Description

Technical Field

[0001] The present invention relates to the field of tunnel drilling construction, and particularly to a transportation turning device for drilling construction in a tunnel. Background Art

[0002] During tunnel drilling construction, transport vehicles enter the tunnel mainly to transport muck or building materials. A large amount of muck is generated during the tunnel excavation process, and transport vehicles are required to transport the muck out of the tunnel to keep the working space in the tunnel unobstructed and facilitate subsequent construction. If the muck cannot be transported out in time, it will accumulate in the tunnel, not only occupying space but also affecting the normal operation of construction equipment. And a large amount of materials such as concrete, steel, and anchor bolts need to be transported into the tunnel by transport vehicles to provide the necessary material basis for construction links such as tunnel excavation, initial support, and secondary lining. For example, during lining construction, a concrete transport vehicle needs to transport concrete to the working surface for pouring the lining structure to ensure the stability and safety of the tunnel.

[0003] Currently, during tunnel drilling construction, the internal space of the tunnel is relatively narrow, and there is not enough space for vehicles to turn around as on an open road surface. The cross-sectional area of the tunnel is designed according to construction requirements, safety codes, etc., mainly to ensure the construction passage and the necessary space for equipment and material transportation, and it is difficult to have a large enough area for vehicle turning.

[0004] The inconvenience of vehicle turning around makes the turnover time of vehicle round trips longer, and materials cannot be quickly transported into the tunnel or muck transported out of the tunnel. For example, in shield construction, if the muck truck cannot turn around and leave in time, subsequent vehicles cannot enter, and the shield machine will pause tunneling due to muck accumulation, slowing down the overall construction progress.

[0005] At the same time, due to the difficulty of turning around, the vehicle may need to repeatedly adjust its position or reverse in the tunnel, which will consume more fuel or electricity and increase construction costs. Moreover, when the vehicle cannot turn around smoothly, it is very likely to cause congestion in the tunnel, affecting the normal passage of other vehicles. Especially in the case of multiple vehicles operating simultaneously, once a vehicle needs to turn around but is stalled due to space problems, the entire transportation passage will be paralyzed. Summary of the Invention

[0006] In order to solve the problem that during the drilling construction of existing tunnels, the internal space of the tunnel is relatively narrow, and it is difficult to have a large enough area for vehicle turning around, resulting in subsequent vehicles being unable to enter and slowing down the overall construction progress, the present invention provides a transportation turning device for drilling construction in a tunnel.

[0007] The technical solution of the present invention is as follows:

[0008] A tunneling drilling construction transportation steering device, the tunneling drilling construction transportation steering device comprising a tractor platform, a steering pedestal, a fixed pedestal and a steering contraction mechanism;

[0009] The upper part of the tractor platform is rotatably connected to the steering pedestal, and the upper part of the tractor platform is fixedly connected to the fixed pedestal. The steering pedestal and the fixed pedestal are connected by a steering contraction mechanism, and the steering contraction mechanism drives the steering pedestal to move along an arc trajectory above the tractor platform. The fixed pedestal is arranged above the tractor platform near the left edge of the tractor platform, and the tractor platform and the fixed pedestal are integrally and fixedly connected;

[0010] Uphill plates are respectively fixedly connected to one side of the heads of the steering pedestal and the fixed pedestal, and the length of the uphill plate is the same as the width of the steering pedestal and the fixed pedestal. Grooves for installing the steering contraction mechanism are formed at the tails of the steering pedestal and the fixed pedestal. Among them, an oil cylinder is installed in the groove of the fixed pedestal. An included angle is formed between the oil cylinder and the long side of the fixed pedestal, and the oil cylinder is fixedly connected to one end of the steering contraction mechanism. The oil cylinder push rod of the oil cylinder is used to push the steering contraction mechanism to move;

[0011] When the oil cylinder push rod of the oil cylinder extends to the maximum distance, the two sides of the steering contraction mechanism are in a symmetrical structure, and the steering pedestal and the fixed pedestal are in a parallel structure side by side. At this time, the head of the transport vehicle on the steering pedestal is set in the forward direction of the tunneling drilling construction transportation steering device;

[0012] When the oil cylinder push rod of the oil cylinder retracts to the minimum distance, the steering contraction mechanism drives the steering pedestal to rotate on the tractor platform, so that the steering pedestal and the fixed pedestal are on the same vertical line, and the tails of the steering pedestal and the fixed pedestal are aligned, and there is a gap at the alignment. At this time, the head of the transport vehicle on the steering pedestal is set in the reverse direction of the tunneling drilling construction transportation steering device, so that the transport vehicle on the steering pedestal is transported above the fixed pedestal, and the transport vehicle drives away from the fixed pedestal.

