Description

Technical Field

[0001] This utility model relates to the field of tunnel construction technology, and in particular to a tunnel construction passing platform. Background Technology

[0002] During tunnel construction, the drill-and-blast method is typically used to excavate tunnel sections. This involves drilling holes for explosives on the surface of the excavated section, then using explosives to open it up. Afterward, repairs are carried out inside the opened tunnel. Before and during repairs, transport vehicles are often needed to remove the soil and rock from the tunnel section. However, due to the size limitations inside the tunnel, such as… Figure 1 As shown, generally only one transport vehicle can travel back and forth inside the tunnel to transport the rock and soil, which is very time-consuming and reduces construction efficiency. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a tunnel construction passing platform to address the shortcomings of the prior art. By raising the vehicle, the space for vehicle travel is expanded, thereby enabling vehicles to travel in two directions within the tunnel.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a tunnel construction passing platform, including an upper support plate, a lower support plate, a track and multiple vertical supports, wherein the width of the upper support plate is greater than the width of the lower support plate, and the upper support plate and the lower support plate are connected by the multiple vertical supports;

[0005] The upper support plate has a longitudinal limiting plate on its left and right sides along its length direction. Each end of the two limiting plates is detachably connected to a locking rod. The upper support plate has two first through slots along its length direction. The direction of the first through slots is set along the width direction of the upper support plate.

[0006] The lower support plate has two second through slots along its length and the second through slots are arranged along the width of the lower support plate. The lower surface of the lower support plate is provided with multiple universal rollers through hydraulic rods, and each hydraulic rod is connected to one of the universal rollers.

[0007] The track passes through two of the first through slots and two of the second through slots, and the thickness of the track is the same as the height of the omnidirectional roller.

[0008] Furthermore, one end of the locking rod is hinged to the surface of the limiting plate, and the other end of the locking rod is detachably connected to the limiting plate.

[0010] Furthermore, each of the two limiting plates has a number of second balls on its opposite side, and the upper support plate also has a number of second balls on its two sides along its length.

[0011] Furthermore, several third ball bearings are respectively provided on the two sides along the length of the lower support plate.

[0012] Furthermore, the upper support plate is detachably connected to a ramp frame at both ends along its length.

[0013] Furthermore, the slope frame includes a slope panel and a bottom support plate, with the bottom end of the slope panel and the upper surface of the bottom support plate fixedly connected, and the slope panel and the bottom support plate forming a set angle.

[0014] Furthermore, the bottom of the bottom support plate has a fixing hole for passing a fixing bolt.

[0015] Furthermore, a support rod is connected between the lower surface of the slope panel and the upper surface of the bottom support plate.

[0016] Furthermore, the free end of the bottom support plate is detachably connected to the end face of the lower support plate along its length.

[0017] This utility model has the following advantages compared with the prior art:

[0018] This utility model provides a tunnel construction passing platform. Through the upper and lower support plates and the vertical support between them, the vehicle is raised, thereby expanding the vehicle's driving space. By using a limiting plate and locking rod to restrain the vehicle on the upper support plate, and by rotating the tracks driven by the vehicle's wheels, the passing platform can move forward or backward, thus completing the transportation of vehicles. This allows vehicles to travel in two directions within the tunnel, improving the efficiency of rock and soil transportation within the tunnel.

[0027] like Figure 1-5 As shown, the present invention provides a tunnel construction passing platform, including an upper support plate 10, a lower support plate 2, a track 3, and a plurality of vertical supports 12. The width of the upper support plate 10 is greater than the width of the lower support plate 2, and the upper support plate 10 and the lower support plate 2 are connected by the plurality of vertical supports 12.

[0028] The upper support plate 10 has a longitudinal limiting plate 11 on its left and right sides along its length direction. Each end of the two limiting plates 11 is detachably connected to a locking rod 9. The upper support plate 10 has two first through slots 8 along its length direction. The direction of the first through slots 8 is set along the width direction of the upper support plate 10.

[0029] The lower support plate 2 has two second through slots 13 along its length direction. The second through slots 13 are arranged along the width direction of the lower support plate 2. The lower surface of the lower support plate 2 is provided with multiple universal rollers 4 through hydraulic rods. Each hydraulic rod is connected to one of the universal rollers 4.

