Description

Technical Field

[0001] The present invention relates to the technical field of tunnel lining installation, and particularly to a tunnel lining installation device. Background Art

[0002] Tunnel lining is a permanent structure for supporting and maintaining the long-term stability and durability of tunnels. Most tunnel linings are mainly formed by casting reinforced concrete, which has large structural dimensions, complex processes, difficult control of safety and quality, slow construction progress and high costs. Therefore, prefabricated tunnel linings are gradually applied to the installation of tunnel linings. As Figure 1 shown, the prefabricated tunnel lining includes a base 1 and an arch wall 2 arranged on the top of the base 1. During installation, the arch wall 2 only needs to be assembled to the top of the base 1 to complete the installation of the tunnel lining. However, during the installation of prefabricated tunnel linings, manual assembly of the base 1 and the arch wall 2 is mainly used, resulting in defects such as low efficiency in the assembly of tunnel linings. Summary of the Invention

[0003] Based on this, the object of the present invention is to provide a tunnel lining installation device, which can realize the mechanization of tunnel lining assembly and improve the assembly efficiency of tunnel linings.

[0004] A tunnel lining installation device includes a first installation trolley and a second installation trolley. The first installation trolley is used to install the arch wall of the tunnel lining to the top of the base, and the second installation trolley is used to install the base of the tunnel lining.

[0005] The tunnel lining installation device of the present invention realizes the mechanization of tunnel lining installation through the first installation trolley and the second installation trolley, improving the installation efficiency and construction progress of tunnel linings.

[0006] Further, the first installation trolley includes a first carrying platform, a fixing mechanism and a driving mechanism arranged on the first carrying platform. The fixing mechanism is used to fix the arch wall and is rotatably connected to the first carrying platform through a first hinge shaft. The driving mechanism drives the fixing mechanism to rotate around the first hinge shaft.

[0007] Further, the fixing mechanism includes a rotating bracket for carrying the arch wall, a fixing frame for fixing the arch wall, and a jacking assembly connected to the fixing frame. The rotating bracket is rotatably connected to the first carrying platform through the first hinge shaft, and the jacking assembly is rotatably connected to the first carrying platform through a second hinge shaft. The driving mechanism includes a first support arranged on the first carrying platform, a pulley arranged on the top of the first support, and a winch arranged on the first carrying platform. The traction rope wound around the winch passes around the pulley and then connects to the rotating bracket.

[0008] Furthermore, the jacking assembly includes a mounting seat and a jacking device arranged on the top of the mounting seat, the jacking end of the jacking device is connected to the fixing frame, and the mounting seat is rotatably connected to the first carrier platform via the second hinge shaft.

[0009] Furthermore, a first limiter is provided on the first carrier platform, and the first limiter is provided at the rear of the first hinge shaft. The first limiter can prevent the first carrier platform from overturning due to the rotation transition of the fixing mechanism.

[0010] Furthermore, the second installation trolley includes a second carrying platform and a lifting mechanism, and the lifting mechanism is arranged on the second carrying platform; the second carrying platform is used to carry the base, and the lifting mechanism is used to lift the base, and the base can be transported and installed through the lifting mechanism.

[0011] Furthermore, the hoisting mechanism is arranged on the second carrying platform through a bracket assembly.

[0012] Furthermore, the bracket assembly includes a second bracket and a third bracket arranged on the second carrier platform; the lifting mechanism includes a track beam and a lifting device slidably connected to the track beam, the rear end of the track beam is connected to the second bracket, and the front end of the track beam is connected to the third bracket and extends to the outside of the second carrier platform, so that the base transferred to the second carrier platform can be lifted and lifted to a designated position to complete the installation through the cooperation of the track beam and the lifting device, thereby realizing the mechanization of the base lifting.

[0013] Furthermore, the hoisting mechanism also includes a second limiter, which is arranged at the front end of the track beam. The second limiter can prevent the hoisting device from sliding out of the track beam, thereby improving the safety of the base during hoisting.

[0014] Furthermore, a balancing block is provided on the second loading platform, and the balancing block is provided at the rear of the second bracket. The balancing block can prevent the second loading platform from tipping over due to the low weight at the rear end when the base is lifted.

