simultaneously. The output end of the telescopic cylinder extends and pushes the bottom of the temporary support, so that the temporary support unfolds in a fan shape and changes its posture until the temporary support unfolds to a horizontal state, thus completing the temporary support for the tunnel top and ensuring the safety of the workers (the cutting part of the roadway machine is equipped with a hydraulic drive unit. One end of the hydraulic drive unit is connected to the sway cylinder and telescopic cylinder on the temporary support assembly, and the other end is connected to the hydraulic system of the roadway machine).

[0015] Next, the slide rail is fixed to the bottom of the support arch beam using U-shaped clamps. Then, the insertion pins at the bottom of the support arch beam are inserted into the insertion slots at the top of the support beam legs. Finally, the same clamp is bolted to the outside of the insertion point between the support arch beam and the support beam legs to ensure a stable connection between them, forming a separate support frame. If assembling the support frames is required, the connecting frame can be fitted onto the fixing pins of adjacent support beam legs that are not located on the same support arch beam. Then, the front end of each fixing pin is secured to the pin holder, completing the assembly of multiple support frames. When assembling, the splicing block at one end of the slide rail on each support arch beam can be inserted into the splicing groove of another slide rail to complete the assembly between the slide rails and form a whole slide rail. If only a support frame needs to be assembled, this connection step is not required. After assembling the support arch beam, install the U-shaped frame on the electric hoist and roll the two pulleys on the U-shaped frame into the slide rail so that the U-shaped frame can drive the electric hoist to slide along the slide rail. Then start the electric hoist and hook the hook frame of the electric hoist onto the assembled support arch beam and other components. Then lift the assembled components to remove them from the ground or assembly platform.

[0016] Then, the winch fixed on one side of the top of the cutting section of the roadheader is started, and the steel cable wound on the outside of the winch drum is released. The hook fixed on one end of the released steel cable is hooked onto the hanger. After hooking, the winch is started to work in reverse to wind up the steel cable. Under the traction of the steel cable, the assembled frame slides on the slide rail through pulleys until it reaches the unsupported roadway section. After reaching the unsupported roadway section, the frame is lowered, and the assembled support arch beams and support legs are installed and fixed to the roadway surface (ground or wall) to complete the permanent support work.

[0017] This utility model has the following beneficial effects:

[0018] In this invention, by setting up a temporary support component, when there are workers at the head of the tunnel, the sway cylinder is activated to drive the connecting frame to rotate, thereby raising the support rod and unfolding the temporary support at the top of the cutting section of the roadway machine. After approaching the top wall of the tunnel, the telescopic cylinder pushes the bottom of the temporary support to unfold it into a fan shape to a horizontal state, quickly completing the temporary support of the tunnel top. This process does not require manual carrying of the support pillars, reducing manpower consumption and working time, significantly improving the efficiency of temporary support, and ensuring the safety of workers.

[0019] In this invention, by setting up a sliding traction mechanism, after the support frame is assembled, a winch is used to release and wind up the steel cable. Through the connection between the hook and the hanging frame, the assembled frame is pulled along the slide rail to the unsupported roadway section. There is no need for manual handling of each frame, which reduces the large amount of manpower and time consumption during the installation of a single frame. It realizes permanent support along the goaf in one go, making the support operation more continuous and efficient, effectively simplifying the mining process, and improving the overall mining efficiency and safety.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] In one embodiment

[0027] Reference Figure 1-4 A stent, comprising:

[0028] Multiple support arch beams 1 and a roadheader cutting section 2, etc., wherein each support arch beam 1 has support legs 11 at both ends of its bottom, providing a stable support foundation for the entire support.