[0013] Further, the steering contraction mechanism includes a left curved rod, a right curved rod, a shaft body hinge joint, a short side hinge joint, a long side hinge joint, a pin shaft and a slider;

[0014] The number of the left curved rods and the right curved rods is at least two, and the left curved rods and the right curved rods are arranged in a staggered and vertically stacked manner. Axial body hinge joints are respectively installed near the middle positions of the left curved rods and the right curved rods. Short-side hinge joints are respectively fixedly connected to the short sides of the left curved rods and the right curved rods, and long-side hinge joints are respectively fixedly connected to the long sides of the left curved rods and the right curved rods. After the axial holes of the axial body hinge joints of the left curved rods and the right curved rods are aligned, a pin shaft is inserted into the axial body hinge joints, and the left curved rods and the right curved rods are rotationally connected through the pin shaft, thereby driving the steering pedestal to rotate.

[0015] Further, the short-side hinge joint of the left curved rod is arranged in the groove body of the steering pedestal;

[0016] The long-side hinge joint of the left curved rod is arranged in the groove body of the fixed pedestal, and the long-side hinge joint of the left curved rod is fixedly connected to the slider. The slider is arranged in the sliding groove, and the slider moves along the sliding groove.

[0017] Further, the short-side hinge joint of the right curved rod is arranged in the groove body of the fixed pedestal;

[0018] The long-side hinge joint of the right curved rod is arranged in the groove body of the steering pedestal, and the long-side hinge joint of the right curved rod is fixedly connected to the slider. The slider is arranged in the sliding groove, and the slider moves along the sliding groove.

[0019] Further, a joint is installed at the end of the slider in the fixed pedestal, and the joint is connected to the oil cylinder push rod of the oil cylinder. The slider in the fixed pedestal is pushed by the oil cylinder push rod of the oil cylinder.

[0020] Further, a set of rolling mechanisms are also included under the steering pedestal. A set of the rolling mechanisms are arranged in a parallel structure under the steering pedestal.

[0021] Further, the rolling mechanism includes balls, a pressing plate, a quick-release structure and a locking plate;

[0022] The balls are arranged in the arc groove of the steering pedestal and the conical groove of the pressing plate, and the locking plate passes through the insertion hole of the pressing plate;

[0023] A locking hole with a through structure is opened in the transverse direction of the locking plate, and the quick-release structure is used in cooperation with the locking plate to fix the pressing plate;

[0024] Further, the quick-release structure includes an insertion frame, a stop block, a front clamping plate, a rear clamping plate, an L-shaped sliding groove and a rotating shaft for connecting the front clamping plate and the rear clamping plate;

[0025] The stop block is vertically connected to the horizontal plate surface of the insertion frame. The front clamping plate and the rear clamping plate are rotationally connected to the insertion frame. The L-shaped sliding grooves are symmetrically opened on the two longitudinal plates of the insertion frame, and the rotating shaft of the rear clamping plate is inserted into the L-shaped sliding groove;

[0026] The cross-section of the insertion rack is a U-shaped structure, and the insertion rack is inserted into the lock hole of the lock plate.

[0027] Furthermore, a buffer platform is fixedly connected to the end of the tractor platform. The buffer platform is arranged below the uphill plate of the fixed pedestal, and the slope of the buffer platform is the same as that of the uphill plate.

[0028] Furthermore, a set of wheels is connected to the bottom of the tractor platform, and a hydraulic support leg is installed between the set of wheels.

[0029] The present invention has the following effects compared with the prior art:

[0030] By arranging a tunneling drilling construction transportation steering device in the tunnel, the present invention can improve the transportation efficiency. During the tunneling construction process, the transportation vehicle can quickly turn around, reducing the transportation time, and thus accelerating the turnover of materials and equipment.

[0031] The entire turning-around work of the transportation vehicle of the present invention is completed entirely by the tunneling drilling construction transportation steering device in the tunnel, enabling the transportation vehicle to quickly complete the turning-around work in the tunnel, avoiding the large blind spots in the line of sight when the vehicle reverses in a relatively narrow space such as a tunnel, which is likely to cause accidents such as collisions. By means of this device, the vehicle can change direction by driving forward, reducing the accident risk.