[0023] To further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following, in conjunction with the accompanying drawings and preferred embodiments, details the specific embodiments, structures, features and their effects of the present invention as follows:

[0024] The purpose of this embodiment is to provide a tunnel lining installation device, which includes a first installation trolley and a second installation trolley. The first installation trolley is used to install the arch wall 2 of the tunnel lining on the top of the base 1, and the second installation trolley is used to install the base 1 of the tunnel lining. Thus, the mechanization of tunnel lining installation is realized through the first installation trolley and the second installation trolley, and the installation efficiency and construction progress of the tunnel lining are improved.

[0025] As Figure 2 and Figure 3 shown, the first installation trolley includes a first carrier 3. A fixing mechanism, a driving mechanism and a first limiter 13 are arranged on the first carrier 3. The fixing mechanism is used to fix the arch wall 2 and is rotatably connected to the first carrier 3 through a first hinge shaft 9. The driving mechanism drives the fixing mechanism to rotate around the first hinge shaft 9.

[0026] The fixing mechanism includes a rotating bracket 4 for carrying the arch wall 2, a fixing frame 12 for fixing the arch wall 2, and a jacking assembly connected to the fixing frame 12. The rotating bracket 4 is rotatably connected to the first carrier 3 through the first hinge shaft 9, and the jacking assembly is rotatably connected to the first carrier 3 through the second hinge shaft 21. Specifically, the jack 11 is a jack.

[0027] The driving mechanism includes a first bracket 5 provided on the first carrier 3, a pulley 6 provided at the top of the first bracket 5, and a winch 7 provided on the first carrier 3. The towing rope 8 wound around the winch 7 is connected to the rotating bracket 4 after passing around the pulley 6.

[0028] The jacking assembly includes a mounting seat 10 and a jack 11 provided at the top of the mounting seat 10. The jacking end of the jack 11 is connected to the fixing frame 12, and the mounting seat 10 is rotatably connected to the first carrier 3 through the second hinge shaft 21.

[0029] The first limiter 13 is provided at the rear of the first hinge shaft 9, so that the first carrier 3 can be prevented from tipping over due to excessive rotation of the rotating bracket 4 through the first limiter 13.

[0030] As Figure 4 and Figure 5 shown, the second installation trolley includes a second carrier 14, a bracket assembly, a hoisting mechanism, and a balance weight 20. The bracket assembly and the balance weight 20 are both provided on the second carrier 14, and the hoisting mechanism is provided on the bracket assembly; the second carrier 14 is used to carry the base 1, and the hoisting mechanism is used to hoist the base 1.

[0031] The bracket assembly includes a second bracket 15 and a third bracket 16 provided on the second carrier 14; the hoisting mechanism includes a track beam 17, a spreader 18 slidably connected to the track beam 17, and a second limiter 19 provided on the track beam 17. The rear end of the track beam 17 is connected to the second bracket 15, and the front end of the track beam 17 is connected to the third bracket 16 and extends outside the second carrier 14; the second limiter 19 is provided at the front end of the track beam 17. More specifically, the spreader 18 is an electric hoist.

[0032] Moreover, the structures of the second bracket 15 and the third bracket 16 are the same, and the second bracket 15 includes two side arms 22 and a connecting arm 23. The connecting arm 23 is provided between the two side arms 22, and the two side arms 22 are provided on the second carrier 14; the front and rear ends of the track beam 17 are respectively connected to the two connecting arms 23.

[0033] The balance weight 20 is arranged at the rear of the second bracket 15, so that the tipping phenomenon of the second carrier 14 due to the too low weight at its rear end can be avoided through the balance weight 20.

[0034] The specific process of installing the tunnel lining by the tunnel lining installation device of the present invention is as follows:

[0035] (1) After loading the base 1 on the second carrier 14, the second carrier 14 moves to the installation position of the base 1; the lifting device 18 lifts the base 1 and slides along the track beam 17; when the base 1 reaches its installation position, the lifting device 18 installs the base 1 to its installation position.

[0036] (2) Place the arch wall 2 on the rotating bracket 4 and fix it through the fixing frame 12. At this time, the lifting end of the jack 11 extends; then, the winch 7 tightens the towing rope 8, so that the rotating bracket 4 rotates around the first hinge shaft 9 under the pulling force of the towing rope 8. At the same time, the rotating bracket 4 drives the mounting seat 10 to rotate around the second hinge shaft 21 until the arch wall 2 reaches the vertical position; then, the lifting end of the jack 11 contracts. At this time, the arch wall 2 will slowly descend to the base 1 along with the fixing frame 12, thereby completing the assembly of the arch wall 2 and the base 1.

[0037] The above embodiments only represent the relatively preferred implementation modes of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and the present invention also intends to include these changes and modifications.
