Abstract
Description
Technical Field
[0001] This utility model is specifically a trolley translation mechanism, which relates to the field of tunnel construction equipment technology. Background Technology
[0002] Before lining, a fabric-laying trolley is needed to lay waterproof fabric on the tunnel's initial lining. Currently, the mainstream fabric-laying trolley mainly consists of a pair of arched gantry frames, a gantry trolley, and a laying trolley. The gantry trolley can move along the arched gantry frames within the tunnel's cross-section. The gantry trolley has longitudinal beams, and the laying trolley is slidably mounted on the longitudinal beams for laying the waterproof fabric.
[0003] The existing fabric hanging trolley has the following problems: Since the length of the longitudinal beam is equal to the length of each section of the initial lining, which is 12 meters, while the width of the waterproof fabric and the trolley is only 4 meters (there are also 6-meter wide ones, but the common one is 4 meters wide), the trolley must be moved manually every time a waterproof fabric is laid, which is not only time-consuming and labor-intensive, but also poses a safety risk. Utility Model Content
[0004] To overcome the shortcomings of the prior art, this utility model discloses a trolley translation mechanism, which adopts the following technical solution:
[0005] A fabric-laying trolley translation mechanism relates to a fabric-laying trolley, the fabric-laying trolley including a pair of arched gantry frames and a gantry trolley disposed between the pair of arched gantry frames, the gantry trolley having a longitudinal beam, the fabric-laying trolley being disposed on the longitudinal beam, and a winch, wire rope and pulley being disposed on the gantry trolley for traction of the fabric-laying trolley translation on the longitudinal beam.
[0006] Further improvement of the technical solution: The longitudinal beam is a square tube, and the laying trolley has a square sleeve, which is fitted onto the longitudinal beam and can slide relative to the longitudinal beam.
[0007] Further improve the technical solution: A self-lubricating graphite copper plate is installed between the square sleeve and the longitudinal beam.
[0008] Further improved technical solution: The pulley includes a reversing pulley, the winch is set at one end of the gantry trolley, and the reversing pulley is set at the other end of the gantry trolley.
[0009] Further improvement of the technical solution: The pulley includes a pair of guide pulleys, which are respectively set at both ends of the gantry trolley.
[0010] Further technical improvements: Flexible bolts are installed at both ends of the laying trolley. These flexible bolts are used to fix and tighten the wire rope.
[0011] After implementing the above technical solution, the beneficial effects of this utility model compared to the prior art are:
[0012] This utility model is equipped with a winch, wire rope and pulley on the gantry trolley for pulling the laying trolley to move horizontally on the longitudinal beam. After the laying trolley completes the laying of one piece of waterproof cloth, it is only necessary to press the control button to move the laying trolley to the next laying position by the traction of the winch, so that the laying of 12 meters of waterproof cloth can be completed continuously.
[0013] This invention eliminates the need for manual movement of the laying trolley, saving time and effort while also eliminating safety risks. Attached Figure Description

[0022] A trolley translation mechanism for laying fabric is disclosed, relating to the field of tunnel construction equipment technology, and is mainly used to solve the problem that existing fabric-laying trolleys require manual movement of the trolley.
[0023] See attached document Figure 1 This trolley-laying translation mechanism is a component of the fabric-laying trolley, which mainly consists of a gantry trolley 2, a fabric-laying trolley 3, and a pair of arched gantry frames 1. The arched gantry frames 1 are made of bent I-beams. The gantry trolley 2 mainly consists of a pair of trolley frames 21 and a longitudinal beam 22 positioned between the trolley frames 21. The trolley frames 21 have wheels and can move along the arched gantry frames 1 within the tunnel's cross-section. The longitudinal beam 22 is over 12 meters long, and the fabric-laying trolley 3 is approximately 4 meters long. The fabric-laying trolley 3 is slidably mounted on the longitudinal beam 22 for laying the waterproof fabric.
[0024] To address the issue of manually moving the trolley during fabric installation, a winch 4, a wire rope 5, and multiple pulleys are installed on the gantry trolley 2 to pull the trolley 3 horizontally along the longitudinal beam 22.
[0025] See attached document Figure 2-3In this embodiment, the longitudinal beam 22 is a 12-meter-long square tube. The laying trolley 3 mainly consists of a square sleeve 31, a fabric hanging roller 33 mounted on the square sleeve 31, and multiple fabric hanging wheels 32. The 4-meter-long square sleeve 31 is fitted onto the longitudinal beam 22 and can slide relative to the longitudinal beam 22. The fabric hanging roller 33 is located on the side of the square sleeve 31 and is used to install the waterproof fabric roll. The fabric hanging wheels 32 are located on the top of the square sleeve 31 and are used to press the waterproof fabric against the inner wall of the tunnel. To reduce the sliding friction between the square sleeve 31 and the longitudinal beam 22, a self-lubricating graphite copper plate is provided between the square sleeve 31 and the longitudinal beam 22. The self-lubricating graphite copper plate can effectively reduce the sliding friction between the square sleeve 31 and the longitudinal beam 22.
[0026] See attached document Figure 4-6 The pulleys include a reversing pulley 7 and a guide pulley 6. The winch 4 is located at one end of the gantry trolley 2, the reversing pulley 7 is located at the other end of the gantry trolley 2, and a pair of guide pulleys 6 are located at both ends of the gantry trolley 2. Furthermore, a pair of hinged bolts 34 are provided at both ends of the laying trolley 3. The hinged bolts 34, in conjunction with nuts, have adjustable lengths and are used to fix and tighten the wire rope 5. Thus, the winch 4, wire rope 5, reversing pulley 7, guide pulley 6, and hinged bolts 34 constitute the traction mechanism for reciprocating the laying trolley 3. When the winch 4 rotates clockwise, it pulls the laying trolley 3 to the left via the wire rope 5; when the winch 4 rotates counterclockwise, it pulls the laying trolley 3 to the right via the wire rope 5 and the reversing pulley 7. The winch 4 can be controlled by a control handle.
[0027] During construction, once the laying trolley 3 has finished laying one section of waterproof fabric, simply pressing the control button will allow the winch 4 to pull the laying trolley 3 to the next laying position, thus continuously laying 12 meters of waterproof fabric. This not only saves time and effort but also eliminates safety risks.
[0028] It is worth noting that the content not described in detail in the above embodiments is prior art. It is also worth noting that any additions, subtractions, substitutions, and improvements made by those skilled in the art based on the structure and principles of this utility model should be included within the protection scope of this utility model.