[0032] The present invention is provided with a rolling mechanism. By arranging the rolling mechanism, the friction force during the movement of the steering pedestal can be reduced.

[0033] At the same time, the pressing plate of the rolling mechanism is an independent structure. When a certain ball in the middle position is severely worn, the pressing plate of the rolling mechanism can be quickly disassembled through the quick-release structure, facilitating the replacement of the ball.

[0034] When the quick-release structure of the present invention locks the pressing plate to the lock plate, first rotate the front clamping plate and the rear clamping plate into the insertion rack, so that a linear structure is formed between the front clamping plate and the rear clamping plate and the insertion rack. Pass the quick-release structure through the lock hole of the lock plate. When the front clamping plate of the quick-release structure passes through the lock hole of the lock plate, one side of the front clamping plate is limited by the stop block, and the lock plate limits the other side of the front clamping plate. Then slide the rear clamping plate along the L-shaped chute so that the rear clamping plate slides into the longitudinal groove of the L-shaped chute. At this time, a vertical structure is formed between the rear clamping plate and the insertion rack, and the lock plate is arranged between the front clamping plate and the rear clamping plate. The installation and disassembly between the lock plate and the pressing plate can be quickly completed without the aid of other tools.

[0035] When the present invention is reused, the first transport vehicle enters the steering pedestal. The oil cylinder drives the slider in the fixed pedestal to slide in the chute through the oil cylinder push rod, and drives the right curved rod of the steering contraction mechanism to move through the left curved rod, so that the steering pedestal rotates counterclockwise on the tractor platform. When the oil cylinder push rod of the oil cylinder retracts to the minimum distance, the steering pedestal rotates to the maximum distance, and a longitudinal linear structure is formed between the steering pedestal and the fixed pedestal. At this time, the transport vehicle at the head rotates 180 degrees through the steering pedestal, and the transport vehicle on the steering pedestal drives onto the fixed pedestal. After the transport vehicle drives away from the steering pedestal, when the oil cylinder drives the oil cylinder push rod to contract, the steering contraction mechanism drives the steering pedestal to rotate counterclockwise, resetting the steering pedestal so that the steering pedestal and the fixed pedestal are arranged side by side and parallel. The second transport vehicle drives onto the steering pedestal. After the first transport vehicle is loaded, it drives away from the fixed pedestal and exits the tunnel from one side of the tunnel. On the other side of the tunnel, the transport vehicles to be loaded can queue up to wait to enter the steering pedestal for a U-turn. Through the above structure, the transport vehicles on both sides of the tunnel can make U-turns in an orderly manner, leaving a waiting area for transport vehicles on one side of the tunnel, so as to ensure that multiple transport vehicles can continuously make U-turns and loading operations in the tunnel, improving the transport efficiency of the transport vehicles.

[0056] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments in conjunction with the accompanying drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention, but are not used to limit the scope of the present invention.

[0057] Detailed implementation manner one: In combination with Figure 1 — Figure 3Describing this embodiment, a tunneling drilling construction transportation steering device of this embodiment, the tunneling drilling construction transportation steering device includes a tractor platform 1, a steering pedestal 2, a fixed pedestal 3 and a steering contraction mechanism 4;

[0058] There is a rotational connection between the upper part of the tractor platform 1 and the steering pedestal 2, and a fixed connection between the upper part of the tractor platform 1 and the fixed pedestal 3. The steering pedestal 2 and the fixed pedestal 3 are connected by the steering contraction mechanism 4, and the steering contraction mechanism 4 drives the steering pedestal 2 to move along an arc trajectory above the tractor platform 1. The fixed pedestal 3 is arranged above the tractor platform 1 near the left edge position of the tractor platform 1, and there is an integral fixed connection between the tractor platform 1 and the fixed pedestal 3;

[0059] Uphill plates 5 are respectively fixedly connected to one side of the heads of the steering pedestal 2 and the fixed pedestal 3, and the length of the uphill plate 5 is the same as the width of the steering pedestal 2 and the fixed pedestal 3. Grooves 6 for installing the steering contraction mechanism 4 are opened at the tails of the steering pedestal 2 and the fixed pedestal 3. Among them, an oil cylinder 7 is installed in the groove 6 of the fixed pedestal 3. There is an angle between the oil cylinder 7 and the long side of the fixed pedestal 3, and the oil cylinder 7 is fixedly connected to one end of the steering contraction mechanism 4. The oil cylinder push rod of the oil cylinder 7 is used to push the steering contraction mechanism 4 to move;

