Description

Technical Field

[0001] This invention relates to the field of tunnel construction technology, specifically a tunnel construction trolley. Background Technology

[0002] China has one of the largest numbers of railway and highway tunnels in the world, with the longest total length. In the coming decades, my country will build a large number of new railways and highways, including many mountain railways and highways. Some of these tunnels are located in areas with very complex terrain and geological conditions, serious adverse geological phenomena, and poor construction conditions. If the level of mechanization and automation in tunnel construction is not improved, it will be difficult to increase the construction speed of tunnels, which will inevitably affect the development of tunnel construction.

[0003] However, the above technical solutions still have the following drawbacks: traditional tunnel construction trolley operating platforms are mostly of fixed height. Although they are equipped with multiple operating platforms, some heights are still inconvenient for construction personnel to use. Furthermore, existing construction trolleys lack the ability to adjust the construction height and range, which makes it difficult to use the device. Summary of the Invention

[0004] The purpose of this invention is to provide a tunnel construction trolley that solves the problem that tunnel construction trolleys in general technology are not convenient for adjusting the construction height and range.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: The tunnel construction trolley includes: a vehicle body, sliding seats, and a construction platform. The vehicle body has two base plates, on which a bidirectional screw is rotatably mounted. One of the base plates is fixedly mounted with a drive motor for driving the bidirectional screw. There are two sliding seats, which are slidably mounted on both ends of the bidirectional screw and can move towards or away from each other under the drive of the bidirectional screw. There are two construction platforms, and each construction platform is mounted on one of the sliding seats via multiple telescopic columns. Two opposing guardrails are fixedly mounted on the upper surface of the construction platform. One end of each guardrail has an installation groove. One end of the construction platform is fixedly mounted with a fixing rod for installing a ladder. The ladder has a bent section, which can be slidably mounted inside the installation groove to serve as a guardrail.

[0006] The beneficial effects are as follows: by setting a drive motor on the vehicle body to drive the bidirectional screw, setting two sliding seats at each end of the bidirectional screw, and setting telescopic columns on the sliding seats to install the construction platform, and setting multiple support rods with wheels at the bottom of the sliding seats, it is possible to move the sliding seats while ensuring the structural stability of the sliding seats, thereby facilitating the adjustment of the height and working range of the construction platform by construction personnel, thus achieving the purpose of easy adjustment and use.

[0007] A further technical solution of the present invention is that an extension plate is fixedly installed on the bottom of one of the construction platforms, and a reinforcing plate is fixedly installed on the bottom of the other construction platform. A sliding groove for installing the extension plate is formed between the reinforcing plate and the construction platform. The extension plate is always slidably installed inside the sliding groove.

[0008] A further technical solution of the present invention is that a first mounting plate is fixedly installed at both ends of the upper surface of the two base plates, and a bidirectional screw is rotatably installed inside the two first mounting plates at the same end of the two base plates.

[0009] A further technical solution of the present invention is that two drive motors are fixedly installed on the upper surface of one of the base plates by means of a support block.

[0010] A further technical solution of the present invention is that the two base plates are connected by three connecting strips, and two second mounting plates are fixed on the two connecting strips at the edges, and the two second mounting plates are used to reinforce the two bidirectional screws respectively.

[0011] The beneficial effect is that the central part of the bidirectional screw is rotated and installed inside the mounting plate, which can strengthen the bidirectional screw and improve its support capacity.

[0012] A further technical solution of the present invention is that a plurality of rollers for moving the two base plates are installed on the bottom of each base plate.

[0013] A further technical solution of the present invention is that two sets of connecting plates are fixedly installed at the bottom of each sliding seat, and the two sets of connecting plates are respectively threaded onto the same end of two bidirectional screws.

[0014] A further technical solution of the present invention is that support rods are fixedly installed at both ends of the bottom of the sliding seat, and a rotating wheel is rotatably installed at the bottom of the support rod. One end of the rotating wheel moves on the base plate, and the other end of the rotating wheel moves on the base plate and the connecting strip in the middle as the sliding seat moves.

[0015] The beneficial effect is that the support rods with wheels at both ends support the sliding seat, which can improve the stability and load-bearing capacity of the sliding seat.

[0016] A further technical solution of the present invention is that a fixing rod is fixedly installed at one end of the construction platform through two connecting blocks.

[0017] A further technical solution of the present invention is that the middle part of the bending section is arc-shaped, the end of the bending section is parallel to the ladder, the inner circumferential wall of the middle part of the bending section is in contact with the fixing rod, and the end of the bending section is in contact with the end of the construction platform.

