Description

Technical Field

[0001] This utility model relates to a multi-functional material transport vehicle for tunnel construction, and more particularly to a quick insertion mechanism. Background Technology

[0002] With the continuous development of tunnel construction, construction workers need to transport personnel, tunnel segments, box culverts, cranes, bulk cargo platforms, concrete mixing tanks, muck containers, gravel containers, etc., within tunnels. Correspondingly, personnel compartments, segment supports, box culvert supports, and other devices need to be installed on the vehicle frame. However, the interfaces currently designed on the vehicle body can only accommodate the installation of one or two types of devices, resulting in limited functionality and poor versatility. Furthermore, due to the limited load capacity of a single vehicle, the amount of materials that can be transported in a single trip is limited.

[0003] In summary, traditional tunnel material transport vehicles have limited functionality and low carrying capacity, making it difficult to meet the diverse and high-efficiency needs of current tunnel construction.

[0004] Therefore, this application proposes a quick insertion mechanism, which has a standardized installation interface on the frame of the transport vehicle, and an installation protrusion is provided below the working equipment. During installation, the working equipment is fixed on the frame by the cooperation of the installation protrusion and the installation interface, thereby meeting the transportation needs of different materials.

[0005] During the design process of this solution, the applicant discovered that achieving quick insertion, fixing, unlocking, and separation between the mounting protrusion and the mounting interface was a design challenge. Conventional flange bolt connections are relatively complex to install and disassemble, and cannot meet the need for rapid assembly and disassembly. Utility Model Content

[0006] The purpose of this invention is to provide a quick insertion mechanism to achieve a quick and detachable insertion connection.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] A quick insertion mechanism includes a frame of a transport vehicle and a working device placed on the frame for transport. The frame is provided with an installation interface structure, and the working device is provided with an installation protrusion structure below it. The two can be detachably inserted and connected.

[0009] The installation interface structure includes a conical hole seat with a conical hole that is larger at the top and smaller at the bottom. The top of the conical hole is open, and the bottom of the conical hole is connected to a horizontal channel extending forward and backward. A locking pin is provided in the horizontal channel and slides with it in the forward and backward direction. The locking pin is connected to a locking pin moving mechanism for driving the forward and backward movement of the locking pin.

[0010] The mounting protrusion structure includes a tapered pin that mates with a tapered hole, and the lower end of the tapered pin is fixedly provided with a downwardly extending Latin joint.

[0011] When the mounting protrusion structure and the mounting interface structure are inserted and connected, the tapered pin is located in the tapered hole, and the LASIK passes through the lower end of the tapered hole and enters the horizontal channel; the locking pin moves back and forth to fix or separate the LASIK.

[0012] Furthermore, the Latin pin includes a locking section and a connecting section, with the connecting section fixedly connected to the lower end of the tapered pin; the locking section includes an upper guide portion and a lower limiting portion, the guide portion being an elongated strip extending back and forth, the limiting portion being larger than the guide portion, and the upper side of the limiting portion forming an inclined mating surface.

[0013] The locking pin is provided with a through hole and a guide hole. The shape of the through hole matches the limiting part, and the guide hole extends in the front-back direction and its end communicates with the through hole. The width of the guide hole matches the guide part. The lower side of the locking pin is provided with a wedge surface extending in the front-back direction. The angle of the wedge surface matches the mating surface.

[0014] After the lasing pin enters the horizontal channel, it passes through the perforation and the guide part aligns with the guide hole. When the lasing pin moves backward, its wedge surface wedges tightly against the mating surface of the lasing pin, thus locking. When the lasing pin moves forward, its wedge surface separates from the mating surface of the lasing pin, thus unlocking.

[0015] Furthermore, the locking pin moving mechanism includes a pull rod rotatably connected to the end of the locking pin. The pull rod is located in the horizontal channel and slides with it. The side wall of the horizontal channel is provided with a spiral groove. A cam is fixed on the pull rod and is located in the spiral groove. By rotating the pull rod, the rotational motion is converted into the linear motion of the pull rod, thereby driving the locking pin to move back and forth.

[0016] Furthermore, a handle is fixed to the end of the pull rod.

[0017] Furthermore, the locking pin moving mechanism includes a telescopic rod, the movable end of which is connected to the end of the locking pin.

[0018] The beneficial effects of this utility model are:

[0019] This utility model adopts a quick insertion mechanism to achieve a separable connection between the installation protrusion structure and the installation interface structure, eliminating the complexity of the flange bolt connection method and improving the disassembly and assembly efficiency when different working equipment needs to be replaced.