[0060] When the oil cylinder push rod of the oil cylinder 7 extends to the maximum distance, the two sides of the steering contraction mechanism 4 are in a symmetric structure,

[0061] The steering pedestal 2 and the fixed pedestal 3 are in a parallel juxtaposed structure. At this time, the head of the transport vehicle 8 on the steering pedestal 2 is set in the forward direction of the tunneling drilling construction transportation steering device;

[0062] When the oil cylinder push rod of the oil cylinder 7 retracts to the minimum distance, the steering contraction mechanism 4 drives the steering pedestal 2 to rotate on the tractor platform 1, so that the steering pedestal 2 and the fixed pedestal 3 are on the same vertical line, and the tails of the steering pedestal 2 and the fixed pedestal 3 are aligned, and there is a gap at the alignment position. At this time, the head of the transport vehicle 8 on the steering pedestal 2 is set in the reverse direction of the tunneling drilling construction transportation steering device, so that the transport vehicle 8 on the steering pedestal 2 is transported above the fixed pedestal 3, and the transport vehicle 8 drives away from the fixed pedestal 3.

[0063] Specific embodiment two: Combining Figure 4 and Figure 5 Describing this embodiment, for the tunneling drilling construction transportation steering device of this embodiment, the steering contraction mechanism 4 includes a left curved rod 41, a right curved rod 42, a shaft body hinge joint 43, a short side hinge joint 44, a long side hinge joint 45, a pin shaft 46 and a slider 47;

[0064] The number of the left curved rods 41 and the right curved rods 42 is at least two, and the left curved rods 41 and the right curved rods 42 are arranged in a staggered and vertically stacked manner. Shaft body hinge joints 43 are respectively installed near the middle positions of the left curved rods 41 and the right curved rods 42. Short side hinge joints 44 are respectively fixedly connected to the short sides of the left curved rods 41 and the right curved rods 42. Long side hinge joints 45 are respectively fixedly connected to the long sides of the left curved rods 41 and the right curved rods 42. After the shaft holes of the shaft body hinge joints 43 of the left curved rods 41 and the right curved rods 42 are aligned, a pin shaft 46 is inserted into the shaft body hinge joints 43. The left curved rods 41 and the right curved rods 42 are rotationally connected through the pin shaft 46, so as to drive the turntable base 2 to rotate.

[0065] The left curved rods 41 and the right curved rods 42 have the same structure. Among them, during installation, two left curved rods 41 and two right curved rods 42 are arranged in a staggered and stacked manner, so that the centers of the insertion holes of the shaft body hinge joints 43 on the left curved rods 41 and the right curved rods 42 are on the same straight line. At the same time, the pin shaft 46 is inserted into the shaft body hinge joints 43, and the two left curved rods 41 and the two right curved rods 42 are rotationally connected through the pin shaft 46;

[0066] The left curved rod 41 drives the right curved rod 42 to rotate. Since the right curved rod 42 is rotationally connected to the turntable base 2, when the left curved rod 41 drives the right curved rod 42, the turntable base 2 is driven to rotate counterclockwise through the right curved rod 42, and the angle of the turntable base 2 is adjusted through the steering contraction mechanism 4.

[0067] Specific Embodiment 3: Combine Figure 4 — Figure 7 This embodiment is described. For the tunneling drilling construction transportation steering device of this embodiment, the short side hinge joint 44 of the left curved rod 41 is arranged in the groove body 6 of the turntable base 2;

[0068] The long side hinge joint 45 of the left curved rod 41 is arranged in the groove body 6 of the fixed base 3, and the long side hinge joint 45 of the left curved rod 41 is fixedly connected to the slider 47. The slider 47 is arranged in the chute 48, so that the slider 47 moves along the chute 48.