[0030] The track 3 passes through two first through slots 8 and two second through slots 13 respectively, and the thickness of the track 3 is the same as the height of the universal roller 4.

[0031] During construction, before the transport vehicle enters the tunnel section, the position of the passing platform of this utility model is fixed at the tunnel entrance. Then, by building a slope panel frame 7, a foundation is created for the transport vehicle 1 to run onto the upper support plate 10. Then, the transport vehicle 1 runs onto the upper support plate 10, and the two locking rods 9 at the front and rear of the transport vehicle 1 are connected to the limiting plate 11 to fix the position of the transport vehicle 1. At this time, as the transport vehicle 1 goes onto the upper support plate 10, a device is installed on the wheels of the transport vehicle 1 to enable the wheels to drive the track 3. After the position of the transport vehicle 1 is relatively fixed with the position of the upper support plate 10, the track 3 can be rotated by driving the wheels of the transport vehicle 1, thereby moving the passing platform.

[0032] When the passing platform moves in front of the transport vehicle 1, the transport vehicle 1 needs to reverse, that is, the wheels of the transport vehicle 1 need to rotate backward so that the transport vehicle 1 and the passing platform can move forward.

[0033] Upon reaching the destination, the hydraulic rod is first raised upwards by the operator, which allows the track 3 to leave the ground. Then, under the action of the omnidirectional rollers 4, the head of the passing platform is shifted. The hydraulic rod is then retracted, the ramp frame 7 is erected, and the two locking levers 9 at the front and rear of the transport vehicle 1 are opened, allowing the transport vehicle 1 to leave the passing platform.

[0034] This allows two vehicles to operate simultaneously during transportation, increasing the number and frequency of transport vehicles 1, thereby improving construction efficiency.

[0035] In this utility model, for ease of use during construction, one end of the locking rod 9 is hinged to the surface of the limiting plate 11, and the other end of the locking rod 9 is detachably connected to the limiting plate 11.

[0036] Meanwhile, to improve the convenience of operation between the passing platform and the tunnel, reduce the interaction force between the passing platform and the transport vehicle 1, and protect the outer surface of the vehicle as well as the inner surface of the tunnel wall, this utility model improves alignment by using ball bearings. Specifically, several first ball bearings 15 are provided on the opposite sides of the two limiting plates 11. Several second ball bearings 14 are provided on the opposite sides of the two limiting plates 11, and several second ball bearings 14 are also provided on the two sides along the length of the upper support plate 10. Several third ball bearings 16 are provided on the two sides along the length of the lower support plate 2.

[0037] The slope frame 7 described above can be a temporary board or a frame, as long as it is a sloping surface that allows the wheels of the transport vehicle 1 to get onto the upper support plate 10. Specifically, the slope frame 7 is detachably connected to both ends of the upper support plate 10 in the length direction.

[0038] This utility model provides a specific structure for a slope support frame 7, which includes a slope panel and a bottom support plate. The bottom end of the slope panel and the upper surface of the bottom support plate are fixedly connected, and the slope panel and the bottom support plate form a set angle. The set angle is determined according to the actual construction, and is generally 30 degrees.

[0039] Meanwhile, a fixing hole 5 is provided at the bottom of the bottom support plate, and the fixing hole 5 is used for fixing bolts to pass through. By providing the fixing hole 5, the bolts pass through the fixing hole 5 and are fixed to the ground, thereby fixing the position of the slope frame 7 and increasing the stability of the slope frame 7.

[0040] A support rod 6 connects the lower surface of the slope panel and the upper surface of the bottom support plate. This ensures the stability of the slope frame 7 and guarantees the safe operation of the transport vehicle 1.

[0041] The free end of the bottom support plate is detachably connected to the end face of the lower support plate 2 along its length. This connection method makes the ramp frame 7 more stable during use, ensuring that its position does not change and guaranteeing the safe operation of the transport vehicle 1.

[0042] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the present utility model. Any simple modifications, alterations, or equivalent structural changes made to the above embodiments based on the technical essence of the present utility model shall still fall within the protection scope of the present utility model.