[0035] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. Detailed Implementation

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0037] Example 1:

[0038] like Figures 1 to 5As shown, this embodiment provides a quick insertion mechanism, including a vehicle frame 10 and a working device placed on the frame for transport. Mounting interface structures 1 are regularly arranged on the vehicle frame 10, and mounting protrusion structures are regularly arranged below the working device. The number of mounting protrusion structures is less than or equal to the number of mounting interface structures, and the planar projection of all mounting protrusion structures falls on the mounting interface structure 1. The corresponding mounting protrusion structures and mounting interface structures 1 can be detachably connected.

[0039] In this embodiment, the mounting interface structure 1 is arranged in a rectangular array, and there is a longitudinal spacing A and a transverse spacing B between the mounting interface structures.

[0040] In this embodiment, the working device is a human cabin. The human cabin has longitudinally and laterally distributed mounting protrusions below it. The longitudinally distributed mounting interface structures are spaced by n*A and K*A longitudinally, and the laterally distributed mounting interface structures are spaced by B longitudinally, where n and K are integers.

[0041] During the installation of the man-in-flight compartment, the mounting protrusions on the man-in-flight compartment are engaged with the corresponding mounting interface structure 1 on the chassis to achieve insertion and fixation.

[0042] like Figures 6 to 15 As shown, the mounting protrusion structure and the mounting interface structure work together to form a quick insertion mechanism, enabling quick and detachable insertion connection, thereby achieving insertion and fixation of both, as well as unlocking and separation.

[0043] Specifically, the mounting protrusion structure includes a tapered pin 13 fixedly connected to the working equipment, and a downwardly extending Latin strip 14 is fixedly provided at the lower end of the tapered pin 13.

[0044] Latin 14 includes a locking section and a connecting section 15. The connecting section 15 is fixedly connected to the lower end of the tapered pin 13. The locking section includes an upper guide section 16 and a lower limiting section 17. The guide section 16 is an elongated strip extending back and forth. The limiting section 17 is cylindrical and has a diameter larger than that of the guide section 16. An inclined mating surface 141 is formed on the upper side of the limiting section 17.

[0045] Specifically, the mounting interface structure includes a tapered hole seat 11 fixedly connected to the frame 10. The tapered hole seat 11 has a tapered hole that is larger at the top and smaller at the bottom. The tapered hole mates with a tapered pin 13. The upper end of the tapered hole is open, and the lower end of the tapered hole communicates with a horizontal channel extending forward and backward. A locking pin 12 is provided in the horizontal channel and slides with it in the forward and backward direction. The locking pin 12 is connected to a locking pin moving mechanism for driving the forward and backward movement of the locking pin 12.

[0046] The locking pin 12 is provided with a through hole 18 and a guide hole 19. The shape of the through hole 18 matches the limiting part 17. The guide hole 19 extends in the front-back direction and its end is connected to the through hole 18. The width of the guide hole 19 matches the guide part 16. The lower side of the locking pin 12 is provided with a wedge surface 121 extending in the front-back direction. The angle of the wedge surface 121 matches the mating surface 141.

[0047] In this embodiment, the locking pin moving mechanism includes a pull rod 122 rotatably connected to the end of the locking pin 12. The pull rod 122 is located in and slidably engages with the horizontal channel. The side wall of the horizontal channel is provided with a helical groove. A cam is fixed on the pull rod and is located in the helical groove. By rotating the handle 123 at the end of the pull rod 122, the rotational motion is converted into the linear motion of the pull rod 122, thereby driving the locking pin 12 to move back and forth.

[0048] During the insertion connection of the mounting protrusion structure and the mounting interface structure, the tapered pin 13 falls into the tapered hole, and the lasing pin 14 passes through the lower end of the tapered hole and enters the horizontal channel; after entering the horizontal channel, the lasing pin 14 passes through the through hole 18 and the locking pin 12, while the guide part 16 aligns with the guide hole 19. Rotating the handle 123 causes the locking pin 12 to move forward. Figure 8 (Left is front) so that the wedge surface of the locking pin 12 is wedged tightly against the mating surface 141 of the Latin 14 (at this time, the guide part 16 is located in the guide hole 19), completing the locking. Rotating the handle 123 in the opposite direction causes the locking pin 12 to move backward ( Figure 8 (Right side of the middle is the back side), so that the wedge surface 121 of the locking pin 12 separates from the mating surface 141 of the Latin pin 14, completing the unlocking. At this time, the guide part 16 and the guide hole 19 are aligned vertically, and the Latin pin 14 and the tapered pin 13 can be moved upward, thereby separating from the tapered hole seat 11.

[0049] Example 2:

[0050] In this embodiment, the locking pin moving mechanism includes a telescopic rod, the movable end of which is connected to the end of the locking pin.