[0069] The groove 6 in the swivel pedestal 2 and the fixed pedestal 3 is a rectangular groove structure. The installation of the swivel retraction mechanism 4 is facilitated by arranging the groove 6 in the swivel pedestal 2 and the fixed pedestal 3. The top and bottom of the groove 6 are respectively provided with sliding grooves 48, and a slider 47 is slidably installed in each sliding groove 48. The slider 47 slides along the sliding groove 48. Among them, the slider 47 in the sliding groove 48 at the upper part of the groove in the fixed pedestal 3 is connected to the hydraulic push rod of the oil cylinder 7. Therefore, when the hydraulic push rod of the oil cylinder 7 pushes the slider 47 in this sliding groove 48, the movement between the left curved rod 41 and the right curved rod 42 is driven by the slider 47 in this sliding groove 48. According to different needs, a push plate can be fixedly connected between the sliders 47 in the upper middle sliding groove 48 and the lower middle sliding groove 48 of the groove 6 in the fixed pedestal 3. A U-shaped structure is formed between the push plate and the two sliders 47. The hydraulic push rod of the cylinder 7 can be fixed at the middle position of the push plate through a joint, so that the cylinder 7 drives the sliders 47 in the upper sliding groove 48 and the lower sliding groove 48 to slide simultaneously.

[0070] Specific Embodiment 4: Combining Figure 4 — Figure 8 To illustrate this embodiment, for the tunneling drilling construction transportation swivel device of this embodiment, the short-side hinge joint 44 of the right curved rod 42 is arranged in the groove 6 of the fixed pedestal 3;

[0071] The long-side hinge joint 45 of the right curved rod 42 is arranged in the groove 6 of the swivel pedestal 2, and a fixed connection is formed between the long-side hinge joint 45 of the right curved rod 42 and the slider 47. The slider 47 is arranged in the sliding groove 48, so that the slider 47 moves along the sliding groove 48.

[0072] The short-side hinge joints 44 on the left curved rod 41 and the right curved rod 42 are integrally and fixedly connected to the left curved rod 41 and the right curved rod 42 respectively. A rotating shaft is inserted into the short-side hinge joints 44 of the left curved rod 41 and the right curved rod 42. The rotating shaft is arranged in the groove 6. The top and bottom of the rotating shaft are fixed in the grooves of the swivel pedestal 2 and the fixed pedestal 3, so that the short-side hinge joints 44 of the left curved rod 41 and the right curved rod 42 rotate along the rotating shaft;

[0073] A rotating shaft penetrates through the long-side hinge joints 45 on the left curved rod 41 and the right curved rod 42. The top and bottom of the rotating shaft are vertically connected to the slider 47. When the slider 47 slides, the rotating shaft on the slider 47 drives the long-side hinge joints 45 on the left curved rod 41 and the right curved rod 42 to move, so that the left curved rod 41 and the right curved rod 42 operate.

[0074] Specific Embodiment 5: Combining Figure 4 — Figure 8To describe this embodiment, for the tunneling drilling construction transportation steering device of this embodiment, a joint is installed at the end of the slider 47 in the fixed pedestal 3 and is connected to the cylinder push rod of the cylinder 7 through the joint, and the slider 47 in the fixed pedestal 3 is pushed by the cylinder push rod of the cylinder 7.

[0075] When the cylinder push rod of the cylinder 7 extends to the maximum distance, both sides of the steering contraction mechanism 4 are in a symmetrical structure.

[0076] The steering pedestal 2 and the fixed pedestal 3 are in a parallel structure side by side. At this time, the front of the transport vehicle 8 on the steering pedestal 2 is set in the forward direction of the tunneling drilling construction transportation steering device.

[0077] When the cylinder push rod of the cylinder 7 retracts to the minimum distance, the steering contraction mechanism 4 drives the steering pedestal 2 to rotate on the tractor platform 1, so that the steering pedestal 2 and the fixed pedestal 3 are on the same vertical line, and the tails of the steering pedestal 2 and the fixed pedestal 3 are aligned, and there is a gap at the alignment. At this time, the front of the transport vehicle 8 on the steering pedestal 2 is set in the reverse direction of the tunneling drilling construction transportation steering device, so that the transport vehicle 8 on the steering pedestal 2 is transported above the fixed pedestal 3, and the transport vehicle 8 drives away from the fixed pedestal 3.

[0078] Specific Embodiment Six: Combine Figure 9 — Figure 12 To describe this embodiment, for the tunneling drilling construction transportation steering device of this embodiment, a set of rolling mechanisms 9 are further included under the steering pedestal 2, and a set of the rolling mechanisms 9 are arranged in a parallel structure under the steering pedestal 2.

