Detailed Implementation

[0010] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0011] Example like Figure 1 , Figure 2 As shown, Figure 1 The diagram shown is an overall schematic of the embodiment without the protective components installed; Figure 2 The diagram shown is an overall schematic of the protective components installed in the embodiment. This device includes: The tunneling assembly and the protection assembly include a frame 10 and a transmission assembly 11 mounted on the frame 10, the transmission assembly 11 including a drive module 13.

[0012] Specifically, the transmission assembly 11 is a transmission structure in the prior art that combines a worm gear reducer with a chain, used to realize the vertical lifting of the tunneling part of the tunneling assembly. The drive module 13 refers to the worm gear reducer. The drive module 13 serves as the power input and deceleration execution unit of the transmission assembly 11. Through manual operation and chain transmission, the power is transmitted to the tunneling part, thereby realizing its lifting movement.

[0013] The protective components effectively cover and protect the transmission components 11, preventing dust, gravel, rainwater, etc. from entering the transmission system during construction, while also preventing accidental contact and ensuring the safety of operators.

[0014] like Figure 2 , Figure 4 , Figure 5 , Figure 6 As shown, Figure 2 The diagram shown is an overall schematic of the protective components installed in the embodiment. Figure 4 What is shown is Figure 2 Enlarged schematic diagram of the structure at point A in the diagram; Figure 5 The diagram shown is a top view of the structure where the protective cover and the frame work together. Figure 6 What is shown is Figure 5 Enlarged schematic diagram of the structure at point B in the diagram.

[0015] The protective components are detachably mounted on the tunneling components.

[0016] The detachable protective components provide a convenient access for daily inspection, lubrication, chain tensioning, worm gear maintenance, or component replacement of the transmission assembly 11, significantly improving the maintainability of the equipment.

[0017] The protective components include: Protective cover 21, the protective cover 21 is a cover structure with an opening on one side; Connecting frame 23 is rotatably mounted on frame 10. The protective cover 21 is provided with a first connection hole 24, and the connecting frame 23 is provided with a second connection hole 25. When the protective cover 21 is covered by the transmission component 11, the connecting frame 23 is rotated to align the first connection hole 24 with the second connection hole 25 and install the pin 26. The pin 26 is threadedly engaged with the first connection hole 24. The pin 26 is screwed in to lock the protective cover 21 and the frame 10.

[0018] Specifically, the connecting frame 23 has an L-shaped structure and is rotatably mounted on the front and rear side walls of the frame 10. At least two sets are provided on each side. The end of the connecting frame 23 closest to the frame 10 is rotatably engaged with the frame 10 through a rotating shaft 231.

[0019] During installation, the protective cover 21 is placed over the outside of the transmission assembly 11, and then... Figure 4 Rotate the connecting bracket 23 in the direction of the arrow to move its L-shaped arm, clamp the side of the protective cover 21 with the corresponding part of the frame 10, and align the connecting hole 24 on the protective cover 21 with the connecting hole 25 on the connecting bracket 23. Insert the pin 26. Since the pin 26 and the connecting hole 24 are threaded, axial locking can be achieved after screwing in the pin 26, thereby firmly fixing the protective cover 21 to the frame 10 and preventing it from loosening due to vibration or external force.

[0020] like Figure 1 , Figure 2 , Figure 3 As shown, Figure 1 The diagram shown is an overall schematic of the embodiment without the protective components installed; Figure 2 The diagram shown is an overall schematic of the protective components installed in the embodiment. Figure 3 The diagram shown is a side view of the fixing block and the insert plate in an embodiment.

[0021] A fixing block 22 is provided at the bottom of the protective cover 21. A slot is provided through the fixing block 22. A plug plate 12 is provided at the lower end of the frame 10 corresponding to the slot. The plug plate 12 matches the shape of the slot and the two are plugged in. At least two sets of fixing blocks 22 and plug plates 12 are provided at corresponding positions.

[0022] The initial positioning and pre-fixing of the protective cover 21 are achieved by the plug-in cooperation between the fixing block 22 and the insert plate 12. This structure guides the protective cover 21 to be accurately positioned during the process of covering the outside of the transmission component 11, avoiding displacement during installation, improving the efficiency of aligning the upper connecting frame 23 with the connecting hole, and simplifying the operation process.

[0023] At the same time, it provides bottom support and lateral restraint for the protective cover 21, effectively suppressing the shaking, deformation or loosening of the protective cover 21 during the operation or transportation of the device, improving the overall structural rigidity and connection stability of the protective component, and ensuring its long-term reliable protection of the transmission component 11.

[0024] In addition, the protective cover 21 may be affected by external impacts or its own weight during use. The plug-in structure transfers part of the load from the protective cover 21 to the lower area of ​​the frame 10, reducing the load-bearing pressure on the upper connecting frame 23 and the pin 26, avoiding local stress concentration, and helping to extend the service life of each connecting component. like Figure 5 As shown, Figure 5The diagram shown is a top view of the structure where the protective cover and the frame work together. The protective cover 21 has a clearance hole 211 at the position corresponding to the drive module 13, allowing the drive module 13 to pass through.

[0025] The clearance hole 211 ensures that the operating end of the drive module 13 can pass through the inside of the protective cover 21 to the outside, so that the operator can still apply force normally after the protective cover 21 is installed in place, without affecting the function of the device.

[0026] The size and shape of the clearance hole 211 match the protruding part of the drive module 13. While ensuring the operating space, the opening area is minimized as much as possible, which can effectively reduce the risk of external dust and rainwater entering the interior of the protective cover 21 through the opening. Moreover, the setting of the clearance hole 211 can intuitively expose the position of the drive module 13, which serves as a visual and structural alignment benchmark when installing the protective cover 21. This effectively guides the protective cover 21 to quickly align with the installation position, avoiding repeated adjustments due to obstruction, thereby improving assembly efficiency and accuracy.

[0027] Working principle: When installing the protective cover 21, bring it close to the transmission assembly 11 from one side opening. First, align the slot on the bottom fixing block 22 of the protective cover 21 with the insert plate 12 at the lower end of the frame 10. Initial positioning and pre-fixation of the protective cover 21 are achieved through this insertion. After the insert plate 12 and slot are inserted, continue adjusting the position of the protective cover 21 so that its clearance hole 211 aligns with the drive module 13, ensuring the drive module 13 passes through smoothly and avoids interference. Once the protective cover 21 is in place... Rotate the L-shaped connecting bracket 23, which is set on the side wall of the frame 10, so that its free end rotates toward the protective cover 21, and gradually presses one side of the protective cover 21 onto the frame 10 to achieve clamping and fixing. When the connecting bracket 23 rotates to the locking position, the second connecting hole 25 on it is aligned with the first connecting hole 24 on the protective cover 21. Insert the pin 26 into the two holes and tighten the pin 26 through the threaded engagement to make it axially tightened, thereby firmly locking the protective cover 21 onto the frame 10 to prevent loosening or falling off.

[0028] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