[0018] The beneficial effect is that it can prevent the ladder from rotating on the fixed pole, which would affect the safety of workers climbing. Attached Figure Description

Detailed Implementation

[0026] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0027] like Figures 1-4As shown, a tunnel construction trolley includes a vehicle body 1 with two base plates 11 located at both ends of the vehicle body 1. First mounting plates 12 are fixedly installed at both ends of the upper surface of each base plate 11. A bidirectional screw 13 is rotatably installed inside the two first mounting plates 12 at the same end of each base plate 11. Two drive motors 15 are fixedly installed on the upper surface of one of the base plates 11 via support blocks 14. The two drive motors 15 drive the two bidirectional screws 13 respectively. Sliding seats 2 are threaded onto both ends of each bidirectional screw 13. There are two sliding seats 2, which can move towards or away from each other under the drive of the two bidirectional screws 13. Construction platforms 22 are installed on the upper surfaces of each sliding seat 2 via telescopic columns 21. Each construction platform 22 has at least two telescopic columns 21 at its bottom, allowing construction personnel to easily adjust the height and position of the construction platform 22 for construction purposes.

[0028] The two base plates 11 are connected by three connecting strips 111. Two second mounting plates 112 are fixed on the two connecting strips 111 at the edge. The two second mounting plates 112 are used to install the two bidirectional screws 13. The middle part of the bidirectional screw 13 is rotatably installed inside the mounting plate 112, thereby reinforcing the bidirectional screw 13 to improve its support capacity. Multiple rollers 16 for moving the two base plates 11 are installed at the bottom of each base plate 11.

[0029] like Figure 3 and Figure 5 As shown, two sets of connecting plates 201 are fixedly installed on the bottom of the sliding seat 2. Each set of connecting plates 201 has at least one plate. The two sets of connecting plates 201 are threaded onto the same end of two bidirectional screws 13, so that the sliding seat 2 can be moved under the simultaneous drive of the two bidirectional screws 13. Support rods 202 are fixedly installed at both ends of the bottom of the sliding seat 2. A rotating wheel 203 is rotatably installed on the bottom of the support rod 202. One of the rotating wheels 203 moves on the base plate 11, and the other wheel 203 moves on the base plate 11. 03 As the sliding seat 2 moves, it moves on the base plate 11 and the connecting strip 111 in the middle. The support rod 202 with wheels 203 at both ends supports the sliding seat 2, which can improve the stability and load-bearing capacity of the sliding seat 2. It is conceivable that a two-way screw 13 can be set in the middle of the two base plates 11, and the support rod 202 at the bottom of the other end of the sliding seat 2 can be set at the edge, so that the wheel 203 at the bottom of the support rod 202 moves on the connecting strip 111 at the two edges.

[0030] like Figure 3As shown, an extension plate 23 is fixedly installed on the bottom of one of the construction platforms 22, and a reinforcing plate 24 is fixedly installed on the bottom of the other construction platform 22. There are two reinforcing plates 24, both of which are L-shaped, and the longer ends of the two reinforcing plates 24 correspond to each other, so that a sliding groove for installing the extension plate 23 is formed between the longer side of the reinforcing plate 24 and the construction platform 22. The extension plate 23 is always slidably installed inside the sliding groove, which makes it easy for construction personnel to move from one construction platform 22 to another for construction.

[0031] like Figures 1-3 and Figure 6 As shown, a guardrail 25 is fixedly installed on the upper surface of the construction platform 22. Each guardrail 25 has an installation groove 251 extending along its height direction at one end. A fixing rod 26 is fixedly installed at one end of the construction platform 22 via two connecting blocks 261. A ladder 27 is hooked onto the fixing rod 26. The top of the ladder 27 has a bent section 271, the middle of which is arc-shaped. The end of the bent section 271 is parallel to the ladder 27. When the ladder 27 is installed on the fixing rod 26, the inner circle of the middle of the bent section 271... The perimeter wall and the fixed rod 26 fit together, and the end of the bent section 271 fits together with the end of the construction platform 22, thereby preventing the ladder 27 from rotating on the fixed rod 26 and affecting the safety of workers climbing. When the construction workers climb to the construction platform 22, the end of the bent section 271 can be inserted into the interior of one of the mounting slots 251 to use the ladder 27 as a guardrail to protect the safety of the construction workers. The other end of the ladder 27 can be reinforced by threading ropes or the like through the mounting slot 251 of the other guardrail plate 25.

[0032] During use, the vehicle body 1 is first moved to the tunnel construction location by a trailer. Construction workers climb onto the construction platform 22 using the ladder 27 and install the ladder 27 inside the guardrail 25 as a guardrail. Then, the position of the construction platform 22 is adjusted as needed. As construction progresses, the height of the construction platform 22 is adjusted by the telescopic column 21 on the upper surface of the sliding seat 2. Construction workers can move to another construction platform 22 for construction using the extension plate 23. Alternatively, two groups of construction workers can work on two construction platforms 22 simultaneously.

[0033] In this specific embodiment, a drive motor 15 is installed on the vehicle body 1 to drive the bidirectional screw 13. Two sliding seats 2 are respectively installed at both ends of the bidirectional screw 13. A telescopic column 21 is installed on the sliding seat 2 to install the construction platform 22. Multiple support rods 202 with rotating wheels 203 are installed at the bottom of the sliding seat 2. The sliding seat 2 can be moved while ensuring the structural stability of the sliding seat 2, so that the construction personnel can adjust the height and working range of the construction platform 22, thus achieving the purpose of easy adjustment and use.