[0079] The rolling mechanism 9 is installed at the bottom of the steering pedestal 2. When the steering pedestal 2 rotates, the steering pedestal 2 drives the rolling mechanism 9 to move synchronously. When the steering pedestal 2 rotates on the tractor platform 1, a set of ball bearings 91 on the rolling mechanism 9 roll on the tractor platform 1, thereby reducing the friction between the steering pedestal 2 and the tractor platform 1 and enabling the steering pedestal 2 to work smoothly.

[0080] Specific Embodiment Seven: Combine Figure 9 — Figure 12 To describe this embodiment, for the tunneling drilling construction transportation steering device of this embodiment, the rolling mechanism 9 includes ball bearings 91, pressing plates 92, quick-release structures 93 and locking plates 94;

[0081] The ball bearings 91 are arranged in the arc-shaped groove of the steering pedestal 2 and the conical groove 95 of the pressing plate 92, and the locking plate 94 passes through the jack of the pressing plate 92.

[0082] A locking hole 94-1 with a through structure is formed in the transverse direction of the locking plate 94. The quick-release structure 93 is used in cooperation with the locking plate 94 to fix the pressing plate 92 through the quick-release structure 93.

[0083] The pressing plate 92 is a rectangular structure with a tapered groove 95 formed in the middle. Each ball 91 corresponds to a pressing plate 92. Each pressing plate 92 is an independent structure, and two quick-release structures 93 are correspondingly installed on each pressing plate 92.

[0084] The locking plate 94 is a rectangular plug structure, and the locking plate 94 passes through the jack on the pressing plate 92. The shape of the jack is the same as the cross-sectional shape of the locking plate 94, so as to facilitate passing the locking plate 94 through the pressing plate 92.

[0085] Specific Embodiment VIII: In combination with Figure 13 — Figure 16 Describe this embodiment. The tunneling drilling construction transportation steering device of this embodiment, the quick-release structure 93 includes an insertion frame 93-1, a stop block 93-2, a front clamping plate 93-3, a rear clamping plate 93-4, an L-shaped chute 93-5 and a rotating shaft for connecting the front clamping plate 93-3 and the rear clamping plate 93-4.

[0086] The stop block 93-2 is vertically connected to the horizontal plate surface of the insertion frame 93-1. The front clamping plate 93-3 and the rear clamping plate 93-4 are rotatably connected to the insertion frame 93-1. The L-shaped chute 93-5 is symmetrically formed on the two longitudinal plates of the insertion frame 93-1, and the rotating shaft of the rear clamping plate 93-4 is inserted into the L-shaped chute 93-5.

[0087] The cross-section of the insertion frame 93-1 is a U-shaped structure, and the insertion frame 93-1 is inserted into the locking hole 94-1 of the locking plate 94.

[0088] The insertion frame 93-1 of the quick-release structure 93 is rotatably connected to the front clamping plate 93-3 and the rear clamping plate 93-4 respectively. The widths of the front clamping plate 93-3 and the rear clamping plate 93-4 are smaller than the height of the insertion frame 93-1, so that when the front clamping plate 93-3 and the rear clamping plate 93-4 rotate, the front clamping plate 93-3 and the rear clamping plate 93-4 can rotate into the insertion frame 93-1. The stop block 93-2 mainly plays a role in limiting the front clamping plate 93-3 to prevent the front clamping plate 93-3 from continuing to rotate when it is perpendicular to the insertion frame 93-1.