[0029] A temporary support assembly is installed on the cutting section 2 of the roadheader. This temporary support assembly includes a temporary bracket 16 placed on top of the cutting section 2. Connecting frames 17 are rotatably installed on both sides of the front of the cutting section 2. Support rods 19 are firmly fixed to the rear of these two connecting frames 17. The other end of the support rods 19 is hinged to the bottom sides of the temporary bracket 16. At the same time, swing cylinders 18 are hinged on both sides of the rear of the cutting section 2. The output ends of the two swing cylinders 18 are respectively hinged to the two connecting frames 17. In addition, telescopic cylinders 20 are also hinged on one side of the two connecting frames 17. The output of these two telescopic cylinders 20... The ends are also hinged to the bottom sides of the temporary support 16. When there are workers at the head of the tunnel, the swing cylinder 18 is activated, and its output end retracts, pulling the connecting frame 17 to rotate, which in turn drives the support rod 19 and the telescopic cylinder 20 to rotate. The support rod 19 lifts the temporary support 16 upward, so that it unfolds at the top of the cutting section 2 of the roadway. When the temporary support 16 is close to the top wall of the tunnel, the retraction of the swing cylinder 18 is stopped, and the two telescopic cylinders 20 are activated at the same time. Their output ends extend to push the bottom of the temporary support 16, so that the temporary support 16 unfolds in a fan shape and changes its posture until it is unfolded to a horizontal state, completing the temporary support for the top of the tunnel and providing safety for the workers.

[0030] Multiple support arch beams 1 and the cutting section 2 of the roadheader are also equipped with sliding traction mechanisms. In these mechanisms, slide rails 3 are fixed to the bottom of the support arch beams 1 by U-shaped clamps. Below the slide rails 3, a U-shaped frame 5 is installed. Two pulleys 4 are rotatably mounted on the inner side of the U-shaped frame 5. These two pulleys 4 are rolled inside the two sides of the slide rails 3, allowing the U-shaped frame 5 to move flexibly on the slide rails 3. An electric hoist 6 (model: PA200) is fixedly installed at the bottom of the U-shaped frame 5. A hanging bracket 7 is fixedly installed on one side of the electric hoist 6. A winch is fixedly installed on one side of the top of the cutting section 2 of the roadheader. 8. A steel cable 9 is wound around the outside of the drum of the winch 8. A hook 10 is fixedly installed at one end of the steel cable 9. The hook 10 can be detached and hooked onto the hanger 7. When it is necessary to transport the assembled support arch beam 1 and support beam leg 11, the assembled parts are first hooked by the electric hoist 6, and then the winch 8 (KCD-0.5-2) is started to release the steel cable 9. The hook 10 is hooked onto the hanger 7, and then the winch 8 is started to work in reverse to wind up the steel cable 9. Under the traction of the steel cable 9, the assembled frame slides on the slide rail 3 through the pulley 4 until it slides to the unsupported roadway section.

[0031] To facilitate the installation and assembly of the slide rail 3, a splicing block 301 is fixedly provided at one end of the slide rail 3, and a splicing groove 302 is provided at the other end. The splicing block 301 can be detachably inserted into the splicing groove 302. During installation, one slide rail 3 is inserted into the splicing groove 302 of another slide rail 3 through the splicing block 301, thereby completing the assembly between the slide rails 3 and forming an integral slide rail 3, providing a stable track for the sliding of the frame.

[0032] Regarding the connection between the support arch beam 1 and the supporting beam leg 11, each of the bottom ends of the multiple support arch beams 1 is fixedly provided with a plug-in post 101, and each of the multiple supporting beam legs 11 is provided with a plug-in groove at its top. The plug-in post 101 of the support arch beam 1 can be detachably inserted into the plug-in groove at the top of the supporting beam leg 11. At the same time, on the outside of the plug-in point between the support arch beam 1 and the supporting beam leg 11, the same clamp 12 is fixedly provided by bolts, which further enhances the stability of the connection.

[0033] This application can be used in the field of tunnel boring machine sliding support installation technology, and can also be used in other fields applicable to this application.

[0034] In another embodiment

[0035] Reference Figure 2 and Figure 4 A sliding support for roadway tunneling machines is described. This invention relates to the field of sliding support installation technology for roadway tunneling machines. If multiple support frames need to be assembled, two fixing pins 13 are longitudinally fixed on one side of each support beam leg 11. The fixing pins 13 of adjacent support beam legs 11 that are not located on the same support arch beam 1 are fitted with the same connecting frame 14. The front end of each fixing pin 13 can be detached from the ground and fitted with a pin frame 15. The connecting frame 14 is fitted onto the fixing pin 13, and then the pin frame 15 is fitted on, thus completing the assembly of multiple support frames and meeting the support requirements of different roadway lengths.

[0036] However, as is well known to those skilled in the art, the working principles and wiring methods of the electric hoist 6, winch 8, swing cylinder 18 and telescopic cylinder 20 are all conventional means or common knowledge, and will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0037] The accompanying drawings in this application are for illustrative purposes only.