[0089] When the quick-release structure 93 locks the pressing plate 92 to the locking plate 94, first rotate the front clamping plate 93-3 and the rear clamping plate 93-4 into the insertion frame 93-1, so that a linear structure is formed between the front clamping plate 93-3, the rear clamping plate 93-4 and the insertion frame 93-1. Pass the quick-release structure 93 through the locking hole 94-1 of the locking plate 94. When the front clamping plate 93-3 of the quick-release structure 93 passes through the locking hole 94-1 of the locking plate 94, the front clamping plate 93-3 rotates by its own gravity, so that a vertical structure is formed between the front clamping plate 93-3 and the insertion frame 93-1. One side of the front clamping plate 93-3 is limited by the stop block 93-2, and the locking plate 94 limits the other side of the front clamping plate 93-3. Then slide the rear clamping plate 93-4 along the L-shaped sliding groove 93-5, so that the rear clamping plate 93-4 slides into the longitudinal groove of the L-shaped sliding groove 93-5. At this time, a vertical structure is formed between the rear clamping plate 93-4 and the insertion frame 93-1. At this time, the locking plate 94 is arranged between the front clamping plate 93-3 and the rear clamping plate 93-4, and the locking plate 94 and the pressing plate 92 can be quickly installed and disassembled without the help of other tools. When it is necessary to take out the quick-release structure 93 from the locking hole 94-1, slide the rear clamping plate 93-4 along the L-shaped sliding groove 93-5, so that the rear clamping plate 93-4 slides into the transverse groove of the L-shaped sliding groove 93-5, so that a parallel structure is formed between the rear clamping plate 93-4 and the insertion frame 93-1. Then move the quick-release structure 93 horizontally in the direction of the side of the front clamping plate 93-3, and slide the quick-release structure 93 out of the locking hole 94-1 of the locking plate 94, so that the pressing plate 92 and the locking plate 94 are separated, and the worn ball 91 can be replaced.

[0090] Specific Embodiment Nine: Combining Figure 13 — Figure 16 Describe this embodiment. For the tunneling drilling construction transportation turning device of this embodiment, a buffer platform 10 is fixedly connected to the end of the tractor platform 1. The buffer platform 10 is arranged below the uphill plate 5 of the fixed pedestal 3, and the slope of the buffer platform 10 is the same as that of the uphill plate 5.

[0091] By arranging the uphill plate 5 at the end of the fixed pedestal 3 and the buffer platform 10 at the end of the tractor platform 1, the transport vehicle 8 can drive onto the turning pedestal 2 along the buffer platform 10 and the uphill plate 5.

[0092] Specific Embodiment Ten: Combining Figure 1 — Figure 16 Describe this embodiment. For the tunneling drilling construction transportation turning device of this embodiment, a set of wheel bodies 11 are connected to the bottom of the tractor platform 1, and hydraulic support legs 12 are installed between the set of wheel bodies.

[0093] Working principle:

[0094] During use, the tunneling drilling construction transportation turning device is transported into the tunnel. The turning pedestal 2 and the fixed pedestal 3 of the tunneling drilling construction transportation turning device are arranged in parallel. The first transport vehicle 8 enters the turning pedestal 2 through the gentle slope 10 and the uphill plate 5 of the turning pedestal 2. The oil cylinder 7 is started. The oil cylinder 7 drives the slider 47 in the fixed pedestal 3 to slide in the chute 48 through the oil cylinder push rod. When the slider 47 in the fixed pedestal 3 slides in the chute 48, the shaft member in the slider 47 drives the long-side hinge joint 45 connected to the slider 47 to move, thereby driving the right curved rod 42 of the turning contraction mechanism 4 to move through the left curved rod 41. When the right curved rod 42 moves, the slider 47 in the right curved rod 42 moves along the chute 48, causing the turning pedestal 2 to rotate counterclockwise on the tractor platform 1. When the oil cylinder push rod of the oil cylinder 7 retracts to the minimum distance, the turning pedestal 2 rotates to the maximum distance. The turning pedestal 2 and the fixed pedestal 3 are in a longitudinal linear structure. At this time, the transport vehicle 8 at the head rotates 180 degrees through the turning pedestal 2, and the transport vehicle 8 on the turning pedestal 2 travels onto the fixed pedestal 3. After the transport vehicle 8 drives away from the turning pedestal 2, when the oil cylinder 7 drives the oil cylinder push rod to contract, the turning contraction mechanism 4 drives the turning pedestal 2 to rotate counterclockwise, resetting the turning pedestal 2 so that the turning pedestal 2 and the fixed pedestal 3 are arranged in parallel. The second transport vehicle drives into the turning pedestal 2. After the first transport vehicle 8 is loaded, it drives away from the fixed pedestal 3 and out of the tunnel from one side of the tunnel. On the other side of the tunnel, the transport vehicles 8 to be loaded can queue up to enter the turning pedestal 2 to make a U-turn. Through the above structure, the transport vehicles 8 on both sides of the tunnel can make U-turns in an orderly manner, leaving a waiting area for the transport vehicles 8 on one side of the tunnel, thus ensuring that multiple transport vehicles 8 can continuously make U-turns and loading operations in the tunnel, and improving the transportation efficiency of the transport vehicles 8.
